description: Understanding causal relations is vital in scientific discovery. The process of causal structure learning involves identifying causal graphs from observational data to understand such relations. Usually, a central server performs this task, but sharing data with the server poses privacy risks. Federated learning can solve this problem, but existing solutions for federated causal structure learning make unrealistic assumptions about data and lack convergence guarantees. FedC2SL is a federated constraint-based causal structure learning scheme that learns causal graphs using a federated conditional independence test, which examines conditional independence between two variables under a condition set without collecting raw data from clients. FedC2SL requires weaker and more realistic assumptions about data and offers stronger resistance to data variability among clients. FedPC and FedFCI are the two variants of FedC2SL for causal structure learning in causal sufficiency and causal insufficiency, respectively. The study evaluates FedC2SL using both synthetic datasets and real-world data against existing solutions and finds it demonstrates encouraging performance and strong resilience to data heterogeneity among clients.

description: A systematic study of the indoor airborne radon concentration in the central part of the Nicosia district was conducted, using high-sensitivity active radon portable detectors of the type "RADIM3A". From a total of 108 measurements in 54 grids of 1 km^2 area each, the overall mean value is 20.6 \pm 13.2 Bq m^-3 (A.M.\pm S.D.). That is almost twice less than the corresponding average worldwide value. The radon concentration levels in drinking water were also measured in 24 sites of the residential district, using the high-sensitivity radon detector of the type "RADIM3W". The mean value obtained from these measurements is 243.8 \pm 224.8 mBq L^-1, which is relatively low compared to the corresponding internationally accepted level. The associated annual effective dose rates to each measurement were also calculated and compared to the corresponding worldwide values. From the geographical coordinates of the measuring sites and the corresponding radon concentration values, the digital radon map of the central part of the Nicosia district was constructed for the first time, by means of the ArcMap software package.

description: Policy and technological factors outside the immediate boundaries of environmental resource areas are increasingly viewed as critical to the outcomes of chosen management strategies. In particular, the derivation of commons policy by most developing countries from a similar set of international treaties and processes often results in uncertain and unintended consequences on local development. I undertook a multi-scalar policy analysis case study with a mixed methods approach of Kenya forestry governance by examining how external factors influence national policies and selected local community development projects in order to contribute to theory and programmatic improvements. Political ecology was adopted as the broad investigative tool toward multiple socially constructed realities for different actors. Study participants were located at local, national and international agency levels with a focus on international treaties and processes impacting on forest governance. I found that international actors had, in practice, acquired significant stake-holding of contested forest areas in Kenya through their categorization as globally significant biodiversity habitats. The emergence of horizontal and vertical networks and coalitions propagated skewed power relationships in the new multilevel management arrangements. Normative goals of international environmental treaties aimed at benefitting local communities were routinely superseded by higher level interests with preference for the maintenance of the status quo such as neoliberal-informed and centralized commons management. I recognized the centrality of a shared commons in the rural development agenda and the need to adopt more redistributive contextualized policies and intervention programs that give relevance to accepted and relevant local cultural practices if more sustainable outcomes are to be achieved. More collaborative efforts and linkages at vertical and horizontal levels within and between Community Forest Associations, development cooperatives at regional and national levels, and deliberate linkages to international nongovernmental organizations that support their beliefs in practice will be critical in reversing the power imbalances observed in forest governance. Because ICDPs have evolved into major development mechanisms in Kenya’s overall development process I recommended that a comprehensive and inclusive political definition of its boundaries and aims should be undertaken in order to rationalize its operations within the overall development agenda.
Three Essays in Structural Estimation: Models of Matching and Asymmetric Information
Creators: name: Chen, Liang
Publisher: name: Arts
Year: 2014
Subjects: subject: Economics--Finance
subject: Structural Estimation

