description: The gauge action of the Lie group $G$ on the chiral WZNW phase space ${\cal M}_{\check G}$ of quasiperiodic fields with $\check G$-valued monodromy, where $\check G\subset G$ is an open submanifold, is known to be a Poisson-Lie (PL) action with respect to any coboundary PL structure on $G$, if the Poisson bracket on ${\cal M}_{\check G}$ is defined by a suitable monodromy dependent exchange $r$-matrix. We describe the momentum map for these symmetries when $G$ is either a factorisable PL group or a compact simple Lie group with its standard PL structure. The main result is an explicit one-to-one correspondence between the monodromy variable $M \in \check G$ and a conventional variable $Ω\in G^*$. This permits us to convert the PL groupoid associated with a WZNW exchange $r$-matrix into a `canonical' PL groupoid constructed from the Heisenberg double of $G$, and consequently to obtain a natural PL generalization of the classical dynamical Yang-Baxter equation.

description: In this paper, two key questions are asked: why has the GATT/WTO worked in terms of multilateral tariff reduction and promotion of global trade, and to what extent will it act as a constraint on economic nationalism? To answer these two questions, three themes are laid out in the paper: first, the seminal economic model rationalizing the economic logic of the GATT/WTO is assessed; second, the perceived relevance of the GATT/WTO in a world of increasing regionalism is discussed; and third, the robustness of the GATT/WTO legal framework and dispute resolution mechanism is evaluated. The key conclusion of the paper is that the underlying economic logic of the GATT/WTO is still relevant, but that enforcement of the cooperative agreement will likely be placed under significant strain with threat of increased protection, and even a potential trade war.

description: In multivariate analysis, principal component analysis is a widely popular method which is used in many different fields. Though it has been extensively shown to work well when data follows multivariate normality, classical PCA suffers when data is heavy-tailed. Using PCA with the assumption that the data follows a stable distribution, we will show through simulations that a new method is better. We show the modified PCA can be used for heavy-tailed data and that we can more accurately estimate the correct number of components compared to classical PCA and more accurately identify the subspace spanned by the important components.

description: The goal of this project was to synthesize a novel, flame-resistant, intumescent polymer that meets or exceeds industry standards in terms of strength, cost, versatility, and biodegradability. Chitosan, an intumescent material, was used to prepare a thermoplastic extruded polymer. Clay or metal salt additives were used to improve charring or viscosity properties. Extruded polymers underwent a wide array of analytical tests including cone calorimetry, thermogravimetric analysis, and differential scanning calorimetry to better understand the physical and chemical properties of the materials.
title: Development of a tissue engineered implantable device for the surgical repair of the peripheral nervous system
Creators: name: Georgiou, Melanie
Publisher: name: The Open University
Year: 2013

description: Peripheral nerve injury as a result of trauma affects approximately 1 million people in Europe and America annually. The current clinical gold standard treatment for repairing long gaps is the nerve autograft, in which only ~50% of cases result in satisfactory functional recovery. Tissue-engineered cellular bridging devices for surgical implantation into peripheral nerve injury sites could provide an attractive alternative to the autograft. This project reports the development of a robust, anisotropic biomaterial with highly aligned cells that can form the basis of a peripheral nerve repair device.

Engineered neural tissue (EngNT), which is formed from columns of Schwann cells or stem cells within a 3D aligned collagen matrix, can promote directed neurite outgrowth in vitro. This study demonstrates that sheets of EngNT can be arranged to form the 'endoneurium' of a peripheral nerve repair device within a NeuraWrap™ outer tube, and can be used for the repair of critical sized defects in rat.

