To obtain data on the decomposition of the forest floor, a battery operated electrolytic respirometer was developed making it possible to measure CO₂ evolution from field moist forest floor samples in situ independent of root respiration. Banks of four respirometers powered by two 12-volt batteries were installed in three old...
Three deep experimental filters were used to evaluate the influence
of the physical factors of media size, depth of filter, and organic and hydraulic loading on contact time and the rate of removal
of organic material by the biological growth on the filters. A
further correlation was made between contact...
This study measures the recreational boating use in Prince William Sound, Alaska. Improved access conditions to the Sound over the last decade coupled with a statewide increase in outdoor recreation participation among both resident and out of state tourists have made the Sound a focal point for recreational boating in...
The problem of this study was to determine whether graduate students
in education (the experimentals) participating in a counseling
practicum would demonstrate a change in self-actualization which would
be significantly different when compared with other graduate students
in education (the comparisons) who were not participating in the above
program. The...
The objective of this study was to determine the internal consistency
rating for the Film Test for Understanding Behavior (FUB)
and the three subscales within the test. An estimation formula which
contrasts sums of squares generated from an analysis of variance
was used to compute the internal consistency reliability coefficients...
Modern science was produced by a Christian society,
and although science has had an effect on Christianity, it
could not itself remain unaffected. In the second half of
the nineteenth century, the subject of evolution was as
much a religious as a scientific issue. The battle line
was drawn and...
Industry today is pushing personal portable handheld communication de- vices, from cellular telephones to personal navigation systems, and society is embracing the push. The goal is to make compact multi-functional handheld products that can transfer information to those around us through high bandwidth mobile communications. These modules rely heavily on...
The influence of media size upon the effective removal
of organic waste from a liquid substrate was studied by the
use of three experimental trickling filters under a set
of uniform operating conditions. The range of experiments
involved hydraulic loadings of increasing magnitude and
of constant organic strength.
The trickling...
The analysis of prehistoric stone features has suffered for two separate but related reasons. The first is the lack of stringency in defining the terms attributed to these structures and, second, the perception of a lack of formal attributes exhibited by them. These two factors have made it impossible to...
In June of 2013, the U.S. Fish and Wildlife Service proposed removing gray wolves (Canis lupus, Linnaeus) from Endangered Species Act (ESA) protections throughout the conterminous United States. The proposed rule depends on a definition of endangerment that is inconsistent with the legislative history and historical implementation of the ESA,...
Shrub-steppe ecosystems of western North America provide habitat for many wildlife species, are important components of public and private rangelands, and offer recreational opportunities for millions of people. They are some of the most vulnerable ecosystems in the United States and have been altered by human activities such as livestock...
I developed a conceptual model of Douglas-fir bark beetle dynamics and associated host mortality across spatial and temporal scales. I proposed that a hierarchy of factors influence host resistance to attack at different spatial scales. I then tested this model by measuring the association between the occurrence of beetle-kill and...
The simplified equations of motion proposed by Morton to determine
the extent of vertical travel of a forced plume in a linear
density stratified environment were re-written and solved in a way
which allowed them to be applied to any non linear profile of density.
For application to any specific...
High Performance Liquid Chromatography-Mass Spectrometry coupled with filtration, centrifugation, and other common sample preparation techniques offers a rapid and robust method for separating and quantifying propofol, a commonly used anesthetic, from human blood and its synthetic analogs. Method development is important for not only optimizing separation and quantification for a...
Being old and female in America often means being alone and poor. To offset this outcome financial preparation for retirement should begin in the pre-retirement years. The purpose of this exploratory study was to assess the financial preparedness of mature, single women as they approach retirement by examining the relationships...
Historians and sociologists of science often identify the efflorescence of social stud ies of science with the work of postwar American intellectuals such as Robert K. Merton and Thomas S. Kuhn. They often also refer to the views of Michael Polanyi (1891-1976) on the roles of tacit knowledge, apprenticeship, social...
Mycobacterium avium subspecies paratuberculosis (MAP) is the causative agent of Johne’s disease, a chronic granulomatous enteritis that plagues domestic and wild ruminants globally. During the silent stages of Johne’s disease, infected animals intermittently shed bacteria for years prior to clinical diagnosis during advanced disease stages. This strategy allows MAP to...
When a student participates in a service break trip, a process called reorientation occurs after the trip is over, when the student is trying to connect what they’ve learned on the trip to their normal lives. The objective of this project was to explore the concepts of volunteerism, community service,...
