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
Using 360° Video in Psychometric Assessment of Cognitive Functions: SemApp and its Usability data
No full textThe effectiveness of psychometric tests in assessing real-world abilities is increasingly emerging as an issue in the neuropsychological field. Researchers stress the importance of collecting information that is more comparable to what is observed in reality. In comparison to traditional paper-and-pencil tests, 360-degree technology appears as a promising tool for offering lifelike experiences in a controlled and safe manner, maintaining high levels of graphical realism and immersion. Moreover, it appears technical user-friendliness compared to traditional computer-based virtual reality. These characteristics seem to be essential components for resolving the validity problem. Thus, we aim to investigate the potential benefits of using 360-degree technology for memory assessment. Based on previous evidence, the present study aims to create a novel application focused on two crucial components of everyday memory: spatial and episodic memory. We present and test the usability of semApp, which is composed of an object recognition task and a spatial memory task. Both evaluate memory by simulating a real-life situation: a relocation and the exploration of a house. This cross-platform tool can be deployed on the patients’ devices (e.g., tablets and smartphones) and guarantee an objective and standardized evaluation. 7 end-users judged the usability of the application. They were Mild Cognitive Impaired patients, who evaluate semApp as a promising tool for enhancing the ecological value of standard memory assessment tests
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
Understanding the relationship between Traumatic experiences and Compulsive Internet use through the lens of mentalization: A mediation analysis
No full textThis study aimed to investigate the association between history of traumatic experiences, compulsive Internet use, and reflective functioning in an Italian sample. The relationship between history of traumatic experiences and excessive Internet use was fully mediated by uncertain reflective functioning. Contrary to literature, no gender influence was found. Our preliminary findings provide additional insight into the psychological processes underlying excessive Internet use
New Horizons for Neuropsychological Assessment: a Novel Platform for Building Cognitive Tasks with 360-degree Videos and Images
No full textNeuropsychological testing aims to evaluate cognitive abilities on a behavioral task. Most neuropsychological tests are conducted using paper-and-pencil modality or computerized protocols. Recent concerns about the effectiveness of these procedures have focused on their ecological validity, i.e., the relationship between test results seen in a laboratory setting and actual daily cognitive functioning. The emergence of virtual reality presents new clinical and experimental opportunities since it is focused on exposing people to simulated but realistic stimuli and environments while simultaneously maintaining a controlled laboratory environment and gathering cutting-edge measures of cognitive functioning. An additional opportunity for neuropsychological assessment in the field of VR are 360° immersive images and videos. Although recent studies have provided encouraging results for memory and executive function testing, their use in neuropsychological assessment is not yet so widespread. One issue might be the challenge of creating tools or modifying 360-degree videos in accordance with clinical requirements. This study aims to present a platform to develop ecologically valid and controlled environments, with standardized multimodal stimulation, precisely calibrated feedback about the performance, and automatic registration of outcomes. Two memory tests will be presented: an object recognition task and a spatial memory task. Implementing 360° media does not require the knowledge and understanding of advanced technical skills, and the equipment needed to record and visualize them is more affordable than a standard VR setup. By evaluating behaviors in real-world situations, this platform could make it possible to develop ecological testing or enhance existing ones with higher rate of ecological validity
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
