Trace elements in clinopyroxenes from Aleutian xenoliths: Implications for primitive subduction magmatism in an island arc
Trace element abundances in clinopyroxene (cpx) from cumulate xenoliths are used to characterize the nature of primitive magma-forming processes beneath the Aleutian island arc. Clinopyroxenes from deformed mafic and ultramafic xenoliths hosted in a Neogene-age mafic sill from Kanaga Island have widely varying trace element abundances (Sr=8–32, Y=2–64, Zr=2–38, Nd=0.65–16 ppm) that are generall...
متن کاملIncentives to Share Knowledge
The knowledge required for decision making in a firm is distributed across various departments. In practice cross functional teams are used to integrate this distributed knowledge. Incentive schemes are of crucial importance to encourage departments to share knowledge. In this paper, we study different incentive schemes by means of a two stage model. In the first step departments have to choose...
متن کاملTo Share or Not to Share? Professional Norms, Reference Groups, and Information Withholding Among Life Scientists
Why do scientists withhold information from colleagues, violating the professional norm of sharing? Norm violations are usually attributed to individual interests that lead scientists to reject professional norms. In contrast, we take the view that norm violations can occur when professional norms are valued but it is difficult to ascertain the appropriate course of professional conduct. This v...
متن کاملSensor-Internet Share and Search—Enabling Collaboration of Citizen Scientists
Over the last decade, embedded sensing systems have been successfully deployed in a range of application areas, from education and science to military and industry. These systems are becoming more robust, capable, and widely adopted. Yet today, most sensor networks function in isolated patches, each with different mechanisms to deliver data to their users, and often have no formal methods to sh...
متن کاملTeachers’ knowledge about epilepsy
Background and Purpose: Epilepsy is a disease frequently seen among school children. Teachers may be distressed by children having seizures as they do not receive specific training about this condition during their education. Moreover, teachers can feel overwhelmed if they do not know how to handle the situation. After cerebral apoplexy, epilepsy is the second most common central nervous system...
