Oh, the Places [I'll] Go! Identity, Possible Selves, and Role Changes in Social Movements
Creators: name: Horowitz, Jonathan
Publisher: name: University of North Carolina at Chapel Hill
Year: 2012

description: Preparation for life course transitions begins before the actual event occurs, and individuals use possible selves to map out potential courses of action. Meanwhile, social movements scholars are increasingly using identity as a theoretical construct, but most research in this area uses social psychology ad hoc without building from existing theory. The present study builds from research on the possible self and identities at a life course transition. The study demonstrates the variation in activist identities by background and time horizon and the identity work that graduating student activists use to construct activist identities. The quantitative results demonstrate that the strength of the possible activist identity varies by sex, race/ethnicity, feminist cause affiliation, and time horizon. The qualitative results show that collective memory of past social movement struggles and exposure to feminist ideology produce markedly different types of activist identities, explaining much of the variation identified in the quantitative results.

description: Non-linearity of the current-phase relationship of a Josephson junction is the key resource for a Josephson parametric amplifier (JPA), the only device in which the quantum limit has so far been achieved at microwave frequencies. A standard approach to describe JPA takes into account only the lowest order (cubic) non-linearity resulting in a Duffing-like oscillator equation of motion or in a Kerr-type non-linearity term in the Hamiltonian. In this paper we derive the quantum expression for the gain of JPA including all orders of the Josephson junction non-linearity in the linear response regime. We then analyse gain saturation effect for stronger signals within semi-classical approach. Our results reveal non-linear effects of higher orders and their implications for operation of a JPA.

description: We report lifetime measurements of the 6 levels in the 3d6(5D)4d e6G term in Fe ii at an energy of 10.4 eV, and f -values for 14 transitions from the investigated levels. The lifetimes were measured using time-resolved laser-induced fluorescence on ions in a laser-produced plasma. The high excitation energy, and the fact that the levels have the same parity as the the low-lying states directly populated in the plasma, necessitated the use of a two-photon excitation scheme. The probability for this process is greatly enhanced by the presence of the 3d6(5D)4p z6F levels at roughly half the energy difference. The f -values are obtained by combining the experimental lifetimes with branching fractions derived using relative intensities from a hollow cathode discharge lamp recorded with a Fourier transform spectrometer. The data is important for benchmarking atomic calculations of astrophysically important quantities and useful for spectroscopy of hot stars.

description: First-principles density functional theory (DFT) study of embedding V and Nb atom in monovacant and divacant graphene is reported. Complete/almost complete spin polarization is verified for V/Nb embedding in MV/DV graphene. The origin of magnetism has been identified via interaction of 3d-states of embedded trnasition metal atom with p-states of inequivalent C atoms present in the vicinity of embedding site. Band structure analysis has been performed to address the semiconducting behavior of graphene in minority spin channel on embedding V/Nb atom. The isosurface plots also confirm the magnetic nature of present nanosystems. Our results reveal that these nanosystems have potential for futuristic applications such as spintronics, energy resources and high frequency transistors.

Enactment and retrieval
Creators: name: Peterson, Daniel J.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2009

description: A number of memory phenomena are modulated by experimental design, with the effect (e.g. of bizarreness, generation, perceptual interference) occurring in recall for mixed-list but not pure-list designs. These effects have other similarities and have been treated in common theoretical frameworks, some focusing on encoding others on retrieval. The typical paradigm for examining design effects confounds encoding and retrieval contexts, making it difficult to compare these accounts. McDaniel et al. (2005), using a new paradigm, concluded that retrieval processes contribute to the bizarreness effect. This paradigm was applied to the related enactment effect. Participants were presented with two pure study lists, and later recalled the lists separately (inducing pure retrieval sets) or recalled the lists together in a single test (inducing a combined or mixed retrieval set). In three experiments, the combined recall condition consistently failed to enhance the size of the enactment effect. The results provide no support for the retrieval account of these two variables but are generally consistent with encoding accounts.

