Principles and performance of an electron spin echo spectrometer using far infrared lasers as excitation sources.

We have built an electron spin echo spectrometer operating at 604 GHz, extending the frequency limit of existing spectrometers by more than a factor of 4. In order to handle this high frequency we have used optical techniques, i.e., molecular gas lasers for the excitation pulses and far infrared techniques for the heterodyne detection system. The different components of the spectrometer are described in detail and first experimental results are given.

Independent living skills and posttraumatic stress disorder in women who are homeless: implications for future practice.

OBJECTIVE: Service delivery through community-based programs is the future of occupational therapy. This study examined independent living skills, traumatic experiences, and symptoms of Posttraumatic Stress Disorder (PTSD) in a sample of women residing in a supportive housing program for women and families who are homeless in order to determine the needs of this population and the possible role of occupational therapy in such a community-based program. METHOD: Twenty-four women residing in a supportive housing shelter in Kansas City, Missouri, volunteered to participate in this study. The participants were evaluated for independent living skills with the Kohlman Evaluation of Living Skills. A structured interview format was used to determine whether participants experienced a trauma and whether they met diagnostic criteria for PTSD. RESULTS: Results indicated that women who are homeless have deficits in independent living skills, especially in the area of money management. Results also indicated that traumatic experiences and PTSD are more prevalent among women who are homeless than among women in the general population. The relationship between independent living skills and PTSD among women who are homeless was not made clear by this study. CONCLUSION: The information gathered in this study underscores the importance of identifying and addressing occupational and mental health issues of women who are homeless. Results suggest that occupational therapists have a major role to play, evaluating and facilitating independent living skills, as members of multidisciplinary treatment teams in supportive housing programs for persons who are homeless.

The role of the church in adolescent drug education.

Despite drug education and prevention efforts, adolescent substance use is on the rise in the United States. In an exploration of correlates of substance use and components of effective drug education, three dimensions of religiosity--religious proscriptiveness, involvement in church activities, and the importance an individual places on church activities--emerge. Each has previously demonstrated an inverse relationship with adolescent substance use. In the present study, interactions among these three dimensions were evaluated in 238 adolescents. Religious proscriptiveness interacted with church involvement and with church importance in relation to adolescent use of alcohol, cigarettes, marijuana, and other drugs. Additionally, among adolescents who had ever used alcohol, a positive relationship was observed between religious proscriptiveness and binge drinking such that the highest incidence of binge drinking was reported by those affiliated with proscriptive religious groups. The church may be an important vehicle for drug education. Implications for drug education are discussed, and further research is suggested.
