Employer fetal protection policies at work: Balancing reproductive hazards with Title VII rights
Perhaps one of the most compelling divisive workplace issues of the decade surrounds the use of increasingly complex chemicals in work environments which raises legal, economic, medical and moral concerns, especially as employers adopt employment policies meant to avoid the specter of massive tort liability for workplace exposure injuries to workers or third parties. In the case, /International Union v. Johnson Controls, the Supreme Court struck down an employer's policy prohibiting fertile women from work involving exposure to the well-known teratogen, lead, where the employer could not produce a defense to this facially discriminatory policy. The authors analyze the Court's opinion and concurrences, and note the important tensions still needed resolution after the case: namely the public policy mandate to protect all populations from workplace toxins; to eradicate toxins from the workplace; and to promote worker and safety health of both men and women.
Revising the Minimum Wage for the 1990s
This article examines the federal-wage floor concept of the Fair Labor Standards Act of 1938 (FLSA) in light of the current legislative debate to increase the minimum wage. The arguments of proponents and opponents of the initial minimum wage law and its periodic increases have remained fairly constant over the past fifty years. The opponents' concerns about potential loss of jobs, negative impact upon businesses, and the economy and the questionable efficiency of the wage floor in reaching the neediest workers to eliminate poverty remain the most prevalent reasons cited. The harmful impact of a minimum wage increase on the competitiveness of U.S. business in the international sphere has emerged as the foremost issue of opponents in this decade.
EFFECT OF SAMPLE PREPARATION ON WATER TREE RESISTANCE OF XLPE/SEBS BLENDS
The effects of an aromatic polymer, such as poly[styrene-b-(ethylene-co-butylene)b-styrene] (SEBS), and its preparation processes on water tree resistance, morphology, crystallinity, dielectric constant and dielectric loss tangent of crosslinked polyethylene (XLPE)/SEBS and XLPE/SEBS/ethylene vinyl acetate (EVA) blends were investigated. The XLPE/SEBS samples were characterized by means of differential scanning calorimetry, scanning electron microscopy, dielectric spectral analysis and the accelerated water treeing experiment. The results clearly showed that although SEBS was partially compatible with LDPE and it was dispersed evenly in XLPE matrix, the blends demonstrated excellent dielectric performances, such as dielectric constant and dissipation factor. The crystallinity of XLPE/SEBS blends was decreased with increase in SEBS content and it was further decreased with the addition of EVA. SEBS could effectively improve the water-tree resistance of XLPE and both SEBS and EVA were found to improve the water tree resistance of XLPE synergistically as expected. The differences in sample preparation processes could change the phase morphology and dielectric performance of the blends, and could also influence the dispersion of SEBS in XLPE matrix as well as the crystallinity of the blends. Different preparation processes led to different water tree resistance behaviours of the samples. The improvement of SEBS dispersion in XLPE matrix helped to improve the water tree resistance of XLPE.
