GrinLine Identification Using Digital Imaging and Adobe Photoshop*

Abstract: The purpose of this study was to outline a method by which an antemortem photograph of a victim can be critically compared with a postmortem photograph in an effort to facilitate the identification process. Ten subjects, between 27 and 55 years old provided historical pictures of themselves exhibiting a broad smile showing anterior teeth to some extent (a grin). These photos were termed “antemortem” for the purpose of the study. A digital camera was used to take a current photo of each subject’s grin. These photos represented the “postmortem” images. A single subject’s “postmortem” photo set was randomly selected to be the “unknown victim.” These combined data of the unknown and the 10 antemortem subjects were digitally stored and, using Adobe Photoshop software, the images were sized and oriented for comparative analysis. The goal was to devise a technique that could facilitate the accurate determination of which “antemortem” subject was the “unknown.” The generation of antemortem digital overlays of the teeth visible in a grin and the comparison of those overlays to the images of the postmortem dentition is the foundation of the technique. The comparisons made using the GrinLine Identification Technique may assist medical examiners and coroners in making identifications or exclusions.     

Correlates of crime in Taiwan

Taiwan is known for rapid economic growth, but in 1988, the government ended 40 years of martial law, resulting in greater political and social freedoms. This paper explores the influence of economic, social, and political structures on crime in the Republic of China on Taiwan. A time series analysis examines the structural correlates of crime in Taiwan from 1964 to 1990. Both total crime and burglary/larceny rates are regressed on seven independent variables derived from various theoretical perspectives. The results support Hagan's power-control and Christie's crime-industry perspectives for total crime, while measures assessing lack of economic means and the economic deprivation were significant for burglary/larceny.
