Such failure includes leaks in above-ground storage tanks (AGST). The involvement of microorganisms in the corrosion process in AGST systems is often ignored, and this outlines the need to investigate the effect of microbial corrosion in oil and gas facilities. This study's methodology comprised gathering generated water samples from a nearby AGST oil facility that was operating, which were then equally divided into two batch reactors, 1 and 2. Each batch reactor was filled with five prepared X60 coupons using sterilized forceps. To provide nutrients for the microorganisms in batch reactor 1 during the test period, 2g of NPK 15- 15-15 fertilizer was added on a weekly basis. To kill the microorganisms and significantly lower their concentration in the generated water, 5ml of dissolved ozone (a biocide) with a 0.5ppm concentration was added to batch reactor 2. The weight loss measurement (WLM) was used to evaluate for corrosion. Coupons were removed from each batch reactor, and weight loss was measured at every interval of 336 hrs for 2016 hrs. The overall results obtained indicated that coupons from the batch 1 reactor showed a higher corrosion rate and higher mass loss, and this was due to the metabolic production of an aggressive compound in the medium. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=AGST" title="AGST">AGST</a>, <a href="https://publications.waset.org/abstracts/search?q=microbial%20corrosion" title=" microbial corrosion"> microbial corrosion</a>, <a href="https://publications.waset.org/abstracts/search?q=reactor" title=" reactor"> reactor</a>, <a href="https://publications.waset.org/abstracts/search?q=X60%20steel" title=" X60 steel"> X60 steel</a> </p> <a href="https://publications.waset.org/abstracts/165728/microbial-corrosion-on-oil-and-gas-facilities-a-case-study-of-oil-and-gas-facilities-in-the-niger-delta" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165728.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">84</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> Ethnic Entrepreneurships: Minority Ethnic Students in UiTM Sabah and UMS Perceptions towards Entrepreneurialism Business Interest </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lizinis%20Cassendra%20Frederick%20Dony">Lizinis Cassendra Frederick Dony</a>, <a href="https://publications.waset.org/abstracts/search?q=Dewi%20Binti%20Tajuddin"> Dewi Binti Tajuddin</a>, <a href="https://publications.waset.org/abstracts/search?q=Jirom%20Jeremy%20Frederick%20Dony"> Jirom Jeremy Frederick Dony</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrew%20Nicholas"> Andrew Nicholas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Unemployed graduates have become among the world major concerns lately. 70% of Malaysian graduates are jobless. Due to this concerns, this paper aims to identify major factors influencing Sabah minority ethnic favorable in the entrepreneurialism business interest. Hence, extensive introductory entrepreneurship syllabus clusters development beginning from the early childhood, primary, secondary and university students. This may induce interest appeal and to develop focus group of self-employment. The study focus on 7 indicators consist of demographic profiles variable (DP), social norms (SN), attitude (A), self-efficacy (SE) and business management skills (BMS) with reference to university students’ entrepreneurial intention. This study also partially mediates the relationship between product attractiveness (PA) and the minority ethnic entrepreneurialism business interest (MEEBI), by testifying their direct and indirect relationships. Hence, this study provides new perception towards improving the graduates’ characteristic, capabilities to exploit the business opportunities in the market. Furthermore, this paper will assess the relationship with the product attractiveness(PA) as a mediator. The study encompasses on the type of Sabah minority ethnic (ME) and nature of family own business (FOB) background with the 280 samples students in UiTM Sabah and UMS. The descriptive and random sampling method of research which revealed that majority of the respondents agreed that FOB and entrepreneurship education had positively influenced the ethnic students’ involvement in the entrepreneurial process and career development either full-time or part-time basis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Demographic%20profile%20%28DP%29" title="Demographic profile (DP)">Demographic profile (DP)</a>, <a href="https://publications.waset.org/abstracts/search?q=soci" title=" soci"> soci</a>, <a href="https://publications.waset.org/abstracts/search?q=unemployed%20graduates" title=" unemployed graduates"> unemployed graduates</a>, <a href="https://publications.waset.org/abstracts/search?q=Malaysian%20minority" title=" Malaysian minority"> Malaysian minority</a> </p> <a href="https://publications.waset.org/abstracts/30685/ethnic-entrepreneurships-minority-ethnic-students-in-uitm-sabah-and-ums-perceptions-towards-entrepreneurialism-business-interest" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30685.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">422</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 Effect of Gender and Resources on Entrepreneurial Activity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Frederick%20Nyakudya">Frederick Nyakudya</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we examine the relationship between human capital, personal wealth and social capital to explain the differential start-up rates between female and male entrepreneurs.

Lewis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> “Narratives of Slavery and the Culture of Play” examines how play is discussed in early African American literature by both men and women to illustrate ways that they negotiated the hierarchy and oppression of enslavement. Reading narratives categorized as “slave narratives,” including those written by Frederick Douglass, Harriet Jacobs, and Olaudah Equiano, through the lens of play theory offers an illuminated analysis of the significance of play culture in these texts. It then reads late nineteenth-century play culture (or absence thereof) portrayed in literature as a lens for more contemporary African American oral and literary culture. These discussions of social constructions through literature bridge analyses of African American-authored texts and create a larger conversation about print media as a tool of activism and resistance. This essay also contributes to a larger body of analysis of nineteenth-century African American culture through literature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=childhood" title="childhood">childhood</a>, <a href="https://publications.waset.org/abstracts/search?q=slavery" title=" slavery"> slavery</a>, <a href="https://publications.waset.org/abstracts/search?q=consciousness%20of%20play" title=" consciousness of play"> consciousness of play</a>, <a href="https://publications.waset.org/abstracts/search?q=19th%20century%20African%20American%20culture" title=" 19th century African American culture"> 19th century African American culture</a> </p> <a href="https://publications.waset.org/abstracts/29313/american-slavery-and-the-consciousness-of-play" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29313.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">502</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> Designing Affect-Aware Virtual Worlds for Marine Education Using Legacy Internet of Things Gaming Devices: Teaching through Fisheries and Conflicts</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jonathan%20Bishop">Jonathan Bishop</a>, <a href="https://publications.waset.org/abstracts/search?q=Kamal%20Bechkoum"> Kamal Bechkoum</a>, <a href="https://publications.waset.org/abstracts/search?q=Frederick%20Bishop"> Frederick Bishop</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study proposes a framework for marine education, leveraging legacy Internet of Things (IoT) gaming devices and affect-aware technology to create immersive virtual worlds.

