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
Agroindustry by-product – green leaves: A new source of protein and bioactive compounds
Get PDFU okviru ove doktorske disertacije istraživanja su bazirana na ekstrakciji proteina iz nusproizvoda prerade povrća – zelenog lišća, sa ciljem ispitivanja njihovih funkcionalnih i bioloških karakteristika, kao i razvoja novih formulacija prehrambenih proizvoda na bazi ovih proteina. Akcenat je stavljen na valorizaciju nusproizvoda agroindustije koji nastaju nakon uzgoja i branja povrća u cilju dobijanja novih proteina. Istraživanja su sprovedena na proteinima dobijenih iz lišća karfiola, brokolija, kupusa i cvekle. U prvoj fazi istraživanja, dobijeni proteini lišća primenom alkalne ekstrakcije iskarakterisani su u pogledu funkcionalnih i bioloških osobina, ispitana je njihova svarljivost kao i antioksidativni potencijal dobijenih hidrolizata. U drugoj fazi, istraživanja su bazirana na unapređenju procesa ekstrakcije proteina lišća primenom ultrazvučnog i enzimskog predtretmana, a efikasnost ekstrakcije praćena je ispitivanjem funkcionalnih i fizickih karakteristika dobijenih proteina lišća. U trećoj fazi, istraživanja su sprovedena sa fokusom na ugradnju proteina lišća brokolija kao funkcionalnog dodatka u prehrambeni matriks sa ciljem dobijanja novog proizvoda, i ispitivanja njegovih fizičko – hemijskih, strukturnih i senzornih osobina, in vitro digestije i antioksidativnog potencijala nakon varenja. Rezultati prikazani u ovoj doktorskoj disertaciji čine naučno saznanje o primeni tehnika za ekstrakciju proteina iz zelenog lišća, a takođe i o dobijanju prehrambenih proizvoda unapređenih bioloških i nutritivnih osobina koji mogu odgovoriti na sve veće zahteve i potrebe potrošača za funkcionalnom hranom.The research of this doctoral dissertation, was based on the extraction of proteins from the by-products of vegetable processing - green leaves, with the aim of examining their functional and biological characteristics, as well as the development of new formulations of food products based on these proteins. Emphasis is placed on the valorization of by-products of the agroindustry that are created after growing and picking vegetables in order to obtain new proteins. Research was conducted on proteins obtained from the leaves of cauliflower, broccoli, cabbage and beets. In the first phase of the research, leaf proteins obtained using alkaline extraction were characterized in terms of functional and biological properties, their digestibility was examined, as well as the antioxidant potential of the obtained hydrolysates. In the second phase, research is based on the improvement of the leaf protein extraction process using ultrasonic and enzymatic pretreatment, and the efficiency of the extraction is monitored by examining the functional and physical characteristics of the obtained leaf proteins. In the third phase, research was conducted with a focus on the incorporation of broccoli leaf protein as a functional additive in the food matrix with the aim of obtaining a new product, and testing its physical-chemical, structural and sensory properties, in vitro digestion and antioxidant potential after digestion. The results presented in this doctoral dissertation constitute scientific knowledge about the application of techniques for extracting protein from green leaves, and also about obtaining food products with improved biological and nutritional properties that can respond to the increasing demands and needs of consumers for functional food

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
