description: We derive exact analytical results for the wave functions and energies of harmonically trapped two-component Bose-Einstein condensates with weakly repulsive interactions under rotation. The isospin symmetric wave functions are universal and do not depend on the matrix elements of the two-body interaction. The comparison with the results from numerical diagonalization shows that the ground state and low-lying excitations consists of condensates of p-wave pairs for repulsive contact interactions, Coulomb interactions, and the repulsive interactions between aligned dipoles.

description: African Americans and other people of color seek redress for their racial injuries. However, if we are living in a post-racial society, one that is blind to race, then widespread redress makes no sense since widespread discrimination allegedly is a thing of the past. Therefore, it is worth asking, "if racial justice is about remembering racial injury, ha[s] our law made that memory impossible, erased by official color-blindness?" This question has been central to the study of law among Critical Race theorists since Critical Race Theory's (CRT) inception. Therefore, an analytical convergence of CRT and Marxism should help disentangle the morass that is antidiscrimination law. The connection between Marxism and CRT can be appreciated by examining the limitations of civil rights laws in alleviating some of the most pressing social and political stresses on communities of color today. And yet, the connection seems to get lost beneath the din of those who claim that we are experiencing our first post-racial moment in a larger post-Marxist epoch. The aim of this Essay is to examine how a convergence of Marxism and CRT might enhance a critique of the U.S. Supreme Court's interpretation of race discrimination under Title VII of the 1964 Civil Rights Act.

description: Saturn's diffuse E ring consists of many tiny (micron and sub-micron) grains of water ice distributed between the orbits of Mimas and Titan. Various gravitational and non-gravitational forces perturb these particles' orbits, causing the ring's local particle density to vary noticeably with distance from the planet, height above the ring-plane, hour angle and time. Using remote-sensing data obtained by the Cassini spacecraft in 2005 and 2006, we investigate the E-ring's three-dimensional structure during a time when the Sun illuminated the rings from the south at high elevation angles (> 15 degrees). These observations show that the ring's vertical thickness grows with distance from Enceladus' orbit and its peak brightness density shifts from south to north of Saturn's equator plane with increasing distance from the planet. These data also reveal a localized depletion in particle density near Saturn's equatorial plane around Enceladus' semi-major axis. Finally, variations are detected in the radial brightness profile and the vertical thickness of the ring as a function of longitude relative to the Sun. Possible physical mechanisms and processes that may be responsible for some of these structures include solar radiation pressure, variations in the ambient plasma, and electromagnetic perturbations associated with Saturn's shadow.

description: For the model of a linearly driven quantum anharmonic oscillator, the role of damping is investigated. We compare the position of the stable points in phase space obtained from a classical analysis to the result of a quantum mechanical analysis. The solution of the full master equation shows that the stable points behave qualitatively similar to the classical solution but with small modifications. Both the quantum effects and additional effects of temperature can be described by renormalizing the damping.

description: This study examines the relationship between criminal justice involvement and high-risk sexual partnerships among a random sample of 416 women in methadone treatment in New York City. Logistic regression models were used to estimate the associations between recent criminal justice involvement (arrest or incarceration in the past 6 months) and recent high-risk partnerships (multiple sex partners, sex trading, or sex with a risky partner in the past 6 months) when adjusting for sociodemographic factors and recent regular drug use. Women with recent criminal justice involvement demonstrated higher odds of engaging in high-risk sex partnerships. Although regular drug use was a significant confounder of several of these relationships, recent arrest or incarceration remained significantly associated with multiple sex partnerships, sex with a risky partner, and engaging in unprotected sex and a high-risk partnership even after controlling for regular drug use and other social stressors. This study highlights the vulnerability of drug-involved women offenders to human immunodeficiency virus (HIV) risk and points to the need for investigation into the role of arrest and incarceration as factors that may contribute to HIV infection.