This study investigated the incidence of Listeria monocytogenes in 80 RTE food sold in the formal (dairy and processed meat) and informal markets (vegetable salads, beef stew, and rice) of Johannesburg, South Africa. High Enterobacteriaceae, S. aureus, and E. coli counts were obtained, which ranged from 1.9-7.5 log CFU/g. Listeria monocytogenes microbial counts in the food samples ranged from 3.5-6.0 log colony forming unit per gram except in cooked rice. The Listeria monocytogenes isolates were identified using biochemical tests and confirmed with the Biolog identification system and PCR analyses. The percentage incidence for Listeria monocytogenes in ready to eat food was 12.5%. When Minimum Inhibitory Concentrations were under consideration, all disinfectants were effective against Listeria monocytogenes strains. For antimicrobial work, rates of resistance amongst the antibiotics ranged from 17-100%. Therefore, more effective preventive control strategies for Listeria monocytogenes are needed to reduce the prevalence of the pathogen in RTE food that is sold in Johannesburg. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Listeria%20monocytogenes" title="Listeria monocytogenes">Listeria monocytogenes</a>, <a href="https://publications.waset.org/abstracts/search?q=Listeria%20species" title=" Listeria species"> Listeria species</a>, <a href="https://publications.waset.org/abstracts/search?q=ready%20to%20eat%20food" title=" ready to eat food"> ready to eat food</a>, <a href="https://publications.waset.org/abstracts/search?q=sanitiser%20efficacy" title=" sanitiser efficacy"> sanitiser efficacy</a> </p> <a href="https://publications.waset.org/abstracts/114295/incidence-of-listeria-monocytogenes-in-ready-to-eat-food-sold-in-johannesburg-south-africa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/114295.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">166</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">31</span> Diaspora by Design; Jewish Refugee Architects and Wellington City</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Daniele%20Abreu%20e%20Lima">Daniele Abreu e Lima</a>, <a href="https://publications.waset.org/abstracts/search?q=Chloe%20Fitzpatrick"> Chloe Fitzpatrick</a> </p> <p class="card-text"><strong>Abstract:</strong></p> During the 1930s, New Zealand received a wave of refugees feeling from the impeding war and atrocities the Nazi regime was imposing on the German people. Among the hundreds of refugees were highly trained artists, architects and musicians who made a huge contribution to Wellington’s culture and identity. It is unfeasible to chronicle the impact of every Jewish refugee in the development of New Zealand arts scene. But it is possible to choose a number of them and analyse their contribution to NZ culture. This research aims to bring to light the reception and life of five influential Jewish architects; Helmut Einhorn, Ernst Plischke, Frederick Neumann, Henry Kulka, and Maximillian Rosenfeld. Each had a key role in influencing New Zealand architectural landscape and the modernization of the country. Before coming to New Zealand, these five architects lived different lives working all over Europe, from Paris through to Moscow. In common, apart from their ethnicity, they had led cultured lives where they were culturally and politically active. This research looks at how much their individual contributions helped to transform the architectural scene in New Zealand but also in the amount of cultural and religious renunciation they had to endure to be accepted in the country. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jewish%20Refugee%20architects" title="Jewish Refugee architects">Jewish Refugee architects</a>, <a href="https://publications.waset.org/abstracts/search?q=modern%20architecture" title=" modern architecture"> modern architecture</a>, <a href="https://publications.waset.org/abstracts/search?q=World%20War%202" title=" World War 2"> World War 2</a>, <a href="https://publications.waset.org/abstracts/search?q=New%20Zealand" title=" New Zealand"> New Zealand</a> </p> <a href="https://publications.waset.org/abstracts/185320/diaspora-by-design-jewish-refugee-architects-and-wellington-city" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185320.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">55</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> A Study on Economic Impacts of Entrepreneurial Firms and Self-Employment: Minority Ethnics in Putatan, Penampang, Inanam, Menggatal, Uitm, Tongod, Sabah, Malaysia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lizinis%20Cassendra%20Frederick%20Dony">Lizinis Cassendra Frederick Dony</a>, <a href="https://publications.waset.org/abstracts/search?q=Jirom%20Jeremy%20Frederick%20Dony"> Jirom Jeremy Frederick Dony</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrew%20Nicholas"> Andrew Nicholas</a>, <a href="https://publications.waset.org/abstracts/search?q=Dewi%20Binti%20Tajuddin"> Dewi Binti Tajuddin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Starting and surviving a business is influenced by various entrepreneurship socio-economics activities.

The business environment among the minority ethnics are influenced with the business sentiment competition. The literature on ethnic entrepreneurship recognizes two main type entrepreneurships: the middleman and enclave entrepreneurs. According to Adam Smith,3 there are evidently some principles disposition to admire and maintain the distinction business rank status and cause most universal business sentiments. Due to credit barriers competition, the minority ethnics are losing the business market and since 2014, many illegal immigrants have been found to be using permits of the locals to operate businesses in Malaysia.4 The development of small business entrepreneurship among the minority ethnics in Sabah evidenced based variety of complex perception and differences concepts. The studies also confirmed the effects of heterogeneity on group decision and thinking caused partly by excessive pre-occupation with maintaining cohesiveness and the presence of cultural diversity in groups should reduce its probability.5 The researchers proposed that there are seven success determinants particularly to determine the involvement of minority ethnics comparing to the involvement of the immigrants in Sabah. Although, (SMEs) have always been considered the backbone of the economy development, the minority ethnics are often categorized it as the “second-choice.’ The study showed that illegal immigrants entrepreneur imposed a burden on Sabahan social programs as well as the prison, court and health care systems. The tension between the need for cheap labor and the impulse to protect Malaysian in Sabah workers, entrepreneurs and taxpayers, among the subjects discussed in this study. This is clearly can be advantages and disadvantages to the Sabah economic development. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=entrepreneurial%20firms" title="entrepreneurial firms">entrepreneurial firms</a>, <a href="https://publications.waset.org/abstracts/search?q=self-employed" title=" self-employed"> self-employed</a>, <a href="https://publications.waset.org/abstracts/search?q=immigrants" title=" immigrants"> immigrants</a>, <a href="https://publications.waset.org/abstracts/search?q=minority%20ethnic" title=" minority ethnic"> minority ethnic</a>, <a href="https://publications.waset.org/abstracts/search?q=economic%20impacts" title=" economic impacts"> economic impacts</a> </p> <a href="https://publications.waset.org/abstracts/31264/a-study-on-economic-impacts-of-entrepreneurial-firms-and-self-employment-minority-ethnics-in-putatan-penampang-inanam-menggatal-uitm-tongod-sabah-malaysia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31264.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">413</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">29</span> Innocence Compensation: Motions to Strike and Dismiss to Forestall Financial Recovery</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Myles%20Frederick%20McLellan">Myles Frederick McLellan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> When errors in the criminal justice process lead to wrongful convictions and miscarriages of justice, it falls upon the State to make reparation for the egregious harms brought to innocent individuals. Of all the remedies available to seek compensation, private and public law litigation against the police and prosecution services is the most widely used. Unfortunately, all levels of court including the Supreme Court of Canada have explicitly endorsed the prospect of striking out or dismissing these claims at the outset on an expedited basis. The burden on agents of the State as defendants to succeed on motions for such relief is so low that very few actions will survive to give an innocent accused his or her day in court. This paper will be a quantitative and qualitative analysis on the occurrence and success of motions to strike and dismiss to forestall financial recovery for the damage caused when a criminal investigation and prosecution goes wrong. This paper will also include a comparative component on the private law systems at common law (e.g. USA, UK, Australia and New Zealand) with respect to the availability of a similar process to pre-emptively terminate litigation for the recovery of compensation to an innocent individual. