    Going Beyond Counting First Authors in Author Co-citation Analysis

    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

    “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

    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

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    No full text
    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

    The art of blinking : a review of stimuli modality and attention on blink rates

    No full text
    This review aims to reconcile the contradicting results on mental workload and eye blink rate (EBR). While a series of studies such as those by Holland and Tarlow (1972, 1975) showed that higher mental workload is reflected by higher EBR, others such as Wood and Hassett (1983) and Fukuda, Stern, Brown, and Russo (2005) suggest otherwise. The emphasis of this review will be placed in the tasks employed in each study, which will be subsequently argued as the underlying factor for the conflicting results. Prior to the reviews, the basics on eye blinks will first be discussed to provide a physiological and neurological basis of argument. Subsequently, this paper will discuss the influence of stimuli modality and attention, referred to as nature of task in the paper, on the relationship between mental workload and EBR. In addition, this paper speculates the involvement of alpha power in playing a role in the interaction of stimuli modality and nature of task based on its involvement in similar neurological processes. Taken as a whole, the influence of alpha power is speculated to be the cause of EBR being context dependant. Specifically, higher mental workload will be reflected by lower EBR when visual stimuli is used. However, above a certain threshold, whereby mental workload is deemed too high, EBR will increase instead. Lastly, this paper concludes with the importance of understanding the relationship of EBR and mental workload by arguing its applicability in real-world scenarios, providing an applied function to the future research findings.Bachelor of Arts in Psycholog

    Smooth motion target displacements during eye blinks

    No full text
    This study investigates the relationship between the motion of a visual target and the perceived position of the target after eye blinks. Eye blinks disturb the visual feedback, and this will reduce the information received to process in the brain. This lapse of visual input is not noticed during spontaneous blinks. However, when blinks occur during the perceiving of a motion, it is unclear if participants would realise the errors when the continuity of the target’s motion is compromised. This study investigates the prediction of motion during the blink by analysing the perception of the participants when there is a target displacement in a target with a smooth motion trajectory. It considered whether the direction across a horizontal plane and velocity would affect the prediction of motion. Looking at the literature, it is hypothesised firstly that there would be an undershoot of the perception of motion when blinks occur. Secondly, this perception would be unaffected by horizontal directional difference. Lastly, there would be a difference in the perception of motion at different velocities during the blinks. A behavioural responses task was conducted using a smooth motion target stimulus. This study found that while there is no significant difference in the perception of the smooth motion stimulus when it travels in different directions, there is a significant difference in the perception of the smooth motion stimulus at different velocities. This has implications for the perception of time during blinks and opens up avenues to explore how the brain compensates for errors caused by blinks.Bachelor of Arts in Psycholog
