description: This paper discusses a novel fully implicit formulation for a 1D electrostatic particle-in-cell (PIC) plasma simulation approach. Unlike earlier implicit electrostatic PIC approaches (which are based on a linearized Vlasov-Poisson formulation), ours is based on a nonlinearly converged Vlasov-Ampère (VA) model. By iterating particles and fields to a tight nonlinear convergence tolerance, the approach features superior stability and accuracy properties, avoiding most of the accuracy pitfalls in earlier implicit PIC implementations. In particular, the formulation is stable against temporal (CFL) and spatial (aliasing) instabilities. It is charge- and energy-conserving to numerical roundoff for arbitrary implicit time steps. While momentum is not exactly conserved, errors are kept small by an adaptive particle sub-stepping orbit integrator, which is instrumental to prevent particle tunneling. The VA model is orbit-averaged along particle orbits to enforce an energy conservation theorem with particle sub-stepping. As a result, very large time steps, constrained only by the dynamical time scale of interest, are possible without accuracy loss. Algorithmically, the approach features a Jacobian-free Newton-Krylov solver. A main development in this study is the nonlinear elimination of the new-time particle variables (positions and velocities). Such nonlinear elimination, which we term particle enslavement, results in a nonlinear formulation with memory requirements comparable to those of a fluid computation, and affords us substantial freedom in regards to the particle orbit integrator. Numerical examples are presented that demonstrate the advertised properties of the scheme. In particular, long-time ion acoustic wave simulations show that numerical accuracy does not degrade even with very large implicit time steps, and that significant CPU gains are possible.

Subjects: subject: Psychic trauma

description: The evidence is clear about the prevalence of both mental health problems and experiences of trauma among children and youth; therefore, trauma has the potential to impact the mental health of their teachers. This inquiry aimed to provide a space for teachers to explore their experiences with students who suffer from trauma and to bring awareness to their challenges by providing thematic findings based on teachers’ stories and narratives. In my research I explore the questions, “How does student trauma affect teachers’ capacities and capabilities to do their job?” and “How do teachers work through secondary trauma in the classroom?” This study includes the narratives of four participants who have worked with students who have experienced trauma. The interviews indicated that the teachers do believe that their capacity and capability to do their job is impacted by student trauma. This study points to a need to develop trauma-informed practice in schools. The findings strongly suggest that teachers should have basic knowledge about traumatic stress and further professional development which would hopefully help them feel more confident about working with children who have been exposed to trauma. Additionally, some participants in the interviews acknowledged feelings of secondary traumatic stress due to working with students who have had traumatic experiences. The teachers in this study indicated difficulties with emotional involvement. As such, the result of this study points to the importance of paying attention to the emotional burden teachers may experience.

description: Il seguente documento di sviluppo professionale è focalizzato sul tema della fotografia nell’ambito delle arti plastiche. La presenza massiccia delle tecnologie nella società attuale deve essere considerata dal mondo della scuola. Oggi anche i più piccoli, già dalla scuola dell’infanzia, imparano a usare le dita facendole scorrere su uno schermo tattile. La fotocamera è ormai alla portata di tutti, con un semplice telefonino o un tablet chiunque può scattare numerose fotografie. Ma con quale consapevolezza un bambino fa uso della fotocamera? È cosciente che un’immagine, di ogni genere, è una parte della realtà? Fino a che punto è capace di leggere o interpretare il messaggio che essa vuole comunicare? Conosce alcuni semplici trucchi per narrare storie diverse mantenendo lo stesso soggetto? Queste sono alcune delle domande che stanno alla base dell’ideazione del percorso didattico immaginato per una quinta elementare. L’intento è di avvicinare i ragazzi ai principi della fotografia provando a usare l’apparecchio fotografico per realizzare un collage innovativo. Un breve incontro con l’arte vissuto soprattutto come esperienza in grado di suscitare entusiasmo e curiosità: le mani e il pensiero dei bambini sono messi all’opera in modo creativo.
title: Becoming a holistic teacher: how we can respectfully blend Indigenous and Euro-Canadian pedagogies in rural communities

