The nature, development and implications of the 'curse of knowledge' in childhood
Creators: name: Ghrear, Siba
Publisher: name: University of British Columbia
Year: 2021

description: Our ability to reason about the perspectives of others is associated with many positive life outcomes (e.g., better interpersonal relationships). Unfortunately, when reasoning about the perspectives of others, we are often biased by our own knowledge (i.e., the curse of knowledge). The curse of knowledge is a cognitive bias that limits our ability to reason about less- knowledgeable perspectives. It leads to overestimations of what others know and clouds our judgements about their beliefs. Critically, this bias is prevalent across various contexts, and it affects our social reasoning across the lifespan. Previous research demonstrated the effects of the bias on children’s social reasoning, however there are several critical theoretical questions that remain unanswered. For instance, is the bias universal among children? I find support for the universality of the bias, in Chapter 2, by showing that even children of a nomadic pastoralist tribe, the Turkana, show the bias. Furthermore, in Chapter 3, I examine how age-related changes in the bias can affect young children’s performance on a widely used measure of Theory of Mind—a false belief task. I examine this question in two experiments; one showing that younger children are more accurate at reasoning about other perspectives when the curse of knowledge is minimized. The other experiment showing that children’s inferences are biased by their knowledge but that minimizing the bias does not improve performance. I discuss potential reasons for the discrepancy between experiments. Finally, I examine two accounts on the mechanisms underlying the curse of knowledge. In Chapter 4, I provide evidence that fluency misattribution (i.e., the tendency to attribute the fluency in processing a stimulus to an inaccurate source) is necessary for the bias to occur. Chapter 5 summarizes my findings, discusses their implications, and highlights avenues for future research.
Phenomenological Study of Decoherence in Solid-State Spin Qubits due to Nuclear Spin Diffusion

description: We present a study of the prospects for coherence preservation in solid-state spin qubits using dynamical decoupling protocols. Recent experiments have provided the first demonstrations of multipulse dynamical decoupling sequences in this qubit system, but quantitative analyses of potential coherence improvements have been hampered by a lack of concrete knowledge of the relevant noise processes. We present simulations of qubit coherence under the application of arbitrary dynamical decoupling pulse sequences based on an experimentally validated semiclassical model. This phenomenological approach bundles the details of underlying noise processes into a single experimentally relevant noise power spectral density. Our results show that the dominant features of experimental measurements in a two-electron singlet-triplet spin qubit can be replicated using a $1/ω^{2}$ noise power spectrum associated with nuclear-spin-flips in the host material. Beginning with this validation we address the effects of nuclear programming, high-frequency nuclear-spin dynamics, and other high-frequency classical noise sources, with conjectures supported by physical arguments and microscopic calculations where relevant. Our results provide expected performance bounds and identify diagnostic metrics that can be measured experimentally in order to better elucidate the underlying nuclear spin dynamics.

Magnetization Dissipation in Ferromagnets from Scattering Theory

description: The magnetization dynamics of ferromagnets are often formulated in terms of the Landau-Lifshitz-Gilbert (LLG) equation. The reactive part of this equation describes the response of the magnetization in terms of effective fields, whereas the dissipative part is parameterized by the Gilbert damping tensor. We formulate a scattering theory for the magnetization dynamics and map this description on the linearized LLG equation by attaching electric contacts to the ferromagnet. The reactive part can then be expressed in terms of the static scattering matrix. The dissipative contribution to the low-frequency magnetization dynamics can be described as an adiabatic energy pumping process to the electronic subsystem by the time-dependent magnetization. The Gilbert damping tensor depends on the time derivative of the scattering matrix as a function of the magnetization direction. By the fluctuation-dissipation theorem, the fluctuations of the effective fields can also be formulated in terms of the quasistatic scattering matrix. The theory is formulated for general magnetization textures and worked out for monodomain precessions and domain wall motions. We prove that the Gilbert damping from scattering theory is identical to the result obtained by the Kubo formalism.

