Multistage sampling procedures were used to randomly select 66 crop farmers in the study area. Data were collected by means of a structured questionnaire. The result was analyzed using descriptive and inferential statistics. Results showed that the majority of the respondents were males with a mean age of 39 years and a farming experience of 16 years. About 95% of the respondents had formal education, with a mean household size of 8 persons per household. Farmer-herder conflicts were found to be caused by grazing on growing crops, wrong approach by farmers in raising complaints and harassment of herdsmen, absence of grazing route and poisoning of uncultivated lands. Constraints to resolving conflict were found to include personal interest, lack of government will, ethnicity and religious difference and open grazing ranking first, second and third, among others. Six factors connected to farmer-herder conflict were found to significantly affect the livelihood of rural households. These were the value of crops destroyed, the number of livestock lost, and the cost of treatment of wounds sustained from the conflict. The value of crops and the size of farmland abandoned in fear were significant, and the cost of seeking redress was significant at P≤0.01. It was concluded that farmer-herder conflict impacts negatively not only crops and animals but also affects the lives of farmers and herders as well as their economy. It is recommended that proper methods be adopted to avoid its occurrence, and when it occurs, the erring party should be appropriately punished. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=farmer" title="farmer">farmer</a>, <a href="https://publications.waset.org/abstracts/search?q=herder" title=" herder"> herder</a>, <a href="https://publications.waset.org/abstracts/search?q=conflict" title=" conflict"> conflict</a>, <a href="https://publications.waset.org/abstracts/search?q=effect" title=" effect"> effect</a>, <a href="https://publications.waset.org/abstracts/search?q=coping" title=" coping"> coping</a> </p> <a href="https://publications.waset.org/abstracts/187177/assessment-of-the-effect-of-farmer-herder-conflict-on-the-livelihood-of-rural-households-in-bogoro-local-government-area-of-bauchi-state-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/187177.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">43</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">8</span> Introduction of a Model of Students' Practice in Social Work Education: Case of Republic of Srpska</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vesna%20%C5%A0u%C4%87ur-Janjetovi%C4%87">Vesna Šućur-Janjetović</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrea%20Rakanovi%C4%87%20Radonji%C4%87"> Andrea Rakanović Radonjić</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Department of Social Work of the Faculty of Political Sciences, University of Banja Luka is the only School of Social Work in the Republic of Srpska (entity of Bosnia and Herzegovina). This Department has been implementing students’ practice as mandatory module since it was established in year 2000. As of 2006, the University of Banja Luka initiated the transformation of the education system in accordance with the Bologna Agreement. The Department of Social Work adopted a new Curriculum that anticipated 120 hours of Students’ practice. After ten years, a new process of changing and improving the Curriculum has been initiated, and research was conducted, in order to meet both the needs of practice and academic standards in the field of social work education. From 2006-2016 students were evaluating their practice experience under the mentor’s supervision. These evaluations were subject to the evaluation process of current Curriculum, including students practice module. Additional research was designed in order to assess the opinions of certified mentors on specific aspects of students’ practice, the needs of practice and possibilities for improving the education for social workers. Special research instruments were designed for the purpose of this research. All mentors were graduated social works working in all fields where social work services are provided (social welfare sector, health, education, non-government sector etc.). The third dimension of the research was a qualitative analysis of curriculums of Schools of Social Work in the region of Southeast Europe. This paper represents the results of the research, conclusions and consequences that led towards the improvement of Students’ practice and Curriculum of the Department of Social Work. The new Model anticipates 300 hours of Students’ practice, divided in three years of study, with different and specific learning outcomes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=curriculum" title="curriculum">curriculum</a>, <a href="https://publications.waset.org/abstracts/search?q=Republic%20of%20Srpska" title=" Republic of Srpska"> Republic of Srpska</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20work%20education" title=" social work education"> social work education</a>, <a href="https://publications.waset.org/abstracts/search?q=students%E2%80%99%20practice" title=" students’ practice"> students’ practice</a> </p> <a href="https://publications.waset.org/abstracts/68886/introduction-of-a-model-of-students-practice-in-social-work-education-case-of-republic-of-srpska" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68886.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">277</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">7</span> Knowledge and Adoption of Agricultural Biotechnology among Small-Scale Farmers in Taraba State Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20H.%20Paul">A.

