In 2021, the problems of ecology and environmental safety are the most pressing issues for the world scientific community. The basic principles of the national ecological security of Ukraine and the creation of a comprehensive programme to ensure environmental safety, biosecurity, and prevent the spread of dangerous infectious diseases deserve special attention. The purpose of the presented research is to study the issues of environmental safety in Ukraine, in particular, to clarify the specific features of the measures of the international system of environmental safety and their organisation in Ukraine. In the process of research the methods of synthesis and analysis of information, method of classification, method of systematisation, analysis of scientific literature on the researched topic were used. In the course of the research the basic principles of national ecological security of Ukraine were determined. The organisation of an international system of environmental safety requires the adoption of mandatory principles and standards of national conduct, and the establishment of basic principles of cooperation. Global issues, including the environment, cannot be resolved other than by a concerted effort based on consensus. It was determined that ensuring environmental safety and a favourable state of the environment should be recognised as a public priority for development. In practice, this principle means that socio-economic programmes must meet environmental requirements. Ukraine is taking measures to ensure biosecurity, prevent the spread of dangerous infectious diseases and support international efforts in this area. The practical value of the presented study is that it can be used to study the problem of environmental safety. The presented research can be used by theorists and practitioners to study the issue of environmental safety, and used as a basis for further study of the problem
COMPARATIVE ANALYSIS OF THE LEGAL STATUS OF THE HIGH COUNCIL OF JUSTICE IN UKRAINE AND FOREIGN COUNTRIES
Authors: ULIUTINA OLENA A.
Published: August 2022

The need to study certain aspects of the judiciary is explained by the constant updating of current legislation. Given that the Ukrainian legislator has recently paid close attention to the call-up foreign experience, there is an objective need to analyse the legal status of the High Council of Justice, or bodies that perform its functions in foreign countries. The purpose of the article is to conduct a comprehensive comparative legal analysis of the status of the High Council of Justice in Ukraine and abroad. In the process of comparative legal analysis of the status of the High Council of Justice in Ukraine and foreign countries, the following methods were used: formal-legal (dogmatic), comparative-legal and the method of dogmatic (logical) analysis. According to the results of the research, it is determined that the current state of activity of the High Council of Justice is characterised by a certain representation of executive bodies, including judicial bodies. The key task is to work on the development of the judiciary, participation in the administration of judges, and the disciplinary responsibility of prosecutors and judges. It was found that the legislation of foreign states, consolidating the powers of judicial self-government bodies, gives them the right to select candidates for judges, appoint court chairmen, including bringing judges to disciplinary responsibility. Such bodies always involve government officials, including the president. However, it should be noted that the judiciary has exclusive independence from other bodies, including the executive and the legislature, which is manifested in broad powers. It is argued that the world practice identifies two main options for the appointment of judges: appointment by the President or Parliament on the proposal of the Ministry of Justice or the relevant body of judicial self-government (judicial councils); direct appointment of judges by the relevant body of judicial self-government (judicial councils). The study provides a comprehensive comparative legal analysis of the functioning of the High Council of Justice in Ukraine and foreign countries in today’s conditions, and provides specific proposals to improve existing legislation in terms of the activities of the body under study. The materials of this study can be useful for teaching training courses: Judicial system of Ukraine, international law. Also, the submitted proposals to improve the functioning of the body under study can be used by the legislature in considering the possibility of updating special national legislation
A history of biographical research in the United Kingdom
Authors: Merrill Barbara , West Linden
Published: August 2022

Biograpahical researchers in the United Kingdom have been influenced by symbolic interactionism, feminism, oral history, critical sociology, psychoanalysis and what we term an auto/biographical imagination. The latter involves reflexively situating the researcher and her influence, via power, unconscious processes and writing, into the text and by acknowledgeing the co-construction of stories. The focus of much research has been on marginalised peoples, as part of a democratising project to bring more diverse voices and stories into the historical or contemporary social record. It is important to avoid too rigid a distinction between mainland Europe and developments in Britain. Collaboration and dialogue have been extensive, across various research networks, including in the European Society for Research in the Education of Adults (ESREA).

