Speech Is My Hammer, It's Time To Build: Hip Hop, Cultural Semiosis And The Africana Intellectual Heritage, Samuel T. Livingston

Journal of Hip Hop Studies

The article examines Hip Hop music's relationship with African cultural symbolism and the discipline of Africana Studies. The author maintains that Africana Studies must reclaim the study of cultural semiosis, which may be used to contextualize Hip Hop praxis. Examining semeiotic traces within African and Afrodiasporic primary sources, including Hip Hop lyrics, the article posits that Hip Hop is the latest development in a long tradition of Afro-Kemetic oral artistry, semeiotic systems and the uses of these dual literacies as modes of resistance and affirmations of Black historical and cultural agency. The article adapts Harryette Mullen's literary model of African …

Baadassss Gangstas: The Parallel Influences, Characteristics And Criticisms Of The Blaxploitation Cinema And Gangsta Rap Movements, Dustin Engels

Journal of Hip Hop Studies

Serving as two of the most visible African American cultural movements, blaxploitation cinema and gangsta rap played essential roles in giving African American artists an outlet to establish a new black identity for mainstream audiences. After exploring the similarities between the cultural and economic conditions that spawned both movements, this essay examines the parallel techniques by which the preeminent entries in both genres established themselves as culturally relevant for African American audiences. These techniques included a reliance on place and space to establish authenticity, as well as employing African American myths and folklore such as the Signifying Monkey and the …

Listen To The Story: Banksy, Tyler The Creator, And The Growing Nihilistic Mindset, Duri Long

Journal of Hip Hop Studies

Art, as an expression of feelings, worldviews, and personal beliefs, is a reflection of our environment and how we interact with it. In this way, urban art such as rap music and graffiti can serve as a lens through which we are able to examine the state of the urban environment. Building on community literature that addresses the presence of nihilism in rap music, this work will establish that nihilism is a prevalent theme in the work of two artists: Tyler the Creator's rap music and BANKSY's graffiti art. By examining the growing subculture and appeal of urban art in …

Not Just Anna Nicole Smith: Cleavage In Bankruptcy, David G. Epstein, Casey Ariail, David M. Smith

Emory Bankruptcy Developments Journal

This is an essay about the unwarranted erosion of two basic bankruptcy principles: the cleavage effect of a debtor's filing of a bankruptcy petition and the equality of treatment of prepetition unsecured claims. These are two of the most fundamental bankruptcy concepts. First courts and then Congress have fashioned rules favoring the prepetition unsecured claims of vendors and lessors that are inconsistent with these concepts. The authors explore the origins of such favored treatment, question the commonly offered policy justifications, and argue that the prepetition unsecured claims of vendors and lessors generally should be afforded the same treatment in bankruptcy …

Retaining The Hope That Rejection Promises: Why Sunbeam Is A Light That Should Not Be Followed, Benjamin H. Roth

Emory Bankruptcy Developments Journal

Sunbeam Products, Inc. v. Chicago American Manufacturing, LLC incorrectly altered the remedies available to a trademark licensee after a debtor licensor has rejected the license. Decided in July 2012, this decision by the U.S. Court of Appeals for the Seventh Circuit conflicts with decisions going back more than twenty-five years, when the U.S. Court of Appeals for the Fourth Circuit decided Lubrizol Enterprises, Inc. v. Richmond Metal Finishers, Inc. During that span of time, licensees had a single remedy upon rejection of the license: damages in the way of an unsecured prepetition claim. Licensees were not granted specific performance, and …

Co-Evolution Of Mitochondrial And Nuclear Genomes In Caenorhabditis , Emily Elaine Hill

Browse all Theses and Dissertations

Nuclear and mitochondrial genomes have co-adapted through evolution. Interactions between these genomes are required for mitochondrial functions. My goal was to determine how divergence of these interactions affected mitochondrial function and organismal fitness. The impact of divergence between Caenorhabditis briggsae populations and between C. briggsae and its sister species, C. nigoni was assessed. To accomplish this, four sets of hybrid lines were constructed. Each hybrid line possessed the nuclear genome of one parental strain and mitochondria from another parental strain. Two sets of hybrid lines were constructed from strains derived from different C. briggsae populations. The other two were constructed …

Breaking Up Payday: Anti-Agglomeration Zoning & Consumer Welfare, Sheila R. Foster

