In chapter VII of On Interpretation, Aristotle alters a system of three pairs of natural contradictory propositions, in that he ignores the pair where two natural universals Men are white, Men are not white oppose each other contradictorily. This alteration has serious consequences: the two natural pairs, which Aristotle considers exclusively: All men are white versus Some men are not white and Some men are white versus No man is white are illegitimately identified to the two pairs of logical contradictories (...) constituting the logical square: A versus 0 and I versus E respectively. Thus, the level of natural language and that of logic are confused. The unfortunate Aristotelian alteration is concealed by the translation of propositions known as indeterminates. To translate these, which, semantically, are particulars, all scholars, except for P.Gohlke, employ the two natural universals excluded by the master! The work of I. Pollak, published in Leipzig in 1913, reveals the origin of this nearly universal translation mistake: the Arabic version upon which AI-Farabi unfortunately bases his comment. In adding the vertices Y and U to the four ones of the square, the logical hexagon of Robert Blanche allows for the understanding of the manner in which the logical system and the natural system are linked.

This paper first provides a brief survey of a possibilistic handling of default rules. A set of default rules of the form, "generally, from α deduce β", is viewed as the family of possibility distributions satisfying constraints expressing that the situation where α and β is true has a greater plausibility than the one where α and ⇁β is true. When considering only the subset of linear possibility distributions, the well-known System P of postulates proposed by Kraus, Lehmann and Magidor, (...) has been obtained. We also present two rational extensions: one based on the minimum specificity principle and the other is based on the lexicographic ordering. The second part of the paper presents an empirical study of three desirable properties for a consequence relation that capture default reasoning: Rationality, Property Inheritance and Ambiguity Preservation. An experiment is conducted to investigate 13 patterns of inference for the test of these properties. Our experimental apparatus confirms previous results on the relevance of System P, and enforces the psychological relevance of the studied properties. (shrink)

Downsizing remains a topic of great interest to both academics and practitioners. Yet, the impact of layoff decisions on perceptions of corporate social responsibility (CSR) has hardly been studied. We examine the impact of responsibility of business leaders making these layoff decisions, and characteristics of the downsizing implementation on convergence and divergence in (1) CSR perceptions, (2) victims’ perceptions of fairness, and (3) survivor commitment, in four countries. Using an experimental design, sixteen scenarios were distributed to (1) 163 managers in (...) Estonia, (2) 152 MBA students in India and 125 MBA students in France, and (3) 186 (non-traditional) undergraduate students in the USA. Results suggest that when top managers are attributed with the responsibility for downsizing, the resulting perceptions of CSR are negative. A similar pattern of results is obtained for victims’ perceptions of fairness and survivor commitment. In addition, although there are differences in effect-size based on differences in power distance, these results hold good (are similar) across the four countries, from four different society clusters. We discuss implications, limitations, and future research directions. (shrink)

:Statisticians have proposed formal techniques for evaluation of treatments, often in the context of models that do not explicitly specify how treatments are generated. Under such procedures they run the risk of attributing causation in settings where the implementation neutrality condition required for causal interpretation of parameter estimates is not satisfied. When treatment assignments are explicitly modelled, as economists recommend, these issues can be formally analysed, and the existence of implementation neutrality, and therefore quantifiable causation, can be determined. Examples are (...) given. (shrink)

:The most basic question one can ask of a model is ‘What is the effect on variable y2 of variable y1?’ Causation is ‘implementation neutral’ when all interventions on external variables that lead to a given change in y1 have the same effect on y2, so that the effect of y1 on y2 is defined unambiguously. Familiar ideas of causal analysis do not apply when causation is implementation neutral. For example, a cause variable cannot be linked to an effect variable (...) by both a direct path and a distinct indirect path. Discussion of empirical aspects of implementation neutrality leads to further unexpected results, such as that if one variable causes another the coefficient representing that causal link is always identified.

Financial economics, and the calculations of time and uncertainty derived from it, are playing an increasingly important role in non-finance areas, such as monetary and environmental economics. In this 2001 book, Professors Le Roy and Werner supply a rigorous yet accessible graduate-level introduction to this subfield of microeconomic theory and general equilibrium theory. Since students often find the link between financial economics and equilibrium theory hard to grasp, they devote less attention to purely financial topics such as calculation of derivatives, (...) while aiming to make the connection explicit and clear in each stage of the exposition. Emphasis is placed on detailed study of two-date models, because almost all of the key ideas in financial economics can be developed in the two-date setting. In addition to rigorous analysis, substantial sections of discussion and examples are included to make the ideas readily understandable. (shrink)

L’espace parents dans la séparation ( eps ) de Mons (Belgique) est un dispositif d’accueil des parents en situation de séparation hautement conflictuelle. Le travail s’élabore autour de la réflexion commune avec les parents sur la qualité de la relation coparentale dans l’intérêt des enfants. Cet article vise à expliciter les processus et les outils utilisés dans le cadre de l’ eps. Après avoir développé les ancrages épistémologiques et le dispositif en lui-même, les auteurs proposent de montrer, au travers d’une (...) illustration clinique, les processus en place dans la construction de « l’équipe parentale ».

