Hunting area affects chemical and physical characteristics and fatty acid composition of wild boar (Sus scrofa) meat
No full textWild boar populations have increased in the last few decades. The hunting will increase the availability of wild boar meat. the geographycal hunting area influenced the cooking loss percentage, dry matter and protein content. The major fatty acids in Longissimus thoracis muscle are oleic, linoleic, palmitic and stearic respectively
Buffalo meat quality, processing, and marketing: harnessing its benefits and nutraceutical potential
Get PDFBuffalo meat production is growing in different countries also because buffalo products exhibit some positive characteristics for human health compared to red meats from other species. However, meat quality is also defined by organoleptic aspects. This review aims to highlight the distinctive characteristics of buffalo meat. The principal problems of buffalo meat production are related to the low yield and an abundant layer of subcutaneous fat deposition when the animal is older than 14 months. This last trait, which may seem negative, allows us to carry out prolonged aging time (PAT) without compromising the shelf life and improving meat tenderness, one of the organoleptic characteristic’s consumers desires. Another organoleptic characteristic that guides consumer choice is color. This trait depends mainly on the amount and state of myoglobin, a species- specific sarcoplasmic heme protein, and buffalo presents a different molecule than beef. Furthermore, this bright red molecule in the oxidized state transforms into metmyoglobin or deoxy myoglobin in the absence of oxygen, giving a dark color to the meat, which consumers associate with poor quality from old animals. The presence or absence of oxygen shows advantages and disadvantages by acting on the one hand, on the bright meat color and, on the other, on the oxidation of lipids. The best compromise between the two situations is given by skin packaging, which preserves the meat in an anaerobic environment. Keeping the high nutritional quality over time is imperative to maintain the numerous nutritional properties of buffalo meat. In this regard, buffalo meat presents numerous distinctive characteristics among the different groups of fatty acids. Among the saturated one, the abundance of odd and branched fatty acids compared to the bovine breed should be highlighted; for the unsaturated ones, this meat is characterized by the abundance of biohydrogenation products by rumen bacteria such as trans vaccenic and conjugated linoleic acid (CLA), best known for its anti- carcinogenic properties. In comparison, the endogenous pathway of fatty acid formation through the liver or adipose tissue allows us to enhance the elongation capacity of polyunsaturated n3 fatty acids, vital for human health as precursors of anti-inflammatory prostaglandins. Finally, buffalo meat is an essential source of N- acetylneuraminic sialic acid (Neu5Ac), a nine-carbon molecule located in the terminal ends of glyco-proteins and glycolipids, an essential nutrient for brain development and function. This molecule can also counteract the intestinal absorption of N-glycolyl sialic acid (Neu5Gc) exogenous for humans, abundant in red meat, with high inflammatory action. In addition to being marketed as fresh meat, Buffalo meat can also be transformed into semi-processed or cured products with peculiar characteristics. Lean products could be well integrated into the modern diet, with clear advantages to consumers and breeders. The nutritional and technological potential of buffalo meat is considerable, and it is necessary to communicate this to the consumer, creating an efficient and dynamic market for buffalo meat-based products
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
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
