The Eating Disorder Inventory (EDI) was administered to 3 female undergraduate samples representing 2 campuses (N?=?1,506). Subjects also provided information on family demographics and on eating, dieting, and exercise habits and attitudes. Very high rates of body dissatisfaction were reported. EDI factor analysis yielded a 6-factor structure accounting for 41% of the variance. The Eating Disorders factor was a combination of 3 EDI clinical scales (Drive for Thinness, Bulimia, and lack of Interoceptive Awareness); 5 factors were identical to the other 5 EDI scales. Two risk groups were identified on the basis of extreme EDI factor scores: a body-dissatisfied group and a binge-purge group with poor psychological adjustment. For campus intervention programs, potential usefulness of the EDI for screening of relevant subgroups is discussed, with particular attention to body dissatisfaction.

An alternative to cost/benefit analysis for analyzing the equity of electric power generation facility location, utilizing the potential for air quality degradation, is developed and applied to California. Siting issues motivating disagreement on facility location are reviewed. Equity concepts are introduced, and their implementation is discussed. Several measures for assessing the equity of facility location are proposed, and the equities of existing facility locations in California are analyzed for each measure. Equity considerations for future siting decisions are examined. 相似文献

The behavior described by Hu of a sharply decreasingr-value as the strain increased in a tensile test has been confirmed in two strongly textured steels, but only for conditions
of discontinuous yielding. It does not occur in the absence of interstitial elements when yielding is homogeneous. The present
work shows that two distinct anisotropies exist, one in the Luders range and one in subsequent uniform deformation. Possible
reasons for this behavior are discussed. The enhanced anisotropy due to discontinuous yielding does not confer benefits in
terms of improved drawability and it is recommended that prestrained or temper rolled material should be used when determingr-values.

The results of the first Faraday rotation measurement on the TFTR tokamak are presented. Data are reported on ohmic-as well as neutral-beam-heated plasmas including solid pellet injections. The procedure and the results of the calibration, are described. The effects of various errors in the measurements as well as the problem of cross coupling laser beams are studied. 相似文献

External memory (EM) algorithms are designed for large-scale computational problems in which the size of the internal memory of the computer is only a small fraction of the problem size. Typical EM algorithms are specially crafted for the EM situation. In the past, several attempts have been made to relate the large body of work on parallel algorithms to EM, but with limited success. The combination of EM computing, on multiple disks, with multiprocessor parallelism has been posted as a challenge by the ACM Working Group on Storage I/ O for Large-Scale Computing. In this paper we provide a simulation technique which produces efficient parallel EM algorithms from efficient BSP-like parallel algorithms. The techniques obtained can accommodate one or multiple processors on the EM target machine, each with one or more disks, and they also adapt to the disk blocking factor of the target machine. When applied to existing BSP-like algorithms, our simulation technique produces improved parallel EM algorithms for a large number of problems. 相似文献

An analysis of ohmic ignition criteria is presented, giving the requirements onT, n, andn/j in a form easily applicable to various confinement assumptions. For circular cross-section NeoAlcator tokamaks with Spitzer resistivity, a value ofB

a approximately equal to 250 T2m is required. The outstanding uncertainties in schemes to lower this value are how much increase in current density is achievable by plasma shaping and what the exact NeoAlcator coefficient is. 相似文献

Precipitable water vapour (PWV) was estimated over Lihue, Kauai, from AVHRR data using split-window techniques. The predicted values using the satellite sensor data were compared to precipitable water vapour amounts obtained from radiosondes and corrected GPS measurements. Compared to the corrected GPS precipitable water, the Dalu and RV satellite methods had rms errors of 7.3 and 3.8 mm, respectively. Typical values of PWV over Hawaii are approximately 27.5 mm, suggesting errors of about 14% in values estimated using the satellite split window technique near Hawaii. 相似文献

The Office of Global Analysis/International Production Assessment Division (OGA/IPAD) of the United States Department of Agriculture – Foreign Agricultural Service (USDA-FAS) has been assimilating new data and information products from agencies such as the National Aeronautics and Space Administration (NASA) into its operational decision support system (DSS). The FAS mission is to improve monthly estimates of global production of major agricultural commodities and provide US Government senior decision makers and the public the most accurate, timely, and objective assessment of the global food supply situation possible. These estimates are ultimately captured as the US governments’ official assessments of world food supply for the commodity markets and policy makers. The goal of this research was to measure changes in the quality and accuracy of decision support information resulting from the assimilation of new NASA products in the DSS. We gathered both qualitative and quantitative information through questionnaires and interviews to benchmark these changes. We used an interactive project lifecycle risk management tool developed for NASA mission spaceflight design and quality assurance (DDP – Defect Detection and Prevention) to do this. In this case, we used it to (1) quantify the change in DSS Objectives attained after assimilation of new products, and (2) evaluate the effectiveness of various Mitigation options against potential Risks. The change in Objectives attainment was considered the most important benchmarking indicator for examining the effectiveness of the assimilation of NASA products into OGA/IPAD’s DSS. From this research emerged a novel model for benchmarking DSSs that (1) promotes continuity and synergy within and between government agencies, (2) accommodates scientific, operational and architectural dynamics, and (3) facilitates transfer of knowledge among research, management, and decision-making agencies. 相似文献

On ratings of comfort and exertion by visual display unit users and ratings of workplace layout and working posture by expert ergonomists 总被引:1,自引:0,他引:1
Hutchinson TP 《Applied ergonomics》2008,39(1):131-2; discussion 133-4
Data sets comparing ratings of comfort and perceived exertion by visual display unit (VDU) users with ratings of workplace layout and working posture by expert ergonomists were published by Lindeg?rd et al. [2005. Concordance between VDU-users' ratings of comfort and perceived exertion with experts' observations of workplace layout and working postures. Appl. Ergon. 36, 319-325]. The present paper corrects the conclusions that were drawn. Users' and experts' ratings were very largely independent of each other. It is also noted that polychoric correlation is often an appropriate statistic for summarising the association in ordered tables of frequencies. 相似文献
