A’ frutti loro li cognosciarete : gender and genre in a quattrocento altarpiece
Creators: name: Dunlop, Anne Elizabeth
Publisher: name: University of British Columbia
Year: 2008

description: In the Cleveland Museum of Art there is a fifteenth century Italian altarpiece called The Madonna of Humility with the Temptation of Eve, which shows the Virgin Mary nursing the Child with Eve lying below her, almost completely naked and the snake between her thighs. Nothing is known about the circumstances of the panel's commission or provenance, save that art historical consensus attributes it to a "minor master" from the Papal Marches called Carlo da Camerino and dates it to about 1400. While related to an established tradition linking Mary and Eve, this image is a departure from older representations of the theme; compared to the few iconographically similar works that have come down to us, the image of the Cleveland panel seems to present a different relation to the viewer, stressing the bipolar nature of these two females figures through, among other things, the careful differentiation of their physical bodies. Clearly anomalous in the received canon of Trecento and Quattrocento works, the Cleveland panel creates immediate questions about the place of gender and the female body in the imagery of Renaissance altarpieces. This thesis seeks to determine what, as an altarpiece, The Madonna of Humility with the Temptation of Eve could offer its viewers in fifteenth-century debates about gender and female sexuality, by focusing on two aspects which shaped both the panel and its viewers' responses: the dichotomous and contradictory nature of constructions of femininity, and the conventions and expectations of the altarpiece as a genre.

description: We consider a plasma of massless particles undergoing Bjorken expansion, mimicking the matter created in ultra-relativistic heavy ion collisions. We study the transition to hydrodynamics using kinetic theory in the relaxation time approximation. By allowing the relaxation time to depend on time, we can monitor the speed of the transition from the collisionless regime to hydrodynamics. By using a special set of moments of the momentum distribution, we reduce the kinetic equation to a coupled mode problem which encompasses all versions of second order viscous hydrodynamics for Bjorken flows. This coupled mode problem is analysed first using techniques of linear algebra. Then we transform this two mode problem into a single non linear differential equation and proceed to a fixed point analysis. We identify an attractor solution as the particular solution of this non linear equation that joins two fixed points: one corresponding to the collisionless, early time regime, the other corresponding to late time hydrodynamics. We exploit the analytic solution of this equation in order to test several approximations and to identify generic features of the transition to hydrodynamics. We argue that extending the accuracy of hydrodynamics to early time, i.e. to the region of large gradients, amounts essentially to improve the accuracy of the location of the collisionless fixed point. This is demonstrated by showing that a simple renormalisation of a second order transport coefficient puts the free streaming fixed point at the right location, and allows us to reproduce accurately the full solution of the kinetic equation within second order viscous hydrodynamics, even in regimes far from local equilibrium.

Analysis of Reflection Electron Energy Loss Spectra (REELS) for Determination of the Dielectric Function of Solids: Fe, Co, Ni
Creators: name: Werner, Wolfgang S. M.
Publisher: name: arXiv
Year: 2006
Subjects: subject: Materials Science (cond-mat.mtrl-sci)
subject: FOS: Physical sciences

description: A simple procedure is developed to simultaneously eliminate multiple scattering contributions from two reflection electron energy loss spectra (REELS) measured at different energies or for different experimental geometrical configurations. The procedure provides the differential inverse inelastic mean free path (DIIMFP) and the differential surface excitation probability (DSEP). The only required input parameters are the differential cross section for elastic scattering and a reasonable estimate for the inelastic mean free path (IMFP). No prior information on surface excitations is required for the deconvolution. The retrieved DIIMFP and DSEP can be used to determine the dielectric function of a solid by fitting the DSEP and DIIMFP to theory. Eventually, the optical data can be used to calculate the (differential and total) inelastic mean free path and the surface excitation probability. The procedure is applied to Fe, Co and Ni and the retrieved optical data as well as the inelastic mean free paths and surface excitation parameters derived from it are compared to values reported earlier in the literature. In all cases, reasonable agreement is found between the present data and the earlier results, supporting the validity of the procedure.

