Interstate tax competition after TRA86

When a governor announces that a tax increase is necessary, how do voters decide whether the governor is representing the situation honestly, or just preparing to line his or her pockets? This paper presents evidence that voters may look at the tax increases in neighboring states to obtain information on whether a tax increase is appropriate and, using this information, decide whether to reelect their governor. The data suggest that comparisons with neighbors influence gubernatorial behavior: Governors are more likely to raise taxes when neighbors are doing the same. TRA86 allows us an extra check on the rnodelpresented: I f the marginal dollar taken in state taxes is more costly to state residents, this may increase the extent to which residents use information provided through neighboring states to sort good governors from bad.     

Networks of Reciprocity: Precarity and Community Social Organisations in Rural Myanmar

ABSTRACT

Growing precarity amongst rural households in Myanmar is characterised by increasingly debt-fuelled agriculture, decreasing sufficiency and sustainability of rural livelihoods and an absence of social safety nets. This constrains the capacity for viable livelihoods, as risk-averse coping strategies undermine long-term economic sustainability. In this context, informal support networks may be expected to decline or collapse. However, recent evidence demonstrates the widespread emergence of community-based social organisations in rural communities, formed along traditional principles of reciprocity. Analysis of large-scale rural household surveys demonstrates that such organisations are found in nearly 40% of communities in rural Myanmar. These organisations collect and redistribute funds to help with healthcare, education, funerals and other social needs. The presence of such organisations is linked to higher levels of household resilience, achieved through reducing the inequalities linked to gender, disability and poverty, and through providing enabling environments for effective income diversification. Communities with higher levels of migration are more likely to have community-based social organisations, possibly a result of economic and social remittances. In the absence of effective formalised social protection, these social organisations provide most of the social assistance in rural communities, representing new networks of reciprocity in the face of increasing precarity.     

STR analysis of artificially degraded DNA-results of a collaborative European exercise

Degradation of human DNA extracted from forensic stains is, in most cases, the result of a natural process due to the exposure of the stain samples to the environment. Experiences with degraded DNA from casework samples show that every sample may exhibit different properties in this respect, and that it is difficult to systematically assess the performance of routinely used typing systems for the analysis of degraded DNA samples. Using a batch of artificially degraded DNA with an average fragment size of approx. 200 bp a collaborative exercise was carried out among 38 forensic laboratories from 17 European countries. The results were assessed according to correct allele detection, peak height and balance as well as the occurrence of artefacts. A number of common problems were identified based on these results such as strong peak imbalance in heterozygous genotypes for the larger short tandem repeat (STR) fragments after increased PCR cycle numbers, artefact signals and allelic drop-out. Based on the observations, strategies are discussed to overcome these problems. The strategies include careful balancing of the amount of template DNA and the PCR cycle numbers, the reaction volume and the amount of Taq polymerase. Furthermore, a careful evaluation of the results of the fragment analysis and of automated allele calling is necessary to identify the correct alleles and avoid artefacts.     

Sexual and nonsexual offenders with intellectual and learning disabilities: a comparison of characteristics, referral patterns, and outcome

This article reports an evaluation of a community intellectual disability offender service over the period from 1990 to 2001. Men who committed sex offenses or sexually abusive incidents (n = 106) and men who committed other types of offenses and serious incidents (n = 78) are compared on personal characteristics, referral sources, forensic details, and outcome up to 7 years after referral. The cohorts are older than one would expect from the criminology literature, and, at about 33%, the incidence of mental illness is consistent with some previous studies. A greater proportion of sex offenders had criminal justice involvement and a formal disposal from court. Fire raising was not overly represented as an offense. There was a higher rate of reoffending in the nonsexual cohort, which persisted up to 7 years. Investigating only reoffenders, there was a considerable amount of harm reduction recorded up to 7 years, statistically significant up to 5 years following initial referral.
