Platform adoption in network markets

Fri, 04/10/2015 - 13:56
Strategic partnering has become commonplace when introducing innovations to systems markets. In standards battles, network affiliation has been used as a market signal to create confidence in a format's success. This paper's authors thus develop and test a model aimed at finding the right partners to sponsor an innovative technology.

Kindergartners who shared iPads in class scored higher on achievement tests

Fri, 04/10/2015 - 12:35
A promising study found that kindergartners in classes with shared iPads significantly outscored their peers on achievement tests who were in classes that had no iPads or classes with iPads for each student (1:1).

New insights into graphene and organic composites in electronics

Fri, 04/10/2015 - 12:35
Chemists have reviewed the potential for graphene-organic composite materials in electronics. The researchers show how organic semiconductors can be used to better process graphene, and to tune its properties for particular applications.

Graphene looking promising for future spintronic devices

Fri, 04/10/2015 - 12:33
Researchers have discovered that large area graphene is able to preserve electron spin over an extended period, and communicate it over greater distances than had previously been known. This has opened the door for the development of spintronics, with an aim to manufacturing faster and more energy-efficient memory and processors in computers.

Who's a CEO? Google image results can shift gender biases

Thu, 04/09/2015 - 18:31
A new study assesses how accurately gender representations in online image search results for 45 different occupations -- from CEO to telemarketer to engineer -- match reality. Exposure to skewed image results shifted people's perceptions about how many women actually hold those jobs.

Quantum physics: Hot and cold at the same time

Thu, 04/09/2015 - 18:30
Temperature is a statistical concept. Very small systems, consisting of a small number of particles, are not usually described statistically. Scientists have now measured how quantum systems reach a state with well defined statistical properties -- and surprisingly, they found out that quantum systems can have several temperatures at once. The connection between small quantum systems and large systems obeying the laws of classical physics is one of the big open questions in physics.

Why do people play violent video games? Storytelling and meaningful choices may play a part

Thu, 04/09/2015 - 16:04
A wealth of studies have shown that violent video games contribute to antisocial and aggressive behavior. But what makes those games appealing in the first place? One possibility is that storytelling plays a role, particularly if it lets players engage in meaningful choices. A new study suggests that non-violent video games that capitalize on such storytelling have prosocial benefits that could ultimately be helpful to clinical disorders such as autism.

Improving the quality of medical care using computer understanding of human language

Thu, 04/09/2015 - 16:03
How can computer-based analysis of free text -- the narrative comments found in medical records and expressed in everyday language or technical terminology - help improve the quality of medical care?

Genetic factors determine performance on Mathematics course

Thu, 04/09/2015 - 12:18
Researchers have found a statistically significant relation between the performance of university students on a mathematics course and exposure to testosterone in the womb.

Social consequences of digital inequality

Thu, 04/09/2015 - 12:18
Digital inequalities, defined broadly in terms of people’s internet usage, skills and self-perceptions, should be considered as important as the ‘traditional axes of inequality’ with which we are all familiar: race, class and gender, experts argue. These new forms of inequalities can of course combine with existing social inequalities – and even make them worse by ‘carrying over pre-existing differences in human capital into online settings’.

Quantum interference links the fate of two atoms

Thu, 04/09/2015 - 12:14
For the first time, physicists have achieved interference between two separate atoms: when sent towards the opposite sides of a semi-transparent mirror, the two atoms always emerge together. This type of experiment, which was carried out with photons around thirty years ago, had so far been impossible to perform with matter, due to the extreme difficulty of creating and manipulating pairs of indistinguishable atoms.

Online creep: Targeted ads may have opposite effect of marketers' intent

Wed, 04/08/2015 - 21:12
Online advertisements that target users based on their web browsing habits and other personal information have a negative impact on the person’s intent to purchase the product, a new study concludes. But the fact that users find this practice “creepy” runs counter to conventional wisdom among online marketing professionals.

What can brain-controlled prosthetics tell us about the brain?

Wed, 04/08/2015 - 16:46
The field of neuroprosthetics has grown significantly over the past two decades thanks to advancements in technology. A biomedical engineer working at the leading edge of the field contends that these devices are also opening a new portal for researchers to understand how the brain functions.

A digital field guide to cancer cells

Wed, 04/08/2015 - 16:46
Scientists are mapping the habits of cancer cells, turn by microscopic turn. Using advanced technology and an approach that merges engineering and medicine, a team has compiled some of the most sophisticated data yet on the elaborate signaling networks directing highly invasive cancer cells. Think of it as a digital field guide for a deadly scourge.

Inkjet-printed liquid metal could bring wearable tech, soft robotics

Wed, 04/08/2015 - 16:46
New research shows how inkjet-printing technology can be used to mass-produce electronic circuits made of liquid-metal alloys for 'soft robots' and flexible electronics.

A glass fiber that brings light to a standstill

Wed, 04/08/2015 - 14:26
Light has been slowed down by coupling atoms to glass fibers. This technology is an important prerequisite for a future worldwide quantum internet.

Overconfidence in new technologies can influence decision-making

Wed, 04/08/2015 - 14:07
Technological advances in recent decades have transformed most aspects of daily life, and technology now plays a major role in business and society. However, little is known about how perceptions of technology might influence decision-making. Now researchers have shown that people tend to overestimate the likelihood of new technologies' success; this overconfidence can influence important decisions, such as investment choices.

Encryption for everyone

Wed, 04/08/2015 - 13:03
In the wake of the revelations that intelligence agencies have been engaged in mass surveillance activities, both industry and society at large are looking for practicable encryption solutions that protect businesses and individuals. Previous technologies have failed in practice because they were too expensive or not user friendly enough.

Stroke classification system called TOAST is easy to use and effective

Tue, 04/07/2015 - 18:13
A stroke classification system called TOAST is easy to use and effective, neurologists report. TOAST is used to classify ischemic strokes, which are caused by blood clots and account for about 85 percent of all strokes. A wide range of diseases can cause blood clots in the brain. Establishing the most likely cause influences both short-term and long-term prognoses. It also affects treatment decisions, especially treatments to prevent recurrent strokes.

Why daring to compare online prices pays off offline

Tue, 04/07/2015 - 18:13
The sudden closures of big-box stores like Future Shop and Target may make it seem like online shopping is killing real-world stores. But shoppers are actually engaging in 'web-to-store' shopping -- buying offline after comparing prices online.
