Six monofloral honeys (four strawberry tree, two autumn heather) were analyzed by means of Solid Phase Micro-Extraction (SPME, 60 min, 60 oC) followed by Gas Chromatography coupled to Mass Spectrometry (GC-MS) for the purpose of assessing the botanical origin. A Divinylbenzene/Carboxen/Polydimethylsiloxane (DVB/CAR/PDMS) fiber was employed, and benzophenone was used as internal standard. The volatile compounds with higher concentration (μg/ g of honey expressed as benzophenone) from strawberry tree honey samples, were α-isophorone (2.50-8.12); 3,4,5-trimethyl-phenol (0.20-4.62); 2-hydroxy-isophorone (0.06-0.53); 4-oxoisophorone (0.38-0.46); and β-isophorone (0.02-0.43). Regarding heather honey samples, the most abundant compounds were 1-methoxy-4-propyl-benzene (1.22-1.40); p-anisaldehyde (0.97-1.28); p-anisic acid (0.35-0.58); 2-furaldehyde (0.52-0.57); and benzaldehyde (0.41-0.56). Norisoprenoids are potent floral markers for strawberry-tree honey. β-isophorone is found exclusively in the volatile fraction of this type of honey, while also α-isophorone, 4-oxoisophorone and 2-hydroxy-isophorone could be considered as additional marker compounds. The analysis of autumn heather honey revealed that phenolic compounds are the most abundant and p-anisaldehyde; 1-methoxy-4-propyl-benzene; and p-anisic acid could serve as potent marker compounds. In conclusion, marker compounds for the determination of the botanical origin for these honeys could be identified as several norisoprenoids and phenolic components were found exclusively or in higher concentrations compared to common Greek honey varieties. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=SPME%2FGC-MS" title="SPME/GC-MS">SPME/GC-MS</a>, <a href="https://publications.waset.org/abstracts/search?q=volatile%20compounds" title=" volatile compounds"> volatile compounds</a>, <a href="https://publications.waset.org/abstracts/search?q=heather%20honey" title=" heather honey"> heather honey</a>, <a href="https://publications.waset.org/abstracts/search?q=strawberry%20tree%20honey" title=" strawberry tree honey"> strawberry tree honey</a> </p> <a href="https://publications.waset.org/abstracts/136002/solid-phase-micro-extractiongas-chromatography-mass-spectrometry-study-of-volatile-compounds-from-strawberry-tree-and-autumn-heather-honeys" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/136002.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">200</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">38</span> Women Educational Leaders in an Age of Accountability</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ann%20Vibert">Ann Vibert</a>, <a href="https://publications.waset.org/abstracts/search?q=Heather%20Hemming"> Heather Hemming</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presentation summarizes the findings and implications of research on the plight and practices of women educational leaders in public school systems and in one university. The authors, both women university administrators, are also scholars and researchers of education. The research project on which this paper presentation is based proposed to examine how women educational leaders imagined, experienced, and carried out their leadership roles in the context of a growing local and global accountability-based performativity discourse which is reshaping educational work especially for women, we argue, in both public school and post-secondary sites. The research employed critical ethnographic interviews with 20 women educational leaders in P-12 school systems and three women university level educational leaders. Data were collected on women educational leaders’ perceptions of the effects of accountability and performativity discourses on the nature of their work. Specifically, leaders were asked to speak to whether they experienced a growth in managerial work as a consequence of increased accountability demands; how they experienced their work changing as a consequence of accountability and performativity demands; how these changes impacted the central values they enacted in their work as women educational leaders changes; and how they responded to/negotiated/accommodated changes in the nature of their work developing as a consequence of accountability and performativity frameworks. Findings from the research data and analyses confirm and extend recent scholarly work on the gendered nature of performativity and accountability discourses and frameworks, and their differential effects across differing genders. The oral presentation we propose here focusses on those findings in terms of similarities for women educational leaders across different educational contexts. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=women%20in%20educational%20leadership" title="women in educational leadership">women in educational leadership</a>, <a href="https://publications.waset.org/abstracts/search?q=gender%20and%20educational%20performativity" title=" gender and educational performativity"> gender and educational performativity</a>, <a href="https://publications.waset.org/abstracts/search?q=accountability%20and%20women%20leaders" title=" accountability and women leaders"> accountability and women leaders</a>, <a href="https://publications.waset.org/abstracts/search?q=gender%20and%20educational%20leadership" title=" gender and educational leadership"> gender and educational leadership</a> </p> <a href="https://publications.waset.org/abstracts/64476/women-educational-leaders-in-an-age-of-accountability" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/64476.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">37</span> A Correlational Study: Dark Triad and Self-Restraint among Criminology Students</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mary%20Heather%20Lee%20T.%20Walker">Mary Heather Lee T.

Their behavior must be thoroughly assessed before given a badge of responsibility. Therefore, it is important to highlight their Dark Triad that is composed of Machiavellianism, Narcissism, and Psychopathy which are considered to be controversial variables in the present while self-restraint is considered to be their way of controlling themselves especially in their line of work. The researchers used convenience and random sampling and found the respondents from a private school. Thus, the study’s aim is to determine whether there is a relationship among these variables. Machiavellianism and Psychopathy is linked to Self-Restraint except Narcissism. There are lots of factors that resulted into this. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=criminology" title="criminology">criminology</a>, <a href="https://publications.waset.org/abstracts/search?q=dark%20triad" title=" dark triad"> dark triad</a>, <a href="https://publications.waset.org/abstracts/search?q=self-restraint" title=" self-restraint"> self-restraint</a>, <a href="https://publications.waset.org/abstracts/search?q=students" title=" students"> students</a> </p> <a href="https://publications.waset.org/abstracts/104229/a-correlational-study-dark-triad-and-self-restraint-among-criminology-students" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/104229.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">292</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> The Standardization of Colorado Schools to Offer Opportunity Through Equal Education</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Heather%20Caldwell">Heather Caldwell</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In 1915, state superintendent, Mary C.C. Bradford initiated a state standardization plan in order to improve the quality of schools and the educational experience for all children in Colorado. This plan would change the schools, improving them and offering more opportunities for children, teachers, and the community. In a state where geography limited opportunity to make all schools equal and brought challenges to state school leaders to improve education throughout the state, the leadership prevailed and worked together with local schools and school leaders to make drastic improvements in the curriculum. This paper will discuss this plan and will highlight key contributions to this standardization plan that improved opportunities for all students in the state of Colorado through these educational initiatives. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=history%20of%20education" title="history of education">history of education</a>, <a href="https://publications.waset.org/abstracts/search?q=standardization" title=" standardization"> standardization</a>, <a href="https://publications.waset.org/abstracts/search?q=curriculum" title=" curriculum"> curriculum</a>, <a href="https://publications.waset.org/abstracts/search?q=state%20superintendent" title=" state superintendent"> state superintendent</a>, <a href="https://publications.waset.org/abstracts/search?q=women%20in%20education" title=" women in education"> women in education</a> </p> <a href="https://publications.waset.org/abstracts/183342/the-standardization-of-colorado-schools-to-offer-opportunity-through-equal-education" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183342.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">53</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> The Use of Nuclear Generation to Provide Power System Stability</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Heather%20Wyman-Pain">Heather Wyman-Pain</a>, <a href="https://publications.waset.org/abstracts/search?q=Yuankai%20Bian"> Yuankai Bian</a>, <a href="https://publications.waset.org/abstracts/search?q=Furong%20Li"> Furong Li</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The decreasing use of fossil fuel power stations has a negative effect on the stability of the electricity systems in many countries. Nuclear power stations have traditionally provided minimal ancillary services to support the system but this must change in the future as they replace fossil fuel generators. This paper explains the development of the four most popular reactor types still in regular operation across the world which have formed the basis for most reactor development since their commercialisation in the 1950s. The use of nuclear power in four countries with varying levels of capacity provided by nuclear generators is investigated, using the primary frequency response provided by generators as a measure for the electricity networks stability, to assess the need for nuclear generators to provide additional support as their share of the generation capacity increases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=frequency%20control" title="frequency control">frequency control</a>, <a href="https://publications.waset.org/abstracts/search?q=nuclear%20power%20generation" title=" nuclear power generation"> nuclear power generation</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20system%20stability" title=" power system stability"> power system stability</a>, <a href="https://publications.waset.org/abstracts/search?q=system%20inertia" title=" system inertia"> system inertia</a> </p> <a href="https://publications.waset.org/abstracts/47932/the-use-of-nuclear-generation-to-provide-power-system-stability" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47932.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">437</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> Performance of High Density Genotyping in Sahiwal Cattle Breed</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamid%20Mustafa">Hamid Mustafa</a>, <a href="https://publications.waset.org/abstracts/search?q=Huson%20J.%20Heather"> Huson J.

