Psychosocial Characteristics and Sexual Behaviors of People in Care for HIV Infection: An Examination of Men Who Have Sex with Men, Heterosexual Men and Women

Few studies have examined the psychosocial factors associated with sexual transmission behaviors among HIV-positive men who have sex with men (MSM), heterosexual men (MSW) and women. We enrolled 1,050 sexually active HIV-positive patients at seven HIV clinics in six US cities as part of a clinic-based behavioral intervention. We describe the sexual transmission behaviors and examine demographic, clinical, psychosocial, and clinic prevention variables associated with unprotected anal or vaginal intercourse (UAVI). Twenty-three percent of MSM, 12.3% of MSW and 27.8% of women engaged in UAVI with partners perceived to be HIV-negative or of unknown serostatus. Among MSM and MSW, having multiple partners and lower self-efficacy were associated with increased odds of UAVI. Self-rating one’s health status as excellent/very good was a risk factor for UAVI among MSM. Among women, binge drinking and stressful life events were associated with UAVI. These findings identify variables that warrant attention in targeted interventions

Scan alignment and 3d surface modeling with a helicopter platform

This paper describes initial results for a laser-based aerial mapping system. Our approach applies a real-time laser scan matching algorithm to 2-D range data acquired by a remotely controlled helicopter. Results obtain for urban and natural terrain exhibit an unprecedented level of spatial detail in the resulting 3-D maps.
