El paisaje como valor añadido a la actividad náutica de avistamiento de fauna marina
La actividad náutica de avistamiento de fauna marina en Tenerife se realiza durante todo el año y
cuenta con un atractivo que marca la diferencia con respecto a otros lugares del mundo gracias al
paisaje volcánico y a la situación geográfica. Si bien el principal incentivo es la propia observación
de ballenas y delfines, este trabajo tiene el objetivo de argumentar que el paisaje del litoral del
Tenerife genera un valor añadido a la actividad náutica de avistamiento de cetáceos. Para realizar
tal argumentación se han revisado algunos conceptos clave relativos a la actividad náutica de
avistamiento y se han analizado los impactos económicos y las características geográficas que
favorecen el avistamiento de cetáceos a nivel mundial, nacional y en Canarias. Además, se
presenta esta actividad en Tenerife y se analiza el paisaje en una de las rutas de avistamiento más
practicada en esta isla. Esto, unido al desarrollo de una pequeña base de datos de folletos y
publicidad turística de esta actividad náutica, permitió poner de manifiesto el valor añadido que
puede tener el paisaje en las rutas de avistamiento de fauna marina.The nautical activity of whale watching in Tenerife, is carried out during all the year and has an
attraction that makes the difference relating to other places in the world thanks to the volcanic
landscape and the geographical situation. Even though the main encouragement is the whales and
dolphins sighting, it seeks to argue that the landscape of Tenerife´s coast generates added value
to the nautical activity of whale watching, going unnoticed in the tourist offer. To build this argument,
the key concepts of this work will be collected in the theoretical framework, to study the economic
impacts and the characteristics that profit the sighting of cetaceans at a geographical level
worldwide, nationally and in the Canary Islands. Furthermore, an analysis about the most practiced
whale watching trip is done. All this, together with a small data base development of flyers and
touristic advertising related to this nautical activity, allowed to show up the value that landscape
may add within marine fauna sighting trip
Linking biogeochemical variability and microbial community structure in forest soils: Abies pinsapo-fir forests as a study case
Tradicionalmente, los estudios biogeoquímicos consideraban el suelo como una "caja negra", conectada con el resto del ecosistema mediante flujos de entrada y de salida de nutrientes, en la que éstos experimentan transformaciones mediadas en gran parte por microorganismos desconocidos. El desarrollo de nuevas técnicas moleculares ha incrementado el conocimiento sobre las comunidades microbianas del suelo. Estudios recientes han puesto de manifiesto correspondencias entre la variabilidad de la disponibilidad de nutrientes y la estructura de la comunidad microbiana en suelos forestales. A este respecto, hemos empleado bosques de Abies pinsapo como modelo ya que muestran una gran variabilidad biogeoquímica asociada a diferencias litológicas y sucesionales, mientras que la estacionalidad mediterránea provoca una alta variabilidad intra anual en la disponibilidad de nutrientes. Además, existen pinsapares sujetos a limitación o a saturación de nitrógeno. Mediante análisis del polimorfismo de longitud de fragmentos de restricción terminal (T-RFLP), hemos puesto de manifiesto que los patrones de variabilidad biogeoquímica descritos en los pinsapares se corresponden con cambios en la composición y estructura de sus comunidades bacterianas.Traditionally, soil has been considered as a "black box", connected to the rest of the ecosystem by input and output fluxes, where nutrients are transformed mainly through processes controlled by unknown microorganisms. The development of new molecular techniques has increased our knowledge about microbiological soil communities. Recent studies reveal that change in nutrient availability in forest soils is associated with shifts in the soil community structure. We have used Abies pinsapo fir forests as a model case to this regard, since they show a marked among-sites biogeochemical variability due to changes in lithology and successional status, while Mediterranean seasonality determines high intra-year variability in nutrients availability. Moreover, A. pinsapo forests that are either N-limited or N-saturated do exist. Using terminal restriction fragments length polymorphism (T-RFLP) analysis we have demonstrated that these patterns of biogeochemical variability are associated with shifts in the structure of the soil bacterial communities
A clinical staging model for bipolar disorder : longitudinal approach.
