Vizenor's work critiques the notion of irrevocable cultural loss and rigid definitions of Indigenous identity based on blood quantum and stereotypical practices. Through subversive humor, trickster figures, and storytelling, Vizenor asserts the active presence and continuance of Native peoples, advocating for a dynamic, self-determined understanding of Native identity. The essay examines Vizenor's use of postmodern techniques, including his engagement with simulation and hyperreality, to disrupt colonial discourses and create new spaces for Indigenous expression. It explores the concept of "crossblood" identities as a means of resisting essentialist notions of Native authenticity and embracing the complexities of contemporary Indigenous experiences. Vizenor's ideas of survivance and transmotion are analyzed as strategies for cultural resilience and adaptation in the face of ongoing colonial pressures. The interplay between absence and presence in Vizenor's work is discussed, particularly through the lens of shadow survivance and the power of storytelling. The essay also delves into Vizenor's critique of terminal creed and his promotion of natural reason as an alternative epistemology to Western rationalism. While acknowledging the significant influence of Vizenor's work on Native American literature and theory, the essay also addresses critiques of his approach, including concerns about the accessibility of his writing and its political effectiveness. Despite these debates, the essay argues that Vizenor's concepts offer a powerful vision of Indigenous futurity that is rooted in tradition yet open to change, inspiring hope and agency in the face of oppression. By examining Vizenor's multifaceted approach to Native American identity and presence, this essay contributes to ongoing discussions about Indigenous representation, cultural continuity, and resistance to colonial narratives in literature and beyond. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gerald%20vizenor" title="gerald vizenor">gerald vizenor</a>, <a href="https://publications.waset.org/abstracts/search?q=identity%20native%20american%20literature" title=" identity native american literature"> identity native american literature</a>, <a href="https://publications.waset.org/abstracts/search?q=survivance" title=" survivance"> survivance</a>, <a href="https://publications.waset.org/abstracts/search?q=trickster%20discourse" title=" trickster discourse"> trickster discourse</a>, <a href="https://publications.waset.org/abstracts/search?q=identity" title=" identity"> identity</a> </p> <a href="https://publications.waset.org/abstracts/189261/beyond-the-tragedy-of-absence-vizenors-comedy-of-native-presence" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/189261.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">34</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">40</span> Low-Emission Commuting with Micro Public Transport: Investigation of Travel Times and CO₂ Emissions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marcel%20Ciesla">Marcel Ciesla</a>, <a href="https://publications.waset.org/abstracts/search?q=Victoria%20Oberascher"> Victoria Oberascher</a>, <a href="https://publications.waset.org/abstracts/search?q=Sven%20Eder"> Sven Eder</a>, <a href="https://publications.waset.org/abstracts/search?q=Stefan%20Kirchweger"> Stefan Kirchweger</a>, <a href="https://publications.waset.org/abstracts/search?q=Wolfgang%20E.%20Baaske"> Wolfgang E.

Assuming high market volatility as an impetus to seek a safe haven in gold, the return of gold relative to the stock market, as measured by the S&P 500, is tracked. Using the Chicago Board Options Exchange (CBOE) volatility index (VIX) as a measure of stock market volatility, various criteria are established for when an investor would seek a safe haven to avoid high levels of risk. The results show that in a vast majority of cases, the S&P 500 outperforms gold during these periods of high volatility and suggests investors who seek safe haven are underperforming the market. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gold" title="gold">gold</a>, <a href="https://publications.waset.org/abstracts/search?q=portfolio%20management" title=" portfolio management"> portfolio management</a>, <a href="https://publications.waset.org/abstracts/search?q=safe%20haven" title=" safe haven"> safe haven</a>, <a href="https://publications.waset.org/abstracts/search?q=VIX" title=" VIX"> VIX</a> </p> <a href="https://publications.waset.org/abstracts/137176/seeking-safe-haven-an-analysis-of-gold-performance-during-periods-of-high-volatility" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137176.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">163</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> Towards Automated Remanufacturing of Marine and Offshore Engineering Components </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aprilia">Aprilia</a>, <a href="https://publications.waset.org/abstracts/search?q=Wei%20Liang%20Keith%20Nguyen"> Wei Liang Keith Nguyen</a>, <a href="https://publications.waset.org/abstracts/search?q=Shu%20Beng%20Tor"> Shu Beng Tor</a>, <a href="https://publications.waset.org/abstracts/search?q=Gerald%20Gim%20Lee%20Seet"> Gerald Gim Lee Seet</a>, <a href="https://publications.waset.org/abstracts/search?q=Chee%20Kai%20Chua"> Chee Kai Chua</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Automated remanufacturing process is of great interest in today’s marine and offshore industry. Most of the current remanufacturing processes are carried out manually and hence they are error prone, labour-intensive and costly. In this paper, a conceptual framework for automated remanufacturing is presented. This framework involves the integration of 3D non-contact digitization, adaptive surface reconstruction, additive manufacturing and machining operation. Each operation is operated and interconnected automatically as one system. The feasibility of adaptive surface reconstruction on marine and offshore engineering components is also discussed. Several engineering components were evaluated and the results showed that this proposed system is feasible.

Zits travels in time and views the world from different bodies, ages, and races; his journeys end with different perspectives on the idea of nationhood as an American Indian. He is an example of Vine Deloria’s statementthat “urban Indians have become the cutting edge of the new Indian nationalism” (248). Flight is chosen because the momentZits leaves the real world for time-traveling adventures is very critical; it is a moment of rage that ends in the mass murder of many Anglo-Americans. The paper focus on the turning point when he returns into his body with new opportunities towards his existence among the majority of anglo-Americans who cannot help but see him American Indian minority in need of help and assistance. Characters, such as Zits, attempt to outlive alienation, and Alexie gives new definitionsof their ethnic nationhood. Futuristicdoes not mean the very far unpredictable future; it is rather a nearpotential future for teenagers of American Indians, like Zits, Arnold, andCoyoteSprings- the band in ReservationBlues; all revolutionary personalitiesin Alexie’s works. They will be analyzed as Gerald Vizenor’s “postindianwarriors” who have the ability to identify Indigenous nationalism in a post-colonial context. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alienation" title="alienation">alienation</a>, <a href="https://publications.waset.org/abstracts/search?q=self-identification" title="self-identification">self-identification</a>, <a href="https://publications.waset.org/abstracts/search?q=nationhood" title=" nationhood"> nationhood</a>, <a href="https://publications.waset.org/abstracts/search?q=urbanization" title=" urbanization"> urbanization</a>, <a href="https://publications.waset.org/abstracts/search?q=postindian" title=" postindian"> postindian</a> </p> <a href="https://publications.waset.org/abstracts/144010/a-futuristic-look-at-american-indian-nationhood-zits-in-sherman-alexies-flight" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144010.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">35</span> Fiber-Based 3D Cellular Reinforcing Structures for Mineral-Bonded Composites with Enhanced Structural Impact Tolerance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Duy%20M.%20P.%20Vo">Duy M.

