Subjects: Public Economics

description: The main purpose of this paper is to discuss aspects of taxation policy as it is applied to rural sector issues. The paper begins by reviewing the relevance of rural income volatility, and general trends in protection policy, for taxation policy design. Comments are included on the general appropriateness of concessional tax treatment and a description is provided of key taxation policy principles - equity, efficiency, certainty and administrability. The paper then illustrates how these taxation policy principles are taken into account during the policy advising process. Four case studies are used for this purpose: drought, water reform, horticulture and landcare.

description: We study the implications of the anyon fusion equation $a\times b=c$ on global properties of $2+1$D topological quantum field theories (TQFTs). Here $a$ and $b$ are anyons that fuse together to give a unique anyon, $c$. As is well known, when at least one of $a$ and $b$ is abelian, such equations describe aspects of the one-form symmetry of the theory. When $a$ and $b$ are non-abelian, the most obvious way such fusions arise is when a TQFT can be resolved into a product of TQFTs with trivial mutual braiding, and $a$ and $b$ lie in separate factors. More generally, we argue that the appearance of such fusions for non-abelian $a$ and $b$ can also be an indication of zero-form symmetries in a TQFT, of what we term "quasi-zero-form symmetries" (as in the case of discrete gauge theories based on the largest Mathieu group, $M_{24}$), or of the existence of non-modular fusion subcategories. We study these ideas in a variety of TQFT settings from (twisted and untwisted) discrete gauge theories to Chern-Simons theories based on continuous gauge groups and related cosets. Along the way, we prove various useful theorems.

description: We derive the $l_{\infty}$ convergence rate simultaneously for Lasso and Dantzig estimators in a high-dimensional linear regression model under a mutual coherence assumption on the Gram matrix of the design and two different assumptions on the noise: Gaussian noise and general noise with finite variance. Then we prove that simultaneously the thresholded Lasso and Dantzig estimators with a proper choice of the threshold enjoy a sign concentration property provided that the non-zero components of the target vector are not too small.

description: It is widely accepted that accelerated depreciation concessions, such as sections 75B and 750, are a poor means for government to address environmental objectives. This position is further supported by recent information highlighting the limited behavioural effect of this form of intervention. The continued existence of poorly targeted subsidy measures, in the face of mounting evidence of their ineffectual nature, suggests they are an important source of political benefits. It is further proposed that as assistance to agriculture declines, the political value of 'generic' policies providing economic rents to industry, such as taxation concessions, will increase and potentially impede the development of agricultural-environmental policy. The further point made is that significant environmental gains will be associated with a greater degree of policy complementarity, not only among elements of the Income Tax Assessment Act 1936, but among elements of rural policy generally.

description: Accelerated depreciation and investment allowances are frequently requested by industry as a means of encouraging investment and promoting the adoption of socially desirable practices by farmers. Examples include the 100 per cent tax deduction for capital expenditure to combat and prevent land degradation (Section 750), and the recently introduced 10 per cent investment allowance for fodder and water storage for livestock, water conveyancing and minimum tillage equipment. Farm level survey data are used to provide evidence of the extent and distribution of benefits to farmers that flow from different rates of depreciation, and from the introduction of a 10 per cent investment allowance. A priori, it may be difficult for the farmer (or farm financial adviser) to determine which depreciation period will provide the largest tax benefit, as the results are dependent on both future taxable incomes, and tax rates.

description: Globular clusters have long been known for presenting (at times) significant deviations from spherical symmetry. While rotation has been the main proposed explanation, other complicating factors such as their constant interaction with the strong gravitational potential of their host galaxy have made it difficult for a consensus to be reached. To address this question we have obtained high-resolution spectra of WLM-1, the lone globular cluster associated with the isolated, low-mass dwarf irregular galaxy WLM. Using archival HST WFPC2 data, we measure the radial ellipticity profile of WLM-1, finding it to be highly elliptical, with a mean value of 0.17 in the region 0.5-5" -- which is comparable to what is found in our Galaxy for the most elliptical globular clusters. There is no evidence of isophote twisting, except for the innermost regions of the cluster (r < 0.5"). To investigate whether the observed flattening can be ascribed to rotation, we have obtained long-slit high-resolution VLT/UVES spectra of this cluster along and perpendicular to the axis of flattening. Using cross-correlation we find that the velocity profile of the cluster is consistent with zero rotation along either axis. Thus neither cluster rotation nor galactic tides can be responsible for the flattened morphology of WLM-1. We argue that the required velocity dispersion anisotropy between the semi-major and semi-minor axes that would be required to account for the observed flattening is relatively small, of order 1 km/s. Even though our errors preclude us from conclusively establishing that such a difference indeed exists, velocity anisotropy remains at present the most plausible explanation for the shape of this cluster.

