Characteristics of 2D convective structures in Catalonia (NE Spain): an analysis using radar data and GIS

Flood simulation studies use spatial-temporal rainfall data input into distributed hydrological models. A correct description of rainfall in space and in time contributes to improvements on hydrological modelling and design. This work is focused on the analysis of 2-D convective structures (rain cells), whose contribution is especially significant in most flood events. The objective of this paper is to provide statistical descriptors and distribution functions for convective structure characteristics of precipitation systems producing floods in Catalonia (NE Spain). To achieve this purpose heavy rainfall events recorded between 1996 and 2000 have been analysed. By means of weather radar, and applying 2-D radar algorithms a distinction between convective and stratiform precipitation is made. These data are introduced and analyzed with a GIS. In a first step different groups of connected pixels with convective precipitation are identified. Only convective structures with an area greater than 32 km2 are selected. Then, geometric characteristics (area, perimeter, orientation and dimensions of the ellipse), and rainfall statistics (maximum, mean, minimum, range, standard deviation, and sum) of these structures are obtained and stored in a database. Finally, descriptive statistics for selected characteristics are calculated and statistical distributions are fitted to the observed frequency distributions. Statistical analyses reveal that the Generalized Pareto distribution for the area and the Generalized Extreme Value distribution for the perimeter, dimensions, orientation and mean areal precipitation are the statistical distributions that best fit the observed ones of these parameters. The statistical descriptors and the probability distribution functions obtained are of direct use as an input in spatial rainfall generators.

Temporalidad y contaminacion como claves para interpretar la biodiversidad de macroinvertebrados en un arroyo mediterraneo (Riera de Sant Cugat, Barcelona)

En Octubre de 1995 se estudiaron 10s macroinvertebrados acuaticos en varias localidades de la cuenca de la Riera de Sant Cugat (Barcelona) situadas dentro y fuera del Parque Metropolitan0 de Collserola y, se relacionaron con la calidad y la temporalidad de las aguas. Gran parte del recorrido de 10s cauces estaba sec0 en el moment0 de estudio. Algunas localidades, situadas en 10s limites del Parque, poseian flujo permanente per0 con elevados signos de contaminacibn. Dentro del Parque se encontraron algunas zonas con caudal permanente, aunque reducido (desde menos de 1 V s hasta 32 Us), y zonas con flujo intermitente, ademas de 10s que estaban secos. En las quince localidades muestreadas se encontraron un total de 65 taxones distintos; la mayor riqueza en una sola estacidn fue de 33 y se encontraron tanto especies de zonas redfilas (simlilidos o algunos efemerdpteros) como aquellas m8s propias de aguas 16nticas como hemipteros, odonatos o algunos cole6pteros. Mediante un anhlisis de ordenacidn en el espacio se agruparon las estaciones y se ordenaron en funcibn de su flujo y del grado de polucibn, diferenciindose claramente las estaciones externas al parque (con flujo moderado y cierta contaminacidn) de aquellas situadas en el interior del parque y, entre Cstas, las de flujo permanente respecto a las encharcadas. Se analizaron las diferencias entre estos cuatro grupos segun 10s tipos de organismos existentes y su estrategia trófica. A pesar de que muchos puntos de muestreo presentaban poca agua, se refuerza la idea de la importancia de mantener 1os flujos minimos de estos rios para conservar la biodiversidad.

Plant diversity across five vegetation belts in the Pyrenees (Catalonia, Spain)

In this paper we analyze the size and habitat partitioning of the vascular floras of five areas of the NE Iberian Peninsula, representing five distinct vegetation belts and three floristic regions: Mediterranean (basal belt), medio-European (submontane and montane belts) and Boreo-Alpine (subalpine and alpine belts). Each area covered over 1000 ha, and was fairly uniform in terms of potential vegetation, bedrock and bioclimate. They excluded large villages and field areas, the landscape being mainly natural or moderately anthropized.

