Production of extension materials has been found to be useful in facilitating the process. Extension materials help to provide information to reach large numbers of farmers quickly and economically. However, as good as extension materials are, previous materials produced are not used by farmers. The reasons for this include lack of involvement of farmers in the production of the extension materials, most of the extension materials are not relevant to the farmers’ environments, the agricultural extension agents lack capacity to prepare the materials, and many extension agents lack commitment. These problems led to this innovative capacity building of extension agents. This innovative approach involves five stages. The first stage is the diagnostic survey of farmers’ environment to collect useful information. The second stage is the development and production of draft extension materials. The third stage is the field testing and evaluation of draft materials by the same farmers that were involved at the diagnostic stage. The fourth stage is the revision of the draft extension materials by incorporating suggestions from farmers. The fifth stage is the action plans. This process improves the capacity of agricultural extension agents in the preparation of extension materials and also promotes engagement of farmers and beneficiaries in the process. The process also makes farmers assume some level of ownership of the exercise and the extension materials. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=capacity%20building" title="capacity building">capacity building</a>, <a href="https://publications.waset.org/abstracts/search?q=extension%20agents" title=" extension agents"> extension agents</a>, <a href="https://publications.waset.org/abstracts/search?q=dissemination" title=" dissemination"> dissemination</a>, <a href="https://publications.waset.org/abstracts/search?q=information%2Ftechnologies" title=" information/technologies"> information/technologies</a> </p> <a href="https://publications.waset.org/abstracts/12624/capacity-building-of-extension-agents-for-sustainable-dissemination-of-agricultural-information-and-technologies-in-developing-countries" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12624.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">360</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">2376</span> Perception of Agricultural Extension Agents of Private Sector Participation in Extension Services in Ogun State, Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=E.%20O.%20Fakoya">E.

Data were collected from 80 respondents with a well-structured questionnaire. The result of the findings showed that there is need for private sector participation in extension services (=4.313), private extension services has facilities than public extension services (=4.97). Private sector participated in extension services by: giving of loans and credits to farmers (=4.50). Major constraints identified by the respondents were: Transportation problem (=2.88) and lack of fund (=2.77) A significant relationship (P<0.05) exists between factors affecting public extension services(r = 0.641, p = 0.00) and private sector participation in extension services. It was concluded from the study that there is need for private sector to participate in extension service in order to improve productivity of the farmers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agricultural%20extension" title="agricultural extension">agricultural extension</a>, <a href="https://publications.waset.org/abstracts/search?q=extension%20agent" title=" extension agent"> extension agent</a>, <a href="https://publications.waset.org/abstracts/search?q=private%20sector" title=" private sector"> private sector</a>, <a href="https://publications.waset.org/abstracts/search?q=perception" title=" perception"> perception</a> </p> <a href="https://publications.waset.org/abstracts/12500/perception-of-agricultural-extension-agents-of-private-sector-participation-in-extension-services-in-ogun-state-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12500.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">588</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">2375</span> Farmers’ Perceptions of Extension Personnel’s Technical Capabilities: Evidence from India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ankit%20Nagar">Ankit Nagar</a>, <a href="https://publications.waset.org/abstracts/search?q=Dinesh%20Kumar%20Nauriyal"> Dinesh Kumar Nauriyal</a>, <a href="https://publications.waset.org/abstracts/search?q=S.%20P.%20Singh"> S.

