Observer determination of the make,model, and year of questioned vehicles

Often, criminal acts involving a vehicle are caught on digital video surveillance systems. While potentially useful for an investigation, the recording conditions are typically less than optimal for the extraction of key information for the identification of the perpetrator, such as a license plate. Providing the make, model and year of a questioned vehicle is a common request for examiners, to narrow the field of potential suspect vehicles. This study seeks to compare the performance of a nonpeer-reviewed make, model, and year determination between two separate groups, specifically, trained forensic image examiners and nontrained individuals. Results show that even with varied image capture conditions and quality, the trained forensic image examiners more correctly and completely identified the test group of questioned vehicles make, model, and year.     

The High Representative and directoires in European foreign policy: the case of the nuclear negotiations with Iran

ABSTRACT

The negotiations with Iran about its nuclear programme have seen the most protracted involvement of the High Representatives of the European Union in a high-profile policy case. This article traces the evolution of the High Representatives’ participation in the negotiations, from the first contacts with the E3 (Germany, France and the United Kingdom) in 2003 to the adoption of the Joint Comprehensive Plan of Action in 2015. It focuses on the institutional role the High Representatives played in relation with the directoires leading the talks with Iran – first the E3 and, since 2006, E3/EU. In this context, it examines the personal and organisational factors that affected the influence each of the three High Representatives (Javier Solana, Catherine Ashton and Federica Mogherini) had in regard to the directoires. The analysis distinguishes specifically between the phases before and after the 2009 Lisbon Treaty. The article shows how similar personal qualities of the three High Representatives in terms of problem-solving and trust-building gave them political capital that enabled them to adopt a fairly constant role as bridge-builders within the directoires and between the directoires and other actors. The reforms of the Lisbon Treaty had only a minor impact.     

Bringing the Falklands/Malvinas Home: Young People's Everyday Engagements with Geopolitics in Domestic Space

This paper draws on recent research examining feminist and everyday geopolitics to focus on the relatively neglected domestic sphere as a space where geopolitical events like the Falklands/Malvinas war are learnt, (re)produced, remembered and contested by young people. It presents qualitative data drawn from interviews with young people from Argentina (Río Gallegos) and the Falkland Islands (Stanley), locations with intimate connections to the 1982 war. It argues that research in domestic environments that engages the familial relations, objects and practices that embody geopolitical pasts can help make sense of how young people (are able to) express geopolitical agency.     

Responding to Severe Parent–Child Rejection Cases Without a Parentectomy: A Blended Sequential Intervention Model and the Role of the Courts

There have been significant developments over the past two decades that have expanded our understanding of the dynamics of parent–child contact problems post‐separation, which have resulted in some changes in judicial processes to respond to these cases. One significant advancement is a more sophisticated differentiation of the nature and severity of contact problems, which better assists legal and mental health professionals to provide more suitable legal and clinical interventions. However, the issue of innovative court processes has received limited attention. The authors describe a subgroup of families within the “severe” category, for whom an expanded intervention model, referred to as a Blended Sequential Intervention is proposed. This approach involves a reversal of care with court mandated therapeutic support for the rejected parent and child, but also involves the favored parent in the therapeutic plan from the outset, and is intended to avoid a permanent “parentectomy” of the child from either parent. The authors discuss how the courts should respond to these cases, and posit that until all therapeutic treatments are exhausted, interim orders should be preferred to final determinations, and judges should maintain oversight. The authors discuss the critical role of judicial leadership in working with lawyers and mental health professionals to manage and address the issues in these high conflict cases.     

Reproductive health services: “Business-in-a-Box” as a model social innovation

Access to reproductive health services and products in remote and rural communities is a critical area of concern for developing countries. This article considers a pilot intervention in three districts of Pakistan where “Business-in-a-Box” as a model of place-based social innovation is used to improve the socio-economic conditions of women in remote rural settings through socially responsible micro-franchising. It finds that such programmes help build a sense of community, ownership and grassroots capabilities and skills. The article also discusses the impacts of such actions on the individual and community life, and the need to upscale and sustain these initiatives.

Evaluating the discriminating power of amino acid ratios on distinguishing dark colored hair samples

Human hairs are one of the most commonly encountered items of trace evidence. Currently, conventional methods for hair analysis include microscopic comparison and DNA analysis (nuclear and mitochondrial). Each approach has its own drawbacks. Hair proteins are stable and offer an alternative to DNA testing, as demonstrated with proteomics for distinguishing humans. However, proteomics is complicated and requires identifying peptides to remain intact following harsh sample preparation methods. Alternatively, the actual amino acid content of a hair sample may also offer important identifying information and actually requires proteins and peptides to be broken down completely rather than remaining intact. This study evaluated the discriminating power of using hair amino acid ratios to differentiate hair samples from 10 unrelated individuals with dark colored hair. Hair proteins were digested, derivatized, and analyzed using gas chromatography–mass spectrometry. Amino acid ratios were calculated for each individual and comparisons using ANOVA and post-hoc pairwise t-test with Bonferroni correction were made with amino acid ratios for individuals. Overall, out of the 45 possible pairwise comparisons between all hair samples, 38 (84%) were differentiable. Out of the 36 possible pairwise comparisons between brown haired individuals, 32 (89%) were considered differentiable using univariate statistics. Multivariate statistics were also attempted but, overall, univariate models were sufficient for exclusionary purposes. These results indicate that amino acid ratio analysis can potentially be used as an exclusionary method using hair if DNA analysis cannot be performed, or to corroborate conclusions made following microscopic analysis.     

