The theme of this article is that, individually and collectively, the local education authorities in Wales have a distinctive history in the 20th century. The thesis is explored mainly by means of three case studies: the reaction of the local authorities to the Education Act of 1902, which eventually escalated into a national movement dubbed 'the Welsh revolt'; the response of some local authorities, particularly in industrial Wales, to the 1932 legislation which required them to replace their free secondary school places with special places; and the attempts of some councils to resist the largely clandestine attempts of the Ministry of Education and its Welsh Department to impose a tripartite system of secondary education against their wishes after 1944. This tradition of independent action in Wales bears on contemporary patterns of power and policy. The article concludes by suggesting that, in an education power structure now radically altered by the creation of the National Assembly for Wales in 1999, the local authorities are regarded more favourably than is the case in England and vested with significantly more responsibility, so making it likely that their future course will diverge increasingly from that of their English counterparts.  相似文献

Lexical competition that occurs as speech unfolds is a hallmark of adult oral language comprehension crucial to rapid incremental speech processing. This study used pause detection to examine whether lexical competition operates similarly at 7–8 years and tested variables that influence “online” lexical activity in adults. Children (n = 20) and adults (n = 17) were slower to detect pauses in familiar words with later uniqueness points. Faster latencies were obtained for words with late uniqueness points in constraining compared with neutral sentences; no such effect was observed for early unique words. Following exposure to novel competitors (“biscal”), children (n = 18) and adults (n = 18) showed competition for existing words with early uniqueness points (“biscuit”) after 24 hr. Thus, online lexical competition effects are remarkably similar across development.  相似文献

Firstly I look upon Britain as my homeland… Liberty, the love of home, tolerance and justice—these are some of the things which Britain has infused into most of her sons and daughters…. What does Britain mean to me?, I say ‘A home and the home of the good things in life’. (HAI.1.) Britain means to me my HOME. And I use ‘home’ in the fullest sense as after years spent abroad, it is always the one place I had a secret hankering to come back to (SM1.6) England is home and there's no place like home. That's what Britain means to me. With all its faults, it means just everything to me (MIL.9.) (Report on ‘What does Britain mean to you’, 1941)1  相似文献

At the turn of the twentieth century two great forces gripped Wales, a nation grappling to assert itself and discover its modern identity. A powerful rugby team captured the nation's imagination just as an unprecedented religious revival swept the land. The conflicts between these social trends would prove a battle for the heart and soul of Welsh people.  相似文献

Abstract

The main aim of this study was to develop and test psychometrically the Physical Education Predisposition Scale, to assess secondary school students' cost–benefit assessment of physical education (PE) participation (PE attitude affective and attitude cognitive) and self-perceptions (PE perceived competence and self-efficacy). Secondary aims were to explore how the two variables were related, and to investigate age and gender differences. Altogether, 315 Year 8 and 9 students (aged 12–14 years) from four North West England schools completed the Physical Education Predisposition Scale. Principal components analysis revealed the presence of a simple two-factor solution explaining 60.7% of the variance. Factor 1 (labelled Perceived PE Worth) reflected attitude affective and attitude cognitive (α = 0.91), and factor 2 (Perceived PE Ability) represented perceived competence and self-efficacy (α = 0.89). Significant positive correlations were observed between the factors (r = 0.67 to 0.71, P < 0.001). Boys scored significantly higher than girls on Perceived PE Worth (P < 0.001) and Perceived PE Ability (P = 0.02). Similarly, Year 8 students scored significantly higher than Year 9 students on Perceived PE Worth (P = 0.005) and Perceived PE Ability (P < 0.001). Our results support the potential of the Physical Education Predisposition Scale as a concise measurement tool for use in the PE setting, for both teachers and researchers.  相似文献

In this study, we examined the methods used and knowledge required by 16 elite men's gymnastic coaches in the development of skill progressions. Following in-depth interviews, a conceptual model representing the process of skill progression development was generated. We found that: (1) elite gymnastic coaches developed skill progressions through experimental practice, reflection and critical inquiry; (2) the development of skill progressions was underpinned by the coaches acquiring a mindset based on four further sub-components (i.e. skill progression refinement, current coaching knowledge, mental imagery and biomechanical understanding); and (3) coaches identified the importance of replication of the spatial and temporal characteristics of the final skill. The results are consistent with task analysis, reflective practice and the principle of specificity. Practically, these findings suggest the need to develop coaches with a more objective approach to skill progression development and a greater understanding of the controlling mechanisms inherent in such practices.  相似文献

