The implementation of particular management practices to control the use of natural resources can unintentionally create barriers to trade in resources and resource access. Foreign firms have developed a variety of methods to bypass trade barriers. This thesis examines the use of foreign direct investment as a means of bypassing...
Heavy metals, such as copper, zinc, and cadmium, are ubiquitous in stormwater and potentially toxic to aquatic organisms at low concentrations. Removal of heavy metals contamination by conventional treatment is expensive and does not always reduce metals concentrations low enough to ensure safety of all aquatic species. This research seeks...
Relationships between myosin heavy chain (MHC) isoform content and
eccentric-induced damage were investigated in chemically skinned muscle fiber
segments. Fibers were subjected to an eccentric contraction standardized for strain
magnitude (0.25 fiber length) and velocity (0.50 maximal shortening velocity).
Fiber MHC isoform content was identified by SDS-PAGE. Pre- to post-eccentric...
Recent studies have found that equatorial Atlantic sea surface temperature (SST) variability may be influencing tropical Indian Ocean climate (Kucharski 2009, Wang 2009). Due to the economic and social impact of tropical cyclones, it is important to investigate how an Atlantic-Indian Ocean connection may be affecting tropical cyclone behavior in...
The dominant controls on flow generation in steep, forested hillslopes are poorly understood. This dissertation examined the dominant flow processes operating at the hillslope scale, using a combined macroscale measurement and model development and analysis framework. Irrigation experiments at two steep forested hillslopes were conducted to isolate individual hillslope flow...
This dissertation re-examines the now standard perceptual model of hillslope
hydrological response to rainfall, which includes the growth of a saturated wedge at the soil-bedrock interface or impeding layer. It also challenges the notion of bedrock impermeability and the assumption that the pattern of subsurface stormflow is determined by the...

The purpose of this study was to determine if a 5-month
progressive-resistance exercise program would affect measures
of activities of daily living (ADLs) and functional stability
in elderly women. All subjects were ambulatory women, 80 to
93 years old, who lived in assisted-care facilities. Eight
exercise and 7 control subjects...
Postmenopausat women on hormone replacement therapy (HRT) have been reported to be stronger when compared to women who are not using HRT. The first goal of this study was to investigate whether muscle morphology was altered in women who use HRT when compared to women who do not use HAT....
The relative role of cospeciation and host switching in the phylogenetic history of
ascomycete foliar symbionts is addressed in the orders Leotiales and Rhytismatales, fungi
associated predominantly with Pinaceae (Coniferales). Emphasis is placed on comparing
the evolution of the sister genera Pseudotsuga and Larix (Pinaceae) with that of the
pathogenic...
