Population genetics of nine STR loci in two populations from Brazil

The Short Tandem Repeats (STRs) D3S1358, HUMvWA31/A, HUMFIBRA/FGA, D8S 1179, D2S11, D18S51, D5S818, D13S317, and D7S820 were studied in two Brazilian populations (from Amazonia and S. Paulo) using the "AmpF1 STR Profiler Plus PCR Amplification Kit." The nine loci showed a combined discrimination power greater than 0.9999999999 and a chance of exclusion of 0.9999.     

Eight short tandem repeats (STR) frequencies for descendants from Terena indigenous Brazilian group

POPULATION: descendants from Terenas an indigenous group.     

Allele frequencies data and statistic parameters for 16 STR loci-D19S433, D2S1338, CSF1PO, D16S539, D7S820, D21S11, D18S51, D13S317, D5S818, FGA, Penta E, TH01, vWA, D8S1179, TPOX, D3S1358-in the Rio de Janeiro population, Brazil

Allele frequencies for 16 short tandem repeats (STR) loci were determined with a sample of 230-300 unrelated individuals from the population of Rio de Janeiro, Brazil. The loci are the most commonly used in forensic and paternity testing, being analysed by the Identifiler (Applied Biosystems) and PowerPlex 2.1 (Promega) commercial kits. It was proved that Penta E and D18S51 are the most polymorphic loci.     

Early maladaptive schemas in convicted sexual offenders: Preliminary findings

Core cognitive schemas may play a role in the vulnerability for sexual offending. Identifying these schemas could help to conceptualize sexual crimes and rehabilitate convicted sexual offenders. The aim of this preliminary study was to explore the relationship between early maladaptive schemas (EMSs) and sexual offending, as well as how rapists and child sex molesters differ in terms of these schemas. Thirty-two men convicted for rape, 33 convicted for child sexual abuse, and 30 non-offenders were evaluated using the Young Schema Questionnaire (YSQ-S3) and the Brief Symptom Inventory (BSI). Results showed that participants convicted for child sexual abuse presented significantly more schemas from the disconnection/rejection, impaired autonomy/performance, other directness, and over vigilance/inhibition domains than non-offenders, whereas rapists presented more schemas from the impaired autonomy/performance domain than non-offenders. Differences between sex offenders showed that child molesters presented more schemas of pessimism than rapists. Preliminary findings suggested that EMSs may impact sex offender's perceptions about themselves and about the world. Schema-focused therapy (Young, 1990, 1999) may thus be an acceptable approach to sex offender's psychological assessment and intervention.     

BELT AND ROAD UNITES CHINA AND LATIN AMERICA

The Belt and Road Initiative, proposed in 2013 by Chinese President Xi Jinping, improves cooperation among its participants in terms of both economic and cultural? devel-opment. Latin American countries started to join the initiative in 2017, and as of 2019, 19 of them signed related memoranda of understand-ing with China.     

A study on ten short tandem repeat systems: African immigrant and Spanish population data

This work presents the results obtained from a genetic–population study for the D1S1656 system in the population of Southwest Spain (Huelva, Cádiz and Sevilla), Spaniards of Caucasian origin from North Africa (Ceuta), as well as in the black Central West African and Moroccan immigrant populations in Spain. The results of a study of the autochtonous population of the Canary Islands (n=138), and immigrant Central West African populations in Spain (n=132), obtained for nine short tandem repeat (STR) loci (D3S1358, VWA, FGA, D8S1179, D21S11, D18S51, D5S818, D13S317, D7S820), as well as the amelogenin locus, all contained in Profiler Plus™ (Perkin-Elmer) PCR amplification kits, are also presented. Except for the FGA and VWA data on immigrant Central West African populations in Spain, no deviations from the Hardy–Weinberg equilibrium were detected.     

The color of child mortality in Brazil, 1950-2000: social progress and persistent racial inequality

Now that racism has been officially recognized in Brazil, and some universities have adopted affirmative-action admission policies, measures of the magnitude of racial inequality and analyses that identify the factors associated with changes in racial disparities over time assume particular relevance to the conduct of public debate. This study uses census data from 1950 to 2000 to estimate the probability of death in the early years of life, a robust indicator of the standard of living among the white and Afro-Brazilian populations. Associated estimates of the average number of years of life expectancy at birth show that the 6.6-year advantage that the white population enjoyed in the 1950s remained virtually unchanged throughout the second half of the twentieth century, despite the significant improvements that accrued to both racial groups. The application of multivariate techniques to samples selected from the 1960, 1980, and 2000 census enumerations further shows that, controlling for key determinants of child survival, the white mortality advantage persisted and even increased somewhat in 2000. The article discusses evidence of continued racial inequality during an era of deep transformation in social structure, with reference to the challenges of skin color classification in a multiracial society and the evolution of debates about color, class, and discrimination in Brazil.     

Genetic study of 15 STRs loci of Identifiler system in Angola population

Angola is located in the African continent, in the area of southern Africa and has a population of approximately 14 million inhabitants. The Angola population has origin from Occidental and Southern Bantu people that came from the great lakes region, creating the most ever known African migration of our days.Allele frequencies for the 15 STRs loci in the AmpFlSTR Identifiler kit (D8S1179, D21S11, D7S820, CSF1PO, D3S1358, HUMTH01, D13S317, D16S539, D2S1338, D19S433, HUMVWA, TPOX, D18S51, D5S818, HUMFIBRA/FGA and including the segment of the X-Y homologous gene amelogenin) were studied for Angola population.The genotype frequency of the 15 STR loci showed no significant deviations from Hardy–Weinberg equilibrium expectations and great values for the combined power of discrimination and combined power of a priori exclusion validate the application of these markers in forensic genetics. Comparative analyses between Angola population data and other relevant population database from Africa, Europe and American are presented.
