Curbing Child-Trafficking In Intercountry Adoptions: Will International Treaties And Adoption Moratoriums Accomplish The Job In Cambodia?, Kelly M. Wittner

Washington International Law Journal

Over the past two decades an enormous increase in intercountry adoptions has prompted international concern over the victimization of children, birth parents, and adoptive families. Recently, the United States has closely scrutinized babytrafficking in Cambodia. Reports of widespread buying, selling, and stealing of Cambodian infants for international adoption prompted the United States to place a moratorium on adoptions from Cambodia on December 21, 2001. In addition, the international community has drafted treaties such as the United Nations Convention on the Rights of the Child ("CRC") and the Hague Convention on Intercountry Adoption ("Hague Convention") to normalize and systematize the process …

Algae As Biological Indicators Of Stream Water Quality In Monteverde, Costa Rica, March 2003, Andrea Buckman

Monteverde Institute: Tropical Ecology and Conservation

Water quality is an issue of increasing importance as the growing population depletes and contaminates the Earth's natural resources. One example of this is in Monteverde, Costa Rica, where wastewater is directly discharged from homes and businesses into the many streams in the area, affecting the ecosystem within the streams. Runoff from the many farms and pastures that are treated with highly concentrated pesticides and fertilizers can also affect the natural freshwater ecosystems by adding nutrients and toxins. Seven streams in the Monteverde area were analyzed in order to determine if algae morphospecies can be used as reliable indicators of …

Understanding The Dynamic System Of Terrorist - Government Interaction, John A. Hanrahan

Theses and Dissertations

The nature of action and reaction that forms the basis for terrorist - government interactions creates a dynamic system. Understanding how this dynamic system behaves in response to key government activities can help the government better control the overall behavior of the system. The system dynamics methodology is one tool that can help the government solve specific behavioral problems within the overall system. This research shows the ability of system dynamics to help develop government policy towards terrorism that can directly affect a terrorist's behavior. It supports a government policy of offensive action instead of defensive reaction. It also identifies …

Optimizing An In Situ Bioremediation Technology To Manage Perchlorate-Contaminated Groundwater, Mark R. Knarr

Theses and Dissertations

Combining horizontal flow treatment wells (HFTWs) with in situ biodegradation is an innovative approach with the potential to remediate perchlorate-contaminated groundwater. A technology model was recently developed that combines the groundwater flow induced by HFTWs with in situ biodegration processes that result from using the HFTWs to mix electron donor into perchlorate-contaminated groundwater. A field demonstration of this approach is planned to begin this year. In order to apply the technology in the field, project managers need to understand how contaminated site conditions and technology design parameters impact technology performance. One way to gain this understanding is to use the …

A System Dynamics Investigation Of Genetic Drift And Translocation In The Red-Cockaded Woodpecker Metapopulation, Jason E. Yates

Theses and Dissertations

The red-cockaded woodpecker (Picoides borealis) is classified under the Endangered Species Act of 1973 as an endangered species As such, the red-cockaded woodpecker (RCW) is afforded strict protection in an effort to return the RCW population to a self-sustainable level. Endemic to southeastern United States mature pine forests, the presence of the RCW impacts the operations of many Department of Defense (DoD) installations. A particular challenge in sustaining what are often small populations of RCW at these locations is the loss of genetic variation due to genetic drift. The optimal method for mitigating such loss is through the artificial immigration, …

Palladium-Catalyzed Destruction Of Nitro Aromatic-Contaminated Groundwater, Dennis Landon Phillips

Theses and Dissertations

Of the over 17,000 DoD sites that potentially require remediation, sites containing soil and groundwater contaminated by energetic compounds are prevalent (Larson et al., 2001). Production of energetics such as 2,4,6-trinitrotoluene (TNT), hexahydro-1,3,5 - trinitro- 1,3,5 -triazine (RDX), and octahydro-1,3,5,7-tetranitro- 1,3,5,7-tetrasocine (HMX) for use in munitions has created a DoD-wide problem due to improper disposal techniques (Price et al., 2001), Nitro aromatic compounds (NACs) similar to those used in explosives can also be found in insecticides, herbicides, pharmaceuticals, dyes, plastics, and many other commonly used products. The natural breakdown of these contaminants creates byproducts such as amines, which are known …

