Teachers’ cluster meeting intervention is a step towards enhancing the teachers’ professional competency, efficient and effective pupils’ academic achievement and attitudinal development. The study thus determined the impact of the intervention on pupils’ achievement in Oyo State, Nigeria. Three research questions and four hypotheses guided the study. Pre-test, post-test control group, quasi-experimental design was adopted for the study. Eight intact classes from eight different schools were randomly selected into treatment and control groups. Two response instruments, pupils academic achievement test (PAAT; r = 0.87) and pupils attitude to lesson scale (PALS; r = 0.80) were used for data collection. Mean, standard deviation and analysis of covariance (ANCOVA) were used to analyse the collected data. The results showed that the teachers’ cluster meeting have significant impact on pupils academic achievement (F (1,327) =41.79; p<0.05) and attitudinal development (F (1,327) =26.01; p<0.05) in the core subjects of primary schools in Oyo State, Nigeria. The study therefore recommended among others that teachers’ cluster meeting should be sustained for teachers’ professional development and pupils’ upgradement in the State. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=teachers%E2%80%99%20cluster%20meeting" title="teachers’ cluster meeting">teachers’ cluster meeting</a>, <a href="https://publications.waset.org/abstracts/search?q=pupils%E2%80%99%20academic%20achievement" title=" pupils’ academic achievement"> pupils’ academic achievement</a>, <a href="https://publications.waset.org/abstracts/search?q=pupils%E2%80%99%20attitudinal%20development" title=" pupils’ attitudinal development"> pupils’ attitudinal development</a>, <a href="https://publications.waset.org/abstracts/search?q=academic%20achievement" title=" academic achievement "> academic achievement </a> </p> <a href="https://publications.waset.org/abstracts/8798/impacts-of-teachers-cluster-model-meeting-intervention-on-pupils-learning-academic-achievement-and-attitudinal-development-in-oyo-state-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8798.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">471</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">378</span> Class-Size and Instructional Materials as Correlates of Pupils Learning and Academic Achievement in Primary School</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aanuoluwapo%20Olusola%20Adesanya">Aanuoluwapo Olusola Adesanya</a>, <a href="https://publications.waset.org/abstracts/search?q=Adesina%20Joseph"> Adesina Joseph </a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper examined the class-size and instructional materials as correlates of pupils learning and academic achievement in primary school. The population of the study comprised 198 primary school pupils in three selected schools in Ogun State, Nigeria. Data were collected through questionnaire and were analysed with the use of multiple regression and ANOVA to analysed the correlation between class-size, instructional materials (independent variables) and learning achievement (dependent variable). The findings revealed that schools having an average class-size of 30 and below with use of instructional materials obtained better results than schools having more than 30 and above. The main score were higher in the school in schools having 30 and below than schools with 30 and above. It was therefore recommended that government, stakeholders and NGOs should provide more classrooms and supply of adequate instructional materials in all primary schools in the state to cater for small class-size. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=class-size" title="class-size">class-size</a>, <a href="https://publications.waset.org/abstracts/search?q=instructional%20materials" title=" instructional materials"> instructional materials</a>, <a href="https://publications.waset.org/abstracts/search?q=learning" title=" learning"> learning</a>, <a href="https://publications.waset.org/abstracts/search?q=academic%20achievement" title=" academic achievement "> academic achievement </a> </p> <a href="https://publications.waset.org/abstracts/10419/class-size-and-instructional-materials-as-correlates-of-pupils-learning-and-academic-achievement-in-primary-school" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10419.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">350</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">377</span> Predicting the Effects of Counseling Psychology on the Sexual Risk Behavior of In-School Adolescents: Implication for National Development</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Olusola%20Joseph%20Adesina">Olusola Joseph Adesina</a>, <a href="https://publications.waset.org/abstracts/search?q=Adebayo%20Adeyinka%20Salako"> Adebayo Adeyinka Salako</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study adopted a descriptive research design. Two hundred (200) in-school adolescents were purposely selected in Afijio Local Government Area of Oyo State. Two hypotheses were also raised to pilot the study. The researchers developed an instrument which was validated by psychological experts, the instrument tagged counseling psychology and sexual risk behavior questionnaire (CPSRBQ)(r = 0.78). The results were analysed using t-test at 0.05 level of significance. The result showed that there is a significant relationship between counseling psychology and sexual risk behavior of in-school adolescents. It was also noticed that there is a significant difference in the sexual risk behavior of male and female adolescents. Based on the findings, it was recommended that more counselors are still needed in Nigeria schools. There is need for restructuring Nigeria Curriculum most especially on sex education and related diseases. Lastly, adolescents should be more exposed to seminars on HIV/AIDS, sex education enlightenment programmes and marital counseling. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=counseling%20psychology" title="counseling psychology">counseling psychology</a>, <a href="https://publications.waset.org/abstracts/search?q=sexual%20behavior" title=" sexual behavior"> sexual behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20and%20adolescent" title=" risk and adolescent"> risk and adolescent</a>, <a href="https://publications.waset.org/abstracts/search?q=cognitive%20sciences" title=" cognitive sciences"> cognitive sciences</a> </p> <a href="https://publications.waset.org/abstracts/6773/predicting-the-effects-of-counseling-psychology-on-the-sexual-risk-behavior-of-in-school-adolescents-implication-for-national-development" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6773.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">508</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">376</span> Efficacy of Teachers' Cluster Meetings on Teachers' Lesson Note Preparation and Teaching Performance in Oyo State, Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Olusola%20Joseph%20Adesina">Olusola Joseph Adesina</a>, <a href="https://publications.waset.org/abstracts/search?q=Sunmaila%20Oyetunji%20Raimi"> Sunmaila Oyetunji Raimi</a>, <a href="https://publications.waset.org/abstracts/search?q=Olufemi%20Akinloye%20Bolaji"> Olufemi Akinloye Bolaji</a>, <a href="https://publications.waset.org/abstracts/search?q=Abiodun%20Ezekiel%20Adesina"> Abiodun Ezekiel Adesina</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The quality of education and the standard of a nation cannot rise above the quality of the teacher (NPE, 2004). Efforts at improving the falling standard of education in the country call for the need-based assessment of the primary tier of education in Nigeria. It was revealed that the teachers’ standard of performance and pupils’ achievement was below average. Teachers’ cluster meeting intervention was therefore recommended as a step towards enhancing the teachers’ professional competency, efficient and effective proactive and interactive lesson presentation. The study thus determined the impact of the intervention on teachers’ professional performance (lesson note preparation and teaching performance) in Oyo State, Nigeria. The main and interaction effects of the gender of the teachers as moderator variable were also determined. Three null hypotheses guided the study. Pre-test, posttest control group quazi experimental design was adopted for the study. Three hundred intact classes from three hundred different schools were randomly selected into treatment and control groups.

Multi-stage sampling technique was adopted for sampling the respondents. Data used for the study were obtained from primary source. Structured questionnaire with interview schedule was administered to 180 randomly selected rural farmers in the study area. Descriptive statistics analysis and z-test statistics were used to analyse the data collected. The study revealed the mean age of the household to be 43 years, mean years of schooling was 8.5, mean household size was 6 people, mean farming experience of 17.5 years and mean farm size of 1.8 hectares. The effect of livelihood diversification revealed that livelihood diversification had positive and significant effect on food security (65.6%) and income generation (66.8%) in the study area. The major constraints to diversification in the study area were poor infrastructure, unavailability of credit and climatic risk and uncertainty. The study, therefore, recommended that rural household should be sensitised to diversify their income source into non-farm activities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=income" title="income">income</a>, <a href="https://publications.waset.org/abstracts/search?q=livelihood%20diversification" title=" livelihood diversification "> livelihood diversification </a>, <a href="https://publications.waset.org/abstracts/search?q=rural%20household" title=" rural household"> rural household</a>, <a href="https://publications.waset.org/abstracts/search?q=welfare" title=" welfare"> welfare</a> </p> <a href="https://publications.waset.org/abstracts/56111/perceived-effect-of-livelihood-diversification-on-the-welfare-of-rural-households-in-niger-state-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56111.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">415</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">373</span> Influence of Alcohol Consumption on Attention in Wistar Albino Rats</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adekunle%20Adesina">Adekunle Adesina</a>, <a href="https://publications.waset.org/abstracts/search?q=Dorcas%20Adesina"> Dorcas Adesina</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This Research investigated the influence of alcohol consumption on attention in Wister albino rats. It was designed to test whether or not alcohol consumption affected visual and auditory attention. The sample of this study comprise of 3males albino rats and 3 females albino rats which were randomly assigned to 3 (male/female each) groups, 1, 2 and 3. The first group which was experimental Group 1 received 4ml of alcohol ingestion with cannula twice daily (morning and evening). The second group which was experimental group 2 received 2ml of alcohol ingestion with cannula twice daily (morning and evening). Third group which was the control group only received water (placebo), all these happened within a period of 2 days. Three hypotheses were advanced and testedf in the study. Hypothesis 1 stated that there will be no significant difference between the response speed of albino rats that consume alcohol and those that consume water on visual attention using 5-CSRTT. This was confirmed (DF (2, 9) = 0.72, P <.05). Hypothesis 2 stated that albino rats who consumed alcohol will perform better than those who consume water on auditory accuracy using 5-CSRTT. This was also tested but not confirmed (DF (2, 9) = 2.10, P< .05). The third hypothesis which stated that female albino rats who consumed alcohol would not perform better than male albino rats who consumed alcohol on auditory accuracy using 5-CSRTT was tested and not confirmed. (DF (4) = 0.17, P < .05). Data was analyzed using one-way ANOVA and T-test for independent measures. It was therefore recommended that government policies and programs should be directed at reducing to the barest minimum the rate of alcohol consumption especially among males as it is detrimental to the human auditory attentional organ. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alcohol" title="alcohol">alcohol</a>, <a href="https://publications.waset.org/abstracts/search?q=attention" title=" attention"> attention</a>, <a href="https://publications.waset.org/abstracts/search?q=influence" title=" influence"> influence</a>, <a href="https://publications.waset.org/abstracts/search?q=rats" title=" rats"> rats</a>, <a href="https://publications.waset.org/abstracts/search?q=Wistar" title=" Wistar"> Wistar</a> </p> <a href="https://publications.waset.org/abstracts/77351/influence-of-alcohol-consumption-on-attention-in-wistar-albino-rats" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77351.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">263</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">372</span> Leveraging Remote Sensing Information for Drought Disaster Risk Management</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Israel%20Ropo%20Orimoloye">Israel Ropo Orimoloye</a>, <a href="https://publications.waset.org/abstracts/search?q=Johanes%20A.%20Belle"> Johanes A.

With Terra instrument's performance and the free distribution of its products, this study utilised Terra MOD13Q1 satellite data to assess drought disaster events and its spatiotemporal patterns over the Free State Province of South Africa between 2001 and 2019 for summer, autumn, winter, and spring seasons. The study also used high-resolution downscaled climate change projections under three representative concentration pathways (RCP). Three future periods comprising the short (the 2030s), medium (2040s), and long term (2050s) compared to the current period are analysed to understand the potential magnitude of projected climate change-related drought. The study revealed that the year 2001 and 2016 witnessed extreme drought conditions where the drought index is between 0 and 20% across the entire province during summer, while the year 2003, 2004, 2007, and 2015 observed severe drought conditions across the region with variation from one part to the another. The result shows that from -24.5 to -25.5 latitude, the area witnessed a decrease in precipitation (80 to 120mm) across the time slice and an increase in the latitude -26° to -28° S for summer seasons, which is more prominent in the year 2041 to 2050. This study emphasizes the strong spatio-environmental impacts within the province and highlights the associated factors that characterise high drought stress risk, especially on the environment and ecosystems. This study contributes to a disaster risk framework to identify areas for specific research and adaptation activities on drought disaster risk and for environmental planning in the study area, which is characterised by both rural and urban contexts, to address climate change-related drought impacts. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=remote%20sensing" title="remote sensing">remote sensing</a>, <a href="https://publications.waset.org/abstracts/search?q=drought%20disaster" title=" drought disaster"> drought disaster</a>, <a href="https://publications.waset.org/abstracts/search?q=climate%20scenario" title=" climate scenario"> climate scenario</a>, <a href="https://publications.waset.org/abstracts/search?q=assessment" title=" assessment"> assessment</a> </p> <a href="https://publications.waset.org/abstracts/131504/leveraging-remote-sensing-information-for-drought-disaster-risk-management" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131504.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">187</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">371</span> Optimization of Solar Chimney Power Production</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Olusola%20Bamisile">Olusola Bamisile</a>, <a href="https://publications.waset.org/abstracts/search?q=Oluwaseun%20Ayodele"> Oluwaseun Ayodele</a>, <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20Dagbasi"> Mustafa Dagbasi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The main objective of this research is to optimize the power produced by a solar chimney wind turbine.

The post 9/11 literature that reflects these characteristics retells the experiences of those who are, whether directly or indirectly, involved in the globalized catastrophes of enlarging and endangering their boundaries and consequences. With an Irish-Turkish origin, a Dutch and British educational background, and as an American green-card holder, Joseph O’Neill challenges this changing circumstances of the expanding crisis. In his controversial novel, Netherland (2008), O’Neill embodies the deeply-rooted compromises, the transplanted conflicts, and human internalized crisis in post 9/11 New York City. O’Neill presents to us the transition between Netherland to New York with a post-colonial perspective. This internalized conflicts are revised in The Dog (2014) in which a newly-constructing and expanding global city of gold, Dubai, represents the transitional location from New York City. Through these two novels, words and voices are migrating beyond cultural and political boundaries and discussing what a collective mind embodies in this globalized society.   <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=American%20literature" title="American literature">American literature</a>, <a href="https://publications.waset.org/abstracts/search?q=global%20literature" title=" global literature"> global literature</a>, <a href="https://publications.waset.org/abstracts/search?q=cultural%20studies" title=" cultural studies"> cultural studies</a>, <a href="https://publications.waset.org/abstracts/search?q=political%20science" title=" political science"> political science</a> </p> <a href="https://publications.waset.org/abstracts/47081/migrating-words-and-voices-in-joseph-oneills-netherland-and-the-dog" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47081.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">367</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">368</span> The Impact of Electronic Commerce on Organisational Efectiveness: A Study of Zenith Bank Plc</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Olusola%20Abiodun%20Arinde">Olusola Abiodun Arinde</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research work was prompted by the very important role e-commerce plays in every organization, be it private or public.

