Method: In order to develop this research, we used a systematic bibliographic review, following the process of investigation, cataloging, careful evaluation and synthesis of the documentation, associated with the method of thanatological hemenutics proposed by Elisabeth Kübler-Ross. Conclusion: After a significant loss, especially the death of a loved one or family member, it is normal for the mourner, motivated by absence, to have a false perception of the presence of the deceased. This phenomenon happens whenever the mourner is in the middle of the crowd, because his selective attention causes him to perceive physical characteristics, tone of voice, or feel fragrance of the perfume that the deceased possessed. Details characterizing the dead are perceived by the mourner because he seeks the presence in the absence. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elisabeth%20K%C3%BCbler-Ross" title="Elisabeth Kübler-Ross">Elisabeth Kübler-Ross</a>, <a href="https://publications.waset.org/abstracts/search?q=mourning" title=" mourning"> mourning</a>, <a href="https://publications.waset.org/abstracts/search?q=selective%20attention" title=" selective attention"> selective attention</a>, <a href="https://publications.waset.org/abstracts/search?q=thanatology" title=" thanatology"> thanatology</a> </p> <a href="https://publications.waset.org/abstracts/83330/selective-attention-as-a-search-for-the-deceased-during-the-mourning-process" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83330.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">418</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">74</span> De-Novo Structural Elucidation from Mass/NMR Spectra</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ismael%20Zamora">Ismael Zamora</a>, <a href="https://publications.waset.org/abstracts/search?q=Elisabeth%20Ortega"> Elisabeth Ortega</a>, <a href="https://publications.waset.org/abstracts/search?q=Tatiana%20Radchenko"> Tatiana Radchenko</a>, <a href="https://publications.waset.org/abstracts/search?q=Guillem%20Plasencia"> Guillem Plasencia</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The structure elucidation based on Mass Spectra (MS) data of unknown substances is an unresolved problem that affects many different fields of application. The recent overview of software available for structure elucidation of small molecules has shown the demand for efficient computational tool that will be able to perform structure elucidation of unknown small molecules and peptides. We developed an algorithm for De-Novo fragment analysis based on MS data that proposes a set of scored and ranked structures that are compatible with the MS and MSMS spectra. Several different algorithms were developed depending on the initial set of fragments and the structure building processes. Also, in all cases, several scores for the final molecule ranking were computed. They were validated with small and middle databases (DB) with the eleven test set compounds. Similar results were obtained from any of the databases that contained the fragments of the expected compound. We presented an algorithm. Or De-Novo fragment analysis based on only mass spectrometry (MS) data only that proposed a set of scored/ranked structures that was validated on different types of databases and showed good results as proof of concept. Moreover, the solutions proposed by Mass Spectrometry were submitted to the prediction of NMR spectra in order to elucidate which of the proposed structures was compatible with the NMR spectra collected. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=De%20Novo" title="De Novo">De Novo</a>, <a href="https://publications.waset.org/abstracts/search?q=structure%20elucidation" title=" structure elucidation"> structure elucidation</a>, <a href="https://publications.waset.org/abstracts/search?q=mass%20spectrometry" title=" mass spectrometry"> mass spectrometry</a>, <a href="https://publications.waset.org/abstracts/search?q=NMR" title=" NMR"> NMR</a> </p> <a href="https://publications.waset.org/abstracts/58568/de-novo-structural-elucidation-from-massnmr-spectra" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58568.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">295</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">73</span> Memorizing Music and Learning Strategies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elisabeth%20Eder">Elisabeth Eder</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Memorizing music plays an important role for instrumentalists and has been researched very little so far. Almost every musician is confronted with memorizing music in the course of their musical career. For numerous competitions, examinations (e.g., at universities, music schools), solo performances, and the like, memorization is a requirement. Learners are often required to learn a piece by heart but are rarely given guidance on how to proceed. This was also confirmed by Eder's preliminary study to examine the topicality and relevance of the topic, in which 111 instrumentalists took part. The preliminary study revealed a great desire for more knowledge or information about learning strategies as well as a greater sense of security when performing by heart on stage through the use of learning strategies by those musicians who use learning strategies. Eder’s research focuses on learning strategies for memorizing music. As part of a large-scale empirical study – an online questionnaire translated into 10 languages was used to conduct the study – 1091 musicians from 64 different countries described how they memorize. The participants in the study also evaluated their learning strategies and justified their choice in terms of their degree of effectiveness. Based on the study and pedagogical literature, 100 learning strategies were identified and categorized; the strategies were examined with regard to their effectiveness, and instrument-specific, age-specific, country-specific, gender-specific, and education-related differences and similarities concerning the choice of learning strategies were investigated. Her research also deals with forms and models of memory and how music-related information can be stored and retrieved and also forgotten again. A further part is devoted to the possibilities that teachers and learners have to support the process of memorization independently of learning strategies. The findings resulting from Elisabeth Eder's research should enable musicians and instrumental students to memorize faster and more confidently. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=memorizing%20music" title="memorizing music">memorizing music</a>, <a href="https://publications.waset.org/abstracts/search?q=learning%20strategies" title=" learning strategies"> learning strategies</a>, <a href="https://publications.waset.org/abstracts/search?q=empirical%20study" title=" empirical study"> empirical study</a>, <a href="https://publications.waset.org/abstracts/search?q=effectiveness%20of%20strategies" title=" effectiveness of strategies"> effectiveness of strategies</a> </p> <a href="https://publications.waset.org/abstracts/183397/memorizing-music-and-learning-strategies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183397.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">42</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">72</span> Visual Impairment Through Contextualized Lived Experiences: The Story of James</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jentel%20Van%20Havermaet">Jentel Van Havermaet</a>, <a href="https://publications.waset.org/abstracts/search?q=Geert%20Van%20Hove"> Geert Van Hove</a>, <a href="https://publications.waset.org/abstracts/search?q=Elisabeth%20De%20Schauwer"> Elisabeth De Schauwer</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study re-conceptualizes visual impairment in the interdependent context of James, his family, and allies.

The quest, nevertheless, to stimulate the interest in a non-violent, non-contemptuous education able to balance, improves and if necessary, transforms the relationships that have made it a space of privilege and exclusion. We all know the school has found itself in need of rethinking diversity while developing awareness of its own role in reproducing inequality.

