In this paper I present a new theory of propositions, according to which propositions are abstract mathematical objects: well-formed formulas together with models. I distinguish the theory from a number of existing views and explain some of its advantages - chief amongst which are the following. On this view, propositions are unified and intrinsically truth-bearing. They are mind- and language-independent and they are governed by logic. The theory of propositions is ontologically innocent. It makes room for an appropriate interface with formal semantics and it does not enforce an overly fine or overly coarse level of granularity.
The article discusses the issue of multilingual education, which was the subject of discussion and of many scientific studies especially in the late `90s of the last century. Today, due to migration changes, multilanguage education is becoming an important topic again. The authors of the article discuss the most widespread models and concepts of this type of an educational program, which have fund their application in many European countries, such as Germany, Sweden, France and Poland, where due to the current specifications and migration policy, it is appropriate to apply slightly separate models. The element accompanying the formulation of the appropriate education program can be any project whose practical purpose is to raise the awareness among student groups of the importance of the problems and to promote the so-called good practices that have already been developed, among others by Germany.
The article presents aspects of family socializing in terms of evolving models of family life. The changes involve interrelations within the family, consequently its mutual understanding is far from what it used to be. It is the result of, inter alia, the growing number of divorce and separation, the number of single parents raising children, matrimonial decision postponement, restraining from procreation or deciding not to have children, the increase of one person households or informal relationships rising popularity.
This paper will consider some interesting mereological models and, by looking into them carefully, will clarify some important metalogical issues, such as definability, atomicity and decidability. More precisely, this paper will inquire into what kind of subsets can be defined in certain mereological models, what kind of axioms can guarantee that any member is composed of atoms and what kind of axioms are crucial, by regulating the models in a certain way, for an axiomatized mereological theory to be decidable.
Over three decades of research into resilience, this concept has been elaborated in considerable detail, and it now covers a wide range of aspects. Various models are increasingly being applied in order to present the theory of resilience in the clearest possible way. The goal of this paper is to assess the ways in which these models are utilized and to evaluate their benefits and contribution to the development of resilience theory. The article presents various approaches to the use and structure of models (narrative, simplex, complex) and outlines their basic characteristics. The conclusion includes a brief assessment of the benefits of these models and their contribution to the development of resilience theory.
Andrzej Pietruszczak has made a comment on my Claim 1 in his paper entitled “Classical mereology is not elementarily axiomatizable”. His paper is a wonderful exposition of mereological structures and I think his comment is fair. However, the following are some remarks inspired by his comment.
Ever since the discovery of the Predynastic in 1895 by William Matthew Flinders Petrie and James Edward Quibell, great numbers of copper objects have been discovered (fig. 1). However, the study of these objects has been confined to either typological or metallurgical analyses, with seemingly no credence paid to their symbolic aspects (Anfinset 2010; Hassan et al. 2015; Kmošek et al. 2018; Rademakers et al. 2018; Rehren – Pernicka 2014). By combining archaeological and textual data, it is possible today to partly reconstruct the symbolism behind the use of copper objects in funerary context. The aim of this research is to highlight a phenomenon which took place during the transition between the First and the Second Dynasty: the change of the status of copper artefacts found in the tombs. It is possible to see that the size of the objects, and their functionality, changed greatly during this time. Diverse explanations for the phenomenon will be reviewed and a new explanation will be given thanks to a more detailed study of the artefacts and the general context of that time.

The article reveals the models, methods of students’ civic education in the modern higher school. The quintessence and value of the application of role modeling, case-stage, information labyrinth are analysed as well.
Models of vernacular architecture are one of the best ways for the documentation of folk buildings. However, it is necessary to be aware of the fact that those models document the buildings visually, while their construction and material are documented only insufficiently. The research on the models showed that the models are made at more quality levels which differ in the fidelity of imitation of a constructional detail or material used. Even though the models will continue to be a suitable means to document vernacular architecture, it is necessary to replenish them with other documentation methods. The future of the models consists primarily in the presentation of folk buildings.
The proceeding for unfair dismissal claims has been introduced, nearly two years ago by law n. 92 of 2012, to speed up the civil process. However, the reform seems to generate more problems than benefits starting from question of the change of procedure.
Modeling ecosystem services (ES) is an essential tool for the development of strategies that will ensure their future supply, provision and quantification. Given the rapid development in this area of research, a review of the different approaches used to model ES was performed, using an analytical framework based on five criteria for comparing the existing methodological approaches: the types of ES, availability of data sources, spatial scale, types of models used and the possible outcomes of the models. Regulating services were the most commonly modeled, followed by provisioning, cultural, and supporting services. The most frequently used data for modeling were secondary data (already available from scientific literature or data banks). Most studies were performed at the regional or at a global scale. Mechinicist models, based on state and flow equations, were the most commonly used method, but the survey showed a relatively homogeneous distribution of all the identified types of modeling. The synthesis reveals that the majority of studies are based on secondary data, applied at broad scales, without validation techniques, similar to the existing information regarding the mapping of ESs.
