Research of opportunities for the ecosystem approach to career planning by students at the State University of Management

The article presents the results of studying the possibilities of an ecosystem approach to career planning by students at the State University of Management (hereinafter referred to as SUM). At first, the gap between the level of practical training of graduates of Russian universities and the requirements of employers has been actualised. Then, the need for joint efforts of all interested labour market participants to create conditions for students’ conscious planning of career growth at all stages of education is emphasised. The experience of intra-university cooperation using the STC (student team consulting) method between the marketing department and practical training department in 2022–2023 has showed that solving this problem involves integrating, on an ecosystem basis, activities for the study of professional academic disciplines, project-based learning, practical training, and employment. As an experiment, 6 student consulting teams have solved a set of interrelated tasks, including the creation and ongoing maintenance of the Career Centre page in the VK social network, advertising campaigns and interviews at “Career Day in Transport and Logistics”, surveys on the employment of graduates and assessment of student satisfaction with practical training, analytical review of the labour market in Russia in 2020–2023 with a report at the All-Russian scientific and practical conference, examination of 5 ideas for marketing research projects in the field of career planning by students of the SUM with testing in social networks and assessments of the influence of actors in its ecosystem. In conclusion, based on the results of the research, the directions for the ecosystem approach to career planning by students at the SUM are formulated.

Wisdom of age is the main psychological geroprotector in older people (analytical review)

The article presents an analytical review of the problem of aging from the standpoint of social and spiritual forms of human life. The intensive growth in the number of elderly people has sharply reduced the quality of public attitude towards them. The foundations of social relations between elderly people and the state, intergenerational, family, and other relations have acquired a new colouring, in connection with which the importance of wisdom in solving these problems increases. The wisdom in an elderly person is potent of keeping his inner world in a state of balance. A wise person perceives his presence in life as a paradigm of integration, which determines the coexistence of all age phases during his life. It helps to cast aside regret about past failures, unfulfilled hopes, to find a lot of good even in a far from easy life. Wisdom is the universe to which a person should come in old age. Wisdom will always find something that will please and strengthen the spiritual strength of a person, make his life positions stable, lead away from despondency and a sense of helplessness. The wisdom of age creates self-confidence in an elderly person, pride in the years lived with dignity, in the benefits created, which are used by the young. The concept of “conscious aging” is based on inner strength and spiritual stability over old age. Of course, old age is full of sorrows, but life experience gives it prudence to endure them with dignity. Wisdom serves as a support for an aging person for the normal perception of all life changes, it constantly reminds him that life does not close its doors to him.

Polypropylene Fiber as a Factor of Reduction of the Total Shrinkage Strain of Expanded Clay Concrete

Statement of the problem. The article presents the development features of the total shrinkage strain of expanded clay concrete, expanded clay fiber-reinforced concrete, expanded clay steel-reinforced concrete, and expanded clay fiber-steel-reinforced concrete. According to the analytical review, the shrinkage strain decrease as a result of the fibers adding was noted by the researchers without analyzing the reason for the phenomenon. Therefore the purpose of the study is to establish the reason for the decrease of the shrinkage strain of expanded clay concrete with the addition of polypropylene fibers. Results. It has been confirmed that the polypropylene fiber addition reduces the total shrinkage strain of expanded clay concrete by 29—34 % on the 120th day with the volume content of fibers of 0.36 %. Empirical dependences of deformations compatibility for expanded clay fiber-reinforced concrete and expanded clay fiber-steel-reinforced concrete are set forth. Conclusions. It has been experimentally established that fiber is a significant factor on the first days of the concrete mixture hardening, when the elastic modulus of the fiber is greater than or equal to the elastic modulus of the cement stone. Fibers act as a bond and affect the redistribution of shrinkage stresses within the composite, thus reducing the values of the total shrinkage strain.

Factors influencing the development of STEM competencies in vocational training: an analytical review of international studies

Is it necessary to diagnose and correct vitamin D deficiency in malignant neoplasms? Analytical review

BACKGROUND: Although the critical role of vitamin D in mineral homeostasis regulation is widely recognized, the global prevalence of vitamin D deficiency is exceedingly high. The substantial number of population-based studies that examine the correlation between the concentration of circulating vitamin D levels and the risk of developing cancer may be attributed to the growing interest of researchers in this vitamin as a suppressor of proliferating epithelial cells. However, the data collected are contradictory. AIM: To ascertain the necessity of diagnosing and rectifying vitamin D deficiency in cancer patients. MATERIALS AND METHODS: The keywords “vitamin D,” “vitamin D deficiency,” “cancer,” and “survival” were employed to identify publications in the e-Library, PubMed, and ScienceDirect databases from January 2014 to January 2024. Based on the data obtained, an analytical review of the literature was conducted. RESULTS: The global prevalence of vitamin D deficiency, including among cancer patients, is exceedingly high and does not vary by sex, age, or ethnicity. Decreased serum vitamin D levels are linked to an elevated incidence of colorectal cancer, breast cancer, melanoma, prostate, and pancreatic cancer. Addressing vitamin D deficiency helped mitigate the risk of developing breast cancer. Data on the effect of vitamin D deficiency and its correction on patient survival are inconsistent. CONCLUSION: Currently, there is no consensus regarding the impact of vitamin D supplementation on the incidence of diverse malignancies, as well as tumor-specific and overall survival. Additional research is required to address the necessity of diagnosing and correcting vitamin D deficiency.

