Large social networks foster connections by erasing national, geographic, and even linguistic barriers. But when it comes to fostering cooperation, global connectivity leaves something to be desired, new research says.
Working with colleagues at Emmanuel College, Harvard scientists have developed an algorithm that predicts whether a social structure is likely to favor cooperation, and the findings suggest that strong pairwise relationships — not loose networks scattered across the globe — are the most conducive to cooperation. The study is described in a March
Harvard University just announced the launch of its Data Science Initiative, a program to harness the vast expertise and innovations that are occuring in disciplines as diverse as medicine, law, policy, and computer science.
Hospitalized patients treated by physicians who order more or more expensive tests and procedures are just as likely to be readmitted or to die as patients treated by doctors who order fewer or less expensive tests, according to research led by Harvard Medical School and the Harvard T.H. Chan School of Public Health.
Researchers have long known that bias can have an impact on hiring, but a new Harvard study suggests that it may also affect workplace performance.
Co-authored by Amanda Pallais, the Paul Sack Associate Professor of Political Economy and Social Studies, the study, which is based on data collected from a French grocery store chain, found that minority workers were far less efficient in a handful of important metrics when working with biased managers.
That drop in performance, Pallais and co-authors Dylan Glover and William Pariente say, can create a self
Growing up in Mexico City as a self-proclaimed geek, Paola Villarreal first realized the power of data after she arrived at a public bike-share station and discovered that all the bikes were taken.
Villarreal, then 26 and a self-taught computer programmer, used information the bike-share program had posted online, albeit in an obscure format, to develop a mobile application. The app allowed her to check her phone for sites on the program’s citywide network that had bikes available. She shared the app with her friends, and before long it became so popular city
For evidence that algorithms have reshaped our most fundamental financial systems, look no further than the quiet floor of the New York Stock Exchange. Once a chaotic scene of shouting traders, the floor is used more today as a backdrop for television interviews than trades.
In the not so distant future, drivers, cashiers, even journalists may go the way of the floor trader, replaced by intelligent algorithms that can do the same job
Having an optimistic outlook on life — a general expectation that good things will happen — may help people live longer, according to a new study from the Harvard T.H. Chan School of Public Health.
The study found that women who were optimistic had a significantly reduced risk of dying from several major causes of death — including cancer, heart disease, stroke, respiratory disease, and infection — over an eight-year period, compared with women who were
