An Examination and Validation of an Adapted Youth Experience Scale for University Sport     

Scott Rathwell  Bradley W. Young 《Measurement in physical education and exercise science》2016,20(4):208-219

Limited tools assess positive development through university sport. Such a tool was validated in this investigation using two independent samples of Canadian university athletes. In Study 1, 605 athletes completed 99 survey items drawn from the Youth Experience Scale (YES 2.0), and separate a priori measurement models were evaluated (i.e., 99 items, YES 2.0, YES for Sport [YES-S]). Confirmatory factor analysis (CFA) and exploratory structural equation modeling (ESEM) results indicated issues with model fit. Post-hoc modifications improved fit, resulting in a 46-item, 9-factor model with five positive and four negative dimensions. In Study 2, 511 athletes completed the same items. The resultant model was confirmed using both CFA (comparative fit index [CFI] = .911, standardized root mean square residual [SRMR] = .056, root mean square error of approximation [RMSEA] = .040) and ESEM (CFI = .956, SRMR = .023, RMSEA = .034). The resultant University Sport Experience Survey provides a reliable and factorially valid instrument for measuring development in university sport.  相似文献   

The Impact of the Home Instructional Program for Preschool Youngsters (HIPPY) on School Performance in 3rd and 6th Grades     

Robert H. Bradley  Barbara Gilkey 《Early education and development》2002,13(3):301-312

A post hoc matching design was used to compare children who participated in the Home Instructional Program for Preschool Youngsters (HIPPY) throughout Arkansas to children from the same classrooms who had no preschool experience and children who had other preschool experiences in the third and sixth grades. The program showed modest positive impact on school suspensions, grades, classroom behavior, and achievement test scores at both grade levels.  相似文献

工艺创新机制研究:来自中国汽车企业的实证          下载免费PDF全文

李显君  高歌  孟东晖  章博文 《科研管理》2016,37(12):37-45

现有产品创新研究文献远远多于工艺创新文献,而对于工艺创新机制的研究更为少见。本文结合文献调研、专家访谈和汽车企业工艺实践,构建了汽车企业工艺创新机制理论模型和研究假设,利用结构方程模型对假设进行了检验。研究发现,决策机制对动力机制、组织机制和激励机制有正向作用,但决策机制对企业工艺创新能力没有直接影响;动力机制、组织机制直接影响工艺创新能力,动力机制的作用相对较弱;组织机制对激励机制的正向作用和激励机制对工艺创新能力的正向作用都没有通过检验。本文对丰富工艺创新研究具有重要的学术价值,研究成果有利于促进企业和政府加强对工艺创新重视。  相似文献   

What Does a Modern Anatomist Look like? Current Trends in the Training of Anatomy Educators     

Audra F. Schaefer  Adam B. Wilson  J. Bradley Barger  Homaira M. Azim  James J. Brokaw  William S. Brooks 《Anatomical sciences education》2019,12(3):225-235

Anatomical sciences are foundational to the health professions, yet little is known about the qualifications of anatomy educators at the graduate and professional level in the United States. Moreover, there is concern that the number of qualified anatomy educators being trained may be insufficient to meet the growing demand posed by new and expanded programs in medicine and allied health specialties. The authors surveyed anatomists from across the country to (i) characterize the educational credentials of current anatomy educators and (ii) assess the perceived need for education-focused postdoctoral positions or formal mentorships to prepare anatomists for teaching-intensive faculty positions. To probe the survey responses more deeply, one-on-one interviews were conducted with eight individuals selected to represent a diverse sample of respondents in terms of institution, gender, and academic rank. Results indicate that 30–40% of educators at the graduate level and approximately 60% of those at the undergraduate level lack graduate coursework in histology, embryology, and neuroanatomy. Forty-five percent of respondents had completed a postdoctoral fellowship. Eighty-six percent replied “yes/maybe” to the question of whether an anatomy education postdoctoral fellowship would benefit doctoral graduates. The top 3 reasons for this recommendation were to (i) establish independent educational research, (ii) improve a publication record, and (iii) gain additional teaching experience. Notable weaknesses of education-focused postdoctoral training were related to finances, fear of exploitation, and undervaluing of teaching. Moving forward, postdoctoral fellowships and other forms of postgraduate training may represent a key strategy for training anatomists in the current educational climate.

Preliminary norms and technical data for use of the Revised-Children's Manifest Anxiety Scale with kindergarten children     

Cecil R. Reynolds  Michael Bradley  Carol Steele 《Psychology in the schools》1980,17(2):163-167

The Revised-Children's Manifest Anxiety Scale (Reynolds & Richmond, 1978) was administered to 97 kindergarten children. Coefficient alpha reliabilities of .79 for males (N = 53), .85 for females (N = 44), and .82 for the total sample resulted. Contrary to findings with older children, no sex differences occurred in scoring on the anxiety scale. The kindergarten children generally scored higher on the anxiety scale than did older children. Lie scale scores were comparable to those of other primary grade children. Implications for use of the scale with young children are discussed.  相似文献   

The mediating role of intention and stages of change in physical activity among adults with physical disabilities: an integrative framework     

Kosma M  Ellis R  Cardinal BJ  Bauer JJ  McCubbin JA 《运动与训练心理学杂志》2007,29(1):21-38

The study's purpose was to identify the mediating role of intention and the stages of change (SOC) in physical activity (PA) over a 6-month period using two models (theory of planned behavior [TPB] and TPB/SOC). Participants were 143 adults with physical disabilities (70.68% response rate; M age = 46.03). The TPB constructs, SOC (time 1), and PA (time 2) were assessed using standardized self-report questionnaires. Based on path analyses, attitude had the highest effect on intention and SOC followed by perceived behavioral control within both well-fit models. The variance in PA explained by the first (TPB) and second (TPB/SOC) models was 16% and 28% respectively. In the just identified model of TPB/SOC, the direct effect of SOC on physical activity remained strong (gamma(soc.pa) = .45) and SOC approached full mediation through attitude. Health promotion interventions need to include both intention and behavior elements (SOC) reinforcing increased PA value and barrier elimination.  相似文献
