Effects of Ventilation on Segmental Bioimpedance Spectroscopy Measures Using Generalizability Theory     

A. Allan Turner  Albert Lozano-Nieto  Marcel Bouffard 《Measurement in physical education and exercise science》2013,17(2):116-129

The purpose of this study was to examine the effect of three ventilation conditions (i.e., normal, regimented, and no-ventilation) on the reproducibility of bioimpedance scores in humans for the forearm and trunk segments. One hundred able-bodied North American men and women, from 18 to 71 years of age, volunteered as participants. The experimenters used a Xitron Bio-Impedance Analyzer System model 4200 instrument with Hydra software (Xitron Technologies, San Diego, California, USA) to collect bioimpedance data on extracellular fluid and intracellular fluid scores. The experimenters analyzed the data using the generalizability theory,with persons as the facet of differentiation and time as the facet of generalization. The major findings were (a) ventilation conditions did not have a significant impact on the reproducibility of the test scores, (b) the forearm segment produced consistently higher intracellular fluid generalizability coefficients across three ventilation conditions for both gender groups when compared to the trunk segment, (c) the trunk segment produced intracellular fluid generalizability coefficients that were higher for the male group, and (d) the measurement error affected extracellular fluid scores less than segmental intracellular fluid scores.  相似文献   

Agencies,educators, communities and wildfire: partnerships to enhance environmental education for youth     

Martha C. Monroe  Heidi L. Ballard  Annie Oxarart  Victoria E. Sturtevant  Pamela J. Jakes  Emily R. Evans 《Environmental Education Research》2016,22(8):1098-1114

We studied seven programs that engage youth from 10 to 18 years old in wildfire risk reduction in their communities in the United States through in-depth interviews to examine the nature and role of community-school partnerships in resource-focused environmental education. While the programs use a variety of strategies, from Scout badge to summer school, they exhibit several common dimensions: they all engage youth in community projects; they all arise from partnerships between resource agencies, community organizations, and educators; they all began when people familiar with both wildfire and youth education saw an opportunity to improve the community and educate youth through action; and all partners are able to contribute to the common program yet retain their individual identity as they meet their own mission-based goals. We use themes and quotes to illustrate these common dimensions for establishing community-school partnerships that could build action competence through environment-based education projects.  相似文献   

The link between text difficulty,reading speed and exploration of printed text during shared book reading     

Annie Roy-Charland  Melanie Perron  Krystle-Lee Turgeon  Nichola Hoffman  Justin A. Chamberland 《Reading and writing》2016,29(4):731-743

In the current study the reading speed of the narration and the difficulty of the text was manipulated and links were explored with children’s attention to the printed text in shared book reading. Thirty-nine children (24 grade 1 and 15 grade 2) were presented easy and difficult books at slow (syllable by syllable) or fast (adult reading speed) pace while their eye movements were monitored. Results revealed an interaction between speed and difficulty. For the easy and difficult books, children spent more time and made more fixations on the printed text when it was presented at slow speed than at fast speed. However, at fast speed, children spend more time and made more fixations on the text of the easy rather than the difficult books, but at slow speed no difference was observed. In addition, at slow speed positive correlations were observed between attention to print and letter knowledge and word reading skills. Results provide important information for the practice of shared book reading suggesting that to increase attention to print, speed should be reduced. Future research should investigate the role of reading speed on reading related outcomes such as discourse comprehension and children’s interest in reading activities.  相似文献   

Anxiety and cueing in a visual concept learning task     

Philip M. Turner 《Educational technology research and development : ETR & D》1983,31(1):47-53

This study investigated the relationship of two anxiety measures to performance on a visual concept acquisition task. Criterial information was embedded at two levels for the noncued treatment group and made salient by color cues for the cued treatment group. Two-way analyses of variance were used and indicated a significant interaction between cueing treatment andState-Trait Anxiety Inventory (stai) anxiety scores for the heavily embedded figures. Further research is suggested utilizing different populations and cueing techniques. The addition of cues is suggested for deeply embedded criterial information for use with high-anxiety students.  相似文献

Becoming a mature student: How adult appplicants weigh the advantages and disadvantages of higher education   总被引：1，自引：0，他引：1  

Michael Osborne  Andrew Marks  Eileen Turner 《Higher Education》2004,48(3):291-315

The data presented in this paper is taken fromthe results of two much larger studies ofmature student decision-making and HigherEducation (HE), which considerprocesses of agency from initial considerationof the possibility of becoming a studentto eventually becoming one. In thispaper, six categories of applicant to HE arediscussed: `Delayed traditional students', `Late starters' who have undergone alife-transforming event e.g. redundancy ordivorce and require `a new start'. `Single parents' `Careerists', who are currently in employment who seek a qualification to make progress in their existing careers, `Escapees' who are currently in employment who want a qualification as a way out of `dead-end' jobs, Finally, the `personal growers', a small number pursuing education for its own sake.These categories of applicants are discussed inlight of the factors that both catalyse andinhibit individuals' decision-making duringapplication to HE.  相似文献

Who benefits from student aid? The economic incidence of tax-based federal student aid     

Nicholas Turner 《Economics of Education Review》2012

Federal benefit programs, including federal student aid, are designed to aid targeted populations. Behavioral responses to these programs may alter the incidence of their benefits, a possibility that receives less attention in the literature compared to tax incidence. I demonstrate the importance of benefit incidence analysis by showing that the intended cost reductions of tax-based federal student aid are substantially offset by institutional price increases for a sample of 4-year colleges and universities. Contrary to the goal of policymakers, I find that tax-based aid crowds out institutional aid roughly dollar-for-dollar. Unfortunately, it is not clear how institutions utilize these captured resources, so that the ultimate incidence of the programs is uncertain.  相似文献   

Measuring patrons' technology habits: an evidence-based approach to tailoring library services     

Jin Wu  Amy J. Chatfield  Annie M. Hughes  Lynn Kysh  Megan Curran Rosenbloom 《Journal of the Medical Library Association》2014,102(2):125-129

Librarians continually integrate new technologies into library services for health sciences students. Recently published data are lacking about student ownership of technological devices, awareness of new technologies, and interest in using devices and technologies to interact with the library. A survey was implemented at seven health sciences libraries to help answer these questions. Results show that librarian assumptions about awareness of technologies are not supported, and student interest in using new technologies to interact with the library varies widely. Collecting this evidence provides useful information for successfully integrating technologies into library services.  相似文献
