Perceived diagnostic uncertainty in pediatric chronic pain
Get PDFIn this review, we argue that perceived diagnostic uncertainty in idiopathic pediatric chronic pain patients and their parents is critically important for understanding pain cognitions, behavioral responses to pain, treatment choices, and outcomes during this developmental period. We include evidence from children (under 12 years) and adolescents (12-18 years). This period sets the stage for future experience of pain: two thirds of children and adolescents with chronic pain will become adults with chronic pain [30]. The prevalence of pediatric chronic pain is rising, and has been described as a growing epidemic [11]. Better understanding of this core issue through well-designed research with pediatric populations is therefore crucial
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
‘Drawing a line in the sand’: Physician diagnostic uncertainty in paediatric chronic pain
Get PDFBackground: Diagnostic uncertainty is the subjective perception of an inability to provide an accurate explanation of the patient’s health problem or that a label is missing or incorrect. While recently explored in youth with chronic pain and families, this is the first study to investigate diagnostic uncertainty from the perspectives of physicians. Methods: Individual, semi-structured interviews were conducted with sixteen pediatricians who assess and/or treat youth who experience complex chronic pain. Interviews explored pediatricians’ perceptions, beliefs, and confidence regarding the assessment and management of chronic pain in youth and how they manage uncertainty regarding the diagnosis. Interviews were analysed using inductive reflexive thematic analysis. Results: Analyses generated one prominent theme: ‘drawing a line in the sand’. Within this theme, physicians discussed uncertainty as inherent to their role treating youth with chronic pain. The metaphor of ‘drawing a line in the sand’ was used to describe a process of identifying a point at which physicians no longer sought a new diagnosis for the child’s pain or continued diagnostic investigations. This line was influenced by numerous factors, which are highlighted through four subthemes: physician training, experience, and mentorship; individual patient and family factors; perceived reassurance of diagnostic investigations; and the broader social context and implications. Conclusions: How physicians manage diagnostic uncertainty must be understood, as it is likely to critically impact how a diagnosis of chronic pain is communicated, the diagnostic investigations undertaken, the wait time to receiving a diagnosis, and ultimately youths’ pain experiences. <br/
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
Diagnostic uncertainty in pediatric chronic pain: Nature, prevalence, and consequences
Get PDFIntroduction: Diagnostic uncertainty (DU), which is the perception that a label or explanation for a patient’s health problem is missing or inaccurate, has been linked to distress, anxiety, and difficulty coping among adults with pain. This study examined the prevalence of DU among youth with chronic pain and their parents and the relation of parent and youth DU with youth pain, pain-related constructs, and health-related quality of life.Methods: Participants included 174 youth with chronic pain (Mage=14.28 years; 73% female) and one of their parents (91% mothers) recruited from a tertiary-level pediatric chronic pain program in Canada. Youth and parent DU was assessed using a brief measure of three empirically-derived yes/no questions regarding whether the youth and parent had received a clear diagnosis/explanation for their/their child’s pain and whether they believed there was something else happening with their/their child’s pain which doctors had not yet found. Youth reported on their pain intensity, pain interference, pain catastrophizing, fear of pain, and health-related quality of life. Results: 31% of youth and 28% of parents experienced DU. 70% of parents and youth were in agreement regarding their experience of DU. Youth DU was linked to higher youth catastrophic thinking about their pain. Parent DU was linked to greater youth pain interference and intensity and lower youth health-related quality of life. Discussion: DU is experienced by nearly a third of youth with chronic pain and their parents and is linked to worse youth pain, pain catastrophizing, and health-related quality of life. <br/
