class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nicola%20Menga">Nicola Menga</a>, <a href="https://publications.waset.org/abstracts/search?q=Giuseppe%20Carbone"> Giuseppe Carbone</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Although contact mechanics has been widely focused on the study of contacts between half-space, it has been recently pointed out that in presence of finite thickness elastic layers the results of the contact problem show significant difference in terms of the main contact quantities (e.g. contact area, penetration, mean pressure, etc.). Actually, there exist a wide range of industrial application demanding for this kind of studies, such as seals leakage prediction or pressure-sensitive coatings for electrical applications. In this work, we focus on the contact between a rigid profile and an elastic layer of thickness h confined under two different configurations: rigid constrain and applied uniform pressure. The elastic problem at hand has been formalized following Green’s function method and then numerically solved by means of a matrix inversion. We study different contact conditions, both considering and neglecting adhesive interactions at the interface. This leads to different solution techniques: Adhesive contacts equilibrium solution is found, in term of contact area for given penetration, making stationary the total free energy of the system; whereas, adhesiveless contacts are addressed defining an equilibrium criterion, again on the contact area, relying on the fracture mechanics stress intensity factor KI. In particular, we make the KI vanish at the edges of the contact area, as peculiar for adhesiveless elastic contacts. The results are obtained in terms of contact area, penetration, and mean pressure for both adhesive and adhesiveless contact conditions. As expected, in the case of a uniform applied pressure the slab turns out much more compliant than the rigidly constrained one. Indeed, we have observed that the peak value of the contact pressure, for both the adhesive and adhesiveless condition, is much higher for the rigidly constrained configuration than in the case of applied uniform pressure. Furthermore, we observed that, for little contact area, both systems behave the same and the pull-off occurs at approximately the same contact area and mean contact pressure. This is an expected result since in this condition the ratio between the layers thickness and the contact area is very high and both layer configurations recover the half-space behavior where the pull-off occurrence is mainly controlled by the adhesive interactions, which are kept constant among the cases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=contact%20mechanics" title="contact mechanics">contact mechanics</a>, <a href="https://publications.waset.org/abstracts/search?q=adhesion" title=" adhesion"> adhesion</a>, <a href="https://publications.waset.org/abstracts/search?q=friction" title=" friction"> friction</a>, <a href="https://publications.waset.org/abstracts/search?q=thick%20layer" title=" thick layer"> thick layer</a> </p> <a href="https://publications.waset.org/abstracts/24479/the-contact-between-a-rigid-substrate-and-a-thick-elastic-layer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24479.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">509</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">45</span> Optics Meets Microfluidics for Highly Sensitive Force Sensing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Iliya%20Dimitrov%20Stoev">Iliya Dimitrov Stoev</a>, <a href="https://publications.waset.org/abstracts/search?q=Benjamin%20Seelbinder"> Benjamin Seelbinder</a>, <a href="https://publications.waset.org/abstracts/search?q=Elena%20Erben"> Elena Erben</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicola%20Maghelli"> Nicola Maghelli</a>, <a href="https://publications.waset.org/abstracts/search?q=Moritz%20Kreysing"> Moritz Kreysing</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Despite the revolutionizing impact of optical tweezers in materials science and cell biology up to the present date, trapping has so far extensively relied on specific material properties of the probe and local heating has limited applications related to investigating dynamic processes within living systems.

However, such statistics seem incongruent with indigenous paradigms of unity, care, and connection. The inability of policymakers and mainstream service providers to acknowledge the direct links between the social contexts created by colonisation for indigenous families in Aotearoa and intergenerational FCSA has meant there has been little meaningful success in combatting this significant social problem. This research traces the conditions of intergenerational FCSA to the systemic inequalities created by colonization. Kaupapa Māori methodologies were applied to this qualitative piece of empirical research wherein 17 indigenous contributors shared their stories of FCSA. From these stories and existing literature, we can identify how the machinations of colonisation are mirrored by techniques used to perpetrate abuse. Once identified, we are then able to recommend actions for halting FCSA for future generations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=indigenity" title="indigenity">indigenity</a>, <a href="https://publications.waset.org/abstracts/search?q=family%20violence" title=" family violence"> family violence</a>, <a href="https://publications.waset.org/abstracts/search?q=childhood%20sexual%20abuse" title=" childhood sexual abuse"> childhood sexual abuse</a>, <a href="https://publications.waset.org/abstracts/search?q=colonization" title=" colonization"> colonization</a> </p> <a href="https://publications.waset.org/abstracts/161338/unforeseen-inequity-childhood-sexual-abuse-in-aotearoa-new-zealand" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161338.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">123</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">42</span> Polysulfide as Active ‘Stealth’ Polymers with Additional Anti-Inflammatory Activity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Farah%20El%20Mohtadi">Farah El Mohtadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Richard%20d%27Arcy"> Richard d'Arcy</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicola%20Tirelli"> Nicola Tirelli</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Since 40 years, poly (ethylene glycol) (PEG) has been the gold standard in biomaterials and drug delivery, because of its combination of chemical and biological inertness. However, the possibility of its breakdown under oxidative conditions and the demonstrated development of anti-PEG antibodies highlight the necessity to develop carriers based on materials with increased stability in a challenging biological environment. Here, we describe the synthesis of polysulfide via anionic ring-opening polymerization. In vitro, the synthesized polymer was characterized by low toxicity and a level of complement activation (in human plasma) and macrophage uptake slightly lower than PEG and poly (2‐methyl-2‐oxazoline) (PMOX), of a similar size. Importantly, and differently from PEG, on activated macrophages, the synthesized polymer showed a strong and dose-dependent ROS scavenging activity, which resulted in the corresponding reduction of cytokine production. Therefore, the results from these studies show that polysulfide is highly biocompatible and are potential candidates to be used as an alternative to PEG for various applications in nanomedicine. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=PEG" title="PEG">PEG</a>, <a href="https://publications.waset.org/abstracts/search?q=low%20toxicity" title=" low toxicity"> low toxicity</a>, <a href="https://publications.waset.org/abstracts/search?q=ROS%20scavenging" title=" ROS scavenging"> ROS scavenging</a>, <a href="https://publications.waset.org/abstracts/search?q=biocompatible" title=" biocompatible"> biocompatible</a> </p> <a href="https://publications.waset.org/abstracts/113114/polysulfide-as-active-stealth-polymers-with-additional-anti-inflammatory-activity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/113114.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">129</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">41</span> Tourism Qualification and Academics' Opinions about the Influence of Employability Skills on Graduates' Ability to Secure Jobs in the Tourism Industry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nicola%20Wakelin-Theron">Nicola Wakelin-Theron</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study focuses on higher education institutions in South Africa, with the view to understanding how tourism as a study discipline has evolved over the years, as well as the influence of employability skills on graduates’ ability to secure jobs in the tourism industry. Indeed, the employability landscape is becoming more complex; hence, it is imperative for higher education institutions to equip students with employability skills while going through their academic programmes and during their transition from higher education to the world of work. Employability – which is regarded as an empowerment mechanism and a key to job security – is a set of achievements which increases the probability for graduates to find and maintain employment. A quantitative research method was used to obtain the necessary information. Data were collected through a web-based, online survey questionnaire directed to academics from various public higher education institutions in South Africa that offer tourism as a qualification. The key findings revealed that academics are of the opinion that there are 5 skills that are influential in obtaining a position within the tourism industry. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=employability" title="employability">employability</a>, <a href="https://publications.waset.org/abstracts/search?q=industry%20skills" title=" industry skills"> industry skills</a>, <a href="https://publications.waset.org/abstracts/search?q=tourism%20industry" title=" tourism industry"> tourism industry</a>, <a href="https://publications.waset.org/abstracts/search?q=tourism%20qualification" title=" tourism qualification"> tourism qualification</a> </p> <a href="https://publications.waset.org/abstracts/54400/tourism-qualification-and-academics-opinions-about-the-influence-of-employability-skills-on-graduates-ability-to-secure-jobs-in-the-tourism-industry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54400.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">412</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">40</span> Assessment of the High-Speed Ice Friction of Bob Skeleton Runners</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Agata%20Tomaszewska">Agata Tomaszewska</a>, <a href="https://publications.waset.org/abstracts/search?q=Timothy%20Kamps"> Timothy Kamps</a>, <a href="https://publications.waset.org/abstracts/search?q=Stephan%20R.%20Turnock"> Stephan R.

