Assessing the “Education Debt”: Teach For America and the Problem of Attrition
Creators: name: Anderson, Ashlee
Publisher: name: Critical Education
Year: 2019

description: With this paper, I explore the impact of teacher attrition on Teach For America’s (TFA) ability to produce more long-term, systemic educational change.  I do so via my application of critical race theory and Gloria Ladson-Billings’ concept of the “education debt” to TFA’s consistently high rates of attrition.  I begin with a general discussion of long-term educational change, paying particular attention to how and why teacher attrition matters.  Next, I present the four components of Ladson-Billings’ (2006a) conception of the “education debt,” after which I explore just one factor that I believe may prevent the realization of TFA’s goal of ending educational inequity (teacher attrition) in both practical and moral terms.  Using critical race theory as an additional level of analysis that is consistent with Ladson-Billings “education debt” framework, I conclude that TFA’s concrete materiality falls short of its intention to end educational inequity, especially concerning the longevity of its recruits.  This, I contend, suggests the need for educational resources to be equitably redistributed, in part, via high quality educators for our most under-served youth populations, including those currently taught by TFA.

Ethical, Legal, and Pedagogical Issues in edTPA
Creators: name: Gilbert, Kristen A.
name: Kuo, Nai-Cheng
Publisher: name: Critical Education
Year: 2019

description: The purpose of this article is to address ethical, legal, and pedagogical issues in the use of edTPA, a mandatory and consequential assessment required for teacher candidates in many states. We discuss issues such as the cost of edTPA, implicit bias in scoring teacher candidates, marginalization in K-12 settings, property rights, privacy, and disconnections between the real classroom and what teacher candidates are asked to do in edTPA. At the end of the paper we make three suggestions. First, edTPA can be used as a learning progression assessment, but not a high-stakes assessment. Second, private publishers should play an assistive role, not a dominant role, in teacher education. Third, educators should examine the rubrics of edTPA within and across disciplines to reduce inappropriate practices.

Studies on the roles of lipids in membrane structure and function
Creators: name: Bally, Marcel B.
Publisher: name: University of British Columbia
Year: 2010

description: Lipids in membranes satisfy two basic roles. First they provide a matrix with which membrane proteins are associated and second, they provide a structural bilayer for maintaining a permeability barrier. This thesis investigates certain aspects of the structural and permeability barrier properties of lipids employing simple protein free model membrane systems. It is demonstrated, employing ³¹P and ²H NMR techniques, that cholesterol engendered formation of non-bilayer structures in multilamellar vesicles (MLVs) composed of phosphatidylethanolamine (PE) and either phosphatidylserine (PS) or phosphatidylcholine (PC). Further the presence of cholesterol, in conjunction with Mg²⁺, facilitated Ca²⁺triggered formation of non-bilayer organizations in the PS containing systems. It is indicated that in these complex multicomponent systems where multiple structural phases (ie. bilayer, hexagonal, and "isotropic") coexist, that the phospholipids exhibit ideal mixing behaviour. A basic consequence of the barrier properties of a lipid bilayer is an ability to maintain a membrane potential (Δψ), which is required for a variety of membrane mediated transport processes. To investigate the role of lipids in maintaining Δψ, and the direct effect of Δψ on transport functions, a large unilamellar vesicle (LUV) preparation free of impurities is required. This thesis describes a novel procedure for generating LUVs, by extrusion of MLVs through polycarbonate filters (pore size 100 nm). LUVs can thus be obtained from a wide variety of lipid species and mixtures in the absence of lipid solubilizing agents. Vesicles exhibiting Δψ in response to a Na⁺/K⁺ ion gradient (K⁺ inside) are characterized. It is shown that such a K⁺ diffusion potential can drive the uptake of a variety of biologically active molecules (eg. local anaesthetics, antineoplastic agents, biogenic amines (dopamine)) which have cationic and lipophilic characteristics. The transport process appears to proceed by a antiport cation/lipophilic cation exchange process that is driven by the transmembrane potential.

description: Exact results for the first passage time and leapover statistics of symmetric and one-sided Levy flights (LFs) are derived. LFs with stable index alpha are shown to have leapover lengths, that are asymptotically power-law distributed with index alpha for one-sided LFs and, surprisingly, with index alpha/2 for symmetric LFs. The first passage time distribution scales like a power-law with index 1/2 as required by the Sparre Andersen theorem for symmetric LFs, whereas one-sided LFs have a narrow distribution of first passage times. The exact analytic results are confirmed by extensive simulations.

