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
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
بررسی مشکلات و راهکارهای توسعه کیفی در نظام تحصیلات عالی
No full textThe primary objective of this research is to assess the challenges and propose solutions for enhancing the quality of higher education in Afghanistan. Employing a descriptive research method through document analysis, the study reveals that many universities in Afghanistan rely on conventional teaching methods and struggle to provide skilled professionals to society. It emphasizes the need for universities to nurture creative, entrepreneurial, and innovative individuals. Consequently, addressing the issue of rapid quantitative expansion in the higher education system is crucial, and efforts should be redirected towards ensuring quality development.هدف اساسی تحقیق، بررسی مشکلات و راهکارهای توسعه کیفی در نظام تحصیلات عالی کشور عزیز ما افغانستان است. روش تحقیق، توصیفی و به شیوه تحلیل اسنادی انجام شده است. عمدهترین یافتههای تحقیق عبارت است از: فعالیت اکثر پوهنتونهای افغانستان به اساس روشهای کهنه و سنتی استوار بوده و اکثراً پوهنتونها نمیتوانند بهقدر کافی افراد حرفهای و مسلکی را برای جامعه تقدیم کنند. پوهنتونها نباید مکانی باشد که تحصیلکردههای آن؛ غیرحرفهای و ناکارآمد باشد، بلکه باید حرفهای باشد که نیروی انسانی خلاق، کارآفرین و مبتکر را تربیت نماید. از اینرو، ضروری است که سرعت رشد کمی در نظام تحصیلات عالی و مؤسسات تحصیلی کشور متوقف شده و اقدامات اساسی در جهت عمقبخشی و توسعه کیفی در آنها صورت گیرد.هدف اساسی تحقیق، بررسی مشکلات و راهکارهای توسعه کیفی در نظام تحصیلات عالی کشور عزیز ما افغانستان است. روش تحقیق، توصیفی و به شیوه تحلیل اسنادی انجام شده است. عمدهترین یافتههای تحقیق عبارت است از: فعالیت اکثر پوهنتونهای افغانستان به اساس روشهای کهنه و سنتی استوار بوده و اکثراً پوهنتونها نمیتوانند بهقدر کافی افراد حرفهای و مسلکی را برای جامعه تقدیم کنند. پوهنتونها نباید مکانی باشد که تحصیلکردههای آن؛ غیرحرفهای و ناکارآمد باشد، بلکه باید حرفهای باشد که نیروی انسانی خلاق، کارآفرین و مبتکر را تربیت نماید. از اینرو، ضروری است که سرعت رشد کمی در نظام تحصیلات عالی و مؤسسات تحصیلی کشور متوقف شده و اقدامات اساسی در جهت عمقبخشی و توسعه کیفی در آنها صورت گیرد
Effect of planting distance and nitrogen fertilizer on the yield and physiological traits of Pinto bean (Phaseolus vulgaris L.)
Get PDFTo investigate the influence of planting distance and nitrogen fertilizer levels on yield and yield components of common bean (Phaseolus vulgaris L.) cultivars, a study was conducted in 2021 at the educational and research farm of the Daikundi Higher Education Institute. Employing a Randomized Complete Block Design (RCBD) Split-Plot arrangement with 2 replications, the research examined 4 planting distances (10, 15, 20 and 25 cm) as the primary factor and 3 nitrogen fertilizer levels (0, 50 and 100 kg N/ha) as the secondary factor. The analysis revealed that the highest seed yield for common beans, averaging 1220 kg/ha, was obtained with a planting distance of 25 cm and a nitrogen application rate of 100 kg N/ha. Conversely, the lowest yield, averaging 773 kg/ha, was recorded at the narrowest planting distance of 10 cm without nitrogen fertilization. Agronomic and physiological traits, such as increased total dry matter and leaf relative water content, were observed to positively correlate with grain yield in pinto beans. In contrast, reduced planting row spacing adversely affected seed yield, harvest index, phonological stages and other common bean characteristics, particularly at seeding stage. However, the application of 100 kg N/ha significantly improved certain measured traits. Based on these findings, the study recommends a combined agronomic practice of applying 100 kg N/ha and maintaining a planting row distance of 25 cm for optimal management of common bean crops in the Nili center of Daikundi province
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
