In Germany, different types of university-level institutions are available for tertiary education: traditional universities (Universit?ten) and??since the 1970s??universities of applied science (Fachhochschulen) as well as universities of cooperative education (Berufsakademien). The present study investigates differences in key areas related to students?? academic choices and success: do students at different types of university differ significantly in terms of cognitive performance, personality or social background? We compared N?=?1.230 students at traditional universities, universities of applied science, and universities of cooperative education (Baden-W??rttemberg Cooperative State University) on the basis of a large scale longitudinal study in the German federal state of Baden-W??rttemberg. Students of the different university types differed significantly in all three key areas (cognitive performance, personality, and social background) within the fields of technical sciences and economics. We determine the relative importance of these key areas for differences between university types and we discuss the implications of our findings.  相似文献   

Changing Funding Arrangements and the Production of Scientific Knowledge: Introduction to the Special Issue     

Jochen Gläser  Kathia Serrano Velarde 《Minerva》2018,56(1):1-10

With this special issue, we would like to promote research on changes in the funding of the sciences, social sciences, and humanities. Since funding secures the livelihood of researchers and the means to do research, it is an indispensable condition for almost all research; as funding arrangements are undergoing dramatic changes, we think it timely to renew the science studies community’s efforts to understand the funding of research. Changes in the governance of science have garnered considerable attention from science studies and higher education research; however, the impact of these changes on the conduct and content of research has not received sufficient attention, and theoretical insights into the connections between funding practices and research practices are few and far between. The aim of this special issue is to contribute to our theoretical understanding of the changing nature of research funding and its impact on the production of scientific knowledge. More specifically, we are interested in the interplay between funding and research practices: What is the impact of institutionalised funding arrangements on the production of scientific knowledge?  相似文献   

Preparing university teachers in The Netherlands: Issues and trends     

Fried Keesen  Theo Wubbels  Jan van Tartwijk 《International Journal for Academic Development》2013,18(2):8-16

Abstract

During the last ten years universities in The Netherlands have become less dependent on national policies regarding salary structures, promotion criteria and reward systems. At the same time the government has put increased pressure on universities to take a serious look at the quality of education in general, and at the teaching qualities of the staff in particular. The effects of these policies on staff development at Dutch universities is described. The main focus is on recent initiatives by two universities, Utrecht and Maastricht, to improve the preparation of university teachers. For Utrecht a closer look is taken at the career system, in which the importance of teaching competence is upgraded; at the teacher training programme; and at the role of portfolios and assessment in the programme. The implications are discussed.  相似文献   

Assessing Fit of Item Response Models Using the Information Matrix Test     

Jochen Ranger  Jörg‐Tobias Kuhn 《Journal of Educational Measurement》2012,49(3):247-268

The information matrix can equivalently be determined via the expectation of the Hessian matrix or the expectation of the outer product of the score vector. The identity of these two matrices, however, is only valid in case of a correctly specified model. Therefore, differences between the two versions of the observed information matrix indicate model misfit. The equality of both matrices can be tested with the so‐called information matrix test as a general test of misspecification. This test can be adapted to item response models in order to evaluate the fit of single items and the fit of the whole scale. The performance of different versions of the test is compared in a simulation study with existing tests of model fit, among them the test of Orlando and Thissen, the score test of local independence due to Glas and Suarez‐Falcon, and the limited information approach of Maydeu‐Olivares and Joe. In general, the different versions of the information matrix test adhere to the nominal Type I error rate and have high power for detecting misspecified item characteristic curves. Additionally, some versions of the test can be used in order to detect violations of the local independence assumption.  相似文献   

Bewegungstherapie in der Kinder- und Jugendlichenrehabilitation     

Dr. Jutta Ahnert  Stefan Löffler  Jochen Müller  Heiner Vogel 《Sportwissenschaft》2011,41(2):112-123

