Since the hand is in constant contact with fomites which have been proven to be mostly contaminated, building hand hygiene habits is essential for the prevention of infection. This research was conducted to assess the hand hygiene habits of Ghanaian youths in Accra. This study used a survey as a quantitative method of research. The findings of the study revealed that out of the 254 participants who fully answered the questionnaire, 22% had the habit of washing their hands after outings while only 51.6% had the habit of washing their hands after using the bathroom. However, about 60% of the participants said they sometimes ate with their hands while 28.9% had the habit of eating with the hand very often, a situation that put them at risk of infection from their hands since some participants had poor handwashing habits; prompting the need for continuous education on hand hygiene. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hand%20hygiene" title="hand hygiene">hand hygiene</a>, <a href="https://publications.waset.org/abstracts/search?q=hand%20hygiene%20habit" title=" hand hygiene habit"> hand hygiene habit</a>, <a href="https://publications.waset.org/abstracts/search?q=hand%20washing" title=" hand washing"> hand washing</a>, <a href="https://publications.waset.org/abstracts/search?q=hand%20sanitizer%20use" title=" hand sanitizer use"> hand sanitizer use</a> </p> <a href="https://publications.waset.org/abstracts/159334/hand-hygiene-habits-of-ghanaian-youths-in-accra" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159334.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">108</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">79</span> A Study on the Motivational Factors of Women Entrepreneurship</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gladys%20Oppong">Gladys Oppong</a>, <a href="https://publications.waset.org/abstracts/search?q=Saumya%20Singh"> Saumya Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Pramod%20Pathak"> Pramod Pathak</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Women entrepreneurship has started establishing itself globally. Despite various social hurdles, Indian women have proved their strength in the area of entrepreneurship. Rising pattern of women entrepreneurship in Indian context make it significant to know the reason behind it. It’s a normal perception that women with financially strong backgrounds are highly motivated to progress in the area of entrepreneurship while lack of money becomes a major restraint for others. The proposed study attempts to identify the motivational factors for becoming women entrepreneur. The research work is to be conducted on women entrepreneurs. For this purpose, factor analysis will be used. The study has identified a set of motivational factors namely family business, social status, education and qualification, self-fulfillment and achievement among others that give momentum to the women to become an entrepreneur. The outcome of the study will be helpful in developing women entrepreneurship in India. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=women%20entrepreneurship" title="women entrepreneurship">women entrepreneurship</a>, <a href="https://publications.waset.org/abstracts/search?q=motivation" title=" motivation"> motivation</a>, <a href="https://publications.waset.org/abstracts/search?q=family%20business" title=" family business"> family business</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20status" title=" social status"> social status</a> </p> <a href="https://publications.waset.org/abstracts/88584/a-study-on-the-motivational-factors-of-women-entrepreneurship" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88584.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">345</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">78</span> The Effects of Land Grabbing on Livelihood Assets and Its Implication on Food Production in Ghana: A Case Study of Bui Dam Construction Project</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Charles%20Kwaku%20Oppong">Charles Kwaku Oppong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study examined the effects of the agricultural land grabbed for the Bui Dam project on the livelihoods assets of the affected people and its implication on food production. Both quantitative and qualitative data were collected through the use of focus group discussions, questionnaire administration, interview guide, and observations. It was found that the land grabbing incident in the study communities as a result of the Bui Dam construction has resulted in the improvements in the physical assets of the affected people. The findings also indicated that local food crop production and the quantity of fish catch have dwindled after the land grabs. Contrary to this, the local people’s access to the natural capital, particularly the local land for agricultural activities has been worsened. The study recommends alternative sustainable livelihood for the affected people by the local government. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=land%20grabbing" title="land grabbing">land grabbing</a>, <a href="https://publications.waset.org/abstracts/search?q=livelihood" title=" livelihood"> livelihood</a>, <a href="https://publications.waset.org/abstracts/search?q=asset" title=" asset"> asset</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20production" title=" food production"> food production</a> </p> <a href="https://publications.waset.org/abstracts/102607/the-effects-of-land-grabbing-on-livelihood-assets-and-its-implication-on-food-production-in-ghana-a-case-study-of-bui-dam-construction-project" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/102607.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">77</span> The Effects of Urbanization on Peri-Urban Livelihood in Ghana: A Case of Kumasi Peri-Urban Communities</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Charles%20Kwaku%20Oppong">Charles Kwaku Oppong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The research linked urban expansion resulting from urbanization with changing morphology processes happening in peri-urban communities. Two villages of Kumasi City peri-urban were used as a case study. Appropriate analytical framework and methodology (literature review and empirical evidence) were employed to ensure that all pertinent issues of peri-urban interface are brought to light. It was discovered from the study that since peri-urban livelihood is linked with assets base; it has been found that stock of asset, as well as transformation processes, were major factors in the shaping of livelihoods strategies. For that reason, success or failure of household livelihoods was seen to relate to the kind of livelihood strategy employed. With efforts to mitigate for livelihoods failure due to peri-urban development, households' recourse to remittances, land disposal, and other means as an alternative livelihood approach. The study calls for local government policy interventions in regulating peri-urban transformation process and providing safety nets for the vulnerable. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=urban%20expansion" title="urban expansion">urban expansion</a>, <a href="https://publications.waset.org/abstracts/search?q=peri-urban%20interface" title=" peri-urban interface"> peri-urban interface</a>, <a href="https://publications.waset.org/abstracts/search?q=livelihoods" title=" livelihoods"> livelihoods</a>, <a href="https://publications.waset.org/abstracts/search?q=asset" title=" asset"> asset</a> </p> <a href="https://publications.waset.org/abstracts/102321/the-effects-of-urbanization-on-peri-urban-livelihood-in-ghana-a-case-of-kumasi-peri-urban-communities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/102321.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">265</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">76</span> Graffiti as Intelligence: an Analysis of Encoded Messages in Gang Graffiti Renderings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Timothy%20Kephart">Timothy Kephart</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Many law enforcement officials believe that gangs communicate messages to both the community and to rival gangs through graffiti. Some social scientists have documented this as well, however no recent research has examined gang graffiti for its underlying meaning. Empirical research on gang graffiti and gang communication through graffiti is limited. This research can be described as an exploratory effort to better understand how, and perhaps why, gangs employ this medium for communication. Furthermore this research showcases how law enforcement agencies can utilize this hidden form of communication to better direct resources and impact gang violence. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gangs" title="gangs">gangs</a>, <a href="https://publications.waset.org/abstracts/search?q=graffiti" title=" graffiti"> graffiti</a>, <a href="https://publications.waset.org/abstracts/search?q=juvenile%20justice" title=" juvenile justice"> juvenile justice</a>, <a href="https://publications.waset.org/abstracts/search?q=policing" title=" policing"> policing</a> </p> <a href="https://publications.waset.org/abstracts/28825/graffiti-as-intelligence-an-analysis-of-encoded-messages-in-gang-graffiti-renderings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28825.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">439</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">75</span> The Biomechanical Consequences of Pes Planus</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mariette%20Swanepoel">Mariette Swanepoel</a>, <a href="https://publications.waset.org/abstracts/search?q=Terry%20Ellapen"> Terry Ellapen</a>, <a href="https://publications.waset.org/abstracts/search?q=Henriette%20Hammil"> Henriette Hammil</a>, <a href="https://publications.waset.org/abstracts/search?q=Juandre%20Williams"> Juandre Williams</a>, <a href="https://publications.waset.org/abstracts/search?q=Timothy%20Qumbu"> Timothy Qumbu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The biomechanical consequence of pes planus is a topic seldom reviewed in regards to energy expenditure and predisposition to injury.

This study was conducted to assess the factors associated with rural-urban migration and its associated health hazards among female adolescents. A sample size of two hundred (200) was chosen in which all responded to questionnaires comprising closed-ended questions, which were distributed to gather data from the respondents, after which it was analyzed using the Statistical Package for Social Sciences (SPSS) version 20. The utilized three causes of rural-urban migration thus political, economic and socio-cultural. The study revealed that political situations such as regional inequality (65.4%) and ethnic conflicts (78.2%) whereas economic factors such as lack of amenities (82.3%), lack of employment in rural communities (77.4%), lack of education (74%), and poverty (85.3%) as well as socio-cultural factors such as divorced parents (65.6%), media influence (79.1%), family conflicts (59.4%) and appealing urban informal sector (65.2%) are major causes of migration. Respondents’ encountered challenges such as poor remuneration for services (87.2%), being maltreated by a colleague or worker (69%), sleeping in open space (73.3%), and harassment by the task force (71.4%) and teenage pregnancies (58.5%). The study concluded that the three variables play a key role in adolescent migration and when they travel they end up getting involved in serious health hazardous behaviors such as rapes as well as physical and psychological harassments’. The study, therefore, recommends that vocational training of the rural people on small scale industries (non-farm) activities that could generate an income for the rural household should be introduced. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rural" title="rural">rural</a>, <a href="https://publications.waset.org/abstracts/search?q=urban" title=" urban"> urban</a>, <a href="https://publications.waset.org/abstracts/search?q=migration" title=" migration"> migration</a>, <a href="https://publications.waset.org/abstracts/search?q=female%20health%20hazards" title=" female health hazards"> female health hazards</a> </p> <a href="https://publications.waset.org/abstracts/134074/factors-associated-with-rural-urban-migration-and-its-associated-health-hazards-on-the-female-adolescents-in-kumasi-metropolis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/134074.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">132</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">73</span> Producing Lutein Powder from Algae by Extraction and Drying</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zexin%20Lei">Zexin Lei</a>, <a href="https://publications.waset.org/abstracts/search?q=Timothy%20Langrish"> Timothy Langrish </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Lutein is a type of carotene believed to be beneficial to the eyes. This study aims to explore the possibility of using a closed cycle spray drying system to produce lutein. The system contains a spray dryer, a condenser, a heater, and a pressure seal. Hexane, ethanol, and isopropanol will be used as organic solvents to compare the extraction effects. Several physical and chemical methods of cell disruption will be compared. By continuously sweeping the system with nitrogen, the oxygen content will be controlled below 2%, reducing the concentration of organic solvent below the explosion limit and preventing lutein from being oxidized. Lutein powder will be recovered in the collection device. The volatile organic solvent will be cooled in the condenser and deposited in the bottom until it is discharged from the bottom of the condenser. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=closed%20cycle%20spray%20drying%20system" title="closed cycle spray drying system">closed cycle spray drying system</a>, <a href="https://publications.waset.org/abstracts/search?q=Chlorella%20vulgaris" title=" Chlorella vulgaris"> Chlorella vulgaris</a>, <a href="https://publications.waset.org/abstracts/search?q=organic%20solvent" title=" organic solvent"> organic solvent</a>, <a href="https://publications.waset.org/abstracts/search?q=solvent%20recovery" title=" solvent recovery"> solvent recovery</a> </p> <a href="https://publications.waset.org/abstracts/120838/producing-lutein-powder-from-algae-by-extraction-and-drying" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/120838.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">137</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">72</span> Students’ Post COVID-19 Experiences with E-Learning Platforms among Undergraduate Students of Public Universities in the Ashanti Region, Ghana</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Michael%20Oppong">Michael Oppong</a>, <a href="https://publications.waset.org/abstracts/search?q=Stephanie%20Owusu%20Ansah"> Stephanie Owusu Ansah</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Ofori"> Daniel Ofori</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study investigated students’ post-covid-19 experiences with e-learning platforms among undergraduate students of public universities in the Ashanti region of Ghana. The study respectively drew 289 respondents from two public universities, i.e., Kwame Nkrumah University of Science and Technology (KNUST) Business School and the Kumasi Technical University (KsTU) Business School in Ghana. Given that the population from the two public universities was fairly high, sampling had to be done. The overall population of the study was 480 students randomly sampled from the two public universities using the sampling ratio given by Alreck and Settle (2004). The population constituted 360 students from the Kwame Nkrumah University of Science and Technology (KNUST) Business School and 120 from the Kumasi Technical University Business School (KsTU). The study employed questionnaires as a data collection tool. The data gathered were 289 responses out of 480 questionnaires administered, representing 60.2%. The data was analyzed using pie charts, bar charts, percentages, and line graphs. Findings revealed that the e-learning platforms were still useful. However, the students used it on a weekly basis post-COVID-19, unlike in the COVID-19 era, where it was used daily. All other academic activities, with the exception of examinations, are still undertaken on the e-learning platforms; however, it is underutilized in the post-COVID-19 experience. The study recommends that universities should invest in infrastructure development to enable all academic activities, most especially examinations, to be undertaken using the e-learning platforms to curtail future challenges. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=e-learning%20platform" title="e-learning platform">e-learning platform</a>, <a href="https://publications.waset.org/abstracts/search?q=undergraduate%20students" title=" undergraduate students"> undergraduate students</a>, <a href="https://publications.waset.org/abstracts/search?q=post-COVID-19%20experience" title=" post-COVID-19 experience"> post-COVID-19 experience</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20universities" title=" public universities"> public universities</a> </p> <a href="https://publications.waset.org/abstracts/155561/students-post-covid-19-experiences-with-e-learning-platforms-among-undergraduate-students-of-public-universities-in-the-ashanti-region-ghana" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155561.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">97</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">71</span> Storage System Validation Study for Raw Cocoa Beans Using Minitab® 17 and R (R-3.3.1)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anthony%20Oppong%20Kyekyeku">Anthony Oppong Kyekyeku</a>, <a href="https://publications.waset.org/abstracts/search?q=Sussana%20Antwi-Boasiako"> Sussana Antwi-Boasiako</a>, <a href="https://publications.waset.org/abstracts/search?q=Emmanuel%20De-Graft%20Johnson%20Owusu%20Ansah"> Emmanuel De-Graft Johnson Owusu Ansah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this observational study, the performance of a known conventional storage system was tested and evaluated for fitness for its intended purpose. The system has a scope extended for the storage of dry cocoa beans. System sensitivity, reproducibility and uncertainties are not known in details. This study discusses the system performance in the context of existing literature on factors that influence the quality of cocoa beans during storage. Controlled conditions were defined precisely for the system to give reliable base line within specific established procedures. Minitab® 17 and R statistical software (R-3.3.1) were used for the statistical analyses. The approach to the storage system testing was to observe and compare through laboratory test methods the quality of the cocoa beans samples before and after storage. The samples were kept in Kilner jars and the temperature of the storage environment controlled and monitored over a period of 408 days. Standard test methods use in international trade of cocoa such as the cut test analysis, moisture determination with Aqua boy KAM III model and bean count determination were used for quality assessment. The data analysis assumed the entire population as a sample in order to establish a reliable baseline to the data collected. The study concluded a statistically significant mean value at 95% Confidence Interval (CI) for the performance data analysed before and after storage for all variables observed. Correlational graphs showed a strong positive correlation for all variables investigated with the exception of All Other Defect (AOD). The weak relationship between the before and after data for AOD had an explained variability of 51.8% with the unexplained variability attributable to the uncontrolled condition of hidden infestation before storage. The current study concluded with a high-performance criterion for the storage system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=benchmarking%20performance%20data" title="benchmarking performance data">benchmarking performance data</a>, <a href="https://publications.waset.org/abstracts/search?q=cocoa%20beans" title=" cocoa beans"> cocoa beans</a>, <a href="https://publications.waset.org/abstracts/search?q=hidden%20infestation" title=" hidden infestation"> hidden infestation</a>, <a href="https://publications.waset.org/abstracts/search?q=storage%20system%20validation" title=" storage system validation"> storage system validation</a> </p> <a href="https://publications.waset.org/abstracts/83520/storage-system-validation-study-for-raw-cocoa-beans-using-minitab-17-and-r-r-331" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83520.