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=compensation" title="compensation">compensation</a>, <a href="https://publications.waset.org/abstracts/search?q=innocence" title=" innocence"> innocence</a>, <a href="https://publications.waset.org/abstracts/search?q=miscarriages%20of%20justice" title=" miscarriages of justice"> miscarriages of justice</a>, <a href="https://publications.waset.org/abstracts/search?q=wrongful%20convictions" title=" wrongful convictions"> wrongful convictions</a> </p> <a href="https://publications.waset.org/abstracts/98245/innocence-compensation-motions-to-strike-and-dismiss-to-forestall-financial-recovery" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98245.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">140</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">28</span> An Automatic Model Transformation Methodology Based on Semantic and Syntactic Comparisons and the Granularity Issue Involved</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tiexin%20Wang">Tiexin Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Sebastien%20Truptil"> Sebastien Truptil</a>, <a href="https://publications.waset.org/abstracts/search?q=Frederick%20Benaben"> Frederick Benaben</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Model transformation, as a pivotal aspect of Model-driven engineering, attracts more and more attentions both from researchers and practitioners. Many domains (enterprise engineering, software engineering, knowledge engineering, etc.) use model transformation principles and practices to serve to their domain specific problems; furthermore, model transformation could also be used to fulfill the gap between different domains: by sharing and exchanging knowledge. Since model transformation has been widely used, there comes new requirement on it: effectively and efficiently define the transformation process and reduce manual effort that involved in. This paper presents an automatic model transformation methodology based on semantic and syntactic comparisons, and focuses particularly on granularity issue that existed in transformation process. Comparing to the traditional model transformation methodologies, this methodology serves to a general purpose: cross-domain methodology. Semantic and syntactic checking measurements are combined into a refined transformation process, which solves the granularity issue. Moreover, semantic and syntactic comparisons are supported by software tool; manual effort is replaced in this way. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=automatic%20model%20transformation" title="automatic model transformation">automatic model transformation</a>, <a href="https://publications.waset.org/abstracts/search?q=granularity%20issue" title=" granularity issue"> granularity issue</a>, <a href="https://publications.waset.org/abstracts/search?q=model-driven%20engineering" title=" model-driven engineering"> model-driven engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=semantic%20and%20syntactic%20comparisons" title=" semantic and syntactic comparisons"> semantic and syntactic comparisons</a> </p> <a href="https://publications.waset.org/abstracts/27878/an-automatic-model-transformation-methodology-based-on-semantic-and-syntactic-comparisons-and-the-granularity-issue-involved" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27878.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">397</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> Internal Product Management: The Key to Achieving Digital Maturity and Business Agility for Manufacturing IT Organizations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Frederick%20Johnson">Frederick Johnson</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Product management has a long and well-established history within the consumer goods industry, despite being one of the most obscure aspects of brand management. Many global manufacturing organizations are now opting for external cloud-based Manufacturing Execution Systems (MES) to replace costly and outdated monolithic MES solutions. Other global manufacturing leaders are restructuring their organizations to support human-centered values, agile methodologies, and fluid operating principles. Still, industry-leading organizations struggle to apply the appropriate framework for managing evolving external MES solutions as internal "digital products." Product management complements these current trends in technology and philosophical thinking in the market. This paper discusses the central problems associated with adopting product management processes by analyzing its traditional theories and characteristics. Considering these ideas, the article then constructs a translated internal digital product management framework by combining new and existing approaches and principles. The report concludes by demonstrating the framework's capabilities and potential effectiveness in achieving digital maturity and business agility within a manufacturing environment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=internal%20product%20management" title="internal product management">internal product management</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20transformation" title=" digital transformation"> digital transformation</a>, <a href="https://publications.waset.org/abstracts/search?q=manufacturing%20information%20technology" title=" manufacturing information technology"> manufacturing information technology</a>, <a href="https://publications.waset.org/abstracts/search?q=manufacturing%20execution%20systems" title=" manufacturing execution systems"> manufacturing execution systems</a> </p> <a href="https://publications.waset.org/abstracts/135214/internal-product-management-the-key-to-achieving-digital-maturity-and-business-agility-for-manufacturing-it-organizations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/135214.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">26</span> Investigating the Behavior of Water Shortage Indices for Performance Evaluation of a Water Resources System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Frederick%20N.%20F.%20Chou">Frederick N.

The need for improvements in reliable water supply systems is urgent with the increasing living standards of regions. In this study, a suitable shortage index capable of multi-aspect description - frequency, magnitude, and duration - is adopted to more accurately describe the characteristics of a shortage situation. The values of the index were determined to cope with the increasing need for reliability. There are four reservoirs in series located on the Be River of the Dong Nai River Basin in Southern Vietnam. The primary purpose of the three upstream reservoirs is hydropower generation while the primary purpose of the fourth is water supply. A compromise between hydropower generation and water supply can be negotiated for these four reservoirs to reduce the severity of water shortages. A generalized water allocation model was applied to simulate the water supply, and hydropower generation of various management alternatives and the system’s reliability was evaluated using the adopted multiple shortage indices. Modifying management policies of water resources using data-based indexes can improve the reliability of water supply. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cascade%20reservoirs" title="cascade reservoirs">cascade reservoirs</a>, <a href="https://publications.waset.org/abstracts/search?q=hydropower" title=" hydropower"> hydropower</a>, <a href="https://publications.waset.org/abstracts/search?q=shortage%20index" title=" shortage index"> shortage index</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20supply" title=" water supply"> water supply</a> </p> <a href="https://publications.waset.org/abstracts/84967/investigating-the-behavior-of-water-shortage-indices-for-performance-evaluation-of-a-water-resources-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84967.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">269</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">25</span> Various Models of Quality Management Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mehrnoosh%20Askarizadeh">Mehrnoosh Askarizadeh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> People, process and IT are the most important assets of any organization. Optimal utilization of these resources has been the question of research in business for many decades. The business world have responded by inventing various methodologies that can be used for addressing problems of quality improvement, efficiency of processes, continuous improvement, reduction of waste, automation, strategy alignments etc. Some of these methodologies can be commonly called as Business Process Quality Management methodologies (BPQM). In essence, the first references to the process management can be traced back to Frederick Taylor and scientific management. Time and motion study was addressed to improvement of manufacturing process efficiency. The ideas of scientific management were in use for quite a long period until more advanced quality management techniques were developed in Japan and USA. One of the first prominent methods had been Total Quality Management (TQM) which evolved during 1980’s. About the same time, Six Sigma (SS) originated at Motorola as a separate method. SS spread and evolved; and later joined with ideas of Lean manufacturing to form Lean Six Sigma. In 1990’s due to emerging IT technologies, beginning of globalization, and strengthening of competition, companies recognized the need for better process and quality management. Business Process Management (BPM) emerged as a novel methodology that has taken all this into account and helped to align IT technologies with business processes and quality management. In this article we will study various aspects of above mentioned methods and identified their relations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=e-process" title="e-process">e-process</a>, <a href="https://publications.waset.org/abstracts/search?q=quality" title=" quality"> quality</a>, <a href="https://publications.waset.org/abstracts/search?q=TQM" title=" TQM"> TQM</a>, <a href="https://publications.waset.org/abstracts/search?q=BPM" title=" BPM"> BPM</a>, <a href="https://publications.waset.org/abstracts/search?q=lean" title=" lean"> lean</a>, <a href="https://publications.waset.org/abstracts/search?q=six%20sigma" title=" six sigma"> six sigma</a>, <a href="https://publications.waset.org/abstracts/search?q=CPI" title=" CPI"> CPI</a>, <a href="https://publications.waset.org/abstracts/search?q=information%20technology" title=" information technology"> information technology</a>, <a href="https://publications.waset.org/abstracts/search?q=management" title=" management"> management</a> </p> <a href="https://publications.waset.org/abstracts/36755/various-models-of-quality-management-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36755.