Effects of Modified Atmosphere Packaging and Chitosan Treatment on Quality and Sensorial Parameters of Minimally Processed cv. ‘Italia’ Table Grapes
Full text linkTable grape is a non‐climacteric fruit, very sensitive to water loss and gray mold during
postharvest handling and storage. The aim of this work was to evaluate the effects of modified atmosphere
packaging and chitosan treatment on quality and sensorial parameters of minimally processed
cv. ‘Italia’ table grape during cold storage (14 days at 5 °C) and shelf‐life (7 and 14 days of
cold storage plus 5 days at 20 °C), reproducing a retail sales condition. Our data showed a significant
effect of high CO2‐modified atmosphere in combination with chitosan and alone on preserving quality,
sensorial parameters, and delaying decay of minimally processed table grape. The most effective
treatment in terms of preservation of quality, sensory, and nutritional quality was high‐CO2 modified
atmosphere packaging plus chitosan treatment. The overall results showed that when a proper
modified atmosphere packaging is combined with a postharvest chitosan treatment, gray mold
growth can effectively be controlled in ready‐to‐eat cv. ‘Italia’ table grape and that modified atmosphere
packaging (MAP) with high levels of CO2 and reduced concentration of O2 in combination
with chitosan treatment could prevent the negative effect of high‐CO2 in‐packages level, like berry
browning and rachis browning and dehydration
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
Postharvest application of sulphur dioxide fumigation to improve quality and storage ability of "red globe" grape cultivar during long cold storage
No full textTable grape cv 'Red Globe' is produced in Sicily and in other areas of Southern Italy. This produce is very appreciated by consumers, having the best rankings in the world market for exports and quality. Nevertheless, despite it is a non-climacteric fruit, table grape is very perishable, both after harvest, and during postharvest handling and cold storage. In fact, also at low temperatures, table grape is very sensitive to fungal infection (Botrytis cinerea) and other diseases, like gray mold, which is very aggressive. For this reason, a standard practice is to fumigate table grape with sulphur dioxide (SO2), after storage in chambers. The growing market request of table grape cv. 'Red Globe' enhanced postharvest research on better techniques aimed to maintain the grapes for longer periods, in order to satisfy the demand. Therefore, the object of this study is to assess the effect of cold storage, at 1±0.5 °C and 93±2% relative humidity (RH), of table grape cv 'Red Globe', for 4 months, with low concentrations of SO2 (0.20%), with the aim to extend their post-harvest shelf life. Two samples of Red Globe table grape were stored at 1±0.5°C, the first for control without SO2, and the other treated with low concentration of SO2. Both samples were moved every 15 days, to 20 °C for 3 days, for simulating shelf life and berry decay. Results showed that, 'Red Globe' table grape treated with low concentration of SO2, prolonged its shelf life for three months after harvest. More particularly, firmness, weight loss, total soluble solids content and titratable acidity maintained good values, and rachis and berry decay were inhibited. This technique is a good alternative to the SO2 one or dual release generating pads for maintaining grape quality in extended storage, with lower impacts for the environment and lower costs
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
