description: Two bolides (2 June 2016 and 4 April 2019) were detected at multiple regional infrasound stations with many of the locations receiving multiple detections. Analysis of the received signals was used to estimate the yield, location and trajectory, and the type of shock that produced the received signal. The results from the infrasound analysis were compared with ground truth information that was collected through other sensing modalities. This multi-modal framework offers an expanded perspective on the processes governing bolide shock generation and propagation. The majority of signal features showed reasonable agreement between the infrasound-based interpretation and the other observational modalities, though the yield estimate from the 2019 bolide was significantly lower using the infrasound detections. There was also evidence suggesting that one of the detections was from a cylindrical shock that was initially propagating upward, which is unusual though not impossible.

Fossil fuel, capitalism, and the state : a critical approach to the international climate change discourse
Creators: name: Sas, Jonathan
Publisher: name: University of British Columbia
Year: 2010

description: This paper offers a structural critique of the international climate change discourse and challenges the coherency of the norms and logic that underpin the Kyoto Protocol. The first section outlines how the dominant climate discourse in the international community presents the economic imperatives of the state as compatible with the objective of reducing greenhouse gas emissions. The second section argues that in operating to facilitate global economic growth and to sustain the conditions for capital accumulation, the dominant climate discourse in fact precludes states from achieving the emission reductions that are necessary to avert pending and dangerous climactic changes. The argument builds off of the critical treatment of three interconnected facets of the global capitalist system that, it is argued, have caused a metabolic rift to form in the global carbon cycle: (1) the historically specific role of carbon-emitting fossil fuel in the development of capitalism’s constitutive production and circulation processes, what Huber (2009) calls capitalism’s ‘fossil fuel mode of production’; (2) capitalism’s inherent expansionary drive; and (3) the compromised relationship of the state with capital. When combined, these insights suggest that meaningfully reducing greenhouse gas emissions requires the development of a radically different climate discourse, one that fundamentally transforms the structure of the current capitalist system, including, importantly, the imperatives of the modern capitalist state. The paper concludes by offering a sketch of what a postcapitalist state would look like emphasizing the necessary role that it could play to promote strategies of ecological modernisation that foster the development of an alternative energy mode of production. This state would regulate and even proscribe certain destructive tendencies of capital accumulation in order to create economies that cease to threaten the integrity of the global carbon cycle.
The Turnover Dynamics of Residential Buildings
Creators: name: Feiruzi, Aibibula
Publisher: name: Lancaster University
Year: 2024

description: The construction and operation of buildings is one of the most
 resource-intensive elements of the economy, therefore buildings are a
 central focus of efforts to reduce energy use and hence greenhouse gas
 emissions. Because of their long-lasting nature, buildings are also
 important factors in deciding the inertia of economies, and determining
 the turning point of economies in net-zero transitions.

 Traditionally buildings are assigned single representative timescales of
 the order of 80 years. However, building investments may be seen as
 investments in components, each having its own service life ranging from
 seconds to centuries, with returns expected over this interval. The aim of
 this thesis is to explore the relationship between investments in
 buildings and their turnover timescales, which I refer to as the
 investment-timescale distribution, and to identify its role in the capital
 inertia of the building sector in the climate transition.

 In chapter 2, this investment-timescale distribution is first developed
 for a single building using the financial costs of components and their
 expected service life. This is then extended to a representative building
 (RB) by applying a well-established mortality function for the service
 life of each component. The resulting investment-timescale distribution of
 an RB is a near continuous yet multi-modal distribution with a first
 moment of 38 years, remarkably close to the expected working lifetime of
 its inhabitants.

 I explore the implication of this investment-timescale distribution in
 chapter 3, in particular for the dynamic maintenance schedule and economic
 performance of an RB in the UK. This is done by simulating maintenance
 costs to counter the depreciation of components as they approach their
 performance thresholds. I evaluate the performance of this simulation
 using return on investment (ROI). The result is a near stochastic
 maintenance schedule despite the deterministic nature of the simulation.
 This provides a strong indication as to why the interaction of timescale
 spectra with maintenance thresholds yields the complex and hard to predict
 maintenance dynamics we see in real property portfolios.

