Nitrogen (N) deposition can alter belowground microbial communities, especially ectomycorrhizal (ECM) fungi, resulting in a reduced ability of associated trees to access organic nutrients. This study tested whether N addition decreases ECM species richness and shifts ECM species composition across spatial scales in a subtropical slash pine (Pinus elliottii) plantation...
Second harmonic generation (SHG),
a nonlinear optical tool, was used to
characterize DNA bound through a
chemical linker to the flat surface of a
hemispherical lens. Contact angle
measurements were used to guarantee
that the chemical linker did not hydrolyze
under experimental conditions. SHG
experiments followed the effects of salt...
Metal nanoparticles in polymeric matrices are of particular scientific interest due to their useful ability to self-assemble into complex nanocomposites. Recent examples involve using ultrathin diblock copolymers coupled with metal nanoparticles in the fabrication of novel electronic, magnetic and photonic devices. As this ordering process takes place far from equilibrium...
The linear food chain of high school biology textbooks has been replaced by the food web, the increasingly complex network of trophic interactions in an ecosystem. This complexity, however, masks a number of robust statistical properties. Yet much research to date has concentrated upon predicting and testing the existence of...
In chapter 1, we study the investment behavior of firms faced with uncertainty, irreversibility and non-convex adjustment costs when output can be stored. A discrete-time dynamic optimization problem is solved numerically using neural networks to study the investment problem. Our numerical results suggest that whether or not firms can store...
Gradient copolymers are novel materials that possess a gradual variation in composition along the chain, thereby forming an intermediate structure between random and block copolymers. As such, they are a model system to investigate the effect of molecular structure on fundamental properties of copolymers and may be useful in many...
This dissertation addresses questions in the fields of household finance and corporate finance. In Chapter 1, I use a quasi-experiment in Norway to examine how households respond to capital taxation. The introduction of a new wealth assessment methodology in 2010 led to geographic discontinuities in household exposure to wealth taxes,...
The object of this working paper is to present a new explanation for the behavior of rebel groups in relation to host communities. This study, which represents the main argument and ideas of my forthcoming dissertation, accounts for the change in rebel group behavior, from coercive to contractarian and vice...
Most scholars think of courts as a single category of adjudicative bodies or triadic dispute adjudication. But courts play a variety of roles in the domestic political system. Increasingly, the roles and tasks delegated to International Courts (ICs) mimic in form and content the roles and tasks delegated to courts...
From peacekeeping to telecommunication standards, the number, level of detail, and subject matter of international agreements have grown exponentially in recent decades. What are the consequences of the sheer complexity of international governance today? This symposium suggests a new framework to understand this proliferation of international accords: "international regime complexity."...
