description: Visual counterfactual explanations (VCEs) in image space are an important tool to understand decisions of image classifiers as they show under which changes of the image the decision of the classifier would change. Their generation in image space is challenging and requires robust models due to the problem of adversarial examples. Existing techniques to generate VCEs in image space suffer from spurious changes in the background. Our novel perturbation model for VCEs together with its efficient optimization via our novel Auto-Frank-Wolfe scheme yields sparse VCEs which lead to subtle changes specific for the target class. Moreover, we show that VCEs can be used to detect undesired behavior of ImageNet classifiers due to spurious features in the ImageNet dataset.

description: Recently, deep learning models have made great progress in MWP solving on answer accuracy. However, they are uninterpretable since they mainly rely on shallow heuristics to achieve high performance without understanding and reasoning the grounded math logic. To address this issue and make a step towards interpretable MWP solving, we first construct a high-quality MWP dataset named InterMWP which consists of 11,495 MWPs and annotates interpretable logical formulas based on algebraic knowledge as the grounded linguistic logic of each solution equation. Different from existing MWP datasets, our InterMWP benchmark asks for a solver to not only output the solution expressions but also predict the corresponding logical formulas. We further propose a novel approach with logical prompt and interpretation generation, called LogicSolver. For each MWP, our LogicSolver first retrieves some highly-correlated algebraic knowledge and then passes them to the backbone model as prompts to improve the semantic representations of MWPs. With these improved semantic representations, our LogicSolver generates corresponding solution expressions and interpretable knowledge formulas in accord with the generated solution expressions, simultaneously. Experimental results show that our LogicSolver has stronger logical formula-based interpretability than baselines while achieving higher answer accuracy with the help of logical prompts, simultaneously. The source code and dataset is available at https://github.com/yangzhch6/InterMWP.
Older-child adoption disruption : adoptive couples’ experience
Creators: name: Lytle, Shelagh Anne
Publisher: name: University of British Columbia
Year: 2008

description: The purpose of this study was to conduct an initial exploration of the phenomenon of older child adoption disruption. An account of this lived experience from the perspective of the adoptive couple has been lacking in the literature to date. In an attempt to begin to fill the gap in the literature, a phenomenological research method was utilized. Four couples were recruited from British Columbia for this study. During in-depth audio-taped interviews with each couple, the adoptive parents described their experience of older child adoption disruption. Five common themes were extrapolated from the transcribed data using the four step model of data analysis proposed by Giorgi (1985). The couples in this study reported that their experience of adoption and disruption had a profound long term impact on their lives. The process of adoption disruption appeared to involve the experiences of profound invasiveness, lack of support, erosion of confidence, resignation and loss, and integration and healing. Implications for counselling and for further research were included in the discussion.

description: In the scope of this essay a network for collecting water quality measurements in real time "Andromeda" was developed and deployed. Having at hand the numerous data that were collected on-line we were able to develop a smart system that not only monitors the environmental pollution but also includes Early Warning techniques to predict upcoming natural disasters. The next stage was to develop techniques and algorithms that successfully predict measurements of the water quality. In general the algorithms that were developed during this essay implement solution for knowledge systems, Machine learning systems and Adaptive filters.
Far Field Monitoring of Rogue Nuclear Activity with an Array of Large anti-neutrino Detectors

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: The result of a study on the use of an array of large anti-neutrino detectors for the purpose of monitoring rogue nuclear activity is presented. Targeted regional monitoring of a nation bordering large bodies of water with no pre-existing legal nuclear activity may be possible at a cost of about several billion dollars, assuming several as-yet-untested schemes pan out in the next two decades. These are: (1) the enabling of a water-based detector to detect reactor anti-neutrinos by doping with GdCl$_3$; (2) the deployment of a KamLAND-like detector in a deep-sea environment; and (3) the scaling of a Super-Kamiokande-like detector to a size of one or more megatons. The first may well prove feasible, and should be tested by phase-III Super-Kamiokande in the next few years. The second is more of a challenge, but may well be tested by the Hanohano collaboration in the coming decade. The third is perhaps the least certain, with no schedule for construction of any such device in the foreseeable future. In addition to the regional monitoring scheme, several global, untargeted monitoring schemes were considered. All schemes were found to fail benchmark sensitivity levels by a wide margin, and to cost at least several trillion dollars.