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">174</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">70</span> Analysis of Initial Entry-Level Technology Course Impacts on STEM Major Selection</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ethan%20Shafer">Ethan Shafer</a>, <a href="https://publications.waset.org/abstracts/search?q=Timothy%20Graziano"> Timothy Graziano</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research seeks to answer whether first-year courses at institutions of higher learning can impact STEM major selection. Unlike many universities, an entry-level technology course (often referred to as CS0) is required for all United States Military Academy (USMA) students–regardless of major–in their first year of attendance. Students at the academy choose their major at the end of their first year of studies. Through student responses to a multi-semester survey, this paper identifies a number of factors that potentially influence STEM major selection. Student demographic data, pre-existing exposure and access to technology, perceptions of STEM subjects, and initial desire for a STEM major are captured before and after taking a CS0 course. An analysis of factors that contribute to student perception of STEM and major selection are presented. This work provides recommendations and suggestions for institutions currently providing or looking to provide CS0-like courses to their students. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=education" title="education">education</a>, <a href="https://publications.waset.org/abstracts/search?q=STEM" title=" STEM"> STEM</a>, <a href="https://publications.waset.org/abstracts/search?q=pedagogy" title=" pedagogy"> pedagogy</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20literacy" title=" digital literacy"> digital literacy</a> </p> <a href="https://publications.waset.org/abstracts/156548/analysis-of-initial-entry-level-technology-course-impacts-on-stem-major-selection" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156548.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">121</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">69</span> A Theoretical and Corpus-Based Analysis of English and Spanish Syntax Derived from Método de Los Relojes Verb Types According to Systemic-Functional Grammar as a Foundation for Methodological Adaption</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Timothy%20William%20Lawrence">Timothy William Lawrence</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The goal of this paper is to research and categorize the four basic verb types found in the Spanish descriptive grammar book Método de los Relojes using verb clauses as representation as found in M.A.K.

Compartmental models are most efficient for calculating the infectious potential of a disease. In this paper, we discuss and profile epidemiologically relevant data features from a Domain Name System (DNS) dataset. We then apply these features to epidemiological compartmental models to network traffic features. This paper demonstrates how epidemiological principles can be applied to the novel analysis of key cybersecurity behaviours and trends and provides insight into threat modelling above that of kill-chain analysis. In applying deterministic compartmental models to a cyber security use case, the authors analyse the deficiencies and provide an enhanced stochastic model for cyber epidemiology. This enhanced compartmental model (SUEICRN model) is contrasted with the traditional SEIR model to demonstrate its efficacy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cybersecurity" title="cybersecurity">cybersecurity</a>, <a href="https://publications.waset.org/abstracts/search?q=epidemiology" title=" epidemiology"> epidemiology</a>, <a href="https://publications.waset.org/abstracts/search?q=cyber%20epidemiology" title=" cyber epidemiology"> cyber epidemiology</a>, <a href="https://publications.waset.org/abstracts/search?q=malware" title=" malware"> malware</a> </p> <a href="https://publications.waset.org/abstracts/152584/towards-an-enhanced-compartmental-model-for-profiling-malware-dynamics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152584.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">107</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">67</span> Predictors and Prevention of Sports’ Injuries among Male Professional Footballers in Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Timothy%20A.%20Oloyede">Timothy A.

It is believed that the friction between the runners and ice significantly contributes to the amount of the total energy loss during a bob skeleton descent. There is only limited available experimental data regarding the friction of bob skeleton runners or indeed steel on the ice at high sliding speeds ( > 20 m/s). Testing methods used to investigate the friction of steel on ice in winter sports have been outlined, and their accuracy and repeatability discussed. A system thinking approach was used to investigate the runner-ice interaction during sliding and create concept designs of three ice tribometers. The operational envelope of the bob skeleton system has been defined through mathematical modelling. Designs of a drum, linear and inertia pin-on-disk tribometers were developed specifically for bob skeleton runner testing with the requirement of reaching up to 40 m/s speed and facilitate fresh ice sliding. The design constraints have been outline and the proposed solutions compared based on the ease of operation, accuracy and the development cost. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bob%20skeleton" title="bob skeleton">bob skeleton</a>, <a href="https://publications.waset.org/abstracts/search?q=ice%20friction" title=" ice friction"> ice friction</a>, <a href="https://publications.waset.org/abstracts/search?q=high-speed%20tribometers" title=" high-speed tribometers"> high-speed tribometers</a>, <a href="https://publications.waset.org/abstracts/search?q=sliding%20friction" title=" sliding friction"> sliding friction</a> </p> <a href="https://publications.waset.org/abstracts/72268/assessment-of-the-high-speed-ice-friction-of-bob-skeleton-runners" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72268.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">261</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">65</span> The Application of Maintenance Strategy in Energy Power Plant: A Case Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Steven%20Vusmuzi%20Mashego">Steven Vusmuzi Mashego</a>, <a href="https://publications.waset.org/abstracts/search?q=Opeyeolu%20Timothy%20Laseinde"> Opeyeolu Timothy Laseinde</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a case study on applying maintenance strategies observed in a turbo-generator at a coal power plant.

