We estimate the total social income delivered by a simulated Stone pine ( Pinus pinea L.) afforestation investment in Huelva province, Spain. We consider the following private and public products: timber, pinecones, forestry conservation services, landowner amenities, landscape conservation, public recreation and carbon sequestration services. We show how total income of each single product is distributed into the partial rewards to labor and to environmental and manufactured assets. Results demonstrate that private income accounts on average for 46% of the total social income over the...

In this article, we focus on the need for “human computing” in data-rich ecosystems, notably as a consequence of data variety and typically for name disambiguation, and explore ways to manage it via online platforms for paid crowdsourcing. Based on several studies of Amazon Mechanical Turk, a well-established platform for matching data treatment tasks to human beings willing to carry them out, we illustrate the difficulties involved as requesters compete for the attention of workers. We suggest that researchers should shift from a technical analysis and tentative resolution of human...

We compare contingent valuation and choice modeling with field and eye-tracker data. Contrary to previous research, results yield significantly different structural models. These divergences remain for modified formats that minimize visual and cognitive differences between formats. We also find divergent results concerning information processing. In choice modeling, respondents devote more time to attributes, including the bid, although total answering time does not vary. Presenting several questions with varying attribute levels works for choice modeling but not for contingent valuation....

We investigate transitions among crop, grass and forest land uses in Andalusia (Spain) through an econometric model that uses individual land use decisions observed in the Corine Land Cover database as dependent variable, and net income, subsidies and biophysical and environmental factors as explanatory variables. Using multinomial logit models (fixed and random parameters), we identify both monetary and environmental and biophysical variables as significant in explaining land use decisions, but model performance significantly improves with the latter variables. We also identify the role...

The aim of this paper is to describe a matching and disambiguation methodology for the identification of author-inventors located in the same country. It aims to maximize precision and recall rates by taking into account national name writing customs in the name matching stage and by including a recursive validation step in the person disambiguation stage. An application to the identification of Spanish author-inventors is described in detail, where all SCOPUS 2003-2008 publications of Spanish authors are matched to all 1978-2009 EPO applications with Spanish inventors. Using this data, we...

This paper analyses public support for government spending on science and technology (S&T) and its determinants. It constructs hypotheses based on previous findings from two streams of research: public preferences for government spending and public understanding of science. Using data from a large national survey in Spain, it develops multivariate models to test the relevance of various predictors of public support for government spending on S&T. Findings identify several variables that are clear and consistent predictors of public support for government spending on science and...

A contingent valuation technique was applied to a 2004 sample of oak woodland landowners in California to assess its usefulness in estimating the non-market income and land price value of oak woodland properties. Non-market benefits have long been considered an important influence on rangeland landowners, but beyond comparing market production and land price, few studies have attempted to place a monetary value on them. Landowners were asked to estimate the maximum amount of earnings that they were willing to forgo before selling their property to invest in more commercially profitable non...

This paper defining the causes which underlie a public policy: Forum for immigrant participation. Little is known about the specific motivations which lead different governments’ decisions to institute such policies. This process cannot only refer to the theoretical objectives, but must consider the context in which certain Governments are brought to implement such policies while others do not. Hear submits a comparative analysis of 15 regional Immigration Forums in Spain. The aim is to verify that their creation responds to three variables: institutional isomorphism, response to demand...

Much has been made of the low returns on investment for western rangeland ranching. However, little work has been done to empirically compare these returns to the return that would be demanded by financial markets from assets with similar risk and return characteristics. This study uses historical forage productivity data from three locations in California’s Mediterranean rangelands to simulate financial statements for three hypothetical cow-calf ranches and measures the variability in return on investment from year to year. This performance is then compared to the actual performance of a...

España es un modelo de transición negociada, donde el cambio pacífico fue priorizado frente a la justicia transicional. Pero en el año 2000, las políticas de memoria se situaron en la agenda política. Esto provoco un reframing del pasado generador de conflicto. ¿Por qué y cómo se dio este proceso? Este artículo plantea que se relaciona con los intereses electorales, ideologías y búsqueda de impunidad de los partidos. Por un lado, estas variables explican las diferentes estrategias, códigos y argumentos que incentivaron situar el tema en la agenda. Pero por otro, también están relacionadas...
