The need to attract and retain a high calibre cadre of public servants today has resulted in a renaissance of interest in public service motivation (PSM) within public management literature. This article outlines a study of PSM with graduate employees within an Australian public sector. The study extends our understanding of PSM by adopting a longitudinal, mixed method design, including surveys and individual interviews, to consider the effects of socialisation on levels of PSM. Results show an organisation's mission and values do not affect individual PSM while work type and communication style is vital and organisational socialisation can provide a negative influence.  相似文献

Despite weak partisanship and considerable political change in the wake of the 2002 election, three‐quarters of Brazilian voters supported a presidential candidate in 2006 from the same party they had backed in 2002. This article assesses the factors causing both electoral stability and electoral change with a transition model, a model testing whether the effects of respondents' evaluative criteria depend on their initial vote choices. Social context—personal discussion networks, neighborhood influences, and the interactions of social networks and municipal context—is the major force promoting stability and change, while the impact of partisanship is limited to a small share of voters.  相似文献

It is a common misconception that the amount of explosive is the chief contributor to the quantity of vapor that is available to trained canines. In fact, this quantity (known as odor availability) depends not only on the amount of explosive material, but also the container volume, explosive vapor pressure and temperature. In order to better understand odor availability, headspace experiments were conducted and the results were compared to theory. The vapor-phase concentrations of three liquid explosives (nitromethane, nitroethane and nitropropane) were predicted using the Ideal Gas Law for containers of various volumes that are in use for canine testing. These predictions were verified through experiments that varied the amount of sample, the container size, and the temperature. These results demonstrated that the amount of sample that is needed to saturate different sized containers is small, predictable and agrees well with theory. In general, and as expected, once the headspace of a container is saturated, any subsequent increase in sample volume will not result in the release of more vapors. The ability of canines to recognize and alert to differing amounts of nitromethane has also been studied. In particular, it was found that the response of trained canines is independent of the amount of nitromethane present, provided it is a sufficient quantity to saturate the container in which it is held.  相似文献

Reye's syndrome. A review from the forensic viewpoint   总被引:1,自引:0,他引:1  
Reye's syndrome, encephalopathy and fatty change in the liver and other viscera, typically occurs suddenly in infants and children recovering from a viral illness, particularly influenza or varicella. Its rapid clinical course may suggest a drug-related insult and the differential diagnosis includes a variety of toxins. There are grounds for suspicion that exogenous substances--including aspirin--may be cofactors with recent viral illness in the syndrome's pathogenesis. For these reasons, medical examiners may be called upon to rule the diagnosis in or out, to assess the possibility of direct toxic injury, or to document presence or absence of possible cofactors. With these tasks in mind, this review summarizes the diagnostic, pathologic, and laboratory findings of Reye's syndrome and considers the roles of viral infection, heritable predispositions, and exogenous toxins in its causation. It singles out salicylate treatment for special considerations as a possible cofactor, and concludes with a suggested approach to the forensic medical investigation of possible cases of Reye's syndrome.  相似文献

Judicial instructions (traditional American Law Institute vs. Guilty But Mentally Ill [GBMI]) were manipulated within an insanity defense vignette portraying a highly psychotic defendant. Construals were highly predictive of verdicts in both instructional conditions. Instead of influencing case construals, the GBMI option seems to operate by increasing respondents' decisional thresholds for insanity and guilty verdicts, creating a collapsing effect such that few such verdicts are rendered. Between-instruction comparisons reveal that the construals of respondents who choose insane and guilty verdicts are considerably more homogeneous and extreme under the GBMI conditions. Results suggest that many respondents intend their GMBI verdicts to signify diminished blame and punishment, indicating that such verdicts entail cognitive compromises that reflect both the thresholdraising effects and also probable confusion about the jurisprudential meaning of a GBMI verdict.This article is an expanded version of a paper entitled Insanity case construals are not simply verdict justification effects, which was presented at the 99th annual convention of the American Psychological Association at San Francisco, August, 1991. We would like to thank Linda Roberts, Norman Finkel, and the anonymous reviewers for their comments on an earlier version of this paper. Support for this research was provided in part by a grant from the Baldy Center on Law and Social Policy at the State University of New York at Buffalo.  相似文献

A major reason the quality of cost‐benefit analysis (CBA) varies widely is inconsistent use of the social discount rate (SDR). This article offers guidance about the choice of the SDR. Namely, we recommend the following procedures: If the project is intragenerational (does not have effects beyond 50 years) and there is no crowding out of private investment, then discount all flows at 3.5 percent; if the project is intragenerational and there is some crowding out of investment, then weight investment flows by the shadow price of capital of 1.1 and then discount at 3.5 percent; if the project is intergenerational and there is no crowding out of investment, then use a time‐declining scale of discount rates; if the project is intergenerational and investment is crowded out, then convert investment flows during the first 50 years to consumption equivalents using a shadow price of 1.1, and then discount all of these flows at 3.5 percent, and discount all flows after the 50th year using time‐declining rates. We then compare current discounting practices of U.S. federal agencies with our estimates. Consistent use of the recommended rates would eliminate arbitrary choices of discount rates and would lead to better public sector decision‐making. © 2004 by the Association for Public Policy Analysis and Management.  相似文献

Government‐funded training programs in the United States have often been subject to rigorous evaluation. Indeed, many of these programs have been evaluated with random assignment, although sophisticated quasi‐experimental methods have also been used. Until very recently, however, there has been little systematic attempt to use the cumulative information vested in these evaluations to attempt determine which kinds of programs work best in which setting and with respect to which types of client. Meta‐analysis—a set of statistical procedures for systematically synthesizing findings from separate studies—can, in theory at least, address these and other topics that evaluation of individual programs cannot. This article discusses the steps in conducting such a synthesis, summarizes the results of three recently conducted meta‐analyses of training and welfare‐to‐work programs, identifies limitations to the meta‐analytic approach, and considers ways in which some of these limitations can be overcome.  相似文献

Since 1968 more than thirty-five social policy experiments have been conducted in the United States. During this period through 1976 these experiments were generally long-term, large-scale tests of major new programs; thereafter, experiments became markedly more modest in scope. Although hundreds of millions of dollars were spent on the earlier programs, the experiments probably had only a negligible impact on policies. This result stemmed from a variety of factors: Social testing actually tends to exert a conservative influence on policymaking; and the time required to complete experiments and interpret results is often incompatible with the needs of policy makers. In addition, test results are often not effectively communicated to Congress, the administration and the public, and even when the results are conveyed, policy makers are frequently skeptical about the soundness of the methodologies employed. If recent experimental programs are to exert more influence on policymaking, program oficials will need to address these dificulties.  相似文献
