Risks and Safeguards in Social-Behavioural Research With Adults With Developmental Disabilities: A Qualitative Systematic Review.

Background: We identified participant-level risks and safeguards in social-behavioural research with adults with developmental disabilities.

Method: We conducted a qualitative systematic review on risks and safeguards in peer-reviewed research with adults with developmental disabilities. We identified research reporting on risks and safeguards published between 2009 and 2023 by searching eight databases and conducting hand searches of reference lists.

Postglacial Recolonization of the Southern Ocean by Elephant Seals Occurred From Multiple Glacial Refugia.

The Southern Ocean is warming more rapidly than other parts of our planet. How this region's endemic biodiversity will respond to such changes can be illuminated by studying past events through genetic analyses of time-series data sets, including historic and fossil remains. Archaeological and subfossil remains show that the southern elephant seal (Mirounga leonina) was common along the coasts of Australia and New Zealand in the recent past.

Altered Functional Connectivity Dynamics Serving Cognitive Flexibility in Regular Cannabis Users.

Despite its widespread use and popularity, cannabis is known to impact higher order cognitive processes such as attention and executive function. However, far less is known about the impact of chronic cannabis use on cognitive flexibility, a component of executive function, and this is especially true for the underlying functional connectivity dynamics. To address this, we enrolled 25 chronic cannabis users and 30 demographically matched non-users who completed an interview probing current and past substance use, a urinalysis to confirm self-reported substance use and a task-switch cognitive paradigm during magnetoencephalography (MEG).

Perceptions About Housing and Neighborhood Characteristics Among Aging Adult Black Americans in Two Predominantly Black, Low-Income Neighborhoods in Pittsburgh: A Multi-Method Analysis.

The life expectancy gap between Black and White Americans has narrowed, but progress remains slow due to the persistent consequences of lifetime exposure to structural and interpersonal experiences of racism and discrimination in various settings, for example, disadvantaged housing, neighborhood, and economic conditions. It is important to understand challenges and facilitators to healthy aging among Black Americans, i.e.
