Reimagining the contemporary office façade for hot climatic zones
Creators: name: Nair, Rohini Rajani
Publisher: name: University of British Columbia
Year: 2017

description: Contemporary facades of the office building typologies are either fully transparent facades or a derivative of one. Having originated in cold countries, these building facades have found their way into the skyline of the hot climatic zones of the world. Representative of progress, peace and prosperity, the transparent facades have started to replace the indigenous architecture of the hot climatic zones despite the well-known problems of the fully glazed façade. This thesis explores the fundamental problems of this type of building envelope that includes questioning of its origins, its materiality and its relevance based on energy for a hot climatic zone. The proposed solution is based on architecture that was already truly sustainable in every way (materially and energetically). This is the pre-industrial architecture, even though been in existence for centuries; it has been increasingly rejected by the developing countries on the grounds of it being visually representative of the old, obsolete and the poor. This thesis goes beyond a simple exploration of the sustainable components of the indigenous architecture to reveal a more holistic approach for the building envelope based on energy, material and form. This approach is formally organized into a potential envelope design methodology for contemporary buildings. This methodology is put to test at the end of the thesis by designing a building envelope based on it. This envelope design tests the feasibility of the methodology at present as well as demonstrates its potential to change the future of building envelope design and construction. It also proves that deriving a façade design from the concepts of pre-industrial architecture will not lead to a façade replicating the past but will be representative of the contemporary times. This thesis is meant to change the perspective towards how we approach the concept of energy and materiality in architecture and also find a better way to integrate the knowledge of the pre-industrial architecture into the contemporary world.
Pedagogical relations of listening and becoming in children's everyday literacies : in conversation with Ted Aoki

Publisher: name: University of British Columbia

description: In this inquiry a sociocultural lens of literacy was applied to acknowledge how research contexts of everyday life are tied to children’s learning and participation in diverse cultural and social situations and settings. In the tradition of reconceptualist curricular theorizing in contexts of early childhood education, this research was aimed at enhancing an awareness of relations of pedagogical listening in teaching situations, especially responsive to ethical possibilities as meaning making for pedagogical change (Aoki, 1978/1980; Pinar, 1994). This inquiry took into account listening to young children as active, knowing participants who bring experiences, insights, and knowledge about their lives and literacies into the classroom. Oriented in hermeneutic curriculum inquiry and narrative-interpretive methodology (Aoki, 1978/1980; Leggo & Sameshima, 2014), the study was located in two Kindergarten classrooms in a major city in Alberta, Canada during one school year, and focused on two students, their teachers, and parents. I explored the pedagogical relations of listening to young children’s everyday lives and literacy experiences across borders and contexts of home and school. Through Aoki’s pedagogical call (Aoki, 1990/2005) to theorize curriculum through re/awakening listening (dwelling with/in sonare), this inquiry aimed to understand: (a) young children’s perceptions of literacies, (b) the experience and meanings of relations of listening and literacy pedagogy in early childhood classrooms, and (c) the ways these relations are acknowledged by young children, teachers, and parents. Through conversational interviews (Chase, 2005; Silverman, 2001), narrative portraits (Ellis, 1998a/2006), informal interactions, and observations (Smith, Duncan & Marshall, 2005), and practices of life writing (Hasebe-Ludt, Chambers, & Leggo, 2009), the inquiry evoked meaning making from the Kindergarten-aged students’ narratives about lived experiences with literacy, including technology. Stories uncovered students’ perspectives and meanings of literacies when in transition from home to school. Parents expressed curiosity about literacies and “what teachers do” in developing relations with their children. Teachers became aware of, and attentive to, tensions in their teaching, especially regarding how they ascribed personal values to teaching practices as well as students’ literacy practices with/in the classroom. Teachers articulated the importance of attentiveness in listening to students’ stories as layered narratives of literacy learning.

