Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
문학 교육의 교수·학습 위계성: 중학교 국어교육의 '범문학화' 현상에 대한 반성을 중심으로
No full text서울대학교 국어교육연구소에서 초·중등학교의 국어교육과 대학의 국어교육을 주제로 개최한 제15회 국제학술회의(2013. 10. 26.)에서 기획 발표한 내용을 수정·보완한 것임본 연구에서는 문학 교육의 개념을 교수․학습의 자원으로 문학 작품을 활용하는 것이라고 보았다. 그런데 초․중등학교와 대학교에서의 문학 교육은 그 목적이 같지 않다. 문학 교육의 주된 목적은 학생들의 언어 능력을 향상시키는 것이 되어야 한다. 그러나 현재의 문학 교육은 이러한 이와 같은 목적에서 벗어나 심각한 범문학화의 경향을 띠고 있다. 이러한 경향은 첫째, 교재에 문학 작품이 과도한 비중으로 실려 있고, 둘째, 교수․학습에서 문학작품 감상을 지나치게 강조하고 있다는 데서 찾아볼 수 있다.
문학 교육에서 중요한 것은 문학 교육의 가치를 이해하고 언어 교육에 있어 서 문학 작품 감상이 지니는 위상을 인식하는 것이다. 이를 위해서는 초․중등학교와 대학교에서의 문학 교육이 구별되되, 단계적으로 이어져 연쇄를 이루어야 한다. 이러한 교수․학습의 위계화를 통해 문학 교육은 학습자들로 하여금 충분한 쓰기 및 의사소통 능력을 지닌 직업인이자, 상당한 정도의 문학 지식을 갖춘 국민으로 성장할 수 있게 한다.The concept of literature education in this paper refers to using the literature works as teaching materials in class. The purpose of literature education in university and in primary or middle school is not the same. The main focus of literature education for the students in primary and middle school is to help students improve the language skill. But the current situation is that we does not meet the main requirement of the literature education for the teenagers, present a serious tendency of overemphasizing literature itself, characterized by high percentage of literary works in the teaching materials, as well as paying too much attention to literary appreciation, etc. We should specify the ultimate goal of the education of Chinese language and literature, understand the value of teaching literature, recognize the position of literary appreciation in the language learning. To differentiate literature education in the primary and middle school from those in university, realize the actual role of literature education for the junior students as the first link in the entire chain, that is to proceed to the next step smoothly after the education, then to finally take the occupation in relation to literature or any other career
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe 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
Full text linkWe 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
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
Functional characterization of nuclear receptor NR1D1 on investigation of brain metastasis
No full textBrain metastasis is a fatal recurrence of advanced cancer that affects 20% of cancer patients. Capturing comprehensive brain metastasis landscape is critical to the establishment of sufficient and effective anti-tumor strategies. Ongoing research efforts in our team aim to better understand the biology of tumor cells in human brain metastasis. Preliminary data, generated by single cell sequencing of human brain metastases highlighted a potential role of the nuclear receptor NR1D1. Indeed, NR1D1 activity seems to be correlated with proliferation, immune evasion, and metabolism of brain metastatic tumor cells. The activity of this nuclear receptor can be controlled by its ligand Hemin (HEME) and is critical in retaining control of the circadian rhythm. Our aim is to investigate the functional properties of NR1D1 itself through breast cancer cell lines. Breast cancer cell lines, SUM190, MDA-MB-231 and JIMT1 were used to study NR1D1 function and undergone multiple treatments with conditions that consisted of exposing HEME and a synthetic agonist in various incubation times while adjusting media with no FBS, essentially starving the cells from creating their own HEME. In publicly available data sets it was found that low NR1D1 expression correlated with increase of Triradylglcerols metabolism and high NR1D1 expression with increase of amino acids and peptide metabolism. In addition, our data suggests that NR1D1 activation leads to cell morphology changes and future experiments will determine whether NR1D1 influences tumor cell proliferation and immune invasion. This will assist in determining discrete phenotypes of brain metastatic tumor cells and new approaches for treatment.This research was supported from the UMGCCC American Cancer Society Institutional Research Grant – IRG-18-160-16 to Tonya J.
