description: Background: Hemifacial spasms are involuntary contractions of the muscles of one side of the face.

Case Report: Here, we report a 5-year-old female patient with a significant past medical history, including mucopolysaccharidosis type VI, who also presented with hemifacial spasms. Further investigations showed narrowing of skull foramina and hydrocephalus, but no compression of the facial nerve. Carbamazepine was given to the patient, which caused cessation of the spasms.

Discussion: Currently, there is no literature discussing the relationship between hemifacial spasms and mucopolysaccharidosis type VI; we have proposed that mucopolysaccharide deposits or dural thickening may contribute to nerve irritation.

description: The magnetic ground states of the isostructural double perovskites Ba$_2$NaOsO$_6$ and Ba$_2$LiOsO$_6$ are investigated with muon-spin rotation. In Ba$_2$NaOsO$_6$ long-range magnetic order is detected via the onset of a spontaneous muon-spin precession signal below $T_{\mathrm{c}}=7.2\pm 0.2\;\mathrm{K}$, while in Ba$_2$LiOsO$_6$ a static but spatially-disordered internal field is found below 8 K. A novel probabilistic argument is used to show from the observed precession frequencies that the magnetic ground state in Ba$_2$NaOsO$_6$ is most likely to be low-moment ($\approx 0.2$\,$μ_{\rm B}$) ferromagnetism and not canted antiferromagnetism. Ba$_2$LiOsO$_6$ is antiferromagnetic and we find a spin-flop transition at 5.5\,T. A reduced osmium moment is common to both compounds, probably arising from a combination of spin-orbit coupling and frustration.

description: In the Ω-model, a dual-curvature framework based on toroidal and poloidal dynamics leads naturally to a redefinition of physical constants and natural units. In this work we derive a geometric expression for the Rydberg constant. By replacing traditional SI definitions with Ω-units, the model defines a natural length unit, time unit, mass unit, and charge unit.

The bright and dark sides of personality, job performance, and imbalanced leadership in managers
Creators: name: Wiens, Thomas K.
Publisher: name: University of British Columbia
Year: 2019

description: There is considerable interest in finding ways to screen for dark personality traits (maladaptive interpersonal and personality tendencies) in personnel selection assessments given their pernicious effects on job performance and leadership behavior. This has proved challenging because of socially desirable response biases and ethical restrictions regulating the use of psychiatric measures. Recent advances in the understanding of the dimensional nature of personality suggest that measures of bright personality can be used to predict dark personality traits. The current research extends this research to the California Psychological Inventory (CPI) and employs multiple regression analyses to examine the bright–dark trait relationships in two samples of managers who underwent employment testing. Study 1 found that CPI scales significantly predicted each of the self-reported Hogan Development Survey (HDS) dark traits. Study 2 extended this research to supervisor ratings and found that CPI scales significantly predicted 6 out of 11 dark traits as rated by supervisors. Supervisor-rated dark traits were also negatively related to supervisor ratings of task performance and contextual performance, as well as positively related to counterproductive workplace behavior and job stress. Evidence also suggested that job stress and self-awareness may moderate the relationship between dark traits and counterproductive workplace behavior. Most of the dark traits were characterized by leadership behavior imbalances related to overdoing and/or underdoing forceful, enabling, or strategic behaviors. Conceptually, this study furthers our understanding of the relationship between dark personality traits and bright personality traits as measured by the CPI. Practically, it provides support for another method to screen for dark personality traits in workplace contexts. It also addresses the lack of observer assessments of dark personality in workplace contexts as well as the lack of research on counterproductive workplace behavior.

description: We report a study of the complex AC impedance of CVD grown graphene. We measure the explicit frequency dependence of the complex impedance and conductance over the microwave and terahertz range of frequencies using our recently developed broadband microwave Corbino and time domain terahertz spectrometers (TDTS). We demonstrate how one may resolve a number of technical difficulties in measuring the intrinsic impedance of the graphene layer that this frequency range presents, such as distinguishing contributions to the impedance from the substrate. From our microwave measurements, the AC impedance has little dependance on temperature and frequency down to liquid helium temperatures. The small contribution to the imaginary impedance comes from either a remaining residual contribution from the substrate or a small deviation of the conductance from the Drude form.

