Late Miocene to Holocene calcareous nannofossils from ODP sites of Leg 125

During Leg 125 of the Ocean Drilling Program, nine sites were drilled in the Mariana and Izu-Bonin areas. The sediments recovered range in age from early Pliocene to late Pleistocene in the Mariana Region and from middle Eocene to late Pleistocene in the Izu-Bonin region. This contribution concerns the biostratigraphic study of the latest Miocene (CN9b Subzone) to late Pleistocene interval. Aquantitative analysis of all calcareous nannofossil associations was conducted for the interval encompassing late Miocene to the top of the early Pliocene. Moreover, the genera Discoaster, Amaurolithus, and Ceratolithus were quantitatively investigated from the late Miocene to late Pliocene interval. Some bioevents were identified, and variations in the composition of assemblages were linked to climatic changes.

Early Cretaceous palynomorphes from ODP Hole 113-692B

Detailed descriptions of in situ ?Valanginian to Albian Antarctic palynofloras are presented from Weddell Sea claystones with high percentages of organic matter ("black shales") and intercalated volcanic ash layers. The claystones were recovered from two sites (ODP Leg 113, Sites 692 and 693) on the continental margin of Dronning Maud Land. Palynological investigations of these Cretaceous sediments revealed a ?Valanginian-Hauterivian age for the Site 692 sediments and an Aptian-Albian age for Site 693. This paper is focused on the palynomorphs of Site 692. Miospores, dinoflagellate cysts, and acritarchs are listed and compared with early Cretaceous microfloras from the Antarctic Peninsula, Australia, and South America. The dinocyst assemblage of Site 692 seems to be very similar in composition to an assemblage from the South Shetlands (?Valanginian-Hauterivian-Barremian). It also agrees well with associations described from early Early Cretaceous sequences from the Perth Basin, southwestern Australia. According to the Australian miospore zonation schemes, the sporomorph flora from Site 692 belongs to the South Australian Foraminisporis wonthaggiensis Zone (early Valanginian to Hauterivian) or the lower part of the dinocyst Muderongia Superzone (Valanginian to Hauterivian).

Paleogene and early Neogene stable isotope record of foraminifera from ODP Leg 119 samples

Oxygen and carbon isotopic records of monogeneric and monospecific benthic and planktonic foraminifer samples from Sites 744 and 738 drilled on the southern end of the Kerguelen Plateau during ODP Leg 119 reveal the evolution of polar Indian Ocean water masses from the early Paleocene to the middle Miocene. Results from Site 738 are from sediments of early Paleocene to late Eocene age and those from Site 744 are late Eocene to middle Miocene. They suggest that intermediate waters at this location did not originate in the high latitudes during the early Eocene. Surface and near-surface waters cooled gradually after the maximum warming at 56 Ma, when surface waters were about 18°C. Intermediate waters cooled after 52 Ma. The highest temperatures (lowest d18O values) of the Cenozoic occurred from 56 to 52 Ma. The records of equatorial Pacific Site 577 and Weddell Sea Site 690 resemble that of the polar Indian Ocean in this interval. The well-documented d13C excursions toward positive values in the late Paleocene and negative values in the early Eocene are represented by foraminifers increases of 1.5 per mil and following decreases of about 3 per mil. Most of the cooling in the Paleogene occurred in the middle and late Eocene. A 2°C decrease of surface water at about 38.4 Ma heralded the beginning of extensive glacial conditions in Antarctica in the early Oligocene. At Site 744, the global d18O shift just above the Eocene/Oligocene boundary is 1.15 per mil, and occurred gradually in sediments dated at 36.5-35.9 Ma. Ice-rafted debris was deposited beginning at 36.1 Ma for about the next 2 m.y. This simultaneous occurrence of the global d18O shift with ice-rafted debris is evidence for early Oligocene glaciation in East Antarctica. Moreover, early and late Oligocene Cibicidoides d18O values between 2 and 2.2 per mil indicate intermediate water cooling and a small ice-volume effect. Production of cold dense bottom water in Antarctica was intensified with continental cooling and glaciation in the early Oligocene. Comparison of Oligocene and early Miocene isotopic data from high-latitude and low-latitude deepsea sites indicates that there were probably at least two sources of bottom waters at this time.

