Equality for same-sex couples : a Canadian approach
Creators: name: Bonini-Baraldi, Matteo
Publisher: name: University of British Columbia
Year: 2009

description: In this thesis I start by reviewing the theoretical perspectives that have informed the debate around equality rights for gays and lesbians. Next, I will analyze the concept of equality developed by the Supreme Court of Canada under section 15 of the Canadian Charter of Rights and Freedoms. In the Andrews case, decided in 1989, the Supreme Court of Canada rejected a model based on formal equality, embracing instead the far-reaching concept of substantive equality as a way to redress historical prejudice and disadvantage of individuals and groups that fall within enumerated or analogous grounds of discrimination. In the last decade, a number of courts have applied this model to equality claims brought under the Charter by same-sex couples. I will explore the details of several of these cases as well as a variety of statutes relating to same-sex couples. Finally, I will discuss recent law reform proposals that recommend that state benefits should be allocated regardless of the relationship status of the beneficiaries, thereby envisaging more radical changes to the legal system. I conclude that the Canadian approach to equality for same-sex couples has followed an interpretive method that seems to apply a definition of family that is shifting and varies on an ad hoc basis, but that the denial of spousal status under marriage laws represents a limitation of equality rights still to be overcome. I also conclude that, in fact, the concept of status may still influence the adjudication process under section 15 of the Charter as far as marriage rights are concerned. This is because the framework of analysis under section 15 calls for an assessment of the claimant's position in the larger socio-political context, and this element, if not properly circumscribed, risks being corrupted by existing prejudices and biases relating to family.

A numerical study of a binary Yukawa model in regimes characteristic of globular proteins in solutions

description: The main goal of this paper is to assess the limits of validity, in the regime of low concentration and strong Coulomb coupling (high molecular charges), for a simple perturbative approximation to the radial distribution functions (RDF), based upon a low-density expansion of the potential of mean force and proposed to describe protein-protein interactions in a recent Small-Angle-Scattering (SAS) experimental study. A highly simplified Yukawa (screened Coulomb) model of monomers and dimers of a charged globular protein ($β$-lactoglobulin) in solution is considered. We test the accuracy of the RDF approximation, as a necessary complementary part of the previous experimental investigation, by comparison with the fluid structure predicted by approximate integral equations and exact Monte Carlo (MC) simulations. In the MC calculations, an Ewald construction for Yukawa potentials has been used to take into account the long-range part of the interactions in the weakly screened cases. Our results confirm that the perturbative first-order approximation is valid for this system even at strong Coulomb coupling, provided that the screening is not too weak (i.e., for Debye length smaller than monomer radius). A comparison of the MC results with integral equation calculations shows that both the hypernetted-chain (HNC) and the Percus-Yevick (PY) closures have a satisfactory behavior under these regimes, with the HNC being superior throughout. The relevance of our findings for interpreting SAS results is also discussed.

Step-size effect in the time-transformed leapfrog integrator on elliptic and hyperbolic orbits

description: A drift-kick-drift (DKD) type leapfrog symplectic integrator applied for a time-transformed separable Hamiltonian (or time-transformed symplectic integrator; TSI) has been known to conserve the Kepler orbit exactly. We find that for an elliptic orbit, such feature appears for an arbitrary step size. But it is not the case for a hyperbolic orbit: when the half step size is larger than the conjugate momenta of the mean anomaly, a phase transition happens and the new position jumps to the nonphysical counterpart of the hyperbolic trajectory. Once it happens, the energy conservation is broken. Instead, the kinetic energy minus the potential energy becomes a new conserved quantity. We provide a mathematical explanation for such phenomenon. Our result provides a deeper understanding of the TSI method, and a useful constraint of the step size when the TSI method is used to solve the hyperbolic encounters. This is particular important when an (Bulirsch-Stoer) extrapolation integrator is used together, which requires the convergence of integration errors.

description: The production structure of a selected cross-section sample of family owner-operated dairy farms is investigated using a translog variable cost function. Elasticities of scale, input substitution, and input own- and cross-price elasticities are estimated. At the sample mean herd size of 67 cows producing at 15,173 pounds of milk per cow, the elasticity of scale parameter was 1.00, implying constant returns to scale. The elasticities of substitution between feeds and hired labor and the own- and cross-price elasticities were inelastic.

