International practicums and nursing students' understanding of culture : an interpretive description
Creators: name: Laidlaw, Nicola Ann
Publisher: name: University of British Columbia
Year: 2014

description: Canadian nurses and nursing students are required daily to interact with and care for individuals of diverse cultural backgrounds in a manner that assures high quality, respectful care. While international practicums are being employed by some nursing schools to prepare nursing students for this challenge, there is a scarcity of literature examining the success of such programs. This qualitative study explores nursing students' accounts of culture before, during, and after an international practicum, to explore how the notion of 'culture' is developed in nursing students taking part in an international practicum. This study was designed using a critical cultural framework, the premise of which is that we see individuals not as simply belonging to a particular cultural group, a cultural “other”, but that they be recognized as residing within a unique historical, social, economic and political context that is unlikely to be identical to that of any other member of their cultural group. The research was conducted using interpretive description as the research methodology. Purposive criterion sampling was employed to select participants. This research emphasized the complexity of the notion of culture. It has been suggested that these practicums can be problematic in terms of the cultural understanding they instill in students, perhaps even reinforcing the essentialist notions of culture that we are attempting to replace. The importance of self-reflection to reveal personal biases, values and assumptions, as well as the recognition of the sociopolitical influences on the lives of individuals emerged as key factors in facilitating a critical cultural understanding of culture. This research highlighted the need that nurse educators be supported in their own journey toward an understanding of the concepts of `culture` and `cultural safety`. The findings of this research support the idea that nursing students, for the most part, retain their essentialist views of culture, even during and after participation in an international practicum. It emphasizes the need to rethink how nursing students are prepared pre-departure to approach their practicum with a critical cultural eye, and the importance of daily reflection and guided discussions during the practicum.

Confused categories, situational races, authenticity and the implementation of affirmative action : how young Brazilians manage the boundaries of racial identification
Creators: name: De Oliveira, Beatriz Arcoverde
Publisher: name: University of British Columbia
Year: 2014

description: Brazil’s vision of race has been changing. In contrast with its former tendency to avoid static racial identifications and discussions of race, the country is pushing toward clearer racial definitions in order to institute racially targeted programs, such as racial quotas for Non-Whites in public universities. Using in-depth interviews from 19 students who entered university through racial quotas, this paper explores how these students envision fixed categories for themselves, how they deal with these categories in different situations, and what they think the implications of these shifts in racial understanding will be. The study shows that the racial categories proposed in legislation often do not represent the way students see themselves; indeed, they may not feel that racial categorization is something natural to their existence before applying for university. Respondents often feel discomfort dealing with the idea of categorization, as well as with the meaning of each category, and as a result they sometimes appropriate and redefine the categories. They speak of being reminded of their racialized bodies when contrasted or compared with others or their environment, and they demonstrate that race is a very flexible concept in their minds, varying in different situations. As well, their perceptions of race implicate ideas about social class and even personal aesthetics that are easily mutable. In trying to come to terms with the idea of race and how to bound it to something they can understand and grasp, students come to dispute the authenticity of racial claims. These disputes over how someone’s race is authentic may provide a space in which new meanings of race and racial categories can be created.

Slow quench dynamics of the Kitaev model: anisotropic critical point and effect of disorder

description: We study the non-equilibrium slow dynamics for the Kitaev model both in the presence and the absence of disorder. For the case without disorder, we demonstrate, via an exact solution, that the model provides an example of a system with an anisotropic critical point and exhibits unusual scaling of defect density $n$ and residual energy $Q$ for a slow linear quench. We provide a general expression for the scaling of $n$ ($Q$) generated during a slow power-law dynamics, characterized by a rate $τ^{-1}$ and exponent $α$, from a gapped phase to an anisotropic quantum critical point in $d$ dimensions, for which the energy gap $Δ_{\vec k} \sim k_i^z$ for $m$ momentum components ($i=1..m$) and $\sim k_i^{z'}$ for the rest $d-m$ components ($i=m+1..d$) with $z\le z'$: $n \sim τ^{-[m + (d-m)z/z']να/(zνα+1)}$ ($Q \sim τ^{-[(m+z)+ (d-m)z/z']να/(zνα+1)}$). These general expressions reproduce both the corresponding results for the Kitaev model as a special case for $d=z'=2$ and $m=z=ν=1$ and the well-known scaling laws of $n$ and $Q$ for isotropic critical points for $z=z'$. We also present an exact computation of all non-zero, independent, multispin correlation functions of the Kitaev model for such a quench and discuss their spatial dependence. For the disordered Kitaev model, where the disorder is introduced via random choice of the link variables $D_n$ in the model's Fermionic representation, we find that $n \sim τ^{-1/2}$ and $Q\sim τ^{-1}$ ($Q\sim τ^{-1/2}$) for a slow linear quench ending in the gapless (gapped) phase. We provide a qualitative explanation of such scaling.

