Technology literacy is defined as the ability to operate hardware and software (computer literacy), conduct effective research for and then evaluate digital content for accuracy and merit (internet and information literacy), and digitally communicate effectively(digital media literacy). …

Could Neuro-Phenomenology Deepen An Interpretative Phenomenological Analysis Of Seizure Consciousness Drawings, Valerie Featherstone, Peter Campion, Anna Sandfield

The Qualitative Report

This article proposes a methodological stance, an Interpretative Phenomenological Analysis (IPA) of participants’ drawings as one that is useful for research into people’s experiences of seizure consciousness. Using empirical examples located in an original, larger study, this article offers a rationale for, and illustrates the analytic potential of, this combination. It also considers that elicitation interviewing techniques and methods from the field of neuro - phenomenology could take this work further in terms of deepening the analysis by reaching people’s pre - reflexive conscious experiences. This theoretical and practical combination has the potential to develop this work significantly.

Students’ Perceived Utility Of Precision Taught Calculus, Rebecca- Anne Dibbs, David Glassmeyer, Wafa Yacoub

The Qualitative Report

The last decade of calculus research has showed students learn best when lecture is supplemented with thoughtful use of technology and group work; however, educators are given little direction of how they are to balance the already full first semester calculus class. Precision teaching is an instructional model that employs formative assessment to provide information on what topics are understood by students as well as indicate troublesome concepts. With this information, the instructor can adjust class time accordingly by incorporating supplemental activities most beneficial to students. The purpose of this interview study was to explore the perceived utility of precision …

Robinson Point, Belize: An Important Foraging Ground For Endangered Sea Turtles In The Western Caribbean Sea, Linda Searle

HCNSO Student Theses and Dissertations

Anecdotal reports, flipper tag returns, satellite migration paths, and above-water and net surveys have identified an important foraging area for sea turtles in the Robinson Point area, 12 kilometers southwest of Belize City. Visual observations confirmed that sea turtles were actively foraging at Robinson Point. Sixteen 30 minute visual observations from stationary and drifting boats made 132 sea turtle sightings from October 2007 through January 2008, with a maximum of 40 sightings made in one survey. In-water capture methodology tested the traditional turtle net, which captured 14 turtles in 63 sets for a success rate of only 22%. There were …

Five Vignettes: Stories Of Teacher Advocacy And Parental Involvement, Adrienne C. Goss

The Qualitative Report

Qualitative research can, and sometimes should, utilize fictional representations, particularly when attempting to connect to and collaborate with communities outside of the academy. This work utilizes an arts - informed methodology of representation to communicate the importance and potential consequences of teacher advocacy and parental involvement. Specifically, I use fiction as a mode of representing the interview data that my research participant and I generated. After analyzing the data using grounded theory methods, I chose to represent the data with five vignettes. Vignette 1 introduces the reader to Ms. Abeni, a public school teacher who is passionate about educating every …

Species Composition And Reproductive Strategies Of Commensal Synalpheus Shrimp (Decapoda:Alpheidae) Occupying The Sponges Spheciospongia Vesparium And Spongia Sp. Of The Florida Reef Tract, Brittnee Nicole Barris

HCNSO Student Theses and Dissertations

Synalpheus shrimp species of the gambarelloides group are the only marine organisms displaying the highest level of social functioning, eusociality. Their social hierarchies are equally complex compared to the reproductive abnormalities that have been recently discovered. For instance, snapping shrimp of the genus Synalpheus were thought to be gonochoric, i.e. developing as independent sexes, until scanning electron microscopy studies revealed intersexed gonopores in several species. This project analyzed both the species composition, and accompanying reproductive structures, of Synalpheus spp. (Caridea: Alpheidae) comprised of densely aggregating communal and pair-living colonies in the Florida Keys, Florida.

