University student perceptions of health and disease during remote learning in the COVID-19 pandemic.

Objectives: Assess student perceptions of health and disease during remote learning in the COVID-19 pandemic.

Participants: Convenience sample of undergraduate students at a liberal arts university (n = 67).

Methods: Survey administered across multiple sections of a required general education course in Spring 2020.

Spermathecal Filling in Aedes aegypti and Aedes albopictus: Effects of Female and Male Body Sizes and Species.

The mosquitoes Aedes aegypti (L.) (Diptera: Culicidae) and Aedes albopictus (Skuse) (Diptera: Culicidae) are ecologically similar species that have evolved independently in their native ranges, Ae. aegypti in Africa and Ae.

Decisions in changing conditions: the urgency-gating model.

Several widely accepted models of decision making suggest that, during simple decision tasks, neural activity builds up until a threshold is reached and a decision is made. These models explain error rates and reaction time distributions in a variety of tasks and are supported by neurophysiological studies showing that neural activity in several cortical and subcortical regions gradually builds up at a rate related to task difficulty and reaches a relatively constant level of discharge at a time that predicts movement initiation. The mechanism responsible for this buildup is believed to be related to the temporal integration of sequential samples of sensory information.

Intensity of therapy services: what are the considerations?

Research on intensity of therapy services is limited and perspectives often vary considerably among families, therapists, administrators, policy makers, and health insurers. In this commentary, the authors share their perspectives on intensity of physical therapy and/or occupational therapy services for children with developmental conditions. Five considerations are discussed: episode of therapy, readiness for activity and participation, method of service delivery, the distinction between intensity of therapy and practice of activity in natural environments, and the link between skill level and method of service delivery.
