A Modeling Of Bradford Keeney’S Ability To Gain Cooperation With Directives, Robert Musikantow

The Qualitative Report

Gaining cooperation with directives is an important aspect of psychotherapy. This paper analyzes therapeutic examples from Bradford Keeney, utilizing transcripts, videos, and the viewing of live sessions. Important factors were identified that lead to improved cooperation with therapist-generated directives. These factors are: Construct a resourceful context, compliment client while highlighting and amplifying resources, utilize resourceful naming, notice reactions and adjust, gain commitment. Each factor is illustrated with examples from transcripts of client sessions.

Flexible Gating Of Contextual Influences In Natural Vision, Odelia Schwartz

Mathematics Colloquium Series

An appealing hypothesis suggests that neurons represent inputs in a coordinate system that is matched to the statistical structure of images in the natural environment. I discuss theoretical work on unsupervised learning of statistical regularities in natural images. In the model, Bayesian inference amounts to a generalized form of divisive normalization, a canonical computation that has been implicated in many neural areas. In our framework, divisive normalization is flexible: it is recruited only when the image is inferred to contain dependencies, and muted otherwise. I particularly focus on recent work in which we have applied this approach to understanding spatial …

Fine-Grained Bacterial Compositional Analsysis Of The Port Everglades Inlet (Broward County, Fl) Microbiome Using High Throughput Dna Sequencing, Lauren M. O'Connell

HCNSO Student Theses and Dissertations

Port Everglades Inlet is one of the busiest ports in the country and is a point source of pollution to surrounding beaches and offshore corals from heavy boat traffic and urban runoff. Understanding fluctuations of bacterioplankton communities in major port inlets is important due to their impacts on surrounding marine environments. To understand annual microbial fluctuations, the 16s rRNA V4 hypervariable region was sequenced using Illumina high-throughput DNA sequencing technology. Surface samples were taken weekly for one year to generate baseline fluctuations in the microbial community. Total reads of 1.4 million were generated with a final count of 16,384 Operational …

Biodiversity And Ecological Dynamics Of Sciophilous Benthic Communities On Artificial Plates: Emphasis On Reef Sponges, Caidra Elizabeth Hassanzada

HCNSO Student Theses and Dissertations

Low light intensity habitats harbor unique sciophilous benthic communities and are a source of novel and unique sponge fauna. However, the community structure of these habitats is poorly studied to date. Thus, this study attempts to understand the composition and structure of sciophilous sponge populations in southeast Florida. Fifty limestone plates were placed on a shallow reef in Fort Lauderdale for two years (2010-2012). To identify the sponge community and their patterns over time, all plates were photographed at the end of each year. Then, samples were taken from each of the live sponge specimens observed on the plates and …

Learning From Lionfish: Modeling Marine Invaded Systems, Matthew Johnston

Mathematics Colloquium Series

Simulating marine invaded systems requires broad consideration of physical oceanographic processes, such as ocean circulation patterns and temperature, and biological traits of the invader, such as their reproductive strategy and tolerances to their environment. Through this understanding of baseline biological and oceanographic function, models can be developed in order to forecast the incursion patterns of marine invasive species - helpful both to predict their spread as well as forewarn of impacts. To facilitate this understanding, computer simulation is useful in order to quickly and efficiently assimilate large biological and oceanographic datasets into digestible products. Data derived from such simulations are …

A Scientific Basis For Regulating Deep-Sea Fishing By Depth, Jo Clarke, Rosanna Milligan, David M. Bailey, Francis Neat

Marine & Environmental Sciences Faculty Articles

The deep sea is the world’s largest ecosystem, with high levels of biodiversity and many species that exhibit life-history characteristics thatmake them vulnerable to high levels of exploitation. Many fisheries in the deep sea have a track record of being unsustainable. In the northeast Atlantic, there has been a decline in the abundance of commercial fish species since deep-sea fishing commenced in the 1970s. Current management is by effort restrictions and total allowable catch (TAC), but there remain problems with compliance and high levels of bycatch of vulnerable species such as sharks. The European Union is currently considering new legislation …

Computing Invariant Dynamics For Differential Equations: Spectral Methods, Errors, And Computer Assisted Proof, J. D. Mireles James

