Erotetic implications

Three semantic relations are analyzed: the relation of implication of a question by a question and a set of declarative sentences, the relation of implication of a question by a question, and the relation of strong implication of a question by a question and a set of declarative sentences. The connections between these concepts and the concepts of relative soundness, partial answerhood and presupposition are examined. The principal results are theorems about, to speak generally, epistemic reducibility of well-posed questions to sequences of implied yes-no questions.     

Erotetic arguments: A preliminary analysis

The concept of erotetic argument is introduced. Two relations between sets of declarative sentences and questions are analysed; and two classes of erotetic arguments are characterized.     

Erotetic Logic And Explanation By Abnormic Hypotheses

A relativized concept of a possiblecorrect answer to a why-question is introduced. Acertain procedure of looking for acceptable answers towhy-questions is analyzed in terms of erotetic logic,i.e., the logic of questions.     

Deduction and Reduction Theorems for Inferential Erotetic Logic

The concepts of question evocation and erotetic implication play central role in Inferential Erotetic Logic. In this paper, deduction theorems for question evocation and erotetic implication are proven. Moreover, it is shown how question evocation by a finite non-empty set of declaratives can be reduced to question evocation by the empty set, and how erotetic implication based on a finite non-empty set of declaratives can be reduced to a relation between questions only.     

A Cut-Free Sequent Calculus for Defeasible Erotetic Inferences

In recent years, the effort to formalize erotetic inferences—i.e., inferences to and from questions—has become a central concern for those working in erotetic logic. However, few have sought to formulate a proof theory for these inferences. To fill this lacuna, we construct a calculus for (classes of) sequents that are sound and complete for two species of erotetic inferences studied by Inferential Erotetic Logic (IEL): erotetic evocation and erotetic implication. While an effort has been made to axiomatize the former in a sequent system, there is currently no proof theory for the latter. Moreover, the extant axiomatization of erotetic evocation fails to capture its defeasible character and provides no rules for introducing or eliminating question-forming operators. In contrast, our calculus encodes defeasibility conditions on sequents and provides rules governing the introduction and elimination of erotetic formulas. We demonstrate that an elimination theorem holds for a version of the cut rule that applies to both declarative and erotetic formulas and that the rules for the axiomatic account of question evocation in IEL are admissible in our system.

     

Work, Competences and Learning Scenarios for the Future

Il arrive que les occasions d'apprentissage et d'acquisition des compétences et des aptitudes soient tiées aux opportunités professionnelles et ainsi, indirectement, au développement de l'économie. L auteur illustre, avec cinq scénarios, comment l'apprentissage peut être conditionné par des choix macro-économiques et macro-sociaux.
Opportunities for learning and the acquisition of competences or skills happen to be linked to work opportunities and thence indirectly to the development of the economy. The author sketches five scenarios indicating how learning may be conditioned by macroeconomic and macro-social choices.     

Validity and Application of Computer-simulated Scenarios in Personnel Assessment

In Germany computer-simulated scenarios have been applied in personnel management for several years. Their goals are either to assess how potential managers cope with complex and connected problem states (job aptitude testing aspect) or to provide feedback on manager strengths and weaknesses in dealing with complexity, and how to modify these when necessary (training aspect). This paper presents and evaluates those scenarios that have been subjected to validity studies.     

Search for Security

This article uses fictionalized accounts of counseling situations in various periods of history—prehistorical, Greek, Middle Ages, and the twentieth century—to illustrate that man's search for security, his need for an answer to the question “What shall I do?” and other men's responses to that need have not changed much throughout history.     

Emergence,Story, and the Challenge of Positive Scenarios

This article is divided into three parts. The first part describes the paradox of positive scenarios: they are much harder to write than negative scenarios. The second part describes the logic of emergent systems whose properties are neither reducible to nor predictable from the properties of their component parts. The third part shows how the concept of emergence can be used to lend plausibility to those optimistic scenarios that might otherwise be rejected as mere wishful thinking.     

Development of Role-Play Scenarios for Teaching Responsible Conduct of Research

We describe the development, testing, and formative evaluation of nine role-play scenarios for teaching central topics in the responsible conduct of research to graduate students in science and engineering. In response to formative evaluation surveys, students reported that the role-plays were more engaging and promoted deeper understanding than a lecture or case study covering the same topic. In the future, summative evaluations will test whether students display this deeper understanding and retain the lessons of the role-play experience.     

In Search of Sociality

Abstract

This paper reviews some of the growing body of work in the analytic philosophy of social phenomena, with special reference to the question whether adequate accounts of particular social phenomena can be given in terms that are individualistic in a sense that is specified. The discussion focusses on accounts of what have come to be known as shared intention and action. There is also some consideration of accounts of social convention and collective belief. Particular attention is paid to the need to explain the association of certain rights and obligations with the phenomena at issue.

In Search of Home

ABSTRACT This is a philosophical treatment of the phenomenon of home. A distinction is drawn between home and permanent residence and birthplace. Through discussion of the philosophy of Vaclav Havel, home is discovered to be a multi-level structure that may contain several homes on different and identical levels. Exclusionist concepts of home such as nationalism and fundamentalist monotheism deny this. Home is conditions that allow personal self fulfilment. Our actual home is the result of our efforts to reach our ideal home, departing from our natural home. Hospitality, personal and collective, is extension of conditions of home to a guest who may be homeless or in exile. The current use of 'home' by inhospitable, excluding, territorial monopolies such as the European Community, the US immigration service, and Hong Kong officials, as in 'returning refugees back home', is an Orwellian misuse of the linguistically assumed, positive relations between person and home to legitimise morally abhorrent policies.
