The Measurand Problem in Breath Alcohol Testing

Proper interpretation of forensic measurements can be critical to the administration of justice. Breath alcohol testing is commonly relied upon to measure the concentration of alcohol in breath or, indirectly, in blood. The concentration sought constitutes the “quantity intended to be measured,” referred to as the measurand. Although breath tests always probe the same physical quantity, their measurand is dictated by statute and varies between jurisdictions. Thus, identical numerical values obtained from tests in disparate jurisdictions may refer to different quantities and may not indicate the relevant statutory measurand. This can lead to misinterpretation of results, referred to as the “measurand problem.” We first illustrate the concept of the measurand. Thereafter, the measurand problem is illustrated through application of Hlastala's breath test paradigm and Gullberg's work on breath test uncertainty. It is shown that where the measurand is not properly accounted for, conclusions based upon breath test evidence are undermined.     

Elite defection and grassroots democracy under competitive authoritarianism: evidence from Burkina Faso

One determinant of the success or failure of political revolutions is whether there is a split among the ruling elites. Elite defections in a competitive authoritarian regime can tip the balance in favour of regime change and democratization. This article examines when and why elites defect through the case of Burkina Faso. In October 2014, President Blaise Compaoré of Burkina Faso was forced to step down after 27 years in power and multiple term limits contraventions. We propose a new theory linking growth in democratic attitudes at the grassroots to elite defection from hegemonic parties. We argue that a broad increase in popular democratic attitudes can both decrease the costs and increase the benefits of elite defection, creating conditions that enable elites to rescind their loyalty to the regime. We support this argument with interviews with ruling-party defectors in Burkina Faso and two rounds of Afrobarometer survey data. Our findings demonstrate that democratic attitudes can grow under competitive authoritarian regimes, and that these citizen attitudes can impact regime change by increasing the likelihood of elite defection.     

Victim Blame in Fictional Crime Dramas: An Examination of Demographic,Incident-Related,and Behavioral Factors

How victims are portrayed in fictional crime dramas is an important way that individuals come to understand and interpret what it means to be a victim of crime. We examine how demographic variables (e.g., gender, race, age), incident variables (e.g., location of offense, relationship between victim and offender, type of crime), and behavioral variables (e.g., drug use/alcohol use, sexual promiscuity, negative personality traits, or concealing elements of personality) predict victim blame. Although some literature has analyzed victims in fictional crime dramas, such literature has been limited to a single year, a single show, a particular crime, or a particular factor. We extend this literature by focusing on multiple factors that predict victim blame using data collected from a systematic sample of 124 episodes from 4 fictional crime dramas (CSI, Law & Order: Special Victims Unit, Criminal Minds, and Without a Trace) over 7 years (2003–2010).     

Highly Sensitive Detection of Blood by Surface Enhanced Raman Scattering,,

Raman spectroscopy for forensic body fluid analysis has received some attention due to the nondestructive nature and potential application for identification at the crime scene; however, its usage has been limited by low detection sensitivity. Surface enhanced Raman scattering (SERS) was evaluated for blood identification for forensic applications. Specifically, a SERS‐active substrate was fabricated, composed of nickel nanotips coated with Ag nanoparticles. Compared with a conventional substrate, the SERS substrate enhanced Raman scattering by more than two orders of magnitude and allowed blood to be identified to a dilution of 1:100,000. Blood was also successfully detected by swabbing the SERS substrate directly on mock evidence. Most importantly, Raman spectra obtained by swabbing the SERS substrate on blood stains were free of luminescence even when blood was deposited on luminescent fabrics. The nondestructive character, simplicity of sample preparation, and high sensitivity make SERS a prime candidate for field and laboratory‐based blood identification.     

Towards a multimodal ethnohistorical approach: a case study of bookplates

ABSTRACT

This study uses four examples of bookplates printed in Edwardian Britain (1901–1914) to demonstrate how the adoption of an ethnohistorical approach to social semiotics can vastly strengthen multimodal analysis. It argues that situating choices of image, colour, typography and materiality in archival research and the broader sociohistorical context of the Edwardian period can help to uncover the external motivations for a bookplate’s structure. The case study reveals that bookplate designs were primarily influenced by the social status and wealth of owners, as well as the specific, well-established norms of the bookplate genre. It also highlights the significance of connecting semiotic choices to the traditions of Edwardian society and the ways in which meanings can shift over time. The findings demonstrate the importance of grounding hypotheses concerning the function and form of artefacts in concrete historical documents, in addition to the vast potential of this methodology for exploring other texts within a particular historical period.     

Of Time and Causality: A Simple Test of the Requirement of Social Capital in Making Democracy Work in Italy

Using survey data from The Civic Culture study, this research note revisits the idea that institutional development across the regions of Italy differs because of varying levels of social capital. The findings indicate that – according to the earliest survey data available from Italy – it is unlikely that differences in the development of regional institutions between the North and the South were a result of differences in social capital between the two regions. The article ultimately contends that social capital is likely to be important for institutional (and economic) development, but that (a) it does not appear to be a prerequisite for either and that (b) it can develop far more quickly than expected; this implies that impersonal trust and a participatory culture are not resources that societies must wait for several centuries to acquire, but that perhaps they can be fostered by the development of powerful democratic institutions.