description: Objectives The objective of the research was to explore the possible relationships of commonly used pain measures in women suffering from vulvar pain. Methods Characterization of the pain profiles of a twenty women cohort presenting with vulvar pain was undertaken. Descriptive analysis was used to describe the cohort. Scatter plots were used to explore the relationships between the vulvalgesiometer pain thresholds, the McGill Pain Questionnaire responses and modified visual analogue scale scores. Spearman 's correlation coefficient of Rho greater than eight was considered important. Results The cohort was representative of the spectrum of women suffering from vulvar pain. There was no correlation between the different pain measures. This was seen on scatter plots and confirmed with Spearman correlation coefficients less than eight. Conclusion There is no correlation between the commonly used pain measures in women presenting with vulvar pain. Better characterization and understanding of women suffering from vulvar pain is required.

description: Abstract 
The objectives of this study were twofold: (a) to assess the current business ethics climate through managerial ethics, job satisfaction, and organizational commitment from the perspectives of employees within the government–owned airports in Thailand, and (b) to provide the information to the airport management to get a better understanding and to identify an appropriate strategy in order to improve working ethics, job satisfaction, and organizational commitment of their employees.  Seven indicators of the managerial ethics variable were selected. These indicators consist of Good Citizenship, Integrity, Courage, Common Interest, Determination, Fairness, and Role Model. The five indicators of employees' job satisfaction were based on the common characteristics of job satisfaction identified, including Salary, Promotion, Co–workers, Supervisors, and the Job itself. The three indicators of employees' commitment were based on the common theme, which consists of Affective Commitment, Continuance Commitment, and Normative Commitment. Perceptions of the 15 indicators were collected by utilizing a questionnaire with a five–point Likert–type scale.  The sample was 318 employees within the selected 26 government–owned airports of the Department of Airport of Thailand. Descriptive and correlational statistics were used to analyze the collected data. The relationship between socio–demographic profile, managerial ethics, job satisfaction, and organizational commitment was determined. The results suggested valuable insight into the managerial ethics, job satisfaction, and organizational commitment of the organization.  Overall, the employees shared a generally high positive opinion of their managerial ethics and had a positive perception of their job satisfaction. For organizational commitment, overall, the employees showed their commitment as neutral. There was a different level of relationship between each of the indicators of managerial ethics, job satisfaction, and organizational commitment. All significant correlation identified was positive, in which the higher level of managerial ethics of the head/supervisors/managers, the employees most likely to have better job satisfaction and organizational commitment in the government–owned airports.

description: Objectives. This study examined the efficacy of a relationship-based HIV/sexually transmitted disease prevention program for heterosexual couples and whether it is more effective when delivered to the couple or to the woman alone. Methods. Couples (n = 217) were recruited and randomized to (1) 6 sessions provided to couples together (n = 81), (2) the same intervention provided to the woman alone (n = 73), or (3) a 1-session control condition provided to the woman alone (n = 63). Results. The intervention was effective in reducing the proportion of unprotected and increasing the proportion of protected sexual acts. No significant differences in effects were observed between couples receiving the intervention together and those in which the woman received it alone. Conclusions. This study demonstrates the efficacy of a relationship-based prevention program for couples at risk for HIV infection.

description: We investigate the properties of the XY pyrochlore antiferromagnet with local <111> planar anisotropy. We find the ground states and show that the configurational ground state entropy is subextensive. By computing the free energy due to harmonic fluctuations and by carrying out Monte Carlo simulations, we confirm earlier work indicating that the model exhibits thermal order-by-disorder leading to low temperature long-range order consisting of discrete magnetic domains. We compute the spin wave spectrum and show that thermal and quantum fluctuations select the same magnetic structure. Using Monte Carlo simulations, we find that the state selected by thermal fluctuations in this XY pyrochlore antiferromagnet can survive the addition of sufficiently weak nearest-neighbor pseudo-dipolar interactions to the spin Hamiltonian. We discuss our results in relation to the Er2Ti2O7 pyrochlore antiferromagnet.

