description: In the post-truth era, the term “bot” is used to describe automated social media accounts spreading misinformation, as well as humans acting behind “dummy” accounts. However, the ways that bots intersect with political and social discourse on social media is far more textured. Bots that generate flash fictions, text art or other pieces often intersect with the political and social discourses on Twitter in both uncomfortable and triumphant fashion.These “artbots”, unlike misinformation bots, are inherently hypermedial, always reminding the audience of their automatic nature. The ideal artbot is sincere, and the generative patterns they follow are often transparent. Consequently, these bots occupy a different space in the post-truth social media discourse. They are not malicious automations to be shut-down, nor are they human posters engaging intelligently in conversation. Artbots post indiscriminatorily: they innocently follow their patterns of generative art, resulting in poetic timings and uncomfortable collisions with Twitter’s discourse. Examples include the “Emote! at the location” Twitterbot stating “Calm down! At the protest” amid #BlackLivesMatter protests this year, igniting a discourse around emotion and social justice within the tweet’s comments.To interrogate the functions and meanings that emerge when an automation’s pattern collides with social discourses, this paper presents a visualisation of #BlackLivesMatter tweets, contrasted against artbot posts. By mapping the collisions between moments in the movement with artbot postings, our analysis explores the ethics of botmaking as creative practice, and the role of automated entities in constructing and framing post-truth political discourse as dialogue creators, rather than propogandists.
Grand Unified Yukawa Matrix Ansatz: The Standard Model Fermion Mass, Quark Mixing and CP Violation Parameters

description: We propose a new mass matrix ansatz: At the grand unified (GU) scale, the standard model (SM) Yukawa coupling matrix elements are integer powers of the square root of the GU gauge coupling constant \varepsilon \equiv \sqrt{α_{\text{GU}}}, multiplied by order unity random complex numbers. It relates the hierarchy of the SM ermion masses and quark mixings to the gauge coupling constants, greatly reducing the SM parameters, and can give good fitting results of the SM fermion mass, quark mixing and CP violation parameters. This is a neat but very effective ansatz.

description: The following paper is based on the text of a postcard sent during the Venice Biennial of 2019 which arrived at my home in the Antipodes a year later at the height of The Virus. On a planet in which technology appears to have completely outstripped the creative capacities of the human being, we must face an important question: is Contemporary Art obsolete? Being stung by a bee would be far more enlightening. This paper will argue that while “Contemporary Art” may disappear, aesthetics understood as a “science of the beautiful”, is well and truly alive.I will begin with an investigation of the term and practise of “New Media Art”, focusing specifically on two works exhibited at the 2019 Venice Biennial. These works, Interesting World (2019) by Fei Jun and I Can’t Help Myself (2019) by Sun Yuan & Peng Yu are emblematic of the spectacular use of digital technologies, namely algorithmic composition and automated intelligence. These works, as enchanting as they are, remain subject to the planned obsolescence built into the ‘contemporary’ blockbuster show.I will then draw on three works in archaic media forms, namely the aphoristic philosophical text Pollen (1798) by Novalis, the painting An Old Bee Farm (1900) by Clara Southern and the speculative science fiction novel The Glass Bees (1957) by Ernst Jünger. All three artworks consider technology and art as coevolutionary processes which can foster and stimulate creativity. In order to follow Novalis in his call to “scatter seeds…[and] pollinate the Earth” we must finally abandon the dead name of “Contemporary Art” in order for the science of the aesthetic to bloom once more in places we have ceased to look and in a buzzing we have forgotten how to hear.

