It has been recently shown [4] that the lattice effect algebras can be treated as a subvariety of the variety of so-called basic algebras. The open problem whether all subdirectly irreducible distributive lattice effect algebras are just subdirectly irreducible MV-chains and the horizontal sum of two 3-element chains is in the paper transferred into a more tractable one. We prove that modulo distributive lattice effect algebras, the variety generated by MV-algebras and is definable by three simple identities and the problem (...) now is to check if these identities are satisfied by all distributive lattice effect algebras or not.

The paper explores the possibilities of using applied qualitative research to help to achieve changes in the context of education. It presents three case studies: an evaluation of an educational software package which may be implemented nationally; an assessment of the impact of a 1:1 Technology Rich Learning Environment experimental project conducted in two Slovak elementary schools; and international comparative research on the curricula of psychology courses in secondary schools. The authors ask three questions: 1. does qualitative research have the (...) potential/resources/capacity to guide us in the process of making policy related decisions? 2. Does it have enough credibility in the eyes of the consumers—whether these are decision-makers themselves or a wider community that often plays a role in public decisions? 3. Could this type of work still count as academic inquiry? The discussion evolves around the reflection of the position of researchers in this type of research design, and the authors conclude that applied qualitative research could be the source of solid evidence for making decisions related to education—although this evidence is different to that provided by quantitative research.

Several investigations in probability theory and the theory of expert systems show that it is important to search for some reasonable generalizations of fuzzy logics (e.g. Łukasiewicz, Gödel or product logic) having a non-associative conjunction. In the present paper, we offer a non-associative fuzzy logic L CBA having as an equivalent algebraic semantics lattices with section antitone involutions satisfying the contraposition law, so-called commutative basic algebras. The class (variety) CBA of commutative basic algebras was intensively studied in several recent papers (...) and includes the class of MV-algebras. We show that the logic L CBA is very close to the Łukasiewicz one, both having the same finite models, and can be understood as its non-associative generalization. (shrink)

Adolescents, as active online searchers, have easy access to health information. Much health information they encounter online is of poor quality and even contains potentially harmful health information. The ability to identify the quality of health messages disseminated via online technologies is needed in terms of health attitudes and behaviors. This study aims to understand how different ways of editing health-related messages affect their credibility among adolescents and what impact this may have on the content or format of health information. (...) The sample consisted of 300 secondary school students. To examine the effects of manipulating editorial elements, we used seven short messages about the health-promoting effects of different fruits and vegetables. Participants were then asked to rate the message’s trustworthiness with a single question. We calculated second-order variable sensitivity as the derivative of the trustworthiness of a fake message from the trustworthiness of a true neutral message. We also controlled for participants’ scientific reasoning, cognitive reflection, and media literacy. Adolescents were able to distinguish overtly fake health messages from true health messages. True messages with and without editorial elements were perceived as equally trustworthy, except for news with clickbait headlines, which were less trustworthy than other true messages. The results were also the same when scientific reasoning, analytical reasoning, and media literacy were considered. Adolescents should be well trained to recognize online health messages with editorial elements characteristic of low-quality content. They should also be trained on how to evaluate these messages.

H.m. is the science of the most general laws and root forces in the development of human society. H.m. came into being in the mid-19th century. Its creators were the leaders and ideologists of the working class: Marx and Engels. In founding a new philosophical world view, dialectical materialsm, Marx and Engels applied it to cognition of society, its history and life.

The purpose of this article is to consider critically the humanistic potential of Olympism. We consider the concepts ‘human’ and ‘humanism’ from an existential perspective. Existentialism argues that human beings exist in a state of freedom. Freedom, as the basis of being human, holds a human fully responsible for his or her own existence. This responsibility assumes an active mode of behaviour, predicated on human effort. It can also include the making of specific artifacts such as creating creations. According to (...) Mamardashvili, creating creations are unique cultural mechanisms that remain in the boundaries of morality, beauty, thought and so on, adding quality to human existence. The article argues that the desire to be fulfilled as a human being is the moral basis to which Olympism directs Olympic athletes. Moreover, Olympism expresses the human’s need of self-overcoming, constant self-perfection which is necessary aspect of the humanity. Thus, the humanistic potential of Olympism lies in the fact that it allows for the creative space in sport which is itself a place for human realization. Therefore, Olympism can be characterized as opera operans, creating creation. (shrink)
