Molecular data are now widely used in epidemiological studies to investigate the transmission, distribution, biology, and diversity of pathogens. Our objective was to establish recommendations to support good scientific reporting of molecular epidemiological studies to encourage authors to consider specific threats to valid inference. The statement Strengthening the Reporting of Molecular Epidemiology for Infectious Diseases (STROME-ID) builds upon the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) initiative. The STROME-ID statement was developed by a working group of epidemiologists, statisticians, bioinformaticians, virologists, and microbiologists with expertise in control of infection and communicable diseases. The statement focuses on issues relating to the reporting of epidemiological studies of infectious diseases using molecular data that were not addressed by STROBE. STROME-ID addresses terminology, measures of genetic diversity within pathogen populations, laboratory methods, sample collection, use of molecular markers, molecular clocks, timeframe, multiple-strain infections, non-independence of infectious-disease data, missing data, ascertainment bias, consistency between molecular and epidemiological data, and ethical considerations with respect to infectious-disease research. In total, 20 items were added to the 22 item STROBE checklist. When used, the STROME-ID recommendations should advance the quality and transparency of scientific reporting, with clear benefits for evidence reviews and health-policy decision making.

We present a fully automatic segmentation method for multi-modal brain tumor segmentation. The proposed generative-discriminative hybrid model generates initial tissue probabilities, which are used subsequently for enhancing the classi�cation and spatial regularization. The model has been evaluated on the BRATS2013 training set, which includes multimodal MRI images from patients with high- and low-grade gliomas. Our method is capable of segmenting the image into healthy (GM, WM, CSF) and pathological tissue (necrotic, enhancing and non-enhancing tumor, edema). We achieved state-of-the-art performance (Dice mean values of 0.69 and 0.8 for tumor subcompartments and complete tumor respectively) within a reasonable timeframe (4 to 15 minutes).

Cells infected with MuSVts110 express a viral RNA which contains an inherent conditional defect in RNA splicing. It has been shown previously that splicing of the MuSVts110 primary transcript is essential to morphological transformation of 6m2 cells in vitro. A growth temperature of 33$\sp\circ$C is permissive for viral RNA splicing,and, consequently, 6m2 cells appear morphologically transformed at this temperature. However, 6m2 cells appear phenotypically normal when incubated at 39$\sp\circ$C, the non-permissive temperature for viral RNA splicing.^ After a shift from 39$\sp\circ$C to 33$\sp\circ$C, the coordinate splicing of previously synthesized and newly transcribed MuSVts110 RNA was achieved. By S1 nuclease analysis of total RNA isolated at various times, 5$\sp\prime$ splice site cleavage of the MuSVts110 transcript appeared to occur 60 minutes after the shift to 33$\sp\circ$C, and 30 minutes prior to detectable exon ligation. In addition, consistent with the permissive temperatures and the kinetic timeframe of viral RNA splicing after a shift to 33$\sp\circ$C, four temperature sensitive blockades to primer extension were identified 26-75 bases upstream of the 3$\sp\prime$ splice site. These blockades likely reflect four branchpoint sequences utilized in the formation of MuSVts110 lariat splicing-intermediates.^ The 54-5A4 cell line is a spontaneous revertant of 6m2 cells and appears transformed at all growth temperatures. Primer extension sequence analysis has shown that a five base deletion occurred at the 3$\sp\prime$ splice site in MuSVts110 RNA allowing the expression of a viral transforming protein in 54-5A4 in the absence of RNA splicing, whereas in the parental 6m2 cell line, a splicing event is necessary to generate a similar transforming protein. As a consequence of this deletion, splicing cannot occur and the formation of the four MuSVts110 branched-intermediates were not observed at any temperature in 54-5A4 cells. However, 5$\sp\prime$ splice site cleavage was still detected at 33$\sp\circ$C.^ Finally, we have investigated the role of the 1488 bp deletion which occurred in the generation of MuSVts110 in the activation of temperature sensitive viral RNA splicing. This deletion appears solely responsible for splice site activation. Whether intron size is the crucial factor in MuSVts110 RNA splicing or whether inhibitory sequences were removed by the deletion is currently unknown.