This is a first attempt to assess the Bovine HD SNP genotyping array in any Pakistani indigenous cattle population. To evaluate these SNPs on genome wide scale, we considered 777,962 SNPs spanning the whole autosomal and X chromosomes in Sahiwal cattle population. Fifteen (15) non related gDNA samples were genotyped with the bovine HD infinium. Approximately 500,939 SNPs were found polymorphic (MAF > 0.05) in Sahiwal cattle population. The results of this study indicate potential application of Bovine High Density SNP genotyping in Pakistani indigenous cattle population. The information generated from this array can be applied in genetic prediction, characterization and genome wide association studies of Pakistani Sahiwal cattle population. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sahiwal%20cattle" title="Sahiwal cattle">Sahiwal cattle</a>, <a href="https://publications.waset.org/abstracts/search?q=polymorphic%20SNPs" title=" polymorphic SNPs"> polymorphic SNPs</a>, <a href="https://publications.waset.org/abstracts/search?q=genotyping" title=" genotyping"> genotyping</a>, <a href="https://publications.waset.org/abstracts/search?q=Pakistan" title=" Pakistan"> Pakistan</a> </p> <a href="https://publications.waset.org/abstracts/40193/performance-of-high-density-genotyping-in-sahiwal-cattle-breed" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40193.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">428</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> Assesment of SNP Variation and Distribution in Pakistani Cattle Breeds using High Density SNP Genotyping</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamid%20Mustafa">Hamid Mustafa</a>, <a href="https://publications.waset.org/abstracts/search?q=Heather%20J.%20Huson"> Heather J.

These include 13 Sahiwal, 09 Red Sindhi, 13 Tharparkar, 08 Achi, 13 Cholistani and 10 Dhanni cattle breeds. Analysis of 500, 939 SNP markers revealed that the mean minor allele frequency (MAF) was 0.21, 0.22, 0.18, 0.23, 0.22 and 0.22 for Sahiwal, Red Sindhi, Tharparkar, Achi, Cholistani and Dhanni respectively. Significant differences of minor allele frequency (MAF) were observed between the indigenous Pakistani cattle population (P<0.001). Across these Pakistani cattle breeds, a common variant MAF (≥0.10 and ≤0.5) accounted for an overall estimated 75.71 % of the 500,939 SNPs and on the average 19.58 % of the markers were monomorphic. Mean observed (HO) and expected (HE) heterozygosities were 0.656 and 0.638, respectively. This primarily study of Pakistani indigenous cattle breeds indicate that this level of SNPs variation can potentially be used for genomic studies for future breeding plans and for farm animal conservation strategies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pakistan" title="Pakistan">Pakistan</a>, <a href="https://publications.waset.org/abstracts/search?q=cattle" title=" cattle"> cattle</a>, <a href="https://publications.waset.org/abstracts/search?q=minor%20allele%20frequency" title=" minor allele frequency"> minor allele frequency</a>, <a href="https://publications.waset.org/abstracts/search?q=SNP" title=" SNP"> SNP</a>, <a href="https://publications.waset.org/abstracts/search?q=variation" title=" variation"> variation</a> </p> <a href="https://publications.waset.org/abstracts/23039/assesment-of-snp-variation-and-distribution-in-pakistani-cattle-breeds-using-high-density-snp-genotyping" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23039.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">649</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> Coping in Your Profession: An Exploratory Analysis of Healthcare Students’ Perceptions of Burnout</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Heather%20Clark">Heather Clark</a>, <a href="https://publications.waset.org/abstracts/search?q=Jon%20Kelly"> Jon Kelly</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Burnout among healthcare professionals has been elevated to a high level of concern. The descriptions of the healthcare workplace often include language such as, stressful, long hours, rotating shifts, weekends and holidays, and exhausting. New graduate healthcare professionals are being sent into the workplace with little to no coping skills, knowledge of signs and symptoms of burnout, or resources that are available. The authors of this study created a university course entitled 'coping in your profession' that enrolled registered nurses, licensed practical nurses, EMTs, nurse assistants, and medical assistants. The course addresses burnout, self-analysis, incivility, coping mechanisms, and organizational responsibilities for employee well-being. The students were surveyed using QualtricsXM that included a pre-course and post-course analysis. Pre-course results showed high levels of individual experiences with burnout and limited knowledge of resources to combat burnout. Post-course results included personal growth and that students’ perception of burnout can be prevented at both the individual and the organization levels. Students also indicated that few to no resources to combat burnout existed at their place of employment. Addressing burnout at the educational level helps prepare graduates with the knowledge and tools to combat burnout at the individual and organization level. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=burnout" title="burnout">burnout</a>, <a href="https://publications.waset.org/abstracts/search?q=coping" title=" coping"> coping</a>, <a href="https://publications.waset.org/abstracts/search?q=healthcare%20workers" title=" healthcare workers"> healthcare workers</a>, <a href="https://publications.waset.org/abstracts/search?q=incivility" title=" incivility"> incivility</a>, <a href="https://publications.waset.org/abstracts/search?q=resilience" title=" resilience"> resilience</a> </p> <a href="https://publications.waset.org/abstracts/124637/coping-in-your-profession-an-exploratory-analysis-of-healthcare-students-perceptions-of-burnout" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/124637.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">31</span> Population Structure Analysis of Pakistani Indigenous Cattle Population by Using High Density SNP Array</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamid%20Mustafa">Hamid Mustafa</a>, <a href="https://publications.waset.org/abstracts/search?q=Huson%20J.%20Heather"> Huson J.

Analyses of population structure and breed diversity have provided insight into the origin and evolution of cattle. In this study, we used a high-density panel of SNP markers to examine population structure and diversity among ten Pakistani indigenous cattle breeds. In total, 25 individuals from three cattle populations, including Achi (n=08), Bhagnari (n=04) and Cholistani (n=13) were genotyped for 777, 962 single nucleotide polymorphism (SNP) markers. Population structure was examined using the linkage model in the program STRUCTURE. After characterizing SNP polymorphism in the different populations, we performed a detailed analysis of genetic structure at both the individual and population levels. The whole-genome SNP panel identified several levels of population substructure in the set of examined cattle breeds. We further searched for spatial patterns of genetic diversity among these breeds under the recently developed spatial principal component analysis framework. Overall, such high throughput genotyping data confirmed a clear partitioning of the cattle genetic diversity into distinct breeds. The resulting complex historical origins associated with both natural and artificial selection have led to the differentiation of numerous different cattle breeds displaying a broad phenotypic variety over a short period of time. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pakistan" title="Pakistan">Pakistan</a>, <a href="https://publications.waset.org/abstracts/search?q=cattle" title=" cattle"> cattle</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20diversity" title=" genetic diversity"> genetic diversity</a>, <a href="https://publications.waset.org/abstracts/search?q=population%20structure" title=" population structure "> population structure </a> </p> <a href="https://publications.waset.org/abstracts/3168/population-structure-analysis-of-pakistani-indigenous-cattle-population-by-using-high-density-snp-array" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3168.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">620</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> An Automatic Bayesian Classification System for File Format Selection</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Roman%20Graf">Roman Graf</a>, <a href="https://publications.waset.org/abstracts/search?q=Sergiu%20Gordea"> Sergiu Gordea</a>, <a href="https://publications.waset.org/abstracts/search?q=Heather%20M.%20Ryan"> Heather M.

