Histopathological Assessment And Comparison Sedimentation And Phosphate Stress On The Staghorn Coral, Acropora Cervicornis, Erin Christine Hodel

HCNSO Student Theses and Dissertations

Traditional coral reef monitoring efforts lack assessment of coral health at tissue and cellular levels. This thesis investigated tissue, cellular, and gross morphological responses of the Caribbean staghorn coral, Acropora cervicornis, to elevated sedimentation and phosphate using state-of-the-art histological techniques. Branch fragments of A. cervicornis were collected offshore Broward County, FL, acclimated for 12 weeks, subjected to a 4-week experimental period, and given a 1-week recovery period in laboratory aquaria. Treatments consisted of high doses (200 mg cm^-2 day^-1) of sedimentation (S), phosphate (4 μM) (P), and a combination of these two (S + P), in …

Performance Measurement For The E-Government Initiatives: A Comparative Study, Willy C. Isaac

CCE Theses and Dissertations

The main objective of performance measurement in public organizations is to support better decision-making by management, leading to improved outcome for the community, and to meet external accountability requirements. There are different performance measurement models to measure the e-Government initiatives and different studies differ in identifying the key factors and measurement indicator. Many measurement instruments take a too simplistic view and focus on measuring what is easy to measure. Much challenge faced by the existing e-Government studies is understanding what citizens, businesses and government agencies wants and how to measure the return on government's Internet investment. Government administrations, international organizations …

Measuring The Effect Of E-Learning On Job Performance, Heidi Kramer

CCE Theses and Dissertations

E-learning is becoming a leading delivery method in workplace-learning settings across organizations of various sectors and of varying sizes. The ultimate goal is to drive business results. Managers need to provide evidence of a positive impact on corporate strategy and investment objectives. If the business goal cannot be identified, there should be a query on why it is there in the first place. Transfer of the knowledge learned in the training session to the work situation is not built into most skills training delivery, especially those provided through e-learning. The outcomes and the effects of training on job performance are …

Measuring Factors That Influence The Success Of E-Government Initiatives, Ronnie Park

CCE Theses and Dissertations

The success of e-government initiatives is contingent upon its citizens ' willingness to use the services. Citizens are more likely to use e-government services if they believe that they get better value than from the conventional government services. Understanding how citizens value e-government services is critical to the success of these initiatives. This study utilizes two concepts from the field of decision analysis. These are mean-ends chains and value-focused thinking. The research that follows describes the development of a model to identify factors that influence value judgments of citizens.

Based on the data of 21 0 responses from e-government service …

Painting The Voice: Weblogs And Writing Instruction In The High School Classroom, Marilyn V. Olander

CCE Theses and Dissertations

Writing is a complex cognitive skill, a technology for capturing speech whose forms and conventions began in the dawn of civilization and were in place and stable by the Middle Ages. Writing and reading are the foundation of literacy, fundamental to success in school and in the adult world. No comprehensive theory of composition guides the teaching of writing, although historically two approaches have been favored: writing as a skill acquired through the memorization and recognition of principles of grammar and usage, and more recently, writing as a process of recursive strategies of pi arming, drafting, revising, editing, and publishing. …

An Analysis Of It/Is Offshore Outsourcing: Educator Perspectives, Martin H. Bagaya

This process of offshore outsourcing to overseas locations was perceived to have consequences on IT/IS student enrolment at U.S. universities.

The objective of this study was to identify administrators' responses to reduced IT/IS student enrolments. The majority of ITIIS college administrators have concerns about offshore outsourcing, and is perceived to reduce …

Electronic Performance Support For E-Learning Analysis And Design, Thomas W. Jury

CCE Theses and Dissertations

Corporate instructional designers often follow an instructional systems design (ISD) process to plan, create, and implement training programs. Increased demand for elearning as a replacement or addition to classroom training means that, in the current corporate environment, instructional designers are called upon to produce a wide variety of instructional formats and have to make more decisions during the ISD process.

E-learning is evolving into a total performance improvement solution rather than simply as a means to delivering distance training and consequently, in an effort to achieve business goals, many corporations are turning to it as a cost effective way to …

Comparison Of Fish Assemblages Between Mitigation Boulder Reef And Neighboring Natural Hardbottom In Broward County, Florida, Usa, Jessica A. Freeman

HCNSO Student Theses and Dissertations

A beach renourishment project was initiated in May 2005 and completed in February 2006 to restore 11.1 km of shoreline in Broward County, Florida, USA. For mitigation of predicted nearshore hardbottom burial, a boulder reef totaling 3.6 ha was deployed in 2003. To examine the replacement value of the mitigation relative to fishes, this study compared fish assemblages on boulder reef to those on adjacent natural hardbottom. Twenty-five natural hardbottom sites and twenty-five boulder reef sites were surveyed six times between March 2005 and August 2007. Two non-destructive visual census methods, a transect count (30 m long x 2 m …

Surface Associated Amoebae On The Ctenophore, Mnemiopsis Sp., Connie S. Versteeg

HCNSO Student Theses and Dissertations

Previous work by Moss et al. (2001) reported surface associated protists on the ctenophore Mnemiopsis sp. They frequently observed the ciliate Trichodina ctenophorii and a Flabellula-like amoeba attached to the comb plate surface. They noted that the ciliate and the amoeba were found on the subsagittal, subtentacular, and the auricular comb plates. The amoeba had a maximum width of about 15 μm and cells were crescent shaped. Ultrastructural evidence suggested that these protists were parasites although the exact nature of the association remained to be determined. This was the background for the present study.

The present investigation documented the …
