description: Municipal finances have been an ongoing public issue in Alberta. See for example, McMillan and Dahlby (2014), Dahlby and McMillan (2021) and Peterson (2021). These issues have recently become more prominent as the Alberta government has adopted a variety of policies that impact municipal finances as well as announcing plans to transition the Municipal Sustainability Initiative program to the Local Government Fiscal Framework. This has created new uncertainties about municipal finances, especially in the context of provincial government fiscal restraint.

description: Functional Magnetic Resonance Imaging (fMRI) maps cerebral activation in response to stimuli but this activation is often difficult to detect, especially in low-signal contexts and single-subject studies. Accurate activation detection can be guided by the fact that very few voxels are, in reality, truly activated and that these voxels are spatially localized, but it is challenging to incorporate both these facts. We address these twin challenges to single-subject and low-signal fMRI by developing a computationally feasible and methodologically sound model-based approach, implemented in the R package MixfMRI, that bounds the a priori expected proportion of activated voxels while also incorporating spatial context. An added benefit of our methodology is the ability to distinguish voxels and regions having different intensities of activation. Our suggested approach is evaluated in realistic two- and three-dimensional simulation experiments as well as on multiple real-world datasets. Finally, the value of our suggested approach in low-signal and single-subject fMRI studies is illustrated on a sports imagination experiment that is often used to detect awareness and improve treatment in patients in persistent vegetative state (PVS). Our ability to reliably distinguish activation in this experiment potentially opens the door to the adoption of fMRI as a clinical tool for the improved treatment and therapy of PVS survivors and other patients.

description: Brain connectivity network derived from functional magnetic resonance imaging (fMRI) is becoming increasingly prevalent in the researches related to cognitive and perceptual processes. The capability to detect causal or effective connectivity is highly desirable for understanding the cooperative nature of brain network, particularly when the ultimate goal is to obtain good performance of control-patient classification with biological meaningful interpretations. Understanding directed functional interactions between brain regions via brain connectivity network is a challenging task. Since many genetic and biomedical networks are intrinsically sparse, incorporating sparsity property into connectivity modeling can make the derived models more biologically plausible. Accordingly, we propose an effective connectivity modeling of resting-state fMRI data based on the multivariate autoregressive (MAR) modeling technique, which is widely used to characterize temporal information of dynamic systems. This MAR modeling technique allows for the identification of effective connectivity using the Granger causality concept and reducing the spurious causality connectivity in assessment of directed functional interaction from fMRI data. A forward orthogonal least squares (OLS) regression algorithm is further used to construct a sparse MAR model. By applying the proposed modeling to mild cognitive impairment (MCI) classification, we identify several most discriminative regions, including middle cingulate gyrus, posterior cingulate gyrus, lingual gyrus and caudate regions, in line with results reported in previous findings. A relatively high classification accuracy of 91.89 % is also achieved, with an increment of 5.4 % compared to the fully-connected, non-directional Pearson-correlation-based functional connectivity approach.

description: We use 4 galaxies from the Calar Alto Legacy Integral Field Area (CALIFA) survey with clear signs of accretion onto supermassive black holes to investigate the relative contribution of star-formation and active galactic nucleus (AGN) activity to the line-emission of each galaxy as a function of radius. The combination of star-formation and AGN activity produces curved "mixing sequences" on standard optical diagnostic diagrams, and the fraction of emission due to AGN activity decreases smoothly with distance from the centre of the galaxy. We use the AGN activity profiles to calculate the size of the AGN narrow line regions, which have radii of ~ 6.3 kpc. We calculate the fractional contribution of the star-formation and the AGN activity to the global Halpha, [O II] $λλ$ 3727,3729 and [O III] $λ$ 5007 luminosities of each galaxy, and show that both ionization sources contribute significantly to the emission in all three lines. We use weighted combinations of stellar and AGN photoionization models to produce mixing models, which are consistent with observations for 85 percent of spaxels across the galaxies in our sample. We also present a new diagnostic for starburst-AGN mixing which requires only the [O II], [O III] and Hbeta emission lines, and can therefore be used to calculate AGN fractions up to z ~ 0.85 in the optical and z ~ 3.5 in the near-infrared. We anticipate that this diagnostic will facilitate studies of the properties of AGN ionizing radiation fields and the relative optical contribution of star-formation and AGN activity over cosmic time.