A high temperature can lead to voltage losses of solar panels, whereas a low temperature can cause voltage overproduction. There are two possible scenarios of the inverter’s operation in which they are associated with the erroneous calculations of the number of PV panels: 1) If the number of the panels is scant and the temperature is high, the minimum voltage required to operate the inverter will not be reached. As a result, the inverter will shut down. 2) Comparably, if the number of panels is excessive and the temperature is low, the produced voltage will be more than the maximum limit of the inverter which can cause the inverter to get disconnected or even damaged. This article aims to assess theoretical and practical methodologies to calculate size and determine the topology of a PV array. The results are validated by applying an experimental evaluation for a 100 kW Grid-connected PV system for a location in Halifax, Nova Scotia and achieving a satisfactory system performance compared to the previous work done. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sizing%20PV%20panels" title="sizing PV panels">sizing PV panels</a>, <a href="https://publications.waset.org/abstracts/search?q=theoretical%20and%20practical%20methodologies" title=" theoretical and practical methodologies"> theoretical and practical methodologies</a>, <a href="https://publications.waset.org/abstracts/search?q=topology%20of%20PV%20array" title=" topology of PV array"> topology of PV array</a>, <a href="https://publications.waset.org/abstracts/search?q=grid-connected%20PV" title=" grid-connected PV"> grid-connected PV</a> </p> <a href="https://publications.waset.org/abstracts/130722/grid-connected-photovoltaic-system-system-overview-and-sizing-principles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130722.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">365</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">62</span> Doing Cause-and-Effect Analysis Using an Innovative Chat-Based Focus Group Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Timothy%20Whitehill">Timothy Whitehill</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents an innovative chat-based focus group method for collecting qualitative data to construct a cause-and-effect analysis in business research.

Against this backdrop, this study examines the nexus between corporate governance and performance of firms from 2012 to 2020, using the case study of the Nigerian stock exchange. Consequently, data was collected from forty (40) listed firms on the Nigerian Stock Exchange. The study employed a fixed effect technique of estimation to address the objective of the study. It was discovered from the study that the influence of corporate governance components such as gender diversity, board independence and managerial ownership led to a significant positive impact on the performance of the firms under the investigation. In view of the above finding, this study makes the following recommendations for the policymakers in Nigeria that anytime the goal of the policymakers is the improvement of performance of the listed firms in the Nigerian stock exchange, board independence and a balance in the inclusion of male and female among the board of directors should be encouraged in these firms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=corporate" title="corporate">corporate</a>, <a href="https://publications.waset.org/abstracts/search?q=governance" title=" governance"> governance</a>, <a href="https://publications.waset.org/abstracts/search?q=firms" title=" firms"> firms</a>, <a href="https://publications.waset.org/abstracts/search?q=performance" title=" performance"> performance</a>, <a href="https://publications.waset.org/abstracts/search?q=Nigeria" title=" Nigeria"> Nigeria</a>, <a href="https://publications.waset.org/abstracts/search?q=stock" title=" stock"> stock</a>, <a href="https://publications.waset.org/abstracts/search?q=exchange" title=" exchange"> exchange</a> </p> <a href="https://publications.waset.org/abstracts/145199/corporate-governance-and-firms-performance-evidence-from-quoted-firms-on-the-nigerian-stock-exchange" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/145199.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">175</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">60</span> The Cost of Solar-Centric Renewable Portfolio </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Timothy%20J.%20Considine">Timothy J.

The framework is used to quantify the impact of state-level renewable portfolio standards (RPSs) achieved predominately with solar generation on electricity rates, electricity consumption, and environmental quality. We perform the analysis using Arizona’s RPS as a case study. We forecast energy demand in Arizona out to 2035, and find by this time the state will require an additional 35 million MWh of electricity generation. If Arizona implements its RPS when supplying this electricity demand, we find there will be a substantial increase in electricity rates (relative to a business-as-usual scenario of reliance on gas-fired generation). Extending the current regime of tax credits can greatly reduce this increase, at the taxpayers’ expense. We find that by 2025 Arizona’s RPS will implicitly abate carbon dioxide emissions at a cost between $101 and $135 per metric ton, and by 2035 abatement costs are between $64 and $112 per metric ton (depending on the future evolution of nature gas prices). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electricity%20demand" title="electricity demand">electricity demand</a>, <a href="https://publications.waset.org/abstracts/search?q=renewable%20portfolio%20standard" title=" renewable portfolio standard"> renewable portfolio standard</a>, <a href="https://publications.waset.org/abstracts/search?q=solar" title=" solar"> solar</a>, <a href="https://publications.waset.org/abstracts/search?q=carbon%20dioxide" title=" carbon dioxide"> carbon dioxide</a> </p> <a href="https://publications.waset.org/abstracts/25663/the-cost-of-solar-centric-renewable-portfolio" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25663.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">485</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">59</span> Evaluating the Factors Influencing the Efficiency and Usage of Public Sports Services in a Chinese Province</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zhankun%20Wang">Zhankun Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Timothy%20Makubuya"> Timothy Makubuya</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The efficiency of public sports service of prefecture-level cities in Zhejiang from 2008 to 2012 was evaluated by applying the DEA method, then its influencing factors were also analyzed through Tobit model. Upon analysis, the results revealed the following; (i) the change in average efficiency of public sports service in Zhejiang present a smooth uptrend and at a relatively high level from 2008 to 2012 (ii) generally, the productivity of public sports service in Zhejiang improved from 2008 to 2012, the productivity efficiency varied greatly in different years, and the regional difference of production efficiency increased. (iii) The correlations for urbanization rate, aging rate, per capita GDP and the population density were significantly positive with the public sports service efficiency in Zhejiang, of which the most significant was the aging rate. However, the population density and per capita GDP had less impact on the efficiency of public sports service in Zhejiang. In addition, whether the efficiency of public sports services in different areas in Zhejiang reciprocates to overall benefits in public wellbeing in both rural and urban settings is still arguable. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DEA%20model" title="DEA model">DEA model</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20sports%20service" title=" public sports service"> public sports service</a>, <a href="https://publications.waset.org/abstracts/search?q=efficiency" title=" efficiency"> efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=Tobit%20model" title=" Tobit model"> Tobit model</a>, <a href="https://publications.waset.org/abstracts/search?q=Malmquist%20productivity%20index" title=" Malmquist productivity index"> Malmquist productivity index</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhejiang" title=" Zhejiang"> Zhejiang</a> </p> <a href="https://publications.waset.org/abstracts/91097/evaluating-the-factors-influencing-the-efficiency-and-usage-of-public-sports-services-in-a-chinese-province" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/91097.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">289</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">58</span> Accidental Compartment Fire Dynamics: Experiment, Computational Fluid Dynamics Weakness and Expert Interview Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Timothy%20Onyenobi">Timothy Onyenobi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Accidental fires and its dynamic as it relates to building compartmentation and the impact of the compartment morphology, is still an on-going area of study; especially with the use of computational fluid dynamics (CFD) modeling methods. With better knowledge on this subject come better solution recommendations by fire engineers. Interviews were carried out for this study where it was identified that the response perspectives to accidental fire were different with the fire engineer providing qualitative data which is based on “what is expected in real fires” and the fire fighters provided information on “what actually obtains in real fires”. This further led to a study and analysis of two real and comprehensively instrumented fire experiments: the Open Plan Office Project by National Institute of Standard and Technology (NIST) USA (to study time to flashover) and the TF2000 project by the Building Research Establishment (BRE) UK (to test for conformity with Building Regulation requirements). The findings from the analysis of the experiments revealed the relative yet critical weakness of fire prediction using a CFD model (usually used by fire engineers) as well as explained the differences in response perspectives of the fire engineers and firefighters from the interview analysis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CFD" title="CFD">CFD</a>, <a href="https://publications.waset.org/abstracts/search?q=compartment%20fire" title=" compartment fire"> compartment fire</a>, <a href="https://publications.waset.org/abstracts/search?q=experiment" title=" experiment"> experiment</a>, <a href="https://publications.waset.org/abstracts/search?q=fire%20fighters" title=" fire fighters"> fire fighters</a>, <a href="https://publications.waset.org/abstracts/search?q=fire%20engineers" title=" fire engineers"> fire engineers</a> </p> <a href="https://publications.waset.org/abstracts/61009/accidental-compartment-fire-dynamics-experiment-computational-fluid-dynamics-weakness-and-expert-interview-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61009.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">337</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">57</span> Physically Informed Kernels for Wave Loading Prediction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Daniel%20James%20Pitchforth">Daniel James Pitchforth</a>, <a href="https://publications.waset.org/abstracts/search?q=Timothy%20James%20Rogers"> Timothy James Rogers</a>, <a href="https://publications.waset.org/abstracts/search?q=Ulf%20Tyge%20Tygesen"> Ulf Tyge Tygesen</a>, <a href="https://publications.waset.org/abstracts/search?q=Elizabeth%20Jane%20Cross"> Elizabeth Jane Cross</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Wave loading is a primary cause of fatigue within offshore structures and its quantification presents a challenging and important subtask within the SHM framework. The accurate representation of physics in such environments is difficult, however, driving the development of data-driven techniques in recent years. Within many industrial applications, empirical laws remain the preferred method of wave loading prediction due to their low computational cost and ease of implementation. This paper aims to develop an approach that combines data-driven Gaussian process models with physical empirical solutions for wave loading, including Morison’s Equation. The aim here is to incorporate physics directly into the covariance function (kernel) of the Gaussian process, enforcing derived behaviors whilst still allowing enough flexibility to account for phenomena such as vortex shedding, which may not be represented within the empirical laws. The combined approach has a number of advantages, including improved performance over either component used independently and interpretable hyperparameters. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=offshore%20structures" title="offshore structures">offshore structures</a>, <a href="https://publications.waset.org/abstracts/search?q=Gaussian%20processes" title=" Gaussian processes"> Gaussian processes</a>, <a href="https://publications.waset.org/abstracts/search?q=Physics%20informed%20machine%20learning" title=" Physics informed machine learning"> Physics informed machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=Kernel%20design" title=" Kernel design"> Kernel design</a> </p> <a href="https://publications.waset.org/abstracts/146250/physically-informed-kernels-for-wave-loading-prediction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146250.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">192</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">56</span> The Effect of Voice Recognition Dictation Software on Writing Quality in Third Grade Students: An Action Research Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Timothy%20J.%20Grebec">Timothy J.

