Third prize: chiropractic and the national health care system: a basis for partnership in the UK
No full textBackground: Changes in United Kingdom (UK) health care policy and legislation have the potential to radically change care for patients with musculoskeletal conditions by widening access to manipulation services under its National Health Service (NHS).Objective: To investigate chiropractors’ past and current provision of musculoskeletal services for NHS patients and optimal future arrangements.Methods: One thousand forty-two UK chiropractors on professional registers were sent a 2-part questionnaire. The profession was divided into 2 groups and each group answered part of the questionnaire from either a practitioner or patient perspective.Results: Sixty-nine percent responded. Of these, 29% had previously provided services for NHS patients, and 18% were currently providing them, reporting moderate to high levels of satisfaction. Ninety-five percent were interested in future arrangements but on a part-time basis and in a way that most closely resembled private practice.Conclusion: The majority of UK chiropractors favor future partnership with the NHS. National health care reform and the statutory self-regulation of chiropractors have brought this closer to a more widespread reality. However, to prosper in this setting, the profession may benefit from a greater understanding of the competing priorities and constraints faced by NHS purchasers, who, for their part, should be prepared to implement policy based on evidence
Midlumbar lateral flexion stability measured in healthy volunteers by in vivo fluoroscopy
No full textStudy Design: prospective fluoroscopic and electromyographic study of coronal plane lumbar spine motion in healthy male volunteers.Objectives: assess the intervertebral motion profiles in healthy volunteers for symmetry, regularity, and neutral zone laxity during passive recumbent lateral bending motion.Summary of background data: previous continuous in vivo motion studies of the lumbar spine have mainly been limited to active, weight-bearing, flexion-extension (sagittal plane) motion. No data are available for passive lateral bending or to indicate the motion profiles when muscle activity is minimized.Methods: thirty asymptomatic male volunteers underwent video-fluoroscopy of their lumbar spines during passive, recumbent lumbar lateral bending through 80° using a motor-driven motion table. Approximately 120 consecutive images of segments L2–L5 were captured, and the position of each vertebra was tracked throughout the sequence using automated frame-to-frame registration. Reference intervals for intervertebral motion parameters were calculated. Surface electromyography recordings of erector spinae were obtained in a similar group of volunteers using the same protocol without fluoroscopy to determine to what extent the motion was completely passive.Results: correlations between intervertebral and lumbar motion were always positive in controls and asymmetry was less than 55% of intervertebral range. The upper reference interval for the slope of intervertebral rotation in the first 10° of trunk motion did not exceed 0.46 for any level. Muscle electrical activity during the motionwas very low. Examples from patient studies showed markedly different results.Conclusion: these results suggest that reference limits from asymptomatic data for coronal plane passive recumbent intervertebral motion may be a useful resource forinvestigating the relationship between symptoms of chronic (nonspecific) low back pain and biomechanics and in the clinical assessment of patients and interventionsthat target the passive holding elements of the spine. Data pooling from multiple studies would be necessary to establish a complete database<br/
The effectiveness of a posted information package on the beliefs and behavior of musculoskeletal practitioners the UK chiropractors, osteopaths, and musculoskeletal hysiotherapists Low Back Pain Management (COMPLeMENT) randomized trial
No full textStudy Design. Randomized controlled trial.
Objective. To investigate the effect of a printed information package on the low back pain (LBP)-related beliefs and reported behavior of musculoskeletal practitioners (chiropractors, osteopaths, and musculoskeletal physiotherapists) across the United Kingdom.
Summary of Background Data. A substantial proportion of musculoskeletal practitioners in United Kingdom does not follow current LBP guideline recommendations.
Methods. In total, 1758 practitioners were randomly allocated to either of the 2 study arms. One arm was posted a printed information package containing guideline recommendations for the management of LBP (n = 876) and the other received no intervention (n = 882). The primary outcome measure consisted of 3 "quality indicators" ( activity, work, and bed-rest) relating to a vignette of a patient with LBP, in which responses were dichotomized into either "guideline-inconsistent" or "guideline-consistent." The secondary outcome was the practitioners' LBP-related beliefs, measured using the Health Care Providers Pain and Impairment Relationship Scale. Outcomes were measured at baseline and at 6 months.
Results. Follow-up at 6 months was 89%. The changes in reported behavior on the quality indicators were as follows: activity, odds ratio (OR) 1.29 (95% confidence interval, 1.03-1.61) and number needed to be treated (NNT), 19 (15-28); work, OR 1.35 (1.07-1.70) and NNT 19 (14-29); and bed-rest, OR 1.31 (0.97-1.76) and NNT 47 (33-103). The composite NNT for a change from guideline-inconsistent to guideline-consistent behavior on at least 1 of the 3 quality indicators was 10 (9-14). LBP-related beliefs were significantly improved in those who were sent the information package (P = 0.002), but only to a small degree (mean difference, 0.884 scale points; 95% confidence interval, 0.319-1.448).
Conclusion. Printed educational material can shift LBP-related beliefs and reported behaviors of musculoskeletal practitioners, toward practice that is more in line with guideline recommendations
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
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
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
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
