Care of the Self, Care of the Earth: A new conversation for Rio+20

What if capitalism, understood as an economic, social and cultural complex, was on the agenda of a world summit on sustainable development? How has the culture of capitalism - its psychic investment in colonizing our attention - compromised our ability to respond meaningfully to the challenges of sustainable development? These are two of the questions behind this exploration of the constraints that appear to limit the scope of economic debate at conferences such as the Rio+20 conference

Speculative Return Address Stack Management Revisited

Branch prediction feeds a speculative execution processor core with instructions. Branch mispredictions are inevitable and have negative effects on performance and energy consumption. With the advent of highly accurate conditional branch predictors, nonconditional branch instructions are gaining importance.

Plus ça change: (Post)Colonial Timor-Leste as a Return to (Pre)Colonial Realities in the Novels of Luis Cardoso

This article examines the novels of the East Timorese writer Luís Cardoso, and argues that their representations of a colonial past should not be simply interpreted as memorializations of Timor-Leste’s suffering at the hands of foreign aggressors. It proposes that underlying their revisiting of the past is a call for acknowledgement of the agency of East Timorese in the history of violent conflict that has troubled the nation, and that only this can guarantee true reconciliation, justice and national independence.

Living in Exospace: ISS and Discovery 1

The concept of exospace, as an alternative liveable structure, is discussed in this article to improve our comprehension of architectural space. Exospace is a man-made space designed for living beyond Earth’s atmosphere. Humankind has developed outerspace technologies to build the International Space Station as a significant experiment in exospace design. The ISS is a new building type for scientific experiments and for testing human existence in outerspace.

A fictional example of exospace, on the other hand, is Discovery 1 spaceship in Stanley Kubrick’s legendary science fiction film 2001: A Space Odyssey (1968). It is a ship travelling to Jupiter with a crew of five astronauts and HAL9000, the artificial intelligence controlling the ship. I will first discuss the ISS, and the space stations built before, from a spatial point of view. A spatial study of Discovery 1 will follow. Finally, through an understanding of exospace, I will return to architectural space with a critical appraisal. The comparison of architectural space with exospace will add to the discussion of space theories from a technological approach.

Exospace creates an alternative reality to architectural space. Architects cannot consider exospaces without comparing them with the spaces they design on Earth. The different context of outerspace shows that a work of terrestrial architecture is very much dependent on its context. A building is not an ‘object’ that can be located anywhere; it is designed for its site. Architectural space is a real, material, continuous, static and extroverted habitable space designed for and used in the specific physical context of Earth. The existence of exospace in science opens a new discussion in architectural theory, both terrestrial and extraterrestrial.

Realizing a high magnetic moment in Gd/Cr/FeCo: The role of the rare earth

The search for materials or systems exhibiting a high magnetic saturation has been of longstanding importance. It has been suggested that increased saturation could be achieved by coupling a transition metal via a spacer to a rare earth. We report Gd/Cr/Fe₇₀Co₃₀ multilayer stacks and find reduced yet modulating magnetic moment as a function of Cr thickness. Through a micro structural analysis the lowered moment is indicated by the nucleation of the ultrathin Gd films into an fcc phase. We discuss the possible solution in terms of quasi-perfect lattice match seed material to promote growth of hcp Gd.

From Frank Miller to Zack Snyder, and Return: Contemporary Superhero Comics and Post-Classical Hollywood

Film adaptations of superhero comic-books offer a particularly rich case study to analyse narrative strategies of contemporary Hollywood cinema. The serial structures adopted by the comics they are based on, as well as their use of the spectacular potential of the image, provide a successful model for current audiovisual productions. Without completely abandoning classical techniques, these adaptations try to find a new balance between narrative and digital phantasmagoria. This paper discusses some significant examples of this genre, including adaptations of classical DC and Marvel franchises and more recent series, as well as other comic-book influenced films such as The Matrix and Unbreakable.

Is the number of species on earth increasing or decreasing? Time, chaos and the origin of species

Darwin's On the Origin of Species has led to a theory of evolution with a mass of empirical detail on population genetics below species level, together with heated debate on the details of macroevolutionary patterns above species level. Most of the main principles are clear and generally accepted, notably that life originated once and has evolved over time by descent with modification. Here, I review the fossil and molecular phylogenetic records of the response of life on Earth to Quaternary climatic changes. I suggest that the record can be best understood in terms of the nonlinear dynamics of the relationship between genotype and phenotype, and between climate and environments. 'The origin of species' is essentially unpredictable, but is nevertheless an inevitable consequence of the way that organisms reproduce through time. The process is 'chaotic', but not 'random'. I suggest that biodiversity is best considered as continuously branching systems of lineages, where 'species' are the branch tips. The Earth's biodiversity should thus (1) be in a state of continuous increase and (2) show continuous discrepancies between genetic and morphological data in time and space. © The Palaeontological Association.