description: Speaker attribution is required in many real-world applications, such as meeting transcription, where speaker identity is assigned to each utterance according to speaker voice profiles. In this paper, we propose to solve the speaker attribution problem by using graph-based semi-supervised learning methods. A graph of speech segments is built for each session, on which segments from voice profiles are represented by labeled nodes while segments from test utterances are unlabeled nodes. The weight of edges between nodes is evaluated by the similarities between the pretrained speaker embeddings of speech segments. Speaker attribution then becomes a semi-supervised learning problem on graphs, on which two graph-based methods are applied: label propagation (LP) and graph neural networks (GNNs). The proposed approaches are able to utilize the structural information of the graph to improve speaker attribution performance. Experimental results on real meeting data show that the graph based approaches reduce speaker attribution error by up to 68% compared to a baseline speaker identification approach that processes each utterance independently.

Σκοπός της μελέτης ήταν η διερεύνηση της ενδεχόμενης συσχέτισης μεσολαβητών της φλεγμονώδους αντίδρασης, όπως οι φλεγμονώδεις κυτταροκίνες IL-6 και TNF-α και τα μόρια προσκόλλησης των ενδοθηλιακών κυττάρων ICAM-1 και VCAM-1, με τις αθηροσκληρωτικές αγγειακές αλλοιώσεις σε ασθενείς με ΧΝΝ 5ου σταδίου υπό συντηρητική αγωγή ή υπό εξωνεφρική κάθαρση (αιμοκάθαρση ή περιτοναϊκή κάθαρση). Ακόμη, σε προοπτική μελέτη, διερευνήθηκε η συσχέτιση των παραπάνω παραγόντων με την εξέλιξη της αθηροσκλήρωσης, αλλά και την εμφάνιση καρδιαγγειακών συμβαμάτων. Στη μελέτη εντάχθηκαν 58 ασθενείς με ΧΝΝ 5ου σταδίου υπό συντηρητική αγωγή, 72 ασθενείς υπό αιμοκάθαρση, 67 ασθενείς υπό περιτοναϊκή κάθαρση και 68 φαινομενικά υγιείς εθελοντές. Η βαρύτητα και η έκταση των αθηροσκληρωτικών αγγειακών αλλοιώσεων εκτιμήθηκε με υπερηχογραφική μέτρηση του πάχους του έσω και μέσου χιτώνα (ΙΜΤ) και του δείκτη αθηροσκληρωτικών πλακών (PS) των καρωτίδων και των μηριαίων αρτηριών. Οι αθηροσκληρωτικές αλλοιώσεις παρουσίαζαν συσχετίσεις μόνο με παραδοσιακούς παράγοντες κινδύνου στην ομάδα ελέγχου, όχι όμως και στις ομάδες των ασθενών, όπου οι φλεγμονώδεις κυτταροκίνες και τα μόρια προσκόλλησης είχαν πολύ ισχυρότερες συσχετίσεις, τόσο με τις πρώιμες (ΙΜΤ) όσο και με τις πιο προχωρημένες (PS) αθηροσκληρωτικές βλάβες αλλά και με το ρυθμό μεταβολής τους. Η διέγερση της συστηματικής φλεγμονώδους αντίδρασης παίζει σημαντικό ρόλο στην βαριά αθηροσκλήρωση των ουραιμικών ασθενών
description: The aim of the present study was to investigate the probable associations between mediators of the inflammatory response and the extent and severity of the atherosclerotic vascular changes in patients with CKD-stage 5. Moreover, in a follow-up study, the associations between the above factors and the progression of atherosclerosis and the development of cardiovascular events were investigated. The study included 58 patients with CKD stage 5 on conservative treatment, 72 patients on chronic hemodialysis, 67 patients on peritoneal dialysis and 68 apparently healthy volunteers who were used as controls. The extent and the severity of atherosclerotic vascular lesions was assessed in all subjects by measuring intima-media thickness and plaque score in the carotid (cIMT and cPS respectively) and femoral (fIMT and fPS respectively) arteries using an ultrasound scanner. Ultrasonographic measurements were repeated after a period of 12-21 months and the rate of progression per year was calculated. Finally, in patients on renal replacement therapy, the cardiovascular events during the above follow-up period were recorded

