Results of abundance surveys of juvenile Atlantic and gulf Menhaden, Brevoortia tyrannus and B. patronus
The estuarine populations of juvenile Atlantic and gulf menhaden (Brevoortia tyrannus and B. patronus) were sampled
during two-boat, surface-trawl, abundance surveys extensively conducted in the 1970s. Juvenile Atlantic menhaden were sampled in 39 estuarine streams along the U.S. Atlantic coast from northern Florida into Massachusetts. Juvenile gulf menhaden were sampled in 29 estuarine streams along the Gulf of Mexico from southeast Texas into western Florida. A stratified, two-stage, cluster sampling design was used. Annual estimates of relative juvenile abundance for each species of
menhaden were obtained from catch-effort data from the
surveys. There were no significant correlations, for either
species, between the relative juvenile abundance estimates and fishery-dependent estimates of year-class strength. From 1972 to 1975, the relative abundance of juvenile Atlantic menhaden in north Atlantic estuaries decreased to near zero. (PDF file contains 22 pages.
School Food Service Costs: Does Location Matter?
Over 30 million lunches and 9.8 million breakfasts are served every day to children in participating American schools through the USDA National School Lunch and School Breakfast Programs. It is challenging for participating local school food authorities (SFAs) to serve appealing, healthful meals while covering food, labor, and other operating costs with USDA reimbursements. But it may be more difficult for some SFAs than others due to cost differences across locations. Analysis of data from a large national sample reveals that after controlling for differences in SFA characteristics, sharp differences in costs remained among rural, urban, and suburban SFAs and across regions. The highest costs occurred in Mid-Atlantic, suburban SFAs and the lowest cost existed in southwest, urban SFAs. Differences in food costs explained the largest share of this variation.school meal costs, cost function, SFA, Food Consumption/Nutrition/Food Safety,
The Development of Education in Rhea County, Tennessee
Introduction: This thesis reports the evolution of the Rhea County School System from 1806 to 1960. The development of education begins with the early history of the county. The study shows the rise of private schools and academies. The beginning and growth of free elementary school and the beginning and development of secondary schools and colleges are shown.
There is no organized recorded history of education in Rhea County. There are very few early records pertaining to the development and operation of the schools in the county and those in existence are not readily available for use. As time passes, the possibility of the available information concerning the schools being lost or destroyed increases

SOME LEGAL PROBLEMS CONNECTED WITH STOCK MARKET TRANSACTIONS
If any one were asked what was the most dramatic event of the last year, he probably refer at once to the collapse of the great Bull Market on the New York Stock Exchange. This was not only a dramatic event, but it was literally a tragedy for hundreds of thousands of people. Securities shrank to less than half their former inflated values and hundreds of millions of dollars in cash and paper profits were lost over night, or possibly we should say over two nights, for the crash occurred in two stages, one in October and one in November, and many of those who staggered through the first were annihilated by the second. Never before had so many people been involved in stock market speculation, and, consequently, never before had so many people been directly hit by any stock market panic. Never before had so many dreams of El Dorado been shattered
The National School Lunch Program: Background, Trends, and Issues
The National School Lunch Program (NSLP) is the Nation’s second largest food and nutrition assistance program. In 2006, it operated in over 101,000 public and nonprofit private schools and provided over 28 million low-cost or free lunches to children on a typical school day at a Federal cost of $8 billion for the year. This report provides background information on the NSLP, including historical trends and participant characteristics. It also addresses steps being taken to meet challenges facing administrators of the program, including tradeoffs between nutritional quality of foods served, costs, and participation, as well as between program access and program integrity.National School Lunch Program, child nutrition, obesity, food assistance, Agricultural and Food Policy, Health Economics and Policy, Public Economics,
CONTRIBUTIONS OF NONALCOHOLIC BEVERAGES TO THE U.S. DIET
This report analyzes consumer demand and nutritional issues associated with nonalcoholic beverages purchased for at-home use by looking at demographic variables such as household size, household income, education level, and region. The beverages include milk, carbonated soft drinks, bottled water, fruit juices, fruit drinks, coffee, tea, and isotonics (sports drinks). The report's focus is on the impact of nutritional quality from beverage purchase choices that a household makes, looking at the household's availability of calories, calcium, vitamin C, and caffeine from these beverage choices. Using the Daily Values on the Nutrition Facts portion of the food label as a reference, we find that nonalcoholic beverages purchased for at-home consumption provided, on a per-person basis: 10 percent of daily value for calories; 20 percent of the daily value for calcium; 70 percent of daily value for vitamin C. Statistical analyses included the use of descriptive cross-tabulations and regression analyses, with profiles of households that were more or less likely to purchase the beverages, as well as key determinants associated with the probability of purchasing selected beverages.nonalcoholic beverages, nutrient intake, cross-tabulations, regression analyses, probit analyses, Food Consumption/Nutrition/Food Safety,
Meeting Report: The Use of Newborn Blood Spots in Environmental Research: Opportunities and Challenges
IntroductionDried blood spots (DBS) are routinely collected from newborns in the United States using a heel stick. The DBS are screened for inborn errors of metabolism and other disorders. More states are keeping residual spots and making them available for research purposes. DNA extraction from the DBS has been widely applied; however, the development of methods to measure a range of environmental toxicants in DBS has been a more recent goal for laboratory scientists and epidemiologists.ObjectivesThe purpose of the meeting was to examine the utility of DBS to measure environmental exposures. Speakers and discussants were invited to present data and discuss approaches to measure a range of analytes using DBS.ResultsThis meeting was held on 20 February 2007 at the University of North Carolina at Chapel Hill. The audience consisted of epidemiologists, chemists, and staff from state public health programs, the Centers for Disease Control and Prevention, and the National Institutes of Health. The meeting included presentations on measurement of flame-retarding chemicals and pesticides, metals, perchlorate, infectious agents, markers of immune status, and protein adducts. Analytical methods included mass spectrometry, atomic absorption, molecular methods, and microfluidic techniques. Significant progress was reported, but important challenges remain. Concerns including storage conditions, sample volume, contamination, and normalization require additional systematic evaluation. In addition, DBS storage and access policies require coordination.ConclusionsDBS remain a highly valuable resource for clinical, epidemiologic, and toxicologic investigation. The use of DBS to measure environmental exposures shows promise but additional work is necessary before more widespread use is warranted
