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 (M_age = 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   

Fifty Years of Super Bowl Commercials,Thirty-Two Years of Spectacular Consumption     

Matthew P. McAllister  Elysia Galindo-Ramirez 《国际体育史杂志》2017,34(1-2):46-64

Abstract

This article will explore the role and visibility of advertising during the Super Bowl over the years as a model for strategies of modern advertising and the resulting commercialization of US society. It uses the concepts of ‘spectacular consumption’ derived from Guy Debord and the ‘commodity audience’ from Dallas Smythe to frame the commercials’ cultural transformation and influence. The spectacular nature of Super Bowl commercials and the special commodity worth of its audience were not present in the early days of the event, but gained momentum with Super Bowl XVII and its airing of Apple’s ‘1984’ commercial that became mythologized in the advertising industry. After 1984, both the rising inflation-adjusted CPM (‘cost-per-thousand’) and the increased media coverage indicate an increased spectacularization. This also manifested in such phenomena as the influential, decades-long Doritos user-generated content contests and the Greatest Super Bowl Commercials TV specials, and was a forerunner of such post-millennial advertising strategies as branded entertainment and content marketing, all designed to integrate advertising as a legitimate form of entertainment culture and prevent the avoidance of advertising by audiences.  相似文献

One step antibody-mediated isolation and patterning of multiple cell types in microfluidic devices

Cell-cell interactions play a key role in regeneration, differentiation, and basic tissue function taking place under physiological shear forces. However, current solutions to mimic such interactions by micro-patterning cells within microfluidic devices have low resolution, high fabrication complexity, and are limited to one or two cell types. Here, we present a microfluidic platform capable of laminar patterning of any biotin-labeled peptide using streptavidin-based surface chemistry. The design permits the generation of arbitrary cell patterns from heterogeneous mixtures in microfluidic devices. We demonstrate the robust co-patterning of α-CD24, α-ASGPR-1, and α-Tie2 antibodies for rapid isolation and co-patterning of mixtures of hepatocytes and endothelial cells. In addition to one-step isolation and patterning, our design permits step-wise patterning of multiple cell types and empty spaces to create complex cellular geometries in vitro. In conclusion, we developed a microfluidic device that permits the generation of perfusable tissue-like patterns in microfluidic devices by directly injecting complex cell mixtures such as differentiated stem cells or tissue digests with minimal sample preparation.  相似文献

CURRENT AND FUTURE SCHOOL PSYCHOLOGISTS’ PREPAREDNESS TO WORK WITH LGBT STUDENTS: ROLE OF EDUCATION AND GAY‐STRAIGHT ALLIANCES     

Prerna G. Arora  Jennifer Kelly  Thalia R. Goldstein 《Psychology in the schools》2016,53(7):722-735

This study sought to assess current and future school psychologists’ attitudes toward and preparedness to address the needs of lesbian, gay, bisexual, and transgender (LGBT) students in schools. Two‐hundred seventy‐nine school psychologists (n = 162, 58%) and school psychology graduate students (n = 117, 42%) were included in the study. Participants completed measures of attitudes toward LGBT students, preparedness to address the needs of LGBT youth, and social desirability. For both school psychologists and graduate students, increased education was associated with improved attitudes and increased preparedness to treat LGBT youth. For school psychologists, presence of a gay‐straight alliance was associated with increased knowledge about LGBT youth, as well as higher ratings of preparedness to treat LGBT youth; the same associations did not hold true for the graduate students. These findings have implications for the training and practice of school psychologists in addressing the needs of LGBT youth in schools.  相似文献
