El document és el resultat d'una investigació més àmplia sobre la construcció de l'Arc Mediterrani. El seu objectiu és posar en relleu el notable grau de desenvolupament de la cooperació regional en la matèria, a través d'una anàlisi detallada de les diferents figures institucionalitzades de cooperació territorial existents (o haver existit) a la zona. L'anàlisi s'ha dut a terme des d'un punt de vista temàtic, basat en els objectius prioritaris d'aquestes institucions. En concret, les xifres estudiades es limiten a les institucions formals o les associacions de col · laboració de caràcter específic, com ara euroregions o les agrupacions europees d'interès econòmic, entès com les figures de major institucionalització dels espais transnacionals a nivell europeu. En canvi, hem deixat de banda altres figures, com Interreg (finançat pel FEDER), ja que no són entitats correctament. Encara que de vegades els acords de cooperació establerts per als projectes d'Interreg han donat lloc a algunes de les entitats estudiades aquí.

La subsidiarietat és el principi filosòfic que es nodreix de diferents fonts teòriques. Una de les definicions més comunes és la que sosté que la presa de decisions s'ha de fer el més a prop possible dels ciutadans de manera que els nivells superiors de govern s'ocupin només del que els nivells inferiors no estiguin en condicions de dur a terme eficaçment per si sols. Partint d'aquesta premissa, aquest treball es divideix en tres apartats. El primer repassa l'evolució del principi de subsidiarietat a la UE des del Tractat de Maastricht. El segon analitza el debat que va tenir lloc a la Convenció Europea voltant d'aquest principi i la proposta final recollida en el projecte de Tractat Constitucional. El tercer i últim estudia les implicacions institucionals que podrien derivar d'aquesta per les regions amb competències legislatives i, en particular, per les Comunitats Autònomes

In this paper, we perform a societal and economic risk assessment for debris flows at the regional scale, for lower Valtellina, Northern Italy. We apply a simple empirical debris-flow model, FLOW-R, which couples a probabilistic flow routing algorithm with an energy line approach, providing the relative probability of transit, and the maximum kinetic energy, for each cell. By assessing a vulnerability to people and to other exposed elements (buildings, public facilities, crops, woods, communication lines), and their economic value, we calculated the expected annual losses both in terms of lives (societal risk) and goods (direct economic risk). For societal risk assessment, we distinguish for the day and night scenarios. The distribution of people at different moments of the day was considered, accounting for the occupational and recreational activities, to provide a more realistic assessment of risk. Market studies were performed in order to assess a realistic economic value to goods, structures, and lifelines. As terrain unit, a 20 m x 20 m cell was used, in accordance with data availability and the spatial resolution requested for a risk assessment at this scale. Societal risk the whole area amounts to 1.98 and 4.22 deaths/year for the day and the night scenarios, respectively, with a maximum of 0.013 deaths/year/cell. Economic risk for goods amounts to 1,760,291 ?/year, with a maximum of 13,814 ?/year/cell.

En este trabajo se construyen algunos indicadores de desempeño para los sistemas educativos no universitarios de las regiones españolas durante los cursos 2005-06 a 2008-09 a partir de información suministrada por diversas publicaciones del Ministerio de Educación. Estos indicadores permiten ofrecer respuestas a la pregunta de qué comunidades autónomas obtienen los mejores resultados educativos de acuerdo con una serie de criterios de desempeño definidos con claridad que recogen tanto aspectos de proceso (acceso a, éxito en y duración de los distintos ciclos educativos) como de resultados medidos en términos de la adquisición de conocimientos. Con el fin de poder hacer comparaciones válidas entre sistemas educativos que se enfrentan a circunstancias muy diversas, hemos construido también indicadores de valor añadido depurando los índices brutos de desempeño de los efectos de dos variables externas que tienen un fuerte impacto sobre los mismos: la disponibilidad de recursos económicos y el nivel educativo de las familias, aproximado por el número medio de años de escolarización de la población adulta.

This paper argues that the current Spanish system of regional financing does not adequately respect the principles of equality, autonomy, responsibility and transparency that should guide its design. It also advances a series of recommendations for the reform of the system that can be classified into two broad headings: guaranteeing the effective application of the constitucional principle of equality and reinforcing the fiscal responsibility and the accountability of regional governments.

