Sicani-telling: storie minute dai margini della Sicilia
No full textThis article tells some stories from the Sicani inner area, in Sicily. Drawing on the considerable debate that in recent years – particularly after the National Strategy for Inner Areas, launched in 2012 – has flourished, this article aims to contribute to the deconstruction of the aestheticizing visions that invest these territories. In particular, the narcotized image of the bourg is critically considered: a discursive and political tendency that underlies selective and pacified imaginaries. Following the idea that small stories produce the world, the article describes some narratives collected during an experiential guided tour through walking research methods. This storytelling is analyzed asking what discourse is produced on these marginal places. As a result, the small stories are a mode of the geographic discourse: a method in doing geography with an embodied and affective approach
Dalla remoteness all’attrattività turistica. Un’analisi di discorsi nazionali e locali sulle aree interne
Full text linkConsidering the processes of territorialization as an interweaving of material and symbolic aspects, the article discusses how the National Strategy for Inner Peripheries has initiated a new season of discourse and intervention on these territories. Based on the Foucauldian concept of discourse, the article analyses the Strategy guidelines, discussing how these territories are signified between a certain vision of peripherality - or remoteness - and of tourist attractiveness. Finally, the discourses of some mayors of the inner peripheries - partly collected in the fieldwork, in the Sicani area in Sicily - are considered to understand how they relate to the imaginary codified by the Strategy
Cultural Democracy, Cultural Ecosystems and Urban Development: Grassroot Initiatives at the Crossroads of Social and Cultural Goals in Bologna
No full textThe paper analyzes the grassroot cultural ecosystem of Bologna in the theoretical framework of cultural democracy and urban development. The first section sets the theoretical framework, grounded on cultural infrastructure, cultural ecologies, cultural democracy and their role in urban development. The second section presents the context of Bologna, the adopted methodology and the findings: it maps grassroot cultural activities with a societal orientation, observes their relevance as places for socialization and as a widespread cultural infrastructure, and analyzes the institutional actions and policy initiatives that sustain this ecosystem. The third section draws conclusions and advocates for a diversified cultural agenda for cities that support the indigenous, grassroot cultural ecology
Investigating the fragmentation pathways of β-naphthol pigments using liquid chromatography/electrospray ionization quadrupole time-of-flight mass spectrometry
No full textRationale: Today, β-naphthol pigments are among the largest and most widely used classes of synthetic organic pigments. Their application fields range from textiles, food and beverages, printing inks, plastics to paint formulations. Most of the research dealing with their study using mass spectrometry focuses on developing sensitive methods for their quantification or their removal from industrial wastewater. Their qualitative recognition in formulations, whose composition is undisclosed by manufacturers, has not been tackled yet. Methods: The collision-induced dissociation fragmentation pathways of 10 red and orange widely used pigments of the late 19th to the early 20th centuries, belonging to the β-naphthol and Naphthol AS classes, were characterized using liquid chromatography/electrospray ionization quadrupole time-of-flight mass spectrometry in negative-ion mode. Results: The fragmentation pathways of these pigments were determined, and the pigments are discussed in relation to their chemical structures. The results were used to determine the composition in terms of the secondary components of one of our reference commercial formulations, characterized by a complex mixture of synthesis by-products. Conclusions: By coupling the high sensitivity of high-resolution mass spectrometry with an efficient chromatographic separation optimized for the analysis of β-naphthol dyes and pigments, we provided a method for the qualitative recognition of this class of molecules in unknown formulations possibly used in different kinds of industrial and synthetic products
Structural social capital and health in Italy
Full text linkThis paper presents the first empirical assessment of the causal relationship between social capital and health in Italy. The analysis draws on the 2000 wave of the Multipurpose Survey on Household conducted by the Italian Institute of Statistics on a representative sample of the population (n = 50,618). Our measure of social capital is the frequency of meetings with friends. Based on probit and instrumental variables estimates, we find that higher levels of social capital increase perceived good health
Myotis dasycneme in a latest Pleistocene bat assemblage of Cittareale cave (Rieti, Latium, Central Italy)
No full textFive species of fossil bats have been discovered in Cittareale cave (Rieti, Latium, Central Italy): Rhinolophus ferrumequinum, R. hipposideros, Myotis (Myotis) myotis, M. (M.) bechsteini and M. (Leuconoë) dasycneme. The presence of a northern “cold” species like M. dasycneme indicates a latest Pleistocene cold phase, probably theYounger Dryas. Cittareale cave is the southernmost site of the past distribution of M. (L.) dasycneme in Europe, which at the present is found as south as northern Croatia
Photo-oxidation processes of Rhodamine B: A chromatographic and mass spectrometric approach
No full textThe study and characterization of organic dyes in textiles, wastewaters, food, cosmetics and forensic specimens is an increasingly important field of research and a challenge for analytical chemistry. Sensitive and specific methods are required to determine molecular markers at very low concentrations and to detect and identify their relative degradation products. In this field, the present paper deals with the development of an extremely sensitive analytical strategy able to identify synthetic organic dyes even after ageing, such as photo-oxidation resulting in severe fading, by identifying specific stable markers. Rhodamine B (C.I. 45,170), belonging to the class of xanthenes, was chosen as representative of fugitive dyes of high commercial and historical importance, in the frame of a research promoted by the European platform IPERION-CH. The behaviour of Rhodamine B used as a dyestuff for wool yarns, subjected to accelerated photo-ageing, was investigated by chromatographic, spectroscopic and high resolution mass spectrometric techniques. The ultra-sensitive analytical method developed, based on core shell reverse phase analytical column separation, allowed us to characterize Rhodamine B oxidation products investigating their mass fragmentation and rationalizing the resulting ageing pathway. These degradation compounds, characterized in artificially aged reference wool yarns, confirmed to be valuable markers for the identification of Rhodamine B even in a complex historical textile matrix as a red Florentine velvet cope subjected to restoration in the 20th century
Investigating the in-solution photodegradation pathway of Diamond Green G by chromatography and mass spectrometry
No full textDiamond Green G (CI 42040, Basic Green 1) is a triarylmethane dye mostly employed in the industrial dyeing of miscellaneous natural and artificial textile fibres, in the production of printing inks and as an anti-fungal agent for aquaculture products. Diamond Green (DG) tends to fade under light irradiation, similar to several other dyes and pigments belonging to the triarylmethane family. In this paper, an in-solution degradation study was carried out to shed light on DG photostability. The experiments were performed by artificially irradiating DG in water and dimethyl sulphoxide, and analysing aliquots sampled at different time intervals by ultra-high performance liquid chromatography coupled with diode array detector quadrupole and time of flight tandem mass spectrometry. The degradation products formed were characterised and the product-ion spectra discussed and interpreted. On the basis of the structure of the identified compounds and their kinetic trend in relation to the accelerated ageing time, degradation mechanisms were proposed for DG, taking into account the role played by the solvent. Finally, the dyeing formulation of an historical textile sample, collected from a stage costume worn in a Zeffirelli lyric opera, was determined utilising the information collected from the analysis of irradiated DG solutions