description: L’objet de notre article est la phase de co-situation d’une recherche collaborative, selon des modalités en partie à distance et en présentiel, entre la Guyane française (terrain de recherche) et la Suisse (université de la chercheuse concernée). Plus particulièrement, l’article investigue les défis et les obstacles intervenants lors de la co-élaboration d’un dispositif impliquant une chercheuse doctorante et des enseignantes éloignées par la distance géographique. Ce dispositif d’évaluation formative du langage oral d’élèves allophones de maternelle (4-5 ans) se déroule dans un contexte où opère le translanguaging (alternance de langues) entre les enseignantes (français) et les élèves (n’djuka). À partir d’entretiens exploratoires, individuels et collectifs, une dynamique atypique est dégagée dans la négociation de la problématique commune qui s’étend sur toute la phase de co-situation de la recherche. Cinq axes ont été identifiés, regroupant des obstacles et des défis interdépendants que sont (1) l’initiation de la co-situation, (2) l’opérationnalisation d’un tiers-espace physique et temporel, (3) la construction et le maintien d’un climat de confiance mutuelle, (4) la co-construction et le partage d’une problématique commune et (5) l’opérationnalisation sur le plan méthodologique. D’autres éléments montrent que, de prime abord, ce qui pouvait constituer des obstacles et des défis spécifiques à l’éloignement géographique peut, in fine, être des ressources pour la co-construction de l’objet.

description: Tax subsidies are an often overlooked method by which government subsidises agriculture. An examination of tax policies in Australia, Canada, Germany and the United States reveals several different tax subsidies provided to farmers in these countries. Most of these subsidies are in theory subject to reduction under GATT. For various reasons, however, most tax subsidies are not included in subsidy measures. Failure to include these kinds of subsidies in AMS measures could encourage their proliferation among countries desiring to continue agricultural subsidies.

description: Suppose that there are n bins, and balls arrive in a Poisson process at rate λn, where λ>0 is a constant. Upon arrival, each ball chooses a fixed number d of random bins, and is placed into one with least load. Balls have independent exponential lifetimes with unit mean. We show that the system converges rapidly to its equilibrium distribution; and when d\geq 2, there is an integer-valued function m_d(n)=\ln \ln n/\ln d+O(1) such that, in the equilibrium distribution, the maximum load of a bin is concentrated on the two values m_d(n) and m_d(n)-1, with probability tending to 1, as n\to \infty. We show also that the maximum load usually does not vary by more than a constant amount from \ln \ln n/\ln d, even over quite long periods of time.

description: In this paper, we introduce optimal versions of a multi-port based teleportation scheme allowing to send a large amount of quantum information. We fully characterise probabilistic and deterministic case by presenting expressions for the average probability of success and entanglement fidelity. In the probabilistic case, the final expression depends only on global parameters describing the problem, such as the number of ports $N$, the number of teleported systems $k$, and local dimension $d$. It allows us to show square improvement in the number of ports with respect to the non-optimal case. We also show that the number of teleported systems can grow when the number $N$ of ports increases as $o(N)$ still giving high efficiency. In the deterministic case, we connect entanglement fidelity with the maximal eigenvalue of a generalised teleportation matrix. In both cases the optimal set of measurements and the optimal state shared between sender and receiver is presented. All the results are obtained by formulating and solving primal and dual SDP problems, which due to existing symmetries can be solved analytically. We use extensively tools from representation theory and formulate new results that could be of the separate interest for the potential readers.

