This study aimed to analyse the association between socioeconomic status (SES) and fatness and fitness in preschoolers. 2,638 preschoolers (3–5 years old; 47.2% girls) participated. SES was estimated from the parental educational and occupational levels, and the marital status. Fatness was assessed by body mass index (BMI), waist circumference (WC), and waist-to-height ratio (WHtR). Physical fitness components were assessed using the PREFIT battery. Preschoolers whose parents had higher educational levels had lower fatness (P < 0.05). BMI significantly differed across occupational levels of each parent (P < 0.05) and WHtR across paternal levels (P = 0.004). Musculoskeletal fitness was different across any SES factor (P < 0.05), except handgrip across paternal occupational levels (P ≥ 0.05). Preschoolers with high paternal occupation had higher speed/agility (P = 0.005), and those with high or low maternal education had higher VO2max (P = 0.046). Odds of being obese and having low musculoskeletal fitness was lower as SES was higher (P < 0.05). Those with married parents had higher cardiorespiratory fitness than single-parent ones (P = 0.010). School-based interventions should be aware of that children with low SES are at a higher risk of obesity and low fitness already in the first years of life. 相似文献

This study examined how goal-directed self-talk may help basketball players to self-regulate in stereotypical competitive situations: seconds before a challenging game, while clearly winning or clearly losing, and at the close of a tight game. Participants were recruited in groups of three to four, until preliminary inspection of the data indicated that data saturation was reached. In the end, 34 basketball players voluntarily took part in individual interviews, writing up to three self-instructions they had used in each of the four competitive situations to self-regulate. Content analyses revealed that self-talk in competitive basketball situations serves cognitive functions (e.g., regulating cognition and behaviour), motivational functions (e.g., promoting mastery goals) and emotion and activation-regulating functions (e.g., creating activated states). More specifically, the results also indicated that athletes’ self-talk may serve functions specific to the psychological demands experienced in each situation. It is argued that knowing how athletes counsel themselves, could prove important for applied sport psychologists to design psychological skill training. 相似文献

In Ferguson, Missouri, Palestinian activists and black protesters created a transnational collective identity defined by what some scholars call a “community of feeling” following the murder of Michael Brown in August 2014. This paper focuses on the transnational politics of the Ferguson Movement through a textual analysis of digital media discourse and interviews with local community activists. Findings reveal that activists generated a transnational collective identity based on their shared experiences of oppression and resistance, which activists made visible across various digital platforms, including social media, blogs, and livestreaming. Informed by the literature on social movements, collective identity, and affect, the authors move beyond theoretical analyses that emphasize activists’ communicative practices as strategic; instead, this article underscores the affective linkages that led to the development of a transnational collective identity within the movement. 相似文献

A new approach to narrative abstractive summarization (NATSUM) is presented in this paper. NATSUM is centered on generating a narrative chronologically ordered summary about a target entity from several news documents related to the same topic. To achieve this, first, our system creates a cross-document timeline where a time point contains all the event mentions that refer to the same event. This timeline is enriched with all the arguments of the events that are extracted from different documents. Secondly, using natural language generation techniques, one sentence for each event is produced using the arguments involved in the event. Specifically, a hybrid surface realization approach is used, based on over-generation and ranking techniques. The evaluation demonstrates that NATSUM performed better than extractive summarization approaches and competitive abstractive baselines, improving the F1-measure at least by 50%, when a real scenario is simulated. 相似文献

ABSTRACT Drawing upon a unique large-scale data source (n=5,004) and motivated by the time allocation model of consumer demand in economics, this paper critically analyses the relationship between the expenditure from, and duration of, same-day visits that comprise a large component of the domestic tourism market in England. It focusses on the contribution of activity sports tourism as a component of same-day visits. Three-stage least squares (3SLS) instrumental variable estimation is employed to account for the simultaneous determination of duration and expenditure as implied by economic theory. Controlling for socio-economic characteristics and general trip behaviours, the research identifies that although total expenditures and trip durations are positively related, there are trade-offs between these when focussing on the direct effects of the activities undertaken. However, accounting for the interrelationship between the duration of visits and the expenditures on them, it is found that walking reduces the expenditures on trips and their duration. Field sports increase them both. No effects are identified for running and cycling, as land-based activity sports tourism, or swimming and water sports, as water-based activity sports tourism. The key drivers of expenditure, which also increase the duration of trips, are visiting attractions and hospitality. The research provides a theoretically informed and empirically robust foundation for a more nuanced and targeted activity sports tourism strategy, which might have implications for how activity sports tourism may contribute to health and well-being and local economic development to better inform tourism planning and policy. 相似文献