description: Bibliography: p. 116-117

description: The purpose of this research is to develop recommendations for operating wells with unstable production rates. The geological section of Samotlor field is represented by a thick (up to 3,000 m) series of sedimentary rocks located on the eroded surface of folded foundation. As of January 1, 2010, there were 1,576 wells of which 65% are equipped with ESPs and 24% are equipped with sucker rod pumps. The wells equipped with ESPs ensure 74% of production. An analysis of the existing methods for selecting ESPs was carried out in accordance with the established objectives. The analysis demonstrated that pump is selected on the basis of several assumptions without taking into consideration possible changes in well operation which may occur with time. Thus one can assume that when the well parameters change in the process of operation, the selection of equipment may no longer be appropriate. An analysis of technological modes of operation of oil wells demonstrated that there are groups of wells that are characterized by technologically stable and unstable modes as well as the groups with an unvaried decrease of production rates and successful and unsuccessful optimization. This analysis was based on the data from 900 wells. The analysis of pump modes of operation indicated that pumps are often operated in non-optimal mode outside of their working ranges, main types and sizes. Thus, despite numerous existing methods and software for selecting submersible equipment for wells, it is not always possible to optimize the well operation which results in a fairly large number of wells with unstable production rates. The unstable production rates during well operation lead to reduction of ESP's efficiency and an increase of their vibration. It also adversely affects the formation by drawdown pressure drops. There are various control methods and technkaJ devices that aJlow ensuring various modes of operation of hydraulic systems. As a result of performed analysis the most effective devices for stabilization of well operation are identified: automatic transmission and indirect bypass valve. To reduce the adverse impact on ESP and formation it 1s recommended to use the thyristor turbulent flow wave frequency converter. ESP benchmark tests were carried out in the Central Production Maintenance Base in Langepas to study the vibration level in various modes. The tests demonstrated that the vibration level exceeds allowable level by approximately 25% with pump operating at the limits of its working ranges. Such vibration may be reduced by thyristror wave frequency converter. A bench test in the field and in the laboratory of the chair of Machinery and Equipment for Oil and Gas Industry demonstrated high effectiveness of this device.

Single channel properties of the slow cardiac potassium current, IKs
Creators: name: Werry, Daniel
Publisher: name: University of British Columbia
Year: 2011

description: The slow potassium current, IKs, abbreviates the cardiac action potential by repolarizing the membrane to a resting state. Mutations in the pore-forming IKs subunit, KCNQ1, cause long QT syndrome type 1 (LQT1), which increases risk of fatal arrhythmia. Despite the physiological and clinical importance of IKs, little is known about the elementary events that underlie the unique biophysical properties of the channel, and how these elementary events are altered in the face of disease. This thesis investigates single channel recordings of IKs with and without mutations that cause LQT1 using patch clamp electrophysiology. Single channel IKs is described by slow and fast gating processes. The channel is slow to open, but flickers rapidly between open and closed states in non-deactivating bursts. Long latency periods to opening underlie the slow activation of IKs at depolarized potentials. Channel activity is cyclic with periods of high activity followed by quiescence, leading to an overall low open probability. The mean single channel conductance was determined to be 3.2 pS and long-lived subconductance levels coupled to activation were observed. Single channel properties of IKs with LQT1 mutations in the S3 helix of the voltage sensing domain in KCNQ1 were investigated to uncover pathogenic mechanisms at the single molecule level. Open probability was reduced in loss-of-function mutations (D202H, I204F and V205M) and increased in a unique gain-of-function mutation (S209F) that may cause LQTS from a reduced number of functional channels at the cell surface. The mean duration of open events correlated well with deactivation rate in all mutants and first latency to opening determined activation rate. From these results, we attributed the pathogenic mechanisms of LQT1 mutations to alterations in the stability of specific channel states.

description: This article presents a damage detection method for prestressed reinforced concrete (PRC) elements based on free vibration tests and nonlinear damping identification. Integrated static and dynamic experiments were carried out on three precast PRC beam specimens. The static loading induced different levels of damage to the beams. At each damage level, impulsive loading was applied to the beams and the free vibration response was measured. The dynamic response data were processed using different methods including the multi-input multi-output (MIMO) curve fitting and the Hilbert transform techniques. A strong correlation is observed between the level of concrete damage (cracks) and the amount of nonlinear energy dissipation that can be modeled by means of quadratic damping. The nonlinear damping can be extracted from the free vibration response for each vibration mode. The proposed method is suited for quality control when manufacturing precast PRC members, and can be further extended for in situ detection of damage in concrete structures under ambient vibration.

