The present research investigates the relationships between demographic characteristics and employees' perceptions of appropriate pay-differentials (APD's). In order to investigate this relationship, we examined organizations in two different countries with different social philosophies. The dependent variable (APD's) is defined as what is felt and/or perceived by the individual to be the appropriate pay-differentials among positions with different responsibilities and at different organizational levels. Two different subject groups were used: 137 salaried employees from an automotive engineering company in the U.S.A., and 107 salaried employees from an engineering company in Sweden. Questionnaires constructed in English and Swedish included: (1) questions about individual demographics; (2) job factors; and (3) perception of appropriate pay-differentials using eight organizational charts. Results indicated that the influence of social philosophy, as expressed by organizational socialization processes, was limited in scope. Individual differences associated with employees' perceptions of appropriate pay-differentials should be taken into account when determining pay and compensation policies. These considerations may encourage employee participation in decision making and lead to better organizational outcomes.deceased. 相似文献

Although cerebral anoxia is not thought to be responsible for triggering near-death experiences (NDEs), the issue is not so clear in the case of hypercapnia. Detection of normal blood gases in Michael Sabom's (1982) case study seems to be the major reply to suggestions that hypercapnia may have a causal role in NDEs. We argue, however, that routine arterial measures of blood gases are not a reliable indicator of cerebral levels. 相似文献

In this article the perspective shifts to the “upstream” end of the agricultural knowledge and information system (AKIS).
Because knowledge policy and strategic decision-making are not the prerogative of the public sector, organizations such as
cooperative unions and multinational companies are included. After considering the influence of the changing environment on
the nature of the AKIS, the role of knowledge management and policy in the emerging knowledge and information market is examined.
Special attention is given to public and private R&D. The article then looks where information technology (IT) fits in and
what considerations determine strategic investment in IT projects and sustained services. Some of the European experiences
with this strategic investment are evaluated. 相似文献

This article offers an invitation to develop one's own unique clinical style, relying less on institutionalized schools of therapy and more on the therapist's own natural resources. An emphasis is placed upon understanding therapy as art, trusting one's imagination, and maintaining a healthy irreverence for professional politics. 相似文献

Despite demonstrations of the utility and cost effectiveness of behavioral programming, such techniques are not commonly employed in psychiatric inpatient settings. Several explanations for this have been proposed, including inadequate levels of training and competence in behavioral programming among prevalent treatment staff. This study employed a multiple choice inventory to assess behavioral knowledge among subjects representing several direct care disciplines commonly found in inpatient psychiatric settings. The results support assertions of relatively low levels of behavioral knowledge among disciplines that are most prevalent in such settings. The implications of these results for initiatives to enhance behavioral knowledge and skills are discussed. 相似文献
