description: The Large Underground Xenon (LUX) experiment operates at the Sanford Underground Research Facility to detect nuclear recoils from the hypothetical Weakly Interacting Massive Particles (WIMPs) on a liquid xenon target. Liquid xenon typically contains trace amounts of the noble radioactive isotopes $^{85}$Kr and $^{39}$Ar that are not removed by the in situ gas purification system. The decays of these isotopes at concentrations typical of research-grade xenon would be a dominant background for a WIMP search exmperiment. To remove these impurities from the liquid xenon, a chromatographic separation system based on adsorption on activated charcoal was built. 400 kg of xenon was processed, reducing the average concentration of krypton from 130 ppb to 3.5 ppt as measured by a cold-trap assisted mass spectroscopy system. A 50 kg batch spiked to 0.001 g/g of krypton was processed twice and reduced to an upper limit of 0.2 ppt.

description: This rewriting of Keck and Mithouard aims to retain the ‘spirit’ of Keck without resorting to categorising national measures into ‘product requirements’ and ‘certain selling arrangements’. The judgment is informed by Senn and Nussbaum’s capability approach and a social justice perspective on the free movement of goods. To this effect, Schøyen’s judgment affirms that only national measures which either negatively impact the competitive position of goods from other Member States or prevent their market access altogether require justification. Thus, the judgment clarifies that product requirements in the sense of Cassis de Dijon are measures having equivalent effect because they impose a double burden on foreign producers. The Sunday trading case law, by contrast, is overturned, like in Keck itself.
Arbitrage: A Critique of the Political Economy of Finance
Creators: name: Hardin, Carolyn
Publisher: name: University of North Carolina at Chapel Hill Graduate School
Year: 2015
Subjects: Communication

description: In the wake of the 2007-09 financial crisis and growing economic inequality fueled by financial activity, it cannot be left to mainstream economists to define and explain finance. This dissertation reexamines finance and the political, social and cultural foundations ignored by economists. In the first chapter, I argue for the importance of arbitrage, a trading strategy defined by buying low priced securities and selling the same securities for higher prices in two different markets. Arbitrage is the conceptual linchpin of modern financial economics but that discipline fails to explain the source of arbitrage profit. In the second chapter, I explore whether Marxist economics can offer a theorization of arbitrage profit. While much of Marxist scholarship too quickly dismisses the significance of finance, there is room for considering arbitrage to be a form of exploitation. In line with innovative Marxist work on finance, I apply a new framework for understanding value to arbitrage in the third chapter. I suggest that arbitrage can be understood as an apparatus of capture in which value founded on social mattering is captured in uneven relations of power. In the fourth chapter, I review the history of arbitrage and suggest that arbitrage is most successful when arbitrageurs can use advantageous differentials in communication networks and/or price stabilizing derivatives contracts to simulate instantaneous trading. A special form of arbitrage I call money machine arbitrage takes place when structural inequalities of price allow for continuous profit making. In the fifth chapter, I offer a final concept necessary for understanding arbitrage as an apparatus of capture: the axiomatic. The axiomatic is the complex system of regulative statements and social relations that enable capture. In the final substantive chapter, I detail the arbitrage in subprime mortgage backed securities in the run up to the 2007-09 financial crisis and sketch some aspects of the axiomatic that can be gleaned from that story. I conclude that the taken-for-granted notion of “risk,” as a necessary way of making wealth and the correlate of return in financial economics, is central to the axiomatic of finance and thus financial profit making.
Novel Topological Effects in Dense QCD in a Magnetic Field

description: We study the electromagnetic properties of dense QCD in the so-called Magnetic Dual Chiral Density Wave phase. This inhomogeneous phase exhibits a nontrivial topology that comes from the fermion sector due to the asymmetry of the lowest Landau level modes. The nontrivial topology manifests in the electromagnetic effective action via a chiral anomaly term $~θF^{μν}\tilde{F}_{μν}$, with a dynamic axion field $θ$ given by the phase of the dual chiral density wave condensate. The coupling of the axion with the electromagnetic field leads to several macroscopic effects that include, among others, an anomalous, nondissipative Hall current, an anomalous electric charge, magnetoelectricity, and the formation of a hybridized propagating mode known as an axion polariton. Connection to topological insulators and Weyls semimetals, as well as possible implications for heavy-ion collisions and neutron stars are all highlighted.

