description: In this paper, we have considered the interplay between phase transitions and configuration mixing of intruder excitations in the 118-128Te isotopes. A transitional interacting boson model Hamiltonian in both IBM-1 and IBM-2 versions which are based on affine Lie Algebra are employed to describe the evolution from spherical to deformed gamma unstable shapes along the chain of Te isotopes. The excitation energies, B(E0) and B(E2) transition rates are rather well reproduced in comparison with experimental counterparts when the weight of SO(6) limit is increased in Hamiltonian. Also our results show obvious relations between the configuration mixing ratio and quadrupole, hexadecapole and hexacontatetrapole deformation values in this isotopic chain.

description: Wavefront shaping has revolutionized imaging deep in scattering media, being able to spatially and temporally refocus light through or inside the medium. However, wavefront shaping is not compatible yet with polarization-resolved microscopy given the need of polarizing optics to refocus light with a controlled polarization state. Here, we show that wavefront shaping is not only able to restore a focus, but it can also recover the injected polarization state without using any polarizing optics at the detection. This counter-intuitive effect occurs up to several transport mean free path thick samples, which exhibit a speckle with a completely scrambled state. Remarkably, an arbitrary rotation of the input polarization does not degrade the quality of the focus. This unsupervised re-polarization - out of the originally scrambled polarization state - paves the way for polarization-resolved structural microscopy at unprecedented depths. We exploit this phenomenon and demonstrate second harmonic generation (SHG) structural imaging of collagen fibers in tendon tissues behind a scattering medium.

description: Virtual Machines (VMs) with Just-In-Time (JIT) compilers are traditionally thought to execute programs in two phases: the initial warmup phase determines which parts of a program would most benefit from dynamic compilation, before JIT compiling those parts into machine code; subsequently the program is said to be at a steady state of peak performance. Measurement methodologies almost always discard data collected during the warmup phase such that reported measurements focus entirely on peak performance. We introduce a fully automated statistical approach, based on changepoint analysis, which allows us to determine if a program has reached a steady state and, if so, whether that represents peak performance or not. Using this, we show that even when run in the most controlled of circumstances, small, deterministic, widely studied microbenchmarks often fail to reach a steady state of peak performance on a variety of common VMs. Repeating our experiment on 3 different machines, we found that at most 43.5% of pairs consistently reach a steady state of peak performance.

Year: 2017

description: Vital pulp therapy (VPT) remains a treatment option for cariously exposed teeth that reach the dental pulp. To our knowledge no study has examined whether perioperative pain predicts the outcome of VPT. The aim of this study is to examine the between perioperative pain and the progression of pulpal disease into a more inflamed or necrotic state. Direct pulp caps or partial pulpotomies using MTA were performed on permanent teeth with carious pulpal exposures. Patients were contacted at 24 hours, one week and three months following treatment and data was collected on pain experienced and analgesic intake using a standardized questionnaire. At six and 12 months after treatment an in-person clinical exam was performed on each subject which included standard vitality tests along with exposure of a periapical radiograph. Success was defined as an asymptomatic, functional tooth that does not present with any clinical or radiographic pathology and has not had previous root canal treatment. Statistical analysis was performed using logistic regression. Results from this study support a correlation between perioperative pain at 3 months and the outcome of VPT.

description: A new type of anomalous Hall effect is shown to arise from the interaction of conduction electrons with dipolar spin waves in ferromagnets. This effect exists even in homogeneous ferromagnets without relativistic spin-orbit coupling. The leading contribution to the Hall conductivity is proportional to the chiral spin correlation of dynamical spin textures and is physically understood in terms of the skew scattering by dipolar magnons.

