Trace DNA Sampling Success from Evidence Items Commonly Encountered in Forensic Casework

Trace DNA analysis is a significant part of a forensic laboratory's workload. Knowing optimal sampling strategies and item success rates for particular item types can assist in evidence selection and examination processes and shorten turnaround times. In this study, forensic short tandem repeat (STR) casework results were reviewed to determine how often STR profiles suitable for comparison were obtained from “handler” and “wearer” areas of 764 items commonly submitted for examination. One hundred and fifty‐five (155) items obtained from volunteers were also sampled. Items were analyzed for best sampling location and strategy. For casework items, headwear and gloves provided the highest success rates. Experimentally, eyeglasses and earphones, T‐shirts, fabric gloves and watches provided the highest success rates. Eyeglasses and latex gloves provided optimal results if the entire surfaces were swabbed. In general, at least 10%, and up to 88% of all trace DNA analyses resulted in suitable STR profiles for comparison.     

Voluntary policing in Sweden: media reports of contemporary forms of police–citizen partnerships

Many Western-style democracies have witnessed a general shift in the distribution of crime prevention responsibility, away from the state and increasingly to citizens themselves. Civil society is today more and more often called upon as an additional policing resource. This article explores the phenomenon of voluntary citizen participation in policing in Sweden, based on an analysis of 9280 news-media articles. One state-sanctioned (the Volunteers of the Police) and one autonomous civic (Missing People Sweden) initiative were examined, from their respective start until 2017, to understand the role played by police–citizen partnerships in the establishment and legitimation of voluntary policing forms in Sweden. A high degree of integration between police and volunteer work was found, enabling not only effective citizen participation, but also having an influence on police operations. The more effective and publicly visible the voluntary policing bodies were, the more pressure there was on the police to defend its legitimacy, ally itself with the volunteers and regulate the latter’s activities while holding them responsible for their actions. Arguably, however, with the police–citizen relationship being one of integration and mutual dependence, the division of labour and the accountability of both parties risk becoming blurred or even confused.     

Forms of technological modernization and human resources management in privatized argentine companies

After the period of hyperinflation (1989, 1990) the Argentine economy stabilized and most of public companies were privatized. The return on investments was concentrated on promoting the technological change which adopts two basic forms: systemic modernization and revamping of existing teams.

The first variant -ilustrated by the national telephone network- makes obsolete the knowledge accumulated during the period when the company was public. To confront the structural deficiency of knowledge and experience which result, the private operators invest massively in transfering educational technologies and in the development of costly and sofisticated internal systems of training, while they negotiate numerous and various agreements of cooperation with educational system institutions, public as well as private.

In the second variant - illustrated by a steel and metallurgic company - the preexisting knowledge continues being necessary even though it may need a vis-a-vis updating facing the new demands which are stated referring to the productivity, quality, effectiveness and productive efficiency in markets which are open to competition.

Taking into account the significant achievements which are being obtained by this second alternative of modernization - most of the privatized companies fall into this pattern- the article invites to a reopening of the old debate on technological blending.     

Understanding Victim Support as Crime Prevention Work: The Construction of Young Victims and Villains in the Dominant Crime Victim Discourse in Sweden

Starting from the observation that a new victim category has emerged in the form of the ‘young crime victim’, this article explores the notion of support to young crime victims as crime prevention work, considering it as an important constituent of the dominant crime victim discourse among support professionals. In the context of the support work, the (young) ‘victim’ and the (young) ‘villain’ provide mutually necessary counterparts constructed in relation to each other. Corresponding to this division, two approaches in criminal and crime prevention policy and practice are then analysed using Garland's notions of ‘the criminology of the self’ and ‘the criminology of the other’. The first of these strategies is generally associated with rehabilitative measures (with the resulting normalization of the crime, its victims, and villains), while in the second punitive measures remain the norm (with the crime, its victims, and villains becoming ‘Otherized’). Yet, as shown within the context of rehabilitation organized as support to young crime victims, both of these (at first glance mutually contradictory) discourses are drawn upon and operationalized by the professional support staff constructing images of young victims and villains in their daily work. Help-seeking youths resistant to identifying as victims remain represented as (possible future) villains.     

Genetic data on 11 STRs (CSF1PO,TPOX, TH01, F13A01, FESFPS,vWA, D16S539, D7S820, D13S317, F13B,LPL) in an Argentine northeast population

Allele frequencies for 11 short tandem repeats (STRs) loci (CSF1PO, TPOX, TH01, F13A01, FESFPS, vWA, D16S539, D7S820, D13S317, F13B and LPL) were obtained from a sample of 225 unrelated individuals born in the Entre Ríos state of Argentina.     

Forensic determination of hair deposition time in crime scenes using electron paramagnetic resonance

Several types of biological samples, including hair strands, are found at crime scenes. Apart from the identification of the value and the contributor of the probative evidence, it is important to prove that the time of shedding of hair belonging to a suspect or victim matches the crime window. To this end, to estimate the ex vivo aging of hair, we evaluated time‐dependent changes in melanin‐derived free radicals in blond, brown, and black hairs by using electron paramagnetic resonance spectroscopy (EPR). Hair strands aged under controlled conditions (humidity 40%, temperature 20–22°C, indirect light, with 12/12 hour of light/darkness cycles) showed a time‐dependent decay of melanin‐derived radicals. The half‐life of eumelanin‐derived radicals in hair under our experimental settings was estimated at 22 ± 2 days whereas that of pheomelanin was about 2 days suggesting better stabilization of unpaired electrons by eumelanin. Taken together, this study provides a reference for future forensic studies on determination of degradation of shed hair in a crime scene by following eumelanin radicals by utilizing the non‐invasive, non‐destructive, and highly specific EPR technique.     

Southern Europe and the Eurozone Crisis Negotiations: Preference Formation and Contested Issues

South European countries were severely hit by the eurozone crisis. Adopting the theoretical framework of prospect theory, this article conducts an empirical analysis of the interpretation of the situation by the South European political leaders in terms of gains and losses. After discussing the stances of South European countries vis-à-vis a number of contested issues which emerged during the 2010–2013 negotiations, the article goes on to provide a comparative account of the determinants of national preference formation with respect to the eurozone crisis reforms in Cyprus, Greece, Italy, Malta, Portugal and Spain, paying special attention to the relationship between governments and parliaments.

Health service utilization among widows living with HIV/AIDS: an interview survey in Manipur, India

Widows living with HIV/AIDS (WLHA) are a vulnerable and often overlooked group. The North Eastern Indian state of Manipur, which has one of the highest concentrations of HIV/AIDS cases in India, is not an exception. This paper aims to describe the pattern of and factors contributing to the use of health services by WLHA in Manipur. Structured face-to-face interviews were conducted among 510 respondents. Only 49% of the respondents were aware of available health facilities. The place of residence (67.8%) and appointment at a convenient time (70.8%) were the main factors affecting the use of health services. To improve access to health services, it is imperative that the services of trained health providers are made easily available. Policy makers and organizations working on HIV/AIDs should work together to remove the barriers to the use of health services, making them user friendly for vulnerable groups such as WLHA.
