WAIS Seminar: Research Discussion: Open Data at the Hampshire Hub

This is a research discussion about the Hampshire Hub - see http://protohub.net/. The aim is to find out more about the project, and discuss future collaboration and sharing of ideas. Mark Braggins (Hampshire Hub Partnership) will introduce the Hampshire Hub programme, setting out its main objectives, work done to-date, next steps including the Hampshire data store (which will use the PublishMyData linked data platform), and opportunities for University of Southampton to engage with the programme , including the forthcoming Hampshire Hackathons Bill Roberts (Swirrl) will give an overview of the PublishMyData platform, and how it will help deliver the objectives of the Hampshire Hub. He will detail some of the new functionality being added to the platform Steve Peters (DCLG Open Data Communities) will focus on developing a web of data that blends and combines local and national data sources around localities, and common topics/themes. This will include observations on the potential employing emerging new, big data sources to help deliver more effective, better targeted public services. Steve will illustrate this with practical examples of DCLG’s work to publish its own data in a SPARQL end-point, so that it can be used over the web alongside related 3rd party sources. He will share examples of some of the practical challenges, particularly around querying and re-using geographic LinkedData in a federated world of SPARQL end-point.

Sustainable urban criteria in the urban periphery of Guadalajara

The study of the growth of large cities, in the urban periphery or the peri-urban areas specifically, it relates to environmental degradation due to urbanization, if it is estimated that since 2008 more than half of the world population living in urban areas, this sector is affected as it presents overcrowding, segregation and deterioration of physical conditions, which will impact on the social aspects within localities. This great urban growth has usually developed with the lack of environmental planning.So it is necessary to include urban development, guidelines towards environmental conservation and rehabilitation of the territory. The future of cities will depend largely on the actions taken now. As urban development inevitably requires planning urban settlements through sustainable development so as to provide alternative technologies, based on the reality of Latin American countries.In the peripheral area of the Metropolitan Zone of Guadalajara, is taken as a case study of the town of La Venta del Astillero, which by its nature allows access and functionality to develop a set of criteria and indicators to urban sustainability, which can take as a model for other communities in the urban periphery.

Glocalización: Nuevos Enfoques Teóricos Sobre el Desarrollo Regional (Sub Nacional) en el Contexto de la Integración Económica y de la Globalización

El autor aborda en este artículo cuestiones atinentes al espacio, la geografía y la organización del territorio a partir del tema del desarrollo. Para fundamentar su tesis según la cual varios de los factores que impulsan la globalización tienen una base territorial, como el comercio internacional de bienes y servicios, el cambio tecnológico o los flujos internacionales, apela a las categorías del desarrollo social y las sitúa en dos dimensiones. En una primera instancia, el autor toma en cuenta la lógica intranacional de despliegue de los factores políticos, ambientales y comerciales; en un segundo momento destaca el papel de las regiones y las localidades en la reconstrucción del sistema económico mundial para concluir que en un contexto todavía incierto se destaca la configuración de regiones megapolitanas que funcionan como motores regionales en la nueva economía global.---The author handles this article with questions that regard space,geography and territorial organisation based on the topic of development. To support his thesis that refers to the way in which various factors that give an impulse to globalisation have a territorial base, such as the international commerce of goods and services, technological change or international networks, the author utilises social development categories and places them in two dimensions. Initially, the author takes into account the international logic of the development of commercial, environment and political factors. Secondly, he emphasizes the role of regions and localities in the reconstruction of the global economic system to conclude that in a present uncertain context it is worth pointing out the configuration of megapolitanregions that function as regional motors in a new global economy.

Iglesias y partidos políticos: la estrategia electoral del MIRA en las elecciones al Senado del 2006 y el 2010 en Bogotá

La relación entre la política y la religión ha sido un fenómeno constante en la historia de Colombia, pero gracias a la pluralización religiosa manifestada en la Constitución Política de 1991 se abrió el panorama político para la participación política de congregaciones confesionales, diferentes a la católica. En este contexto de participación pluralista surgió la presente investigación que tiene como propósito la caracterización de la relación entre la Iglesia de Dios Ministerial de Jesucristo Internacional y el Movimiento Político MIRA a partir de la eficiencia electoral obtenida en las elecciones al Senado del 2006 y el 2010 en Bogotá. Dando como resultado una indiscutible relación entre la localización de una sede de la IDMJI y la concentración electoral por el MIRA en las localidades de Bogotá.

