Opis:
This paper addresses an important issue of information of granulation and relationships between the size of information granules and the ensuing robustness aspects. The use of shadowed sets helps identify and quantify absorption properties of set-based information granules. Discussed is also a problem of determining an optimal level of information granulation arising in the presence of noisy data. The study proposes a new architecture of granular computing involving continuous and granulated variables. Numerical examples are also included.

Jednym z zagadnień dyskusyjnych, które spowodowały podział środowiska ekonomistów na zwalczające się naukowo grupy, jest spór o miejsce i pozycję państwa i rynku w funkcjonowaniu gospodarki narodowej. Niektóre poglądy autor naświetlił w artykule.
Among many problems which have emerged during the process of transformation which takes place in our economy, the most important is the dispute about the place and the position of the state and the market, about their "inborn" properties, and about their advantages and disadvantages among others. Assessment made by economists on this issue is totally different. When you take into consideration the authors who stress the value of market economy and its characteristic mechanisms, first of all you should mention the following names: W. Wilczyński, L. Balcerowicz and J. Winiecki. On the other hand, Z. Mikołajewicz, A. Łukaszewicz, the same as P. Bożyk, K. Łaski and J. Pajestka represent a critic standpoint in this field. A similar division is applied when you take into consideration the importance of economic role of the state. Those who would like to lessen its value include: A. Leopold, F. Tomczak, Z. Hockuba, J. Beksiak, C. Józefiak, J. Dąbrowski and J. Winiecki. Less extreme ones, since they clearly see a particular necessity of economic activity of the state includes J. Eysymontt. Whereas S. Kurowski rejects the saying: "The minimum state", and suggests "The sufficient state" as the guideline. And finally - the authors who advertise expansion of the state role in the conditions (what is essential) of system transformation include the following names: M. Klamut, M. Perczyński, H. Sopniewska, B. Winiarski, T. Kowalik, Z. Sadowski, J. Pajestka, A. Łukaszewicz, J. Wierzbołowski, G. Kołodko, J. Kaleta, and W. Sztyber. Thus, the question arises – which is thought over by K. Porwit – what basic requirements should be fulfilled, to bring the opponents together.

Opis:
Basing on analysis of tectonic mesostructures, the structural evolution stages of the Gnieździska Syncline have been determined. The structure represents a typical example of folds occurring in the SW margin of the Holy Cross Mountains. The well-exposed syncline displays a wide variety of structures, including: shear and extension joints, stylolites, cleavage, strike-slip and dip-slip faults as well as master joints. Tectonic structures resulting from flexural slip indicate that the Gnieździska Syncline developed as a flexural-slip fold as a result of horizontal NE-SW compression. The subsequent deformation phase included mesostructures pointing to the increasing activity of a nearby Gnieździska-Wola Morawiecka dextral strike-slip fault of regional extent. In the terminal phase of the post-kinematic uplift of the Holy Cross Mountains, T joints and master joints appeared.

Opis:
Secondary isotope effects for carbonyl addition reactions of methyl thioacetate, acetone and acetaldehyde have been calculated by ab initio quantum mechanical methods in an effort to interpret measured beta-deuterium isotope effects on acetylcholinesterase- catalyzed hydrolysis of acetylthiocholine. The calculated beta-deuterium isotope effect for equilibrium addition of methanol to methyl thioacetate is D3Keq = 0.965, and the corresponding effect for addition of methoxide ion to methyl thioacetate wherein three waters are hydrogen bonded to the carbonyl oxyanion is D3Keq = 1.086. Neither of these calculated isotope effects is as inverse as the experimental beta-deuterium isotope effect for acetylcholinesterase-catalyzed hydrolysis of acetylthiocholine, D3kE = 0.90š0.03. Structural comparisons show that the water-solvated methoxide adduct of methyl thioacetate is more expanded than is the neutral methanol addition adduct, and suggest that the degree to which the isotope effect is inverse (i.e. less than) is inversely correlated to the degree of expansion of the adduct. A similar correlation of beta-deuterium and beta-deuterium secondary isotope effects with the degree of expansion of the adducts is found for equilibrium additions of methanol and methoxide ion to acetaldehyde. These computational results suggest that the markedly inverse beta-deuterium isotope effect for the acetylcholinesterase reaction arises from enzymic compression of the transition state.

Opis:
The process of modelling and developing commonality and variability for system families should be supported by suitable methods and notations. The object-oriented methods and their notations, which are used at present, focus on the development of a single system at a time. In this paper we analyse feature models as a representation of the common parts and variants contained in a system family, and propose using a feature diagram as a basic representation of commonality, variability and dependencies. We examine various approaches to customizing the standard modelling language UML to model system families and propose how to extend the UML for the purposes of modelling variants in object-oriented analysis and design techniques. We recommend the use of UML standard lightweight extensibility mechanisms (stereotypes combined with tagged values) without changing the UML metamodel. This enables us to join the advantages of feature models with UML and provides the traceability of a concept throughout system development. An application of lightweight UML extension mechanisms allows the existing standard UML modelling tools to be used without any adaptations. An example of an application illustrates our approach.