A metasomatic diopside rock occurs at the top of the dolomitic Connemara Marble Formation of western Ireland and contains titanite and K-feldspar in addition to around 90% diopside (X(Mg) = 0.90-0.97). U-Pb isotopic measurements on this mineral assemblage show that the titanite is both unusually uranium-rich and isotopically concordant, with the result that a precise U-Pb age of 478 +/- 2.5 Ma can be determined. The age is identical within error to a less precise Rb-Sr age of diopside-K-feldspar of 483 +/- 6 Ma. Petrological evidence indicates that the assemblage crystallized at c. 620-degrees-C close to or below the closure temperature of titanite. The age thus provides a precise estimate of the time of metamorphism; this age is 11 +/- 3 Ma younger than the 490 Ma age for nearby gabbroic plutons which has previously been used to constrain the peak metamorphic age. This difference accords well with geological evidence that the gabbros were emplaced prior to the metamorphic peak. Analysis of minerals with high closure temperature from assemblages whose crystallization is unambiguously associated with a specific episode of fluid infiltration at the peak of metamorphism provides the basis for a new approach to dating metamorphism. The success of this approach is demonstrated by the results from Connemara.

INTRODUCTION AND AIMS: This study investigated the associations of alcohol outlet density with specific alcohol outcomes (consumption and consequences) among young men in Switzerland and assessed the possible geographically related variations. DESIGN AND METHODS: Alcohol consumption and drinking consequences were measured in a 2010-2011 study assessing substance use risk factors (Cohort Study on Substance Use Risk Factors) among 5519 young Swiss men. Outlet density was based on the number of on- and off-premise outlets in the district of residence. Linear regression models were run separately for drinking level, heavy episodic drinking (HED) and drinking consequences. Geographically weighted regression models were estimated when variations were recorded at the district level. RESULTS: No consistent association was found between outlet density and drinking consequences. A positive association between drinking level and HED with on-premise outlet density was found. Geographically weighted regressions were run for drinking level and HED. The predicted values for HED were higher in the southwest part of Switzerland (French-speaking part). DISCUSSION AND CONCLUSIONS: Among Swiss young men, the density of outlets and, in particular, the abundance of bars, clubs and other on-premise outlets was associated with drinking level and HED, even when drinking consequences were not significantly affected. These findings support the idea that outlet density needs to be considered when developing and implementing regional-based prevention initiatives.

Résumé Le but de cette étude est d'évaluer la faisabilité et l'efficacité d'un traitement des carcinomes pharyngo-laryngés avancés par combinaison de chimiothérapie intensive associé à une radiothérapie accélérée. Vingt-trois patients ont été inclus (age médian 54 ans, entre 35 et 70 ans). Les localisations tumorales étaient l'hypopharynx (n=7), base de langue (n=10), nasopharynx (n=2) ou l'oesophage proximal (n.1), ou sans porte d'entrée (n=3). Le traitement comprend trois cycles de chimiothérapie (cisplatin 100mg/m2 à J1 ; 5-FU 1000mg/m2 par jour pendant 5 jours en perfusion continue, précédé par de l'amifostine 910mg/m2 ; répété toutes les trois semaines). La radiothérapie concomitante, accélérée (dose totale de 70Gy en 6 semaines) a été débuté au premier jour du deuxième cycle de chimiothérapie. Vingt et un patients ont pu achever la radiothérapie. Dix-huit patients étaient en rémission complète à la fin du traitement. Avec un suivi médian de 45 mois, le taux de survie globale atteint 56% (95% Cl, 32-79%). Le contrôle loco-régional était de 71% (95% CI, 52-91%). La toxicité associée au traitement consistait en une insuffisance rénale réversible (≥grade II) chez 9 patients (43%) et une agranulocytose fébrile chez 9 patients (43%). Tous les patients ont présenté une mucite modérée à sévère (grade II/III) et 19 patients ont montré une toxicité cutanée de grade III. En conclusion, le traitement combiné de radiothérapie accélérée avec une chimiothérapie concomitante à base de Cisplatin/5-FU full-dose avec amifostine est faisable. La toxicité est importante mais reste maîtrisable dans le cadre d'un centre multidisciplinaire. Le taux de survie globale à 4 ans est prometteur, la recherche en vue de traitements moins toxiques doit se poursuivre. Abstract The purpose of this study was to evaluate the feasibility and efficacy of a treatment concept combining three cycles of full-dose chemotherapy (CT) with concomitant accelerated uninterrupted radiotherapy (RI). Twenty- three patients (median age: 54 years, range: 35-70) with locally advanced squamous cell carcinoma of the head and neck (SCCHN) were included. The primary tumor involved the hypopharynx (n=7), base of the tongue (n=10), nasopharynx (n=2) or upper esophagus (n=1) or its location was unknown (n=3). Treatment consisted of three cycles of chemotherapy (cisplatin 100 mg/m2 on day 1; 5-FU 1,000 mg/m2 per day for 5 days as a continuous infusion, preceded by amifostine 910 mg/m2). repeated every 3 weeks. Uninterrupted concomitant boost-accelerated RI (total dose of 70 Gy in 6 weeks) started together on day 1 of the second cycle. All but two patients received the full course of RT. Eighteen patients achieved complete remission (78%). At a median follow-up of 45 months the overall survival was 56% (95% c.i. 32-79%) and the loco-regional control 71% (95% c.i. 52-91%). Toxicity involved reversible renal insufficiency of grade II in 9 patients (39%) and neutropenic fever in 9 patients (39%). All patients suffered from moderate to severe mucositis (grade HMI), and 19 patients presented cutaneous toxicity grade III. Concomitant boost-accelerated RI combined with concurrent full-dose cisplatin/5-FU chemotherapy and amifostine is feasible with manageable, although substantial, toxicity. The overall survival of 4 years is promising. Newer regimens causing less acute mucosal and skin toxicity are needed.