Its popularity is primarily because of its stability and robustness to model misspecification. However, the situation is different for the relative risk and risk difference, which are arguably easier to interpret and better suited to specific designs such as non-inferiority studies. So far, there is no equivalent, widely acceptable approach to estimate an adjusted relative risk and risk difference when conducting clinical trials. This is partly due to the lack of a comprehensive evaluation of available candidate methods. Methods/Approach: A simulation study is designed to evaluate the performance of relevant candidate methods to estimate relative risks to represent conditional and marginal estimation approaches. We consider the log-binomial, generalised linear models (GLM) with iteratively weighted least-squares (IWLS) and model-based standard errors (SE); log-binomial GLM with convex optimisation and model-based SEs; log-binomial GLM with convex optimisation and permutation tests; modified-Poisson GLM IWLS and robust SEs; log-binomial generalised estimation equations (GEE) and robust SEs; marginal standardisation and delta method SEs; and marginal standardisation and permutation test SEs. Independent and identically distributed datasets are simulated from a randomised controlled trial to evaluate these candidate methods. Simulations are replicated 10000 times for each scenario across all possible combinations of sample sizes (200, 1000, and 5000), outcomes (10%, 50%, and 80%), and covariates (ranging from -0.05 to 0.7) representing weak, moderate or strong relationships. Treatment effects (ranging from 0, -0.5, 1; on the log-scale) will consider null (H0) and alternative (H1) hypotheses to evaluate coverage and power in realistic scenarios. Performance measures (bias, mean square error (MSE), relative efficiency, and convergence rates) are evaluated across scenarios covering a range of sample sizes, event rates, covariate prognostic strength, and model misspecifications. Potential Results, Relevance & Impact: There are several methods for estimating unadjusted and adjusted relative risks. However, it is unclear which method(s) is the most efficient, preserves type-I error rate, is robust to model misspecification, or is the most powerful when adjusting for non-prognostic and prognostic covariates. GEE estimations may be biased when the outcome distributions are not from marginal binary data. Also, it seems that marginal standardisation and convex optimisation may perform better than GLM IWLS log-binomial. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=binary%20outcomes" title="binary outcomes">binary outcomes</a>, <a href="https://publications.waset.org/abstracts/search?q=statistical%20methods" title=" statistical methods"> statistical methods</a>, <a href="https://publications.waset.org/abstracts/search?q=clinical%20trials" title=" clinical trials"> clinical trials</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation%20study" title=" simulation study"> simulation study</a> </p> <a href="https://publications.waset.org/abstracts/154314/a-comparison-of-methods-for-estimating-dichotomous-treatment-effects-a-simulation-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154314.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">114</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">27</span> Quantitative Evaluation on Community Perceptions of Sanitation and Hygiene in Rural Guatemala </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Akudo%20Ejelonu">Akudo Ejelonu</a>, <a href="https://publications.waset.org/abstracts/search?q=Sarah%20Willig"> Sarah Willig</a>, <a href="https://publications.waset.org/abstracts/search?q=J.%20Anthony%20%20Sauder"> J.

Diarrheal diseases are preventable and improved access to latrines, hygiene education and clean water may improve sanitation by reducing the spread of disease. Objective: Between May 2015-January 2017, the University of Pennsylvania Chapter of Engineers Without Border (PennEWB) and local partners designed an intervention to reduce diarrheal disease by building pour flush latrines in 50 individual households and providing education on the importance of handwashing practice. Design/Methods: Through convenient sampling, we surveyed 45 households to evaluate the community’s knowledge of diarrheal disease, handwashing practices, and maintenance of the latrines. Results: 92% of the study participants experienced decrease of new cases of diarrheal disease after receiving a latrine. Only 11% washed their hands after defecating in the latrine. There was gap in understanding the health outcome of latrine sanitation and handwashing education. The respondents did not connect the reduction of diarrheal disease with latrine use and maintenance. Instead, they associated their motivation for latrine use with aesthetics, proximity to their home, ease and comfort, and reduction of shame. We recommend that PennEWB adopt UNICEF or WHO education on hand washing practice. Conclusion: Social interaction and social pressure drove the household use of latrines. The latrines are being valued and cleaned. The education that the residents received did not target norms and behaviors. Latrines could be used to create a new social norm that supports behavioral change. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diarrheal%20disease" title="diarrheal disease">diarrheal disease</a>, <a href="https://publications.waset.org/abstracts/search?q=latrine" title=" latrine"> latrine</a>, <a href="https://publications.waset.org/abstracts/search?q=open%20defecation" title=" open defecation"> open defecation</a>, <a href="https://publications.waset.org/abstracts/search?q=water" title=" water"> water</a>, <a href="https://publications.waset.org/abstracts/search?q=sanitation%20and%20hygiene" title=" sanitation and hygiene"> sanitation and hygiene</a> </p> <a href="https://publications.waset.org/abstracts/91524/quantitative-evaluation-on-community-perceptions-of-sanitation-and-hygiene-in-rural-guatemala" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/91524.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">157</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> A Bayesian Classification System for Facilitating an Institutional Risk Profile Definition</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Roman%20Graf">Roman Graf</a>, <a href="https://publications.waset.org/abstracts/search?q=Sergiu%20Gordea"> Sergiu Gordea</a>, <a href="https://publications.waset.org/abstracts/search?q=Heather%20M.%20Ryan"> Heather M.

The study aimed to explore and understand the factors affecting online health-seeking behaviors in middle-income class adults in Metro Manila. The study was conducted from March to April of 2021 with a sample size of 200 individuals aged 20 to 49 years old. The study was delivered via an online survey that used a questionnaire adapted from the research of Lee et al. (2015). Specifically, the survey consisted of three sections: assessing web-based health-seeking behaviors, consultation with health professionals, and participants' hesitancy to consult with physicians, which used a mix of a 5-point Likert-type scale with multiple responses and multiple-choice options. The results showed that the age and educational attainment of the respondents had a negative effect while presenting a positive effect of socio-economic status on health-seeking behavior. Lastly, there was a significant effect of participant’s hesitancy for professional consultation on their health-seeking behavior. The results gleaned from the study indicated that various individual and socio-economic factors might significantly affect one’s health-seeking behaviors. Although hesitancy had a significant effect on the spectrum of health-seeking behaviors, this does not imply that certain factors are specifically related to an individual’s tendency to seek health information. This information instead becomes essential in understanding the patient-physician relationship and giving patients a more holistic treatment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=health-seeking%20behavior" title="health-seeking behavior">health-seeking behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20information" title=" health information"> health information</a>, <a href="https://publications.waset.org/abstracts/search?q=Internet" title=" Internet"> Internet</a>, <a href="https://publications.waset.org/abstracts/search?q=physician%20consultation" title=" physician consultation"> physician consultation</a> </p> <a href="https://publications.waset.org/abstracts/138833/factors-affecting-online-health-seeking-behaviors-in-middle-income-class-filipino-adults" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/138833.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">216</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> Individual Differences and Paired Learning in Virtual Environments</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Patricia%20M.%20Boechler">Patricia M.