Colonies of pair-living and communal Synalpheus …

Although reef degradation is currently occurring at alarming rates, there is hope for the future of coral reef health. It is proven that humans have a large effect on the current health of coral reefs. This thesis aims to determine how marine scientists and educators can best influence the general public to affect behaviors to improve reef health. To do this involves taking analyzing the many effects of human …

Determining The Extent And Characterizing Coral Reef Habitats Of The Northern Latitudes Of The Florida Reef Tract (Martin County), Brian K. Walker, David S. Gilliam

Marine & Environmental Sciences Faculty Articles

Climate change has recently been implicated in poleward shifts of many tropical species including corals; thus attention focused on higher-latitude coral communities is warranted to investigate possible range expansions and ecosystem shifts due to global warming. As the northern extension of the Florida Reef Tract (FRT), the third-largest barrier reef ecosystem in the world, southeast Florida (25–27° N latitude) is a prime region to study such effects. Most of the shallow-water FRT benthic habitats have been mapped, however minimal data and limited knowledge exist about the coral reef communities of its northernmost reaches off Martin County. First benthic habitat mapping …

Tracking Transmission Of Apicomplexan Symbionts In Diverse Caribbean Corals, Nathan L. Kirk, Raphael Ritson-Williams, Mary Alice Coffroth, Margaret W. Miller, Nicole D. Fogarty, Scott R. Santos

Marine & Environmental Sciences Faculty Articles

Symbionts in each generation are transmitted to new host individuals either vertically (parent to offspring), horizontally (from exogenous sources), or a combination of both. Scleractinian corals make an excellent study system for understanding patterns of symbiont transmission since they harbor diverse symbionts and possess distinct reproductive modes of either internal brooding or external broadcast spawning that generally correlate with vertical or horizontal transmission, respectively. Here, we focused on the under-recognized, but apparently widespread, coral-associated apicomplexans (Protista: Alveolata) to determine if symbiont transmission depends on host reproductive mode. Specifically, a PCR-based assay was utilized towards identifying whether planula larvae and reproductive …

Prototype Modeling Vs. Item Response Theory – A Paradigm Shift For Measurement Professionals, Joseph Yeager, Linda Sommer, Juliette Faughnan, Christophe Geerkens

The Qualitative Report

In science, the usual research mode is to discover cause - and - effect mechanisms operating behind superficial reality. Aviation, for example, uses prototype modeling to develop improved aircraft from one generation to the next. In stark contrast to prototype modeling’s search for causal mechanisms, assessment technologies remain dominated by probability strategies — which is why psychological assessment lags behind the hard sciences. A major difference in results exists between inferences produced through item response theory versus the cause - effect prototyping strategies of aerospace and other techno - savvy industries. Parallel to aerospace strategies, systems analysis of language, using …

Allied Health Students’ Perceptions Of Class Difficulty: The Case Of Undergraduate Human Anatomy And Physiology Classes, Diana Sturges, Trent Mauner

Migratory Patterns And Habitat Use Of The Sand Tiger Shark (Carcharias Taurus) In The Western North Atlantic Ocean, Shara Marie Teter

HCNSO Student Theses and Dissertations

Large population declines for sand tiger sharks (Carcharias taurus) in parts of its global range are well documented, resulting in a strong need for biologically informed conservation and management measures. Although sand tigers in the western North Atlantic have been listed as a Species of Concern by the US government since 1997, details of their seasonal migratory movements and especially vertical habitat use patterns along the US East Coast are limited. Understanding these movement patterns is vital to reducing fishery-related mortality of these sharks and informing other management efforts aimed at recovery of their stocks in the US Atlantic. …

Shared Mycobacterium Avium Genotypes Observed Among Unlinked Clinical And Environmental Isolates, M. Ashworth Dirac, Kris M. Weigel, Mitchell A. Yakrus, Annie L. Becker, Hui-Ling Chen, Gina Fridley, Arthur Sikora, Cate Speake, Elizabeth D. Hilborn, Stacy Pfaller, Gerard A. Cangelosi

Chemistry and Physics Faculty Articles

Our understanding of the sources of Mycobacterium avium infection is partially based on genotypic matching of pathogen isolates from cases and environmental sources. These approaches assume that genotypic identity is rare in isolates from unlinked cases or sources. To test this assumption, a high-resolution PCR-based genotyping approach, large-sequence polymorphism (LSP)-mycobacterial interspersed repetitive unit–variable-number tandem repeat (MIRU-VNTR), was selected and used to analyze clinical and environmental isolates of M. avium from geographically diverse sources. Among 127 clinical isolates from seven locations in North America, South America, and Europe, 42 genotypes were observed. Among 12 of these genotypes, matches were seen in …

A Pre-Zygotic Barrier To Hybridization In Two Con-Generic Species Of Scleractinian Corals, Andrew H. Baird, Vivian R. Cumbo, Joana Figueiredo, Saki Harii

