Sexual activity and risk of HIV infection among patients with schizophrenia
Objective: This study sought to determine the frequency and types of sexual behavior among patients with schizophrenia and to assess the behavior with respector risk of HIV infection. Method: Ninety-five inpatients and outpatients with a research diagnosis of schizophrenia underwent a series of face-to-face interviews to determine their sexual activity and correlate it with demographic characteristics, psychopathology, and medication side effects. Results: Forty-four percent of the patients had been sexually active in the preceding 6 months, and 62% of these had had multiple partners. Sexual activity was associated with greater general psychopathology
A simple Stress Time Index (STI) for predicting yield loss in the tea crop due to drought is proposed, based on the daily summation of the difference between the potential soil water deficit and a specified limiting value. Validation of the technique with results from a line-source irrigation experiment with a single clone in the Southern Highlands of Tanzania suggests that there is a linear relationship between STI and relative yield loss during the warm dry season. As a result of changes in the composition of the shoot population at each harvest the apparent critical deficit at which shoot growth is restricted increases from below 20 to 300 mm as the dry season progresses. The rate of yield loss with increasing STI also varies through the dry season for the same reason.
