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
Stop Procrastinating on Procrastination: An Exploration of Academic Procrastination Through the Lens of Self-Determination Theory
No full textA significant portion of students engage in the problematic behaviour of procrastination. Previous research has suggested that motivation, or a lack thereof, may play an important role in developing and maintaining this behaviour. From a self-determination theory (SDT) perspective, autonomous motivation results from having one’s basic psychological needs satisfied. Given this perspective, it is possible that targeting the basic psychological needs could have implications for procrastination. There have been few studies, however, that have examined the interaction between basic psychological need satisfaction, motivation, and procrastination from an SDT perspective. Furthermore, there have been no interventions for procrastination that have targeted these variables. Broadly, the goal of the present research is to examine the relationships between basic psychological needs, academic motivation, and academic procrastination, and to develop and implement an intervention targeting academic procrastination based on SDT as a theoretical framework. Given that previous research has suggested the utility of motivational interviewing (MI) in the context of SDT, this study will use MI techniques to target SDT variables. The first study examined the role of each of the basic psychological needs (BPN) and their relationship with the different types of academic motivation (autonomous, controlled, and amotivation) and academic procrastination through a mediation model where academic motivation mediates the relationship between BPN satisfaction and frustration, and academic procrastination. A sample of undergraduate students (N= 617) completed an online questionnaire about their university experience. The data was analyzed using a mediational structural equation model. Results suggested that the different types of academic motivation partially mediated the relationship between BPN satisfaction and procrastination, but not the relationship between BPN frustration and procrastination. The second study used the first study as a theoretical foundation for the design and implementation of a brief intervention that used SDT as a theoretical framework and MI strategies to target the three BPN as a means of increasing autonomous motivation and decreasing academic procrastination. Two hundred and twenty-three university students were randomized to the intervention or control groups. The participants completed an online questionnaire pre- and post-intervention. Results suggested that our intervention increased BPN; however, it did not significantly increase autonomous motivation or decrease academic procrastination. The findings of the second study demonstrated the effectiveness of MI strategies in targeting BPN. As a whole, the current research contributed to a more nuanced understanding of the relationships between BPN satisfaction and frustration, the different types of academic motivation, and academic procrastination. It also highlights the effectiveness of MI strategies in targeting BPN variables, as well as future theoretical and methodological considerations when designing future procrastination interventions
Academic Procrastination in Undergraduate Students: Understanding the Role of Basic Psychological Need Satisfaction and Frustration and Academic Motivation
Full text linkProcrastination is particularly prevalent in the post-secondary student population, with prevalence rates ranging between 70–95%. Students have consistently cited motivation, or a lack thereof, as one of the main sources of their procrastination. One of the most prominent theories explaining motivation is self-determination theory (SDT). Despite the direct links between motivation and procrastination, procrastination has been scarcely examined through the lens of SDT. The current study examined the relationship between basic psychological need (BPN), satisfaction and frustration, academic motivation, and academic procrastination. A sample of 617 undergraduate students completed an online questionnaire about their university experience. Data were analyzed using mediational structural equation models. Results suggested that academic motivation significantly mediated the relationship between BPN satisfaction and procrastination, but not the relationship between BPN frustration and procrastination. These results demonstrate the importance of satisfying the BPN of undergraduate students, as it may increase their academic motivation and, subsequently, reduce their procrastination.La procrastination est particulièrement répandue dans la population étudiante postsecondaire, avec des taux de prévalence allant de 70 à 95 %. Les étudiants citent systématiquement la motivation, ou le manque de motivation, comme l’une des principales sources de leur procrastination. L’une des théories les plus importantes expliquant la motivation est la théorie de l’autodétermination (TAD). Malgré les liens directs entre la motivation et la procrastination, cette dernière a rarement été examinée sous l’angle de la TAD. La présente étude examine la relation entre la satisfaction et l’insatisfaction des besoins psychologiques fondamentaux (BPF), et la motivation et la procrastination scolaires. Un échantillon de 617 étudiants de premier cycle a rempli un questionnaire en ligne portant sur leur expérience universitaire. Une analyse de médiation des données a été réalisée à l’aide de modèles d’équations structurelles. Les résultats indiquent que la motivation scolaire a un effet médiateur significatif sur la relation entre la satisfaction des BPF et la procrastination, mais pas sur la relation entre l’insatisfaction des BPF et la procrastination. Ces résultats démontrent l’importance de satisfaire les BPF des étudiants de premier cycle, car cela peut augmenter leur motivation scolaire et, par conséquent, réduire leur procrastination
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