In this work, tetracycline (TC) has been employed as chemo-sensor for the recognition of Al³⁺ without interring other ions, and the results show that it enhances the fluorescence intensity for Al³⁺ and there is no interference from other coexisting cation ions (Cd²⁺, Ni²⁺, Co²⁺, Sr²⁺, Mg²⁺, Fe³⁺, K⁺, Sm³⁺, Ag⁺, Na⁺, Ba²⁺, Zn²⁺, and Mn²⁺). For the addition of Cu²⁺ to [TET-Al³⁺], it appears that the intensity of fluorescence has been quenched. Other combinations of metal ions in addition to TC do not change the fluorescence behavior. The stoichiometry determined by Job´s plot for the interaction of TC with Al³⁺ was found to be 1:1. Importantly, the detection of Al³⁺⁺ successfully employed in the real samples like living cells, and it was found that TC efficiently performs as a fluorescent probe for Al³⁺ ion in living systems, especially in Saccharomyces cerevisiae; this is confirmed by confocal laser scanning microscopy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chemo-sensor" title="chemo-sensor">chemo-sensor</a>, <a href="https://publications.waset.org/abstracts/search?q=recognition%20of%20Al%C2%B3%E2%81%BA%20ion" title=" recognition of Al³⁺ ion"> recognition of Al³⁺ ion</a>, <a href="https://publications.waset.org/abstracts/search?q=Saccharomyces%20cerevisiae" title=" Saccharomyces cerevisiae"> Saccharomyces cerevisiae</a>, <a href="https://publications.waset.org/abstracts/search?q=tetracycline" title=" tetracycline"> tetracycline</a>, <a href="https://publications.waset.org/abstracts/search?q=" title=""></a> </p> <a href="https://publications.waset.org/abstracts/94375/tetracycline-as-chemosensor-for-simultaneous-recognition-of-al3-application-to-bio-imaging-for-living-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/94375.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">189</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">68</span> A Fellowship of Philosophy: Übermensch and the Will to Power in Tolkien</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%20Mirzabayati">Ali Mirzabayati</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This article associates Tolkien’s concept of power with Nietzsche’s Übermensch. Despite his catholic beliefs, Tolkien refuses to create religiously motivated characters, opening room for existentialist decisions. Who is an Übermensch? What Tolkienian character resembles this concept the most? To tend to these questions, the article studies the case of Adolf Hitler and Elisabeth Nietzsche, manipulating Nietzschean philosophy. An investigation of the Nazis’ misuse of philosophy, art, and myth for political advantage introduces a Nazi version of Übermensch, best reflected in Sauron and Saruman. Unlike the Nazi version, Nietzschean Übermensch is proven to emphasize internal power and seek harmony within one’s desires. Tolkien’s best candidates for Übermensch, Aragorn and Bilbo are examined through Nietzsche’s three metamorphoses of becoming a higher spirit. What is more, I will study Nietzsche’s admiration for cheer and eating, the main characteristics of the hobbits, to strengthen his bond with Tolkien. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tolkien" title="Tolkien">Tolkien</a>, <a href="https://publications.waset.org/abstracts/search?q=Nietzsche" title=" Nietzsche"> Nietzsche</a>, <a href="https://publications.waset.org/abstracts/search?q=literature" title=" literature"> literature</a>, <a href="https://publications.waset.org/abstracts/search?q=fantasy" title=" fantasy"> fantasy</a>, <a href="https://publications.waset.org/abstracts/search?q=history" title=" history"> history</a>, <a href="https://publications.waset.org/abstracts/search?q=philosophy" title=" philosophy"> philosophy</a> </p> <a href="https://publications.waset.org/abstracts/149835/a-fellowship-of-philosophy-ubermensch-and-the-will-to-power-in-tolkien" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149835.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">126</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">67</span> Exploring the Impact of Location on Urban and Peri-Urban Farming: A Case Study from Lusaka, Zambia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cecilia%20Elisabeth%20F%C3%A5hraeus">Cecilia Elisabeth Fåhraeus</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In 2016, this author conducted a study on agricultural livelihoods in urban and peri-urban low-income settings in Lusaka, Zambia. The overarching aim was to determine the impact of physical space on agricultural activities, with a particular emphasis on geographical distinctions between urban and peri-urban environments. Agricultural activities among the areas’ residents were mapped through questionnaires, interviews and observations, and included variables such as type of activity and product; degree of marketization; inputs; location of production, storage and vending; labour distribution; production constraints, and associated mobility patterns, among others. The study confirmed that spatial idiosyncrasies of urban and peri-urban environments both enabled and constrained agricultural activity, but not always as anticipated. There were also cross-cutting issues on which physical space appeared to have a limited impact. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agricultural%20production%20systems" title="agricultural production systems">agricultural production systems</a>, <a href="https://publications.waset.org/abstracts/search?q=geography" title=" geography"> geography</a>, <a href="https://publications.waset.org/abstracts/search?q=low-income%20settlements" title=" low-income settlements"> low-income settlements</a>, <a href="https://publications.waset.org/abstracts/search?q=Lusaka" title=" Lusaka"> Lusaka</a>, <a href="https://publications.waset.org/abstracts/search?q=peri-urban" title=" peri-urban"> peri-urban</a>, <a href="https://publications.waset.org/abstracts/search?q=urban" title=" urban"> urban</a> </p> <a href="https://publications.waset.org/abstracts/61787/exploring-the-impact-of-location-on-urban-and-peri-urban-farming-a-case-study-from-lusaka-zambia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61787.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">330</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">66</span> Portable Hands-Free Process Assistant for Gas Turbine Maintenance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elisabeth%20Brandenburg">Elisabeth Brandenburg</a>, <a href="https://publications.waset.org/abstracts/search?q=Robert%20Woll"> Robert Woll</a>, <a href="https://publications.waset.org/abstracts/search?q=Rainer%20Stark"> Rainer Stark</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents how smart glasses and voice commands can be used for improving the maintenance process of industrial gas turbines.