Schools and industries producing educational-labor paths in secondary TVET in Chile: Who sets the skills agenda?

This research studies the relations and articulations between two schools from the Antofagasta Region, located in the mining north of Chile, and three of mining companies in the country, which have part of their main operations in the surrounding territories of these schools. This study interrogates the forms of articulation between these schools and the companies, analyzing the main actions, agendas and institutional purposes that both the schools and the companies seek regarding each institutional needs and perspectives. We critically examine these articulations and relationships because, as a result of Chilean public policy in the area of TVET, which is intended to be an industry demand-oriented training policy, the mining industry is actively influencing the school training processes and curriculum, which does not necessarily result in the acquisition of relevant and significant skills for students. This study was designed from a qualitative approach, through the application of two-rounds of situated in-depth interviews to schools’ managers and professionals from mining companies from the north region of Chile. The findings illustrate the ways in which different efforts, contributions and formative actions provided by the companies are reshaping the educational processes inside the schools, establishing educational agendas that expect to provide more efficient alignments between the schools and the companies’ labor needs. Specifically, the paper argues that mining industry companies promote a reduced technical skills approach. This does not include long-term educational planning within the schools, and alternative technical, relational and transformational approaches to skills are absent. The former conventional notions of vocational education and training are being challenged by theoretical and empirical literature. A critical discussion on the skills agenda setting in VET systems is also presented. This study offers an original analytical review and an in-depth study on the dynamics and discourses that articulate and motivate the collaboration between VET schools and mining companies in the Chilean North.

Role of innovation culture and post-Soviet mindset as factors determining speed of economic development in a small open economy: Case of Latvia

This research seeks to identify the value of a few common factors determining the speed of economic growth in Baltic states and analyzes their impact in detail on Latvia’s lagging. Latvia’s economic starting point after regaining independence because of the collapse of the Soviet Union was at least comparable to its neighbors. Still, after the implementation of liberal reforms towards a free market’ economy and 20 years of operation as an EU full member, Latvia is lagging in growth, prosperity, and innovation. Within the analysis, this scientific paper pays special attention to the three less discussed factors, namely, the impact of post-Soviet mind-set effects as a part of local innovation culture, lasting since regaining independence in 1991; the importance of the availability of talent pull, its density, diversity, and accessibility; and readiness and capability to capture external knowledge and technology adoption. The overall approach is the systemic assessment of the national innovation system and/or innovation ecosystem, trying to understand the differences between these two models. Research is performed by analysis of the performance of the local innovation ecosystem in connection with export- and Foreign Direct Investment (FDI) policies. The authors present a novel method for visually representing economic growth and its application in analyzing process development within transitional economic nations. The study uses an analytical and synthetical literature review. It offers a new GDP data visualization method useful for monitoring economic development and forecasting potential economic crises—the outcomes from aggregative literature analysis in a consolidated concept are provided for required talent policy proposals. The post-Soviet mindset is seen as a heritage and devious underdog that has left incredibly diverse consequences on today’s society, power structures, economic growth potential, and the emergence of healthy, well-managed, and sustainable innovation ecosystems. The post-Soviet mindset is a seemingly hidden and, at the same time, an intriguing factor that has a significant impact on the desire to make and implement the right decisions related to innovation, education, and other policies promoting business development. The key outcome of the article is that sociocultural aspects and differences in innovation culture led to a slow-down of Latvia’s economic growth compared to Estonia’s and Lithuania’s slightly more successful economic reforms.

The Dimensions of Political Speech – Conceptualising the Origins of Political Hostility

This paper introduces a novel theoretical framework to analyse the increasing polarisation and hostility within US politics. The framework categorises political speech into three interrelated dimensions: locutionary, perlocutionary and illocutionary. By conducting an analytical review of the literature on political behaviour and polarisation and conceptualising the debate within this framework, the paper concludes that the increasing hostility is predominantly influenced by transformations within the illocutionary dimension rather than by changes occurring within the locutionary one.

An Analytical Review for Search of Optimal Selection & Utilization of Earthwork Equipment in Construction

Different types of equipment with various levels/times application times are the characteristic features of all construction projects. Almost every construction project/industry has the most common problem of slow progress and cost overruns due to increasing downtime and decreasing operational efficiency of construction equipment. Construction equipment is involved in construction to such an extent that without it no construction activity can be performed. In recent years, with the continuous advancement in technology and improvement of urbanization, there have been more and more construction project/equipment requirements resulting in either the project delay or cost enhancement As the most critical element earthwork is responsible for not only successful completion of project within schedule but also for the starting of the project, selection of right equipment for earthwork is necessary. Earthwork complexity further increases due to various soil types and equipment, and adverse environmental conditions The present study is concentrated or focused on soil and various costs based practices adopted for the selection of construction equipment and an attempt has been made to find the optimal solution for the most problematic or responsible activities for the delay in project/cost overrun especially in context to excavation, compression, and earth / material movement equipment utilization.

