Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Development of a Chinese computer-assisted video instruction system
No full textThis research was designed to develop and investigate a Chinese interactive video instructional system with the use of a microcomputer. Studies in Taiwan have indicated that several major problems confront the teacher who attempts to design CAI courseware. The major difficulties are the need for Chinese input/output and the lack of authoring tools. Hence, the purpose of this project has been devoted to explore a model for using interactive video in education in Taiwan;The major task of this study was to develop the Chinese Interactive Video System (CIVS), a computer assisted video learning environment with Chinese characters display capability. Two components, a computer interface and an authoring program, were designed. An interactive video system interfaces a computer with a video cassette recorder (VCR), a slide projector, and a voice processor. The sequence of presenting the video lesson is under the control of the computer program. The computer is thus used to teach, query, remediate, or otherwise support the audio-visual lesson;The instructional options are organized through the use of editors, which are given the form of screen-displayed menus. The authoring program in the CIVS system consists of five editors: voice editor, graphics editor, character sets editor, test editor, and lesson script editor. The voice editor helps the author to organize the voice data and data-files; the Chinese Courseware Graphics Editor provides a menu with which users can compile their lesson frames; the character-sets editor allows the user to define special symbols; the test editor enables the author to create and update test items; and the lesson script editor provides the menu with which the author can build the script that forms the instructional presentation flow;The CIVS system utilizes a simple-to-follow prompting format that enables the designer to create video lessons with little or nor programming skills. Obviously, the idea and the model developed in this research represents an extension of studies regarding the implementation of computer-assisted instruction in Taiwan.</p
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
電腦輔助教學教材軟體編製之研究
No full text[[abstract]]本研究除探討「發展微電腦輔助教學課程軟體的方法與步驟。並經申實徵了解編製微
電腦輔助教學課程所可能遭遇的困難，更近而覓出解決的方法，及發展一套適合於我
國使用的中文微電腦輔助教學教材軟體。
研究的步驟首先進行文獻的探討，收集各方有關文獻，國外CAI 發展的歷史及教材軟
體編製的理論，並將軟體的發展工作，分成下列三個階段：
一、設計階段：本階段所進行的工作為選擇課程題材，選擇電腦系統及訂立學習目標
等。
二、發展階段：本階段所進行的工作為編製教學腳本，設計教學流程、拍攝教學影片
和製作電腦程式。
三、評估階段：本階段所進行的工作為：教材軟體評估及教材軟體修正。
上述三個階段的主要目的，乃在探討多元媒體電腦輔助教學的教材編製策略。
本研究所得的結論如下：
一、慎重選擇適當的題材是CAI 教材編製首要之務。
二、CAI 教材在課程內容的組織方面不易連貫。
三、CAI 教材軟體之發展工作需要集合團體的智慧。
四、現有的電腦系統中，「CAI 專用微電腦」及「個人月微電腦」各有其優點。
五、編者語言在編製中文CAI 教材時，尚未能夠完全發揮應有的功能。
六、電腦輔助教學是一新式的教學環境，電腦是一種平凡的教學媒體。
七、CAI 的教學回饋設計是CAI 課程設計最困難的部份。
八、CAI 教材的生動性是維持學習動機的重要因素。
九、單級的知識傳授，在教學運用上錄影機的畫面表達能力要優於電腦畫面的表達能
力。
十、CAI 的教材軟體製作經費昂貴。
本研究所得的建議如下：
一、考慮課程軟體的設計，應慎重選擇題材。
二、發展多元媒體的電腦輔助教學系統。
三、成立電腦輔助教學課程軟體發展中心。
四、選用電腦輔助教學系統，可採「CAI 專用電腦及個人用微電腦」雙軌並行。
五、對微電腦輔助教學應抱持平凡的態度。
六、繼續本研究進行進一步的實驗教學，以探討實際的教學效益。
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