Purposive and simple sampling techniques were used to select respondents. Questionnaires were administered to 90 respondents. Data were analyzed using descriptive and inferential statistics. The results showed that the majority (73.3%) of the respondents were small-scale farmers, whereas 24.4 percent were engaged in secondary occupations. The mean farm size was 1-5 ha. The majority (72.2%) had one form of formal education or another. About 84 percent (84.4%) had been farming for at least 10 years. There was a mean household size of 6-10 persons. Many (97.8%) of the respondents were knowledgeable about biotechnology, and about 70.0 percent (70.1%) reported that the biotechnology products which they had adopted were very good for animals and human consumption. The result of Pearson’s correlation (r = 0.699) was significant at the 0.01 alpha level. Therefore, the hypothesis that there is no significant relationship between knowledge and adoption of agricultural biotechnology was rejected. It was concluded that the agricultural biotechnologies that were adopted were very safe for animals, humans, and the environment. It was recommended that the government should employ more extension agents to help educate farmers about agricultural biotechnology. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agricultural" title="agricultural">agricultural</a>, <a href="https://publications.waset.org/abstracts/search?q=adoption" title=" adoption"> adoption</a>, <a href="https://publications.waset.org/abstracts/search?q=biotechnology" title=" biotechnology"> biotechnology</a>, <a href="https://publications.waset.org/abstracts/search?q=knowledge" title=" knowledge"> knowledge</a> </p> <a href="https://publications.waset.org/abstracts/121790/knowledge-and-adoption-of-agricultural-biotechnology-among-small-scale-farmers-in-taraba-state-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/121790.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">138</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">6</span> Interactive and Innovative Environments for Modeling Digital Educational Games and Animations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ida%20Srdi%C4%87">Ida Srdić</a>, <a href="https://publications.waset.org/abstracts/search?q=Luka%20Mandi%C4%87"> Luka Mandić</a>, <a href="https://publications.waset.org/abstracts/search?q=LidijaMandi%C4%87"> LidijaMandić</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Digitization and intensive use of tablets, smartphones, the internet, mobile, and web applications have massively disrupted our habits, and the way audiences (especially youth) consume content. To introduce educational content in games and animations, and at the same time to keep it interesting and compelling for kids, is a challenge. In our work, we are comparing the different possibilities and potentials that digital games could provide to successfully mitigate direct connection with education. We analyze the main directions and educational methods in game-based learning and the possibilities of interactive modeling through questionnaires for user experience and requirements. A pre and post-quantitative survey will be conducted in order to measure levels of objective knowledge as well as the games perception. This approach enables quantitative and objective evaluation of the impact the game has on participants. Also, we will discuss the main barriers to the use of games in education and how games can be best used for learning. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bloom%E2%80%99s%20taxonomy" title="Bloom’s taxonomy">Bloom’s taxonomy</a>, <a href="https://publications.waset.org/abstracts/search?q=epistemic%20games" title=" epistemic games"> epistemic games</a>, <a href="https://publications.waset.org/abstracts/search?q=learning%20objectives" title=" learning objectives"> learning objectives</a>, <a href="https://publications.waset.org/abstracts/search?q=virtual%20learning%20environments" title=" virtual learning environments"> virtual learning environments</a> </p> <a href="https://publications.waset.org/abstracts/145447/interactive-and-innovative-environments-for-modeling-digital-educational-games-and-animations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/145447.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">98</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">5</span> Processes of Identities Formation and Transformation among Professional Skilled Mexican Migrants in the United States</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Laura%20Vazquez%20Maggio">M.

