description: Paleobiologists have long sought to explain how alternative modes of speciation, including budding and bifurcating cladogenesis, shape patterns of evolution. Methods introduced over the past decade have paved the way for a renewed enthusiasm for exploring modes of speciation in the fossil record. However, the field does not yet have a strong intuition for how ancestor-descendant relationships, especially those that arise from budding speciation, might influence the shape of trees reconstructed for fossil or living clades. We developed a simulation approach based on classic paleobiological theory to ask what proportion of ancestral nodes in paleontological phylogenies are expected to correspond to sampled lineages under a range of preservational regimes. We compared our simulated results to empirical estimates of absolute fossil record completeness gathered from the literature and found that many fossilized clades of marine invertebrates are likely to display upwards of 80% sampled ancestors. Under a primarily budding model, phylogenies where 100% of the internal nodes correspond to named species are very possible for well-sampled clades at local and regional scales. We also leveraged our simulation approach to ask how budding might shape extant clades. We found that the ancestral signature of budding causes rampant hard polytomies in extant clades. Our results highlight how budding can yield dramatic and unrecognized effects on phylogenetic reconstruction of clades of both living and extinct organisms.

Supersymmetry and Positive Energy in Classical and Quantum Two-Dimensional Dilaton Gravity

Year: 1992
Subjects: subject: High Energy Physics - Theory (hep-th)

description: An $N = 1$ supersymmetric version of two dimensional dilaton gravity coupled to matter is considered. It is shown that the linear dilaton vacuum spontaneously breaks half the supersymmetries, leaving broken a linear combination of left and right supersymmetries which squares to time translations. Supersymmetry suggests a spinorial expression for the ADM energy $M$, as found by Witten in four-dimensional general relativity. Using this expression it is proven that ${M}$ is non-negative for smooth initial data asymptotic (in both directions) to the linear dilaton vacuum, provided that the (not necessarily supersymmetric) matter stress tensor obeys the dominant energy condition. A {\it quantum} positive energy theorem is also proven for the semiclassical large-$N$ equations, despite the indefiniteness of the quantum stress tensor. For black hole spacetimes, it is shown that $M$ is bounded from below by $e^{- 2 ϕ_H}$, where $ϕ_H$ is the value of the dilaton at the apparent horizon, provided only that the stress tensor is positive outside the apparent horizon. This is the two-dimensional analogue of an unproven conjecture due to Penrose. Finally, supersymmetry is used to prove positive energy theorems for a large class of generalizations of dilaton gravity which arise in consideration of the quantum theory.

description: Effective use of Machine Learning to support extracting maximal information from limited sensor data is one of the important research challenges in robotic sensing. This thesis develops techniques for detecting and characterizing patterns in noisy sensor data. Our Bayesian Aggregation (BA) algorithmic framework can leverage data fusion from multiple low Signal-To-Noise Ratio (SNR) sensor observations to boost the capability to detect and characterize the properties of a signal generating source or process of interest. We illustrate our research with application to the nuclear threat detection domain. Developed algorithms are applied to the problem of processing the large amounts of gamma ray spectroscopy data that can be produced in real-time by mobile radiation sensors. The thesis experimentally shows BA’s capability to boost sensor performance in detecting radiation sources of interest, even if the source is faint, partiallyoccluded, or enveloped in the noisy and variable radiation background characteristic of urban scenes. In addition, BA provides simultaneous inference of source parameters such as the source intensity or source type while detecting it. The thesis demonstrates this capability and also develops techniques to efficiently optimize these parameters over large possible setting spaces. Methods developed in this thesis are demonstrated both in simulation and in a radiation-sensing backpack that applies robotic localization techniques to enable indoor surveillance of radiation sources. The thesis further improves the BA algorithm’s capability to be robust under various detection scenarios. First, we augment BA with appropriate statistical models to improve estimation of signal components in low photon count detection, where the sensor may receive limited photon counts from either source and/or background. Second, we develop methods for online sensor reliability monitoring to create algorithms that are resilient to possible sensor faults in a data pipeline containing one or multiple sensors. Finally, we develop Retrospective BA, a variant of BA that allows reinterpretation of past sensor data in light of new information about percepts. These Retrospective capabilities include the use of Hidden Markov Models in BA to allow automatic correction of a sensor pipeline when sensor malfunction may be occur, an Anomaly- Match search strategy to efficiently optimize source hypotheses, and prototyping of a Multi-Modal Augmented PCA to more flexibly model background and nuisance source fluctuations in a dynamic environment.

