In response to the COVID-19 pandemic, public transport agencies across North America have made significant adjustments to services, including cutting trip frequency in many areas while increasing it in others. In many cases, these changes, especially service cuts, have disproportionately affected areas where lower-income and more vulnerable groups live, according to a new study from McGill University.
The Government of India's use of nudge theory in the first three months of the pandemic helped to tackle the virus on numerous fronts, a new study suggests.
People with atrial fibrillation who are exposed to greater levels of pollution have a higher risk of stroke than their peers who live with less pollution.
Researchers have compiled a new database of tweets from parliament members from 26 European countries and illustrated how this resource could help address challenges in the burgeoning field of Twitter research. Livia van Vliet of the University of Amsterdam, Netherlands, and colleagues present the new database and findings in the open-access journal PLOS ONE on September 16, 2020.
176,500 metric tons of synthetic microfibers--chiefly polyester and nylon--are released every year onto terrestrial environments across the globe, according to a new study in the open access journal PLOS ONE by Jenna Gavigan and colleagues at the University of California at Santa Barbara. The microfibers are shed from clothing during washing, and the amount ending up on land now exceeds the amount that enters waterbodies.
Researchers at UW Medicine found that primary-care physicians and rural clinic staff felt more skilled in delivering mental health care if they used a model known as collaborative care. In the model, primary-care physicians retain primary responsibility to treat behavioral health disorders with the support of two team members: a care manager (e.g., social workers, therapists, nurses) and a consulting psychiatrist.
This study looks at trends in out-of-pocket and total visit expenditures for visits to primary care physicians. Using the 2002-2017 Medical Expenditure Panel Survey (MEPS), the authors described changes in out-of-pocket and total visit expenditures for primary care visits for Medicare, Medicaid and private insurance. If current trends continue, the authors would expect increasing difficulty with primary care physician access, particularly for Medicaid patients.
The devastating effects of human activity on wildlife in the American tropics over the last 500 years are revealed in a new study published today. More than half of the species in local 'assemblages' - sets of co-existing species - of medium and large mammals living in the Neotropics of Meso and South America have died out since the region was first colonised by Europeans in the 1500s.
WSU study finds that when states turn to private prisons, the number of criminals incarcerated rises and the length of sentences increases. Private prisons lead to an average increase of 178 new prisoners per million population per year. At an average cost of $60 per day per prisoner, that costs states between $1.9 to $10.6 million per year, if all those additional prisoners are in private prisons.
Environmental hazards affect populations worldwide and can drive migration under specific conditions. Changes in temperature levels, increased rainfall variability, and rapid-onset disasters, such as tropical storms, are important factors as shown by a new study led by the Potsdam Institute for Climate Impact Research (PIK). Environmental migration is most pronounced in middle-income and agricultural countries but weaker in low-income countries, where populations often lack resources needed for migration.
