Effects of Cyanoacrylate Fuming,Time After Recovery,and Location of Biological Material on the Recovery and Analysis of DNA from Post‐Blast Pipe Bomb Fragments*

Abstract: This study investigated the effects of time, cyanoacrylate fuming, and location of the biological material on DNA analysis of post‐blast pipe bomb fragments. Multiple aliquots of a cell suspension (prepared by soaking buccal swabs in water) were deposited on components of the devices prior to assembly. The pipe bombs were then deflagrated and the fragments recovered. Fragments from half of the devices were cyanoacrylate fumed. The cell spots on the fragments were swabbed and polymerase chain reaction/short tandem repeat analysis was performed 1 week and 3 months after deflagration. A significant decrease in the amount of DNA recovered was observed between samples collected and analyzed within 1 week compared with the samples collected and analyzed 3 months after deflagration. Cyanoacrylate fuming did not have a measurable effect on the success of the DNA analysis at either time point. Greater quantities of DNA were recovered from the pipe nipples than the end caps. Undeflagrated controls showed that the majority (>95%) of the DNA deposited on the devices was not recovered at a week or 3 months.     

The Utility of Expanded Conclusion Scales During Latent Print Examinations

During fingerprint comparisons, a latent print examiner visually compares two impressions to determine whether or not they originated from the same source. They consider the amount of perceived detail in agreement or disagreement and accumulate evidence toward same source and different sources propositions. This evidence is then mapped to one of three conclusions: Identification, Inconclusive, or Exclusion. A limitation of this 3-conclusion scale is it can lose information when translating the conclusion from the internal strength-of-evidence value to one of only three possible conclusions. An alternative scale with two additional values, support for different sources and support for common sources, has been proposed by the Friction Ridge Subcommittee of OSAC. The expanded scale could lead to more investigative leads but could produce complex trade-offs in both correct and erroneous identifications. The aim of the present study was to determine the consequences of a shift to expanded conclusion scales in latent print comparisons. Latent print examiners each completed 60 comparisons using one of the two scales, and the resulting data were modeled using signal detection theory to measure whether the expanded scale changed the threshold for an “Identification” conclusion. When using the expanded scale, examiners became more risk-averse when making “Identification” decisions and tended to transition both the weaker Identification and stronger Inconclusive responses to the “Support for Common Source” statement. The results demonstrate the utility of an expanded conclusion scale and also provide guidance for the adoption of these or similar scales.     

Attention as a Valuable Resource

Keeping up with the news and monitoring public affairs are typically considered civic obligations. Yet there is a great deal of competition for people’s limited attention. Some studies explore when people tune in to the news and what sorts of public affairs content attract our time, but these topics warrant more research. Scholars concerned with the news media’s political role must better understand what leads people to the news in the first place. The practical import of this work is pronounced in an era where news organizations struggle to make ends meet. The purpose of this essay is to categorize what we know about what motivates people to tune in to news and then to propose a research agenda for analyzing attention to public affairs content.     

The Implications of Endemic Corruption for State Legitimacy in Developing Nations: an Empirical Exploration of the Nigerian Case

There is an extensive literature on the ramifications of corruption for economic growth, as well as for democracy. Largely unexplored, however, is how corruption works to lessen government legitimacy and empower violent anti-state movements. In this article, the perception of corruption in Nigeria is considered. Noting that Nigeria must suppress the violent extremist group Boko Haram in order to continue to govern the nation, the connections between Nigerian perceptions of corruption and support for the movement are treated. Until this research, however, there existed no empirical evaluation of this relationship. Using analysis of a survey of over 10,000 Nigerians accomplished in 2012 and 2013, we show that issues of state illegitimacy and endemic corruption have contributed to Nigeria’s present security crisis by fomenting support for non-state violent actors.     

