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
The Use of Chinese Yang/Qi-Invigorating Tonic Botanical Drugs/Herbal Formulations in Ameliorating Chronic Kidney Disease by Enhancing Mitochondrial Function
No full textBackground: Chronic kidney disease (CKD) is a leading cause of morbidity and mortality. Mitochondrial dysfunction has been implicated as a key factor in the development of CKD. According to traditional Chinese medicine (TCM) theory, many Chinese Yang/Qi-invigorating botanical drugs/herbal formulations have been shown to produce promising outcomes in the clinical management of CKD. Experimental studies have indicated that the health-promoting action of Yang/Qi invigoration in TCM is related to the up-regulation of mitochondrial energy generation and antioxidant status. Objective: In this review, we aim to test whether Chinese Yang/Qi-invigorating tonic botanical drugs/herbal formulations can provide medical benefits in CKD and its complications. And we also explore the possible involvement of mitochondrial-associated signaling pathway underlying the beneficial effects of Yang/Qi invigoration in TCM. Methods: A systematic search of “PubMed”, “China National Knowledge Infrastructure (CNKI)” and “Google Scholar” was carried out to collect all the available articles in English or Chinese related to Chinese Yang/Qi-invigorating tonic botanical drugs/herbal formulations and their effects on mitochondrial function and chronic kidney disease. Result and Discussion: The relationship between the progression of CKD and mitochondrial function is discussed. The effects of Chinese Yang/Qi-invigorating tonic botanical drugs/herbal formulations and their active ingredients, including phytosterols/triterpenes, flavonoids, and dibenzocyclooctadiene lignans, on CKD and related alterations in mitochondrial signaling pathways are also presented in this review. In the future, exploration of the possible beneficial effects and clinical studies of more Yang- and Qi-invigorating botanical drugs/herbal formulations in the prevention and/or/treatment of CKD and the molecular mechanisms relating to the enhancement of mitochondrial functions warrants further investigation. Conclusion: Given the critical role of mitochondrial function in safeguarding renal functional integrity, the enhancement of mitochondrial energy metabolism and antioxidant status in kidney tissue is likely involved in renal protection. Future studies on the biochemical and chemical basis underlying the effects of Chinese Yang/Qi-invigorating tonic botanical drugs/herbal formulations from a mitochondrial perspective will hopefully provide novel insights into the rational development of new drugs for the prevention and/or treatment of CKD.</p
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
Influence of spouse support and marital satisfaction on the relationship between job satisfaction and teaching abilities of female teachers at universities in Guangxi, China / Yang Qi
No full textAlthough teachers' job satisfaction has been studied for a long time, there has been little
past research on the job satisfaction of married female university teachers in their social
identities, and even less research on teachers' teaching abilities in specific contexts.
Therefore, this study aims to examine whether the marital satisfaction and spouse support
of married female university teachers have a mediating effect on their job satisfaction and
teaching ability. The author conducted the research in a quantitative way, theoretical
validity and reliability of variable scales were established in the study context prior to
data collection, and then a total of 556 married female teachers from 8 universities in
Guangxi, China participated in the questionnaire collection of this study. Then, the author
uses descriptive analysis, multiple linear analysis and Module 4 of PROCESS (multimediators)
to further analyse the research data. The results show that female university
teachers' job satisfaction (Mean=3.6473, SD=.65561) and marital satisfaction
(Mean=3.7286, SD=.70586) are both in high satisfaction level, and also their satisfaction
performance is often evident. At the same time, female teachers perform well in terms of
the current state of perceived spouse support (Mean=3.7300, SD=.68724), presenting the
main outcome dimension of presence and showing more recognition and existential
satisfaction with the implementation and current state of their own teaching abilities (Mean=3.8015, SD=.64941). Furthermore, the research results show that the job
satisfaction of married female teachers has a significant impact on teachers' marital
satisfaction, spouse support and teaching ability, which means when teachers' job
satisfaction is improved, the other three aspects will also be followed by a positive
development. In the verification of mediating variables, it shows that the marital
satisfaction of married female university teachers has a significant mediating effect on
the relationship between job satisfaction and teaching ability of teachers; while their
spouse support is not significant mediating effect on the relationship between job
satisfaction and teaching ability. In a sense, therefore, this study has deepened and
clarified the basic characteristics about teachers’ teaching abilities, includes specific
dimensions of presentation of teaching abilities. At the same time, the single-gender
specific study also prepares the ground for future comparative studies between male and
female teachers on the relevant dimensions. It is therefore, which hoped that this study
will enable universities and academic departments to pay attention to the situation of
teachers and to optimise policies and support for teachers in terms of working hours,
career development and work-life balance with gender detail perspective. It is also hoped
that female teachers themselves will pay attention to the long-term significance of their
married life, as well as to their own life satisfaction and well-being, in order to be better
prepared to demonstrate their teaching abilities and to ensure the quality of their teaching
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
