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
Scientific basics to develop functional meat pâtés
Get PDFThe problems of providing consumers with healthy nutrition in sufficient quantities are typical for the entire modern world, and specialists are working hard to solve them, trying to harmonize the priorities of nutritional value with the basics of thrifty use of food resources. In this regard, it is important to develop functional food products, the composition and production technology of which rationally correspond to the nutritional needs of certain categories of consumers. The purpose of the article is to substantiate the use of the indicated vegetable raw materials in functional pâté products and to determine the quantitative parameters of their inclusion in formulations. To study the swelling and hydration of the samples, conventional laboratory methods were used, the water-retaining and fat-retaining capacities were determined by the Schoch method, the amino acid composition – by using the High-Performance Liquid Chromatography. The research has confirmed the feasibility of using plant flour and oils as sources of protein and fat to impart functional properties to meat products and to save valuable meat raw materials. Studies of the physical, chemical and functional-technological properties of flaxseed, rice, corn, sunflower flour showed that flaxseed and rice flour are the most suitable for creating formulations of functional meat products. The determination of the amino acid composition of these two types of flour showed a higher content of essential amino acids, including lysine, in flaxseed flour, which is very valuable for ensuring the proper functioning of the child's brain. For the rational conduct of research, a generalized scheme for planning formulations of functional pâté products was proposed, based on the properties of the used plant materials and the desired functional properties of these products. The practical value of the studies performed is that they made it possible to determine the necessary ratios of vegetable raw materials in the formulations of meat pâtés, which determine their functional propertie
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
Theoretical basics and technological characteristics of pork with typical syndromes
No full textIn the practice of meat processing, pork is often characterized by such syndromes as PSE (pale, soft, exudative), DFD (dark, firm, dry) and RSE (reddish-pink, soft, exudative). They worsen the perception of meats and have a negative impact on their technological properties in the production of meat products. In the total amount of pork used as raw material, meat with PSE and DFD syndromes features up to 50%. Studies have shown that PSE pork differed from quality meat (NOR) in a less elastic texture, the cut surface was soft, exudative, pale pink in color, and DFD pork was distinguished by a darker color. Compared to NOR meat, the pH value of pork DFD decreases during storage, while that of pork PSE increases. By appointing optimal feeding rations with the minimum necessary use of veterinary preparations, minimizing the causes of pig stress, choosing rational slaughter methods and regimens, it is possible to limit the impact of PSE syndrome and other common meat defects and im-prove pork quality

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
