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
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
Physical activity behaviour of community-dwelling persons with traumatic spinal cord injuries in Cape Town, South Africa
No full textBackground: A spinal cord injury is a devastating condition, associated with permanent disability and decreased life expectancy. Persons with spinal cord injuries (PwSCIs) often lead sedentary lifestyles, which set in motion a cascade of comorbidities linked to lifestyle behaviours. There is growing evidence indicating that decreasing sedentary behaviour and improving physical activity (PA) are connected to favourable rehabilitation outcomes namely health status and physical functioning. There is paucity of evidence to support this postulation in our setting. Aim: The aim of this study was to assess PA behaviour of traumatic spinal cord injury (TSCI) patients in Cape Town/Western Cape. Methods: A quantitative cross sectional design was employed in this study. The population consisted of community- dwelling adults with traumatic spinal cord injuries (TSCIs). Only individuals who have lived in the community for at least one year following injury were recruited. Participants were sourced from the database (2016-2020) of Groote Schuur Hospital, Cape Town using a sample of convenience. A total of 403 adults with spinal cord injuries (SCIs) was retrieved from the database (2016-2020). From the 297 people who met the inclusion criteria, 76 participants were included in the study. A large proportion (n=214) could not be reached, 10 relocated to other areas and provinces in South Africa, and 2 declined to participate in the study
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
Survival and secondary medical conditions of persons with traumatic spinal cord injury in South Africa
Full text linkMagister Scientiae (Physiotherapy) - MSc(Physio)Background: A spinal cord injury (SCI) results in a change, either temporary or permanent,
in the cord’s normal motor, sensory or autonomic function. In addition, secondary medical
complications are common, following an SCI. As such, mortality risk in the spinal cord
community remains higher, when compared to the general population. Understanding the
complexity of factors related to mortality, remains paramount.
Aim: The overarching aim was to assess mortality and secondary medical complications, four
years after traumatic spinal cord injury (TSCI) in the City of Cape Town, South Africa.
Secondarily, factors associated with mortality and the development of secondary medical
complications were assessed.
Methods: A prospective, population-based design was used. The study population consisted
of all respondents with TSCI, who were enrolled in an earlier incidence study that was
conducted in 2013/2014. For this follow-up study, an inclusive sampling strategy was used.
All eligible respondents (N=145), or a family member of the deceased, were initially
telephonically contacted and requested to complete a valid and reliable interview-administered
questionnaire, to be completed face-to-face, or telephonically. Of those patients who were
deceased, a close family member, or former caretaker was asked to participate in this current
study. In order to aid the generalisability of the findings to the immediate source population,
every non-responder with information available from baseline data collected in 2013/2014,
were accounted for. Descriptive statistics were used to describe the cohort and to present the
mortality rate, as well as point-prevalence of secondary medical complications. Inferential
statistics, namely, bivariate logistic regression analysis, were used to identify factors associated
with mortality and the development of secondary medical complications
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
Health status and functioning after traumatic spinal cord injury in South Africa: Comparison between a private and a public health care funded cohort
No full textMagister Scientiae (Physiotherapy) - MSc(Physio)Introduction: A spinal cord injury is the damage to the spinal cord that alters functional
independence. Two different systems of care for the management of health conditions are
available in private and public care in South Africa. A better understanding of health and
functioning of individuals in the two systems is crucial to help address inequality between the
two systems. The aim of the study was to describe the health status and functioning of
persons with traumatic spinal cord injury (TSCI) in the Western Cape province who received
public-funded care compared with those in the Gauteng province who received private care.
Methodology: The study entailed a cross-section comparison between a government-funded
cohort in the Western Cape and a private cohort in Gauteng, two of the provinces of South
Africa. Self-administered questionnaires and standardised outcome measures were used to
collect the data and to ensure validity and reliability. Data were captured on Excel and then
transferred to SPSS (Statistical Package for Social Sciences) for analysis. Ethical clearance to
conduct the study was obtained from the Biomedical Research Ethics Committee of the
University of the Western Cape
