Effects of dietary high-oleic acid sunflower oil, copper and vitamin E levels on the fatty acid composition and the quality of dry cured Parma ham
No full textThe eects of seven isoenergetic dietary treatments: (1) no sunflower oil, 35 mg/kg Cu, without a-tocopheryl-acetate added; (2) to (7) 6% high oleic acid sunflower oil (HOSO), 35 or 175 mg/kg Cu crossed with a 0, 100 or 200 mg/kg a-tocopherol addition, were tested on quality characteristics of dry cured Parma hams from a total 84 Large White gilts. No statistically significant eect was detected on parameters of early evaluation of seasoning loss of hams. The seasoning loss and intramuscular fat content of seasoned hams averaged 28.1 and 3.3%, respectively, with no eect of the diet composition. The CIE L*a*b* colour values taken on the surface of the lean from Parma ham were not aected by dietary oil inclusion, nor by copper levels and by a-tocopherol addition in the feed mixture, except for the `a' value that increased in HOSO groups (P<0.01) and in groups with a-tocopherol addition (P<0.01). The TBARS values in lean were reduced by the inclusion of HOSO (P<0.05) and a-tocopherol supplementation (P<0.10). Compared to the no oil group, the Parma hams in the HOSO groups showed a higher oleic acid content in the covering fat, but not dierent in neutral and polar fractions from semimenbranosus muscle. The oil inclusion reduced the saturated fatty acid content in subcutaneous fat and neutral lipids fraction from muscle to 30±34% No eect of a-tocopherol and copper levels were observed on fatty acids profiles. From the subjects fed the HOSO diet softer Parma hams were produced than those fed the control diet (w2<0.05), while a-tocopherol and Cu levels did not influence the sensorial evaluation of hams. The inclusion of an oleic acid rich source in heavy pig diet brought about an improved nutritional value, but also the possible need of a prolonged ageing time to achieve an ideal firmness of Parma ham. Dietary a-tocopherol supplementation improved the red colour slightly and the lipid stability in Parma ham, while the supplementation of Cu in the diet had no influence on the tested parameters
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
Solitary kidney: the importance of a correct diet and adequate physical activity even in adolescence
No full textIntroduction: The probability of solitary kidney patients developing chronic kidney disease is higher than that of the general pediatric population. Modifiable risk factors such as diet, hydration, physical activity and obesity can influence the prognosis of these patients. The following study aims to quantify adherence to the Mediterranean diet and level of physical activity in solitary kidney children by surveying the parents of these children. In addition, parents were asked other questions about their child’s adherence to a low-sodium diet and physical activity, as well as any concerns they may have about their child’s physical activity. Finally, the prevalence of hypertension was evaluated. Methods: This cross-sectional study includes 47 patients (aged 3-17 years) of the pediatric nephrological ambulatory of Ospedale della Donna e del Bambino of Borgo Trento (Verona), carried out from October 2023 to January 2024. During the visit, we measure the blood pressure of the patient. The parents were subjected to completion of the questionnaires KIDMED: Mediterranean Diet Quality Index in children and adolescents and Godin-Shepard Leisure-Time Physical Activity Questionnaire, and we asked three questions to investigate the parents’ opinions about low sodium diet and physical activity. Conclusion: The nutritional and exercise-related aspects must complement the nephrological one in the follow-up of children affected by solitary kidney. KIDMED and Godin questionnaires can be incorporated into clinical practice to detect individuals at risk early, such as females and subjects with low scores on the KIDMED and GODIN questionnaires. The aim is to refine these patients’ nutritional and physical activity-related follow-up, decreasing the risk of short-and long-term consequences. The Adolescence represents an age historically known for poor compliance with appropriate dietary regimes and adequate levels of physical activity. It could represent a period of life in which the nutritional aspects of the follow-up of solitary kidney should not be underestimate
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
