Benthic and substrate cover data derived from a time series of photo-transect surveys for the Eastern Banks, Moreton Bay Australia, 2004-2015

This paper describes seagrass species and percentage cover point-based field data sets derived from georeferenced photo transects. Annually or biannually over a ten year period (2004-2015) data sets were collected using 30-50 transects, 500-800 m in length distributed across a 142 km**2 shallow, clear water seagrass habitat, the Eastern Banks, Moreton Bay, Australia. Each of the eight data sets include seagrass property information derived from approximately 3000 georeferenced, downward looking photographs captured at 2-4 m intervals along the transects. Photographs were manually interpreted to estimate seagrass species composition and percentage cover (Coral Point Count excel; CPCe). Understanding seagrass biology, ecology and dynamics for scientific and management purposes requires point-based data on species composition and cover. This data set, and the methods used to derive it are a globally unique example for seagrass ecological applications. It provides the basis for multiple further studies at this site, regional to global comparative studies, and, for the design of similar monitoring programs elsewhere.

Securing Medical Personnel: Case Studies of Two Source Countries and Two Destination Countries

A shortage of medical personnel has become a critical problem for developing countries attempting to expand the provision of medical services for the poor. In order to highlight the driving forces determining the international allocation of medical personnel, the cases of four countries, namely the Philippines and South Africa as source countries and Saudi Arabia and the United Kingdom as destination countries, are examined. The paper concludes that changes in demand generated in major destination countries determine the international allocation of medical personnel at least in the short run. Major destination countries often alter their policies on how many medical staff they can accept, and from where, while source countries are required to make appropriate responses to the changes in demand.

The middle-income trap from the viewpoint of trade structures

In this study, we try to elucidate the middle-income trap from the viewpoint of international trade. We conduct regression analyses on the relationship between income level and net export ratios for different types of goods for trapped and non-trapped samples separately. Our findings indicate that industrial upgrading appears to occur exactly as depicted by the flying-geese model for non-trapped countries while trapped countries tend to depend on the export of primary commodities, and industrialization appears to be driven by forward linkages to processed goods and a narrow base. The results of our analyses suggest that the middle-income trap is a form of Dutch disease or a 'resource curse' in the middle-income stage.

Innovation in Eastern Europe : a case study of Czech Republic

In this study we evaluate innovative performance of the economies of Central and Eastern Europe (CEE) based on the available statistics of innovation processes. We compare such country-level indicators as educational levels, investments in R&D, FDI, trade and licensing flows, patents and scientific articles, and find that the most developed CEE economies are also the most innovative. At the same time, as supported by the results of the interviews in Czech Republic, one of the top performers in the CEE region, its economy is facing a number of challenges that are similar to other middle-income countries around the world. We suggest addressing these challenges from the prospective of the Middle Income Trap, when a middle-income economy to sustain growth must learn to compete with advanced economies in high-skill innovation. Development of effective innovation policy should be a priority for the CEE countries to escape from the middle income trap.

An empirical mixed model to quantify climate influence on the growth of Pinus halepensis Mill. stands in South-Eastern Spain

The influence of climate on forest stand composition, development and growth is undeniable. Many studies have tried to quantify the effect of climatic variables on forest growth and yield. These works become especially important because there is a need to predict the effects of climate change on the development of forest ecosystems. One of the ways of facing this problem is the inclusion of climatic variables into the classic empirical growth models. The work has a double objective: (i) to identify the indicators which best describe the effect of climate on Pinus halepensis growth and (ii) to quantify such effect in several scenarios of rainfall decrease which are likely to occur in the Mediterranean area. A growth mixed model for P. halepensis including climatic variables is presented in this work. Growth estimates are based on data from the Spanish National Forest Inventory (SNFI). The best results are obtained for the indices including rainfall, or rainfall and temperature together, with annual precipitation, precipitation effectiveness, Emberger?s index or free bioclimatic intensity standing out among them. The final model includes Emberger?s index, free bioclimatic intensity and interactions between competition and climate indices. The results obtained show that a rainfall decrease about 5% leads to a decrease in volume growth of 5.5?7.5% depending on site quality.