Sr/Ca ratios and oxygen isotopes from sclerosponges

We investigate aragonitic skeletons of the Caribbean sclerosponge Ceratoporella nicholsoni from Jamaica, 20 m below sea level (mbsl), and Pedro Bank, 125 mbsl. We use d18O and Sr/Ca ratios as temperature proxies to reconstruct the Caribbean mixed layer and thermocline temperature history since 1400 A.D. with a decadal time resolution. Our age models are based on U/Th dating and locating of the radiocarbon bomb spike. The modern temperature difference between the two sites is used to tentatively calibrate the C. nicholsoni Sr/Ca thermometer. The resulting calibration points to a temperature sensitivity of Sr/Ca in C. nicholsoni aragonite of about -0.1 mmol/mol/K. Our Sr/Ca records reveal a pronounced warming from the early 19th to the late 20th century, both at 20 and 125 mbsl. Two temperature minima in the shallow water record during the late 17th and early 19th century correspond to the Maunder and Dalton sunspot minima, respectively. Another major cooling occurred in the late 16th century and is not correlatable with a sunspot minimum. The temperature contrast between the two sites decreased from the 14th century to a minimum in the late 17th century and subsequently increased to modern values in the early 19th century. This is interpreted as a long-term deepening and subsequent shoaling of the Caribbean thermocline. The major trends of the Sr/Ca records are reproduced in both specimens but hardly reflected in the d18O records.

Geochemistry and accumulation rates of the early Paleogene in the Weddel Sea, Maud Rise and Kerguelen Plateau

Marine biological productivity has been invoked as a possible climate driver during the early Paleogene through its potential influence on atmospheric carbon dioxide concentrations. However, the relationship of export productivity (the flux of organic carbon (C) from the surface ocean to the deep ocean) to organic C burial flux (the flux of organic C from the deep ocean that is buried in marine sediments) is not well understood. We examine the various components involved with atmosphere-to-ocean C transfer by reconstructing early Paleogene carbonate and silica production (using carbonate and silica mass accumulation rates (MARs)); export productivity (using biogenic barium (bio-Ba) MARs); organic C burial flux (using reactive phosphorus (P) MARs); redox conditions (using uranium and manganese contents); and the fraction of organic C buried relative to export productivity (using reactive P to bio-Ba ratios). Our investigations concentrate on Paleocene/Eocene sections of Sites 689/690 from Maud Rise and Site 738 from Kerguelen Plateau. In both regions, export productivity, organic C burial flux, and the fraction of organic C buried relative to export productivity decreased from the Paleocene/early Eocene to the middle Eocene. A shift is indicated from an early Paleogene two-gyre circulation in which nutrients were not efficiently recycled to the surface via upwelling in these regions, to a circulation more like the present day with efficient recycling of nutrients to the surface ocean. Export productivity was enhanced for Kerguelen Plateau relative to Maud Rise throughout the early Paleogene, possibly due to internal waves generated by the plateau regardless of gyre circulation.

Middle Eocene-Early Pliocene Subantarctic planktic foraminiferal biostratigraphy of ODP Site 1090 on the Agulhas Ridge, South Atlantic

The analysis of planktic foraminiferal assemblages from Site 1090 (ODP Leg 177), located in the central part of the Subantarctic Zone south of South Africa, provided a geochronology of a 330-m-thick sequence spanning the Middle Eocene to Early Pliocene. A sequence of discrete bioevents enables the calibration of the Antarctic Paleogene (AP) Zonation with lower latitude biozonal schemes for the Middle-Late Eocene interval. In spite of the poor recovery of planktic foraminiferal assemblages, a correlation with the lower latitude standard planktic foraminiferal zonations has been attempted for the whole surveyed interval. Identified bioevents have been tentatively calibrated to the geomagnetic polarity time scale following the biochronology of Berggren et al. (1995). Besides planktic foraminiferal bioevents, the disappearance of the benthic foraminifera Nuttallides truempyi has been used to approximate the Middle/Late Eocene boundary. A hiatus of at least 11.7 Myr occurs between V78 and V71 m composite depth extending from the Early Miocene to the latest Miocene-Early Pliocene. Middle Eocene assemblages exhibit a temperate affinity, while the loss of several planktic foraminiferal species by late Middle to early Late Eocene time reflects cooling. During the Late Eocene-Oligocene intense dissolution caused impoverishment of planktic foraminiferal assemblages possibly following the emplacement of cold, corrosive bottom waters. Two warming peaks are, however, observed: the late Middle Eocene is marked by the invasion of the warmer water Acarinina spinuloinflata and Hantkenina alabamensis at 40.5 Ma, while the middle Late Eocene experienced the immigration of some globigerinathekids including Globigerinatheka luterbacheri and Globigerinatheka cf. semiinvoluta at 34.3 Ma. A more continuous record is observed for the Early Miocene and the Late Miocene-Early Pliocene where planktic foraminiferal assemblages show a distinct affinity with southern mid- to high-latitude faunas.