description: During the first half of main-sequence lifetimes, the evolution of rotation and magnetic activity in solar-type stars appears to be strongly coupled. Recent observations suggest that rotation rates evolve much more slowly beyond middle-age, while stellar activity continues to decline. We aim to characterize this mid-life transition by combining archival stellar activity data from the Mount Wilson Observatory with asteroseismology from the Transiting Exoplanet Survey Satellite (TESS). For two stars on opposite sides of the transition (88 Leo and $ρ$ CrB), we independently assess the mean activity levels and rotation periods previously reported in the literature. For the less active star ($ρ$ CrB), we detect solar-like oscillations from TESS photometry, and we obtain precise stellar properties from asteroseismic modeling. We derive updated X-ray luminosities for both stars to estimate their mass-loss rates, and we use previously published constraints on magnetic morphology to model the evolutionary change in magnetic braking torque. We then attempt to match the observations with rotational evolution models, assuming either standard spin-down or weakened magnetic braking. We conclude that the asteroseismic age of $ρ$ CrB is consistent with the expected evolution of its mean activity level, and that weakened braking models can more readily explain its relatively fast rotation rate. Future spectropolarimetric observations across a range of spectral types promise to further characterize the shift in magnetic morphology that apparently drives this mid-life transition in solar-type stars.

description: We present precise optical and near-infrared ground-based photometry of two Globular Clusters (GCs): Omega Cen and 47 Tuc. These photometric catalogs are unbiased in the Red Giant Branch (RGB) region close to the tip. We provide new estimates of the RGB tip (TRGB) magnitudes--m_I(TRGB)=9.84+/-0.05, Omega Cen; m_I(TRGB)=9.46+/-0.06, 47 Tuc--and use these to determine the relative distances of the two GCs. We find that distance ratios based on different calibrations of the TRGB, the RR Lyrae stars and kinematic distances agree with each other within one sigma. Absolute TRGB and RR Lyrae distance moduli agree within 0.10--0.15 mag, while absolute kinematic distance moduli are 0.2--0.3 mag smaller. Absolute distances to 47 Tuc based on the Zero-Age-Horizontal-Branch and on the white dwarf fitting agree within 0.1 mag, but they are 0.1--0.3 mag smaller than TRGB and RR Lyrae distances.

The influence of intraorganizational conflict upon the behaviour of a collective bargaining team
Creators: name: Storey, Gordon Douglas
Publisher: name: University of British Columbia
Year: 2010

description: This thesis reports theory development and explorative field observation of potential effects of conflict occurring within a collective bargaining team. From the theoretical bases of Walton and McKersie's (1965) intraorganizational conflict (IOC) concept and Pondy's (1967) process model of conflict, a model of bargaining team IOC is developed. The model partitions bargaining team IOC into functional and dysfunctional subsets. Seven propositions related to the effects of dysfunctional IOC are developed from conflict and decision making literature. These propositions are concerned with the effects of dysfunctional IOC on participation of team members, rule breaking behavior, time delays, and decision styles. Operational definitions and tests for dysfunctional IOC are developed using Filley's (1975) five item definition of conflict and seven item win-lose, lose-lose, conflict responses. A participant/observer quasi-case analysis of an actual collective bargaining team experience is the basis for data generation. Many of the propositions are supported iii the observed bargaining team environment. While the single case methodology prevents generalized conclusions regarding the effects of dysfunctional IOC, the findings tentatively suggest there may be considerable practical payoffs for extending this research area. The field experience provides some additional research insights regarding the dynamic variable of dysfunctional IOC. In this study, dysfunctional bargaining team IOC is observed as a few recurring issue-related problems flowing throughout the bargaining team interactions. Implications of this study regarding future research on IOC in a bargaining team are suggested.

description: In 1810 Kleist wrote ‘And Paradise is locked and bolted, with the cherub behind us; we must journey around the world and determine if perhaps at the end somewhere there is an opening to be discovered again’. In this presentation I pick the lock to the backdoor, to the place that Kleist calls Paradise. The question which underlies my proposition, whether an exploration of the backdoor – and the ‘en abyme’ within it as distinct artistic phenomenon has anything to offer us when we think about the concept of the Dark Eden. This idea about gaining access to a shadow zone, a spectral zone, a closed system through a ‘backdoor’ is a meta-narrative function of mise en abyme which interests me when considering its uses, a reflection of what is outside the realm, which helps to contextualise and explain what is within it. In the case it nominates a realm which lies under the shadow of, but is still, for the moment, outside of codification. Opened to the possibility of the backdoor entrance which I am speculating is ‘the antipode of the antipodes’ (Flanagan 2002), Kleist informs us to find a method that bypasses normal authentication. To take a journey, find the hidden back door with fellow travelers, elsewhere and leave behind the cherubim, and instead embrace the escutcheoned, the imperiled, the undaunted, the gamblers, and inspired chancers. Revealed concealed processes I am opening us to an archaeology of leaky promiscuous earth simulations and geo-logic filtering, endorsing nascent understandings dark symbolic mirrors.

