An interview with Wiesław Chrzanowski, a member of the Home Army’s “Gustaw” unit. Chrzanowski recounts the political situation in Europe at the time and the Soviet Union’s and Allies’ stance towards the Warsaw Uprising. He is also critical towards the uprising’s commanders, who launched it without adequate preparation.

First, we prove that the lattice of all structural strengthenings of a given strongly finite consequence operation is both atomic and coatomic, it has finitely many atoms and coatoms, each coatom is strongly finite but atoms are not of this kind — we settle this by constructing a suitable counterexample. Second, we deal with the notions of hereditary: algebraicness, strong finitisticity and finite approximability of a strongly finite consequence operation. Third, we formulate some conditions which tell us when the lattice (...) of all structural strengthenings of a given strongly finite consequence operation is finite, and subsequently we give some applications of them.

The aim of the paper is to prove the result announced by the title.

Research which has been carried out in countries with developed market economies indicates that since the 1980s there has been a systematic increase in wage inequality. As a result, low-wage employment has increased. In recent years, many academic institutions in developed countries have been conducting research into the scale, causes and consequences of low wages. Such research has not as yet been systematically carried out in Poland. This article aims to contribute to the research. Its objective is to establish the (...) scale and causes of low-wage employment in Poland in the last sixteen years. The contents of the article are divided into three parts. The first part is devoted to the methodology of measuring low wages. The second part concerns the frequency of low wages in Poland and other countries with market economies. The third part of the article presents factors influencing the scale of the occurrence of low wages. According to the research, the number of people in low-wage employment in Poland systematically increased in the period from 1989 to 2004. In 2004 this number exceeded 22% of all working people. A similarly high percentage of low-wage employment is found only in Korea, Hungary, Great Britain, the USA and Canada. (shrink)

This paper presents an analysis of learning effectiveness for the courses “Selected issues in visual rehabilitation” and “Ophthalmology and ophthalmic nursing” taught in the years 2009-2011 at the Medical University of Bialystok, Poland. We compared the effectiveness of traditional and distance learning methods; an e-learning platform was implemented experimentally for the purpose of this study. We assessed the usefulness of online learning in terms of organization, knowledge gained and students’ satisfaction with the course. The study was conducted among 75 second (...) year master degree students in the nursing field in the academic years 2009/2010 and 2010/2011. The students were divided into two groups. For the study group of 39 persons, lectures and seminars took place on an e-learning platform, while 36 persons in the control group attended traditional classes. 80% of students in the e-learning group and 89% of students in the traditional group assessed the organization of both forms of courses positively. The fact that the majority of students in both the e-learning and traditional classes gave positive feedback indicates that for both forms there was a high level of content and technical preparedness. The mean scores of the final exam for both courses were 82% in the e-learning group and 79% in the traditional group in the years 2009- 2011. The above results show that both forms of learning are equally effective. (shrink)

We present some equivalent conditions for a quasivariety \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${\mathcal {K}}$$\end{document} of structures to be generated by a single structure. The first such condition, called the embedding property was found by A.I. Mal′tsev in [6]. It says that if \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${{\bf A}, {\bf B} \in \mathcal {K}}$$\end{document} are nontrivial, then there exists \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${{\bf C} \in \mathcal{K}}$$\end{document} (...) such that A and B are embeddable into C. One of our equivalent conditions states that the set of quasi-identities valid in \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${\mathcal{K}}$$\end{document} is closed under a certain Gentzen type rule which is due to J.

Research on natural and artificial brains is proceeding at a rapid pace. However, the understanding of the essence of consciousness has changed slightly over the millennia, and only the last decade has brought some progress to the area. Scientific ideas emerged that the soul could be a product of the material body and that calculating machines could imitate brain processes. However, the authors of this book reject the previously common dualism—the view that the material and spiritual-psychic processes are separate and (...) require a completely different substance as their foundation. -/- Reductive Model of the Conscious Mind is a forward-thinking book wherein the authors identify processes that are the essence of conscious thinking and place them in the imagined, simplified structure of cells able to memorize and transmit information in the form of impulses, which they call neurons. The purpose of the study is to explain the essence of consciousness to the degree of development of natural sciences, because only the latter can find a way to embed the concept of the conscious mind in material brains. The book is divided into three parts. Part 1 works to convince readers that the emergence of consciousness does not require detailed knowledge of the structure and morphology of the brain, with the exception of some specific properties of the neural network structure that the authors attempt to point out. Part 2 proves that the biological structure of many natural brains fulfills the necessary conditions for consciousness and intelligent thinking. Similarly, Part 3 shows the ways in which artificial creatures imitating natural brains can meet these conditions, which gives great hopes for building artificially intelligent beings endowed with consciousness. Covering topics that include cognitive architecture, the embodied mind, and machine learning, this book is ideal for cognitive scientists, philosophers of mind, neuroscientists, psychologists, researchers, academicians, and advanced-level students. The book can also help to focus the research of linguists, neurologists, and biophysicists on the biophysical basis of postulated information processing into knowledge structures. (shrink)

