The Autonomous Region of the North Atlantic of Nicaragua (RAAN) gained political autonomy in 1987 after indigenous Miskitu took up arms against the Nicaraguan government. As part of the autonomy process RAAN officials developed a policy document, The Health Model of the RAAN, that guides regional health system reform. The Health Model is guided by the concept of intercu....

Chromosomal alterations can arise from numerous events, including errors during cell division or repair of damaged DNA. Of these errors, segregational defects such as anaphase bridges and multipolar spindles play a major role in chromosomal instability, leading to tumorigenesis. Bridges can theoretically be produced by several mechanisms including telomere-telomere fusi....

Research has repeatedly demonstrated that herbivores can, at some times and in some places, control the distribution and abundance of plants. Consequently, explaining variation in herbivore control over plant communities is a central goal in ecology and evolutionary biology. Two major challenges have prevented theoretical progress in this area of research. First, althou....

My dissertation work was focused to characterize three members of the Kinesin superfamily in vitro. Kinesins are required in the cell for the correct localization and directed transport of proteins, DNA, RNA and cellular organelles. The three molecular motors of the kinesin superfamily studied here are Kar3Cik1, Kar3Vik1 and Nod. These three kinesins are unconventional ....

Tbx6 was shown to be a T-box transcription factor expressed in the primitive streak and presomitic mesoderm of the developing mouse embryo; null mutations in Tbx6 resulted in ectopic neural tube formation in place of posterior somites and embryonic lethality. However nothing was known about expression, transcriptional activity, or downstream targets of Tbx6 protein. Usi....

Maternal-fetal conflicts, specifically court-ordered Cesarean sections, are explored from a legal and ethical perspective. An increase in technology, combined with the rise of bioethics, the respect for autonomy in medical decision-making, and the legal doctrine of informed consent have created an atmosphere in which conflicts may occur between the pregnant woman and he....

Hikikomori, a phenomenon which exists to date mostly in Japan, are people who seclude themselves in their bedrooms for an extended period of time and reject most forms of contact with the outside world. These are usually males and young people in their twenties who may comprise nearly a million Japanese citizens. Since Japanese and foreign media as well as scholars expr....

This thesis studies the perceived tension between classes in contemporary urban China using the 1992 urban survey data. By investigating people¡¯s class identification and perceived class tension, I find that middle class identification exists widely in urban Chinese society and the perceived class tension is not strong enough to threaten the existing political regime....

This study examines musical and social processes in American popular music through the creative life of Pittsburgh born jazz guitarist Jimmy Ponder. I contextualize Ponders technical and conceptual approaches with a historical analysis of developments in jazz during the mid-20th century. In examining intersections between jazz and other popular forms of music during the....

The actin cytoskeleton is essential for a vast array of cellular processes and behaviors including migration, cell division, cell adhesion, intracellular trafficking, and maintenance of cell shape. Regulation of cytoskeletal dynamics is achieved through the actions of a diverse group actin-binding proteins. The actin-binding protein Apxl, is a member of the Shroom prote....

The electron transfer initiated cyclization (ETIC)/enol ether cleavage reaction has been developed in the Floreancig group as a mild and selective method for the formation of substituted tetrahydropyran rings systems, which are common in natural products. Reactions untilizing the initial substrate result in a methyl ketone substituted tetrahydropyran ring, however the ....
