La Organización de Cooperación de Shanghái (OCS): ¿una alianza estratégica Sino-Rusa para el control de Asia Central? (2001-2014)

La presente monografía pretende analizar en qué medida el co-liderazgo sino-ruso de la Organización de Cooperación de Shanghái puede condicionar la hegemonía estadounidense en Asia Central. Esta investigación defiende que los objetivos del co-liderazgo sino-ruso de la OCS - garantizar un orden multipolar del Sistema Internacional; obtener el acceso, control y explotación de los recursos (naturales, minerales e hídricos); disminuir la influencia política y militar de Estados Unidos en dicho pivote geopolítico - evidencian una contraposición al código geopolítico estadounidense en Asia Central, lo cual genera un limitante a su proyecto de hegemonía en la región. Para sustentar lo anterior se utilizan categorías analíticas propias de la Geopolítica de autores como Zbigniew Brzezinski, Saul Cohen y Peter Taylor, las cuales se contrastan con las estrategias de Rusia, China y Estados Unidos en Asia Central.

Forma parte de una colección de libros de ficción estructurada en varias etapas, desde la diez a la catorce, y que tiene como finalidad que los alumnos de entre 7 y 11 años adquieran una mayor capacidad lectora. Para ello, las formas narrativas de las historias se hacen cada vez más complejas y se amplia el vocabulario de ellas; se aumentan el número de páginas y de texto y se reduce el número de ilustraciones.Jamie es un huérfano que vive en las calles de Plymouth y mendiga para comer. Una noche en la taberna 'El Pelícano' mientras, él suplica con la frase 'una canción para un pastel', alguien le está observando y, desde entonces, su vida corre peligro.

Progress on “Changing coastlines: data assimilation for morphodynamic prediction and predictability”

The task of assessing the likelihood and extent of coastal flooding is hampered by the lack of detailed information on near-shore bathymetry. This is required as an input for coastal inundation models, and in some cases the variability in the bathymetry can impact the prediction of those areas likely to be affected by flooding in a storm. The constant monitoring and data collection that would be required to characterise the near-shore bathymetry over large coastal areas is impractical, leaving the option of running morphodynamic models to predict the likely bathymetry at any given time. However, if the models are inaccurate the errors may be significant if incorrect bathymetry is used to predict possible flood risks. This project is assessing the use of data assimilation techniques to improve the predictions from a simple model, by rigorously incorporating observations of the bathymetry into the model, to bring the model closer to the actual situation. Currently we are concentrating on Morecambe Bay as a primary study site, as it has a highly dynamic inter-tidal zone, with changes in the course of channels in this zone impacting the likely locations of flooding from storms. We are working with SAR images, LiDAR, and swath bathymetry to give us the observations over a 2.5 year period running from May 2003 – November 2005. We have a LiDAR image of the entire inter-tidal zone for November 2005 to use as validation data. We have implemented a 3D-Var data assimilation scheme, to investigate the improvements in performance of the data assimilation compared to the previous scheme which was based on the optimal interpolation method. We are currently evaluating these different data assimilation techniques, using 22 SAR data observations. We will also include the LiDAR data and swath bathymetry to improve the observational coverage, and investigate the impact of different types of observation on the predictive ability of the model. We are also assessing the ability of the data assimilation scheme to recover the correct bathymetry after storm events, which can dramatically change the bathymetry in a short period of time.

Promoting core maths - background, evidence, plans, opportunities, and challenges

This article discusses some of the issues relating to the promotion of Core Maths to students, parents, schools and colleges and their senior leadership teams, and also to employers and higher education (HE). Some challenges are highlighted, and addressed, with suggestions for ways forward to secure the future of Core Maths and widespread adoption by all stakeholders. A summary of the background reports that led to the introduction of Core Maths, and the related educational landscape prior to its introduction, is included.

Vertical migration during tidal transport of megalopae of Necora puber in coastal shallow waters during daytime

For meroplanktonic larvae that must settle in coastal areas, their successful return to the shore is determined largely by physical transport processes; however, many organisms perform vertical movements to aid successful recruitment. In this study, daytime tidal vertical migration of megalopae of the velvet swimming crab Necora puber was investigated across two different exposures in the shallow waters of Plymouth Sound. Crabs were collected using a plankton net at the surface and near the bottom during flood and ebb tides. Distribution of the pelagic postlarvae was patchy and the abundance varied spatially in tens and thousands of metres. In temporal scales, the annual pattern was dominated by low occurrence of megalopae, punctuated by episodic peaks of high abundance. Most megalopae were collected at the surface irrespective of the tidal phase. The effect of wave exposure on the vertical migration of megalopae was not clear, although there was a general higher abundance of megalopae on exposed shores. Daytime abundance in the water column appears to be regulated by the tidal cycle, as megalopae were more abundant during flood than ebb tides. Although the megalopae do not appear to make large vertical migrations, this behaviour should produce a net shoreward transport. © 2005 Elsevier Ltd. All rights reserved.
