Most empirical research has shown that people working in the public sector perceive job security as more important than people working in the private sector, while the inverse is the case for job income. However, it is not known if these relationships hold globally while controlling for occupation and national context. We combine ISSP data from respondents in 25 countries with Hofstede’s cultural dimensions and World Bank data to examine whether the previous generally accepted claims hold while taking into account workers’ occupation, as well as national, cultural, and economic conditions. We find evidence that even when taking into account all these factors, government workers place a higher value on job security than private workers, but contrary to the generally accepted claim, we find no statistically significant difference between government and private workers in their high-income motives when taking the occupation and national context into the models.  相似文献

Despite the proliferation of research on public service motivation (PSM), fundamental questions about its origins continue to evade scholars: Is PSM driven by genetics, socialized through experiences, or both? If PSM is socialized, when does socialization occur? Answering these questions is critical for reconciling the state versus trait debate, and for assessing the validity of practical implications prescribed by PSM studies. Utilizing “nature's own experiment,” we adopt a classical twin design with 1035 twin pairs to identify how genetic heritability, a common environment, or unique environment and experiences can explain variation in PSM. Results show that PSM is heavily influenced by individuals' unique environments and experiences; not by genetics. This lends strong evidence to PSM's uniqueness as a motivational construct as related “other-regarding” concepts show sizeable genetic components. Finally, our results corroborate that PSM is a human resource with dynamic properties organizations can cultivate to enhance productivity in public service workforces.  相似文献

Conducted electrical weapons are designed to cause temporary electro-muscular incapacitation (EMI) without significant injury. The objective of this study was to assess the risk and cause of spinal injury due to exposure to a benchtop EMI device. Porcine subjects were exposed to 19 and 40 Hz electrical stimuli for a prolonged duration of 30 sec. X-ray imaging, necropsy, and accelerometry found that lumbosacral spinal fractures occurred in at least 89% of all subjects, regardless of the stimulus group, and were likely caused by musculoskeletal fatigue-related stress in the lumbosacral spine. Spinal fractures occurred in the porcine model at an unusually high rate compared to human. This may be due to both the prolonged duration of electrical stimulation and significant musculoskeletal differences between humans and pigs, which suggests that the porcine model is not a good model of EMI-induced spinal fracture in humans.  相似文献

Mirroring clinical guidelines, recent Performance Validity Test (PVT) research emphasizes using ≥ 2 criterion PVTs to optimally identify validity groups when validating/cross-validating PVTs; however, even with multiple measures, the effect of which specific PVTs are used as criterion measures remains incompletely explored. This study investigated the accuracy of varying two-PVT combinations for establishing validity status and how adding a third PVT or applying more liberal failure cut-scores affects overall false-positive (FP)/-negative (FN) rates. Clinically referred veterans (N = 114; 30% clinically identified as invalid) completing a six-PVT protocol as during their evaluation were included. Concordance rates were calculated across all possible two-and three-PVT combinations at conservative and liberal cutoffs. Two-PVT combinations classified 72–91% of valid (0–4% FPs) and 17–74% of invalid (0–40% FNs) cases, and three-PVT combinations classified 67–86% of valid (0–6% FPs) and 57–97% of invalid (0–24% FNs) at conservative cutoffs. Liberal cutoffs classified 53–86% of valid (0–15% FPs) and 39–82% of invalid (0–30% FNs) cases for two-PVT combinations and 46–75% of valid (3–27% FPs) and 60–97% of invalid (0–17% FNs) cases for three-PVT combinations. Irrespective of whether a two-or three-PVT combination or conservative/liberal cutoffs were used, many valid and invalid cases failed only one PVT (3–68%).Two-PVT combinations produced high FNs and were less accurate than three-PVTs for detecting invalid cases, though variable accuracy was found within both types of combinations based on the specific PVTs in the combination. Thus, both PVT quantity and quality are important for accurate validity classification in research studies to ensure reliability and replicability of findings. Applying more liberal cutoffs yielded increased sensitivity, but with generally higher FPs yielding problematic specificity, particularly for three-PVT combinations.  相似文献

Inverse Productivity or Inverse Efficiency? Evidence from Mexico   总被引:2,自引:0,他引:2  
Using a unique panel data set from rural Mexico, we find strong evidence of a negative relationship between farm size and both productivity and technical efficiency: large farms not only have a lower value of output per hectare than small farms, they also produce further from the efficiency frontier. Our findings suggest that, in spite of the ongoing transformation of agricultural supply chains and economists’ recommendations for small farmers to exit crop production, there may be sustained advantages for smallholder farms. Our analysis offers new insights into inverse-farm size relationship, the productivity–efficiency relationship, and the use of stochastic frontier techniques.  相似文献

We analyze the recent Flynn Report and assess its implications for the future of military intelligence in Afghanistan. In particular, we argue that the report seeks to expand the substantive tasks of the military intelligence practitioner, while collapsing non-trivial aspects of existing organizational hierarchies. We argue that implementation of the Flynn Report's proposals would match poorly with the traditional nature of military intelligence and the realities of human resources constraints in the military. Further, the resulting scale of unfiltered data such a system would produce might serve to overwhelm rather than assist decision-makers. Finally, we conclude that the problems expressed in the Flynn Report should not be traced to the military intelligence apparatus per se, but rather to the inability of US political leadership to map out a clear vision for current operations – both in Afghanistan, and in the counterinsurgency environment in general.  相似文献

Despite the cessation of a variety of governmental organisations, policies and programmes in the UK throughout the 1980s and 1990s, the termination concept which emerged during the late 1970s remains heavily under utilised. This is attributed partly to the effects of the same incremental practices which termination was designed to solve; partly to the difficulties of distinguishing the categories of ‘termination’ from ‘succession’ ; and partly to Kaufman's assertion that organisational survival was a matter of chance, and therefore not fruitful to study. Academic interest in governmental cessations remains firmly rooted in the termination of organisations; much less attention has been paid to the ending of policies and programmes. Management science research can be used to challenge assertions about the lack of pattern in organisational survival, and the way in which political science has operationalised the concept of incerementalist, suggesting the applicability of semi rationalist techniques in an incrementalist world. Using a hierarchical reformulation of de Leon's 1978 categorisation of governmental functions, organisations, policies and programmes it is here suggested that ‘termination’ and ‘succession’ are distinct. In doing so, the aim is to demonstrate the practical utility of the termination concept, both for analysis, and for practitioners whose interest is centred on the opportunity cost savings which cessations can make available.  相似文献
