Relation between reading problems and internalizing behavior in school for preadolescent children from economically disadvantaged families     

Ackerman BP  Izard CE  Kobak R  Brown ED  Smith C 《Child development》2007,78(2):581-596

This longitudinal study of 105 economically disadvantaged children examined the relation between reading problems and internalizing behavior in 3rd- and 5th-grade assessments (8- to 12-year olds). The variable-centered results showed that reading problems predicted change in internalizing behavior in the context of child and family predictors. The person-centered results showed that children with reading problems in both grades had higher internalizing scores in 5th grade but not in 3rd grade than children with reading problems in 3rd grade or no problems. Child-reported negative emotion experiences varied similarly across grade. The results tie reading problems to emotional distress in school and support conclusions about the direction of effects and the internalization of academic difficulty for disadvantaged children.  相似文献   

本期话题：多元语境中的话语场——文艺复兴时期关于亚里士多德《修辞学》的论争：传播理论的跨文化解读     

劳伦斯·葛林美  陈汝东 《福建师范大学学报(哲学社会科学版)》2007,(2):47-53

本演讲探讨了欧洲早期艺复兴期间（大约1350—1700）为解读亚里士多德的（修辞学）中的论述所做出的努力,讨论了欧洲的注释在理解亚里士多德的（修辞学〉中所遇到的困难,关注了当时学意料之外的某些论争,并力图阐释引起这些论争的原因。作认为,人们力图阐释关于一种化的论述并力图从另一种化的需求和兴趣来解读这种论述的努力对中美两国具有重要意义,这些阐释所可能引发的结果也具有积极意义。作的这种解读对当今世界——对中国和“西方”国家富有更为广泛的意义——因为他在试图解读产生于一种化而被转译到另一种化的修辞学和传播学理论。作指出,在欧洲艺复兴时期,人们相信修辞学和社会很大程度上是一回事。修辞学能够使人们避免暴力、摆脱兽性,使许多不同人的思想统一起来,促成一种包容各种矛盾的和谐社会。修辞学使我们变得明。[第一段]  相似文献   

Decision-making skills and deliberate practice in elite association football referees     

MacMahon C  Helsen WF  Starkes JL  Weston M 《Journal of sports sciences》2007,25(1):65-78

We examined sport expertise as a function of role. In study 1, referees were better than players in a video-based decision-making task. This provides evidence that there are role-specific skills within one domain or sport. In study 2, we examined the training activities that could be influential in the development of skills in sports officials. Elite association football (soccer) referees retrospectively reported time spent in and perceptions of training activities for three periods: their first year of formal refereeing, 1998 (before formal training programmes were available), and the current year (2003). This allowed us to examine an area of skill with a limited culture of practice, where performance simulations with direct feedback are usually not feasible. The results showed that referees specialize early and, as they develop, they engage in greater volumes and types of training. Competitive match refereeing is considered a relevant activity for skill acquisition that does not fit Ericsson and colleagues' (1993) original definition of deliberate practice. Our findings indicate that actual performance is a significant activity for skill acquisition and refinement.  相似文献   

Export restrictions,tax incentives and the national artistic patrimony     

Clare McAndrew  John O'Hagan 《Cultural Trends》2000,10(37):41-63

This paper analyses the main forms of government intervention used in the UK to protect the national artistic patrimony. It examines the two most common policy measures used in the art market ‐ export regulation and tax incentives ‐ and reports their use over an eight‐year period from 1990 to 1998. It also reviews the UK's collective obligations to patrimony internationally and specifically as a member of the European Union. This is the first time that these related topics have been considered as a whole.  相似文献   

Combined individual scrummaging kinetics and muscular power predict competitive team scrum success     

Andrew Green  Chloe Dafkin  Samantha Kerr  Warrick McKinon 《European Journal of Sport Science》2017,17(8):994-1003

