Mitochondrial DNA control region polymorphism in the population of Alagoas state, north-eastern Brazil

The sequences of the two hypervariable (HV) segments of the mitochondrial DNA (mtDNA) control region were determined in 167 randomly selected, unrelated individuals living in the state of Alagoas, north-eastern Brazil. One hundred and forty-five different haplotypes, associated with 139 variable positions, were determined. More than 95% of the mtDNA sequences could be allocated to specific mtDNA haplogroups according to the mutational motifs. Length heteroplasmy in the C-stretch HV1 and HV2 regions was observed in 22 and 11%, respectively, of the population sample. The genetic diversity was estimated to be 0.9975 and the probability of two random individuals presenting identical mtDNA haplotypes was 0.0084. The most frequent haplotype was shared by six individuals. All sequences showed high-quality values and phantom mutations were not detected. The diversity revealed in the mitochondrial control region indicates the importance of this locus for forensic casework and population studies within Alagoas, Brazil.     

Regulating lobbying through voluntary transparency clubs: The connoisseurs’ assessment. Evidence from the European Union

Regulating private actors’ participation in policy‐making is key to democratic governance. Across political systems, targeted transparency is used to regulate lobbying activities. We examine the extent to which primary regulatory targets (organizations with frequent access to policy‐makers) support the architecture of lobbying regulation regimes set up as voluntary transparency clubs. Our empirical testing ground is the European Union. We conceptualize the EU Transparency Register as a Voluntary Transparency Club, elaborate on its club goods, and derive a set of theoretical expectations about its members’ evaluations of the club's transparency standards, membership size, and monitoring and enforcement mechanisms. We find significant differences between members’ and non‐members’ assessment regarding the regulatory performance of this transparency club. Members with frequent access to executive policy‐makers criticize the club's transparency standards and do not consider the Register a useful regulatory instrument. Yet, they support expanding its regulatory remit and increasing the club membership.     

Unveiling patterns of contestation over Better Regulation reforms in the European Union

Regulatory reforms labelled ‘Better Regulation’ are a prominent item on the political agendas of most advanced democracies and the European Union. Governments adopt Better Regulation measures to strengthen their democratic legitimacy and increase their regulatory and economic effectiveness. Notwithstanding their rhetorical appeal, their design and implementation are susceptible to high levels of political contestation. We therefore ask: are there systematic differences in stakeholders’ demands for what Better Regulation should achieve? What explains these differences? We argue that conflict over Better Regulation is rooted in what stakeholders prefer as a regulatory system of governance. Stakeholders demand reforms that lead to one of the following three scenarios: deregulation, technocratic or participatory policy‐making. We examine stakeholders’ demands expressed in the EU. We find that national authorities responsible for coordinating Better Regulation and cross‐sectoral business organizations support deregulatory and technocratic reforms. Business and public interest organizations are equally supportive of strengthening participatory policy‐making.     

Associations between Cultural Stressors,Cultural Values,and Latina/o College Students’ Mental Health

Latina/o college students experience cultural stressors that negatively impact their mental health, which places them at risk for academic problems. We explored whether cultural values buffer the negative effect of cultural stressors on mental health symptoms in a sample of 198 Latina/o college students (70?% female; 43?% first generation college students). Bivariate results revealed significant positive associations between cultural stressors (i.e., acculturative stress, discrimination) and mental health symptoms (i.e., anxiety, depressive, psychological stress), and negative associations between cultural values of familismo, respeto, and religiosity and mental health symptoms. Several cultural values moderated the influence of cultural stressors on mental health symptoms. The findings highlight the importance of helping Latina/o college students remain connected to their families and cultural values as a way of promoting their mental health.     

Heteroplasmy in hair: differences among hair and blood from the same individuals are still a matter of debate

The analysis of mitochondrial DNA (mtDNA) is a useful tool in forensic cases when sample contents too little or degraded nuclear DNA to genotype by autosomal short tandem repeat (STR) loci, but it is especially useful when the only forensic evidence is a hair shaft. Several authors have related differences in mtDNA from different tissues within the same individual, with high frequency of heteroplasmic variants in hair, as also in some other tissues. Is still a matter of debate how the differences influence the interpretation forensic protocols. One difference between two samples supposed to be originated from the same individual are related to an inconclusive result, but depending on the tissue and the position of the difference it should have a different interpretation, based on mutation-rate heterogeneity of mtDNA. In order to investigate it differences in the mtDNA control region from hair shafts and blood in our population, sequences from the hypervariable regions 1 and 2 (HV1 and HV2) from 100 Brazilian unrelated individuals were compared. The frequency of point heteroplasmy observed in hair was 10.5% by sequencing. Our study confirms the results related by other authors that concluded that small differences within tissues should be interpreted with caution especially when analyzing hair samples.
