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
Late complications after total hip arthroplasty [Elektronisk resurs]
No full textThe present study concerns late complications after total hip arthroplasty in relation to implant material, design, and mode of implant fixation. Frictional characteristics in retrieved and new acetabular sockets was studied under dry and lubricated conditions comparing conventional polyethylene sockets with polyacetal sockets from the Christiansen prosthesis. No difference between new sockets of the two materials was found, whereas the friction in 12 retrieved polyacetal sockets was significantly higher than in 6 new and 6 retrieved polyethylene sockets. The annual average wear of 12 retrieved polyacetal cups was 240 + 50 mm[3]. Periprosthetic tissue samples from 18 patients with polyethylene and 16 with polyacetal sockets were assessed in a comparative morphological study showing significantly more inflammation and necrosis in the polyacetal group. Polyacetal wear particles were smaller (l-loµ) than those from polyethylene cups which may be an important factor for the severe tissue response. In a retrospective study 70 patients with uncemented Lord prostheses were followed for nearly 10 years. Pain and radiological changes were recorded at 1 and 5 years and at the latest follow-up. Twenty-five patients (36 %) complained of thigh pain. Radiological changes interpreted as adaptive bone remodelling, progressed throughout the period of observation. Physically active patients with thigh pain had less proximal bone loss than less active ones. New bone formation was associated with radiolucencies at the mid-stem level indicating that the elastic relative displacement may contribute to the pattern of bone remodelling seen with bulky uncemented implants. Thigh pain was not associated with any particular radiographic changes. In a series of retrieved modular Lord prostheses discoloration and dark deposits at the head-neck junction was found in 4 of 9 cases. Metallographic analysis of retrieved implants revealed material flaws close to the modular interfaces where severe corrosion had occurred. Bone and soft tissues at the implant site were similarly discoloured by corrosion products. Metal particles were often found in areas of extensive necrosis indicating a toxic reaction. Moreover, foreign-body granuloma and chronic inflammation were common findings, and in two cases we observed obliterative vascular changes similar to those previously described with metal-to-metal prostheses. Constituents of the alloys used in hip prostheses - notably chromium, nickel, and cobalt – are carcinogenic and there is concern over a possible association between total hip arthroplasty and cancer. Epidemiological data are scarce but two recent reports have indicated an increased incidence of lymphoma and leukaemia after hip replacement surgery. We studied the cancer incidence after hip arthroplasty in a cohort of 10,785 individuals operated in Stockholm County between 1974 and 1988, representing a total follow-up of 58,437 person-years at risk. The incidence of malignant tumors was not increased during the first decade after surgery