Field-Driven Hysteresis of the d=3 Ising Spin Glass: Hard-Spin Mean-Field Theory

description: Hysteresis loops are obtained in the Ising spin-glass phase in d=3, using frustration-conserving hard-spin mean-field theory. The system is driven by a time-dependent random magnetic field H_Q that is conjugate to the spin-glass order Q, yielding a field-driven first-order phase transition through the spin-glass phase. The hysteresis loop area A of the Q-H_Q curve scales with respect to the sweep rate h of magnetic field as A-A_0 = h^b. In the spin-glass and random-bond ferromagnetic phases, the sweep-rate scaling exponent b changes with temperature T, but appears not to change with antiferromagnetic bond concentration p. By contrast, in the pure ferromagnetic phase, b does not depend on T and has a sharply different value than in the two other phases.

description: Gas-phase processes were long thought to be the key formation mechanisms for complex organic molecules in star-forming regions. However, recent experimental and theoretical evidence has cast doubt on the efficiency of such processes. Grain-surface chemistry is frequently invoked as a solution, but until now there have been no quantitative models taking into account both the high degree of chemical complexity and the evolving physical conditions of star-forming regions. Here, we introduce a new gas-grain chemical network, wherein a wide array of complex species may be formed by reactions involving radicals. The radicals we consider (H, OH, CO, HCO, CH3, CH3O, CH2OH, NH and NH2) are produced primarily by cosmic ray-induced photodissociation of the granular ices formed during the colder, earlier stages of evolution. The gradual warm-up of the hot core is crucial to the formation of complex molecules, allowing the more strongly-bound radicals to become mobile on grain surfaces. This type of chemistry is capable of reproducing the high degree of complexity seen in Sgr B2(N), and can explain the observed abundances and temperatures of a variety of previously detected complex organic molecules, including structural isomers. Many other complex species are predicted by this model, and several of these species may be detectable in hot cores. Differences in the chemistry of high- and low-mass star-formation are also addressed; greater chemical complexity is expected where evolution timescales are longer.

RG Flows and Dynamical Systems

description: In the context of Wilsonian Renormalization, renormalization group (RG) flows are a set of differential equations that defines how the coupling constants of a theory depend on an energy scale. These equations closely resemble thermodynamical equations and how thermodynamical systems are related to temperature. In this sense, it is natural to look for structures in the flows that show a thermodynamics-like behaviour. The mathematical theory to study these equations is called Dynamical Systems, and applications of that have been used to study RG flows. For example, the classical Zamolodchikov's C-Theorem and its higher-dimensional counterparts, that show that there is a monotonically decreasing function along the flow and it is a property that resembles the second-law of thermodynamics, is related to the Lyapunov function in the context of Dynamical Systems. It can be used to rule out exotic asymptotic behaviours like periodic flows (also known as limit cycles). We also study bifurcation theory and index theories, which have been proposed to be useful in the study of RG flows, the former can be used to explain couplings crossing through marginality and the latter to extract global information about the space the flows lives in. In this dissertation, we also look for applications in holographic RG flows and we try to see if the structural behaviours in holographic theories are the same as the ones in the dual field theory side.

Stress, attributions, and coping : predictors of emotional exhaustion in male post-secondary instructors
Creators: name: Stephens, Eileen
Publisher: name: University of British Columbia
Year: 2008

