Obsidian from the Neolithic Layers of “Grotta di San Michele Arcangelo di Saracena” (Cosenza), Italy. A Preliminary Report

2021

Abstract The paper presents the results obtained by techno-typological analysis of a lithic assemblage from the Neolithic layers of Grotta San Michele Arcangelo di Saracena (Cosenza) together with the results of micro-wear analysis obtained from a preliminary selection of obsidian artifacts with different provenances distinguished by pXRF analysis. The site provides one of the best preserved Neolithic sequences in the area, from the earliest Impressed Wares (or Impresse Arcaiche) (early sixth millennium BC) to the Spatarella pottery style (end fifth – early fourth millennium BC). Along the Neolithic sequence, it is possible to observe some major changes within lithic resources management. I…

Early pastoral communities in the mountains of Sicily. Prehistoric evidence from Vallone Inferno (Scillato) in the palaeoenvironmental framework of t…

2021

Abstract This paper discusses the Middle Neolithic and the Early Bronze Age phases of the occupation of a rock shelter at Vallone Inferno (Scillato, Palermo) in Sicily. Vallone Inferno is a key site for studying the early establishment and development of pastoralism in the prehistoric mountainous environments of Sicily. Seasonal use of the site as a shelter is documented for the earliest pastoral communities that exploited the Madonie mountain range. The results of the analysis of pottery and lithic assemblages contribute to the definition of two chronocultural frameworks that were linked by the same economic subsistence base. The special role of obsidian emerges, while the mobility pattern…

Experiments and results on obsidian tools: the case study of Le Rocche (Roccapalumba, Pa, Sicily) through microwear analysis.

2003

The results of the experimental activity related to the functional analysis of obsidian tools, coming from the Neolithic site of "Le Rocche" (Roccapalumba, Palermo), are discussed here.

The role of a monthly active surveillance programme for multidrug-resistant Gram-negative bacteria in a neonatal intensive care unit: impact evaluati…

2020

Background: Antimicrobial resistance is a public health threat. Neonatal Intensive Care Unit (NICU) patients are particularly at risk, due to the large use of invasive devices and antimicrobial treatment. Since 2014 an active surveillance program of multidrug-resistant organisms is in place in the five NICUs of Palermo, Italy. High prevalence of multidrug-resistant Gram-negative bacteria (MDR-GNB) carriage observed in one NICU suggested the need of a long-lasting approach to achieve effective control of MDR-GNB circulation. Materials/methods: Rectal swabs were obtained every month from each hospitalized new-born. Samples were enriched in liquid cultures, plated in McConkey Agar with three a…

An exceptional rocky shore preserved during Oligocene (Late Rupelian) transgression in the Upper Rhine Graben (Mainz Basin, Germany)

2012

The Early Oligocene (Late Rupelian) Alzey Formation (Mainz Basin, Upper Rhine Graben, Germany) records the development of a rocky coast depositional system during transgression. The formation unconformably overlies Permian bedrock across a composite transgressive ravinement surface. Exposure of the surface shows a succession of subplanar bedrock terraces, separated by near-vertical risers. Terraces show a broad staircase geometry and display wave-erosional features (notches, sea stacks, furrows). Detailed sedimentological and palaeoecological investigations reveal prograding beachface and shoreface depositional units that overlie terraces and are adjacent to risers. Terraces are interpreted…

La garantía social y la autoejecución del derecho al trabajo: La España post-crisis (2007-2017)

2017

What happens when neither the institutions nor the official law are able to cover the basic needs of subsistence and a decent life of an individual or group of people? Do they have, in these situations, a right to self-enforceability of rights? This article will analyze this issue and the main debates associated with it, focusing on the different experiences and types of self-enforceability of the right to work that have occurred in Spain during the last years following the 2007-2008. In particular, it will be analyzed different cases of factory recovery and land occupation and self-management looking at the differences between these two forms of self-executing of the right to work.

The Early Spörer Minimum – A Period of Extraordinary Climate and Socio-economic Changes in Western and Central Europe

2016

Abstract. Throughout the last millennium, mankind was affected by prolonged deviations from the climate mean state. While periods like the Maunder Minimum in the 17th century have been assessed in greater detail, earlier cold periods such as the 15th century received much less attention due to the sparse information available. Based on new evidence from different sources ranging from proxy archives to model simulations, it is now possible to provide an end-to-end assessment about the climate state during an exceptionally cold period in the 15th century, the role of internal, unforced climate variability and external forcing in shaping these extreme climatic conditions, and the impacts on an…