description: There is growing interest in using structural estimation methods to address economic questions. There are two main two advantages of using structural estimation methods. First, they can solve the endogeneity problem confronting numerous reduced-form regression works. Second, they estimate the deep parameters of the models, which allows researchers to analyze many interesting economic questions through counterfactual analysis. In this dissertation, I study three di erent economic questions by structurally estimating models of matching and asymmetric information. In the rst chapter, I develop an estimable model which illustrates that the presence of moral hazard not only leads to ine ciency caused by risk sharing across rms and CEOs, but also creates ine ciency due to a talent misallocation. A new empirical method is proposed to identify the separate surplus of both rms and CEOs in a matching market with moral hazard. An application of this method to the U.S market for CEOs shows that the aggregate e ciency loss due to talent misallocation is $12:64 billion. This is more than four times as large as the loss stemming from risk-sharing between rms and CEOs. In the second chapter, my coauthor and I propose a new approach to identify models with network e ects by invoking another side of the market. We show that other side of the market provides additional information for identi cation. Our running application investigates the importance of asymmetric information and network e ects in the yellow pages advertising industry. In the third chapter, I study estimation and non-parametric identi cation of a dynamic matching model with a broader class of generalized unobserved heterogeneities. I rst provide the identi cation results on the match surplus. I then show that the match equilibrium exists and is globally unique. Finally, I provide a new estimation method for our dynamic matching model, which provides more precise estimates than previous methods.

description: This white paper, submitted to the Heliophysics 2050 Workshop, emphasizes the need for specific types of near-real-time observations that can improve nowcasting of Solar Energetic Particle (SEP) events. The paper demonstrates the benefits of near-real-time measurements of: 1) CME acceleration in the very low corona; 2) 0.04 to 0.5 nm X-Rays; 3) low frequency radio emissions; and 4) relativistic electron intensities to SEP forecasts and provides recommendations for the availability of these observations to support astronaut flights to the Moon and Mars in the 2020s and 2030s.

description: Smartphones with large screens provide users with increased display and interaction space but pose challenges in reaching certain areas with the thumb when using the device with one hand. To address this, we introduce GazeSwipe, a multimodal interaction technique that combines eye gaze with finger-swipe gestures, enabling intuitive and low-friction reach on mobile touchscreens. Specifically, we design a gaze estimation method that eliminates the need for explicit gaze calibration. Our approach also avoids the use of additional eye-tracking hardware by leveraging the smartphone's built-in front-facing camera. Considering the potential decrease in gaze accuracy without dedicated eye trackers, we use finger-swipe gestures to compensate for any inaccuracies in gaze estimation. Additionally, we introduce a user-unaware auto-calibration method that improves gaze accuracy during interaction. Through extensive experiments on smartphones and tablets, we compare our technique with various methods for touchscreen reachability and evaluate the performance of our auto-calibration strategy. The results demonstrate that our method achieves high success rates and is preferred by users. The findings also validate the effectiveness of the auto-calibration strategy.

description: Glitches, spin-up events in neutron stars, are of prime interest as they reveal properties of nuclear matter at subnuclear densities. We numerically investigate the glitch mechanism due to vortex unpinning using analogies between neutron stars and dipolar supersolids. We explore the vortex and crystal dynamics during a glitch and its dependence on the supersolid quality, providing a tool to study glitches from different radial depths of a neutron star. Benchmarking our theory against neutron star observations, our work will open a new avenue for the quantum simulation of stellar objects from Earth.

description: Health literacy has become a relatively popular notion in the past 15 years in both the policy and professional-practices realms in Canada and abroad. While health literacy has emerged from public health, health education, and health promotion, historically, its increasing presence in discourses surrounding clinical and public health practices has focused on defining, measuring, and operationalising notions of health literacy, rather than attempting to understand what health literacy means to and has to offer the actual individuals implicated in its practice. In seeking to understand health literacy more deeply, a critical literature review has been undertaken; from this point, in pursuit of a greater appreciation of the overlapping and intersecting notions in the field of health literacy, an auto/ethnographic account of the concept from the perspective of a new mother and a new chronic illness and injury patient has been constructed. What has resulted is a classically composed, but narratively varied, examination of these impressions and experiences. Ultimately, no common account of health literacy has emerged: rather, what has been found is more closely akin to a ‘family resemblance’, one that presents challenges, and perhaps opportunities, to expand the discussions clinically and publically about this notion that, finally, affects us all.