description: This study used a learned-helplessness model to examine burnout. Two hierarchical multiple regression analyses tested the extent to which job stress, attribution style, and coping strategies were associated with burnout (i.e., emotional exhaustion) in male instructors (N = 108), aged 30 and 55 (M = 44.1), employed at a post-secondary institution in western Canada. It was expected that those attribution styles and coping strategies associated with greater "personal" and "universal" helplessness would be associated with greater emotional exhaustion, whereas those associated with greater "morale" and "enthusiasm" would be associated with lower emotional exhaustion Specifically , greater characterological (internal-stable) and task difficulty (external-stable) attributions were expected to be associated with greater emotional exhaustion under high-stress conditions. Under low-stress conditions, greater behavioural (internal-unstable) attributions were expected to be associated with greater emotional exhaustion. Greater emotional exhaustion was also expected to be associated with greater escape-cognitive and escape-active coping ratios, but with lower control-cognitive and control-active coping ratios. Those attribution styles and coping strategies associated with personal helplessness, i.e, characterological (internal-stable) attributions and escape-cognitive coping, were expected to make stronger contributions to emotional exhaustion than were those associated with universal helplessness, i.e., task difficulty (external-stable) attributions and escape-active coping. In addition, control-cognitive coping was expected to be more negatively associated with emotional exhaustion than was control-active coping. Results indicated that greater escape-active coping was associated with greater emotional exhaustion. The contribution of the universal-helplessness product-term (stress by externalstable attributions) approached significance. Under high-stress conditions, greater task difficulty (external-stable) attributions were associated with greater emotional exhaustion. The enthusiasm product-term (stress by internal-unstable attributions) also contributed significantly to emotional exhaustion. Under low-stress conditions, greater behavioural (internal-unstable) attributions were associated with greater emotional exhaustion. The negative association between control-cognitive coping and emotional exhaustion approached significance. Results suggested that burnout may involve universal rather than personal helplessness. This finding was not anticipated. Results also supported the theory that internal-unstable (behavioural) attributions may represent a vulnerability to burnout. Longitudinal studies would need to be conducted to test any causal implications of the present findings.

description: Theory of hole magnetization Mc in zinc-blende diluted ferromagnetic semiconductors is developed relaxing the spherical approximation of earlier approaches. The theory is employed to determine Mc for (Ga,Mn)As over a wide range of hole concentrations and a number of crystallographic orientations of Mn magnetization. It is found that anisotropy of Mc is practically negligible but the obtained magnitude of Mc is significantly greater than that determined in the spherical approximation. Its sign and value compares favorably with the results of available magnetization measurements and ferromagnetic resonance studies.

description: In this work we define a new limiting procedure that extends the usual thermodynamics treatment of Black Hole physics, to the supersymmetric regime. This procedure is inspired on equivalent statistical mechanics derivations in the dual CFT theory, where the BPS partition function at zero temperature is obtained by a double scaling limit of temperature and the relevant chemical potentials. In supergravity, the resulting partition function depends on emergent generalized chemical potentials conjugated to the different conserved charges of the BPS solitons. With this new approach, studies on stability and phase transitions of supersymmetric solutions are presented. We find stable and unstable regimes with first order phase transitions, as suggested by previous studies on free supersymmetric Yang Mills theory.

description: Barrow proposed that the area law of the entropy associated with a horizon might receive a "fractal correction" due to quantum gravitational effects -- in place of $S\propto A$, we have instead $S\propto A^{1+δ/2}$, where $0\leqslant δ\leqslant 1$ measures the deviation from the standard area law ($δ=0$). Based on black hole thermodynamics, we argue that the Barrow entropy should run (i.e., energy scale dependent), which is reasonable given that quantum gravitational corrections are expected to be important only in high energy regime. When applied to the Friedmann equation, we demonstrate the possibility that such a running Barrow entropy index could give rise to a dynamical effective dark energy, which is asymptotically positive and vanishing, but negative at the Big Bang. Such a sign switching dark energy could help to alleviate the Hubble tension. Other cosmological implications are discussed.

description: In this paper we introduce the Dirac and spin-Dirac operators associated to a connection on Riemann-Cartan space(time) and standard Dirac and spin-Dirac operators associated with a Levi-Civita connection on a Riemannian (Lorentzian) space(time) and calculate the square of these operators, which play an important role in several topics of modern Mathematics, in particular in the study of the geometry of moduli spaces of a class of black holes, the geometry of NS-5 brane solutions of type II supergravity theories and BPS solitons in some string theories. We obtain a generalized Lichnerowicz formula, decompositions of the Dirac and spin-Dirac operators and their squares in terms of the standard Dirac and spin-Dirac operators and using the fact that spinor fields (sections of a spin-Clifford bundle) have representatives in the Clifford bundle we present also a noticeable relation involving the spin-Dirac and the Dirac operators.

