Recovery of decomposed and skeletal human remains in the "Green River Murder" Investigation. Implications for medical examiner/coroner and police

The Green River Murder Investigation in King County, Washington, is currently the longest active serial murder investigation in U.S. history. During its course, over 26 separate scenes with from one to five victims each have been processed. The experience of the authors is presented in order to acquaint other agencies with techniques of outdoor scene processing that have evolved during recovery of remains from Green River and other skeletal cases.     

Probable posttraumatic stress disorder in a sample of urban jail detainees

This study examined the nature and extent of probable posttraumatic stress disorder (PTSD) among men in a substance abuse treatment program in a large urban jail. Specifically, it explored the prevalence of probable PTSD and other psychiatric problems among jail detainees, the types of trauma detainees experienced during different phases of their lives, and how those experiences might have contributed to the development of probable PTSD. Results showed that psychiatric problems were quite serious; nearly one-quarter of the sample reported previous psychiatric hospitalization, and nearly 10% were being currently treated with psychiatric medication. In addition, 21% of the sample met the criteria for probable PTSD, a rate five times greater than that in the general population. The current study suggests that the presence of probable PTSD among male detainees should be incorporated into the creation and implementation of jail-based behavioral healthcare services, including screening, assessment, and clinical interventions. Furthermore, in-custody drug treatment programs should adopt trauma-informed strategies for all program participants as the expected standard of care.     

Governing health and safety at lower tiers of the computer industry global value chain

Global brands remain under increasing pressure to ensure labor standards and codes of conduct are met by their suppliers. Little is known about how this is addressed by lower tier suppliers. We investigate whether, and how, occupational health and safety standards permeate down the computer industry value chain. We compare first and second tier suppliers' engagement with a private voluntary industry code, the Electronic Industry Code of Conduct, and the publicly regulated European Union Directive on the Restriction of Hazardous Substances. We find the industry code absent at the lower tier, yet second tier suppliers do implement the European Union Directive. This is achieved without support from public agencies or global value chain linkages. Our findings question the emphasis placed on chain governance in studies of labor compliance in global value chains, and suggest that alternative and complementary approaches may be required for effective labor compliance throughout the value chain.     

Young adults’ conceptions of ‘good’ citizenship behaviours: a latent class analysis

Democracies need an active civic society, and early adulthood is a significant period in life for becoming an engaged citizen. The research reported on here categorized young Australians according to their conceptions of good citizenship using latent class analysis. Half of the sample were characterized as either ‘engaged’ or ‘duty-based,’ suggesting that there is more to consider when talking about citizenship norms and value changes, as the other half comprised ‘enthusiastic’ and ‘subject’ citizens. Prior participation was almost unrelated to those citizenship norms. The findings provide implications for an active citizenry, and the discussion addresses limitations and directions for future research.     

Analysis of mitochondrial SNPs in addition to conventional STR-typing in a case of aggravated theft

In the field of forensic DNA typing, the analysis of Short Tandem Repeats (STRs) can fail in cases of degraded DNA. The typing of coding region Single Nucleotide Polymorphisms (SNPs) of the mitochondrial genome provides an approach to acquire additional information. In the examined case of aggravated theft, both suspects could be excluded of having left the analyzed hair on the crime scene by SNP typing. This conclusion was not possible subsequent to STR typing. SNP typing of the trace on the torch light left on the crime scene increased the likelihood for suspect no. 2 to be the origin of this trace. This finding was already indicated by STR analysis. Suspect no. 1 was excluded for being the origin of this trace by SNP typing which was also indicated by STR analysis. A limiting factor for the analysis of SNPs is the maternal inheritance of mitochondrial DNA. Individualisation is not possible. In conclusion, it can be said that in the case of traces which cause problems with conventional STR typing the supplementary analysis of coding region SNPs from the mitochondrial genome is very reasonable and greatly contributes to the refinement of analysis methods in the field of forensic genetics.     

