Get PDFIntroduction: Functioning is recognized as an important study outcome in chronic widespread pain (CWP). The Comprehensive ICF Core Set for CWP is an application of the International Classification of Functioning, Disability and Health (ICF) with the purpose of representing the typical spectrum of functioning of patients with CWP. The objective of the study was to add evidence to the validation of the Comprehensive ICF Core Set for CWP from the patient perspective. The specific aims were to explore the aspects of functioning and health important to patients with fibromyalgia, and to examine to what extent these aspects are represented by the current version of the Comprehensive ICF Core Set for CWP.Methods: The sampling of patients followed the maximum variation strategy. Sample size was determined by saturation. The focus groups were digitally recorded and transcribed verbatim. The meaning condensation procedure was used for qualitative data analysis. After qualitative data analysis, the identified concepts were linked to ICF categories.Results: Thirty-three patients participated in six focus groups. Fifty-four ICF categories out of 67 categories of the Comprehensive ICF Core Set for CWP were reported by the patients. Forty-eight additional categories that are not covered in the Comprehensive ICF Core Set for CWP were raised.Conclusions: Most ICF categories of the existing version of the Comprehensive ICF Core Set for CWP could be confirmed from the patient perspective. However, several categories not included in the Core Set emerged and should be considered for inclusion
Identification of essential elements of functioning in chronic widespread pain based on a statistical approach
No full textObjective. This study aimed to study the most relevant International Classification of Functioning, Disability, and Health (ICF) categories for describing functioning and disability in patients with chronic widespread pain (CWP). The specific aims of the study are (1) to identify which ICF categories explain the most variance of the experience of health in CWP and (2) to compare the identified ICF categories to the ICF categories of the Brief ICF Core Set for CWP.Design. The ICF categories entered in an initial regression model were selected according to their correlation with item 1 of the Medical Outcomes Survey 36-Item Short-Form Health Survey (SF-36). Based on an initial regression model, additional regression models were performed through systematically substituting the ICF categories included in the initial model with ICF categories from the same chapter with which they highly correlated.Results. Eleven categories were identified. Six of them are included in the Brief ICF Core Set for CWP.Conclusions. Most of the categories identified in the regression models are similar to the domains identified in Outcome Measures in Rheumatoid Arthritis Clinical Trials workshops and are represented in the Brief ICF Core Set for CWP, either directly or in ICF categories from the same chapters. Based on the 11 identified categories, clinicians and health professionals can obtain an efficient overview regarding the level of functioning of their patients in those essential areas that best differentiate among various levels of functioning
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
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
