Conceptual metaphors in Barack Obama’s 2009 inaugural speech
Get PDFMetaphors are a key element in politics, framing abstract ideas in concrete domains familiar to people. The 2009 inaugural address given by Barack Obama, at a time of national crisis, becomes an inherent case to study the systematic use of metaphors. This study aims to reveal how conceptual metaphor structures provide coherence for Obama’s rhetoric and enhance the persuasive power of metaphor networks within his speech. Drawing from Conceptual Metaphor Theory and critical metaphor analysis, the study applies MIP to the entire inaugural address. Metaphors were coded, categorized, and cross-validated by the researcher to ensure reliability. The analysis showed dominant metaphorical domains of journey, construction, family, war, renewal, and light that form coherent networks of collective struggle, unity, and national renewal. While it supports previous findings, it suggests that the metaphor phenomena should be viewed as interrelated rather than separated into categories. The study presents the power of metaphor networks for the president’s rhetoric, advances metaphor analysis in political communication, and posits wider applications for understanding leadership rhetoric
A Study on the Perceived Effectiveness of YouTube in Listening Skills among English Majors at a Vietnamese Public University
No full textIn the world of digitalization, YouTube has become an exceptional channel for language learners, providing authentic audiovisual input to enhance listening skills and engagement. This study involves English-major students in a Vietnamese college, looking into students' attitudes toward YouTube and their usage of it in English listening-skill development. The research adopted a quantitative cross-sectional survey design and collected data through a structured questionnaire administered to 140 first- and second-year English majors at HUIT. The findings indicate that most students hold positive attitudes towards YouTube, viewing it as an entertaining, accessible, and effective platform for enhancing listening comprehension. There was a statistically significant positive correlation between the frequency of YouTube usage and the perceived effectiveness of the platform among students. Moreover, students continued to access YouTube content outside class hours for entertainment and learning, with many expressing that they perceive improvements in other language skills besides listening. Underlying these discoveries is the potential of YouTube as a secondary language-learning tool, especially in encouraging learner autonomy and sustained engagement in listening in English as a Foreign Language (EFL) context. These findings highlight the possibility for YouTube to foster learner autonomy and sustained engagement in EFL listening and bring about practical challenges to those language teachers and curriculum developers integrating digital technologies into English teaching
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