Besides these, the protective scheme employed on the low voltage network which is the fuse cannot be monitored remotely such that in the event of sustained fault, the utility will have to rely solely on the complaint brought by customers for loss of supply and this tends to increase the length of outages. A microcontroller based fault detection scheme is hereby developed to detect low voltage and high voltage fault conditions which are common faults on this network. Voltages below 198V and above 242V on the distribution feeders are classified and detected as low voltage and high voltages respectively.

Strategic leadership is seen as a potent source of management development and sustained competitive advantage for both employee and organizational performance. There is currently a charge on leaders as a major cause of organizational failure. Stakeholders give what they can afford, not necessarily what the organization needs and impose operational and financial decisions on the leaders, 200 respondents were fit for the analysis from the six geo-political regions in Nigeria. The selection was done equally among various parastatals through random sampling technique from the south-south, south-east, south-west, north-east, north-west and north-central. A descriptive research of the survey was employed. The data were subjected to t-test analysis and correlation and regression were used for the analysis. The findings revealed that there is a strong relationship and impact between a strategic leader and corporate performance. Recommendations were made based on the findings that strategic leaders should be given the blueprint, company’s policy and the stakeholders’ expectation within a time frame the work is to be carried out. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=time" title="time">time</a>, <a href="https://publications.waset.org/abstracts/search?q=strategic" title=" strategic"> strategic</a>, <a href="https://publications.waset.org/abstracts/search?q=organization" title=" organization"> organization</a>, <a href="https://publications.waset.org/abstracts/search?q=stakeholder" title=" stakeholder"> stakeholder</a>, <a href="https://publications.waset.org/abstracts/search?q=leader" title=" leader"> leader</a>, <a href="https://publications.waset.org/abstracts/search?q=performance" title=" performance"> performance</a> </p> <a href="https://publications.waset.org/abstracts/32016/impact-of-strategic-leadership-on-corporate-performance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32016.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">305</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">363</span> A Feasibility Study of Replacing High Pressure Mercury Vapor and Sodium Vapor Lamp Street Lighting Bulbs with LEDs in Turkish Republic of Northern Cyprus</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Olusola%20Olorunfemi%20Bamisile">Olusola Olorunfemi Bamisile</a>, <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20Dagbasi"> Mustafa Dagbasi</a>, <a href="https://publications.waset.org/abstracts/search?q=Serkan%20Abbasoglu"> Serkan Abbasoglu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Feasibility of an Energy Audit program is the main aim of this paper.

In this work, the impact of ethanol-gasoline blend on the exhaust emission of a single cylinder non-mobile spark ignition engine was investigated. Gasoline was blended with 5 – 20% of ethanol sourced from the open market (bought off the shelf) in an interval of 5%. The results of the emission characteristics of the exhaust gas from the combustion of the ethanol-gasoline blends showed that increasing the percentage of ethanol in the blend decreased CO emission by between 2.12% and 52.29% and HC emissions by between12.14% and 53.24%, but increased CO2 and NOx emissions by between 25% to 56% and 59% to 60% respectively. E15 blend is preferred above other blends at no-load and across all the load variations. However its NOx emission was the highest when compared with other samples.