Opis:
While a genuine abundance of biomedical data available nowadays becomes a genuine blessing, it also posses a lot of challenges. The two fundamental and commonly occurring directions in data analysis deal with its supervised or unsupervised pursuits. Our conjecture is that in the area of biomedical data processing and understanding where we encounter a genuine diversity of patterns, problem descriptions and design objectives, this type of dichotomy is neither ideal nor the most productive. In particular, the limitations of such taxonomy become profoundly evident in the context of unsupervised learning. Clustering (being usually regarded as a synonym of unsupervised data analysis) is aimed at determining a structure in a data set by optimizing a given partition criterion. In this sense, a structure emerges (becomes formed) without a direct intervention of the user. While the underlying concept looks appealing, there are numerous sources of domain knowledge that could be effectively incorporated into clustering mechanisms and subsequently help navigate throughout large data spaces. In unsupervised learning, this unified treatment of data and domain knowledge leads to the general concept of what could be coined as knowledge-based clustering. In this study, we discuss the underlying principles of this paradigm and present its various methodological and algorithmic facets. In particular, we elaborate on the main issues of incorporating domain knowledge into the clustering environment such as (a) partial labelling, (b) referential labelling (including proximity and entropy constraints), (c) usage of conditional (navigational) variables, (d) exploitation of external structure. Presented are also concepts of stepwise clustering in which the structure of data is revealed via a series of refinements of existing domain granular information.

effects of manipulation
Opis:
The analyses based on research show a complex problem of the reception of the media by the academic youth. They focus on how the youth understand and discover the complicated phenomenon of manipulation, a phenomenon that is relatively common in the contemporary mass media. It has been stated that the academic youth from Pêock has a very good knowledge about the media and a relatively deep insight in their manipulation. The students devote much to television, and clearly less time to the radio, and relatively little time to reading periodicals. It is a positive fact the subjects in principle adopt a conscious attitude towards the mass media and select among various media. The academic youth are well aware of the phenomenon of manipulation in the Polish media. It is especially present in television programmes. The research and analyses prove that female students know more about manipulation. They can also give better examples of manipulation and are more sensitive to the fact of various techniques and strategies of manipulation in the Polish media. Female students decisively more often than male students notice the use of manipulation especially in television and radio programmes. They are considerably more capable of decoding the technique of suggestion, falsification of reality and ingratiation - particularly, when it comes to propagate political views and influence religious attitudes. Female students are more aware of various manipulatory suggestions and attach greater effectiveness to them, especially the strategy of deriding religious values or the sensation-music-sex strategy are used. Analysing the relations between the type of university and the frequency of discovering manipulation in the media it has been found that students studying the humanities are better oriented in the phenomenon under consideration than technical university students. It is worth noting that in particular students from the Academy of Catholic Theology have a clearly higher level of media awareness. This is so both with regards to the knowledge about the mass media and the understanding of the essence of manipulation in the media, its application, any threats, and its negative effects. The analyses make us postulate a further research into the media-related problems. It goes without saying that there is an urgent need to take up educative activities to incur a habit by which we know how to use the media. These activities should be taken up by such educative institutions as the family, the school, religious communities, universities, and the mass media. The point is to be educated for a proper, i.e. such that helps in a versatile development of the person, usage of the media. One should teach recipients to selective in their choice of the rich variety that the media offer, in other words to find useful and beneficial programmes. It is necessary to expose the media contents and develop intelligent attitudes among the users of the mass media. Pedagogy is obliged to form reflective attitudes towards the media, so that the recipient could recognise the beneficial aspects of the media and reject what is worthless, good for thing, stultifying, mediocre, or even harmful.

Opis:
In the conceptual design of an ecological floating dock, has been assumed to be applied a roof system consisted of six movable segments whose aim is to shelter dock’s working space from environmental influence. The dock has to be also equipped with a gantry crane. Each of the devices is fitted with a traction system whose drive is the subject of this paper. The driving system consisted of synchronous electric motors with external frequency control of their rotational speed, is proposed. Such system may ensure the same rotational speed at both supports, unambiguously determined by voltage frequency and independent of load. The solution could make it possible to avoid dangerous skewing displacements of the structures on rail tracks during service. Additionally, a simplified procedure of determining the main loads necessary for calculation and selection of the devices and traction systems is also presented.

Opis:
Szeroko definiowani rolnicy wraz z emerytami rolnymi stanowią liczną, choć trudną do precyzyjnego określenia, zbiorowość. Jest ona bardzo zróżnicowana, lecz liczebnie dominują w niej quasi-chłopi, drobni, najczęściej nieprowadzący towarowej produkcji, rolnicy. Zbiorowość ta ma wiele negatywnych charakterystyk ekonomicznych, społecznych i psychologicznych. Specyficzne są także jej polityczne zachowania, jej członkowie zwracają się ku partiom agrarno-populistycznym. Autorka, odwołując się do sformułowanych wcześniej koncepcji „blokowania rozwoju” i „moderowania zmian”, analizuje polityczne mechanizmy spowalniania przemian, uruchamiane przez szeroko rozumianą zbiorowość rolników.
Polish farmers are hardly definable social group. It is a diversified population dominated (in numbers) by “quasi-farmers” – running small farms for own consumption, not selling their products at the market. This category has many negative, economic, social and psychological features. Their political choices are often to support the populist, agricultural parties. The author, referring to the concepts of “blocking development” and “moderating the changes”, describes the political mechanisms of slowing down the reforms applied by the (broadly considered) Polish farmers.
