Abstract The residents of an entire community are being examined periodically in an effort to determine the etiologic factors which lead to impaired health. As a part of this study, a submaximal test consisting of stepping onto an 8-inch bench at the rate of 24 steps/ minute for three minutes was administered to 2696 males and 2568 females, aged 10–69. The ECG, from which heart rate (HR) was measured, was recorded before, during, and after the exercise. Resting, exercise, and postexercise HR's are significantly higher for females at all ages. Pre-exercise HR decreases from age 10 to about age 25 in males and females, and shows little age change thereafter. In both males and females the terminal (3 minute) HR decreases from age 10 to 35, remains fairly constant to age 55, and decreases thereafter. The postexercise HR decreases again at age 65 in males and females. Reclining pre-exercise HR is moderately correlated with the exercise and postexercise HR at all ages in males and females. However, there is only a low correlation between either sitting or standing anticipatory HR and exercise and postexercise HR's. The HR's at 2′30” and 3′ during exercise are highly correlated as are the various postexercise HR's with each other at all ages and in both males and females. The correlation of the exercise HR and postexercise HR is moderately high. Percentile ranks for males and females (age 10–69) are given for the 1-minute postexercise HR's. 相似文献

Conclusions set forth in Serious and Violent Juvenile Offenders (1997) and other recent reports are remarkably similar to those that men and women on both side of the Atlantic had made a century ago: prevention is better than punishment; stable families are important; schools and communities must take a role in providing positive experiences for children and youth. The Revd William Byron Forbush, sociologist Charles Zueblin, philanthropist Louise de Koven Bowen and scores of other men and women also believed that ‘structured playground activities’ and after-school recreation programmes were important interventions. Chicago's Hull-House, which was inspired by Toynbee Hall, had developed extensive educational and recreational offerings for the youth of its community by the 1890s. Scores of settlement houses, which numbered over 200 by 1904, and other private endeavours directed their energies and resources to such programmes before the First World War. 相似文献

Meta-analysis is a statistical method that is increasingly utilized to combine and compare the results of previous primary studies. However, because of the lack of comprehensive guidelines for how to use meta-analysis, many meta-analysis studies have failed to consider important aspects, such as statistical programs, power analysis, publication bias, model selection, test of heterogeneity, and identification of heterogeneity. Therefore, the current study reviewed 84 meta-analysis studies conducted in Korea to examine proper application of the six categories named above. With regard to the issue of effect sizes, it was found that most of the meta-analysis studies obtained more than ten effect sizes, which seem to be an adequate number for representing an issue. However, many studies failed to consider the other issues: power analysis, publication bias, model selection, test of heterogeneity, and identification of heterogeneity. 相似文献

Web 2.0-based cultural diffusion occurs not only through viral word-of-mouth communication but also through Internet memes in which cultural consumers review, resemble, and recreate old cultural components, resulting in the creation of new cultural forms. YouTube features a platform for memetic creation with a host of user-generated parodies, reviews, and mashups derived from viral videos. This study examines the cultural ecosystem of YouTube memes inspired by Korean artist Psy’s viral production “Gangnam Style.” The study focuses on the salience of various genres of YouTube memes and structural connections between memetic videos. According to the results, the viral video of “Gangnam Style” sparked a sizable amount of user creativity, including remixes, parodies, self-directed performances, and reviews, among others. A network analysis of connections between memetic videos shows that various memetic genres drew different levels of audience attention and actions across various stages of the 3-month-long diffusion process. In addition, the content of the traditional mass media played a key role in giving the viral video wider publicity and acknowledgement, but this role was later shared by user-generated content. 相似文献

AbstractLooking at the current discourse on how to teach disaster, one apparent gap is that the scientific aspect of disaster is discussed and taught mostly in isolation from its human aspect. Disaster educators seem to be primarily interested in addressing issues such as social vulnerability, community resilience, personal action-related knowledge and emotion rather than the scientific basis of disasters, whereas science educators often fail to make connections between the scientific accounts of disasters and the social and political contexts that surround them. In this theoretical paper, I claim that this disconnect is problematic and that overcoming it is a key to understanding and teaching disaster in a more nuanced and comprehensive manner. Drawing primarily on science and technology studies (STS) on disaster, I explore the potential of interpreting disasters as failures of socio-technical systems, which helps us unearth the inner workings of the complex network of science, technology and society in the wake of calamities. STS challenges the dichotomous understanding of the material and social worlds and takes a view that they shape each other to constitute socio-technical systems. Taking such an approach to disaster allows a synthetic understanding of the natural, technological and human-made disasters that we are faced with in the age of uncertainty and complexity. Based on the ideas of STS and examples of recent disasters in East Asian countries, I argue that disaster education and science education can cross-pollinate in tackling the post-disaster hardship and cultivating responsible citizens. 相似文献
