Comparison of two methods for isolating DNA from human skeletal remains for STR analysis

Abstract: The quality and efficiency of a standard organic DNA isolation method and a silica‐based method using the QIAGEN Blood Maxi Kit were compared to obtain human DNA and short tandem repeats (STRs) profiles from 39 exhumed bone samples for paternity testing. DNA samples were quantified by real‐time PCR, and STR profiles were obtained using the AmpFlSTR^® Identifiler^® PCR amplification kit. Overall, the silica‐based method recovered less DNA ranging from 0 to 147.7 ng/g (average 7.57 ng/g, median = 1.3 ng/g) than did the organic method ranging from 0 to 605 ng/g (average 44.27 ng/g, median = 5.8 ng/g). Complete profiles (16/16 loci tested) were obtained from 37/39 samples (95%) using the organic method and from 9/39 samples (23%) with the silica‐based method. Compared with a standard organic DNA isolation method, our results indicate that the published silica‐based method does not improve neither the quality nor the quantity of DNA for STR profiling.     

Watch for those fragments of evidence: the use of an automatic timepiece to help correlate a helicopter crash site from the Vietnam War

This case study illustrates the use of the date function on an automatic wristwatch to help identify a Vietnam War helicopter crash site. The location of a crash incident can sometimes be uncertain because of inadequate or inaccurate wartime records and the passage of time. Artifacts recovered from a prospective crash scene are regularly used to correlate the loss incident. In this case study, a recovered automatic watch displayed a date 2 days later than the reported loss incident. Although the date conflicts with the aircraft crash incident report, it is observed that a fully wound automatic watch continues to work for c. 2 days after movement of the watch ceases. Thus, the watch's date in fact correlates with the aircraft crash incident report. It is noted that automatic watches may also be used to date scenes of crime.     

Decaying Mouse Volatiles Perceived by Calliphora vicina Rob.‐Desv.

Volatiles emitted by decaying human remains are in the focus of recent research. The identification of core volatiles in this field is of high importance, because cadaveric volatiles generally show high variation. In this study, the volatile profiles of five mice (Myodes glareolus) were sampled with charcoal filter tubes from their time of death until advanced decay. Eleven compounds were quantitated by means of gas chromatography–mass spectrometry. Electroantennographic experiments with female Calliphora vicina antennae led to the identification of dimethyl trisulfide, dimethyl disulfide, nonanal, hexan‐1‐ol, 1‐octen‐3‐ol, 3‐methylbutan‐1‐ol, and heptanal as electrophysiologically active compounds. When these were compared, dimethyl trisulfide (17 ng/μL) and dimethyl disulfide (11 ng/μL) were found to be emitted in higher concentrations. The roles of these compounds and nonanal as core volatiles for cadaver detection or postmortem time determination and their correlation to the stages of decay and the accumulated degree days are discussed.     

Family Group Conferencing and Re‐Offending Among First‐Time Juvenile Offenders: The Indianapolis Experiment

Restorative justice processes, and family group conferences in particular, have become increasingly common in justice system practices across the globe. There has also been significant scholarly interest. Yet, with several notable exceptions, much of the research has been characterized by relatively weak designs, and questions related to the impact of family group conferences on re‐offending remain unanswered. This research is intended to begin to address these issues. The study is based on an experiment conducted in Indianapolis, Indiana whereby young, first‐time‐offending youths were randomly assigned to either a family group conference or one of a number of court‐ordered diversion programs. Nearly 800 youths participated in the experiment, and the cases were tracked for 24 months following their initial arrest. Survival analysis techniques were used to compare prevalence patterns of re‐offending among the treatment and control groups. The results indicated a significant difference between the two groups with the control group experiencing higher rates of failure (re‐offending). The differences were most pronounced during the period of 3–8 months following the initial arrest. Incidence rates were also compared. Assignment to the treatment group was negatively related to incidence of offending. Given the consistent finding of victim benefits in restorative justice processes, the results suggest that conferences hold promise as an effective intervention, at least for young first‐time offenders, and warrant continued experimentation.     

Windows Surface RT tablet forensics

Small scale digital device forensics is particularly critical as a result of the mobility of these devices, leading to closer proximity to crimes as they occur when compared to computers. The Windows Surface tablet is one such device, combining tablet mobility with familiar Microsoft Windows productivity tools. This research considers the acquisition and forensic analysis of the Windows Surface RT tablet. We discuss the artifacts of both the Windows RT operating system and third-party applications. The contribution of this research is to provide a road map for the digital forensic examination of Windows Surface RT tablets.

The spaces of intervention for Mali and Guinea-Bissau

ABSTRACT

This article focuses on interventions by the African Union and the Economic Community of West African States in Guinea-Bissau and Mali. In the literature, these are often approached in a ‘top-down’ manner, focusing on formal institutions, not accounting for the complex dynamics in and around conflict intervention. This article argues that adopting space as an analytical lens allows new ways to address these issues. It highlights how interventions by different actors and their interactions are influenced by spatial perceptions and framings, which result in the making of different ‘spaces of intervention’ through different practices. The two described here, ‘scaling’ and ‘establishing reach’, enable strategic and continuous formation and negotiation of spaces for action, according to actors’ needs and interests. Thus, shedding light on specific actors and their practices, the article contributes to a better understanding of the complex dynamics in conflict intervention in West Africa.     

Timing is everything: a quantitative study of presidentialist regime dynamics in Eurasia, 1992–2016

Why do some countries with presidentialist constitutions feature more political closure than others at a given time? A quantitative study of post-Soviet countries since independence finds that much of the observed variation in political closure reflects timing, or the particular point at which a country happens to be within a regime cycle, rather than structural or other factors usually cited to explain regime change. Specifically, how much time a president has had to coordinate rivalrous networks around his or her authority is at least as strong a predictor of the level of regime closure as are economic development, economic growth, resource rents, proximity to Europe, and key cultural factors, even when controlling for the level of closure in the preceding year. This pattern is not found among countries with divided-executive constitutions, indicating it is related to the constitution rather than a general phenomenon.
