    The 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” 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

    We 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

With 75-95% of adults failing to engage in enough physical activity to reap the health benefits, it is crucial to direct efforts towards understanding why some individuals initiate and maintain a physical activity routine while others do not. Purpose: The purpose of the present study was to conceptualize ‘personality’ in the context of exercise and explore how individual differences influence future exercise behavior. Moreover, it is of particular interest whether a persistent exercise routine may evoke positive, personality development (e.g., improve Emotional Stability via trait Anxiety reductions and strengthened Resilience). Methods: This project includes data, analysis, and interpretation from two distinct studies. The first study was integrated into an academic course, where undergraduate students (N=264) enrolled in the course participated in all aspects of the study via lab activities or assignments. They completed an online survey to assess descriptive, educational, demographic, and retrospective exercise behavior as well as various individual differences (i.e., Big Five Personality Constructs, Resilience, Exercise Autonomy, Affective Associations towards Exercise), and completed health-related fitness testing and cognitive testing (i.e., to assess implicit attitudes towards exercise & cognitive control). Finally, they completed a self-report 7-day exercise journal while a subset of students simultaneously wore accelerometers. For the second study, previously sedentary, middle-aged adults (N=29) completed a progressive resistance exercise training (RET) intervention on 3 d・wk-1 for 10-weeks. Prior to beginning and following the RET intervention, participants’ psychological traits (i.e., construct Neuroticism, trait facet Resilience, and trait facet Anxiety) were assessed. Results: While numerous relationships were observed between personality and future exercise behavior, Exercise Autonomy had the greatest influence on future exercise Frequency, Duration, and Intensity. Moreover, while trait Extraversion has been touted as an important predictor of exercise behavior in previous literature, this study did not observe any relation between Extraversion and exercise behaviors (past or future), except when considering whether someone typically exercises alone or with a group. In addition, a significant decrease in trait Anxiety, a facet of Emotional Stability, was observed following the 10-week RET intervention. Conclusion: ‘Personality’ can be conceptualized as consistent patterns in our thoughts, feelings, and behaviors. This study, considering multiple theoretical foundations, attempted to address how cognitive ability (i.e., cognitive control), affective associations (i.e., feelings/attitudes about exercise), personality constructs (e.g., Neuroticism, Extraversion), self-regulation (i.e., resilience, autonomy) and past exercise behavior explained future exercise behavior. Numerous psychological determinants were associated with past behavior, but the most important driver(s) of future behavior are past behavior and the degree of perceived Exercise Autonomy. That is, those who are personally fulfilled by exercise (e.g., brings pleasure and enjoyment, identify as an exerciser) are more likely to engage in exercise more frequently, for longer durations, and with greater intensity. Finally, the observed reduction in trait Anxiety for middle-age adults provides promising evidence of the potential for personality development through regular exercise

    Individual differences in affect and vagal tone in response to moderate- and high-intensity interval exercise: A preliminary model

    Background. Evidence suggests regular exercise, amongst other healthy lifestyle choices, promotes enhanced quality of life and longevity. However, the majority of adults (>85%) do not meet the requirements suggested by the U.S. Physical Activity Guidelines, thus missing out on potential benefits. Some researchers have proposed the lack of continued exercise behavior is a result of negative affective responses associated with exercising, and suggest individuals must feel good (e.g., experience pleasure) during and following (e.g., enjoyment) exercise in order to increase the likelihood of future engagement. Promising evidence to support the application of the exercise-affect-adherence relationship has emerged. However, a conundrum exists: high-intensity training programs have gained, and are maintaining, popularity, even though these often result in negative feeling states, which should decrease likelihood of adherence to such regimens. It is possible some individuals are more suited for high-intensity exercise; that is, they are predisposed to experience more pleasure or less displeasure during high-intensity exercise leading to a desire for continued future engagement. Purpose. To examine affective and vagal tone reactivity to and recovery from an acute bout of moderate-intensity (MIIE) and high-intensity interval exercise (HIIE), and to consider how individual differences (e.g., personality, biological dispositions) influence these responses. Methods. Participants (N= 25, 13 females, 23.3±4.0 yrs, BMI= 25.7±4.1 kg·m-2, HRrest= 68.12±11.66 b·min-1, VO2peak= 41.57±9.42 ml·kg-1·min-1) completed 4 sessions at the same time of day on different days, with at least 24-hours between each session. Refraining from exercise (24-hours prior), caffeine (8-hours prior), and alcohol (12-hours prior), participants completed a baseline session to record resting affect and cardiac vagal tone. Personality, regulation-style, and emotional complaints (i.e., Anxiety, Depression, and Stress) were also assessed via questionnaire. Participants completed a graded exercise test on a stationary bike (cycle ramp protocol 25 W·min-1) to volitional exhaustion during the second session, where peak oxygen consumption, peak heart rate, and oxygen consumption at ventilatory threshold (VT) were determined. Based on individual workload at VT, a relative high- (5% below relative load at VT) and moderate-intensity (25% below relative load at VT) load was determined for sessions 3 and 4. Participants then completed a high- (HIIE) and moderate-intensity interval exercise (MIIE) session (5 intervals of 3-min of exercise to 1-min of rest) where affect and vagal tone were recorded prior to, during, and up to 30-minutes post exercise. The HIIE and MIIE sessions were randomized and counterbalanced in order to control for pre-exercise states. In addition, participants were blinded to the condition intensities. Results. Participants reported more negative feeling states and experienced greater vagal tone withdrawal during the HIIE session compared to the MIIE session, but these states recovered similarly as early as 5-minutes post-exercise. In addition, individual characteristics (i.e., fitness), traits (e.g., Extraversion, Conscientiousness, Neuroticism), emotional complaints (i.e., Depression, Anxiety, and Stress), and biological dispositions (e.g., tonic vagal tone) provided predictive variance on affective reactivity (i.e., valence) during the HIIE session. This suggests some individuals are predisposed to respond more positively to high-intensity exercise. Conclusions. These findings indicate that some individuals may thrive (i.e., initiate and adhere) in a high-intensity exercise program, while others are more likely to experience displeasure and potentially drop-out. In order to optimize exercise programming, or simply encourage exercise behavior, it is important to consider each individual’s unique set of characteristics at exercise initiation.Submission original under an indefinite embargo labeled 'Open Access'.

    Dispelling the Myths Behind First-author Citation Counts

    We 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

    We 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
