With the advent of computers in the experimental labs, dynamic systems have become a new tool for research on problem solving and decision making. A short review of this research is given and the main features of these systems (connectivity and dynamics) are illustrated. To allow systematic approaches to the influential variables in this area, two formal frameworks (linear structural equations and finite state automata) are presented. Besides the formal background, the article sets out how the task demands of system (...) identification and system control can be realised in these environments, and how psychometrically acceptable dependent variables can be derived.

This book does not only attempt to clarify concepts used in the context of dialectical reasoning but also develops an epistemological theory by answering the question: What does it mean to possess a language? The epistemological theory then is used to ground the basis of social science in the logic of our common-sense language. This logic is viewed as more comprehensive than traditional formalized logic, which is viewed as only one though an important aspect of the more general and basic (...) logic of our common-sense language.

Angels are the ultimate stranger. They come from another world and have a special place in the art of the Russian Jewish painter Marc Chagall (1887-1985). In My Life (1923) the young Chagall recalls one memorable night in Saint-Petersburg. Drifting into sleep in the corner of a room (all he could afford) he suddenly saw the ceiling open and a winged being, surrounded by light and blue air, hovered above him before disappearing through the ceiling again.

Das (wie die erhaltenen historischen Belege zeigen) zuerst von Wittgenstein vorgeschlagene Verifikationsprinzip fungiert als Sinnkriterium wie auch als Kriterium der Sinribestimmung. Durch Waismanns Vermittlung wird es in der letzteren Funktion zur ausschließlichen Grundlage von Schlicks Semantik, die jedoch einerseits an ungenügenden Unterscheidungen zwischen Wahrheitsbedingungen, Verifikationsbedmgungen und Verifikationsmethode krankt, andererseits durch eme zu optimistische, die intersubjektive Kontrollierbarkeit entbehrende Sprachauffassung an Überzeugungskraft verliert. Wittgenstems späteres hochkomplexes Bedeutungskonzept, das durch Einbeziehung von Kontext und Äußerungssituation das Verifikationsprinzip zu emem unter mehrerenbedeutungsrelevanten Momenten sprachlicher Äußerungen (...) degradiert, hat Schlick nicht mehr berücksichtigt.

Om samfundsudviklingen i Sverige med udgangspunkt i aktuel forskning inden for sociologi, nationaløkonomi og statsvidenskab, og samtidig et stridsskrift mod nyliberalismen.

The group selection controversy largely focuses on altruism (e.g., Wilson 1983; Lloyd 2001; Shavit 2004; Okasha 2006, 173ff; Borrello 2010; Leigh 2010; Rosas 2010; Hamilton and Dimond in press). Multilevel selection theory is a resolution of this controversy. Whereas kin selection partitions inclusive fitness into direct and indirect components (via influencing the replication of copies of genes in other individuals), multilevel selection considers within-group and between-group components of fitness (Gardner et al. 2011; Lion et al. 2011). Two scenarios of multilevel (...) selection are often distinguished (Damuth and Heisler 1988; Okasha 2006; Pigliucci 2010): (1) group structure only divides individual fitnesses into within- and between-group components (MLS1); and, (2) groups get their own component of fitness and also, in most definitions, a group-level adaptation (MLS2).

Ce livre aborde la philosophie de Plotin sous l'angle des rapports entre la pensée et le langage, analysant le concept d'intellect (Noûs) et les multiples formes du discours dans l'oeuvre pour montrer le lien inextricable entre la teneur métaphysique et la teneur pratique de ce Noûs plotinien.

We study the monoid of primitive recursive functions and investigate a onestep construction of a kind of exact completion, which resembles that of the familiar category of modest sets, except that the partial equivalence relations which serve as objects are recursively enumerable. As usual, these constructions involve the splitting of symmetric idempotents.

The meaning of the concept of fusion is discussed in relation with the works of Payer and those of Van Tieghem. It is pointed out that there is a difference, at the theoretical level, between the concept of fusion congénitale as defined by Payer and the concept of concrescence congénitale formulated by Van Tieghem. The former is inobservable by definition, while the latter deals with intercalary growth. For Van Tieghem, anatomy can prove the existence of fusion, even if we do (...) not see it during ontogenesis.We distinguish three complementary methods for explaining the unions of organs: ontogenetic, typological and phylogenetic. We have attempted, not so much to defend one or other of these methods, as to show that they often invoke very different interpretations for the same morphological phenomena. It is probable that only an analysis of the writings of 19th century botanists will clarify the concept of fusion and more generally the epistemology of plant morphology. (shrink)