subject: FOS: Physical sciences

description: We introduce the concept of quantum tensor product expanders. These are expanders that act on several copies of a given system, where the Kraus operators are tensor products of the Kraus operator on a single system. We begin with the classical case, and show that a classical two-copy expander can be used to produce a quantum expander. We then discuss the quantum case and give applications to the Solovay-Kitaev problem. We give probabilistic constructions in both classical and quantum cases, giving tight bounds on the expectation value of the largest nontrivial eigenvalue in the quantum case.

description: We use an infrared dataset captured between 1984 and 2017 using several instruments and observatories to report five rare equatorial disturbances that completely altered the appearance of Jupiter's Equatorial Zone (EZ): the clearance of tropospheric clouds revealed a new 5-$μ$m-bright band encircling the planet at the equator, accompanied by large 5-$μ$m-bright filaments. Three events were observed in ground-based images in 1973, 1979 and 1992. We report and characterize for the first time the entire evolution of two new episodes of this unusual EZ state that presented their maximum 5-$μ$m-brightness in December 1999 and February 2007, coinciding with a brown coloration south of the equator and with large bluish filaments and white plumes in the northern EZ at visible wavelengths. We characterize their typical infrared-bright lifetimes of 12-18 months, with possible periodicities of 6-8 or 13-14 years. We predict that a full-scale equatorial disturbance could occur in 2019-21.

description: The Discrete Event System Specification formalism (DEVS), which supports hierarchical and modular model composition, has been widely used to understand, analyze and develop a variety of systems. DEVS has been implemented in various languages and platforms over the years. The DEVStone benchmark was conceived to generate a set of models with varied structure and behavior, and to automate the evaluation of the performance of DEVS-based simulators. However, DEVStone is still in a preliminar phase and more model analysis is required. In this paper, we revisit DEVStone introducing new equations to compute the number of events triggered. We also introduce a new benchmark, called HOmem, designed as an alternative version of HOmod, with similar CPU and memory requirements, but with an easier implementation and analytically more manageable. Finally, we compare both the performance and memory footprint of five different DEVS simulators in two different hardware platforms.

description: The low-mass end of the supermassive black hole mass function is unknown and difficult to determine. Here we discuss our successful program to find active nuclei of late type "normal" galaxies using X-ray detections and multiwavelength identifications. We conclude that most of the Chandra detected nuclear X-ray sources are AGNs. We then outline methods of black hole mass determination when broad emission lines are unobservable.

description: Excerpts from the report: An estimated 10,365 frozen food locker and freezer provisioning plants were operating in the United States in January 1961. This was 490 more plants than were operating a year earlier. Indications are that between 85 and 90 percent of all plants provide locker rental service in addition to processing and merchandising services. The remaining plants have no lockers but specialize in processing and merchandising frozen foods, principally to homefreezer owners. The increase in total number of plants is due largely to the increasing number of these homefreezer provisioning plants. Many States have amended, or are considering amending, their "frozen food locker" laws to include under these laws those plants not renting lockers but engaged in the freezer provisioning business. Generally these plants are required to obtain licenses and conform to standards established for frozen food locker plants, such as standards of sanitation, and requirements regulating labeling, processing equipment, and facilities.

description: Project management is a critical practice to achieve specific goals and success criteria in a given time and budget. It applies knowledge of skills, tools, and deliverables to ensure a solid path within the primary constraints - known as quality, scope, time, and cost (Harned, N.D.). Other crucial areas include human resources, communications, integration, procurement, risk management, and stakeholder management. The objective of project management is to shape and reform client's objectives, establishing them through the process of organizing resources. Managed resources include finances, technology, personnel, and intellectual property. If the objectives are too tightly prescribed, decision making can be detrimental. Besides engineering and construction, project management is lately associated with health care and information technology as these industries have a complex set of components in need to be assembled in a well-structured functional method. Project managers are given the duties of taking high-level corporate visions, delivering tangible results and ensuring sufficient resources to build, test, and deploy a product (Labarre, 2019). Often, Gantt charts and PERT charts will be used to illustrate workflow and determine which tasks belong to which department.

description: This paper presents the current version of our (Elementary) Mathematical Data Model ((E)MDM), which is based on the naïve theory of sets, relations, and functions, as well as on the first-order predicate calculus with equality. Many real-life examples illustrate its 4 types of sets, 4 types of functions, and 76 types of constraints. This rich panoply of constraints is the main strength of this model, guaranteeing that any data value stored in a database is plausible, which is the highest possible level of syntactical data quality. A (E)MDM example scheme is presented and contrasted with some popular family tree software products.

