The Effects of Decision Outcome Dispersion Upon Organizational Decision Making

The effects of varying decision outcome dispersion on organizational decision making were investigated under individual and group decision making conditions. Thirty-six female and pg]36 male subjects made decisions for organizational decision scenarios in which outcomes affected primarily the decision maker, people other than the decision maker, or a group of which the decision maker was a member. Subjects rated their levels of perceived risk and confidence in their decisions and made decisions within a simulated context of either a small or a large organization. Results indicated that subjects perceived significantly less risk and more confidence in their decisions when outcomes affected primarily themselves rather than others regardless of whether the decisions were made individually or by a group. Males perceived their decisions as significantly more risky than females. Induced organizational size did not significantly influence decision making.

     

The Personal and Social Worries of Adolescents in Northern Ireland: Results of a Survey

The aim of this study was to ascertain the self-perceived social and personal concerns of adolescents attending educational institutions in Northern Ireland. 446 questionnaires from 15-18-year-old students at ten institutions were analysed in order to determine the frequency with which respondents reported worrying about the following broad areas: school, choosing a job, finding a job, home, starting work, opposite-sex relationships, personal issues, and relating to others. The effects of variables such as gender, age and nature of educational institution attended were also examined. The results indicated that most frequent worry was reported about finding and choosing employment, personal issues and opposite-sex relationships. Gender, age and religious affiliation of school attended exerted major effects. Implications for those involved in working with adolescents within educational contexts are discussed.     

Relevance reviewed: The case of argumentum ad hominem

This article aims tt providing some conceptual tools for dealing adequately with relevance in argumentative discourse. For this purpose, argumentative relevance is defined as a functional interactional relation between certain elements in the discourse. In addition to the distinction between interpretive and evaluative relevance that can be traced in the literature, analytic relevance is introduced as an intermediary concept. In order to classify the various problems of relevance arising in interpreting, analyzing and evaluating argumentative discourse, a taxonomy is proposed in which the concept of relevance is differentiated along three co-ordinate dimensions: object, domain and aspect. With the help of this taxonomy, it can be shown that the problems of evaluative relevance with which the standard approach to fallacies cannot satisfactory deal can be more systematically approached within a pragma-dialectical framework. This is demonstrated for the argumentum and hominem, which is erroneously treated as a homogenous type of relevance fallacy in logico-centric analyses, so that cases where this is not justified must be treated as ad hoc exceptions.     

Chimpanzee (Pan troglodytes) spatial problem solving with the use of mirrors and televised equivalents of mirrors

Two adult male chimpanzees reached through a hole in the wall of their home cage and, by tracking the images of their hands and of an otherwise hidden target object in a mirror or closed-circuit television picture, moved their hands in whichever direction was necessary to make contact with the target object. They discriminated between live video images and tapes and performed effectively when the target objects were presented in novel locations and when the video picture was presented at random in different orientations. There was thus no consistent relation between the location of images on the monitor and the location of their real-world counterparts. Comparable performances in monkeys and nonprimates seem unlikely.     

Fallacies in pragma-dialectical perspective

In the pragma-dialectical approach, fallacies are considered incorrect moves in a discussion for which the goal is successful resolution of a dispute. Ten rules are given for effective conduct at the various stages of such a critical discussion (confrontation, opening, argumentation, concluding). Fallacies are discussed as violations of these rules, taking into account all speech acts which are traditionally recognized as fallacies. Special attention is paid to the role played by implicitness in fallacies in everyday language use. It is stressed that identifying and acknowledging fallacies in ordinary discussions always has a conditional character. Differences between the pragma-dialectical perspective, the Standard Treatment, and the formal logic approach to fallacy analysis are discussed.     

The listening heart and the chi square: clinical and empirical perceptions in the family therapy of anorexia nervosa

Clinical and empirical methods are commonly considered to be complementary activities. However, many people in the fields of mental health and social welfare espouse a strong adherence to experimental, scientific methods for the evolution of theory and practice and consider only that which has been experimentally tested as‘really true”. Others would propose the clinical method as the main source of useful knowledge and are suspicious of enumeration and quantification as sources of useful information. Formal, empirical methodology is well and extensively described whilst there is less systematic exposition of the clinical method. Family therapy evolved in a context in which activity was visible and the emerging discipline was propelled by a theoretical framework with strongly scientific origins that was critical of the exclusive clinical method of pre-existing psychotherapies. This paper describes some of the clinically based contributions to the family therapy of anorexia nervosa and compares this information with that which comes out of the Maudsley trials of psychotherapies in anorexia nervosa.     

Direct comparisons between residential and community students on school performance measures in a public school setting

The purpose of the current study was to evaluate the school performance of residential youth who attended a public school setting. Direct comparisons were made between the residential youth and students in the community on a number of school measures. Results from a multivariate analysis of covariance indicated that the residential students had significantly lower grades, participated in significantly fewer extracurricular activities, and exhibited more problematic behaviors such as tardies and absences. These findings were consistent with previous research which found that many residential youth have a number of behavioral, social, and academic difficulties that interfere with school functioning. A number of recommendations were made regarding educational placement for residential youth.     

Brain dynamics,psychophysiological uncertainty and behavioral learning

The present paper takes a first step toward the integration of recent findings on brain dynamics and learning into established fields of psychophysiological science. Leading-edge studies of brain dynamics have shown that the brain manifests an inherent variability and that, when new stimuli (i.e., “problems”) are presented to the organism, brain chaos increases.
