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
Input enhancement in classroom second language acquisition of Japanese
No full textThe study investigated the effects of input enhancement on classroom L2 acquisition using university-level beginning learners of Japanese. Two types of input enhancement—explicit explanation of target structures and textual enhancement (reading text which contained highlighted target structures)—were studied for their effect on student learning of two target structures with different levels of grammatical complexity (the gerund of adjectives and the gerund of verbs). The major part of the instruction was presented to subjects in the context of computer-assisted reading lessons. There were two experimental groups—the Explicit Grammar Group (GRAMMAR) and the Textual Enhancement Group (ENHANCE)—and one control group (CONTROL). The G subjects were given the opportunity to receive form-focused instruction (rule explanation) before the meaning-focused one (the reading lessons), but both the ENHANCE and the CONTROL subjects participated in the meaning-focused session (the reading lessons) only. However, during the reading for in-depth understanding session, only the ENHANCE subjects were exposed to text which contained highlighted target structures. The posttest was given to the subjects twice, one day after the last instruction and approximately two weeks after the last instruction. The measurement instruments used were grammaticality judgment and sentence completion. The result of data analysis revealed that in the both target structure conditions (the gerund of adjectives and the gerund of verbs), the GRAS Group did significantly better than the ENHANCE Group and the CONTROL Group on the sentence completion test, but there was no significant difference between the ONCE Group and the CONTROL Group. Also no significant difference was found among three groups on the grammaticality judgment test
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
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
Family labor supply, commuting time, and residential decisions: The case of the Tokyo Metropolitan Area
Full text linkIn this paper, I build a model of family labor supply and residential choices that explicitly incorporates the full-time or part-time work decisions of married women. The model can explain why women’s participation patterns in full-time and part-time work vary significantly in areas that are geographically close but differ in real estate prices. The model suggests that high commuting costs could be one of the main obstacles for women’s full-time employment in places like the Tokyo Metropolitan Area
A cohort analysis of male labor supply in Japan
Full text linkThis study uses repeated cross-sectional data from 1982 to 2007 to understand labor force behavior of Japanese men, focusing on the increase in non-regular employment. I find that regular employment fell significantly for recent cohorts of less-educated men. Regular employment of single men and less-educated married men responded more to the business cycle than did regular employment of highly educated married men. Cohorts who finished their schooling in the late 1990s and early 2000s experienced a severe decline in regular employment at young ages, although this phenomenon was mainly observed among single men and not among married men