It is based on primary data collected through an interview schedule in India's Western Uttar Pradesh region. It uses descriptive statistics, factor analysis, and MANOVA to determine the typical farmer's view of an extension worker's technical prowess and behavioural traits, as well as the key factors associated with farmers' perception and the demographic characteristics that affect farmer's perception variations. The vast majority of farmers appear to consider extension personnel's efficiency and accessibility unfavourably. Farmers feel that extension personnel are well-trained notwithstanding their disagreements on the viability of their technical advice. Small and marginal farmers view the effectiveness, objectivity, and cooperativeness of extension agents less favourably than large farmers. This study proposes strategies such as routine follow-ups, practical demonstrations, and regular extension professional training camps as part of a holistic plan to increase farmer trust in the agricultural extension system. In addition, it proposes ensuring their accountability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agriculture%20extension" title="agriculture extension">agriculture extension</a>, <a href="https://publications.waset.org/abstracts/search?q=farmers%E2%80%99%20perception" title=" farmers’ perception"> farmers’ perception</a>, <a href="https://publications.waset.org/abstracts/search?q=extension%20agents" title=" extension agents"> extension agents</a>, <a href="https://publications.waset.org/abstracts/search?q=factor%20analysis" title=" factor analysis"> factor analysis</a> </p> <a href="https://publications.waset.org/abstracts/156711/farmers-perceptions-of-extension-personnels-technical-capabilities-evidence-from-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156711.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">105</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">2374</span> Enhancing Sustainable Stingless Beekeeping Production through Technology Transfer and Human Resource Development in Relationship with Extension Agents Work Performance among Malaysian Beekeepers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ibrahim%20Aliyu%20Isah">Ibrahim Aliyu Isah</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Mansor%20Ismail"> Mohd Mansor Ismail</a>, <a href="https://publications.waset.org/abstracts/search?q=Salim%20Hassan"> Salim Hassan</a>, <a href="https://publications.waset.org/abstracts/search?q=Norsida%20Man"> Norsida Man</a>, <a href="https://publications.waset.org/abstracts/search?q=Oluwatoyin%20Olagunju"> Oluwatoyin Olagunju</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Stingless beekeeping is not only a profitable activity for Malaysian beekeepers but also for the Malaysian economy. However, natural honey has faced some difficulties, which resulted in low production due to a lack of information on improved technology as well as the capacity and potential building of stingless beekeeping farmers, which depend mostly on information received from the extension agents. Hence, it is the responsibility of the extension agents to give useful information on the available technology and develop the capacity of the farmers to make the right decision that will improve their level of production. This study assessed how technology transfer and human resource development skills influence the work performance of the extension agents toward sustainable beekeeping production among beekeepers. The study sought to establish the role of relevant technology transfer and human resource development skills in effective performance. The research design was a descriptive and quantitative survey of stingless beekeepers on technology transfer and human resource development by the extension agent. Data was obtained from 54 beekeeping farmers and was analyzed using descriptive and inferential statistics. The results revealed that technology skill, technology dissemination skill, technology evaluation skill, Decision-making process skill, Leadership development skill and work performance were rated moderate by stingless beekeeping farmers, while Social skill was rated high. A significant and positive correlation (P<0.01) existed between all variables and performance. Regression results showed that leadership development skills, Decision-making process skills, and social skills are significant (P=.05), while technology skills, technology dissemination skills, and technology evaluation skills are not significant. The highest contributing factor is social skill (β=.446). Beekeeping is a profitable project in Malaysia and can be sustained if the extension services and programs are well carried out by competent extension agents and relevant agricultural government agencies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=beekeeping" title="beekeeping">beekeeping</a>, <a href="https://publications.waset.org/abstracts/search?q=extension%20agents" title=" extension agents"> extension agents</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20resource%20development" title=" human resource development"> human resource development</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable" title=" sustainable"> sustainable</a>, <a href="https://publications.waset.org/abstracts/search?q=technology%20transfer" title=" technology transfer"> technology transfer</a>, <a href="https://publications.waset.org/abstracts/search?q=work%20performance" title=" work performance"> work performance</a> </p> <a href="https://publications.waset.org/abstracts/172800/enhancing-sustainable-stingless-beekeeping-production-through-technology-transfer-and-human-resource-development-in-relationship-with-extension-agents-work-performance-among-malaysian-beekeepers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/172800.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">63</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">2373</span> Comparative Analysis of Yield before and after Access to Extension Services among Crop Farmers in Bauchi Local Government Area of Bauchi State, Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=U.%20S.%20Babuga">U.

Data were collected from the study area through questionnaires administered to seventy-five randomly selected respondents. Data were analyzed using descriptive statistics, t-test and regression models. The result disclosed that majority (97%) of the respondent attended one form of school or the other. The majority (78.67%) of the respondents had farm size ranging between 1-3 hectares. The majority of the respondent adopt improved variety of crops, plant spacing, herbicide, fertilizer application, land preparation, crop protection, crop processing and storage of farm produce. The result of the t-test between the yield of respondents before and after access to extension services shows that there was a significant (p<0.001) difference in yield before and after access to extension. It also indicated that farm size was significant (p<0.001) while household size, years of farming experience and extension contact were significant at (p<0.005). The major constraint to adoption of crop production technologies were shortage of extension agents, high cost of technology and lack of access to credit facility. The major pre-requisite for the improvement of extension service are employment of more extension agents or workers and adequate training. Adequate agricultural credit to farmers at low interest rates will enhance their adoption of crop production technologies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=comparative" title="comparative">comparative</a>, <a href="https://publications.waset.org/abstracts/search?q=analysis" title=" analysis"> analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=yield" title=" yield"> yield</a>, <a href="https://publications.waset.org/abstracts/search?q=access" title=" access"> access</a>, <a href="https://publications.waset.org/abstracts/search?q=extension" title=" extension"> extension</a> </p> <a href="https://publications.waset.org/abstracts/47039/comparative-analysis-of-yield-before-and-after-access-to-extension-services-among-crop-farmers-in-bauchi-local-government-area-of-bauchi-state-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47039.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">364</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2372</span> Extension Services Impact On Stingless Bee Production And Profitability In Malaysia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ibrahim%20Aliyu%20Isaha">Ibrahim Aliyu Isaha</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Mansor%20Ismailb"> Mohd Mansor Ismailb </a>, <a href="https://publications.waset.org/abstracts/search?q=Salim%20Hassanc"> Salim Hassanc</a>, <a href="https://publications.waset.org/abstracts/search?q=Norsida%20Bint%20Man"> Norsida Bint Man</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Global and National income derive from a stingless beekeeping project is a new source of wealth to Malaysia.

