description: This thesis examines the role of an art workshop in releasing Indigenous youth’s creativity and connecting them to school in a culturally appropriate way. My research questions consider how cultural and artistic engagement address student wellness and educational engagement in order to consider how pedagogy and curriculum can be adapted to better serve Blackfoot students. Following research conversations with school personnel, Storywork analysis was used to explore the importance of art-as-therapy, self-representation, art as a voice, traditional examples of art in culture, and contemporary Indigenous art politics. This study found that art connected youth to their culture, their peers and their school. Art was also described as a method for rediscovering voice, empowering students, and developing a positive identity. The findings are intended to support schools’ capacities to respond to Indigenous student wellness and educational needs. Findings will support a larger initiative that seeks to articulate a framework that other Indigenous communities and schools may draw upon.

description: We study the electrodynamics of a kinetically mixed dark photon cloud that forms through superradiance around a spinning black hole, and design strategies to search for the resulting multimessenger signals. A dark photon superradiance cloud sources a rotating dark electromagnetic field which, through kinetic mixing, induces a rotating visible electromagnetic field. Standard model charged particles entering this field initiate a transient phase of particle production that populates a plasma inside the cloud and leads to a system which shares qualitative features with a pulsar magnetosphere. We study the electrodynamics of the dark photon cloud with resistive magnetohydrodynamics methods applicable to highly magnetized plasma, adapting techniques from simulations of pulsar magnetospheres. We identify turbulent magnetic field reconnection as the main source of dissipation and electromagnetic emission, and compute the peak luminosity from clouds around solar-mass black holes to be as large as $10^{43}$ erg/s for open dark photon parameter space. The emission is expected to have a significant X-ray component and is potentially periodic, with period set by the dark photon mass. The luminosity is comparable to the brightest X-ray sources in the Universe, allowing for searches at distances of up to hundreds of Mpc with existing telescopes. We discuss observational strategies, including targeted electromagnetic follow-ups of solar-mass black hole mergers and targeted continuous gravitational wave searches of anomalous pulsars.

The Russian Orthodox Church on Human Rights

Publisher: name: Columbia University
Year: 2010
Subjects: Religion

description: The Russian Church in its official teaching on human dignity, freedom, and rights has recently proposed that human rights “cannot be superior to the values of the spiritual world. Thus, “It is inadmissible and dangerous to interpret human rights as the ultimate and universal foundation of societal life to which religious views and practice should be subjected. Human rights should not subjugate any religious values and norms, but be subject to them. Thus, human rights are denied a status of the ultimate authority and are given a subordinate status in the social contract of the Russian Church.
What is designated as human rights? Do human rights have a reasonable degree of actuality?

Celling SHIM: Compiling Deterministic Concurrency to a Heterogeneous Multicore
Creators: name: Vasudevan, Nalini

Publisher: name: Columbia University
Year: 2009
Subjects: Computer science

description: Parallel architectures are the way of the future, but are notoriously difficult to program. In addition to the low-level constructs they often present (e.g., locks, DMA, and non-sequential memory models), most parallel programming environments admit data races: the environment may make nondeterministic scheduling choices that can change the function of the program. We believe the solution is model-based design, where the programmer is presented with a constrained higher-level language that prevents certain unwanted behavior. In this paper, we describe a compiler for the SHIM scheduling-independent concurrent language that generates code for the Cell Broadband heterogeneous multicore processor. The complexity of the code our compiler generates relative to the source illustrates how difficult it is to manually write code for the Cell. We demonstrate the efficacy of our compiler on two examples. While the SHIM language is (by design) not ideal for every algorithm, it works well for certain applications and simplifies the parallel programming process, especially on the Cell architecture.
Interaction between spin and Abrikosov vortices in doped topological insulators

