The evidential value of cosmetic foundation smears in forensic casework

Cosmetic foundation products are easily transferred to clothing and other surfaces as a result of contact with such objects. Examination of past cases involving cosmetics in New Zealand has shown cosmetic foundation to be one of the more common cosmetic products encountered. The aim of this research was to determine the most discriminating method for the comparison of transferred foundation with samples obtained from a known source in forensic casework. Fifty-three foundation samples were analyzed by Fourier transform infrared spectroscopy (FTIR), gas chromatography with a flame ionization detector (GC-FID) and scanning electron microscopy-energy dispersive X-Ray analysis (SEM-EDX). It was found that a 5 mm2 section of a light smearing was enough to provide detectable results. The discriminating powers for FTIR, SEM-EDX and GC-FID were 98.3, 93.8, and 82.0% respectively. A combination of all three techniques provided a discriminating power of 99.7%, meaning that almost complete discrimination was achieved between the foundation samples.     

Background correction in forensic photography. I. Photography of blood under conditions of non-uniform illumination or variable substrate color--theoretical aspects and proof of concept

The combination of photographs taken at two or three wavelengths at and bracketing an absorbance peak indicative of a particular compound can lead to an image with enhanced visualization of the compound. This procedure works best for compounds with absorbance bands that are narrow compared with "average" chromophores. If necessary, the photographs can be taken with different exposure times to ensure that sufficient light from the substrate is detected at all three wavelengths. The combination of images is readily performed if the images are obtained with a digital camera and are then processed using an image processing program. Best results are obtained if linear images at the peak maximum, at a slightly shorter wavelength, and at a slightly longer wavelength are used. However, acceptable results can also be obtained under many conditions if non-linear photographs are used or if only two wavelengths (one of which is at the peak maximum) are combined. These latter conditions are more achievable by many "mid-range" digital cameras. Wavelength selection can either be by controlling the illumination (e.g., by using an alternate light source) or by use of narrow bandpass filters. The technique is illustrated using blood as the target analyte, using bands of light centered at 395, 415, and 435 nm. The extension of the method to detection of blood by fluorescence quenching is also described.

The Electoral Impact of Constituency Campaigning in Britain, 1992–2001

Political parties maintain local organisations and recruit members mainly to fight elections. For most of the post-war period, however, the dominant view among analysts has been that constituency campaigning in British general elections has little or no effect on election outcomes. This view has been challenged over the last ten years or so. Evidence derived from post-election surveys of constituency election agents following the 1992, 1997 and 2001 general elections is used here to show that the intensity of constituency campaigning significantly affects turnout levels and, for Labour and the Liberal Democrats, levels of party support. There is also some evidence that Conservative campaigning affected constituency variations in the party's performance in 2001. The conclusions reached on the basis of aggregate-level analysis are supported by analysis of individual-level data derived from British Election Study surveys. The effects of campaigning are not large, but they are clear and significant – and sufficient to affect the numbers of seats won by the major parties. In the light of this, parties have good reasons to maintain healthy local organisations.     

Exploring Variations in Turnout: Constituencies and Wards in the Scottish Parliament Elections of 1999 and 2003

Elections for the Scottish Parliament and for all Scottish local authorities were held on the same day in 1999 and 2003, allowing a more detailed exploration of turnout variations than has been possible before. On both occasions, turnout in the two sets of elections was almost identical so that reported ward turnout at local level also indicates ward turnout in the parliament elections. Parliamentary turnout is analysed at both constituency and ward levels. The latter gives us greater confidence in the constituency results and also suggests some relationships which are not apparent at constituency level. The strongest determinant of turnout is consistently found to be the proportion of adults with a degree; religious affiliation, here analysed for the first time at the aggregate level, is also strongly related to turnout.
