Impact of Event Scale

The 15-item Child/Adolescent Impact of Events Scale (Horowitz, 1996) is also an easy-to-use instrument to identify core features of PTSD in children and adolescents, although it does not yield a formal diagnosis of PTSD.

The impact of IT security incidents to IT-enabled supply chains became evident as we analyzed the results of several industry surveys conducted to assess the impact of woridwide computer virus events over the past two years. The studies, done in cooperation with Cybertrust, the largest managed security services company in the world, were conducted to analyze the impact of large-scale virus events and included thousands of organizations worldwide. Although the scope of these instruments did not specifically address the source of infection, numerous respondents pointed to their partners as a source of infection in open response questions. We also noticed a number of organizations specifically commented on various impacts to their supply chain operations after partners were infected. Several examples of participant comments following four well-known viruses are included in Table 1. 

Figures 12 and 13 illustrate two of the more commonly used methods for displaying societal risk results (1) an F-N curve and (2) a risk profile. The F-N curve plots the cumulative frequencies of events causing N or more impacts, with the number of impacts (N) shown on the horizontal axis. With the F-N curve you can easily see the expected frequency of accidents that could harm greater than a specified number of people. F-N curve plots are almost always presented on logarithmic scales because of...

The visual and conceptual impact of seeing the timed sequence of structures, a full representation of atomic-scale events as a complex chemical reaction took place, was powerful. This achievement, the product of state-of-the-art calculations applied to an ambitious objective as well as excellent presentation graphics, was not diminished through a repressed awareness that it aU depended on theory. Nothing experimentally based provided an anchor for the visually compelhng rendition of the reacting system as a cyclopropane cleaved a C C bond, formed a trimethylene diradical intermediate, and executed a net one-center epimerization before reverting to the cyclopropane structure. 

Several episodes of volatile loss then followed in which the overall concentrations of all volatiles were reduced by one or two orders of magnitude. It is likely that this volatile loss took place through impact degassing and Porcelli et al. (2001) have proposed that this was the Moon-forming impact event, at ca. 30 Ma after t0. Impacting on this scale would have led to extensive melting and volatile loss from all the outer... 

It is not true that the QCM is blind to nonlinear interactions. The QCM measures a peculiarly weighted average of the force, but it certainly can access nonlinear phenomena via the amplitude dependence of A/ and AT. The QCM probes elastic and dissipative interactions at high frequencies. How relevant these high-frequency interactions are for real world devices, needs to be seen. We know today that things are much different at the MHz scale. We also know that fast processes are important in contact mechanics. Typical phenomena, where high-frequency events are crucial, are the sudden impact of a slider onto a substrate or the advancement of a crack tip in fracture events. At this point, the contact mechanics experiments with the QCM are part of fundamental research, but that may change. 

The large impact of ultramicroelectrodes is rooted in their ability to support very useful extensions of electrochemical methodology into previously inaccessible domains of time, medium, and space. That is, UMEs allow one to investigate chemical systems on time scales that could not previously be reached, in media that could not previously be employed, or in microstructures where spatial relationships are important on a distance scale relevant to molecular events.