Multicomponent Diffusion-Weighted MRI: Revealing Microenvironment Changes in Degenerative Spinal Cord
Creators: name: Gao, Jin
Publisher: name: University of Illinois at Chicago
Year: 2023

description: Diffusion-weighted Imaging (DWI) is a well-established magnetic resonance imaging technique commonly used in studying neurodegeneration in the brain and spinal cord. The DWI techniques have predominantly focused on brain investigations and the studies on spinal cord share technical similarities with those conducted on the brain. However, there are notable differences between the brain and spinal cord. The brain exhibits greater isotropy, whereas the spinal cord demonstrates more anisotropy. Consequently, specific DWI techniques that take advantage of the spinal cord's anisotropic nature may outperform the commonly used techniques designed for isotropic objects. Unfortunately, research on the application of these specific DWI techniques in the spinal cord is limited. Hence, the aim of this dissertation is to explore this new regime and expand the knowledge of a specialized DWI technique, ultra-high b-value DWI, for the classification of healthy and Amyotrophic Lateral Sclerosis (ALS) affected mouse spinal cords.

To address the knowledge gap surrounding the utilization of ultra-high b-value techniques, a systematic study incorporating simulation, phantom, ex vivo, and in vivo investigations was conducted. The dissertation begins with simulation and phantom studies, which validated the feasibility of employing regularized (Non-negative Least Squares) NNLS methods for decomposing DWI data. Subsequently, the ex vivo study demonstrated the potential to encode diffusion contrast from ultra-high b-values onto DW images. Moreover, the ex vivo data was analyzed using the well-established L2-norm regularized NNLS method in Myelin Water Imaging, successfully capturing microenvironmental changes in mouse spinal cords caused by ALS.

However, the L2-norm regularization exhibited an over-smoothing effect in the results. To address this issue, a novel L1-norm regularized NNLS method was introduced and applied to analyze the same ex vivo datasets. Additionally, the decomposition nature of NNLS methods facilitated another study that explored the impact of low b-values on DW signals. Drawing upon the knowledge and insights gained from the preceding studies, DWI protocols incorporating ultra-high b-values were developed for in vivo mouse spinal cord imaging. The results obtained using the novel L1-norm regularized NNLS method on the in vivo data unveiled new imaging indices for classifying ventral roots in wild-type and ALS-affected animals at the pre-symptomatic stage (P75) and early symptomatic stage (P90). Furthermore, lower signal intensities were observed in the ventral roots of ALS-affected spinal cords, and the results obtained from the proposed L1-norm regularized NNLS method affirmed a shift towards higher diffusion coefficient ranges in weight distributions. These findings may potentially describe changes in the local environment as the disease progresses.

description: The space-based gravitational wave (GW) detector LISA is expected to observe signals from a large population of compact object binaries, comprised predominantly of white dwarfs, in the Milky Way. Resolving individual sources from this population against its self-generated confusion noise poses a major data analysis problem. We present an iterative source estimation and subtraction method to address this problem based on the use of particle swarm optimization (PSO). In addition to PSO, a novel feature of the method is the cross-validation of sources estimated from the same data using different signal parameter search ranges. This is found to greatly reduce contamination by spurious sources and may prove to be a useful addition to any multi-source resolution method. Applied to a recent mock data challenge, the method is able to find $O(10^4)$ Galactic binaries across a signal frequency range of $[0.1,15]$ mHz, and, for frequency $\gtrsim 4$ mHz, reduces the residual data after subtracting out estimated signals to the instrumental noise level.