The research took place in a third-grade general education classroom in a suburban school setting. Because the study involved minors, all data was encrypted and deidentified before analysis. The students completed a series of writings prior to the beginning of the intervention to determine their thoughts and skill level with writing. During the intervention phase, the students were introduced to the voice dictation software, given an opportunity to practice using it, and then assigned writing prompts to be completed using the software. The prompts written by nineteen student participants and surveys of student opinions on writing established a baseline for the study. The data showed that using the dictation software resulted in a 34% increase in the response quality (compared to the Pennsylvania State Standardized Assessment [PSSA] writing guidelines). Of particular interest was the increase in students' proficiency in demonstrating mastery of the English language and conventions and elaborating on the content. Although this type of research is relatively no, it has the potential to reshape the strategies educators have at their disposal when instructing students on written language. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=educational%20technology" title="educational technology">educational technology</a>, <a href="https://publications.waset.org/abstracts/search?q=accommodations" title=" accommodations"> accommodations</a>, <a href="https://publications.waset.org/abstracts/search?q=students%20with%20disabilities" title=" students with disabilities"> students with disabilities</a>, <a href="https://publications.waset.org/abstracts/search?q=writing%20instruction" title=" writing instruction"> writing instruction</a>, <a href="https://publications.waset.org/abstracts/search?q=21st%20century%20education" title=" 21st century education"> 21st century education</a> </p> <a href="https://publications.waset.org/abstracts/170286/the-effect-of-voice-recognition-dictation-software-on-writing-quality-in-third-grade-students-an-action-research-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/170286.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">75</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">55</span> Examining the Influence of Question Phrasing in Police Interviews on Suspects’ Inferences Regarding Interviewer’s Prior Knowledge</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Meghana%20Srivatsav">Meghana Srivatsav</a>, <a href="https://publications.waset.org/abstracts/search?q=Timothy%20J.%20Luke"> Timothy J.

Three phrasing factors were explored namely specificity (crime-related details within questions), stressor (emphasis on the importance of the information in the question) and phase presentation (whether a specific activity was questioned about). 370 participants were recruited and randomly assigned into 6 different question-phrasing groups. Participants assumed the role of a suspect, read a crime narrative and an interview transcript based on the suspect’s activities. Participants responded to scales that measured their perception of interviewer’s knowledge (PIK) based on the questions posed by the interviewer in the interview transcripts. The researchers found that there is an effect of specific details revealed in the questions on the suspect’s perception of interviewer knowledge. Questioning about a specific activity also increased their perception of interviewer’s prior knowledge. However, the individual hypotheses were only partially supported. The study allowed the researchers to explore a psycholinguistic approach to investigate the underlying mechanisms of inferences drawn by suspects from the phrasing of investigative questions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=police%20interviewing" title="police interviewing">police interviewing</a>, <a href="https://publications.waset.org/abstracts/search?q=question%20framing%20effects%20on%20suspects" title=" question framing effects on suspects"> question framing effects on suspects</a>, <a href="https://publications.waset.org/abstracts/search?q=suspect%20inferences%20from%20questions" title=" suspect inferences from questions"> suspect inferences from questions</a>, <a href="https://publications.waset.org/abstracts/search?q=suspect%20interviews" title=" suspect interviews"> suspect interviews</a> </p> <a href="https://publications.waset.org/abstracts/101778/examining-the-influence-of-question-phrasing-in-police-interviews-on-suspects-inferences-regarding-interviewers-prior-knowledge" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/101778.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">54</span> Sustainable Development of Medium Strength Concrete Using Polypropylene as Aggregate Replacement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Reza%20Keihani">Reza Keihani</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Bahadori-Jahromi"> Ali Bahadori-Jahromi</a>, <a href="https://publications.waset.org/abstracts/search?q=Timothy%20James%20Clacy"> Timothy James Clacy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Plastic as an environmental burden is a well-rehearsed topic in the research area. This is due to its global demand and destructive impacts on the environment, which has been a significant concern to the governments. Typically, the use of plastic in the construction industry is seen across low-density, non-structural applications due to its diverse range of benefits including high strength-to-weight ratios, manipulability and durability. It can be said that with the level of plastic consumption experienced in the construction industry, an ongoing responsibility is shown for this sector to continually innovate alternatives for application of recycled plastic waste such as using plastic made replacement from polyethylene, polystyrene, polyvinyl and polypropylene in the concrete mix design. In this study, the impact of partially replaced fine aggregate with polypropylene in the concrete mix design was investigated to evaluate the concrete’s compressive strength by conducting an experimental work which comprises of six concrete mix batches with polypropylene replacements ranging from 0.5 to 3.0%. The results demonstrated a typical decline in the compressive strength with the addition of plastic aggregate, despite this reduction generally mitigated as the level of plastic in the concrete mix increased. Furthermore, two of the six plastic-containing concrete mixes tested in the current study exceeded the ST5 standardised prescribed concrete mix compressive strength requirement at 28-days containing 1.50% and 2.50% plastic aggregates, which demonstrated the potential for use of recycled polypropylene in structural applications, as a partial by mass, fine aggregate replacement in the concrete mix. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=compressive%20strength" title="compressive strength">compressive strength</a>, <a href="https://publications.waset.org/abstracts/search?q=concrete" title=" concrete"> concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=polypropylene" title=" polypropylene"> polypropylene</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a> </p> <a href="https://publications.waset.org/abstracts/108936/sustainable-development-of-medium-strength-concrete-using-polypropylene-as-aggregate-replacement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108936.