The impact of electric overhead radiant heaters on the microclimate, air flows, transport and deposition of suspended particulate matter (SPM) was monitored between March 2004 and March 2005 in the historic churches of Saint Michael Archangel in Szalowa and Saint Catherine in Cracow (Poland). The measurements show that although irradiation at the floor level increases temperature and reduces relative humidity in the interior of the church, the effect out of the heated zone and for the surfaces sheltered from irradiation is very limited, i.e. their extent is comparable with natural fluctuations inherent to the local climate of the church. The radiant heaters proved to generate little convectional flow of the air. Therefore, the heating system was not found to increase the concentration of SPM indoors; in particular, no re-suspension of particles already present in the church was observed. This work has demonstrated that the overhead radiant heaters are capable of providing localised heat to the areas where people congregate without adversely affecting painted walls and the works of arts displayed in churches. Care, however, should be taken that sensitive works of art are not exposed to the direct infrared radiation.  相似文献

Ahead of the pack? Explaining the unequal distribution of scholarships in Germany     

Christina Haas  Herman Van De Werfhorst 《British Journal of Sociology of Education》2017,38(5):705-720

This article investigates to what extent scholarships are unequally distributed among students in Germany and how these inequalities can be explained. Following sociological theory, the article argues that elites seek qualitative ways of distinguishing themselves in a mass higher education system. Using student surveys, we demonstrate that class effects cannot merely be explained with reference to class differences in academic achievement but that higher classes have better access to scholarships independent of earlier school performance. Class differences were particularly persistent when the intermediate classes were compared with higher classes with more education. These findings illustrate that social classes have different strategies when it comes to participating in higher education and suggest that information about and access to scholarships is important in gaining a class advantage.  相似文献   

Assisting College Students With Athletic Disengagement     

Jeffrey S. Van Lone  Michael Siembor  Brian J. Mistler  David J. Mapstone 《Journal of College Student Psychotherapy》2017,31(2):132-154

This article examines college student disengagement from sports, presents a multidimensional concept of athletic identity, and introduces a new measure intended to assist college counselors in their work with disengaged athletes. The Multidimensional Athletic Identity and Engagement Scale (MAIES) is introduced (Cronbach alpha .98, with subscale alphas between .78 and .96), and the results of exploratory and confirmatory factor analyses and convergent and divergent validity with 250 college student participants are presented. Using case examples, the authors discuss how counselors may use the MAIES in their work with students. Limitations of the study and suggestions for future research are discussed.  相似文献   

Combining entrepreneurial and scientific performance in academia: towards a compounded and reciprocal Matthew-effect?   总被引：2，自引：0，他引：2  

Bart Van Looy  Marina Ranga  Julie Callaert  Edwin Zimmermann 《Research Policy》2004,33(3):425-441

The increase of entrepreneurial activity within academia has raised concerns that the research orientation of universities might become ‘contaminated’ by the application-oriented needs of industry. Empirical evidence on this concern is scarce and ambiguous. We examine whether entrepreneurial and scientific performance in academia can be reconciled. Our empirical findings (KU Leuven, Belgium) suggest that both activities do not hamper each other; engagement in entrepreneurial activities coincides with increased publication outputs, without affecting the nature of the publications involved. As resources increase, this interaction becomes more significant, pointing towards a Matthew-effect. We finally suggest that balancing both activities further depends on the institutional policies deployed.  相似文献   

Publication and patent behavior of academic researchers: Conflicting, reinforcing or merely co-existing?   总被引：1，自引：0，他引：1  

Bart Van Looy  Julie Callaert 《Research Policy》2006,35(4):596-608

Increasing entrepreneurial activity within academia has raised concerns that the number of publications added to the scientific commons might be reduced or that academic research would be directed exclusively towards the application-oriented needs of industry. In the case of academic inventions, the potential conflict between public- and private-oriented considerations seems most salient. In this contribution, we examine whether the publication behavior of academic inventors (at K.U. Leuven) differs from their colleagues (non-inventors) working within similar fields of research. Our analysis reveals that inventors publish significantly more. Moreover, no empirical evidence was found for the ‘skewing problem’. These findings not only suggest the co-existence of both activities; they may actually reinforce each other.  相似文献   

Teachers' Voices in the Context of Higher Education Reforms in Armenia     

Susanna Karakhanyan  Klaas van Veen  Th.C.M. Bergen 《European Journal of Education》2011,46(4):508-523

In this article, teachers' sense-making and reasoning about higher education reforms in a post Soviet country, namely Armenia, are examined using an analytical framework with six sensitising concepts: beliefs, emotions, attitudes, change knowledge, attributions and organisational culture. The results of semi-structured interviews with 12 Armenian higher education teachers showed that they mainly felt distrust towards reforms and that the implementation initiatives caused dissatisfaction, frustration and therefore distortion. At a deeper level, the teachers mostly felt excluded from the reform process and that their role was depreciated. One striking feature was the predominant causal attribution of teachers to external, unstable and uncontrollable factors which question the success of the reforms.  相似文献   

The influence of competences and support on school performance feedback use     

Jan Vanhoof  Jean Pierre Verhaeghe  Martin Valcke  Peter Van Petegem 《Educational studies》2011,37(2):141-154

Information‐rich environments are created to promote data use in schools for the purpose of self‐evaluation and quality assurance. However, providing feedback does not guarantee that schools will actually put it to use. One of the main stumbling blocks relates to the interpretation and diagnosis of the information. This study examines the relationship between data literacy competences, support given in interpreting the information, actual use of the feedback and potential school improvement effect. A randomised field experiment with 188 school principals from primary education was set up and a post‐test was used to investigate the effects of a support initiative. The results revealed that a minority of schools invested significantly in the interpretation and diagnosis of the school performance feedback (SPF), despite the fact that most of the respondents showed an interest in the SPF report. In addition, data competence support and the subsequent use of feedback were found to be limited.  相似文献