The Zel'dovich effect and evolution of atomic Rydberg spectra along the Periodic Table

description: In 1959 Ya. B. Zel'dovich predicted that the bound-state spectrum of the non-relativistic Coulomb problem distorted at small distances by a short-range potential undergoes a peculiar reconstruction whenever this potential alone supports a low-energy scattering resonance. However documented experimental evidence of this effect has been lacking. Previous theoretical studies of this phenomenon were confined to the regime where the range of the short-ranged potential is much smaller than Bohr's radius of the Coulomb field. We go beyond this limitation by restricting ourselves to highly-excited s states. This allows us to demonstrate that along the Periodic Table of elements the Zel'dovich effect manifests itself as systematic periodic variation of the Rydberg spectra with a period proportional to the cubic root of the atomic number. This dependence, which is supported by analysis of experimental and numerical data, has its origin in the binding properties of the ionic core of the atom.

description: Flows of water pollutants from agricultural sources are, for all practical purposes, unobservable by direct monitoring. These flows can, however, be estimated using hydrological models. The analysis presented in this paper demonstrates that uncertainty on estimated flows is not neutral with respect to the optimal level and allocation of estimated abatement or with respect to the expected net benefits of alternative pollution control policy instruments. Policy implications are noted.
A New Version of Reimers' law of Mass Loss Based on a Physical Approach
Creators: name: Schroeder, K. -P.
name: Cuntz, M.
Publisher: name: arXiv
Year: 2005
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We present a new semi-empirical relation for the mass loss of cool stellar winds, which so far has frequently been described by "Reimers' law". Originally, this relation was based solely on dimensional scaling arguments without any physical interpretation. In our approach, the wind is assumed to result from the spill-over of the extended chromosphere, possibly associated with the action of waves, especially Alfven waves, which are used as guidance in the derivation of the new formula. We obtain a relation akin to the original Reimers law, but which includes two new factors. They reflect how the chromospheric height depends on gravity and how the mechanical energy flux depends, mainly, on effective temperature. The new relation is tested and sensitively calibrated by modelling the blue end of the Horizontal Branch of globular clusters. The most significant difference from mass loss rates predicted by the Reimers relation is an increase by up to a factor of 3 for luminous late-type (super-)giants, in good agreement with observations.

Superdeformation and clustering in $^{40}$Ca studied with Antisymmetrized Molecular Dynamics

Subjects: subject: Nuclear Theory (nucl-th)
subject: FOS: Physical sciences

description: Deformed states in $^{40}$Ca are investigated with a method of antisymmetrized molecular dynamics. Above the spherical ground state, rotational bands arise from a normal deformation and a superdeformation as well as an oblate deformation. The calculated energy spectra and $E2$ transition strengths in the superdeformed band reasonably agree to the experimental data of the superdeformed band starting from the $0^+_3$ state at 5.213 MeV. By the analysis of single-particle orbits, it is found that the superdeformed state has particle-hole nature of an $8p$-$8h$ configuration. One of new findings is parity asymmetric structure with $^{12}$C+$^{28}$Si-like clustering in the superdeformed band. We predict that $^{12}$C+$^{28}$Si molecular bands may be built above the superdeformed band due to the excitation of inter-cluster motion. They are considered to be higher nodal states of the superdeformed state. We also suggest negative-parity bands caused by the parity asymmetric deformation.

description: A longstanding open problem in mathematical physics has been that of finding an action principle for the Einstein-Weyl (EW) equations. In this paper, we present for the first time such an action principle in three dimensions in which the Weyl vector is not exact. More precisely, our model contains, in addition to the Weyl nonmetricity, a traceless part. If the latter is (consistently) set to zero, the equations of motion boil down to the EW equations. In particular, we consider a metric affine $f(R)$ gravity action plus additional terms involving Lagrange multipliers and gravitational Chern-Simons contributions. In our framework, the metric and the connection are considered as independent objects, and no a priori assumptions on the nonmetricity and the torsion of the connection are made. The dynamics of the Weyl vector turns out to be governed by a special case of the generalized monopole equation, which represents a conformal self-duality condition in three dimensions.