description: We put together the results of XMM-Newton observations of a number of representative group and cluster samples at low and high redshifts. These results confirm the entropy ramp as an explanation of the observed scaling relations. We observe a mild evolution in the entropy of clusters. The observed degree of evolution is consistent with expectations of the shock heating at a fixed overdensity (500) with respect to the critical density in LCDM. The study of the evolution in the pressure scaling imposes strong requirements in the definition of the average temperature of the cluster. The scaling temperature should be consistent to better than the 10% level. Once such a consistency is achieved, no additional evolution in the pressure has been detected in addition to the prediction of the shock heating in the LCDM Universe.

description: We derive an effective dissipative quantum field theory for fluctuating orbital currents in clean $CuO_2$ sheets of high-$T_c$ cuprates, based on a three-band model. The Coulomb repulsion term between $Cu$- and $O$-sites is decoupled in terms of current operators representing horizontal and vertical parts of circulating currents within each $CuO_2$ unit cell of the lattice. The model has ordering of currents at finite temperatures. The dissipative kernel in the model is of the form $|ω|/|{\bf q}|$, indicating Landau damping. Applications of the effective theory to other models are also discussed.

description: The exponential growth in Hilbert space with increasing size of a quantum system means that accurately characterising the system becomes significantly harder with system dimension d. We show that self-guided tomography is a practical, efficient, and robust technique of measuring higher-dimensional quantum states. The achieved fidelities are over 99.9% for qutrits (d=3) and ququints (d=5), and 99.1% for quvigints (d=20), the highest values ever realised for qudits. We demonstrate robustness against experimental sources of noise, both statistical and environmental. The technique is applicable to any higher-dimensional system, from a collection of qubits through to individual qudits, and any physical realisation, be it photonic, superconducting, ionic, or spin.

Assessing discrimination in a police recruit assessment center

Publisher: name: University of British Columbia
Year: 2009

description: The overall concern of this study is that of substantive equality, as defined by Canadian law, in the employment context, and the specific goal of this study is to provide a model to assess (and prevent) unlawful systemic discrimination in an assessment center. Because discrimination is essentially the same, wherever it occurs, the model proposed in this study is also useful for assessing discrimination in employment selection generally. In the employment context, evidence of systemic discrimination is often limited to selection patterns, and so this study argues that statistical analyses can be particularly useful. Since the Supreme Court adopted the effects theory, where intent is immaterial and the focus is on results, such analyses are likely to become an appealing alternative to traditional arguments of exclusion and disproportion. The analytic model proposed here suggests two general phases to a legal analysis of discrimination. First, there is the preliminary phase, which consists of three interrelated steps: identifying the applicable selection procedure, identifying the relevant legal issue, and identifying the appropriate groups for comparison. Second, there is the assessment phase, which consists of two sequential steps: comparing the groups of interest on the dimension of interest to determine if differences exist, and analyzing observed differences to determine if they are legally or practically significant. It is in this phase that statistical analyses can be especially helpful in an assessment of systemic discrimination. To test its utility, the proposed model was applied to the Justice Institute of British Columbia Police Academy assessment center (where entry level police applicants are screened) to determine whether the assessment center discriminated on the basis of sex. Of particular interest to the Police Academy is that the results indicated no sex discrimination, but notably the results also indicated that the proposed model provides a practicable and relatively uncomplicated way to assess discrimination. Moreover, consistent with the goal of prevention, this study demonstrates how a reliability assessment can provide important information about the potential for discrimination in employee selection, thereby providing employers with the means to be more proactive than otherwise possible.

description: The aim of the work was to explore the practical applicability of molecular dynamics at different length and time scales. From nanoparticles system over colloids and polymers to biological systems like membranes and finally living cells, a broad range of materials was considered from a theoretical standpoint. In this dissertation five chemistry-related problem are addressed by means of theoretical and computational methods. The main results can be outlined as follows.
(1) A systematic study of the effect of the concentration, chain length, and charge of surfactants on fullerene aggregation is presented. The long-discussed problem of the location of C60 in micelles was addressed and fullerenes were found in the hydrophobic region of the micelles. 
(2) The interactions between graphene sheet of increasing size and phospholipid membrane are quantitatively investigated. 
(3) A model was proposed to study structure, stability, and dynamics of MoS2, a material well-known for its tribological properties. The telescopic movement of nested nanotubes and the sliding of MoS2 layers is simulated.
(4) A mathematical model to gain understaning of the coupled diffusion-swelling process in poly(lactic-co-glycolic acid), PLGA, was proposed.
(5) A soft matter cell model is developed to explore the interaction of living cell with artificial surfaces. The effect of the surface properties on the adhesion dynamics of cells are discussed.