Post-coronagraphic tip-tilt sensing for vortex phase masks: the QACITS technique

description: Small inner working angle coronagraphs, like the vortex phase mask, are essential to exploit the full potential of ground-based telescopes in the context of exoplanet detection and characterization. However, the drawback of this attractive feature is a high sensitivity to pointing errors, which degrades the performance of the coronagraph. We propose a tip-tilt retrieval technique based on the analysis of the final coronagraphic image, hereafter called Quadrant Analysis of Coronagraphic Images for Tip-tilt Sensing (QACITS). Under the assumption of small phase aberrations, we show that the behaviour of the vortex phase mask can be simply described from the entrance pupil to the Lyot stop plane by Zernike polynomials. This convenient formalism is used to establish the theoretical basis of the QACITS technique. Simulations have been performed to demonstrate the validity and limits of the technique, including the case of a centrally obstructed pupil. The QACITS technique principle is further validated by experimental results in the case of an unobstructed circular aperture. The typical configuration of the Keck telescope (24% central obstruction) has been simulated with additional high order aberrations. In these conditions, our simulations show that the QACITS technique is still adapted to centrally obstructed pupils and performs tip-tilt retrieval with a precision of $5 \times 10^{-2}$ λ/D when wavefront errors amount to λ/14 rms and $10^{-2}$ λ/D for λ/70 rms errors (with λ the wavelength and D the pupil diameter). The implementation of the QACITS technique is based on the analysis of the scientific image and does not require any modification of the original setup. Current facilities equipped with a vortex phase mask can thus directly benefit from this technique to improve the contrast performance close to the axis.

description: Forest matters have exploded onto the public scene in British Columbia once again, even if they never really went anywhere after the turbulence of the War in the Woods. Struggles to protect old-growth forests and an industry push for access to these same forests are entangled with the exercise of Indigenous Jurisdiction, Rights, and Title to forest lands and a government focused on containing conflicts while remaining wedded to an extractive agenda. While a vibrant academic debate assessed past tensions in the woods until the early 2000s, there has been a noticeable downturn in forestry research since then. This article assesses the contours of past academic debates on forestry and asks why researchers lost the plot in the forests. The cool down of conflicts in the woods is one answer; the increasing focus on oil and gas is another. Reflecting on past debates and changes in the political economy and coloniality of the forestry sector, I highlight past silences in the literature and the new dynamics in the forested landscapes of the province. I do so by drawing on my collaborative research investigating the uneasy interweaving of so-called “private forest lands,” finance capital, and Indigenous Rights and Title on Vancouver Island. The hope is that this small intervention will be part of a bigger wave of research to come that will help to unpack the complicated political mosaic of British Columbia’s forestry sector.

description: Despite the mounting scale of reforestation work in response to extensive deforestation and accelerating climate change, the tree planting industry in British Columbia is under-regulated and understudied. Industry leaders admit that prevalent and pervasive sexism is an issue, and recent reporting has indicated that widespread sexual assault and harassment are endemic to the field. A feminist analysis of the gendered power dynamics of tree planting is necessary in order to understand how these harms might be remedied. Through semi-structured interviews with industry actors, particularly with women and gender-diverse tree planters who have experienced gender-based violence in BC planting camps, our research investigates various solutions proposed by research participants, demonstrating how listening to survivors can help shape environments that are freer from harm. The primary solutions offered by interviewees were: (1) the development of company anti-violence policies and procedural follow-through; (2) an intentional increase in gender representation among industry leadership; and (3) increased anti-oppression training for all, but especially for management. Company-level solutions were experienced as the most straightforward place to begin imagining change, as this change and its impacts could be immediate and significant for the survivors with whom we spoke as well as for future planters. Despite this, it is difficult to imagine robust solutions happening voluntarily across all tree planting companies without external oversight. We hope that future research will investigate how regulatory incentives or government interventions might increase company accountability and solutions-implementation in a manner that is sensitive to the industry’s unique labour conditions.

The Politics of Public History in the Fraser Valley, the Tretheweys of Abbotsford, and Legacies of White Supremacy
Creators: name: Rocksborough-Smith, Ian
Publisher: name: BC Studies: The British Columbian Quarterly
Year: 2023

description: This research note is based on the experiences of a former Heritage Abbotsford Society Board Member (2018-2021). It critically reflects on the politics of public history, related to ongoing representations of the Trethewey family in the City of Abbotsford, B.C.'s public place names and heritage sites. It argues that public revelations about the association of the family to the emergence of the Ku Klux Klan in the town during the 1920s needs to be better represented and critically reflected upon in representations of local pasts, especially in light of recent movements against institutional racism and for truth and reconciliation. Based in part on one presentation from a panel at BC Studies at the Unviersity of the Fraser Valley in May of 2021, this research note suggests future research is needed to undcover more local histories of white supremacy and racism in the Fraser Valley. Futher work is needed to understand the ways these histories intersect and engage with the past and present politics of doing public-facing historical work in a country increasingly reckoning with its racist pasts.

