CrossRef and the research experience     

Amy Brand 《Learned Publishing》2004,17(3):225-230

CrossRef is an independent membership association for building collaborative publishing technologies. Its mission is to provide services that enable the scholar to reach source material easily; it focuses on methods that are best achieved through collective agreement among publishers. The CrossRef network now covers millions of journal articles and other content items from hundreds of publishers. This article looks at CrossRef's significance for the online research experience, four years after the launch of the CrossRef initiative.  相似文献

Entwicklungsförderung im außerschulischen Kinder- und Jugendsport     

Dr. Christian Herrmann PhD  Prof. Ralf Sygusch PhD 《Sportwissenschaft》2014,44(1):25-38

The concept “Psychosocial Resources in Sport” (Sygusch, Ein sportartenorientiertes Förderkonzept für Schule und Verein. Schorndorf: Hofmann, 2007) substantiates methodical measures to systematically promote resources such as self-concept, self-efficacy, group cohesion, and social competence. In the PRimus-study this concept was implemented in handball and apparatus gymnastics over 7 months in 29 training groups (age: 12–16 years). The aim, amongst others, was to evaluate whether the concept is effective in child and youth sport. For this purpose a mixed-method design was chosen. The development of resources were measured through qualitative trainer interviews (n?=?39) as well as quantitative surveys of athletes (IG: n?=?374; KG: n?=?270) over three measurement times. The trainer statements show that the intervention initiated resource strengthening processes which indicate a promotion of resources. The quantitative measurements, however, do not reveal substantial changes throughout the intervention period. The change in behavior of coaches and athletes – regardless of the intervention measures – influences the development of resources. Overall, it must be noted that broad-based intervention concepts, which are also feasible, had difficulty proving the effects and the effectiveness.  相似文献

Establishing the structure of reality for an industry: model and anti-model arguments as advocacy in Nike's crisis communication     

Timothy Sellnow  Jeffrey Brand 《Journal of Applied Communication Research》2001,29(3):278-295

This study illustrates the potential role of model and anti-model arguments in organizational crisis communication. Specifically, model and anti-model arguments are described as a strategy for moving the focus of a crisis from an organization to its industry. Model arguments enable organizations to establish their corrective action as industry standards that merit imitation. Conversely, organizations can set minimum standards for their industries with anti-model arguments. Phil Knight's May 12, 1998, speech announcing Nike's new initiatives in global manufacturing is analyzed as a case study. The essay concludes that model and anti-model arguments can suspend criticism of the organization, create the foundation for a return to industry prominence by the organization, and establish proposed new industry standards that are favorable to the organization.  相似文献   

Home–School Literacy Bags for Twenty-first Century Preschoolers     

Susan Trostle Brand  Jessica Marchand  Elizabeth Lilly  Martha Child 《Early Childhood Education Journal》2014,42(3):163-170

Combining home–school literacy bags with preschool family literature circles provided a strong foundation for family involvement at home and school during this year-long Reading Partners project, and helped parents become essential partners in their children’s literacy development. Using home–school literacy bags, children and parents learned how to combine expressive arts and emergent literacy strategies including alphabet recognition, phonemic and phonological awareness, and oral language fluency. State-of-the-art activities designed for each of the multiple intelligences met the needs of diverse students with many different learning styles and interests. As families participated in fall and spring school-based Festivals in which they shared the literacy bags in small group family literature circles, they demonstrated children’s emerging literacy skills in a relaxed, yet highly engaging atmosphere.  相似文献   

Chronic morphine drinking establishes morphine tolerance, but not addiction in Wistar rats   总被引：1，自引：0，他引：1  

Binsack R  Zheng ML  Zhang ZS  Yang L  Zhu YP 《Journal of Zhejiang University. Science. B》2006,7(11):892-898

Objective： Some animal models apply morphine in the drinking water to generate addiction, but related reports are not free of conflicting results. Accordingly, this study aimed to figure out if chronic consumption of morphine in the drinking water can induce morphine addiction in Wistar rats. Methods： For 3 weeks, the animals received a daily morphine dose of 35 mg/kg by offering a calculated volume of sugar water （5% sucrose） with morphine （0. l mg/ml） to each rat; animals receiving just sugar water served as controls. Immediately after the treatment phase, the tail immersion test was used to check for morphine tolerance, and all animals were then kept on tap water for one week （withdrawal phase）. Afterwards, all rats were allowed to choose their drinking source by offering two bottles, containing sugar water without and with morphine, simultaneously for two days （preference phase）. Results： While the chronic consumption of morphine led to a reduction in body weight and to morphine tolerance, the morphine-treated Wistar rats did not show any preference for the opiate-containing sugar water. Conclusion： Body weight loss and tolerance do not reveal a condition of drug craving, and current animal models should be re-evaluated regarding their potential to establish morphine addicted animals.  相似文献