The research training group GRK 2250/1 aims to develop mineral-bonded composites that allow the fabrication of thin-layered strengthening layers providing available concrete members with enhanced impact resistance. This paper presents the development of 3D woven wire cellular structures that can be used as innovative reinforcement for targeted composites. 3D woven wire cellular structures are truss-like architectures that can be fabricated in an automatized process with a great customization possibility. The specific architecture allows this kind of structures to have good load bearing capability and forming behavior, which is of great potential to give strength against impact loading. An appropriate combination of topology and material enables an optimal use of thin-layered reinforcement in concrete constructions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=3D%20woven%20cellular%20structures" title="3D woven cellular structures">3D woven cellular structures</a>, <a href="https://publications.waset.org/abstracts/search?q=ductile%20behavior" title=" ductile behavior"> ductile behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20absorption" title=" energy absorption"> energy absorption</a>, <a href="https://publications.waset.org/abstracts/search?q=fiber-based%20reinforced%20concrete" title=" fiber-based reinforced concrete"> fiber-based reinforced concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=impact%20resistant" title=" impact resistant"> impact resistant</a> </p> <a href="https://publications.waset.org/abstracts/92338/fiber-based-3d-cellular-reinforcing-structures-for-mineral-bonded-composites-with-enhanced-structural-impact-tolerance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92338.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">298</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> Local Community Participation and the Adoption of Agricultural Technology in Kayunga District, Uganda</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Barbara%20Kyampeire">Barbara Kyampeire</a>, <a href="https://publications.waset.org/abstracts/search?q=Gerald%20Karyeijja"> Gerald Karyeijja</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study investigated the influence of local community participation on the adoption of new agricultural technology in Uganda, using the case study of Smooth Cayenne Pineapples in Kayunga District, Uganda. The mechanism of adoption of new technologies is often not fully understood and this prompted the study. The study adopted a descriptive, co relational, survey design. The researcher used questionnaire survey, focus group discussion as methods of data collection. A total of 152 respondents including adopters and non-adopters of new technology for producing pineapples were selected from 8 farmer groups in Kayunga District. The results indicated that the participation of the community in the planning, implementation and the monitoring and evaluation of the adoption of the new technology for producing pineapples was low thus reducing the adoption of the new technology in the District. The researcher concluded that community participation significantly influences the adoption of new agricultural technology by members of a particular community. The study thus recommended that: first, there is need for maximum involvement of members of the community in the planning, implementation and monitoring of any new agricultural technology; secondly, there is need for continued sharing of information about new agricultural technologies being introduced; and finally, community members must be equipped with Monitoring and Evaluation (M&E) skills in order to make them monitor the progress made by the new agricultural technologies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adoption" title="adoption">adoption</a>, <a href="https://publications.waset.org/abstracts/search?q=community" title=" community"> community</a>, <a href="https://publications.waset.org/abstracts/search?q=technology" title=" technology"> technology</a>, <a href="https://publications.waset.org/abstracts/search?q=implementation" title=" implementation "> implementation </a> </p> <a href="https://publications.waset.org/abstracts/35785/local-community-participation-and-the-adoption-of-agricultural-technology-in-kayunga-district-uganda" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35785.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">426</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> Analysis of the Extreme Hydrometeorological Events in the Theorical Hydraulic Potential and Streamflow Forecast</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sara%20Patricia%20Ibarra-Zavaleta">Sara Patricia Ibarra-Zavaleta</a>, <a href="https://publications.waset.org/abstracts/search?q=Rabindranarth%20Romero-Lopez"> Rabindranarth Romero-Lopez</a>, <a href="https://publications.waset.org/abstracts/search?q=Rosario%20Langrave"> Rosario Langrave</a>, <a href="https://publications.waset.org/abstracts/search?q=Annie%20Poulin"> Annie Poulin</a>, <a href="https://publications.waset.org/abstracts/search?q=Gerald%20Corzo"> Gerald Corzo</a>, <a href="https://publications.waset.org/abstracts/search?q=Mathias%20Glaus"> Mathias Glaus</a>, <a href="https://publications.waset.org/abstracts/search?q=Ricardo%20Vega-Azamar"> Ricardo Vega-Azamar</a>, <a href="https://publications.waset.org/abstracts/search?q=Norma%20Angelica%20Oropeza"> Norma Angelica Oropeza</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The progressive change in climatic conditions worldwide has increased frequency and severity of extreme hydrometeorological events (EHE). Mexico is an example; this has been affected by the presence of EHE leaving economic, social and environmental losses. The objective of this research was to apply a Canadian distributed hydrological model (DHM) to tropical conditions and to evaluate its capacity to predict flows in a basin in the central Gulf of Mexico. In addition, the DHM (once calibrated and validated) was used to calculate the theoretical hydraulic power and the performance to predict streamflow before the presence of an EHE. The results of the DHM show that the goodness of fit indicators between the observed and simulated flows in the calibration process (NSE=0.83, RSR=0.021 and BIAS=-4.3) and validation: temporal was assessed at two points: point one (NSE=0.78, RSR=0.113 and BIAS=0.054) and point two (NSE=0.825, RSR=0.103 and BIAS=0.063) are satisfactory. The DHM showed its applicability in tropical environments and its ability to characterize the rainfall-runoff relationship in the study area. This work can serve as a tool for identifying vulnerabilities before floods and for the rational and sustainable management of water resources. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=HYDROTEL" title="HYDROTEL">HYDROTEL</a>, <a href="https://publications.waset.org/abstracts/search?q=hydraulic%20power" title=" hydraulic power"> hydraulic power</a>, <a href="https://publications.waset.org/abstracts/search?q=extreme%20hydrometeorological%20events" title=" extreme hydrometeorological events"> extreme hydrometeorological events</a>, <a href="https://publications.waset.org/abstracts/search?q=streamflow" title=" streamflow"> streamflow</a> </p> <a href="https://publications.waset.org/abstracts/85335/analysis-of-the-extreme-hydrometeorological-events-in-the-theorical-hydraulic-potential-and-streamflow-forecast" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85335.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">341</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> Listening to the Voices of Syrian Refugee Women in Canada: An Ethnographic Insight into the Journey from Trauma to Adaptation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Areej%20Al-Hamad">Areej Al-Hamad</a>, <a href="https://publications.waset.org/abstracts/search?q=Cheryl%20Forchuk"> Cheryl Forchuk</a>, <a href="https://publications.waset.org/abstracts/search?q=Abe%20Oudshoorn"> Abe Oudshoorn</a>, <a href="https://publications.waset.org/abstracts/search?q=Gerald%20Patrick%20Mckinley"> Gerald Patrick Mckinley</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Syrian refugee women face many obstacles when accessing health services in host countries that are influenced by various cultural, structural, and practical factors. This paper is based on critical ethnographic research undertaken in Canada to explore Syrian refugee women's migration experiences. Also, we aim to critically examine how the intersection of gender, trauma, violence and the political and economic conditions of Syrian refugee women shapes their everyday lives and health. The study also investigates the strategies and practices by which Syrian refugee women are currently addressing their healthcare needs and the models of care that are suggested for meeting their physical and mental health needs. Findings show that these women experienced constant worries, hardship, vulnerability, and intrusion of dignity. These experiences and challenges were aggravated by the structure of the Canadian social and health care system. This study offers a better understanding of the impact of migration and trauma on Syrian refugee women's roles, responsibilities, gender dynamics, and interaction with Ontario's healthcare system to improve interaction and outcomes. Health care models should address these challenges among Syrian refugee families in Canada. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Syrian%20refugee%20women" title="Syrian refugee women">Syrian refugee women</a>, <a href="https://publications.waset.org/abstracts/search?q=intersectionality" title=" intersectionality"> intersectionality</a>, <a href="https://publications.waset.org/abstracts/search?q=critical%20ethnography" title=" critical ethnography"> critical ethnography</a>, <a href="https://publications.waset.org/abstracts/search?q=migration" title=" migration"> migration</a> </p> <a href="https://publications.waset.org/abstracts/155302/listening-to-the-voices-of-syrian-refugee-women-in-canada-an-ethnographic-insight-into-the-journey-from-trauma-to-adaptation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155302.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">95</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> Project Financing and Poverty Trends in the Islamic Development Bank Member Countries</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sennanda%20Musa">Sennanda Musa</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Mutunzi%20Kitunzi"> Ahmed Mutunzi Kitunzi</a>, <a href="https://publications.waset.org/abstracts/search?q=Gerald%20Kasigwa"> Gerald Kasigwa</a>, <a href="https://publications.waset.org/abstracts/search?q=Ismail%20Kintu"> Ismail Kintu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper is an analysis of the empirical relationship between project financing by Islamic Development Bank (IsDB) and the poverty trends in the context of countries benefiting from IsDB. Specifically, the study seeks to find out whether there is a statistically significant relationship between the project financing dollar amounts by IsDB (PF) and the GNI Per Capita, PPP of 57 countries for the years 2002 to 2021. The research is a longitudinal, desk-top triangulation of correlation, regression, hypothesis-testing employing the linear dynamic panel data GMM model as an estimator of the empirical relationships between the key variables of the study. The study results show that there is a significant positive relationship between the PF dollar amounts from the IsDB and the GNI Per Capita, PPP in these 57 countries. Therefore, countries that receive higher PF dollar amounts from the IsDB, generally have more GNI Per Capita, PPP (less poverty) than their counterparts. It is, therefore, recommendable for countries to formulate policies that facilitate Islamically financed projects to mitigate poverty. This paper develops policy discussions regarding allocation of political attention to the policy topics on poverty mitigation, and their relation to financing projects Islamically, thus generate information on policy choices regarding the Islamic financing alternative. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gross-national-income" title="gross-national-income">gross-national-income</a>, <a href="https://publications.waset.org/abstracts/search?q=IsDB-project-financing" title=" IsDB-project-financing"> IsDB-project-financing</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20policy" title=" public policy"> public policy</a>, <a href="https://publications.waset.org/abstracts/search?q=poverty" title=" poverty"> poverty</a> </p> <a href="https://publications.waset.org/abstracts/164660/project-financing-and-poverty-trends-in-the-islamic-development-bank-member-countries" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164660.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">89</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> Characterization of Fresh, Charcoal Flue Gas Treated and Boiled Beef Samples Using FTIR For Consumption Safety</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Catherine%20W.%20Njeru">Catherine W.