A first assessment of debris flow susceptibility at a large scale was performed along the National Road N7, Argentina. Numerous catchments are prone to debris flows and likely to endanger the road-users. A 1:50,000 susceptibility map was created. The use of a DEM (grid 30 m) associated to three complementary criteria (slope, contributing area, curvature) allowed the identification of potential source areas. The debris flow spreading was estimated using a process- and GISbased model (Flow-R) based on basic probabilistic and energy calculations. The best-fit values for the coefficient of friction and the mass-to-drag ratio of the PCM model were found to be ? = 0.02 and M/D = 180 and the resulting propagation on one of the calibration site was validated using the Coulomb friction model. The results are realistic and will be useful to determine which areas need to be prioritized for detailed studies.

OBJECTIVE: Little is known about the influence of different training types on relative fat mobilization with exercise. The purpose of this study was to analyze the changes induced by aerobic training (AT), resistance (RT) or a combination of both (AT+RT) on total fat mass (TFM) and regional fat mass (RFM). Further, the relative contribution of different regions, upper limbs (UL), lower limbs (LL), and trunk (Tr), were compared. DESIGN AND METHODS: Forty-five overweight and premenopausal women were randomized in either AT, RT or AT+RT. All training groups exercised for the same duration (60 min), 3 times per week for 5 months. Body composition was estimated using dual energy X-ray absorptiometry. RESULTS: TFM decreased significantly in all groups (-4.6 ± 1.9 kg; -3.8 ± 2.6 kg, and -4.7 ± 3.0 kg in AT, RT, and AT+RT groups respectively; P < 0.001). The relative contribution of FM into each segment changed significantly: TrFM represented 46.6% ± 5.8% of TFM at baseline and reduced to 43.1% ± 5.5% (P < 0.001); LLFM was 39.7% ± 5.8% vs. 41.6% ± 5.7% (P < 0.01); ULFM was 11.3% ± 1.3% vs. 12.2% ± 1.4% (P < 0.01). CONCLUSION: Training type did not influence changes of TFM and RFM. Fat mobilization came predominantly from Tr in all training protocols. These findings suggest that overweight and obese women can reduce TFM and RFM, independently of training type.

Methicillin-resistant Staphylococcus aureus (MRSA) is a major cause of nosocomial infections worldwide. To differentiate reliably among S. aureus isolates, we recently developed double locus sequence typing (DLST) based on the analysis of partial sequences of clfB and spa genes. In the present study, we evaluated the usefulness of DLST for epidemiological investigations of MRSA by routinely typing 1242 strains isolated in Western Switzerland. Additionally, particular local and international collections were typed by pulsed field gel electrophoresis (PFGE) and DLST to check the compatibility of DLST with the results obtained by PFGE, and for international comparisons. Using DLST, we identified the major MRSA clones of Western Switzerland, and demonstrated the close relationship between local and international clones. The congruence of 88% between the major PFGE and DLST clones indicated that our results obtained by DLST were compatible with earlier results obtained by PFGE. DLST could thus easily be incorporated in a routine surveillance procedure. In addition, the unambiguous definition of DLST types makes this method more suitable than PFGE for long-term epidemiological surveillance. Finally, the comparison of the results obtained by DLST, multilocus sequence typing, PFGE, Staphylococcal cassette chromosome mec typing and the detection of Panton-Valentine leukocidin genes indicated that no typing scheme should be used on its own. It is only the combination of data from different methods that gives the best chance of describing precisely the epidemiology and phylogeny of MRSA.
