As Information Technology enters its second era, it's encountering a paradigm shift that mirrors changes in the corporation itself. With no respect for traditional boundaries, it's breaking down walls and hierarchies--and, in the process, becoming an increasingly valuable strategic tool.
Imagine how bewildered you would feel if you had just been told by a doctor or a nurse that your kidneys had failed and that you would shortly require dialysis. This news is broken to 80 per million of the population or approximately 4000 people in the United Kingdom each year, and must come as a dreadful blow to each and every patient, their family, carers and friends.
This study was designed to determine whether styrene absorption through the skin results in measurable changes in biologic indicators of styrene exposure using a group of workers engaged in hand lay-up operations during which extensive styrene skin contact occurs. Serial measurements of expired breath and blood styrene and urinary excretion of mandelic and phenylglyoxylic acid were made in eight female workers during 4 consecutive days using different experimental conditions including either (1) gloves/protective clothing alone, (2) respirator alone, (3) both gloves/protective clothing and respirator, or (4) neither respirator nor gloves/protective clothing. A two-by-two factorial design imbedded in a Latin square design allowed estimation of the effects of the two types of protection (i.e., gloves/clothing and respiratory) and any interaction. Levels of styrene in venous blood and expired breath and urine mandelic and phenylglyoxylic acid excretion were no different when gloves/clothes were used as protection compared to no protection at all. Significant reduction in all biologic indices occurred when respiratory protection was used. The results of the study suggest that percutaneous absorption of styrene is not a significant exposure source and does not significantly contribute to the body burden of styrene of workers in the reinforced plastic industry engaged in hand lay-up operations. Respiratory protective devices were the most effective means for reducing styrene absorption. Even though skin absorption of styrene is limited, skin protection is necessary because of the risk of dermatitis.
This article describes the use of a socio-culturally specific framework for a pregnancy prevention program for low income 10 to 12 year old African American middle school girls. The framework expands earlier (Johnson, 1995) conceptualizations by combining African and African American frames of reference with behavior change processes to influence sexual decision-making among young adolescents.
