Comparative genomic analysis identifies common tumorigenesis-associated pathways modulated by exposure to low dose arsenic or cadmium
Creators: name: Benton, Margaret Ann
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2010

description: While arsenic and cadmium are well known to cause adverse health effects at high doses, the molecular impact resulting from exposure to environmentally relevant doses of these metals remains largely unexplored. In this study, we examined the effects of in vitro exposure to either arsenic or cadmium in human TK6 lymphoblastoid cells using genomics and systems level pathway mapping approaches. A total of 167 genes with differential expression were identified following exposure to either metal with surprisingly no overlap between the two. The gene sets altered by low dose metal exposure were overlaid on to protein-protein interaction maps to identify metal-induced transcriptional networks. Both metal-induced networks were significantly enriched for tumorigenesis-associated proteins, as well as numerous other biological processes, including inflammatory response and cell signaling. These results highlight that even at low levels of exposure both metals can dramatically influence the expression of important cellular pathways.

description: The Future Migration Scenarios for Europe (FUME) project aims to fill the knowledge gap in existing research concerning determinants for migration by investigating and evaluating migration patterns, motivations, and modalities at multiple geographical scales, from international through regional to local, and imagining possible futures. The population and migration projections, which aim to shed some light on the complex interactions of the drivers of migration and the migration outcomes, lay at the project's core. While migration projections require assumptions on the size and the characteristics of the future populations and assumptions on the future development of migration drivers, migration scenario narratives provide the qualitative reasoning behind these assumptions. A considerable amount of literature has been published on global and migration scenarios in recent decades. Central to the migration scenarios and narratives are the concepts of migration drivers and migration dynamics. Demographic, economic, technological, social, political, and environmental developments and complex interrelations between these domains are considered essential in creating plausible future migration developments. This report provides a set of internally consistent and evidence-based qualitative scenario narratives. The narratives are built on consistent demographic, socio-economic, environmental and political alternate futures generated for the EU and developing countries based on the qualitative and quantitative evidence gathered in the FUME project. Each narrative describes the future for the EU and developing countries in the short-term until 2030 and in the long-term between 2030 and 2050. These alternative futures are complemented by the potential changes in the future migratory demand and pressure from the expert survey conducted in the project and the characteristics of future migrants from the Delphi survey.

description: For a log scheme locally of finite type over $\mathbb{C}$, a natural candidate for its profinite homotopy type is the profinite completion of its Kato-Nakayama space. Alternatively, one may consider the profinite homotopy type of the underlying topological stack of its infinite root stack. Finally, for a log scheme not necessarily over $\mathbb{C}$, another natural candidate is the profinite étale homotopy type of its infinite root stack. We prove that, for a fine saturated log scheme locally of finite type over $\mathbb{C}$, these three notions agree. In particular, we construct a comparison map from the Kato-Nakayama space to the underlying topological stack of the infinite root stack, and prove that it induces an equivalence on profinite completions. In light of these results, we define the profinite homotopy type of a general fine saturated log scheme as the profinite étale homotopy type of its infinite root stack.

The Effect of a Vitamin A Enriched Diet on Murine Contact Hypersensitivity Tests
Creators: name: Deshpande, Sonali R.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1993

description: Murine assays such as the mouse ear swelling test (MEST) and the local lymph node assay (LLNA) are promising alternatives to guinea pig models for the identification of contact sensitizers, yet there has been controversy over the effectiveness of these assays for the detection of weak and moderate sensitizers. Much work has been done to improve the sensitivity of the MEST. In particular, the addition of a vitamin A (VAA) enriched diet has been useful. This report further validates the use of this diet in the MEST by using a known weak sensitizer, eugenol, and a purportedly weak sensitizer, Trimelletic Anhydride (TMA). The vitamin A enriched diet improved the sensitivity of the assay such that contact sensitizing activity was identified using 20% Eugenol, a concentration which did not give positive results when vitamin A diet was omitted from the assay. There was no effect of the VAA diet on detection of TMA (25%) which was found to be a strong to moderate sensitizer. Enhanced MEST sensitivity to 20% eugenol was demonstrated in mice held on the diet for 1, 2 or 3 weeks. In contrast, 20% eugenol was not detectedin the MEST when mice were maintained on the diet for 4 weeks. VAA has been reported to increase the numbers of Langerhans cells (antigen presenting cells) in the skin which could in turn enhance the cellular immune response. Since the LLNA relies on H^3-thymidine incorporation by proliferating T-cells during the induction phase, we have studied the potential of the VAA diet to enhance the sensitivity of the LLNA. Results in this report indicate that the VAA enriched diet significantly increased the assays sensitivity to eugenol and TMA (i.e. proliferation occurred) at concentrations where none was observed in mice maintained on normal chow. Previous work with formalin, glutaraldehyde and an azo dye have shown similar results. It was also demonstrated that maintenance on a vitamin A diet for 3 weeks prior to initiating the sensitization procedure was optimal. These results indicated that like the MEST, addition of a VAA diet improves the sensitivity of the LLNA a quick, objective and relatively inexpensive screen for detecting moderate and weak contact sensitizers. Using these sensitive tests, a risk assessment approach for contact sensitization has been suggested.