Connecting observations of the first galaxies and the Epoch of Reionisation

Publisher: name: Zenodo

description: Our knowledge of the statistics high redshift galaxies responsible for reionising the Universe is constantly improving and will take yet another important step forward with future facilities. At the same time, the upper limits on the EoR 21cm power spectrum are continually falling, with a firm measurement from SKA-low being a certainty in coming years. In order to maximise what we can learn from these two complimentary observational datasets, we need to be able to model them together, self-consistently. In this talk, I will present insights into the connection between early galaxy formation and the EoR gained from the DRAGONS suite of semi-analytic and hydrodynamic galaxy formation simulations. Using these we find that the steep faint end slope of the the high-redshift galaxy UV luminosity function extends well beyond current observational limits, indicating that only ~50% of the ionising photons available for reionisation have been observed at z<7. I will also demonstrate how the topology of reionisation and associated 21cm signal is sensitive to the properties of high-z galaxies, and discuss how SKA-low, in tandem with other future facilities, will allow us to discriminate between different galaxy formation scenarios.

description: During the search for counterparts of very-high-energy gamma-ray sources, we serendipitously discovered large, extended, low surface brightness emission from PWNe around pulsars with the ages up to ~100 kyrs, a discovery made possible by the low and stable background of the Suzaku X-ray satellite. A systematic study of a sample of 8 of these PWNe, together with Chandra datasets, has revealed us that the nebulae keep expanding up to for ~100 kyrs, although time scale of the synchrotron X-ray emission is only ~60 yr for typical magnetic fields of 100 microG. Our result suggests that the accelerated electrons up to ~80 TeV can escape from the PWNe without losing most energies. Moreover, in order to explain the observed correlation between the X-ray size and the pulsar spindwon age, the magnetic field strength in the PWNe must decrease with time.

description: We point out that the quartic cumulant (and kurtosis) of the order parameter fluctuations is universally negative when the critical point is approached on the crossover side of the phase separation line. As a consequence, the kurtosis of a fluctuating observable, such as, e.g., proton multiplicity, may become smaller than the value given by independent Poisson statistics. We discuss implications for the Beam Energy Scan program at RHIC.

MUSEQuBES CGM Surveys: From Low-z Star-forming Galaxies to High-z Lyman-alpha Emitters

description: Gas accretion and galactic winds are the two most important and yet the most poorly understood ingredients of galaxy evolution models. The physical/chemical conditions of the circumgalactic medium (CGM-- a dynamic, complex, multiphase gas reservoir surrounding galaxies) retain imprints of gas accretion and galactic winds. Moreover, it is now well-established that the metal-enriched, ionized CGM harbours gas and metal masses comparable to those in galaxies themselves and can account for the "missing baryons" in galaxies. Consequently, the CGM has received significant attention from both the theoretical and observational astronomical communities. To this end, we are conducting two major, and by far the largest, surveys on the CGM using ~120 hours of MUSE GTO observations. Our high-z (z > 3) sample comprises ~100 Lyman alpha emitters and the low-z (z < 1) sample comprises ~300 low-mass, star-forming galaxies. We use high S/N spectra of background quasars, obtained with the VLT/UVES (for high-z) and HST/COS (for low-z), to study their CGM using absorption line spectroscopy. An overview of the initial main results of these surveys will be presented in the talk. In particular, the dependence of the CGM properties on the SFR, stellar mass, impact parameter, and on redshift will be discussed.

Finding new pulsars using CHIME/FRB single pulse events
Creators: name: Dong, Fengqiu
Publisher: name: University of British Columbia
Year: 2021

description: Pulsars are compact objects which are remnants of once-massive stars. Most are lighthouses in radio frequencies, and studying them has led to significant discoveries of exoplanets, gravitational waves, and fundamental physics theories. An ongoing research area is the source of pulsar emission and, in turn, the strange way telescopes see some pulsars. These include intermittent pulsars and Rotating Radio Transients (RRATs) i.e. ones that turn on for some time but remain quiet otherwise. While the study of pulsars stretches back to 1967, a more contemporary discovery is that of Fast Radio Bursts (FRBs). The discovery in 2007 led to a burgeoning field in radio astronomy, which has enticed many current-generation telescopes. The Canadian Hydrogen Intensity Mapping Experiment (CHIME) is among the bank of telescopes that have been commissioned to find FRBs. This thesis addresses the development and deployment of a novel pipeline for finding new pulsars from galactic and extragalactic single-pulse events. We employ the vast astronomical database collected by the aptly named the CHIME/FRB collaboration over 29 months. The majority of the work was to sort through the CHIME/FRB database for RFI and known pulsars before implementing an unsupervised machine learning algorithm, DBSCAN. DBSCAN made clusters of transient astronomical events which are checked against known pulsars in extant catalogs before being followed up by a second CHIME backend instrument, CHIME/Pulsar. The process has led to 144 candidates, with 12 confirmed new pulsars. Many of the pulsars discovered are RRATs, objects that are atypical for a pulsar in that the pulsed emission is sporadic and intermittent. The continued study of RRATs have the potential to elucidate their intermittency and, by extension, the emission mechanism for pulsars. Thus adding to the current ~120 known RRATs will enable pulsar astronomers to make more substantial claims regarding the estimated ~10⁵ RRATs in the Milky Way Galaxy.

