Steroid dependent asthma (SDA); Its variable presentation
No full textSDA (Steroid dependent asthma) is associated with a variable clinical and laboratory picture. Despite treatment with high dosages of oral and inhaled steroids patients remain symptomatic but generally stable. Airway obstruction and airway inflammation persist as reflected in sputum neutrophilia in most patients and significant (>2%) sputum eosinophilia in a majority of these patients
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
気管支肺胞洗浄液中リンパ球増多と患者年齢およびIgE系アレルギー反応との関連について
No full textThe proportion and number of lymphocytes in the airways were analyzed in 15 patients with a high proportion of lymphocytes in bronchoalveolar lavage (BAL) fluid (more than 30%) and in 17 patients with less than 20% of BAL lymphocytes. 1. Both atopic and nonatopic asthma patients with a high proportion of BAL lymphocytes were aged more than 50 years. In contrast, the age of patients with less than 20% of BAL lymphocytes ranged widely, from 29 to 63 years, in the two asthma types. 2. Age at onset of the disease, serum IgE levels, and ventilatory function test were not related to the proportion of BAL lymphocytes. 3. In patients with a high proportion of BAL lymphocytes, the mean proportion of these cells was 47.3% in atopic patients and 36.4% in non-atopic patients, i. e., there was no significant difference between the two asthma types. The absolute number of BAL lymphocytes in these patients was significantly higher in atopic (5.62×10(6)) than in nonatopic asthma (0.77×10(6)) (p<0.01). These findings show that an increased number of lymphocytes in the airways is clearly related to patient age and IgE-mediated allergic reaction.気管支肺胞洗浄(BAL)液中のリンパ球頻度が30%以上の15例および20%以下の17例の気管支喘息患者を対象に,BAL液中リンパ球頻度と年齢およびIgE系反応との関連について検討を加えた｡1.BALリンパ球が高頻度(30%以上)を示す症例は,アトピー型,非アトピー型を問わず,50才以上の年齢層に多い傾向が見られた｡一方,BALリンパ球20%以下の症例の年齢は,29-63才まで幅広く分布していた｡2.発症年齢,血清IgE値,換気機能とBAL液中リンパ球頻度との間には関連は見られなかった｡3.BAL液中リンパ球頻度が高い症例では,アトピー型では平均リンパ球頻度は47.3%,非アトピー型では36.4%であったが,両群間には有意の差は見られなかった｡しかし,BAL液中のリンパ球の絶対数は,アトピー型(5.62×10(6))において,非アトピー型(0.77×10(6)) に比べ有意に高い値を示した(p<0.01)。これらの結果は,気道内リンパ球の増加は,患者年齢とIgE系反応と密接に関連していることを示唆している
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
