WATER REPELLENT RENDERINGS FOR THE DAMP-PROOFING OF MONUMENTS

The global transitional justice tool kit—involving the use of criminal prosecutions, amnesties, and other mechanisms to address past human rights abuse—has become a primary means for thwarting future human rights violations and consolidating democracy. Nevertheless, evidence on the consequences of transitional justice remains mixed and amenable to contradictory interpretations. Existing studies fail to adequately address issues of selection, the difference between short- and long-term effects of transitional justice mechanisms, and qualitative and quantitative differences in state practices. This article uses a new database of transitional justice mechanisms to address these concerns and test propositions from realist, constructivist, and holistic approaches to this set of policy issues. We find, among other things, that prosecutions increase physical integrity protections, while amnesties increase the protection of civil and political rights. Our analysis suggests that different transnational justice policies each play a potentially positive, but distinct, role in new democracies and in decreasing violations of human rights

A Fire Severity Mapping System for Real-Time Fire Management Applications and Long-Term Planning: The FIRESEV project

Accurate, consistent, and timely fire severity maps are needed in all phases of fire management including planning, managing, and rehabilitating wildfires. The problem is that fire severity maps are commonly developed from satellite imagery that is difficult to use for planning wildfire responses before a fire has actually happened and can’t be used for real-time wildfire management because of the timing of the imagery delivery. Moreover, imagery is difficult to use for controlled fires such as prescribed burning. This study, called FIRESEV (FIRE SEVerity Mapping Tools) created a comprehensive set of tools and protocols to deliver, create, and evaluate fire severity maps for all phases of fire management. The first tool is a Severe Fire Potential Map (SFPM) that quantifies the potential for fires to burn with high severity, should they occur, for any 30m x 30m piece of ground across the western United States. This map was developed using empirical models that related topographic, vegetation, and fire weather variables to burn severity as mapped using the Monitoring Trends in Burn Severity (MTBS) digital products. This SFPM map is currently available on the Fire Research and Management Exchange System (FRAMES, http://www.frames.gov/firesev) web site and can be used to plan for future wildfires or for managing wildfires in real time, e.g. by including it as a layer in Wildland Fire Decision Support System or other GIS analysis. The next tool was the inclusion of a fire severity mapping algorithm in the Wildland Fire Assessment Tool (WFAT) developed by the National Interagency Fuels Technology Transfer (NIFTT) team. WFAT is used for fuel treatment planning to predict potential fire effects under prescribed fire weather conditions (http://www.frames.gov/partner-sites/niftt/tools/niftt-current-resources/). Now, fire severity can be mapped explicitly from fire effects simulation models (FOFEM, Consume) for real-time and planning wildfire applications. Next, the FIRESEV project showed how results from the WFAT simulated fire severity can be integrated with satellite imagery to improve fire severity mapping. And last, the FIRESEV project produced a suite of research studies, synthesis papers, and popular articles designed to improve the description, interpretation, and mapping of fire severity for wildland fire management: (1) a research study created a completely objective method of quantifying fire severity from fire effects to obtain nine unique classes of fire severity, (2) a research study comprehensively contrasted all current classifications of fire severity using Composite Burn Index (CBI) as measured on over 300 plots across the western United States to determine commonalities and differences, and (3) a synthesis paper was written discussing the problems involved in measuring, describing, and quantifying fire severity. This FIRESEV project yielded over 15 deliverables that we feel provides a comprehensive suite of products to create useful fire severity maps, along with current satellite imagery products, and also FIRESEV provides a thorough background on how to measure, interpret, and apply fire severity in fire management

E-Cadherin mediates UVR- and calcium-induced melanin transfer in human skin cells

yesSkin pigmentation is directed by epidermal-melanin units, characterized by long-lived and dendritic epidermal melanocytes (MC) that interact with viable keratinocytes (KC) to contribute melanin to the epidermis. Previously we reported that MC:KC contact is required for melanosome transfer, that this can be enhanced by filopodial and by UVR/UVA irradiation, which can up-regulate melanosome transfer via Myosin X-mediated control of MC filopodia. Both MC and KC express Ca2+-dependent E-cadherins. These homophilic adhesion contacts induce transient increases in intra-KC Ca2+, while ultraviolet radiation (UVR) raises intra-MC Ca2+ via calcium selective ORAI1 ion channels; both are associated with regulating melanogenesis. However, how Ca2+ triggers melanin transfer remains unclear, and here we evaluated the role of E-Cadherin in UVR-mediated melanin transfer in human skin cells. MC and KC in human epidermis variably express filopodia-associated E-Cadherin, Cdc42, VASP and β-catenin, all of which were upregulated by UVR/UVA in human MC in vitro. Knockdown of E-cadherin revealed that this cadherin is essential for UVR-induced MC filopodia formation and melanin transfer. Moreover, Ca2+ induced a dose-dependent increase in filopodia formation and melanin transfer, as well as increased β-catenin, Cdc42, Myosin X, and E-Cadherin expression in these skin cells. Together these data suggest that filopodial proteins and E-Cadherin, which are upregulated by intracellular (UVR-stimulated) and extracellular Ca2+ availability, are required for filopodia formation and melanin transfer. This may open new avenues to explore how Ca2+ signalling influences human pigmentation

Conflict and Astroturfing in Niyamgiri: The Importance of National Advocacy Networks in Anti-Corporate Social Movements