description: The purpose of this study is to investigate how Mississippi Gulf Coast Creoles perceive language differences in their home area. A pile-sort task was carried out in which respondents were given stacks of cards with local communities written on them and instructed to stack together the regions where people “talk the same.” Once the piles were made, the fieldworker discussed their sortings with the respondents. The stacks were analyzed by means of a hierarchal agglomerative cluster analysis and non-parametric multidimensional scaling with k-means cluster analysis overlays to extract the perceived dialect areas. The groupings reveal that respondent strategies are based on geographical concerns (e.g. distance), linguistic facts, and related ethnic identity beliefs. These areas were also analyzed using qualitative data from the post-pile-sort discussion and revealed the respondent’s attitudes, stances, and presupposed and implicated meanings that aided in the interpretation of their perceptions and attitudes with regard to local language ideology in the region. The results show that there are six perceived dialect areas on the Mississippi Gulf Coast. The Principal Component Analysis revealed that urban and rural is the biggest differentiation among dialect groups, followed by Frenchness and Southernness.

A Study of Travel Modes of Elementary School Students in Chapel Hill, NC

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2007

description: The proportion of youth who are overweight has more than doubled in the last 20 years, in part causing health professionals to declare an obesity epidemic in the United States. One of the main factors responsible for the epidemic of overweight and obesity is the sharp decline in physical activity and the corresponding increase in sedentary behavior in youth. Active Living by Design is a nation wide program that establishes innovative approaches to increase physical activity through community design, public policies and communications strategies. Chapel Hill, NC, was selected as one of the 25 Active Living by Design Community Partnerships in October 2003. Since then, their partnership has worked to promote physical activity and active living inchools. In September2004, take-home questionnaires were distributed to all students at Ephesus Elementary, Estes Hills Elementary, Phillips Middle and Scroggs Elementary schools. The surveys were designed to investigate children's commuting habits and to gauge parents' perceptions of the traffic environment and concerns regarding their children's transportation behaviors. This research focused on a statistical and quantitative analysis of the data obtained from those surveys. The analysis included fitting 2 different statistical models to the data, one aimed at explaining why some children always walked or hiked and the other aimed at explaining why some children never walked or hiked to school; by implication, these models provided information on why children sometimes walked or hiked. The results of the logistic regression (logit) models along with supporting information from the questionnaires were used to explore policy alternatives for increasing the numbers of elementary school walkers and bikers in Chapel Hill. Findings suggest that structural interventions such as speedbumps to slow traffic and improved sidewalks will do little to increase walkers and bikers. Rather, the main needs are to dissuade parents from driving their children to school and not to rely on driving as the main mechanism for preventing children from arriving late.
Primordial $^4\text{He}$ constraints on inelastic macro dark matter revisited

description: At present, the best model for the evolution of the cosmos requires that dark matter make up approximately $25\%$ of the energy content of the Universe. Most approaches to explain the microscopic nature of dark matter, to date, have assumed its composition to be of intrinsically weakly interacting particles; however, this need not be the case to have consistency with all extant observations. Given decades of inconclusive evidence to support any dark matter candidate, there is strong motivation to consider alternatives to the standard particle scenario. One such example is macro dark matter, a class of candidates (macros) that could interact strongly with the particles of the Standard Model, have large masses and physical sizes, and yet behave as dark matter. Macros that scatter completely inelastically could have altered the primordial production of the elements, and macro charge-dependent constraints have been obtained previously. Here we reconsider the phenomenology of inelastically interacting macros on the abundance of primordially produced $^4\text{He}$ and revise previous constraints by also taking into account improved measurements of the primordial $^4\text{He}$ abundance. The constraints derived here are limited in applicability to only leptophobic macros that have a surface potential $V \gtrsim 0.5\,$MeV. However, an important conclusion from our analysis is that even neutral macros would likely affect the abundance of the light elements. Therefore, constraints on that scenario are possible and are currently an open question.