description: In taking steps toward reconciliation, BC’s Ministry of Education, schools, and educators are responding to the call to blend Indigenous and Euro-Canadian pedagogies in the current K-12 curriculum in order to address the inequities in education systems, particularly for Indigenous students. However, many educators, particularly within the unique context of rural regions, are unsure how to effectively blend these differing learning models, and with that, how to best meet all their students’ needs. So how can rural teachers respectfully blend Indigenous and Euro-Canadian pedagogies into their practice? Based on the theoretical frameworks for blending Indigenous and Euro-Canadian pedagogies which are explored in the review of the literature in this document, I posit that one way this can be achieved is through becoming a Holistic Educator, which is the practice of teaching with a focus on interconnectedness and educating the whole learner rather than the sum of their parts. Given that many educators in rural contexts are unsure of how to blend these two pedagogies, I have developed a blog-style website called HolisticTeacher.ca. With the overarching intent of demonstrating what I have learned from the literature, including studies specifically in rural communities, it is designed for K-12 teachers and parents of young children to be able to use as a resource to gain inspiration and confidence to holistically lead their students in learning experiences that may help us decolonize education.

description: Let $C$ denote a closed convex cone $C$ in $\mathbb{R}^d$ with apex at 0. We denote by $\mathcal{E}'(C)$ the set of distributions having compact support which is contained in $C$. Then $\mathcal{E}'(C)$ is a ring with the usual addition and with convolution. We give a necessary and sufficient analytic condition on $\hat{f}_1,..., \hat{f}_n$ for $f_1,...,f_n \in \mathcal{E}'(C)$ to generate the ring $\mathcal{E}'(C)$. (Here $\hat{\cdot}$ denotes Fourier-Laplace transformation.) This result is an application of a general result on rings of analytic functions of several variables by Hörmander. En route we answer an open question posed by Yutaka Yamamoto.

description: The purpose of this thesis is to identify where the author, who is a white, cisgender, Christian woman and administrator, and who comes from a place of privilege, belongs in the process of transforming equitable learning environments. Through a reflective analysis using constructive developmental theory, the author shares her journey and recognition of shifting her identity from ally to co-conspirator. This study uses autoethnographic entries and dialogic engagement to identify how white privilege, systemic racism, and the colonial narrative continue to impact the system and create inequity within education. This thesis is in response to the urgings of educational leaders and authors who encourage white privileged people to identify how their racial biases impact marginalized learners. This study is also a personal response to answer the Truth and Reconciliation Calls to Action. The author invites the reader to situate themselves within the author’s journey and paddle forward as a co-conspirator with the BIPOC community and other marginalized learners.

description: L’attuale Patinoire du Voyeboeuf, non può più essere casa per l’ Hockey Club Ajoie. Inaugurata nel 1973 non nasconde il passare del tempo; in facciata sono ben visibili i danni inflitti dagli eventi metereologici che l’hanno interessata e i problemi legati alla copertura non consentono la corretta realizzazione e il mantenimento del ghiaccio della pista. In generale lo stato di conservazione dell’edificio non è all’altezza del Club che ha grandi ambizioni in prima lega. L’obbiettivo è quindi, nell’ambito della realizzazione della nuova costruzione, quello di realizzare la copertura in carpenteria in legno, garantendo un’altezza libera sopra la pista di 12m.

description: We report the discovery of several large "propeller" moons in the outer part of Saturn's A ring, objects large enough to be followed over the 5-year duration of the Cassini mission. These are the first objects ever discovered that can be tracked as individual moons, but do not orbit in empty space. We infer sizes up to 1--2 km for the unseen moonlets at the center of the propeller-shaped structures, though many structural and photometric properties of propeller structures remain unclear. Finally, we demonstrate that some propellers undergo sustained non-keplerian orbit motion. (Note: This arXiv version of the paper contains supplementary tables that were left out of the ApJL version due to lack of space).