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">140</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">53</span> Agriculture, Food Security and Poverty Reduction in Nigeria: Cointegration and Granger Causality Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ogunwole%20Cecilia%20Oluwakemi">Ogunwole Cecilia Oluwakemi</a>, <a href="https://publications.waset.org/abstracts/search?q=Timothy%20Ayomitunde%20Aderemi"> Timothy Ayomitunde Aderemi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Provision of sufficient food and elimination of abject poverty have usually been the conventional benefits of agriculture in any society. Meanwhile, despite the fact that Nigeria is an agrarian society, food insecurity and poverty have become the issues of concern among both scholars and policymakers in the recent times. Against this backdrop, this study examined the nexus among agriculture, food security, and poverty reduction in Nigeria from 1990 to 2019 within the framework of the Cointegration and Granger Causality approach. Data was collected from the Central Bank of Nigeria Statistical Bulletin and the World Development Indicators, respectively. The following are the major results that emanated from the study. A long run equilibrium relationship exists among agricultural value added, food production index, and GDP per capita in Nigeria. Similarly, there is a unidirectional causality which flows from food production index to poverty reduction in Nigeria. In the same vein, one way causality flows from poverty reduction to agricultural value added in Nigeria. Consequently, this study makes the following recommendation for the policymakers in Nigeria, and other African countries by extension, that agricultural value added and food production are the important variables that cannot be undermined when poverty reduction occupies the central focus of the policymakers. Therefore, any time these policymakers want to reduce poverty, policies that drive agricultural value added and food production should be embarked upon. Therefore, this study will contribute to the literature by establishing the type of linkage that exists between agriculture, food security, and poverty reduction in Nigeria. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agriculture" title="agriculture">agriculture</a>, <a href="https://publications.waset.org/abstracts/search?q=value%20added" title=" value added"> value added</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20production" title=" food production"> food production</a>, <a href="https://publications.waset.org/abstracts/search?q=GDP%20per%20capita" title=" GDP per capita"> GDP per capita</a>, <a href="https://publications.waset.org/abstracts/search?q=Nigeria" title=" Nigeria"> Nigeria</a> </p> <a href="https://publications.waset.org/abstracts/146377/agriculture-food-security-and-poverty-reduction-in-nigeria-cointegration-and-granger-causality-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146377.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">194</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">52</span> A Review of Food Reformulation of Sweetened Baked Goods to Reduce Added Sugar Intake</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Xiao%20Luo">Xiao Luo</a>, <a href="https://publications.waset.org/abstracts/search?q=Jayashree%20Arcot"> Jayashree Arcot</a>, <a href="https://publications.waset.org/abstracts/search?q=Timothy%20P.%20Gill"> Timothy P.

Rangan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Excessive consumption of added sugar is negatively associated with many health outcomes such as lower diet quality, dental diseases and other non-communicable diseases. Sugar-sweetened baked goods are popular discretionary foods that contribute significant amounts of added sugar to people’s diets worldwide. Food reformulation is of the most effective methods to reduce consumption of added sugar without significantly altering individual's diet pattern. However, sucrose, as the major sugar in baked goods, plays several vital functional roles such as providing sweetness and bulking, and suitable substitutes must be able to address these. The review examines the literature on sugar-reduced baked goods to summarise the feasible reformulations of low/no added sugar baked goods, and indicates the future directions for healthier baked goods reformulation. Based on this review, polyols and non-nutritive sweeteners (NNS) are suitable for alternative sweeteners to partially or fully replace sucrose in baked goods. Low-calorie carbohydrates such as oligofructose, polydextrose, maltodextrins are the mostly used bulking agents to compensate the loss of bulk due to the removal of sucrose. This review found that maltitol seems the most suitable sole sucrose substitution at present, while diverse mixtures of NNS( stevia, sucralose, acesulfame-K), other polyols and inulins can also deliver the functionalities of sucrose in baked products. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alternative%20sweeteners" title="alternative sweeteners">alternative sweeteners</a>, <a href="https://publications.waset.org/abstracts/search?q=baked%20goods" title=" baked goods"> baked goods</a>, <a href="https://publications.waset.org/abstracts/search?q=reformulation" title=" reformulation"> reformulation</a>, <a href="https://publications.waset.org/abstracts/search?q=sugar%20reduction" title=" sugar reduction"> sugar reduction</a> </p> <a href="https://publications.waset.org/abstracts/92990/a-review-of-food-reformulation-of-sweetened-baked-goods-to-reduce-added-sugar-intake" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92990.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">51</span> Bayesian Inference for High Dimensional Dynamic Spatio-Temporal Models</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sofia%20M.%20Karadimitriou">Sofia M.

A basic state space model is adopted for the discrete temporal variation, while a continuous autoregressive structure describes the continuous spatial evolution. Application of such a DSTM relies upon the pre-selection of a suitable reduced set of basic functions and this can present a challenge in practice. In this talk, we propose an online estimation method for high dimensional spatio-temporal data based upon DSTM and we attempt to resolve this issue by allowing the basis to adapt to the observed data. Specifically, we present a wavelet decomposition in order to obtain a parsimonious approximation of the spatial continuous process. This parsimony can be achieved by placing a Laplace prior distribution on the wavelet coefficients. The aim of using the Laplace prior, is to filter wavelet coefficients with low contribution, and thus achieve the dimension reduction with significant computation savings. We then propose a Hierarchical Bayesian State Space model, for the estimation of which we offer an appropriate particle filter algorithm. The proposed methodology is illustrated using real environmental data. <p class="card-text"><strong>Keywords:</strong> <a