It is believed that the friction between the runners and ice significantly contributes to the amount of the total energy loss during a bob skeleton descent. There is only limited available experimental data regarding the friction of bob skeleton runners or indeed steel on the ice at high sliding speeds ( > 20 m/s). Testing methods used to investigate the friction of steel on ice in winter sports have been outlined, and their accuracy and repeatability discussed. A system thinking approach was used to investigate the runner-ice interaction during sliding and create concept designs of three ice tribometers. The operational envelope of the bob skeleton system has been defined through mathematical modelling. Designs of a drum, linear and inertia pin-on-disk tribometers were developed specifically for bob skeleton runner testing with the requirement of reaching up to 40 m/s speed and facilitate fresh ice sliding. The design constraints have been outline and the proposed solutions compared based on the ease of operation, accuracy and the development cost. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bob%20skeleton" title="bob skeleton">bob skeleton</a>, <a href="https://publications.waset.org/abstracts/search?q=ice%20friction" title=" ice friction"> ice friction</a>, <a href="https://publications.waset.org/abstracts/search?q=high-speed%20tribometers" title=" high-speed tribometers"> high-speed tribometers</a>, <a href="https://publications.waset.org/abstracts/search?q=sliding%20friction" title=" sliding friction"> sliding friction</a> </p> <a href="https://publications.waset.org/abstracts/72268/assessment-of-the-high-speed-ice-friction-of-bob-skeleton-runners" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72268.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">261</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">39</span> Splenic Artery Aneurysms: A Rare, Insidious Cause of Abdominal Pain</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Christopher%20Oyediran">Christopher Oyediran</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicola%20Ubayasiri"> Nicola Ubayasiri</a>, <a href="https://publications.waset.org/abstracts/search?q=Christopher%20Gough"> Christopher Gough</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Splenic artery aneurysms are often clinically occult, occasionally identified incidentally with imaging.

We present a case of a 36-year-old female with a history of endometriosis and multiple sclerosis who presented to the Emergency Department with sudden onset epigastric pain and collapse. On arrival, she was pale and clammy with profound tachycardia and hypotension. An ultrasound done in the resuscitation department revealed abdominal free fluid. She was resuscitated with blood and transferred for emergent laparotomy. Laparotomy revealed massive haemoperitoneum from the spleen. She underwent emergency splenectomy and inspection of the spleen revealed a splenic artery aneurysm.

J. Laws-Nicola</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Henry Russell was best known as a composer of more than 300 songs. Many of his compositions were popular for both their sentimental texts, as in ‘The Old Armchair,’ and those of a more political nature, such as ‘Woodsman, Spare That Tree!’ Indeed, Russell had written such songs of advocacy as those associated with abolitionism (‘The Slave Ship’) and environmentalism (‘Woodsman, Spare that Tree!’). ‘The Maniac’ is his only composition addressing the issue of institutionalization. The text is borrowed and adapted from the monodrama The Captive by M.G. ‘Monk’ Lewis. Through an analysis of form, harmony, melody, text, and thematic development and interactions between text and music we can approach a clearer understanding of ‘The Maniac’ and how the text and music interact. Select periodicals, such as The London Times, provide contemporary critical review for ‘The Maniac.’ Additional nineteenth century songs whose texts focus on madness and/or institutionalization will assist in building a stylistic and cultural context for ‘The Maniac.’ Through comparative analyses of ‘The Maniac’ with a body of songs that focus on similar topics, we can approach a clear understanding of the song as a vehicle for deinstitutionalization. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=19th%20century%20song" title="19th century song">19th century song</a>, <a href="https://publications.waset.org/abstracts/search?q=institutionalization" title=" institutionalization"> institutionalization</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20G.%20Lewis" title=" M.

Menga</a>, <a href="https://publications.waset.org/abstracts/search?q=S.%20Hernandez"> S. Hernandez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Finite Element Models (FEMs) are widely used in order to study and predict the dynamic properties of structures and usually, the prediction can be obtained with much more accuracy in the case of a single component than in the case of assemblies. Especially for structural dynamics studies, in the low and middle frequency range, most complex FEMs can be seen as assemblies made by linear components joined together at interfaces. From a modelling and computational point of view, these types of joints can be seen as localized sources of stiffness and damping and can be modelled as lumped spring/damper elements, most of time, characterized by nonlinear constitutive laws. On the other side, most of FE programs are able to run nonlinear analysis in time-domain. They treat the whole structure as nonlinear, even if there is one nonlinear degree of freedom (DOF) out of thousands of linear ones, making the analysis unnecessarily expensive from a computational point of view. In this work, a methodology in order to obtain the nonlinear frequency response of structures, whose nonlinearities can be considered as localized sources, is presented. The work extends the well-known Structural Dynamic Modification Method (SDMM) to a nonlinear set of modifications, and allows getting the Nonlinear Frequency Response Functions (NLFRFs), through an ‘updating’ process of the Linear Frequency Response Functions (LFRFs). A brief summary of the analytical concepts is given, starting from the linear formulation and understanding what the implications of the nonlinear one, are. The response of the system is formulated in both: time and frequency domain. First the Modal Database is extracted and the linear response is calculated. Secondly the nonlinear response is obtained thru the NL SDMM, by updating the underlying linear behavior of the system. The methodology, implemented in MATLAB, has been successfully applied to estimate the nonlinear frequency response of two systems. The first one is a two DOFs spring-mass-damper system, and the second example takes into account a full aircraft FE Model. In spite of the different levels of complexity, both examples show the reliability and effectiveness of the method. The results highlight a feasible and robust procedure, which allows a quick estimation of the effect of localized nonlinearities on the dynamic behavior. The method is particularly powerful when most of the FE Model can be considered as acting linearly and the nonlinear behavior is restricted to few degrees of freedom. The procedure is very attractive from a computational point of view because the FEM needs to be run just once, which allows faster nonlinear sensitivity analysis and easier implementation of optimization procedures for the calibration of nonlinear models. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=frequency%20response" title="frequency response">frequency response</a>, <a href="https://publications.waset.org/abstracts/search?q=nonlinear%20dynamics" title=" nonlinear dynamics"> nonlinear dynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20dynamic%20modification" title=" structural dynamic modification"> structural dynamic modification</a>, <a href="https://publications.waset.org/abstracts/search?q=softening%20effect" title=" softening effect"> softening effect</a>, <a href="https://publications.waset.org/abstracts/search?q=rubber" title=" rubber"> rubber</a> </p> <a href="https://publications.waset.org/abstracts/47202/frequency-response-of-complex-systems-with-localized-nonlinearities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47202.