Cu₂SiSe₃ as a promising solar absorber: harnessing cation dissimilarity to avoid killer antisites
Authors: Nicolson Adair , Kavanagh Seán R. , Savory Christopher N. , Watson Graeme W. , Scanlon David O.
Published: April 2023

Copper-chalcogenides are promising candidates for thin film photovoltaics due to their ideal electronic structure and potential for defect tolerance. To this end, we have theoretically investigated the optoelectronic properties of Cu₂SiSe₃, due to its simple ternary composition, and the favorable difference in charge and size between the cation species, limiting antisite defects and cation disorder. We find it to have an ideal, direct bandgap of 1.52 eV and a maximum efficiency of 30% for a 1.5 μm-thick film at the radiative limit. Using hybrid density functional theory, the formation energies of all intrinsic defects are calculated, revealing the p-type copper vacancy as the dominant defect species, which forms a perturbed host state. Overall, defect concentrations are predicted to be low and have limited impact on non-radiative recombination, as a consequence of the p - d coupling and antibonding character at the valence band maxima. Therefore, we propose that Cu₂SiSe₃ should be investigated further as a potential defect-tolerant photovoltaic absorber.
Electron-Rich Multicenter Bonding in Elemental Crystals: A High-Pressure Study
Authors: Osman Hussien H. , Otero-de-la-Roza Alberto , Rodríguez-Hernández Placida , Muñoz Alfonso , Manjón Francisco Javier
Published: April 2023

An unconventional bond has been recently proposed to be present in the crystalline phases of phase change materials (PCMs), that has been quoted as electron-rich multicenter (ERM), hypervalent, 3 center-4 electron, resonant, or metavalent bond. It has also been suggested that this bond occurs at high pressure in IV-VI and V2-VI3 compounds that are not PCMs at room pressure, and that are characterized by the combination of a primary covalent ppσ-bond and a secondary bond in which the lone electron pairs (LEPs) are involved. Since the same bonding scenario occurs in most pnictogens and chalcogens at room pressure, our theoretical calculations show that group-V (As, Sb, Bi) and -VI (Se, Te) elements develop ERM bonds under compression as the sixfold coordination is approached, being polonium the only element whose crystalline α and β structures exhibit ERM bonds at room pressure. The ERM bond formation mechanism and how it depends on the type of LEP present in secondary bonds is reported. Since comprehensive understanding of chemical bonding in materials plays a crucial role in explaining structure and physico-chemical properties as well as to envisage applications, this work paves the way for a better knowledge and use of advanced materials.

Сiprus-france relations and problems of region security
Authors: Lyman Serhii , Bielousova Margarita
Published: April 2023

After gaining independence in 1960, Cyprus began to establish relations with other countries. However, the ethnic conflict between Greek Cypriots and Turkish Cypriots in 1974 led to the actual division of the island into two state entities and to various forms of intervention by foreign states, including Greece, Turkey, France and also Great Britain and the United States. The purpose of the article is to analyze the history and current state of Cypriot-French relations, to study the whole range of French interests in Cyprus after gaining independence to the present. Methods used to achieve the goals of the study: historical and comparative analysis, systematization and generalization, retrospective method. The article emphasizes that from the very beginning of the Cypriot ethnic conflict, France has consistently advocated the territorial integrity of Cyprus and condemned the creation of the Turkish Republic of Northern Cyprus. In subsequent years, France contributed to the fact that Cyprus in 2004 became a member of the EU. But bilateral relations became most intense during the presidency of E. Macron in 2017–2022. The economic interests of France in Cyprus are primarily associated with the discovery of large gas reserves on the Cyprus shelf, for which several states are fighting in the Eastern Mediterranean region, among which Turkey is the most active. This struggle stimulates the establishment of military cooperation between France and Cyprus. The related 2017 bilateral treaty, which came into force in 2020, aims to contain Turkey. This treaty, the French-Cypriot military exercises and French efforts to resolve the Cyprus conflict aggravate French-Turkish relations and the political situation in the region. The analysis presented in this article, the study of the experience of these bilateral relations will be important for the development of appropriate strategies for international interactions for post-Soviet states, in particular, Ukraine.

