Persistent Poverty

This chapter describes the outcome of for-profit's rule in Burke County, Georgia. Burke County is what the US Department of Agriculture calls a persistent-poverty county, meaning that for the past thirty years, over 20 percent of the population has lived in poverty. The designation is not an easy one to get. Only 11.2 percent of counties nationally register as that poor, for that long. And most of such counties are rural. Poverty has been even worse lately in Burke County: 33.5 percent of the county lives in poverty. The region is part of what W. E. B. Du Bois called the Black Belt, for both its soil and people, where plantations once littered the landscape, providing the template for the later tenant-farm structure.

Food Commodities

Dr Wray's comments are, of course, very appropriate and encouraging. Aflatoxin was first detected in food commodities from other parts of the world. As concentrations in other parts of the world have usually been higher, little attention has been paid to the possibility of aflatoxin exposure in humans in the United States except by those who are directly involved in monitoring the human food supply (US Department of Agriculture, the food industry, and the US Food and Drug Administration).

Statistical inference is the process of drawing conclusions from samples of statistical data about things not fully described or recorded in those samples. During the 1920s, economists in the United States articulated a general approach to statistical inference that downplayed the value of the inferential measures derived from probability theory that later came to be central to the idea of statistical inference in economics. This approach is illustrated by the practices of economists of the Bureau of Economic Analysis of the US Department of Agriculture, who regularly analyzed statistical samples to forecast supplies of various agricultural products. Forecasting represents an interesting case for studying the development of inferential methods, as analysts receive regular feedback on the effectiveness of their inferences when forecasts are compared with actual events.

This chapter explores the inception of the USAF's two educational institutions: the Air University (AU), and the US Air Force Academy (USAFA). The chapter shows that the AU, building on the interwar experience of the ACTS (Air Corps Tactical School), was able as a graduate school to go beyond expectations by becoming a fertile hub for professional learning. Conversely USAFA by mirroring Army and Navy institutions, established an undergraduate school with a solid curriculum, if not innovative in its approach. Tied to the rise of an independent air force service, the establishment of AU and USAFA sponsored by important military figures such as Billy Mitchell and Dwight Eisenhower heralded the rise of airpower theory in the Cold War era.

Environmentally Safe

There is great incentive to discover biologically active natural products from higher plants that are more effective than synthetic agrochemicals and are environmentally safe. Research emphasis at the US Department of Agriculture has therefore been on the development of alternative approaches to utilizing natural plant products in pest management. Discovery and evaluation of natural product fungicides is largely dependent upon the availability of miniaturized antifungal bioassays. We report on the development of a miniaturized 24-well leaf disk assay for evaluating plant extracts and pure compounds. Compounds applied directly to the leaf surface can be evaluated in a dose-response for fungicidal activity and phytotoxicity. The assay is sensitive to microgram quantities, can determine chemical sensitivity between fungal isolates, and adaptable to complex mixtures, lipophilic extracts, and non-polar compounds. The use of digital imaging and analytical software provided quantitative data and the ability to fine tune the data analysis. Identification of new potential lead compounds can be repeated quickly in time and real on-the-leaf-surface activity can be evaluated in high throughput formats and published in a reasonable time.
