Tracing one's family genealogy is a complex process that requires situating a family's narratives within a historical context. This article reviews the use of critical family history research in an undergraduate Asian American studies course to examine not only the diversity and experiences of Asian Americans but also the unspoken narratives that lead to the creation of a single story. We are told single stories that often neglect the sociocultural factors—the historical reality—of our past. Our family histories are constructed historically and are embedded in social, political, and economic processes and relationships. This article argues that we need to complicate what we know about our past and examine policies and cultural practices that lead to a racialized system of power and privilege, racialized policies, and racialized oppression and progression.  相似文献

This qualitative, exploratory study examines issues of age and aging surrounding mega-serial (daily soap opera) production in Tamil Nadu, India. This study is timely for demographic reasons (a rapidly aging Indian population) and for the centrality of mega-serials to India’s entertainment landscape, coupled with the genre’s long history of engaging global audiences with real-world social issues. Two data sources are utilized: focus groups with 16 mega-serial viewers and interviews with 25 members of the Tamil mega-serial industry. Situated in scholarship on gerontology/age studies and media/culture industry studies, analysis yields two broad themes related to (a) representations of age/aging and elder-oriented storylines in contemporary Tamil mega-serials and (b) recent industry changes that may forestall mega-serials’ potential to center age and aging as core narrative elements. Overall, evidence points to an industry and audience(s) in considerable transition.  相似文献

The aim of this study was to ascertain if gear ratio selection would have an effect on peak power and time to peak power production in elite Bicycle Motocross (BMX) cyclists. Eight male elite BMX riders volunteered for the study. Each rider performed three, 10-s maximal sprints on an Olympic standard indoor BMX track. The riders’ bicycles were fitted with a portable SRM power meter. Each rider performed the three sprints using gear ratios of 41/16, 43/16 and 45/16 tooth. The results from the 41/16 and 45/16 gear ratios were compared to the current standard 43/16 gear ratio. Statistically, significant differences were found between the gear ratios for peak power (F(2,14)?=?6.448; p?=?.010) and peak torque (F(2,14)?=?4.777; p?=?.026), but no significant difference was found for time to peak power (F(2,14)?=?0.200; p?=?.821). When comparing gear ratios, the results showed a 45/16 gear ratio elicited the highest peak power,1658?±?221?W, compared to 1436?±?129?W and 1380?±?56?W, for the 43/16 and 41/16 ratios, respectively. The time to peak power showed a 41/16 tooth gear ratio attained peak power in ?0.01?s and a 45/16 in 0.22?s compared to the 43/16. The findings of this study suggest that gear ratio choice has a significant effect on peak power production, though time to peak power output is not significantly affected. Therefore, selecting a higher gear ratio results in riders attaining higher power outputs without reducing their start time.  相似文献

Abstract

The aim of the study was to explore the significance of the ‘timing’ of the quiet eye (QE), and the relative importance of late (online control) or early (pre-programming) visual information for accuracy. Twenty-seven skilled golfers completed a putting task using an occlusion paradigm with three conditions: early (prior to backswing), late (during putter stroke), and no (control) occlusion of vision. Performance, QE, and kinematic variables relating to the swing were measured. Results revealed that providing only early visual information (occluding late visual information) had a significant detrimental effect on performance and kinematic measures, compared to the control condition (no occlusion), despite QE durations being maintained. Conversely, providing only late visual information (occluding early visual information) was not significantly detrimental to performance or kinematics, with results similar to those in the control condition. These findings imply that the visual information extracted during movement execution – the late proportion of the QE – is critical when golf putting. The results challenge the predominant view that the QE serves only a pre-programming function. We propose that the different proportions of the QE (before and during movement) may serve different functions in supporting accuracy in golf putting.  相似文献

The purpose of the study was to investigate the effect of different kicking modality, i.e., erratic-dynamic target (EDT) versus static target (ST) on the performance of the roundhouse kick in two groups of taekwondo athletes of different skill level. Three-dimensional analysis and surface electromyography (SEMG) analysis were performed on 12 (Group A: six sub-elite, Group B: six elite) athletes to investigate muscle co-activation pattern under two conditions, i.e., EDT versus ST. In the results, the muscle recruitment ratio of the agonistic muscles was higher for Group A, whereas Group B had higher recruitment ratio for antagonist muscles. Overall, the co-activation index (CI) of hip joints appeared higher in the extensors for Group A, whereas higher CI was observed in flexor muscles for Group B with comparatively higher CI during EDT condition than ST condition. Higher value of CI was observed in flexor muscles of the knee joints among Group A during EDT conditions, in contrast, higher CI in the extensor muscles was observed among Group B during ST conditions. In conclusion, the study confirmed that erratic-dynamic movements of target could change the movement coordination pattern to maintain the joint stability of participants.  相似文献

Clutch performance is improved performance under pressure. However, little research has examined the psychological state experienced by athletes in these situations. Therefore, this study qualitatively examined the subjective experience underlying clutch performance across a range of sports (e.g., team, individual) and standards (Olympic to recreational athletes). Sixteen athletes (Mage = 27.08 years; SD = 6.48) took part in in-depth, semi-structured interviews primarily after an exceptional performance (M = 4.38 days later; SD = 3.14). Data were analysed inductively and thematically. Clutch states involved 12 characteristics, including heightened and deliberate concentration, intense effort, and heightened awareness, which distinguished the experience of clutch from other optimal psychological states such as flow. Other characteristics, such as perceptions of control, were also reported and supported previous experimental research on clutch. These findings present in-depth qualitative insights into the psychological state underlying clutch performance, and are discussed in relation to the existing literature on optimal psychological states in sport.  相似文献

This article reveals Native youth perspectives on socio-culturally responsive education. The authors draw on two studies conducted in the Southwest among Navajo and Pueblo students. Youth convey the importance of meaningful, reciprocal, and transformative learning experiences and relationships at school. The article ends with suggestions for creating a socio-culturally responsive school environment.  相似文献

Over the last decade in the UK, there has been a notable shift in the popularity and use of cultural mapping as a methodology for policy making at a regional and local level. This follows increased demand for an informed framework for planning arts and cultural facilities from local and regional government and from within the cultural sector (Evans, 2008: p. 65). The article begins with an exploration of cultural mapping within cultural policy, which explores the context for the growth in this area of activity, and why this kind of activity appeals to policy makers and organisations. It then goes on to examine four cultural mapping exercises which have been undertaken in recent years in the UK. These studies have been chosen because although they all focus the mapping of cultural assets within a specific geographic area, they differ to one degree or another in purpose, context, definition, geographic scale and methodology. They illustrate the narrow range of approaches deployed in the cultural mapping field in the UK, and as such provide a useful means of critically reviewing their limits as well as highlighting the issues and challenges faced by cultural cartography in practice. The article concludes by considering the type of mapping research that is “allowed” within the discursive confines of consultancy based cultural policy research.  相似文献