A hybrid solar assisted air conditioning system is designed to produce 30kW cooling capacity and R744 (CO₂) is used as a refrigerant. The effect of discharge pressure on the performance of the system is studied. The subcool temperature, evaporating temperature (5°C) and suction gas return temperature (12°C) are kept constant for the four different discharge pressures considered. The cooling gas temperature is set at 25°C, and the discharge pressure includes 80, 85, 90 and 95 bars. Copeland Scroll software is used for the simulation. A pressure-enthalpy graph is also used to deduce each enthalpy point while numerical methods were used in making other calculations. From the result of the study, it is observed that a higher COP is achieved with the use of solar assisted systems. As much as 46% of electricity requirements will be save using solar input at compressor stage. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=air%20conditioning" title="air conditioning">air conditioning</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20energy" title=" solar energy"> solar energy</a>, <a href="https://publications.waset.org/abstracts/search?q=performance" title=" performance"> performance</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20saving" title=" energy saving"> energy saving</a> </p> <a href="https://publications.waset.org/abstracts/82514/performance-analysis-of-solar-assisted-air-condition-using-carbon-dioxide-as-refrigerant" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82514.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">146</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">360</span> Impact of Internal Control on Fraud Detection and Prevention: A Survey of Selected Organisations in Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amos%20Olusola%20Akinola">Amos Olusola Akinola</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study is to evaluate the internal control system on fraud prevention in Nigerian business organizations. A survey research was undertaken in five organizations from the banking and manufacturing sectors in Nigeria using the simple random sampling technique and primary data was obtained with the aid structured questionnaire drawn on five likert’s scale. Four Hypotheses were formulated and tested using the T-test Statistics, Correlation and Regression Analysis at 95% confidence interval. It was discovered that internal control has a significant positive relationship with fraud prevention and that a weak internal control system permits fraudulent activities among staff. Based on the findings, it was recommended that organizations should continually and methodically review and evaluate the components of its internal control system whether activities are working as planned or not and that every organization should have pre-determined guidelines for conducting its operations and ensures compliance with these set guidelines while proactive steps should be taken to establish the independence of the internal audit by making the audit reportable to the governing council of an organization and not the chief executive officer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=internal%20control" title="internal control">internal control</a>, <a href="https://publications.waset.org/abstracts/search?q=internal%20system" title=" internal system"> internal system</a>, <a href="https://publications.waset.org/abstracts/search?q=internal%20audit" title=" internal audit"> internal audit</a>, <a href="https://publications.waset.org/abstracts/search?q=fraud%20prevention" title=" fraud prevention"> fraud prevention</a>, <a href="https://publications.waset.org/abstracts/search?q=fraud%20detection" title=" fraud detection"> fraud detection</a> </p> <a href="https://publications.waset.org/abstracts/40751/impact-of-internal-control-on-fraud-detection-and-prevention-a-survey-of-selected-organisations-in-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40751.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">384</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">359</span> Evaluation of the Potability Qualities of Pretreated Distilled Water Produced from Biomass Fuelled Water Distiller</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=E.%20I.%20Oluwasola">E.

The water samples were subjected to Microbial, Physicochemical and Minerals analyses for comparison with NAFDAC and WHO Standards for potable water. The results of the physicochemical and microbiological properties of the raw water(A), and the two distilled water samples (B; distill water without pretreatment) and (C; distill water with pretreatment) showed reduction in most of the quality parameters evaluated in the distilled water samples to the level that conforms to the W.H.O standards for drinking water however, lower values were obtained for the pretreated distilled water sample. The values of 0.0016mg/l, 0.0052mg/l and 0.0528mg/l for the arsenic, chromium and lead content respectively in the raw water were within the permissible limit specified by WHO however; the values of cadmium (0.067mg/l) and mercury (0.0287mg/l) are above the maximum tolerable for drinking water thus, making the raw water unsafe for human consumption. Similarly, the high total plate count (278cfu /ml) and coliform count (1100/100ml) indicate that the raw water is potentially harmful while the distilled water samples showed nil coliform count and low total plate count (35cfu/ml,18cfu/ml) for B and C respectively making the distilled water microbiologically safer for human consumption. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biomass" title="biomass">biomass</a>, <a href="https://publications.waset.org/abstracts/search?q=distillation" title=" distillation"> distillation</a>, <a href="https://publications.waset.org/abstracts/search?q=mineral" title=" mineral"> mineral</a>, <a href="https://publications.waset.org/abstracts/search?q=potable" title=" potable"> potable</a>, <a href="https://publications.waset.org/abstracts/search?q=physicochemical" title=" physicochemical"> physicochemical</a> </p> <a href="https://publications.waset.org/abstracts/20798/evaluation-of-the-potability-qualities-of-pretreated-distilled-water-produced-from-biomass-fuelled-water-distiller" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20798.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">496</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">358</span> An Adaptive Distributed Incremental Association Rule Mining System </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adewale%20O.%20Ogunde">Adewale O.

