Targets and Tools in Dutch Access Policies     

Frans Kaiser  Hans Vossensteyn 《Higher Education Quarterly》2005,59(3):187-204

In 2004 the Dutch Ministry of Education, Culture and Science set a concrete target: by 2010, close to 50% of the age cohort should participate in higher education, following the targets set in the UK and Sweden. However clear the target is set, the ways to achieve it are far less specified. In the article a number of possible instruments to achieve the target are discussed and their relevance in the Dutch context is analysed. It is concluded that there are a limited number of policy instruments available. However, given the devolution of access policy to the higher education institutions and the influence of broader societal trends on participation our expectations on what government can do to reach its target need to be modest.  相似文献

Beyond stacking in American football towards an understanding of cultural transmission,social identity and self-categorization     

Kent Kaiser  Dylan Williams  Dawn Norwood 《Sport in Society》2016,19(10):1573-1595

Relying on cultural transmission, social identity and self-categorization theories, this study uses an innovative two-part photo-pasting and survey method to investigate quantitatively and qualitatively non-fans’, fans’ and players’ assumptions about what positions black and white players should occupy in American football. Both white and black players and fans showed evidence of being cultural transmitters of racial ideologies associated with the quarterback position in American football. Overall, the respondent choices for quarterback diverged significantly from equality but not significantly from the reality of the National Football League. Players and fan and non-fan participants alike showed evidence of being cultural consumers and transmitters of racial ideologies associated with the quarterback position. Narrative reasons for player choices aligned with past literature about racial stereotypes. On most measures, the findings did not differ greatly among the institutions from which study participants were drawn, their diversity in geography, racial composition, ideology, athletic division and public–private status notwithstanding.  相似文献

Gleichstellung von Frauen und Männern an vollrechtsfähigen Universitäten     

Gabriele Kucsko-Stadlmayer 《Zeitschrift für Hochschulrecht, Hochschulmanagement und Hochschulpolitik: zfhr》2007,6(1):8-17

Trotz hoher Studentinnen- und Absolventinnenzahlen in den meisten Studienrichtungen ist der Anteil der Frauen an akademischen Spitzenpositionen noch immer gering. Die Gründe für dieses Missverhältnis liegen in einer Reihe spezifischer Schwierigkeiten, mit denen Frauen bei universitären Laufbahnen konfrontiert sind. Die Politik der Europäischen Union verfolgt seit 1999 das explizite Ziel, Frauen stärker in der universitären und außeruniversitären Forschung zu verankern. Mit dem Vertrag von Amsterdam wurde auch der gemeinschaftsrechtliche Rahmen neu gestaltet. Das UG 2002 hat "Frauenförderung" und "Gleichstellung von Frauen und Männern" zur Aufgabe der Universitäten und damit zu einem zentralen Teil ihres Bildungsauftrags erklärt. Die Europäische Strategie des "Gender Mainstreaming" wurde so in eine innerstaatliche, alle Universitätsorgane bindende Verpflichtung umgesetzt. Der Beitrag behandelt die rechtlichen Möglichkeiten der vollrechtsfähigen Universitäten zur Frauenförderung und bewertet Reichweite und Wirksamkeit der neuen Rechtslage.  相似文献   

Freelancers and the absorption of external knowledge: practical implications and theoretical contributions     

Arjan?KozicaEmail author  Ulrike?Bonss  Stephan?Kaiser 《知识管理研究与实践》2014,12(4):421-431

The term absorptive capacity (AC) describes the process of utilising external knowledge. Although firms are becoming increasingly reliant on highly skilled freelancers as a source of external knowledge, the literature on AC has not incorporated this collaboration for freelancers. In this paper, we address this research deficit in two ways: First, we argue that the ability to collaborate effectively and efficiently with freelancers plays a crucial role in the process of absorbing external knowledge. Second, we argue that the example of freelancers challenges researchers to rethink the conceptualisation of organisational boundaries within the concept of AC. Our paper is based upon previous theoretical insights and exploratory empirical data from a research project on German IT freelancers. For the practice of knowledge management, our paper elaborates upon how organisations can enhance their AC by investing in practices and routines that contribute to successful collaboration with freelancers.  相似文献   

Transport and separation of micron sized particles at isotachophoretic transition zones     

