The industrial dynamics of Open Innovation—Evidence from the transformation of consumer electronics     

Jens Frslev Christensen  Michael Holm Olesen andJonas Sorth Kjr 《Research Policy》2005,34(10):1533-1549

This paper addresses how the Open Innovation concept, as recently coined by Henry Chesbrough, can be analyzed from an industrial dynamics perspective. The main proposition of the paper is that the specific modes in which different companies manage Open Innovation in regard to an emerging technology reflect their differential position within the innovation system in question, the nature and stage of maturity of the technological regime, and the particular value proposition pursued by companies. The proposition is analyzed through an in-depth study of the current transformation of sound amplification from linear solid state technology to switched or digital technology within the consumer electronics system of innovation. The analysis especially addresses the complex interplay between technology entrepreneurs and incumbents, and demonstrates that Open Innovation sometimes has to be conducted under conditions of high transaction costs.  相似文献

Perceived discomfort in running: scale development and theoretical considerations.     

G Tenenbaum  G Fogarty  E Stewart  N Calcagnini  B Kirker  G Thorne  S Christensen 《Journal of sports sciences》1999,17(3):183-196

The aim of this study was to develop a discomfort questionnaire to elicit the feelings and thoughts of people engaged in running activities. Ten runners who completed a particularly demanding 9-km run were asked to express their feelings and thoughts during the run they had just completed. These responses were recorded and later used as the first pool of items (k = 36). The questionnaire was then given to 171 runners in different distance races throughout the 1995 competitive season. These responses were analysed using exploratory factor analytic techniques and Rasch probabilistic analysis, as well as traditional reliability and validity procedures. The final version of the questionnaire consisted of 32 items divided into eight correlated subscales: proprioceptive symptoms, leg symptoms, respiratory difficulties, disorientation, dryness and heat, task completion thoughts, mental toughness, and head or stomach symptoms. These eight categories can be collapsed into three global categories suggested by researchers of pain: sensory-discriminative, motivational-affective and cognitive-evaluative. Rasch analysis suggested that the motivational-affective and cognitive-evaluative dimensions (i.e. the psychological) are the most experienced (i.e. rated highest). The eight subscales have ecological validity and were found to alter with the demands of different running distances.  相似文献   

Measuring Teacher Attitudes Toward Instructional Technology: A Confirmatory Factor Analysis of the TAC and TAT     

Dominick Shattuck  Kristen A. Corbell  Jason W. Osbourne  Gerald Knezek  Rhonda Christensen  Lisa Leonor Grable 《学校用计算机》2013,30(4):291-315

In this article the authors present a confirmatory factor analysis of the Teachers’ Attitudes Toward Computers (TAC) and the Teachers’ Attitudes Toward Information Technology (TAT) scales by Christensen and Knezek (1996, 1998) using large samples from three states. The TAC was reduced from 98 items and nine factors to 35 items and eight factors, while maintaining superior psychometric properties. The TAT was reduced from 50 items and five factors to 20 items measuring five factors, similarly maintaining excellent psychometric properties. The authors also developed a combined short form of both instruments using 42 items to measure 11 factors for use in situations where parsimony is critical.  相似文献

Genealogy and educational research     

Gerd Christensen 《International journal of qualitative studies in education》2016,29(6):763-776

The aim of this paper was to demonstrate how genealogy can be used as a method for critical education research. As Foucault emphasized, genealogy is a method for identifying the way in which the individuals are subjectified through discourse. The genealogical analysis in the article defines two mayor tendencies in contemporary Danish pedagogy: individualization and structuralizing. The analyses also show an example of how the two tendencies are intermingled in the Danish law of learning plans in day care institutions.  相似文献   

Risk and school science education     

Clare Christensen 《Studies in Science Education》2013,49(2):205-223

In this paper I consider a role for risk understanding in school science education. Grounds for this role are described in terms of current sociological analyses of the contemporary world as a ‘risk society’ and recent public understanding of science studies where science and risk are concerns commonly linked within the wider community. These concerns connect with support amongst many science educators for the goal of science education for citizenship. From this perspective scientific literacy for decision making on contemporary socioscientific issues is central. I argue that in such decision making, risk understanding has an important role to play. I examine some of the challenges its inclusion in school science presents to science teachers, review previous writing about risk in the science education literature and consider how knowledge about risk might be addressed in school science. I also outline the varying conceptions of risk and suggest some future research directions that would support the inclusion of risk in classroom discussions of socioscientific issues.  相似文献   

Getting Buzzed In the Library: The Use of Restaurant-Style Pagers for Reserves Checkout in an Academic Library     

Kymberly Goodson  Marlayna Christensen  Sarah Elliott  Abigail Lowery 《Journal of Interlibrary Loan, Document Delivery & Electronic Reserve》2013,23(2):117-129

In 2004, the Social Sciences and Humanities Library at the University of California–San Diego implemented restaurant-style pagers to notify waiting patrons that the reserve collection materials they needed were available. The authors describe the university libraries’ process for implementing the pagers and the success staff has had with pagers over the past four years, list other libraries that use pagers, suggest other library uses for pagers, and offer guidance to institutions that might consider this service enhancement.  相似文献   

Multitasking With Television Among Adolescents     

Claire G. Christensen  David Bickham  Craig S. Ross  Michael Rich 《广播与电子媒介杂志》2015,59(1):130-148

Using Ecological Momentary Assessment, we explored predictors of adolescents' television (TV) multitasking behaviors. We investigated whether demographic characteristics (age, gender, race/ethnicity, and maternal education) predict adolescents' likelihood of multitasking with TV. We also explored whether characteristics of the TV-multitasking moment (affect, TV genre, attention to people, and media multitasking) predict adolescents' likelihood of paying primary versus secondary attention to TV. Demographic characteristics do not predict TV multitasking. In TV-multitasking moments, primary attention to TV was more likely if adolescents experienced negative affect, watched a drama, or attended to people; it was less likely if they used computers or video games.  相似文献
