A Best Practice Model For Cloud Middleware Systems, Ajith Harshana Ranabahu, E. Michael Maximilien

Kno.e.sis Publications

Cloud computing is the latest trend in computing where the intention is to facilitate cheap, utility type computing resources in a service-oriented manner. However, the cloud landscape is still maturing and there are heterogeneities between the clouds, ranging from the application development paradigms to their service interfaces,and scaling approaches. These differences hinder the adoption of cloud by major enterprises. We believe that a cloud middleware can solve most of these issues to allow cross-cloud inter-operation. Our proposed system is Altocumulus, a cloud middleware that homogenizes the clouds. In order to provide the best use of the cloud resources and make …

Context And Domain Knowledge Enhanced Entity Spotting In Informal Text, Daniel Gruhl, Meena Nagarajan, Jan Pieper, Christine Robson, Amit P. Sheth

Kno.e.sis Publications

This paper explores the application of restricted relationship graphs (RDF) and statistical NLP techniques to improve named entity annotation in challenging Informal English domains. We validate our approach using on-line forums discussing popular music. Named entity annotation is particularly difficult in this domain because it is characterized by a large number of ambiguous entities, such as the Madonna album “Music” or Lilly Allen’s pop hit “Smile”.

We evaluate improvements in annotation accuracy that can be obtained by restricting the set of possible entities using real-world constraints. We find that constrained domain entity extraction raises the annotation accuracy significantly, making an …

Effects Of Re-Grown Forest Habitat On Lemur Catta Behavior, Sophie Ackoff

Independent Study Project (ISP) Collection

This study examines the effects of re-grown forest habitat on L. catta behavior at Berenty Private Reserve in Southern Madagascar during the early wet season. Evaluation of the reforested area versus natural forest revealed significant differences in species composition and food availability. Though the re-grown forest showed signs of forest regeneration and total greater food availability, the natural forest of Malaza proved to contain more preferred food sources for L. catta. Behavioral observations were collected over eight full-day troop follows and showed significant differences in feeding behavior, activity budget, and intra-troop and inter-troop aggressions. The WELL troop in Ankoba, the …

Prevalence And Intensity Of Trypanosome Infections In Stable And Declining Populations Of Brush-Tailed Bettongs (Bettongia Penicillata), Melissa Chiasson

Independent Study Project (ISP) Collection

The brush-tailed bettong (Bettongia penicillata), or woylie, is an endemic Australian marsupial that has recently suffered a large population crash in the Upper Warren region of Western Australia. Research has shown that both the declining Upper Warren population of brush-tailed bettongs and a stable population at Karakamia Wildlife Sanctuary are infected with a novel Trypanosoma sp., and the declining Upper Warren population was found to have a higher prevalence of trypanosome infection that that of the stable Karakamia population. In this study, further work was done to see if 1) the prevalence and intensity of trypanosome infection still differed significantly …

Heat And Smoke Effects On Red Brome Soil Seed Banks, Scott R. Abella, E. Cayenne Engel

Public Policy and Leadership Faculty Research

Management of exotic plants that are annuals entails understanding and managing their soil seed banks. We completed a study of the influences of heat and liquid smoke on red brome (Bromus rubens) soil seed banks collected from Red Rock Canyon in southern Nevada as part of a collaborative fire effects monitoring effort with Bureau of Land Management - Las Vegas. We collected the samples from the 2005 Loop Fire, where we observed in a monitoring field study that exotic grasses such as red brome were relatively sparse in the first 2-3 years (which were during a dry period) following the …

Migration Dynamics Of The Northern Saw-Whet Owl In The Piedmont, Mountain, And Coastal Plain Provinces Of Virginia, Kyle E. Van Althuis

Senior Honors Theses

The Northern Saw-whet Owl (Aegolius acadicus) is a small common owl of which little is known. The saw-whet’s migration dynamics are particularly shrouded in mystery due to the secretive nature of this owl. This study examined data obtained by capturing owls with mist nets in order to better understand volume, timing, sex differences and age differences in migration in the Piedmont province of Virginia for 2002-2007. Comparative owl capture data from two other physiographic regions (Mountain and Coastal Plain) were also examined.

