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

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

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

The purpose of this ethnographic study was to explore the development of belief systems as related to racial and ethnic identities of preservice teachers as they crossed cultural borders into science teaching. Data were collected throughout a yearlong teacher preparation program to learn how early life experiences and racial and ethnic identities of preservice teachers influenced both their beliefs about diversity in science classrooms and science teaching pedagogy. Case studies of three preservice teachers from diverse racial and ethnic background are presented: Asian American, African American, and Rural Appalachian. Using Bank's ethnicity typology, findings suggest that racial and ethnic identity, developed in early life experiences of preservice teachers, provided clarity on the rigidity of their beliefs about diversity and how they view science teaching. By learning about the border crossing experiences of preservice teachers in relation to their beliefs about diversity as related to racial and ethnic identities, the researchers hoped to provide insight on preparing preservice teachers for the challenges of working in diverse classrooms. © 2004 Wiley Periodicals, Inc.

Based on post-structural feminist and gender studies, the present article analyses the importance given to the practice of physical education, sports and exercise as part of the national policy to strengthen the Caucasian-Brazilian population at the beginning of the twentieth century, emphasising the priority made of the White female body as the most important instrument in strengthening the so called ‘White race’. All the editions of the Revista Educação Physica, the first magazine published specifically for physical education and sport in Brazil, was the primary research source. Other books, manuals, reviews from scientific congresses and official publications from the Brazilian Government at the time were also examined. Via the technical analysis of the contents of the aforementioned publications, it was possible to conclude that the Brazilian nationalist discourse at the time sought what was called the ‘refinement of the White race’ by strengthening its women while, at the same time, systematically ignoring Black women.  相似文献

This study employed a 2-year longitudinal design to examine the relation of stressful life events and social supports to psychological distress and school performance among 166 early adolescents (mean age = 13.5 years). A prospective approach was utilized to control for initial levels of adjustment when examining the relation of Time 1 stress and support variables to Time 2 psychological distress and school performance. Both stress and support variables made significant contributions to the prediction of subsequent psychological distress. Stresses, but not supports, made a significant contribution to the prediction of subsequent school performance. Evidence for reciprocal and interactive linkages was also found, including effects of psychological distress and school performance on subsequent stresses and supports, and greater adaptive impact of school-based supportive resources under conditions of heightened risk outside of school. Implications for ecological and transactional models of development relating to the targeting and efficacy of preventive efforts are discussed.  相似文献

Although advocates of home visits claim that they improve access to preventive interventions for socially disadvantaged families, home visiting programs often report high dropout rates. This study investigated factors predicting attrition in a sample of 434 low-income, first-time mothers in a German program modeled on the Nurse–Family Partnership program. Both participant characteristics and process variables associated with attrition were examined. The results indicated that 38.5% of the mothers left the program before completing 75% of the enrollment time; 62% of those left for addressable reasons (e.g., losing interest in program participation). Arguably, these participants might be retained through program modifications. Almost half of the dropouts left the program before completing 25% of the enrollment time. Program dropouts were younger and did not experience pregnancy-related risks. With regard to process variables, a high frequency of unsuccessful visit attempts and low maternal engagement during the home visits increased the risk for attrition. Self-referral, a high percentage of time spent on parenting issues as well as a high percentage of grandmother participation during visits contributed to participant retention. Among mothers with a high number of risk factors for child abuse and neglect, partner (husband or boyfriend) participation during visits positively influenced the retention rate. Since process variables explained a larger amount of variance in attrition compared to participant characteristics, it is reasonable to focus on the intervention processes when trying to reduce attrition.  相似文献
