Indicators are currently being widely used in international policy making to substantiate analyses and justify decisions on the basis of their alleged scientific objectivity. This article analyses the role of indicators and statistics in the labelling and managing of ‘fragile states’, examining the powerful consequences of these classifications but also discussing the untraceable nature of numbers and the difficulties in attributing ownership of numerical claims and assigning responsibility for their many unforeseen impacts. Focusing on the education sector in Timor-Leste and on the World Bank’s Country Policy and Institutional Assessment (cpia) programme, the article shows how accountability and ownership are negotiated within the context of the g7+ group of self-labelled ‘fragile states’, encouraging an examination of the power relations involved. 相似文献

Although there is considerable evidence for the hypothesis that an efficient use of management techniques is the key to a good public service delivery, a lot of studies come to the conclusion that there is only partial, reluctant implementation or even a general lack of the use of such techniques by public managers. This paper examines the determinants for the use of quality management techniques in public sector organizations from six EU countries. It turns out that especially more organizational autonomy and result control appear to be of importance while, surprisingly, the combination of these variables leads to negative results. 相似文献

Many studies in the literature have highlighted the utility of virtual 3D databanks as a substitute for real skeletal collections and the important application of radiological records in personal identification. However, none have investigated the accuracy of virtual material compared to skeletal remains in nonmetric variant analysis using 3D models. The present study investigates the accuracy of 20 computed tomography (CT) 3D reconstruction models compared to the real crania, focusing on the quality of the reproduction of the real crania and the possibility to detect 29 dental/cranial morphological variations in 3D images. An interobserver analysis was performed to evaluate trait identification, number, position, and shape. Results demonstrate a false bone loss in 3D models in some cranial regions, specifically the maxillary and occipital bones in 85% and 20% of the samples. Additional analyses revealed several difficulties in the detection of cranial nonmetric traits in 3D models, resulting in incorrect identification in circa 70% of the traits. In particular, pitfalls included the detection of erroneous position, error in presence/absence rates, in number, and in shape. The lowest percentages of correct evaluations were found in traits localized in the lateral side of the cranium and for the infraorbital suture, mastoid foramen, and crenulation. The present study highlights important pitfalls in CT scan when compared with the real crania for nonmetric analysis. This may have crucial consequences in cases where 3D databanks are used as a source of reference population data for nonmetric traits and pathologies and during bone-CT comparisons for identification purposes. 相似文献

The problem‐solving capacity and problem‐generating potential of multilevel systems entail the need for the delegation of authority. When the problem concerned is about how to put an abstract policy concept into a practicable policy tool, the choice of the respective delegation trajectory depends on the policy models or the policy‐relevant knowledge that the respective political levels can supply. When regarding the European Union (EU) level as the starting point of knowledge creation and delegation trajectories, and concentrating on transaction costs, policy knowledge and models generated at the international level provide the most cost‐effective solution. Only when the international level is not able to provide further policy knowledge and innovation does the EU delegate its definitional authority, first downward to the member states and then sideways to EU agencies. We illustrate the plausibility of our dynamic understanding of multilevel governance by using Environmental Policy Integration as an example. 相似文献

The present study examined the longitudinal links between perceptions of family connectedness and body satisfaction in 1,774
(52% female) adolescents. Participants (10–15 years of age at Time 1) completed self-report measures at three measurement
occasions separated by 1 year each. Mean group difference results showed that both body satisfaction levels and perceived
levels of family connectedness decreased over 2 years for the whole sample. As expected, girls were generally less satisfied
with their bodies than boys, particularly in the older cohort. Structural equation modelling was used to assess stability
coefficients and cross-lagged effects, and longitudinal bidirectional effects between perceptions of family connectedness
and body satisfaction were found for girls, but not for boys. This result suggests that adolescent girls’ body satisfaction
is both affected by and a predictor of perceived family connectedness. 相似文献
