Examining the research underlying the sentencing guidelines concept in Denver,Colorado: A partial replication of a reform effort

This paper examines the empirical basis for the criminal sentencing guidelines developed in Denver, Colorado. Unlike many other sentencing reforms, such guidelines have generally been developed out of an empirical analysis of past sentencing decisions, which identifies those variables most predictive of sentence. Empirical arguments, as a part of a reform effort, are often more persuasive than nonempirical arguments. However, when the analysis is inadequate or faulty, the resultant reform effort may be called into question.Presented in this paper is a reanalysis of the original data used to develop the Denver guidelines. Questions are raised regarding implications of extensive missing observations across cases and the resulting shrinkage of cases available for multivariate analyses. The original data is reanalyzed in both its original form and in a more complete form by estimating the missing data through a complex regression technique. Our analyses suggest that there are serious methodological weaknesses in the original study. The implications of these weaknesses are discussed.     

Detection of visible and latent fingerprints using micro-X-ray fluorescence elemental imaging

Using micro-X-ray fluorescence (MXRF), a novel means of detecting fingerprints was examined in which the prints were imaged based on their elemental composition. MXRF is a nondestructive technique. Although this method requires a priori knowledge about the approximate location of a print, it offers a new and complementary means for detecting fingerprints that are also left pristine for further analysis (including potential DNA extraction) or archiving purposes. Sebaceous fingerprints and those made after perspiring were detected based on elements such as potassium and chlorine present in the print residue. Unique prints were also detected including those containing lotion, saliva, banana, or sunscreen. This proof-of-concept study demonstrates the potential for visualizing fingerprints by MXRF on surfaces that can be problematic using current methods.     

Corruption in the North Sea oil industry: Issues and assessments

The article explores the extent, the institutional mechanisms and economic consequences of economically motivated bribery in the Norwegian (and British) oil industry. It focuses on corruption directed against middle-level management in the oil companies. The empirical part of the study is partly based on public information collected from court cases, mainly from British courts; and partly based on systematic interviews of security experts in Norwegian and international oil companies, and British and Norwegian police.     

Homicide-suicide (dyadic death), homicide, and firearms use in England and Wales

Homicide-suicide forms a distinct form of homicide. An analysis of cases in the Yorkshire and Humberside region of England between 1991 and 2005 revealed 37 episodes with 42 victims. Previous studies have shown a high rate of use of firearms. Over the last 2 decades firearms legislation has become more restrictive. In this study all assailants were male, mean age 46.8 years. The commonest method of homicide was strangulation (36%) with 16% killed by firearms. This is a reduction compared with a previous study in the same region. All killers who shot their victims killed themselves with firearms. There were no multiple killings with firearms in this study and no stranger killings. Hanging was the commonest method of suicide. During the same period the use of firearms as a method of homicide increased in England and Wales with handguns, the most common weapon. Nationally, suicide after homicide has remained at a similar rate over the half century and is an uncommon phenomenon. Firearms use remains low in both homicide and homicide-suicide episodes in England, and further analysis is required to determine changes in patterns of killing.
