Monstrous beings, or distortions of nature, were a tangible object of fear in the medieval and early modern eras. Aristotle, as a precursor to the scientists and magical practitioners of the twelfth century or the barber-surgeons of the sixteenth century, understood monsters to be human or animal beings deformed by...
Maximum sustainable yield (MSY) has been recommended as a reference point for fisheries sustainability. However, like other reference points it is generally applied on a single-species basis. This has potentially significant biological implications in a complex multispecies fishery. MSY-based reference points also have economic implications for fisheries prosecuting the resource....
The results presented in this dissertation address a number of questions regarding late Pleistocene and Holocene ice-sheet and climate interactions, spanning disciplines involving paleoclimatology and atmospheric science. These studies use various techniques in geochemistry, climate modeling, and ice-sheet modeling to address ice- sheet response to climate and the attendant interactions...
The goals of this dissertation are centered on understanding changes in Earth surface and climate systems through the use of geologic proxies as records of past changes in these systems. Specifically, this dissertation (1) establishes a new chronology for retreat of the Ross Sea sector of the West Antarctic Ice...

The goal of dissertation research was to use geochemical, statistical and geological methods to constrain and understand climate variability over several different time scales. Specifically, I have addressed three questions regarding past climate change: (1) how does the record of Irish cirque glaciers constrain the dimensions of the Irish Ice...
The purpose of this research was to determine the effects of a
college human sexuality course upon sex knowledge, attitudes toward
sexual behaviors of non-significant others, and attitudes toward the
sexual behaviors of self and spouse. In addition, the study sought to
investigate the relationship between knowledge gain and attitude...
Clothing is wrought with symbolism. Each day when outfits are selected and worn, messages are being sent and received, categorizing the wearer. The self and the many different roles that it plays in society are important factors in determining a personal appearance. We try to reflect our internal concept of...
We review and synthesize the geologic record that
constrains the sources of sea level rise and freshwater discharge
to the global oceans associated with retreat of ice
sheets during the last deglaciation. The Last Glacial Maximum
(~26–19 ka) was terminated by a rapid 5–10 m sea
level rise at 19.0–19.5...
The ongoing retreat of glaciers globally is one of the clearest manifestations of recent global warming associated with rising greenhouse gas concentrations. By comparison, the importance of greenhouse gases in driving glacier retreat during the most recent deglaciation, the last major interval of global warming, is unclear due to uncertainties...
