1. NATURAL LANGUAGE AT A CROSSROADS: FORMAL AND PROBABILISTIC APPROACHES IN PHILOSOPHY AND COMPUTER SCIENCE
Abstract Philosophy of language and computer science, despite being very distinct fields, share a great interest in natural language. However, while philosophy has traditionally opted for a formalist approach, computer science has been increasingly favoring probabilistic models. After presenting these two approaches in more detail, we discuss some of their m

2. Diametric distribution modeling of forest species in arboreal Caatinga vegetation, Brazil
ABSTRACT The distribution modeling in diameter classes is an important indicator of the potential use of a forest community, as well as the projection of future forest production. The objective of this study was to evaluate the diametric structure and to select probabilistic density functions for three woody species in forested arboreal Caatinga vegetation i

3. Structural reliability model considering mixed probabilistic and interval variables
Abstract Traditional probability-based structural reliability analysis method can only consider random uncertainties described by random distribution functions, which required sufficient experimental samples. On comparison, interval uncertainties can be more appropriate when lacking information. In realistic situations, several structural reliability models

4. Estimativa da resistência característica à tração da madeira na direção paralela às fibras por meio de modelos probabilísticos
RESUMO Para um dimensionamento de estruturas de madeiras dentro das exigências de segurança, a resistência para determinada solicitação mecânica é calculada com base em seu valor característico, correspondente ao percentil de 5% de um determinado modelo de distribuição de probabilidades. A norma brasileira NBR 7190 [1] estabelece, para pequenas amo

5. Sensitivity and Specificity of Cephalometric Measures for the Diagnosis of Sagittal Skeletal Malocclusion
Abstract Objective: To evaluate and compare sensitivity and specificity of ANB, Wits, APDI and AF-BF to diagnose sagittal skeletal malocclusions, in children between 6 to 12 years old, using ROC curves, a widely accepted method for the analysis and evaluation of diagnostic tests. Material and Methods: A descriptive-comparative study of diagnostic tests was

6. Carga do tabagismo no Brasil e benefício potencial do aumento de impostos sobre os cigarros para a economia e para a redução de mortes e adoecimento
A prevalência do tabagismo no Brasil reduziu sobremaneira nas últimas décadas, mas o país ainda tem uma elevada carga de doença associada a este fator de risco. O objetivo deste trabalho foi estimar a carga de mortalidade, morbidade e custos para a sociedade associada ao tabagismo em 2015 e o potencial impacto gerado em desfechos de saúde e para a econ

7. Manutenção do trabalho e presença de condições crônicas em idosos comunitários: evidências da Rede Fibra-BH
Resumo Este estudo transversal foi conduzido em uma amostra probabilística de 597 idosos comunitários residentes em Belo Horizonte, com o objetivo de avaliar quais condições crônicas apresentam associações independentes com a permanência do idoso no mercado de trabalho, a fim de verificar a influência de cada uma isoladamente. A análise multivariad

8. Relationship Between The Organizational Memory and Innovativity: The Case of Software Development Companies in The Southern Region of Brazil
ABSTRACT This paper focuses on the relationship between the Organizational Memory (OM) and Organizational Innovation (OI) practices of Software Developers. This industry is meaningful for the economy and has significant transversality of performance; at the same time, it is highly dynamic and inventive. These traits corroborate our research choice around OM

10. PERIODIC REVIEW SYSTEM FOR INVENTORY REPLENISHMENT CONTROL FOR A TWO-ECHELON LOGISTICS NETWORK UNDER DEMAND UNCERTAINTY: A TWO-STAGE STOCHASTIC PROGRAMING APPROACH
ABSTRACT Here, we propose a novel methodology for replenishment and control systems for inventories of two-echelon logistics networks using a two-stage stochastic programming, considering periodic review and uncertain demands. In addition, to achieve better customer services, we introduce a variable rationing rule to address quantities of the item in short.

11. Modeling Bayesian Networks from a conceptual framework for occupational risk analysis
Abstract Occupational risk is the possibility that some element included in a particular work environment can cause damage to someone’s health. Thereby, the risk is understood as the product of probability and consequences. In this sense, risk analysis through probabilistic stochastic techniques, such as Bayesian networks (BN), becomes an important tool to

12. Maternal recognition of child mental health problems in two Brazilian cities
Objective: To identify child behaviors and types of impairment that increase the likelihood of maternal recognition of emotional/behavioral problems (EBP) in children and adolescents. Methods: Maternal-reported data were obtained from two subsamples of 11-to-16-year-olds derived from cross-sectional studies conducted in two Brazilian municipalities: Itabor
