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

Sleep Quality and the Content of Autobiographical Memory: Differential Associations by Memory Valence and Temporality
Get PDFAlthough sleep after learning has been associated with memory for emotional stimuli in the laboratory, research has not yet been conducted to examine relations between sleep and the subjective experience of autobiographical memories. The present study was conducted to determine whether sleep quality was associated with the subjective experience of autobiographical memory and whether the demonstrated associations were mediated by depression. One hundred twenty-one female university students reported on their most significant positive and negative memories as well as memories of positive and negative events that occurred during the previous 2 weeks; they also completed measures of sleep quality and depression. The results revealed that participants with poor sleep quality reported events that occurred more frequently relative to participants with good sleep quality. The former group was also less confident that the reported memories were not influenced by pictures or conversations with others relative to the latter. In addition, participants with poor sleep quality thought more about their negative experiences and used more negative emotion words when describing recent negative events relative to participants with good sleep quality. Depressive symptoms mediated the relation between sleep quality and (a) frequency of thought about negative events and (b) the percent of negative emotion words used when discussing recent positive events. Given that the process of evaluating and making meaning of past emotional events is associated with mental health, future research should examine whether sleep interventions might serve to improve sleep quality, reduce indices of depression, and facilitate the processing of negative events
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

Sleep in College Club Athletes: Patterns, Correlates, and Comparisons with College Non-Athletes
Get PDFSufficient sleep is essential for maintaining physical and emotional well-being, and both quantity and quality of sleep are related to numerous well-being and functional outcomes. Among college students, poor sleep has been related to poorer mental health and academic performance. Collegiate athletes are a subgroup of college students that may face additional challenges in maintaining ample and good quality sleep due to the time demands, psychological pressures, and rigid schedules associated with participation in college sports. Sleeping well may be even more critical for college athletes relative to the general undergraduate population, as the success of college athletes on the field may greatly rely on the restorative benefits of sleep to both their physical and psychological functioning. However, no known studies have examined sleep or well-being outcomes in college club athletes, who compete at a lower level than NCAA-level athletes but may still experience many of the same stressors and sleep problems. In two studies, the present dissertation examined both objective (i.e., wrist actigraphy) and subjective sleep parameters and their correlates in college club athletes (Study 1) and compared subjective sleep variables and academic performance between college club athletes and college non-athletes (Study 2). Club athletes and non-athletes did not differ in their sleep profiles or academic performance, but club athletes reported feeling less stressed than non-athletes. For club athletes, important relationships were found between both objective and subjective sleep measures and next day affect. Notably, athletes reported lower negative affect on days after which they had above average sleep efficiency and self-reported sleep quality the previous night, as well as higher positive affect after nights of better self-reported sleep. Additionally, for club athletes, better sleep hygiene was related to both higher daily and global subjective sleep quality and to lower reported insomnia severity. Sleep profiles of college club athletes are discussed in comparison to previous findings for college students, college athletes, and elite athletes. Implications for the affective and functional consequences of poor sleep in club athletes are also discussed