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">440</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> GPRS Based Automatic Metering System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Constant%20Akama">Constant Akama</a>, <a href="https://publications.waset.org/abstracts/search?q=Frank%20Kulor"> Frank Kulor</a>, <a href="https://publications.waset.org/abstracts/search?q=Frederick%20Agyemang"> Frederick Agyemang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> All over the world, due to increasing population, electric power distribution companies are looking for more efficient ways of reading electricity meters. In Ghana, the prepaid metering system was introduced in 2007 to replace the manual system of reading which was fraught with inefficiencies. However, the prepaid system in Ghana is not capable of integration with online systems such as e-commerce platforms and remote monitoring systems. In this paper, we present a design framework for an automatic metering system that can be integrated with e-commerce platforms and remote monitoring systems. The meter was designed using ADE 7755 which reads the energy consumption and the reading is processed by a microcontroller connected to Sim900 General Packet Radio Service module containing a GSM chip provisioned with an Access Point Name. The system also has a billing server and a management server located at the premises of the utility company which communicate with the meter over a Virtual Private Network and GPRS. With this system, customers can buy credit online and the credit will be transferred securely to the meter. Also, when a fault is reported, the utility company can log into the meter remotely through the management server to troubleshoot the problem. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=access%20point%20name" title="access point name">access point name</a>, <a href="https://publications.waset.org/abstracts/search?q=general%20packet%20radio%20service" title=" general packet radio service"> general packet radio service</a>, <a href="https://publications.waset.org/abstracts/search?q=GSM" title=" GSM"> GSM</a>, <a href="https://publications.waset.org/abstracts/search?q=virtual%20private%20network" title=" virtual private network"> virtual private network</a> </p> <a href="https://publications.waset.org/abstracts/7470/gprs-based-automatic-metering-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7470.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">300</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> Physics of Decision for Polling Place Management: A Case Study from the 2020 USA Presidential Election</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nafe%20Moradkhani">Nafe Moradkhani</a>, <a href="https://publications.waset.org/abstracts/search?q=Frederick%20Benaben"> Frederick Benaben</a>, <a href="https://publications.waset.org/abstracts/search?q=Benoit%20Montreuil"> Benoit Montreuil</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Vatankhah%20Barenji"> Ali Vatankhah Barenji</a>, <a href="https://publications.waset.org/abstracts/search?q=Dima%20Nazzal"> Dima Nazzal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the context of the global pandemic, the practical management of the 2020 presidential election in the USA was a strong concern. To anticipate and prepare for this election accurately, one of the main challenges was to confront (i) forecasts of voter turnout, (ii) capacities of the facilities and, (iii) potential configuration options of resources. The approach chosen to conduct this anticipative study consists of collecting data about forecasts and using simulation models to work simultaneously on resource allocation and facility configuration of polling places in Fulton County, Georgia’s largest county. A polling place is a dedicated facility where voters cast their ballots in elections using different devices. This article presents the results of the simulations of such places facing pre-identified potential risks. These results are oriented towards the efficiency of these places according to different criteria (health, trust, comfort). Then a dynamic framework is introduced to describe risks as physical forces perturbing the efficiency of the observed system. Finally, the main benefits and contributions resulting from this simulation campaign are presented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=performance" title="performance">performance</a>, <a href="https://publications.waset.org/abstracts/search?q=decision%20support" title=" decision support"> decision support</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=artificial%20intelligence" title=" artificial intelligence"> artificial intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20management" title=" risk management"> risk management</a>, <a href="https://publications.waset.org/abstracts/search?q=election" title=" election"> election</a>, <a href="https://publications.waset.org/abstracts/search?q=pandemics" title=" pandemics"> pandemics</a>, <a href="https://publications.waset.org/abstracts/search?q=information%20system" title=" information system"> information system</a> </p> <a href="https://publications.waset.org/abstracts/136683/physics-of-decision-for-polling-place-management-a-case-study-from-the-2020-usa-presidential-election" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/136683.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">22</span> Beyond the Dust: Workers' Perspectives on Enhancing Silica Exposure Control in Tunnel Construction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Frederick%20Anlimah">Frederick Anlimah</a>, <a href="https://publications.waset.org/abstracts/search?q=Vinod%20Gopaldasani"> Vinod Gopaldasani</a>, <a href="https://publications.waset.org/abstracts/search?q=Catherine%20MacPhail"> Catherine MacPhail</a>, <a href="https://publications.waset.org/abstracts/search?q=Brian%20Davies"> Brian Davies</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The construction industry, particularly tunnel construction, exposes workers to respirable crystalline silica (RCS), which can cause incurable illnesses such as silicosis and lung cancer. Despite various control measures, exposures remain inadequately controlled. This research aimed to examine what workers on a tunnelling project in Australia think should be done to reduce exposure to dust to protect them from RCS exposure. A qualitative research approach consisting of interviews and focus group discussions was employed for this research. The preliminary analysis of the data reveals a diverse array of solutions proposed to address the different sociotechnical factors that present challenges for effectively reducing dust exposure. Solutions are proposed to address challenges such as cost, time pressure, low-risk perception, inadequate awareness, inadequate enforcement and compliance with personal protective equipment. The findings highlight the need to make dust control a level playing field for all contractors during the bidding process, with more collaboration and enforcement after the signing of contracts. The research highlights that although improvements have been made in the past years regarding dust controls, many opportunities exist to reduce worker exposure to RCS. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tunnel" title="tunnel">tunnel</a>, <a href="https://publications.waset.org/abstracts/search?q=respirable%20crystalline%20silica" title=" respirable crystalline silica"> respirable crystalline silica</a>, <a href="https://publications.waset.org/abstracts/search?q=RCS" title=" RCS"> RCS</a>, <a href="https://publications.waset.org/abstracts/search?q=dust%20exposure" title=" dust exposure"> dust exposure</a>, <a href="https://publications.waset.org/abstracts/search?q=personal%20protective%20equipment" title=" personal protective equipment"> personal protective equipment</a>, <a href="https://publications.waset.org/abstracts/search?q=worker%20perspectives" title=" worker perspectives"> worker perspectives</a> </p> <a href="https://publications.waset.org/abstracts/177375/beyond-the-dust-workers-perspectives-on-enhancing-silica-exposure-control-in-tunnel-construction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/177375.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">80</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> Field Trips inside Digital Game Environments</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amani%20Alsaqqaf">Amani Alsaqqaf</a>, <a href="https://publications.waset.org/abstracts/search?q=Frederick%20W.%20B.%20Li"> Frederick W.

