A Study of Students’ Preferences in The Information Resources of The Digital Learning Environment

The digital learning environment comprises various resources - didactically transformed and untransformed information, and mediated communication. Students’ information behaviour combines both actions characteristic of the traditional educational process and specific for the digital environment, based on digital tools and user interactions. Students’ information behaviour in the digital environment is considered as an indicator of their engagement in various educational activities that contribute to the personalisation of learning. The results of a survey on students’ preferences of information resources in the digital environment show that learners use a variety of information sources, but they mainly apply the methods of work in the “traditional” learning paradigm. They insufficiently use the digital environment potential of collaboration, knowledge exchange, and knowledge extraction from authentic sources. Obtained data indicates problems in students’ information culture and shortcomings in the methodological support of students’ autonomous work. Based on the results, recommendations on creating conditions for developing students’ prospective strategies of interaction with digital resources are proposed. These recommendations include a gradual increase of the authentic digital learning resources, an account of students’ information preferences, and a particular attention to the management issues in the digital learning environment

SOURCES OF UNCERTAINTY AND PROBLEMS OF INCREASING THE ACCURACY OF FLOW ASSESMENT FOR THE TRANSBOUNDARY NARVA RIVER

The water regime of the transboundary Narva River has always been constantly addressed by the hydrometeorological community. For many years, at the interstate level (the Russian Federation and the Republic of Estonia), there has been a discussion about the accuracy of flow assessment and the correctness of the methods applicable for these purposes. In some years, the discrepancies between the estimates of the average annual water discharge obtained by the Estonian and Russian sides reach values of 20-27%. Sustainable, reliable water use requires updating approaches and achieving greater unambiguity in the flow assessment. In the presented article, various sources of uncertainty in the Narva river flow assessment as hydrodynamic, seasonal factors and imperfection of existing methods are considered.

Information environment of blended learning: aspects of teaching and quality

The data from a comparative analysis of regulations in the field of e-learning in some countries participating in the project is represented. The article substantiates indicators of virtual educational invironment in accordance with European standard of quality in higher education. The psychodidactic approach based on accounting of general concepts: information, communication and interaction management in a network learning environment used for evaluation of teaching activities in blended learning. The study hypothesis is based on the data obtained from analysis of the students' views and attitudes towards various educational processes in digital learning environment and represents a set of conditions for system formation of university virtual educational environment and the effective use of e-learning technologies. At a later stage of research teachers in all the universities involved in project will be surveyed

Стратегии информационного поведения студентов в условиях непрерывного образования

Research objective. The research objective was to identify and analyse the general trends, manifested in the information behaviour of students in terms of realising and taking advantage of lifelong learning in the digital society. The authors attempted to answer the question: What is the specificity of modern students’ information behaviour strategies? Materials and methods. The research was based on the concept of “information behaviour”, considered by the authors as a system of actions to implement the processes of interaction with the information environment. In the conditions of digital society development, the effectiveness of information strategies largely depends on the adoption of the values of lifelong learning. In the context of the activity approach, information behaviour includes the motivational aspect (acceptance of the lifelong learning paradigm, motives of educational activity, relations, interests and orientations within the current learning stage) and the activity aspect (general learning strategies, approaches to new information acquisition, self-management strategies in the learning process, as well as the possession of modern tools to implement these strategies – ICT tools). The research methods included a survey and statistical analysis. During the survey, Russian and Polish students were asked to relate the degree of information behaviour characteristics to a five-point scale. Statistical analysis comprised descriptive statistics, including the distribution of answers for all respondents, comparative statistics for Polish and Russian students, and correlation analysis. Results of the study. The research results have showed that students understand the importance of lifelong learning and accept it as a value and requirement of the 21st century. However, their information behaviour is not always based on effective strategies. Educational activity is insufficiently supported by the use of ICT tools for self-management, goal setting, and construction of an individual educational route. Direct correlations were revealed between the readiness for lifelong learning and the development of initiative, responsibility, self-management, including the active use of specialised electronic tools. Information behaviour is associated with future professional activities. For example, for socially oriented professions, information behaviour comprises such features as openness and empathy. Conclusion. Based on the results obtained, recommendations for lecturers can be formulated to support the process of mastering the advanced strategies of information behaviour by students. Firstly, it is necessary to encourage students to use open electronic resources, not only to access the newest information, but to join the processes of qualitatively new knowledge creation in collaborate work (self-directed learning, learning in partnership, collaborative learning). Secondly, it is important to create conditions for the expansion of professional experience through the strengthening of the practice-oriented assignments role, as well as the inclusion of students in project, competitive and grant activities

