Consistent phenological shifts in the making of a biodiversity hotspot: the Cape flora
2011
Abstract Background The best documented survival responses of organisms to past climate change on short (glacial-interglacial) timescales are distributional shifts. Despite ample evidence on such timescales for local adaptations of populations at specific sites, the long-term impacts of such changes on evolutionary significant units in response to past climatic change have been little documented. Here we use phylogenies to reconstruct changes in distribution and flowering ecology of the Cape flora - South Africa's biodiversity hotspot - through a period of past (Neogene and Quaternary) changes in the seasonality of rainfall over a timescale of several million years. Results Forty-three dist…
RISCALDAMENTO GLOBALE E CITTÀ L’incremento della vegetazione e la progettazione urbana, tra non finito e paesaggio urbano
2023
Il contributo mette a fuoco l’interazione fra la progettazione urbana e le strategie per il contenimento del riscaldamento globale costruendo un ragionamento che partendo dall’eredità del Movimento Moderno, include gli esiti delle ricerche più recenti. Da tale base di partenza scientifica emerge come protagonista la tesi fondata sull’aumento della vegetazione in ambito urbano, come strumento indispensabile alla mitigazione delle temperature. Tale proposta trova, nel corso dell’approfondimento, una verifica sperimentale attraverso alcune concrete esperienze di progettazione che coniugano l’obiettivo ambientale avendo cura, al contempo, della qualità degli spazi dell’abitare. I progetti dimos…
Measuring the Economic, Environmental, and Social Sustainability of Short Food Supply Chains
2019
The production and distribution of food are among the hot topics debated in the context of sustainable development. Short food supply chains (SFSCs) are now widely believed to be more sustainable in comparison to mass food delivery systems. To date, very little quantitative evidence exists on the impacts of various types of food supply chains. Using a cross-sectional quantitative approach, this study assesses the sustainability of distribution channels in short and long food supply chains based on 208 food producers across seven countries: France, Hungary, Italy, Norway, Poland, the United Kingdom, and Vietnam. Ten distribution channel types are used in this study. To provide a comprehensiv…
Las técnicas de relajación y meditación, su aplicación en el aula y sus beneficios en el alumnado de educación primaria
2021
Las técnicas de relajación y meditación están siendo introducidas en el aula por los beneficios que se van constatando a través de diferentes estudios científicos y en la práctica docente. Cada vez son más los estudios que se dirigen a comprobar cómo estas prácticas influyen en diferentes variables que mejoran el aprendizaje del alumnado y la práctica docente. La tesis presentada analiza, con población de dos centros educativos de la Comunidad Valenciana (CEIP La Lloma del Mas de Bétera y el CEIP Martínez Torres de Aldaia) diferentes variables que pueden mejorar con la aplicación de las técnicas de relajación y meditación en el aula. Las variables que se estudian son el clima de aula, el ni…
Asociación entre clima motivacional, ajuste escolar y funcionalidad familiar en adolescentes
2019
The present study seeks to define and contrast an explanatory model of motivational climate, school adjustment and family functioning, and to analyse the existing associations between the aforementioned variables through structural equation analysis. The sample includes 2,134 adolescents aged 12 to 18 years from the province of Granada. Motivational climate (PMCSQ-2), school adjustment (EBAE-10) and family functioning (APGAR) are analysed. A descriptive cross-sectional design is used and the program AMOS 23.0 is employed to construct the multi-group structural equation model. The model showed appropriate fit (χ2 = 241.34; df = 17; p < .001; CFI = .953; NFI = .950; IFI = .953; RMSEA = .079).…
Un enfoque de educación física y salud a la luz de la perspectiva de metas: los contextos de clase y la motivación del alumnado
1995
El propósito de este capítulo es presentar los aspectos principales de la teoría de las metas de logro y su utilidad para comprender la motivación del alumnado al realizar actividad física. Nos centraremos en un enfoque de educación física y salud y analizaremos cómo un tipo de metas está relacionado con unas estructuras concretas que surgen en la clase de educación física (tareas o actividades de aprendizaje, la autonomía y responsabilidad del alumnado y la evaluación). Asimismo, comentaremos el papel del profesorado para conseguir crear un ambiente que induzca a unas metas deseables, facilitadoras de experiencias educativas recompensantes, satisfactorias y emancipadoras. Todo ello lo ilus…
La mejora de la convivencia en el aula, en el área de la Educación Física de la educación secundaria obligatoria, mediante la aplicación de un progra…
2017
La Educacion Fisica es una materia integrada como cualquier otra en el sistema educativo, por lo que comparte los mismos problemas comunes al resto de materias, y hace frente a los que le son propios. Uno de estos temas es la convivencia en el aula, el clima de trabajo y la gestion para optimizar su ensenanza. Esta materia, dadas sus caracteristicas y contenidos, provoca una serie de situaciones, relaciones y vivencias muy adecuadas para desarrollar valores, actitudes y normas. Cuando estos se convierten en objetivos educativos, permiten mejorar la convivencia en el aula y aportar un desarrollo social y moral en sus alumnos. Esta investigacion pretende comprobar el alcance de un programa de…
The Relationship between Motivational Climate and Personal Treatment Satisfaction among Young Soccer Players in Norway: The Moderating Role of Suppor…
2020
Motivational climate and coach-behaviour seem important to understand sport involvement and participation. However, less is known about the potential interaction between these facets, and how it relates to athlete satisfaction. This study&rsquo
Here and now: perceptions of Indian Ocean islanders on the climate change and migration nexus
2017
Empirical studies exploring the links between climate change and migration are increasing. Often, perceptions are not fully explored from the people most affected by the climate change and migration nexus. This article contributes to filling this gap by eliciting and analyzing perceptions regarding climate change and migration from an understudied population labelled as being amongst those most immediately and directly affected by climate change: Indian Ocean islanders. Open-ended, semi-structured interviews were conducted in two case study communities in Maldives (Kaafu Guraidhoo with 17 interviews and Raa Dhuvafaaru with 18 interviews) and two case study communities in Lakshadweep, India …
Effects of air pollution on dementia over Europe for present and future climate change scenarios.
2020
The scientific literature is scarce when referring to the influence of atmospheric pollutants on neurodegenerative diseases for present and future climate change scenarios. In this sense, this contribution evaluates the incidence of dementia (Alzheimer's disease, AD, and dementia from unspecified cause, DU) occurring in Europe associated with the exposure to air pollution (essentially NO2 and PM2.5) for the present climatic period (1991-2010) and for a future climate change scenario (RCP8.5, 2031-2050). The GEMM methodology has been applied to air pollution simulations using the chemistry/climate regional model WRF-Chem. Present population data were obtained from NASA's Center for Socioecon…
