Da marketing intraetnico a marketing interetnico: il commercio straniero agro-alimentare in Provincia di Roma
No full textA Roma, negli ultimi tempi, la crescita di esercizi a conduzione straniera di prodotti agro-alimentari sta conoscendo un sensibile incremento dovuto sia alla presenza sempre più numerosa di cittadini stranieri, sia a mode che influenzano il gusto e richiedono prodotti esotici. L’analisi quantitativa condotta alle diverse scale geografiche dimostra che non si tratta solo di negozi che rientrano nella categoria «etnici» ma, in taluni casi, anche di imprenditori stranieri che gestiscono attività di commercio agro-alimentare del tutto analoghe a quelle dei corrispondenti imprenditori italiani, testimoniando il passaggio da un marketing esclusivamente intraetnico ad uno interetnico.
Il presente contributo prende in esame, in chiave diacronica, le dinamiche territoriali della distribuzione del commercio straniero di natura agro-alimentare, all’ingrosso e al dettaglio, per mettere in luce le forme di concentrazione e di diffusione dell’imprenditoria straniera presenti a Roma e nella provincia
La territorializzazione delle politiche europee: alcune riflessioni sulla nuova politica di coesione

No full textWe turn our attention to an issue that is often not based on rational science, but about fear – the issue of asbestos. As the geological community is well aware, all asbestos are minerals, and thus naturally formed; yet in the public arena the many people believe asbestos is something manufactured by humans and that one fiber is enough to kill you if inhaled. It is our intent to provide the necessary background for members of the scientific community, be they mineralogists, geologists, medical researchers, regulatory workers, or attorneys. This paper contains an introduction and overview of the health effects associated with the inhalation of amphibole minerals. Also, it discusses some of the current issues and research trends surrounding asbestos exposure, especially in the natural environment
Chrysotile, crocidolite, asbestiform erionite: mineralogical characterization and cytotoxic effects
No full textUICC chrysotile, chrysotile from Val Malenco, erionite from Nevada and UICC crocidolite fibers were characterized through Transmission Electron Microscopy (TEM) with annexed Energy Dispersive Spectroscopy (EDS). The TEM study was performed forward on three levels for each single sample.
The first observed aspect was the morphological and dimensional study: typical fibrous morphology was observed for all the analyzed samples. For each sample 100 fibers were investigated: were registered their dimension (length and diameter) and the L/d ratio were calculated in order to understand if the fibers population can entry in particular dimensional categories (e.g. WHO criteria, Stanton’s Hypothesis criteria or EPA dimensional limits).
The second observed aspect was the chemical composition of the fibers. Also the chemistry match well with the expected for this minerals. In particular, both the chrysotile samples show the presence of aluminum and iron as substitute of tetrahedral and octahedral typical cations; the crocidolite bears an adding of calcium and the erionite has magnesium and iron cations normally unexpected in the general formula.
At the latter investigation level, all the fibers showed a high degree of crystallinity in the diffraction patterns study, without evidence of natural amorphization (e.g. weathering).
These characterized mineral fibres were administrated for 6, 12, 24 and 48h in human bronchial and mesothelial cells, at the concentration of 50μg/ml, to evaluate their cytotoxic effects; some biofunctional parameters at time points were evaluated: % number of alive, death and apoptotic cells; % number of cells with low, medium, high ROS content.
These data confirm higher cytotoxic effects exerted by UICC crocidolite and UICC chrysotile, particularly evident since short times of contact (6, 12h).
Our next purpose will be to characterize the same fibers extracted from cells after culture treatments
Stato coniugale e sopravvivenza
No full textFor several decades now, in many countries, marital status has been recognized as a key factor in determining the health and survival of individuals for both men and women, although less markedly so for the latter. The data used in various studies in this area are generally of two types: data coming from census and vital statistics registries, covering the entire population (Gove, 1973; Trovato and Lauris, 1989), and data resulting from surveys (Brockmann and Klein, 2004). In Italy, to our knowledge, there are few studies on the subject and only of the second type (Scafato et al., 2008). In this paper we aim to assess mortality in Italy in 2001 using census data and mortality values for the entire Italian population aggregated by gender and age group (8 age classes from 35-39 years to 70 -74 years). In this paper we aim to assess mortality in Italy in 2001 using census data and mortality values for the entire Italian population aggregated by gender, age group and marital status, which is assumed to be a discriminating factor, presumably along with cohabitation. The present work is the first stage of a larger research project aimed at highlighting the evolution of mortality rates by gender, age and marital status in Italy from 1971 onwards
Ulivi, paesaggio e prodotti tipici come componenti del patrimonio
No full textThe current attitude towards «heritage» is also valid for the concept of «nature» and especially for animate nature. Within it, the «monumental trees» are one of the most meaningful examples of the transformation into heritage. A particularly interesting
case is represented by the «Apulian secular olive trees», which have been
recently protected and promoted by the region Apulia through new rules and regulations.
These rules and laws resulted from a movement of opinion focused on preventing the secular olive trees from being uprooted, trafficked and sold to the regions of Northern Italy. After their nationwide and local recognition, the Apulian secular olive trees are going forward even further, by undergoing a «consecration» of their universal asset value. Along this path it’s worth remembering the registration,
already occurred, to the Representative List of the Intangible Cultural Heritage
of Humanity (2010) of the Mediterranean Diet and it’s also worth mentioning
the recent request to include the editerranean olive-yard landscape among the properties forming part of the World Heritage (Convention UNESCO, 1972)

Donne e salute: le mutilazioni genitali femminili. Per continuare un cammino tra culture e territori
No full textWOMEN AND HEALTH: FEMALE GENITAL MUTILATIONS. TO CONTINUE A JOURNEY BETWEEN CULTURES AND TERRITORIES – Female genital mutilations, named female circumcision according to the vision of traditional practices belonging to specific cultures, as a result of migratory movements have become increasingly involved with the territories of arrival of migrants, especially women migrants, both in conceptual
and operational terms. In recent years the phenomenon has interested organizations and institutions at different geographical scales and the debate must continue: the issue deserves to be treated, not only for the delicate and complex meanings implied, but also for the places, the social actors and local services involved
Turismo, qualità della vita e sviluppo locale
No full textIl turismo postmoderno di massa, troppo spesso, separa le esigenze da soddisfare dalle località che le soddisfano e promuove “non luoghi” o “iperluoghi", trascurando, invece, di promuovere il "tourist gaze" che consiste nel saper cogliere l’individualità e l’identità delle mete e quindi nello scoprire “il gusto della geografia” la quale è particolarmente attenta allo studio delle relazioni e delle differenze tra i luoghi.
È a questo tema che viene dedicato il presente lavoro con il si intende proporre anche qualche contributo allo sviluppo turistico locale collegato ad una sempre migliore qualità della vita e suggerito anche dalla geografia cultural
