The research presented in this article focuses on users who shape the distant edges of markets and currently are not using products and services from a domain– so called potential users. Those users at the peripheries are perceived to contribute more novel information, by which they better reflect shifts in needs and behavior than current users in the core market. Their contributions in collaborative and creative problem-solving processes and how they generate ideas for discontinuous innovations are of particular interest. With an experimental design, we compare ideas from potential and current users and analyze the effects of cognitive distance in collaboration and the utilization of explicit and tacit knowledge. We find potential users to generate more original ideas, particularly when they collaborate with someone experienced within the domain. Their ideas are most obviously characterized by an increased level of surprise and unusualness compared to dominant designs, which is rooted in contexts and does not require technological leaps. Collaboration with potential users can therefore result in new ways to leverage technological competences. Furthermore, the cross-fertilization arising from cognitive distance between a potential and a current user is asymmetric due to differences in the nature of their utilized knowledge and personal objectives. This paper discusses implications for innovation research and the management of early innovation processes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=user%20collaboration" title="user collaboration">user collaboration</a>, <a href="https://publications.waset.org/abstracts/search?q=co-creation" title=" co-creation"> co-creation</a>, <a href="https://publications.waset.org/abstracts/search?q=discontinuous%20innovation" title=" discontinuous innovation"> discontinuous innovation</a>, <a href="https://publications.waset.org/abstracts/search?q=innovation%20research" title=" innovation research"> innovation research</a> </p> <a href="https://publications.waset.org/abstracts/19678/innovative-ideas-through-collaboration-with-potential-users" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19678.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">505</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">29</span> The Influence of Consumer and Brand-Oriented Capabilities on Business Performance in Young Firms: A Quantitative Causal Model Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Katharina%20Buttenberg">Katharina Buttenberg</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Customer and brand-oriented capabilities have been identified as key influencing capabilities for business performance.

These processes correspond to the classic understanding of Europeanization, namely a “top-down” stream of influence from the European to the national and subnational levels. However, both minority and disability rights movements also show instances of “bottom-up” Europeanization, e.g. transnational advocacy networks and efforts to reach joint goals at the EU-level. This paper aims to provide a comparative perspective on Europeanization in both fields, pointing out similar dynamics and patterns, but also explaining in which sectors outcomes may be different and which domestic and other scope conditions may be responsible for these differences. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=europeanization" title="europeanization">europeanization</a>, <a href="https://publications.waset.org/abstracts/search?q=disability%20rights" title=" disability rights"> disability rights</a>, <a href="https://publications.waset.org/abstracts/search?q=minority%20rights" title=" minority rights"> minority rights</a>, <a href="https://publications.waset.org/abstracts/search?q=comparative%20perspective" title=" comparative perspective"> comparative perspective</a> </p> <a href="https://publications.waset.org/abstracts/37362/the-europeanization-of-minority-and-disability-rights-a-comparative-view" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37362.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">417</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">27</span> Solid Particle Erosion of Heat Treated TNB-V4 at Ambient and Elevated Temperatures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Naveed">Muhammad Naveed</a>, <a href="https://publications.waset.org/abstracts/search?q=Richard%20Stechow"> Richard Stechow</a>, <a href="https://publications.waset.org/abstracts/search?q=Sebastian%20Bolz"> Sebastian Bolz</a>, <a href="https://publications.waset.org/abstracts/search?q=Katharina%20Hobusch"> Katharina Hobusch</a>, <a href="https://publications.waset.org/abstracts/search?q=Sabine%20Wei%C3%9F"> Sabine Weiß</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Solid particle erosion has been identified as a critical wear phenomenon which takes place during operation of aeroengines in dusty environment. The present work discusses the erosion behavior of Ti-44.5Al-6.25Nb-0.8Mo-0.1B alloy (TNB-V4) which finds its application in low pressure gas turbines and can be used for high pressure compressors too. Prior to the erosion tests, the alloy was heat treated to improve the mechanical properties. Afterwards, specimens were eroded at impact angles of 30° and 90° at room and high temperatures (100 °C-400 °C). Volume loss and erosion behavior are studied through gravimetric analysis, whereas erosion mechanisms are characterized through scanning electron microscopy. The results indicate a clear difference in the erosion mechanism for different impact angles. The influence of the test temperature on the erosion behavior of the alloy is also discussed in the present contribution. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=solid%20particle%20erosion" title="solid particle erosion">solid particle erosion</a>, <a href="https://publications.waset.org/abstracts/search?q=gamma%20TiAl" title=" gamma TiAl"> gamma TiAl</a>, <a href="https://publications.waset.org/abstracts/search?q=TNB-V4" title=" TNB-V4"> TNB-V4</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20temperature%20erosion" title=" high temperature erosion"> high temperature erosion</a> </p> <a href="https://publications.waset.org/abstracts/49747/solid-particle-erosion-of-heat-treated-tnb-v4-at-ambient-and-elevated-temperatures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49747.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">353</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">26</span> Hedonistic Utilitarianism: The Strategic Use of Digital Media along the Online-Offline Continuum of Sexualised Violence</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Katharina%20Kargel">Katharina Kargel</a>, <a href="https://publications.waset.org/abstracts/search?q=Frederic%20Vobbe"> Frederic Vobbe</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present study examines how offenders targeting children and adolescents strategically use digital media when committing acts of sexualised violence along the online-offline continuum. Even offenders who are previously known to their victims use digital media extensively. The choice to instrumentalise digital media in order to initiate, threaten, exploit and humiliate victims demonstrates the rationale of offenders when committing acts of digitally supported violence. Through digital media, offenders can assume the power of interpretation over their victims’ situations. The ways in which digital media is used to commit violence along the online-offline continuum are a direct manifestation of the hedonistic utilitarianism demonstrated by offenders: a disposition characterised by the weighing of pleasures (“mental states”) and intrinsic value expected from using digital media against the risk of an outcome subjectively experienced as uncomfortable. Thus, sexualised violence using digital media goes beyond the traditional understanding of sexual online grooming. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sexualized%20violence" title="sexualized violence">sexualized violence</a>, <a href="https://publications.waset.org/abstracts/search?q=offender%20strategy" title=" offender strategy"> offender strategy</a>, <a href="https://publications.waset.org/abstracts/search?q=grooming" title=" grooming"> grooming</a>, <a href="https://publications.waset.org/abstracts/search?q=children%20and%20adolescents" title=" children and adolescents"> children and adolescents</a>, <a href="https://publications.waset.org/abstracts/search?q=qualitative%20research" title=" qualitative research"> qualitative research</a>, <a href="https://publications.waset.org/abstracts/search?q=methodology" title=" methodology"> methodology</a> </p> <a href="https://publications.waset.org/abstracts/139518/hedonistic-utilitarianism-the-strategic-use-of-digital-media-along-the-online-offline-continuum-of-sexualised-violence" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/139518.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">221</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">25</span> Intuitive Decision Making When Facing Risks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Katharina%20Fellnhofer">Katharina Fellnhofer</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The more information and knowledge that technology provides, the more important are profoundly human skills like intuition, the skill of using nonconscious information. As our world becomes more complex, shaken by crises, and characterized by uncertainty, time pressure, ambiguity, and rapidly changing conditions, intuition is increasingly recognized as a key human asset. However, due to methodological limitations of sample size or time frame or a lack of real-world or cross-cultural scope, precisely how to measure intuition when facing risks on a nonconscious level remains unclear. In light of the measurement challenge related to intuition’s nonconscious nature, a technique is introduced to measure intuition via hidden images as nonconscious additional information to trigger intuition. This technique has been tested in a within-subject fully online design with 62,721 real-world investment decisions made by 657 subjects in Europe and the United States. Bayesian models highlight the technique’s potential to measure skill at using nonconscious information for conscious decision making. Over the long term, solving the mysteries of intuition and mastering its use could be of immense value in personal and organizational decision-making contexts. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cognition" title="cognition">cognition</a>, <a href="https://publications.waset.org/abstracts/search?q=intuition" title=" intuition"> intuition</a>, <a href="https://publications.waset.org/abstracts/search?q=investment%20decisions" title=" investment decisions"> investment decisions</a>, <a href="https://publications.waset.org/abstracts/search?q=methodology" title=" methodology"> methodology</a> </p> <a href="https://publications.waset.org/abstracts/158187/intuitive-decision-making-when-facing-risks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/158187.