CONTEXT More than 2 decades of conflict have led to widespread human suffering and population displacement in Afghanistan. In 2002, the Centers for Disease Control and Prevention and other collaborating partners performed a national population-based mental health survey in Afghanistan. OBJECTIVE To provide national estimates of mental health status of the(More)
The purpose of this study was to assess the roles of oral language and phonological awareness on reading performance in grade 3 bilingual students. Several hierarchical models assessed the best predictors of third grade English and Spanish word attack, word identification and reading comprehension. Predictor variables were measures of phonological(More)
Geographic information systems (GIS), global positioning systems and remote sensing have been increasingly used in public health settings since the 1990s, but application of these methods in humanitarian emergencies has been less documented. Recent areas of application of GIS methods in humanitarian emergencies include hazard, vulnerability, and risk(More)
We present a new approach to quasi text-independent speaker verification based on pattern matching. Our method first seeks phonetically matched segments in two speech signals. For all aligned frame pairs of these segments we compute the probability that they were uttered by the same speaker. Based on these frame-level probabilities we take the decision(More)
BACKGROUND To assess the effectiveness of the cholera prevention activities of the Peruvian Ministry of Health, we conducted a knowledge, attitudes, and practices (KAP) survey in urban and rural Amazon communities during the cholera epidemic in 1991. METHODS We surveyed heads of 67 urban and 61 rural households to determine diarrhoea rates, sources of(More)
AIMS Use of inotropic agents in patients with heart failure (HF) has been limited by adverse effects on outcomes. However, administration of positive inotropes at lower doses and concomitant treatment with beta-blockers might increase benefit-risk ratio. We investigated the effects of low doses of the positive inotrope enoximone on symptoms, exercise(More)
This paper deals with the problem of finding the optimal sequence of sub-word unit HMMs for a number of given utterances of a word. For this problem we present a new solution based on an extension of the Viterbi algorithm which maximizes the joint probability of the utterances and all possible sequences of sub-word units and hence guarantees to find the(More)
Marihuana or placebo cigarettes were smoked by 12 subjects in two environments, one "favorable" and one "neutral". The object was to determine the contribution of setting to the effects reported from the drug. Two quantifiable self-report measurements, the linear euphoriant scale and the card-sort version of the Addiction Research Center Inventory(More)