Three factors were of interest in relation to learning; 1) the influence of collaborative vs. independent conditions, 2) the influence of the spatial arrangement of the virtual environment (linear, random and clustered), and 3) the relationship of individual differences such as spatial skill, general computer experience and video game experience to learning. Students completed pretest measures of prior computer experience and prior spatial skill. Following the premeasure administration, students were given instruction to move through the virtual environment and study all the material within 10 information stations. In the collaborative condition, students proceeded in randomly assigned pairs, while in the independent condition they proceeded alone. After this learning phase, all students individually completed a multiple choice test to determine information retention. The overall results indicated that students in pairs did not perform any better or worse than independent students. As far as individual differences, only spatial ability predicted the performance of students. General computer experience and video game experience did not. Taking a closer look at the pairs and spatial ability, comparisons were made on pairs high/matched spatial ability, pairs low/matched spatial ability and pairs that were mismatched on spatial ability. The results showed that both high/matched pairs and mismatched pairs outperformed low/matched pairs. That is, if a pair had even one individual with strong spatial ability they would perform better than pairs with only low spatial ability individuals. This suggests that, in virtual environments, the specific individuals that are paired together are important for performance outcomes. The paper also includes a discussion of trends within the data that have implications for virtual environment education. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=avatar-based" title="avatar-based">avatar-based</a>, <a href="https://publications.waset.org/abstracts/search?q=virtual%20environment" title=" virtual environment"> virtual environment</a>, <a href="https://publications.waset.org/abstracts/search?q=paired%20learning" title=" paired learning"> paired learning</a>, <a href="https://publications.waset.org/abstracts/search?q=individual%20differences" title=" individual differences"> individual differences</a> </p> <a href="https://publications.waset.org/abstracts/106307/individual-differences-and-paired-learning-in-virtual-environments" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/106307.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">116</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> Proliferative Effect of Some Calcium Channel Blockers on the Human Embryonic Kidney Cell Line</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lukman%20Ahmad%20Jamil">Lukman Ahmad Jamil</a>, <a href="https://publications.waset.org/abstracts/search?q=Heather%20M.%20Wallace"> Heather M.

However, these associations were enmeshed with controversies in the absence of laboratory based studies to back up those claims. Aim: The aim of this study was to determine in mechanistic terms the association between the long-term administration of nifedipine and diltiazem and increased risk of developing cancer using the human embryonic kidney (HEK293) cell line. Methods: Cell counting using the Trypan blue dye exclusion and 3-4, 5-Dimethylthiazol-2-yl-2, 5-diphenyl-tetrazolium bromide (MTT) assays were used to investigate the effect of nifedipine and diltiazem on the growth pattern of HEK293 cells. Protein assay using modified Lowry method and analysis of intracellular polyamines concentration using Liquid Chromatography – Tandem Mass Spectrometry (LC-MS) were performed to ascertain the mechanism through which chronic use of nifedipine increases the risk of developing cancer. Results: Both nifedipine and diltiazem significantly increased the proliferation of HEK293 cells dose and time dependently. This proliferative effect after 24, 48 and 72-hour incubation period was observed at 0.78, 1.56 and 25 µM for nifedipine and 0.39, 1.56 and 25 µM for diltiazem, respectively. The increased proliferation of the cells was found to be statistically significantly (p<0.05). Furthermore, the increased proliferation of the cells induced by nifedipine was associated with the increase in the protein content and elevated intracellular polyamines concentration level. Conclusion: The chronic use of nifedipine is associated with increased proliferation of cells with concomitant elevation of polyamines concentration and elevated polyamine levels have been implicated in many malignant transformations and hence, these provide a possible explanation on the link between long term use of nifedipine and development of some human cancers. Further studies are needed to evaluate the cause of this association. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cancer" title="cancer">cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=nifedipine" title=" nifedipine"> nifedipine</a>, <a href="https://publications.waset.org/abstracts/search?q=polyamine" title=" polyamine"> polyamine</a>, <a href="https://publications.waset.org/abstracts/search?q=proliferation" title=" proliferation"> proliferation</a> </p> <a href="https://publications.waset.org/abstracts/77684/proliferative-effect-of-some-calcium-channel-blockers-on-the-human-embryonic-kidney-cell-line" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77684.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">198</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> Qualitative Needs Assessment for Development of a Smart Thumb Prosthetic</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Syena%20Moltaji">Syena Moltaji</a>, <a href="https://publications.waset.org/abstracts/search?q=Stephanie%20Posa"> Stephanie Posa</a>, <a href="https://publications.waset.org/abstracts/search?q=Sander%20Hitzig"> Sander Hitzig</a>, <a href="https://publications.waset.org/abstracts/search?q=Amanda%20Mayo"> Amanda Mayo</a>, <a href="https://publications.waset.org/abstracts/search?q=Heather%20Baltzer"> Heather Baltzer</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Purpose: To critically assess deficits following thumb amputation and delineate elements of an ideal thumb prosthesis from the end-user perspective. Methods: This was a qualitative study based on grounded theory. End-user stakeholder groups of thumb amputees and prosthetists were interviewed. Transcripts were reviewed whole first for familiarity. Data coding was then performed by two individual authors. Coded units were grouped by similarity and reviewed to reach a consensus. Codes were then analyzed for emergent themes by each author. A consensus meeting was held with all authors to finalize themes. Results: Three patients with traumatic thumb amputation and eight prosthetists were interviewed. Seven themes emerged. First was the significant impact of losing a thumb, in which codes of functional impact, mental impact, and occupational impact were included. The second theme was the unique nature of each thumb amputee, including goals, readiness for prosthesis, nature of the injury, and insurance. The third emergent theme was cost, surrounding government funding, insurability, and prosthetic pricing. The fourth theme was patient frustration, which included mismatches of prosthetic expectations and realities, activity limitations, and causes of devices abandonment. Themes five and six surrounded the strengths and weaknesses of current prosthetics, respectively. Theme seven was the ideal design for a thumb prosthetic, including abilities, suspension, and materials. Conclusions: Representative data from stakeholders mapped the current status of thumb prosthetics. Preferences for an ideal thumb prosthetic emerged, with suggestions for a simple, durable design. The ability to oppose, grasp and sense pressure was reported as functional priorities. Feasible cost and easy fitting emerged as systemic objectives. This data will be utilized in the development of a sensate thumb prosthetic. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=smart%20thumb" title="smart thumb">smart thumb</a>, <a href="https://publications.waset.org/abstracts/search?q=thumb%20prosthetic" title=" thumb prosthetic"> thumb prosthetic</a>, <a href="https://publications.waset.org/abstracts/search?q=sensate%20prosthetic" title=" sensate prosthetic"> sensate prosthetic</a>, <a href="https://publications.waset.org/abstracts/search?q=amputation" title=" amputation"> amputation</a> </p> <a href="https://publications.waset.org/abstracts/148325/qualitative-needs-assessment-for-development-of-a-smart-thumb-prosthetic" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148325.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">119</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">21</span> Prevalence and Associated Factors of Overweight and Obesity in Children with Intellectual Disability: A Cross-Sectional Study among Chinese Children</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jing-Jing%20Wang">Jing-Jing Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yang%20Gao"> Yang Gao</a>, <a href="https://publications.waset.org/abstracts/search?q=Heather%20H.%20M.%20Kwok"> Heather H.