Residential Water Consumption in the OWASA Service Area: Chapel Hill and Carrboro, North Carolina
Creators: name: Kauffman, Rebecca M.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2001

description: The Orange Water & Sewer Authority (OWASA) contracted with the Department of Environmental Sciences & Engineering to conduct a two-stage study involving current water consumption. This study is intended to help OWASA determine conservation and pricing strategies in accordance with their Comprehensive Water & Sewer Master Plan. The goal in Phase I, described in this technical report, is to understand residential consumption. Preliminary screening and analysis was performed in Phase I that will help guide the content in Phase II. This report addresses patterns of residential water consumption and uses a linear regression model to identify factors related to consumption and assess effects of passive conservation. Residential users consume an average of approximately 6,000 gallons per month per household. Single family households use almost 60 percent more water than multi-family housing units. Summer outdoor use accounts for approximately 55 to 60 percent of the total use for multi and single family households, respectively. Factors significantly associated with monthly consumption include the assessed value of the house, property area, type of housing unit, whether or not the house was constructed before 1994, average monthly temperature, and the number of days of precipitation per month. Passive conservation, which is the reduction in consumption due to water-saving devices, was prompted by the plumbing code regulations in 1994 that require new homes to contain more efficient fixtures. Houses constructed before 1994 consume approximately 500 gallons per month per household more than those built after the 1994 regulations. Further work is needed to verify results from Phase I. Some of the tasks may include collecting additional secondary data on house construction date, collecting primary data via a household survey, and assessing the validity of the Aquilium database.
A Comparison of Three Dispersion Media on the Physicochemical and Toxicological Behavior of TiO2 and NiO Nanoparticles
Creators: name: Gutierrez, Erika Rasche

Year: 2013

description: Nanomaterials represent a burgeoning field of technological innovation. With the onset of environmental release associated with nanomaterial manufacture and proliferation, the concomitant effects on human health remain unknown and polemic. Agglomeration of nanomaterials in biologically relevant media further complicates dosing in toxicological study. Objective: To compare the effects of dispersion techniques on the physicochemical and toxicological dosimetry of TiO2(<50nm) and NiO(<20nm) nanoparticles. Methods: Three media were prepared for A549 and 16hbe14o cells with varying concentrations of -TiO2 and NiO nanoparticles. Physicochemical and toxicological effects were analyzed with dynamic light scattering, ICP-MS, SEM, TEM, ELISA, and stimulation of A549 cells with nanoparticles for 4 and 24 hours followed by analysis of inflammatory and oxidative stress markers with RT-PCR. Dispersion media physicochemical properties affect toxicological endpoints. In vitro nanotoxicology models that use re-suspension methods of exposure yield inconsistent biological results due to physicochemical transport processes.

description: In this paper we present a detailed analysis of the Electroweak Precision Observables (EWPO) in composite Higgs models based on the coset $SO(5)/SO(4)$. In our study we include both the fermionic top partners and the spin-1 resonances and consider their possible interplay as well. In order to achieve calculability we use the assumptions of i) partial Ultra Violet Completion (PUVC) following arXiv:1109.1570 and, ii) absence of sizeable effects from physics above the cut-off. Apart from the EWPO, we also take into account the constraints from the top quark, $Z$ and the Higgs boson masses whenever they can be predicted in terms of the model parameters. After presenting our analytic results (often, in certain limits) and discussing their symmetry properties, we also perform detailed fits of the model parameters following the Bayesian approach. We show the posterior probability distributions of the parameters in various scenarios and provide with analytic understanding whenever possible. We find that in certain cases the EWPO allow the compositeness scale to lie well below $1$ TeV. Moreover, fermionic top partners of mass around $1$ TeV and spin-1 resonances of mass around $2-3$ TeV are consistent with the precision data.

