Professional work is often regulated by procedures that shape the information seeking involved in performing a task. Yet, research on professionals’ information seeking tends to bypass procedures and depict information seeking as an informal activity. In this study we analyze two healthcare tasks governed by procedures: triage and timeouts. While information seeking is central to both procedures, we find that the coordinating nurses rarely engage in information seeking when they triage patients. Inversely, the physicians value convening for timeouts to seek information. To explain these findings we distinguish between junior and expert professionals and between uncertain and equivocal tasks. The triage procedure specifies which information to retrieve but expert professionals such as the coordinating nurses tend to perform triage, which is an uncertain task, by holistic pattern recognition rather than information seeking. For timeouts, which target an equivocal task, the procedure facilitates information seeking by creating a space for open-ended collaborative reflection. Both junior and expert physicians temporarily suspend patient treatment in favor of this opportunity to reflect on their actions, though partly for different reasons. We discuss implications for models of professionals’ information seeking. 相似文献

It has long been recognised that analogies may be a useful tool in science education. At the same time, it has been found that there are challenges to using analogies in teaching. For example, students might not identify a suitable analogy, might not recognise how the taught target domain is similar to the source domain to which it is compared, or may fail to realise where the analogy breaks down. The present study offers a review of two trends which reflect the ambition to come to terms with such challenges: self-generated analogies, making use of students’ own analogies in teaching, and analogy generation in collaborative settings, such as in small-group work. Empirical studies show predominately positive results with regard to students’ enjoyment and learning gains, and point to opportunities for formative assessment. The specificities of language in conjunction with analogy and the role of analogies in authentic science classroom discourse are suggested as areas of study that deserve more attention going forward. 相似文献

This paper reports a longitudinal multi-case research project encompassing 38 semi-structured interviews conducted in 2011 and 2012 with four students, 12 researchers and 22 companies relating to a total of 25 university–industry collaborations. The interviews covered the collaboration type, the initiation of the collaboration and details concerning the planning of the collaboration. In addition, the interviews focused on the relationships between the people involved in the collaboration and the effects of project management. We distinguish between project management success and project success, and identify potential good practice. The paper concludes that, whereas project management success was not found to be causally related to project success, there seems to be a clearer link between project management success and ensuring effective use of resources in both companies and universities. There is also evidence that it is problematic when corporate managers think they can run research projects like lean production companies. 相似文献

Social network analysis (SNA) has been used in many educational studies in the past decade, but what these studies have in common is that the populations in question in most cases are defined and known to the researchers studying the networks. Snowball sampling is an SNA methodology most often used to study hidden populations, for example, groups of homosexual people, drug users or people with sexually transmitted diseases. By use of a snowball sampling approach, this study mapped municipal social networks of educational actors, who were otherwise hidden to the researchers. Subsequently, the resulting networks were validated through interviews with central respondents and by using prior investigations of the municipalities. Our results confirmed that the majority of the designated respondents recognized the resulting sociograms and their own position in these. It was also found that not all predictions based on existing knowledge of the municipalities aligned with SNA data. However, these discrepancies could be explained by development in the municipalities in the time following previous investigations. This study shows that snowball sampling is an applicable method to use for mapping hidden populations in educational settings, but also that qualitative studies are needed in order to interpret the networks in real-life contexts. 相似文献

In addition to increasing cognitive skills and preparing students for the labour market, one of the core tasks of education is to prepare citizens for participation in democracy. Considering the ideal of democratic equality, it is important to know the degree to which civic outcomes of education are distributed equally. One feature of the education system that can lead to differential civic outcomes is tracking, that is, the sorting of students into different types of education. In this study, we examine the relationship between type of education (general/academic or vocational) and five attitudinal dimensions of civic and political engagement between the ages of 14 and 49 years in the Netherlands. By using panel data from the Netherlands Longitudinal Lifecourse Study (n = 5,312) and applying linear fixed effects models, we can observe the effect of a transition in the type of education on the within-person change in our outcome variables. The findings demonstrate that transitions in the type of education have little effect on intention to vote, trust in institutions or ethnic tolerance. However, students making transitions in general/academic education develop higher levels of interest in politics and generalised trust than do students in vocational education or people outside the education system. This point suggests that general/academic education fosters civic and political participation. 相似文献

This paper presents an empirical analysis of two different methodologies for calculating national citation indicators: whole counts and fractionalised counts. The aim of our study is to investigate the effect on relative citation indicators when citations to documents are fractionalised among the authoring countries. We have performed two analyses: a time series analysis of one country and a cross-sectional analysis of 23 countries. The results show that all countries’ relative citation indicators are lower when fractionalised counting is used. Further, the difference between whole and fractionalised counts is generally greatest for the countries with the highest proportion of internationally co-authored articles. In our view there are strong arguments in favour of using fractionalised counts to calculate relative citation indexes at the national level, rather than using whole counts, which is the most common practice today. 相似文献

This paper examines and discusses the views on science and society held among PhD students working in two different industrially and environmentally driven research programmes in the broad area of green chemistry. It is based on thirteen in-depth interviews. The analysis shows three main ways of handling the situation as “post-academic” PhD student: (1) the student sees the PhD work mainly as a job and does not reflect about his/her research or the research funding, (2) the student is satisfied with the post-academic situation, accepts the established innovation policy discourse and is sceptical to traditional academic research, and (3) the student sees collaborative research programmes as a way to get funding, which can be used for secretly done basic research. Most PhD students either emphasise usefulness—in line with the dominating research policy discourse—or they adopt the positivistic view of science as objective and independent of the surrounding society. However, there are only a few signs of “double problematisation”, that is a critical view where both disciplinary-oriented and industry-dependent research are problematised. 相似文献

AbstractHip adduction strength is important for kicking and acceleration in soccer players. Changes in hip adduction strength may therefore have an effect on soccer players’ athletic performance. The purpose of this study was to investigate the acute and sub-acute effects of a kicking drill session on hip strength, concerning isometric hip adduction, abduction and flexion torque of the kicking leg and the supporting leg. Ten injury-free male elite soccer players, mean ± s age of 15.8 ± 0.4 years participated. All players underwent a specific 20 min kicking drill session, comprising 45 kicks. The players were tested the day before, 15 min after and 24 h after the kicking drill session by a blinded tester using a reliable test procedure. The isometric hip-action and leg-order were randomized. For the kicking leg, hip adduction torque increased from 2.45 (2.19–2.65) Nm ? kg?1, median (25th–75th percentiles), at pre-kicking to 2.65 (2.55–2.81) Nm ? kg?1 (P = 0.024) 24 h post-kicking. This may have implications for the soccer player’s ability to maximally activate the hip adductors during kicking and acceleration, and thereby improve performance the day after a kicking drill session. 相似文献

This paper discusses methods for benchmarking vocational education and training colleges and presents results from a number of models. It is conceptually difficult to benchmark vocational colleges. The colleges typically offer a wide range of course programmes, and the students come from different socioeconomic backgrounds. We solve the comparability problem by focusing on effects in terms of retention and employment rates as opposed to the intermediate outcomes like grades. We neutralize cost differences using alternative cost measures. And we use detailed register data to account for student backgrounds. From a methodological point of view, we combine average methods (multilevel analysis) with frontier methods. We thus combine the key methods of school effectiveness research and school efficiency and productivity research. The analyses show that the efficiency of Danish vocational colleges varies considerably. Adopting best practices could lead to cost savings of between 9 and 33%. 相似文献