Auto component supply chain: a path to global India

Supply chain management works to bring the supplier, the distributor, and the customer into one cohesive process. The Supply Chain Council defined supply chain as ‘Supply Chain: The flow and transformation of raw materials into products from suppliers through production and distribution facilities to the ultimate consumer., and then Sunil Chopra and Meindl, (2001) have define Supply chain management as ‘Supply Chain Management involves the flows between and among stages in a supply chain to maximize total profitability.’ After 1950, supply chain management got a boost with the production and manufacturing sector getting highest attention. The inventory became the responsibility of the marketing, accounting and production areas. Order processing was part of accounting and sales. Supply chain management became one of the most powerful engines of business transformation. It is the one area where operational efficiency can be gained. It reduces organizations costs and enhances customer service. With the liberalization of world trade, globalization, and emergence of the new markets, many organizations have customers and competitions throughout the world, either directly or indirectly. Business communities are aware that global competitiveness is the key to the success of a business. Competitiveness is ability to produce, distribute and provide products and services for the open market in competition with others. The supply chain, a critical link between supplier, producer and customer is emerged now as an essential business process and a strategic lever, potential value contributor a differentiator for the success of any business. Supply chain management is the management of all internal and external processes or functions to satisfy a customer’s order (from raw materials through conversion and manufacture through logistics delivery.). Goods-either in raw form or processed, whole sale or retailed distribution, business or technology services, in everyday life- in the business or household- directly or indirectly supply chain is ubiquitously associated in expanding socio-economic development. Supply chain growth competitive performance and supporting strong growth impulse at micro as well as micro economic levels. Keeping the India vision at the core of the objective, the role of supply chain is to take up social economic challenges, improve competitive advantages, develop strategies, built capabilities, enhance value propositions, adapt right technology, collaborate with stakeholders and deliver environmentally sustainable outcomes with minimum resources.

Knowledge pipeline in freight pipeline industry: competence- based model for open innovation

There is growing concern over the challenges for innovation in Freight Pipeline industry. Since the early works of Chesbrough a decade ago, we have learned a lot about the content, context and process of open innovation. However, much more research is needed in Freight Pipeline Industry. The reality is that few corporations have institutionalized open innovation practices in ways that have enabled substantial growth or industry leadership. Based on this, we pursue the following question: How does a firm’s integration into knowledge networks depend on its ability to manage knowledge? A competence-based model for freight pipeline organizations is analysed, this model should be understood by any organization in order to be successful in motivating professionals who carry out innovations and play a main role in collaborative knowledge creation processes. This paper aims to explain how can open innovation achieve its potential in most Freight Pipeline Industries.

Effect of short-term fasting prior to slaughter on welfare and meat quality or rainbow trout (Oncorhynchus mykiss)

