Women writers and the study of natural history in nineteenth-century Canada
Creators: name: Matthews, Charity Christine
Publisher: name: University of British Columbia
Year: 2013

description: During the nineteenth century, women in Britain and Canada read about natural history, wrote about it, drew it, and collected it alongside their male counterparts. Produced during a time when it was widely accepted that, as Charles Darwin succinctly stated in The Descent of Man (1871), “Man is more powerful in mind and body than woman” (597), women’s contributions to the natural sciences were often overshadowed or ignored. However, women in the nineteenth century in Canada contributed greatly to the development of knowledge of meteorology, botany, zoology, and ornithology. Indeed, their work sometimes anticipated the modern ecological critique of a preoccupation with cultivating and controlling nature in the names of science and capitalism. This dissertation examines the intellectual, literary, and scientific experiences of nature for women in nineteenth-century Canada, namely the geographical region known as Upper Canada (1791-1841), Canada West (1841-1867), or Ontario (1867-present), and investigates the language and scientific systems that were available to women to describe those experiences. Instead of struggling amateurs restricted to domestic pursuits, nineteenth-century women writers were sometimes pioneering naturalists, popularizers of science, and innovators of a hybrid approach to the language of natural history. Naturalist observations and the negotiation of how to understand nature, seeing nature as hostile, neutral, or divine, were central elements in the creation of the nineteenth-century woman’s identity. The writers examined in this study— Anna Jameson, Anne Langton, Susanna Moodie, Mary Ann Shadd, Harriet Sheppard, Frances Stewart, and Catharine Parr Traill— read scientific and literary texts and used the information to shape their understandings of the natural world, the weather, flora, and fauna. As educated, reflective thinkers, they use their letters, journals, emigration pamphlets, and autobiographical narratives to respond to systems of Linnaean classification as well as to participate in discussions which anticipated the shift later in the century to ecological perspectives inspired by Darwinism. This study examines the ways in which women writers were actively exploring shifting conceptions of the natural world as it developed alongside settlement and seeks to offer new ways of approaching the work of Jameson, Langton, Moodie, Shadd, Sheppard, Stewart, and Traill. In chapters devoted to meteorology, botany, zoology, and ornithology, this thesis rethinks both nature writing and women’s writing in Canada.

description: A novel method of producing intense short wavelength radiation from relativistic electrons is described. The electrons are periodically bunched at the wavelength of interest enabling in-phase super-radiant emission that is orders of magnitude more intense than that of unbunched electrons. The periodic bunching is achieved in steps beginning with an array of beamlets emitted from a nanoengineered field emission array. The beamlets are then manipulated and converted to a longitudinal density modulation via a transverse to longitudinal emittance exchange. Periodic bunching at short wavelength is shown to be possible, and the partially coherent x-ray properties produced by Inverse Compton scattering from an intense laser are estimated for an example at 13 nm wavelength using a 1.5 MeV electron beam.

description: We study a seesaw-type extension of the Standard Model in which the symmetry group is enlarged by a global U(1). We introduce adequate scalar and fermion representations which naturally explain the smallness of neutrino masses. With the addition of a viable scalar Dark Matter candidate, an original scenario of leptogenesis emerges. We solve the relevant set of Boltzmann equations and show how leptogenesis can be successfully implemented at the TeV scale. The constraints on the scalar mass spectrum are derived and the Dark Matter phenomenology is discussed.

Nonlinear viscous damping and gravitational wave detectability of the f-mode instability in neutron stars

description: We study the damping of the gravitational radiation-driven f-mode instability in rotating neutron stars by nonlinear bulk viscosity in the so-called supra-thermal regime. In this regime the dissipative action of bulk viscosity is known to be enhanced as a result of nonlinear contributions with respect to the oscillation amplitude. Our analysis of the f-mode instability is based on a time-domain code that evolves linear perturbations of rapidly rotating polytropic neutron star models. The extracted mode frequency and eigenfunctions are subsequently used in standard energy integrals for the gravitational wave growth and viscous damping. We find that nonlinear bulk viscosity has a moderate impact on the size of the f-mode instability window, becoming an important factor and saturating the mode's growth at a relatively large oscillation amplitude. We show similarly that nonlinear bulk viscosity leads to a rather high saturation amplitude even for the r-mode instability. In addition, we show that the action of bulk viscosity can be significantly mitigated by the presence of superfluidity in neutron star matter. Apart from revising the f-mode's instability window we provide results on the mode's gravitational wave detectability. Considering an f-mode-unstable neutron star located in the Virgo cluster and assuming a mode amplitude at the level allowed by bulk viscosity, we find that the emitted gravitational wave signal could be detectable by advanced ground-based detectors such as Advanced LIGO/Virgo and the Einstein Telescope.