Canadian Immigration Policy and the Russo-Ukraine War
Creators: name: Falconer, Robert
Publisher: name: The School of Public Policy Publications

description: Millions of Ukrainians have been displaced since Russia launched a full-scale invasion of Ukraine earlier this year. Yet, Canada has only received a small number of Ukrainian refugees compared to other countries, despite citizens’ overwhelming willingness to receive them. Canadian immigration policies are the issue and need to be revised to allow faster and easier access for Ukrainians. While the federal government has launched a program to fast-track Ukrainian refugees, Canada-Ukraine Authorization for Emergency Travel (CUAET), statistics show that it isn’t enough. Under CUAET, visas and temporary residency permits are expedited for Ukrainians and their families. While the number of applications is increasing, the program’s number of approvals is slowing. That Canadian visa policies are the cause of the comparatively low number of Ukrainian arrivals is supported by empirical evidence from Ireland and the United Kingdom. Both countries are similar in ways that attract displaced Ukrainians, but only Ireland lifted its visa requirements in response to the war; the U.K. has maintained a Canada-like visa process. As a result, approximately 13 times the number of Ukrainian refugees per capita arrived in Ireland than in the U.K. during the first two months of the invasion. The visa requirements in Canada have, in a similar way, stymied the arrival of Ukrainian refugees. There are several options that could be implemented to increase the flow of Ukrainian refugees to Canada. The first, visa-free travel, is already in place in Ireland and has proven very successful, allowing an additional estimated 23,000 arrivals above what might have been expected under pre-war Irish visa policies. The second is a visa-on-arrival system. Security checks are done at the port-of-entry and a visa can be issued onsite. The third option is a hybrid of CUAET and options 1 or 2 — allow visa-free travel or a visa-on-arrival program for Ukrainians with proper documentation while those without documentation go through CUAET. This will speed up the CUAET process since documented refugees will not be part of the list anymore. National security concerns are one of the reasons for Canada’s more strict immigration policies. However, research shows that foreign agents are less likely to infiltrate strong, stable countries through refugee streams. As well, refugees tend to be targets of espionage themselves and can be a valuable source of intelligence. Canada could invest more in counterespionage to help identify high-risk entries and mitigate the small risk of infiltration. Approximately 80 per cent of Canadians are willing for this country to receive Ukrainian refugees. The chance of refugee-related espionage is minuscule while the impact of Canada’s humanitarianism is huge. The federal government needs to consider this trade-off and amend immigration policies for Ukrainian war refugees.

description: Research on an early detection of Mild Cognitive Impairment (MCI), a prodromal stage of Alzheimer’s Disease (AD), with resting-state functional Magnetic Resonance Imaging (rs-fMRI) has been of great interest for the last decade. Witnessed by recent studies, functional connectivity is a useful concept in extracting brain network features and finding biomarkers for brain disease diagnosis. However, it still remains challenging for the estimation of functional connectivity from rs-fMRI due to the inevitable high dimensional problem. In order to tackle this problem, we utilize a group sparse representation along with a structural equation model. Unlike the conventional group sparse representation method that does not explicitly consider class-label information, which can help enhance the diagnostic performance, in this paper, we propose a novel supervised discriminative group sparse representation method by penalizing a large within-class variance and a small between-class variance of connectivity coefficients. Thanks to the newly devised penalization terms, we can learn connectivity coefficients that are similar within the same class and distinct between classes, thus helping enhance the diagnostic accuracy. The proposed method also allows the learned common network structure to preserve the network specific and label-related characteristics. In our experiments on the rs-fMRI data of 37 subjects (12 MCI; 25 healthy normal control) with a cross-validation technique, we demonstrated the validity and effectiveness of the proposed method, showing the diagnostic accuracy of 89.19% and the sensitivity of 0.9167.