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">86</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">24</span> When the Children Touched the Paintings: New German Cinema, the Red Army Faction, and their Filmic Afterlives</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rudy%20Ralph%20Martinez">Rudy Ralph Martinez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The 1960s provided us with some of the most iconic protest images of the late-20th century. This was the result of worldwide unrest and the proliferation of filmmaking equipment, which led to a flood of photos and films depicting war and activism. Many of these images and films played a pivotal role in shaping the ever-evolving discussions surrounding the ‘60s. However, too often, radical imagery finds itself subsumed by consumer culture, a degradation that flattens radical imagery and turns it into consumer products. With this in mind, the work that follows is an analysis of one of the little-discussed chapters of the 60s and 70s, and it is that of the New German Cinema movement and its relationship with the Rote Armee Fraktion, or Red Army Faction (RAF), an armed Marxist-Leninist group founded in West Germany in 1970. The RAF arose out of a milieu which included student activists protesting Western military involvement in the Vietnam War, civil rights activists, and third world guerillas. The actions undertaken by the group throughout their first decade in existence, including bombings, and assassinations, would create West Germany’s most dire political crisis since the Nazi era, culminating in a crisis of legitimation remembered as the German Autumn, which saw the suicides of several of the militants and the assassination of SS officer-cum-prominent industrialist, Hans Martin-Schleyer. Throughout the 1970s, young filmmakers associated with the New German Cinema sought to analyze the political situation as it was unfolding, their films contributing to the public discourse in concomitance with the government and the media. Four notable examples of these films are Volker Schlöndorff and Margarethe von Trotta’sDie Verlorene Ehre der Katharina Blum oder: Wie Gewaltentstehen und wohinsieführenkann (The Lost Honour of Katharina Blum, or: How Violence Develops and Where it Can Lead) (1975), a dark drama about the media’s role in forming public opinion, Deutschland im Herbst(Germany in Autumn) (1977), an experimental collective work released mere months after the German Autumn, Rainer Werner Fassbinder’s Die Dritte Generation (The Third Generation) (1979), a satire about an inept cell of radical militants, and Die bleierne Zeit (The Leaden Time, alt. title: Marianne and Juliane) (1981), an intimate portrayal about two sisters whose activism leads them down disparate paths. The filmmakers of the New German Cinema refused to underline their films with the Manichaean claims respectively espoused by the RAF and the government. These complex portrayals found offspring in films such as Christian Petzold’s Die innere Sicherheit(The State I Am In) (2000), a portrait of a family on the run after the reunification of Germany but were countered by glossy high-budget portrayals such as Uli Edel’s Der Baader-Meinhof Komplex(The Baader-Meinhof Complex) (2008). In focusing on the aesthetic structure of these films in relation to the political atmosphere of the late-60s and 70s West Germany, I hope to shed light on questions concerning spectatorship, surveillance, the role of journalism, and how politics disrupts personal relationships, and the kinship between artists and so-called terrorists. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=new%20german%20cinema" title="new german cinema">new german cinema</a>, <a href="https://publications.waset.org/abstracts/search?q=film%20history" title=" film history"> film history</a>, <a href="https://publications.waset.org/abstracts/search?q=red%20army%20faction" title=" red army faction"> red army faction</a>, <a href="https://publications.waset.org/abstracts/search?q=german%20cinema" title=" german cinema"> german cinema</a> </p> <a href="https://publications.waset.org/abstracts/149432/when-the-children-touched-the-paintings-new-german-cinema-the-red-army-faction-and-their-filmic-afterlives" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149432.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">98</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">23</span> Flexible Work Arrangements for Managers-Gender Diversity and Organizational Development in German Firms</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marc%20G%C3%A4rtner">Marc Gärtner</a>, <a href="https://publications.waset.org/abstracts/search?q=Monika%20Huesmann"> Monika Huesmann</a>, <a href="https://publications.waset.org/abstracts/search?q=Katharina%20Schiederig"> Katharina Schiederig</a> </p> <p class="card-text"><strong>Abstract:</strong></p> While workplace flexibility provides opportunities to better balance work and family care, careers in management are still predominantly based on physical presence, blurred boundaries and a culture of availability at the workplace. Thus, carers (mostly women) still experience disadvantages and stalled careers. In a multi-case study, funded by the German Federal Ministry of Education and Research, success factors and barriers of flexible work arrangements in five big organizations, including three of the largest German companies, have been identified. Using qualitative interview methods, the working models of 10 female and male users of flexible work arrangements like part time, home office and job sharing have been studied. The study group applied a 360-degree approach with focus groups, covering the users’ themselves, their superiors, colleagues and staff as well as in-house human resource managers. The group interviews reveal that success of flexible models is mainly built on three factors: (a) the inclusiveness of the organizational culture, (b) the commitment of leaders and especially the supervisors, and (c) the fitting of the model and the user(s). Flexibilization of time and space can indeed contribute to a better work-life balance. This is, however, not a necessary outcome, as the interviews suggest, but depends on the right implementation of the right model in the particular work environment. Beyond the actual study results, the presentation will also assess the methodological approach. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flexible%20work" title="flexible work">flexible work</a>, <a href="https://publications.waset.org/abstracts/search?q=leadership" title=" leadership"> leadership</a>, <a href="https://publications.waset.org/abstracts/search?q=organizational%20culture" title=" organizational culture"> organizational culture</a>, <a href="https://publications.waset.org/abstracts/search?q=work-life%20balance" title=" work-life balance"> work-life balance</a> </p> <a href="https://publications.waset.org/abstracts/39153/flexible-work-arrangements-for-managers-gender-diversity-and-organizational-development-in-german-firms" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39153.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">356</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">22</span> Sustainability in Luxury Hotels: Between a Necessary Evolution and a Way of Differentiation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Katharina%20Schuck">Katharina Schuck</a> </p> <p class="card-text"><strong>Abstract:</strong></p> For a long time, luxury hotels devoted little effort to sustainability, and also scientists were fairly attracted to this subject. While some luxury hotels are now increasingly showing engagement in sustainability, the extent of their commitment varies greatly, which makes the whole industry quite intransparent when it comes to sustainable practices. In general, each hotel companyand each individual hotel can decide for themselves to what extent they commit to sustainability as long as there are no legally prescribed minimum requirements in the respective countries. Despite pleading and compelling calls from industry experts and representatives of relevant sustainability institutions, this is still reality – although climate change and environmental disasters as well as poor treatment of workers and the local population are also issues in progressive and hotel-dense European cities. This paper therefore deals with the question which sustainability activities (environmental and social) have been established by European luxury hotels so far and to what extent these activities are rather a way to differentiate in the market or are simply evaluated as part of a necessary adaptation of the luxury hotel industry. For this purpose, interviews were conducted with both industry experts and hotel representatives in order to obtain a diverse picture of the current status. The studyrevealed that a clear agenda is missing so far, which takes luxury hotels by the handand supports them in the process towards more sustainable hotel management. While a large part of the luxury hotels addressed have already established initiatives and activities regarding sustainability, they are extremely diverse, and range from recyclable toiletries use to comprehensive concepts for energy generation. The study's findings provide insights for both practitioners who seek to implement sustainability in a luxury hotel setting as well as offer an extension of the existing research base on sustainability in hospitality. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=luxury%20hospitality" title="luxury hospitality">luxury hospitality</a>, <a href="https://publications.waset.org/abstracts/search?q=qualitative%20research%20methods" title=" qualitative research methods"> qualitative research methods</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20hotels" title=" sustainable hotels"> sustainable hotels</a> </p> <a href="https://publications.waset.org/abstracts/145929/sustainability-in-luxury-hotels-between-a-necessary-evolution-and-a-way-of-differentiation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/145929.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">114</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">21</span> Willingness to Adopt "Green Steel" Products: A Case Study from the Automotive Sector</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hasan%20Muslemani">Hasan Muslemani</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeffrey%20Wilson"> Jeffrey Wilson</a>, <a href="https://publications.waset.org/abstracts/search?q=Xi%20Liang"> Xi Liang</a>, <a href="https://publications.waset.org/abstracts/search?q=Francisco%20Ascui"> Francisco Ascui</a>, <a href="https://publications.waset.org/abstracts/search?q=Katharina%20Kaesehage"> Katharina Kaesehage</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper aims to examine consumer behaviour towards, and the willingness to adopt, green steel use in the automotive sector, in order to identify potential barriers and opportunities for its widespread adoption. Semi-structured interviews were held with experts from global, regional and country-specific industry associations and automakers. The analysis shows there is a new shift towards lifecycle thinking in the sector, although these efforts have been voluntary and driven by customer and employee pressures rather than regulation. The paper further appraises possible demand for green steel within different vehicle types (based on size and powertrain), and shows that manufacturers of electric heavy-duty vehicles are most likely to adopt green steel in the first instance, given the amount of incorporated steel in the vehicles and the fact that lifecycle emissions lie predominantly in their manufacturing phase. A case for green advanced higher-strength steels (AHSS) can also be made in light-duty passenger vehicles, which may mitigate competition from light-weight alternative materials in terms of cost and greenness (depending on source and utilisation zones). This work builds on a wide sustainability-related literature in the automotive sector and highlights areas in need of urgent action if the sector as a whole were to meet its Paris Agreement climate targets, in particular a need to revisit current CO2 performance regulations to include Scope 1 and Scope 2 emissions, engage in educational green marketing campaigns, and explore innovative market-based mechanisms to bridge the gap between relatively-low carbon abatement costs of steelmaking and high abatement costs of vehicle manufacturing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Green%20steel" title="Green steel">Green steel</a>, <a href="https://publications.waset.org/abstracts/search?q=Consumer%20behaviour" title=" Consumer behaviour"> Consumer behaviour</a>, <a href="https://publications.waset.org/abstracts/search?q=Automotive%20industry" title=" Automotive industry"> Automotive industry</a>, <a href="https://publications.waset.org/abstracts/search?q=Environmental%20sustainability" title=" Environmental sustainability"> Environmental sustainability</a> </p> <a href="https://publications.waset.org/abstracts/133156/willingness-to-adopt-green-steel-products-a-case-study-from-the-automotive-sector" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/133156.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">164</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">20</span> Distraction from Pain: An fMRI Study on the Role of Age-Related Changes in Executive Functions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Katharina%20M.%20Rischer">Katharina M.