A child with ID creates a wide set of challenges to the individual, family, and society, and overweight and obesity aggravate those challenges. People with ID have the right to attain optimal health like the rest of the population. They should be given priority to eliminate existing health inequities. Childhood obesity epidemic and associated factors among children, in general, has been well documented, while knowledge about overweight and obesity in children with ID is scarce. Methods: A cross-sectional study was conducted among 524 Chinese children with ID (males: 68.9%, mean age: 12.2 years) in Hong Kong in 2015. Children’s height and weight were measured at school. Parents, in the presence of their children, completed a self-administered questionnaire at home about the children’s physical activity (PA), eating habits, and sleep duration in a typical week as well as parenting practices regarding children’s eating and PA, and their socio-demographic characteristics. Multivariate logistic regression estimated the potential risk factors for children being overweight. Results: The prevalence of overweight and obesity in children with ID was 31.3%, which was higher than their general counterparts (18.7%-19.9%). Multivariate analyses revealed that the risk factors of overweight and obese in children with ID included: comorbidity with autism, the maternal side being overweight or obese, parenting practices with less pressure to eat more, children having shorter sleep duration, longer periods of sedentary behavior, and higher intake frequencies of sweetened food, fried food, and meats, fish, and eggs. Children born in other places, having snacks more frequently, and having irregular meals were also more likely to be overweight or obese, with marginal significance. Conclusions: Children with ID are more vulnerable to being overweight or obese than their typically developing counterparts. Identified risk factors in this study highlight a multifaceted approach to the involvement of parents as well as the modification of some children’s questionable behaviors to help them achieve a healthy weight. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=prevalence" title="prevalence">prevalence</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20factors" title=" risk factors"> risk factors</a>, <a href="https://publications.waset.org/abstracts/search?q=obesity" title=" obesity"> obesity</a>, <a href="https://publications.waset.org/abstracts/search?q=children%20with%20disability" title=" children with disability"> children with disability</a> </p> <a href="https://publications.waset.org/abstracts/90118/prevalence-and-associated-factors-of-overweight-and-obesity-in-children-with-intellectual-disability-a-cross-sectional-study-among-chinese-children" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/90118.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">135</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> Ecological and Cartographic Study of the Cork OAK of the Forest of Mahouna, North-Eastern of Algeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amina%20Beldjazia">Amina Beldjazia</a>, <a href="https://publications.waset.org/abstracts/search?q=Djamel%20Alatou"> Djamel Alatou</a>, <a href="https://publications.waset.org/abstracts/search?q=Khaled%20Missaoui"> Khaled Missaoui</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The forest of Mahouna is a part of the mountain range of the Tell Atlas in the northeast of Algeria. It is characterized by a significant biodiversity. The management of this resource requires thorough the understanding of the current state of the vegetation (inventories), degradation factors and ongoing monitoring of the various long-term ecological changes. Digital mapping is a very effective way to in-depth knowledge of natural resources. The realization of a vegetation map based on satellite images, aerial photographs and the use of geographic information system (GIS), shows large values results of the vegetation of the massif in the scientific view point (the development of a database of the different formations that exist on the site, ecological conditions) and economic (GIS facilitate our task of managing the various resources and diversity of the forest). The methodology is divided into three stages: the first involves an analysis of climate data (1988 to 2013); the second is to conduct field surveys (soil and phytoecological) during the months of June and July 2013 (10 readings), the third is based on the development of different themes and synthetic cards by software of GIS (ENVI 4.6 and 10 ARCMAP). The results show: cork oak covers an area of 1147 ha. Depending on the environmental conditions, it rests on sandstone and individualizes between 3 layers of vegetation from thermo-mediterranean (the North East part with 40ha), meso-Mediterranean (1061 ha) and finally the supra-Mediterranean (46ha ). The map shows the current actual state of the cork oak forest massif of Mahouna, it is an older forest (>150 years) where regeneration is absent because of several factors (fires, overgrazing, leaching, erosion, etc.). The cork oak is in the form of dense forest with Laburnum and heather as the dominant species. It may also present in open forest dominated by scrub species: Daphne gniduim, Erica arborea, Calycotome spinosa, Phillyrea angustifolia, Lavandula stoechas, Cistus salvifolius. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biodiversity" title="biodiversity">biodiversity</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental" title=" environmental"> environmental</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahouna" title=" Mahouna"> Mahouna</a>, <a href="https://publications.waset.org/abstracts/search?q=Cork%20oak" title=" Cork oak"> Cork oak</a> </p> <a href="https://publications.waset.org/abstracts/23427/ecological-and-cartographic-study-of-the-cork-oak-of-the-forest-of-mahouna-north-eastern-of-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23427.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">443</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> Mitigating Biofouling on Reverse Osmosis Membranes: Applying Greener Preservatives to Biofilm Treatment </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anna%20Curtin">Anna Curtin</a>, <a href="https://publications.waset.org/abstracts/search?q=Matthew%20%20Thibodeau"> Matthew Thibodeau</a>, <a href="https://publications.waset.org/abstracts/search?q=Heather%20Buckley"> Heather Buckley</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Water scarcity is characterized by a lack of access to clean and affordable drinking water, as well as water for hygienic and economic needs. The amount of people effected by water scarcity is expected to increase in the coming years due to climate change, population growth, and pollution, amongst other things. In response, scientists are pursuing cost effective drinking water treatment methods, often with a focus on alternative water sources. Desalination of seawater via reverse osmosis is one promising alternative method. Desalination of seawater via reverse osmosis, however, is limited significantly by biofouling of the filtration membrane. Biofouling is the buildup of microorganisms in a biofilm at the water-membrane interface. It clogs the membrane, decreasing the efficiency of filtration, consequently increasing operational and maintenance costs. Although effective, existing chemical treatment methods can damage the membrane, decreasing the lifespan of the membrane; create antibiotic resistance; and cause harm to humans and the environment if they pass through the membrane into the permeate. The current project focuses on applying safer preservatives used in home and personal care products to RO membranes to investigate the biofouling treatment efficacy. Currently, many of these safer preservatives have only been tested on cells in planktonic phase in suspension cultures, not on cells in biofilms. The results of suspension culture tests are not applicable to biofouling scenarios because organisms in planktonic phase in suspension cultures exhibit different morphological, chemical, and metabolic characteristics than those in a biofilm. Testing antifoulant efficacy of safer preservatives on biofilms will provide more applicable results to biofouling on RO membranes. To do this, biofilms will be grown on 96-well-plates and minimum inhibitory concentrations (MIC90) and log-reductions will be calculated for various safer preservatives. Results from these tests will be used to guide doses for tests of safer preservatives in a bench-scale RO system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=reverse%20osmosis" title="reverse osmosis">reverse osmosis</a>, <a href="https://publications.waset.org/abstracts/search?q=biofouling" title=" biofouling"> biofouling</a>, <a href="https://publications.waset.org/abstracts/search?q=preservatives" title=" preservatives"> preservatives</a>, <a href="https://publications.waset.org/abstracts/search?q=antimicrobial" title=" antimicrobial"> antimicrobial</a>, <a href="https://publications.waset.org/abstracts/search?q=safer%20alternative" title=" safer alternative"> safer alternative</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20chemistry" title=" green chemistry"> green chemistry</a> </p> <a href="https://publications.waset.org/abstracts/122887/mitigating-biofouling-on-reverse-osmosis-membranes-applying-greener-preservatives-to-biofilm-treatment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/122887.