description: We present a collection of methods to simulate entangled dynamics of open quantum systems governed by the Lindblad equation with tensor network methods. Tensor network methods using matrix product states have been proven very useful to simulate many-body quantum systems and have driven many innovations in research. Since the matrix product state design is tailored for closed one-dimensional systems governed by the Schrödinger equation, the next step for many-body quantum dynamics is the simulation of open quantum systems. We review the three dominant approaches to the simulation of open quantum systems via the Lindblad master equation: quantum trajectories, matrix product density operators, and locally purified tensor networks. Selected examples guide possible applications of the methods and serve moreover as a benchmark between the techniques. These examples include the finite temperature states of the transverse quantum Ising model, the dynamics of an exciton traveling under the influence of spontaneous emission and dephasing, and a double-well potential simulated with the Bose-Hubbard model including dephasing. We analyze which approach is favorable leading to the conclusion that a complete set of all three methods is most beneficial, push- ing the limits of different scenarios. The convergence studies using analytical results for macroscopic variables and exact diagonalization methods as comparison, show, for example, that matrix product density operators are favorable for the exciton problem in our study. All three methods access the same library, i.e., the software package Open Source Matrix Product States, allowing us to have a meaningful comparison between the approaches based on the selected examples. For example, tensor operations are accessed from the same subroutines and with the same optimization eliminating one possible bias in a comparison of such numerical methods.

This policy brief analyses data collected in Ghana shortly after vaccines were delivered in early March 2021, and is the second survey from this study – the first wave was conducted in August 2020 prior to any COVID-19 vaccines being approved and available.
We conducted a nationally representative online survey in Ghana (N = 1,558) throughout March 2021 after the first batches of Oxford AstraZeneca vaccines had arrived in Ghana through the COVAX initiative.
In our analyses, we operationalised vaccine hesitancy as respondents who answered ‘no’ and ‘I don’t know’ to the question: “When a COVID-19 vaccine becomes available to you, would you like to get vaccinated?” We hope that our findings provide rich and interesting insights into the socioeconomic and psychological factors associated with COVID-19 vaccine hesitancy in Ghana.

description: We study the following problem: Given initial data on a compact Cauchy horizon, does there exist a unique solution to wave equations on the globally hyperbolic region? Our main results apply to any spacetime satisfying the null energy condition and containing a compact Cauchy horizon with surface gravity that can be normalised to a non-zero constant. Examples include the Misner spacetime and the Taub-NUT spacetime. We prove an energy estimate close to the Cauchy horizon for wave equations acting on sections of vector bundles. Using this estimate we prove that if a linear wave equation can be solved up to any order at the Cauchy horizon, then there exists a unique solution on the globally hyperbolic region. As a consequence, we prove several existence and uniqueness results for linear and non-linear wave equations without assuming analyticity or symmetry of the spacetime and without assuming that the generators close. We overcome in particular the essential remaining difficulty in proving that vacuum spacetimes with a compact Cauchy horizon with constant non-zero surface gravity necessarily admits a Killing vector field. This work is therefore related to the strong cosmic censorship conjecture.

EVLA Observations of OH Masers in ON 1

Subjects: subject: Astrophysics (astro-ph)

description: This Letter reports on initial Expanded Very Large Array (EVLA) observations of the 6035 MHz masers in ON 1. The EVLA data are of good quality, lending confidence in the new receiver system. Nineteen maser features, including six Zeeman pairs, are detected. The overall distribution of 6035 MHz OH masers is similar to that of the 1665 MHz OH masers. The spatial resolution is sufficient to unambiguously determine that the magnetic field is strong (~ -10 mG) at the location of the blueshifted masers in the north, consistent with Zeeman splitting detected in 13441 MHz OH masers in the same velocity range. Left and right circularly polarized ground-state features dominate in different regions in the north of the source, which may be due to a combination of magnetic field and velocity gradients. The combined distribution of all OH masers toward the south is suggestive of a shock structure of the sort previously seen in W3(OH).

