When seeking to coordinate in a game with imperfect information, it is often relevant for a player to know what other players know. Keeping track of the information acquired in a play of infinite duration may, however, lead to infinite hierarchies of higher-order knowledge. We present a construction that makes explicit which higher-order knowledge is relevant in a game and allows us to describe a class of games that admit coordinated winning strategies with finite memory.

We investigate the expressive power of Parikh's Game Logic interpreted in Kripke structures, and show that the syntactical alternation hierarchy of this logic is strict. This is done by encoding the winning condition for parity games of rank n. It follows that Game Logic is not captured by any finite level of the modal -calculus alternation hierarchy. Moreover, we can conclude that model checking for the -calculus is efficiently solvable iff this is possible for Game Logic.

Dietmar Wetzel unternimmt eine diskurskritisch-vergleichenden Lektüre zweier Theorielinien der neueren Sozialphilosophie: identitäts- versus alteritätsorientierte Konzepte. Das Denken des Ethischen und des Politischen wird dabei anhand einer Beschäftigung mit Schlüsselbegriffen, Konstellationen und Figuren der Gegenwartsgesellschaft thematisch an Gerechtigkeit, Geschlecht, Dritte(m) und Gemeinschaft ausgerichtet. Soziologische Essays, dem Intellektuellen, der Hausfrau, dem Grenzpolizisten und dem Flüchtling gewidmet sind, komplementieren die Analysen. So kann gezeigt werden, daß differenztheoretische Positionen (Lévinas/Derrida) den Begriff der Gerechtigkeit um Aspekte der Fürsorge und der moralischen Gefühle erweitern müssen (...) (Benhabib, Cornell). Da im Übergang der Ich-Anderer-Beziehung zu "ordentlichen Bezügen" das Dritte eine grundlegende Rolle spielt, läßt sich Gemeinschaftsbildung nicht mehr im Sinne natural bzw. religiös begründeter Nachbarschaft (Kommunitarismus), sondern nur als stets neu zu legitimierende und variierende Kultivierung von Andersheit begreifen.

Normative ethics concerns the criticism and justification of morality, law, and other systems of norms. This book develops a normative ethical theory based on individuals and offers a third way beyond the dominant paradigms of Kantianism and Utilitarianism. This theory can assist us in answering concrete ethical questions. The book discusses, for example, the existence of duties to oneself, the permissibility of paternalistic decisions for others, and the status of supererogatory actions. It also considers various problems in bioethics. Key features: (...) Development of a new normative ethical theory Up-to-date overview of the topic Written in clear and comprehensible style Provides answers to concrete ethical problems Also of interest for doctors, lawyers, and economists ".

On the Habermasial Argument of Parasitism. In this article it is argued that throughout Habermas' various treatments of the problem of 'simple imperatives' (threats etc.) one can find a remaining contradiction: namely between identifying them on the one hand, for logical reasons, as the 'unsocial' acts they are (due to their lack of normativity claims). On the other hand, for fitting into sociological descriptions, Habermas tries to rearrange threats etc. within a so-called 'continuum' of all social actions. These difficulties can (...) only be avoided by recognizing the entirely unsocial character of certain ways of acting. This premiss is applied in an alternative analysis of perlocutions and simple imperatives. It leads to the conclusion that for the sake of logical consistency the possibility of ethical (social) ignorance - the Kantian 'evil'? - must be brought into the categorical account of a grammatical analysis of practical statements.

In den 1980er Jahren wurde das Erhabene im Kontext der Debatten um die Postmoderne wiederentdeckt. Dabei konzentrierte man sich auf die Theorien Burkes und Kants, in denen das Schöne dem Erhabenen gegenübergestellt wird. Die Geschichte des Erhabenen in der Frühen Neuzeit dagegen blieb weitgehend im dunkeln. Diese Geschichte wird hier dargestellt, wobei die Studie von der These ausgeht, daß für diesen Zeitraum gerade nicht die Dichotomie von Schönem und Erhabenem zentral ist, sondern die Opposition zweier Modelle des Sublimen selbst: das (...) Erhabene des Ps.-Longin und die Dreistillehre der klassischen Rhetorik. (shrink)

The inclusion of the history and philosophy of science in science teaching is widely accepted, but the actual state of implementation in schools is still poor. This article investigates possible reasons for this discrepancy. The demands science teachers associate with HPS-based teaching play an important role, since these determine teachers’ decisions towards implementing its practices and ideas. We therefore investigate the perceptions of 8 HPS-experienced German middle school physics teachers within and beyond an HPS implementation project. Within focused interviews these (...) teachers describe and evaluate the challenges of planning and conducting HPS-based physics lessons using collaboratively developed HPS teaching materials. The teachers highlight a number of obstacles to the implementation of HPS specific to this approach: finding and adapting HPS teaching material, knowing and using instructional design principles for HPS lessons, presenting history in a motivating way, dealing with students’ problematic ideas about the history of science, conducting open-ended historical classroom investigations in the light of known historical outcomes, using historical investigations to teach modern science concepts, designing assessments to target HPS-specific learning outcomes, and justifying the HPS-approach against curriculum and colleagues. Teachers' perceived demands point out critical aspects of pedagogical content knowledge necessary for confident, comfortable and effective teaching of HPS-based science. They also indicate how HPS teacher education and the design of curricular materials can be improved to make implementing HPS into everyday teaching less demanding. (shrink)