In the following, it will be presented how the approach of user-centered design and the method of paper prototyping have been successfully applied in order to design a user interface and a corresponding workflow model that describes the possible interaction patterns between the user and the interface. The presented evaluation of these results suggests that the assistance system could help the user by rendering multiple manual activities obsolete, thus allowing him to work hands-free and to save time for generating protocols. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=paper%20prototyping" title="paper prototyping">paper prototyping</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20glasses" title=" smart glasses"> smart glasses</a>, <a href="https://publications.waset.org/abstracts/search?q=turbine%20maintenance" title=" turbine maintenance"> turbine maintenance</a>, <a href="https://publications.waset.org/abstracts/search?q=user%20centered%20design" title=" user centered design"> user centered design</a> </p> <a href="https://publications.waset.org/abstracts/54380/portable-hands-free-process-assistant-for-gas-turbine-maintenance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54380.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">321</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">65</span> Comparing Sounds of the Singing Voice</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Christel%20Elisabeth%20Bonin">Christel Elisabeth Bonin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This experiment aims at showing that classical singing and belting have both different singing qualities, but singing with a speaking voice has no singing quality. For this purpose, a singing female voice was recorded on four different tone pitches, singing the vowel ‘a’ by using 3 different kinds of singing - classical trained voice, belting voice and speaking voice. The recordings have been entered in the Software Praat. Then the formants of each recorded tone were compared to each other and put in relationship to the singer’s formant. The visible results are taken as an indicator of comparable sound qualities of a classical trained female voice and a belting female voice concerning the concentration of overtones in F1 to F5 and a lack of sound quality in the speaking voice for singing purpose. The results also show that classical singing and belting are both valuable vocal techniques for singing due to their richness of overtones and that belting is not comparable to shouting or screaming. Singing with a speaking voice in contrast should not be called singing due to the lack of overtones which means by definition that there is no musical tone. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=formants" title="formants">formants</a>, <a href="https://publications.waset.org/abstracts/search?q=overtone" title=" overtone"> overtone</a>, <a href="https://publications.waset.org/abstracts/search?q=singer%E2%80%99s%20formant" title=" singer’s formant"> singer’s formant</a>, <a href="https://publications.waset.org/abstracts/search?q=singing%20voice" title=" singing voice"> singing voice</a>, <a href="https://publications.waset.org/abstracts/search?q=belting" title=" belting"> belting</a>, <a href="https://publications.waset.org/abstracts/search?q=classical%20singing" title=" classical singing"> classical singing</a>, <a href="https://publications.waset.org/abstracts/search?q=singing%20with%20the%20speaking%20voice" title=" singing with the speaking voice"> singing with the speaking voice</a> </p> <a href="https://publications.waset.org/abstracts/41946/comparing-sounds-of-the-singing-voice" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41946.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">328</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">64</span> Teacher Mental Health during Online Teaching</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elisabeth%20Desiana%20Mayasari">Elisabeth Desiana Mayasari</a>, <a href="https://publications.waset.org/abstracts/search?q=Laurensia%20Aptik%20Evanjeli"> Laurensia Aptik Evanjeli</a>, <a href="https://publications.waset.org/abstracts/search?q=Brigitta%20Erlita%20Tri%20Anggadewi"> Brigitta Erlita Tri Anggadewi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The condition of the COVID-19 pandemic demands adaptation in various aspects of human life, including in the field of education. Teachers are expected to do distance learning or Learning From Home (LFH). The teacher said that he experienced stress, anxiety, feeling depressed, and afraid based on the interview. Learning adaptations and pandemic situations can impact the mental health of teachers, so the purpose of this study is to determine the mental health of teachers while teaching online. This research was conducted with a quantitative approach using a survey method. The subjects in this study were 330 elementary school teachers under the auspices of a foundation in Yogyakarta. Teachers' mental health was measured using the Indonesian version of The Mental Health Inventory (MHI-38), which has a reliability of 0.888. The results showed that the teachers generally had a good mental health condition marked by a lower negative aspect score than the positive aspect. In addition, the overall mental health aspect shows that some teachers have better mental health when compared to the average score, as well as higher positive aspect scores in all sub-aspects. <p class="card-text"><strong>Keywords:</strong> <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=teacher" title=" teacher"> teacher</a>, <a href="https://publications.waset.org/abstracts/search?q=COVID-19%20pandemic" title=" COVID-19 pandemic"> COVID-19 pandemic</a>, <a href="https://publications.waset.org/abstracts/search?q=MHI-38" title=" MHI-38"> MHI-38</a> </p> <a href="https://publications.waset.org/abstracts/143897/teacher-mental-health-during-online-teaching" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143897.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">63</span> Porous Ni Electrodes Modified with Au Nanoparticles for Hydrogen Production</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=V.%20P%C3%A9rez-Herranz">V.

The supporting macroporous Ni electrodes have been obtained by means of the electrodeposition at high current densities. Then, the Au nanoparticles were synthesized and added to the electrode surface. The electrocatalytic behaviour of the developed electrocatalysts was studied by means of pseudo-steady-state polarization curves, electrochemical impedance spectroscopy (EIS) and hydrogen discharge curves. The size of the Au synthetized nanoparticles shows a monomodal distribution, with a very sharp band between 10 and 50 nm. The characteristic parameters d10, d50 and d90 were 14, 20 and 31 nm respectively. From Tafel polarization data has been concluded that the Au nanoparticles improve the catalytic activity of the developed electrodes towards the HER respect to the macroporous Ni electrodes. EIS permits to obtain the electrochemically active area by means of the roughness factor value. All the developed electrodes show roughness factor values in the same order of magnitude. From the activation energy results it can be concluded that the Au nanoparticles improve the intrinsic catalytic activity of the macroporous Ni electrodes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Au%20nano%20particles" title="Au nano particles">Au nano particles</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrogen%20evolution%20reaction" title=" hydrogen evolution reaction"> hydrogen evolution reaction</a>, <a href="https://publications.waset.org/abstracts/search?q=porous%20Ni%20electrodes" title=" porous Ni electrodes"> porous Ni electrodes</a>, <a href="https://publications.waset.org/abstracts/search?q=electrochemical%20impedance%20spectroscopy" title=" electrochemical impedance spectroscopy "> electrochemical impedance spectroscopy </a> </p> <a href="https://publications.waset.org/abstracts/27355/porous-ni-electrodes-modified-with-au-nanoparticles-for-hydrogen-production" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27355.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">622</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">62</span> School Autonomy in the United Kingdom: A Correlational Study Applied to English Principals</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pablo%20Javier%20Ortega-Rodriguez">Pablo Javier Ortega-Rodriguez</a>, <a href="https://publications.waset.org/abstracts/search?q=Francisco%20Jose%20Pozuelos-Estrada"> Francisco Jose Pozuelos-Estrada</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Recently, there has been a renewed interest in school autonomy in the United Kingdom and its impact on students' outcomes. English principals have a pivotal role in decision-making. The aim of this paper is to explore the correlation between the type of school (public or private) and the considerable responsibilities of English principals which participated in PISA 2015. The final sample consisted of 419 principals. Descriptive data (percentages and means) were generated for the variables related to professional autonomy. Pearson's chi-square test was used to determine if there is an association between the type of school and principals' responsibilities for relevant tasks. Statistical analysis was performed using SPSS software, version 22. Findings suggest a significant correlation between the type of school and principals' responsibility for firing teachers and formulating the school budget. This study confirms that the type of school is not associated with principals' responsibility for choosing which textbooks are used at school. The present study establishes a quantitative framework for defining four models of professional autonomy and some proposals to improve school autonomy in the United Kingdom. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=decision%20making" title="decision making">decision making</a>, <a href="https://publications.waset.org/abstracts/search?q=principals" title=" principals"> principals</a>, <a href="https://publications.waset.org/abstracts/search?q=professional%20autonomy" title=" professional autonomy"> professional autonomy</a>, <a href="https://publications.waset.org/abstracts/search?q=school%20autonomy" title=" school autonomy"> school autonomy</a> </p> <a href="https://publications.waset.org/abstracts/99907/school-autonomy-in-the-united-kingdom-a-correlational-study-applied-to-english-principals" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99907.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">796</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">61</span> Study of the Transport of Multivalent Metal Cations Through Cation-Exchange Membranes by Electrochemical Impedance Spectroscopy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=V.%20P%C3%A9rez-Herranz">V.