Participatory modelling to support decision making in water management under uncertainty: Two comparative case studies in the Guadiana river basin, Spain.

A participatory modelling process has been conducted in two areas of the Guadiana river (the upper and the middle sub-basins), in Spain, with the aim of providing support for decision making in the water management field. The area has a semi-arid climate where irrigated agriculture plays a key role in the economic development of the region and accounts for around 90% of water use. Following the guidelines of the European Water Framework Directive, we promote stakeholder involvement in water management with the aim to achieve an improved understanding of the water system and to encourage the exchange of knowledge and views between stakeholders in order to help building a shared vision of the system. At the same time, the resulting models, which integrate the different sectors and views, provide some insight of the impacts that different management options and possible future scenarios could have. The methodology is based on a Bayesian network combined with an economic model and, in the middle Guadiana sub-basin, with a crop model. The resulting integrated modelling framework is used to simulate possible water policy, market and climate scenarios to find out the impacts of those scenarios on farm income and on the environment. At the end of the modelling process, an evaluation questionnaire was filled by participants in both sub-basins. Results show that this type of processes are found very helpful by stakeholders to improve the system understanding, to understand each others views and to reduce conflict when it exists. In addition, they found the model an extremely useful tool to support management. The graphical interface, the quantitative output and the explicit representation of uncertainty helped stakeholders to better understand the implications of the scenario tested. Finally, the combination of different types of models was also found very useful, as it allowed exploring in detail specific aspects of the water management problems.