Legislated Wage Suppression
Creators: name: Fairey, David
Publisher: name: BC Studies: The British Columbian Quarterly
Year: 2023

description: The regulation of agricultural labour has been the subject of policy debate and controversy in BC for several decades without resolution. At issue has been whether fruit and vegetable farming can sustain an end to the discriminatory exclusion of farm workers from certain employment rights and protections provided by regulation to most other workers in the province. The BC government has resisted implementing the 2018 recommendations of its Fair Wage Commission with respect to ending the exclusion of hand harvesters of fruits, berries, certain vegetables and flowers from the general hourly minimum wage provisions of the Employment Standards Act based on a concern that the economics of berry farming in the Fraser Valley of BC may not justify any different system of minimum wage regulation other than the antiquated minimum piece rate system in place since 1981 under the Employment Standards Regulation. This paper demonstrates that the government’s concern is unfounded, and that the large and important blueberry farming sector, the largest fruit growing sector, has the ability to pay its hand harvesters the hourly minimum wage. This paper also identifies three distinct features of the blueberry farming industry in BC that negatively impacts racialized recent immigrant hand harvesters: 1) farm operator reliance on for-profit farm labour contractors to directly employ and pay farm workers; 2) discriminatory exclusion from the legislated hourly minimum wage and the resulting legislated minimum wage suppression for hand harvesters; and 3) the oligopolistic control by large vertically integrated fruit processors over the volume, price, payment contracts for, and marketing of blueberries produced by a large number of farms, and makes policy recommendations to address these long standing issues.

The bulk dual gravitational theory is described by a (3+1) dimensional charged AdS black hole in the presence of a massive charged scalar field. The holographic free energy of the (2+1) dimensional strongly coupled boundary field theory is computed analytically through the bulk boundary correspondence. The thermodynamic metric and the corresponding scalar curvature is then obtained from the holographic free energy. The thermodynamic scalar curvature characterizes the superconducting phase transition of the boundary field theory.

How predictability and givenness produce activation, and acoustic reduction
Creators: name: Kahn, Jason
Publisher: name: University of North Carolina at Chapel Hill
Year: 2011

description: Speakers tend to use reduced pronunciation, e.g. shorter duration, when words are previously mentioned, or predictable in context. Existing accounts of this phenomenon underspecify whether both giveness and predictability make independent contributions, and say little about the underlying cognitive mechanism. I propose and test the Activation Reduction Hypothesis (ARH), which states that any stimulus that activates representations used for language production should elicit reduced pronunciations. This unites givenness and predictability in a single plausible psychological mechanism, and makes novel predictions, which I tested in three experiments. The first experiment shows that linguistic stimuli elicit more reduction than non-linguistic stimuli, which also elicit reduction. The second shows that linguistic stimuli elicit reduction in the absence of strong predictability, suggesting a role for sheer activation. The third attempts to isolate this reduction at the conceptual level of representation, but shows little supporting evidence.

description: We have determined the lattice dynamics of MgSiO$_3$ perovskite (bridgmanite) by a combination of single-crystal inelastic x-ray scattering and ab initio calculations. We observe a remarkable agreement between experiment and theory, and provide accurate results for phonon dispersion relations, phonon density of states and the full elasticity tensor. The present work constitutes an important milestone to extend this kind of combined studies to extreme conditions of pressure and temperature, directly relevant for the physics and the chemistry of Earth's lower mantle.

description: High frequency (ac) conductivity in the single quantum well AlGaAs/GaAs/AlGaAs with high mobility was investigated by contactless acoustic methods in the fractional quantum Hall effect regime in perpendicular and tilted magnetic fields. We studied the dependence of ac conductivity $σ^{ac}=σ_1 - iσ_2$ on both the temperature and magnetic field tilt angle. Tilting the magnetic field relative to the sample surface enabled us to change the position of the conductivity oscillation minimum at $ν$=2/3. We measured the temperature dependence of ac conductivity for each tilt angle and for the 2/3 state we calculated the activation energy $ΔE$ which was derived by constructing the Arrhenius plot ln $σ_1$ against 1/$T$. Analyzing behavior of the activation energy in total magnetic field for the filling factor 2/3 we observed a distinct minimum which can be interpreted as the spin unpolarized-polarized phase transition.

description: The magneto-photoluminescence in modulation doped core-multishell nanowires is predicted as a function of photo-excitation intensity in non-perturbative transverse magnetic fields. We use a self-consistent field approach within the effective mass approximation to determine the photoexcited electron and hole populations, including the complex composition and anisotropic geometry of the nano-material. The evolution of the photoluminescence is analyzed as a function of i) photo-excitation power, ii) magnetic field intensity, iii) type of doping, and iv) anisotropy with respect to field orientation.