Schwann cells are the preferred cell type for peripheral nerve repair because of their ability to enhance axon migration and secrete factors that further increase regeneration. However the use of autologous Schwann cells has a number of disadvantages, including the sacrifice of host nerve tissue for their extraction and slow expansion times in vitro. Various therapeutic cell types and a bovine collagen source that can potentially be used to make EngNT to form the device core were investigated. EngNT devices containing Schwann cell-like cells from adipose-derived stem cells (dADSC) or human neural progenitor cells differentiated to glial cells (dCX) were tested in a critical sized gap in the rat sciatic nerve model. The in vivo experiments demonstrated that there is potential, for the dADSCs to be used for peripheral nerve repair. The results from the dCX repairs were less clear.

The technology reported here offers a simple, rapid and effective method for the manufacture of an aligned cellular biomaterial, and could be applied to a range of tissue engineering applications. This study demonstrates that there is potential for EngNT to be used in the construction of nerve repair conduits.
Transfer Matrices for the Zero-Temperature Potts Antiferromagnet on Cyclic and Mobius Lattice Strips

description: We present transfer matrices for the zero-temperature partition function of the $q$-state Potts antiferromagnet (equivalently, the chromatic polynomial) on cyclic and Möbius strips of the square, triangular, and honeycomb lattices of width $L_y$ and arbitrarily great length $L_x$. We relate these results to our earlier exact solutions for square-lattice strips with $L_y=3,4,5$, triangular-lattice strips with $L_y=2,3,4$, and honeycomb-lattice strips with $L_y=2,3$ and periodic or twisted periodic boundary conditions. We give a general expression for the chromatic polynomial of a Möbius strip of a lattice $Λ$ and exact results for a subset of honeycomb-lattice transfer matrices, both of which are valid for arbitrary strip width $L_y$. New results are presented for the $L_y=5$ strip of the triangular lattice and the $L_y=4$ and $L_y=5$ strips of the honeycomb lattice. Using these results and taking the infinite-length limit $L_x \to \infty$, we determine the continuous accumulation locus of the zeros of the above partition function in the complex $q$ plane, including the maximal real point of nonanalyticity of the degeneracy per site, $W$ as a function of $q$.

description: Many of the most deeply and persistently distressed regions of the U.S., such as parts of West Virginia, suffer from extremely low levels of labor force participation. These are regions where economic despair seems to have taken hold for generations and which face numerous other impediments to economic prosperity, such as opioid abuse. Better understanding these linkages can lead to policy solutions to help the most disadvantaged places break the cycle of economic despair. Using county-level data, we begin by estimating a series of models that allow us to understand the drivers of local labor force participation. We also consider how these drivers may differ between rural and urban areas. We then analyze how levels of participation in the labor force are related to other measures of economic distress. We find that there is significant variation in the drivers of rural and urban labor force participation; however, much of the variation can be explained by known factors. Yet, our results also suggest that there remains some portion of the lower levels of labor force participation in West Virginia and Appalachia that cannot be explained by other factors. Since it appears that labor force participation is important to explaining higher levels of employment growth in rural areas, for persistently distressed regions, finding ways to increase labor force participation may be a critical step toward increasing economic prosperity.

description: To successfully develop and manufacture stable biologic therapeutics and vaccines, it is paramount to understand the effects of pH and ionic strength on the intra and intermolecular biophysical properties of the protein solution. This work investigates the effects of pH and ionic strength on the biophysical properties of the broadly neutralizing HIV antibody, N6LS, which was recently discovered by the National Institutes of Health. The secondary and tertiary structure were determined by circular dichroism and intrinsic fluorescence spectroscopy and were found to be independent of solution pH and ionic strength. The conformational stability was quantified by differential scanning calorimetry; both solution parameters had pronounced effect on antibody thermal unfolding transitions and enthalpy of unfolding. To quantify protein-protein interactions and colloidal properties of the antibody solution, the diffusion interaction parameter and osmotic second virial coefficient were determined by dynamic light scattering and static light scattering and found to be dependent on pH and ionic strength. Additionally, antibody solution viscosity was measured and used to determine the intrinsic viscosity and Huggins coefficient. Intrinsic viscosity and Huggins coefficient data derived from viscosity experiments showed that N6LS antibody molecules have anisotropic conformation and behaved more like flexible polymer chains than hard spheres at pH ≥ 5.0. This work can help inform future protein biophysical and theoretical models for antibody solutions, as well as inform formulation solution conditions in manufacturing and development of future biologic therapeutics and vaccines.

