Triazine Herbicide Exposure And Breast Cancer Incidence: An Ecologic Study Of Kentucky Counties, Michele A. Kettles, Steven R. Browning, Timothy Scott Prince, Sanford W. Horstman Nov 1997

Triazine Herbicide Exposure And Breast Cancer Incidence: An Ecologic Study Of Kentucky Counties, Michele A. Kettles, Steven R. Browning, Timothy Scott Prince, Sanford W. Horstman

Preventive Medicine and Environmental Health Faculty Publications

The incidence of breast cancer in the United States has steadily increased for the past three decades. Exposure to excess estrogen, in both natural and synthetic forms, has been implicated as a risk factor for the development of this disease. Considerable interest has been focused on organochlorines, such as the triazine herbicides, and their possible role in the initiation or promotion of human breast cancer. To explore this relationship, an ecologic study of Kentucky counties was designed. Exposure to triazines was estimated by use of water contamination data, corn crop production, and pesticide use data. A summary index of triazine …

Responding To Price Signals In Communal Agriculture: Shaker Hog Production, 1788-1850, John E. Murray, Metin M. Cosgel Nov 1997

Responding To Price Signals In Communal Agriculture: Shaker Hog Production, 1788-1850, John E. Murray, Metin M. Cosgel

Economics Working Papers

Isolated Shaker communal farms stressed self-sufficiency as an ideal but carefully chose which goods to buy and sell in external markets and which to produce and consume themselves. We use records of hog slaughter weights to investigate the extent to which the Shakers incorporated market-based price information in determining production levels of a consumption good which they did not sell in external markets: pork. Granger causality tests indicate that Shaker pork production decisions were influenced as hypothesized, strongly by corn prices and weakly by pork prices. We infer that attention to opportunity costs of goods that they produced and consumed …


Effect Of Application Frequency On The Fate Of Azinphosmethyl In A Sugercane Field (Bulletin #863), H. M. Selim, R. L. Bengtson, L. M. Southwick, R. Ricaud, H. P. Schexnayder Nov 1997

LSU AgCenter Bulletins

Reducing the amounts of dissolved substances in surface and ground water is of major concern nationally and within the agricultural community. The primary focus of this study was to investigate the fate of azinphosmethyl (Guthion®) in sugarcane canopy, soil and runoff water.


Socioeconomic Status And Health In Blacks And Whites: The Problem Of Residual Confounding And The Resiliency Of Race, Jay S. Kaufman, Richard S. Cooper, Daniel L. Mcgee Nov 1997

Socioeconomic Status And Health In Blacks And Whites: The Problem Of Residual Confounding And The Resiliency Of Race, Jay S. Kaufman, Richard S. Cooper, Daniel L. Mcgee

Faculty Publications

A large number of epidemiologic studies have focused on racial/ethnic differences, particularly between blacks and whites. Because health endpoints and racial categorizations are associated with socioeconomic status, investigator, generally adjust for socioeconomic indicators. The intention is usually to control for confounding, thereby making groups comparable and excluding socioeconomic status as an alternative explanation to hypotheses of innate physiologic differences. A threat to the validity of these analyses is therefore the presence of residual confounding. We identify four potential sources of residual confounding in this analytical design: categorization of socioeconomic status variables, measurement error in socioeconomic indicators, use of aggregated socioeconomic …
