Compositional analysis for identification of arson accelerants by electron ionization Fourier transform ion cyclotron resonance high-resolution mass spectrometry

Elemental compositions of each of 100 to 500 different constituents (i.e., every peak in a mass-to-charge ratio range, 50 < m/z < 300) of lighter fluid, kerosene, turpatine, gasoline, diesel fuel, and two brands of mineral spirits (and their weathered analogs) make possible direct identification of each accelerant in a experimental fire, based on electron ionization 6.0 Tesla Fourier transform ion cyclotron resonance (EI FT-ICR) ultrahigh resolution mass spectrometry. Septum injection of as little as 500 nL of accelerant into an all-glass heated inlet system yields definitive elemental compositions (molecular formulas) based on accurate (< +/-1 ppm average error) mass measurement alone. Extraction and EI FT-ICR mass analysis of fire debris from a controlled burn of a couch with simple (lighter fluid) and complex (turpatine) ignitable liquid yielded dozens of elemental compositions serving as a unique "fingerprint" for each petroleum product, despite the presence of up to 249 additional extracted matrix and pyrolysis components. Forty-five of 56 lighter fluid constituents and 126 of 133 turpatine constituents (not counting 13C-containing species) were identified in the debris from a fire staged for each respective accelerant.     

Cumulating the Intellectual Gold of Case Study Research

Two criticisms of public administration research have been leveled. First, knowledge in the field is not being cumulated. Second, the research has low quality. A preference for case studies as a form of scientific inquiry is behind both criticisms. The authors propose a solution to the first problem by showing how meta-analysis can be used to cumulate knowledge using case study evidence. Viewed cumulatively, case studies comprise an intellectual goldmine awaiting discovery. The authors challenge the second criticism, proposing that quality judgments should be based on the important principle of knowledge cumulation, which acknowledges the value of all research methods.     

Depression as a Moderator of Sociocultural Influences on Eating Disorder Symptoms in Adolescent Females and Males

This study aimed to explore the role of depression as a moderator of sociocultural influences on eating disorder symptoms. A sample of 509 adolescents (56% female) completed self-report questionnaires assessing depression, body dissatisfaction, drive for thinness, bulimic symptoms and sociocultural influences on appearance from family, peers and the media. Both girls and boys displaying high levels of depressive symptoms perceived stronger media and peer influences on appearance. Among girls, eating disorder symptoms were directly affected by sociocultural influences, in particular media influences, as well as by depression. However, depression played only a limited role as a moderator of these relationships. Among boys, sociocultural influences and depression revealed fewer direct effects on eating disorder symptoms. However, depression had a greater moderating effect on these relationships. Future research into the role of depression may increase the understanding of gender differences in body dissatisfaction, drive for thinness and bulimic symptoms.     

Contrasts in Development in Bihar: A Tale of Two Villages

Abstract

The article investigates the economic and social changes that have occurred over the last 30 years in two villages in Bihar, one of the poorest states in India. The two villages are on different development paths: one based on agricultural diversification and local non-agricultural employment, the other dependent on migration to distant labour markets. They therefore connect with India’s overall growth in different ways. Neither development model delivers clearly superior outcomes in terms of incomes, nor are they exhausted, but the long-term sustainability of a migration-led model remains debatable.     

Melting Down and Scaling Up: Stabilizing Climate Change by Promoting Private Sector Technology Development

This paper will examine the role the private sector plays in researching, developing, and deploying technology that has the potential to deter or decrease the impacts of global warming. It will explore the degree to which the private sector can have an impact on global warming by focusing on four specific technologies: aircraft engines, wind turbines, solar energy, and clean coal technologies. We will compare the environmental impact of these technologies with the business case for pursuing each, specifically related to profitability and market maturity. We conclude that the business case alone is not sufficiently compelling to stimulate meaningful industry investment in these areas. Consequently, specific government involvement is needed for CO₂ reduction. This analysis will shed light on the role that government must play in order to more effectively engage potential private sector players in the global warming challenge.     

The uses of models in legislative planning

Previous research on United States public employee strikes has considered the occurrence and breadth of strikes, but seldom duration, as dimensions of the strike which merit examination. This study considers a much neglected dimension of strikes, duration, which is particularly important to public administrators and unions who become actively involved with resolving such disputes. Factors which theoretically were expected to be associated with the duration of public employee strikes--the economic expectations of the striking workers, various characteristics of the bargaining environment, and the fiscal condition of the jurisdiction taking the strike-—were identified and considered. Results indicated that one factor in particular, the fiscal constraints of the jurisdiction taking the strike, was significantly associated with longer strikes, indicating that public employee unions may not necessarily be deterred from engaging in protracted strikes because of a precarious fiscal climate.     

The Fiction of Development: Literary Representation as a Source of Authoritative Knowledge

This article introduces and explores issues regarding the question of what constitute valid forms of development knowledge, focusing in particular on the relationship between fictional writing on development and more formal academic and policy-oriented representations of development issues. We challenge certain conventional notions about the nature of knowledge, narrative authority and representational form, and explore these by comparing and contrasting selected works of recent literary fiction that touch on development issues with academic and policy-related representations of the development process, thereby demonstrating the value of taking literary perspectives on development seriously. We find that not only are certain works of fiction ‘better’ than academic or policy research in representing central issues relating to development but they also frequently reach a wider audience and are therefore more influential. Moreover, the line between fact and fiction is a very fine one, and there can be significant advantages to fictional writing over non-fiction. The article also provides an Appendix of relevant works of fiction that we hope academics and practitioners will find both useful and enjoyable.     

State TANF Spending: Predictors of State Tax Effort to Support Welfare Reform

State spending on Temporary Assistance to Needy Families (TANF) greatly varies. Combined federal and state spending by the states per TANF family or recipient reflects the historic level of state generosity for Aid to Families with Dependent Children (AFDC), the failure of the federal government to set any minimum spending standard for the states, and the failure of the federal government to adjust federal grants for huge changes in state TANF caseloads. Our multivariate analysis shows that state spending for TANF is greatly influenced by the percentage of the state population that is black, the percentage of the state population that is on TANF (especially if a significant percentage of the rolls consist of black recipients), and the economic conditions within the state. Some states spend as much as their economies will allow, while other states spend far below capacity. Despite the very different goals of TANF, state spending is still heavily influenced by their historic approach to AFDC.