The analgesic effects of distraction result from competition for attentional resources in the prefrontal cortex (PFC), a region that is also involved in executive functions. Given that the PFC shows pronounced age-related atrophy, distraction may be less effective in reducing pain in older compared to younger adults. The aim of this study was to investigate the influence of aging on task-related analgesia and the underpinning neural mechanisms, with a focus on the role of executive functions in distraction from pain. In a first session, 64 participants (32 young adults: 26.69 ± 4.14 years; 32 older adults: 68.28 ± 7.00 years) completed a battery of neuropsychological tests. In a second session, participants underwent a pain distraction paradigm, while fMRI images were acquired. In this paradigm, participants completed a low (0-back) and a high (2-back) load condition of a working memory task while receiving either warm or painful thermal stimuli to their lower arm. To control for age-related differences in sensitivity to pain and perceived task difficulty, stimulus intensity, and task speed were individually calibrated. Results indicate that both age groups showed significantly reduced activity in a network of regions involved in pain processing when completing the high load distraction task; however, young adults showed a larger neural distraction effect in different parts of the insula and the thalamus. Moreover, better executive functions, in particular inhibitory control abilities, were associated with a larger behavioral and neural distraction effect. These findings clearly demonstrate that top-down control of pain is affected in older age, and could explain the higher vulnerability for older adults to develop chronic pain. Moreover, our findings suggest that the assessment of executive functions may be a useful tool for predicting the efficacy of cognitive pain modulation strategies in older adults. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=executive%20functions" title="executive functions">executive functions</a>, <a href="https://publications.waset.org/abstracts/search?q=cognitive%20pain%20modulation" title=" cognitive pain modulation"> cognitive pain modulation</a>, <a href="https://publications.waset.org/abstracts/search?q=fMRI" title=" fMRI"> fMRI</a>, <a href="https://publications.waset.org/abstracts/search?q=PFC" title=" PFC"> PFC</a> </p> <a href="https://publications.waset.org/abstracts/121921/distraction-from-pain-an-fmri-study-on-the-role-of-age-related-changes-in-executive-functions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/121921.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">144</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">19</span> Evaluation of Different Anticoagulant Effects on Flow Properties of Human Blood Using Falling Needle Rheometer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hiroki%20Tsuneda">Hiroki Tsuneda</a>, <a href="https://publications.waset.org/abstracts/search?q=Takamasa%20Suzuki"> Takamasa Suzuki</a>, <a href="https://publications.waset.org/abstracts/search?q=Hideki%20Yamamoto"> Hideki Yamamoto</a>, <a href="https://publications.waset.org/abstracts/search?q=Kimito%20Kawamura"> Kimito Kawamura</a>, <a href="https://publications.waset.org/abstracts/search?q=Eiji%20Tamura"> Eiji Tamura</a>, <a href="https://publications.waset.org/abstracts/search?q=Katharina%20Wochner"> Katharina Wochner</a>, <a href="https://publications.waset.org/abstracts/search?q=Roberto%20Plasenzotti"> Roberto Plasenzotti</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Flow property of human blood is one of the important factors on the prevention of the circulatory condition such as a high blood pressure, a diabetes mellitus, and a cardiac infarction. However, the measurement of flow property of human blood, especially blood viscosity, is not so easy, because of their coagulation or aggregation behaviors after taking a sample from blood vessel. In the experiment, some kinds of anticoagulant were added into the human blood to avoid its solidification. Anticoagulant used in the blood test has been chosen for each purpose of blood test, for anticoagulant effect on blood is different mechanism for each. So that, there is a problem that the evaluation of measured blood property with different anticoagulant is so difficult. Therefore, it is so important to make clear the difference of anticoagulant effect on the blood property. In the previous work, a compact-size falling needle rheometer (FNR) has been developed in order to measure the flow property of human blood such as a flow curve, an apparent viscosity. It was found that FNR system can apply to a rheometer or a viscometry for various experimental conditions for not only human blood but also mammalians blood. In this study, the measurements of human blood viscosity with different anticoagulant (EDTA and Heparin) were carried out using newly developed FNR system. The effect of anticoagulant on blood viscosity was also tested by using the standard liquid for each. The accuracy on the viscometry was also tested by using the standard liquid for calibrating materials (JS-10, JS-20) and observed data have satisfactory agreement with reference data around 1.0% at 310K. The flow curve of six males and females with different anticoagulant were measured using FNR. In this experiment, EDTA and Heparin were chosen as anticoagulant for blood. Heparin can inhibit the coagulation of human blood by activating the body of anti-thrombin. To examine the effect of human blood viscosity on anticoagulant, flow curve was measured at high shear rate (＞350s-1), and apparent viscosity of each person were determined with different anticoagulant. The apparent viscosity of human blood with heparin was 2%-9% higher than that with EDTA. However, the difference of blood viscosity for two anticoagulants for same blood was different for each. Further discussion, we need the consideration of effect on other physical property, such as cellular component and plasma component. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=falling-needle%20rheometer" title="falling-needle rheometer">falling-needle rheometer</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20blood" title=" human blood"> human blood</a>, <a href="https://publications.waset.org/abstracts/search?q=viscosity" title=" viscosity"> viscosity</a>, <a href="https://publications.waset.org/abstracts/search?q=anticoagulant" title=" anticoagulant"> anticoagulant</a> </p> <a href="https://publications.waset.org/abstracts/35527/evaluation-of-different-anticoagulant-effects-on-flow-properties-of-human-blood-using-falling-needle-rheometer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35527.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">442</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18</span> Entrepreneurship Education Revised: Merging a Theory-Based and Action-Based Framework for Entrepreneurial Narratives' Impact as an Awareness-Raising Teaching Tool</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Katharina%20Fellnhofer">Katharina Fellnhofer</a>, <a href="https://publications.waset.org/abstracts/search?q=Kaisu%20Puumalainen"> Kaisu Puumalainen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Despite the current worldwide increasing interest in entrepreneurship education (EE), little attention has been paid to innovative web-based ways such as the narrative approach by telling individual stories of entrepreneurs via multimedia for demonstrating the impact on individuals towards entrepreneurship. In addition, this research discipline is faced with no consensus regarding its effective content of teaching materials and tools. Therefore, a qualitative hypothesis-generating research contribution is required to aim at drawing new insights from published works in the EE field of research to serve for future research related to multimedia entrepreneurial narratives. Based on this background, our effort will focus on finding support regarding following introductory statement: Multimedia success and failure stories of real entrepreneurs show potential to change perceptions towards entrepreneurship in a positive way. The proposed qualitative conceptual paper will introduce the underlying background for this research framework. Therefore, as a qualitative hypothesis-generating research contribution it aims at drawing new insights from published works in the EE field of research related to entrepreneurial narratives to serve for future research. With the means of the triangulation of multiple theories, we will utilize the foundation for multimedia-based entrepreneurial narratives applying a learning-through-multimedia-real-entrepreneurial-narratives pedagogical tool to facilitate entrepreneurship. Our effort will help to demystify how value-oriented entrepreneurs telling their stories multimedia can simultaneously enhance EE. Therefore, the paper will build new-fangled bridges between well-cited theoretical constructs to build a robust research framework. Overall, the intended contribution seeks to emphasize future research of currently under-researched issues in the EE sphere, which are considered to be essential not only to academia, as well as to business and society having future jobs-providing growth-oriented entrepreneurs in mind.

That automatic processing plays an essential role in the development and maintenance of symptoms. The aim of our study was, therefore, to investigate the behavioral and neural correlates of automatic processing of trauma-related stimuli in PTSD. Although interpersonal traumatization is a form of traumatization that often occurs, it has not yet been sufficiently studied. That is why, in our study, we focused on patients suffering from interpersonal traumatization. While previous imaging studies on PTSD mainly used faces, words, or generally negative visual stimuli, our study presented complex trauma-related and neutral visual scenes. We examined 19 female subjects suffering from PTSD and examined 19 healthy women as a control group. All subjects did a geometric comparison task while lying in a functional-magnetic-resonance-imaging (fMRI) scanner. Trauma-related scenes and neutral visual scenes that were not relevant to the task were presented while the subjects were doing the task. Regarding the behavioral level, there were not any significant differences between the task performance of the two groups. Regarding the neural level, the PTSD patients showed significant hyperactivation of the hippocampus for task-irrelevant trauma-related stimuli versus neutral stimuli when compared with healthy control subjects. Connectivity analyses revealed altered connectivity between the hippocampus and other anxiety-related areas in PTSD patients, too. Overall, those findings suggest that fear-related areas are involved in PTSD patients' processing of trauma-related stimuli even if the stimuli that were used in the study were task-irrelevant. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=post-traumatic%20stress%20disorder" title="post-traumatic stress disorder">post-traumatic stress disorder</a>, <a href="https://publications.waset.org/abstracts/search?q=automatic%20processing" title=" automatic processing"> automatic processing</a>, <a href="https://publications.waset.org/abstracts/search?q=hippocampus" title=" hippocampus"> hippocampus</a>, <a href="https://publications.waset.org/abstracts/search?q=functional%20magnetic%20resonance%20imaging" title=" functional magnetic resonance imaging"> functional magnetic resonance imaging</a> </p> <a href="https://publications.waset.org/abstracts/140162/automatic-processing-of-trauma-related-visual-stimuli-in-female-patients-suffering-from-post-traumatic-stress-disorder-after-interpersonal-traumatization" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/140162.