Pacing profiles and pack running at the IAAF World Half Marathon Championships     

Brian Hanley 《Journal of sports sciences》2015,33(11):1189-1195

The aim of this study was to describe the pacing profiles and packing behaviour of athletes competing in the IAAF World Half Marathon Championships. Finishing and split times were collated for 491 men and 347 women across six championships. The mean speeds for each intermediate 5 km and end 1.1 km segments were calculated, and athletes grouped according to finishing time. The best men and women largely maintained their split speeds between 5 km and 15 km, whereas slower athletes had decreased speeds from 5 km onwards. Athletes were also classified by the type of packing behaviour in which they engaged. Those who ran in packs throughout the race had smaller decreases in pace than those who did not, or who managed to do so only to 5 km. While some athletes’ reduced speeds from 15 to 20 km might have been caused by fatigue, it was also possibly a tactic to aid a fast finish that was particularly beneficial to medallists. Those athletes who ran with the same competitors throughout sped up most during the finish. Athletes are advised to identify rivals likely to have similar abilities and ambitions and run with them as part of their pre-race strategy.  相似文献

Imagining the Journalist of the Future: Technological Visions of Journalism Education and Newswork     

Brian Creech  Andrew L. Mendelson 《The Communication Review》2015,18(2):142-165

Digitization has resulted in great uncertainty for journalism, leading to disruption of business models, revenue streams, media distinctions, and production practices. This uncertainty has led to many articles, reports, blog posts, and general commentary discussing the future of both journalism and the skills required by journalists to succeed in this environment. This essay analyzes these discourses, focusing specifically on the nature of technology as the sole determiner of journalism’s future, with interventions aimed at journalism education and the structure of newswork. An idealized notion of the technologically adept journalist, ready to usher in digital stability, emerges as the object of these debates and, thanks in large part to the limited scope and ahistorical character of digital discourse, obscures more persistent, systemic critiques of technology and journalism.  相似文献

For almost a half century David F. Treagust has been an exemplary science educator who has contributed through his dedication and commitments to students, curriculum development and collaboration with teachers, and cutting edge research in science education that has impacted the field globally, nationally and locally. A hallmark of his outstanding career is his collaborative style that inspires others to produce their best work.  相似文献   

The Efficacy of Using Diagrams When Solving Probability Word Problems in College   总被引：1，自引：1，他引：0  

Brian D. Beitzel  Richard K. Staley 《Journal of Experimental Education》2015,83(1):130-145

Previous experiments have shown a deleterious effect of visual representations on college students’ ability to solve total- and joint-probability word problems. The present experiments used conditional-probability problems, known to be more difficult than total- and joint-probability problems. The diagram group was instructed in how to use tree diagrams to solve conditional probability problems; the equation-only group was instructed only in the formulation of equations. Results indicated that the diagram group outperformed the equation-only group on a posttest of 10 near- and far-transfer problems given immediately and as long as 1 week later (Experiment 2). In addition, when rating their experience with the training phase the equation-only group reported significantly higher levels of frustration and lower levels of perceived success than the diagram group.  相似文献

A Critical Discourse Analysis of No Promo Homo Policies in US Schools     

Brian Barrett  Arron M. Bound 《Educational Studies A Journal of the American Educational Studies Association》2015,51(4):267-283

This article presents a critical discourse analysis of no promo homo policies and their effects in US schools. No promo homo—short for “no promotion of homosexuality” (Eskridge, 2000 Eskridge, W.N. (2000). No promo homo: The sedimentation of antigay discourse and the channeling effect of judicial review. New York Law Review, 75, 1327–1411.[Web of Science ®] , [Google Scholar], p. 1329)—polices have been adopted across nine states and several local school districts in the United States. They direct teachers and school officials to take a neutral position on the subject of sexual orientation and identity and often restrict or prohibit any school-based instruction, counseling, discussion, or activity that could be construed as being positive about or promoting homosexuality (Bonauto, n.d.; Cahill &; Cianciotto, 2004 Cahill, S., &; Cianciotto, J. (2004). US policy interventions that can make schools safer. Journal of Gay &; Lesbian Issues in Education, 2, 3–17.[Taylor &; Francis Online] , [Google Scholar]; Eskridge 2000 Eskridge, W.N. (2000). No promo homo: The sedimentation of antigay discourse and the channeling effect of judicial review. New York Law Review, 75, 1327–1411.[Web of Science ®] , [Google Scholar]). Our analysis suggests that, despite their claim to neutrality, no promo homo policies are actively harmful both to students who identify as lesbian, gay, bisexual, or transgender (LGBT) as well as to the broader school community. In an effort to ultimately promote healthier, more equitable school environments and experiences for all students, this article aims to raise awareness about the problematic effects of no promo homo policy language and the assumptions that often underlie it.  相似文献   

Genetic and Environmental Etiologies of the Longitudinal Relations Between Prereading Skills and Reading          下载免费PDF全文

The present study explored the environmental and genetic etiologies of the longitudinal relations between prereading skills and reading and spelling. Twin pairs (n = 489) were assessed before kindergarten (M = 4.9 years), post‐first grade (M = 7.4 years), and post‐fourth grade (M = 10.4 years). Genetic influences on five prereading skills (print knowledge, rapid naming, phonological awareness, vocabulary, and verbal memory) were primarily responsible for relations with word reading and spelling. However, relations with post‐fourth‐grade reading comprehension were due to both genetic and shared environmental influences. Genetic and shared environmental influences that were common among the prereading variables covaried with reading and spelling, as did genetic influences unique to verbal memory (only post‐fourth‐grade comprehension), print knowledge, and rapid naming.  相似文献   

When worlds collide: identity,culture and the lived experiences of research when ‘teaching-led’     

John G. Sharp  Brian Hemmings  Russell Kay  Carol Callinan 《Journal of Further & Higher Education》2015,39(5):612-644

This article presents detailed findings from the qualitative or interpretive phase of a mixed-methods case study focusing on the professional identities and lived experiences of research among six lecturers working in different capacities across the field of education in a ‘teaching-led’ higher education institution. Building upon the quantitative phase published earlier in this journal, factors both facilitating (e.g. research infrastructure, support for doctoral study) and constraining (e.g. time, space, workload, critical mass, ‘practitioner bond professionalism’, ‘organisational socialisation’, networks, roles and responsibilities, power relationships) research activity are identified. These are considered in the context of an institution often recruiting staff with ‘non-traditional’ backgrounds from within ‘the professions’ (e.g. from schools and colleges without doctorates) looking to become more ‘research-informed’ and establish a more vibrant and sustainable research culture. Recommendations for further development focus on ‘identity transitions’ and ‘cultural transformation’, emphasising the importance of research leadership and its distribution throughout the organisation. With current trends towards the apparent intensification and prioritisation of research activity over teaching, findings are considered particularly important for institutions of a similar nature to the one described here, for education departments in larger institutions also on similar journeys, and in light of an anticipated increase in demand for research activity arising from the expansion of higher education provision in further education and the private sector, where recruitment from within ‘the professions’ to teach across ‘vocational’ programmes is common.  相似文献