description: The present study reports radiation-chemical yields of 2.5-diaminoimidazolone (Iz) derivatives in X-irradiated phosphate-buffered solutions of guanosine and double-stranded DNA. Various gassing conditions (air, N20/O2 (4:1), N2O, vacuum) were employed to elucidate the contribution of several alternative pathways leading to Iz in reactions initiated by hydroxyl radical attack on guanine. In all systems, Iz was identified as the second by abundance guanine degradation product after 8-oxoguanine, formed in 1:5 (guanosine) and 1:3.3 (DNA) ratio to the latter in air-saturated solutions. Experimental data strongly suggest that the addition of molecular oxygen to the neutral guanine radical G(-H)• plays a major in Iz production in oxygenated solutions of double-stranded DNA while in other systems it may compete with recombination of G(-H)• with superoxide and/or alkyl peroxyl radicals. The production of Iz through hydroxyl radical attack on 8-oxoguanine was also shown to take place although the chemical yield of Iz (ca 6%) in this process is too low to compete with the other pathways. The linearity of Iz accumulation with dose also indicates a negligible contribution of this channel to its yield in all systems.

description: We consider a model of dark energy/matter unification based on a k-essence type of theory similar to tachyon condensate models. Using an extension of the general relativistic spherical model which incorporates the effects of both pressure and the acoustic horizon we show that an initially perturbative k-essence fluid evolves into a mixed system containing cold dark matter like gravitational condensate in significant quantities.

Galaxy morphology, quenching, and mergers in the cluster environment

description: Based on the catalogue from the KASI-Yonsei Deep Imaging Survey of Clusters targeting 14 clusters at 0.015 < z < 0.144, we introduce our findings on galaxy morphology, colour, and visual features generated by galaxy mergers. We find a clear trend between morphological content and cluster velocity dispersion. However, a fraction of lenticular galaxies is nearly constant over cluster-centric distance implying that the major morphological transformation from spirals to lenticulars would be pre-processed before the galaxy accretion into the cluster environment. We find that 20 per cent of our cluster sample show signatures of recent mergers. Galaxies with merger features are populated more on blue colour than their counterparts. Our results support a scenario that the merger events that made the features have preceded the galaxy accretion into the cluster environment. We conclude that mergers affect a cluster population mainly through the pre-processing on recently accreted galaxies.

description: Instructors of statistics who teach non-statistics majors possess varied academic backgrounds, and hence it is reasonable to expect variability in their content knowledge, and pedagogical approach. The aim of this study was to determine the specific course(s) that contributed mostly to instructors' understanding of statistics. Courses reported were described as advanced or graduate level, and classified as application-based, math, multivariate, probability, and research. The majority, 9 (56%) attributed their understanding of statistics to either an application-based or research course, and of those, 7 (44%) reported negative feelings about their introductory courses. These findings underscore the importance of authentic activities, and constructivist pedagogy toward facilitating statistical literacy. Research is needed to determine the effect of instructors' academic preparation on their knowledge, attitudes, and practices.