Scrummaging is a major component of Rugby Union gameplay. Successful scrummaging is dependent on the coordination of the forward players and the strength of the eight individuals. The study aim was to determine whether individual scrummaging kinetics and other candidate factors associated with scrummaging performance discriminate team scrum performances. Sixteen club-level forwards (stature: 1.80?±?0.1?m; mass: 99.0?±?18.2?kg) were initially divided into two scrummaging packs. A total of 10 various scrum permutations were tested, where players were randomly swapped between the two packs. Winning scrums were determined by two observers on opposite sides of the scrum. Fatigue (100?mm visual analogue scale (VAS)) and scrummaging effort (6–20 rating of perceived exertion (RPE)) were assessed following each scrum contest. Individual scrummaging kinetics were acquired through an instrumented scrum ergometer and muscular power indicated through vertical jump heights. Student’s t-tests were used to differentiate between winning and losing scrum packs. VAS and RPE were assessed using repeated measures ANOVAs. Winning scrum packs had significantly larger combined force magnitudes (p?<?.002), regardless of the player contribution calculations. Additionally, winning packs had less individual movement (p?=?.033) and higher combined vertical jump heights (p?<?.001) but were not significantly heavier (p?=?.759) than losing scrum packs. While perceived VAS and RPE values progressively increased (p?<?.001), no differences in the individual scrum magnitudes were observed between the 1st and 10th scrum (p?=?.418). The results indicated that the combination of individual forces, variation in movement and factors related to scrummaging performance, such as vertical jump height, were associated with team scrummaging success.  相似文献   

Contextual influences on baseball ball-strike decisions in umpires, players, and controls     

MacMahon C  Starkes JL 《Journal of sports sciences》2008,26(7):751-760

Baseball umpires, players, and control participants with no baseball experience were asked to call balls and strikes for video clips. In a basic judgement task, umpires and players were significantly better at calling pitches than controls. In a direct information task, borderline pitches were presented following clips of definite balls and definite strikes. Participants called target pitches closer to the strike end of the scale when viewed after definite balls than when they followed definite strikes. Similarly, when borderline pitches were shown in different pitch counts, participants called pitches more towards the strike end of the scale when there were three balls in the count (3-0, 3-2). These findings indicate that the standard for evaluation changes based on the context in which stimuli are processed. Moreover, the strength of the contextual factors is illustrated in that the effects were shown in observers with and without experience in the task. Overall, however, umpires had a greater tendency to call strikes, indicating that they may use a norm of "hastening the game".  相似文献   

Seasonal progression and variability of repeat-effort line-drill performance in elite junior basketball players     

Montgomery PG  Pyne DB  Hopkins WG  Minahan CL 《Journal of sports sciences》2008,26(5):543-550

To determine gender differences, positional differences, and patterns of change in the performance of the basketball line-drill test, 93 male (mean age 16.8 years, s = 1.1) and 95 female (mean age 16.5 years, s = 1.0) basketball players undertook 516 line-drill tests over a 5-year period. Log-transformed performance times were analysed using a mixed model that included quadratic within-participant fixed effects for time in the season and time in the programme. Changes and differences were standardized for interpretation of magnitudes. Mean performance times were 28.0 s (s = 1.3) for males and 30.4 s (s = 1.3) for females. The mean pattern of change in performance within a season differed substantially between the sexes and playing positions: male guards and female centres showed moderate to very large improvements mid-season of 1.1% and 3.5% respectively (90% confidence limits +/-2.1% and +/-3.0%), while female guards and male forwards showed large to very large decrements of -1.6% (+/-2.6%) and -2.4% (+/-2.0%). Over 3 years, males improved performance across all three playing positions by 1.4% (+/-1.3%) and females by 2.9% (+/-1.4%). Males improved performance by 0.2% (+/-0.5%) per year, whereas the performance of females deteriorated by 0.6% (+/-0.4%) per year. The differing patterns of performance change presumably reflect variations in training and competition loads, with short-term fluctuations in performance being managed to promote longer-term improvements.  相似文献

The economic contribution of historic parks,gardens and designed landscapes: A review of existing data and research and recommendations for future research     

Clare Askwith Consultant 《Cultural Trends》1999,9(35):27-79

Despite an increased awareness over the last few years of the unique historic, cultural and artistic value of historic designed landscapes, parks and gardens, few hard facts and figures appeared to be available relating to their undoubted economic contribution. With this in mind, the Garden History Society announced its intention to host a conference in late 2001 on the economic contribution of historic parks and gardens and, with support from the Heritage Lottery Fund, commissioned the following study.

The study's objective was to review and analyse existing research and data on the economic contribution of historic parks and gardens, and to make recommendations for a range of research projects to fill any gaps identified.

The report first sets historic parks and gardens within the wider context of the ‘gardens and gardening’ market generally; it then deals with the economic impact of tourism, recreation and leisure at historic parks and gardens and then with the economic contribution of public parks with particular regard to the latter's role in promoting regeneration of the local area. The applicability of various non‐market valuation techniques is considered in relation to free‐entry parks and gardens. Finally, specific research recommendations are set out to cover stocktaking, the visitor attraction sector, local area regeneration and the valuation of non‐market sites.  相似文献
