Effects of UV Stabilizers on Polypropylene Outdoors
This article looks at hindered amine light stabilizers (HALSs) and nano ZnO were used to stabilize polypropylene (PP) film-based formulations that were exposed to ultraviolet (UV) light for different lengths of time, simulating the harsh outdoor weather of Dallas, Texas, USA. UV doses applied in our laboratory are 121 times larger than the UV dose provided by the sunlight in Texas. 15 different compositions were studied. The combination of HALSs and nano-ZnO stabilizers makes the PP films harder—which is important for some PP applications, such as toy manufacturing.

Ending the Evidentiary & Insurance Reimbursement Bias Against Neurofeedback to Treat Attention Deficit/Hyperactivity Disorder: It Will Take Clinician Action in Addition to the Compelling Science
This article argues against the treatment of Attention deficit/hyperactivity disorder (ADHD) with stimulant medication and behavior therapy, which are also typically reimbursed by healthcare insurers. Evidence suggests that these treatments fail to result in sustained benefit for the vast majority of children who receive them as demonstrated in the NIMH-funded MTA Cooperative study, the gold standard study in ADHD treatment effectiveness research. The authors instead look at the use of neurofeedback which is uniquely suited to treat the neuronal dysregulation that is common in people diagnosed with ADHD. However, healthcare insurers do not regularly cover this treatment method, so the authors direct readers to resources to appeal insurers' denial of coverage for neurofeedback.

Mechanisms of Social Interaction and Virtual Connections as Strong Predictors of Wellbeing of Older Adults
Article examining the domains of social determinants of health, specifically the social and community context per Healthy People 2030 objectives. These mechanisms of social interaction, in the form of group activities, community engagement, and virtual interactions via email or text message, were assessed using hierarchical regression analysis to find out their association with wellbeing, depression symptoms, and cognition of older adults.

Perception of Falls and Confidence in Self-Management of Falls among Older Adults
This article investigates the relative contribution of confidence of self-management in falls (CSMoF) in relation to fall risk self-perceptions while controlling for demographics and self-reported health and functioning. The joint effects of perception of falls and fear of falls likely explain CSMoF among older adults more than physical functional indicators. Fall prevention programs for older adults should prioritize to address modifiable subjective factors of fall perceptions, fear of falls, and CSMoF across health and functioning statuses.

Assessment of Safe Listening Intentional Behavior Toward Personal Listening Devices in Young Adults
This article explores the use of Theory of Planned Behavior (TPB) to identify attitudes, social norms, and behavioral control in 92 young adults toward two intentional behaviors related to safe listening habits while listening to their personal listening devices: (1) lowering the intensity of loud music, and (2) shortening the listening duration of loud music. Linear regression findings indicated that the overall TPB models were significant. Positive attitudes toward turning the music down and shortening the durations were significantly associated with intentions to engage in non-risky behavior, more so for the former behavior.