description: Sensor-based degradation signals measure the accumulation of damage of an engineering system using sensor technology. Degradation signals can be used to estimate, for example, the distribution of the remaining life of partially degraded systems and/or their components. In this paper we present a nonparametric degradation modeling framework for making inference on the evolution of degradation signals that are observed sparsely or over short intervals of times. Furthermore, an empirical Bayes approach is used to update the stochastic parameters of the degradation model in real-time using training degradation signals for online monitoring of components operating in the field. The primary application of this Bayesian framework is updating the residual lifetime up to a degradation threshold of partially degraded components. We validate our degradation modeling approach using a real-world crack growth data set as well as a case study of simulated degradation signals.

Cultural variations in mothers' acceptability of behavioral child management techniques : examination of underlying mechanisms
Creators: name: Mah, Janet W.T.
Publisher: name: University of British Columbia
Year: 2010

description: Behavioral parent training (BPT) is a widely used, evidence-based treatment and prevention intervention for managing noncompliant and disruptive child behavior. However, the cultural sensitivity of the techniques emphasized within the program has been largely unexamined. This study examined cultural differences in mothers’ acceptance of common techniques for managing disruptive child behavior, and the possible roles of parenting styles and implicit theories in mediating any cultural differences. A community sample of 117 Euro-Canadian and Chinese-immigrant mothers of boys aged 4- to 8-years participated. Results indicated that Chinese-immigrant mothers had more favorable attitudes towards punishment techniques (i.e., over-correction and spanking) than Euro-Canadian mothers, and that mothers’ authoritarian and training parenting styles were mediators underlying this cultural difference. No cultural differences were found in mothers’ attitudes towards reward (i.e., praise and token economy) or withdrawal of positive reinforcement (i.e., response cost and time-out) techniques. This study takes a first step to inform efforts to increase cultural sensitivity in approaches to the delivery of mental health services to the underserved population of Chinese-immigrant families.
Lepton flavor violation in minimal flavor violation extensions of the seesaw

Publisher: name: arXiv
Year: 2011
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: A minimal flavour violation hypothesis for leptons can be implemented essentially in two ways that are compatible with a type-I seesaw structure with three heavy singlet neutrinos $N$, and that satisfy the requirement of being predictive, in the sense that all lepton flavor violating (LFV) effects can be expressed in terms of low energy observables. The first realization is CP conserving and is based on the flavor group $SU(3)_e\times SU(3)_\ell\times O(3)_N$ (being $e$ and $\ell$ the SU(2) singlet and doublet leptons). The second realization allows for CP violation and is based on $SU(3)_e\times SU(3)_{\ell+N}$. I review the main features of the two schemes and point out their different implications for LFV observables.

description: These are the lecture notes for an introductory course on black holes and some aspects of their interaction with the classical and quantum world. The focus is on phenomena of "fundamental physics" in the immediate surroundings of the black hole (classical and quantum fields, with little astrophysics). We aim more at qualitative, intuitive understanding than at quantitative rigor or detail. Accordingly, we only assume previous exposure to a conventional introduction to the elements of General Relativity and a glancing acquaintance with the Schwarzschild solution, but not more. We use many figures for illustrations and provide a set of carefully guided exercises. Topics: (1) The black hole as a tale of light and darkness. (2) The black hole that vibrates. (3) The black hole that rotates. (4) The black hole that evaporates. (A) Guided problems.

Subjects: subject: Education--Art
subject: Art Education

description: This case study describes the impact an artist can have on school culture when they set up their studio space within a public school. The artists were given the freedom to engage in their artistic pursuits without predetermined teaching requirements or a prescribed role within the school. This unique opportunity for artists and school populations arose from collaboration between an art college and a public school board. This thesis will describe the experiences from the perspectives of the artists, school administrators, teachers and students. The results indicate how authentic encounters with art and artists influence the learning in schools. Studio artists who modeled and shared their artistic dispositions and expertise impacted the school’s environment, relationships, student agency and contributed to meaningful work. The data shares the potential and possibilities that exist when a studio artist is invited to share their art and practice in a school.