description: We carried out a one-night optical V and near-infrared JHK monitoring observation of the least luminous Seyfert 1 galaxy, NGC4395, on 2004 May 1, and detected for the first time the intraday flux variations in the J and H bands, while such variation was not clearly seen for the K band. The detected J and H variations are synchronized with the flux variation in the V band, which indicates that the intraday-variable component of near-infrared continuum emission of the NGC4395 nucleus is an extension of power-law continuum emission to the near-infrared and originates in an outer region of the central accretion disk. On the other hand, from our regular program of long-term optical BVI and near-infrared JHK monitoring observation of NGC4395 from 2004 February 12 until 2005 January 22, we found large flux variations in all the bands on time scales of days to months. The optical BVI variations are almost synchronized with each other, but not completely with the near-infrared JHK variations. The color temperature of the near-infrared variable component is estimated to be T=1320-1710 K, in agreement with thermal emission from hot dust tori in active galactic nuclei (AGNs). We therefore conclude that the near-infrared variation consists of two components having different time scales, so that a small K-flux variation on a time scale of a few hours would possibly be veiled by large variation of thermal dust emission on a time scale of days.

description: We analyze equilibrium spin currents in a 2D electron gas with Rashba spin-orbit interaction (Rashba medium). In a uniform Rashba medium these currents are constant, and their ability to really transport spin is not evident. But even weak inhomogeneity of the Rashba medium allows to reveal that equilibrium spin currents can transport spin from areas where spin is produced to areas where spin is absorbed.

Psychotherapeutic factors of naturally occurring long-term meditation
Creators: name: Lawrance, Scott
Publisher: name: University of British Columbia

description: Various forms of meditation are being used by an increasing number of people in North America. Practiced both within the context of an overarching spiritual path and as a self-regulation strategy, meditation is sometimes a supplement to traditional forms of psychotherapy. At other times, meditation, as part of a spiritual practice, is used as an alternative approach to mental health and well-being. A multiple case study research format is used to understand the pattern of experience involved in long-term meditation from the perspective of the meditators. Five meditators were interviewed for their accounts of their experience with meditation over a minimum of ten years. The interviews were organized into five narrative accounts and summarized as a general account which in turn revealed twelve common themes. The stories take the form of a movement from alienation and estrangement, through struggle and problem solving, toward an eventual consolidation of meaning and engagement with the world. This movement is accomplished through the resolution of three major tasks: the clarification of the relationship with the teacher; mastery of the techniques involved; and a cognitive restructuring based upon the optimal resolution of the first two tasks. Theoretical implications of the study, such as various relationships between meditation and psychotherapy, are presented. Finally, the practical implications of the study for general counselling, counselling with meditators, and counsellor growth are discussed.

description: The present thesis explores the educational value systems in foreign language syllabi through the use of a modular typology that records the traits of the axes that the construction of these syllabi is based on. The aim is to identify the true ideological orientation of language syllabi and these points where there is possible mismatch between stated targets and suggested teaching approaches for their accomplishment. This would offer the possibility of intervention at the level of language planning for a more effective application of the syllabi.

description: We consider a few-particle system of trapped neutral fermionic atoms at ultra-low temperatures, with the attractive interaction tuned to Feshbach resonance. We calculate the energies and the spatial densities of the few-body systems using a generalisation of the extended Thomas-Fermi (ETF) method, and assuming the particles obey the Haldane-Wu fractional exclusion statistics (FES) at unitarity. This method is different from the scaled ETF version given by Chang and Bertsch (Phys. Rev. A76,021603(R) (2007)). Our semiclassical FES results are consistent with the Monte-Carlo calculations of the above authors, but can hardly be distinguished from their over all scaling of the ETF result at unitarity.

