Abstract

Items from the Reinvestment Scale were modified to create a decision-specific version of the scale. Principal components analysis of responses from 165 participants revealed one-, two-, three-, and four-factor solutions for the Decision-Specific Reinvestment Scale. Confirmatory factor analysis of responses from a second sample of 111 participants revealed that a 13-item two-factor solution showed the best fit. The first factor comprised six items referring to conscious monitoring of the process involved in making a decision, and was termed decision reinvestment. The second factor, decision rumination, comprised seven items related to focus on negative evaluations of previous poor decisions. In an initial assessment of predictive validity, Decision-Specific Reinvestment Scale scores of 59 skilled team sport players were found to be highly correlated with coaches' ratings of players' tendency to choke under pressure (r = 0.74), with high Decision-Specific Reinvestment Scale scores indicating greater susceptibility to poor decision-making under pressure. It was concluded that the Decision-Specific Reinvestment Scale highlights a performer's predisposition to engage in behaviours detrimental to performance under pressure, namely decision reinvestment and decision rumination.  相似文献

Purpose: From 1996 to 2013, a 6-day Physical Activity and Public Health Course for Practitioners has been offered yearly in the United States. An evaluation was conducted to assess the impact of the course on building public health capacity for physical activity and on shaping the physical activity and public health careers of fellows since taking the courses. Method: An evaluation quantified time that fellows spent in different course offerings and surveyed fellows. Results: From 1996 to 2012, 410 fellows attended the course, and in 2013, 186 participated in the Web-based survey (56% response rate). The number of fellows attending the course ranged from 15 to 33 yearly. From 1996 to 2012, the course averaged 38 hr of instructional time that included topics on interventions and environment/policy work to increase physical activity, program evaluation, public health research, and health disparities. The course included consultations, collaborative work, and field-based experiences. Fellows who participated in the survey agreed that the course had a positive impact on the physical activity research or practice work they did (98%), met their expectations (96%), helped them with research/practice collaborations with other physical activity professionals (96%), assisted them in conducting higher-quality interventions/programs (95%), helped increase their professional networking in the field (93%), and had a positive impact on other work they did (91%). Following the course, 66% and 56% had further contact with faculty and other fellows, respectively. Conclusion: The Physical Activity and Public Health Course for Practitioners made important contributions toward building the capacity of physical activity and public health practitioners.  相似文献

The wrist is the most frequently injured body region among snowboarders. Studies have shown that the risk of sustaining a wrist injury can be reduced by wearing wrist protection. Currently, there are a wide variety of wrist protection products for snowboarding on the market that offer a range of protective features. However, there are no minimum performance standards for snowboarding wrist protectors worldwide. The International Society for Skiing Safety convened a task force to develop a White Paper to evaluate the importance and necessity of a minimum performance for all wrist protectors used in snowboarding. The White Paper outlines the need for a general framework for a harmonized international standard and reviews the existing evidence. Therefore, this White Paper may serve as a common base for future discussions. The broader goal of developing and implementing such a standard is to reduce the incidence and the severity of wrist injuries in snowboarding without increasing the risk of adverse events, such as upper arm or shoulder injury. The European standard for inline skating wrist protectors (EN 14120) can serve as a starting point for efforts related to a standard for snowboard wrist protectors, but certain modifications to the standard would be required. It is hypothesized that implementation of a snowboarding wrist protector standard would result in fewer and less severe wrist injuries in the sport and could translate into more riding days for healthy snowboarders and significant health-care costs savings.  相似文献