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">144</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18</span> Acceptance and Feasibility of Delivering an Evidence-based Digital Intervention for Palliative Care Education</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Areej%20Alosimi">Areej Alosimi</a>, <a href="https://publications.waset.org/abstracts/search?q=Heather%20Wharrad"> Heather Wharrad</a>, <a href="https://publications.waset.org/abstracts/search?q=Katharine%20Whittingham"> Katharine Whittingham</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Palliative care is a crucial element in nursing, especially with the steep increase in non-communicable diseases. Providing education in palliative care can help elevate the standards of care and address the growing need for it. However, palliative care has not been introduced into nursing curricula, specifically in Saudi Arabia, evidenced by students' inadequate understanding of the subject. Digital learning has been identified as a persuasive and effective method to improve education. The study aims to assess the feasibility and accessibility of implementing digital learning in palliative care education in Saudi Arabia by investigating the potential of delivering palliative care nurse education via distance learning. The study will utilize a sequential exploratory mixed-method approach. Phase one will entail identifying needs, developing a web-based program in phase two, and intervention implementation with a pre-post-test in phase three. Semi-structured interviews will be conducted to explore participant perceptions and thoughts regarding the intervention. Data collection will incorporate questionnaires and interviews with nursing students. Data analysis will use SPSS to analyze quantitative measurements and NVivo to analyze qualitative aspects. The study aims to provide insights into the feasibility of implementing digital learning in palliative care education. The results will serve as a foundation to investigate the effectiveness of e-learning interventions in palliative care education among nursing students. This study addresses a crucial gap in palliative care education, especially in nursing curricula, and explores the potential of digital learning to improve education. The results have broad implications for nursing education and the growing need for palliative care globally. The study assesses the feasibility and accessibility of implementing digital learning in palliative care education in Saudi Arabia. The research investigates whether palliative care nurse education can be effectively delivered through distance learning to improve students' understanding of the subject. The study's findings will lay the groundwork for a larger investigation on the efficacy of e-learning interventions in improving palliative care education among nursing students. The study can potentially contribute to the overall advancement of nursing education and the growing need for palliative care. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=undergraduate%20nursing%20students" title="undergraduate nursing students">undergraduate nursing students</a>, <a href="https://publications.waset.org/abstracts/search?q=E-Learning" title=" E-Learning"> E-Learning</a>, <a href="https://publications.waset.org/abstracts/search?q=Palliative%20care%20education" title=" Palliative care education"> Palliative care education</a>, <a href="https://publications.waset.org/abstracts/search?q=Knowledge" title=" Knowledge"> Knowledge</a> </p> <a href="https://publications.waset.org/abstracts/168627/acceptance-and-feasibility-of-delivering-an-evidence-based-digital-intervention-for-palliative-care-education" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168627.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">73</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> Understanding Trauma Informed Pedagogy in On-Line Education during Turbulent Times: A Mixed Methods Study in a Canadian Social Work Context</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Colleen%20McMillan">Colleen McMillan</a>, <a href="https://publications.waset.org/abstracts/search?q=Alice%20Schmidt-Hanbidge"> Alice Schmidt-Hanbidge</a>, <a href="https://publications.waset.org/abstracts/search?q=Beth%20Archer-Kuhn"> Beth Archer-Kuhn</a>, <a href="https://publications.waset.org/abstracts/search?q=Heather%20Boynton"> Heather Boynton</a>, <a href="https://publications.waset.org/abstracts/search?q=Judith%20Hughes"> Judith Hughes</a> </p> <p class="card-text"><strong>Abstract:</strong></p> It is well known that social work students enter the profession with higher scores of adverse childhood experiences (ACE). Add to that the fact that COVID-19 has forced higher education institutions to shift to online teaching and learning, where students, faculty and field educators in social work education have reported increased stressors as well as posing challenges in developing relationships with students and being able to identify mental health challenges including those related to trauma. This multi-institutional project included three Canadian post-secondary institutions at five sites (the University of Waterloo, the University of Calgary and the University of Manitoba) and partners; Desire To Learn (D2L), The Centre for Teaching Excellence at the University of Waterloo and the Taylor Institute for Teaching and Learning. A sequential mixed method research design was used. Survey data was collected from students, faculty and field education staff from the 3 universities using the Qualtrics Insight Platform, followed by virtual focus group data with students to provide greater clarity to the quantitative data. Survey data was analyzed using SPSS software, while focus group data was transcribed verbatim and organized with N-Vivo 12. Thematic analysis used line-by-line coding and constant comparative methods within and across focus groups. The following three objectives of the study were achieved: 1) Establish a Canadian baseline on trauma informed pedagogy and student experiences of trauma informed teaching in the online higher education environment during a pandemic; 2) Identify and document educator and student experiences of online learning regarding the ability to process trauma experiences; and, 3) Transfer the findings into a trauma informed pedagogical model for Social Work as a first step toward developing a universal trauma informed teaching model. The trauma informed pedagogy model would be presented in relation to the study findings. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=trauma%20informed%20pedagogy" title="trauma informed pedagogy">trauma informed pedagogy</a>, <a href="https://publications.waset.org/abstracts/search?q=higher%20education" title=" higher education"> higher education</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20work" title=" social work"> social work</a>, <a href="https://publications.waset.org/abstracts/search?q=mental%20health" title=" mental health"> mental health</a> </p> <a href="https://publications.waset.org/abstracts/165404/understanding-trauma-informed-pedagogy-in-on-line-education-during-turbulent-times-a-mixed-methods-study-in-a-canadian-social-work-context" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165404.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">90</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">16</span> Effect of Auraptene on the Enzymatic Glutathione Redox-System in Nrf2 Knockout Mice</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ludmila%20A.%20Gavriliuc">Ludmila A.

Nuclear factor erythroid 2-related factor (Nrf2) is an important regulator of genes induced by oxidative stress, such as glutathione S-transferases, heme oxygenase-1, and peroxiredoxin 1, by activating the antioxidant response element (ARE). Genetic and biochemical evidence has demonstrated that glutathione (GSH) and glutathione-dependent enzymes, glutathione reductase (GR), glutathione peroxidases (GPs), glutathione S-transferases (GSTs) are responsible for the control of intracellular reduction-oxidation status and participate in cellular adaptation to oxidative stress. The effect of Aur on the activity of GR, GPs (Se-GP and Se-iGP), and content of GSH in the liver, kidney, and spleen is insufficiently explored. Aim: Our goal was the examination of the Aur influence on the redox-system of GSH in Nrf2 wild type and Nrf2 knockout mice via activation of Nrf2 and ARE. Methods: Twenty female mice, 10 Nrf2 wild-type (WT) and 10 Nrf2 (-/-) knockout (KO), were bred and genotyped for our study. The activity of GR, Se-GP, Se-iGP, GST, G6PD, CytP450 reductase, catalase (Cat), and content of GSH were analyzed in the liver, kidney, and spleen using Spectrophotometry methods. The results of the specific activity of enzymes and the amount of GSH were analyzed with ANOVA and Spearman statistical methods. Results: Aur (200 mg/kg) treatment induced hepatic GST, GR, Se-GP activity and inhibited their activity in the spleen of mice, most likely via activation of the ARE through Nrf2. Activation in kidney Se-GP and G6PD by Aur is also controlled, apparently through Nrf2. Results of the non-parametric Spearman correlation analysis indicated the strong positive correlation between GR and G6PD only in the liver in WT control mice (r=+0.972; p < 0.005) and in the kidney KO control mice (r=+0.958; p < 0.005). The observed low content of GSH in the liver of KO mice indicated an increase in its participation in the neutralization of toxic substances with the absence of induction of GSH-dependent enzymes, such as GST, GR, Se-GP, and Se-iGP. Activation of CytP450 in kidney and spleen and Cat in the liver in KO mice probably revealed another regulatory mechanism for these enzymes. Conclusion: Thereby, obtained results testify that Aur can modulate the activity of genes and antioxidant enzymatic redox-system of GSH, responsible for the control of intracellular reduction-oxidation status. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=auraptene" title="auraptene">auraptene</a>, <a href="https://publications.waset.org/abstracts/search?q=glutathione" title=" glutathione"> glutathione</a>, <a href="https://publications.waset.org/abstracts/search?q=GST" title=" GST"> GST</a>, <a href="https://publications.waset.org/abstracts/search?q=Nrf2" title=" Nrf2"> Nrf2</a> </p> <a href="https://publications.waset.org/abstracts/133552/effect-of-auraptene-on-the-enzymatic-glutathione-redox-system-in-nrf2-knockout-mice" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/133552.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">15</span> Evaluation of Natural Waste Materials for Ammonia Removal in Biofilters</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=R.%20F.%20Vieira">R.

