Introducing Vireo: an ETD Submittal and Management System for DSpace

4th International Conference on Open RepositoriesThis presentation was part of the session : DSpace User Group PresentationsDate: 2009-05-20 03:30 PM – 05:00 PMThe Texas Digital Library (TDL) is a consortium of public and private institutions from across the state of Texas; a major project in TDL is the development of a state-wide repository for managing the entire life-cycle of electronic theses and dissertations (ETDs). The Texas ETD Repository is a large effort that span multiple independent initiatives, all of which interact to support the overall task of managing ETDs in Texas. This presentation will describe Vireo, the customized submission and workflow management application that TDL developed for DSpace, and it's role within the Texas ETD Repository. We will describe its current implementation as a Manakin aspect and theme, and discuss the future plans for the application, including its release to the repository community under an open source license.Institute for Museum and Library Sciences; Texas Digital Librar

Trophic pathways supporting Arctic Grayling in a small stream on the Arctic Coastal Plain, Alaska

Thesis (M.S.) University of Alaska Fairbanks, 2015Arctic Grayling (Thymallus arcticus) are widely distributed on the Arctic Coastal Plain (ACP) of Alaska, and are one of the few upper level consumers in streams, but the trophic pathways and food resources supporting these fish are unknown. Grayling migrate each summer into small beaded streams, which are common across the landscape on the ACP, and appear to be crucial foraging grounds for these and other fishes. I investigated prey resources supporting different size classes of grayling in a beaded stream, Crea Creek, where petroleum development is being planned. The specific objectives were to measure terrestrial prey subsidies entering the stream, quantify prey ingested by Arctic Grayling and Ninespine Stickleback (Pungitius pungitius), determine if riparian plant species affect the quantity of terrestrial invertebrates ingested by grayling, and determine if prey size and type ingested were a function of predator size. Results indicated that small grayling ( 15 cm FL) foraged most heavily on stickleback. Riparian plant species influenced the quantity of terrestrial invertebrates entering the stream, however these differences were not reflected in fish diets. This study showed that grayling can be both highly insectivorous and piscivorous, depending upon fish size class, and that both aquatic and terrestrial invertebrates, and especially stickleback, are the main prey of grayling. These results highlight the importance of beaded streams as summer foraging habitats for grayling. Understanding prey flow dynamics in these poorly studied aquatic habitats, prior to further petroleum development and simultaneous climate change, establishes essential baseline information to interpret if and how these freshwater ecosystems may respond to a changing Arctic environment

STRATEGIES FOR STRENGTHENING THE GREAT PLAINS ORAL HEALTH WORKFORCE

The looming shortage of dentists in rural communities throughout the Great Plains is a well-documented concern. Access to care can be a problem, and the lack of dental care is generally most acute among those with low income, those with complex health issues, and minorities. Studies are finding that there are significant associations between poor oral health and the occurrence of systemic diseases or problems. Examples include cardiovascular disease, stroke, and preterm delivery of low-birth weight infants. The two primary diseases of the oral cavity-dental caries and periodontal disease-are not only treatable but also preventable with adequate care. The University of Nebraska Medical Center (UNMC) College of Dentistry (COD) is committed to strengthening the rural dental workforce of the Great Plains by focusing upon rural recruitment strategies, service learning educational opportunities in rural communities, and strong support for dentists who practice in remote locations. Working closely with Nebraska and neighboring states, the UNMC College of Dentistry is striving to improve the oral health and economic vitality of small communities throughout the Great Plains region

AN INCIPIENT ARMS RACE: HYPERSONIC WEAPON DEVELOPMENT IN THE UNITED STATES, CHINA, AND RUSSIA

The United States, China, and Russia are each competing to develop hypersonic weapons. Can this hypersonic weapon competition be classified as an arms race? Current literature regarding hypersonic weapons treats them as a manifestation of arms racing, but does not offer a comprehensive assessment of arms race dynamics in current hypersonic weapon development. This thesis uses traditional arms race theory and current strategic stability literature to analyze the hypersonic weapon competition and to highlight challenges the competition imposes. This thesis proposes a new arms racing category to classify the hypersonic weapon competition: an incipient arms race. It defines an incipient arms race, examines the importance of recognizing its incipiency, and raises potential problems for policymakers to consider. This thesis recommends that policymakers fully consider the impact that a full arms race would have on global strategic security prior to committing the required resources to offensive and defensive hypersonic weapon systems.Lieutenant, United States NavyApproved for public release.

A distributed programming environment for Ada

Despite considerable commercial exploitation of fault tolerance systems, significant and difficult research problems remain in such areas as fault detection and correction. A research project is described which constructs a distributed computing test bed for loosely coupled computers. The project is constructing a tool kit to support research into distributed control algorithms, including a distributed Ada compiler, distributed debugger, test harnesses, and environment monitors. The Ada compiler is being written in Ada and will implement distributed computing at the subsystem level. The design goal is to provide a variety of control mechanics for distributed programming while retaining total transparency at the code level

Deindividuation of Drivers: Is Everyone Else a Bad Driver?

Deindividuation is a psychological phenomenon that occurs when a given environment reduces the individuality or identifiability of a person. These environments may cause a psychological reduction in self-consciousness, potentially leading to violations of sociocultural norms (Festinger, Pepitone, & Newcomb, 1952; Singer, Brush, & Lublin, 1965). The present research sought to empirically test deindividuation theory among automobile drivers utilizing the anonymizing factor of observation. Participants (N = 31) used a driving simulator and were either in the observed condition or an unobserved condition. Analysis of driving data did not reveal significant results, however self-report data had some interesting trends. Though limited in scope, this research begins to shed light on deindividuation of drivers and may provide a foundation for future research

The Astro-WISE approach to quality control for astronomical data

We present a novel approach to quality control during the processing of astronomical data. Quality control in the Astro-WISE Information System is integral to all aspects of data handing and provides transparent access to quality estimators for all stages of data reduction from the raw image to the final catalog. The implementation of quality control mechanisms relies on the core features in this Astro-WISE Environment (AWE): an object-oriented framework, full data lineage, and both forward and backward chaining. Quality control information can be accessed via the command-line awe-prompt and the web-based Quality-WISE service. The quality control system is described and qualified using archive data from the 8-CCD Wide Field Imager (WFI) instrument (http://www.eso.org/lasilla/instruments/wfi/) on the 2.2-m MPG/ESO telescope at La Silla and (pre-)survey data from the 32-CCD OmegaCAM instrument (http://www.astro-wise.org/~omegacam/) on the VST telescope at Paranal.Comment: Accepted for publication in topical issue of Experimental Astronomy on Astro-WISE information syste
