Pacing accuracy during an incremental step test in adolescent swimmers

To assess pacing accuracy in a group of adolescent swimmers during an incremental step test. Fifteen well-trained swimmers (age 15±1.5 years; height 170.2±8.8 cm; mass 60.2±6.6 kg), completed two 7×200 m tests, separated by ~72 hours. They swam to a predetermined incrementally increasing pace per step and were instructed to swim at even pace. Upon completion of each step, rating of perceived exertion, heart rate and blood lactate were recorded. Significant differences observed for both trials between actual and predicted swim time (P<0.05). Significant differences also observed between the first and second 100 m of each step in trial 1 for step 1 (P=0.001, effect size [ES] =0.54), step 2 (P=0.0001, ES =0.57), step 4 (P=0.0001, ES =0.53), step 5 (P=0.005, ES =0.65), step 6 (P=0.0001, ES =0.50), and step 7 (P=0.0001, ES =0.70). Similar responses witnessed for trial 2 (P<0.05). Findings suggest that the finite anaerobic capacity was engaged sooner than would normally be anticipated, as a function of an inability to regulate pace. This is proposed to be a consequence of the volume of exposure to the biological and psychological sensations and cognitive developmental status. Given the apparent error in pacing judgment exhibited in this population group, caution should be applied when adopting such tests to monitor training responses with adolescent athletes, and alternate means of modulating pace be investigated

The 'Parekh Report' - national identities with nations and nationalism

‘Multiculturalists’ often advocate national identities. Yet few study the ways in which ‘multiculturalists’ do so and in this article I will help to fill this gap. I will show that the Commission for Multi-Ethnic Britain’s report reflects a previously unnoticed way of thinking about the nature and worth of national identities that the Commission’s chair, and prominent political theorist, Bhikhu Parekh, had been developing since the 1970s. This way of thinking will be shown to avoid the questionable ways in which conservative and liberal nationalists discuss the nature and worth of national identities while offering an alternative way to do so. I will thus show that a report that was once criticised for the way it discussed national identities reflects how ‘multiculturalists’ think about national identities in a distinct and valuable way that has gone unrecognised

Mirror Energy Differences at Large Isospin Studied through Direct Two-Nucleon Knockout

The first spectroscopy of excited states in 52Ni (Tz=2) and 51Co (Tz=-3/2) has been obtained using the highly selective two-neutron knockout reaction. Mirror energy differences between isobaric analogue states in these nuclei and their mirror partners are interpreted in terms of isospin nonconserving effects. A comparison between large scale shell-model calculations and data provides the most compelling evidence to date that both electromagnetic and an additional isospin nonconserving interactions for J=2 couplings, of unknown origin, are required to obtain good agreement.Comment: Accepted for publication in Physical Review Letter

Barriers and Facilitators of Physical Activity in Children of a South Asian Ethnicity

Children of South Asian ethnicity residing in England have low levels of physical activity. Limited literature exists on correlates, barriers and facilitators to activity in South Asian children. The aim of this study was to fill this gap in the literature. Interviews were conducted with 10 parents of South Asian ethnicity residing in the UK. Interviews covered a description of the family setup, participants’ opinions of physical activity including barriers and facilitators and their children’s participation, as well as approaches to general parenting, and how children spend their free time. Data were analysed using thematic analysis. Key themes identified included (i) restraints on parents’ and children’s time to be physically active, (ii) the role of the family in children’s physical activity participation, (iii) situational barriers to physical activity, (iv) physical activity not a priority, (v) opportunities to be active, (vi) perception of activity level and health. A number of key barriers to South Asian children’s participation in physical activity were identified, including (i) restraints on parents and children’s time, (ii) parents providing limited support for physical activity, (iii) physical activity has a low priority. A number of facilitators were also identified (i) play, (ii) school-time, (iii) extra-curricular clubs. In this sample of South Asian parents residing in the UK several socio-cultural barriers and facilitators of their children’s physical activity have been identified. The study provides preliminary data for a larger study to ascertain if such barriers and facilitators are representative of the wider South Asian community, so that recommendations for intervention and policies can be made

В ЗАЩИТУ ЭЛИТИЗМА

Current article of Roger Scruton is considering elitism in terms of positive distinction between people as recognition of their ones through their achievements. Also elitism is considering as necessary element of society that helps it to develop.  However, modern society aims to equality all people and destroying any kind of distinction. This situation leads to devaluation of human contribution to development of society, leads to stagnation.В данной статье Роджера Скратона рассматривается элитизм как стремление человека к признанию его статуса через его достижения. Элитизм также рассматривается как необходимый для развития самого общества элемент. Однако, современное общество стремится к уравниванию всех людей и упразднению отличий, что девальвирует ценность человеческих заслуг и обесценивает вклад людей в развитие самого общества, ведёт к стагнации

Rethinking the social impacts of the arts

The paper presents a critical discussion of the current debate over the social impacts of the arts in the UK. It argues that the accepted understanding of the terms of the debate is rooted in a number of assumptions and beliefs that are rarely questioned. The paper goes on to present the interim findings of a three‐year research project, which aims to rethink the social impact of the arts, with a view to determining how these impacts might be better understood. The desirability of a historical approach is articulated, and a classification of the claims made within the Western intellectual tradition for what the arts “do” to people is presented and discussed

Mirrored one-nucleon knockout reactions to the Tz=± 32 A=53 mirror nuclei

Background: The study of excited states in mirror nuclei allows us to extract information on charge-dependent (i.e., isospin-nonconserving) interactions in nuclei. Purpose: To extend previous studies of mirror nuclei in the f72 region, investigating charge symmetry breaking of the strong nuclear force. Methods: γ-ray spectroscopy has been performed for the mirror (Tz=±32) pair Ni53 and Mn53, produced via mirrored one-nucleon knockout reactions. Results: Several new transitions have been identified in Ni53 from which a new level scheme has been constructed. Cross sections for knockout have been analyzed and compared with reaction model calculations where evidence is found for knockout from high-spin isomeric states. Mirror energy differences between isobaric analog states have been computed, compared to large scale shell-model calculations, and interpreted in terms of isospin-nonconserving effects. In addition, lifetimes for the long-lived Jπ=521- analog states in both Mn53 and Ni53 have been extracted through lineshape analysis, giving half-lives of t12=120(14) ps and t12=198(12) ps, respectively. Conclusions: The inclusion of a set of isovector isospin-nonconserving matrix elements to the shell-model calculations gave the best agreement with the experimental data

What was Progressive in ‘Progressive Conservatism’?

In January 2009 David Cameron announced that the ‘underlying philosophy’ of his government would be progressive conservatism. Despite the ambiguity about this term, it was generally interpreted as a signal that Cameron was moving his party to the left.To some commentators, Cameron was allying with the progressive ‘one nation’ strand of conservative thought.To others, particularly in the media, he was drawing on the more immediate influence of Phillip Blond’s ‘Red Toryism’. However, the focus on the market (as opposed to state or community) found in both Cameron’s speech and subsequent policies sits uneasily with both of these interpretations. Cameron’s progressive conservatism has more in common with Thatcherism – an earlier conservative modernising project – than it does with centrist forms of conservative progressivism. Cameron’s progressive conservatism is progressive, but only in particular, less commonly used, ways – not as a rediscovery of social justice
