The Prohibition against Torture: Why the UK Government is Falling Short and the Risks that Remain
While the UK's official position is that it neither uses nor condones torture or cruel, inhuman and degrading treatment (CIDT), it is now a matter of public and parliamentary record that UK security services and military personnel colluded in rendition, torture, and cruel, inhuman and degrading treatment, both as part of the CIA's Rendition, Detention and Interrogation (RDI) programme, at military detention facilities in Afghanistan and Iraq, and through involvement in the detention and interrogation of prisoners by allied security forces. This paper will explain why the government is falling short of its obligations under international law, and why considerable risks remain that UK intelligence and security services will continue to collude in torture and CIDT
Human Rights Fact-Finding and the CIA's Rendition, Detention and Interrogation Programme: A Response to Cordell
In her article, ‘Measuring extraordinary rendition and international cooperation’, Rebecca Cordell seeks to subject the Rendition Flights Database to a model-based, statistical analysis. She argues that her analysis suggests that more countries were involved in the CIA’s rendition programme than our work has previously established, and that many more flights in the database are likely to be connected to rendition operations than we have identified. While we would not dispute the likelihood that both of these statements are correct, and we have always presented our findings with an acknowledgement that they provide a necessarily limited account of the rendition, detention and interrogation (RDI) programme, we suggest that Cordell’s work should be approached with some caution. This is so for two reasons. First, her findings – although derived through a different mode of analysis from our own – do not appear to move beyond those we have already published. Second, because Cordell has not triangulated her analysis with either data relating to transfers of specific prisoners, or with evidence relating to which countries hosted prisons for the CIA and the operational dates for these prisons, we question her claim that the flights she has identified from the Database are ‘likely rendition flights’. We aim to demonstrate the importance of having a clear understanding of the limitations of big data when researching violations of human rights, especially where such data is related to covert operations. We also seek to show why the Renditions Flights Database only has merit when it is triangulated with a wide range of supplementary sources, including first-hand accounts by prisoners themselves, declassified documents from the US Government, and the findings of parliamentary, journalist and legal investigations. It is this process of triangulation which gives the flight data meaning and which makes it of value for establishing the facts of human rights abuses
Tracking rendition aircraft as a way to understand CIA secret detention and torture in Europe
We examine how the tracking of rendition aircraft has provided a much fuller understanding of the CIA’s rendition, detention and interrogation programme. In particular, we show how this illuminated the role played by European states. Through various investigative methods, new rendition aircraft were identified, significant amounts of flight data were gathered, and data on all known and suspected rendition flights were collated into one public, searchable database. We show that examining logistical elements of covert programmes can prove fruitful for security and human rights research. Furthermore, we demonstrate the benefits of close academic-practitioner collaboration in the field of human rights
The Persistence of Union Membership in the Coalfields of Britain
Spatial variance in union membership has been attributed to the favourable attitudes that persist in areas with an historical legacy of trade unionism. Within the United Kingdom, villages and towns located in areas once dominated by coalmining remain among the strongest and most durable bases for the trade union movement. This article empirically examines the effect of living within or near these areas upon union membership. Those residing in ex-mining areas retain an increased propensity for union membership. However, this effect diminishes sharply with distance. The analysis reveals that particular places can serve as conduits of trade unionism, long after employment within traditional industries has vanished

Performance of Willamette Valley native plants following herbicide exposure
Prairies were once the dominant vegetation type in Oregon's Willamette Valley. Land use conversion, fire suppression, succession, and invasive species have reduced Willamette Valley prairies to less than 1% of their historical area. The remnant prairies that persist today are small in size and are highly fragmented. Marginal strips of habitat along roadsides and agricultural fields play an important role as refugia for native species and provide important resources for wildlife. These seemingly insignificant habitat units may also play an important role in facilitating gene flow between disjunct populations of prairie plants, thus reducing the potential for the negative effects of inbreeding depression. Presently, much of the land area in the Willamette Valley is dedicated to commercial agricultural which is heavily reliant on herbicides for weed control and field preparation. Since herbicide applications are imprecise and prone to drift, there is potential to impact the native plants surrounding these agricultural