This study used charcoal flue gases sourced from the combustion of charcoal briquettes to prolong beef shelf life. The FT-IR technique is based on the specific absorption of infrared radiation by carbon monoxide and carbon dioxide molecules. The characterization of the functional groups was done using Fourier transform infrared spectroscopy (Shimadzu IR Tracer-100). The fresh, treated and boiled beef was ground with potassium bromide (KBr) into pellets and analyzed using FT-IR at a range of 400-3600 cm-1. The reaction of fresh, charcoal flue gas treated and boiled beef samples are as shown in the FT-IR spectrums. The fresh and boiled beef spectrums are similar, while the charcoal flue-treated beef samples show distinct peaks at 2100 and 2290 cm-1, which correspond to carbon monoxide and carbon dioxide, respectively. The study proposes the use of FT-IR in the determination of beef for consumption quality studies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=FT-IR" title="FT-IR">FT-IR</a>, <a href="https://publications.waset.org/abstracts/search?q=charcoal%20flue%20gases" title=" charcoal flue gases"> charcoal flue gases</a>, <a href="https://publications.waset.org/abstracts/search?q=beef" title=" beef"> beef</a>, <a href="https://publications.waset.org/abstracts/search?q=charcoal%20flue%20gases" title=" charcoal flue gases"> charcoal flue gases</a> </p> <a href="https://publications.waset.org/abstracts/192426/characterization-of-fresh-charcoal-flue-gas-treated-and-boiled-beef-samples-using-ftir-for-consumption-safety" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/192426.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">24</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> SPBAC: A Semantic Policy-Based Access Control for Database Query</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aaron%20Zhang">Aaron Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Alimire%20Kahaer"> Alimire Kahaer</a>, <a href="https://publications.waset.org/abstracts/search?q=Gerald%20Weber"> Gerald Weber</a>, <a href="https://publications.waset.org/abstracts/search?q=Nalin%20Arachchilage"> Nalin Arachchilage</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Access control is an essential safeguard for the security of enterprise data, which controls users’ access to information resources and ensures the confidentiality and integrity of information resources [1]. Research shows that the more common types of access control now have shortcomings [2]. In this direction, to improve the existing access control, we have studied the current technologies in the field of data security, deeply investigated the previous data access control policies and their problems, identified the existing deficiencies, and proposed a new extension structure of SPBAC. SPBAC extension proposed in this paper aims to combine Policy-Based Access Control (PBAC) with semantics to provide logically connected, real-time data access functionality by establishing associations between enterprise data through semantics. Our design combines policies with linked data through semantics to create a "Semantic link" so that access control is no longer per-database and determines that users in each role should be granted access based on the instance policy, and improves the SPBAC implementation by constructing policies and defined attributes through the XACML specification, which is designed to extend on the original XACML model. While providing relevant design solutions, this paper hopes to continue to study the feasibility and subsequent implementation of related work at a later stage. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=access%20control" title="access control">access control</a>, <a href="https://publications.waset.org/abstracts/search?q=semantic%20policy-based%20access%20control" title=" semantic policy-based access control"> semantic policy-based access control</a>, <a href="https://publications.waset.org/abstracts/search?q=semantic%20link" title=" semantic link"> semantic link</a>, <a href="https://publications.waset.org/abstracts/search?q=access%20control%20model" title=" access control model"> access control model</a>, <a href="https://publications.waset.org/abstracts/search?q=instance%20policy" title=" instance policy"> instance policy</a>, <a href="https://publications.waset.org/abstracts/search?q=XACML" title=" XACML"> XACML</a> </p> <a href="https://publications.waset.org/abstracts/168587/spbac-a-semantic-policy-based-access-control-for-database-query" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168587.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">92</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> Determining the Prevalence and Risk Factors of Postpartum Depression</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gerald%20H.%20Artisen">Gerald H.

