Abduction is considered the most powerful, but also the most controversially discussed type of inference. Based on an analysis of Peirce’s retroduction, Lipton’s Inference to the Best Explanation and other theories, a new theory of abduction is proposed. It considers abduction not as intrinsically explanatory but as intrinsically conditional: for a given fact, abduction allows one to infer a fact that implies it. There are three types of abduction: Selective abduction selects an already known conditional whose consequent is the given (...) fact and infers that its antecedent is true. Conditional-creative abduction creates a new conditional in which the given fact is the consequent and a defined fact is the antecedent that implies the given fact. Propositional-conditional-creative abduction assumes that the given fact is implied by a hitherto undefined fact and thus creates a new conditional with a new proposition as antecedent. The execution of abductive inferences is specified by theory-specific patterns. Each pattern consists of a set of rules for both generating and justifying abductive conclusions and covers the complete inference process. Consequently, abductive inferences can be formalised iff the whole pattern can be formalised. The empirical consistency of the proposed theory is demonstrated by a case study of Semmelweis' research on puerperal fever. (shrink)

This experimental study examines individuals’ legitimacy judgments. We develop a model that demonstrates the role of attributed motives and corporate credibility for the evaluation of organizational legitimacy and test this model with an experimental vignette study. Our results show that when a corporate activity creates benefits for the firm—in addition to social benefits—individuals attribute more extrinsic motives. Extrinsic motives are ascribed when a corporation is perceived as being driven by external rewards as opposed to an altruistic commitment to a social (...) cause. Extrinsic motives negatively affect corporate credibility and organizational legitimacy judgments. This article contributes to a better understanding of the complex process of organizational legitimacy judgment by shedding light on the individual’s perspective and expounding the relationship between attributed motives, corporate credibility, and organizational legitimacy.

1. 1. PROGRAM It will be our aim to reconstruct, with precision, certain views which have been traditionally associated with nominalism and to investigate problems arising from these views in the construction of interpreted formal systems. Several such systems are developed in accordance with the demand that the sentences of a system which is acceptable to a nominalist must not imply the existence of any entities other than individuals. Emphasis will be placed on the constructionist method of philosophical analysis. To (...) follow this method is to introduce the central notions of the subject-matter to be investigated into a system governed by exact rules. For example, the constructionist method of investigating the properties of geometric figures may consist in formulating a system of postulates and definitions which, together with the apparatus of formal logic, generates all necessary truths concerning geometric figures. Similarly, a constructionist analysis of the notion of an individual may take the form of an axiomatic theory whose provable assertions are just those which seem essential to the role played by the concept of an individual in system atic contexts. Such axiomatic theories gain in interest if they are supple mented by precise semantical rules specifying the denotation of all terms and the truth conditions of all sentences of the theory.

Previous research has shown that female leaders lead slightly more effective than male leaders. However, women are still underrepresented in higher management. In this study, we seek to contribute to a deeper understanding of this paradox by proposing and testing an innovative model that integrates different research streams on gender and leadership. Specifically, we propose power motivation and transformational leadership as two central yet opposing dynamics that underlie the relation between gender and leadership role occupancy. We tested this model in (...) a sample of 256 employees. Results provided support for the proposed relations. These findings contribute to a more detailed and comprehensive understanding for central dynamics that link gender and leadership role occupancy. Moreover, they provide important insights for interventions that are targeted at reducing the gender gap in leadership. We discuss the theoretical and practical implications of these findings.

Hempel and Oppenheim, in their paper 'The Logic of Explanation', have offered an analysis of the notion of scientific explanation. The present paper advances considerations in the light of which their analysis seems inadequate. In particular, several theorems are proved with roughly the following content: between almost any theory and almost any singular sentence, certain relations of explainability hold.

Friedman’s view on corporate social responsibility is often accused of being incoherent and of setting rather low ethical standards for managers. This paper outlines Friedman’s ethical expectations for corporate executives against the backdrop of the strong emphasis he puts on individual freedom. Doing so reveals that the ethical standards he imposes on managers can be strictly deduced from individual freedom and that these standards involve both deontological norms and the fulfillment of particular stakeholder expectations. These insights illustrate the necessity to (...) reconsider how Friedman’s approach relates to other important normative theories of business ethics. Contrasting Friedman’s approach with stakeholder theory and integrative social contract theory—when considering the importance he assigns to individual freedom—shows how and why these approaches differ. Still, the comparison also highlights striking similarities. This paper contributes to a better understanding of Friedman’s position—which is still one of the most influential approaches in business ethics research—because it enables a differentiated look at its strengths and weaknesses.

