The use of the axial vector representing a three-dimensional rotation makes the rotation representation much more compact by extending the trigonometric functions to vectorial arguments. Similarly, the pure Lorentz transformations are compactly treated by generalizing a scalar rapidity to a vector quantity in spatial three-dimensional cases and extending hyperbolic functions to vectorial arguments. A calculation of the Wigner rotation simplified by using the extended functions illustrates the fact that the rapidity vector space obeys hyperbolic geometry. New representations bring a Lorentz-invariant (...) fundamental equation of motion corresponding to the Galilei-invariant equation of Newtonian mechanics. (shrink)

Complex systems can be characterized by classes of equivalency of their elements defined according to system specific rules. We propose a generalized preferential attachment model to describe the class size distribution. The model postulates preferential growth of the existing classes and the steady influx of new classes. According to the model, the distribution changes from a pure exponential form for zero influx of new classes to a power law with an exponential cut-off form when the influx of new classes is (...) substantial. Predictions of the model are tested through the analysis of a unique industrial database, which covers both elementary units (products) and classes (markets, firms) in a given industry (pharmaceuticals), covering the entire size distribution. The model's predictions are in good agreement with the data. The paper sheds light on the emergence of the exponent tau approximately 2 observed as a universal feature of many biological, social and economic problems. (shrink)

Background: An external locus of control is associated with poorer psychopathology in individualist cultures, but associations are reported to be weaker in collectivist cultures where an external style is less maladaptive. We investigated the prospective association between externality and psychotic-like experiences and depressive symptoms and compared the strength of associations between a UK and a Japanese cohort.Method: Cross-cultural cohort study of a UK and a Japanese cohort. Externality was assessed using the Children's Nowicki and Strickland Internal, External Scale and DS (...) using the Short Moods and Feelings Questionnaire in both cohorts, PLE were assessed with the Psychosis-Like Experiences Questionnaire, and the Adolescent Psychotic-Like Symptom Screener. Associations were investigated using multivariable regression models and bivariate regression models to compare the strength of associations.Results: Mean externality in both childhood and adolescence was higher in ALSPAC than in the TTC. Childhood externality was associated with PLE in late childhood and adolescence in both cohorts and adolescent externality was associated with PLE in young adulthood in the ALSPAC cohort. There was a more mixed pattern of association between externality and DS scores. There was little evidence of any differences in the strength of associations between externality and different psychopathologies, or between cohorts. In ALSPAC adolescent externality and early adult psychopathology were more strongly associated than childhood externality and adolescent and early adult psychopathology. There was no evidence that change in externality between childhood and adolescence was associated with new onset PLE or DS in early adulthood.Conclusion: An external locus of control is associated with poor mental health regardless of cultural context.

Ainu artists were invited to make “replicas” of traditional Ainu arts held in an important museum collection and describe their choices, process and results. The resulting Ainu aesthetics challenges—and changes—our understanding of aesthetics and the philosophy of art, on four levels: descriptive aesthetics, categorical aesthetics (the categories through which the Ainu understand aesthetic value), implications of these aesthetics for a variety of human activities such as museum practice and daily life, and the implications of the first three for our broader (...) understanding of aesthetics and the philosophy of art. Preliminary analysis of Ainu aesthetics suggests it is interested in it not only as the creation and appreciation of pleasure, but also as the creation and appreciation of meaning, of sacrality, of community, and of knowledge. These latter become especially important given the threats to Ainu culture presented first by incorporation into the Japanese polity and culture and then by modernization and commercialization. Ainu works of art, therefore, carry special significance as means of conveying to current and future generations not only the aesthetic experiences of the past, but their sacred relations, sense of community, and knowledge. This suggests new roles for arts and for museums as they strive to present the works in their full physicality to contemporary audiences, especially those of Ainu artists. (shrink)

This contribution explores the reciprocal links between the organisational transformation of Western European Green parties and the access of some of these parties to national government participation. On the one hand, a series of hypotheses with regard to the possible link between prior organisational adaptation and eventual access to governmental participation are examined. On the other hand, the opposite question is addressed : that of the potential impact of governmental participation on further organisational adaptation. Following both a qualitative and Qualitative (...) Comparative Analysis, one does ultimately identify a link between prior organisational adaptation and eventual access to government, but a much more indirect and contrasted link between governmental participation and further organisational adaptation.

