This chapter compares the trajectories of Glauber Rocha and Werner Herzog in the light of the Cinema Novo.

Além da diferença: a mulher no Cinema da Retomada

This paper analyses the female participation in the Brazilian Film Revival of the 1990s beyond differences of sex, race, class, age and ethnicity. Its main contention is that the most decisive contribution brought about by the rise of women in recent Brazilian cinema has been the spread of team work and shared authorship, as opposed to a mere aspiration to the auteur pantheon, as determined by a notoriously male-oriented tradition.

'Eden Cinema' by Marguerite Duras

Duras’s theatre work has been profoundly neglected by UK theatre academics and practitioners, and Eden Cinema has almost no performance history in Britain. My project asked three interconnected research questions: how developing the performance contributes to understanding Duras’s theatre and specifically Eden Cinema’s problems of performability; how multimedia performance emphasising mediated sound and the live body reconfigures memory, autobiography, storytelling, gender and racial identity; how to locate a performance style appropriate for Durasian narratives of displacement and death which reflect the discontinuous and mutable form of Duras’s ‘texte/film/théâtre’. Drawing on my research interests in gender, post-colonial hybridity and performed deconstruction, I focused my staging decisions on the discontinuities and ambivalences of the text. I addressed performability by avoiding the temptation to resolve the strange ellipses in the text and instead evoked the text’s imperfect and fragmented memories, and its uncertain spatial and temporal locations, by means of a fluid theatrical form. The mise-en-scène represented imagined and remembered spaces simultaneously, and co-existing historical moments. The performance style counterpointed live and mediated action and audio-visual forms. A complex through-composed soundscape, comprising voice-over, sound and music, became a key means for evoking overlapping temporalities, interconnected narratives and fragmented memories that were dispersed across the performance. The disempowerment of the mother figure and the silent indigenous servant in the text was demonstrated through their spatial centrality but physical stillness. The servant’s colonial subaltern identity was paralleled and linked with the mother’s disenfranchisement through their proxemic relationships. I elicited a performance style which evoked ‘characters’, whose being was deferred across different regimes of reality and who ‘haunted’ the stage rather than inhabited it. I developed the project further in the additional written outcomes and presentations, and the subsequent performance of Savannah Bay where problems of performability intensify until embodiment is almost erased except via voice.

Wearable device to assist independent living

Older people increasingly want to remain living independently in their own homes. The aim of the ENABLE project is to develop a wearable device that can be used to support older people in their daily lives and which can monitor their health status, detect potential problems, provide activity reminders and offer communication and alarm services. In order to determine the specifications and functionality required for the development of the device, user surveys and focus groups were undertaken, use case analysis and scenario modeling carried out. The project has resulted in the development of a wrist-worn device and mobile phone combination that can support and assist older and vulnerable wearers with a range of activities and services both inside their home and as they move around their local environment. The device is currently undergoing pilot trials in five European countries. The aim of this paper is to describe the ENABLE device, its features and services, and the infrastructure within which it operates.

Acute ingestion of beetroot bread increases endothelium-independent vasodilation and lowers diastolic blood pressure in healthy men: a randomized controlled trial

Dietary nitrate, from beetroot, has been reported to lower blood pressure (BP) by the sequential reduction of nitrate to nitrite and further to NO in the circulation. However, the impact of beetroot on microvascular vasodilation and arterial stiffness is unknown. In addition, beetroot is consumed by only 4.5% of the UK population, whereas bread is a staple component of the diet. Thus, we investigated the acute effects of beetroot bread (BB) on microvascular vasodilation, arterial stiffness, and BP in healthy participants. Twenty-three healthy men received 200 g bread containing 100 g beetroot (1.1 mmol nitrate) or 200 g control white bread (CB; 0 g beetroot, 0.01 mmol nitrate) in an acute, randomized, open-label, controlled crossover trial. The primary outcome was postprandial microvascular vasodilation measured by laser Doppler iontophoresis and the secondary outcomes were arterial stiffness measured by Pulse Wave Analysis and Velocity and ambulatory BP measured at regular intervals for a total period of 6 h. Plasma nitrate and nitrite were measured at regular intervals for a total period of 7 h. The incremental area under the curve (0-6 h after ingestion of bread) for endothelium-independent vasodilation was greater (P = 0.017) and lower for diastolic BP (DBP; P = 0.032) but not systolic (P = 0.99) BP after BB compared with CB. These effects occurred in conjunction with increases in plasma and urinary nitrate (P < 0.0001) and nitrite (P < 0.001). BB acutely increased endothelium-independent vasodilation and decreased DBP. Therefore, enriching bread with beetroot may be a suitable vehicle to increase intakes of cardioprotective beetroot in the diet and may provide new therapeutic perspectives in the management of hypertension.