description: In the topological superconductor with the nematic superconductivity in $E_u$ representation, it is possible to have different types of vortices. One is associated with the vorticity in the particle-hole space and corresponds to the Abrikosov vortex. Another type corresponds to the vorticity in the spin space and is called spin vortex. We study the interaction of the Abrikosov vortex with the spin vortices. We derive the free energy of the sample with the Abrikosov and the strain-induced spin vortices using the Ginzburg-Landau approach for the two-component superconducting order parameter. We calculate the critical strain at which the spin vortex is formed. We show that the spin vortex and the Abrikosov vortex attract to each other and, as a result, they have a common core. We show that there are no zero-energy states (Majorana fermions) localized near the common vortex core of the Abrikosov vortex and the spin vortex of any type. Possible experimental realization is discussed.
A preliminary evaluation of the results-based Forest and Range Practices Act : fostering innovation in forest practices?
Creators: name: Malkinson, Leah
Publisher: name: University of British Columbia
Year: 2011

description: In 2004 the British Columbia (BC) government introduced the Forest and Range Practices Act (FRPA) and described it as a ‘results-based’ approach to forest management. This research sought to evaluate the potential effectiveness of the FRPA regime in achieving one of its stated goals - ‘to foster the development of innovative forest practices and provide professional freedom to manage in the delivery of defined results’ (BC, 2004). Research methods included a review of the first 65 Forest Stewardship Plans (FSP’s) approved under FRPA to identify the potential for innovation indicated by practice commitments for three key environmental values – soils, biodiversity and riparian areas. A web survey and phone interviews with the prescribing foresters who developed these plans helped to build an understanding of the factors influencing their willingness to innovate under FRPA with respect to practices designed to manage for these three values. This thesis describes how the FRPA framework is not purely performance-based, but is rather a complex mixture of regulatory approaches. It includes the application of a ‘default practice’ approach for most environmental values that licensees may choose to implement or to propose alternative practices for approval. Early FSP’s indicated limited potential for innovation with only 10% of forest practice commitments reflecting approaches that were alternative to the default practices. These alternative forest practices are often better characterized as providing increased flexibility in the application of a default practice, rather than being truly new and innovative. Key reasons for this response include a perception by prescribing foresters that the default forest practices are reasonably effective, leaving little incentive to identify alternatives, and the overriding importance of receiving approval for their first FSP’s within the requisite timelines. The development of alternative forest practices was perceived as potentially time consuming and costly, and could put at risk the certainty of government approval for their FSP, and reasons for this perception are discussed. Further research to evaluate the actual degree of innovation reflected in practices on the ground, as well as the suggested likelihood of increasing innovation in practices over time is recommended.

description: Volumetric, multimodal imaging with precise spatial and temporal co-registration can provide valuable and complementary information for diagnosis and monitoring. Considerable research has sought to combine 3D photoacoustic (PA) and ultrasound (US) imaging in clinically translatable configurations. However, technical compromises currently result in poor image quality either for photoacoustic or ultrasonic modes. This work aims to provide translatable, high quality, simultaneously co-registered dual-mode PA/US 3D tomography. Volumetric imaging based on a synthetic aperture approach was implemented by interlacing PA and US acquisitions during a rotate-translate scan with a 5-MHz linear array (12 angles and 30-mm translation to image a 21-mm diameter, 19 mm long cylindrical volume within 21 seconds). For co-registration, an original calibration method using a specifically designed thread phantom was developed to estimate 6 geometrical parameters and 1 temporal off-set through global optimization of the reconstructed sharpness and superposition of calibration phantom structures. Phantom design and cost function metrics were selected based on analysis of a numerical phantom, and resulted in a high estimation accuracy for the 7 parameters. Experimental estimations validated the calibration repeatability. The estimated parameters were used for bimodal reconstruction of additional phantoms with either identical or distinct spatial distributions of US and PA contrasts. Superposition distance of the two modes was within < 10% of the acoustic wavelength and a wavelength-order uniform spatial resolution was obtained. This dual-mode PA/US tomography should contribute to more sensitive and robust detection and follow-up of biological changes or the monitoring slower-kinetic phenomena in living systems such as the accumulation of nanoagents.

