Designing a mobile application to promote physical activity in spousal care partners of persons living with dementia and their care-recipient.

Care partners of persons living with dementia and their care-recipient have low levels of physical activity. Mobile applications have demonstrated effectiveness in promoting physical activity among older adults. The purpose of this study was to explore the perceptions of spousal care partners of persons with dementia and their care-recipient on the design and content of a mobile application intended to promote physical activity.

Facial width-to-height ratio predicts fighting success: A direct replication and extension of Zilioli et al. (2014).

Zilioli et al. (2014) were the first to show an association between male facial width-to-height ratio (fWHR) and physical aggression and fighting ability in professional mixed-martial-arts fighters. Here, we re-examined this relationship by replicating (using all original measures) and extending (using 23 new variables related to fighting performance) Zilioli et al.

Feasibility study of an attention training application for older adults.

Background: Technology-based attention training has demonstrated promise in its potential to improve cognitive functioning in older people. Developing mobile applications, with older users specifically in mind, may support future dissemination of these interventions and integration into daily life.

Aims And Objectives: The purpose of this pilot study was to test the feasibility of an Attention Training Application (ATA) for community-dwelling older adults using mobile technology.

The photomediated reaction of alkynes with cycloalkanes.

In the presence of a photomediator such as benzophenone, alkynes with electron-withdrawing groups react with cycloalkanes to give vinyl cycloalkanes. The reaction involves the regiospecific addition of a photochemically generated cycloalkyl radical to the beta-carbon of the alkyne. The stereochemical outcome of the reaction depends on the nature of the photomediator and alkyne used.