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">199</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">16</span> Insights into the Annotated Genome Sequence of Defluviitoga tunisiensis L3 Isolated from a Thermophilic Rural Biogas Producing Plant</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Irena%20Maus">Irena Maus</a>, <a href="https://publications.waset.org/abstracts/search?q=Katharina%20Gabriella%20Cibis"> Katharina Gabriella Cibis</a>, <a href="https://publications.waset.org/abstracts/search?q=Andreas%20Bremges"> Andreas Bremges</a>, <a href="https://publications.waset.org/abstracts/search?q=Yvonne%20Stolze"> Yvonne Stolze</a>, <a href="https://publications.waset.org/abstracts/search?q=Geizecler%20Tomazetto"> Geizecler Tomazetto</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Wibberg"> Daniel Wibberg</a>, <a href="https://publications.waset.org/abstracts/search?q=Helmut%20K%C3%B6nig"> Helmut König</a>, <a href="https://publications.waset.org/abstracts/search?q=Alfred%20P%C3%BChler"> Alfred Pühler</a>, <a href="https://publications.waset.org/abstracts/search?q=Andreas%20Schl%C3%BCter"> Andreas Schlüter</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Within the agricultural sector, the production of biogas from organic substrates represents an economically attractive technology to generate bioenergy. Complex consortia of microorganisms are responsible for biomass decomposition and biogas production. Recently, species belonging to the phylum Thermotogae were detected in thermophilic biogas-production plants utilizing renewable primary products for biomethanation. To analyze adaptive genome features of representative Thermotogae strains, Defluviitoga tunisiensis L3 was isolated from a rural thermophilic biogas plant (54°C) and completely sequenced on an Illumina MiSeq system. Sequencing and assembly of the D. tunisiensis L3 genome yielded a circular chromosome with a size of 2,053,097 bp and a mean GC content of 31.38%. Functional annotation of the complete genome sequence revealed that the thermophilic strain L3 encodes several genes predicted to facilitate growth of this microorganism on arabinose, galactose, maltose, mannose, fructose, raffinose, ribose, cellobiose, lactose, xylose, xylan, lactate and mannitol. Acetate, hydrogen (H2) and carbon dioxide (CO2) are supposed to be end products of the fermentation process. The latter gene products are metabolites for methanogenic archaea, the key players in the final step of the anaerobic digestion process. To determine the degree of relatedness of dominant biogas community members within selected digester systems to D. tunisiensis L3, metagenome sequences from corresponding communities were mapped on the L3 genome. These fragment recruitments revealed that metagenome reads originating from a thermophilic biogas plant covered 95% of D. tunisiensis L3 genome sequence. In conclusion, availability of the D. tunisiensis L3 genome sequence and insights into its metabolic capabilities provide the basis for biotechnological exploitation of genome features involved in thermophilic fermentation processes utilizing renewable primary products. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=genome%20sequence" title="genome sequence">genome sequence</a>, <a href="https://publications.waset.org/abstracts/search?q=thermophilic%20biogas%20plant" title=" thermophilic biogas plant"> thermophilic biogas plant</a>, <a href="https://publications.waset.org/abstracts/search?q=Thermotogae" title=" Thermotogae"> Thermotogae</a>, <a href="https://publications.waset.org/abstracts/search?q=Defluviitoga%20tunisiensis" title=" Defluviitoga tunisiensis"> Defluviitoga tunisiensis</a> </p> <a href="https://publications.waset.org/abstracts/29463/insights-into-the-annotated-genome-sequence-of-defluviitoga-tunisiensis-l3-isolated-from-a-thermophilic-rural-biogas-producing-plant" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29463.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">499</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">15</span> Comparison of Cognitive Load in Virtual Reality and Conventional Simulation-Based Training: A Randomized Controlled Trial</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Michael%20Wagner">Michael Wagner</a>, <a href="https://publications.waset.org/abstracts/search?q=Philipp%20Steinbauer"> Philipp Steinbauer</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrea%20Katharina%20Lietz"> Andrea Katharina Lietz</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexander%20Hoffelner"> Alexander Hoffelner</a>, <a href="https://publications.waset.org/abstracts/search?q=Johannes%20Fessler"> Johannes Fessler</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Cardiopulmonary resuscitations are stressful situations in which vital decisions must be made within seconds. Lack of routine due to the infrequency of pediatric emergencies can lead to serious medical and communication errors. Virtual reality can fundamentally change the way simulation training is conducted in the future. It appears to be a useful learning tool for technical and non-technical skills. It is important to investigate the use of VR in providing a strong sense of presence within simulations. Methods: In this randomized study, we will enroll doctors and medical students from the Medical University of Vienna, who will receive learning material regarding the resuscitation of a one-year-old child. The study will be conducted in three phases. In the first phase, 20 physicians and 20 medical students from the Medical University of Vienna will be included. They will perform simulation-based training with a standardized scenario of a critically ill child with a hypovolemic shock. The main goal of this phase is to establish a baseline for the following two phases to generate comparative values regarding cognitive load and stress. In phase 2 and 3, the same participants will perform the same scenario in a VR setting. In both settings, on three set points of progression, one of three predefined events is triggered. For each event, three different stress levels (easy, medium, difficult) will be defined. Stress and cognitive load will be analyzed using the NASA Task Load Index, eye-tracking parameters, and heart rate. Subsequently, these values will be compared between VR training and traditional simulation-based training. Hypothesis: We hypothesize that the VR training and the traditional training groups will not differ in physiological response (cognitive load, heart rate, and heart rate variability). We further assume that virtual reality training can be used as cost-efficient additional training. Objectives: The aim of this study is to measure cognitive load and stress level during a real-life simulation training and compare it with VR training in order to show that VR training evokes the same physiological response and cognitive load as real-life simulation training. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=virtual%20reality" title="virtual reality">virtual reality</a>, <a href="https://publications.waset.org/abstracts/search?q=cognitive%20load" title=" cognitive load"> cognitive load</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=adaptive%20virtual%20reality%20training" title=" adaptive virtual reality training"> adaptive virtual reality training</a> </p> <a href="https://publications.waset.org/abstracts/152955/comparison-of-cognitive-load-in-virtual-reality-and-conventional-simulation-based-training-a-randomized-controlled-trial" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152955.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">115</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">14</span> The Sociocultural, Economic, and Environmental Contestations of Agbogbloshie: A Critical Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khiddir%20Iddris">Khiddir Iddris</a>, <a href="https://publications.waset.org/abstracts/search?q=Martin%20Oteng%20%E2%80%93%20Ababio"> Martin Oteng – Ababio</a>, <a href="https://publications.waset.org/abstracts/search?q=Andreas%20B%C3%BCrkert"> Andreas Bürkert</a>, <a href="https://publications.waset.org/abstracts/search?q=Christoph%20Scherrer"> Christoph Scherrer</a>, <a href="https://publications.waset.org/abstracts/search?q=Katharina%20Hemmler"> Katharina Hemmler</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Agbogbloshie, as an informal settlement and economy where the e-waste sector thrives, has become a global hub of complex urban contestations involving sociocultural, economic, and environmental dimensions due to the implication that e-waste and informal economic patterns have on livelihoods, urbanisation, development and sustainability. Multi-author collaborations have produced an ever-growing body of literature on Agbogbloshie and the informal e-waste economy. There is, however, a dearth of an assessment of Agbogbloshie as an urban informal settlement's intricate nexus of socioecological contestations. We address this gap by systematising, from literature, the context knowledge, navigating the complex terrain of Agbogbloshie's challenges, and employing a multidimensional lens to unravel the sociocultural intricacies, economic dynamics, and environmental complexities shaping its identity. A systematic critical review approach was espoused, with a pragmatic consolidation of content analysis and controversy mapping, grounded on the concept of ‘sustainable rurbanism,’ highlighted core themes and identified contrasting viewpoints. An analytical framework is presented. Five categories – geohistorical, sociocultural, economic, environmental and future trends - are proposed as an approach to systematising the literature. The review finds that the sociocultural dimension unveils a mosaic of cultural amalgamation, communal identity, and tensions impacting community cohesion. The analysis of economic intricacies reveals the prevalence of informal economies sustaining livelihoods yet entrenching economic disparities and marginalisation. Environmental scrutiny exposes the grim realities of e-waste disposal, pollution, and land use conflicts. The findings suggest that there is a high resilience within the community and the potential for sustainable trajectories. Theoretical and conceptual synergy is limited. This review provides a comprehensive exploration, offering insights and directions for future research, policy formulation, and community-driven interventions aimed at fostering sustainable transformations in Agbogbloshie and analogous urban contexts. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Agbogbloshie" title="Agbogbloshie">Agbogbloshie</a>, <a href="https://publications.waset.org/abstracts/search?q=economic%20complexities" title=" economic complexities"> economic complexities</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20challenges" title=" environmental challenges"> environmental challenges</a>, <a href="https://publications.waset.org/abstracts/search?q=resilience" title=" resilience"> resilience</a>, <a href="https://publications.waset.org/abstracts/search?q=sociocultural%20dynamics" title=" sociocultural dynamics"> sociocultural dynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20informal%20settlement" title=" urban informal settlement"> urban informal settlement</a> </p> <a href="https://publications.waset.org/abstracts/178030/the-sociocultural-economic-and-environmental-contestations-of-agbogbloshie-a-critical-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/178030.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">71</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">13</span> Hybrid Strategies of Crisis Intervention for Sexualized Violence Using Digital Media</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Katharina%20Kargel">Katharina Kargel</a>, <a href="https://publications.waset.org/abstracts/search?q=Frederic%20Vobbe"> Frederic Vobbe</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Sexualized violence against children and adolescents using digital media poses particular challenges for practitioners with a focus on crisis intervention (social work, psychotherapy, law enforcement). The technical delimitation of violence increases the burden on those affected and increases the complexity of interdisciplinary cooperation. Urgently needed recommendations for practical action do not yet exist in Germany. Funded by the Federal Ministry of Education and Research, these recommendations for action are being developed in the HUMAN project together with science and practice. The presentation introduces the participatory approach of the HUMAN project. We discuss the application-oriented, casuistic approach of the project and present its results using the example of concrete case-based recommendations for Action. The participants will be presented with concrete prototypical case studies from the project, which will be used to illustrate quality criteria for crisis intervention in cases of sexualized violence using digital media. On the basis of case analyses, focus group interviews and interviews with victims of violence, we present the six central challenges of sexualized violence with the use of digital media, namely: • Diffusion (Ambiguities regarding the extent and significance of violence) , • Transcendence (Space and time independence of the dynamics of violence, omnipresence), • omnipresent anxiety (considering diffusion and transcendence), • being haunted (repeated confrontation with digital memories of violence or the perpetrator), • disparity (conflicts of interpretative power between those affected and the social environment) • simultaneity (of all other factors). We point out generalizable principles with which these challenges can be dealt with professionally. Dealing professionally with sexualized violence using digital media requires a stronger networking of professional actors. A clear distinction must be made between their own mission and the mission of the network partners. Those affected by violence must be shown options for crisis intervention in the context of the aid networks. The different competencies and the professional mission of the offers of help are to be made transparent. The necessity of technical possibilities for deleting abuse images beyond criminal prosecution will be discussed. Those affected are stabilized by multimodal strategies such as a combination of rational emotive therapy, legal support and technical assistance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sexualized%20violence" title="sexualized violence">sexualized violence</a>, <a href="https://publications.waset.org/abstracts/search?q=intervention" title=" intervention"> intervention</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20media" title=" digital media"> digital media</a>, <a href="https://publications.waset.org/abstracts/search?q=children%20and%20youth" title=" children and youth"> children and youth</a> </p> <a href="https://publications.waset.org/abstracts/139520/hybrid-strategies-of-crisis-intervention-for-sexualized-violence-using-digital-media" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/139520.