El nuevo paradigma de aprendizaje y las nuevas tecnologías

El Espacio Europeo de Educacion Superior ha propiciado un nuevo marco, centrado en el estudiante y en su aprendizaje lo largo de la vida, que ofrece nuevas oportunidades formativas. Para ello, resulta necesario que la universidad replantee su modelo educativo, impulsando y estimulando la educacion activa del estudiante, a traves de su planificacion docente e institucional. En el primer apartado de este articulo, se revisan algunos ejemplos de modelos educativos centrados en el estudiante, desde la perspectiva de la institucion, el profesorado y el estudiante. Asimismo, las TIC juegan un importante papel en este cambio de paradigma. En la segunda parte de este articulo se revisa la posible contribucion de estas herramientas como facilitadoras de los procesos de administracion y gestion; como contenido de estudio, que permita a los estudiantes enfrentarse a los nuevos retos de la sociedad, a traves de una adecuada alfabetizacion digital; y, sobre todo, como facilitadoras de nuevos modelos y estrategias de formacion. ABSTRACT The TIC and the New Paradigm of Learning The European Higher Education Area (EHEA) has led to a new educational framework, focusing on the students and their lifelong learning and offering new educational opportunities for all. To achieve this, it is necessary that the university reconsider its educational model, fostering and encouraging an active student education through a deep planning of teaching and institutional organization. In the first section of this article,were view some examples of student-centered education models, taking into account the perspective of the institution, faculty and students. ICT also plays an important role in this paradigm shift. In the second part of this article, were view the potential contribution of these technological tools as facilitators of administration and management processes; we also analyze them as an specific subject of learning that allows students to face the new challenges of society through appropriate digital literacy and, above all, as facilitators of new models and strategies of training.
The absolute positioning of spaceborne INSAR data using the integer ambiguity method

In this paper, the capability of the integer ambiguity method to find the absolute position of InSAR data is demonstrated. A radargrammetric model is used for the space triangulation. The method is demonstrated using ERS data of the Thames region and the results are compared to GPS measurements and a digital elevation model. The GPS stations, not visible in the image, are located on the InSAR data using a simple range‐Doppler algorithm and an analysis of their positions is undertaken. The results are consistent with other methods but with the advantage that the radargrammetric model is very simple. The results also highlight the problems of integrating GPS data with InSAR data in urban areas where a GPS station may not be representative of the dominant scatterers within a resolution cell, and they suggest methods that might be applied in future to reduce this problem. The model should help the integration of InSAR data with other geometric survey data.
Petrology and Geochemistry of the Late Eocene Harrison Pass Pluton, Ruby Mountains Core Complex, Northeastern Nevada

Evaluation of feed resources in mixed crop-livestock systems in Sudano-Sahelian zone of Mali in West Africa

Livestock are important assets to the rural poor in developing countries but are faced with the major challenge of marked seasonal feed availability. A study was carried out to assess existing and potential feed resources and constraints to livestock production in Southern part of Mali. A feed assessment tool was used to collect necessary data. The assessment included focus group discussions and individual interviews. Results showed that seasonal shortage in feed supply, absence of livestock route and lack of watering points were the major constraints facing livestock production in the study areas. Pastures and green forage were the main feed for animal during the wet season while crop residues, fodder trees and shrubs were the main source of feed in the dry season. Results further showed that almost all types of crop residues were used for livestock feeding compared to other uses. The highest dry matter contents of ruminant total diet came from grazing
Chitosan/Polylactic Acid Nanofibers Containing Astragaloside IV as a New Biodegradable Wound Dressing for Wound Healing

The ideal wound dressing should adequately protect the wound from bacterial infection and provide a suitable healing environment for the wound. Thus, we prepared a biodegradable functional nanofiber dressing with good antibacterial and biocompatibility by electrospinning technology. The average diameter of the dressing was 354 ± 185 nm, and the porosity was 93.27%. Scanning electron microscopy (SEM) showed that the dressing was smooth without beading. It was also characterized by Fourier-transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD). The wettability and water vapor permeability of the dressing were tested; the results showed that the dressing had good wettability and permeability. The ability of drug release indicates that continuous release over a period of time is beneficial to wound healing. Finally, the antibacterial effect and in vivo pharmacodynamic evaluation of AS/CS/PLA nanofiber dressing were studied; the result showed that it had significant antibacterial activity and the ability to promote wound healing.
Effect of varying oceanicity on early- to mid-Holocene palaeohydrology, Kola Peninsula, Russia: isotopic evidence from treeline lakes

