Deep Learning Of High-Resolution Aerial Imagery For Coastal Marsh Change Detection: A Comparative Study, Grayson R. Morgan, Cuizhen Wang, Zhenlong Li, Steven R. Schill, Daniel R. Morgan

Faculty Publications

Deep learning techniques are increasingly being recognized as effective image classifiers. Aside from their successful performance in past studies, the accuracies have varied in complex environments, in comparison with the popularly of applied machine learning classifiers. This study seeks to explore the feasibility of using a U-Net deep learning architecture to classify bi-temporal, high-resolution, county-scale aerial images to determine the spatial extent and changes of land cover classes that directly or indirectly impact tidal marsh. The image set used in the analysis is a collection of a 1-m resolution collection of National Agriculture Imagery Program (NAIP) tiles from 2009 and …

Offshore Spreading Of A Supercritical Plume Under Upwelling Wind Forcing: A Case Study Of The Winyah Bay Outflow, Alexander E. Yankovsky, Douglas Cahl, George Voulgaris

Faculty Publications

In this study, we present observations of the Winyah Bay (WB) plume (SC, United States) formed by high freshwater discharge and a moderate upwelling-favorable wind acting continuously for ∼1.5 days prior to the shipboard survey. If a similar wind forcing persists over a longer period, the plume turns upstream (against its natural propagation) and curves offshore forming a “filament” with minimal transverse spreading, as seen in numerous satellite images. The observed plume comprises a train of tidal sub-plumes undergoing rotational adjustment and being transported offshore by Ekman dynamics. The WB outflow is supercritical in terms of the interior Froude number. …

The Mediating Effect Of Depression On The Relation Between Interpersonal Needs And Suicidal Ideation Among Chinese Transgender Women, Ruijie Chang, Chengbo Zeng, Shan Qiao Ph.D., Huwen Wang, Chen Xu, Xiaoyue Yu, Tiecheng Ma, Ying Wang, Xiaoming Li Ph.D., Yong Cai

Faculty Publications

Background: Transgender women are at high risk of depression and suicidal ideation. The interpersonal theory of suicide proposes that suicidal ideation could be a consequence of high interpersonal needs (thwarted belongingness and perceived burdensomeness). The current study tests this theory and investigates whether depression could mediate the relationship between interpersonal needs and suicidal ideation among transgender women in Shenyang, China.

Methods: A total of 198 transgender women were recruited by snowball sampling. A cross-sectional study was conducted through a structured questionnaire. Suicidal ideation, depression, and interpersonal needs were assessed. Path analysis was used to carry out the research goals and …

Effect Of Defects Part I: Degradation Of Constitutive Coefficients As An Input To The Composite Failure Model With Microvoids And Porosity, Vahid Tavaf, Sourav Banerjee

Faculty Publications

It is always challenging to provide appropriate material properties for a composite progressive failure model. The nonstandard percentage reduction method that is commonly used to degrade the material constants with micro-scale defects generates tremendous uncertainty in failure prediction. The constitutive matrix is composed of multiple material constants. It is not necessary that all constants degrade either equally or linearly due to a certain state of material defects. With this very concern in mind, this article presents a guideline for using a quantified perturbation for each coefficient appropriately. It also presents distribution of effective material properties (EMPs) in unidirectional composite materials …

Unmanned Aerial Remote Sensing Of Coastal Vegetation: A Review, Grayson R. Morgan, Michael E. Hodgson, Cuizhen Wang, Steven R. Schill

Faculty Publications

Coastal wetlands contribute greatly to our coasts economically and ecologically. The utility of coastal wetland vegetation, along with the multitude of dynamic forces they encounter, suggests the need of regular monitoring for sustainable management. While traditional in situ survey methods and remote sensing from space and manned platforms have provided means to monitor and study the coastal zone thus far, the recent developments of small unmanned aerial systems (sUAS) fill a small void between traditional in situ survey methods and the high spatial resolution of manned aircraft imagery. As an on-demand personal remote sensing device, an sUAS can be deployed …

Faculty Publications

Background

The Glanville fritillary (Melitaea cinxia) butterfly is a model system for metapopulation dynamics research in fragmented landscapes. Here, we provide a chromosome-level assembly of the butterfly's genome produced from Pacific Biosciences sequencing of a pool of males, combined with a linkage map from population crosses.