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">234</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12</span> Promoting Self-Esteem and Social Integration in Secondary German Schools: An Evaluation Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Susanne%20Manes">Susanne Manes</a>, <a href="https://publications.waset.org/abstracts/search?q=Anni%20Glaeser"> Anni Glaeser</a>, <a href="https://publications.waset.org/abstracts/search?q=Katharina%20Wick"> Katharina Wick</a>, <a href="https://publications.waset.org/abstracts/search?q=Bernhard%20Strauss"> Bernhard Strauss</a>, <a href="https://publications.waset.org/abstracts/search?q=Uwe%20Berger"> Uwe Berger</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Over the last decades growing rates of mental health concerns among children and adolescents have been observed. At the same time, physical well-being of children and adolescents becomes increasingly impaired as well. Schools play an important role in preventing mental and physical disorders and in promoting well-being. Self-esteem, as well as social integration, are vital influence factors for mental and physical well-being. The purpose of this study was to develop and evaluate the program 'VorteilJena' for secondary schools in Germany focusing on self-esteem and social integration to improve mental and physical well-being. Method: The school-based health promotion program was designed for students in 5th grade and higher. It consists of several short pedagogical exercises instructed by a teacher and were integrated into the regular class over the course of ten weeks. The exercises focused on fostering social integration using either tasks improving team spirit or exercises that increase tolerance and sense of belonging. Other exercises focused on strengthening the self-esteem of the students. Additionally, the program included a poster exhibition titled 'Belonging' which was put up in the school buildings. The exhibition comprised ten posters which addressed relevant risk factors and resources related to social integration and self-esteem. The study was a randomized controlled sequential study with a pre and post measurement conducted in ten German schools. A total of 1642 students (44% male) were recruited. Their age ranged from 9 to 21 years (M=12.93 years; SD= 2.11). The program was conducted in classes ranging from 5th to 12th grade. Results: The program improved wellbeing, self-esteem and social integration of the involved students compared to the control group. Differential effects depending on implementation rates or age of the students will be analyzed. Moreover, implications for future school-based health promotion programs targeting self-esteem and social integration will be discussed. Conclusion: Social integration considerably influences self-esteem and well-being of students and can be targeted by school-based programs including short and modest exercises. Since a sufficient implementation of health promotion programs is essential, the present program due to its practicability represents a good opportunity to install health promotion focusing on social integration in schools. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=social%20integration" title="social integration">social integration</a>, <a href="https://publications.waset.org/abstracts/search?q=well-being" title=" well-being"> well-being</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20promotion%20in%20schools" title=" health promotion in schools"> health promotion in schools</a>, <a href="https://publications.waset.org/abstracts/search?q=self-esteem" title=" self-esteem "> self-esteem </a> </p> <a href="https://publications.waset.org/abstracts/92669/promoting-self-esteem-and-social-integration-in-secondary-german-schools-an-evaluation-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92669.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">197</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">11</span> Scaling out Sustainable Land Use Systems in Colombia: Some Insights and Implications from Two Regional Case Studies </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Martha%20Lilia%20Del%20Rio%20Duque">Martha Lilia Del Rio Duque</a>, <a href="https://publications.waset.org/abstracts/search?q=Michelle%20Bonatti"> Michelle Bonatti</a>, <a href="https://publications.waset.org/abstracts/search?q=Katharina%20Loehr"> Katharina Loehr</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcos%20Lana"> Marcos Lana</a>, <a href="https://publications.waset.org/abstracts/search?q=Tatiana%20Rodriguez"> Tatiana Rodriguez</a>, <a href="https://publications.waset.org/abstracts/search?q=Stefan%20Sieber"> Stefan Sieber</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays, most agricultural practices can reduce the ability of ecosystems to provide goods and services. To enhance environmentally friendly food production and to maximize social and economic benefits, sustainable land use systems (SLUS) are one of the most critical strategies increasingly/strongly promoted by donors organizations, international agencies, and policymakers. This process involves the question of how SLUS can be scaled out also large-scale landscapes and not merely isolated experiments. As SLUS are context-specific strategies, diffusion and replication of successful SLUS in Colombia required the identification of main factors that facilitate this scaling out process. We applied a case study approach to investigate the scaling out process of SLUS in cocoa and livestock sector within peacebuilding territories in Colombia, specifically, in Cesar and Caqueta region. These two regions are contrasting, but both have a current trend of increasing land degradation. Presently in Colombia, Caqueta is one of the most deforested departments, and Cesar has some most degraded soils. Following a qualitative research approach, 19 semi-structured interviews and 2 focus groups were conducted with agroforestry experts in both regions to analyze (1) what does it mean a sustainable land use system in Cocoa/Livestock, specifically in Caqueta or Cesar and (2) to identify the key elements at the level of the following dimensions: biophysical, economic and profitability, market, social, policy and institutions that can explain how and why SLUS are replicated and spread among more producers. The Interviews were coded and analyzed using MAXQDA to identify, analyze and report patterns (themes) within data. As the results show, key themes, among which: premium market, solid regional markets and price stability, water availability and management, generational renewal, land use knowledge and diversification, producer organization and certifications are crucial to understand how the SLUS can have an impact across large-scale landscapes and how the scaling out process can be set up best in order to be successful across different contexts. The analysis further reveals which key factors might affect SLUS efficiency. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agroforestry" title="agroforestry">agroforestry</a>, <a href="https://publications.waset.org/abstracts/search?q=cocoa%20sector" title=" cocoa sector"> cocoa sector</a>, <a href="https://publications.waset.org/abstracts/search?q=Colombia" title=" Colombia"> Colombia</a>, <a href="https://publications.waset.org/abstracts/search?q=livestock%20sector" title=" livestock sector"> livestock sector</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20land%20use%20system" title=" sustainable land use system"> sustainable land use system</a> </p> <a href="https://publications.waset.org/abstracts/129873/scaling-out-sustainable-land-use-systems-in-colombia-some-insights-and-implications-from-two-regional-case-studies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/129873.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">160</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">10</span> Angiomotin Regulates Integrin Beta 1-Mediated Endothelial Cell Migration and Angiogenesis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yuanyuan%20Zhang">Yuanyuan Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yujuan%20Zheng"> Yujuan Zheng</a>, <a href="https://publications.waset.org/abstracts/search?q=Giuseppina%20Barutello"> Giuseppina Barutello</a>, <a href="https://publications.waset.org/abstracts/search?q=Sumako%20Kameishi"> Sumako Kameishi</a>, <a href="https://publications.waset.org/abstracts/search?q=Kungchun%20Chiu"> Kungchun Chiu</a>, <a href="https://publications.waset.org/abstracts/search?q=Katharina%20Hennig"> Katharina Hennig</a>, <a href="https://publications.waset.org/abstracts/search?q=Martial%20Balland"> Martial Balland</a>, <a href="https://publications.waset.org/abstracts/search?q=Federica%20Cavallo"> Federica Cavallo</a>, <a href="https://publications.waset.org/abstracts/search?q=Lars%20Holmgren"> Lars Holmgren</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Angiogenesis describes that new blood vessels migrate from pre-existing ones to form 3D lumenized structure and remodeling. During directional migration toward the gradient of pro-angiogenic factors, the endothelial cells, especially the tip cells need filopodia to sense the environment and exert the pulling force. Of particular interest are the integrin proteins, which play an essential role in focal adhesion in the connection between migrating cells and extracellular matrix (ECM). Understanding how these biomechanical complexes orchestrate intrinsic and extrinsic forces is important for our understanding of the underlying mechanisms driving angiogenesis. We have previously identified Angiomotin (Amot), a member of Amot scaffold protein family, as a promoter for endothelial cell migration in vitro and zebrafish models. Hence, we established inducible endothelial-specific Amot knock-out mice to study normal retinal angiogenesis as well as tumor angiogenesis. We found that the migration ratio of the blood vessel network to the edge was significantly decreased in Amotec- retinas at postnatal day 6 (P6). While almost all the Amot defect tip cells lost migration advantages at P7. In consistence with the dramatic morphology defect of tip cells, there was a non-autonomous defect in astrocytes, as well as the disorganized fibronectin expression pattern correspondingly in migration front. Furthermore, the growth of transplanted LLC tumor was inhibited in Amot knockout mice due to fewer vasculature involved. By using MMTV-PyMT transgenic mouse model, there was a significantly longer period before tumors arised when Amot was specifically knocked out in blood vessels. In vitro evidence showed that Amot binded to beta-actin, Integrin beta 1 (ITGB1), Fibronectin, FAK, Vinculin, major focal adhesion molecules, and ITGB1 and stress fibers were distinctly induced by Amot transfection. Via traction force microscopy, the total energy (force indicater) was found significantly decreased in Amot knockdown cells. Taken together, we propose that Amot is a novel partner of the ITGB1/Fibronectin protein complex at focal adhesion and required for exerting force transition between endothelial cell and extracellular matrix. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=angiogenesis" title="angiogenesis">angiogenesis</a>, <a href="https://publications.waset.org/abstracts/search?q=angiomotin" title=" angiomotin"> angiomotin</a>, <a href="https://publications.waset.org/abstracts/search?q=endothelial%20cell%20migration" title=" endothelial cell migration"> endothelial cell migration</a>, <a href="https://publications.waset.org/abstracts/search?q=focal%20adhesion" title=" focal adhesion"> focal adhesion</a>, <a href="https://publications.waset.org/abstracts/search?q=integrin%20beta%201" title=" integrin beta 1"> integrin beta 1</a> </p> <a href="https://publications.waset.org/abstracts/72725/angiomotin-regulates-integrin-beta-1-mediated-endothelial-cell-migration-and-angiogenesis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72725.