This technique enables the identification of the ionic-transport characteristics and to distinguish between different transport mechanisms occurring at different current density ranges. The impedance spectra are dependent on the applied dc current density, on the type of cation and on the concentration. When the applied dc current density increases, the diameter of the impedance spectra loops increases because all the components of membrane system resistance increase. The diameter of the impedance plots decreases in the order of Na(I), Ni(II) and Cr(III) due to the increased interactions between the negatively charged sulfonic groups of the membrane and the cations with greater charge. Nyquist plots are shifted towards lower values of the real impedance, and its diameter decreases with the increase of concentration due to the decrease of the solution resistance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ion-exchange%20membranes" title="ion-exchange membranes">ion-exchange membranes</a>, <a href="https://publications.waset.org/abstracts/search?q=Electrochemical%20Impedance%20Spectrocopy" title=" Electrochemical Impedance Spectrocopy"> Electrochemical Impedance Spectrocopy</a>, <a href="https://publications.waset.org/abstracts/search?q=multivalent%20metal%20cations" title=" multivalent metal cations"> multivalent metal cations</a>, <a href="https://publications.waset.org/abstracts/search?q=membrane%20system" title=" membrane system"> membrane system</a> </p> <a href="https://publications.waset.org/abstracts/22796/study-of-the-transport-of-multivalent-metal-cations-through-cation-exchange-membranes-by-electrochemical-impedance-spectroscopy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22796.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">529</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">60</span> Access to Health Data in Medical Records in Indonesia in Terms of Personal Data Protection Principles: The Limitation and Its Implication</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anny%20Retnowati">Anny Retnowati</a>, <a href="https://publications.waset.org/abstracts/search?q=Elisabeth%20Sundari"> Elisabeth Sundari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research aims to elaborate the meaning of personal data protection principles on patient access to health data in medical records in Indonesia and its implications.

Most of the movements were probably composed in the late 1950s. As the finale was missing, Gunther Schuller, the conductor of the world premiere in 1989, decided to improvise one with the orchestra, using Mingus as a guide. The aim of this paper is to analyze ‘Main Score Part I ‘ and ‘Main Score Part II’ and to look into the score of Mingus’ reconstructed compositions under particular observation of the new finale, ‘Main Score Reprise’. There, Mingus left instructions for a return to the opening section of ‘Epitaph’. By examining ‘Epitaph’ in the historical context of Jazz between 1955 to 1967 and the 1980s and comparing the finale of ‘Epitaph’, created - or better said: improvised - by the musicians of the 1989 world premiere with the opening section, at first it will be interesting to discover at which point Gunther Schuller followed Mingus creative process and brought it to life in 1989. Finally, it will be speculated if Charles Mingus composition still represents a foresight of Jazz nearly 30 years after its creation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=epitaph" title="epitaph">epitaph</a>, <a href="https://publications.waset.org/abstracts/search?q=Charles%20Mingus" title=" Charles Mingus"> Charles Mingus</a>, <a href="https://publications.waset.org/abstracts/search?q=Gunter%20Schuller" title=" Gunter Schuller"> Gunter Schuller</a>, <a href="https://publications.waset.org/abstracts/search?q=jazz%20reception" title=" jazz reception"> jazz reception</a>, <a href="https://publications.waset.org/abstracts/search?q=bebop" title=" bebop"> bebop</a>, <a href="https://publications.waset.org/abstracts/search?q=hardbop" title=" hardbop"> hardbop</a>, <a href="https://publications.waset.org/abstracts/search?q=Duke%20Ellington" title=" Duke Ellington"> Duke Ellington</a>, <a href="https://publications.waset.org/abstracts/search?q=black" title=" black"> black</a>, <a href="https://publications.waset.org/abstracts/search?q=brown%20and%20beige" title=" brown and beige"> brown and beige</a>, <a href="https://publications.waset.org/abstracts/search?q=African-American%20music" title=" African-American music"> African-American music</a>, <a href="https://publications.waset.org/abstracts/search?q=free-jazz" title=" free-jazz"> free-jazz</a> </p> <a href="https://publications.waset.org/abstracts/41947/epitaph-charles-mingus-foresight-of-jazz" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41947.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">314</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">58</span> Evaluation of Corrosion Behaviour of Coatings Applied in a High-Strength Low Alloy Steel in Different Climatic Cabinets</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Raquel%20Bayon">Raquel Bayon</a>, <a href="https://publications.waset.org/abstracts/search?q=Ainara%20Lopez-Ortega"> Ainara Lopez-Ortega</a>, <a href="https://publications.waset.org/abstracts/search?q=Elena%20Rodriguez"> Elena Rodriguez</a>, <a href="https://publications.waset.org/abstracts/search?q=Amaya%20Igartua"> Amaya Igartua</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Corrosion is one of the most concerning phenomenon that accelerates material degradation in offshore applications. In order to avoid the premature failure of metallic materials in marine environments, organic coatings have widely been used, due to their elevated corrosion resistance. Thermally-sprayed metals have recently been used in offshore applications, whereas ceramic materials are usually less employed, due to their high cost. The protectiveness of the coatings can be evaluated and categorized in corrosivity categories in accordance with the ISO 12944-6 Standard. According to this standard, for coatings that are supposed to work in marine environments, a C5-M category is required for components working out of the water or partially immersed in the splash zone, and an Im2 category for totally immersed components. C5-M/Im-2 high category would correspond to a durability of more than 20 years without maintenance in accordance with ISO 12944 and NORSOK M501 standards. In this work, the corrosion behavior of three potential coatings used in offshore applications has been evaluated. For this aim, the materials have been subjected to different environmental conditions in several climatic chambers (humidostatic, climatic, immersion, UV and salt-fog). The category of the coatings to each condition has been selected, in accordance with the previously mentioned standard. