The day Londres 38 opened its doors: a milestone in chilean reconciliation

Occasionally a week, an afternoon, a single moment may crystallise a traumatic event which has carried explosive potential for decades. At such still points shifting polarities may stabilise, if briefly. Old foes may unite, old friendships fracture. By the end of such a day, though, it will be apparent that something momentous has occurred from which there can be no retreat. This paper considers such an event, which should remain here occurred in Santiago de Chile, on December 10, 2007. That day, the infamous torture and extermination centre known as Londres 38 was for the first time opened to the public. But by the end of that day, much more had been exposed than the echoing and empty rooms

Memory and a Hard Place: Revisiting Central Havana

Raul and Manolo are two Cuban men in their late sixties. Manolo left soon after Castros triumph to become a television celebrity in Miami. He returned in 1991 to make a clandestine film about the city which once was his. Raul never left his decaying city. He applauded the revolution, but little by little his enthusiasm soured. The paper examines the relationship of the two men to what was once the ultra modern Central Havana of the mid-1950s. Manolos froze on the day he left: his filmed city is silent, immobile, full of ghosts, almost empty, ugly, ruined. Manolos Central Havana processes and changes, it is noisy, busy, - but also it is ugly and ruined. Both lament the city as it once was. Only Raul sees hope of reconciliatio

Narrow but endlessly deep

On 11 September 1973, the Chilean Chief of the Armed Forces Augusto Pinochet overthrew the Popular Unity government of Salvador Allende and installed a military dictatorship. Yet this is a book not of parties or ideologies but public history. It focuses on the memorials and memorialisers at seven sites of torture, extermination, and disappearance in Santiago, engaging with worldwide debates about why and how deeds of violence inflicted by the state on its own citizens should be remembered, and by whom. The sites investigated — including the infamous National Stadium — are among the most iconic of more than 1,000 such sites throughout the country. The study grants a glimpse of the depth of feeling that survivors and the families of the detained-disappeared and the politically executed bring to each of the sites. The book traces their struggle to memorialise each one, and so unfolds their idealism and hope, courage and frustration, their hatred, excitement, resentment, sadness, fear, division and disillusionment. ‘This is a beautifully written book, a sensitive treatment of the issues and lives of those who have faced a great deal of loss, most often as unsung heroes, in what are now recognized as Chilean sites of memory. The book is a testament to people who have not been asked to speak, until Peter Read and Marivic Wyndham ask them to tell their stories. They do not shy away from hard tensions about memorialization, the difficulties of challenging a powerful state and the long and arduous struggles to ensure less powerful voices are heard.

Sin Descansar, En Mi Memoria

This is a revised and extended Spanish version of Narrow But Endlessly Deep. A year has passed since the English version of our book Narrow but Endlessly Deep. The Struggle for Memorialisation in Chile since the Transition to Democracy was published. Since then, developments in certain sites have advanced well beyond the original story and much new information has emerged from various important sources. Equally importantly, our interpretations of certain events and personalities have changed in the light of the new revelations. This is why we have substantially re-written each chapter and given a new title to this book. Having to address Spanish-speaking readers has also necessitated a critical re-evaluation of the material which in some cases, though it may be ‘new’ and ‘interesting’ to English-speaking readers, constitutes basic knowledge for those born and bred in Hispanic cultures. As a result of these considerable changes and transformations, and the additions of new material not included in the English version, this Spanish–language text far exceeds a mere translation, and thus circulates as a distinct work of new historical critique and knowledge in its own right

Effects of footwear variations on three-dimensional kinematics and tibial accelerations of specific movements in American football

American football is associated with a high rate of non-contact chronic injuries. Players are able to select from both high and low cut footwear. The aim of the current investigation was to examine the influence of high and low cut American football specific footwear on tibial accelerations and three-dimensional (3D) kinematics during three sport specific movements. Twelve male American football players performed three movements, run, cut and vertical jump whilst wearing both low and high cut footwear. 3D kinematics of the lower extremities were measured using an eight-camera motion analysis system alongside tibial acceleration parameters which were obtained using a shank mounted accelerometer. Tibial acceleration and 3D kinematic differences between the different footwear were examined using either repeated measures or Friedman’s ANOVA. Tibial accelerations were significantly greater in the low cut footwear in comparison to the high cut footwear for the run and cut movements. In addition, peak ankle eversion and tibial internal rotation parameters were shown to be significantly greater in the low cut footwear in the running and cutting movement conditions. The current study indicates that the utilization of low cut American football footwear for training/performance may place American footballers at increased risk from chronic injuries

