The 1986 election of W.N. Vander Zalm as leader of the B.C. Social Credit party
Creators: name: McCarthy, William P.J.
Publisher: name: University of British Columbia
Year: 2009

description: This thesis is a review and analysis of the selection of William N. Vander Zalm as the third leader of the British Columbia Social Credit party on July 30, 1986. It examines in detail the events and circumstances which allowed the last candidate to enter the most contested leadership race in Canadian history to win the convention. This thesis incorporates an overview of the British Columbia Social Credit party, its traditions, leaders, and criteria for selecting its leaders. The sixty-nine day campaign is chronicled and the other eleven candidates and their campaigns are examined. In addition to reviewing the public and private record on these matters, several interviews were conducted. This thesis also benefits greatly from the analysis and articles on the Social Credit leadership contests produced by the University of British Columbia’s Political Science department. Personal observations are also incorporated into this paper, as the writer was a voting delegate. (I have been a Social Credit party member since 1981. At the leadership convention I supported Vander Zalm on all four ballots. While I readily acknowledge my political biases, I nevertheless have endeavoured to write a balanced academic account of this event). The Vander Zalm victory contradicts much of the conventional wisdom on the organization and conduct of successful leadership campaigns. The Vander Zalm campaign effort was poorly organized with no real strategic planning. The campaign finances were modest. The candidate had little caucus support and no endorsements from the party elites. Furthermore, the candidate did not enter the contest until it was half over and eleven other candidates were already in the race. How then did he win? In this thesis, I argue that the Vander Zalm victory was the result of four factors, all linked and all essential to his success. First, Vander Zalm himself offered a populist style and persona many delegates found attractive. Second, the party’s antiquated constitution provided only one delegate category, those selected directly by the membership. This not only prevented manipulation or control of delegate categories (as seen in other party contests), but ensured that several long-time party activists who were predisposed to the Vander Zalm candidacy would emerge as delegates. Third, Vander Zalm’s candidacy was boosted greatly by polls during the campaign showing him to be the party’s best hope to lead them to victory in the upcoming provincial election. And finally, many delegates saw a vote for Vander Zalm as a means to repudiate the modernization and isolation of the party and government seen during the last years of outgoing Premier W.R. Bennett, and return the party to its populist origins.

description: We present optical spectroscopy of several (candidate) ultra-compact X-ray binaries (UCXBs) obtained with the ESO VLT and Gemini-North telescopes. In only one of five observed UCXB candidates did we find evidence for H in its spectrum (4U 1556-60). For XB 1905+00 the optical counterpart is not detected. For the known UCXBs 4U 1626-67 and XB 1916-05 we find spectra consistent with a C/O and a He/N accretion disc respectively, the latter is the first optical spectrum of a He-rich donor in an UCXB. Interestingly, the C/O spectrum of 4U 1626-67 shows both similarities as well as marked differences from the optical C/O spectrum of 4U 0614+09. We obtained phase resolved spectroscopy of 4U 0614+09 and the 44 min transient XTE J0929-314. In neither object were we able to detect clear orbital periodicities, highlighting the difficulties of period determinations in UCXBs. We reanalysed the spectra of XTE J0929-314 that were taken close to the peak of its 2003 X-ray outburst and do not confirm the detection of Halpha emission as was claimed in the literature. The peak spectra do show strong C or N emission around 4640A, as has also been detected in other UCXBs. We discuss the implications of our findings for our understanding of the formation of UCXBs and the Galactic population of UCXBs. At the moment all studied systems are consistent with having white dwarf donors, the majority being C/O rich.

description: Η μελέτη της περιοδικότητας διάφορων φαινομένων αποτελούσε ανέκαθεν αναπόσπαστο κομμάτι του τομέα της Στατιστικής. Παράλληλα ένα από τα μεγαλύτερα επιτεύγματα της ανθρωπότητας, η ανακάλυψη της δομής του γενετικού υλικού τον εικοστό αιώνα, ώθησε την επιστημονική κοινότητα στην αναζήτηση πιθανών εφαρμογών περιοδικότητας στην αλληλουχία των βάσεων του DNA και συνεπώς στην άμεση συσχέτιση των δύο κλάδων. Από την μέχρι τώρα μελέτη της αλληλουχίας των αζωτούχων βάσεων του γενετικού κώδικα έχει διαπιστωθεί ότι το DNA εμφανίζει περιοδικότητα, συχνά λανθάνουσα, τόσο στις περιοχές που μεταφράζονται σε πρωτεΐνες (exons), όσο και στις introns περιοχές. Στην παρούσα εργασία γίνεται μια μελέτη πάνω στις πρωταρχικές έννοιες της δομής του DNA και στη συνέχεια αναφέρονται ορισμένες μαθηματικές μέθοδοι μελέτης και εντοπισμού περιοδικότητας οι οποίες είναι δυνατόν να βρουν εφαρμογή στην αλυσίδα του γενετικού υλικού.