Faculty Scholarship

In the last decade, dozens of local governments have enacted zoning ordinances designed to limit the concentration of payday lenders and other alternative financial services providers (AFSPs), such as check-cashing businesses and auto title loan shops, in their communities. The main impetus for these ordinances is to shield economically vulnerable residents from the industry’s lending practices in the absence of sufficiently aggressive federal and state consumer protection regulation. This Essay casts considerable doubt on whether zoning is the appropriate regulatory tool to achieve the consumer protection and welfare goals animating these ordinances. The author’s analysis of the aftermath of payday …

Concurrent Identity Training Is Not Necessary For Associative Symmetry In Successive Matching, Heloísa Cursi Campos, Peter J. Urcuioli, Melissa Swisher

Department of Psychological Sciences Faculty Publications

Pigeons demonstrate associative symmetry after successive matching training on one arbitrary and two identity relations (e.g., Urcuioli, 2008). Here, we tested whether identity matching training is necessary for this emergent effect. In Experiment 1, one group of pigeons (Dual Oddity) learned hue-form arbitrary matching and two oddity relations which shared sample and comparison elements with the arbitrary relations. A second (Control) group learned the same hue-form matching task and a second (form-hue) arbitrary task which, together with hue oddity, shared only the samples with the hue-form relations. On subsequent symmetry probe trials, four Dual Oddity pigeons exhibited higher probe-trial response …

Effects Of Stress, Acute Alcohol Treatment, Or Both On Pre-Pulse Inhibition In High- And Low-Alcohol Preferring Mice, Matthew S. Powers, Julia Chester

Department of Psychological Sciences Faculty Publications

Pre-pulse inhibition of the acoustic startle reflex (PPI) is a measure of sensorimotor gating frequently used to assess information processing in both humans and rodents. Both alcohol and stress exposure can modulate PPI, making it possible to assess how stress and alcohol interact to influence information processing. Humans with an increased genetic risk for alcoholism are more reactive to stressful situations compared to those without a family history, and alcohol may have stress-dampening effects for those with high genetic risk. The purpose of the present study was to examine the effects of stress, acute alcohol exposure, or both on PPI …

Population Structure Of Geosmithia Morbida, The Causal Agent Of Thousand Cankers Disease Of Walnut Trees In The United States, Marcelo M. Zerillo, Jorge Ibarra Caballero, Keith E. Woeste, Andrew D. Graves, Colleen Hartel, Jay W. Pscheidt, Jadelys Tonos, Kirk Broders, Whitney Cranshaw, Steven J. Seybold, Ned Tisserat

Department of Forestry & Natural Resources Faculty Publications

The ascomycete Geosmithia morbida and the walnut twig beetle Pityophthorus juglandis are associated with thousand cankers disease of Juglans (walnut) and Pterocarya (wingnut). The disease was first reported in the western United States (USA) on several Juglans species, but has been found more recently in the eastern USA in the native range of the highly susceptible Juglans nigra. We performed a comprehensive population genetic study of 209 G. morbida isolates collected from Juglans and Pterocarya from 17 geographic regions distributed across 12 U.S. states. The study was based on sequence typing of 27 single nucleotide polymorphisms from three genomic …

Genomic Correlates Of Recombination Rate And Its Variability Across Eight Recombination Maps In The Western Honey Bee (Apis Mellifera L.), Caitlin R. Ross, Dominick S. Defelice, Greg J. Hunt, Kate E. Ihle, Gro Vang Amdam, Olav Rueppell

Department of Entomology Faculty Publications

Background: Meiotic recombination has traditionally been explained based on the structural requirement to stabilize homologous chromosome pairs to ensure their proper meiotic segregation. Competing hypotheses seek to explain the emerging findings of significant heterogeneity in recombination rates within and between genomes, but intraspecific comparisons of genome-wide recombination patterns are rare. The honey bee (Apis mellifera) exhibits the highest rate of genomic recombination among multicellular animals with about five cross-over events per chromatid. Results: Here, we present a comparative analysis of recombination rates across eight genetic linkage maps of the honey bee genome to investigate which genomic sequence features are correlated …

Correction: Comparative Analysis Of Fungal Genomes Reveals Different Plant Cell Wall Degrading Capacity In Fungi, Zhongtao Zhao, Huiquan Liu, Chenfang Wang, Jin-Rong Xu

Department of Botany and Plant Pathology Faculty Publications

Readers are alerted that there is currently a discussion regarding the use of some of the unpublished genomic data presented in this manuscript. Appropriate editorial action will be taken once this matter is resolved.