Migration flight volume was highest in the Mountain province and lowest in the Coastal Plain, while movements were …

Higher Education And The Society For Neuroscience: A Website Proposal That Helped Catalyze A Change In Policy, Richard F. Olivo

Neuroscience: Faculty Publications

In the spring of 2007, the Society for Neuroscience (SfN) did not include support for higher education as a priority in its strategic plan. By the spring of 2009, its priorities had changed. One catalyst for that change was a proposal for a website that would list, review, and rate resources for teaching neuroscience at the graduate and undergraduate level. The proposal was sent to and accepted by SfN Council in August 2008; by spring 2009, SfN had taken initial steps to implement it. Two documents are presented here that mark the change in policy: the website proposal, and SfN …

Differences In Leaf Traits, Leaf Internal Structure, And Spectral Reflectance Between Two Communities Of Lianas And Trees: Implications For Remote Sensing In Tropical Environments, G. Arturo Sanchez-Azofeifa, Karen Castro, S. Joseph Wright, John Gamon, Margaret Kalacska, Benoit Rivard, Stefan A. Schnitzer, Ji Lu Feng

Biological Sciences Faculty Research and Publications

Increasing dominance of lianas in many tropical forests is considered a fingerprint of global environmental change. Despite the key role they play in ecosystem functioning, lianas remain one of the least studied life forms in tropical environments. This paper contrasts leaf traits and spectral properties (400–1100 nm) of liana and tree communities from a tropical dry forest and a tropical rainforest in Panama, Central America. Differences between lianas and tree leaf traits were analyzed using spectroscopy, leaf histology and pigment extractions. Results from this study indicate that many of the biochemical, structural, and optical properties of lianas …

First Records Of Hypleurochilus Geminatus And Centropristis Philadelphica From Chesapeake Bay, Aimee D. Halvorson

Virginia Journal of Science

During the fall of 2007, Centropris philadelphica (rock seabass) and Hypleurochilus geminatus (Crested blenny) were collected from Chesapeake Bay. These captures are significant as they represent the first substantiated record of C. philadelphica from Chesapeake Bay and only the second and third validated records of H. geminatus. Additionally, the first record of H. geminatus from Chesapeake Bay was only recently recognized since the specimen had been previously misidentified as Parablennius marmoreus (seaweed blenny). The collection of seven individuals of H. geminatus in 2007, from two locations, indicates that the species may be resident within the Chesapeake Bay estuary.

Phytoplankton Blooms: Their Occurrence And Composition Within Virginia's Tidal Tributaries, Harold G. Marshall, Todd A. Egerton

Virginia Journal of Science

Sporadic algal bloom development within a 10 year monitoring program in Virginia tidal tributaries of Chesapeake Bay is reviewed. These blooms were common events, characteristically producing a color signature to the surface water, typically short lived, occurring mainly from spring into autumn throughout different salinity regions of these rivers, and were produced primarily by dinoflagellates. The abundance threshold levels that would identify bloom status from a non-bloom presence were species specific, varied with the taxon's cell size, and ranged from ca. 10 to 10⁴ cells mL^-1. Among the most consistent sporadic bloom producers were the dinoflagellates Akashiwo …

Recruitment And Retention Of Sports Officials, Peter J. Titlebaum, Nichole Haberlin, Garrett Titlebaum

Health and Sport Science Faculty Publications

A 2001 report by the National Association of Sports Officials (NASO) indicated there is likely to be a shortage of sport officials in the near future. This report also indicated that soccer and field hockey were already struggling to find officials as early as 2001. The purpose of this article is to identify researched recruitment and retention issues of sports officials; ways to retain current officials; and strategies to help recruit new officials.

Reducing The Impact Of Pcr-Mediated Recombination In Molecular Evolution And Environmental Studies Using A New-Generation High-Fidelity Dna Polymerase, Daniel J.G. Lahr, Laura A. Katz

Biological Sciences: Faculty Publications

PCR-mediated recombination can greatly impact estimates of diversity, both in environmental studies and in analyses of gene family evolution. Here we measure chimera (PCR-mediated recombinant) formation by analyzing a mixture of eight partial actin sequences isolated from the amoeba Arcella hemisphaerica amplified under a variety of conditions that mimic standard laboratory situations. We further compare a new-generation proofreading processivity-enhanced polymerase to both a standard proofreading enzyme and previously published results. Proofreading polymerases are preferred over other polymerases in instances where evolutionary inferences must be made. Our analyses reveal that reducing the initial template concentration is as critical as reducing the …