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">238</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9</span> The Instrumentalization of Digital Media in the Context of Sexualized Violence</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Katharina%20Kargel">Katharina Kargel</a>, <a href="https://publications.waset.org/abstracts/search?q=Frederic%20Vobbe"> Frederic Vobbe</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Sexual online grooming is generally defined as digital interactions for the purpose of sexual exploitation of children or minors, i.e. as a process for preparing and framing sexual child abuse. Due to its conceptual history, sexual online grooming is often associated with perpetrators who are previously unknown to those affected. While the strategies of perpetrators and the perception of those affected are increasingly being investigated, the instrumentalisation of digital media has not yet been researched much. Therefore, the present paper aims at contributing to this research gap by examining in what kind of ways perpetrators instrumentalise digital media. Our analyses draw on 46 case documentations and 18 interviews with those affected. The cases and the partly narrative interviews were collected by ten cooperating specialist centers working on sexualized violence in childhood and youth. For this purpose, we designed a documentation grid allowing for a detailed case reconstruction i.e. including information on the violence, digital media use and those affected. By using Reflexive Grounded Theory, our analyses emphasize a) the subjective benchmark of professional practitioners as well as those affected and b) the interpretative implications resulting from our researchers’ subjective and emotional interaction with the data material. It should first be noted that sexualized online grooming can result in both online and offline sexualized violence as well as hybrid forms. Furthermore, the perpetrators either come from the immediate social environment of those affected or are unknown to them. The perpetrator-victim relationship plays a more important role with regard to the question of the instrumentalisation of digital media than the question of the space (on vs. off) in which the primary violence is committed. Perpetrators unknown to those affected instrumentalise digital media primarily to establish a sexualized system of norms, which is usually embedded in a supposed love relationship. In some cases, after an initial exchange of sexualized images or video recordings, a latent play on the position of power takes place. In the course of the grooming process, perpetrators from the immediate social environment increasingly instrumentalise digital media to establish an explicit relationship of power and dependence, which is directly determined by coercion, threats and blackmail. The knowledge of possible vulnerabilities is strategically used in the course of maintaining contact. The above explanations lead to the conclusion that the motive for the crime plays an essential role in the question of the instrumentalisation of digital media. It is therefore not surprising that it is mostly the near-field perpetrators without commercial motives who initiate a spiral of violence and stress by digitally distributing sexualized (violent) images and video recordings within the reference system of those affected. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sexualized%20violence" title="sexualized violence">sexualized violence</a>, <a href="https://publications.waset.org/abstracts/search?q=children%20and%20youth" title=" children and youth"> children and youth</a>, <a href="https://publications.waset.org/abstracts/search?q=grooming" title=" grooming"> grooming</a>, <a href="https://publications.waset.org/abstracts/search?q=offender%20strategies" title=" offender strategies"> offender strategies</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20media" title=" digital media"> digital media</a> </p> <a href="https://publications.waset.org/abstracts/139521/the-instrumentalization-of-digital-media-in-the-context-of-sexualized-violence" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/139521.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">184</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8</span> Bi-objective Network Optimization in Disaster Relief Logistics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Katharina%20Eberhardt">Katharina Eberhardt</a>, <a href="https://publications.waset.org/abstracts/search?q=Florian%20Klaus%20Kaiser"> Florian Klaus Kaiser</a>, <a href="https://publications.waset.org/abstracts/search?q=Frank%20Schultmann"> Frank Schultmann</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Last-mile distribution is one of the most critical parts of a disaster relief operation. Various uncertainties, such as infrastructure conditions, resource availability, and fluctuating beneficiary demand, render last-mile distribution challenging in disaster relief operations. The need to balance critical performance criteria like response time, meeting demand and cost-effectiveness further complicates the task. The occurrence of disasters cannot be controlled, and the magnitude is often challenging to assess. In summary, these uncertainties create a need for additional flexibility, agility, and preparedness in logistics operations. As a result, strategic planning and efficient network design are critical for an effective and efficient response. Furthermore, the increasing frequency of disasters and the rising cost of logistical operations amplify the need to provide robust and resilient solutions in this area. Therefore, we formulate a scenario-based bi-objective optimization model that integrates pre-positioning, allocation, and distribution of relief supplies extending the general form of a covering location problem. The proposed model aims to minimize underlying logistics costs while maximizing demand coverage. Using a set of disruption scenarios, the model allows decision-makers to identify optimal network solutions to address the risk of disruptions. We provide an empirical case study of the public authorities’ emergency food storage strategy in Germany to illustrate the potential applicability of the model and provide implications for decision-makers in a real-world setting. Also, we conduct a sensitivity analysis focusing on the impact of varying stockpile capacities, single-site outages, and limited transportation capacities on the objective value. The results show that the stockpiling strategy needs to be consistent with the optimal number of depots and inventory based on minimizing costs and maximizing demand satisfaction. The strategy has the potential for optimization, as network coverage is insufficient and relies on very high transportation and personnel capacity levels. As such, the model provides decision support for public authorities to determine an efficient stockpiling strategy and distribution network and provides recommendations for increased resilience. However, certain factors have yet to be considered in this study and should be addressed in future works, such as additional network constraints and heuristic algorithms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=humanitarian%20logistics" title="humanitarian logistics">humanitarian logistics</a>, <a href="https://publications.waset.org/abstracts/search?q=bi-objective%20optimization" title=" bi-objective optimization"> bi-objective optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=pre-positioning" title=" pre-positioning"> pre-positioning</a>, <a href="https://publications.waset.org/abstracts/search?q=last%20mile%20distribution" title=" last mile distribution"> last mile distribution</a>, <a href="https://publications.waset.org/abstracts/search?q=decision%20support" title=" decision support"> decision support</a>, <a href="https://publications.waset.org/abstracts/search?q=disaster%20relief%20networks" title=" disaster relief networks"> disaster relief networks</a> </p> <a href="https://publications.waset.org/abstracts/162169/bi-objective-network-optimization-in-disaster-relief-logistics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162169.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">79</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7</span> Using a Card Game as a Tool for Developing a Design</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Matthias%20Haenisch">Matthias Haenisch</a>, <a href="https://publications.waset.org/abstracts/search?q=Katharina%20Hermann"> Katharina Hermann</a>, <a href="https://publications.waset.org/abstracts/search?q=Marc%20Godau"> Marc Godau</a>, <a href="https://publications.waset.org/abstracts/search?q=Verena%20Weidner"> Verena Weidner</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Over the past two decades, international music education has been characterized by a growing interest in informal learning for formal contexts and a "compositional turn" that has moved from closed to open forms of composing. This change occurs under social and technological conditions that permeate 21st-century musical practices. This forms the background of Musical Communities in the (Post)Digital Age (MusCoDA), a four-year joint research project of the University of Erfurt (UE) and the University of Education Karlsruhe (PHK), funded by the German Federal Ministry of Education and Research (BMBF). Both explore songwriting processes as an example of collective creativity in (post)digital communities, one in formal and the other in informal learning contexts. Collective songwriting will be studied from a network perspective, that will allow us to view boundaries between both online and offline as well as formal and informal or hybrid contexts as permeable and to reconstruct musical learning practices. By comparing these songwriting processes, possibilities for a pedagogical-didactic interweaving of different educational worlds are highlighted. Therefore, the subproject of the University of Erfurt investigates school music lessons with the help of interviews, videography, and network maps by analyzing new digital pedagogical and didactic possibilities. In the first step, the international literature on songwriting in the music classroom was examined for design development. The analysis focused on the question of which methods and practices are circulating in the current literature. Results from this stage of the project form the basis for the first instructional design that will help teachers in planning regular music classes and subsequently reconstruct musical learning practices under these conditions. In analyzing the literature, we noticed certain structural methods and concepts that recur, such as the Building Blocks method and the pre-structuring of the songwriting process. From these findings, we developed a deck of cards that both captures the current state of research and serves as a method for design development. With this deck of cards, both teachers and students themselves can plan their individual songwriting lessons by independently selecting and arranging topic, structure, and action cards. In terms of science communication, music educators' interactions with the card game provide us with essential insights for developing the first design. The overall goal of MusCoDA is to develop an empirical model of collective musical creativity and learning and an instructional design for teaching music in the postdigital age. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=card%20game" title="card game">card game</a>, <a href="https://publications.waset.org/abstracts/search?q=collective%20songwriting" title=" collective songwriting"> collective songwriting</a>, <a href="https://publications.waset.org/abstracts/search?q=community%20of%20practice" title=" community of practice"> community of practice</a>, <a href="https://publications.waset.org/abstracts/search?q=network" title=" network"> network</a>, <a href="https://publications.waset.org/abstracts/search?q=postdigital" title=" postdigital"> postdigital</a> </p> <a href="https://publications.waset.org/abstracts/146534/using-a-card-game-as-a-tool-for-developing-a-design" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146534.