The late roman pottery imports in the East of Hispania Tarraconensis

Recent studies provided new data about late Roman imports (ARS, amphorae, lamps) in the coast of Hispania Tarraconensis. Concerning urban contexts (the ancient towns of Barcino, Tarraco and others) and rural settlements, the data allow us to identify the imports and the economic trends of the region from the 4th to the late 6th /early 7th centuries. We hope this paper to be an interpretative work of synthesis about the economic relationship between town and country in Catalonia and Northern Comunidad Valenciana in the Late Antiquity.

La “ciudad arqueológica” en el área catalana ante la irrupción del Islam

Se presenta un breve estado de la cuestión sobre la realidad arqueológica de los principales núcleos urbanos del este de la provincia Tarraconensis y a finales del Regnum Gothorum. Existe un nivel de conocimiento desigual para estas ciudades, fruto del contexto actual de la investigación, y también de una evolución histórica diferenciada, como consecuencia de unas características geopolíticas propias que, posiblemente, indujeron a una modificación de las jerarquías entre las ciudades. Planteamos la ciudad visigoda como el centro de gestión civil y religioso de una unidad territorial donde la arqueología identifica los vestigios de la arquitectura del poder, pero todavía no consigue definir con precisión los procesos domésticos inherentes a toda comunidad urbana. Conocemos globalmente los diferentes procesos de la desestructuración urbana de la Antigüedad tardía pero no los parámetros de la ocupación agrourbana de los recintos amurallados. Para este período histórico se supone que la redimensión demográfica del hecho urbano más una reducción de las relaciones económicas entre la ciudad y el territorio son factores determinantes de las nuevas ciudades visigodas, pero se reconoce una incertidumbre fruto de la dificultad arqueológica de estudiar las nuevas pautas constructivas y una cultura material más restringida.

La dimensió social del moviment priscil·lianista en el context de l'antiguitat tardana. Heretgia, lluita contra la institucionalització eclesiàstica i contestació social.

L'any 385, Priscil·lià i la resta del grup priscil·lianista era condemnat a la ciutat de Trèveris i, fruit de la ingerència determinant de l'usurpador Magne Màxim, es convertia en el primer heretge ajusticiat pel poder secular en nom de l'Església. Els fets de Trèveris, per bé que van significar el final de la disputa entre dos grups amb posicions antagòniques vers les característiques del nou cristianisme institucionalitzat, no van aconseguir acabar amb el priscil·lianisme. El moviment perdurà, especialment a la província de la Gallaecia, i Priscil·lià va esdevenir venerat com màrtir. L'Església, mentrestant, es fracturava per culpa de la competència jurisdiccional entre la institució clerical i el poder imperial. Aquest treball intenta ser un estat de la qüestió respecte a la dimensió social d'un moviment que, més enllà de l'eterna discussió entre la seva possible catalogació com a ortodòxia o heterodòxia, intenta contextualitzar el priscil·lianisme en el seu marc històric i els convulsos anys de les transformacions de l'antiguitat tardana.

Los espectaculos de la tradición romano-pagana en la obra de Paulino de Nola

In this paper we study the presence of elements related to Roman games in the work of the bishop Paulinus of Nola (355-431 AD). References to shows in his work are not as abundant as they occurs among his contemporaries. Nevertheless, many of these references possess a great importance for us. Certainly, they are similar to other allusions made by his contemporaries; however they express the opinion of one of the most famous and prestigious bishops of the Late Antiquity about these popular exhibitions. In his writings we can see his criticism of the waste of wealth in the organization of the Roman games, and also the use of a metaphorical language with ludical reminiscences whose origins go back to Paul of Tarsu

El poblament tardoantic al sector meridional de la Tarraconensis (sud de Catalunya i nord del País Valencià). Concomitàncies i diferències