description: This is the second edition of my master dissertion. The VDM Verlag Dr.Müller Publishing Company from Germany had my thesis published in 2005.The book aimed to identify deterioration problems, repair and conservation needs of andesites on the walls of the Ankara Castle. Decay forms of walls were documented by visual examination. Samples taken from the surface of the weathered andesites were examined for their basic physical, mechanical compositional and minerological properties. The bulk density and total porosity were determined as basic physical properties. The mechanical properties were expressed as ultrasonic velocity and modulus of elasticity (Emod). Compositional and mineralogical properties were determined by optical microscopy and XRD analyses.Soluble salt content of the andesite samples was determined by spot tests of anions and electrical conductivity measurements. Findings were evaluated in terms of the long-term weathering behaviour of andesites under the effect of the prevailing climate, air pollution problems of Ankara, dampness problems of the structure, previous repairs with incompatible cement mortars.The surfaces of Ankara Castle andesite blocks were heavily weathered. The results were compared with the physical and mechanical properties of fresh andesites from Gölbaşı-Ankara quarry. The surface of the andesite blocks at the Ankara Castle, had low bulk density and high porosity, low ultrasonic velocity and low Emod values. Thin section and XRD analyses supported those results by revealing the presence of physical and chemical weathering on feldspars and other main minerals of andesite, as well as the presence of amorphous minerals at the surface.

Clinical medicine--Study and teaching

description: Background
Learning self-efficacy, defined as learners’ confidence in their capability to learn specific subjects, is crucial for the enhancement of academic progress, because it is positively correlated with academic achievements and effective learning strategy use. In this study, we developed a universal scale called the Learning Self-Efficacy Scale (L-SES) for Clinical Skills for undergraduate medical students and validated it through item analysis and content validity index (CVI) calculation.

Design
The L-SES was developed based on the framework of Bloom’s taxonomy, and the questions were generated through expert consensus and CVI calculation. A pilot version of the L-SES was administered to 235 medical students attending a basic clinical skills course. The collected data were then examined through item analysis.

Results
The first draft of the L-SES comprised 15 questions. After expert consensus and CVI calculation, 3 questions were eliminated; hence, the pilot version comprised 12 questions. The CVI values of the 12 questions were between .88 and 1, indicating high content validity. Moreover, the item analysis indicated that the quality of L-SES reached the qualified threshold. The results showed that the L-SES scores were unaffected by gender (t = −0.049; 95% confidence interval [−.115, .109], p > .05).

Conclusion
The L-SES is a short, well-developed scale that can serve as a generic assessment tool for measuring medical students’ learning self-efficacy for clinical skills. Moreover, the L-SES is unaffected by gender differences. However, additional analyses in relevant educational settings are needed.

description: Given a generic map between flagged vector bundles on a Cohen-Macaulay variety, we construct maximal Cohen-Macaulay modules with linear resolutions supported on the Schubert-type degeneracy loci. The linear resolution is provided by the Schubert complex, which is the main tool introduced and studied in this paper. These complexes extend the Schubert functors of Kraśkiewicz and Pragacz, and were motivated by the fact that Schur complexes resolve maximal Cohen-Macaulay modules supported on determinantal varieties. The resulting formula in K-theory provides a "linear approximation" of the structure sheaf of the degeneracy locus, which can be used to recover a formula due to Fulton.

The effect of exercise-induced fatigue and eccentric muscle damage on kinaesthesia
Creators: name: Grose, George Sebastian
Publisher: name: University of British Columbia
Year: 2017

