Challenges Confronting Contemporary Public Budgeting: Retrospectives/Prospectives from Allen Schick

For nearly half a century, Allen Schick's works have explored and analyzed central issues in the role of budgets in modern government. In 2009, the Organisation for Economic Co‐operation and Development published Evolutions in Budgetary Practice: Allen Schick and the OECD Senior Budget Officials, a selection of his work, together with new chapters. The book traces developments in budget practices and reforms since the 1980s, relating them to changes in the role of government, and discusses challenges to contemporary budgeting and how they might be met. This collection provides an invaluable insight into Schick's thinking about public budgeting: a perspective on the past, a practical resource for the present, and a guide to the future.     

Forensic applications of infrared chemical imaging: multi-layered paint chips

This paper examines the potential of infrared chemical (hyperspectral) imaging as a technique for the forensic analysis of automotive paint chips in particular, and multicomponent (e.g., layered) samples in general. Improved sample preparation procedures for the infrared analysis of paint chips are detailed, with the recommendation that where mounting resins are chemically incompatible with the sample, it is better to mount and section the sample in a soft wax from which the sections can be removed and pressed into a KBr disk for transmission analysis. Infrared chemical images of multilayered paint chips have been successfully obtained, with the chief advantage over conventional infrared analysis being that thousands of infrared spectra are collected in a few minutes across the whole sample, at a spatial resolution of around 5 microm. As with conventional infrared spectroscopy, chemical species can be identified from their spectra, but the wealth of information available can be also extracted in a number of different ways that make multicomponent spectral (and hence chemical) comparisons between two samples easy to visualize and understand. In one approach, the infrared chemical images of two paint chips being compared side-by-side can be viewed as a "movie," in which each frame is an intensity map of the two samples at a given wavenumber (frequency) value. In another approach, the spectra (pixels) in the image files are classified into chemically similar groups, resulting in a "cluster" image that makes it possible to simultaneously compare all of the layers in two paint chips. These methods are applicable to other multicomponent samples, and also to other chemical imaging techniques.     

Raman spectroscopy and the forensic analysis of black/grey and blue cotton fibres Part 1: investigation of the effects of varying laser wavelength

Raman spectroscopy was investigated to determine the optimal conditions, mainly laser wavelength/s, for the analysis of the commonly encountered black/grey and blue cotton fibres dyed with reactive dyes. In this first part, a single blue cotton fibre, its three dye components, and an undyed cotton fibre were analysed with five different laser wavelengths from two different Raman microprobe spectrometers. The quality of the spectra, fibre degradation and speed of acquisition were used to determine that, under the conditions used, the 785 and 830 nm lasers gave superior results. The 632.8 nm laser wavelengths provided good results with little acquisition time and no spectral degradation. Results indicate that, at least, the major dye component could be identified using Raman spectroscopy.     

Wounding characteristics of glaser safety ammunition: a report of three cases

Handgun ammunition that contains multiple pellets (birdshot) comes in two forms. We describe here the autopsy and radiographic findings in three individuals who were fatally wounded with Glaser safety ammunition and contrast the findings to those reported in shot shell injuries.     

Female and male sex offenders: a comparison of recidivism patterns and risk factors

Few studies have empirically validated the assertion that female and male sex offenders are vastly different. Therefore, utilizing a matched sample of 780 female and male sex offenders in New York State, the current study explored differences and similarities of recidivism patterns and risk factors for the two offender groups. Results suggested that male sex offenders were significantly more likely than female sex offenders to be rearrested for both sexual and nonsexual offenses. However, limited differences in terms of risk factors between female and male sex offenders were found.
