High above Saturn, new NASA image




A new iconic image from NASA?

High Above Saturn

This portrait looking down on Saturn and its rings was created from images obtained by NASA's Cassini spacecraft on Oct. 10, 2013. It was made by amateur image processor and Cassini fan Gordan Ugarkovic. This image has not been geometrically corrected for shifts in the spacecraft perspective and still has some camera artifacts.The mosaic was created from 12 image footprints with red, blue and green filters from Cassini's imaging science subsystem. Ugarkovic used full color sets for 11 of the footprints and red and blue images for one footprint.
The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington, D.C. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging operations center is based at the Space Science Institute in Boulder, Colo.

UMass Amherst Social Psychologists Say War is Not Inevitable

Photonic Positive is back posting after a prolonged summer break: much to catch-up.



Here is an article from Massachusetts University Amherst with an optimistic view that questions the need for war and the role psychological science can play.

 In a new review of how psychology research has illuminated the causes of war and violence, three political psychologists at the University of Massachusetts Amherst say this understanding can and should be used to promote peace and overturn the belief that violent conflict is inevitable.
Writing in the current special “peace psychology” issue of American Psychologist, lead author Bernhard Leidner, Linda Tropp and Brian Lickel of UMass Amherst’s Psychology of Peace and Violence program say that if social psychology research focuses only on how to soften the negative consequences of war and violence, “it would fall far short of its potential and value for society.”
“In summarizing psychological perspectives on the conditions and motivations that underlie violent conflict,” says Tropp, “we find that psychology’s contributions can extend beyond understanding the origins and nature of violence to promote nonviolence and peace.” She adds, “We oppose the view that war is inevitable and argue that understanding the psychological roots of conflict can increase the likelihood of avoiding violence as a way to resolve conflicts with others.”
Political leaders can be crucial in showing people different paths and alternatives to violent confrontation, the researchers point out. Leidner mentions Nelson Mandela, a leader who “offered South Africans an example of how to deal with the legacy of apartheid without resorting to further violence by making statements such as, ‘If you want to make peace with your enemy, you have to work with your enemy. Then he becomes your partner.’”
Leidner and colleagues recall how political and social psychology researchers have in recent decades steadily gained more understanding, through research, of such psychological factors as intergroup threat, uncertainty, group identity, emotions, moral beliefs and how intergroup conflict affects views of the world and of oneself.
They review theory and research that specify psychological factors that contribute to and perpetuate intergroup violence through emotional responses and belief systems fostered by conflict. Finally, they summarize ideas of how psychological “defenses of peace” –– a phrase in the United Nations Educational, Scientific and Cultural Organization (UNESCO) preamble –– can be constructed in the human mind.
The authors acknowledge that conflict and violence between groups persist because they often give people ways to address psychological needs, for identity, safety, security and power. Nonviolence has received far less media and research attention, they point out, but this should change. The UMass Amherst team urges social psychologists to consider factors that increase empathy and understanding of others, along with factors that increase the capacity for critical evaluation of the “ingroup.”
They conclude, “Research that investigates how to mitigate negative consequences of war and violence is valuable,” and the studies they summarize, grounded in “realistic insights,” support the view that psychology can be applied to promote peace. “It is our contention that psychology can and should be applied to promote peace, not war.”
The UMass Amherst Psychology of Peace and Violence Programwas launched in 2004 by a private endowment with matching university support. The only program of its kind in the United States, it uses scientific knowledge to resolve conflict between groups, promote reconciliation and build peace through cooperation. Faculty and students join a wide range of academic and community partners to decrease violence and promote peace through the application of research findings to real-world situations. The program hosts an international speakers series to bring peace and nonviolence research to the campus and local community.