Liking and respect are postulated as two dimensions of interpersonal attitudes. Liking-disliking is an idiosyncratic response which depends mostly on how target persons influence interests and well-being of the attitude holder and is accompanied by beliefs in their communal traits. Respect-disrespect is a socially shared response which depends mostly on the social status of target persons and is accompanied by beliefs in their agency. This Self-interest /status Model of differences between liking and respect was tested in two studies. It was (...) predicted and found that respect responses are socially shared to higher extent than liking responses. (shrink)

Część II pracy objaśnia molekularne podłoże pamięci w oparciu o założenia Neuro-Elektro- Dynamiki postulowanej przez Aura i Yoga. Wskazano na biofizyczne mechanizmy generacji wspomnień, refleksji i odczuć dzięki efatycznym sprzężeniom synaptycznym, spełniającym wymagania indukowania impresjonów Vadakkana. Wykazano, że działanie mechanizmu selekcyjnego WTA może być dobrym modelem opisującym funkcję przełączania uwagi. Wskazano na relacje między pamięcią roboczą, krótkoterminową i trwałą i ich spójność z molekularnymi procesami zapamiętywania i rozpoznawania wzorców. Wskazano, że trwała pamięć epizodyczna wymaga konwersji sekwencji czasowych sygnałów bottom-up do (...) rozkładu przestrzennego tworzącego impresjony dynamiczne. Odwrotna transformacja tych impresjonów umożliwia przypominanie epizodów z przeszłości. Omówiono znaczenie wrodzonych struktur sieci neuronowych zapewniających dziedziczenie zachowań instynktownych. Struktury te nie wykluczają zachowania plastyczności umysłu umożliwiającej efektywne uczenie. (shrink)

W części III przedstawiono motywacje do aktywności autonomicznego systemu inteligentnego w postaci bólu i przyjemności. Wskazano, ze kształtowanie zaawansowanych stanów świadomości takiego systemu wymaga innego rodzaju motywacji w postaci ciekawości i potrzeby zrozumienia. Przedstawiono neuronalne podłoże tych motywacji. Zaproponowano kompleksowy model umysłu świadomego, obejmujący wszystkie poziomy przetwarzania informacji. Przedstawiony model wyjaśnia główne cechy ludzkiej psychiki. Wyjaśnia, jak się tworzy świadomość refleksyjna i samoświadomość, jak umysł formułuje sens i cel swego istnienia, a także sens istnienia otaczającego go świata, w jaki sposób (...) uzyskuje wolną wolę i jak może skutecznie działać dla dobra swojego i dobra świadomości osadzonej w neuronowych polach modelujących. Wyjaśnia, jak potrzeba rozumienia i potrzeba harmonii może tworzyć dobro i inne wartości etyczne. Jakie emocje kierujące umysłem mogą wyzwolić uczucia empatii i altruizmu. Wyjaśnia też, że dla spełnienia tych funkcji, dla nauczenia się wszystkiego, co dobre i moralne, niezbędne jest ciało i możliwość postrzegania oraz oddziaływania na otoczenie. To bezpośredni dowód na konieczność zjednoczenia ciała i ducha aby zaistniały intencjonalnie moralne byty samoświadome. (shrink)

This article shows the organization of distance learning, particularly the idea of b-learning, combining the accomplishment of classes carried on in the traditional way and via computers. The authors present learning activities related to complementary education herein. Some of these course types may be successfully adapted to an e-learning background. The models and structure of the university virtual environment for distance learning are described. These illustrate a new approach to creating a virtual space for medical and technical studies where e-learning (...) courses are created to be used for distance education, which allows students to be taught more effectively. The projected virtual courses for different groups of students ensure individualization of students’ work, which could be a relevant element for creating the shortest path of development of professional competencies. This paper further includes a brief overview of technologies used to build interactive elements into learning mate- rials. The authors present the use of interactive elements in medical education based on examples of certain selected games and animations. (shrink)

