This paper is the first of two Learned Publishing articles in which we report the results of a series of interviews with senior publishers and editors exploring open access megajournals (OAMJs). Megajournals (of which PLoS One is the best known example) represent a relatively new approach to scholarly communication and can be characterized as large, broad‐scope, open access journals that take an innovative approach to peer review, basing acceptance decisions solely on the technical or scientific soundness of the article. This model is often said to support the broader goals of the open science movement. Based on in‐depth interviews with 31 publishers and editors representing 16 different organizations (10 of which publish a megajournal), this paper reports how the term ‘megajournal’ is understood and publishers’ rationale and motivations for launching (or not launching) an OAMJ. We find that while there is general agreement on the common characteristics of megajournals, there is not yet a consensus on their relative importance. We also find seven motivating factors that were said to drive the launch of an OAMJ and link each of these factors to potential societal and business benefits. These results suggest that the often polarized debate surrounding OAMJs is a consequence of the extent to which observers perceive publishers to be motivated by these societal or business benefits.  相似文献

Primary–secondary school transition encompasses multiple social, academic and environmental changes which can negatively impact children’s emotional well-being. Children with Social, Emotional and Mental Health difficulties (SEMH) are believed to be especially vulnerable during this time. However, the voices of children with SEMH are heavily underrepresented in this field within practice and research. The present case study examined how children with SEMH difficulties within one special school experience primary–secondary school transition and how they are supported, in order to make recommendations to improve this period. The case study was qualitative and longitudinal, conducted over 18-months and methodologies included ethnographic observations, child photo-elicitation focus groups (with 11 Year 6 children) and three adult interviews. Findings demonstrated that over primary–secondary school transition children with SEMH difficulties (a) negotiate significant structural changes in support (often unanticipated) and (b) need to feel a sense of safety and belonging. To manage this effectively, transition provision for children with SEMH difficulties needs to consider their short-term emotional well-being whilst still in primary school, in addition to their long-term well-being looking ahead to secondary school. Greater collaboration and communication across schools and stakeholders can help ensure children receive continuity in standards and support.  相似文献

This paper presents (i) a purpose-built conceptual model for professional learning and (ii) a leadership framework designed to support a large-scale project involving diverse sites across the state of Queensland, Australia. The project had as its focus teacher-capacity building and ways to improve literacy and numeracy outcomes for students at educational disadvantage. It involved 15 intersectoral clusters and brought together Middle School teachers, principals, curriculum leaders and management personnel from Education Queensland, the Association of Independent Schools Inc., and the Catholic Education Commission. In the paper we discuss how the project worked at the interface of research and practice. Further, we discuss how professional learning was facilitated by a multi-layered approach that acknowledged the importance of research-based learning, curriculum and pedagogic leadership by principals, and strong opportunities for teacher agency through cross-cluster and intersectoral collaboration. In conclusion, we invite readers to consider how the approach represents a radical new way to think about what could count as valued professional learning interactions.  相似文献

Behavioral aspects of self-regulation, including controlling and directing actions, paying attention, and remembering instructions, are critical for successful functioning in preschool and elementary school. In recent years, several direct assessments of these skills have appeared, but few studies provide complete psychometric data and many are not easy to administer. We developed a direct measure of children's behavioral regulation, the Head-to-Toes Task, and report performance of participants aged 36–78 months, including a group of Spanish-speaking children, from two different sites (N = 353; N = 92). We examined construct validity, examiner reliability, sources of variation, and associations between task scores and background characteristics. Results showed that the task was valid, reliable, and demonstrated variability in children's scores. A cross-classified hierarchical growth curve analysis indicated that girls, participants assessed in English, and higher-socioeconomic status (SES) children achieved slightly higher average scores than did boys, Spanish-speaking and lower-SES children, but effect sizes were small. Older participants achieved higher scores than did younger children, and there were no effects for site. Results suggest that the Head-to-Toes Task is an informative and easy-to-administer direct assessment of children's behavioral regulation. We discuss implications for its use in early childhood settings.  相似文献

Research in the United States suggests that teachers view Black students' misbehavior as more likely to reoccur, but such research has not disentangled the effect of race from related factors. We used conjoint analysis to experimentally test the effect of multiple student characteristics on the chances of being referred for a behavior intervention program. Although preservice teacher participants were not more likely to refer Black students, they were more likely to refer students who had lower grades, lived in poverty, lived with a single mother, and had been retained. We interpret these results and highlight directions for future research and practice.  相似文献

随着我区农牧业与农牧区经济发展进入新的阶段,农产品质量安全问题己成为农牧业发展的一个主要矛盾。人们不仅要吃饱,而且要吃好的观念已是事物发展的必然趋势。吃上无公害、安全放心的蔬菜,不仅关系到西藏人民生活质量问题,而且还关系到西藏经济发展和社会稳定。本文根据西藏现代农业示范园区蔬菜良种引进与高效种植标准化示范经验,针对西藏温室、大棚蔬菜的主要污染源,提出了西藏棚室蔬菜无公害生产关键技术。  相似文献

Residual categories are those which cannot be formally represented within a given classification system. We examine the forms that residuality takes within our information systems today, and explore some silences which form around those inhabiting particular residual categories. We argue that there is significant ethical and political work to be done in exploring residuality.  相似文献

An important driver of change in work, employment and skills is European Union policy aims of sustainable economic growth and the cultivation of a green economy. Part of the latter – which is supported by increasing environmental regulation – focuses on the development of a ‘green skills agenda’, which involves the ‘greening’ of existing occupations as well as meeting the skill needs of new environmental sectors and occupations. In this paper, we compare attempts to ‘green’ work and skills through an examination of engineering apprenticeships within the German and British steel industries. We argue that efforts to ‘green’ skills are taking place at varying degrees of intensity, mostly because of variations in institutional context. The evidence we present suggests that implementation of change is much more dynamic in the context of Coordinated Market Economies such as Germany, where development is shaped by robust VET frameworks and wider processes of environmental innovation. In contrast, within Liberal Market Economies such as the UK, there are significant barriers to the vision for and investments in skills generally, as well as those necessary for greening the labour process, with an extant development paradigm that is driven by short-term benefits and a limited focus on environmental compliance.  相似文献
