Growth modelling is of interest to scientists in various disciplines. In our article, we will collect 17 models designed for growth modelling, appraise these models and contribute to the discussion of their applicability. The merit of the paper lies in studying the convergence properties of nonlinear regression in selected models. Our studies will be performed mainly concerning the quality of the obtained estimates, which are closely related to the intrinsic curvature of the model according to Bates and Watts. This curvature (...) determines the size of the linearization domains. Only if the initial solution is in this domain, then the convergence of the estimate in nonlinear regression is guaranteed. The primary goal is to design a methodology for selecting a growth model. We will demonstrate fruitfulness of our methodology on the weight measurements of 10 calves under 25 months of age from cowsheds in the village Záluží in the Czech Republic. Estimated parameters of growth curves, sizes of linearization domain, calculated residues and coefficients of determination indices will be the subject of discussion. (shrink)

There exist two conjectures for constraint satisfaction problems of reducts of finitely bounded homogeneous structures: the first one states that tractability of the CSP of such a structure is, when the structure is a model-complete core, equivalent to its polymorphism clone satisfying a certain nontrivial linear identity modulo outer embeddings. The second conjecture, challenging the approach via model-complete cores by reflections, states that tractability is equivalent to the linear identities satisfied by its polymorphisms clone, together with the natural uniformity on (...) it, being nontrivial. We prove that the identities satisfied in the polymorphism clone of a structure allow for conclusions about the orbit growth of its automorphism group, and apply this to show that the two conjectures are equivalent. We contrast this with a counterexample showing that [Formula: see text]-categoricity alone is insufficient to imply the equivalence of the two conditions above in a model-complete core. Taking another approach, we then show how the Ramsey property of a homogeneous structure can be utilized for obtaining a similar equivalence under different conditions. We then prove that any polymorphism of sufficiently large arity which is totally symmetric modulo outer embeddings of a finitely bounded structure can be turned into a nontrivial system of linear identities, and obtain nontrivial linear identities for all tractable cases of reducts of the rational order, the random graph, and the random poset. Finally, we provide a new and short proof, in the language of monoids, of the theorem stating that every [Formula: see text]-categorical structure is homomorphically equivalent to a model-complete core.

Patterns of reproduction associated with extramarital conception are examined using data on non-marital births, marital births occurring during less than 8 months after marriage, and spontaneous and induced abortions experienced by unmarried women. Trends in the incidence and demographic outcomes of conceptions resulting from extramarital coitus are analysed by means of age-specific probabilities of becoming pregnant outside marriage; and of terminating such a pregnancy by abortion, by legitimating it through marriage before confinement, or by having a baby while remaining unmarried. (...) Substantial increases in the proportion of extramaritally conceived pregnancies leading to non-marital births are detected for the period since the late 1980s, and ascribed mainly to rising levels of unmarried cohabitation. The demographic effects of the post-1989 transition from state to market economy are discussed. (shrink)

Význam Thomase Kuhna z hlediska jeho vlivu na další vývoj představ o povaze vědy a konkrétně na vznik tzv. sociologie vědeckého poznání bývá dnes běžně spojován s jeho Strukturou vědeckých revolucí, zatímco jeho starším historickým pracím je v tomto ohledu jen zřídkakdy věnována pozornost. Příspěvek analyzuje právě tyto práce a pokouší se charakterizovat základní metodologické rysy Kuhnova přístupu k dějinám vědy, který je v nich uplatňován. Prostřednictvím jejich porovnání s metodologickými východisky rané sociologie vědeckého poznání se snaží zjistit, nakolik lze (...) již Kuhnovy historické práce považovat za významné ze sociologické perspektivy. Jelikož tyto práce pocházejí z doby, kdy byla historiografie vědy pod výrazným vlivem Alexandra Koyrého, příspěvek zkoumá také metodologická východiska jeho prací, aby bylo možno zjistit, do jaké míry se Kuhnův přístup vymykal standardní poválečné historiogra) i vědy navazující na Koyrého tradici.