fields. Current EPA methods for assessing the ecological effects of herbicides may not be robust enough to account for potential impacts on native plants since the suggested test species are ten annual agricultural crops. To address the need for improved phytotoxicity testing protocols, we incorporated non-crop plant species into the EPA vegetative vigor test methodology for use in determining effects of low concentrations of chemical herbicides on Willamette Valley terrestrial plants. A separate experiment was conducted in order to determine how herbicides might be used to restore Butterfly Meadows, a degraded Willamette Valley prairie. The specific objective of this study were to: 1.) determine which herbicide treatments were most effective at reducing dominance of an invasive species, Brachypodium sylvaticum, 2.) determine if native species declined following herbicide treatments, and 3.) describe the compositional changes in the plant communities over a four-year period. The EPA vegetative vigor test study showed that there was a wide variety of responses among 17 species (14 native and 3 introduced) to each herbicide tested (glyphosate, tribenuron, and fluazifop). For glyphosate, Potentilla gracilis was the most sensitive species based on an EC25 value of 0.012 x f.a.r. for dry weight; while Bromus carinatus, Clarkia amoena, Gilia capitata, and Lupinus albicaulis were tolerant to glyphosate as indicated by no effect on dry weight. Seven Willamette Valley forb species were sensitive to tribenuron based on EC25 values ranging from 0.001 to 0.012 x f.a.r.; Clarkia amoena, Collinsia grandflora, Leucanthemum vulgare, Potentilla gracilis, Prunella vulgaris, Ranunculus occidentalis and Sanquisorba occidentalis. Six grass species and Eriophyllum lanatum were resistant to tribenuron showing no reduction in dry weight. Fluazifop primarily affected grass species as expected due to the grass-specific activity for this herbicide. Two native grasses, Elymus trachycaulus and Danthonia californica were the most sensitive to fluazifop, based on low EC25 values of 0.002 to 0.010 x f.a.r. A native fescue grass, Festuca roemeri, and nearly all the forb species were resistant to fluazifop, showing no response at any herbicide rate applied. The results from this research will be useful as background information for evaluating potential modifications in the EPA's Vegetative Vigor Test to assess the risk of herbicides to non-target plants. Seven different herbicide combinations were effective at reducing the cover of Brachypodium sylvaticum in test plots at Butterfly Meadows one year after treatment. The reduction of B. sylvaticum was short lived however, since the cover of this grass species was not different from control plots during the second growing season. Native plant species were not negatively impacted by the herbicide treatments, as shown by MRPP analysis. Successional trajectories illustrate that control plots that were dominated by B. sylvaticum remained relatively unchanged over the course of four years. Some treatments exhibited a sharp decline in dominance by graminoids after the first year, a recovery the second year, but never returned exactly to their pretreatment community composition after the third year. The reduction of the dominant species after the first growing season was associated with colonization by a number of introduced species into the newly created open habitat. Over the same period there was no overall increase in native species cover, suggesting that the native species at this site may be recruitment limited. Future restoration activities at this site should include multiple years of B. sylvaticum control, with special attention to the seed bank and tolerant individuals. Seed additions of native species may help fill empty niches and afford resistance to invasion by introduced species
Scaling up index insurance for smallholder farmers: Recent evidence and insights
This report explores evidence and insights from five case studies that have made significant recent progress in addressing the challenge of insuring poor smallholder farmers and pastoralists in the developing world. In India, national index insurance programmes have reached over 30 million farmers through a mandatory link with agricultural credit and strong government support. In East Africa (Kenya, Rwanda and Tanzania), the Agriculture and Climate Risk Enterprise (ACRE) has recently scaled to reach nearly 200,000 farmers, bundling index insurance with agricultural credit and farm inputs. ACRE has built on strong partnerships with regional initiatives such as M-PESA mobile banking. In Ethiopia and Senegal, the R4 Rural Resilience Initiative has scaled unsubsidized index insurance to over 20,000 poor smallholder farmers who were previously considered uninsurable, using insurance as an integral part of a comprehensive risk management portfolio. With strong public and private sector support, the Mongolia Index-Based Livestock Insurance Project (IBLIP) insures more than 15,000 nomadic herders and links commercial insurance with a government disaster safety net. Finally, the Index-Based Livestock Insurance (IBLI) project in Kenya and Ethiopia demonstrates innovative approaches to insuring poor nomadic pastoralists in challenging circumstances.
A few common features appear to have contributed to recent progress within these case studies:
explicitly targeting obstacles to improving farmer income;
integration of insurance with other development interventions;
giving farmers a voice in the design of products;
investing in local capacity; and
investing in science-based index development.
