"Temporal Analysis of Suspended Sediment Concentration Changes in a Proglacial Meltwater Stream, Linnébreen, Svalbard" by Kayla Nussbaum '13

Research suggests that climate change has significantly affected global environments, and that the current warming trend will continue.  Arctic environments, as particularly sensitive places to climate change, are a critical area to study. In order to quantify climate change in Arctic places, glaciologists and glacial hydrologists study the complicated dynamics of glaciers in the rapidly changing polar areas of the globe. Building off of previous work, this presentation will investigate the water discharge and suspended sediment flux patterns in a proglacial meltwater stream flowing from a glacier in Spitsbergen, Svalbard to characterize sediment storage in the proglacial system.  Suspended sediment yield changes act as sensitive indicators to monitor interactions between the glacier, climate, and landscape. This work will use statistical methods to provide a framework with which to qualitatively and quantitatively describe subseasonal forcings behind glacier melt and glacial denudation rates, and will contribute to continuing research on the Arctic’s responses to climate change. 

"Oration of the Feces: Conflicting Discourses of Participatory Post-Development in Community-Led Total Sanitation" by Shaina Kasper '13

The development community perceives the lack of toilets, freshwater sources, and hand washing stations as a public health issue – a “sanitation crisis” – to remedy with water, sanitation and hygiene initiatives. Community-Led Total Sanitation (CLTS) is participatory development within the framework of grassroots postmodern theory. While the collaborative process of CLTS incorporates community involvement, it still imposes globalized sanitation norms and thus a dominant external worldview. This paper will highlight the tension between the participatory and postmodern framing of CLTS and offer policy recommendations for improving the CLTS process.