description: In Deutschland hat sich die gesellschaftliche Akzeptanz von LGBTQI*-Menschen in den vergangenen Jahrzehnten deutlich verbessert und die rechtliche Gleichstellung am Arbeitsmarkt wurde durch das Allgemeine Gleichbehandlungsgesetz gestärkt. Dennoch berichten knapp 30 Prozent derjenigen, die sich der Gruppe der LGBTQI*-Menschen zuordnen, von Benachteiligungen im Arbeitsleben. Dies ist das Ergebnis einer Befragung des Sozio-oekonomischen Panels und der Universität Bielefeld. Ebenso ist fast ein Drittel der LGBTQI*- Menschen nicht oder nur teilweise gegenüber Kolleg*innen geoutet. Insbesondere Trans*-Menschen berichten häufig von Diskriminierungserfahrungen im Arbeitsleben. Für LGBTQI*- Menschen, die durchschnittlich höher gebildet sind als die heterosexuelle Bevölkerung, gehört ein offenes Betriebsklima ihnen gegenüber zu den wichtigsten Kriterien für die Wahl eines Arbeitgebers. Ein diskriminierungsarmes Arbeitsumfeld reduziert kurz- und langfristige Arbeitsmarktnachteile von (potentiellen) Beschäftigten und erhöht die Attraktivität von Unternehmen für LGBTQI*-Menschen.

description: We use a single trapped 40Ca+ ion as a resonant, polarization-sensitive absorber to detect and characterize the entanglement of tunable narrowband photon pairs from a spontaneous parametric down-conversion source. Single-photon absorption is marked by a quantum jump in the ion and heralded by coincident detection of the partner photon. For three polarization basis settings of absorption and detection of the herald, we find maximum coincidences always for orthogonal polarizations. The polarization entanglement is further evidenced by tomographic reconstruction of the biphoton quantum state.

Survival probability of an immobile target surrounded by mobile traps

Year: 2012

description: We study analytically, in one dimension, the survival probability $P_{s}(t)$ up to time $t$ of an immobile target surrounded by mutually noninteracting traps each performing a continuous-time random walk (CTRW) in continuous space. We consider a general CTRW with symmetric and continuous (but otherwise arbitrary) jump length distribution $f(η)$ and arbitrary waiting time distribution $ψ(τ)$. The traps are initially distributed uniformly in space with density $ρ$. We prove an exact relation, valid for all time $t$, between $P_s(t)$ and the expected maximum $E[M(t)]$ of the trap process up to time $t$, for rather general stochastic motion $x_{\rm trap}(t)$ of each trap. When $x_{\rm trap}(t)$ represents a general CTRW with arbitrary $f(η)$ and $ψ(τ)$, we are able to compute exactly the first two leading terms in the asymptotic behavior of $E[M(t)]$ for large $t$. This allows us subsequently to compute the precise asymptotic behavior, $P_s(t)\sim a\, \exp[-b\, t^θ]$, for large $t$, with exact expressions for the stretching exponent $θ$ and the constants $a$ and $b$ for arbitrary CTRW. By choosing appropriate $f(η)$ and $ψ(τ)$, we recover the previously known results for diffusive and subdiffusive traps. However, our result is more general and includes, in particular, the superdiffusive traps as well as totally anomalous traps.

description: Impossibility of finding local realistic models for quantum correlations due to entanglement is an important fact in foundations of quantum physics, gaining now new applications in quantum information theory. We present an in-depth description of a method of testing the existence of such models, which involves two levels of optimization: a higher-level non-linear task and a lower-level linear programming (LP) task. The article compares the performances of the existing implementation of the method, where the LPs are solved with the simplex method, and our new implementation, where the LPs are solved with a matrix-free interior point method. We describe in detail how the latter can be applied to our problem, discuss the basic scenario and possible improvements and how they impact on overall performance. Significant performance advantage of the matrix-free interior point method over the simplex method is confirmed by extensive computational results. The new method is able to solve problems which are orders of magnitude larger. Consequently, the noise resistance of the non-classicality of correlations of several types of quantum states, which has never been computed before, can now be efficiently determined. An extensive set of data in the form of tables and graphics is presented and discussed. The article is intended for all audiences, no quantum-mechanical background is necessary.

