Experiments To Maximize Growth In Captive Florida Pompano (Trachinotus Carolinus), Brian J. Hicks
Experiments To Maximize Growth In Captive Florida Pompano (Trachinotus Carolinus), Brian J. Hicks
HCNSO Student Theses and Dissertations
Florida pompano (Trachinotus carolinus) are highly prized food and sport fish indigenous to coastal areas of the southeastern United States. A commercially valuable fishery has historically existed in the Gulf of Mexico and on the South Atlantic seaboard. Efforts to economically culture Florida pompano in a captive environment were only partially successful. Four experiments were performed to explore the physical and environmental requirements of Florida pompano and other closely related species in the Family (Carangidae):
Experiment #1- Semi-natural spawning was induced with newly developed hormonal implants. to initiate and sustain semi-natural spawning in captive Florida pompano. Fish collected from the …
The Role Of The Einstein Library Of Nova Southeastern University In Meeting The Needs Of Distance Education Students, Anne K. Abate
The Role Of The Einstein Library Of Nova Southeastern University In Meeting The Needs Of Distance Education Students, Anne K. Abate
CCE Theses and Dissertations
The goal of this study was to evaluate the information needs of a selected segment of the distance learning graduate student population served by the Einstein Library at Nova Southeastern University and to propose a new model of library service based on the implementation of current and emerging technologies. Several survey instruments were developed and administered through electronic mail to students and faculty in the School of Computer and Information Sciences, the Center for Psychological Studies, and the School of Social and Systemic Studies, the Fischler Center for the Advancement of Education and the School of Business and Entrepreneurship at …
Effect Of Electronic Portfolio Assessments On The Motivation And Computer Interest Of Fourth And Fifth Grade Students In A Massachusetts Suburban School, Paul V. Montesino
Effect Of Electronic Portfolio Assessments On The Motivation And Computer Interest Of Fourth And Fifth Grade Students In A Massachusetts Suburban School, Paul V. Montesino
CCE Theses and Dissertations
A preliminary causal-comparative study was conducted in an elementary suburban school in Massachusetts to investigate the impact of electronic portfolio assessments in student's intrinsic motivation and computer interest.
The target population were two groups of fourth grade and two groups of fifth grade students for a total of 77 subjects. They were trained and introduced to electronic portfolio assessments, a program which lasted for the entire school year. The students used Hyper Studio, a multimedia software program developed and marketed by Roger Wagner Publishing, Inc.
It was the intention of the elementary school program directors and teachers that students would …
The Auditory Display In Interactive Courseware: Moving Human Factors Into Computer Education, David T. Lauret
The Auditory Display In Interactive Courseware: Moving Human Factors Into Computer Education, David T. Lauret
CCE Theses and Dissertations
The arrival of inexpensive high fidelity audio capabilities for personal computers has been accompanied by sweeping claims of enhanced educational effectiveness. Research has only served to confuse these claims with both significant and non-significant findings. This may be due partly to the single dimensional model which has been assumed when examining audio. When computer-based audio is examined as a multi-dimensional display analogous in capability and function to the more familiar visual display (computer screen), a different picture emerges. Although it is now clear that integrated audio can enhance learning, the instructional designer is still left with little guidance whether or …
A Simplified Faceted Approach To Information Retrieval For Reusable Software Classification, Victor Allen Nguyen
A Simplified Faceted Approach To Information Retrieval For Reusable Software Classification, Victor Allen Nguyen
CCE Theses and Dissertations
Software Reuse is widely recognized as the most promising technique presently available in reducing the cost of software production. It is the adaptation or incorporation of previously developed software components, designs or other software-related artifacts (i.e. test plans) into new software or software development regimes. Researchers and vendors are doubling their efforts and devoting their time primarily to the topic of software reuse. Most have focused on mechanisms to construct reusable software but few have focused on the problem of discovering components or designs to meet specific needs. In order for software reuse to be successful, it must be perceived …
The Occurrence Of Pcbs And Chlorinated Pesticide Contaminants In Bottlenose Dolphins (Tursiops Truncatus) In A Resident Community: Comparison With Age, Gender And Birth Order, Kathleen M. Kuss
HCNSO Student Theses and Dissertations
Tissue samples from twenty bottlenose dolphins from a stable, residential community of coastal dolphins in the western Gulf of Mexico were analyzed for toxic PCB congeners and chlorinated pesticides. The tissues analyzed (blubber and melon) were from known individuals in a long-term (27+ y) study that stranded and were recovered for necropsy. Substantial demographic data were available on these individuals and utilized in the analysis of maternal transfer of organochlorines to young.
The male dolphins in this study were shown to accumulate organochlorine contaminants with age. In female dolphins the organochlorine levels were found to decline with age. These …
Variability In Copepod Hatching Success: Observations On Natural Populations And Experiments On The Role Of Maternal Diet, Carol A. Burkart
Variability In Copepod Hatching Success: Observations On Natural Populations And Experiments On The Role Of Maternal Diet, Carol A. Burkart
HCNSO Student Theses and Dissertations
The objectives of this study were (1) to survey the percent hatching success of eggs produced by calanoid copepod species from a variety of ecosystems (i.e., polar, temperate, and sub-tropical), (2) to describe the relationship between egg production, hatching success of Acartia tonsa and the physical and food environments of Florida Bay, and (3) to describe the relationships between hatching success and maternal diet. In order to fulfill the first objective, an incubation system was designed to allow the monitoring of eggs at sea for extended periods of time. The second objective was addressed with a series of egg production …