Analysis Of Anion Distributions In The Developing Strata Of A Constructed Wetland Used For Chlorinated Ethene Remediation, Joshua D. Kovacic

Theses and Dissertations

Perchloroethene (PCE), Trichloroethene (TCE) and their degradation products are among the most common organic groundwater contaminants in the United States. Constructed wetlands utilizing upward flow harbor reduction-oxidation conditions that have demonstrated the potential to promote both partial and total mineralization of PCE and TCE through the process of natural attenuation. Organic acid and inorganic anion concentrations are indicative of reduction-oxidation processes that drive chlorinated ethene degradation. These analytes were investigated to assess their development within three vertically stratified regions of a constructed wetland cell at Wright-Patterson Air Force Base fed by groundwater contaminated with PCE and TCE. Data collected during …

Biochemical Composition Of Embryonic Blue Crabs Callinectes Sapidus Rathbun 1896 (Crustacea : Decapoda) From The Gulf Of Mexico, Janet R. Jacobs, Patricia M. Biesiot, Harriet M. Perry, Christine Trigg

Faculty Publications

Blue crab Callinectes sapidus embryos from the Mississippi Sound were sampled in spring and in late summer to determine patterns of biochemical composition and of yolk utilization during embryogenesis and to ascertain potential seasonal differences in biochemical composition. The diameter of spring embryos was similar to 6% greater than summer embryos but this significant size difference was due to increased water content, not to increased organic content. The general trend in initial biochemical composition was similar in both seasons; protein was the primary component at similar to 50% of initial dry weight followed by lipid (similar to 30%), ash (similar …

Wariness Of Coyotes To Camera Traps Relative To Social Status And Territory Boundaries, E.S. Sequin, Michael M. Jaeger, Peter F. Brussard, Reginald H. Barrett

United States Department of Agriculture Wildlife Services: Staff Publications

The primary objective of this study was to develop a better understanding of coyote (Canis latrans) wariness particularly as it related to social status. We determined that territory status (controlling alpha, resident beta, or nonterritorial transient) affected vulnerability to photo-capture by infrared-triggered camera systems. All coyotes were wary of cameras, leading to relatively low numbers of photo-captures, most of which occurred at night. Alphas were significantly underrepresented in photographs and were never photo-captured inside their awn territories. Betas were photographed inside and outside their territories, whereas transients were most often photographed on edges of territories. Both alphas and …

Regulation Of Chloride Permeability By Endogenously Produced Tyramine In The Drosophila Malpighian Tubule, Edward M. Blumenthal

Biological Sciences Faculty Research and Publications

The Malpighian (renal) tubule of Drosophila melanogaster is a useful model for studying epithelial transport. The purpose of this study was to identify factors responsible for modulating transepithelial chloride conductance in isolated tubules. I have found that tyrosine and several of its metabolites cause an increase in chloride conductance. The most potent of these agonists is tyramine, which is active at low nanomolar concentrations; the pharmacology of this response matches that of the previously published cloned insect tyramine receptor. In addition, the tubule appears capable of synthesizing tyramine from applied tyrosine, as shown by direct measurement of tyrosine decarboxylase activity. …

Effects Of Habitat Type On Predation Rates, March 2003, Erin Wilichowski

Monteverde Institute: Tropical Ecology and Conservation

High rates of habitat alteration increase the effects of fragmentation and creation of pasture. Degraded habitat can negatively affect predator abundance and hence predation. In this study, variation in predation rates between closed forest, open forest, and pasture were assessed for a matrix of degraded tropical premontane moist forest in Costa Rica. In order to compare predation rates in the different habitat types, non-toxic clay caterpillars were made, placed on understory leaves, and then rates of predation in each habitat type were determined. This study focused on three types of predators, insects, birds, and rodents, with insects as the most …
