全民阅读率和阅读水平在一定程度上决定一个民族的创造能力和发展潜力,是衡量一个国家社会文明程度的重要标志。因此,应根据阅读本身规律、国内外全民阅读经验和国家战略需要,采取适当的策略,推进我国全民阅读活动,构建全民阅读体系。     

Fitness Profiles and Activity Patterns of Entering College Students

Abstract

Fitness levels of American youth have shown a marked decline in the last decade, according to recent studies. To determine whether such a tendency persists for entering college students, the authors evaluated 115 male and 143 female students for performance on the following fitness-related variables: (1) maximal oxygen consumption (estimated from Astrand cycling protocol), (2) body composition (skin-fold techniques), (3) muscle endurance (sit-up protocol), (4) muscle strength (bench-press protocol), and (5) joint flexibility (upper and lower body protocols).

Although neither men nor women exhibited high levels of cardiorespiratory fitness, the women in the study showed higher relative levels than their male counterparts. Both groups showed excellent levels of muscle strength (compared with normative standards), but they achieved only an average standard for muscle endurance. Findings of relatively low levels of cardiovascular fitness compared with levels of muscle strength, particularly in men, seem to be a reflection of an inappropriate concentration of physical activity.     

An Evaluation of Physical Fitness Parameters for Graduate Students

Abstract

Although graduate physical therapy students are taught the principles of fitness for incorporation into their professional lives, they have difficulty finding the time to implement these principles during graduate school. The authors studied 3 successive classes of graduate physical therapy students at the beginning and ending of their respective programs. They found that the women's percentages of body fat were significantly greater over the period of the study. The men's lower extremity strength decreased at the slower speeds (60 degrees/second), and the women showed increased strength at the higher speeds (180 and 240 degrees/second, respectively). Male grip strength significantly increased over the period of the study. To decrease students' percentages of body fat and increase their strength, the authors asserted that physical therapy students should be allowed more time to participate in fitness activities during their graduate school years.     

Workplace flexibility: a model of change

The inception of When Work Works – a theoretical- and research-based model of change in promoting effective and flexible workplaces – dates back to the confluence of a number of factors in the early 1990s. One decade later, this ‘perfect storm’ of factors led to the creation of When Work Works, and two decades later, to this critical assessment of the foundation for and results of this model of change. When Work Works has used partnerships with nationwide business organizations with community chapters in combination with media coverage, educational events, the creation of tools and materials and grassroots methods to communicate well-researched information to employers that show workplace flexibility is not just a favor or perk for employees but can be a powerful strategy for promoting better outcomes for both employers and employees. The program has been responsible for implementing a rigorous award and providing numerous community-based recognition and educational events on workplace effectiveness and flexibility around the country and for assisting many employers to effectively create more flexible and effective workplaces. When Work Works has been designed around eight key principles for creating change on a national level. This paper presents the context in which When Work Works evolved, a detailed discussion of the eight principles of Families and Work Institute's model of change, its results and lessons other organizations may wish to apply in their own change initiatives.     

Collaborative Frame Construction in Social Movement Campaigns: Bisphenol-A (BPA) and Scientist–Activist Mobilization

Previous research has explored the definitional features of the processes of scientific expert activism but has been less clear regarding the dynamics of this scientific activism. This paper addresses these gaps in understanding by using an exploration of the state-based efforts and mobilizations to regulate the chemical Bisphenol-A (BPA) to identify and analyze the dynamics of interactions between scientists and activists as they collaborate in pursuit of movement objectives. Drawing primarily from interview data and participant observation, I explore how scientific experts—through collaboration and work with activists—impact the processes of movement framing, and how, in turn, the collaborative dissemination of these frames may contribute to movement goals. I argue that the relationships and coordination that developed between BPA scientists and activists resulted in a collaboratively crafted set of frames that were both scientifically rigorous and highly resonant to a public audience.     

Cartoons and AIDS: Safer Sex,HIV, and AIDS in Ralf König's Comics

Ralf König is the best-selling author of comic book novels, and his stories of gay men coming to terms with contemporary society have resonated with hundreds of thousands of German readers and film-goers. König's characters, like the author himself, have great difficulty adhering to the demand that condoms be used. The article describes how König develops this theme through a variety of works from 1985 through 1999, and analyzes the intertwined relationships among the author, his characters, and the society that is both portrayed in his works and that reads his works.     

Estimating Ethnic Genetic Interests: Is It Adaptive to Resist Replacement Migration?

Analyses of the costs and benefits of immigration have not considered the dependence of an ethny's reproductive fitness on its monopoly of a demarcated territory. Global assays of human genetic variation allow estimation of the genetic losses incurred by a member of a population when random fellow ethnics are replaced by immigrants from different ethnies. This potential loss defines an individual's ethnic genetic interest as a quantity that varies with the genetic distance of potential immigrants. W. D. Hamilton showed that self-sacrificial altruism is adaptive when it preserves the genetic interests of a population of genetically similar individuals. Ethnic genetic interest can be so large that altruism on behalf of one's ethny—'ethnic nepotism'—can be adaptive when it prevents replacement. It follows that ethnies usually have an interest in securing and maintaining a monopoly over a demarcated territory, an idea consonant with the universal nationalism of Bismarck and Woodrow Wilson.     

A male fitness advantage to wing reduction in the oriental chinch bug,Cavelerius saccharivorus okajima (heteroptera: Lygaeidae)

Summary A male fitness advantage to wing reduction was investigated for the oriental chinch bug,Cavelerius saccharivorus, which is wing dimorphic. Field surveys for the frequency of matings between wing morphs showed that the mating probability was much higher in brachypterous males than in macropterous males in the early breeding season. Brachypterous males copulated with not only brachypterous females but also macropterous females in this season. This led to a considerable rate (30%) of insemination of macropterous females just before emigration even in the early breeding season. A rearing experiment for the pre-reproductive period of females revealed that females mated with brachypterous males copulated and oviposited earlier than females mated with macropterous males. These results indicate that there is a fitness advantage to wing reduction in the males ofC. saccharivorus in terms of the earlier sexual maturation.
