Granularity of algorithmically constructed publication-level classifications of research publications: Identification of topics     

Peter Sjögårde  Per Ahlgren 《Journal of Informetrics》2018,12(1):133-152

The purpose of this study is to find a theoretically grounded, practically applicable and useful granularity level of an algorithmically constructed publication-level classification of research publications (ACPLC). The level addressed is the level of research topics. The methodology we propose uses synthesis papers and their reference articles to construct a baseline classification. A dataset of about 31 million publications, and their mutual citations relations, is used to obtain several ACPLCs of different granularity. Each ACPLC is compared to the baseline classification and the best performing ACPLC is identified. The results of two case studies show that the topics of the cases are closely associated with different classes of the identified ACPLC, and that these classes tend to treat only one topic. Further, the class size variation is moderate, and only a small proportion of the publications belong to very small classes. For these reasons, we conclude that the proposed methodology is suitable to determine the topic granularity level of an ACPLC and that the ACPLC identified by this methodology is useful for bibliometric analyses.  相似文献   

New Information Technologies in Special Education     

J⊘rgen Hansen 《Educational Media International》2013,50(2):68-86

Abstract

The aim of this study is to examine possible applications of new information technologies (NIT) in special education within different educational, socio‐economic and socio‐cultural contexts and, in particular, the possibilities of transference of these applications from the industrialised nations to the developing countries. The study also contains references to positive and negative results of the use of NIT in the special education of children, youth and adults.  相似文献   

Academic Workload and Working Time: Retrospective Perceptions Versus Time‐Series Data     

Svein Kyvik 《Higher Education Quarterly》2013,67(1):2-14

The purpose of this article is to examine the validity of perceptions by academic staff about their past and present workload and working hours. Retrospective assessments are compared with time‐series data. The data are drawn from four mail surveys among academic staff in Norwegian universities undertaken in the period 1982–2008. The findings show that many academic staff retrospectively perceive that expectations of their work and task performance have increased and hence that they now work longer hours. In contrast, when time‐ series data are used to measure changes in time use (on an aggregate level) no empirical evidence is found in support of this claim; instead, a slight decline in the average number of weekly working hours can be observed. Two possible reasons for this disparity are discussed. First, that heavier workloads do not necessarily imply that academic staff work longer hours. Second, that younger generations of academic staff may report fewer work hours than previous counterparts.  相似文献

Strategies for Achieving Gender Equality in Higher Education and Research in Norway     

Ann S⊘yland  Anne-Marit Skarsb⊘  Nina Amble  Lise Christensen  Anna Ølnes 《Higher Education in Europe》2000,25(2):147-153

The vision behind the work of the gender equality advisors in Norwegian universities and the Research Council of Norway is that of full equality between women and men in all areas and at all levels of the sector of higher education. The Network of Gender Equality Advisors in Higher Education and Research was formed in 1994. Both good and less good news can be reported on the work accomplished so far. A double strategy is applied to tackle gender inequality: mainstreaming and special commitment.  相似文献

Inducing chemotactic and haptotactic cues in microfluidic devices for three-dimensional in vitro assays     

O. Moreno-Arotzena  G. Mendoza  M. Cóndor  T. Rüberg  J. M. García-Aznar 《Biomicrofluidics》2014,8(6)

Microfluidic devices allow for the production of physiologically relevant cellular microenvironments by including biomimetic hydrogels and generating controlled chemical gradients. During transport, the biomolecules interact in distinct ways with the fibrillar networks: as purely diffusive factors in the soluble fluid or bound to the matrix proteins. These two main mechanisms may regulate distinct cell responses in order to guide their directional migration: caused by the substrate-bound chemoattractant gradient (haptotaxis) or by the gradient established within the soluble fluid (chemotaxis). In this work 3D diffusion experiments, in combination with ELISA assays, are performed using microfluidic platforms in order to quantify the distribution of PDGF-BB and TGF-β₁ across collagen and fibrin gels. Furthermore, to gain a deeper understanding of the fundamental processes, the experiments are reproduced by computer simulations based on a reaction-diffusion transport model. This model yields an accurate prediction of the experimental results, confirming that diffusion and binding phenomena are established within the microdevice.  相似文献   

“It wouldn't be the same without nature”—The value of nature according to Finnish upper secondary school students     

Pia Sjöblom  Lili-Ann Wolff 《The Journal of environmental education》2017,48(5):322-333

This article describes an interview study on Finnish upper secondary school students' values of nature. Even if the Finnish adolescents' interest in nature has decreased, most of the interviewees in this study regarded nature as worthy of maintenance. They valued nature for its material, aesthetic, and recreational values, as well as its diversity and future value, and because of their holistic view of nature. The nature values of the students were complex. Therefore, we suggest education that supports their value development through deliberation, authentic involvement, and outdoor activities.  相似文献   

Researchers as evaluators: tasks, tensions and politics     

Liv Langfeldt  Svein Kyvik 《Higher Education》2011,62(2):199-212

Researchers undertake a number of different research evaluation tasks, taking up a substantial part of their research time—estimated to about one work month per year for a professor. This paper addresses the various evaluator roles and tasks researchers take on, and the tensions they involve. How the research evaluator role may conflict with the researcher role and with societal expectations is discussed, as well as the intrinsic tensions in peer review; including expertise vs. impartiality, evaluators as neutral judges vs. exercise of power and influence, divergent peer assessments vs. the need for unanimous conclusions in peer panels, peer review vs. increase in quantitative indicators, and accountability to society vs. peer review as preserving the autonomy of science. The examination of these tensions provides insight in the political aspects of peer review, and a basis for discussing an agenda for future studies on the role of peer evaluators. Major future challenges for peer review concern how to meet demands for transparency and public accountability, and maintain academic autonomy.  相似文献
