In recent years, governments have introduced several reforms, often adopting management mechanisms traditionally associated with the private sector. This article looks specifically at the impact of decision‐rights decentralization, along with accountability mechanisms, on performance. Twenty public sector organizations, experiencing a shift from rule‐based to outcome‐based control mechanisms and benefiting from different levels of autonomy and decision margins, were studied. Results show a link between the degree of power delegation and increased organizational performance. The units benefiting from greater freedom with respect to financial and human resources decisions experienced the greatest margin of performance increase. These findings underline the importance of considering the level at which measures are defined and the elements included in the measurement mechanisms (outcomes or rules). 相似文献

Forensic entomotoxicology studies the usefulness of insects as alternative toxicological samples. Use of insects as alternative matrix for drug detection is well documented and recommended when conventional matrices such as blood, urine or internal organs are no longer available. However, several limitations of entomotoxicology have been highlighted, especially concerning interpretation of the drug concentrations in insects on human forensic cases. In addition, the lack of knowledge in pharmacokinetic of drugs in insects, large variability of experimental set-up and toxicological analysis compromise the utility of this science. This review focuses on the current knowledge of factors influencing drug detection in insects. Reasons for the current limitations, but also recommendations for future research are discussed and proposed in this paper. 相似文献

Coding non-manifesto documents as if they were genuine policy platforms produced at election time clearly raises serious issues with error when these codings are used in the standard manner to estimate left-right policy positions. In addition to the long term solution of improving the document base of the Manifesto Project identified by Gemenis (2012), we argue that immediate gains in manifesto-based estimates of policy positions can be realised by using the confrontational logit scales from Lowe et al. (2011), which addresses the problems of scale content and scale construction that are exacerbated by but not unique to the problems found in proxy documents. 相似文献

Individuals often need to negotiate how to distribute jointly produced goods—equally (e.g., 50:50) or equitably (e.g., proportionally
to their contributions). We examined whether people have stable preferences, or whether they switch between equality and equity
in different situations. Pairs of anonymous participants first produced a common pie, and then distributed it in an ultimatum
game. Results suggest that individuals apply different justice principles depending on their contribution. When they produced
less than 50%, proposers divided the pie equally. However, when they produced more than 50%, their offers fell between equality
and equity. Responders’ ratings of fairness and satisfaction varied similarly; with low production, equality was preferred,
whereas with high production, equity was preferred. Nevertheless, equal and equitable offers were generally accepted, and
only outright unfair offers were rejected. This suggests that individuals are relatively flexible about which justice principle should be applied, but punish proposers whose offers violate both principles. 相似文献

Two simulated scenes of crime have been studied. Soil traces adhering to boots, sport shoes and tissues have been compared with control samples using particle size analysis. Comparisons of percentage of particles per class interval and multivariate analyses were used to determine how the size distribution of each suspect sample varied compared to the original distribution. A loss of coarse fractions characterized most of the suspect samples even though they were derived from soils having different distributional patterns. However, the differences between control and suspect samples were found to be more important for soils dominated by extreme size classes than for soils rich in medium size particles. The differences among soil samples from the same source were found to be restricted to the extreme size classes. The finding of significant differences within size classes ranging from 1 to 0.063 mm should be then considered as a dissimilarity sign between trace sample and hypothetic control soil. 相似文献

Despite the huge number of possible seat distributions following a general election in a multiparty parliamentary democracy, there are far fewer classes of seat distribution sharing important strategic features. We define an exclusive and exhaustive partition of the universe of theoretically possible n‐party systems into five basic classes, the understanding of which facilitates more fruitful modeling of legislative politics, including government formation. Having defined a partition of legislative party systems and elaborated logical implications of this partition, we classify the population of postwar European legislatures. We show empirically that many of these are close to critical boundary conditions, so that stochastic processes involved in any legislative election could easily flip the resulting legislature from one type to another. This is of more than hypothetical interest, since we also show that important political outcomes differ systematically between the classes of party systems—outcomes that include duration of government formation negotiations, type of coalition cabinet that forms, and stability of the resulting government. 相似文献