El manejo pre-sacrificio es de vital importancia en acuicultura, ya que afecta tanto a las reacciones fisiológicas como a los procesos bioquímicos post mortem, y por tanto al bienestar y a la calidad del producto. El ayuno pre-sacrificio se lleva a cabo de forma habitual en acuicultura, ya que permite el vaciado del aparato digestivo de restos de alimento y heces, reduciendo de esta manera la carga bacteriana en el intestino y la dispersión de enzimas digestivos y potenciales patógenos a la carne. Sin embargo, la duración óptima de este ayuno sin que el pez sufra un estrés innecesario no está clara. Además, se sabe muy poco sobre la mejor hora del día para realizar el sacrificio, lo que a su vez está regido por los ritmos diarios de los parámetros fisiológicos de estrés. Finalmente, se sabe que la temperatura del agua juega un papel muy importante en la fisiología del estrés pero no se ha determinado su efecto en combinación con el ayuno. Además, las actuales recomendaciones en relación a la duración óptima del ayuno previo al sacrificio en peces no suelen considerar la temperatura del agua y se basan únicamente en días y no en grados día (ºC d). Se determinó el efecto del ayuno previo al sacrificio (1, 2 y 3 días, equivalente a 11,1-68,0 grados día) y la hora de sacrificio (08h00, 14h00 y 20h00) en trucha arco iris (Oncorhynchus mykiss) de tamaño comercial en cuatro pruebas usando diferentes temperaturas de agua (Prueba 1: 11,8 ºC; Prueba 2: 19,2 ºC; Prueba 3: 11,1 ºC; y Prueba 4: 22,7 ºC). Se midieron indicadores biométricos, hematológicos, metabólicos y de calidad de la carne. En cada prueba, los valores de los animales ayunados (n=90) se compararon con 90 animales control mantenidos bajo condiciones similares pero nos ayunados. Los resultados sugieren que el ayuno tuvo un efecto significativo sobre los indicadores biométricos. El coeficiente de condición en los animales ayunados fue menor que en los controles después de 2 días de ayuno. El vaciado del aparato digestivo se produjo durante las primeras 24 h de ayuno, encontrándose pequeñas cantidades de alimento después de 48 h. Por otra parte, este vaciado fue más rápido cuando las temperaturas fueron más altas. El peso del hígado de los animales ayunados fue menor y las diferencias entre truchas ayunadas y controles fueron más evidentes a medida que el vaciado del aparato digestivo fue más rápido. El efecto del ayuno hasta 3 días en los indicadores hematológicos no fue significativo. Los niveles de cortisol en plasma resultaron ser altos tanto en truchas ayunadas como en las alimentadas en todas las pruebas realizadas. La concentración media de glucosa varió entre pruebas pero mostró una tendencia a disminuir en animales ayunados a medida que el ayuno progresaba. En cualquier caso, parece que la temperatura del agua jugó un papel muy importante, ya que se encontraron concentraciones más altas durante los días 2 y 3 de ayuno en animales mantenidos a temperaturas más bajas previamente al sacrificio. Los altos niveles de lactato obtenidos en sangre parecen sugerir episodios de intensa actividad muscular pero no se pudo encontrar relación con el ayuno. De la misma manera, el nivel de hematocrito no mostró efecto alguno del ayuno y los leucocitos tendieron a ser más altos cuando los animales estaban menos estresados y cuando su condición corporal fue mayor. Finalmente, la disminución del peso del hígado (índice hepatosomático) en la Prueba 3 no se vio acompañada de una reducción del glucógeno hepático, lo que sugiere que las truchas emplearon una estrategia diferente para mantener constantes los niveles de glucosa durante el periodo de ayuno en esa prueba. En relación a la hora de sacrificio, se obtuvieron niveles más bajos de cortisol a las 20h00, lo que indica que las truchas estaban menos estresadas y que el manejo pre-sacrificio podría resultar menos estresante por la noche. Los niveles de hematocrito fueron también más bajos a las 20h00 pero solo con temperaturas más bajas, sugiriendo que las altas temperaturas incrementan el metabolismo. Ni el ayuno ni la hora de sacrificio tuvieron un efecto significativo sobre la evolución de la calidad de la carne durante los 3 días de almacenamiento. Por el contrario, el tiempo de almacenamiento sí que parece tener un efecto claro sobre los parámetros de calidad del producto final. Los niveles más bajos de pH se alcanzaron a las 24-48 h post mortem, con una lata variabilidad entre duraciones del ayuno (1, 2 y 3 días) en animales sacrificados a las 20h00, aunque no se pudo distinguir ningún patrón común. Por otra parte, la mayor rigidez asociada al rigor mortis se produjo a las 24 h del sacrificio. La capacidad de retención de agua se mostró muy estable durante el período de almacenamiento y parece ser independiente de los cambios en el pH. El parámetro L* de color se incrementó a medida que avanzaba el período de almacenamiento de la carne, mientras que los valores a* y b* no variaron en gran medida. En conclusión, basándose en los resultados hematológicos, el sacrificio a última hora del día parece tener un efecto menos negativo en el bienestar. De manera general, nuestros resultados sugieren que la trucha arco iris puede soportar un período de ayuno previo al sacrificio de hasta 3 días o 68 ºC d sin que su bienestar se vea seriamente comprometido. Es probable que con temperaturas más bajas las truchas pudieran ser ayunadas durante más tiempo sin ningún efecto negativo sobre su bienestar. En cualquier caso, se necesitan más estudios para determinar la relación entre la temperatura del agua y la duración óptima del ayuno en términos de pérdida de peso vivo y la disminución de los niveles de glucosa en sangre y otros indicadores metabólicos. SUMMARY Pre-slaughter handling in fish is important because it affects both physiological reactions and post mortem biochemical processes, and thus welfare and product quality. Pre-slaughter fasting is regularly carried out in aquaculture, as it empties the viscera of food and faeces, thus reducing the intestinal bacteria load and the spread of gut enzymes and potential pathogens to the flesh. However, it is unclear how long rainbow trout can be fasted before suffering unnecessary stress. In addition, very little is known about the best time of the day to slaughter fish, which may in turn be dictated by diurnal rhythms in physiological stress parameters. Water temperature is also known to play a very important role in stress physiology in fish but the combined effect with fasting is unclear. Current recommendations regarding the optimal duration of pre-slaughter fasting do not normally consider water temperature and are only based on days, not degree days (ºC d). The effects of short-term fasting prior to slaughter (1, 2 and 3 days, between 11.1 and 68.0 ºC days) and hour of slaughter (08h00, 14h00 and 20h00) were determined in commercial-sized rainbow trout (Oncorhynchus mykiss) over four trials at different water temperatures (TRIAL 1, 11.8 ºC; TRIAL 2, 19.2 ºC; TRIAL 3, 11.1 ºC; and TRIAL 4, 22.7 ºC). We measured biometric, haematological, metabolic and product quality indicators. In each trial, the values of fasted fish (n=90) were compared with 90 control fish kept under similar conditions but not fasted. Results show that fasting affected biometric indicators. The coefficient of condition in fasted trout was lower than controls 2 days after food deprivation. Gut emptying occurred within the first 24 h after the cessation of feeding, with small traces of digesta after 48 h. Gut emptying was faster at higher water temperatures. Liver weight decreased in food deprived fish and differences between fasted and fed trout were more evident when gut clearance was faster. The overall effect of fasting for up to three days on haematological indicators was small. Plasma cortisol levels were high in both fasted and fed fish in all trials. Plasma glucose response to fasting varied among trials, but it tended to be lower in fasted fish as the days of fasting increased. In any case, it seems that water temperature played a more important role, with higher concentrations at lower temperatures on days 2 and 3 after the cessation of feeding. Plasma lactate levels indicate moments of high muscular activity and were also high, but no variation related to fasting could be found. Haematocrit did not show any significant effect of fasting, but leucocytes tended to be higher when trout were less stressed and when their body condition was higher. Finally, the loss of liver weight was not accompanied by a decrease in liver glycogen (only measured in TRIAL 3), suggesting that a different strategy to maintain plasma glucose levels was used. Regarding the hour of slaughter, lower cortisol levels were found at 20h00, suggesting that trout were less stressed later in the day and that pre-slaughter handling may be less stressful at night. Haematocrit levels were also lower at 20h00 but only at lower temperatures, indicating that higher temperatures increase metabolism. Neither fasting nor the hour of slaughter had a significant effect on the evolution of meat quality during 3 days of storage. In contrast, storage time seemed to have a more important effect on meat quality parameters. The lowest pH was reached 24-48 h post mortem, with a higher variability among fasting durations at 20h00, although no clear pattern could be discerned. Maximum stiffening from rigor mortis occurred after 24 h. The water holding capacity was very stable throughout storage and seemed to be independent of pH changes. Meat lightness (L*) slightly increased during storage and a* and b*-values were relatively stable. In conclusion, based on the haematological results, slaughtering at night may have less of a negative effect on welfare than at other times of the day. Overall, our results suggest that rainbow trout can cope well with fasting up to three days or 68 ºC d prior to slaughter and that their welfare is therefore not seriously compromised. At low water temperatures, trout could probably be fasted for longer periods without negative effects on welfare but more research is needed to determine the relationship between water temperature and days of fasting in terms of loss of live weight and the decrease in plasma glucose and other metabolic indicators.

