BMMIB : Behind Microbe : Microbe Interactions in Blue cheeses
Full text linkGorgonzola is a blue-veined, mould-ripened cheese, made from pasteurized cow’s milk inoculated with starter cultures (Streptococcus thermophilus and Lactobacillus delbrueckii), along with Saccharomyces cerevisiae and Penicillium roqueforti, the main responsible for the aroma and flavor of the cheese at the end of ripening. The microbial interactions that occur during the ripening process are crucial for the correct development of the final product, which is severely controlled to fulfill the standards of its PDO denomination. These interactions have been studied poorly in the past years: for this reason the aims of this work are i) the characterization of the evolution of microbial populations in each phase of ripening, using traditional microbiological approaches, together with a metagenetics analysis, ii) the enzymatic quantification of microbial metabolites pathways involved during cheese ripening, together with mass-spectrometry analysis and iii) the development of a species-specific primer set for the quantification of Penicillium roqueforti mycelium by qPCR during cheese ripening
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
BMMIB-BEHIND MICROBE-MICROBE INTRACTIONS IN BLUE CHEESE
Full text linkGorgonzola is a blue-veined, mould-ripened cheese, made from pasteurized cow’s milk inoculated with starter cultures (Streptococcus thermophilus and Lactobacillus delbrueckii), along with Saccharomyces cerevisiae and Penicillium roqueforti, the main responsible of the aroma and flavour of the cheese at the end of ripening. For this reason, monitoring the fungal growth and unravel the microbial dynamics during the ripening process is crucial. Traditional methods based on colony forming unit (CFU) along with alternatives (ergosterol, dry weight, spores counting) are not suitable for hyphal filaments quantification in the cheese matrix. Here we monitored and compared the P. roqueforti development between two Gorgonzola productions from two different years and the same plant, by means of a qPCR assay, mass spectrometry-based chemical analysis and an assay with a glutamate-sensitive luminescent biosensor for the evaluation of proteolysis. qPCR assay was based on a species-specific primer set targeted on ari1 gene. This assay allowed the monitoring of P. roqueforti development during cheese ripening. The lipolysis and proteolysis cheese profiles obtained by mass-spectrometry and luminometric analysis were in good agreement with the qPCR data, revealing that the most relevant blooming of the mould occurs after 20 days of ripening, and that the most recent production had a lower amount of fungal mycelium produced and a lower enzymatic activity, thus affecting the final product quality. The metabolic analysis on sugars consumption revealed the importance of galactose degradation on the final product quality. The analytical methods here described are useful for a rapid evaluation of the maturation process and the quality of blue-cheeses