P3 is the most prominent of the electrical potentials of the human electroencephalogram that are sensitive to psychological variables. According to the most influential current hypothesis about its psychological significance [E. Donchin's], the “context updating” hypothesis, P3 reflects the updating of working memory. This hypothesis cannot account for relevant portions of the available evidence and it entails some basic contradictions. A more general formulation of this hypothesis is that P3 reflects the updating of expectancies. This version implies that P3-evoking stimuli (...) are initially unexpected but later become expected. This contradiction cannot be resolved within this formulation. The alternative “context closure” hypothesis retains the concept of “strategic information processing” emphasized by the context updating hypothesis. P3s are evoked by events that are awaited when subjects deal with repetitive, highly structured tasks; P3s arise from subjects' combining successive stimuli into larger units. The tasks in which P3s are elicited can accordingly be classified in terms of their respective formal sequences of stimuli. P3 may be a physiological indicator of excess activation being released from perceptual control areas. (shrink)

This book presents a mathematical programming approach to the analysis of production frontiers and efficiency measurement. The authors construct a variety of production frontiers, and by measuring distances to them are able to develop a model of efficient producer behaviour and a taxonomy of possible types of departure from efficiency in various environments. Linear programming is used as an analytical and computational technique in order to accomplish this. The approach developed is then applied to modelling producer behaviour. By focusing on (...) the empirical relevance of production frontiers and distances to them, and applying linear programming techniques to artificial data to illustrate the type of information they can generate, this book provides a unique study in applied production analysis. It will be of interest to scholars and students of economics and operations research, and analysts in business and government. (shrink)

The development of criminal law in the ))Society of risks« proves a transition from liberal and constitutional to social and authoritarian criminallaw as criminal matters are integrated into positive law and gain priority over it. The constitution-oriented model of criminallaw as a complex interrelationship between citizens and the state is re-interpreted to a one-dimensionallegal relationship characterized by punishment being carried out by the state. On the other hand it must be stressed that in the scientific and technological society democracy can (...) no Ionger retain its validity as a form of rule, only as a way of life. Given this precondition criminallaw is aiming at protecting the rights to communication and participation in the society which is based on a basic law. (shrink)

El artículo presenta una visión histórica de la sociedad mapuche y del vínculo “interétnico”; y por otro lado se refiere a los diversos modos de comprensión de “Chile”, para examinar el tema de la existencia o no de una “deuda histórica” con la sociedad mapuche. Remarca que con el advenimiento de la República, los mapuche dejaron de ser vistos como un pueblo o nación y comienzan a ser tratados como chilenos, con lo que se puso fin a la política colonial (...) de los parlamentos. Frente a esto, la sociedad mapuche no logró articular un frente común para encarar el nuevo momento histórico. Agrega que la “Pacificación de la Araucanía” y la “política reduccional” funcionaron no como un proyecto de “inclusión”, sino de “exclusión”. Tras presentar los enfoques de los recientes gobiernos en lo concerniente al tema, y el de los historiadores Gonzalo Vial, Vitale y Pérez, concluye con una propuesta que pasa por separarse de la cultura dominante, y elaborar un política “sensible a las diferencias”.

A fixed-parameter is an algorithm that provides an optimal solution to a combinatorial problem. This research-level text is an application-oriented introduction to the growing and highly topical area of the development and analysis of efficient fixed-parameter algorithms for hard problems. The book is divided into three parts: a broad introduction that provides the general philosophy and motivation; followed by coverage of algorithmic methods developed over the years in fixed-parameter algorithmics forming the core of the book; and a discussion of the (...) essential from parameterized hardness theory with a focus on W [1]-hardness, which parallels NP-hardness, then stating some relations to polynomial-time approximation algorithms, and finishing up with a list of selected case studies to show the wide range of applicability of the presented methodology. Aimed at graduate and research mathematicians, programmers, algorithm designers and computer scientists, the book introduces the basic techniques and results and provides a fresh view on this highly innovative field of algorithmic research.

Statements of the form ''Osorno is in Chile'' were presented in colors that made them easy or difficult to read against a white background and participants judged the truth of the statement. Moderately visible statements were judged as true at chance level, whereas highly visible statements were judged as true significantly above chance level. We conclude that perceptual fluency affects judgments of truth.

