This paper studies the role of geographic proximity for interaction on R&D, by exploring the special case of formalised university–industry interaction in the engineering sector. While numerous studies find that geographic proximity facilitates spillover effects between university and industry by utilising evidence from e.g. patenting and publishing activities, the geographical dimension is largely understudied in studies that report evidence from direct interaction. A series of interviews with R&D managers suggests that linkages in geographical proximity are more likely than distant linkages to generate impulses to innovation and create significant learning effects at the firm. Similarly, geographic proximate interaction is more likely to successfully contribute to R&D projects with short time to market. For long-term R&D projects, geographic proximity is generally seen as a less critical factor. A survey to 425 R&D managers in Swedish engineering firms provides evidence that supports these hypotheses. 相似文献

This paper discusses trends in contemporary Danish early childhood education and care (ECEC). Data are sourced from various policy documents, along with material from ongoing research projects in which the authors are involved. It is claimed that contemporary policy on Danish day care services has a tendency to emphasize narrow curriculum improvements and standardized testing. The democratic dimensions are still relatively strong, but at the moment these dimensions are interpreted within a skills‐and‐testing framework, which is leading to a situation where the political masquerades as the technical. 相似文献

This article presents the design and evaluation of a tool for inspecting conceptual models of system behaviour. The basis
for this research is the Garp framework for qualitative simulation. This framework includes modelling primitives, such as entities, quantities and causal
dependencies, which are combined into model fragments and scenarios. Given a library of model fragments and a scenario describing
an initial situation, the qualitative simulation engine generates predictions in the form of a state–transition graph. This
rich knowledge representation has potential for educational purposes. However, communicating the contents of simulation models
effectively to learners is not trivial. The predicate logic format used by Garp is not easy for non-experts to understand, and a simulation often contains so much information that it is difficult to get
an overview while still having access to detailed information. To address these problems, a tool has been developed that generates
graphical representations of the information contained in a qualitative simulation. This tool, named VisiGarp, incorporates a vocabulary of graphical elements for model ingredients and relationships, and combines these into interactive
diagrams. VisiGarp has been evaluated by thirty students, with promising results, using a setup which included simulation results and exercises
about Brazilian Cerrado ecology. 相似文献

How personality traits relate to structural brain changes in development is an important but understudied question. In this study, cortical thickness (CT) and surface area (SA), estimated using magnetic resonance imaging (MRI), were investigated in 99 participants aged 8–19 years. Follow‐up MRI data were collected after on average 2.6 years for 74 individuals. The Big Five personality traits were related to longitudinal regional CT or SA development, but limited cross‐sectional relations were observed. Conscientiousness, emotional stability, and imagination were associated with more age‐expected cortical thinning over time. The results suggest that the substantial individual variability observed in personality traits may partly be explained by cortical maturation across adolescence, implying a developmental origin for personality–brain relations observed in adults. 相似文献

Research on women’s football is still, especially in Asia, scarce. The purpose of this research has been to investigate the underlying points of attachment of women’s football spectators and how these influence future behaviour. The points of attachment scale – drawing on social identity theory – developed previously has been modified for the research setting to detect whether they are general determinants or country-specific indicators. Research was conducted in two countries, namely Japan and Germany. Surveys were conducted at two friendlies of the national team in each country (Japan: n = 607; Germany: n = 597). Attachment with the team, coach and women’s sport were defining overall attachment best. Intention to attend matches of the national team was significantly predicted by football attachment and previously attended games, while intention to attend matches of the league was significantly predicted by attachment with the coach and attended league games in the past. 相似文献

While much research has been done to analyze whether socioeconomic status influences prosocial behavior in the form of donations, no consensus has yet emerged in the relevant literature. We contribute to this research by studying, based on a dataset from a questionnaire of volunteers of sports clubs in Palatinate (part of Rhineland–Palatinate, Germany) whether social status affects donations. We measured social status of volunteers of sports clubs along the dimensions income, vocation, education and we considered status crystallization. Results showed that social status has a positive effect on the likelihood of donations. We report similarities and differences across different categories of donations (donations to one’s own sports club, to other clubs, to aid projects, and political parties). 相似文献

This paper surveys the prevalence and correlates of anabolic androgenic steroids (AAS) use among Norwegian adolescents, and examines the degree to which sports participation is a mediating or moderating factor to well-known correlations between AAS use and problem behaviour. The data come from the “Ungdata” study, a cross-national youth survey system offered to all municipalities in Norway (response rate: 74%, N?=?77,572). The study demonstrates a lifetime prevalence of AAS use of 1.27% and a higher prevalence among boys (1.81%) than girls (0.76%). The analyses show that AAS use is clearly related to problem behaviour such as violence and other substance use. When controlling for problem behaviour, there are no correlations between AAS use and exercising in a sports club or on one’s own, whilst there is a weak positive correlation between AAS use and exercising in a gym or engaging in other forms of physical exercise such as dancing or martial arts. These patterns are more or less the same for boys and for girls. We conclude that adolescent AAS use is a low-prevalence phenomenon that primarily takes place in smaller subgroups of individuals who engage in other forms of problem behaviour as well. 相似文献

The kinesiology concept is used worldwide and by many different professional groups with scientific aspirations. Yet nobody seems to know much about where it comes from and why it came into existence. This article traces the origins of the concept back to one of Sweden's greatest cultural exports of the nineteenth century – Swedish gymnastics – and the efforts of especially Swedish physiotherapists and physical educators to spread its scientific doctrines throughout the world. Primarily their goal was to convert the representatives of conventional medicine (pharmacology) into a more mechanical mode of understanding and curing illness (physiotherapy). While following in the footsteps of one physiotherapist/physical educator –‘the father of kinesiology’– and examining the ideological and historical conditions his so-called ‘mission’ was ruled by, the social construction of knowledge and science is made visible in a way seldom highlighted in the history of medicine and physical education. 相似文献