title: Essays on migration and housing
Creators: name: Oladiran, Olayiwola Oladipo
Publisher: name: University of Reading

description: Migration has remained a significant global concern which has engendered sentiments from international organisations, policy makers, scholars, the media and the citizenry; and housing is one of the major components of the migration-related debates. Some of the migration and housing-related debates are however based on anecdotal arguments rather than being evidence-based. This thesis therefore aims to expand the frontiers of the migration debate by providing evidence-based insight on the migration phenomenon and spotlighting its effects on the housing market. This research begins by developing a gravity framework to test the resistance of global migration to the economic forces of gravity. Next, the study examines the potential links between migration policy changes and housing market shocks. A theoretical framework is developed to capture these potential effects, and the framework is tested using different empirical approaches and methods. The empirical analysis concludes with a comparison of the housing tenure outcomes of natives and generations of non-natives which improves insight on the variation in the housing patterns of natives and non-natives. The primary study areas in this thesis provide insight on migration and the housing market which can significantly improve the quality of the on-going migration-related debates and policy formulation. The findings in this research confirm that the economic force of gravity is a key driver of global migration flow. This implies that there is a need to address global inequality in order to minimise the unhealthy pace of migration flow from developing countries to developed countries, particularly when these developed countries are surrounded by developing countries. The research also reveals that migration restrictions do not necessarily imply adverse impact for immigrants, rather the restrictive migration policy framework provides a sustainable basis for the selection of immigrants of higher socio-economic status which makes them more likely to make a faster transition on the housing ladder compared to immigrants in a more liberalised migration framework. The restrictive framework also has the potential to increase the prospects of social and economic integration of immigrant.

description: We find matrix factorization corresponding to an anti-diagonal in ${\mathbb C}P^1 \times {\mathbb C}P^1$, and circle fibers in weighted projective lines using the idea of Chan and Leung of Strominger-Yau-Zaslow transformations. For the tear drop orbifolds, we apply this idea to find matrix factorizations for two types of potential, the usual Hori-Vafa potential or the bulk deformed (orbi)-potential. We also show that the direct sum of anti-diagonal with its shift, is equivalent to the direct sum of central torus fibers with holonomy $(1,-1)$ and $(-1,1)$ in the Fukaya category of ${\mathbb C}P^1 \times {\mathbb C}P^1$, which was predicted by Kapustin and Li from B-model calculations.

description: We consider a recently proposed supersymmetric radiative seesaw model which is coupled with the minimal supergravity. The conventional R parity and $Z_2$ invariance are imposed, which ensures the existence of a multi-component dark matter system. We assume that the pair of the lightest neutralino $\tildeχ$ and the fermionic component $\tildeξ$ of the inert Higgs supermultiplet is dark matter. If $\tildeξ$ is lighter than $\tildeχ$, and the lightest neutral inert Higgs boson is kinematically forbidden to decay (third dark matter), the allowed region in the $m_0{\rm \mathchar`-}M_{1/2}$ plane increases considerably, where $m_0$ and $M_{1/2}$ are the universal soft-supersymmetry-breaking scalar and gaugino mass, respectively, although the dominant component of the multi-component dark matter system is $\tildeχ$. There is a wide allowed region above the recent LHC limit.

description: We discuss the unusual critical behavior of a generalized XY model containing both 2π-periodic and π-periodic couplings between sites. The presence of vortices and half-vortices allows for single-particle condensate and pair-condensate phases. Using a field theoretic formulation and worm algorithm Monte Carlo simulations, we show that in two dimensions it is possible for the system to pass directly from the disordered (high temperature) phase to the single particle (quasi)-condensate via an Ising transition, a situation reminiscent of the `deconfined criticality' scenario.

