Influenza della spugnatura sulle caratteristiche sensoriali del Puzzone di Moena
No full textIl “Puzzone di Moena”, tipico delle valli trentine di Fiemme e Fassa è un formaggio prodotto con latte crudo intero o leggermente scremato, semiduro semicotto. La peculiarità del processo di produzione consiste nel trattamento della crosta durante la stagionatura con spugnature periodiche di salamoia diluita, che conferisce al formaggio caratteristiche sensoriali particolari tipiche dei formaggi a crosta lavata.
Nella presente sperimentazione sono state confrontate, da un punto di vista microbiologico e sensoriale, forme sottoposte al trattamento classico di spugnatura della crosta con altre, provenienti dalla stessa lavorazione, stagionate normalmente.
I risultati ottenuti non hanno evidenziato differenze significative per quanto riguarda il profilo microbiologico, mentre differenze più marcate si sono avute da un punto di vista sensoriale per quanto riguarda gli aspetti visivi ed una maggiore varietà dei descrittori di aroma ed odore.
La spugnatura si è dimostrata una tecnica necessaria a caratterizzare questo prodotto e renderlo unico nel panorama dei formaggi italiani
Coagulation properties and Nostrano di Primiero cheese yield of milk from Brown grazing cows of different k-casein genotype
Full text linkProprietà di coagulazione e resa in Nostrano di Primiero del latte di vacche Brune al pascolo con differente genotipo per la k-caseina – Il latte prodotto in alpeggio da 16 bovine di razza Bruna Italiana con diverso genotipo per la k-caseina, 8 AA e 8 BB, è stato analizzato per composizione e caratteristiche reologiche. Lo stesso latte è stato trasformato in formaggio del tipo Nostrano di Primiero. La composizione del latte e il tempo di coagulazione (r) sono risultati simili tra i due tipi genetici, così come la composizione del siero e la resa in formaggio. Il tempo di rassodamento del coagulo (k20) e la sua consistenza (a30) sono risultati invece migliori per il tipo genetico BB rispetto all’AA (4,2 min vs 7,9 min e 32,9 mm vs 25,2 mm)
Sources of variation of milk rennet-coagulation ability of five dairy cattle breeds reared in Trento province
No full textA total of 506 samples of bulk tank milk from morning and evening milkings were analyzed to assess the milk rennet-coagulation ability. Data from the following dairy breeds reared in 55 herds of Trento province, were available: Holstein Friesian (8 herds), Brown (16 herds), Simmental (10 herds), Rendena (13 herds) and Alpine Grey (8 herds). Minimum and maximum number of samples per herd was 4 and 12, respectively. Traits analyzed were: coagulation time in minutes (R), curd-firming time in minutes (K20) and curd firmness in millimeters (A30). Mean and standard deviation for R, K20 and A30 was: 15.90 ± 3.26, 6.13 ± 2.52 and 24.03 ± 6.95, respectively. Analysis of variance was performed using a GLM procedure (SAS package) in order to study the effect of the following sources of variation: breed, herd, recording season, class of milk yield, fat and protein percentage, acidity, urea, bacterial count, clostridia contamination, somatic cell count, herd average days in milk and herd average age at calving. Breed resulted one of the most important sources of variation analysed; other results will be discussed

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
