Intention of coastal communities to support climate change mitigation policies for fish and marine ecosystem preservation
2021
Purpose This paper aims to assess the willingness of individuals living in coastal communities affected by climate change to financially support mitigation policies towards the preservation of marine ecosystems and fish resources and to identify the key drivers of their behaviour. Design/methodology/approach A survey was carried out involving 994 people living in three main Italian coastal communities. To investigate the main factors affecting Italian coastal communities’ willingness to pay (WTP) to support climate change mitigation measures to protect the marine ecosystem and fishery resources, a Tobit regression model was implemented. Findings The results show that these communities are …
The scarcity of worker cooperatives in the USA: enquiring into possible causes
2018
Even though the access of workers to capital has been promoted in some countries for over centuries, Governments and public bodies have started to promote it worldwide, as in previous occasions, more particularly as an aftermath of the Great Recession, usually in the form of worker cooperatives.However, workers’ access to capital in the USA in the form of worker cooperatives is still surprisingly rare. We cannot find any recent public policies at a federal level in order to promote them and the old ones that exist remain mostly obsolete and unknown. Only at a state and local level, we find in the latest years a series of actions directed to achieve this goal, as in the case of New York City…
The role of «perceived loss» aversion on credit screening: an experiment
2013
A major characteristic of credit markets is information asymmetry.To combat its problems, as credit rationing, principals can use a menu of contracts to screen clients with different risk level. We conduct a laboratory experiment to address an important question for such settings —does the framing of the offered menu of contracts interfere with the self-selection mechanism? The answer is yes. We find subjects' choices shift when the same (positive) outcomes of the same menu of contracts are presented in two different frames. Subjects exhibit loss aversion in their perception of the positive outcomes below the reference point, and self-selection fails to occur. Uno de los mayores problemas a…
Quality pricing-to-market
2014
We examine firm's pricing-to-market decisions in vertically differentiated industries featuring a large number of firms that compete monopolistically in the quality space. Firms sell goods of heterogeneous quality to consumers with non-homothetic preferences that differ in their income and thus their marginal willingness to pay for quality increments. We derive closed-form solutions for the pricing game under costly international trade, thus establishing existence and uniqueness. We then examine how the interaction of good quality and market demand for quality affects firms' pricing-to-market decisions. The relative price of high quality goods compared to that of low quality goods is an inc…
Heterogeneidad en el impacto de la política de becas en la escolaridad secundaria postobligatoria en España: un análisis por subgrupos poblacionales
2013
El presente trabajo analiza el impacto de las becas sobre la probabilidad de finalizar con éxito el nivel secundario postobligatorio en España en el caso de diferentes subgrupos poblacionales. Se aplica un diseño cuasiexperimental (Propensity score matching) a partir de la Encuesta de Condiciones de Vida (ECV-2006). Los resultados confirman la existencia de efectos diferenciales positivos (con relación al impacto medio) de la política educativa en el caso de las mujeres y de los alumnos provenientes de hogares desfavorecidos, demostrando la existencia de heterogeneidad en el impacto de la política analizada.
Implantación de recursos didácticos digitales en asignaturas de Organización de Empresas
2013
El objetivo de este artículo es presentar el protocolo de implantación de diversas herramientas didácticas, así como el nivel de satisfacción de los estudiantes que las utilizan. Los resultados muestran, primero, que no es posible crear un único protocolo aplicable a todos los recursos, debido a las diferencias en los objetivos didácticos existentes. Segundo, la valoración que los estudiantes hacen de la utilización de los recursos es muy positiva, aunque existen algunas diferencias entre las distintas herramientas. Estos resultados permiten mejorar los recursos y adecuarlos al perfil de los estudiantes para que éstos puedan sacar el mayor provecho posible.
Does plant growth phase determine the response of plants and soil organisms to defoliation?
2005
Abstract To test a hypothesis that the effects of defoliation on plant ecophysiology and soil organisms depend on the timing of defoliation within a growing season, we established a greenhouse experiment using replicated grassland microcosms. Each microcosms was composed of three plant species, Trifolium repens , Plantago lanceolata and Phleum pratense , growing in grassland soil with a diverse soil community. The experiment consisted of two treatment factors—defoliation and plant growth phase (PGP)—in a fully factorial design. Defoliation had two categories, i.e. no trimming or trimming a total of four times at 2 week intervals. The PGP treatment had four categories, i.e. 1, 3, 7 or 13 wee…
Didactic proposal to change misconceptions about the contribution of the fusion of the ice to the rise in sea level
2020
En la actualidad existen muchos estudios acerca del conocimiento teórico de la población sobre el cambio climático. Los resultados de estos estudios muestran la existencia de confusiones e ideas alternativas respecto a determinados fenómenos y conceptos básicos de gran importancia, las cuales constituyen un serio obstáculo para el aprendizaje en educación ambiental. En este trabajo se analiza una de esas ideas, relacionada con el impacto directo que tiene la fusión del hielo flotante en el aumento del nivel del mar. Concretamente, se muestra una primera aproximación respecto a su extensión y fortaleza entre alumnado de secundaria y profesorado en formación, detallando a su vez una estrategi…
Mathematical Modeling in SecondaryEducation: A User's Manual
2019
[EN] One of the main problems that arise when implementing a mathematical modeling task to the secondary classroom is the lack of a detailed description, from the didactic perspective, that helps and guides the in-service teachers in the implementation of this type of activity and that allows them to identify which are the learning objectives being pursued; if this kind of activities t within the oficial curriculum; the type of tasks that allow these objectives to be achieved; how to carry out their evaluation or what methodology to use. In this article we will address all these aspects from the perspective of a classroom experience, detailing each of the phases involved in the implementati…
