The semi-parametric approach to the analysis of proportional hazards survival data
is relatively new, having been initiated in 1972 by Sir David Cox, who restricted its use
to hypothesis tests and confidence intervals for fixed effects in a regression setting.
Practitioners have begun to diversify applications of this model, constructing...
Depression is one of the most important psychiatric
disorders. It does not only affect the patients themselves
but also influences their family members, friends, and
society as a whole. The primary purpose of this paper is to
discuss the general characteristics of depression in terms
of the explanations provided by...
The study was devoted to formulating answers to the following
questions:
1. What factors did students report to be influential in their
choice of a community college major ?
2. What factors influenced students in the selection of a
community college to attend?
3. What factors influenced students to continue...
I examined two amphibian communities to assess factors
that may impact amphibian biodiversity. The results suggest
that the potential factors which influence the maintenance
of amphibian biodiversity are multi-faceted and thus,
attempts to understand these factors must reflect these
complexities.
I investigated factors that influenced the susceptibility
of western toad...
This correlational study examined the perceptions of 45
pairs of masters-level intern students and their field-site
supervisors from the perspective of their supervisory working
alliance and a specific personality characteristic, optimism-pessimism.
Supervisory pairs completed the Supervisor or
Supervisee Demographic Questionnaire, the Working Alliance
Inventory Revised, the Supervisory Working Alliance
Inventory,...
Adolescent pregnancy is a major social problem which results in negative psychological, medical, developmental,
economic and educational consequences for both mother and child. A review of the literature examined psychological and sociocultural factors and negative consequences associated with adolescent pregnancy. There has been little research on age specific differences between...
The giant hairy desert scorpion, Hadrurus arizonensis, is a long-lived species
of North American scorpion that is presented here as an important model for research
in mating systems evolution and sexual selection. Many behaviors found in this
species were undocumented and are described here for the first time. This thesis...
I examined the biomechanical factors that influence the sizes of intertidal macroalgae by studying a population of Fucus gardneri at Fogarty Creek Point, OR. I constructed a mathematical model to predict optimal sizes and probabilities of survival for Fucus under conditions of high and low wave exposure. Predicted optimal sizes...
