El papel de los carteles de la División de Gráfica y Cine de Parques y Recreo Público en la redefinición colonial del Puerto Rico de mediados del siglo XX

El cartel serigráfico del proyecto de carteles del Taller de Cinema y Gráfica de Parques y Recreo Público se utilizó como medio para educar e insertar a las grandes masas dentro de las reformas coloniales ocurridas como consecuencia de la entrada de Estados Unidos a la Segunda Guerra Mundial y readiestrar a la población puertorriqueña, entonces compuesta por campesinos, para servir como mano de obra barata y dócil al proyecto colonial y a los beneficiarios del proyecto de industrialización de la posguerra. Se ha dicho en innumerables ocasiones que el camino al infierno está repleto de buenas intenciones; este es el relato de un viaje de ida. Los carteles de la División de Cinema y Gráfica de Parques y Recreo Público mantienen desde el origen varios elementos inquietantes de lo que se podría denominar como la política de reconstrucción de una colonia, de un territorio objeto de la sujeción/subyugación por parte de otro país, y presentarlo como un objetivo plausible, de consideración y cumplimiento con los derechos humanos fundamentales...

Trata-se de uma pesquisa qualitativa, histórica com revisao de literatura em Língua Portuguesa. Dentre muitos serviços à populaçao, Mário de Andrade, Secretário da Cultura do Município de Sao Paulo, e escritor de Pauliceia Desvairada, idealizou e implementou os Parques Infantis para crianças e jovens paulistanos. Os Parques Infantis educavam seusfrequentadores de forma plena; os serviços ali prestados incluindo - o médico odontológicos - representavam mais que um atendimento aos abandonados aprópria sorte.

Compilation of organic carbon distribution and sedimentology in the surface sediments on the continental margin offshore southwestern Africa

In this study we demonstrate the relevance of lateral particle transport in nepheloid layers for organic carbon (OC) accumulation and burial across high-productive continental margins. We present geochemical data from surface sediments and suspended particles in the bottom nepheloid layer (BNL) from the most productive coastal upwelling area of the modern ocean, the Benguela upwelling system offshore southwest Africa. Interpretation of depositional patterns and comparison of downslope trends in OC content, organic matter composition, and 14C age between suspended particles and surface sediments indicate that lateral particle transport is the primary mechanism controlling supply and burial of OC. We propose that effective seaward particle transport primarily along the BNL is a key process that promotes and maintains local high sedimentation rates, ultimately causing high preservation of OC in a depocenter on the upper slope offshore Namibia. As lateral transport efficiently displaces areas of enhanced OC burial from maximum production at highly productive continental margins, vertical particle flux models do not sufficiently explain the relationship between primary production and shallow-marine OC burial. On geologic time scales, the widest distribution and strongest intensity of lateral particle transport is expected during periods of rapid sea-level change. At times in the geologic past, widespread downslope lateral transport of OC thus may have been a primary driver of enhanced OC burial at deeper continental slopes and abyssal basins.

Directional wave measurements using the Offshore Sensing Sailbuoy, link to MATLAB file

An autonomous vessel, the Offshore Sensing Sailbuoy, was used for wave measurements near the Ekofisk oil platform complex in the North Sea (56.5 N, 3.2 E, operated by ConocoPhilllips) from 6 to 20 November 2015. Being 100% wind propelled, the Sailbuoy has two-way communication via the Iridium network and has the capability for missions of six months or more. It has previously been deployed in the Arctic, Norwegian Sea and the Gulf of Mexico, but this was the first real test for wave measurements. During the campaign it held position about 20km northeast of Ekofisk (on the lee side) during rough conditions. Mean wind speed measured at Ekofisk during the campaign was near 9.8m/s, with a maximum of 20.4m/s, with wind mostly from south and south west. A Datawell MOSE G1000 GPS based 2Hz wave sensor was mounted on the Sailbuoy. Mean significant wave height (Hs 1hr) measured was 3m, whereas maximum Hs was 6m. Mean wave period was 7.7s, while maximum wave height, Hmax, was 12.6m. These measurements have been compared with non-directional Waverider observations at the Ekofisk complex. Mean Hs at Ekofisk was 3.1m, while maximum Hs was 6.5m. Nevertheless, the correlation between the two measurements was high (97%). Spectra comparison was also good, except for low Hs (~1m), where the motion of the vessel seemed to influence the measurements. Nevertheless, the Sailbuoy performed well during this campaign, and results suggests that it is a suitable platform for wave measurements in rather rough sea conditions.

Unstructured grid modelling of offshore wind farm impacts on seasonally stratified shelf seas

Shelf seas comprise approximately 7% of the world’s oceans and host enormous economic activity. Development of energy installations (e.g. Offshore Wind Farms (OWFs), tidal turbines) in response to increased demand for renewable energy requires a careful analysis of potential impacts. Recent remote sensing observations have identified kilometrescale impacts from OWFs. Existing modelling evaluating monopile impacts has fallen into two camps: small-scale models with individually resolved turbines looking at local effects; and large-scale analyses but with sub-grid scale turbine parameterisations. This work straddles both scales through a 3D unstructured grid model (FVCOM): wind turbine monopiles in the eastern Irish Sea are explicitly described in the grid whilst the overall grid domain covers the south-western UK shelf. Localised regions of decreased velocity extend up to 250 times the monopile diameter away from the monopile. Shelf-wide, the amplitude of the M2 tidal constituent increases by up to 7%. The turbines enhance localised vertical mixing which decreases seasonal stratification. The spatial extent of this extends well beyond the turbines into the surrounding seas. With significant expansion of OWFs on continental shelves, this work highlights the importance of how OWFs may impact coastal (e.g. increased flooding risk) and offshore (e.g. stratification and nutrient cycling) areas.

Abordagem teórica dos condicionantes da formação e consolidação dos parques tecnológicos

O artigo discute as condições teóricas para a instalação e consolidação dos parques tecnológicos, mecanismos utilizados na promoção da inovação tecnológica e do desenvolvimento regional, alvo de diversas iniciativas de políticas públicas na atualidade. Para a consecução desse objetivo foi adotada uma abordagem teórica e exploratória, por meio de revisão bibliográfica, em especial de referências internacionais. O artigo apresenta e analisa diversos conceitos e definições de parque tecnológico e constata que essa diversidade decorre das diferentes realidades regionais e das variadas motivações dos stakeholders. O papel dos parques tecnológicos no desenvolvimento regional assume múltiplas feições em decorrência dos distintos interesses dos atores envolvidos em sua instalação. O artigo enfatiza e adverte que há importantes limitações da ideia de que o sucesso do parque depende fundamentalmente da capacidade de cooperação e mobilização de recursos por parte dos agentes envolvidos.