A common specie, Trigona itama, production through effective utilization of highly competent agents of extension services led to high increase of output that guaranteed high income and sustainability to farmers throughout the study areas. A study on impacts of extension services on stingless bee production and its profitability and sustainability in both Peninsular Malaysia and East (Sarawak) Malaysia was conducted with the following objectives: (i) to examined various impacts of extension services on sustainability as variables in enhancing stingless beekeeping production for positive profitability. (ii) to determine the profitability and sustainability of stingless beekeeping production in the study area through transfer of technology and human resources development. The study covers a sample of beekeepers in ten states of Peninsular Malaysia and Sarawak. The sample size of 87 respondents were selected out of the population and 54 of filled questionnaires were retrieved. Capital budgeting analysis was carried out and economic performance was evaluated. Data collected was analysed using SPSS version 23.0. Correlation and Regression analyses were used. The capital budgeting analysis and government incentive schemes was incorporated in the applied projection of stingless bee farms. The result of Net Present Value (NPV) is determined as an accepted projection to the financial appraisal. The NPV in the study indicated positive outcome of production that can generate positive income and indicated efficient yield of investment and Profitability index (PI).

This shows the critical role and potentials of the agricultural sector in helping to achieve Ghana’s vision 2030. With the current threat of climate change and advancements in technology, agricultural extension is not just about technology transfer and improvements in productivity, but it is also about improving the managerial and technical skills of farmers. In Ghana, the government of Ghana as well as other players in the sector like; non-governmental organizations, NGOs, local and international funding agencies, for decades now, have made capacity-building-investments in smallholder farmers by way of extension services delivery. This study sought to compare the technical efficiency of farmers who have access to agricultural extension and farmers who do not in Ghana. The study employed the stochastic meta-frontier model to analyze household survey data comprising 300 smallholder cassava farmers from the Fanteakwa district of Ghana. The farmers were selected through a two-stage sampling technique where 5 communities were purposively selected in the first stage and then 60 smallholder cassava farmers were randomly selected from each of the 5 communities. Semi-structured questionnaires were used to collect data on farmers’ socioeconomic and farm-level characteristics. The results showed that farmers who have access to agricultural extensions services have higher technical efficiencies (TE) and produce much closer to their meta-production frontiers (higher technology gap ratios (TGR) than farmers who do not have access to such extension services. Furthermore, experience in cassava cultivation and formal education significantly improves the technical efficiencies of farmers. The study recommends that the mode and scope of agricultural extension service delivery in the country should be enhanced to ensure that smallholder farmers have easy access to extension agents. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agricultural%20extension" title="agricultural extension">agricultural extension</a>, <a href="https://publications.waset.org/abstracts/search?q=Ghana" title=" Ghana"> Ghana</a>, <a href="https://publications.waset.org/abstracts/search?q=smallholder%20farmers" title=" smallholder farmers"> smallholder farmers</a>, <a href="https://publications.waset.org/abstracts/search?q=stochastic%20meta-frontier%20model" title=" stochastic meta-frontier model"> stochastic meta-frontier model</a>, <a href="https://publications.waset.org/abstracts/search?q=technical%20efficiency" title=" technical efficiency"> technical efficiency</a> </p> <a href="https://publications.waset.org/abstracts/115110/effect-of-agricultural-extension-services-on-technical-efficiency-of-smallholder-cassava-farmers-in-ghana-a-stochastic-meta-frontier-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/115110.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">2367</span> Perceived Effects of Work-Family Balance on Employee’s Job Satisfaction among Extension Agents in Southwest Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=B.%20G.%20Abiona">B.

A multistage sampling technique was used to select 256 respondents for the study. Data on personal characteristics, work-family balance domain, and job satisfaction were collected. The collected data were analysed using descriptive statistics, Chi-square, Pearson Product Moment Correlation (PPMC), multiple linear regression, and Student T-test. Results revealed that the mean age of the respondents was 40 years; the majority (59.3%) of the respondents were male, and slightly above half (51.6%) of the respondents had MSc as their highest academic qualification. Findings revealed that turnover intention (x ̅ = 3.20) and work-role conflict (x ̅ = 3.06) were the major perceived work-family balance domain in the studied areas. Further, the result showed that the respondents have a high (79%) level of job satisfaction. Multiple linear regression revealed that job involvement (ß=0.167, p<0.01) and work-role conflict (ß= -0.221, p<0.05) contributed significantly to employees’ level of job satisfaction. The results of the Student T-test revealed a significant difference in the perceived work-family balance domain (t = 0.43, p<0.05) between the two studied areas. The study concluded that work-role conflict among employees causes work-family imbalance and, therefore, negatively affects employees’ job satisfaction. The definition of job design among the respondents that will create a balance between work and family is highly recommended. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=work-life" title="work-life">work-life</a>, <a href="https://publications.waset.org/abstracts/search?q=conflict" title=" conflict"> conflict</a>, <a href="https://publications.waset.org/abstracts/search?q=job%20satisfaction" title=" job satisfaction"> job satisfaction</a>, <a href="https://publications.waset.org/abstracts/search?q=extension%20agent" title=" extension agent"> extension agent</a> </p> <a href="https://publications.waset.org/abstracts/165849/perceived-effects-of-work-family-balance-on-employees-job-satisfaction-among-extension-agents-in-southwest-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165849.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">94</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">2366</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">2365</span> Extension Services' Needs of Small Farmers in Biliran Province, Philippines</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mario%20C.%20Nierras">Mario C.

