A Study Of The Relationships Between End-User Information Systems Problems And Helpdesk Critical Success Factors In Higher Education, Richard Dale Parrott Jan 2005

A Study Of The Relationships Between End-User Information Systems Problems And Helpdesk Critical Success Factors In Higher Education, Richard Dale Parrott

CCAC Theses and Dissertations

In the last fifteen years, information technology (IT) customer support has increased in importance within higher education. The pervasiveness of computers and technology on the campus has allowed students, staff, and faculty to perform a multitude of tasks by controlling their own environments and setting their own priorities. Qualified professional system and user support services have lagged demand. The problem investigated in this study was end-users' satisfaction levels of the higher education helpdesk and how end-users' satisfaction levels affected a helpdesk manager's critical success factors performance and goals. In this study, the first goal was to identify the critical success …

Computer-Supported Rehabilitation Management A Case Study Of Using Virtual Reality Technology In Ambulatory Training For Post-Acute Stroke Patients, Felix O. Akinladejo Jan 2005

Computer-Supported Rehabilitation Management A Case Study Of Using Virtual Reality Technology In Ambulatory Training For Post-Acute Stroke Patients, Felix O. Akinladejo

CCAC Theses and Dissertations

This study investigated the use of virtual reality (VR) technology in ambulatory training for post-acute stroke patients, and sought to determine whether skills gained in virtual environments transfer to real-world conditions. Patients with stroke typically suffer dysfunctions that impair the complex set of motions involved in walking. The limited amount of therapy and resources offered by the current health care system does not provide the frequency and intensity of training needed for functional recovery of the walking skills in patients following stroke assaults. This study, therefore, developed and investigated an alternative intervention technique capable of providing the frequency and intensity …

Reevaluation Of Species Concepts Of Uppermost Cretaceous Unionidae (Mollusca: Bivalvia) : Hell Creek Formation, Montana, U.S.A., Marron J. Bingle Jan 2005

Reevaluation Of Species Concepts Of Uppermost Cretaceous Unionidae (Mollusca: Bivalvia) : Hell Creek Formation, Montana, U.S.A., Marron J. Bingle

Theses and Dissertations

Species are the basic units of life relative to taxonomy, and a practical definition of species is imperative to paleontology in order to promote reproducible, unambiguous criteria for accurately interpreting past species relationships. The need for a well-defined rubric for identifying species is evident in the freshwater mussel assemblage (Family Unionidae) in the Hell Creek Formation. The Hell Creek Formation unionid species were first described by Whitfield in 1903 and 1907. His descriptions were often based on differences of a single trait. In 1976, Russell reevaluated the original species descriptions, I but still based the classification of species on only …

Isotopic Tracers As Evidence Of Denitrification In The Karlsruhe Aquifer, Eben J. Spencer Jan 2005

Isotopic Tracers As Evidence Of Denitrification In The Karlsruhe Aquifer, Eben J. Spencer

Theses and Dissertations

The Karlsruhe Aquifer of north-central North Dakota has experienced considerable nitrate contamination sparking an investigation by the North Dakota State Water Commission. Certain portions of the aquifer have experienced nitrate-N concentrations of up to seven times the drinking water standard. Although contamination is evident it is possible the NO₃¯ is naturally being eliminated by denitrification, whereby bacteria reduce NO₃¯ to nitrogen gas. Evidence of denitrification may be illustrated by accelerated reduction of NO₃¯ relative to the conservative tracer Cl¯ coupled with an increase in the heavy isotopes of 15N and 18O within the NO₃¯ ion. Such an increase is not …

Numerical Modelling Of Disintegration Of Basin-Scale Internal Waves In A Tank Filled With Stratified Water, N. Stashchuk, V. Vlasenko, K. Hutter Jan 2005

Numerical Modelling Of Disintegration Of Basin-Scale Internal Waves In A Tank Filled With Stratified Water, N. Stashchuk, V. Vlasenko, K. Hutter

School of Biological and Marine Sciences

We present the results of numerical experiments performed with the use of a fully non-linear non-hydrostatic numerical model to study the baroclinic response of a long narrow tank filled with stratified water to an initially tilted interface. Upon release, the system starts to oscillate with an eigen frequency corresponding to basin-scale baroclinic gravitational seiches. Field observations suggest that the disintegration of basin-scale internal waves into packets of solitary waves, shear instabilities, billows and spots of mixed water are important mechanisms for the transfer of energy within stratified lakes. Laboratory experiments performed by D. A. Horn, J. Imberger and G. N. …
