Recovery of Spray Paint Traces from Clothing by Beating

Manual recovery of spray paints from textiles using a microscope, the routine method in many laboratories, is often laborious. Beating the clothing with a plastic rod, the routine method used for recovery of glass traces within the authors’ laboratory, is proposed as an alternative. The efficiency of the method was evaluated by spray tests with fluorescent paint. In these tests, paint particles in the acquired debris samples, as well as those remaining on the textiles, were investigated. The results show that beating is an efficient way to recover and concentrate paint particles. A good efficiency for jeans fabric and rough knitwear is reported. The results appeared to be less satisfactory for smooth woven fabric. Application of the method in casework was effective for graffiti paints as well as for flaked car paint.     

Visualization of Latent Blood Stains Using Visible Reflectance Hyperspectral Imaging and Chemometrics

The detection of latent traces is an important aspect of crime scene investigation. Blood stains on black backgrounds can be visualized using chemiluminescence, which is invasive and requires a darkened room, or near-infrared photography, for which investigators need to change filters manually to optimize contrast. We demonstrated the performance of visible reflectance hyperspectral imaging (400–720 nm) for this purpose. Several processing methods were evaluated: single wavelength bands, ratio images, principal component analysis (PCA), and “SIMPLe-to-use Interactive Self-modeling Mixture Analysis” (SIMPLISMA). Using these methods, we were able to enhance the contrast between blood stains and 12 different fabrics. On black cotton, blood dilutions were visible with a minimal concentration of 25% of whole blood. The hyperspectral camera system used in this study is portable and wireless, which makes it suitable for crime scene use. The described technique is noncontact and nondestructive, so all traces are preserved for further analysis.     

Market offenses and limits to growth

The purpose of this article is to explore various factors that may regulate or stabilize levels in market offenses. Instead of assuming that illegal markets are ‘out of control’, evidence is advanced to demonstrate, on the contrary, that there are indeed limits to growth in criminal markets. This is presented along three principal and interconnected arguments. First, social norms limit the ability of suppliers to shape demand for illicit goods and services. Using public opinion surveys, it is concluded that the more objectionable the moral status of an illegal market, the smaller the pool of potential consumers and sellers. Second, there are considerable obstacles that confront suppliers of illegal goods and services accumulating capital and upward mobility. The consequences of product illegality inhibit the organizational growth capacities as well as the geographic expansion of illicit firms. Third, while impunity via corruptible alliances do cancel some of the effects of product illegality, this impunity is not a constant that can always be depended upon. To the extent that corruption varies across jurisdictions and over time, illegal entrepreneurs may come to realize that impunity is intrinsically limited in scope and volatile in nature and over which they essentially have very limited control.

Terrorism,Agenda 2063 and the challenges of development in Africa

The nobility of the objectives and aspiration of the African Union's Agenda 2063 towards the developmental needs of the African people are laudable, as are the attempts being made to ensure collective action, despite the ‘shield of sovereignty behind which too many corrupt leaders have hidden’. However, these noble objectives and aspirations may be undermined and threatened by the upsurge in militant Islamism and the spread of terrorism within and outside Africa, a fact not being addressed by Agenda 2063. Yet while Agenda 2063 does not seek to address the challenges posed by terrorist networks within the continent, which are threatening human security as well as the sovereignty, territoriality, legitimacy and stability of political regimes, these issues are at the core of the agenda. This article argues for Agenda 2063 to step up its efforts to combat both the roots of terrorism and the threat to development that terrorism itself poses.     

The Regionalisation of Judicial Review: Constitutional Authority,Access to Justice and Specialisation of Legal Services in Public Law

Since April 2009 judicial reviews may be dealt with at regional centres and in Cardiff. This change significantly relaxed the hitherto highly centralised system of judicial review in England and Wales. The main aims were to improve access to public law redress by enabling cases to be listed and heard at the most appropriate regional location. Despite recognition of the need to improve regional access, fears exist that this reform will threaten the standing and authority of judicial review in this jurisdiction; that it will contribute to a fragmentation of judicial review and, in the regions, reduce the quality of public law adjudication, legal advice and representation. Drawing on an empirical study on the regional use of judicial review, this paper assesses these matters and considers the early effects of regionalisation on access to judicial review and the development of regional markets for legal services in public law.     

Maintaining programme integrity: the FOR . . . A Change programme and the resettlement of ex-prisoners

This article describes the process and results of monitoring the programme integrity of FOR . . . A Change, a group programme for offenders, as it was being delivered in three prisons in the United Kingdom. In so doing, it briefly describes the aims, structure, and theoretical orientation of the programme; explains what informed the particular approach to checking for integrity and how it was implemented; outlines the results; and finally, postulates the requisite conditions for the successful maintenance of programme integrity.     

Red tape and technology transfer in US government laboratories

The purpose of this paper is to gauge the effects of red tape and bureaucratization on the technology-transfer activities and effectiveness of government laboratories in the United States. Two central questions are addressed: Do laboratories involved significantly in technology transfer have more red tape than others? and Does the level of red tape have an effect on technology-transfer success? Objective and perceptual measures of red tape are used. Technologytransfer effectiveness is measured in terms of getting other organizations to adopt technology developed in the laboratory (“out the door” success) and of the commercial impact of transfers. Data are derived from questionnaire responses provided by directors of 276 federal- and state-government laboratories. Results indicate that laboratories involved in technology transfer do not have higher levels of red tape. Out-the-door technology-transfer success relates strongly to low degrees of perceived red tape, whereas high ratings for commercial impact are associated with actual low levels of red tape in acquiring project funding and lowcost equipment.
