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
Studies on Heat-Resistant Non-Goagulating Substances of Serum Part 2. The estimation of heat-resistant non-coagulating substances in serum by means of polarography as applied to the cancer diagnosis
Full text linkWhile paying a due attention to the change in heat-coagulability of the serum of cancer patient, the author estimated the fluctuations of heat-resistant non-coagulating substance in the serum with polarography, and applying it on cancer diagnosis, studied the relationship between anemia, the leucocyte count, the rate of erythrocyte sedimentation, and the liver function
In addition, with the cases with gastric cancer the author studied the relationship between the fluctuations above mentioned and various supposed to exert in fluences on the height of the polarographic wave; and obtained the following results: 1. In the patients with gastritis, gastric and duodenal ulcers the polarography gives the negative cancer reaction in 100 per cent. 2. Gastric cancer patients show the positive cancer reaction in the polarograph in 92.9 per cent. 3. In the patients with malignant tumors other than gastric tumor the cancer reaction is positive in 79.2 per cent. Negative cases are found frequently in the cases with malignant tumors such as those of mammary glands and thyroid glands not belonging to the digestive system. 4. In various diseases other than malignant tumors (excepting gastric cancer) 73 per cent of them show negative cancer reaction, but positive raction can be frequently encountered in tuberculous disease, occlusion ileus, extensive disorders in the digestive system, and diseases of the reticulo-endothelial system. 5. No direct relationship can be recognized between the heat-resistant non-coagulation reaction of serum (Tsuda-Okujima's method) and the polarographic cancer reaction. 6. Neither any direct relationship can be observed between this cancer reaction and anemia, the leucocyte count, the plasma protein content, the rate of erythrocyte sedimentation, the liver functon, and jaundice. 7. As for the cases with gastric cancer: a. No relationship can be recognized between existence or non-existence of free hydrochloric acid in gastric juice and the height of polarographic wave. b. The greater the size of gastric cancer the higher is the height of the polarographic wave. c. There is no relationship between the site of gastric cancer and the height of polarographic wave. d. In the macroscopic classification (Borrmann) of tumors, it has been found that the height of polarographic weve increases along wirh the progress of the disease from type I to type IV. e. In those histologically suggesting undifferentiation and a higher degree of malignancy, the height of the polarographii wave is higher. f. Summarily viewing the course of progress in the symptoms of gastric cancer, as the disease progresses from the early stage to the terminal stage, the height of polarographic wave becomes higher
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
Studies on Heat-Resistant Non-Goagulating Substances of Serum Part 1. Changes in heat-resistant non-coagulating substances of the serum in the rabbits injected with extracts of human cancer tissue and gastric mucosa of benign disease and various factors involved
Full text linkIt is well known that the serum of cancer pationt possesses a specific coagulability to heat. By estimating heat-resistant non-coagulating substances of the serum in the rabbits previously injected with cancer tissue extract and benign gastric mucosa extract by Tsuda-Okujima's method the author pursued changes in these substances as well as inves tigated the relationship between the erythrocyte count, leucocyte count, and plasma protein content. The following are the results. 1. Rabbits given intravenous injection of cancer tissue extract to the ear-lobe show marked differences from those similatly injected with benign mucosa extract. 2. Observation for a long period of time is possible when extract is given intraperitoneal, and those injected with cancer tissue extract show a marked increase in heat-resistent non-coagulating substances when compared with those injected with benign mucosa extract. 3. There is a certain relationship between the change of the erythrocyte count and that of the hemoglobin content, namely, between the degree of anemia and the change of heatresistant non-coagulating substances in serum, but in the strict sense it is not a parallel relationship. 4. Between the leucocyte count and heat-resistant noncoagulating substance not any relatinoship can be recognized. 5. No completely parallel relationship can be recognized between the plasma protein content and heat-resistant noncoagulating substance. 6. Likewise no parallel relationship can be seen between tyrosine excreted in urine and heat-resistant non-coagulating substance
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
