    У даній статті представлені результати аналізу режимів енергоспоживання комплексу некогерентного розсіяння Інституту іоносфери НАН і МОН України з метою вирішення проблеми підвищення енергоефективності науково-дослідного комплексу та створення енергоефективної системи електропостачання, яка забезпечить стійку роботу наукового обладнання для виконання дослідницьких програм НАН України. Описана система електроживлення комплексу та режими енергоспоживання комплексу. Описано пристрої радарної системи, а також найбільш потужні споживачі електроенергії, які споживають електроенергію на експериментальні і господарські потреби. Проаналізовано енергоспоживання комплексу некогерентного розсіяння за 2013 р. Отримано і представлено графіки середньої споживаної потужності (середньодобовий показник) і середньої споживаної потужності в режимі вимірювань. Описана доцільність проведення робіт з оптимізації енергопостачання науково-дослідного комплексу Інституту іоносфери. Запропоновано можливі заходи для зниження економічної вартості проведення експериментів з дослідження іоносфери науково-дослідного комплексу некогерентного розсіяння. Проведено аналіз робіт сучасних авторів з метою показати, що підвищення ефективності функціонування систем електропостачання є актуальною проблемою сучасних досліджень.This article presents the results of the analysis of the energy consumption modes of the incoherent scattering complex of the Institute of Ionosphere of the National Academy of Sciences and the Ministry of Education and Science of Ukraine to solve the problem of increasing the energy efficiency of a research complex and creating an energy efficient power supply system that will ensure the sustainability of scientific equipment for research programs of the National Academy of Sciences of Ukraine. The system of power supply of the complex and modes of power consumption of the complex are described. The devices of the radar system are described, as well as the most powerful consumers of electricity, which consume electricity for experimental and economic needs. The energy consumption of the incoherent scattering complex in 2013 is analyzed. Graphs of the average power consumption (daily average) and average power consumption in measurement modes were obtained and presented. The feasibility of work to optimize the energy supply of the research complex of the institute of the ionosphere is described. Possible measures are proposed to reduce the economic cost of conducting experiments on the study of the ionosphere of an incoherent scattering research complex. The analysis of the works of modern authors i s carried out in order to show that increasing the efficiency of the power supply systems is an actual problem of modern research

    What is it worth?:An empirical investigation into attitudes towards education amongst youngsters following secondary education in Flanders

    This paper argues that whereas the social relevance of attitudes towards education is commonly confined to their direct impact on educational aspirations or attainment, attitudes may also impact on educational success in a way similar to cultural capital. Survey data were used to assess the support for three different attitudes with respect to the perceived value of attending school among youngsters (n = 853) following secondary education in Flanders (the Dutch-speaking part of Belgium). The results revealed substantial differences according to the pupils’ cultural capital, time perspective, personal educational experiences and social mobility. These findings are taken as a starting point for a broader discussion about how attention to attitudes may enable us to account for the power struggles in which the educational field and the teaching profession are involved

    Biosafety in laboratory animal facilities

    In Belgium, most activities involving animal experiments with transgenic and experimentally infected animals are subject to notification in the framework of regional legislation on contained use of genetically modified organisms (GMOs) and/or pathogens. Animal facilities should comply with the containmentcriteria and other protective measures defined in this legislation in order to guarantee optimal protection of public health, the animals and the environment.This paper addresses various concerns on facility design, biosafety equipment, personal protection, working practices and waste management. Quality aspects of animal care falling under laboratory animal welfare regulations are not considered here.</p

    First-generation college students’ motives to start university education: An investment in self- development, one’s economic prospects or to become a role model?

    In this article, we engage with the emerging literature that studies the increased enrolment of first-generation college students (FGCS), that is, students from households where neither parent has obtained a bachelor’s /master’s degree. Our article answers two research questions. First, data from 2,338 first-year students are used to investigate the extent to which FGCS differ from continuing-generation college students (CGCS) concerning the reason why one enrols in university education. Second, to what degree do these motives explain differences in study choice? Our results show that FCGS, compared to CGCS, more strongly endorsed the economic investment motive and what we call the social investment motive, that is, the motivation to become a role model for one’s community. In addition, our findings reveal that the choice for more economically rewarding fields of study is related to these motives to start a university education. In the conclusion, we discuss the implications of our findings
