Forensic analysis of architectural finishes using Fourier transform infrared and Raman spectroscopy, Part I: The resin bases

The ability of Raman spectroscopy and Fourier transform infrared (FT-IR) microscopy to discriminate between resins used for the manufacture of architectural finishes was examined in a study of 39 samples taken from a commercial resin library. Both Raman and FT-IR were able to discriminate between different types of resin and both split the samples into several groups (six for FT-IR, six for Raman), each of which gave similar, but not identical, spectra. In addition, three resins gave unique Raman spectra (four in FTIR). However, approximately half the library comprised samples that were sufficiently similar that they fell into a single large group, whether classified using FT-IR or Raman, although the remaining samples fell into much smaller groups. Further sub-division of the FT-IR groups was not possible because the experimental uncertainty was of similar magnitude to the within-group variation. In contrast, Raman spectroscopy was able to further discriminate between resins that fell within the same groups because the differences in the relative band intensities of the resins, although small, were larger than the experimental uncertainty.

‘Ghosts in the Head and Ghost Towns in the Field: Ethnography and the Experience of Presence and Absence’

This article is about an anthropologist coming to terms with the field and fieldwork. In 1995, I left – was evacuated from – my fieldsite as a volcanic eruption started just as my period of fieldwork drew to a close. These eruptions dramatically and instantaneously altered life on the island of Montserrat, a British colony in the Caribbean. While Montserrat the land, and Montserratians the people, migrated and moved on with their lives, Montserrat and Montserratians were preserved in my mind and in my anthropological writings as from “back home.” Revisiting Montserrat several years into the volcano crisis, I drove through the villages and roads leading to the former capital of the island, where I had worked from. My route to this modern-day Pompeii threw up a stark contrast between absence and presence, the imagined past and the experienced present. This is understood, in part, by examining the literary work of two other travelers through Montserrat, Henry Coleridge and Pete McCarthy, both of whom have a very different experience of the place and the people.

'Democratic Transition, Judicial Accountability and Judicialisation of Politics in Africa: The Nigerian Experience'

Purpose – This paper aims to examine the growing incidence of judicialisation of politics in Nigeria’s democratisation experience against the backdrop of questionable judicial accountability. Design/methodology/approach – The article draws on legal and political theory as well as comparative law perspectives. Findings – The judiciary faces a daunting task in deepening democracy and (re) instituting the rule of law. The formidable challenges derive in part from structural problems within the judiciary, deficient accountability credentials and the complexities of a troubled transition. Practical implications – Effective judicial mediation of political transition requires a transformed and accountable judiciary. Originality/value – The article calls attention to the need for judicial accountability as a cardinal and integral part of political transitions.

From Empire to Iraq and the "War on Terror": The Transplanation and Commodification of the (Northern) Irish Policing Experience

Charting the enduring export appeal of policing models from (Northern) Ireland, this article sheds some light on the processes by which policing models are communicated and actively promoted to the global policing environment. The authors demonstrate how the transplantation of the Irish colonial model (ICM) represents an early example of the globalization of policing. The legacy of counterinsurgency expertise embedded within the ICM remains a historical constant and is a key factor in relation to the increasing commodification of the contemporary Northern Irish policing model, a model that successfully blends counterterrorism experience with a template for democratic policing reform. By juxtaposing these models, the authors provide a conceptual framework through which to assess the contemporary substance of policing transfer. The authors conclude by suggesting that the seductiveness of these policing models is largely attributable to lessons in counterinsurgency and notions of "Ireland as the solution" to a host of complex security scenarios.