Provision of ecological infrastructures to increase pollinators and other beneficial organisms in rainfed crops in Central Spain

In sustainable intensive agriculture, the biodiversity of monoculture fields can be increased by managing the field margins to provide ecological infrastructures that serve as refuges and resources for beneficial organisms (pollinators and natural enemies). In the present work we summarize two years of field trials following the goal to increase biodiversity of beneficial fauna in a barley field in Central Spain by sowing different herbaceous mixtures in the field margins. The presence of arthropods visiting flowers on plots sown with different types of seed mixtures and unsown natural flora (control plot) was compared by visual sampling every week between April and June. The results showed that a combination of herbaceous big-size seeds was the most successful mixture emerging under our experimental conditions and achieved a higher number of visits of beneficial arthropods than the unsown natural vegetation.

Identifying the semantics of eligibility criteria of clinical trials based on relevant medical ontologies

An important objective of the INTEGRATE project1 is to build tools that support the efficient execution of post-genomic multi-centric clinical trials in breast cancer, which includes the automatic assessment of the eligibility of patients for available trials. The population suited to be enrolled in a trial is described by a set of free-text eligibility criteria that are both syntactically and semantically complex. At the same time, the assessment of the eligibility of a patient for a trial requires the (machineprocessable) understanding of the semantics of the eligibility criteria in order to further evaluate if the patient data available for example in the hospital EHR satisfies these criteria. This paper presents an analysis of the semantics of the clinical trial eligibility criteria based on relevant medical ontologies in the clinical research domain: SNOMED-CT, LOINC, MedDRA. We detect subsets of these widely-adopted ontologies that characterize the semantics of the eligibility criteria of trials in various clinical domains and compare these sets. Next, we evaluate the occurrence frequency of the concepts in the concrete case of breast cancer (which is our first application domain) in order to provide meaningful priorities for the task of binding/mapping these ontology concepts to the actual patient data. We further assess the effort required to extend our approach to new domains in terms of additional semantic mappings that need to be developed.

State Convergence Theory Applied to a Delayed Teleoperation System

State convergence is a control strategy that was proposed in the early 2000s to ensure stability and transparency in a teleoperation system under specific control gains values. This control strategy has been implemented for a linear system with or without time delay. This paper represents the first attempt at demonstrating, theoretically and experimentantally, that this control strategy can also be applied to a nonlinear teleoperation system with n degrees of freedom and delay in the communication channel. It is assumed that the human operator applies a constant force on the local manipulator during the teleoperation. In addition, the interaction between the remote manipulator and the environment is considered passive. Communication between the local and remote sites is made by means of a communication channel with variable time delay. In this article the theory of Lyapunov-Krasovskii was used to demonstrate that the local-remote teleoperation system is asymptotically stable.

