West Nile virus encephalitis

West Nile virus (WNV) is a mosquito-borne virus that has caused a large number of deaths in the United States since the first outbreak in New York City in 1998. The outbreak initially was limited to the northeast but has since spread across the entire continental United States. WNV causes a variety of clinical symptoms, but the most severe consequences result from central nervous system infection, resulting in meningitis, encephalitis, or meningoencephalitis. We present a case of a 62-year-old male with metastatic cancer, who died as a result of WNV encephalitis. This is followed by a discussion on the epidemiology of WNV and a detailed summary of the methods and resources available to make a diagnosis of WNV infection postmortem. The material presented in the discussion should provide the forensic pathologist with all the information necessary to make a diagnosis of WNV infection postmortem. If nothing else, the routine collection and storage of serum, cerebrospinal fluid, and tissue for every case can enable the forensic pathologist to make this diagnosis even in cases in which WNV is not suspected until after autopsy.     

Signature authentication by forensic document examiners.

We report on the first controlled study comparing the abilities of forensic document examiners (FDEs) and laypersons in the area of signature examination. Laypersons and professional FDEs were given the same signature-authentication/simulation-detection task. They compared six known signatures generated by the same person with six unknown signatures. No a priori knowledge of the distribution of genuine and nongenuine signatures in the unknown signature set was available to test-takers. Three different monetary incentive schemes were implemented to motivate the laypersons. We provide two major findings: (i) the data provided by FDEs and by laypersons in our tests were significantly different (namely, the hypothesis that there is no difference between the assessments provided by FDEs and laypersons about genuineness and nongenuineness of signatures was rejected); and (ii) the error rates exhibited by the FDEs were much smaller than those of the laypersons. In addition, we found no statistically significant differences between the data sets obtained from laypersons who received different monetary incentives. The most pronounced differences in error rates appeared when nongenuine signatures were declared authentic (Type I error) and when authentic signatures were declared nongenuine (Type II error). Type I error was made by FDEs in 0.49% of the cases, but laypersons made it in 6.47% of the cases. Type II error was made by FDEs in 7.05% of the cases, but laypersons made it in 26.1% of the cases.     

Digital citizenship? Narrative exchange and the changing terms of civic culture

This article explores the possibilities for new forms of ‘digital citizenship’ currently emerging through digitally supported processes of narrative exchange. Using Dahlgren's (Dahlgren, P. 2003. “Reconfiguring Civic Culture in the New Media Milieu.” In Media and the Restyling of Politics, edited by J. Corner, and D. Pels, 151–170. London: Sage; Dahlgren, P. 2009. Media and Political Engagement. Cambridge: Cambridge University Press.) circuit of ‘civic culture’ as a model for exploring the interlinking preconditions for new acts of citizenship, we discuss the contrasting outcomes of research at three fieldwork sites in the North of England – educational (a sixth form college), civil society (a community reporters' network) and social (a local club). Each site provided clear evidence of the elements of Dahlgren's circuit (some depending on the intensive use of digital infrastructure, others predating it), but there were also breaks in the circuit that constrained its effectiveness. A crucial factor in each case for building a lasting circuit of civic culture (and an effective base for new forms of digital citizenship) is the role that digital infrastructure can play in extending the scale of interactions beyond the purely local.     

‘In Vino Veritas’: Truth and Method in Vinogradoff's Historical Jurisprudence

Sir Paul Vinogradoff is widely regarded as the intellectual heir of Sir Henry Maine. As such, he is implicated with Maine in the failure of historical jurisprudence to displace Austinian positivism at the heart of English legal theory. Yet Vinogradoff was of a different generation and intellectual provenance from Maine. By examining the relationship between Vinogradoff's historical jurisprudence and the work of the celebrated German historian Theodor Mommsen, this article aims to reaffirm the distinctiveness of Vinogradoff's contribution to English jurisprudence. It finds at the core of that contribution a Germanic commitment to ‘science’ and ‘method’ that proves both a strength and a weakness in the common law world of the time, and so reflects something of the character of that broader world itself.