Les darreres recerques dutes a terme en el Projecte Ager Tarraconensis (PAT) han permès augmentar considerablement els coneixements existents sobre l’antiguitat tardana al territorium de Tarraco, tema que ja havíem estudiat parcialment en la nostra tesi doctoral (1992), que inclou també altres àrees del Camp de Tarragona no incloses al PAT. D’altra banda, en els darrers anys hem tingut també ocasió d’estudiar parcialment el poblament antic a la zona de les terres de l’Ebre i al nord del País Valencià, molt especialment a les comarques de l’Alt Palància i la Plana de Castelló. El conjunt d’aquests estudis ens permet plantejar una visió general sobre el poblament tardoantic en una zona determinada que correspon a la part costanera meridional de l’antiga provincia Tarraconensis, amb els límits i la denominació que rep a partir de la divisió de Dioclecià. L’estudi comparatiu del poblament tardoantic d’aquestes àrees permet contrastar, a més de punts en comú, també algunes diferències, tant en el diferent grau de pervivència dels hàbitats després de la crisi del segle III com en l’aparició de nous tipus d’hàbitats (poblats en altura) que no apareixen en totes les àrees, sinó només en les més meridionals. S’aborda també la problemàtica de l’existència d’unes poques vil·les luxoses durant el segle IV (especialment la controvertida de Centcelles), en contrast amb altres hàbitats més modestos, així com el pas de la vil·la a un altre tipus de poblament dispers.

Las últimas importaciones romanas de cerámica en el este de Hispania Tarraconensis: una aproximación

En los últimos años, se han publicado diversos estudios que han permitido tener un buen conocimiento sobre las importaciones (terra sigillata, ánforas, lucern as) en la costa de la antigua Hispania Tarraconensis en época romana tardía. Este conocimiento, concerniente a los contextos urbanos (las ciudades antiguas de Barcino, Tarraco y otras) y los establecimientos rurales, permite determinar las tendencias de las importaciones y la economía en esta área entre los siglos IV y finales del VI e inicios del VII d.C. El aumento de datos necesita una interpretación, orientada hacia la determinación de las tendencias del comercio y las importaciones, y la relación económica entre la ciudad y el campo en la actual Cataluña en la Antigüedad Tardía. Con esta contribución, esperamos poder colaborar en la elaboración de un trabajo interpretativo de síntesis sobre estos aspectos.

El territorio y la ciudad de Tarraco

This paper presents a brief description of the archaeological research in the territory and in the city of Tarraco, the ancient capital of provincia Hispania Tarraconensis and one of the main centres for the spread of Hispanic Christianity. Althoug Tarraco was the last capital under imperial control and the firs Hispanic metropolitan see, the city had only a secondary role by comparison with other Hispanic cities during late antiquity. This evolution shaped the development of Tarraco during the 7th century, but archaeologists identify an important architectural vitality still in the 6th century at the same time as other episcopal cities were evolving. During this period, the final Christianization of the symbolic spaces of ancient paganism took place, establishing the ideological basis of medieval urbanism that is still preserved today. The paper also interprets the sites through raising key questions as well as describing rural settlements, where archaeological knowledge is not so far advanced, due in part to the difficult nature of archaeological research, and in part to the need to study new construcitve models, as well as to the systematic collection of the relevant material culture.

Ecological conflicts and valuation - mangroves vs. shrimp in the late 1990s

Shrimps are produced in two different ways. They are fished in the sea (sometimes at the cost of turtle destruction) or they are "farmed" in ponds in coastal areas. Such aquaculture is increasing around the world as shrimps become a valuable item of world trade. Mangrove forests are sacrificed for commercial shrimp farming. This paper considers the conflict between mangrove conservation and shrimp exports in different countries.Who has title to the mangroves, who wins and who loses in this tragedy of enclosures? Which languages of valuation are used by different actors in order to compare the increase in shrimp exports and the losses in livelihoods and in environmental services? The economic valuation of damages is only one of the possible languages of valuation which are relevant in practice. Who has the power to impose a particular language of valuation?

Late bloomer or language impaired? Screening the speech of a Spanish-English bilingual toddler for early signs of language impairment

This case study presents corpus data gathered from a Spanish-English bilingual child with expressive language delay. Longitudinal data on the child’s linguistic development was collected from the onset of productive speech at age 1;1 until age 4 over the course of 28 video-taped sessions with the child’s principal caregivers. A literature review focused on the relationship between language delay and persisting disorders—including a discussion of the frequent difficulty in distinguishing between the two at early stages of bilingual development—is followed by an analysis of the child’s productive development in 2 distinct phases. An attempt is made to assess the child’s speech at age 4 for preliminary signs of SLI and to consider techniques for identifying ‘at risk’ bilingual children (that is, those with productive language delay, poor oral fluency, and family history of language problems) based on samples of recorded and transcribed speech.