Wilhelm Przeczek is a Polish writer who has lived in Karviná, the Czech Republic, since he was born in 1936. He is a member of a Polish minority and he has aimed his literary output at its members and at readers in Poland. Translations into the Czech language are aimed at readers in the Czech Republic. Having made a protest against the intervention of the Warsaw Pact armies into Czechoslovakia in August 1968, W. Przeczek was not allowed to publish and (...) he was dismissed – he had worked as an editor of a Polish paper “Głos Ludu”. In 1970–1977 he worked as an actor, stage director, and dramatic advisor of a puppet show theatre Bajka in Český Těšín, the Czech Republic. In his article, the author deals with poems by W. Przeczek’s on the subject of journeys about Europe. The starting point is local, but a global result. (shrink)

Larry Laudan v článku z roku 1983 označil problém demarkace, tj. rozlišení „vědy" a „pseudovědy", za filosofický pseudoproblém, kterým není třeba se zabývat, a slova „vědecké" a „pseudovědecké" za prázdné pojmy, které můžeme z našeho slovníku zcela vyškrtnout. V předkládané studii zpochybňuji toto Laudanovo stanovisko a předkládám argumenty ve prospěch tvrzení, že 1) rozlišení vědy a pseudovědy představuje důležitý a aktuální problém, kterým je třeba se zabývat, a že 2) možný způsob řešení tohoto problému nabízejí současná sociální studia vědy. Jejich (...) východiskem je pojetí vědy jako „formy života" a pojetí demarkačního kritéria jako proměnlivého souboru charakteristik, který sice nelze jednoznačně definovat, ale přesto jej lze zkoumat, a to prostřednictvím sociologické analýzy vědecké praxe. Mým záměrem je na příkladu několika vzorových studií představit specifika sociologického přístupu z hlediska jeho metodologie i povahy nabízených řešení a zhodnotit jeho možnosti i omezení pro filosofii vědy.

Studie věnuje pozornost problematice demokratizace vědy, v jejímž rámci zaujímá klíčové postavení otázka, v jaké míře a zda vůbec má mít široká veřejnost možnost zasahovat do vědní a výzkumné politiky a participovat na rozhodování v odborných záležitostech. První část studie je věnována představení dvou radikálně odlišných a vzájemně protichůdných pohledů na tuto problematiku, které byly rozpracovány v rámci poválečné filosofie vědy v dílech Michaela Polanyiho a Paula Feyerabenda a v různých podobách spolu soupeří dodnes. Tyto dva pohledy, jež nás staví (...) před volbu mezi odborností na úkor demokracie a demokracií na úkor odbornosti, jsou následně podrobeny kritickému zhodnocení a v opozici k nim je představen alternativní pohled rozvíjený v rámci vědních studií Harrym Collinsem a Robertem Evansem, jenž překračuje nutnost této volby a na základě sociologických výzkumů fenoménu odbornosti nabízí způsob, jak lze odbornost a demokratické hodnoty sloučit dohromady.

Tématem studie je dosud neprobádaná oblast vnějších dějin vzniku sociologie vědeckého poznání. Jejím záměrem je analýza vnějších faktorů, které se podílely na vzniku této disciplíny, a to za účelem nalezení odpovědi na otázku, proč vznikla právě v sedmdesátých letech minulého století na Oddělení pro studium vědy při Edinburské univerzitě a právě v podobě tzv. silného programu sociologie vědění. Skrze postavu zakladatele edinburského Oddělení pro studium vědy C. H. Waddingtona se studie zaměřuje konkrétně na dvě epizody, a to na vznik politicky (...) angažovaného hnutí britských levicových vědců ve třicátých letech prosazujících myšlenku sociální funkce vědy a na politizaci tzv. problému dvou kultur v poválečné Velké Británii, která vedla ke změně britské vědní politiky a k reformám britského systému vzdělání. Závěrečná část studie pak věnuje pozornost individuálním zájmům těch členů edinburského Oddělení pro studium vědy, kteří stáli za bezprostředním vznikem silného programu. (shrink)

Thomas Kuhn ve svých pozdějších pracích ostře napadá tzv. silný program sociologie vědění a důsledně se vůči němu vymezuje. Tato skutečnost je zajímavá z toho důvodu, že představitelé silného programu se naopak ke Kuhnovi otevřeně hlásí a vydatně čerpají z jeho díla, neboť v něm spatřují řadu klíčových myšlenek, které implikují možnost sociologické analýzy vědeckého poznání. Cílem této studie je kriticky přezkoumat Kuhnovu kritiku silného programu a zhodnotit její oprávněnost. V první části je za tímto účelem nejprve rekonstruováno Kuhnovo pojetí (...) silného programu, jež je posléze porovnáno s pracemi jeho zakladatelů Davida Bloora a Barryho Barnese, v nichž je silný program teoreticky rozvíjen. V další části jsou Kuhnovy argumenty proti silnému programu konfrontovány s vybranou historickou studií, v níž je silný program aplikován v praxi. Třetí část pak obrací pozornost ke Kuhnovu vlastnímu pojetí vědy, které je v ní porovnáno se silným programem právě v těch aspektech, jež na něm Kuhn kritizuje. (shrink)

