Arquitectura y urbanismo en la conturbación barcelonesa. Ramon Puig Gairalt arquitecto municipal de l'Hospitalet de Llobregat (1912-1937)

[spa]En este artículo planteamos que significaron los trabajos de los arquitectos Ramon y Antoni Puig Gairalt, que abarcan desde la primera década del siglo XX hasta el año 1937 y que aún perviven en muchas de las localidades del territorio catalán donde intervinieron. Hablamos en plural de los Puig Gairalt porque fueron dos hermanos, Ramon y Antoni, aunque en L'Hospitalet de Llobregat las intervencions corresponden mayoritariamente a Ramon Puig Gairalt. En la actualidad muchas de las obras perduran y, como valores patrimoniales, han llegado hasta nosotros. Como es bien sabido, el patrimonio de muchas poblaciones y ciudades forma parte de la memoria con la que una colectividad se identifica. A lo largo del tiempo, han ido conformando su paisaje urbano y cualquier colectividad que transita por su territorio, establece un vínculo muy directo sea éste o no de carácter monumental porque de hecho se ha convertido en signo de su identidad.

Regional Data Transmission Network

The globalization and development of an information society promptly change shape of the modern world. Cities and especially megacities including Saint-Petersburg are in the center of occuring changes. As a result of these changes the economic activities connected to reception and processing of the information now play very important role in economy of megacities what allows to characterize them as "information". Despite of wide experience in decision of information questions Russia, and in particular Saint-Petersburg, lag behind in development of information systems from the advanced European countries. The given master's thesis is devoted to development of an information system (data transmission network) on the basis of wireless technology in territory of Saint-Petersburg region within the framework of FTOP "Electronic Russia" and RTOP "Electronic Saint-Petersburg" programs. Logically the master's thesis can be divided into 3 parts: 1. The problems, purposes, expected results, terms and implementation of the "Electronic Russia" program. 2. Discussion about wireless data transmission networks (description of technology, substantiation of choice, description of signal's transmission techniques and types of network topology). 3. Fulfillment of the network (organization of central network node, regional centers, access lines, description of used equipment, network's capabilities), financial provision of the project, possible network management models.

Activity patterns and foraging behaviour of Audouin's gulls at the Ebro Delta, NW Mediterranean.

Twenty Audouin´s gulls, Larus audouinii, breeding in the Ebro Delta (NW Mediterranean) were radio-tracked in 1998 to study their foraging behaviour and activity patterns. Some detrimental effects of tagging on the breeding success of the birds were detected, especially when both members of the pair were tagged. The results were actually constrained by the low number of locations due to natural breeding failure and failure in tag emission, as well as the adverse effect of tagging. However, through a combination of aircraft surveys at sea and a fixed station for automatic tracking of the presence of the birds at the colony, novel individual-based information of home ranges and activity patterns was obtained. Trawler fishing activity seemed to influence both the foraging range and habitat use: while trawlers operated, gulls overlapped their fishing grounds with vessels, probably to scavenge on discards. Very few locations were obtained during a trawling moratorium period, although they were all recorded in coastal bays and terrestrial habitats. During the trawling activity period, gulls ranged over a minimum convex polygon area of 2900 km2. Gulls were tracked up to 40 km from the colony, but some individuals were observed beyond 150 km while still breeding. Arrivals and departures from the colony were in accordance with the trawling timetable. However, most birds also showed some nocturnal foraging activity, probably linked to active fishing of clupeoids (following diel migrations) or to the exploitation of purse-seine fishing activity. Foraging trips lasted on average 15 hours: males performed significantly shorter trips than females, which spent more time outside the colony. The proportion of nocturnal time involved in the foraging trips was the same for males and females, but whilst all males initiated their trips both during the day and at night, some females only initiated their trips during the day. Hatching success was found to be related to foraging effort by males. Gulls spent on average ca. 38% of their time budget outside the nesting territory, representing the time devoted mainly to flying, foraging and other activities.

Snakefly diversity in Early Cretaceous amber from Spain (Neuropterida, Raphidioptera)

The Albian amber from Spain presently harbors the greatest number and diversity of amber adult fossil snakeflies (Raphidioptera). Within Baissopteridae, Baissoptera? cretaceoelectrasp. n., from the Peñacerrada I outcrop (Moraza, Burgos), is the first amber inclusion belonging to the family and described from western Eurasia, thus substantially expanding the paleogeographical range of the family formerly known from the Cretaceous of Brazil and eastern Asia. Within the family Mesoraphidiidae, Necroraphidia arcuatagen. et sp. n. and Amarantoraphidia ventolinagen. et sp. n. are described from the El Soplao outcrop (Rábago, Cantabria), whereas Styporaphidia? hispanicasp. n. and Alavaraphidia imperterritagen. et sp. n. are describedfrom Peñacerrada I. In addition, three morphospecies are recognized from fragmentary remains. The following combinations are restored: Yanoraphidia gaoi Ren, 1995, stat. rest., Mesoraphidia durlstonensis Jepson, Coram and Jarzembowski, 2009, stat. rest., and Mesoraphidia heteroneura Ren, 1997, stat. rest. The singularity of this rich paleodiversity could be due to the paleogeographic isolation of the Iberian territory and also the prevalence of wildfires during the Cretaceous.