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">266</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">36</span> Optimization of Bio-Based Lightweight Mortars Containing Wood Waste</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Valeria%20Corinaldesi">Valeria Corinaldesi</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicola%20Generosi"> Nicola Generosi</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniele%20Berdini"> Daniele Berdini</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, wood waste from processing by-products was used by replacing natural sand for producing bio-based lightweight mortars. Manufacturers of wood products and furniture usually generate sawdust and pieces of side-cuts. These are produced by cutting, drilling, and milling operations as well. Three different percentages of substitution of quartz sand were tried: 2.5%, 5%, and 10% by volume. Wood by-products were pre-soaked in calcium hydroxide aqueous solution in order to obtain wood mineralization to avoid undesirable effects on the bio-based building materials. Bio-based mortars were characterized by means of compression and bending tests, free drying shrinkage tests, resistance to water vapour permeability, water capillary absorption, and, finally, thermal conductivity measurements. Results obtained showed that a maximum dosage of 5% wood by-products should be used in order to avoid an excessive loss of bio-based mortar mechanical strength. On the other hand, by adding the proper dosage of water-reducing admixture, adequate mechanical performance can be achieved even with 10% wood waste addition. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bio-based%20mortar" title="bio-based mortar">bio-based mortar</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20efficiency" title=" energy efficiency"> energy efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=lightweight%20mortar" title=" lightweight mortar"> lightweight mortar</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20insulation" title=" thermal insulation"> thermal insulation</a>, <a href="https://publications.waset.org/abstracts/search?q=wood%20waste" title=" wood waste"> wood waste</a> </p> <a href="https://publications.waset.org/abstracts/194886/optimization-of-bio-based-lightweight-mortars-containing-wood-waste" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/194886.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">4</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">35</span> Humanising Digital Healthcare to Build Capacity by Harnessing the Power of Patient Data</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Durhane%20Wong-Rieger">Durhane Wong-Rieger</a>, <a href="https://publications.waset.org/abstracts/search?q=Kawaldip%20Sehmi"> Kawaldip Sehmi</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicola%20Bedlington"> Nicola Bedlington</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicole%20Boice"> Nicole Boice</a>, <a href="https://publications.waset.org/abstracts/search?q=Tam%C3%A1s%20Bereczky"> Tamás Bereczky</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Patient-generated health data should be seen as the expression of the experience of patients, including the outcomes reflecting the impact a treatment or service had on their physical health and wellness. We discuss how the healthcare system can reach a place where digital is a determinant of health - where data is generated by patients and is respected and which acknowledges their contribution to science. We explore the biggest barriers facing this. The International Experience Exchange with Patient Organisation’s Position Paper is based on a global patient survey conducted in Q3 2021 that received 304 responses. Results were discussed and validated by the 15 patient experts and supplemented with literature research. Results are a subset of this. Our research showed patient communities want to influence how their data is generated, shared, and used. Our study concludes that a reasonable framework is needed to protect the integrity of patient data and minimise abuse, and build trust. Results also demonstrated a need for patient communities to have more influence and control over how health data is generated, shared, and used. The results clearly highlight that the community feels there is a lack of clear policies on sharing data. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=digital%20health" title="digital health">digital health</a>, <a href="https://publications.waset.org/abstracts/search?q=equitable%20access" title=" equitable access"> equitable access</a>, <a href="https://publications.waset.org/abstracts/search?q=humanise%20healthcare" title=" humanise healthcare"> humanise healthcare</a>, <a href="https://publications.waset.org/abstracts/search?q=patient%20data" title=" patient data"> patient data</a> </p> <a href="https://publications.waset.org/abstracts/155216/humanising-digital-healthcare-to-build-capacity-by-harnessing-the-power-of-patient-data" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155216.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">82</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">34</span> Financial Centers and BRICS Stock Markets: The Effect of the Recent Crises</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marco%20Barassi">Marco Barassi</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicola%20Spagnolo"> Nicola Spagnolo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper uses a DCC-GARCH model framework to examine mean and volatility spillovers (i.e. causality in mean and variance) dynamics between financial centers and the stock market indexes of the BRICS countries. In addition, tests for changes in the transmission mechanism are carried out by first testing for structural breaks and then setting a dummy variable to control for the 2008 financial crises. We use weekly data for nine countries, four financial centers (Germany, Japan, UK and USA) and the five BRICS countries (Brazil, Russia, India, China and South Africa). Furthermore, we control for monetary policy using domestic interest rates (90-day Treasury Bill interest rate) over the period 03/1/1990 - 04/2/2014, for a total of 1204 observations. Results show that the 2008 financial crises changed the causality dynamics for most of the countries considered. The same pattern can also be observed in conditional correlation showing a shift upward following the turbulence associated to the 2008 crises. The magnitude of these effects suggests a leading role played by the financial centers in effecting Brazil and South Africa, whereas Russia, India and China show a higher degree of resilience. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=financial%20crises" title="financial crises">financial crises</a>, <a href="https://publications.waset.org/abstracts/search?q=DCC-GARCH%20model" title=" DCC-GARCH model"> DCC-GARCH model</a>, <a href="https://publications.waset.org/abstracts/search?q=volatility%20spillovers" title=" volatility spillovers"> volatility spillovers</a>, <a href="https://publications.waset.org/abstracts/search?q=economics" title=" economics"> economics</a> </p> <a href="https://publications.waset.org/abstracts/8104/financial-centers-and-brics-stock-markets-the-effect-of-the-recent-crises" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8104.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">33</span> Meticulous Doxorubicin Release from pH-Responsive Nanoparticles Entrapped within an Injectable Thermoresponsive Depot </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Huayang%20Yu">Huayang Yu</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicola%20Ingram"> Nicola Ingram</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20C.%20Green"> David C.

