THE INFLUENCE OF TELECONFERENCING MEDIUM AND STATUS ON PARTICIPANTS' PERCEPTION OF THE AESTHETICISM,EVALUATION, PRIVACY,POTENCY, AND ACTIVITY OF THE MEDIUM1

This study investigated the influence of teleconferencing medium and status on users' reaction to the medium. Subjects received either high or medium status inductions, and subgroups solved a problem in two node audio, video, and face-to-face conferencing configurations. These subgroups proceeded through the three media treatment conditions in counterbalanced order, and responded to scales measuring the aestheticism, evaluation, privacy, potency, and activity of the medium. Analysis indicated both face-to-face and video conferencing elicited more positive aestheticism and evaluation reactions than the audio conferencing medium. Face-to-face and audio conferencing media were perceived as being more private than the video teleconferencing medium while both video and audio media were perceived as being more potent than face-to-face conferencing. The analysis revealed neither an activity of the medium nor status main effect. The results were discussed in light of information theory.     

RELATIONS BETWEEN WORK GROUP CHARACTERISTICS AND EFFECTIVENESS: IMPLICATIONS FOR DESIGNING EFFECTIVE WORK GROUPS

Five common themes were derived from the literature on effective work groups, and then characteristics representing the themes were related to effectivness criteria. Themes included job design, interdependence, composition, context, and process. They contained 19 group characteristics which were assessed by employees and managers. Effectiveness criteria included productivity, employee satisfaction, and manager judgments. Data were collected from 391 employees, 70 managers, and archival records for 80 work groups in a financial organization. Results showed that all three effectiveness criteria were predicted by the characteristics, and nearly all characteristics predicted some of the effectiveness criteria. The job design and process themes were slightly more predictive than the interdependence, composition, and context themes. Implications for designing effective work groups were discussed, and a 54-item measure of the 19 characteristics was presented for future research.     

Social identity and intergroup evaluative bias: Realistic categories and domain specific self-esteem in a conflict setting

Social identity theory predicts a link between self-esteem and intergroup discrimination. Previous research has failed to find consistent support for this prediction. Much of this research has, however, been beset by a number of methodological shortcomings. These shortcomings may have hindered attempts to discern a consistent relationship between self-esteem and intergroup discrimination. The current investigation sought to overcome these difficulties by utilizing, realistic groups, multidimensional measures of self-esteem and testing self-esteem before and after the manifestation of intergroup evaluative bias. The results demonstrate that when the members of realistic groups engage in evaluative intergroup bias, the esteem in which they hold specific self-images is enhanced. Of the 13 facets of self-esteem delineated by the instrument used in the present study significant increases were found in six particular domains: honesty, academic ability, verbal ability, physical appearance, religion and parental relations. Global self-esteem was unaffected by the display of bias. These findings emphasize the importance of using realistic groups and domain specific self-esteem when attempting to assess the role of self-esteem in intergroup discrimination.     

A FIELD STUDY OF PERFORMANCE APPRAISAL PURPOSE: RESEARCH- VERSUS ADMINISTRATIVE- BASED RATINGS

Many researchers have discussed the theoretical and practical importance of rating purpose. Nevertheless, the body of empirical studies, the majority of which were conducted in a laboratory setting, focus on leniency. There has been little research on other effects of rating purpose. The present study examines 223 ratees in a field setting for whom there were both administrative-based performance appraisal ratings (which were actually used for personnel decisions) and research-based performance appraisal ratings (obtained for a validation study). Two of the hypotheses were supported; administrative ratings were more lenient than research-based ratings. The administrative-based ratings demonstrated a statistically significant relationship with ratee seniority, while the research-based ratings did not. There was mixed support for a third hypothesis: Research ratings were significantly correlated with a predictor, while the administrative ratings were not. The difference between the validity coefficients, however, was not significant. Contrary to the hypothesis, the rank order between administrative-based and research-based ratings was relatively high ( r = 33).     

In Defence of Direct Realism

In her careful consideration of my book, The Problem of Perception (henceforth, PP), Susanna Siegel highlights what she takes to be a number of shortcomings in the work. First, she suggests that a sense-datum theorist has two options–what she calls the "complex sense-data option" and the "two-factor option"–that survive the argument of my book unscathed. I consider these two options in the first two sections of this reply. Secondly, she criticizes my suggestion that there are three and only three basic and independent sources of perceptual consciousness: an issue I take up in my third section. Thirdly, she expresses reservations about my response to the argument from hallucination. In particular, she argues that the phenomenological considerations on which I put so much weight cannot settle the fundamental issue here. I address this criticism in the fourth section of this reply. Finally, she spends a certain amount of time discussing the notion of a "veridicality-rele-vant property", a topic to which I devote the concluding section of this reply.
