This paper reviews the planning practices in multinational firms, focusing particularly on the relationship between subsidiaries and head offices during the planning process. It examines the planning problems experienced by multinationals using a simple paradigm to classify problems according to whether their origin was primarily with home office or with subsidiary; with the planning system itself or with the managers involved in running that system. 相似文献

The problem of keeping abreast of relevant competitive developments for strategic purposes is common to many organizations. In this article the authors describe a system which they have developed and which is currently in operation which they believe can prove beneficial in meeting this need. They believe that their system provides competitive data in a useful form. Also it ensures that information, and not data, are processed and provided for planners and managers to support their decision-making. 相似文献

It has been demonstrated that sexual minority men (SMM) participate in sexting. While research has shown that engagement in the exchange of sexually explicit media is associated with poor health outcomes, no previous research has investigated its association with sleep health outcomes. This study sought to examine the association between sexually explicit media and sleep health among SMM, a population that suffers from poor sleep health. A popular geosocial networking application was used to recruit SMM individuals (N?=?580) in the Paris, France, metropolitan area. Multivariate analyses, adjusting for sociodemographics, were used to test the association between the frequency of sexually explicit messaging and three dimensions of sleep health: (1) sleep quality, (2) sleep duration, and (3) two aspects of sleep problems. In multivariate analyses, those who reported engaging in sexually explicit messaging more were more likely to report getting less than seven?hours of sleep (aRR = 1.24; 95% CI = 1.08, 1.43) compared with those who reported engaging in sexually explicit messaging less. No significant associations were found between sexting and sleep quality or reporting sleep problems. Sexually explicit messaging was associated with shorter sleep duration. Intervention targeted at individuals who sext could potentially improve sleep health outcomes. 相似文献

The current study combined a management technique termed “Service Review” with performance scorecards to enhance staff and consumer behavior in a human service setting consisting of 11 supervisors and 56 front-line staff working with 9 adult consumers with challenging behaviors. Results of our intervention showed that service review and scorecards produced significant staff behavior changes that were maintained over time. Positive consumer outcomes were also correlated with staff performance changes. The behavioral package of training, clinical consultation, service review, biweekly manager meetings, scorecards, and public posting has the potential to reduce the need for monetary staff incentives. 相似文献

Environmental variables have an important effect on the reliability of many products such as coatings and polymeric composites. Long-term prediction of the performance or service life of such products must take into account the probabilistic/stochastic nature of the outdoor weather. In this article, we propose a time series modeling procedure to model the time series data of daily accumulated degradation. Daily accumulated degradation is the total amount of degradation accrued within one day and can be obtained by using a degradation rate model for the product and the weather data. The fitted model of the time series can then be used to estimate the future distribution of cumulative degradation over a period of time, and to compute reliability measures such as the probability of failure. The modeling technique and estimation method are illustrated using the degradation of a solar reflector material. We also provide a method to construct approximate confidence intervals for the probability of failure. 相似文献

Abstract Participation in rural development programs that organize members into local cooperative groups can alter the decision-making environment facing couples to reflect some of the negative consequences of childbearing. This study uses data from Nepal, collected through a combination of ethnographic and survey methods, to test the effects of participation in such a development program on fertility behavior. Results demonstrate that program participants are much more likely to use contraceptives to limit their fertility than are non-participants. The study provides empirical support for theories linking this type of institutional change to fertility and indicates a policy option that can allow some negative consequences of childbearing to affect couples' fertility decisions. 相似文献

This paper examines the relationship between environmental regulatory influence and product innovation in a multi-industry sample of manufacturing organizations. Our theory argues that the influence of environmental regulation on the level of product innovation in a manufacturing organization is at least partially contingent on the organization's internal characteristics—in particular, its structural flexibility and production process flexibility. Hypotheses are derived from our theory and tested, and the results are consistent with the conclusion that structural flexibility and production process flexibility moderate the environmental regulatory influence–product innovation relationship. Whether environmental regulation inhibits or promotes product innovation seems to depend at least in part on certain internal features of an organization. We discuss implications of our results for future organization studies research on environmental regulation, and for research on other types of external constraints on organizational performance. 相似文献

ABSTRACT This article works to dispel the myth that Puerto Rican female urban high school students living in poverty are not capable of performing at high academic levels. This article attempts to counteract these beliefs by describing the four success factors that seven Puerto Rican female high school students attribute to their high academic achievement. These success factors are: (1) religiosity and extracurricular activities as sources of social capital, (2) affirming and maintaining a Puerto Rican identity, (3) maternal influences on students' academic achievement and, (4) the potential for caring teachers and other school staff to influence high academic achievement. Finally, our findings suggest that opportunities for Latinas and other youth of color are still inequitably structured in large, comprehensive high schools. Hence, we argue that schools must continue to bridge the large gap between themselves and the families/communities they serve and utilize the funds of knowledge and social capital that their students already bring to school. 相似文献