description: When circularly polarized light interacts with a nanostructure, the optical response depends on the geometry of the structure. If the nanostructure is chiral (i.e., it cannot be superimposed on its mirror image), then its optical response, both in near-field and far-field, depends on the handedness of the incident light. In contrast, achiral structures exhibit identical far-field responses for left- and right-circular polarization. Here, we show that a perfectly achiral nanostructure, a plasmonic metamolecule with trigonal D3h symmetry, exhibits a near-field response that is sensitive to the handedness of light. This effect stems from the near-field interference between the different plasmonic modes sustained by the plasmonic metamolecule under circularly polarized light excitation. The local chirality in a plasmonic trimer is then experimentally evidenced with nanoscale resolution using a molecular probe. Our experiments demonstrate that the optical near-field chirality can be imprinted into the photosensitive polymer, turning an optical chirality into a geometrical chirality that can be imaged using atomic force microscopy. These results are of interest for the field of polarization-sensitive photochemistry.

description: We investigate the chiral phase transition in the strong coupling lattice QCD (SC-LQCD) at finite temperature and density with finite coupling effects. We adopt one species of staggered fermion, and develop an analytic formulation based on strong coupling and cluster expansions. We derive the effective potential as a function of two order parameters, the chiral condensate sigma and the vector potential ω_τ, in a self-consistent treatment of the next-to-leading order (NLO) and the next-to-next-to-leading order (NNLO) effective action terms. Finite coupling effects lead to modifications of quark mass, chemical potential and the quark wave function renormalization factor. Finite coupling effects suppress the critical temperature at mu=0 (T_{c,mu=0}), while critical temperature at T=0 (mu_{c,T=0}) is not affected much. NNLO corrections does not significantly affect T_{c,mu=0} and mu_{c,T=0}, but the phase diagram shape including the position of the critical point is sensitive to the NNLO effects. Partially chiral restored matter is found to exist in NLO and NNLO SC-LQCD.

description: Non-Hermitian systems with specific forms of Hamiltonians can exhibit novel phenomena. However, it is difficult to study their quantum thermodynamical properties. In particular, the calculation of work statistics can be challenging in non-Hermitian systems due to the change of state norm. To tackle this problem, we modify the two-point measurement method in Hermitian systems. The modified method can be applied to non-Hermitian systems which are Hermitian before and after the evolution. In Hermitian systems, our method is equivalent to the two-point measurement method. When the system is non-Hermitian, our results represent a projection of the statistics in a larger Hermitian system. As an example, we calculate the work statistics in a non-Hermitian Su-Schrieffer-Heeger model. Our results reveal several differences between the work statistics in non-Hermitian systems and the one in Hermitian systems.

description: This paper positions the pineapple as a metaphor of a transcultural traveller through revisiting Ortiz’s (1947) neologism of cultural appropriation and linguist Pratt’s (1992) focus on ‘transculturation’ which is through travel writing produced within the space of contact. It extends the definition of transculturation by contextualising it through ideas surrounding authenticity, appropriation and displacement and investigates to what extent transculturation is a process of art-making itself by drawing on the materiality of the subject to address current ideas on new materialism in which the materiality of the world is transformed through physical and digital contact.By considering the expanded image through the lens of Art in relation to a definition of Contemporary beyond ‘the West and the rest”, I argue that the power invested in transcultural processes is that the artworld’s constraining structures are largely absent, and images unmoored from artworld preconceptions and as a cultural material formed by an intermeshing of cultures, operate largely in their own space.One example is the syncretic conflation of indigenous Animism with Christianity is the collapsing of the image of the pineapple into the figure of the Christ Child in the Philippines; similarly, the European merging of the Tupi name ‘Nana’ for the pineapple (Levitt 2014) was due to its resemblance to a pine cone. Such conflations demonstrate that ‘the transcultural dynamic is directly proportional to the limits and opacity of its translation’ (McLean 2014). Contact produces misunderstandings and mistranslations, but these can be fruitful.

