Finding A Place To Belong: The Role Of Social Inclusion In The Lives Of Homeless Men, Meaghan Bell, Christine A. Walsh

The Qualitative Report

This study explores the role of informal social support networks of male homeless shelter residents. Authors utilized ethnographic methods, relationality and reflexive research approaches and key informant interviews with 10 shelter residents to investigate perceptions of belonging in overcoming social exclusion and countering the stigmatization cast onto as a result of their condition of homelessness. Study findings challenge our normative conceptions of homelessness by discerning between “rooflessness” and “rootlessness” suggesting that homelessness is more than the absence of shelter, but rather denotes the absence of support and inclusion in one’s community. This research highlights a community within the shelter characterized …

Exploring The Professional Beliefs Of An Efl Teacher: A Narrative Inquiry, Seyyed Ali Ostovar-Namaghi, Shabnam Norouzi, Mobina Hosseini

The Qualitative Report

The applied science model of teacher education implies that the relationship between theory and practice is unidirectional. In this study, however, the researchers make a case in the opposite direction, i.e., they believe that professional practice can also shed some light on theories of language teaching. Since narrative inquiry is best for capturing the detailed stories or life experiences of a single life, the researchers took it as a legitimate mode of research to uncover and make sense of the professional experience of an experienced and professionally popular language teacher. Analysis revealed six themes, which reflect the participant’s professional beliefs. …

Natural Vs. Anthropogenic Sedimentation: Does Reducing A Local Stressor Increase Coral Resilience To Climate Change?, Francesca Fourney

HCNSO Student Theses and Dissertations

Corals face serious worldwide population declines due to global climate change in combination with direct anthropogenic impacts. Global climate change is difficult to manage locally, but policy makers can regulate the magnitude of local stressors affecting reefs. The objective of this experiment is to investigate if reducing sedimentation will enable reef corals to better endure global climate change. It has been shown that some coral species can handle climate change stress when provided with additional energy resources. Here I tested if the capacity of corals to cope with climate change can be improved when their ability to feed and photosynthesize …

The Our Florida Reefs Coastal Use Survey: An Online Survey To Support Stakeholder Management Recommendations For Southeast Florida, Amanda Rose Costaregni

HCNSO Student Theses and Dissertations

Coral reefs are an important resource world-wide. Unfortunately, coral reef conditions are declining in many areas due to both global and local stressors. The objective of this study was to survey stakeholders in southeast Florida to better understand reef use in the region. Stakeholders spatially identified where and how often they conducted their activities. These data were compiled and analyzed in GIS to determine spatial use patterns. Both location and intensity of use were analyzed to determine which areas may be under greater stress from recreational activities. It was found that reef use was not evenly distributed in the region …

Background

Patterns of genetic and genomic variance are informative in inferring population history for human, model species and endangered populations.

Results

Here the genome sequence of wild-born African cheetahs reveals extreme genomic depletion in SNV incidence, SNV density, SNVs of coding genes, MHC class I and II genes, and mitochondrial DNA SNVs. Cheetah genomes are on average 95 % homozygous compared to the genomes of the outbred domestic cat (24.08 % homozygous), Virunga Mountain Gorilla (78.12 %), inbred Abyssinian cat (62.63 %), Tasmanian devil, domestic dog and other mammalian species. Demographic estimators impute two ancestral population bottlenecks: one >100,000 years …

A Comparison Of Infaunal Community Structure Between Pre- And Post Construction Sampling Of Artificial Fdot Rock- Pile Reefs In Broward County, Florida, Joan Lorraine Guerra

HCNSO Student Theses and Dissertations

Artificial reefs (ARs) are generally created with the intention of increasing local fish populations, biodiversity and corresponding habitat productivity, most often in support of commercial and recreational uses (e.g., diving and fishing). Numerous studies have investigated the communities that develop on artificial reefs. By contrast, far less research has focused on the surrounding infaunal communities, which represent critical trophic resources for many species that populate both natural and artificial reefs, and which may be affected both by AR deployment and the organisms that subsequently recruit to them. This study compared infaunal organism abundances at four sites between the inner and …

HCNSO Student Theses and Dissertations

The assemblage structure, abundance, biomass, and vertical distribution of juvenile reef fishes in the offshore pelagic habitat of the northern Gulf of Mexico are described as part of the NOAA-supported Offshore Nekton Sampling and Analysis Program. The results presented here are from a 3-month, continuous sampling series in 2011 in which discrete depth strata from 0 to 1500 m were sampled using a 10-m² MOCNESS midwater trawl. This is the first study to examine pelagic juvenile reef fish distributions across the entire oceanic northern Gulf of Mexico seaward of the continental shelf break after the Deepwater Horizon Oil Spill. …

