The impact of different types of physical activity on total and regional bone mineral density in young Brazilian athletes     

Silva CC  Goldberg TB  Teixeira AS  Dalmas JC 《Journal of sports sciences》2011,29(3):227-234

Bone turnover is affected by exercise throughout the lifespan, especially during childhood and adolescence. The objective of this study was to investigate the impact of different sports on total and regional bone mineral density in male Brazilian adolescent athletes. Forty-six adolescents aged 10-18 years participated in the study: 12 swimmers, 10 tennis players, 10 soccer players, and 14 sedentary individuals. The athletes had engaged in physical activities for more than 10 h per week in the previous 6 months. Bone mineral density of the lumbar spine (L1-L4), left proximal femur region, and whole body was evaluated by dual-energy X-ray absorptiometry. Results showed higher mean values in the proximal femur region of tennis and soccer players (1.02 ± 0.18; 0.96 ± 0.16, respectively) than swimmers and controls (0.91 ± 0.14 and 0.87 ± 0.06, respectively) (P < 0.05). In relation to the impact of sporting activities based on bone age determination, we observed significant differences in bone mineral density at all evaluated sites at the end of puberty (16-18 years) compared with 10-12 years, with increases of 78% in the lumbar spine, 47% in the proximal femur, and 38% in the whole body.  相似文献

African American preschool children's physical activity levels in Head Start     

Shen B  Reinhart-Lee T  Janisse H  Brogan K  Danford C  Jen KL 《Research quarterly for exercise and sport》2012,83(2):168-174

The purpose of this study was to describe the physical activity levels of urban inner city preschoolers while attending Head Start, the federally funded preschool program for children from low-income families. Participants were 158 African American children. Their physical activity during Head Start days was measured using programmed RT-3 accelerometers. Results revealed that the children spent the most time in sedentary and light physical activity, while their participation in moderate-to-vigorous physical activities was low. Given the sedentary class format and limited physical space for the Head Start programs observed, we suggest adding a structured physical activity component to Head Start schools to fight the overweight and obesity crisis.  相似文献   

COURSE DROP PRACTICES IN TWO‐YEAR COLLEGES     

Arthur R. Southerland  Patricia Kramer Lowry 《Community College Journal of Research & Practice》2013,37(2):101-109

Course drop practices among two‐year colleges were surveyed. Examined were deadlines by which courses were dropped, grades received when classes were dropped, who initiates drop procedures, and the extent to which policies related to the above stated practices have been recently changed. One fourth of the institutions reported a drop deadline of between four and six weeks from the end of the term. Almost that many (21.98 percent) used 10 days prior to the final exam as a deadline. More than two‐thirds of the colleges allowed students to drop prior to the deadline with a non‐punitive “W” grade. In the majority of instances, the official drop procedures may be initiated by either the student or the instructor. Community college administrators need to examine course drop policies in light of institutional statements of mission, philosophy, and objectives. Based upon dialogue among the staff, appropriate policy revisions should be developed in order to coordinate the rhetoric and the regulations of the college.  相似文献   

Exploring Dialectical Tensions of Leading Volunteers in Two Community Choirs     

Cameron W. Piercy  Michael W. Kramer 《Communication Studies》2017,68(2):208-226

Leaders of volunteers face different challenges than leaders of paid employees due to different motivations and reward expectations. After synthesizing previous research applying dialectical theory to group members or leaders, this study examines the dialectical tensions that leaders of volunteers experienced and the communication they used to manage those tensions as reported by both the leaders and the volunteers. A constant-comparison method was used to analyze observations and interviews of members and leaders of two community choirs. The findings suggest that leaders of volunteers face eight dialectical tensions representing three broad categories: (a) task and relationship; (b) process and outcome; and (c) internal and external. Leaders negotiated these dialectical tensions through communication strategies including use of humor and appeals to artistic spirituality. These strategies represent hybridization and dualistic discourse rather than a monologic emphasis of one course of action over another.  相似文献   

Social Media in the Funeral Industry: On the Digitization of Grief     

Bjorn Nansen  Tamara Kohn  Michael Arnold  Luke van Ryn  Martin Gibbs 《广播与电子媒介杂志》2017,61(1):73-89

This article explores how innovations in the funeral industry borrow from the technological affordances, commercial logics, cultural norms, and affective registers of social media platforms. Based on ethnographic research of funeral industry conventions, we analyze examples of funeral planning tools, funeral service mediation, and digital memorialization products. We consider how these products aim to capture forms of data, affect, and value as part of the funeral industry’s efforts to shore up their historically intermediary relevance in the face of potential “disruption” from technological innovation, and threats of marginalization posed by shifting norms of networked grieving and commemoration in digital culture  相似文献   

A Little Autonomy Support Goes a Long Way: Daily Autonomy-Supportive Parenting,Child Well-Being,Parental Need Fulfillment,and Change in Child,Family, and Parent Adjustment Across the Adaptation to the COVID-19 Pandemic     

Andreas B. Neubauer  Andrea Schmidt  Andrea C. Kramer  Florian Schmiedek 《Child development》2021,92(5):1679-1697

This study examined the effects of daily parental autonomy support on changes in child behavior, family environment, and parental well-being across 3 weeks during the COVID-19 pandemic in Germany. Day-to-day associations among autonomy-supportive parenting, parental need fulfillment, and child well-being were also assessed. Parents (longitudinal N = 469; M_age = 42.93, SD_age = 6.40) of school children (6–19 years) reported on adjustment measures at two measurement occasions and completed up to 21 daily online questionnaires in the weeks between these assessments. Results from dynamic structural equation models suggested reciprocal positive relations among autonomy-supportive parenting and parental need fulfillment. Daily parental autonomy support, parental need fulfillment, and child well-being partially predicted change in adjustment measures highlighting the central role of daily parenting for children’s adjustment during the pandemic.  相似文献   

Addressing plagiarism in online programmes at a health sciences university: a case study     

Helen Ewing  Ade Anast  Tamara Roehling 《Assessment & Evaluation in Higher Education》2016,41(4):575-585

Plagiarism continues to be a concern for all educational institutions. To build a solid foundation for high academic standards and best practices at a graduate university, aspects of plagiarism were reviewed to develop better management processes for reducing plagiarism. Specifically, the prevalence of plagiarism and software programmes for detecting plagiarism was investigated. From that information, best practices for responding to plagiarism were developed and a process to enhance academic integrity was instituted. The results were impressive, the incidence of plagiarism offences reduced by half in three years, and by 75% among the English as a second-language student population.  相似文献