Mathematics Colloquium Series

The qualitative theory of dynamical systems is concerned with studying the long time behavior discrete and continuous time models such as nonlinear differential equations. The long time behavior of such models is organized by landmarks called invariant sets. For complicated nonlinear equations these invariant sets are difficult to study via pen and paper analysis, and we typically employ numerical simulations to gain insights into the dynamics. If we now think of these computer assisted insights as mathematical conjectures, then it is natural to ask how we might obtain proofs. Since the conjectures themselves originate with the computer it is not …

Southeast Florida Coral Reef Fishery-Independent Baseline Assessment, Kirk Kilfoyle, Brian K. Walker, Dana P. Fisco, Steven G. Smith, Richard E. Spieler

Marine & Environmental Sciences Faculty Reports

Reef fishes are important biologic, ecologic, and economic resources of the marine ecosystem which must be managed for sustainability. Until recently, there was no long-term monitoring program in place to assess the condition of reef fish resources of the northern Florida Reef Tract (FRT) (northern Miami-Dade, Broward, Palm Beach, and Martin counties). An assessment/monitoring plan for the northern portion of the Florida reef tract was designed through a joint cooperative effort by scientists at the University of Miami, Rosenstiel School of Marine and Atmospheric Science (RSMAS), National Oceanic and Atmospheric Administration (NOAA)-Southeast Fisheries Science Center (SEFSC) and Nova Southeastern University …

A Phylogenetic Revision Of Superfamily Himerometroidea (Echinodermata: Crinoidea), Kristian Taylor

HCNSO Student Theses and Dissertations

Superfamily Himerometroidea AH Clark, 1908 (Echinodermata: Crinoidea) (formerly Mariametroidea) is the second most speciose superfamily in order Comatulida. Although it includes some of the most common species on tropical western Pacific reefs, its phylogeny is poorly understood. Genus- to species-level taxa are currently distinguished by plastic morphological characters. We revised the superfamily from species- to family-levels using a combined morphological and molecular approach. A phylogeny using two nuclear and three mitochondrial markers recovered Colobometridae and Himerometridae as paraphyletic and Mariametridae and Zygometridae as polyphyletic. Within genus Himerometra (Himerometridae), sequence data and detailed morphological examinations of multiple specimens of H. magnipinna, …

Leucothoe Eltoni Sp. N., A New Species Of Commensal Leucothoid Amphipod From Coral Reefs In Raja Ampat, Indonesia (Crustacea, Amphipoda), James Darwin Thomas

Marine & Environmental Sciences Faculty Articles

A new species of leucothoid amphipod, Leucothoe eltoni sp. n., is described from coral reefs in Raja Ampat, Indonesia where it inhabits the branchial chambers of solitary tunicates. With an inflated first gnathopod superficially resembling the genus Paraleucothoe, this new species has a two-articulate maxilla 1 palp characteristic of the genus Leucothoe. While described from coral reef environments in tropical Indonesia and the Philippines, it is an established invasive species in the Hawaiian Islands. The most likely mode of introduction was a US Navy dry dock transported to Pearl Harbor in 1992 from Subic Bay, Philippines.

The Alternate Assessment Based On Alternate Achievement Standards Eligibility Decision-Making Process, Karren Streagle, Karen Wilson Scott

The Qualitative Report

Under No Child Left Behind (NCLB), students with significant intellectual disabilities (ID) are allowed to take alternate assessments based on alternate achievement standards (AA-AAS) in lieu of the standardized assessments taken by their peers, however evidence suggests that IEP teams inconsistently and sometimes inaccurately apply established participation criteria in finding students eligible to participate in AA-AAS. The purpose of this generic qualitative study was to describe the decision-making process used by Individual Education Program (IEP) teams to identify students eligible to participate in AA-AAS. Thirteen case managers of students taking the Virginia Alternate Assessment Program (VAAP) from central Virginia participated …

Teachers’ Perceptions And Conceptualizations Of Low Educational Achievers: A Self-Fulfilling Prophecy Of Disengagement For Future Neets, Gabriella Agrusti, Francesca Corradi