It also sought to find out other issues/concerns of the small farmers. Extension services’ needs of small farmers were gathered through personal interviewing and observational analysis of randomly-selected small farmers in Biliran, Philippines. Biliran small farmers extension services’ needs include: raising fruits, raising legumes, raising vegetables, raising swine, raising cattle, and raising chicken (as priority broad skills). For the specific skills, diagnosing symptoms on fertilizer deficiencies, controlling plant pests and diseases, diagnosing signs on specific pest and disease damage, controlling animal pests and diseases, and doing artificial insemination were the priority skills. They considered an on-farm trial of new technology as most needed to be coupled with industry and quality-orientedness, as positive behaviors needed in farming success. The farmers still adhere to the so-called wait-and-see attitude, thus they are more convinced to follow a particular technology if they see a concrete result of the introduced changes. Technical needs prioritization of Biliran small farmers showed that they have a real need for crop and animal production skills to include the other issues/concerns. Extension service program planning for small farmers should be patterned after their technical needs giving due attention to some issues/concerns so that extension work could deliver the right skills for the right needs of the farmers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=extension" title="extension">extension</a>, <a href="https://publications.waset.org/abstracts/search?q=extension%20service" title=" extension service"> extension service</a>, <a href="https://publications.waset.org/abstracts/search?q=extension%20service%20needs" title=" extension service needs"> extension service needs</a>, <a href="https://publications.waset.org/abstracts/search?q=extension%20service%20program" title=" extension service program"> extension service program</a>, <a href="https://publications.waset.org/abstracts/search?q=farmers" title=" farmers"> farmers</a>, <a href="https://publications.waset.org/abstracts/search?q=small%20farmers" title=" small farmers"> small farmers</a>, <a href="https://publications.waset.org/abstracts/search?q=marginal%20farmers" title=" marginal farmers"> marginal farmers</a> </p> <a href="https://publications.waset.org/abstracts/24749/extension-services-needs-of-small-farmers-in-biliran-province-philippines" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24749.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">436</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">2364</span> Bridgeless Boost Power Factor Correction Rectifier with Hold-Up Time Extension Circuit</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chih-Chiang%20Hua">Chih-Chiang Hua</a>, <a href="https://publications.waset.org/abstracts/search?q=Yi-Hsiung%20Fang"> Yi-Hsiung Fang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yuan-Jhen%20Siao"> Yuan-Jhen Siao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A bridgeless boost (BLB) power factor correction (PFC) rectifier with hold-up time extension circuit is proposed in this paper.

We develop a within-day approach for multi-agent simulation to evaluate the behavior of the agents, under comprehensive scenarios through various information exposure, equilibrium, and non-equilibrium scenarios. In particular, we quantify the effects of information strategies in disruption situation on passengers’ satisfaction, number of involved agents, and the caused delay. An agent-based micro-simulation model (MATSim) is applied for the city of Zürich, Switzerland, for the purpose of activity-based simulation in a multimodal network. Statistic outcome is analysed for all the agents who may be involved in the disruption. Agents’ movement in the public transport network illustrates agents’ adaptations to available information about the disruption. Agents’ delays and utility reveal that information significantly affects agents’ satisfaction and delay in public transport disruption. Besides, while the earlier availability of the information causes the fewer consequent delay for the involved agents, however, it also leads to more amount of affected agents. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agent-based%20simulation" title="agent-based simulation">agent-based simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=disruption%20management" title=" disruption management"> disruption management</a>, <a href="https://publications.waset.org/abstracts/search?q=passengers%E2%80%99%20behavior%20simulation" title=" passengers’ behavior simulation"> passengers’ behavior simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20transport" title=" public transport"> public transport</a> </p> <a href="https://publications.waset.org/abstracts/122394/passengers-behavior-analysis-under-the-public-transport-disruption-an-agent-based-simulation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/122394.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">152</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2361</span> Farmers’ Access to Agricultural Extension Services Delivery Systems: Evidence from a Field Study in India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ankit%20Nagar">Ankit Nagar</a>, <a href="https://publications.waset.org/abstracts/search?q=Dinesh%20Kumar%20Nauriyal"> Dinesh Kumar Nauriyal</a>, <a href="https://publications.waset.org/abstracts/search?q=Sukhpal%20Singh"> Sukhpal Singh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper examines the key determinants of farmers’ access to agricultural extension services, sources of agricultural extension services preferred and accessed by the farmers. An ordered logistic regression model was used to analyse the data of the 360 sample households based on a primary survey conducted in western Uttar Pradesh, India. The study finds that farmers' decision to engage in the agricultural extension programme is significantly influenced by factors such as education level, gender, farming experience, social group, group membership, farm size, credit access, awareness about the extension scheme, farmers' perception, and distance from extension sources. The most intriguing finding of this study is that the progressive farmers, which have long been regarded as a major source of knowledge diffusion, are the most distrusted sources of information as they are suspected of withholding vital information from potential beneficiaries. The positive relationship between farm size and ‘Access’ underlines that the extension services should revisit their strategies for targeting more marginal and small farmers constituting over 85 percent of the agricultural households by incorporating their priorities in their outreach programs. The study suggests that marginal and small farmers' productive potential could still be greatly augmented by the appropriate technology, advisory services, guidance, and improved market access. Also, the perception of poor quality of the public extension services can be corrected by initiatives aimed at building up extension workers' capacity. <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=access" title=" access"> access</a>, <a href="https://publications.waset.org/abstracts/search?q=extension%20services" title=" extension services"> extension services</a>, <a href="https://publications.waset.org/abstracts/search?q=ordered%20logistic%20regression" title=" ordered logistic regression"> ordered logistic regression</a> </p> <a href="https://publications.waset.org/abstracts/137821/farmers-access-to-agricultural-extension-services-delivery-systems-evidence-from-a-field-study-in-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137821.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">214</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">2360</span> Analysis of Farmer's Involvement in Public and Private Extension Services in Southwestern Nigeria </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20O.%20Ayansina">S.

