Blood group frequencies of the population of Trinidad and Tobago, West Indies.

The results of grouping tests performed on blood samples collected over a five-year period at the Trinidad and Tobago Forensic Science Centre are presented. The samples were tested using the ABO, PGM, EAP and GLO blood group systems. Phenotypic frequencies and allele frequencies for each system were calculated for the two major ethnic groups of the population, the African and East Indian. Matching probabilities, which can be used in the interpretation of physical evidence in forensic cases, were also calculated.     

HLA DQ alpha typing of forensic specimens by amplification restriction fragment polymorphism (ARFP) analysis.

The alleles present at the HLA DQ alpha locus may be typed by either allele specific oligonucleotide (ASO) probing or by restriction mapping, referred to here as amplification restriction fragment polymorphism (ARFP) analysis. ASO typing relies upon hybridization principles, whereas ARFP typing relies upon restriction site analysis. Dot-blot ASO typings which are of doubtful interpretation may be directly checked by ARFP analysis. Aliquots of the PCR products amplified using the commercial Amplitype HLA DQ alpha system are digested with suitable restriction endonucleases. Electrophoresis, blotting and detection of biotin-labelled restriction fragments provides a sensitive and robust typing method suited to forensic analysis.

Norms versus Action: Why Voters Fail to Sanction Malfeasance in Brazil

We show that Brazilian voters strongly sanction malfeasant mayors when presented with hypothetical scenarios but take no action when given the same information about their own mayor. Partnering with the State Accounts Court of Pernambuco, we conducted a field experiment during the 2016 municipal elections in which the treatment group received information about official wrongdoing by their mayor. The treatment has no effect on self‐reported voting behavior after the election, yet when informing about malfeasance in the context of a vignette experiment, we are able to replicate the strong negative effect found in prior studies. We argue that voters' behavior in the abstract reflects the comparatively strong norm against corruption in Brazil. Yet on Election Day, their behavior is constrained by factors such as attitudes toward local political dynasties and the greater salience of more pressing concerns like employment and health services.     

Non‐Governmental Monitoring of Local Governments Increases Compliance with Central Mandates: A National‐Scale Field Experiment in China

Central governments face compliance problems when they rely on local governments to implement policy. In authoritarian political systems, these challenges are pronounced because local governments do not face citizens at the polls. In a national‐scale, randomized field experiment in China, we test whether a public, non‐governmental rating of municipal governments' compliance with central mandates to disclose information about the management of pollution increased compliance. We find significant and positive treatment effects on compliance after only one year that persist with reinforcement into a second post‐treatment year. The public rating appears to decrease the costs of monitoring compliance for the central government without increasing public and media attention to pollution, highlighting when this mode of governance is likely to emerge. These results reveal important roles that nonstate actors can play in enhancing the accountability of local governments in authoritarian political systems.