Results

The final assembly size of 484 Mb is an increase of 94 Mb on the previously published genome. Estimation of the completeness of the genome with BUSCO indicates that the genome contains 92–94% of the BUSCO genes in complete and single copies. We predicted 14,810 genes using the MAKER pipeline and …

Self-Relabeling For Noise-Tolerant Retina Vessel Segmentation Through Label Reliability Estimation, Jiacheng Li, Ruirui Li, Ruize Han, Song Wang

Faculty Publications

Background Retinal vessel segmentation benefits significantly from deep learning. Its performance relies on sufficient training images with accurate ground-truth segmentation, which are usually manually annotated in the form of binary pixel-wise label maps. Manually annotated ground-truth label maps, more or less, contain errors for part of the pixels. Due to the thin structure of retina vessels, such errors are more frequent and serious in manual annotations, which negatively affect deep learning performance.

Methods In this paper, we develop a new method to automatically and iteratively identify and correct such noisy segmentation labels in the process of network training. We consider …

Disruptions Of The Human Connectome Associated With Hemispatial Neglect, Sadhvi Saxena, Zafer Keser, Chris Rorden, Leonardo Bonilha, Julius Fridriksson Ph.D., Alexandra Walker, Argye Elizabeth Hillis

Faculty Publications

Background and Objectives

Hemispatial neglect is a heterogeneous and complex disorder that can be classified by frame of reference for “left” vs “right,” including viewer-centered neglect (VCN, affecting the contralesional side of the view), stimulus-centered neglect (SCN, affecting the contralesional side of the stimulus, irrespective of its location with respect to the viewer), or both. We investigated the effect of acute stroke lesions on the connectivity of neural networks that underlie VCN or SCN.

Methods

A total of 174 patients within 48 hours of acute right hemispheric infarct underwent a detailed hemispatial neglect assessment that included oral reading, scene copy, …

Chronic Background Radiation Correlates With Sperm Swimming Endurance In Bank Voles From Chernobyl, Kati Kivisaari, Sara Calhim, Zbyszek Boratyríski, Timothy Mousseau, Anders P. Møller, Tapio Mappes

Faculty Publications

Sperm quantity and quality are key features explaining intra- and interspecific variation in male reproductive success. Spermatogenesis is sensitive to ionizing radiation and laboratory studies investigating acute effects of ionizing radiation have indeed found negative effects of radiation on sperm quantity and quality. In nature, levels of natural background radiation vary dramatically, and chronic effects of low-level background radiation exposure on spermatogenesis are poorly understood. The Chernobyl region offers a unique research opportunity for investigating effects of chronic low-level ionizing radiation on reproductive properties of wild organisms. We captured male bank voles (Myodes glareolus) from 24 locations in the Chernobyl …

Discursive Incarceration: Black Fragility In A Divided Public Sphere, Meili Steele

Faculty Publications

The expression of fragility has always been a difficult and complex matter for African Americans, for the discourse of mainstream media is set up to both sustain and misrecognize their fragility . Even though the black public sphere split off from the dominant public sphere after the Civil War to enable distinctive forms of expression, the “practiced habits” of which Coates speaks continued working within the structures of the dominant discourse. My essay will analyze the structure of America’s indifference to fragility in six parts. In the first section, I will introduce a normative problematic that can track how the …

Freedom, Democracy, And The Right To Education, Derek W. Black

Faculty Publications

While litigation continues in an effort to establish a fundamental right to education under the U.S. Constitution, the full historical justification for this right remains missing—a fatal flaw for many jurists. This Article fills that gap, demonstrating that the central, yet entirely overlooked, justification for a federal right to education resides in America’s education story during the era of slavery and Reconstruction.