La habitación subterránea en la Península Ibérica : investigación geológica

La habitación rupestre en la Península Ibérica conforma un amplio conjunto de manifestaciones cuyos orígenes son difíciles de dilucidar. Existen conjuntos primitivos, posiblemente horadados durante la Antigüedad Clásica y Tardía, y otros que probablemente se originaron y excavaron en la Alta Edad Media, en los que se mezclan grupos de origen religioso y otros de probable uso defensivo. El conjunto peninsular es sin duda el más variado de Europa Occidental, pues recibió influencias árabes y usos de la cristiandad antigua, importados de Oriente Próximo, que por tanto relacionan estas manifestaciones con otras del arco mediterráneo. La supervivencia del uso de las cuevas a lo largo de la Baja Edad Media -una vez afianzada la Reconquista- es una incógnita, pero los usos rupestres volvieron a generalizarse en ciertos sectores de la Península durante la Edad Moderna, toda vez que el hábitat cuevero manifestó una eclosión relacionada con la peripecia de los moriscos, primero desterrados de sus habitaciones en el Sur y Este peninsular y luego expulsados en los albores del siglo XVII. Los que quedaron, nominalmente conversos, debieron habitar de nuevo cuevas en sus lugares de origen. Esos núcleos son los más abundantes, particularmente en la provincia de Granada y aledañas. Este substrato fue seguramente el punto de apoyo para la proliferación de las cuevas de habitación a partir del siglo XIX, en el cual un creciente proletariado agrícola y urbano necesitó de alojamientos baratos y no hizo sino imitar usos preexistentes, que se pueden rastrear en muchos de los núcleos rupestres que sobrevivieron mayoritariamente hasta bien entrado el siglo XX, y que se abandonaron gradualmente a partir de los años 60 de esa centuria. Para entonces, existían barrios de cuevas extensos en muchas provincias, destacando, aparte de las andaluzas, ciertas zonas de la Cuenca del Ebro (aragonesa, navarra y riojana), del arco periurbano de Valencia, del Sur de Madrid, de la Mancha toledana, o de las provincias de Albacete, Guadalajara, Murcia e incluso de Palencia. Los núcleos antiguos se excavaron -en razón de su origen dedicado a defensa y refugio- en lugares poco accesibles, que mayoritariamente se dan en relieves anfractuosos, en las orlas marginales detríticas y carbonatadas de las cuencas terciarias y en terrenos más antiguos de la geológicamente denominada Cuenca Vasco Cantábrica, en las cuales florecieron centros de eremitismo del primitivo condado de Castilla. También son lugares inaccesibles los riscos asomados a cantiles fluviales, cuya regularización morfológica natural ha sido causa de la ruina de múltiples hipogeos que se labraron con las mismas intenciones de refugio, defensa o retiro espiritual. Los núcleos modernos se han excavado ya en terrenos más propicios (los que componen las cuencas terciarias o "España arcillosa", mayoritariamente), y por ello observamos cómo abundan las litologías sedimentarias, que son aquellas en las que se horadaron casi todas las "colmenas" de habitación moderna en la Península. En unos casos y otros, existen rasgos comunes en lo relativo a la litología y comportamiento de los materiales excavados, y también en lo relativo a su evolución, meteorización y conservación. Se han estudiado por ello estas pautas comunes -como un posible avance para el establecimiento futuro de estudios de geoconservación del patrimonio rupestre habitado-, que se traducen en la determinación de los procesos de meteorización más característicos en los antros de la Península Ibérica -sean modernos o antiguos- y en la determinación de las relaciones más habituales entre geomorfología y tipología de las cuevas de habitación. También se exponen algunas conclusiones relativas a la resistencia de los tipos pétreos en relación a la antigüedad de los emplazamientos. Esta relación se explica bien si tenemos en cuenta que las cuevas antiguas trataban de ser lugares apartados en los que dominan rocas más resistentes -como se ha explicado- y que en las modernas se ha buscado la habitación permanente, en los materiales más blandos ocupan las depresiones terciarias del Centro, Este y Sur de la Península, colonizados no ya como refugios sino de modo seguro, y ya en arrabales "extramuros" de las ciudades. Geomorfológicamente, esta razón histórica tiene consecuencias sobre la posición de las cuevas, sobre su organización, y sobre su conservación. La extensión del dominio estudiado obliga prácticamente a bosquejar algunas de estas conclusiones geológicas, pero permite a su vez proporcionar una visión global acerca del patrimonio troglodítico desde una perspectiva geológica, y en ello radica la principal novedad de la investigación. Cave dwelling in the Iberian Peninsula comprises a great deal of examples whose origins are sometimes difficult to elucidate. There are