1. Informational content of key audit matters and financial analysts’ forecasts
Resumo O objetivo deste artigo foi analisar a relação entre o conteúdo informacional dos principais assuntos de auditoria (PAA) reportados no Relatório de Auditoria Independente (RAI) e a previsão de analistas financeiros das empresas listadas na B3 S.A. - Brasil, Bolsa, Balcão (B3). As pesquisas que investigaram a relevância dos PAA não analisaram a

2. A new model for describing remission times: the generalized beta-generated Lindley distribution
New generators are required to define wider distributions for modeling real data in survival analysis. To that end we introduce the four-parameter generalized beta-generated Lindley distribution. It has explicit expressions for the ordinary and incomplete moments, mean deviations, generating and quantile functions. We propose a maximum likelihood procedure t

3. Fatores de influência no preço do milho no Brasil
Compreender a dinâmica de funcionamento do mercado de milho brasileiro, procedendo a uma investigação dos fatores que afetam as quantidades e preços nesse mercado, é o objetivo deste trabalho. Os testes de raiz unitária foram feitos utilizando-se a metodologia DF-GLS - Dickey Fuller Generalized Least Square - e os de cointegração de Johansen (1988).

5. A structure-preserving iteration method of model updating based on matrix approximation theory
Some theories and a method are discussed on updating a generalized centrosymmetric model. It gives a generalized centrosymmetric modified solution with partial prescribed least square spectra constraints. The emphasis is given on exploiting structure-preserving algorithm based on matrix approximation theory. A perturbation theory for the modified solution is

6. Identification of non-newtonian rheological parameter through an inverse formulation
In this work, we introduce an inverse formulation to be applied in the identification of a rheological parameter associated to non-Newtonian fluids. It is built upon a creeping flow through a 4 to 1 axisymmetric abrupt contraction. The fluid is modeled by the Generalized Newtonian Fluid constitutive equation. The viscosity function is based on the one propos

7. Prediction of hybrid means from a partial circulant diallel table using the ordinary least square and the mixed model methods
By definition, the genetic effects obtained from a circulant diallel table are random. However, because of the methods of analysis, those effects have been considered as fixed. Two different statistical approaches were applied. One assumed the model to be fixed and obtained solutions through the ordinary least square (OLS) method. The other assumed a mixed m

8. Microsatellites Are Molecular Clocks That Support Accurate Inferences about History
Microsatellite length mutations are often modeled using the generalized stepwise mutation process, which is a type of random walk. If this model is sufficiently accurate, one can estimate the coalescence time between alleles of a locus after a mathematical transformation of the allele lengths. When large-scale microsatellite genotyping first became possible,