description: The study of periodicity in various phenomena has always been an integral part of statistics. At the same time, one of humanity’s greatest achievements, the discovery of the structure of genetic material, urged the scientific community to seek after any possible applicability of periodicity in the sequence of nucleotides and consequently to correlate the two disciplines. Through research studies done hitherto, it has been proved that DNA does demonstrate periodicity, often latent, in coding regions (exons), as well as in intron regions. In the present research paper the primary concepts of DNA structure are probed, and afterwards, specific mathematic methods of studying and detecting periodicity, which are possible to be implemented in the sequence of genetic material, are approached. More particularly, the methods, which employ the Fourier transform or mutual information, are analyzed, as well as periodicity is detected in time domain methods. Furthermore, a method of detecting periodicity in labeled data is described and eventually an example of implementation and verification of the method’s validity is accomplished.

description: Software testing is one of the very important Quality Assurance (QA) components. A lot of researchers deal with the testing process in terms of tester motivation and how tests should or should not be written. However, it is not known from the recommendations how the tests are written in real projects. In this paper, the following was investigated: (i) the denotation of the word "test" in different natural languages; (ii) whether the number of occurrences of the word "test" correlates with the number of test cases; and (iii) what testing frameworks are mostly used. The analysis was performed on 38 GitHub open source repositories thoroughly selected from the set of 4.3M GitHub projects. We analyzed 20,340 test cases in 803 classes manually and 170k classes using an automated approach. The results show that: (i) there exists a weak correlation (r = 0.655) between the number of occurrences of the word "test" and the number of test cases in a class; (ii) the proposed algorithm using static file analysis correctly detected 97% of test cases; (iii) 15% of the analyzed classes used main() function whose represent regular Java programs that test the production code without using any third-party framework. The identification of such tests is very complex due to implementation diversity. The results may be leveraged to more quickly identify and locate test cases in a repository, to understand practices in customized testing solutions, and to mine tests to improve program comprehension in the future.

description: The aim of the present thesis was the study of the bank deposit in a joint account. To achieve this goal initially attempted to approximate notions of bank deposit in general. Subsequently developed the issue of the legal nature of the particular class deposit in an account opened in the name of two or more individuals, with the special condition that either one or all beneficiaries can make use of the account by depositing without the involvement of others. Then examined the function of this type of banking deposit through specific use cases of the relevant account, ie disposal in general, the assignment requirement of a joint account, pledge structures of joint account and the case of undertaking of the entire deposit. Finally, attempted to study the specific issues of joint holder’s death, banking secrecy, seizure of deposit a joint account and rights of netting and lien.

description: We explore thermodynamic contributions to the three-dimensional de Sitter horizon originating from metric and Chern-Simons gauge field fluctuations. In Euclidean signature these are computed by the partition function of gravity coupled to matter semi-classically expanded about the round three-sphere saddle. We investigate a corresponding Lorentzian picture - drawing inspiration from the topological entanglement entropy literature - in the form of an edge-mode theory residing at the de Sitter horizon. We extend the discussion to three-dimensional gravity with positive cosmological constant, viewed (semi-classically) as a complexified Chern-Simons theory. The putative gravitational edge-mode theory is a complexified version of the chiral Wess-Zumino-Witten model associated to the edge-modes of ordinary Chern-Simons theory. We introduce and solve a family of complexified Abelian Chern-Simons theories as a way to elucidate some of the more salient features of the gravitational edge-mode theories. We comment on the relation to the AdS$_4$/CFT$_3$ correspondence.