A Formalization of Social Requirements for Human Interactions with Service Protocols

description: Collaboration models and tools aim at improving the efficiency and effectiveness of human interactions. Although social relations among collaborators have been identified as having a strong influence on collaboration, they are still insufficiently taken into account in current collaboration models and tools. In this paper, the concept of service protocols is proposed as a model for human interactions supporting social requirements, i.e., sets of constraints on the relations among interacting humans. Service protocols have been proposed as an answer to the need for models for human interactions in which not only the potential sequences of activities are specified-as in process models-but also the constraints on the relations among collaborators. Service protocols are based on two main ideas: first, service protocols are rooted in the service-oriented architecture (SOA): each service protocol contains a service-oriented summary which provides a representation of the activities of an associated process model in SOA terms. Second, a class-based graph-referred to as a service network schema-restricts the set of potential service elements that may participate in the service protocol by defining constraints on nodes and constraints on arcs, i.e., social requirements. Another major contribution to the modelling of human interactions is a unified approach organized around the concept of service, understood in a broad sense with services being not only Web services, but also provided by humans.

description: We present a novel approximation scheme for the treatment of strongly correlated electrons in arbitrary crystal lattices. The approach extends the well-known dynamical mean field theory to include nonlocal two-site correlations of arbitrary spatial extent. We extract the nonlocal correlation functions from two-impurity Anderson models where the impurity-impurity distance defines the spatial extent of the correlations included. Translational invariance is fully respected by our approach since correlation functions of any two-impurity cluster are periodically embedded to $k$-space via a Fourier transform. As a first application, we study the two-dimensional Hubbard model on a simple-cubic lattice. We demonstrate how pseudogap formation in the many-body resonance at the Fermi level results from the inclusion of nonlocal correlations.

description: Viele europäische Länder haben nach der globalen Finanzkrise 2008/09 Abgaben von Banken eingeführt, um die Finanzinstitute über Abwicklungs- und Restrukturierungsfonds an den Kosten möglicher künftiger Bankenkrisen zu beteiligen. Gleichzeitig kann durch solche Abgaben für Banken ein Anreiz zu einem geringeren Verschuldungsgrad und damit einer stabileren Kapitalstruktur gesetzt werden. Der vorliegende Beitrag untersucht anhand von Bankbilanzdaten, inwieweit Bankenabgaben zu einer geringeren Verschuldung beigetragen haben und welche Rolle die Höhe des Körperschaftsteuersatzes dafür spielt. Denn durch die steuerliche Bevorzugung von Fremdkapital begünstigen höhere Körperschaftsteuersätze eine stärkere Verschuldung. Die empirischen Befunde zeigen, dass Banken in Ländern mit einer Bankenabgabe auf Bankverbindlichkeiten einen geringeren Verschuldungsgrad und damit höhere Kapitalpuffer aufweisen als Banken in Ländern ohne eine solche Abgabe. Je höher der Körperschaftsteuersatz ist, desto weniger reduzieren Bankenabgaben allerdings die Verschuldung. Um die Effektivität regulatorischer Abgaben zu gewährleisten, sollten bei ihrer Ausgestaltung Wechselwirkungen mit anderen Steuern berücksichtigt werden.

description: It is well known that the low energy electron excitations of the curved graphene sheet $Σ$ are solutions of the massless Dirac equation on a 2+1 dimensional ultra-static metric on ${\Bbb R} \times Σ$. An externally applied electric field on the graphene sheet induces a gauge potential which could be mimicked by considering a stationary optical metric of the Zermelo form, which is conformal to the BTZ black hole when the sheet has a constant negative curvature. The Randers form of the metric can model a magnetic field, which is related by a boost to an electric one in the Zermelo frame. We also show that there is fundamental geometric obstacle to obtaining a model that extends all the way to the black hole horizon.

description: We define a new elliptic genus psi on the complex bordism ring. With coefficients in Z[1/2], we prove that it induces an isomorphism of the complex bordism ring modulo the ideal which is generated by all differences P(E)-P(E*) of projective bundles and their duals onto a polynomial ring on 4 generators in degrees 2, 4, 6 and 8. As an alternative geometric description of psi, we prove that it is the universal genus which is multiplicative in projective bundles over Calabi-Yau 3-folds. With the help of the q-expansion of modular forms we will see that for a complex manifold M, the value psi(M) is a holomorphic Euler characteristic. We also compare psi with Krichever-Hoehn's complex elliptic genus and see that their only common specializations are Ochanine's elliptic genus and the chi_y-genus.