Tratado de libre comercio entre Colombia e Israel. Perspectivas generales y oportunidades para el sector agrícola colombiano

Las estrategias tendientes a la diversificación de los mercados de exportación e internacionalización de la economía por parte del gobierno colombiano y sus políticas gubernamentales han incluido la firma de una serie de Tratados de Libre Comercio, entre ellos el TLC de última generación firmado con El Estado de Israel. Estos tratados además de abordar temas tradicionales de comercio, tratan nuevos capítulos en inversiones y servicios. Así mismo se analizan las principales políticas por parte del gobierno de Israel para la competitividad en términos empresariales y sociales. Más adelante se consideran aspectos generales de la economía colombiana y se analiza la relación comercial bilateral entre el Estado de Israel y la República de Colombia para entender su comportamiento histórico y el ambiente actual. Finalmente se hace un énfasis en el sector agrícola de Israel y sus aspectos que lo han dirigido al éxito, una observación corta del sector en Colombia y luego aspectos adicionales para a facilitación del comercio con Israel. El estudio va dirigido a empresarios, compañías o entes públicos a nivel local e internacional que vean en el sector agrícola colombiano una oportunidad de desarrollo, aprovechando los beneficios de comercio y conocimiento, con el objetivo de mejorar la competitividad y productividad del sector en Colombia. Se utilizan metodologías tanto cuantitativas como cualitativas para la investigación y análisis de caso tomando la información correspondiente de fuentes verídicas e independientes para así poder reseñar y describir las oportunidades y retos del sector agrícola.

Cystoseira-dominated assemblages from sheltered areas in the Mediterranean sea : diversity, distribution and effects of pollution

Les algues del gènere Cystoseira són els principals organismes formadors d'estructura en fons rocosos ben il·luminats del Mar Mediterrani. Formen unes comunitats molt estructurades que s'assemblen ecològicament als boscos terrestres i que són sensibles als impactes antròpics. Aquesta tesi s'ha centrat en l'estudi de les espècies i comunitats dominades per Cystoseira que es troben en ambients calmats, és a dir, en petites cales i/o badies. S'han abordat diversos aspectes com són la distribució, composició, estructura i biogeografia d'aquestes comunitats, així com els efectes de la contaminació sobre les mateixes. Per una banda, s'ha documentat l'estat actual de les comunitats dominades per C. crinita a nombrosos llocs al llarg de tot el Mediterrani, aportant informació sobre la seva composició, estructura, variació biogeogràfica i dinàmica de la comunitat a llarg termini. S'ha documentat la desaparició de diverses espècies de Cystoseira en zones afectades per impactes antròpics diversos i s'ha proporcionat la primera evidència experimental de la desaparició d'espècies de Cystoseira a causa de la contaminació.

Manta: una ciudad-puerto en el siglo XIX. Economía regional y mercado mundial (Estudios)

El ensayo analiza el surgimiento de la ciudad de Manta como estación de enlace entre la región de Manabí y el mercado mundial en el siglo XIX. Esta región económica estuvo integrada por un sistema de pequeñas localidades, cada una de las cuales cumplía una función determinada. El puerto de Manta experimentó un sorprendente despegue debido al auge manufacturero de los sombreros de paja toquilla y, más tarde, al auge agroexportador de la tagua y el cacao. Estudia, además, el proceso de recolonización por parte de grupos blanco-mestizos y la segmentación del espacio entre los nuev s inmigrantes y los descendientes de los antiguos indios.

Localismo y miradas urbanas: las monografías locales en el Ecuador del siglo XX (Estudios)

La construcción del Estado nacional involucró la conformación de las localidades y la difusión de los idearios y símbolos nacionales. Las monografías locales transmitieron estos símbolos con el propósito de vincular las patrias chicas a la nación. Las miradas urbanas locales se convirtieron, a menudo, en imágenes del progreso y retratos de las élites locales. El período de mayor producción de estas monografías -1920 y 1960- coincide con el auge de la prensa regional. Esto revela la relativa eficacia con que se propagaron los símbolos patrios durante el período de profundización de la división político-administrativa y la constitución de los poderes locales en el Ecuador.

