An important and unresolved issue central to the study of government performance is how the actions of managers and the nature of organizations affect the cost of public services. This paper presents an empirical analysis of fire departments that estimates the influence of managerial choices on per capita spending within a simultaneous public production system. It does so by refining a theoretical cost model from the field of public management to include fundamental dimensions of government organizations and administration. Two‐stage least squares regression analysis is then employed to examine the fire protection case. The results of the analysis substantiate the intuition that managerial practices and decisions influence the cost of a public service. They show that the cost of fire protection depends significantly on the outcomes of a department's fire prevention and suppression activities, some key aspects of a department's management practices, the configuration of its workforce and equipment, its legal structure, and factors in its external environment. © 2004 by the Association for Public Policy Analysis and Management. 相似文献

Abstract. This article presents feminist comparative policy (FCP) as a new field of study. It argues that FCP scholars have successfully developed a distinct approach to doing political research and a significant scientific community which follows this approach. In doing so, FCP scholars, particularly since the early 1990s, have moved this area of study into a new stage of institutionalization and influence. These achievements are documented in a discussion of first, the development and major features of the FCP approach and second, the individuals and research infrastructure that comprise the FCP community. The conclusion considers the successes of FCP in the context of speculations about its contributions to non feminist political science. 相似文献

Several researchers in the 1950's proposed that hypernatremia causes water to leave brain cells, shrinking the brain, thus tearing the bridging veins and resulting in subdural hematomas. Although the old literature suggests mechanisms linking the two in a cause and effect relationship, there is controversy as to whether hypernatremia leads to subdural bleeding or whether the reverse is true. This issue is important for forensic pathologists who must distinguish natural disease from trauma. An etiologic link between hypernatremia and subdural hematomas was suggested recently, and was proposed originally before Kempe's 1962 paper "The Battered Child Syndrome" which widely disseminated the concepts of child physical abuse, and of subdural bleeding resulting from non-accidental injury. Our study is a multifaceted investigation of infants which includes: a literature review, retrospective chart reviews of both living and deceased hypernatremic infants, a retrospective review of infants hospitalized with subdural hematoma, and a prospective collection of head injured, hypernatremic children. We conclude that hypernatremia, if present in association with subdural hemorrhage, is most likely secondary to intracranial pathology, and that hypernatremia often develops in critically ill infants suffering from a variety of medical conditions. 相似文献

Romantic Relationship Aggression and Attitudes in High School Students: The Role of Gender,Grade, and Attachment and Emotional Styles 总被引:3,自引:0,他引:3

Use of aggressive behaviors in adolescent romantic relationships, the endorsement of attitudes that promote such behaviors, and the extent to which attachment and emotional styles are related to these behaviors and attitudes were examined in 254 high school students. In general, aggressive behaviors and attitudes were not common. As expected girls were somewhat more likely to report being the perpetrator of physical aggression and boys were somewhat more likely to endorse the acceptance of aggression and dysfunctional sexual attitudes. For girls, a less secure relationship with best friends and lower levels of shame and guilt were related to the use of aggression in romantic relationships and endorsing less healthy attitudes about these relationships. For boys, externalizing responsibility for harm to others was related to using physical aggression in romantic relationships and lower levels of guilt and shame were related to the justification of sexual aggression. Intervention implications discussed include the need to employ programs that are grounded in the nature of adolescent relationships where aggression is more often mutual between partners, and the potential benefit of targeting emotional styles. 相似文献

Kanter's tokenism theory argues that once tokens reach a tipping point of 15 percent representation in the work place, they begin to experience fewer work place problems. This study tested this assertion using a survey of eighty-seven officers in a midwestern municipal police agency, where female officers constituted over 17 percent of the total sworn patrol officers. The three dimensions of tokenism were examined quantitatively to ascertain differences between male and female officers. On two of the dimensions, there were no differences between male and female officers, but the third dimension showed that female officers still perceived their work place differently from male officers. Only partial support of Kanter's theory was found. It was evident that even in this department, however, females still felt like they stood out and were underestimated by their peers. The findings also suggested that tokenism is more complex than a “numbers game,” and that quantitative examinations alone might not fully explain the myriad aspects of tokenism. 相似文献

Y-chromosomal short-tandem repeat (Y-STR) amplification has been used in forensic casework at the Bureau of Criminal Apprehension (BCA) Forensic Science Laboratory since 2003. At that time, two separate amplifications were required to type the SWGDAM recommended loci (DYS19, DYS385a/b, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS438, and DYS439). The Yfiler kit coamplifies these loci as well as DYS437, DYS448, DYS456, DYS458, DYS635, and Y GATA H4. The Yfiler kit was validated following the internal validations outlined in the SWGDAM revised validation guidelines. Our studies show that 0.125 ng of male DNA will generate a complete 17 locus profile and that as little as 0.06 ng of male DNA yields an average of nine loci. In the male-male mixtures, a complete profile from the minor component was detected up to 1:5 ratio; most of the alleles of the minor component were detected at a 1:10 ratio and more than half the alleles of the minor component were detected at a 1:20 ratio. Complete YSTR profiles were obtained when 500 pg male DNA was mixed with female DNA at ratios up to 1:1000. At ratios of 1:5000 and 1:10,000 (male DNA to female DNA) inhibition of the YSTR amplification was evident. The YSTR results obtained for the adjudicated case samples gave significantly more information than the autosomal results. Our studies demonstrate that the Yfiler kit is extremely sensitive, does not exhibit cross-reactivity with female DNA, successfully types male DNA in the presence of overwhelming amounts of female DNA and is successful in typing actual forensic samples from adjudicated cases. 相似文献

At ratios of 1:5000 and 1:10,000 (male DNA to female DNA) inhibition of the YSTR amplification was evident. The YSTR results obtained for the adjudicated case samples gave significantly more probative information than the autosomal results.
