Student financial aid in Canada : a critique
Creators: name: Wallsmith, Courtney Michelle
Publisher: name: University of British Columbia
Year: 2011

description: Data from the Survey of Financial Security 2005 are used in this study to analyze student loan debt and to compare student loan debtors and their resulting debt-return ratios across different variables such as sex, age, region, income and programme of study. This study hypothesizes that the student financial aid programme in Canada is inefficient and inequitable. It is inefficient not only because of its complexity, but because student loan borrowers are unable to repay their loan debt in a timely fashion with the income they receive after graduation. It is inequitable because it is untargeted and focused on tax-based assistance rather than needs-based assistance, and because student loan debt differs for students of different age, sex, programme of study and region. Simple econometric methods are used to test this hypothesis and the results show a modicum of support for the hypotheses. Student loan debt and the debt-return ratio tend to differ depending on sex, age, region, income and education programme. As a supplement, this study also describes the financial aid system and discusses its problems. It further explains why education is important to both the individual and society as a whole and why access to an efficient and equitable system of financial aid is important in terms of John Rawls’ theory of justice. Finally, this paper provides some solutions to the financial aid system’s problems.

Regionalism and Multilateral Tariff Cooperation
Creators: name: Bagwell, Kyle

Publisher: name: Columbia University
Year: 1996
Subjects: Economics

description: We consider a three country world in which each country's import market is served by competing exporters from it's two trading partners. We assume that weak multilateral enforcement mechanisms prevent governments from implementing efficient trade policies through a multilateral agreement that requires tariffs to conform to the most favored nation (MFN) principle. We then ask whether exceptions from MFN for thepirpose of forming preferential agreements can lead to lower external tariffs, and thereby to a more efficient tariff structure under the multicultural agreement. We identify three opposing effects of preferential agreements on the multilateral tariff structure in this setting. A first effect, the tariff complementarity effect, works to reduce the desired external tariffs of countries that join together in a preferential agreement. Two additional effects of preferential agreements arise only when enforcement issues at the multilateral level are considered. One of these, punishment effect, weakens the ability of the member countries of a preferential agreement to punish deviations from the multilateral agreement. The other of these, the tariff discrimination effect, allows countries to discriminate against those who would "free ride" under MFN, and there for works to increase the desired external tariffs of countries that join together in a preferential agreement. The relative strengths of these three effects determine the impact of preferential agreement on the tariff structure under the multilateral agreement. Our findings suggest that preferential agreements can have their most desiravel effects on the multilateral system when the degree of multilateral cooperation is low.

description: We investigate the superfluid state of repulsively interacting three-component (color) fermionic atoms in optical lattices. When the anisotropy of the three repulsive interactions is strong, atoms of two of the three colors form Cooper pairs and atoms of the third color remain a Fermi liquid. An effective attractive interaction is induced by density fluctuations of the third-color atoms. This superfluid state is stable against changes in filling close to half filling. We determine the phase diagrams in terms of temperature, filling, and the anisotropy of the repulsive interactions.

description: In Canada, water utilities are traditionally managed by municipal governments. Declining financial support from senior levels of government, public service reforms, and provincial policy interests in the 1990s caused Canadian municipalities to consider reforming their local water utilities. The current water governance literature argues that local financial circumstances condition the types of public policy decisions and governance reforms municipalities make, making these decisions contextual. However, amid similar political and economic circumstances, municipal governments in Calgary, Edmonton, Toronto and Hamilton chose distinctly different governance models. Calgary considered privatizing its water utility, later reorganizing its department as a business unit. Edmonton considered privatization, only to corporatize its water utility alongside its electric utility. In Toronto, the city considered a municipal corporation, and a quasi-independent service board, only to keep its water utility a separate business unit. Hamilton signed a private contract, only to recreate a municipal water department after the contract ended. I argue that local dynamics conditions the decision-making process in municipalities, where politicians must balance the ideas and interests of local actors when making policy decisions. This thesis then, examines the decision-making process in each city between 1990 and 2005, demonstrating that water reform, and municipal public policy more broadly, is both contentious and politically driven.
Collusion with persistent cost shocks