Composite Fermion Metals from Dyon Black Holes and S-Duality

We propose that string theory in the background of dyon black holes in four-dimensional anti-de Sitter spacetime is holographic dual to conformally invariant composite Dirac fermion metal. By utilizing S-duality map, we show that thermodynamic and transport properties of the black hole match with those of composite fermion metal, exhibiting Fermi liquid-like. Built upon Dirac-Schwinger-Zwanziger quantization condition, we argue that turning on magnetic charges to electric black hole along the orbit of Gamma(2) subgroup of SL(2,Z) is equivalent to attaching even unit of statistical flux quanta to constituent fermions. Being at metallic point, the statistical magnetic flux is interlocked to the background magnetic field. We find supporting evidences for proposed holographic duality from study of internal energy of black hole and probe bulk fermion motion in black hole background. They show good agreement with ground-state energy of composite fermion metal in Thomas-Fermi approximation and cyclotron motion of a constituent or composite fermion excitation near Fermi-point.Comment: 30 pages, v2. 1 figure added, minor typos corrected; v3. revised version to be published in JHE

Reduction of circulating cholesterol and apolipoprotein levels during sepsis

Sepsis with multiple organ failure is frequently associated with a substantial decrease of cholesterol levels. This decrease of cholesterol is strongly associated with mortality suggesting a direct relation between inflammatory conditions and altered cholesterol homeostasis. The host response during sepsis is mediated by cytokines and growth factors, which are capable of influencing lipid metabolism. Conversely lipoproteins are also capable of modulating cytokine production during the inflammatory response. Therefore the decrease in circulating cholesterol levels seems to play a crucial role in the pathophysiology of sepsis. In this review the interaction between cytokines and lipid metabolism and its clinical consequences will be discussed

Immune-mediated competition in rodent malaria is most likely caused by induced changes in innate immune clearance of merozoites

Malarial infections are often genetically diverse, leading to competitive interactions between parasites. A quantitative understanding of the competition between strains is essential to understand a wide range of issues, including the evolution of virulence and drug resistance. In this study, we use dynamical-model based Bayesian inference to investigate the cause of competitive suppression of an avirulent clone of Plasmodium chabaudi (AS) by a virulent clone (AJ) in immuno-deficient and competent mice. We test whether competitive suppression is caused by clone-specific differences in one or more of the following processes: adaptive immune clearance of merozoites and parasitised red blood cells (RBCs), background loss of merozoites and parasitised RBCs, RBC age preference, RBC infection rate, burst size, and within-RBC interference. These processes were parameterised in dynamical mathematical models and fitted to experimental data. We found that just one parameter μ, the ratio of background loss rate of merozoites to invasion rate of mature RBCs, needed to be clone-specific to predict the data. Interestingly, μ was found to be the same for both clones in single-clone infections, but different between the clones in mixed infections. The size of this difference was largest in immuno-competent mice and smallest in immuno-deficient mice. This explains why competitive suppression was alleviated in immuno-deficient mice. We found that competitive suppression acts early in infection, even before the day of peak parasitaemia. These results lead us to argue that the innate immune response clearing merozoites is the most likely, but not necessarily the only, mediator of competitive interactions between virulent and avirulent clones. Moreover, in mixed infections we predict there to be an interaction between the clones and the innate immune response which induces changes in the strength of its clearance of merozoites. What this interaction is unknown, but future refinement of the model, challenged with other datasets, may lead to its discovery

Evidence for a fractional quantum Hall state with anisotropic longitudinal transport

At high magnetic fields, where the Fermi level lies in the N=0 lowest Landau level (LL), a clean two-dimensional electron system (2DES) exhibits numerous incompressible liquid phases which display the fractional quantized Hall effect (FQHE) (Das Sarma and Pinczuk, 1997). These liquid phases do not break rotational symmetry, exhibiting resistivities which are isotropic in the plane. In contrast, at lower fields, when the Fermi level lies in the $N\ge2$ third and several higher LLs, the 2DES displays a distinctly different class of collective states. In particular, near half filling of these high LLs the 2DES exhibits a strongly anisotropic longitudinal resistance at low temperatures (Lilly et al., 1999; Du et al., 1999). These "stripe" phases, which do not exhibit the quantized Hall effect, resemble nematic liquid crystals, possessing broken rotational symmetry and orientational order (Koulakov et al., 1996; Fogler et al., 1996; Moessner and Chalker, 1996; Fradkin and Kivelson, 1999; Fradkin et al, 2010). Here we report a surprising new observation: An electronic configuration in the N=1 second LL whose resistivity tensor simultaneously displays a robust fractionally quantized Hall plateau and a strongly anisotropic longitudinal resistance resembling that of the stripe phases.Comment: Nature Physics, (2011

Antecedents and consequences of effectuation and causation in the international new venture creation process

The selection of the entry mode in an international market is of key importance for the venture. A process-based perspective on entry mode selection can add to the International Business and International Entrepreneurship literature. Framing the international market entry as an entrepreneurial process, this paper analyzes the antecedents and consequences of causation and effectuation in the entry mode selection. For the analysis, regression-based techniques were used on a sample of 65 gazelles. The results indicate that experienced entrepreneurs tend to apply effectuation rather than causation, while uncertainty does not have a systematic influence. Entrepreneurs using causation-based international new venture creation processes tend to engage in export-type entry modes, while effectuation-based international new venture creation processes do not predetermine the entry mod
