This paper analyzes the effects of German labor market reforms on the competitiveness and performance of the German economy. The contribution starts with giving some background information on the rationale behind the reforms and stresses the specific structure of the German economy. We then describe the salient effects of the reforms for employment and labor market integration. Finally, the dark side of the reforms, i.e., labor market segmentation and wage inequality, are addressed, which leads to the general question of how the reforms can be reconciled with the notion of social justice. 相似文献

Zusammenfassung Dieser Beitrag gibt einen überblick über unterschiedliche Bildgebungs- und Bildverarbeitungsverfahren,
die heute in den Kliniken verwendet werden. Es wird die gesamte Bildkette von der Bildverarbeitung über
die Bildverbesserung bis hin zur Rekonstruktion und Bildregistrierung beschrieben. Die einzelnen Themenkomplexe
werden dabei aus medizinischer und technischer Sicht diskutiert. Aus den klinischen Anforderungen und den
gesetzlichen Randbedingungen folgen wichtige Grunds?tze für die Architekturkonzepte und den Entwicklungsprozess
medizinischer Bildverarbeitungssysteme.

There are many established reading strategy training programmes, which explicitly teach strategic and meta‐cognitive knowledge to improve reading comprehension. Although instruction in strategy knowledge leads to improvements in meta‐cognitive skills, the effects do not always transfer to reading comprehension. Therefore, to investigate preconditions for knowledge transfer, two different strategy training programmes were implemented in nine classes of Grade 6 students (N = 148) over the course of one school year. One programme involved teacher‐directed instruction of declarative meta‐cognitive knowledge (Reading Detectives; Rühl & Souvignier, 2006). The other aimed at improving executive meta‐cognition by guided practice: students worked with a computer program based on latent semantic analysis (LSA) (conText) and received immediate feedback on written summaries. Although both groups improved their strategy knowledge to the same extent, the conText group showed a greater improvement in reading comprehension. These fndings suggest that guided practice, which is characterised by intensive practice and individualised corrective feedback, is superior to explicitly teaching strategy knowledge. 相似文献

When trying to attain the benefits of open source software (OSS), proprietary closed source software (PCSS) firms are struggling to adopt this radically different practice of software development. We approach these adoption challenges as a problem of gaining support for organizational innovation. Through a mixed-method research design consisting of qualitative interviews and a survey of employees of a large telecommunications firm, we find that the organizational innovation to commercially engage in OSS has different impacts on technical and administrative dimensions of different job roles. Accordingly, individuals enacting different job roles are—on average—more or less well aligned with the OSS practice and OSS processes per se. We find that individual-level attributes can counterbalance the job role changes that weaken support for adopting OSS, while perceived organizational commitment has no effect. Suggestions for PCSS firms are presented and implications for innovation literature are discussed. 相似文献

Recent theory and research suggest that perfectionism is a personal factor contributing to athletes’ vulnerability to doping (using banned substances/drugs to enhance sporting performance). So far, however, no study has examined what aspects of perfectionism suggest a vulnerability in junior athletes. Employing a cross-sectional design, this study examined perfectionism and attitudes towards doping in 129 male junior athletes (mean age 17.3 years) differentiating four aspects of perfectionism: perfectionistic strivings, perfectionistic concerns, parental pressure to be perfect, and coach pressure to be perfect. In the bivariate correlations, only parental pressure showed a positive relationship with positive doping attitudes. In a multiple regression analysis controlling for the overlap between the four aspects, perfectionistic strivings additionally showed a negative relationship. Moreover, a structural equation model examining the relationships between all variables suggested that coach pressure had a negative indirect effect on attitudes towards doping via perfectionistic strivings. The findings indicate that perceived parental pressure to be perfect may be a factor contributing to junior athletes’ vulnerability to doping, whereas perfectionistic strivings may be a protective factor. 相似文献

Although chemistry is by far the largest scientific discipline according to any quantitative measure, it had, until recently, been virtually ignored by professional philosophers of science. They left both a vacuum and a one-sided picture of science tailored to physics. Since the early 1990s, the situation has changed drastically, such that philosophy of chemistry is now one of the most flourishing fields in the philosophy of science, like the philosophy of biology that emerged in the 1970s. This article narrates the development and provides a survey of the main topics and trends. 相似文献