The Effects of a Nematode Lungworm (Rhabdias hylae) on its Natural and Invasive Anuran Hosts.

Biological invasions can bring both the invader and native taxa into contact with novel parasites. As cane toads ( Rhinella marina ) have spread through Australia, they have encountered lungworms (Rhabdias hylae) that occur in native frogs. Field surveys suggest that these lungworms have not host-switched to toads. In our laboratory studies, R. hylae infected cane toads as readily as it infected native frogs, but failed to reach the lungs of the novel host (i.e., were killed by the toads' immune response). Plausibly, then, R. hylae might reduce the viability both of their native hosts (frogs, that can exhibit high parasite burdens) and cane toads (that must deal with infective larvae traveling through the host body). Our laboratory trials suggest, however, that the impacts of the parasite on infected anuran hosts (both frogs and toads) were minimal, with no significant decrements to host survival, activity, growth, or locomotor performance. Ironically, the lack of impact of the parasite on its native hosts appears to be an outcome of co-evolution (frogs tolerate the lungworm), whereas the lack of impact on the novel host is due to a lack of co-evolution (toads can recognize and eliminate the lungworm).

Necrópolis de incineración y prácticas funerarias en el noreste de la Penínnsula Ibérica durante el Bronce Final y la Primera Edad del Hierro

[spa]En este artículo presentamos un estado de la cuestión sobre las necrópolis de incineración del Bronce Final y Primera Edad del Hierro en el noreste peninsular. Para ello, analizamos el ritual funerario, la organización interna de las necrópolis y muy especialmente su arquitectura funeraria para, en base a ella, caracterizar el proceso de regionalización que se observa en el territorio.

Local capitalism and neoliberalization in a Shenzhen former lineage-village

This article examines the process of neoliberalization in the Shenzhen special economic zone in Guangdong province, China. Building on the case study of a former peasant and almost single-lineage village that has become a part of Shenzhen city, I show how neoliberal principles aimed at advancing the transition to capitalism are combined with and countered by other ethical traditions. Owing to the long-standing conception of the lineage as an enterprise, the maintenance of the lineage structure in the transformation of the rural collectives has offered fertile ground for the emergence of a local capitalist coalition. Yet the current discourses on the necessity of obliterating the remains of the collective economy and introducing individual ownership run counter to the collectivist values of the lineage-village community and the embeddedness of its economy in kinship and territorial ties. I further illustrate this discordance by the way in which the villagers managed to save their founding ancestor's gravesite following government requests to clear the land by removing tombs. These policies form a complex blend of state interventions in the economy, neoliberal governance and Confucian principles.

Territorialisation des politiques énergétiques dans l'agglomération franco-valdo-genevoise : la planification énergétique comme opportunité de réaménagement des zones frontières ?

