A Brief Computer-Based Sexual Assault Risk Reduction Program: A Feasibility, Acceptability, and Preliminary Efficacy Pilot Study.

Sexual victimization among college women is a common problem, necessitating the development of risk reduction programs that are both effective and acceptable to this population. Computer-based programs may be a cost- and time-effective option. This pilot study sought to examine the feasibility, acceptability, and preliminary efficacy of a computer-based risk reduction program. A total of 136 collegiate women were randomly assigned to receive either a computer-based risk reduction program or an educational program about campus resources (active control condition). Measures included predicted use of resistance techniques, risk detection, and acceptability of the program. No participants dropped out of the study, and acceptability ratings were generally high. Women reported learning new material from the program, preferring the computer-based program to large-group programs, and believing that other undergraduate women would benefit from the program. Furthermore, women reported they did not experience significant emotional disturbance due to the material. In addition, postintervention, the risk reduction program group had significantly better risk detection compared with the control group. The control group evidenced a reduction in predicted use of assertive resistance between pre- and postintervention assessments, while the risk reduction program group did not. Given preliminary support for the feasibility, acceptability, and preliminary efficacy of a brief, computerized risk reduction program, further research on computerized, online risk reduction programs, such as the one in this study, appears warranted.

Social anxiety and resistance techniques in risky sexual scenarios: A possible mechanism of increased risk of victimization

Victims of sexual assault are never to blame, but increasing a woman's ability to effectively defend against unwanted sexual advances may help reduce risk of sexual victimization. This two-part study sought to examine social interaction anxiety as a risk factor of sexual victimization. A total of 1095 undergraduate females completed an online survey to assess social anxiety and other variables, of whom a subsample (n=136) completed the subsequent in-lab study in which predicted use of resistance techniques in a risky sexual situation was assessed. Controlling for past victimization, social interaction anxiety did not predict use of assertive or polite resistance techniques but did predict passive responding at the lowest two levels of sexual coercion in a series of three escalating sexual advances (i.e., breast fondling, genital fondling, and rape threat) in a story depicting a risky sexual situation. Overall, findings suggest that social anxiety may increase college women's risk of sexual victimization by increasing passivity during risky sexual situations, which has implications for risk reduction programs and for psychotherapy with women who present with high social anxiety.

Recent developments in the chemistry of solutions of salts in liquid alkali metals

Essential features of phase equilibria between alkali metal-salt-nonmetal are summarized and narrowed to detailed consideration of dilute solutions of salts in metals. The use of resistivity techniques is illustrated to determine nonmetal solubilities and hence derive partial molar quantities and anion solvation enthalpies. Dissolved nonmetals increase the resistivity of a specific metal by a characteristic amount and this property is exploited in the study of solute-solute interactions. Examples are given of solute association, dissociation and equilibrium in metallic solution and the reactions are correlated with the corresponding solid state reaction enthalpies.

The Use of Resistivity Techniques to Delineate Acid Mine Drainage in Ground Water

ABSTRACTA resistivity survey was run in an area of good geologic control to determine if resistivity is a viable technique for delineating aquifers contaminated with acid mine drainage. Results show that due to the high conductivity of the acid water, it makes an excellent target to define electrically. Aquifers polluted in this fashion were traced from their surface expression back under clays, shales, and coal toward the point of origin. Based on these results along with chemical analysis of streams and ground‐water samples, techniques are presented for the periodic monitoring of the ground water through surface resistivity techniques to determine both the extent and degree of contamination.