We examined outcomes and trends in surgery and radiation use for patients with locally advanced esophageal cancer, for whom optimal treatment isn't clear. Trends in surgery and radiation for patients with T1-T3N1M0 squamous cell or adenocarcinoma of the mid or distal esophagus in the Surveillance, Epidemiology, and End Results database from 1998 to 2008 were analyzed using generalized linear models including year as predictor; Surveillance, Epidemiology, and End Results doesn't record chemotherapy data. Local treatment was unimodal if patients had only surgery or radiation and bimodal if they had both. Five-year cancer-specific survival (CSS) and overall survival (OS) were analyzed using propensity-score adjusted Cox proportional-hazard models. Overall 5-year survival for the 3295 patients identified (mean age 65.1 years, standard deviation 11.0) was 18.9% (95% confidence interval: 17.3-20.7). Local treatment was bimodal for 1274 (38.7%) and unimodal for 2021 (61.3%) patients; 1325 (40.2%) had radiation alone and 696 (21.1%) underwent only surgery. The use of bimodal therapy (32.8-42.5%, P = 0.01) and radiation alone (29.3-44.5%, P < 0.001) increased significantly from 1998 to 2008. Bimodal therapy predicted improved CSS (hazard ratios [HR]: 0.68, P < 0.001) and OS (HR: 0.58, P < 0.001) compared with unimodal therapy. For the first 7 months (before survival curve crossing), CSS after radiation therapy alone was similar to surgery alone (HR: 0.86, P = 0.12) while OS was worse for surgery only (HR: 0.70, P = 0.001). However, worse CSS (HR: 1.43, P < 0.001) and OS (HR: 1.46, P < 0.001) after that initial timeframe were found for radiation therapy only. The use of radiation to treat locally advanced mid and distal esophageal cancers increased from 1998 to 2008. Survival was best when both surgery and radiation were used.

This study compared initial year trends in prenatal care and birth outcomes of women enrolled in the Texas Children's Health Insurance Program (CHIP) Perinatal program to trends in Medicaid program women. The study utilized claims data from Community Health Choice (CHC), a health plan in Harris County, Texas that provides coverage to both populations. Quarterly data was analyzed and compared for the first two years of the CHIP Perinatal program (2007-2008) to determine if outcome trends for the CHIP program improved over the outcome trends seen with those enrolled in Medicaid. Study findings indicate an increase in the quarterly prenatal care utilization for the CHIP Perinatal population from 2007 to 2008 and the associated birth weights of babies delivered also had marginal improvements during the same timeframe. Enrollees in Medicaid continued to have overall better outcomes than those enrolled within the CHIP Perinatal program. However, the study showed that the rate of improvement in both prenatal care utilization and birth outcomes were greater for the CHIP Perinatal enrollees than those enrolled in Medicaid. ^ The majority of these improvements were significant when comparing each coverage program and from year to year. Lastly, the study showed that there was a correlation between prenatal care utilization and birth outcomes. However, further analysis of the data could not conclusively indicate that access to prenatal care services provided by the CHIP Perinatal program contributed to the increases observed in utilization and birth outcomes for the study's sample population.^

This paper examines the causalities in mean and variance between stock returns and Foreign Institutional Investment (FII) in India. The analysis in this paper applies the Cross Correlation Function approach from Cheung and Ng (1996), and uses daily data for the timeframe of January 1999 to March 2008 divided into two periods before and after May 2003. Empirical results showed that there are uni-directional causalities in mean and variance from stock returns to FII flows irrelevant of the sample periods, while the reverse causalities in mean and variance are only found in the period beginning with 2003. These results point to FII flows having exerted an impact on the movement of Indian stock prices during the more recent period.