description: This rewriting of Keck and Mithouard maintains the basic underlying philosophy of the Keck judgment but dispenses with the terminology of ‘certain selling arrangements’. Enchelmaier’s judgment squarely overturns the Sunday trading case law by stating that Member States ‘need not justify rules that apply equally in law, and do not entail greater factual burdens for imported than for domestic goods’. The judgment allows for only one exception to this rule, namely that ‘universal bans’ – i.e. national measures prohibiting the marketing of a type or types of product altogether – must be justified because they raise legislative frontier to trade contrary to what is now Article 26(2) TFEU.
Interplay between metformin and serotonin transport in the gastrointestinal tract: a novel mechanism for the intestinal absorption and adverse effects of metformin
Creators: name: Han, Tianxiang
Publisher: name: University of North Carolina at Chapel Hill
Year: 2013

description: Metformin is a widely prescribed drug for Type II diabetes mellitus. Previous studies have shown that this highly hydrophilic and charged compound traverses predominantly paracellularly across the Caco-2 cell monolayer, a well-established model for human intestinal epithelium. However, oral bioavailability of metformin is significantly higher than that of the paracellular probe, mannitol (~60% vs ~16%). Based on these observations, the Thakker laboratory proposed a sponge hypothesis (Proctor et al., 2008) which states that the functional synergy between apical (AP) transporters and paracellular transport enhances the intestinal absorption of metformin. This dissertation work aims to identify AP uptake transporters of metformin, determine their polarized localization, and elucidate their roles in the intestinal absorption and adverse effects of metformin. Chemical inhibition and transporter-knockdown studies revealed that four transporters, namely, organic cation transporter 1 (OCT1), plasma membrane monoamine transporter (PMAT), serotonin reuptake transporter (SERT) and choline high-affinity transporter (CHT) contribute to AP uptake of metformin in Caco-2 cells. Although AP intestinal localization of PMAT, SERT and CHT has been established, the intestinal membrane localization of OCT1 is ambiguous in the literature. In this dissertation work, functional and immunostaining studies showed that OCT1 is localized in the AP membrane of Caco-2 cells and human and mouse intestinal epithelia. Since this dissertation data showed for the first time that metformin is a substrate of SERT, the in vivo role of this transporter in mediating metformin oral absorption was investigated. The SERT-selective chemical inhibitor, paroxetine, decreased metformin systemic AUC0-6h by 9% (p<0.05), and in mSert-/- mice, metformin systemic AUC0-6h was lowered by 6% (p<0.05). Because SERT mediates the reuptake of serotonin which modulates gastrointestinal (GI) functions, its role in metformin-mediated GI adverse effects, such as diarrhea, was investigated in a mouse model. Results showed that metformin induced a 4-fold increase (p<0.001) in intestinal motility, and a 50% increase (p<0.05) in water content of the large intestine. These effects were diminished by serotonin receptor 4 antagonist GR113808, suggesting that metformin could cause GI adverse effects, such as diarrhea, by inhibiting SERT-mediated serotonin re-uptake and subsequent serotonin-induced increased GI motility and water-retention.

description: This rewriting of Keck and Mithouard unequivocally states that the French prohibition on sale at a loss is a measure having equivalent effect, and relies to this effect on the Oosthoek line of case law. Gormley's judgment aims to closely follow the logic of earlier case law, including the Sunday trading case law. The judgment also concludes that a general prohibition of sale at a loss is contrary to Article 30 EEC. Insofar as such a general prohibition takes no account of the reason why the products are offered at a loss, it goes beyond what is necessary and proportionate to ensure fair trading and the protection of consumers. Also in regard to proportionality, the judgment aims to strictly follow the 1980s case law, starting with Cassis de Dijon.
Theory of light-induced effective magnetic field in Rashba ferromagnets

description: Motivated by recent experiments on all-optical magnetization reversal in conductive ferromagnetic thin films we use nonequilibrium formalism to calculate the effective magnetic field induced in a Rashba ferromagnet by a short laser pulse. The main contribution to the effect originates in the direct optical transitions between spin-split subbands. The resulting effective magnetic field is inversely proportional to the impurity scattering rate and can reach the amplitude of a few Tesla in the systems like Co/Pt bilayers. We showthat the total light-induced effective magnetic field in ferromagnetic systems is the sum of two contributions: a helicity dependent term, which is an even function of magnetization, and a helicity independent term, which is an odd function of magnetization. The primary role of the spin-orbit interaction is to widen the frequency range for direct optical transitions.

