Algunos episodios de la vida de Alejandro en la literatura medieval latina y romance

2015

La fuente clásica principal de la tradición medieval latina y vernácula de la vida de Alejandro Magno es la Historia de Alejandro de Quinto Curcio, principal referencia de la epopeya medieval Alexandreis de Gautier de Châtillon, que influyó grandemente a su vez en el Libro de Alexandre. Otra rama de la tradición la representa el Pseudo-Calístenes y sus traducciones latinas medievales, de Julio Valerio y del Arcipreste León de Nápoles. El estudio de algunos episodios significativos de la vida del emperador macedonio en diversas obras medievales latinas y vernáculas servirá para ponerlas en relación con esta doble tradición, la primera más histórica y la segunda novelesca. The main classical …

Memorias silenciadas en la construcción de los servicios sociales

2006

Joaquin.Garcia-Roca@uv.es Este artículo revisa la historia de la formación del sistema público de servicios sociales en España y expone «las rutas que no se navegaron», los derechos y las aspiraciones a que dieron lugar o conformaron unas expectativas, el origen de la des institucionalización, la pérdida de movimiento social y el desarrollo comunitario. El principio neoliberal y la exaltación de la gestión, la conquista de las profesiones y la ingeniería social han contribuido a silenciar un proceso que todavía se puede recuperar. ¿Cómo? El autor plantea que los servicios sociales han de ser capaces de producir significados personales tales como el sentido de pertenencia, la confianza, la i…

The ecological success of a social parasite increases with manipulation of collective host behaviour.

2015

Many parasites alter the behaviour of their host to their own advantage, yet hosts often vary in their susceptibility to manipulation. The ecological and evolutionary implications of such variation can be profound, as resistant host populations may suffer lower parasite pressures than those susceptible to manipulation. To test this prediction, we assessed parasite-induced aggressive behaviours across 16 populations of two Temnothorax ant species, many of which harbour the slavemaker ant Protomognathus americanus. This social parasite uses its Dufour's gland secretions to manipulate its hosts into attacking nestmates, which may deter defenders away from itself during invasion. We indeed find…

Student’s voice online: Experiences of PE in Finnish schools

2012

The aim of this descriptive study was to find out how people describe their experiences of physical education (PE) in Internet discussion forums. The data for this study were collected during one randomly chosen week in April 2007 via a GoogleTM search using the Finnish word ‘koululiikunta’ [school PE]. The first 200 hits lead into nine discussion forums, which were analysed by using qualitative content analysis. These nine discussion forums included all together 356 messages. For searching these discussion forums no criteria about the writers’ age, race, class, gender or other were set. The messages were coded with sequential classification and grouped into positive, negative and both posi…

Distribuzione di Bufo balearicus in Sicilia e rinvenimento di una zona ibrida tra le specie B. balearicus e B. siculus.

Oltre il gusto barocco: note su un ipotetico intreccio romano tra Robert Adam e Giuseppe Venanzio Marvuglia (1755-1759)

2020

Il saggio approfondisce il tema delle relazioni professionali nel corso della formazione romana del principale architetto del neoclassicismo siciliano, Giuseppe Venanzio Marvuglia (1729-1814). L’occasione nasce dallo studio analitico di un disegno attribuito all’architetto palermitano a confronto con un progetto dello studio di Robert Adam (1728-1792) conservato presso la Soane’s Collection di Londra. Il testo ripercorre le principali tappe della progettazione marvugliana nel passaggio dal tardo barocco al neoclassicismo, individuando tra le altre cose, per la prima volta, il modello di riferimento per villa Villarosa a Bagheria e portando all’attenzione quanto la rinomanza dell’architetto …

Análisis Biométricos del Sapo Verde Siciliano, Bufo siculus (Stöck et al. 2008), Población que Vive en Sicilia (Italia)

2013

Morphometry structure of Sicilian green toad from the Nature Reserve "Monte Pellegrino" (north-western Sicily) was studied. A total of 666 individuals (354 males and 312 females) were captured in 2003 during reproduction period. Meaningful differences have statistically emerged among the two sexes and the body weight is the best parameter (up to 92% correct classification), followed by the length of the body (up to 90% correct classification). The simultaneous use of all the examined characters only increases of 1% the probability for correct discrimination of the sex. In comparison to the dimension of other green toad populations studied by other authors, the body size of this sicilian pop…

Molecular phylogenetics and historical biogeography of the west-palearctic common toads (Bufo bufo species complex)

2012

In most pan-Eurasiatic species complexes, two phenomena have been traditionally considered key processes of their cladogenesis and biogeography. First, it is hypothesized that the origin and development of the Central Asian Deserts generated a biogeographic barrier that fragmented past continuous distributions in Eastern and Western domains. Second, Pleistocene glaciations have been proposed as the main process driving the regional diversification within each of these domains. The European common toad and its closest relatives provide an interesting opportunity to examine the relative contributions of these paleogeographic and paleoclimatic events to the phylogeny and biogeography of a wide…

Molecular Evolution and the Phylogenetic Relationships of the African Toad, Bufo danielae PERRET, 1977 (Salientia : Bufonidae)

1980

Abstract Phylogenetic relationships of the African toad Bufo danielae are investigated using a variety of biochemical approaches. Nuclear DNA content was assayed and compared to representatives of three species groups of African Bufo. Cellogel electrophoresis of plasma proteins was performed and patterns of B. danielae compared with those of representatives of the African B. regularis species complex. Finally microcomplement fixation analyses of albumin relationships of B. danielae and African Bufo were carried out. The strengths of the varied approaches for phylogenetic analysis are discussed. B. danielae appears most closely related to B. maculatus and B. pusillus, it being some 5-6 mill…

Bufones sobre lienzo. Nuevas miradas a la corte de los Austrias

2022

Esta tesis propone una regeneración bibliográfica e historiográfica de las representaciones pictóricas de enanos y bufones en el escenario de corte española de los Austrias durante los siglos XVI y XVII, con la voluntad de ofrecer hipótesis renovadas con que despejar parte de las profundas lagunas que envuelven estos peculiares retratos. Basándonos en un enfoque transversal y en el uso de nuevas herramientas metodológicas, atendemos a las inexploradas visualidad y recepción de estas imágenes y sus conexiones desde una perspectiva integradora que entrelaza las tradicionales investigaciones de la Historia del Arte con las miradas compartidas de la historia social y cultural de la corte, la im…