Year: 2004
Subjects: Economics

description: We consider a dynamic Bertrand game, in which prices are publicly observed and each firm receives a privately observed cost shock in each period. Although cost shocks are independent across firms, within a firm costs follow a first-order Markov process. We analyze the set of collusive equilibria available to firms, emphasizing the best collusive scheme for the firms at the start of the game. In general, there is a tradeoff between productive efficiency, whereby the low-cost firm serves the market in a given period, and high prices. We show that when costs are perfectly correlated over time within a firm, if the distribution of costs is log concave and firms are sufficiently patient, then the optimal collusive scheme entails price rigidity: firms set the same price and share the market equally, regardless of their respective costs. Productive efficiency can be achieved in equilibrium under some circumstances, but such equilibria are not optimal. When serial correlation of costs is imperfect, partial productive efficiency is optimal. For the case of two cost types, first-best collusion is possible if the firms are patient relative to the persistence of cost shocks, but not otherwise. We present numerical examples of first-best collusive schemes.
Use of quantum quenches to probe the equilibrium current patterns of ultracold atoms in an optical lattice

description: Atomic bosons and fermions in an optical lattice can realize a variety of interesting condensed matter states that support equilibrium current patterns in the presence of synthetic magnetic fields or non-abelian gauge fields. As a route to probing such mass currents, we propose a nonequilibrium quantum quench of the Hamiltonian that dynamically converts the current patterns into experimentally measurable real-space density patterns. We illustrate how a specific such "unidirectional" quench of the optical lattice can be used to uncover checkerboard and stripe current orders in lattice Bose superfluids and Fermi gases, as well as chiral edge currents in an integer quantum Hall state.

description: We present a framework for understanding and interpreting reciprocity and nondiscrimination, the two principles that are the pillars of the multilateral trading system as embodied in GATT and its successor, the WTO. We show that GATT's principle of reciprocity serves to neutralize the world-price effects of a country's trade policy decisions, and hence can deliver efficient trade-policy outcomes for its member governments provided that the externalities associated with trade intervention travel through world prices. We then establish that externalities indeed travel in this way if and only if tariffs also conform to the principle of non-discrimination (MFN). In this way, the principles of reciprocity and non-discrimination can work in concert to deliver efficient outcomes for the multilateral trading system. We also consider within our framework the implications of preferential agreements for the multilateral trading system. The introduction of free trade agreements complicates the way in which externalities are transmitted across countries, and in this environment the principle of reciprocity and deliver an efficient multilateral trade agreement in the presence of preferential agreements. Instead, our results offer support for the view that preferential agreements pose a threat to existing multilateral system.
Collusion and price rigidity

description: We consider an infinitely repeated Bertrand game, in which prices are publicly observed and each firm receives a privately observed, i.i.d. cost shock in each period. We focus on symmetric perfect public equilibria (SPPE), wherein any "punishments" are borne equally by all firms. We identify a tradeoff that is associated with collusive pricing schemes in which the price to be charged by each firm is strictly increasing in its cost level: such "fully sorting" schemes offer efficiency benefits, as they ensure that the lowest-cost fim makes the current sale, but they also imply an informational cost (distorted pricing and/or equilibrium-path price wars), since a higher-cost firm must be deterred from mimicking a lower-cost firm by charging a lower price. A rigid-pricing scheme, where a firm's collusive price is independent of its current cost position, sacrifices efficiency benefits but also diminishes the informational cost. For a wide range of settings, the optimal symmetric collusive scheme requires (i). the absence of equilibrium-path price wars and (ii). a rigid price. If firms are sufficiently impatient, however, the rigid-pricing scheme cannot be enforced, and the collusive price of lower-cost firms may be distorted downward, in order to diminish the incentive to cheat. When the model is modified to include i.i.d. public demand shocks, the downward pricing distortion that accompanies a firm's lower-cost realization may occur only when current demand is high.