The Effect of a CPET Familiarization Session on Aerobic Capacity (VO2MAX) in Sedentary Middle-Aged Females
Creators: name: Brooks, Christopher
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: Cardiorespiratory capacity (VO2Max) is assessed by performing a cardiorespiratory exercise test (CPET). Research postulates that a learning effect can compromise the accuracy of the CPET. Healthy populations produce high CPET reproducibility, whereas clinical populations are inconclusive. The purpose of this study was to examine the effect of a familiarization session on aerobic capacity in sedentary middle-aged females. This study recruited 6 female participants ages 35-65. Test protocol consisted of a familiarization session, a VO2Max pre-test, and a VO2Max post-test. VO2Max, respiratory exchange ratio (RER), and maximal heart rate (HRMax) were analyzed using a paired samples t-tests. Relative and absolute VO2Max significantly decreased by -9.68% (p=0.03) and -9.33% (p=0.03), from pre to post. No significant differences were observed for RER and HRMax (p=0.23; p=0.30). This potentially indicates the familiarization effectively mitigated a learning effect; however, due to the small sample size a larger sample is necessary to re-evaluate these preliminary findings.

Hume's treatise and the theory of ideas
Creators: name: Kelahan, Emily M.
Publisher: name: University of North Carolina at Chapel Hill
Year: 2011

description: Hume's Treatise of Human Nature has long been evaluated in terms of the skepticism-naturalism interpretive dichotomy. According to this interpretation, there are two distinct and often diametrically opposed Humes: a skeptic concerned to eradicate dubious metaphysical views and a naturalist concerned to develop a science of human nature. The skeptical Hume applies the theory of ideas developed in Book I of the Treatise to the phenomena he seeks to explain and nearly obliterates them. That leaves the science of human nature weak and without phenomena to explain in Books II and III. The naturalistic Hume, in contrast, is able to develop a robust science of human nature in Books II and III of the Treatise, but does so at the expense of completely abandoning the theory of ideas developed in Book I. In short, the familiar skepticism-naturalism interpretive dichotomy has it that Hume either successfully developed a science of human nature without the theory of ideas or else stubbornly held on to his theory of ideas at the cost of a robust science of human nature. This is a false dichotomy. There is one Hume, not two, who both adheres to the theory of ideas throughout the Treatise and develops a robust science of human nature. Hume accomplished much with little in his Treatise. Most importantly, he demolished extravagant metaphysical theories of various types and developed a robust science of human nature. Both feats were accomplished via his oft criticized, but little understood theory of ideas. Contrary to the prevailing opinion, the theory of ideas stands not in opposition to Hume's naturalistic project of developing a science of human nature, but rather is the foundation of that very project. I develop and defend an interpretation of Hume's theory of ideas according to which it succeeds in eradicating dubious metaphysical views, but also supports, rather than undermines his science of human nature.
The Impact of the Oakland Sugar-sweetened Beverage Tax on Alternatives and Price Promotions
Creators: name: El-Sayed, Osama Mohamed
Publisher: name: University of Illinois at Chicago
Year: 2023

description: This research examines the impact that the Oakland, California, sugar-sweetened beverage (SSB) tax had on noncalorically sweetened beverages (NSBs) and unsweetened beverages as well as on price promotions of SSBs. The first chapter analyzes the effects the Oakland SSB tax on the prices of NSBs and unsweetened beverages using Nielsen retail scanner data with event study and difference-in-differences (DID) estimation models. Sacramento was used as a comparison site. Overall, this study estimated that the prices of beverages increased by 0.60, 0.18, and 0.07 cents per ounce for SSBs, NSBs and unsweetened beverages, respectively, two-years post-tax implementation relative to changes in the comparison site. The second chapter analyzed the impact the Oakland SSB tax on volume sold of NSBs and unsweetened beverages using Nielsen retail scanner data with event study and DID models. Overall, this study estimated that relative to the comparison site of Sacramento, the volume sold of SSBs sold in Oakland decreased by 21 percent two-years post-implementation, while the estimates for the decrease in volume sold for NSBs and unsweetened beverages were not significant. These results provide evidence that the tax did not lead to an increased volume sold of beverages sweetened with artificial noncaloric sweeteners which may be of concern due to their potential negative health effects. The final chapter analyzed the impact of the Oakland SSB tax on price promotions using both Nielsen retail scanner data as well as store audit data. This study again used event study and DID approaches with Sacramento as a comparison site. Overall, this study found that the discount amount for SSBs increased post-tax implementation, with both datasets showing similar results. The results from the retail scanner data and store audit data showed changes in discount amounts of -0.35 and -0.39 cents per ounce, respectively. This suggests a pricing strategy by manufacturers to undermine the tax with increased depth of price promotions. Due to the concerns surrounding noncaloric sweetener consumption (particularly artificial sweeteners) and concerns of the role that price promotions have on obesogenic behavior, these studies provide evidence with important policy implications for SSB taxes that can help improve public health.
Structural dynamics of retroviral genomes