This volume offers a collection of in-depth explorations of pragmatism as a framework for discussions in philosophy of science and metaphysics. Each chapter involves explicit reflection on what it means to be pragmatist, and how to use pragmatism as a guiding framework in addressing topics such as realism, unification, fundamentality, truth, laws, reduction, and more. -/- .

كتاب بحصي يتناول الصراع بين الصوفية والسلفية ويتناول قصة حياة الحلاج وابن الفارض والسهروردي ودواوينهم ويتناول الحب الإلهي عند الصوفية.

An English language translation accompanies the original Greek text of Aristotle's book about the nature of the state, constitutions, revolutions, democracy, and oligarchy.

This is the first complete, one-volume English translation of the ancient Chinese text Xunzi, one of the most extensive, sophisticated, and elegant works in the tradition of Confucian thought. Through essays, poetry, dialogues, and anecdotes, the Xunzi articulates a Confucian perspective on ethics, politics, warfare, language, psychology, human nature, ritual, and music, among other topics. Aimed at general readers and students of Chinese thought, Eric Hutton’s translation makes the full text of this important work more accessible in English than ever (...) before. Named for its purported author, the Xunzi has long been neglected compared to works such as the Analects of Confucius and the Mencius. Yet interest in the Xunzi has grown in recent decades, and the text presents a much more systematic vision of the Confucian ideal than the fragmented sayings of Confucius and Mencius. In one famous, explicit contrast to them, the Xunzi argues that human nature is bad. However, it also allows that people can become good through rituals and institutions established by earlier sages. Indeed, the main purpose of the Xunzi is to urge people to become as good as possible, both for their own sakes and for the sake of peace and order in the world. In this edition, key terms are consistently translated to aid understanding and line numbers are provided for easy reference. Other features include a concise introduction, a timeline of early Chinese history, a list of important names and terms, cross-references, brief explanatory notes, a bibliography, and an index.

This incisive book deals with the use of the criminal law to enforce morality, in particular sexual morality, a subject of particular interest and importance since the publication of the Wolfenden Report in 1957. Professor Hart first considers John Stuart Mill's famous declaration: "The only purpose for which power can be rightfully exercised over any member of a civilized community is to prevent harm to others." During the last hundred years this doctrine has twice been sharply challenged by two great (...) lawyers: Sir James Fitzjames Stephen, the great Victorian judge and historian of the common law, and Lord Devlin, who both argue that the use of the criminal law to enforce morality is justified. The author examines their arguments in some detail, and sets out to demonstrate that they fail to recognize distinction of vital importance for legal and political theory, and that they espouse a conception of the function of legal punishment that few would now share.

A classic exposition of Kant's ethical thought.

Engelhardt invites readers to understand what it means to live in a world after God, where questions of sin and virtue have been replaced with life-and-death-style choices. After God provides a dark prophetic vision. But there is still hope. As Engelhardt argues, In this culture, children now grow up apart from and defended against a recognition of the God Who lives. They are nurtured in a social fabric that is structured so as to avoid a recognition of, much less an (...) encounter with, God. Nevertheless... a traditional Christianity has endured, even though its morality and bioethics have become ever more strongly counter-cultural. The source of this traditional Christian otherness over against the surrounding post-theistic culture lies in the origins of Christianity itself, in the Christianity of the Apostles and the Fathers, namely, in Orthodox Christianity. Against the tenor of the times, disregarding the animus to set traditional Christianity aside, and despite heretics prominent within its fold, Orthodox Christianity remains a light in a world after God. --!

The paper defends the position that phenomenological interviews can provide a rich source of knowledge and that they are in no principled way less reliable or less valid than quantitative or experimental methods in general. It responds to several skeptic objections such as those raised against introspection, those targeting the unreliability of episodic memory, and those claiming that interviews cannot address the psychological, cognitive and biological correlates of experience. It argues that the skeptic must either heed the methodological and epistemological (...) justification of the phenomenological interview provided, or embrace a more fundamental skepticism, a “deep mistrust”, in which scientific discourse can have no recourse to conscious processes as explananda, with ensuing dire consequences for our conception of science.