 Finally, in chapter 4, I apply the investment-timescale dynamics to
 simulate the dynamics of energy demands and carbon liabilities of an RB.
 This simulation contrasts these dynamics under a net-zero carbon policy
 and a business-as-usual (BAU) scenario. The results show that, for new
 build, the longer-lived (>70 years) carbon-intensive components
 avoid much of their maintenance carbon liability if the economy
 decarbonizes in the interim. This also suggests that delaying currently
 carbon intensive construction until less carbon intensive options are
 developed should be considered during the transition to net-zero.
A Possible Fermi liquid in the lightly doped Kitaev spin liquid

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: In this paper, we study the lightly doped Kitaev spin liquid (DKSL) and find it to be a Fermi liquid state. The DKSL has a closed Fermi surface around the center of the Brillouin zone with the quantized volume determined by the Luttinger's theorem. It has well-defined quasiparticles near the Fermi surface and can be detected in the angle-resolved photoemission spectroscopy. The DKSL has the topological Kitaev spin liquid (KSL) as its neutral background. It violates the Wiedemann-Franz law and has a large Wilson ration. These results has the potential experimental test in the iridates upon doping.

description: ASTROD-GW (ASTROD [Astrodynamical Space Test of Relativity using Optical Devices] optimized for Gravitation Wave detection) is an optimization of ASTROD to focus on the goal of detection of gravitation waves. The detection sensitivity is shifted 52 times toward larger wavelength compared to that of LISA. The mission orbits of the 3 spacecraft forming a nearly equilateral triangular array are chosen to be near the Sun-Earth Lagrange points L3, L4 and L5. The 3 spacecraft range interferometrically with one another with arm length about 260 million kilometers. In order to attain the requisite sensitivity for ASTROD-GW, laser frequency noise must be suppressed below the secondary noises such as the optical path noise, acceleration noise etc. For suppressing laser frequency noise, we need to use time delay interferometry (TDI) to match the two different optical paths (times of travel). Since planets and other solar-system bodies perturb the orbits of ASTROD-GW spacecraft and affect the (TDI), we simulate the time delay numerically using CGC 2.7 ephemeris framework. To conform to the ASTROD-GW planning, we work out a set of 20-year optimized mission orbits of ASTROD-GW spacecraft starting at June 21, 2028, and calculate the residual optical path differences in the first and second generation TDI for one-detector case. In our optimized mission orbits for 20 years, changes of arm length are less than 0.0003 AU; the relative Doppler velocities are less than 3m/s. All the second generation TDI for one-detector case satisfies the ASTROD-GW requirement.

Subjects: subject: Educational Psychology
subject: cyber bullying

description: The present study examined the relationship between cyber bullying and psychosocial variables, including parenting styles, and coping strategies. A sample of Canadian students from junior high schools in the Calgary area (N = 125) ages 11 to 15 years (boys= 42, girls = 82, unknown sex = 1) completed online self-report questionnaires on cyber bullying, parenting styles, and coping strategies. To analyze the data, descriptive statistics, t-tests, and analyses of variances of the variables related to parenting styles, coping strategies, and cyber victims were calculated. Results from the quantitative analyses revealed that cyber victims reported significantly lower levels of parental autonomy than their non-cyber victim peers, but did not significantly differ on levels of parental warmth. In terms of coping strategies, cyber victims reported significantly higher levels of avoidance coping strategies than their non-cyber victim peers. In addition, females reported significantly higher levels of parental warmth and avoidance coping strategies than males. Significant, positive correlations between age and parental autonomy were found for both the cyber victim and non-cyber victim groups, but no significant relationships were found between grade and each of the six dependent variables (Warm Involvement, Psychological Autonomy, Active Coping, Distraction Coping, Avoidance Coping, and Support Coping). This study contributes to the understanding of cyber bullying by highlighting the importance of parenting style and the ways children cope with cyber bullying. Empirical and applied implications from this research are suggested and discussed.
WILLINGNESS TO PAY (VONTADE PARA PAGAR) POR UM SERVIÇO DE PREPARAÇÃO INDIVIDUALIZADA DA MEDICAÇÃO (PIM)

