An Induction motor reliability survey at an egg processing plant shows that almost 50% of the total motor failures are fan induction motors. Visual investigations of the faulty fan motors show that the main cause of the induction motor failure is air gap eccentricity. In this study, experimental tests are performed on a 1.1kW three-phase induction motor to detect air gap eccentricity and overheating of the induction motor. Heating tests show that end shield housing temperature reaches 100°C with blocked air flow from the fan, which can reduce the lifespan of the bearing. Dimension measurements of the end shield housing show that the dimensions of both tested motors back-end shields are larger than ISO tolerance grade limit. It leads to a loose fit between the housing and bearing, causing air gap eccentricity. Also, both motor back end shield housing has an out-of-round condition leading to an unbalanced magnetic pull. To detect the air gap eccentricity caused by too loose of a fit between housing bore and bearing, current Park’s vector approach is used. To measure three phase current, Hall Effect current transducers, a digital oscilloscope is used and Matlab software to process the measurement data. Results show that Park’s vector approach can be used to detect the air gap eccentricity caused by too loose a fit between bearing and housing. Therefore, the Park’s vector approach can be used to diagnose air gap eccentricity and analyse the type of the air gap eccentricity.

Climate change and environmental deterioration have been recognized as global drivers of change, and the shift to the “greener” economy is the key to sustainable development. The green economy is a priority field for developing and developed economies. However, as the authors of the publication have realised, there is no consensus about the meaning of the green economy and “green” jobs, that is why an uncertainty as in measurement of economic trends and an impact of it, as well as in what skills and competencies should be assigned to the “green” ones, arises. The new “green” processes and technologies are arising in a progressive trend, that is why it is important to ensure there are properly skilled candidates with appropriate “green” skills and competencies on the labour market, as well as to prepare fresh graduates with the “green” skills that will meet requirement of both, the recent and the future companies, especially operating in the “green” sector. In the framework of “SB Bridge” project an online survey was conducted by interviewing the “green” companies to identify which skills and competencies are needed for “green” jobs recently, and whether candidates and fresh graduates are enough with the “green” skills and competencies for fruitful engagement to “green” jobs. As the survey identified, fresh graduates and candidates for “green” jobs lack technical and (or) mechanical knowledge, IT skills, as well as experience and ability to work independently and in the team to resolve arising problems.

Information and communication technologies are part of almost any branch of human lives. During the last decade also beekeeping joined the direction of application of IT tools and solutions and precision beekeeping was defined. Still in the beekeeping many operations and observations are completed manually, and there is a potential to switch to the digital realisation. Information technologies can be used in the beekeeping to partly support the beekeepers by implementation of automatic or semi-automatic solutions for bee colony remote monitoring, apiary record making and other actions. The aim of this paper is to make a summary of the usage of information technology tools by the beekeepers in Latvia, summarizing precision beekeeping development status and conclude about its future development potential. To achieve this aim, in cooperation with Latvian Beekeepers Association, a beekeepers survey was conducted. More than 200 beekeepers shared thoughts and opinions about their application of information and communication technologies for monitoring the bee colonies and apiary management. The summary of the survey conducted is described in this study.

A relevant and practical research object is analysed in the article – the implementation resolution of green transportation and the benefits of using such means. In this article, object is analysed from the interdisciplinary position, i.e. from the perspective of transportation, one of the logistical subsystems, and sustainable environment. The transportation department is undoubtedly an important guarantor of economic and industrial development. Despite the worldwide importance of transportation in everyday activities, the transportation also poses the risk for human health and life quality, for it is one of the biggest consumer of oil products and significantly contributes towards air pollution. Despite many theoretical and empirical researches, Šiauliai region still lacks an approach towards the implementation possibilities and studies revealing the benefits of green transportation. A comparative analysis has been performed by using the survey data, collected from 402 workers, responsible for transportation, working for Šiauliai regional companies. According to the results of the research for implementation situations of green transport in Šiauliai regional companies, the representatives of regional companies understand the importance of green transport, and more and more companies aim to reduce the environmental risk and to become more competitive. Integrated transportation by combining several means of transport, cargo consolidation by combining small orders and big orders, and ecological driving are the green transportation measures implemented most in regional companies. The typical benefits of green transport are increased environmental friendliness and improved relationship with consumers.