Sobre les avellanoses als Pirineus catalans

Els bosquets de Corylus avellana dels Pirineus Catalans representen, malgrat llur fisiognomía uniforme, fases de degradació o de reconstitució de diversos boscos caducifolis. Atenent a aquest fet i a llur composició florística poc específica, sembla convenient de tractar-los com a variants de Corylus del Buxo-Quercetum pubescentis, del Buxo-Fagetum, del Brachypodio-Fraxinetum,... Cal excloure potser d'aquesta generalització L¿Hepatico-Coryletum, comunitat de difícil filiació i caracterització sintaxonómiques, pròpia de l'Alta Cerdanya i del Conflent. I el Scillo-Fagetum actaeo-coryletosum, subass. nova, que representa, igual que el síntàxon anterior, una vicariant de les fagedes en valls internes pirinenques amb clima continentalitzat, mancades de faig.

Use of alternative and complementary therapies in labor and delivery care: a cross-sectional study of midwives" training in Catalan hospitals accredited as centers for normal birth

Background: The use of complementary and alternative medicine (CAM) and complementary and alternative therapies (CAT) during pregnancy is increasing. Scientific evidence for CAM and CAT in the field of obstetrics mainly covers pain relief in labor. Midwives are responsible for labor and delivery care: hence, their knowledge of CAM and CAT is important. The aims of this study are to describe the professional profile of midwives who provide care for natural childbirth in Catalan hospitals accredited as centers for normal birth, to assess midwives" level of training in CAT and their use of these therapies, and to identify specific resources for CAT in labor wards. Methods: A descriptive, cross-sectional, quantitative method was used to assess the level of training and use of CAT by midwives working at 28 hospitals in Catalonia, Spain, accredited as public normal birth centers. Results: Just under a third of midwives (30.4%) trained in CAT after completion of basic training. They trained in an average of 5.97 therapies (SD 3.56). The number of CAT in which the midwives were trained correlated negatively with age (r = - 0.284; p < 0.001) and with their time working at the hospital in years (r = - 0.136; p = 0.036). Midwives trained in CAT considered that the following therapies were useful or very useful for pain relief during labor and delivery: relaxation techniques (64.3%), hydrotherapy (84.8%) and the application of compresses to the perineum (75.9%). The availability of resources for providing CAT during normal birth care varied widely from center to center. Conclusions: Age may influence attitudes towards training. It is important to increase the number of midwives trained in CAM for pain relief during childbirth, in order to promote the use of CAT and ensure efficiency and safety. CAT resources at accredited hospitals providing normal childbirth care should also be standardized.

Prevalence of smoking among dentists in Catalonia - Spain (2006). Literature review of smoking cessation practices in the dental office

Objective: The objective of this study was to collect data on the prevalence of smokers among Catalonian dentists (by age and sex) and compare them with existing data on the general population, doctors, registered nurses and pharmacists. The overall prevalence of smokers in Catalonia (2006) was 34.5% of men and 24.3% of women. Data available on the prevalence of smoking among doctors (26.3% men and 22.1% women), pharmacists (19.8% men and 20.6% women) and registered nurses (34.1% men and 35.3% women) relates to the year 2002. Study design: In September 2006, Catalonian dentists (n=3,799) were asked about their habits in relation to tobacco in a self-administered questionnaire, on use and opinions with respect to dental amalgam. Five hundred and seventynine questionnaires were received, of which 538 answered the question on smoking (14.2% of the sample universe). Results: The prevalence of smokers among dentists is lower (24.9% of men and 18.4% of women) than in the general population and other healthcare professionals. In dentists in the age group between 25 and 34 years, the prevalence was 26.1% in men and 14.9% in women, while the prevalence in this age group in the general population was 43.6% and 37.1%, respectively. Conclusion: Catalonian dentists have a much lower prevalence of tobacco use than the general population and lower even than other healthcare professionals. Given that non-smoking healthcare professionals have better awareness for providing recommendations for smoking prevention and cessation, Catalonian dentists may be a valid group for performing this task for which there is scientific evidence.

Los vertebrados fosiles del Abocador de Can Mata (els Hostalets de Pierola, l'Anoia, CataluÑa), una sucesion de localidades del Aragoniense superior (MN6 y MN7+8) de la cuenca del Valles-Penedes. CampaÑas 2002-2003, 2004-2005

