New big-data analytics by a City College of New York-led team suggests that both an individual's economic status and how they are likely to react to issues and policies can be inferred by their position in social networks. The study could be useful in maximizing the effects of large-scale economic stimulus policies.
A new study has found that children in Head Start who miss 10 percent or more of the school year have fewer gains in academics than their peers who attend preschool more regularly. Many researchers see high-quality preschool programs as a way to reduce long-term disparities in education. Placing an emphasis on attendance in preschool programs may be important to maximizing benefits.
Ebola outbreaks are set to be managed quickly and efficiently -- saving lives -- with a new approach developed by an international team of researchers, including the University of Warwick, which helps to streamline outbreak decision-making.
The warming climate has dramatically reduced the size of 39 glaciers in Montana since 1966, some by as much as 85 percent, according to data released by the U.S. Geological Survey and Portland State University. On average, the glaciers have reduced by 39 percent and only 26 glaciers are now larger than 25 acres, which is used as a guideline for deciding if bodies of ice are large enough to be considered glaciers.
A tipping point is a critical threshold at which a dynamical system undergoes an irreversible transformation, typically owing to a small change in inputs or parameters. A numerical simulations of tipping points did at the University of São Paulo's Physics Institute (IF-USP) in Brazil provide a better understanding of the characteristics of this point of no return and what happens to a system after its occurrence.
In classical computer science information is stored in bits, in quantum computer science -- in quantum bits, i.e. qubits. Experiments at the Institute of Physical Chemistry of the Polish Academy of Sciences in Warsaw prove that not only physics, but also chemistry is suitable for storing information. The role of the chemical bit, the 'chit', can be fulfilled by a simple arrangement of three droplets in contact with each other, in which oscillatory reactions occur.
Online user reviews have become an essential tool for consumers who increasingly rely on them to evaluate products and services before purchase. The business models of online review platforms like Yelp and TripAdvisor, and e-commerce sites like Amazon and Expedia critically depend on them. Should such sites pay users to encourage them to write reviews? According to a study in the INFORMS journal Marketing Science, a leading academic marketing journal, that is a bad idea.
After some serious number crunching, a UBC researcher has come up with a mathematical model for a viable time machine.
Scientists have identified thousands of previously ignored genetic mutations that, although rare, likely contribute to cancer growth. The findings, which could help pave the way to new treatments, are published in PLOS Computational Biology.
When we make a decision about whether or not to cooperate with someone, we usually base our decision on past experiences. However, when analyzing strategies for repeated dilemmas, modeling long-term memory in cooperative strategies quickly becomes computationally intractable. To overcome this challenge, scientists have distilled a set of axioms that every robust cooperative strategy should have. In this way, they reduce the computation necessary for an open-ended search of all possible strategies.