In sub-Saharan Africa intensifying small-scale farming is essential in addressing poverty related issues in rural communities and the degradation of natural resources. Integrated Soil Fertility Management (ISFM) are the best practices used to improve the productivity of crops whilst maximizing agronomic efficiency of inputs applied and hence contributing to sustainable intensification. ISFM usually include the appropriate use of inorganic fertilizer and organic resources, good agronomic practices and appropriate use of germplasm. The survey was carried-out on the awareness of Integrated Soil Fertility Management practices in the Savelugu Municipal of Northern Ghana to study the awareness of integrated soil fertility management practices amongst farmers through the administration of questionnaires. A multistage method of sampling was used in selecting thirty (30) respondents randomly from five (5) selected communities namely Jana, Yapalsi, Diari, Nabogu and Gushie to make up a total sample size of 150 respondents. Frequency distribution and percentages were used to represent the data. Correlation analysis was used to test for the relationship between awareness, educational level and household size. The survey showed that majority of the respondents at ages between 21 and 30 years were married and majority with household size of 3 to 5 as well as primary and secondary education. Farming activities were carried-out by hand (80%). Majority of the respondents (43.3%) were informed about ISFM through demonstrations and 20% of the farmers apply inorganic fertilizer. About 85.5% of the respondents were aware of ISFM. The research also revealed that ISFM improves production and supports finances of respondents. The assessment of respondents’ perception of ISFM revealed a positive agreement of the effect of ISFM on soil health as well as improved production. In conclusion, it is thus suggested that it is needful for the involvement of the government on the adoption of ISFM via Non-Governmental Organisations (NGOs) locally and or internationally for a suitable advancement and to guarantee a sustainable environment with a world-wide corporation for improvement.

The constructivist approach is based on the idea that knowledge can never be passed from one person to another. The only way to acquire knowledge is to create or construct them. The constructivist approach changes also the role of the teacher in the educational process, the task of them is to organize the environment so that the student himself can construct the cognitive forms that teacher wants to give him. In the paper, the nature of the constructivist approach is identified, different aspects regarding mathematics education are analysed as well as the potential impact on the development of mathematical competences in the context of sustainable development is discussed. The study process and learning methods appropriate to constructivist approach also were studied. In order to illustrate the need for a constructivist approach in mathematics education, the survey of students from Latvia University of Life Science and Technologies (LLU) and Riga Technical University (RTU) were carried out, the results of which proved that mathematics learning at universities has to be changed. The current study proved that the constructivist approach radically changes the process of teaching and learning mathematics, connecting it with daily life, rather than teaching only abstract formulas and using a creative approach to mathematical tasks solving. This study shows that using constructivist approach to the teaching of mathematics, the competences needed for sustainable development are boosted.

Climate change is an inevitable global challenge of the 21st century. For developing countries like Ethiopia, it intensifies existing challenges towards ensuring sustainable development. Adopting the protection motivation theory, this study examined factors affecting the practice of climate change adaptation and mitigation strategies among farmers. The study employed a mixed research approach to assess the subjective understanding of farmers about climate change threats and identify factors determining their responses to climate change effects. Qualitative data were collected using focus group discussions and interviews. Quantitative information was gathered using semi-structured survey from 296 randomly selected farmers. Qualitative data was dominantly analysed using content analysis, while descriptive and inferential statistics were applied to analyse quantitative data. Almost all respondents (97%) perceived that climate change was occurring and threatening their wellbeing. Dwindling precipitation, increasing temperature and occurrence of human and animal disease were perceived to represent climate change effects. From nationally initiated strategies, farmers were found to largely practice soil and water conservation, which they perceived as less costly and compatible to local knowledge. The result of binary logistic regression revealed that perceived severity of climate change, perceived susceptibility to climate change threat, perceived own ability to respond, response efficacy, and cost of practices predicted farmers’ motivation to practice climate change adaptation and mitigation strategies. Thus, building a resilient system should go beyond sensitizing climate response mechanisms. Policies should focus on human capital development and economic empowerment which would enable farmers to pursue context-specific adaptation and mitigation strategies, thereby maintaining a sustainable livelihood.

