The Analysis of Black Powder Substitutes Containing Ascorbic Acid by Ion Chromatography/Mass Spectrometry*†

Abstract: Black powder substitutes containing ascorbic acid are a group of low explosives that utilize ascorbic acid as the fuel. The analysis of these powders is complicated by the degradation of ascorbic acid which occurs rapidly in solution and may also occur as the powder ages. Aqueous extracts of both intact powders and postblast residues were analyzed by an existing ion chromatography/mass spectrometry (IC/MS) method used at the Bureau of Alcohol, Tobacco, Firearms and Explosives. Results have shown that while ascorbic acid itself is not detected in this method, its diagnostic degradation products (threonic acid, monohydrated diketogulonic acid, and oxalic acid) can be identified. In addition, anions from the inorganic oxidizers (perchlorate and nitrate) and combustion products such as chloride, chlorate, and nitrite, can be identified within the same experiment. While this IC/MS method shows promise, future modifications are necessary because of limitations in identifying threonate in postblast residues, as well as coeluting compounds observed in postblast residues.     

The Santa Clara County Greenbook Story: From Theory to Transformation

This article is an overview of the past 20 years, from a judicial perspective, of how a discreet selection of Greenbook recommendations were implemented in Santa Clara County, California. This historical overview shows that it is possible to take a guidebook written by national experts from many jurisdictions and tailor the intervention to a particular location with the assistance of local leadership. We applied a theoretical framework to government agency interventions and to the very real needs of families, and that process resulted in a profound transformation of practice.     

Ridge Width Correlations between Inked Prints and Powdered Latent Fingerprints

A methodology to estimate the time of latent fingerprint deposition would be of great value to law enforcement and courts. It has been observed that ridge topography changes as latent prints age, including the widths of ridges that could be measured as a function of time. Crime suspects are commonly identified using fingerprint databases that contain reference inked tenprints (flat and rolled impressions). These can be of interest in aging studies as they provide baseline information relating to the original (nonaged) ridges’ widths. In practice, the age of latent fingerprints could be estimated following a comparison process between the evidentiary aged print and the corresponding reference inked print. The present article explores possible correlations between inked and fresh latent fingerprints deposited on different substrates and visualized with TiO₂. The results indicate that the ridge width of flat inked prints is most similar to fresh latent fingerprints_, and these should be used as the comparison standard for future aging studies.     

Examining Predictors of Parole Release in a Rural Female Jail Population

Parole has long been a linchpin of correctional practices but few studies have examined discretionary parole release in a female population. The current study examines factors, both static risk and dynamic needs, that influence parole decision making in a rural female jail population. The researchers collected data on parole releases from a rural county jail over a 3-year period beginning in 2012 (N?=?138). Offenders obtained a recommendation for parole release from a reentry assessment team that met at the jail each month to evaluate cases for parole eligibility. Logistic regression was used to explain variance in the factors considered by the reentry assessment team and it was evident that both static risk factors and dynamic needs play a role in discretionary parole release. We also examined obstacles or challenges that female offenders face when paroling to a rural location. Several policy recommendation related to the study are addressed.     

Sharia Courts and Muslim Personal Law in India: Intersecting Legal Regimes

In July 2005, a Delhi lawyer filed suit with the Supreme Court of India seeking to ban “sharia courts” (dar ul qazas) and Islamic legal opinions, arguing that they constitute a “parallel judicial system” that undermines the state's legal institutions. The Supreme Court decided in 2014 that dar ul qazas are not parallel but appropriate alternative forums. In this article, I analyze several divorce cases in Delhi and Patna dar ul qazas to show that, rather than being alternative or parallel, dar ul qazas intersect with state courts. Attending to this intersection, I argue, has implications for how we understand legal pluralism, secularism, and the relation between them. Specifically, I argue that because of how cases travel between dar ul qazas and state courts, dar ul qazas help to consolidate the oppositions between religious and secular law, kin relations, and rights upon which secularism relies.     

Herceptin, Pharmac and the New Zealand District Health Boards: keeping abreast of the Code of Health and Disability Services Consumers' Rights?

In an era of resource limitations, the problem of matching public expectations with health care provision will always be difficult. In New Zealand there has been recent debate surrounding the potential funding by the Pharmaceutical Management Agency (PHARMAC) of an expensive chemotherapy agent called Herceptin (trastuzumab). Taking the proposed funding options in turn, this article looks at the obligations PHARMAC and the New Zealand District Health Boards might then be subject to with respect to the legislation and the Code of Health and Disability Services Consumers' Rights, and the impact this might have on a health system already subject to resource constraints.
