The present study explores the Bianchi type I universe in the frame work of f theory of gravity by considering strange quark matter attached to string cloud and domain walls in the presence and absence of magnetism. Field equations are solved by choosing a constant curvature method. It is found that obtained cosmological models are relevant to the early era of evolution of the universe. The strange quark matter may be a source of string cloud and domain walls.

ABSTRACTAdopting a temporally distant perspective on stressors reduces distress in adults. Here we investigate whether the extent to which individuals project themselves into the future influences distancing efficacy. We also examined modulating effects of age across adolescence and reactive aggression: factors associated with reduced future-thinking and poor emotion regulation. Participants read scenarios and rated negative affect when adopting a distant-future perspective, near-future perspective, or when reacting naturally. Self-report data revealed significant downregulation of negative affect during the distant-future condition, with a (...) similar though non-significant skin conductance pattern. Importantly, participants who projected further ahead showed the greatest distress reductions. While temporal distancing efficacy did not vary with age, participants reporting greater reactive aggression showed reduced distancing efficacy, and projected themselves less far into the future.

_Purpose._ This research defines the conceptual foundations of anthropotechnics as a science that studies modern processes of interaction between humans and technologies in the socio-humanitarian dimension. _Theoretical basis._ The authors use the method of anthropological analysis, which allows generalizing the approaches of anthropotechnics in the socio-cultural context in the "human-technology" system. _Originality._ Based on the results of the research, the understanding of the essence of anthropotechnics as a science that studies human interaction with technologies and technical systems has been clarified. (...) The idea of implementing anthropotechnical approaches to the management of the educational process gained further development, in particular in the context of practical training of applicants for education, distance learning, and dual education forms. The concept of professional activity and professional self-realization of the individual is taken into account, and promising directions in the development of anthropotechnics in the context of the application of artificial intelligence are determined. _Conclusions._ Considering anthropotechnics in a philosophical and sociocultural dimension is an important approach to understanding the interaction of technologies, people, and society as a whole, where technologies affect human perception of the world and interaction with it. The range of approaches chosen by the authors, the disclosure of their principles and categories allows for considering the object of this research – anthropotechnics as a modern science – in a multifaceted and holistic way, to interpret the results of the research based on the use of the basic categories of approaches: a person, equipment, technology, activity, development, personality, system.

Even though integrity is widely considered to be an essential aspect of research, there is an ongoing debate on what actually constitutes research integrity. The understanding of integrity ranges from the minimal, only considering falsification, fabrication and plagiarism, to the maximum, blending into science ethics. Underneath these obvious contrasts, there are more subtle differences that are not as immediately evident. The debate about integrity is usually presented as a single, universal discussion, with shared concerns for researchers, policymakers and ‘the public’. (...) In this article, we show that it is not. There are substantial differences between the language of research integrity in the scientific arena and in the public domain. Notably, scientists and policymakers adopt different approaches to research integrity. Scientists tend to present integrity as a virtue that must be kindled, while policy documents and newspapers stress norm enforcement. Rather than performing a conceptual analysis through philosophical reasoning and discussion, we aimed to clarify the discourse of ‘scientific integrity’ by studying its usage in written documents. To this end, large numbers of scientific publications, policy documents and newspaper articles were analysed by means of scientometric and content analysis techniques. The texts were analysed on their usage of the term ‘integrity’ and of frequently co-occurring terms and concepts. A comparison was made between the usage in the various media, as well as between different periods in which they were published through co-word analysis, mapping co-occurrence networks of significant terms and themes.

We present some striking global consequences of a model quaternionic quantum field theory which is locally complex. We show how making the quaternionic structure a dynamical quantity naturally leads to the prediction of cosmic strings and nonbaryonic hot dark matter candidates.

In his discussion of Roman military institutions Polybius described how the desire for fame might inspire Roman soldiers to heroic feats of bravery, including single combat: (6.54.3–4)τ⋯ δ⋯ μέγιστον, οἱ νέοι παρορμ⋯νται πρ⋯ς τ⋯ π⋯ν ὑπομένειν ὑπ⋯ρ τ⋯ν κοιν⋯ν πραγμάτων χάριν το⋯ τυχεῖν τ⋯ς συνακολουθούσης τοῖς ⋯γαθοῖς τ⋯ν ⋯νδρ⋯ν εὐκλείας. πίστιν δ' ἔχει τ⋯ λεγόμενον ⋯κ τούτων. πολλο⋯ μ⋯ν γ⋯ρ ⋯μονο-μάχησαν ⋯κουσίως Ῥωμαίων ὑπ⋯ρ τ⋯ς τ⋯ν ὅλων κρίσεως κτλ. Modern scholars, however, have taken little notice of this remark and some (...) have tried to belittle the importance of single combat at Rome. Thus G. Dumézil alleged that the Romans fought few single combats and that this was significant for their outlook upon war, while R. Bloch described the duels in the seventh book of Livy as ‘un mode de combat absolument étranger à la tradition romaine, mail auquel les Romains ont été contraints par les habitudes et par les défis des Celtes’. W. V. Harris is the only scholar to have understood the importance of monomachy in the Roman Republic, but even he has not assembled all the evidence necessary for an accurate assessment of the phenomenon. This essay is intended to provide a full treatment and thus to make some contribution in a limited but interesting area to our understanding of Roman attitudes to warfare. I have included a list and discussion of all instances of single combat from the Roman Republic which I have discovered and have argued that the custom continued from prehistoric times at least to 45 b.c.