title: South Korean middle and high school learner voices: a narrative and autoethnographical study into learning experiences in Korean public schools and transitions into alternative streams
Creators: name: Young, James
Publisher: name: Electronic version published by Vancouver Island University
Year: 2021
Subjects: subject: Korean students

description: South Korean middle and high school learners and their families sometimes choose to transition from Korean public school to less mainstream alternative educational options. The defining public school experiences factoring into choosing alternative forms of education are explored in this study. Previous studies provide significant amounts of quantitative data pointing to alarming rates of anxiety, depression, and suicidal ideations among Korean middle and high school learners associated with academic and social pressures. This study’s goal is to supplement this data by providing a more humanistic approach to understanding what these academic and social pressures looked and felt like from individual learner perspectives. Data was collected through open-ended interview questions with recently graduated Korean high school learners, who graduated outside a traditional Korean public school. Interview responses became shaped into co-constructed narratives, with an autoethnographical reflection from my own experiences teaching Korean transitional learners. Contrary to assumption, the public school experiences expressed by participants in motivating them to transition reveal common threads related to being relegated as “outsiders” among their peers, not academic excesses. Participants’ strong emotional memories primarily focused on negative social interactions with peers, rather than the pressure to do well academically. The role of traditional Confucian educational philosophy in promoting exceptionality in not only academic, but social spheres, also revealed itself through interview responses. In better understanding what Korean learners particularly bring with them to their alternative learning environments (culturally, socially, emotionally, and academically), educational stakeholders can be better prepared in providing healthy transitional experiences.

description: Grothendieck inequalities are fundamental inequalities which are frequently used in many areas of mathematics and computer science. They can be interpreted as upper bounds for the integrality gap between two optimization problems: a difficult semidefinite program with rank-1 constraint and its easy semidefinite relaxation where the rank constrained is dropped. For instance, the integrality gap of the Goemans-Williamson approximation algorithm for MAX CUT can be seen as a Grothendieck inequality. In this paper we consider Grothendieck inequalities for ranks greater than 1 and we give two applications: approximating ground states in the n-vector model in statistical mechanics and XOR games in quantum information theory.

description: The basal ganglia play an important role in a variety of functions including decision making and action selection mainly based on input from cortex, thalamus and the dopamine system. Striatum is the input stage of the basal ganglia. Here we present a new approach to model the postsynaptic currents mediated by NMDA or AMPA receptors which allows a more accurate description of them. Then we model the extrinsic inputs from cortex and thalamus to the different populations of striatal neurons (striatal projection neurons (dSPNs and iSPNs); cholinergic (ChIN), fast-spiking (FS), and low-threshold spiking (LTS) interneurons). Synapses are critical when investigating microcircuit functions and dynamics, therefore it is necessary to have a computationally efficient and accurate framework to model them. Here we are improving such a pipeline using morphologically detailed neurons. Our method is generic and hence applicable to any brain region. We are working on the integration of these models into large scale networks as part of our ongoing effort to create detailed simulations of the entire striatum.

description: Absorption spectra of Ni$^{2+}$ ions in 22WO$_3$--78TeO$_2$ tungstate-tellurite glass were studied and Ni$^{2+}$ extinction coefficient spectral dependence was derived in the 450 -- 2700 nm wavelength range. Computer modeling of the glass structure proved Ni$^{2+}$ ions to be in trigonal-distorted octahedral environment in the tungstate-tellurite glass. Tanabe-Sugano diagram for such an environment was calculated and good description of the observed spectrum of Ni$^{2+}$ ion was obtained. Basing on both absorption spectral range width and the extinction coefficient, nickel should be considered among the most strongly absorbing impurities in the tellurite glasses.