This study will clarify its nature by empirically assessing on the effects of service quality on customer's perceptions and satisfaction. This study will use the SERVQUAL model and other measurement methods to examine and analyze the case. Divergent methodologies are conducted to examine the distinct antecedent causes and consequential effects. Key findings will be based on the conceptual framework and five dimensions: assurance, tangibles, responsiveness, reliability, and empathy. According to research, customers are not satisfied with unprofessional service providers, unorganized schedule, and pricing that do not meet expectations.

description: We find the full spectrum of fermion bound states on a Z_2 kink. In addition to the zero mode, there are int[2 m_f/m_s] bound states, where m_f is the fermion and m_s the scalar mass. We also study fermion modes on the background of a well-separated kink-antikink pair. Using a variational argument, we prove that there is at least one bound state in this background, and that the energy of this bound state goes to zero with increasing kink-antikink separation, 2L, and faster than e^{-a2L} where a = min(m_s, 2 m_f). By numerical evaluation, we find some of the low lying bound states explicitly.

description: Excerpts from the report: In selecting the sample associations for this case study report, a limited number of the associations responding to our mail questionnaire were requested to submit copies of their plans for thorough review. Representative plans from this group were then selected for detailed study, including personal interviews with management and other personnel of the cooperatives involved. This report covers detailed plans of five selected associations. Detailed information covering the complete incentive system of the selected cooperatives is presented in the following sections of this report for each association. Before discussing the individual plans, however, a few general comments regarding method of presentation, the associations, and their incentive programs should be helpful. Each case is presented separately. A general comment preceding the incentive plans of each association provides basic information on the cooperatives themselves. This was considered necessary to give perspective and a setting to make the plans more meaningful.

description: We report the crystal structure and magnetic behavior of the $4d^3$ spin-$\frac32$ silicophosphate MoP$_3$SiO$_{11}$ studied by high-resolution synchrotron x-ray diffraction, neutron diffraction, thermodynamic measurements, and ab initio band-structure calculations. Our data revise the crystallographic symmetry of this compound and establish its rhombohedral space group ($R\bar 3c$) along with the geometrically perfect honeycomb lattice of the Mo$^{3+}$ ions residing in disconnected MoO$_6$ octahedra. Long-range antiferromagnetic order with the propagation vector $\mathbf k=0$ observed below $T_N=6.8$ K is a combined effect of the nearest-neighbor in-plane exchange coupling $J\simeq 2.6$ K, easy-plane single-ion anisotropy $D\simeq 2.2 $ K, and a weak interlayer coupling $J_c\simeq 0.8$ K. The 12% reduction in the ordered magnetic moment of the Mo$^{3+}$ ions and the magnon gap of $Δ\simeq 7$ K induced by the single-ion anisotropy further illustrate the impact of spin-orbit coupling on the magnetism. Our analysis puts forward single-ion anisotropy as an important ingredient of $4d^3$ honeycomb antiferromagnets despite their nominally quenched orbital moment.

description: We study the effects of the rippling of the graphene sheet on the quasiparticle dispersion. This is achieved using a generalization to the honeycomb lattice of the Momentum Average approximation, which is accurate for all coupling strengths and at all energies. We show that even though the position of the Dirac points may move and the Fermi speed can be renormalized significantly, quasiparticles with very long lifetimes survive near the Dirac points even for very strong couplings.

Performance of a dual-fuel prechamber diesel engine with natural gas
Creators: name: Song, Seaho
Publisher: name: University of British Columbia
Year: 2010

description: The feasibility of dual-fuel operation with natural gas in a prechamber diesel engine was studied with special emphasis on fuel consumption and cylinder pressure development. The effects of air restriction, pilot diesel flow rate and injection timing were also studied. Dual-fuel operation showed poor part-load fuel consumption; near full load the fuel consumption was close to that of straight diesel operation. In the absence of injection timing adjustment the maximum power output of dual-fuel operation was severely limited by the maximum cylinder pressure. Retarding the injection timing was effective in reducing the maximum cylinder pressure to a safe level. The analysis of apparent energy release indicates the differences in combustion mechanism between auto-ignition of diesel fuel in straight diesel operation and propagation of flame fronts in dual-fuel operation.

description: The spectrum of the Hermitian Hamiltonian $H=p^2+V(x)$ is real and discrete if the potential $V(x)\to\infty$ as $x\to\pm\infty$. However, if $V(x)$ is complex and PT-symmetric, it is conjectured that, except in rare special cases, $V(x)$ must be analytic in order to have a real spectrum. This conjecture is demonstrated by using the potential $V(x)=(ix)^a|x|^b$, where $a,b$ are real.