description: A coherent description of the anomalous Hall effect is presented that is applicable to pure and disordered systems. This is achieved by an implementation of the Kubo-Středa equation using the fully relativistic Korringa-Kohn-Rostoker method in combination with the coherent potential approximation. Applications to the pure ferromagnets Fe and Ni led to results in full accordance with previous work. For the alloy systems FexPd1-x and NixPd1-x very satisfying agreement with experiment could be achieved for the anomalous Hall conductivity. To interpret these results a detailed discussion of the skew and side-jump scattering processes is given.

description: In this paper, both structural and dynamical stabilities of steady transonic shock solutions for one-dimensional Euler-Poission system are investigated. First, a steady transonic shock solution with supersonic backgroumd charge is shown to be structurally stable with respect to small perturbations of the background charge, provided that the electric field is positive at the shock location. Second, any steady transonic shock solution with the supersonic background charge is proved to be dynamically and exponentially stable with respect to small perturbation of the initial data, provided the electric field is not too negative at the shock location. The proof of the first stability result relies on a monotonicity argument for the shock position and the downstream density, and a stability analysis for subsonic and supersonic solutions. The dynamical stability of the steady transonic shock for the Euler-Poisson equations can be transformed to the global well-posedness of a free boundary problem for a quasilinear second order equation with nonlinear boundary conditions. The analysis for the associated linearized problem plays an essential role.

description: Local helioseismology provides unique information about the subsurface structure and dynamics of sunspots and active regions. However, because of complexity of sunspot regions local helioseismology diagnostics require careful analysis of systematic uncertainties and physical interpretation of the inversion results. We present new results of comparison of the ring-diagram analysis and time-distance helioseismology for active region NOAA 9787, for which a previous comparison showed significant differences in the subsurface sound-speed structure, and discuss systematic uncertainties of the measurements and inversions. Our results show that both the ring-diagram and time-distance techniques give qualitatively similar results, revealing a characteristic two-layer seismic sound-speed structure consistent with the results for other active regions. However, a quantitative comparison of the inversion results is not straightforward. It must take into account differences in the sensitivity, spatial resolution and the averaging kernels. In particular, because of the acoustic power suppression, the contribution of the sunspot seismic structure to the ring-diagram signal can be substantially reduced. We show that taking into account this effect reduces the difference in the depth of transition between the negative and positive sound-speed variations inferred by these methods. Further detailed analysis of the sensitivity, resolution and averaging properties of the local helioseismology methods is necessary for consolidation of the inversion results. It seems to be important that both methods indicate that the seismic structure of sunspots is rather deep and extends to at least 20 Mm below the surface, putting constraints on theoretical models of sunspots.

description: A fully relativistic description of the spin-orbit induced spin Hall effect is presented that is based on Kubo’s linear response formalism. Using an appropriate operator for the spin-current density a Kubo-Středa-like equation for the spin Hall conductivity (SHC) is obtained. An implementation using the Korringa-Kohn-Rostoker band structure method in combination with the coherent potential approximation allow detailed investigations on various alloy systems. A decomposition of the SHC into intrinsic and extrinsic contributions is suggested. Accompanying calculations for the skew-scattering contribution of the SHC using the Boltzmann equation demonstrate the equivalence to the Kubo formalism in the dilute alloy regime and support the suggested decomposition scheme.

description: This chapter examines the effectiveness of mentoring as a developmental tool for the hotel industry. In order to have a greater understanding of the process of developing effective mentoring programs in the hospitality environment, an inductive approach was utilized to conduct this exploratory research. The use of qualitative methodology helped determine the underlying reasons, opinions and motivations behind the use of certain best practices. Data was collected through semi-structured face-to-face interviews that involved 10 hoteliers, including managerial personnel responsible for the training and development of associates. The data analysis was done using thematic analysis to identify, analyze and report meaningful patterns within the data.The analysis of data collected through qualitative interviews provided this research with the ability of contributing to both theory and hospitality practice. Five themes were identified: the role of the mentor, the role of a mentee, the essential factors required for effective mentoring programs, ideal mentoring approaches in the hotel industry, and the benefits of mentoring. To conclude, this study has suggested a model for developing effective formal mentoring programs for hoteliers.

