class="card-text"><strong>Abstract:</strong></p> Sheep flystrike is one of the most economically important diseases affecting the Australian sheep and wool industry (>356M/annually). Currently, control of Lucillia cuprina relies almost exclusively on chemicals controls and the parasite has developed resistance to nearly all control chemicals used in the past. It is therefore critical to develop an alternative solution for the sustainable control and management of flystrike. RNA interference (RNAi) technologies have been successfully explored in multiple animal industries for developing parasites controls. This research project aims to develop a RNAi based biological control for sheep blowfly. Double-stranded RNA (dsRNA) has already proven successful against viruses, fungi and insects. However, the environmental instability of dsRNA is a major bottleneck with a protection window only lasting 5-7 days. Bentonite polymer (BenPol) technology can overcome this problem, as it can be tuned for controlled release of the dsRNA in the gut challenging pH environment of the blowfly larvae, prolonging its exposure time to and uptake by target cells. We have investigated four different BenPol carriers for their dsRNA loading capabilities of which three of them were able to afford dsRNA stability under multiple temperatures (4°C, 22°C, 40°C, 55°C) in the sheep serum. Based on stability results, we further tested dsRNA from potential targeted genes loaded with BenPol carrier in larvae feeding assay, and get three knockdowns. Our results, establish that the dsRNA when loaded on BenPol particles is stable unlike naked dsRNA which is rapidly degraded in the sheep serum. A stable nanoparticles delivery system that can protect and increase the inherent stability of the dsRNA molecules at higher temperatures in a complex biological fluid like serum, offers a great deal of promise for the future use of this approach for enhancing animal protection. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=RNA%20interference" title="RNA interference">RNA interference</a>, <a href="https://publications.waset.org/abstracts/search?q=Lucillia%20cuprina" title=" Lucillia cuprina"> Lucillia cuprina</a>, <a href="https://publications.waset.org/abstracts/search?q=polymer%20carriers" title=" polymer carriers"> polymer carriers</a>, <a href="https://publications.waset.org/abstracts/search?q=polymer%20stability" title=" polymer stability"> polymer stability</a> </p> <a href="https://publications.waset.org/abstracts/163869/enhancing-animal-protection-topical-rnai-with-polymer-carriers-for-sustainable-animal-health-in-australian-sheep-flystrike" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163869.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">81</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> Development of a Stable RNAi-Based Biological Control for Sheep Blowfly Using Bentonite Polymer Technology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yunjia%20Yang">Yunjia Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Peng%20Li"> Peng Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Gordon%20Xu"> Gordon Xu</a>, <a href="https://publications.waset.org/abstracts/search?q=Timothy%20Mahony"> Timothy Mahony</a>, <a href="https://publications.waset.org/abstracts/search?q=Bing%20Zhang"> Bing Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Neena%20Mitter"> Neena Mitter</a>, <a href="https://publications.waset.org/abstracts/search?q=Karishma%20Mody"> Karishma Mody</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Sheep flystrike is one of the most economically important diseases affecting the Australian sheep and wool industry (>356M/annually).

This research can be described as an exploratory effort to better understand how, and perhaps why, gangs employ this medium for communication.

There exists a relationship between the meteorological data and milk yield prediction accuracy in pasture-based dairy systems. New precision technologies are available and are being developed to improve the sustainability of the dairy industry. Some of these technologies focus on welfare of individual animals on dairy farms. These technologies allow the automatic identification of animal behaviour and health events, greatly increasing overall herd health and yield while reducing animal health inspection demands and long-term animal healthcare costs. The data set consisted of records from 489 dairy cows at two dairy farms and temperature measured from the nearest meteorological weather station in 2018. The effects of temperature on milk production and behaviour of animals were analyzed. The statistical results indicate different effects of temperature on milk yield and behaviour. The “comfort zone” for animals is in the range 10 °C to 20 °C. Dairy cows out of this zone had to decrease or increase their metabolic heat production, and it affected their milk production and behaviour. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=behavior" title="behavior">behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=milk%20yield" title=" milk yield"> milk yield</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature" title=" temperature"> temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=precision%20technologies" title=" precision technologies"> precision technologies</a> </p> <a href="https://publications.waset.org/abstracts/125573/influence-of-environmental-temperature-on-dairy-herd-performance-and-behaviour" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/125573.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">109</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">74</span> 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.

