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
الجاسوس علی القاموس (دراسۃ نقدیۃ تحلیلیۃ)
No full textLexical criticism is a crucial area of literary criticism, prominently represented by Al-Qamus Al-Muhit, which critiques Al-Jawhari's Al-Sihah. The author, Ahmad Faris Al-Shidyaq, emphasized lexical criticism throughout his dictionary, making it a significant reference in this field. The movement began in the early 10th century AH with scholars like Al-Suyuti and evolved in the 11th century with figures such as Baha' Al-Din Al-Amili. By the 14th century, it peaked under Al-Shidyaq and Ahmad Taymour, who both engaged critically with Al-Qamus Al-Muhit. Al-Shidyaq's work Al-Jasous 'ala Al-Qamus, features a preface and twenty-four critiques addressing phrases, structure, meanings, and word derivation in the dictionary. Although he memorized and utilized Al-Qamus Al-Muhit during his travels, he did not hesitate to critique it. His analyses reveal a mix of valid points and criticisms that may stem from textual corruption or his critical approach, highlighting the complexities of lexical criticism in Arabic literature
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
Prevalence and factors associated with dental caries among children aged 12 years in district Bannu-Pakistan
No full textDental caries or tooth decay is one of the most prevalent chronic infectious diseases in the world. In term of money it is a major public health problem for a significant proportion of the population. Apart from the teeth loss it is also a potential hazard for causation of cardiac and renal disease. Caries pattern is in transition; in developing countries its prevalence is increasing while in the developed countries it is constantly decreasing. In Pakistan an alarming number of people have this chronic problem. According to World Health Organization (WHO) report, in Pakistan 80 % people of age group 35-44 years are affected by dental caries. Among others one of WHO goal is that at 12 years of age the global average should not be more than 3 decayed, missing and filled teeth (DMFT). To achieve this goal WHO has chosen 12 years age group as the global monitoring age for caries. In Pakistan nowhere, a community-based study, of this age group has been reported. To assess prevalence and to identify factors associated with dental caries among 12 years old children we conducted a cross sectional study in District Bannu. We examined 623 [324 (52%) boys and 299(48%) girls] children and their DMFT score was recorded. Through pretested questionnaire, information about their age, gender, dietary habits, family income and knowledge attitude & practice of oral hygiene was taken. Drinking water fluoride level was measured by testing the water sample in a government laboratory at Islamabad. DMFT score was dichotomized and data analysis was done using Logistic Regression on SPSS-10 and SAS 6.12 software. Among \u27affected\u27, 144(53%) were girls and 127(47%) were boys and 569 (91%) of the affective were from rural and 54 (9%) were from urban area. Over all mean DMFT was 0.78 (0/3, 0.83) while for boys it was 0.70 (0.64, 0.76) and for girls it was 0.87(0.80, 0.93). Mean DMFT for rural area was 0.8 (0.75, 0.85) and for urban area it was 0.67 (0.59, 0.74). In multivariate analysis water fluoride level, family history, sweet intake, monthly income and cleansing method were found significant while adjusting for the other variables. Low income, water fluoride level \u3e 0.7 PPM and use of toothbrush showed protective effect. No significant difference was found between miswak and toothbrush. Recommendations: Drinking water supply should be tested for their fluoride concentration, if found below optimal level should be fluoridated. Miswak as an alternate method, for those who cannot afford toothbrush and toothpaste should be highlighted and propagated. More studies on different versions of miswak and its effective use are recommended