Information was collected about the substances and respective concentration in the surrounding atmosphere of some management plants. The main components which are associated with these unpleasant odours were identified: ammonia, hydrogen sulfide and mercaptans. The first is the most common and the one that presents the highest concentrations, reaching values of 700 mg/m3. Biofiltration, which involves simultaneously biodegradation, absorption and adsorption processes, is a sustainable technology for the treatment of these odour emissions when a natural packing material is used. The packing material should ideally be cheap, durable, and allow the maximum microbiological activity and adsorption/absorption. The presence of nutrients and water is required for biodegradation processes. Adsorption and absorption are enhanced by high specific surface area, high porosity and low density. The main purpose of this work is the exploitation of natural waste materials, locally available, as packing media: heather (Erica lusitanica), chestnut bur (from Castanea sativa), peach pits (from Prunus persica) and eucalyptus bark (from Eucalyptus globulus). Preliminary batch tests of ammonia removal were performed in order to select the most interesting materials for biofiltration, which were then characterized. The following physical and chemical parameters were evaluated: density, moisture, pH, buffer and water retention capacity. The determination of equilibrium isotherms and the adjustment to Langmuir and Freundlich models was also performed. Both models can fit the experimental results. Based both in the material performance as adsorbent and in its physical and chemical characteristics, eucalyptus bark was considered the best material. It presents a maximum adsorption capacity of 0.78±0.45 mol/kg for ammonia. The results from its characterization are: 121 kg/m3 density, 9.8% moisture, pH equal to 5.7, buffer capacity of 0.370 mmol H+/kg of dry matter and water retention capacity of 1.4 g H2O/g of dry matter. The application of natural materials locally available, with little processing, in biofiltration is an economic and sustainable alternative that should be explored. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ammonia%20removal" title="ammonia removal">ammonia removal</a>, <a href="https://publications.waset.org/abstracts/search?q=biofiltration" title=" biofiltration"> biofiltration</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20materials" title=" natural materials"> natural materials</a>, <a href="https://publications.waset.org/abstracts/search?q=odour%20control" title=" odour control"> odour control</a> </p> <a href="https://publications.waset.org/abstracts/24769/evaluation-of-natural-waste-materials-for-ammonia-removal-in-biofilters" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24769.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">369</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">14</span> Flood Mapping Using Height above the Nearest Drainage Model: A Case Study in Fredericton, NB, Canada</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Morteza%20Esfandiari">Morteza Esfandiari</a>, <a href="https://publications.waset.org/abstracts/search?q=Shabnam%20Jabari"> Shabnam Jabari</a>, <a href="https://publications.waset.org/abstracts/search?q=Heather%20MacGrath"> Heather MacGrath</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20Coleman"> David Coleman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Flood is a severe issue in different places in the world as well as the city of Fredericton, New Brunswick, Canada. The downtown area of Fredericton is close to the Saint John River, which is susceptible to flood around May every year. Recently, the frequency of flooding seems to be increased, especially after the fact that the downtown area and surrounding urban/agricultural lands got flooded in two consecutive years in 2018 and 2019. In order to have an explicit vision of flood span and damage to affected areas, it is necessary to use either flood inundation modelling or satellite data. Due to contingent availability and weather dependency of optical satellites, and limited existing data for the high cost of hydrodynamic models, it is not always feasible to rely on these sources of data to generate quality flood maps after or during the catastrophe. Height Above the Nearest Drainage (HAND), a state-of-the-art topo-hydrological index, normalizes the height of a basin based on the relative elevation along with the stream network and specifies the gravitational or the relative drainage potential of an area. HAND is a relative height difference between the stream network and each cell on a Digital Terrain Model (DTM). The stream layer is provided through a multi-step, time-consuming process which does not always result in an optimal representation of the river centerline depending on the topographic complexity of that region. HAND is used in numerous case studies with quite acceptable and sometimes unexpected results because of natural and human-made features on the surface of the earth. Some of these features might cause a disturbance in the generated model, and consequently, the model might not be able to predict the flow simulation accurately. We propose to include a previously existing stream layer generated by the province of New Brunswick and benefit from culvert maps to improve the water flow simulation and accordingly the accuracy of HAND model. By considering these parameters in our processing, we were able to increase the accuracy of the model from nearly 74% to almost 92%. The improved model can be used for generating highly accurate flood maps, which is necessary for future urban planning and flood damage estimation without any need for satellite imagery or hydrodynamic computations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=HAND" title="HAND">HAND</a>, <a href="https://publications.waset.org/abstracts/search?q=DTM" title=" DTM"> DTM</a>, <a href="https://publications.waset.org/abstracts/search?q=rapid%20floodplain" title=" rapid floodplain"> rapid floodplain</a>, <a href="https://publications.waset.org/abstracts/search?q=simplified%20conceptual%20models" title=" simplified conceptual models"> simplified conceptual models</a> </p> <a href="https://publications.waset.org/abstracts/112433/flood-mapping-using-height-above-the-nearest-drainage-model-a-case-study-in-fredericton-nb-canada" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/112433.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">151</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">13</span> Predictors of Quality of Life among Older Refugees Aging out of Place</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jonix%20Owino">Jonix Owino</a>, <a href="https://publications.waset.org/abstracts/search?q=Heather%20Fuller"> Heather Fuller</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Refugees flee from their home countries due to civil unrest, war, persecution and migrate to Western countries such as the United States in search of a safe haven. Transitioning into a new society and culture can be challenging, thereby affecting refugee’s quality of life and well-being in the host communities. Moreover, as individuals age, they experience physical, cognitive and socioemotional changes that may impact their quality of life. However, little is known about the predictors of quality of life among aging refugees. It is not clear how quality of life varies by age, that is, between midlife refugees in comparison to their older counterparts. In addition to age, other sociodemographic factors such as gender, socioeconomic status, or country of origin are likely to have differential associations to quality of life, yet research on such variations among older refugees is sparse. Thus the present study seeks to explore factors associated with quality of life by asking the following research questions: 1) Do sociodemographic factors (such as age and gender) predict quality of life among older refugees, 2) Is there an association between social integration and quality of life, and 3) Is there an association between migratory related experiences (such as post migratory adjustments) and quality of life. The present study recruited 90 refugees (primarily originating from Bhutan, Somalia, Burundi, and Sudan) aged 50 or older living in the US. The participants completed a structured questionnaire which assessed factors such as participant’s sociodemographic attributes (e.g., age, gender, length of residence in the US, country of origin, employment, level of education, and marital status), and validated measures of social integration, post-migration living difficulties, and quality of life. Preliminary results suggest sociodemographic variability in quality of life among these refugees. Further analyses will be conducted using hierarchical regression analyses to address the following hypotheses: first, it is hypothesized that quality of life will vary by age and gender such that younger refugees and men will report higher quality of life. Second, it is expected that refugees with greater levels of social integration will also report better quality of life. Finally, post-migration factors such as language barriers and family stress are hypothesized to predict poorer quality of life. Further results will be analyzed, including potential moderating effects of age and gender, and resulting findings will be interpreted and discussed. The findings from this study have potential implications for communities on how they can better support older refugees as well as develop social programs that can effectively cater to their well-being. Conclusions will be drawn and discussed in light of policies related to both aging and refugee migration within the context of the US. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aging%20out%20of%20place" title="aging out of place">aging out of place</a>, <a href="https://publications.waset.org/abstracts/search?q=migration" title=" migration"> migration</a>, <a href="https://publications.waset.org/abstracts/search?q=older%20refugees" title=" older refugees"> older refugees</a>, <a href="https://publications.waset.org/abstracts/search?q=quality%20of%20life" title=" quality of life"> quality of life</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20integration" title=" social integration "> social integration </a> </p> <a href="https://publications.waset.org/abstracts/118765/predictors-of-quality-of-life-among-older-refugees-aging-out-of-place" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/118765.