La présente recherche traite des défis posés à l'action publique territoriale par la transition énergétique, transition désormais érigée au rang de priorité par les autorités françaises et suisses, comme plus globalement européennes. Elle prend pour cela appui sur une analyse des démarches de planification énergétique territoriale menées entre 2007 et 2014 sur le territoire franco-valdo-genevois (agglomération du « Grand-Genève »). Considérées comme des laboratoires d'expérimentation de la territorialisation des politiques énergétiques, ces démarches sont ici examinées selon une perspective institutionnaliste et pragmatiste visant à mettre lumière les éléments qui interviennent dans la délimitation du champ des possibles en matière d'action publique énergétique et territoriale. Ce positionnement découle des évolutions observées sur le territoire franco-valdo-genevois durant la période d'étude (chapitre 1). Il découle plus précisément du constat de récurrence de certains points de blocage rencontrés aussi bien dans les démarches de planification énergétique elles-mêmes que dans les travaux méthodologiques qui ont pu être réalisés parallèlement à ces démarches, dans le but d'en affiner les outils techniques et organisationnels de mise en oeuvre. Ainsi, le point de départ de la présente recherche est le constat selon lequel on peine tout autant à construire des solutions énergétiques appropriables et réalisables par les acteurs des territoires concernés qu'à reconfigurer les outils de production de ces solutions. De ce constat découle l'intérêt porté aux cadres institutionnels qui régissent ces planifications énergétiques territoriales. Définis comme l'ensemble des repères - formels et informels - qui rendent possibles en même temps qu'ils contraignent les interactions territorialisées entre les acteurs, ces cadres institutionnels sont placés au coeur de la grille de (re)lecture des expériences de planification énergétique territoriale établie au chapitre 2 de la thèse. En référence aux concepts institutionnalistes et pragmatistes sur lesquels elle prend appui, cette grille conduit à appréhender ces expériences comme autant d'enquêtes contribuant, à travers le travail de mobilisation et construction de représentations territoriales auquel elles donnent lieu, à l'équipement sociocognitif d'un champ d'intervention territorial spécifique. Partant de l'hypothèse selon laquelle les potentialités comme les limites associées à l'équipement sociocognitif de ce champ orientent les possibilités d'action collective, la réflexion consiste en une application de cette grille à une trentaine d'expériences de planification énergétique territoriale. Cette application s'effectue en deux temps, correspondant à deux niveaux de lecture de ces démarches. Le premier porte sur les dispositifs organisationnels et les modalités d'interactions entre les cultures d'action qu'elles réunissent (chapitre 3). Le second se concentre davantage sur les supports cognitifs (représentations territoriales) autour desquels se structurent ces interactions (chapitre 4). Présentés dans le dernier chapitre de la thèse (chapitre 5), les enseignements tirés de ce travail de réexamen des démarches franco-valdo-genevoises de planification énergétique territoriale sont de deux ordres. Ils portent d'abord sur les caractéristiques des cadres institutionnels existants, la manière dont ils orientent ces démarches et délimitent les évolutions possibles dans les modes d'action collective et plus particulièrement d'action publique qui y sont associés. Mais ils portent aussi sur les potentiels de changement associés à ces démarches, et sur les pistes envisageables pour mieux valoriser es potentiels, dont l'activation passe par des évolutions profondes des systèmes institutionnels en place. -- In France as in Switzerland, local authorities stand out as leading players of energy transition, a transition that requires an important renewal of public intervention instruments. It is the stakes and the conditions of such a renewal that the present work aims to examine, based on the experiments of territorial energy planning led on the franco-valdo-genevan cross-border territory. Conceived as initiatives of relocation of the energy supply system, these energy planning initiatives are examined through an institutionalist and pragmatic « reading template ». This « reading template » consists of seeing these energy planning initiatives as pragmatist inquiries aiming, through a collective work of cognitive equipment of the territorial franco-valdo-genevan field of intervention, at the reconstruction of the means of coordination between people about their material, organizational and political territory. It opens towards a double reading of the energy planning initiatives. The first one concentrates on the organizational dimension of these inquiries - i.e. on the cultures of action which they gather and the modalities of interaction between them - whereas the second focuses on the cognitive substance which represents the medium of the interactions. This double reading provides insights at various levels. The first one concerns the (cognitive) territorial field of intervention that these energy-planning experiments contribute to draw. A field which, although better and better characterized in its technical dimensions, remains at the same time limited and " deformed " so that it values more the fossil energy systems, from which we want to release ourselves, than the renewable ones, which we would like to replace them with. The second level of teaching concerns the processes of production of territorial knowledge (PPTK) which presides over the demarcation and « equipment » of the territorial field of intervention. Examined through the institutional norms and the culture of action at stake in them, this PPTK turns out to create a sociocognitive "cross-border" area, the kind of area that could shelter the desired reconfigurations...on the condition that they are beforehand correctly "equipped", in cognitive and also in organizational terms. The determining factor for the quality of this equipment is concentrated in the third category of teaching. Starting with the opportunities created by these energy planning experiments concerning the renewal of public intervention instruments, these elements also allow us to take a new look at the urban area project under construction in this cross-border territory, a project th t shows itself closely linked to the energy experiments through a common challenge of territorialisation.

Estimations of topographically correct regeneration to nerve branches and skin after peripheral nerve injury and repair.

