Les Carr explains the moral high ground on open educational resources

In this video, taken in front of the Parthenon at the Acropolis in Athens, Su White interviews Les Carr about why he asserts that there is a moral duty for teachers who create educational content to put that content in the public domain, rather than hoarding it in their institution.

Under the ground.

Descubrimos en el interior de la Tierra un completo y nuevo mundo. Nuestro planeta no es una superficie estable, sino que sufre continuos cambios producidos en sus capas internas, a grandes profundidades y elevadas temperaturas. Bajo la superficie, se forman laberintos de cuevas y túneles subterráneos, que por efecto del agua sobre la piedra caliza,crean las estalagmitas y las estalactitas. En este mundo subterráneo viven animales, pero también algunos humanos. Los primeros habitantes del planeta habitaron en cuevas, y actualmente, en varias zonas del mundo, con climas extremos de frío o calor, algunas personas hacen sus vidas en construcciones por debajo de la tierra. En las ciudades se construyen túneles para que por ellos circulen trenes metropolitanos, y también se encuentran tuberías y distintos cableados.El interior de la Tierra es rico en recursos naturales: minerales, metales presciosos, gas, carbón, petróleo; pero tambien guarda objetos y tesoros arqueológicos del pasado de la humanidad.

SF e Animé : os Monstros Encantadores do Ground Zero

O fascínio do poder de dotar de vida ao que está inanimado talvez possa ajudar a revelar o encanto que sentimos quando os objectos fixos se começam a mover e a desenvolver coreografias cheias de vida. Na animé, a técnica do desenho tornou-se o processo ideal para explorar estes temas por ser mais fácil desenhar figuras monstruosas do que construir personagens, naves ou cenários futuristas para o cinema live-action. Após a II Grande Guerra, no momento inicial da reconstrução do Japão, o Ground Zero, coincide com o desenvolvimento de uma cultura pop na qual os desenhos manga e a animé se tornaram referências fundamentais. Iremos verificar como uma das importantes particularidades de séries de animação japonesa é a exploração de imaginários SF onde o atómico é encanto monstruoso, que se controla ou pelo qual se é controlado. Dando especial destaque às séries de televisão Prince Planet (Sato Okura, 1965), Gigantor (Mitsuteru Yokoyama, 1963) ou Astro Boy (Osamu Tezuka, 1963), iremos demonstrar que pela componente técnica ou visual da animação a animé é um modelo específico de estudo para tentar contextualizar a atracção humana por mundos controlados por máquinas, pela manipulação genética ou pela possibilidade de uma paisagem cyborg.

Predation in Ground-Nesting Birds: an Experimental Study Using Natural Egg-Color Variation

We tested the hypothesis that cryptically colored eggs would suffer less predation than conspicuous eggs in the ground-nesting red-legged partridge, Alectoris rufa. We used A. rufa as a model species because it has a wide range of natural egg colors, the eggs are widely available from breeding farms, and nests are easily mimicked because they are scrapes containing no vegetation. The study was conducted in the spring of 2001 in forest and fallow fields of central Spain in Castilla La Mancha, Ciudad Real. We used 384 clutches of natural eggs that were white, white spotted, brown, or brown spotted. Within clutches, eggs were consistent in color and size; among clutches, color differences were distributed across habitats. Clutches were checked once after 2 wk of exposure. Cryptic coloration had a survival advantage that was dependent on the local suite of predators. Rodent predation was nonselective with respect to clutch color; however, avian predation was significantly higher for conspicuous clutches. In addition, there was an interaction of landscape and egg color for avian predation. In forest landscapes, the clutches with highest survival were brown spotted, whereas in fallow landscapes, brown and brown spotted clutches had higher survival than white and white potted clutches. Thus, both the predator suite and the landscape had significant effects on the value of cryptic egg coloration. Our study is relevant for conservationists and managers in charge of restocking programs in hunting areas. The release of other partridge species or their hybrids could result in hybridization with wild partridges, potentially leading to nonoptimal clutch pigmentation and reduced survival of the native species. We therefore recommend that local authorities, managers, and conservationists be cautious with the use of alien species and hybrids and release only autochthonous species of partridges within their natural ranges.

Mapping the spatial distribution of geomorphological processes in the Okstindan area of northern Norway, using Geomorphic Process Units as derived from remote sensing and ground survey

The delineation of Geomorphic Process Units (GPUs) aims to quantify past, current and future geomorphological processes and the sediment flux associated with them. Five GPUs have been identified for the Okstindan area of northern Norway and these were derived from the combination of Landsat satellite imagery (TM and ETM+) with stereo aerial photographs (used to construct a Digital Elevation Model) and ground survey. The Okstindan study area is sub-arctic and mountainous and is dominated by glacial and periglacial processes. The GPUs exclude the glacial system (some 37% of the study area) and hence they are focussed upon periglacial and colluvial processes. The identified GPUs are: 1. solifluction and rill erosion; 2. talus creep, slope wash and rill erosion; 3. accumulation of debris by rock and boulder fall; 4. rockwalls; and 5. stable ground with dissolved transport. The GPUs have been applied to a ‘test site’ within the study area in order to illustrate their potential for mapping the spatial distribution of geomorphological processes. The test site within the study area is a catchment which is representative of the range of geomorphological processes identified.