description: The senses of position and movement are known collectively as kinaesthesia. Muscle spindles are length sensitive receptors, considered pivotal to these senses. Mechanical muscle vibration artificially stimulates muscle spindles and this can lead to illusory limb postures and movements, thereby disrupting kinaesthesia. Exercise induced fatigue also impairs kinaesthesia and this impairment persists if the exercise involves lengthening contractions that create eccentric muscle damage. It is not entirely clear why these lasting impairments occur. Using a targeted movement sequence with the unseen arm (a task that relies heavily on muscle spindles), this study utilized a novel paradigm to investigate task performance both before and after an eccentric based exercise protocol. By investigating the influence of vibration applied to the involved musculature, the results provide insight into how exercise acutely disrupts kinaesthesia. It was found that mechanical muscle vibration created a robust effect on task accuracy at all points during the study, causing participants to undershoot the targets (as previously described in the literature). The effects of exercise also caused a consistent error in task performance, but did not appear to influence the effect of vibration. This suggests that the nervous system continues to rely heavily on muscle spindles, even when they reside in a muscle exposed to damaging eccentric contractions.

description: A ghost dark energy model has been recently put forward to explain the current accelerated expansion of the Universe. In this model, the energy density of ghost dark energy, which comes from the Veneziano ghost of QCD, is proportional to the Hubble parameter, $ρ_D=αH$. Here $α$ is a constant of order $Λ^3_{QCD}$ where $Λ_{QCD}\sim 100 MeV$ is the QCD mass scale. We consider a connection between ghost dark energy with/without interaction between the components of the dark sector and the kinetic k-essence field. It is shown that the cosmological evolution of the ghost dark energy dominated Universe can be completely described a kinetic k-essence scalar field. We reconstruct the kinetic k-essence function $F(X)$ in a flat Friedmann-Robertson-Walker Universe according to the evolution of ghost dark energy density.

description: Background: Adult-onset Niemann–Pick Type C is a rare neurogenetic lysosomal disorder, whose diagnosis is often delayed and missed because of its heterogeneous clinical presentations and rarity as well as the lack of awareness of characteristic eye findings among neurologists.

Phenomenology Shown: Impaired smooth pursuits, saccades, and optokinetic nystagmus in the vertical direction, with relatively normal eye movements in the horizontal direction, and ataxia features on finger chase testing, tandem walking, and gait ataxia.

Educational Value: Impairment of vertical eye movements in combination with ataxia, cognitive impairment, and/or psychiatric symptoms in an adult patient should always raise clinical suspicion of Niemann–Pick Type C.

description: SWEET-Cat, a catalogue of Stars With ExoplanETs was originally introduced in 2013, and since then, many more exoplanets were confirmed increasing significantly the number of host stars listed there. A crucial step for a comprehensive understanding of these new worlds is the precise and homogeneous characterization of their host stars. Better spectroscopic stellar parameters along with new results from Gaia eDR3 provide updated and precise parameters for the discovered planets. A new version of the catalogue is now available to the community, whose homogeneity in the derivation of the parameters is key to unravel star-planet connections. Here we review the updated metallicity distributions of stars hosting planets. We present the current status of different planet-host populations (e.g. low-mass planet host stars, Jupiter-like host stars) which provide observational statistical constrains for the theory of planet formation and evolution. Since SWEET-Cat continues to be updated with the new discoveries of exoplanets it could be also very useful for PLATO, in particular it can be used to access the validation of the already known planet-host stars that will be listed in the PLATO Input Catalogue.

description: Background: Akathisia is an inner urge to move a body area with an objective motor component of restlessness. Tardive akathisia (TA) is usually bilateral with a predominant lower-body presentation. We report two patients with an asymmetrical predominantly upper-body involvement.

Case Report: Two young men with history of psychiatric problems and neuroleptic use revealed atypical TA, characterized by asymmetrical and predominantly upper-body involvement. Their main manifestations were rubbing the face, mostly with one hand, accompanied by an inner sensation of restlessness.

Discussion: Our patients are proof that TA can present with asymmetrical and upper-body involvement even with normal brain imaging.

Case Report: An adult patient with cerebrotendinous xanthomatosis exhibited ataxia and palatal tremor in the absence of tendon xanthomas and cataracts.

