Teaching health policy and politics in U.S. schools of public health.
Because most public health endeavors in the United States are funded by the public sector, public health practitioners need to be adept at working within the political system. However, the 1988 Institute of Medicine report, The Future of Public Health, found that many public health professionals are ignorant or disdainful of political processes and will not participate in activities that they perceive to be political. Our study examined the health policy and politics curricula of the 24 accredited schools of public health in the U.S., finding that most public health students are not exposed to these areas during their graduate coursework. Moreover, those students who do take health policy and politics courses study these areas within the context of health care delivery; the politics of public health and prevention are ignored by most schools of public health. Recommendations for improving public health curricula in health policy and politics are presented, including linkages with prevention activities.
Self-reported versus behavioral self-handicapping: empirical evidence for a theoretical distinction.
The present study was an investigation of how Ss would respond when given 2 self-handicapping options, 1 behavioral (withdrawal of practice effort) and 1 self-reported (reporting high levels of stress). Ss anticipating a diagnostic test of intellectual ability were given different instructions regarding the effects of stress and practice on test performance. Ss were told that (a) stress only, (b) practice only, (c) both stress and practice, or (d) neither stress nor practice affected test scores. Ss were then given the opportunity to self-report a handicap on a stress inventory and to behaviorally self-handicap by failing to practice before the test. High self-handicapping men and women showed evidence of self-reported handicapping, but only high self-handicapping men behaviorally self-handicapped. However, when both self-handicaps were viable, both high self-handicapping men and women preferred the self-reported over the behavioral self-handicap.

Rapid screening method for deoxynivalenol in agricultural commodities by fluorescent minicolumn.
A rapid screening procedure based on the selective adsorption of deoxynivalenol (DON) from extracts of wheat and corn has been developed. DON is extracted from the sample with acetonitrile-water (85 + 15) and partially purified on a preparative minicolumn. Solvent is evaporated and the residue is dissolved in toluene-acetone (95 + 5) and chromatographed on a novel detector minicolumn which selectively adsorbs DON. A blue fluorescence is produced when the column is heated 5 min at 100 degrees C. The procedure is capable of detecting DON at greater than or equal to 500 ng/g. Forty-three wheat samples, contaminated with DON at 60-6300 ng/g, were assayed by gas chromatography-mass spectroscopy (GC-MS) of the heptafluorobutyryl derivative of DON and by the selective adsorption procedure. Comparison of results showed 91% agreement between data from the 2 methods. Selective adsorption assays were positive for all samples that were greater than or equal to 500 ng/g by GC-MS (no false negatives) and were negative for 85% of samples less than 500 ng/g (4/27 false positives). These four samples contained greater than 200 ng/g by GC-MS. Samples of wheat (64), corn (23), soybeans (8), and sorghum (6) were extracted and extracts were assayed by thin-layer chromatography and the selective adsorption procedure. Selective adsorption assays agreed with TLC results.
