This paper reports a thorough investigation of reading habits and activities which may require skills used in prose recall tasks as they occur in the everyday lives of adults. Over the space of five weeks, fifty‐four participants (18 young, aged 18‐32; 18 middle, aged 40‐54; 18 older, aged over 62) kept structured diaries in which they indicated how they spent their time, as well as the specific materials they had read and how long they had spent reading each item. Analyses were performed on each of 23 reading variables and 20 activity variables. Part I of this paper considers whether there were age and vocabulary differences in activities. Results indicate that while such differences exist, primarily in the amount of time spent reading, everyday activities and reading habits were also related to the requirements of daily life‐‐school, employment, retirement. Part II uses a cluster analysis of the data to demonstrate that the patterning of everyday activities was influenced more by current schooling and career factors than by the age and vocabulary level of the participants. Part II also considers the ecological validity of prose recall studies by examining the frequency of activities similar to laboratory‐style prose recall tasks and finds that such activities have a very low incidence in the everyday lives of adults. 相似文献

The aim of this article is to explore the experiences of female elite-level Norwegian coaches in football. More precisely, we wanted to find out the meaning of gender for these coaches’ football experiences. The results presented are based on five in-depth interviews with female elite-level coaches between 36 and 50 years of age. A feminist cultural and a gender perspective are used to understand and discuss the findings. As shown in other studies, the culture of football in Norway is very gendered. This has an impact on the female football coaches’ experiences, both in relation to how they perceive their own role, their coach education and with respect to their self-confidence and how they look upon their own chances in the job market. As a group, they represent a form of pariah femininity, and very little resistance femininity and a liberal feminist perspective, i.e. equality on the men’s premises. 相似文献

This cross-sectional study analysed the association of sedentary behaviour (SB) and standing with waist circumference. Finnish adults aged 30-75 years from a sub-sample of population-based Health 2011 Study used a hip-worn tri-axial accelerometer (Hookie AM20, Traxmeet, Ltd, Espoo, Finland) for seven days. Those 1405 participants (57% women) who used accelerometer at least four days, minimum of 10 hours/day, were included. SB and standing were analysed in 6s epochs using validated algorithm. Daily total time, daily number and accumulated time from bouts (30s–5min,30s–10min,30s–15min,30s 30min,>5min,>10min,>15min, >30min) as well as daily number of sit-to-stand transitions were determined. Waist circumference (cm) was measured in standardized way. Participants’ mean age was 52 years (SD 12.2). Mean waist circumference was 97cm (SD 12.3) in men and 87cm (SD 12.7) in women. According to multivariable stepwise linear regression analysis, sit-to-stand transitions [standardised regression coefficient (β)= -0.14, 95%CI -0.20 to -0.09], standing bouts of 30s–5min (β= -0.21, 95%CI -0.26 to -0.15) and number of 30s-30min SB bouts (β=0.12, 95%CI 0.06 to 0.17) were most strongly associated with waist circumference. Besides assessing total SB time, future studies should assess also different bout lengths of SB and sit-to-stand transitions and standing times should be assessed separately. 相似文献

Drawing on the perspectives of youth involved in breaking, also known as breakdance, the aim of this article is to explore how their experiences contribute to the doing, redoing and undoing of gender. The negotiation of gender is highlighted through the female breakers’ experiences in a male-dominated culture. The analysis is based on fieldwork and qualitative interviews with young breakers in Norway. The results show that the female breakers challenged the perception of masculinity and femininity as they extended their practice of gender. Their desire to disprove the gendered expectations of female breakers resulted in a mixing of masculinity and femininity. Accordingly, the gender regime among the breakers was simultaneously re-constructed and challenged. We argue that both male and female breakers challenge normative perceptions of doing gender. Consequently, breaking has the capacity to dismantle the gender binary, and to redo and undo the gender order. 相似文献

Although the importance of high motivation to engage in deliberate practice has been acknowledged, no research has directly tested this hypothesis. Therefore, the present study examined this relation in adolescent elite chess players by means of a questionnaire. In addition, to provide an explanation for dropout among promising chess players, differences in motivation between persistent and dropout chess players were analyzed. Competitiveness and the will to excel proved to be predictors of investments in deliberate practice. Moreover, achievement motivation and chess-specific motivation differed to a certain extent between persisters and dropouts. Our results suggest that motivation to engage in deliberate practice not only contains elements of the will to improve performance, but also of the will to attain exceptional levels of performance. 相似文献

This article explores the implementation of special collections interlibrary loan policies and procedures at the University of South Florida (USF), focusing particularly on the development of policies related to physically loaning published materials, and traces the development of these policies through a pilot project to routinized implementation. Particular attention is paid to developing mutually beneficial workflows between special collections and interlibrary loan departments, creating transparent policies for the criteria under which requests are or are not filled, and technical considerations for implementing special collections loans. Through this case study, we highlight the potential for collaboration in the fulfillment of special deliveries. 相似文献

We evaluated the efficacy of an in-field gait retraining programme using mobile biofeedback to reduce cumulative and peak tibiofemoral loads during running. Thirty runners were randomised to either a retraining group or control group. Retrainers were asked to increase their step rate by 7.5% over preferred in response to real-time feedback provided by a wrist mounted running computer for 8 routine in-field runs. An inverse dynamics driven musculoskeletal model estimated total and medial tibiofemoral joint compartment contact forces. Peak and impulse per step total tibiofemoral contact forces were immediately reduced by 7.6% and 10.6%, respectively (P < 0.001). Similarly, medial tibiofemoral compartment peak and impulse per step tibiofemoral contact forces were reduced by 8.2% and 10.6%, respectively (P < 0.001). Interestingly, no changes were found in knee adduction moment measures. Post gait retraining, reductions in medial tibiofemoral compartment peak and impulse per step tibiofemoral contact force were still present (P < 0.01). At the 1-month post-retraining follow-up, these reductions remained (P < 0.05). With these per stance reductions in tibiofemoral contact forces in mind, cumulative tibiofemoral contact forces did not change due to the estimated increase in number of steps to run 1 km. 相似文献
