Wine and Its Legality-A Survey to Know the Consumer Opinions on the Activities of Sicilian Wine Companies Operating on Lands Confiscated from the Maf…

2014

The current guidelines of the European Union Common Agricultural Policy face the agricultural sector in the position of the backbone for the economic development of rural areas and regions with difficult economic differentiation. The EU Common Agricultural Policy defines agriculture as “multifunctional” and among the different roles and functions expected, there is also the “social function”, defined as the ability that the farm has to generate services with respect to a population with risk of social exclusion. This paper investigated all the agricultural initiatives with social impacts that were carried in the lands confiscated from the organized crime (called mafia), mainly in the South …

Study of the importance of emotional factors connected to the colors of fresh-cut cactus pear fruits in the consumer purchase choices for a marketing…

2013

The cactus pear has always aroused curiosity because of its shape and its particular structural characteristics (plate and spiny clatodes, oval fruits of different colors and flowers of an enchanting beauty). This plant evocates the territory where it grows, characterized by a sub-tropical climate, which in Europe is represented by the region of Sicily, the island of the Southern Italy, that is one of the main producers in the Mediterranean area. Sicily has three native cultivars with different colors of the fruit: red, yellow and white. The variety with the yellow fruit is the most widespread, although all of them are commercialized. The chromatic variety of these fruits is one of the stre…

A new approach in the monitoring of the phytosanitary conditions of forests: the case of oak and beech stands in the Sicilian Regional Parks.

2016

The objective of this study was to investigate the health conditions of oak and beech stands in the three Regional Parks of Sicily (Etna, Madonie and Nebrodi). A total of 81 sampling areas were investigated, 54 in oak stands and 27 in beech stands. The phytosanitary conditions of each tree within the respective sampling area was expressed with a synthetic index namely phytosanitary class (PC). Oak stands showed severe symptoms of decline, with 85% of the sampling areas including symptomatic trees. In general, beech stands were in better condition, with the exception of Nebrodi Park, where trees showed severe symptoms of decline. On oak trees, infections of fungal pathogens were also observe…

Il controllo degli insetti fitofagi nell'olivicoltura biologica.

2016

Puntuali strategie di controllo, campionamenti personalizzati e maggiore consapevolezza entomologica, insita nell’approccio del coltivatore biologico, consentono ottimi risultati quali-quantitativi ed economici nella difesa fitosanitaria in olivicoltura “organica” e in qualsiasi area olivicola italiana. Le minori spese fitosanitarie rispetto all’olivicoltura convenzionale inducono un sempre maggior numero di produttori alla conversione verso il bio. Gli autori illustrano le metodologie ammesse e consigliabili in regime di agricoltura biologica, per il controllo dei principali insetti fitofagi del olivo nel Mediterraneo, con particolare riferimento alla mosca delle oilve, Bactrocera oleae, e…

Biodeterioration

2022

The biodeterioration of organic and inorganic materials, as well as polymers, is a complex of alteration processes induced by the growing and metabolic activity of organisms. It can be recognized on monuments, wall paintings, stone, wood, paper, vegetal/animal fibers, and parchment artworks. As defined by Hueck, 1968, biodeterioration is “any undesirable change in the properties of a material caused by the vital activities of organisms”; this definition is accepted as the meaning of the phenomenon. Both macroorganisms (such as animals, plants, and mosses) and microorganisms (such as autotrophic or heterotrophic bacteria, microfungi, cyanobacteria, algae, and lichens) represent the triggers …

Spatio-temporal composition of discard associated with the deep water rose shrimp fisheries (Parapenaeus longirostris, Lucas 1846) in the south-centr…

2017

Discarding in fisheries is the fraction of the total catch brought on board and returned to the sea dead or alive for legal or economic reasons. The reduction of discard is one of the main objectives of the European Common Fishery Policy. This study aimed to improve the current knowledge of the discard associated with the deep-water rose shrimp (DPS) fisheries in the south-central Mediterranean Sea. We analyzed data collected from January 2009 to December 2013. Multivariate data analysis and generalized additive models (GAMs) were used to assess the spatio-temporal composition of the discard (which represented 36% of the total catch) and factors influencing its distribution. Multiple analys…

SAMPLING DESIGN IN SHARE WAVE 7

2019

This chapter documents the sampling design adopted in SHARE. Starting with a definition of the SHARE target population, we describe the protocol that is followed to harmonise and document the sampling procedure and present the sampling frames used by the countries that recruited a baseline or refreshment sample in Wave 7. We then discuss some important aspects of the SHARE sampling design, such as stratification, clustering, variation in selection probabilities and sample composition. Finally, we provide additional information about the sampling variables included in the released SHARE dataset.