Se presenta una síntesis del registro de vertebrados fósiles del Abocador de Can Mata (els Hostalets de Pierola, cuenca neógena del Vallès-Penedès), con especial énfasis en los aspectos taxonómico y bioestratigráfico. Este macroyacimiento incluye por el momento una sucesión de 91 localidades de micro- y/o macrovertebrados muestreadas, repartidas a lo largo de unos 300 m de serie estratigráfica, abarcando un intervalo de tiempo de más de un millón de años correspondiente al Aragoniense superior. Durante los 28 meses de trabajo de campo desarrollados a lo largo de las campañas 2002-2003, 2004 y 2005, se han recuperado más de 15.000 restos de macrovertebrados fósiles y más de 1.300 dientes de micromamíferos (cantidad que se verá incrementada en el futuro cuando haya finalizado el lavado y triado de los sedimentos acumulados). Se presenta por primera vez una lista exhaustiva del conjunto de localidades y su contextualización estratigráfica, además de una lista faunística actualizada y una propuesta de biozonación local. La gran riqueza fosilífera de la zona y el enorme esfuerzo de muestreo, combinados con los requerimientos de la legislación vigente sobre protección del patrimonio paleontológico, explican el éxito de la intervención paleontológica. En conjunto, la ampliación del vertedero de Can Mata, con el adecuado control paleontológico, proporciona una oportunidad única para investigar la composición faunística de los ecosistemas terrestres del Aragoniense superior en el suroeste de Europa.

Epibiotic bryozoans on deep-water seleractinian corals from the Catalonia slope (western Mediterranean, Spain, France)

The bryozoan fauna growing on deep-water corals (Lophelia, Madrepora) from the upper-slope of Catalonia (Blanes and Banyuls-sur-mer: NW Mediterranean Sea) was studied. Among the 36 species recorded, a new species, Escharella acuta sp. nov., and a new subspecies, Escharina dutertrei protecta ssp. nov., are described; five other species have been rarely reported or were unknown from the Mediterranean Sea (Copidozoum exiguum, Amphiblestrum flemingii, Schizomavella neptuni, Smittina crystallina, Phylactellipora eximia) . This epibiotic bryozoan fauna differs clearly from shallow-water assemblages and comprises a greater proportion of boreo-atlantic species.

Evaluation of markets for irrigation water in the internal river basins of Catalonia, Spain

Irrigated agriculture has come under close scrutiny in Europe recently because of its high share of total water consumption and its apparent inefficiency. Several water policies have been advocated, in particular the use of economic instruments such as water markets. This paper simulates the impact of a policy based upon water markets on agricultural production in the internal river basins of Catalonia (Spain). This zone presents certain particularities that make it very interesting to study: competition between sectors for the resource (agriculture-urban consumption-recreational uses), recent periods of resource insufficiency and conflicts between irrigators as a result of the measures taken by the hydraulic administration in drought situations. The results show that these markets would guarantee an optimal reassignment of the resource in situations of supply restrictions, and although compared to the situation without markets they would not mean higher economic profits for the irrigators, they could prevent conflicts between them. Nevertheless, doubts exist about their acceptance by irrigators

The impact of inbound demand on price levels in tourism municipalities : Empirical evidence from Catalonia

It is usually argued that tourism exerts negative economic impacts in host jurisdictions through the increase in prices linked to increasing demand for basic services and goods from tourists. This paper surveys 149 products in 45 tourism and non-tourism jurisdictions in Catalonia (which represent a total of 18,500 prices) in order to test empirically several hypotheses related to differences in price levels in tourism and non-tourism jurisdictions. The main results show that prices in tourism jurisdictions are not significantly higher than those in non-tourism ones. The analysis suggests that tourists are likely to pay higher prices than natives for some products

Landscape Systems and Human Land-Use Interactions in Mediterranean Highlands and Littoral Plains during the Late Holocene: Integrated Analysis from the InterAmbAr Project (North-Eastern Catalonia).

The main goal of the InterAmbAr reseach project is to analyze the relationships between landscape systems and human land-use strategies on mountains and littoral plains from a long-term perspective. The study adopts a high resolution analysis of small-scale study areas located in the Mediterranean region of north-eastern Catalonia. The study areas are distributed along an altitudinal transect from the high mountain (above 2000m a.s.l.) to the littoral plain of Empordà (Fig. 1). High resolution interdisciplinary research has been carried out from 2010, based on the integration of palaeoenvironmental and archaeological data. The micro-scale approach is used to understand human-environmental relationships. It allows better understanding of the local-regional nature of environmental changes and the synergies between catchment-based systems, hydro-sedimentary regimes, human mobility, land-uses, human environments, demography, etc.
