Spatial and temporal variability of diatom and macroinvertebrate communities: How representative are ecological classifications within a river system?
2012
Evaluation of river condition is complicated by dynamic relationships between river assemblages and their environment. We assessed variation of ecological status classifications of stream diatom and macroinvertebrate communities within a boreal river system. We specifically examined whether results of ecological classifications are concordant across taxonomic groups and among main channel and headwater side tributaries of this river system. We further assessed whether ecological classifications are stable from year to year and whether classifications show predictable relationships to major stressor gradients. The estimated ecological condition varied considerably among and between reaches o…
Geometric and morphologic evolution of normal fault planes and traces from 2D to 4D data
2003
Abstract The detailed 3D geometry of normal fault planes is described and analysed using datasets from outcrop studies (2D), seismic surveys (3D) and analogue models (4D). Different geometric configurations of simple isolated normal faults are studied by reference to processes of normal fault propagation. When a normal fault propagates without interacting with other fault zones, the entire border of the principal plane displays characteristic connected secondary structures. These secondary structures cause bifurcations of the principal fault terminations. The along-strike terminations of the principal plane display typical bifurcation configurations (‘ear geometry‘). The orientation of the …
Response of macrophyte communities and status metrics to natural gradients and land use in boreal lakes
2012
Abstract We studied the relations of aquatic macrophyte communities, ecological quality metrics and water quality to lake characteristics and to land use defined at multiple spatial scales (three lake marginal zones (LMZs) of contrasting width and the whole topographic catchment) in 110 boreal lakes in Finland using ordination and generalised additive modelling. Variation in macrophyte community composition of our lakes was related to water quality, land use, latitude and lake morphology. Relationships of macrophyte status metrics – the proportion of type-specific species (TT50), Percent Model Affinity (PMA) and Trophic Index (TI) – to land use were scale dependent. The proportion of agricu…
Evaluation of cliff recession in the Valle dei Templi in Agrigento (Sicily)
2015
Abstract The sacral complex of the Valle dei Templi in Agrigento, added in the UNESCO Heritage Site List, stands over the crest of a rigid calcarenite cuesta, which overlies a layer of partially saturated (S = 6–12%) carbonate sand. In turn, the sand stratum lies on a thick stratum of clays. The environment is highly prone to landslides as highlighted by several previous studies that identify the undermining of slopes and the discontinuity pattern, occurred in the late Neotectonic phase, as causes of cliff failure. For wider and less exposed areas, where the undermining local instabilities can be present because of the specific morphology of the site, a recent research has proposed a new in…
Methodologies for feasibility studies related to wastewater reclamation and reuse projects
2006
Abstract About 20% of the total surface water in Europe is strongly threatened due to pollution problems, and 60% of European cities over-exploit their groundwater resources. The European Framework Water Directive established that by the year 2015 “a good ecological state” of all European water resources and a sustainable use of water must be achieved. Wastewater reuse presents a promising solution to the growing pressure on Europe's water resources. However, wastewater reuse implementation in Europe faces obstacles that include insufficient public acceptance; technical, economic and hygienic risks; and lack of regulations. On the other hand, a very important aspect to implement a water reu…
Directionlets: Anisotropic Multidirectional representation with separable filtering
2006
In spite of the success of the standard wavelet transform (WT) in image processing in recent years, the efficiency of its representation is limited by the spatial isotropy of its basis functions built in the horizontal and vertical directions. One-dimensional (1-D) discontinuities in images (edges and contours) that are very important elements in visual perception, intersect too many wavelet basis functions and lead to a nonsparse representation. To efficiently capture these anisotropic geometrical structures characterized by many more than the horizontal and vertical directions, a more complex multidirectional (M-DIR) and anisotropic transform is required. We present a new lattice-based pe…
Aplicación del Balanced Scorecard para la gestión estratégica del proyecto educativo del Conservatorio Profesional de Danza José Espadero
2017
Esta investigación apoyada en el método de estudio de casos se ha llevado a cabo en un centro educativo público durante los años 2012-2015, concretamente en el Conservatorio de Música y Danza José Espadero. Consiste en utilizar el modelo del Balanced Scorecard (BSC, en lo sucesivo) para el diseño y la gestión del proyecto educativo del centro desde un enfoque estratégico, donde la estrategia para hacer llegar la propuesta de valor a los grupos de interés (alumnos, familias, personal del centro, Administración educativa y sociedad en general) es el centro del control de gestión por parte del equipo directivo. Se ha explotado las posibilidades que ofrecen las tecnologías de la información y l…
Integración de la gestión de la calidad y la supply chain. Análisis del proceso desde un enfoque cualitativo de investigación
2019
El desarrollo de la competitividad en las empresas es determinante para el crecimiento de las organizaciones y el país. La gestión de la calidad (QM) brinda a las empresas las capacidades para el desarrollo de productos y servicios que cumplan con estándares de calidad que son reconocidos por los mercados locales y globales. De otra parte, la gestión de la supply chain management (SCM) permite a las empresas el desarrollo de la competitividad a través de la estructura de cadenas de valor, integrando a los clientes y a los proveedores para entregar los bienes y servicios en las condiciones de tiempo, cantidad y lugar pactados. Tanto la QM como la SCM, presentan condiciones e intereses que so…

Evaluación de las democracias contemporáneas bajo los efectos de la crisis económica
2017
RESUMEN: Historicamente ha habido un debate sobre el resultado del proceso democratico que se centra en si el producto de las democracias deben ser derechos politicos y libertades civiles o por el contrario deben ser bienes y servicios basicos a los ciudadanos. La crisis economica global que comenzo en 2007 ha tenido un impacto en las politicas economicas de los gobiernos que han tenido que aplicar medidas de ajuste, a veces impuestas por organismos internacionales no sujetos a control ciudadanos de los paises donde se aplicaban dichas medidas, generando protestas y revueltas y la aparicion de nuevos partidos politicos. En este escenario la crisis economica proporciona una oportunidad unica…