description: We have performed x-ray absorption spectroscopy (XAS) measurements on a series of Ir-based 5d transition metal compounds, including Ir, IrCl3, IrO2, Na2IrO3, Sr2IrO4, and Y2Ir2O7. By comparing the intensity of the "white-line" features observed at the Ir L2 and L3 absorption edges, it is possible to extract valuable information about the strength of the spin-orbit coupling in these systems. We observe remarkably large, non-statistical branching ratios in all Ir compounds studied, with little or no dependence on chemical composition, crystal structure, or electronic state. This result confirms the presence of strong spin-orbit coupling effects in novel iridates such as Sr2IrO4, Na2IrO3, and Y2Ir2O7, and suggests that even simple Ir-based compounds such as IrO2 and IrCl3 may warrant further study. In contrast, XAS measurements on Re-based 5d compounds, such as Re, ReO2, ReO3, and Ba2FeReO6, reveal statistical branching ratios and negligible spin-orbit coupling effects.

description: Some pages are in colour.
description: Wettability is a profoundly important parameter need to be understood in reservoir engineering. It has direct impact on the nature of fluid trapping, residual oil saturations, and mechanisms of displacement at the pore scale. Unfortunately, this parameter is very difficult to measure in unconsolidated systems, such as the oil sands of northern Alberta. Furthermore, in oil sands where the oil viscosity is much higher than that of water, conventional Amott/USBM testing cannot be applied. Therefore alternative technologies should be considered. Previous researches have shown that NMR technology could be used for wettability characterization. This study systematically investigated the NMR signal variation trend on well characterized model samples under different wettability conditions, as well as the effect of viscosity of oil phase on NMR signal variation. A better understanding on the effects of wetting conditions and saturation on NMR T 2 relaxation variation were obtained for both water and oil phase. Based on these findings, the wettability condition derivations from fluid NMR signal distribution analysis were explained. Furthermore, the effect of connate water on oil sands wettability as well as the bitumen recovery from oil sands was also investigated.

description: We report a broad-band continuum light source with high power, low noise and a smooth spectrum centered at 1.15 μm for ultrahigh-resolution optical coherence tomography (OCT). The continuum is generated by self-phase modulation using a compact 1.059 μm femtosecond laser pumping a novel photonic crystal fiber, which has a convex dispersion profile with no zero dispersion wavelengths. The emission spectrum is red-shifted from the pump wavelength, ranges from 800 to 1300 nm and results in a measured axial resolution of ~2.8 μm in air. We demonstrate ultrahigh-resolution OCT imaging of biological tissue using this light source. The results suggest PCF with this type of dispersion profile is advantageous for generating SC as a light source for ultrahigh-resolution OCT.

description: This project focused on teacher preparation for health and well-being in schools through professional development for teachers in a rural K-12 school in Alberta. Although the role of schools in prevention efforts has been explored in the literature, few studies have examined sensitizing teachers to health promoting messages, including their own conception of and attitudes toward weight. The study was conducted with twelve teachers and fifty-seven students. Body image satisfaction, school climate, self-efficacy, and weight-bias were assessed before and after a professional in-service. At three month follow-up the above were reassessed, and qualitative data regarding teaching practice was collected. Results suggest that teachers are not immune to cultural messages that perpetuate the thin ideal and weight-bias. Providing professional development for teachers may promote more positive attitudes and practice regarding body image, weight-bias, and weight/eating-related concerns. Future evaluation with a larger sample size (more than one school community) is needed.

description: This paper examines the relationship between HIV risk and criminal justice involvement among a random sample of 356 men enrolled in methadone maintenance treatment programs in New York City. Bivariate and logistic regression analyses were performed to estimate the associations between measures of criminal justice involvement and participant HIV risk, controlling for socio-demographic variables. A lifetime history of incarceration was significantly associated with being HIV positive (Adjusted OR = 5.08). Recent arrest was associated with unprotected vaginal sex and having multiple female sexual partners. Sex trading was associated with both arrest and incarceration, and the strongest association was found between selling sex and recent incarceration (Adjusted OR = 5.69). Results suggest that recent criminal justice involvement among men with substance abuse histories is associated with increased HIV risk behaviors. Findings underscore the need for targeted HIV prevention efforts for men on methadone with a recent history of arrest or incarceration.