Marine & Environmental Sciences Faculty Articles

Hybridization is often cited as a potential source of evolutionary novelty in the order Scleractinia. While hybrid embryos can be produced in vitro, it has been difficult to identify adult hybrids in the wild. Here, we tested the potential for hybridization between two closely related species in the family Fungiidae. We mixed approximately 5000 eggs of Ctenactis echinata with sperm from C. crassa. No hybrid embryos were produced. This observation adds to a growing body of evidence for pre-zygotic barriers to hybridization in corals and challenges the claim that hybridization is a major source of evolutionary novelty …

Modeling The Potential Spread Of The Recently Identified Non-Native Panther Grouper (Chromileptes Altivelis) In The Atlantic Using A Cellular Automaton Approach, Matthew W. Johnston, Samuel J. Purkis

Marine & Environmental Sciences Faculty Articles

The Indo-pacific panther grouper (Chromileptes altiveli) is a predatory fish species and popular imported aquarium fish in the United States which has been recently documented residing in western Atlantic waters. To date, the most successful marine invasive species in the Atlantic is the lionfish (Pterois volitans/miles), which, as for the panther grouper, is assumed to have been introduced to the wild through aquarium releases. However, unlike lionfish, the panther grouper is not yet thought to have an established breeding population in the Atlantic. Using a proven modeling technique developed to track the lionfish invasion, presented is the first …

Vertical Ecology Of The Pelagic Ocean: Quantified Patterns And New Perspectives, Tracey Sutton

Marine & Environmental Sciences Faculty Proceedings, Presentations, Speeches, Lectures

Applications of acoustic and optical sensing and intensive, discrete-depth sampling, in concert with collaborative international research programs, have substantially advanced our knowledge of pelagic ecosystems in the 17 years since the last Deep-water Fishes FSBI Symposium. Although the epipelagic habitat is the best-known, and remote sensing and high-resolution modeling allow near-synoptic investigation of upper layer biophysical dynamics, ecological studies within the mesopelagic and deep-demersal habitats have begun to link lower and upper trophic level processes. Bathypelagic taxonomic inventories are far from complete but recent projects (MAR-ECO and CMarZ, supported by the Census of Marine Life program) have quantitatively strengthened distribution …

Length Structure Of Deep-Pelagic Fishes Sheds New Light To Their Life Histories, M. Heino, David S. Boukal, Tone Falkenhaug, Uwe Piatkowski, F. M. Porteiro, Tracey Sutton

Marine & Environmental Sciences Faculty Proceedings, Presentations, Speeches, Lectures

Here we use a new technique to study life history variation in deep-pelagic fishes from a mid-ocean ridge system. Shape of length distribution in a population is to a significant extent determined by the degree to which an average individual approaches its asymptotic maximum size. Analysing the material from the pelagic trawl hauls taken during the 2004 Mar-Eco expedition along the northern Mid-Atlantic Ridge, we show that length distributions in many deep-pelagic fish species are characterised by negative skew (the left tail of the distribution is longer). In other words, a large proportion of individuals had a size close to …

Distribution Of Parasitic Isopods On Caridean Shrimp In South Florida Seagrass Beds, Sarah A. Briggs

HCNSO Student Theses and Dissertations

Caridean shrimp are a prominent element of seagrass faunal communities and play an important role in the energy transfer between trophic levels. They are a food source for other organisms and play an integral role in the ecosystem by feeding on algae and assisting with the breakdown of organic matter. Carideans are also fundamental to the marine fishery industry in that they are a food source for potentially valuable juvenile commercial fish. Ectoparasitic isopods (Cymothoida: Bopyridae) that infest caridean shrimps decrease the energy level of the shrimp, resulting in slower reaction time, greater predation rate, slower growth rate, and/or reduced …

Identification Of Beryllium-Dependent Peptides Recognized By Cd4+ T Cells In Chronic Beryllium Disease, Michael T. Falta, Clemencia Pinilla, Douglas G. Mack, Alex N.

Chronic beryllium disease (CBD) is a granulomatous disorder characterized by an influx of beryllium (Be)-specific CD4+ T cells into the lung. The vast majority of these T cells recognize Be in an HLA-DP–restricted manner, and peptide is required for T cell recognition. However, the peptides that stimulate Be-specific T cells are unknown. Using positional scanning libraries and fibroblasts expressing HLA-DP2, the most prevalent HLA-DP molecule linked to disease, we identified mimotopes and endogenous self-peptides that bind to MHCII and Be, forming a complex recognized by pathogenic CD4+ T cells in CBD. These peptides possess aspartic and glutamic acid residues at …
