New geographies, New selves? German Women migrating to the South Island of New Zealand in the l 980s and 1990s
Creators: name: Duhn, Iris
Publisher: name: University Of Tasmania
Year: 2023
Subjects: Early childhood education

description: This is an interdisciplinary study which draws on literature from the fields of feminist theory, feminist geography and social and cultural theory to develop an understanding of how cultural/gender identity manifests in a new cultural environment and what influence past identifications have on the meaning given to concepts of place/space and self in the 'new' environment. My intention is to highlight that the way we imagine ourselves and 'our' places {in this case Germany and New Zealand) influences how 'reality' is constructed. In much of the literature on migration and globalisation it is assumed that the predominant reasons for migration are economic or to escape violence. Other factors, such as the search for a better place for self-development, or the search for a place where the self is imagined to have more autonomy, are less of a focus in migration studies. This thesis is based on the assumption that the German women who participated, did not necessarily immigrate for economic reasons, but rather to find 'space' for themselves. How this 'space' is imagined, depends on how the self is constructed. Within paradigms, such as modernity, that rely on binary oppositions, migration in search of a 'better' place with the hope for a 'new' self attached, might tum out to generate reproductions of past identifications. The search for a 'better' place then becomes the search for familiarity with little space left for encounters with that which is culturally 'different'. New Selves turned out to be old selves, after all. I worked within a postmodern feminist framework, which highlights that the self is a construct. Places, in a similar vein are made up out of a multitude of selves who collectively re-construct what kind of place 'their' society is. Feminist geographers emphasise that in the age of globalisation, the local and the global are increasingly interlinked. From this perspective, immigration becomes a matter of encompassing the 'old' and the 'new', past identifications have to be re-constructed in a different cultural environment to enable the emergence of 'selves' that are both 'new' and 'old'.

Potentially Large One-loop Corrections to WIMP Annihilation

description: We compute one-loop corrections to the annihilation of non--relativistic particles $χ$ due to the exchange of a (gauge or Higgs) boson $ϕ$ with mass $μ$ in the initial state. In the limit $m_χ\gg μ$ this leads to the "Sommerfeld enhancement" of the annihilation cross section. However, here we are interested in the case $μ\lsim m_χ$, where the one--loop corrections are well--behaved, but can still be sizable. We find simple and accurate expressions for annihilation from both $S-$ and $P-$wave initial states; they differ from each other if $μ\neq 0$. In order to apply our results to the calculation of the relic density of Weakly Interacting Massive Particles (WIMPs), we describe how to compute the thermal average of the corrected cross sections. We apply this formalism to scalar and Dirac fermion singlet WIMPs, and show that the corrections are always very small in the former case, but can be very large in the latter. Moreover, in the context of the Minimal Supersymmetric Standard Model, these corrections can decrease the relic density of neutralinos by more than 1%, if the lightest neutralino is a strongly mixed state.

OVERLAPPING SEQUENCE FEATURES OF MAMMALIAN ENHANCERS COORDINATELY CONTROL ENGAGEMENT OF TRANSCRIPTION FACTOR CONSENSUS SITES AND NUCLEOSOMAL OCCUPANCY
Creators: name: BAROZZI, IROS GIACOMO
Publisher: name: Universit� degli Studi di Milano
Year: 2014

description: In mammalian cells transcription factors (TFs) bind only to a small fraction of the available consensus sites in the genome. In particular, they prefer sites embedded in regions of computationally predicted high nucleosomal occupancy. This is compatible with non-exclusive mechanisms of nucleosome-driven TF-binding and nucleosome-mediated masking of TF binding sites, suggesting that TFs, and in particular pioneers, must overcome a strong barrier in order to engage binding. Exploiting the available information for the hematopoietic master regulator Pu.1, we applied machine learning approaches and uncovered the sequence-encoded information that discriminates engaged from non-engaged genomic consensus sites. We identified a minimal set of features which predicts Pu.1 binding with 78% accuracy, among which sequence determinants able to drive nucleosome occupancy were found. Consistent with this, while Pu.1 maintained nucleosome depletion at many thousand cell type-specific enhancers in macrophages, these site are otherwise occupied by nucleosomes in other cell types and in in vitro reconstituted chromatin. As predicted, engaged consensus sites showed higher sequence-encoded nucleosome occupancy compared to the myriad of non-occupied (and likely non-functional) consensus sites that randomly occur in mammalian genomes. The same sequence features selected in machine learning also explains up to 45% of the variability observed in the nucleosome occupancy in cells where Pu.1 is not expressed (a performance equal or better than what achieved by ad hoc models), suggesting that the same information contributes to nucleosome occupancy and positioning. These data reveal a basic organizational principle of mammalian enhancers whereby TF-engagement at its consensus sites and nucleosome occupancy are coordinately controlled by overlapping sequence features. This model also suggests that co-evolution of these features may be crucial to ensure cell-type specific enhancer activation. The nucleosomal patterns at Pu.1-bound sites in macrophages were further characterized, uncovering distinct subtypes with different DNA sequence composition, which mirror distinctive nucleosomal configurations either in the presence or in the absence of Pu.1.