description: We investigate linear and non-linear transport in a double quantum dot system weakly coupled to spin-polarized leads. In the linear regime, the conductance as well as the non-equilibrium spin accumulation are evaluated in analytic form. The conductance as a function of the gate voltage exhibits four peaks of different height, with mirror symmetry with respect to the charge neutrality point. As the polarization angle is varied, the position and shape of the peaks changes in a characteristic way which preserves the electron-hole symmetry of the problem. In the nonlinear regime negative differential conductance features occur for non collinear magnetisations of the leads. In the considered sequential tunneling limit, the tunneling magneto resistance (TMR) is always positive with a characteristic gate voltage dependence for non-collinear magnetization. If a magnetic field is added to the system, the TMR can become negative.

description: From the standard procedure for constructing Feynman vacuum graphs in $ϕ^4$ theory from the generating functional $Z$, we find a relation with sets of certain combinatorial matrices, which allows us to generate the set of all Feynman graphs and the respective multiplicities in an equivalent combinatoric way. These combinatorial matrices are explicitly related with the permutation group, which facilitates the construction of the vacuum Feynman graphs. Various insights in this combinatoric problem are proposed, which in principle provide an efficient way to compute the Feynman vacuum graphs and its multiplicities.

description: Injuries to the lateral ankle ligaments can result in ankle instability problems. Limited data exists in relation to isokinetic and isometric strength measures of the ankle, with an absence of data in relation to isotonic power measures. Therefore, the purpose of this study is to identify if there is a difference between subjects with unstable ankles and subjects with stable ankles with respect to isokinetic ankle strength, isometric ankle strength, and isotonic ankle power. Eighteen subjects with ankle instability (age, 23.9 ± 2.81 years; height 170.4 ± 8.9 cm; mass 73 ± 18.9 kg) and eighteen subjects with healthy ankles (age, 22.4 ± 1.04 years; height 170.9 ± 8.4 cm; mass 71 ± 13 kg) participated in the study. Classification of ankle instability was attained through the use of the Cumberland Ankle Instability Tool. Inversion, eversion, plantar flexion, and dorsiflexion motions about the ankle were analyzed, with peak torque values obtained through isometric and concentric-eccentric isokinetic movements, and peak power values collected for isotonic movements. The average of the trials for each direction was standardized to each subject's body mass and utilized for statistical analysis. No significant differences were displayed between groups for isometric ankle strength, isokinetic ankle strength and isotonic ankle power. No strength deficits were identified between unstable and stable ankles; therefore strength is most likely not related to ankle instability.
The star formation histories of early-type galaxies: insights from the rest-frame ultra-violet
Creators: name: Kaviraj, S.
Publisher: name: arXiv
Year: 2007
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Our current understanding of the star formation histories of early-type galaxies is reviewed, in the context of recent observational studies of their ultra-violet (UV) properties. Combination of UV and optical spectro-photometric data indicates that the bulk of the stellar mass in the early-type population forms at high redshift (z > 2), typically over short timescales (< 1 Gyr). Nevertheless, early-types of all luminosities form stars over the lifetime of the Universe, with most luminous (-23 < M(V) < -21) systems forming 10-15% of their stellar mass after z = 1 (with a scatter to higher value), while their less luminous (M(V) > -21) counterparts form 30-60% of their mass in the same redshift range. The large scatter in the (rest-frame) UV colours in the redshift range 0 < z < 0.7 indicates widespread low-level star formation in the early-type population over the last 8 billion years. The mass fraction of young (< 1 Gyr old) stars in luminous early-type galaxies varies between 1% and 6% at z~0 and is in the range 5-13% at z~0.7. The intensity of recent star formation and the bulk of the UV colour distribution is consistent with what might be expected from minor mergers (mass ratios < 1:6) in an LCDM cosmology.

description: We study an extended Skyrme model which includes fourth and sixth-order terms. We explore some static properties like the $Δ$-nucleon mass splitting and investigate the Skyrmion breathing mode in the framework of the linear response theory. We find that the monopole response function has a pronounced peak located at $\sim$ 400 MeV, which we identify to the Roper resonance $N(1440)$. As compared to the standard one, the extended Skyrme model provides a more accurate description of baryon properties.

