We prove that modal definability with respect to the class of all structures with two commuting equivalence relations is an undecidable problem. The construction used in the proof shows that the same is true for the subclass of all finite structures. For that reason we prove that the first-order theories of these classes are undecidable and reduce the latter problem to the former.

The article examines the earliest evidence of transmission of Indian and Buddhist ideas. The aim is to outline a schematic mental “map” of the first contacts between Ancient Greece and Europe during the early Middle Ages and India in a socio-cultural and religious-philosophical aspect, without claiming absolute comprehensiveness. The historical-philosophical method was used in order to establish the lines of reception, to discover the specifics of the changes during its transmission and, accordingly, the differences that appeared, and to indicate the (...) historical-philosophical connections and moments of “intersection” of the two traditions under consideration. The proposed article is the beginning of a series of articles that will explore in a similar manner the development of the “Indian thread” in Europe until the flowering of mature Indology in the 18th century, as until now there is no similar presentation in the Bulgarian language. The aim is not to bring to the fore a supposed influence on Christianity, nor to debate which came first, but only to show that familiarity with Indian philosophy-religious reality is not something that appears 'suddenly'. The study of the historical-philosophical context of each of the periods would provide clarity on the level of familiarity and the method of reception and interpretation of the "new knowledge" on which to base texts on East-West dialogue in modern times.

Individuals with heavy paid and unpaid work burdens may experience time deprivations that restrict their well-being and put them at risk of becoming or remaining income poor. Because unpaid work outside of the market is not captured in most large survey-based datasets, time poverty is rarely recognized in policy and practice. Yet income poverty and time poverty are mutually reinforcing; they can sap energy and impede effective decision-making, thus perpetuating the state of poverty. This essay offers a five-step approach to (...) conceptualizing and measuring time poverty and it compares time poverty rates by gender across a range of developing countries. Results show that women have higher time poverty rates than men in most cases, with the main exception being countries with low rates of female labor force participation. Policies that strengthen physical and social infrastructure, thereby decreasing the time needed for unpaid household work, have demonstrable effects on reducing time poverty. (shrink)

У статті досліджено взаємозв'язок проблеми самотності та самогубства. Встановлено, що причиною виникнення самотності є втрата почуття єдності людини зі світом та нерозв'язність екзистенційних потреб людського буття. Визначено, що умовою подолання стану самотності й запобігання самогубству є формування почуття єдності людини зі світом.

Over the past years, various accounts of ethical consumption have been produced which identify certain concepts as central to mediating the ethical relationship between the consumer and the consumed. Scholars across disciplinary fields have explored how individuals construe their ethical consumption responsibilities and commitments through the notions of identity, taking care and doing good, proximity and distance, suggesting the centrality of these themes to consumer engagement in ethical practices. This paper contributes to the body of research concerned with unravelling consumers’ (...) conceptually mediated relationship to moral and ethical issues in the sphere of consumption by revealing a new set of ideas through which people interpret and relate to consumption ethics. Drawing upon findings from an empirical study on self-perceived ethical food consumers, I demonstrate that people’s perceptions and views of ethical problems around consumption are bound up with notions of vulnerability, suffering, and harm, and that these notions permeate and impact all aspects of ethical consumer behaviour. The paper concludes by arguing that we need to further explore the conceptual underpinnings of ethical consumer commitments and practices, and expand the conceptual toolkit of research on ethical consumption to account for a wider range of ideas and notions that shape individual as well as collective motivations, intentions, and actions throughout the process of becoming and being an ethical consumer. Finally, the paper suggests a specific analytical framework to facilitate such research. (shrink)

The author tries to find a place of religious education in religious traditions of the Baha'i Faith. The main objectives of the research are: 1. to clarify the meaning of terms "education", "learning", "upbringing" and limits of their application in the field of education of the Baha'i faith; 2. to clarify the meaning of terms "religious education", "religious learning", "religious upbringing" and limits of their application in the field of education of the Baha'i faith; After the analysis of the main (...) terms of research the author introduced two concepts to describe the educational issue in the Baha'i Faith: "Pedagogy of the Baha'i", which is further used in the value system that combines the processes of education, learning and upbringing in the confessional tradition of the Baha'i faith; "Religious pedagogy Baha'i" as a system that combines the processes of religious education, religious learning, religious upbringing. Pedagogy Baha'i is used in schools, colleges, universities and other social and educational projects, created on the initiative of the Baha'i believers and religious principles of this religious tradition. Religious pedagogy Baha'i describes the processes of providing religious knowledge, skills and abilities (the study of the Scriptures and the sacred history of the Baha'? faith, learning the rules of the confession of religious traditions and religious activities, etc.), and upbringing in the spirit of the Baha'i believers - inculcation of religious virtues. The author comes to the conclusion that religious pedagogy Baha'i originates from the main purpose of religious revelation of Baha'u'llah - teaching people the rules of life, the Laws of God, the faith.

The current state of Ukrainian society is characterized by socio-economic instability, there are dynamic, unique processes in which each person is involved. In this connection, there are increasing demands on the professionalism of specialists in the field of practical psychology, their philosophical counseling in the context of postmodernism, aimed at helping people become the subject of their life, work, social and value relationships, to teach them to find meanings and maximize self-actualization. This is represented in the change of priorities in (...) the professional development of practical psychologists, its focus on the development of specialists' subjectivity, their ability to independently solve professional and life tasks. An important role in enhancing the development of professionalism is the understanding of the essential characteristics of existential professional activity, expressed most often in professional meanings and values. The basis of a meaningful professional and personal life is the key ability of the practical psychologist to see and accept the needs of the profession and life and to find the most correct explanations for them. The purpose of the article is to investigate the importance and necessity of the activity of a practical psychologist, its peculiarities, the study of types of psychological aid: counseling, psychological rehabilitation, correction, psychotherapy, training, education and prevention; as well as the need to identify the main areas of professional activity of practical psychologists in the context of postmodernism.