Virtual field trips (VFTs) in game environments provide FT experience based on the experiential learning theory (ELT). A conceptual framework for designing virtual field trip games (VFTGs) is developed with an aim to support game designers and educators to produce an effective FT experience where technology would enhance education. The conceptual framework quantifies ELT as an internal economy to link learning elements to game mechanics such as feedback loops which leads to facilitating VFTGs design and implementation. This study assesses the conceptual framework for designing VFTGs by investigating the possibility of applying immersive VFTGs in a secondary classroom and compare them with traditional learning that uses video clips and PowerPoint slides from the viewpoint of students’ perceived motivation, presence, and learning. The assessment is achieved by evaluating the learning performance and learner experience of a prototype VFT game, Island of Volcanoes. A quasi-experiment was conducted with 60 secondary school students. The findings of this study are that the VFTG enhanced learning performance to a better level than did the traditional way of learning, and in addition, it provided motivation and a general feeling of presence in the VFTG environment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=conceptual%20framework" title="conceptual framework">conceptual framework</a>, <a href="https://publications.waset.org/abstracts/search?q=game-based%20learning" title=" game-based learning"> game-based learning</a>, <a href="https://publications.waset.org/abstracts/search?q=game%20design" title=" game design"> game design</a>, <a href="https://publications.waset.org/abstracts/search?q=virtual%20field%20trip%20game" title=" virtual field trip game"> virtual field trip game</a> </p> <a href="https://publications.waset.org/abstracts/138070/field-trips-inside-digital-game-environments" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/138070.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">235</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> Racism in Drug Policies: A Report on United States Legislation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Frederick%20Monyepao">Frederick Monyepao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Crack cocaine first appeared on the scene in the form of cocaine freebasing in the late 1970s. Stockbrokers, investment bankers, rock stars, Hollywood elites, and a few pro athletes were regular users of the substance. As criminogenic factors associated with substance abuse began to surface, congress passed new legislation. The laws led to the increase of health coverage insurances and the expansion of hospitals. By the mid-1980s, crack use spread into America's inner cities among impoverished African Americans and Latinos. While substance abuse increased among minority communities, legislation pertaining to substance abuse evolved. The prison industry also expanded the number of cells available. A qualitative approach was taken, drawing from a range secondary sources for contextual analysis. This paper traces out the continued marginalisation and racist undertones towards minorities as perpetuated by certain drug policies. It was discovered that the new legislation on crack was instrumental in the largest incarcerations the United States ever faced. Drug offenders increased in prisons eightfold from 1986 to 2000. The paper concludes that American drug control policies are consistently irrational and ineffective when measured by levels of substance use and abuse. On the contrary, these policies have been successful as agents of social control in maintaining the stratification patterns of racial/ethnic minorities and women. To move beyond prohibition, radical law and policy reform may require a change in narratives on substance use. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=crack" title="crack">crack</a>, <a href="https://publications.waset.org/abstracts/search?q=drug%20policy" title=" drug policy"> drug policy</a>, <a href="https://publications.waset.org/abstracts/search?q=minorities" title=" minorities"> minorities</a>, <a href="https://publications.waset.org/abstracts/search?q=racism" title=" racism"> racism</a>, <a href="https://publications.waset.org/abstracts/search?q=substance%20abuse" title=" substance abuse"> substance abuse</a> </p> <a href="https://publications.waset.org/abstracts/69046/racism-in-drug-policies-a-report-on-united-states-legislation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69046.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">291</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> Antimicrobial, Antioxidant and Cytotoxicity Properties of Some Selected Wild Edible Fruits Used Traditionally as a Source of Food</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Thilivhali%20Emmanuel%20Tshikalange">Thilivhali Emmanuel Tshikalange</a>, <a href="https://publications.waset.org/abstracts/search?q=Darky%20Cheron%20Modishane"> Darky Cheron Modishane</a>, <a href="https://publications.waset.org/abstracts/search?q=Frederick%20Tawi%20Tabit"> Frederick Tawi Tabit</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The fruit pulp extracts of twelve selected ethnobotanical wild edible fruits from Mutale local municipality in Venda (Limpopo Province, South Africa) were investigated for their antimicrobial, antioxidant and cytotoxicity activities. Methanol extracts were prepared and tested against six micro-organisms (Salmonella typhi, Streptococcus pyogenes, Bacillus cereus, Klebsiella pneumoniae, Prevotella intermedia and Candida albicans). The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) were determined using the micro-dilution method, while for antioxidant activity the 2,2-diphenyl-1-picrylhydrazyl method was used. Of the 12 extracts tested, Adonsonia digitata, Berchemia discolor, Manilkara mochisia, Xanthocercis zambesiaca, Landolphia kirkii and Garcinia livingstonei showed antimicrobial activity, with MIC values ranging from 12.5 to 0.4 mg/ml. Gram negative bacteria were more resistant to the extracts in comparison to Gram positive bacteria. Antioxidant activity was only detected in Adonsonia digitata extract and the IC50 (substrate concentration to produce 50% reduction) was found to be 16.18µg/ml. The cytotoxicity of the extracts that showed antimicrobial and antioxidant activities was also determined. All plant extracts tested were non-toxic against human kidney cells (HEK293), with IC50 values of >400 µg/ml. The results presented in this study provide support to some traditional uses of wild edible fruits. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antimicrobial" title="antimicrobial">antimicrobial</a>, <a href="https://publications.waset.org/abstracts/search?q=antioxidant" title=" antioxidant"> antioxidant</a>, <a href="https://publications.waset.org/abstracts/search?q=cytotoxicity" title=" cytotoxicity"> cytotoxicity</a>, <a href="https://publications.waset.org/abstracts/search?q=ethnobotanical" title=" ethnobotanical"> ethnobotanical</a>, <a href="https://publications.waset.org/abstracts/search?q=fruits" title=" fruits"> fruits</a> </p> <a href="https://publications.waset.org/abstracts/46586/antimicrobial-antioxidant-and-cytotoxicity-properties-of-some-selected-wild-edible-fruits-used-traditionally-as-a-source-of-food" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46586.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">392</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> Pull String to Stop: Public Utility Vehicle Modernization Program</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Frederick%20Kobe%20O.%20Obar">Frederick Kobe O.

This study determined the impact of the Public Utility Vehicle Modernization Program on San Fernando City, La Union's jeepney drivers, interviewing six individuals, three with traditional vehicles and three with modernized units. This study used a descriptive qualitative research design and employed purposive sampling to select the six participants suited for the study, who were then subjected to a semi-structured face-to-face interview. The gathered data was then analyzed through thematic analysis. The findings highlighted evidence that the jeepney drivers experienced abrupt and prevailing changes in their routine and in their everyday work. This study concludes that while the sentiment of the program was appreciated, it has changed the environment for jeepney drivers drastically, provoking many reactions. These changes have, of course, shifted the daily lives of the jeepney drivers significantly, but through adaptability, they found ways. Recommendations include flexible compliance policies, educational initiatives, and support for drivers, providing valuable insights for informed decision-making in the ongoing transportation modernization discussion. This study concluded that while the drivers are not opposed to reform, they are not entirely in approval of the current effects of the program as it is being implemented in their local area. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=transport%20reform" title="transport reform">transport reform</a>, <a href="https://publications.waset.org/abstracts/search?q=transport%20modernization" title=" transport modernization"> transport modernization</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20transport" title=" public transport"> public transport</a>, <a href="https://publications.waset.org/abstracts/search?q=jeepney%20drivers" title=" jeepney drivers"> jeepney drivers</a>, <a href="https://publications.waset.org/abstracts/search?q=PUVMP" title=" PUVMP"> PUVMP</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20planning" title=" urban planning"> urban planning</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20utility%20vehicles" title=" public utility vehicles"> public utility vehicles</a> </p> <a href="https://publications.waset.org/abstracts/182056/pull-string-to-stop-public-utility-vehicle-modernization-program" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182056.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">68</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> Physiological Roles of Relaxin on Prefertilizing Activities of Spermatozoa</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20G.%20Miah">A.