This study was designed to examine farmers’ involvement in public and private extension services in southwestern Nigeria, specifically to explore the farmers’ participation in the two types of organizations involved. It also evaluates the performances of personnel in the organizations. A multi-stage random sampling technique was used to select 30 respondents from each of the three selected organizations in Ogun, Osun and Oyo states in Southwestern Nigeria. Data was collected with interview schedule and analyzed both at descriptive and inferential levels. Kruskal Wallis one-way Analysis of variance was used to test the differences between the participation of beneficiaries who are farmers under the public and private extension services and the level of benefit accrued to them from the various extension organizations involved in the study. Results revealed that private extension organizations were performing better and were more preferred by the beneficiaries. Results of the tested hypotheses as shown by Kruskal Wallis test of difference (x2 = 0.709) S no significant difference between farmers’ participation in the extension services of public and private organizations but however showed significant difference (X2 =12.074) in the benefits achieved by respondents in the two organizations. These include: increased quantity of crop produced, farm income, skill acquisition, and improved education in private extension organizations. Based on this result, it could be inferred that beneficiaries generally preferred private extension organizations because of their effectiveness and vibrancy in programme administration. Public extension is therefore recommended for general overhauling and possibly privatization in order to cater for teeming population of farmers demanding for efficient and functional extension services to better their lots in production, processing and marketing of agricultural produce. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=public%20and%20private%20involvement" title="public and private involvement">public and private involvement</a>, <a href="https://publications.waset.org/abstracts/search?q=extension%20services" title=" extension services"> extension services</a>, <a href="https://publications.waset.org/abstracts/search?q=farmers%27%20participation" title=" farmers' participation"> farmers' participation</a> </p> <a href="https://publications.waset.org/abstracts/26130/analysis-of-farmers-involvement-in-public-and-private-extension-services-in-southwestern-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26130.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">404</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">2359</span> Extension of Positive Linear Operator</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Manal%20Azzidani">Manal Azzidani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research consideres the extension of special functions called Positive Linear Operators. the bounded linear operator which defined from normed space to Banach space will extend to the closure of the its domain, And extend identified linear functional on a vector subspace by Hana-Banach theorem which could be generalized to the positive linear operators. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=extension" title="extension">extension</a>, <a href="https://publications.waset.org/abstracts/search?q=positive%20operator" title=" positive operator"> positive operator</a>, <a href="https://publications.waset.org/abstracts/search?q=Riesz%20space" title=" Riesz space"> Riesz space</a>, <a href="https://publications.waset.org/abstracts/search?q=sublinear%20function" title=" sublinear function"> sublinear function</a> </p> <a href="https://publications.waset.org/abstracts/33220/extension-of-positive-linear-operator" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33220.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">517</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">2358</span> Brand Extension and Customer WOM: Evidence from the Sports Industry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jim%20Shih-Chiao%20Chin">Jim Shih-Chiao Chin</a>, <a href="https://publications.waset.org/abstracts/search?q=Yu%20Ting%20Yeh"> Yu Ting Yeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Shui%20Lien%20Chen"> Shui Lien Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Yi-Fen%20Tsai"> Yi-Fen Tsai </a> </p> <p class="card-text"><strong>Abstract:</strong></p> his study is taking Adidas Company as the object, explored the brand awareness directly or indirectly affects brand affect and word of mouth.