Discussion: The importance of this case resides on the fact that cerebrotendinous xanthomatosis should be considered as a possible etiology of the syndrome of progressive ataxia with palatal tremor, even in the absence of tendon xanthomas and cataracts. Early diagnosis is critical to the institution of specific treatment with chenodeoxycholic acid.

description: We present a simple method for determining the shape of fundamental domains of generalized modular groups related to Weyl groups of hyperbolic Kac-Moody algebras. These domains are given as subsets of certain generalized upper half planes, on which the Weyl groups act via generalized modular transformations. Our construction only requires the Cartan matrix of the underlying finite-dimensional Lie algebra and the associated Coxeter labels as input information. We present a simple formula for determining the volume of these fundamental domains. This allows us to re-produce in a simple manner the known values for these volumes previously obtained by other methods.

description: We develop an approach to study the entanglement in two coupled harmonic oscillators. We start by introducing an unitary transformation to end up with the solutions of the energy spectrum. These are used to construct the corresponding coherent states through the standard way. To evaluate the degree of the entanglement between the obtained states, we calculate the purity function in terms of the coherent and number states, separately. The result is yielded to two parameters dependance of the purity, which can be controlled easily. Interesting results are derived by fixing the mixing angle of such transformation as π/2. We compare our results with already published work and point out the relevance of these findings to a systematic formulation of the entanglement effect in two coupled harmonic oscillators.

description: Background: Increased depression, hearing loss, dementia, alcoholism, and mortality in essential tremor patients remain unexplained. We investigated whether conditions associated with tremor are linked to chronic stress.

Methods: The FY2013 Veterans Affairs database was queried for 38 selected dual diagnosis combinations in 5,854,223 veterans aged 21–95 years.

Results: Post-traumatic stress disorder, anxiety, and depression were the most common psychiatric diagnoses in tremor patients, with the odds ratio exceeding 2 in all 15-year cohorts. Depending on age, patients with essential tremor were more likely than those without to have obsessive–compulsive disorder, bipolar illness, schizophrenia, use tobacco and abuse alcohol, have hypertension, obesity, hyperlipidemia, diabetes, vitamin D deficiency, coronary and cerebrovascular diseases, congestive heart failure, stroke, asthma, hypothyroidism, irritable bowel syndrome, renal insufficiency, alcoholic liver disease, hearing loss, glaucoma, macular degeneration, migraine, epilepsy, idiopathic polyneuropathy, history of head trauma, and ‘Alzheimer’s dementia. In contrast, lung and colorectal cancer, amyotrophic lateral sclerosis, psychostimulant abuse, and rheumatoid arthritis were not more common.

Discussion: Post-traumatic stress disorder, anxiety, and depression, strongly associated with essential tremor, are known risk factors for poor health habits, tobacco use and alcohol abuse; collectively these are risk factors for vascular disease, with further negative health consequences for multiple organ systems. As essential tremor is associated with all these conditions, we propose that chronic stress is not only responsible for the conditions associated with tremor but in some cases itself directly and indirectly induces essential tremor, so that tremor and poor health share a common cause.

description: This forum is dedicated to the discussion on the social values of Second Language Acquisition (SLA) research and is motivated by talks organized in the Fall of 2018 by Columbia University, Teachers College Center for International Foreign Language Teacher Education (CIFLTE): two talks by Professor Weiguo Zhang of Shandong University and a talk by Professor Lourdes Ortega of Georgetown University. Historically, SLA research has investigated the linguistic and cognitive phenomena of language transfer, staged developments, and systematicity and variability of the learner’s interlanguage. Such inquiry has led to empirical studies that explored the role of one’s internal mechanisms (both language-specific and cognitive), the role of the mother tongue, the role of psychological variables and lastly, the role of the second language (L2) learner’s social and environmental factors. Due to the field’s reliance on drawing inspiration from psycholinguistic traditions, the latter factors of social and environmental influences had typically received little limelight within the SLA community. However, this trend is starting to change as the discussion on the meaning and the significance of social values in language research is beginning to take shape among SLA scholars. A representative case in point is the talks delivered by Professor Zhang and Professor Ortega that highlighted, albeit from different disciplinary perspectives, a shift in perspective on social values in SLA research. This forum will review the role of social values in SLA research as discussed in these talks and consider the role of critical pedagogy in further exploring social values in the field.