The Qualitative Report

The NEETs phenomenon in Italy is not a recent one, but it increased dramatically after the Global Financial Crisis. As in France many different factors influence it, but the prevailing two are the skills mismatch and the youth generations’ discouragement. Whereas in France the role of the school is crucial into tackling NEETs, in Italy the initiatives are mainly carried out by local authorities and small and medium enterprises. Therefore, more research is needed that sheds lights on teachers’ role in dealing with low educational achievers. This exploratory study investigates teachers’ perceptions and conceptualizations of low educational achievers in upper …

Does The Stellar Disc Flattening Depend On The Galaxy Type, A. V. Mosenkov, N. Ya. Sotnikova, V. P. Reshetnikov, D. V. Bizyaev, Stefan Kautsch

Chemistry and Physics Faculty Articles

We analyse the dependence of the stellar disc flatness on the galaxy morphological type using 2D decomposition of galaxies from the reliable subsample of the Edge-on Galaxies in SDSS catalogue. Combining these data with the retrieved models of the edge-on galaxies from the Two Micron All Sky Survey and the Spitzer Survey of Stellar Structure in Galaxies catalogue, we make the following conclusions.

1. The disc relative thickness z₀/h in the near- and mid-infrared passbands correlates weakly with morphological type and does not correlate with the bulge-to-total luminosity ratio B/T in all studied bands.

2. Applying a 1D photometric …

Identity Construction In The Margins:A Case Study Involving Non-Conforming Youth, Alice M. Harnischfeger

The Qualitative Report

This qualitative instrumental case study explores how student members of an alternative educational program in a successful public middle school constructed identity, and how they interpreted their schooling experiences in relation to hegemonic educational practices. It draws on sociocultural and postmodern theories to focus on these youths’ identities and on their perspectives of self and school practices. Its multiple methods collected data through alternative and mainstream classroom observations, focus group sessions, semi-structured individual interviews with students, parents, and school professionals, and an analysis of school documents. The youth participants of this study held multiply-constructed identities, and actively resisted and affirmed …

A Comparative Evaluation Of Mitigation Wetlands In Broward County, Florida, Using Chironomid (Ditera) Pupal Exuviae: A Potential Technique For Assessing Mitigation Success, Ryan St. George

HCNSO Student Theses and Dissertations

Wetland resources in South Florida are regulated at three redundant jurisdictional levels: local or municipal regulations set forth by many independent jurisdictions, State regulations derived directly from Florida Statutes, and Federal regulations promulgated primarily under the Clean Water Act. All three levels of government can have jurisdiction over projects that affect regulated wetland resources, yet inconsistent policies and standards remain and continue to confound regulators despite decades of intensive coordination efforts and a rapidly growing scientific research base. The size of a wetland mitigation area is of primary consideration when evaluating its perceived ecological value, although wetland mitigation areas constructed …

Climate Change Resilience And Socioeconomic Impacts Of Mpas And Mpa Networks In The Caribbean - Case Study: Evaluation Of The Effectiveness Of The Management Of Mpas And Coastal Zones In The Dominican Republic, Andrea Isabella Vogel

HCNSO Student Capstones

Many Caribbean nations have established MPAs to preserve marine biodiversity and maintain their economically important marine resources. In some Caribbean nations, in particular the Dominican Republic, most MPAs have failed in these respects and have remained “paper parks” due to being modeled along traditional conservation lines without careful consideration of socioeconomic factors, good management practices or increasingly important climate change factors. Successful Caribbean MPAs and MPA networks effectively function as refuges, attractions, sources of socioeconomic development and ecosystem-based climate change resilience mechanisms. The latter is of utmost importance to Small Island Developing States (SIDS) and other larger island developing states …

Benthic Invertebrate Communities And Habitat Characterization Of The Pourtalès Terrace, Florida With Analysis Of The Deepwater Coral Habitat Areas Of Particular Concern And The East Hump Marine Protected Area, Jana K. Ash

HCNSO Student Theses and Dissertations

The Pourtalès Terrace is a gently curved, narrow triangular platform that parallels the Florida Keys for 213 km running from southern Key Largo to between Key West and the Marquesas Keys. The main Terrace surface begins in 200 m and dips gently to approximately 450 m, where the Pourtalès Escarpment slopes steeply to the deep floor of the southern Straits of Florida. The Terrace platform exhibits a wide variety of Neogene-age geological features, including high-relief ledges, mounds, sinkholes and deep-water biogenic build-ups called bioherms. Previous research revealed dense and diverse benthic assemblages dominated by stylasterid hydrocorals, octocorals and sponges.

