Congestion pricing policies, carpool lanes, and new light rail train or subway infrastructure are all expensive, long-term ways for governments to battle traffic. A simpler solution, focused on human behaviour more than infrastructure, is convincing people to carpool.

Abstract:

Although significant research has examined how technology can intensify racial and other outgroup biases, limited work has investigated the role information systems can play in abating them. Racial biases are particularly worrisome in healthcare, where underrepresented minorities suffer disparities in access to care, quality of care, and clinical outcomes. In this paper, we examine the role clinical decision support systems (CDSS) play in attenuating systematic biases among black patients, relative to white patients, in rates of amputation and revascularization stemming from diabetes mellitus. Using a panel of inpatient data and a difference-in-difference approach, results suggest that CDSS adoption significantly shrinks disparities in amputation rates across white and black patients鈥攚ith no evidence that this change is simply delaying eventual amputations. Results suggest that this effect is driven by changes in treatment care protocols that match patients to appropriate specialists, rather than altering within physician decision making. These findings highlight the role information systems and digitized patient care can play in promoting unbiased decision making by structuring and standardizing care procedures.

Professor Sebastien Betermier sits down with the 91黑料网 Reporter to talk about sustainable investment strategies. According to Professor Betermier, progressive divestment strategies offer the best of both worlds for investors: they create positive environmental change while respecting the needs of all stakeholders.

However, for progressive strategies to be effective, Professor Betermier says that companies need to clearly communicate the strategy and set tangible milestones.

The聽91黑料网 Sustainability Systems Initiative is聽looking for big ideas in sustainability research from 91黑料网 faculty members based in the social sciences and humanities.

Solutions to sustainability challenges require much more than technological innovation, as viable plans to achieve sustainability must also address social and economic factors and conditions. For example, shifting society towards a more sustainable path will necessitate new norms, attitudes, habits, laws, economic incentives or instruments and public policies.

New research spearheaded by 91黑料网 has discovered that bacteriophages (viruses that infect bacteria) found in the intestinal tracts of children may play a role in childhood stunting, a significant impediment to growth that affects 22% of children under the age of five around the world.

Though they make up less than 6% of Earth鈥檚 surface, wetlands burst with biodiversity and play a key role in cleaning waterways, preventing floods, and sequestering carbon. For World Wetlands Day on February 2, researchers from 91黑料网 are launching interactive story maps to illustrate the valuable contributions these ecosystems make to our planet.
