We use case study methodology to examine the degree of cooperation and coordination among organizations providing mental health care to older persons. Mail surveys and in‐depth interviews were employed to gather data from human service organizations in one relatively rural county of Upstate New York. We find that organizations that are older and provide larger numbers of services tend to have a higher degree of integration with other organizations. There is little evidence of formal coordination of services. Informal cooperation, at least on an ad hoc basis, is common, though. Older persons with chronic mental health problems are relatively well served by the system. Older persons whose mental health problems are associated with the aging process are not well served by the system. The growth of mental health managed care has increased competition among many organizations, further fragmenting a weakly integrated system.  相似文献

Youth living in impoverished urban neighborhoods are at risk for becoming hopeless about their future and engaging in violent behaviors. The current study seeks to examine the longitudinal relationship between social connections, hopelessness trajectories, and subsequent violent behavior across adolescence. Our sample included 723 (49% female) African American youth living in impoverished urban neighborhoods who participated in the Mobile Youth Survey from 1998 through 2006. Using general growth mixture modeling, we found two hopelessness trajectory classes for both boys and girls during middle adolescence: a consistently low hopelessness class and an increasingly hopeless class with quadratic change. In all classes, youth who reported stronger early adolescent connections to their mothers were less hopeless at age 13. The probability of later adolescent violence with a weapon was higher for boys and was associated with the increasingly hopeless class for both boys and girls. Implications for new avenues of research and design of hope-based prevention interventions will be discussed.  相似文献

This article evaluates state-sponsored terrorism as a principal-agent issue. More often applied to the study of licit national or international institutions as a way to improve their governance, we argue that applying principal-agent analysis to illicit relationships such as those between states and terrorist agents is an equally fruitful application, though one with different objectives. Rather than being used as a tool to improve governance, applying principal-agent analysis to illicit relationships such as state-sponsored terrorism may point to areas of susceptibility and thus inform more effective counterterrorism strategies. In this article, we explain why states delegate to terrorist groups, how they seek to control their agents, and the tensions in the relationship, both generally and through specific reference to Iran's sponsorship of Hizballah, Syria of various Palestinian groups, and the Taliban of al-Qa'ida. This analysis yields propositions about the conditions under which states are likely to delegate to terrorist groups and specific recommendations on how principal-agent problems of these illicit relationships may be used in practice to combat terrorism.  相似文献

As the Bush presidency draws to a close, the foreign policy community is taking stock of contemporary U.S.-Northeast Asian relations, assessing the challenges and opportunities that are likely to confront the next administration. China presents both in abundance, as reflected in ongoing tensions and misunderstandings in the Sino-American bilateral relationship. This article assesses the prospects for Washington to improve its relations with China through the mechanism of “track two” diplomacy. First, we expand on the track two concept by examining its main components and functions with illustrative examples. We extend the existing conceptualization of track two beyond its traditional conflict resolution functions and develop an account of it as a mechanism for policy coordination and the reorientation of regional dynamics from conflict to cooperation. Second, we identify major areas of U.S. interest in Northeast Asia and show how track two diplomacy might usefully be pursued within these contexts. Our analysis culminates with recommendations on how the Unites States should apply track two strategies in its relations with China.  相似文献

Research has demonstrated that pilots contain multiple shifting purposes, not all of which relate to simple policy testing or refinement. Judging the success of policy pilots is therefore complex, requiring more than a simple judgment against declared goals. Marsh and McConnell provide a framework against which policy success can be judged, distinguishing program success from process and political success. We adapt Boven's modification of this framework and apply it to policy pilots, arguing that pilot process, outcomes and longer-term effects can all be judged in both program and political terms. We test this new framework in a pilot program in the English National Health Service, the Vanguard program, showing how consideration of these different aspects of success sheds light on the program and its aftermath. We consider the implications of the framework for the comprehensive and multifaceted evaluation of policy pilots.  相似文献

This research is motivated by a change in Florida that affected assisted living facilities (ALFs) by removing the property tax exemptions for those operated by nonprofit organizations. As such, this paper addresses two research questions: (1) Are there systematic differences between Florida's for-profit- and nonprofit-designated ALFs in terms of operations and service provision? (2) What was the impact, if any, of losing and regaining their property tax exemptions on the operations of Florida's nonprofit ALFs? We use data from the Florida Agency for Health Care Administration to conduct difference of means testing for-profit versus nonprofit ALFs, as well as annual financial data of each ALF property owners' IRS Form 990 from the National Center for Charitable Statistics Core Files and parcel-level property data from the state of Florida to conduct regression analysis using three different dependent variables measuring various components of nonprofit ALF operations. We find that nonprofit ALFs have greater legitimacy in service delivery than for-profits, as nonprofit ALFs have higher service capacity, quality, and variety than for-profit ALFs in Florida. In addition, property tax exemptions for nonprofit ALFs in Florida decrease total expenses and increase officer compensation.  相似文献

New York State's current lack of legislation criminalizing the threat of revenge porn allows repetitive, invasive, and embarrassing attacks on the morality and sexuality of victims. This can have a severe impact on survivors of domestic violence who are prevented from leaving dangerous situations by threats of dissemination. Victims of revenge porn and domestic violence often face isolation, threats of violence, and thoughts of suicide. This Note proposes that threats of revenge porn become family offenses under the New York Family Court Act § 812.  相似文献

In forensic intelligence-gathering it would be useful to be able to estimate the size of a perpetrator's foot from a standing bare footprint found at the scene of crime. Currently, the advice is to add a fixed amount to the length of the footprint (typically 1.5 or 2.0 cm), but there is little evidence for this approach. This study used measured footprint and actual foot lengths from 146 participants from the white British student population of a University in the UK. Data were analysed using multiple regression with foot length as the dependent (outcome) variable and footprint length and sex as the independent variable/factor respectively. Sex was not a significant predictor. The regression equation for the best estimate of the foot length is 19.89 + 0.95 × print length ± 8 mm.  相似文献

This article explores and shares the learning from two of Cafcass’ innovative dispute resolution pilot programs. The programs aim to improve outcomes for families against the backdrop of rising private law demand in England, while keeping the child at the center. The Positive co‐Parenting Programme pilot provides a structured intervention to reduce conflict and promote timely resolution for children and families in complex cases. The Support with Making Child Arrangements pilot explores whether the provision of a package of support to parents ahead of the first court hearing can help them come to safe agreements about their children without the need for court intervention.  相似文献