description: Candida auris is an emerging worldwide concern, but comparative data about the virulence of different C. auris lineages in mammalian hosts is lacking. Different isolates of the four prevalent C. auris clades (South Asian n = 5, East Asian n = 4, South African n = 5, and South American n = 5) were compared to assess their virulence in a neutropenic murine bloodstream infection model with C. albicans as reference. C. auris, regardless of clade, proved to be less virulent than C. albicans. Highest overall mortality at day 21 was observed for the South American clade (96%), followed by the South Asian (80%), South African (45%) and East Asian (44%) clades. Fungal burden results showed close correlation with lethality. Histopathological examination revealed large aggregates of blastoconidia and budding yeast cells in the hearts, kidneys and livers but not in the spleens. The myocardium of apparently healthy sacrificed mice as well as of mice found moribund showed contraction band necrosis in case of all lineages. Regardless of clade, the heart and kidneys were the most heavily affected organs. Isolates of the same clade showed differences in virulence in mice, but a markedly higher virulence of the South American clade was clearly demonstrated.
I have walked the earth a proud soldier and... ceased to do so: North Carolina Confederates confront defeat, 1864-1868

Year: 2009

description: As wartime defeat thwarted their ambitions for independence, former Confederates in North Carolina attempted to reconstruct their domestic worlds along antebellum lines while constructing new modes of racial interaction in the wake of the destruction of slavery. Analyzing Confederates' reflections on defeat as a product of their age reveals that younger men met displayed stout ideological resistance, while their elders considered pragmatic solutions to reorder their world. Men younger than thirty expressed continued attachment to Confederate nationalism, strong emotions when writing about African-Americans and their fate, and a commitment to uphold fixed notions of gendered social and domestic roles in their wartime and immediate postwar writings. Men older than thirty, though holding similar convictions to their juniors, conceived of nationalism in terms of sacrifice, race as a temporary obstacle to social and economic tranquility under the guise of white supremacy, and gender as a set of mutating obligations and challenges.

description: We exploit offshell regions in the process $e^+e^-\rightarrow W^+W^-b\bar{b}$ to gain access to the top-quark width. Working at next-to-leading order in QCD we show that carefully selected ratios of offshell regions to onshell regions in the reconstructed top and antitop invariant mass spectra are, \emph{independently} of the coupling $g_{tbW}$, sensitive to the top-quark width. We explore this approach for different centre of mass energies and initial-state beam polarisations at $e^+e^-$ colliders and briefly comment on the applicability of this method for a measurement of the top-quark width at the LHC.

description: For Brylinski-Deligne covering groups of an arbitrary split reductive group, we consider theta representations attached to certain exceptional genuine characters. The goal of the paper is to determine when a theta representation has exactly a one-dimensional space of Whittaker functionals, in which case it is called distinguished. For this purpose, we first give effective lower and upper bounds for the dimension of Whittaker functionals for general theta representations. As a consequence, the dimension in many cases can be reduced to simple combinatorial computations, e.g., the Kazhdan-Patterson covering groups, or covering groups whose complex dual group is of adjoint type. In the second part of the paper, we consider covering groups of certain simply-connected groups and give necessary and sufficient condition for the theta representation to be distinguished. There are subtleties arising from the relation between the rank and the degree of the covering group. However, in each case we will determine the exceptional character such that its associated theta representation is distinguished.

Roma in the Czech Republic and Spain: a study of the influence of the European Union on minority rights
Creators: name: Meek, Alana Therasa
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2008

description: My thesis will focus on whether and how membership conditionality has improved minority rights in the recently acceded members of the European Union (EU), and what lessons one can draw from this for existing member states. Does the Copenhagen conditionality process provide additional, and more effective means, for the EU to compel its member states to respect minority rights? I examine this question by investigating the record of minority rights for the Roma in two EU member states, one subject to the Copenhagen Criteria (Czech Republic) and one not (Spain). I find that while the Criteria have provided the Roma in the Czech Republic with more legal rights, this in practice led to limited change because persistent discrimination has impeded implementation. Hence, simply imposing the Criteria on Western members states, such as Spain, may not improve the fate of Roma much. Long-term change cannot be achieved via the implementation of laws; the change sought is attitudinal.