What drives stellar population evolution?

description: The stellar population of a galaxy contains a record of its star formation and assembly history, making it an important area of research to develop our understanding of galaxy formation and evolution. We present two works, the first focussing on early-type galaxies (ETGs), the second on late-types (LTGs). These works aim to understand the link between the overall structure and dynamics of a galaxy, and the evolution of the stars within it. Currently, the well-established correlations between the mass of a galaxy and the properties of its stars are considered evidence for mass driving the evolution of the stellar population. However, for our sample of 625 early-type galaxies (ETGs) with integral-field spectroscopy from the SAMI Galaxy Survey, compared to correlations with mass, the color—gravitational potential ($\Phi$), [Z/H]--$\Phi$, and age—surface density ($\Sigma$) relations show both smaller scatter and less residual trend with galaxy size. These results lead us to the following inferences: (1) the color--$\Phi$ diagram is a more precise tool for determining the developmental stage of the stellar population than the conventional color--$M$ diagram; and (2) gravitational potential is the primary regulator of global stellar metallicity, via its relation to the gas escape velocity. More recently, we've extended this research to investigate the stellar populations of late-type galaxies (LTGs) using single-fibre spectra from the Sloan Digital Sky Survey.

description: Il presente lavoro vuole indagare come l’utilizzo di controversie nell’insegnamento della geografia permetta di sviluppare una cittadinanza attiva. Per testare questa ipotesi è stato proposto un gioco di simulazione, in una classe di Seconda Media, inerente alla votazione popolare “per imprese responsabili – a tutela dell'essere umano e dell'ambiente”. Per analizzare i risultati è stata utilizzata una metodologia qualitativa, ossia è stata effettuata un’osservazione del gioco di simulazione e un’analisi per tematiche degli elaborati scritti che gli allievi hanno svolto al termine dell’attività. I dati raccolti mostrano che proporre delle sequenze didattiche che trattino delle controversie permette agli allievi di sviluppare delle competenze legate alla comunicazione, alla collaborazione e al pensiero riflessivo e critico. Inoltre, presentare delle questioni autentiche e reali, vicine al vissuto degli allievi, permette loro di costruirsi un’identità di cittadini consapevoli della società che li circonda e capaci di argomentare le proprie posizioni. Questo processo permette agli allievi di diventare da agenti passivi e attori attivi. Concludendo, è importante sottolineare come in una società pluralista e democratica sia fondamentale che la scuola ponga gli allievi di fronte a sfide autentiche, allenandoli così a riflettere criticamente sulla realtà spaziale e sociale che li circonda.

description: We present results from continued Chandra X-ray imaging and spectroscopy of a flux-limited sample of flat spectrum radio-emitting quasars with jet-like extended structure. X-rays are detected from 24 of the 39 jets observed so far. We compute the distribution of alpha_rx, the spectral index between the X-ray and radio bands, showing that it is broad, extending at least from 0.8 to 1.2. While there is a general trend that the radio brightest jets are detected most often, it is clear that predicting the X-ray flux from the radio knot flux densities is risky so a shallow X-ray survey is the most effective means for finding jets that are X-ray bright. We test the model in which the X-rays result from inverse Compton (IC) scattering of cosmic microwave background (CMB) photons by relativistic electrons in the jet moving with high bulk Lorentz factor nearly along the line of sight. Depending on how the jet magnetic fields vary with z, the observed X-ray to radio flux ratios do not follow the redshift dependence expected from the IC-CMB model. For a subset of our sample with known superluminal motion based on VLBI observations, we estimate the angle of the kpc-scale jet to the line of sight by considering the additional information in the bends observed between pc- and kpc-scale jets. These angles are sometimes much smaller than estimates based on the IC-CMB model with a Lorentz factor of 15, indicating that these jets may decelerate significantly from pc scales to kpc scales.

description: A significant observational effort has been directed to unveil the nature of the so-called dark energy. However, given the large number of theoretical possibilities, it is possible that such a task cannot be performed on the basis only of the observational data. In this article we discuss some thermodynamic properties of this energy component by assuming that its constituents are massless quanta with a general time-dependent equation-of-state parameter $ω(z)=ω_0 + ω_a f(z)$, where $ω_0$ and $ω_a$ are constants and $f(z)$ may assume different forms. We show that very restrictive bounds can be placed on the $w_0$ - $w_a$ space when current observational data are combined with the thermodynamic constraints derived.

