1. Peritraumatic tonic immobility is associated with PTSD symptom severity in Brazilian police officers: a prospective study
Objective: Peritraumatic reactions feature prominently among the main predictors for development of posttraumatic stress disorder (PTSD). Peritraumatic tonic immobility (PTI), a less investigated but equally important type of peritraumatic response, has been recently attracting the attention of researchers and clinicians for its close association with traum

2. Modelo destrutivo com variável terminal em experimentos quimiopreventivos de tumores em animais
A indução química de substâncias cancerígenas em experimentos quimiopreventivos em animais é cada vez mais frequente em pesquisas biológicas. O objetivo destes experimentos biológicos é avaliar o efeito de um determinado tratamento na taxa de incidência de tumores em animais. Neste trabalho o número de tumores promovidos por animal será modelado

3. Distribuições em série de potências modificadas inflacionadas e distribuição Weibull binominal negativa / Inflated modified power serie distribution and Weibull negative binomial
In this paper, some result such as moments generating function, recurrence relations for moments and some theorems of the class of modified power series distributions (MPSD) proposed by Gupta (1974) and of the class of inflated modified power series distributions (IMPSD) both at a different point of zero as the zero point are presented. The standard Poisson

5. A STOCHASTIC MODEL FOR THE NUMBER OF TRANSACTIONS IN THE BRAZILIAN CAPITAL MARKET: WITH APPLICATION IN SIMULATING DAILY RETURNS OF STOCK IN THE FRAMEWORK OF A TIME DEFORMATION MODEL / UM MODELO ESTOCÁSTICO PARA O NÚMERO DE NEGÓCIOS COM AÇÕES DO MERCADO DE CAPITAIS BRASILEIRO: COM APLICAÇÃO EM SIMULAÇÃO DE RETORNOS DIÁRIOS ATRAVÉS DE DEFORMAÇÃO TEMPORAL
This thesis proposes a new stochastic model for the daily number of transactions with stocks in the Brazilian capital market. The model, which we call ZINB-HF (Zero ¿ Inflated Negative Binomial Harvey- Fernandes), is an extension of a local scale model for count data. In it, the daily number of transactions follows a serially correlated negative binomial di

6. The use of negative binomial modelling in a longitudinal study of gastrointestinal parasite burdens in Canadian dairy cows
The epidemiology of bovine gastrointestinal nematodes was investigated through a 1-year (October 1999 to September 2000) longitudinal study in 38 Canadian dairy herds from 4 different provinces (Prince Edward Island, Quebec, Ontario, Saskatchewan). For each herd, fecal egg counts from 8 randomly selected animals were performed on a monthly or quarterly basis