Adhesive wear regimes on rough surfaces and interaction of micro-contacts

Year: 2021
Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: We develop an analytical model of adhesive wear between two unlubricated rough surfaces, forming micro-contacts under normal load. The model is based on an energy balance and a crack initiation criteria. We apply the model to the problem of self-affine rough surfaces under normal load, which we solve using the boundary element method. We discuss how self-affinity of the surface roughness, and the complex morphology of the micro-contacts that emerge for a given contact pressure, challenge the definition of contact junctions. Indeed, in the context of adhesive wear, we show that elastic interactions between nearby micro-contacts can lead to wear particles whose volumes enclose the convex hull of these micro-contacts. We thereby obtain a wear map describing the instantaneous produced wear volume as a function of material properties, roughness parameters and loading conditions. Three distinct wear regimes can be identified in the wear map. In particular, the model predicts the emergence of a severe wear regime above a critical contact pressure, when interactions between micro-contacts are favored.

description: A nucleon-nucleus interaction model has been applied to ascertain the underlying character of the negative-parity spectra of four isobars of mass seven, from neutron-- to proton--emitter driplines. With one single nuclear potential defined by a simple coupled-channel model, a multichannel algebraic scattering approach (MCAS) has been used to determine the bound and resonant spectra of the four nuclides, of which ^7He and ^7B are particle unstable. Incorporation of Pauli blocking in the model enables a description of all known spin-parity states of the mass-7 isobars. We have also obtained spectra of similar quality by using a large space no-core shell model. Additionally, we have studied ^7Li and ^7Be using a dicluster model. We have found a dicluster-model potential that can reproduce the lowest four states of the two nuclei, as well as the relevant low-energy elastic scattering cross sections. But, with this model, the rest of the energy spectra cannot be obtained.

description: The dynamics of particles interacting by key-lock binding of attached biomolecules are studied theoretically. Experimental realizations of such systems include colloids grafted with complementary single-stranded DNA (ssDNA), and particles grafted with antibodies to cell-membrane proteins. Depending on the coverage of the functional groups, we predict two distinct regimes. In the low coverage localized regime, there is an exponential distribution of departure times. As the coverage is increased the system enters a diffusive regime resulting from the interplay of particle desorption and diffusion. This interplay leads to much longer bound state lifetimes, a phenomenon qualitatively similar to aging in glassy systems. The diffusion behavior is analogous to dispersive transport in disordered semiconductors: depending on the interaction parameters it may range from a finite renormalization of the diffusion coefficient to anomalous, subdiffusive behavior. We make connections to recent experiments and discuss the implications for future studies.

description: An internal governance structure is essential for EdiCitNet to connect across the diversity of sectors, disciplines and cultural contexts of our partners. Governing for social inclusion goes beyond formal government approaches to include public, private (business) and civil society (community) sectors. New forms of urban governance are required to engage with such a diversity of stakeholders beyond traditional governance forms. Given the diversity of the participants and the high reliance on collaborative goodwill the governance model will require relational modes of engagement rather than simply transactional modes. The purpose of this document is to support EdiCitNet achieve three main objectives: 1. To establish clear and accountable governance and communications processes to underpin the institutional backbone of EdiCitNet; 2. To design a functional governance framework for efficient stakeholder engagement across the EdiCitNet project and within each participating city; and, 3. To develop an active international Edible Cities ‘network of networks’. Strong interpersonal relationships with partners are essential for achieving our aims, as are recognizing the specificities, values, and resources existing within local contexts. Based on the relationships and learnings developed over the course of the project, we aim: ● To foresee and manage emerging risks ● To ensure consistent and effective collaboration for all partners ● To co-design the governance model with both the cities and the Consortium ● To facilitate the sharing of information on progress among cities ● To facilitate mainstreaming ECS into existing institutional, regulatory and decision-making frameworks at the municipal scale ● For this infrastructure, knowledge and support base to provide the jump off point for the internationalization of the network. The diverse contexts for each City Team mean that no set template can be uniformly applied. However general guidance that empowers local groups to work collaboratively can be offered. Such guidance needs to be flexible and adaptable to allow cities to tailor their participation to their needs and context, and to facilitate experimentation to nurture new possibilities3. We have consulted with partners across the project to identify key goals and concerns towards these considerations.

description: Recently, it has been claimed that some complex networks are self-similar under a convenient renormalization procedure. We present a general method to study renormalization flows in graphs. We find that the behavior of some variables under renormalization, such as the maximum number of connections of a node, obeys simple scaling laws, characterized by critical exponents. This is true for any class of graphs, from random to scale-free networks, from lattices to hierarchical graphs. Therefore, renormalization flows for graphs are similar as in the renormalization of spin systems. An analysis of classic renormalization for percolation and the Ising model on the lattice confirms this analogy. Critical exponents and scaling functions can be used to classify graphs in universality classes, and to uncover similarities between graphs that are inaccessible to a standard analysis.