Memory effects in the relaxation of the Gaussian trap model

Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: We investigate the memory effect in a simple model for glassy relaxation, a trap model with a Gaussian density of states. In this model thermal equilibrium is reached at all finite temperatures and therefore we can consider jumps from low to high temperatures in addition to the quenches usually considered in aging studies. We show that the evolution of the energy following the Kovacs-protocol can approximately be expressed as a difference of two monotonously decaying functions and thus show the existence of a so-called Kovacs hump whenever these functions are not single exponentials. It is well established that the Kovacs effect also occurs in the linear response regime and we show that most of the gross features do not change dramatically when large temperature jumps are considered. However, there is one distinguishing feature that only exists beyond the linear regime which we discuss in detail. For the memory experiment with 'inverted' temperatures, i.e. jumping up and then down again, we find a very similar behavior apart from an opposite sign of the hump.

description: A spin projection scheme is presented which allows the decomposition of the electric conductivity into two different spin channels within fully relativistic ab initio transport calculations that account for the impact of spin-orbit coupling. This is demonstrated by calculations of the spin-resolved conductivity of Fe1−xCrx and Co1−xPtx disordered alloys on the basis of the corresponding Kubo-Greenwood equation implemented using the Korringa-Kohn-Rostoker coherent-potential approximation band-structure method. In addition, results for the residual resistivity of diluted Ni-based alloys are presented that are compared to theoretical and experimental ones that rely on Mott’s two-current model for spin-polarized systems. The application of the scheme to deal with the spin-orbit induced spin-Hall effect is discussed in addition.

description: Terroir is the greatest determining factor of all great wines. The acknowledgement of the territory vocation is founded on the research of its peculiarities that determine the uniqueness of that production area. In this paper, results concerning the first contributions to characterize terroir environment components and wines in Cinque Terre National Park are presented and discussed. GIS was used to improve the process of landscape characterization. Several profiles from four distinct production vineyards were selected for full pedological description and analysis. Moreover, a solar-powered field station connected to multiple sensors was installed to monitor the soil moisture content and temperature. Finally, the wines (Cinque Terre DOC) from 2014 vintage of the four distinct production vineyards, in which the soil characterization was performed, were analyzed. Biochemical characteristics and total content of phenols were determined. The analyses conducted highlight a number of distinctive features of soils and wines from Cinque Terre vineyards and the usefulness of an accurate description of soils and wines proprieties in the perspective of the implementation of the official DOC Cinque Terre wines production protocols.

description: We consider a 1-parameter family of self-adjoint extensions of the Hamiltonian for a particle confined to a finite interval with perfectly reflecting boundary conditions. In some cases, one obtains negative energy states which seems to violate the Heisenberg uncertainty relation. We use this as a motivation to derive a generalized uncertainty relation valid for an arbitrarily shaped quantum dot with general perfectly reflecting walls in $d$ dimensions. In addition, a general uncertainty relation for non-Hermitean operators is derived and applied to the non-Hermitean momentum operator in a quantum dot. We also consider minimal uncertainty wave packets in this situation, and we prove that the spectrum depends monotonically on the self-adjoint extension parameter. In addition, we construct the most general boundary conditions for semiconductor heterostructures such as quantum dots, quantum wires, and quantum wells, which are characterized by a 4-parameter family of self-adjoint extensions. Finally, we consider perfectly reflecting boundary conditions for relativistic fermions confined to a finite volume or localized on a domain wall, which are characterized by a 1-parameter family of self-adjoint extensions in the $(1+1)$-d and $(2+1)$-d cases, and by a 4-parameter family in the $(3+1)$-d and $(4+1)$-d cases.

description: Diabetes management has evolved significantly with technological advancements, yet traditional insulin delivery methods remain cumbersome for many patients. Insulin patch pumps offer a breakthrough, promising convenience, improved adherence, and better glycemic control. These devices eliminate the need for multiple daily injections and traditional tubed pumps, offering a user-friendly alternative. However, their adoption depends heavily on regulatory approval. This article examines the regulatory pathways governing insulin patch pumps in the United States and Canada, detailing approval requirements, compliance expectations, and strategic considerations for manufacturers.

