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...
This study in media anthropology uses participant observation, interviews, questionnaires, and recorded broadcasts to analyze how people use FM radio technology in the Koutiala area of southeast Mali, and particularly how they use FM radio to produce locality by relating audience members to one another, to the dominant national culture,...
Most cognitive research on conceptual structure has studied undergraduate populations and either natural (biological) or artificial (experiment-specific) categories. This project investigates how people with extensive, rich knowledge about a complex real-world domain organize and use that knowledge. The research extends prior work on differences among types of experts within biological...
The set of experiments described here test the hypothesis that the declarative memory system supported by the medial temporal lobe and habit/procedural memory supported by the basal ganglia are recruited when learning novel category representations. The theory guiding specific hypotheses about these neural systems and their operation in category learning...
The kinetoplastid protozoan <em>Trypanosoma brucei</em> is the causative agent of African trypanosomiasis, affecting humans, and Nagana disease, affecting cattle, prevalent in regions of sub-Saharan Africa. Our lab demonstrated that the flagellum of <em>T. brucei</em> is enriched in lipid rafts, membrane areas composed of sphingolipids, sterols, and proteins that serve as...
The vertebrate brain, which is made up of a vast array of individual neurons, is responsible for controlling numerous functions and behaviors, including distinguishing between visual cues, learning to navigate in a new environment, or making complex decisions. These neurons form specific networks that receive, process, and integrate chemical and...
Contemporary Ethiopian is, without question, facing enormous challenges. At the core of these challenges lay a state-building process major constituencies and elite groups were either alienated from, forced to acquiesce to, or coopted into. Unable to derive political legitimacy from democratic participation, successive governments largely relied on coercion and neopatrimonialism,...
This study examines how Cape Verdean theatre artists construct transformative performances of race, gender, language, and colonial history at the Mindelact International Theatre Festival on the Cape Verde Islands. The aim is to understand how international theatre festivals participate in the production and shaping of new social imaginaries about nationhood....
The finite element method is used to investigate failure mechanisms in pin-hanger connection in aging highway bridges. Bridge pins and hangers are typically considered as critical elements whose failure may result in partial or entire collapse of the structure. The primary function of a pin-hanger connection is to allow for...
The morphological evolution due to coarsening is analyzed for two distinctive types of microstructure. First, the feasibility of characterizing spatial correlations of interfacial curvature in topologically complex structures is demonstrated with the analysis of bicontinuous two-phase mixtures produced using phase field modeling. For structures produced with both conserved and nonconserved...