This research utilized a cross-sectional descriptive study to assess postpartum depression prevalence and identify contributing factors in Pasil, utilizing a quantitative approach and collecting data on sociodemographic characteristics, obstetric data, and the Edinburgh Postnatal Depression Scale. The study concluded that probable depression can be seen among mothers in the Pasil, which resulted in a risk of suicidality with a percentage of 40.08. Additionally, most of the respondents are aged 28–32, married, have a college degree, are unemployed, have a monthly income of 1,000–5,000, are female, have hypertension, gave birth naturally, have two children, have a planned pregnancy, and are currently breastfeeding. Lastly, the study found that mothers in Pasil who have unplanned pregnancies under obstetric factors are at high risk of developing postpartum depression, with a p-value below the 0.05 level. The study recommends barangay health professionals develop initiatives to inform aspiring mothers about postpartum depression (PPD) and resources to help them adjust to motherhood. It also recommends frequent check-ins with new mothers to identify special healthcare needs. Programs should be independently funded by LGUs, and support from family and relatives is recommended to prevent PPD. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=maternal%20health" title="maternal health">maternal health</a>, <a href="https://publications.waset.org/abstracts/search?q=postpartum%20depression" title=" postpartum depression"> postpartum depression</a>, <a href="https://publications.waset.org/abstracts/search?q=mothers" title=" mothers"> mothers</a>, <a href="https://publications.waset.org/abstracts/search?q=Pasil" title=" Pasil"> Pasil</a> </p> <a href="https://publications.waset.org/abstracts/191524/determining-the-prevalence-and-risk-factors-of-postpartum-depression" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/191524.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">29</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> Data Analytics in Energy Management</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sanjivrao%20Katakam">Sanjivrao Katakam</a>, <a href="https://publications.waset.org/abstracts/search?q=Thanumoorthi%20I."> Thanumoorthi I.</a>, <a href="https://publications.waset.org/abstracts/search?q=Antony%20Gerald"> Antony Gerald</a>, <a href="https://publications.waset.org/abstracts/search?q=Ratan%20Kulkarni"> Ratan Kulkarni</a>, <a href="https://publications.waset.org/abstracts/search?q=Shaju%20Nair"> Shaju Nair</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With increasing energy costs and its impact on the business, sustainability today has evolved from a social expectation to an economic imperative. Therefore, finding methods to reduce cost has become a critical directive for Industry leaders. Effective energy management is the only way to cut costs. However, Energy Management has been a challenge because it requires a change in old habits and legacy systems followed for decades. Today exorbitant levels of energy and operational data is being captured and stored by Industries, but they are unable to convert these structured and unstructured data sets into meaningful business intelligence. It must be noted that for quick decisions, organizations must learn to cope with large volumes of operational data in different formats. Energy analytics not only helps in extracting inferences from these data sets, but also is instrumental in transformation from old approaches of energy management to new. This in turn assists in effective decision making for implementation. It is the requirement of organizations to have an established corporate strategy for reducing operational costs through visibility and optimization of energy usage. Energy analytics play a key role in optimization of operations. The paper describes how today energy data analytics is extensively used in different scenarios like reducing operational costs, predicting energy demands, optimizing network efficiency, asset maintenance, improving customer insights and device data insights. The paper also highlights how analytics helps transform insights obtained from energy data into sustainable solutions. The paper utilizes data from an array of segments such as retail, transportation, and water sectors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energy%20analytics" title="energy analytics">energy analytics</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20management" title=" energy management"> energy management</a>, <a href="https://publications.waset.org/abstracts/search?q=operational%20data" title=" operational data"> operational data</a>, <a href="https://publications.waset.org/abstracts/search?q=business%20intelligence" title=" business intelligence"> business intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a> </p> <a href="https://publications.waset.org/abstracts/8716/data-analytics-in-energy-management" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8716.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">364</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> Agroforestry Systems and Practices and Its Adoption in Kilombero Cluster of Sagcot, Tanzania</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lazaro%20E.%20Nnko">Lazaro E.

However, their adoption in various regions differs with the biophysical conditions and societal characteristics. This study was conducted in Kilombero District to investigate the factors influencing the adoption of different agroforestry systems and practices in agro-ecosystems and farming systems. A household survey, key informant interviews, and focus group discussion was used for data collection in three villages. Descriptive statistics and multinomial logistic regression in SPSS were applied for analysis. Results show that Igima and Ngajengwa villages had home garden practices dominated, as revealed by 63.3% and 66.7%, respectively, while Mbingu village had mixed intercropping practice with 56.67%. Agrosilvopasture systems were dominant in Igima and Ngajengwa villages with 56.7% and 66.7%, respectively, while in Mbingu village, the dominant system was agrosilviculture with 66.7%. The results from multinomial logistic regression show that different explanatory variable was statistical significance as predictors of the adoption of agroforestry systems and practices. Residence type and sex were the most dominant factor influencing the adoption of agroforestry systems. Duration of stay in the village, availability of extension education, residence, and sex were the dominant factor influencing the adoption of agroforestry practices. The most important and statistically significant factors among these were residence type and sex. The study concludes that agroforestry will be more successful if the local priorities, which include social-economic need characteristics of the society, will be considered in designing systems and practices. The socio-economic need of the community should be addressed in the process of expanding the adoption of agroforestry systems and practices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agroforestry%20adoption" title="agroforestry adoption">agroforestry adoption</a>, <a href="https://publications.waset.org/abstracts/search?q=agroforestry%20systems" title=" agroforestry systems"> agroforestry systems</a>, <a href="https://publications.waset.org/abstracts/search?q=agroforestry%20practices" title=" agroforestry practices"> agroforestry practices</a>, <a href="https://publications.waset.org/abstracts/search?q=agroforestry" title=" agroforestry"> agroforestry</a>, <a href="https://publications.waset.org/abstracts/search?q=Kilombero" title=" Kilombero"> Kilombero</a> </p> <a href="https://publications.waset.org/abstracts/150353/agroforestry-systems-and-practices-and-its-adoption-in-kilombero-cluster-of-sagcot-tanzania" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150353.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">118</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> Orthogonal Metal Cutting Simulation of Steel AISI 1045 via Smoothed Particle Hydrodynamic Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Hamed%20Hashemi%20Sohi">Seyed Hamed Hashemi Sohi</a>, <a href="https://publications.waset.org/abstracts/search?q=Gerald%20Jo%20Denoga"> Gerald Jo Denoga</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Machining or metal cutting is one of the most widely used production processes in industry. The quality of the process and the resulting machined product depends on parameters like tool geometry, material, and cutting conditions. However, the relationships of these parameters to the cutting process are often based mostly on empirical knowledge. In this study, computer modeling and simulation using LS-DYNA software and a Smoothed Particle Hydrodynamic (SPH) methodology, was performed on the orthogonal metal cutting process to analyze three-dimensional deformation of AISI 1045 medium carbon steel during machining. The simulation was performed using the following constitutive models: the Power Law model, the Johnson-Cook model, and the Zerilli-Armstrong models (Z-A). The outcomes were compared against the simulated results obtained by Cenk Kiliçaslan using the Finite Element Method (FEM) and the empirical results of Jaspers and Filice. The analysis shows that the SPH method combined with the Zerilli-Armstrong constitutive model is a viable alternative to simulating the metal cutting process. The tangential force was overestimated by 7%, and the normal force was underestimated by 16% when compared with empirical values. The simulation values for flow stress versus strain at various temperatures were also validated against empirical values. The SPH method using the Z-A model has also proven to be robust against issues of time-scaling. Experimental work was also done to investigate the effects of friction, rake angle and tool tip radius on the simulation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=metal%20cutting" title="metal cutting">metal cutting</a>, <a href="https://publications.waset.org/abstracts/search?q=smoothed%20particle%20hydrodynamics" title=" smoothed particle hydrodynamics"> smoothed particle hydrodynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=constitutive%20models" title=" constitutive models"> constitutive models</a>, <a href="https://publications.waset.org/abstracts/search?q=experimental" title=" experimental"> experimental</a>, <a href="https://publications.waset.org/abstracts/search?q=cutting%20forces%20analyses" title=" cutting forces analyses"> cutting forces analyses</a> </p> <a href="https://publications.waset.org/abstracts/70310/orthogonal-metal-cutting-simulation-of-steel-aisi-1045-via-smoothed-particle-hydrodynamic-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70310.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">261</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">24</span> Evaluating Climate Risks to Enhance Resilience in Durban, South Africa</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cabangile%20Ncengeni%20Ngwane">Cabangile Ncengeni Ngwane</a>, <a href="https://publications.waset.org/abstracts/search?q=Gerald%20Mills"> Gerald Mills</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Anthropogenic climate change is exacerbating natural hazards such as droughts, heat waves and sea-level rise. The associated risks are the greatest in places where socio-ecological systems are exposed to these changes and the populations and infrastructure are vulnerable. Identifying the communities at risk and enhancing local resilience are key issues in responding to the current and project climate changes. This paper explores the types of risks associated with multiple overlapping hazards in Durban, South Africa where the social, cultural and economic dimensions that contribute to exposure and vulnerability are compounded by its history of apartheid. As a result, climate change risks are highly concentrated in marginalized communities that have the least adaptive capacity. In this research, a Geographic Information System is to explore the spatial correspondence among geographic layers representing hazards, exposure and vulnerability across Durban. This quantitative analysis will allow authors to identify communities at high risk and focus our study on the nature of the current human-environment relationships that result in risk inequalities. This work will employ qualitative methods to critically examine policies (including educational practices and financial support systems) and on-the-ground actions that are designed to improve the adaptive capacity of these communities and meet UN Sustainable Development Goals. This work will contribute to a growing body of literature on disaster risk management, especially as it relates to developing economies where socio-economic inequalities are correlated with ethnicity and race. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adaptive%20capacity" title="adaptive capacity">adaptive capacity</a>, <a href="https://publications.waset.org/abstracts/search?q=disaster%20risk%20reduction" title=" disaster risk reduction"> disaster risk reduction</a>, <a href="https://publications.waset.org/abstracts/search?q=exposure" title=" exposure"> exposure</a>, <a href="https://publications.waset.org/abstracts/search?q=resilience" title=" resilience"> resilience</a>, <a href="https://publications.waset.org/abstracts/search?q=South%20Africa" title=" South Africa"> South Africa</a> </p> <a href="https://publications.waset.org/abstracts/145283/evaluating-climate-risks-to-enhance-resilience-in-durban-south-africa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/145283.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">150</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> Empirical Analysis of the Love Languages in the Context of Relationship Satisfaction, Sexual Satisfaction and Empathy in Romantic Heterosexual Couples</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Olha%20Mostova">Olha Mostova</a>, <a href="https://publications.waset.org/abstracts/search?q=Maciej%20Stolarski"> Maciej Stolarski</a>, <a href="https://publications.waset.org/abstracts/search?q=Gerald%20Matthews"> Gerald Matthews</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present paper explores and tests Gary Chapman’s claims that (1) people vary in the ways they prefer to receive and express affection and (2) romantic partners, who communicate their feelings correspondingly to their partner’s preferences, experience greater relationship quality. The author proposes five distinct preferences for and tendencies to express love, including acts of service, physical touch, words of affirmation, quality time, and gifts. In the present study, partners (N = 100 romantic, heterosexual couples) completed measures assessing their preferences and behavioral tendencies reflecting 1) how they a) tend to express and b) prefer to receive signs of affection in correspondence to the five proposed categories; 2) relationship satisfaction; 3) sexual satisfaction and 4) empathy, which was expected to be the factor that leads to a better understanding of and responding to the partner’s needs. The degree of the within-couple match was calculated separately for each individual based on the discrepancies between one’s felt (preferred) and their partner’s expressed love language. The joint discrepancy indicator was a sum of such discrepancies across the five love languages. Conducted analyses provided evidence for significant associations between matching on love languages and both relationship and sexual satisfaction. In particular, people who expressed their affection in the way their partners preferred to receive it experienced greater satisfaction with their relationships and were more sexually satisfied compared to those who met their partner’s needs to a lesser extent. Other results provide some support for mediating effects of certain domains of empathy in the said associations among male but not female participants. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=affection" title="affection">affection</a>, <a href="https://publications.waset.org/abstracts/search?q=empathy" title=" empathy"> empathy</a>, <a href="https://publications.waset.org/abstracts/search?q=love%20languages" title=" love languages"> love languages</a>, <a href="https://publications.waset.org/abstracts/search?q=relationship%20satisfaction" title=" relationship satisfaction"> relationship satisfaction</a>, <a href="https://publications.waset.org/abstracts/search?q=romantic%20couples" title=" romantic couples"> romantic couples</a>, <a href="https://publications.waset.org/abstracts/search?q=sexual%20satisfaction" title=" sexual satisfaction"> sexual satisfaction</a> </p> <a href="https://publications.waset.org/abstracts/134887/empirical-analysis-of-the-love-languages-in-the-context-of-relationship-satisfaction-sexual-satisfaction-and-empathy-in-romantic-heterosexual-couples" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/134887.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">169</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> Associations and Interactions of Delivery Mode and Antibiotic Exposure with Infant Cortisol Level: A Correlational Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samarpreet%20Singh">Samarpreet Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Gerald%20Giesbrecht"> Gerald Giesbrecht</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Both c-section and antibiotic exposure are linked to gut microbiota imbalance in infants. Such disturbance is associated with the Hypothalamic-Pituitary-Adrenal (HPA) axis function. However, the literature only has contradicting evidence for the association between c-sections and the HPA axis. Therefore, this study aims to test if the mode of delivery and antibiotics exposure is associated with the HPA axis. Also, whether exposure to both interacts with the HPA-axis. It was hypothesized that associations and interactions would be observed. Secondary data analysis was used for this co-relational study. Data for the mode of delivery and antibiotics exposure variables were documented from hospital records or self-questionnaires. In addition, cortisol levels (Area under the curve with respect to increasing (AUCi) and Area under the curve with respect to ground (AUCg)) were based on saliva collected from three months old during the infant’s visit to the lab and after drawing blood. One-way and between-subject ANOVA analyses were run on data. No significant association between delivery mode and infant cortisol level was found, AUCi and AUCg, p > .05. Only the infant’s AUCg was found to be significantly higher if there were antibiotics exposure at delivery (p = .001) or their mothers were exposed during pregnancy (p < .05). Infants born by c-section and exposed to antibiotics at three months had higher AUCi than those born vaginally, p < .02. These results imply that antibiotic exposure before three months is associated with an infant’s stress response. The association might increase if antibiotic exposure occurs three months after a c-section birth. However, more robust and causal evidence in future studies is needed, given a variable group’s statistically weak sample size. Nevertheless, the results of this study still highlight the unintended consequences of antibiotic exposure during delivery and pregnancy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=HPA-axis" title="HPA-axis">HPA-axis</a>, <a href="https://publications.waset.org/abstracts/search?q=antibiotics" title=" antibiotics"> antibiotics</a>, <a href="https://publications.waset.org/abstracts/search?q=c-section" title=" c-section"> c-section</a>, <a href="https://publications.waset.org/abstracts/search?q=gut-microbiota" title=" gut-microbiota"> gut-microbiota</a>, <a href="https://publications.waset.org/abstracts/search?q=development" title=" development"> development</a>, <a href="https://publications.waset.org/abstracts/search?q=stress" title=" stress"> stress</a> </p> <a href="https://publications.waset.org/abstracts/168087/associations-and-interactions-of-delivery-mode-and-antibiotic-exposure-with-infant-cortisol-level-a-correlational-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168087.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">72</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> Analysing the Interactive Effects of Factors Influencing Sand Production on Drawdown Time in High Viscosity Reservoirs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gerald%20Gwamba">Gerald Gwamba</a>, <a href="https://publications.waset.org/abstracts/search?q=Bo%20Zhou"> Bo Zhou</a>, <a href="https://publications.waset.org/abstracts/search?q=Yajun%20Song"> Yajun Song</a>, <a href="https://publications.waset.org/abstracts/search?q=Dong%20Changyin"> Dong Changyin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The challenges that sand production presents to the oil and gas industry, particularly while working in poorly consolidated reservoirs, cannot be overstated. From restricting production to blocking production tubing, sand production increases the costs associated with production as it elevates the cost of servicing production equipment over time. Production in reservoirs that present with high viscosities, flow rate, cementation, clay content as well as fine sand contents is even more complex and challenging. As opposed to the one-factor at a-time testing, investigating the interactive effects arising from a combination of several factors offers increased reliability of results as well as representation of actual field conditions. It is thus paramount to investigate the conditions leading to the onset of sanding during production to ensure the future sustainability of hydrocarbon production operations under viscous conditions. We adopt the Design of Experiments (DOE) to analyse, using Taguchi factorial designs, the most significant interactive effects of sanding. We propose an optimized regression model to predict the drawdown time at sand production. The results obtained underscore that reservoirs characterized by varying (high and low) levels of viscosity, flow rate, cementation, clay, and fine sand content have a resulting impact on sand production. The only significant interactive effect recorded arises from the interaction between BD (fine sand content and flow rate), while the main effects included fluid viscosity and cementation, with percentage significances recorded as 31.3%, 37.76%, and 30.94%, respectively. The drawdown time model presented could be useful for predicting the time to reach the maximum drawdown pressure under viscous conditions during the onset of sand production. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=factorial%20designs" title="factorial designs">factorial designs</a>, <a href="https://publications.waset.org/abstracts/search?q=DOE%20optimization" title=" DOE optimization"> DOE optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=sand%20production%20prediction" title=" sand production prediction"> sand production prediction</a>, <a href="https://publications.waset.org/abstracts/search?q=drawdown%20time" title=" drawdown time"> drawdown time</a>, <a href="https://publications.waset.org/abstracts/search?q=regression%20model" title=" regression model"> regression model</a> </p> <a href="https://publications.waset.org/abstracts/156494/analysing-the-interactive-effects-of-factors-influencing-sand-production-on-drawdown-time-in-high-viscosity-reservoirs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156494.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">152</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> Development of Electric Generator and Water Purifier Cart</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Luisito%20L.%20Lacatan">Luisito L.