Following the fall of the Iron Curtain in December 1989, the Romanian system of education has started a deep process of reconstruction that asked for a comprehensive package of reforms among which decentralisation. Broadly the paper aims to make a contribution to the emerging knowledge base about the realities of restructuring of post‐communist education systems and the impact that governance through markets is having on public services. The paper focuses on presenting and discussing the attempts to decentralise pre‐higher education in Romania in considering the role of the state and governance in the provision of public services and the introduction of market mechanisms in education. The decentralisation of education has been proposed by the then Minister of Education Andrei Marga. Although decentralisation in pre‐higher education has been piloted for three academic years and the policy documents that introduced it have been permanently amended and updated, more than a decade later, this reform has not reached its aims mainly due to the various changes on the political scene. However, provided that no major amendments will be made to the Laws of National Education (2009), decentralisation in pre‐higher education will be a reality from 2010–11. 相似文献

This study explores the beliefs and attitudes that university students enrolled in teacher education programmes in Spain, England and the US (Texas) hold about individuals who differ. A beliefs and attitudes toward difference scale (BATD) was constructed using nine dimensions of diversity; culture, language, socioeconomic status/social class, religion, gender, sexual orientation, political ideology, disability and special talent. A two‐way factorial analysis of variance indicated significant main effects due to the respondent groups on culture, religion and sexual orientation; significant main effects of worldview of difference on political ideology; and no interaction between the two factors on each of the nine domains of difference. An exploratory factor analysis was also performed in order to explore the viability of the theoretical model. The data suggest that attitudes towards people who differ include etic, emic and individual properties. These are discussed in terms of the uses of cross‐cultural data and further research opportunities. 相似文献

The paper contributes to research on innovation systems in general and, in particular, to the current debate on rationales for innovation policy by providing a framework to identify systemic problems in a given system of innovation and test the framework empirically. The data were drawn from the Thai Community Innovation Survey in the period after which a major change in the country's innovation system policy had been initiated. By hierarchical factor analysis, systemic problems are identified and grouped into four components: institution, network, Science and Technology infrastructure and other support services. The analysis allows researchers to investigate the mismatch between policies and problems and identify policy gaps. 相似文献

The purpose of this study was to determine differences in hamstrings-to-quadriceps (H/Q) peak torque ratios evaluated at different angular velocities between men and women who participate in judo, handball or soccer. A total of 166 athletes, including 58 judokas (26 females and 32 males), 39 handball players (22 females and 17 males), and 69 soccer players (17 females and 52 males), were evaluated using an isokinetic dynamometer. The H/Q isokinetic peak torque ratios were calculated at angular velocities of 1.05 rad · s?1 and 5.23 rad · s?1. In the analysis by gender, female soccer players produced lower H/Q peak torque ratios at 1.05 rad · s?1 than males involved in the same sport. However, when H/Q peak torque ratio was assessed at 5.23 rad · s?1, there were no significant differences between the sexes. In the analysis by sport, there were no differences among females at 1.05 rad · s?1. In contrast, male soccer players had significantly higher H/Q peak torque ratios than judokas (66 ± 12% vs. 57 ± 14%, respectively). Female handball players produced significantly lower peak torque ratios at 5.23 rad · s?1 than judokas or soccer players, whereas males presented no ratio differences among sports At 5.23 rad · s?1. In the analysis by velocity, women's muscular ratios assessed at 1.05 rad · s?1 were significantly lower than at 5.23 rad · s?1 for all sports; among men, only judokas presented lower ratios at 1.05 rad · s?1 than at 5.23 rad · s?1. The present results suggest that sport modality and angular velocity influence the isokinetic strength profiles of men and women. 相似文献

This study examines the relationship between drawing and oral language acquisition in deaf students aged three to five. The
sample is made up of one hundred participants: fifty deaf and fifty hearing children. Goodenough's Human Figure Drawing Test
and the WPPSI Scale of Intelligence geometric design subtest have been used to evaluate graphic representation. The deaf participants'
oral language has been assessed using the GAEL-P test. The main findings were that there were no significant differences between
the populations studied in terms of graphic representation. The oral language level of the deaf population does not correlate
with the level of their geometric designs, but does with the complexity of the drawing of the human figure at the age of 5.
The main conclusion with respect to the relationship between oral language and figurative drawings suggests that different
representations of symbolic functions should be integrated into children's education, especially in the case of deaf children. 相似文献