Social movement politics and the charter of rights outside the courts
Creators: name: James, Matt
Publisher: name: University of British Columbia
Year: 2009

description: It is often argued that such 'new social movements' as lesbian and gay rights, feminism, and anti-racism nourish aspirations which are completely different from those advanced by their orthodox socialist predecessors. Contemporary social change politics, it is held, are informed by 'postmaterialist' values. This study, "Social Movement Politics and the Charter of Rights Outside the Courts," challenges such a view by analyzing the testimony made by a range of social movement organizations before the Canadian federal government's 1992 special parliamentary committee hearings on the constitution. "Social Movement Politics and the Charter of Rights Outside the Courts" reveals that so-called postmaterialist groups (such as feminist, lesbian and gay and anti-racist organizations) are concerned emphatically with material issues. At the same time, 'materialist' groups like unions and antipoverty organizations demonstrate a profound concern for their symbolic status in the political community, thus confounding the postmaterialism dichotomy. Therefore, this study argues, the postmaterialist dichotomy is too crude an analytic tool for capturing contemporary social change struggles accurately. Instead, the full range of social movements, 'new' and 'old', must be reassessed. In Canada, the new presence of the Charter of Rights and Freedoms has proven a rallying point for all major contemporary social change movements. It provides a common institutional context of action within which social change politics can be studied. This study's analysis of the discursive use of the Charter by social movement organizations isolates several emergent distinctions among social movements that will prove crucial to the evolution of social change politics in Canada. These are: 1) the contrasting institutional identifications of antimajoritarian and state-expansionist groups, which are induced by the new availability of justiciable rights; 2) the divergent attitudes evinced by ethnic and visible minorities towards the norms established by the Charter's sections 15 and 27; 3) the considerable difference in political advantage that Charter enumeration gives recognized over unrecognized movements.

description: The spin-galvanic effect and the circular photogalvanic effect induced by terahertz radiation are applied to determine the relative strengths of Rashba and Dresselhaus band spin-splitting in (001)-grown GaAs and InAs based two dimensional electron systems. We observed that shifting the $δ$-doping plane from one side of the quantum well to the other results in a change of sign of the photocurrent caused by Rashba spin-splitting while the sign of the Dresselhaus term induced photocurrent remains. The measurements give the necessary feedback for technologists looking for structures with equal Rashba and Dresselhaus spin-splittings or perfectly symmetric structures with zero Rashba constant.

description: This work aims to investigate the corrosion inhibition of the mild steel in the 1 M HCl solution by 1-octyl-3-methylimidazolium hydrogen sulphate 1-butyl-3-methylimidazolium hydrogen sulphate, and 1-octyl-3-methylimidazolium chloride, using electrochemical, weight loss, and surface analysis methods as well as the full quantum-mechanical treatment. Polarization measurements prove that studied compounds are mixed-type inhibitors with a predominantly anodic reaction. The inhibition efficiency obtained from the polarization curves is about 80-92% for all of the 1-octyl-3-methylimidazolium salts with a concentration higher than 0.005 mol/l, while it is much lower for 1-butyl-3-methylimidazolium hydrogen sulphate. The values measured in the weight loss experiments (after seven days) are to some extent higher (reaching up to 98% efficiency). Furthermore, we have shown that the influence of the alkyl chain length on the inhibition efficiency is much larger than that of the anion type. Furthermore, we obtain a realistic model of a single molecule on iron surface Fe(110) by applying the Density Functional Theory calculations. We use the state-of-the-art computational approach, including the meta-GGA strongly-constrained and appropriately normed semilocal density functional to model the electronic structure properties of both free and bounded-to-surface molecules of 1-butyl-, 1-hexyl-, and 1-octyl-3-methylimizadolium bromide, chloride, and hydrogen sulphate. From the calculations we extract, the HOMO/LUMO gap, hardness, electronegativity, and charge transfer of electrons from/to molecules-in-question. It supports the experimental findings and explains the influence of the alkyl chain length and the functional group on the inhibition process.