The text deals with models of vernacular architecture in collections of the Přelouč City Museum. The models were made by Antonín Pleskot (1909-1980), a native from Přelouč and a today less known author of vernacular architecture ́s models, in connection with the Přelouč Ethnographic Exhibition (1893) at the turn of the 20th century. The contribution also summaries his production. Pleskot produced historical and ethnographic models of different buildings for national heritage institutions and different museums throughout the then Czechoslovakia. His works were exhibited, among other places, in the National Museums in Prague and Bratislava, in the Moravian Museum in Brno, the Silesian Museum in Opava, the South-Bohemian Museum in České Budějovice and in Nitra.Pleskot was a member of the Marold Association of Fine Artists and took part in several exhibitions, including the Exhibition of Folk Art at the Hybernians´ Palace in Prague in 1953.
As human population on Earth has just reached seven billion, food, freshwater and energy supplies are of increasing concern. With fisheries supporting hundreds of millions livelihoods and most of the global capture fisheries production coming from the marine environment, sustainable management of fishing activity based on sound scientific data and reasonable predictions is one of the major issues we face these days. Literature review of the most recent publications on the state of global fisheries was conducted and ten main trends were identified, including expansion of fishing to new ecosystems and species, decline in landings, increase in fishing effort, growth of aquaculture and changes in the abundance and distribution of species. Issues with predicting the future were discussed, as well as usefulness of computer models and possible recovery of the ecosystem.
The paper is focused on the perspective of the common European army. There are several visions about the common European army in the speeches of the highest political representatives of Germany, France, and European Commission. The term European army can be understood in broader or narrower sense. Author proposes theoretical models of the common European army with their possible limitations and opportunities to prove successful. - the European Rapid Reaction Force, the European Battlegroups, single European intergovernmental army. These models differ according to the intensity of defense cooperation and integration of the Member States. The paper is aimed at the individual aspects of the supranational model of the common European army. The role of such common European army is significant in several areas.
Here is a puzzle, which I learned from Terence Parsons in his “True Contradictions” [8]. First Degree Entailment (FDE) is a logic which allows for truth value gaps as well as truth value gluts. If you are agnostic between assigning paradoxical sentences gaps and gluts (and there seems to be no very good reason to prefer gaps over gluts or gluts over gaps if you’re happy with FDE), then this looks no different, in effect, from assigning them a gap value? After all, on both views you end up with a theory that doesn’t commit you to the paradoxical sentence or its negation. How is the fde theory any different from the theory with gaps alone? In this paper, I will present a clear answer to this puzzle – an answer that explains how being agnostic between gaps and gluts is a genuinely different position than admitting gaps alone, by using the formal notion of a bi-theory, and showing that while such positions might agree on what is to be accepted, they differ on what is to be rejected.
The epistemology of models has to face a conundrum: models are often described as highly idealised, and yet they are considered to be vehicles for scientific explanations. Truth-oriented-veritist-conceptions of explanation seem thereby undermined by this contradiction. In this article, I will show how this apparent paradox can be avoided by appealing to the notion of fiction. If fictionalism is often thought to lead to various flavours of instrumentalism, thereby weakening the veritist hopes, the fiction view of models offers a framework much richer than it seems at first sight. To do so, I will call upon the concepts of modality, counterfactual structure and credible worlds. In the end, veritism of explanation and fiction can indeed go hand in hand, but the scope of explanations we can hope to draw from models must be more precisely delineated.
Australian physical education (PE) is experiencing its second national curriculum reform attempt, with schools around the country at various stages of exploration and implementation of the Curriculum for Health and Physical Education (Australian Curriculum and Assessment Authority, 2014). This paper explores some of the challenges in physical education curriculum implementation past and present. The PE teacher is explained as the key architect of curricula at the school level and therefore the challenge of new curriculum implementation is not so much in the ‘rolling out’ of the artefact but in developing the subject expertise of PE teachers to be able to bring to life the curriculum expectation in the situated realities of the everyday pragmatics of the PE teacher. Principally, I argue the PE teacher must see their role as that of educational designer.
The article presents the problems connected with the conceptualization of the contemporary city. These problems result, among other things, from the variability of a city as a research subject and the complexity of urban studies. The new face of the city is formed by six co-occurring trends: the restructuring of the urban economic base, the formation of a global system of world cities, a radical change in urban spatial patterns, changes in the urban social structure, uncontrolled urban sprawl, and changes in the visual form of urban reality. Radical changes in urban studies are determined by three factors: the need to work out new conceptualizations and analytical tools, criticism and revision of the current knowledge as well as generational changes in the community of researchers. A characteristic feature and a development factor of urban studies is the plurality of theoretical and methodological approaches. Model approaches aim at the elimination or alleviation of the negative symptoms of urbanization at the turn of 21th century.
The article presents the concept of Internet crowdsourcing and its socio-economic implications. We present: crowdsourcing definitions and forms (models), possible applications as business model, and e-business strategy in the Information Age, different motivation methods, socio-economic benefits and limitations (risks) related to its development, especially for entrepreneurs and for workers “on-demand”. Special attention has been paid to crowdsourcing market (as a segment of electronic market), which share is estimated and analyzed.
