From Stigma to Strength? The Interrelations Between Sexual Identity Stigma, Well-Being, and Accepting Communities on Instagram Amongst Sexual Minority Youth.

Introduction: Initial evidence suggests that engaging with accepting communities on social media such as Instagram may inform sexual minority youths' sense of stigma and well-being. However, as existing research has predominately drawn upon cross-sectional or qualitative designs, it is currently unclear whether the positive experiences identified in previous research accumulate, endure, or evolve over time. We also know relatively little about whether engagement with accepting online communities is primarily a compensatory or enhancing behavior.

Positive Body Image in Adolescence: Longitudinal Associations With Identity and Eating Disorder Symptoms.

Developmental research has mostly focused on negative body image, somewhat neglecting the role positive body image plays in adolescent development. To fill this gap, the present longitudinal study investigated the directionality of effects among positive body image, identity, and eating disorder symptoms across one year. Two waves of data were collected from a sample of 915 high school students in Flanders (T1: 60% female; M = 16.

Heat capacity of periodically driven two-level systems.

We define the heat capacity for steady periodically driven systems and as an example we compute it for dissipative two-level systems where the energy gap is time-modulated. There, as a function of ambient temperature, the Schottky peak remains the dominant feature. Yet, in contrast with equilibrium, the quasistatic thermal response of a nonequilibrium system also reveals kinetic information present in the transition rates; e.

Safety and Immunogenicity of a 4-Component Generalized Modules for Membrane Antigens Shigella Vaccine in Healthy European Adults: Randomized, Phase 1/2 Study.

Background: We report data from stage 1 of an ongoing 2-staged, phase 1/2 randomized clinical trial with a 4-component generalized modules for membrane antigens-based vaccine against Shigella sonnei and Shigella flexneri 1b, 2a, and 3a (altSonflex1-2-3; GSK).

Methods: Europeans aged 18-50 years (N = 102) were randomized (2:1) to receive 2 injections of altSonflex1-2-3 or placebo at 3- or 6-month interval. Safety and immunogenicity were assessed at prespecified time points.