Skating     
Technical evaluation in the sport of figure skating is characterized by a subjective marking system. Figure skating judges are responsible for quickly and accurately discerning the quality of technical elements as well as assigning a score to the overall aesthetic appearance of a performance. Traditionally, overall placement marks are assigned for the entire performance; however, the landing of a jump is widely acknowledged as one of the most critical elements of a skater's program. Therefore, our aims were to identify the biomechanical variables that contribute to technical success in executing landings and to establish whether landings rated as biomechanically optimal are also awarded high technical merit scores by judges. Ten nationally ranked competitive figure skaters were asked to execute on‐ice, double and triple revolution jumps and to try to land the jumps void of technical faults within a calibrated space. Data were collected at 60 Hz using standard three‐dimensional videography. Data reduction was done using the APAS system (Ariel Dynamics Inc). Concurrently, videotapes were viewed and evaluated by 42 accredited judges to determine the perceived technical quality of the landing performances. Judges were asked to evaluate the landing phase of each jump against a landing criteria document. A comparative criteria model was developed to facilitate an assessment of excellence in landing performances through both empirical and subjective analyses. Results of these analyses were twofold: a biomechanical profile of on‐ice landings was obtained, and on‐ice jump landing strategies rated by empirical evaluations were in agreement with judge's perceptions of the same performances.  相似文献

Using nationally representative data from the Family and Child Experiences Survey 2009 cohort (= 2,842), this study examined the implications of 3‐ and 4‐year‐old's absences from Head Start for their early academic learning. The findings from this study revealed that children who missed more days of school, and especially those who were chronically absent, demonstrated fewer gains in areas of math and literacy during the preschool year. Moreover, excessive absenteeism was found to detract from the potential benefits of quality preschool education and was especially problematic for the early learning of children who entered the Head Start program with a less developed skill set. Implications for policy and practice are discussed.  相似文献

ABSTRACT

Drawing from Black, feminist epistemologies as well as theories of critical consciousness, and adolescent digital literacies, this paper analyzes the narratives of 7 Black, female high school students who experience oppressive practices, including racial microaggressions, silencing, harsh discipline, and marginalization within a predominately White school environment. At this juncture in which race, politics, and activism intersect with school, media, and identity, this study discusses how Black, female students resist oppression and use digital and social media as well as other available tools to speak out against injustice and heighten the racial awareness of their school community. This qualitative case study uses individual and focus group interviews to examine the ways in which Black female students develop critical resistance strategies, working individually and collectively within existing structures to fight for their humanity and liberation.  相似文献

Rhyme generation in deaf students: the effect of exposure to cued speech   总被引:1,自引:0,他引:1  
This study compares the rhyme-generation ability of deaf participants with severe to profound hearing losses from cued speech (CS) and non-cued speech (NCS) backgrounds with a hearing comparison group for consistent orthography-to-phonology (O-P) rhyming elements, or rimes (e.g., -ail in sail is always pronounced the same), and inconsistent orthography-to-phonology (I-O-P) rhyming elements where the orthographic rime (e.g., -ear) has different pronunciations in words such as bear, and rear. Rhyming accuracy was better for O-P target words than for I-O-P target words. The performance of the deaf participants from CS backgrounds, although falling between that of the hearing and the NCS groups, did not differ significantly from that of the hearing group. By contrast, the performance of the NCS group was lower than that of the hearing group. Hearing and CS participants produced more orthographically different responses (e.g., blue-few), whereas participants from the NCS group produced more responses that are orthographically similar (e.g., blue-true), indicating that the hearing and CS groups rely more on phonology and the NCS group more on spelling to generate rhymes. The results support the use of cued speech for developing phonological abilities of deaf students to promote their reading abilities.  相似文献

We empirically evaluated the associations of hypothesized protective and risk factors with assessments of social, literacy, and cognitive competence in a sample of Head Start graduates attending kindergarten in rural Georgia. The sample included 117 former Head Start children and their primary caregivers, who were assessed during the fall of the children's kindergarten year. The participating families—59% African American, 39% white, and 1 % Latin American—lived in four rural counties in northeast Georgia. Data were obtained from caregivers, teachers, and children, using a multimethod, multi-informant research design. Caregivers provided information about developmental goals, family processes, and their own psychological functioning; and the children and their kindergarten teachers provided socioemotional, literacy, and cognitive-competence information. The results support the hypothesized relations between the child-competence measures and protective factors, especially caregiver self-esteem, endorsement of independence-promoting developmental goals, co-caregiver support and communication, and engaged, responsive, and cognitively challenging caregiver-child interactions. The results also support the hypothesis that caregiver distress and conflicted family relationships are associated with negative developmental outcomes for former Head Start children attending kindergarten.  相似文献