description: In the present work we propose that a one-dimensional quantum heterostructure composed of magnetic and non-magnetic atomic sites can be utilized as a spin filter for a wide range of applied bias voltage. A simple tight-binding framework is given to describe the conducting junction where the heterostructure is coupled to two semi-infinite one-dimensional non-magnetic electrodes. Based on transfer matrix method all the calculations are performed numerically which describe two-terminal spin dependent transmission probability along with junction current through the wire. Our detailed analysis may provide fundamental aspects of selective spin transport phenomena in one-dimensional heterostructures at nano-scale level.

description: We have then searched for preferential orientations of faint galaxies in the Coma cluster (down I_Vega~-11.5). By applying a deconvolution method to deep u* and I band images of the Coma cluster, we were able to recover orientations down to faint magnitudes. No preferential orientations are found in more than 95% of the cluster, and the brighter the galaxies, the fewer preferential orientations. The minor axes of late type galaxies are radially oriented along a northeast -southwest direction and are oriented north-south in the western X-ray sub- structures. For early type galaxies, in the western regions showing significant preferential orientations, galaxy major axes are oriented perpendicularly to the north-south direction. In the eastern significant region and close to NGC 4889, galaxy major axes also point toward the 2 cluster dominant galaxies. In the southern significant regions, galaxy planes are tangential with respect to the clustercentric direction, except close to (alpha=194.8, delta=27.65) where the orientation is close to -15deg. Part of the orientations of the minor axes of late type galaxies and of the major axes of early type galaxies can be explained by a tidal torque model applied to cosmological filaments and local merging directions. Another part (close to NGC4889) can be accounted for by collimated infalls. For early type galaxies, the (alpha=194.8, delta=27.65) region shows orientations that probably result from processes involving induced star formation.

description: We consider a driven quantum particle in the strong friction regime described by the quantum Smoluchowski equation. We derive Crooks and Jarzynski type relations for the reduced quantum system by properly generalizing the entropy production to take into account the non-Gibbsian character of the equilibrium distribution. In the case of a nonequilibrium steady state, we obtain a quantum version of the Hatano-Sasa relation. We, further, propose an experiment with driven Josephson junctions that would allow to investigate nonequilibrium entropy fluctuations in overdamped quantum systems.

We found various kinds of nontrivial solutions, by applying a similar technique which was used to seek noncommutative solitons in noncommutative scalar field theories. Some of those solutions correspond to bubbles of spacetimes, or represent dimensional reduction. The solution which interpolates $G_{μν}=0$ and Minkowski metric is also found. All solutions we obtained are non-perturbative in the noncommutative parameter $θ$, therefore they are different from solutions found in other contexts of noncommutative theory of gravity and would have a close relation to quantum gravity.

description: We characterize the monomial complete intersections in three variables satisfying the Weak Lefschetz Property (WLP), as a function of the characteristic of the base field. Our result presents a surprising, and still combinatorially obscure, connection with the enumeration of plane partitions. It turns out that the rational primes p dividing the number, M(a,b,c), of plane partitions contained inside an arbitrary box of given sides a,b,c are precisely those for which a suitable monomial complete intersection (explicitly constructed as a bijective function of a,b,c) fails to have the WLP in characteristic p. We wonder how powerful can be this connection between combinatorial commutative algebra and partition theory. We present a first result in this direction, by deducing, using our algebraic techniques for the WLP, some explicit information on the rational primes dividing M(a,b,c).

description: The problem of maximum-likelihood (ML) estimation of discrete tree-structured distributions is considered. Chow and Liu established that ML-estimation reduces to the construction of a maximum-weight spanning tree using the empirical mutual information quantities as the edge weights. Using the theory of large-deviations, we analyze the exponent associated with the error probability of the event that the ML-estimate of the Markov tree structure differs from the true tree structure, given a set of independently drawn samples. By exploiting the fact that the output of ML-estimation is a tree, we establish that the error exponent is equal to the exponential rate of decay of a single dominant crossover event. We prove that in this dominant crossover event, a non-neighbor node pair replaces a true edge of the distribution that is along the path of edges in the true tree graph connecting the nodes in the non-neighbor pair. Using ideas from Euclidean information theory, we then analyze the scenario of ML-estimation in the very noisy learning regime and show that the error exponent can be approximated as a ratio, which is interpreted as the signal-to-noise ratio (SNR) for learning tree distributions. We show via numerical experiments that in this regime, our SNR approximation is accurate.

