The taxonomy ofOreosparte(Apocynaceae: Asclepiadoideae)
2013
Oreosparte is a monotypic genus described as bearing strong similarities to Hoya (Marsdenieae), but separated from it based on the presence of a campanulate corolla with a contracted throat and lanceolate, spreading lobes. Its type specimen was destroyed during the fire at the Berlin herbarium in 1943. So far no suitable lectotype or further specimens belonging to the taxon were located. We report the finding of one specimen of Oreosparte collected from the type locality, allowing the selection of a neotype, to provide an extended description, and discussion of the morphological affinities with Hoya. Based on its morphology, despite being probably closely related to Hoya, we suggest that Or…
Estrategias locales de capacitación profesional y desarrollo local: el caso de Gandia, España
2009
En los últimos años, Gandia, una ciudad media del mediterráneo español, se ha convertido en un ejemplo de crecimiento económico mientras que, al mismo tiempo, enfrenta retos importantes. Estos incluyen la llegada de un relevante flujo de inmigrantes y la necesidad de adaptar el sistema económico local y el mercado de trabajo a un entorno cada vez más competitivo. Desde 1998 el Centro de Servicios Integrales de la municipalidad (CSI-COM) ha liderado un proceso de cooperación de los agentes locales para afrontar estos desafíos. CSI-COM constituye un ejemplo de buena práctica en la mejora del funcionamiento del mercado de trabajo local. Sus principales herramientas son la formación de recursos…
La propuesta sobre educación de la comisión para el estudio de los problemas españoles (1945)
2019
En este artículo se analiza y transcribe el texto redactado por un grupo de destacados profesores y pedagogos españoles exiliados, con especial atención a su contextualización. El grupo integraba la ponencia sobre educación de la Comisión de estudio de los problemas españoles, impulsada por la Unión de Profesores Españoles en el Extranjero. El documento final fue publicado en 1945 en la ciudad de México D.F.: en los Talleres tipográficos de B. Costa Amic, y ocupa 23 páginas. Se trata de un auténtico programa de actuación a llevar a cabo tras la restauración de la República en España, que en esas fechas tras finalizar la guerra en Europa, se pensaba cercana. A group of Spanish leading teache…
Institutional, pedagogical, psychosocial and socio-demographic factors related to academic performance at the University of Costa Rica: a multilevel …
2007
A multilevel analysis was conducted to predict final grades in courses from different majors for a sample, stratified by academic areas, of 848 students at the University of Costa Rica. A group of factors from institutional, socio-demographic, psychosocial and pedagogical aspects were employed as independent variables. The best predictor was the Admission Average, which combines grades from high school and an aptitude test score. Some non-cognitive variables were also explicative; the most important being the score on a scale of emotional intelligence. The methodology employed by the professor showed explicative power as well.
Maximización de la eficiencia y búsqueda de la celeridad en el arbitraje: entre el mito, la sublimación y la cuarta revolución industrial (4.0)
2018
En: Arbitraje: revista de arbitraje comercial y de inversiones. eISSN. 2603-9281. vol. 11, n. 1, 2018, pp 17-53 La globalización ha supuesto una transformación en el ámbito económico, generando un cambio de calidad y de cantidad en el tráfico económico, pero también en la posible conflictividad que puede provocarse. Esta situación ha incidido en el crecimiento de arbitrajes, apareciendo e impulsándose arbitrajes sectoriales, con protagonistas nuevos, con participación incluso del Estado en algunos arbitrajes. Todo ello ha favorecido cambios en las legislaciones nacionales arbitrales, en los reglamentos de las instituciones arbitrales, y en el modus operandi de operadores sociales, económico…

Near-infrared emissive bacteriochlorin-diketopyrrolopyrrole triads: Synthesis and photophysical properties
2019
International audience; The synthesis of unprecedented energy transfer triads containing a near-infrared (NIR) emissive bacteriochlorin subunit and two diketopyrrolopyrrole (DPP) moieties linked to each other via ethynyl or zero-carbon spacers is presented. Their optical and fluorescence properties were determined in CHCl3 and toluene. These photophysical measurements highlight the ability of DPP scaffold to act as an effective energy donor, which once excited in the range 450-550 nm resulting nearly exclusively NIR emission of hydroporphyrin (ETE > 96%). Since DPP dyes are valuable structurally tunable fluorophores that may be used in the construction of high-performance multicomponent pho…
Strategic Vision of a Euro-Mediterranean Port City: A Case Study of Palermo
2013
Italian harbours assume a decisive role in order to develop a Euro-Mediterranean web for maritime transportation. The geostrategic position of the Italian peninsula can be seen as a logistic platform at the centre of the maritime trades in the Mediterranean area, giving to its port cities the role of gateway of economic flows. The port poles, meant as hubs, are able to attract investments and create economic growth and territorial development through new operative models of urban usage and management. The management policies have to consider the environmental characteristics and distinctive features, respecting the identity of the places as concrete evidence of history, a source of intellec…
Failure by corrosion in PC bridges: A case history of a viaduct in Italy
2016
Purpose The paper illustrates a viaduct collapse due to corrosion phenomena. Moreover, a contribution to the issues related to both the control of existing structures and design methods to be followed for the construction of new buildings is provided. Design/methodology/approach The objectives were achieved by in situ observations and numerical analyses. The effects of corrosion phenomena are investigated, and the progressive collapse analysis is provided to be helpful in this case. Findings The damages induced by corrosion phenomena have caused the collapse of the viaduct taken in to account. The performed numerical analyses were able to reproduce the effects of corrosion in terms of redu…
Pupils Creative Activity in Textile Art at Competition
2014
The open olympiads of home economics and technologies encourage pupils of grades 5-9 to be creative in applying textile techniques. They also popularize textile art. Purpose of the study is to analyse the results of pupils’ creative work during the 10th open olympiad of home economics and technologies. Method: analysis of textile works. 376 pupils’ works from the 1st round and 85 works of the 2nd round have been analysed and assessed according to the following criteria: compliance with the task, unity of composition, composition of colours, compatibility of materials, originality, quality of the technical accomplishment, functionality.