description: The recent Zika virus (ZIKV) epidemic in the Americas, followed by the yellow fever virus (YFV) outbreaks in Angola and Brazil highlight the urgent need for safe and efficient vaccines against the ZIKV as well as much greater production capacity for the YFV-17D vaccine. Given that the ZIKV and the YFV are largely prevalent in the same geographical areas, vaccines that would provide dual protection against both pathogens may obviously offer a significant benefit. We have recently engineered a chimeric vaccine candidate (YF-ZIKprM/E) by swapping the sequences encoding the YFV-17D surface glycoproteins prM/E by the corresponding sequences of the ZIKV. A single vaccine dose of YF-ZIKprM/E conferred complete protection against a lethal challenge with wild-type ZIKV strains. Surprisingly, this vaccine candidate also efficiently protected against lethal YFV challenge in various mouse models. We demonstrate that CD8+ but not CD4+ T cells, nor ZIKV neutralizing antibodies are required to confer protection against YFV. The chimeric YF-ZIKprM/E vaccine may thus be considered as a dual vaccine candidate efficiently protecting mice against both the ZIKV and the YFV, and this following a single dose immunization. Our finding may be particularly important in the rational design of vaccination strategies against flaviviruses, in particular in areas where YFV and ZIKV co-circulate.
On transparency: a response to Nishi Shah’s “How truth governs belief"
Creators: name: Given, Emily Adams
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2007

description: In his 2003 paper “How Truth Governs Belief” Nishi Shah claims that within first personal doxastic deliberation, one cannot separate the questions whether to believe some proposition p and whether p is true; the questions must be viewed as answered by and answerable to the same set of considerations. He calls this phenomenon transparency, and argues that the only way to explain it is by understanding the concept of belief as being normatively tied to truth. In deliberating about whether to believe we exercise our concept of belief, appreciate it’s normative connection to truth, and so incite the collapse of these two questions. By way of offering a response to Shah, I argue on behalf of teleological accounts of belief that there is a competing explanation of transparency. Despite Shah’s dilemma, it seems to me that the teleologist, making metaphysical rather than conceptual claims, can recover an explanation of why truth is normative for belief in the way transparency reveals.
Fragmentation in the phi^3 Theory and the LPHD Hypothesis

description: We present analytic solution of the Dokshitzer-Gribov-Lipatov-Altarelli-Parisi (DGLAP) equation at leading order (LO) in the phi^3 theory in 6 space-time dimensions. If the phi^3 model was the theory of strong interactions, the obtained solution would describe the distribution of partons in a jet. We point out that the local parton-hadron duality (LPHD) conjecture does not work in this hypothetical situation. That is, treatment of hadronisation of shower partons is essential for the description of hadron distributions in jets stemming from proton-proton (pp) collisions at \sqrt{s} = 7 TeV and from electron-positron (e+e-) annihilations at various collision energies. We use a statistical model for the description of hadronisation.

Transnational Smyth: Suffrage, Cosmopolitanism, Networks
Creators: name: Fedor, Erica
Publisher: name: The University of North Carolina at Chapel Hill University Libraries

description: This thesis examines the transnational entanglements of Dame Ethel Smyth (1858–1944), which are exemplified through her travel and movement, her transnational networks, and her music’s global circulation. Smyth studied music in Leipzig, Germany, as a young woman; composed an opera (The Boatswain’s Mate) while living in Egypt; and even worked as a radiologist in France during the First World War. In order to achieve performances of her work, she drew upon a carefully-cultivated transnational network of influential women—her powerful “matrons.” While I acknowledge the sexism and misogyny Smyth encountered and battled throughout her life, I also wish to broaden the scholarly conversation surrounding Smyth to touch on the ways nationalism, mobility, and cosmopolitanism contribute to, and impact, a composer’s reputations and reception. Smyth herself acknowledges the particular double-bind she faced—that of being a woman and a composer with German musical training trying to break into the English music scene. Using Ethel Smyth as a case study, this thesis draws upon the composer’s writings, reviews of Smyth’s musical works, popular-press articles, and academic sources to examine broader themes regarding the ways nationality, transnationality, and locality intersect with issues of gender and institutionalized sexism. Such intersections have the power to shape labels of insider/outsider and influence whose music gets performed, studied, and remembered.

description: Modeling variability in Matlab/Simulink becomes more and more important. We took the two variability modeling concepts already included in Matlab/Simulink and our own one and evaluated them to find out which one is suited best for modeling variability in the automotive domain. We conducted a controlled experiment with developers at Volkswagen AG to decide which concept is preferred by developers and if their preference aligns with measurable performance factors. We found out that all existing concepts are viable approaches and that the delta approach is both the preferred concept as well as the objectively most efficient one, which makes Delta-Simulink a good solution to model variability in the automotive domain.

