The Czech dissident movement included thinkers who searched for a morally pure, parallel polis, and who felt comfortable within its isolation. The philosophers of Charter 77 (Jan Patočka and Ladislav Hejdánek especially), by contrast, rejected the idea of being morally superior to their opponents. It is interesting to consider where Václav Havel stands at this crossroads. Havel very much cooperated with the above-mentioned philosophers and was inspired by them in his own writing and agency. On the other hand, Havel undoubtedly performed a certain moral-existential concept of dissent. In this paper I examine Havel’s existential concept. In particular, after distinguishing between two existential approaches in Havel’s writings, I analyse two fundamental philosophical critiques of Havel in the work of Ladislav Hejdánek. According to Hejdánek, Havel 1) identifies intellectuals with non-politicians, i.e. he is governed by the incorrect dualism of the political versus the non-political, and 2) is self-focused and moralising, i.e. he keeps too much within his own self (subjectivity) and “a given” (existent, objective) world. Given this critique, I will systematise Hejdánek’s objections and suggested solutions. In the first case, I see the solution in a more detailed distinction: we should distinguish between politics and non-politics (intellectuals) but also non-political politics. In the second case, we should look for the essence (focal point) of man not in his morality but outside it: man should orient himself “out of his self”.
This paper discusses the strengths and weaknesses of pan-European datasets, in particular ECHP and EU-SILC, for research in housing. Although ‘housing’ is a complex topic when studied from a European comparative perspective, I argue that there is no inherent reason why housing should be less amenable to cross-national research than other equally complex topics in comparative social science research, such as research into family change and stability, or the impact of educational systems on social stratification. Given appropriate theory, conceptualisation and contextualisation, along with strong methodologies, meaningful and informative research in housing with ECHP and EU-SILC are possible. There are however a number of limitations, which are mainly related to the fact that both datasets are geared towards the ‘production’ of a ‘system of social indicators’ informing European and national governments. Because of these limitations, ECHP and in particular EU-SILC are less attractive and less useful for academic research then they could potentially be.
Since Antiquity, logic has always enjoyed a status of something crucially important, because it shows us how to reason, if we are to reason correctly. Yet the twentieth century fostered an unprecedented boost in logical studies and delivered a wealth of results, most of which are not only not understandable by non-specialists, but their very connection with the original agenda of logic is far from clear. In this paper, I survey how the achievements of modern logic are construed by non-specialists and subject their construals to critical scrutiny. I argue that logic cannot be taken as a theory of the limits of our world and that its prima facie most plausible construal as a theory of reasoning is too unclear to be taken at face value. I argue that the viable construal of logic takes it to be explicative of the constitutive (rather than strategic) rules of reasoning, not of the rules that tell us how to reason, but rather of rules that make up the tools with which (or in terms of which) we reason., Od starověku se logika vždy těšila stavu něčeho zásadně důležitého, protože nám ukazuje, jak rozumět, pokud máme správně rozumět. Dvacáté století však podpořilo bezprecedentní oživení v logických studiích a přineslo mnoho výsledků, z nichž většina není nejen srozumitelná pro nešpecializované odborníky, ale jejich samotné spojení s původní logikou logiky není zdaleka jasné. V tomto příspěvku zkoumám, jak jsou úspěchy moderní logiky konstruovány nešpecializovanými odborníky a podřizují jejich konstrukty kritické kontrole. Domnívám se, že logiku nelze považovat za teorii hranic našeho světa a její prima facienejspolehlivější konstrukční jako teorie uvažování je příliš nejasná, aby mohla být přijata v nominální hodnotě. Domnívám se, že životaschopná konstrukce logiky má za to, že je vysvětlující konstitutivní (spíše než strategická) pravidla uvažování, nikoli pravidla, která nám říkají, jak rozumět, ale spíše pravidla, která tvoří nástroje, s nimiž (nebo v podmínky) rozumíme., and Jaroslav Peregrin
Starling’s original definition of a hormone from 1905 was “a hormone is a substance produced by glands with internal secretion, which serve to carry signals through the blood to target organs”. Today, this definition is understood to be lacking, but newer definitions also do not encompass the entire meaning of hormones as specific carriers of information. One main problem is that there is no delineation between hormones and other signaling molecules such as cytokines, growth factors or autacoid compounds. It seems that a precise definition is not even possible, since some cytokines and growth factors, such as the cytokines erythropoietin, lipocalin-2 and asprosin or fibroblast growth factor 23, act as hormones under certain conditions., Luboslav Stárka, Michaela Dušková., and Obsahuje bibliografii
The aim of this study was to check what decide about breeding success in red- backed shrike Lanius collurio: nest-site concealment or parent’s aggressive behaviour. The study was carried out in eastern Poland in 1999–2003, on study plot consisted of 855 ha of extensively agricultural landscape. The effect of nest site concealment and defence of brood by parents on breeding success was determined. In observations only natural nests were used. During the two of 10 days periods after commence of egg laying, no effect of index nest concealment and index of parents aggressiveness was observed. However, in first seven days of life of nestlings, was noticed that breeding success was depended on aggressiveness of parents, in relation to index nest concealment. The results showed behavior (aggression) as an important factor in breeding success of the red-backed shrike.