description: Climate change gives rise to numerous environmental stresses, including soil salinity. Salinity/salt stress is the second biggest abiotic factor affecting agricultural productivity worldwide by damaging numerous physiological, biochemical, and molecular processes. In particular, salinity affects plant growth, development, and productivity. Salinity responses include modulation of ion homeostasis, antioxidant defense system induction, and biosynthesis of numerous phytohormones and osmoprotectants to protect plants from osmotic stress by decreasing ion toxicity and augmented reactive oxygen species scavenging. As most crop plants are sensitive to salinity, improving salt tolerance is crucial in sustaining global agricultural productivity. In response to salinity, plants trigger stress-related genes, proteins, and the accumulation of metabolites to cope with the adverse consequence of salinity. Therefore, this review presents an overview of salinity stress in crop plants. We highlight advances in modern biotechnological tools, such as omics (genomics, transcriptomics, proteomics, and metabolomics) approaches and different genome editing tools (ZFN, TALEN, and CRISPR/Cas system) for improving salinity tolerance in plants and accomplish the goal of “zero hunger,” a worldwide sustainable development goal proposed by the FAO.

description: Starting from the first law of thermodynamics, $dE=T_hdS_h+WdV$, at apparent horizon of a FRW universe, and assuming that the associated entropy with apparent horizon has a quantum corrected relation, $S=\frac{A}{4G}-α\ln \frac{A}{4G}+β\frac{4G}{A}$, we derive modified Friedmann equations describing the dynamics of the universe with any spatial curvature. We also examine the time evolution of the total entropy including the quantum corrected entropy associated with the apparent horizon together with the matter field entropy inside the apparent horizon. Our study shows that, with the local equilibrium assumption, the generalized second law of thermodynamics is fulfilled in a region enclosed by the apparent horizon.

description: We present a new decoding procedure to transmit classical information in a quantum channel which, saturating asymptotically the Holevo bound, achieves the optimal rate of the communication line. Differently from previous proposals, it is based on performing a sequence of (projective) YES/NO measurements which in N steps determines which codeword was sent by the sender (N being the number of the codewords). Our analysis shows that as long as N is below the limit imposed by the Holevo bound the error probability can be sent to zero asymptotically in the length of the codewords.

description: Lately, different methods for broadcasting future digital TV in a single frequency network (SFN) have been under an intensive study. To improve the transmission to also cover suburban and rural areas, a hybrid scheme may be used. In hybrid transmission, the signal is transmitted both from a satellite and from a terrestrial site. In 2008, Y. Nasser et al. proposed to use a double layer 3D space-time (ST) code in the hybrid 4 x 2 MIMO transmission of digital TV. In this paper, alternative codes with simpler structure are proposed for the 4 x 2 hybrid system, and new codes are constructed for the 3 x 2 system. The performance of the proposed codes is analyzed through computer simulations, showing a significant improvement over simple repetition schemes. The proposed codes prove in addition to be very robust in the presence of power imbalance between the two sites.

Le présent projet a été mené auprès d’élèves belges de 14-15 ans. Ceux-ci ont bénéficié d’une forme de liberté pédagogique et ont créé leurs propres cours d’anglais pour des enfants de 8-9 ans. Durant cette recherche-intervention, l’enseignante-chercheure a pris une posture d’accompagnatrice. L’objectif était d’identifier les effets-tuteurs génériques (à partir des écrits ou de la documentation) et spécifiques (propres au contexte). Une méthodologie mixte incluant une comparaison des résultats des tuteurs avec leurs pairs des années antérieures n’ayant pas bénéficié du projet ainsi qu’un recueil d’avis écrits et des entretiens semi-directifs, a été menée. Des effets-tuteurs génériques comme la coopération et la réflexion sur l’activité enseignante ainsi que des effets-tuteurs spécifiques comme la créativité dans la préparation des cours ainsi que la conscience de l’importance de l’ergonomie de la salle de classe, ont été identifiés.

