Welcome to At the Intersections. This week, we examine the use of modeling to understand connections between our environment, actions, and well-being. We feature work that projects the financial outcomes of weather and the health consequences of workplace structure. Other pieces refine medical knowledge by assessing treatment safety during pregnancy, clarifying prevention strategies for specific populations of women, and tracing the effects of childhood habits. Finally, we look at a system where human expertise and artificial intelligence collaborate to process neural data.

Can an AI assistant help experts clean brainwave recordings?
|
|
|
Cleaning distorted signals from EEG brain activity recordings is a laborious and manual process for experts. This study developed a system where an AI agent assists experts to identify, label, and clean these signals in a repeating feedback loop.

Does treating hepatitis C during pregnancy increase risks for the developing fetus?
|
|
|
A key question for healthcare providers is whether it is safe to treat a person with hepatitis C virus during pregnancy to prevent the virus from being passed to their child. This work interprets data on maternal and fetal outcomes from a pharmacovigilance dataset and other clinical studies that tracked exposure to direct-acting antivirals.

What, besides hail size, determines the financial cost of a hailstorm?
|
|
|
This study addresses the challenge of modeling insured financial losses caused by hailstorms. To build empirical vulnerability functions, researchers modeled loss data from three Calgary hailstorms against environmental variables like hail size and precipitation, along with socioeconomic data from the Canadian Census.

How many sick days could giving young employees more influence at work prevent?
|
|
|
This research estimates the potential reduction in sickness absence among young Danish employees that could result from increasing their influence at work. The researchers used register data from 301,185 individuals, assigned an average level of influence based on job title, and then simulated an increase in this factor to predict its effect on sickness absence days.

Does the age you start gaming predict later gaming problems?
|
|
|
It is unclear whether the age at which a person starts playing video games frequently is connected to the severity of later problematic gaming symptoms. To investigate this, researchers used modeling to identify how different patterns of frequent gaming during early life relate to problematic gaming in adults.

How do post-exposure HIV prevention strategies for cis and trans women differ?
|
|
|
Post-exposure HIV prevention options for cis and trans women are understudied and underutilized, even as HIV prevalence in this group is increasing. To build a clearer understanding of these methods, researchers conducted a systematic search of scholarly literature and used a concept analysis to examine 33 relevant studies.
