The effect of ionizing gamma radiation on natural and synthetic fibers and its implications for the forensic examination of fiber evidence

Circumstances of criminal activities involving radioactive materials may mean fiber evidence recovered from a crime scene could have been exposed to materials emitting ionizing radiation. The consequences of radiation exposed fibers on the result of the forensic analysis and interpretation is explored. The effect of exposure to 1-1000 kGy radiation doses in natural and synthetic fibers was noticeable using comparative forensic examination methods, such as optical microscopy, microspectrophotometry, and thin-layer chromatography. Fourier transform infrared spectroscopy analysis showed no signs of radiation-induced chemical changes in any of the fiber structures. The outcome of the comparative methods highlights the risk of "false negatives" associated in comparing colors of recovered fibers that may have been exposed to unknown radiation doses. Consideration of such results supports the requirement to know the context, including the environmental conditions, as much as possible before undertaking a forensic fiber examination.     

DO NEIGHBORHOODS GENERATE FEAR OF CRIME? AN EMPIRICAL TEST USING THE BRITISH CRIME SURVEY*

For a long time, criminologists have contended that neighborhoods are important determinants of how individuals perceive their risk of criminal victimization. Yet, despite the theoretical importance and policy relevance of these claims, the empirical evidence base is surprisingly thin and inconsistent. Drawing on data from a national probability sample of individuals, linked to independent measures of neighborhood demographic characteristics, visual signs of physical disorder, and reported crime, we test four hypotheses about the mechanisms through which neighborhoods influence fear of crime. Our large sample size, analytical approach, and the independence of our empirical measures enable us to overcome some of the limitations that have hampered much previous research into this question. We find that neighborhood structural characteristics, visual signs of disorder, and recorded crime all have direct and independent effects on individual‐level fear of crime. Additionally, we demonstrate that individual differences in fear of crime are strongly moderated by neighborhood socioeconomic characteristics; between‐group differences in expressed fear of crime are both exacerbated and ameliorated by the characteristics of the areas in which people live.     

Support Structures and Constitutional Change: Teles,Southworth, and the Conservative Legal Movement

This essay reviews two recent works in political science on the American conservative legal movement: Steven M. Teles's The Rise of the Conservative Legal Movement: The Battle for Control of the Law (2008) and Ann Southworth's Lawyers of the Right: Professionalizing the Conservative Coalition (2008). It examines these books in the context of a larger debate over the variables that best explain constitutional change in general and the recent “conservative counterrevolution” in Supreme Court jurisprudence in particular. It shows how these studies build on the scholarship of Charles Epp, who argued in The Rights Revolution (1998) that serious constitutional change requires not only the right cast of characters on the court, but also a strong “support structure” in the legal profession and civil society. Finally, it draws on the author's own research on the Federalist Society for Law and Public Policy to illustrate some important avenues for further inquiry.     

Waste in the Sewer: The Collapse of Accountability and Transparency in Public Finance in Jefferson County,Alabama

Following failed auctions for sewer debt in April 2008, major bond rating companies downgraded Jefferson County, Alabama’s bond rating to D (default) triggering massive mandatory payments by the county to its creditors. At the time of writing, the county teeters on the brink of actual default and bankruptcy, unable to pay service on its $3.3 billion sewer debt portfolio. If the county defaults, it will be the largest municipal bankruptcy in United States history, eclipsing Orange County, California’s 1994 default. The intriguingly complex tale of the Jefferson County debt crisis is recounted here by identifying and examining failures of transparency and accountability by local bureaucratic and political actors, private financial institutions, as well as the larger regulatory framework governing public finance. Enhanced regulation of local government and the financial sector plus greater local government capacity to close accountability gaps and thus prevent future crises of similar scale in this or other jurisdictions are recommended.     

PBB in American Local Governments: It's More than a Management Tool

Despite academic findings that performance information seldom is used in appropriations decisions, many professional organizations and governments continue to press for integrating performance information into local public management, planning, and budgeting processes. Is it possible to reconcile such inconsistencies? Looking beyond the executive–legislative relationship and departmental appropriations, the author examines the budget implications of applying performance information at the subdepartmental program level. Case analysis of Indianapolis’s IndyStat initiative underscores that performance measurement application is positively related to intradepartmental program budget changes. Hence, performance‐based budgeting (PBB) can improve local budgeting despite severe political constraints. Still, successful use of PBB requires strong executive leadership, and its effects remain less visible at the departmental level or within the wider political arena of legislative bargaining. The author concludes by recommending some rethinking of the current analytical focus of PBB both in future research as well as recommended practice.     

Polarization and Issue Consistency Over Time

The polarization of the political and social environment over the past four decades has provided citizens with clearer cues about how their core political predispositions (e.g., group interests, core values, and party identification) relate to their issue opinions. A robust and ongoing scholarly debate has involved the different ways in which the more polarized environment affects mass opinion. Using heteroskedastic regression, this paper examines the effect of the increasingly polarized environment on the variability of citizens’ policy opinions. We find that citizens today base their policy preferences more closely upon their core political predispositions than in the past. In addition, the predicted error variances also allow us to directly compare two types of mass polarization—issue distance versus issue consistency—to determine the independent effects each has on changes in the distribution of mass opinion.     

Disparities in the Spending Needs of Highland Municipalities

A certain rough consensus holds that highland municipalities have higher spending needs than others, because of the particularly adverse conditions in which they provide essential public services. However, there is no empirical evidence to support this assertion. This study examines whether any relevant differences actually exist in the spending policies of highland and lowland municipalities. To this end, we make logarithmic estimations of per capita municipal spending in order to determine whether the indicators selected, which are based on local government powers, adequately reflect spending needs. Our results point to the special circumstances of highland districts as a key explanatory factor for higher municipal spending, along with demographic factors, locational population patterns, economic activity, subsidies, and local fiscal capacity.     

The Durability of EU Civil Service Policy in Central and Eastern Europe after Accession

This article examines the post‐accession durability of EU civil service policy in Central and Eastern Europe (CEECs). Civil service professionalization was a condition for EU membership but the European Commission has no particular sanctions available if CEECs reverse pre‐accession reforms after gaining membership. Comparing eight CEECs that joined the EU in 2004, the article finds that post‐accession civil service developments are characterized by great diversity. The three Baltic States continued civil service reforms, while Slovakia, the Czech Republic, Poland, and Slovenia are classified as cases of post‐accession reform reversal. The post‐accession pathway of Hungary is identified as a case of reform reorientation. The diversity in post‐accession pathways was almost exclusively the result of domestic political constellations, in particular, patterns of government alternation after accession. There were hardly any factors that could have locked in the level of professionalization that had been reached at the time of accession.     

Does more federal environmental funding increase or decrease states' efforts?

We examine the flow of federal grants‐in‐aid from the U.S. Environmental Protection Agency (EPA) to the states. We simultaneously model two dependent variables (the flow of EPA funds, and state environmental and natural resource budgets) to identify the independent roles of state political institutions, political preferences, economic and demographic characteristics, and the task environment. Our central focus, though, is on the relationship between grants and state spending after taking into account those direct effects. We examine the evidence for positive association (a flypaper effect) and negative association (crowding out). We show the different roles for political institutions, political preferences, demographic and economic characteristics, and the task environment in each spending context. Most importantly, we find evidence for a flypaper effect between federal funds and state spending: Federal spending and state spending are positively correlated after accounting for the contribution of the unique factors. © 2010 by the Association for Public Policy Analysis and Management.