Ao longo dos anos, temos acompanhado como a pesquisa no campo da formação de adultos e, em especial, no campo da formação de professoras/es, tem se constituído a partir de um pressuposto de que a formação docente se dá em múltiplas temporalidades, por meio de um esforço consciente e desejante do sujeito pela sua própria formação. Desde modo, temos percebido o crescimento de uma produção fundamentada nos estudos narrativos (auto)biográficos, delineando um campo fundamentado em concepções teórico-metodológicas que se constitui de referências epistêmicas e uma potência instituinte. Neste estudo, objetivamos refletir sobre os modos como o Grupo Interinstitucional de Pesquisa-Formação Polifonia (UNICAMP/FFP-UERJ) tem pensado a pesquisaformação como uma palavra-conceito que traz princípios dialógicos para pensarfazer ciência, na Educação. Retomamos a trajetória epistêmico e teórico-metodológica da pesquisa autobiográfica, no que se refere à sua construção paradigmática complexa; trazemos para o diálogo a contribuição da literatura estrangeira e os movimentos que já se desdobravam nas pesquisas em Educação no Brasil e, em especial, partilhamos a experiência de uma pesquisaformação desenvolvida no contexto do referido grupo.
Representações sociais do vaqueiro sertanejo contadas por suas narrativas de vida
Authors: Queiroz Ednalva de Araujo , Ornellas Farias Larissa Soares , Garrido Edleusa Nery
Published: August 2022

Estudo psicossociológico sobre figuras do masculino sertanejo, inspirado nos constructos da psicologia social e da psicanálise, para exemplificar como a análise de fragmentos de narrativas de vaqueiros figuram como representações psico-socioculturais que se fundam na história, na cultura, mitos e ritos, que partem do universal e se especificam na construção subjetiva do homem do sertão. A análise do material considerou a sobreposição do Édipo freudiano às estruturas da jornada do herói e da lida com o gado, e a identificação da feitura do próprio nome como objetivo final e destinação da saga. A formação do povo brasileiro, especialmente do sertanejo da primeira metade do século XX, caracterizou-se pela usurpação dos territórios aos povos originários e pela alienação dos corpos negros à terra africana. A vivência da violência institucional e da desigualdade social são superadas simbolicamente pela pega do boi, o Pai com o qual o vaqueiro se identifica, por sua liberdade de gozar do corpo da mãe-terra. Mas é ao Pai, dono da terra, que o vaqueiro pede sua afiliação e reconhecimento. Para o vaqueiro, a superação do sofrimento pelas condições de vida e seu alijamento de uma cadeia simbólica de poder passam pela atualização permanente do mito do herói.
Costureiras: alinhavos de histórias e memórias

Published: August 2022

Este artigo apresenta registros e reflexões acerca da produção e das primeiras exibições do filme de curta-metragem “Costureiras”, documentário que tem por matéria-prima memórias e histórias de vida e de costura de quatro mulheres, com idades entre 60 e 90 anos, que estruturaram suas vidas a partir da profissão de costureira. Em suas narrativas autobiográficas colocam em debate o lugar histórico-social da profissão de costureira e sua relação com a educação das mulheres. Afetos e saberes populares são colocados em cena permeados por questões de gênero, raciais e de classe, bem como traçam um panorama das transformações que a profissão vai sofrendo ao longo do tempo. O texto foca aspectos da produção do documentário e, também, temas que foram ganhando relevância nos debates que se seguiram às exibições do filme. Destacamos o fato de que o filme tem provocado os espectadores a relatar suas histórias pessoais com a costura – a infância entre retalhos e brincadeiras no pedal da máquina, a máquina de costura como um objeto de importância familiar, a costura como um trabalho feminino que permitia às mulheres estarem próximas de seus filhos e garantirem seu sustento e educação.
Recits d’enseignants a propos de l’education a la vie: un exemple de l’approche narrative et biographique au Japon
Authors: Inoue Sunami
Published: August 2022