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2012

description: Retroviral RNA genomes form myriad structures that are governed by critical interactions with either the nucleocapsid (NC) protein or the nucleocapsid domain of Gag polyprotein. I have pioneered two powerful technologies, based on SHAPE (selective 2'-hydroxyl acylation analyzed by primer extension), to explore interactions between NC and the RNA genomes of the xenotropic murine leukemia virus related virus (XMRV) and the Moloney murine leukemia virus (MuLV). In the first approach, ultra-sensitive SHAPE, I developed a two-color capillary electrophoresis instrument with low attomole (10-18) sensitivity. New analysis approaches and the high sensitivity of this instrument allowed me to obtain unprecedented single-nucleotide resolution structures from authentic RNA genomes of MuLV and XMRV. In the second approach, time-resolved SHAPE, I used a fast acting SHAPE reagent to reveal the structural biogenesis of NC binding to the MuLV retroviral RNA genome. The data generated using these SHAPE-based technologies allow me to propose detailed mechanisms for both the specific RNA binding and the chaperone activities of NC.

description: We consider two identical bosons propagating on a one-dimensional lattice and address the prob- lem of discriminating whether their mutual on-site interaction is attractive or repulsive. We suggest a probing scheme based on the properties of the corresponding two-particle quantum walks, and show that the sign of the interaction introduces specific and detectable features in the dynamics of quantum correlations, thus permitting to discriminate between the two cases. We also discuss how these features are connected to the band-structure of the Hubbard Hamiltonian, and prove that discrimination may be obtained only when the two walkers are initially prepared in a superposition of localized states.

Accent Placement in Japanese Blends
Creators: name: Broad, Rachel
Publisher: name: University of North Carolina at Chapel Hill Graduate School
Year: 2015
Subjects: subject: Linguistics
subject: FOS: Languages and literature

description: This thesis investigates the factors influencing accent placement in Japanese lexical blends (e.g. gozira ‘Godzilla,’ gorira ‘gorilla’ + kuzira ‘whale’). Previous studies on English blends have claimed that the relative contributions of source words are influenced by factors such as their linear order (Bat-El & Cohen 2012, Gries 2004a,b) or the privileged position of the head (Shaw 2013). I present accent data collected for a corpus of Japanese blends to show that their accent placement is determined by head faithfulness rather than linear order or patterns found in other word formation processes. This work has several implications. First, it provides support for the claim that the position of the head is relevant in blend formation. It also demonstrates that factors influencing blends are cross-linguistically relevant. Finally, it provides evidence that blending is a distinct process and that the internal morphological structure of blends is unlike that of compounds and reduced compounds.
Framing analysis of newspapers coverage of Max Mosley’s Nazi orgy
Creators: name: Aljoura, Loubna
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2009

description: On March 28, 2008, The News of the World, a British tabloid newspaper, published a front page story accompanied by a video saying that Max Mosley, the president of the Federation Internationale de l'Automobile was involved in a depraved Nazi sadomasochistic orgy in a private flat in Chelsea. Explored in this thesis are the story frames and image restoration strategies and postures used by Mosley. Questions of how the news media covered the Mosley story as well as the image restoration strategies and postures evident in Mosley's response are explored using the qualitative content analysis of the news coverage of two British newspapers. This study is significant in that it explored a crisis that occurred by a leader of a private organization whose sexual behaviors were conducted in a private place, and, ultimately, the courts sided with him in protecting his privacy.

