From bus to tramway: Is there an economic impact of substituting a rapid mass transit system? An empirical investigation accounting for anticipation …
2018
Abstract Hedonic pricing models and price equations have been extensively used to retrieve the implicit prices of urban externalities through real estate markets. Many applications have been devoted to investigating the impact of new mass transit systems, such as rail infrastructures. However, the implementation of such infrastructures usually takes some time and markets can react with an anticipation effect that can vary according to the different development phases. Moreover, the impact may be different if it acts as a substitute to existing rapid transit services. This paper focuses on the impact of substituting bus rapid transit (BRT) for light rail transit (LRT) services, taking into a…
Port expansion and negative externalities: a willingness to accept approach
2015
Port expansion has been seen as the origin of negative externalities, affecting local residents’ well-being and contributing to the poor public image of ports. In this study, the contingent valuation method is used to estimate the costs borne by local residents as a consequence of the negative externalities derived from the growth of the Port of Valencia (Spain) in the last 30 years. As transport project appraisal has become more complex, this technique complements existing methodologies in this field, such as the social cost benefit analysis and the multicriteria analysis. Given the perceived property rights of families that have been living close to the port for a long time, a willingness…
Transport Logistics and Modal Split of Spanish Exports to Europe: Empirical Evidence
2006
This article attempts to find the determinants of mode choice decisions for Spanish shipments to Europe and North Africa in four productive sectors that presents differentiated transport logistics. To this end, exhaustive fieldwork was carried out and a database constructed, including 1251 observations collected from transport decision-makers. A mixed logit is used to estimate a modal choice model, consistent with economic theory of modal choice in a price-time reliability framework. The main findings are that quality attributes of service influence modal choice only for the relatively high-value sectors whereas relatively low-value sectors are mainly affected by transport costs. In terms o…
Évaluation de l'efficacité externe de la formation des agriculteurs
1997
Alain Mingat und Nelly Stephan, Bewertung der externen Effektivität landwirtschaftlicher Ausbildung. In diesem Beitrag soill die externe Effektivität der Ausbildung der Landwirte bewertet werden. Dabei soll festgestellt werden, ob besser ausgebildete Landwirte effizienter als weniger gut ausgebildete sind. Die durchgeführte Untersuchung erlaubte die Wirksamkeit der Ausbildung in zwei Phasen zu untersuchen : zum Zeitpunkt der Niederlassung in einem landwirtschaftlichen Betrieb, wo der Landwirt die Ausrichtung seines Betriebs festlegt, und während dieser Niederlassung, urn die Fähigkeit zur Führung dieses Betriebs zu bewerten. Auch wenn die Anhebung des technischen Ausbildungsniveaus ein wich…
EXTERNAL RECIRCULATION IN PRS TYPE TURBINE: EXPERIMENTAL AND NUMERICAL RESULTS.
2022
Cavitation is a relevant phenomenon for structural safety and noise level in hydraulic turbines, occurring when water pressure falls below the vapor value at a given temperature. In this case bubbles of vapor grow inside the liquid and move along with it. When the pressure returns above the vapor value the bubble collapses, and the pressure can locally achieve very high values, up to 7000 bars (Kumar & Saini, 2010). Moreover, if the bubble was confined also by the solid wall of a blade, the solid particles suspended in the fluid can be transported by the fluid ones and hit the solid wall at very high velocity, generating erosion. Cavitation is also the source of high frequency noise, ve…
Pensar Históricamente : la evaluación en la PAU de Historia de España
2016
La Tesis Doctoral analiza el grado de desarrollo de pensamiento histórico alcanzado por los alumnos preuniversitarios, tomando como referencia la evaluación externa realizada tras finalizar 2o de Bachillerato. Dos han sido las fuentes de información fundamentales en nuestra investigación. Por una parte, los protocolos de examen de las pruebas de Historia de España propuestas por las universidades de las 17 Comunidades Autónomas. Y por otra, las respuestas de los alumnos, sobre una muestra de 300 exámenes, seleccionada de las Universidades de Valencia y Santiago de Compostela. Se trata de una investigación que nos ha exigido combinar diferentes métodos de investigación, cuantitativos y cuali…
Premis, càstigs i educació
2008
Els autors defensen que el costum i la llei confi guren la legalitat i la moralitat socials i determinen el nostre comportament, alhora que qüestionen els resultats 'esperats' de l'aplicació mecànica dels premis i càstigs en educació. Distingeixen el control extern 'supervisió' i l'intern 'motivació' en l'esdevenir dels comportaments analitzats, en relació a l'aplicació d'aquelles sancions i tot seguit aborden l'estudi monogràfi c des del conductisme, des del cognitivisme i des de la perspectiva moral. Ara aborden la complexitat contextual de la intervenció pedagògica i les alternatives possibles des dels plantejaments actitudinals dels subjectes, per concloure que els premis tenen la fi na…
Considerations on acute otitis externa for its optimized treatment
2009
Abstract Introduction and objectives To evaluate the optimal treatment for diffuse acute otitis externa (DAOE) by means of a new staging system based on clinical and otoscopic findings. Methods Monitoring of otitis cases diagnosed at our centre over the last 21 months (n = 1026), taking into account those who returned for a second visit, either via the emergency room or with a prior appointment. Staging of otitis externa by degree of obstruction of the external auditory canal (EAC): under 25% (type I, n = 174); between 25% and 75% (type II, n = 277); over 75% (type III, n = 359); total obstruction due to organized oedema (type IV, n = 216). Results In most cases at an advanced stage, the ca…

Emotional suppression and breast cancer: validation research on the Spanish Adaptation of the Courtauld Emotional Control Scale (CECS).
2010
Emotional suppression has played an important role in the research on psychosocial factors related to cancer. It has been argued to be an important psychological factor predicting worse psychosocial adjustment in people with cancer and it may mediate health outcomes. The reference instrument in the research on emotional suppression is the Courtauld Emotional Control Scale (CECS). The present study analysed construct validity of a new Spanish adaptation of the CECS in a sample of 175 breast cancer patients. The results confirmed the proposal by Watson and Greer claiming that the CECS is composed of three subscales that measure different dimensions, but not independent, from emotional control…