Traditional models of transnational advocacy networks (TANs) and stakeholder management do not capture the nuance and dynamics of (counter-)organising processes around anti-corporate mobilisation. Based on the case of a resistance movement against a planned bauxite mine on tribal land in India, we develop a process theory of interactions between local, national and international actors within transnational advocacy networks. These encounters are not always friendly and are often characterised by conflict between actors with disparate goals and interests. We highlight the importance of national advocacy networks (NANs) in anti-corporate social movements and describe the conflicts and disruptions that result from ignoring them. Our findings also point to the role of corporate counter-mobilisation strategies in shaping resistance movements. Our narrative revolves around a particular focal actor in the anti-mining campaign: a young tribal man who emerged as a passionate spokesperson of the movement, but later became a supporter of the controversial mine. Our findings contribute to a richer understanding of the processes underlying transnational and national anti-corporate mobilisation

Truth Commissions after Economic Crises: Political Learning or Blame Game?

This article addresses an important but understudied aspect of the recent Great Recession in Europe: the institutional strategies political elites deployed to learn from past policy failures and address accountability, more specifically, truth commissions. We raise two overlapping puzzles. The first concerns the timing of the decision to adopt an economic truth commission: while Iceland established a truth commission at an early stage of the crisis, Greece and Ireland did so much later. What accounts for ‘early’ versus ‘delayed’ truth seekers? The second concerns variations in learning outcomes. Iceland’s commission paved the way for learning institutional lessons, but truth commissions in Greece and Ireland became overtly politicised. What accounts for these divergences? This article compares truth commissions in Iceland, Greece and Ireland and identifies two types of political learning – institutional and instrumental – related to the establishment of a truth commission. It argues that political elites in countries with higher pre-crisis levels of trust in institutions and public transparency are more likely to establish economic truth commissions quickly; this is the ‘institutional logic’ of learning. The ‘instrumental logic’ of learning, in contrast, leads governments interested in apportioning blame to their predecessors to establish commissions at a later date, usually proximal to critical elections

Lament as Transitional Justice

Works of human rights literature help to ground the formal rights system in an informal rights ethos. Writers have developed four major modes of human rights literature: protest, testimony, lament, and laughter. Through interpretations of poetry in Carolyn Forché’s anthology, Against Forgetting, and novels from Rwanda, the United States, and Bosnia, I focus on the mode of lament, the literature of mourning. Lament is a social and ritualized form, the purposes of which are congruent with the aims of transitional justice institutions. Both laments and truth commissions employ grieving narratives to help survivors of human rights trauma bequeath to the ghosts of the past the justice of a monument while renewing the survivors’ capacity for rebuilding civil society in the future. Human rights scholars need a broader, extra-juridical meaning for “transitional justice” if we hope to capture its power

In Vitro Aggregation Behavior of a Non-Amyloidogenic λ Light Chain Dimer Deriving from U266 Multiple Myeloma Cells

Excessive production of monoclonal light chains due to multiple myeloma can induce aggregation-related disorders, such as light chain amyloidosis (AL) and light chain deposition diseases (LCDD). In this work, we produce a non-amyloidogenic IgE λ light chain dimer from human mammalian cells U266, which originated from a patient suffering from multiple myeloma, and we investigate the effect of several physicochemical parameters on the in vitro stability of this protein. The dimer is stable in physiological conditions and aggregation is observed only when strong denaturating conditions are applied (acidic pH with salt at large concentration or heating at melting temperature Tm at pH 7.4). The produced aggregates are spherical, amorphous oligomers. Despite the larger β-sheet content of such oligomers with respect to the native state, they do not bind Congo Red or ThT. The impossibility to obtain fibrils from the light chain dimer suggests that the occurrence of amyloidosis in patients requires the presence of the light chain fragment in the monomer form, while dimer can form only amorphous oligomers or amorphous deposits. No aggregation is observed after denaturant addition at pH 7.4 or at pH 2.0 with low salt concentration, indicating that not a generic unfolding but specific conformational changes are necessary to trigger aggregation. A specific anion effect in increasing the aggregation rate at pH 2.0 is observed according to the following order: SO4−≫Cl−>H2PO4−, confirming the peculiar role of sulfate in promoting protein aggregation. It is found that, at least for the investigated case, the mechanism of the sulfate effect is related to protein secondary structure changes induced by anion binding

Human Rights and the Pink Tide in Latin America : Which Rights Matter?

Latin America witnessed the election of ‘new Left’ governments in the early 21 st century that, in different ways, sought to open a debate about alternatives to paradigms of neoliberal development. What has this meant for the way that human rights are understood and for patterns of human rights compliance? Using qualitative and quantitative evidence, this article discusses how human rights are imagined and the compliance records of new Left governments through the lens of the three ‘generations’ of human rights — political and civil, social and economic, and cultural and environmental rights. The authors draw in particular on evidence from Andean countries and the Southern Cone. While basic civil and individual liberties are still far from guaranteed, especially in the Andean region, new Left countries show better overall performances in relation to socio-economic rights compared to the past and to other Latin American countries. All new Left governments also demonstrate an increasing interest in ‘third generation’ (cultural and environmental) rights, though this is especially marked in the Andean Left. The authors discuss the tensions around interpretations and categories of human rights, reflect on the stagnation of first generation rights and note the difficulties associated with translating second and third generation rights into policy
