Coastal Circulations Driven By River Outflow, Shuliang Zhang

HCNSO Student Theses and Dissertations

Variable-density, 1^1/2- and 2^1/2- layer models are used to examine the behavior of plumes resulting from a fresher outflow of transport M_r and salinity S_r into a pre-existing oceanic layer of initial thickness H₁ and salinity S₁. It is found that the plumes exhibit a variety of features depending on conditions of the outflow, the situation of the ambient ocean, and external forcing. Perhaps the most interesting feature is that the plume can flow along the upstream (to the left of the river mouth, looking seaward in the northern hemisphere) coast …

A Proposed Solution For Word-Recognition Deficit In The Computer Environment, Hyacinth Williams

CCE Theses and Dissertations

Most college students with reading disabilities have difficulty with word recognition. The purpose of this study was to use an investigator-made cue word list to increase low word recognition skills among college students while creating slides for a university curriculum using a simple presentation tool. The investigator randomly divided fourteen subjects into two groups. One group received the treatment and the other did not. Subjects received fifty minutes to complete a five-slide presentation. The investigator used four different data collection processes for data collection. Beyond this, the investigator presented the results using rank correlation. Results from this study indicated that …

The Effects Of User Interface Metaphors On The Learnability Of Computer Systems By Field Dependent And Field Independent Computer Users, Robert N. Urwiler Jr.

CCE Theses and Dissertations

This study was designed to assess the differences in the learning performance (speed and accuracy) with which field dependent and field independent subjects could complete a set of checkbook management tasks using software employing a user interface making strong use of common checkbook management metaphors versus software employing an interface adhering to a defacto industry standard-based graphical user interface design guideline. It was hypothesized that both field dependent and field independent users would complete tasks more quickly and accurately using both user interface types.

From a population of traditional and non-traditional college students, 64 individuals volunteered to participate in the …

Development And Evaluation Of Interactive Courseware For Visualization Of Graph Data Structure And Algorithms, Thomas E. Beutel

CCE Theses and Dissertations

The primary goal of this dissertation was to develop and pilot test interactive, multimedia courseware which would facilitate learning the abstract structures, operations, and concepts associated with graph and network data structures in Computer Science. Learning objectives and prerequisites are presented in an introduction section of the courseware and a variety of learning activities are provided including tutorials, animated demonstrations, interactive laboratory sessions, and self-tests. Courseware development incorporated principles and practices from software engineering, instructional design, and cognitive learning theories. Implementation utilized an easy-to-use authoring tool, NeoBook Professional (1994), to create the overall framework and the user interfaces, and Microsoft …
