Safety Evaluation of Ultraviolet-Activated Fluorescent Roadway, Delineation: Preliminary Field Experiment
DTFH61-95-R-00093A new technology is being developed in Sweden to improve visibility for nighttime driving. This technology consists of Ultraviolet (UV) headlights in combination with fluorescent traffic control devices. Vehicles will be equipped with headlamps that supply UV radiation in a high-beam pattern, along with conventional halogen or metal halide low-beam headlamps. UV light is not visible to the human observer, but after striking certain materials it will cause them to "fluoresce", that is, the UV radiation is converted to longer wavelength, visible light. UV-activated fluorescent materials can be incorporated into roadway delineation, such as pavement markings. A field test was conducted to examine the effectiveness of using UV headlights, with fluorescent pavement markings, in increasing the visibility of roadway delineation. This included measurement of both a visibility distance and subjective ratings. The study examined drivers opinions of the UV light as well as measured distance and general visibility of the fluorescent roadway markings as compared to standard roadway markings. Results showed that UV headlights provided a significant increase in UV-activated fluorescent pavement marking delineation visibility
British Torture in the 'War on Terror'
Despite longstanding allegations of UK involvement in prisoner abuse during counterterrorism operations as part of the US-led ‘war on terror’, a consistent narrative emanating from British government officials is that Britain neither uses, condones nor facilitates torture or other cruel, inhuman, degrading treatment and punishment. We argue that such denials are untenable. We have established beyond reasonable doubt that Britain has been deeply involved in post-9/11 prisoner abuse, and we can now provide the most detailed account to date of the depth of this involvement. We argue that it is possible to identify a peculiarly British approach to torture in the ‘war on terror’, which is particularly well-suited to sustaining a narrative of denial. To explain the nature of UK involvement, we argue that it can be best understood within the context of how law and sovereign power have come to operate during the ‘war on terror’. We turn here to the work of Judith Butler, and explore the role of Britain as a ‘petty sovereign’, operating under the state of exception established by the US Executive. UK authorities have not themselves suspended the rule of law so overtly, and indeed have repeatedly insisted on their commitment to it. They have nevertheless been able to construct a rhetorical, legal and policy ‘scaffold’ that has enabled them to demonstrate at least procedural adherence to human rights norms, while at the same time allowing UK officials to acquiesce in the arbitrary exercise of sovereignty over individuals who are denied any access to appropriate representation or redress in compliance with the rule of law
The limits to libertarian paternalism: two new critiques, and seven best practice imperatives
publication-status: AcceptedCopyright © 2012 PionGill N, Gill M, 2012. The definitive, peer-reviewed and edited version of this article is published in Environment and Planning C, 2012, Vol. 30, Issue 5, pp. 924 - 940Behavioural economists argue that humans are predictably irrational in various ways, as a result of which there appears to be a role for public policy to improve their decision-making. We offer a sympathetic critique of this so-called ‘libertarian paternalist’ approach. As well as reviewing existing critiques, we present two new arguments. First, we question the use of libertarian paternalism in situations where the social good is invoked to justify policies that are not beneficial to the individuals directly affected. Second, we highlight the potentially adverse consequences of poorly targeted libertarian paternalist techniques. The penultimate section then brings together the existing critiques and the new arguments to offer seven best practice imperatives for the reflective application of these powerful, but easily misused, tools of government. We conclude with some brief reflections on what freedom might mean in the context of libertarian paternalist governance
Crimean-Congo hemorrhagic fever: epidemiological trends and controversies in treatment
Crimean-Congo hemorrhagic fever (CCHF) virus has the widest geographic range of all tick-borne viruses and is endemic in more than 30 countries in Eurasia and Africa. Over the past decade, new foci have emerged or re-emerged in the Balkans and neighboring areas. Here we discuss the factors influencing CCHF incidence and focus on the main issue of the use of ribavirin for treating this infection. Given the dynamics of CCHF emergence in the past decade, development of new anti-viral drugs and a vaccine is urgently needed to treat and prevent this acute, life-threatening disease
Pan-Cancer Proteogenomics Characterization of Tumor Immunity
Despite the successes of immunotherapy in cancer treatment over recent decades, less than \u3c10%-20% cancer cases have demonstrated durable responses from immune checkpoint blockade. To enhance the efficacy of immunotherapies, combination therapies suppressing multiple immune evasion mechanisms are increasingly contemplated. To better understand immune cell surveillance and diverse immune evasion responses in tumor tissues, we comprehensively characterized the immune landscape of more than 1,000 tumors across ten different cancers using CPTAC pan-cancer proteogenomic data. We identified seven distinct immune subtypes based on integrative learning of cell type compositions and pathway activities. We then thoroughly categorized unique genomic, epigenetic, transcriptomic, and proteomic changes associated with each subtype. Further leveraging the deep phosphoproteomic data, we studied kinase activities in different immune subtypes, which revealed potential subtype-specific therapeutic targets. Insights from this work will facilitate the development of future immunotherapy strategies and enhance precision targeting with existing agents
Synthesis report of the IPCC Sixth Assessment Report (AR6), Longer report. IPCC.