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cabinet" title="cabinet">cabinet</a>, <a href="https://publications.waset.org/abstracts/search?q=coatings" title=" coatings"> coatings</a>, <a href="https://publications.waset.org/abstracts/search?q=corrosion" title=" corrosion"> corrosion</a>, <a href="https://publications.waset.org/abstracts/search?q=offshore" title=" offshore"> offshore</a> </p> <a href="https://publications.waset.org/abstracts/58681/evaluation-of-corrosion-behaviour-of-coatings-applied-in-a-high-strength-low-alloy-steel-in-different-climatic-cabinets" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58681.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">420</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">57</span> Corrosion and Tribocorrosion Behaviour of Potential Coatings Applied in High-Strength Low-Alloy Steel for Offshore Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ainara%20Lopez-Ortega">Ainara Lopez-Ortega</a>, <a href="https://publications.waset.org/abstracts/search?q=Raquel%20Bayon"> Raquel Bayon</a>, <a href="https://publications.waset.org/abstracts/search?q=Elena%20Rodriguez"> Elena Rodriguez</a>, <a href="https://publications.waset.org/abstracts/search?q=Amaya%20Igartua"> Amaya Igartua</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The materials used in offshore structural applications are continuously subjected to aggressive environmental conditions that accelerate their degradation, thus shortening their useful life. Wear, corrosion and the effect of marine microorganisms are the main processes taking place in marine environments, and whenever they occur simultaneously the durability of materials is strongly reduced. In the present work, the tribocorrosion behaviour of a High-Strength Low-Alloy (HSLA) steel and three coatings commonly used for protecting offshore components has been studied by means of unidirectional tribological tests in synthetic seawater. The coatings were found to enhance the tribological response of the uncoated steel and provide the system with improved corrosion resistance, in terms of smaller material losses and reduction of friction coefficients. The tests were repeated after ageing the materials in a salt-fog cabinet, and the aging process was found to slightly affect the performance of two of the coatings, in terms of higher material losses, meanwhile the third coating was not affected. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coatings" title="coatings">coatings</a>, <a href="https://publications.waset.org/abstracts/search?q=corrosion" title=" corrosion"> corrosion</a>, <a href="https://publications.waset.org/abstracts/search?q=high-strength%20low-alloy%20steel" title=" high-strength low-alloy steel"> high-strength low-alloy steel</a>, <a href="https://publications.waset.org/abstracts/search?q=seawater" title=" seawater"> seawater</a>, <a href="https://publications.waset.org/abstracts/search?q=tribocorrosion" title=" tribocorrosion"> tribocorrosion</a> </p> <a href="https://publications.waset.org/abstracts/58679/corrosion-and-tribocorrosion-behaviour-of-potential-coatings-applied-in-high-strength-low-alloy-steel-for-offshore-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58679.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">419</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">56</span> Molecular Survey and Genetic Diversity of Bartonella henselae Strains Infecting Stray Cats from Algeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Naouelle%20Azzag">Naouelle Azzag</a>, <a href="https://publications.waset.org/abstracts/search?q=Nadia%20Haddad"> Nadia Haddad</a>, <a href="https://publications.waset.org/abstracts/search?q=Benoit%20Durand"> Benoit Durand</a>, <a href="https://publications.waset.org/abstracts/search?q=Elisabeth%20Petit"> Elisabeth Petit</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Ammouche"> Ali Ammouche</a>, <a href="https://publications.waset.org/abstracts/search?q=Bruno%20Chomel"> Bruno Chomel</a>, <a href="https://publications.waset.org/abstracts/search?q=Henri%20J.%20Boulouis"> Henri J.

In this research, we report the results of a cross sectional study of Bartonella henselae bacteremia in stray cats from Algiers. Whole blood of 227 stray cats from Algiers was tested for the presence of Bartonella species by culture and for the evaluation of the genetic diversity of B. henselae strains by multi-locus variable number of tandem repeats assay (MLVA). Bacteremia prevalence was 17% and only B. henselae was identified. Type I was the predominant type (64%). MLVA typing of 259 strains from 30 bacteremic cats revealed 52 different profiles. 51 of these profiles were specific to Algerian cats/identified for the first time. 20/30 cats (67%) harbored 2 to 7 MLVA profiles simultaneously. The similarity of MLVA profiles obtained from the same cat, neighbor-joining clustering and structure-neighbor clustering showed that such a diversity likely results from two different mechanisms occurring either independently or simultaneously independent infections and genetic drift from a primary strain. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bartonella" title="Bartonella">Bartonella</a>, <a href="https://publications.waset.org/abstracts/search?q=cat" title=" cat"> cat</a>, <a href="https://publications.waset.org/abstracts/search?q=MLVA" title=" MLVA"> MLVA</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic" title=" genetic"> genetic</a> </p> <a href="https://publications.waset.org/abstracts/108213/molecular-survey-and-genetic-diversity-of-bartonella-henselae-strains-infecting-stray-cats-from-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108213.