To evaluate the yield response of two processing tomato hybrids (Ercole and Genius) grown under different irrigation treatments, a field trial was conducted during the 2008 growing season in Southern Italy. Three irrigation treatments were used: the restitution of 70% of maximum evapotranspiration (ETc) both under "Deficit Irrigation" (70DI) and "Partial Root-zone Drying" (70PRD) strategies; full irrigated (FI: 100% ETc). The two water deficit irrigation treatments (DI and PRD) showed stomatal conductance values lower than FI treatment and saved a substantial amount of water maintaining reasonable marketable yield. Moreover, PRD strategy showed slightly higher "Water Use Efficiency" (WUE) values than DI. Finally, "yield response factor" (Ky) showed always values less than unity, indicating the possibility to adopt, within certain limited condition, both DI and PRD in field-grown processing tomato cultivated in Southern Italy. In conclusion, in our experimental conditions, deficit irrigation practices seem to be acceptable relatively to processing tomato yield aspects and Ky could be promoted as a useful indicator for irrigation in water deficit conditions.展开更多

The typical structures of old growth forests infrequently occur in Mediterranean mountainous environments, since they have been affected by human activities for centuries. This study focused on a remote and almost pure Italian maple stand located in southern Italy, which has not been managed for long time due to its inaccessibility. The effects of natural evolution on the forest stand were evaluated through the analysis of the spatial and chronological structure and the regeneration patterns, then estimating the amounts and quality of deadwood occurrence. Across the whole stand, all the trees with DBH (diameter at breast height) larger than 50 cm (LLT, large living trees) were measured (DBH and height) and age was also determined through a dendrochronological approach. The diameters observed ranged between 50 and 145 cm with ages of 12o to ~5o years. The Latham index calculated for trees within the sample plot highlighted a multilayered canopy with a dominant layer of largeliving trees (age 〉 120 years). The size-class distribution of stems had a reverse-J shape, and basal area was 52 m2 ha-1. Deadwood was exclusively constituted by standing dead trees and CWD and its volume was on average 31 m3 ha-1. Pure Italian maple forests are generally rare in Europe, and it was unexpected to find a forest stand characterized by a so complex structure with old growth attributes. The study of complex forest stand, even if small, could give precious information on the forest evolution, clarifying also diverse auto-ecological traits of tree species that usually are not common in our forests.展开更多

The research also aims to demonstrate through previously unknown and unheeded sources that there were not only those English travellers on their Grand Tour of the post-Restoration Bourbon Mezzogiorno (southern Italy) looking for an opportunity of comparing their own civilization (which was considered far superior) to a more fragile reality. There were also other British people who had identified, with a critical eye and spirit of observation, the existence of a Naples and a south Italy which did not merely represent the sum of stereotypes and fallacies handed down through the centuries, and thus refusing the obvious, predictable and false approach given by their own countrymen.展开更多

The choice of Southern Italy, an anti-tourist destination that since the era of the Grand Tour had been considered dangerous for men, let alone for women, magnifies female heroic attitudes and contaminates female conventional domestic purity enhancing the concept of an unfixed female identity. The publication of a travelogue, a mostly non-fictional genre, on an innovative and reactive medium, was a manifest act of transgression with respect to fixed social order, which gave visibility and credibility to a different model of femininity, an anti-Angel icon. A new form of narration displays adventurous women able to cross the private sphere and to write/publish authentic accounts of their transitional experience in a public, male-dominated sphere.展开更多

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 of Italy and especially in Sicily. Through an Italian law, these lands could be used with social purposes by a particular kind of associations which might exercise an agricultural activity with the aim to produce food products, sell them in the market and offer employment opportunities in the agricultural sector. In particular, in Sicily, the activity of the "Social Cooperative Placido Rizzotto-Libera Terra" and its winery "Cantina Centopassi" which received honors and awards tbr its production of wine obtained from the earliest harvests and for its social work in that territory were well known. This work, which was part of a much broader study on "wine and legality", aimed to know the opinion of Sicilian wine consumers and their knowledge about this topic with particular reference to the Cantina Centopassi.展开更多

There are different opinions about the exact period and the steps by which it was brought from its country of origin to the Mediterranean basin where it is cultivated in Corsica, Crete and in southern Italy (Calabria region). In particulary, Citrus medica 'Diamante' grows, almost exclusively, in a restricted area of the Tyrrhenian cost of the region Calabria, called "Riviera dei Cedri", a relevant local economic district. This citron has been and is, still being used by Jews for worship during the Feast of Tabernacles, a very important religious ritual, where it plays a prominent part; in fact, for this holiday of Sukkot, the use of the authentic citron that grows in Calabria region is recommended, because it is not grafted. In this paper, the fascinating history of C. medica and its spread from the centers of origin to the Mediterranean is reported with the aim to investigate the religious and cultural significance of the C. medica 'Diamante', an exclusive and historical heritage of the Calabria region.展开更多