Faunal Composition And Distribution Of Pelagic Larval And Juvenile Flatfishes (Teleostei: Pleuronectiformes) In The Northern Gulf Of Mexico: Connectivity Between Coastal And Oceanic Epipelagic Ecosystems, Lacey Malarky

HCNSO Student Theses and Dissertations

Pleuronectiformes (flatfishes) occur throughout the global oceans, and have high ecological and commercial importance in some areas. Though much is known regarding life history, abundance, and distribution for the benthic adult stage of flatfish species, much less is known about the pelagic larval phases of flatfishes in the open ocean. Taxonomic uncertainty and limited sampling in the oceanic Gulf of Mexico contribute to data gaps with respect to the distribution of early life history stage of flatfishes in this region. Knowledge of the faunal composition, abundance and distribution of larval flatfishes, such as members of Bothus, which have extended …

Feeding Ecology Of The Invasive Lionfish (Pterois Spp.) And Comparison With Two Native Species: Schoolmaster Lutjanus Apodus (Walbaum, 1792) And Graysby Cephalopholis Cruentata (Lacepède, 1802), Jesse J. Secord

HCNSO Student Theses and Dissertations

Predator satiation and prey-size preference were determined for locally caught lionfish, schoolmaster, and graysby, all co-occurring predatory fishes in the Florida coral reef ecosystem. Individuals were evaluated by exposing them to wild-caught killifish over a gradient of four size classes (20 mm to 60 mm, in 10 mm increments). Preference trials extended over a 2 hr time period and were filmed to determine the order in which each prey item was consumed. Satiation was evaluated by exposing the predators to an equal number of excess prey items for 24 hrs and evaluating consumed prey weight. Lionfish and schoolmaster showed a …

The Effects Of Petroleum Pollutants On Sea Urchins Reproduction And Development, Kellie C. Pelikan

HCNSO Student Theses and Dissertations

Disturbances, such as mass pollution events, threaten the health of vulnerable ecosystems. Recent media attention has focused on the devastating mass oil spills, but daily petroleum input from recreational and commercial ship bilge release has been overlooked. The focus of this study was the effect of petroleum products found in bilge water on fertilization success and larval viability of two sea urchin species, Lytechinus variegatus and Eucidaris tribuloides. Unlike other pollutant studies that have focused on sperm characteristics and concentrations, I chose to examine how egg integrity was compromised by petroleum products. Scanning electron microscopy revealed eggs were degraded when …

Holding Death At Bay Vs. Prolonging Life: Indexing Fatalism And Optimism In The Ideology Of Health, Genetics, And Family History In The U. S. And South Korean Media, Soo Jung Hong, Susan Strauss

The Qualitative Report

Media discourse creates and shapes views of personhood, of possibilities, of wellness, and at the same time, these views and beliefs, in their turn, shape media discourse. Broadcasts of health-related edutainment programs and advertisements are rich sources for the discovery of stances concerning health and illness. We examine media discourse in the United States and South Korea, and uncover consistent indexical patterns pointing to overall ideologies of fatalism in the U.S. and optimism in South Korea. Specifically, from an indexicality-based perspective, we identify the patterned ways in which the ideologies of fatalism and optimism are indexed with regard to agency …

Applying A Socio-Ecological Framework To Thematic Analysis Using A Statewide Assessment Of Disproportionate Minority Contact In The United States, Dawn X. Henderson, Tiffany Baffour

The Qualitative Report

Disproportionate minority contact (DMC) in the United States represents a critical social challenge to promoting the ideals and values of social justice. The ecological nature of DMC, a phenomenon emerging from the intersection of micro- and macro-level factors, necessitates the application of systems theories in understanding the issue and designing solutions to address it. This article illustrates the application of socio-ecological systems theory in thematic analysis, drawing associations across multiple systems between contributing factors to DMC in the juvenile justice system in North Carolina, USA. Analysis examined data from 6 focus groups comprised of 55 statewide stakeholders involved in the …

Curvature: A Geometric Villain That Ruins Our Instinctive Perception Of Nature, Vehbi Emrah Paksoy