One of such challenges that have not received the attention of many researchers is the inability of existing systems to adapt to constantly changing databases and mining environments. In this work, an Adaptive Incremental Mining Algorithm (AIMA) is therefore proposed to address these problems. AIMA employed multiple mobile agents for the entire mining process. AIMA was designed to adapt to changes in the distributed databases by mining only the incremental database updates and using this to update the existing rules in order to improve the overall response time of the DARM system. In AIMA, global association rules were integrated incrementally from one data site to another through Results Integration Coordinating Agents. The mining agents in AIMA were made adaptive by defining mining goals with reasoning and behavioral capabilities and protocols that enabled them to either maintain or change their goals. AIMA employed Java Agent Development Environment Extension for designing the internal agents’ architecture. Results from experiments conducted on real datasets showed that the adaptive system, AIMA performed better than the non-adaptive systems with lower communication costs and higher task completion rates. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adaptivity" title="adaptivity">adaptivity</a>, <a href="https://publications.waset.org/abstracts/search?q=data%20mining" title=" data mining"> data mining</a>, <a href="https://publications.waset.org/abstracts/search?q=distributed%20association%20rule%20mining" title=" distributed association rule mining"> distributed association rule mining</a>, <a href="https://publications.waset.org/abstracts/search?q=incremental%20mining" title=" incremental mining"> incremental mining</a>, <a href="https://publications.waset.org/abstracts/search?q=mobile%20agents" title=" mobile agents"> mobile agents</a> </p> <a href="https://publications.waset.org/abstracts/10014/an-adaptive-distributed-incremental-association-rule-mining-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10014.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">393</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">357</span> An Approach to Control Electric Automotive Water Pumps Deploying Artificial Neural Networks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gabriel%20S.%20Adesina">Gabriel S.

The electric Automotive Water Pump (AWP) has been introduced as an alternative to IC engine belt-driven pump systems. However, current control methods for AWPs typically employ fixed gain settings, which are not ideal for the varying conditions of dynamic vehicle environments, potentially leading to overheating issues. To overcome the limitations of fixed gain control, this paper proposes implementing an artificial neural network (ANN) for managing the AWP in EHVs. The proposed ANN provides an intelligent, adaptive control strategy that enhances the AWP's performance, supported through MATLAB simulation work illustrated in this paper. Comparative analysis demonstrates that the ANN-based controller surpasses conventional PID and fuzzy logic-based controllers (FLC), exhibiting no overshoot, 0.1secs rapid response, and 0.0696 IAE performance. Consequently, the findings suggest that ANNs can be effectively utilized in EHVs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=automotive%20water%20pump" title="automotive water pump">automotive water pump</a>, <a href="https://publications.waset.org/abstracts/search?q=cooling%20system" title=" cooling system"> cooling system</a>, <a href="https://publications.waset.org/abstracts/search?q=electric%20hybrid%20vehicles" title=" electric hybrid vehicles"> electric hybrid vehicles</a>, <a href="https://publications.waset.org/abstracts/search?q=artificial%20neural%20networks" title=" artificial neural networks"> artificial neural networks</a>, <a href="https://publications.waset.org/abstracts/search?q=PID%20control" title=" PID control"> PID control</a>, <a href="https://publications.waset.org/abstracts/search?q=fuzzy%20logic%20control" title=" fuzzy logic control"> fuzzy logic control</a>, <a href="https://publications.waset.org/abstracts/search?q=IAE" title=" IAE"> IAE</a>, <a href="https://publications.waset.org/abstracts/search?q=MATLAB" title=" MATLAB"> MATLAB</a> </p> <a href="https://publications.waset.org/abstracts/190224/an-approach-to-control-electric-automotive-water-pumps-deploying-artificial-neural-networks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/190224.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">34</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">356</span> Optimized Passive Heating for Multifamily Dwellings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Joseph%20Bostick">Joseph Bostick</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A method of decreasing the heating load of HVAC systems in a single-dwelling model of a multifamily building, by controlling movable insulation through the optimization of flux, time, surface incident solar radiation, and temperature thresholds.

