This study examined the effect that three environmental
hues had on subjects' work performance and on mood levels of
anxiety, depression, and arousal in an office work environment.
Pre-test post- test measurements of differences in work performance
and mood levels were used to test twelve hypotheses. Work
performance was measured...
In probability and statistics, Simpson’s paradox is an apparent paradox in which a trend is present in different groups, but is reversed when the groups are combined. Joel Cohen (1986) has shown that continuously distributed lifetimes can never have a Simpson’s paradox. We investigate the same question for discrete random...
Steel moment-resisting frames (MRFs) are widely used in the United States to resist seismic forces. MRFs have many advantages, including architectural versatility, vetted member and connection detailing requirements, and high ductility for special MRFs (SMRF). However, MRFs require large members to meet story drift criteria. Moreover, strong-column-weak-beam requirements can result...
The purpose of this study was to determine if there were common
factors influencing student decisions to terminate course work at the
College of San Mateo, San Mateo, California.
The following six null hypotheses were tested:
1. There will be no significant difference in responses
among those enrolled in transfer...
Beginning in the late-nineteenth century, several dialogues emerged concerning life on Mars. Some supported the notion of an inhabited Mars, citing recent observations of the planet, while others, pointing to a lack of concrete evidence, denied the validity of such a bold hypothesis. The dialogues within and between different...
Thermodynamic properties of systems are often investigated computationally. Traditionally, thermal physics simulations are limited by their very small energy ranges and slow convergence. Broad histogram algorithms are a class of Monte Carlo algorithms that can explore an entire energy (and temperature) range in one thermal physics simulation: potentially saving months...
I. Performance and Carcass Quality of Broilers Raised on
Wire Flooring With and Without Padded Roosts
Two experiments were performed with broilers raised on
wire flooring with and without padded roosts to study the
effects of bird performance and carcass quality. Each
experiment had 480 straight-run commercial broilers
divided equally...
