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
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
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
Detritivory in the Mangrove Sesarmid Crab Parasesarma Erythodactyla
No full textSesarmid crabs have important ecological roles in the mangroves of the Indo-west-Pacific biogeographic region. By processing large amount of leaf litter, these crabs retain organic matter in the mangroves, increase the rate of mineralisation, and fuel additional trophic links with the processed material. However, the dietary composition of the mangrove sesarmids is still a controversy. Gut content analyses suggest a dominant contribution of mangrove leaf litter in the crab diet but stable isotope data seem to support the assimilation of organic matter derived from the microphytobenthos but not mangrove litter. In addition, ability of the sesarmid crabs to obtain sufficient nutrition from mangrove litter, which is rich in structural carbon (cellulose) but poor in other nutrients such as nitrogen, has been questioned. The over-arching goal of this thesis was to fill these gaps of knowledge in detritivory of the mangrove sesarmids, using Parasesarma erythodactyla (Hess, 1865), the dominant shredder in sub-tropical Australian mangroves, as an animal model.Thesis (PhD Doctorate)Doctor of Philosophy (PhD)Griffith School of EnvironmentScience, Environment, Engineering and TechnologyFull Tex
WAR/ PEACE JOURNALISM APPROACH IN VIETNAMESE ONLINE MEDIA COVERAGE OF SOUTH CHINA SEA DISPUTE : An analysis of Mediated Vietnamese Public Diplomacy Messages
No full textThis research aims at examining the Vietnamese online media’s framing of conflict, thereby highlighting the outstanding characteristics of peace journalism and war journalism frames available in the media of an Asian peripheral country when it covers conflicts with other core, more powerful nations. The study is inspired from an overarching hypothesis of a possible junction between peace journalism and public diplomacy as relevant theories have it that they are basically identical in one sense: both representing a form of message which carries the note of peace-rebuilding, solution-orientated and mutual understanding in the war context. That message is delivered through media to reach out the foreign publics, not only to gain benefits for national interests but also to point out a solution for peace and offer an opportunity to conflict-resolution talks. The events chosen for study are media analysis following two attacks in late May and early June, 2011 against two Vietnamese oil exploration vessels in the South China Sea in which China was the accused. Basing on the theories of peace journalism, public diplomacy and world system theory, the research hypothesized that Vietnamese online media’s framing of China throughout seven months May 1st to November 30th, 2011 is inclined towards peace journalism. Two research techniques were employed: Quantitative Content Analysis to find out the dominant frame of the Vietnamese online media when covering the two clashes between Vietnamese and Chinese ships; and Qualitative Critical Discourse Analysis to further examine what messages the media aspire to send to foreign publics and how these messages are crafted. Findings from the content analysis rejects the main hypothesis, showing that the Vietnamese online media still opted for the war journalism frame even though theoretical and empirical evidence confirms Vietnam’s soft, assuaging and non-provocative approach in its public diplomacy with China. CDA results however highlighted the characteristics of the Vietnamese online media’s war frame: very tactful and implicit. The negative China presentation and positive self-presentation of Vietnam cannot be clearly seen through the use of victimizing, dehumanizing and emotionalizing language, but through implications and presuppositions hidden in the sentences. The implied messages that the Vietnamese online media want to send out the foreign publics portray China as a perverse bully neighbor and a two-faced partner, defying international law and breaking regional peace. Meanwhile, Vietnam is portrayed as a tolerant victim of China – its own friend and as a noble, forgiving friend of China. These messages are presented in the media by a very flexible, diplomatic and reconciliatory language so as to create an enemy scene with China. The study confirms the value and applicability of the theories selected and findings from previous studies. It also inspires future studies on expanding public diplomacy and peace journalism theories to make it more applicable to media of similar state structure or those in Asia./
Developing the speaking competences of primary school students in english as a foreign through drama activities