In this paper we study the $h$-polynomial of $K[\mathcal{P}]$ in terms of the switching rook polynomial of $\mathcal{P}$ using the shellable simplicial complex $Δ(\mathcal{P})$ attached to $\mathcal{P}$. We provide a suitable shelling order for $Δ(\mathcal{P})$ and we define a bijection between the set of the canonical configurations of $j$ rooks in $\mathcal{P}$ and the facets of $Δ(\mathcal{P})$ with $j$ steps. Finally we use a well-known combinatorial result, due to McMullen and Walkup, about the $h$-vector of a shellable simplicial complex to interpret the $h$-polynomial of $K[\mathcal{P}]$ as the switching rook polynomial of $\mathcal{P}$.

description: We construct Seiberg-Witten curves for 5d $\mathcal{N}=1$ gauge theories whose Type IIB 5-brane configuration involves an O7-plane and discuss an intriguing relation between theories with an O7$^+$-plane and those with an O7$^-$-plane and 8 D7-branes. We claim that 5-brane configurations with an O7$^+$-plane can be effectively understood as 5-brane configurations with a set of an O7$^-$-plane and eight D7-branes with some special tuning of their masses such that the D7-branes are frozen at the O7$^-$-plane. We check this equivalence between SU($N$) gauge theory with a symmetric hypermultiplet and SU($N$) gauge theory with an antisymmetric with 8 fundamentals, and also between SO($2N$) gauge theory and Sp($N$) gauge theory with eight fundamentals. We also compute the Seiberg-Witten curves for non-Lagrangian theories with a symmetric hypermultiplet, which includes the local $\mathbb{P}^2$ theory with an adjoint.

description: The observation of neutrinoless double-beta decay would resolve the Majorana nature of the neutrino and could provide information on the absolute scale of the neutrino mass. The initial phase of the Majorana experiment, known as the Demonstrator, will house 40 kg of Ge in an ultra-low background shielded environment at the 4850' level of the Sanford Underground Laboratory in Lead, SD. The objective of the Demonstrator is to determine whether a future 1-tonne experiment can achieve a background goal of one count per tonne-year in a narrow region of interest around the 76Ge neutrinoless double-beta decay peak.

description: Observing the early years of the 1920's, it is possible to detect a fracture in the perception of relativity theory in Argentina, characterized by the publication of a series of strictly scientific studies on this theory, in parallel with presentations aimed at the general culture. In this work, we attempt to relate this fracture with the advances made by Anti-Positivist ideas in the higher echelons of Argentine culture. The new philosophical approach configured a new vision of science that questioned the traditional methodology of the experimental sciences and attributed to the theoretical sciences a more prominent role than they had in the past. In this work, we present a detailed account of a 1923 paper by José B. Collo and Teófilo Isnardi, two young Argentine physicists trained in Germany, which is a representative contribution to this new trend.

description: Guided by an ecological framework, this study has made an attempt to gain a thorough understanding of how Chinese immigrant parents think of and arrange their children’s out-of-school time (OST) activities in the context of their perceptive and experiential world before and after immigration. Based on the rich and thoughtful data I sought through interviews with my 12 respondents, this study revealed an interactive dynamic of operations at different levels. Namely, my findings have suggested from in-depth to surface at least three interrelated levels of operations: the process of multiple stages that these parents have gone through resulted in the movements and shifts in their mind and life; the exemplified influence on childrearing from in-depth level on OST associated understanding, choice of patterns, and multi-functions of OST activities; and subsequently, the required premises and conditions for OST participation on the surface level. An obvious gap was detected between parents’ understanding of competencies in the Canadian context and their actual choice of out-of-school time activities for children. Eventually, all the effort these immigrant parents made direct to the ultimate goal of creating an enjoyable, fulfilled, and “normal life” for their children and preparing them for their future in the adult world, which is essentially a part of their adaptation task in the Canadian context. I suggest that how parents make what decisions with regard to their children’s OST participation cannot be understood in an isolated way without looking at the sources of constant influences coming from broader and deeper ecological systems.