Peripheral nerve injury is typically associated with long-term disturbances in sensory localization, despite nerve repair and regeneration. Here, we investigate the extent of correct reinnervation by back-labeling neuronal soma with fluorescent tracers applied in the target area before and after sciatic nerve injury and repair in the rat. The subpopulations of sensory or motor neurons that had regenerated their axons to either the tibial branch or the skin of the third hindlimb digit were calculated from the number of cell bodies labeled by the first and/or second tracer. Compared to the normal control side, 81% of the sensory and 66% of the motor tibial nerve cells regenerated their axons back to this nerve, while 22% of the afferent cells from the third digit reinnervated this digit. Corresponding percentages based on quantification of the surviving population on the experimental side showed 91%, 87%, and 56%, respectively. The results show that nerve injury followed by nerve repair by epineurial suture results in a high but variable amount of topographically correct regeneration, and that proportionally more neurons regenerate into the correct proximal nerve branch than into the correct innervation territory in the skin

Extended Endoscopic Endonasal Approaches for Cerebral Aneurysms: Anatomical, Virtual Reality and Morphometric Study

Introduction. The purpose of the present contribution is to perform a detailed anatomic and virtual reality three-dimensional stereoscopic study in order to test the effectiveness of the extended endoscopic endonasal approaches for selected anterior and posterior circulation aneurysms. Methods. The study was divided in two main steps: (1) simulation step, using a dedicated Virtual Reality System (Dextroscope, Volume Interactions); (2) dissection step, in which the feasibility to reach specific vascular territory via the nose was verified in the anatomical laboratory. Results. Good visualization and proximal and distal vascular control of the main midline anterior and posterior circulation territory were achieved during the simulation step as well as in the dissection step (anterior communicating complex, internal carotid, ophthalmic, superior hypophyseal, posterior cerebral and posterior communicating, basilar, superior cerebellar, anterior inferior cerebellar, vertebral, and posterior inferior cerebellar arteries). Conclusion. The present contribution is intended as strictly anatomic study in which we highlighted some specific anterior and posterior circulation aneurysms that can be reached via the nose. For clinical applications of these approaches, some relevant complications, mainly related to the endonasal route, such as proximal and distal vascular control, major arterial bleeding, postoperative cerebrospinal fluid leak, and olfactory disturbances must be considered

La síndrome de Burnout en els treballadors socials a Catalunya

Aquest treball de fi de grau constitueix una proposta d’investigació sobre el fenomen del burnout o síndrome d’esgotament professional que pateixen molts treballadors socials. Concretament, es pretenen analitzar els factors causants d’aquesta síndrome així com les seves conseqüències en termes estructurals i organitzatius, de qualitat en l’atenció a les persones i personals per part dels professionals del treball social. La necessitat i interès d'abordar el tema es deu a les evidències científiques, realitzades en d’altres països, que confirmen que l'exposició als factors de risc psicosocials afecten la salut del professional i a tota l'organització. Més encara en un moment de crisi econòmica en la qual els treballadors socials han d’atendre a una major quantitat d’usuaris amb diversitat de dificultats i en situacions més complexes. En el nostre país, la investigació sobre la síndrome del burnout en l’àmbit dels treballadors socials és pràcticament inexistent, raó per la qual es fa més necessari potenciar recerques que es focalitzin en aquesta realitat.Aquest document és el resultat d’un treball continuat que comprèn tant la cerca i lectura de la bibliografia existent i rellevant sobre el fenomen del esgotament professional, com una primera fase exploratòria per contrastar el marc teòric amb la realitat catalana, concretament la de la comarca del Gironès. Posteriorment, i a partir dels resultats obtinguts, es presenta el disseny d’una investigació que ha de cobrir tot l’àmbit català. En aquest cas, s’ha optat per fer una recerca amb una metodologia qualitativa (entrevistes i grups de discussió), ja que l’objectiu és copsar les vivències, percepcions i opinions dels treballadors socials sobre les causes del burnout i les seves conseqüències. Els resultats d'aquesta investigació són considerats una oportunitat per identificar àrees de millora en l'organització de la feina i altres aspectes rellevants com el disseny del lloc de treball, les relacions interpersonals i a nivell personal

Investigació en el camp d'aprenentatge de la Noguera. Quines valoracions realitzen les escoles usuàries ?

Els Camps d’Aprenentatge són uns Serveis Educatius de la Generalitat de Catalunya distribuïts pel territori Català. Personalment penso que són poc coneguts pels docents, per això, la meva investigació tracta de conèixer la seva història i descobrir quins temes es treballen en cadascun. Principalment, investigo el Camp d’Aprenentatge de la Noguera situat en la meva població, Sant Llorenç de Montgai, per aprofundir-me en aquest i descobrir el seu funcionament. D’aquesta manera, pretenc potenciar aquests serveis educatius que utilitzen estratègies metodològiques innovadores. Pel que fa la part pràctica d’aquesta recerca, analitzo les valoracions que van realitzar els centres escolars del primer i l’últim curs, per tal d’observar l’evolució i el creixement d’aquest CdA. A més, també analitzo les observacions de la sortida realitzada amb els infants de P-5 i 1r de Primària de l’escola Dos Rius de Camarasa. Per acabar, es troben les conclusions d’aquesta investigació.