description: We calculate the amplitude T_1 for forward doubly-virtual Compton scattering in heavy-baryon chiral perturbation theory, to fourth order in the chiral expansion and with the leading contribution of the gammaNDelta form factor. This provides a model-independent expression for the amplitude in the low-momentum region, which is the dominant one for its contribution to the Lamb shift. It allows us to significantly reduce the theoretical uncertainty in the proton polarisability contributions to the Lamb shift in muonic hydrogen. We also stress the importance of consistency between the definitions of the Born and structure parts of the amplitude. Our result leaves no room for any effect large enough to explain the discrepancy between proton charge radii as determined from muonic and normal hydrogen.

description: This study examines the longitudinal relationship between personal and sexual partner incarceration and subsequent HIV risk behaviors among drug-involved men and their primary female sexual partners. A random sample of 356 men in methadone treatment in New York City were interviewed at baseline, 6 and 12 months; these men also reported information on their primary female sexual partners. Female partner recent incarceration was associated with subsequent increase in multiple partnerships for the male participants (AOR: 3.31; 95% C.I.: 1.26-8.72, P < .05). Female partner incarceration was also associated with reduced likelihood of subsequent unprotected sex between primary partners (AOR: .13; 95% C.I.: .05-.40, P < .01); this finding is somewhat unique and warrants further investigation. Findings support the notion of mutual influence in the case of female partner incarceration, which is associated with both female partner and male partner risk behaviors. HIV prevention implications are discussed, including the need for couple-based HIV prevention interventions targeting couples affected by incarceration.

description: Presented during Welcome Remarks & Plenary Session I.
description: Conservation and stewardship of our natural resources have been fundamental to the missions of a number of our public agencies in the United States since their inception. However, as important as public lands have been for conservation in the United States, most of the nation's land is in private ownership. The amount, distribution, and characteristics of private lands, combined with the spatial scales at which ecological systems operate, create a special and critical conservation role for private lands. While many of the strategies for conservation on public lands are also effective on private lands, private lands present special opportunities for conservation, as well as special challenges. As is true in many regions, conservation on private lands has played a critical role in sustaining wildlife, biodiversity, and ecosystems in Northern Colorado. Examples of innovative conservation partnerships and efforts focused on conservation of private lands in the region are presented. Lessons learned from these case studies and the shifting dynamics facing our natural systems suggest a number of lessons and future directions in conservation, education, and research.

description: Contemporary society recognizes that corporate actors have the ability to serve as both constructive and destructive actors in 'fragile' or conflict laden states. In response, Western public opinion has signalled its expectation that business should maximize its positive impact and contribute to social good in these states. The current corporate social responsibility (CSR) trend aimed at satisfying this expectation is predominantly defined by a loose framework guided by 'sustainability'. Alternatively, little attention has been directed towards the plausible role corporate actors can play in cultivating peace and security abroad. In response to this gap in research Deitelhoff and Wolf (2010) have presented a behavioural model establishing benchmarks for what they call 'corporate security responsibility' (CSecR), or corporate policies and activities aimed at cultivating peace and physical security in fragile states. Few case studies have been explored using this model and as a result its potential value remains ambiguous. Consequently, a gap exists in the CSR literature. This thesis aims to explore this gap by examining the experiences and CSR initiatives pursued by two Canadian extractive firms with operations in fragile states: Talisman Energy in Sudan and Anvil Mining in Congo. By doing so the research will determine whether or not the CSR policies and activities implemented in each case aligned with CSecR behaviour and subsequently explore the potential utility of pursuing Deitelhoff and Wolfs (2010) model as an alternative.

description: Identifying which correlations among distant observers are possible within our current description of Nature, based on quantum mechanics, is a fundamental problem in Physics. Recently, information concepts have been proposed as the key ingredient to characterize the set of quantum correlations. Novel information principles, such as, information causality or non-trivial communication complexity, have been introduced in this context and successfully applied to some concrete scenarios. We show in this work a fundamental limitation of this approach: no principle based on bipartite information concepts is able to single out the set of quantum correlations for an arbitrary number of parties. Our results reflect the intricate structure of quantum correlations and imply that new and intrinsically multipartite information concepts are needed for their full understanding.