description: Vinca Alkaloids are microtubule targeting agents commonly used in several chemotherapy regimens to disrupt mitosis of cancerous cells1. These drugs work effectively well in several anti-cancer drug therapies due to their unique mechanism of action that often works to supplement killing of cancer cells1. The most widely used Vinca alkaloid is vincristine, and the majority of case reports involving administration errors result from inappropriate administration of vincristine1.

description: We present a quasi-static finite element simulator for human face animation. We model the face as an actuated soft body, which can be efficiently simulated using Projective Dynamics (PD). We adopt Incremental Potential Contact (IPC) to handle self-intersection. However, directly integrating IPC into the simulation would impede the high efficiency of the PD solver, since the stiffness matrix in the global step is no longer constant and cannot be pre-factorized. We notice that the actual number of vertices affected by the collision is only a small fraction of the whole model, and by utilizing this fact we effectively decrease the scale of the linear system to be solved. With the proposed optimization method for collision, we achieve high visual fidelity at a relatively low performance overhead.

Aubert (1960) described two of these (in genus Illiesia); N. spinosa (Aubert) has two pairs of slender, upwardly directed spines on the lateral margins of the upper paraproct lobes and the lower lobes appear relatively unarmed, and N. biloba (Aubert) also bears prominent spines on the upper paraproct lobes, but lack a pair of spines on the apex. Illies (1961) redescribed N. areolata Navas, and his redescription is consistent with our male specimen in having the lateral margins of the lower paraproct lobes sinuate along the entire length.

Survival of the misfits : dependency care as a site for political representation
Creators: name: Munawar, Sarah
Publisher: name: University of British Columbia
Year: 2014

description: From physicians advising families to pull the plug on the to-be-disabled, to the eugenics movement and sterilization laws, at the core of threats to the existence of dependents with severe disability are narratives of tragedy and misfittedness. Through this horizon, the embodiment of difference is ostracised as deviancy or deficiency and dependents living with severe disability are least recognizable as political subjects due to their structural positioning--casting relations of care to the margins of public accountability. What increases the risk of death, violence or injury is not the dependencies or corporeal embodiment of individuals with severe disability, but rather the lack of institutional support for relations of care--their primary means to sustenance. The multi-dimensional practice of care, as it arises from dependency and corporeal vulnerability, is a political resource through which dependents with severe disability can exercise a greater degree of authorship and self-definition in the democratic claims-making process. Central to this task is mapping the alignment between the values of attentiveness and responsiveness, at the heart of the ethics of care, and what democratic representation draws its legitimacy from: proximity and attention to the particularity of the represented. The shared perspective between dependents and dependency workers, looking out from a dependency relation, when mobilized in the process of representation, paves way for the empowerment of the dependent because it increases not only his self-esteem as an individual, but also, the performance of institutions of care--shielding dependents from the differential distribution of precarity. The process of representation, as exercised through the activity of care, must be as fluid as the move from wheelchair, to walker, to cane, to his one's own legs—whatever the shifts in capacities may be for the dependent, the dependency worker adjusts her care through attentiveness. This requires reconciling the politics of presence with the physical (the corporeal situation of the political subject): designing institutions in a way maintains an ever-present, ear to the ground, process of representation between the representative and the represented, which is also, fine-tuned to the particularity of the individual's structural positioning, the changing human body, perspectives etc.
Do Damped and Sub-damped Lyman-alpha Absorbers Arise in Galaxies of Different Masses?

