基于用户兴趣的文献个性化推荐研究     

关菲  李晓静 《教育技术导刊》2019,18(8):170-173

针对当前文献推荐中个性化程度不高等问题,提出一种对用户行为重新分配权重的度量算法。运用用户行为数据按照时间顺序重新分配权重,突出近期用户兴趣构建用户兴趣模型。通过LDA主题分布、关键词分布等方法构建学术资源模型,实现两模型间匹配,完成推荐。通过实验验证,该算法准确性达到80%,比传统等权重算法提高近20%,召回率与F值分别提升了7%和5%。研究表明,基于时间因素的用户兴趣度量算法相较于传统等权重算法具有更高的准确性,未来可进一步优化用户兴趣度量以实现精准推荐服务。  相似文献   

Determinants of Research Productivity in Spanish Academia     

Cecilia Albert  María A. Davia  Nuria Legazpe 《European Journal of Education》2016,51(4):535-549

This article aims to widen the empirical evidence about the determinants of Spanish academics’ publication productivity across fields of study. We use the Spanish Survey on Human Resources in Science and Technology addressed to Spanish resident PhDs employed in Spanish universities as academics. Productivity is measured as the total number of publications in a three‐year period. We show how personal and academic variables explain differences in productivity within universities and fields of studies and across fields of research. Female workers report lower productivity than their male counterparts, but family responsibilities do not explain this gender gap. The type of contract and tenure or rank do not seem to have any influence on productivity. Researchers seeking professional promotion rather than altruism or personal satisfaction are more productive and young scholars publish more than their older counterparts. Additionally, we find a certain research‐teaching trade‐off and some nuances in the predictors of publication productivity across birth cohorts and fields of study. Finally, international cooperation is one of the most relevant determinants of the number of publications, regardless of the birth cohort. The institutional context in the Spanish research system as regards requirements for promotion and the assessment of research outcomes may contribute to the understanding and interpretation of our results.  相似文献

New academics,new higher education contexts: a critical perspective on professional development     

Kasturi Behari-Leak 《Teaching in Higher Education》2017,22(5):485-500

New academics entering higher education are especially vulnerable if teaching in a post-colonial classroom is not foregrounded as an explicit part of their professional induction. Drawing on a study of a professional development programme for induction to teaching, this paper explicates how six new academics confront specific challenges of exclusion, marginalisation, and alienation at institutional, faculty, departmental and classroom levels. Framed by critical and social realist theory, the study uses photo voice methodology to elicit new academics' critical insights in the ‘learning to teach’ frame. The paper asserts new academics must engage in ways that make explicit the racial, gendered and class-based constraints experienced in various university spaces. While the relevance and legitimacy of current professional development programmes depends on their ability to be responsive and socially just, the study also questions whether programmes alone can challenge deep systemic constraints that are reproduced through current university structures and culture.  相似文献   

在高中新课程改革中造就新型高中教师     

方红 《黄石理工学院学报(人文社科版)》2004,21(4):93-98

普通高中新课程改革与义务教育阶段新课程改革相比，观念、内容和方式更加全新和深入，理性地思考高中教师在新课程改革中的角色定位与专业发展是普通高中课改成败的关键。新型学习方式：自主学习、合作学习和研究性学习应与高中课改内容如选修课、学分制模块式教学等紧密联系，从而建立高中教师资料提供者、情境创设者、促进迁移者、引导者、支持者、激励者等角色定位；在高中教师专业结构中，从专业知识显性化、自我反思经常化、系统化和专业知识的学术渗透方面着手将建立起新型的高中教师专业发展观。  相似文献   

University press publishing and the ecology of disciplinary fluidity: General observations     

Jean-Pierre V. M. Hérubel 《Learned Publishing》2023,36(2):164-170

Academic book and journal publishing constitutes the majority focus of university presses. Besides commercial scholarly publishers, academic scholars and researchers view the opportunities provided by university presses as important venues for the dissemination of their research. This discussion focuses on the disciplinary imperative to publish scholarship that is ever more fluid and specialized as academic disciplines continue to become further nuanced in their response to the increasing knowledge produced by humanities and social science inquiry. The focus is on university presses and not commercial scholarly presses, although constitute a significant locus of scholarly publishing. What are the general characteristics of academic specialization and university press publishing? Further, how is disciplinary fluidity, especially evolving specialization, reflected in university press book publishing nomenclature and how scholarship is tied to the intellectual preoccupations of academic specialization? Multi- and inter-disciplinarities further articulate disciplinary publishing, accelerating disciplinary fluidity. Examples from disciplinary and emerging configurations of disciplinary nomenclature utilized by university presses offers insight into specialization and publishing. Academic history publishing is used to illustrate newly emerging fluid disciplinary configurations.  相似文献
