Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Obesity and Schizophrenia:Results of a Feasibility Study with Semaglutide to Assist Weight Loss
No full textINTRODUCTION: Weight gain has come to define the life experience of many individuals with schizophrenia and other severe enduring mental illnesses (SMI). In this clinical intervention study, we aimed to determine whether weekly treatment with the glucagon-like peptide-1 (GLP-1) agonist, semaglutide, as part of usual care, is feasible and acceptable to individuals in a psychiatric inpatient setting.METHODS: Fifteen inpatients (11 men/4 women) in a secure care environment, diagnosed with schizophrenia or schizoaffective disorder and with body mass index (BMI) of at least 30 kg/m 2 were commenced on weekly subcutaneous semaglutide as per standard of care. BMI and glycated haemoglobin (HbA1c) were measured at baseline and monthly follow-up to 6 months, and quality of life (QOL) was surveyed at baseline and 6 months. Analysis was based on intention-to-treat. RESULTS: Mean age of patients was 37 years (range 23-63). Time since diagnosis varied from 2 to 25 years. Mean initial BMI was 48.7 kg/m 2 for women and 37.2 kg/m 2 for men. Duration of semaglutide treatment ranged from 2-6 months. EuroQol 5-Dimensional Questionnaire, 5-Level Version Visual Analogue Scale (EQ5D5L QOL VAS) showed a mean improvement of + 7.5 (from 60 to 67.5) points. Improvement in QOL was overall significantly greater in those who remained on semaglutide (+ 9.5) than those who discontinued. Six patients discontinued semaglutide before the study end, including two who were discharged and no longer able to receive the intervention, and four who withdrew due to medical concerns. Individual percentage weight change varied from + 1 to - 12% (median 5%), and weight reduction was seen in all except two patients. All but one patient demonstrated a reduction in HbA1c levels. Mean HbA1c fell significantly from 41 (range 34-47) mmol/mol to 35.3 (31-45) mmol/mol. Importantly, all patients with baseline HbA1c in the non-diabetic hyperglycaemia range (42-47 mmol/mol) demonstrated a reduction of HbA1c to below 42 mmol/mol by 3 months. Prior to initiation of semaglutide, mean blood pressure was 127 (range 117-145) mmHg systolic and 82 (62-99) mmHg diastolic. At last assessment, average blood pressure was reduced to 121 (107-136) mmHg systolic and 79 (65-96) mmHg diastolic. CONCLUSION: In this feasibility study, weekly semaglutide treatment was associated with improvement in self-rated overall QOL and reductions in BMI, HbA1c and blood pressure at up to 6 months follow-up. Even in patients who discontinued treatment before 6 months, initial benefits of weight reduction and improved QOL were still demonstrated. Further evaluation, including health economic assessment and longer-term follow up, may support the expanded use of GLP-1 agonists in improving the cardiometabolic profile and longitudinal health outcomes in individuals with SMI.</p
Variations on the Author
Get PDF“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
Get PDFWe 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
Get PDFWe 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
