J. Franklin Jameson and Waldo G. Leland remain forever linked in American archival history as the founders, respectively, of the National Archives and the American archival profession. From the immediate post-Revolutionary period until the eve of the First World War, American historians recognized that their nation's early history remained locked in European archives. However, not until the pioneering efforts of Leland, working under supervision of Jameson during the early 20th century, did any of these historical researchers bring to the United States, along with the voluminous copies of archival documents, the emerging tenets of European archival theory. This is the story of the collaboration between Jameson and Leland, and of Leland's efforts to professionalize American archival practice on the basis of European archival theory. 相似文献

Despite our society's increasing reliance on electronic documentation, to-date archives remain, largely, material repositories
of cultural memory. It is an accepted historical problematic, however, that culture is often resistant to material preservation.
There exists an undeniable and profound tension between scholarly efforts to reconstruct history and interpret cultural traditions
and the fragmentary, and often limited, material record. That is to say, scholarship is shaped by a sinuous negotiation around
the historical silences that encompass all of material culture. Historical silences, however, can at times be marginalized
(or at best excluded) by a sensitive configuration of material evidence with oral history.Excluding Archival Silences: Oral History and Historical Absence uses a historically and geographically specific example of oral history to engage in a more generalist discussion of how
oral reflection, especially when shaped by material evidences, can be an especially effective tool for preserving the dynamics
of culture that often remain undocumented. 相似文献

Cyberbullying is an increasingly common experience that produces psychosocial consequences for targets. Interventions encouraging bystanders to support targets of cyberbullying are limited by a lack of focus on what to communicate. This study considers supportive messages that emphasize emotional comfort, attributions of responsibility, and beliefs that people can change as relevant to this context, and it examines how perceptions of messages differ based on whether support providers have or lack experience with cyberbullying. We extend research on the indirect effects model of supportive communication by randomly assigning participants (N?=?304), who self-identify as targets of cyberbullying, to message and source conditions and assessing their perceptions of messages, providers, and outcomes. Impressions of messages mediate their influence on outcomes, and the experiential similarity of support providers moderates these effects. Certain messages, notably those contending that bullies can change, are less effective when delivered by sources who lack experience with bullying. 相似文献

Communication is constitutive—in theory. In research, however, communication is often treated as an outcome, influenced by personal attributes. The present research examines social communication competence as a constitutive influence predicting self-compassion and hope. Path analysis results support this hypothesis. Results show that social communication expressivity (β = .14), sensitivity (β = –.32), and control (β = .20) predict self-compassion. Social communication sensitivity (β = .26) and control (β = .27) affect hope agency, and social communication control (β = .29) predicts hope pathways thinking. These results provide evidence of the constitutive nature of communication. 相似文献

Binge-watching—the intensive, consecutive viewing of televised series—has become a prevalent usage pattern of entertainment media, which may influence users’ psychological well-being both positively and negatively: On the one hand, binge-watching could increase viewers’ enjoyment, recovery experiences, and vitality through an increase in perceived autonomy. On the other hand, binge-watching can trigger goal conflicts and feelings of guilt, which may reduce well-being. Drawing on an online survey (N = 499), the present study examines the tension between these two mechanisms and their effects on users’ well-being. The data largely support the hypotheses: Binge-watching is perceived as recreational as long as goal conflicts and feelings of guilt can be avoided. Well-being, on the other hand, is positively affected by binge-watching-induced increases in perceived autonomy. These results corroborate the central role of self-determination as a link between media reception, media enjoyment, and psychological well-being. 相似文献

Key points
- Accessibility is often misunderstood as a concept that is niche or of secondary importance.
- Reframing accessibility as improving the overall user experience instantly changes the perspective; accessibility becomes a critical requirement worthy of investment and resources.
- The single most prevalent complaint amongst librarians is the time it takes to get hold of accessible content.
- An accessibility roadmap provides structure and transparency for digital accessibility projects within the organization.
- Publishers' non‐compliance with accessibility standards will increase their risk of sales declines and legal complications over time.
- The SAGE A.C.C.E.S.S.I.B.L.E mnemonic offers suggestions on how to devise a successful accessible publishing programme.

The present research investigated whether co-viewer comments in social TV interactions are able to enhance or weaken media effects. With the example of talent shows, the valence of co-viewer comments (pro/contra/none) as well as the type of content (antisocial behavior vs. conventional performance) were varied in an experiment (N = 117). Results showed that participants’ own comments and their private attitudes about the judges varied in line with comment valence. Findings suggest that social TV viewers are prone to social influence of their co-viewers, which might amplify problems regarding the portrayal of antisocial behavior in reality TV. 相似文献

Textbook vetting and evaluation process intends to ensure that the materials provided are relevant, of the required quality, suitable ad would enhance learning efficiency and effectiveness. The paper investigates the role of publishers and Tanzania Institute of Education (TIE) in the textbooks vetting and evaluation process; examines factors used to vet, evaluate and approve primary and secondary school textbooks in Tanzania and proposes Strategies that would enhance the textbook vetting, evaluation and process. The study used a mixed method research design. Respondents were selected educational publishers; MoEVT, Baraza la Kiswahili Tanzania, TIE, and Publishers Association of Tanzania. Questionnaire and semi- structured interview were used to collect data which were analysed qualitatively and quantitatively. Major findings of the study were; textbooks vetting and evaluation process is not professionally conducted although standard criteria have been established; there is not well established roles among key players involved in the vetting and evaluation process leading to conflict of interest between TIE and the publishers. The study recommends establishing an independent professional evaluation board and a well-defined timetable and effective communication among various players; enacting a book policy and adopting a limited multiple-textbook publishing system. 相似文献