description: The calculation of the heating rate of cold atoms in vibrating traps requires a theory that goes beyond the Kubo linear response formulation. If a strong "quantum chaos" assumption does not hold, the analysis of transitions shows similarities with a percolation problem in energy space. We show how the texture and the sparsity of the perturbation matrix, as determined by the geometry of the system, dictate the result. An improved sparse random matrix model is introduced: it captures the essential ingredients of the problem, and leads to a generalized variable range hopping picture.

Pitcher plant, Sarracenia purpurea L., as an ecosystem
Creators: name: Laird, Deborah Diemand
Publisher: name: University of British Columbia
Year: 2011

description: The microecosystems in the leaves of the pitcher plant, Sarracenia purpurea, were studied over a thirty day period. These plants were kept out of doors. One of these plants was later brought into the laboratory and four leaves were studied concurrently with four tubes. These studies were intended to show differences, if any, between leaves studied in the field and those in the laboratory, and between the leaves and an artificial environment. Organisms in all of these vessels were counted and their total biomass and oxygen consumption graphed. Three of the larger organisms found were typical of this species of pitcher plant, one through its entire life cycle and the other two for their larval stages. An interesting finding was that the alga, Microthamnion, seems to inhibit the growth of Tetrahymena, probably due to some extrametabolite. Paramecium was apparently excluded from all leaves in the field. The leaves of the pitcher plant were found to be ideal for the field and laboratory investigation of ecological forces due to their natural occurrance, small size, and rapid turnover of organisms.
Verdi e il Th��tre Italien di Parigi (1845-1856).
Creators: name: VERNAZZA, RUBEN

Year: 2018

description: Negli ultimi decenni gli studiosi si sono ampiamente interessati alla relazione privilegiata fra Giuseppe Verdi e la Francia. Una delle chiavi d?accesso favorite all?argomento � stata l?indagine dei rapporti che il compositore intrattenne con i teatri parigini. Se i casi dell?Op�ra, del Th��tre Lyrique, dei teatri di boulevard sono ormai ben noti, non altrettanto pu� dirsi per il Th��tre Italien. Eppure proprio quest?istituzione, votata alla produzione d?opera italiana in lingua originale, fino alla sua chiusura, nel 1878, fu di gran lunga il palcoscenico parigino che produsse con maggior frequenza e costanza le opere del compositore. Della storia dei legami fra Verdi, la sua musica e il Th��tre Italien, questa tesi si propone di studiare la fase iniziale, cio� l?abbondante decennio compreso fra il 1845 (primo allestimento di Nabucodonosor a Parigi) e il 1855?56 (trionfo locale de Il trovatore). Sulla base di un ricco corpus documentario in buona parte sconosciuto, la prima parte della tesi propone una narrazione storica delle relazioni intercorse fra il compositore e l?istituzione. La struttura diacronica permette di misurare se e come le diverse problematiche scaturite da tali relazioni evolvettero nel tempo: sono indagati aspetti che attengono alla biografia di Verdi, alle dinamiche che orientavano la politica artistica del teatro, alla coeva legislazione sul diritto d?autore, ai dibattiti critici. La seconda parte della tesi affronta problematiche inerenti la produzione e la ricezione delle opere di Verdi, concentrandosi in particolare su due delle componenti di un testo operistico: il libretto e la musica. Lo studio dei materiali esecutivi utilizzati al Th��tre Italien e l?analisi dei discorsi sviluppati in �mbito critico permettono di misurare la tensione creata dalla discrepanza fra le peculiarit� dello stile di Verdi e l?idea tipicamente francese secondo la quale l?opera italiana fosse un genere teatrale privo di qualit� drammatiche ma colmo di melodia vocale esemplare. Con approcci metodologici diversificati, questa tesi mira a due obiettivi: da un lato, chiarire come il legame fra Verdi e il Th��tre Italien incise sugli sviluppi della carriera francese e internazionale del primo e sulla storia istituzione e artistica del secondo; dall?altro lato, illustrare come il contatto con la produzione di Verdi mise in questione, e addirittura modific�, le abitudini e le aspettative tradizionali dei francesi nei confronti dell?opera italiana.

