Italian Consumers’ Preferences for Pasta and Consumption Trends: Tradition or Innovation?
Full text linkThe aim of this study is to know Italian consumers’ preferences for Pasta and consumption habits. Food culture and concerns about food security and product innovation were investigated. A sample of Italian consumers was interviewed. Consumer’ profile, motivations and purchasing behavior were described. Relationships between observed variables and the latent constructs that explain the preferences were highlighted. There is asymmetric information between consumers and producers. Consumers believe Pasta is made with Italian grains, and therefore it is healthy and safe, although that’s not always the case. Intrinsic and extrinsic high quality, which derives from growing and production technologies, is required
Analisi della produzione e del mercato dei prodotti di IV gamma in Italia
No full textIl volume si articola in due parti: la prima approfondisce l’analisi della produzione e del mercato in Europa, con particolari specificazioni e approfondimenti sulla situazione produttiva e organizzativa esistente in Francia: Paese, come sopra specificato, dove nacque e dov’è più diffuso il comparto della produzione e della commercializzazione dei prodotti di IV gamma; la seconda si diffonde sull’analisi della produzione e del mercato in Italia, con particolare attenzione alla situazione siciliana

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
Planting Date and Different N-Fertilization Rates Differently Modulate Agronomic and Economic Traits of a Sicilian Onion Landrace and of a Commercial Variety
Full text linkThe onion is one of the most widespread bulb vegetables worldwide. Onion cultivation is common in Sicily, as is the use of local genotypes. Cultivation practices are of particular interest in optimizing yield, quality, and profits. The aim of this study was to assess the agronomic response of a Sicilian landrace (Bianca Calda di Comiso, coded L1) and a commercial variety (Bianca di Maggio, coded V1) to different planting dates and N fertilization rates. An economic appraisal was also performed. The two genotypes were assessed using an experimental split-split-plot design with four levels of nitrogen rates (0, 80, 160, and 220 kg N ha−1) and two different planting dates (8 October 2005 to 9 October 2006 for the early planting date, and 27 December 2005 to 30 December 2006 for the traditional planting date). The marketable yield and production parameters were significantly influenced by the nitrogen dose: higher doses led to a higher total yield, with yield peaks above 60 t ha−1 and the marketable yield ranging from 23% to 54%. Simultaneously, decreases in the firmness (from 7% to 19%) and scale content (from 1% to 3%) were also reported. The L1 landrace showed a higher production than the V1 variety. The crop year did not significantly affect the results, and the traditional planting date appeared to be the most suitable choice in obtaining the best agronomic response. Economic analysis showed that the L1 landrace, with high-N application treatments, produced greater net benefits and marginal rates of return. Thus, the L1 landrace exposed to the highest dosages of nitrogen (160 or 220 kg ha−1) and transplanted during the traditional planting period is the best choice from agronomic and economic points of view
Consumer acceptance and primary drivers of liking for small fruits
No full textSmall fruit grow naturally in northern Italy, but also in the Sicilian region
(southern Italy) there are some areas with the essential climatic conditions for the
development of this crop. Nevertheless, according to official statistics, the quantities
of fresh small fruits placed on the Italian market are lower than in other European
countries. The objective of this study was to assess consumer acceptance for sensory
attributes and other intrinsic and extrinsic quality parameters of fresh small fruit, in
order to know the primary drivers of liking and have a first understanding of reasons
for the poor domestic consumption. Six focus groups with sensory test were carried
out to assess consumers’ preferences on four types of small fruits stored for 3 and 5
days at low temperature (5±1°C, 90±3% relative humidity RH). Consumers’
evaluations were also compared with those of a panel of experts for the two periods of
storage. Consumers’ acceptance of sensory attributes after 3 days of storage was very
good and after 5 days was good. Visual appearance and taste were the descriptors
with highest liking both for consumers and experts. Results showed a good
concordance between FG consumers’ evaluations and panellists’ ones, for all
descriptors of berries. These results may be useful for future research to focus on
effective actions in order to enhance berries commercialization
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
