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
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
Comparisons of primary somatosensory and primary motor cortex neuronal activities in sensory processing and movement execution of the rat
No full text初級體感覺皮質(Primary somatosensory cortex, SI)和初級運動皮質(Primary motor cortex, MI)分別為身體感覺和主動運動之核心，在麻醉狀態中具有functional segregation的特性。本研究為探討SI和MI在清醒動物中是否維持分工的特性，以多頻道微電極同時記錄同一隻大鼠的SI及MI，比較兩區的神經元在前掌受到輕觸(風吹刺激)和傷害性(雷射熱)刺激時的反應，以及在執行主動運動(步行和抓取)時的活動變化。麻醉時SI對於感覺刺激產生明顯的興奮，MI則缺乏反應，然而在清醒狀態中兩者皆對感覺刺激出現興奮，反應趨於相似；在主動運動方面，SI和MI神經元的活動皆與動作過程相關。這些證據顯示，清醒大鼠的SI及MI互有參與感覺認知和自主運動的控制，而且兩者的功能息息相關，其分工情形與麻醉狀態不盡相同。Primary somatosensory cortex (SI) and primary motor cortex (MI) have been thought of as the most critical centers for perception and voluntary motor control respectively. To explore the hypothesis of segregation of functions in conscious animal, we recorded directly multiple single-units in the forelimb region of SI and MI in the same rat, SI and MI neuronal activities were compared during tactile (air puffs) and noxious (laser heat) stimulation of the glabrous skin of the forepaw, and during voluntary movement of the forelimb (walking and grasping). Our data showed that SI neurons had brisk response to sensory stimuli comparing with MI under anesthetized status, while these two areas tends to share similar response in the conscious state. Also, both SI and MI had significant correlative neuronal activities in the process of voluntary movement. These data indicate that MI and SI have well-defined functional segregation under anesthesia, yet work closely together in sensorimotor integration in the conscious state.摘要 2

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
An Analysis of <i>Judge Lin</i>
No full textBiography of Lin Wen Zhong Gong has another way to call, that is Judge Lin. The leading character is Lin Ze-Xu. This book is based on functionary experience of Lin Ze-Xu, with the captivating plots of court case, helping by highly skilled military attach\uc3\ua9s and chivalrous knights, and the history facts of Opium War. It makes Lin Ze-Xu\ue2s Confucian temperament and tragic mood more, also contrasts with author\ue2s sorrow and furiousness for the politics at the time. History, court case, martial arts\ue2\ua6\ue2\ua6etc. are essence of this book and it broadens the way of this writing style.
The topic of the thesis is \ue2An Analysis of Judge Lin\ue2. The following thesis will be divided into six different chapters. The introduction is Chapter one of the thesis, which is including researching motive and purpose, literature review of predecessors, researching version by existing information, raising questions, choosing research methods and arranging chapters. In chapter Two, I discuss the study of characters of Lin Ze-Xu, also makes a deep analysis of author\u27s purpose of writing him. In chapter Three, I analyze supporting actors and actress. Meanwhile, I illustrate author\u27s purpose of writing supporting actress because the author had different manner to describe supporting actress. Moving to the Chapter Four, I mainly focus on the plots of Judge Lin, and organize cases of Lin Ze-Xu and his subordinates to understand features of cases. In Chapter Five, I represent the causes of Opium War. China and England had difference of opinions of opium. Therefore, it is easier to comprehend what the author\u27s purpose is. In the last chapter I summarize the main points of the preceding chapters and confirm particularity of Judge Lin
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