Il s'agit de la première édition de cette oeuvre majeure de Bodin. Jusqu'ici seul le texte latin était disponible (éd. L. Noak, 1857), ou la traduction anglaise de 1975, par Mrs. Kuntz. Le texte donné ici est celui d'une traduction française anonyme écrite très tôt après la mort de l'auteur (1596), dans une langue proche de celle de la République. Bodin fait ici converser sept sages, un juif, un musulman, un catholique romain, un luthérien, un calviniste, un adepte de la (...) religion naturelle et un "ethnique" (indien d'Amérique) à propos des mérites de leurs religions respectives. Loin de donner l'avantage au christianisme, il semble montrer une certaine inclinaison au judaïsme qui fera les délices des libertins du XVIIe siècle... (shrink)

There has often been criticism of the use which was made by certain sociologists toward the beginning of the century (Lévy-Bruhl in particular) of the adjective “primitive” to characterize the level of culture of peoples whom we formerly called “savage.” The term “archaic” perhaps creates fewer difficulties, but its etymology nevertheless involves the inconvenience of intimating that the societies in question might be closer to the origins than ours. Certain anthropologists, attempting to find an objective criterion which would permit us (...) to draw a line of demarcation between the so-called primitives and ourselves, use the term “peoples without writing” to designate the former—that is, they refer to a technique. It is true that there might be good grounds for specifying this criterion. Indeed, graphic representation can consist of rudimentary signs such as one sees on the messagesticks of the Australians or in the sketched stories, such as those with which the North American Indian covered animal skins. We can speak of writing from the moment that definite characters of precise conventional meaning appear; but from the pictogram to the abstract sign there are still many transitions. For example, in the pre-Columbian epoch, the writing system of the Aztecs “constituted a compromise between the ideogram, phonetism, and simple drawing.” Egyptian hieroglyphics were not yet totally freed from their pictographic origins. In the evolution which led to our modern system, the first step was taken when syllabic representation was adopted. But writing ceased to be reserved for specialists and truly became a widespread institution when the alphabet was invented; and that discovery, made no doubt toward the year 1800 b.c. by the Semitic peoples, came more than three thousand years after the first step. In general, the term “peoples without writing” does not in itself specify that it must be understood as meaning “peoples without an alphabet”; thus there is some doubt about civilizations like that of the Aztecs, endowed with a rather elaborate pictographic system. There would be good reason, moreover, to ask ourselves if the technique of writing really constitutes a reliable criterion for establishing a distinction between societies which stagnate in archaism and those which open up to history. Certain writers, such as Marcel Griaule or M. Gurvitch, would be inclined to refute it and to seek other technical criteria, such as the use of machines or reference to creative characteristics.

Mucoidy and cytotoxicity arise from two independent modifications of the phenotype of the bacterium Pseudomonas aeruginosa that contribute to the mortality and morbidity of cystic fibrosis. We show that, even though the transcriptional regulatory networks controlling both processes are quite different from a molecular or mechanistic point of view, they may be identical from a dynamic point of view: epigenesis may in both cases be the cause of the acquisition of these new phenotypes. This was highlighted by the identity of (...) formal graphs modelling these networks. A mathematical framework based on formal methods from computer science was defined and implemented with a software environment. It allows an easy and rigorous validation and certification of these models and of the experimental methods that can be proposed to falsify or validate the underlying hypothesis. (shrink)

No consensus yet exists on how to handle incidental fnd-ings in human subjects research. Yet empirical studies document IFs in a wide range of research studies, where IFs are fndings beyond the aims of the study that are of potential health or reproductive importance to the individual research participant. This paper reports recommendations of a two-year project group funded by NIH to study how to manage IFs in genetic and genomic research, as well as imaging research. We conclude that researchers (...) have an obligation to address the possibility of discovering IFs in their protocol and communications with the IRB, and in their consent forms and communications with research participants. Researchers should establish a pathway for handling IFs and communicate that to the IRB and research participants. We recommend a pathway and categorize IFs into those that must be disclosed to research participants, those that may be disclosed, and those that should not be disclosed. (shrink)
