发文周期过长是目前我国科技期刊界一个普遍存在的问题,增强编辑的时效意识是解决此问题的有效途径。科技期刊编辑的时效意识是时间意识和效率意识的有机统一,二者相辅相成,忽视任一方面都不会取得最佳效果。在工作过程中,编辑主体不但要牢固树立时效意识,而且还要注意克服短时效意识及长时效意识带来的不利影响。 相似文献

人类历史的发展既是一个客观的和有规律的自然历史过程。也是一个自为的合目的的主体自觉选择过程。马克思创立的唯物史观克服了以往历史观的局限。实现了科学原则和价值原则的统一。但人类历史发展过程中价值的实现并非是一帆风顺的。是一个付出代价和扬弃代价的辩证过程。需要人们权衡利弊进行正确的价值选择。 相似文献

This article outlines an interval estimation procedure that can be used in a 3-level setting to evaluate the proportion of outcome variance attributable to the second level of clustering. The method is useful for examining the necessity of including a possibly omitted intermediate level of nesting in analyses of data from a multilevel study, and represents an informative addendum to current statistical tests of second-level variance. The approach is developed within the framework of latent variable modeling and can be used as an aid in the process of choosing between 2-level and 3-level models in a hierarchical design. The discussed procedure is illustrated with an empirical example. 相似文献

Most distance learning institutions collect vast amounts of learning data. Making sense of this ‘Big Data’ can be a challenge, in particular when data are stored at different data warehouses and require advanced statistical skills to interpret complex patterns of data. As a leading institute on learning analytics, the Open University UK instigated in 2012 a Data Wrangling initiative. This provided every Faculty with a dedicated academic with expertise data analysis and whose task is to provide strategic, pedagogical and sense-making advice to staff and senior management. Given substantial changes within the OU (e.g. new Faculty structure, real-time dashboards, two large-scale adoptions of predictive analytics approaches, increased reliance on analytics), this embedded case study provides an in-depth review of lessons learned of five years of data wrangling. We will elaborate on the design of the new structure, its strengths and potential weaknesses, and affordances to be adopted by other institutions. 相似文献

The purpose of this study is to explore key factors that impact the college transition of aspiring underrepresented minority
students in the biomedical and behavioral sciences, in comparison with White, Asian students and non-science minority students.
We examined successful management of the academic environment and sense of belonging during the first college year. Longitudinal
data were derived from the Higher Education Research Institute’s (HERI) 2004 Cooperative Institutional Research Program (CIRP)
Freshman Survey and the 2005 Your First College Year (YFCY) Survey. Using a reformulation of the integration model (Nora,
Barlow, and Crisp, 2005), we find concerns about college financing, negotiating family support and responsibility, and campus
racial dynamics (perceived and behavioral) affect student adjustment and sense of integration in the first year.

Informal Science Learning (ISL) is a policy narrative of interest in the United Kingdom and abroad. This paper explores how a group of English secondary school science teachers, enacted ISL science clubs through employing the Periodic Table of Videos. It examines how these teachers ‘battled’ to enact ISL policy in performative conditions at the micro-scale, and how this battle reflected macro-scale epistemological and political considerations. Data from the study suggests that for some, ISL was low stakes as it was seen to have negligible impact upon performance data. As a result, there was some resistance towards enacting ISL and conflict between the formal and informal curriculum processes. Nonetheless, analysis indicates that the informants highly valued ISL despite the requirement for them to justify it over more formal and ‘effective’ approaches to learning science. 相似文献