Ethical problems encountered by public health nursing administrators
Creators: name: Cutler, Allison Jean
Publisher: name: University of British Columbia
Year: 2008

description: The intent of this study was to explore the ethical problems encountered in public health nursing administration. A qualitative study, incorporating critical incident design, was conducted. The data was collected during audio-taped interviews with twenty public health nursing administrators. The data were analyzed, utilizing the technique of content analysis, to identify common themes. Themes were identified in relation to the ethical problems experienced, the public health administrators' responses to the ethical problem, and the variables which influenced the public health administrators' experience of the problem. The themes which emerged in relation to the ethical problems experienced were categorized according to the sources of nursing obligations, as identified by the Canadian Nurses Association [CNA] (1991). These obligations included clients, nursing roles and responsibilities, nursing ethics and society, and the nursing profession. The majority of ethical problems related to nursing obligations to clients and nursing roles and responsibilities. One ethical problem was identified in relation to nursing ethics and society; no problems were identified in relation to the nursing profession. Three of the participants did not perceive that they had experienced an ethical problem in their administrative practice in the past year. The participants' responses were categorized according to how they acted, felt or thought about the ethical problem they experienced. The responses included stress, regret and uncertainty, utilization of a decision making approach, values clarification, failure to act, and the use of personal and external resources. The variables which influenced the participants' experience of the ethical problem were categorized according to personal, professional, organizational, and system variables. The findings indicated that: the public health nursing administrators who participated in this study were able to identify ethical problems in their practice and to retrospectively analyze their experiences; the majority of public health nursing administrators in this study identified ethical problems related to lack of autonomy and conflicting role obligations; the public health nursing administrators all found the experience of the ethical problem difficult; the majority of public health nursing administrators did not feel supported in their experience of the ethical problem; the responses of public health nursing administrators showed a lack of systematic referral to ethical principles as they worked to resolve the problem; and organizational factors existed which made the experience of the ethical problem particularly difficult for public health nursing administrators who held their position on an acting basis. Implications for nursing practice, education and research arising from these findings were outlined.

We first rederive the known results on $M_h$-integrated functions using Jet Calculus techniques, and then we present the evolution equations for extended dihadron fragmentation functions. Our results are relevant for the analysis of experimental measurements of two-particle-inclusive processes at different energies.

Ziel dabei ist es, die Studierenden an das Thema Rollenanalyse heranzuführen und ihnen eine Analysefolie zur Verfügung zu stellen, um die eigenen Praxiserfahrungen reflexiv auf Distanz zu bringen und einen Impuls zu setzen für die Auseinandersetzung mit der eigenen Rollenidentität. Durch die reflexive Distanznahme und den moderierten Austausch mit anderen Rolleninhaber*innen sollen häufig unbewusst ablaufende (emotionale) Reaktionen, Situationsdeutungen und soziale Mechanismen in der schulischen Praxis bewusst gemacht – und damit auch verhandelbar und hinsichtlich ihrer Angemessenheit hinterfragbar – werden. Professionalisierung durch Praxisreflexion ist hier als Ermöglichung einer bewussteren Rollengestaltung bzw. Entwicklung der eigenen Rollenidentität gedacht.

description: We consider the time-delayed coincidence counting of two photons emitted in a cascade by a single particle (atom, molecule, nucleus, etc). The time-dependence of the probability amplitude of the second photon in the cascade has a sharply rising leading edge due to the detection of the first photon, as results from causality. If a macroscopic ensemble of resonant two-level absorbers is placed in the path of the second photon between the radiation source and the detector, the photon absorption does not follow Beer's law due to the time-asymmetric shape of the photon. For very short delay times almost no absorption takes place, even in an optically dense medium. We analyze the propagation of such a second photon in a thick resonant three-level absorber if a narrow electromagnetically induced transparency (EIT) window is present at the center of the absorption line. It is shown that the EIT medium can change the asymmetric time dependence of the photon probability amplitude to a bell shape (EIT filtering). This bell-shaped photon interacts much more efficiently with an other ensemble of two-level absorbers chosen, for example, to store this photon and the information it carries.