The government of South Africa has shown a commitment to provide extensive support to farmers by the means of disseminating information and other agricultural facilities. This qualitative study on the experiences of extension officers on the provision of agricultural facilities to rural farmers towards improving agricultural practice was conducted in Msinga Local Municipality. The data was collected through the use of semi-structured interviews with extension officers who were sampled using the purposive sampling method. The qualitative data was analysed through the use of content analysis. The critical part of the findings reveals that the availability of arable land for agricultural practice, availability of agricultural schemes and availability of proper functioning community gardens were indicators of the high level of agricultural practice in the Msinga area. Therefore, the extension officers from the municipality department have shown to provide the agricultural budget to support rural farmers. Whereas, the department of agriculture provides well knowledgeable staff to train farmers about the process of farming and how they can address issues of livestock and crop diseases and also adapting to issues of climate change. The rural farmers, however, find it very difficult to learn and put into practice things that were thought by extension officers during training. There is, therefore, a need for recruitment of more extension staff and the involvement of Non-Government Organizations to increase access to extension facilities to the farmers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agricultural%20facilities" title="agricultural facilities">agricultural facilities</a>, <a href="https://publications.waset.org/abstracts/search?q=agricultural%20practice" title=" agricultural practice"> agricultural practice</a>, <a href="https://publications.waset.org/abstracts/search?q=extension%20officers" title=" extension officers"> extension officers</a>, <a href="https://publications.waset.org/abstracts/search?q=rural%20farmers" title=" rural farmers"> rural farmers</a> </p> <a href="https://publications.waset.org/abstracts/120911/experiences-of-extension-officers-on-the-provision-of-agricultural-facilities-to-rural-farmers-towards-improving-agricultural-practice-in-south-africa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/120911.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">145</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">2356</span> Agricultural Extension Workers’ Education in Indonesia - Roles of Distance Education</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adhi%20Susilo">Adhi Susilo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper addresses the roles of distance education in the agricultural extension workers’ education. Agriculture plays an important role in both poverty reduction and economic growth. The technology of agriculture in the developing world should change continuously to keep pace with rising populations and rapidly changing social, economic, and environmental conditions. Therefore, agricultural extension workers should have several competencies in order to carry out their duties properly. One of the essential competencies that they must possess is the professional competency that is directly related to their duties in carrying out extension activities. Such competency can be acquired through studying at Universitas Terbuka (UT). With its distance learning system, agricultural extension workers can study at UT without leaving their duties. This paper presenting sociological analysis and lessons learnt from the specific context of Indonesia. Diversities in geographic, demographic, social cultural and economic conditions of the country provide specific challenges for its distance education practice and the process of social transformation to which distance education can contribute. Extension officers used distance education for personal benefits and increased professional productivity. An increase in awareness is important for the further adoption of distance learning for extension purposes. Organizations in both the public and private sector must work to increase knowledge of ICTs for the benefit of stakeholders. The use of ICTs can increase productivity for extensions officers and expand educational opportunities for learners. The use of distance education by extension to disseminate educational materials around the world is widespread. Increasing awareness and use of distance learning can lead to more productive relationships between extension officers and agricultural stakeholders. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agricultural%20extension" title="agricultural extension">agricultural extension</a>, <a href="https://publications.waset.org/abstracts/search?q=demographic%20and%20geographic%20condition" title=" demographic and geographic condition"> demographic and geographic condition</a>, <a href="https://publications.waset.org/abstracts/search?q=distance%20education" title=" distance education"> distance education</a>, <a href="https://publications.waset.org/abstracts/search?q=ICTs" title=" ICTs"> ICTs</a> </p> <a href="https://publications.waset.org/abstracts/18747/agricultural-extension-workers-education-in-indonesia-roles-of-distance-education" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18747.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">515</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">2355</span> Inferential Reasoning for Heterogeneous Multi-Agent Mission</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sagir%20M.%20Yusuf">Sagir M.

Bayesian Belief Network (BBN) was used in modeling the agents' belief conflict due to sensor variations. Simulation experiments were designed, and cases from agents’ missions were used in training the BBN using gradient descent and expectation-maximization algorithms. The output network is a well-trained BBN for making inferences for both agents and human experts. We claim that the Bayesian learning algorithm prediction capacity improves by the number of training data and argue that it enhances multi-agents robustness and solve agents’ sensor conflicts. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=distributed%20constraint%20optimization%20problem" title="distributed constraint optimization problem">distributed constraint optimization problem</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-agent%20system" title=" multi-agent system"> multi-agent system</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-robot%20coordination" title=" multi-robot coordination"> multi-robot coordination</a>, <a href="https://publications.waset.org/abstracts/search?q=autonomous%20system" title=" autonomous system"> autonomous system</a>, <a href="https://publications.waset.org/abstracts/search?q=swarm%20intelligence" title=" swarm intelligence"> swarm intelligence</a> </p> <a href="https://publications.waset.org/abstracts/116896/inferential-reasoning-for-heterogeneous-multi-agent-mission" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/116896.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">154</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">2354</span> Knowledge Management and Tourism: An Exploratory Study Applied to Travel Agents in Egypt</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Soliman">Mohammad Soliman</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20A.%20Abou-Shouk"> Mohamed A.

It has become an important tool to improve performance in tourism enterprises. This includes improving decision-making, developing customer services, and increasing sales and profits. Knowledge management adoption depends on human, organizational and technological factors. This study aims to explore the concept of knowledge management in travel agents in Egypt. It explores the requirements of adoption and its impact on performance in these agencies. The study targets Category A travel agents in Egypt. The population of the study encompasses Category A travel agents having online presence. An online questionnaire is used to collect data from managers of travel agents. This study is useful for travel agents who are in urgent need to restructure their intermediary role and support their survival in the global travel market. The study sheds light on the requirements of adoption and the expected impact on performance. This could help travel agents identify their situation and the determine the extent to which they are ready to adopt knowledge management. This study is contributing to knowledge by providing insights from the tourism sector in a developing country where the concept of knowledge management is still in its infancy stages. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=knowledge%20management" title="knowledge management">knowledge management</a>, <a href="https://publications.waset.org/abstracts/search?q=knowledge%20management%20adoption" title=" knowledge management adoption"> knowledge management adoption</a>, <a href="https://publications.waset.org/abstracts/search?q=performance" title=" performance"> performance</a>, <a href="https://publications.waset.org/abstracts/search?q=travel%20agents" title=" travel agents"> travel agents</a> </p> <a href="https://publications.waset.org/abstracts/36812/knowledge-management-and-tourism-an-exploratory-study-applied-to-travel-agents-in-egypt" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36812.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">397</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2353</span> Probabilistic Gathering of Agents with Simple Sensors: Distributed Algorithm for Aggregation of Robots Equipped with Binary On-Board Detectors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ariel%20Barel">Ariel Barel</a>, <a href="https://publications.waset.org/abstracts/search?q=Rotem%20Manor"> Rotem Manor</a>, <a href="https://publications.waset.org/abstracts/search?q=Alfred%20M.%20Bruckstein"> Alfred M.

