[ES] Los graves problemas territoriales existentes en Canarias han motivado un continuo desarrollo normativo autonómico desde los ochenta que culminó con la aprobación en 2000 de un Texto Refundido de las leyes de ordenación del territorio en el que se intentó estructurar jerárquicamente la ordenación territorial, el planeamiento urbanístico y la protección de los espacios naturales. Además de dotarse con instrumentos propios de ordenación, la presente década se ha caracterizado por la definición normativa de un modelo de desarrollo sostenible a través de la formulación de unas Directrices de ordenación. En este artículo abordamos el análisis de las características de la ordenación territorial en Canarias y del modelo de desarrollo promulgado, con el fin de manifestar su escasa capacidad de intervención al mismo tiempo que aportamos una reflexión sobre las nuevas orientaciones anti-cíclicas aprobadas recientemente y que pueden suponer el desmoronamiento de parte del modelo de desarrollo construido en la presente década.

[ES] En Canarias, en las últimas dos décadas se ha generalizado en la actividad de ordenación territorial el empleo de las denominadas unidades de diagnóstico, que fueron reguladas en 1995 por el Decreto 35/95 de Evaluación Ambiental (hoy derogado). Las unidades ambientales homogéneas se han convertido en una herramienta del planificador. La validez de las mismas, los problemas y ventajas que ofrecen en la práctica, es analizada en este artículo de cara a la ordenación y gestión litorales. Desde la praxis se valora la eficacia de esta metodología en las costas orientales de Canarias y su posible extrapolación a otros territorios continentales, comprobando su validez y eficacia en las cercanas costas saharianas y su espacio litoral.

[ES]Esta comunicación presenta los resultados obtenidos de la aplicación de dos proyectos de innovación docente (PID) en la asignatura de geografía humana de Planificación y Gestión Territorial de Destinos Turísticos, que se imparte en tercer curso del grado de turismo de La Universidad de La Laguna. El objetivo de los proyectos es que los alumnos adquirieran un aprendizaje práctico continuado de la asignatura a través del uso turístico de los geomorfositios volcánicos de Tenerife y de la promoción turística oficial en youtube.

Landslide hazard and risk are growing as a consequence of climate change and demographic pressure. Land‐use planning represents a powerful tool to manage this socio‐economic problem and build sustainable and landslide resilient communities. Landslide inventory maps are a cornerstone of land‐use planning and, consequently, their quality assessment represents a burning issue. This work aimed to define the quality parameters of a landslide inventory and assess its spatial and temporal accuracy with regard to its possible applications to land‐use planning. In this sense, I proceeded according to a two‐steps approach. An overall assessment of the accuracy of data geographic positioning was performed on four case study sites located in the Italian Northern Apennines. The quantification of the overall spatial and temporal accuracy, instead, focused on the Dorgola Valley (Province of Reggio Emilia). The assessment of spatial accuracy involved a comparison between remotely sensed and field survey data, as well as an innovative fuzzylike analysis of a multi‐temporal landslide inventory map. Conversely, long‐ and short‐term landslide temporal persistence was appraised over a period of 60 years with the aid of 18 remotely sensed image sets. These results were eventually compared with the current Territorial Plan for Provincial Coordination (PTCP) of the Province of Reggio Emilia. The outcome of this work suggested that geomorphologically detected and mapped landslides are a significant approximation of a more complex reality. In order to convey to the end‐users this intrinsic uncertainty, a new form of cartographic representation is needed. In this sense, a fuzzy raster landslide map may be an option. With regard to land‐use planning, landslide inventory maps, if appropriately updated, confirmed to be essential decision‐support tools. This research, however, proved that their spatial and temporal uncertainty discourages any direct use as zoning maps, especially when zoning itself is associated to statutory or advisory regulations.

In Arabidopsis (Arabidopsis thaliana), the blue light photoreceptor phototropins (phot1 and phot2) fine-tune the photosynthetic status of the plant by controlling several important adaptive processes in response to environmental light variations. These processes include stem and petiole phototropism (leaf positioning), leaf flattening, stomatal opening, and chloroplast movements. The PHYTOCHROME KINASE SUBSTRATE (PKS) protein family comprises four members in Arabidopsis (PKS1-PKS4). PKS1 is a novel phot1 signaling element during phototropism, as it interacts with phot1 and the important signaling element NONPHOTOTROPIC HYPOCOTYL3 (NPH3) and is required for normal phot1-mediated phototropism. In this study, we have analyzed more globally the role of three PKS members (PKS1, PKS2, and PKS4). Systematic analysis of mutants reveals that PKS2 (and to a lesser extent PKS1) act in the same subset of phototropin-controlled responses as NPH3, namely leaf flattening and positioning. PKS1, PKS2, and NPH3 coimmunoprecipitate with both phot1-green fluorescent protein and phot2-green fluorescent protein in leaf extracts. Genetic experiments position PKS2 within phot1 and phot2 pathways controlling leaf positioning and leaf flattening, respectively. NPH3 can act in both phot1 and phot2 pathways, and synergistic interactions observed between pks2 and nph3 mutants suggest complementary roles of PKS2 and NPH3 during phototropin signaling. Finally, several observations further suggest that PKS2 may regulate leaf flattening and positioning by controlling auxin homeostasis. Together with previous findings, our results indicate that the PKS proteins represent an important family of phototropin signaling proteins.

Although surgical navigation reduces the rate of malpositioned acetabular cups in total hip arthroplasty (THA), its use has not been widely adopted. As a result of our perceived need for simple and efficient methods of navigation, we developed a mechanical navigation device for acetabular cup orientation.