We show a well-controlled technique to prepare entangled qudits states as well as to implement dissipative local measurements; the latter realize two specific dynamics: dephasing and amplitude damping. Our work represents a new analogy-dynamical experiment for simulating an open quantum system.

description: A code generator systematically transforms compact models to detailed code. Today, code generation is regarded as an integral part of model-driven development (MDD). Despite its relevance, the development of code generators is an inherently complex task and common methodologies and architectures are lacking. Additionally, reuse and extension of existing code generators only exist on individual parts. A systematic development and reuse based on a code generator product line is still in its infancy. Thus, the aim of this paper is to identify the mechanism necessary for a code generator product line by (a) analyzing the common product line development approach and (b) mapping those to a code generator specific infrastructure. As a first step towards realizing a code generator product line infrastructure, we present a component-based implementation approach based on ideas of variability-aware module systems and point out further research challenges.

description: The collapse of the Soviet Union left countries of Central Asia to experience political confrontations over territory and water rights. Additionally, independence of Central Asian countries resulted in the change of control systems, including transboundary rivers of the region. Resource capture, and isolation of Uzbekistan and Turkmenistan in early years of independence, from water cooperation, as well as engagements, brought to the competition over water resources. Moreover, upstream-downstream controversy and water politics in Central Asia have been intensifying at a fast pace in recent years. This paper discusses why Central Asian governments undergo conflicts over water and how those concerns can be addressed for an effective cooperation. In this regard, this paper provides analysis of the existing legal frameworks, in particular, over Amu Darya river. As a result, I argue that countries in the region need third-party participation for creating effective water management and cooperation.

We include the viscous energy generation in the mix-length convection equations in accretion disks. The optical and X-ray light curves of X-ray nova A0620-00 are investigated in terms of this model. The turbulent viscosity parameter of the accretion disk is estimated, $α= 0.5 ÷0.6$, which is necessary to explain the luminosity decay rate on the descending branch of the X-ray light curve for the A0620-00 1975 outburst. The secondary luminosity maximum on the light curves is explained by assuming an additional injection of matter into the accretion disk from the optical companion.

Four-body CDCC well reproduces the experimental data with no adjustable parameter for 6Li + 209Bi scattering at Ein = 24-50 MeV and 6Li + 208Pb scattering at Ein = 29-210 MeV. In the wide Ein range, 6Li breakup is significant and provides repulsive corrections to the folding potential. As an interesting property, d breakup is strongly suppressed in 6Li-breakup processes independently of Ein. We investigate what causes the d-breakup suppression.

Fake forensics, real effects?: testing the cultivating power of crime drama

Year: 2011

description: Central to cultivation theory is the premise that television's recurrent narrative, visual, and ideological patterns cultivate viewers' (mis)constructions of the real world in a manner positively correlated with the amount and types of exposure. This study tested that premise by examining the relationships between and among crime drama viewing, perceptions of the effectiveness of the U.S. criminal justice system, and scientific literacy via an analytical web-based survey of 1,365 undergraduate students. Contrary to the cultivation thesis, few significant and no strong associations emerged between or among any of the study's main variables; in other words, little evidence of cultivation effects or processes was manifest in the data.

description: In model-driven development (MDD) software emerges by systematically transforming abstract models to concrete source code. Ideally, performing those transformations is to a large extent the task of code generators. One approach for developing a new code generator is to write a reference implementation and separate it into handwritten and generatable code. Typically, the generator developer manually performs this separation a process that is often time-consuming, labor-intensive, difficult to maintain and may produce more code than necessary. Software categories provide a way for separating code into designated parts with defined dependencies, for example, "Business Logic" code that may not directly use "Technical" code. This paper presents an approach that uses the concept of software categories to semi-automatically determine candidates for generated code. The main idea is to iteratively derive the categories for uncategorized code from the dependencies of categorized code. The candidates for generated or handwritten code finally are code parts belonging to specific (previously defined) categories. This approach helps the generator developer in finding candidates for generated code more easily and systematically than searching by hand and is a step towards tool-supported development of generative software.