A Social Network Profile and HIV Risk Among Men on Methadone: Do Social Networks Matter?

description: The paper describes structural and HIV-related network characteristics and examines associations between these various social network domains and HIV risk behaviors among a sample of 356 men randomly selected from a methadone maintenance treatment program (MMTP) in New York City. Multiple logistic regression analyses suggest that (1) a higher level of perceived sexual risk among network members, referred to as "alters" in this study, was associated with an increased likelihood of the participant engaging in sexual risk behaviors; (2) participants who indicated that they exchanged encouragement with a higher number of network alters about using condoms were less likely to report engaging in unprotected sex; and (3) participants who indicated that they talked about HIV risks with a higher number of network alters were less likely to engage in unprotected sex in the past 6 months. Collectively, these findings support the notion that networks may influence the adoption of risk reduction strategies in this population. Implications of the findings for HIV prevention network interventions for men in MMTPs are discussed.
Agent of influence and change: the primacy of culture in smart power strategies

description: Bibliography: p. 83-87
description: Contemporary events have shown that military or hard power, while necessary in some instances, is not always the best solution to the evolving threats faced by states today. A combination of hard and soft ("attractive") power - smart power, is necessary. However, the nature of smart power itself is elusive and has not been thoroughly studied. Our current understanding of smart power is woefully inadequate; there is no consensus of how a balance may be struck between soft and hard power, how they relate to one another, nor how they can be mindfully developed. The purpose of this thesis is to help bridge this gap in understanding. Consequently, the results of my research suggest that culture plays a pre-eminent role in the development of smart power, and if we are to harness the latter, then we must develop a more thorough understanding of how culture is inextricably linked to it.

description: This paper supports two years of artistic research and is intended to act as an appending document to my thesis exhibition Braided Hair. It addresses three main themes surrounding braided hair as both material for and subject of my work: Cultural 'In-Betweeness', Process, and Beauty of 'Uncanniness'. I draw from personal and cultural narratives, familiar processes and materials to create unfamiliar and surrealistic objects and spaces, celebrating the braided hair as a cultural signifier. It is intended that the objects and installations evoke a visceral experience, echoing the diverse and hybrid cultural spaces around me. I am fascinated with concepts of co-existence, accord, discord, connection and disconnection especially as they relate to cultural dislocation, perceptions of identity and beauty.

description: The application of high end computing to astrophysical problems, mainly in the galactic environment, is under development since many years at the Dep. of Physics of Sapienza Univ. of Roma. The main scientific topic is the physics of self gravitating systems, whose specific subtopics are: i) celestial mechanics and interplanetary probe transfers in the solar system; ii) dynamics of globular clusters and of globular cluster systems in their parent galaxies; iii) nuclear clusters formation and evolution; iv) massive black hole formation and evolution; v) young star cluster early evolution. In this poster we describe the software and hardware computational resources available in our group and how we are developing both software and hardware to reach the scientific aims above itemized.

description: Without demanding a specific form for the inflaton potential, we obtain an estimate of the contribution to the curvature perturbation generated during the linear era of the hybrid inflation waterfall. The spectrum of this contribution peaks at some wavenumber $k=k_*$, and goes like $k^3$ for $k\ll k_*$, making it typically negligible on cosmological scales. The scale $k_*$ can be outside the horizon at the end of inflation, in which case $ζ=- (g^2 - \vev{g^2})$ with $g$ gaussian. Taking this into account, the cosmological bound on the abundance of black holes is likely to be satisfied if the curvaton mass $m$ much bigger than the Hubble parameter $H$, but is likely to be violated if $m\lsim H$. Coming to the contribution to $ζ$ from the rest of the waterfall, we are led to consider the use of the `end-of-inflation' formula, giving the contribution to $ζ$ generated during a sufficiently sharp transition from nearly-exponential inflation to non-inflation, and we state for the first time the criterion for the transition to be sufficiently sharp. Our formulas are applied to supersymmetric GUT inflation and to supernatural/running-mass inflation