El espacio geográfico, entendido como territorio que da soporte a la vida y a la civilización, ha estado siempre fuertemente supeditado a la presencia de agua. Desde la Prehistoria el hombre otorgó al agua, junto a otros elementos que aseguraban o protegían su vida, un valor superior, por encima de lo humano. Paralelamente y de manera natural, el jardín, en sus inicios en estrecha relación con la agricultura y con el paisaje, fue el ámbito idóneo para la creación de nuevas formas acuáticas artificiales. Este proceso dio lugar a un extenso repertorio de formas compositivas que parece que tuvo en el Renacimiento un punto de inflexión, en el que se observa como la mayoría de recursos y configuraciones básicas del agua estaban ya plenamente establecidas. Esta evolución y sus resultados ha sido el objeto de la primera parte de la tesis: su objetivo ha sido analizar cómo el agua configura, cualifica o puede llegar a construir el jardín y el territorio en el que se inserta, así como establecer las posibles relaciones entre estos dos ámbitos de estudio. Aunque la historia es su fundamento, el planteamiento aquí ha sido más bien conceptual; estudiando los componentes acuáticos desde un punto de vista fundamentalmente compositivo. Esta indagación previa ha sido indispensable para llegar a entender en profundidad los modos en los que el agua se muestra en el jardín y en el paisaje renacentista y manierista, momentos en que se insertan los dos casos de estudio que constituyen la segunda parte de la tesis. Sin caer en un determinismo geográfico extremo, puede admitirse que el jardín, como manifestación cultural intrínsecamente ligada al entorno, depende fuertemente del territorio en el que se asienta; hecho particularmente evidente en aquellas regiones en las que su especial geografía ha sido un claro factor condicionante de su historia. Por ello, Holanda y España han sido las dos localizaciones elegidas para profundizar en este estudio; no tanto por su estrecha relación política y cultural, sino por su profundo y sugerente contraste de medio físico y climático. La Península Ibérica, geográficamente el término del mundo conocido en Occidente hasta el final de la Edad Media, y por esta circunstancia convertida en destino, en territorio de permanencia y fusión, estará además supeditada en la mayoría de su territorio a la falta de agua, siendo a la vez heredera directa del universo y la tradición del jardín meridional originario de Oriente. En el extremo opuesto, Holanda, espacio de transición entre el mar y la tierra firme “real”, es un territorio permeado de humedad y surcado con generosidad por grandes ríos. El país, con una relación ambivalente con el agua, unas veces como amenaza y otras como fuente de nuevas oportunidades, será por el contrario especialmente favorable para el desarrollo de un modelo de jardín septentrional. Un jardín del norte, que no obstante, no surgirá de despejar los bosques, como en el arquetipo nórdico, sino que crecerá sobre planicies antes saturadas de agua o directamente anegadas. El marco temporal de los dos casos concretos ha considerado como fecha inicial 1548, momento en el que Felipe II, aún príncipe, realizó su primer viaje a los Países Bajos, y entró en contacto con el modelo holandés. La extensa producción posterior de jardines de Felipe II, siempre con el agua como protagonista, tuvo como destacado referente la adaptación al suelo y la geografía hispánicos de dicho modelo. Como fecha final se fija 1648, justo un siglo después, fecha coincidente con la firma de la Paz de Westfalia, tratado que supone la total reorganización política del territorio europeo y la pérdida de la hegemonía española en Europa. En Holanda sólo dos años después nacerá Guillermo III de Orange, estatúder de las Provincias Unidas, también futuro rey de Inglaterra, Escocia e Irlanda. Para entonces en Holanda ya se había asistido al desarrollo de un arte propio de jardín, íntimamente ligado al agua, sorprendentemente no demasiado bien conocido y que será uno de los temas de esta investigación. Finalmente, se propone una lectura conjunta de toda esta serie de intervenciones que tienen como argumento el agua, en la que se integra la información procedente de distintos campos de estudio, cada una con su metodología particular. El resultado es una tesis en la que el jardín y el territorio son tratados desde un nuevo y enriquecedor punto de vista. ABSTRACT Geographical space, understood as the territory that provides support to human life and civilization, has always been strongly subjected to the presence of water. From Prehistory man gave to water, along with other elements that ensured or protected life, a higher value than the merely human. At the same time and in a natural way, the garden, in its beginnings with a close relationship with agriculture and landscape, soon developed as the appropriate ground for the creation of new artificial aquatic forms, in a process that seems to have a turning point in the Renaissance, when most of the basic waterworks and resources were already fully established. This development and its outcomes are the subjects of the first part of the thesis: its scope has been to analyse how water configures, qualifies and might even help to construct the garden or landscape attached to it; and to establish the possible links between these two fields of study. Although history based, the point of view here is mainly conceptual, studying the water components understood as composite elements. This exploratory research has been essential to deeply understand the water