description: Regional economic growth based on private sector job creation is often proposed as a policy for reducing the incidence of regional unemployment, poverty and dependency. One factor that could limit the impact of economic growth on the employment and poverty status of an area's indigenous population is the area's public assistance system. This study evaluates the impact of recent changes in federal welfare legislation (HR 3982) on the work incentives and the poverty and dependency status of Delaware female household heads receiving Aid to Families with Dependent Children (AFDC) assistance. Specifically, the study estimates the implicit marginal tax rates that such household heads would face by accepting employment in private sector jobs to which they are potential entrants under the pre and post HR 3982 conditions. In addition, the study examines the effect of the HR 3982 changes on the poverty and dependency status of such households.

description: Initial results are presented from 3D MHD modelling of stellar-wind bubbles around O stars moving supersonically through the ISM. We describe algorithm updates that enable high-resolution 3D MHD simulations at reasonable computational cost. We apply the methods to the simulation of the astrosphere of a rotating massive star moving with 30 km/s through the diffuse interstellar medium, for two different stellar magnetic field strengths, 10 G and 100 G. Features in the flow are described and compared with similar models for the Heliosphere. The shocked interstellar medium becomes asymmetric with the inclusion of a magnetic field misaligned with the star's direction of motion, with observable consequences. When the Alfvenic Mach number of the wind is $\leq$10 then the stellar magnetic field begins to affect the structure of the wind bubble and features related to the magnetic axis of the star become visible at parsec scales. Prospects for predicting and measuring non-thermal radiation are discussed.

description: We provide a uniform decay estimate of Morawetz type for the local energy of general solutions to the inhomogeneous wave equation on a Schwarzchild background. This estimate is both uniform in space and time, so in particular it implies a uniform bound on the sup norm of solutions which can be given in terms of certain inverse powers of the radial and advanced/retarded time coordinate variables. As a model application, we show these estimates give a very simple proof small amplitude scattering for nonlinear scalar fields with higher than cubic interactions.

Learning from example : exploring immigrant language minority students’ perceptions of what it takes to "make it" as an ESL student
Creators: name: Séror, Jérémie
Publisher: name: University of British Columbia
Year: 2009

description: Successful students who are immigrant language minority students (ILMS) and who were once identified as ESL learners tend to standout in the Greater Vancouver area since academic achievement tends to be the exception rather than the rule for these students. Only a small proportion appears to graduate from high school and/or pursue studies at a post-secondary level (Gunderson, 2000). If one believes that, in general, all children have what it takes to discover and learn about the world that surrounds them, and how to become an active participant in it, then one has to wonder why so many are failing. Moreover, one can ask what the few who are making it are actually doing that allows them to "beat the odds". This study attempted to explore this question through a series of qualitative iridepth interviews with fifteen 'ex-ESL students' from the Greater Vancouver area. The interviews focused on their perceptions of the factors having influenced their successful academic achievement and integration process as defined by their ability to enter a Canadian university. The importance of the special challenges that the education of ILMS presents for all involved is stressed, followed by a discussion of how these challenges were perceived, faced and overcome by the ILMS in this study. Special emphasis is put on the importance of sociocultural aspects such as the establishment of a strong sense of selfworth, strong relationships with family and friends, the preservation of home language(s) and culture(s) and prior school experiences as keys to social and academic achievement. This thesis also identifies interesting paradoxes in the way the informants perceived their educational experiences. Informants commented, for example, on the safe, yet segregating ESL classrooms and the importance of both individual and collective effort. In summarizing and discussing the comments and advice given by ILMS it is hoped that more people may gain a greater understanding of what ILMS have to face and what it takes to help make success the rule rather than the exception.

description: In this paper we utilize techniques from the theory of non-linear dynamical systems to define a notion of embedding threshold estimators. More specifically we use delay-coordinates embeddings of sets of coefficients of the measured signal (in some chosen frame) as a data mining tool to separate structures that are likely to be generated by signals belonging to some predetermined data set. We describe a particular variation of the embedding threshold estimator implemented in a windowed Fourier frame, and we apply it to speech signals heavily corrupted with the addition of several types of white noise. Our experimental work seems to suggest that, after training on the data sets of interest,these estimators perform well for a variety of white noise processes and noise intensity levels. The method is compared, for the case of Gaussian white noise, to a block thresholding estimator.