description: The purpose of this case study was to gain insight into how experienced middle school principals understand the concept of instructional leadership and, further, perceive their enactments of instructional leadership to build the instructional capacity of the teachers in their schools. Research into instructional leadership indicates that school principals contribute indirectly to school effectiveness and student achievement through actions (practices) that influence the type and quality of instruction in schools and classrooms; however, there is limited research on this topic that is specific to leadership in middle schools. The study used qualitative case study methodology involving semi-structured interviews with five experienced middle school principals, all from a large, urban public school district in Alberta. The findings of this inquiry revealed six key themes. Middle school principals in this study: (a) have a strong theoretical understanding of leadership for learning, (b) define their practices of instructional leadership through shared leadership, PLC structures, and a focus on relationships, (c) perceive their practices of instructional leadership to include developing leadership capacity of others, (d) share beliefs and understandings, and enact practices of instructional leadership that are strongly influenced by a specific body of leadership literature that is promoted through district-led professional learning initiatives, (e) believe there are contextual differences that impact not just their leadership generally, but their instructional leadership, and (f) have a sophisticated theoretical understanding of instructional leadership and leadership for learning; however, they struggle to provide evidence of how their practices impact teachers’ instructional capacity and student learning. The findings of my study contribute to the growing body of knowledge related to instructional leadership, especially as it focuses on middle schools.

description: It is well known that opportunistic scheduling algorithms are throughput optimal under full knowledge of channel and network conditions. However, these algorithms achieve a hypothetical achievable rate region which does not take into account the overhead associated with channel probing and feedback required to obtain the full channel state information at every slot. We adopt a channel probing model where $β$ fraction of time slot is consumed for acquiring the channel state information (CSI) of a single channel. In this work, we design a joint scheduling and channel probing algorithm named SDF by considering the overhead of obtaining the channel state information. We first analytically prove SDF algorithm can support $1+ε$ fraction of of the full rate region achieved when all users are probed where $ε$ depends on the expected number of users which are not probed. Then, for homogenous channel, we show that when the number of users in the network is greater than 3, $ε> 0$, i.e., we guarantee to expand the rate region. In addition, for heterogenous channels, we prove the conditions under which SDF guarantees to increase the rate region. We also demonstrate numerically in a realistic simulation setting that this rate region can be achieved by probing only less than 50% of all channels in a CDMA based cellular network utilizing high data rate protocol under normal channel conditions.

description: Adding adaptation capabilities to existing distributed systems is a major concern. The question addressed here is how to retrofit existing systems with self-healing, adaptation and/or self management capabilities. The problem is obviously intensified for 'systems of systems' composed of components, whether new or legacy, that may have been developed by different vendors, mixing and matching COTS and 'open source' components. This system composition model is expected to be increasingly common in high performance computing. The usual approach is to train technicians to understand the complexities of these components and their connections, including performance tuning parameters, so that they can then manually monitor and reconfigure the system as needed. We envision instead attaching a 'standard' feedback loop infrastructure to existing distributed systems for the purposes of continual monitoring and dynamically adapting their activities and performance. (This approach can also be applied to 'new' systems, as an alternative to 'building in' adaptation facilities, but we do not address that here.) Our proposed infrastructure consists of multiple layers with the objectives of probing, measuring and reporting of activity and state within the execution of the legacy system among its components and connectors; gauging, analysis and interpretation of the reported events; and possible feedback to focus the probes and gauges to drill deeper, or when necessary - direct but automatic reconfiguration of the running system.
Learning the Probability Distribution for Probabilistic Expert Systems

Year: 1989
Subjects: Computer science

description: This paper describes a method for learning the joint probability distribution of a set of variables from a sample of instances from the domain. The method is based on a straightforward application of Bayes Law to the problem of estimating individual probabilities from a probability distribution. We use a maximum entropy distribution as an initial estimate and show how this estimate can be easily updated each time an additional example is observed. Although developed for the purpose of estimating the conditional probabilities required for Bayesian inference networks, this method can be adopted to simplify knowledge acquisition in any expert system that uses knowledge in the form of probabilities.