description: Representing simultaneous black hole accretion during a merger, binary active galactic nuclei (AGNs) could provide valuable observational constraints to models of galaxy mergers and AGN triggering. High-resolution radio interferometer imaging offers a promising method to identify a large and uniform sample of binary AGNs, because it probes a generic feature of nuclear activity and is free from dust obscuration. Our previous search yielded 52 strong candidates of kpc-scale binaries over the 92 deg$^2$ of the Sloan Digital Sky Survey (SDSS) Stripe 82 area with 2"-resolution Very Large Array (VLA) images. Here we present 0.3"-resolution VLA 6 GHz observations for six candidates that have complete optical spectroscopy. The new data confirm the binary nature of four candidates and identify the other two as line-of-sight projections of radio structures from single AGNs. The four binary AGNs at $z \sim 0.1$ reside in major mergers with projected separations of 4.2-12 kpc. Optical spectral modeling shows that their hosts have stellar masses between $10.3 < log(M_\star/M_\odot) < 11.5$ and velocity dispersions between $120 < σ_\star < 320$ km/s. The radio emission is compact ($23^{+15}_{-8}$% of the time when a kpc-scale galaxy pair is detectable as a radio-AGN. The high duty cycle of the binary phase strongly suggests that major mergers can trigger and synchronize black hole accretion.

Immunohistochemical evaluation of sex steroid hormones in sicca syndrome patients
Creators: name: Rokos, James W.

description: Sjogren syndrome (SS) is a chronic autoimmune disease affecting mainly climacteric females. The coincidence of sex hormones decline and higher prevalence of SS in this population implies that such hormones participate in its pathogenesis. Their exact role in the pathogenesis of SS is still controversial. This study investigates the presence and location of sex hormone receptors within minor labial salivary glands (MLSG) in a cohort of sicca syndrome patients being evaluated for SS. An immunohistochemical comparison of the ratio of estrogen receptors (ER) to androgen receptors (AR) expression was correlated to the patients' focus score (FS). A greater intensity of androgen receptor expression in SS patients, especially in the nucleus of acinar cells was found when compared to the other receptors (p<0.001). However, no statistically significant difference was found in the ratio of ER to AR as a function of FS in our group of patients

description: We present calculated rate coefficients for ro-vibrational transitions of CO in collisions with H atoms for a gas temperature range of 10 K $\leq T \leq$ 3000 K, based on the recent three-dimensional ab initio H-CO interaction potential of Song et al(2013). Rate coefficients for ro-vibrational $v=1,j=0-30 \rightarrow v'=0, j'$ transitions were obtained from scattering cross sections previously computed with the close-coupling method by Song et al(2015). Combining these with the rate coefficients for vibrational $v=1-5 \rightarrow v' < v$ quenching obtained with the infinite-order sudden approximation, we propose a new extrapolation scheme that yields the rate coefficients for ro-vibrational $v=2-5,j=0-30 \rightarrow v',j'$ de-excitation. Cross sections and rate coefficients for ro-vibrational $v=2, j=0-30 \rightarrow v'=1,j'$ transitions calculated with the close-coupling method confirm the effectiveness of this extrapolation scheme. Our calculated and extrapolated rates are very different from those that have been adopted in the modeling of many astrophysical environments. The current work provides the most comprehensive and accurate set of ro-vibrational de-excitation rate coefficients for the astrophysical modeling of the H-CO collision system. Application of the previously available and new data sets in astrophysical slab models shows that the line fluxes typically change by 20-70% in high temperature environments (800 K) with an H/H$_2$ ratio of 1; larger changes occur for lower temperatures.

description: We address the question of unitary implementation of the dynamics for scalar fields in cosmological scenarios. Together with invariance under spatial isometries, the requirement of a unitary evolution singles out a rescaling of the scalar field and a unitary equivalence class of Fock representations for the associated canonical commutation relations. Moreover, this criterion provides as well a privileged quantization for the unscaled field, even though the associated dynamics is not unitarily implementable in that case. We discuss the relation between the initial data that determine the Fock representations in the rescaled and unscaled descriptions, and clarify that the S-matrix is well defined in both cases. In our discussion, we also comment on a recently proposed generalized notion of unitary implementation of the dynamics, making clear the difference with the standard unitarity criterion and showing that the two approaches are not equivalent.

A Study on Mandarin Focus Produced by English L2 Learners

subject: FOS: Languages and literature

description: This thesis investigates how Mandarin focus intonation is realized in the production of English L2 learners by examining relevant measurements of its acoustic carrier, fundamental frequency (f0), and comparing the observed results with those of the native speakers. The experiment and comparative results show that the English L2 learners are able to realize focus by manipulating duration and pitch range of the syllable accordingly. At the same time, most of the subjects are able to realize lexical tones, though not equally proficient among the four tones, instead of substituting them with a pitch accent. Result of an individual subject resolves a controversy over English focus and confirms it as a pitch accent. This thesis not only fills in a gap in the study of SLA of Mandarin intonation, but also provides pedagogical implications for L2 instruction of Mandarin.