Frequency analysis of Cepheids in the Large Magellanic Cloud. New types of classical Cepheid pulsators

description: We have performed a detailed systematic search for multiperiodicity in the Population I Cepheids of the Large Magellanic Cloud. In this process we have identified for the first time several new types of Cepheid pulsational behaviour. We have found two triple-mode Cepheids pulsating simultaneously in the first three radial overtones. In 9% of the first overtone Cepheids we have detected weak, but well resolved secondary periodicities. They appear either very close to the primary pulsation frequency or at a much higher frequency with a characteristic period ratio of 0.60-0.64. In either case, the secondary periodicities must correspond to nonradial modes of oscillation. This result presents a major challenge to the theory of stellar pulsations, which predicts that such modes should not be exited in Cepheid variables. Nonradial modes have also been found in three of the fundamental/first overtone double-mode Cepheids, but no such oscillations have been detected in single mode Cepheids pulsating in the fundamental mode. In 19% of double-mode Cepheids pulsating in the first two radial overtones (FO/SO type) we have detected a Blazhko-type periodic modulation of amplitudes and phases. Both modes are modulated with a common period, which is always longer than 700 days. Variations of the two amplitudes are anticorrelated and maximum of one amplitude always coincides with minimum of the other. We have compared observations of modulated FO/SO Cepheids with predictions of theoretical models of the Blazhko effect, showing that currently most popular models cannot account for properties of these stars. We propose that Blazhko effect in FO/SO Cepheids can be explained by a nonstationary resonant interaction of one of the radial modes with another, perhaps nonradial, mode of oscillations.

description: Here we use global and local magnetometry and Hall probe imaging to investigate the electromagnetic connectivity of the superconducting current path in the oxygen-deficient fluorine-free Nd-based oxypnictides. High resolution transmission electron microscopy and scanning electron microscopy show strongly-layered crystallites, evidence for a ~ 5nm amorphous oxide around individual particles, and second phase neodymium oxide which may be responsible for the large paramagnetic background at high field and at high temperatures. From global magnetometry and electrical transport measurements it is clear that there is a small supercurrent flowing on macroscopic sample dimensions (mm), with a lower bound for the average (over this length scale) critical current density of the order of 103 A/cm2. From magnetometry of powder samples and local Hall probe imaging of a single large conglomerate particle ~120 microns it is clear that on smaller scales, there is better current connectivity with a critical current density of the order of 5 x 104 A/cm2. We find enhanced flux creep around the second peak anomaly in the magnetisation curve and an irreversibility line significantly below Hc2(T) as determined by ac calorimetry.

We follow the spirit of the canonical ensemble approach. We consider the system under study as embedded in a far larger total system. We explore some of the consequences that such an embedding has, if it is modelled by a Riemannian submersion. We point out the significance in such a description of the finite-dimensional Bakry-Émery Ricci tensor, as a local mesoscopic invariant, for understanding the collective dynamical behavior of systems described by the $q$-entropies.