Five hundred and twenty (520) unsexed quail birds of two (2) weeks of age were allotted randomly into nine (9) groups with 3 replicates each in a 3x3 factorial arrangement (3 stocking density levels and 3 graded vitamin C levels) with densities of 150, 120, 90 cm2/bird(11, 16, 21 birds). During the five weeks growing trial (2- 6 weeks), results showed that stocking density had significant effects on final weight (131.59g compared to 111.10g for the lowest), total and daily weight gain. No significance difference was observed for feed conversion ratio, age at first lay and first egg weight. Observations on haematological parameters (packed cell volume (PCV), total protein (TP), haemoglobin, red blood cell (RBC), lymphocyte, heterophil) on stocking density showed no significant differences. Vitamin C supplementation at 50mg/kg and 100mg/kg did not have any significant effect on the growth performance parameters of growing quails. Stocking density at 150cm2/bird had a better performance with or without vitamin C supplementation hence it is recommended that stocking rates of quails between the ages of 2 – 6 weeks should not be below 150cm2/bird. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anti-oxidants" title="anti-oxidants">anti-oxidants</a>, <a href="https://publications.waset.org/abstracts/search?q=performance" title=" performance"> performance</a>, <a href="https://publications.waset.org/abstracts/search?q=stress" title=" stress"> stress</a>, <a href="https://publications.waset.org/abstracts/search?q=stocking%20density" title=" stocking density"> stocking density</a> </p> <a href="https://publications.waset.org/abstracts/19499/effect-of-varying-stocking-densities-and-vitamin-c-ascorbic-acid-supplementation-on-growth-performance-of-japanese-quails" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19499.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">646</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">354</span> Allelopathic Effect of Duranta Repens on Salinity-Stressed Solanum Lycopersicum Seedlings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Olusola%20Nafisat%20Omoniyi">Olusola Nafisat Omoniyi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aqueous extract of Duranta repens leaves was investigated for its allelopathic effect on Solanum lycopersicum Seedlings germinated and grown under salinity condition. The study was carried out using both laboratory petri dish and pot assays to simulate the plant’s natural environmental conditions. The experiment consisted of 5 groups (1-5), each containing 5 replicates (of 10 seeds). Group 1 was treated with distilled water; Group 2 was treated with 5 mM NaCl; Group 3 was treated with the Extract, Group 4 was treated with a mixture of 5 mM NaCl and the Extract (2:1 v/v), and Group 5 was treated with a mixture of 5 mM NaCl and the Extract (1:2 v/v). The results showed that treatment with NaCl caused significant reductions in germination, growth parameters (plumule and radicle lengths), and chlorophyll concentration of S. lycopersicum seedlings when compared to those treated with D. rupens aqueous leaf extract. Salinity also caused an increase in malondialdehyde and proline concentrations and lowered the activity of superoxide dismutase. However, in the presence of the extract, the adverse effects of the NaCl were attenuated, implying that the extract improved tolerance of S. lycopersicum seedlings. In conclusion, the findings of this study show that the extract is very important in the optimal growth of the plant in saline soil, which has become useful for the management of soil salinity problems. <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=allelopathic" title=" allelopathic"> allelopathic</a>, <a href="https://publications.waset.org/abstracts/search?q=salinity" title=" salinity"> salinity</a>, <a href="https://publications.waset.org/abstracts/search?q=soil" title=" soil"> soil</a>, <a href="https://publications.waset.org/abstracts/search?q=tomato" title=" tomato"> tomato</a>, <a href="https://publications.waset.org/abstracts/search?q=production" title=" production"> production</a>, <a href="https://publications.waset.org/abstracts/search?q=photosynthesis" title=" photosynthesis"> photosynthesis</a> </p> <a href="https://publications.waset.org/abstracts/114419/allelopathic-effect-of-duranta-repens-on-salinity-stressed-solanum-lycopersicum-seedlings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/114419.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">219</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">353</span> Athlete’s Preparation and Quality of Opponent as Determinants of Self-Efficacy among University Athletes in South-West Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Raimi%20Abiodun%20Moronfolu">Raimi Abiodun Moronfolu</a>, <a href="https://publications.waset.org/abstracts/search?q=Anthonia%20Olusola%20Moronfolu"> Anthonia Olusola Moronfolu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this study was to assess athlete’s preparation and quality of opponent as determinants of self-efficacy among university athletes in south-west Nigeria.

Using 2D seismic data and well data interpreted through sequence stratigraphy with integrated seismic attributes analysis with Python Programming and unsupervised Machine Learning, at least six second-order sequences, indicating three main stages of tectono-stratigraphic evolution, were determined: pre-salt syn-rift, post-salt rift climax and post-rift stages. The pre-salt syn-rift stage with KTS1 tectonosequence (Barremian-Aptian) reveals a transform rifting along NE-SW transfer faults associated with N-S to NNE-SSW syn-rift longitudinal faults bounding a NW-SE half-graben filled with alluvial to lacustrine-fan delta deposits. The post-salt rift-climax stage (Lower to Upper Cretaceous) includes two second-order tectonosequences (KTS2 and KTS3) associated with the salt tectonics and Campo High uplift. During the rift-climax stage, the growth of salt diapirs developed syncline withdrawal basins filled by early forced regression, mid transgressive and late normal regressive systems tracts. The early rift climax underlines some fine-grained hangingwall fans or delta deposits and coarse-grained fans from the footwall