Cytokine responses to resistance training in people with multiple sclerosis

Exercise for individuals with multiple sclerosis (MS) has been shown to improve cardiovascular function, increase strength and endurance, and reduce fatigue. The impact of exercise on immune function in the disease, however, remains mostly unexplored. Ten female MS patients participated in an 8 week programme of twice-weekly progressive resistance training, with pre- and post-training assessment of serum concentrations of cytokines IL-2, IL-4, IL-6, IL-10, CRP, TNF-alpha and IFN-gamma. After training, IL-4, IL-10, CRP and IFN-gamma showed statistically reduced resting concentrations in blood, while TNF-alpha showed non-significant reductions and IL-2 and IL-6 remained unchanged. These results suggest that progressive resistance training may have an impact on cytokine concentrations in individuals with MS and should be confirmed in studies with stronger statistical power. The impact of these changes on overall immune function in MS and on disease status and prognosis remains to be determined.     

Influence of starting position on finishing position in World Cup 500 m short track speed skating

Top short track speed skaters and their coaches have suspected that starting positions influence finishing positions, especially in the 500 m racing distance. The objective of this study was to examine systematically the influence of starting position on finishing position in 500 m short track speed skating. The data analysed included results from World Cup 500 m races ranging from the 1999-2000 season through to the end of the 2003-2004 season. All 500 m men's and women's races with four skaters starting and finishing (preliminaries, heats, quarter-finals, semi-finals and finals) were included in the data set. The association between starting position and finishing position was examined using Kendall's tau. Results show that for both sexes, there is a significant positive correlation between starting position and finishing position (P<0.001). This effect is generally more pronounced in semi-finals and finals than it is in preliminaries, heats and quarter-finals. Strategies to counter this inequity are proposed, drawing upon similar experiences in other sports.     

Maturity-associated variation in sport-specific skills of youth soccer players aged 13-15 years

The aim of this study was to estimate the contribution of experience, body size and maturity status to variation in sport-specific skills of adolescent soccer players. The participants were 69 players aged 13.2-15.1 years from three clubs that competed in the highest division for their age group. Height and body mass were measured and stage of pubic hair development was assessed at clinical examination. Years of experience in football was obtained at interview. Six football skill tests were administered: ball control with the body, ball control with the head, dribbling with a pass, dribbling speed, shooting accuracy and passing accuracy. Multiple linear regression analysis was used to estimate the relative contributions of age, stage of sexual maturity, height, body mass and years of formal training in soccer to the six skill tests. Age, experience, body size and stage of puberty contributed significantly but in different combinations to the variance in four of the six skill tests: dribbling with a pass (21%; age, stage of maturity), ball control with the head (14%; stage of maturity, height, body height x body mass interaction), ball control with the body (13%; stage of maturity, years of training) and shooting accuracy (8%; stage of maturity, height; borderline significance, P = 0.06). There were no significant predictors for the tests of dribbling speed and passing accuracy. In conclusion, age, experience, body size and stage of puberty contributed relatively little to variation in performance in four of the six soccer-specific skill tests in adolescent footballers aged 13-15 years.     

Philosophy in Schools: A Catholic School Perspective

This article builds on the recent Special Interest issue of this journal on ‘Philosophy for Children in Transition’ (2011) and the way that the debate about philosophy in schools has now shifted to whether or not it ought to be a compulsory part of the curriculum. This article puts the spotlight on Catholic schools in order to present a different argument in favour of introducing compulsory philosophy lessons into the curriculum. It is explained that in faith schools, such as Catholic ones, there is an additional need or imperative to have compulsory philosophy as part of the curriculum. This is because it serves as an effective way of avoiding the inherent dangers of confessional education, particularly the indoctrination challenge. It is argued that Catholic schools also have some intriguing theological reasons that can be used to justify the inclusion of compulsory philosophy in the school curriculum. It is proposed that when it comes to philosophy in schools there is a distinctive Catholic school perspective. As part of this it is explained why Catholic schools, perhaps more than others, need philosophy to be a compulsory part of the curriculum.     

Changes in Cooperation and Self-Other Differentiation during the Second Year

Cooperation in peer interaction emerges during the second half of the second year. A consideration of the skills and knowledge entailed in these early forms of cooperation suggests that young children's emerging ability to differentiate self from other as causal agents may relate to their ability to coordinate behavior with age mates toward a common goal. Children at 12, 18, 24, and 30 months were observed in same-age, same-sex dyads (8 dyads per age) while attempting to solve a simple cooperation problem. They were also individually administered an elicited imitation task used to index decentration, or self-other differentiation. No 12-month-old dyad could cooperate, 18-month-olds did so infrequently and apparently accidentally, whereas 24- and 30-month-olds were able to coordinate behavior with one another quickly and effectively. Children who were better able to accommodate their behavior to one another during cooperation also represented the agency of others at a more advanced, decentered level.     

The efficacy of directed studies courses as a form of undergraduate research experience: a comparison of instructor and student perspectives on course dynamics

Directed studies (DS) courses are widely touted for their ability to enhance research skills in undergraduate students—yet little is known about the dynamics, motivations, and perceived outcomes connected to these specific types of undergraduate research experiences. Building on earlier qualitative research, in this paper we report the results of a self-report survey designed to directly compare instructor and student perspectives on DS course dynamics at a small, liberal arts university. Samples of students who completed DS courses and instructors who supervised them completed a survey assessing their motives, perceived outcomes, and barriers encountered in their course work. Parallel wording of items in instructor and student surveys permitted comparison of perceptions of DS course dynamics. Results indicated that there were many similarities in how both groups approached DS courses but that there were also several important differences in motives and perceived outcomes pointing to the need for greater communication between instructors and students about their expectations for the course.     

Teacher and Student Attitudes to Affective Education: A European collaborative research project

This article reports on the outcomes of a comparative research project examining teacher and student attitudes to affective education across Europe. Affective education is defined as the aspect of the educational process that is concerned with the feelings, values, beliefs, attitudes and emotional well-being of learners. The article begins with a consideration of some of the conceptual issues in affective education and its diversity across Europe as a basis for stressing the relevance of cross-cultural comparisons. It then offers a general picture of the findings of the present research project, draws a number of tentative conclusions from this and ends with a reference to issues requiring further research in comparative work on affective education.     

Part-time academics’ perception of their role and academic development: a case study from Indonesia

ABSTRACT

Employing part-time and casual academics is now a widely accepted practice in higher education globally. We explored the issue of the identity of part-time academics in Indonesian higher education through interviews with 14 part-time and 11 full-time academics. Both groups identified more strongly with their teaching roles than with other roles. However, they differed in their perceptions of opportunities to enact their chosen academic roles and of the kind of academic development they needed. The current standardised model of academic development needs to be rethought to offer more flexibility and to invite departments’ participation in the development of their academics.