description: The YGLO (Yang-Grasso-Lacroix-Orsay) functional is applied for the first time to investigate ground-state properties of different isotopic chains, from Oxygen to Lead. Mean-field Hartree-Fock calculations are carried out to analyze global trends for separation energies, binding energies, radii, neutron skins, and density profiles. We have three objectives: i) we study whether this functional leads to a reasonable description of ground-state properties (despite the fact that it was not adjusted on nuclei) and we discuss the associated limitations; ii) we investigate whether the correct description of the low-density nuclear gas, which is the peculiarity of this functional, has any relevant impact on predictions for nuclei; iii) we connect nuclear energies, radii and density profiles with properties of the corresponding equations of state of infinite matter. In particular, we identify a link existing between the isoscalar effective mass and spatial properties in neutron-deficient nuclei, namely proton radii and tails of proton densities. On the other side, we show that the slope of the symmetry energy is connected with spatial properties in neutron-rich nuclei: the slope computed at saturation density is related to neutron skin thicknesses, as already well known, whereas the slope calculated at lower densities is linked to the tails of neutron densities. The YGLO effective mass turns out to be quite low. Directions to improve this aspect are explored and suggested at the end of the manuscript.

description: We show that the Coulomb blockade in parallel dots pierced by magnetic flux $Φ$ completely blocks the resonant current for any value of $Φ$ except for integer multiples of the flux quantum $Φ_0$. This non-analytic (switching) dependence of the current on $Φ$ arises only when the dot states that carry the current are of the same energy. The time needed to reach the steady state, however, diverges when $Φ\to nΦ_0$.

The reconstruction of skeletal movement: the soft tissue artefact issue

description: In 3D human movement analysis performed using stereophotogrammetric systems and skin markers, bone pose can only be estimated in an indirect fashion. During a movement, soft tissue deformations make the markers move with respect to the underlying bone generating soft tissue artefact (STA). STA has devastating effects on bone pose estimation and its compensation remains an open question.
The aim of this PhD thesis was to contribute to the solution of this crucial issue. Modelling STA using measurable trial-specific variables is a fundamental prerequisite for its removal from marker trajectories.
Two STA model architectures are proposed. Initially, a thigh marker-level artefact model is presented. STA was modelled as a linear combination of joint angles involved in the movement. This model was calibrated using ex-vivo and in-vivo STA invasive measures. The considerable number of model parameters led to defining STA approximations. Three definitions were proposed to represent STA as a series of modes: individual marker displacements, marker-cluster geometrical transformations (MCGT), and skin envelope shape variations. Modes were selected using two criteria: one based on modal energy and another on the selection of modes chosen a priori. The MCGT allows to select either rigid or non-rigid STA components. It was also empirically demonstrated that only the rigid component affects joint kinematics, regardless of the non-rigid amplitude. Therefore, a model of thigh and shank STA rigid component at cluster-level was then defined. An acceptable trade-off between STA compensation effectiveness and number of parameters can be obtained, improving joint kinematics accuracy.
The obtained results lead to two main potential applications: the proposed models can generate realistic STAs for simulation purposes to compare different skeletal kinematics estimators; and, more importantly, focusing only on the STA rigid component, the model attains a satisfactory STA reconstruction with less parameters, facilitating its incorporation in an pose estimator.

description: Coastal sand dunes represent a richness first of all in terms of defense from the sea storms waves and the saltwater ingression; moreover these morphological elements constitute an unique ecosystem of transition between the sea and the land environment.  The research about dune system is a strong part of the coastal sciences, since the last century. Nowadays this branch have assumed even more importance for two reasons: on one side the born of brand new technologies, especially related to the Remote Sensing, have increased the researcher possibilities; on the other side the intense urbanization of these days have strongly limited the dune possibilities of development and fragmented what was remaining from the last century. This is particularly true in the Ravenna area, where the industrialization united to the touristic economy and an intense subsidence, have left only few dune ridges residual still active. In this work three different foredune ridges, along the Ravenna coast, have been studied with Laser Scanner technology. This research didn’t limit to analyze volume or spatial difference, but try also to find new ways and new features to monitor this environment. Moreover the author planned a series of test to validate data from Terrestrial Laser Scanner (TLS), with the additional aim of finalize a methodology to test 3D survey accuracy. Data acquired by TLS were then applied on one hand to test some brand new applications, such as Digital Shore Line Analysis System (DSAS) and Computational Fluid Dynamics (CFD), to prove their efficacy in this field; on the other hand the author used TLS data to find any correlation with meteorological indexes (Forcing Factors), linked to sea and wind (Fryberger's method) applying statistical tools, such as the Principal Component Analysis (PCA).

