This manuscript describes the role of non-classical hydrogen bonds (NCHBs), specifically C–H···O interactions, in modern synthetic organic transformations. Our goal is to point out the seminal examples where C–H···O interactions have been invoked as a key stereocontrolling element and to provide predictive value in recognizing future and/or potential C–H···O interactions...
Ideal values of bond angles and lengths used as external restraints are crucial for the successful
refinement of protein crystal structures at all but the highest of resolutions. The restraints in
common usage today have been designed based on the assumption that each type of bond or
angle has a...
Effects of climate change, retreating glaciers, and changing storm patterns on debris flow hazards concern
managers in the Cascade Range (USA) and mountainous areas worldwide. During an intense rainstorm in
November 2006, seven debris flows initiated from proglacial gullies of separate basins on the flanks of Mount
Rainier. Gully heads...
Debris flows, which occur in mountain settings worldwide, have been particularly damaging in the glaciated basins flanking the stratovolcanoes in the Cascade Range of the northwestern United States. This thesis contains two manuscripts that respectively investigate the (1) initiation processes of debris flows in these glaciated catchments, and (2) debris...
Floods are major disturbance events for riverine ecosystems, directly and indirectly impacting organisms and their habitat. In this study I investigated the role of riverine floods and flow alteration in regulating aquatic macroinvertebrate population and community structure. I examined this problem using a variety of methods: a meta-analytic review of...
Because studies of forestry effects on wetlands have been so infrequent in the Pacific Northwest, each section in this report drew heavily from studies of forestry impacts to streams and riparian zones. After assembly and synthesis, that information was extrapolated, mostly in the form of hypotheses, to the very different...
Steven Universe, a relatively new show from Cartoon Network, explores an unexpectedly complex understanding of gender through their main protagonists. Utilizing Judith Butler’s work on gender performativity and doing gender, as well as Daniel Dennett’s conception of the self as a theorist’s fiction, and Alexander Weheliye’s understanding of power and...
Climate changes in the Pacific Northwest, USA, may cause both retreat of alpine glaciers and increases in the frequency and magnitude of storms delivering rainfall at high elevations absent significant snowpack, and both of these changes may affect the frequency and severity of destructive debris flows initiating on the region's...
My work on computing complex catalyzed organic transformations reveals that only a few subtle chemical factors, e.g. non-classical hydrogen bonding, (hyper)conjugation and steric effects, common across different catalyst manifolds are critical for catalysis and selectivity. Rational manipulation and exploitation of these factors has led to improved catalyst designs, which has...
As part of a larger project funded by the Joint Fire Science Program, this annotated bibliography and accompanying subject area guide were created to support development of a compendium of social science research findings from 2000 – 2010 related to fire-adapted communities. In total, 242 articles were selected for analysis.
