Do-it-yourself approach applied to the valorisation of a wheat milling industry's by-product for producing bio-based material
No full textCereal processing and flour production play a key role in the Italian agrifood scenario generating valuable economic incomes and contributing significantly to the export market. The European Union's commitment to the transition towards the Circular Economic model has led to increasing attention to food by-products and waste valorisation practices in order to reduce the amount of food loss and waste and costs for disposal. Processing outputs produce secondary raw materials which often remain unexplored for alternative applications and other supply chains. This article focuses on the use organic residues obtained by cereal processing conducted by a small-size milling industry to produce bio-based materials. The research is structured in two stages: (1) the first investigates the production of organic waste through material flow analysis and characterisation of wheat dust, which is considered as waste, through nutritional and toxicological analyses; (2) the second explores the opportunity of using wheat dust as reinforcing filler for a starch-based bio-composite and as culture medium for a microbial cellulose. This second stage adopts the do-it-yourself (DIY) approach for upcycling of food waste and manipulation of bio-based materials. The wheat dust/starch bio-composite was processed to obtain surrogates of disposable plates, while the microbial cellulose was manipulated to achieve a film for food packaging. Strengths and criticalities of both applications are discussed, considering limitations implied by the DIY approach, and further implementations are defined. This article focuses on a case study located in Cuneo province (Piedmont Region, Italy), but it also considers the opportunity to upscale the study to larger milling industries due to the relevance of wheat grains processing in the Italian agrifood market
Progetto Glume: from milling waste to resource for new materials
Full text linkThe paper discusses the results of experimental research concerning the enhancement of waste from wheat milling. It focuses on the analysis of Mulino Marino's production system, a leader cereals' milling company in the Cuneo province. The analysis of material flows identifies wheat husks and organic sand (about 30% of total wheat grains) as processing residues not classified as by-products that must be discarded as waste, following current regulations. Chemical-physical characterization certifies that they present qualities that are not optimized in their current end-of-life management. Looking at the main purposes of the circular bio-economy and the SDG12, the study focuses on defining a craft protocol for testing potential uses of company's organic waste through a set of basic experimental tests to investigate performances of wheat husks as a biopolymer, similar to thermoplastics, and as a compound for a bio-based material to replace to disposable plastics (e.g. for packaging)
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
Full text linkWe 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