It is a fact that pure water is precious nowadays and its value is more precious to those who do not have or enjoy it. There are many water filtration products in existence today. However, none of these products fully satisfies the needs of families needing clean drinking water. All of the following products require either large sums of money or extensive maintenance, and some products do not even come with a guarantee of potable water. The proposed project was designed to alleviate the problem of scarcity of potable water in the country and part of the purpose was also to identify the problem or loopholes of the project such as the distance and speed required to produce electricity using a wheel and alternator, the required time for the heating element to heat up, the capacity of the battery to maintain the heat of the heating element and the time required for the boiler to produce a clean and potable water. The project has three parts. The first part included the researchers’ effort to plan every part of the project from the conversion of mechanical energy to electrical energy, from purifying water to potable drinking water to the controller and indicator of the project using microcontroller unit (MCU). This included identifying the problem encountered and any possible solution to prevent and avoid errors. Gathering and reviewing related studies about the project helped the researcher reduce and prevent any problems before they could be encountered. It also included the price and quantity of materials used to control the budget. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mobile" title="mobile">mobile</a>, <a href="https://publications.waset.org/abstracts/search?q=self%20%E2%80%93%20sustaining" title=" self – sustaining"> self – sustaining</a>, <a href="https://publications.waset.org/abstracts/search?q=electricity%20generator" title=" electricity generator"> electricity generator</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20distillation" title=" water distillation"> water distillation</a>, <a href="https://publications.waset.org/abstracts/search?q=wireless%20battery%20indicator" title=" wireless battery indicator"> wireless battery indicator</a>, <a href="https://publications.waset.org/abstracts/search?q=wireless%20water%20level%20indicator" title=" wireless water level indicator"> wireless water level indicator</a> </p> <a href="https://publications.waset.org/abstracts/45555/development-of-electric-generator-and-water-purifier-cart" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45555.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">310</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> Effect of Simulation on Anxiety and Knowledge among Novice Nursing Students</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Suja%20Karkada">Suja Karkada</a>, <a href="https://publications.waset.org/abstracts/search?q=Jayanthi%20Radhakrishnan"> Jayanthi Radhakrishnan</a>, <a href="https://publications.waset.org/abstracts/search?q=Jansi%20Natarajan"> Jansi Natarajan</a>, <a href="https://publications.waset.org/abstracts/search?q=Gerald"> Gerald</a>, <a href="https://publications.waset.org/abstracts/search?q=Amandu%20Matua"> Amandu Matua</a>, <a href="https://publications.waset.org/abstracts/search?q=Sujatha%20Shanmugasundaram"> Sujatha Shanmugasundaram</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Simulation-based learning is an educational strategy designed to simulate actual clinical situations in a safe environment. Globally, simulation is recognized by several landmark studies as an effective teaching-learning method. A systematic review of the literature on simulation revealed simulation as a useful strategy in creating a learning environment which contributes to knowledge, skills, safety, and confidence. However, to the best of the author's knowledge, there are no studies on assessing the anxiety of the students undergoing simulation. Hence the researchers undertook a study with the aim to evaluate the effectiveness of simulation on anxiety and knowledge among novice nursing students. This quasi-experimental study had a total sample of 69 students (35- Intervention group with simulation and 34- Control group with case scenario) consisting of all the students enrolled in the Fundamentals of Nursing Laboratory course during Spring 2016 and Fall 2016 semesters at a college of nursing in Oman. Ethical clearance was obtained from the Institutional Review Board (IRB) of the college of nursing. Informed consent was obtained from every participant. Study received the Dean’s fund for research. The data were collected regarding the demographic information, knowledge and anxiety levels before and after the use of simulation and case scenario for the procedure nasogastric tube feeding in intervention and control group respectively. The intervention was performed by four faculties who were the core team members of the course. Results were analyzed in SPSS using descriptive and inferential statistics. Majority of the students’ in intervention (82.9%) and control (89.9%) groups were equal to or below the age of 20 years, were females (71%), 76.8% of them were from rural areas and 65.2% had a GPA of more than 2.5. The selection of the samples to either the experimental or the control group was from a homogenous population (p > 0.05). There was a significant reduction of anxiety among the students of control group (t (67) = 2.418, p = 0.018) comparing to the experimental group, indicating that simulation creates anxiety among Novice nursing students. However, there was no significant difference in the mean scores of knowledge. In conclusion, the study was useful in that it will help the investigators better understand the implications of using simulation in teaching skills to novice students. Since previous studies with students indicate better knowledge acquisition; this study revealed that simulation can increase anxiety among novice students possibly it is the first time they are introduced to this method of teaching. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anxiety" title="anxiety">anxiety</a>, <a href="https://publications.waset.org/abstracts/search?q=knowledge" title=" knowledge"> knowledge</a>, <a href="https://publications.waset.org/abstracts/search?q=novice%20students" title=" novice students"> novice students</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a> </p> <a href="https://publications.waset.org/abstracts/94733/effect-of-simulation-on-anxiety-and-knowledge-among-novice-nursing-students" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/94733.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">159</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> Miniature Fast Steering Mirrors for Space Optical Communication on NanoSats and CubeSats</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sylvain%20Chardon">Sylvain Chardon</a>, <a href="https://publications.waset.org/abstracts/search?q=Timot%C3%A9o%20Payre"> Timotéo Payre</a>, <a href="https://publications.waset.org/abstracts/search?q=Hugo%20Grardel"> Hugo Grardel</a>, <a href="https://publications.waset.org/abstracts/search?q=Yann%20Quentel"> Yann Quentel</a>, <a href="https://publications.waset.org/abstracts/search?q=Mathieu%20Thomachot"> Mathieu Thomachot</a>, <a href="https://publications.waset.org/abstracts/search?q=G%C3%A9rald%20Aigouy"> Gérald Aigouy</a>, <a href="https://publications.waset.org/abstracts/search?q=Frank%20Claeyssen"> Frank Claeyssen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With the increasing digitalization of society, access to data has become vital and strategic for individuals and nations. In this context, the number of satellite constellation projects is growing drastically worldwide and is a next-generation challenge of the New Space industry. So far, existing satellite constellations have been using radio frequencies (RF) for satellite-to-ground communications, inter-satellite communications, and feeder link communication. However, RF has several limitations, such as limited bandwidth and low protection level. To address these limitations, space optical communication will be the new trend, addressing both very high-speed and secured encrypted communication. Fast Steering Mirrors (FSM) are key components used in optical communication as well as space imagery and for a large field of functions such as Point Ahead Mechanisms (PAM), Raster Scanning, Beam Steering Mirrors (BSM), Fine Pointing Mechanisms (FPM) and Line of Sight stabilization (LOS). The main challenges of space FSM development for optical communication are to propose both a technology and a supply chain relevant for high quantities New Space approach, which requires secured connectivity for high-speed internet, Earth planet observation and monitoring, and mobility applications.