The aim of this study is to examine the association of COVID-19 safety training and communication with stress. Methods: A 91-item online survey was distributed, starting January 2, 2021, to non-physician healthcare workers, including physician assistants, nurse practitioners, and medical assistants (MAs) in the United States through email and social media. A $1 donation was made to the Red Cross for each completed survey. The survey consisted of demographics, occupational questions, and perceived stress (perceived stress scale, PSS). Items on the PSS were combined for an overall score and categorized according to the severity of perceived stress. Chi-square tests were performed for bivariate analyses of categorical variables. Results: Of the 284 participants consenting to complete the survey, 197 participants completed the full survey. MAs made up most of the sample at 79%. Among all respondents, 47% had moderate PSS scores (scored between 14 and 26), and 51% had severe PSS scores (scored between 27 and 40). Unvaccinated participants reported statistically significantly lower levels of perceived stress (p = 0.002). Performing tasks outside of typical job responsibilities was not associated with PSS scores (p = .667). Discussion: Non-physician healthcare workers demonstrated a high level of perceived stress overall. The association between vaccination status and perceived stress should be examined in order to evaluate whether vaccination levels could be improved with further education about the virus and associated risks. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=COVID-19" title="COVID-19">COVID-19</a>, <a href="https://publications.waset.org/abstracts/search?q=SARS-Cov-2" title=" SARS-Cov-2"> SARS-Cov-2</a>, <a href="https://publications.waset.org/abstracts/search?q=nursing" title=" nursing"> nursing</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20health" title=" public health"> public health</a> </p> <a href="https://publications.waset.org/abstracts/141302/non-physician-medical-worker-experience-during-the-covid-19-pandemic" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141302.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">72</span> A Student Centered Learning Environment in Engineering Education: Design and a Longitudinal Study of Impact</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tom%20O%27Mahony">Tom O'Mahony</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This article considers the design of a student-centered learning environment in engineering education. The learning environment integrates a number of components, including project-based learning, collaborative learning, two-stage assignments, active learning lectures, and a flipped-classroom. Together these elements place the individual learner and their learning at the center of the environment by focusing on understanding, enhancing relevance, applying learning, obtaining rich feedback, making choices, and taking responsibility. The evolution of this environment from 2014 to the present day is outlined. The impact of this environment on learners and their learning is evaluated via student questionnaires that consist of both open and closed-ended questions. The closed questions indicate that students found the learning environment to be really interesting and enjoyable (rated as 4.7 on a 5 point scale) and encouraged students to adopt a deep approach towards studying the course materials (rated as 4.0 on a 5 point scale). A content analysis of the open-ended questions provides evidence that the project, active learning lectures, and flipped classroom all contribute to the success of this environment. Furthermore, this analysis indicates that the two-stage assessment process, in which feedback is provided between a draft and final assignment, is the key component and the dominant theme. A limitation of the study is the small class size (less than 20 learners per year), but, to some degree, this is compensated for by the longitudinal nature of the study. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=deep%20approaches" title="deep approaches">deep approaches</a>, <a href="https://publications.waset.org/abstracts/search?q=formative%20assessment" title=" formative assessment"> formative assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=project-based%20learning" title=" project-based learning"> project-based learning</a>, <a href="https://publications.waset.org/abstracts/search?q=student-centered%20learning" title=" student-centered learning"> student-centered learning</a> </p> <a href="https://publications.waset.org/abstracts/127997/a-student-centered-learning-environment-in-engineering-education-design-and-a-longitudinal-study-of-impact" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/127997.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">71</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">70</span> Decision-Making Strategies on Smart Dairy Farms: A Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=L.%20Krpalkova">L.

