Description and analysis of variation in dairy product and concomitant nutrient purchases between Hispanic and non -Hispanic households using a panel of shoppers' purchase records

The purpose of this research was development of a method of estimating nutrient availability in populations as approximated by supermarket purchase records. Demographic information describing 12,516 panel households was obtained from a marketing and advertising program operated by H. E. Butt Grocery Company of San Antonio, Texas. A non-probability sample of 2,161 households meeting expenditure criteria was selected and all purchases of dairy products for this sample of households were organized into a database constructed to facilitate the retrieval, aggregation, and analysis of dairy product purchases and their nutrient contents. Two hypotheses were tested: (1) no difference would be found between Hispanic and non-Hispanic purchases of dairy product categories during the study period and (2) no difference would be found between Hispanic and non-Hispanic purchases of nutrients contained in those dairy products during the thirteen-week study period.^ Food purchase records were used to estimate nutrient exposure on a weekly, per capita basis for Hispanic and non-Hispanic households by linking some 40,000 dairy purchase Universal Product code (UPC) numbers with food composition values contained in USDA Handbook 8-1. Results of this study suggest Hispanic sample households consistently purchased fewer dairy products than did non-Hispanic sample households and consequently had fewer nutrients available from dairy purchases. While weekly expenditures for dairy products among the sample households remained relatively constant during the study period, shifts in the types of dairy products purchased were observed. The effect of ethnicity on dairy product and nutrient purchases was significant over the thirteen-week period. A database consisting of customer, household, and purchase information can be developed to successfully associate food item UPC numbers with a standard reference of food composition to estimate nutrient availability in a population over extended periods of time. ^

Coal purchase optimization: a review from Spain

The study addresses the need to manage the risk of the purchase price of coal in a power company by changing the management model of the purchasing department. It eliminates the risk of price reduces the cost of buying coal and optimizing the performance of all electricity generation plants belonging to the company. You get more flexibility and optionallity to gain additional benefits both economic and efficiency in the supply to our generation fleet. The tools to achieve the above purpose will be financial derivatives that will be used as elements of management and not as mere speculation in the markets.

Enhancing Conservation Options: An Argument for Statutory Recognition of Options to Purchase Conservation Easements (OPCEs)

The most dynamic component of the conservation movement in the United States for the past three decades has been land conservation transactions. In the United States, land conservation organizations have protected roughly 40 million acres of land through transactions. Most of these acres have been protected using conservation easements. Climate change threatens the vast conservation edifice created by land conservation transactions. The tools of land conservation transactions are, traditionally, stationary. Climate change means that the resources that land conservation transactions were intended to protect may no longer remain on the land protected. Options to purchase conservation easements (OPCEs) have long played a modest but important role in conservation law practice. In the world climate change is creating, with its substantial uncertainties and shifting windows of opportunity, OPCEs can serve more complicated and strategic purposes. The ability of OPCEs to serve important roles in protecting land in the context of uncertainty would be significantly increased if state legislatures amend current conservation easement statutes to (1) specifically recognize OPCEs, (2) immunize OPCEs from a range of potential common law challenges, (3) guarantee the durability and transferability of OPCEs, and (4) integrate OPCEs into the burgeoning body of conservation easement law. These statutory amendments would do for OPCEs what conservation easement statutes have done for conservation easements: transform them into an essential multi-purpose tool for conservation in a changing world.

Louisiana Purchase Exposition, St. Louis, Missouri, 1904 (Raster Image)

This layer is a georeferenced raster image of the historic paper map entitled: Ground plan of the Louisiana Purchase Exposition St. Louis, MO 1904. It was published by Buxton & Skinner Stationery Co. Scale [1:7,500]. Covers the exposition grounds and buildings of the Saint Louis World's Fair, currently the Forest Park and Washington University area, St. Louis, Missouri. The image inside the map neatline is georeferenced to the surface of the earth and fit to the the Missouri East State Plane Coordinate System NAD83 (in Feet) (Fipszone 2401). All map collar and inset information is also available as part of the raster image, including any inset maps, profiles, statistical tables, directories, text, illustrations, index maps, legends, or other information associated with the principal map. This map shows features such as roads, railroads and stations, cable and electric car lines, drainage, lagoons and ponds, buildings, ground cover, paths, and more. Includes index. This layer is part of a selection of digitally scanned and georeferenced historic maps from The Harvard Map Collection as part of the Imaging the Urban Environment project. Maps selected for this project represent major urban areas and cities of the world, at various time periods. These maps typically portray both natural and manmade features at a large scale. The selection represents a range of regions, originators, ground condition dates, scales, and purposes.
