ABSTRACTAlthough libraries, archives and museums were historically linked as ‘cabinets of curiosity,’ professionalization within the domains in the 19th century seems to have divided these collections. The creation of different working practices and standards built up barriers between these cultural or ‘information’ objects. However, in recent years there has been a well-developed trend towards pan-domain collaborative work which is slowly re-uniting collections and re-establishing links between the specialists that care for them. This article outlines how a project in the Royal College of Surgeons of England brought the library, archive and museum staff together to create a more collaborative environment which has served to benefit the collections, their users, and the staff themselves. 相似文献

Difficulties in indexing the degree of motivation or attention to television by people in the same room with a “live” television set have long been recognized. One element of this problem has been the question of determining which member of the household actually makes the selection of specific program or channel, and whether there are differences between types of households or socio‐economic classes that are related to different patterns of channel or program selection. 相似文献

ABSTRACTAs academic institutions continue to renovate and remodel existing libraries to include colocated services, it is important to understand how this new environment requires the redefining of traditional library roles and responsibilities. This case study examines how Delaware County Community College redefined reference and research service by transitioning to a triage reference model. This includes how information desk staff and student workers at a single service point determine when to refer users to librarians and how this model has evolved based on specific situations and experiences. 相似文献

Abstract The aims of this study were to determine whether scapular and humeral head position can predict the development of shoulder pain in swimmers, whether those predictors were applicable to non-swimmers and the annual rate of shoulder pain in adolescent swimmers and non-swimmers. Forty-six adolescent swimmers and 43 adolescent non-swimmers were examined prospectively with a questionnaire and anthropometric measures. The questionnaire examined demographic and training variables. Anthropometric measures examined the distances between the T7 spinous process and the inferior scapula (Inferior Kibler) and T3 spinous process and the medial spine of the scapula (Superior Kibler), humeral head position in relation to the acromion using palpation, BMI and chest width. Shoulder pain was re-assessed 12 months later by questionnaire. Shoulder pain in swimmers was best predicted by a larger BMI (OR = 1.48, P = 0.049), a smaller Inferior Kibler distance in abduction (e.g. OR = 0.90, P = 0.009) and a smaller horizontal distance between the anterior humeral head and the anterior acromion (OR = 0.76, P = 0.035). These variables were not significantly predictive of shoulder pain in non-swimmers. Annual prevalence of shoulder pain was 23.9% in swimmers and 30.8% in non-swimmers (χ 2 = 0.50, P = 0.478). 相似文献

AbstractThe present study aimed to establish whether 2 weeks of high-intensity interval training would have a beneficial effect on aerobic fitness, fat oxidation, blood pressure and body mass index (BMI) in healthy adolescent boys. Ten adolescent boys (15.1 ± 0.3 years, 1.3 ± 0.2 years post-estimated peak height velocity) completed six sessions of Wingate-style high-intensity interval training over a 2-week period. The first session consisted of four sprints with training progressed to seven sprints in the final session. High-intensity interval training had a beneficial effect on maximal O2 uptake (mean change, ±90% confidence intervals: 0.19 L · min?1, ±0.19, respectively), on the O2 uptake at the gas exchange threshold (0.09 L · min?1, ±0.13) and on the O2 cost of sub-maximal exercise (–0.04 L · min?1, ±0.04). A beneficial effect on the contribution of lipid (0.06 g · min?1, ±0.06) and carbohydrate (–0.23 g · min?1, ±0.14) oxidation was observed during sub-maximal exercise, but not for the maximal rate of fat oxidation (0.04 g · min?1, ±0.08). Systolic blood pressure (1 mmHg, ±4) and BMI (0.1 kg · m2, ±0.1) were not altered following training. These data demonstrate that meaningful changes in health outcomes are possible in healthy adolescent boys after just six sessions of high-intensity interval training over a 2-week period. 相似文献