Complexes 1 and 2 show similar 0-D structures containing a [Ni3(Hpytty)2]4+ and Anderson-type [AlMo6(OH)5O19]4− /[CrMo6(OH)5O19]4− anions. The [γ-Mo8O26]4− anion was generated in-situ from the [IMo6O24]5− anion in 3, which shows a 3-D coordination structure constructed from 2-D Co-pytty metal–organic layers and γ-Mo8 anions. The results reveal that the POMs play key roles in tuning the diverse architectures of the final complexes. For 1–3, their adsorption properties for MB/GV and their electrochemical activities have been investigated.

A study of changes to the websites of British Columbia wineries between 2004 and 2012
Creators: name: Madhumita, Faria
Publisher: name: University of British Columbia
Year: 2013

description: This study evaluates the changes that took place in British Columbia wineries’ websites from 2004 to 2012. Through a longitudinal content analysis of website features, this research provides a better understanding of the technological status and marketing activities of British Columbia wineries. The first part of this research covers literatures on the wine industry and its e-commerce adoption. An extensive overview of e-commerce adoption models and website strategies were included in this thesis. Through adoption of the Website Stage Model, this study reveals that market integration increases from the basic stage to advanced stages but remains the same across advanced stages. The findings also show that there is an increasing tendency of wineries to complete online transactions on wineries’ websites instead of outsourcing these transactions to third parties. In addition, this study identifies several new and emerging features in the wineries’ websites that will help future research in the wine industry. Wineries will be able to use this research to easily assess their current website stage. This study also provides wineries with information about the level of sophistication of online marketing activities. The current trends illustrated by the data of British Columbia wineries will help wineries move their websites to a more advanced stage. Moreover, the research provides insights for wineries in British Columbia to adopt e-commerce using the industry specific market integration model.

description: Sky surveys represent a fundamental data basis for astronomy. We use them to map in a systematic way the universe and its constituents, and to discover new types of objects or phenomena. We review the subject, with an emphasis on the wide-field imaging surveys, placing them in a broader scientific and historical context. Surveys are the largest data generators in astronomy, propelled by the advances in information and computation technology, and have transformed the ways in which astronomy is done. We describe the variety and the general properties of surveys, the ways in which they may be quantified and compared, and offer some figures of merit that can be used to compare their scientific discovery potential. Surveys enable a very wide range of science; that is perhaps their key unifying characteristic. As new domains of the observable parameter space open up thanks to the advances in technology, surveys are often the initial step in their exploration. Science can be done with the survey data alone or a combination of different surveys, or with a targeted follow-up of potentially interesting selected sources. Surveys can be used to generate large, statistical samples of objects that can be studied as populations, or as tracers of larger structures. They can be also used to discover or generate samples of rare or unusual objects, and may lead to discoveries of some previously unknown types. We discuss a general framework of parameter spaces that can be used for an assessment and comparison of different surveys, and the strategies for their scientific exploration. As we move into the Petascale regime, an effective processing and scientific exploitation of such large data sets and data streams poses many challenges, some of which may be addressed in the framework of Virtual Observatory and Astroinformatics, with a broader application of data mining and knowledge discovery technologies.

description: Vor fünf Jahren suchten rund eine Million Menschen Zuflucht in Deutschland. Bundeskanzlerin Angela Merkel begegnete der Besorgnis in der Bevölkerung darüber mit ihrem bekannten Ausspruch „Wir schaffen das.“ Seitdem hat sich einiges getan. Wie dieser Bericht zeigt, nehmen die Sorgen der hier lebenden Bevölkerung mit Blick auf das Zusammenleben seit 2016 ab. Geflüchtete sorgen sich allerdings zunehmend über Fremdenfeindlichkeit. Gleichzeitig ist ihr Vertrauen in die Schlüsselinstitutionen des Staates hoch, jedoch im Bereich der öffentlichen Verwaltung vergleichsweise geringer. Stellschraube für den Aufbau von gegenseitigem Vertrauen könnte die Förderung persönlicher Kontakte zwischen Geflüchteten und Einheimischen sein. Es zeigt sich jedoch, dass bislang nur etwa die Hälfte der Geflüchteten regelmäßig Kontakt zu Deutschen hat. Gerade unter geflüchteten Frauen ist der Austausch mit Deutschen noch gering. Staatliche Initiativen zur Schaffung diverser sozialer Netzwerke könnten ein wichtiger Schritt zu einem weiteren Zusammenwachsen sein.

