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
Affect change with acute exercise: Determining an optimal dosage and testing thermogenesis and distraction as plausible mechanisms
Full text linkExercise is associated with an improved affect, whether this is causal has not been confirmed yet. Little research has been carried out to identify optimal duration or environment, but intensity studies tend to favour moderate for producing the best psychological benefits. This thesis comprises three studies. The main study had two aims, to determine an optimal dosage of exercise for affect changes, and to test two causal mechanisms, the thermogenic hypothesis and the distraction hypothesis of exercise and affect change. Study 1 was developed to determine which temperature site would be used to measure core temperature for the main study. Tympanic, oral and rectal measurement sites were tested, the rectal site provided clear results that were sensitive enough to detect core temperature changes with only a small variation between subjects. Study 2 looked at two mood questionnaires to determine sensitivity in registering small changes in affect. POMS-bipolar (Lorr and McNair, 1984) and PANAS (Watson et al, 1988) were selected for testing. The PANAS was chosen for the main study as it measured affect changes on a dimensional scale, took very little time to complete and was sensitive enough to pick up changes in affect with acute exercise. The main study used 9 exercise conditions made up of short (10 minutes), medium (20 minutes) and long (40 minutes) duration exercise and low (45 - 55% Hrmax), moderate (65 - 75% Hrmax) and high (80 - 89% Hrmax) intensity bouts; and 3 quiet rest conditions of similar short, medium and long duration. PANAS (Watson et al, 1988) and core temperature were measured before and after each condition. Moderate intensity exercise consistently produced most of the improvements in affect as research predicted. Intensity significantly influenced negative affect, but not positive affect. The medium and short duration exercise bouts produced more improvements in positive and negative affect than the long duration exercise. There was no evidence to support the thermogenic hypothesis, as core temperature changes did not correlate with affect changes. The quiet rest condition produced significant improvements for medium duration therefore supporting the distraction hypothesis. Future research could involve looking at delayed improved affect post exercise with particular interest in higher intensity exercise bouts. More research looking at how causal mechanisms may interact to produce an integrative model would be advised
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
Exploration of the COVID-19 mental health implications in elite disabled athletes
No full textThe COVID-19 pandemic influenced the way individuals conducted their lives, with consequences relating to mental health deterioration. Whilst researchers explored this outcome in the general population and athletic populations, less focus was on athletes with disabilities. The aim of this study was to investigate how the pandemic influenced the mental health of elite para-athletes in the United Kingdom. Nine elite-level athletes with disabilities participated in semi-structured interviews. Three broad themes were interpreted from the data using reflexive thematic analysis, two themes reflected the negative impact of COVID-19 on mental health and one theme reflected positive outcomes of the pandemic. Athletes explained that losing face-to-face interactions and delays in major sporting events were significant factors in their mental health decline. This population group reported different challenges to able-bodied communities. Differences included increased susceptibility to contract the virus, difficulties in communication where face masks and online interactions became necessary and perceptions of vulnerability relating to shielding protocols. Finally, positive outcomes related to the additional time to recover, to prepare for major events and time to reassess their values. Exploring experiences of a pandemic on this population group warrants further exploration to enhance the effectiveness of mental health support services in para-sporting organisations
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
Chapter 11: Destructive leadership in the context of sports
No full textRecently there has been significant expansion of knowledge relating to leadership in sporting contexts. Of particular interest has been the leadership provided by coaches, athlete leadership (peer leadership), and the development of both leadership and leaders. Often, the empirical and theoretical focus of this work has been to explore the positive impact of leadership provided by these sources. There is much less research that has investigated the destructive use of power and position within this context. As a result, this chapter seeks to better understand contemporary knowledge relating to destructive leadership in the context of sport. Concepts explored in this chapter include destructive leadership behaviours and the impact of the ‘dark triad’ of personality traits - narcissism, Machiavellianism, and psychopathy in sport. Consideration will be given to recognizing the role of followers within the coach-athlete relationship, and to potential environmental influences related to destructive leadership suggested to detrimentally influence sports outcomes