subject: oil sands

description: The McMurray Formation of the Athabasca Oil Sands hosts one of the largest hydrocarbon resources on Earth, yet the provenance of the sediment itself remains poorly constrained. As the first detrital zircon provenance study from the oil sands, new uranium-lead (U-Pb) detrital zircon ages provide important insights into Early Cretaceous paleogeography, continental-scale sediment transport, and assist in the correlation of incised valley deposits. 27 samples dated using laser ablation–multicollector–inductively coupled plasma–mass spectrometry (LA-MC-ICP-MS) reveal two sets of three distinct detrital-zircon signatures. Each set is documented and grouped into three chronofacies, interpreted to reflect derivation from the Canadian Shield, the Appalachians, and the Cordilleran orogen. Several hypotheses are presented to answer the question of when and how sediments from eastern North America were transported to western Canada. These data are combined with subsurface correlations and chemostratigraphic data to demonstrate the complexity of valley fills and examine the relationship between different valley deposits.

description: We study general classes and properties of extremal and non-extremal static black-hole solutions of N=2, d=5 supergravity coupled to vector multiplets using the recently proposed H-FGK formalism, which we also extend to static black strings. We explain how to determine the integration constants and physical parameters of the black-hole and black-string solutions. We derive some model-independent statements, including the transformation of non-extremal flow equations to the form of those for the extremal flow. We apply our methods to the construction of example solutions (among others a new extremal string solution of heterotic string theory on K_3 \times S^1). In the cases where we have calculated it explicitly, the product of areas of the inner and outer horizon of a non-extremal solution coincides with the square of the moduli-independent area of the horizon of the extremal solution with the same charges.

description: Congenital heart defects are the most common birth defect and affect ~1/100 newborns. While our knowledge of the underlying developmental mechanisms of the heart has greatly expanded in recent years, there are still many idiopathic conditions that must be explored. Conserved developmental mechanisms have made the fruit fly, Drosophila melanogaster, instrumental to our current understanding heart development. The T-box transcription factor midline (mid) and its vertebrate homologue, Tbx20, have demonstrated roles in the developing heart. This thesis explores the function of mid in the developing heart. To identify genes regulated by mid, I performed gene expression profiling on embryos ectopically expressing mid. This approach identified 565 genes at 1.5-fold p<0.05 that respond to ectopic mid. To identify potential direct targets of mid, I identified a DNA motif recognized by Mid (CAAGGTGTCAAGGCG). Searching the gene-span +/- 2 kb of each D. melanogaster gene identified 2112 potential Mid targets. Of these, 86 were in common with hits from expression profiling. An RNAi screen of genes most strongly affected by ectopic mid found that knockdown of CG32373, closely related to cell-surface or secreted proteins, led to an observable phenotype in the heart. However, CG32373 in situ hybridization appears limited to the trachea and does not appear induced in mid mutants, despite reductions in its transcripts in response ectopic mid detected by qPCR. Furthermore, only one of two CG32373 RNAi lines was able to induce a phenotype. To identify mechanisms that Mid uses to regulate its targets, I examined the expression of known and novel targets in embryos ectopically expressing mid alleles with mutations in conserved domains. None of the three domains strongly affected the rescue of tin or svp. However, the response of some genes identified through expression profiling was altered when mutant alleles of mid were expressed. The results contained in this thesis further our understanding of mid function and more importantly, our understanding of heart development. Further exploration of the identified genes in both flies and humans will likely expand the potential targets for treatment and diagnosis of congenital heart defects.

description: Chemical erosion, one of the two major erosion processes along with mechanical erosion, occurs when a soluble rock like salt, gypsum or limestone is dissolved in contact with a water flow. The coupling between the geometry of the rocks, the mass-transfer and the flow leads to the formation of remarkable patterns, like scallop patterns in caves. We emphasize the common presence of very sharp shapes and spikes, despite the diversity of hydrodynamic conditions and the nature of the soluble materials. We explain the generic emergence of such spikes in dissolution processes by a geometrical approach. Singularities at the interface emerge as a consequence of the erosion directed in the normal direction, when the surface displays curvature variations, like those associated to a dissolution pattern. First, we demonstrate the presence of singular structures in natural interfaces shaped by dissolution. Then, we propose simple surface evolution models of increasing complexity demonstrating the emergence of spikes and allowing us to explain at long term by coarsening the formation of cellular structures. Finally, we perform a dissolution pattern experiment driven by solutal convection and we report the emergence of a cellular pattern following well the model predictions. Although the precise prediction of dissolution shapes necessitates to perform a complete hydrodynamic study, we show that the characteristic spikes which are reported ultimately for dissolution shapes are explained generically by geometrical arguments due to the surface evolution. These findings can be applied to other ablation patterns, reported for example in melting ice.