Tearing and Surface Preserving Electron Magnetohydrodynamic Modes in A Current Layer

description: In this paper, we have carried out linear and nonlinear analysis of tearing and surface preserving modes of two dimensional (2D) Electron Magnetohydrodynamics (EMHD). A linear analysis shows that the perturbations parallel to equilibrium magnetic field $B_0$ (characteristic tangent hyperbolic spatial profile), driven by the current gradients, lead to two different modes. The first mode is the tearing mode having a non-local behavior which requires the null-line in the magnetic field profile. Whereas, the second mode is a surface preserving local mode which does not require the null-line in the magnetic field. The quantity $B_0 - B_0^{''}$ should change sign for these modes to exist. In nonlinear simulations, for tearing case we observe formation of magnetic island at the null-line due to the reconnection of magnetic field lines. However, for surface preserving mode, a channel like structure is observed instead of the island structure.

description: We show that the theta representations on certain covers of general linear groups support certain types of unique functionals. The proof involves two types of Fourier coefficients. The first are semi-Whittaker coefficients, which generalize coefficients introduced by Bump and Ginzburg for the double cover. The covers for which these coefficients vanish identically (resp. do not vanish for some choice of data) are determined in full. The second are the Fourier coefficients associated with general unipotent orbits. In particular, we determine the unipotent orbit attached, in the sense of Ginzburg, to the theta representations.

description: van der Waals (vdW) heterojunctions formed by two-dimensional (2D) materials have attracted tremendous attention due to their excellent electrical/optical properties and device applications. However, current 2D heterojunctions are largely limited to atomic crystals, and hybrid organic/inorganic structures are rarely explored. Here, we fabricate hybrid 2D heterostructures with p-type dioctylbenzothienobenzothiophene (C8-BTBT) and n-type MoS2. We find that few-layer C8-BTBT molecular crystals can be grown on monolayer MoS2 by vdW epitaxy, with pristine interface and controllable thickness down to monolayer. The operation of the C8-BTBT/MoS2 vertical heterojunction devices is highly tunable by bias and gate voltages between three different regimes: interfacial recombination, tunneling and blocking. The pn junction shows diode-like behavior with rectifying ratio up to 105 at the room temperature. Our devices also exhibit photovoltaic responses with power conversion efficiency of 0.31% and photoresponsivity of 22mA/W. With wide material combinations, such hybrid 2D structures will offer possibilities for opto-electronic devices that are not possible from individual constituents.

description: This course-based primer provides newcomers to the field with a concise introduction to some of the core topics in the emerging field of topological band insulators in one and two dimensions. The aim is to provide a basic understanding of edge states, bulk topological invariants, and of the bulk--boundary correspondence with as simple mathematical tools as possible. We use noninteracting lattice models of topological insulators, building gradually on these to arrive from the simplest one-dimensional case (the Su-Schrieffer-Heeger model for polyacetylene) to two-dimensional time-reversal invariant topological insulators (the Bernevig-Hughes-Zhang model for HgTe). In each case the model is introduced first and then its properties are discussed and subsequently generalized. The only prerequisite for the reader is a working knowledge in quantum mechanics, the relevant solid state physics background is provided as part of this self-contained text, which is complemented by end-of-chapter problems.