In addition to its two world wars, the rapid decolonization after 1947 has been the most important phenomenon of the 20th century. The two wars led to the decline of the European colonial empires and speeded up decolonization. This process has spawned more than one hundred new nations which in many cases did not exist in this way before. It also fixed territorial boundaries, most of which have remained unaltered ever since. In the course of decolonization constitutions have been made (...) which have also survived unless they have been suspended by military coups. Many of these constitutions bear the stamp of the process of decolonization because they were framed with a view to facilitating the transfer of power. Usually the grant of independence was preceded by various steps in the devolution of power which left their traces in the constitutional documents. Since this devolution implied the prescription of administrative procedures, these constitutional documents often contain a great deal of contingent detail, whereas ‘normal’ constitutions are restricted to statements of fundamental rights and basic principles. This led to ironies of fate such that the Independence of India Act, which subsequently formed the basis of the Indian constitution, is the longest act ever passed by the British Parliament, which is itself based on an unwritten constitution.

The constitutions of the decolonized new nations were marked by the process of the devolution of power. This process had an impact on the agenda setting and arena setting embedded in these constitutions. ‘Agenda’ refers to the conduct of political affairs and ‘arena’ to the delimitation of the powers of Parliament, the design of constituencies, etc. As a special feature, federalism was introduced by several constitutions. It emerged as a device for the gradual devolution of power. In some instances it (...) proved to be a permanent asset (India), in others it was contested (Nigeria) or rejected (Rhodesia). None of the new constitutions contained adequate provisions for the civilian control of the armed forces. The armed forces were simply taken for granted and their potential political role disregarded. But in many new nations political power was soon usurped by the armed forces and constitutional government was suspended. (shrink)

This article improves our understanding of the reasons underlying the intellectual migration of scientists from existing cognitive domains to nascent scientific fields. To that purpose we present, first, a number of findings from the sociology of science that give different insights about scientific migration. We then attempt to bring some of these insights together under the conceptual roof of an actor-based approach linking expected utility and diffusion theory. Intellectual migration is seen as the choice of scientists who decide under uncertainty (...) and on the base of estimations about probabilities, costs, and benefits of the migration. The resulting choice model can be used as a heuristic base for further exploration of the subject. (shrink)

As one tries to grasp love and its images within José Leonilson's production, a multiplicity of aspects and meanings are seen that also relate to Louise Bourgeois's oeuvre in regard to the interest in human relations. Through a comparative approach to both artists' poetics, an understanding is created that love is not a simplistic action and all the words read in or applied to their visual discourse must be considered within a wide range of love in visual and literary images. (...) Keywords: literature and visual arts / love / creativity / Bourgeois, Louise / Leonilson, José / word and image. (shrink)

The article tries to inquire a third way in normative ethics between consequentialism or utilitarianism and deontology or Kantianism. To find such a third way in normative ethics, one has to analyze the elements of these classical theories and to look if they are justified. In this article it is argued that an adequate normative ethics has to contain the following five elements: (1) normative individualism, i. e., the view that in the last instance moral norms and values can only (...) be justified by reference to the individuals concerned, as its basis; (2) consideration of the individuals’ concerns and interests—aims, desires, needs, strivings—insofar as they have a justificatory function; (3) a pluralism of references of these concerns and hence of moral norms and values to all possible elements of actions; (4) the necessity of a principle of aggregation and weighing with regard to these concerns; (5) finally, as a central principle of aggregation and weighing, the principle of relative reference to self and others, operating as a generalizing meta-principle that guides the application of concrete principles and decisions.

The increasing significance of inter- and transdisciplinary research raises the demand for principles with respect to methodology and philosophy of science. The discussion of this question leads to the development of an interdisciplinary research process with two methodic core areas: system integration and inducement of innovation. It will be shown that interdisciplinary research can be understood as a discipline of its own, while its potential of synthesis cannot be declared as a central distinctive feature relative to other disciplines. In fact (...) the developed methodology is firstly aligned analytically, with a focus on the research potential from the area of tension between individual disciplines. This results in an interdisciplinary methodology, generating epistemological progress, which can be applied to complex and cooperation intensive research in academia as well as industry and society.
