The effect of towing a range of relative resistances on sprint performance

The aim of this study was to compare sprint performance over 10 and 20?m when participants ran while towing resistances, weighing between 0 and 30% of body mass. The sample of 33 participants consisted of male rugby and soccer players (age 21.1?±?1.8 years, body mass 83.6?±?13.1?kg, height 1.82?±?0.1?m; mean?±?s). Each participant performed two sets of seven sprints over 20?m using a Latin rectangular design. The times were recorded at 10 and 20?m using electronic speed gates. The sprints of 13 players were video-recorded to allow calculation of stride length and frequency. For both sprints, a quadratic relationship was observed between sprint time and resistance as sprint time increased from 2.94?s to 3.80?s from 0 to 30% resistance. This relationship was statistically significant but considered not to be meaningful for performance because, over the range of resistances used in this study, the quadratic model was never more than 1% (in terms of sprint time) from the linear model. As resistance increased, the stride length shortened, with mean values of 1.63?±?0.13?m at 0% body mass and 1.33?±?0.13?m at 30% of body mass. There was no significant change in stride frequency with increasing resistance. The results show that in general there is an increase in sprint time with an increase in resistance. No particular resistance in the range tested (0?–?30%) can be recommended for practice.     

The Birth of the Sports Press in Spain Within the Regenerationist Context of the Late Nineteenth Century

This study tackles the birth and development of the sports press in Spain from 1865 to 1899, linked to the need of a bourgeois society to emulate the English lifestyle, characterised by the sports craze. The sports press in Spain fitted extremely well in the late nineteenth century, encouraged by the Regenerationist movement. This is clear by the growth in number of sports publications, by the promotion of physical culture by Regenerationism and by the use of such publications to spread Regenerationism's approach to sport. Both primary and secondary sources were used in the research process. With regard to primary sources, archives containing specific documentation on the origins and early years of the sports press in Spain were examined. A total of 85 sports publications were counted in 18 different towns, but mostly concentrated in Madrid (28) and Barcelona (24). The most widely represented sports in these were cycling (25) and hunting (18). Among those publications that were not specific to one sport, 13 titles included the English-language term ‘sport’, and only two incorporated the newly coined Spanish word, ‘deporte’. Los Deportes (1897–1910) is the most important publication of this period and the foundation stone of modern sports journalism in Spain.     

Challenges to Cognitive Bases for an Especial Motor Skill at the Regulation Baseball Pitching Distance

We tested expert baseball pitchers for evidence of especial skills at the regulation pitching distance. Seven college pitchers threw indoors to a target placed at 60.5 feet (18.44 m) and four closer and four further distances away. Accuracy at the regulation distance was significantly better than predicted by regression on the nonregulation distances (p < .02), indicating an especial skill effect emerged despite the absence of normal contextual cues. Self-efficacy data failed to support confidence as a mediating factor in especial skill effect. We concluded that cognitive theories fail to fully account for the patterns of observed data, and therefore theoretical explanations of the especial skills must address noncognitive aspects of motor learning and control.     

Exploring the relationship between school discipline referrals and delinquency

There is a growing concern about violent and destructive behaviors of youth that require intervention by juvenile justice and youth‐serving agencies. This concern has led many to conclude that schools and community agencies must increase efforts to prevent juvenile delinquency and to provide programs that will facilitate rehabilitation, education, and vocational training for youth already involved. A clear understanding of the nature and range of behaviors that result in juvenile crime is needed in order to develop programs and interventions that can be expected to lead to beneficial changes for youth and for society as a whole. The purpose of this article is to describe the relationship between school behaviors and youth characteristics in school (e.g., discipline referrals, teacher nominations, nomothetic ratings) and referrals to juvenile authorities (e.g., illegal behaviors). We describe a strategy of using teacher nominations, school discipline referrals, and community arrest data to predict delinquent and violent behavior in youth. We outline data from a group of socially maladjusted middle school youth to illustrate the relationship between the two data sources and recommendations for identification and treatment of youth at risk for delinquency and antisocial behavior. © 2001 John Wiley & Sons, Inc.     