description: A number of government programs, including USDA conservation programs, provide financial incentives to entice changes in behavior. An important question for these programs is whether temporary payments can lead to persistent behavioral changes. Over the past 20 years, the USDA Environmental Quality Incentives Program (EQIP) has provided more than $250 million to farmers adopting no-till crop production. In contrast to conventional tillage, which turns over the soil prior to planting, no-till can produce a number of environmental goods such as soil carbon sequestration, especially if farmers adopt no-till continuously for a long time period. This study examines whether temporary no-till payments result in persistent adoption of no-till beyond the term of conservation contracts. In the first part of our analysis, we examine field-level survey data, model no-till adoption as a second-order Markov process, and establish that in general there is considerable persistence in farmers’ tillage decisions. In the second part of our analysis, we examine a unique dataset of satellite-based estimates of field-level residue estimates in the Northern High Plains and examine changes in residue before, during, and after enrollment in EQIP. We conclude by discussing the potential implications of persistence for program outcomes as well as the challenges in identifying the mechanisms driving persistence.

description: We review recent progress in the study of the vertex-cover problem (VC). VC belongs to the class of NP-complete graph theoretical problems, which plays a central role in theoretical computer science. On ensembles of random graphs, VC exhibits an coverable-uncoverable phase transition. Very close to this transition, depending on the solution algorithm, easy-hard transitions in the typical running time of the algorithms occur. We explain a statistical mechanics approach, which works by mapping VC to a hard-core lattice gas, and then applying techniques like the replica trick or the cavity approach. Using these methods, the phase diagram of VC could be obtained exactly for connectivities $ce$, the solution of VC exhibits full replica symmetry breaking. The statistical mechanics approach can also be used to study analytically the typical running time of simple complete and incomplete algorithms for VC. Finally, we describe recent results for VC when studied on other ensembles of finite- and infinite-dimensional graphs.

description: The temporal evolution of Kuramoto oscillators influenced by the temperature field often appears in biological oscillator ensembles. In this paper, we propose a generalized Kuramoto type lattice model on a regular ring lattice with the equal spacing assuming that each oscillator has an internal energy (temperature). Our lattice model is derived from the thermodynamical Cucker-Smale model for flocking on the 2D free space under the assumption that the ratio between velocity field and temperature field at each lattice point has a uniform magnitude over lattice points. The proposed model satisfies an entropy principle and exhibits emergent dynamics under some sufficient frameworks formulated in terms of initial data and system parameters. Moreover, the phase-field tends to the Kuramoto phase-field asymptotically.

description: As part of our contribution to “The Sustainability of the UBC Food System Collaborative Project”, we have collectively examined our value assumptions to formulate a vision and define the meaning of sustainability in terms of the UBC food system. In addition to adapting the models of last year, to better conceptualize our vision, our group developed a Sustain-OThermometer. This model is used to measure the indicators we developed for the social, ecological, and economic aspects of sustainability, and can be used to assess the current situation at UBC, and more specifically our scenario: Agora. For each indicator we developed methods or instruments for data collection. We, as a group, examined the current state of Agora, and focused on 3 specific tasks: 1) assess the operation requirements and limitations resulting from regulatory legislation, logistical restrictions and human resource and labor relations issues; 2) propose a plan for forms of collaboration and possible contractual arrangements with local producers and suppliers, including UBC Farm and UBC Natural Food Co-op; and 3) assess the feasibility and desirability of a business/mentor relationship between the new Agora and UBC food services. Upon doing so, we have explored solutions for Agora in reference to the three components: social, ecological and economic. Lastly, these we proposed recommendations to the various stakeholders involved with Agora so as to initiate a transition towards realistic sustainability.

