Power Struggles,Regulation and Responsibility     

Sian Barber 《Media History》2018,24(1):99-114

This article explores the relationship between the British Board of Film Classification (BBFC) and government during the implementation of the Video Recordings Act (VRA). It considers the public Parliamentary debates about the VRA, and places them alongside private correspondence between the Home Office and the BBFC, and internal BBFC material from the recently catalogued James Ferman papers held at the BFI. As well as exploring the introduction of the VRA, this article also aims to briefly consider its implications for the BBFC, how they set about interpreting and implementing its stringent recommendations and how this impacted upon the organisational working practices of the Board. While the VRA was without doubt one of the most significant pieces of legislation within the history of film regulation in Britain, the time is ripe for its reappraisal and with it a re-evaluation of the role played by the BBFC in securing statutory regulatory powers.  相似文献

ABSTRACT

Soccer players are required to have well-developed physical, technical and cognitive abilities. The present systematic review, adhering to Preferred Reporting Items for Systematic reviews and Meta-Analysis guidelines, examined the effects of cognitive training strategies on motor and positive psychological skills development in soccer performance and identified the potential moderators of the “cognitive training–soccer performance” relationship. Thirteen databases were systematically searched using keywords related to psychological or cognitive training in soccer players. The review is based on 18 studies, employing 584 soccer players aged 7–39 years. Cognitive strategies, particularly imagery, appear to improve sports performance in soccer players. Regarding imagery, the combination of two different types of cognitive imagery training (i.e., cognitive general and cognitive specific) has a positive influence on soccer performance during training, whereas motivational imagery (i.e., motivational general-arousal, motivational general-mastery and motivational specific) enhance competition performance. Younger soccer players employ cognitive general and cognitive specific imagery techniques to a greater extent than older soccer players. Combined cognitive training strategies were more beneficial than a single cognitive strategy relative to motor skills enhancement in elite (particularly midfielders) and amateur (i.e., when practising complex and specific soccer skills in precompetitive period) soccer players. In conclusion, it appears that there are differences in cognitive/psychological training interventions, and their efficacy, according to whether they are directed towards training or competition, and the age, standard and playing position of the players.  相似文献   

Accelerometer data requirements for reliable estimation of habitual physical activity and sedentary time of children during the early years - a worked example following a stepped approach

This study presents a worked example of a stepped process to reliably estimate the habitual physical activity and sedentary time of a sample of young children. A total of 299 children (2.9 ± 0.6 years) were recruited. Outcome variables were daily minutes of total physical activity, sedentary time, moderate to vigorous physical activity and proportional values of each variable. In total, 282 (94%) provided 3 h of accelerometer data on ≥1 day and were included in a 6-step process: Step-1: determine minimum wear-time; Step-2: process 7-day-data; Step-3: determine the inclusion of a weekend day; Step-4: examine day-to-day variability; Step-5: calculate single day intraclass correlation (ICC) (2,1); Step-6: calculate number of days required to reach reliability. Following the process the results were, Step-1: 6 h was estimated as minimum wear-time of a standard day. Step-2: 98 (32%) children had ≥6 h wear on 7 days. Step-3: no differences were found between weekdays and weekend days (P ≥ 0.05). Step-4: no differences were found between day-to-day variability (P ≥ 0.05). Step-5: single day ICC’s (2,1) ranged from 0.48 (total physical activity and sedentary time) to 0.53 (proportion of moderate to vigorous physical activity). Step-6: to reach reliability (ICC = 0.7), 3 days were required for all outcomes. In conclusion following a 7 day wear protocol, ≥6 h on any 3 days was found to have acceptable reliability. The stepped-process offers researchers a method to derive sample-specific wear-time criterion.  相似文献   

An Exploration of the Relationship Among Teacher Efficacy,Collective Teacher Efficacy,and Goal Consensus   总被引：2，自引：0，他引：2  

Kurz  Terri Barber  Knight  Stephanie L. 《Learning Environments Research》2004,7(2):111-128

This study explored the relationships among individual teacher efficacy, collective teacher efficacy, and goal consensus/vision. Participants included 113 teachers of a high school located in the southwestern USA. During a teacher inservice meeting, teachers completed three surveys that measured the variables under study. Correlational and regression analyses were performed to examine the relationships among individual teacher efficacy, collective teacher efficacy, and goal consensus/vision. Collective teacher efficacy was found to be correlated with all of the other variables examined, but was most highly correlated with goal consensus/vision. Individual teacher efficacy, while related to collective teacher efficacy, was not found to be related to goal consensus/vision. Findings from this study suggest that, because individual teacher efficacy, collective teacher efficacy and goal consensus/vision are related, changing one could have an impact on the others. This revised version was published online in July 2006 with corrections to the Cover Date.  相似文献

The effects of anxiety and strategic planning on visual search behaviour     

Moran A  Byrne A  McGlade N 《Journal of sports sciences》2002,20(3):225-236

The past decade has witnessed increased interest in the visual search behaviour of athletes. Little is known, however, about the relationship between anxiety and eye movements in sport performers or about the extent to which athletes' planned and actual visual search strategies correspond. To address these issues, we conducted two studies. In Study 1, eight expert female gymnasts were presented with three digital slides of a model performing a skill that is known to be anxiety-provoking in this sport--namely, the 'back flip' on the beam. By varying the height of the beam and the presence or absence of safety mats, the slides differed in the amount of anxiety that they elicited vicariously in the viewer. In the study, the gymnasts were asked to imagine themselves in the position of the depicted model and to describe the anxiety that they felt. As they viewed the slides, their eye movements were recorded. As predicted, anxiety was associated with an increase in the number of fixations to peripheral areas. In addition, the more 'threatening' slides elicited significantly more fixations than the less feared images. In Study 2, the plans of 15 equestrian performers (5 expert, 5 intermediate and 5 novice) were elicited as they engaged in a virtual 'walk' around a computerized show-jumping course. Contrary to expectations, the congruence between intended and actual search behaviour was not significantly greater for expert riders than for the less skilled groups. Also, the fact that the top riders allocated more fixations to slides than the less skilled performers challenged the prediction that expertise would be associated with economy of visual search. Finally, as expected, the expert riders were significantly less dependent on the overall 'course plan' than the intermediate and novice equestrian performers when inspecting the fences.  相似文献

Development of letter position processing: effects of age and orthographic transparency     

Maria Ktori  Nicola J. Pitchford 《Journal of Research in Reading》2009,32(2):180-198

This study investigated the relative extent to which developing readers (6‐ and 9‐year‐olds) of English (deep) or Greek (transparent) orthography exhibit serial and exterior letter effects in letter position encoding. Participants were given a visual search task that required detection of a pre‐specified target letter within a random five‐letter string. Stimuli comprised letters either specific to English or Greek, or shared by both orthographies. For native letters, all readers showed significant initial‐letter facilitation. In contrast, final‐letter facilitation was shown only by English children. Furthermore, Greek 9‐year‐olds showed significantly more left‐to‐right facilitation than English 9‐year‐olds. These results suggest that letter position encoding is adaptive to the nature of the orthography acquired during reading development.  相似文献
