Acupuncture and its use in chronic musculoskeletal pain
Musculoskeletal pain, and in particular osteoarthritis, continues to be a major problem for the population and the health service. The use of complementary and alternative medicine has become increasingly popular over the last 15 years; with acupuncture proving particularly popular in those with chronic musculoskeletal pain. Acupuncture has proved to be a very safe treatment option with serious side effects being very rare. The scientific basis for acupuncture is reviewed and various mechanisms are discussed including pain gate; diffuse noxious inhibitory control; bioelectricity; release of endogenous opioids and serotonin. The efficacy of acupuncture is still debated despite apparent large clinical effect size. One reason for this is that early trials were often of very poor quality. There is also the problem that there is no ‘industry standard’ placebo for acupuncture trials. However, more recent trials are much more rigorous and tend to show some efficacy for acupuncture, particularly in the short term. Acupuncture can not provide a ‘cure’ for degenerative disease such as osteoarthritis but may provide effective symptomatic relief from pain for certain musculoskeletal conditions

A background to acupuncture and its use in chronic painful musculoskeletal conditions
This article gives a brief description of the origins of acupuncture and describes some of the underlying philosophy behind this treatment and attempts to place it in context of the traditional Chinese medicine genre within which acupuncture is set. The article then explains the difference between traditional and Western style acupuncture and explains how point selection is made. The use of acupuncture is steadily increasing for a variety of reasons, it is a very safe intervention particularly when compared to conventional treatment and its lack of serious side effects might in part account for some of its popularity. The science behind acupuncture is also explored in terms of its underlying mechanisms and includes pain gate, endogenous opioids, diffuse noxious inhibitory control, serotonin and bioelectricity as possible explanations. The efficacy of acupuncture for a range of chronic musculoskeletal conditions is then explored and it is concluded that acupuncture has a place in the treatment of chronic musculoskeletal pain and in particular osteo-arthritis (OA). Where degenerative conditions are involved, acupuncture clearly cannot provide a ‘cure’ but can provide symptomatic relief, often over a prolonged period
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
We 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