Topology and emergent symmetries in dense compact star matter

description: It has been found that the topology effect and the possible emergent scale and hidden local flavor symmetries at high density reveal a novel structure of the compact star matter. The $N_f\geq2$ baryons can be described by the skyrmion in the large $N_c$ limit and there is a robust topology change in the skyrmion matter approach to dense nuclear matter. The hidden scale and local flavor symmetries which are sources introducing the lightest scalar meson -- dilaton -- and lowest lying vector mesons into to nonlinear chiral effective theory are seen to play important roles in understanding the nuclear force. We review in this paper the generalized nuclear effective theory (G$n$EFT), which applicable to nuclear matter from low density to the compact star density, constructed with the robust conclusion from the topology approach to dense matter and emergent scale and hidden local flavor symmetries. The topology change at density larger than two times saturation density $n_0$ encoded in the parameters of the effective field theory is interpreted as the hadron-quark continuity in the sense of Cheshire Cat Principle. A novel feature predicted in this theory that has not been found before is the precocious appearance of the conformal sound velocity in the cores of massive stars, although the trace of the energy-momentum tensor of the system is not zero. That is, in contrast to the usual picture, the cores of massive stars are composed of quasiparticles of fractional baryon charges, neither baryons nor deconfined quarks. Hidden scale and local flavor symmetries emerge and give rise a resolution of the longstanding $g_A$ quench problem in nuclei transition. To illustrate the rationality of the GnEFT, we finally confront the generalized effective field theory to the global properties of neutron star and the data from gravitational wave detections.

description: Web Applications (WA's) failures may lead to collapse of the institutions, therefore the importance of good quality WA's is increasing over the time. Testing is one of the best quality metrics that decide whether WA's are reliable or not. WA's testing approaches suffer from the lack of proper coverage of WA's functional requirements testing. On the other hand some approaches produce test cases that already cover WA's testing but they also produce a great number of irrelevant test cases. This research analyzed the main testing approaches for WA's and GUI applications. Also we have an overview of Test-Driven Development and its effects on the current development. The specification of good testing approach that satisfies the proper testing is then presented.

Compensation Benchmarking, Leapfrogs, and the Surge in Executive Pay

description: Scholars frequently argue whether the sharp rise in chief executive officer (CEO) pay in recent years is "efficient" or is a consequence of "rent extraction" because of the failure of corporate governance in individual firms. This article argues that governance failure must be conceptualized at the market rather than the firm level because excessive pay increases for even relatively few CEOs a year spread to other firms through the cognitively and rhetorically constructed compensation networks of "peer groups," which are used in the benchmarking process to negotiate the compensation of CEOs. Counterfactual simulation based on Standard and Poor's ExecuComp data demonstrates that the effects of CEO "leapfrogging" potentially explain a considerable fraction of the overall upward movement of executive compensation since the early 1990s.

description: For Romney to appeal to voters, he needs to distance himself from the far right and show the electorate that he will not be beholden to the extremists who are so visible within the Republican Party. In short, Romney needs to have his Sistah Souljah moment. Twenty years ago, Bill Clinton, then a conservative southern governor on his way to the nomination, further demonstrated his centrist credentials by criticizing controversial African American rapper Sistah Souljah. Expressing a similar statement about the Tea Party, Rush Limbaugh, the Birthers or some other visible right wing figure or group would help Romney accomplish the same thing.

description: We study the equilibrium and non-equilibrium properties of topological dipolar intersurface exciton condensates within time-reversal invariant topological insulators in three spatial dimensions without a magnetic field. We elucidate that, in order to correctly identify the proper pairing symmetry within the condensate order parameter, the full three-dimensional Hamiltonian must be considered. As a corollary, we demonstrate that only particles with similar chirality play a significant role in condensate formation. Furthermore, we find that the intersurface exciton condensation is not suppressed by the interconnection of surfaces in three-dimensional topological insulators as the intersurface polarizability vanishes in the condensed phase. This eliminates the surface current flow leaving only intersurface current flow through the bulk. We conclude by illustrating how the excitonic superfluidity may be identified through an examination of the terminal currents above and below the condensate critical current.

description: The XENON100 dark matter experiment uses liquid xenon (LXe) in a time projection chamber (TPC) to search for Xe nuclear recoils resulting from the scattering of dark matter Weakly Interacting Massive Particles (WIMPs). In this paper we present a detailed description of the detector design and present performance results, as established during the commissioning phase and during the first science runs. The active target of XENON100 contains 62 kg of LXe, surrounded by an LXe veto of 99 kg, both instrumented with photomultiplier tubes (PMTs) operating inside the liquid or in Xe gas. The LXe target and veto are contained in a low-radioactivity stainless steel vessel, embedded in a passive radiation shield. The experiment is installed underground at the Laboratori Nazionali del Gran Sasso (LNGS), Italy and has recently published results from a 100 live-days dark matter search. The ultimate design goal of XENON100 is to achieve a spin-independent WIMP-nucleon scattering cross section sensitivity of σ= 2x10^-45 cm^2 for a 100 GeV/c^2 WIMP.