Mathematics Colloquium Series

Our perception of nature is based on evolutionary wiring of our brain and observations we make via our senses. But, in reality, many scientific and technological advancements are based on non-intuitive rules and principles that can only be explained by the ultimate abstraction that is embedded in mathematics. In this talk, I will discuss the concept of curvature and argue how it explains the “unexplainable”. We will see how the curvature proves that the earth is rotating, how good the soap bubbles are at proving profound mathematical results, and if the two dimensional residents can determine the shape of their …

Evaluation Of Frictional Forces Between Brackets Of Different Types At Various Angulations And An Arch Wire: With And Without Pulsating Vibration, Benjamin M. Christman

Student Theses, Dissertations and Capstones

Objective: The objective of this study was to determine the effect of pulsating vibration on the sliding resistance between orthodontic brackets and stainless steel wires. Brackets were placed at two different angulations (0° and 5°) to simulate leveling of a tipped tooth during tooth movement. Pulsating vibration was delivered via the AcceleDent device.

Background: Friction is defined as a force that retards or resists the relative motion of two objects in contact, and its direction is tangential to the common boundary of the two surfaces in contact. This has been of interest to the orthodontist since the mid-20th century. Since …

Understanding Transitional Justice And Its Two Major Dilemmas, Jared Bell

Journal of Interdisciplinary Conflict Science

Transitional justice is an ever growing field and greatly intersects with conflict science and peace studies. With the horrific crimes committed during World War II and the latter half of the 20^th century societies now more than ever before are devising processes, mechanisms, and policies to move past gross human rights violations or communal violence. However, these mechanisms much like anything else are not perfect and come with a variety of dilemmas. In particular two main dilemmas plague transitional justice which this paper aims to deal with: Getting to Truth and Reality versus Expectation. Within the context of …

Humeral Retrotorsion In Developing Children And Its Relationship To Throwing Sports, Elliot M. Greenberg

Department of Physical Therapy Student Theses, Dissertations and Capstones

Background: Baseball players exhibit a more posteriorly oriented humeral head or humeral retrotorsion (HRT) in the dominant arm, likely representing an adaptive response to the stress of throwing. This adaptation is thought to occur while skeletally immature, however there is limited research detailing how throwing while young influences the development HRT. In addition, it is currently unclear how this changing osseous orientation influences shoulder motion within young athletes. Purpose: To determine the influence of throwing and age on the development of asymmetry in HRT and shoulder range of motion (ROM); and analyze the relationship between HRT and ROM. Study Design: …

Assessing Orthodontic-Bracket Impacts On Lip Profile At Bonding And Debonding Stages, Martin Trockel

Student Theses, Dissertations and Capstones

Introduction: One factor that contributes greatly to the lower face appearance and orthodontists have the ability to affect is lip profile. Clinical assessment of the lip profile is an important element in the decision of orthodontic treatment planning and in the evaluation of treatment progress and outcome. Three known factors influence the lip profile; the lip thickness, the underlying bone, and the tooth position. The positions and inclinations of the anterior teeth can affect the lip position, but it is unclear whether orthodontic brackets bonded to the labial surface of anterior teeth move the lip position and thereafter change the …

Effects Of Sodium Hypochlorite On Enamel Composition, Sonni Pellillo

Student Theses, Dissertations and Capstones

The purpose of this study was to evaluate the effects of sodium hypochlorite on the organic and inorganic composition of enamel. Background: With the advent of enamel bonding for orthodontic appliances in the late 1970s, it has been shown that traditional phosphoric acid etching affects the inorganic portion of the enamel.1, 2 In an attempt to enhance the acid etching pattern and, furthermore, the bond strength, additional pretreatment techniques that target the organic components of the enamel biofilm have been proposed. One such method is the non-invasive enamel pretreatment with 5.25% sodium hypochlorite (NaOCl) prior to phosphoric acid etching.3, 4 …

Semi-Automated Object-Based Classification Of Coral Reef Habitat Using Discrete Choice Models, Steven Saul, Samuel J. Purkis

Marine & Environmental Sciences Faculty Articles

As for terrestrial remote sensing, pixel-based classifiers have traditionally been used to map coral reef habitats. For pixel-based classifiers, habitat assignment is based on the spectral or textural properties of each individual pixel in the scene. More recently, however, object-based classifications, those based on information from a set of contiguous pixels with similar properties, have found favor with the reef mapping community and are starting to be extensively deployed. Object-based classifiers have an advantage over pixel-based in that they are less compromised by the inevitable inhomogeneity in per-pixel spectral response caused, primarily, by variations in water depth. One aspect of …