description: Il mio lavoro di tesi si è svolto su due anni scolastici con una classe di prima, poi seconda media, focalizzandosi sull'integrazione di strumenti digitali nelle lezioni di scienze naturali e matematica. Nel primo anno, abbiamo utilizzato la piattaforma phaenonet.ch per osservare e registrare le fasi fenologiche delle piante, arricchendo così lo studio delle scienze naturali. Nel secondo anno, abbiamo sfruttato i risultati delle registrazioni dei dati di PhaenoNet per le lezioni di matematica nell’ambito della lettura e interpretazione di grafici. L'uso di PhaenoNet ha creato un ambiente di apprendimento coinvolgente e naturale favorendo il consolidamento delle competenze scientifiche e matematiche degli studenti. L'interazione con gli strumenti digitali ha reso l'apprendimento piacevole e coinvolgente, incoraggiando gli studenti a essere attivi e responsabili nel loro percorso di crescita. Questa tesi dimostra l'efficacia dell’approccio interdisciplinare basato sulle discipline MINT nel motivare gli studenti a immergersi nei temi scientifici e matematici. Relatore: Alessio Carmine.

description: For packings of hard but not perfectly rigid particles, the length scales that govern the packing geometry and the contact forces are well separated. This separation of length scales is explored in the force network ensemble, where one studies the space of allowed force configurations for a given, frozen contact geometry. Here we review results of this approach, which yields nontrivial predictions for the effect of packing dimension and anisotropy on the contact force distribution $P(f)$, the response to overall shear and point forcing, all of which can be studied in great numerical detail. Moreover, there are emerging analytical approaches that very effectively capture, for example, the form of force distributions.

Nonlinear mixed-effects models for HIV viral load trajectories before and after antiretroviral therapy interruption, incorporating left censoring
Creators: name: Gao, Sihaoyu
Publisher: name: University of British Columbia
Year: 2021

description: Longitudinal studies are common in biomedical research, such as an HIV study. In an HIV study, the viral decay during an anti-HIV treatment and the viral rebound after the treatment is interrupted can be viewed as two longitudinal processes, and they may be related to each other. In this thesis, we investigate if key features of HIV viral decay and CD4 trajectories during antiretroviral therapy (ART) are associated with characteristics of HIV viral rebound following ART interruption. Motivated by a real AIDS dataset, two non-linear mixed effects (NLME) models are used to model the viral load trajectories before and following ART interruption, respectively, incorporating left censoring due to lower detection limits of viral load assays. A linear mixed effects (LME) model is used to model CD4 trajectories. The models may be linked through shared random effects, since these random effects reflect individual characteristics of the longitudinal processes. A stochastic approximation EM (SAEM) method is used for parameter estimation and inference. To reduce the computation burden associated with maximizing the joint likelihood, an easy-to-implement three-step (TS) method is proposed by using SAEM algorithm and bootstrap. Data analysis results show that some key features of viral load and CD4 trajectories during ART (e.g., viral decay rate) are significantly associated with important characteristics of viral rebound following ART interruption (e.g., viral set point). Simulation studies are conducted to evaluate the performances of the proposed TS method and the naive method, which still uses SAEM algorithm but substitutes the censored viral load values with half the detection limit and without bootstrap. It is concluded that the proposed TS method outperforms the naive method.
Reform-Oriented Teaching of Introductory Statistics in the Health, Social and Behavioral Sciences-Historical Context and Rationale

description: There is widespread emphasis on reform in the teaching of introductory statistics at the college level. Underpinning this reform is a consensus among educators and practitioners that traditional curricular materials and pedagogical strategies have not been effective in promoting statistical literacy, a competency that is becoming increasingly necessary for effective decision-making and evidence-based practice. This paper explains the historical context of, and rationale for reform-oriented teaching of introductory statistics (at the college level) in the health, social and behavioral sciences (evidence-based disciplines). A firm understanding and appreciation of the basis for change in pedagogical approach is important, in order to facilitate commitment to reform, consensus building on appropriate strategies, and adoption and maintenance of best practices. In essence, reform-oriented pedagogy, in this context, is a function of the interaction among content, pedagogy, technology, and assessment. The challenge is to create an appropriate balance among these domains.

