Statistical modeling has evolved around building increasingly more complex models, even though it is common knowledge among statisticians that an optimal model size usually exists for any given data set. Having overly complex models leads to imprecise parameter estimates and tends to increase the subjective role of the modeler, which...
Kanter (1977) conceptualized five dimensions of the
interdependence between work and family: occupational
subculture, job absorption, time and timing, rewards and
resources, and the emotional climate of work. Each of
these dimensions affects the functioning and satisfaction
of families and marriages. This research examined how
four of these dimensions (occupational...
The abolition of the Atlantic slave trade was a long struggle in
British Parliament between the slave trade defenders and the abolitionists.
The Act of 1807 officially abolished the Atlantic slave trade, eighteen years
after the initial abolition proposal to Parliament. William Wilberforce was a
member of a committee that...
Cometabolic biodegradation processes are potentially useful for the
bioremediation of hazardous waste sites. In this study the potential application of phenol-oxidizing
and nitrifying bacteria as "priming biocatalysts" was examined in the
degradation of polycyclic aromatic hydrocarbons (PAHs), aryl ethers, and aromatic
ethers. We observed that a phenol-oxidizing Pseudomonas strain cometabolically...
This project focuses on the classification of
vegetation as a habitat for wild turkeys. The
vegetation classification discussed here is only one
part of a study looking at habitat requirements,
seasonal use patterns, and brood-rearing habits of
wild turkeys in Southern Oregon. The vegetation
classification was performed for an area...
This thesis proposes an approximate maximum likelihood estimator and
likelihood ratio test for parameters in a generalized linear model when two or
more random effects are present. Substantial progress in parameter estimation
for such models has been made with methods involving generalized least squares
based on the approximate marginal mean...