L’article a deux objectifs. Le premier consiste à présenter une partie de la recherche mobilisant les récits d’enseignants à propos de la vulnérabilité des enfants japonais d’aujourd’hui. Les crises économiques et l’adoption progressive de politiques néolibérales depuis les années 1980 affectent les sphères éducatives tant scolaire que familiale. Les écoles sont confrontées, d’une part, aux nouvelles exigences sur les résultats d’apprentissage des élèves et d’autre part, à la manifestation, chez les écoliers, de différents problèmes sur le plan psychosocial et comportemental. Le phénomène de l’éducation à la vie s’inscrit dans ce contexte de l’inégalité grandissante. Les entretiens compréhensifs et narratifs menés avec les enseignants ont permis de comprendre que les enseignants s’engagent pour l’éducation à la vie selon leur sensibilité éthique dont l’analyse a permis de dégager trois catégories: amour, responsabilité, conviction. Ce résultat a mis en lumière la dynamique de la correspondance phénoménologique entre la perception de la « vie » qu’ont les enseignants par rapport à leurs élèves et leurs pratiques pédagogiques. Dans un deuxième temps, l’article vise à situer l’usage de l’approche narrative et biographique de la recherche présentée dans un contexte japonais. Il suggère, enfin, une perspective de recherche potentielle auprès d’enseignants au Japon.
Life history of Naito Masu: a female pioneer of women’s education in Yamanashi Prefecture in the early Meiji Period
Authors: Kawata Atsuko , Kato Tokio
Published: August 2022

Naito Masu (1823~1901) was the first woman who advocated publicly the necessity of education for women; she did so in early Meiji period (1870’s) in Yamanashi Prefecture. In the Edo period, it was said that women did not need to study for a long time; therefore her achievement of founding a women’s private school and publishing a textbook regarding moral education for women were epoch making activities in the women’s education in Japan. This paper presents Masu’s life history and the process of development, because she is considered a woman who was sensitive to the gap between the education for men and women in developing their own lives. Masu’s activities following the Meiji Restoration are well-known; however, it is unknown about how and where she had been educated prior to this time. There is a travel diary written by Masu, named as “Suruga-kiko” and owned by Yamanashi Prefectural Museum. It is the appropriate source to know the first half of Masu’s life because it is thought to be written before the Meiji Restoration. This paper looks to draw a clear picture of the unknown part of Masu’s life, including her friends and acquaintances before Meiji Restoration, by citing it. She had grown her circle of acquaintances in the area along Fujigawa Highway and Fuji River. This area is associated with Japanese classic literature, as well as with most pupils of Prof. Hirata, lived in Kai no kuni. The author made investigations in the area and interviewed some people who live there now about Masu and the region’s educational history. As the result of this original research, this paper presents that Masu must developed her culture and education there.
Interrelation between biography and ethnography: cultural analysis as an experimental system
Authors: Srinivasalu Sumathi , Selladurai Manjubarkavi , Mathaiyan Muniraj
Published: August 2022

The interrelationship between ethnography and biographic studies has recently become a popular form of qualitative research. The current discourse on this field of investigation refers exclusively to “evocative autoethnography” that draws upon postmodern sensibilities, whose advocates distance themselves from realist and analytic ethnographic traditions. The dominance of evocative autoethnography and biographic has obscured recognition of the compatibility of autoethnographic investigation with more traditional ethnographic practices. Similarly, the modes of cultural analysis also have been systematically revised over a period, changing its variables that took on new cultural projection. The revision of the 1980’s included new approaches, using ethnography to investigate the changing nature of cultural and social forms. At the end of the twentieth century, inquiries drawn towards multidisciplinary tools that could be employed in making cultural analysis more trenchant and revealing. The most widely applied approach by anthropologists in development projects is the ethnographic approach, which investigates the changing nature of culture and applies qualitative/narrative analysis. The challenge for culture change, according to the anthropologist, is to understand the “everyday” form of thinking, expression, verbalization and comprehension. This paper tries to substantiate that performance of expressions are drawn from “cultural schemas”, and such community expression serves to explain more recent community ethnographic transformations. The paper also justifies the voices and expression of community performance as a ritual which has been empirically validated with the appreciation of community-level transformation/adaptation which can perceive to enhance universal ethnographic. The paper justifies the argument through a case study on a tribal-community in India, their voices of expression and the sacred/clandestine sexuality performance which has been incorporated within the public ethnography in order to prove their identity as a “tribe”, compromising their sacred value privacy.