description: We generalize the derivation of the Wallis formula for $π$ from a variational computation of the spectrum of the Hydrogen atom. We obtain infinite product formulas for certain combinations of gamma functions, which include irrational numbers such as $\sqrt 2$ as well as some nested radicals. We also derive Euler's reflection formula for reciprocals of positive even integers. We show that Bohr's correspondence principle allows us to derive our product formulas and the reflection formula without the need for the limit definition of the gamma function.

Dark Majorana Particles from the Minimal Walking Technicolor
Creators: name: Kouvaris, Chris

description: We investigate the possibility of a dark matter candidate emerging from a minimal walking technicolor theory. In this case techniquarks as well as technigluons transform under the adjoint representation of SU(2) of technicolor. It is therefore possible to have technicolor neutral bound states between a techniquark and a technigluon. We investigate this scenario by assuming that such a particle can have a Majorana mass and we calculate the relic density. We identify the parameter space where such an object can account for the full dark matter density avoiding constraints imposed by the CDMS and the LEP experiments.

What does Canada want? : reactions to the Allaire Report in and out of Quebec as expressed in the written press
Creators: name: Danjoux, Olivier
Publisher: name: University of British Columbia
Year: 2008

description: The theoretical framework of this thesis bases itself essentially upon the respective works of Arendt Lijphart and Karl Deutsch, who have studied how societal cleavages and social communication interact with each other. The present thesis's main focus is the Quebec/English Canadian duality. It uses quantitative analysis to study and compare pan-Canadian reactions to the Allaire Report that was issued by the Quebec Liberal Party in early 1991. The purpose is to try and find out whether the Allaire Report and the proposals it contains have had a divisive effect on Canadian society, and if so, to what extent. The data consists of all issues of the following newspapers over a period of time of exactly one month, from the 22nd of January and the 22nd of February, 1991 : the Calgary Herald, the Chronicle Herald, the Globe and Mail, Le Devoir, the Montreal Gazette, the Vancouver Sun and the Winnipeg Free Press. The analysis bases itself upon (1) the space that each newspaper devotes to the issue (2) the tone and content of the headlines and (3) the frequencies of appearance of certain selected words. Quantitative analysis shows that the gap between Quebec and English Canada is becoming wider. Quebec clearly overestimates English Canada's fragile degree of homogeneity, while English Canada, by increasingly identifying itself to the so-called "rest of Canada", paradoxically acts as if Quebec were the glue that holds the whole country together.

description: The photorecombination spectrum of 48Ti18+ was measured employing the merged electron-ion beams technique at a heavy-ion storage ring. The experimental electron-ion collision energy range 0-80 eV comprises all dielectronic recombination (DR) resonances associated with 2s->2p (Delta N =0) core excitations as well as trielectronic recombination (TR) resonances that involve 2s2->2p2 core double-excitations. At low collision energies DR resonances are observed that are associated with the excitation of metastable 2s2p 3P0 primary ions with nearly infinite lifetime for the isotope 48Ti with zero nuclear spin. For the isotope 47Ti with nonzero nuclear spin hyperfine quenching of these resonances occurs. The procedure for obtaining the associated time constant from a recombination measurement is outlined.

Massive Star Formation in the Galactic Center
Creators: name: Figer, D. F.

