The influence of workload on muscle fatigue, tissue properties, and postural stability in older and younger workers.

Demographic aging and extended working lives have prompted interest in the physiological changes that occur with age, particularly in the lumbar spine. Age-related declines in muscle quality and intervertebral disc alterations may reduce muscular endurance, strength, and postural stability, potentially increasing the risk of musculoskeletal injuries in older workers. As experienced workers play an important role in addressing labor shortages, understanding the impact of age-related physiological changes on the biomechanical properties of the lumbar spine is key to ensure safe and sustainable employment for aging individuals.

Heavy users, mobile gamers, and social networkers: Patterns of objective smartphone use in parents of infants and associations with parent depression, sleep, parenting, and problematic phone use.

Smartphone use during parenting is common, which may lead to distraction (also known as technoference). However, it is likely that some phone activities are less disruptive to parents and children. In this study, we explored smartphone use (via passive sensing across 8 days) within 264 parents of infants, measuring parents' application use on their phone (e.

Recent research involving consent, alcohol intoxication, and memory: Implications for expert testimony in sexual assault cases.

When adjudicating sexual assault cases, it is imperative that attorneys are educated on the incident characteristics relevant to their case and that expert witnesses are prepared to consult and/or testify regarding relevant science. Most reported sexual assault cases occur when at least one of the relevant parties has consumed alcohol, which has neurochemical, behavioral, psychological, and cognitive effects that are important to consider relative to the facts of the case. Nearly a decade ago, Connell (2015) provided an overview of research relevant to an expert witness's role in these types of cases.

Multi-Frequency Nonlinear Methods for 3D Shape Measurement of Semi-Transparent Surfaces Using Projector-Camera Systems.

Measuring the 3D shape of semi-transparent surfaces with projector-camera 3D scanners is a difficult task because these surfaces weakly reflect light in a diffuse manner, and transmit a large part of the incident light. The task is even harder in the presence of participating background surfaces. The two methods proposed in this paper use sinusoidal patterns, each with a frequency chosen in the frequency range allowed by the projection optics of the projector-camera system.

Daily smartphone use predicts parent depressive symptoms, but parents' perceptions of responsiveness to their child moderate this effect.

Introduction: Smartphone use during caregiving has become increasingly common, especially around infants and very young children, and this use around young children has been linked with lower quality and quantity of parent-child interaction, with potential implications for child behavior, and parent-child attachment. To understand drivers and consequences of parent phone use, we were interested in the daily associations between parent phone use and depressed mood, as well as the potential for parent perceptions of their responsiveness toward their infant to alter the association between parent phone use and mood.

Methods: In the present study, we explored associations between day-to-day changes in parent smartphone use (objectively-measured via passive sensing) around their infant, depressed mood, and parent perceptions of their responsiveness to their infants among a sample of 264 parents across eight days.