Abstract. Physical-chemical parameters of the Akor River were investigated. The river water was sampled for seven months (February August) in 2019 and analysed following standard procedures and protocols. The results revealed that there were no significant differences (P > 0.05) among all the investigated physical-chemical parameters across stations. Mean values of all the investigated physical-chemical parameters were within Federal Ministry of Environment set standards (2011) except for chemical oxygen demand and pH. Spatiotemporal results revealed that turbidity, total suspended solids, total dissolved solids, and the major cations (Na+, K+, Ca2+, and Mg2+) as well as the major anions (PO43-, NO3- and SO42-), were high during the rainy season months, but water temperature, pH, dissolved oxygen, and biochemical oxygen demand were higher during the dry season months. The percentage of Na+ contents ranged from 15.85 to 16.39%, indicating that Akor River has excellent irrigation water quality. The Nemerow pollution index varied from 0.59 to 0.63, also indicating that the river water is of good quality. The water quality index results varied from 52.70 to 54.50%, indicating that Akor River has a good water quality status. The result of water pollution index revealed that Akor River status is excellent and capable of sustaining biodiversity as well as crop irrigation.

Abstract. The aim of this study was to investigate mercury concentration and forms of its occurrence in the dust component of the atmospheric air (street dust) to assess the geo-ecological condition of the area where coal is mined, processed and transported. The mean mercury concentration of 29 street dust samples collected along a uniform network throughout the city was 36.4 4.7 ng/g, with a minimum (4.6 ng/g) and a maximum (104.6 ng/g) value, respectively. This value was much lower than the mean concentration in soil samples taken previously at the same sites (58.4 ng/g) but higher than the mean concentration in snow solids (29.8 ng/g), which was likely due to precipitation that washed out mercury from the street dust and to the wind blowing. The method of successive chemical extraction revealed a weakly bonded water-soluble form, inorganic poorly sorbed mercury compounds, an organic form of mercury, and mercury associated with minerals. The proportion of each fraction accounted for on average 10.94%, 10.32%, 44.76%, and 33.97%, respectively. Water-soluble and acid-soluble mercury forms were less common. The bulk of mercury had metal-organic and sulfide forms. The study of mercury distribution based on particle size indicated that the mercury concentration increased as the diameter of the grains of dust material decreased. The fine fraction with a diameter of 20 to 50 m contained the bulk of mercury, which stayed in suspension form for a long time before settling on the surface.

Abstract. A membrane test system has been developed for sensitive and specific detection of Hg2+ ions in natural waters. The test system uses gold nanoparticles synthesized by citrate reduction and a nitrocellulose membrane with a band of the conjugate of mercaptosuccinic acid (MSA) and bovine serum albumin (BSA). In the presence of Hg2+ ions, they are reduced by citrate and adsorbed on the surface of gold nanoparticles. The resulting product moves along the membrane of the test strip under the action of capillary forces and specifically binds to the MSA-BSA conjugate with the formation of a visually detectable colored band. The analysis takes 20 minutes without requiring additional manipulations or instrumentation. Under optimized conditions, the detection limit for Hg2+ ions was 0.13 ng/mL. The efficiency of the proposed approach was confirmed by its approbation for the control of natural waters; Hg2+ recovery ranged from 70 to 120%.

