description: A high demand for woodchips has encouraged smallholder farmers in Vietnam to invest in short-rotation Acacia plantations to produce pulpwood that has a relatively quick, though often low, income return. Because of an expanding export furniture industry, the Vietnam Government has sought to increase sawlog production and, at the same time, improve returns to smallholder farmers. However, currently the quality and therefore market value of the timber from acacias under differing management strategies has not been well quantified. Acacia auriculiformis, both in its pure form and its hybrid with A. mangium (Acacia hybrid) are grown in plantations in Vietnam to produce merchantable timber, though the inferior mechanical properties of juvenile wood at an early age has impeded access to higher-value product markets. However, with thinning, there may be improvements in wood properties that could enhance sawlog values. This study examined how the wood properties of plantation grown Acacia hybrid change with stand age, explored differences in wood properties between Acacia hybrid and A. auriculiformis following different thinning treatments, and determined which of the two species is the most favourable for solid wood products. The potential to supply logs to produce sliced veneer for the furniture industry was also investigated. Logs from A. hybrid trees aged eight years could be processed to manufacture structural products, and at age five years for manufacturing utility furniture. Acacia auriculiformis thinned to 833 stems per hectare at age 4 years had mechanical wood properties indicating a potential for durable flooring products that can command a high value in the market. Because of dead knots, most sliced veneer samples were not acceptable for face veneer, though visual assessments indicated that with pruning, an attractive high-value product could potentially be produced. Tree species rather than age or thinning treatment had the most influence on wood properties.
Spin squeezing and precision probing with light and samples of atoms in the gaussian approximation

description: We consider an ensemble of trapped atoms interacting with a continuous wave laser field. For sufficiently polarized atoms and for a polarized light field, we may approximate the non-classical components of the collective spin angular momentum operator for the atoms and the Stokes vectors of the field by effective position and momentum variables for which we assume a gaussian state. Within this approximation, we present a theory for the squeezing of the atomic spin by polarization rotation measurements on the probe light. We derive analytical expressions for the squeezing with and without inclusion of the noise effects introduced by atomic decay and by photon absorption. The theory is readily adapted to the case of inhomogeneous light-atom coupling [A. Kuzmich and T.A.B. Kennedy, Phys. Rev. Lett. Vol. 92, 030407 (2004)]. As a special case, we show how to formulate the theory for an optically thick sample by slicing the gas into pieces each having only small photon absorption probability. Our analysis of a realistic probing and measurement scheme shows that it is the maximally squeezed component of the atomic gas that determines the accuracy of the measurement.

Chiral Limit of Strongly Coupled Lattice Gauge Theories

description: We construct a new and efficient cluster algorithm for updating strongly coupled U(N) lattice gauge theories with staggered fermions in the chiral limit. The algorithm uses the constrained monomer-dimer representation of the theory and should also be of interest to researchers working on other models with similar constraints. Using the new algorithm we address questions related to the chiral limit of strongly coupled U(N) gauge theories beyond the mean field approximation. We show that the infinite volume chiral condensate is non-zero in three and four dimensions. However, on a square lattice of size $L$ we find $\sum_x < \barψψ(x) \barψψ(0) > \sim L^{2-η}$ for large $L$ where $η= 0.420(3)/N + 0.078(4)/N^2$. These results differ from an earlier conclusion obtained using a different algorithm. Here we argue that the earlier calculations were misleading due to uncontrolled autocorrelation times encountered by the previous algorithm.

title: Woodrow Wilson and the American labour movement
Creators: name: Theakston, Colin
Publisher: name: The Open University
Year: 1992

description: This thesis examines President Woodrow Wilson’s relationship with the American labour movement, both the politically moderate American Federation of Labour (AFL) and the more radical Industrial Workers of the World (IWW). This thesis will attempt to show that contrary to received wisdom the administration of Woodrow Wilson was not in fact a golden age for the American labour movement. The thesis will demonstrate how the reforms granted during this period which aided labour were frequently passed over Wilson’s opposition or with nothing more than his passive support. It will also be shown that when Wilson cooperated with the AFL during the war, with places in the enlarged administration and with pressure on employers to make pro-labour concessions that it was only done for purely short-term reasons, to ensure labour cooperation - and that once the war had ended he withdrew that support. This thesis will also show how the suppression of the IWW during the war was not solely the product of that emergency, but that the desire to do so actually preceded the beginning of the conflict. These conclusions have been reached after studying President Wilson’s collected papers and the views of many of his contemporaries, and having read all the accepted leading secondary sources covering the period in question.