Published: April 2023

Due to a combination of favorable factors, the Islamic Republic of Iran is one of the leading regional states in the Middle East and one of the prominent geopolitical actors on the world stage. Successful location at the crossroads of the East-West and North-South international routes, the presence of significant resource and geopolitical potential allow Iran to form and adhere to its own foreign policy. The state's promotion of its own interests in the Middle East, activities in other parts of the world, development of nuclear, space and missile programs in combination with opposition to the above by Western countries and regional rivals determines Iran's special role in the international arena. The determining factor is that the country has been subject to various types and severity of international sanctions for the past 40 years, and political, ideological and ethno-religious factors limit the traditional possibilities of the country's foreign policy, which is offset by Iran's flexibility. The study focuses on the foreign policy of the Islamic Republic of Iran. The aim of the work is to investigate a set of factors and actions that allow to designate the Islamic Republic of Iran not only as a key regional player in the Middle East, but also as an important geopolitical actor on the world stage. To achieve this goal, the following tasks were set and solved, namely, the current geopolitical problems of Iran were analyzed and further prospects for cooperation between Ukraine and Iran were identified. Methods of analysis and synthesis were used during the study. The special relevance of the study of IRI's position in the international arena is due to the insufficient disclosure of this issue in domestic publications of the expert community. While the example of Iran is interesting in terms of ways and tools to form regional leadership, as well as promoting its own positions around the world in the face of constraints on the part of the world community.

In the context of the COVID-19 pandemic, the demand for spa treatments began to decline significantly and this led to the partial or complete cessation of a number of spa complexes. In this situation, the beauty industry began to rapidly lose its credibility in the international service market. Restoring the position of the SPA industry is possible under the conditions of adequate response and rapid adaptation to modern challenges. The subject of the research in the article is the peculiarities of hotel SPA operation during the COVID-19 pandemic. The goal of the article is to determine measures to increase the efficiency of SPA hotels in pandemic conditions. Objectives: elucidation of the concept of "SPA" in modern scientific discourse, as well as the development of mechanisms for optimizing the operation of hotel SPAs in a period of crisis. General scientific methods used to achieve the goal of research: analysis, synthesis, systematization, comparison, abstract-logical method. The results of the study show that the COVID-19 pandemic has significantly changed people's lives. On the one hand, the majority of the population has become much poorer, which has affected their well-being, and on the other hand, the consequences of the disease have led to impaired physical and mental health. In the current situation, in order to maintain and restore the health of the population, SPA institutions should offer consumers loyal prices, individual approach to each client, expand the range of contactless SPA services, implement innovative rehabilitation programs aimed at restoring the body to the post-COVID period in accordance with all anti-epidemic safety measures. Conclusion: therefore, the competent construction of a strategy to maintain health and well-being will allow owners to increase the efficiency of hotels through interesting proposals that will improve profitability, length of stay, cross-selling and retention rates.

СODING TO REDUCE THE ENERGY OF DATA MOVEMENT
Authors: Yareshchenko V. , Kosenko V.
Published: April 2023

The problem of reducing power dissipation in global interconnection lines while maintaining high performance is considered in the paper. High switching activity leads to significant communication losses due to communication capacitances between long lines. New byte-addressed non-volatile memory technologies, such as phase change memory, enable systems with large persistent memory, improving reliability and potentially reducing power consumption. However, these technologies only support a limited number of write operations over the lifetime per cell, and consume most of their power when the state of a bit changes during a write. Low power coding techniques are required to reduce switching activity during device-to-device or on-chip communications. The purpose of the article is to develop a method for constructing a set of unit distance codes, analyzing their characteristics and choosing codes that satisfy the given properties. The address bus coding methods with the least switching activity are considered. To reduce dynamic energy losses in the address bus and minimize communication losses between closely spaced lines, Gray code is used, which has a number of disadvantages. Conclusions. The type of codes that have the same properties as Gray codes, i.e. unit distance codes, is determined. A method for constructing a set of unit distance codes, analyzing their characteristics, and choosing codes that satisfy the given properties has been developed. By using the entire set of codes, developers have more choices than using only Gray codes, and this leads to better results.
PROSPECTS FOR THE DEVELOPMENT OF MODERN SCIENCE: EDUCOLOGICAL ASPECTS
Authors: Melnychenko Olga
Published: April 2023