description: Several general trends have been identified for equilibrated, self-gravitating collisionless systems, such as density or anisotropy profiles. These are integrated quantities which naturally depend on the underlying velocity distribution function (VDF) of the system. We study this VDF through a set of numerical simulations, which allow us to extract both the radial and the tangential VDF. We find that the shape of the VDF is universal, in the sense that it depends only on two things namely the dispersion (radial or tangential) and the local slope of the density. Both the radial and the tangential VDF's are universal for a collection of simulations, including controlled collisions with very different initial conditions, radial infall simulation, and structures formed in cosmological simulations.

description: Two-dimensional QCD has often been used as a laboratory for studying the full four-dimensional theory, providing, for example, an explicit realization of baryons as solitons. We review aspects of conventional baryons in two-dimensional QCD, including the classical and quantum contributions to their masses. We then discuss the spectrum of exotic baryons in two-dimensional QCD, commenting on the solitonic radius inferred from the excitation spectrum as well as the two-dimensional version of the Goldberger-Treiman relation relating meson couplings to current matrix elements. Two-dimensional QCD provides strong overall support to the chiral-soliton picture for the structure of normal and exotic baryons in four dimensions.

description: We quantify the calibration requirements for systematic uncertainties for next-generation ground-based observatories targeting the large-angle $B$-mode polarization of the Cosmic Microwave Background, with a focus on the Simons Observatory (SO). We explore uncertainties on gain calibration, bandpass center frequencies, and polarization angles, including the frequency variation of the latter across the bandpass. We find that gain calibration and bandpass center frequencies must be known to percent levels or less to avoid biases on the tensor-to-scalar ratio $r$ on the order of $Δr\sim10^{-3}$, in line with previous findings. Polarization angles must be calibrated to the level of a few tenths of a degree, while their frequency variation between the edges of the band must be known to ${\cal O}(10)$ degrees. Given the tightness of these calibration requirements, we explore the level to which residual uncertainties on these systematics would affect the final constraints on $r$ if included in the data model and marginalized over. We find that the additional parameter freedom does not degrade the final constraints on $r$ significantly, broadening the error bar by ${\cal O}(10\%)$ at most. We validate these results by reanalyzing the latest publicly available data from the BICEP2/Keck collaboration within an extended parameter space covering both cosmological, foreground and systematic parameters. Finally, our results are discussed in light of the instrument design and calibration studies carried out within SO.

description: We present the results of a novel application of Bayesian modelling techniques, which, although purely data driven, have a physically interpretable result, and will be useful as an efficient data mining tool. We base our studies on the UV-to-optical spectra (observed and synthetic) of early-type galaxies. A probabilistic latent variable architecture is formulated, and a rigorous Bayesian methodology is employed for solving the inverse modelling problem from the available data. A powerful aspect of our formalism is that it allows us to recover a limited fraction of missing data due to incomplete spectral coverage, as well as to handle observational errors in a principled way. We apply this method to a sample of 21 well-studied early-type spectra, with known star-formation histories. We find that our data-driven Bayesian modelling allows us to identify those early-types which contain a significant stellar population

description: This poster illustrates fire behaviour in blue gum (Eucalyptus globulus) plantations in Portugal under low-to-moderate fire danger as per the Canadian Forest Fire Weather (FWI) System. The observations result from an experimental burning program in 7 to 11-year-old stands carrying fuel loads of 10-15 t ha-1 and with minimum understorey cover (<20%).