primitive groups of caves, probably belonging to Classical and Late Antiquity, and other settlements that appear to have been created and excavated in the Early Middle Ages. Some of them are due to religious reasons and some others may probably have served for defensive uses. The Peninsular group is very likely the most diverse in Western Europe, for it was not only influenced by Arabs, but it also assimilated uses from the Antique Christendom, imported from the Middle East. In this sense, Iberian cave dwellings connect with those of the Mediterranean area. There is not total certainty about the survival of caves serving for dwelling throughout the Late Middle Ages, once the Reconquista was a fact. However, underground excavations for human habitation were once again dispread in certain zones of the Peninsula during the Early Modern period. This growth of underground habitats appears in connexion with Morisco’s vicissitudes; first of all, their removal from their settlements in South and Eastern Peninsula, and finally their expulsion from Spanish territory at the very beginning of XVII th century. Those of them who rested in Spain –and that were nominally “converts”- seem to have returned to cave dwelling in their places of origin, particularly in the province of Granada and its neighbouring zones. This substrate may have been the toehold for a new spreading of cave dwellings since XIX th century, when the increasing rural and urban proletariat returned to the pre-existent uses of caves in order to solve the necessity of affordable housing. This fact can still be detected in many of the rock settlements that have survived during a great part of the XX th century and which were gradually abandoned from the 60´s onwards. There were important cave dwelling districts in many Spanish territories by that time, and not only in Andalusia. We also find them in certain areas of the Ebro basin (those of Aragon, Navarra and La Rioja), in the peri-urban arc of Valencia, in the South of Madrid province and also in the provinces of Toledo (the so called “Mancha toledana”), Albacete, Guadalajara, Murcia or even Palencia as well. Due to their defensive and refuge uses, primitive underground habitats were dug in hardly accessible places. The majority of them are located in mountainous and rough areas, when not in the marginal borders of Tertiary basins, where coarse detritic and carbonate formations outcrop. Cave dwellings can also be found in more ancient rock masses, such as those of the Basque Cantabrian Mesozoic Basin, which is the area where hermit centres of the primitive County of Castile first flourished. Cliffs surrounding fluvial valleys are as well inaccessible places, but here we find that geological evolution has caused the destruction of many rock sanctuaries and cliff dwellings that were originally dug with the same purposes of defence, refuge and spiritual retreat. Later modern cave settlements were dug in quite more favourable terrains, mainly in the soils that compose the Tertiary basins, generally known as “España arcillosa” or “Clayey Spain”. Therefore, we find abundant sedimentary fine and medium grained lithologies, which are the ones that have hosted the majority of Modern Era warren cave dwellings in the Iberian Peninsula. Actually, both types of cave dwelling share some standards regarding the lithology of the excavated materials, and they share as well certain patterns that affect to their evolution, weathering and preservation. These common patterns have been studied here in order to determine the most characteristic weathering processes that affect the majority of the Iberian caves, both Antique and Modern. And also with a view to establish the most habitual relationships between geomorphology and typology of cave dwellings. The study may as well provide a first basis for future studies on geo-preservation of cave dwellings heritage. We also reach some conclusions about the strength of different rocks concerning the antiquity of the sites. As we have already pointed out, this relation comes from the fact that ancient caves were placed in remote or isolated locations, where harder rocks outcrop, while more modern ones result from people´s search of permanent dwelling. In this sense, the softer rocks of the Tertiary Basins of Middle, East and South Peninsula provided a secure colonization to this second and modern group. And moreover, considering geomorphological features, this historical reason has had an effect not only on the position and location of the caves, but also on their organisation/structure/distribution and preservation. The huge extension of our domain of interest almost forces to sketch out some of these geological conclusions. But at the same time it gives a global panorama of Spanish troglodyte heritage, seen from a geological perspective. And here is the main novelty of this research.

