La protección de los bosques naturales a la luz del Derecho Ambiental Internacional y la constitución brasileña: ¿Serán capaces de salvar la Floresta…
2016
Este estudio objetiva elucidar las relaciones normativas sobre bosques naturales dentro de los diversos campos del Derecho Ambiental Internacional y del ordenamiento jurídico brasileño y proponer soluciones para aumentar la efectividad del control de la deforestación. Dado el carácter teórico del estudio se utilizaron las técnicas de investigación documental y bibliográfica. Inicialmente, fueron analizados la relevancia de los bosques naturales para el planeta y la humanidad; el régimen jurídico de los bosques en el ámbito de las convenciones de la biodiversidad, del cambio climático y la desertificación; y la rápida dilapidación del patrimonio forestal global y brasileño. A continuación, f…
Causalities between CO2, electricity, and other energy variables during phase I and phase II of the EU ETS
2010
The topic of this article is the analysis of the interplay between daily carbon, electricity and gas price data with the European Union Emission Trading System (EU ETS) for CO2 emissions. In a first step we have performed Granger causality tests for Phase I of the EU ETS (January 2005 until December 2007) and the first year of Phase II of the EU ETS (2008). The analysis includes both spot and forward markets—given the close interactions between the two sets of markets. The results show that during Phase I coal and gas prices, through the clean dark and spark spread, impacted CO2 futures prices, which in return Granger caused electricity prices. During the first year of the Phase II, the sho…
Evaluación de la calidad de los diagnósticos premortem de causas de muerte en las autopsias del Hospital Clínico Universitario de Valencia (1985-1992)
2009
Se estudiaron 998 autopsias realizadas en el Servicio de Anatomía Patológica del Hospital Clínico Universitario de Valencia entre 1985 y 1992, introducidas y procesadas en el Sistema Automatizado de Registro y Control de Anatomía Patológica (SARCAP) en el Hospital «Hermanos Ameijeiras» de La Habana, Cuba. Los principales resultados fueron: predominio del sexo masculino y las edades avanzadas; las principales causas básicas de muerte fueron los tumores malignos, la ateromatosis coronaria, la cirrosis hepática y el SIDA, y las principales causas directas de muerte fueron la bronconeumonía, la extensión del cáncer y el tromboembolismo pulmonar. Hubo 10,6% de discrepancias diagnósticas premorte…
Customer value in tourism and hospitality: Broadening dimensions and stretching the value-satisfaction-loyalty chain
2019
Abstract Customer value research consists of two main streams, with broad recognition in tourism literature: value dimensions (intra-variable perspective) and relationships among value, satisfaction and loyalty (inter-variable perspective). The conceptual framework reviews and categorizes graphically both streams, evidencing the need of research combining both perspectives. The empirical study uses PLS to validate among a sample of 340 hotel guests, a comprehensive causal model with a high number (eight) of value dimensions -functional (efficiency and excellence), social (status and esteem), hedonic (aesthetic and entertainment) and altruistic (ethics and escapism). Moreover, the model adds…
A Macroeconomic Analysis of Regional Migration in Finland, 1975-95
1999
This study analyzes regional migration in the 85 Finnish subregions during the period 1975-95 using data on net in-migration rates. Both cross-section and panel data methods are employed. The regression analysis reveals that the direction of net in-migration flows can be explained by a set of regionally differing characteristics. Unemployment rates, tax rates, and the share of primary production affect net in-migration negatively, whereas the share of higher education and the growth of regional incomes have a positive effect. This indicates that regional disparities may not be alleviated by migration, but there is some evidence for a cumulative causation growth pattern induced by net in-mig…
The disenchantment of professionals in a new, implemented model of primary health care in Spain: A structural equations model
1992
Abstract A new model of primary health care has been progressively implemented in Spain. Previous research (Peiro and Gonzalez-Roma 1991) suggested that the implementation of this new model has produced a kind of disenchantment—that is, an experience of negative surprise—among health care professionals involved. In the present paper, a structural equations model about the antecedents and consequences of the experience of surprise is tested in a sample of 432 health care professionals working in 44 Primary Health Care Teams (PHCT). The results obtained showed that the number of uncovered functions in the PHCTs, the discrepancy between actual and desired time allocation, and the assessment of…
Granger Causality Analysis of Transient Calcium Dynamics in the Honey Bee Antennal Lobe Network
2023
Odorant processing presents multiple parallels across animal species, and insects became relevant models for the study of olfactory coding because of the tractability of the underlying neural circuits. Within the insect brain, odorants are received by olfactory sensory neurons and processed by the antennal lobe network. Such a network comprises multiple nodes, named glomeruli, that receive sensory information and are interconnected by local interneurons participating in shaping the neural representation of an odorant. The study of functional connectivity between the nodes of a sensory network in vivo is a challenging task that requires simultaneous recording from multiple nodes at high temp…
