Driver stress in five Spanish-speaking countries: Construct validity of the LatinSET
2020
Abstract Introduction Driver stress is a phenomenon many have studied in probably all five continents. It has been the focus of curiosity for all sorts of disciplines, and science has been unable to curb it, much less park it. Objectives This study aims to generate a unique scale that can be used in Spanish speaking countries regardless of culture or geography. Method and Materials A sample of 1954 drivers from Mexico, Guatemala, Costa Rica, Chile and Spain was comprised. Through this study, the original 21 items of the ISET (Stressful Situations in Transit Inventory, in Spanish) were used to carry out both an Exploratory Factorial Analysis as well as a Confirmatory Factorial Analysis. Resu…
Validation of a questionnaire of attributions to the detection of coincidences in academic work
2019
El plagio como tema de investigación en el contexto universitario no ha cesado de ser una preocupación constante debido a sus múltiples repercusiones. El presente estudio describe el proceso seguido en la validación del Cuestionario de atribuciones para la detección de coincidencias en trabajos académicos (CUDECO), cuya finalidad es evaluar la relevancia que tiene citar correctamente y detectar las causas que llevan a cometer plagio. A partir de una muestra de 2,331 estudiantes, se realiza un anális is de la fiabilidad como consistencia interna y un análisis factorial exploratorio (AFE) del instrumento. El análisis de la fiabilidad lleva a proponer un reajuste en el cuestionario inicialment…
The Catholic Nation under Liberalism. Perspectives on Religious Unity in Liberal Spain, 1808-1868
2015
El artículo estudia los significados históricos que tuvo la afirmación de la unidad religiosa de la nación española en el liberalismo decimonónico. A partir de las premisas historiográficas que han renovado las reflexiones en torno a las relaciones entre religión, política y nación, los autores analizan la herencia plural de los ilustrados del último tercio del siglo XVIII y el sentido de la homogeneidad confesional de la nación soberana, esbozada por la Constitución de 1812. La confesionalidad religiosa no impidió las posibilidades de emancipación individual. Por el contrario, el primer liberalismo tendió a un reforzamiento mutuo de las identidades religiosa y nacional, al tiempo que confi…
Actitudes docentes hacia los ejercicios de la Prueba de Acceso a la Universidad informatizada
2017
Resumen El presente artículo forma parte de la investigación desarrollada en el proyecto Paulex Universitas con la intención de obtener información sobre los ítems más aceptados por los profesores de 2º de Bachillerato de cara al inicio de la fase de pruebas para examinar la viabilidad de la puesta en funcionamiento de la Prueba de Acceso a la Universidad (PAU) asistida por ordenador en España y, más específicamente, los siguientes aspectos: la posibilidad de automatización de la prueba, las tipologías de ejercicios más populares entre los profesores y la relación entre las mismas. Un total de 214 profesores respondieron a un cuestionario diseñado según el método Delphi, destinado a averigu…
Primera persona del plural en los juicios orales. Valor representativo y estrategia atenuante
2018
El objetivo de este artículo es doble, pues nos proponemos estudiar los valores que puede desarrollar la primera persona del plural en los juicios orales y, en relación con ello, examinar si es posible identificar usos atenuantes asociados a este mecanismo referencial. Tras analizar nuestro corpus siguiendo una metodología cualitativa y cuantitativa, hemos podido observar que el uso de la primera persona del plural en este género no solo se debe al carácter representativo del sistema legal español o a las imposiciones de la tradición discursiva. Frecuentemente, el uso de la primera persona del plural (especialmente el plural de modestia y el plural sociativo) codifica un valor atenuante ori…
Interfaith Dialogue in Christian Norway: Enactment of Inclusive Religiosity as Civilized Behavior
2017
Despite sparse scholarly attention from non-activists, Scandinavian interfaith fora are gaining momentum as a response to societal transformations of increased migration, world conflicts, and politically motivated violence. Combining theories of interaction, ritual performance, and civilizing processes, the article conducts a case study of public interfaith meetings held by a local interfaith forum in Kristiansand in Norway. Analyzing the meetings as organized cultural encounters, the study explores the transformative aspects of the events and it points to how the enactment of civilized forms of cross-cultural religiosity created within and by these public interfaith meetings is interlinked…
Synthesis of Isoxazole and 1,2,3-Triazole Isoindole Derivatives via Silver- and Copper-Catalyzed 1,3-Dipolar Cycloaddition Reaction.