Abstract

The aim of this study was to determine if critical parameters for elite performance could be identified among a population of female shot putters. The performance of seven of the top women shot putters competing at the 2002 USA National Championships was examined. Video data were captured using two Panasonic 60 Hz cameras and the best throws of each athlete were digitized and analyzed using a Peak Motus three‐dimensional motion analysis system. Thirty variables were examined for their effect on the distance of the throw. Correlation analysis indicated that measured distance was positively correlated with release speed (r = 0.97, p < 0.0003) and shoulder‐hip separation (r = 0.72, p < 0.06) and negatively correlated with release angle (r = ‐0.74, p < 0.056), rear knee angle at rear foot touchdown (r = ‐0.93, p < 0.003) and rear knee angle at release (r = ‐0.76, p < 0.047). Greater knee flexion angle at both rear foot touch down and release along with a neutral shoulder‐hip angle at release were identified as the most critical parameters for success among this sample of elite women shot putters. The unique observation about the knee positions at specific events should assist in new training and coaching developments.  相似文献

The traditional “horse” was replaced by a new vaulting “table” in artistic gymnastics competitions in 2001.The aim of this study was to determine whether the table led to a change in vaulting technique. This was achieved by comparing three-dimensional video-based analyses (50 Hz) of selected biomechanical discrete and continuous variables across four elite male gymnasts performing a series of handspring front somersault vaults on the traditional horse and the new table. Individual joint and inter-segment coupling (continuous relative phase) were used to quantify techniques used on the two apparatuses. Differences were attributed in part to the design and construction of the new table. No differences were observed for the approach and take-off from the board. Significant differences in hip flexion at board take-off and strike angle on the table were observed. One of the effects of the latter was an increase in vertical take-off velocity compared with the horse. Individual strategies were observed in hip and shoulder coordination patterns that were obscured when group data were considered. Close monitoring of the evolution of skill on this new apparatus is paramount for gymnastics coaching, and further studies of current elite competitive vaulting techniques are required.  相似文献

Tkachev on uneven bars is a release and re-grasp skill performed using variations of preparatory longswing techniques; the reasons why different techniques are chosen remains unclear. This study examined kinematic and key release parameters specific to three distinct techniques with the aim of understanding the relative benefits of each. During two international artistic gymnastics competitions six arch, straddle and pike longswings preceding the straddle Tkachev were recorded using twin video cameras. Calibration and movement images were digitised and reconstructed using 3D DLT. Shoulder and hip angular kinematics, angular momentum and key release parameters were compared between techniques. In the arch longswing, the first and second hip functional phases began significantly earlier than the straddle or pike. No significant differences were established for release parameters although large effect sizes for horizontal release velocity and angular momenta about the mass centre and bar were reported between the arch and other two variants. Therefore, the arch variant may provide the opportunity to develop more complex combinations following the Tkachev. Providing insight into mechanical advantages of specific longswing techniques, and highlighting those that elicit desirable characteristics offers the potential to provide coaches with objective data on technique selection and ultimately skill development.  相似文献

Individuals with impaired glucose tolerance (IGT) are at greater risk of developing diabetes than in normoglycaemia. The aim of this study was to examine the effects of 12-weeks exercise training in obese humans with IGT. Eleven participants (6 males and 5 females; 49±9 years; mean Body Mass Index (BMI) 32.4 kg · m(-2)), completed a 12-week brisk walking intervention (30 min per day, five days a week (d · wk(-1)), at 65% of age-predicted maximal heart rate (HR(max)). Anthropometric measurements, dietary intake, pulse wave velocity (PWV, to determine arterial stiffness) and blood pressure (BP) were examined at baseline and post intervention. Fasting blood glucose, glycosylated haemoglobin, insulin, blood lipids, indices of oxidative stress and inflammation (lipid hydroperoxides; superoxide dismutase; multimeric adiponectin concentration and high-sensitivity C-reactive protein) were also determined. Post intervention, PWV (9.08±1.27 m · s(-1) vs. 8.39±1.21 m · s(-1)), systolic BP (145.4±14.5 vs. 135.8±14.9 mmHg), triglycerides (1.52±0.53 mmol · L(-1) vs. 1.31±0.54 mmol · L(-1)), lipid hydroperoxides (1.20±0.47 μM · L(-1) vs. 0.79±0.32 μM · L(-1)) and anthropometric measures decreased significantly (P < 0.05). Moderate intensity exercise training improves upper limb vascular function in obese humans with IGT, possibly by improving triglyceride metabolism, which may subsequently reduce oxidative stress. These changes were independent of multimeric adiponectin modification and alterations in other blood biomarkers.  相似文献
