Altmetrics的形成与演进:理论假说、发展阶段及学科关系     

张洋  庞进京  母丹 《图书情报工作》2021,64(23):141-150

[目的/意义] Altmetrics诞生十周年之际，对其前期发展情况进行总结，有助于推动其往积极方向发展。[方法/过程] 利用文献计量方法进行量化研究以展现Altmetrics领域的总体研究和发展情况；从术语变迁、定义等方面揭示其内涵；提出三种理论假说寻求Altmetrics存在合理性的理论支撑；划分不同阶段梳理其发展程度；分析它与其他学科的关系以明确学科属性及价值。[结果/结论] Altmetrics为计量学提供了一种新思维、新方法；开放科学假说、数字学术假说和学术传承假说符合新环境Altmetrics发展的新特点，有效支撑了Altmetrics的存在与发展；Altmetrics发展迅速，但现阶段处于发展初期，且国内外发展程度存在差异；在辨析与其密切相关学科之间关系的基础上，认为需推动Altmetrics自身学科纵深发展以及加强跨学科的合作研究。  相似文献   

Effect of Twinning on Chinese and English Vocabulary Knowledge     

Simpson W.L. Wong  Him Cheung  Mo Zheng  Xiujie Yang  Catherine McBride  Connie Suk-Han Ho  Judy Sze-Man Leung  Bonnie Wing-Yin Chow  Mary Miu Yee Waye 《Child development》2020,91(6):1886-1897

Vocabulary knowledge was tested in a native (Cantonese-Chinese) and foreign (English) language in 150 twins and 150 singletons aged 6–11 years, matched on age, gender, grade level, nonverbal intelligence, parents’ education, family income, and number of siblings and household members. The singletons clearly outperformed the twins on the native vocabulary, but this “twinning effect” was much less noticeable for the foreign vocabulary. The effect on English vocabulary was further reduced after exposure to English at home was controlled. Given that these participants learned most of their English in school rather than home, the present findings support the notion that the twinning effect is associated with increased competition for family interaction in twins compared with singletons.  相似文献

Development of a distance education assessment instrument     

Patrick J. Harrison  Farhad Saba  Bonnie J. Seeman  Gina Molise  Robert Behm  Michael D. Williams 《Educational technology research and development : ETR & D》1991,39(4):65-77

The study described in this article takes the view that distance education programs are dynamic systems with multiple constituencies. Literature on distance education programs as complex systems and on the critical constituency approach to program evaluation was used to guide the development of a questionnaire designed to assess the components of a distance education program. Instrument development was conducted in four phases using both quantitative and qualitative methods. The data from this study suggest that there are four major components of effectiveness in distance education programs: instruction, management, telecommuting, and support. Within each of these components there are from two to five subcomponents, 14 components in all, which can be used to assess distance education programs. The assessment scale which was developed measures these four components and their subcomponents.  相似文献

杆状病毒后期启动子在大肠杆菌中启动CAT基因表达的研究     

徐帆  王珣章  龙綮新  庞义  蒲蛰龙 《中山大学学报论丛》1995,(2)

以CAT基因为报道基因,探讨了杆状病毒后期启动子在大肠杆菌中启动表达CAT基因的活性。结果显示在不含多角体基因及其启动子的质粒中,具合成启动子的表达量最高,野生型多角体启动子的表达量次之,而含ⅩⅣ多角体启动子的最低;具相同CAT基因启动子的质粒中,含多角体蛋白基因及其野生型启动子者较不含者强,含合成与ⅩⅣ启动子串联组合者与单纯ⅩⅣ启动子者表达量近乎一致,但均较前者为弱。以上结果表明,杆状病毒后期启动子在大肠杆菌与在昆虫细胞中的启动表达的能力并非完全一致。  相似文献
