The purpose of this study was to assess the reproducibility of body composition measurements by dual-energy X-ray absorptiometry (DXA) in 12 elite male wheelchair basketball players (age 31 ± 7 years, BMI 21 ± 2 kg/m2 and onset of disability 25 ± 9 years). Two whole body scans were performed on each participant in the supine position on the same day, using Lunar Prodigy Advance DXA (GE Lunar, Madison, WI, USA). Participants dismounted from the scanning table and were repositioned in-between the first and second scan. Whole body coefficient of variation (CV) values for bone mineral content (BMC), fat mass (FM) and soft tissue lean mass (LTM) were all <2.0%. With the exclusion of arm FM (CV = 7.8%), CV values ranged from 0.1 to 3.7% for all total body and segmental measurements of BMC, FM and LTM. The least significant change that can be attributed to the effect of treatment intervention in an individual is 1.0 kg, 1.1 kg, 0.12 kg for FM, LTM, and BMC, respectively. This information can be used to determine meaningful changes in body composition when assessed using the same methods longitudinally. Whilst there may be challenges in the correct positioning of an individual with disability that can introduce greater measurement error, DXA is a highly reproducible technique in the estimation of total and regional body composition of elite wheelchair basketball athletes. 相似文献

We propose an approach to enhancing knowledge sharing and connectedness in distributed teams. Termed ‘Narrating Your Work’ (NYW), the approach involves members of distributed team using a microblogging tool to post regular updates about their current work, accomplishments, and issues. The NYW approach was evaluated within a geographically and temporally distributed team at Shell International for a period of one month, using a mixed-method research design. Methodology comprised of a quantitative survey, followed by semi-structured interviews and analysis of microblogging updates posted during the month in which the approach was being trialled. The evaluation results suggest that NYW was viewed as a valid and practical approach to enhancing knowledge sharing and connectedness. A range of barriers and enablers that could impact the future application and embedding of the approach are identified and recommendations for implementation are outlined. 相似文献

Stickiness refers to the set of persuasive message properties: simple, unexpected, concrete, credible, emotional, and stories (SUCCES). Heath and Heath (2007) argue that a sticky message is expected to be more memorable and hence more persuasive than a non-sticky message. A 2 (sticky v. non-sticky message) x 3 (pretest v. posttest v. delayed test) longitudinal experiment is employed to examine the persuasiveness of sticky messages on applying sunscreen. Results of a mixed model analysis of variance show that the sticky message produces attitudes and behaviors more favorable to the message recommendation than the non-sticky message. Specifically, a time × message induction non-additive effect was found, which sustained only in the sticky message condition across time. Despite this interesting effect, its explanation remains elusive. 相似文献

Objective
The present study was designed to determine whether parents at high risk for physical child abuse, in comparison with parents at low risk, show deficits in emotion recognition, as well as to examine the moderator effect of gender and stress on the relationship between risk for physical child abuse and emotion recognition.Methods
Based on their scores on the Abuse Scale of the CAP Inventory (Milner, 1986), 64 parents at high risk (24 fathers and 40 mothers) and 80 parents at low risk (40 fathers and 40 mothers) for physical child abuse were selected. The Subtle Expression Training Tool/Micro Expression Training Tool ( [Ekman, 2004a] and [Ekman, 2004b]) and the Diagnostic Analysis of Nonverbal Accuracy II (Nowicki & Carton, 1993) were used to assess emotion recognition.Results
As expected, parents at high risk, in contrast to parents at low risk, showed deficits in emotion recognition. However, differences between high- and low-risk participants were observed only for fathers, but not for mothers. Whereas fathers at high risk for physical child abuse made more errors than mothers at high risk, no differences between mothers at low risk and fathers at low risk were found. No interaction between stress, gender, and risk status was observed for errors in emotion recognition.Conclusions and practice implications
The present findings, if confirmed with physical abusers, could be helpful to further our understanding of deficits in processing information of physically abusive parents and to develop treatment strategies specifically focused on emotion recognition. Moreover, if gender differences can be confirmed, the findings could be helpful to develop specific treatment programs for abusive fathers. 相似文献77.

High-fidelity anatomical models can be produced with three-dimensional (3D) scanning techniques and as such be digitally preserved, archived, and subsequently rendered through various media. Here, a novel methodology—digital body preservation—is presented for combining and matching scan geometry with radiographic imaging. The technique encompasses joining layers of 3D surface scans in an anatomical correct spatial relationship. To do so, a computed tomography (CT) volume is used as template to join and merge different surface scan geometries by means of nonrigid registration into a single environment. In addition, the use and applicability of the generated 3D models in digital learning modalities is presented. Finally, as computational expense is usually the main bottleneck in extended 3D applications, the influence of mesh simplification in combination with texture mapping on the quality of 3D models was investigated. The physical fidelity of the simplified meshes was evaluated in relation to their resolution and with respect to key anatomical features. Large- and medium-scale features were well preserved despite extensive 3D mesh simplification. Subtle fine-scale features, particular in curved areas demonstrated the major limitation to extensive mesh size reduction. Depending on the local topography, workable mesh sizes ranging from 10% to 3% of the original size could be obtained, making them usable in various learning applications and environments. 相似文献

A study of the relationships between students' questioning and learning styles is being conducted on data collected in two university semesters with a sample of 300 students. This report discusses the results of case studies looking in depth at four of the students. These were involved in further data collection through written and oral questions, interviews and classroom observation experiments. The main aim is to unravel the interrogative bases of the students' learning by looking at the quality and quantity of questions they ask. This means that among other characteristics, the nature and the deliberative or spontaneous use of questions by the four students were investigated. It was possible to distinguish question‐askers by tallying their questions. Their learning styles were characterised using Kolb's Learning Styles Inventory. The study also allowed for snapshots of how particular learners shape questions. Looking at the way in which these questioning styles fit with their orientations to learning, and how this drives learning, informs what teaching might best then ensue. 相似文献

通过对陈寅恪学术贡献与学术观点的评估、对陈寅恪人特征与化取向的剖析、对陈寅恪研究中几个问题的讨论、对全面评价陈寅恪的若干思考,可得出结论,陈寅恪存在理智与情感的尖锐矛盾,理智上能清醒地看到中国旧化必然歇绝的历史命运,情感上却无法摆脱对此化的深深眷恋。不仅陈寅恪的《诗集》,而且陈寅恪的全部作,都是对这一化的余音不绝的挽歌。陈寅恪的思想基础不是人本主义,而是民族主义、国家主义,他所追求和维护的不是“天下万世的真理”,而是囿于一时间(前现代)、一地域(封建中国)的终将归于不可救疗之局的纲常名教。陈寅恪不是一个真正的自由主义,而是一个坚定的保守主义。 相似文献

粤东高校篮球运动员赛前焦虑与场上表现的相关研究 总被引:2,自引:0,他引:2
本通过对粤东高校男子篮球赛中8支球队运动员赛前焦虑情绪和比赛中表现的测试评价,结果表明:运动员赛前状态焦虑情绪与场上技术发挥、特一状焦虑与投篮命中关系密切,过高焦虑(或状态焦虑)对技术发挥和成绩不利,与整体实力、场上配合、紧张的关系不密切。建议平时要加强对运动员的心理训练才能取得好成绩。 相似文献
