How do officials of participating local governments assess the value of their involvement in performance‐comparison projects, including related costs and benefits? In this article, three prominent projects involving city and county governments are examined from the perspective of the participants themselves, revealing gaps between high expectations and subsequent results, but nevertheless suggesting an array of benefits for participants. 相似文献

Emotional, physiological and physical stress is associated with increased rates of cerebrovascular events and sudden deaths. The pathophysiology of stress-induced cardiomyopathy is not well understood. Proposed mechanisms for catecholamine-mediated stunning in stress cardiomyopathy include epicardial vasospasm, microvascular dysfunction, hyperdynamic contractility with midventricular or outflow tract obstruction, and direct effects of catecholamines on cardiomyocytes. Studies show evidence of significant heritable influences on individual responses to adrenergic stimulation. Data from such studies may be of help for a more accurate comprehension of clinical and morphological alterations of the heart. Irrespective of the cause, patients with the classic stress-induced cardiomyopathy morphology deserve special attention because this extensive distribution of wall motion abnormalities has implications for potential associated complications. Cardiac response may be significantly coupled to genetic differences at candidate loci that encode components of catecholamine biosynthesis, storage, and metabolic pathway. Given the role of the sympathetic nervous system in responses to acute stress, it is reasonable to explore whether genetically determined alterations in catecholamine system functions contribute to acute and chronic cardiovascular disorders such as stress-induced cardiomyopathy. 相似文献

Preliminary Data on the Role of Emotional Intelligence in Mediating the Relationship Between Psychopathic Characteristics and Detention Terms of Property Offenders 下载免费PDF全文

We present preliminary data on the role of emotional intelligence (EI) in mediating the relationship between psychopathy and detention term of authors of property crimes. We assumed that the detention term is an approximation of the severity of criminal behavior. A sample of 24 property offenders were individually administered a brief anamnestic interview, the Psychopathic Personality Inventory—Revised (PPI‐R), and the Mayer–Salovey–Caruso Emotional Intelligence Test (MSCEIT). Information concerning the detention term was obtained from prison records. A mediation model was applied to the data showing that offenders high in psychopathic traits (i.e., total PPI‐R score and Self‐centered dimension of PPI‐R) have a low level of ability EI and this is in turn negatively associated with the duration of their prison sentence. Results encourage the investigation of ability EI as a protective factor against the antisocial outcomes of psychopathic disorder. 相似文献

Hair testing for drugs of abuse: evaluation of external cocaine contamination and risk of false positives. 总被引:3,自引:0,他引:3
In some laboratories hair testing may be the main method for the evaluation of individual's drug history, however, compelling evidence supports the possibility that the presence of a small amount of drug in hair can derive from external contamination. The aim of the present study is to verify if a single external contamination with a small amount of cocaine will last sufficiently long to make a contaminated subject indistinguishable from active users, and if normal washing practices together with the decontamination procedures are sufficient to completely remove the external contamination. The results obtained using the decontamination methods suggested in literature demonstrate that significant concentrations of cocaine (>1 ng/mg) and moderate quantities of benzoylecgonine (generally <0.5 ng/mg) are still detectable up to 10 weeks after contamination. These results question the reliability of hair testing. In fact, even using the most sophisticated decontamination procedures it is not possible to distinguish a drug-contaminated subject from an active user. Thus, while a negative result excludes both chronic use and "contact" with drugs, a positive result cannot and must not be interpreted as a sure sign of drug addiction, but should be further confirmed by urine analysis. 相似文献

Body stuffer, sometimes called "mini packer", is the definition of someone who admits to or is strongly suspected of ingesting illegal drugs in order to escape detection by authorities, and not for recreational purposes or to transport the drug across borders. Cocaine is the drug most commonly involved in the body stuffer syndrome. Reported cases of body stuffer deaths are rare, however a fatality related to the ingestion of a plastic bag containing cocaine is described regarding a 17-year-old dealer. The authors describe how the cocaine body stuffer syndrome differs from the usual body packer. Histological and toxicological findings are examined and discussed for a better definition of this unique syndrome. 相似文献

Several studies have demonstrated that discriminant function equations used to determine the sex of a skeleton are population-specific. The purpose of the present research was to develop discriminant function equations for sex determination on the basis of 18 variables on the right and left talus and calcaneus in a modern northern Italian sample. The sample consisted of 118 skeletons (62 males and 56 females) from the Frassetto Collection (University of Bologna). The ages of the individuals ranged from 19 to 70 years. The results indicated that metric traits of the talus (in particular) and calcaneus are good indicators of sexual dimorphism. The percentage of correct classification was high (87.9-95.7%). In view of the differences among current Italian populations, we tested the validity of the discriminant function equations in an independent sample of individuals of different origin (northern and southern Italy). The accuracy of classification was high only for the northern Italians. Most southern Italian males were misclassified as females, confirming the population-specificity of discriminant function equations. 相似文献

This study examines whether community policing can build informal social control. Specifically, this paper assesses the impact of the Chicago Alternative Policing Strategy (CAPS) in Chicago neighborhoods. The data for this research are drawn from both the Community Survey of the Project on Human Development in Chicago Neighborhoods (PHDCN) and the CAPS Prototype Panel Survey. Bivariate and multivariate methods are used to analyze data gathered from 8782 residents nested within 343 neighborhood clusters. Initially, community policing was found to increase informal social control, but this effect was rendered non-significant after controlling for theoretically and empirically relevant variables. Several social (dis)organization variables, as well as satisfaction with policing services, yielded significant effects in a multilevel regression model. Further analysis found that the community policing effect on informal social control was mediated through satisfaction with the police. These findings indicate indirect support for the ability of community policing to build informal social control and suggest that general satisfaction with the police is important to neighborhood crime control strategies. 相似文献