A Mixed Methods Examination of Gender Disparity in High Schools Implementing Advancement Via Individual Determination (AVID)

This mixed-methods research study offers insights and explanations into gender imbalance in the college readiness program, Advancement Via Individual Determination (AVID). Over 200 schools that have been implementing AVID for more than 4 years across the United States participated in this study. Three years of archived historical data pertaining to school demographic information and AVID certification information was accessed and analyzed to examine recruitment and retention of male and female students over time, as well as student enrollment in rigorous curriculum. Our research indicated that at the high school level, gender disparity became most apparent in the 11th and 12th grades. Results indicated that schools that struggled to recruit and retain boys continued to enroll AVID students, both boys and girls, into rigorous advanced placement curriculum at comparable rates as schools that did not struggle to recruit and retain boys in the program. This indicates that once in AVID, boys and girls are provided equal access to rigor; however, recruiting and retaining boys in AVID continues to be a challenge for AVID schools. Research participants indicated that academic identity, peer and family support, leadership and mentoring opportunities and male role models influence male participation in AVID.     

The multilevel impact of transformational leadership on teacher commitment: Cognitive and motivational pathways

A growing body of research indicates that transformational leadership affects teachers’ commitment to their school. The present study aims to investigate the processes explaining this effect at the organisational level. Using a sample of 660 teachers within 50 primary French‐speaking Belgian schools, the authors test a model hypothesising that the impact of the school principal's transformational leadership (as an organisational‐level construct) on teacher commitment to school is mediated by school culture strength (cognitive pathway) and teacher collective efficacy beliefs (motivational pathway). Results of multilevel analyses largely support the theoretical model, but show that schools have a limited impact on teacher commitment.     

The nature of teacher engagement at an online high school

Little research has examined the critical components of successful K‐12 online schools, due in part to the theoretical focus of current frameworks on higher education rather than characteristics of K‐12 online learners and environments. Using K‐12 online research, this paper examined teaching presence as explained by the Community of Inquiry framework and identified additional teacher roles that needed stronger emphasis. We termed the new construct teacher engagement. Teacher engagement was shown to be helpful in describing and identifying effective teacher practices at the Open High School of Utah (OHSU), a successful online charter school. Through a series of 22 interviews with over half of the OHSU faculty, it was found that teachers worked to improve student outcomes by (1) designing and organizing learning activities, (2) facilitating discourse with students and parents, (3) providing students with one‐on‐one instruction, (4) nurturing a safe and caring learning environment, (5) motivating students to engage in learning activities and (6) closely monitoring student behavior and learning. These six elements describe the core of teacher engagement.     

Educational quasi-markets,school effectiveness and social inequalities

Over the past few decades, the figure of the market has clearly made its way into the field of education. For some authors, it represents an alternative to regulation by the public authorities, a different form of co-ordination which is better able to meet the objectives of the education systems. Through a secondary analysis of the PISA 2006 database, we test this hypothesis, as well as an alternative one which suggests that the quasi-market, rather than being linked positively to effectiveness of the education systems, would be associated with the students’ achievement dependence on their socio-economic and cultural background and on the social composition of the school they are enrolled in. Our findings suggest that the quasi-market regulation (school autonomy and competition for student recruitment) (1) is not linked to effectiveness and (2) tends to be associated with a stronger link between schools’ social composition and student achievement.     

Measuring Attitudinal Change in Mathematics and English Over the 1st Year of Junior High School: A Multidimensional Analysis

Changes in student self- and task evaluations, subjective valuation, and achievement behavior in mathematics and English over the 1st year of junior high form the basis of this study. The transition to junior high has been found to negatively affect students' self-concept and subjective valuation in mathematics and English, but previous research has not addressed changes in task evaluations and achievement behaviors. Gender and level of academic achievement effects are also relevant to the nature of changes in student attitudes. The participants (N =400) were from 3 coeducational Australian government schools in metropolitan Sydney of comparable socioeconomic status. When changes in perceptions occurred, they were negative, and gender differences favored boys in mathematics and girls in English. However, the nature and extent of change was dependent on school and level of achievement.     

Letters to the editor

This study examines editorial photography in nine major erotica magazines to determine how pictures vary as a function of the social class, gender and sexual preference of the intended readership. The analysis reveals that upwardly‐mobile, heterosexual men are treated to idealized images, whereas working‐class, heterosexual men are presented with more mundane yet highly‐sexualized images. Heterosexual women are provided with photographs of nude males in a low‐sexual context. Magazines for homosexual men present images, except for gender, very similar to those created for upwardly‐mobile, heterosexual men. These patterns are discussed from a functionalist perspective to show how erotica magazines contribute to social‐order maintenance.