Economic Mechanisms of Management of Socio-Ecological Systems’ Sustainability

The purpose of the article is to develop perspective economic mechanisms of management of socio-ecological systems’ sustainability. In order to achieve this goal, the authors use the method of correlation and regression analysis, scenario analysis, method of modeling and forecasting, as well as methods of systemic and problem analysis, synthesis, induction, deduction, and graphic and table representation of information. In the process of the research, the authors determine the essence of socio-ecological systems’ sustainability, study the contradiction of interests of society’s development and protection of the environment. For realization of the set tasks, the authors determine the current state of socio-ecological systems from the point of view of balance of these interests and analyze the connection between economic and ecological indicators of the countries’ development. A tool for confirming the offered hypothesis is calculation of correlation of ecological effectiveness index and gross internal products. As a result of the research, the authors come to the conclusion that economic reasons are the main ones for emergence and aggravation of the problem of harmonic and sustainable development of socio-ecological systems; thus, economic tools are required for solving this problem. The authors offer perspective mechanisms of management of sustainability of modern socio-ecological systems and view scenarios of future development of events in the sphere of management of sustainability of socio-ecological systems

Evaluating the Epidemic Risk Posed by Marek's Disease Virus in Russia

Background: The highly oncogenic avian alpha herpes virus known as Marek's disease virus (MDV) raises concerns about its potential oncogenicity in humans. In this article, authors examine the potential epidemic risks associated with MDV, taking into account the current epidemic and epizootic situation in the Russian Federation, with a particular focus on the modern practices of pig and poultry farming. Given its oncogenic properties, MDV remains a cause for concern in the field of avian herpesviruses.Methods: The study was conducted in 2010-2022 in poultry farms Russian Federation, Republic of Belarus and the Republic of Kazakhstan where authors monitored the rate of vesicular enteritis and MDV. In total, 155 epizootics were examined, including the analysis of 62 epizootics of vesicular enteritis and the population of the studied area exceeded 1 million people.Results: The authors of the study found that vesicular enteritis, distributed over poultry farms in the Russia since 2011, and its safety for the population remains unknown. The increasing incidence of vesicular enteritis was also accompanied by various health issues in contact persons and veterinary personnel, as well as abnormal and in sync increases in infectious laryngotracheitis and MDV in young birds.Conclusion: Authors come to the conclusion that the consequences of COVID-19 are accompanied by a deficiency of folic acid, which in turn leads to a risk of developing diseases associated with DNA viruses.It is concluded that MDV may contribute to the development of reproductive and breast cancers, highlighting the need for increased awareness and attention to the health risks associated with poultry farming and further research in this area.Keywords: Marek's disease virus; Vesicular enteritis; Herpesvirus infection; COVID 19

Dark‑adaptation in the eyes of a lake and a sea population of opossum shrimp (Mysis relicta): retinoid isomer dynamics, rhodopsin regeneration, and recovery of light sensitivity

We have studied dark-adaptation at three levels in the eyes of the crustaceanMysis relictaover 2-3 weeks after exposing initially dark-adapted animals to strong white light: regeneration of 11-cisretinal through the retinoid cycle (by HPLC), restoration of native rhodopsin in photoreceptor membranes (by MSP), and recovery of eye photosensitivity (by ERG). We compare two model populations ("Sea", S-p, and "Lake", L-p) inhabiting, respectively, a low light and an extremely dark environment. 11-cisretinal reached 60-70% of the pre-exposure levels after 2 weeks in darkness in both populations. The only significant L-p/S(p)difference in the retinoid cycle was that L(p)had much higher levels of retinol, both basal and light-released. In S-p, rhodopsin restoration and eye photoresponse recovery parallelled 11-cisretinal regeneration. In L-p, however, even after 3 weeks only ca. 25% of the rhabdoms studied had incorporated new rhodopsin, and eye photosensitivity showed only incipient recovery from severe depression. The absorbance spectra of the majority of the L(p)rhabdoms stayed constant around 490-500 nm, consistent with metarhodopsin II dominance. We conclude that sensitivity recovery of S(p)eyes was rate-limited by the regeneration of 11-cisretinal, whilst that of L(p)eyes was limited by inertia in photoreceptor membrane turnover.Peer reviewe