patterns shown in the Renaissance and Mannerist garden and landscape, periods in which the two case studies are inserted. Without falling in extreme determinism, it can be accepted however, that garden, as a cultural expression linked to environment, is strongly dependant on territorial setting; something particularly evident in those areas where specific geography has been a clear history conditioning factor. This is the reason that leads to choose the Netherlands and Spain to deepen this study, no so much for their interesting cultural and politics relations as for the suggestive and profound contrast of their physical environment and climate. The Iberian Peninsula, geographically the limit of the known world in Occident until the end of the Medium Age, and by this circumstance understood as endpoint, more a destination than a crossroad, a territory of permanence and fusion, but also subjected to water shortage; is thus associated with the universe and tradition of the meridional garden imported from Orient. In the opposite, the Netherlands, a transitional space between the sea and the “real” firm land, is a territory permeated by water and crossed by big rivers. Always with an ambivalent relationship with water, sometimes seen as a threat and sometimes as a source of new opportunities, it was in the other hand the adequate land for the development of a special model of Northern garden. A garden that will not arise, however, from the clearing of woods as in the Nordic archetype, but that will grow on plains originally saturated of water or directly waterlogged. The timeframe of the two cases has 1548 as the initial year, moment in which Philip II, yet prince, made his first trip to the Low Lands and imbibed the Dutch garden model. The later and bountiful garden works of the king, always with the water as the main focus, adapted the imported model to the Spanish ground and geography. The final date is fixed in 1648, just a century after, in coincidence with the Westfalia Peace; a treaty that implied the total political reorganization of the European territory and the end of the Spanish hegemony in the continent. In Holland, only two years later, William III of Orange, Stadtholder of the United Provinces and also future king of England, Scotland and Ireland, was born. But by then the Netherlands had developed an own garden art, closely linked to water. This type garden, surprisingly not very well known, and its relationship with water, will be other of the addressing questions of this work. Finally, the investigation merges the different interventions that have water as an argument, integrating all the fields considered with their particular methodological approaches. The final result is a thesis in which garden and territory are treated from a new and enriching perspective.

A través de la historia aparecen muchas y variadas manifestaciones de cambio, necesarias para afrontar el futuro2 de la humanidad; también de la arquitectura. Estas manifestaciones, alternativas, teorías y proyectos, a menudo denostados por la crítica o dejados de lado por las teorías históricas de carácter generalista, destacan por su capacidad de convertirse en herramientas críticas frente al orden establecido, promoviendo así nuevos imaginarios colectivos. En el contexto temporal que transcurre desde finales de la década de los años cincuenta hasta mediados de los setenta, esa “búsqueda del futuro” no sólo se encuentra totalmente aceptada y popularizada, sino que llega a convertirse en un acto necesario, legitimado por la incorporación de la futurología como ciencia de estudio fundamental. Este contexto resulta el marco idóneo para la aparición de una serie de predicciones arquitectónicas encaminadas a dibujar nuevos caminos posibles para el futuro de la arquitectura, o lo que es lo mismo, para una arquitectura del futuro: “Où vivrons-nous demain ?” (1963) y “Les cités de l'avenir” (1966) del historiador francés Michel Ragon, el número “AD 2000+” (1967) de la revista Architectural Design y “The Future of the Future” (1969) del artista inglés John McHale, “Architecture: action and plan” (1967) y “Experimental Architecture” (1970) de Peter Cook, “Megastructure. Urban futures of the recent past” del crítico inglés Reyner Banham, “Architecture 2000” (1971) del norteamericano Charles Jencks, “Stadstrukturen für morgen” (1971) del suizo Justus Dahinden, “Arthropods: new design futures” (1972) del editor norteamericano Jim Burns y la sección “Cosmorama” (1965-1973) de la revista inglesa Architectural Design, pueden considerarse como las más destacadas. A pesar de lo heterogéneo de sus autores y enfoques, todas ellas gravitan en torno a cuatro alternativas para una redefinición del futuro de la arquitectura: - La incorporación de la arquitectura al heterogéneo espectro formal derivado de la explosión de las artes visuales y la exuberancia y proliferación de los objetos de consumo a través de un CAMBIO DE ESCALA. - La generación de nuevas relaciones que experimenten en torno a los límites entre natural y artificial, o PERVERSIONES NATURALES. - La apertura de un nuevo camino, HACIA UNA ARQUITECTURA VIRTUAL, que experimente con una construcción de ambientes auspiciada por los avances tecnológicos derivados del control perceptivo. - LA MOVILIDAD COMO OPCIÓN DE FUTURO, una respuesta a la aparición de una nueva sociedad en continuo cambio, abogando por estructuras más flexibles en todos los campos del ámbito arquitectónico, de lo urbano a lo doméstico. ABSTRACT of humanity, and of architecture too. Those signs, alternatives, theories