Non-cytotoxic polymer nanoparticles are formed from poly(ethylene glycol)-b-poly(benzyl glutamate) that, uniquely, contain a central ester link. This connection renders the nanoparticles pH-responsive, enabling extensive doxorubicin release in acidic solutions (pH 6.5), but not in solutions of physiological pH (pH 7.4). Doxorubicin loaded nanoparticles were found to be stable for at least 31 days and lethal against the three breast cancer cell lines tested. Furthermore, doxorubicin-loaded nanoparticles could be incorporated within a thermoresponsive poly(2-hydroxypropyl methacrylate) gel depot, which forms immediately upon injection of poly(2-hydroxypropyl methacrylate) into aqueous solution. The combination of the poly(2-hydroxypropyl methacrylate) gel and poly(ethylene glycol)-b-poly(benzyl glutamate) nanoparticles yields an injectable doxorubicin delivery system that facilities near-complete drug release when maintained at elevated temperatures (37 °C) in acidic solution (pH 6.5). In contrast, negligible payload release occurs when the material is stored at room temperature in a non-acidic solution (pH 7.4). The system has great potential as a vehicle for the prolonged, site-specific release of chemotherapeutics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biodegradable" title="biodegradable">biodegradable</a>, <a href="https://publications.waset.org/abstracts/search?q=nanoparticle" title=" nanoparticle"> nanoparticle</a>, <a href="https://publications.waset.org/abstracts/search?q=polymer" title=" polymer"> polymer</a>, <a href="https://publications.waset.org/abstracts/search?q=thermoresponsive" title=" thermoresponsive"> thermoresponsive</a> </p> <a href="https://publications.waset.org/abstracts/123917/meticulous-doxorubicin-release-from-ph-responsive-nanoparticles-entrapped-within-an-injectable-thermoresponsive-depot" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/123917.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">136</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">32</span> The Osteocutaneous Distal Tibia Turn-over Fillet Flap: A Novel Spare-parts Orthoplastic Surgery Option for Functional Below-knee Amputation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Harry%20Burton">Harry Burton</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexios%20Dimitrios%20Iliadis"> Alexios Dimitrios Iliadis</a>, <a href="https://publications.waset.org/abstracts/search?q=Neil%20Jones"> Neil Jones</a>, <a href="https://publications.waset.org/abstracts/search?q=Aaron%20Saini"> Aaron Saini</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicola%20Bystrzonowski"> Nicola Bystrzonowski</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexandros%20Vris"> Alexandros Vris</a>, <a href="https://publications.waset.org/abstracts/search?q=Georgios%20Pafitanis"> Georgios Pafitanis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This article portrays the authors’ experience with a complex lower limb bone and soft tissue defect, following chronic osteomyelitis and pathological fracture, which was managed by the multidisciplinary orthoplastic team. The decision for functional amputation versus limb salvage was deemed necessary, enhanced by the principles of “spares parts” in reconstructive microsurgery. This case describes a successful use of the osteocutaneous distal tibia turn-over fillet flap that allowed ‘lowering the level of the amputation’ from a through knee to the conventional level of a below-knee amputation to preserve the knee joint function. This case demonstrates the value of ‘spare-parts’ surgery principles and how these concepts refine complex orthoplastic approaches when limb salvage is not possible to enhance function. The osteocutaneous distal tibia turn-over fillet flap is a robust technique for modified BKA reconstructions that provides sufficient bone length to achieve a tough, sensate stump and functional knee joint. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=osteocutaneous%20flap" title="osteocutaneous flap">osteocutaneous flap</a>, <a href="https://publications.waset.org/abstracts/search?q=fillet%20flap" title=" fillet flap"> fillet flap</a>, <a href="https://publications.waset.org/abstracts/search?q=spare-parts%20surgery" title=" spare-parts surgery"> spare-parts surgery</a>, <a href="https://publications.waset.org/abstracts/search?q=Below%20knee%20amputation" title=" Below knee amputation"> Below knee amputation</a> </p> <a href="https://publications.waset.org/abstracts/146660/the-osteocutaneous-distal-tibia-turn-over-fillet-flap-a-novel-spare-parts-orthoplastic-surgery-option-for-functional-below-knee-amputation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146660.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">166</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">31</span> Mechanical Characterization and Durability of Eco-Efficient Ultra High Performance Concrete</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Valeria%20Corinaldesi">Valeria Corinaldesi</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicola%20Generosi"> Nicola Generosi</a>, <a href="https://publications.waset.org/abstracts/search?q=Jacopo%20Donnini"> Jacopo Donnini</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ultra high performance concrete (UHPC) is an innovative material which tends to exhibit superior properties such as incredible mechanical and durability performance and non-brittleness behavior. Over the last twenty years, phenomenal advances have taken place in the research and application of UHPC. Recently, the approach is to improve UHPC sustainability by reducing its embodied energy. First of all, this goal can be achieved by reducing Portland cement dosage. In this work, an experimental investigation was carried out to characterize the mechanical behavior and durability of UHPCs prepared by reducing the cement amount by 30% in order to verify the impact of lower cement content and higher water-to-cement ratio on both mechanical performance and durability, if any. Eight different UHPC mixtures were compared, with two different cement dosages (either 1000 or 700 kg) and four different brass-coated steel fibres dosages (0 - 50 - 100 - 150 kg), in terms of 28-day compressive and flexural strengths. Then, the mixtures prepared with the lower cement content were further investigated in terms of abrasion resistance, water absorption, freezing and thawing cycles, and resistance to sulphate attack. Results obtained showed the feasibility of reducing cement dosage without compromising mechanical performance and UHPC's extraordinary durability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=abrasion%20resistance" title="abrasion resistance">abrasion resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=durability" title=" durability"> durability</a>, <a href="https://publications.waset.org/abstracts/search?q=eco-efficiency" title=" eco-efficiency"> eco-efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=freeze-thawing%20cycles" title=" freeze-thawing cycles"> freeze-thawing cycles</a>, <a href="https://publications.waset.org/abstracts/search?q=steel%20fibres" title=" steel fibres"> steel fibres</a>, <a href="https://publications.waset.org/abstracts/search?q=sulphate%20exposure" title=" sulphate exposure"> sulphate exposure</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=UHPC" title=" UHPC"> UHPC</a> </p> <a href="https://publications.waset.org/abstracts/163828/mechanical-characterization-and-durability-of-eco-efficient-ultra-high-performance-concrete" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163828.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">75</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">30</span> Analysis of the Effects of Vibrations on Tractor Drivers by Measurements With Wearable Sensors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gubiani%20Rino">Gubiani Rino</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicola%20Zucchiatti"> Nicola Zucchiatti</a>, <a href="https://publications.waset.org/abstracts/search?q=Da%20Broi%20Ugo"> Da Broi Ugo</a>, <a href="https://publications.waset.org/abstracts/search?q=Bietresato%20Marco"> Bietresato Marco</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The problem of vibrations in agriculture is very important due to the different types of machinery used for the different types of soil in which work is carried out. One of the most commonly used machines is the tractor, where the phenomenon has been studied for a long time by measuring the whole body and placing the sensor on the seat. However, this measurement system does not take into account the characteristics of the drivers, such as their body index (BMI), their gender (male, female) or the muscle fatigue they are subjected to, which is highly dependent on their age for example. The aim of the research was therefore to place sensors not only on the seat but along the spinal column to check the transmission of vibration on drivers with different BMI on different tractors and at different travel speeds and of different genders. The test was also done using wearable sensors such as a dynamometer applied to the muscles, the data of which was correlated with the vibrations produced by the tractor. Initial data show that even on new tractors with pneumatic seats, the vibrations attenuate little and are still correlated with the roughness of the track travelled and the forward speed. Another important piece of data are the root-mean square values referred to 8 hours (A(8)x,y,z) and the maximum transient vibration values (MTVVx,y,z) and, the latter, the MTVVz values were problematic (limiting factor in most cases) and always aggravated by the speed. The MTVVx values can be lowered by having a tyre-pressure adjustment system, able to properly adjust the tire pressure according to the specific situation (ground, speed) in which a tractor is operating. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fatigue" title="fatigue">fatigue</a>, <a href="https://publications.waset.org/abstracts/search?q=effect%20vibration%20on%20health" title=" effect vibration on health"> effect vibration on health</a>, <a href="https://publications.waset.org/abstracts/search?q=tractor%20driver%20vibrations" title=" tractor driver vibrations"> tractor driver vibrations</a>, <a href="https://publications.waset.org/abstracts/search?q=vibration" title=" vibration"> vibration</a>, <a href="https://publications.waset.org/abstracts/search?q=muscle%20skeleton%20disorders" title=" muscle skeleton disorders"> muscle skeleton disorders</a> </p> <a href="https://publications.waset.org/abstracts/174066/analysis-of-the-effects-of-vibrations-on-tractor-drivers-by-measurements-with-wearable-sensors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/174066.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">70</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> Diagnostic Accuracy Of Core Biopsy In Patients Presenting With Axillary Lymphadenopathy And Suspected Non-Breast Malignancy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Monisha%20Edirisooriya">Monisha Edirisooriya</a>, <a href="https://publications.waset.org/abstracts/search?q=Wilma%20Jack"> Wilma Jack</a>, <a href="https://publications.waset.org/abstracts/search?q=Dominique%20Twelves">Dominique Twelves</a>, <a href="https://publications.waset.org/abstracts/search?q=Jennifer%20Royds"> Jennifer Royds</a>, <a href="https://publications.waset.org/abstracts/search?q=Fiona%20Scott"> Fiona Scott</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicola%20Mason"> Nicola Mason</a>, <a href="https://publications.waset.org/abstracts/search?q=Arran%20Turnbull"> Arran Turnbull</a>, <a href="https://publications.waset.org/abstracts/search?q=J.%20Michael%20Dixon"> J.

