《学生体质健康标准(试行方案)》测试指标的可行性分析

通过对武汉理工大学学生的测试、统计和分析后发现:<学生体质健康标准(试行方案)>中身体素质和运动能力类的测试应重点放在力量、速度、耐力等指标上,柔韧素质不应作为大学生的测试指标;身体素质和运动能力类测试指标各备选项的选择,应为相互间关联系数较大或者所反映的身体素质相差无几的各指标,而不能将反映不同身体素质的指标放在一起备选或比较;肺活量的测试应选择能够全面反映心肺功能的动态指标为好;台阶试验因费时而将给<学生体质健康标准>的执行带来许多困难等问题.

医学期刊不仅要服务于医学和医疗卫生工作科研,还要为医学和医疗卫生工作科研发展提供学术引领。文章结合办刊实践就医学期刊如何通过编辑出版服务提升学术引领能力问题进行探讨。提出医学期刊要通过精准定位、合理设置栏目、创新选题策划及优先做好读者服务等,明确服务功能及其范围和方向,发挥学术引领作用;通过建立服务管理体系,优化服务机制,激发服务活力,保证服务质量;通过提高编辑的服务素养和能力,不断提升服务于医学科研和创新引领能力。     

Technological capital: an alternative to the digital divide

This paper identifies individuals’ accumulated history with Information and Communication Technologies (ICTs) as a replacement for the contested and outdated term ‘digital divide.’ We propose that an individual’s ability to benefit from their technological history consists of four factors: awareness, knowledge, access, and technological capacity of the user’s social collective. Together, these factors make up the individual’s level or amount of Technological Capital. The development of this construct was based on empirical research conducted in Soweto, South Africa, and through an analysis of the literature on assessing individuals’ accumulated histories. The concept of technological capital has the potential for application in fields in which ICTs are used for communication, capacity building, and identifying barriers to adoption of new technologies. The use of the concept may have implications for policy decisions, resource allocation, and future research into differences among individuals’ and communities’ ability to benefit from the introduction of new technologies.

Quality,Innovation, and Financial Sustainability

Entrepreneurial, independent digital media sites arose in response to disruption in the journalism industry brought on by emerging technologies. This study explores this trend in Latin America from the perspective of audiences. Based on surveys of readers of entrepreneurial digital news sites in Guatemala and Nicaragua, this mixed-methods study offers a snapshot of who these readers are and what they are interested in. Results showed readers of the Guatemalan and Nicaraguan news sites valued equally quality journalism and innovation, but differed when it came to the importance they placed on the sites’ business models. This study also illuminated a new dimension of innovation, one from the readers’ perspective. While some respondents associated innovation with use of new technologies, in general readers defined innovation as unique (to the region) and alternative (to mainstream media) ways of doing journalism; their definition, unlike that of journalists, was not necessarily technologically driven.

论连结热力学过程两态的任意性

所谓连结两态热力学过程的任意性,指的是连系确定的始、终两态的可能热力学过程有无穷多,包括了各种可能的做功和吸热特性的过程,当然违反热力学第一定律的过程除外。因此,给定了始、终态后对连系它们的过程的做功和吸热的特性不可能作任何判断。
