A striking feature in the study of Riemannian manifolds of positive sectional curvature
is the narrowness of the collection of known examples. In this thesis, we examine the
structure of the cohomology rings of three families of compact simply connected seven dimensional
Riemannian manifolds that may contain new examples of...
That graduate study is detrimental to marriages has received empirical
support. This study utilized systems theory to examine and help explain the
dissolution process of graduate student marriages. Specifically, it examined the
impact of marital structure on perceptions of marital quality. Drawing primarily
from Scheinkman's (1988) qualitative study, spouses in...
This study examined the impact of a Sex Education Workshop on mothers' responses to their children's sexual questions and behaviors Subjects included 88 mothers equally divided into experimental and control groups. Experimental and control groups consisted of an equal number of mothers from high and low socioeconomic levels. Furthermore, an...
From May 1999 through April 2000, I interned with the Alaska Wilderness Recreation and Tourism Association (AWRTA), a non-profit organization that balances responsible tourism development with resource protection and community enhancement. I was assigned to a seven-member task force charged with evaluating the success of AWRTA's "Ecotourism Guidelines2" and was...
Cosmogenic-burial and U-series dating, identification of fluvial terraces and lacustrine
deposits, and river-profile reconstructions show that capture of the Gunnison River by
the Colorado River and abandonment of Unaweep Canyon occurred between 1.4-0.8
Ma. This event led to a rapid pulse of incision unlike any documented in the Rocky
Mountains....
This study was designed to enhance understanding of factors influencing foraging distribution, diet composition, and overall
reproductive success of Caspian terns (Sterna caspia) nesting on East
Sand Island in the Columbia River estuary. This colony of nearly
10,000 breeding pairs is of concern to regional resource managers
because Caspian terns...
The complexity of natural resources management has challenged the most willing governments and their most
dedicated scientists. The many intangible dimensions of the environment have defeated the most creative valuation methods.
Recently, more and more professionals and researchers have turned to religious teachings about nature and society, in order to...
The “Lake Chad” is one of the world, largest and most historical Lake located in the Sahel region of
Africa (lat. 12:30 N to 14:30 N and long. 13:00E to
15:30 E ) which is one of the most vulnerable regions
to climate change bordering North-Eastern Nigeria,
North-Western Cameroon, South-Eastern...
A direct numerical simulation of advection-diffusion in a sinusoidal tube was
carried out using the commercial finite-volume code STAR-CD. The Reynolds
numbers varied from Re = 0.1 to Re = 14.5. At the larger Reynolds numbers,
steady-state eddies formed in the diverging sections and significantly influenced
the macroscale dispersion. Long...
An interpretative philosophical framework was applied to a case study to document the particular experiences and perspectives of ten women engineering transfer students
who once attended a community college and are currently enrolled in one of two university
professional engineering programs. This study is important because women still do not...
