This paper surveys the current state of the art concerning the management and economic impact of geographically decentralized research and development (R&D) in multinational companies (MNCs). This line of research has recently begun to attract renewed interest, in reflection of not only critical new trends regarding the nature and conditions of technological change but also significant developments in the realm of economic and managerial theory.The aim of this paper is, first, to outline the empirical and theoretical background and perspective of this new research agenda. Second, it gives a summary and overview of prior research in the area. Third, it outlines the content and structure of a number of recent studies. Based on these studies the paper identifies a number of trends and implications in terms of policy issues and critical areas for future research. 相似文献

This article presents an investigation that was funded by the Swedish Institute into the role of creative practice in architectural research as evidenced in Swedish doctoral theses. The sample was mapped and analysed in terms of clusters of interest, approaches, cultures of knowledge and uses of creative practice. This allowed the identification of the ontological, epistemological and methodological attitudes of the researchers, and hence a glimpse of their implicit worldview. The authors claim that the relationship between worldview and research actions in emerging areas of research such as architecture is often under‐scrutinised, resulting in a disjunction between aims and strategies for action. Architectural research in which creative practices make an essential contribution to the aims, might represent something new in academic research. The investigators therefore focused on identifying cases in which creative practice was – or was claimed to be – integrated in an essential way into the research process. There were two principal conclusions. The first was that the mere presence of practice was not necessarily an indicator of so‐called arts‐based research. The second was that cases of arts‐based research that could be regarded as a new paradigm – as opposed to a variant of existing paradigms – are less common than is claimed by the researchers themselves. As a result, this article makes a contribution to the debate on whether so‐called practice‐based research should be regarded as a distinct new paradigm. 相似文献

This paper presents the first results from a longitudinal qualitative study following 38 Danish students' choice of higher education. By using a narrative psychological framework it is shown how the choice of higher education is embedded in various dilemmas, making it difficult for the students to make meaningful choices. They believe the choice should be unique and individual and that it should correspond with who they are and wish to become. However, the analysis shows that choosing what to study after upper-secondary school is a complex ongoing and social process, rather than an isolated individual event. Implications of these results are discussed and the educational system is urged to provide room for and facilitate students' production of choice narratives. 相似文献

Students' images of science and scientists are generally assumed to influence their related subject choices and aspirations for tertiary education within science and technology. Several research studies have shown that many young people hold rather stereotypical images of scientists, making it hard for them to see themselves as future scientists. Adolescents' educational choices are important aspects of their identity work, and recent theories link individual choice to the perceived match between self and prototypical persons associated with that choice. In the present study, we have investigated images of scientists among the segment of the upper secondary school students (20 % of the cohort) from which future Danish scientists are recruited. Their images were rather realistic, only including vague and predominantly positive stereotypical ideas. With a particular Science-and-Me (SAM) interview methodology, we inquired into the match between self- and prototypical-scientists (N?=?30). We found high perceived similarity within a core of epistemological characteristics, while dissimilarities typically related to a social domain. However, combining interview data with survey data, we found no significant statistical relation between prototype match and aspirations for tertiary education within science and technology. Importantly, the SAM dialogue revealed how students negotiate perceived differences, and we identified four negotiation patterns that all tend to reduce the impact of mismatches on educational aspirations. Our study raises questions about methodological issues concerning the traditional use of self-to-prototype matching as an explanatory model of educational choice. 相似文献

Why space matters in technological innovation systems—Mapping global knowledge dynamics of membrane bioreactor technology 总被引:1,自引:0,他引:1
Studies on technological innovation systems (TISs) often set spatial boundaries at the national level and treat supranational levels as a geographically undifferentiated and freely accessible global technological opportunity set. This article criticizes this conceptualization and proposes instead to analyze relevant actors, networks and processes in TIS from a relational perspective on space. It develops an analytical framework which allows investigating innovation processes (or ‘functions’) of a TIS at and across different spatial scales. Based on social network analysis of a co-publication dataset from membrane bioreactor technology, we illustrate how the spatial characteristics of collaborations in knowledge creation vary greatly over relatively short periods of time. This finding suggests that TIS studies should be more reflexive on system boundary setting both regarding the identification and analysis of core processes as well as in the formulation of policy advice. 相似文献

Abstract The associations between physical competence, self-perceived bodily competence, parental concern for their children's motor skill development, and teachers' evaluation of their bodily competence were assessed in 646 six- to seven-year-olds. Physical competence was assessed by the German motor ability test “Körperkoordinationstest für Kinder”, while the children's, their parents', and their teachers' evaluations were obtained through questionnaires. Parental concern, teacher evaluation, and a high body mass index were the strongest predictors of low physical competence (motor skill quotient <85). Teachers' evaluation of bodily competence was associated with low self-perceived bodily competence in the children even after adjustment for motor skill quotient, with an odds ratio of 2.3 (P < 0.05) between the lowest and highest of the three levels after correction for motor skill competence. Results indicate that teachers' evaluation of children's motor skills should be considered a key factor when tracking and assessing physical competencies among youth. 相似文献

Abstract Methods of analysis that include an assessment of opponent interactions are thought to provide a more valid means of team match performance. The purpose of this study was to examine the effect of playing tactics on achieving score-box possession by assessing opponent interactions in Norwegian elite soccer matches. We analysed a random series of 1703 team possessions from 163 of 182 (90%) matches played in the professional men's league during the 2004 season. Multidimensional qualitative data obtained from ten ordered categorical variables were used. Offensive tactics were more effective in producing score-box possessions when playing against an imbalanced defence (28.5%) than against a balanced defence (6.5%) (P < 0.001). Multiple logistic regression found that, for the main variable “team possession type”, counterattacks were more effective than elaborate attacks when playing against an imbalanced defence (odds ratio: 2.69; 95% confidence interval: 1.64 to 4.43) but not against a balanced defence (odds ratio: 1.14; 95% confidence interval: 0.47 to 2.76). Assessment of opponent interactions is critical to evaluate the effectiveness of offensive playing tactics on producing score-box possessions, and improves the validity of team match-performance analysis in soccer. 相似文献

AbstractThe aim of this study was to evaluate the physiological effects of soccer and Zumba among female hospital employees during a 40-week intervention period. Hospital employees (n = 118) were cluster-randomised to either a soccer group (n = 41), a Zumba group (n = 38) or a control group (n = 39). Both training groups were encouraged to perform 1-h training sessions twice a week outside working hours throughout the 40 weeks. Maximal oxygen uptake (VO2 max), blood pressure and body composition were measured and blood samples collected before and after the intervention period. Using intention-to-treat analyses, the Zumba group improved VO2 max compared to the control group (2.2 mL · kg?1 · min?1, 95% CI, 0.9, 3.5, P = 0.001), with no significant increase in the soccer group (1.1 mL · kg?1 · min?1, 95% CI, ?0.2, 2.4, P = 0.08). Both intervention groups reduced total body fat mass and fat percentage compared to the control group (P < 0.01). In the soccer group, but not the Zumba group, a significant difference in lower limb bone mineral density and bone mineral content was observed in comparison to the control group (P < 0.01). Furthermore, the soccer group, but not the Zumba group, had increased plasma osteocalcin (6.6 µg · L?1, 95% CI, 2.2, 11.0, P < 0.01) and decreased plasma leptin (?6.6 µg · L?1, 95% CI, ?12.5, ?0.7, P < 0.05) compared to the control group. The present study suggests that workplace-initiated soccer and Zumba training comprising 1–2 sessions per week outside working hours may promote physiological health among female hospital employees. 相似文献