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">149</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">55</span> Azaridachta Indica (Neem) Seed Oil Effect in Experimental Arthritis – Biochemical Parameters Assessment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sasan%20Khademnematolahi">Sasan Khademnematolahi</a>, <a href="https://publications.waset.org/abstracts/search?q=Kevine%20Kamga%20Silihe"> Kevine Kamga Silihe</a>, <a href="https://publications.waset.org/abstracts/search?q=Katar%C3%ADna%20Pru%C5%BEinsk%C3%A1"> Katarína Pružinská</a>, <a href="https://publications.waset.org/abstracts/search?q=Martina%20Chrastina"> Martina Chrastina</a>, <a href="https://publications.waset.org/abstracts/search?q=Elisabeth%20Louise%20Ndjengue%20Mindang"> Elisabeth Louise Ndjengue Mindang</a>, <a href="https://publications.waset.org/abstracts/search?q=Franti%C5%A1ek%20Dr%C3%A1fi"> František Dráfi</a>, <a href="https://publications.waset.org/abstracts/search?q=Katar%C3%ADna%20Bauerov%C3%A1"> Katarína Bauerová</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: In ethnomedicine, plant parts and compounds are traditionally utilized to treat many disorders. Azadirachta indica, known as Neem, has been traditionally used in medicinal practices. Neem has various pharmaceutical activities, such as antioxidant and anti-inflammatory, due to the content of bioactive compounds like nimbolide, azadirachtin, and gedunin.Through its effect on pathological inflammatory processes, supplementation with it could alleviate the symptoms of rheumatoid arthritis (RA). Methods: This research aimed to assess Neem seed oil's impact on rats with adjuvant arthritis. Three doses in monotherapy and two in combination with methotrexate (MTX) have been studied and their effect was compared. Neem p.o. doses of 100, 200, and 300 mg/kg and MTX p.o. doses of 0.3 mg/kg were examined. After clinical parameters assessment, biochemical analysis was performed in plasma. Results: During the acute phase of the experimental arthritis (Day21), levels of MMP-9, MCP-1 and cytokines IL-1beta and IL-17A were measured. The positive results of inflammatory mediators evaluation in plasma encourage additional analysis also in related tissues to prove if Neem seed oil can be used as an adjuvant therapy for RA. Conclusion: In this study, the combination therapy of Neem with MTX was most effective from all therapies investigated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adjuvant" title="adjuvant">adjuvant</a>, <a href="https://publications.waset.org/abstracts/search?q=neem" title=" neem"> neem</a>, <a href="https://publications.waset.org/abstracts/search?q=methotrexate" title=" methotrexate"> methotrexate</a>, <a href="https://publications.waset.org/abstracts/search?q=arthritis" title=" arthritis"> arthritis</a> </p> <a href="https://publications.waset.org/abstracts/186176/azaridachta-indica-neem-seed-oil-effect-in-experimental-arthritis-biochemical-parameters-assessment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186176.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">46</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">54</span> Environment-Specific Political Risk Discourse, Environmental Reputation, and Stock Price Crash Risk</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sohanur%20Rahman">Sohanur Rahman</a>, <a href="https://publications.waset.org/abstracts/search?q=Elisabeth%20Sinnewe"> Elisabeth Sinnewe</a>, <a href="https://publications.waset.org/abstracts/search?q=Larelle%20%28Ellie%29%E2%80%AFChapple"> Larelle (Ellie) Chapple</a>, <a href="https://publications.waset.org/abstracts/search?q=Sarah%20Osborne"> Sarah Osborne</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Greater political attention to global climate change exposes firms to a higher level of political uncertainty, which can lead to adverse capital market consequences. However, a higher level of discourse on environment-specific political risk (EPR) between management and investors can mitigate information asymmetry, followed by less stock price crash risk. This study examines whether EPR discourse in discourse in the earnings conference calls (ECC) reduces firm-level stock price crash risk in the US market. This research also explores if adverse disclosures via media channels further moderates the association between EPR on crash risk. Employing a dataset of 28,933 firm-year observations from 2002 to 2020, the empirical analysis reveals that EPR discourse in ECC reduces future stock price crash risk. However, adverse disclosures via media channels can offset the favourable effect of EPR discourse on crash risk. The results are robust to the potential endogeneity concern in a quasi-natural experiment setting. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=earnings%20conference%20calls" title="earnings conference calls">earnings conference calls</a>, <a href="https://publications.waset.org/abstracts/search?q=environment" title=" environment"> environment</a>, <a href="https://publications.waset.org/abstracts/search?q=environment-specific%20political%20risk%20discourse" title=" environment-specific political risk discourse"> environment-specific political risk discourse</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20disclosures" title=" environmental disclosures"> environmental disclosures</a>, <a href="https://publications.waset.org/abstracts/search?q=information%20asymmetry" title=" information asymmetry"> information asymmetry</a>, <a href="https://publications.waset.org/abstracts/search?q=reputation%20risk" title=" reputation risk"> reputation risk</a>, <a href="https://publications.waset.org/abstracts/search?q=stock%20price%20crash%20risk" title=" stock price crash risk"> stock price crash risk</a> </p> <a href="https://publications.waset.org/abstracts/152590/environment-specific-political-risk-discourse-environmental-reputation-and-stock-price-crash-risk" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152590.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">140</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">53</span> A Contemporary Gender Predominance: A Honduran Textile Manufacturing Diagnose</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jes%C3%BAs%20David%20Argueta%20Moreno">Jesús David Argueta Moreno</a>, <a href="https://publications.waset.org/abstracts/search?q=Taria%20Ruiz"> Taria Ruiz</a>, <a href="https://publications.waset.org/abstracts/search?q=Cesar%20Ortega"> Cesar Ortega</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This qualitative investigation represents the first stage of the human capital engineering analysis, along the small and medium textile manufacturing companies, located on the city of Tegucigalpa, Honduras where the symptoms of the local manufacturing industry´s describe a severe gender displacement phenomenon.

