13. An ecological and comparative analysis of parasites in juvenile Mugil liza (Pisces, Mugilidae) from two sites in Samborombón bay, Argentina
ABSTRACT Mugil liza Valenciennes, 1836 is an economically important food fish and has been recommended for aquaculture in South America. A total of 278 fishes were collected in the spring and summer of 2009 and 2010. These fish were sorted into sample groups according to their size class. We used Bayesian statistics and 95% credible intervals for each parame

14. Spatial and spatiotemporal occurrence of human visceral leishmaniasis in Adamantina, State of São Paulo, Brazil
Abstract: INTRODUCTION : Several municipalities of the Western region of the State of São Paulo have been affected by human visceral leishmaniasis (HVL), including the City of Adamantina, where the first autochthonous cases occurred in 2004. Therefore, this study aimed to describe the spatial and spatiotemporal occurrence of HVL in Adamantina. METHODS : S

15. Daily counting of manufactured units sent for quality control: a bayesian approach
This paper presents the statistical modeling for daily counting statistics of units that arrive for quality inspection at a food company. Different Poisson regression models were considered in order to analyze the data collected, with a Bayesian focus. The main objective was to forecast the daily average count based on co-variables such as days of the week.

16. Relaciones entre los bovinos criollos panameños y algunas razas criollas de Latinoamérica
The objective of this work was to establish the genetic relationship between Guabalá and Guaymi cattle populations and some native ones of Latin America. Factorial correspondence analysis, analysis of molecular variance, genetic distances, average number of migrants per population and Wright's F statistics were performed. Population structure was assessed b

18. Diversidade genética da abelha Eufriesea violacea (Hymenoptera, Apidae, Euglossini)
In this study six populations of Eufriesea violacea had their genetic structure and diversity estimated using microsatellite markers and mitochondrial obtained by PCR-RFLP. The samplings of male bees were carried out in Atlantic Forest remnants located in the states of Paraná (PR1, PR2, and PR3), São Paulo (SP1), Santa Catarina (SC1) and Rio Grande do Sul

19. Genetic divergence of rubber tree estimated by multivariate techniques and microsatellite markers
Genetic diversity of 60 Hevea genotypes, consisting of Asiatic, Amazonian, African and IAC clones, and pertaining to the genetic breeding program of the Agronomic Institute (IAC), Brazil, was estimated. Analyses were based on phenotypic multivariate parameters and microsatellites. Five agronomic descriptors were employed in multivariate procedures, such as S

20. Bayesian analysis of 2k factorial designs using the sparse eects, hierarchy and heredity principles / Análise Bayesiana de ensaios fatoriais 2k usando os princípios dos efeitos esparsos, da hierarquia e da hereditariedade
No Planejamento de experimentos para o ajuste de modelos polinomiais envolvendo k fatores principais e respectivas interações, e bastante comum a utilização dos fatoriais 2k, 3k ou frações dos mesmos. Para as analises dos resultados desses experimentos, freqüentemente se considera o princípio da hereditariedade, ou seja, uma vez constatada uma intera

21. Bayesian inference in genetic parameter estimation of visual scores in Nellore beef-cattle
The aim of this study was to estimate the components of variance and genetic parameters for the visual scores which constitute the Morphological Evaluation System (MES), such as body structure (S), precocity (P) and musculature (M) in Nellore beef-cattle at the weaning and yearling stages, by using threshold Bayesian models. The information used for this was

22. Um modelo espaço-temporal bayesiano para medir a interação social na criminalidade : simulações e evidências na Região Metropolitana de São Paulo
Neste trabalho utilizamos um modelo espaço-temporal proposto em Rojas (2004) para medir a interação social da criminalidade na região metropolitana de São Paulo. Realizamos simulações de Monte Carlo para testar a capacidade de estimação do modelo em diferentes cenários. Observamos que a estimação melhora com o aumento de observações ao longo do

23. Diagramas de influência e teoria estatística / Influence Diagrams and Statistical Theory
The main objective of this work is to analyze the controversial concept of information in Statistics. To do so, firstly the concept of information according to Basu is presented. Next, the analysis is divided in three parts: information in a data set, information in an experiment and influence diagrams. In the first two parts, we always tried to define prope

24. The use of Monte Carlo simulation via Markov chains in genetic breeding / O uso de simulação de Monte Carlo via cadeias de Markov no melhoramento genético
Este trabalho teve por objetivo fornecer um referencial teórico e aplicado sobre os principais métodos de simulação de Monte Carlo via cadeias de Markov (MCMC), buscando dar ênfase em aplicações no melhoramento genético. Assim, apresentaram-se os algoritmos de Metropolis-Hastings, simulated annealing e amostrador de Gibbs. Os aspectos teóricos dos m
