In many cases medical diagnosis is based on information obtained through a process involving the emission of different forms of ionizing radiation. The safety of the medical staff and patients exposed to ionizing radiation is highly dependent on the proper design of the shielding used in the laboratory. Therefore, the authors propose a multi-platform application supporting such a design through the computation of the critical parameters of shielding. The specific requirements for shielding are defined by government authorities so the algorithm (...) must comply with all the written standards. The application was implemented using Xamarin. Forms for cross-platform development. The results obtained with the use of the developed tool were compared with those calculated manually for the design of stationary shields developed, deployed, and validated by local inspection.

The paper offers a critical analysis of the skeptic’s conviction that his doubts about the truth of thought on existence of the world outside the mind are not equivalent to real the doubts about existence of the world alone, but they are only a theoretical and speculative problem of knowledge. The main case of this criticism is based on the Kazimierz Ajdukiewicz’s philosophy, precisely, on his theory of truth.

Traditional martial arts continue to be interesting and inspiring to many people around the globe. Some of their contemporary adaptations attract enthusiasts for whom they are especially important. In this article, the author bases his observations on his own long-term participation. The analysis takes into account the influence of the perspectives of Jigoro Kano and several other creators of modern varieties of Japanese budo. It can be concluded that regular, even daily, practice—cultivating martial arts and internalizing its values—co-creates the lifestyle (...) of instructors and advanced students. (shrink)

Kazimierz Twardowski attributed high cognitive value to introspection because he believed it plays a fundamental role in psychology, the primary philosophical discipline. He believed that basing philosophy on inner experience would allow it to obtain universal and justified results. Internal experience consists of perceiving one’s own mental facts; it is non-sensual and selfevident. Twardowski referred to introspection in his investigations in various ways, which is presented in the article.

The Limits of Cognition and the Shape of Being Based on the Thought of Karl Jaspers The article points out the elements of Karl Jaspers’ epistemological conception that cross out the possibility of a comprehensive account of being. The key issue here is the limits of cognition, which take the form of object cognition. The theme of limits points to the inadequacies of human thinking in the context of quantifiable and absolutist representations of reality. The impossibility of adequately grasping the (...) totality of reality will be illustrated here by means of the criticism Jaspers levelled at absolutising metaphysics. In connection with the description of the structure of cognition proposed by Jaspers, the article points out the conceptual proximity of the issue of worldview and metaphysics in the light of the thought of the cited author.

Expression of physical motion (e.g., man runs by) shows systematic variability not only between language types (i.e., inter-typological) but also within a language type (i.e., intra-typological). In this study, we asked whether the patterns of variability extend to metaphorical motion events (e.g., time runs by). Our analysis of randomly selected 450 physical motion (150/language) and 450 metaphorical motion (150/language) event descriptions from written texts originally produced by German, Polish, and Spanish authors showed strong inter-typological differences in the expression of both (...) event types. German and Polish speakers differed from Spanish speakers in how they packaged manner and path components of a motion event; they also differed in how extensively they expressed each component in their lexicalization of motion. The strong inter-typological differences were accompanied by more modest intra-typological variability: Polish and German writers differed in their packaging and lexicalization of manner and path components of metaphorical—but not physical—motion events. Our results provide evidence for robust inter-typological differences evident in the expression of both physical and metaphorical motion, along with less robust intra-typological differences, largely evident in the expression of metaphorical motion. Our study thus highlights event type as an important factor in determining crosslinguistic variation in motion expression. (shrink)

We propose a non-standard interpretation of Alternating-time Temporal Logic with imperfect information, for which no commonly accepted semantics has been proposed yet. Rather than changing the semantic structures, we generalize the usual interpretation of formulae in single states to sets of states. We also propose a new epistemic operator for ?practical? or ?constructive? knowledge, and we show that the new logic (which we call Constructive Strategic Logic) is strictly more expressive than most existing solutions, while it retains the same model (...) checking complexity. Finally, we study properties of constructive knowledge and other operators in this non-standard semantics. (shrink)

SummaryThe Bohr‐Einstein debate on the interpretation of quantum mechanics may be viewed as a discussion on the epistemological status of knowledge gained by physics. It is shown that in fact the advent of quantum theory has led, in a new context, to an old philosophical controversy between epistemological realism and phenomenalism . An inquiry into this controversy, taking into account the contemporary understanding of quantum mechanics based on the axiomatic study of its foundations, leads to the conclusion that contrary to (...) widespread opinion, it is perfectly possible to formulate quantum mechanics in an entirely realistic manner according to the postulate of Einstein. We demonstrate that Bohr's episteme‐logy, in which the role of experimental arrangements in the physical description is taken as a starting point, does not necessarily imply phenomenlism, but may be justifiably considered as a complementary standpoint to the realistic epistemology of Einstein, which is based on the notion of a mental construction which pictures reality.

In [5] we study Nonassociative Lambek Calculus augmented with De Morgan negation, satisfying the double negation and contraposition laws. This logic, introduced by de Grooté and Lamarche [10], is called Classical Non-Associative Lambek Calculus. Here we study a weaker logic InNL, i.e. NL with two involutive negations. We present a one-sided sequent system for InNL, admitting cut elimination. We also prove that InNL is PTIME.

With the meaning of trust, good faith and respect for promises made, protection, or assistance, fides in the non-exclusively religious sense of the word comes from the demand for ethical perfection: as such, it is omnipresent in human relations and in the dynamic of societies in the Middle Ages.

We prove the finite model property (fmp) for BCI and BCI with additive conjunction, which answers some open questions in Meyer and Ono [11]. We also obtain similar results for some restricted versions of these systems in the style of the Lambek calculus [10, 3]. The key tool is the method of barriers which was earlier introduced by the author to prove fmp for the product-free Lambek calculus [2] and the commutative product-free Lambek calculus [4].

