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
My Life Purpose Is... : Assessment of Youth Purpose in Context
Get PDFIn the introduction to this special issue on youth purpose, the authors discuss the challenges in assessing purpose in adolescents; purpose is a concept that has more often been studied in adults but not in youth. First, the authors discuss how purpose has been defined in the literature. The authors then situate purpose in the context of a host of related constructs, such as intentional self-regulation, future orientation, goal setting, and identity. Additionally, the authors discuss the importance of accurately measuring youth purpose, as well as in what contexts the assessment of purpose is useful, such as for positive youth development researchers, as well as practitioners and evaluators of youth development programs.

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

Pathways of adolescent college graduation expectations: Individual and maternal predictors
No full textThe present study examined college graduation expectations of adolescents and young adults. A model to predict college graduation expectations of 10th grade students was developed based on Eccles' (1983) expectancy-value model. Both individual predictors (gender, school grades, self-concept of ability) and maternal predictors (maternal education; parental divorce; maternal standards, expectations, and encouragement; adolescents' perceptions of maternal advice and involvement) were included. A separate model was developed to describe and predict pathways of college graduation expectations over time, at 10th grade, at 12th grade, and at age 21. Individual predictors (early adolescent expectations, gender, school grades, self-concept of ability) and maternal predictors (maternal education, parental divorce) were examined. Data from seven waves (6th grade through age 21) of the Michigan Study of Adolescent Life Transitions (MSALT) were utilized. For the prediction of 10th grade expectations, 1352 adolescents and 784 mothers participated in at least one wave; for the prediction of expectation pathways, 868 adolescents provided data. A structural equation modeling (SEM) technique was used for the prediction of 10th grade expectations; a hierarchical linear modeling (HLM) technique was used for the prediction of pathways of expectations. The results of the SEM analyses suggested that self-concept of ability was positively related to 10th grade college graduation expectations, school grades were negatively related to expectations, and males tended to have higher expectations than girls when all variables in the model were taken into account. Maternal standards, expectations, and encouragement as well as adolescents' perceptions of maternal advice and support were positively related to expectations. The results of the HLM analyses suggested that in general, adolescents have stable pathways of college graduation expectations as they enter young adulthood. Gender, 7th grade college expectations, school grades, self-concept of ability, and maternal education level were associated with intercepts (10th grade) of college graduation expectations. The relation of gender to expectation slopes approached significance. Boys' slopes were more positive than girls' slopes. The importance of examining interindividual differences in intraindividual change is discussed