The catcher stops fast radioactive products and emits them as singly charged slow ions. Current ion catchers are based on stopping in He and H$_2$ gas. However, with increasing intensity of the secondary beam the amount of ion-electron pairs created eventually prevents the electromagnetic extraction of the radioactive ions from the gas cell. In contrast, such limitations are not present in thermal ionizers used with the ISOL production technique. Therefore, at least for alkaline and alkaline earth elements, a thermal ionizer should then be preferred. An important use of the TRI$μ$P facility will be for precision measurements using atom traps. Atom trapping is particularly possible for alkaline and alkaline earth isotopes. The facility can produce up to 10$^9$ s$^{-1}$ of various Na isotopes with the in-flight method. Therefore, we have built and tested a thermal ionizer. An overview of the operation, design, construction, and commissioning of the thermal ionizer for TRI$μ$P will be presented along with first results for $^{20}$Na and $^{21}$Na.

description: The collapsar model requires rapidly rotating Wolf-Rayet stars as progenitors of long gamma-ray bursts. However, Galactic Wolf-Rayet stars rapidly lose angular momentum due to their intense stellar winds. We investigate whether the tidal interaction of a Wolf-Rayet star with a compact object in a binary system can spin up the Wolf-Rayet star enough to produce a collapsar. We compute the evolution of close Wolf-Rayet binaries, including tidal angular momentum exchange, differential rotation of the Wolf-Rayet star, internal magnetic fields, stellar wind mass loss, and mass transfer. The Wolf-Rayet companion is approximated as a point mass. We then employ a population synthesis code to infer the occurrence rates of the various relevant binary evolution channels. We find that the simple scenario -- i.e., the Wolf-Rayet star being tidally spun up and producing a collapsar -- does not occur at solar metallicity and may only occur with low probability at low metallicity. It is limited by the widening of the binary orbit induced by the strong Wolf-Rayet wind or by the radius evolution of the Wolf-Rayet star that most often leads to a binary merger. The tidal effects enhance the merger rate of Wolf-Rayet stars with black holes such that it becomes comparable to the occurrence rate of long gamma-ray bursts.

description: We present experimental and theoretical results for the fluctuation properties in the incomplete spectra of quantum systems with symplectic symmetry and a chaotic dynamics in the classical limit. To obtain theoretical predictions, we extend the random-matrix theory (RMT) approach introduced in [O. Bohigas and M. P. Pato, Phys. Rev. E 74, 036212 (2006)] for incomplete spectra of quantum systems with orthogonal symmetry. We validate these RMT predictions by randomly extracting a fraction of levels from complete sequences obtained numerically for quantum graphs and experimentally for microwave networks with symplectic symmetry and then apply them to incomplete experimental spectra to demonstrate their applicability. Independently of their symmetry class quantum graphs exhibit nongeneric features which originate from nonuniversal contributions. Part of the associated eigenfrequencies can be identified in the level dynamics of parameter-dependent quantum graphs and extracted, thereby yielding spectra with systematically missing eigenfrequencies. We demonstrate that, even though the RMT approach relies on the assumption that levels are missing at random, it is possible to determine the fraction of missing levels and assign the appropriate symmetry class by comparison of their fluctuation properties with the RMT predictions.

description: The structures for the TRI$μ$P facility have been completed and commissioned. At the facility radioactive nuclides are produced to study fundamental interactions and symmetries. An important feature is the possibility to trap radioactive atoms in order to obtain and hold a pure substrate-free sample for precision measurements. In the TRI$μ$P facility a production target is followed by a magnetic separator, where radioactive isotopes are produced in inverse reaction kinematics. Separation up to 99.95% could be achieved for $^{21}$Na. A novel transmitting thermal ionizing device was developed to stop the energetic isotopes. Some 50% of stopped $^{21}$Na could be extracted and transported as low energy singly charged ions into a radio frequency quadrupole cooler and buncher with 35% transmission efficiency. The ions are transported lossless via a drift tube and a low energy electrostatic beam line into the experimental setup. Such ions can be neutralized on hot metal foils and the resulting atoms can be stored in a magneto-optical trap. The functioning of that principle was demonstrated with stable Na extracted from the thermal ionizer, radioactive beams will follow next.

