Effect of environmental constraints on multi-segment coordination patterns during the tennis service in expert performers

The aims of this study were to examine the effect of different environmental constraints on kinematic multi-segment coordination patterns during the service and its coordination with service time variability. Ten expert tennis players (Age: 34.1 ± 5.3) volunteered to take part in this study. Participants served 30 times in 3 different conditions: control, target and opposition. The order of conditions was counterbalanced between participants. A wireless 3D motion capture system (STT Co, Spain) was used to measure 7 joint motions, with a 17 degrees of freedom biomechanical model created to capture the entire service action. Results of the principal component analysis showed that 4 synergies were created; however, their roles were changed relative to the perception of the environment. The results of repeated-measures analysis of variance did not show any significant difference on total variance and individual principal components between conditions; however, one synergy pattern significantly predicted the service time variability in both control and opposition conditions. In conclusion, the findings demonstrated that expert performers reduce the joint dimensionality by creating functional synergies in different phases of service and adapt the service action according to the perception of the environment.     

Shirt sponsorship by gambling companies in the English and Scottish Premier Leagues: global reach and public health concerns

While the nature of gambling practices is contested, a strong evidence base demonstrates that gambling can become a serious disorder and have a range of detrimental effects for individuals, communities and societies. Over the last decade, football in the UK has become visibly entwined with gambling marketing. To explore this apparent trend, we tracked shirt sponsors in both the English and Scottish Premier Leagues since 1992 and found a pronounced increase in the presence of sponsorship by gambling companies. This increase occurred at the same time the Gambling Act 2005, which liberalized rules, was introduced. We argue that current levels of gambling sponsorship in UK football, and the global visibility it provides to gambling brands, is a public health concern that needs to be debated and addressed. We recommend that legislators revisit the relationship between football in the UK and the sponsorship it receives from the gambling industry.     

Characteristics and experiences of interns in strength and conditioning

Student coaches undertake internships to develop practical skills and gain experience to improve employability prospects. The characteristics of the coaches who undertake these internships, their experiences and the nature of the work being performed are currently unknown. The purpose of this study was to report the characteristics of strength and conditioning (S&C) coaches who have undertaken internships and their experiences during their respective placements. A total of 113 men and 6 women completed an online survey. Placements generally lasted 6–12 months (66%), were unpaid (93%) and took place at professional teams (63%). All respondents had a standard of experience prior to commencement (82%); a higher-education degree (bachelor’s degree 56%; master’s degree 18%) and others were qualified S&C coaches (16%). Activities consisted largely of coaching (47%), data collection (22%) and equipment set-up (25%) but lacked provision of appropriate training. Mentors were allocated to interns; however, often developmental objectives were not discussed, meetings were rarely documented, and in some cases, no meetings took place. This study suggests that internships offer worthwhile experiences and assistance in skill development to progress in S&C. However, clearer guidelines are required to define the responsibilities of employers and interns, to maximise these experiential learning opportunities and avoid the exploitation of willing students.     

The practice of cultural ecology: network connectivity in the creative economy

ABSTRACT

This paper reflects on approaches to collaborative knowledge exchange projects between UK universities and the creative economy. It develops a preliminary account of cultural ecology as a systematic approach to producing impact in the creative economy. It argues that such an approach is a powerful way to aggregate micro-businesses and small and medium sized enterprises in a meaningful network of new relationships. The paper uses social network analysis software to begin to visualise the pattern of relationships that constitute the ecosystem. The paper reports on the work of the Research and Enterprise for Arts and Creative Technologies Hub, one of four Knowledge Exchange Hubs for the Creative Economy established by the Arts and Humanities Research Council.     

The art of the good life: culture and sustainable prosperity

ABSTRACT

The creative economy has seen cultural policy swallowed up by a narrow vision of economic growth, its impacts on the urban fabric captured by property developers, and its promises of meaningful activity challenged by the exploitation and inequities of cultural labour markets. So it needs to be abandoned and re-thought, but on what basis? This paper analyses the potential for cultural work to encourage alternative visions of the “good life”, in particular, how it might encourage a kind of “sustainable prosperity” wherein human flourishing is not linked to high levels of material consumption but rather the capabilities to engage with cultural and creative practices and communities. We critically explore these ideas in three locations: a London borough, a deindustrialised city in England’s midlands and a rural town on the Welsh/English border. Across these diverse landscapes and socio-economic contexts, we look at different versions of the good life and at the possibilities and constraints of cultural activity as a way of achieving kinds of sustainable prosperity.     

Secondary science and mathematics teachers and gender equity: Attitudes and attempted interventions

Although the literature documents the potential impact of teachers on the achievement of young women in science and math, few studies investigate teacher attitudes and the use of teacher interventions. A survey containing both fixed-response and open-ended questions was administered to 56 teachers from eight high schools. Open-ended questions were content analyzed, and log-linear modeling and chi-square tests of independence were used to analyze relationships between categorical variables representing demographic characteristics, teacher attitudes, and teacher use of interventions. Results provide evidence that teachers, regardless of demographic characteristics, are concerned about gender inequity in their classrooms, although they are generally not familiar with the wide range of possible causes (including their own actions). Reported interventions are consistent with those recommended in the literature, although teachers are not familiar with the effectiveness of their interventions, and numerous teachers feel that attempting interventions is a form of reverse discrimination. © 1996 John Wiley & Sons, Inc.     

The Influence of Direct and Overheard Messages on Children's Attitudes Toward Novel Social Groups

Individuals often develop negative biases toward unfamiliar or denigrated groups. Two experimental studies were conducted to investigate the extent to which brief negative messages about novel social groups influence children's (4- to 9-year-olds'; N = 153) intergroup attitudes. The studies examined the relative influence of messages that are provided directly to children versus messages that are overheard and examined whether the force of these messages varies with children's age. According to implicit and explicit measures of children's intergroup attitudes, children rapidly internalized messages demeaning novel groups, thus forming negative attitudes toward outgroups merely on the basis of hearsay. These effects were generally stronger among older children, and were particularly pronounced when the message was provided directly to children.