Following the idea that identities are never singular, multifaceted and have a necessarily processual character, the authors specifically analyze three dimensions of the identity of qualified Mexican migrants in the US and the interplay between them. Drawing on semi-structured interviews with skilled Mexican middle-class migrants in the US, the paper explores how skilled Mexican migrants preserve their ethno-national identity (their ‘Mexicanness’) in reaction to a hostile socio-political reception context in the US. It further shows how these migrants recreate their class identity and show tendencies to distance themselves from what they perceive as lower-class Mexican migrants and the dominant popular Mexican and Latin-American cultural expressions. In a final step, it examines how the lived experience of migration itself impacts the migrants’ identities, their concept of self and feelings/modes of being and belonging. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ethno-national%20identity" title="ethno-national identity">ethno-national identity</a>, <a href="https://publications.waset.org/abstracts/search?q=middle%20class%20identity" title=" middle class identity"> middle class identity</a>, <a href="https://publications.waset.org/abstracts/search?q=middle-class%20migration" title=" middle-class migration"> middle-class migration</a>, <a href="https://publications.waset.org/abstracts/search?q=migrants%E2%80%99%20identity" title=" migrants’ identity"> migrants’ identity</a>, <a href="https://publications.waset.org/abstracts/search?q=skilled%20migration" title=" skilled migration"> skilled migration</a> </p> <a href="https://publications.waset.org/abstracts/123405/processes-of-identities-formation-and-transformation-among-professional-skilled-mexican-migrants-in-the-united-states" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/123405.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">143</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">4</span> Technology, Organizational and Environmental Determinants of Business Intelligence Systems Adoption in Croatian SME: A Case Study of Medium-Sized Enterprise</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ana-Marija%20Stjepi%C4%87">Ana-Marija Stjepić</a>, <a href="https://publications.waset.org/abstracts/search?q=Luka%20Su%C5%A1ac"> Luka Sušac</a>, <a href="https://publications.waset.org/abstracts/search?q=Dalia%20Su%C5%A1a%20Vugec"> Dalia Suša Vugec</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the last few years, examples from scientific literature and business practices show that the adoption of technological innovations increases enterprises' performance. Recently, when it comes to the field of information technology innovation, business intelligence systems (BISs) have drawn a significant amount of attention of the scientific circles. BISs can be understood as a form of technological innovation which can bring certain benefits to the organizations that are adopting it. Therefore, the aim of this paper is twofold: (1) to define determinants of successful BISs adoption in small and medium enterprises and thus contribute to this neglected research area and (2) to present the current state of BISs adoption in small and medium-sized companies. In order to do so, determinants are defined and classified into three dimensions, according to the Technology – Organization – Environment (TOE) theoretical framework that describes the impact of each dimension on technological innovations adoption. Moreover, paper brings a case study presenting the adoption of BISs in practice within an organization from tertiary (service) industry sector. Based on the results of the study, guidelines for more efficient, faster and easier BISs adoption are presented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adoption" title="adoption">adoption</a>, <a href="https://publications.waset.org/abstracts/search?q=business%20intelligence" title=" business intelligence"> business intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=business%20intelligence%20systems" title=" business intelligence systems"> business intelligence systems</a>, <a href="https://publications.waset.org/abstracts/search?q=case%20study" title=" case study"> case study</a>, <a href="https://publications.waset.org/abstracts/search?q=TOE%20framework" title=" TOE framework"> TOE framework</a> </p> <a href="https://publications.waset.org/abstracts/108043/technology-organizational-and-environmental-determinants-of-business-intelligence-systems-adoption-in-croatian-sme-a-case-study-of-medium-sized-enterprise" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108043.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">149</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">3</span> Impact of the Electricity Market Prices during the COVID-19 Pandemic on Energy Storage Operation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marin%20Mandi%C4%87">Marin Mandić</a>, <a href="https://publications.waset.org/abstracts/search?q=Elis%20Sutlovi%C4%87"> Elis Sutlović</a>, <a href="https://publications.waset.org/abstracts/search?q=Ton%C4%87i%20Modri%C4%87"> Tonći Modrić</a>, <a href="https://publications.waset.org/abstracts/search?q=Luka%20Stani%C4%87"> Luka Stanić</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With the restructuring and deregulation of the power system, storage owners, generation companies or private producers can offer their multiple services on various power markets and earn income in different types of markets, such as the day-ahead, real-time, ancillary services market, etc. During the COVID-19 pandemic, electricity prices, as well as ancillary services prices, increased significantly. The optimization of the energy storage operation was performed using a suitable model for simulating the operation of a pumped storage hydropower plant under market conditions. The objective function maximizes the income earned through energy arbitration, regulation-up, regulation-down and spinning reserve services. The optimization technique used for solving the objective function is mixed integer linear programming (MILP). In numerical examples, the pumped storage hydropower plant operation has been optimized considering the already achieved hourly electricity market prices from Nord Pool for the pre-pandemic (2019) and the pandemic (2020 and 2021) years. The impact of the electricity market prices during the COVID-19 pandemic on energy storage operation is shown through the analysis of income, operating hours, reserved capacity and consumed energy for each service.

