YouTube Campaign Videos More Positive Than Television Ads

ANN ARBOR, Mich.—YouTube campaign videos are more positive than ads aired on television, a new University of Michigan study shows.

YouTube videos are more positive because they are narrowly targeted to the highly informed, high motivated, usually supportive people who view a candidate’s online video, said Rob Salmond, the study’s author and assistant professor of political science. (more…)

Picture Worth a Thousand Numbers: New Data Visualization Tool Helps Find the “Unknown Unknowns”

A research team at the Georgia Tech Research Institute (GTRI) has developed a software tool that enables users to perform in-depth analysis of modeling and simulation data, then visualize the results onscreen. The new data analysis and visualization tool offers improved ease of use compared to similar tools, the researchers say, and could be readily adapted for use with existing data sets in a variety of disciplines.

U of T Research Demonstrates How Children Learn About Prejudice

How do children come to realize that they themselves might be targets of prejudice? It may depend on their age. New research conducted at the University of Toronto shows that a six-year-old may be influenced most by direct instruction about prejudice, but once that child gets closer to 10, she begins to rely more on her own experiences.

“Young children are information hungry – they are eagerly searching for general rules to help in mapping out their social worlds,” write researchers Sonia Kang, an assistant professor in the Department of Management at U of T Mississauga and the Rotman School of Management, and Professor Michael Inzlicht of the Department of Psychology in this month’s Personality and Social Psychology Bulletin.

New Understanding of Earth’s Mantle Beneath The Pacific Ocean

Washington, D.C. — Scientists have long speculated about why there is a large change in the strength of rocks that lie at the boundary between two layers immediately under Earth’s crust: the lithosphere and underlying asthenosphere. Understanding this boundary is central to our knowledge of plate tectonics and thus the formation and evolution of our planet as we know it today. A new technique for observing this transition, particularly in the portion of Earth’s mantle that lies beneath the Pacific Ocean basin, has led Carnegie and NASA Goddard scientist Nick Schmerr to new insight on the origins of the lithosphere and asthenosphere. His work is published March 23 in Science.

The lithosphere-asthenosphere boundary, or LAB, represents the transition from hot, convecting mantle asthenosphere to overlying cold and rigid lithosphere. The oceanic lithosphere thickens as it cools over time, and eventually sinks back into the mantle at Earth’s so-called subduction zones. (more…)

Study of Patagonian Glacier’s Rise and Fall Adds to Understanding of Global Climate Change

Glaciers play a vital role in Earth’s climate system, and it’s critical to understand what contributes to their fluctuation.

Increased global temperatures are frequently viewed as the cause of glacial melt, but a new study of Patagonia’s Gualas Glacier highlights the role of precipitation in the glacier’s fluctuation. The study, conducted by Sébastien Bertrand of the Woods Hole Oceanographic Institution (WHOI) and his colleagues, reconstructs a 5,400 year-record of the region’s glacial environment and climate, comparing past temperature and rainfall data with sediment records of glacier fluctuations and the historical observations of early Spanish explorers.
