This research investigated the relationships between technology, interdependence, job characteristics, and employee satisfaction, performance, and influence. Technology was operationalized at the individual level of analysis to include the dimensions of input uncertainty, conversion uncertainty, and output uncertainty. Pooled, sequential, and reciprocal interdependence was assessed. The results indicated that input and conversion uncertainty and interdependence were strongly related to such job characteristics as autonomy, skill variety, task identity, task significance, and task feedback. While the job characteristics related positively to employee satisfaction, input and conversion uncertainty related negatively to satisfaction, thus creating a mutual suppression effect. Although the uncertainty dimensions did not relate significantly to performance, there is some evidence that this negative relationship was being suppressed by the positive relationship between job characteristics and performance. Both the job characteristics and the technology dimensions related positively to influence. Results were discussed in terms of appropriate matches between technology and job characteristics. 相似文献

This paper presents 10 general observations about current software for instruction in psychology and examines selected examples employing four instructional techniques for computer-assisted instruction. We find that although the number of programs employing experimental or data-oriented approaches to psychology as a primary vehicle of instruction is increasing, tutorial drill and practice programs and gaming are not well represented. 相似文献

A method of constructing digital filters is outlined and illustrated in an application for research uses of EEG feedback. The method is based on least squares estimation with geometric weighting. Old data in the time series are discounted according to age, as new data arrive. Recurrence relations are used, allowing the computations to be performed in real time. A FORTRAN digital filter is formulated that simultaneously estimates (1) the spectral power in a band centered at a target frequency, (2) the total spectral power, and (3) the dominant frequency. 相似文献

The synchronous paradigm is a model of families whose members remain uninvolved and disconnected from each other yet somehow maintain relatively unvarying or even rigid patterns of behavior. In the synchronous paradigm, calm agreement and harmonious unity of action are valued above all. The concept of synchronous operation was first formulated by Constantine to solve certain theoretical problems growing out of the work of Kantor and Lehr. The theory has been elaborated upon through linkages established with other clinical and theoretical models of family dysfunction. Clinical experience in treating synchronous families has now contributed more detailed and practical understanding. Clinically, disabled synchronous families may present as bland, boring, or even death-like. They may have considerable difficulty accommodating to necessary developmental changes or to the demands of life crises, employing a variety of strategies to maintain the appearance of synchrony at the expense of adaptation. Their ability to ignore change and to absorb interventions can tax the abilities of even the most creative and energetic therapist. On the other hand, the quiet efficiency of the family and the social sensitivity of its members can be strong assets. Awareness of their strengths and special vulnerabilities can help the family therapist work more effectively with synchronous families. 相似文献

Personal space zones were examined amongst Arab and American university students by jointly varying degree of acquaintanceship and sex of subject. Overall, there were few differences between Arab and American males. Arab females, however, showed dramatic differences in comparison to American males and females and to Arab males. Arab females kept male friends very far away relative to female friends. Indeed, male friends were kept almost as far away as male strangers. 相似文献

The effects of stimulus person characteristics (viz., race, occupational status, religion, and nationality) and the respondent's level of dogmatism upon the social distance responses of a sample of Canadian university students were examined. Occupational status, race, and nationality of the stimulus person emerged as significant determinants, with occupational status being by far the most important. Dogmatism was also correlated with social distance responses. Highly dogmatic persons, but not those low in dogmatism, focused on occupational status in deciding acceptable bounds of intimacy with others. Several explanations for the prominence of occupational status as a social distance cue are discussed. As well, directions for future research into social distance norms in Canada are suggested. 相似文献