description: To integrate plasmonic devices into industry, it is essential to develop scalable and CMOS compatible plasmonic materials. In this work, we report high plasmonic quality titanium nitride (TiN) on c-plane sapphire by plasma enhanced atomic layer deposition (PE-ALD). TiN with low losses and high metallicity was achieved at temperatures below 500°C, by exploring the effects of chemisorption time, substrate temperature and plasma exposure time on material properties. Reduction in chemisorption time mitigates premature precursor decomposition at T_S > 375°C , and a trade-off between reduced impurity concentration and structural degradation caused by plasma bombardment is achieved for 25s plasma exposure. 85 nm thick TiN films grown at a substrate temperature of 450°C, compatible with CMOS processes, with 0.5s chemisorption time and 25s plasma exposure exhibited a high plasmonic figure of merit (|ε^'/ε^''|) of 2.8 and resistivity of 31 μΩ-cm. These TiN thin films fabricated with subwavelength apertures were shown to exhibit extraordinary transmission.

title: An assessment of the progress of tidal power within the UK
Creators: name: Watson, Walter
Publisher: name: The Open University
Year: 1993

description: The exploitation, for useful work, of the energy released by the rise and fall of the tides is not a new phenomenon. History records the existence of tide mills, particularly in England and France, many centuries ago. The conversion of the diurnal movement of the tides into electrical energy by the construction of barrages is, however, comparatively new, the first hard evidence of the technology appearing in the literature some seventy years ago. England, particularly the west coast of the country, has been identified as having very considerable tidal resources and this thesis reviews in detail the several tidal barrage schemes which have been proposed for a number of estuaries, including the Severn and the Mersey. The successful construction in the 1960’s of the 240MW tidal generation scheme on the Rance River in Northern France could perhaps have been expected to provide the impetus required for a tidal project to be agreed in this country. It remains a fact, however, that despite the information available from the successful implementation of the Rance scheme, the succession of Symposia held on the subject, the conclusions drawn by expert Committees, the research and development undertaken by specialist Companies, together with calls for action, no electricity generating barrage has been constructed, or even authorised, in this country. This thesis places on record the results of a detailed review of the extensive literature which now exists on the subject of tidal power. While so doing, it also attempts to provide insights into possible reasons why, despite environmental pressure for the control and reduction of emissions from fossil-fired power stations and public aversion to nuclear generated electricity, this country’s significant tidal resource of renewable green energy has not so far been tapped for electricity generation purposes.

description: This paper introduces an R package ForecastTB that can be used to compare the accuracy of different forecasting methods as related to the characteristics of a time series dataset. The ForecastTB is a plug-and-play structured module, and several forecasting methods can be included with simple instructions. The proposed test-bench is not limited to the default forecasting and error metric functions, and users are able to append, remove, or choose the desired methods as per requirements. Besides, several plotting functions and statistical performance metrics are provided to visualize the comparative performance and accuracy of different forecasting methods. Furthermore, this paper presents real application examples with natural time series datasets (i.e., wind speed and solar radiation) to exhibit the features of the ForecastTB package to evaluate forecasting comparison analysis as affected by the characteristics of a dataset. Modeling results indicated the applicability and robustness of the proposed R package ForecastTB for time series forecasting.

Thermodynamic instabilities in one dimensional particle lattices: a finite-size scaling approach
Creators: name: Theodorakopoulos, Nikos
Publisher: name: arXiv
Year: 2003
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: One-dimensional thermodynamic instabilities are phase transitions not prohibited by Landau's argument, because the energy of the domain wall (DW) which separates the two phases is infinite. Whether they actually occur in a given system of particles must be demonstrated on a case-by-case basis by examining the (non-) analyticity properties of the corresponding transfer integral (TI) equation. The present note deals with the generic Peyrard-Bishop model of DNA denaturation. In the absence of exact statements about the spectrum of the singular TI equation, I use Gauss-Hermite quadratures to achieve a single-parameter-controlled approach to rounding effects; this allows me to employ finite-size scaling concepts in order to demonstrate that a phase transition occurs and to derive the critical exponents.