description: Bars and spirals are among the main drivers of the secular evolution of galactic disks, and it is, thus, of prime importance to better understand their exact nature and dynamics. In this respect, the Milky Way provides a unique laboratory in which to study a snapshot of their detailed dynamical influence in six-dimensional phase-space. With the advent of present and future astrometric and spectroscopic surveys, such six-dimensional phase-space data can be obtained for stars in an increasingly large volume around the Sun. Here, we review the signatures of - and constraints on - disk non-axisymmetries obtained from recent stellar kinematical data sets, including (i) the detection of resonant moving groups in the solar neighbourhood, (ii) the non-zero value of the Oort constants C and K, and (iii) the detection of a radial velocity gradient of 4 km/s/kpc in the extended solar neighbourhood (d<2 kpc).

description: This article presents one side of an ongoing debate on the appropriateness of C-like languages as hardware description languages. The article examines various features of C and their mapping to hardware, and makes a cogent argument that vanilla C is not the right language for hardware description if synthesis is the goal. C-like languages are far more compelling for these tasks, and one in particular, SystemC, is now widely used, as are many ad hoc variants.

description: Questions regarding energy dissipation in astrophysical jets are open to date, despite of numerous attempts to limit the diversity of models. Some of the most popular models assume that energy is transferred to particles via internal shocks, which develop as a consequence of non-uniform velocity of the jet matter. In this context, we study the structure and energy deposition of colliding plasma shells, focusing our attention on the case of initially inhomogeneous shells. This leads to formation of distorted (corrugated) shock fronts -- a setup that has recently been shown to revive particle acceleration in relativistic magnetized perpendicular shocks. Our studies show that the radiative power of the far downstream of non-relativistic magnetized perpendicular shocks is moderately enhanced with respect to the flat shock cases. Based on the decay rate of downstream magnetic field, we make predictions for multiwavelength polarization properties.

Microglial Panx1 is a Spinal Determinant of Arthritis Joint Pain

description: Pain is a debilitating feature of arthritis. Despite recent advances in treating joint inflammation and the widespread use of pain medications by arthritis patients, adequate pain control is an ongoing medical problem. A major challenge is that joint pain is poorly understood: some individuals with severe joint damage report little pain, whereas paradoxically others with seemingly minor joint damage complain of debilitating pain. This thesis examines how microglia in the spinal cord signal through pannexin-1 (Panx1) channels to mediate joint pain. My overarching hypothesis is that microglial Panx1 channels critically modulate arthritis joint pain and that silencing peripheral afferents suppresses microglial reactivity following joint injury. In rats, joint pain caused by intra-articular injection of monosodium iodoacetate (MIA) was associated with spinal adenosine triphosphate (ATP) release and an increase in spinal microglial reactivity. Here, I provide evidence that both C- and A-afferents modulate the development of mechanical allodynia in a model of MIA-induced joint pain. I also demonstrate that specific ablation of either peptidergic or non-peptidergic afferents can attenuate mechanical allodynia, decrease spinal microglial reactivity and suppress extracellular ATP concentration in the CSF of animals with MIA-induced joint damage. Following joint injury, I show a microglial-specific upregulation of P2X7-receptors (P2X7R). P2X7Rs drive pannexin-1 (Panx1) channel activation and, in rats with mechanical allodynia, Panx1 function is increased in spinal microglia. Specifically, I demonstrate that microglial Panx1-mediated release of the pro-inflammatory cytokine interleukin-1 (IL-1) induces mechanical allodynia in the MIA-injected hindlimb. Furthermore, I provide evidence that mice with a microglial-specific genetic deletion of Panx1 are protected from developing mechanical allodynia. Finally, I show that the clinically utilized broad-spectrum Panx1 blocker, probenecid, attenuates MIA-induced mechanical allodynia in two experimental models of arthritis and normalizes responses in the dynamic weight-bearing test, without impacting acute nociception. In conclusion, this thesis identifies that spinal microglial Panx1 channels are critically involved in the development of arthralgia and that Panx1-targeted therapy is a new mechanistic approach for alleviating joint pain.