Técnicas y materiales de la construcción fortificada altomedieval en el centro de la Península Ibérica: métodos de análisis a través de la arqueología y la historia de la construcción

Esta tesis doctoral tiene como objeto el acercamiento histórico-constructivo a la realidad material de las fortificaciones edificadas en el centro de la Península Ibérica durante los primeros siglos de la Edad Media. El marco geográfico se extiende desde el cauce del río Duero, delimitado por los valles de sus afluentes, el Duratón, al oeste, y el Escalote al este, hasta las cumbres del Sistema Central oriental en su entronque con el Ibérico, para descender por la falda sur de la sierra hasta los valles altos del Lozoya, Jarama y Henares. Siguiendo las demarcaciones actuales, el marco de estudio ocupa parcialmente las provincias de Soria, Guadalajara, Madrid, Segovia, Burgos y Valladolid. Desde un punto de vista cronológico, el espacio temporal se inicia con la conquista musulmana de la Península Ibérica de 711 y culmina con la incorporación definitiva al reino de Castilla de las zonas estudiadas, en torno al año 1150. Se trata de un espacio de transición, tanto desde el punto de vista social como ecológico. Los territorios al sur de la sierra correspondían a los confines septentrionales de la Marca Media de al-Andalus, mientras que la falta norte, los extrema durii, fueron un territorio escasamente poblado y desorganizado, foco de la expansión de los reinos de León y Castilla y zona de conflicto con al-Andalus a principios del siglo X. Un territorio tan amplio y heterogéneo, unido a una compleja evolución histórica y social y la parquedad de las fuentes escritas, ha necesitado de un acercamiento con una metodología de tipo mixto, en la que han convergido las técnicas propias de la documentación histórica, de la arqueología y de la historia de la construcción. Esta metodología parte de un exhaustivo vaciado bibliográfico, tras lo cual se planteó una prospección arqueológica dirigida que permitió realizar un catálogo de elementos fortificados en el área de estudio susceptibles de contener fases altomedievales. Sobre cada uno de los elementos localizados se realizó una toma de datos de tipo gráfico métrico y constructivo. Cruzando los datos recabados en cada edificio con técnicas propias de la estratigrafía e historia de la construcción se identificaron y aislaron las fases de la cronología analizada. Entre las fortificaciones que evidenciaron fases altomedievales y atendiendo a su singularidad, representatividad y calidad estratigráfica se ha profundizado en el análisis de nueve casos de estudio: el conjunto fortificado de Atienza, el castillo de Cogolludo, el recinto amurallado de Buitrago de Lozoya, el castillo de Caracena, la iglesia parroquial de la Inmaculada Concepción de Mezquetillas, la alcazaba de Gormaz, la torre de San Andrés de Sepúlveda, la iglesia parroquial de San Miguel de Ayllón y la fortificación rupestre de Alcolea de las Peñas. La investigación ha servido para dos fines principales. El primero se centra en el aspecto material. En este sentido no solo se ha identificado la presencia o ausencia de fases altomedievales en cado uno de los edificio lo que ha permitido realizar una lectura territorial, la caracterización de las diferentes técnicas y materiales constructivos y valorar la posibilidad de establecer una cronotipología. El segundo se centra en aspectos históricos y sociales. La vinculación de estos restos materiales con la documentación histórica ha devenido en un medio para conocer la historia de las gentes que construyeron estos edificios, la motivación que les llevó a emprender tales proyectos, así como el contexto en el que cada una de estas fortificaciones desempeñó las funciones para las que fue creada. Este estudio ha puesto de manifiesto la ruptura que supuso la ocupación estatal de esta zona por parte del ejército cordobés desde mediados del siglo X, tanto desde el punto de vista social como constructivo. Se ha podido documentar materialmente esta ocupación tras la restauración de Medinaceli, en torno a 946, y la sucedida tras la toma de Sepúlveda por parte de Almanzor en 984, diferenciándose claramente las técnicas constructivas propias de este momento, ejecutadas directamente por talleres foráneos, procedentes de Córdoba y Toledo. La posición estratigráfica de estas fábricas diagnósticas ha permito identificar fases constructivas inmediatamente anteriores y posteriores a este momento. También se ha podido comprobar la hipótesis inicial en relación a la pérdida de conocimientos constructivos durante el final de la Antigüedad y los primeros siglos del medievo en la zona estudiada. La sillería y la explotación de canteras, así como el ciclo productivo del ladrillo por completo, son recuperados sin recurrir a un sustrato tecnológico local, propiciados de manera efímera por la ocupación califal. Cuando se produce el desmembramiento del califato a partir del año 1010 estas técnicas se vuelven a abandonar. A finales del siglo XI y principios del siglo XII se produce un nuevo cambio en la construcción, recuperándose de nuevo estas técnicas de la mano del románico y del establecimiento de la red parroquial diocesana. En una zona y periodo histórico apenas explotado por la investigación, esta tesis doctoral busca no solo establecer