ABSTRACTDigital technologies are now considered important in shaping young people's engagement in and with health and physical activity. Recent discussions show that the use of digital technologies to track health and fitness may over-emphasize the linear understanding of the body and health generally underpinned by Western health ideologies such as healthism. Other studies have shown the increased use of digital technologies in teaching Health and Physical Education (HPE) and as a means to enhance health and increase physical activity. Despite the opportunities and risks apparent in these studies, little is known about how HPE students make choices, negotiate, and resist or embrace the digitalisation of physical activity, exercise, and more broadly health. This study examines HPE students’ meaning making of risk and surveillance associated with the self-digitisation of exercise. The study further investigates how the concept of ‘prosumption’; the production, curation and consumption of self-data within the context of digitised health and physical activity, is understood. Based on the findings, we have constructed a typology of prosumers that can be used as a pedagogical device to illustrate the various kinds of subject positions students take up with digital technology in health and physical activity. This study extends the current understanding of prosumers by identifying the ‘ambivalent prosumer’. The results provide insights that have direct pedagogical implications in HPE teacher education specifically in the areas of knowledge production and consumption of knowledge through digital technology in health and physical activity. 相似文献

The aim of this study is to examine the prevalence and correlates of adolescents’ resistance training (RT) skill competence. Participants were 548 adolescents (14.1 ± 0.5 years) from 16 schools in New South Wales, Australia. RT skills were assessed using the Resistance Training Skills Battery. Demographics, BMI, muscular fitness, perceived strength, RT self-efficacy, and motivation for RT were also assessed. The proportion demonstrating “competence” and “near competence” in each of the six RT skills were calculated and sex differences explored. Associations between the combined RT skill score and potential correlates were examined using multi-level linear mixed models. Overall, the prevalence of competence was low (range = 3.3% to 27.9%). Females outperformed males on the squat, lunge and overhead press, whereas males performed better on the push-up (p < .05). Significant associations were seen for a number of correlates, which largely differed by sex. Muscular fitness was moderately and positively associated with RT skills among both males (β = 0.34, 95%CIs = 0.23 to 0.46) and females (β = 0.36, 95%CIs = 0.23 to 0.48). Our findings support a link between RT skills and muscular fitness. Other associations were statistically significant but small in magnitude, and should therefore be interpreted cautiously. 相似文献

The aim of this study was to investigate if the effects of changes in physiological arousal on timing performance can be accurately predicted by the catastrophe model. Eighteen young adults (8 males, 10 females) volunteered to participate in the study following ethical approval. After familiarisation, coincidence anticipation was measured using the Bassin Anticipation Timer under four incremental exercise conditions: Increasing exercise intensity and low cognitive anxiety, increasing exercise intensity and high cognitive anxiety, decreasing exercise intensity and low cognitive anxiety and decreasing exercise intensity and high cognitive anxiety. Incremental exercise was performed on a treadmill at intensities of 30%, 50%, 70% and 90% heart rate reserve (HRR) respectively. Ratings of cognitive anxiety were taken at each intensity using the Mental Readiness Form 3 (MRF3) followed by performance of coincidence anticipation trials at speeds of 3 and 8 mph. Results indicated significant condition × intensity interactions for absolute error (AE; p = .0001) and MRF cognitive anxiety intensity scores (p = .05). Post hoc analysis indicated that there were no statistically significant differences in AE across exercise intensities in low–cognitive anxiety conditions. In high–cognitive anxiety conditions, timing performance AE was significantly poorer and cognitive anxiety higher at 90% HRR, compared to the other exercise intensities. There was no difference in timing responses at 90% HRR during competitive trials, irrespective of whether exercise intensity was increasing or decreasing. This study suggests that anticipation timing performance is negatively affected when physiological arousal and cognitive anxiety are high. 相似文献

ABSTRACTLow back pain (LBP) is a common problem in football (soccer) players. The effect of LBP on the trunk and hip muscles in this group is unknown. The relationship between LBP and trunk muscle size and function in football players across the preseason was examined. A secondary aim was to assess hip muscle strength. Twenty-five elite soccer players participated in the study, with assessments conducted on 23 players at both the start and end of the preseason. LBP was assessed with questionnaires and ultrasound imaging was used to assess size and function of trunk muscles at the start and end of preseason. Dynamometry was used to assess hip muscle strength at the start of the preseason. At the start of the preseason, 28% of players reported the presence of LBP and this was associated with reduced size of the multifidus, increased contraction of the transversus abdominis and multifidus muscles. LBP decreased across the preseason, and size of the multifidus muscle improved over the preseason. Ability to contract the abdominal and multifidus muscles did not alter across the preseason. Asymmetry in hip adductor and abductor muscle strength was found between players with and without LBP. Identifying modifiable factors in players with LBP may allow development of more targeted preseason rehabilitation programmes. 相似文献
