1. Sunk Costs: does group decision make a difference?
Resumo Objetivo: Investigar se a tomada de decisão em conjunto é distinta da tomada de decisão individual quando se trata do viés custos afundados. Metodologia: Foram aplicados 96 questionários contendo 5 questões adaptadas de Arkes e Blumer (1985) com alunos de graduação. Os indivíduos foram considerados no modo indivídual, em duplas e em trios,

2. Estudos de simetria na associação genética usando dados de trios / Symmetry studies in the genetic association using data from trios
O grande desafio da Epidemiologia Genética, atualmente, é identificar, em um espaço de variáveis preditoras de alta dimensão e esparso, fatores de risco genéticos para doenças complexas. Um delineamento amostral útil nestes estudos é coletar dados de trios, que são pequenos núcleos familiares (pai e mãe, livres da doença, e filho afetado) e, em

3. A Transmission/Disequilibrium Test That Allows for Genotyping Errors in the Analysis of Single-Nucleotide Polymorphism Data
The present study assesses the effects of genotyping errors on the type I error rate of a particular transmission/disequilibrium test (TDTstd), which assumes that data are errorless, and introduces a new transmission/disequilibrium test (TDTae) that allows for random genotyping errors. We evaluate the type I error rate and power of the TDTae under a variety

4. Relationship Inference from Trios of Individuals, in the Presence of Typing Error
Misspecification of relationships and of genotype data can cause problems in linkage analyses based on genome-scan data. Previous reports have focused on pairwise relationships and a simple error model. This article considers the increased information available from the joint analysis of trios of individuals, integrating this analysis with an error model tha

5. Haplotype and Missing Data Inference in Nuclear Families
Determining linkage phase from population samples with statistical methods is accurate only within regions of high linkage disequilibrium (LD). Yet, affected individuals in a genetic mapping study, including those involving cases and controls, may share sequences identical-by-descent stretching on the order of 10s to 100s of kilobases, quite possibly over re

6. Complex social structure, alliance stability and mating access in a bottlenose dolphin 'super-alliance'.
Large brain size in mammals has been related to the number and complexity of social relationships, particularly social alliances within groups. The largest within-group male alliance known outside of humans is found in a social network (> 400) of Indian Ocean bottlenose dolphins (Tursiops aduncus) in Shark Bay Western Australia. Members of this dolphin 'supe

7. Family-Based Analysis Using a Dense Single-Nucleotide Polymorphism–Based Map Defines Genetic Variation at PSORS1, the Major Psoriasis-Susceptibility Locus
Psoriasis is a common skin disorder of multifactorial origin. Genomewide scans for disease susceptibility have repeatedly demonstrated the existence of a major locus, PSORS1 (psoriasis susceptibility 1), contained within the major histocompatibility complex (MHC), on chromosome 6p21. Subsequent refinement studies have highlighted linkage disequilibrium (LD)

8. Effect of COMT Val108/158 Met genotype on frontal lobe function and risk for schizophrenia
Abnormalities of prefrontal cortical function are prominent features of schizophrenia and have been associated with genetic risk, suggesting that susceptibility genes for schizophrenia may impact on the molecular mechanisms of prefrontal function. A potential susceptibility mechanism involves regulation of prefrontal dopamine, which modulates the respon
