Gait analysis in forensic medicine*

Recordings from video surveillance systems are used as evidence from crime scenes. It would be useful to perform comparisons between disguised perpetrators and suspects based on their gait. We applied functional anatomical and biomechanical knowledge to analyze the gait of perpetrators, as recorded on surveillance video. Using a structured checklist, which addresses the single body segments during gait, we were able to give a statement concerning the gait patterns. Characteristic parameters were, e.g., varus instability in the knee at heel strike, and larger lateral flexion of the spinal column to one side than the other. Based on these characteristic features, we are able to state with reasonable certainty whether the suspect could be the perpetrator, but it is not possible to identify the perpetrator positively. Nevertheless, we have been involved in several cases where the court has found that this type of gait analysis was a valuable tool.     

Nordic women's documentation centres

The Norwegian au pair documentaries Mammaranet (“The Mummy Robbery”) (2006) and Herskap og tenarar (“Masters and Servants”) (2013) tell the stories of two Filipina women who have left behind their children to become au pairs in Norway. The films portray the hardship of au pairing and focus on trafficking and labour and sexual abuse. Both films are problem-orientated, and I explore the way in which they construct the figure of the au pair. I argue that the films draw on a global care chain framework to construct au pairs as mothers who are primarily financially motivated, while their children in the home country are cast as self-evidently suffering. Furthermore, the films cross-cut between stories of sexual abuse and scenes of the au pairs' highly feminized self-presentation. This cross-cutting contributes to a construction of the au pairs as vulnerable “girls”, but also as sexually available women. Using Bhattacharyya's concept of “the exotic”, I argue that this particular construction draws on a colonial discourse that makes unequal racialized power relations appear more attractive to the privileged. In conclusion, I discuss the implicit solutions to the problems presented in the films, and argue that their constructions of au pairs contribute to a certain cultural circulation of “truths” that allows for discourses favouring certain policies—namely closing the scheme to mothers and, eventually, to all au pairs from outside the EU/Schengen Area.     

ROSCA Composition and Repayment: Evidence from Taiwanese Bidding ROSCAs

Rotating savings and credit associations (ROSCAs) are widespread and remain a key financial management tool for poor individuals. We analyse data from Taiwanese bidding ROSCAs and focus on how social relationships within the group influence contribution behaviour and ROSCA failure. We find that less socially-connected participants were more likely to receive the pot early in the cycle, which increases their incentive to default, yet contrary to accepted wisdom groups including more outsiders were not more likely to experience repayment problems. Our results highlights how bidding ROSCAs can be a versatile device that provide profitable savings while allowing for emergency credit.     

PTSD symptoms and sexual harassment: the role of attributions and perceived control

Researchers have compiled significant evidence demonstrating that sexual harassment leads to psychological harm, including the full symptom picture of PTSD, but few have examined the psychological processes involved. Research on attributions among trauma victims would suggest that causal attributions and perceptions of control may be important predictors of outcomes. The authors discuss a study involving a path model that used data from 189 women involved in sexual harassment litigation. Results indicate that both self-blame and harasser blame were positively related to PTSD symptoms. Control over recovery and the perception that future harassment is unlikely were both related to fewer PTSD symptoms. Unexpectedly, perceived control over future harassment is related to higher levels of PTSD symptoms. Implications for research and practice are discussed.     

Utility of the Y-STR typing systems Y-PLEX 6 and Y-PLEX 5 in forensic casework and 11 Y-STR haplotype database for three major population groups in the United States

The Y-PLEX 6 and Y-PLEX 5 systems enable analysis for 11 Y-STR loci. We present here the utility of these systems in forensic casework. A total of 188 samples, including 127 evidence samples, were analyzed using either or both of the systems. The evidence sample types included fingernail scrapings, sperm or seminal fluid, epithelial cells, blood and other tissues. The Y-STR typing systems provided useful probative results in difficult cases. A reference database for Caucasian (n = 517), African American (n = 535), and Hispanic (n = 245) population groups within the United States was generated for estimating the haplotype frequency in forensic casework. Among the individuals profiled, 311 Caucasians, 412 African Americans, and 194 Hispanics provided unique profiles in their respective population datasets. This is the first report describing the haplotype database for the set of 11 Y-STR loci recommended by the Scientific Working Group on DNA Analysis Methods (SWGDAM). Linkage analysis reveals that the frequencies from forensically important autosomal loci can be multiplied with the Y-STR haplotype frequency. The results from Y-PLEX systems have been accepted in courts in the United States.     

Sequencing strategy of mitochondrial HV1 and HV2 DNA with length heteroplasmy

We describe a method to obtain reliable mitochondrial DNA (mtDNA) sequences downstream of the homopolymeric stretches with length heteroplasmy in the sequencing direction. The method is based on the use of junction primers that bind to a part of the homopolymeric stretch and the first 2-4 bases downstream of the homopolymeric region. This junction primer method gave clear and unambiguous results using samples from 21 individuals with length heteroplasmy in the hypervariable regions HV1, HV2 or both. The method is of special value for forensic casework, because sequencing of both strands of an mtDNA region is preferable in order to reduce ambiguities in sequence determination.     

The moving targets of penal abolitionism: ICOPA,past, present and future

The history of the International Conference on Penal Abolition (ICOPA) is explored, assessing major trends shaping the current growth of carceral practices and offering suggestions for the future of the conference movement. The goal here is to facilitate the expansion of abolitionism by describing the changing nature of what is to be abolished. A discussion of the emergence of prison abolitionism and of the ICOPA is presented, describing the shift in focus from prison to penal abolition. Taking these developments and character into account, an abolitionist gaze must be expanded to reflect a carceral abolition project, encompassing contemporary penal abolitionism while acknowledging the proliferation of carceral practices and spaces outside the traditional penal system.     

Greenland criminal justice: The adaptation of western law

The conflict which many indigenous peoples experience with Westernized systems of law has precipitated a search for alternative models of criminal justice. While the process of colonization has most often resulted in the destruction of traditional practices of social control, in Greenland an attempt was made to adapt Western law to the indigenous culture. The Greenlandic justice system has several unique attributes which have attracted the attention of indigenous peoples and governments worldwide. This article traces the origins, development and evolution of the Greenlandic Criminal Code and criminal justice system, the factors which influenced its development, and the extent to which the objectives of the architects of the systems have been met. The discussion provides key insights into the potential and limitations of adapting Western law to indigenous cultures.