This study examined the effects of the January 2010 cold spell on mangrove utilizing coral reef fishes off the southeast coast of Florida, USA, in the vicinity of Biscayne National Park (BNP). An ongoing, fishery-independent mangrove visual survey documenting fish assemblages in BNP provided data from the years 1998 to 2014 for examination. Of particular interest were the presence, abundance, and size structure for five mangrove utilizing coral reef fishes: sergeant major (Abudefduf saxatilis), yellowfin mojarra (Gerres cinereus), schoolmaster snapper (Lutjanus apodus), gray snapper (Lutjanus griseus), and great barracuda (Sphyraena barracuda …

Assessment Of Nursery-Raised Acropora Cervicornis Transplants In The Upper Florida Keys, Matthew Ware

HCNSO Student Theses and Dissertations

Over the last 40 years, the Caribbean has lost half of its live coral cover, mostly in the form of Acropora cervicornis and A. palmata, due to disease, bleaching from rising water temperatures, and other stressors. To help restore these corals to reefs in Florida, the Coral Restoration Foundation (CRF) created nearshore nurseries and transplanted over 30,000 acroporid colonies across the Florida Keys. The objective of this thesis was to evaluate the growth, survivorship, and condition of nursery-raised A. cervicornis colonies that were part of two transplant projects: 1) photographic analyses of 17 past CRF transplant projects over the …

Connectivity Of Reef Fishes Between Mangroves And Coral Reefs In Broward County, Florida, Jennifer Savaro

HCNSO Student Theses and Dissertations

Many marine fishes use the mangrove ecosystem for foraging, protection, spawning, and as a nursery habitat. To develop a better understanding of energy flow between the coastal mangrove and coral reef ecosystems, the ontogentic migration and trophic connectivity of reef fishes were examined through the use of carbon (C), nitrogen (N), and oxygen (O) stable isotope ratios. Juvenile and adult gray snapper Lutjanus griseus, lane snapper L. synagris, bluestriped grunt Haemulon sciurus, French grunt H. flavolineatum, sailor’s choice H. parra, yellowfin mojarra Gerres cinereus, and great barracuda Sphyraena barracuda were collected from both mangrove …

Staghorn Coral, Acropora Cervicornis, Restoration In South Florida: Growth And Survivorship Of Outplanted Nursery Corals, Meaghan Johnson

HCNSO Student Theses and Dissertations

This thesis provides a detailed analysis of the growth and survivorship of outplanted Acropora cervicornis corals from underwater nurseries within three regions of the Florida Reef Tract. Substantial loss of stony coral cover on Florida’s coral reefs, including the branching staghorn coral, Acropora cervicornis, has occurred for decades due to disturbances such as disease, temperature induced bleaching, hurricanes, sedimentation, and pollution. This rapid population decline contributed to A. cervicornis being listed as a threatened species under the U.S. Endangered Species Act in May 2006. To aid in the recovery of the species, coral fragments were grown in underwater nurseries …

Cross-Shelf And Latitudinal Benthic Community Investigation In The Nearshore Habitats Of The Northern Florida Reef Tract, Katelyn Klug

HCNSO Student Theses and Dissertations

The Florida Reef Tract (FRT) extends from the tropical Caribbean northward along the Florida coast into a warm temperate environment where tropical reef communities diminish with increasing latitude. This study was designed to map the nearshore benthic habitats including coral reefs and evaluate how the benthic communities differ between habitats and along the coast.

Benthic communities across the northern FRT from Key Biscayne to Hillsboro Inlet (25.5°-26.3° N) were digitized from aerial photography taken in 2013 at a 1:1,000 scale. Three main hard-bottom habitat types were identified that ran parallel to shore and consecutively further away from shore: Colonized Pavement, …