description: We analyze how agricultural extension can be made more effective in terms of increasing smallholder farmers’ adoption of pro-nutrition technologies, such as biofortified crops. In a randomized controlled trial with farmers in Western Kenya, we implemented several extension treatments and evaluated their effects on the adoption of beans that were biofortified with iron and zinc. Difference-in-difference estimates show that intensive agricultural training tailored to local conditions can increase technology adoption considerably. Within less than one year, adoption of biofortified beans increased from almost zero to more than 20%. Providing additional nutrition training further increased adoption by another 10-12 percentage points, as this has helped farmers to better appreciate the technology’s nutritional benefits. These results suggest that effective nutrition training through agricultural extension services is possible. Providing marketing training did not lead to additional adoption effects, although the study period may have been too short to measure these effects properly. This study is a first attempt to analyze how improved designs of agricultural extension can help to make smallholder farming more nutrition-sensitive. More research in this direction is needed.

description: This paper focuses on personal and possessive pronouns in English and Erei (a micro-minority language spoken by the Erei people in Biase Local Government Area of Cross River State, Nigeria). It seeks to determine the nature, similarities and differences in the pronouns of both languages using Universal Grammar as the linguistic approach. Data used for the study were extracted from stories told by six Erei native speakers and secondary materials. The findings reveal that both languages have a set of fundamental principles which are the properties of all languages. Elowever, there are variations in terms of parameters that set the choice of entry(ies) in each of the languages. Although both languages have the three grammatical persons and possessive pronouns that are referents to one‟s parts of the body and personal belongings, there are striking differences in variants, number of slots per lexical entry and the position of the pronoun elements within the clause. The study has shown that English and Erei have certain principles in common. This study aims to trigger off further researches on the grammar of Erei language with the aim of developing the needed materials in order to revitalize and modify the language for pedagogic purposes

description: We formulate and study a new coarse (co-)assembly map. It involves a modification of the Higson corona construction and produces a map dual in an appropriate sense to the standard coarse assembly map. The new assembly map is shown to be an isomorphism in many cases. For the underlying metric space of a group, the coarse co-assembly map is closely related to the existence of a dual Dirac morphism and thus to the Dirac dual Dirac method of attacking the Novikov conjecture.

LORENZO LOTTO’S PORTRAITS OF WOMEN: A CASE STUDY OF INNOVATIONS IN CINQUECENTO FEMALE PORTRAITURE
Creators: name: Chadbourne, Amanda
Publisher: name: American University
Year: 2023

description: This thesis argues that the Cinquecento Venetian artist Lorenzo Lotto, inspired by the innovations in female portraiture of Leonardo da Vinci and Giorgione, sought to imbue single-sitter portraits of women with a higher level of individualism and personality, resulting in a sense of agency and autonomy not typical of other portraits of women in the period. Through a case study of Lotto’s Portrait of a Lady as Lucretia, with additional analysis of his Lucina Brembati and Laura da Pola portraits, I explore the ambiguity tied to gender and sexuality often present after the rise of new categories of female portraits, especially the new genre depicting mistresses and courtesans in sixteenth century Italy. Further, I propose an alternative identity for the sitter in the Lucretia portrait than the conventional one, which identifies her as a noblewoman named Lucrezia Pesaro. I argue rather that she is a cortigiana onesta, or honest courtesan, who adopted the pseudonym Lucrezia (the vernacular version of Lucretia) in order to convey humanistic learning and ironic wit concerning the theme of chastity in relation to her profession. Courtesans occupied an ambiguous place in Renaissance society; this could at times threaten to upset conventional gender roles in society. Part of my argument is that the artistic traditions of Venice and Northern Italy, along with the unique culture of courtesans in Venice, spurred Lotto’s ingenuity in crafting an ambivalent and multi-dimensional portrait that showcased his sitter’s identity in a novel way. I will also argue that this ambiguity was not limited to portraits of courtesans, and with the additional interpretive layers of various paragone, extended to other portraits of women. This thesis asserts that Lotto should be considered among the most innovative artists of the sixteenth century in the genre of female portraiture.