This Synthesis Report (SYR) of the IPCC Sixth Assessment Report (AR6) summarises the state of knowledge of climate change, its widespread impacts and risks, and climate change mitigation and adaptation, based on the peer-reviewed scientific, technical and socio-economic literature since the publication of the IPCC’s Fifth Assessment Report (AR5) in 2014.
The assessment is undertaken within the context of the evolving international landscape, in particular, developments in the UN Framework Convention on Climate Change (UNFCCC) process, including the outcomes of the Kyoto Protocol and the adoption of the Paris Agreement. It reflects the increasing diversity of those involved in climate action.
This report integrates the main findings of the AR6 Working Group reports1
and the three AR6 Special Reports. It recognizes the interdependence of climate, ecosystems and biodiversity, and human societies; the value of diverse forms of knowledge; and the close linkages between climate change adaptation, mitigation, ecosystem health, human well-being and sustainable development. Building on multiple analytical frameworks, including those from the physical and social sciences, this report identifies opportunities for transformative action which are effective, feasible, just and equitable using concepts of systems transitions and resilient development pathways. Different regional classification schemes are used for physical, social and economic aspects, reflecting the underlying literature.
After this introduction, Section 2, ‘Current Status and Trends’, opens with the assessment of observational evidence for our changing climate, historical and current drivers of human-induced climate change, and its impacts. It assesses the current implementation of adaptation and mitigation response options. Section 3, ‘Long-Term Climate and Development Futures’, provides a long-term assessment of climate change to 2100 and beyond in a broad range of socio-economic futures. It considers long-term characteristics, impacts, risks and costs in adaptation and mitigation pathways in the context of sustainable development. Section 4, ‘Near-Term Responses in a Changing Climate’, assesses opportunities for scaling up effective action in the period up to 2040, in the context of climate pledges, and commitments, and the pursuit of sustainable development.
Based on scientific understanding, key findings can be formulated as statements of fact or associated with an assessed level of confidence using the IPCC calibrated language5
. The scientific findings are drawn from the underlying reports and arise from their Summary for Policymakers (hereafter SPM), Technical Summary (hereafter TS), and underlying chapters and are indicated by {} brackets.

Contextualising Apartheid at the End of Empire: Repression, ‘Development’ and the Bantustans
This article examines the global dynamics of late colonialism and how these informed
South African apartheid. More specifically, it locates the programmes of mass
relocation and bantustan ‘self-government’ that characterised apartheid after 1959 in
relation to three key dimensions. Firstly, the article explores the global circulation of
idioms of ‘development’ and trusteeship in the first half of the twentieth century and its
significance in shaping segregationist policy; secondly, it situates bantustan ‘selfgovernment’
in relation to the history of decolonisation and the partitions and
federations that emerged as late colonial solutions; and, thirdly, it locates the
tightening of rural village planning in the bantustans after 1960 in relation to the
elaboration of anti-colonial liberation struggles, repressive southern African settler
politics and the Cold War. It argues that, far from developing policies that were at odds
with the global ‘wind of change’, South African apartheid during the 1960s and 1970s
reflected much that was characteristic about late colonial strategy