2016
International audience; The CuI-or Ag 2 CO 3-catalyzed [3+2] cycloaddition of propargyl-substituted dihydroisoindolin-1-one (3) with arylnitrile oxides 1a-d (Ar = Ph, p-MeC 6 H 4 , p-MeOC 6 H 4 , p-ClC 6 H 4) produces in good yields novel 3,5-disubstituted isoxazoles 4 of the ethyl-2-benzyl-3-oxo-1-((3-arylisoxazol-5yl)methyl)-2,3-dihydro-1H-isoindole-1-carboxylate type. With aryl azides 2a-d (Ar = Ph, p-MeC 6 H 4 , p-OMeC 6 H 4 , p-ClC 6 H 4), a series of 1,4-disubstituted 1,2,3-triazoles 6 (ethyl-2-benzyl-3-oxo-1-((1-aryl-1H-1,2,3-triazol-4-yl)methyl)-2,3-dihydro-1H-isoindole-1-carboxylates) was obtained. The reactions proceed in a regioselective manner affording exclusively racemic adduc…
A Tool to Assess Architectural Education from the Sustainable Development Perspective and the Students' Viewpoint
2021
[EN] Architectural education plays a fundamental role in achieving sustainable development by training future professionals who can contribute to sustainability through their practice. Nevertheless, to ensure the introduction of sustainable development in the education of future architects, it is fundamental to understand what is being done and what could be improved. Despite this, a big gap has been detected in the assessment of architectural education in Spain and worldwide. Thus, a close-ended questionnaire for students has been designed based on the outcomes from a literature review, exploratory interviews with specialists, and the qualitative analysis of two schools of architecture. Ad…
De novo biosynthesis of simple aromatic compounds by an arthropod ( Archegozetes longisetosus )
2020
The ability to synthesize simple aromatic compounds is well known from bacteria, fungi and plants, which all share an exclusive biosynthetic route—the shikimic acid pathway. Some of these organisms further evolved the polyketide pathway to form core benzenoids via a head-to-tail condensation of polyketide precursors. Arthropods supposedly lack the ability to synthesize aromatics and instead rely on aromatic amino acids acquired from food, or from symbiotic microorganisms. The few studies purportedly showing de novo biosynthesis via the polyketide synthase (PKS) pathway failed to exclude endosymbiotic bacteria, so their results are inconclusive. We investigated the biosynthesis of aromatic …
Desulfurization and ring opening of thiirane induced by tantalocene trihydride complexes: Synthesis, reactivity and X-ray structure of Cp′2Ta(=S)(S-i…
1999
The reaction of the tantalocene trihydride complexes Cp′ 2 TaH 3 1 (Cp′= η 5 -C 5 H 4 t Bu) or Cp″CpTaH 3 1′ (Cp″= η 5 -C 5 H 2 -1,2-Me 2 -4- t Bu) with propylene sulfide was found to proceed via an unprecedented sulfur transfer and regioselective ring opening reaction at once to yield sulfido-thiolato tantalocene complexes Cp′ 2 Ta(S)(S- i Pr) 2a whose structure has been determined by X-ray crystallography or Cp″CpTa(S)(S- i Pr) 2′a . Complex 1 reacts with ethylene sulfide to give Cp′ 2 Ta(S)(S–Et) 2b . The reactivity of 2a towards a variety of electrophilic moities has been investigated: protonation (with HBF 4 ) and alkylation (with MeI) reactions occur at the terminal sulfur ligand, …
