AbstractAn econometric model of cotton acreage response was estimated for four distinct production regions in the United States. This work builds on previous work in the area of supply response under government farm programs and provides up-to-date regionalized estimates of own-price elasticity of cotton acreage supply. The own-price variable used in this study is a weighted combination of expected market price and government policy variables. Results indicate regional similarity in response to own price but differences with respect to the prices of alternative enterprises. Differences in regional response to paid diversion are also indicated.

Based on the geographic distribution database of the Orthoptera Species File, the diversity and distribution of the superfamily Grylloidea in the Nearctic region was studied using the statistics and Sorensen dissimilarity coefficient. A total of 164 species or subspecies belonging to 4 families, 9 subfamilies and 27 genera were recorded from this region; among which Gryllidae (93, 56.70%), followed by Trigonidiidae (44, 26.83%), Mogoplistidae (25, 15.24%), and Phalangopsidae (2, 1.22%). The diversity exhibits an asymmetric distribution pattern, with the southeastern coastal plain, the Interior Plateau and Piedmont of the United States was the most abundant. At the same time, the regional similarity of species distribution was analyzed, and the Nearctic was divided into four subregions: Boreal & Arctic zone of North America, Eastern temperate North America, Northeast temperate North America, and Southern North America & western temperate North America.

Student bashing has become all the rage. Allan Bloom has decried today's youth as “spiritually unclad, unconnected, isolated, and no inherited or unconditional connection with anything or anyone,” creating a storm of controversy. E. D. Hirsch has declared students to be culturally illiterate and the National Geographic Society now tells us they are geographically illiterate, as well.Admittedly, statistics can be powerfully persuasive and the results of the recent National Geographic Society report should shake us up. One in seven Americans surveyed could not find the United States on a world map, let alone name the country in which “apartheid” is official government policy. Obviously, something larger than map skills is at stake here. As the survey demonstrated, a huge number of Americans know virtually nothing about world affairs. In a country whose influence is global, millions of people display indifference to, and ignorance of events, beyond our borders.Surveys deocumenting the educational shortcomings of U.S. students indeed have become a dime a dozen. Yet whether or not we agree with these assessments, we have been undeniably offered a grim evaluation of both our students and the job we have done with them. I question, however, whether Bloom's “back to basics” prescription or the acquisition of Hirsch's data base of 5,000 key facts will really make our students smarter, more aware of the complex world they live in. Can “great books” alone (and who will choose them?) or arbitrary concepts devoid of context prepare our students for an interdependent world in which nothing—including the role of the United States— is really certain? Nonetheless, we are compelled to take a good, hard look at ourselves, to reexamine and clarify our role as educators, and to reaffirm education as a potential and potent vehicle for change.

AbstractAn econometric model of planted wheat acreage was estimated for five distinct production regions in the United States. This structural investigation represents an update of previous published work with specific attention given to policy program variables, weather, production cost, risk, market price influences, and program participation. Estimated results indicated regional divergence in responsiveness to government program variables. The most significant divergence occurred in the Cornbelt and Southeast—soft red winter wheat areas. Results indicate that management of the wheat program from the USDA level will contain countervailing production incentives unless these regional characteristics are taken into consideration in policy directives.
