BACKGROUND This study presents estimates of lifetime and 12-month prevalence of 14 DSM-III-R psychiatric disorders from the National Comorbidity Survey, the first survey to administer a structured psychiatric interview to a national probability sample in the United States. METHODS The DSM-III-R psychiatric disorders among persons aged 15 to 54 years in(More)
BACKGROUND Data were obtained on the general population epidemiology of DSM-III-R posttraumatic stress disorder (PTSD), including information on estimated life-time prevalence, the kinds of traumas most often associated with PTSD, sociodemographic correlates, the comorbidity of PTSD with other lifetime psychiatric disorders, and the duration of an index(More)
OBJECTIVES This study examined the risk of psychiatric disorders among individuals with same-sex sexual partners. METHODS Data are from the National Comorbidity Survey, a nationally representative household survey. Respondents were asked the number of women and men with whom they had sexual intercourse in the past 5 years. Psychiatric disorders according(More)
Data from a nationally representative sample of the general population are used to study cohort differences in the prevalence of DSM-III-R Major Depressive Episode (MDE). We document increasing lifetime prevalence of MDE among both men and women in more recent cohorts, but no major change in the sex ratio over the 40-year period retrospectively covered in(More)
OBJECTIVES To analyze nationally representative data on the lifetime and 12-month prevalences of use of and dependence on illegal drugs (marijuana/hashish, cocaine/crack, heroin, hallucinogens), nonmedical prescription psychotropic drugs (sedatives, tranquilizers, stimulants, analgesics), and inhalants; and to examine data on the sociodemographic correlates(More)
We perform a series of 3-class sentiment classification experiments on a set of 2,624 tweets produced during the run-up to the Irish General Elections in February 2011. Even though tweets that have been labelled as sarcastic have been omitted from this set, it still represents a difficult test set and the highest accuracy we achieve is 61.6% using(More)
The SenseCam is a passive capture wearable camera and when worn continuously it takes an average of 1,900 images per day. It can be used to create a personal lifelog or visual recording of a wearer's life which can be helpful as an aid to human memory. For such a large amount of visual information to be useful, it needs to be structured into "events", which(More)
BACKGROUND beta-glucosidases occur in a variety of organisms and catalyze the hydrolysis of aryl and alkyl-beta-D-glucosides as well as glucosides with only a carbohydrate moiety (such as cellobiose). The cyanogenic beta-glucosidase from white clover (subsequently referred to as CBG) is responsible for the cleavage of cyanoglucosides. Both CBG and the(More)
AMA-1 of Plasmodium falciparum is a promising candidate antigen in malaria vaccine development. In this study, we have mapped the immunodominant T-cell determinants in this antigen by using synthetic peptides. From the amphipathic scores, 17 putative T-cell determinants were identified. Nine of the 17 peptides complementary to the putative T-cell(More)
BACKGROUND Idiopathic intracranial hypertension (IIH) has an estimated incidence of one to three people per 100,000 people per year, and occurs most commonly in obese, young women. IIH is associated with severe morbidity, notably due to a significant threat to sight and severe headache. Several different management options have been proposed. Conservative(More)