Fermion Masses and Flavor Mixing in A Supersymmetric SO(10) Model

Publisher: name: arXiv
Year: 2004
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: we study fermion masses and flavor mixing in a supersymmetric SO(10) model, where $\mathbf{10}$, $\mathbf{120}$ and $\mathbf{\bar{126}}$ Higgs multiplets have Yukawa couplings with matter multiplets and give masses to quarks and leptons through the breaking chain of a Pati-Salam group. This brings about that, at the GUT energy scale, the lepton mass matrices are related to the quark ones via several breaking parameters, and the small neutrino masses arise from a Type II see-saw mechanism. When evolving renormalization group equations for the fermion mass matrices from the GUT scale to the electroweak scale, in a specific parameter scenario, we show that the model can elegantly accommodate all observed values of masses and mixing for the quarks and leptons, especially, it's predictions for the bi-large mixing in the leptonic sector are very well in agreement with the current neutrino experimental data.

Navigating liminal space : my journey towards becoming a home economics teacher
Creators: name: Dyck, Rosie Angeline
Publisher: name: The University of British Columbia
Year: 2023

description: This self-study is an exploration of my personal journey through liminal space towards becoming a home economics teacher. I explore how my understanding of curriculum and pedagogy has evolved throughout this process. My research is situated in the interpretivist paradigm, incorporating the methodologies of self-study, narrative inquiry, and a/r/tography. My research puzzle is:  In what ways has my experience of liminal space shaped my understanding of curriculum and pedagogy (in general, and specifically in home economics)? My focus is on the educational significance of liminal space, looking beyond the visible transitions between studenthood (Field, 2012) and professional life. I examine threshold concepts, which “represent a transformed way of understanding, or interpreting, or viewing something without which the learner cannot progress” (Meyer & Land, 2003, p. 1), including what I believe to be threshold concepts of home economics education: everyday life, ecological perspective, interdisciplinarity, and community. Besides helping myself to navigate the idea of home economics in an elementary classroom, my journey through liminal space may help others who are trying to teach home economics in various subject areas, including experienced teachers making mid-career moves to new teaching areas. Since home economics education programs are being cut at the university level, and home economics is not explicitly taught at many schools, there is a need to examine how home economics can be taught throughout the curriculum.

description: Optomechanical systems offer new opportunities in quantum information processing and quantum sensing. Many solid-state quantum devices operate at millikelvin temperatures -- however, it has proven challenging to operate nanoscale optomechanical devices at these ultralow temperatures due to their limited thermal conductance and parasitic optical absorption. Here, we demonstrate a two-dimensional optomechanical crystal resonator capable of achieving large cooperativity $C$ and small effective bath occupancy $n_b$, resulting in a quantum cooperativity $C_{\text{eff}}\equiv C/n_b \approx 1.3 > 1$ under continuous-wave optical driving. This is realized using a two-dimensional phononic bandgap structure to host the optomechanical cavity, simultaneously isolating the acoustic mode of interest in the bandgap while allowing heat to be removed by phonon modes outside of the bandgap. This achievement paves the way for a variety of applications requiring quantum-coherent optomechanical interactions, such as transducers capable of bi-directional conversion of quantum states between microwave frequency superconducting quantum circuits and optical photons in a fiber optic network.

description: The problem of description of superintegrable systems (i.e., systems with closed trajectories in a certain domain) in the class of rotationally symmetric natural mechanical systems goes back to Bertrand and Darboux. We describe all superintegrable (in a domain of slow motions) systems in the class of rotationally symmetric magnetic geodesic flows. We show that all sufficiently slow motions in a central magnetic field on a two-dimensional manifold of revolution are periodic if and only if the metric has a constant scalar curvature and the magnetic field is homogeneous, i.e. proportional to the area form.

description: Instability in interest rate policy created interest rate volatility. The study investigated the relationship between the value of guaranteed loans and interest rate policy on the growth of Agricultural Credit Guarantee Scheme activities in Nigeria. Time series data collected from the staiistical bulletin of Central Bank of Nigeria were used for the analysis. Multiple regression models were used in estimating the effects of interest rate policy on the value of loans/advances accessed by agro-entrepreneurs under ACGS over the years. The results showed that value of loans/advances accessed by the loan beneficiaries under ACGS was inversely related to interest rate policy and directly influenced by outreach, loan repayment and liquidity over the years. It is recommended that incentive be created in form of increased rate for interest drawback scheme. This would assist to rebate high lending rates by the banking system

