This study explores forces that push public agencies to overcome barriers to cooperation. Case studies of nine groups of local school districts examined the pressures that shaped local participation in cooperative programs. The literature on relationships among organizations suggests six possible reasons to bear the costs of cooperation: to get more resources, to satisfy norms and values, to obtain political advantage, to solve problems, to reduce uncertainty, and to obey legal mandates. Data from the cases illustrate strengths and weaknesses of these six theoretical lines of argument as they apply to the decisions of public managers coping with complex realities. A process model of cooperation integrates the lessons of the data into a perspective that highlights the role of demands for improved performance. The model offers realistic guidance for the design of workable cooperative relationships. 相似文献

Major reforms to cash assistance and other welfare programsin the 1990s raise questions about whether states gained newflexibility in setting social policies, and, if so, how theyexercised this flexibility. We extend prior research on statesocial policy by examining trends during the middle to late1990s in five areas of cash or near-cash policy affecting theeconomic security of low-income families. We find evidence ofsubstantial change in the generosity and the availability ofthese benefits between 1994 and 1999, along with evidence ofgreater divergence or cross-state variation in policy choices.By considering several forms of assistance simultaneously, wealso find evidence that states constricted traditional welfare-basedassistance while expanding some forms of non-welfare supportfor the working poor. 相似文献

Preliminary findings on the outcomes of family-focused counseling interventions for alienated and estranged children are presented based upon data from a longitudinal study of children in chronic custody disputes who were interviewed as young adults and from the clinical records of long-term therapy with these children who were resisting visitation. 相似文献

In this article, controversies and problems with parental alienation syndrome are discussed. A reformulation focusing on the alienated child is proposed, and these children are clearly distinguished from other children who resist or refuse contact with a parent following separation or divorce for a variety of normal, expectable reasons, including estrangement. A systemic array of contributing factors are described that can create and/or consolidate alienation in children, including intense marital conflict, a humiliating separation, parental personalities and behaviors, protracted litigation, and professional mismanagement. These factors are understood in the context of the child's capacities and vulnerabilities. 相似文献

This article describes goals and strategies for family-focused counseling and therapy when children are alienated from a parent after separation and divorce. The confidential intervention takes place within a legally defined contract and is based on a careful assessment of the dynamics of the multiple factors that contribute to the alienation and how the chilďs development is affected. Strategies for forming multiple therapeutic alliances with often reluctant, recalcitrant, and polarized parents are discussed together with ways of helping the child directly. 相似文献

Latent Fingermark Aging Patterns (Part III): Discontinuity Index as One Indicator of Degradation 下载免费PDF全文
Josep De Alcaraz‐Fossoul Ph.D. Carme Barrot Feixat Ph.D. Clara Carreras‐Marin M.Sc. Jack Tasker B.Sc. Sara C. Zapico Ph.D. Manel Gené Badia Ph.D. 《Journal of forensic sciences》2017,62(5):1180-1187
This article is the third in a series of reports exploring quantifiable visual parameters of the aging process of latent fingermarks. On this occasion, research is focused on the occurrence of ridge discontinuities (i.e. breakages) as a function of time. Experiment variables included type of secretion (eccrine and sebaceous), substrate (glass and plastic), and exposure to natural light (dark, shade, and direct light) over a 6 months period. Fingermarks were sequentially visualized with titanium dioxide powder, photographed, and the number of naturally occurring ridge discontinuities subsequently evaluated. A semi‐quantitative value, named Discontinuity Index, was used to better characterize this aging parameter. Results indicated that ridges of sebaceous depositions on glass were generally less affected by the environmental conditions compared with those on plastic surface. In addition, aging in darkness was not always the best condition for preservation, and the direct exposure to light seemed not to affect the degradation under certain conditions. 相似文献

Abstract: Comparability of data over time and between laboratories is a key issue for consideration in the development of global databases, and more broadly for quality assurance in general. One mechanism that can be utilized for evaluating traceability is an inter-laboratory trial. This paper addresses an inter-laboratory trial conducted across a number of Australian and New Zealand isotope ratio mass spectrometry (IRMS) laboratories. The main objective of this trial was to determine whether IRMS laboratories in these countries would record comparable values for the distributed samples. Four carbon containing and four nitrogen containing compounds were distributed to seven laboratories in Australia and one in New Zealand. The laboratories were requested to analyze the samples using their standard procedures. The data from each laboratory was evaluated collectively using International Standard ISO 13528 ( Statistical methods for use in proficiency testing by inter-laboratory comparisons ). "Warning signals" were raised against one participant in this trial. "Action signals" requiring corrective action were raised against four participants. These participants reviewed the data and possible sources for the discrepancies. This inter-laboratory trial was successful in providing an initial snapshot of the potential for traceability between the participating laboratories. The statistical methods described in this article could be used as a model for others needing to evaluate stable isotope results derived from multiple laboratories, e.g., inter-laboratory trials/proficiency testing. Ongoing trials will be conducted to improve traceability across the Australian and New Zealand IRMS community. 相似文献
