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.     

A Disabled Market: Free Movement of Goods and Services in the EU and Disability Accessibility

Individuals with a disability who wish to use goods and services can have a variety of specific needs, ranging from accessible written information to standard products and services which have disability accessibility features built into them. In light thereof, this article focuses on the impact which Community law has had, and could potentially have, on ensuring an EU‐wide market in products and services which are accessible to consumers with a disability. The article examines the (possible) impact of a variety of provisions, including the rules relating to the free movement of goods and services (Articles 28 and 49 EC, respectively), the internal market (Articles 94 and 95 EC), non‐discrimination (Article 13 EC), EU citizenship provisions, and the work of the European standardisation bodies such as CEN. The central question throughout the article is does EC law allow for, or discourage, the establishment of mandatory disability accessibility standards at the national or EU level, and have the provisions been used to permit or establish such standards to date?     

Effects of victim gender,victim sexual orientation,victim response and respondent gender on judgements of blame in a hypothetical adolescent rape

Objectives. Few studies have examined the judgements made towards adolescent rape victims, and none have investigated attributions towards gay male or lesbian adolescents. The current study examined the effects victim gender, victim sexual orientation, victim response, and respondent gender, on attributions of blame in the depicted rape of a 15‐year old adolescent. Methods. A total of 164 respondents read details of this assault before completing 15 attribution judgments. Results. Respondents were expected to attribute more blame to a victim who was male, gay, and who failed to resist the perpetrator. Male respondents were also expected to be more blaming of the victim than females. Overall these hypotheses were supported. Conclusion. Results are discussed in relation to the role gender stereotypes and homophobia play within attributions blame in sexual assault cases. Specifically, it seems male adolescent rape victims are subjected to the same negative stereotypes as male adult victims. Implications and ideas for future research are considered.     

SUPPORTING FAMILY STRENGTH: THE USE OF TRANSFORMATIVE MEDIATION IN A PINS MEDIATION CLINIC

This article describes, and explains the rationales for, the establishment of an innovative program in which a law school and two social services agencies are collaborating in a mediation clinic that uses the transformative model of mediation to serve clients in cases that seem ideally suited to benefit from this approach to practice—so-called "PINS" (persons in need of supervision) cases involving conflict within families, between parents and their adolescent children. The article first describes the evolution of the PINS system and the changing views of its purpose, especially in New York State. It then offers a brief introduction to the unique features of the transformative approach to mediation and explains why that approach in particular is likely to mesh with current understandings of the needs of the families involved in these cases. Finally, the article describes the innovative "Family Solutions Program" and how it uses transformative mediation to help these families and suggests that experience of this program shows how use of the transformative model, in particular, could be valuable not only for clinical education but also for effective volunteer training and supervision in mediation programs generally.     

Online collaboration as a pedagogical approach to learning and teaching undergraduate legal education

Legal education is in a period of rapid development driven by changing industry demands and developing technologies. This paper will describe an innovative pilot study which utilises new technologies to provide an alternative mode of teaching and learning to meet growing industry demands for graduates who are technologically savvy and have strong communication and collaboration skills. The pilot study redesigns a law unit combining a more traditional approach with an approach in which online collaboration is critical to student learning as a teaching and assessment tool. After completing an online collaborative activity as part of their assessment for the unit, students completed an online survey to identify their perspectives of the online collaborative experience. The online survey data was analysed to identify common themes and the experiences of students are shared in this paper. The paper provides an example of how instructors might take advantage of a learning design process, online tools and infrastructure to develop educational experiences which promote communication and collaboration within the law discipline. It will also include five recommendations to consider when including online collaboration in unit design for law students.     

Evaluation of Commercial‐off‐the‐Shelf Materials for the Preservation of Bacillus anthracis Vegetative Cells for Forensic Analysis,

Environmental surface sampling is crucial in determining the zones of contamination and overall threat assessment. Viability retention of sampled material is central to such assessments. A systematic study was completed to determine viability of vegetative cells under nonpermissive storage conditions. Despite major gains in nucleic acid sequencing technologies, initial positive identification of threats must be made through direct culture of the sampled material using classical microbiological methods. Solutions have been developed to preserve the viability of pathogens contained within clinical samples, but many have not been examined for their ability to preserve biological agents. The purpose of this study was to systematically examine existing preservation materials that can retain the viability of Bacillus anthracis vegetative cells stored under nonpermissive temperatures. The results show effectiveness of five of seventeen solutions, which are capable of retaining viability of a sporulation deficient strain of B. anthracis Sterne when stored under nonrefrigerated conditions.     