description: The work is devoted to the studying the effect of amino acid substitutions in the C-domain of the Sup35 protein on its functional activity. A method for isolating wild-type Sup35p and mutant variants, as well as Sup45 protein, are described. The phenotypic manifestations of sup35 mutations in the presence of the full-length SUP35 gene or its fragment encoding the C-domain were compared. The GTPase activity of the C-domain of the wild type Sup35 protein and mutant variants was measured. The data obtained allow us to consider the missense mutations under study as the cause of a violation of translation termination and incompatibility of mutant Sup35 proteins with the factor [PSI+].

description: The manipulation and crafting of our physical environmentis a fundamental and defining human characteristic. Thestandardized and mass produced urban civilizations we inhabit are becoming increasingly impersonal.

As we search for deeper connections and forge meaningful relationships with our environment we face new challenges of integrating the intangible digital content on which we place an increasing importance.

Through a process of enhancing and exaggerating the interaction process, the physicality of these digital devices may better describe the relationship between individuals and their digital content.

I endeavor to create objects that represent the intangible digitalcontent they contain, in the hope they may take more aesthetic andmeaningful forms to better integrate them into the most personal of environments, our homes.

Through this paper I will describe how I have sought to represent one of the most important aspects of individuality and self, expressed within our homes, memory.

description: Bases of finite-dimensional Hilbert spaces (in dimension d) of relevance for quantum information and quantum computation are constructed from angular momentum theory and su(2) Lie algebraic methods. We report on a formula for deriving in one step the (1+p)p qupits (i.e., qudits with d = p a prime integer) of a complete set of 1+p mutually unbiased bases in C^p. Repeated application of the formula can be used for generating mutually unbiased bases in C^d with d = p^e (e > or = 2) a power of a prime integer. A connection between mutually unbiased bases and the unitary group SU(d) is briefly discussed in the case d = p^e.

description: Thinking Keeping is a creative, practice-based enquiry into the irreversible act of ‘breaking in’ to a sealed package. Breaking open a product’s packaging structures the user’s first experiences of owning the product, and reinforces perceptions of the product’s newness, perfection and desirability. It is a pivotal stage in the emotional lifetime of a product.

Through creative methods we are subverting the experience of ‘breaking the seal’, by applying it to products that have already been owned and used. Our enquiry raises questions about the potential of packaging to overcome barriers to reuse, to help construct meaningful lasting relationships with products, and to challenge the desire for newness. We intend to expose contradictions in how consumers value, keep and destroy packaging. The research brings a new angle to research relating design to practices of keeping things and sustainable consumption (e.g. Chapman 2005, Fisher and Shipton 2010, Schifferstein et al 2008).

Design can play a key role in influencing consumers’ relationships totheir possessions, and designers are in a position to propose powerful ways of rethinking the relationship through creative, practice-based approaches. Our explorations are structured around sketching, prototyping, and data collection via exhibition. Working without the constraints of a commercial brief means that we can develop concepts that subvert expectations, and whose ambiguity prompts reflection and speculation.

Thinking Keeping is a collaboration between a product designer, a packaging designer, and a jewellery designer.

description: Using special technique of expanding ratio of densities in an infinite series of polynomials orthogonal with respect to one of the densities, we obtain simple, closed forms of certain kernels built of the so called Al-Salam-Chihara (ASC) polynomials. We consider also kernels built of some other families of polynomials such as the so called big continuous q-Hermite polynomials that are related to the ASC polynomials. The constructed kernels are symmetric and asymmetric. Being the ratios of the densities they are automatically positive. We expand also reciprocals of some of the kernels, getting nice identities built of the ASC polynomials involving 6 variables like e.g. formula (nice). These expansions lead to asymmetric, positive and summable kernels. The particular cases (referring to q=1 and q=0) lead to the kernels build of certain linear combinations of the ordinary Hermite and Chebyshev polynomials.
Tidal dissipation compared to seismic dissipation: in small bodies, in earths, and in superearths