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">100</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12</span> A Qualitative Study of Unmet Needs of Families of Children with Cerebral Palsy in Bangladesh</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Reshma%20Parvin%20Nuri">Reshma Parvin Nuri</a>, <a href="https://publications.waset.org/abstracts/search?q=Heather%20Michelle%20Aldersey"> Heather Michelle Aldersey</a>, <a href="https://publications.waset.org/abstracts/search?q=Setareh%20Ghahari"> Setareh Ghahari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objectives: Worldwide, it is well known that taking care of children with disabilities (CWD) can have a significant impact on the entire family unit. Over the last few decades, an increased number of studies have been conducted on families of CWD in higher income countries, and much of this research has identified family needs and strategies to meet those needs. However, family needs are incredibly under-studied in developing countries. Therefore, the aims of this study were to: (a) explore the needs of families of children with cerebral palsy (CP) in Bangladesh; (b) investigate how some of the family needs have been met and (c) identify the sources of supports that might help the families to meet their needs in the future. Methods: A face to face, semi-structured in-depth interview was conducted with 20 family members (12 mothers, 4 fathers, 1 sister, 2 grandmothers, and 1 aunt) who visited the Centre for the Rehabilitation of the Paralysed (CRP), Bangladesh between June and August 2016. Constant comparison method of grounded theory approach within the broader spectrum of qualitative study was used to analyze the data. Results: Participants identified five categories of needs: (a) financial needs, (b) access to disability-related services, (c) family and community cohesion, (d) informational needs, and (e) emotional needs. Participants overwhelmingly reported that financial need is their greatest family need. Participants noted that families encountered additional financial expenses for a child with CP, beyond what they would typically pay for their other children. Participants were seeing education as their non-primary need as they had no hope that their children would be physically able to go to school. Some participants also shared their needs for social inclusion and participation and receiving emotional support. Participants further expressed needs to receive information related to the child’s health condition and availability/accessibility of governmental support programs. Besides unmet needs, participants also highlighted that some of their needs have been met through formal and informal support systems. Formal support systems were mainly institution-based and run by non-governmental organizations, whereas participants identified informal support coming from family, friends and community members. Participants overwhelmingly reported that they receive little to no support from the government. However, participants identified the government as the key stakeholder who can play vital role in meeting their unmet needs. Conclusions: In the next phase of this research, the plan is to understand how the Government of the People’s Republic of Bangladesh is working to meet the needs of families of CWD. There is also need for further study on needs of families of children with conditions other than CP and those who live in the community and do not have access to the CRP Services. There is clear need to investigate ways to enable children with CP have better access to education in Bangladesh. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bangladesh" title="Bangladesh">Bangladesh</a>, <a href="https://publications.waset.org/abstracts/search?q=children%20with%20cerebral%20palsy" title=" children with cerebral palsy"> children with cerebral palsy</a>, <a href="https://publications.waset.org/abstracts/search?q=family%20needs" title=" family needs"> family needs</a>, <a href="https://publications.waset.org/abstracts/search?q=support" title=" support"> support</a> </p> <a href="https://publications.waset.org/abstracts/67376/a-qualitative-study-of-unmet-needs-of-families-of-children-with-cerebral-palsy-in-bangladesh" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67376.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">375</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">11</span> Resourcing Remote Rural Social Enterprises to Foster Resilience and Regional Development</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Heather%20Fulford">Heather Fulford</a>, <a href="https://publications.waset.org/abstracts/search?q=Melanie%20Liddell"> Melanie Liddell</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The recruitment and retention of high quality employees can prove to be challenging for social enterprises, particularly in some of the core business support functions such as marketing, communications, IT and finance. This holds true for social enterprises in urban contexts, where roles with more attractive remuneration in these business functions can often be found quite readily in the private sector. For social enterprises situated in rural locations, the challenges of staff recruitment and retention are even more acute. Such challenges can lead to a skills deficit in rural social enterprises, which can, at best, hinder their growth potential, and worse, jeopardise their chances of survival. This in turn, can have a negative impact on the sustainability and resilience of the surrounding rural community in which the social enterprise is located. The purpose of this paper is to report on aspects of a collaborative initiative established to stimulate innovation and business growth in remote rural businesses in Scotland. Launched in 2010, this initiative was designed to attract young students and graduates from the region to stay in the region upon completion of their studies, and to attract others from outside the region to re-locate there post-university. To facilitate this, SMEs in the region were offered wage subsidies to encourage them to recruit a student or graduate on a work placement for up to one year to participate in an innovation or business growth-oriented project. A number of the employers offering work placements were social enterprises. Through analysis of the placement project and role specifications devised by the participating social enterprises, an overview is provided of their business development needs and the skills they require to stimulate innovation and growth. Scrutiny of the reflective accounts compiled by the students and graduates at the close of their work placements highlights the benefits they derived from being able to put their academic knowledge and skills into action within a social enterprise. Examination of interviews conducted with a sample of placement employers reveals the contribution the students and graduates made during the business development projects with the social enterprises. The challenges of hosting such placements are also discussed. The paper concludes with indications of the lessons learned and an outline of the wider implications for other remote rural locations in which social enterprises play an important role in the local economy and life of the community. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=resilience" title="resilience">resilience</a>, <a href="https://publications.waset.org/abstracts/search?q=rural%20development" title=" rural development"> rural development</a>, <a href="https://publications.waset.org/abstracts/search?q=regeneration" title=" regeneration"> regeneration</a>, <a href="https://publications.waset.org/abstracts/search?q=regional%20development" title=" regional development"> regional development</a>, <a href="https://publications.waset.org/abstracts/search?q=recruitment" title=" recruitment"> recruitment</a>, <a href="https://publications.waset.org/abstracts/search?q=resource%20management" title=" resource management"> resource management</a>, <a href="https://publications.waset.org/abstracts/search?q=retention" title=" retention"> retention</a>, <a href="https://publications.waset.org/abstracts/search?q=remuneration" title=" remuneration"> remuneration</a> </p> <a href="https://publications.waset.org/abstracts/69346/resourcing-remote-rural-social-enterprises-to-foster-resilience-and-regional-development" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69346.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">315</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">10</span> Understanding Evidence Dispersal Caused by the Effects of Using Unmanned Aerial Vehicles in Active Indoor Crime Scenes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elizabeth%20Parrott">Elizabeth Parrott</a>, <a href="https://publications.waset.org/abstracts/search?q=Harry%20Pointon"> Harry Pointon</a>, <a href="https://publications.waset.org/abstracts/search?q=Frederic%20Bezombes"> Frederic Bezombes</a>, <a href="https://publications.waset.org/abstracts/search?q=Heather%20Panter"> Heather Panter </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Unmanned aerial vehicles (UAV’s) are making a profound effect within policing, forensic and fire service procedures worldwide. These intelligent devices have already proven useful in photographing and recording large-scale outdoor and indoor sites using orthomosaic and three-dimensional (3D) modelling techniques, for the purpose of capturing and recording sites during and post-incident. UAV’s are becoming an established tool as they are extending the reach of the photographer and offering new perspectives without the expense and restrictions of deploying full-scale aircraft. 3D reconstruction quality is directly linked to the resolution of captured images; therefore, close proximity flights are required for more detailed models. As technology advances deployment of UAVs in confined spaces is becoming more common. With this in mind, this study investigates the effects of UAV operation within active crimes scenes with regard to the dispersal of particulate evidence. To date, there has been little consideration given to the potential effects of using UAV’s within active crime scenes aside from a legislation point of view. Although potentially the technology can reduce the likelihood of contamination by replacing some of the roles of investigating practitioners. There is the risk of evidence dispersal caused by the effect of the strong airflow beneath the UAV, from the downwash of the propellers. The initial results of this study are therefore presented to determine the height of least effect at which to fly, and the commercial propeller type to choose to generate the smallest amount of disturbance from the dataset tested. In this study, a range of commercially available 4-inch propellers were chosen as a starting point due to the common availability and their small size makes them well suited for operation within confined spaces. To perform the testing, a rig was configured to support a single motor and propeller powered with a standalone mains power supply and controlled via a microcontroller. This was to mimic a complete throttle cycle and control the device to ensure repeatability. By removing the variances of battery packs and complex UAV structures to allow for a more robust setup. Therefore, the only changing factors were the propeller and operating height. The results were calculated via computer vision analysis of the recorded dispersal of the sample particles placed below the arm-mounted propeller. The aim of this initial study is to give practitioners an insight into the technology to use when operating within confined spaces as well as recognizing some of the issues caused by UAV’s within active crime scenes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dispersal" title="dispersal">dispersal</a>, <a
