An evaluation of primary-level healthcare undertaken in Tanzania 1989-91 found that district health managers felt powerless to address health care performance weaknesses, although the district is the unit to which government management functions have been decentralized. In order to understand the managers views, this article analyses the pattern of decentralization within the health system from their perspective. It reviews the hislorical development of government structures and the theory and practice of decentralization within Tanzania. The matrix of accountability for health care has become very confusing, with multiple and cross-cutting flows of authority within and between levels of the system. District health managers have limited authority to take management action, such as managing resources, in ways that would begin to address problems of inefficiency and poor quality of care within primary care. District health management also suffers from weak resource allocation and financial management piocedures. The main obstacles preventing more effective management are: resource constraints; conflicts between the demands for central control and local discretion; limited institutional capacity; and political and cultural influences over the implementation of decentralization. Evaluation of past experience suggests that future policy influencing the organizational structure of government health services must be developed cautiously, recognizing the critical importance of complementary action to develop both institutional capacity and political and economic support for the health system. 相似文献

The subject of missing persons is of great concern to the community with numerous associated emotional, financial, and health costs. This paper examines the forensic medical issues raised by the delayed identification of individuals classified as "missing" and highlights the importance of including dental data in the investigation of missing persons. Focusing on Australia, the current approaches employed in missing persons investigations are outlined. Of particular significance is the fact that each of the eight Australian states and territories has its own Missing Persons Unit that operates within distinct state and territory legislation. Consequently, there is a lack of uniformity within Australia about the legal and procedural framework within which investigations of missing persons are conducted, and the interaction of that framework with coronial law procedures. One of the main investigative problems in missing persons investigations is the lack of forensic medical, particularly, odontological input. Forensic odontology has been employed in numerous cases in Australia where identity is unknown or uncertain because of remains being skeletonized, incinerated, or partly burnt. The routine employment of the forensic odontologist to assist in missing person inquiries, has however, been ignored. The failure to routinely employ forensic odontology in missing persons inquiries has resulted in numerous delays in identification. Three Australian cases are presented where the investigation of individuals whose identity was uncertain or unknown was prolonged due to the failure to utilize the appropriate (and available) dental resources. In light of the outcomes of these cases, we suggest that a national missing persons dental records database be established for future missing persons investigations. Such a database could be easily managed between a coronial system and a forensic medical institute. In Australia, a national missing persons dental records database could be incorporated into the National Coroners Information System (NCIS) managed, on behalf of Australia's Coroners, by the Victorian Institute of Forensic Medicine. The existence of the NCIS would ensure operational collaboration in the implementation of the system and cost savings to Australian policing agencies involved in missing person inquiries. The implementation of such a database would facilitate timely and efficient reconciliation of clinical and postmortem dental records and have subsequent social and financial benefits. 相似文献

Prior research documents increased trauma symptoms associated with exposure to violence, primarily by examining types of violence separately. This study extends prior research by examining traumatic stress symptoms associated with two types of violence exposure, community violence and partner violence. A sample of 90 low-income African American women from an urban area completed measures assessing exposure to community violence, partner violence, and trauma symptoms. Exposure to community violence and partner violence were associated with increased reporting of trauma symptoms. Participants who experienced high levels of exposure to both types of violence reported more trauma symptoms than women who were exposed to only one type of violence or neither type of violence. The results suggest that the accumulation of exposures to violence is linked with greater distress. Thus, interventions with women exposed to violence should assess violence exposure in multiple domains and attend to the implications of multiple exposures to violence. 相似文献

A dual processing model of sexual harassment judgments predicted that the behavior of a complainant in a prior case would influence evaluations in an unrelated subsequent case. In the first of two experimental scenarios depicting social-sexual conduct at work, the female complainant's conduct was manipulated to be aggressive, submissive, ambiguous, or neutral. Half of the participants were asked to reflect upon the first scenario after reading it and before answering responsibility questions. The other half simply reviewed the scenario and answered the questions. When the complainant acted aggressively, her behavior in the first scenario caused men who reflected on the fact pattern to find less evidence of harassment. Most interestingly, an aggressive complainant observed in the first scenario caused participants (especially women) to rate lower the likelihood that a neutral complainant in a second independent case was the victim of gender discrimination. Across cases, men found less evidence of harassment than did women. 相似文献

The procedure used in this laboratory for removing and identifying contamination of hair specimens with drugs is demonstrated by its application to hair contaminated by various experimental models. The models include soaking; coating with drug followed by sweat conditions for 6 h; and soaking in a very high concentration of cocaine followed by storage and multiple shampoo treatments. A multi-part wash procedure along with a wash criterion is applied to all samples containing drug above the cutoff. The failure of the wash criterion is a signal that the sample may be positive due to contamination rather than use, and in the absence of other over-riding evidence, the sample would be considered to be negative for drug use. This Wash Criterion has also been tested with hair from subjects demonstrated to be drug users by one or more drug-positive urines; in these studies, all hair samples from demonstrated users passed the Wash Criterion test. 相似文献