description: Introdução: A preparação individualizada da medicação (PIM) é um método útil de gestão da terapêutica em doentes idosos e polimedicados, permitindo maior facilidade na administração do medicamento certo, no dia e hora certos. A utilização deste sistema traduz-se numa maior adesão à terapêutica por parte do doente, com claros benefícios em termos da efetividade e segurança do medicamento, conduzindo consequentemente a uma melhor qualidade de vida.
Objetivos: Determinar a utilidade percecionada sobre um serviço farmacêutico de PIM; avaliar a vontade do doente para receber e pagar (willingness to pay) pelo mesmo.
Métodos: Realizou-se um estudo transversal numa amostra de três farmácias selecionadas intencionalmente (Grande Lisboa e Vale do Tejo e Alentejo), nas quais foram convidados a participar todos os utentes maiores de idade que, durante o período de estudo (um dia em cada farmácia), entrassem na farmácia. A informação foi recolhida através de um questionário composto por cinco perguntas, que se iniciava com uma breve explicação sobre a PIM (verbal e com imagem), sendo seguidamente avaliada a utilidade percecionada do serviço e a sua vontade para pagar pelo mesmo. Os resultados foram tratados em SPSS, versão 19.0, utilizando análise estatística bivariada (testes de t-Student e qui-quadrado) e trabalhando com um intervalo de confiança a 95 por cento. O estudo foi aprovado pela Comissão de Ética do ISCSEM.
Resultados: Foram recolhidos 267 inquéritos, provenientes na sua maioria de utentes do sexo feminino (65,9 por cento); a idade média da amostra foi 56,24 anos (dp=17,824; {19-90}). Dos utentes inquiridos, 58 por cento (n=154) consideraram o serviço útil para si, 71 por cento (n=188) consideraram o serviço útil para outrem e 53,4 por cento (n=142) referiram que estariam disponíveis para pagar pelo serviço caso fosse disponibilizado pela farmácia. Verificou-se que a perceção de utilidade esteve associada ao comportamento considerado aderente, sendo os considerados não aderentes os que percecionaram o serviço como mais útil (p <0,001).Verificou-se ainda que a utilidade percecionada esteve associada à disponibilidade para pagar pelo mesmo (p <0,001).
Conclusão: Este estudo sugere que o sistema DAA pode ser viável em farmácia comunitária, dada a elevada percentagem de utentes que considerou o serviço útil para si ou para outrem. Adicionalmente, verificou--se que uma proporção importante destes utentes se encontra disponível para pagar pelo serviço, embora talvez não o suficiente para cobrir todos os seus custos. Por fim, é importante mencionar que os dados recolhidos não são generalizáveis para outras regiões do país, embora sejam um incentivo para que todos os interessados invistam na prestação de serviços farmacêuticos.

description: Transmission outage scheduling from a transmission facility owner’s (TFO’s) perspective in a de-regulated electricity market is one of the lesser-explored topics in academia. Much of existing literature focuses on generation maintenance scheduling with added transmission constraints from an independent system operator’s point-of-view; however, transmission outage scheduling by itself has not been touched on. This thesis presents a security-constrained transmission outage scheduling model that can be used by any TFO with limited access to system operation information. The proposed mixed-integer linear programming (MILP) model allows multiple outages on a single asset to be scheduled. It also incorporates a new load shedding methodology that allows transmission branches to radially connected and in-and-out connected buses to be taken out-of-service under outage and contingency conditions, which further improves its versatility. The proposed model is tested on two networks, (1) a simple four-bus system and (2) the 62-bus AltaLink 500kV/240kV backbone system in Alberta, Canada.
An Extract of the Tapeworm, Hymenolepis diminuta, Inhibits Neutrophil Migration in vitro

description: Neutrophils are not typically the first cell that comes to mind when the immune response to infection with helminths is considered. However, data are emerging showing that these cells may play an overlooked role in response to helminths perhaps early in the infection and particularly those species that cause tissue damage (e.g. Nippostrongylus brasiliensis - a gut nematode (roundworm)). Additionally, different helminth products have been shown to directly activate neutrophils in vitro (e.g. crude extracts of the porcine cestode Cysticercus cellulosae) and directly induce their chemotaxis (e.g. excretory/secretory products of the sheep nematode Haemonchus contortus). Hymenolepis diminuta crude extract (HdE) has been shown to inhibit dinitrobenzene sulfonic acid-induced colitis. Intraperitoneal injection of this crude extract recruited a population of peritoneal exudate cells dominated by neutrophils at 4h post-injection. Remarkably, these neutrophil-predominant PECs evoked increased production of the anti-inflammatory cytokine IL-10 from co-cultures of activated murine splenic CD4+ T cells. HdE did not directly induce murine neutrophil chemotaxis in vitro and direct application of HdE to neutrophils was not preferentially cytotoxic as assessed by trypan blue staining and LDH release. HdE did however induce Ca2+ mobilization and respiratory burst by murine neutrophils in vitro. In contrast to its ability to recruit neutrophils to the peritoneal cavity, HdE inhibited neutrophil chemotaxis in response to WKYMVm and keratinocyte derived chemokine (KC). HdE was unable to modulate neutrophil migration towards leukotriene B4. Biochemical characterizations (boiling, trypsinization, acidification, and sodium metaperiodate treatment) suggested that an acid-stable glycoprotein was responsible for its ability to block migration towards WKYMVm. The ability of HdE to block migration towards WKYMVm appears to be independent of the phosphorylation of the mitogen-activated protein kinase, p38. HdE did not directly induce production of the cytokines, IL-10, TNF-α, and KC. It also did not modulate production of these cytokines induced by other activators. In conclusion: (1) HdE activated neutrophils to mobilize Ca2+ into the cytoplasm and produce ROS; and, (2) an acid-stable glycoprotein component of the HdE inhibited neutrophil migration towards WKYMVm.

