Physiological profile of a professional boxer preparing for Title Bout: A case study     

Israel Halperin  Steven Hughes  Dale W Chapman 《Journal of sports sciences》2016,34(20):1949-1956

This study aimed to (1) profile a professional boxer (23 years and 80 kg) with boxing-specific, muscle function, aerobic capacity and body composition tests, and (2) quantify how these measures varied during an 8-week preparation phase leading to, and post a state-Title Bout fought in the 76.2-kg class. A series of boxing-specific and muscle function tests were completed on 11 occasions: 9 prior and twice after the bout, each separated by approximately 2 weeks. The boxing test included 36 maximal punches (9 of each: lead and rear straights, lead and rear hooks) to a punching integrator measuring forces and velocity. Muscle function tests included countermovement jump, drop-jumps, isometric mid-thigh pull and isometric bench-press. Body composition was assessed using skin-fold measurements on three occasions and one dual energy X-ray absorptiometry scan. Aerobic capacity was assessed using 2 VO₂ max tests. Leading up to the bout, performance decreased in isometric mid-thigh pull (8%), isometric bench-press (5%), countermovement jump (15%) and impact forces in 3 of 4 punches (4%–7%). Whereas measures of dynamic and isometric muscle function remained depressed or unchanged post competition, punching forces (6%–15%) and aerobic power (6%) increased. Data suggest the athlete may have super-compensated following rest as fatigue dissipated and further adaptation occurred.  相似文献   

Collaborative Development and Evaluation of an Online Nursing Course     

Judith W. Alexander  Vera Polyakova-Norwood  Linda W. Johnston  Patricia Christensen  Renatta S. Loquist 《Distance Education》2003,24(1):41-56

Institutions of higher education acknowledge that online learning represents a growing segment of the modern learning environment, and most students have mastered basic computer skills. However, reluctance to engage in online learning remains among both faculty and students. This article presents a case study of three schools of nursing that collaboratively developed and implemented an online undergraduate-nursing course. The article discusses the challenges that were encountered by faculty and students. The faculty used the distance education literature to address these challenges related to technological, institutional, and pedagogical aspects of online learning, as well as the recruitment and retention of online learners. Quantitative and qualitative methods were used to evaluate the effectiveness of the course. The paper concludes with suggestions to overcome the challenges of online learning, such that faculty and students receive the inherent rewards.  相似文献   

Understanding student pathways in context-rich problems     

Pavlo D. Antonenko  Craig A. Ogilvie  Dale S. Niederhauser  John Jackman  Piyamart Kumsaikaew  Rahul R. Marathe  Sarah M. Ryan 《Education and Information Technologies》2011,16(4):323-342

This paper describes the ways that students’ problem-solving behaviors evolve when solving multi-faceted, context-rich problems within a web-based learning environment. During the semester, groups of two or three students worked on five physics problems that required drawing on more than one concept and, hence, could not be readily solved with simple “plug-and-chug” strategies. The problems were presented to students in a data-rich, online problem-based learning environment that tracked which information items were selected by students as they attempted to solve the problem. The students also completed a variety of tasks, like entering an initial qualitative analysis of the problem into an online form. Students were not constrained to complete these tasks in any specific order. As they gained more experience in solving context-rich physics problems, student groups showed some progression towards expert-like behavior as they completed qualitative analysis earlier and were more selective in their perusal of informational resources. However, there was room for more improvement as approximately half of the groups still completed the qualitative analysis task towards the end of the problem-solving process rather than at the beginning of the task when it would have been most useful to their work.  相似文献   

Genetic influences in different aspects of language development: the etiology of language skills in 4.5-year-old twins     

Kovas Y  Hayiou-Thomas ME  Oliver B  Dale PS  Bishop DV  Plomin R 《Child development》2005,76(3):632-651

The genetic and environmental etiologies of diverse aspects of language ability and disability, including articulation, phonology, grammar, vocabulary, and verbal memory, were investigated in a U.K. sample of 787 pairs of 4.5-year-old same-sex and opposite-sex twins. Moderate genetic influence was found for all aspects of language in the normal range. A similar pattern was found at the low end of the distribution with the exception of two receptive measures. Environmental influence was mainly due to nonshared factors, unique to the individual, with little influence from shared environment for most measures. Genetic and environmental influences on language ability and disability are quantitatively and qualitatively similar for males and females.  相似文献   

Child developmental impact of Pittsburgh’s Early Childhood Initiative (ECI) in high-risk communities: first-phase authentic evaluation research     

Stephen J. Bagnato  Hoi K. Suen  Dale Brickley  Janell Smith-Jones  Ernie Dettore 《Early childhood research quarterly》2002,17(4):117

The national debate surrounding the issue of school failure has renewed interest in the quality, efficacy, and outcomes of early childhood intervention programs that can promote early school success for children at developmental risk. Moreover, researchers and policymakers report the need to document developmentally-appropriate models for assessing and evaluating early childhood outcomes. We report on the first-phase results of Pittsburgh’s early childhood initiative (ECI). ECI is a privately-funded effort by a consortium composed of the business, corporate, foundation, and community sectors to implement high-quality early care and education options for children in high-risk neighborhoods. The overarching objective of ECI is to ensure early school success for high-risk children. Our Scaling Progress in Early Childhood Settings (SPECS) Evaluation Team implemented an authentic assessment and program evaluation strategy and an enhanced “constructed comparison group” statistical model to conduct longitudinal research on the child developmental impact of the ECI model. First-phase results on 155 high-risk children indicate that those who participated in high-quality ECI programs for the longest periods of time demonstrated patterns of progress that exceeded maturational expectations. Weekly collaborative consultation to teachers and caregivers by consultants about program quality using the National Association for the Education of Young Children (NAEYC) standards as “best practice” benchmarks seemed to be associated with initial enhanced child outcomes and the particular impact of the ECI model.  相似文献   

The effects of college grade adjustments on the predictive validity and utility of SAT scores     

Dana Keller  James Crouse  Dale Trusheim 《Research in higher education》1994,35(2):195-208

Regressing adjusted grade-point averages on freshman SAT scores and high school grade-point averages results in large increases in the incremental predictive validity of the SAT. Even so, the SAT still changes no more than a small proportion of admissions decisions and does not result in substantively important increases in freshman grades. The test does, however, change the composition of the freshman class by altering acceptances to some major areas of study and by limiting the access of women and blacks.  相似文献   

Early Mathematical Growth: How to Support Young Children’s Mathematical Development     

Filiz Varol  Dale C. Farran 《Early Childhood Education Journal》2006,33(6):381-387

The purpose of this critical analysis was to investigate the young children’s sense of numerical magnitudes and the important attributes of classrooms where children in kindergarten and first grade are exposed to mathematics. This study aimed to offer guidelines that will assist teachers as they teach mathematics to children between the ages of five and seven.  相似文献