Idas y venidas. Los viajes de arquitectura en España entre 1920 y 1960

Esta tesis se propone indagar en las vias por las que la arquitectura española cambió en el periodo comprendido entre 1920 y 1960 y el papel que los viajes tuvieron en dicho cambio. La investigación busca demostrar que, junto a otros factores como la llegada de revistas y libros y las conferencias de arquitectos de la talla de Le Corbusier, Gropius, Mendelsohn, Neutra o Aalto, los viajes tuvieron un papel clave en el proceso de apertura de miras y que provocó que, bien a traves de lo publicado en las revistas por los “arquitectos viajeros” o por el reflejo que tuvo lo conocido fuera de nuestras fronteras en proyectos y obras concretas, un buen numero de arquitectos, que no tuvieron la posibilidad de viajar, pudieron conocer que existía una realidad muy distinta a la que los profesores en la Escuela les habían enseñado o a la que estaban acostumbrados a ver en otros arquitectos de generaciones anteriores basada, en buena medida, en la recuperación de un estilo propio nacional centrandose en los historicismos. A lo largo de la investigación trataremos de ver que efecto produjo la apertura de fronteras y que papel tuvieron los viajes en dicho proceso. También nos centraremos en comprobar hasta qué punto cambió la manera de ver la arquitectura de los protagonistas del viaje y de aquellos que recibieron la información por ellos encontrada. Veremos cómo dicha información es cuantificable, clasificable y demostrable en propuestas concretas. Será importante ver que motivó su salida, que buscaban y que encontraron así como, entre las influencias recibidas, cuales tuvieron un mayor calado: las propuestas europeas o las americanas, y dentro de las primeras, las holandesas, las alemanas o las francesas. Los objetivos que se persigue conseguir son: contribuir a un mayor conocimiento de la arquitectura entre 1920 y 1960 a través de las conexiones internacionales y el ensanchamiento de horizontes, recopilar, clasificar y analizar todo el material obtenido relacionando los viajes con las biografías de los arquitectos protagonistas, estudiar qué interesa a los arquitectos españoles cuando van fuera y porqué (será importante ver quiénes de entre los arquitectos son más abiertos a las corrientes europeas y que motivó su salida en busca de nuevos lenguajes), ordenar las reflexiones que exponen los arquitectos a la vuelta de sus viajes y ver en que propuestas y de qué forma los arquitectos plasman lo encontrado en su búsqueda en el extranjero. Para conseguir estos objetivos estructuraremos la investigación en tres bloques: En el primero de ellos nos centraremos en profundizar como era la arquitectura española a principios del siglo XX. Para poder entender mejor las transformaciones que los viajes provocaron será necesario conocer cuál era la arquitectura predominante en estos años que, como veremos, consistía en la búsqueda de un estilo nacional propio dirigiendo su mirada al pasado. También veremos cómo un grupo de arquitectos (Palacios, Flórez, Torres Balbás o Anasagasti) fueron pioneros en el deseo de mirar fuera de nuestras fronteras así como dedicaremos especial atención a cómo era la formación en la Escuela. El segundo capítulo, que abarca desde principios de los años 20 hasta la Guerra Civil, tratará de demostrar la importancia que tuvo en el proceso de permeabilidad frente a las corrientes extranjeras los viajes que los arquitectos realizaron y que, sumados a la llegada de revistas y las visitas de los principales arquitectos modernos, provocaron una primera apertura como respuesta a los historicismos predominantes. Entre los arquitectos viajeros destacaremos las figuras de Fernando García Mercadal (incidiendo en su importancia como difusor de la arquitectura moderna), Rafael Bergamín, Ramón Sánchez Arcas y Luis Lacasa. También nos detendremos en ver la importancia que tuvieron las exposiciones (con especial atención a la de Artes Decorativas de París de 1925 y la de la Deutscher Werkbund en Stuttgart en 1927) que se realizaron estos años y como llegó la información a nuestro país. El tercer y último capítulo arranca con el periodo de posguerra, una época de transición pues los viajes que se realizaron fueron escasos y en la mayoría de las ocasiones no se llevaron a cabo en busca de nuevos caminos. Veremos cómo tras la Guerra y de la mano de la dictadura se produce, de la misma forma que en la Alemania nazi, una vuelta al interés por los historicismos de principios de siglo. Para entender mejor este periodo haremos un repaso a la obra de Luis Gutiérrez Soto por ser explicativa de lo cambiante de las corrientes arquitectónicas de estos años. Tras el análisis de los sucedido en posguerra nos dedicaremos a analizar, de la misma forma que en el primer periodo, la manera en que se produjo el rechazo al estilo nacional de nuevo gracias a la llegada de libros y revistas, lo publicado por las revistas españolas, las visitas de arquitectos de prestigio así como los viajes de un grupo de arquitectos que, de manera individual, salieron al extranjero en busca de apoyo, de referencias en los que cimentar su arquitectura. De este grupo, por la importancia que los propios protagonistas dieron al hecho de viajar como complemento a su formación y por la manera en la que reflejaron lo aprendido en proyectos concretos destacamos a Francisco de Asís Cabrero, Miguel Fisac, Ramón Vázquez Molezún y Francisco Javier Sáenz de Oiza. De nuevo, igual que en el primer capítulo finalizaremos la investigación dedicando un apartado a las exposiciones (fundamentalmente la Interbau de Berlín de 1957) celebradas en estos años. Para finalizar estableceremos las conclusiones que nos llevarán a comprobar hasta qué punto la arquitectura española en los periodos previo y posterior a la guerra cambió y en qué medida tuvieron importancia los viajes que los arquitectos españoles realizaron al extranjero en dicho cambio… ABSTRACT This thesis aims to look at the ways which Spanish architecture changed in the period between 1920 and 1960, and the way it was effected by travelling . The research will demonstrate that, together with other factors, such as the arrival of magazines, books, conferences and architects like Le Corbusier, Gropius, Mendelsohn, Neutra or Aalto, travelling played a key role in architecture. Also, it changed the way we look at architecture. Travelling, thanks to the published journals by "travelling architects” and the influence that they had - known beyond our borders in projects and concrete works, caused the arrival of a new type of architects. Even those who were not able to travel, knew that there was a very different reality than the reality the teachers at the school had taught them. Also, the “new reality” was different from the one that they were used to seeing in other architects of earlier generations, based mainly on the recovery of a national style focused on historicism. Throughout the investigation I will try to show the effect that the opening of borders and travelling had on this process. We will also focus on checking how it changed the way we see the architecture, from the point of view of the protagonists of the travels and those who received the information . We will see how that information is quantifiable and demonstrably classifiable into concrete proposals. It will be important to see which led to their departure. They sought and found among the influences, which had a major impact: the proposed European or American, and within the first, Dutch, German or French. The objectives to be achieved are: To contribute to a better understanding of architecture between 1920 to 1960 by the international connections, and widening the horizon. To collect, classify and analyze all obtained materials related to travelling with biographies of architects protagonists. To study what the interests of the Spanish architects were when they went abroad and why ( it will be important to see who among those architects were more open to European trends and prompted their departures for new languages). To order reflections exhibited by architects around his travels and to see what proposals and how architects reflected what they found in their search abroad. To achieve these objectives we will structure this research in three areas: In the first one, we will focus on how the Spanish architecture in the early twentieth century was. To better understand the changes that travelling caused it is necessary to understand that the predominant architecture in these years was in pursuit of its own national style, directing its gaze to the past, like we shall see. We will also see how a group of architects (Palacios, Flórez, Torres Balbás or Anasagasti) pioneered by looking beyond our borders and devote special attention to how the training was in the School. The second chapter, ranging from early 20s to the Civil War, will try to demonstrate the importance that travelling had in the process of diffusion currents. That, together with the arrival of magazines and visits by leading modern architects, led to a first opening in architecture, in response to the prevailing historicism. Among the travelers we highlight architects like Fernando García Mercadal (stressing his importance as a disseminator of modern architecture), Rafael Bergamín, Ramón Sánchez Arcas and Luis Lacasa. We will also stop to see the importance of exhibitions (with special attention to the Decorative Arts in Paris in 1925 and the Deutscher Werkbund in Stuttgart in 1927) that were held over the years and how the information came to our country . The third and final chapter starts with the post war period, a time of transition for the travels, which were scarce and in most cases were not conducted on new roads. We will see that after the war and with the dictatorship, a return to interest in historicism of the century occurred, just as in Nazi Germany. For better understanding of this period we will review the work of Luis Gutiérrez Soto. His work is explanatory of the changing of architectural trends over these years. After analyzing the case in post war, we turn to analyze, in the same way as in the first period, the manner in which rejection occurred in national style again with the arrival of books and magazines. Visits by prestigious architects and group travels of architects who, individually, went abroad in search of support, references on which to base their architecture. In this group of architects, due to the importance that the protagonists gave to the act of traveling to improve their training and the way in which they reflected what they learned in practical projects, I include Francisco de Asís Cabrero, Miguel Fisac, Ramon Vazquez Molezún and Francisco Javier Saenz de Oiza. Again, as in the first chapter, we will conclude the investigation dedicating a section to the exhibitions held in these years (mainly Interbau Berlin, 1957). Finally establishing conclusions lead us to see how far the Spanish architecture in the pre- and post -war periods changed and how much the trips were important to Spanish architects who performed abroad on the change...

