Behavioural profile of drug users attending public drug-treatment centres in Sicily: the role of social context
2007
<p><strong>Objective</strong>: Investigations of injecting drug users (IDUs) have suggested that the social context may influence high-risk behaviours in this population. The aim of this study was to describe knowledge, attitudes and behaviours of IDUs attending public drug-treatment centres in our area.</p><p><strong>Study design and methods</strong>: A cross-sectional survey was conducted between July 2002 and February 2004, enrolling 607 drug users attending four public drug-treatment centres in the Palermo area. Two of them were located inside the urban area, whereas the other two were in rural districts near the city. All participants answered …
An Online Time Warping based Map Matching for Vulnerable Road Users’ Safety
2018
International audience; High penetration rate of Smartphones and their increased capabilities to sense, compute, store and communicate have made the devices vital components of intelligent transportation systems. However, their GPS positions accuracy remains insufficient for a lot of location-based applications especially traffic safety ones. In this paper, we developed a new algorithm which is able to improve smartphones GPS accuracy for vulnerable road users' traffic safety. It is a two-stage algorithm: in the first stage GPS readings obtained from smartphones are passed through Kalman filter to smooth deviated reading. Then an adaptive online time warping based map matching is applied to…
Analysis of documentary and terminological needs of doctors and medical translators as a basis for the development of a next-generation multilingual …
2014
En el presente trabajo se plantea el diseño de un recurso lexicográfico multilingüe orientado a médicos y traductores médicos. En la actualidad, no existe ningún recurso que satisfaga a ambos colectivos por igual, debido a que estos poseen necesidades muy diferentes. Sin embargo, partimos de la premisa de que se podría crear una herramienta única, modular, adaptable y flexible, que responda a sus diversas expectativas, necesidades y preferencias. Se parte para ello de un análisis de necesidades siguiendo el método empírico de recogida de datos en línea mediante una encuesta trilingüe. The objective of this study is to develop a multilingual lexicographical resource aimed at doctors and medi…
Fungal genes related to calcium homeostasis and signalling are upregulated in symbiotic arbuscular mycorrhiza interactions
2012
Fluctuations in intracellular calcium levels generate signalling events and regulate different cellular processes. Whilst the implication of Ca2+ in plant responses during arbuscular mycorrhiza (AM) interactions is well documented, nothing is known about the regulation or role of this secondary messenger in the fungal symbiont. The spatio-temporal expression pattern of putatively Ca2+-related genes of Glomus intraradices BEG141 encoding five proteins involved in membrane transport and one nuclear protein kinase, was investigated during the AM symbiosis. Expression profiles related to successful colonization of host roots were observed in interactions of G. intraradices with roots of wild-ty…
From political controversy to a technical problem? Fifteen years of opioid substitution treatment in Finland
2013
Abstract Background The aim of the article is to analyze changes in opioid substitution treatments (OST) in Finland. OST spread in Finland in the late 1990s and early 2000s (Phase 1). Since then, OST has become an integrated part of Finnish drug policy and is provided in various substance abuse treatment units as well as in municipal health centers (Phase 2). Methods The paper analyses the policy around the implementation of opioid substitution treatment in Finland, focusing on identifying the key factors and the relations between them that have contributed to the implementation of OST in Finland. Results OST has become accepted in Finland during the past ten years as a crucial element of a…
Explaining Internet dependency
2006
PurposeTo analyse key drivers of Internet dependency and its impact on willingness to purchase online.Design/methodology/approachThe applicability of the media dependency scale is tested in the Spanish market. The impact of demographics, Internet exposure, online experience and Internet affinity on Internet dependency is analysed together with behavioural changes deriving from Internet dependency (willingness to purchase online).FindingsData analysis shows that the media dependency scale needs to be adapted to the Spanish market and Spanish Internet users show intermediate levels of Internet dependency. Dependent users are mainly young, highly‐educated, feel Internet affinity and have high …

Fog Computing based traffic Safety for Connected Vulnerable Road Users
2019
Annually, millions of people die and many more sustain non-fatal injuries because of road traffic crashes. Despite multitude of countermeasures, the number of causalities and disabilities owing to traffic accidents are increasing each year causing grinding social, economic, and health problems. Due to their high volume and lack of protective-shells, more than half of road traffic deaths are imputed to vulnerable road users (VRUs): pedestrians, cyclists and motorcyclists. Mobile devices combined with fog computing can provide feasible solutions to protect VRUs by predicting collusions and warning users of an imminent traffic accident. Mobile devices’ ubiquity and high computational capabilit…

Observation of Poincaré-Andronov-Hopf Bifurcation in Cyclotron Maser Emission from a Magnetic Plasma Trap
2018
We report the first experimental evidence of a controlled transition from the generation of periodic bursts of electromagnetic radiation into the continuous-wave regime of a cyclotron maser formed in magnetically confined nonequilibrium plasma. The kinetic cyclotron instability of the extraordinary wave of weakly inhomogeneous magnetized plasma is driven by the anisotropic electron population resulting from electron cyclotron plasma heating in a MHD-stable minimum-B open magnetic trap. peerReviewed