Fires took place within 16 days after the last rainfall, with ambient temperature, relative humidity and 2-m wind speed inside the stand varying respectively from 9 to 21 ºC, 33 to 100%, and one to 11 km h-1. The minimum surface fine fuel moisture content was 11%. Each photo displays the six FWI indices for the day of the burn.
The mildest conditions corresponded to non-sustained (photo 1) or patchy (photos 2 and 3) fire spread, with rates of forward spread and flame length respectively <30 m h-1 and <0.2 m. Fire behaviour under the highest fire danger conditions observed (photos 5 and 6) was characterized by rates of spread <150 m h-1, flame lengths <1.2 m, near-total fuel consumption, and fireline intensities <500 kW m-1, all within the control capacity of hand crews.

Relationships between fire danger rating and actual fire behaviour can assist in planning prescribed burning operations in blue gum stands and are useful to define pre-suppression preparedness.

description: From treating DNA as letters, Genes as words and Proteins as sentences, we go on to decode the "grammar" (both 'intra-' and 'inter-') using QCA (Quarternary Cellular Automata) applying the "Principle of Computational Equivalence" between cDNA (4-nt) and protein (20-aa) sequences. Further, we do achieve a neat proof in the specific case of mtDNA using circular permutations and Lagrange series: both these approaches proving that cardinality of nt in Universal Genetic Codon is e= Napier's constant= 2.718... And additionally, the 2 Original concepts of "Super-reference genome" and "e-blastx" are duly presented.

description: The results from a Hubble Space Telescope (HST) snapshot survey of post-AGB objects are shown. The aim of the survey is to complement existing HST images of PPN and to connect various types of nebulosities with physical and chemical properties of their central stars. Nebulosities are detected in 15 of 33 sources. Images and photometric and geometric measurements are presented. For sources with nebulosities we see a morphological bifurcation into two groups, DUPLEX and SOLE, as previous studies have found. We find further support to the previous results suggesting that this dichotomy is caused by a difference in optical thickness of the dust shell. The remaining 18 sources are classified as stellar post-AGB objects, because our observations indicate a lack of nebulosity. We show that some stellar sources may in fact be DUPLEX or SOLE based on their infrared colors. The cause of the differences among the groups are investigated. We discuss some evidence suggesting that high progenitor-mass AGB stars tend to become DUPLEX post-AGB objects. Intermediate progenitor-mass AGB stars tend to be SOLE post-AGB objects. Most of the stellar sources probably have low mass progenitors and do not seem to develop nebulosities during the post-AGB phase and therefore do not become planetary nebulae.

Quantum effects from a purely geometrical relativity theory

description: A purely geometrical relativity theory results from a construction that produces from three-dimensional space a happy unification of Kaluza's five-dimensional theory and Weyl's conformal theory. The theory can provide geometrical explanations for the following observed phenomena, among others: (a) lifetimes of elementary particles of lengths inversely proportional to their rest masses; (b) the equality of charge magnitude among all charged particles interacting at an event; (c) the propensity of electrons in atoms to be seen in discretely spaced orbits; and (d) `quantum jumps' between those orbits. This suggests the possibility that the theory can provide a deterministic underpinning of quantum mechanics like that provided to thermodynamics by the molecular theory of gases.

description: While current monocular 3D face reconstruction methods can recover fine geometric details, they suffer several limitations. Some methods produce faces that cannot be realistically animated because they do not model how wrinkles vary with expression. Other methods are trained on high-quality face scans and do not generalize well to in-the-wild images. We present the first approach that regresses 3D face shape and animatable details that are specific to an individual but change with expression. Our model, DECA (Detailed Expression Capture and Animation), is trained to robustly produce a UV displacement map from a low-dimensional latent representation that consists of person-specific detail parameters and generic expression parameters, while a regressor is trained to predict detail, shape, albedo, expression, pose and illumination parameters from a single image. To enable this, we introduce a novel detail-consistency loss that disentangles person-specific details from expression-dependent wrinkles. This disentanglement allows us to synthesize realistic person-specific wrinkles by controlling expression parameters while keeping person-specific details unchanged. DECA is learned from in-the-wild images with no paired 3D supervision and achieves state-of-the-art shape reconstruction accuracy on two benchmarks. Qualitative results on in-the-wild data demonstrate DECA's robustness and its ability to disentangle identity- and expression-dependent details enabling animation of reconstructed faces. The model and code are publicly available at https://deca.is.tue.mpg.de.