description: A sweep of a point configuration is any ordered partition induced by a linear functional. Posets of sweeps of planar point configurations were formalized and abstracted by Goodman and Pollack under the theory of allowable sequences of permutations. We introduce two generalizations that model posets of sweeps of higher dimensional configurations. Mimicking the fact that sweep polytopes of point configurations (the monotone path polytopes of the associated zonotopes) are projections of permutahedra, we define sweep oriented matroids as strong maps of the braid oriented matroid. Allowable sequences are then the sweep oriented matroids of rank 2, and many of their properties extend to higher rank. We show strong ties between sweep oriented matroids and both modular hyperplanes and Dilworth truncations from (unoriented) matroid theory. We also explore their connection with the generalized Baues problem for cellular strings, where sweep oriented matroids can play the role of monotone path polytopes, even for non-realizable oriented matroids. In particular, we show that for oriented matroids that admit a sweep oriented matroid, their poset of pseudo-sweeps deformation retracts to a sphere of the appropriate dimension. A second generalization are allowable graphs of permutations: symmetric sets of permutations pairwise connected by allowable sequences. They have the structure of acycloids and include sweep oriented matroids.

description: Far-Infrared (FIR) photometry from the the Photodetector Array Camera and Spectrometer (PACS) on the Herschel Space Observatory is presented for 313 nearby, hard X-ray selected galaxies from the 58-month Swift Burst Alert Telescope (BAT) Active Galactic catalog. The present data do not distinguish between the FIR luminosity distributions at 70 and 160um for Seyfert 1 and Seyfert 2 galaxies. This result suggests that if the FIR emission is from the nuclear obscuring material surrounding the accretion disk, then it emits isotropically, independent of orientation. Alternatively, a significant fraction of the 70 and 160um could be from star formation, independent of AGN type. Using a non-parametric test for partial correlation with censored data, we find a statistically significant correlation between the AGN intrinsic power (in the 14-195 keV band ) and the FIR emission at 70 and 160um for Seyfert 1 galaxies. We find no correlation between the 14-195 keV and FIR luminosities in Seyfert 2 galaxies. The observed correlations suggest two possible scenarios: (i) if we assume that the FIR luminosity is a good tracer of star formation, then there is a connection between star formation and the AGN at sub-kiloparsec scales, or (ii) dust heated by the AGN has a statistically significant contribution to the FIR emission. Using a Spearman rank-order analysis, the 14-195 keV luminosities for the Seyfert 1 and 2 galaxies are weakly statistically correlated with the F70/F160 ratios.

description: Given the severity of their illness and lack of effective disease modifying agents, it is not surprising that most patients with ALS consider trying complementary and alternative therapies. Some of the most commonly considered alternative therapies include special diets, nutritional supplements, cannabis, acupuncture, chelation and energy healing. This chapter reviews these in detail. We also describe 3 models by which physicians may frame discussions about alternative therapies: paternalism, autonomy and shared decision making. Finally, we review a program called ALSUntangled which using shared shared decision making to review alternative therapies for ALS.

Income Support, Inflation, and Homelessness

Publisher: name: The School of Public Policy Publications
Year: 2022

description: In this note, we provide measures of the effects of high rates of inflation in food prices and the costs of housing on Canadian households reliant on government-provided income assistance. Inflation puts these households at risk because little of their income is indexed to inflation. That which is indexed to inflation varies by province and by family composition. In most provinces, protection from inflation depends on periodic ad hoc adjustments to income support payments, adjustments that are sometimes separated by many years. A notable exception is Quebec, where nearly full indexation ensures recipients of income support are protected from inflation. In other provinces, the general lack of full indexation means that during periods of inflation, Canadians reliant on social assistance are subject to two types of risk, one economic and one political. The economic risk is due to the fact inflation threatens to cause them to endure a catastrophic fall in what is already a low standard of living. The political risk arises because in most provinces, whether inflation results in a fall in living standards is entirely dependent upon whether politicians choose to provide periodic, unscheduled increases in social assistance incomes, euphemistically referred to as income “enrichments.” With a single stroke of a legislative pen the political risk can be eliminated and the economic risk minimized. The high rates of inflation currently being experienced add urgency to this consideration. We show that deteriorating health, increased reliance on food banks and rising rates of homelessness are just some of the inevitable consequences of delay.