On the Line: The Working Lives of Latinos and African Americans in the New South
Creators: name: Ribas, Vanesa
Publisher: name: University of North Carolina at Chapel Hill
Year: 2012

description: This dissertation is an ethnography of a meatpacking plant in North Carolina, where I held a job as a production worker for sixteen months totaling more than 3,500 hours of participant observation between August 2009 and December 2010. I also spent countless hours socializing outside the factory with worker-friends I came to know very well over two years, and conducted twenty-five in-depth interviews with Latina/o and African American workers. In this project, I examine how Latina/o migrants are becoming incorporated in the New South. In particular, I draw attention to how groups develop a sense of their group position in a complex map of hierarchical relations through boundary processes that are structured in key domains, in this case, the workplace. In addition to preconditioning factors such as ethnoracial panoramas in origin countries, the racial/ethnic composition of labor and the authority structure, variation in labor discipline regimes, and social perceptions about the nature of particular kinds of work and the qualities of particular types of workers are all important dimensions that account for how Latinos carve out their place in the New American South. In marked contrast to the fears of some scholars and pundits, and against the conclusions put forth in recent research on the topic of intergroup relations in the U.S. South, African American workers do not talk or behave as if they are especially threatened by economic, political, or cultural competition from Latinos/migrants, and this finding holds regardless of whether African Americans are the majority or minority in a specific department. On the other hand, Latina/os deploy an elaborate array of racialized action that is substantially inflected negatively towards African Americans, that reflects and reinforces ethnoracial boundaries between Latinos and African Americans, represents definitively Latinos' determination to achieve incorporation as nonblacks, and may bolster the hegemony of whiteness in the emerging order.

description: This is the first in a series of papers devoted to the theory of decomposition spaces, a general framework for incidence algebras and Möbius inversion, where algebraic identities are realised by taking homotopy cardinality of equivalences of $\infty$-groupoids. A decomposition space is a simplicial $\infty$-groupoid satisfying an exactness condition, weaker than the Segal condition, expressed in terms of active and inert maps in Delta. Just as the Segal condition expresses composition, the new condition expresses decomposition, and there is an abundance of examples in combinatorics. After establishing some basic properties of decomposition spaces, the main result of this first paper shows that to any decomposition space there is an associated incidence coalgebra, spanned by the space of 1-simplices, and with coefficients in $\infty$-groupoids. We take a functorial viewpoint throughout, emphasising conservative ULF functors; these induce coalgebra homomorphisms. Reduction procedures in the classical theory of incidence coalgebras are examples of this notion, and many are examples of decalage of decomposition spaces. An interesting class of examples of decomposition spaces beyond Segal spaces is provided by Hall algebras: the Waldhausen S-construction of an abelian (or stable infinity) category is shown to be a decomposition space. Note: The notion of decomposition space was arrived at independently by Dyckerhoff and Kapranov (arXiv:1212.3563) who call them unital 2-Segal spaces. Our theory is quite orthogonal to theirs: the definitions are different in spirit and appearance, and the theories differ in terms of motivation, examples and directions.

PARENT INTERACTIVE BEHAVIORS AND LANGUAGE DEVELOPMENT IN CHILDREN WITH AUTISM SPECTRUM DISORDER, FRAGILE X SYNDROME, AND NO DISABILITY
Creators: name: Durante, Genna Rose
Publisher: name: University of North Carolina at Chapel Hill
Year: 2013

description: Language and communication deficits are key features of both autism spectrum disorder (ASD) and fragile X syndrome (FXS). Previous literature has identified parent interaction behaviors as a potential predictive factor in language development for children with and without disabilities, but the relationship between variables is largely unknown for school-age children. In this study, the relationship between parent interactive behavior and language gains was assessed for 66 school-age boys with ASD, FXS and ASD, FXS only, and no disability. Parents interacted with their child in a free play activity and parent behaviors were rated from videotape on the domains of warmth, sensitivity, responsiveness, encouragement of initiative, stimulation value and elaborativeness. Results indicated that parental warmth was a significant predictor of later language gains, while the other domains were not. These results support the linkage of parent interactive behaviors to developmental outcomes during the school-age years.

description: Historians have identified an antebellum Republican “critique of the South” outlining the detrimental effects of slavery on white Southern society and the vital importance of “reconstructing” the white South in the image of the free labor agrarian North following the eventual collapse of slavery. The efforts to follow through with this transformation have historiographically been relegated to the efforts of radical Republicans to reconstruct the ex-Confederacy between 1863 and 1877. This paper argues that Republican strategies and efforts to “reconstruct” the white South were evident during the late antebellum period (1848-1861) applied to the southern counties of Illinois, inhabited chiefly by Southern "poor white” migrants. These efforts to dispel the “Egyptian darkness” of southern Illinois can be seen as an early laboratory of Republican reconstruction strategies.