description: The measurement of the light scattered from extrasolar planets informs atmospheric and formation models. With the discovery of many hot Jupiter planets orbiting nearby stars, this motivates the development of robust methods of characterisation from follow up observations. In this paper we discuss two methods for determining the planetary albedo in transiting systems. First, the most widely used method for measuring the light scattered by hot Jupiters (Collier Cameron et al.) is investigated for application for typical echelle spectra of a transiting planet system, showing that detection requires high signal-to-noise ratio data of bright planets. Secondly a new Fourier analysis method is also presented, which is model-independent and utilises the benefits of the reduced number of unknown parameters in transiting systems. This approach involves solving for the planet and stellar spectra in Fourier space by least-squares. The sensitivities of the methods are determined via Monte Carlo simulations for a range of planet-to-star fluxes. We find the Fourier analysis method to be better suited to the ideal case of typical observations of a well constrained transiting system than the Collier Cameron et al. method. We apply the Fourier analysis method for extracting the light scattered by transiting hot Jupiters from high resolution spectra to echelle spectra of HD 209458 and HD 189733. Unfortunately we are unable to improve on the previous upper limit of the planet-to-star flux for HD 209458b set by space-based observations. A 1σupper limit on the planet-to-star flux of HD 189733b is measured in the wavelength range of 558.83-599.56 nm yielding ε < 4.5 \times 10-4. Improvement in the measurement of the upper limit of the planet-to-star flux of this system, with ground-based capabilities, requires data with a higher signal-to-noise ratio, and increased stability of the telescope.

description: We investigate the consequences of introducing a set of exotic doublet leptons which couple to the standard model leptons in a minimal way. Through these additional gauge invariant and renormalizable coupling terms, new sources of tree-level flavor changing currents are induced via mixing. In this work, we derive constraints on the parameters that govern the couplings to the exotic doublets by invoking the current low-energy experimental data on processes such as leptonic Z decays, $\ell \rightarrow 3 \ell'$, $\ell \rightarrow \ell' γ$, and $μ$-$e$ conversion in atomic nuclei. Moreover, we have analyzed the role these doublets play on the lepton anomalous magnetic moments, and found that their contribution is negligible.

Creating a sense of belonging for Indigenous students in British Columbia?
Creators: name: Larson, Colleen Edith
Publisher: name: University of British Columbia
Year: 2017

description: This dissertation tells the story of partnership between myself, a doctoral student at UBC Okanagan, the Taku River Tlingit First Nation (TRTFN) and School District 87 (Stikine). Although the research is a partial fulfillment for my doctoral degree, I have attempted to emphasize the partnership aspects of the process throughout the writing of this document. I have been challenged to find ways to word sentences without using the phrase, my research. This was important to me because the first goal of this research is to decolonize research about Indigenous peoples by partnering with the Indigenous people. With regards to the second goal, Indigenous peoples worldwide and Aboriginal peoples in Canada advocate for changes to education for Indigenous students that will nurture Indigenous identity while preparing students and Indigenous communities for a prosperous future. This research supports initiatives to changes education for Indigenous students by sharing information from Indigenous students, parents, and community members about the ways in which Indigenous culture and language in schools can enhance sense of belonging and achievement. The aim of this research is to bridge the gap between European and Indigenous approaches to education through these two goals. To accomplish this, the research follows a Métis methodology based upon principles from Indigenous methodologies, appreciative inquiry, and grounded theory. The results of our research indicate that the children of TRTFN enjoy school, but have challenges to overcome for attendance in school and for access to secondary education. Students in Atlin have a strong sense of belonging to the land, to ancestors, to family, and to community. Students and their families and teachers believe that learning Tlingit culture and language is important to pass knowledge on to future generations. Students enjoy making choices about what they will learn and having opportunities for leadership. Finally, learning Indigenous culture and knowledge benefits all students. This is, of course, my dissertation. However, the learning that I acquired and the story of the research process are a shared journey with my partners in the research, TRTFN and SD87. It is my research for my dissertation, but our research for the community.