Subjects: subject: Astrophysics (astro-ph)

description: The Galactic center is a hotbed of star formation activity, containing the most massive star formation site and three of the most massive young star clusters in the Galaxy. Given such a rich environment, it contains more stars with initial masses above 100 \Msun than anywhere else in the Galaxy. This review concerns the young stellar population in the Galactic center, as it relates to massive star formation in the region. The sample includes stars in the three massive stellar clusters, the population of younger stars in the present sites of star formation, the stars surrounding the central black hole, and the bulk of the stars in the field population. The fossil record in the Galactic center suggests that the recently formed massive stars there are present-day examples of similar populations that must have been formed through star formation episodes stretching back to the time period when the Galaxy was forming.

description: Der hier vorgestellte methodische Input für eine supervisorisch begleitete Biografiearbeit mit angehenden Lehrer*innen ist insbesondere für Reflexionsangebote oder Seminare in der Begleitung von Praxisphasen vorgesehen und zielt auf eine bewusste Auseinandersetzung mit dem emotionalen Erleben im Praxisfeld Schule. Die Biografiearbeit soll ermöglichen, Parallelen zwischen dem Erleben in der schulischen Praxis und in bedeutsamen Phasen der eigenen Biografie zu entdecken und so Zusammenhänge und die Bedingtheit eigener Reaktionsweisen und Erwartungen bewusst zugänglich zu machen. Auf diese Weise werden die aktuellen (emotionalen) Erlebnis- und Reaktionsweisen einer Bearbeitung zugänglich gemacht und es kann selbstkritisch hinterfragt werden, inwieweit diese für das zukünftige berufliche Handeln als Lehrer*in angemessen oder womöglich auch hinderlich sind. Durch die Perspektiverweiterung können neue Handlungsalternativen entstehen, und die aufgedeckten Bezüge zur eigenen Lebensgeschichte bleiben als Ressource für eine kritische Auseinandersetzung mit der Praxis wie auch sich selbst in dieser Praxis für die Zukunft bestehen.

description: An $n$-ary operation $Q:S^n -> S$ is called an $n$-ary quasigroup of order $|S|$ if in the equation $x_{0}=Q(x_1,...,x_n)$ knowledge of any $n$ elements of $x_0$, ..., $x_n$ uniquely specifies the remaining one. $Q$ is permutably reducible if $Q(x_1,...,x_n)=P(R(x_{s(1)},...,x_{s(k)}),x_{s(k+1)},...,x_{s(n)})$ where $P$ and $R$ are $(n-k+1)$-ary and $k$-ary quasigroups, $s$ is a permutation, and $10$ arguments. We prove that if the maximum arity of a permutably irreducible retract of an $n$-ary quasigroup $Q$ belongs to $\{3,...,n-3\}$, then $Q$ is permutably reducible.

A Kinetic Model for Electron-Ion Transport in Warm Dense Matter

description: We present a model for electron-ion transport in Warm Dense Matter that incorporates Coulomb coupling effects into the quantum Boltzmann equation of Uehling and Uhlenbeck through the use of a statistical potential of mean force. Although this model has been derived rigorously in the classical limit [S.D. Baalrud and J. Daligault, Physics of Plasmas 26, 8, 082106 (2019)], its quantum generalization is complicated by the uncertainty principle. Here we apply an existing model for the potential of mean force based on the quantum Ornstein-Zernike equation coupled with an average-atom model [C. E. Starrett, High Energy Density Phys. 25, 8 (2017)]. This potential contains correlations due to both Coulomb coupling and exchange, and the collision kernel of the kinetic theory enforces Pauli blocking while allowing for electron diffraction and large-angle collisions. By solving the Uehling-Uhlenbeck equation for electron-ion relaxation rates, we predict the momentum and temperature relaxation time and electrical conductivity of solid density aluminum plasma based on electron-ion collisions. We present results for density and temperature conditions that span the transition from classical weakly-coupled plasma to degenerate moderately-coupled plasma. Our findings agree well with recent quantum molecular dynamics simulations.