Ti6Al4V alloys, with their high mechanical properties in relation to weight, can reduce the weight of aircraft structures compared to structures made of steel and aluminium. Currently, conventional processes such as casting and CNC machining are used to obtain the desired structures, resulting in high raw material removal, which in turn leads to higher costs and impacts the environment. Additive manufacturing (AM) offers advantages in terms of weight, lead time, design, and functionality and enables the realisation of alternative geometric shapes with high mechanical properties. However, there are currently technological shortcomings that have led to AM not being approved for structural components with high safety requirements. An assessment of damage tolerance for AM parts is required, and quality control needs to be improved. Pores and other defects cannot be completely avoided at present, but they should be kept to a minimum during manufacture. The mechanical properties of the manufactured parts can be further improved by various treatments. The influence of different treatment methods (heat treatment, CNC milling, electropolishing, chemical polishing) and operating parameters were investigated by scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM/EDX), X-ray diffraction (XRD), electron backscatter diffraction (EBSD) and measurements with a focused ion beam (FIB), taking into account surface roughness, possible anomalies in the chemical composition of the surface and possible cracks. The results of the characterisation of the constructed and treated samples are discussed and presented in this paper. These results were generated within the framework of the 3TANIUM project, which is financed by EU with the contract number 101007830. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ti6Al4V%20alloys" title="Ti6Al4V alloys">Ti6Al4V alloys</a>, <a href="https://publications.waset.org/abstracts/search?q=laser%20powder%20bed%20fusion" title=" laser powder bed fusion"> laser powder bed fusion</a>, <a href="https://publications.waset.org/abstracts/search?q=damage%20tolerance" title=" damage tolerance"> damage tolerance</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20treatment" title=" heat treatment"> heat treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=electropolishing" title=" electropolishing"> electropolishing</a>, <a href="https://publications.waset.org/abstracts/search?q=potential%20cracking" title=" potential cracking"> potential cracking</a> </p> <a href="https://publications.waset.org/abstracts/146535/fabrication-and-characterisation-of-additive-manufactured-ti-6al-4v-parts-by-laser-powder-bed-fusion-technique" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146535.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">85</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">1</span> Mineralogical Study of the Triassic Clay of Maaziz and the Miocene Marl of Akrach in Morocco: Analysis and Evaluating of the Two Geomaterials for the Construction of Ceramic Bricks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sahar%20El%20Kasmi">Sahar El Kasmi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ayoub%20Aziz"> Ayoub Aziz</a>, <a href="https://publications.waset.org/abstracts/search?q=Saadia%20Lharti"> Saadia Lharti</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20El%20Janati"> Mohammed El Janati</a>, <a href="https://publications.waset.org/abstracts/search?q=Boubker%20Boukili"> Boubker Boukili</a>, <a href="https://publications.waset.org/abstracts/search?q=Nacer%20El%20Motawakil"> Nacer El Motawakil</a>, <a href="https://publications.waset.org/abstracts/search?q=Mayom%20Chol%20Luka%20Awan"> Mayom Chol Luka Awan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Two types of geomaterials (Red Triassic clay from the Maaziz region and Yellow Pliocene clay from the Akrach region) were used to create different mixtures for the fabrication of ceramic bricks. This study investigated the influence of the Pliocene clay on the overall composition and mechanical properties of the Triassic clay. The red Triassic clay, sourced from Maaziz, underwent various mechanical processes and treatments to facilitate its transformation into ceramic bricks for construction. The triassic clay was subjected to a drying chamber and a heating chamber at 100°C to remove moisture. Subsequently, the dried clay samples were processed using a Planetary Babs ll Mill to reduce particle size and improve homogeneity. The resulting clay material was sieved, and the fine particles below 100 mm were collected for further analysis. In parallel, the Miocene marl obtained from the Akrach region was fragmented into finer particles and subjected to similar drying, grinding, and sieving procedures as the triassic clay. The two clay samples are then amalgamated and homogenized in different proportions. Precise measurements were taken using a weighing balance, and mixtures of 90%, 80%, and 70% Triassic clay with 10%, 20%, and 30% yellow clay were prepared, respectively. To evaluate the impact of Pliocene marl on the composition, the prepared clay mixtures were spread evenly and treated with a water modifier to enhance plasticity. The clay was then molded using a brick-making machine, and the initial manipulation process was observed. Additional batches were prepared with incremental amounts of Pliocene marl to further investigate its effect on the fracture behavior of the clay, specifically their resistance. The molded clay bricks were subjected to compression tests to measure their strength and resistance to deformation. Additional tests, such as water absorption tests, were also conducted to assess the overall performance of the ceramic bricks fabricated from the different clay mixtures. The results were analyzed to determine the influence of the Pliocene marl on the strength and durability of the Triassic clay bricks. The results indicated that the incorporation of Pliocene clay reduced the fracture of the triassic clay, with a noticeable reduction observed at 10% addition. No fractures were observed when 20% and 30% of yellow clay are added. These findings suggested that yellow clay can enhance the mechanical properties and structural integrity of red clay-based products. <p class="card-text"><strong>Keywords:</strong> <a
