Abstract In this paper, we examine the antecedents and consequences of timing in the transition from high school to college. Using the National Education Longitudinal Study of 1988 (NELS:88), we find that 16 percent of high school graduates postpone enrollment by seven months or more after completing high school. Delayers tend to have some common characteristics: they come from families with fe...

The dairy industry is one of the largest global producers wastewater and generates huge volumes processing sludge (DPS). There are two main types DPS, lime-treated dissolved air floatation bio-chemically-treated activated sludge. These may also be converted to STRUBIAS (STRUvite, BIochar, AShes) products which have potential as fertilizers, secondary feedstocks for phosphate fertiliser granules...

In 2008, this group published a paper on approaches for two-stage crossover bioequivalence (BE) studies that allowed for the reestimation of the second-stage sample size based on the variance estimated from the first-stage results. The sequential methods considered used an assumed GMR of 0.95 as part of the method for determining power and sample size. This note adds results for an assumed GMR ...

We estimate the post-release economic effects of participation in prison-based General Educational Development (GED) programs using a panel of earnings records and a rich set of individual information from administrative data in the state of Florida. Fixed effects estimates of the impact of participating in the GED education program show post-release quarterly earnings gains of about 15 percent...

This study investigated whether ethoxyresorufin-O-deethylase (EROD) activity in rainbow trout exposed to mixtures of polycyclic aromatic hydrocarbons (PAHs) could be predicted from induction equivalency factors (IEF). The test PAHs were classified into strong and weak inducers on the basis of similar exposure-response curves. Induction equivalency factors of strong inducers, based on benzo[k]fl...
