Wirkungen zentraler Abschlussprüfungen im Mehrebenensystem Schule. Eine Zwischenbilanz internationaler und nationaler Befunde und Forschungsdesiderata

Statewide exit exams have become a central governance instrument at the end of secondary schooling in Germany. In the article, the current state of research in Germany is systematized from an international comparative perspective in relation to intended and unintended effects. Findings regarding state exam policies and effects at the school and instructional level are presented as an interim report on a comparably young field of research. The findings show differences by states, subjects and courses which suggest that there is no general effect of statewide exams. In this context, future research should account for the heterogeneity of exam procedures to a greater degree.     

Elite und Exzellenz aus der Perspektive von Jugendlichen und ihren Peers an exklusiven Schulen

Against the backdrop of the recent political discourse on elite and excellence in the German education system, this paper examines how such constructions manifest themselves in programmatic concepts of schools and in the orientations of their pupils and their peers. They are reconstructed on the basis of a qualitative research project on educational careers of young people. This paper focuses on pupils and their peers at an elite school of sports and an international school. Firstly, the state of research on those types of school as well as on educational careers of their pupils will be presented. Secondly, the theoretical reference points and the methodological design of the study will be introduced. At the core of the paper is the analysis of the education related orientations of selected cases of young people and their peers: How do they position themselves towards elite and excellence in their individual and collective orientations and how is this relevant for processes of distinction and coherence building in the groups? In the resuming part of the paper, the results will be summarised and related to the state of research and the scientific discourse on elite and excellence.

Quality Audits as a Tool for Quality Improvement in Selected European Higher Education Libraries

From the beginning of the 1990s, different types of quality management and evaluation systems have become integrated into higher education institutes throughout Europe due to the creation of the European Higher Education Area (EHEA). This has meant that the university libraries have had to learn how to evaluate their services and improve their quality. Quality audits are one tool that can be used in quality management approaches to assess how well an organization is being managed. This paper describes and benchmarks the use of external and internal auditing in three European academic libraries, i.e. the Medical Library of the University Medical Center Hamburg-Eppendorf (Germany), the Universitat Autònoma de Barcelona Library (Spain) and the University of Eastern Finland Library (Finland). The results reveal the best practices of auditing in these institutions; and recommendations are provided for the further development of library auditing and ways to improve co-operation between libraries.

Vertical microbubble column–A photonic lab-on-chip for cultivation and online analysis of yeast cell cultures

This paper presents a vertically positioned microfluidic system made of poly(dimethylsiloxane) (PDMS) and glass, which can be applied as a microbubble column (μBC) for biotechnological screening in suspension. In this μBC, microbubbles are produced in a cultivation chamber through an integrated nozzle structure. Thus, homogeneous suspension of biomass is achieved in the cultivation chamber without requiring additional mixing elements. Moreover, blockage due to produced carbon dioxide by the microorganisms—a problem predominant in common, horizontally positioned microbioreactors (MBRs)—is avoided, as the gas bubbles are released by buoyancy at the upper part of the microsystem. The patterned PDMS layer is based on an optimized two-lithographic process. Since the naturally hydrophobic PDMS causes problems for the sufficient production of microbubbles, a method based on polyelectrolyte multilayers is applied in order to allow continuous hydrophilization of the already bonded PDMS-glass-system. The μBC comprises various microelements, including stabilization of temperature, control of continuous bubble formation, and two optical configurations for measurement of optical density with two different sensitivities. In addition, the simple and robust application and handling of the μBC is achieved via a custom-made modular plug-in adapter. To validate the scalability from laboratory scale to microscale, and thus to demonstrate the successful application of the μBC as a screening instrument, a batch cultivation of Saccharomyces cerevisiae is performed in the μBC and compared to shake flask cultivation. Monitoring of the biomass growth in the μBC with the integrated online analytics resulted in a specific growth rate of 0.32 h⁻¹, which is almost identical to the one achieved in the shake flask cultivation (0.31 h⁻¹). Therefore, the validity of the μBC as an alternative screening tool compared to other conventional laboratory scale systems in bioprocess development is proven. In addition, vertically positioned microbioreactors show high potential in comparison to conventional screening tools, since they allow for high density of integrated online analytics and therefore minimize time and cost for screening and guarantee improved control and analysis of cultivation parameters.