The article is devoted to the analysis of futurological research as a scientific method of forecasting the future development of society in general and the educational sphere in particular. The author provides a general description of futurology, reveals the specifics of future research and singles out the methods and technologies used by futurology. The fact is emphasized that unlike astrology or utopian concepts, futurology relies in its forecasts on a set of methods borrowed from other scientific fields. The article emphasizes the importance of analyzing past and present events, developing alternative options for the future development of society in general and education in particular. The author emphasizes the interdisciplinarity and transdisciplinarity of futurological research and draws a parallel between futurology and educology as scientific directions that aim to predict future social development, determine its trends and specifics. The author pays special attention to the characteristics of the complex of research methods of futurology, as borrowed from the natural sciences, in particular mathematics, physics, cybernetics, etc. The article highlights the trends and directions of education development, which will be the main guidelines for the quality of education in the future. Futurology is a branch of social knowledge that deals with the analysis and development of concepts of the future by extrapolation of existing technological, economic or social trends, as well as substantiating the forecast of the development of future trends. Extrapolation is just one of the methods used by futurists when studying the future. When developing futurology, scientists aimed to create a new science, a kind of «philosophy of the future», which would focus on scientific and theoretical exploration and oppose utopian concepts. Today, futurology is considered as a science that is free from any ideological and socio-utopian doctrines, as a branch of social science, the task of which is to develop concepts of the future of humanity, prospects for the development of social processes. The main problems that modern futurology is interested in: 1) definition and evaluation of future development trends, in particular in the educational sphere. To do this, first, some current development trends are singled out and an attempt is made to characterize them in a certain way, to determine their possible influence on each other, and to describe their possible interaction under various scenarios; 2) identification of regularities among a variety of specific single determinants; 3) coverage of the analysis of the entire system (for example, the educational sphere), based on the identified trends and components of development; 4) forecasting the development of the system in the short-term and long-term perspective, including its development during the century under various possible circumstances; 5) using a combination of instincts and logic during research, and not just rational thinking.

Currently, among the many existing types and forms of education, distance learning is becoming one of the priority areas of pedagogical and educational-methodical activities of many universities, colleges, and general educational institutions. Therefore, the main existing traditional and modern types, methods and forms of education are analyzed in the article from the angle of suitability for use in remote form. Special attention is paid to the advantages, psychological and pedagogical features and problematic aspects of distance learning. The comparative characteristics of synchronous and asynchronous modes of distance learning were considered and carried out, the positive and negative aspects of each mode were determined. A general methodology for evaluating the effectiveness of methods, organizational forms, and types of training has been developed, which is based on theoretical and empirical methods of scientific research and makes it possible to objectively evaluate the effectiveness of training for a wide range of educational programs. To evaluate the effectiveness of methods and forms of distance learning, modern methods of scientific research were used. An analysis of teaching methods was carried out, namely methods for acquiring knowledge (motivational-learning, problem-searching, visual, game, reproductive) and methods for improving knowledge, skills and abilities (practical, interactive, creative, control and self-control methods). The results of the study showed that effective types of training are: distance learning, modular learning, interactive learning, dual education, problem-based learning and programmed learning. The most effective and relevant methods of distance learning have been determined: practical, problem-solving, visual, creative, interactive, motivational-learning methods and methods of control and self-control. According to the results of qualitative and quantitative analysis, the most effective forms of distance learning were identified, namely: individual, video conferences, Google applications, independent work, correspondence, free schedule, video training, game training, online chat. The results of the analysis enable teachers to make a qualified choice of the most effective methods and forms for both traditional and distance learning, and also indicate directions for improving the most effective approaches to learning. The intended prospects for further research consist in the improvement of the proposed approaches to increase the effectiveness of the forms and methods of training in order to raise the level of the quality of training.
Use of Media Educational Technologies to Increase Information Competence in the Process of Education of Future Mathematics Teachers
Authors: Burtseva Olena
Published: April 2023

The article describes the experience of implementing media educational technologies in the process of training future mathematics teachers. The current situation in education dictates new requirements for the training of students of higher educational institutions, which consist in the fact that acquiring only special knowledge is not enough in order to be a competitive graduate, it is necessary to develop such abilities of the individual that reveal his individuality and creative potential to the greatest extent. The educational process can be improved by the modernization of the education system and the emergence of innovative learning technologies. The use of media educational technologies in the process of training future mathematics teachers improves the individual learning of students, their motivation and creative ways of creating media tools and increases informational competence in general. The modern educational space cannot be imagined without the use of Internet technologies, where electronic educational resources help to form the necessary qualities in students in an informational and educational environment. Therefore, the use of media educational technologies to increase information competence in the process of training future teachers in the educational activities of a higher educational institution is more relevant than ever. This means that teachers have a completely different approach to imparting knowledge. Using electronic educational resources of the new generation and technological methods of media education, teachers will be able to build courses in an active, interactive mode, in distance learning, in synchronous, asynchronous, and as it happens today, as well as during military operations in Ukraine. In this regard, it is necessary not only to form a modern and well-organized system of theoretical knowledge and skills of teachers, but also to prepare for the effective application of this knowledge in pedagogical activity and to overcome the difficulties that arise when using it. knowledge in practice. According to the results of the obtained empirical data, the effectiveness of the use of media educational technologies in distance learning during the training of future mathematics teachers has been proven.
Methodological Aspects of the First Foreign Language for History and Archaeology Bachelors
Authors: Shkarban Inna
Published: April 2023