Creators: name: Dooley, Brian
Publisher: name: The Open University
Year: 1993

description: This study traces Kennedy's political development from his election to the Senate in 1964 to his death in 1968. During that time, he transformed from a hesitant and orthodox liberal to spearhead a new radicalism and develop an alternative coalition for the Democratic Party. In the domestic arena, he proposed an alternative approach for urban renewal, and became remarkably popular with black voters (even more popular than has previously been accepted). This study attempts to fathom the full extent of this relationship and how powerful it could have become. Kennedy was also among the first politicians of his generation to use the political muscle of the youth groups which were springing up in the mid-'60s, and the alternative labour organisations (most notably in California) which found themselves excluded from the old union power structures. The study also charts his rise in the anti-Vietnam war movement, and questions his reputation as a hard-line anti­ communist which emerged during the Kennedy administration. It examines his presidential campaign in the context of his alternative liberal coalition, and an analysis of his primary results suggests that the accepted wisdom of a Kennedy poverty coalition (made up of low-income black and white voters) is largely mythological. Finally, the study offers some tentative conclusions about the real nature of Kennedy's contribution to modern liberalism, and a brief historiography.

This technique allows one to achieve a good binary detection and therefore measure switching probabilities. The technique overcomes limitations on simple square pulses and allows for the measurement of junctions with critical currents of the order of 10nA with bias pulses of the order of 100ns. A correlation analysis of the switching events is performed to show how the switching probability depends on the wait time between repeated bias pulses.

The surface morphology obtained by atomic force microscopy (AFM) and cross-sectional transmission electron microscopy images (TEM) shows that the Ge islands are preferentially grown at the sidewalls of pure Si stripes along [-110] direction at 650o C or along the trenches, whereas most of the Ge islands are formed on the top terrace when the patterned stripes are covered by a strained GeSi buffer layer. Reducing the growth temperature to 600oC results in a nucleation of Ge islands both on the top terrace and at the sidewall of pure Si stripes. A qualitative analysis, based on the growth kinetics, demonstrates that the step structure of the stripes, the external strain field and the local critical wetting layer thickness for the islands formation contribute to the preferential positioning of Ge islands on the stripes.

description: We calculate exactly the probability to find the ground state of the XY chain in a given spin configuration in the transverse $σ^z$-basis. By determining finite-volume corrections to the probabilities for a wide variety of configurations, we obtain the universal Boundary Entropy at the critical point. The latter is a benchmark of the underlying Boundary Conformal Field Theory characterizing each quantum state. To determine the scaling of the probabilities, we prove a theorem that expresses, in a factorized form, the eigenvalues of a sub-matrix of a circulant matrix as functions of the eigenvalues of the original matrix. Finally, the Boundary Entropies are computed by exploiting a generalization of the Euler-MacLaurin formula to non-differentiable functions. It is shown that, in some cases, the spin configuration can flow to a linear superposition of Cardy states. Our methods and tools are rather generic and can be applied to all the periodic quantum chains which map to free-fermionic Hamiltonians.

description: Many researchers work on improving the data efficiency of machine learning. What would happen if they succeed? This paper explores the social-economic impact of increased data efficiency. Specifically, we examine the intuition that data efficiency will erode the barriers to entry protecting incumbent data-rich AI firms, exposing them to more competition from data-poor firms. We find that this intuition is only partially correct: data efficiency makes it easier to create ML applications, but large AI firms may have more to gain from higher performing AI systems. Further, we find that the effect on privacy, data markets, robustness, and misuse are complex. For example, while it seems intuitive that misuse risk would increase along with data efficiency -- as more actors gain access to any level of capability -- the net effect crucially depends on how much defensive measures are improved. More investigation into data efficiency, as well as research into the "AI production function", will be key to understanding the development of the AI industry and its societal impacts.

Spin-Charge Separation and Kinetic Energy in the t-J Model

description: I show that spin-charge separation in 2-D t-J model leads to an increase of kinetic energy. Using a sum rule, I derive an exact expression for the lowest possible KE (E_{bound}) for any state without doubly occupied sites. KE of relevant slave-boson and Schwinger-boson mean-field states -- which exhibit complete spin-charge separation -- are found to be much larger than E_{bound}. Examination of n(k) shows that the large increse in KE is due to excessive depletion of electrons from the bottom of the band (Schwinger boson) and of holes from the top (slave boson). To see whether the excess KE is simply due to poor treatment of the constraints, I solve the constraint problem analytically for the Schwinger boson case in the J = 0 limit. This restores gauge invariance, incorrectly violated in MF theories. The result is a generalized Hartree-Fock state of the Hubbard model, but one that includes spin waves. Even after constraints are imposed correctly, the KE remains much larger than E_{bound}. These results support the notion, advanced earlier [PRB 61, 8663 (2000)] that spin-charge separation in the MF state costs excessive KE, and makes the state unstable toward recombination processes which lead to superconductivity in d = 2 and a Fermi liquid state in higher dimensions.