In this study, we analyze the development conditions of and trends in Ukrainian scientific art during the ongoing war with the Russian Federation. Based on our own experience, we demonstrate how the emphasis, values, and goals of scientific art shift under martial law. We also highlight the challenges and difficulties faced by Ukrainian artists and researchers who found themselves in the occupied territories. Our own experience involves the promotion of the scientific and artistic project “Nanoart. Science is art” and its (...) transformation into a socio-patriotic project “Nanoart. New symbolism of science.” We use this example to show how trends in art, culture, and science change very quickly under critical conditions. Art during the war has military and liberation themes, while artists and scientists during the war are warriors on the cultural and scientific fronts. (shrink)

This article addresses concerns about the relationships between practice and theory in today's theatre and examines the discipline's analytical methodology. This contribution re-introduces Yuri Lotman's concept of semiosphere as an anthropological and social space of communication, in which every participant maintains their existence concurrently across temporal, linguistic, and cultural zones. Finally, by launching the notion of a theatrical semiosphere that embraces the dynamics of cognitive impulse in the tripartite proximity of the space of the stage, the space of the audience, (...) and the space of the “in between,” this study seeks to demonstrate how the transitory nature of theatrical communication directed at the multiple audio-visual, cognitive, and cultural sensors of actors and spectators can still be considered and studied from the perspective of semiotic exchange as the primary device of human cognition.

This paper provides a detailed comparison between discourse representation theory and dependent type semantics, two frameworks for discourse semantics. Although it is often stated that DRT and those frameworks based on dependent types are mutually exchangeable, we argue that they differ with respect to variable handling, more specifically, how substitution and other operations on variables are defined. This manifests itself in two recalcitrant problems posed for DRT; namely, the overwrite problem and the duplication problem. We will see that these problems (...) still pose a challenge for various extended compositional systems based on DRT, while they do not arise in a framework of DTS where substitution and other operations are defined in the standard type-theoretic manner without stipulating any additional constraints. We also compare the notions of contexts underlying these two kinds of frameworks, namely, contexts represented as assignment functions and contexts represented as proof terms, and see what different predictions they make for some linguistic examples.

The essay offers lyrical and philosophical-aesthetic reflections on the power and unpredictability of the feeling of love, as celebrated in different times in the “Song of Songs,” in Russian philosopher Vladimir Soloviev's sophiology, and in the poetic work of Oscar Wilde and Russian religious poet Nikolai Klyuev.

This paper engages with two contrasting approaches to conceptualising and studying consumer behaviour that appear to dominate existing research on consumption. On one hand, agency-focused perspectives take an individual consumer to be the primary author of practice and a basic unit of analysis. On the other hand, socio-centric paradigms focus on the social roots of consumption activities and the wider societal contexts in which they take place. The need to provide a more balanced view of consumption phenomena has been acknowledged, (...) yet not adequately acted upon. This paper begins to fill this gap through relevant theoretical and empirical contributions. First, we provide a critical review of the dominant theoretical perspectives on consumption in general and ethical consumption in particular, highlight their key ontological assumptions and explain how they preclude a fuller understanding of the ways in which consumer practices are moulded and shaped. Taking a critical realist approach, we then present the findings from qualitative analysis of consumers' ethical food practices to empirically demonstrate the role of human agency and social structure in creating and shaping ethical consumption. Thus, by means of theoretical analysis and empirical research this paper responds to the call for a more comprehensive understanding of consumption and provides a consolidated account of consumer behaviour which acknowledges and explains the complex ensemble of individual and systemic powers in which consumer practices are contained.

The article reveals the peculiarities of spreading Reformation ideas in Slovakia during the first half of the sixteenth century. It is emphasized that Reformation ideas were being distributed on the territory of Slovakia in three ways; the Quirinal, in particular, Queen Mary played a significant role in these processes. Leonard Stöckel, a distinguished teacher, theologian, humanist, nevertheless, contributed greatly to the development of these processes. He is the author of «Confessio Pentapolitana», which is one of the oldest documents on the (...) history of Hungarian Protestantism serving as the basis for accepting the forthcoming Symbols of Faith. Stöckel’s outlook was formed under the influence of the European Enlightenment. He established new contacts: Stöckel made friends with an eminent European humanist – Philipp Melanchthon, who was his teacher. The proof of it is a joint edition of Melanchthon’s «Loci communes» and Comments on «Loci communes», which was published posthumously in Basel in 1561. Consequently, at the request of residents of Bardejov L. Stöckel became the headmaster of the town school. In the summer of 1539 he left Wittenberg. L. Stöckel’s return to his hometown Bardejov marked the beginning of a new period in his life. He deceased in 1560. (shrink)

Engineering failure investigations seek to reconstruct the actual causes of major engineering failures. The investigators need to establish the existence of certain past events and the actual causal relationships that these events bear to the failures in question. In this paper, I examine one method for reconstructing the actual causes of failure events, which I call "feature dependence". The basic idea of feature dependence is that some features of an event are informative about the features of its causes; therefore, the (...) investigators can use the features of a known failure event to reconstruct details of its causes. I make explicit the structure of feature dependence and the evidential basis of its key premises, and show how feature dependence works in the investigation of the American Airlines Flight 191 accident.
