This article contributes to the growing body of literature on government transparency by developing a model for studying the construction of transparency in interactions between governments and stakeholders. Building on theories about complex decision making, a heuristic model is developed that consists of a strategic, a cognitive, and an institutional perspective. To test the model's value, it is applied to two empirical cases: Dutch schools and the Council of the European Union. Applying the model to the school case provides insights into the connection between the introduction of transparency and the transformation in arrangements for safeguarding school quality. The case of the Council of the European Union highlights the role of transparency in the transformation of the council from a supranational to an intergovernmental body. The article concludes that the heuristic model, together with in‐depth, longitudinal case studies, helps us understand government transparency in relation to broader transformations in the public sector.  相似文献

We present a new tool for the estimation of the age of bloodstains, which could probably be used during forensic casework. For this, we used atomic force microscopy (AFM) for high-resolution imaging of erythrocytes in a blood sample and the detection of elasticity changes on a nanometer scale. For the analytic procedure we applied a fresh blood spot on a glass slide and started the AFM detection after drying of the blood drop. In a first step, an overview image was generated showing the presence of several red blood cells, which could easily be detected due to their typical "doughnut-like" appearance. The consecutively morphological investigations in a timeframe of 4 weeks could not show any alterations. Secondly, AFM was used to test the elasticity by recording force-distance curves. The measurements were performed immediately after drying, 1.5 h, 30 h and 31 days. The conditions were kept constant at room temperature (20 degrees C) and a humidity of 30%. The obtained elasticity parameters were plotted against a timeline and repeated several times. The elasticity pattern showed a decrease over time, which are most probably influenced by the alteration of the blood spot during the drying and coagulation process. The preliminary data demonstrates the capacity of this method to use it for development of calibration curves, which can be used for estimation of bloodstain ages during forensic investigations.  相似文献

Recent challenges have brought the discipline of firearms and tool mark identification to the forefront in recent court cases. This article reviews those challenges and offers substantial support for the scientific foundations of the firearms and tool mark identification discipline. A careful review of the available literature has revealed that firearms and tool mark identification is rooted in firm scientific foundations, critically studied according to the precepts of the scientific method culminating in the Association of Firearms and Toolmark Examiners' Theory of Identification. Firearms and tool mark identification has been validated in a manner appropriate for evidence of the kind to be expected in firearms and tool mark examinations. Proficiency tests and error rates have been studied and can provide consumers of the disciple with a useful guide as to the frequency with which misidentifications are reported in the community using appropriate methodologies and controls. As a result, the primary issues in recent challenges do not invalidate the firearms and tool mark discipline as a science nor should it detract it from its admissibility in a court of law.  相似文献

Technology development and democratization have been identified as the general drivers of the worldwide thrust in transparency. But what transparency regimes do these drivers generate in different countries? This mixed method study indicates that national regimes are different due to pre-existing institutional differences and critical junctures in the historical development of transparency regimes. Our analysis shows that the U.S. transparency regime can be characterized as a rules-based approach while a principles-based transparency regime prevails in the Netherlands. This article nuances the debate about the global character of transparency and highlights two different outcomes of the push for transparency.  相似文献

To what extent do people become less trusting of the government under threatening policy contexts? The authors find evidence that Secure Communities, a bureaucratic program that enhances immigrant policing through collaboration between local law and immigration enforcement agencies, spurs mistrust among Latinos but not non‐Latinos. This article focuses on the politics of immigration and health, two issue areas marked by large‐scale bureaucratic developments over the last 50 years. The authors argue that a major consequence of expanding immigrant policing is its trickle‐down effect on how individuals view public institutions charged with the provision of public goods, such as health information. The results indicate that Latinos in locales where immigrant policing is most intense express lower levels of trust in government as a source of health information. Through a policy feedback lens, the findings suggest that the state's deployment of immigrant policing conveys more widespread lessons about the trustworthiness of government .  相似文献