description: We consider the questions of whether the damped Lyman-alpha (DLA) and sub-DLA absorbers in quasar spectra differ intrinsically in metallicity, and whether they could arise in galaxies of different masses. Using the recent measurements of the robust metallicity indicators Zn and S in DLAs and sub-DLAs, we confirm that sub-DLAs have higher mean metallicities than DLAs, especially at $z \lesssim 2$. We find that the intercept of the metallicity-redshift relation derived from Zn and S is higher than that derived from Fe by 0.5-0.6 dex. We also show that, while there is a correlation between the metallicity and the rest equivalent width of Mg II $λ2796$ or Fe II $λ2599$ for DLAs, no correlation is seen for sub-DLAs. Given this, and the similar Mg II or Fe II selection criteria employed in the discovery of both types of systems at lower redshifts, the difference between metallicities of DLAs and sub-DLAs appears to be real and not an artefact of selection. This conclusion is supported by our simulations of Mg II $λ2796$ and Fe II $λ2599$ lines for a wide range of physical conditions. On examining the velocity spreads of the absorbers, we find that sub-DLAs show somewhat higher mean and median velocity spreads ($Δv$), and an excess of systems with $Δv > 150$ km s$^{-1}$, than DLAs. Compared to DLAs, the [Mn/Fe] vs. [Zn/H] trend for sub-DLAs appears to be steeper and closer to the trend for Galactic bulge and thick disk stars, possibly suggesting different stellar populations. The absorber data appear to be consistent with galaxy down-sizing. The data are also consistent with the relative number densities of low-mass and high-mass galaxies. It is thus plausible that sub-DLAs arise in more massive galaxies on average than DLAs.

description: We formulate a model of a semiconductor Quantum Dot laser with injection of spin-polarized electrons. As compared to higher-dimensionality structures, the Quantum-Dot-based active region is known to improve laser properties, including the spin-related ones. The wetting layer, from which carriers are captured into the active region, acts as an intermediate level that strongly influences the lasing operation. The finite capture rate leads to an increase of lasing thresholds, and to saturation of emitted light at higher injection. In spite of these issues, the advantageous threshold reduction, resulting from spin injection, can be preserved. The "spin-filtering" effect, i.e., circularly polarized emission at even modest spin-polarization of injection, remains present as well. Our rate-equations description allows to obtain analytical results and provides transparent guidance for improvement of spin-lasers.

description: Las terapias avanzadas constituyen un dominio donde convergen tecnologías muy diversas. La presentación distorsionada de resultados de investigaciones a menudo muy preliminares contribuye a suscitar expectativas que fácilmente pueden ser instrumentalizadas para publicitar tratamientos costosos, de alto riesgo o fraudulentos. El desafío para la comunicación social de la ciencia consiste en incorporar resultados de la investigación sobre nuevos modelos de comprensión pública de la ciencia, útiles para suscitar predisposiciones favorables hacia este dominio complejo de tecnologías, sin renunciar a los elementos de control que posibilitan una comprensión crítica de la ciencia.

Instrumental liberalization : China's new practice in bilateral investment treaties in the 2000's
Creators: name: Kuang, Yingqiu
Publisher: name: University of British Columbia

description: The spread of Bilateral Investment Treaties in the past decades, as a popular way to promote and protect foreign direct investment between countries, is no doubt a vivid example that displays the triumph of globalization and the diffusion of liberalization. By the end of 2013, most countries of the world have participated and signed 2,857 such treaties (UNCTAD, 2013). China, among them, is definitely a latecomer and a distinct player. Until 1982, which is 23 years later than Germany’s first treaty with Pakistan, China started its BIT program, and soon has become the world’s second largest contract party. As of its particularity, from the very beginning, China became one of the few developing economies (BRICS states in particular) that were able to sign treaties favoring their own economic interests and sovereignty; soon after, China is also the first and the only country among them that chose to abolish such privileges and started its new, liberalized practice. Stemming from China’s unique development trajectory, my research question asks: what has motivated Chinese government to make such unprecedented change? What was the rationale behind this behavior so distinct from other BRIC countries? The emerging causal narrative comes from Steve Vogel’s theory of “asymmetric regulation” in competitive markets, with the analysis of the specific domestic political and economic constraints within China. This paper argues that China’s new, liberalized practice in BITs is first a policy outcome to increase the international competitiveness of the national industry; more than that, it is also an instrumental liberalization effort made by the central government to strengthen the political control over the locals and to re-shape China’s understanding of the international order, especially the South-South cooperation.
The Dangers of Administering Fleet Enemas in Patients with Chronic Kidney Disease

description: Chronic Kidney Disease (CKD) is a disease in which abnormalities in the kidneys and/or reduced kidney function are present for more than 3 months with implications to cause negative health impact in chronic renal failure patients.1 One of the most common abnormalities associated with CKD are bone and mineral disorders associated with homeostasis of calcium and phosphorous.1 With further kidney decline, phosphorous elimination is reduced resulting in elevations in serum phosphorous levels.1 In addition, overall calcium levels are reduced resulting in low levels of serum calcium.1 Both hyperphosphatemia and hypocalcemia have been associated with adverse effects from administering fleet enemas in CKD patients. 2
Wind-driving protostellar accretion discs. II. Numerical method and illustrative solutions

