This paper explores the use and creative application of library metaphors. Unfortunately, the facts aren’t always able to speak for themselves. Simply stating reference statistics, gate counts, and resource circulation numbers are not persuasive narratives in and of themselves. Voice and context needs to be given to these forms of...
While metaphysical turmoil is the essential human problem in T.S. Eliot’s “The Waste Land,” “The Love Song of J. Alfred Prufrock” and “Preludes,” traditional criticism of the poems relegates the physical world to a merely rhetorical role. This thesis argues that Eliot’s use of objects in his poetry suggests they...
In Heart of Darkness and The Good Soldier, Joseph Conrad and Ford Madox Ford employ the narrative subjectivity inherent in their Impressionist technique to provide insight into the often-irrational processes through which political and individual identities are constructed through narrative.

Palms are an important component of tropical ecosystems, living alongside dicotyledonous trees, even though they have a very different growth pattern and vascular system. As monocots, vessels in palms are located within vascular bundles and, without a vascular cambium that many dicotyledonous trees possess, palms cannot add additional vessels to...
The role of science in marine policy, and environmental policy in general, is a debated topic. Currently, there is an increasing desire for transparent and participatory democracy that involves more input from local residents and other non-experts. These demands often conflict with the increasing complexity of problems and the real...
Forest surveys provide critical information for many diverse interests. Data are often collected from samples, and from these samples, maps of resources and estimates of aerial totals or averages are required.

Soils are globally significant sources and sinks of
atmospheric CO₂. Increasing the resolution of soil carbon
turnover estimates is important for predicting the response of
soil carbon cycling to environmental change. We show that
soil carbon turnover times can be more finely resolved using
a dual isotope label like the...
Tornadoes represent a unique natural hazard because of the very low probability of
occurrence, short warning times (on the order of only a few minutes), and the intense and
destructive forces imposed on engineered and non-engineered buildings. The very low-probability very high-consequence nature of a tornado strike makes designing for...
A stratigraphy-based chronology for the North Greenland Eemian Ice Drilling (NEEM) ice core has been derived by transferring the annual layer counted Greenland Ice Core Chronology 2005 (GICC05) and its model extension (GICC05modelext) from the NGRIP core to the NEEM core using 787 match points of mainly volcanic origin identified...
Surface transient storage (STS) and hyporheic transient storage (HTS) have functional significance in stream ecology and hydrology. Currently, tracer techniques couple STS and HTS effects on stream nutrient cycling; however, STS resides in localized areas of the surface stream and HTS resides in the hyporheic zone. These contrasting environments result...
Given image data of a fluid flow, the flow field, < u, v >, governing the evolution of the system can be estimated using a variational approach to optical flow. Assuming that the flow field governing the advection is the symplectic gradient of a stream function or the gradient of...
