Environmental justice and conceptions of the green economy

Green economy has become one of the most fashionable terms in global environmental public policy discussions and forums. Despite this popularity, and its being selected as one of the organizing themes of the United Nations Rio+20 Conference in Brazil, June 2012, its prospects as an effective mobilization tool for global environmental sustainability scholarship and practice remains unclear. A major reason for this is that much like its precursor concepts such as environmental sustainability and sustainable development, green economy is a woolly concept which lends itself to many interpretations. Hence, rather than resolve long-standing controversies, green economy merely reinvigorates existing debates over the visions, actors and policies best suited to secure a more sustainable future for all. In this review article, we aim to fill an important gap in scholarship by suggesting various ways in which green economy may be organized and synthesized as a concept, and especially in terms of its relationship with the idea of social and environmental justice. Accordingly, we offer a systemization of possible interpretations of green economy mapped onto a synthesis of existing typologies of environmental justice. This classification provides the context for future analysis of which, and how, various notions of green economy link with various conceptions of justice

When words become borders:Ingroup favoritism in perceptions and mental representations of Anglo-Canadian and Franco-Canadian faces

Language is critical to social identity, including nationality. However, some nations encompass multiple languages, raising questions about how their citizens perceive members of their national versus linguistic groups. We explored perceptions of Canadian nationality, which consists of two linguistic groups: Anglo-Canadians and Franco-Canadians. In Study 1, we used reverse correlation methods to visualize how Anglo- and Franco-Canadians mentally represent the faces of linguistic ingroup and outgroup members, and of Canadians in general. Structural similarity analyses and subjective ratings of the resulting images showed that both groups mentally represented Canadians as more similar to their own linguistic ingroup. In Study 2, Anglo-Canadians and Franco-Canadians rated photos of real Anglo- and Franco-Canadian targets. Both samples showed some ingroup favoritism when inferring their traits but only Anglo-Canadians could accurately differentiate group members. Differences between Anglo-Canadians and Franco-Canadians therefore extend beyond language, with linguistic groups impacting impressions before any words are spoken

Perceptions of COVID-19 Vaccines: Lessons from Selected Populations Who Experience Discrimination in the Australian Healthcare System

COVID-19 vaccination is particularly challenging among populations who have experienced discrimination in healthcare settings. This paper presents qualitative findings from in-depth interviews about COVID-19 vaccination conducted in Australia between October 2020 and November 2021. Data from four different studies are presented; each population has unique experiences of discrimination within the healthcare system: Aboriginal people; people who inject drugs (PWID); people living with HIV (PLHIV); and gay and bisexual men (GBM). Analyses were guided by the behavioural and social determinants model that forms the basis of the World Health Organization’s “data for action: achieving high uptake of COVID-19 vaccines” interim guidance. All populations viewed vaccination as necessary for community protection, although narratives of community care were most common among Aboriginal people. Concerns about vaccine safety were expressed by all participant groups, although participants living with HIV and GBM were more trusting of vaccines possibly because of their ongoing and usually positive past experiences with biomedical technologies for HIV management and sexual health. Aboriginal participants reported distrust of mainstream government and participants who inject drugs expressed a more generalised suspicion about COVID-19 and its origins. Practical problems related to transport, booking appointments for vaccination and so forth, were more common among participants living with HIV and GBM, possibly because these specific interviews were conducted throughout 2021 when vaccines were more available, whereas data for the other populations were collected before the vaccine rollout. Findings show that vaccine willingness is shaped by past experiences of discrimination in healthcare setting, but different histories of discrimination can differently impact vaccine willingness. Promotional messaging and delivery must take account of these important differences so to not treat these populations homogenously

Phase 1b study of tirabrutinib in combination with idelalisib or entospletinib in previously treated B-cell lymphoma.

B-cell receptor (BCR) signaling pathway inhibitors (including Bruton’s tyrosine kinase [BTK] inhibitors, and phosphatidylinositol-3 kinase inhibitors [PI3Ki]) have shown clinical efficacy in non-Hodgkin lymphoma (NHL). However, responses to these agents have been limited in depth and duration. This may be due to resistance to PI3Kδ and BTK inhibitors as monotherapy. The emergence of resistant clones may be addressed by combining these 2 classes of drugs. Furthermore, tolerability of these drug classes has been a concern. Combination therapy using lower doses of one or more classes of inhibitor may address some limitations

Dynamic Nanodomains Dictate Macroscopic Properties in Lead Halide Perovskites

Empirical A-site cation substitution has advanced the stability and efficiency of hybrid organic-inorganic lead halide perovskites solar cells and the functionality of X-ray detectors. Yet, the fundamental mechanisms underpinning their unique performance remain elusive. This multi-modal study unveils the link between nanoscale structural dynamics and macroscopic optoelectronic properties in these materials by utilising X-ray diffuse scattering, inelastic neutron spectroscopy and optical microscopy complemented by state-of-the-art machine learning-assisted molecular dynamics simulations. Our approach uncovers the presence of dynamic, lower-symmetry local nanodomains embedded within the higher-symmetry average phase in various perovskite compositions. The properties of these nanodomains are tunable via the A-site cation selection: methylammonium induces a high density of anisotropic, planar nanodomains of out-of-phase octahedral tilts, while formamidinium favours sparsely distributed isotropic, spherical nanodomains with in-phase tilting, even when crystallography reveals cubic symmetry on average. The observed variations in the properties of dynamic nanodomains are in agreement with our simulations and are directly linked to the differing macroscopic optoelectronic and ferroelastic behaviours of these compositions. By demonstrating the influence of A-site cation on local nanodomains and consequently, on macroscopic properties, we propose leveraging this relationship to engineer the optoelectronic response of these materials, propelling further advancements in perovskite-based photovoltaics, optoelectronics, and X-ray imaging.Comment: Main text and supplementary information.