At that time, education was first and foremost about freedom. The South had criminalized education to maintain a racialized hierarchy that preserved slavery. Many African Americans, seeing education as the means to both mental and physical freedom, made …

Disablist Propaganda: Evil On One Hand, And A Hook For The Other, Lauren Reitz, Richard Murphy

University of South Carolina Upstate Student Research Journal

Despite its publication by J.M. Barrie in 1904, Peter and Wendy has attracted very little critical attention. Perhaps the story is so beloved for its adventure-packed plot, and sweet message about a boy who never grows old, that even scholars have trouble criticizing it—despite its obvious calls for analysis as film and literary adaptations continue to appear.

However, most concerning is an apparent gap in the analysis of the story’s disabled villain, Captain Hook, through a modern Disability Studies lens. The following textual analysis of Captain Hook will serve to call attention to the way his disability plays into his …

The Challenge-Hindrance Model Of Stress And Its Intersections With The Conservation Of Resources Theory, Divya A. Srijay, Justin Travis Dr.

University of South Carolina Upstate Student Research Journal

This paper briefly summarizes the challenge-hindrance model of stress (CHM) through its basis in the transactional theory of stress, and it integrates modern theories of stress found in social psychology and management literature. In doing so, we provide a content map/process model to guide future research that can contribute to the creation of a more effective measure of the secondary appraisals of stressors.

Although psychometric and related statistical concerns regarding extant measures have been noted and discussed in the literature, our hope is that the proposed model may aid in the conceptualization of the nomological network of the stress process …

Emergent Bilingual Students And Middle Level Social Studies: Overcoming The “Huh?”, Asten Leonard

South Carolina Association for Middle Level Education Journal

Throughout my career in middle level education, I have taken note of how my emergent bilingual students react to assignments and lessons in my history classes. Direct instruction and primary source materials can prove especially challenging. In this article, I hope to provide middle school Social Studies educators with strategies that I have found to be successful in my classroom when teaching English Learner (EL) students history. Building a relationship, adhering to accommodations, scaffolding concepts and vocabulary, and incorporating a student’s culture into lessons can help us overcome the “Huh?” in the classroom.

No Cap: Unlocking The Self-Concepts Of Students To Promote Limitless Identities, Walter Lee

South Carolina Association for Middle Level Education Journal

If students do not perceive themselves as capable, they will likely decline opportunities that threaten their self-beliefs. This requires educators to create redefining moments for students to experience struggle in a safe environment that ultimately encourages students to remove personal limitations. When teachers are critical about ways to respond to negative, limiting self-concepts, students may conquer breakthroughs in learning. In this article, I suggest that a change in self-concept represents a change in mindset, producing significant learning outcomes. To accomplish this, I will discuss self- concept, self-efficacy, and implications on teaching, using the CARE theory of self-concept development.

Melody And Memory: Black Language In The Low Country, Dywanna Smith, Kenesha Johnson

South Carolina Association for Middle Level Education Journal

Black Language has historically been marginalized as a broken form of Standard English forcing the speakers of this language to conform and devalue their native tongue. This impact has led to a negative stigma on Black Language and forced Black people to relinquish their cultural literacies. This study reflects on understanding why Black Language must be recognized as a legitimate language. It also illustrates why Black Language should be welcomed into the classroom as it provides a pathway to self-actualization affording Black students the opportunity to self-define and self-validate their existence. Special emphasis is placed on how language impacts adolescent …

Connecting Weirdness And Wonder To Mathematics, Elizabeth Basile, Deborah H. Mcmurtrie, Bridget K. Coleman

South Carolina Association for Middle Level Education Journal

Middle school students are weird and wonderful. Why not bring some of that weirdness and wonder into the mathematics classroom? Effective teachers of mathematics can create a culture of engagement, curiosity, and collaboration in mathematics instruction by presenting “weird” problems (as opposed to word problems) and giving students opportunities to explore their wonderings. Inspired by “the bizarreness effect,” the problems presented here are infused with humor and designed to intrigue young adolescents.
