Facial perception plays a key role in various social interactions, including formidability assessments. People make relatively accurate inferences about men’s physical strength, aggressiveness, and success in physical confrontations based on facial cues. The physical factors related to the perception of fighting ability and their relative contribution have not been investigated yet, since most existing studies employed only a limited number of threat potential measures or proxies. In the present study, we collected data from Czech Mixed Martial Arts (MMA) fighters regarding (...) their fighting success and physical performance in order to test physical predictors of perceived fighting ability made on the basis of high-fidelity facial photographs. We have also explored the relationship between perceived and actual fighting ability. We created standardized 360° photographs of 44 MMA fighters which were assessed on their perceived fighting ability by 94 raters (46 males). Further, we obtained data regarding their physical characteristics (e.g. age, height, body composition) and performance (MMA score, isometric strength, anaerobic performance, lung capacity). In contrast to previous studies, we did not find any significant links between the actual and perceived fighting ability. The results of a multiple regression analysis have, however, shown that heavier fighters and those with higher anaerobic performance were judged as more successful. Our results suggest that certain physical performance-related characteristics are mirrored in individuals’ faces but assessments of fighting success based on facial cues are not congruent with actual fighting performance.

Spirituality and spiritual well-being are connected with many areas of human life. Thus, especially in secular countries, there is a need for reliable validated instruments for measuring spirituality. The Spiritual Well-Being Scale is among the world’s most often used tools; therefore, the aim of this study was its psychometrical evaluation in the secular environment of the Czech Republic on a nationally representative sample (n = 1797, mean age: 45.9 ± 17.67; 48.6% men). A non-parametric comparison of different sociodemographic groups showed (...) a higher disposition for experiencing spirituality among women, older people, and divorced persons. Based on confirmatory factor analysis, negatively worded items were excluded using a polychoric correlation matrix. The new version of the scale consisting of 11 items had good internal consistency (Cronbach’s α = 0.85; McDonald’s ωt = 0.91). The two-factor model of this shortened version, with factors corresponding to the Religious and the Existential subscales of the Spiritual Well-Being Scale, shows a satisfactory fit with the data, where the loadings of all items ranged from medium to high. Thus, this study offered a new version of the tool, convenient for measuring spiritual well-being in secular conditions. (shrink)

Cet article se donne pour tâche l’examen de la fécondité conceptuelle d’une réduction paradigmatique souvent effectuée par les études en phénoménologie contemporaines de la danse : la réduction du mouvement dansé aux _kinesthèses_ par lesquelles il devrait être immédiatement vécu. Nous entendrons montrer, au contraire, que les kinesthèses ne permettent pas de rendre compte du mouvement vécu parce qu’elles le transforment en un vécu de mouvement demeurant extérieur au sujet qui le vit. Cette critique nous amènera ensuite à repenser conjointement (...) le mouvement dansé comme véritable sujet de la danse et le corps dansant comme déposé par ce mouvement en lequel il est pris.

Mathematical models are an important tool in the development ofsoftware technology, including programming languages and algorithms.During the last few years, a new class of such models has beendeveloped based on the notion of a mathematical game that isespecially well-suited to address the interactions between thecomponents of a system. This paper gives an introduction to thesegame-semantical models of programming languages, concentrating onmotivating the basic intuitions and putting them into context.

Cancers often express hundreds of genes otherwise specific to germ cells, the germline/cancer (GC) genes. Here, we present and discuss the hypothesis that activation of a “germline program” promotes cancer cell malignancy. We do so by proposing four hallmark processes of the germline: meiosis, epigenetic plasticity, migration, and metabolic plasticity. Together, these hallmarks enable replicative immortality of germ cells as well as cancer cells. Especially meiotic genes are frequently expressed in cancer, implying that genes unique to meiosis may play a (...) role in oncogenesis. Because GC genes are not expressed in healthy somatic tissues, they form an appealing source of specific treatment targets with limited side effects besides infertility. Although it is still unclear why germ cell specific genes are so abundantly expressed in cancer, from our hypothesis it follows that the germline's reproductive program is intrinsic to cancer development.

After 1945, Czech philosophy and culture were first introduced to existentialism. First it was the original works of French existentialists (Sartre, Camus, Marcel), later by means of the journal Letters (1947) and Václav Černý (The first book on existentialism, 1948). The acceptance of existentialism in Czech context was not univocal. Besides factual analyses (J. Patočka, V. Navrátil, V. T. Miškovská), existentialism met with criticism and rejection mainly from Marxists and Catholic scholars for its rational weakness, pessimism, helplessness and intellectual decline.

Werner Hamacher, one of the most important and original theorists working in literary criticism and continental philosophy, explores topics at the intersection of philosophy, literary studies and politics.

Since rules - legal, ethical or otherwise - cannot determine their own application, they require persons of flesh and blood to interpret and apply them in concrete cases. Presidents and prime ministers, judges, prosecutors, mediators, leaders of international organizations, and even religious leaders and public intellectuals make decisions on how best to understand rules and how best to apply them. It stands to reason that their character traits influence the sort of decisions they take. This book provides the first systematic (...) framework for discussing global governance in terms of the virtues, and illustrates it with a number of detailed examples of concrete decision-making in specific situations. Virtue in Global Governance combines insights from law, ethics, and global governance studies in developing a unique approach to global governance and international law. (shrink)

The main thesis of this monograph, and its novelty, is the attempt to read Newman's work not only as a defence of the author's life, but as a defence of individual life in general. This reading is done against the background of his profound personalism based on two foundations: truth and responsibility.

Tato práce se zabývá možnými přístupy k etice sexuality, jejich klady i zápory. Etikou sexuality zde není míněno moralizování, stejně tak sexualitou není míněn pouze koitus, pohlavní chování je zde míněno v širším významu tedy včetně rozlehlé oblasti lidského svádění, okolků či otálení. Popsány jsou čtyři klasické přístupy k etice sexuality: tradicionalistický, romantický, marxisticko-feministický a liberální, avšak uvážen je i přístup antinatalistický, který vyplývá z asymetrického argumentu Davida Benatara uveřejněného v jeho práci Nebýt či být. Benatarův antinatalizmus totiž vytváří etiku (...) pohlavního chování, v níž pouze sex, který nevede k rozmnožení, může být morální. I když je tento pátý, antinatalistický přístup značně kontroverzní a zdaleka ne intuitivní, extrémnost jeho pozic se příliš neliší od tradicionalistického pohledu, v němž je morální pouze sex k rozmnožení vedoucí, tyto dva přístupy tak lze postavit do přímé opozice jako dvě krajní možnosti uvažování o etice pohlavního chování. Roli střední cesty v takovém řazení potom zaujme liberální přístup, který jako jediný etiku sexuality nevidí jako etiku odlišnou od jiných lidských činností. (shrink)
