Hard Colour Singlet Exchange at the Tevatron

We have performed a detailed phenomenological investigation of the hard colour singlet exchange process which is observed at the Tevatron in events which have a large rapidity gap between outgoing jets. We include the effects of multiple interactions to obtain a prediction for the gap survival factor. Comparing the data on the fraction of gap events with the prediction from BFKL pomeron exchange we find agreement provided that a constant value of alpha_s is used in the BFKL calculation. Moreover, the value of alpha_s is in line with that extracted from measurements made at HERA.Comment: 22 pages, 19 figure

Double Diffractive Higgs and Di-photon Production at the Tevatron and LHC

We use the POMWIG Monte Carlo generator to predict the cross-sections for double diffractive higgs and di-photon production at the Tevatron and LHC. We find that the higgs production cross-section is too small to be observable at Tevatron energies, and even at the LHC observation would be difficult. Double diffractive di-photon production, however, should be observable within one year of Tevatron Run II.Comment: 7 pages, 8 figure

A SIMPLE ALTERNATIVE TO THE STANDARD STATISTICAL MODEL FOR THE ANALYSIS OF FIELD EXPERIMENTS WITH LATIN SQUARE DESIGNS

Latin Square (LS) designs have long been advocated for field crop experiments on the grounds that \u27. . . soil fertility and other variations in two directions are controlled.\u27 As counter-evidence, the published standard analyses of eight LS experiments showed that in only two did the sum of squares for both between-rows and between-columns account for appreciable background variability. Regarding the background concomitant variability as a continuous surface to which treatment effects are additive, it is suggested that a contributory shortcoming of the standard model is that it admits only a restricted class of surfaces because parameters for warp, or row x column interaction, components are excluded. It is shown that, at the loss of some orthogonality between background and treatment effects, the deficiency can be remedied by fitting a more general polynomial surface. The principle is exemplified using a backward selection mUltiple regression procedure to analyze LS data in Cochran and Cox (1957). The procedure gave a considerable reduction in the coefficient of variation, from 12.9 to 6.3%, and permitted more sensible inferences than those (null) from the standard analysis. A note on medieval cultivation practices and experimental design is appended

Essentialism, Social Construction, or Individual Differences

Per the United States Department of Labor Women’s Bureau’s latest available statistics, the percentage of women employed in computer and information technology occupations was consistently lower than the average for all occupations. When broken down by selected characteristics, these numbers range from 12.4% in computer network architectures to 35.2% in web development. Is this trend reflected in the libraries? Although no comprehensive statistics are available for women in library IT, Lamont’s study does reflect the same trend in that the number of women as library IT department heads has been about one half that of men between 2004-2008. Why is there an under representation of women in library IT leadership? Is gender a concern? To answer this question, a more essential question should be addressed, i.e. what makes a successful IT supervisor in libraries? We posit that a successful supervisor is reflected in the morale and self-esteem of their reports, as well as in the integrity, productivity, and efficiency of the department or group they head

Perceived Effectiveness of Youth-Adult Partnerships on Enhancing Life Skill Development through 4-H

The purpose of this study was to determine if youth and adult participants in the 4-H Environmental Impact program perceive youth?adult partnerships as an effective means to enhance the youths’ development of life skills. The study further sought to discover the perceived obstacles that may keep youth and adults from participating in equal partnerships. The life skills of: Leadership, Cooperation, Service Learning, and Planning and organizing were enhanced through the youths’ participation in the youth-adult partnership. Through this research there was evidence that many of the youth participants did perceive themselves as equal team members when participating in this youth-adult partnership. The research indicated the greatest perceived obstacle that kept youth from engaging was not much time after homework and other activities. It is recommended that all participants in newly formed youth-adult partnerships receive training on how to implement this type of program, and how to participate equally

Re-engineering the Multimission Command System at the Jet Propulsion Laboratory

The Operations Engineering Lab (OEL) at JPL has developed the multimission command system as part of JPL's Advanced Multimission Operations System. The command system provides an advanced multimission environment for secure, concurrent commanding of multiple spacecraft. The command functions include real-time command generation, command translation and radiation, status reporting, some remote control of Deep Space Network antenna functions, and command file management. The mission-independent architecture has allowed easy adaptation to new flight projects and the system currently supports all JPL planetary missions (Voyager, Galileo, Magellan, Ulysses, Mars Pathfinder, and CASSINI). This paper will discuss the design and implementation of the command software, especially trade-offs and lessons learned from practical operational use. The lessons learned have resulted in a re-engineering of the command system, especially in its user interface and new automation capabilities. The redesign has allowed streamlining of command operations with significant improvements in productivity and ease of use. In addition, the new system has provided a command capability that works equally well for real-time operations and within a spacecraft testbed. This paper will also discuss new development work including a multimission command database toolkit, a universal command translator for sequencing and real-time commands, and incorporation of telecommand capabilities for new missions