A twenty-year independent record of sea surface temperature for climate from Along-track Scanning Radiometers

A new record of sea surface temperature (SST) for climate applications is described. This record provides independent corroboration of global variations estimated from SST measurements made in situ. Infrared imagery from Along-Track Scanning Radiometers (ATSRs) is used to create a 20 year time series of SST at 0.1° latitude-longitude resolution, in the ATSR Reprocessing for Climate (ARC) project. A very high degree of independence of in situ measurements is achieved via physics-based techniques. Skin SST and SST estimated for 20 cm depth are provided, with grid cell uncertainty estimates. Comparison with in situ data sets establishes that ARC SSTs generally have bias of order 0.1 K or smaller. The precision of the ARC SSTs is 0.14 K during 2003 to 2009, from three-way error analysis. Over the period 1994 to 2010, ARC SSTs are stable, with better than 95% confidence, to within 0.005 K yr−1(demonstrated for tropical regions). The data set appears useful for cleanly quantifying interannual variability in SST and major SST anomalies. The ARC SST global anomaly time series is compared to the in situ-based Hadley Centre SST data set version 3 (HadSST3). Within known uncertainties in bias adjustments applied to in situ measurements, the independent ARC record and HadSST3 present the same variations in global marine temperature since 1996. Since the in situ observing system evolved significantly in its mix of measurement platforms and techniques over this period, ARC SSTs provide an important corroboration that HadSST3 accurately represents recent variability and change in this essential climate variable.

Cannabidivarin-rich cannabis extracts are anticonvulsant in mouse and rat via a CB 1 receptor-independent mechanism

BACKGROUND AND PURPOSE Epilepsy is the most prevalent neurological disease and is characterized by recurrent seizures. Here, we investigate (i) the anticonvulsant profiles of cannabis-derived botanical drug substances (BDSs) rich in cannabidivarin (CBDV) and containing cannabidiol (CBD) in acute in vivo seizure models and (ii) the binding of CBDV BDSs and their components at cannabinoid CB 1 receptors. EXPERIMENTAL APPROACH The anticonvulsant profiles of two CBDV BDSs (50–422 mg·kg −1 ) were evaluated in three animal models of acute seizure. Purified CBDV and CBD were also evaluated in an isobolographic study to evaluate potential pharmacological interactions. CBDV BDS effects on motor function were also investigated using static beam and grip strength assays. Binding of CBDV BDSs to cannabinoid CB 1 receptors was evaluated using displacement binding assays. KEY RESULTS CBDV BDSs exerted significant anticonvulsant effects in the pentylenetetrazole (≥100 mg·kg −1 ) and audiogenic seizure models (≥87 mg·kg −1 ), and suppressed pilocarpine-induced convulsions (≥100 mg·kg −1 ). The isobolographic study revealed that the anticonvulsant effects of purified CBDV and CBD were linearly additive when co-administered. Some motor effects of CBDV BDSs were observed on static beam performance; no effects on grip strength were found. The Δ 9 -tetrahydrocannabinol and Δ 9 -tetrahydrocannabivarin content of CBDV BDS accounted for its greater affinity for CB 1 cannabinoid receptors than purified CBDV. CONCLUSIONS AND IMPLICATIONS CBDV BDSs exerted significant anticonvulsant effects in three models of seizure that were not mediated by the CB 1 cannabinoid receptor and were of comparable efficacy with purified CBDV. These findings strongly support the further clinical development of CBDV BDSs for the treatment of epilepsy.

Tempo, magnitude e o mito do cinema moderno

Neste texto, irei abordar três filmes ambientados em Portugal, cujas locações oferecem uma visão privilegiada da função do tempo e da magnitude no cinema, os quais, por sua vez, nos permitem reavaliar as categorias de clássico, moderno e pós-moderno aplicadas a esse meio. Trata-se de O estado das coisas (Der Stand der Dinge, Wim Wenders, 1982), Terra estrangeira (Walter Salles and Daniela Thomas, 1995) e Mistérios de Lisboa (Raúl Ruiz, 2010). Neles, a cidade se compõe de círculos viciosos, espelhos, réplicas e mise-en-abyme que interrompem o movimento vertiginoso característico da cidade modernista do cinema dos anos 20. Curiosamente, é também o lugar em que a assim chamada estética pós-moderna finalmente encontra abrigo em contos auto-irônicos que expõem as insuficiências dos mecanismos narrativos no cinema. Para compensá-las, recorre-se a procedimentos de intermídia, tais como fotografias de polaroid em O estado das coisas ou um teatro de papelão em Mistérios de Lisboa, que transformam uma realidade incomensurável em miniaturas fáceis de enquadrar e manipular. O real assim diminuído, no entanto, se revela um simulacro decepcionante, um ersatz da memória que evidencia o caráter ilusório da teleologia cosmopolita. Em minha abordagem, começarei por examinar a gênese interligada e transnacional desses filmes que resultou em três visões correlatas mas muito diversas do fim da história e da narrativa, típico da estética pós-moderna. A seguir, irei considerar o miniaturismo intermedial como uma tentativa de congelar o tempo no interior do movimento, uma equação que inevitavelmente nos remete ao binário deleuziano tempo-movimento, que também irei revisitar com o fim de distingui-lo da oposição entre cinema clássico e moderno. Por fim, irei propor a stasis reflexiva e a inversão de escala como demonominadores comuns entre todos os projetos ditos modernos, que por esta razão, segundo creio, são mais confiáveis que a modernidade enquanto indicadores de valores artísticos e políticos.