Gender Justice or Gendered Justice? Female Defendants in International Criminal Tribunals

Recent scholarship has given increasing attention to studying women’s involvement in conflict and mass violence. However, there is comparatively less discussion of the experiences of women as actors and perpetrators in conflict, and limited discussion of women as defendants in international criminal tribunals. This article explores this under-researched area. By analysing legal materials from the cases of six female defendants, this article investigates the extent to which legal discourses are shaped by stereotypes regarding femininity, conflict and peace. It identifies three gender narratives—mothers, monsters and wives—used in relation to female defendants, which highlight the incompatibility of femininity with violence, and deny women’s agency in political and military contexts. Thus, this article concludes that female defendants in international criminal tribunals are viewed through gendered lenses, and discussed in accordance with gendered themes. This gendered justice is problematic, as it reinforces patriarchal gender stereotypes, and may hinder attempts to facilitate gender justice.     

Social Media Social Comparison of Ability (but not Opinion) Predicts Lower Identity Clarity: Identity Processing Style as a Mediator

Social comparison on social media has received increasing attention, but most research has focused on one type of social comparison and its psycho-emotional implications. Little is known about how different types of social comparison influence youth’s identity development. Drawing on the theories of identity processing styles and social comparison, we examined how two different forms of social comparison on social media related to three identity processing styles, which in turn predicted youth’s global self-esteem and identity clarity. We surveyed 219 college freshmen (M_age?=?18.29; 74% female) once in the Fall and once in the Spring. Social comparison of ability on social media was related to concurrent diffuse-avoidant identity processing style, which predicted lower identity clarity months later. In contrast, social comparison of opinion on social media did not influence college freshmen’s global self-esteem and identity clarity through identity processing styles. The findings clarified the implications of online social comparison for youth’s identity development.     

Religiosity and Rebellion in Nigeria: Considering Boko Haram in the Radical Tradition

Testing social movement theory positing that radical organizations are ideologically driven at their core, but are supported by civilians who are driven by social factors, this research interrogates the disparity between radical group ideology and supporter belief set in the context of present-day Nigeria. Content analysis of randomly selected Boko Haram publications establishes the high, and increasing, levels of religiosity exhibited by the violent social movement itself. In contrast, a large-N survey of Nigerians conducted in 2012 and 2013 shows that high levels of religiosity do not significantly predict willingness to justify violence, commitment to non-state violent actors, or positive attitude toward Boko Haram among Nigerians as a whole, but rather the opposite. Given these findings, Boko Haram may be better understood within the tradition of radical extremist movements across the ideological spectrum, even while it frames its struggle as that of a distinctly religious movement.     

Strategic change,leadership and accounting: A triptych of organizational reform

Strategic change in public sector organizations has been well documented. This article suggests that public management research would benefit from a greater appreciation of how calculative practices are deeply imbricated with, and constitutive of, organizational life. In turn, the article argues that the field of interdisciplinary accounting has much to learn from public administration, especially in terms of leadership. The overarching argument is that understanding strategic change in public organizations can be enhanced by bringing together insights from the academic fields of public administration and interdisciplinary accounting. In this respect, organizational reform can be understood as a triptych, involving strategic change, leadership and accounting practices. We illustrate this thesis through a case study of strategic change in the world's largest public service broadcaster—the British Broadcasting Corporation (BBC). It is shown how, during the tenure of one organizational leader—John Birt—accounting became pivotal to his leadership.     

Diversionary cheap talk: economic conditions and US foreign policy rhetoric, 1945-2010

ABSTRACT

This study explains how the economy affects the foreign policy rhetoric used by American presidents. When economic conditions deteriorate, presidents criticize foreign nations to boost their approval ratings. Presidents use this “diversionary cheap talk” in response to the misery index of unemployment plus inflation, which poses a unique threat to their popularity. They target historical rivals, which make intergroup distinctions most salient. Diversionary cheap talk is most influential for and most frequently used by Democratic presidents, whose non-core constituents prefer hawkish foreign policy but already expect it from Republican presidents. I test the observable implications of the theory with the American Diplomacy Dataset, an original record of 50,000 American foreign policy events between 1851 and 2010 drawn from a corpus of 1.3 million New York Times articles.     

Whatever happened to the new public administration?

The “New Public Administration” advocated the infusion of value preferences into areas of administrative practice. In assessing the historical legacy and contemporary applicability of the movement, the authors examine its objectives in view of changing political and administrative commitments. The article criticizes the extent to which institutionalizing administrative values gives way to “value-shifting” when electoral moods change.