description: Let $\boldsymbol{X}$ be a $d$-dimensional random array on $[n]$ whose entries take values in a finite set $\mathcal{X}$, that is, $\boldsymbol{X}=\langle X_s:s\in \binom{[n]}{d}\rangle$ is an $\mathcal{X}$-valued stochastic process indexed by the set $\binom{[n]}{d}$ of all $d$-element subsets of $[n]:=\{1,\dots,n\}$. We give easily checked conditions on $\boldsymbol{X}$ that ensure, for instance, that for every function $f\colon \mathcal{X}^{\binom{[n]}{d}}\to\mathbb{R}$ that satisfies $\mathbb{E}[f(\boldsymbol{X})]=0$ and $\|f(\boldsymbol{X})\|_{L_p}=1$ for some $p>1$, the random variable $f(\boldsymbol{X})$ becomes concentrated after conditioning it on a large subarray of $\boldsymbol{X}$. These conditions cover several classes of random arrays with not necessarily independent entries. Applications are given in combinatorics, and examples are also presented that show the optimality of various aspects of the results.

description: The coherent dynamics of relaxing spin qubits driven by a classical bichromatic field comprising a strong resonant component and a weaker component with a frequency close to the strong-field Rabi frequency is studied. The double dressing by the bichromatic field modifies dephasing and dissipation processes. We demonstrate that detuning of the weaker-field frequency from the strong-field Rabi frequency prolongs the decay of Rabi oscillations between some doubly dressed states. The sensitivity of Rabi oscillations to the modified detuning-dependent relaxation is illustrated for nitrogen-vacancy qubits in diamond. We discuss a steady-state population inversion of the doubly dressed-state levels.

description: The electroencephalographic (EEG) signals provide highly informative data on brain activities and functions. However, their heterogeneity and high dimensionality may represent an obstacle for their interpretation. The introduction of a priori knowledge seems the best option to mitigate high dimensionality problems, but could lose some information and patterns present in the data, while data heterogeneity remains an open issue that often makes generalization difficult. In this study, we propose a genetic algorithm (GA) for feature selection that can be used with a supervised or unsupervised approach. Our proposal considers three different fitness functions without relying on expert knowledge. Starting from two publicly available datasets on cognitive workload and motor movement/imagery, the EEG signals are processed, normalized and their features computed in the time, frequency and time-frequency domains. The feature vector selection is performed by applying our GA proposal and compared with two benchmarking techniques. The results show that different combinations of our proposal achieve better results in respect to the benchmark in terms of overall performance and feature reduction. Moreover, the proposed GA, based on a novel fitness function here presented, outperforms the benchmark when the two different datasets considered are merged together, showing the effectiveness of our proposal on heterogeneous data.

description: In 1991, the AIDS Task Force of the American Academy of Neurology published nomenclature and research case definitions to guide the diagnosis of neurologic manifestations of HIV-1 infection. Now, 16 years later, the National Institute of Mental Health and the National Institute of Neurological Diseases and Stroke have charged a working group to critically review the adequacy and utility of these definitional criteria and to identify aspects that require updating. This report represents a majority view, and unanimity was not reached on all points. It reviews our collective experience with HIV-associated neurocognitive disorders (HAND), particularly since the advent of highly active antiretroviral treatment, and their definitional criteria; discusses the impact of comorbidities; and suggests inclusion of the term asymptomatic neurocognitive impairment to categorize individuals with subclinical impairment. An algorithm is proposed to assist in standardized diagnostic classification of HAND.

description: The emittance growth in the HL-LHC due to beam-beam effects is examined by virtue of strong-strong computer simulations. A model of the transverse damper and the noise level have been tuned to simulate the emittance growth in the present LHC. Simulations with projected HL-LHC beam parameters and crab cavities are discussed. It is shown that with the nominal working point, the large beam-beam tune shift moves the beam into a resonance that causes substantial emittance growth. Increasing the working point slightly is demonstrated to be very beneficial.

description: Kinematic dynamo in incompressible isotropic turbulent flows with high magnetic Prandtl number is considered. The approach interpreting an arbitrary magnetic field distribution as a superposition of localized perturbations (blobs) is proposed. We derive a relation between stochastic properties of a blob and a stochastically homogenous distribution of magnetic field advected by the same stochastic flow. This relation allows to investigate the evolution of a localized blob at late stage when its size exceeds the viscous scale. It is shown that in 3-dimansional flows, the average magnetic field of the blob increases exponentially in the inertial range of turbulence, as opposed to the late-Batchelor stage when it decreases. Our approach reveals the mechanism of dynamo generation in the inertial range both for blobs and homogenous contributions. It explains the absence of dynamo in the two-dimensional case and its efficiency in three dimensions. We propose the way to observe the mechanism in numerical simulations.