Previously it was considered as only the hormone of pregnant mammals due to its important roles in pregnancy and parturition. From the last decade, the physiological role of relaxin in male reproduction has been given experimental attention, and the results have made it clear that relaxin can no longer be considered strictly as only the hormone of female reproduction. The accessory glands (specially, the prostate glands) of the male reproductive system are the source of seminal relaxin, which is secreted into the seminal plasma and saturated with spermatozoa just after ejaculation. Several studies have reported that relaxin has important roles in improving motility in human sperm. Thereafter, the growing interest on relaxin has intensified efforts to investigate the role of relaxin in other sperm physiological phenomena like, capacitation, acrosome reaction, and their mediating factors associated with successful fertilization. Therefore, this review aims to provide up-to-date information about the physiological roles of relaxin in sperm motility, capacitation, acrosome reaction, and their mediating factors, such as, utilization of glucose, cholesterol efflux, Ca2+-influx, intracellular cAMP and protein tyrosine phosphorylation. Some studies have shown relaxin to increase the percentage of progressive motility and induce capacitation and acrosome reaction through increasing the utilization of glucose and mediating the cholesterol efflux, Ca2+-influx, intracellular cAMP and protein tyrosine phosphorylation. Thus, the review suggests that the supplementation of relaxin into the capacitating medium may contribute the possible beneficial roles in fresh and cryopreserved spermatozoal prefertilization events. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=relaxin" title="relaxin">relaxin</a>, <a href="https://publications.waset.org/abstracts/search?q=physiological%20roles" title=" physiological roles"> physiological roles</a>, <a href="https://publications.waset.org/abstracts/search?q=prefertilizing%20activities" title=" prefertilizing activities"> prefertilizing activities</a>, <a href="https://publications.waset.org/abstracts/search?q=spermatozoa" title=" spermatozoa"> spermatozoa</a> </p> <a href="https://publications.waset.org/abstracts/24124/physiological-roles-of-relaxin-on-prefertilizing-activities-of-spermatozoa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24124.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">568</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> Fully Automated Methods for the Detection and Segmentation of Mitochondria in Microscopy Images</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Blessing%20Ojeme">Blessing Ojeme</a>, <a href="https://publications.waset.org/abstracts/search?q=Frederick%20Quinn"> Frederick Quinn</a>, <a href="https://publications.waset.org/abstracts/search?q=Russell%20Karls"> Russell Karls</a>, <a href="https://publications.waset.org/abstracts/search?q=Shannon%20Quinn"> Shannon Quinn</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The detection and segmentation of mitochondria from fluorescence microscopy are crucial for understanding the complex structure of the nervous system. However, the constant fission and fusion of mitochondria and image distortion in the background make the task of detection and segmentation challenging. In the literature, a number of open-source software tools and artificial intelligence (AI) methods have been described for analyzing mitochondrial images, achieving remarkable classification and quantitation results. However, the availability of combined expertise in the medical field and AI required to utilize these tools poses a challenge to its full adoption and use in clinical settings. Motivated by the advantages of automated methods in terms of good performance, minimum detection time, ease of implementation, and cross-platform compatibility, this study proposes a fully automated framework for the detection and segmentation of mitochondria using both image shape information and descriptive statistics. Using the low-cost, open-source python and openCV library, the algorithms are implemented in three stages: pre-processing, image binarization, and coarse-to-fine segmentation. The proposed model is validated using the mitochondrial fluorescence dataset. Ground truth labels generated using a Lab kit were also used to evaluate the performance of our detection and segmentation model. The study produces good detection and segmentation results and reports the challenges encountered during the image analysis of mitochondrial morphology from the fluorescence mitochondrial dataset. A discussion on the methods and future perspectives of fully automated frameworks conclude the paper. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=2D" title="2D">2D</a>, <a href="https://publications.waset.org/abstracts/search?q=binarization" title=" binarization"> binarization</a>, <a href="https://publications.waset.org/abstracts/search?q=CLAHE" title=" CLAHE"> CLAHE</a>, <a href="https://publications.waset.org/abstracts/search?q=detection" title=" detection"> detection</a>, <a href="https://publications.waset.org/abstracts/search?q=fluorescence%20microscopy" title=" fluorescence microscopy"> fluorescence microscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=mitochondria" title=" mitochondria"> mitochondria</a>, <a href="https://publications.waset.org/abstracts/search?q=segmentation" title=" segmentation"> segmentation</a> </p> <a href="https://publications.waset.org/abstracts/153306/fully-automated-methods-for-the-detection-and-segmentation-of-mitochondria-in-microscopy-images" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153306.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">357</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> Exploring the Working Conditions of Physical Education Teachers in Times of COVID-19: A Phenomenological Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Raziel%20Mojica">Raziel Mojica</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study delves into the challenging working conditions faced by physical education (PE) teachers in public schools, particularly during the transition to remote teaching due to the impact of the COVID-19 pandemic. Using a qualitative, hermeneutic phenomenological approach, the research involves in-depth interviews with PE teachers to gain profound insight into their lived experiences and to answer the main question: What is the essence of the lived experience of physical education? The study explores the following sub-questions: (1) How do the participants describe their lived experience regarding their working conditions as physical education teachers in the new normal setup?; (2) What themes emerge from the testimonies of Physical Education Public School teachers from the Division of Calamba?; (3) Based on the consolidated findings and reflection, what material may be produced to inspire the physical education public school teachers? The study identifies emerging themes such as professional growth, personal life boundaries, accessible facilities and equipment, time management, and school leadership. Framed by Frederick Herzberg's Work-Motivation Theory, the study emphasizes motivator and hygienic factors that significantly impact job satisfaction and dissatisfaction. As a result of the study, the teachers vividly identified the challenges they face, including the lack of resources, training, and support from school leaders, which have made it difficult for them to adapt to the new teaching environment. These findings underscore the urgent need to revise teacher training curricula and for school leaders to provide strategic support to PE teachers in remote learning contexts. In conclusion, the study recommends targeted interventions to address these challenges and better equip PE teachers for the new normal in education. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=PE%20teachers" title="PE teachers">PE teachers</a>, <a href="https://publications.waset.org/abstracts/search?q=COVID-19%20pandemic" title=" COVID-19 pandemic"> COVID-19 pandemic</a>, <a href="https://publications.waset.org/abstracts/search?q=hermeneutic%20phenomenological" title=" hermeneutic phenomenological"> hermeneutic phenomenological</a>, <a href="https://publications.waset.org/abstracts/search?q=physical%20education" title=" physical education"> physical education</a>, <a href="https://publications.waset.org/abstracts/search?q=new%20normal" title=" new normal"> new normal</a> </p> <a href="https://publications.waset.org/abstracts/192251/exploring-the-working-conditions-of-physical-education-teachers-in-times-of-covid-19-a-phenomenological-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/192251.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">27</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">14</span> Probability Sampling in Matched Case-Control Study in Drug Abuse</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Surya%20R.%20Niraula">Surya R.