Two Circular-Rotational Eigenmodes in Vortex Gyrotropic Motions in Soft Magnetic Nanodots

description: We found, by micromagnetic numerical and analytical calculations, that the clockwise (CW) and counterclockwise (CCW) circular-rotational motions of a magnetic vortex core in a soft magnetic circular nanodot are the elementary eigenmodes existing in the gyrotropic motion with respect to the corresponding CW and CCW circular-rotational-field eigenbasis. Any steady-state vortex gyrotropic motions driven by a linearly polarized oscillating in-plane magnetic field in the linear regime can be perfectly understood according to the superposition of the two circular eigenmodes, which show asymmetric resonance characteristics reflecting the vortex polarization. The relative magnitudes in the amplitude and phase between the CCW and CW eigenmodes determine the elongation and orientation of the orbital trajectories of the vortex core motions, respectively, which trajectories vary with the polarization and chirality of the given vortex as well as the field frequency across the resonance frequency.

subject: FOS: Economics and business

description: In this dissertation, I investigate how and when close relationships interfere with obligations to remain objective in the workplace. By adopting a psychological point of view, I suggest that breakdowns in objectivity can be explained by a mechanism known as “psychological closeness”—that is, feeling attached and connected to another person or people. I build upon this argument by suggesting that certain individuals are less susceptible to the negative effects of psychological closeness than others. Specifically, I argue that people who do not define themselves in terms of their close relationships—otherwise known as low “relational-interdependent self-construal (RSC)”—are least vulnerable to objectivity failures that help psychologically close others. I investigated the relation among RSC, psychological closeness, and failures to remain objective across four experimental studies. In Study 1, I tested whether psychological closeness to another person influenced objectivity failures using a laboratory experiment in which interactions between individuals who knew each other well (i.e., were psychologically close) were compared to interactions between individuals who did not know each other well (i.e., were not psychologically close). In Study 2, I examined whether induced psychological closeness to another person predicted objectivity failures. In addition, I tested whether this relationship was moderated by RSC. In Studies 3 and 4, I continued to test the theoretical model using online experiments. In Study 4, I also tested whether temporarily reduced RSC led to fewer objectivity failures to help psychologically close others. Overall, the results from these studies support the hypothesized relationship between psychological closeness and objectivity failures. Interestingly, an unexpected pattern of results emerged for RSC, suggesting that this trait is more influential in determining how individuals treat psychologically distant (vs. close) others. Together these studies offer new insights about how close relationships and RSC interact to influence ethical decision making in the workplace.

description: In recent years, autonomous driving has become an increasingly practical technology. With state-of-the-art computer and sensor engineering, autonomous vehicles may be produced and widely used for travel and logistics in the near future. They have great potential to reduce traffic accidents, improve transportation efficiency, and release people from driving tasks while commuting. Researchers have built autonomous vehicles that can drive on public roads and handle normal surrounding traffic and obstacles. However, in situations like lane changing and merging, the autonomous vehicle faces the challenge of performing smooth interaction with human-driven vehicles. To do this, autonomous vehicle intelligence still needs to be improved so that it can better understand and react to other human drivers on the road. In this thesis, we argue for the importance of implementing ”socially cooperative driving”, which is an integral part of everyday human driving, in autonomous vehicles. An intention-integrated Prediction- and Cost function-Based algorithm (iPCB) framework is proposed to enable an autonomous vehicles to perform cooperative social behaviors. We also propose a behavioral planning framework to enable the socially cooperative behaviors with the iPCB algorithm. The new architecture is implemented in an autonomous vehicle and can coordinate the existing Adaptive Cruise Control (ACC) and Lane Centering interface to perform socially cooperative behaviors. The algorithm has been tested in over 500 entrance ramp and lane change scenarios on public roads in multiple cities in the US and over 10; 000 in simulated case and statistical testing. Results show that the proposed algorithm and framework for autonomous vehicle improves the performance of autonomous lane change and entrance ramp handling. Compared with rule-based algorithms that were previously developed on an autonomous vehicle for these scenarios, over 95% of potentially unsafe situations are avoided.

description: Let $G$ be a group acting properly by isometries and with a strongly contracting element on a geodesic metric space. Let $N$ be an infinite normal subgroup of $G$, and let $δ_N$ and $δ_G$ be the growth rates of $N$ and $G$ with respect to the pseudo-metric induced by the action. We prove that if $G$ has purely exponential growth with respect to the pseudo-metric then $δ_N/δ_G>1/2$. Our result applies to suitable actions of hyperbolic groups, right-angled Artin groups and other CAT(0) groups, mapping class groups, snowflake groups, small cancellation groups, etc. This extends Grigorchuk's original result on free groups with respect to a word metrics and a recent result of Jaerisch, Matsuzaki, and Yabuki on groups acting on hyperbolic spaces to a much wider class of groups acting on spaces that are not necessarily hyperbolic.