Annual textural banding in Holocene estuarine silts, Severn Estuary Levels (SW Britain): patterns, cause and implications

A high-resolution textural study has been made of laminated and banded estuarine silts exposed intertidally at representative localities and horizons in the Holocene deposits of the Severn Estuary Levels. The laminae, on a submillimetre to millimetre scale, are sharp-based, graded couplets formed of a lower silty part overlain by a finer-textured clayey element. The centimetre- to decimetre-scale banding is formed of laminae in alternating, gradually intergrading sets of relatively coarse and relative fine-grained examples. At outcrop in the field, the banding is recognizable because the coarse sets prove to be recessive to varying degrees under the influence of weathering and current action. Independent evidence at two localities points toward an annual origin for the banding; at a third it arose during part of what appears to have been a relatively short period. Quantified physical arguments suggest that the textural banding is a response of suspended fine sediment to marked seasonal changes in sea temperature and windiness. The banded silts occur in four distinct stratigraphical contexts and record high deposition rates (order 0.01-0.1 m/yr). Because physical factors determine their textures, the silts potentially afford insights in all contexts into aspects of changing Holocene climatic conditions. In one context, the thickness of the bands points to high (order 0.01-0.1 m/yr) but comparatively short-lived (order 10s-100s yrs) rates of relative water-level rise. In the others, however, the banding has no implications for sea-level behaviour, and simply records gross environmental disequilibrium, for example, the recovery of mudflats/marshes after an erosional episode. Similarly, because on account of their rapid accumulation the banded silts preserve animal and human tracks and trackways especially well, they provide an archive of animal and human behaviour in the area during the Holocene.

REMOTE SENSING OF AEOLIAN DUST PRODUCTION AND DISTRIBUTION

Airborne dust is of concern due to hazards in the localities affected by erosion, transport and deposition, but it is also of global concern due to uncertainties over its role in radiative forcing of climate. In order to model the environmental impact of dust, we need a better knowledge of sources and transport processes. Satellite remote sensing has been instrumental in providing this knowledge, through long time series of observations of atmospheric dust transport. Three remote sensing methodologies have been used, and are reviewed briefly in this paper. Firstly the use of observations from the Total Ozone Mapping Spectrometer (TOMS), secondly the use of the Infrared Difference Dust Index (IDDI) from Meterosat infrared data, thirdly the use of MODIS images from the rapid response system. These data have highlighted the major global sources of dust, mist of which are associated with endoreic drainage basins in deserts, which held lakes during Quaternary humid climate phases, and identified the Bodele Depression in Tchad as the dustiest place on Earth.

Pliocene seasonality across the North Atlantic inferred from cheilostome bryozoans

Previous studies have shown an inverse correlation between zooid size in cheilostome bryozoans and ambient water temperature. This relationship underlies the MART technique which uses intracolonial variation in zooid size to predict mean annual range in temperature experienced by bryozoan colonies during their life. Here we apply the MART technique to study Early and Mid Pliocene bryozoans from Central America (Panama, Costa Rica), the USA (Florida, South Carolina, North Carolina, Virginia) and the UK (Suffolk) to reconstruct palaeoseasonality across a range of latitudes for the North Atlantic during the Pliocene Epoch. Compared to the present-day, our analyses suggest greater seasonality (ca 4.5 degrees C) in the southern Caribbean at the time of Cayo Agua Formation deposition (ca 4.25 Ma), in keeping with inferred upwelling prior to the closure of the isthmian barrier at 2.7 Ma. Bryozoans also indicate seasonal upwelling on the Gulf Coast of Florida in a similar manner to the present-day. Because upwelling can be highly localised and prone to spatial and temporal variation in the Gulf of Mexico today, it contributes little to a broad understanding of Pliocene North Atlantic waters. However, MART estimates for the coastal plain region indicate a general reduction in the annual range in temperature relative to the present, suggesting that the colder surface waters that today reach south to Cape Hatteras had less influence in Early to Mid Pliocene times. These results, along with evidence from other proxies, strongly support reduced seasonality and warmer conditions along the eastern seaboard of the USA in the Early to Mid Pliocene. Finally, the MART estimates amongst Coralline Crag localities provide evidence for an increased annual range in temperature in the southern North Sea than at present. Our study shows that bryozoan MART estimates provide a powerful, independent proxy for palaeoseasonality and is the first to demonstrate that the MART technique can be applied to infer palaeoclimates across a wide range of latitudes focusing on a variety of geological formations and geographical regions.

Local adaptation in moss life histories: population-level variation and a reciprocal transplant experiment

We examine the extent of population-level differentiation in life history traits of Pogonatum aloides, Polytrichum commune and Polytrichum juniperinum (Polytrichaceae) between upland and lowland localities within Britain. Reciprocal transplant studies are used to estimate the relative importance of genetic versus environmental effects on observed differences. We demonstrate significant life history differentiation between moss populations, and show that at least some of these are genetically determined, although environment and phenotypic plasticity are also significant components of the observed variation. The transplant experiments indicate divergence among populations in plasticity of male reproductive effort and of investment in vegetative shoots by females. Two tradeoffs are identified; one between the number and the size of spores, and the second between reproduction by spores versus vegetative reproduction. The patterns of life history variation observed between populations of Polytrichum juniperinum are consistent with selection along these implied tradeoff curves, and we propose that they reflect selective pressures arising from the spatial and demographic distribution of mortality at upland versus lowland sites. The results underscore the need for more studies of intra-specific life history variation in mosses.