Connell</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Although random sampling is generally considered to be the gold standard for population-based research, the majority of drug abuse research is based on non-random sampling despite the well-known limitations of this kind of sampling. Method: We compared the statistical properties of two surveys of drug abuse in the same community: one using snowball sampling of drug users who then identified “friend controls” and the other using a random sample of non-drug users (controls) who then identified “friend cases.” Models to predict drug abuse based on risk factors were developed for each data set using conditional logistic regression. We compared the precision of each model using bootstrapping method and the predictive properties of each model using receiver operating characteristics (ROC) curves. Results: Analysis of 100 random bootstrap samples drawn from the snowball-sample data set showed a wide variation in the standard errors of the beta coefficients of the predictive model, none of which achieved statistical significance. One the other hand, bootstrap analysis of the random-sample data set showed less variation, and did not change the significance of the predictors at the 5% level when compared to the non-bootstrap analysis. Comparison of the area under the ROC curves using the model derived from the random-sample data set was similar when fitted to either data set (0.93, for random-sample data vs. 0.91 for snowball-sample data, p=0.35); however, when the model derived from the snowball-sample data set was fitted to each of the data sets, the areas under the curve were significantly different (0.98 vs. 0.83, p < .001). Conclusion: The proposed method of random sampling of controls appears to be superior from a statistical perspective to snowball sampling and may represent a viable alternative to snowball sampling. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=drug%20abuse" title="drug abuse">drug abuse</a>, <a href="https://publications.waset.org/abstracts/search?q=matched%20case-control%20study" title=" matched case-control study"> matched case-control study</a>, <a href="https://publications.waset.org/abstracts/search?q=non-probability%20sampling" title=" non-probability sampling"> non-probability sampling</a>, <a href="https://publications.waset.org/abstracts/search?q=probability%20sampling" title=" probability sampling"> probability sampling</a> </p> <a href="https://publications.waset.org/abstracts/24612/probability-sampling-in-matched-case-control-study-in-drug-abuse" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24612.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">493</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> Crystalline Silica Exposure in Tunnelling: Identifying Barriers to Safe Practices</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Frederick%20Anlimah">Frederick Anlimah</a>, <a href="https://publications.waset.org/abstracts/search?q=Vinod%20Gopaldasani"> Vinod Gopaldasani</a>, <a href="https://publications.waset.org/abstracts/search?q=Catherine%20MacPhail"> Catherine MacPhail</a>, <a href="https://publications.waset.org/abstracts/search?q=Brian%20Davies"> Brian Davies</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The construction industry, particularly tunnel construction, exposes workers to respirable crystalline silica (RCS), which can cause incurable illnesses such as silicosis and lung cancer. Despite various control measures, exposures remain inadequately controlled. This research aimed to identify the barriers and challenges hindering the implementation of effective controls and the adoption of safe work practices to protect workers from RCS exposure in tunnelling. A mixed-method approach was employed for this research. Tunnel construction workers were observed, surveyed and interviewed to gauge their knowledge and attitudes and understand their challenges in reducing RCS exposure. The preliminary analysis of the data reveals a diverse array of sociotechnical factors interacting to influence RCS exposure. It is noteworthy that participants consistently emphasised the project as the most exemplary one they have been involved in, although there is room for improvement. While there is a commendable level of knowledge about RCS exposure and control in tunnelling, there is a striking lack of perceived satisfaction regarding dust control. Several factors were identified as interacting to prevent the effective management of dust. These include perceived time pressure, absence of on-tool dust controls, low risk perceptions among workers, and inadequate enforcement of controls. Moreover, participants highlighted communication and heat-related challenges as hindrances to the continuous wear of respirators. This research highlights the need for a paradigm shift in tunnel construction to address the barriers associated with RCS exposure reduction. It emphasises the importance of collaboration among various stakeholders, advocating for more effective controls and enforcement strategies and enhanced worker education through knowledge sharing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=respirable%20crystalline%20silica" title="respirable crystalline silica">respirable crystalline silica</a>, <a href="https://publications.waset.org/abstracts/search?q=dust%20control" title=" dust control"> dust control</a>, <a href="https://publications.waset.org/abstracts/search?q=worker%20practices" title=" worker practices"> worker practices</a>, <a href="https://publications.waset.org/abstracts/search?q=exposure%20prevention" title=" exposure prevention"> exposure prevention</a>, <a href="https://publications.waset.org/abstracts/search?q=silicosis" title=" silicosis"> silicosis</a> </p> <a href="https://publications.waset.org/abstracts/177376/crystalline-silica-exposure-in-tunnelling-identifying-barriers-to-safe-practices" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/177376.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">68</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> Synthesis of Double Dye-Doped Silica Nanoparticles and Its Application in Paper-Based Chromatography</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ka%20Ho%20Yau">Ka Ho Yau</a>, <a href="https://publications.waset.org/abstracts/search?q=Jan%20Frederick%20Engels"> Jan Frederick Engels</a>, <a href="https://publications.waset.org/abstracts/search?q=Kwok%20Kei%20Lai"> Kwok Kei Lai</a>, <a href="https://publications.waset.org/abstracts/search?q=Reinhard%20Renneberg"> Reinhard Renneberg</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Lateral flow test is a prevalent technology in various sectors such as food, pharmacology and biomedical sciences. Colloidal gold (CG) is widely used as the signalling molecule because of the ease of synthesis, bimolecular conjugation and its red colour due to intrinsic SPRE. However, the production of colloidal gold is costly and requires vigorous conditions. The stability of colloidal gold are easily affected by environmental factors such as pH, high salt content etc. Silica nanoparticles are well known for its ease of production and stability over a wide range of solvents. Using reverse micro-emulsion (w/o), silica nanoparticles with different sizes can be produced precisely by controlling the amount of water. By incorporating different water-soluble dyes, a rainbow colour of the silica nanoparticles could be produced. Conjugation with biomolecules such as antibodies can be achieved after surface modification of the silica nanoparticles with organosilane. The optimum amount of the antibodies to be labelled was determined by Bradford Assay. In this work, we have demonstrated the ability of the dye-doped silica nanoparticles as a signalling molecule in lateral flow test, which showed a semi-quantitative measurement of the analyte. The image was further analysed for the LOD=10 ng of the analyte. The working range and the linear range of the test were from 0 to 2.15μg/mL and from 0 to 1.07 μg/mL (R2=0.988) respectively. The performance of the tests was comparable to those using colloidal gold with the advantages of lower cost, enhanced stability and having a wide spectrum of colours. The positives lines can be imaged by naked eye or by using a mobile phone camera for a better quantification. Further research has been carried out in multicolour detection of different biomarkers simultaneously. The preliminary results were promising as there was little cross-reactivity being observed for an optimized system. This approach provides a platform for multicolour detection for a set of biomarkers that enhances the accuracy of diseases diagnostics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=colorimetric%20detection" title="colorimetric detection">colorimetric detection</a>, <a href="https://publications.waset.org/abstracts/search?q=immunosensor" title=" immunosensor"> immunosensor</a>, <a href="https://publications.waset.org/abstracts/search?q=paper-based%20biosensor" title=" paper-based biosensor"> paper-based biosensor</a>, <a href="https://publications.waset.org/abstracts/search?q=silica" title=" silica"> silica</a> </p> <a href="https://publications.waset.org/abstracts/42176/synthesis-of-double-dye-doped-silica-nanoparticles-and-its-application-in-paper-based-chromatography" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42176.