description: We present our results on properties of ground states for nucleonic systems in the presence of random two-body interactions. In particular we present probability distributions for parity, seniority, spectroscopic (i.e., in the laboratory framework) quadrupole moments and $α$ clustering in the ground states. We find that the probability distribution for the parity of the ground states obtained by a two-body random ensemble simulates that of realistic nuclei: positive parity is dominant in the ground states of even-even nuclei while for odd-odd nuclei and odd-mass nuclei we obtain with almost equal probability ground states with positive and negative parity. In addition we find that for the ground states, assuming pure random interactions, low seniority is not favored, no dominance of positive values of spectroscopic quadrupole deformation, and no sign of $α$-cluster correlations, all in sharp contrast to realistic nuclei. Considering a mixture of a random and a realistic interaction, we observe a second order phase transition for the $α$-cluster correlation probability.

I argue rather that she is a cortigiana onesta, or honest courtesan, who adopted the pseudonym Lucrezia (the vernacular version of Lucretia) in order to convey humanistic learning and ironic wit concerning the theme of chastity in relation to her profession. Courtesans occupied an ambiguous place in Renaissance society; this could at times threaten to upset conventional gender roles in society. Part of my argument is that the artistic traditions of Venice and Northern Italy, along with the unique culture of courtesans in Venice, spurred Lotto’s ingenuity in crafting an ambivalent and multi-dimensional portrait that showcased his sitter’s identity in a novel way. I will also argue that this ambiguity was not limited to portraits of courtesans, and with the additional interpretive layers of various paragone, extended to other portraits of women. This thesis asserts that Lotto should be considered among the most innovative artists of the sixteenth century in the genre of female portraiture.
Shot noise in normal metal-d-wave superconducting junctions

description: We present theoretical calculations and predictions for the shot noise in voltage biased junctions of $d_{x^2-y^2}$ superconductors and normal metal counter-electrodes. In the clean limit for the d-wave superconductor the shot noise vanishes at zero voltage because of resonant Andreev reflection by zero-energy surface bound states. We examine the sensitivity of this resonance to impurity scattering. We report theoretical results for the magnetic field dependence of the shot noise, as well the fingerprints of subdominant $s$- and $d_{xy}$ pairing channels.

title: Making memory work: Performing and inscribing HIV/AIDS in post-apartheid South Africa
Creators: name: Doubt, Jenny Suzanne
Publisher: name: The Open University
Year: 2014

description: This thesis argues that the cultural practices and productions associated with HIV/AIDS represent a major resource in the struggle to understand and combat the epidemic. Research into HIV/AIDS is dominated by biomedical scholarship, and yet in South Africa, the main drivers of the epidemic are social and economic. The cultural productions analysed in this thesis confront and illuminate many of the contradictory and unresolved questions facing HIV/AIDS research today. The primary materials analysed in this thesis are the cultural texts that explore representations and performances of HIV/AIDS in South Africa from 1995-2012. I locate experiences of HIV/AIDS in a range of theatrical, literary and visual artworks, including prose, drama and memoir, as well as film and critical work across an array of genres. More than simply surveying HIV/AIDS cultural artefacts, I offer socially and historically contextualised accounts of how stories from post-apartheid writers, performers, artists and subjects engage with HIV/AIDS within a climate hostile to their existence. In my analysis of the texts considered, I develop an argument that underlines the interventionist capacities of cultural production around HIV/AIDS. I investigate to what degree these texts aim to change consciousness and challenge the social behaviours that contribute to HIV prevalence. I argue that the most significant responses to HIV/AIDS in the last thirty years have been grassroots cultural practices that empower those who otherwise have had little agency in dictating their own circumstances and histories of the epidemic. These findings lead me to argue for a paradigm shift in HIV/AIDS research: from the widespread application of medical hegemony to the consideration of community-level cultural interventions in addressing the epidemic.