Hart</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The majority of glucose metabolism proceeds through glycolytic pathways such as glycolysis or pentose phosphate pathway, however, about 5% is shunted through the hexosamine biosynthetic pathway, producing uridine diphosphate N-acetyl glucosamine (UDP-GlcNAc). This precursor can then be incorporated into complex oligosaccharides decorating the cell surface or remain as an intracellular post-translational-modification (PTM) of serine/threonine residues (O-GlcNAcylation, OGN), which has been identified on over 4,000 cytosolic or nuclear proteins. Intracellular OGN has major implications on cellularprocesses, typically by modulating protein localization, protein-protein interactions, protein degradation, and gene expression. Additionally, OGN is known to have an extensive cross-talk with phosphorylation, be in a competitive or cooperative manner. Unlike other PTMs there are only two cycling enzymes that are capable of adding or removing the GlcNAc moiety, O-linked N-aceytl glucosamine Transferase (OGT) and O-linked N-acetyl glucoamidase (OGA), respectively. The activity of OGT has been shown to be sensitive to cellular UDP-GlcNAc levels, even changing substrate affinity. Owing to this and that the concentration of UDP-GlcNAc is related to the metabolisms of glucose, amino acid, fatty acid, and nucleotides, O-GlcNAc is often referred to as a nutrient sensing rheostat. Indeed OGN is known to regulate several signaling pathways as a result of nutrient levels, such as insulin signaling. Dysregulation of OGN is associated with several disease states such as cancer, diabetes, and neurodegeneration. Improvements in glycomics over the past 10-15 years has significantly increased the OGT substrate pool, suggesting O-GlcNAc’s involvement in a wide variety of signaling pathways. However, O-GlcNAc’s role at the receptor level has only been identified in a case-by-case basis of known pathways. Examining the OGN of the plasma membrane (PM) may better focus our understanding of O-GlcNAc-effected signaling pathways. In this current study, PM fractions were isolated from several cell types via ultracentrifugation, followed by purification and MS/MS analysis in several cell lines. This process was repeated with or without OGT/OGA inhibitors or with increased/decreased glucose levels in media to ascertain the importance of OGN. Various pathways are followed up on in more detailed studies employing methods to localize OGN at the PM specifically. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=GlcNAc" title="GlcNAc">GlcNAc</a>, <a href="https://publications.waset.org/abstracts/search?q=nutrient%20sensitive" title=" nutrient sensitive"> nutrient sensitive</a>, <a href="https://publications.waset.org/abstracts/search?q=post-translational-modification" title=" post-translational-modification"> post-translational-modification</a>, <a href="https://publications.waset.org/abstracts/search?q=receptor" title=" receptor"> receptor</a> </p> <a href="https://publications.waset.org/abstracts/154198/identification-of-nutrient-sensitive-signaling-pathways-via-analysis-of-o-glcnacylation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154198.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">112</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> Towards Sustainable African Urban Design Concepts</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gerald%20Steyn">Gerald Steyn</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Sub-Saharan Africa is the world's fastest urbanizing region, but approximately 60 to 70 percent of urban African households are poor and living in slums. Although influential global institutions such as the World Bank propagate a new approach to housing and land policies, sustainable African urban concepts have yet to be applied significantly or even convincingly conceptualized. Most African city planners, urban designers, architects, policymakers, and developers have been trained in Western curriculums and continue to practice and plan according to such formal paradigms. Only a few activists promote Post-Colonial Afrocentric urbanism, recognizing the imperative of foregrounding the needs of low-income people. There is a vast body of authoritative literature on analyzing poverty and slums in sub-Saharan Africa and on promoting the need for land and city planning reform. However, of the latter, only a few venture beyond advising and sometimes outlining policy changes. The current study moves beyond a purely theoretical discourse into the realm of practice by designing replicable diagrammatic concepts at different urban scales. The guiding philosophy was that land-use concepts and urban requirements favoring low-income households must be fully integrated into the larger conurbation. Information was derived from intensive research over two decades, involving literature surveys and observations during regular travels into East and Southern Africa. Appropriate existing urban patterns, particularly vernacular and informal, were subsequently analyzed and reimagined as precedents to inform and underpin the represented design concepts. Five interrelated concepts are proposed, ranging in scale from (1) regional to (2) cities and (3) urban villages to (4) neighborhoods and (5) streets. Each concept is described, first in terms of its context and associated issues of concern, followed by a discussion of the patterns available to inform a possible solution, and finally, an explanation and graphic illustration of the proposal. Since each of the five concepts is unfolded from existing informal and vernacular practices studied in situ, the approach is entirely bottom-up. Contrary to an idealized vision of the African city, this study proposes actual concepts for critical assessment by peers in the tradition of architectural research in design. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=african%20urban%20concepts" title="african urban concepts">african urban concepts</a>, <a href="https://publications.waset.org/abstracts/search?q=post-colonial%20afrocentric%20urbanism" title=" post-colonial afrocentric urbanism"> post-colonial afrocentric urbanism</a>, <a href="https://publications.waset.org/abstracts/search?q=sub-saharan%20africa" title=" sub-saharan africa"> sub-saharan africa</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20african%20urban%20design" title=" sustainable african urban design"> sustainable african urban design</a> </p> <a href="https://publications.waset.org/abstracts/185176/towards-sustainable-african-urban-design-concepts" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185176.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">50</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> Prevalence of Adverse Events in Children and Adolescents on Antiretroviral Therapy: Examining the Pediatric Cohort in the Eastern Cape</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shannon%20Glaspy">Shannon Glaspy</a>, <a href="https://publications.waset.org/abstracts/search?q=Gerald%20Boon"> Gerald Boon</a>, <a href="https://publications.waset.org/abstracts/search?q=Jack%20Lambert"> Jack Lambert</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Studies on AE of highly active antiretroviral therapy (HAART) in children and adolescents are rare. The aim of this study is to observe the frequency of treatment limiting adverse drug reactions against years on ARVs and specific ARV regimen. Methods: A retrospective cohort study was conducted in East London, South Africa. All patient files in the pediatric (0 – 18 years) ARV cohort were examined, selecting only those patients started on HAART. ARV regimen changes explicitly due to AE, age on ARV treatment onset, age of AE onset, and gender were extrapolated. Eligible subjects were obtained from patient folders, anonymized and cross-referenced with data obtained from electronic records. A total of 1120 patients [592 male (52.9%) and 528 female (47.1%)] were charted by incidence and year. Additional information was extrapolated in cases where the patient experienced lipodystrophy and lipoatrophy to include the number of years on ARVs prior to the onset of the AE. Results: Of the 1120 HIV infected children of the hospital cohort, a total of 105 (9.37%) AE (53.3% male) observed were deemed eligible for the study due to completeness of medical history and agreement between electronic records and paper files. The AE cited were as follows: lipoatrophy 62 (5.53% of all subjects), lipodystrophy 27 (2.41%), neuropathy 9 (0.8%), anemia 2 (0.17%), Steven Johnsons Syndrome 1 (0.08%), elevated LFTs 1 (0.8%), breast hypertrophy (0.08%), gastritis 1 (0.08%) and rash 1 (0.08%). The most prevalence ARV regimens associated with the onset of the AE are: D4T/3TC/EFV 72 cases (64.86% of all AE), D4T/3TC/LOPr 24 cases (21.62%). Lipoatrophy and lipodystrophy combined represent 84.76% (89 cases) of all adverse events documented in this cohort. Within the 60 cases of lipoatrophy, the average number of years on ARVs associated with an AE is 3.54, with 14 cases