description: Introduction: Elderly population is frequently polymedicated, including with potentially inappropriate medications (PIM), sometimes instead of preventive medication, designated as potentially prescribing omissions (POM).
Objectives: This study aims to characterize and to quantify the occurrence of PIM and POM in a sample of institutionalized elderly patients through a medication review using STOPP (Screening Tool of Older Person’s Prescriptions) and START (Screening Tool to Alert doctors to Right Treatment) criteria.
Methods: A descriptive cross-sectional study was used, where 4 elderly facilities were invited to participate. Patients aged ≥65 and using ≥5 medicines were included in the study and their medication was analyzed using STOPP and START criteria. Data were analyzed using univariate and bivariate descriptive statistics (Mann-Whitney U and Kruskal-Wallis tests), considering a significance level of 95%.
Results: The final sample included 126 individuals, with a mean age of 84.81 years (SD=6.126), 69.0% being female. A total of 1315 medicines were analyzed, and 214 PIM (16.27%) and 90 POM (6.84%) were identified through the application of the STOPP and START criteria, respectively. Data indicates that 75.4% of the sample had one or more PIM (M=1.71 /patient; SD=1,470) and 42.9% had one or more POM (M=0.72/patient; SD=1,048).
Conclusion: The application of the STOPP and START criteria enabled the identification of a considerable amount of PIM and POM, indicating them as tools that contribute to review and change, if necessary, the instituted therapy in elderly. The development of pharmaceutical competencies in the care of geriatric patients, even though not evaluated in the current study, may constitute the basis for future opportunities for pharmaceutical intervention and valuing of the pharmacist’s role.

description: Let $S$ be a set of $n$ points in $d$-dimensional Euclidean space. Assign to each $x\in S$ an arbitrary distance $r(x)>0$. Let $e_r(x,S)$ denote the number of points in $S$ at distance $r(x)$ from $x$. Avis, Erdös and Pach (1988) introduced the extremal quantity $f_d(n)=\max\sum_{x\in S}e_r(x,S)$, where the maximum is taken over all $n$-point sets $S$ in $d$-dimensional space and all assignments $r\colon S\to(0,\infty)$ of distances. We give a quick derivation of the asymptotics of the error term of $f_d(n)$ using only the analogous asymptotics of the maximum number of unit distance pairs in a set of $n$ points, which improves on previous results of Avis, Erdös and Pach (1988) and Erdös and Pach (1990). Then we prove a stability result for $d\geq 4$, asserting that if $(S,r)$ with $|S|=n$ satisfies $e_r(S)=f_d(n)-o(n^2)$, then, up to $o(n)$ points, $S$ is a Lenz construction with $r$ constant. Finally we use stability to show that for $n$ sufficiently large (depending on $d$) the pairs $(S,r)$ that attain $f_d(n)$ are up to scaling exactly the Lenz constructions that maximise the number of unit distance pairs with $r\equiv 1$, with some exceptions in dimension 4. Analogous results hold for the furthest neighbour digraph, where $r$ is fixed to be $r(x)=\max_{y\in S} |xy|$ for $x\in S$.

