    Notes: Abstract The olefin metathesis reaction was explored as a novel method to produce cross-linked silicone polymers. Although this reaction is well-known for non-silicone-containing monomers, there are no examples of this reaction in the presence of siloxanes. We have discovered a catalyst system for the reaction of silicone substrates comprised of a 1:4 molar ratio of WCl6/Sn(CH3)4. No metathesis is seen with the traditional ratio of catalyst and cocatalyst. In a model system, 1-hexenylmethylbis(trimethylsiloxy)silane underwent self-metathesis in greater than 75% yield. The catalyst system also promoted metathesis of a hexenyl containing silicone polymer.

    Notes: Abstract This three-wave study explored the prospective effects of habit (previous condom use), intentions to use condoms, past and proximal (before sex) drug use (alcohol, marijuana, cigarette, and hard drug use), and interactions among these variables on condom use among 211 men and women intravenous drug users. Several theoretical alternatives were evaluated. In one alternative, habit is thought to have preeminence over intentions and other variables in the prediction of behavior. In another alternative, drug use is thought to interact in its effects on condom use, by making individuals susceptible to not adhering to their previous intentions regarding safe sex practices. The results showed that condom use habit was a consistent and strong predictor of future condom use, whereas intention was a weak and inconsistent predictor. Neither past (long-term) nor proximal (before sex) drug use moderated (interacted with) the effects of either intention or habit on later condom use. The preeminence of habit in the prediction of condom use is similar to findings from other areas of health behavior, underscoring the need for more focused research on the underpinnings of health habit effects.
