TWGDAM validation of AmpFlSTR PCR amplification kits for forensic DNA casework

Laboratory procedures used in short tandem repeat (STR) analysis were subjected to various scenarios that assessed reliability and identified potential limitations. These validation studies were designed as recommended by the Technical Working Group on DNA Analysis Methods (TWGDAM) and the DNA Advisory Board (DAB) (17,18). Various DNA samples were amplified by the polymerase chain reaction (PCR) using AmpFlSTR PCR Amplification Kits (i.e., AmpFlSTR Green I, Profiler, Profiler Plus, and COfiler kits), detected with ABI Prism instrumentation, and analyzed using GeneScan and Genotyper software. Data acquired in these studies reinforced an existing body of knowledge and expertise regarding application and interpretation of STR typing in the forensic science community. Consistent STR genotypes were detected in various body tissues and fluids. Inter-laboratory comparisons produced concordant genotype results. Quantitative interpretational aids for DNA mixtures were characterized. Ability of the typing systems to type potentially compromised samples reliably was evaluated. Nonprobative case evidentiary DNA was successfully amplified, genotyped, and interpreted. Potential limitations or cautionary factors in the interpretation of minimal fluorescence intensity were demonstrated. Differential amplification between loci was observed when PCR was inhibited; preferential amplification typically was not. Single AmpFlSTR locus amplification did not offer consistent benefit over AmpFlSTR multiplexing, even in cases of DNA degradation or PCR inhibition. During rigorous evaluation, AmpFlSTR PCR Amplification Kits reproducibly yielded sensitive and locus-specific results, as required in routine forensic analyses.     

Labour Unrest in Vietnam and China: Insurgency or Contained Contention?

This article reviews three recent books on labour politics in Vietnam and China: Angie Tran’s Ties That Bind: Cultural Identity, Class and Law in Vietnam’s Labor Resistance; Jeffrey Becker’s Social Ties, Resources and Migrant Labor Contention in Contemporary China: From Peasants to Protesters, and Eli Friedman’s Insurgency Trap: Labor Politics in Post-Socialist China. These three books capture the changing patterns of labour unrest and labour institutions in Vietnam and China, which are accounted for by the social foundation of resistance as well as the political economy of capitalist development. Their main contribution to the existing literature is that they draw out the new dynamics and new venues within the state that can both enable and constrain labour resistance and struggle in these countries. However, this article also argues that these works have not adequately theorised the nature of change within the state and the role of the law in labour resistance. It therefore suggests that bringing in the law to socio-political institutions is essential to a research agenda that explores continuity and change in labour politics in Vietnam and China as transitional economies.     

Inter-Agency Cooperation to Raise Awareness on Human Trafficking in Vietnam: Good Practices and Challenges

Awareness-raising tactics are arguably the first priority in the prevention strategies in Vietnam at present. Awareness-raising campaigns are implemented through two kinds of communication methods: community-based activities and mass media. Although anti-trafficking activities in Vietnam have achieved some successful results, recent evidence suggests that a lack of clear progress in the areas of trafficking awareness-raising still remains. The quality and extent of collaboration between authorised agencies are key factors in anti-trafficking activities, including raising awareness on human trafficking. However, to date, there has been no systematic research on inter-agency cooperation in awareness-raising activities in Vietnam. This paper first reviews the nature of human trafficking and legal framework on raising trafficking awareness in Vietnam. The paper then presents successes and challenges of current inter-agency collaborative activities undertaken to implement the awareness-raising strategies.     

Do Natural Disasters Open a Window of Opportunity for Corruption?

This study explores the link between natural disasters and corruption at the local government level. We examine whether a natural disaster affects official households more favourably than non-official households. We find that natural disasters decrease nonofficial household expenditures significantly, however, they have negligible effect on official household expenditures. Meanwhile, both kinds of households experience similar reduction in incomes, and have much the same disaster coping strategies. Together, the results imply that local officials may receive unobserved monetary compensation – we define as corruption – in the aftermath of natural disasters.     

The Effects of a Housing Mobility Experiment on Participants’ Residential Environments

We used the Moving to Opportunity (MTO) housing experiment to inform how Housing Choice Vouchers and housing mobility policies can assist families living in high-poverty areas to make opportunity moves to higher quality neighborhoods, across a wide range of neighborhood attributes. We compared the neighborhood attainment of the three randomly assigned MTO treatment groups (low-poverty voucher, Section 8 voucher, control group) at 1997 and 2002 locations (4–7 years after baseline), using survey reports, and by linking residential histories to numerous different administrative and population-based data sets. Compared with controls, families in low-poverty and Section 8 groups experienced substantial improvements in neighborhood conditions across diverse measures, including economic conditions, social systems (e.g., collective efficacy), physical features of the environment (e.g., tree cover) and health outcomes. The low-poverty voucher group, moreover, achieved better neighborhood attainment compared with Section 8. Treatment effects were largest for New York, New York, and Los Angeles, California. We discuss the implications of our findings for expanding affordable housing policy.     

Coping with Precariousness: How Social Insurance Law Shapes Workers' Survival Strategies in Vietnam

This article examines the role of social insurance law in the survival strategies of factory workers in Vietnam, especially when they are faced with pressing family needs and an uncertain future. Despite the official discourse of the law which encourages employees to accumulate social insurance for their pension benefits, workers in this study have considered their social insurance fund as a form of saving and opted to gain early access to it when they are in desperate need of money. Workers understand and use the law in a way that answers to their needs; however, such action simultaneously puts them outside the protection of the law. In workers' daily struggles, law generates a moral tension between rights and needs, and ultimately perpetuates their precarious, vulnerable condition. The article demonstrates how workers' legal consciousness varies according to their perception of their precariousness, a precariousness generated by the fragile nature of their work and underpinned by their traditional familial moral obligations. This research advances our understanding of the way state law in postsocialist regimes informs social action and consciousness in ways that oftentimes contradict the spirit of the law.     

Rural-urban migration in Vietnam and China: gendered householding,production of space and the state

The transition from state socialism to market socialism in Vietnam and China has been characterized by unprecedented rural-urban migration. We argue that this migration is integral rather than incidental to the gendered reproduction of state and society. A review of the emerging literature on trans-local householding explores the process whereby the reflexive engagement of the state and the household remakes rural-urban differentiation in ways that are deeply gendered and classed. As such, state regulation and control of migrants are part of a process of reconfiguring state-society relations in which the production of space and the symbolic valuation of ruralness and urbanness have become a central trope.
