Validating the Impact of Event Scale with Adolescents : a Look at the September 11, 2001, Terrorist Attacks

The current study examined the psychometric properties of the Impact of Event Scale (IES; Horowitz, Wilner, & Alvarez, 1979), a self-report measure of current subjective distress. Twenty-four adolescents from an urban high school were surveyed regarding their experiences from the events of September 11, 2001. The IES showed a moderate correlation with the My Worst Experience Scale (MWES; Hyman, Snook, Berna, & Kohr, 1997). Findings indicate the IES may be effective as a quick screening tool for the intrusive and avoidant symptoms of posttraumatic stress in adolescents pending further research with a larger sample

Local expansion method for fast plasma boundary identification in JET

ABSTRACT, A local expansion technique for the reconstruction of the plasma boundary is presented. The method is particularly accurate in identifying the separatrix in X-point configurations. It is applied to JET discharges and the results are compared with those of a full equilibrium code and with other independent diagnostics. It is found that the majority of the H-mode discharges at JET have been achieved in marginal limiter configurations. The method is sufficiently reliable and fast for real time shape control
