ABSTRACT

This study compared five different methods for analyzing accelerometer-measured physical activity (PA) in older adults and assessed the relationship between changes in PA and changes in physical function and depressive symptoms for each method. Older adult females (N = 144, M_age = 83.3 ± 6.4yrs) wore hip accelerometers for six days and completed measures of physical function and depressive symptoms at baseline and six months. Accelerometry data were processed by five methods to estimate PA: 1041 vertical axis cut-point, 15-second vector magnitude (VM) cut-point, 1-second VM algorithm (Activity Index (AI)), machine learned walking algorithm, and individualized cut-point derived from a 400-meter walk. Generalized estimating equations compared PA minutes across methods and showed significant differences between some methods but not others; methods estimated 6-month changes in PA ranging from 4 minutes to over 20 minutes. Linear mixed models for each method tested associations between changes in PA and health. All methods, except the individualized cut-point, had a significant relationship between change in PA and improved physical function and depressive symptoms. This study is among the first to compare accelerometry processing methods and their relationship to health. It is important to recognize the differences in PA estimates and relationship to health outcomes based on data processing method.

The Migration of African-Americans to the Canadian Football League During the 1950s: An Escape from Racism?     

Neil Longley  Todd Crosset  Steve Jefferson 《国际体育史杂志》2013,30(10):1374-1397

It is the argument of this paper that the literature on mid-century racial discrimination in sport is incomplete in that it ignores the experiences of a small, but relatively significant, group of African-American football players who actually chose to leave their own country – and correspondingly leave the racially-charged environment of mid-twentieth-century USA – to head north to play professional football in the Canadian Football League (CFL). Beginning in 1946, a steady flow of African-Americans began to migrate to the CFL which, at the time, was a legitimate competitor league to the NFL. This paper attempts to test a perception seemingly held by some that, by moving to Canada, African-American football players were able to escape the racial injustices they often suffered in the US. This view appears to have its roots in the notion that Canada is a ‘gentler’, more tolerant society, without the divisive socio-political history that characterizes much of the race relations in the US. This paper tests these notions using a variety of empirical approaches. The results indicate that, while African-Americans were better represented in the CFL relative to the NFL, African-Americans still faced some level of entry discrimination in the CFL. In particular, African-American players in the CFL outperformed their white counterparts on numerous performance dimensions, indicating the overall talent level in the CFL could have been further improved by employing an even greater number of African-Americans. Additionally, the paper finds that those CFL teams that employed the highest percentage of African-Americans were those teams that had the most on-field success. Finally, the paper analyses prices of player trading cards from that era, and finds that cards of African-Americans were undervalued, relative to white CFL players of equal talent.  相似文献   

Physiological Effects of Deep Water Running following a Land-Based Training Program     

Timothy J. Quinn PhD  Daniel R. Sedory  Brian S. Fisher 《Research quarterly for exercise and sport》2013,84(4):386-389

Abstract

The purpose of this study was to examine differences in knowledge representation and problem solutions in expert and novice youth baseball players. Ninety-four players in two age divisions, 7–8 years of age and 9–10 years of age, were assigned to three levels of expertise: high; average; and low skilled. Each subject participated in an interview session to elicit knowledge representation and solutions to five different defensive game situations. Interviews were transcribed and analyzed for content, solution to the problem, errors in problem solution, and qualitative trends. The frequency of advanced solutions to each of the five situations were analyzed in separate chi-square tests for age and expertise. Differences among the levels of expertise were found for the accuracy of solutions to three complex situations. Age was significant for only one situation. Patterns of knowledge content accessed during advanced and less advanced responses indicated both experts and novices were in a beginning stage of developing baseball knowledge structures. Errors in problem solutions indicated children had difficulty monitoring critical conditions and making correct inferences. Players' and teammates' ability to execute baseball skills seemed to influence the content and structure of tactical knowledge accessed during problem solution.  相似文献   

Stakeholders’ perceptions and recommendations of a high school leadership development programme for athletes in Singapore     

Koon Teck Koh  Leong Seng Morris Koh  Gordon A. Bloom  Todd M. Loughead 《Asia Pacific Journal of Education》2020,40(2):197-211

ABSTRACT

This study examined the perceptions of key stakeholders of a high school athlete leadership development training programme. Participants included 36 athletes (males = 23, females = 13) from two team sports (rugby n = 11 and volleyball n = 6) and two individual sports (bowling n = 8 and table tennis n = 11), as well as four coaches representing each of these sports and four teachers. Individual interviews were conducted for coaches, teachers, and athlete leaders, while athletes took part in focus group interviews. Inductive thematic analysis was used to analyse all data sets. Results showed that the athlete leadership programme developed qualities such as responsibility, role modelling, motivation, communication, perseverance, and team unity that would help athlete leaders perform their roles and responsibilities. The results also highlighted some limitations including earlier involvement from key stakeholders, tailored training for athlete leaders, and a more effective transfer of learning.  相似文献   