Core biopsy of nodes can provide sufficient tissue for diagnosis and has advantages in terms of morbidity and speed of diagnosis. This study evaluates the diagnostic accuracy of core biopsy in patients presenting with axillary lymphadenopathy. Methods: Between 2009 and 2019, 165 patients referred to the Edinburgh Breast Unit had a total of 179 axillary lymph node core biopsies. Results: 152 (92%) of the 165 initial core biopsies were deemed to contain adequate nodal tissue. Core biopsy correctly established malignancy in 75 of the 78 patients with haematological malignancy (96%) and in all 28 patients with metastatic carcinoma (100%) and correctly diagnosed benign changes in 49 of 57 (86%) patients with benign conditions. There were no false positives and no false negatives. In 67 (85.9%) of the 78 patients with hematological malignancy, there was sufficient material in the first core biopsy to allow the pathologist to make an actionable diagnosis and not ask for more tissue sampling prior to treatment. There were no complications of core biopsy. On follow up, none of the patients with benign cores has been shown to have malignancy in the axilla and none with lymphoma had their initial disease incorrectly classified. Conclusions: This study shows that core biopsy is now the investigation of choice for patients presenting with axillary lymphadenopathy even in those suspected as having lymphoma. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=core%20biopsy" title="core biopsy">core biopsy</a>, <a href="https://publications.waset.org/abstracts/search?q=excision%20biopsy" title=" excision biopsy"> excision biopsy</a>, <a href="https://publications.waset.org/abstracts/search?q=axillary%20lymphadenopathy" title=" axillary lymphadenopathy"> axillary lymphadenopathy</a>, <a href="https://publications.waset.org/abstracts/search?q=non-breast%20malignancy" title=" non-breast malignancy"> non-breast malignancy</a> </p> <a href="https://publications.waset.org/abstracts/141187/diagnostic-accuracy-of-core-biopsy-in-patients-presenting-with-axillary-lymphadenopathy-and-suspected-non-breast-malignancy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141187.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">241</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">28</span> Museums and Corporate Social Responsibility: Environmental Impact and Strategies in Corporate Social Responsibility Policies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nicola%20Urbino">Nicola Urbino</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The definition of corporate social responsibility policies is a central topic in contemporary museology, as the role of museums in developing social, cultural, and environmental impact strategies has become increasingly prominent. An overarching perspective in this domain can be provided by the publication of the primary tool for impact verification and reporting in the CSR field: the Social Report. The presentation, based on an international and national theoretical and regulatory assessment, focuses on the operational significance of structured social reporting for Italian museums. The study involves analyzing over 25 Social Reports from leading Italian museums over the past 5 years to assess their CSR practices, examining both the strengths and weaknesses, in order to offer a comprehensive overview of the phenomenon of social responsibility in the national context. Moreover, a benchmark will be done between the legislative framework and guidelines and the effective implementation of CSR policies and practices. That said, the contribution aims at analyzing the strategies of the main Italian museums regarding their environmental impact on the territory. Through the analysis of the Social Balance Sheets published by a group of museums from the north to the south of Italy, it will highlight the relations that museums have established over the years with the territory and the environment, their sensitivity to climate change, and the strategies proposed to mitigate their environmental impact. Starting from a general analysis, the paper will help to highlight best practices and management models to be followed for sustainable growth, analyzing best practice, case studies and strategies applied to the museological field. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=museums" title="museums">museums</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20report" title=" social report"> social report</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20development" title=" sustainable development"> sustainable development</a>, <a href="https://publications.waset.org/abstracts/search?q=footprint" title=" footprint"> footprint</a> </p> <a href="https://publications.waset.org/abstracts/190795/museums-and-corporate-social-responsibility-environmental-impact-and-strategies-in-corporate-social-responsibility-policies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/190795.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">27</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> In and Out-Of-Sample Performance of Non Simmetric Models in International Price Differential Forecasting in a Commodity Country Framework</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nicola%20Rubino">Nicola Rubino</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents an analysis of a group of commodity exporting countries' nominal exchange rate movements in relationship to the US dollar. Using a series of Unrestricted Self-exciting Threshold Autoregressive models (SETAR), we model and evaluate sixteen national CPI price differentials relative to the US dollar CPI. Out-of-sample forecast accuracy is evaluated through calculation of mean absolute error measures on the basis of two-hundred and fifty-three months rolling window forecasts and extended to three additional models, namely a logistic smooth transition regression (LSTAR), an additive non linear autoregressive model (AAR) and a simple linear Neural Network model (NNET). Our preliminary results confirm presence of some form of TAR non linearity in the majority of the countries analyzed, with a relatively higher goodness of fit, with respect to the linear AR(1) benchmark, in five countries out of sixteen considered. Although no model appears to statistically prevail over the other, our final out-of-sample forecast exercise shows that SETAR models tend to have quite poor relative forecasting performance, especially when compared to alternative non-linear specifications. Finally, by analyzing the implied half-lives of the > coefficients, our results confirms the presence, in the spirit of arbitrage band adjustment, of band convergence with an inner unit root behaviour in five of the sixteen countries analyzed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=transition%20regression%20model" title="transition regression model">transition regression model</a>, <a href="https://publications.waset.org/abstracts/search?q=real%20exchange%20rate" title=" real exchange rate"> real exchange rate</a>, <a href="https://publications.waset.org/abstracts/search?q=nonlinearities" title=" nonlinearities"> nonlinearities</a>, <a href="https://publications.waset.org/abstracts/search?q=price%20differentials" title=" price differentials"> price differentials</a>, <a href="https://publications.waset.org/abstracts/search?q=PPP" title=" PPP"> PPP</a>, <a href="https://publications.waset.org/abstracts/search?q=commodity%20points" title=" commodity points"> commodity points</a> </p> <a href="https://publications.waset.org/abstracts/75704/in-and-out-of-sample-performance-of-non-simmetric-models-in-international-price-differential-forecasting-in-a-commodity-country-framework" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75704.