Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
No full text“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
No full textWe 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
No full textWe 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
A quantitative comparison of manual vs. automated facial coding using real life observations of fathers
No full textThis work explores the application of an automated facial recognition software “FaceReader” [1] to videos of fathers (n = 36), taken using headcams worn by their infants during interactions in the home. We evaluate the use of FaceReader as an alternative method to manual coding – which is both time and labour intensive – and advance understanding of the usability of this software in naturalistic interactions. Using video data taken from the Avon Longitudinal Study of Parents and Children (ALSPAC), we first manually coded fathers’ facial expressions according to an existing coding scheme, and then processed the videos using FaceReader. We used contingency tables and multivariate logistic regression models to compare the manual and automated outputs. Our results indicated low levels of facial recognition by FaceReader in naturalistic interactions (approximately 25.17% compared to manual coding), and we discuss potential causes for this (e.g., problems with lighting, the headcams themselves, and speed of infant movement). However, our logistic regression models showed that when the face was found, FaceReader predicted manually coded expressions with a mean accuracy of M = 0.84 (range = 0.67–0.94), sensitivity of M = 0.64 (range = 0.27–0.97), and specificity of M = 0.81 (range = 0.51–0.97).</p
Perspectives on Contextual Information in Dutch Cardiac Rehab:Implications for Holistic Telemonitoring
No full textCardiac telerehabilitation (CTR) relies heavily on telemonitoring, predominantly gathering automated biophysical or survey data for clinical decision-making. However, lifestyle change during and after cardiac rehabilitation (CR) outside hospitals is impacted by many contextual factors, including mental well-being or social support. Failure to acknowledge these factors in remote cardiac care could result in healthcare professionals (HCPs) offering standardized recommendations that hinder health management. To gain insights into the utilization of contextual information in clinical decision-making in Dutch CR, we conducted semi-structured interviews with seven HCPs and CR experts. Our data analysis highlights the importance of routine, physical, and psychosocial information during holistic clinical decision-making. We argue for a transition towards a holistic approach to telemonitoring in CTR, discussing implications for more inclusive and contextual data-gathering practices
Patient Data Work with Consumer Self-tracking:Exploring Affective and Temporal Dimensions in Chronic Self-care
No full textEmerging studies are reporting on the implications of self-tracked data in patients’ everyday life and how it influences self-care activities in chronic care. The increased uptake of consumer wearable activity trackers in healthcare contexts and the wider application of advanced analytics is changing the temporal scope from ‘past-centric’ to ‘future-centric’ personal informatics. At the same time, a stream of research is making clear that experiences of emotion are constitutive of patient data work suggesting that the micro practices of engaging with personal data has an important affective dimension. We conducted an exploratory interview study with five chronic heart patients with an implanted cardiac device to conceptualize the data work, which is involved in making sense of self-tracked data from a consumer wearable activity tracker (Fitbit Alta HR). In this paper, we contribute to understanding patient data work as seven forms of micro practices: Verifying, Questioning, Motivating, Reacting, Accepting, Distancing, and Sharing. We discuss how these practices relate to temporal and affective dimensions of engaging with self-tracked data in chronic care and point to future research.</p