Promoting Racial Equity in Ballet: Strategies and Challenges
Creators: name: Ogden, Stephanie
Publisher: name: ProQuest
Year: 2023
Subjects: classificationCode: 3604
subject: Performing arts

description: Ballet is a world of exquisite artistry and strong tradition that has evolved beyond its origins as an elite court dance of 17th century France into a global art form reaching audiences throughout the world. Yet, to this day, ballet remains mostly white. This inequity is found not only on the stage, but in the ballet school, executive suite, and boardroom. Racial inequity in ballet is born of a complex system of historical, social, and organizational issues, including: artistic tradition, racism, socioeconomics, cultural policy, education, funding, management, and governance. Because these issues are not independent but intersectional, they must be examined and addressed holistically. By conducting surveys, interviews, and a thorough literature review, the author dissects the challenges ballet companies face in promoting racial equity and identifies strategies being implemented to address those challenges. The author posits that racial equity must come from the top of an organization, with leaders setting policy that leads actionable change. Simultaneously, there must be a bottom-up approach where access, education, and opportunity are given to rising dancers and leaders of color. This paper is meant to be a working resource for all dance professionals seeking to promote racial equity in ballet.

description: In this article the focus is on the structural changes that have occurred recently in South Africa in respect of ownership and the right of use of land in commercial agricultural production units. Attention is devoted more specifically to changes in respect of the numbe~ of farmers and farms, farm sizes, types of ~nterpnse, the lease of land and part-time farm1?g. ~n effort was made to answer the following questions m respect of every structural component: - What changes have recently occurred? What were the most important socio-economic forces behind these changes? What socio-economic forces should have an important influence on these changes in the near future? What are the effects of these changes on their structural components likely to be? Is the direction which the changes are expected to take desirable from the point of view of social welfare? Briefly, the ~nding was that important changes, caused by a vanety of factors, are taking place in respect of every structural component and that the direction which these structural changes are taking is not very desirable from the point of view of social welfare. Possible courses of action to deal with this problem are discussed.
Classification of states of single-$j$ fermions with $J$-pairing interaction

description: In this paper we show that a system of three fermions is exactly solvable for the case of a single-$j$ in the presence of an angular momentum-$J$ pairing interaction. On the basis of the solutions for this system, we obtain new sum rules for six-$j$ symbols. It is also found that the "non-integer" eigenvalues of three fermions with angular momentum $I$ around the maximum appear as "non-integer" eigenvalues of four fermions when $I$ is around (or larger than) $J_{\rm max}$ and the Hamiltonian contains only an interaction between pairs of fermions coupled to spin $J=J_{\rm max}=2j-1$. This pattern is also found in five and six fermion systems. A boson system with spin $l$ exhibits a similar pattern.

Overcharging magnetized black holes at linear order and the weak cosmic censorship conjecture

description: Evidences have been found that the weak cosmic censorship conjecture could be violated if test particles with charge and angular momentum are injected into a black hole. However, second-order corrections and fine-tunings on the particle's parameters are required in previous studies, indicating that self-force and radiative effects must be taken into account. In this paper, we first consider a magnetically charged particle falling into an extremal Bardeen black hole, which is regular (with no singularity) and has a magnetic monopole at the center. We then investigate a general class of magnetic black holes with or without singularities. In all the cases, we show that the test particle with magnetic charge could overcharge the black hole, causing possible violation of the weak cosmic censorship conjecture. In contrast to previous arguments in the literature, second-order corrections are not necessary in our analysis and the results are not sensitive to the particle's parameters. Our work indicates that the self-force effect, which is related to the second-order correction, may not help rescue the weak cosmic censorship conjecture in our examples.