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">278</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> The Interactions of Attentional Bias for Food, Trait Self-Control, and Motivation: A Model Testing Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamish%20Love">Hamish Love</a>, <a href="https://publications.waset.org/abstracts/search?q=Navjot%20Bhullar"> Navjot Bhullar</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicola%20Schutte"> Nicola Schutte</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Self-control and related psychological constructs have been shown to have a large role in the improvement and maintenance of healthful dietary behaviour. However, self-control for diet, and related constructs such as motivation, level of conflict between tempting desires and dietary goals, and attentional bias for tempting food, have not been studied together to establish their relationships, to the author’s best knowledge. Therefore the aim of this paper was to conduct model testing on these constructs and evaluate how they relate to affect dietary outcomes. 400 Australian adult participants will be recruited via the Qualtrics platform and will be representative across age and gender. They will complete survey and reaction timing surveys to gather data on the five target constructs: Trait Self-control, Attentional Bias for Food, Dietary Goal-Desire Incongruence, Motivation for Dietary Self-control, and Satisfaction with Dietary Behaviour. A model of moderated mediation is predicted, whereby the initial predictor (Dietary Goal-Desire Incongruence) predicts the level of the outcome variable, Satisfaction with Dietary Behaviour. We hypothesise that the relationship between these two variables will be mediated by Trait Self-Control and that the extent that Trait Self-control is allowed to mediate dietary outcome is moderated by both Attentional Bias for Food and Motivation for Dietary Self-control. The analysis will be conducted using the PROCESS module in SPSS 23. The results of model testing in this current study will be valuable to direct future research and inform which constructs could be important targets for intervention to improve dietary outcomes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=self-control" title="self-control">self-control</a>, <a href="https://publications.waset.org/abstracts/search?q=diet" title=" diet"> diet</a>, <a href="https://publications.waset.org/abstracts/search?q=model%20testing" title=" model testing"> model testing</a>, <a href="https://publications.waset.org/abstracts/search?q=attentional%20bias" title=" attentional bias"> attentional bias</a>, <a href="https://publications.waset.org/abstracts/search?q=motivation" title=" motivation"> motivation</a> </p> <a href="https://publications.waset.org/abstracts/91435/the-interactions-of-attentional-bias-for-food-trait-self-control-and-motivation-a-model-testing-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/91435.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">170</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> Spiritual Recovery of People with Bipolar Disorder in Malaysia: A Grounded Theory Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamad%20Shariff%20Nurasikin">Mohamad Shariff Nurasikin</a>, <a href="https://publications.waset.org/abstracts/search?q=Paul%20Crawford"> Paul Crawford</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicola%20Wright"> Nicola Wright</a> </p> <p class="card-text"><strong>Abstract:</strong></p> People with any mental disorder can get benefit from the spiritual aspects of life for recovery, particularly in searching for the meaning of life and engaging in meaningful activities. However, little is known about such effects in the population of bipolar disorder. The concepts of spirituality are highly contestable, as they are too broad and removed from the original religious understanding. The concepts are more notable as encompassing multi-dimensional aspects of people’s lives such as social, emotional, and psychological. Viewing that Western or secular worldview dominates most of the literature in spirituality, it is time to explore the concept of spirituality from the Eastern and religious worldview, such as the Malaysian view. Thus, the aim of this study is to provide a conceptual understanding of people with bipolar disorder with a religious affiliation in Malaysia. This study employs a Grounded Theory and explores the narratives from the interviews of 25 participants. The narratives strongly suggest the salient resources or can be referred to as various forms of capital, as in the capital theory, namely, religious, social, psychological, and medicinal. More important is how these capitals are the enablers for recovery in mental health and well-being, where the participants in the sample engage in a more meaningful life and positive adaptations. This study also extends the Bourdieusian spiritual capital, in which the salient resources are termed as the capital bundle. More significant is how the capital bundles are working contiguously in building and accumulating the spiritual capital. This process is conducive to recovery within the social life of people with bipolar disorder or perhaps other mental disorders. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bipolar" title="bipolar">bipolar</a>, <a href="https://publications.waset.org/abstracts/search?q=Bourdeau" title=" Bourdeau"> Bourdeau</a>, <a href="https://publications.waset.org/abstracts/search?q=recovery" title=" recovery"> recovery</a>, <a href="https://publications.waset.org/abstracts/search?q=spiritual" title=" spiritual"> spiritual</a> </p> <a href="https://publications.waset.org/abstracts/63165/spiritual-recovery-of-people-with-bipolar-disorder-in-malaysia-a-grounded-theory-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63165.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">383</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> Self‑reported Auditory Problems Are Associated with Adverse Mental Health Outcomes and Alcohol Misuse in the UK Armed Forces</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fred%20N.%20H.%20Parker">Fred N.

The present study examined the association between auditory problems and probable common mental disorders, post-traumatic stress disorder and alcohol misuse. Methods 5474 serving and ex-service personnel from the UK Armed Forces were examined, selected from those who responded to phase two (data collection 2007–09) and phase three (2014–16) of a military cohort study. Multivariable logistic regression was used to examine the association between auditory problems at phase two and mental health problems at phase three. Results 9.7% of participants reported ever experiencing hearing problems alone, 7.9% reported tinnitus within the last month alone, and 7.8% reported hearing problems with tinnitus. After adjustment, hearing problems with tinnitus at phase two was associated with increased odds of probable common mental disorders (AOR = 1.50, 95% CI 1.09–2.08), post-traumatic stress disorder (AOR = 2.30, 95% CI 1.41–3.76), and alcohol misuse (AOR = 1.94, 95% CI 1.28–2.96) at phase three. Tinnitus alone was associated with probable post-traumatic stress disorder (AOR = 1.80, 95% CI 1.03–3.15); however, hearing problems alone were not associated with any outcomes of interest. Conclusions The association between auditory problems and mental health problems emphasizes the importance of the prevention of auditory problems in the Armed Forces: through enhanced audiometric screening, improved hearing protection equipment, and greater levels of utilization of such equipment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=armed%20forces" title="armed forces">armed forces</a>, <a href="https://publications.waset.org/abstracts/search?q=hearing%20problems" title=" hearing problems"> hearing problems</a>, <a href="https://publications.waset.org/abstracts/search?q=tinnitus" title=" tinnitus"> tinnitus</a>, <a href="https://publications.waset.org/abstracts/search?q=mental%20health" title=" mental health"> mental health</a>, <a href="https://publications.waset.org/abstracts/search?q=alcohol%20misuse" title=" alcohol misuse"> alcohol misuse</a> </p> <a href="https://publications.waset.org/abstracts/142704/selfreported-auditory-problems-are-associated-with-adverse-mental-health-outcomes-and-alcohol-misuse-in-the-uk-armed-forces" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142704.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">166</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> An Evaluation of Different Weed Management Techniques in Organic Arable Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nicola%20D.%20Cannon">Nicola D.