Předmětem této studie je analýza jednoho z aktuálně předkládaných řešení tzv. problému dvou kultur, který roku 1959 formuloval Charles Percy Snow, a to tzv. třetí kultuře, kterou v polovině devadesátých let ve stejnojmenné práci představil John Brockman. Mým záměrem zde bude kriticky zhodnotit Brockmanovo pojetí "třetí kultury" a předložit argumenty ve prospěch tvrzení, že v souvislosti s ním ve skutečnosti nelze hovořit o řešení problému dvou kultur, ale jedná se naopak o názorný doklad přetrvávající existence a aktuálnosti tohoto problému. Pro (...) tyto účely bude v textu využit koncept tzv. obchodních zón (trading zones), který zavádí filosof a historik vědy Peter Galison k popisu a vysvětlení možných způsobů interakce a dorozumění vědců napříč nesouměřitelnými vědeckými disciplínami. Jak se pokusím ukázat, tento koncept lze stejně úspěšně aplikovat i na problematiku komunikace právě mezi přírodními vědami a vědami humanitními. (shrink)

The study of weighted structures is one of the important trends in recent computer science. The aim of the article is to provide a weighted, many-valued version of classical intensional semantics formalised in the framework of higher-order fuzzy logics. We illustrate the apparatus on several variants of fuzzy S5-style modalities. The formalism is applicable to a broad array of weighted intensional notions, including alethic, epistemic, or probabilistic modalities, generalised quantifiers, counterfactual conditionals, dynamic and non-monotonic logics, and some more.

In recent decades there has been growing concern about the combined undesired consequences of rapid economic growth, based on the free market movement, and developments in science and technology. This concern has placed the sustainable development concept on the world's agenda. The notion of sustainability, which originally referred mostly to the environmental consequences of human activities, along with their economic and social aspects, has been discussed not only at the national and the global levels but also in relation to particular (...) sectors of the economy. One such sector is agriculture, which to be sustainable must be ecologically sound, economically viable, and socially responsible. Unless current trade and agricultural policies are geared to creating such a structure, sustainability will be no more than a myth in the industrialized and globalized world, while considerable numbers of people will be left struggling with hunger and poverty. Ethical, fair trade and ecologic agricultural practices, such as organic farming, have been suggested as alternatives to existing practices. However, with their current and potential size, these alternatives cannot compete with existing production and trade systems. But these alternatives nevertheless highlight the main problems of current day free trade and industrialized agriculture structures and their related solutions.This paper reviews the concepts of sustainable development and sustainable agriculture: it raises the question whether the world-wide free market economy is really free, and it considers the undesired consequences of this economy by focusing on the relationship between sustainable agriculture and agriculture-related trade policies.

This article presents an extension of Lewis’ analysis of counterfactuals to a graded framework. Unlike standard graded approaches, which use the probabilistic framework, we employ that of many-valued logics. Our principal goal is to provide an adequate analysis of the main background notion of Lewis’ approach—the one of the similarity of possible worlds. We discuss the requirements imposed on the analysis of counterfactuals by the imprecise character of similarity and concentrate in particular on robustness, i.e., the requirement that small changes (...) in the similarity relation should not significantly change the truth value of the counterfactual in question. Our second motivation is related to the logical analysis of natural language: analyzing counterfactuals in the framework of many-valued logics allows us to extend the analysis to counterfactuals that include vague statements. Unlike previous proposals of this kind in the literature, our approach makes it possible to apply gradedness at various levels of the analysis and hence provide a more detailed account of the phenomenon of vagueness in the context of counterfactuals. Finally, our framework admits a novel way of avoiding the Limit Assumption, keeping the core of Lewis’ truth condition for counterfactuals unchanged. (shrink)

We generalize the notion ofconsequence relationstandard in abstract treatments of logic to accommodate intuitions ofrelevance. The guiding idea follows theuse criterion, according to which in order for some premises to have some conclusion(s) as consequence(s), the premises must each beusedin some way to obtain the conclusion(s). This relevance intuition turns out to require not just a failure of monotonicity, but also a move to considering consequence relations as obtaining betweenmultisets. We motivate and state basic definitions of relevant consequence relations, both (...) in single conclusion (asymmetric) and multiple conclusion (symmetric) settings, as well as derivations and theories, guided by the use intuitions, and prove a number of results indicating that the definitions capture the desired results (at least in many cases).

