Characterizing the Relationship between HIV Peer Support Groups and Internalized Stigma Among People Living with HIV in Nigeria.

HIV-related stigma remains a significant barrier to implementing effective HIV treatment and prevention strategies in Nigeria. Despite the high uptake of peer support groups among people living with HIV (PLHIV) in Nigeria, the potential role of such peer support on the burden of internalized stigma remains understudied. To address this gap, we conducted a secondary analysis of the PLHIV Stigma Index 2.

What will it take to achieve the sexual and reproductive health and rights of women living with HIV?

This article outlines progress in realizing the sexual and reproductive health and rights of women and girls living with HIV over the last 30 years from the perspective of women living with HIV. It argues that the HIV response needs to go beyond the bio-medical aspects of HIV to achieve our sexual and reproductive health and rights, and considers relevant Joint United Nations Programme on HIV/AIDS (UNAIDS), World Health Organization, United States President's Emergency Plan for AIDS Relief (PEPFAR), Global Fund and other guidelines, what engagement there has been with women living with HIV and whether guidelines/strategies have been adopted. It has been written by women living with HIV from around the world and a few key supporters.

The social transmission of overconfidence.

We propose and test the , which predicts that individuals calibrate their self-assessments in response to the confidence others display in their social group. Six studies that deploy a mix of correlational and experimental methods support this hypothesis. Evidence indicates that individuals randomly assigned to collaborate in laboratory dyads converged on levels of overconfidence about their own performance rankings.

Archetypal Soft-Mode-Driven Antipolar Transition in Francisite Cu_{3}Bi(SeO_{3})_{2}O_{2}Cl.

Model materials are precious test cases for elementary theories and provide building blocks for the understanding of more complex cases. Here, we describe the lattice dynamics of the structural phase transition in francisite Cu_{3}Bi(SeO_{3})_{2}O_{2}Cl at 115 K and show that it provides a rare archetype of a transition driven by a soft antipolar phonon mode. In the high-symmetry phase at high temperatures, the soft mode is found at (0,0,0.