In a seminal paper of 1923 on vagueness, Bertrand Russell discussed some of the most important problems concerning the nature of vagueness, its extension within the language, and its relation to truth and logic. The present paper inquires into Russell's theory. The following topics will be analysed and discussed in turn in sections 1?5: Russell's definition of vagueness; his claim that all phrases are vague; his theory of the source of the vagueness in our language; his principles for the transmission (...) of vagueness; and his claim that logic is incompatible with vagueness. This paper is an attempt to give a rational reconstruction of Russell's position as expressed in his paper. Compatible passages in other of his works are also studied. (shrink)

We provide first-order axioms for the theories of finite trees with bounded branching and finite trees with arbitrary (finite) branching. The signature is chosen to express, in a natural way, those properties of trees most relevant to linguistic theories. These axioms provide a foundation for results in linguistics that are based on reasoning formally about such properties. We include some observations on the expressive power of these theories relative to traditional language complexity classes.

Research seeking a scientific foundation for the theory of art appreciation has raised controversies at the intersection of the social and cognitive sciences. Though equally relevant to a scientific inquiry into art appreciation, psychological and historical approaches to art developed independently and lack a common core of theoretical principles. Historicists argue that psychological and brain sciences ignore the fact that artworks are artifacts produced and appreciated in the context of unique historical situations and artistic intentions. After revealing flaws in the (...) psychological approach, we introduce a psycho-historical framework for the science of art appreciation. This framework demonstrates that a science of art appreciation must investigate how appreciators process causal and historical information to classify and explain their psychological responses to art. Expanding on research about the cognition of artifacts, we identify three modes of appreciation: basic exposure to an artwork, the artistic design stance, and artistic understanding. The artistic design stance, a requisite for artistic understanding, is an attitude whereby appreciators develop their sensitivity to art-historical contexts by means of inquiries into the making, authorship, and functions of artworks. We defend and illustrate the psycho-historical framework with an analysis of existing studies on art appreciation in empirical aesthetics. Finally, we argue that the fluency theory of aesthetic pleasure can be amended to meet the requirements of the framework. We conclude that scientists can tackle fundamental questions about the nature and appreciation of art within the psycho-historical framework. (shrink)

The essay operates an itemisation of the three main streams in the history of emotions: the history of individual emotions, the study of the role that emotions have in historical processes, and the reflection on the influence of emotions on history writing. The second part of the article is devoted to the methodological and theoretical status of the study of past emotions. It highlights how many studies in the history of emotions remain heavily conditioned by an idea of culture typical (...) of Western philosophy of history. (shrink)

This article combines findings from cognitive psychology on the role of processing fluency in truth judgments with epistemological theory on justification of belief. We first review evidence that repeated exposure to a statement increases the subjective ease with which that statement is processed. This increased processing fluency, in turn, increases the probability that the statement is judged to be true. The basic question discussed here is whether the use of processing fluency as a cue to truth is epistemically justified. In (...) the present analysis, based on Bayes’ Theorem, we adopt the reliable-process account of justification presented by Goldman (1986) and show that fluency is a reliable cue to truth, under the assumption that the majority of statements one has been exposed to are true. In the final section, we broaden the scope of this analysis and discuss how processing fluency as a potentially universal cue to judged truth may contribute to cultural differences in commonsense beliefs.

Die Studie «Sittlichkeit und Verbrechen bei Hegel» analysiert den Komplex von Sittlichkeit, Verbrechen und Strafe bei Hegel. Sie verfolgt, wie Hegel das Verbrechen vom Standpunkt der Sittlichkeit aus einerseits als etwas davon Abweichendes beurteilt und andererseits die Strafe als die Realisation des Willens des Verbrechers deduzieren will. Dabei werden die logischen Abstraktionen, unter die Hegel das Verbrechen subsumiert, ebenso einer selbständigen Untersuchung unterzogen wie bei der Untersuchung der Sittlichkeit der Standpunkt der Sittlichkeit. Der Abschnitt der Hegelschen «Rechtsphilosophie» «Die bürgerliche Gesellschaft» (...) wird nachgezeichnet als eine Folge jeweils besonders bestimmter Existenzweisen der Begriffsbestimmungen der Idee der Sittlichkeit.