Evidence from these case studies can inform the ongoing debate about the viability of scaling up index-based insurance for vulnerable smallholder farmers in the developing world. The rapid progress observed in recent years suggests that index insurance has the potential to benefit smallholder farmers at a meaningful scale, and suggests the need to reassess arguments that lack of demand and practical implementation challenges prevent index-based insurance from being a useful tool to reduce rural poverty
Development of an Electrostatic Precipitator to Remove Martian Atmospheric Dust from ISRU Gas Intakes During Planetary Exploration Missions
Manned exploration missions to Mars will need dependable in situ resource utilization (ISRU) for the production of oxygen and other commodities. One of these resources is the Martian atmosphere itself, which is composed of carbon dioxide (95.3%), nitrogen (2.7%), argon (1.6%), oxygen (0.13%), carbon monoxide (0.07%), and water vapor (0.03%), as well as other trace gases. However, the Martian atmosphere also contains relatively large amounts of dust, uploaded by frequent dust devils and high Winds. To make this gas usable for oxygen extraction in specialized chambers requires the removal of most of the dust. An electrostatic precipitator (ESP) system is an obvious choice. But with an atmospheric pressure just one-hundredth of Earth's, electrical breakdown at low voltages makes the implementation of the electrostatic precipitator technology very challenging. Ion mobility, drag forces, dust particle charging, and migration velocity are also affected because the low gas pressure results in molecular mean free paths that are approximately one hundred times longer than those at Earth .atmospheric pressure. We report here on our efforts to develop this technology at the Kennedy Space Center, using gases with approximately the same composition as the Martian atmosphere in a vacuum chamber at 9 mbars, the atmospheric pressure on Mars. We also present I-V curves and large particle charging data for various versions of wire-cylinder and rod-cylinder geometry ESPs. Preliminary results suggest that use of an ESP for dust collection on Mars may be feasible, but further testing with Martian dust simulant is required
Self-organization of the in vitro attached human embryo
Implantation of the blastocyst is a developmental milestone in mammalian embryonic development. At this time, a coordinated program of lineage diversification, cell-fate specification, and morphogenetic movements establishes the generation of extra-embryonic tissues and the embryo proper, and determines the conditions for successful pregnancy and gastrulation. Despite its basic and clinical importance, this process remains mysterious in humans. Here we report the use of a novel in vitro system1,2 to study the post-implantation development of the human embryo. We unveil the self-organizing abilities and autonomy of in vitro attached human embryos. We find human-specific molecular signatures of early cell lineage, timing, and architecture. Embryos display key landmarks of normal development, including epiblast expansion, lineage segregation, bi-laminar disc formation, amniotic and yolk sac cavitation, and trophoblast diversification. Our findings highlight the species-specificity of these developmental events and provide a new understanding of early human embryonic development beyond the blastocyst stage. In addition, our study establishes a new model system relevant to early human pregnancy loss. Finally, our work will also assist in the rational design of differentiation protocols of human embryonic stem cells to specific cell types for disease modelling and cell replacement therapy
Urgent Considerations for the Neuro-oncologic Treatment of Patients with Gliomas During the COVID-19 Pandemic.
The COVID-19 outbreak is posing unprecedented risks and challenges for all communities and healthcare systems, worldwide. There are unique considerations for many adult patients with gliomas who are vulnerable to the novel coronavirus due to older age and immunosuppression. As patients with terminal illnesses, they present ethical challenges for centers that may need to ration access to ventilator care due to insufficient critical care capacity. It is urgent for the neuro-oncology community to develop a pro-active and coordinated approach to the care of adults with gliomas in order to provide them with the best possible oncologic care while also reducing their risk of viral infection during times of potential healthcare system failure. In this article, we present an approach developed by an international multi-disciplinary group to optimize the care of adults with gliomas during this pandemic. We recommend measures to promote strict social distancing and minimize exposures for patients, address risk and benefit of all therapeutic interventions, pro-actively develop end of life plans, educate patients and caregivers and ensure the health of the multi-disciplinary neuro-oncology workforce. This pandemic is already changing neuro-oncologic care delivery around the globe. It is important to highlight opportunities to maximize the benefit and minimize the risk of glioma management during this pandemic and potentially, in the future
