Traditional crash count models, such as the Poisson and Negative Binomial models, do not account for the temporal correlation of crash data. In reality, crashes that occur in close proximity in time are likely to share unobserved effects which may have been excluded from the model. If the temporal correlation of crash data is ignored, the estimated parameters could be less precise and biased. T...

PURPOSE Cognitive deficits are common in the first episode of psychosis (FEP) and may begin much earlier. While some evidence suggests that the decline in cognition occurs over the untreated symptomatic period, including the prodromal phase, others point to these deficits being present even earlier. We aimed to investigate the differential effect of untreated symptomatic and pre-morbid phases o...

OBJECTIVES To understand alcohol use trends and alcohol-related harm among youth in South Africa (SA) between 1998 and 2008, and discuss implications for the current alcohol policy process. METHODS A review was conducted of 4 national prevalence and 2 sentinel surveillance studies. Data were extracted to Epi Info (version 7) and chi-square analyses undertaken. RESULTS. Lifetime alcohol use re...

Abstract This paper involved a cross-sectional study that evaluated the results and refusals to take the breathalyzer test among drivers intercepted by the Driving Under the Influence (DUI) Spot-Check Campaign (Operação Lei Seca) in the capital of Rio de Janeiro and Baixada Fluminense. It was conducted using data provided by the State Government which were collected from drivers intercepted in ...

In Mytilus, females carry predominantly maternal mitochondrial DNA (mtDNA) but males carry maternal mtDNA in their somatic tissues and paternal mtDNA in their gonads. This phenomenon, known as doubly uniparental inheritance (DUI) of mtDNA, presents a major departure from the uniparental transmission of organelle genomes. Eggs of Mytilus edulis from females that produce exclusively daughters and...

INTRODUCTION To date, few studies have focused on the characterization of clinical phenomenology regarding gender in population at high-risk of psychosis. This paper is an attempt to summarize the findings found in the scientific literature regarding gender differences in high-risk populations, taking into account parameters studied in populations with schizophrenia and other psychotic disorder...

and Applied Analysis 3 2. Existence and Uniqueness In this section, the existence and uniqueness of the minimizer for the model 1.4 are proved. Some basic notations and properties concerning with the BV 2 space can be seen in 8, 13 . Motivated by 5 , we have the following existence and uniqueness result for the optimization problem 1.4 . Theorem 2.1. Assume Ω is an open, bounded Lipschitz domai...
