“To ‘seafood’ or not to ‘seafood’?” An isotopic perspective on dietary preferences at the Mesolithic-Neolithic transition in the Western Mediterranean

2018

Abstract Stable isotope investigations of the Prehistory of the Western Mediterranean have increased exponentially during the last decade. This region has a high number of Mesolithic and Neolithic carbon and nitrogen isotope ratio data available compared with other world areas, resulting from the interest in the “transition” between hunter-gathering and farming. This type of analysis is important as one of the few tools that give direct information on the poorly understood dietary transition from hunter-gatherer to agro-pastoralist subsistence in the Mediterranean Basin. Carbon and nitrogen stable isotope analysis on bulk collagen are especially useful for exploring marine vs. terrestrial p…

Modelling dendro-anthracological parameters with dendrochronological reference datasets: interrogating the applicability of anthraco-typology to asse…

2020

International audience; Aleppo pine (Pinus halepensis Miller) is present in the palaeoenvironmental records of Mallorca (Balearic Islands, Western Mediterranean) since the Early Holocene. It is also documented in the archaeological charcoal analysis (aka anthracology) of early prehistoric sites, but it was especially exploited at certain sites during the Late Iron Age. However, different woodland exploitation strategies cannot be deciphered purely through the taxonomical identification of charcoal fragments, so it is difficult to assess if the presence of Aleppo pine in archaeological assemblages is due to specific social management strategies (branches and/or trunks exploitation). Anthraco…

Libere di scegliere? L'aborto delle donne migranti in Italia tra politiche migratorie, sfruttamento lavorativo e casi estremi di abusi e violenze

2014

The essay take into account the increase in the number of abortion among migrant women in Italy in the wider context of the living conditions of these women which are often subjected to a multiple discrimination related to gender, migrant status, and kind of job. The feminization of migrations towards Italy is put in connection with the feminization of the labour market and with the arrival of specific nationalities of migrants. After having compared the data related to the abortion with respect to Italian and migrant women, this contribution enter into the details of the socio-economic characteristics of these second ones’ life, by analyzing the bond existing with the recourse to abortion.…

Exploiting for Care: Trafficking and Abuse in Domestic Work in Italy

2017

ABSTRACTCare workers are now an essential part of reality for many Italian families. Yet, despite advancements in regulating domestic work, abuses are widespread. This article explores why exploitation in domestic work is rarely viewed as such and addressed with policies concerning trafficking and exploitation. I look at the way in which the care issue has been addressed by the Italian state and at the peculiar relationship between employers and domestic workers. Furthermore, I focus on the gaps in policies on trafficking and exploitation. I argue that the interplay of these factors results in the “normalization” of exploitation in domestic work.

Macrofungi as ecosystem resources: Conservation versus exploitation

2013

Fungi are organisms of significant importance not only for the crucial roles they undertake in nature but also for many human activities that are strictly dependent on them. Indeed, fungi possess fundamental positions in ecosystems functioning including nutrient cycles and wood decomposition. As concerns human-related activities, edible and non-edible mushrooms are also involved and/or exploited in forestry, pharmaceutical industry and food production; hence, nowadays they represent a major economic source worldwide. In order to maintain and improve their strategic importance, several conservation strategies, such as habitat preservation, are needed. This article reports several contributio…

Learning from foreign operation modes: The virtuous path for innovation

2020

In this article, we analyze the impact of learning from internationalization on small and medium enterprises’ (SMEs) performance along different development paths. Drawing on the exploitation versus exploration logic, we use an alternative view of foreign operation modes (the learning perspective) to provide insights into the impact of such learning on technological and organizational innovation as well as overall performance. Our results, which are derived from a sample of 132 SMEs active in traditional manufacturing industries, point to a path to superior performance that entails resource-augmenting operation modes and organizational innovation.

Functional ecological patterns and the effect of anthropogenic disturbances on a recently restored Mediterranean coastal lagoon. Needs for a sustaina…

2012

Abstract We present here a detailed case study on the lessons learned after a restoration process of a natural ecosystem, which can be considered as an ecological experiment. Senillar de Moraira is a brackish water small coastal lagoon located in the Spanish Mediterranean coast. It is separated from the sea by a sand bar and a beach, and is regularly fed by groundwater. Mostly due to the strong anthropogenic pressure this lagoon was degraded, and a restoration process, consisting mostly on the rebuilt of hydrogeomorphological features, was accomplished about a decade ago. After the restoration project, ecological monitoring was performed to reveal the recovery of the ecological integrity of…

Mumijo traditional medicine: fossil deposits from Antarctica (chemical composition and beneficial bioactivity)

2008

Mumijo is a widely used traditional medicine, especially in Russia, Altai Mountains, Mongolia, Iran Kasachstan and in Kirgistan. Mumijo preparations have been successfully used for the prevention and treatment of infectious diseases; they display immune-stimulating and antiallergic activity as well. In the present study, we investigate the chemical composition and the biomedical potential of a Mumijo(-related) product collected from the Antarctica. The yellow material originates from the snow petrels,Pagodroma nivea. Extensive purification and chemical analysis revealed that the fossil samples are a mixture of glycerol derivatives.In vitroexperiments showed that the Mumijo extract caused in…

Taxonomic identity, geographic distribution and commercial exploitation of the culinary-medicinal mushroom Pleurotus nebrodensis

This work provides an updated overview of an investigation carried out in Europe and elsewhere on the culinary-medicinal mushroom Pleurotus nebrodensis. In particular, the taxonomic identitiy of P. nebrodensis and other related oyster mushrooms with entirely white to cream basidiomata that grow on different plants of the family Apiaceae, is clarified. The differences in the cultivation techniques, the quality of product sold and the sales price in Europe and Asia are also highlighted. Taking also into consideration the importance of P. nebrodensis from the medicinal point of view, it appears appropriate to proceed with a verification of the commercial strains currently available in the inte…

Ecological role and exploitation of Posidonia oceanica in the Mediterranean area

2018

The paleoendemic seagrass Posidonia oceanica (L.) Delile (Posidoniaceae) represents a key species of the most important and productive ecosystem in subtidal habitats of the Mediterranean Sea. This species is the most common seagrass in Sicily where it forms dense and extensive beds, which are characterized by high coverage and primary production values, along the Western coasts. According to phenological processes, the beaching of P. oceanica residues (banquette) represents a great environmental, economic, social and, hygienic problem, conflicting with a number of activities (tourism, bathing establishments, etc.). Even though seagrasses play a fundamental ecological role in limiting coasta…
