Thermal degradation analysis of amino acids in fingerprint residue by pyrolysis GC-MS to develop new latent fingerprint developing reagents

Conventional development of latent fingerprints is compromised when the prints are decomposed by extreme temperatures, such as those encountered when a weapon cartridge is fired, an improvised explosive device is detonated, and/or in arson cases. Understanding how these extreme temperatures alter the chemical and physical properties of latent fingerprint residue could aid in the discovery of a reagent that could effectively develop these decomposed fingerprints. To mimic scenarios where fingerprints may be exposed to high heat conditions, standards of the five most abundant amino acids in fingerprint residue as well as extracted fingerprint residue were pyrolized under controlled conditions. Compounds identified as pyrolytic decomposition products were 3,6-dimethylpiperazine-2,5-dione (from alanine), maleimide, and 2,5-furandione (from aspartic acid). The pyrograms and selected ion traces show these products to hold promise as indicators of decomposed fingerprint residues and, therefore, may serve as good candidate substrates for a developing reagent.     

UNICEF, syphilis and the state: negotiating female citizenship in the post-Second World War world

Few charitable organizations have achieved the status of global recognition enjoyed by UNICEF, the United Nations Children's Fund, which embodies the international effort to provide for needy children the world over. Created because of its synchronicity with the United Nations' stated purpose—to maintain peace in the world—UNICEF launched its operations in 1946. Its founding, early operations and eventual restructuring reveal a great deal about concurrent political and economic events, but also provide keen insight into international ideas about who qualified for full citizenship in the post-war world. The consequences of UNICEF's policies, procedures and practices posed challenges to notions of citizenship for both women and children. It challenged citizenship not by questioning sex-specific gender roles, but by judiciously adhering to the United Nations' promise to create equality for men and women alike. UNICEF found itself in the unique position to be able to globalize definitions of what constituted full citizenship in any nation, due to its rapid expansion throughout the world. Through its programs, especially those related to health care, it not only challenged these roles in the West, but began over several decades to complicate the definition of citizenship as it became a forceful presence in Asia and Africa throughout the 1970s.     

Public Attitudes Toward Immigration Policy Across the Legal/Illegal Divide: The Role of Categorical and Attribute-Based Decision-Making

Scholars debate the relative strength of economic and ‘socio-psychological’ sources of anti-immigrant sentiment. However, the literature often fails to distinguish legal from illegal immigration and therefore overlooks a major instance in which this debate is moot. To address this issue, we develop a theory that recognizes two different modes of evaluating immigrants: “attribute-based” judgment, in which respondents weigh immigrants’ desirability based on individual characteristics—human capital, race, language ability, and so on—and “categorical” judgment, which disregards these altogether. Categorical judgments arise when a policy issue triggers blanket considerations of justice or principle that obviate considerations about putative beneficiaries’ individual merits, instead evoking overriding beliefs about the desirability of the policy as a whole or casting the entire category as uniformly deserving or undeserving. We use experimental evidence from two national surveys to show that the principal distinction between attitudes toward legal and illegal immigration is not in the relative weight of immigrants’ attributes but the much greater prevalence of categorical assessments of illegal immigration policy, much of it rooted in rigid moralistic convictions about the importance of strict adherence to rules and laws.     

Welfare Reform, Mississippi Style: Temporary Assistance for Needy Families and the Search for Accountability

Through an examination of the implementation of the 1996 Personal Responsibility and Work Opportunity Act in the state of Mississippi, we explore the adequacy of traditional two-actor principal-agent theory. Using this as our lens, we suggest that the choices made by Mississippi in the area of welfare reform to privatize much of the work and to add several layers to the existing principal-agent relationship substantially reduced accountability and the effectiveness of the monitoring systems. We conclude that not only is traditional principal-agent theory an insufficient tool for understanding the complex interrelationship between democratic actors in this particular case, the decisions of the state of Mississippi to complicate the principal-actor relationship through privatization also undermined the reform effort itself in ways that may have general implications for other like-minded efforts in other policy areas.