A Sea Change for the Transatlantic Security Regime? Maritime Security Cooperation, Coordination, and Competition in the Horn of Africa Region

description: The end of Cold War-era bipolarity and the rise of global multipolarity have been particularly consequential for the transatlantic security regime. This regime has seen the North Atlantic Treaty Organization's expansion into out-of-area operations and the emergence of the European Union as a security actor in its own right. Yet consistent formal cooperation between those two actors has proven difficult, and the United States of America has increasingly sought to achieve its security objectives through alternative multinational fora--seemingly reconsidering the mantle of its historical hegemony within the regime. By exploring recent interactions between these three actors at the political level and through the lens of their overlapping counter-piracy operations in the Horn of Africa region, this thesis seeks to establish whether such concurrent missions indicate increased security competition between historical allies, or rather, the advent of more flexible modalities in transatlantic security cooperation.
The correlation between time loss due to injury and perceived health status in female collegiate dance students

description: Dancers are a unique blend of artist and athlete particularly susceptible to musculoskeletal injuries and pain. When treating any athlete, it is important to consider the personal perception of health status. When considering the dancer, however, these perceptions may be especially important. One of the most widely used measures of perceived health status is the Short Form-36 (SF-36) Health Survey. Seventy-seven college dance students (aged 18-24) completed a survey containing the SF-36, in addition to an injury history and various dance specific questions. The goal of this study was to determine the correlation between total time loss due to injury (in days) and perceived health status in collegiate dance students. No significant correlation was found when examining time loss due to injury to the Physical (N = 73, r = -.096, p = .421) and Mental (N = 72, r = .006, p = .958) SF-36 scales. However, the relationship between sex-matched mental health status normative values and our measured values were statistically significant (t = -2.033, df = 71, p = .046). The results from our study suggest that the SF-36 health survey may represent an accurate way to measure mental health status if administered during a pre-season injury screen creating a baseline value for individual dancers. Progress could then be observed in an objective way previously difficult to measure among this population, specifically, the progress pertaining to the mental aspect of injury rehabilitation.
On Capacity Formulation with Stationary Inputs and Application to a Bit-Patterned Media Recording Channel Model

description: In this correspondence, we illustrate among other things the use of the stationarity property of the set of capacity-achieving inputs in capacity calculations. In particular, as a case study, we consider a bit-patterned media recording channel model and formulate new lower and upper bounds on its capacity that yield improvements over existing results. Inspired by the observation that the new bounds are tight at low noise levels, we also characterize the capacity of this model as a series expansion in the low-noise regime. The key to these results is the realization of stationarity in the supremizing input set in the capacity formula. While the property is prevalent in capacity formulations in the ergodic-theoretic literature, we show that this realization is possible in the Shannon-theoretic framework where a channel is defined as a sequence of finite-dimensional conditional probabilities, by defining a new class of consistent stationary and ergodic channels.

description: Since 2013, highly pathogenic avian influenza (HPAI) subtype H5N6 (clade 2.3.4.4) has been reported in wild birds and poultry in Asia as well as in other parts of the globe. In Africa, information on the presence of this virus subtype is lacking. This study reports the first detection of a HPAI (H5N6) virus (clade 2.3.4.4b) in a duck from a live bird market in Nigeria, whose genome is closely related to the European 2017–2018 H5N6 viruses, indricating a recent virus introduction into the African continent.
A la recherche du sens perdu. Überlegungen zur Rekonstruktion von Bedeutungsdimensionen volkskundlich-kulturwissenschaftlicher Universitätssammlungen