Gabriele Goet  Tobias Baier    Steffen Hardt 《Biomicrofluidics》2011,5(1)

Conventionally, isotachophoresis (ITP) is used for separation of ionic samples according to their electrophoretic mobilities. We demonstrate that the scope of ITP applications may be extended toward particle concentration and separation. Owing to the distributions of electrolyte concentration and electric field inside a transition zone between two electrolytes, a number of different forces act on a small particle. As far as possible, we provide estimates for the order of magnitude of these forces and analyze their scaling with the particle size and the electric-field strength. Furthermore, we experimentally demonstrate that polymer beads of 5 μm diameter dispersed in a high mobility “leading” electrolyte are picked up and carried along by an ITP transition zone which is formed with a low mobility “trailing” electrolyte. By studying the particle positions and trajectories, we show that impurities in the electrolytes play a significant role in the experiments. Additionally, it is experimentally shown that different types of beads can be separated at an ITP transition zone. In particular, beads of 1 μm diameter are not carried along with the transition zone, in contrast to the 5 μm beads. The presented technique thus adds to the portfolio of electrokinetic transport, concentration, and separation methods in microfluidics.  相似文献   

Von der Lehrerausbildung in den Beruf – Fachbezogenes Wissen als Voraussetzung für Wahrnehmung,Interpretation und Handeln im Unterricht     

Prof. Dr. Sigrid Blömeke  Prof. Dr. Johannes König  Dr. Andreas Busse  Dr. Ute Suhl  Jessica Benthien  Prof. Dr. Martina Döhrmann  Prof. Dr. Gabriele Kaiser 《Zeitschrift für Erziehungswissenschaft》2014,17(3):509-542

The transition from teacher training into the teaching profession is seen to be key in the biography of a teacher. Yet there is a lack of enquiry into the development of the content knowledge (CK) and pedagogical content knowledge (PCK) held by teachers at the end of their education, and into the significance of this knowledge for situational and behavioural cognition. On the basis of data from the international comparative study TEDS-M 2008 and the Germany-based 2012 follow-up, this contribution investigates the knowledge and skills development of teachers during the transition from teacher training to the teaching profession in a four-year longitudinal study with n = 171 mathematics teachers. Three test formats (paper-and-pencil, video-vignettes and speed tests) are used to examine various indicators for teacher expertise. In addition to the analysis of changes in mathematical CK and PCK levels, path analysis is used to determine the extent to which this knowledge functions as a predictor for the perception and interpretation of classroom situations, the decision-making in these situations, and the quick identification of student mistakes. The results show only small changes in the group mean (for MCK there is a small loss, whereas MPCK remains constant), but high fluctuation (i. e. weak correlation) in the MPCK ranking between the two measurement occasions, pointing to differential learning effects gained from teaching practice. There are also significant differences in predictability: MCK is important for the speed indicators of teacher expertise; MCK and MPCK for the perception and interpretation of situations, and for the generation of action strategies. These findings can on the one hand help to facilitate the evaluation of beginning teachers’ need for support and, on the other hand, they indicate the necessity for the early integration of practice-based elements into teacher training programmes with the aim of developing PCK and related skills.  相似文献   

Sorting on GPUs for large scale datasets: A thorough comparison     

Gabriele Capannini  Fabrizio SilvestriRanieri Baraglia 《Information processing & management》2012

Although sort has been extensively studied in many research works, it still remains a challenge in particular if we consider the implications of novel processor technologies such as manycores (i.e. GPUs, Cell/BE, multicore, etc.). In this paper, we compare different algorithms for sorting integers on stream multiprocessors and we discuss their viability on large datasets (such as those managed by search engines). In order to fully exploit the potentiality of the underlying architecture, we designed an optimized version of sorting network in the K-model, a novel computational model designed to consider all the important features of many-core architectures. According to K-model, our bitonic sorting network mapping improves the three main aspects of many-core architectures, i.e. the processors exploitation, and the on-chip/off-chip memory bandwidth utilization. Furthermore we are able to attain a space complexity of Θ(1). We experimentally compare our solution with state-of-the-art ones (namely, Quicksort and Radixsort) on GPUs. We also compute the complexity in the K-model for such algorithms. The conducted evaluation highlight that our bitonic sorting network is faster than Quicksort and slightly slower than radix, yet being an in-place solution it consumes less memory than both algorithms.  相似文献
