Seit einiger Zeit setzen sich in der deutschen Hochschulpolitik und an den Hochschulen Reformen im Rahmen des New Public Managements durch, die zu mehr Selbststeuerung und Effizienzerhöhung führen sollen. Im vorliegenden Artikel wird ein Vergleich der Hochschulsteuerung der 16 Landeshochschulsysteme Deutschlands vorgenommen. Zunächst werden die derzeitigen hochschulischen Steuerungsinstrumente systematisiert und anschließend zwei Governance‐Modellen zugeordnet, dem bürokratisch‐oligarchischen und dem Management‐Modell. Eine Einordnung der 16 Landeshochschulsysteme auf Basis dieser Systematisierung zeigt für die meisten Bundesländer eine Dominanz jener Steuerungsinstrumente, die dem Management‐Modell zugeordnet werden. Gleichwohl bestehen zwischen den Bundesländern deutliche Unterschiede in den jeweiligen Steuerungssystemen. Trotz der allgemeinen Annäherung an das Management‐Modell sind auf der konkreten Umsetzungsebene Varianten in der Ausgestaltung festzustellen. Demzufolge verwundert es nicht, dass der Erfolg von Hochschulen nicht nachweisbar von der gesetzlichen Verankerung des Management‐Modells abhängt, was am Beispiel der Exzellenzinitiative illustriert wird.  相似文献

人体气味的证据价值及检验技术进展   总被引:1,自引:0,他引:1  
人体气味是具体人的一种生物信息,皮肤腺是人体气味产生之源。由遗传基因控制的人类白细胞抗原,经由免疫系统决定人体气味的特征。遗留于犯罪现场的人体气味具有相对稳定性,是与案件事实相关联的一种物证,具有一定的证据能力。警犬鉴别是辨识人体气味的主要技术手段。电子鼻、气相色谱质谱等化学分析仪器也可用于人体气味的检测分析。利用气相色谱质谱(GC/MS)对气味进行辨识具有嗅觉学的作用。警犬鉴别人体气味的结果与仪器分析的结果相互印证是检测分析人体气味证据技术的发展方向,也是人体气味证据走上法庭的关键技术。  相似文献

The credit rating agencies that dominated the ratings of mortgage‐backed securities were Moody's and Standard & Poor's. The two agencies rated some 4.3 trillion dollars of bonds as triple AAA, yet within a period of 18 months these same rating agencies downgraded these bonds to below investment grade. This paper seeks to show that the ratings agencies business model, the issuer pays approach, led to major conflicts of interest with both the ratings agencies unable to walk away from a rating. The evidence given by analysts to Congressional Inquiries confirms a cultural revolution within the rating agencies, with analysts feeling unable to question the quality of a rating. Analysts who were described as being awkward by issuers were removed from the rating process. In the meantime, the income for the rating agencies increased from 3 billion dollars to 6 billion dollars, with the CEOs of the rating agencies receiving incomes comparable to the incomes to the CEOs of investment banks.  相似文献

Non‐possessory secured transactions are key components of market economies. National and international legal reform projects have been advanced to further their use and broaden access to credit. Yet reforms appear to be limited by practical obstacles posed by national legal categories. This article shifts the focus from domestically defined categories to the operational rules that allow secured transactions to perform their economic function of managing credit risk. This shift leads to a reconsideration of the rules governing publicity and an examination of the policy issues underpinning the evolution of publicity. The article argues that international publicity standards, based on a registry system, could offer a new strategy for reforming secured transactions laws. The recently adopted UNCITRAL's Registry Guide is analysed and considered as a possible tool for reforming national secured transactions laws.  相似文献

This article examines an experiment in delivering services and programs in communities that were affected by the 2009 Victorian bushfires. Three not‐for‐profit agencies received funding to develop and deliver programs over a period of three years with the aim of achieving sustainability for the programs thus created. They were not constrained by the requirements of normal government funding, which is short term, subject to competitive tendering and targeted at specific programs and client groups. The nature of the funding allowed the three agencies to introduce innovative programs tailored to the needs of the community and with the aim of building community capacity. However the question of whether the programs are sustainable when existing funding runs out remains open.  相似文献

This article examines whether the relationship between unemployment and criminal offending depends on the type of crime analyzed. We rely on fixed‐effects regression models to assess the association between changes in unemployment status and changes in violent crime, property crime, and driving under the influence (DUI) over a 6‐year period. We also examine whether the type of unemployment benefit received moderates the link to criminal behavior. We find significantly positive effects of unemployment on property crime but not on other types of crime. Our estimates also suggest that unemployed young males commit less crime while participating in active labor market programs when compared with periods during which they receive standard unemployment benefits.  相似文献

Abstract: Radiographs and computed tomography (CT) images have been increasingly applied and accepted in forensic sciences. Along with radiographs and CT images, the frontal sinus is often used for the individual identification because of its unique and unchangeable characteristics. The purpose of this study is to define the usefulness of three‐dimensional (3‐D) images of the frontal sinus for identification. CT images from 119 Korean cadavers were built up for 3‐D reconstruction and surveyed with 15 measurements. The total volume of the sinus, some nonmetric characteristics, and the bilateral asymmetry index in men differed significantly from those in women (p < 0.05). The digit codes, six sections and 10‐digit number, were almost able to accurately identify individuals (98%). This study showed a statistical difference between the sexes and classified the fused and prominent middle sinuses for the first time. This proposed method for identification is more accurate than those used in other studies.  相似文献

Despite the vast transitional justice scholarship relating to prisoner release, amnesties and prosecutions when conflicts end, there is a significant gap in practice and academic literature regarding wrongful convictions. Uniquely amongst post‐conflict societies, Northern Ireland has a body for investigating miscarriages of justice, albeit one designed for ‘ordinary’ appeals. In the absence of a formal truth‐recovery process, criminal appeals are becoming a proxy for addressing the role of the state during ‘The Troubles,’ as well as remedying individual injustices. This article examines the approach of the Northern Ireland Court of Appeal during the conflict. It charts the developments in its decision‐making following the cease‐fires and the establishment of the Criminal Cases Review Commission. It concludes that the current system is unsatisfactory as it ignores the effects of the conflict on the appeal process and offers no insights into the role of the Court during the conflict. Alternative models are suggested.  相似文献

Currently, there is no standardized protocol for multi‐detector computed tomography (MDCT) measurement of juvenile remains. Using 33 juvenile clavicles, this paper investigates a protocol to allow MDCT measurements, comparable or supplemental with traditional osteometric measurements, to be acquired for application to previously published algorithms. The results illustrate that there is no significant difference between MDCT measurements and those taken by direct osteometric methods. By presenting such a protocol, this paper takes the first steps toward validation of the process of conversion from measurement of dry juvenile bone to MDCT compatibility and allows the forensic world to take a step forward in standardizing the way MDCT is used for forensic practice. This paper assesses the limitations and potential applications of this virtual approach and offers some suggestions for where further work might progress the conversion of these new approaches into legally admissible anthropological techniques of age estimation.  相似文献