Abstract. Insomnia is a widespread pathological condition in the general population, which has numerous social and medical consequences. Sleep disorders in patients with chronic mercury intoxications are much more common than in the general population. This study aimed to determine the most significant differential diagnostic criteria for sleep disorders in patients with chronic mercury intoxications for their further effective treatment. In this regard, we examined 30 patients with chronic mercury intoxications, whose age averaged 56 0.71 years, and 30 patients of the control group, whose age averaged 54 0.66. All patients underwent clinical, neurological, polysomnographic, and psychological examinations, and neurotransmitters were determined in the blood. Discriminant analysis based on polysomnography, psychological testing and neurotransmitter metabolism revealed significant differences in the examined groups of patients for the following indicators: total sleep time (decreased in the chronic mercury intoxication group) and wake within sleep (increased in the chronic mercury intoxication group) based on polysomnography, blood dopamine level (increased in the chronic mercury intoxication group) as well as reactive anxiety level according to the Spielberger-Khanin scale (increased in the chronic mercury intoxication group). Taking into account the data obtained, it is possible to improve approaches to the diagnosis and treatment of insomnia in the presence of chronic mercury intoxication.

Abstract. The paper presents a case study of mercury in two types of paleoarchives: ice cores and prehistoric animal hair, to assess the potential of Hg using as a proxy for environmental and climate changes. Belukha ice core is well-suitable for reconstruction short-term and long-term Hg deposition, recording global and regional, natural and anthropogenic emissions as well as regional climate changes during 320 years. Hg concentrations in hair of mammoth fauna mammals reflect the variation in Hg level in the environment during period from 45 to 10 ka yr BP. Hg concentrations changes following climatic changes are in a good agreement with other paleoarchive data (Hg fluxes of the EPICA Dome C ice core and Lake Baikal sediments).

Abstract. The problems of coal dust emission are relevant in the coal industry. The greatest danger is represented by coal dust with particle sizes of less than 10 and 2.5 microns. Such fine airborne dust can have a negative impact to human health, susceptibility to weathering, tendency to long-term environment damage, settling on the soils and transferring into waters. The contents of coal dust must be controlled, therefore coal dust was included in the list of pollutants regulated by Hygenic standards GN 1.2.3685-21. It is well known that coal dust may contain potentially hazardous elements, the concentration of which is determined by the form of their occurrence in coal. Among these potentially hazardous elements, mercury compounds are the most dangerous. In this regard, works aimed at assessing the distribution of mercury in coals and airborne dust are relevant. The current paper presents the results on the determination of mercury contents in coals and airborne dust that was collected from them. Also, the granulometric composition of dust particles was shown.

Abstract. In addition to carbon, oxygen, hydrogen and nitrogen, fossil fuels contain other chemical elements, some of which may be hazardous to human health and the environment. Mercury and its compounds are one of the most dangerous among them. Therefore, information about mercury contents in coals and products of their processing is extremely important for both mining and processing enterprises and consumers. Mercury compounds may be accumulated in coal mining and processing wastes, and if they transfer into water-soluble forms, may lead to damaging of the environment. In the view of above, a standard method for the determination of mercury content has been developed, which is applicable not only to coals and products of their processing, but also to coal mining and combustion wastes. Also, to control the correctness of measurements by the developed method, reference samples with a certified mercury contents were developed.

The calla lily ornamental plant (Zantedeschia aethiopica) is grown and marketed in many countries. Studies on daily variation in photosynthesis are critical for understanding how a plant behaves in its growing environment. The objective of this study was to evaluate the daily photosynthetic course of calla lily plants grown in pots in a greenhouse under 50% shade. Gas exchange (gs, A, E, Ci, WUE, iWUE, and iCE) and chlorophyll indices (a, b, and total) were evaluated from 7:00 a.m. to 5:00 p.m. over three days. The values of all variables were greater at high temperatures (11:00 a.m. to 1:00 p.m.), except for gs, Ci, and chlorophyll b, which were higher at low temperatures (7:00 to 9:00 a.m.) Therefore, it is suggested that calla lily producers maintain the water status between 11:00 a.m. and 1:00 p.m. to optimize photosynthetic processes, and consequently, the growth and development of this plant. Correspondingly, irrigation of this crop should be performed prior to the interval mentioned above.