description: (abridged) We continue our study of weakly ionized protostellar discs that are threaded by a large-scale magnetic field and power a centrifugally driven wind. It has been argued that in several protostellar systems such a wind transports a significant fraction of the angular momentum from at least some part of the disc. We model this case by considering a radially localized disc model in which the matter is well coupled to the field and the wind is the main repository of excess angular momentum. We consider stationary solutions in which magnetic diffusion counters the shearing and advection of the field lines. In Wardle & Königl we analysed the disc structure in the hydrostatic approximation and presented disc/wind solutions for the ambipolar diffusivity regime. In Königl, Salmeron & Wardle (Paper I) we generalized the hydrostatic analysis to the Hall and Ohm diffusivity domains and identified the parameter sub-regimes in which viable solutions occur. In this paper we test these results by deriving numerical solutions (integrated through the sonic critical surface) of the disc equations in the Hall domain. We confirm the predictions of the hydrostatic analysis and demonstrate its usefulness for clarifying the behaviour of the derived solutions. We show that the solutions can be extended to larger scales (so that they also cross the Alfvén critical surface) by matching the localized disc solutions to global wind solutions of the type introduced by Blandford & Payne. To facilitate this matching, we construct a library of wind solutions, which is made available to the community. The results presented in Wardle & Königl, Paper I and this work form a comprehensive framework for the study of wind-driving accretion discs in protostellar and other astrophysical environments. This tool could be useful for interpreting observations and for guiding numerical simulations of such systems.

Band Calculations for Ce Compounds with AuCu$_{3}$-type Crystal Structure on the basis of Dynamical Mean Field Theory I. CePd$_{3}$ and CeRh$_{3}$

description: Band calculations for Ce compounds with the AuCu$_{3}$-type crystal structure were carried out on the basis of dynamical mean field theory (DMFT). The auxiliary impurity problem was solved by a method named NCA$f^{2}$vc (noncrossing approximation including the $f^{2}$ state as a vertex correction). The calculations take into account the crystal-field splitting, the spin-orbit interaction, and the correct exchange process of the $f^{1} \rightarrow f^{0},f^{2}$ virtual excitation. These are necessary features in the quantitative band theory for Ce compounds and in the calculation of their excitation spectra. The results of applying the calculation to CePd$_{3}$ and CeRh$_{3}$ are presented as the first in a series of papers. The experimental results of the photoemission spectrum (PES), the inverse PES, the angle-resolved PES, and the magnetic excitation spectra were reasonably reproduced by the first-principles DMFT band calculation. At low temperatures, the Fermi surface (FS) structure of CePd$_{3}$ is similar to that of the band obtained by the local density approximation. It gradually changes into a form that is similar to the FS of LaPd$_{3}$ as the temperature increases, since the $4f$ band shifts to the high-energy side and the lifetime broadening becomes large.}

description: A wide range of multifield inflationary models generate non-Gaussian initial conditions in which the initial adiabatic fluctuation is of the form (zeta_G + g_{NL} zeta_G^3). We study halo clustering in these models using two different analytic methods: the peak-background split framework, and brute force calculation in a barrier crossing model, obtaining agreement between the two. We find a simple, theoretically motivated expression for halo bias which agrees with N-body simulations and can be used to constrain g_{NL} from observations. We discuss practical caveats to constraining g_{NL} using only observable properties of a tracer population, and argue that constraints obtained from populations whose observed bias is

description: Quantum approximate optimization algorithm (QAOA) is one of the popular quantum algorithms that are used to solve combinatorial optimization problems via approximations. QAOA is able to be evaluated on both physical and virtual quantum computers simulated by classical computers, with virtual ones being favored for their noise-free feature and availability. Nevertheless, performing QAOA on virtual quantum computers suffers from a slow simulation speed for solving combinatorial optimization problems which require large-scale quantum circuit simulation (QCS). In this paper, we propose techniques to accelerate QCS for QAOA using mathematical optimizations to compress quantum operations, incorporating efficient bitwise operations to further lower the computational complexity, and leveraging different levels of parallelisms from modern multi-core processors, with a study case to show the effectiveness on solving max-cut problems.