Although recommended in most treatment guidelines for child/adolescent rehabilitation, there is a lack of standards regarding the amount of exercise therapy that children and adolescents should receive during rehabilitation to ensure effective treatment. First, existing treatment guidelines were examined with regard to data on the frequency, duration, content, and modes of procedure of exercise therapy in the treatment of children and adolescents with asthma, obesity, and atopic dermatitis. Moreover, the actual implementation of exercise therapy in child/adolescent rehabilitative care was analyzed by using standardized data on the classification of therapeutic measures of the years 2007/2008 and comparing different rehabilitation centers. In the context of a nationwide survey, experts and clinicians were asked to describe and define how exercise therapy can be adopted in rehabilitative practice. On this basis, an expert workshop was conducted during which a pilot version of treatment guidelines for child/adolescent rehabilitation was developed and compared with actual medical care practice. Obese children/adolescents receive the highest amount of exercise therapy (4.7 h/week). However, children suffering from atopic dermatitis engage just as long in therapeutic exercises (1.9 h/week) as do children with asthma (1.9 h/week). Exercise therapy modules vary significantly between rehabilitation centers in terms of average frequency and duration. When comparing treatment guidelines and actual medical practice, it becomes apparent that only children up to the age of 7 with atopic dermatitis or asthma are provided to some degree adequately with exercise therapeutic treatment, whereas children aged 8 or older with asthma and/or obesity receive too little exercise therapy. Potential reasons for large variations between rehabilitation centers regarding the use of exercise therapy as well as possible factors that influence discrepancies between actual rehabilitative care practice and therapeutic guidelines are discussed.  相似文献   

Talking about public opinion and public opinion yet to come: Media and legislator constructions of public opinion in the Clinton‐Lewinsky Scandal     

Amy Fried  Timothy M. Cole 《The Communication Review》2013,16(2):219-251

Previous scholarship has argued that constructions of public opinion serve one of three dominant purposes: (1) to provide drama; (2) to promote particular strategic political interests; and (3) to symbolically legitimize the public's role in democracy. This paper analyzes media and legislator constructions of public opinion in the Clinton‐Lewinsky scandal. We assess the uses of public opinion and the purposes to which they were put, and particularly examine the use of different time frames in this discourse. Throughout the scandal, the public remained firmly ambivalent about President Clinton, with majorities supporting him remaining in office, even as they disapproved of his sexual relationship with Ms. Lewinsky. However, the media frequently emphasized the possibility that public might change, and this future orientation was joined to a strongly disapproving emphasis on public morality, rooted in a construction of past values. Later the media took present public opinion as a given, but political implications for the present and future framed the coverage. Once the scandal came to Congress, members of Congress usually recognized the public's support for President Clinton, but offered different interpretations of the roots of this support, its proper influence on Congress, and its future course. In assessing political consequences of their votes, legislators acted like investors involved in futures markets, and judged which opinions were likely to retain intensity in the coming months and years. Changing in a dynamic fashion in response to events, elites’ judgments, and polls, constructions of public opinion served multiple purposes, and were strongly tinged by assessments about the stability and basis of public opinion. The low use of present‐oriented time frames delegitimized citizen views.  相似文献

Prospective analysis of technological innovation systems: Identifying technological and organizational development options for biogas in Switzerland   总被引：1，自引：0，他引：1  

Jochen Markard  Martin Stadelmann  Bernhard Truffer 《Research Policy》2009,38(4):655-667

In this article, we put forward a concept for the identification and analysis of future development options of technological innovation systems. The key element of our approach, the so-called variation analysis, is a methodology to identify coherent socio-technical and organizational variants within a specific innovation field. Consistent combinations of these two dimensions may be interpreted as nuclei for alternative future developments of innovation systems. The method may be used in discursive foresight processes to inform strategy formulation of firms or policy makers who see a utility in furthering the innovation field. The paper has a focus on developing the theoretical background and the analytical structure of the methodology. Empirically, we illustrate the method for the innovation system of biomass digestion in Switzerland.  相似文献   

Reliability and validity of a soccer passing test using the Footbonaut     

Christian Saal  Jochen Zinner  Harald Fiedler  Ralf Lanwehr  Jürgen Krug 《Sportwissenschaft》2018,48(3):334-340

The aim of this study was to investigate the reliability and validity of a soccer short passing test using the Footbonaut training system. Forty-eight young skilled soccer players and 31 lesser-skilled soccer players completed a test and a retest, each involving four sessions a day of a Footbonaut short passing test (FSPT). We found significant differences in mean execution times for skilled (mean [M]?=?2487, standard deviation [SD] ?=?155) and lesser-skilled players (M?=?2682, SD?=?176) but no significant difference in accuracy (M?=?74.13, SD?=?7.65; M?=?72.19, SD?=?8.13) between groups. The results from linear mixed-effects models show that there were no significant effects of repeated measurements on execution time. In contrast, we found an estimated increase of 0.86% in accuracy per session for both groups. In conclusion, the FSPT offers a reliable and valid method to differentiate young soccer players at different competitive levels, using execution time.  相似文献