description: Technologies of speed, penetration and compression now enable images to be created, stored, mined, circulated and erased in new ways. Discoveries from astronomy to geology and computing expand human horizons while programmes of extractivism are prolonged in material, social and psychic worlds. The regime of data visualization that fuels contemporary science and markets alike naturalizes its authority over the representation of the present and the collective vision of species’ pasts and futures. Restrictions on our physical mobility and social habits in the current conditions of the pandemic confirm the vulnerability of our perceptual systems but also their capacity to transform.This paper envisages time beyond the exhausting and entropic image regimes that drive dominant forms of industrial and networked modernity. It does so through a series of studies of visual artworks featured in exhibitions that I have staged as artist-curator and initiator of The Habitat of Time (2018-). This international research project explores rapids shifts in our experience of time produced by the current conditions of unstable globalization. The durational, digital, sculptural and installation artworks explored in this paper have been presented at Arts Catalyst London (2020), Casula Powerhouse, Liverpool NSW (2018) and Artspace Sydney (2017). They demonstrate the ways in which artists conceive of new matterings of the image through their transdisciplinary research and speculative practice at the intersection of art, science and technology. In this expanded field, images show up as entanglements of material, social and perceptual forces, conveying the interdependency of human and more-than-human worlds.

The Crowsnest Pass rates: an evaluation of policy alternatives
Creators: name: Watson, Karen Gail
Publisher: name: University of British Columbia
Year: 2010

description: The Crowsnest Pass rates are fixed rail freight rates that apply on the carriage of most Canadian grain. They were originally established in 1897, and have been embodied in Federal statute since 1925. In recent years, the rates have covered less than 40 percent of rail-grain costs. With continuing cost inflation, this proportion will decrease to even lower levels over time. Several policy alternatives are available to the Federal Government with respect to the transportation of grain by rail. These alternatives are characterized primarily by different freight rate levels. The lowest rate level considered herein is the current one; the highest is a level at which the railways would recover the long-run variable costs of the rail-grain system plus a contribution to their constant costs. For each price-level alternative, there are a range of subsidy alternatives. Depending on the particular price level, subsidies could be given to the railways, the grain producers, neither of these, or both of them. In order to evaluate the policy alternatives, there must be criteria for evaluation. The criteria used in this thesis are the major objectives that relate to the issue. Two of the objectives are to improve economic efficiency and to facilitate the development of secondary industry in the Prairie provinces. Both of these objectives favour the pricing alternative of raising grain freight rates to a compensatory level. Without producer subsidies, however, this alternative violates a third objective--that of minimizing grain-producer transportation costs. In addition to these three objectives, there are four objectives that refer particularly to the Federal Government. They are maximizing votes, implementing the "user pay" philosophy, minimizing total subsidy payments, and assisting railway variable-cost recovery in grain transport. A major consideration that is not an objective is the resistance of producers to direct, rather than indirect, subsidies. The quantitative impacts of raising rail-grain rates on the railways and on grain producers are substantial. Implementing rail freight rates equal to the long-run variable costs of transporting grain would have increased the combined net revenue of the Canadian National Railways and CP Rail by at least two-thirds in 1976. It would have decreased the net income of Prairie grain farms by (at most) 15 percent in the same year. Two policy alternatives are chosen as the better alternatives. The first policy selected is that of initial Crowsnest Pass rates, increasing over time to a larger and larger proportion of rail-grain costs. This pricing scheme would be accompanied by constant railway subsidies to reflect the difference between costs and revenues. The second policy is an immediate increase to rates covering variable costs, with subsequent annual increases to adjust for inflation. With this pricing policy, there would be constant producer subsidies equal to the initial rate increase.

description: Recently, a new family of integrators (Hamiltonian Boundary ValueMethods) has been introduced, which is able to precisely conserve the energy function of polynomial Hamiltonian systems and to provide a practical conservation of the energy in the non-polynomial case. We settle the definition and the theory of such methods in a more general framework. Our aim is on the one hand to give account of their good behavior when applied to general Hamiltonian systems and, on the other hand, to find out what are the optimal formulae, in relation to the choice of the polynomial basis and of the distribution of the nodes. Such analysis is based upon the notion of extended collocation conditions and the definition of discrete line integral, and is carried out by looking at the limit of such family of methods as the number of the so called silent stages tends to infinity.