Bipolar disorder (BD) has been identified as a life-course illness with different clinical manifestations from an at-risk to a late stage, supporting the assumption that it would benefit from a staging model. In a previous study, we used a clustering approach to stratify 224 patients with a diagnosis of BD into five clusters based on clinical characteristics, functioning, cognition, general health, and health-related quality of life. This study was design to test the construct validity of our previously developed k-means clustering model and to confirm its longitudinal validity over a span of 3 years. Of the 224 patients included at baseline who were used to develop our model, 129 (57.6%) reached the 3-year follow-up. All life domains except mental health-related quality of life (QoL) showed significant worsening in stages (p < 0.001), suggesting construct validity. Furthermore, as patients progressed through stages, functional decline (p < 0.001) and more complex treatment patterns (p = 0.002) were observed. As expected, at 3 years, the majority of patients remained at the same stage (49.6%), or progressed (20.9%) or regressed (23.3%) one stage. Furthermore, 85% of patients who stayed euthymic during that period remained at the same stage or regressed to previous stages, supporting its longitudinal validity. For that reason, this study provides evidence of the construct and longitudinal validity of an empirically developed, comprehensive staging model for patients with BD. Thus, it may help clinicians and researchers to better understand the disorder and, at the same time, to design more accurate and personalized treatment plans

Predicting Vertical Jump Height from Bar Velocity
The objective of the study was to assess the use of maximum (Vmax) and final propulsive phase (FPV) bar velocity to predict jump height in the weighted jump squat. FPV was defined as the velocity reached just before bar acceleration was lower than gravity (-9.81 m·s-2). Vertical jump height was calculated from the take-off velocity (Vtake-off) provided by a force platform. Thirty swimmers belonging to the National Slovenian swimming team performed a jump squat incremental loading test, lifting 25%, 50%, 75% and 100% of body weight in a Smith machine. Jump performance was simultaneously monitored using an AMTI portable force platform and a linear velocity transducer attached to the barbell. Simple linear regression was used to estimate jump height from the Vmax and FPV recorded by the linear velocity transducer. Vmax (y = 16.577x - 16.384) was able to explain 93% of jump height variance with a standard error of the estimate of 1.47 cm. FPV (y = 12.828x - 6.504) was able to explain 91% of jump height variance with a standard error of the estimate of 1.66 cm. Despite that both variables resulted to be good predictors, heteroscedasticity in the differences between FPV and Vtake-off was observed (r2 = 0.307), while the differences between Vmax and Vtake-off were homogenously distributed (r2 = 0.071). These results suggest that Vmax is a valid tool for estimating vertical jump height in a loaded jump squat test performed in a Smith machine.This study was supported by grants awarded by the Spanish Ministry of Science and Innovation (DEP2012-35774) and Ministry of Education, Culture and Sport (Predoctoral Grant FPU12/00360)

Five-year atmospheric corrosion of cu, cr and ni weathering steels in a wide range of environments
This work considers fourteen weathering steels manufactured by adding Cu, Cr and Ni alloying elements to extra mild steel. The steels were exposed for up to 5 years in different atmospheres. The atmospheric corrosion resistance of the steels was evaluated and the rust layers formed were characterised by X-ray diffraction, optical microscopy and scanning electron microscopy. The addition of Ni, particularly at 3.0 wt%, leads to a notable increase in corrosion resistance. The rusts formed contain lepidocrocite, goethite and spinel phases. X-ray diffraction also detected small amounts of kornelite (industrial atmosphere) and akaganeite (marine atmosphere)
Enfoques de aprendizaje, autorregulación y rendimiento en tres universidades europeas
El trabajo analiza la relación entre enfoques de aprendizaje, autorregulación y rendimiento en estudiantes
universitarios de tres universidades públicas europeas: una británica (UWIC, Cardiff, UK) y
dos españolas (Almería y Granada). Se utilizan dos medidas de autoinforme para la recogida de información,
el cuestionario R-SPQ-2F y las escalas EIPEA. Los resultados indican relaciones de los enfoques
con la autorregulación y el rendimiento académico. Según el tipo de rendimiento analizado (conceptual,
procedimental, actitudinal) se producen relaciones diferentes con los enfoques, lo que puede
dar explicación a las conclusiones dispares encontradas en otras investigaciones. A partir de las conclusiones
se proponen nuevas líneas de investigación
Teaching and evaluation methods preferred by university students
Student preferences and expectations regarding university instruction are increasingly considered as quality indicators
in higher education. In this study we investigate university students¿ expectations and preferences concerning the
teaching process, and we perform a differential study based on variables pertaining to the individual student (gender and
age) and to the teacher (gender). 249 students from the Faculty of Education at the University of Granada participated in
this study. Expectations and preferences are measured using the USET questionnaire (Sander, Stevenson, King & Coates,
2000). Results show that students wish to play a more active role in their learning. The formal lecture is the method most
expected, and at the same time, the one most rejected, by more than half the sample. Variables analysed show significant
differences in several teaching and evaluation methods.