description: Future long-baseline neutrino experiments will measure neutrino oscillation properties with unprecedented precision and will search for clear signatures of CP violation in the leptonic sector. Near detectors can measure the neutrino-electron scattering with high statistics, giving the chance for its precise measurement. We study, in this work, the expectations for the measurement of radiative corrections in this process. We focus on the determination of contributions that are exclusive to the neutrino channels, particularly on the neutrino charge radius. We illustrate how the perspectives in a first clear measurement of this effective quantity are encouraging.

description: We have studied the three-body recombination rates on both sides of the interspecies d-wave Feshbach resonance in the $^{85}$Rb\,-$^{87}$Rb-$^{87}$Rb system using the $R$-matrix propagation method in the hyperspherical coordinate frame. Two different mechanisms of recombination rate enhancement for positive and negative $^{85}$Rb\,-$^{87}$Rb d-wave scattering lengths are analyzed. On the positive scattering length side, the recombination rate enhancement occurs due to the existence of three-body shape resonance, while on the negative scattering length side, the coupling between the lowest entrance channel and the highest recombination channel is crucial to the appearance of the enhancement. In addition, our study shows that the intraspecies interaction plays a significant role in determining the emergence of recombination rate enhancements. Compared to the case in which the three pairwise interactions are all in d-wave resonance, when the $^{87}$Rb-$^{87}$Rb interaction is near the d-wave resonance, the values of the interspecies scattering length that produce the recombination enhancement shift. In particular, when the $^{87}$Rb-$^{87}$Rb interaction is away from the d-wave resonance, the enhancement disappears on the negative interspecies scattering length side.

description: At the magnetic saturation field, certain frustrated lattices have a class of states known as "localized multi-magnon states" as exact ground states. The number of these states scales exponentially with the number $N$ of spins and hence they have a finite entropy also in the thermodynamic limit $N\to \infty$ provided they are sufficiently linearly independent. In this article we present rigorous results concerning the linear dependence or independence of localized magnon states and investigate special examples. For large classes of spin lattices including what we called the orthogonal type and the isolated type as well as the kagomé, the checkerboard and the star lattice we have proven linear independence of all localized multi-magnon states. On the other hand the pyrochlore lattice provides an example of a spin lattice having localized multi-magnon states with considerable linear dependence.

description: In relativistic Quantum Field Theory (QFT) ideal measurements of certain observables are physically impossible without violating causality. This prompts two questions: i) can a given observable be ideally measured in QFT, and ii) if not, in what sense can it be measured? Here we formulate a necessary and sufficient condition that any measurement, and more generally any state update (quantum operation), must satisfy to respect causality in real scalar QFT. We argue that for unitary `kicks' and operations involving 1-parameter families of Kraus operators, e.g. Gaussian measurements, the only causal observables are smeared fields and the identity -- the basic observables in real scalar QFT. We provide examples with more complicated operators such as products of smeared fields, and show that the associated state updates are acausal, and hence impossible. Despite this, one can still recover expectation values of such operators, and we show how to do this using only causal measurements of smeared fields.

description: The E799-II (KTeV) experiment at Fermilab has collected 83262 $K_L \to e^+e^-γ$ events above a background of 79 events. We measure a decay width, normalized to the $K_L \to π^0π^0π^0_D$ (π^0 \to γγ, π^0 to γγ, π^0_D \to e^+e^-γ) decay width, of $Γ($K_L \to e^+e^-γ$)/Γ(K_L \to π^0π^0π^0_D) = (1.3302 \pm 0.0046_{stat} \pm 0.0102_{syst}) \times 10^{-3}$. We also measure parameters of two $K_L γ^{\ast}γ$ form factor models. In the Bergstrom, Masso, and Singer (BMS) parametrization, we find $\caks = -0.517 \pm 0.030_{stat} \pm 0.022_{syst}$. We separately fit for the first parameter of the D'Ambrosio, Isidori, and Portoles (DIP) model and find $\adip = -1.729 \pm 0.043_{stat} \pm 0.028_{syst}$.

