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

Friendships in old age : daily encounters and emotional well-being
Get PDFHaving friends in old age is linked to higher levels of happiness and life satisfaction. Yet, we know little about what happens when older adults encounter and engage with friends throughout the day. This study examined whether older adults report a) more pleasantness, b) fewer stressful experiences, and c) better mood when they had contact with friends compared to when they had contact with other social partners or were alone. We also examined whether the closeness of friendships is associated with older adults’ daily experiences. Adults aged 65 and older (n = 313) from the Daily Experiences and Well-being Study completed an interview including information about their close social partners and their background characteristics. Then, participants reported their encounters with social partners, the pleasantness of these encounters, stressful experiences, and mood every 3 hours for 5 to 6 days using Android devices. Multilevel models revealed that encounters with friends were the most pleasant among all the encounters and were associated with fewer stressful experiences compared to encounters with spouses or family members throughout the day. Encounters with friends also were associated with increased positive mood. Further, encounters with close friends were not associated with better mood whereas encounters with friends who were not considered close were significantly associated with increased positive mood and reduced negative mood throughout the day. This work facilitates the understanding of how daily contact with friends can promote older adults’ momentary well-being.Human Development and Family Science

Friendship, racial differences and health in adulthood
Get PDFSocial relationships are associated with health across adulthood. While experiences involving friends occur in our everyday lives, we know little about the implications of friends on momentary health. Additionally, racial backgrounds may influence friendship opportunities due to structural racism, which in turn, may affect ongoing friendship patterns and health. This dissertation investigated unique effects of friends on momentary health among Black and White American adults. Study 1 examined how often Black and White adults encountered friends in real-life settings using ecological momentary assessment (EMA) technique. Moreover, I examined whether encounters with friends affect momentary mood differently for these distinct racial groups and for those who endorse more friends as important ties. Multilevel models revealed that Black adults encountered friends just as much as White adults. At times when individuals met with friends, they had increased positive mood than when they did not (within-person association), and this was only observed in White adults. Further, individuals who encountered more friends during the study period had higher positive mood than those who encountered fewer friends (between-person association), and this was observed in Black adults. Using ambulatory physiological assessments and EMA reports, Study 2 examined how encounters with friends affect individuals’ cardiovascular health as indicated by heart rate variability (HRV). Study 2 also considered the quality of encounters and explored the racial differences. Findings did not reveal a robust within-person association between encounters with friends and HRV in the overall sample. Yet, race-stratified models revealed that when Black adults met with friends, they had reduced HRV than when they did not (within-person association), but Black adults who encountered more friends during the study period had higher HRV than their same-race counterparts who encountered fewer friends (between-person association). Together, findings suggest White adults may reap immediate emotional benefits at times when they encounter friends. Black adults may not obtain immediate health benefits, but friends could still be linked to their emotional and cardiovascular health in the long run. This work contributes to the racial health disparity literature by providing a better understanding of how friends may prevent mental or cardiovascular conditions for different racial groups.

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
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