description: We present the results of a strong-lensing analysis of a complete sample of 12 very luminous X-ray clusters at $z>0.5$ using HST/ACS images. Our modelling technique has uncovered some of the largest known critical curves outlined by many accurately-predicted sets of multiple images. The distribution of Einstein radii has a median value of $\simeq28\arcsec$ (for a source redshift of $z_{s}\sim2$), twice as large as other lower-$z$ samples, and extends to $55\arcsec$ for MACS J0717.5+3745, with an impressive enclosed Einstein mass of $7.4\times10^{14} M_{\odot}$. We find that 9 clusters cover a very large area ($>2.5 \sq \arcmin$) of high magnification ($μ> \times10$) for a source redshift of $z_{s}\sim8$, providing primary targets for accessing the first stars and galaxies. We compare our results with theoretical predictions of the standard $Λ$CDM model which we show systematically fall short of our measured Einstein radii by a factor of $\simeq1.4$, after accounting for the effect of lensing projection. Nevertheless, a revised analysis once arc redshifts become available, and similar analyses of larger samples, are needed in order to establish more precisely the level of discrepancy with $Λ$CDM predictions.

description: The electronic properties of interfaces between two different solids can differ strikingly from those of the constituent materials. For instance, metallic conductivity, and even superconductivity, have been recently discovered at interfaces formed by insulating transition metal oxides. Here we investigate interfaces between crystals of conjugated organic molecules, which are large gap undoped semiconductors, i.e. essentially insulators. We find that highly conducting interfaces can be realized with resistivity ranging from 1 to 30 kOhm square, and that, for the best samples, the temperature dependence of the conductivity is metallic. The observed electrical conduction originates from a large transfer of charge between the two crystals that takes place at the interface, on a molecular scale. As the interface assembly process is simple and can be applied to crystals of virtually any conjugated molecule, the conducting interfaces described here represent the first examples of a new class of electronic systems.

Voting choices in an industrial community
Creators: name: Murray, Kenneth Calvin
Publisher: name: University of British Columbia
Year: 2011

description: This work presents an analysis of federal election voting choices in an industrial community. The voting choices were reported by a sample of gainfully employed residents of the community. A segment of the sample, those in unionized jobs in the industrial enterprises of the major employer, is submitted to quantitative analysis. A discussion of the significance of interest group formation and operation provides us with a theoretical basis. As industrial workers are less economically secure, are clustered into a relatively undifferentiated range of jobs, and are more isolated from the broad middle class, they will be more prone to form economic and political interest groups. One aspect of such formation is a high level of support for a worker-oriented and socialistic political party. The member of parliament for the constituency was the candidate of a party that appears to be both socialistic and worker oriented, the New Democratic Party (or NDP). Voting choices in favor of this candidate are understood in terms of our theory. They are studied by dividing our respondents by social characteristics. These social characteristics are of three kinds: general vital characteristics, (age, length of community residence, and place of birth), off-work characteristics (religious group membership and participation), and work-defined characteristics, (type of enterprise, union, and skill level). The general social characteristics are assumed to indicate access to community worker political culture. Off-work characteristics are important because they might supply individuals with social identities which override such a culture. At-work characteristics may provide issues that are quickly transformed into social identities influencing voting, given rationality, local worker culture, and the lack of overriding identities. When general and work-defined characteristics are used to study voting choices, a well-defined pattern is found. High rates of NDP support are associated with general vital characteristics that indicate higher access to community and regional political culture, and work-related characteristics that indicate "typical industrial workers" of the nineteenth and early twentieth centuries. When the characteristics are studied in combination, complex patterns are found.

description: The lifetime of localized surface plasmon plays an important role in many aspects of plasmonics and its applications. In small metal nanostructures, the dominant mechanism restricting plasmon lifetime is size-dependent Landau damping. We performed quantum-mechanical calculations of Landau damping for the bright surface plasmon mode in a metal nanoshell. In contrast to the conventional model based on the electron surface scattering, we found that the damping rate decreases as the nanoshell thickness is reduced. The origin of this behavior is traced to the spatial distribution of plasmon local field inside the metal shell. We also found that, due to interference of electron scattering amplitudes from nanoshell's two metal surfaces, the damping rate exhibits pronounced quantum beats with changing shell thickness.

description: The analytical treatment of nonlinear evolution of the shear-flow-modified current driven ion cyclotron instability and shear-flow-driven ion cyclotron kinetic instabilities of magnetic field--aligned plasma shear flow is presented. Analysis is performed on the base of the nonlinear dispersion equation, which accounts for a new combined effect of plasma turbulence and shear flow. It consists in turbulent scattering of ions across the shear flow with their convection by shear flow and results in enhanced nonlinear broadening of ion cyclotron resonances. This effect is found to lead to the saturation of ion cyclotron instabilities as well as to the development of nonlinear shear flow driven ion cyclotron instability. 52.35.Ra

description: We develop several results on hitting probabilities of random fields which highlight the role of the dimension of the parameter space. This yields upper and lower bounds in terms of Hausdorff measure and Bessel--Riesz capacity, respectively. We apply these results to a system of stochastic wave equations in spatial dimension $k\ge1$ driven by a $d$-dimensional spatially homogeneous additive Gaussian noise that is white in time and colored in space.