una metodología de trabajo sino sentar las bases para futuros estudios, tanto desde el punto de vista particular, profundizando en el estudio constructivo y estratigráfico de cada uno de los elementos recogidos, como en otros aspectos más trasversales. ABSTRACT This doctoral thesis has a constructive historical material approach to the reality of the fortifications built in the center of the Iberian Peninsula during the first centuries of the middle Ages. The geographical framework extends from the Duero´s riverbed, bounded by the valleys of its tributaries, the Duratón on the west, and the Escalote on the east, until to the peaks of the eastern Central System at its connection with the Iberian, to descend the hillside of the mountain range to the high valleys of Lozoya, Jarama and Henares. Following the current demarcations under this framework study, partially cover the provinces of Soria, Guadalajara, Madrid, Segovia, Burgos and Valladolid. From a chronological point of view, the temporal space began with the Muslim conquest of the Iberian Peninsula in 711 A.D and ends with the final incorporation into the Kingdom of Castile in the studied areas, around the year 1150 A.D. It is a transitional gathering point, both socially and ecologically. The southern territories of the Sierra or mountain range corresponded to the northern boundaries of the Middle mark of al- Andalus , while the northern missing, the extrema Durii , were a disorganized sparsely populated territory and point of the expansion of the kingdoms of Leon and Castile and zone of conflict with al- Andalus at the beginning of the tenth century. Such a wide and diverse territory, connected with a complex historical, social evolution and the lack of written sources , has required an approach with a mixed type methodology, which have converged the techniques of historical documentation of the archeology and building history. This methodology comes from a comprehensive bibliographic study, after which an archaeological survey was directed that allowed building a fortified elements ‘catalog in the study area likely to contain high medieval period phases were raised. On each of the elements located one metric data collection and constructive graphic type was performed. Checking against the data collected in each building with its own history of stratigraphy and construction techniques and finally, they were identified and isolated the timing analysis phases. Among the early medieval fortifications that showed high period Medieval phases and according to its uniqueness , representativeness and stratigraphy’s quality of the nine case studies : the fortified complex of Atienza, Cogolludo Castle, the Buitrago de Lozoya´s walled enclosure , the Caracena´s castle , the Mezquetillas´ parish church, the Gormaz´s fortress, the San Andres toser in Sepulveda, the church of San Miguel de Ayllón and the Alcolea de las Peñas´ rock fortress. This research study has served two main purposes. The first focuses on the material side. In this sense it does not only identified the presence or absence of early medieval period phases in each one of the building, which has allowed a territorial reading and the characterization of the different construction techniques and materials, but it also assess the possibility of establishing a chrono–typology. The second focuses on historical and social aspects. The bound of these materials remains with the historical documentation has become a means to know the history of the people who built these buildings, the motivation that led them to undertake such projects as well as the context in which each of these fortifications played the functions for which it was created. This study has revealed the breach that led to the state occupation of the Cordovan army in this area by since mid-tenth century, from the social point of view and also from the structural one. It has been materially document this occupation after the restoration of Medinaceli, around 946, and succeeded after taking Sepulveda by Almanzor in 984, clearly differentiating their own building techniques currently implemented directly by foreign workshops, from Cordova and Toledo. The stratigraphic position of these factories has made it possible to identify earlier and later construction phases at this time. It has also been able to verify the initial hypothesis in relation with constructive knowledge loss during late antiquity and early medieval centuries in the studied area. Also ashlar, masonries as well as the brick production is recovered without resorting to a local technological substrate, fleetingly brought about by the Caliphate occupation. When the dismemberment of the Caliphate is produced from the year 1010 these techniques were abandoned again. In the late eleventh and early twelfth century these techniques are recovered from Romanesque and a new change came, also from the establishment of the diocesan parish network. In one historical period that has been hardly exploited by research, this thesis seeks not only to establish a working methodology but lay the groundwork for future studies, both from the particular point of view, paying special attention in the constructive and stratigraphic studies of each of the evidence collected , and additionally in other more transversal aspects.

