Geologia e formaggio di fossa tra Romagna e Marche: caratteristiche geologiche e qualità organolettiche
Full text link“Fossa cheese” is a typical italian product of the Montefeltro area located between Marche and Emilia-Romagna regions. It is different from other cheeses because of its particular phase of maturation, the “infossamento”, that links the cheese to the “Malatestiane” lands of which it is original.
In fact, in this area it is possible to find the typical truncated-cone pits, dug in sandstone rock where, by the XIV century, the people keep food inside in order to save it from the cold winter and from invaders.
The present study aims to analyze the relationship between the geological features of two selected pits (Fossa Talamello - Emilia Romagna, Fossa Cartoceto - Marche) and the physical-chemical, microbiological, nutritional and sensory features of the cheese ripened in these two pits, in order to evaluate whether the ripening environment influence the qualitative features of the final product. Due to the interdisciplinarity of the study, it has been fundamental the collaboration with the “Institute of Food Sciences (ISA-CNR Avellino)”, where the characterization analysis of the cheese were performed, and the “Institute for Coastal Marine Environment (IAMC-CNR Capo Granitola)” that provided some instruments for the acquisition of microclimatic data related to the pits and performed the study and the characterization of the rocks that surround the two pits selected for the study.
In the study, cheeses made from the same milk were used. In particular, a total of 40 quintals of cheese were put in the truncated-cone pits, dug in sandstone rock: 20 quintals in the Fossa Talamello and 20 quintals in the Fossa Cartoceto.
Specific analyzes were conducted starting from milk and followed through the entire production chain up to the final product.
To estimate if the ripening environment (geology of the pits, straw that lines the walls of the pits and microclimate of the pits) influences the qualitative and organoleptic characteristics of the cheese, the microclimate of the two studied areas was monitored in real time and specific analyzes were conducted on rock samples (taken from two sites) and straw that covers the walls of both pits
Planktonic foraminifera response to the azores high and industrial-era global warming in the central-western Mediterranean Sea
Full text linkThe Mediterranean Sea is warming about 20 % more rapidly than global ocean and this phenomenon is
impacting ecosystems and biodiversity. Planktonic foraminifera are an important component of surface and
subsurface water ecosystems and food chains. Their species communities have been altering across the oceans
since the Industrial Era, in response to the ongoing climate change, especially in the western Mediterranean Sea,
where a significant productivity decrease has been recently reported.
Here we show planktonic foraminifera and multispecies stable isotopes from three short sediment cores,
recovered on the eastern flank of the Sicily Channel, central Mediterranean Sea. Results fully confirm the
planktonic foraminifera productivity decrease in the Industrial Era, which is especially relevant for the second
half of the 20th century. The planktonic foraminifera productivity decrease matches with a higher number of
Large Azores High events, i.e., the establishment of an exceptional and persistent winter atmospheric highpressure ridge over the western-central Mediterranean Sea. This is an unprecedented atmospheric phenomenon for the last millennia Mediterranean Sea history, as a direct response of the global warming. Surface productivity and DCM species are especially declining since ~1960 CE, at expenses of winter mixed layer taxa,
suggesting that the Azores High activity prevents a sustained water column vertical mixing and surface water
nutrient fuelling. Our results document and confirm that the climate change has already been affecting Mediterranean marine ecosystems and the basic level of the trophic chain, by extending the surface water stratification period
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