and projects, that were often neglected by the critics or left aside by historical theories of general-interest, have an outstanding capacity to become critical tools with regards to the established order, and to promote new collective imagery. Within the timeframe that lasts between late fifties and midseventies, that "quest for the future" is not only accepted and made popular, but it even becomes an act of necessity that is legitimized by the incorporation of futurology as a key scientific field of study. This timeframe provides the most suitable context for the appearance of a series of architectonical predictions that are aimed to define new potential paths for the future architecture to follow, in other words, an architecture of the future: "Où vivrons-nous demain?" (1963) y "Les cités de l'avenir" (1966) from French historian Michel Ragon, issue number "AD 2000+" (1967) of Architectural Design magazine and "The Future of the Future" (1969) from English artist John McHale, "Architecture: action and plan" (1967) and "Experimental Architecture" (1970) from Peter Cook, "Megastructure. Urban futures of the recent past" from English critic Reyner Banham, "Architecture 2000" (1971) from North-American Charles Jencks, "Stadstrukturen für morgen" (1971) from Swiss Justus Dahinden, "Arthropods: new design futures" (1972) from North-American editor Jim Burns and the section "Cosmorama" (1965-73) from English magazine Architectural Design, can be considered as the most prominent architectonical predictions of that time. Despite the heterogeneity of authors and approaches, all of them are built around four alternatives that are aimed to re-define the future of architecture: - The incorporation of architecture to the heterogeneous formal spectrum of visual arts and the exuberance and the proliferation of objects of massive consumerism through an operation of CHANGE IN SCALE. - The production of new relationships aimed to experiment around the limits between natural and artificial, in other words, NATURAL PERVERSIONS. - A new road TOWARDS VIRTUAL ARCHITECTURE, to enable experiences with ambiance construction that are favored by technological advances derived from the control of perception. - MOVILITY AS AN OPTION FOR THE FUTURE, a response to the appearance of a new ever changing society, a bet on more flexible structures in all areas of architecture, from urban to domestic scale.

La tesis doctoral se centra en la posibilidad de entender que la práctica de arquitectura puede encontrar en las prácticas comunicativas un apoyo instrumental, que sobrepasa cualquier simplificación clásica del uso de los medios como una mera aplicación superficial, post-producida o sencillamente promocional. A partir de esta premisa se exponen casos del último cuarto del siglo XX y se detecta que amenazas como el riesgo de la banalización, la posible saturación de la imagen pública o la previsible asociación incorrecta con otros individuos en presentaciones grupales o por temáticas, han podido influir en un crecimiento notable de la adquisición de control, por parte de los arquitectos, en sus oportunidades mediáticas. Esto es, como si la arquitectura hubiera empezado a superar y optimizar algo inevitable, que las fórmulas expositivas y las publicaciones, o más bien del exponer(se) y publicar(se), son herramientas disponibles para activar algún tipo de gestión intelectual de la comunicación e información circulante sobre si misma. Esta práctica de “autoedición” se analiza en un periodo concreto de la trayectoria de OMA -Office for Metropolitan Architecture-, estudio considerado pionero en el uso eficiente, oportunista y personalizado de los medios. Así, la segunda parte de la tesis se ocupa del análisis de su conocida monografía S,M,L,XL (1995), un volumen que contó con gran participación por parte de sus protagonistas durante la edición, y de cuyo proceso de producción apenas se había investigado. Esta publicación señaló un punto de inflexión en su género alterando todo formato y restricciones anteriores, y se ha convertido en un volumen emblemático para la disciplina que ninguna réplica posterior ha podido superar. Aquí se presenta a su vez como el desencadenante de la construcción de un “gran evento” que concluye en la transformación de la identidad de OMA en 10 años, paradójicamente entre el nacimiento de la Fundación Groszstadt y el arranque de la actividad de AMO, dos entidades paralelas clave anexas a OMA. Este planteamiento deviene de cómo la investigación desvela que S,M,L,XL es una pieza más, central pero no independiente, dentro de una suma de acciones e individuos, así como otras publicaciones, exposiciones, eventos y también artículos ensayados y proyectos, en particular Bigness, Generic City, Euralille y los concursos de 1989. Son significativos aspectos como la apertura a una autoría múltiple, encabezada por Rem Koolhaas y el diseñador gráfico Bruce Mau, acompañados en los agradecimientos de la editora Jennifer Sigler y cerca de una centena de nombres, cuyas aportaciones no necesariamente se basan en la construcción de fragmentos del libro. La supresión de ciertos límites permite superar también las tareas inicialmente relevantes en la edición de una publicación. Un objetivo general de la tesis es también la reflexión sobre relaciones anteriormente cuestionadas, como la establecida entre la arquitectura y los mercados o la economía. Tomando como punto de partida la idea de “design intelligence” sugerida por Michael Speaks (2001), se extrae de sus argumentos que lo esencial es el hallazgo de la