description: Am Beispiel der Sachkultursammlung des Tübinger Ludwig-Uhland-Instituts für Empirische Kulturwissenschaft fragt der Beitrag danach, wie sich einstige Bedeutungsdimensionen volkskundlich-kulturwissenschaftlicher Universitätssammlungen methodisch rekonstruieren lassen. Ausgangspunkt ist die Feststellung, dass die volkskundlich-kulturwissenschaftlichen Sammlungen als „Lehrsammlungen“ deklariert wurden und werden, obgleich erste Forschungen die Vermutung nahe legen, dass die Sammlungen in der Vergangenheit nur bedingt für die Lehre von Bedeutung waren. Als Basis zur Rekonstruktion möglicher anderer Bedeutungsdimensionen plädiert die Autorin dafür, ein ‚Collectiogramm‘ anhand überlieferter Sammlungsinventare anzufertigen. Der damit sichtbar gemachte ‚Puls der Sammlung‘ gibt mit den darin veranschaulichten Phasen erhöhter Sammlungsaktivität die grobe Richtung der weiteren Forschung vor. Er lenkt in und durch die zu konsultierenden Archive. Die Archive können als zentrales Medium zur Entschlüsselung des Sinngehalts der Sammlung zu unterschiedlichen Zeiten gelten. In Anlehnung an die in der Europäischen Ethnologie diskutierte Methode der Immersion spricht sich die Autorin dafür aus, gerade die Anfangsphase der (Archiv-)Forschung möglichst offen zu halten und sich konsequent vom vorgefundenen Material leiten zu lassen. Die so ermöglichten Zufallsfunde sind wichtig, um das Forschungsfeld in seiner Komplexität und seinen vielfältigen Bezügen zu verstehen. Das wird ansatzweise am Beispiel der Tübinger Sachkultursammlung in den 1960er Jahren demonstriert.
A Threshold of Flowers: Public and Private Eroticism in the Poems of Leona Florentino

description: Leona Florentino (1849-1884) is a foundational poet and dramatist from the port city of Vigan, located on the northern Philippine island of Luzón, then part of the Spanish Empire. Florentino’s literary production blurs and challenges established gender boundaries and regulations. Writing from the doubly marginalized perspective of a woman and of a colonial subject, Florentino utilizes the imagery of the garden to mobilize a verdant critique against the established gender roles, structures of desire, and domestic and public spaces. Many of Florentino’s known poems were written for public celebrations. However, the private poems she composed conjure erotic themes in a more conspicuous fashion. This study analyzes the ways in which Florentino utilizes garden imagery in two celebratory poems and one erotic composition to harness the tensions between the public and private spheres, and illuminates her representations of gender roles and female sexuality in nineteenth century Vigan.

description: Anthropogenic environmental changes are occurring globally and are having dramatic effects on wildlife. Successful urban animals can alter behaviours to adjust to these conditions, but it is not well understood how these modifications arise. In particular, exploratory personality and behavioural plasticity are predicted to facilitate colonization in urban areas. The link between exploratory personality, cognition, and plasticity has received little attention, and has never been examined in urban animals. The first objective of this thesis was to examine the relationship between exploratory personality and habituation in a novel environment, and determine whether variation at the individual-level is predicted by urbanization. The second objective was to explore the association between exploratory personality and spatial cognition within scatter hoarders, and assess spatial memory along an urban gradient. At the individual-level, I report significant inter-individual differences in exploratory personality and habituation. I found evidence that fast initial explorers tend to habituate in a novel environment over time while slow explorers do not. There was no significant relationship between exploratory personality and spatial cognition within individuals. At the population level, urbanization did not significantly predict habituation or spatial cognition. I do report a significant positive relationship between urbanization and exploration. Overall, I conclude that urban individuals are significantly faster explorers, but are not more behaviourally plastic and do not show differences in spatial memory. Further work examining personality, cognition, and plasticity within individuals is needed to determine whether these traits have implications for populations under different environmental conditions.
Killing Forms, W-Invariants, and the Tensor Product Map

Linear Algebraic Group

description: Associated to a split, semisimple linear algebraic group G is a group of invariant quadratic forms, which we denote Q(G). Namely, Q(G) is the group of quadratic forms in characters of a maximal torus which are fixed with respect to the action of the Weyl group of G. We compute Q(G) for various examples of products of the special linear, special orthogonal, and symplectic groups as well as for quotients of those examples by central subgroups. Homomorphisms between these linear algebraic groups induce homomorphisms between their groups of invariant quadratic forms. Since the linear algebraic groups are semisimple, Q(G) is isomorphic to Z^n for some n, and so the induced maps can be described by a set of integers called Rost multipliers. We consider various cases of the Kronecker tensor product map between copies of the special linear, special orthogonal, and symplectic groups. We compute the Rost multipliers of the induced map in these examples, ultimately concluding that the Rost multipliers depend only on the dimensions of the underlying vector spaces.