description: We present a novel framework for integrating prior knowledge into discriminative classifiers. Our framework allows discriminative classifiers such as Support Vector Machines (SVMs) to utilize prior knowledge specified in the generative setting. The dual objective of fitting the data and respecting prior knowledge is formulated as a bilevel program, which is solved (approximately) via iterative application of second-order cone programming. To test our approach, we consider the problem of using WordNet (a semantic database of English language) to improve low-sample classification accuracy of newsgroup categorization. WordNet is viewed as an approximate, but readily available source of background knowledge, and our framework is capable of utilizing it in a flexible way.

description: Energy systems are under pressure to transform to address concerns about climate change. The modeling and visualization of energy systems can play an important role in communicating the costs, benefits and tradeoffs of energy systems choices. In this thesis, we introduce a visualization system that provides an interface for exploring time-varying, multi-attribute and spatial properties of a particular energy system. This system integrates several visualization techniques to facilitate exploration of a particular energy system. These techniques include flow diagram representation to show energy flow, 3D interaction with flow diagrams for expanding viewable data attributes such as emissions and an interactive map integrated with flow diagrams for simultaneous exploration of spatial and abstract information. We also perform level of detail exploration on flow diagrams and use smooth animation across the visualizations to represent time-varying data. We finally, include evaluation results of our system collected from expert and inexperienced participants. These results reflect on overall effectiveness of our visualization system and the novel features we developed.

description: The spin-1 Heisenberg model on a triangular lattice with the ferromagnetic nearest, $J_1=-(1-p)J,$ $J>0$, and antiferromagnetic third-nearest-neighbor, $J_3=pJ$, exchange interactions is studied in the range of the parameter $0 \leqslant p \leqslant 1$. Mori's projection operator technique is used as a method, which retains the rotation symmetry of spin components and does not anticipate any magnetic ordering. For zero temperature several phase transitions are observed. At $p\approx 0.2$ the ground state is transformed from the ferromagnetic spin structure into a disordered state, which in its turn is changed to an antiferromagnetic long-range ordered state with the incommensurate ordering vector ${\bf Q = Q^\prime} \approx (1.16, 0)$ at $p\approx 0.31$. With the further growth of $p$ the ordering vector moves along the line ${\bf Q^\prime-Q_c}$ to the commensurate point ${\bf Q_c}=(\frac{2π}{3}, 0)$, which is reached at $p = 1$. The final state with an antiferromagnetic long-range order can be conceived as four interpenetrating sublattices with the $120^\circ$ spin structure on each of them. Obtained results are used for interpretation of the incommensurate magnetic ordering observed in NiGa$_2$S$_4$.

description: Prostate specific antigen (PSA) testing for the screening of prostate cancer is controversial with medical and governmental organizations issuing contradictory statements regarding its use. My research looked at the utilization of the PSA test for the screening of prostate cancer in Calgary, Alberta for 2011 and if sociodemographic factors influenced the rate of testing. I studied whether PSA velocity is better than a single PSA test in predicting prostate biopsy outcome and if sub-dividing Gleason score 7 prostate cancers improves the predictive ability of PSA tests. My research found that PSA testing does not follow official guidelines in younger men and that certain sociodemographic factors do influence the rate of PSA testing. I found that PSA velocity is not better than the PSA test in predicting prostate biopsy diagnosis and that sub-dividing Gleason score 7 prostate cancers can increase the clinical utility of the PSA test.

description: Several lines of evidence, from isotopic analyses of meteorites to studies of the Sun's elemental and isotopic composition, indicate that the solar system was contaminated early in its evolution by ejecta from a nearby supernova (SN). Previous models have invoked SN material being injected into an extant protoplanetary disk, or isotropically expanding ejecta sweeping over a distant (>10 pc) cloud core, simultaneously enriching it and triggering its collapse. Here we consider a new astrophysical setting: the injection of clumpy SN ejecta, as observed in the Cas A SN remnant, into the molecular gas at the periphery of an HII region created by the SN's progenitor star. To track these interactions we have conducted a suite of high-resolution (1500^3 effective) 3D simulations that follow the evolution of individual clumps as they move into molecular gas. Even at these high resolutions, our simulations do not quite achieve numerical convergence, due to the challenge of properly resolving the small-scale mixing of ejecta and molecular gas, although they do allow some robust conclusions to be drawn. Isotropically exploding ejecta do not penetrate into the molecular cloud, but, if cooling is properly accounted for, clumpy ejecta penetrate to distances ~10^18 cm and mix effectively with star-forming molecular gas. The ~2 M_\odot high-metallicity ejecta from a core-collapse SN is likely to mix with ~2 \times 10^4 M_\odot of molecular gas. Thus all stars forming late (~5 Myr) in the evolution of an HII region may be contaminated by SN ejecta at a level ~10^-4. This level of contamination is consistent with the abundances of short-lived radionuclides and possibly some stable isotopic shifts in the early solar system, and is potentially consistent with the observed variability in stellar elemental abundances. SN contamination of forming planetary systems may be a common, universal process.

