Racial tensions continue in 21st-century United States through the communication of racial microaggressions. We are interested in the communication of racial microaggressions directed towards West African immigrants by people with whom they expected to be allied, African Americans. Sixteen people who identified as West African immigrants were interviewed about communication struggles with African Americans in this qualitative, interpretive analysis. Owen’s thematic analysis was employed to analyze interview data. Results suggest the communicative impact of racial microaggressions on recipients is far-reaching and consequential. Narratives illustrate microaggressive communication occurs daily through invalidating, dismissive lines of questioning as well as targeted name calling and pejorative dialogue. 相似文献

Objectives: To improve well-being and performance indicators in a group of Australian Football League (AFL) players via a six-week sleep optimisation programme. Design: Prospective intervention study following observations suggestive of reduced sleep and excessive daytime sleepiness in an AFL group. Methods: Athletes from the Adelaide Football Club were invited to participate if they had played AFL senior-level football for 1–5 years, or if they had excessive daytime sleepiness (Epworth Sleepiness Scale [ESS] >10), measured via ESS. An initial education session explained normal sleep needs, and how to achieve increased sleep duration and quality. Participants (n?=?25) received ongoing feedback on their sleep, and a mid-programme education and feedback session. Sleep duration, quality and related outcomes were measured during week one and at the conclusion of the six-week intervention period using sleep diaries, actigraphy, ESS, Pittsburgh Sleep Quality Index, Profile of Mood States, Training Distress Scale, Perceived Stress Scale and the Psychomotor Vigilance Task. Results: Sleep diaries demonstrated an increase in total sleep time of approximately 20?min (498.8?±?53.8 to 518.7?±?34.3; p?<?.05) and a 2% increase in sleep efficiency (p?<?0.05). There was a corresponding increase in vigour (p?<?0.001) and decrease in fatigue (p?<?0.05). Conclusions: Improvements in measures of sleep efficiency, fatigue and vigour indicate that a sleep optimisation programme may improve athletes’ well-being. More research is required into the effects of sleep optimisation on athletic performance. 相似文献

This article outlines BPRS funded investigations into my own school's and other establishments' practices and processes within data analysis, needs identification and tracking of children's academic progress. It describes the evaluation of my school's then current practices and policies and the use of questionnaires and semi-structured interviews with my own staff, and assessment coordinators and senior leaders within exemplar schools. As well as outlining the main findings of my research this article assesses the introduction of new models of assessment for my own staff and pupils. This article also highlights how my research developed and the way my research process changed as it continued. 相似文献

This study aimed to (1) evaluate the effect of hand shaking during recovery phases of intermittent testing on the time–force characteristics of performance and muscle oxygenation, and (2) assess inter-individual variability in the time to achieve the target force during intermittent testing in rock climbers. Twenty-two participants undertook three finger flexor endurance tests at 60% of their maximal voluntary contraction until failure. Performances of a sustained contraction and two intermittent contractions, each with different recovery strategies, were analysed by time–force parameters and near-infrared spectroscopy. Recovery with shaking of the forearm beside the body led to a significantly greater intermittent test time (↑ 22%, P?.05), force–time integral (↑ 28%, P?.05) and faster muscle re-oxygenation (↑ 32%, P?.05), when compared to the hand over hold condition. Further, the ratio of intermittent to continuous test time distinguished specific aerobic muscular adaptations among sport climbers (2.02), boulderers (1.74) and lower grade climbers (1.25). Lower grade climbers and boulderers produced shorter duration contractions due to the slower development of target force during the intermittent test, indicating worse kinaesthetic differentiation. Both the type of recovery and climbing discipline determined muscle re-oxygenation and intermittent performance in rock climbers. 相似文献

AbstractMentoring undergraduate students in research is both rewarding and challenging. In this paper we present how we established a summer Research Experience for Undergraduates (REU) program in the mathematical sciences at Michigan State University. A goal of our REU is to include students who are at an early stage of their study of mathematics. We share our experiences in recruiting students, designing research projects, and mentoring our participants. We discuss the challenges we faced and the solutions we found while working with a diverse group of undergraduate students from across the nation. 相似文献

The empirical study explores children's perceptions of the family and family membership. 300 four‐, six‐ and eight‐year‐old children were interviewed with a semi‐structured ‘Family Concept Interview’. Interview strategies and research findings are presented and discussed. Establishing field entry rituals and determining appropriate modes and levels of discourse are important factors for creating an interview situation in which children are continuously attentive and motivated. Findings indicate that children do have a generalised and complex image of the family. The majority construct relatively large families with two or more children; over half the children include grandparents (father and mother)’, but one‐parent‐households are also accepted as ‘a family’, regardless of the child's own family situation. ‘Common residence’ is an important but not a necessary criterion for family membership. The findings show significant age differences concerning some aspects of children's family concepts. 相似文献