Luz industrial e imagen tecnificada: de Moholy Nagy al C.A.V.S. (Center for Advanced Visual Studies)

El desarrollo de la tecnología de la luz implicará la transformación de la vida social, cultural y económica. Tanto las consideraciones espaciales del Movimiento Moderno, como los efectos producidos por la segunda Guerra Mundial, tendrán efectos visibles en las nuevas configuraciones espaciales y en la relación simbiótica y recíproca que se dará entre ideología y tecnología. La transformación en la comprensión de la articulación espacial, asociada al desarrollo tecnológico, afectará al modo en que este espacio es experimentado y percibido. El espacio expositivo y el espacio escénico se convertirán en laboratorio práctico donde desarrollar y hacer comprensible todo el potencial ilusorio de la luz, la proyección y la imagen, como parámetros modificadores y dinamizadores del espacio arquitectónico. Esta experimentación espacial estará precedida por la investigación y creación conceptual en el mundo plástico, donde los nuevos medios mecánicos serán responsables de la construcción de una nueva mirada moderna mediatizada por los elementos técnicos. La experimentación óptica, a través de la fotografía, el cine, o el movimiento de la luz y su percepción, vinculada a nuevos modos de representación y comunicación, se convertirá en elemento fundamental en la configuración espacial. Este ámbito de experimentación se hará patente en la Escuela de la Bauhaus, de la mano de Gropius, Schlemmer o Moholy Nagy entre otros; tanto en reflexiones teóricas como en el desarrollo de proyectos expositivos, arquitectónicos o teatrales, que evolucionarán en base a la tecnología y la modificación de la relación con el espectador. El espacio expositivo y el espacio escénico se tomarán como oportunidad de investigación espacial y de análisis de los modos de percepción, convirtiéndose en lugares de experimentación básicos para el aprendizaje. El teatro se postula como punto de encuentro entre el arte y la técnica, cobrando especial importancia la intersección con otras disciplinas en la definición espacial. Las múltiples innovaciones técnicas ligadas a los nuevos fundamentos teatrales en la modificación de la relación con la escena, que se producen a principios del siglo XX, tendrán como consecuencia la transformación del espacio en un espacio dinámico, tanto física como perceptivamente, que dará lugar a nuevas concepciones espaciales, muchas de ellas utópicas. La luz, la proyección y la creación de ilusión en base a estímulos visuales y sonoros, aparecen como elementos proyectuales efímeros e inmateriales, que tendrán una gran incidencia en el espacio y su modo de ser experimentado. La implicación de la tecnología en el arte conllevará modificaciones en la visualización, así como en la configuración espacial de los espacios destinados a esta. Destacaremos como propuesta el Teatro Total de Walter Gropius, en cuyo desarrollo se recogen de algún modo las experiencias espaciales y las investigaciones desarrolladas sobre la estructura formal de la percepción realizadas por Moholy Nagy, además de los conceptos acerca del espacio escénico desarrollados en el taller de Teatro de la Bauhaus por Oskar Schlemmer. En el Teatro Total, Gropius incorporará su propia visión de cuestiones que pertenecen a la tradición de la arquitectura teatral y las innovaciones conceptuales que estaban teniendo lugar desde finales del s.XIX, tales como la participación activa del público o la superación entre escena y auditorio, estableciendo en el proyecto una nueva relación perceptual entre sala, espectáculo y espectador; aumentando la sensación de inmersión, a través del uso de la física, la óptica, y la acústica, creando una energía concéntrica capaz de extenderse en todas direcciones. El Teatro Total será uno de los primeros ejemplos en los que desde el punto de partida del proyecto, se conjuga la imagen como elemento comunicativo con la configuración espacial. Las nuevas configuraciones escénicas tendrán como premisa de desarrollo la capacidad de transformación tanto perceptiva, como física. En la segunda mitad del s.XX, la creación de centros de investigación como el CAVS (The Center for Advanced Visual Studies,1967), o el EAT (Experiments in Art and Technology, 1966), favorecerán la colaboración interdisciplinar entre arte y ciencia, implicando a empresas de carácter tecnológico, como Siemens, HP, IBM o Philips, facilitando soporte técnico y económico para el desarrollo de nuevos sistemas. Esta colaboración interdisciplinar dará lugar a una serie de intervenciones espaciales que tendrán su mayor visibilidad en algunas Exposiciones Universales. El resultado será, en la mayoría de los casos, la creación de espacios de carácter inmersivo, donde se establecerá una relación simbiótica entre espacio, imagen, sonido, y espectador. La colocación del espectador en el centro de la escena y la disposición dinámica de imagen y sonido, crearán una particular narrativa espacial no lineal, concebida para la experiencia. Desde las primeras proyecciones de cine a la pantalla múltiple de los Eames, las técnicas espaciales de difusión del sonido en Stockhausen, o los experimentos con el movimiento físico interactivo, la imagen, la luz en movimiento y el sonido, quedan inevitablemente convertidos en material arquitectónico. ABSTRACT. Light technology development would lead to a social, cultural and economic transformation. Both spatial consideration of “Modern Movement” and Second World War effects on technology, would have a visible aftereffect on spatial configuration and on the symbiotic and mutual relationship between ideology & technology. Comprehension adjustment on the articulation of space together with technology development, would impact on how space is perceived and felt. Exhibition space and scenic space would turn into a laboratory where developing and making comprehensive all illusory potential of light, projection and image. These new parameters would modify and revitalize the architectonic space. as modifying and revitalizing parameters of architectonic space. Spatial experimentation would be preceded by conceptual creation and investigation on the sculptural field, where new mechanic media would be responsible for a fresh and modern look influenced by technical elements. Optical experimentation, through photography, cinema or light movement and its perception, would turn into essential components for spatial arrangement linked to new ways of performance and communication. This experimentation sphere would be clear at The Bauhaus School, by the hand of Gropius, Schlemmer or Moholy Nag among others; in theoretical, theatrical or architectural performance’s projects, that would evolve based on technology and also based on the transformation of the relationship with the observer. Exhibition and perfor-mance areas would be taken as opportunities of spatial investigation and for the analysis of the different ways of perception, thus becoming key places for learning. Theater is postulated as a meeting point between art and technique, taking on a new significance at its intersection with other disciplines working with spatial definition too. The multiple innovation techniques linked to the new foundations for the theater regarding stage relation, would have as a consequence the regeneration of the space. Space would turn dynamic, both physically and perceptibly, bringing innovative spatial conceptions, many of them unrealistic. Light, projection and illusory creation based on sound and visual stimulus would appear as intangible and momentary design components, which would have a great impact on the space and on the way it is experienced. Implication of technology in art would bring changes on the observer as well as on the spatial configuration of the art spaces2. It would stand out as a proposal Walter Groupis Total Theater, whose development would include somehow the spatial experiments and studies about formal structure of perception accomplished by Moholy Nagy besides the concepts regarding stage space enhanced at the Bauhaus Theater Studio by Oskar Schlemmer. Within Total Theater, Groupis would incorporate his own view about traditional theatric architecture and conceptual innovations that were taking place since the end of the nineteenth century, such as active audience participation or the diffusing limits between scene and audience, establishing a new perception relationship between auditorium, performance and audience, improving the feeling of immersion through the use of physics, optics and acoustics, creating a concentric energy capable of spreading in all directions. Total Theater would be one of the first example in which, from the beginning of the Project, image is combined as a communicating element with the spatial configuration. As a premise of development, new stage arrangement would have the capacity of transformation, both perceptive and physically. During the second half or the twentieth century, the creation of investigation centers such as CAVS (Center for Advanced Visual Studies, 1967) or EAT (Experiments in Art and Technology, 1966), would help to the interdisciplinary collaboration between art and science, involving technology companies like Siemens, HP, IBM or Philips, providing technical and economic support to the development of new systems. This interdisciplinary collaboration would give room to a series of spatial interventions which would have visibility in some Universal Exhibitions. The result would be, in most cases, the creation of immersive character spaces, where a symbiotic relationship would be stablished between space, image, sound and audience. The new location of the audience in the middle of the display, together with the dynamic arrangement of sound and image would create a particular, no lineal narrative conceived to be experienced. Since the first cinema projections, the multiple screen of Eames, the spatial techniques for sound dissemination at Stockhausen or the interactive physical movement experimentation, image, motion light and sound would turn inevitably into architectural material.