The guarded fragment with transitive guards, [GF+TG], is an extension of the guarded fragment of first-order logic, GF, in which certain predicates are required to be transitive, transitive predicate letters appear only in guards of the quantifiers and the equality symbol may appear everywhere. We prove that the decision problem for [GF+TG] is decidable. Moreover, we show that the problem is in 2E. This result is optimal since the satisfiability problem for GF is 2E-complete 1719–1742). We also show that the (...) satisfiability problem for two-variable [GF+TG] is N-hard in contrast to GF with bounded number of variables for which the satisfiability problem is E-complete. (shrink)

The article presents a communication-based analysis of the function of the ‘bez sensu’ [meaningless/ pointless/makes no sense etc.] phraseme. The author discusses the conversational and discursive opportunities for using it. He applies the methodology of communicational grammar, which enables the analysis of communications at the ideational and interactive levels. Within the semantic level, ‘bez sensu’ removes the value of the trivialised semantic standard. In conversations, it is the reaction to scripts which contradict natural logic and the common-sensical cause-and-effect course of (...) things. An important function is the bringing forward of scripts of failure, wastefulness, redundancy, and lack of benefit or expected or actual harm. At the interactive level, the ‘bez sensu’ expression fulfils the function of support for the argumentative power of a communication; it is also a measure of undermining an argumentation – it emphasises the frailty of its premises. In axiological strategies, ‘bez sensu’ is a major component of emotive acts and the building block of the emotional tension between interlocutors. In this instance, it is mostly used to bring forward the experience of a negative emotion. One negative outcome of using the ‘bez sensu’ expression is the introduction distance to interpersonal contact, and in some cases the sense of intellectually debasing the sender of a communication. The article includes several examples of media-based political statements with the ‘bez sensu’ expression, which are used for discrediting political opponents. (shrink)

The categorical dualities presented are: (first) for the category of bi-algebraic lattices that belong to the variety generated by the smallest non-modular lattice with complete (0,1)-lattice homomorphisms as morphisms, and (second) for the category of non-trivial (0,1)-lattices belonging to the same variety with (0,1)-lattice homomorphisms as morphisms. Although the two categories coincide on their finite objects, the presented dualities essentially differ mostly but not only by the fact that the duality for the second category uses topology. Using the presented dualities (...) and some known in the literature results we prove that the Q-lattice of any non-trivial variety of (0,1)-lattices is either a 2-element chain or is uncountable and non-distributive.

Celem pracy jest wskazanie na podstawowe procesy neurologiczne i biofizyczne konstytuuj ące kompleksowy model umysłu świadomego. Przedstawiono zarówno model obliczeniowy działania neuronowych pól tworzących mentalne reprezentacje rzeczywistości, jak i biologiczne koncepcje realizacji tych funkcji mózgu. Wyjaśniono motywacje ludzkiego i zwierzęcego działania. Przedstawiono koncepcje, jak powstaje świadomość oraz jak rozpoznajemy, że jesteśmy świadomi, co objaśnia także problem samoświadomości. Wskazano, że zrozumienie fenomenu świadomości usuwa antynomię teleologicznego i przyczynowego charakteru natury ludzkiej, co niweluje dualizm cielesnego i duchowego charakteru substancji tworzącej nasze umysły. (...) W części pierwszej przedstawiono ograniczenia koncepcji obliczeniowego modelu rozpoznawania poprzez porównywanie i poszukiwanie podobieństw wzorców według Perlovsky’ego oraz wskazano na sposób rozwinięcia tej koncepcji poprzez uwzględnienie morfologii i biologicznych funkcji sieci neuronowej mózgów naturalnych. Pokazano, że neuronowe pola synaptyczne o strukturze hierarchicznej impresjonów w rozumieniu hipotezy Vadakkana mogą spełniać role neuronowych pól modelujących zaangażowanych w gówne procesy psychiczne. Zauważono, że rozszerzony w ten sposób poziom analizy funkcji mózgu w dalszym ciłgu nie pozwala na wyjaśnienie fenomenu świadomości i konieczne jest przeanalizowanie podłoża biochemicznego i molekularnego tych procesów, co zostanie przedstawione w następnych częściach pracy.

We investigate the existence of perfect homogeneous sets for analytic colorings. An analytic coloring of X is an analytic subset of [X]N, where N>1 is a natural number. We define an absolute rank function on trees representing analytic colorings, which gives an upper bound for possible cardinalities of homogeneous sets and which decides whether there exists a perfect homogeneous set. We construct universal σ-compact colorings of any prescribed rank γ<ω1. These colorings consistently contain homogeneous sets of cardinality γ but they (...) do not contain perfect homogeneous sets. As an application, we discuss the so-called defectedness coloring of subsets of Polish linear spaces. (shrink)
