The isolation of spermatozoa from sexual assault swabs using proteinase K

The most common examination in sexual offences is the identification of spermatozoa in aqueous extracts from swabs. Using Proteinase K with sodium dodecyl sulphate, it is possible to digest all the cellular material apart from the spermatozoa, resulting in a quick and effective method of their isolation. Spermatozoa were detected in 18 extracts using this treatment when the normal method had failed to reveal all but one of them.     

Performing blackness in the “Rainbow Nation”: Athi-Patra Ruga’s The Future White Women of Azania

This article applies Saidiya Hartman’s framework of performing blackness to South African performance artist Athi-Patra Ruga’s performance series, The Future White Women of Azania, to consider the ways in which the performances index the convoluted imbrications of colonialism, specifically Apartheid policy in South Africa, and postcolonialism, specifically the anti-Apartheid struggle(s) and the current political and economic structure of South African democracy. It argues that Ruga’s performance makes evident political and economic systems that tout black and queer liberation while perpetuating black queer death. Ruga’s work also relocates Hartman’s framework to a transnational, postcolonial context, expanding the notion of performing blackness (and the entangled processes of domination and subordination that it maps) beyond the trans-Atlantic paradigm, suggesting that performing blackness could be used to understand the correlation between broader spatial and temporal phenomena that shape blackness. Finally, situating The Future White Women of Azania as not only a performance of blackness, but of queerness as well, postulates that layering sexuality onto Hartman’s model reveals that the dynamics articulated under performing blackness are evident between oppressors and oppressed and between members of each of these groups as Hartman notes, but also between the contingent axes of subjectivity within an individual’s experience.     

The ideological nationalization of partisan subconstituencies in the American States

Since the mid-twentieth century, elite political behavior in the United States has become much more nationalized. In Congress, for example, within-party geographic cleavages have declined, roll-call voting has become more one-dimensional, and Democrats and Republicans have diverged along this main dimension of national partisan conflict. The existing literature finds that citizens have only weakly and belatedly mimicked elite trends. We show, however, that a different picture emerges if we focus not on individual citizens, but on the aggregate characteristics of geographic constituencies. Using biennial estimates of the economic, racial, and social policy liberalism of the average Democrat and Republican in each state over the past six decades, we demonstrate a surprisingly close correspondence between mass and elite trends. Specifically, we find that: (1) ideological divergence between Democrats and Republicans has widened dramatically within each domain, just as it has in Congress; (2) ideological variation across senators’ partisan subconstituencies is now explained almost completely by party rather than state, closely tracking trends in the Senate; and (3) economic, racial, and social liberalism have become highly correlated across partisan subconstituencies, just as they have across members of Congress. Overall, our findings contradict the reigning consensus that polarization in Congress has proceeded much more rapidly and extensively than polarization in the mass public.     

No Need to Watch: How the Effects of Partisan Media Can Spread via Interpersonal Discussions

To what extent do partisan media sources shape public opinion? On its face, it would appear that the impact of partisan media is limited, given that it attracts a relatively small audience. We argue, however, that its influence may extend beyond its direct audience via a two‐step communication flow. Specifically, those who watch and are impacted by partisan media outlets talk to and persuade others who did not watch. We present experimental results that demonstrate this process. We therefore show that previous studies may have significantly underestimated the effect of these outlets. We also illustrate that how the two‐step communication flow works is contingent upon the precise composition of the discussion group (e.g., is it consistent of all fellow partisans or a mix of partisans?). We conclude by highlighting what our results imply about the study of media, preference formation, and partisan polarization.     

Complex Contracting: Management Challenges and Solutions

Governments at all levels buy mission‐critical goods and services whose attributes and performance requirements are hard to define and produce. Many governments—and the public managers who lead them—lack experience and knowledge about how to contract for complex products. The contract management counsel provided to public managers is thin. Missing is a conceptual managerial framework to guide purchasing the complex products that are often so critical to public organizations' core missions. Drawing on perspectives from across the social sciences, the framework presented in this article provides guidance on how managers can harness the upsides of complex contracting while avoiding its pitfalls. The framework helps identify conditions that increase the likelihood of positive outcomes for the purchasing government and the vendor—the win‐win. To illustrate the framework, the article provides examples of successful and failed acquisitions for complex products such as transportation projects, social service systems, and information technology systems.     

Why do South-east Asian states choose to suppress opium? A cross-case comparison

Abstract

This paper compares the reasons given by three South-east Asian states (Laos, Thailand and Vietnam) for choosing to suppress opium production. While external pressure, often from the US or United Nations (UN)/League of Nations, is the most commonly identified reason in the literature, and was experienced in each case, it was not by itself sufficient to motivate states into action. All three cases were motivated by religious or ideological opposition to drug consumption or trade, rural development, state extension and concern for increasing domestic drug consumption. Apprehension about rising drug consumption often possessed racial or chauvinistic elements. The development of export commodities, environmental protection and national security were also identified in one or two cases. The paper concludes by hypothesising that economic and/or security considerations underlie all choices to suppress illicit drug crops.     

The non-governmental provision of search and rescue in the Mediterranean and the abdication of state responsibility

From January 2015 to December 2017, approximately 1.6 million migrants crossed the Mediterranean to reach Europe. The death toll was dramatic, with almost 15,000 drowning. In response to the void left by the ending of the Italian-led Mare Nostrum mission, several non-governmental organizations (NGOs) launched their own search and rescue (SAR) operations, rescuing over 110,000 migrants. In this article, we argue that states have the responsibility not only to coordinate, but also to directly provide adequate SAR operations in the Mediterranean, and that these responsibilities are presently being abdicated. Although much criticism of NGO maritime rescuing operations is misplaced, non-governmental SAR has notable limitations, and states are ultimately responsible for this shortfall.     

Radical Beliefs and Violent Actions Are Not Synonymous: How to Place the Key Disjuncture Between Attitudes and Behaviors at the Heart of Our Research into Political Violence

This article develops and elaborates on three core points. First, as with research into other social science themes, it is argued that it is necessary to apply the logic of correlation and causality to the study of political violence. Second, it highlights the critical disjuncture between attitudes and behaviors. Many or most individuals who support the use of political violence remain on the sidelines, including those who sympathize with insurgents in Afghanistan (reportedly 29 percent in 2011), and those supportive of “suicide attacks” in the Palestinian Territories (reportedly reaching 66 percent in 2005). Conversely, those responsible for such behaviors are not necessarily supportive of the ostensible political aims. Third, it is argued that the motives that drive these attitudes and behaviors are often (or, some would argue, always) distinct. While the former are motivated by collective grievances, there is substantial case study evidence that the latter are commonly driven by economic (e.g., payments for the emplacement of improvised explosive devices), security-based (i.e., coercion) and sociopsychological (e.g., adventure, status, and vengeance) incentives. Thus, it is necessary for the research community to treat attitudes and behaviors as two separate, albeit interrelated, lines of inquiry.