This approach --discarding hydrodynamics interactions-- first allows us to improve the efficiency of previous Dynamic Monte Carlo algorithms for spherical Brownian particles. In a second step, we address the case of anisotropic colloids with orientational degrees of freedom. As an illustration, we present a detailed study of the dynamics of thin platelets, with emphasis on long-time diffusion and orientational correlations.

description: The emergence of fluorescent reporters has enabled neuroscientists to image neurons in action in live mice. Conventional imaging setups, however, cannot interrogate structures below the surface of the brain, and the animal must be restrained. This work advances fiber photometry, a simple method to monitor the average activity of a population of cells, to enable experiments in freely-moving mice and in deep brain structures. By targeting a small-diameter probe to the structure of interest, single fiber optoelectronic systems may be designed that monitor changes in calcium-mediated fluorescence intensity. The systems are optimized for an application in a CRH-Cre transgenic mouse, with the calcium reporter GCaMP6s, for minimal damage to tissue. This thesis covers: (a) optoelectronic system design, characterization, and refinement (b) application and results in awake and freely-moving mice, (c) investigation into potential artifacts and (d) method and results of an improved targeting protocol.
Note About Equivalence of F(R) and Scalar Tensor Horava-Lifshitz Gravities

description: In this note we study the relation between F(R) and scalar tensor Horava-Lifshitz gravity. We find that due to the broken diffeomorphism invariance corresponding scalar tensor theory has more complicated form than in case of the full diffeomorphism invariant F(R) theory of gravity. We also show that in the low energy limit this theory flows to the relativistic scalar tensor theory of gravity.

description: Biosimilar medicinal products have become a reality in recent years. Despite an established legal pathway for biosimilars in the European Union since 2005 and increasing regulatory guidance on data requirements for their development and approval, many clinicians are still reluctant to consider biosimilars as a treatment option for their patients. Moreover, the approval of biosimilars has prompted the discussion of whether these products can be safely switched with the innovator biopharmaceuticals without a negative impact on the efficacy of the treatment or an increased risk of immunogenicity. This review gives an overview of the available data related to the switch between an originator product and a biosimilar. A search was conducted for pre- and post-approval clinical studies involving patients that were switched between innovator drugs and EMA approved biosimilars. Currently, there is limited clinical data that specifically investigates the effects of switching. Nevertheless, the data analyzed from clinical studies reporting on switching between originator products and their respective biosimilars indicates that switching has no impact on the efficacy, safety and immunogenicity of treatment in patients.

description: We consider the exterior Cauchy-Dirichlet problem for equivariant wave maps from 3+1 dimensional Minkowski spacetime into the three-sphere. Using mixed analytical and numerical methods we show that, for a given topological degree of the map, all solutions starting from smooth finite energy initial data converge to the unique static solution (harmonic map). The asymptotics of this relaxation process is described in detail. We hope that our model will provide an attractive mathematical setting for gaining insight into dissipation-by-dispersion phenomena, in particular the soliton resolution conjecture.

Properties of empirical and adjusted empirical likelihoods
Creators: name: Huang, Yi
Publisher: name: University of British Columbia

description: Likelihood based statistical inferences have been advocated by generations of statisticians. As an alternative to the traditional parametric likelihood, empirical likelihood (EL) is appealing for its nonparametric setting and desirable asymptotic properties. In this thesis, we first review and investigate the asymptotic and finite-sample properties of the empirical likelihood, particularly its implication to constructing confidence regions for population mean. We then study the properties of the adjusted empirical likelihood (AEL) proposed by Chen et al. (2008). The adjusted empirical likelihood was introduced to overcome the shortcomings of the empirical likelihood when it is applied to statistical models specified through general estimating equations. The adjusted empirical likelihood preserves the first order asymptotic properties of the empirical likelihood and its numerical problem is substantially simplified. A major application of the empirical likelihood or adjusted empirical likelihood is the construction of confidence regions for the population mean. In addition, we discover that adjusted empirical likelihood, like empirical likelihood, has an important monotonicity property. One major discovery of this thesis is that the adjusted empirical likelihood ratio statistic is always smaller than the empirical likelihood ratio statistic. It implies that the AEL-based confidence regions always contain the corresponding EL-based confidence regions and hence have higher coverage probability. This result has been observed in many empirical studies, and we prove it rigorously. We also find that the original adjusted empirical likelihood as specified by Chen et al. (2008) has a bounded likelihood ratio statistic. This may result in confidence regions of infinite size, particularly when the sample size is small. We further investigate approaches to modify the adjusted empirical likelihood so that the resulting confidence regions of population mean are always bounded.

