Psychiatric nurses were included in family therapy training, but few of them applied their new skills in their work settings. A seeming paradox was the lack of support given these trainees by the nursing administration. The situation became understandable when analyzed as a "family" problem; the nurses being members of the larger social system comprising the psychiatry department. Strategies were accordingly adopted to modify aspects of the system, and this facilitated more positive contributions by nurses as family therapists.  相似文献

How relevant are traditional innovation ideas for project-based firms? This paper asks if project-based firms provide a context supportive of innovation or indeed if they view it as useful. Based on research in firms from a variety of sectors, including telecommunications, information systems, computers, financial services and engineering, procurement and construction, the paper reveals that the very project control systems around which the firms operate serve to stifle innovation. Project-based firms—regardless of sector—prioritise efficient management of projects, tolerating the use of slack resources only when absolutely necessary. Finally innovation is not seen as universally useful, but primarily as costly and dangerous. It concludes that the space at which ‘innovation’ and ‘projects’ comes together is still dominated by ideas on how to correctly manage projects, rather than how to effectively manage innovation. Innovation of ideas on managing innovation projects may be merited.  相似文献

Performance Assessment (PA) is the use of mathematical models to simulate the long-term behavior of engineered and geologic barriers in a nuclear waste repository; methods of uncertainty analysis are used to assess effects of parametric and conceptual uncertainties associated with the model system upon the uncertainty in outcomes of the simulation. PA is required by the U.S. Environmental Protection Agency as part of its certification process for geologic repositories for nuclear waste. This paper is a dialogue to explore the value and limitations of PA. Two skeptics acknowledge the utility of PA in organizing the scientific investigations that are necessary for confident siting and licensing of a repository; however, they maintain that the PA process, at least as it is currently implemented, is an essentially unscientific process with shortcomings that may provide results of limited use in evaluating actual effects on public health and safety. Conceptual uncertainties in a PA analysis can be so great that results can be confidently applied only over short time ranges, the antithesis of the purpose behind long-term, geologic disposal. Two proponents of PA agree that performance assessment is unscientific, but only in the sense that PA is an engineering analysis that uses existing scientific knowledge to support public policy decisions, rather than an investigation intended to increase fundamental knowledge of nature; PA has different goals and constraints than a typical scientific study. The proponents describe an ideal, six-step process for conducting generalized PA, here called probabilistic systems analysis (PSA); they note that virtually all scientific content of a PA is introduced during the model-building steps of a PSA; they contend that a PA based on simple but scientifically acceptable mathematical models can provide useful and objective input to regulatory decision makers. The value of the results of any PA must lie between these two views and will depend on the level of knowledge of the site, the degree to which models capture actual physical and chemical processes, the time over which extrapolations are made, and the proper evaluation of health risks attending implementation of the repository. The challenge is in evaluating whether the quality of the PA matches the needs of decision makers charged with protecting the health and safety of the public.  相似文献

The paper emphasizes three interrelated questions about the decline in relative farm to non-farm prices in the United States since 1973: (1) Is it unusual, (2) What caused it, and (3) Is it likely to continue? We find that based on historical and international evidence this phenomenon may be considered unusual. Separating farm price and income support in 1973 and growing relative productivity in agriculture have been the major contributors to changing the trend of the relative farm goods inflation. This trend is likely to continue based on predicted steady growth of relative agricultural productivity and continuation of direct payments and other forms of farm income support policies.  相似文献

This paper considers the use of a local linear kernel regression method to test whether the mean function of a sequence of long-range dependent processes has discontinuities or change-points. It proposes a non-parametric estimation procedure and then establishes an asymptotic theory for the estimation procedure. Examples, simulated and real, illustrate the estimation procedure.  相似文献

For multiracial adolescents, forming a sense of self and identity can be complicated, even at the level of classifying themselves in terms of racial group membership. Using a Race Self Complexity ( Winston et al., 2004 ) theoretical framework, this study used an open‐ended question to examine the racial self‐identification fluidity of 66 adolescents during the 7th, 8th, and 11th grades. This sample included 22 Black/White 1 multiracial adolescents, as well as a matched sample of 22 Black and 22 White adolescents. Seventy‐three percent of the multiracial adolescents changed their racial self‐identification in the form of two time change patterns with a number of consolidating and differentiating racial self‐identification variations. There was no change for the monoracial adolescents. These results suggest that within the lives of multiracial adolescents, the process of racial self‐identification may be a personality characteristic adaptation to the meaning of race in American society that may change across time, place, and role.  相似文献

Black Greek‐letter fraternities (herein after “BGLFs”) are unique and complex organizations with a rich history. Holding the ideals of high academic achievement, developing and sustaining fictive‐kinship ties, maintaining strong racial and gender identity, implementing a racial uplift agenda, and demonstrating a commitment to the perpetuity of their organizations together define BGLF members. Drawing upon the growing corpus of Black fraternity scholarship, this article first investigates the extent to which Black fraternities have remained faithful to these founding ideals. Second, it explores the ways in which Black fraternities articulate fidelity to these founding precepts. Third, it assesses the degree to which Black fraternities are currently consistent with these foundational ideals. And fourth, it examines the future of Black, collegiate‐based fraternalism in specific to contemporary challenges to BGLF's function and even existence, especially in regard to hazing. Broader implications, specifically in the legal realm, are discussed.  相似文献

The Supported Accommodation Assistance Program (SAAP) provides services for homeless people. After demonstrating that the Program is intended to assist people to move on to independent living, the following paper examines the implications of remaining in SAAP services for longer than would otherwise be necessary because there is no where else to go. In particular, the broader social functions of SAAP are examined in the light of the work of Michel Foucault. It is suggested that SAAP serves a specific social function in exerting socially approved power over SAAP users who are forced to remain in SAAP services for longer than would otherwise be required if affordable and appropriate accommodation were available.  相似文献