description: Experimental measurements of the residual resistivity ρ(x) of the binary-alloy system Fe1−xCrx have shown anomalous concentration dependence which deviates significantly from Nordheim’s rule. In the low (x<10%) Cr concentration regime the resistivity has been found to increase linearly with x until ≈10% Cr where the resistivity reaches a plateau persisting to ≈20% Cr. In this paper we present ab initio calculations of ρ(x) which explain this anomalous behavior and which are based on the Korringa-Kohn-Rostoker method in conjunction with the Kubo-Greenwood formalism. Furthermore we are able to show that the effects of short-range ordering or clustering have little effect via our use of the nonlocal coherent-potential approximation. For the interpretation of the results we study the alloy electronic structure by calculating the Bloch spectral function particularly in the vicinity of the Fermi energy. From the analysis of our results we infer that a similar behavior of the resistivity should also be obtained for iron-rich Fe1−xVx alloys—an inference confirmed by further explicit resistivity calculations. Both of these alloy systems belong to the same branch of the famous Slater-Pauling plot, and we postulate that other alloy systems from this branch should show a similar behavior. Our calculations show that the appearance of the plateau in the resistivity can be attributed to the dominant contribution of minority-spin electrons to the conductivity which is nearly unaffected by the increase in Cr/V concentration x, and we remark that this minority-spin electron feature is also responsible for the simple linear variation in the average moment in the Slater-Pauling plot for these materials.

description: We present an ab initio formalism for the calculation of transport properties in compositionally disordered systems within the framework of the Korringa-Kohn-Rostoker nonlocal coherent potential approximation. Our formalism is based on the single-particle Kubo-Greenwood linear response and provides a natural means of incorporating the effects of short-range order upon the transport properties. We demonstrate the efficacy of the formalism by examining the effects of short-range order and clustering upon the transport properties of disordered AgPd and CuZn alloys.

description: The essays in this collection consider these questions as they draw on methods in the humanities, such as literary criticism, to explore the variety of ways in which genetic and genomic research has contributed to new ways of understanding the human and humanity. The first set of essays explores epigenetics, the study of how non-biological factors, such as environmental inputs, modify the expression of genes, without changing the DNA sequence. Often seen as a corrective for genetic determinism, because its central premise is that varied outcomes can arise from the same genetic starting point, epigenetics, as these essays show, risks other forms of determinism. They demonstrate that science cannot fully or effectively challenge cultural biases, assumptions, and values. The second set of essays focuses on how genetic information about the human engages—sometimes to challenge but more often to reinforce—those biases, assumptions, and values, and the third explores how a more rigorous consideration of questions of justice might change research practices.

Calculations in modified gauge theory : testing some ideas from QCD in a toy model
Creators: name: Thomas, Evan Cameron
Publisher: name: University of British Columbia
Year: 2017

description: We use a deformed “center-stablised” gauge theory, which can be brought into a weak coupling regime while remaining confined and gapped, as a toy model to study some ideas from real QCD. The deformed model has the correct nontrivial θ-dependence and degeneracy of topological sectors conjectured for QCD, and is, apparently, smoothly connected to the strongly coupled undeformed Yang-Mills, so that we can perhaps expect to get some qualitative insights into QCD. We demonstrate the presence of a nondispersive contact term in the topological susceptibility, which contributes with the opposite sign to normal dispersive contributions coming from physical propagating degrees of freedom. We further show that, despite the system being completely gapped with no massless physical degrees of freedom, the system has a Casimir-like, power scaling, dependence on boundaries, in contrast with the naive expectation that a system with only massive degrees of freedom should have a weak (exponentially small) dependence on long distance effects. This behaviour suggests the possibility for a solution for the cosmological dark energy problem coming from the strongly coupled QCD sector on a manifold with a boundary, which would have the correct sign and be of the correct order of magnitude. Next, we investigate the interaction between point-like topological charges (monopoles) and extended sheet-like topological defects (domain walls) in attempt to explain some recent lattice QCD results suggesting that extended topological objects are more important to understanding the relevant field configurations in QCD than the instantons traditionally expected. Finally, we derive the existence of excited metastable vacuum states and calculate their decay rate to the true ground state of the theory, comparing with the expected results discussed years ago in proper QCD. The presence of metastable vacuum states with a nonzero effective θ parameter, like those present in the deformed model, could explain P and CP violation in heavy ion collisions observed on an event by event basis, which seem to average away over many events.