of fault scarps. The post-rift stage (Paleogene to Neogene) contains at least three main tectonosequences KTS4, KTS5 and KTS6-7. The first one developed some turbiditic lobe complexes considered as mass transport complexes and feeder channel-lobe complexes cutting the unstable shelf edge of the Campo High. The last two developed submarine Channel Complexes associated with lobes towards the southern part and braided delta to tidal channels towards the northern part of the Kribi-Campo sub-basin. The reservoir distribution in the Kribi-Campo sub-basin reveals some channels, fan lobes reservoirs and stacked channels reaching up to the polygonal fault systems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tectono-stratigraphic%20architecture" title="tectono-stratigraphic architecture">tectono-stratigraphic architecture</a>, <a href="https://publications.waset.org/abstracts/search?q=Kribi-Campo%20sub-basin" title=" Kribi-Campo sub-basin"> Kribi-Campo sub-basin</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=pre-salt%20sequences" title=" pre-salt sequences"> pre-salt sequences</a>, <a href="https://publications.waset.org/abstracts/search?q=post-salt%20sequences" title=" post-salt sequences"> post-salt sequences</a> </p> <a href="https://publications.waset.org/abstracts/185081/tectono-stratigraphic-architecture-depositional-systems-and-salt-tectonics-to-strike-slip-faulting-in-kribi-campo-cameroon-atlantic-margin-with-an-unsupervised-machine-learning-approach-west-african-margin" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185081.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">56</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">351</span> Heightening Pre-Service Teachers’ Attitude towards Learning and Metacognitive Learning through Information and Communication Technology: Pre-Service Science Teachers’ Perspective</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abiodun%20Ezekiel%20Adesina">Abiodun Ezekiel Adesina</a>, <a href="https://publications.waset.org/abstracts/search?q=Ijeoma%20Ginikanwa%20Akubugwo"> Ijeoma Ginikanwa Akubugwo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Information and Communication Technology, ICT can heighten pre-service teachers’ attitudes toward learning and metacognitive learning; however, there is a dearth of literature on the perception of the pre-service teachers on heightening their attitude toward learning and metacognitive learning. Thus, this study investigates the perception of pre-service science teachers on heightening their attitude towards learning and metacognitive learning through ICT. Two research questions and four hypotheses guided the research. A mixed methods research was adopted for the study in concurrent triangulation type of integrating qualitative and quantitative approaches to the study. The cluster random sampling technique was adopted to select 250 pre-service science teachers in Oyo township. Two self-constructed instruments: Heightening Pre-service Science Teachers’ Attitude towards Learning and Metacognitive Learning through Information and Communication Technology Scale (HPALMIS, r=.73), and an unstructured interview were used for data collection. Thematic analysis, frequency counts and percentages, t-tests, and analysis of variance were used for data analysis. The perception level of the pre-service science teachers on heightening their attitude towards learning and metacognitive learning through ICT is above average, with the majority perceiving that ICT can enhance their thinking about their learning. The perception was significant (mean=92.68, SD=10.86, df=249, t=134.91, p<.05). The perception was significantly differentiated by gender (t=2.10, df= 248, p<.05) in favour of the female pre-service teachers and based on the first time of ICTs use (F(5,244)= 9.586, p<.05). Lecturers of science and science related courses should therefore imbibe the use of ICTs in heightening pre-service teachers’ attitude towards learning and metacognitive learning. Government should organize workshops, seminars, lectures, and symposia along with professional bodies for the science education lecturers to keep abreast of the trending ICT. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pre-service%20teachers%E2%80%99%20attitude%20towards%20learning" title="pre-service teachers’ attitude towards learning">pre-service teachers’ attitude towards learning</a>, <a href="https://publications.waset.org/abstracts/search?q=metacognitive%20learning" title=" metacognitive learning"> metacognitive learning</a>, <a href="https://publications.waset.org/abstracts/search?q=ICT" title=" ICT"> ICT</a>, <a href="https://publications.waset.org/abstracts/search?q=pre-service%20teachers%E2%80%99%20perspectives" title=" pre-service teachers’ perspectives"> pre-service teachers’ perspectives</a> </p> <a href="https://publications.waset.org/abstracts/154897/heightening-pre-service-teachers-attitude-towards-learning-and-metacognitive-learning-through-information-and-communication-technology-pre-service-science-teachers-perspective" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154897.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">100</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">350</span> Programmable Shields in Space</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tapas%20Kumar%20Sinha">Tapas Kumar Sinha</a>, <a href="https://publications.waset.org/abstracts/search?q=Joseph%20Mathew"> Joseph Mathew</a> </p> <p class="card-text"><strong>Abstract:</strong></p> At the moment earth is in grave danger due to threats of global warming. The temperature of the earth has risen by almost 20C. Glaciers in the Arctic have started to melt. It would be foolhardy to think that this is a small effect and in time it would go away. Global warming is caused by a number of factors. However, one sure and simple way to totally eliminate this problem is to put programmable shields in space. Just as an umbrella blocks sunlight, a programmable shield in space will block sun rays from reaching the earth as in a solar eclipse and cause cooling in the penumbral region just as it happens during an eclipse. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=glaciers" title="glaciers">glaciers</a>, <a