description: While the seismic quality factor and phase lag are defined solely by the bulk properties of the mantle, their tidal counterparts are determined both by the bulk properties and self-gravitation of a body as a whole. For a qualitative estimate, we model the body with a homogeneous sphere and express the tidal phase lag through the lag in a sample of material. Although simplistic, our model is sufficient to understand that the lags are not identical. The difference emerges because self-gravitation pulls the tidal bulge down. At low frequencies, this reduces strain and makes tidal damping less efficient in larger bodies. At high frequencies, competition between self-gravitation and rheology becomes more complex, though for sufficiently large superearths the same rule works: the larger the body, the weaker tidal damping in it. Being negligible for small terrestrial planets and moons, the difference between the seismic and tidal lagging (and likewise between the seismic and tidal damping) becomes very considerable for superearths. In those, it is much lower than what one might expect from using a seismic quality factor. The tidal damping rate deviates from the seismic damping rate especially in the zero-frequency limit, and this difference takes place for bodies of any size. So the equal in magnitude but opposite in sign tidal torques, exerted on one another by the primary and the secondary, go smoothly through zero as the secondary crosses the synchronous orbit. We describe the mantle rheology with the Andrade model, allowing it to lean towards the Maxwell model at the lowest frequencies. To implement this additional flexibility, we reformulate the Andrade model by endowing it with a free parameter which is the ratio of the anelastic timescale to the viscoelastic Maxwell time of the mantle. Some uncertainty in this parameter's frequency-dependence does not influence our principal conclusions.

description: The Modified Chaplygin Gas (MCG) model belongs to the class of a unified models of dark energy (DE) and dark matter (DM). It is characterized by an equation of state (EoS) $p_c = Bρ- A/ρ^α$, where the case $B=0$ corresponds to the Generalized Chaplygin Gas (GCG) model. Using a perturbative analysis and power spectrum observational data we show that the MCG model is not a sucessful candidate for the cosmic medium unless $B=0$. In this case, it reduces to the usual GCG model.

description: This paper presents a set of exploits an adversary can use to continuously spy on most BitTorrent users of the Internet from a single machine and for a long period of time. Using these exploits for a period of 103 days, we collected 148 million IPs downloading 2 billion copies of contents. We identify the IP address of the content providers for 70% of the BitTorrent contents we spied on. We show that a few content providers inject most contents into BitTorrent and that those content providers are located in foreign data centers. We also show that an adversary can compromise the privacy of any peer in BitTorrent and identify the big downloaders that we define as the peers who subscribe to a large number of contents. This infringement on users' privacy poses a significant impediment to the legal adoption of BitTorrent.

description: This work is devoted to the properties of slot antennas. The aim of the work is to study the theoretical material associated with antennas and use the knowledge gained to derive formulas that describe the properties of slot antennas.
Such knowledge was obtained as: the principle of permutation duality (the Pistolkors duality principle), the input impedance of a symmetric slotted vibrator and the propagation constant of a current wave along a thin wire located at the in-terface between two media. This theory was enough to calculate the parameters of slot antennas, which was done in my work.
Simplifying response surface analysis : proposing a new model specification
Creators: name: Can, Phuong Quynh

