Based on a national survey of police chiefs with a follow-up focus group, this article discusses budgetary strategies that police departments used to be successful in budgeting. The strategies include: using crime and workload data judiciously; capitalizing on sensational crime incidents; effectively getting the message out; carefully mobilizing interest groups; strategic planning; playing the federal grants game; working closely with the chief executive and elected officials; and involving all departmental staff levels in budgeting. 相似文献

Plastic fingerprint impressions found at crime scenes are often too delicate for collection, leaving photography as the best option for documentation. However, traditional photography techniques can be inadequate in documenting minute 3-D details due to limitations of the camera and lighting conditions. This study investigated the feasibility of applying commercially available structured-light 3-D scanners in the documentation of plastic prints. Attempts were made to develop a procedure to extract curvature features from 3-D scanned fingerprints and flatten the friction ridge features into two-dimensional (2-D) images to allow direct comparison with the traditional photography in the CSIpix® Matcher and NFIQ 2.0 software. Two 3-D scanners were evaluated a Dentsply Sirona inEos X5® and an Artec Space Spider. In this study, 3-D scanners demonstrated robustness as well as efficiency in the collection of plastic fingerprint impressions in select substrates. One of the developed methods utilizing a discrete geometry operator and convexity features outperformed traditional photography, achieving higher software detection scores in minutiae count and match quality, while traditional photography could not always capture enough high-quality minutiae for comparisons, even after digital enhancement. 相似文献

Self-harm and suicide websites have been heavily criticized both in the literature and the wider media, despite the fact that very little is known about them. To date, no study has interviewed users of these sites about them. This qualitative study aims to explore the accounts of young adults who engage in self-harming and suicidal behaviors and use websites dedicated to these issues, in order to develop a broader understanding of these websites and to identify potential implications for future research. In-depth interviews were conducted via e-mail with 10 participants, who were recruited directly from self-harm and suicide websites. Using discourse analysis, we identified three main ways in which participants wrote about the sites. They constructed them as sources of empathy and understanding, as communities, and as a way of coping with social and psychological distress. These discourses gave users access to important, socially valued identities, such as being understood, belonging to a community and coping with their problems. If health professionals and researchers hope to understand people who use self-harm and suicide websites, and engage them in their services, they must take a more balanced view and not focus solely on the possible risks associated with using such sites. 相似文献

Person-centered approaches to understanding delinquent and criminal careershave identified several distinct pathways or patterns of delinquent behavior(Gorman-Smith et al., 1998; LeBlanc and Kaspy, in press; Loeber et al.,1991; Loeber et al., 1993). In addition, research suggests that there maybe etiological variations that correspond to these different pathways(Gorman-Smith et al., 1998). That is, there may be different configurationsof risk factors associated with different types of delinquent and criminaloffending. If this is so, understanding these relations can have importantimplications for intervention and prevention. However, there have been fewstudies that examine how the configuration of risk factors may vary inrelation to different delinquency pathways. The current study brings aperson-centered analysis to examine how patterns of family functioningrelate to patterns of offending. In addition, this study contextualizesthese relations by examining how these relations vary as a function ofcommunity setting. This study expands upon previous research that hasidentified four basic patterns of delinquent behavior among a sample ofminority male adolescents living in poor urban neighborhoods (Gorman-Smithet al., 1998). 相似文献

Previous theoretical and empirical research findsenhanced veto authority has little systematic effecton level of spending. This paper takes a new tact,examining the effect of veto power on thecentralization of governmental services. It proposesand tests a model of federalism in which differenttypes of veto authority lead to differing degrees ofcentralization when the executive and legislature havedisparate preferences over the level of governmentthat should provide services. Empirical resultsindicate governors in the United States use enhancedveto authority to centralize state and localgovernment spending. 相似文献

Spontaneous coronary artery dissection is a rare cause of acute myocardial infarction and sudden death. It typically, but not always, occurs in healthy postpartum women without traditional risk factors for atherosclerosis. Moreover, the site of dissection usually involves the proximal, major coronary arteries: left main coronary artery and/or the left anterior descending artery, and in men, more often the right coronary artery. We report a case of sudden death caused by dissection of the obtuse marginal branch of the left circumflex artery, in a 49-year-old man, a very rare site of fatal coronary dissection. 相似文献

This paper discusses the manifestations and correlates of depressive affect disorders in adolescents. It begins with some definitions and a discussion of the concept (from adult psychiatry) of depression and depressive disorders. The clinical picture of depressive disorders in adults is described, and the interrelationship is considered between them and the depressive disorders of adolescents and prepubertal children. Data are discussed regarding the external validity of adolescent depressive disorders (including their familial and biological correlates, their course and treatment outcome). Finally, the relevance of these data is summarized with regard to the process of establishing a diagnosis of a depressive disorder in adolescents.Received M.D. from Washington University. Research interests are the diagnosis and assessment of childhood psychopathology, especially Attention Deficit Disorder and Depressive Disorders.Received Ph. D. from UCLA. Research interests are language and learning disorders and childhood psychopathology. 相似文献