singularidad o inteligencia propia de cada estudio de arquitectura o diseño. Asimismo se explora si en la construcción de ese tipo de fórmulas magistrales se alojaban también combinaciones de interés y productivas entre asuntos como la eficiencia y la creatividad, o la organización y las ideas. En esta dinámica de relaciones bidireccionales, y en ese presente de exceso de información, se fundamenta la propuesta de una equivalencia más evidenciada entre la “socialización” del trabajo del arquitecto, al compartirlo públicamente e introducir nuevas conversaciones, y la relación inversa a partir del trabajo sobre la “socialización” misma. Como si la consciencia sobre el uso de los medios pudiera ser efectivamente instrumental, y contribuir al desarrollo de la práctica de arquitectura, desde una perspectiva idealmente comprometida e intelectual. ABSTRACT The dissertation argues the possibility to understand that the practice of architecture can find an instrumental support in the practices of communication, overcoming any classical simplification of the use of media, generally reduced to superficial treatments or promotional efforts. Thus some cases of the last decades of the 20th century are presented. Some threats detected, such as the risk of triviality, the saturation of the public image or the foreseeable wrong association among individuals when they are introduced as part of thematic groups, might have encouraged a noticeable increase of command taken by architects when there is chance to intervene in a media environment. In other words, it can be argued that architecture has started to overcome and optimize the inevitable, the fact that exhibition formulas and publications, or simply the practice of (self)exhibition or (self)publication, are tools at our disposal for the activation of any kind of intellectual management of communication and circulating information about itself. This practice of “self-edition” is analyzed in a specific timeframe of OMA’s trajectory, an office that is considered as a ground-breaking actor in the efficient and opportunistic use of media. Then the second part of the thesis dissects their monograph S,M,L,XL (1995), a volume in which its main characters were deeply involved in terms of edition and design, a process barely analyzed up to now. This publication marked a turning point in its own genre, disrupting old formats and traditional restrictions. It became such an emblematic volume for the discipline that none of the following attempts of replica has ever been able to improve this precedent. Here, the book is also presented as the element that triggers the construction of a “big event” that concludes in the transformation of OMA identity in 10 years. Paradoxically, between the birth of the Groszstadt Foundation and the early steps of AMO, both two entities parallel and connected to OMA. This positions emerge from how the research unveils that S,M,L,XL is one more piece, a key one but not an unrelated element, within a sum of actions and individuals, as well as other publications, exhibitions, articles and projects, in particular Bigness, Generic City, Euralille and the competitions of 1989. Among the remarkable innovations of the monograph, there is an outstanding openness to a regime of multiple authorship, headed by Rem Koolhaas and the graphic designer Bruce Mau, who share the acknowledgements page with the editor, Jennifer Sigler, and almost 100 people, not necessarily responsible for specific fragments of the book. In this respect, the dissolution of certain limits made possible that the expected tasks in the edition of a publication could be trespassed. A general goal of the thesis is also to open a debate on typically questioned relations, particularly between architecture and markets or economy. Using the idea of “design intelligence”, outlined by Michael Speaks in 2001, the thesis pulls out its essence, basically the interest in detecting the singularity, or particular intelligence of every office of architecture and design. Then it explores if in the construction of this kind of ingenious formulas one could find interesting and useful combinations among issues like efficiency and creativity, or organization and ideas. This dynamic of bidirectional relations, rescued urgently at this present moment of excess of information, is based on the proposal for a more evident equivalence between the “socialization” of the work in architecture, anytime it is shared in public, and the opposite concept, the work on the proper act of “socialization” itself. As if a new awareness of the capacities of the use of media could turn it into an instrumental force, capable of contributing to the development of the practice of architecture, from an ideally committed and intelectual perspective.

The latest round of climate negotiations that took place in Warsaw (Conference of Parties, COP19) finally resulted in a decision to agree on a timeframe for the new agreement due in COP21 in Paris in 2015, and on ways to enhance the levels of ambition in pre-2020 mitigation pledges. Specifically, Warsaw produced two milestones: i) Parties were asked to communicate “intended nationally-determined contributions” by March 2015 and ii) the Ad-hoc Working Group on the Durban Platform for Enhanced Action was requested to identify before COP20 in Lima, the information that Parties will provide when putting forward their contributions. This Commentary by Noriko Fujiwara explores what the Warsaw decision means in practice and offers some preliminary ideas about what is still needed.

