Evaluation of canine training aids containment for homemade explosive and components by headspace analysis and canine testing

While canines are most commonly trained to detect traditional explosives, such as nitroaromatics and smokeless powders, homemade explosives (HMEs), such as fuel–oxidizer mixtures, are arguably a greater threat. As such, it is imperative that canines are sufficiently trained in the detection of such HMEs. The training aid delivery device (TADD) is a primary containment device that has been used to house HMEs and HME components for canine detection training purposes. This research assesses the odor release from HME components, ammonium nitrate (AN), urea nitrate (UN), and potassium chlorate (PC), housed in TADDs. Canine odor recognition tests (ORTs) were used with analytical data to determine the detectability of TADDs containing AN, UN, or PC. Headspace analysis by gas chromatography/mass spectrometry (GC/MS) with solid-phase microextraction (SPME) or online cryotrapping were used to measure ammonia or chlorine, as well as other unwanted odorants, emanating from bulk AN, UN, and PC in TADDs over 28 weeks. The analytical data showed variation in the amount of ammonia and chlorine over time, with ammonia from AN and UN decreasing slowly over time and the abundance of chlorine from PC TADDs dependent on the frequency of exposure to ambient air. Even with these variations in odor abundance, canines previously trained to detect bulk explosive HME components were able to detect all three targets in glass and plastic TADDs for at least 18 months after loading. Detection proficiency ranged from 64% to 100% and was not found to be dependent on either age of material.     

The Dynamics of State Policy Liberalism, 1936–2014

Applying a dynamic latent‐variable model to data on 148 policies collected over eight decades (1936–2014), we produce the first yearly measure of the policy liberalism of U.S. states. Our dynamic measure of state policy liberalism marks an important advance over existing measures, almost all of which are purely cross‐sectional and thus cannot be used to study policy change. We find that, in the aggregate, the policy liberalism of U.S. states steadily increased between the 1930s and 1970s and then largely plateaued. The policy liberalism of most states has remained stable in relative terms, though several states have shifted considerably over time. We also find surprisingly little evidence of multidimensionality in state policy outputs. Our new estimates of state policy liberalism have broad application to the study of political development, representation, accountability, and other important issues in political science.     

The power of “small business” as pending narrative: an ideograph in UK politics 2004–2013

This paper explores utilisation of the term small business in contemporary politics in the United Kingdom. First, the policy and practice implications of the term small business are examined, through the lens of political rhetoric. Use of the term over the period from 2004 to 2013 is examined, drawing upon the DataArt Guardian NewsTraces platform as both a method of initially visualising an overall pattern of the term’s use during the 10-year period, and a medium for facilitating data collection for analysis. The research question is: how is the term “small business” used in political rhetoric in the UK, in the identification of policy problems and solutions, and the creation of pending narrative? It is determined that the term small business is an ideograph with different and often competing meanings for various interest groups, and suffers from serious imprecision despite policy efforts which strive for legitimacy. Even with spikes in use reflecting election cycles and periods of economic stress, the term’s power is in its mutable but appealing vagueness, and its enduring quality as pending narrative. This leaves open obvious questions of both policy efficacy and the sufficiency of ideographic-laced rhetoric as a substitute for meaningful policy.     

Enhancing Precision and Clarity in the Study of Policy Narratives: An Analysis of Climate and Air Issues in Delhi,India

The study of policy narratives is challenged by inconsistencies and a need for more precise definitions and measurements. The goals of this article are to build precision and clarity in the study of policy narratives by developing a network‐based approach—the ego‐alter dyad—for coding characters and their interactions around a policy issue and then to illustrate this approach in the analysis of air and climate issues in Delhi, India. The empirical results show that (1) the same actors are often heroes and villains, (2) heroes and villains are associated with different actions but with similar victims or beneficiaries, (3) narrators differ in their propensity to tell hero‐heavy or villain‐heavy policy narratives, and (4) the proportion of hero‐heavy or villain‐heavy policy narratives changes over time and differs across subtopics. The article concludes with a research agenda for further theoretical and methodological advancement in studying policy narratives.     

Contested Governance: Understanding Justice Interventions in Post-Qadhafi Libya

ABSTRACT

This contribution reflects upon the nexus between transitional justice and peacebuilding through a study of how transitional justice practices in post-Qadhafi Libya interacted with broader efforts to establish governance institutions in the aftermath of Libya’s 2011 armed conflict. It argues that dominant practices of transitional justice, promoted by external actors, prescribed narrow state-centric justice interventions that were ill-suited for a polity in which the state was highly contested. In fact, transitional justice proved divisive in Libya because attempts to project state-centric liberal justice practices were limited by their targeting of weak institutions that lacked local legitimacy and their inability to reconcile alternative normative frameworks that challenge the modern state. In addition, the weakness of Libya’s state institutions allowed thuwwar, or revolutionary armed groups, to dictate an exclusionary form of justice known as political isolation. Drawn from fieldwork conducted in Libya, this contribution provides lessons for both peacebuilding and transitional justice practice that call for a rethinking of teleological notions of transition and greater engagement with notions and concepts that fall outside dominant practices.     

From Rebels to Rulers: The Challenges of Transition for Non-state Armed Groups in Mindanao and Myanmar

This article presents a critical comparison of the ongoing peace processes in the southern Philippines and Myanmar (Burma). It does so by examining two key armed groups: the Moro Islamic Liberation Front (MILF) on Mindanao, and the Karen National Union (KNU) in Myanmar. We identify common elements that help to explain the relative – albeit incomplete – success of these two groups in navigating their respective peace processes. The MILF and KNU are ethnonationalist armed groups struggling for self-determination against states that are experienced by ethnic minority communities as culturally alien, and economically and politically dominant. Both conflict actors are characterized by complex combinations of “greed” and “grievance” factors but nevertheless enjoy significant (albeit contested) political legitimacy among the communities they seek to represent. We explore the complex relationships between armed ethnic groups, conflict-affected communities, and civil society actors. We argue that engagement with civil society is a key element of success in the Mindanao peace process, which could be replicated in Myanmar. We examine the roles and changing nature of the state in the Philippines and Myanmar, and contrast the degrees of international involvement, as key variables in these peace processes. We observe that negotiations of comprehensive peace settlements are threatened by “the tyranny of elections” in Myanmar (2015) and the Philippines (2016), and observe the importance of including national parliaments in peace processes in a timely manner. The peace process between Manila and the MILF represents a rare example of a Muslim minority pursuing its political objectives through structured dialogue. The article focuses on the challenges faced by armed groups moving from insurgency to reinvent themselves as credible political actors and governance authorities. Our analysis draws on peace-building literature, specifically the phenomenon of “rebel governance.”