The stable-isotope stratigraphy of sedimentary organic matter and algal cellulose in cores from two lakes near treeline on the Kola Peninsula indicate changes in water and nutrient balance that correlate with inferred expansion of Pinus sylvestris during the early to mid-Holocene. Trends in cellulose-inferred lakewater δ18O values for both lakes suggest that moist conditions after deglaciation were followed by progressive drying from about 9500 to between 8000 and 7500 14C yr BP. Although pine appeared in the area by 8000 14C yr BP, the maximum density of trees locally, as suggested by stomate evidence, occurred during subsequent moistening between 7500 and 6000 14C yr BP. This is c. 1000 years later than in other regions of northern Russia and is possibly attributable to limitations on seedling establishment and survival due to root desiccation during dry winters. Changes in nutrient balance and productivity in the lakes, as inferred from variations in sediment carbon and nitrogen elemental abundances and their respective stable-isotope signatures, are also consistent with expected changes in hydrological and edaphic conditions. Development of moister conditions at about 7000 14C yr BP on the Kola Peninsula is in harmony with evidence for increased oceanicity at this time in central Siberia, which is thought to reflect enhanced propagation of warm, moist air masses across northern Eurasia due to increased sea-surface temperatures and reduced sea-ice cover in the Nordic Seas.
Natriuretic Peptides and their Role in Clinical Practice in Cardiovascular Disease

Natriuretic peptides (NP) have been the center of particular focus and discussion in the last several years. Their impact in cardiovascular and non cardiovascular medicine is persistently growing as we slowly begin to understand that their value may be beyond what we ever imagined. The discovery and isolation of atrial natriuretic peptide (ANP), a polypeptide hormone, secreted by the heart is credited to de Bold in 1979, although the secretory granules were first recognized in 1956 (1, 2). Natriuretic polypeptides hormones (NP) circulate and are stored in several forms namely ANP, brain natriuretic peptide (BNP), and C-type natriuretic peptide (CNP). More recently, the fourth discovered NP was dendroapsis naturetic peptide, a D-type NP found in the green mamba that remains of unknown significance in humans. There has been extensive research on the role of NPs in cardiovascular disease state, and more specifically BNP and pro-BNP have become the center of attention to guide medical care in patients with congestive heart failure (CHF), coronary artery disease, and valvular heart disease (3). The purpose of this article is to provide an overview of the role of NPs in the pathogenesis of cardiovascular disease. We also discuss the diagnostic and prognostic utilities of NPs and their therapeutic roles in cardiovascular medicine. It is important to recognize that NPs have been linked to many noncardiovascular disease processes and may prove beneficial in their outcome, but the discussions of such studies are beyond the scope of this article.

Vulnerability of two European lakes in response to future climatic changes

Temperate deep freshwater lakes are important resources of drinking water and fishing, and regional key recreation areas. Their deep water often hosts highly specialised fauna surviving since glacial times. Theoretical and observational studies suggest a vulnerability of these hydro‐ecosystems to reduced mixing and ventilation within the ongoing climatic change. Here we use a numerical thermal lake model, verified over the 20th century, to quantify the transient thermal behaviour of two European lakes in response to the observed 20th‐century and predicted 21th‐century climate changes. In contrast to Lac d'Annecy (France) which, after adaptation, maintains its modern mixing behaviour, Ammersee (Germany) is expected to undergo a dramatic and persistent lack of mixing starting from ∼2020, when European air temperatures should be ∼1°C warmer. The resulting lack of oxygenation will irreversibly destroy the deepwater fauna prevailing since 15 kyrs.
Deep structure of the U.S. Atlantic continental margin, offshore South Carolina, from coincident ocean bottom and multichannel seismic data

