Chinese culture through video: lines of analysis and research perspectives
No full textThis paper proposes a perspective analysis of perceptions and representations of Chinese Culture by young people with multinational backgrounds, they used the practice of video communication within a research context to promote effective practices of cross-cultural communication and the Chinese Culture, as an interpersonal cultural experience. The aim is to underline how young people of different countries perceive, understand and rebuild the Chinese Culture using videos, for example which are the most used representations cultural and values factors, and what is the level of effectiveness of the communication techniques used. Up until today, we have examined 100 of the videos made by the young producers involved in the "Looking China" project. The research approach can be included in the mixed methods (Tashakkori and Teddlie 2010). The videos were analysed individually through a grid of analyses, which focuses on the content, both on the qualitative indicators of the Chinese Culture and on the techniques used for the video communication. The results were shown and compared, using quantitative procedures that can point out to the main similarities and differences among the indicators measured. By comparison, the results show that there are interesting lines of interpersonal analysis on the experience of the Chinese Culture and of elements that could, in practical and theoretical terms, improve the practices of cross-cultural communication and help us to create spaces of knowledge on the sharing of "the other" and of the Chinese Culture through the video

No full textPh.D.Numerous investigations during the past decade have been focused on the collective motion in microbial systems and generated tremendous advances. Nevertheless, collective motion in structured microbial communities is far less understood compared to that in homogeneous microbial systems. We sought to investigate the collective behaviors of motile cells in bacterial colonies which represent perhaps the simplest form of structured microbial communities. Here, we have studied several types of bacterial collective motion observed in flagellated bacterial colonies, including the self-organization of motile rings and colony-scale unidirectional vortices. We suggest that both steric and hydrodynamic interactions contribute to the emergence of these remarkable collective motion in bacterial colonies. Our findings present unique forms of bacterial self-organization that may influence population structure and material distribution in bacterial communities. Moreover, our work may provide us a better understanding of active matter behaviors in complex fluids or gels.在過去的幾十年中，許多工作致力於研究微生物的集體運動，並取得了巨大進展。然而，結構化群落環境中的微生物集體運動還遠沒有被了解。我們試圖研究運動的細菌菌落中的集體行為，細菌菌落可能代表了最簡單的結構化微生物群落。在這篇論文中，我們研究了在細菌菌落中觀察到的幾種細菌集體運動模式，包括自組織在菌落邊緣形成運動環和菌落尺度的渦旋。我們認為，空間和流體相互作用都有助於細菌菌落中這些有趣的集體運動的出現。我們的發現提出了細菌自組織的獨特形式，可能會影響細菌群落中的種群結構和物質分佈。此外，我們的工作可能使我們對複雜流體或凝膠中活性物質的行為有更好的了解。Xu, Haoran = 細菌菌落中的集群運動 / 徐浩然.Thesis Ph.D. Chinese University of Hong Kong 2020.Includes bibliographical references (leaves 71-82).Abstracts also in Chinese.Title from PDF title page (viewed on March 28, 2022).Xu, Haoran = Xi jun jun luo zhong de ji qun yun dong / Xu Haoran
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
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
