El arte como recurso educativo en la adquisición del pensamiento matemático

La presente propuesta didáctica profundiza en las posibilidades del arte como recurso para mejorar el pensamiento matemático durante las primeras etapas de la educación escolar. De este modo, se define como objetivo general el siguiente: diseñar una propuesta de intervención para la mejora de la adquisición del pensamiento matemático y las habilidades lógico-matemáticas a través del arte como recurso educativo en el segundo ciclo de Educación Infantil, en un Centro Público de Educación Infantil y Primaria en Valladolid. Concretamente, se opta por incluir las formas geométricas del círculo y el triángulo a través del análisis de varios cuadros. Las dinámicas de las sesiones que conforman esta propuesta didáctica se basan en las fases de adquisición de conocimientos geométricos propuestas en el modelo de Van Hiele.Grado en Educación Infanti

Effects of Alzheimer’s Disease on Visual Target Detection: A “Peripheral Bias”

Visual exploration is an omnipresent activity in everyday life, and might represent an important determinant of visual attention deficits in patients with Alzheimer’s Disease (AD). The present study aimed at investigating visual search performance in AD patients, in particular target detection in the far periphery, in daily living scenes. Eighteen AD patients and 20 healthy controls participated in the study. They were asked to freely explore a hemispherical screen, covering ±90°, and to respond to targets presented at 10°, 30°, and 50° eccentricity, while their eye movements were recorded. Compared to healthy controls, AD patients recognized less targets appearing in the center. No difference was found in target detection in the periphery. This pattern was confirmed by the fixation distribution analysis. These results show a neglect for the central part of the visual field for AD patients and provide new insights by mean of a search task involving a larger field of view

Isquemia aguda de miembros inferiores secundaria a ergortismo

Paciente de género femenino, de 21 años de edad, quien ingresó por dolor progresivo e intenso en miembros inferiores, y refirió antecedente reciente de ingestión de derivados del ergot. Al examen físico se observó ausencia de pulsos en ambos miembros inferiores. Por angiotomografia se documentó disminución severa, generalizada y bilateral, del calibre de los vasos arteriales de miembros inferiores. Se diagnosticó isquemia arterial aguda secundaria a ergotismo y se inició tratamiento con vasodilatadores y calcio-antagonistas, que resolvió los síntomas en su totalidad.21 years old female patient admitted for progressive and intense pain in lower limbs, that narrated a recent history of ergot ingestion. On physical examination there was absence of pulses in both lower limbs. Severe, generalized and bilateral decrease of caliber of arterial vessels of the lower limbs was documented by angiotomography. Acute arterial ischemia of lower limbs secondary to ergotism was diagnosed and treatment with vasodilators and calcium antagonists was initiated, resolving entirely the symptoms

The District Energy-Efficient Retrofitting of Torrelago (Laguna de Duero – Spain)

The urban growth is estimated to reach up the 66 % by 2050 and consequently the need of resources within the cities will increase significantly. This, combined with the 40 % of energy consumption and 36 % of CO2 emissions of the building sector, makes necessary to accelerate the transition towards more sustainable cities. The CITyFiED project contributes to this transition, aiming to develop an innovative and holistic methodological approach for energy-efficient district renovation and deliver three large scale demonstration cases in the cities of Lund (Sweden), Laguna de Duero (Spain) and Soma (Turkey). CITyFiED methodology consists of several phases that ease the decision-making tasks towards the district renovation, considering the energy efficiency as the main pillar and local authorities as clients. For the case of Torrelago district (Spain) the intervention consists of a set of energy conservative measures including the facąde retrofitting of 143.025 m2 of living space in 31 twelve-storey buildings; the renovation of the district heating network with a new biomass thermal plant; the integration of renewable energy sources, including a micro-cogeneration system, and the installation of individual smart meters. After the renovation action, one-year monitoring campaign is ongoing. The CITyFiED monitoring platform will collect information from the energy systems and deliver environmental, technical, economic and social key performance indicators by March 2019. At the end of the project the achievement of the predefined goals will be verified: Up to 36 % of energy saving and 3,429 tons-CO2/yr emissions saving covering the 59,4 % of the energy consumption with renewable sources.The research and results presented in this paper evolve from activities related to the CITyFiED project, which has received funding from the European Commission under the Grant Agreement no. 609129. This article is the result of cooperative research work of many experts from various countries and we would like to gratefully acknowledge the rest of the CITyFiED partners

A "Risk Based Thinking" approach for tourism in Alaska

Tourism sector in Alaska and elsewhere needs to incorporate into everyday business operations a risk based thinking approach which becomes a tool to proactively manage risk and opportunities. Therefore this research has been focused in putting together a basic guide how tourism operators in general, specially from Alaska, could implement an integral risk management approach for an specific tour adventure, example that could be replicated to other type of risks found in Alaska tourism. Risk management is an invaluable tool for the tourism industry and the communities it supports as it provides the means by which risk can be identified and treated, preventing or minimizing the effects of crises and disasters upon this vital industry for the state of Alaska.Abstract / Table of Contents / List of Figures / List of Tables / Chapter 1 Introduction / Chapter 2 Literature Review / Chapter 3 Methodology / Chapter 4 Alaska Tourism Risk Management Guide / Chapter 5 Communication of Risks / Chapter 6 Monitor and Review Risks / Chapter 7 Conclusion and Recommendations / Reference
