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
Colorectal cancer : aspects of multidisciplinary treatment, metastatic disease and sexual function
No full textMore than 6000 people in Sweden are diagnosed with colorectal cancer annually. One out of five patients already has metastases at diagnosis. However, the occurrences of metastases at specific locations, e.g. peritoneal carcinomatosis and ovarian metastases, are not well known. The development of surgical and oncological treatment strategies for primary tumours and metastatic disease has led to a need to discuss colorectal cancer patients in a multidisciplinary team (MDT). Although oncologic cure and overall survival are the main goals of treatment, quality of life and functional results are becoming increasingly important with the prolonged survival. While male sexual dysfunction after rectal cancer treatment has been well described, considerably less data have been published about the impact on women. In addition to surgical trauma, female androgen insufficiency could be a contributing factor to sexual dysfunction. Radiotherapy for rectal cancer may increase the risk of reduced ovarian androgen production, but there is scant information on this in the literature.Papers I-III are large population-based cohort studies reporting on the effects of the development and implementation of MDT-conferences in patients with metastatic disease (Paper I) and the epidemiology of peritoneal carcinomatosis and ovarian metastases in colorectal cancer patients (Papers II–III). MDT assessment and metastasis surgery were more common in rectal cancer patients than in colon cancer patients, and the proportion increased over time. Peritoneal carcinomatosis was common, and risk factors were colon cancer, advanced tumour and nodal stage, fewer than 12 examined lymph nodes, emergency surgery, and a non-radical resection of the primary tumour. Ovarian metastases were uncommon, especially in rectal cancer patients. Paper IV assesses feasibility and internal and external validity in a prospective, observational cohort study on sexual function and androgen levels in women with rectal cancer. The methods were workable and the patients’ compliance was good. Comparison of clinical data from the study cohort with that of women who were eligible for inclusion but not included revealed a selection bias. Having a partner and sexual activity was more common among women who answered all questions in the questionnaires about sexual function compared with those who did not. A power calculation based on data from the first included patients showed that a larger sample size than initially planned for was needed.In conclusion, an increasing proportion of patients with metastatic colorectal cancer were discussed by the MDT. Predictors for and the occurrence of peritoneal carcinomatosis and ovarian metastases were defined, which may help to decide on individual treatment and follow-up regimens. The analysis of baseline data from the study on sexual function and androgen levels in women with rectal cancer indicates feasible methods but a selection bias. Inclusion of new patients in the study continues.List of scientific papersI. Differences in multidisciplinary team assessment and treatment between patients with stage IV colon and rectal cancer. J.

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