Phase Equilibria in the Li–V–O System (an Analytical Review)

The evolution and causes of the change in the demographic model of Russia. Message 1. General assessment of historical, medical, social and demographic events

The demographic situation in different periods was determined by the general patterns of childbearing, epidemics and the state of society. In Russia, even against the background of great upheavals, population growth has been observed for several centuries with a high birth rate, which exceeded the total mortality rate. Epidemics, wars and political events of the twentieth century, as well as the change of priorities in the 1990s, left their mark and led to a decrease in the population. This analytical review is devoted to the evolutionary changes in the Russian population model. The main historical, medical, social and demographic events that dynamically affect the demographic situation in our country are considered. Special attention is paid to the factors influencing the decline in the population in the country, which must be taken into account when planning and implementing state and territorial programs to stimulate the birth rate, taking into account the main political and economic changes.

New challenges regarding the environmental and sanitary condition of Ukrainian water bodies

Today Ukraine is faced with new challenges that have a significant impact on natural water bodies and aquaculture. As a result of hostilities, there is an additional pressure on aquatic ecosystems. Unfortunately, large territories with important fishery complexes of Ukraine are either occupied, located in the war zone, or mined. Currently it is impossible to carry out comprehensive monitoring investigations into the actual environmental condition of inland water bodies of Ukraine. Therefore, in order to establish a true picture of the state of the water fund of Ukraine, an analytical review of publications was performed. Unfortunately, after the large-scale hostilities on the territory of Ukraine, a significant number of water bodies changed their status according to saprobic indicators. The situation is difficult with the reservoirs of the Dnipro River Cascade, which accumulate all pollutants released into the water from the catchment area. The destruction of the Kakhovka Hydroelectric Power Station led to a massive killing of all biota, including fish. The reservoirs are mostly polluted by biogenic, organic and surface-active substances, oil products, phenols, pesticides, and heavy metals. Even in the pre-war period, the problem of water pollution required immediate decisions, and with the beginning of the full-scale war, it became one of the most urgent tasks for Ukraine. Today, Ukraine’s water bodies suffer from pollution by pyrogens, fuel, and lubricants after rocket attacks and even from the total destruction of fish farms, water reservoirs, i.e., the Kakhovka Reservoir. Therefore, monitoring of the environmental condition of inland water bodies of Ukraine will provide an opportunity to assess their real condition and, in the future, to select the complex of methods aimed for their restoration.

Презумпция необходимой зрелости сознательно-волевой сферы физического лица

The article examines the types of legal presumptions, provides an analytical review of the literature, as well as the opinions of civil scientists on the topic under study. Based on the theoretical analysis, a definition of the concept of civil capacity of an individual as a presumption of the necessary maturity of the conscious-volitional sphere of an individual has been developed. It is stated that, in the presence of legal facts indicating a negative impact on the conscious-volitional sphere of an individual, such a presumption can be refuted. It is concluded that the refutation of the presumption of the necessary maturity of the conscious-volitional sphere of an individual is the restriction of the civil capacity of an individual, and the legal facts are the statutory grounds for limiting the capacity. The given author's definition allows us to clarify the legal essence and features of the legal capacity of an individual and its limitations, which have theoretical and practical significance in legal science. Keywords: presumption, refutation of presumption, civil law, family law, objective law, legal personality, legal capacity, legal capacity, limitation of legal capacity, legal capacity, legal capacity to commit a delict, social maturity, conscious-volitional sphere, reasonableness, conscientious behavior, legal fact, individual, guardian, trustee.

Mapping Muslim Chaplaincy: An Analytic Review of Publications between 1989 and 2023

Abstract This article analyses the emergent field of Muslim chaplaincy research by reviewing English-language publications in this growing area of professional religious work, especially in Europe and the United States. After presenting the method of our enquiry, we provide a quantitative and qualitative analysis of the literature reviewed. We then focus on three key topics in Muslim Chaplaincy Studies that derive from our quantitative and qualitative research. These are: the training of Muslim chaplains, which is strongly linked to professionalisation, the vocabulary and sources that underpin Muslim chaplaincy and, finally, the significance of the increasing involvement of Muslim women in this area of professional religious work and leadership. Having identified exactly 100 publications related to the development of Muslim chaplaincy, many of them arising from empirical research, serious practitioner reflections located in peer-review publications, and a small number of articles that are explicitly devoted to methodological considerations, we are suggesting in this article that a distinctive sub-field of Muslim Chaplaincy Studies can now be identified.