Great numbers of Spaniards, principally the Catalonians, headed to that country. This affected the language, and, in turn, the history of people's last names. At first, some of the Spanish last names were used as nicknames for Italians. The method 1 used to get the data from primary sources was from spending time in Italy for four consecutive summers and visiting towns in the Naples area while I collected surnames found on houses. The Catalonians came to rule Sardinia, and their language and subsequently Spanish were official on the island. The linguistic influence of Spanish does not stop with surnames. A list of Spanish and Basque surnames which is redolent of the history of southern Italy and Sicily is appended. The geolinguistics interest lies in the way that the study of language, both ordinary words and proper nouns, offers important clues to the lives and movements of people of ages past, reflects political and economic aspects and also explains the ethnic origin of people who live in Sicily and Italy today or are descendants of Italians who have been important immigrants in the Americas, in Australia, and indeed around the world.展开更多

In totality, 50 accessions belonging to 14 taxa were collected from 8 collecting sites, representing mainly highly variable old landraces of vegetables and cereals and, especially, of pulses; most of them that appear severely threatened by genetic erosion are still cultivated, at certain level, by old farmers and directly used by their families. A comparison of the results of the previous missions that have been carried out in Calabria region that preserve valuable crop genetic resources on farm shows the large degree of genetic erosion for all crops collected. The results stressed the need to conserve a considerable amount of material endangered and the necessity of our ongoing care for their preservation either on farms or ex situ in genebanks. The complementarity of both conservation methods is needed.展开更多

In this regard the authors examined how the representation of traditions affects place identity and in what ways the cultural heritage of the town might influence environmental forms of behaviour such as plans and projects. To this end the authors investigated the small town of Pagani in southern Italy, which has many ancient cultural traditions linked to specific locations and their rituals such as the festival of Our Lady of the Hens. Our contribution favours a qualitative approach in examining the data gathered and a participative methodology. The statistical analysis of the vocabulary distribution within 83 texts concerning town and its traditions, written by local citizens (52% male and 48% female) of different ages (range: 18-78) revealed a strong place identity. Narrative interviews (14) with key people were then analysed by means of grounded theory. In the perspective of conservation psychology the authors finally focussed on how feelings of impotence and social distrust influence relations between citizens and their local environment.展开更多

Discriminatory treatment of people belonging to a minority group leads to lower wages, and it interferes with their promotions and their productivity. The victims of discrimination are often professionally unvalued, and this can cause their eventual lack of growth for both position and salary, notwithstanding their abilities and creativeness would give a great impulse to the economics. In addition to this, the emotional and physical stress linked to (he concealing strategies of people, who are apt to conceal their homosexuality, increases their feelings of discomfort in the labor market. This paper analyzes the relation between sexual orientation and discrimination in the labor market from the theoretical and empirical points of view. It studies the results of a survey carried out in southern Italy and is based on the sample of 200 gay, lesbian, bisexual, and transgender (GLBT) employees.展开更多

Moreover, the correlations between the analysed parameters were studied. Overall, the results showed that all the honey samples presented high total phenolic and flavonoid contents (12.23 mg gallic acid equivalent/lOOg honey and 8.16 mg quercetin equivalent/lOOg honey, respectively), and a high antioxidant activity (59.17%, 66.50% and 349.11 11M Fe (II) for ABTS, DPPH and FRAP assays, respectively), but those results differ widely according to the honey types, suggesting that honey composition has been influenced by its floral and geographical origin. In particular, the darkest honeys, such as chestnut honey (L * = 59.94; 1.26 AU), showed the highest polyphenol content and the highest antioxidant activity. Honeys from the areas with major anthropogenic activities and high population density presented the highest antioxidant activity. Correlations between the analysed parameters were statistically significant (P 〈 0.05), suggesting that the polyphenol content is correlated with the antioxidant activity and colour of honey.展开更多

The applied formulations were suspension-solutions containing humic and fulvic acids, amino acids and macro elements or amino acids and peptides obtained by chemical hydrolysis of animal epithelium. The following parameters of the quantitative-qualitative of crops were determined: marketable yield, mean weight, dry matter, pH, soluble solids, and color for tomato; grain yield, protein content, gluten content, yellow index and hectoliter weight, for durum wheat; marketable weight, number and surface, dry matter, nitrate content, thickness of leaves for lettuce. The results obtained were generally quite variable.展开更多
