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

Home-based early intervention in infants at high risk for cerebral palsy: a protocol of a randomised controlled trial study with CareToy
Introduction
Care Toy (CT), a new technological system equipped with sensorized toys has been developed as a tele‐rehabilitation tool for home early intervention, recently tested in infants born preterm with promising results. This study aims to design a randomised controlled trial to evaluate the effectiveness of home‐based early intervention with Care Toy in infants at high‐risk for cerebral palsy (CP).
Patients and method
Infants born at term or preterm were recruited when showing: (1) specific or doubtful neurological signs at neurological examination and when using Prechtl's General Movement Assessment and (2) neuroimaging evidence of early brain lesion. After enrolment, the home‐based intervention will start when the infant reaches a minimum level of gross‐motor competences (i.e. initial head control). Recruited infants will be randomised in two groups: Care Toy intervention and infant massage. Infants allocated in the Care Toy group will receive the Care Toy system at home and will perform a highly customized goal‐directed intervention remotely monitored by rehabilitation staff. Infants allocated in the infant massage group will receive an infant massage parents’ course at home. Both early interventions will last 8 weeks. All enrolled infants will be evaluated with standardised scales and questionnaires at baseline (T0), at the end of the early intervention period (T1), 8 weeks after T1 (T2), and at 18 months of after term age (T3). Infant Motor Profile will be the primary outcome measure.
Results
The randomised controlled trial study started in September 2017, and enrolment is ongoing. The trial has been registered at www.clinicaltrials.gov (Identifier NCT03234959).
Conclusion
This work describes the randomised controlled trial methodology to evaluate the effectiveness of home‐based early interventions by Care Toy
