A New Method for the Removal and Analysis of Small Particles Adhering to Carpet Fiber Surfaces,,

Fibers are a commonly encountered evidence type and fiber comparisons are routinely conducted. When the characteristics of questioned and known fibers correspond, the probative value is limited because the characteristics compared are determined by their manufacture. It would be valuable to test the hypothesis that questioned fibers originated from a specific carpet. One means of testing this is to analyze fine particles on the fibers. A procedure was developed for removing adhering particles from fibers and preparing them for scanning electron microscopy/ energy dispersive X‐ray spectrometry (SEM/EDS) analysis. The efficacy of several fluids (acetone, ethanol, hexanes, aqueous ethanol, aqueous sodium hexametaphosphate) and agitation methods (sonication and vortexing) for removing particles from fibers was evaluated. The most effective method evaluated was sonication in ethanol for 10 min. The recovered particles were filtered onto a polycarbonate filter and analyzed by automated SEM/EDS analysis to generate data on the particle assemblage. This method makes possible future research to test the within‐item and between‐item variability of particle assemblages on fibers.     

Raman Spectroscopy as a Simple,Rapid, Nondestructive Screening Test for Methamphetamine in Clandestine Laboratory Liquids

Raman spectroscopy has found increased use in the forensic controlled substances laboratory in recent years due to its rapid and nondestructive analysis capabilities. Here, Raman spectroscopy as a screening test for methamphetamine in clandestine laboratory liquid samples is discussed as a way to improve the efficiency of a laboratory by identifying the most probative samples for further workup among multiple samples submitted for analysis. Solutions of methamphetamine in ethanol, diethyl ether, and Coleman fuel were prepared in concentrations ranging from 0.5% to 10% w/v, and Raman spectra of each were collected. A concentration‐dependant Raman peak was observed at 1003 per cm in each solution in 4% w/v and greater solutions. Case samples were analyzed and also found to reliably contain this diagnostic peak when methamphetamine was present. The use of this diagnostic indicator can save the forensic controlled substances laboratory time and materials when analyzing clandestine laboratory liquid submissions.     

Ultrafast Amplification of DNA on Plastic Microdevices for Forensic Short Tandem Repeat Analysis

The majority of microfluidic devices used as a platform for low‐cost, rapid DNA analysis are glass devices; however, microchip fabrication in glass is costly and laborious, enhancing the interest in polymeric substrates, such as poly (methyl methacrylate) (PMMA), as an inexpensive alternative. Here, we report amplification in PMMA polymerase chain reaction (PCR) microchips providing full short tandem repeat profiles (16 of 16 loci) in 30–40 min, with peak height ratios and stutter percentages that meet literature threshold requirements. In addition, partial profiles (15 of 16 loci) were generated using an ultrafast PCR method in 17.1 min, representing a ~10‐fold reduction in reaction time as compared to current amplification methods. Finally, a multichamber device was demonstrated to simultaneously amplify one positive, one negative, and five individual samples in 39 min. Although there were instances of loci dropout, this device represents a first step toward a microfluidic system capable of amplifying more than one sample simultaneously.     

The Instruments of Abolition, or Why Retributivism is the Only Real Justification of Punishment

Victor Tadros’ The Ends of Harm is the most recent systematic attempt to defend the good old utilitarian justification of punishment. The attempt fails for a variety of reasons, which are here explored. First, the attempt presupposes an implausible account of human’s psychology. Second, the attempt confuses an attack on retributivism with an attack on certain criminal justice systems. Finally, Tadros admits that his justification of punishment is best seen as a mere step along the road to full-blown abolitionism – and so he unwittingly admits the extraordinarily thin sense in which he could be said to be really attempting to justify punishment.     

How American Commercial Bail Developed Differently from Other Common Law Countries

Outside the United States those countries sharing the common law tradition are pervasively hostile to commercialization of the bail process, whereas in the United States it is the typical approach. In some jurisdictions payment for bail is a crime; in others it is simply obstructed by various civil legal disabilities. How the American branch of the common law heritage came to deviate so strikingly from the rest on the matter of commercial bail is the topic of this article.

Beginning in the second half of the nineteenth century, courts principally in Ireland, England, and India began to act against payment to bail sureties on the concept that any indemnification of them—even partial—undermined their reliability. Irish courts took the approach that indemnified potential sureties were unreliable and should be rejected by courts. Where all potential sureties were indemnified, bail should be denied. In England courts declared agreements to indemnify sureties illegal contracts contrary to public policy, which would not be enforced by courts. While India took up the refinement of this position, England went on to declare agreements to pay bail sureties to be criminal conspiracies.

Meanwhile in the United States a circumscribed version of the position that indemnification contracts were against public policy—and therefore illegal and unenforcible—actually gained acceptance between 1870 and 1912. In 1912, however, Justice Holmes in Leary v. U.S. renounced the common law concept of bail sureties in favor of an “impersonal and wholly pecuniary” view. This terminated the anti-indemnification movement. Courts soon noted the detrimental effects of commercialism on bail.     

Hostage negotiation in Costa Rica

This article compares legal and procedural constraints that operate on United States and Costa Rican hostage negotiations. In an effort to better understand the Costa Rican police system, comparisons are drawn between United States law enforcement agencies, United States military services and the Costa Rican police system. The introductory material lays the foundation for a discussion of hostage negotiation as it is practiced in Costa Rica prior to and after hostage negotiation training.     

Generational Transmission of Collective Memory about Tiananmen in Hong Kong: how young rally participants learn about and understand 4 June

This article addresses the problem of generational transmission of collective memory in Hong Kong about the 1989 Tiananmen Square incident. It focuses on the young participants in the annual 4 June commemoration rallies and examines the process of mnemonic socialization that brought them into the community of 4 June commemoration. Drawing upon a rally onsite survey and in-depth interviews, this study found that many young people went through a dynamic process of gradual discovery in which various social institutions—school, family and media—played complementary roles. Their understanding of Tiananmen tended to be simplified and essentialized. Yet the loss of details through essentialization has arguably allowed them to uphold a clear-cut moral judgment regarding the event and dismiss certain memory-blurring discourses straightforwardly.     

Repositioning American Public Administration? Citizen Estrangement,Administrative Reform,and the Disarticulated State

Levels of citizen estrangement from government in the United States have risen rather consistently since the late 1960s and have reached all‐time highs in recent years. Evidence is accumulating in political science research to suggest that public administrative theory may have contributed to this trend since the Progressive Era in the early 1900s. The authors develop this thesis by arguing that administrative theory in the United States has persistently portrayed public managers as “bridge builders” who link an expertise‐challenged citizenry to government in ways that emphasize bureaucratic over democratic administration. Moreover, despite claims of yet another “new” paradigmatic shift for the field, collaborative governance scholarship to date exhibits similar tendencies. To support this argument, the authors assess the common citizen‐marginalizing tendencies of three sets of administrative reforms in American public administration: the progressive, associationalist, and polycentric heritages. They offer counterarguments to this thesis and call for critical self‐reflection by the field and a more empirically robust research agenda on this topic.     

The illusory leader: natural resources, taxation and accountability

This paper proposes and tests a mechanism through which natural resources can affect democracy. I posit that, in the presence of high natural resource rents, leaders lower the burden of taxation on citizens in order to reduce the demand for democratic accountability. The theory is corroborated using micro-level data from public opinion surveys across 15 sub-Saharan countries, in addition to country-level data on natural resource rents. Results are robust to a range of alternative specifications. A supplementary analysis reveals that, consistent with the two-period model proposed, the effects are more acute closer to national elections.
