Main intrinsic factors driving land grabbing in the African countries’ agro-food industry

2022

Land grabbing is a phenomenon that has spread widely over the last two decades and which involves rich and emerging countries and international companies as protagonists in the large-scale acquisition of land in developing countries. Through the development of an econometric model that takes into account the annual size of land grabbing in the African countries, the research aims to understand the main intrinsic factors, linked to the hosting countries, that guide the large-scale acquisition of land by foreign investors. Results show that the presence of a high debt towards foreign organisations, the high availability of virgin lands, the strong vocation of the hosting country for the culti…

Influence of Variety and Maturity Stage on Sterolic Composition of Virgin Olive Oil from Central-Western Sicily

Olive oil is one of the most important food products throughout the Mediterranean Basin due to its high nutritional and dietetic value. In recent years, there has been increased interest in the sterols of olive oil for their health benefts and their importance to virgin olive oil quality regulation. The impact of sterols on the human health is proved by several studies, showing that a suffcient quantity of β-sitosterol inhibits the intestinal absorption of LDL-cholesterol. In olive oil the phytosterol concentration ranges from 800 to 2600 mg kg-1. Sterol esters evaluation has been proposed as useful parameter in studies related to varietal and geographical discrimination. Cultivar and matur…

Polish Translations of Anglo-American Literature and the Question of Ideology : From Romanticism to Twentieth-Century Avant-Gardes

2017

Ideology has always influenced translation, yet this fact became a topic of scholarly research only in the 1990s. The working of ideology in literary translations most often manifests itself as a conflict of value systems. From vast reservoir of foreign sources, the native axiology absorbs values that it needs to sustain its culture. It is not a coincidence that Anglo-American literature, propagating ideas of democracy and individual freedom, became popular in Poland in the first half of the nineteenth-century when Poland did not exist as a state. Only a century later, American literature was the most popular of all foreign literatures in pre-1939 Poland. World War II changed this situation…

Effect of growing area on tocopherols, carotenoids and fatty acid composition ofPistacia lentiscusedible oil

2014

International audience; In this investigation, we aim to study, for the first time, the effect of the growing area on tocopherols, carotenoids and fatty acid content of Pistacia lentiscus fixed oil. Fruits were harvested from eight different sites located in the north and the centre of Tunisia. Tocopherols, carotenoids and fatty acid content of the fixed oils were determined. The highest carotenoid content was exhibited by Feija oil (10.57 mg/kg of oil). Oueslatia and Tabarka oils displayed the highest alpha-tocopherol content (96.79 and 92.79 mg/kg of oil, respectively). Three major fatty acids were determined: oleic, palmitic and linoleic acids. Oleic acid was the main fatty acid presenti…

Orlando, posterity and textual survival beyond the book

2022

This paper’s premise is that certain texts call for adaptation in the sense that they encapsulate anxieties about their posterity and their survival beyond their current material actualization. Orlando’s musings on death and immortality in Virginia Woolf’s eponymous novel are a case in point as they reflect a conflicted longing for the solidity of commemorative monuments and for the immateriality of memory-scapes. Lying “entombed” and “embalmed” in the medium of the book, words also rise “like an incantation” when brought to life by the reader (Orlando, Penguin Classics, 2000, 57). This passage is to be related to the modernist revival of interest in the works of Sir Thomas Browne which not…

The evolutionary dynamics of adaptive virginity, sex-allocation and altruistic helping in haplodiploid animals

2018

In haplodiploids, females can produce sons from unfertilized eggs without mating. However, virgin reproduction is usually considered to be a result of a failure to mate, rather than an adaptation. Here, we build an analytical model for evolution of virgin reproduction, sex-allocation, and altruistic female helping in haplodiploid taxa. We show that when mating is costly (e.g., when mating increases predation risk), virginity can evolve as an adaptive female reproductive strategy. Furthermore, adaptive virginity results in strongly divergent sex-ratios in mated and virgin queen nests ("split sex ratios"), which promotes the evolution of altruistic helping by daughters in mated queen nests. H…

Effects of variety and olive ripeness on nutritional quality and oxidative stability of extra virgin olive oils

2004

The composition and the stability to oxidative reactions of Italian extra virgin olive oils, in relation to olive varieties and ripeness, have been studied. Nutritional quality has been evaluated comparing nutrient contents with the recommended daily intake for the Italian population. Oxidative vulnerability has been studied following three different approaches: i) a predictive approach (calculation of the degree of antioxidant protection or DAP index); ii) a descriptive approach (loss of some natural antioxidants during storage); iii) a confirmatory approach (oven test method). This study demonstrated that the olive variety and ripeness degree are important determinants of the nutritional …

Oxidation Processes in Sicilian Olive Oils Investigated by a Combination of Optical and EPR Spectroscopy

2012

:  Extra virgin olive oil (EVOO) is recognized as one of the healthiest foods for its high content of antioxidants, which forestall and slow down radical formation. Free radical-initiated oxidation is considered one of the main causes of rancidity in fats and oils. As a consequence, reliable protocols for the investigation of oil oxidation based on selective, noninvasive, and fast methods are highly desirable. Here we report an experimental approach based on UV-Vis absorbance, steady-state fluorescence, and electron paramagnetic resonance (EPR) spectroscopy for studying oxidation processes induced by temperature for a period up to 35 d on Sicilian EVOO samples. We followed the decrease in β…