description: We discuss some general properties of "defect branes", i.e. branes of co-dimension two, in (toroidally compactified) IIA/IIB string theory. In particular, we give a full classification of the supersymmetric defect branes in dimensions 2 < D < 11 as well as their higher-dimensionalstring and M-theory origin as branes and a set of "generalized" Kaluza-Klein monopoles. We point out a relation between the generalized Kaluza-Klein monopole solutions and a particular type of mixed-symmetry tensors. These mixed-symmetry tensors can be defined at the linearized level as duals of the supergravity potentials that describe propagating degrees of freedom. It is noted that the number of supersymmetric defect branes is always twice the number of corresponding central charges in the supersymmetry algebra.

Incremental Dynamic Semantics for Language-Based Programming Environments
Creators: name: Kaiser, Gail E.
Publisher: name: Columbia University
Year: 1988
Subjects: Computer science

description: Attribute grammars are a formal notation for expressing the static semantics of programming languages — those properties that can be derived from inspection of the program text. Attribute grammars have become popular as a mechanism for generating language-based programming environments that incrementally perform symbol resolution, type checking, code generation and derivation of other static semantic properties as the program is modified. However, attribute grammars are not suitable for expressing dynamic semantics — those properties that reflect the history of program execution and/or user interactions with the programming environment. This article presents action equations, an extension of attribute grammars suitable for specifying the static and the dynamic semantics of programming languages. It describes how action equations can be used to generate language-based programming environments that incrementally derive static and dynamic properties as the user modifies and debugs the program.
Data Combination over 10 years with ALMA: Techniques for Interferometry and Total Power Imaging

Year: 2023

description: ALMA is an incredibly versatile facility that provides mm-wave images down to sub-arcsecond resolution, as well as total power (single-dish) images sensitive to larger scales. Complementary observations with the baseline array and Morita Atacama Compact Array (ACA) are vital for recovering the true flux distribution of spatially resolved astronomical sources accompanied by extended emission. In Plunkett et al. (2023), an international community-driven working group provides an overview of the prominent available methods to combine single-dish and interferometric observations. In this poster, we describe a suite of test cases and assessment tools used to evaluate data combination methods. Most importantly, we present publicly available scripts, enabling ALMA users to perform their own data combination and ensure high-quality science images of spatially resolved objects.

description: We present a theoretical model for the study of exciton dynamics in J-aggregated monolayers of fluorescent dyes. The excitonic evolution is described by a Monte-Carlo wave function approach which allows for a unified description of the quantum (ballistic) and classical (diffusive) propagation of an exciton on a lattice in different parameter regimes. The transition between the ballistic and diffusive regime is controlled by static and dynamic disorder. As an example, the model is applied to three cyanine dye J-aggregates: TC, TDBC, and U3. Each of the molecule-specific structure and excitation parameters are estimated using time-dependent density functional theory. The exciton diffusion coefficients are calculated and analyzed for different degrees of film disorder and are correlated to the physical properties and the structural arrangement of molecules in the aggregates. Further, exciton transport is anisotropic and dependent on the initial exciton energy. The upper-bound estimation of the exciton diffusion length in the TDBC thin-film J-aggregate is of the order of hundreds of nanometers, which is in good qualitative agreement with the diffusion length estimated from experiments.

Climatic changes

description: The greatest challenges facing the public health systems of today include an aging population, urbanization and climate change. A key component of climate variability and climate change adaptation is the training of a new generation of leaders to understand the role that climate plays in driving disease burden and impacting economic growth. Such capacity building will help to strengthen and improve decisions made in the public health sector to minimize the impacts of global environmental change. As a contribution to this process, The International Research Institute for Climate and Society (IRI), in partnership with the Center for International Earth Science Information Network (CIESIN) and the Mailman School of Public Health (MSPH) at Columbia University initiated this two-week course in 2008. Building on the response of our 2008-2010 alumni, and a great demand from the climate and health community the 2011 Summer Institute on Climate Information for Public Health (SI11) was designed to engage professionals who play a key role in the operational decision-making for climate-sensitive diseases in identifying and evaluating appropriate use of climate information. SI11 was held at Columbia University's Lamont-Doherty Campus in Palisades, New York, between May 16th and May 27th, 2011.
The development of optical measurement techniques for gas species and surface temperature on a planar SOFC methane-steam reformer
Creators: name: Saunders, James Edward Appleby
Publisher: name: University of British Columbia
Year: 2011