Characterization of an odor permeable membrane device for the storage of explosives and use as canine training aids

The storage and use of explosives is regulated at the state and federal level, with a particular focus on physical security and rigorous accounting of the explosive inventory. For those working with explosives for the training and testing of explosive-detecting canines, cross-contamination is an important concern. Hence, explosives intended for use with canine teams must be placed into secondary storage containers that are new, clean, and airtight. A variety of containers meet these requirements and include screw-top glass jars (e.g., mason jars). However, an additional need from the explosive-detecting canine community is secondary containers that can also be used as training aids whereby the volatiles emitted by explosives are emitted in a predictable and stable manner. Currently, a generally accepted method for the storage of explosives and controlled emission of explosive vapor for canine detection does not exist. Ideally, such containers should allow odor to escape from the training aid but block external contaminates such as particulates or other volatiles. One method in use places the explosive inside a permeable cotton bag when in use for training and then stores the cotton bag inside an impermeable nylon bag for long-term storage. This paper describes the testing of an odor permeable membrane device (OPMD) as a new way to store and deploy training aids. We measured the evaporation rate and flux of various liquid explosives and volatile compounds that have been identified in the headspace of actual explosives. OPMDs were used in addition to traditional storage containers to monitor the contamination and degradation of 14 explosives used as canine training aids. Explosives were stored individually using traditional storage bags or inside an OPMD at two locations, one of which actively used the training aids. Samples from each storage type at both locations were collected at 0, 3, 6, and 9 months and analyzed using Fourier Transform Infrared (FTIR) Spectroscopy and Gas Chromatography–Mass Spectrometry (GC–MS) with Solid-Phase Microextraction (SPME). FTIR analyses showed no signs of degradation. GC–MS identified cross-contamination from ethylene glycol dinitrate (EGDN) and/or 2,3-dimethyl-2,3-dinitrobutane (DMNB) across almost all samples regardless of storage condition. The contamination was found to be higher among training aids that were stored in traditional ways and that were in active use by canine teams.     

Organic impurity profiling of fentanyl samples associated with recent clandestine laboratory methods

Nearly a decade ago, fentanyl reappeared in the United States illicit drug market. In the years since, overdose deaths have continued to rise as well as the amount of fentanyl seized by law enforcement agencies. Research surrounding fentanyl production has been beneficial to regulatory actions and understanding illicit fentanyl production. In 2017, the Drug Enforcement Administration (DEA) began collecting seized fentanyl samples from throughout the United States to track purity, adulteration trends, and synthetic impurity profiles for intelligence purposes. The appearance of a specific organic impurity, phenethyl-4-anilino-N-phenethylpiperidine (phenethyl-4-ANPP) indicates a shift in fentanyl production from the traditional Siegfried and Janssen routes to the Gupta-patent route. Through a collaboration between the DEA and the US Army's Combat Capabilities Development Command Chemical Biological Center (DEVCOM CBC), the synthesis of fentanyl was investigated via six synthetic routes, and the impurity profiles were compared to those of seized samples. The synthetic impurity phenethyl-4-ANPP was reliably observed in the Gupta-patent route published in 2013, and its structure was confirmed through isolation and structure elucidation. Organic impurity profiling results for illicit fentanyl samples seized in late 2021 have indicated yet another change in processing with the appearance of the impurity ethyl-4-anilino-N-phenethylpiperidine (ethyl-4-ANPP). Through altering reagents traditionally used in the Gupta-patent route, the formation of this impurity was determined to occur through a modification of the route as originally described in the Gupta patent.     

Responding to the crisis: Eurosceptic parties of the left and right and their changing position towards the European Union

At the time of the election of the European Parliament (EP) in 2014, the European Union (EU) was heavily affected by a multifaceted crisis that had – and still has – far-reaching implications for the political system of its member countries, but also for the European level of governance. Against the background of the strong Eurosceptic vote in the 2014 EP elections, this study aims to investigate in which way Eurosceptic parties of the left and the right respond to the multiple crises of the EU. Using data from the Euromanifesto Project from 2004/2009 and 2014, changes in the party positions towards the EU are analysed in the shadow of the multiple crises and the reasons thereof are explored. The findings show a general anti-European shift among the two types of Eurosceptic parties. Nevertheless, the changes in the EU polity tone are not determined by issue-based repercussions of the multiple crises, but by the EU-related evaluation – the polity mood – of the national citizenry. For far-right Eurosceptic parties, the shift is moderated by the level of public support for EU integration in their national environment. Among far-left Eurosceptic parties, by contrast, it is moderated by the more specific public attitudes about the monetary union policy of the EU. Consequently, political parties when drafting their manifestos for EP elections are not so much guided by the objective severity of political problems or by the evaluations of these problems by the citizenry. What matters in the end is the link that citizens themselves are able to establish between the severity of political problems, on the one hand, and the responsibility of the EU for these problems on the other. This has important consequences for understanding of the nature and substance of political responsiveness within the EU system of multilevel governance.
