How Well Do Doodle Polls Do?, Danya Alrawi, Barbara M. Anthony, Christine Chung

Computer Science Faculty Publications

Web-based Doodle polls, where respondents indicate their availability for a collection of times provided by the poll initiator, are an increasingly common way of selecting a time for an event or meeting. Yet group dynamics can markedly influence an individual’s response, and thus the overall solution quality. Via theoretical worst-case analysis, we analyze certain common behaviors of Doodle poll respondents, including when participants are either more generous with or more protective of their time, showing that deviating from one’s “true availability” can have a substantial impact on the overall quality of the selected time. We show perhaps counter-intuitively that being …

Synthesis Of Porous Manganese Oxides With Unsaturated Alcohols And Subsequent Characterization And Catalytic Activity, Chrismary De La Cruz

Chemistry Honors Papers

Porous manganese oxides have been synthesized using unsaturated alcohols (allyl alcohol and propargyl alcohol) as reducing agents in a redox reaction with KMnO4 in the presence of butyric acid. Materials have an approximate MnO2 stoichiometry and surface areas of 280 m2/g for materials made with allyl alcohol and 260 m2/g for those made with propargyl alcohol. Materials also showed a good deal of monodispersity, with the materials made from allyl alcohol having an average diameter of 156 nm± 61 nm. The materials made with propargyl alcohol had an average diameter of 143 nm ±49 nm.

Previously, highly monodisperse porous spheres …

Spatial Variation In Characterized Buried Soils And Legacy Sediments Of The Northeast Usa, Anna Marshall

Environmental Studies Honors Papers

The role of historical mill dams in transforming river systems, especially throughout New England and the mid-Atlantic Piedmont regions of the United States has recently emerged as a topic of debate amongst the scientific community. In both physiographic provinces, large postsettlement alluvium “legacy” deposits originating from colonial-era deforestation, agriculture, and ongoing hillslope land-use disturbances characterize the floodplains. Furthering land-use impacts, water-powered milling from the late 17th to early 20th century was historically intensive throughout Southeastern New England and Pennsylvania, aiding in the floodplain storage of legacy deposits behind mill dams. These geologically recent legacy sediments overlay comparatively organic-rich, pre-colonial buried …