The cost-effectiveness of 24-hour care makes it a major source of support for elderly people in need of home-based care in Austria. Language barriers, feelings of isolation when living with chronically ill people and a lack of adequate training and quality control create stressful working conditions for 24-hour caregivers in Austria, who mainly come from Slovakia, Hungary and Romania. The challenges not only affect the 24-hour caregivers themselves but also their clients, relatives and registered care agency nurses in care settings. (...) The aim of the qualitative study was to assess user needs in order to develop an app to improve working conditions and quality assurance in 24-hour home-care. The study consisted of guided interviews, focus group and cultural probes and 45 interviewees. The collected data were analyzed using Kuckartz’s method of content structuring qualitative content analysis. The main results show that 24-hour caregivers predominantly require information about common geriatric diseases and the law on 24-hour care. Additionally, medical emergencies can cause insecurities, which creates high interest in professional emergency management skills. Clients and relatives are especially interested in 24-hour caregivers having better German language skills. Care agencies and registered nurses would particularly welcome electronic care documentation to ensure traceability of the activities and measures taken. The study points to the need for a digital tool that would meet demand for an appropriate assistance system for 24-hour home-care that complies with the AAL requirements of the aligned project. Therefore, the intended software solution meets challenges in 24-hour home-care for 24-hour caregivers, persons in need of care, their relatives and professionals involved in the 24-hour care setting.

The rich body of understudied imagery constituting the culture of satire in pre-World War I Paris represents the work of scores of contributing artists, ranging from mockery of manners to biting critique of government policy.

In 1900, Kupka wrote to his friend the Czech poet Josef S. Machar that he would devote himself in (...) future mainly to lithography and graphics as these media are more "democratic".

Recent history reveals a series of rogue traders, jeopardizing their employers’ assets and reputation. There have been instances of unauthorized acting in concert between traders, their supervisors and/or firms’ decision makers and executives, resulting in collusive rogue trading. We explore organizational misbehaviour theory and explain three major collusive rogue trading events at National Australia Bank, JPMorgan with its London Whale and the interest reference rate manipulation/LIBOR scandal through a descriptive model of organizational/structural, individual and group forces. Our model draws (...) conclusions on how banks can set up behavioural risk management and internal control frameworks to mitigate potential collusive rogue trading. (shrink)

The notion of a joint action is a familiar one in the philosophical literature. Moreover, the notion of epistemic action has recently been discussed in the literature. Elsewhere I have suggested that these two notions can be brought together to yield the notion of joint epistemic action and provided a relational individualist analysis of joint epistemic actions. In this article I extend this analysis and show how this extended analysis applies to different kinds of important epistemic institutional phenomena: voting in (...) a democracy; financial benchmarks, e.g. LIBOR rate) and; profiling using computer databases. Each of these institutional mechanisms is important in its own right. Moreover, each is a species of a more widespread generic social form that I refer to as joint institutional mechanisms which, I suggest, are ubiquitous yet somewhat diverse in character. Accordingly, there is a need to distinguish them from the more basic phenomenon of joint action but also to taxonomise them. The latter is a large task to which this article is a first step.

Since the beginning of the twentieth century, abstract art has formed a central stream of modern art. To attain purely aesthetic goals, many avant-garde artists turned painting in particular into a pursuit of breaking off the relations with natural forms. Instead of copying them, they have merely relied on their inner visions. When externalizing these visions directly on the canvas or sheets of paper, the practitioners of abstract art have inadvertently used the phenomenological method and its epoché. In this essay (...) I argue that the philosophies of Kupka and Husserl are largely compatible. This is not because the two use the same terminology, but because they virtually mean and do the same thing in their respective fields. Even where there are significant differences between them, these are not as great as it might at first seem. In the essay’s conclusion I sum up some of the most significant implications their compatible theories have for the philosophy of art and for various theories of art today. (shrink)