ON DEMAND: Five Small Changes to Build and Foster Community in Your Online Course
Creators: name: Smucny, Darlene
Publisher: name: Innovations in Teaching & Learning Conference Proceedings
Year: 2021

description: Even prior to the COVID-19 pandemic, students learning online at a distance (whether synchronously or asynchronously) often reported feeling isolated from other learners and from their instructors. By making small changes in your online course, you can help your students feel more connected with one another & with you (as instructor). You also can foster their emotional connections with course content, class materials and activities. Creating and fostering community in your online course enhances learner engagement, improves motivation, and leads to better learning (Udermann, 2019). Using the “Small Teaching” approach (Lang 2016; Darby & Lang, 2019), I will share 5 small changes which can be easily implemented right now in your online teaching and also incorporated in your plans for future online courses. By creating community in your course, you facilitate equitable and inclusive learning environment for all learners online (Darby 2020). The tips presented may be applied to synchronous and asynchronous online teaching; undergraduate and graduate-level classes, majors and non-majors courses; and modified for all disciplines.

For example, the correction to the Newtonian force between two masses, m and M, a distance L apart (L<

title: Essays on macroeconomics
Creators: name: Liao, Junyi
Publisher: name: London School of Economics and Political Science (LSE)
Year: 2023

description: This thesis comprises three chapters on macroeconomics. Chapter 1 studies over/under-reaction and judgment noise in expectations formation. In forecast surveys of aggregate macroeconomic and financial variables, the correlation between forecast errors and forecast revisions is positive at the consensus level, but negative at the individual level. I argue that noise in predictive judgment can account for the difference. Using forecast survey data, I provide evidence that judgment noise is large enough to reconcile the difference between the two coefficients. The structural parameter measuring over-/underreaction mainly points to underreaction, regardless of whether the model matches correlation coefficients at the individual or aggregate level. Chapter 2 looks at adaptive expectations and over-/under-reaction to new information. It is shown that the occurrence of over- or under-reaction using adaptive expectations is contingent on both the weighting parameter used in forecasts and the persistence of the associated actual variable. Furthermore, compared to the generalized diagnostic expectations model, the adaptive expectations framework can better match the under-reaction to new information for several variables, as measured by the correlations between forecast errors and forecast revisions. This advantage stems from the capacity of adaptive expectations to allow varying degrees of stickiness in expectations. Chapter 3 explores the effects of an earnings-based borrowing constraint on longterm productivity growth and employment within an economy characterized by endogenous growth, nominal rigidities, and the presence of a zero lower bound on the nominal interest rate. My findings indicate a bifurcated impact from the tightening of the borrowing constraint, contingent upon the position of the nominal interest rate. Particularly, when the nominal interest rate is at the zero lower bound, the tightening of borrowing constraints displays a neutral impact on growth but surprisingly leads to a rise in employment.
ON DEMAND: How Social Annotation Brings Back Close Reading and Transforms Your Class Discussion
Creators: name: Narayanan, Vivek
Publisher: name: Innovations in Teaching & Learning Conference Proceedings
Year: 2021

description: In trying to "up my game" with the strangeness of the pandemic teaching circumstance, emboldened and encouraged by the Online Course Primer, I have begun to experiment with various Blackboard-enabled tools--and these have transformed my teaching practice and circumstance as well as the class' awareness of itself as a community. One crucial tool has been the 'anonymous feedback' box, but what I want to focus on in this presentation is my preferred social annotation tool, Perusall. In a nutshell, social annotation tools put the course readings on a platform where students comment on and mark them up along with the instructor throughout the week, responding to and thinking with each other. In this context, the weekly synchronous (or face to face) meeting was no longer the place where I tried to figure out what the students had or had not read, and what I needed to supplement with lecture. Rather, the conversation had already begun and had in fact been going on throughout the week, with students engaged in close reading and discovering deep nuances in the text together, with me coming in from time to time with clarifications and words of encouragement. The video will walk the viewers through some of the functionalities available in Perusall, showing sample assignments as well the ways that students and I use social annotation.
