Cure for tantrums? Longitudinal associations between parental digital emotion regulation and children's self-regulatory skills.

Introduction: Parents often use digital devices to regulate their children's negative emotions, e.g., to stop tantrums.

Application of a Multispecies Pulse-Exposure Microalgal Bioassay to Assess Duration and Time-of-Day Influences on the Toxicity of Chemicals.

Aquatic organisms may frequently be exposed to short-term discharges of contaminants, including those from pesticide use, stormwater runoff, or industrial effluents entering waterways. Here, a new microalgal multispecies flow cytometry-based bioassay is used to assess knowledge gaps in risk assessments posed by the short-term exposure of organisms to contaminants. The toxicities of atrazine, metolachlor, and copper were assessed using four exposure scenarios, a 72 h exposure (continuous), an 18 h pulse exposure, and two 3 h pulse exposures (light and dark conditions), that assessed chronotoxicity.

The adoption of point of care testing technologies for respiratory tract infections in primary care in Australia: Challenges and facilitators.

Despite technological advances and readily available point of care test (POCT) devices with rapid turn-around results for respiratory tract infection (RTI) management, their adoption in primary care remains low. This paper summarises the challenges and facilitators of POCT implementation for RTIs in primary care settings in high-income countries. The review of 28 studies identified by systematic searches of electronic databases improves our understanding of the current state and will help guide the design and implementation of strategies to improve widespread POCT adoption.

Dissolved Barium Causes Toxicity to Groundwater Cyclopoida.

Barium (Ba) dissolution and mobilization in groundwater are predominantly controlled by sulfate because of the low solubility of barium sulfate (BaSO) minerals. Naturally present at low concentrations in groundwater, elevated concentrations of Ba can occur as a result of anthropogenic activities, including use of barite in drill operations, and geogenic sources such as leaching from geological formations. No toxicity data exist for Ba with groundwater organisms (stygofauna) to assess the risk of elevated Ba concentrations.

Preschooler Screen Time During the Pandemic Is Prospectively Associated With Lower Achievement of Developmental Milestones.

Objective: The aim of this study was to assess the developmental risks associated with total screen time, and specifically newer mobile devices, in the context of the pandemic.

Methods: This study uses parent-reported data from a prospective cohort of Canadian preschool-age children. The exposure variable is child daily screen time measured at the age of 3.
