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.

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)