Riesz transform and integration by parts formulas for random variables

Subjects: subject: Probability (math.PR)

description: We use integration by parts formulas to give estimates for the $L^p$ norm of the Riesz transform. This is motivated by the representation formula for conditional expectations of functionals on the Wiener space already given in Malliavin and Thalmaier. As a consequence, we obtain regularity and estimates for the density of non degenerated functionals on the Wiener space. We also give a semi-distance which characterizes the convergence to the boundary of the set of the strict positivity points for the density.

Glassy Phase Transition and Stability in Black Holes

description: Black hole thermodynamics, confined to the semi-classical regime, cannot address the thermodynamic stability of a black hole in flat space. Here we show that inclusion of correction beyond the semi-classical approximation makes a black hole thermodynamically stable. This stability is reached through a phase transition. By using Ehrenfest's scheme we further prove that this is a glassy phase transition with a Prigogine-Defay ratio close to 3. This value is well placed within the desired bound (2 to 5) for a glassy phase transition. Thus our analysis indicates a very close connection between the phase transition phenomena of a black hole and glass forming systems. Finally, we discuss the robustness of our results by considering different normalisations for the correction term.

description: We study light scattering by a hedgehog-like and linear disclination topological defects in a nematic liquid crystal by a metric approach. Light propagating near such defects feels an effective metric equivalent to the spatial part of the global monopole and cosmic string geometries. We obtain the scattering amplitude and the differential and total scattering cross section for the case of the hedgehog defect, in terms of the characteristic parameters of the liquid crystal. Studying the disclination case, a cylindrical partial wave method is developed. As an application of the previous developments, we also examine the temperature influence on the localization of the diffraction patterns.

Year: 2009

description: The Poynting vector is an invaluable tool for analysing electromagnetic problems. However, even a rigorous stress-energy tensor approach can still leave us with the question: is it best defined as $\Vec{E} \cross \Vec{H}$ or as $\Vec{D} \cross \Vec{B}$? Typical electromagnetic treatments provide yet another perspective: they regard $\Vec{E} \cross \Vec{B}$ as the appropriate definition, because $\Vec{E}$ and $\Vec{B}$ are taken to be the fundamental electromagnetic fields. The astute reader will even notice the fourth possible combination of fields: i.e. $\Vec{D} \cross \Vec{H}$. Faced with this diverse selection, we have decided to treat each possible flux vector on its merits, deriving its associated energy continuity equation but applying minimal restrictions to the allowed host media. We then discuss each form, and how it represents the response of the medium. Finally, we derive a propagation equation for each flux vector using a directional fields approach; a useful result which enables further interpretation of each flux and its interaction with the medium.

description: Collisions and subsequent decays of higher dimensional branes leave behind three-dimensional branes and anti-branes, one of which could play the role of our universe. This process also leads to the production of one-dimensional branes and anti-branes, however their number is expected to be suppressed. Brane collisions may also lead to the formation of bound states of branes. Their existence does not alter this result, it just allows for the existence of one-dimensional branes captured within the three-dimensional ones.

description: We study the effect of electron-electron interaction on transport through a tunnel-coupled single-channel ring. We find that the conductance as a function of magnetic flux shows a series of interaction-induced resonances that survive thermal averaging. The period of the series is given by the interaction strength $α$. The physics behind this behavior is the blocking of the tunneling current by the circular current. The main mechanism of dephasing is due to circular-current fluctuations. The dephasing rate is proportional to the tunneling rate and does not depend on $α$.

Chaotic Maps, Hamiltonian Flows, and Holographic Methods

description: Holographic functional methods are introduced as probes of discrete time-stepped maps that lead to chaotic behavior. The methods provide continuous time interpolation between the time steps, thereby revealing the maps to be quasi-Hamiltonian systems underlain by novel potentials that govern the motion of a perceived point particle. Between turning points, the particle is strictly driven by Hamiltonian dynamics, but at each encounter with a turning point the potential changes abruptly, loosely analogous to the switchbacks on a mountain road. A sequence of successively deepening switchback potentials explains, in physical terms, the frequency cascade and trajectory folding that occur on the particular route to chaos revealed by the logistic map.