description: The beta 2-adrenergic transmembrane signal transduction was investigated in malignant B-cells from 15 patients with low grade non-Hodgkin's lymphoma as compared with normal lymphocytes of seven healthy adults. The number of beta 2-adrenoceptors and the response of adenylate cyclase (AC) to isoproterenol were slightly decreased in lymphoma cells. The responsiveness of AC to forskolin was 8-fold lower in lymphoma cells, whereas the response to cholera toxin showed no difference. These findings demonstrate an impairment of the beta 2-adrenergic signal transduction in low grade lymphoma cells that particularly affects the function of AC. The comparison with forskolin resistant mutants of an adrenocortical tumor cell line, Y1 (Schimmer et al., J Biol Chem 262: 15521-15526, 1987), suggests that the availability of functional active alpha subunits of stimulatory G proteins (Gs) might be reduced in human B-cell lymphoma, although other mechanisms known to inhibit the AC activity might be involved.

description: In order to investigate the relationship between the local environment and the properties of natal star clusters, we obtained radio observations of 25 star-forming galaxies within 20 Mpc using the Very Large Array (VLA) and the Australia Telescope Compact Array (ATCA). Natal star-forming regions can be identified by their characteristic thermal radio emission, which is manifest in their spectral index at centimeter wavelengths. The host galaxies in our sample were selected based upon their likelihood of harboring young star formation. In star-forming regions, the ionizing flux of massive embedded stars powers the dominant thermal free-free emission of those sources, resulting in a spectral index of α {\gtrsim} -0.2 (where Sν {\propto} να), which we compute. With the current sensitivity, we find that of the 25 galaxies in this sample only five have radio sources with spectral indices that are only consistent with a thermal origin; four have radio sources that are only consistent with a non-thermal origin; six have radio sources whose nature is ambiguous due to uncertainties in the spectral index; and sixteen have no detected radio sources. For those sources that appear to be dominated by thermal emission, we infer the ionizing flux of the star clusters and the number of equivalent O7.5 V stars that are required to produce the observed radio flux densities. The most radio-luminous clusters that we detect have an equivalent of ~7x103 O7.5 V stars, and the smallest only have an equivalent of ~102 O7.5 V stars; thus these star-forming regions span the range of large OB-associations to moderate "super star clusters" (SSCs). With the current detection limits, we also place upper limits on the masses of clusters that could have recently formed...

description: Using a first-principles classical many-body simulation of a Hall bar, we study the necessary conditions for the formation of the Hall potential: (i) Ohmic contacts with metallic reservoirs, (ii) electron-electron interactions, and (iii) confinement to a finite system. By propagating thousands of interacting electrons over million time-steps we capture the build-up of the self-consistent potential, which resembles results obtained by conformal-mapping methods. As shown by a microscopic model of the current injection, the Hall effect is linked to specific boundary conditions at the particle reservoirs.

description: We study the quantum Hall effect (QHE) in graphene based on the current injection model, which takes into account the finite rectangular geometry with source and drain electrodes. In our model, the presence of disorder, the edge-state picture, extended states, and localized states, which are believed to be indispensable ingredients in describing the QHE, do not play an important role. Instead the boundary conditions during the injection into the graphene sheet, which are enforced by the presence of the Ohmic contacts, determine the current-voltage characteristics.