Profiles of Adolescents’ Perceptions of Democratic Classroom Climate and Students’ Influence: The Effect of School and Community Contexts

Students’ learning experiences and outcomes are shaped by school and classroom contexts. Many studies have shown how an open, democratic classroom climate relates to learning in the citizenship domain and helps nurture active and engaged citizens. However, little research has been undertaken to look at how such a favorable classroom climate may work together with broader school factors. The current study examines data from 14,292 Nordic eighth graders (51% female) who had participated in the International Civic and Citizenship Education Study in 2009, as well as contextual data from 5,657 teachers and 618 principals. Latent class analysis identifies profiles of students’ perceptions of school context, which are further examined with respect to the contextual correlates at the school level using two-level fixed effects multinomial regression analyses. Five distinct student profiles are identified and labeled “alienated”, “indifferent”, “activist”, “debater”, and “communitarian”. Compared to indifferent students, debaters and activists appear more frequently at schools with relatively few social problems; being in the communitarian group is associated with aspects of the wider community. Furthermore, being in one of these three groups (and not in the indifferent group) is more likely when teachers act as role models by engaging in school governance. The results are discussed within the framework of ecological assets and developmental niches for emergent participatory citizenship. The implications are that adults at school could enhance multiple contexts that shape adolescents’ developmental niches to nurture active and informed citizens for democracies.     

An already archived latent fingerprint as a DNA source for STR typing in a murder case

Former studies have shown that even a single skin contact, resulting in a latent fingerprint, can transfer enough DNA for genetic analysis. However, up to now latent fingerprints have usually not been used for DNA typing. In the present case the smeared trace of a hand was found in the suspect's car and archived. As it could not be evaluated in a classical manner, the evidence had to be examined by molecular genetic methods. DNA was extracted and typed in five different STR loci. Based on the yielded results, the significance of the findings is discussed.     

The Achilles tendon as a DNA source for STR typing of highly decayed corpses

Forensic criminal casework often involves DNA profiling of human postmortem tissues, whereas degradational processes can affect PCR-based Short Tandem Repeat (STR) analysis. Degradation of DNA is observed to vary among different tissues and with time. Therefore, the stability of DNA in Achilles tendon samples is compared to that in muscle and kidney specimens with a variety of postmortem histories. Tissue samples from 28 autopsy cases, including 15 decomposed corpses and a control group of 13 nondecayed corpses were analysed. DNA was isolated using the All-tissue DNA Kit (GEN-IAL, Troisdorf, Germany), quantified by spectrophotometric measurement, amplified by the multiplex PCR genRES MPX-2 (Serac, Bad Homburg, Germany), and analysed on the ABI PRISM 310 Genetic Analyzer (Applied Biosystems, Darmstadt, Germany). Quantitative analysis of nondecomposed tissues revealed that the recovery of DNA was highest in kidney followed by muscle, whereas Achilles tendon tissue was the poorest source of isolated DNA. Only small amounts of DNA were present in both kidney and muscle samples from decomposed corpses. However, from decayed Achilles tendon samples twice as much DNA as from nondecayed samples could be isolated on average. These results suggest DNA to be better protected in Achilles tendons. Moreover, postmortem changes in Achilles tendons may even improve DNA isolation.     

Broadening the Evaluation of Dispute Resolution: Context and Relationships Over Time

Evaluation of negotiation outcomes tends to focus on measurable, dyadic,short-term resolutions of conflict. We review current challenges to this traditionalmodel of the evaluation of dispute resolution outcomes, and we offerfour perspectives that can help address them. First, we advocate the needfor longitudinal studies of negotiations that incorporate disputant relationshipsbefore and after a particular negotiation. Second, we highlight theincreasing importance of third parties in resolving conflict. Third, we suggesta more comprehensive conception of parties, relationships andoutcomes in negotiations research. Finally, we advance an explicit incorporationof context and culture into dispute resolution research models.     

Archived or directly swabbed latent fingerprints as a DNA source for STR typing

Former studies [Nature (1997) 387, Electrophoresis 20 (1999) 2870, P. Van Renterghem, D. Leonard, C. De Greef, Progress in Forensic Genetics, Vol. 8, 2000, p. 501, J. Forensic Sci. 45 (3) (2000) 687] have shown that even a single skin contact, documented by a latent fingerprint, can transfer enough DNA for a genetic analysis. It was proven in these studies that it is possible to swab fingerprints from surfaces [Nature (1997) 387, Electrophoresis 20 (1999) 2870, P. Van Renterghem, D. Leonard, C. De Greef, Progress in Forensic Genetics, Vol. 8, 2000, p. 501] and use them as a DNA source. Usually, however, discovered fingerprints are removed with scotch tape and placed on evidence cards for further investigation.In this study, we tried to assess the potential use of latent fingerprints as a DNA source for STR typing. The materials (magnetic powder, soot powder and scotch tape) used for visualization and archiving fingerprints in Germany were tested for their PCR inhibitory characteristics. Then, fingerprints were placed on clean glass surfaces, visualized and tested for their usefulness as a DNA source.Obtained DNA was quantified and tested in an STR system. Partly it proved possible to type fingerprints taken directly from the surface as well as fingerprints removed from the surface with scotch tape.
