Perspectives about COVID-19 vaccination among the paralysis community in the United States.

Purpose/objective: We sought to explore perspectives among the paralysis community and caregivers or persons with paralysis (PWP) about the COVID-19 vaccination. Research Method/Design: Data were collected via online survey with multiple choice and open-ended questions from adult PWP and family members and/or caregivers (FC) of PWP. Multiple choice questions were analyzed using descriptive statistics and chi-square analyses were conducted to compare the two groups (PWP and FC); open-ended responses were coded using Hamilton's rapid assessment process.

Interpersonal Affordances and Social Dynamics in Collaborative Immersive Virtual Environments: Passing Together Through Apertures.

An essential question in understanding how to develop and build collaborative immersive virtual environments (IVEs) is recognizing how people perform actions together. Many actions in the real world require that people act without prior planning, and these actions are executed quite successfully. In this paper, we study the common action of two people passing through an aperture together in both the real world (Experiment 1) and in a distributed, collaborative IVE (Experiment 2).

Locomotive Recalibration and Prism Adaptation of Children and Teens in Immersive Virtual Environments.

As virtual reality expands in popularity, an increasingly diverse audience is gaining exposure to immersive virtual environments (IVEs). A significant body of research has demonstrated how perception and action work in such environments, but most of this work has been done studying adults. Less is known about how physical and cognitive development affect perception and action in IVEs, particularly as applied to preteen and teenage children.

Young children's flexible use of semantic cues to word meanings: converging evidence of individual and age differences.

A new test of children's flexible use of semantic cues for word learning extended previous results. In Experiment 1, three- to five-year-olds (N = 51) completed two tests of interpreting several novel words for the same stimulus arrays. Within-sentence phrasal cues implied different stimulus referent properties.

Polycyclic aromatic hydrocarbon-degrading Mycobacterium isolates: their association with plant roots.

Five environmental mycobacterium isolates that degrade polycyclic aromatic hydrocarbons (PAHs) were associated with barley root surfaces after growth of the seedlings from inoculated seed. Mycobacterium cells were detected along the total root length for four of these isolates. These PAH-degrading mycobacterium strains had hydrophilic cell surfaces, whereas one strain, MCS, that was hydrophobic had reduced association along the root length with no cells being detected from the root tips.