Effects of Nutrient Loading Rate and Greentree Management on Nutrient Removal in a Bottomland System Receiving Municipal Wastewater
Creators: name: Tzeng, Shichin
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1989

description: Nitrate, total-N, filterable reactive phosphorus, and total-P loading rates were calculated and the effectiveness of nutrient removal was assessed from June 1987 to March 1989 in the New Hope Creek system, a bottomland system receiving municipal wastewater from Durham Co., North Carolina. The study site was recently modified by construction of three dams. The resulting subimpoundments, flooded from November 1988 through February 1989, were built as greentree management areas for wintering waterfowl. The effectiveness of nutrient removal was determined by calculating the percentage of effluent nutrient changes and nutrient flux coefficient, corrected for dilution, at stations downstream of the outfall. During the study period, nitrate and total-N loading rates averaged 9.79 and 11.8 g*m^-2.day^-1; phosphate and total-P averaged 1.65 and 1.57 g*m^-2.day^-1, respectively. Nutrient loadings were reduced greatly during greentree inundation, which expanded the contact area between the effluent nutrients and the system from approximately 45000 m^2 to 680000 m^2. Results of nutrient removal indicated that nutrient removal capabilities of the New Hope Creek system were poor. The system had no effect on the fluxes of nitrogen species during the study period. Net gains of filterable reactive phosphorus to the New Hope Creek water were found most of time, but the system had no effect on the fluxes of filterable reactive phosphorus during greentree inundation. The system did not affect the fluxes of total-P, except during greentree inundation when there were net gains of total-P from the system to the water. During the study, flux coefficients for the major nutrient species in the New Hope Creek water were significantly affected by the nutrient loading rates, except for total-P. Nutrient removal decreased as nutrient loading rates increased, that is, nutrient transport was into the water at higher loading rates. However, due to the deficit in precipitation during the study, results are only applicable for the New Hope Creek system in a dry year.

Laboratory and Field Comparisons of Air Sampling Methods for 1,6-Hexamethylene Diisocyanate
Creators: name: Thomasen, Jennifer M.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2007

description: The published literature on evaluation of sampling devices and methods for determining workers' exposure to diisocyanate-containing compounds is conflicting and most of the methods have not been tested in both a laboratory and occupational setting. The objective of this study was to evaluate the performance of commonly used sampling devices for 1,6-hexamethylene diisocyanate (HDI) in both the laboratory and occupational field setting. Polystyrene (PS) and polypropylene (PP) cassettes with treated filters, IOM cassettes, OSHA Method 42 cassettes, and IsoChek® cassettes were evaluated in the laboratory setting. Recovery of HDI mass using either toluene (HDI/TOL) or acetonitrile (HDI/ACN)as solvents was determined. In the laboratory, the IOM and 25-mm PP cassette types recovered the most HDI mass (>77%) while the IsoChek® performed the worst recovering <16% of HDI mass. The reactivity of HDI with different filter housings and sampling materials was determined by spiking pure HDI, HDI/TOL, or HDI/ACN onto filter housings and sampling materials. Pure HDI and HDI/TOL were most reactive with PS and the reaction of HDI with sampling materials was amplified by the presence of a non-polar solvent (i.e., TOL). The sampling efficiencies of 1- and 2-stage PP and PS cassettes were compared to an impinger in the occupational setting by spraying fast- or slow-drying clear coat containing HDI polyisocyanates above the samplers. No significant difference was observed in HDI monomer recovery between PP and PS samplers. However, significant difference (p<0.05) was observed in the recovery of HDI oligomers between 1- and 2-stage cassettes and between fast- and slow-drying clear coats. The 1-stage cassettes recovered more HDI monomer and oligomer when a fast-drying clear coat was applied. In summary, this study provides evidence that sampling losses may occur due to the reactivity of HDI with sampling materials or with polyols in automotive paint overspray. We also demonstrate the importance of performing experiments in both the laboratory and occupational setting. Experiments performed in the occupational setting indicate that the type of clear coat used during spray-painting activities should be considered when selecting a sampler for monitoring exposure to HDI.
Assessing Data Quality for Life Cycle Assessment

Year: 1993

description: Life cycle assessment (LCA) is an analytical decision support tool used to identify and evaluate opportunities to reduce environmental impacts associated with products, processes, packages, materials, activities. LCA has three primary components: development of a quantitative life cycle inventory (LCI), conduct of an impact assessment (lA), and evaluation and implementation of environmental improvements. LCAs typically use a multitude of data sources and types to draw important conclusions about products and processes. Most LCAs released to date have included minimal data quality evaluations. This document uses the concepts of quality assurance/quality control (QA/QC), decision analysis, and the data reliability indicator system developed by Kollig, to develop a framework for the assessment of LCA data quality. The framework includes a quantitative scoring system to evaluate LCA parameters against certain data quality indicators, and a system of data quality worksheets and a data quality matrix to translate the information into a usable format.

