Evaluation of a semi-automated, magnetic bead-based DNA extraction method for genetic fingerprinting of forensic casework samples

In order to cope with the demanding workload for DNA profiling of forensic casework samples a concept for a semi-automated processing system was developed at the Landeskriminalamt (Office of Criminal Investigation) Baden-Württemberg, Germany [K. Vollack, et al., Implementation of a semi-automated processing system for DNA profiling of forensic casework samples, this issue]. The applied magnetic bead extraction method is based on ChargeSwitch^® Technology (CST) from Invitrogen and was established on a liquid handling workstation Freedom EVO^® 150 from Tecan.     

1989 and Post-Cold War Policymaking: Were the “Wrong” Lessons Learned from the Fall of Communism?

Twenty years after the events of 1989, most American academics and policymakers continue to see the end of the Cold War as a victory for the United States. This Cold War “triumphalism” is based on a number of assumptions which have, in turn, served as important framing devices for US foreign policy. This chapter argues that the “wrong lessons” were learned from the fall of communism in Central and Eastern Europe. These lessons were based on a misreading of both Cold War history, in general, and its endgame, more specifically. This chapter outlines ten such lessons and explores the ways in which they were used to legitimate policies of regime change from above after 9/11. In this way, we can see a direct line between Berlin in 1989 and Baghdad in 2003, one driven by the hubris of both US policymakers and intellectuals.     

Living victims of strangulation: a 10-year review of cases in a metropolitan community

The prevalence of reported domestic violence or intimate partner violence has greatly increased, with approximately 1.5 million women violently assaulted annually in the United States by an intimate partner. Strangulation is often seen in violence against women, including domestic violence cases. Strangulation is defined as "a form of asphyxia characterized by closure of the blood vessels or air passages of the neck as a result of external pressure on the neck." This is a 10-year case review of 102 living victims of strangulation who underwent medicolegal evaluation at the Clinical Forensic Medicine Program at a State Medical Examiner's Office serving Southern Indiana and all of Kentucky. The majority of victims (79%) were strangled by an intimate partner, and manual strangulation was the most common method (83%). A total of 38 victims (38%) described a history of domestic violence, and the same number lost consciousness while being strangled. Nine (9%) women were pregnant at the time of the attack, while 13 (13%) had a history of being sexually abused in addition to being strangled. A paucity of cases involved only strangulation, as most of the victims were subjected to myriad forms of blunt force trauma which included not only the head and neck but also other bodily regions. This is a unique presentation of strangulation of living persons as most evidence of strangulation in the forensic literature has been derived from postmortem examinations of the victims. This comprehensive study discussing the examination of a living strangulation victim offers valuable insight into the mechanism and the physical findings involved in the strangulation process.     

The impacts of the Virginia Tech and Northern Illinois University shootings on fear of crime on campus

There has been a substantial increase in the number of mass shooting incidents on college campuses in the United States in recent years. Although empirical research examined the impacts of secondary school shootings on student fear, there have been no comparable studies of the impacts of campus shootings. This study began to fill this void by examining responses to surveys administered to convenience samples of students enrolled at the University of South Carolina prior to and following the mass shooting incidents on the campuses of Virginia Tech and Northern Illinois University. Findings indicated that both shootings were associated with modest increases in various measures of fear. Other findings were that the impacts of the shootings depended on both the type of fear measured (e.g., general fear versus fear of being a victim of specific crimes) and student characteristics such as age, sex, and race.     

Adult guardianship: human rights or social justice?

Adult guardianship in English-speaking countries has its roots firmly planted in the protective parens patriae principle. In the last 20 years, in response to societal changes and international developments, concerns about human rights have fundamentally challenged the historic basis of guardianship. This article argues that social justice offers a better framework than human rights for adult guardianship legislation.     

The Initial Changes of Fat Deposits During the Decomposition of Human and Pig Remains

Abstract:  The early stages of adipocere formation in both pig and human adipose tissue in aqueous environments have been investigated. The aims were to determine the short-term changes occurring to fat deposits during decomposition and to ascertain the suitability of pigs as models for human decomposition. Subcutaneous adipose tissue from both species after immersion in distilled water for up to six months was compared using Fourier transform infrared spectroscopy, gas chromatography-mass spectrometry and inductively coupled plasma-mass spectrometry. Changes associated with decomposition were observed, but no adipocere was formed during the initial month of decomposition for either tissue type. Early-stage adipocere formation in pig samples during later months was detected. The variable time courses for adipose tissue decomposition were attributed to differences in the distribution of total fatty acids between species. Variations in the amount of sodium, potassium, calcium, and magnesium were also detected between species. The study shows that differences in total fatty acid composition between species need to be considered when interpreting results from experimental decomposition studies using pigs as human body analogs.     

Public Intellectuals and Think Tanks: A Free Market in Ideas?

The paper critically evaluates the thesis of the interchangeability between the think-tank public intellectual and the academic public intellectual. It suggests that this thesis, while endorsing the rise of the think-tank public intellectual, pronounces the salience of the intellectual-social critic and undermines the authority of academic public intellectuals. It is argued that the think-tank expert doubling as the public intellectuals could limit the political relevance of the academic public intellectual and that the think-tank expert’s monopolization of the public forum could present a threat to the quality of public debates. While recognizing that there are many contradictions inherent in the role of intellectual and that there are now numerous factors that hinder the abilities of academics to act as public intellectuals, the paper emphasizes public academic intellectuals’ contribution to the dynamics of public opinion and the quality of democratic standards. In today’s context, with the omnipresent of media, the new conditions of knowledge production, the neo-liberal ethos and the social prominence of think-tank experts, the sources of the academic public intellectual authority are in a continuous need for reinvestment.     

DNA Profiles from Fingerprint Lifts—Enhancing the Evidential Value of Fingermarks Through Successful DNA Typing

This study evaluated the compatibility of the most common enhancement methods and lifting techniques with DNA profiling. Emphasis is placed on modern lifting techniques (i.e., gelatin lifters and Isomark?) and historical fingerprint lifts for which limited research has been previously conducted. A total of 180 fingerprints were deposited on a glass surface, enhanced, lifted, and processed for DNA typing. DNA could be extracted and profiled for all the powders and lifts tested and from both groomed fingerprints and natural prints with no significant difference in the percentage of profile recovered. DNA profiles could also be obtained from historical fingerprint lifts (79.2% of 72 lifts) with one or more alleles detected. These results demonstrate the compatibility between different powder/lift combinations and DNA profiling therefore augmenting the evidential value of fingerprints in forensic casework.
