Latent fingerprint deposits on thermal paper sourced from the U.S., China, the U.K., and Australia have been visualized by heating. U.S. and Chinese sourced paper produced two distinct types of fingerprint development. In one type (type 1), the paper dye colors where the deposit is present (as previously reported) and in the other type (type 2) the ‘inverse’ of this gives paper coloring only in areas not coincident with the deposit. Both development types gave identifiable fingerprints, the majority fading within 24 h of heating. Fingerprint development from U.K. and Australian sourced paper was exclusively type 1 and resistant to fading. Temperatures for fingerprint visualization were higher for U.S. paper (64–71°C) and Chinese paper (75–95°C) than for U.K. and Australian sourced paper (43–50°C). Particularly for Chinese sourced paper, these temperatures were within a few degrees of the normal paper color temperature. A mechanism for type 2 fingerprint development is proposed.  相似文献

The Engage programme was launched in April 2006 by the Government Communication Network (GCN) in the UK. As a civil service body supporting those in government working as press officers and in marketing roles, the GCN under the New Labour government in the period 2006–2010 was involved with the extension of the logic of marketisation to government communication. This article charts this process by examining key government policy documents from this period. The rationale for Engage rested on the assumption that government in the UK needed to adapt its communication approach to reach what were perceived as individualised consumers in society. The extension of the logic of marketisation to government communication that happened under Engage is shown to be consistent with the New Public Management approach to public services under New Labour.

Product counterfeiting has grown in scope, scale and complexity in the last two decades, and now affects many areas of manufacturing and retailing from clothes and CDs to items such as shampoo and vehicle components. Based on a wide range of interviews in the UK, this article argues that despite recent legislative change and increased criminal penalties for counterfeiters, enforcement is haphazard, resource problems often dictate that no criminal prosecution is undertaken, and actual penalties remain low. Moreover, questions of whether or not a particular item is counterfeit have become greatly complicated by the development of outsourcing and the rise of parallel trading. These points suggest that counterfeiting is likely to grow in the future.  相似文献
