博洛尼亚进程有力推动了欧洲高等教育一体化,英国积极参与欧洲高等教育区建设,在质量保障方面与其保持高度一致,促进了欧洲高等教育的趋同发展。本文通过历史分析发现,英国高等教育质量保障系统包含科研评估、教学评估和机构审核,兼具质量改进与问责的双重功能,且表现出竞争导向、风险为本的市场问责发展趋势。在脱欧背景下,英格兰新成立的学生办公室也是高等教育国家干预与市场问责的进一步结合,并非英国的"求异"发展。英国乃至欧洲高等教育区的质量保障机制面临着机构多样性与标准相似性的张力,并将受到消费者"众口难调"质量观的挑战。  相似文献

This study explores science communication on Twitter by investigating a sample of tweets referring to academic papers in five different scientific fields. The specifications of science communicators on Twitter, the characteristics of those who initiate actions (by tweeting), the extent and quality of reactions (retweeting), individual and group interactions, and the distribution of tweets across types of engagement in the process of science communication (i.e., dissemination, consultation, and evaluation) were explored. A broad array of actors is involved in the communication of science on Twitter, with individual citizens and individual researchers playing an important role. In principle, this is promising for creating direct interaction, which can be difficult through more traditional mass media. The vast majority of communication activities regarding academic papers is undigested dissemination with almost no sign of debate, contestation, or collective reflection. Another general finding of this study is that bot accounts play a major role in the science communication landscape on Twitter.  相似文献

Arts policy has a longstanding relationship with the concept of “quality” and the ways in which organisations measure, evaluate and account for it. Culture Counts, an evaluation system and digital platform, compiles data from standardised evaluation surveys of different stakeholder groups – organisations, audiences, critics, funders and peers – and provides the means to compare and triangulate data in an accessible format. As a result, it claims to provide a more effective, democratic tool for quality measurement of art, which demonstrates the public value of funding [Department of Culture and the Arts, & Knell, J. (2014). Public value measurement framework: Measuring the quality of the arts. Perth: Department of Culture and the Arts.]. Through qualitative research with two consortia of organisations involved in Culture Counts pilot projects in Manchester, England and Victoria, Australia, we explore these claims, comparing the reception and promotion of the system in both countries and considering its potential incorporation into policy assessment frameworks and adoption within arts organisations’ existing evaluation capacities.  相似文献

This study examined the presence and strengths of determinants associated with consultation of an in-house expert on child abuse and neglect (CAN) by preventive child health care professionals who suspect CAN. This study also assessed the relationship between in-house CAN expert consultation and professionals’ performance of six recommended activities described in a national guideline on preventing CAN for preventive child health care professionals. A total of 154 professionals met the study’s inclusion criteria. They filled in a questionnaire that measured in-house consultation practices and twelve determinants associated with the professional, the in-house expert, and the organizational context. Bivariate and multivariate regression analyses were performed. Almost half of the participants (46.8%) reported to consult the in-house expert in (almost) all of their suspected CAN cases. Professionals who reported better recollection of consulting the in-house expert (i.e. not forgetting to consult the expert) (p = .001), who were more familiar with consultation (p = .002), who had more positive attitudes and beliefs about consultation (p = .011) and who reported being more susceptible to the behavior (p = .001) and expectations/opinions (p = .025) of colleagues regarding in-house expert consultation were more likely to consult the in-house expert. Furthermore, in-house expert consultation was positively associated with two of six key guideline activities: consulting the regional child protection service and monitoring whether support was provided to families. The implications of these results for improving professionals’ responses to CAN are discussed.  相似文献