The Teeth of Time: Pierre Hadot on Meaning and Misunderstanding in the History of Ideas

Publisher: name: Columbia University
Year: 2011
Subjects: subject: Philosophy
subject: FOS: Philosophy, ethics and religion

description: The French philosopher and intellectual historian Pierre Hadot (1922-2010) is known primarily for his conception of philosophy as spiritual exercise, which was an essential reference for the later Foucault. An aspect of his work that has received less attention is a set of methodological reflections on intellectual history and on the relationship between philosophy and history. Hadot was trained initially as a philosopher and was interested in existentialism as well as in the convergence between philosophy and poetry. Yet he chose to become a historian of philosophy and produced extensive philological work on neo-Platonism and ancient philosophy in general. He found a philosophical rationale for this shift in his encounter with Wittgenstein's philosophy in the mid-1950s (Hadot was one of Wittgenstein's earliest French readers and interpreters). For Hadot, ancient philosophy must be understood as a series of language games, and each language game must be situated within the concrete conditions in which it happened. The reference to Wittgenstein therefore supports a strongly contextualist and historicist stance. It also supports its exact opposite: presentist appropriations of ancient texts are entirely legitimate, and they are the only way ancient philosophy can be existentially meaningful to us. Hadot addresses the contradiction by embracing it fully and claiming that his own practice aims at a coincidence of opposites (a concept borrowed from the Heraclitean tradition). For Hadot the fullest and truest way of doing philosophy is to be a philosopher and a historian at the same time.

description: Recognizing visual content in unconstrained videos has become a very important problem for many applications. Existingcorpora for video analysis lack scale and/or content diversity,and thus limited the needed progress in this critical area. In this paper, we describe and release a new database called CCV, containing 9,317 web videos over 20 semantic categories, including events like “baseball” and “parade”, scenes like “beach”, and objects like “cat”. The database was collected with extra care to ensure relevance to consumer interest and originality of video content without post-editing. Such videos typically have very little textual annotation and thus can benefit from the development of automatic content
analysis techniques. We used Amazon MTurk platform to perform manual annotation, and studied the behaviors and performance of human annotators on MTurk.We also compared the abilities in understanding consumer video content by humans and machines. For the latter, we implemented automatic classifiers using state-of-the-art multi-modal approach that achieved top performance in recent TRECVID multimedia event detection task. Results confirmed classifiers fusing audio and video features significantly outperform single-modality solutions. We also found that humans are much better at understanding categories of nonrigid objects such as “cat”, while current automatic techniques are relatively close to humans in recognizing categories that have distinctive background scenes or audio patterns.

description: Motivated by vision tasks such as robust face and object recognition, we consider the following general problem: given a collection of low-dimensional linear subspaces in a high-dimensional ambient (image) space, and a query point (image), efficiently determine the nearest subspace to the query in ℓ1 distance. We show in theory this problem can be solved with a simple two-stage algorithm: (1) random Cauchy projection of query and subspaces into low-dimensional spaces followed by efficient distance evaluation (ℓ1 regression); (2) getting back to the high-dimensional space with very few candidates and performing exhaustive search. We present preliminary experiments on robust face recognition to corroborate our theory.

description: My art explores identity, femininity, vulnerability, and place with a focus on the effects of climate change on the craft and cultural practices in some rural communities in Nigeria. To do this, I incorporate traditional Nigerian fabrics including aso-oke fabric and techniques such as unravelling, scratching, cutting, bleaching and dyeing to represent the change and alteration in crafts and cultural practices of rural communities in Nigeria. This thesis is a compilation of the works I have done in my MFA program. It was inspired by my one-year National Youth Service experience in a rural community in Delta State, Nigeria. My focus on women is largely hinged on my experience while I was in that community. I observed that majority of the women in that community make the economy thrive because they are more involved in agriculture. In many rural communities in Nigeria, the majority of people are fully engaged in the agricultural sector for food and other means of livelihood, which includes cultural practices and crafts. Therefore, any challenge in the environment as a result of climate change poses a threat to the people. My creative research is focused on showing the effects of climate change on cultural practices (such as pottery, body markings, basket weaving, tie-dying and fabric weaving), in some rural communities in Nigeria.

