FLUID MILK PURCHASE PATTERNS IN THE SOUTH: EFFECTS OF USE OF NUTRITION INFORMATION AND HOUSEHOLD CHARACTERISTICS

This study measures the impacts of use of nutrition information and household socioeconomic characteristics on market participation and amount purchased of whole-fat and low-fat milks in the South. Data are from the 1987-88 Nationwide Food Consumption Survey. The results showed that use of nutrition information had little effect on purchases on the basis of nutritional benefits through health professionals and product packaging are useful tools for the dairy industry to attract market participation.Fluid milk, Household purchases, Market participation, Food Consumption/Nutrition/Food Safety,

Factors Associated with the Selection of Cooperative vs. Proprietary Handlers of Milk in Tennessee

Factors that influenced the decision by dairy farmers to select cooperatives milk handlers versus proprietary handlers were examined. In a 1989 survey, Tennessee dairy farmers were asked to indicate reasons that influenced their choice of milk handler, such as better price, an assured market, and better service. Characteristics of the dairy farmers were then compared between those who selected a specific reason and those who did not. Better service and an assured market were the most often cited reasons by cooperative members, and higher price and lower deductions were cited more often by nonmembers. Farmers who cited price as a reason tended to have larger dairy farms, be less diversified, and more indebted than those who did not cite price as a reason. Those who selected service as a reason had more dairying experience and were less indebted than those who did not select service.Agribusiness, Livestock Production/Industries,

JAWS multiple Doppler derived winds

An elementary working knowledge is given of the advantages and limitations of the multiple Doppler radar analyses that have recently become available from the Joint Airport Weather Studies (JAWS) project. What Doppler radar is and what it does is addressed and the way Doppler radars were used in the JAWS project to gather wind shear data is described. The working definition of wind shear used is winds that affect aircraft flight over a span of 15 to 45 seconds and turbulence is defined as air motion that cause abrupt aircraft motions. The JAWS data current available contain no turbulence data. The concept of multiple Doppler analysis and the geometry of how it works are described, followed by an explanation of how data gathered in radar space are interpolated to a common Cartesian coordinate system and the limitations involved. A discussion is also presented of the analysis grid and how it was constructed. What the user actually gets is discussed, followed by a discussion of the expected errors in the three orthogonal wind components. Finally, a discussion is presented of why JAWS data are significant

Looming Threats to Society Journals

Now is not the time for members of professional scientific societies to be complacent or unengaged. The American Chemical Society Publications Division, as well as other learned society publishers, such as the Royal Society of Chemistry, may be overly confident that the obvious high quality of their journals will ensure their position against commercial competitors. In addition, when they resist open-access efforts, society publishers appear to be more aligned strategically with commercial publishers' short-term perspective than with the research community's need to easily access all relevant content over the long term. Societies need to adhere closely to their members' needs, even if that means a break with their for-profit counterparts. University faculty and administrators need to engage with librarians to ensure that the best decisions are being made for the long term

Economic Impacts of Red Tide Events on Restaurant Sales

The economic impact of red tide events were examined for three Southwest Florida waterfront restaurants. Daily gross sales from January 1996 through September were analyzed using a multiple regression time series model to examine whether the presence of a red tide, as measured within three and six miles of the beach, reduced sales revenues. Preliminary results indicate that red tide blooms closer to shore had a significantly large negative influence on sales revenues across restaurant locations.Agribusiness,

Current Status of the Northern Saw-whet Owl (Aegolius acadicus) in Arkansas

The secretive Northern Saw-whet Owl (Aegolius acadicus) is believed to be much more widespread during fall and winter than previously thought. Of the few places in the southern United States conducting research on this species, all have been successful at capturing birds. A total of 12 historic records existed for Arkansas until our work began in fall of 2014. The first confirmed record was in 1959 and the most recent, prior to this research, was in 2010. Over the course of two field seasons, we captured and banded 24 Northern Saw-whet Owls in rural Madison County. All birds were mist-netted along a trail, in woodland composed of pine and cedar with fairly dense undergrowth. Two were captured during our 2014 season after a late start and 22 were captured in 2015, likely the result of an earlier start. Comparing our data to that of several other banding operations in the south, it would appear that the peak of migration in Arkansas is late October through early November, with capture rates dropping by early December. Of the birds captured, all but one was female, the most common sex this far south. A variety of age classes were identified, with a fairly even distribution of hatch-year, second-year, and after-second-year birds. Exactly from where the saw-whets are migrating is unknown, although several foreign recoveries in Missouri and four recoveries in Arkansas suggest they are coming from the western Great Lakes region. Once considered a vagrant, based on this research, the saw-whet appears to be a fall migrant to the state of Arkansas

THE DEMAND FOR BUTTER, MARGARINE, AND OILS: A NONPARAMETRIC TEST FOR EVIDENCE OF STRUCTURAL CHANGE

The objective of this study was to determine whether structural change in the demand for butter, margarine, and salad and cooking oils occurred between 1967 and 1986. A nonparametric method, which does not require that a functional form be imposed on the data, was used to test for violations from stable, well-behaved preferences. Violations were found, but they were small in magnitude. Therefore, the results failed to show strong evidence that consumption patterns for butter, margarine, and oils were inconsistent with stable preferences.Demand and Price Analysis,

Quantum Gravity Momentum Representation and Maximum Invariant Energy

We use the idea of the symmetry between the spacetime coordinates x^\mu and the energy-momentum p^\mu in quantum theory to construct a momentum space quantum gravity geometry with a metric s_{\mu\nu} and a curvature P^\lambda_{\mu\nu\rho}. For a closed maximally symmetric momentum space with a constant 3-curvature, the volume of the p-space admits a cutoff with an invariant maximum momentum a. A Wheeler-DeWitt-type wave equation is obtained in the momentum space representation. The vacuum energy density and the self-energy of a charged particle are shown to be finite, and modifications of the electromagnetic radiation density and the entropy density of a system of particles occur for high frequencies.Comment: 16 pages, LateX file, no figure