Following removal of duplicates and ineligible articles through screening of titles and abstracts, full texts of potentially eligible studies will be assessed for eligibility. Eligible studies will be critically appraised for methodological quality, by two independent researchers. A standardized tool will be used to extract key data from included studies. A critical narrative synthesis will be completed, and if data allow, a meta-analysis will be undertaken. Systematic review registration number (For Protocols ONLY): The review will be registered with the OSF.
An Evaluation of Leafspot Advisory and Integrated Pest Management Adoption Among Peanut Farmers in Northampton County, North Carolina
Creators: name: Hitzig, Robert
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1984

description: Leafspot advisory (LSA) is an integrated pest management (IPM) strategy designed to reduce the number of sprays necessary to control the spread of the peanut leafspotting pathogen, Cercospora arachidicola. It is in use in nine North Carolina counties and has been used in Northampton County since 1983. Thirty-one peanut farmers were interviewed over the telephone to determine the level of LSA and IPM adoption in Northampton County. The survey revealed that 52 percent of the farmers used the advisory, saving an average of 2.4 sprays/year. Only 32 percent used other IPM strategies. The level of farmer concern about the harmful effects of pesticides was also measured. Farmers were worried about the effects of pesticides on fish and wildlife but their level of concern was not found to be associated with the adoption of pesticide reducing technologies. LSA, as one IPM strategy, was found to be successfully implemented in comparison to a complete IPM program, but, extension specialists can make improvements. Recommendations are made for increasing the percentage of farmers adopting pest management innovations.

description: Environmental impacts and regulations in North Carolina related to closing unused swine waste lagoons were examined. There are over 3,000 swine operations in North Carolina, each raising more than 250 hogs, which use anaerobic waste lagoons to treat and store their waste. Most of the facilities in the state with populations of 1, 000 or more hogs began operation after 1990. Environmental and public health risks, although not as yet quantified, are associated with anaerobic lagoons and until these impoundments are closed the risks remain. Four county health boards and one county commission in the state have adopted rules mandating lagoon closure of certain swine operations within their jurisdiction when the facility ceases production. Four of these counties also have bonding requirements to ensure funds for completing the closure. One hundred-two of the existing swine operations in the state are subject to these county provisions. All other swine operations in the state rasing more than 250 hogs are subject only to state requirements - which allow facilities that are going out of business to either close their lagoon or maintain it under a waste management plan. The North Carolina Agriculture Cost Share Program is the only program in the state which provides financial assistance for closing lagoons and is restricted to closing lagoons which are abandoned or located at operations going out of business. This program will not be able to fund closure of all inactive swine waste lagoons in the state. Based on the information reviewed, the state should develop a plan to address the issues related to closing unused lagoons. Specific items which deserve consideration include options for holding swine operations financial responsible for closure, evaluating current closure standards, refining cost-shared expenditures, and providing clear statutory authority for mandating lagoon closure.

description: Photoacoustic imaging for biomedical application has attracted much research in recent years. To date, most of the work has focused on pulsed photoacoustics. Recent developments have seen the implementation of a radar pulse compression methodology into continuous wave photoacoustic modality, however very little theory has been developed in support of this approach. In this thesis, the one-dimensional theory of radar photoacousticsfor pulse compressedlinear frequency modulated continuous sinusoidal laserphotoacoustics is developed.The effect of the chirp parameters on the corresponding photoacoustic signal is investigated, and guidelines for choosing the chirp parametersfor absorber profilometric detectionare given based on the developed theory and simulations. Simulated results are also compared to available experimental results and show a good agreement.
Recycling the Operating Room: An Analysis of the Sustainability of Medical Technology Transfers to Less Developed Nations