description: According to the Schiff theorem an external electric field vanishes at atomic nucleus in a neutral atom, i.e. it is completely shielded by electrons. This makes a nuclear electric dipole moment (EDM) unobservable. In this paper an extension of the Schiff theorem to an oscillating electric field is considered. Such field can reach the nucleus and interact with the nuclear EDM. The enhancement effect appears if the field is in resonance with atomic or molecular transition. The shielding by electrons strongly affects low-energy nuclear electric dipole transition amplitudes in different nuclear reactions including radiative transitions, radiative nucleon capture, photo or electro-excitation of nuclei and laser-induced or laser-enhanced nuclear reactions.
Autonomous Animation of Humanoid Robots

Year: 2016
Subjects: subject: Mechanical Engineering
subject: FOS: Mechanical engineering

description: Gestures and other body movements of humanoid robots can be used to convey meanings which are extracted from an input signal, such as speech or music. For example, the humanoid robot waves its arm to say goodbye or nods its head to dance to the beats of the music. This thesis investigates how to autonomously animate a real humanoid robot given an input signal. This thesis addresses five core challenges, namely: Representation of motions, Mappings between meanings and motions, Selection of relevant motions, Synchronization of motion sequences to the input signal, and Stability of the motion sequences (R-M-S3). We define parameterized motions that allow a large variation of whole body motions to be generated from a small core motion library and synchronization of the motions to different input signals. To assign meanings to motions, we represent meanings using labels and map motions to labels autonomously using motion features. We also examine different metrics to determine similar motions so that a new motion is mapped to existing labels of the most similar motion. We explain how we select relevant motions using labels, synchronize the motion sequence to the input signal, and consider the audience’s preferences. We contribute an algorithm that determines the stability of a motion sequence. We also define the term relative stability, where the stability of one motion sequence is compared to other motion sequences. We contribute an algorithm to determine the most stable motion sequence so that the humanoid robot animates continuously without interruptions. We demonstrate our work with two input signals – music and speech, where a humanoid robot autonomously dances to any piece of music using the beats and emotions of the music and also autonomously gestures according to its speech. We describe how we use our solutions to R-M-S3, and present a complete algorithm that captures the meanings of the input signal and weighs the selection of the best sequence using two criteria: audience feedback and stability. Our approach and algorithms are general to autonomously animate humanoid robots, and we use a real NAO humanoid robot and in simulation as an example.

Complex stories spaghetti into branches, side stories, and intertwining narratives; search engines, our most popular navigational tools, are limited in their capacity to explore such complex stories. We propose a methodology for creating structured summaries of information, which we call metro maps. Our proposed algorithm generates a concise structured set of documents that maximizes coverage of salient pieces of information. Most importantly, metro maps explicitly show the relations among retrieved pieces in a way that captures story development. The overarching theme of this work is formalizing characteristics of good maps, and providing efficient algorithms (with theoretical guarantees) to optimize them. Moreover, as information needs vary from person to person, we integrate user interaction into our framework, allowing users to alter the maps to better reflect their interests. Pilot user studies with real-world datasets demonstrate that the method is able to produce maps which help users acquire knowledge efficiently. We believe that metro maps could be powerful tools for any Web user, scientist, or intelligence analyst trying to process large amounts of data.

description: This thesis describes an approach to create high-quality music synthesis by automatically constructing an instrument model and a performance model; the latter module generates control signals from score input and drives the former module to produce synthetic instrumental sounds. By designing and applying appropriate machine learning techniques as well as domain knowledge, the instrument model and the performance model are constructed from acoustic examples and their corresponding scores for a musical instrument. The automated model is able to synthesize realistic instrumental performances from scores.

description: The unique binary AR Scorpii consists of an asynchronously rotating, magnetized white dwarf (WD) that interacts with its red-dwarf companion to produce a large-amplitude, highly coherent pulsation every 1.97 minutes. Over the course of two years, we obtained thirty-nine hours of time-resolved, optical photometry of AR Sco at a typical cadence of 5 seconds to study this pulsation. We find that it undergoes significant changes across the binary orbital period and that its amplitude, phase, and waveform all vary as a function of orbital phase. We show that these variations can be explained by constructive and destructive interference between two periodic, double-peaked signals: the spin-orbit beat pulse, and a weaker WD spin pulse. Modelling of the light curve indicates that in the optical, the amplitude of the primary spin pulse is 50% of the primary beat amplitude, while the secondary maxima of the beat and spin pulses have similar amplitudes. Finally, we use our timings of the beat pulses to confirm the presence of the disputed spin-down of the WD. We measure a beat-frequency derivative of -5.14(32) x 10^-17 Hz/s and show that this is attributable to the spin-down of the WD. This value is approximately twice as large as the estimate from Marsh et al. (2016) but is nevertheless consistent with the constraints established in Potter & Buckley (2018). Our precise measurement of the spin-down rate confirms that the decaying rotational energy of the magnetized white dwarf is sufficient to power the excess electromagnetic radiation emitted by the binary.