Dairy farms have embraced technological innovations and procured vast amounts of permanent data streams during the past decade; however, the integration of this information to improve the whole farm-based management and decision-making does not exist. It is now imperative to develop a system that can collect, integrate, manage, and analyse on-farm and off-farm data in real-time for practical and relevant environmental and economic actions. The developed systems, based on machine learning and artificial intelligence, need to be connected for useful output, a better understanding of the whole farming issue, and environmental impact. Evolutionary computing can be very effective in finding the optimal combination of sets of some objects and, finally, in strategy determination. The system of the future should be able to manage the dairy farm as well as an experienced dairy farm manager with a team of the best agricultural advisors. All these changes should bring resilience and sustainability to dairy farming as well as improving and maintaining good animal welfare and the quality of dairy products. This review aims to provide an insight into the state-of-the-art of big data applications and evolutionary computing in relation to smart dairy farming and identify the most important research and development challenges to be addressed in the future. Smart dairy farming influences every area of management, and its uptake has become a continuing trend. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=big%20data" title="big data">big data</a>, <a href="https://publications.waset.org/abstracts/search?q=evolutionary%20computing" title=" evolutionary computing"> evolutionary computing</a>, <a href="https://publications.waset.org/abstracts/search?q=cloud" title=" cloud"> cloud</a>, <a href="https://publications.waset.org/abstracts/search?q=precision%20technologies" title=" precision technologies"> precision technologies</a> </p> <a href="https://publications.waset.org/abstracts/130338/decision-making-strategies-on-smart-dairy-farms-a-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130338.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">189</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">69</span> The Impact of the New Head Injury Pathway on the Number of CTs Performed in a Paediatric Population</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amel%20M.%20A.%20Osman">Amel M.

A new head injury (HI) pathway was introduced in 2021, which altered the previous process of HI being jointly admitted with general pediatrics and surgery to admit these patients under the Emergency Medicine Team. Admitted patients included those with positive CT findings not requiring immediate neurosurgical intervention and those who did not meet current criteria for urgent CT brain as per NICE guidelines but were still symptomatic for prolonged observations. This approach aims to decrease the number of CT scans performed. The main aim is to assess the variation in CT scanning rates since the change in the admitting process. A retrospective review of patients presenting to CHI PECU with HI over 6-month period (01/01/19-31/05/19) compared to a 6-month period post introduction of the new pathway (01/06/2022-31/12/2022). Data was collected from the electronic record databases, symphony, and PACS. Results: In 2019, there were 869 presentations of HI, among which 32 (3.68%) had CT scans performed. 2 (6.25%) of those scanned had positive findings. In 2022, there were 1122 HI presentations, with 47 (4.19%) CT scans performed and positive findings in 5 (10.6%) cases. 57 patients were admitted under the new pathway for observation, with 1 having a CT scan following admission. Conclusion: Quantitative lifetime radiation risks for children are not negligible. While there was no statistically significant reduction in CTs performed amongst HIs presenting to our department, a significant group met the criteria for admission under the PECU consultant for prolonged monitoring. There was also a greater proportion of abnormalities on CT scans performed in 2022, demonstrating improved patient selection for imaging. Further data analysis is ongoing to determine if those who were admitted would have previously been scanned under the old pathway. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=head%20injury" title="head injury">head injury</a>, <a href="https://publications.waset.org/abstracts/search?q=CT" title=" CT"> CT</a>, <a href="https://publications.waset.org/abstracts/search?q=admission" title=" admission"> admission</a>, <a href="https://publications.waset.org/abstracts/search?q=guidline" title=" guidline"> guidline</a> </p> <a href="https://publications.waset.org/abstracts/184415/the-impact-of-the-new-head-injury-pathway-on-the-number-of-cts-performed-in-a-paediatric-population" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/184415.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">53</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">68</span> Hand Hygiene Habits of Ghanaian Youths in Accra</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cecilia%20Amponsem-Boateng">Cecilia Amponsem-Boateng</a>, <a href="https://publications.waset.org/abstracts/search?q=Timothy%20B.%20Oppong"> Timothy B.

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">67</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">66</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.

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.

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">62</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. Turbo generators are one of the primary and critical components in energy generation. It is essential to apply correct maintenance strategies and apply operational procedures accordingly. The maintenance strategies are implemented to ensure the high reliability of the equipment. The study was carried out at a coal power station which will transit to a cleaner energy source in the nearest future. The study is relevant as lessons learned in this system will support plans and operational models implemented when cleaner energy sources replace coal-powered turbines. This paper first outlines different maintenance strategies executed on the turbo-generator modules.

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">59</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">176</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> 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">56</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">55</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">54</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">53</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">52</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">51</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">50</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
