ABSTRACT

This article assesses the validity of normative claims on how civil servant values in East Asian and Western European administrations differ. By triangulating quantitative and qualitative survey data from a sample of Chinese (n = 508) and Dutch (n = 238) civil servants, we aim to answer two main research questions: “How and why do ideal-type and real-life rankings of civil servant values differ between Chinese and Dutch civil servants?” and “Do differences reflect administrative traditions of both countries?” Our findings demonstrate that similarities exceed differences between value rankings. Surprisingly, ideal-type value rankings are more similar than real-life rankings, with only a few idiosyncratic differences reflecting administrative traditions. Chinese civil servants perceive institutional and systemic factors as reasons for incongruence between ideal-type and real-life rankings, whereas Dutch civil servants emphasize meso-level factors such as organizational public management reforms. We theorize on our results and we provide suggestions for future research.  相似文献

Retrospective review of hanging suicides in individuals aged ≤ 17 years was undertaken at Forensic Science South Australia, Australia, over two 5-year periods: 1995-1999 and 2005-2009. Seven cases of hanging suicides were identified from 1995 to 1999, with a further 14 cases from 2005 to 2009, an increase of 100% (p < 0.001). Hanging accounted for 33.3% of all suicides in this age group (7/21) from 1995 to 1999, compared with 93.3% of the total number of suicides (14/15) in the second 5-year period. In contrast, Australian national data from 1998 and 2008 showed a 30% decrease in hanging suicides in the young, from one case/100,000 population in 1998 to 0.7 in 2008. Cluster suicides occur in the young and are often initiated by direct communication. As it is possible that Internet-based social sites may facilitate this phenomenon, investigations should include an evaluation of the victim's Internet access given the potential risk of similar actions by peers.  相似文献

In the analyzed period from 1998 to 2008, the autopsies performed at the Hamburg Institute of Legal Medicine included 13 cases in which an investigation for neonaticide had been initiated by the public prosecutor. The killed neonates showed a nearly equal distribution between both sexes. The most common method of neonaticide was suffocation. Most of the perpetrators were young, unmarried primipara with an average educational background. Almost all of them were suffering under psychological stress and had negated their pregnancy. In most cases, birth and neonaticide happened alone in their flat, and there was no medical attendance in any case. In the cases brought to court the women were charged with manslaughter (Section 212 German Criminal Code) and those found guilty were always granted a mitigated sentence pursuant to Section 213 Criminal Code.  相似文献

A decaying cadaver emits volatile organic compounds that are used by necrophilous and necrophagous insects in order to find their brood substrate. Although volatile organic compounds (VOCs) that are released by carcasses have been identified, little is known about the specific compounds that are used by these insects while searching for a brood substrate. Therefore, we have investigated the chemical ecology involved in the attraction of the necrophagous hide beetle Dermestes maculatus, which feeds as an adult and larva upon decomposing carcasses. Our aims have been to identify the responsible compounds in the odours of the carcass that are important for the attraction of the beetles. Furthermore, we have studied sex- and age-related differences in beetle attraction and tested whether the hide beetle can distinguish between various stages of decomposition by means of the emitted odours. Headspace collection of volatiles released from piglet carcasses (bloated stage, post-bloating stage, advanced decay and dry remains), coupled gas chromatography-mass spectrometry (GC-MS), gas chromatography with electroantennographic detection (GC-EAD) and bioassays were conducted to identify the volatiles responsible for the attraction of the beetles. Freshly emerged male beetles were attracted by the odour of piglets in the post-bloating stage (9 days after death; T(mean) = 27 °C) and the EAD-active compound benzyl butyrate. Statistical analysis revealed a higher relative proportion of benzyl butyrate in the odour bouquet of the post-bloating stage in comparison with the other stages. We therefore conclude that this compound plays an important role in the attraction of hide beetles to carcass odour. This underlines the potential use of D. maculatus for the estimation of the post mortem interval. The decomposition stage at which the female beetles are attracted to the odour of a cadaver remains unknown, as does the nature of this attraction. Pheromones (sexual or aggregation pheromones) might play an essential role correlated with their attraction to carrion and consequently with their attraction to the substrate for mating and ovipositioning.  相似文献

Building and extending on research on uncertainty management and voice and no-voice procedures, we examine how real personal uncertainty moderates the way in which people react to getting or being denied an opportunity to voice one??s opinions about decisions to be made. Specifically, results of two experiments show that conditions in which participants receive task-related feedback that induces personal uncertainty (versus conditions that produce more personal certainty) lead to stronger effects of voice and especially no-voice procedures on participants?? procedural fairness judgments (Experiments 1 and 2). Findings also reveal that in these conditions stronger effects of voice and particularly no-voice procedures can be found on participants?? anger about the way they have been treated, especially when participants are predisposed to react in intense terms to affect-related events (Experiment 2). Implications for the literature on uncertainty management and the social psychology of voice and no-voice procedures are discussed.  相似文献

This article intends to respond to a recent call (e.g., Zhang Global Crime 10(3):178–195, 2009; Brunovskis and Surtees International Migration 48(4):1–38, 2010) for more innovative studies and methodologies in order to move beyond the current discourse on human trafficking. We do so by describing three ethnographic fragments on the dynamics of (dealing with) sex trafficking within Europe. The concepts of ‘friction’ and ‘collaboration’ (Tsing Cultural Anthropology 15(3):327–360, 2000, 2005) are used to analyse these fragments. These concepts refer to creative processes that occur as people interact across differences. They give insight into how universal ideas on freedom and justice enable collaboration between parties involved in fighting human trafficking who do not necessarily share a common goal. We conclude that the presented method of ‘patchwork ethnography’ is useful in studying sex trafficking as it implies a strong focus on connections between ‘sites of diverse knowledge’, without losing sight of individual stories of people making those connections. ‘Patchwork ethnography’ is innovative and it allows researchers to expose and untangle the workings of the supposedly all-powerful phenomenon and the encompassing, uniform, hegemonic discourse surrounding human (sex) trafficking.  相似文献

This paper explains the observed combination of relatively low levels of democracy and positive attitudes towards it in the Muslim world. It argues that this democracy paradox is understandable from the perspective of the principle of diminishing marginal utility: people value highly that of which they have little. This reasoning implies, however, that surveys like the World Values Surveys (WVS) elicit circumstance-driven marginal preferences rather than culturally determined attitudinal traits. Empirical evidence showing that individuals living in undemocratic societies have much more favorable inclinations towards democracy supports our argument.  相似文献

Some scholars have found that mass immigration fuels the success of anti-immigration parties, whereas others have found that it does not. In this paper, we propose a reason for these contradictory results. We advance a set of hypotheses that revolves around a commonly ignored factor, crime. To test these hypotheses, we examine a setting where an anti-immigration party, the LPF, participated in simultaneous elections in all Dutch municipalities, which form a single constituency. According to our results, the impact of immigration rates on the individual vote for the LPF only manifests itself among those voters who are very ‘tough on crime’. In addition, we demonstrate that high local crime rates make an anti-immigration vote more likely, but only among voters who are very ‘tough on immigration’. This suggests that immigration and crime rates do not make all citizens more likely to cast an anti-immigration vote, but only those who perceive a link between the two issues. Thus, if one wishes to reduce anti-immigration leaders’ electoral support, countering their criminalization of immigrants may be a more fruitful strategy than trying to stop immigration – if at all possible.  相似文献