Empirical and participatory democratic theories : the limits of the debate

Publisher: name: University of British Columbia

description: Democratic theory is currently divided into two opposing schools: the Participatory, whose test of democracy is direct participation in government, unambiguous popular consent, and equality of influence on- decisions; and the Empirical, which is satisfied with levels of indirect participation, tacit consent, and majority rule, in the Western democracies. This study seeks to show that the two schools share major assumptions about the definition and the justification of democracy. They assume that democracy subsists purely in a set of decision-making procedures, and that the only justification of the procedure is its pluralist approach to demands. Empirical and Participatory theorists dispute the interpretation of the principles of participation, pluralism, and political equality, but they concur that democracy requires a consensus on these procedural principles only. They also dispute the ideal form of government by consent, but they agree that the legitimacy of democratic decisions rests on the extent of individual consent. The limits of the debate arise from a confusion between democratic pluralism and moral relativism. Procedural principles define democracy only where they are part of a set of norms which includes those of authority, rationality, and the common good; a procedural consensus can guarantee democracy only where it is backed by a -shared commitment to these non-procedural or substantive norms. Since the legitimacy of political decisions depends on their conformity with rationality and the common good, and not only on their place of origin, an adequate justification of democracy must demonstrate a logical connection between these standards and the democratic system. This study states the case for such a connection, and for a normative interpretation of participation, consent, pluralism, and political equality.

description: Excerpts from the report: The Revenue Act of 1962, approved in October 1962, contains two sections (17 and 19 set forth in Appendix A) affecting the tax treatment of farmer cooperatives and their patrons and the tax reporting requirements applicable to such cooperatives. The purpose of this publication is to make available quickly information concerning these changes in the law since they will become effective as to taxable years of the cooperatives beginning after December 31, 1962. The report should not be considered an interpretation of the law. Until Treasury Regulations and interpretations are issued, farmer cooperatives will need to make their own interpretation with advice of counsel where necessary.

description: Fast and precise propagation of satellite orbits is required for mission design, orbit determination and payload data analysis. We present a method to improve the computational performance of numerical propagators and simultaneously maintain the accuracy level required by any particular application. This is achieved by determining the positional accuracy needed and the corresponding acceptable error in acceleration on the basis of the mission requirements, removing those perturbation forces whose effect is negligible compared to the accuracy requirement, implementing an efficient and precise algorithm for the harmonic synthesis of the geopotential gradient (i.e., the gravitational acceleration) and adjusting the tolerance of the numerical propagator to achieve the prescribed accuracy level with minimum cost. In particular, to achieve the optimum balance between accuracy and computational performance, the number of geopotential spherical harmonics to retain is adjusted during the integration on the basis of the accuracy requirement. The contribution of high-order harmonics decays rapidly with altitude, so the minimum expansion degree meeting the target accuracy decreases with height. The optimum degree for each altitude is determined by making the truncation error of the harmonic synthesis equal to the admissible acceleration error. This paper presents a detailed description of the technique and test cases highlighting its accuracy and efficiency.

description: We construct the metric of new multi-black hole configurations on a d-dimensional cylinder R^{d-1} x S^1, in the limit of small total mass (or equivalently in the limit of a large cylinder). These solutions are valid to first order in the total mass and describe configurations with several small black holes located at different points along the circle direction of the cylinder. We explain that a static configuration of black holes is required to be in equilibrium such that the external force on each black hole is zero, and we examine the resulting conditions. The first-order corrected thermodynamics of the solutions is obtained and a Newtonian interpretation of it is given. We then study the consequences of the multi-black hole configurations for the phase structure of static Kaluza-Klein black holes and show that our new solutions imply continuous non-uniqueness in the phase diagram. The new multi-black hole configurations raise the question of existence of new non-uniform black strings. Finally, a further analysis of the three-black hole configuration suggests the possibility of a new class of static lumpy black holes in Kaluza-Klein space.