Purpose: Starting from the goal of economic development associated with environmental protection activities, this study examines the factors affecting the application of environmental accounting (EA) in manufacturing enterprises in Vietnam.
Methodology: This study is conducted using a combination of qualitative research methods (review of previous theories and research papers related to the research) and a quantitative research model (testing the degree of the appropriateness of the scale and the theoretical model through Cronbach's Alpha reliability coefficient, exploratory factor analysis (EFA), multivariable regression analysis to determine the relationship between factors affecting the application environmental accounting in manufacturing enterprises in Vietnam.
Results: Multivariable regression analysis shows that all factors (six factors) included in the study have an impact on the application of environmental accounting in manufacturing enterprises in Vietnam. Which stakeholder pressure has the strongest impact and financial resources have the weakest effect on the application of EA in these enterprises.
Originality/Value: This study provides empirical evidence about the impact of each factor on the application of environmental accounting, thereby helping state management agencies, professional associations, and businesses in the process of developing and promulgating policies affecting these factors to promote the application of environmental accounting in Vietnamese enterprises.
Effectiveness of Mergers and Acquisitions in Maltese Listed Companies: Financial Performance, Market Reactions and Shareholder Value

Published: August 2022

Purpose: W The objectives of the paper are to assess the effectiveness of mergers and acquisitions (M&A) in Maltese listed companies on acquirers’ financial performance, to examine the market reactions to M&A announcements and to seek to obtain further insights on the perceived value arising from M&A activity.
Methodology: The methodology involved an Event Study on acquirers’ share price movements and semi-structured interviews with relevant company representatives and Maltese stockbrokers.
Findings: The findings of the paper indicate that the few M&A cases wherein profitability -measured by growth in earnings before EBITDA - was enhanced and operational efficiency was improved took sound financing decisions despite facing challenging circumstances. The Maltese market was generally non-reactive within relatively short timeframes around announcements although with positive reactions within longer estimation periods. Furthermore, the perceived value by acquirers and stockbrokers varied considerably, yet such value was commonly attributed to effective due diligence and successful integration. The study therefore concludes that recent M& A activity in Malta has often been limited in its effectiveness towards enhancing shareholder value.
Originality/Value: the paper provides both corporate managers and stockbrokers with insights into M&A activity particularly in a small-state market.

The experience of JSC Element, a certified developer and manufacturer of components for aviation equipment, is described in terms of introduction into the product development process, namely, their hardware, the requirements and recommendations of the RTSA DO-254 avionics design assurance manual, similarly earlier implemented RTSA DO-178 for the firmware of said products. The need to introduce these documents developed by the Radio Technical Commission for Aeronautics is due to the desire of domestic developers and manufacturers of aircraft products to integrate into the system of international cooperation in the field of aircraft manufacturing. Brief results of the comparison of the requirements of DO-254 with the requirements of the national standard DSTU 3974–2000 for development in terms of the sequence of stages and the content of work are given. It is shown that, working in accordance with the requirements of the current domestic system of standards, Ukrainian development enterprises (including Element JSC) sufficiently ensure the completeness of the passage of what is called in the implemented Guide DO-254 "life cycle of hardware design" and that the main differences are in the form of documentation of development processes and results. Differences in the concept of planning according to DO-254 and in domestic practice are considered, and analogies are redrawn between plans in the interpretation of DO-254 and documents traditional for the system of domestic standards. In terms of the practical development of the forms and methods for documenting the life cycle processes of the development of onboard equipment, the company JSC "Element" is currently at the initial stage, introducing them for the first in the development of the RDC-450M-117V regulator for the aircraft engine TV3-117VMA-SBM1V. The prospects for the work of the enterprise in this direction are outlined, including the integration of the requirements and recommendations of DO-254 into the system of enterprise standards operating within the framework of a certified quality management system.