description: We calculate the scattering lengths of Nambu-Goldstone bosons interacting with $D$ mesons in a covariant formulation of chiral perturbation theory, which satisfies heavy-quark spin symmetry and analytical properties of loop amplitudes. We compare our results with previous studies performed using heavy meson chiral perturbation theory and show that recoil corrections are sizable in most cases.

description: For diagnosis of instability in case of ruptures of the lateral ankle joint ligaments a special ultrasound examination technique was established. In 41 patients with acute ruptures and 8 patients with chronic instabilities a prospective preoperative sonographic instability-testing was performed and compared to intraoperative result. A sensitivity of 0.96 for injuries of the lig. fib. tal. ant. and 0.79 for the lig. fib. calc. proves the exactness of this method. This technique is easy to perform and the result can be documented. This examination is accepted by the patients.

description: In this follow up to our recent letter [F. Otto et al., Phys. Rev. Lett. 104, 027005 (2010)], we present a more detailed account of the superconducting transversal flux transformer effect (TFTE) in amorphous (a-)NbGe nanostructures in the regime of strong nonequilibrium in local vortex motion. Emphasis is put on the relation between the TFTE and local vortex dynamics, as the former turns out to be a reliable tool for determining the microscopic mechanisms behind the latter. By this method, a progression from electron heating at low temperatures T to the Larkin-Ovchinnikov effect close to the transition temperature Tc is traced over a range 0.26≤T/Tc≤0.95. This is represented by a number of relevant parameters such as the vortex transport entropy related to the Nernst-type effect at low T and a nonequilibrium magnetization enhancement close to Tc. At intermediate T, the Larkin-Ovchinnikov effect is at high currents modified by electron heating, which is clearly observed only in the TFTE.

description: Molecular dynamics simulations are used to study the phase behavior of a single linear multiblock copolymer with blocks of A- and B-type monomers under poor solvent conditions, varying the block length $N$, number of blocks $n$, and the solvent quality (by variation of the temperature $T$). The fraction $f$ of A-type monomers is kept constant and equal to 0.5, and always the lengths of A and B blocks were equal ($N_{A}=N_{B}=N$), as well as the number of blocks ($n_{A}=n_{B}=n$). We identify the three following regimes where: (i) full microphase separation between blocks of different type occurs (all blocks of A-type monomers form a single cluster, while all blocks of B-type monomers form another), (ii) full microphase separation is observed with a certain probability, and (iii) full microphase separation can not take place. For very high number of blocks $n$ and very high $N$ (not accessible to our simulations) further investigation is needed.

description: The high-mass microquasar Cygnus X-1, the best-established candidate for a stellar-mass black hole in the Galaxy, has been detected in a flaring state at very high energies (VHE), E > 200 GeV, by the Atmospheric Cherenkov Telescope MAGIC. The flare occurred at orbital phase 0.91, where phase 1 is the configuration with the black hole behind the companion high-mass star, when the absorption of gamma-ray photons by photon-photon annihilation with the stellar field is expected to be highest. We aim to set up a model for the high-energy emission and absorption in Cyg X-1 that can explain the nature of the observed gamma-ray flare. We study the gamma-ray opacity due to pair creation along the whole orbit, and for different locations of the emitter. Then we consider a possible mechanism for the production of the VHE emission. We present detailed calculations of the gamma-ray opacity and infer from these calculations the distance from the black hole where the emitting region was located. We suggest that the flare was the result of a jet-clump interaction where the decay products of inelastic proton-proton collisions dominate the VHE outcome. We are able to reproduce the spectrum of Cyg X-1 during the observed flare under reasonable assumptions. The flare may be the first event of jet-cloud interaction ever detected at such high energies.

description: We investigate a family of Hopf algebras of dimension 72 whose coradical is isomorphic to the algebra of functions on S_3. We determine the lattice of submodules of the so-called Verma modules and as a consequence we classify all simple modules. We show that these Hopf algebras are unimodular (as well as their duals) but not quasitriangular; also, they are cocycle deformations of each other.
