There are a number of opportunities for public policy to help microenterprise programs support emerging entrepreneurs as they contend with the current economic environment.Small business ; Public policy

Fuels and chemicals from biomass using solar thermal energy

The significant nearer term opportunities for the application of solar thermal energy to the manufacture of fuels and chemicals from biomass are summarized, with some comments on resource availability, market potential and economics. Consideration is given to the production of furfural from agricultural residues, and the role of furfural and its derivatives as a replacement for petrochemicals in the plastics industry

The free path in a high velocity random flight process associated to a Lorentz gas in an external field

We investigate the asymptotic behavior of the free path of a variable density random flight model in an external field as the initial velocity of the particle goes to infinity. The random flight models we study arise naturally as the Boltzmann-Grad limit of a random Lorentz gas in the presence of an external field. By analyzing the time duration of the free path, we obtain exact forms for the asymptotic mean and variance of the free path in terms of the external field and the density of scatterers. As a consequence, we obtain a diffusion approximation for the joint process of the particle observed at reflection times and the amount of time spent in free flight.Comment: 30 page

Group Versus Individual Therapy in Adolescent Substance Abuse Treatment: Finding Interventions that Work

This study explored the effectiveness of individual therapy versus group therapy in the treatment of adolescents in an outpatient substance abuse treatment clinic. Chart review was used to collect information from adolescent male and female clients. Independent samples t-tests, chi-square analyses, and ANOVA tests were used to determine the relationship between interventions and success in treatment. Clients receiving individual therapy only in both The Seven Challenges program and the eclectic counseling category had greater decreases in substance use and had more successful discharges in fewer overall treatment sessions. There is need for further research with a larger sample size to confirm the findings
