The Egyptian Coup, The United States, And A Call To Strengthen The Rule Of Law And Diplomacy Rather Than Military Counter-Terrorism, Thomas Mcdonnell

Elisabeth Haub School of Law Faculty Publications

This article examines from a legal and historical perspective (a) the United States’ implicit ratification of the Egyptian military’s overthrow of the first fairly and freely elected Egyptian president and (b) how the perceived U.S. support for the coup contributes to Islamic terrorism.

To guarantee that oil has been readily available (and during the Cold War to prevent the spread of communism), the U.S. has supported secular, authoritarian regimes in the Islamic world, including the House of Saud in Saudi Arabia, the Shah of Iran, Hosni Mubarak in Egypt, and, initially, Saddam Hussein in Iraq, not to mention autocratic leaders …

Sexual Assault Complaint Management From The Perspectives Of Ex-Military Air Force Leaders, Annmarie Macaraeg

Walden Dissertations and Doctoral Studies

Military sexual assault continues to be a persistent problem for the Department of Defense despite the development of new reporting procedures. A sexual assault in the military can cause a lapse in mission accomplishment, negatively interrupt the victim's career, and lead personnel to fail at meeting high standards and expectations. The management of sexual assault complaints in the military has not been effective in preventing sexual assaults from occurring. This grounded theory study looked to explain how military leadership approaches the sexual assault complaint management process. Bronfenbrenner's (1979) ecological model of human development was the conceptual lens used for this …

Agriculture is an indispensable part of every person’s life, ensuring that nutritious and inexpensive food is readily available. As any other organisms, plants are subject to numerous parasitic infections. Biological evolution has allowed plants to produce a variety of toxic compounds to deal with their pathogens. American pokeweed plant (Phytolacca americana) manufactures pokeweed antiviral protein, a ribosome inactivating protein that disrupts protein synthesis and lowers infectivity of many plant and animal viruses. The intricate mechanism of PAP antiviral activity entails a delicate coordination and interplay of several factors, allowing the plant to battle its invaders. Here, we examine the molecular …

Winter Conditions Influence Biological Responses Of Migrating Hummingbirds, Catherine H. Graham, Sarah R. Supp, Donald R. Powers, Pieter Beck, Marisa C. W. Lim, Anusha Shankar, Scott Goetz, Susan M. Wethington

Faculty Publications - Department of Biological & Molecular Science

Conserving biological diversity given ongoing environmental changes requires the knowledge of how organisms respond biologically to these changes; however, we rarely have this information. This data deficiency can be addressed with coordinated monitoring programs that provide field data across temporal and spatial scales and with process-based models, which provide a method for predicting how species, in particular migrating species that face different conditions across their range, will respond to climate change. We evaluate whether environmental conditions in the wintering grounds of broad-tailed hummingbirds influence physiological and behavioral attributes of their migration. To quantify winter ground conditions, we used operative temperature …

Do Community-Level Models Account For The Effects Of Biotic Interactions? A Comparison Of Community-Level And Species Distribution Modeling Of Rocky Mountain Conifers, Paige E. Copenhaver-Parry, Shannon Albeke, Daniel B. Tinker

Faculty Publications - Department of Biological & Molecular Science

Community-level models (CLMs) aim to improve species distribution modeling (SDM) methods by attempting to explicitly incorporate the influences of interacting species. However, the ability of CLMs to appropriately account for biotic interactions is unclear. We applied CLM and SDM methods to predict the distributions of three dominant conifer tree species in the U.S. Rocky Mountains and compared CLM and SDM predictive accuracy as well as the ability of each approach to accurately reproduce species co-occurrence patterns. We specifically evaluated the performance of two statistical algorithms, MARS and CForest, within both CLM and SDM frameworks. Across all species, differences in SDM …

Nitrogen And Warming Effects On Nitrous Oxide Production Associated With Coastal Macroinvertibrates, Melanie H. Gárate

Open Access Master's Theses

Bivalve shellfish potentially reduce excess nitrogen in the water column, however they can also be involved in the emission of nitrous oxide (N₂O), a potent greenhouse gas. Environmental controls on N₂O production from bivalves have not been well quantified. We tested responses of N2O production by three bivalves (Mytilus edulis, Mercenaria mercenaria and Crassostrea virginica) to nitrogen (N) loading and/or warming after immediate (1 day) and short-term (14-28 days) exposure. This two-factor laboratory study had four treatments: (1) ammonium nitrate (N) addition (targeting 100μM-N), (2) warming (22^oC), (3) N addition + …

The Synthesis Of Rotaxane Probes For Magnetic Resonance Imaging (Mri), Scott Macgill Karas

Open Access Master's Theses

Rotaxanes are simple molecules made by an interaction between a host and a guest.¹ Research has shown that rotaxanes have the capability of exchanging a hyperpolarized inert gas atom for use in Magnetic Resonance Imaging (MRI).² Currently, MRI contrast is enhanced by the injecting a magnetic gadolinium (III) [Gd(III)] ions into the human body prior to the imaging experiment.³ Unfortunately, these contrast agents are expensive and toxic; as a result, there is need for a cheaper and less toxic imaging agent. Additionally, it would be beneficial to develop targeted contrast agents, i.e. macromolecules that bind specific analytes, …