My objective in this project is to explore the concept of moral luck as it relates to sports. I am especially interested in constitutive luck. As a foundation I draw from both Bernard Williams and Thomas Nagel’s classic handling of moral luck, generally. Within the philosophy of sport are similar explorations of this nexus by Robert Simon and David Carr that also factor into the present work. My intent is to put a new lens in front of a puzzle drawn (...) from Torbjörn Tännsjö’s well-known article ‘Is Our Admiration of Sports Heroes Facistoid?’ Specifically, the idea that we might admire an athlete who excels without having worked hard for it. If we may call this puzzle ‘the talent problem,’ the questions driving the present work are as follows: what is the relationship between moral luck and the talent problem, and can this relationship provide a prescription for morally assessing the talent problem? The thesis that this exploratory work suggests that more complex games (and... (shrink)

Herein I address and extend the sparse literature on deception in sports, specifically, Kathleen Pearson’s Deception, Sportsmanship, and Ethics and Mark J. Hamilton’s There’s No Lying in Baseball. On a Kantian foundation, I argue that attempts to deceive officials, such as framing pitches in baseball, are morally unacceptable because they necessarily regard others as incompetent and as a mere means to one’s own self-interested ends. More dramatically I argue, contrary to Pearson and Hamilton, that some forms of competitor-to-competitor deception are (...) similarly unacceptable. Specifically, I offer a ‘principle of caustic deceit’ according to which any strategic deception that divorces a game from its constitutive skills is morally untoward and ought to be met with negative social pressure at least, and/or legislated out of existence. The problem with these forms of strategic deception is that they treat one’s opponents, again in the Kantian sense, as a mere means to one’s own self-interested ends. (shrink)

The thesis of this paper is that games and sports that harm nonhuman animals are unethical because they exceed the permissible limits of optional harm and the more harm the game imposes on the nonhuman animal(s) it objectifies the worse the ethical transgression. Factors in the analysis include the nature of games and sports, the ontology of beings (i.e., human and nonhuman animals) in games, the mitigating power of informed consent among human game-players and its absence among nonhuman game players, (...) harm, and intent.

Students of the play have not appreciated the merits of W. Dindorf's proposal to delete lines 895–7: his conjecture is not reported by most editors; when reported it is not accepted; and it has been taken seriously perhaps only in aniobiter dictumof Wecklein. Nevertheless, the arguments in its favour are even more powerful than Dindorf realised.

The present article contains part of results from my lecture delivered at II Flemish-Polish workshop on Ontological Foundation of Paraconsistency.

Applying Bernard Suits’s conceptual definition of game-playing, and his outline of a conceptual definition of sport, I ask and answer the following question: can hunting be a sport? An affirmative answer is substantiated via the following logic. Premise one, all sports are games. Premise two, a game is a voluntary attempt to overcome unnecessary obstacles. Premise three, fair-chase hunters voluntarily accept unnecessary obstacles. Conclusion one: fair-chase hunting is a game. Premise four, a sport can be defined as a game that (...) requires the exercise of physical skill, has a wide following, and institutional stability. Premise five, some fair-chase hunts require physical skill, have a wide following, and have institutional stability. Conclusion two: fair-chase hunting that requires physical skill, has a wide following, and institutional stability is a sport. After substantiating each premise and conclusion I consider and refute several important objections. Primarily, that hunting lacks constitutive rules and that hunting lacks volitional engagement and thus cannot be a game or sport. (shrink)

In this paper I establish a normative limit of spectator interaction. I argue that attempts by non-participants (e.g. spectators) to affect the outcome of a contest, whether intended or merely foreseeable, are unsporting and ought to be discouraged because they undermine fairness, which is a fundamental premise of ideal competition. Because this is at odds with the participatory ethos of contemporary sports fanaticism (e.g. ?12th man? campaigns, visual distractions by spectators, etcetera) I anticipate several potential objections. I refute concerns that (...) my thesis is empirically dubious; that it is impractical; that it is subordinate to financial considerations; that it is nullified by participant acquiescence; and that it is subordinate to spectator interests.

This work is the first to demonstrate the differences and similarities between Plato's myths and the traditional kind of which he was critical. It also actively demonstrates the extent to which his own myths support or undermine the philosophical ideas of the dialogues in which they are set. It offers new arguments and criticism on point of detail concerning modern interpretations.