President Viktor Yanukovych and his Party of Regions have been repeating the pledge to decentralise power in Ukraine and to give local government a greater decision-making role ever since the party appeared on the Ukrainian political scene. The implementation of this reform is crucial both for the economic recovery of Ukraine’s regions and the overall modernisation efforts of the Ukrainian state. At present relations between central government and the regions are regulated by Soviet-era legislation that fails to address the modern-day challenges facing Ukraine. The political elite in the country, including the opposition, appear to have reached consensus on the importance of the decentralisation reform. The first attempts to implement changes in this area were made in the late 1990s, followed by a comprehensive reform programme developed between 2007 and 2009 by Yulia Tymoshenko’s government. In 2012, the Constitutional Assembly under the President of Ukraine appointed a team of experts who drafted a document detailing the reform of local government and the territorial organisation of power1. The document envisages the implementation of what effectively are two major reforms: (1) an administrative-territorial reform, which would help consolidate the fragmented administrative structure, creating larger and more economically self-sufficient administrative units, and (2) local government reform, focusing on creating clearly defined powers for local authorities with a view to securing government funding for specific tasks delegated from central government. Nonetheless, despite these measures, and in spite of the rhetoric coming from President Yanukovych and other members of the Party of Regions, it seems unlikely that the reform will be implemented in the foreseeable future. A series of concrete political decisions taken by the president over the past three years indicate that Yanukovych has not abandoned his plan to build a highly centralised political system. This in turn limits the capacity to govern of local authorities and further restricts the sources of funding for Ukraine’s regions. This apparent resistance to change stems from the fact that by implementing the proposed reforms, the president and his political allies would be forced to relinquish much of their control over the political processes taking place in the country and would have to free up the distribution of budgetary resources between Kyiv and the regions. The implementation of the reform within the specified timeframe (i.e. by 2015) is also unlikely due to the upcoming presidential election and the deteriorating economic situation in Ukraine. Without a comprehensive reform of local government, however, Ukraine will be unable to undertake effective modernisation measures, which are key for the socio-economic development of the country’s regions.

Belarus generated a surplus at US$1.9 billion in foreign trade in goods and services in the first four months of 2012 as compared to a deficit of US$2.8 billion for the same timeframe a year earlier. Minsk owes this, its highest positive trade balance since 1991, mainly to a significant increase in exports of petroleum products manufactured by the refineries in Navapolatsk and Mazyr. This is a consequence of the favourable contract for supplies of Russian oil until 2015 which Belarus signed in December last year. This contract has resulted in a de facto resumption of Russia subsidising Belarus. The favourable conditions of Russian oil supplies will allow the Belarusian refineries to remain the driving force of the country’s economy, and the Belarusian government will not allow them to be privatised, which Russia has been seeking for years. The two refineries initiated an ambitious modernisation programme, which is aimed at increasing their output and improving the quality of their production. Owing to this, their share in the market of petroleum products in the region, including on the Polish market, may grow within the next few years.

Since taking power in 2009, the Alliance for European Integration (AIE) has been trying to end Moldova’s dependence on Russian gas. Currently, natural gas accounts for about 50% of the country’s energy balance (excluding Transnistria), and Gazprom has a monopoly on the supply of gas to the republic. The key element of Chișinău’s diversification project is the construction of the Iasi-Ungheni pipeline, which is designed to link the Moldovan and Romanian gas transmission networks, and consequently make it possible for Moldova to purchase gas from countries other than Russia. Despite significant delays, construction work on the interconnector began in August 2013. The Moldovan government sees ensuring energy independence from Russia as its top priority. The significance and urgency of the project reflect Chișinău’s frustration at Moscow’s continued attempts to use its monopoly of Moldova’s energy sector to exert political pressure on the republic. Nonetheless, despite numerous declarations by Moldovan and Romanian politicians, the Iasi- -Ungheni pipeline will not end Moldova’s dependence on Russian gas before the end of the current decade. This timeframe is unrealistic for two reasons: first, because an additional gas pipeline from Ungheni to Chisinau and a compression station must be constructed, which will take at least five years and will require significant investment; and second, because of the unrelenting opposition to the project coming from Gazprom, which currently controls Moldova’s pipelines and will likely try to torpedo any energy diversification attempts. Independence from Russian gas will only be possible after the the Gazprom-controlled Moldova-GAZ, the operator of the Moldovan transmission network and the country’s importer of natural gas, is divided. The division of the company has in fact been envisaged in the EU’s Third Energy Package, which is meant to be implemented by Moldova in 2020.

