Uncertainty budget for detector-based absolute radiometric calibration with GLAMR.

The accuracy of the absolute radiometric calibration (RadCal) for remote sensing instruments is essential to their wide range of applications. The uncertainty associated with the traditional source-based RadCal method is assessed at a 2% (=1) or higher level for radiance measurement. To further improve the accuracy to meet the demands of climate studies, a detector-based approach using tunable lasers as a light source has been devised.

An Equity-Based Scoring System for Evaluating Surveillance-Related Harm in Public Health Crises.

Background: Although surveillance systems used to mitigate disasters serve essential public health functions, communities of color have experienced disproportionate harms (eg, criminalization) as a result of historic and enhanced surveillance.

Methods: To address this, we developed and piloted a novel, equity-based scoring system to evaluate surveillance systems regarding their potential and actual risk of adverse effects on communities made vulnerable through increased exposure to policing, detention/incarceration, deportation, and disruption of access to social services or public resources. To develop the scoring system, we reviewed the literature and surveyed an expert panel on surveillance to identify specific harms (eg, increased policing) that occur through surveillance approaches.

An exploratory study to characterize the HIV testing-to-care continuum to improve outcomes for Black and Latinx residents of South Los Angeles.

Background: South Los Angeles (SPA6), with mostly Black (27.4%) and Latinx (68.2%) residents, has the second highest rates of new HIV diagnoses (31 per 100,000) in Los Angeles County.

Integrated Methods for Applying Critical Race Theory to Qualitative COVID-19 Equity Research.

Background: Racism persists, underscoring the need to rapidly document the perspectives and experiences of Black, Indigenous and People of Color (BIPOC) groups as well as marginalized populations (eg, formerly incarcerated people) during pandemics.

Objective: This methods paper offers a model for using Public Health Critical Race Praxis (PHCRP) and related critical methodologies (ie, feminist and decolonizing methods) to inform the conceptualization, methods, and dissemination of qualitative research undertaken in response to the evolving COVID-19 pandemic.

Sample: Using purposive snowball sampling, we identified organizations involved with health equity and social justice advocacy among BIPOC and socially marginalized populations.

Sex determination in the GIFT strain of tilapia is controlled by a locus in linkage group 23.

Background: Tilapias (Family Cichlidae) are the second most important group of aquaculture species in the world. They have been the subject of much research on sex determination due to problems caused by early maturation in culture and their complex sex-determining systems. Different sex-determining loci (linkage group 1, 20 and 23) have been detected in various tilapia stocks.