description: My thesis investigated the microbial diversity and taxonomic composition of hypersaline and non-extreme sediment environments in the Gulf of Mexico, to explore environmental controls on microbial community structure and function. Environmental conditions and resource availability are considered key drivers of microbial diversity and evolution. Extreme environments are traditionally thought to select for more specialized individuals and lower overall diversity, while non-extreme environments foster diverse communities of generalists that are capable of occupying a wider niche. However, extreme environments can also be heterogeneous and complex systems, with a wide variety of energetic resources, providing both challenges and opportunities for diversification. The sediment microbiomes of this study represented natural hydrocarbon seeps, a deep-sea hypersaline anoxic basin (Orca Basin, 26% salinity), Deepwater Horizon (DWH) oil spill-impacted sediments, and Continental Slope background sediments, all collected in November 2010. These samples were analyzed with ~5 million 16S rRNA gene amplicon sequences. Shannon diversity estimates indicated that Orca Basin hypersaline sediments, Continental Slope sediments, and DWH-contaminated surface sediments had similar species diversity, while hydrocarbon seep sediment diversity was significantly lower. UNIFRAC beta diversity analysis indicated that microbial communities inhabiting Orca Basin hypersaline sediments and hydrocarbon seep sediments had taxa unique to each of these site types, while sediments from the Continental Slope and DWH area were not statistically more similar to each other than other sediments. Taxonomic analysis showed that seep cores contained higher abundances of ANME-1 and Candidate Division JS1, while Orca Basin hypersaline sediment-associated sequences were dominated by Marine Group I Archaea, Bacteroidetes and halotolerant Deltaproteobacteria. The microbial composition of the Orca Basin brine was also investigated with 16S rRNA Sanger sequencing, which indicated that Candidate Division KB1-related sequences were the most abundant. A partial KB1 genome sequenced from a single sorted cell revealed that its proteome is dominated by acidic amino acids; therefore, KB1 likely incorporates potassium ions for osmoregulation. KB1 also contains complete enzymes for the acetyl-CoA pathway, and has genes consistent with a glycine betaine transporter cassette as well as genes that may allow for use of glycine betaine as an energy source.

description: In contrast to the seminal weak localization prediction of a non-critical Hall constant ($R_{H}$) at the Anderson metal-insulator transition (MIT), $R_{H}$ in quite a few real disordered systems exhibits both, a strong $T$-dependence and critical scaling near their MIT. Here, we investigate these issues in detail within a non-perturbative "strong localization" regime using cluster-dynamical mean field theory (CDMFT). We uncover $(i)$ clear and unconventional quantum-critical scaling of the $γ$-function, finding that $γ(g_{xy})\simeq$ log$(g_{xy})$ over a wide range spanning the continuous MIT, very similar to that seen for the longitudinal conductivity, $(ii)$ strongly $T$-dependent and clear quantum critical scaling in both transverse conductivity and $R_{H}$ at the MIT. We find that these surprising results are in comprehensive and very good accord with signatures of a novel kind of localization in disordered NbN near the MIT, providing substantial support for our "strong" localization view.

Novel fluoroelastomers composed of tetrafluoroethylene and vinylidene fluoride oligomers synthesized in carbon dioxide for use in soft lithography to enable a platform for the fabrication of shape- and size-specific, monodisperse biomaterials