The mountain ranges and coastlines of Washington State have steep slopes, and they are susceptible to landslides triggered by intense rainstorms, rapid snow melts, earthquakes, and rivers and waves removing slope stability. Over a 30-year timespan (1984-2014 and includes State Route (SR) 530), a total of 28 deep-seated landslides caused 300 million dollars of damage and 45 deaths (DGER, 2015). During that same timeframe, ten storm events triggered shallow landslides and debris flows across the state, resulting in nine deaths (DGER, 2015). The loss of 43 people, due to the SR 530 complex reactivating and moving at a rate and distance unexpected to residents, highlighted the need for an inventory of the stateís landslides. With only 13% of the state mapped (Lombardo et al., 2015), the intention of this statewide inventory is to communicate hazards to citizens and decision makers. In order to compile an accurate and consistent landslide inventory, Washington needs to adopt a graphic information system (GIS) based mapping protocol. A mapping protocol provides consistency for measuring and recording information about landslides, including such information as the type of landslide, the material involved, and the size of the movement. The state of Oregon shares similar landslide problems as Washington, and it created a GIS-based mapping protocol designed to inform its residents, while also saving money and reducing costly hours in the field (Burns and Madin, 2009). In order to determine if the Oregon Department of Geology and Mineral Industries (DOGAMI) protocol, developed by Burns and Madin (2009), could serve as the basis for establishing Washingtonís protocol, I used the office-based DOGAMI protocol to map landslides along a 40-50 km (25-30 mile) shoreline in Thurston County, Washington. I then compared my results to the field-based landslide inventory created in 2009 by the Washington Division of Geology and Earth Resources (DGER) along this same shoreline. If the landslide area I mapped reasonably equaled the area of the DGER (2009) inventory, I would consider the DOGAMI protocol useful for Washington, too. Utilizing 1m resolution lidar flown for Thurston County in 2011 and a GIS platform, I mapped 36 landslide deposits and scarp flanks, covering a total area of 879,530 m2 (9,467,160 ft2). I also found 48 recent events within these deposits. With an exception of two slides, all of the movements occurred within the last fifty years. Along this same coastline, the DGER (2009) recorded 159 individual landslides and complexes, for a total area of 3,256,570 m2 (35,053,400 ft2). At a first glance it appears the DGER (2009) effort found a larger total number and total area of landslides. However, in addition to their field inventory, they digitized landslides previously mapped by other researchers, and they did not field confirm these landslides, which cover a total area of 2,093,860 m2 (22,538,150 ft2) (DGER, 2009). With this questionable landslide area removed and the toes and underwater landslides accounted for because I did not have a bathymetry dataset, my results are within 6,580 m2 (70,840 ft2) of the DGERís results. This similarity shows that the DOGAMI protocol provides a consistent and accurate approach to creating a landslide inventory. With a few additional modifications, I recommend that Washington State adopts the DOGAMI protocol. Acquiring additional 1m lidar and adopting a modified DOGAMI protocol poises the DGER to map the remaining 87% of the state, with an ultimate goal of informing citizens and decision makers of the locations and frequencies of landslide hazards on a user-friendly GIS platform.
Resumo:
The term secretome has been defined as a set of secreted proteins (Grimmond et al. [2003] Genome Res 13:1350-1359). The term secreted protein encompasses all proteins exported from the cell including growth factors, extracellular proteinases, morphogens, and extracellular matrix molecules. Defining the genes encoding secreted proteins that change in expression during organogenesis, the dynamic secretome, is likely to point to key drivers of morphogenesis. Such secreted proteins are involved in the reciprocal interactions between the ureteric bud (UB) and the metanephric mesenchyme (AM) that occur during organogenesis of the metanephros. Some key metanephric secreted proteins have been identified, but many remain to be determined. In this study, microarray expression profiling of E10.5, E11.5, and E13.5 kidney and consensus bioinformatic analysis were used to define a dynamic secretome of early metanephric development. In situ hybridisation was used to confirm microarray results and clarify spatial expression patterns for these genes. Forty-one secreted factors were dynamically expressed between the E10.5 and E13.5 timeframe profiled, and 25 of these factors had not previously been implicated in kidney development. A text-based anatomical ontology was used to spatially annotate the expression pattern of these genes in cultured metanephric explants.