description: Symmetries in a network connectivity regulate how the graph's functioning organizes into clustered states. Classical methods for tracing the symmetry group of a network require very high computational costs, and therefore they are of hard, or even impossible, execution for large sized graphs. We here unveil that there is a direct connection between the elements of the eigen-vector centrality and the clusters of a network. This gives a fresh framework for cluster analysis in undirected and connected graphs, whose computational cost is linear in $N$. We show that the cluster identification is in perfect agreement with symmetry based analyses, and it allows predicting the sequence of synchronized clusters which form before the eventual occurrence of global synchronization.

description: In the present letter we suggest a new model of preons-dyons making composite quark-leptons and bosons, described by the supersymmetric string-inspired flipped E_6\times \tilde E_6 gauge group of symmetry. This investigation predicts the possible extension of the Standard Model to the Family replicated gauge group model of type G^{N_{fam}}, where N_{fam} is the number of families. Here E_6 and \tilde E_6 are non-dual and dual sectors of theory with hyper-electric g and hyper-magnetic \tilde g charges, respectively. Our model is based on the recent theory of composite non-Abelian flux tubes in SQCD. Considering the breakdown of E_6 (and \tilde E_6) at the Planck scale into the SU(6)\times U(1) gauge group, we have shown that the six types of composite N = 1 supersymmetric non-Abelian flux tubes are created by the condensation of spreons-dyons near the Planck scale and have fluxes quantized according to the Z_6 center group of SU(6): Φ_n = nΦ_0 (n = \pm 1,\pm 2,\pm 3). These fluxes give three types of k-strings with tensions T_k = kT_0, where k = 1,2,3, and produce three generations of composite quark-leptons and bosons. Thus, the present model predicts N_{gen} = N_{fam} = 3. The condensation of spreons near the Planck scale gives the phase transition at scales M_{crit} and \tilde M_{crit}, and we have calculated the critical values of gauge coupling constants.

description: We consider QCD radiative corrections to the associated production of a heavy-quark pair ($Q{\bar Q}$) with a generic colourless system $F$ at hadron colliders. We discuss the resummation formalism for the production of the $Q{\bar Q}F$ system at small values of its total transverse momentum $q_T$. The perturbative expansion of the resummation formula leads to the explicit ingredients that can be used to apply the $q_T$ subtraction formalism to fixed-order calculations for this class of processes. We use the $q_T$ subtraction formalism to perform a fully differential perturbative computation for the production of a top-antitop quark pair and a Higgs boson. At next-to-leading order we compare our results with those obtained with established subtraction methods and we find complete agreement. We present, for the first time, the results for the flavour off-diagonal partonic channels at the next-to-next-to-leading order.

description: We obtain the light meson mass spectroscopy from the light-front quantum chromodynamics (QCD) Hamiltonian, determined for their constituent quark-antiquark and quark-antiquark-gluon Fock components, together with a three-dimensional confinement. The eigenvectors of the light-front effective Hamiltonian provide a good quality description of the pion electromagnetic form factor, decay constant, and the valence quark distribution functions following QCD scale evolution. We also show that the pion's gluon densities can be probed through the pion-nucleus induced $J/ψ$ production data. Our pion parton distribution functions provide excellent agreement with $J/ψ$ production data from widely different experimental conditions.

description: We present distance estimates for eleven peculiar Virgo cluster spiral galaxies based on measurements of the stellar kinematics of their central 2 kpc. Stellar circular velocities were obtained using two-integral dynamical models. Distances were obtained by comparing, at each radius, the stellar circular velocities with synthetic H_alpha rotation curves derived from NIR Tully-Fisher relations.The results show that most of our galaxies are located within 4 Mpc of the core of the cluster. Three of these galaxies, previously classified as "low rotator galaxies" or with "Truncated/Compact" H_alpha radial distributions, have stellar kinematics-based distances that are discrepant with HI-based distances by at least 60%, and are likely to be located within the virial radius of the cluster. These discrepancies appear due to very truncated gas distributions plus non-circular gas motions or gas motions not in the plane of the stellar disk, perhaps as the result of gravitational interactions. Our results show that environmental effects can significantly reduce the measured HI linewidths for some disturbed cluster galaxies, thus affecting the accurate determination of distances based on gas kinematics methods.