Topological quantum phase transitions of attractive spinless fermions in a honeycomb lattice

description: We investigate a spinless Fermi gas trapped in a honeycomb optical lattice with attractive nearest-neighbor interactions. At zero temperature, mean-field theory predicts three quantum phase transitions, two being topological. At low interactions, the system is semi-metallic. Increasing the interaction further, the semi-metal destabilizes into a fully gapped superfluid. At larger interactions, a topological transition occurs and this superfluid phase becomes gapless, with Dirac-like dispersion relations. Finally, increasing again the interaction, a second topological transition occurs and the gapless superfluid is replaced by a different fully gapped superfluid phase. We analyze these different quantum phases as the temperature and the lattice filling are varied.

A hybrid approach for predicting the distribution of vibro-acoustic energy in complex built-up structures

description: Finding the distribution of vibro-acoustic energy in complex built-up structures in the mid-to-high frequency regime is a difficult task. In particular, structures with large variation of local wavelengths and/or characteristic scales pose a challenge referred to as the mid-frequency problem. Standard numerical methods such as the finite element method (FEM) scale with the local wavelength and quickly become too large even for modern computer architectures. High frequency techniques, such as statistical energy analysis (SEA), often miss important information such as dominant resonance behaviour due to stiff or small scale parts of the structure. Hybrid methods circumvent this problem by coupling FEM/BEM and SEA models in a given built-up structure. In the approach adopted here, the whole system is split into a number of subsystems which are treated by either FEM or SEA depending on the local wavelength. Subsystems with relative long wavelengths are modelled using FEM. Making a diffuse field assumption for the wave fields in the short wave length components, the coupling between subsystems can be reduced to a weighted random field correlation function. The approach presented results in an SEA-like set of linear equations which can be solved for the mean energies in the short wavelength subsystems.
Replica analysis of the generalized p-spin interaction glass model

description: We investigate stability of replica symmetry breaking solutions in generalized $p$-spin models. It is shown that the kind of the transition to the one-step replica symmetry breaking state depends not only on the presence or absence of the reflection symmetry of the generalized "spin"-operators $\hat{U}$ but on the number of interacting operators and their individual characteristics.

description: Our main result is that the image of the quantum representation of a central extension of the mapping class group of the genus $g\geq 3$ closed orientable surface at a prime $p\geq 5$ is a Zariski dense discrete subgroup of some higher rank algebraic semi-simple Lie group $\mathbb G_p$ defined over $\Q$. As an application we find that, for any prime $p\geq 5$ a central extension of the genus $g$ mapping class group surjects onto the finite groups $\mathbb G_p(\Z/q\Z)$, for all but finitely many primes $q$. This method provides infinitely many finite quotients of a given mapping class group outside the realm of symplectic groups.

description: This article provides an overview of conversation analytic research that investigates the phenomenon of interlocutors “finishing each other’s sentences,” termed collaborative completion, in everyday conversation. The objective is twofold: (1) by reporting on research that examines the formal features and the social actions of collaborative completions, this paper provides a comprehensive overview of both what this practice looks like and what it can achieve in interaction; and (2) in discussing this particular body of work with respect to the larger topic of how language is studied, the author hopes to demonstrate the power of the CA approach to deepen our understanding of the nature of language and how language is used. The paper first reviews the formal features of collaborative completions, namely its syntactic, paralinguistic, and sequential characteristics. Then, the various social actions that can be accomplished with this practice are discussed. Finally, some important themes and suggested directions for future research are mentioned and contextualized within some of the larger objectives of CA research.

description: We present a systematic study of various ways (top gates, local doping, substrate bias) to fabricate and tune multi-dot structures in silicon nanowire multigate MOSFETs (metal-oxide-semiconductor field-effect transistors). The carrier concentration profile of the silicon nanowire is a key parameter to control the formation of tunnel barriers and single-electron islands. It is determined both by the doping profile of the nanowire and by the voltages applied to the top gates and to the substrate. Local doping is achieved with the realisation of up to two arsenic implantation steps in combination with gates and nitride spacers acting as a mask. We compare nominally identical devices with different implantations and different voltages applied to the substrate, leading to the realisation of both intrinsic and doped coupled dot structures. We demonstrate devices in which all the tunnel resistances towards the electrodes and between the dots can be independently tuned with the control top gates wrapping the silicon nanowire.
