This paper presents a statistical analysis of the relationship between three science indicators applied in earlier bibliometric studies, namely research leadership based on corresponding authorship, international collaboration using international co-authorship data, and field-normalized citation impact. Indicators at the level of countries are extracted from the SIR database created by SCImago Research Group from publication records indexed for Elsevier’s Scopus. The relationship between authorship and citation-based indicators is found to be complex, as it reflects a country’s phase of scientific development and the coverage policy of the database. Moreover, one should distinguish a genuine leadership effect from a purely statistical effect due to fractional counting. Further analyses at the level of institutions and qualitative validation studies are recommended.  相似文献

ABSTRACT

As e-resources become more ubiquitous, and the technologies available to access them more sophisticated, libraries have greater opportunities to reach out to global users. However, this same distance means that some users never even set foot in a physical library. This case study will describe how one large academic library started a business, economics, and marketing library online instruction pilot for global users in an effort to replicate library instruction offered at the home institution. Librarians assessed global library use and research needs; prepared unique lesson plans for each global site; and created digital learning objects using synchronous and asynchronous methods to establish an instruction strategy for Business and Economics courses. The goal was to test instruction practices and develop an online instruction template that would be replicable and sustainable for library instruction in other subject areas in New York University Libraries and other institutions.  相似文献

The aim of this study was to analyse the effect of stimulus change timing on reaction response time parameters, horizontal velocity of the centre of mass (CM) and precision during offensive actions in fencing. Twelve fencers from the Spanish National Foil Team were included in the study. Two 500 Hz force plates were used to register the horizontal component of the reaction force while a 3D video camera set at 250 Hz recorded the spatial position of 11 body markers and a projector connected to a programmed stopwatch projected a moving target (stimulus) on a screen. When the circle (target) appeared in the centre of the plastron, fencers had to execute a step-forward-lunge as fast as possible, trying to touch the circle with the tip of the foil. During the lunge, the position of the target could randomly shift or not to three different positions. The stimulus change was performed randomly at four different times with a progressive delay. The results show that target changes did not have any effect when they occurred at the beginning of the movement sequence. However, when the target change was delayed, reaction and movement times increased and the technical execution of the lunge changed, leading to more errors.  相似文献

分析当前对外汉语口语课所肩负的任务,以及其中所存在的问题。某些口语课依然存在以讲授语言点为重点,而不是侧重语言技能的训练。教学进度与练习时间冲突。在语言环境不够真实的情况下,教学方法又太过传统。在教学实践中,各任课教师集体备课,协调词汇语法教学任务。以及走出课堂,充分利用学校和社会语言环境等方法对提高口语课的实效都很有帮助。  相似文献

This study examines ethnic, national, familial, and religious identity and well‐being of 632 Roma minority and 589 majority adolescents (age: = 15.98 years, SD = 1.34) in Bulgaria, the Czech Republic, Kosovo, and Romania. Results indicated that Roma showed lower endorsement of national identity but stronger religious identity than their majority counterparts. Path models showed positive associations of familial and religious identities with well‐being, whereas Roma identity was negatively associated with well‐being, particularly for Roma in Bulgaria and Kosovo (countries with a less active policy toward improving conditions of Roma). In the latter countries, Roma ethnic identity is less relevant and weakly associated with psychological well‐being of youth.  相似文献

Although our students correctly define the terms p‐value, Type I and Type II errors, they sometimes misinterpret results from real data. In this work we present an assignment intended to clear up these misconceptions.  相似文献
