Commentary on the 1985 NASA/Vanderbilt Symposium on Future Hypervelocity Flight Requirements

The discussion, started in Semiannual Status Report Number 1, on aerothermal problems of hypervelocity flight and experiments that may lead to significant improvements in analytical/computational predictive methods, continues. The commentary is based on presentations made by speakers at a symposium on this subject held in December 1985. Symposium participants focused on the serious deficiencies that exist in knowledge of real-gas, nonequilibrium thermochemical-kinetic processes, catalytic processes, surface and shock slip, gas/surface interaction, boundary layer transition, and vortical leeside flows under hypervelocity conditions. Programs of laboratory research and computations leading toward in-flight experiments were recommended. Feasibility of appropriate measurement techniques for the flight environment was assessed and problems for study in that area identified. A synopsis of the oral presentations is given

A simulation study of Large Area Crop Inventory Experiment (LACIE) technology

The author has identified the following significant results. The LACIE performance predictor (LPP) was used to replicate LACIE phase 2 for a 15 year period, using accuracy assessment results for phase 2 error components. Results indicated that the (LPP) simulated the LACIE phase 2 procedures reasonably well. For the 15 year simulation, only 7 of the 15 production estimates were within 10 percent of the true production. The simulations indicated that the acreage estimator, based on CAMS phase 2 procedures, has a negative bias. This bias was too large to support the 90/90 criterion with the CV observed and simulated for the phase 2 production estimator. Results of this simulation study validate the theory that the acreage variance estimator in LACIE was conservative

Has structural change contributed to a jobless recovery?

The current recovery has seen steady growth in output but no corresponding rise in employment. A look at layoff trends and industry job gains and losses in 2001-03 suggests that structural change - the permanent relocation of workers from some industries to others - may help explain the stalled growth in jobs.Business cycles ; Employment (Economic theory) ; Labor mobility ; Unemployment ; Industries ; Recessions

Thermocouple installation

A thermocouple assembly which includes a plug having a pair of small diameter holes near one end thereof which are spaced a small distance apart to leave a thin quantity of plug material between the holes is presented. There are a pair of thermocouple wires extending through the different holes and with the outer ends of the wires joined to the thin quantity of plug material which lies between the holes to form a thermocouple junction

Thomas Hardy deals with women in many harsh manners in his novels. His harshness stems from a lifetime of being controlled by self-asserting women, and he takes his revenge on such women in his novels. The excuse of personal experience only takes the understanding of his literature so far. Like many other authors of his period, Hardy used his writing ability to comment on the state of society. With the "new" woman coming to the forefront in Victorian England, he found it necessary to compare the values and lifestyles of traditional women with those of the new order. Invariably, the traditional, proper Victorian woman showed that she held superiority to the new woman. In the five novels discussed in this paper, seven women stand trial in front of Hardy. Three survive their plots and show the triumph of tradition versus self-assertion. The four who do not enjoy happy endings cannot handle the consequences of their independent actions. The women of Far From the Madding Crowd, The Return of the Native, The Mayor of Casterbridge, Tess of the D'Urbervilles, and Jude The Obscure all provide encouragement and warnings to Victorian women. Hardy tells them that they must embrace their mothers' and grandmothers' values, or face terrible repercussions. Women cannot be independent and still have a suitable relationship with a man, though several of his heroines tried

DEMOGRAPHIC RESEARCH

Background: Mexican women in the United States (US) have higher rates of fertility compared to other ethnic groups and women in Mexico. Whether variation in women’s access to family planning services or patterns of contraceptive use contributes to this higher fertility has received little attention. Objective: We explore Mexican women’s contraceptive use, taking into account women’s place in the reproductive life course. Methods: Using nationally representative samples from the US (National Survey of Family Growth) and Mexico (Encuesta National de la Dinámica Demográfica), we compared the parity-specific frequency of contraceptive use and fertility intentions for non-migrant women, foreign-born Mexicans in the US, US-born Mexicans, and whites. Results: Mexican women in the US were less likely to use IUDs and more likely to use hormonal contraception than women in Mexico. Female sterilization was the most common method among higher parity women in both the US and Mexico, however, foreign-born Mexicans were less likely to be sterilized, and the least likely to use any permanent contraceptive method. Although foreign-born Mexicans were slightly less likely to report that they did not want more children, differences in method use remained after controlling for women’s fertility intentionsPopulation Research Cente