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">385</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> Crystalline Silica Exposure in Tunnel Construction: Identifying Barriers to Safe Practices</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Frederick%20Anlimah">Frederick Anlimah</a>, <a href="https://publications.waset.org/abstracts/search?q=Vinod%20Gopaldasani"> Vinod Gopaldasani</a>, <a href="https://publications.waset.org/abstracts/search?q=Catherine%20MacPhail"> Catherine MacPhail</a>, <a href="https://publications.waset.org/abstracts/search?q=Brian%20Davies"> Brian Davies</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aim: This study aims to identify the barriers and challenges hindering the implementation of effective controls and the adoption of safe work practices to protect workers from respirable crystalline silica (RCS) exposure. Problem or Situation: Tunnelling is one of many occupations that expose workers to the harmful effects of respirable crystalline silica. Despite various control measures, such as engineering controls and personal protective equipment, exposures remain inadequately controlled, leading to incurable silicosis and other severe illnesses, such as lung cancer. Methods: The research involved surveying tunnel construction workers, conducting interviews, and facilitating focus group discussions. Additionally, site observations and content analysis of work procedures and instructions were performed. Results: Preliminary data analysis reveals notable findings. While there is a commendable level of knowledge and commitment among management and workers concerning RCS exposure in tunnelling, there is a striking lack of prioritization regarding dust control. Moreover, the risks associated with dust exposure are not sufficiently acknowledged. Additionally, the data suggests that engineers and supervisors responsible for implementing dust controls often possess limited knowledge regarding the factors influencing the effectiveness of these measures. These findings emphasise the need for a paradigm shift, including higher prioritisation of dust control, adoption of holistic dust reduction strategies, and enhanced knowledge about effective control measures. Conclusion: This research shed light on tunnel construction workers' barriers and challenges in protecting themselves from RCS exposure. This knowledge will be essential in developing interventions and strategies to enhance dust exposure and prevent the adverse health effects of respirable crystalline silica exposure in tunnelling and similar industries. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=respirable%20crystalline%20silica" title="respirable crystalline silica">respirable crystalline silica</a>, <a href="https://publications.waset.org/abstracts/search?q=dust%20control" title=" dust control"> dust control</a>, <a href="https://publications.waset.org/abstracts/search?q=worker%20practices" title=" worker practices"> worker practices</a>, <a href="https://publications.waset.org/abstracts/search?q=exposure%20prevention" title=" exposure prevention"> exposure prevention</a>, <a href="https://publications.waset.org/abstracts/search?q=silicosis" title=" silicosis"> silicosis</a> </p> <a href="https://publications.waset.org/abstracts/173532/crystalline-silica-exposure-in-tunnel-construction-identifying-barriers-to-safe-practices" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/173532.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">71</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">10</span> Bridging Cultures in Distance Education: A Confluence of Critical Pedagogy of Place and Indigenous Education Philosophy (Case-Study Reference in Fiji and Vanuatu)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dan%20Frederick%20Orcherton">Dan Frederick Orcherton</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research explores the fusion of "Critical Pedagogy of Place" and "Indigenous Education Philosophy" to create a holistic pedagogical framework within Instructional Theory, focusing on its application in Distance Education, specifically within two Pacific Island cultures. The study's objectives included investigating culturally relevant instructional techniques, strategies, and technologies for the Itaukei (Indigenous Fijian) and ni-Vanuatu cultures, enhancing appreciation for culturally sensitive pedagogical methods. Methodologically, a qualitative inquiry phenomenological approach was employed within a constructivist paradigm, utilizing a comprehensive qualitative scoping review and online literature search. Key findings include the prioritization of cultural inclusivity and indigenous knowledge integration in both indigenous education philosophies and various instructional approaches. Learner-centered methods like constructivist andragogy and the learning cycle are applicable and effective in distance education within these cultures, aligning with indigenous learners' values and preferences. Place-based education and critical pedagogy of place are particularly pertinent, fostering a deeper connection between education, local environments, and social justice. Integrating digital technologies in culturally responsive education bridges geographical gaps and preserves cultural knowledge. Lastly, blending Western and Indigenous Science, influenced by a Two-Eyed Seeing approach, informs pedagogy by combining Western and Indigenous Science. This research underscores the importance of acknowledging cultural diversity and respecting indigenous knowledge in distance education. It highlights the value of learner-centered approaches, place-based education, and technology integration. The study enriches the educational experience within the Itaukei and niVanuatu cultures and provides insights for educators and policymakers aiming to bridge cultural gaps in distance education. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=critical%20pedegory%20of%20place" title="critical pedegory of place">critical pedegory of place</a>, <a href="https://publications.waset.org/abstracts/search?q=Itaukei%20%28indigenous%20Fijian%29%20and%20ni-Vanuatu%20cultures" title=" Itaukei (indigenous Fijian) and ni-Vanuatu cultures"> Itaukei (indigenous Fijian) and ni-Vanuatu cultures</a>, <a href="https://publications.waset.org/abstracts/search?q=placed-based%20education" title=" placed-based education"> placed-based education</a>, <a href="https://publications.waset.org/abstracts/search?q=indigenous%20knowledge" title=" indigenous knowledge"> indigenous knowledge</a>, <a href="https://publications.waset.org/abstracts/search?q=distance%20education" title=" distance education"> distance education</a> </p> <a href="https://publications.waset.org/abstracts/189434/bridging-cultures-in-distance-education-a-confluence-of-critical-pedagogy-of-place-and-indigenous-education-philosophy-case-study-reference-in-fiji-and-vanuatu" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/189434.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">19</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9</span> An Investigative Study into Good Governance in the Non-Profit Sector in South Africa: A Systems Approach Perspective</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Frederick%20M.%20Dumisani%20Xaba">Frederick M.

Khanyile</a> </p> <p class="card-text"><strong>Abstract:</strong></p> There is a growing demand for greater accountability, transparency and ethical conduct based on sound governance principles in the developing world. Funders, donors and sponsors are increasingly demanding more transparency, better value for money and adherence to good governance standards. The drive towards improved governance measures is largely influenced by the need to ‘plug the leaks’, deal with malfeasance, engender greater levels of accountability and good governance and to ultimately attract further funding or investment. This is the case with the Non-Profit Organizations (NPOs) in South Africa in general, and in the province of KwaZulu-Natal in particular. The paper draws from the good governance theory, stakeholder theory and systems thinking to critically examine the requirements for good governance for the NPO sector from a theoretical and legislative point and to systematically looks at the contours of governance currently among the NPOs. The paper did this through the rigorous examination of the vignettes of cases of governance among selected NPOs based in KwaZulu-Natal. The study used qualitative and quantitative research methodologies through document analysis, literature review, semi-structured interviews, focus groups and statistical analysis from the various primary and secondary sources. It found some good cases of good governance but also found frightening levels of poor governance. There was an exponential growth of NPOs registered during the period under review, equally so there was an increase in cases of non-compliance to good governance practices. NPOs operate in an increasingly complex environment. There is contestation for influence and access to resources. Stakeholder management is poorly conceptualized and executed. Recognizing that the NPO sector operates in an environment characterized by complexity, constant changes, unpredictability, contestation, diversity and divergent views of different stakeholders, there is a need to apply legislative and systems thinking approaches to strengthen governance to withstand this turbulence through a capacity development model that recognizes these contextual and environmental challenges. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=good%20governance" title="good governance">good governance</a>, <a