Physical discipline and children's adjustment: cultural normativeness as a moderator   总被引：2，自引：0，他引：2  

Lansford JE  Chang L  Dodge KA  Malone PS  Oburu P  Palmérus K  Bacchini D  Pastorelli C  Bombi AS  Zelli A  Tapanya S  Chaudhary N  Deater-Deckard K  Manke B  Quinn N 《Child development》2005,76(6):1234-1246

Interviews were conducted with 336 mother-child dyads (children's ages ranged from 6 to 17 years; mothers' ages ranged from 20 to 59 years) in China, India, Italy, Kenya, the Philippines, and Thailand to examine whether normativeness of physical discipline moderates the link between mothers' use of physical discipline and children's adjustment. Multilevel regression analyses revealed that physical discipline was less strongly associated with adverse child outcomes in conditions of greater perceived normativeness, but physical discipline was also associated with more adverse outcomes regardless of its perceived normativeness. Countries with the lowest use of physical discipline showed the strongest association between mothers' use and children's behavior problems, but in all countries higher use of physical discipline was associated with more aggression and anxiety.  相似文献

Transitioning to a more sustainable society: unpacking the role of the learning–action nexus     

Joanne M. Moyer  A. John Sinclair  Lisa Quinn 《International Journal of Lifelong Education》2016,35(3):313-329

In recent years, action on sustainability has been highly influential around the globe and many now recognize the importance of individual and social learning for inspiring action and achieving sustainability outcomes. Transformative learning theory has been criticized, however, for insufficient development of the link between learning and action. The purpose of this paper is to deepen our understanding of the learning–action cycle among adult learners in the sustainability context. We consider this through insights from two studies in Kenya and Canada, utilizing a qualitative approach. Both studies employed semi-structured interviews as their primary data collection instrument and used other tools such as focus groups and journal writing. Three broad nodes of social action—individual, interpersonal and collective—are identified and defined based on the data collected. Results show that while all three types of action were evident in the outcomes of participants, individual social action was the most common and collective social action was the least. Barriers to applying learning in action are also derived from the data, including situational, personal, interpersonal, sociocultural and environmental obstacles. Factors that assist in overcoming such barriers include community support networks and skills training.  相似文献   

Government,business and the public: The role of environmental education in creating sustainable urban places     

Muthoni Ngotho  Robert Fincham  Nevil Quinn 《Environmental Education Research》2004,10(3):313-329

This paper focuses on the need to further environmental education research within a context in which local government, local business and tertiary institutions are viewed as interlinked components of the development process. Research and interaction with local stakeholders offers an opportunity to chart a path that intersects and then fuses environmental education with that of environmental and development practice. The paper focuses on three research initiatives that highlight the intrinsic need to create a learning society and how to gain more robust recognition for the role of environmental education research as a developmental process. The three research initiatives deal with the integration of environmental management systems thinking in local government (case 1), how a local government envisaged environmental education campaign constitutes challenges for environmental education research (case 2), and how pollution highlights the need for partnerships in addressing the Polluter Pays Principle (case 3). Findings from the research underscore the lack of environmental concerns within the decision-making process in local government. Paucity of capacity to monitor and act on challenges within this sector also point to the need for coordinated action against industrial misdemeanours, where self-regulation is still far from a reality. Most importantly, we argue that environmental education research and practice should contribute to the strengthening of facilitation skills and systems thinking amongst researchers who work within networks of stakeholders who must ensure sustainable urban places in the future.  相似文献   

Influence of Verbal Working Memory Depends on Vocabulary: Oral Reading Fluency in Adolescents With Dyslexia     

L. Todd Rose  Parisa Rouhani 《Mind, Brain, and Education》2012,6(1):1-9

Most research on dyslexia to date has focused on early childhood, while comparatively little is known about the nature of dyslexia in adolescence. The current study had two objectives. The first was to investigate the relative contributions of several cognitive and linguistic factors to connected‐text oral reading fluency in a sample of adolescents with dyslexia (n = 77). The second was to test the hypothesis that the effect of verbal working memory on connected‐text oral reading fluency is moderated by word‐level skills and/or vocabulary knowledge. The results suggest that many deficits associated with childhood dyslexia remain prominent in adolescence, but the nature of the relationships between key cognitive and linguistic predictors (i.e., word‐level reading, vocabulary, verbal working memory) and reading fluency appear to be different in adolescence. For example, while word‐level skills remain a significant predictor, the strength of the effect is relatively weak. In contrast, the data support an increased role for vocabulary and verbal working memory, including an interaction between these factors. The presence of an interaction can be interpreted as evidence that the influence of verbal working memory on connected‐text oral reading fluency in adolescents with dyslexia depends on individual differences in vocabulary knowledge. These results offer support for the changing nature of dyslexia across development, and suggest that researchers should study dyslexia in adolescents on its own terms, rather than treating it as an extension of reading problems in early childhood.  相似文献