The agents act in the plane and are identical and indistinguishable, oblivious, and lack any means of direct communication. They do not have a common frame of reference in the plane and choose their orientation (direction of possible motion) at random. The analysis of the gathering process assumes that the agents act synchronously in selecting random orientations that remain fixed during each unit time-interval. Two algorithms are discussed. The first one assumes discrete jumps based on the sensing results given the randomly selected motion direction, and in this case, extensive experimental results exhibit probabilistic clustering into a circular region with radius equal to the step-size in time proportional to the number of agents. The second algorithm assumes agents with continuous sensing and motion, and in this case, we can prove gathering into a very small circular region in finite expected time. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=control" title="control">control</a>, <a href="https://publications.waset.org/abstracts/search?q=decentralized" title=" decentralized"> decentralized</a>, <a href="https://publications.waset.org/abstracts/search?q=gathering" title=" gathering"> gathering</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-agent" title=" multi-agent"> multi-agent</a>, <a href="https://publications.waset.org/abstracts/search?q=simple%20sensors" title=" simple sensors"> simple sensors</a> </p> <a href="https://publications.waset.org/abstracts/115199/probabilistic-gathering-of-agents-with-simple-sensors-distributed-algorithm-for-aggregation-of-robots-equipped-with-binary-on-board-detectors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/115199.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">164</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">2352</span> Cryptography Over Sextic Extension with Cubic Subfield</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Chillali">A.

For this purpose, total 21 players were included, which consist of football players (n=12) and basketball players (n=9), within the age range of 17–20. After receiving the age, length, body weight, vertical jump, and BMI measurements of all subjects, the measurement of lower extremity knee-joint movement (Flexion-Extension) was made with isokinetic dynamometer (isomed 2000) at 60 o/sec. and 240 o/sec. angular velocity. After arrangement and grouping of collected information forms and knee flexion and extension parameters, all data were analyzed with SPSS for Windows. Descriptive analyses of the parameters were made. Non-parametric t test and Mann-Whitney U test were used to compare the parameters of football players and basketball players and to find the inter-group differences. The comparisons and relations in the range p<0.05 and p<0.01 between the groups were surveyed. As a conclusion, no statistical differences were found between isokinetic knee flexion and extension parameters of football and basketball players. However, it was found that the football players were older than the basketball players. In addition to this, the average values of the basketball players in the highest torque and the highest torque average curve were found higher than football players in comparisons of left knee extension. However, it was found that fat levels of the basketball players were found to be higher than the football players. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=isokinetic%20contraction" title="isokinetic contraction">isokinetic contraction</a>, <a href="https://publications.waset.org/abstracts/search?q=isokinetic%20dynamometer" title=" isokinetic dynamometer"> isokinetic dynamometer</a>, <a href="https://publications.waset.org/abstracts/search?q=peak%20torque" title=" peak torque"> peak torque</a>, <a href="https://publications.waset.org/abstracts/search?q=flexion" title=" flexion"> flexion</a>, <a href="https://publications.waset.org/abstracts/search?q=extension" title=" extension"> extension</a>, <a href="https://publications.waset.org/abstracts/search?q=football" title=" football"> football</a>, <a href="https://publications.waset.org/abstracts/search?q=basketball" title=" basketball"> basketball</a> </p> <a href="https://publications.waset.org/abstracts/18790/comparison-of-isokinetic-powers-flexion-and-knee-extension-of-basketball-and-football-players-age-17-20" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18790.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">530</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">2350</span> Stem Covers of Leibniz n-Algebras</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nat%C3%A1lia%20Maria%20Rego">Natália Maria Rego</a> </p> <p class="card-text"><strong>Abstract:</strong></p> ALeibnizn-algebraGis aK-vector space endowed whit a n-linearbracket operation [-,…-] : GG … G→ Gsatisfying the fundamental identity, which can be expressed saying that the right multiplication map Ry2, …, ᵧₙ: Gn→ G, Rᵧ₂, …, ᵧₙn(ˣ¹, …, ₓₙ) = [[ˣ¹, …, ₓₙ], ᵧ₂, …, ᵧₙ], is a derivation. This structure, together with its skew-symmetric version, named as Lie n-algebra or Filippov algebra, arose in the setting of Nambumechanics, an n-ary generalization of the Hamiltonian mechanics. Thefirst goal of this work is to provide a characterization of various classes of central extensions of Leibniz n-algebras in terms of homological properties. Namely, Commutator extension, Quasi-commutator extension, Stem extension, and Stem cover. These kind of central extensions are characterized by means of the character of the map *(E): nHL1(G) → M provided by the five-term exact sequence in homology with trivial coefficients of Leibniz n-algebras associated to an extension E : 0 → M → K → G → 0. For a free presentation 0 →R→ F →G→ 0of a Leibniz n-algebra G,the term M(G) = (R[F,…n.., F])/[R, F,..n-1..,F] is called the Schur multiplier of G, which is a Baer invariant, i.e., it does not depend on the chosen free presentation, and it is isomorphic to the first Leibniz n-algebras homology with trivial coefficients of G. A central extension of Leibniz n-algebras is a short exact sequenceE : 0 →M→K→G→ 0such that [M, K,.. ⁿ⁻¹.., K]=0. It is said to be a stem extension if M⊆[G, .. n.., G]. Additionally, if the induced map M(K) → M(G) is the zero map, then the stem extension Eis said to be a stem cover. The second aim of this work is to analyze the interplay between stem covers of Leibniz n-algebras and the Schur multiplier. Concretely, in the case of finite-dimensional Leibniz n-algebras, we show the existence of coverings, and we prove that all stem covers with finite-dimensional Schur multiplier are isoclinic. Additionally, we characterize stem covers of perfect Leibniz n-algebras. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=leibniz%20n-algebras" title="leibniz n-algebras">leibniz n-algebras</a>, <a href="https://publications.waset.org/abstracts/search?q=central%20extensions" title=" central extensions"> central extensions</a>, <a href="https://publications.waset.org/abstracts/search?q=Schur%20multiplier" title=" Schur multiplier"> Schur multiplier</a>, <a href="https://publications.waset.org/abstracts/search?q=stem%20cover" title=" stem cover"> stem cover</a> </p> <a href="https://publications.waset.org/abstracts/140090/stem-covers-of-leibniz-n-algebras" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/140090.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">157</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">2349</span> Public and Private Involvement in Agricultural Extension Services: Factors of Farmers’ Preference in Southwestern Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20O.%20Ayansina">S.