Are rare species rare or just overlooked? Assessing the distribution of the freshwater bryozoan, Lophopus crystallinus

Given the widespread degradation of freshwater habitats, assessing the distributions of species that may be negatively or positively impacted should be of general interest. However, determining distributions of freshwater organisms that are small and patchily distributed and attached or sedentary is particularly problematic, as it is time consuming, inaccurate, and nearly impossible when the focal species is rare. Here we illustrate the use of indirect sampling approaches to survey the distribution of the rare freshwater bryozoan Lophopus crystallinus, a priority species in the UK Biodiversity Action Plan [Anonymous, 1999. UK Biodiversity Group Tranche 2 Action Plans. Invertebrates, Vol. 4. Environment Agency, Peterborough, pp. 437-439.1. By utilising two complementary methods for sampling bryozoan propagules (statoblasts), namely the collection of debris samples and sediment cores, we achieved an efficient and integrative sampling of habitats across spatial and temporal scales. Analysis of 154 debris samples, encompassing 62 rivers and lakes, identified at least 16 new populations while analysis of 26 sediment cores provided evidence of current or very recent (in the last 10-20 years) occurrence in a further six localities. These results represent a more than 10-fold increase in the current recorded distribution of the species in the UK. Logistic regression analysis provided evidence that L. crystallinus is generally found in lowland sites and is tolerant of eutrophication. Our study exemplifies how integrative and indirect sampling approaches can greatly aid in assessing the conservation status of rare aquatic species and reveals, in this case, that the focal species is less rare than previously appreciated.

Ecology of sponge assemblages (Porifera) in the Wakatobi region, south-east Sulawesi, Indonesia: richness and abundance

The influence of sedimentation, depth and substratum angle on sponge assemblages in the Wakatobi region, south-eastern Sulawesi, Indonesia was considered. Sponge assemblages were sampled from two reef localities. The first reef (Sampela) was highly impacted by high sedimentation rates with fine sediment particles that settle slowly, while the second (Hoga) experienced only fast settling coarse sediment with lower overall sedimentation rates. Sponge assemblages were sampled (area occupied and numbers) on the reef fiat (0 m) and at 5 (reef crest), 10 and 15 m (15 m at Hoga only). Some significant (P < 0.001) differences were observed in the area occupied and the number of sponge patches between surface angles and sites. Significantly lower (t > 4.61, df = 9, P < 0.001) sponge numbers, percentage cover and richness were associated with the reef flat at both sites compared with all other depths at each site, with the exception of abundance of sponges on the reef flat at Sampela, which was much greater than at any other depth sampled. Species richness increased with depth at both sites but differences between surface angles were only recorded at Sampela, with higher species richness being found on vertical, inclined and horizontal surfaces respectively A total of 100 sponge species (total area sampled 52.5 m(2)) was reported from the two sites, with 58 species found at Sampela and 71 species at Hoga (41% of species shared). Multi-dimensional scaling (MDS) indicated differences in assemblage structure between sites and most depth intervals, but not substratum angles. A number of biological (e.g. competition and predation) and physical (e.g. sedimentation and aerial exposure) factors were considered to control sponge abundance and richness. Unexpectedly a significant (F-1,F-169 = 148.98, P < 0.001) positive linear relationship was found between sponge density and area occupied. In areas of high sponge coverage, the number of patches was also high, possibly due to fragmentation of large sponges produced as a result of predation and physical disturbance. The MDS results were also the same whether sponge numbers or percentage cover estimates were used, suggesting that although these different approaches yield different sorts of information, the same assemblage structure can be identified.

Geographical distribution of the endemic Sardinian brook salamander, Euproctus platycephalus, and implications for its conservation

The Sardinian brook salamander, Euproctus platycephalus, is a cryptically coloured urodele found in streams, springs and pools in the main mountain systems of Sardinia, and is classified as critically endangered by IUCN. General reviews of the mountainous range where salamanders occur are numerous, but very few field-based distribution studies exist on this endemic species. Through a field and questionnaire survey, conducted between 1999 and 2001, we report a first attempt to increase data on the present distribution of E. platycephalus. A total of 14 localities where Sardinian salamanders are represented by apparently stable and in some cases abundant populations have been identified, as well as 30 sites where species presence has been recorded after 1991. Some 11 historical sites were identified which are no longer inhabited by the species. The implications of this distributional study for the conservation of the species and for the realization of an updated atlas are discussed.