description: This study analysed rice importation trend in Nigeria and its effect on local production from 1970 - 2013. Data were collected from secondary sources only. The study used annual time series data on quantity of locally produced rice, quantity of imported rice, rice yield and rice consumption. The ordinary least square (OLS) regression technique was employed for data analysis. Augmented Dickey Fuller test) as used to check for stationarity of the variables. The line graph was used to check for the pattern of growth on each of the variables, while the semi log growth model was used to check for the quantitative growths presented as instantaneous and cumulative growth in the various variables). The results of the study revealed that: instantaneous growth in local rice production stood at 5. 7%, cumulative growth 5.9%, while rice importation was 12.3% and 12.7% respectively. This implies a faster rate of growth for rice production than importation. Rice yield had an instantaneous growth of -0.15% and cumulative growth -0.14%, while rice consumption was 6.58% and 6.8% respectively, implying a decline in rice yield which was not commensurate with the growth in rice consumption. Increasing the quantity of Nigerian rice production thr~ugh improving Nigerian rice yield to cushion the expected Nigerian rice consumption forecast will be beneficial to the Nigerian economy than importation of foreign rice which will deplete the nation's foreign reserve.

description: Within the effective interfacial Hamiltonian approach we evaluate the excess line free energy associated with cylinder-shaped droplets sessile on a stripe-like chemical inhomogeneity of a planar substrate. In the case of short-range intermolecular forces the droplet morphology and the corresponding expression for the line tension - which includes the inhomogeneity finite width effects - are derived and discussed as functions of temperature and increasing width. The width-dependent contributions to the line tension change their structure at the stripe wetting temperature T_W1: for TT_W1 the decay is algebraic. In addition, a geometric construction of the corresponding contact angle is carried out and its implications are discussed.

description: The Andreev reflection measurements of the superconducting energy gap in the carbon-substituted MgB$_2$ are presented. Despite the strong suppression of the transition temperature by 17 K in comparison with the pure MgB$_2$, the same reduced value of the small superconducting energy gap with $2Δ/kT_c \approx$ 1.7 has been systematically observed. This indicates that the two band/two gap superconductivity is still preserved here.

description: Heaps are para-associative ternary operations bijectively exemplified by groups via the operation $(x,y,z) \mapsto x y^{-1} z$. They are also ternary self-distributive, and have a diagrammatic interpretation in terms of framed links. Motivated by these properties, we define para-associative and heap cohomology theories and also a ternary self-distributive cohomology theory with abelian heap coefficients. We show that one of the heap cohomologies is related to group cohomology via a long exact sequence. Moreover we construct maps between second cohomology groups of normalized group cohomology and heap cohomology, and show that the latter injects into the ternary self-distributive second cohomology group. We proceed to study heap objects in symmetric monoidal categories providing a characterization of pointed heaps as involutory Hopf monoids in the given category. Finally we prove that heap objects are also "categorically" self-distributive in an appropriate sense.

Teaching Aboriginal education : responding to the Truth and Reconciliation Commission's calls to action for early childhood classrooms
Creators: name: Desjardins, Danielle
Publisher: name: The University of British Columbia
Year: 2018

description: In response to the Truth and Reconciliation Commission (2015) Calls to Action, my capstone project explores ways in which to implement Aboriginal pedagogy in early childhood programs (Pre K-K) in the province of Saskatchewan, Canada. Grounded within socio-cultural theory, I focus on four aspects of Aboriginal pedagogy: relationships with family and community, experiential learning, storytelling, and relationship with the land. From the literature reviewed and the resources gathered, I found that implementing Aboriginal pedagogy, connected with place-based education and Social and Emotional Learning (SEL) into early childhood classrooms enhances children’s understanding of the cultural context, and strengthens their relationship with, the place in which they live. In connecting this research to practice, I included my own experiences as a parent and a teacher, as well as draw from examples of early childhood educators who are currently incorporating Aboriginal pedagogy, history, and culture into their programs. As an outcome of this project, I developed a website that is focused on implementing Aboriginal pedagogy in early childhood (Pre K - K) in Saskatchewan in order to support educators, and as a response to the TRC’s (2015) Call to Action in education to share lesson plans and best practices. Based on the findings from the literature reviewed, I recommend pre-service and in-service education on Aboriginal pedagogy, culture, and history, with a focus on place-based education, and building children’s capacity for empathy to support both Aboriginal and non-Aboriginal young learners.