In rural Kazakhstan, the credit and insurance services are limited and the state support is weak. The main goal of this study is to contribute to the literature on financial literacy in emerging economies, namely, the effect of financial literacy on saving rates of rural population. Being well educated not always means to be financial literate and make efficient decisions regarding one’s own finance. People with a lower formal education level but with better experience in consuming financial products could be better prepared for making financial decisions including those related to savings. In this paper other socio-economic determinants of saving rates were taken into account, such as an income level, family size and an employment status. This research was carried out in Pavlodar region of Kazakhstan, and the data collection took place in spring 2014. In total, 405 households were surveyed. Results of the analysis show that if a respondent gives at least one correct answer, it positively affects the saving rates as well as one can observe that the higher the financial literacy level, the higher are the saving rates. Availability of state supported financial education programs for rural people will significantly contribute to the financial literacy improvement.

This research in progress paper investigates the multifaceted factors shaping the work-related attitudes of top managers in organizations with a focus on Germany. Through in-depth interviews with seasoned experts, it reveals crucial work attitudes, examines the impact of interpersonal and procedural factors, and evaluates information’s role in the principal-agent relationship at top management levels. The findings challenge conventional assumptions, providing different perspectives on leadership and highlighting the evolving nature of management practices in the digital age. The study also explores potential differences between top IT managers and other C-level roles, investigating their implications. The results of this research based on expert interviews are used in a broader context of research to triangulate literature analysis findings and quantitative surveys in order to develop a comprehensive understanding of factors influencing top managers’ work attitudes. Semi-structured expert interviews were conducted to gain a comprehensive perspective on the influencing factors of work attitudes in top management functions. Six German experts participated, bringing diverse backgrounds and affiliations with professional associations. Despite varied perspectives, universal importance was identified in key work attitudes, challenging assumptions of significant differences between employer and employee representatives. A novel contrast between hierarchical and broader perspectives within owner and worker associations emerged, suggesting a need for a more comprehensive understanding of management approaches. Additionally, interpersonal factors in leadership, information flow, trust-building, were highlighted as contributions. Furthermore, distinctions and commonalities between IT management and other top managerial roles were identified. This study both confirms existing knowledge and introduces valuable insights to management science, potentially shaping future research and practices.

A series of initiatives have been adopted in the European Union to address greenhouse gas emissions and establish a society that is resilient to climate change. In response to these initiatives, the implementation of mobility budgets offers a more precise strategy for addressing carbon footprints associated with travel. Prioritizing localized carbon footprint control, mobility budgets are calculated and customized according to distinct regions, goals, and target demographics. When prioritizing the mobility budget as the central objective in municipal transport route planning, the focus should encompass principles of fairness and equity in travel. This entails considering factors such as accessibility, variety of mobility choices, inclusivity of transportation modes, and social justice. Therefore, this article aims to formulate an enhanced activity modelling methodology that would aid data-driven decision-making in municipal transport route planning, while upholding the principles of travel fairness and equity. Тhe results obtained from scrutinizing data related to public bus services and mobile networks are presented. The evaluation of Jelgava’s city transportation network to facilitate mobility budget reduction is undertaken, and this assessment is based on an analysis of data derived from a survey on public transport use coupled with an examination of the city’s mobility budget. The research presents the communication challenges that municipalities will face in planning and implementing changes that are needed to meet the greenhouse gas emission targets and outlines the possible use of visualization tools for modelling, explanation and communication of scenarios.