No full textEnglisch wurde 1986 in Vietnam eingeführt. Mehr als 40 Jahre später finden es Vietnamesen immer noch schwierig diese Sprache zu sprechen. Zur Verbesserungen der Fertigkeit Sprechen entwickelte die Regierung eine Reihe neuer Lehrbücher auf der Grundlage des Kommunikativen Sprachunterricht Ansatzes (CLT). CLT ist eine lernerzentrierte Interaktions- und Lehrmethode, die auf authentischen Materialien basiert. Die hier betrachtete CLT-Methode ist Theater. In Theaterstudien zeigten Lernende aus der ganzen Welt eine enorme Verbesserung ihres mündlichen Ausdrucks. Jedoch fand CLT bisher wenig Erfolg in Vietnam (Ellis 1994). Die Gründe, warum CLT sich nicht erfolgreich in Vietnam etabliert hat, sind unter anderem die traditionellen grammatik-basierten Prüfungen, der Einfluss des Konfuzianismus auf die vietnamesische Kultur, die Zahl der Schüler pro Klasse und die seltene Anwendung der englischen Sprache im täglichen Leben. Um diese Herausforderungen zu überwinden, wurde im vorliegenden Dissertationsprojekt eine Experimentalstudie entworfen, mit dem Ziel die Fertigkeit Sprechen bei Schülern zu verbessern. Hierbei wurden Theateraktivitäten durchgeführt, um die Vorteile des CLT zu nutzen, gleichzeitig wurden die oben genannten Effekte minimiert. In dieser experimentellen Studie wurde per Zufallsprinzip eine Gruppe Viertklässler in einer ländlichen Grundschule in Vietnam als Kontroll- und Versuchsgruppe gewählt. Vor Beginn des Experiments wurde bei beiden Gruppen mit Hilfe von Fragebögen die Motivationniveaus und Einstellung zum Fremdspracherwerb ermittelt. Auch die Sprechkompetenz wurde getestet, um das Niveau der Versuchspersonen zu evaluieren. Die Versuchsgruppe folgte einem auf Theateraktivitäten beruhendem lernerzentriertem Lehrplan, während die Kontrollgruppe dem regulärem Englischunterricht folgte. Nach den vier Monaten des Experiments wurden wieder durch Fragebögen die Niveaus der Motivation und Einstellungen der Schüler beurteilt. Ferner wurden erneut Sprechkompetenztests bei beiden Gruppen durchgeführt, um die Entwicklung der Gesamtsprachkompetenz zu testen. Die Schüler wurden zu Beginn der Studie und am Ende der Studie beurteilt. Gepaarte t-Tests wurden durchgeführt, um zu bestimmen, ob es statistisch signifikante Unterschiede zu verschiedenen Zeitpunkten oder zwischen den beiden Gruppen gab. Als Ergebnis des Theaterunterrichtplans zeigt die Versuchsgruppe eine statistisch signifikante Steigerung in allen Parametern der Sprechkompetenz im Vergleich zu der Kontrollgruppe, während die Kontrollgruppe Steigerungen in einer begrenzten Anzahl von Bereichen wie der Grammatik zeigte.
Diese Ergebnisse unterscheiden sich von der Literatur, laut derer die CLT nicht in Vietnam angewendet werden kann (Ellis 1994) und ist eine vielversprechende Perspektive für übergeordnete Erzieher und politische Entscheidungsträger.English was first introduced as a taught foreign language in Vietnam in 1986, yet more than 40 years later the Vietnamese people still find it difficult to speak the language. To improve the students’ proficiency in speaking English, the Vietnamese government developed a series of new textbooks based on the Communicative Language Teaching (CLT) approach. CLT is a learner-centred, interaction-driven and authentic materials-driven teaching approach. The CLT method of interest in this study is the teaching of drama. Learners have shown significant improvements in their speaking-related parameters through drama studies all over the world. However, the CLT approach has found little success in Vietnam in the past (Ellis 1994). The reasons why CLT has failed to be successfully applied in Vietnam may be due to a number of reasons, such as the influence of Confucianism on Vietnamese culture, the traditional grammar-based examination system, the number of students per class, and the infrequent use of the English language in daily life. To overcome these challenges, this research project is designed as an experimental study that aspires to increase the students' competency in speaking English by using drama activities in order to employ the advantages of CLT, while at the same time minimizing the effects of the above-mentioned factors. In this study, a group of Grade 4 students in a rural primary school in Vietnam was randomly assigned to a control or experimental group. Before starting the experiment, both groups were administered questionnaires to measure their initial levels of motivation and their attitudes to learning a foreign language. They were also tested to evaluate their speech competence levels. The research group followed a learner-centred syllabus, based on drama activities; meanwhile, the control group continued with their daily routine in the English language class. After the four months of the experiment, both groups were administered post-experiment questionnaires to check their levels of motivation and their attitudes. Post-experiment speech competence tests were given to both groups to again test the development of their total speaking competences. As a result of the drama lesson plans, the experimental group showed statistically significant increases in all measures of their speaking competences in comparison to the control group, while the control group showed increases in a limited number of areas such as grammar. The findings of this study differ from the literature, which has found that a CLT approach cannot be applied in Vietnam (Ellis 1994), and are promising from the perspectives of parents, educators and policymakers