description: About 20% of familial amyotrophic lateral sclerosis (ALS) is caused by mutations in SOD1 and is typically transmitted as an autosomal dominant trait. However, due to reduced mutation penetrance, the disease may present in a recessive or sporadic manner. To determine the factors responsible for the low penetrance of the SOD1 mutation. Twelve members of a Canadian ALS family of Filipino origin were recruited for the study. SOD1 was sequenced in the proband. SOD1 expression was assessed by real-time-PCR and immunoblotting. The proband was a homozygous carrier of a novel 6 bp deletion in exon 2 (DeltaG27/P28), the pathologic significance of which was confirmed by immunohistochemistry. Eight living family members are heterozygotes and remain unaffected at ages ranging between 48 and 85 years. Haplotype analysis showed that the deletion is a single founder mutation likely common in the Cagayan province (Philippines). The low penetrance of the mutation is explained by the fact that it enhances the naturally occurring alternative splicing of exon 2 of the SOD1 mRNA, leading to reduced transcription of the mutant allele. Indeed, Western blot analysis demonstrated the low level of SOD1 protein in carriers of the DeltaG27/P28 compared to wild-type individuals or a carrier of the A4V SOD1 mutation. The enhanced splicing of exon 2 acts as a natural knock-down of the mutant SOD1 allele in the Filipino amyotrophic lateral sclerosis (ALS) family. There is a need for careful investigation of splicing isoforms of SOD1 and other ALS genes as factors influencing the severity of disease.
Feature Generalization in Deep Reinforcement Learning: An Investigation into Representation Properties
Creators: Miahi, Erfan

In this thesis, we investigate the connection between the properties and the generalization performance of representations learned by deep reinforcement learning algorithms. Much of the earlier work on representation learning for reinforcement learning focused on designing fixed-basis architectures to achieve properties thought to be desirable, such as orthogonality and sparsity. In contrast, the idea behind deep reinforcement learning methods is that the agent designer should not encode representational properties, but rather that the data stream should determine the properties of the representation---good representations emerge under appropriate training schemes. We bring these two perspectives together, empirically investigating the properties of representations that are good at generalization in reinforcement learning. This analysis allows us to provide novel hypotheses regarding the impact of auxiliary tasks in end-to-end training of deep reinforcement learning methods. We introduce and measure six representational properties over more than 28 thousand agent-task settings. We consider DQN agents with convolutional networks in a pixel-based navigation environment.  We develop a method to better understand why some representations improve generalization, through a systematic approach varying task similarity and measuring and correlating representation properties with generalization performance. Using this insight, we design two novel auxiliary losses and show that they generalize as well as our best baselines.

description: BACKGROUND: The frequency of HIV dementia in a recent study of HIV+ individuals at the Infectious Disease Institute in Kampala, Uganda, was 31%. Coformulated generic drugs, which include stavudine, are the most common regimens to treat HIV infection in Uganda and many other parts of Africa.

OBJECTIVE: To evaluate the benefits and risks of stavudine-based highly active antiretroviral therapy (HAART) for HIV-associated cognitive impairment and distal sensory neuropathy. The study compared neuropsychological performance changes in HIV+ individuals initiating HAART for 6 months and HIV- individuals receiving no treatment for 6 months. The risk of antiretroviral toxic neuropathy as a result of the initiation of stavudine-based HAART was also examined.

METHODS: At baseline, 102 HIV+ individuals in Uganda received neurologic, neuropsychological, and functional assessments; began HAART; and were followed up for 6 months. Twenty-five HIV- individuals received identical clinical assessments and were followed up for 6 months.

RESULTS: In HIV+ individuals, there was improvement in verbal memory, motor and psychomotor speed, executive thinking, and verbal fluency. After adjusting for differences in sex, HIV+ individuals demonstrated significant improvement in the Color Trails 2 test (p = 0.025) compared with HIV- individuals. Symptoms of neuropathy developed in 38% of previously asymptomatic HIV+ patients after initiation of the stavudine-based HAART.