The study was therefore designed to examine the farmers’ preference for public and private extension services in Southwestern Nigeria, specifically to determine the farmers’ level of participation in the two types of organizations involved and also to evaluate the Performance level of personnel in the two organizations in order to ascertain the beneficiaries’ satisfaction. A multi-stage random sampling technique was used to samples 30 respondents from each of the three selected organizations in each of the three states sampled in Southwestern Nigeria. Hence, 270 respondents were sampled for the study. Data collected were analyzed with Kruskal Wallis one-way Analysis of variance to test the difference between the participation of beneficiaries in the public and private extension services and the level of benefit accrued from the two organizations involved in the study. Results generally revealed that private organizations were performing better and were more preferred by the beneficiaries. Results of the tested hypotheses as shown by Kruskal Wallis test of difference (x2=0.709) indicates no significant difference between farmers’ participation in the extension services of public and private organizations but however shows significant difference (X2=12.074) in the benefits achieved by respondents in the two organizations, such benefits include: increased quantity of Crop produced, farm income, skill acquisition, and improved Education in private extension organizations. Based on this result, it could be inferred that beneficiaries generally preferred private extension organizations because of their effectiveness and vibrancy in programme administration. Public extension is therefore recommended for general overhauling and possibly “merging” of public and private sectors in order to cater for teeming population of farmers demanding for efficient and functional extension services to better their lots both in production and processing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=public%20and%20private%20involvement" title="public and private involvement">public and private involvement</a>, <a href="https://publications.waset.org/abstracts/search?q=extension%20services" title=" extension services"> extension services</a>, <a href="https://publications.waset.org/abstracts/search?q=farmers%E2%80%99%20preferences" title=" farmers’ preferences"> farmers’ preferences</a>, <a href="https://publications.waset.org/abstracts/search?q=Kruskal%20Wallis%20Test" title=" Kruskal Wallis Test"> Kruskal Wallis Test</a> </p> <a href="https://publications.waset.org/abstracts/3944/public-and-private-involvement-in-agricultural-extension-services-factors-of-farmers-preference-in-southwestern-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3944.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">332</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">2348</span> From Modern to Contemporary Art: Transformations of Art Market in Istanbul</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cem%20Ozatalay">Cem Ozatalay</a>, <a href="https://publications.waset.org/abstracts/search?q=Senem%20Ornek"> Senem Ornek</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Artprice Contemporary Art Market Annual Report 2014 notices that Istanbul, with its art market volume of $3.6 million has become the first city of the Middle East and North Africa region and the 14th city of the World. Indeed, the period 2004–2014 has been significant in terms of the growth of the art market, during which the majority of contemporary art galleries and museums in Istanbul was inaugurated. This boom means that with the joining of new agents, the structure of the art market has dramatically changed. To use Nathalie Heinich’s terminology, in the current art field, three art genres – namely classical art, modern art and contemporary art – coexist, but in the case of Istanbul, such as many art cities in the world, the latter genre has become increasingly dominant. This presentation aims to show how the power shifts away from the classical art agents to contemporary art agents, and the effects produced by the conflicts between the old and new agents of current art field. Based on the data obtained from an ongoing field research in Istanbul among the art market agents such as art dealers, curators, art critics and artists, it will be shown that even if the agents of different art genres are in conflict with each other, there is, at the same time, a continuum between the three art worlds. <p class="card-text"><strong>Keywords:</strong> <a