We present the results of a combined multichannel seismic reflection (MCS) and wide-angle, ocean bottom seismic profile collected in 1988 across the Carolina Trough on the U.S. Atlantic continental margin. Inversion of vertical-incidence and wide-angle travel time data has produced a velocity model of the entire crust across the continent-ocean transition. The margin consists of three structural elements: (1) rifted continental crust, comprising 1–4 km of post-rift sedimentary rocks overlying a 30–34 km thick subsedimentary crust, (2) transitional crust, a 70- to 80-km-wide zone comprising up to 12 km of postrift sedimentary rocks overlying a 10- to 24-km-thick subsedimentary crust, and (3) oceanic crust, comprising 8 km of sedimentary rocks overlying an 8-km-thick crystalline crust. The boundary between rifted continental and transitional crust, marked by the Brunswick magnetic anomaly, represents an abrupt change in physical properties, with strong lateral increases in seismic velocity, density, and magnetic susceptibility. The transitional crust contains mid-crustal seaward-dipping reflections observed on the MCS section and has seismic velocities of 6.5–6.9 km/s in the midcrust and 7.2–7.5 km/s in the lower crust. Modeling of potential field data shows that transitional crust also produces the prominent, margin-parallel gravity anomaly and the Brunswick and East Coast magnetic anomalies. These observations support the interpretation that the transitional crust was formed by magmatism during continental breakup. The prodigious thickness (up to 24 km) of igneous material rivals that interpreted on continental margins of the North Atlantic (e.g., Hatton Bank and Voring Plateau), which formed in the vicinity of the Iceland hotspot. These observations, when combined with other transects across the margin, confirm previous suggestions that the U.S. Atlantic margin is strongly volcanic and further imply that the magmatism was not the result of a long-lived mantle plume.
Environmental Experiences of Malaysian adolescents in two neighbourhoods in Johor Bahru, Malaysia

This research has addressed gaps in knowledge relating to environmental experiences of Malaysian adolescents in two neighbourhoods in Johor Bahru, Malaysia. This thesis discusses how the adolescents' experiences may differ from adults' assumptions and planning. The study begins by highlighting current issues relating to adolescents and urban open space planning and design in Johor Bahru, Malaysia. Survey questionnaires were used as a research tool to reveal adolescents' time use and environmental experiences of their housing area, neighbourhood and the city. The time use not only revealed their activities but also places they liked or valued and their ideal housing neighbourhood environment. Time use data diaries and interviews were used to verify the data from the questionnaire and to seek more specific data of what they wanted from their outdoor environment. The findings of the research elucidate that there were both similarities and differences in Malaysian adolescents' use of their outdoor environment across different ethnic backgrounds, genders and ages. It is concluded that inadequacies existed in current Johor Bahru urban planning in addressing the needs of the adolescents. Furthermore, from this study, the Malaysian adolescents assigned attributes or specific criteria to the facilities and spaces they wanted within their housing area, neighbourhood and the city. The facilities and spaces they wanted were linked to their physical and social activities which they would like to do. The attributes assigned by the Malaysian adolescents are elements of play, variety, ambience, size, safety, fun and excitement, challenge, walkable, aesthetic and green, sociability, accessibility, intelligent and possessing affordances for sports activities. Based on the research findings, this study outlines recommendations for Malaysian housing and neighbourhood landscape in relation to adolescents' needs. Early consideration of adolescents' needs should be incorporated in the planning and design process. One of the recommendations should include providing opportunities for Malaysian adolescents' participation to determine their needs for facilities and spaces in housing area and the city during the planning and design stage.

In the areas adjacent to the drowned Pleistocene continent of Sunda e present-day Mainland and Island SE Asia e the Austronesian Hypothesis of a diaspora of rice cultivators from Taiwan w4200 years ago has often been linked with the start of farming. Mounting evidence suggests that these developments should not be conflated and that alternative explanations should be considered, including indigenous inception of complex patterns of plant food production and early exchange of plants, animals, technology and genes. We review evidence for widespread forest disturbance in the Early Holocene which may accompany the beginnings of complex food-production. Although often insubstantial, evidence for incipient and developing management of rainforest vegetation and of developing complex relationships with plants is present, and early enough to suggest that during the Early to mid-Holocene this vast region was marked by different approaches to plant food production. The trajectory of the increasingly complex relationships between people and their food organisms was strongly locally contingent and in many cases did not result in the development of agricultural systems that were recognisable as such at the time of early European encounters. Diverse resource management economies in the Sunda and neighbouring regions appear to have accompanied rather than replaced a reliance on hunting and gathering. This, together with evidence for Early Holocene interaction between these neighbours, gives cause for us to question some authors continued adherence to a singular narrative of the Austronesian Hypothesis and the ‘Neolithisation’ of this part of the world. It also leads us to suggest that the forests of this vast region are, to an extent, a cultural artefact. 2014 The Authors. Published by Elsevier Ltd. All rights reserved.
Three-dimensional Modelling of Stratified Coastal Waters