description: We study containment and uniqueness problems concerning matrix convex sets. First, to what extent is a matrix convex set determined by its first level? Our results in this direction quantify the disparity between two product operations, namely the product of the smallest matrix convex sets over $K_i \subseteq \mathbb{C}^d$, and the smallest matrix convex set over the product of $K_i$. Second, if a matrix convex set is given as the matrix range of an operator tuple $T$, when is $T$ determined uniquely? We provide counterexamples to results in the literature, showing that a compact tuple meeting a minimality condition need not be determined uniquely, even if its matrix range is a particularly friendly set. Finally, our results may be used to improve dilation scales, such as the norm bound on the dilation of (non self-adjoint) contractions to commuting normal operators, both concretely and abstractly.

Talking Translation: An Interview with Lawrence Hill
Creators: name: Lappin-Fortin, Kerry
Publisher: name: Canadian Literature
Year: 2015

description: This interview with Canadian writer Lawrence Hill addresses some of the difficulties faced by translators of his work, particularly when attempting to render period dialogue and Black idiom as authentically as possible. Much of the discussion focuses on his novel A Book of Negroes (also published under the title Someone Knows my Name, and, in French, as Aminata). The author is asked to reflect on what is lost−and gained−in translation.

description: We present a simple method for producing a low-drift atomic frequency reference based upon the Zeeman effect. Our Zeeman Shifted Atomic Reference `ZSAR' is demonstrated to have tens of GHz tuning range, limited only by the strength of the applied field. ZSAR uses Doppler-free laser spectroscopy in a thermal vapor where the vapor is situated in a large, static and controllable magnetic field. We use a heated $^{85}$Rb vapor cell between a pair of position-adjustable permanent magnets capable of applying magnetic fields up to 1 T. To demonstrate the frequency reference we use a spectral feature from the Zeeman shifted D1 line in $^{85}$Rb at 795 nm to stabilize a laser to the 7S$_{1/2}$ $\longrightarrow$ 23P$_{1/2}$ transition in atomic cesium, which is detuned by approximately 19 GHz from the unperturbed Rb transition. We place an upper bound on the stability of the technique by measuring a 2.5 MHz RMS frequency difference between the two spectral features over a 24 hour period. This versatile method could be adapted easily for use with other atomic species and the tuning range readily increased by applying larger magnetic fields.

From the Dark Territories of Pain and Exclusion to Bright Futures? An Analysis of Rawi Hage's Cockroach
Creators: name: Marchi, Lisa
Publisher: name: Canadian Literature
Year: 2015

description: Combining feminist, queer, and postcolonial perspectives, the proposed article analyzes and critically interrogates Cockroach by Arab-Quebecois writer Rawi Hage, focusing in particular on the writer’s orientation toward the past and his fascination with dark themes relating to destitution, abjection, delinquency, unhappiness, and violence. It relies on recent feminist and particularly queer cultural studies theoretical elaborations that have explored the potential of backward trajectories and dark affects to envision bright futures (Halberstam, 2011; Brooks, 2006; Love, 2007; Ahmed, 2010). In particular, the essay analyzes the ways in which Hage intersects past traumatic experiences of war and violence with more recent forms of racial discrimination and oppression, to show that Cockroach draws a continuum across temporal and geographical borders. It argues that by venturing into the dark territories of violence and abjection, Hage disturbs what we normally perceive as familiar, and powerfully reveals what usually remains unseen within our multicultural democracies: the contradictions, limits, and failures of the assumption of happiness (Ahmed, 2010). Finally, it claims that by observing Canadian multiculturalism from the vantage point of his ‘wretched’ character, we suddenly realize that happiness may also be a bad, “ugly” feeling (Ngai, 2007), particularly when it is imposed by power in an attempt to hide the asymmetries, injustices, and discriminations that still persist in today’s democracies.
