Although a number of valuable models of central‐local relationships in the nonprofit sector have been developed, particularly in relation to federal structures, there has been a tendency to assume that in any given organizational relationship central‐local structures will follow one common pattern. We argue that wider strategies are available: central dependency along one dimension may run with greater local autonomy along another. Such mixed tight‐loose structures may be of considerable importance in the “boundaryless” organizational environment of the future.  相似文献

Previous research on material requirements planning (MRP) systems has rarely considered the impact of the master production scheduling method used to promise customer orders and to allocate production capacity. Based on a simulation study of an MRP environment, we show that the correct selection of a master production schedule (MPS) method depends on the variance of end-item demand. In addition, we find evidence that the effectiveness of a particular MPS method can be enhanced by holding buffer inventory at the same level in the product structure as in the MPS.  相似文献

Fathers exist in the lives of women and children involved with child welfare authorities, and yet, they are rarely seen by child welfare. This invisibility exists whether or not fathers are deemed as risks or as assets to their families. Using an analysis of fundamental child welfare policies and practices and relevant literature, the paper examines how 'ghost' fathers are manufactured, and how this phenomenon affects families and professionals in child welfare. An analysis of gender, class, race and culture of child welfare discourses shows how these fathers are seen as deviant, dangerous, irresponsible and irrelevant, and even further, how absence in child welfare is inextricably linked to blaming mothers. In failing to work with fathers, child welfare ignores potential risks and assets for both mothers and children.  相似文献

In this paper the development of a new approach to group therapy is presented. Collaborative group therapy has been successfully used in working with people with schizophrenia. It has provided both participants and therapists with the opportunity to move away from a restrictive view of mental illness toward alternative self knowledge and empowerment. New ethnographic methodology has been used to measure both process and outcome of the group therapy.  相似文献

It is possible for a language to emerge with no direct linguistic history or outside linguistic influence. Al-Sayyid Bedouin Sign Language (ABSL) arose about 70 years ago in a small, insular community with a high incidence of profound prelingual neurosensory deafness. In ABSL, we have been able to identify the beginnings of phonology, morphology, syntax, and prosody. The linguistic elements we find in ABSL are not exclusively holistic, nor are they all compositional, but a combination of both. We do not, however, find in ABSL certain features that have been posited as essential even for a proto-language. ABSL has a highly regular syntax as well as word-internal compounding, also highly regular but quite distinct from syntax in its patterns. ABSL, however, has no discernable word-internal structure of the kind observed in more mature sign languages: no spatially organized morphology and no evident duality of phonological patterning.  相似文献

Select businesses in industry may attempt to compete through distinct strategies. But some may be successful in adopting distinct strategic profiles while others may not prove successful. In this study it was expected that six different groups of businesses might be present in the empirical exploration – those competing successfully with the low cost strategy and those competing unsuccessfully with this strategy; those competing successfully with the differentiation strategy and those competing unsuccessfully with this strategy; and those competing successfully with low cost and differentiation strategies and those competing unsuccessfully with these strategies. The results of the investigation portray the presence of three strategic profiles. They are unsuccessful low cost businesses with the lowest performance, unsuccessful differentiated businesses with the second lowest performance, and successful businesses with combination strategies with the highest performance.  相似文献

The sample survey, involving the use of specially developed questionnaires and instruments, is an important source of data regarding individual experiences and social-psychological characteristics for use in social indicator research. Variable errors of measurement are often given only cursory attention in presentations of survey sampling and social indicator theory and in the analysis of such data. These errors may, however, result in reduced precision of estimates and may affect statistical inferences drawn from the data. Some procedures for assessing the extent of variable measurement error are described and examples of their use in evaluating a survey instrument and data collected are discussed.  相似文献