experiencing an AE between 0-2 years of HAART. Within the 29 cases of lipodystrophy, the average number of years on ARVs associated with an AE is 3.89, with 4 cases experiencing an AE between 0-2 years on HAART. The regimen D4T/3TC/EFV is associated with 43 cases (71.66%) of lipoatrophy and 21 cases (72.41%) of lipodystrophy. D4T/3TC/LOPr is associated with 15 cases (25%) of lipoatrophy and 7 cases (24.14%) of lipodystrophy. The frequency of AE associated with ARV regimens could be misrepresented due to prevalence of different 1st line regimens which were not captured in this study, particularly with the systematic change of 1st line drugs from D4T to ABC in 2010. Conclusion: In this descriptive study we found a 9.37% prevalence of AE were significant enough to be treatment limiting among our cohort. Lipoatrophy accounted for 59.04% of all documented AE. Overall, D4T/3TC/EFV was associated with 64.86% of all AE, 71.66% of lipoatrophy cases and 72.41% of lipodystrophy cases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ARV" title="ARV">ARV</a>, <a href="https://publications.waset.org/abstracts/search?q=adverse%20events" title=" adverse events"> adverse events</a>, <a href="https://publications.waset.org/abstracts/search?q=HAART" title=" HAART"> HAART</a>, <a href="https://publications.waset.org/abstracts/search?q=pediatric" title=" pediatric"> pediatric</a> </p> <a href="https://publications.waset.org/abstracts/73310/prevalence-of-adverse-events-in-children-and-adolescents-on-antiretroviral-therapy-examining-the-pediatric-cohort-in-the-eastern-cape" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73310.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">14</span> Incorporation of Noncanonical Amino Acids into Hard-to-Express Antibody Fragments: Expression and Characterization</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hana%20Hanaee-Ahvaz">Hana Hanaee-Ahvaz</a>, <a href="https://publications.waset.org/abstracts/search?q=Monika%20Cserjan-Puschmann"> Monika Cserjan-Puschmann</a>, <a href="https://publications.waset.org/abstracts/search?q=Christopher%20Tauer"> Christopher Tauer</a>, <a href="https://publications.waset.org/abstracts/search?q=Gerald%20Striedner"> Gerald Striedner</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Incorporation of noncanonical amino acids (ncAA) into proteins has become an interesting topic as proteins featured with ncAAs offer a wide range of different applications. Nowadays, technologies and systems exist that allow for the site-specific introduction of ncAAs in vivo, but the efficient production of proteins modified this way is still a big challenge. This is especially true for 'hard-to-express' proteins where low yields are encountered even with the native sequence. In this study, site-specific incorporation of azido-ethoxy-carbonyl-Lysin (azk) into an anti-tumor-necrosis-factor-α-Fab (FTN2) was investigated. According to well-established parameters, possible site positions for ncAA incorporation were determined, and corresponding FTN2 genes were constructed. Each of the modified FTN2 variants has one amber codon for azk incorporated either in its heavy or light chain. The expression level for all variants produced was determined by ELISA, and all azk variants could be produced with a satisfactory yield in the range of 50-70% of the original FTN2 variant. In terms of expression yield, neither the azk incorporation position nor the subunit modified (heavy or light chain) had a significant effect. We confirmed correct protein processing and azk incorporation by mass spectrometry analysis, and antigen-antibody interaction was determined by surface plasmon resonance analysis. The next step is to characterize the effect of azk incorporation on protein stability and aggregation tendency via differential scanning calorimetry and light scattering, respectively. In summary, the incorporation of ncAA into our Fab candidate FTN2 worked better than expected. The quantities produced allowed a detailed characterization of the variants in terms of their properties, and we can now turn our attention to potential applications. By using click chemistry, we can equip the Fabs with additional functionalities and make them suitable for a wide range of applications. We will now use this option in a first approach and develop an assay that will allow us to follow the degradation of the recombinant target protein in vivo. Special focus will be laid on the proteolytic activity in the periplasm and how it is influenced by cultivation/induction conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=degradation" title="degradation">degradation</a>, <a href="https://publications.waset.org/abstracts/search?q=FTN2" title=" FTN2"> FTN2</a>, <a href="https://publications.waset.org/abstracts/search?q=hard-to-express%20protein" title=" hard-to-express protein"> hard-to-express protein</a>, <a href="https://publications.waset.org/abstracts/search?q=non-canonical%20amino%20acids" title=" non-canonical amino acids"> non-canonical amino acids</a> </p> <a href="https://publications.waset.org/abstracts/138030/incorporation-of-noncanonical-amino-acids-into-hard-to-express-antibody-fragments-expression-and-characterization" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/138030.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">233</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> Fast-Tracking University Education for Youth Employment: Empirical Evidence from University Graduates in Rwanda </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fred%20Alinda">Fred Alinda</a>, <a href="https://publications.waset.org/abstracts/search?q=Marjorie%20Negesa"> Marjorie Negesa</a>, <a href="https://publications.waset.org/abstracts/search?q=Gerald%20Karyeija"> Gerald Karyeija</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Like elsewhere in the world, youth unemployment remains a big problem more so to the most educated youth and female. In Rwanda, unemployment is estimated at 13.2% among youth graduates compared to 10.9% and 2.6 among secondary and primary graduates respectively. Though empirical evidence elsewhere associate youth unemployment with education level, relevance of skills and access to business support opportunities, mixed evidence still exist on the significance of these factors to youth employment. As youth employment strategies in countries like Rwanda continue to recognize the potential role university education can play to enhance employment, there is a need to understand the catalysts or barriers. This paper, therefore, draws empirical evidence from a survey on the influence of education qualification, skills relevance and access to business support opportunities on employment of the youth university graduates in Masaka sector, Rwanda. The analysis tested four hypotheses; access to university education significantly affects youth employment, Relevance of university education significantly contributes to youth employment; access to business support opportunities significantly contributes to youth employment, and significant gender differences exist in the employment of youth university graduates. A cross-section survey was used in lieu of the need to explore the prevailing status of youth employment and contributing factors across the sector. A questionnaire was used to collect data on a large sample of 269 youth to allow statistical analysis. This was beefed up with qualitative views of leaders and technical officials in the sector. The youth University graduates were selected using simple random sampling while the leaders and technical officials were selected purposively. Percentages were used to describe respondents in line with the variables under while a regression model for youth employment was fitted to determine the significant factors. The model results indicated a significant influence (p<0.05) of gender, education level and access to business support opportunities on employment of youth university graduates. This finding was also affirmed by the qualitative views of key informants. Qualitative views pointed to the fact that university education generally equipped the youth with skills that enabled their transition into employment mainly for a salary or wage. The skills were, however, deficient in technical and practical aspects. In addition, the youth generally lacked limited access to business support opportunities particularly guarantees for loans, business advisory, and grants for business as well as training in business skills that would help them gain salaried employment or transit into self-employment. The study findings bear an implication on the strategy for catalyzing youth employment through university education. The findings imply that university education should be embraced but with greater emphasis on or supplementation with specialized training in practical and technical skills as well as extending business support opportunities to the youth. This will accelerate the contribution of university education to youth employment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=education"