description: Conditions for the existence and stability of de Sitter space in modified gravity are derived by considering inhomogeneous perturbations in a gauge-invariant formalism. The stability condition coincides with the corresponding condition for stability with respect to homogeneous perturbations, while this is not the case in scalar-tensor gravity. The stability criterion is applied to various modified gravity models of the early and the present universe.

description: We have performed de novo whole genome sequencing of three Saccharomyces cerevisiae strains using PacBio long-read sequencing. Preliminary comparative analysis of these genomes shows a number of translocations between chromosome ends in addition to one large rearrangement in MBG479 where the long arm of chromosome IX has translocated to chromosome VII due to presumed recombination at a Ty element. Long reads also enabled us to detect high mobility of the Ty elements between strains.

description: Traction or frictional resistance of tires on clean, dry pavements tends to be fairly high (coefficient of friction of 0.6 to 0.8) and to be independent of the texture of the pavement surface. In contrast, the loss of traction on a wet pavement is due entirely to lubrication effects; and, while wet friction seems to be fairly independent of the identity of the aggregate, it is extremely dependent upon the texture and porosity of the surface. Likewise, the mineralogical and lithological characteristics of the aggregates largely determine the natural texture, i.e., type of wear (coarse or fine) which the aggregate will undergo in roadway service (1).

description: We have investigated the properties of the diffuse light in the Virgo cluster core region, based on the detection of intracluster planetary nebulae (PNe) in four fields. We eliminate the bias from misclassified faint continuum objects, using improved Monte Carlo simulations, and the contaminations by high redshift Ly$α$ galaxies, using the Ly$α$ luminosity function in blank fields. Recent spectroscopic observations confirm that our photometric PN samples are well-understood. We find that the diffuse stellar population in the Virgo core region is inhomogeneous on scales of 30'-90': there exist significant field-to-field variations in the number density of PNe and the inferred amount of intracluster light, with some empty fields, some fields dominated by extended Virgo galaxy halos, and some fields dominated by the true intracluster component. There is no clear trend with distance from M87. The mean surface luminosity density, its rms variation, and the mean surface brightness of diffuse light in our 4 fields are $Σ_B = 2.7 x 10^{6}$ L$_{B\odot}$ arcmin$^{-2}$, ${rms} = 2.1 \times 10^{6}$ L$_{B\odot}$ arcmin$^{-2}$, and $\barμ_{B}=29.0$ mag arcsec$^{-2}$ respectively. Our results indicate that the Virgo cluster is a dynamically young environment, and that the intracluster component is associated at least partially with local physical processes like galaxy interactions or harassment. We also argue, based on kinematic evidence, that the so-called 'over-luminous' PNe in the halo of M84 are dynamically associated with this galaxy, and must thus be brighter than and part of a different stellar population from the normal PN population in elliptical galaxies.

Learning to leave : the irony of schooling in a coastal community
Creators: name: Corbett, Michael John
Publisher: name: University of British Columbia

description: The connection between education and migration from rural areas is one that has been made since Western democracies began keeping statistics. While there has been considerable work done on the migration experiences of rural Canadians, there has been little research done on how the educational experience of rural people actually figures in migration decisions and experience. Education is typically understood as a modernising and a disembedding force facilitating the transition of societies and individuals from rural to urban communities, but there is as yet, little evidence about how this process is understood and enacted by the people who experience the process. The study combines quantitaitve and qualitative methods to explore the both the broad contours and lived experience of the problem of learning and leaving in an Atlantic Canadian coastal community. The purpose of this work is to investigate the contours of the question: how do some young people in coastal communities come to learn, in the course of their schooling, that the places in which they have been raised are best abandoned and forgotten. In other words, how do many rural youth learn to leave? Conversely, the study also investigates the dynamics of the decision to stay on in the community and make a life there, foregoing, if not resisting formal education. The study is an investigation of educational and work history data from more than 750 individuals who left grade 6 in an elementary school serving nine fishing villages on Digby Neck, Nova Scotia between 1957 and 1992. The study includes an analysis of out-migration patterns historically from the early 1960s until the late 1990s, as well as a series of ethnographic educational and work history interviews drawn from samples of educators, "stayers" and "leavers."
