Typeability of AmpFlSTR SGM Plus loci in brain and thyroid gland tissue samples incubated in different environments

Autolysis and putrefaction are crucial factors responsible for degradation of cells, tissues, and organs. Postmortem changes may assume different course depending on extrinsic and intrinsic conditions. The aim of the study was assessment of environmental effect on typeability of AmpFlSTR SGM Plus loci: D3S1358, VWA, D16S539, D2S1338, D81179, D21S11, D18S51, D19S433, TH01, FGA, and gender marker amelogenin. Brain and thyroid gland tissue specimens collected during autopsies of five persons aged 20-30 years were incubated at 21 degrees C and 4 degrees C in different environmental conditions. DNA was extracted by organic method from tissue samples collected in 7-day intervals and subsequently typed using AmpFlSTR SGM Plus kit and ABI 310. A fast decrease in typeability rate was seen in specimens incubated in peat soil and in sand. Brain tissue samples were typeable in all AmpFlSTR SGM Plus loci within 126 days of incubation at 4 degrees C. Faster DNA degradation was recorded in thyroid gland specimens. In samples with negative genotyping results, no DNA was found by fluorometric quantitiation.     

Youth justice conferencing and indigenous over-representation in the Queensland juvenile justice system: a micro-simulation case study

Restorative justice conferencing for young offenders is firmly established in Australian juvenile justice, and legislated conferencing schemes are operating in all Australian states and territories. While there is some variation in the terms used to describe restorative justice conferences (e.g., family group conferencing, family conferencing, or youth justice conferencing), there is much more consistency in how the conferencing process is managed across Australian jurisdictions. In Queensland youth justice conferencing is a process that brings together an offender, the victim and their supporters to discuss the harm caused by the offending behaviour and provide the young person with an opportunity to take responsibility for his or her behaviour and make amends. This paper begins by briefly sketching the development of restorative justice conferencing in Queensland and describes the Juvenile Justice Simulation Model (JJSM), a micro-simulation model developed for criminal justice policy analysis in Queensland, Australia. We use this micro-simulation model to conduct an experimental exploration of the effects that youth justice conferencing has on system-wide outcomes for indigenous young people. The model simulates the impact of interventions up until 2011 on the number of finalised youth justice court appearances. Our results indicate that youth justice conferencing is unlikely to reduce the over-representation of indigenous young people in the juvenile justice system. The simulations demonstrated that, by the 2011, youth justice conferencing would result in a 12.5% decrease in finalised court appearances. Unfortunately, this decrease was more apparent for non-indigenous young people (13.7% decrease in court appearances) than for indigenous young people, who had a 10.5% decrease in court appearances. This differential impact of conferencing is due to the different court appearance profiles between indigenous and non-indigenous young offenders, with indigenous young people initiating offending at an earlier age and offending more frequently than non-indigenous young offenders.     

Perceptions about memory reliability and honesty for children of 3 to 18 years old

Purpose. To examine the relationship between perceived memory characteristics and age. Method. Participants rated the reliability and honesty of children's memory for one of two events. The children's ages varied from 3‐ to 18‐years‐old. Results. Participants (N = 612) believed that memory reliability increased with age, but the observed effect was non‐linear. Perceived reliability increased rapidly for children from 3 to 6 years. After this, male participants believed memory reliability increased, but less than in early childhood. Female participants did not think memory reliability increased in middle childhood and adolescence. Further effects involving type of event, age of participant, and the gender of the eyewitness were observed for honesty and the relationship between these attributes and beliefs in guilt. Conclusions. These findings stress the need for more research on development trends of memory in middle childhood and adolescence.     

Transfer of academic research: uncovering the grey zone

In this study, we respond to calls for further investigation on why and how scientists choose to commercialize their research. Mowery (University entrepreneurship and technology transfer: process design, and intellectual property, Elsevier, Oxford 2005), in his criticism of the US-system, emphasizes the need for multiple channels between university and industry. His argument makes the case of Sweden interesting, where the researchers own the intellectual property of their research. Sweden thus constitutes a unique case where data can be found on which choices researchers make in a setting where a variety of channels for transfer are available. Our empirical data, collected through case studies, allowed for the expansion of the typology for mechanisms for transfer of academic research as well as the development of a typology for determinants for researchers’ choice to engage in transfer of research. Apart from those contributions to the theoretic discussion, the data also provided policy implications.     

Service delivery on the cheap? Community-based workers in development interventions

Within current neo-liberal approaches to development, models of community-driven development assume that community-based workers (CBWs) are key actors in improved and accessible service delivery. We argue that use of CBWs is under-theorised and seems to be based largely on untested assumptions about community participation and responsibility. Drawing on case studies on potable-water management and home-based care for HIV/AIDS patients in Tanzania and South Africa, the article explores issues of accountability, professionalism, and personal motivations in systems involving CBWs. It argues that many assumptions in relation to the effectiveness of CBW programmes require re-visiting.     

Linking arson incidents on the basis of crime scene behavior

The present study investigated the possibility of statistically linking arson cases based on consistency of behaviors from one crime scente to another. Serial and spree arson cases were studied to differentiate underlying themes and to link cases committed by the same offender. The material consisted of 248 arson cases which formed 42 series of arsons. A content analysis using 45 dichotomous variables was carried out and principal compnents (PCA) analysis was performed to identify underlying themes. Summary scores reflecting the themes were calculated. Linking effectiveness was tested with a discriminant analysis using the summary scores. The PCA analysis was successful and underlying themes which were in accordance with previous studies could be identified. Six factors were retained, in the PCA. The linking of the arson cases was possible to a satisfactory level: 33% of the cases could be correctly linked and for over 50% of the cases, the series they actually belonged to was among the ten series identified as most probable on the basis of the linking analysis. From a practical point of view, the results could be used as a basis for developing support systems for police investigations of arson. This research was financially supported by the Finnish Ministry of Interior and by Grant 54456 from the Academy of Finland.