description: Considering feedback of collective actions of cooperation on common resources has vital importance to reach sustainability. But such efforts may have not immediate consequence on the state of environment and it is unclear how they influence the strategic and environmental dynamics with feedbacks. To address this issue, we construct a feedback-evolving game model in which we consider the growth capacity of resources and the punishment efficiency on defectors who do not provide returns to the environment. Importantly, we further assume a delay in adopting the contribution of cooperative individuals to environmental change in our model. We find that when this contribution amount from cooperators' endowment is fixed, the time delay has no particular consequence on the coevolutionary dynamics. However, when the return is proportional to their endowment, then the time delay can induce periodic oscillatory dynamics of cooperation level and environment. Our work reveals the potential effects of time delay of cooperative actions on the coevolutionary dynamics in strategic interactions with environmental feedback.

description: We consider high density quark matter in the large $\N_c$ and $\N_f$ limit with $\N_f/\N_c$ fixed. In this limit, the color superconductivity disappears. We discuss that the chiral density wave state is also absent in the limit, if we assume the existence of the non-perturbative magnetic screening effect as indicated by recent lattice study. We argue that ferromagnetism can become a candidate for the ground state if quarks are massive.

Fermi Liquid Theory for the Persistent Current Past a Side-Coupled Quantum Dot

description: A Fermi Liquid theory is developed for the persistent current past a side coupled quantum dot yielding analytical predictions for the behavior of the first two harmonics of the persistent current as a function of applied magnetic flux. The quantum dot is assumed weakly coupled to a ring of non-interacting electrons and thus appropriately described as a Kondo impurity. The theory is valid at weak Kondo couplings in the regime where the system size, L, is much larger than the size of the Kondo screening cloud, xi_K. The predictions of the Fermi Liquid theory are compared to exact diagonalization results for the persistent current that lend support to the existence of a regime correctly described by this theory. The finite temperature conductance, at T << T_K is also calculated using Fermi liquid theory allowing the definition of a ``Wilson ratio" relating the conductance and the persistent current.

description: The paper studies a single-server queueing system with autonomous service and $\ell$ priority classes. Arrival and departure processes are governed by marked point processes. There are $\ell$ buffers corresponding to priority classes, and upon arrival a unit of the $k$th priority class occupies a place in the $k$th buffer. Let $N^{(k)}$, $k=1,2,...,\ell$ denote the quota for the total $k$th buffer content. The values $N^{(k)}$ are assumed to be large, and queueing systems both with finite and infinite buffers are studied. In the case of a system with finite buffers, the values $N^{(k)}$ characterize buffer capacities. The paper discusses a circle of problems related to optimization of performance measures associated with overflowing the quota of buffer contents in particular buffers models. Our approach to this problem is new, and the presentation of our results is simple and clear for real applications.

description: We present an algorithm for reliably and systematically proving the existence of spectral gaps in Hamiltonians with quasicrystalline order, based on numerical calculations on finite domains. We apply this algorithm to prove that the Hofstadter model on the Ammann-Beenker tiling of the plane has spectral gaps at certain energies, and we are able to prove the existence of a spectral gap where previous numerical results were inconclusive. Our algorithm is applicable to more general systems with finite local complexity and eventually finds all gaps, circumventing an earlier no-go theorem regarding the computability of spectral gaps for general Hamiltonians.

description: Observing the significance of spectrally-efficient secure non-orthogonal multiple access (NOMA), this paper proposes a novel quality of service (QoS) aware secure NOMA protocol that maximizes secrecy fairness among untrusted users. Considering a base station (BS) and two users, a novel decoding order is designed that provides security to both users. With the objective of ensuring secrecy fairness between users, while satisfying their QoS requirements under BS transmit power budget constraint, we explore the problem of minimizing the maximum secrecy outage probability (SOP). Closed-form expression of pair outage probability (POP) and optimal power allocation (PA) minimizing POP are obtained. To analyze secrecy performance, analytical expressions of SOP for both users are derived, and individual SOP minimization problems are solved using concept of generalized-convexity. High signal-to-noise ratio approximation of SOP and asymptotically optimized solution minimizing this approximation is also found. Furthermore, a global-optimal solution from secrecy fairness standpoint is obtained at low computational complexity, and tight approximation is derived to get analytical insights. Numerical results present useful insights on globally optimized PA which ensure secrecy fairness and provide performance gain of about 55.12%, 69.30%, and 19.11%, respectively, compared to fixed PA and individual users' optimal PAs. Finally, a tradeoff between secrecy fairness performance and QoS demands is presented.