Cholesterol transport from late endosomes to the Golgi regulates t-SNARE trafficking, assembly, and function

Cholesterol regulates plasma membrane (PM) association and functioning of syntaxin-4 and soluble N-ethylmaleimide-sensitive fusion protein 23 (SNAP23) in the secretory pathway. However, the molecular mechanism and cellular cholesterol pools that determine the localization and assembly of these target membrane SNAP receptors (t-SNAREs) are largely unknown. We recently demonstrated that high levels of annexin A6 (AnxA6) induce accumulation of cholesterol in late endosomes, thereby reducing cholesterol in the Golgi and PM. This leads to an impaired supply of cholesterol needed for cytosolic phospholipase A2 (cPLA2) to drive Golgi vesiculation and caveolin transport to the cell surface. Using AnxA6-overexpressing cells as a model for cellular cholesterol imbalance, we identify impaired cholesterol egress from late endosomes and diminution of Golgi cholesterol as correlating with the sequestration of SNAP23/syntaxin-4 in Golgi membranes. Pharmacological accumulation of late endosomal cholesterol and cPLA2 inhibition induces a similar phenotype in control cells with low AnxA6 levels. Ectopic expression of Niemann-Pick C1 (NPC1) or exogenous cholesterol restores the location of SNAP23 and syntaxin-4 within the PM. Importantly, AnxA6-mediated mislocalization of these t-SNAREs correlates with reduced secretion of cargo via the SNAP23/syntaxin-4¿dependent constitutive exocytic pathway. We thus conclude that inhibition of late endosomal export and Golgi cholesterol depletion modulate t-SNARE localization and functioning along the exocytic pathway.

A clathrin-dependent pathway leads to KRas signaling on late endosomes en route to lysosomes

Ras proteins are small guanosine triphosphatases involved in the regulation of important cellular functions such as proliferation, differentiation, and apoptosis. Understanding the intracellular trafficking of Ras proteins is crucial to identify novel Ras signaling platforms. In this study, we report that epidermal growth factor triggers Kirsten Ras (KRas) translocation onto endosomal membranes (independently of calmodulin and protein kinase C phosphorylation) through a clathrin-dependent pathway. From early endosomes, KRas but not Harvey Ras or neuroblastoma Ras is sorted and transported to late endosomes (LEs) and lysosomes. Using yellow fluorescent protein¿Raf1 and the Raichu-KRas probe, we identified for the first time in vivo¿active KRas on Rab7 LEs, eliciting a signal output through Raf1. On these LEs, we also identified the p14¿MP1 scaffolding complex and activated extracellular signal-regulated kinase 1/2. Abrogation of lysosomal function leads to a sustained late endosomal mitogen-activated protein kinase signal output. Altogether, this study reveals novel aspects about KRas intracellular trafficking and signaling, shedding new light on the mechanisms controlling Ras regulation in the cell.

Late and post-Hercyniam low temperature veins in the Catalonian Coastal Ranges

Many of the veins enclosed within the Paleozoic basement of the Catalonian Coastal Ranges show severa1 common characteristics: low temperature of formation (between 75 and 200C), the presence of complex polisaline fluids and a certain relationship to the pretriassic paleosurface. Mineralogical composition and age are variable, ranging from Pb-Zn veins with carbonate gangue of late Hercynian age through metal poor fluorite rich veins to barite rich veins of Triasssic age. Mineralizing fluids are not related to late Hercynianmagmatism and deposition took place in active fractures developed either in extensional as in compressive regimes.

Late Neogene lacustrine record and paleogeography in the Quillagua-Llamara basin, Central Andean fore-arc (Northern Chile)

The Cenozoic QuillaguaLlamara basin (northern Chile, Central Andes) is an asymmetrical, intramassif fore-arc basin with a relatively wide northern sector separated from a narrower southward extension by a basement threshold. The north- ern sector was characterised by a noticeable Oligocene?late Neogene alluvial-fan and lacustrine dominated deposition which resulted in sequences up to 900 m thick, whereas the southern sector was often a bypass zone with thinner fluvial and lacustrine sediment accumulation.

Greece and Platonic Love in E. M. Forster's Maurice, or the greatness and limits of Antiquity as a source of inspiration.

The aim of this article is to show how, although the evident idealization of Greece and Platonic love throughout the Victorian-Edwardian England, both also show their limits. In order to make it clear the author refers constantly to the implicit Greek texts such as Plato's Symposium and Phaedrus and perhaps even to Plutarch¿s Eroticus in search of a Classical Tradition which is highly significant in order to understand that England at the beginning of the twentieth century.