description: Researchers in psychology are often interested in questions of whether the magnitude of the similarity or difference between two measures or variables is related to an outcome of interest. These types of questions usually address theoretical issues in psychology that are linked with optimization. Such questions, for example, are whether a certain extent of similarity or difference between two constructs predicts the optimal levels of dyadic satisfaction, attraction, relationships, intrapersonal consistency; or what are the ideal levels of similarity or difference of person-environment fit on health outcomes, just to name a few. Methods such as difference scores and distance measures have been proposed and are commonly used to examine such research questions. However, these measures, when used in isolation, are restrictive and make strong modeling assumptions. More recently, response surface analysis (RSA) methods have been adapted to provide more modeling flexibility and less restrictive models to examine questions of whether (dis)similarity are related to outcomes of interest. The RSA model uses two predictors instead of one which preserves data dimensionality and allows each predictor to have both linear, curvilinear, and interactive relationship with the outcome. Given the functionality and utility of RSA, we advocate its use in similarity research while proposing to conceptualize the modeling of (dis)similarity measures in a simpler way for researchers who currently use or plan to use RSA to address such questions. We propose that researchers use an average (A) and a half of a difference (D) instead of the two original predictors. This new model specification has several advantages. First, it helps researchers to define (dis)similarity coefficients, the parameters that researchers of this topic are truly interested in, more precisely. Second, this new model specification utilizes two orthogonal variables, unlike the original model that uses two predictors that are mostly correlated with each other, thus avoiding multicollinearity issues altogether. Third, this usage allows researchers to interpret (dis)similarity coefficients on a response surface graph more easily. We demonstrated the incremental benefits of the proposed reparameterization approach through mathematical proofs and an empirical example.

description: We propose a modified power method for computing the subdominant eigenvalue $λ_2$ of a matrix or continuous operator. Here we focus on defining simple Monte Carlo methods for its application. The methods presented use random walkers of mixed signs to represent the subdominant eigenfuction. Accordingly, the methods must cancel these signs properly in order to sample this eigenfunction faithfully. We present a simple procedure to solve this sign problem and then test our Monte Carlo methods by computing the $λ_2$ of various Markov chain transition matrices. We first computed ${λ_2}$ for several one and two dimensional Ising models, which have a discrete phase space, and compared the relative efficiencies of the Metropolis and heat-bath algorithms as a function of temperature and applied magnetic field. Next, we computed $λ_2$ for a model of an interacting gas trapped by a harmonic potential, which has a mutidimensional continuous phase space, and studied the efficiency of the Metropolis algorithm as a function of temperature and the maximum allowable step size $Δ$. Based on the $λ_2$ criterion, we found for the Ising models that small lattices appear to give an adequate picture of comparative efficiency and that the heat-bath algorithm is more efficient than the Metropolis algorithm only at low temperatures where both algorithms are inefficient. For the harmonic trap problem, we found that the traditional rule-of-thumb of adjusting $Δ$ so the Metropolis acceptance rate is around 50% range is often sub-optimal. In general, as a function of temperature or $Δ$, $λ_2$ for this model displayed trends defining optimal efficiency that the acceptance ratio does not. The cases studied also suggested that Monte Carlo simulations for a continuum model are likely more efficient than those for a discretized version of the model.

description: Previous field studies monitoring small groups of participants showed that heat stress in the electrical utilities industry may be detrimental to worker health and safety. Our aim in this study was to characterize heat stress and strain in electrical utilities workers across North America. A total of 428 workers in the power generation, transmission, and distribution industry across 16 U.S. states and 3 Canadian Provinces completed a two-part on-line questionnaire anonymously. The first part comprised 13 general questions on the employee’s workplace location, role in the organization, years of experience, general duties, average work shift duration, and other job-related information. It also included two questions on self-reported heat stress. The second part consisted of the “Heat Strain Score Index” (HSSI), a validated questionnaire which evaluates heat stress at the workplace as “safe level” (score ≤13.5: worker experiences no/low heat strain), “caution level” (score 13.6 to 18.0: moderate risk for heat strain), and “danger level” (score >18.0: high risk for heat strain). In addition to the survey, we obtained meteorological data from weather stations in proximity (12.3 ± 12.2 km) to the work locations. Based on the HSSI, 32.9%, 22.3%, and 44.4% of the responders’ workplaces were diagnosed as “safe level,” “caution level,” and “danger level,” respectively. The HSSI varied significantly depending on the occupation from 4.9 ± 3.2 in contact center workforce to 19.1 ± 5.4 in mechanics (p p p