CONCLUSIONS: After the initiation of highly active antiretroviral therapy (HAART) including stavudine, HIV+ individuals with cognitive impairment improve significantly as demonstrated by improved performance on a test of executive function. However, peripheral neurotoxicity occurred in 30 patients, presumably because of stavudine-based HAART, suggesting the need for less toxic therapy.
Subcortical Volume and Executive Functions in Children with Attention-Deficit/Hyperactivity Disorder (ADHD)

Background. The subcortical regions, including the caudate and putamen, have been historically implicated in pediatric Attention-Deficit/Hyperactivity Disorder (ADHD). Along with differences in subcortical regions, children with ADHD generally show weaker executive function (EF). However, previous studies have not investigated the relationship between the caudate and putamen volume with EF. The current study investigated the clinical relevance of the caudate and putamen with respect to EF as measured through cognitive performance-based tasks and parent ratings of EF.

Method. Twenty-four children with ADHD (M =11.64; males =12) and 25 typically developing children (TDC; M = 11.09 years; males =14) underwent a high-resolution Magnetic Resonance Imaging (MRI) T1-weighted sequence. FreeSurfer 6.0 was used for subcortical volume reconstruction. Children with ADHD completed EF tasks related to working memory and inhibition. Parents completed behaviour rating scales measuring executive function (BRIEF-2). Data were analyzed using Multivariate Analysis of Variance, Multivariate Analysis of Covariance, Pearson correlations and linear regressions.

Results. Parents of children with ADHD reported significantly more EF challenges on the BRIEF-2 compared to the TDC group, F (5,43) = 20.89, p <.001, partial eta square =.71). No significant group difference was observed on the Working Memory (F (2, 46) = 1.38, p =.26, partial eta squared = .06) or on the Response Inhibition task (F (4, 39) = 2.48, p =.06, partial eta squared = .20) performance between the ADHD and TDC groups. Similarly, the results showed no significant group differences in the volumes of the right and left caudate and putamen, F (4,41) = .79, p >.05, partial eta square =.07). However, negative correlations were observed between right caudate volume and parent ratings of emotion regulation (r = -.51, p =.010) in the ADHD group. Linear Regression model suggested that 26.3% of the variance in emotion regulation in the ADHD group was accounted for by the right caudate volume.

Discussion. Our study showed significant EF difficulties based on parent ratings but not on performance-based tasks. No volumetric difference was observed in the caudate or the putamen between children with ADHD and the TDC group. Right caudate was related to parent ratings of EF in pediatric ADHD participants indicating the possibility of a brain-behaviour relation. These findings have implications for future treatment options in the identified subgroup of children with ADHD.

description: Amyloid-beta protein (Abeta) plays a key role in Alzheimer disease (AD) and is also implicated in cerebral small vessel disease. Serum total homocysteine (tHcy) is a risk factor for small vessel disease and cognitive impairment and correlates with plasma Abeta levels. To determine whether this association results from a common pathophysiologic mechanism, we investigated whether vitamin supplementation-induced reduction of tHcy influences plasma Abeta levels in the Vitamin Intervention in Stroke Prevention (VISP) study. Two groups of 150 patients treated with either the high-dose or low-dose formulation of pyridoxine, cobalamin, and folic acid in a randomized, double-blind fashion were selected among the participants in the VISP study without recurrent stroke during follow-up and in the highest 10% of the distribution for baseline tHcy levels. Concentrations of plasma Abeta with 40 (Abeta40) and 42 (Abeta42) amino acids were measured at baseline and at the 2-year visit. tHcy levels significantly decreased with vitamin supplementation in both groups. tHcy were strongly correlated with Abeta40 but not Abeta42 concentrations. There was no difference in the change in Abeta40, Abeta42 (p = 0.40, p = 0.35), or the Abeta42/Abeta40 ratio over time (p = 0.86) between treatment groups. Abeta measures were not associated with cognitive change. This double-blind randomized controlled trial of vitamin therapy demonstrates a strong correlation between serum tHcy and plasma Abeta40 concentrations in subjects with ischemic stroke. Treatment with high dose vitamins does not, however, influence plasma levels of Abeta, despite their effect on lowering tHcy. Our results suggest that although tHcy is associated with plasma Abeta40, they may be regulated by independent mechanisms.