description: Biodiversity is about more than plants, animals, and micro-organisms and their ecosystems – the Convention on Biological Diversity (CBD, 1992) recognizes that it is also very much about people and our need for food security, medicines, fresh air, shelter, and a clean and healthy environment. Biodiversity is also essential for the maintenance of ecosystem-based services, such as the provision of water and food for human, animal and plant life. When we make an effort to conserve biodiversity, we are helping to maintain critical global biological resources to meet our needs today as well as those of future generations. Biodiversity conservation is therefore central to achieving recent global commitments for sustainable development under “Agenda 2030”, adopted by the United Nations in 2015. The International Fund for Agricultural Development (IFAD) recognizes that losing biodiversity means losing opportunities for coping with future challenges, such as those posed by climate change and food insecurity.

description: Recent observations have revealed the presence of small fibres or sub-filaments within larger filaments. We present a numerical fragmentation study of fibrous filaments investigating the link between cores and sub-filaments using hydrodynamical simulations performed with the moving-mesh code Arepo. Our study suggests that cores form in two environments: (i) as isolated cores, or small chains of cores, on a single sub-filament, or (ii) as an ensemble of cores located at the junction of sub-filaments. We term these isolated and hub cores respectively. We show that these core populations are statistically different from each other. Hub cores have a greater mean mass than isolated cores, and the mass distribution of hub cores is significantly wider than isolated cores. This fragmentation is reminiscent of parsec-scale hub-filament systems, showing that the combination of turbulence and gravity leads to similar fragmentation signatures on multiple scales, even within filaments. Moreover, the fact that fragmentation proceeds through sub-filaments suggests that there exists no characteristic fragmentation length-scale between cores. This is in opposition to earlier theoretical works studying fibre-less filaments which suggest a strong tendency towards the formation of quasi-periodically spaced cores, but in better agreement with observations. We also show tentative signs that global collapse of filaments preferentially form cores at both filament ends, which are more massive and dense than other cores.

description: Cognitive Radio (CR) promises an efficient utilization of radio spectrum resources by enabling dynamic spectrum access to overcome the spectrum scarcity problem. Cognitive Radio Sensor Networks (CRSNs) are one type of Wireless Sensor Networks (WSNs) equipped with CR capabilities. CRSN nodes need to operate energy-efficiently to extend network lifetime due to their limited battery capacity. In this paper, for the first time in literature, we formulate the problem of finding a common energy-efficient transmission range and transmission duration for all CRSN nodes and network deployment that would minimize the energy consumed per goodput per meter toward the sink in a greedy forwarding scenario. Results reveal non-trivial relations for energy-efficient CRSN transmission range and duration as a function of nine critical network parameters such as primary user activity levels. These relations provide valuable insights for detailed CRSN designs prior to deployment.

I presented the Phoenix-OoC mission as a point of arrival by way of showing my different maximum influential works that allowed me to get to this undertaking. I highlighted the distinct benefits of the use of paper in biosensor improvement, as mentioned in my review, "Electrochemical paper-based devices: When the simple replacement of the support to print ecodesigned electrodes radically improves the features of the electrochemical devices" published in  Current Opinion in Electrochemistry SI: Emerging Opinions (2022) [F. Arduini. Curr. Opin. Electrochem. 2022, 101090]: “Paper-based electrochemical (bio)sensors have emerged as highly attractive analytical devices for their superior sustainable features, such as avoiding the use of polyester as support and the reduction of waste, being incinerated after use. However, paper-based electrochemical (bio)sensors have recently demonstrated further advantages, including the simple combination with vertical microfluidics and their use as a reservoir to deliver smart electrochemical (bio)sensors able to i) contain the reagents, ii) preconcentrate the target analyte, and iii) synthesize the nanomaterials inside the paper network. Furthermore, these devices have demonstrated their ability to overcome the limitations of the other printed electrochemical sensors in the measurement of entirely liquid samples by detecting the target analyte in the aerosol phase or solid sample, without the additional sampling system. These achievements highlight their valuable and varied advantages in the sensing sector”.