The experiments were designed using randomised complete block and some with split plot arrangements. Sowing date, variety choice, crop height and crop establishment technique have all shown a significant impact on weed infestations. Other techniques have also been investigated but with less clear, but, still often significant effects on weed control including grazing with sheep, undersowing with different legumes and mechanical weeding techniques. Tillage treatments included traditional plough based systems, minimum tillage and direct drilling. Direct drilling had significantly higher weed dry matter than the other two techniques. Taller wheat varieties which do not contain Rht1 or Rht2 had higher weed populations than the wheat without dwarfing genes. Early sown winter wheat had greater weed dry matter than later sown wheat. Grazing with sheep interacted strongly with sowing date, with shorter varieties and also late sowing dates providing much less forage but, grazing did reduce weed biomass in June. Undersowing had mixed impacts which were related to the success of establishment of the undersown legume crop. Weeds are most successfully controlled when a range of techniques are implemented to give the wheat crop the greatest chance of competing with weeds. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=crop%20establishment" title="crop establishment">crop establishment</a>, <a href="https://publications.waset.org/abstracts/search?q=drilling%20date" title=" drilling date"> drilling date</a>, <a href="https://publications.waset.org/abstracts/search?q=grazing" title=" grazing"> grazing</a>, <a href="https://publications.waset.org/abstracts/search?q=undersowing" title=" undersowing"> undersowing</a>, <a href="https://publications.waset.org/abstracts/search?q=varieties" title=" varieties"> varieties</a>, <a href="https://publications.waset.org/abstracts/search?q=weeds" title=" weeds"> weeds</a> </p> <a href="https://publications.waset.org/abstracts/79382/an-evaluation-of-different-weed-management-techniques-in-organic-arable-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79382.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">183</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> Screening of Antiviral Compounds in Medicinal Plants: Non-Volatiles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tomas%20Drevinskas">Tomas Drevinskas</a>, <a href="https://publications.waset.org/abstracts/search?q=Ruta%20Mickiene"> Ruta Mickiene</a>, <a href="https://publications.waset.org/abstracts/search?q=Audrius%20Maruska"> Audrius Maruska</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicola%20Tiso"> Nicola Tiso</a>, <a href="https://publications.waset.org/abstracts/search?q=Algirdas%20Salomskas"> Algirdas Salomskas</a>, <a href="https://publications.waset.org/abstracts/search?q=Raimundas%20Lelesius"> Raimundas Lelesius</a>, <a href="https://publications.waset.org/abstracts/search?q=Agneta%20Karpovaite"> Agneta Karpovaite</a>, <a href="https://publications.waset.org/abstracts/search?q=Ona%20Ragazinskiene"> Ona Ragazinskiene</a>, <a href="https://publications.waset.org/abstracts/search?q=Loreta%20Kubiliene"> Loreta Kubiliene</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Antiviral effect of substances accumulated by plants and natural products is known to ethno-pharmacy and modern day medicine. Antiviral properties are usually assigned to volatile compounds and polyphenols. This research work is divided into several parts and the task of this part was to investigate potential plants, potential substances and potential preparation conditions that can be used for the preparation of antiviral agents. Sixteen different medicinal plants, their parts and two types of propolis were selected for screening. Firstly, extraction conditions of non-volatile compounds were investigated: 3 pre-selected plants were extracted with 5 different ethanol – water mixtures (96%, 75%, 60%, 40%, 20 %, vol.) and bidistilled water. Total phenolic content, total flavonoid content and radical scavenging activity was determined. The results indicated that optimal extrahent is 40%, vol. of ethanol – water mixture. Further investigations were performed with the extrahent of 40%, vol. ethanol – water mixture. All 16 of selected plants, their parts and two types of propolis were extracted using selected extrahent. Determined total phenolic content, total flavonoid content and radical scavenging activity indicated that extracts of Origanum Vulgare L., Mentha piperita L., Geranium macrorrhizum L., Melissa officinalis L. and Desmodium canadence L. contains highest amount of extractable phenolic compounds (7.31, 5.48, 7.88, 8.02 and 7.16 rutin equivalents (mg/ ml) respectively), flavonoid content (2.14, 2.23, 2.49, 0.79 and 1.51 rutin equivalents (mg/ml) respectively) and radical scavenging activity (11.98, 8.72, 13.47, 13.22 and 12.22 rutin equivalents (mg/ml) respectively).

Recently, some researchers have focused on vibrations at low excitation frequency(0.5-5 Hz) which are considered to be the main risk factors for lumbar part of the backbone but they were not applicable to A and B-segment cars regarding to the size and weight. A semi-active system with two symmetric negative stiffness structures (NSS) in parallel to a positive stiffness structure and actuators has been proposed to attenuate low frequency excitation and makes system flexible regarding to different weight of passengers which is applicable for A and B-Segment cars. Here, the 3 degree of freedom system is considered, dynamic equation clearly is presented, then simulated in MATLAB in order to analysis of performance of the system. The design procedure is derived so that the resonance peak of frequency–response curve shift to the left, the isolating range is increased and especially, the peak of the frequency–response curve is minimized. According to ISO standard different class of road profile as an input is applied to the system to evaluate the performance of the system. To evaluate comfort issues, we extract the RMS value of the vertical acceleration acting on the passenger's body. Then apply the band-pass filter, which takes into account the human sensitivity to acceleration. According to ISO, this weighted acceleration is lower than 0.315 m/s^2, so the ride is considered as comfortable. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=low%20frequency%20excitation" title="low frequency excitation">low frequency excitation</a>, <a href="https://publications.waset.org/abstracts/search?q=negative%20stiffness" title=" negative stiffness"> negative stiffness</a>, <a href="https://publications.waset.org/abstracts/search?q=seat%20vehicle" title=" seat vehicle"> seat vehicle</a>, <a href="https://publications.waset.org/abstracts/search?q=vibration%20isolation" title=" vibration isolation"> vibration isolation</a> </p> <a href="https://publications.waset.org/abstracts/36382/design-and-analysis-of-semi-active-isolation-system-in-low-frequency-excitation-region-for-vehicle-seat-to-reduce-discomfort" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36382.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">436</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> Competitor Integration with Voice of Customer Ratings in QFD Studies Using Geometric Mean Based on AHP</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zafar%20Iqbal">Zafar Iqbal</a>, <a href="https://publications.waset.org/abstracts/search?q=Nigel%20P.%20Grigg"> Nigel P.