However, when the professional list and tasks to be matched are larger than a few dozens, this process result is far from optimal and takes a long time to be made. Therefore, an automated assignment algorithm for this workforce management problem is needed. The majority of companies are divided into several sectors or departments, where trained employees with different experience levels deal with a large number of tasks daily. Also, the execution order of all tasks is of mater consequence, due to some of these tasks just can be run it if the result of another task is provided. Thus, a wrong execution order leads to large waiting times between consecutive tasks. The desired goal is, therefore, creating accurate matches and a near-optimal execution order that maximizes the number of tasks performed and minimizes the idle time of the expensive skilled employees. The problem described before can be model as a mixed-integer non-linear programming (MINLP) as it will be shown in detail through this paper. A large number of MINLP algorithms have been proposed in the literature. Here, genetic algorithm solutions are considered and a comparison between two different mutation approaches is presented. The simulated results considering different complexity levels of assignment decisions show the appropriateness of the proposed model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=employees" title="employees">employees</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20algorithm" title=" genetic algorithm"> genetic algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=industry%20management" title=" industry management"> industry management</a>, <a href="https://publications.waset.org/abstracts/search?q=workforce" title=" workforce"> workforce</a> </p> <a href="https://publications.waset.org/abstracts/123745/workforce-optimization-fair-workload-balance-and-near-optimal-task-execution-order" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/123745.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">168</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">51</span> Sensitivity Analysis Optimization of a Horizontal Axis Wind Turbine from Its Aerodynamic Profiles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kevin%20Molina">Kevin Molina</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Ortega"> Daniel Ortega</a>, <a href="https://publications.waset.org/abstracts/search?q=Manuel%20Martinez"> Manuel Martinez</a>, <a href="https://publications.waset.org/abstracts/search?q=Andres%20Gonzalez-Estrada"> Andres Gonzalez-Estrada</a>, <a href="https://publications.waset.org/abstracts/search?q=William%20Pinto"> William Pinto</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Due to the increasing environmental impact, the wind energy is getting strong. This research studied the relationship between the power produced by a horizontal axis wind turbine (HAWT) and the aerodynamic profiles used for its construction. The analysis is studied using the Computational Fluid Dynamic (CFD), presenting the parallel between the energy generated by a turbine designed with selected profiles and another one optimized. For the study, a selection process was carried out from profile NACA 6 digits recommended by the National Renewable Energy Laboratory (NREL) for the construction of this type of turbines. The selection was taken into account different characteristics of the wind (speed and density) and the profiles (aerodynamic coefficients Cl and Cd to different Reynolds and incidence angles). From the selected profiles, was carried out a sensitivity analysis optimization process between its geometry and the aerodynamic forces that are induced on it. The 3D model of the turbines was realized using the Blade Element Momentum method (BEM) and both profiles. The flow fields on the turbines were simulated, obtaining the forces induced on the blade, the torques produced and an increase of 3% in power due to the optimized profiles. Therefore, the results show that the sensitivity analysis optimization process can assist to increment the wind turbine power. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blade%20element%20momentum" title="blade element momentum">blade element momentum</a>, <a href="https://publications.waset.org/abstracts/search?q=blade" title=" blade"> blade</a>, <a href="https://publications.waset.org/abstracts/search?q=fluid%20structure%20interaction" title=" fluid structure interaction"> fluid structure interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=horizontal%20axis%20wind%20turbine" title=" horizontal axis wind turbine"> horizontal axis wind turbine</a>, <a href="https://publications.waset.org/abstracts/search?q=profile%20design" title=" profile design"> profile design</a> </p> <a href="https://publications.waset.org/abstracts/85165/sensitivity-analysis-optimization-of-a-horizontal-axis-wind-turbine-from-its-aerodynamic-profiles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85165.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">259</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">50</span> The Meaning of the Best Interests of the Child in Indonesia’s Rampant Phenomenon of Child Marriage</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elisabeth%20Sundari">Elisabeth Sundari</a>, <a href="https://publications.waset.org/abstracts/search?q=Anny%20Retnowati"> Anny Retnowati</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research aims to examine the meaning of 'the best interests of the child' in Indonesia's rampant phenomenon of child marriage. The methodology used empirical and normative legal research by examining the parent's reason and the judges' considerations in granting child marriage dispensation applications. It takes data samples from judges' decisions purposively in two courts that differ in geographical and religious backgrounds to see data variation. Namely, the District Court and Religious Court of Yogyakarta City, as well as Gunung Kidul Regency, in the last three years (2020-2022). It analyses the data qualitatively to explore how judges interpreted 'the best interests of the child' in their decision. The results show that judges granted 100% of all child marriage dispensation applications filed by parents. The three reasons parents gave for applying for dispensation were that they were ashamed of having a pregnant child without being married, followed religious teachings, and obtained legal status for the baby. The judges supported those reasons by granting the dispensation application. The external factor of the child itself influenced the meaning of 'The best interests of the child' in marrying off children in Indonesia, such as cultural taboos, religious teachings, and obtaining legal status for the baby, rather than internal factors of the child, such as the will to marry, the mental and psychological readiness of the child to become a mother, as well as a wife. This research contributes to the finding that external factors, such as local culture and religion, can influence the meaning of 'the best interests of the child.' <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=interests" title="interests">interests</a>, <a href="https://publications.waset.org/abstracts/search?q=child" title=" child"> child</a>, <a href="https://publications.waset.org/abstracts/search?q=Indonesia" title=" Indonesia"> Indonesia</a>, <a href="https://publications.waset.org/abstracts/search?q=marriage" title=" marriage"> marriage</a> </p> <a href="https://publications.waset.org/abstracts/163581/the-meaning-of-the-best-interests-of-the-child-in-indonesias-rampant-phenomenon-of-child-marriage" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163581.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">49</span> Determining Variables in Mathematics Performance According to Gender in Mexican Elementary School</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nora%20Gavira%20Duron">Nora Gavira Duron</a>, <a href="https://publications.waset.org/abstracts/search?q=Cinthya%20Moreda%20Gonzalez-Ortega"> Cinthya Moreda Gonzalez-Ortega</a>, <a href="https://publications.waset.org/abstracts/search?q=Reyna%20Susana%20Garcia%20Ruiz"> Reyna Susana Garcia Ruiz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper objective is to analyze the mathematics performance in the Learning Evaluation National Plan (PLANEA for its Spanish initials: Plan Nacional para la Evaluación de los Aprendizajes), applied to Mexican students who are enrolled in the last elementary-school year over the 2017-2018 academic year. Such test was conducted nationwide in 3,573 schools, using a sample of 108,083 students, whose average in mathematics, on a scale of 0 to 100, was 45.6 points. 75% of the sample analyzed did not reach the sufficiency level (60 points). It should be noted that only 2% got a 90 or higher score result. The performance is analyzed while considering whether there are differences in gender, marginalization level, public or private school enrollment, parents’ academic background, and living-with-parents situation. Likewise, this variable impact (among other variables) on school performance by gender is evaluated, considering multivariate logistic (Logit) regression analysis. The results show there are no significant differences in mathematics performance regarding gender in elementary school; nevertheless, the impact exerted by mothers who studied at least high school is of great relevance for students, particularly for girls. Other determining variables are students’ resilience, their parents’ economic status, and the fact they attend private schools, strengthened by the mother's education. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=multivariate%20regression%20analysis" title="multivariate regression analysis">multivariate regression analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=academic%20performance" title=" academic performance"> academic performance</a>, <a href="https://publications.waset.org/abstracts/search?q=learning%20evaluation" title=" learning evaluation"> learning evaluation</a>, <a href="https://publications.waset.org/abstracts/search?q=mathematics%20result%20per%20gender" title=" mathematics result per gender"> mathematics result per gender</a> </p> <a href="https://publications.waset.org/abstracts/118696/determining-variables-in-mathematics-performance-according-to-gender-in-mexican-elementary-school" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/118696.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">147</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">48</span> The Importance of Outside Classroom Activities in Developing Oral Fluency in an EFL Context</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maaly%20Jarrah">Maaly Jarrah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In a study abroad context, students have the advantage of immersing themselves in the environment of the target language and being exposed to it. However, in and a stay home context, where English is not the mother tongue, students’ exposure to the second language is often times restricted to the classroom. Although language teachers are keen to develop inside class room activities and practices that increase the suitability of students to acquire a second language (Cook & Singleton, 2014), many would agree that class time is too limited to enhance students’ oral fluency skills. Consequently, creating opportunities outside the classroom for students to speak English is an effective strategy in compensating for students’ limited use of the L2. In an argument by Ortega (2012) external classroom activities have equal significance in enabling students learn English as a second language. The author further asserts that the activities provide a non-educational environment from which a student may feel free and comfortable to acquire new language skills. This study investigates the significance of outside classroom activities in promoting students’ oral proficiency. In addition, it reports on students’ perceptions of such activities. 15 participants from the American University of Kuwait took part in this study. Open-ended interviews were done to find out what the participants thought of these activities, and what they gained from them. Interview results show that students found outside classroom activities very effective in improving not only their oral fluency skills, but their confidence and critical thinking skills as well. The implications of this research study are for language practitioners and language programs in the EFL context to be aware of the benefits of incorporating outside classroom activities in language teaching. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=language%20teaching" title="language teaching">language teaching</a>, <a href="https://publications.waset.org/abstracts/search?q=oral%20fluency" title=" oral fluency"> oral fluency</a>, <a href="https://publications.waset.org/abstracts/search?q=outside%20classroom%20activities" title=" outside classroom activities"> outside classroom activities</a> </p> <a href="https://publications.waset.org/abstracts/25679/the-importance-of-outside-classroom-activities-in-developing-oral-fluency-in-an-efl-context" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25679.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">459</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">47</span> Psychosocial Risks and Occupational Health in a Mexican Small and Medium-Sized Enterprises </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Magdalena%20Escamilla%20Quintal">Magdalena Escamilla Quintal</a>, <a href="https://publications.waset.org/abstracts/search?q=Thelma%20Cetina%20Canto"> Thelma Cetina Canto</a>, <a href="https://publications.waset.org/abstracts/search?q=Cecilia%20Aguilar%20Ortega"> Cecilia Aguilar Ortega</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Due to the importance that people represent for companies, the setting of a clear control of the risks that threaten the health and the material and financial resources of workers is essential. It is irrelevant if the company is a small and medium-sized enterprise (SME) or a large multinational, or if it is in the construction or service sector. The risk prevention importance is related to a constitutional and human right that all people have; working in a risk-free environment to prevent accidents or illnesses that may influence their quality of life and the tranquility of their family. Therefore, the objective of this study was to determine the level of psychosocial risks (physical and emotional) of the employees of an SME. The participants of this study were 186 employees of a productive sector SME; 151 men and 35 women, all with an average age of 31.77 years. Their seniority inside the SME was between one month and 19.91 years. Ninety-six workers were from the production area, 28 from the management area, as well as 25 from the sales area and 40 from the supplies area. Ninety-three workers were found in Uman, 78 in Playa del Carmen, 11 in Cancun and seven in Cd. del Carmen. We found a statistically significant relationship between the burnout variable and the engagement and psychosomatic complaints as well as between the variables of sex, burnout and psychosomatic complaints. We can conclude that, for benefit of the SME, that there are low levels of burnout and psychosomatic complaints, the women experience major levels of burnout and the men show major levels of psychosomatic complaints. The findings, contributions, limitations and future proposals will be analyzed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=psychosocial%20risks" title="psychosocial risks">psychosocial risks</a>, <a href="https://publications.waset.org/abstracts/search?q=SME" title=" SME"> SME</a>, <a href="https://publications.waset.org/abstracts/search?q=burnout" title=" burnout"> burnout</a>, <a href="https://publications.waset.org/abstracts/search?q=engagement" title=" engagement"> engagement</a>, <a href="https://publications.waset.org/abstracts/search?q=psychosomatic%20complaints" title=" psychosomatic complaints"> psychosomatic complaints</a> </p> <a href="https://publications.waset.org/abstracts/44947/psychosocial-risks-and-occupational-health-in-a-mexican-small-and-medium-sized-enterprises" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44947.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">367</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">46</span> Applying Business Model Patterns: A Case Study in Latin American Building Industry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=James%20Alberto%20Ortega%20Morales">James Alberto Ortega Morales</a>, <a href="https://publications.waset.org/abstracts/search?q=Nelson%20Andr%C3%A9s%20Mart%C3%ADnez%20Mar%C3%ADn"> Nelson Andrés Martínez Marín</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The bulding industry is one of the most important sectors all around the world in terms of contribution to index like GDP and labor. On the other hand, it is a major contributor to Greenhouse Gases (GHG) and waste generation contributing to global warming. In this sense, it is necessary to establish sustainable practices both from the strategic point of view to the operations point of view as well in all business and industries. Business models don’t scape to this reality attending it´s mediator role between strategy and operations. Business models can turn from the traditional practices searching economic benefits to sustainable bussines models that generate both economic value and value for society and the environment. Recent advances in the analysis of sustainable business models find different classifications that allow finding potential triple bottom line (economic, social and environmental) solutions applicable in every business sector. Into the metioned Advances have been identified, 11 groups and 45 patterns of sustainable business models have been identified; such patterns can be found either in the business models as a whole or found concurrently in their components. This article presents the analysis of a case study, seeking to identify the components and elements that are part of it, using the ECO CANVAS conceptual model. The case study allows showing the concurrent existence of different patterns of business models for sustainability empirically, serving as an example and inspiration for other Latin American companies interested in integrating sustainability into their new and existing business models. <p class="card-text"><strong>Keywords:</strong> <a
