Training of police officers is important in order to maintain an effective law enforcement community. The present study investigates the mediating effect of motivation for operational duties on the relation between operational self-efficacy and performance satisfaction as well as perceived strain during a simulated operational scenario. Moderating effects of personality hardiness on the same relations were also investigated. Personality hardiness as a moderator was found only for the relation between operational self-efficacy and performance satisfaction. A positive effect was found for high hardy subjects, and a negative effect was found for low hardy subjects. The results also showed a mediating effect of motivation for operational duties on both performance satisfaction and perceived strain. This could have implication for selection and training in the police force. 相似文献
Field experiments have become popular in public administration. By allowing for the identification of causal effects in realistic settings, field experiments may become central in several research agendas of relevance to the field. Conducting field experiments is difficult and problems often occur along the way. However, researchers new to the method have few resources in public administration to consider the problems that arise when conducting field experiments. This systematic review identifies 42 field experiments in public administration and serves as an introduction to field experiments in public administration. The article discusses how field experiments developed over time and highlights trends in field experimentation in public administration. It then discusses issues to consider when designing field experiments. Among these are costs, practicality, ethics, and validity. Finally, the authors suggest a future research agenda for public administration field experiments. 相似文献
Public managers’ decisions are affected by cognitive biases. For instance, employees’ previous year's performance ratings influence new ratings irrespective of actual performance. Nevertheless, experimental knowledge of public managers’ cognitive biases is limited, and debiasing techniques have rarely been studied. Using a survey experiment on 1,221 public managers and employees in the United Kingdom, this research (1) replicates two experiments on anchoring to establish empirical generalization across institutional contexts and (2) tests a consider-the-opposite debiasing technique. The results indicate that anchoring bias replicates in a different institutional context, although effect sizes differ. Furthermore, a low-cost, low-intensity consider-the-opposite technique mitigates anchoring bias in this survey experiment. An exploratory subgroup analysis indicates that the effect of the intervention depends on context. The next step is to test this strategy in real-world settings.相似文献
In contrast to typical autoerotic fatalities, when death is due to asphyxia mostly by mechanical compression of the neck, atypical autoerotic accidental deaths (AADs) involve sexual self-stimulation by other means such as electrocution or inhalation of chemical agents. Especially in lethal cases of volatile substance abuse (VSA), a differentiation between suicide or sexually or nonsexually motivated accident is often complicated in practical casework. Considering the small number of AADs involving chemical substance abuse reported in the literature, the number of unreported cases seems to be very high. We report about 5 lethal cases of VSA; analysis was performed using headspace solid-phase microextraction (HS-SPME) and gas chromatography-mass spectrometry (GC/MS). When headspace sampling is not performed at autopsy, the analysis of volatile substances can be very complicated. In 2 cases, an AAD was diagnosed considering findings at the scene, reconstruction of the event, and discussion of the circumstances of the death. These findings demonstrate the importance of VSA in atypical autoerotic asphyxia. Therefore, in cases of suspected lethal inhalational intoxications, as a matter of principle, headspace asservation should be performed at autopsy and an autoerotic motivational background should be taken into consideration for differential diagnosis. 相似文献
In contrary to "physical restraint", describing a fixed body position due to external devices, "positional restraint" is defined as an abnormal body position, resulting from accidental fixation under unfortunate circumstances. We report on a remarkable case of positional asphyxia of an alcoholised young man after a fall down a staircase. On external examination, the body showed petechiae of the conjunctivae and oral mucosa, abrasions on the left zygomatic region and scratch marks, respectively. Neither broken fingernails, etc. nor signs of external violence against the neck were found. Autopsy revealed haemorrhages in the praevertebral cervical musculature and Simon's sign. Haemorrhagic pulmonary edema and cerebral edema were observed; blood alcohol concentration: 2.60 g/l, urine alcohol concentration: 3.26 g/l. As cause of death, positional asphyxia after blunt head trauma has to be considered as well as lethal ethanol intoxication. To us, alcoholisation attributed to the fall and together with unconsciousness following blunt head trauma circumvented self-rescue efforts, and therefore, aggravated the potentially lethal impact of positional restraint. 相似文献