description: We present Swift UV/Optical Telescope (UVOT) imaging of the galaxies M81 and Holmberg IX. We combine UVOT imaging in three near ultraviolet (NUV) filters (uvw2: 1928 Å, uvm2: 2246 Å, and uvw1: 2600 Å) with ground based optical imaging from the Sloan Digital Sky Survey to constrain the stellar populations of both galaxies. Our analysis consists of three different methods. First we use the NUV imaging to identify UV star forming knots and then perform SED modeling on the UV/optical photometry of these sources. Second, we measure surface brightness profiles of the disk of M81 in the NUV and optical. Last we use SED fitting of individual pixels to map the properties of the two galaxies. In agreement with earlier studies we find evidence for a burst in star formation in both galaxies starting ~200 Myr ago coincident with the suggested time of an M81-M82 interaction. In line with theories of its origin as a tidal dwarf we find that the luminosity weighted age of Holmberg IX is a few hundred million years. Both galaxies are best fit by a Milky Way dust extinction law with a prominent 2175 Å bump. In addition, we describe a stacked median filter technique for modeling the diffuse background light within a galaxy, and a Markov chain method for cleaning segment maps generated by SExtractor.

description: We present unambiguous evidence from lattice simulations of QCD with three degenerate quark species for two tricritical points in the (T,m) phase diagram at fixed imaginary μ/T=iπ/3 mod 2π/3, one in the light and one in the heavy mass regime. These represent the boundaries of the chiral and deconfinement critical lines continued to imaginary chemical potential, respectively. It is demonstrated that the shape of the deconfinement critical line for real chemical potentials is dictated by tricritical scaling and implies the weakening of the deconfinement transition with real chemical potential. The generalization to non-degenerate and light quark masses is discussed.

description: Cosmography is a useful tool to constrain cosmological models, in particular dark energy models. In the case of modified theories of gravity, where the equations of motion are generally quite complicated, cosmography can contribute to select realistic models without imposing arbitrary choices a priori. Indeed, its reliability is based on the assumptions that the universe is homogeneous and isotropic on large scale and luminosity distance can be "tracked" by the derivative series of the scale factor a(t). We apply this approach to induced gravity brane-world models where an f(R)-term is present in the brane effective action. The virtue of the model is to self-accelerate the normal and healthy DGP branch once the f(R)-term deviates from the Hilbert-Einstein action. We show that the model, coming from a fundamental theory, is consistent with the LCDM scenario at low redshift. We finally estimate the cosmographic parameters fitting the Union2 Type Ia Supernovae (SNeIa) dataset and the distance priors from Baryon Acoustic Oscillations (BAO) and then provide constraints on the present day values of f(R) and its second and third derivatives.

description: Come in natura un sistema ordinato determina la struttura e la crescita della materia, così anche l’attività umana si è evoluta nel modo di strutturare la società in cui vive, nel modo di organizzarsi e di trasformare l’ambiente in cui abita, prodigandosi nella continua ricerca dell’ordine; il desiderio di portare ordine nella sconcertante confusione delle apparenze riflette un bisogno umano spontaneo e profondo. Per questo motivo, il “Superorganismo” nasce con l’obiettivo di dare ordine, organizzare e valorizzare gli spazi comuni del nuovo campus. Il Superorganismo è un dispositivo di supporto che accoglie tutte le necessità e le esigenze degli spazi che si trovano all’interno dell’edificio. È uno scheletro, una struttura portante che si riveste della vita del campus, mette in mostra e comunica. Per quanto possa sembrare un dispositivo semplice, il Superorganismo racchiude in sé un complicato reticolo che collega non solo la possibilità di costruire e modellare a proprio piacimento uno spazio in maniera flessibile in modo da potersi adattare a diverse situazioni, ma racchiude in sé anche la volontà di diventare elemento di comunicazione e scambio all’interno del campus con lo scopo di mettere in mostra la realtà e la vita delle persone al suo interno. Il Superorganismo diventa così un veicolo per migliorare le relazioni tra persone per conoscere e per farsi conoscere, diventa una vetrina attrattiva e un elemento capace di creare uno spazio dinamico, di generare relazioni e tensioni inedite, dispositivo in continuo movimento. In linea con i principi costruttivi dell’edificio, anche il Superorganismo si impegna a non alterare l’effetto di trasparenza di serialità e di modularità voluti dall’architetto; l’intervento si concretizza così come un telaio strutturale capace di supportare elementi accessori funzionali per dar vita a molteplici situazioni, una struttura estremamente leggera e trasparente, componibile, facile da montare e modulare in modo da poter con facilità modificarne la forma e le dimensioni. Il colore, bianco, è pensato per compensare il rosso dell’edificio, per farsi notare ma nello stesso tempo non prevalere, per inserirsi armoniosamente nel contesto e per adattarsi a ogni genere di elemento che potrebbe essere aggiunto successivamente.
