作为技术研究者的马克思

本文主旨在于讨论马克思的社会变革理论中技术和科学的地位与作用.文中强调了技术与经济间的相互作用和反馈关系,同时驳斥了将马克思当作技术决定论者的粗浅观点.马克思把技术看做人类和外部物质世界之间的媒介.通过对科学与技术的区分,指出机器生产的出现和科学在生产中的运用对于资本主义生产方式的重大意义.马克思还分析了资本品部门的特殊作用和资本主义趋向大规模生产的必然性,以及在资本主义条件下技术创新的各种形式.     

Physical education's role in public health: steps forward and backward over 20 years and HOPE for the future

The 1991 paper, "Physical education's role in public health" described the importance of physical education in addressing public health problems. On its 20th anniversary, this article reviews accomplishments in improving the health impact of physical education and identifies areas lacking progress. Major accomplishments include development of evidence-based programs, documentation of health and academic benefits of physical education, and acceptance of physical education as a public health resource. Additional work is needed to evaluate the uptake of evidence-based programs, improve national surveillance of physical education quantity and quality, establish stronger policies supporting active physical education, and achieve wide acceptance of public health goals within the physical education field. These opportunities constitute an agenda for actualizing the promise of health-optimizing physical education before the next 20 year anniversary.     

A Pictorial View of the Physical Activity Socialization of Young Adolescents Outside of School

Childhood obesity prevention has fallen short of anticipated impact. Therefore, intervention programs need to be redirected to other potential settings to increase youth physical activity. This qualitative study, using autodriven interview techniques, was conducted to identify out-of-school settings that youth perceive as important for physical activity. Sixty-six children took photographs involving their physical activity involvement. A subsample completed follow-up focus groups. Salient themes included types of physical activities related to free play, fitness, organized sports, and chores. Most photographs included multiple children of similar age and were taken outdoors. Data suggest children associate chores with physical activity and engage in fitness-related activities. In addition, friends and family, the outdoors, and importantly, the home emerged as natural intervention components that may prove useful towards decreasing the physical inactivity and obesity of youth.
