Exploring the role of the sharing economy in disasters management
2020
Abstract Improvements in information and communications technologies (ICTs) have facilitated the inclusion of the sharing economy (SE) in societies more than ever. In the aftermath of recent disasters, the SE played significant roles to help the affected people and support official responders. However, the literature has not effectively explored these roles, and thus, no framework can support the systematic inclusion of the SE in disasters management. This paper aims to address the gap through a two-stage exploratory research approach. First, we conduct a systematic literature review to identify the extent to which the SE is taken into consideration in disasters. After that, we investigate …
Environmental quality assessment of the Sicilian coast using a multi-disciplinary approach
2018
A multidisciplinary approach for the assessment of the environmental quality of the Sicilian coast is presented. This approach can be adopted for any Mediterranean coastline. The territory was divided into elementary areas and for each of them we reported the most important taxa, belonging to fauna and vascular, bryophytic and algal flora, from a biogeographic point of view in order to evaluate punctual and general levels of biodiversity conservation. The comparative analysis showed that the main circumsicilian islands and the carbonate promontories of the Tyrrhenian coast present the highest degree of biodiversity. The coastal lagoons located in the south-eastern Sicily, even though charac…
Hypericum scruglii sp. nov. (Guttiferae) from Sardinia
2010
A new species of Hypericum (Guttiferae) from Sardinia, H. scruglii, is described and illustrated. It occurs on damp soil, near springs or streams with freshwater, where it grows with numerous hygrophytes. This diploid species (2n � 16) belongs to the sect. Adenosepalum and is closely related to H. tomentosum, a species widespread in the west Mediterranean region. During field investigations in Sardinia, very peculiar populations of Hypericum L. were found occuring on damp soils and limited to calcareous substrates. These plants showed a close morphological and ecological relationship with H. tomentosum L., a species belonging to sect. Adenosepalum Spach. As emphasized by Robson (1996), the …
New records of Malus crescimannoi (Rosaceae) in Sicily
2016
New findings for Malus crescimmanoi, originally known from the mountain area near Floresta (Nebrodi Mts.). The new sites fall in Madonie Mts., where the species is found at the edge of Quercus petraea (Matt.) Liebl. and Fagus sylvatica woods, growing on quartzarenitic substratum at 1200-1800 m of elevation. These new localities are placed at the south-western limit of Fagus sylvatica distribution area, on both north-facing [Contrada Sempria (Castelbuono) and slopes of Madonna dell’Alto (Castellana Sicula)], and south-facing slopes [Locality Prato (Polizzi Generosa)].
Notulae to the Italian native vascular flora: 9
2020
In this contribution, new data concerning the distribution of native vascular flora in Italy are presented. It includes new records, confirmations, exclusions, and status changes to the Italian administrative regions. Two new combinations are proposed. Nomenclatural and distribution updates, published elsewhere, and corrigenda are provided as Suppl. material 1.
Limonium cophanense (Plumbaginaceae), a new species from Sicily
2016
Limonium cophanense is described and illustrated as a new species from the rocky coast of northwestern Sicily. It is a very rare and localized chamaephyte occurring near the sea on calcarenitic substrate, where it grows together with other halophytes. Its morphology, ecology, conservation status and relationships with the species belonging to the L. bocconei group are also examined.
From microbiota toward gastro-enteropancreatic neuroendocrine neoplasms: Are we on the highway to hell?
2020
AbstractGut microbiota is represented by different microorganisms that colonize the intestinal tract, mostly the large intestine, such as bacteria, fungi, archaea and viruses. The gut microbial balance has a key role in several functions. It modulates the host’s metabolism, maintains the gut barrier integrity, participates in the xenobiotics and drug metabolism, and acts as protection against gastro-intestinal pathogens through the host’s immune system modulation. The impaired gut microbiota, called dysbiosis, may be the result of an imbalance in this equilibrium and is linked with different diseases, including cancer. While most of the studies have focused on the association between microb…
Gut Microbiota, Microbial Metabolites and Human Physical Performance
2021
Trillions of microbes inhabiting the gut modulate the metabolism of the host. Cross-sectional studies have reported associations between physical performance and the gut microbiota (GM). Physical activity seems to increase GM diversity and the abundance of certain health-beneficial microbes. We reviewed the evidence from longitudinal studies on the connection between physically active lifestyle or long-term exercise interventions and the GM. We made literature searches using databases of Web of Science and PubMed Medline to collect human studies showing or not the associations between the GM and exercise. Many controversies exist in the studies. However, the longitudinal studies show that f…
Understanding of tactile pictures in visual impaired children
2015
The present PhD aims at understanding how Visual Impaired (VI) children process the tactile pictures that illustrate the tactile books specially designed for them. Our work is organized around two main axes of analysis. The first axis concentrates on the child who explores the tactile images, while the second axis focuses on the impact that the properties of these images can have on children’s haptic processing. Our researches included children presenting various degrees of visual impairment but without any associated disorders (in particular, without any cognitive delay), distinguishing early blind children from children with low vision. We also compared their performance with those of sig…
IMPORTANCIA DE LA ENFERMERA ESCOLAR EN LA DETECCIÓN DE LA NEOPLASIA TESTICULAR
2011
En este artículo planteamos una revisión de la literatura en diferentes bases de datos (CINAHL, CUIDEN, MEDLINE) con el fin de valorar la importancia de la neoplasia testicular en la adolescencia y el papel fundamental del profesional de enfermería-, concretamente de la enfermera escolar, en la detección precoz de esta patología. Una vez analizado el tema y tras tomar conciencia de la importancia de enseñar prácticas de autoexploración testicular correctas, se ha concluido que la enfermera escolar no debe desarrollar únicamente una actividad asistencial, sino que entre sus funciones se debe contemplar la promoción de la salud y la prevención del cáncer testicular. Dentro del proceso educado…
