Le varietà di grano duro per le semine 2014: Sicilia.

2014

La rete di prove di confronto varietale di grano duro, condotta in Siclia con il coordinamento del CRA-ACM, ha previsto nell’annata 2013-2014 l’allestimento di 4 campi in differenti ambienti: Libertinia (Catania), Catania, Cammarata e S. Stefano Quisquina (Agrigento). Fra le sette varietà al primo anno di valutazione, emergono le performance di Antalis, che ha manifestato ottima capacità produttiva, precocita’ di spigatura, buone caratteristiche merceologiche, contenuto proteico medio e buona resistenza alle malattie.

A Comparative Study of Nonlinear Machine Learning for the "In Silico" Depiction of Tyrosinase Inhibitory Activity from Molecular Structure.

2011

In the preset report, for the first time, support vector machine (SVM), artificial neural network (ANN), Baye- sian networks (BNs), k-nearest neighbor (k-NN) are applied and compared on two "in-house" datasets to describe the tyrosinase inhibitory activity from the molecular structure. The data set Data I is used for the identification of tyrosi- nase inhibitors (TIs) including 701 active and 728 inactive compounds. Data II consists of active chemicals for potency estimation of TIs. The 2D TOMOCOMD-CARDD atom-based quadratic indices are used as molecular descriptors. The de- rived models show rather encouraging results with the areas under the Receiver Operating Characteristic (AURC) curve …

COMPARISON OF EXPERIMENTS WITH WEIGHTED DISTRIBUTIONS

1989

In this paper the standard statistical experiment in which a random sample is drawn from some distribution involving an unknown parameter θ is compared with experiments in which samples are obtained from different weighted versions of that distribution, so that the underlying probability of entering the sample is multiplied by some weight function. This comparison is carried out by means of the concepts of sufficiency and pairwise sufficiency as developed in Blackwell's theory of the comparison of statistical experiments. Many examples are presented which illustrate the wide variety of effects that weight functions can have on the information about θ.

ONLINE SOCIAL COMPARISON ITS ROLE IN PREDICTING INDIVIDUALS’ WELL-BEING

2023

Social comparison is the practice through which people compare their own opinions, abilities, behaviours, and emotions with those of others as an external guide and a source for self-evaluation. Social comparison has been put forward as a core feature of interpersonal relationships both in the offline context and in virtual interactions through social media. A growing number of studies has highlighted that online social comparison through social media can influence individuals’ everyday life. In this thesis, I will examine the role of online social comparison in influencing individuals’ well-being in three research designs with different outcomes. In the first empirical study, a cross-lagge…

Sensory and chemical drivers of wine minerality aroma: An application to Chablis wines

2017

The goal of this work was to evaluate the effect of vineyard position on the minerality of wines and to establish relationships between minerality scores, sensory descriptors and chemical composition. Sensory analyses included minerality rating and free description performed by wine professionals under two conditions: orthonasal olfaction alone and global tasting. Chemical characterization included analysis of major and minor volatile compounds, volatile sulphur compounds, mercaptans, metals, anions and cations. Results showed a significant effect of the river bank on wine minerality scores only in the orthonasal olfaction condition, samples from the left being more mineral than those from …

Characterisation of Vernaccia Nera (Vitis vinifera L.) Grapes and Wine

2017

Vernaccia Nera (VN) is a minor Italian red grape cultivar whose oenological properties have not been investigated yet. Traditional winemaking procedures with VN can include grape drying and even triple sequential fermentations, but a rational vinification approach should be based on the grape composition. Since a comprehensive characterisation of the VN grape is still missing, the ripening of VN grapes was monitored by evaluating flavour compounds, proanthocyanidins and anthocyanins. The grapes were used to produce red wine whose chemical composition and sensory properties were assessed. Ripe VN grapes contained high amounts of extractable anthocyanins (0.88 g/kg). The most abundant anthocy…

Social comparisons at work as related to a cooperative social climate and to individual differences in social comparison orientation

2005

This study examined the frequency of social comparisons in a work setting, and the feelings that these comparisons evoked. These processes were related to individual differences in social comparison orientation, and to the perception of a cooperative social climate at work. The participants were 216 physicians from various health centers in the Community of Valencia in Spain. In general, upward comparisons occurred more often, and elicited more positive and less negative affect than downward comparisons. Those high in social comparison orientation reported relatively more upward as well as downward comparisons, more positive affect after downward comparisons, and more negative affect after …