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">64</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6</span> Implementing a Prevention Network for the Ortenaukreis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Klaus%20Froehlich-Gildhoff">Klaus Froehlich-Gildhoff</a>, <a href="https://publications.waset.org/abstracts/search?q=Ullrich%20Boettinger"> Ullrich Boettinger</a>, <a href="https://publications.waset.org/abstracts/search?q=Katharina%20Rauh"> Katharina Rauh</a>, <a href="https://publications.waset.org/abstracts/search?q=Angela%20Schickler"> Angela Schickler</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Prevention Network Ortenaukreis, PNO, funded by the German Ministry of Education and Research, aims to promote physical and mental health as well as the social inclusion of 3 to 10 years old children and their families in the Ortenau district. Within a period of four years starting 11/2014 a community network will be established. One regional and five local prevention representatives are building networks with stakeholders of the prevention and health promotion field bridging the health care, educational and youth welfare system in a multidisciplinary approach. The regional prevention representative implements regularly convening prevention and health conferences. On a local level, the 5 local prevention representatives implement round tables in each area as a platform for networking. In the setting approach, educational institutions are playing a vital role when gaining access to children and their families. Thus the project will offer 18 month long organizational development processes with specially trained coaches to 25 kindergarten and 25 primary schools. The process is based on a curriculum of prevention and health promotion which is adapted to the specific needs of the institutions. Also to ensure that the entire region is reached demand oriented advanced education courses are implemented at participating day care centers, kindergartens and schools. Evaluation method: The project is accompanied by an extensive research design to evaluate the outcomes of different project components such as interview data from community prevention agents, interviews and network analysis with families at risk on their support structures, data on community network development and monitoring, as well as data from kindergarten and primary schools. The latter features a waiting-list control group evaluation in kindergarten and primary schools with a mixed methods design using questionnaires and interviews with pedagogues, teachers, parents, and children. Results: By the time of the conference pre and post test data from the kindergarten samples (treatment and control group) will be presented, as well as data from the first project phase, such as qualitative interviews with the prevention coordinators as well as mixed methods data from the community needs assessment. In supporting this project, the Federal Ministry aims to gain insight into efficient components of community prevention and health promotion networks as it is implemented and evaluated. The district will serve as a model region, so that successful components can be transferred to other regions throughout Germany. Accordingly, the transferability to other regions is of high interest in this project. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=childhood%20research" title="childhood research">childhood research</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20promotion" title=" health promotion"> health promotion</a>, <a href="https://publications.waset.org/abstracts/search?q=physical%20health" title=" physical health"> physical health</a>, <a href="https://publications.waset.org/abstracts/search?q=prevention%20network" title=" prevention network"> prevention network</a>, <a href="https://publications.waset.org/abstracts/search?q=psychological%20well-being" title=" psychological well-being"> psychological well-being</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20inclusion" title=" social inclusion"> social inclusion</a> </p> <a href="https://publications.waset.org/abstracts/55186/implementing-a-prevention-network-for-the-ortenaukreis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55186.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">222</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5</span> Persuading ICT Consumers to Disconnect from Work: An Experimental Study on the Influence of Message Frame, Regulatory Focus, Ad Believability and Attitude toward the Ad on Message Effectiveness</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Katharina%20Ninaus">Katharina Ninaus</a>, <a href="https://publications.waset.org/abstracts/search?q=Ralf%20Terlutter"> Ralf Terlutter</a>, <a href="https://publications.waset.org/abstracts/search?q=Sandra%20Diehl"> Sandra Diehl</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Information and communication technologies (ICT) have become pervasive in all areas of modern life, both in work and leisure. Technological developments and particularly the ubiquity of smartphones have made it possible for ICT consumers to be constantly connected to work, fostering an always-on mentality and increasing the pressure to be accessible at all times. However, performing work tasks outside of working hours using ICT results in a lack of mental detachment and recovery from work. It is, therefore, necessary to develop effective behavioral interventions to increase risk awareness of a constant connection to the workplace in the employed population. Drawing on regulatory focus theory, this study aims to investigate the persuasiveness of tailoring messages to individuals’ chronic regulatory focus in order to encourage ICT consumers to set boundaries by defining fixed times for professional accessibility outside of working hours in order to contribute to the well-being of ICT consumers with high ICT involvement in their work life. The experimental study examines the interaction effect between consumers’ chronic regulatory focus (i.e. promotion focus versus prevention focus) and positive or negative message framing (i.e. gain frame versus loss frame) on consumers’ intention to perform the advocated behavior. Based on the assumption that congruent messages create regulatory fit and increase message effectiveness, it is hypothesized that behavioral intention will be higher in the condition of regulatory fit compared to regulatory non-fit. It is further hypothesized that ad believability and attitude toward the ad will mediate the effect of regulatory fit on behavioral intention given that ad believability and ad attitude both determine consumer behavioral responses. Results confirm that the interaction between regulatory focus and message frame emerged as a predictor of behavioral intention such as that consumers’ intentions to set boundaries by defining fixed times for professional accessibility outside of working hours increased as congruency with their regulatory focus increased. The loss-framed ad was more effective for consumers with a predominant prevention focus, while the gain-framed ad was more effective for consumers with a predominant promotion focus. Ad believability and attitude toward the ad both emerged as predictors of behavioral intention. Mediation analysis revealed that the direct effect of the interaction between regulatory focus and message frame on behavioral intention was no longer significant when including ad believability and ad attitude as mediators in the model, indicating full mediation. However, while the indirect effect through ad believability was significant, the indirect effect through attitude toward the ad was not significant. Hence, regulatory fit increased ad believability, which then increased behavioral intention. Ad believability appears to have a superior effect indicating that behavioral intention does not depend on attitude toward the ad, but it depends on whether or not the ad is perceived as believable. The study shows that the principle of regulatory fit holds true in the context of ICT consumption and responds to calls for more research on mediators of health message framing effects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=always-on%20mentality" title="always-on mentality">always-on mentality</a>, <a href="https://publications.waset.org/abstracts/search?q=Information%20and%20communication%20technologies%20%28ICT%29%20consumption" title=" Information and communication technologies (ICT) consumption"> Information and communication technologies (ICT) consumption</a>, <a href="https://publications.waset.org/abstracts/search?q=message%20framing" title=" message framing"> message framing</a>, <a href="https://publications.waset.org/abstracts/search?q=regulatory%20focus" title=" regulatory focus"> regulatory focus</a> </p> <a href="https://publications.waset.org/abstracts/70435/persuading-ict-consumers-to-disconnect-from-work-an-experimental-study-on-the-influence-of-message-frame-regulatory-focus-ad-believability-and-attitude-toward-the-ad-on-message-effectiveness" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70435.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">210</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4</span> Assessing the Plant Diversity's Quality, Threats and Opportunities for the Support of Sustainable City Development of the City Raipur, India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Katharina%20Lapin">Katharina Lapin</a>, <a href="https://publications.waset.org/abstracts/search?q=Debashis%20Sanyal"> Debashis Sanyal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Worldwide urban areas are growing. Urbanization has a great impact on social and economic development and ecosystem services. This global trend of urbanization also has significant impact on habitat and biodiversity. The impact of urbanization on the biodiversity of cities in Europe and North America is well studied, while there is a lack of data from cities in currently fast growing urban areas. Indian cities are expanding. The scientific community and the governmental authorities are facing the ongoing urbanization process as an opportunity for the environment. This case study supports the evaluation of urban biodiversity of the city Raipur in the North-West of India. The aim of this study is to assess the overview of the environmental and ecological implications of urbanization. The collected data and analysis was used to discuss the challenges for the sustainable city development. Vascular plants were chosen as an appropriate indicator for the assessment of local biodiversity changes. On the one hand, the vegetation cover is sensible to anthropogenic influence, and in the other hand, the local species composition is comparable to changes at the regional and national scale, using the plant index of India. Further information of abiotic situation can be gathered with the determination of indicator species. In order to calculate the influence of urbanization on the native plant diversity, the Shannon diversity index H´ was chosen. The Pielou`s pooled quadrate method was used for estimating diversity when a random sample is not expected. It was used to calculate the Pilou´s index of evenness. The estimated species coverage was used for calculating the H´ and J. Pearson correlation was performed to test the relationship between urbanization pattern and plant diversity. Further, a SWOT analysis was used in for analyzing internal and external factors impinging on a decision making process. The city of Raipur (21.25°N 81.63°E) has a population of 1,010,087 inhabitants living in an urban area of 226km², in the district of the Indian state of Chhattisgarh. Within the last decade, the urban area of Raipur increased. The results show that various novel ecosystems exist in the urban area of Raipur. The high amount of native flora is mainly to find at the shore of urban lakes and along the river Karun. These areas of high Biodiversity Index are to protect as urban biodiversity hot spots. The governmental authorities are well informed about the environmental challenges for the sustainable development of the city. Together with the scientific community of the Technical University of Raipur many engineering solutions are discussed for implementation of the future. The case study helped to point out the importance environmental measures that support the ecosystem services of green infrastructure. The fast process of urbanization is difficult to control. Uncontrolled creation of urban housing leads to difficulties in unsustainable use of natural resources. This is the major threat for the urban biodiversity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=India" title="India">India</a>, <a href="https://publications.waset.org/abstracts/search?q=novel%20ecosystems" title=" novel ecosystems"> novel ecosystems</a>, <a href="https://publications.waset.org/abstracts/search?q=plant%20diversity" title=" plant diversity"> plant diversity</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20ecology" title=" urban ecology"> urban ecology</a> </p> <a href="https://publications.waset.org/abstracts/64883/assessing-the-plant-diversitys-quality-threats-and-opportunities-for-the-support-of-sustainable-city-development-of-the-city-raipur-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/64883.