Intermediate Wheatgrass (Thinopyrum intermedium) : a 360 ° evaluation
No full textIntermediate Wheatgrass (Thinopyrum intermedium), IWG, is a perennial grain currently being investigated for food uses. The benefits of perennial cultivation are manifold, including reduced nitrogen leaching and increased carbon sequestration. From a sustainability point of view, IWG seems like a perfect candidate for human food production, but for the food scientist, it does present certain challenges due to its composition. It does contain gliadins, and is thus not marketable as gluten-free, but it does not have the same profile or content of high-molecular weight glutenins and thus dough forming properties are poor compared to wheat. In addition, due to lower endosperm contents, the grain is lower in starch but higher in dietary fiber than more commonly cultivated grains. In recent years, researchers have investigated IWGs ability to form dough, its protein structures and interactions, as well as the effect of grain refinement on IWG dough rheology and bread-making performance. Starch gelatinization and retrogradation properties have also been investigated. Moreover, we are conducting storage studies evaluating rancidity due to autoxidation and enzymatic action, and phytochemical status. This presentation will provide an overview of the latest findings on IWG focusing on protein and starch features and their impact on final product quality. Improving the knowledge on IWG, its shelf life and its macromolecules will better define its application potential in human nutrition
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
Exploring the potential of perennial grain Intermediate Wheatgrass (Thinopyrum intermedium) as a novel food ingredient
No full textSustainable food production starts with sustainably produced ingredients. Cereals are staple foods all over the world, and all major cereals are annual plants. From an environmental perspective, the main advantage of perennials over annuals is the perennials’ extended root system. Introducing perennial alternatives to annual cereal crops would open up a new way for combating problems such as soil erosion and nitrogen leaching. Among the perennial grains currently explored for food cultivation is Intermediate Wheatgrass (Thinopyrum intermedium), IWG. However, cereals need to fulfill certain functional requirements, depending on the end use. Therefore, in collaboration with breeders, geneticists and agronomists, a team of food scientists is currently characterizing IWG breeding populations for parameters relevant to food use. Cereal proteins have the biggest influence on a grains’ application potential. The prolamin profile of IWG is similar to many other cereal grains: It is poor in high-molecular weight glutenins and therefore dough-forming ability, but does contain gliadins, and can therefore not be marketed as gluten free. Moreover, while breeders have succeeded in increasing endosperm to bran ratios, the grains are much thinner than more commonly cultivated grains. This leads to lower starch but higher dietary fiber contents. Our team has examined protein composition, structure and interactions during processing of whole and refined IWG, as well as blends thereof. We are currently conducting shelf life studies to determine optimum storage conditions of intact kernels. Grains are analyzed for parameters indicative of chemical and enzymatic rancidity, in addition to phytochemical status. Ultimately, our goal is to find optimum processing conditions to maximize IWGs success as a sustainably sound alternative to other grains
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
