Deliberate commission of category mistake. Crombie vs. Ryle

Crombie's acceptance of the deliberate commission of a category mistake in his defense of the meaningfulness of theological statements raises a pointed challenge to the philosophy of Ryle which seems not to have been specifically addressed in subsequent literature. We review the analysis which leads Crombie into it, including concepts of anomaly, deficiency, affinity, and inadequate notion, noting basic differences in method and attitude from Ryle. We express our own agreements and disagreements in keeping with an overall concern for the preservation of rationality in this sphere of language, finding acceptable distinct contributions to that end from both.     

A fuzzy system for mapping worker attributes to tasks

We developed a prototype of a rule-based expert system that facilitates a mapping from tasks comprising a job to the knowledge, skills, and abilities (KSAs) ostensibly required to perform the tasks. A variant of fuzzy logic was employed in the inference process. Signal detection theory was used to evaluate the performance of the system. The results indicated that the system performed well in terms of its ability to discriminate between the KSAs that are required of a task and those that are not. The discussion focuses on implications of the system and its use as an intelligent assistant in human resources planning.     

Communication Differences Between Physicians and Their Patients in an Oncology Setting

The physician-patient relationship has critical importance in the quality of medical care, especially in the oncology setting. Of particular interest over the past two decades has been the communication between physicians and their patients. It is understood that communication is related to patient and physician satisfaction as well as other medical outcomes. However, despite this interest and attention, investigators have only recently begun to assess the communication between physicians and patients from the patient's point of view. Additionally, previous investigations have primarily relied upon retrospective reports of the interaction from patients or physicians. The current investigation assessed physician–patient communication in an oncology setting, both as it was occurring and following the interaction. The units of analysis included participant ratings as well as those of trained observers. Findings revealed that physicians and patients disagree as to the valence of the messages which transpired. Additionally, results suggest that it is the patients who distort the messages in the positive direction. Research and clinical implications of this disagreement and positivity bias are discussed.     

Personality, Social Networks, and Perceived Social Support among Alcoholics: A Structural Equation Analysis

ABSTRACT In this study we tested relations among personality characteristics, social network properties, and perceived social support both concurrently and prospectively. A sample of 294 men in treatment at a Department of Veterans Affairs Alcohol Treatment Unit was assessed during treatment and 3 months after discharge. Results of the cross-sectional structural equation analyses indicated that the personality characteristics of extraversion and neu-roticism were related to both social network properties and perceived social support. Characteristics of the alcoholic's social network were also related to perceived availability of support. Longitudinal analyses of perceived social support after treatment indicated that two social network properties (size of the network and the proportion of confidants) were predictive net of initial levels of social support. Extraversion and neuroticism were found to be indi-rectly related to perceived social support at Time 2 through their effects on social network properties and perceived social support during treatment. Implications of these findings for models of the nature and determinants of perceived social support are discussed.