Background

Fungi produce a variety of carbohydrate activity enzymes (CAZymes) for the degradation of plant polysaccharide materials to facilitate infection and/or gain nutrition. Identifying and comparing CAZymes from fungi with different nutritional modes or infection mechanisms may provide information for better understanding of their life styles and infection models. To date, over hundreds of fungal genomes are publicly available. However, a systematic comparative analysis of fungal …

Associative Concept Learning In Animals, Thomas R. Zentall, Edward A. Wasserman, Peter J. Urcuioli

Department of Psychological Sciences Faculty Publications

Nonhuman animals show evidence for three types of concept learning: perceptual or similarity-based in which objects/stimuli are categorized based on physical similarity; relational in which one object/stimulus is categorized relative to another (e.g., same/different); and associative in which arbitrary stimuli become interchangeable with one another by virtue of a common association with another stimulus, outcome, or response. In this article, we focus on various methods for establishing associative concepts in nonhuman animals and evaluate data documenting the development of associative classes of stimuli. We also examine the nature of the common within-class representation of samples that have been associated with …

Comprehensive Model Of A Single-Screw Expander For Orc-Systems, Davide Ziviani, Ian Bell, Martijn Van Den Broek, Michel De Paepe

International Compressor Engineering Conference

The Organic Rankine Cycle (ORC) system is considered one of the leading technologies for waste heat recovery applications. In order to increase the overall efficiency, design improvements and optimization analyses are necessary. The expander is the key component to convert the thermal energy in useful work. Several volumetric and turbine expanders have been investigated. Among volumetric machines, scroll, twin-screw and vane-type expanders are the main technologies. Recently, a number of experimental studies on single-screw expanders (SSE) have been carried out, demonstrating the feasibility of employing such machine as an ORC expander. The single screw configuration presents a number of advantages …

Heat Transfer Characteristics Of The Non-Uniform Grooved Tube Considering Tube Expansion, Sangmu Lee, Akira Ishibashi, Takuya Matsuda

International Refrigeration and Air Conditioning Conference

A plate-fin heat exchanger is a type of heat exchanger widely used in air conditioners, and tubes and fins are tightly assembled by the mechanical expansion process of tubes. The tube expansion process deforms the grooves inside the tube, and the groove shapes also affect the adhesion between tubes and fins. In this study, the adhesion and heat transfer performance affected by the tube expansion of the non-uniform groove shape tube with different heights are investigated by both analysis and experiments. From the analysis method, it was shown that the contact pressure of non-uniform groove tube is higher than that …

Experimental Comparison Of Working Fluids For Organic Rankine Cycle With Single-Screw Expander, Sergei Gusev, Davide Ziviani, Ian Bell, Michel De Paepe, Martijn Van Den Broek

International Refrigeration and Air Conditioning Conference

This paper describes the behavior of an Organic Rankine Cycle (ORC) fed by a heat source with adaptable temperature and mass flow. For a suitable choice of working fluid, the setting of its evaporation pressure is crucial for the performance of an ORC installation. The higher the evaporation pressure, the higher the cycle efficiency on the one hand, but the lower the energy recovered from the heat source due to a higher outlet temperature on the other hand. An optimum has to be found to achieve maximum net power production. Heat source temperature profiles typical for geothermal and solar applications …

The Efficacy Of Prostaglandin Synthase Inhibition On Attenuating Pressure Overload Induced Cardiac Remodeling, Krishna T. Nagalla

Electronic Theses and Dissertations

Chronic hypertension has long been known to cause left ventricular remodeling. Although previous studies pointed towards inflammation as the pathological driver of cardiac remodeling, the exact mechanistic pathway associated with pressure overload-induced cardiac remodeling remains to be elucidated. In order to address this issue, we designed this study to determine pathways associated with pressure overload induced cardiac remodeling and identify therapeutic targets to attenuate this maladaptive cardiac remodeling. Rats with surgically constricted abdominal aorta were used as an animal model for pressure overload and associated Left ventricular (LV) structure and functional changes were measured by pressure-volume admittance catheterization. Human cardiac …

