This paper presents Manufacturing Resource Planning, an information system that will enable the developing and monitoring of strategic plans. Incorporation proven material and capacity requirements planning techniques, strategic planners can determine readily the impact of their plans on the manufacturing resources of the company. Decision making is more coordinated because all managers work from a common data base. However, the attainment of this level of planning sophistication is costly not only in capital outlays for computer software and hardware but also in the time to train users. But those firms who have successfully incorporated this integrated approach to strategic planning feel strongly that the end results justify the expenditures.  相似文献

We find strongly non-Ricardian results when we re-estimate Evans's [1988] model using a better approximation of the market value of wealth. We also examine the long-run properties of the data and find results consistent with our regression evidence when we allow for declining labor income as modeled by Gali (1990]. Our findings in support of non-Ricardian behavior by consumers stand in sharp contrast to those of both Evans and Gali.  相似文献

We provide improved evidence on effects that fund-raising, government support, and program revenue of U.S. higher education, hospital, and scientific research nonprofit organizations (NPOs) have on donations to those NPOs and provide improved estimates of price elasticities of donations to, and donor demand for output of, those NPOs. Applying econometric tests, we find the best-specified model is two-way fixed effects, which controls for organization-specific and time-specific factors. Results suggest that U.S. higher education, hospital, and scientific research NPOs fund-raise to the point where the marginal fund-raising dollar brings in zero dollars of donations, donor demand for output of hospitals and scientific research NPOs is price inelastic and price elastic, respectively, and results are not sensitive to specification of price.  相似文献

In this investigation, the moral development of physically abused (N = 28), neglected (N = 26), and nonmaltreated (N = 28) five‐year‐old children from low socioeconomic backgrounds was examined through observational measures of prosocial behaviors, moral transgressions, and emotions associated with moral development. Findings showed that physically abused children engaged in more stealing behaviors, whereas neglected children engaged in significantly more cheating behavior and less rule‐compatible behavior compared to nonmaltreated children. In addition, maltreatment status differences interacted with gender on several of the moral paradigms. Physically abused girls displayed significantly less guilt and fewer donation behaviors than neglected girls. The clinical implications for maltreated children's moral development are discussed, and targeted interventions are suggested.  相似文献

Childhood stealing is a distressing problem for families and may have wider community costs since childhood stealers often become adult criminals: This paper describes a therapeutic ‘map’ that emphasises direct engagement of the child, along with his/her family, in regrading the child from ‘stealer’ to ‘honest person’. Analysis of therapy with 45 children revealed a high level of family engagement and initial behaviour change. Furthermore, a follow-up telephone call made 6–12 months after completion of therapy sessions revealed that 81% of the children had not been stealing at all or had substantially reduced rates of stealing.  相似文献

This study examined how career certainty, grade level, and gender relate to short-term changes in work values (Human-Personal, Non-Work, Power-Control, Money-Security) among junior high and high school students (N = 496). With scores based on multivariate ANOVAs, the high and moderate career certainty groups scored significantly higher than the low certainty group on all work values except Non-Work at time 1 (similar results were found at time 2, 6 months later). Between time 1 and 2, each work value declined slightly but significantly; for both Human-Personal and Power-Control, however, the decline over time was greater for the high certainty group than for the low certainty group. The findings suggest that during adolescence, higher career certainty reflects greater engagement in a vocational identity search and a more active consideration of work values.  相似文献

In this paper, we examine whether county-level measures of poverty and social disadvantage are correlated with county-level variation in the black/white foster care placement gap. The black/white placement gap refers to the fact that when the rate of placement into foster care for black children is compared to the rate for white children living in the same area, the black placement rate is almost always higher than the rate for whites. Although differential exposure to poverty is often used to explain why the placement gap is so large, the problem has rarely been studied. Using Poisson event count models, we find that poverty, measured at the county ecological level, is associated with a narrower gap rather than a wider gap. The counterintuitive finding is due to the fact that the relationship between poverty and placement rates depends on race.  相似文献
