The controversy surrounding the role of competitive sports in the development of eating disorders has increased in recent decades. There are inconsistent findings in the literature concerning the relationship between eating disorders and competitive sports, especially aesthetic sports. The aim of this study was therefore to assess eating disorder-related psychopathology in a sample of competitive figure skaters (FS) representative for competitive aesthetic sports. Special attention is paid to the investigation of body image and body satisfaction. Patients with anorexia nervosa (AN) and a healthy control group (CG) served as comparison groups. None of the FS met the complete diagnostic criteria for an eating disorder. Furthermore no significant differences were observed between the FS and the CG regarding body image and body satisfaction. However, a significant difference was detected compared to the AN patients. Our results underline the necessity for a differentiated analysis and careful diagnostics of sport-specific aspects when considering eating disorder-related psychopathology in competitive sports.  相似文献   

Teaching High School Biology Students to Coordinate Text and Diagrams: Relations with Transfer,Effort, and Spatial Skill     

Bradley W. Bergey  Jennifer G. Cromley  Nora S. Newcombe 《International Journal of Science Education》2013,35(15):2476-2502

There is growing evidence that targeted instruction can improve diagram comprehension, yet one of the skills identified in the diagram comprehension literature—coordinating multiple representations—has rarely been directly taught to students and tested as a classroom intervention. We created a Coordinating Multiple Representation (CMR) intervention that was an addition to an intervention focused on Conventions of Diagrams (COD) and tested their joint effects on diagram comprehension for near transfer (uninstructed biology diagrams), far transfer (uninstructed geology diagrams), and content learning (biology knowledge). The comparison group received instruction using a previously validated intervention that focused exclusively on COD. Participants were 9th–10th grade biology students (N?=?158 from two schools), whose classes were randomly assigned to COD alone or COD?+?CMR conditions and studied with a pretest–posttest experimental design. Both groups showed significant growth in biology knowledge (d?=?.30–.53, for COD and COD?+?CMR, respectively) and biology diagram comprehension (d?=?.28–.57). Neither group showed far transfer. Analyses of student work products during the interventions suggest that gains were not simply due to the passage of time, because student effort was correlated with gains in both treatment groups. Directions for improving future CMR interventions are discussed.  相似文献   

An Epistemic Frame Analysis of Neoliberal Culture and Politics in the US, UK, and the UAE     

Carol A. Mullen  Eugenie A. Samier  Sue Brindley  Fenwick W. English  Nora K. Carr 《Interchange》2013,43(3):187-228

Neoliberalism is a loosely knit bricolage from economics, politics, and various forms of reactionary populism that can be envisioned as a kind of epistemic frame in which largely counterrevolutionary forces engage in the creative destruction of institutional frameworks and powers, forging divisions across society that include labor and social relations (Harvey, A brief history of neoliberalism, 2009). Such “creative destruction” implies that neoliberalism is actually a reactionary “catalog of mind” (Robin, The reactionary mind: Conservatism from Edmund Burke to Sarah Palin, 2011, p. 17); that when believers engage in reactions to programs and ideas which represent what Bourdieu (Acts of resistance: Against the tyranny of the market, 1998) called “the left hand of the state” (typically represented by teachers, judges, social workers), one result has been the “involution of the state” (p. 34) and the “destruction of the idea of public service” (Bourdieu, The abdication of the state. In P. Bourdieu (Ed.), The weight of the world: Social suffering in contemporary society, 1999, p. 182). We examine neoliberalism using Shaffer’s (Int J Learn Media 1(2):1–21, 2009) concept of an “epistemic frame” based on the epistemic frame hypothesis that suggests that a community of practice has a culture, and that the collection of values, skills, knowledge, and identity form the “epistemic frame” (p. 4). An epistemic frame has a kind of grammar and structure comprised of people’s thoughts and actions, reinforced by the ways that people see themselves, the values to which they hold, and the epistemology that binds together their agenda. The purpose of our analysis is to create a praxis for what has been termed Regressionsverbot, which is defined as “a ban on backward movement with respect to social gains at the European level” (Bourdieu, Acts of resistance: Against the tyranny of the market, 1998, p. 41). In the form of cases from the United States, the United Kingdom, and the United Arab Emirates, neoliberal initiatives are examined, unpacked, and interrogated.  相似文献   

Innovations in Doctoral Education: Distance Education Methodology Applied     

Joanna Bettmann PhD  Kimberly Thompson  Nora Padykula  Joan Berzoff 《Journal of Teaching in Social Work》2013,33(3):291-312

This study evaluated the impact of a distance education program to meet the practice learning needs of first‐year doctoral students. The program, a six‐session case‐based telephonic seminar, was taught to 19 first‐year doctoral students. Evaluation of the program included self‐report quantitative and qualitative data gathered pre‐ and postseminar, as well as qualitative data gathered three months postseminar. Quantitative and qualitative analysis revealed increased reports of practice competencies by the conclusion of the seminar. Analysis also illustrated the importance of continued evaluation given the small sample size and pilot nature of this unique distance education program.  相似文献   

Taking Shape: Supporting Preschoolers' Acquisition of Geometric Knowledge Through Guided Play     

Kelly R. Fisher  Kathy Hirsh‐Pasek  Nora Newcombe  Roberta M. Golinkoff 《Child development》2013,84(6):1872-1878

