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
The role of dermoscopy and digital dermoscopy analysis in the diagnosis of pigmented skin lesions
No full textIN THE PAST FEW DECADES, THE INCIDENCE RATE OF cutaneous melanoma has increased more rapidly than for any other cancer.1,2 This has been attributed partly to a real change in the incidence rate of the disease and partly to greater surveillance. 3,4 Unfortunately, advanced melanoma is still practically incurable, and a favorable prognosis depends on specific prevention and early detection. Recognition in the initial stage is currently the best factor for complete recovery.5 Diagnostic accuracy has improved since noninvasive methods such as classic or digital epiluminescence dermoscopy and digital dermoscopy analysis (DDA) became available to dermatologists.6-10 These methods permit enlargement and evaluation of lesion images from the surface down to the depth of the dermoepidermal junction.
Many studies7,11 have shown a significantly improved accuracy in diagnosing melanoma when these instruments are used by expert clinicians. However, many dermatologists are still diffident about using instruments or machines to diagnose melanoma
Segmental phenolization for the treatment of ingrowing toenails: a review of 6 years experience
No full textBACKGROUND: Ingrowing toenails are a common problem causing significant morbidity. Many of the procedures used for treating this painful condition cause considerable discomfort and have high failure rates. In recent years, phenol cauterization of the nail bed has been used increasingly. METHODS: A retrospective study was carried out of all patients treated by this method in the authors' clinic during the period January 1996 to December 2001. In this study, phenol cauterization is the standard form of treatment and 948 phenol cauterizations were carried out in 764 patients. RESULTS: There was no significant morbidity and the procedure was tolerated well by all patients. Overall recurrence was 4.3% (33 patients) after 18 months. All symptomatic recurrences were successfully treated by repeating phenol cauterization. CONCLUSIONS: Phenol cauterization compares favourably with other surgical ablation techniques for ingrowing toenails and may be the ablation procedure of choice of an ingrowing toenail
