Defining knowledge translation activities using Gibbons and Nowotny's Mode I and II forms of knowledge production, health researcher (N = 240) characteristics are compared with their knowledge translation activities. Applied researchers (n = 168) engaged in more Mode II activity (p < .001), perceived their work as having more impact (p < .001), and reported higher levels of relational capital (p < .001) when compared to basic researchers (n = 72). Those from medical schools (n = 128) had more publications (p = .004) as did applied researchers in medical school compared to applied researchers from other faculties (p = .001). These findings provide early empirical insights into emerging tensions in environments where Mode I and Mode II activities co-exist; tensions that may extract unintended costs from researchers. Such costs may be paid in the currency not only of tenure and promotion, but also of successful grant and career scientist award acquisition.  相似文献

This study examined the perceptions of alternate-route and college-prepared teachers about the adaptation of mathematics and writing curriculum to student diversity. Findings from analyses of survey and interview data suggest that while at any given time a majority of teachers from both groups favored curriculum adaptation in mathematics and writing, commitment to these beliefs among individual teachers was inconsistent over time, with a pattern of deflected responsibility emerging. With the exception of two specific teachers, when discussing the value of adapting writing curriculum to students' cultural values, neither group of teachers went much beyond a general rhetorical discussion. With regard to mathematics, both groups of teachers only infrequently discussed the value of adapting mathematics to students' cultural values.  相似文献

A pool of 116 14-18-year-old secondary school pupils who had been given the computer-presented Cognitive Styles Analysis was used to provide two sub-samples to explore the relationship between style and motor skills and sports performance. The Motor Skills sub-sample of 69 (32 males and 37 females) did a battery of motor skills tests. A factor analysis suggested four skills factors - bodily movement, interactive skills, mechanical skills and aiming. All of these except the mechanical skills showed a significant relationship to style. The Sports Performance sub-sample of 99 (46 males and 53 females) were rated on a five-point scale by their teachers on performance in rugby, soccer and cricket for the boys, and hockey, netball and tennis for the girls. Here, there was a significant effect of style for tennis but not for the team games. The findings were discussed in terms of their practical implications.  相似文献

Despite the expansion of access toAustralian higher education in the past decade, theparticipation shares of rural and isolated people andpeople from lower socioeconomic backgrounds havealtered little and remain unacceptably low. Thispaper reports findings from two national studies atthe Centre for the Study of Higher Education that haveexamined student choices about higher education,especially the inhibiting factors still present fornon-traditional students. The discussion focuses onthe dilemmas and challenges for Australianuniversities in balancing the adoption ofentrepreneurial approaches to student recruitment withan unfinished equity agenda. The paper raisesquestions about the new ideology of individual choiceinfluencing university policy and whether or not thiscan be reconciled with social equity objectives.  相似文献

Electronic signatures, a means of verifying the identity of the user of a computer system to control access or authorize a transaction, are increasingly being used in electronic commerce. Several technologies can be used to produce electronic signatures, the most prominent being digital signatures, which use cryptographic techniques to provide data integrity and nonrepudiation. Legislation enacted in the 106th Congress enables the legal recognition of electronic signatures in interstate commerce. Other legislation introduced would promote federal agency use of electronic signatures to enable electronic filing of information.  相似文献

The SERVQUAL measure was developed by Parasuraman, Berry, and Zeithaml (SERVQUAL: A multiple-item scale for measuring customer perceptions of service quality. Journal of Retailing, 64, 12–40) to measure perceptions of service quality, originally in the retailing sector. Libraries and other educational institutions, however are also service providers. Librarians, in particular, have recently become increasingly interested in measuring quality of service as the ultimate assessment of library performance, as against more traditional measures of performance such as mere counts of various holdings. The present study explored SERVQUAL score validity in the library service context using data from 596 users representing three user groups and measurement at three times over six years. Second-order factor analysis provided mixed results as regards the psychometric integrity of SERVQUAL scores applied within the library service context.  相似文献

The aim of this longitudinal study was to further ourunderstanding of the reasons for social classdifferences in growth of decoding and readingcomprehension skills from beginning kindergarten throughchildren's fourth grade year. Participants wereenrolled in five public schools in a moderately sizedsouthern American city (n = 197). We examined ifbeginning kindergarten levels of three kinds ofreading related abilities explained social classdifferences in growth of reading skills during thetime periods of beginning kindergarten to children'sfirst-, second-, third-, and fourth-grade years. Thereading related abilities were phonological awareness,rate of access to phonological information inlong-term memory, and print knowledge. We found thatthe reasons for social class differences in growth ofreading skills depended on the time interval that wasconsidered. During the earliest time interval, socialclass differences in growth of decoding skills werecompletely accounted for by performance on the controlmeasures of general verbal intelligence and prior wordreading skills. During the remaining time periods,social class differences in growth of decoding andreading comprehension skills persisted whenperformance on the three kinds of reading relatedabilities and the control measures were accounted for. The greatest attenuation of SES differences in growthof reading skills occurred when beginning kindergartenlevels of print knowledge were taken into account.  相似文献

Children with hyperlexia read words spontaneously before the age of five, have impaired comprehension on both listening and reading tasks, and have word recognition skill above expectations based on cognitive and linguistic abilities. One student with hyperlexia and another student with higher word recognition than comprehension skills who started to read words at a very early age were followed over several years from the primary grades through high school when both were completing a second-year Spanish course. The purpose of the present study was to examine the foreign language (FL) word recognition, spelling, reading comprehension, writing, speaking, and listening skills of the two students and another high school student without hyperlexia. Results showed that the student without hyperlexia achieved higher scores than the hyperlexic student and the student with above average word recognition skills on most FL proficiency measures. The student with hyperlexia and the student with above average word recognition skills achieved higher scores on the Spanish proficiency tasks that required the exclusive use of phonological (pronunciation) and phonological/orthographic (word recognition, spelling) skills than on Spanish proficiency tasks that required the use of listening comprehension and speaking and writing skills. The findings provide support for the notion that word recognition and spelling in a FL may be modular processes and exist independently of general cognitive and linguistic skills. Results also suggest that students may have stronger FL learning skills in one language component than in other components of language, and that there may be a weak relationship between FL word recognition and oral proficiency in the FL.  相似文献
