conclusion The Information Age has revolutionized the workplace. While it is possible to purchase or copy machines and technology, their very interchangeability means they fail to cre-ate a sustained competitive advantage for an organization (Barney, 1991). The research directions this paper offers are intended to develop firm knowledge that allows creation of inimitable human resources. Importantly, in the rush to embrace new information technologies, organizations must remember the fundamental principle that workers will invest in firm goals in the presence of shared values and a commitment by the firm to make their well-being a priority. We urge continued attention to fulfillment of the psy-chological contract, and to the "people issues" that frequently seem less critical than issues of hardware or technology.  相似文献

This study examines the effectiveness of social support networks on psychological well-being among 602 homeless and runaway adolescents. The respondents were interviewed in shelters, drop-in centers, and on the streets in cities of four Midwestern states (Missouri, Iowa, Nebraska, and Kansas). The path model was used to test the direct effect of family abuse and precocious independence on adolescent depressive symptoms and indirect effects through social support networks. Results indicate that although abusive family origins contribute directly to depressive symptoms there are indirect effects of family abuse and early independence through social support networks. Family abuse and early independence drive homeless adolescents to rely on peers for social support. While support from friends on the street reduces depression, association with deviant peers increases depression.  相似文献

A multiple objective linear programming (MOLP) method utilizing interval criterion weights is applied to the problem of media selection. Using this technique, it is possible to analyze a problem more explicitly in terms of the several objectives inherent in many media selection situations. In order to illustrate the interval criterion weights approach, a multiple objective hierarchical media selection model is presented and its computer results discussed. In addition to being able to deal more directly with different decision criteria, a distinguishing feature of the mathematical analysis applied here is that its output enables the media-planner to be presented with a small cluster of candidate media schedules (rather than just one). Then, from this list, the media-planner should be in a position to qualitatively make a final choice as a close approximation to his optimal solution.  相似文献

Expectancy theory has been criticized for its omission of normative, habitual, and other motivational elements. This paper describes the sources and features of an integrative motivational model from the field of preventive health care that combines expectancy/valence factors with habitual, normative, and conative motivational elements. The model is viewed as having implications for work motivation as well.  相似文献

Abstract As fertility comes increasingly under voluntary control in a developing society, it can be argued that individual desires or preferences about children will become more salient and more significant for eventual fertility. Hence, the study of preferences is increasingly important as contraceptive use is extended and results in decreasing the number of unwanted births.(1) Further changes in fertility then depend on changes in preferences. The assumption is that people will at least try to achieve the families they want, if the means to do so are available. The fact that contraception is used at all is some evidence of the soundness of this assumption, although it should be recognized that family size desires operate in a complex of preferences, under varying degrees of conflict and control. To expect a one-to-one relationship between attitudes or preferences and overt behaviour would be simplistic.  相似文献

This article reports on the impact of the Savvy Caregiver Program (SCP) on English-speaking caregivers of Hispanic, Black/African American, and Asian/Pacific Islander descent. Caregivers completed a questionnaire prior to study enrollment, at 6 and 12 months postenrollment. Caregivers in all 3 ethnic groups showed more caregiver competence, reduced depression, greater tolerance for care recipients’ memory problems, better management of their overall situation, and improved perception of that situation 6 months and 12 months post-enrollment. The study demonstrates that in the sample studied the SCP was as effective in helping ethnically diverse caregivers as it has shown to be with Caucasian caregivers.  相似文献