description: In an age of growing disparity between rich and poor nations, unsustainable transfers of medical technology from the developed to the less developed world are an undesirable source of waste and inefficiency. Various theories why these transfers fail are discussed in this paper. Hypotheses that defend the importance of local user's input into the acquisition decision were supported by a small case-control study. In 42 examples of technology transfers to 9 less developed countries statistically significant associations, (p<.05 as calculated by odds ratios), were shown between sustainability and local profit, effective maintenance, lack of significant opportunity costs, local acquisition choice, (not donated), urban location and the use of technology assessment. Large odds ratios, but not statistically significant, (p>.05) associations were seen between sustainability and local funding, appropriateness and new technologies. No relationship was seen between sustainability and customization, risk, benefit, original idea, supervision or supply responsibility. By a separate measure no relationship between sustainability and the classic demographic indicators of GDP, infant mortality and % foreign funding for healthcare was seen. Implications of current policies regarding medical technology transfers are discussed and a suggestion for an allocation system modeled after a program currently in place in the United States for distributing human organs for transplantation is suggested.

RNA-Binding Protein HuD as a Potential Therapeutic Target for Spinal Muscular Atrophy

description: Spinal muscular atrophy is caused by mutation of the SMN1 gene resulting in the selective loss of spinal cord motor neurons. HuD has been shown to interact with SMN and to localize to RNA granules along axons. In conditions where SMN is decreased, like in SMA, HuD’s localization to RNA granules affected. Overexpression of HuD in an SMA cell culture model was shown to rescue SMA-like axonal defects. Here, existence of a signaling pathway downstream of PKC leading to the activation of HuD was investigated in MN-1 cells. Stimulation of this pathway using a pharmacological agonist of PKC increased HuD levels and enhanced its binding to GAP-43 and Tau mRNAs. An scAAV9 viral expression system to overexpress HuD in vivo was established, laying the foundation for the next phase of the study. Overall, modulating HuD expression and activity would be beneficial and could constitute an attractive therapeutic approach for SMA.
On ambiguity in knot polynomials for virtual knots

description: We claim that HOMFLY polynomials for virtual knots, defined with the help of the matrix-model recursion relations, contain more parameters, than just the usual $q$ and $A = q^N$. These parameters preserve topological invariance and do not show up in the case of ordinary (non-virtual) knots and links. They are most conveniently observed in the hypercube formalism: then they substitute $q$-dimensions of certain fat graphs, which are not constrained by recursion and can be chosen arbitrarily. The number of these new topological invariants seems to grow fast with the number of non-virtual crossings: 0, 1, 1, 5, 15, 91, 784, 9160, ... This number can be decreased by imposing the factorization requirement for composites, in addition to topological invariance -- still freedom remains. None of these new parameters, however, appear in HOMFLY for Kishino unknot, which thus remains unseparated from the ordinary unknots even by this enriched set of knot invariants.

Collapse of the Hunnic Empire: Jordanes, Ardaric and the Battle of Nedao

description: This thesis examines the evidence surrounding the Battle of Nedao, an engagement between Ardaric, leader of the Gepids and other rebelling tribes, and Ellac, the eldest son of Attila. It argues against the claim that, after Attila’s death, it was the sons of Attila who ruined the Hunnic empire through civil war. Instead, the political crisis which inevitably led to the battle was brought about by Attila’s murdering of his brother and co-king, Bleda, in 445 and his intestate death in 453. If there was civil war between Attila’s sons, it did not occur until after Nedao. Furthermore, Ardaric was not of Royal Hunnic status fighting for succession at Nedao. He was, instead, one of the leaders of a rebellion that was not limited to Germanic tribes. The thesis focuses primarily on one source, Jordanes, since his Getica is the only known account of the battle which is not mentioned by any other contemporary source. The paper analyzes both Jordanes as an author and the language in his Getica, finding him not to be the semiliterate copyist of Cassiodorus, but instead underlines his own agency in the organizing of the work. From this broader understanding of Jordanes and Getica, it furthermore determines that he may, in fact, harbor an anti-Gepid sentiment towards the Gepid kingdom of his own day in the sixth century. Jordanes may, therefore, be anachronistically ascribing strength and importance to the Gepids’ role at Nedao, as Gepid-Constantinopolitan tension reached its zenith at the time he composed his work, thereby critically affecting our interpretation of the Battle of Nedao narrative.