Mechanisms of asynchronous Ca²⁺ oscillations and their role in (mal)function of vascular smooth muscle
Creators: name: Syyong, Harley Thomas Tan
Publisher: name: University of British Columbia
Year: 2010

description: Contraction of vascular smooth muscle is regulated by fluctuations in the cytosolic concentration of Ca²⁺. The spatio-temporal regulation of Ca²⁺ relies on the subcellular architecture of the smooth muscle cell and the juxtaposition of the opposing plasmalemma, sarcoplasmic reticulum, and mitochondria. This thesis addresses two related aspects of Ca²⁺ signaling in vascular smooth muscle: 1) Reversal of the plasma membrane Na⁺/Ca²⁺ exchanger (NCX) during agonist-mediated stimulation in cultured rat aorta smooth muscle cells, and 2) the primary function of agonist-stimulated asynchronous Ca²⁺ waves and the signaling pathway(s) underlying them in the intact tissue. Evidence for functional coupling of reverse-mode NCX with canonical transient receptor potential channels (TRPC), specifically TRPC6, was provided in rat aortic smooth muscle cells by demonstrating that NCX reversal was increased following stimulation with ATP and 1-Oleoyl-2-acetyl-sn-glycerol, a diacylglycerol analog. However, this was attenuated by blockade of non-selective cation channels with SKF-96365 and by activation of protein kinase C. These data are consistent with the known properties of TRPC6 and further support that functional coupling of TRPC6 and NCX occurs via a receptor-operated cascade. A combination of wire myography and confocal microscopy determined that uridine 5’-triphosphate (UTP)-induced tonic contractions in rat basilar artery were associated with sustained repetitive oscillations in cytosolic Ca²⁺ which propagated along the length of the smooth muscle cells as Ca²⁺ waves. Pharmacological characterization of the mechanism of Ca²⁺ waves revealed that they are a result of repetitive cycles of sarcoplasmic reticulum (SR) Ca²⁺ release via inositol 1,4,5-trisphosphate-sensitive channels followed by the refilling of the SR. Plasmalemmal Ca²⁺ entry via the reverse-mode NCX coupled with the receptor-operated and L-type Ca²⁺ channels is involved in replenishing the SR and supporting the ongoing Ca²⁺ waves. Finally, phenylephrine-stimulated vascular smooth muscle contraction in mesenteric arteries of a mouse model of Marfan syndrome was significantly inhibited and associated with reduced frequency of Ca²⁺ waves. In addition, endothelium-dependent and endothelium-independent vasodilation was impaired, and vessel stiffness was increased. Together, these vasomotor abnormalities in the resistance vessel may have a negative and detrimental impact on the overall cardiovascular function in Marfan syndrome.

description: Time-optimal path planning in high winds for a turning-rate constrained UAV is a challenging problem to solve and is important for deployment and field operations. Previous works have used trochoidal path segments comprising straight and maximum-rate turn segments, as optimal extremal paths in uniform wind conditions. Current methods iterate over all candidate trochoidal trajectory types and select the one that is time-optimal; however, this exhaustive search can be computationally slow. In this paper, we introduce a method to decrease the computation time. This is achieved by reducing the number of candidate trochoidal trajectory types by framing the problem in the air-relative frame and bounding the solution within a subset of candidate trajectories. Our method reduces overall computation by 37.4% compared to pre-existing methods in Bang-Straight-Bang trajectories, freeing up computation for other onboard processes and can lead to significant total computational reductions when solving many trochoidal paths. When used within the framework of a global path planner, faster state expansions help find solutions faster or compute higher-quality paths. We also release our open-source codebase as a C++ package.