The Process is the Punishment: Criminal Libel and Political Speech in Canada

The number of U.S. states with criminal libel laws has been steadily declining since the 1960s, and the offense has been struck down in the United Kingdom and several former British colonies. In Canada, however, criminal libel not only continues to exist, but appears to be enjoying a resurgence, albeit one that has flown beneath the radar of Canadian lawyers, judges, and journalists, who frequently assert that criminal libel prosecutions are rare. The research reported in this article found more than 400 prosecutions since the beginning of the twenty-first century. While many of these cases were brought against people who disseminated sexual slurs against former romantic partners, in a substantial number of cases criminal libel law was used to punish citizens’ political speech, particularly speech critical of police or other justice system officials, a use wholly inconsistent with the Canadian Charter of Rights and Freedoms.     

Social capital in Scottish and Danish neighbourhoods: paradoxes of a police–community nexus at the front line

Community-oriented social capital strategies and punitive-oriented policing approaches conflict. Establishing local networking initiatives with community-oriented policing at the centre lends itself to an assets-based policing approach, based on honouring, mobilizing and extending the assets of community members. Scholars argue about the need for comparative research on convergences and divergencies across subcultures on the streets and communities. Based on qualitative data gathered from working class communities in Scotland and Denmark in 2014, the article draws inspiration from community-generated theory of social capital to explore the micro-sociology of experiences and understandings about community–police integration policy initiatives. We use this perspective to argue that the building of positive inter-generational and police–community relationships is the result of social exchanges and officers’ use of what we call ‘constructive investment strategies’. Ironically, our insights from Scotland to Denmark also suggest what appear as positive achievements of community policing may instead intensify residents’ negative perceptions of police officers and organizations. In this way, the article illuminates the tangled and conflicted nature of these embedded symbolic interactions, social capital formations and the latter’s form as a potential positional and ‘tribal’ commodity.     

A prospective study of pathways to hospital readmission in Canadian forensic psychiatric patients

Individuals admitted to secure care often experience lengthy hospitalizations and are likely to be admitted on more than one occasion. In the context of growing demand and costs associated with secure care, the current study investigates the frequency and reasons for readmission among 87 forensic patients recently discharged into the community. We identify risk factors that are associated with the likelihood of readmission and describe areas of overlap and discordance with the existing literature in civil and forensic samples. Using a prospective design that included patient follow-up interviews and records review, we found that 28% of patients were readmitted on one or more occasions over a 12-month period. Psychiatric decompensation, substance use, and treatment non-adherence were the central reasons prompting readmission. Patients with one or more readmissions were found to have spent significantly more time in the forensic mental health system as compared to patients not readmitted. They were more likely to have a substance use disorder and were estimated to be at higher risk for violence. Results replicate the finding of low rates of serious violence and reoffending among discharged forensic patients, and substantiate the centrality of substance use as a growing and clinically important treatment issue.     

The Language of Miranda Warnings in American Jurisdictions: A Replication and Vocabulary Analysis

Miranda warnings are remarkably heterogeneous in their language, length, and content. Past research has focused mostly on individual Miranda warnings. Lacking in generalizability, these studies have limited applicability to both public policy and professional practice. A large-scale survey by R. Rogers et al. [2007b, Law and Human Behavior, 31, 177-192] examined Miranda warnings from across the United States and documented striking differences in the length, content, and reading comprehension. In moving from single jurisdiction studies to nationally representative research, the replication of the Rogers et al. survey is essential. With an additional 385 general Miranda warnings, most of the original findings were confirmed; this replication allows Miranda researchers to use findings based upon nationally-representative warnings for their subsequent research. Beyond reading comprehension, the study makes an original contribution to the understanding of Miranda vocabulary that is often infused with abstruse words and legalistic terms. It provides the first analysis of sentence complexity, which affects both Miranda comprehension and retention. As a result of these analyses, preliminary guidelines are provided for increasing the comprehension and understanding of Miranda warnings.