description: Fluorinated elastomers are materials with tremendous utility that have found use as minimally adhesive mold materials in soft lithography. The first objective of this research involved the synthesis of novel functional, fluorinated oligomers in supercritical carbon dioxide (scCO2) and the fabrication of the resulting fluorooligomers into solid elastomers using free radical crosslinking chemistry. Commercially available fluoroelastomers are typically synthesized in aqueous media using fluorinated surfactants or in non-aqueous conditions using fluorinated solvents. This research effort focused on the synthesis of low molecular weight oligomers consisting of tetrafluoroethylene (TFE) and vinylidene fluoride (VF2) with a cure site comonomer in scCO2 at low temperatures. Using CO2 as a polymerization medium allows for safe handling of TFE, is environmentally responsible by mitigating the typical generation of halogenated, organic, or aqueous waste, and circumvents the use of fluorinated surfactants as these copolymers are soluble in CO2. Investigations included characterizing the fluorinated oligomers and the solid elastomeric materials using NMR, DSC, TGA, GPC, IR, and via surface and mechanical property analysis. The second objective of this research included the use of fluoroelastomers as minimally adhesive mold materials in soft lithography applications using the Particle Replication In Non-wetting Templates (PRINT) technology for the fabrication of protein particles of discrete size and shape. Lyophilized protein particles are generally highly disperse in particle size, tend toward aggregation, and are often made through complicated processes. In attempts to engineer mono-disperse protein particles, the use of wet-milling, spray-freeze-drying, micro-emulsion, or super critical fluid methods have been reported. The PRINT process enables a gentle, facile route to mono-disperse particles composed of protein with and without cargo. This research objective included fabricating protein PRINT particles of varying sizes, shapes, and compositions (e.g., Abraxane, albumin, tranferrin, insulin, interferon-beta, hemoglobin, trypsin, horseradish peroxidase, and IgG). Several biophysical characterizations were performed to verify the protein structure was not significantly altered during the PRINT process, including SEM, FTIR, fluorescence microscopy, and CD. Furthermore, ELISA and enzymatic activity assays were performed to investigate biological integrity and function of all proteins. The PRINT technology was found to be a gentle method to create nanoparticles of biologically relevant proteins.
Essays in microfinance- and social network-driven marketing at the base of the pyramid

description: In the past thirty years, microfinance has innovated the provision of financial services to microenterprises (businesses with five or fewer employees), growing aggressively to a USD $50 billion industry. A marketing lens gives us the empirical and theoretical foundations to understand this field, providing the tools to synthesize the ideas of social capital, microfinance, and networks into managerially important insights. I explore these concepts using a novel dataset assembled from surveys, personal networks, interviews, administrative banking data, and a randomized control trial (RCT) of microentrepreneurs in Kenya, where microenterprises are estimated to represent over 20% of the country’s total employment. Essay one builds on the relationship marketing literature’s identification of commitment as critical to maintaining successful business-to-consumer relationships. I find a positive relationship between household consumption and client commitment – however, this includes not only commitment to the firm, but also to their loan peers. This has implications for MFI client strategy, motivation to cultivate both positive client commitment towards the firm as well as social capital within the client’s intra-firm network. The second essay tackles an endogenous question: which came first, social capital or financial success? Although social capital is commonly accepted in economic development theory as a key driver of financial success, the methodological difficulty of studying its causal impact leave a gap in the literature. I use a RCT to administer a financial training, providing a channel to improve financial success. While we find that the training does significantly impact financial literacy and MFI financial measures, we do not find any moderating impact of baseline social capital on financial outcomes. This study provides a counterargument to the conventional wisdom that social capital increases efficiency of entrepreneurial information acquisition and application. These dissertation results provide an alternative view about the importance of social capital at the BoP: although social capital is a part of financial success, it doesn’t appear to have the causal impact previously theorized. Through an innovative dataset and rigorous experimental methods, this dissertation provides one of the first quantitative, network-based studies of social capital at the BoP. Implications for managers, policy makers, and researchers are discussed.

description: Decomposition spaces are simplicial $\infty$-groupoids subject to a certain exactness condition, needed to induce a coalgebra structure on the space of arrows. Conservative ULF functors (CULF) between decomposition spaces induce coalgebra homomorphisms. Suitable added finiteness conditions define the notion of Möbius decomposition space, a far-reaching generalisation of the notion of Möbius category of Leroux. In this paper, we show that the Lawvere-Menni Hopf algebra of Möbius intervals, which contains the universal Möbius function (but is not induced by a Möbius category), can be realised as the homotopy cardinality of a Möbius decomposition space $U$ of all Möbius intervals, and that in a certain sense $U$ is universal for Möbius decomposition spaces and CULF functors.

description: Following on our earlier work on leading-logarithmic (LLR) resummations for the properties of jets with a small radius, R, we here examine the phenomenological considerations for the inclusive jet spectrum. We discuss how to match the NLO predictions with small-R resummation. As part of the study we propose a new, physically-inspired prescription for fixed-order predictions and their uncertainties. We investigate the R-dependent part of the next-to-next-to-leading order (NNLO) corrections, which is found to be substantial, and comment on the implications for scale choices in inclusive jet calculations. We also examine hadronisation corrections, identifying potential limitations of earlier analytical work with regards to their $p_t$-dependence. Finally we assemble these different elements in order to compare matched (N)NLO+LLR predictions to data from ALICE and ATLAS, finding improved consistency for the R-dependence of the results relative to NLO predictions.