Lawrence Nelson (2018) criticizes conscientious objection (CO) to abortion statutes as far as they permit health care providers to escape criminal liability for what would otherwise be the legally wrongful taking of a pregnant woman’s life by refusing treatment (i.e. abortion). His key argument refers to the U.S. Supreme Court judgment (Roe v. Wade 1973) that does not treat the unborn as constitutional persons under the Fourteenth Amendment. Therefore, Nelson claims that within the U.S. legal system any vital interests of (...) pregnant women must always take precedence over fetuses’ interests. While agreeing with the main thesis of the article, we believe that the author’s argument neither vindicates his claim, nor explains why those who believe that fetuses are equally protectable human beings do not have the right to refuse to perform an abortion in lifethreatening emergency circumstances (AE). Therefore, the main aim of our commentary is to outline, by referring to our earlier works on conscientious objection in health care (Z_ uradzki 2016) and cultural exemptions (Ciszewski 2016), a better and universalizable argumentative path that would lead to the same conclusion.

(...) This article – which was published by Tatarkiewicz a hundred yeas ago (1911) – was the first presentation of the new and interesting interpretation of Plato’s theory of ideas which was inspired by Marburg neo-Kantian school. In Tatarkiewicz’s view the Plato’s philosophy is not some kind of metaphysics but it is generally the theory of knowledge. We can agree this is still unusual approach to Plato and we have a good reason to remind this early Tatarkiewicz’s essay. (shrink)

Newly emerging professions dealing with computing attempt at formulating their own codes of ethics and professional conduct. However, there are widely-known problems with professional ethics – many authors argue that formulating codes of professional ethics causes moral confusion. In this paper, the author examines some main arguments against professional ethics and argues that there are good reasons for developing it. Then he tries to extract those features of professions dealing with computing that may justify a formulation of special codes of (...) professional conduct. He criticises the widely-used concept of the ‚computer professional’ and argues for limiting it to such professions as programmers or operators of computer systems. (shrink)

Moral thinking plays an important role in philosophy of Leszek Kołakowski. The paper examines his ethical position as it was presented in Kołakowski’s writings dealing directly with this subject, against the background of those stances that he opposed. In the scope of the author’s interest is the problem of the persistence of some elements and the development of the position in question. Both Kołakowski’s ethical and metaethical reflection is taken into account. In conclusion, Kołakowski’s position is ascribed to the anti-theoretic (...) current in ethics. (shrink)

Self-esteem and emotional reactivity may be important personality determinants of human functioning in situations of social exposure. In this study, we compared the levels of these personality variables in a group of professional theater actors and a group of professional illusionists with a control group of participants who were neither actors nor illusionists and had no artistic education. We also examined the correlations between emotional reactivity and self-esteem in the three groups. For emotional reactivity, we found (1) very strong evidence (...) that the level is less for magicians than for controls, (2) substantial evidence that the level is less for magicians than for actors, (3) anecdotal evidence that the level is less for actors than for controls, and (4) decisive evidence that the average score is less for males than for females. For self-esteem, we found (1) anecdotal evidence that the level is higher for magicians than for controls, (2) substantial evidence that there is no difference between actors and magicians, (3) anecdotal evidence against a difference between actors and controls, and (4) anecdotal evidence against a difference between males and females. Based on the entire sample we found a moderate correlation between self-esteem and emotional reactivity (r = -.30, p < 0.001). Our results are compatible with the notion that emotional reactivity – as part of the temperament concept – is a factor influencing the choice of an artistic profession. (shrink)

We provide an algorithm for determining a categorial grammar from linguistic data that essentially uses unification of type-schemes assigned to atoms. The algorithm presented here extends an earlier one restricted to rigid categorial grammars, introduced in [4] and [5], by admitting non-rigid outputs. The key innovation is the notion of an optimal unifier, a natural generalization of that of a most general unifier.

We explore how conspiracy beliefs change the effectiveness of gain- vs. loss-framed messages in promoting health-protective behavior. We focused on various recommended COVID-19 protective measures, not only vaccinations but also other preventive (like wearing masks) and detection behaviors (like testing). Our results indicate that conspiracy beliefs moderate the effectiveness of gain vs. loss framing. When participants endorse conspiracy worldviews above the average level, the gain frame may be more effective than the loss frame. In other words, in the loss frame (...) condition, conspiracy beliefs negatively and significantly predicted attitudes toward the behavior recommended. However, in the case of the gain frame, the relationship between conspiracist views and attitudes toward promoted behavior was weaker or even nonsignificant. We also found, although only in the case of one behavior, that when participants' eagerness to look for conspiracies almost does not exist, the loss frame may be a better option than the gain frame. Finally, neither of these effects was mediated by emotional reactance or anxiety. (shrink)

This book challenges the widespread view of Kierkegaard’s idiosyncratic and predominantly religious position on mimesis. -/- Taking mimesis as a crucial conceptual point of reference in reading Kierkegaard, this book offers a nuanced understanding of the relation between aesthetics and religion in his thought. Kaftanski shows how Kierkegaard's dialectical-existential reading of mimesis interlaces aesthetic and religious themes, including the familiar core concepts of imitation, repetition, and admiration as well as the newly arisen notions of affectivity, contagion, and crowd behavior. Kierkegaard’s (...) enduring relevance to the malaises of our own day is firmly established by his classic concern for the meaning of human life informed by reflective meditation on the mimeticorigins of the contemporary age.​ -/- Kierkegaard, Mimesis, and Modernity will be of interest to scholars and advanced students working on Kierkegaard, Continental philosophy, the history of aesthetics, and critical and religious studies.