A supervised cooperative learning system for early detection of language disorders

The Quality of Life of a person may depend on early attention to his neurodevel-opment disorders in childhood. Identification of language disorders under the age of six years old can speed up required diagnosis and/or treatment processes. This paper details the enhancement of a Clinical Decision Support System (CDSS) aimed to assist pediatricians and language therapists at early identification and re-ferral of language disorders. The system helps to fine tune the Knowledge Base of Language Delays (KBLD) that was already developed and validated in clinical routine with 146 children. Medical experts supported the construction of Gades CDSS by getting scientific consensus from literature and fifteen years of regis-tered use cases of children with language disorders. The current research focuses on an innovative cooperative model that allows the evolution of the KBLD of Gades through the supervised evaluation of the CDSS learnings with experts¿ feedback. The deployment of the resulting system is being assessed under a mul-tidisciplinary team of seven experts from the fields of speech therapist, neonatol-ogy, pediatrics, and neurology.

The Use of Patents to Assess National Innovation Systems: Evidences from Spanish Biotechnology

Spain’s economy recorded a high rate of growth from the mid-1990s onwards. At the same time, the resources allocated to Research and Development (R&D) grew at a much faster pace than in other European Union (EU) countries. Spain’s growth recorded an average rate of 2.93% from the early 1990s to 2004. Over the same period, the average growth in the EU was 0.46%. This circumstance, together with several sound policy decisions implemented between 2004 and 2009, ushered in a “golden age of Spanish biotechnology”. In terms of the national patent licenses issued by the Spanish Patent and Trademark Office (SPTO) between 2004 and 2009, the number in biotechnology grew from 84 to 151. However, the current economic situation in Spain, along with a series of political decisions taken over the past two or three years to cut spending on R&D, predicts a sharp downturn in the performance of Spanish biotechnology. This scenario makes Spain one of the best places to study the successes and failures of the management of science and allows transfer this experience to the other international regions. We need to analyze the influence of political decisions as a major factor with a bearing on the quality of science. Using patents as an indicator of scientific development, this paper analyzes the evolution of the biotechnology sector in Spain and its relationship with scientific policy and the management of R&D.