Cranberry Metabolites With Urinary Anti-Adhesion Activity, Christina M. Coleman

Electronic Theses and Dissertations

The fruit of the American cranberry (Vaccinium macrocarpon Aiton, Ericaceae) is a comfood and a top selling dietary supplement in the U.S. Cranberry juice is traditionally used for the prevention of urinary tract infections (UTIs), many of which are caused by P-fimbriated Escherichia coli. Human urine produced after cranberry juice consumption can prevent E. coli adhesion, but the urinary metabolites responsible for this activity are currently not known. High-molecular weight components of cranberry juice, specifically proanthocyanidin oligomers (PACs), are currently believed to be responsible for the ability of cranberry juice to prevent UTIs. Cranberry PACs can prevent the adherence of …

Structure, Synthesis And Biological Activity Of Harmful Algal Bloom Toxins From Karlodinium Sp. And Exploration Of Microbial Derived Natural Products, Amanda Leigh Waters

Electronic Theses and Dissertations

This work features natural products isolated from both the marine and microbial environments. Part I focuses on the elucidation of toxins from harmful algal blooms (HAB). The HAB dinoflagellate Karlodinium veneficum produces a harmful suite of molecules identified as the karlotoxins (KmTx) that have been implicated in massive fish kills pan-globally. Nine new karlotoxin congeners were isolated from various Karlodinium blooms around the world and utilizing the structure of KmTx2 were characterized using overlaid 2D NMR techniques. Due to the contrasting conformational differences between KmTx and the closely related amphidinols, the absolute configuration of KmTx was further evaluated by extensive …

Evaluating Values, Mindfulness, And Working Alliance: Exploring The Effects Of Short, Specific Techniques, Regan Slater

Electronic Theses and Dissertations

Comfactors research indicates that there is a positive relationship between therapeutic relationship and improved client outcomes. However, little research has been done to examine the nature of this relationship. The current study examined the relationship among values, mindfulness, and working alliance. This study used different specific interventions and examined the interventions' impact on values and mindfulness. The study also examined whether changes in values and mindfulness led to differences in working alliance ratings. Participants were 66 undergraduate students and were randomly assigned to one of three conditions: mindfulness plus values, mindfulness, or control. The participants were then led in a …

Noninvasive Measurement Of Cardiac Stroke Volume Using Pulse Wave Velocity And Aortic Dimensions: A Simulation Study, Charles F. Babbs

Weldon School of Biomedical Engineering Faculty Publications

Background: Concerns about the cost-effectiveness of invasive hemodynamic monitoring in critically ill patients using pulmonary artery catheters motivate a renewed search for effective noninvasive methods to measure stroke volume. This paper explores a new approach based on noninvasively measured pulse wave velocity, pulse contour, and ultrasonically determined aortic cross sectional area. Methods: The Bramwell-Hill equation relating pulse wave velocity to aortic compliance is applied. At the time point on the noninvasively measured pulse contour, denoted th, when pulse amplitude has fallen midway between systolic and diastolic values, the portion of stroke volume remaining in the aorta, and in turn the …

A Tale Of Two Design Contexts: Quantitative And Qualitative Explorations Of Student-Instructor Interactions Amidst Ambiguity, Monica E. Cardella, Patrice Buzzanell, Antonette Cummings, Delean Tolbert, Carla B. Zoltowski

Design Thinking Research Symposium

Designers develop design skills and knowledge through experience and feedback – feedback from colleagues, clients, supervisors, users, stakeholders, the success or failure of a solution, and design educators. In this project, we focus on the feedback provided to mechanical engineering students completing their undergraduate studies and industrial design graduate students during design reviews. The design coaches (educators and industry clients) and design students must negotiate ambiguity in the process. The students must reduce ambiguity in the sense of providing clear details as they communicate their design work, reduce ambiguity in the coaches’ perceptions of the design work quality by providing …

Flood Risk Management: An Illustrative Approach, Natainia S. Lummen, Y Nagayoshi, H Shirozu, T Hokamura, S Nakajo, F Yamada, N Okada

International Institute for Infrastructure Resilience and Reconstruction (I3R2) Conference

Widespread flooding with significant damage in many countries, such as the Philippines in 2013, highlights the ongoing need for effective flood risk management (FRM). This hinges on comprehensive access to and dissemination of information about the elements and the people at risk. Simulations, real-time graphs, and maps illustrate the spatial distribution of flood risks, spatial allocation and dissemination of flood effects, if flood risk reduction measures are not implemented, as well as the benefits to be derived from the effective implementation and maintenance of flood risk management measures not realized. Using precipitation, river water, and tide levels, a real-time monitoring …