The present study aims at methodological grounding of the specific types of foreign language competences for non-philology faculty students enrolled in the First Foreign Language (English) course taught within the first (bachelor) level of the academic professional program 0.32 History and Archaeology. The suggested methodological and conceptual basis outlined in the research has a concrete practical application to address university language teachers in non-philology faculties, curricula designers, professionals, researchers or practitioners in the field of foreign language teaching. The competency-based foreign language author methodology is practically exemplified in the study as a collaborative teacher-student(s) foreign language learning experience to reinforce cognitive competences through brainstorming, intellectual communication and research via formative e-learning educational and methodological complex, its development and implementation. An overall history study is essentially focused on the concept of historical thinking, specifying such cognitive skills as significance, primary source evidence, continuity and change, cause and consequence, historical perspective-taking, the ethical dimension as key research matters of academic history discourse. The fundamental meaning-making aspects of historical accounts theoretically and empirically substantiate that history and historical knowledge are always culturally predetermined, dynamic and open to contestation and discussion. Within the conceptual-methodological model, the issue is open to a broad scientific analysis in terms of cognitive competences in professional history and archaeology settings as well as in the field of competency-based foreign language learning deploying spoken and written discourse for special purposes. Pragmatic competence encompasses discursive strategies of organizing and structuring the general and professional or specialised discourse in terms of its coherence, cohesion, thematic organization, logical reasoning, as well as functional action-oriented knowledge via general or professional-oriented communicative functions performing. From the foreign language studying perspective multimodality approach has clearly envisaged as progressive constituent for further research under the competency-based foreign language learning methodology to apply in non-linguistic specialties.
The Girl in the Bubble: An Essay on Containment
Authors: Mulvin Dylan , McKinney Cait
Published: April 2023

In this essay, we offer a prehistory of contemporary bubbles used in the mitigation of viruses, told through the late 1980s case of Eliana Martínez, an HIV-positive (HIV+) and developmentally disabled Puerto Rican child who was ordered to be confined to a glass chamber within her Florida classroom. Eliana’s mother, Rosa, challenged the use of this chamber as a reasonable disability accommodation in a high-profile lawsuit. We draw on disability studies, critical access studies, and a postcolonial critique to put forward a theory of the bubble as a “structure-within-a-structure”—a zone of limited, restricted, or filtered interaction with the broader social world. Eliana’s bubble demonstrates how institutional practices of accommodation can easily transform into techniques of containment, sanctioned to manage the “infectious subject” within institutions and systems. The bubble is a gathering of social forces and bodily relations. In Eliana’s case, it gathers the necropolitical arrangements of different populations, the coloniality of Puerto Rico, the innocence of childhood, the fatality of an AIDS diagnosis, and the politics of design and disability.
“Loved by Moms and Law Enforcement Alike”: Militarizing Civilian Bodies Through Bulletproof Fashion
Authors: Sutton Barbara
Published: April 2023

Body armor is no longer limited to war and security-oriented occupations. Bulletproof fashion for civilians has joined a domestic “secret arsenal” of sorts, as families with concerns about security acquire technologies to protect body, property, and household members. Bulletproof fashion thrives in the context of fear and anxiety, helps normalize the proliferation of guns and gun violence in US society, and encourages the privatization of what should be regarded as a social problem.
This essay is a part of the Roundtable called “The Housewife’s Secret Arsenal” (henceforth HSA); a collection of eight object-oriented engagements focusing on particular material instantiations of domesticated war. The title of this roundtable is deliberately tongue-in-cheek reminding readers of the many ways that militarisms can be invisible to their users yet persistent in the form of mundane household items that aid in the labor of homemaking. Juxtaposing the deliberately stereotyped “housewife” with the theater of war raises questions about the quiet migration of these objects and technologies from battlefield to kitchen, or bathroom, or garden. Gathered together as an “arsenal,” their uncanny proximity to one another becomes a key critical tool in asking how war comes to find itself at home in our lives.
Teflon: Slipperiness and the Domestication of Toxicity
Authors: Davis Heather
Published: April 2023

Polytetrafluoroethylene (PTFE), conventionally known as Teflon, has remarkable properties: it doesn’t combine with oxygen; no solvent can corrode it; it doesn’t conduct electricity; and it is among the slipperiest substances on earth. Although it is most widely known as a non-stick coating for pots and pans, one of the first applications of the polymer was for seals and gaskets of the separation process of uranium hexafluoride that was key to developing the nuclear bomb. These lesser-known military applications of Teflon are, I argue, part of the slippage from the military to the household. Employing the slipperiness of Teflon as both a quality of its materiality and a provocative concept, this paper will explore how Teflon moved from the large-scale catastrophic fallout of the Manhattan Project to the slow dispersion of everyday toxicity in the home.
