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
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
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
The basic psychological needs in physical education scale in Filipino
No full textThe Basic Psychological Needs in Physical Education Scale (BPNPE Scale: Vlachopoulos, Katarzi, & Kontou, 2011) is a short instrument grounded in Self-Determination Theory (Ryan & Deci, 2000; 2002), designed to measure fulfillment of students’ basic needs for competence, autonomy, and relatedness in physical education context. The Greek version of this instrument has been reported to have adequate factor structure and strong internal reliability. Instruments developed in other culture need to be examined using a sample from the target culture in order to establish its cultural utility.
The primary aim of this study was to explore the factor structure, construct validity, and reliability of the Filipino BPNPE Scale. The secondary purpose was to test whether after-school sports participation is associated with students’ experience of needs fulfillment, autonomy support, and subjective vitality in physical education. The instrument was first translated to conversational Filipino via committee-approach back-translation procedure. Four hundred and eight (N = 408) Filipino high school students completed a two-page questionnaire assessing their needs fulfillment in physical education, as well as perceived teacher-autonomy support, and subjective vitality.
Principal axis factoring with direct oblimin rotation extracted a simple three-factor structure explaining 61.38% of the total variance. Individually, factor 1 accounted for 42.45% of the total variance, while the remaining two provided an additional 10.5% and 8.43%, respectively. These correlated factors (Range: .51 - .63) were consequently labeled as Relatedness need (4 items; α = .76), Competence need (4 items; α = .83), and Autonomy need fulfillment (2 items; α = .64). These three factors were significantly correlated with autonomy support and subjective vitality (Range: .37 - .47) supporting construct validity. However, test-retest reliability was weak and inadequate.
Additional analyses indicated that after-school sports participation had a significant effect on students’ experience of subjective vitality in physical education. More specifically, girls who participated in after-school sports experienced higher subjective vitality in physical education compared to their peers.
In summary, findings of this study provide preliminary support to the Filipino BPNPE Scale as a valid tool to assess basic psychological needs in physical education among Filipino high school students. Nevertheless, further scale revision and item refinement is necessary. The contribution of after-school sports participation to students’ experiences in PE is also highlighted.unknown accessibilityei tietoa saavutettavuudest

Brief remote intervention to manage food cravings and emotions during the COVID-19 pandemic: a pilot study

The published version can be accessed at the following link on the publisher’s website: https://www.frontiersin.org/articles/10.3389/fpsyg.2022.903096/fullAs a result of the COVID-19 pandemic people have endured potentially stressful challenges which have influenced behaviours such as eating. This pilot study examined the effectiveness of two brief interventions aimed to help individuals deal with food cravings and associated emotional experiences. Participants were 165 individuals residing in United Kingdom, Finland, Philippines, Spain, Italy, Brazil, North America, South Korea, and China. The study was implemented remotely, thus without any contact with researchers, and involved two groups. Group one participants were requested to use daily diaries for seven consecutive days to assess the frequency of experience of their food cravings, frequency of giving in to cravings, and difficulty resisting cravings, as well as emotional states associated with their cravings. In addition to completing daily food diaries, participants in group two were asked to engage in mindful eating practice and forming implementation intentions. Participants assessed their perceived changes in eating, wellbeing, and health at the beginning and end of the intervention. Repeated measures MANOVAs indicated that participants experienced significantly less food cravings (i.e., craving experience, acting on cravings, difficulty resisting), as well as lower intensities of unpleasant states associated with cravings across time (T1 vs. T7). In contrast to our hypothesis, the main effects of the group (food craving diary vs. food craving diary and mindful eating practice) were not significant. Participants reported less eating and enhanced wellbeing at the end of the study (T7 vs. T1). Our findings can be used to inform future remote interventions to manage food cravings and associated emotions and highlight the need for alternative solutions to increase participant engagement
