A theoretical analysis of the concept of lifetime and mean life of unstable elementary particles is presented. New analytic formulas for lifetime and mean life as a function of decay width Γ and the mass of unstable particle are derived for Breit-Wigner and Matthews-Salam energy distributions. It is demonstrated that, for unstable particles with a larger width or decay energy threshold, the deviation from the generally accepted mean life τ m =Γ −1 is significant. The behavior of the decay law (...) P(t) for small times is analyzed, and it is shown that the Breit-Wigner distribution violates the condition P(t = 0) = 0, whereas the Matthews-Salam distribution satisfies it. (shrink)

Children with developmental dyslexia and at its risk have difficulties in the acquisition of foreign languages, especially non-transparent English. The problems of such pupils concern various aspects of the language system but in particular relate to the ability to read and spell. The research literature dedicated to effective preventative methods and dyslexia treatment suggests that both children with dyslexia and at its risk need phonological awareness training and multi-sensory learning. It is also known that prevention and early treatment is more (...) effective than therapeutic intervention used in older students. Experts in foreign language acquisition recommend that children have contact with longer oral texts and live language. A recently-published report on the methods of English language teaching in Polish primary schools shows that the lessons conducted there do not realise the majority of the aforementioned recommendations. As a consequence, they do not serve any pupils including those with dyslexia and at its risk. A method which meets most of the demands mentioned above is “The Good Start Method for English”. It is a new program of teaching the English language designed for five to seven-year-olds, which at the same time ensures support for the psychomotor development of children, leading to acceleration in learning progress.

The problem of legal normativity is one the most controversial issues in the philosophy of law. It was already a subject of heated debate in the 19th century and, over the last 100 years, the study of normativity has taken many shapes and forms, from Kelsen's dualism, through the reductionism proposed by legal realists, to some nihilistic stances. In recent years, there has been a renewed interest in the problems surrounding the concept of law's normativity, and this collection is seen (...) as a contribution to that debate. The book will be of interest to lawyers and philosophers, both at the graduate and professional levels. (shrink)

Jerzy Perzanowski s ideas were based on an original blend of logic and ontology in what he called onto/logic, where the slash is meant to suggest a quotient of ontology by logic. Perzanowski began as a logician, his early works being on modal logic, then gradually shifted his interest to logical philosophy, meaning not so much philosophy of logic as philosophy informed by logic. Perzanowski was a rare breed of analytical philosopher who thought that a philosophical theory of everything (...) was worthwhile. In this systematic spirit, he began with method. He presented his method of total analysis and synthesis quite simply: reduce the object of research to its simplest possible constituents, and then combine them in some way. Better still, combine them in every possible way, thereby producing a space of possibilities analogous to (and in certain cases identical with) the logical space. Thus, analysis and synthesis differ from a trivial disassembly and reassembly.". (shrink)

The Normative Mind addresses philosophical and scientific issues connected with rule-following and decision-making from the perspectives of philosophy and various sciences. The book examines the diverse relations with rule-following behavior of such phenomena as cognitive control, emotions, decision-making heuristics, and creativity. The contributions-by philosophers, psychologists, and neuroscientists-also concern the problem of normativity as it is present in logic, moral epistemology, and rational choice theory. Furthermore, the roles of evolution and of neural processes for the emergence of rule-following behavior are analyzed. (...) [Subject: Philosophy, Psychology, Cognitive Science]. (shrink)

Jerzy Franczak comprehensively presents Jacques Rancière's thought by emphasizing the relations between politics and literature. The detailed analysis considers the context of modern aesthetics and political philosophy, which is why the book introduces further protagonists, such as Louis Althusser, Michel Foucault, Pierre Bourdieu, or Jean-François Lyotard. Franczak first reconstructs Rancière's original philosophy of literature so as to then immediately apply it in readings of select world literature masterpieces by Gustav Flaubert, Max Jacob, Bertold Brecht, Vladimir Nabokov, and Philip Roth.

CONTENTS:--Reichenbach, H. Elementy logiki formalnej (fragmenty).--Wybrane studia z semiotyki logicznej.

The contributions in this book deal with the issue of normativity from various academic and scientific perspectives. The reader will learn how phenomena - such as norms, morality, and rule-following - are described and explained in philosophy, biology, psychology, linguistics, and neuroscience. In addition, a discussion of the naturalistic fallacy, from philosophical and ethical perspectives, is included.