description: Motivated by recent work suggesting observably large spacetime fluctuations in the causal development of an empty region of flat space, we conjecture that these metric fluctuations can be quantitatively described in terms of a conformal field theory of near-horizon vacuum states. One consequence of this conjecture is that fluctuations in the modular Hamiltonian $ΔK$ of a causal diamond are equal to the entanglement entropy: $\langle ΔK^2 \rangle = \langle K \rangle = \frac{A(Σ_{d-2})}{4 G_d}$, where $A(Σ_{d-2})$ is the area of the entangling surface in $d$ dimensions. Our conjecture applies to flat space, the cosmological horizon of dS, and AdS Ryu-Takayanagi diamonds, but not to large finite area diamonds in the bulk of AdS. We focus on three pieces of quantitative evidence, from a Randall-Sundrum II braneworld, from the conformal description of black hole horizons, and from the fluid-gravity correspondence. Our hypothesis also suggests that a broader range of formal results can be brought to bear on observables in flat and dS spaces.

description: The suite of highly confined polaritons supported by two-dimensional (2D) materials constitutes a versatile platform for nano-optics, offering the means to channel light on deep-subwavelength scales. Graphene, in particular, has attracted considerable interest due to its ability to support long-lived plasmons that can be actively tuned via electrical gating. While the excellent optoelectronic properties of graphene are widely exploited in plasmonics, its mechanical flexibility remains relatively underexplored in the same context. Here, we present a semi-analytical formalism to describe plasmons and other polaritons supported in waveguides formed by bending a 2D material into a parabolic shape. Specifically, for graphene parabolas, our theory reveals that the already large field confinement associated with graphene plasmons can be substantially increased by bending an otherwise flat graphene sheet into a parabola shape, thereby forming a plasmonic waveguide without introducing potentially lossy edge terminations via patterning. Further, we show that the high field confinement associated with such channel polaritons in 2D parabolic waveguides can enhance the spontaneous emission rate of a quantum emitter near the parabola vertex. Our findings apply generally to 2D polaritons in atomically thin materials deposited onto grooves or wedges prepared on a substrate or freely suspended in a quasi-parabolic (catenary) shape. We envision that both the optoelectronic and mechanical flexibility of 2D materials can be harnessed in tandem to produce 2D channel polaritons with versatile properties that can be applied to a wide range of nano-optics functionalities, including subwavelength polaritonic circuitry and bright single-photon sources.

description: We employ a high-resolution Köppen climate classification dataset to examine shifts in Tundra zones within the Alps and Asia. Our analysis shows substantial reductions in Tundra areas by the mid-21st century under different Shared. Socioeconomic pathways (SSP1-2.6, SSP3-7.0, SSP5-8.5). Tundra zones in the Alps and the Tibetan Plateau are crucial for their unique climates and role as water reservoirs. Characterized by short, mild summers and long, severe winters, these zones are vital for the glaciers and perennial snow. The projected climate instability may significantly reduce alpine snow cover by mid-century with irreversible consequences. A 2C temperature increase from the 1981–2010 baseline could eliminate the Tundra climate in the Alps and reduce it by over 70% in Asia. This is particularly concerning given that rivers from the Tibetan Plateau sustain nearly 40% of the global population.

description: Spin parameters of stellar-mass black holes in X-ray binaries are currently being estimated by fitting the X-ray continuum spectra of their accretion disk emission. For this method, it is necessary to know the inclination of the X-ray-producing inner region of the disk. Since the inner disk is expected to be oriented perpendicular to the spin axis of the hole, the usual practice is to assume that the black hole spin is aligned with the orbital angular momentum vector of the binary, and to estimate the inclination of the latter from ellipsoidal modulations in the light curve of the secondary star. We show that the inclination of the disk can be inferred directly if we have both spectral and polarization information on the disk radiation. The predicted degree of polarization varies from 0% to 5% as the disk inclination changes from face-on to edge-on. With current X-ray polarimetric techniques the polarization degree of a typical bright X-ray binary could be measured to an accuracy of 0.1% by observing the source for about 10 days. Such a measurement would constrain the disk inclination to within a degree or two and would significantly improve the reliability of black hole spin estimates. In addition, it would provide new information on the tilt between the black hole spin axis and the orbital rotation axis of the binary, which would constrain any velocity kicks experienced by stellar-mass black holes during their formation.
