Teaching in the Collaborative Virtual Learning Environment of Second Life: Design Considerations For Virtual World Developers
(2012-02-14)
Educators are seeking ways to better engage their students including the use of collaborative virtual learning environments (CVLEs). Some virtual worlds can serve as CVLEs as the advent of Second Life has created particular ...
An Improved Lagrangian Relaxation Method for VLSI Combinational Circuit Optimization
(2012-02-14)
Gate sizing and threshold voltage (Vt) assignment are very popular and useful techniques in current very large scale integration (VLSI) design flow for timing and power optimization. Lagrangian relaxation (LR) is a common ...
Fish Assemblage and Food Web Structure in Whedos (Shallow Floodplain Habitats) of the Oueme River, West Africa
(2012-10-19)
In the Oueme River, a lowland river in Benin, Africa, artificial ponds constructed in the floodplain (whedos) are colonized during the high-water period by a presumably random sample of fishes from the river channel. As ...
Experimental and Theoretical Investigations of Anion-pi Interactions Metallacyclic Architectures of First-Row Transition Metals and N-Heteroaromatic Ligands
(2012-07-16)
Research into anion-pi interactions has shifted from attempts to establish the legitimacy of the interaction to the incorporation of anion-pi interactions into supramolecular architectures. The research discussed in this ...
Effects of Water Content and Alumino-Silicate Sources on the Structure and Properties of Geopolymers
(2012-10-19)
Geopolymers (GPs) are a special class of inorganic polymers with unique properties. Their 3-D amorphous structure and properties are often attributed to SiO2/Al2O3 molar ratios. However; contradictory results reported in ...
Regulation of Branching by Phytochrome and Phytohormones
(2012-07-16)
Light is the fundamental source of energy and information throughout the plant life cycle. Light signals regulate plant architecture and branching, key processes that determine biomass production and grain yield. Low red ...
The Impact of a Forest Pathogen on the Endangered Golden-cheeked Warbler
(2012-07-16)
Oak wilt is a fatal disease of oaks caused by the fungus Ceratocystis fagacearum. Loss or degradation of habitat due to the disease may negatively affect the federally endangered golden-cheeked warbler (Setophaga chrysoparia). ...
Voseo to Tuteo Accommodation among Two Salvadoran Communities in the United States
(2011-08-08)
This study documents and accounts for maintenance and change in dialectal features of Salvadoran Spanish in the United States, especially voseo, as opposed to tuteo, terms signifying the use of the second person singular ...
Essays on the Relationship of Competition and Firms' Price Responses
(2012-02-14)
This dissertation investigates the relationship of competition and firms' price responses, by analyzing: i) whether new entry reduces price discrimination, ii) when incumbents reduce price discrimination preemptively in ...
Improved Algorithms for Discovery of Transcription Factor Binding Sites in DNA Sequences
(2012-02-14)
Understanding the mechanisms that regulate gene expression is a major challenge in biology. One of the most important tasks in this challenge is to identify the transcription
factors binding sites (TFBS) in DNA sequences. ...