description: Tumours arise by mutation and natural selection among cellular lineages. Understanding and modelling mutation is thus a central aspect of cancer research. Genes that confer a selective advantage to their cell-line when mutated are known as drivers and are usually identified by statistical enrichment of mutations. Current approaches to detect drivers make several simplifying assumptions, sacrificing biological realism for computational speed when modelling mutation. The main novel, technical contribution of this thesis is the presentation of a principled mathematical framework for mutational analysis in genomic data that we term ``Mut-HMM''. Calculations required for large-scale inference were parallelized to take advantage of many-core CPU clusters. Based on this work, I present a new software package that can be orders of magnitude faster than previous state-of-the-art methods for analysis of genome-wide mutation patterns. I then present an exploratory analysis of chromosome 22 germline mutation data, showing that the results highlight the need for more complex and sophisticated mutation models in cancer and human genomics.

description: Slides and attached script for a presentation delivered to the Te Papa natural history team explaining how to use ORCID, Wikidata and Bionomia to link both living and deceased Te Papa natural history collectors and determiners to their specimens. It explains how this linking, the creation of Bionomia profiles for Te Papa staff, and the integration of those Bionomia profiles with Zenodo, can be used by Te Papa staff to help obtain professional credit for their work. It also explains how these workflows can be used to enrich Te Papa’s person data more generally, ensuring it can be improved prior and subsequent to export into GBIF. This presentation also outlines how this improvement will prepare Te Papa’s person data for use in digital extended specimens.
Performance of tau-lepton reconstruction and identification in CMS

description: The performance of tau-lepton reconstruction and identification algorithms is studied using a data sample of proton-proton collisions at sqrt(s)=7 TeV, corresponding to an integrated luminosity of 36 inverse picobarns collected with the CMS detector at the LHC. The tau leptons that decay into one or three charged hadrons, zero or more short-lived neutral hadrons, and a neutrino are identified using final-state particles reconstructed in the CMS tracker and electromagnetic calorimeter. The reconstruction efficiency of the algorithms is measured using tau leptons produced in Z-boson decays. The tau-lepton misidentification rates for jets and electrons are determined.

description: Maria Montessori based her educational approach on a profound understanding of the spiritual nature of the child, on the spiritual preparation of the teacher, and on the teacher-child relationship. However, she did not elaborate on the nature of teacher teams, nor on the spiritual aspect of teamwork. Though most Montessori early childhood classrooms have two or more teachers who teach together as a team, very little research has been conducted on how these teams work together, nor on how spirituality influences their work. The purpose of this research was to examine the role that spirituality played in the perceptions and understandings that Montessori teachers brought to their interactions in classroom teams. The methodology taken was a basic interpretive study. The purposeful sample consisted of five Montessori early childhood teachers teaching on three different teams of three teachers, in the same Montessori school in Western Canada. The data collection method included a short questionnaire, an observation of the teacher in the classroom with her team, her selection of an artifact representing spirituality and teamwork, two semi-structured interviews, and a member check. The analysis and interpretation of the findings were organized according to three categories arising from the data and from the theoretical framework: 1) the relationship that the teacher had with her spiritual self, 2) the teacher-child relationship, and 3) the teacher-teacher relationship. This study revealed that the spiritual self of the teacher was important in the development of the teacher-child relationship, and with the team. The Montessori concept of the inner teacher was examined in light of these findings. All the participants stated that spirituality played a role in their team interactions, and that there was congruence between how they related with the children and with each other. Peace was the overriding goal of the teachers for the classroom and with each other. Moreover, love for the child undergirded everything that they did. Recommendations are offered for Montessori teams, and teams in other areas of work, as well as future research in this area.
