Dental hygiene students' matching accuracy when comparing antemortem dental radiographs and oral photographs to simulated postmortem WinID3® odontograms

Matching dental antemortem (AM) and postmortem (PM) data for human identification is especially challenging when the workforce is limited. Dental hygienists have served mass fatality incidents (MFIs) due to dental-related expertise. However, forensics within dental hygiene education and research on transferable skills is limited. This qualitative balance design study assessed senior dental hygiene students' match accuracy of simulated cases varying in dental identifiers based on AM full mouth series (FMS) radiographs and oral photographs to PM WinID3^® odontograms to demonstrate possible disaster victim identification (DVI) transferable skills gained during formal education. A convenience sample of senior dental hygiene students (n = 31) was presented information on WinID3^® interpretation, then presented with 5 mismatched cases and asked to visually interpret each to make 10 total matches; five based on AM FMS with simulated PM WinID3^® odontograms and five based on AM photographs with PM WinID3^® odontograms. Match accuracy scores ranged from 41.9% to 58.1% for cases with 1–10 identifiers, and 77.4% to 93.5% for cases with 11–40 identifiers. Accuracy when matching AM radiographs to PM odontograms versus AM photographs to PM odontograms was compared and revealed no statistical differences in match accuracy depending on image type (p = 0.388 to 1.000). Results of this pilot study suggests transferable match accuracy skills resulted from the participants' dental hygiene formal education. These baseline skills with additional specialized training support the rationale for dental hygienists serving on DVI teams. More research is needed in education and practice when preparing dental hygienists for forensic-based service.     

Operational oceanography in Indonesia

In 2005 Indonesian and European institutes joined to start the first step for the implementation of an Ocean Operational System in the Indonesian archipelago. The system will support the decision making process for the sustainable use of marine resources, providing useful information and added value products as well as a service for an improved management of the sea with high business impact to targeted groups as public authorities and commercial operators (coastal managers, fishermen, shipping companies). In this paper the System is shortly described with its potential benefits and economic and social impacts.

International comparisons of income levels and growth rates

Development literature contains the hypothesis that middle income countries grow faster than other countries. This proposition has been related to a second hypothesis of stages and rates of growth, as well as to an ‘automatic mechanism’ for the reduction of international income disparities. This article examines the relevant evidence and finds the propositions unsupported by either theory or empirical data.     

Informating policy and administration a comparative perspective on terrorism

The cliche that ‘one man's terroirist is another man' freedom fighter’ represents the major dilemma of anti-terrorism policymakers and administrators. The conceptual confusion is further complicated by the ideological orientations and policy interests of the observers. The comparative study of terrorism, however, has provided a conceptual underpinning and does provide the tools for sorting out the biases. This article compares the six principal models of political terrorism and suggests that each in fact describes a distinct form of political violence depending upon the perspective of the observer. Each of the forms of terrorism, moreover, may require a unique set of remedies. Using the widely publicized TWA bijacking during the summer of 1985 as an example, the analysis examines the differences in the American, Israeli, and Lebanese government perspectives and how those differences influenced policymaking.
