Objectives
Evaluate the relationship between cardiovascular disease (CVD) risk factors and cochlear function in African Americans.
Methods
Relationships between hearing loss, cochlear function, and CVD risk factors were assessed in a cross-sectional analysis of 1106 Jackson Heart Study participants. Hearing loss was defined as puretone average (PTA0.5,1,2,4) > 15 dB HL. Distortion...
Microbial communities in alpine environments >7,500 m.a.s.l. have not been well studied using modern cultivation-independent sequencing approaches due to the challenges and danger associated with reaching such high elevations. For this reason, we know little about the microorganisms found in sediments on Earth’s tallest mountains, how they reach these surfaces,...
Background
The 1.5 generation, brought to the U.S. prior to age 16, faces barriers that the second generation, U.S.-born to immigrant parents, does not, including only temporary legal protection through the Deferred Action for Childhood Arrivals (DACA) Program. Little is known about how legal status and uncertainty shape cisgender...
Students sometimes learn about a model of the “scientific method” that is linear and clear cut. While this approach may have pedagogical advantages, it does not reflect how science is often done in practice. The Experimental Modeling Framework (EMF) describes the complex and iterative process of experimentation in the domain...
Fluid-preserved reptile and amphibian specimens are challenging to photograph with traditional methods due to their complex three-dimensional forms and reflective surfaces when removed from solution. An effective approach to counteract these issues involves combining focus stack photography with the use of a photo immersion tank. Imaging specimens beneath a...
Prior research suggests that Indigenous fire management buffers climate influences on wildfires, but it is unclear whether these benefits accrue across geographic scales. We use a network of 4824 fire-scarred trees in Southwest United States dry forests to analyze up to 400 years of fire-climate relationships at local, landscape, and...
The COVID-19 pandemic resulted in government restrictions that altered the lifestyle of people worldwide. Studying the impact of these restrictions on exercise behaviors will improve our understanding of the environmental factors that influence individuals’ physical activity (PA). We conducted a retrospective analysis using an stringency index of government pandemic policies...
Seasonal transitions in Arctic sea ice, such as the melt onset, have been found to be useful metrics for evaluating sea ice in climate models against observations. However, comparisons of melt onset dates between climate models and satellite observations are indirect. Satellite data products of melt onset rely on observed...
The combustion of solid fuels in residential cookstoves is a global health and climate issue, and expanded use ofimproved cookstoves could have significant benefits locally and globally. Evaluating impacts of improved cookstove programs requires more accurately measuring stove use patterns. This work builds on and improves existing stove use monitoring...
This study investigates the impact of a theatre-based vocal empowerment program on the vocal and language characteristics and the self-perceptions of young bilingual Egyptian women. The program used applied theatre, a dramatic practice that promotes civic action by utilizing improvisational techniques to engage participants in exploring solutions to self-identified community...