Shape knowledge, a key aspect of school readiness, is part of early mathematical learning. Variations in how children are exposed to shapes may affect the pace of their learning and the nature of their shape knowledge. Building on evidence suggesting that child‐centered, playful learning programs facilitate learning more than other methods, 4‐ to 5‐year‐old children (N = 70) were taught the properties of four geometric shapes using guided play, free play, or didactic instruction. Results revealed that children taught shapes in the guided play condition showed improved shape knowledge compared to the other groups, an effect that was still evident after 1 week. Findings suggest that scaffolding techniques that heighten engagement, direct exploration, and facilitate “sense‐making,” such as guided play, undergird shape learning.  相似文献   

English language learners with reading-related LD: linking data from multiple sources to make eligibility determinations     

Wilkinson CY  Ortiz AA  Robertson PM  Kushner MI 《Journal of learning disabilities》2006,39(2):129-141

Results are reported for an exploratory study of eligibility decisions made for 21 Spanish-speaking English language learners (ELLs) with learning disabilities (LD) and no secondary disabilities who received special education support in reading. Eligibility determinations by an expert panel resulted in decisions that differed significantly from those of school multidisciplinary teams. The panel agreed that some students appeared to have reading-related LD (n = 5) but also identified students that they believed had disabilities, but not necessarily reading-related LD (n = 6). Another group of students (n = 10) had learning problems that the panel believed could be attributed to factors other than LD or for whom substantive additional data would be required to validate eligibility. Issues associated with referral, assessment, and eligibility determinations for ELLs are discussed, and recommendations for improving practice are offered, with an emphasis on the importance of linking data from multiple sources when deciding whether ELLs qualify for special education.  相似文献   

Mediation role of cardiorespiratory fitness on the association between fatness and cardiometabolic risk in European adolescents: The HELENA study

PurposeThis study was aimed to analyze the mediation role of cardiorespiratory fitness (CRF) on the association between fatness and cardiometabolic risk scores (CMRs) in European adolescents.MethodsA cross-sectional study was conducted in adolescents (n = 525; 46% boys; 14.1 ± 1.1 years old, mean ± SD) from 10 European cities involved in the Healthy Lifestyle in Europe by Nutrition in Adolescence study. CRF was measured by means of the shuttle run test, while fatness measures included body mass index (BMI), waist to height ratio, and fat mass index estimated from skinfold thicknesses. A clustered CMRs was computed by summing the standardized values of homeostasis model assessment, systolic blood pressure, triglycerides, total cholesterol/high-density lipoprotein cholesterol ratio, and leptin.ResultsLinear regression models indicated that CRF acted as an important and partial mediator in the association between fatness and CMRs in 12–17-year-old adolescents (for BMI: coefficients of the indirect role β = 0.058 (95% confidence interval (95%CI): 0.023–0.101), Sobel test z = 3.11 (10.0% mediation); for waist to height ratio: β = 4.279 (95%CI: 2.242–7.059), z =3.86 (11.5% mediation); and for fat mass index: β = 0.060 (95%CI: 0.020–0.106), z = 2.85 (9.4% mediation); all p < 0.01).ConclusionIn adolescents, the association between fatness and CMRs could be partially decreased with improvements to fitness levels; therefore, CRF contribution both in the clinical field and public health could be important to consider and promote in adolescents independently of their fatness levels.  相似文献

Winners and Losers' in the Development of Home-School Literacy Partnerships: An Analysis of Discourses of Power     

Trevor H. Cairney  Dr Nora L. White 《English in Education》1999,33(3):82-102

In the past decade, family literacy has been the focus of considerable research. This work has suggested multiple understandings of involvement, and that many schools tend to work within a definition of parent involvement that does little more than seek to conform parents and their children to the literacy practices of schools. This paper reports research that has considered how parents take strategic action on their own and their children's behalf to increase their educational opportunities. It looks closely at the ways relationships between families and schools are constructed, and presents two ‘telling cases’ of families' responses to school literacy practices assigned for work at home. In doing so, it attempts to bring voices from Australia to the dialogue on ways of viewing parental involvement. It does this from a community centred perspective with the focus on the process of constructing shared meanings and understandings. The research examines the specific literacy practices that are honoured and dishonoured in the name of ‘parent involvement’. In doing so, the paper attempts to make visible the potential ‘winners’ and ‘losers’ in the development of home-school literacy partnerships.  相似文献   

Deconstructing Building Blocks: Preschoolers' Spatial Assembly Performance Relates to Early Mathematical Skills     

Brian N. Verdine  Roberta M. Golinkoff  Kathryn Hirsh‐Pasek  Nora S. Newcombe  Andrew T. Filipowicz  Alicia Chang 《Child development》2014,85(3):1062-1076

This study focuses on three main goals: First, 3‐year‐olds' spatial assembly skills are probed using interlocking block constructions (N = 102). A detailed scoring scheme provides insight into early spatial processing and offers information beyond a basic accuracy score. Second, the relation of spatial assembly to early mathematical skills was evaluated. Spatial skill independently predicted a significant amount of the variability in concurrent mathematical performance. Finally, the relation between spatial assembly skill and socioeconomic status (SES), gender, and parent‐reported spatial language was examined. While children's performance did not differ by gender, lower SES children were already lagging behind higher SES children in block assembly. Furthermore, lower SES parents reported using significantly fewer spatial words with their children.  相似文献