description: A new polarization survey of the northern sky at 1.41 GHz is presented. The observations were carried out using the 25.6m telescope at the Dominion Radio Astrophysical Observatory in Canada, with an angular resolution of 36 arcmin. The data are corrected for ground radiation to obtain Stokes U and Q maps on a well-established intensity scale tied to absolute determinations of zero levels, containing emission structures of large angular extent, with an rms noise of 12 mK. Survey observations were carried out by drift scanning the sky between -29 degr and +90 degr declination. The fully sampled drift scans, observed in steps of 0.25 degr to 2.5 degr in declination, result in a northern sky coverage of 41.7% of full Nyquist sampling. The survey surpasses by a factor of 200 the coverage, and by a factor of 5 the sensitivity, of the Leiden/Dwingeloo polarization survey (Spoelstra 1972) that was until now the most complete large-scale survey. The temperature scale is tied to the Effelsberg scale. Absolute zero-temperature levels are taken from the Leiden/Dwingeloo survey after rescaling those data by the factor of 0.94. The paper describes the observations, data processing, and calibration steps. The data are publicly available at http://www.mpifr-bonn.mpg.de/div/konti/26msurvey or http://www.drao.nrc.ca/26msurvey.

description: We construct smooth non-supersymmetric soliton solutions with D1-brane, D5-brane and momentum charges in type IIB supergravity compactified on T^4 x S^1, with the charges along the compact directions. This generalises previous studies of smooth supersymmetric solutions. The solutions are obtained by considering a known family of U(1) x U(1) invariant metrics, and studying the conditions imposed by requiring smoothness. We discuss the relation of our solutions to states in the CFT describing the D1-D5 system, and describe various interesting features of the geometry.

Some Aspects of Fundamental Symmetries and Interactions

description: The known fundamental symmetries and interactions are well described by the Standard Model. Features of this powerful theory, which are described but not deeper explained, are addressed in a variety of speculative models. Experimental tests of the predictions in such approaches can be either through direct observations at the highest possible accelerator energies or through precision measurements in which small deviations from calculated values within the Standard Model are searched for. Antiproton physics renders a number of possibilities to search for new physics.

description: We present a formulation of Regge Calculus where arbitrary coordinates are associated to each vertex of a simplicial complex and the degrees of freedom are given by the metric on each simplex. The lengths of the edges are thus determined and are left invariant under arbitrary transformations of the discrete set of coordinates, provided the metric transforms accordingly. Invariance under coordinate transformations entails tensor calculus and our formulation follows closely the usual formalism of the continuum theory. The definitions of parallel transport, Christoffel symbol, covariant derivatives and Riemann curvature tensor follow in a rather natural way. In this correspondence Einstein action becomes Regge action with the deficit angle $θ$ replaced by $\sin θ$. The correspondence with the continuum theory can be extended to actions with higher powers of the curvature tensor, to the vielbein formalism and to the coupling of gravity with matter fields (scalars, fermionic fields including spin $3/2$ fields and gauge fields) which are then determined unambiguously and discussed in the paper. An action on the simplicial lattice for $N=1$ supergravity in $4$ dimensions is derived in this context. Another relavant result is that Yang-mills actions on a simplicial lattice consist, even in absence of gravity, of two plaquettes terms, unlike the one plaquette Wilson action on the hypercubic lattice. An attempt is also made to formulate a discrete differential calculus to include differential forms of higher order and the gauging of free differential algebras in this scheme. However this leads to form products that do not satisfy associativity and distributive law with respect to the $d$ operator. A proper formulation of theories that contain higher order differential forms in the context of Regge Calculus is then still lacking.

Genre analysis of research grant proposals
Creators: name: Feng, Haiying
Publisher: name: University of British Columbia

