Look at that-the positive effect of video observation on physical stair climbing performance.

Psychol Aging 2018 Dec;33(8):1195-1201

Institute of Training and Computer Science in Sport.

To examine the effect of short-term video presentation intervention (VPI) on stair self-efficacy and on stair-climbing ability, 90 participants age 65 and above were randomly assigned to 3 groups: The first intervention group watched role models descending the same staircase used for testing, the second intervention group watched role models descending an unfamiliar staircase, and the control group watched an irrelevant control video. This study found that stair-climbing duration was shortened compared with the pretest without affecting movement fluency as supported by the social-cognitive theory. We interpret this outcome as evidence for improved self-efficacy: the intervention strengthened our participants' belief that they can successfully complete the task. Read More

A self-regulation perspective on how and when regulatory focus differentially relates to citizenship behaviors.

J Appl Psychol 2018 Dec 13. Epub 2018 Dec 13.

School of Business Administration.

Although previous research suggests that regulatory focus matters for organizational citizenship behaviors, it is unclear how promotion and prevention focus relate to such behaviors. Integrating regulatory focus theory with theories of self-regulation, we propose a conceptual model that links trait promotion and prevention foci with specific citizenship behaviors through an emotion-related self-regulation mechanism. Using a sample of 227 nurses working in a hospital context, we observed that trait promotion focus and trait prevention focus predict helping and voice via differential effects on emotional exhaustion.

Bioinspired Engineering of Multivalent Aptamer-Functionalized Nanointerface to Enhance Capture and Release of Circulating Tumor Cells.

Angew Chem Int Ed Engl 2018 Dec 13. Epub 2018 Dec 13.

College of Chemistry and Chemical Engineering Xiamen University, State Key Lab of Physical Chemistry of Solid Surfaces, 482 Siming South,, Siming Qu, 361005, Xiamen, CHINA.

Circulating tumor cells (CTCs) enrichment by aptamers shows a number of advantages, but the issue of compromised binding affinities and stabilities in real samples hinders their wide applications. Inspired by the high efficiency of the prey mechanism of octopus, we engineered a deterministic lateral displacement (DLD) patterned microfluidic chip modified with interfaces mimicking the multivalent tentacles of octopus using aptamer-functionalized nanospheres, called as aptamer-tailed octopus-chip (AP-Octopus-Chip) to enhance capture efficiency. The multivalent aptamer-antigen binding improves 100 folds and the capture efficiency enhanced more than 300% compared with a monovalent aptamer modified chip. Read More
