Show moreThis study was designed to determine the effects of curriculum specific computer aided instruction on student achievement in a College Algebra course. Curriculum specific software is microcomputer software which provides both computerized instruction and practice for each topic in the accompanying textbook and is now available for many college mathematics texts. Using methods outlined by Diem (1982) in a previous study, College Algebra students were randomly assigned to one of four groups. Six hypotheses were formulated and tested by comparing both post-test scores and growth quotients for various appropriate groups. At the.05 level of significance the following hypotheses were rejected: There is no significant difference in achievement in learning mathematics between College Algebra students who study linear inequalities using curriculum specific microcomputer drill and practice with traditional lecture and College Algebra students who study linear inequalities using a traditional lecture-homework approach. There is no significant difference in achievement among those receiving curriculum specific microcomputer aided instruction as a result of students' score on the pretest, whether placed in the upper, middle, or lower third of the pretest scores. Implications of the study included the following: (1) The use of curriculum specific computerized drill and practice can significantly increase the mathematics achievement of those students receiving a traditional lecture. (2) There is a significant relationship between a student's pretest score and their level of success when using curriculum specific microcomputer aided instruction. Recommendations for further study included the following: (1) Replication of this experiment investigating different factors such as: (a) Differences related to age, (b) attitude toward computer aided instruction, (c) type of text and software, and (d) differences related to previous computing experience. (2) Research which compares various forms of curriculum specific drill and practice. (3) Development of computerized tutorials which significantly increase student achievement.

The purpose of this study is to determine the best time variables for the application of sediment elevation tables (SET) in high-energy areas. The SET is a reliable ecological method of determining the rates of sedimentation in coastal environments.

Show moreThe purpose of this study is to determine the best time variables for the application of sediment elevation tables (SET) in high-energy areas. The SET is a reliable ecological method of determining the rates of sedimentation in coastal environments. Typically, the SET is used in low-energy environments such as swamps, marshes, and mangrove forests. Very little methodology exists for the use of SET measurements in a high-energy environment. Because SET measurements may not distinguish elevational changes between subsurface activity or sediment accretion, we complimented them with horizon marker tile measurements. These target surface accretion of sediment and offer a broader spatial range for measurement. We compare temporal variation in sediment dynamics using SET and HM measurements. Monthly time scales are of greater use for studying both variation and accretion/subsidence in high-energy areas while longer time scales may contain gaps in understanding sediment dynamics due to episodic events such as storms.

Abstract/Description
-
Many marine organisms possess endosymbiotic dinoflagellates called zooxanthellae. Bleaching is the loss of zooxanthellae, but bleached hosts can be repopulated. Little is known about how repopulation is controlled. The sea anemone Aiptasia pallida was used to study the effects of feeding on repopulation. Two groups of aposymbiotic anemones were reinfected with algae from symbiotic clones. One group was fed and the other starved, and counts of algae within each anemone were made at 3 day...
Show moreMany marine organisms possess endosymbiotic dinoflagellates called zooxanthellae. Bleaching is the loss of zooxanthellae, but bleached hosts can be repopulated. Little is known about how repopulation is controlled. The sea anemone Aiptasia pallida was used to study the effects of feeding on repopulation. Two groups of aposymbiotic anemones were reinfected with algae from symbiotic clones. One group was fed and the other starved, and counts of algae within each anemone were made at 3 day intervals for 6 weeks. The experiment was repeated, and results showed that the rate of algal growth did not differ between fed and starved groups. However, starved anemones reached plateau more quickly and lost algal cells after plateau was reached, whereas fed anemones contained more algae and protein. This suggests that starved anemones can support an algal population initially, but cannot maintain it. Space and nutrients are implicated in having a limiting effect on maintenance of symbionts.

Using computer simulation, the reaction of the Morpheus when it impacts the dock is explored and the results of at sea testing (the collision of the vehicle and the dock) is discussed. A stinger strength analysis of the docking components is included and finally, suggestions for future work including modifications of the existing dock as well as another docking scheme are presented.

Abstract/Description

Bleaching of reef corals and other cnidarians symbiotic with zooxanthellae can be attributed to the stress response of the host, algae or both. To determine if zooxanthellae are involved in the bleaching process, I infected a single strain of sea anemone, Aiptasia pallida with zooxanthellae from different hosts. I measured expulsion of the algae from the host during 24-hour incubations at 25, 32 and 34C, as well as photosynthetic rates at these temperatures. Photosynthesis and expulsion of...
Show moreBleaching of reef corals and other cnidarians symbiotic with zooxanthellae can be attributed to the stress response of the host, algae or both. To determine if zooxanthellae are involved in the bleaching process, I infected a single strain of sea anemone, Aiptasia pallida with zooxanthellae from different hosts. I measured expulsion of the algae from the host during 24-hour incubations at 25, 32 and 34C, as well as photosynthetic rates at these temperatures. Photosynthesis and expulsion of zooxanthellae were inversely and directly proportional to elevated temperatures, respectively. Photosynthesis and expulsion of zooxanthellae isolated from Condylactis gigantea showed the greatest sensitivity to elevated temperature when compared to other zooxanthellae tested. These results suggest that zooxanthellae have a function in the bleaching process and that this function may be related to their photosynthetic response. Thus, the differential tolerance of zooxanthellae to stress could partly explain the spatial variability characteristic of coral-bleaching episodes.

Show moreCoral bleaching involves the loss of symbiotic algae (zooxanthellae) from reef corals and other cnidarians during periods of environmental stress, particularly elevated temperature. In this study the thermal bleaching responses of the zoanthid Palythoa caribaeorum from three populations along the southeast coast of Florida were compared. Winter (2002--2003) and summer (2003) samples from three geographically separate sites were exposed to increased temperatures and the loss of zooxanthellae was measured. Zooxanthellae populations were sampled and identified using PCR-DGGE. The results showed that samples of P. caribaeorum from reefs that experience smaller annual thermal ranges released the most zooxanthellae. Seasonal comparisons revealed winter samples experienced a greater amount of zooxanthellae loss than summer samples. P. caribaeorum was found to harbor two genetic strains of zooxanthellae, C1 and D1a. Colonies either contained monotypic populations of these, or a combination of both.

Show moreSouth Florida is at the frontlines of climate change impacts. Facing increases in heat waves, flooding, and intensity of storms, climate change has direct detriments on the residents of this region. This research examines the evidence of Climate Change Anxiety (CCA) within Broward, Miami-Dade, Monroe, and Palm Beach counties. Using the CCA instrument developed by Susan Clayton and Bryan Karazsia in 2020, this study replicates analyses of variables conducted in prior research on the national level. This research found South Floridians are experiencing moderate levels of anxiety caused by climate change. Additionally, significant relationships exist between CCA and newly examined variables such as family situations, politics, and sociological perceptions. Sociological perceptions such as identities described in Dan Kahan’s Cultural Cognition Theory help us understand how having different views of society and life may alter how an individual is affected by CCA.