description: Research grant proposals are a very important genre in many academic disciplines, and a window into which we are able to observe academic engagements and interactions. However, there has been little textual analysis of the genre and research on how successful scholars approach the writing task. Drawing on the social constructionist genre scholarship, this study collected and analyzed nine successful SSHRC (Social Sciences and Humanities Research Council of Canada) research grant proposals from nine professors in the field of education at a Canadian university. The proposals were examined in terms of three important textual features: generic structure, referential behavior, hedges and boosters. Semi-structured discourse-based interviews with the nine professors as insider informants were also conducted. The main findings of the study include the following: (1) A three-move scheme was developed in this study as reflecting the generic structure of research grant proposal summaries. In analyzing the main text of research grant proposals, I first recognized the ICMC pattern (Introduction-Context-Methodology-Communication of Results) as the overall structure; ten moves as the constitutive functional components were then identified under this pattern. (2) Non-integral (where the name of the cited author does not appear in the actual citing sentence), non-reporting (where no reporting verb such as show, establish, suggest is employed to introduce the cited work), and generalization (where the proposition is attributed to two or more sources) forms of citations were found to be predominantly used in the research grant proposals. Self-citation was also used with a high frequency in this genre. 3) The use of boosters was found to exceed the use of hedges, and the distribution of hedges and boosters were found uneven across the rhetorical sections. Interviews with the nine professors further reveal how communicative purposes, institutional practice, and reader-writer relationship co-constructed the format as well as the stylistic features of grant writing. The study provides genre analysts as well as novice grant writers some useful insights into the research grant proposal writing.
Rapid refractive index enhancements via laser-mediated collectivity

description: The collective interaction via the environmental vacuum is investigated for a mixture of two deviating multi-atom ensembles in a moderately intense laser field. Due to the numerous inter-atomic couplings, the laser-dressed system may react sensitively and rapidly with respect to changes in the atomic and laser parameters. We show for weak probe fields that in the absence of absorption both the index of refraction and the group velocity may be modified strongly and rapidly due to the collectivity.

 Ochterus parvus Schell, 1943a: 32, 35 (key to species, illustration). LECTOTYPE (designated by SCHELL 1943b: 40, as holotype):, Ecuador: ‘Mera’ (SEMC).
 Ochterus parvus: SCHELL (1943b): 39 –40 (original description, differential diagnosis); DRAKE (1952): 74 (checklist); FROESCHNER (1981): 61 (catalogue); HECKMAN (2011): 460 (key to species, illustration); CIANFERONI (2012): 67 (key to species).
 Material examined. ECUADOR: NAPO: 7.5 km SE of Archidona, San Pablo de Ushpayacu env., 0°56′52″S 77°45′01″W, 540 m a.s.l., 23.xi.2006, 1 ♀ (Fig. 24), M. Fikáček lgt., P. Kment det. (NMPC).
  Distribution. Neotropical Region:  South America: Ecuador (SCHELL 1943b, DRAKE 1952, CIANFERONI 2012).
 Note. The revision of American Ochterus including the description of O. parvus was published divided in two parts, the first published in January 1943 (SCHELL 1943a) and the second in April 1943 (SCHELL 1943b). The species was first introduced in the key, which is sufficient to make it available (ICZN 1999: Art. 13.1.1), without any mention of type specimens (SCHELL 1943a: 32), while the original description including the holotype designation appeared in the second part (SCHELL 1943b: 39). As a holotype is defined as ‘the single specimen upon which a new nominal species-group taxon is based in the original publication’ (ICZN 1999: Art. 73.1), in this case, the subsequently designated ‘holotype’ must be considered the lectotype according to ICZN (1999: Art. 74.5).

 Ochterus paucistriata Baehr, 1990b: 450, 453, 454, 456–459, 461, 468 ‒469 (key to species, description, illustrations). HOLOTYPE:, Indonesia: Papua:ʻDutch New Guinea: Cyclops Mts., Mt.Lina, 3500 ft. [= 1067 m a.s.l.]’ (BMNH).
 Ochterus paucistriata: CHEN et al. (2005): 413 (checklist).
  Distribution. Australian Region:  Indonesia: Papua (BAEHR 1990b, CHEN et al. 2005)
 Note. BAEHR (1990b) established the species name as O. paucistriata, citing it 11 times throughout the paper, but without providing any explanation of its etymology. CHEN et al. (2005) also accepted O. paucistriata as the correct original spelling. However, the species name is a compo-
 sed Latin adjective paucistriatus (- a, - um) and the generic name Ochterus is masculine. Therefore, we correct here the gender agreement of the name to O. paucistriatus (see ICZN 1999: Art. 31.2, 34.2).

description: Optimal entry and exit thresholds for Georgia commercial peach production are calculated when both price and yield follow a Brownian motion process. The thresholds are based on an irreversible sunk-cost investment model, where revenue from peach production is affected by the timing of when to enter production. Results indicate stability in Georgia peach production, with growers who are currently producing peaches remaining in production and potential peach growers delaying investment unless they have the ability of earning enhanced returns.
