Validation of a test battery for manufacturing machine operators

The present study determined if it was possible to develop a selection procedure which would effectively select machine operator applicants. A concurrent validity study was conducted on 140 employees with a job simulation as the criterion. The results indicated a correlation with the criterion of .71, and the Lawshe (1983) test of fairness revealed no significant bias for minority or female applicants. The utility analysis indicated a 16% increase in output would occur with the use of the validated selection system.     

EVOLUTION IN THERMODYNAMIC PERSPECTIVE: A HISTORICAL AND PHILOSOPHICAL ANGLE

Abstract. The recently suggested reformulation of Darwinian evolutionary theory, based on the thermodynamics of self-organizing processes, has strong philosophical implications. My claim is that the main philosophical merit of the thermodynamic approach, made especially clear in J.S. Wicken's work, is its insistence on the law-governed, continuous nature of evolution. I attempt to substantiate this claim following a historical analysis of beginning-of-the-century ideas on evolution and matter-life relationship, in particular, the fitness-of-the-environment-for-life theory of the Harvard physiologist L.J. Henderson. In addition, I point to an epistemological common ground underlying the studies of the “thermodynamics school” and other currently active research groups focusing on the emergence and evolution of biological organization.     

Decisions about life and death: Assessing the Law Reform Commission and the Presidential Commission Reports

This paper compares and critically comments upon certain aspects of the Canadian Law Reform Commission Report,Euthanasia, Aiding Suicide and Cessation of Treatment, and the United States Presidential Commission Report,Deciding to Forego Life-Sustaining Treatment. It focuses on their positions on euthanasia and on the general principles, values, and procedures that ought to govern practices of foregoing life-sustaining treatment. The paper first comments on the recent debate over the moral relevance of the killing/letting die distinction, since this issue appears crucial in assessing the rationality of the current, absolute prohibitions of direct killing in medical contexts, embodied both in law and in codes of ethics. This issue bears upon a question in the closing section—whether the withdrawal of foods and fluids is ever morally permissible.     

Mock Jurors' Evaluations of Child Sexual Abuse: The Impact of Memory Recovery and Therapeutic Intervention

The present research assessed whether mock jurors' decisions in a case involving allegations of child sexual abuse would be influenced by (1) the nature of the plaintiff's memory of the abuse (repressed, nonrepressed) and (2) therapeutic intervention (present, absent). Participants (N=123) were given a trial summary in which the plaintiff's memory and involvement in therapy were systematically varied to produce four conditions. Although verdicts varied only by sex of participant, some judgments of the plaintiff's claim were more favorable to the plaintiff in the non-repressed condition. Female participants were also less likely to believe that the claim involving memory repression was truthful when the woman was in therapy as opposed to not in therapy. Results also indicated that people who were aware of “False Memory Syndrome” were more likely to think the plaintiff was lying and less likely to think she was telling the truth compared to those who were not aware.

A longitudinal study of "intrusion-based reasoning" and posttraumatic stress disorder after exposure to a train disaster

Previously, we found that chronic PTSD relates to “intrusion-based reasoning” (IR), i.e. the tendency to interpret distressing intrusions themselves as evidence that danger is impending, regardless of objective danger information (Engelhard et al., Behav. Res. Ther. 39 (2001) 1139). This study was intended to elucidate the causal status of this relation. Twenty-nine residents of a Belgian town witnessed a train crash and were assessed for IR and PTSD symptoms within 1 month and were re-assessed for PTSD at 3.5 months. Fourteen control residents did not witness the crash and were also tested for IR. The IR paradigm involved rating the danger of brief scenarios in which objective danger and presence of intrusions about the crash were systematically varied. The directly exposed residents showed greater danger ratings to scenarios in which intrusions were included than did the controls. IR was strongly related to both acute and chronic PTSD symptoms. It did not significantly predict chronic PTSD symptoms after controlling for acute symptoms, although the partial correlation (r=0.26, p=0.09) was in the expected direction. The data suggest that IR is involved in the onset and maintenance of PTSD symptoms, but more clarity about causality awaits future larger and experimental studies.     

The nature of regularity and irregularity: evidence from Hebrew nominal inflection

Most evidence for the role of regular inflection as a default operation comes from languages that confound the morphological properties of regular and irregular forms with their phonological characteristics. For instance, regular plurals tend to faithfully preserve the base's phonology (e.g., rat-rats), whereas irregular nouns tend to alter it (e.g., mouse-mice). The distinction between regular and irregular inflection may thus be an epiphenomenon of phonological faithfulness. In Hebrew noun inflection, however, morphological regularity and phonological faithfulness can be distinguished: Nouns whose stems change in the plural may take either a regular or an irregular suffix, and nouns whose stems are preserved in the plural may take either a regular or an irregular suffix. We use this dissociation to examine two hallmarks of default inflection: its lack of dependence on analogies from similar regular nouns, and its application to nonroots such as names. We show that these hallmarks of regularity may be found whether or not the plural form preserves the stem faithfully: People apply the regular suffix to novel nouns that do not resemble existing nouns and to names that sound like irregular nouns, regardless of whether the stem is ordinarily preserved in the plural of that family of nouns. Moreover, when they pluralize names (e.g., the Barak-Barakim), they do not apply the stem changes that are found in their homophonous nouns (e.g., barak-brakim lightning), replicating an effect found in English and German. These findings show that the distinction between regular and irregular phenomena cannot be reduced to differences in the kinds of phonological changes associated with those phenomena in English. Instead, regularity and irregularity must be distinguished in terms of the kinds of mental computations that effect them: symbolic operations versus memorized idiosyncrasies. A corollary is that complex words are not generally dichotomizable as regular or irregular different aspects of a word may be regular or irregular depending on whether they violate the rule for that aspect and hence must be stored in memory.