The method of obtaining improvement ratios (IRs) does not always integrate the competitors’ rating in a systematic way that fully utilises competitor rating information. This can have the effect of diverting QFD practitioners’ attention from a potentially important VOC to less important VOC. In order to enhance QFD analysis, we present a more systematic method for integrating competitor ratings, utilising the geometric mean of the customer rating matrix. In this paper we develop a new approach, based on the Analytic Hierarchy Process (AHP), in which we generating a matrix of multiple comparisons of all competitors, and derive a geometric mean for each competitor. For each VOC an improved IR is derived which-we argue herein - enhances the initial VOC importance ratings by integrating more information about competitor performance. In this way, our method can help overcome one of the possible shortcomings of QFD. We then use a published QFD example from literature as a case study to demonstrate the use of the new AHP-based IRs, and show how these can be used to re-rank existing VOCs to -arguably- better achieve the goal of customer satisfaction in relation VOC ratings and competitors’ rankings. We demonstrate how two dimensional AHP-based geometric mean derived from the multiple competitor comparisons matrix can be useful for analysing competitors’ rankings. Our method utilises an established methodology (AHP) applied within an established application (QFD), but in an original way (through the competitor analysis matrix), to achieve a novel improvement. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=quality%20function%20deployment" title="quality function deployment">quality function deployment</a>, <a href="https://publications.waset.org/abstracts/search?q=geometric%20mean" title=" geometric mean"> geometric mean</a>, <a href="https://publications.waset.org/abstracts/search?q=improvement%20ratio" title=" improvement ratio"> improvement ratio</a>, <a href="https://publications.waset.org/abstracts/search?q=AHP" title=" AHP"> AHP</a>, <a href="https://publications.waset.org/abstracts/search?q=competitors%20ratings" title=" competitors ratings"> competitors ratings</a> </p> <a href="https://publications.waset.org/abstracts/40657/competitor-integration-with-voice-of-customer-ratings-in-qfd-studies-using-geometric-mean-based-on-ahp" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40657.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">366</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> A Critical Discourse Analysis of Intersectionality, the Ideal Worker and the Professionalized UK Non-Profit Sector</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nicola%20Bentham">Nicola Bentham</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Drawing on the concept of the Ideal Worker and Intersectionality as a Critical Social theory, this research examines to what extent minority ethnic female workers are excluded from the Ideal Worker concept in non-profits, specifically whilst these organizations undergo change to become more professionalized. Critical Discourse Analysis was used to analyse semi-structured interviews from 21 workers, including minority ethnic female, male and non-binary workers, who all represent a range of job roles across the non-profit sector (e.g., trustees, consultants, fundraisers, recruiters, Human Resource (HR), Equity, Diversity and Inclusion (EDI) professionals, etc.). Organizational literature, which provides the symbolic capital for the Ideal Worker concept within this sector and used by these workers within career development and recruitment practices, was further examined. Non-profits present an interesting context of tensions, given their historical ethos of philanthropic social change, whilst changing their present-day organisational practices to reflect the professionalized for-profit sector. This research aims to examine the technologies of inclusion that are used to validate the Ideal Worker concept and the tensions between the projected organisational rhetoric advocating for societal change and those internalized organizational practices that perpetuate workplace inequalities for minority ethnic females. In doing so, this research will provide an insight into the interplay between inclusion, performativity and underrepresentation; examining whether the latter can improve. This research contributes to the call for action regarding effective inclusion practices within non-profit organizations by advocating the use of a critical framework to be incorporated within organizational equity and inclusion strategies; thereby enabling effective sector-wide representation for minoritized workers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=critical%20discourse%20analysis" title="critical discourse analysis">critical discourse analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=professionalization" title=" professionalization"> professionalization</a>, <a href="https://publications.waset.org/abstracts/search?q=organizational%20change" title=" organizational change"> organizational change</a>, <a href="https://publications.waset.org/abstracts/search?q=ideal%20worker" title=" ideal worker"> ideal worker</a>, <a href="https://publications.waset.org/abstracts/search?q=non-profit" title=" non-profit"> non-profit</a>, <a href="https://publications.waset.org/abstracts/search?q=third%20sector" title=" third sector"> third sector</a>, <a href="https://publications.waset.org/abstracts/search?q=charity" title=" charity"> charity</a>, <a href="https://publications.waset.org/abstracts/search?q=intersectionality" title=" intersectionality"> intersectionality</a>, <a href="https://publications.waset.org/abstracts/search?q=inclusion" title=" inclusion"> inclusion</a>, <a href="https://publications.waset.org/abstracts/search?q=minority%20ethnic%20female" title=" minority ethnic female"> minority ethnic female</a> </p> <a href="https://publications.waset.org/abstracts/172960/a-critical-discourse-analysis-of-intersectionality-the-ideal-worker-and-the-professionalized-uk-non-profit-sector" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/172960.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">59</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> Agent-Based Modelling to Improve Dairy-origin Beef Production: Model Description and Evaluation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Addisu%20H.%20Addis">Addisu H.

This study developed an ABM to represent a pasture-based beef cattle finishing systems in New Zea-land (NZ) using attributes of the rearer, finisher, and processor, as well as specific attributes of dairy-origin beef cattle. The model was parameterized using values representing 1% of NZ dairy-origin cattle, and 10% of rearers and finishers in NZ. The cattle agent consisted of 32% Holstein-Friesian, 50% Holstein-Friesian–Jersey crossbred, and 8% Jersey, with the remainder being other breeds. Rearers and finishers repetitively and simultaneously interacted to determine the type and number of cattle populating the finishing system. Rearers brought in four-day-old spring-born calves and reared them until 60 calves (representing a full truck load) on average had a live weight of 100 kg before selling them on to finishers. Finishers mainly attained weaners from rearers, or directly from dairy farmers when weaner demand was higher than the supply from rearers. Fast-growing cattle were sent for slaughter before the second winter, and the re-mainder were sent before their third winter. The model finished a higher number of bulls than heifers and steers, although it was 4% lower than the industry reported value. Holstein-Friesian and Holstein-Friesian–Jersey-crossbred cattle dominated the dairy-origin beef finishing system. Jersey cattle account for less than 5% of total processed beef cattle. Further studies to include re-tailer and consumer perspectives and other decision alternatives for finishing farms would im-prove the applicability of the model for decision-making processes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agent-based%20modelling" title="agent-based modelling">agent-based modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=dairy%20cattle" title=" dairy cattle"> dairy cattle</a>, <a href="https://publications.waset.org/abstracts/search?q=beef%20finishing" title=" beef finishing"> beef finishing</a>, <a href="https://publications.waset.org/abstracts/search?q=rearers" title=" rearers"> rearers</a>, <a href="https://publications.waset.org/abstracts/search?q=finishers" title=" finishers"> finishers</a> </p> <a href="https://publications.waset.org/abstracts/159011/agent-based-modelling-to-improve-dairy-origin-beef-production-model-description-and-evaluation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159011.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">99</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">17</span> Personality-Focused Intervention for Adolescents: Impact on Bullying and Distress</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Erin%20V.%20Kelly">Erin V.

The current study aimed to examine the impact of a personality-targeted intervention (Preventure) on bullying (victimization and perpetration) and distress among adolescent victims/bullies with high-risk personality types. Method: A cluster randomized trial (RCT) was conducted in 26 secondary schools (2190 students) in NSW and Victoria, Australia, as part of the Climate Schools and Preventure trial. The schools were randomly allocated to Preventure (13 schools received Preventure, 13 did not). Students were followed up at 4 time points (6, 12, 24 and 36 months post-baseline). Preventure involves two group sessions, based on cognitive behavioral therapy, and tailored to four personality types shown to increase risk of substance misuse and other emotional and behavioural problems, including impulsivity, sensation-seeking, anxiety sensitivity and hopelessness. Students were allocated to the personality-targeted groups based on their scores on the Substance Use Risk Profile Scale. Bullying was measured using an amended version of the Revised Olweus Bully/Victim Scale. Psychological distress was measured using the Kessler Psychological Distress Scale. Results: Among high-risk students classified as victims at baseline, those in Preventure schools reported significantly less victimization and distress over time than those in control schools. Among high-risk students classified as bullies at baseline, those in Preventure schools reported significantly less distress over time than those in control schools (no difference for perpetration). Conclusion: Preventure is a promising intervention for reducing bullying victimization and psychological distress among adolescents involved in bullying. <p