Abstract An implicit baroclinic 3-D model developed to simulate the circulation in coastal waters, is presented. The model has hydrodynamic, transport and turbulence model components. It is a composite finite difference–finite element model. In the horizontal plane, second order central finite differences on a staggered scheme and in the vertical Galerkin method with linear shape functions are used. Implicit equations are solved by Crank Nicholson method which has second order accuracy in time also. Developed model predictions are compared with the analytical solutions of steady wind-driven circulatory flow and tidal flow. Model predictions are tested with an experiment performed on the buoyant surface jet discharge. Then, the model is applied to the Goksu Lagoon system located on the Mediterranean coast of Turkey, where there exist some measurements of salinity, temperature and velocity. Model predictions are in good agreement with the field data.
Occupational class and cause specific mortality in middle aged men in 11 European countries: comparison of population based studies. EU Working Group on Socioeconomic Inequalities in Health.

OBJECTIVES To compare countries in western Europe with respect to class differences in mortality from specific causes of death and to assess the contributions these causes make to class differences in total mortality. DESIGN Comparison of cause of death in manual and non-manual classes, using data on mortality from national studies. SETTING Eleven western European countries in the period 1980-9. SUBJECTS Men aged 45-59 years at death. RESULTS A north-south gradient was observed: mortality from ischaemic heart disease was strongly related to occupational class in England and Wales, Ireland, Finland, Sweden, Norway, and Denmark, but not in France, Switzerland, and Mediterranean countries. In the latter countries, cancers other than lung cancer and gastrointestinal diseases made a large contribution to class differences in total mortality. Inequalities in lung cancer, cerebrovascular disease, and external causes of death also varied greatly between countries. CONCLUSIONS These variations in cause specific mortality indicate large differences between countries in the contribution that disease specific risk factors like smoking and alcohol consumption make to socioeconomic inequalities in mortality. The mortality advantage of people in higher occupational classes is independent of the precise diseases and risk factors involved.

The objective of this study is to investigate the impact of price, value, satisfaction, quality, and performance on the loyalty of ecotourists toward the destination. By using an attitudinal approach, the study conceptualizes loyalty by analyzing the post-purchase decision-making of the ecotourists (i.e., their intent to return to, or recommend, the destination). The analysis is based on 454 on-site surveys collected from ecotourists visiting the Galapagos Islands in Ecuador. The results from the path analysis indicate that ecotourists are unlikely to return but are willing to recommend the destination. The findings suggest that the Galapagos Islands may be perceived as an iconic destination and considered a “once in a lifetime experience”. The loyalty of ecotourists to the Galapagos is reflected only by their willingness to recommend the destination. The article concludes with recommendations for tourism and government organizations regarding the management of word of mouth (WOM) communications and first time visitors in an attempt to improve sustainability.
Polarization studies of atmospheric objects in the low troposphere by lidar

In the present work some results of polarization measurements in the planetary boundary layer are reported. The observations described were performed by a ground-based lidar over the region of the Sofia city (where various industrial enterprises exist along with a heavy transport and aerial communications). The data obtained when sounding in different meteorological situations (`clear' atmosphere, rain, fog, snowfall) are considered. Certain differences are established in the depolarization properties of `clear' atmosphere in dependence of the meteorological condition. The developments of fog and snowfall are traced; the effects of the underlying surface are sought when sounding in fog; various types of situations during a snowfall are pointed as well. An attempt is made to follow the development of the processes which proceed during an interaction between air masses with different properties (e.g. a front advection); as a result the formation of the cloud system over the region is traced. Definite differences between the microphysical properties of the aerosol near the clouds (Fmb, Ns) base and top are established as well.
