India’s COVID-19 lockdown is widely believed to have disrupted critical health services, but its effect on non-COVID health outcomes is largely unknown. Comparing mortality trends among dialysis patients in the eight months around the lockdown with the previous year, we document a 64% increase in mortality between March and May 2020 and an estimated 22-25% total excess mortality through July 2020. The mortality increase is greater among females and disadvantaged groups.
Epidemiological modeling has emerged as a crucial tool to help decision-makers combat COVID-19, with calls for non-pharmaceutical interventions such as stay-at-home orders and the wearing of masks. But those models have become ubiquitous and part of the public lexicon — so Nirav Shah and Jason Wang write that they should follow an impact-oriented approach.
Cardiovascular disease is the leading cause of death among women in the U.S. and identification of sex-specific risk factors could enhance cardiovascular risk assessment and prevention. Pregnancy is an exposure unique to women: 85% of women give birth at least once in their lives, and up to 30% may experience an adverse pregnancy outcome (APO).
Where is nuclear arms control—negotiated restraints on the deadliest weapons of mass destruction—headed? This 50-year tool of US national security policy is currently under attack. The New Strategic Arms Reduction Treaty (New START), the last remaining nuclear arms agreement with the Russian Federation, will go out of force in February 2021 unless it is extended for an additional five years as the treaty permits. At this moment, nothing is on the horizon to replace it, though the Trump administration has promised a new and more extensive agreement that includes China as well as Russia.
Voluntary physical distancing is essential for preventing the spread of COVID-19. We assessed the role of political partisanship in individuals’ compliance with physical distancing recommendations of political leaders using data on mobility from a sample of mobile phones in 3,100 counties in the United States during March 2020, county-level partisan preferences, information about the political affiliation of state governors, and the timing of their communications about COVID-19 prevention.
High resolution satellite imagery and modern machine learning methods hold the potential to fill existing data gaps in where crops are grown around the world at a sub-field level. However, high resolution crop type maps have remained challenging to create in developing regions due to a lack of ground truth labels for model development. In this work, we explore the use of crowdsourced data, Sentinel-2 and DigitalGlobe imagery, and convolutional neural networks (CNNs) for crop type mapping in India.
Nineteen years after the terrorist attacks of September 11, 2001, does al Qaeda still pose a significant threat to U.S. national security? Among researchers, military and intelligence officials, and policymakers who study the group, there is little consensus. But very few experts on Salafi-jihadi movements would dismiss the group outright. So when U.S. Secretary of State Mike Pompeo confidently declared in a March interview on Fox & Friends that “al Qaeda is a shadow of its former self,” we were startled and concerned.
Over the past two decades, U.S. and Chinese technological trajectories have been closely linked. Internet protocols, hardware design and manufacturing, software development and deployment, and services and standards have to varying degrees been crossborder phenomena, with China and the United States two of the world’s most consequential and integrated countries. The last few years, however, have seen a rise in mutual suspicion and moves—both direct and indirect—to unwind this extraordinary level of technological interdependence.
Stanford Health Policy’s Joshua Salomon, a professor of medicine and senior fellow at the Freeman Spogli Institute for International Studies, and colleagues developed a mathematical model to examine the potential for contact tracing to reduce the spread of the coronavirus.
A growing number of countries have established programs to attract immigrants who can contribute to their economy. Research suggests that an immigrant's initial arrival location plays a key role in shaping their economic success. Yet immigrants currently lack access to personalized information that would help them identify optimal destinations. Instead, they often rely on availability heuristics, which can lead to the selection of sub-optimal landing locations, lower earnings, elevated outmigration rates, and concentration in the most well-known locations.
In a recent perspective published by the New England Journal of Medicine(NEJM), Stanford Law student Alexandra Daniels analyzed a growing body of federal litigation brought by prisoners with the hepatitis C virus (HCV) who are seeking access to treatment for their condition.
There is general consensus among experts that K-12 schools should aim to reopen for in-person classes during the 2020-2021 school year. Globally, children constitute a low proportion of coronavirus disease 2019 (COVID-19) cases and are far less likely than adults to experience serious illness. Yet, prolonged school closure can exacerbate socioeconomic disparities, amplify existing educational inequalities, and aggravate food insecurity, domestic violence, and mental health disorders. The American Academy of Pediatrics (AAP) recently published its g
