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
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
African American community well-being: a reconsideration of the contributions of urban entrepreneurs, 1999
Full text linkThe purpose of this pilot effort was to conceptualize and examine the relationship of urban African American business to community well-being. African American entrepreneurs are seen as one aspect, albeit as often overlooked yet critical sector, of the urban African American community contributing to community welfare and social change. Two overarching methodologies were used in this study. The first general or organizing methodology included three sub-set approaches: (1) constructive typology, (2) grounded theory, and (3) historicism. The second organizing methodology is triangulation consisting of (1) participant observation, (2) survey, and (3) content analysis. African American entrepreneurs were typed into three groups: the emerging business owner, indigenous entrepreneur, and corporate purveyor. The findings indicate that historically, and in a contemporary sense, urban African American entrepreneurs have closely identified with local residents, organizations and institutions, and this relationship has contributed to the socio-economic welfare of the urban community

Achievement differences of kindergarten students from the alternative and conventional child day care delivery systems, 1988
Full text linkThe study explored whether combinations of alternative child care arrangements and sociodemographic characteristics were associated with kindergarten achievement similar to the common effects for formal preschool intervention programs. The achievement of preschool nonattenders was compared within the group by the place of child care (in- home or away from home), and among comparison groups (no preschool group, school system preschool group and non-school system preschool group). A sample of 1,456 kindergarten students was selected from among 23 schools. There were 573 students with no preschool, 11:9 from the school system preschool program and 73!: students from the non-school system preschool programs. A Child Care Questionnaire mailed to parents of the no-preschool students was used to collect information on the description and the educational dimensions of the alternative child care arrangements used by parents during the day on weekdays, the year preceding child's enrollment in kindergarten. The results of preassessment and post assessment performance on the Ready Steps Language Survey, the reading and mathematics minimum skills, Getting Ready to Read, progression status, and the California Achievement Tests were used as measures of achievement. The findings indicated that certain combinations of sociodemographic characteristics and educational dimensions of the alternative child care arrangements were associated with a high level of kindergarten achievement, and that kindergarten students with this combination of variables in the alternative child care settings demonstrated a level of achievement equal to the average for students within the same schools who attended formal preschool programs. There was no significant difference in achievement within the no-preschool group, and differences among the comparison groups were identified at preassessment and post assessment in favor of the preschool group