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">277</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3</span> Disposal Behavior of Extreme Poor People Living in Guatemala at the Base of the Pyramid</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Katharina%20Raab">Katharina Raab</a>, <a href="https://publications.waset.org/abstracts/search?q=Ralf%20Wagner"> Ralf Wagner</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With the decrease of poverty, the focus on the solid waste challenge shifts away from affluent, mostly Westernized consumers to the base of the pyramid. The relevance of considering the disposal behavior of impoverished people arises from improved welfare, leading to an increase in consumption opportunities and, consequently, of waste production. In combination with the world’s growing population the relevance of the topic increases, because solid waste management has global impacts on consumers’ welfare. The current annual municipal solid waste generation is estimated to 1.9 billion tonnes, 30% remains uncollected. As for the collected 70% is landfilling and dumping, 19% is recycled or recovered, 11% is led to energy recovery facilities. Therefore, aim is to contribute by adding first insights about poor people's disposal behaviors, including the framing of their rationalities, emotions and cognitions. The study provides novel empirical results obtained from qualitative semi-structured in-depth interviews near Guatemala City. In the study’s framework consumers have to choose from three options when deciding what to do with their obsolete possessions: Keeping the product: The main reason for this is the respondent´s emotional attachment to a product. Further, there is a willingness to use the same product under a different scope when it loses its functionality–they recycle their belongings in a customized and sustainable way. Permanently disposing of the product: The study reveals two dominant disposal methods: burning in front of their homes and throwing away in the physical environment. Respondents clearly recognized the disadvantages of burning toxic durables, like electronics. Giving a product away as a gift supports the integration of individuals in their peer networks of family and friends. Temporarily disposing of the product: Was not mentioned–to be specific, rent or lend a product to someone else was out of question. Contrasting the background to which extend poor people are aware of the consequences of their disposal decisions and how they feel about and rationalize their actions were quite unexpected. Respondents reported that they are worried about future consequences with impacts they cannot anticipate now–they are aware that their behaviors harm their health and the environment. Additionally, they expressed concern about the impact this disposal behavior would have on others’ well-being and are therefore sensitive to the waste that surrounds them. Concluding, the BoP-framed life and Westernized consumption, both fit in a circular economy pattern, but the nature of how to recycle and dispose separates these two societal groups. Both systems own a solid waste management system, but people living in slum-type districts and rural areas of poor countries are less interested in connecting to the system–they are primarily afraid of the costs. Further, it can be said that a consumer’s perceived effectiveness is distinct from environmental concerns, but contributes to forecasting certain pro-ecological behaviors. Considering the rationales underlying disposal decisions, thoughtfulness is a well-established determinant of disposition behavior. The precipitating events, emotions and decisions associated with the act of disposing of products are important because these decisions can trigger different results for the disposal process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=base%20of%20the%20pyramid" title="base of the pyramid">base of the pyramid</a>, <a href="https://publications.waset.org/abstracts/search?q=disposal%20behavior" title=" disposal behavior"> disposal behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=poor%20consumers" title=" poor consumers"> poor consumers</a>, <a href="https://publications.waset.org/abstracts/search?q=solid%20waste" title=" solid waste"> solid waste</a> </p> <a href="https://publications.waset.org/abstracts/78030/disposal-behavior-of-extreme-poor-people-living-in-guatemala-at-the-base-of-the-pyramid" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78030.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">171</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2</span> Defective Autophagy Disturbs Neural Migration and Network Activity in hiPSC-Derived Cockayne Syndrome B Disease Models</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Julia%20Kapr">Julia Kapr</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrea%20Rossi"> Andrea Rossi</a>, <a href="https://publications.waset.org/abstracts/search?q=Haribaskar%20Ramachandran"> Haribaskar Ramachandran</a>, <a href="https://publications.waset.org/abstracts/search?q=Marius%20Pollet"> Marius Pollet</a>, <a href="https://publications.waset.org/abstracts/search?q=Ilka%20Egger"> Ilka Egger</a>, <a href="https://publications.waset.org/abstracts/search?q=Selina%20Dangeleit"> Selina Dangeleit</a>, <a href="https://publications.waset.org/abstracts/search?q=Katharina%20Koch"> Katharina Koch</a>, <a href="https://publications.waset.org/abstracts/search?q=Jean%20Krutmann"> Jean Krutmann</a>, <a href="https://publications.waset.org/abstracts/search?q=Ellen%20Fritsche"> Ellen Fritsche</a> </p> <p class="card-text"><strong>Abstract:</strong></p> It is widely acknowledged that animal models do not always represent human disease. Especially human brain development is difficult to model in animals due to a variety of structural and functional species-specificities. This causes significant discrepancies between predicted and apparent drug efficacies in clinical trials and their subsequent failure. Emerging alternatives based on 3D in vitro approaches, such as human brain spheres or organoids, may in the future reduce and ultimately replace animal models. Here, we present a human induced pluripotent stem cell (hiPSC)-based 3D neural in a vitro disease model for the Cockayne Syndrome B (CSB). CSB is a rare hereditary disease and is accompanied by severe neurologic defects, such as microcephaly, ataxia and intellectual disability, with currently no treatment options. Therefore, the aim of this study is to investigate the molecular and cellular defects found in neural hiPSC-derived CSB models. Understanding the underlying pathology of CSB enables the development of treatment options. The two CSB models used in this study comprise a patient-derived hiPSC line and its isogenic control as well as a CSB-deficient cell line based on a healthy hiPSC line (IMR90-4) background thereby excluding genetic background-related effects. Neurally induced and differentiated brain sphere cultures were characterized via RNA Sequencing, western blot (WB), immunocytochemistry (ICC) and multielectrode arrays (MEAs). CSB-deficiency leads to an altered gene expression of markers for autophagy, focal adhesion and neural network formation. Cell migration was significantly reduced and electrical activity was significantly increased in the disease cell lines. These data hint that the cellular pathologies is possibly underlying CSB. By induction of autophagy, the migration phenotype could be partially rescued, suggesting a crucial role of disturbed autophagy in defective neural migration of the disease lines. Altered autophagy may also lead to inefficient mitophagy. Accordingly, disease cell lines were shown to have a lower mitochondrial base activity and a higher susceptibility to mitochondrial stress induced by rotenone. Since mitochondria play an important role in neurotransmitter cycling, we suggest that defective mitochondria may lead to altered electrical activity in the disease cell lines. Failure to clear the defective mitochondria by mitophagy and thus missing initiation cues for new mitochondrial production could potentiate this problem. With our data, we aim at establishing a disease adverse outcome pathway (AOP), thereby adding to the in-depth understanding of this multi-faced disorder and subsequently contributing to alternative drug development. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=autophagy" title="autophagy">autophagy</a>, <a href="https://publications.waset.org/abstracts/search?q=disease%20modeling" title=" disease modeling"> disease modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=in%20vitro" title=" in vitro"> in vitro</a>, <a href="https://publications.waset.org/abstracts/search?q=pluripotent%20stem%20cells" title=" pluripotent stem cells"> pluripotent stem cells</a> </p> <a href="https://publications.waset.org/abstracts/148194/defective-autophagy-disturbs-neural-migration-and-network-activity-in-hipsc-derived-cockayne-syndrome-b-disease-models" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148194.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">120</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> Multimodal Integration of EEG, fMRI and Positron Emission Tomography Data Using Principal Component Analysis for Prognosis in Coma Patients</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Denis%20Jordan">Denis Jordan</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Golkowski"> Daniel Golkowski</a>, <a href="https://publications.waset.org/abstracts/search?q=Mathias%20Lukas"> Mathias Lukas</a>, <a href="https://publications.waset.org/abstracts/search?q=Katharina%20Merz"> Katharina Merz</a>, <a href="https://publications.waset.org/abstracts/search?q=Caroline%20Mlynarcik"> Caroline Mlynarcik</a>, <a href="https://publications.waset.org/abstracts/search?q=Max%20Maurer"> Max Maurer</a>, <a href="https://publications.waset.org/abstracts/search?q=Valentin%20Riedl"> Valentin Riedl</a>, <a href="https://publications.waset.org/abstracts/search?q=Stefan%20Foerster"> Stefan Foerster</a>, <a href="https://publications.waset.org/abstracts/search?q=Eberhard%20F.%20Kochs"> Eberhard F.

The present study was aimed to provide prognosis in coma patients using markers from electroencephalogram (EEG), blood oxygen level dependent (BOLD) functional magnetic resonance imaging (fMRI) and [18F]-fluorodeoxyglucose (FDG) positron emission tomography (PET). Unsuperwised principal component analysis (PCA) was used for multimodal integration of markers. Methods: Approved by the local ethics committee of the Technical University of Munich (Germany) 20 patients (aged 18-89) with severe brain damage were acquired through intensive care units at the Klinikum rechts der Isar in Munich and at the Therapiezentrum Burgau (Germany). At the day of EEG/fMRI/PET measurement (date I) patients (<3.5 month in coma) were grouped in the minimal conscious state (MCS) or vegetative state (VS) on the basis of their clinical presentation (coma recovery scale-revised, CRS-R). Follow-up assessment (date II) was also based on CRS-R in a period of 8 to 24 month after date I. At date I, 63 channel EEG (Brain Products, Gilching, Germany) was recorded outside the scanner, and subsequently simultaneous FDG-PET/fMRI was acquired on an integrated Siemens Biograph mMR 3T scanner (Siemens Healthineers, Erlangen Germany). Power spectral densities, permutation entropy (PE) and symbolic transfer entropy (STE) were calculated in/between frontal, temporal, parietal and occipital EEG channels. PE and STE are based on symbolic time series analysis and were already introduced as robust markers separating wakefulness from unconsciousness in EEG during general anesthesia. While PE quantifies the regularity structure of the neighboring order of signal values (a surrogate of cortical information processing), STE reflects information transfer between two signals (a surrogate of directed connectivity in cortical networks). fMRI was carried out using SPM12 (Wellcome Trust Center for Neuroimaging, University of London, UK). Functional images were realigned, segmented, normalized and smoothed. PET was acquired for 45 minutes in list-mode. For absolute quantification of brain’s glucose consumption rate in FDG-PET, kinetic modelling was performed with Patlak’s plot method. BOLD signal intensity in fMRI and glucose uptake in PET was calculated in 8 distinct cortical areas. PCA was performed over all markers from EEG/fMRI/PET. Prognosis (persistent VS and deceased patients vs. recovery to MCS/awake from date I to date II) was evaluated using the area under the curve (AUC) including bootstrap confidence intervals (CI, *: p<0.05). Results: Prognosis was reliably indicated by the first component of PCA (AUC=0.99*, CI=0.92-1.00) showing a higher AUC when compared to the best single markers (EEG: AUC<0.96*, fMRI: AUC<0.86*, PET: AUC<0.60). CRS-R did not show prediction (AUC=0.51, CI=0.29-0.78). Conclusion: In a multimodal analysis of EEG/fMRI/PET in coma patients, PCA lead to a reliable prognosis. The impact of this result is evident, as clinical estimates of prognosis are inapt at time and could be supported by quantitative biomarkers from EEG, fMRI and PET. Due to the small sample size, further investigations are required, in particular allowing superwised learning instead of the basic approach of unsuperwised PCA. <p