Neuroimaging studies of word reading

This review discusses how neuroimaging can contribute to our understanding of a fundamental aspect of skilled reading: the ability to pronounce a visually presented word. One contribution of neuroimaging is that it provides a tool for localizing brain regions that are active during word reading. To assess the extent to which similar results are obtained across studies, a quantitative review of nine neuroimaging investigations of word reading was conducted. Across these studies, the results converge to reveal a set of areas active during word reading, including left-lateralized regions in occipital and occipitotemporal cortex, the left frontal operculum, bilateral regions within the cerebellum, primary motor cortex, and the superior and middle temporal cortex, and medial regions in the supplementary motor area and anterior cingulate. Beyond localization, the challenge is to use neuroimaging as a tool for understanding how reading is accomplished. Central to this challenge will be the integration of neuroimaging results with information from other methodologies. To illustrate this point, this review will highlight the importance of spelling-to-sound consistency in the transformation from orthographic (word form) to phonological (word sound) representations, and then explore results from three neuroimaging studies in which the spelling-to-sound consistency of the stimuli was deliberately varied. Emphasis is placed on the pattern of activation observed within the left frontal cortex, because the results provide an example of the issues and benefits involved in relating neuroimaging results to behavioral results in normal and brain damaged subjects, and to theoretical models of reading.
