ABSTRACT Reliability of accelerometer-determined physical activity (PA), and thus the required length of a monitoring period, appears to depend on the analytic approach used for its calculation. We compared reliability of objectively measured PA using different resolution of data in a sample of 221 Norwegian 2–6-year-old children providing 2–3 valid 14-day periods of accelerometer monitoring (ActiGraph GT3X+) during September–October, January–February, and May–June 2015–2016. Reliability (intra-class correlation [ICC]) was measured for 1–14 days of monitoring across the measurement periods using linear mixed effect modelling. These results were compared to reliability estimated using different resolution of data using the Spearman–Brown formula. The measured reliability improved only marginally with increased monitoring length and levelled off after 5–6 days. Estimated reliability differed substantially when derived from different resolution of data: 3.9–5.4, 6.7–9.2, 13.4–26.7 and 26.3–87.7 days of monitoring was required to achieve an ICC = 0.80 using an hour-by-hour, a day-by-day, a week-by-week and a period-by-period approach, respectively. Reliability could not be correctly estimated from any single resolution of data. We conclude that reconsideration is needed with regard to how reproducibility of objectively measured PA is analysed and interpreted. 相似文献

What enhances innovation and value creation in the global knowledge economy? We offer several answers here, chief among them this: Leaders need to move away from focusing on developing innovations and value within the mental models, systems, and organizational solutions of the old industrial economy, with its firm- and product-centric view of value. Instead, they need to focus on providing tailor-made products and services to the newly connected and interconnected customer. They can do this with individualized immediate feedback, a new organizational logic, and new cooperating structures. 相似文献

A feature of academic literature on physical education teacher education (PETE) is the expectation that it can and should impact upon student teachers' beliefs and prospective practices in some significant ways. This is despite research over the last 20 years or more alluding to the apparent failure of PETE to ‘shake or stir’ (Evans et al., 1996) what might be termed the (typically conservative and conventional) pre-dispositions of student and early career PE teachers. In this article, we examine the perceptions of PE student teachers in Norway in order to ascertain just what it is that makes them so resistant to change and, for that matter, such infertile ground for sowing the seeds of reflexivity. The study involved semi-structured interviews with 41 PE student teachers from the three routes through teacher education available at Nord University College (Nord UC). Among the main themes identified in the data were the PE students' perceptions of: the purposes (and ostensible benefits) of school PE and PETE as well as the nature of PETE itself (including subsidiary themes of sporting and teaching skills, other ‘competencies’, school placements, mentoring and mentors, PETEs' (physical education teacher educators) teaching styles and the students teachers' relationships with the PETEs). The article concludes that, as far as the students at Nord UC were concerned, the significance of PETE revolved around the programme's efficacy in developing the sporting skills and teaching techniques they viewed as central to their preparation for teaching. The minimal impact of the more theoretical aspects of PETE appeared to be partly attributable to the students' perceptions of PE as synonymous with sport in schools and partly to their particularly pragmatic orientations towards PETE. In this vein, the students viewed experience as the most important, most legitimate ‘evidence’ on which to base their beliefs and practices and were resistant to the ‘theory’ of teacher education, rationalising their tendencies to select the evidence that suited them. 相似文献

In this paper, we examined the collaborative mentoring processes of a transnational network. A narrative approach was employed to explore the mentoring practices and experiences of 19 women involved in the CURVE-Y-FRiENDs (C-Y-F) network. Their mentoring practices go beyond transnational, ethnic, discipline, and university borders. The processes employed in the network can be conceptualized as pathways to professional relationships. The narratives of C-Y-F members illustrated collaborative mentoring as an expression of the personal and professional dimensions of support, which must be part of academic life. Collaborative mentoring relationships and discourse provided a response to the current inconsistencies in faculty mentoring practices and have implications for the ways in which administrations and faculty in general initiate more empathetic structures and procedures that better meet the mentoring needs of women and minority faculty in academia. 相似文献

This article discusses how Information and Communication Technologies can support 21st century assessment strategies and what needs to be done to ensure that technological advances support and foster pedagogical innovation. Based on an extensive review of the literature, it provides an overview of current ICT-enabled assessment practices, with a particular focus on the more recent developments of ICT-enhanced assessment tools that recognise 21st century skills. The article also refers to relevant cases of eAssessment, looks into examples of the potential of emerging technologies for eAssessment and discusses some relevant innovation and policy issues. Reflecting on these examples, it argues that, although technological challenges exist, the more pressing task at present is to transcend the traditional testing paradigm and conceptually develop (e)Assessment strategies that allow to more fully exploit the benefits of emerging technologies in order to foster the development of 21st century skills. 相似文献

In European societies, major patterns of plurality have changed over recent decades due to modernization and globalization. In schools, these new patterns of plurality have consequences for learning processes and may be challenging for students and teachers. This article investigates these issues, taking as its point of departure the way they surfaced in the Norwegian subject-oriented research project ‘Teaching about Religious Diversity in Schools. Applying and Developing an Interpretive Cultural Approach to Religious Education’ (2007–2010). Nine teachers and two researchers worked together in a community of practice, adopting an action research mode of collaboration. Each participant carried out and documented individual development projects, mostly within their own student groups. Developments and results were discussed in regular community-of-practice workshops. The data analysed in this article were generated from these workshops and from interviews with participants. The main research question raised is how an action research project in the field of religious education can lead to professional development for the participants. More specifically, the question is how such development can be described with respect to the relationship between personal and professional aspects of teacher identity and practice. The introduction of core concepts from theories of religious education and action learning triggered a collective inquiry among the participants into their own professional knowledge. Gradually a common professional discourse developed within the community of practice, and the participants became aware of and started to investigate critically how personal values and beliefs played a role in their professional work. 相似文献

The aim of this research is to develop and validate a self-report measure of mindfulness and coping, the mindful coping scale (MCS). Dimensions of mindful coping were theoretically deduced from mindfulness theory and coping theory. The MCS was empirically evaluated by use of factor analyses, reliability testing and nomological network validation. The study's participants were high school students from two high schools, covering all streams. Further validation was obtained by correlating the MCS-subscales with an appraisal theory-based measure of coping strategies. Results from factor analyses supported the proposed measurement model and Cronbach's alphas indicated good internal consistency for the four sub-scales. Furthermore, correlations with instrument for measuring coping were mainly in accordance with our expectations. The above supports the validation of our instrument. 相似文献

Terror attacks force democratic societies to mobilize, reinforce and rethink core values, including media freedom and freedom of speech. The present article analyzes how one traumatic event—the 2011 Oslo terror—challenged editorial practices related to editorial control and open debate in major Norwegian media organizations. Meeting the call for more research on disruptive media events in a hybrid media landscape, it illuminates how professional media balance critical debate with strategies for societal recovery in contemporary post-crisis contexts. Based on in-depth interviews with debate editors, the article documents how terror profoundly challenges editorial practices, routines and norms in media organizations with debates in multiple formats and platforms. In their online comment sections, the media organizations all moved towards a more interventionist policy introducing multiple new control measures. In the traditional op-ed formats, however, they selectively expanded the range of voices and included actors deemed too extreme prior to the attacks. Theoretically the article contributes to the literature on disruptive (key) events, editorial strategies during crisis, editorial control in contemporary media systems and editorial approaches to mediated deviance. 相似文献