Dynamical Thin Disks

description: Thin disk accretion is often modeled in highly dynamical settings using the two-dimensional equations of viscous hydrodynamics, with viscosity representing unresolved turbulence. These equations are supposed to arise after vertical integration of the full three-dimensional equations of hydrodynamics, under the assumption of a geometrically thin disk with mirror symmetry about the midplane. But in the dynamical context, vertical dynamics are neglected by incorrectly assuming instantaneous vertical hydrostatic equilibrium. The resulting errors in the local disk height couple to the horizontal dynamics through some viscosity prescriptions and gravitational softening models. Furthermore, the viscous terms in the horizontal equations are only complete if they are inserted after vertical integration, as if the system is actually two-dimensional. Since turbulence breaks mirror symmetry, it is more physically correct to insert a turbulence model at the three-dimensional level, and impose mirror symmetry only on average. Thus, some viscous terms are usually missing. We revisit the vertical integration procedure, restricting to the regime of a Newtonian, non-self-gravitating disk. We obtain six evolution equations with only horizontal dependence, which determine the local vertical position and velocity of the disk surface, in addition to the usual fluid variables. This "2.5-dimensional" formulation opens the door to efficiently study vertical oscillations of thin disks in dynamical settings, and to improve the treatment of unresolved turbulence. As a demonstration, by including viscous stress at the three-dimensional level, we recover missing viscous terms which involve the vertical variables. We also propose a resummation of the vertically integrated gravitational force, which has a strikingly similar form to a gravitational softening model advocated for in protoplanetary disk studies.

Caustic echoes from a Schwarzschild black hole

description: We present the first numerical construction of the scalar Schwarzschild Green function in the time-domain, which reveals several universal features of wave propagation in black hole spacetimes. We demonstrate the trapping of energy near the photon sphere and confirm its exponential decay. The trapped wavefront propagates through caustics resulting in echoes that propagate to infinity. The arrival times and the decay rate of these caustic echoes are consistent with propagation along null geodesics and the large l-limit of quasinormal modes. We show that the four-fold singularity structure of the retarded Green function is due to the well-known action of a Hilbert transform on the trapped wavefront at caustics. A two-fold cycle is obtained for degenerate source-observer configurations along the caustic line, where the energy amplification increases with an inverse power of the scale of the source. Finally, we discuss the tail piece of the solution due to propagation within the light cone, up to and including null infinity, and argue that, even with ideal instruments, only a finite number of echoes can be observed. Putting these pieces together, we provide a heuristic expression that approximates the Green function with a few free parameters. Accurate calculations and approximations of the Green function are the most general way of solving for wave propagation in curved spacetimes and should be useful in a variety of studies such as the computation of the self-force on a particle.

description: The differential λ-calculus was introduced to study the resource usage of programs. This thesis marks a change in that belief system; our thesis can be summarized by the analogy λ-calculus : functions ::∂λ-calculus : smooth functions. To accomplish this, we will describe a precise categorical semantics for the differential λ-calculus using categories with a differential operator. We will then describe explicit models that are relevant to differential geometry, using categories like Sikorski spaces and diffeological spaces.

The Republican Tale of Two Commercials

subject: FOS: Political science

description: The author states that Republican reaction to a commercial by Chrysler was a result of misreading the commercial.  The author also criticizes a commercial by Pete Hoekstra, a Republican Senate candidate in Michigan.  The author writes, "Together these two commercials, and the reactions to them, demonstrate how the Republicans have backed themselves into an angry, insensitive and cynical corner. The optimism which came naturally to Reagan, through which whose presidency I lived and for whom I am no apologist, has no place in the angry Republican Party of the 21st Century. Instead, the Republicans find themselves disagreeing and yelling foul at a commercial urging Americans to keep fighting and never give up while being reduced to making fun of names and accents in their campaigns."