description: This thesis presents the development of an experimental apparatus and methods to allow the application of gaseous Raman spectroscopy to the challenging and original application of a small-scale, high-temperature methane/steam reformer developed to be representative of the technologies used in solid oxide fuel cell (SOFC) applications. The research is placed in the context of global energy trends and SOFC’s, with specific reference to the challenges related to directly internally reforming medium-temperature SOFC’s and the case for the development of non-intrusive measurement techniques for gas species and temperature is made. The practical aspects of the development of the broadband 308 nm Raman system are examined and previous works in this area are highlighted. The excitation light source is evaluated, the use of a liquid potassium hydrogen phthalate filter as a means to reduce Rayleigh line effects is demonstrated, and background fluorescence suppression through polarization of the 308 nm light source is presented. The arrangements of the experimental set-up, gas supply, metering, and humidification are shown, as are the optical arrangements for laser sheet formation and light collection. A description of the calibration experiments, procedures, and methodologies that are used to define the normalised relative differential Raman scattering cross sections of the major species of interest in this study is presented. The observation of an unexpected leakage of air into the reformer is described and a hypothesis is presented to explain the ingress of air. Finally, results are presented that describe the response of the optically-accessed reformer to variations in; operating temperature, humidification factor, total volume flow rate, methane volume flow rate, and the methane residency time within the reformer channel. From these results it was possible to conclude that increased reformer temperature increased reaction rate, increased gas residency time in the channel increased hydrogen production, and reactant streams with higher inlet mole fractions of methane resulting in increased reaction rates and amounts of hydrogen production. The performance of the reformer rig and the suitability of optical diagnostic techniques to the application of a SOFC scale reformer are discussed.

In experiments with the data from the Novelty Track at the Text Retrieval Conference, we show improvements over a variety of approaches, in particular in raising precision scores on this data, while maintaining a reasonable amount of recall.

Towards flavour diffusion coefficient and electrical conductivity without ultraviolet contamination

description: By subtracting from a recent lattice measurement of the thermal vector-current correlator the known 5-loop vacuum contribution, we demonstrate that the remainder is small and shows no visible short-distance divergence. It can therefore in principle be subjected to model-independent analytic continuation. Testing a particular implementation, we obtain estimates for the flavour-diffusion coefficient (2 pi T D \gsim 0.8) and electrical conductivity which are significantly smaller than previous results. Although systematic errors remain beyond control at present, some aspects of our approach could be of a wider applicability.

name: Lokos, S.
Publisher: name: arXiv
Year: 2012
Subjects: subject: Nuclear Theory (nucl-th)

subject: FOS: Physical sciences

description: We generalize a previously known class of exact analytic solutions of relativistic perfect fluid hydrodynamics for the first time to arbitrary temperature-dependent Equation of State. We investigate special cases of this class of solutions, in particular, we present hydrodynamical solutions with the Equation of State determined from lattice QCD calculations. We discuss the phenomenological relevance of these solutions as well.
Structure and Abstraction in a System for Conceptual Matching
Creators: name: Shaw, David Elliot

description: The notion of a conceptual matching task is introduced as a model for a number of important practical problems in which systematically structured entities are paired on the basis of selected significant characteristics of their structures. The operation of our system centers on an active memory of limited size which serves as the site of conceptual integration, and which is distinguished from the archival memory by the availability of descriptive access mechanisms for manipulating its contents. The use of these descriptive mechanisms in elaborating and specializing high-level guiding frameworks as required in both the descriptive and matching subtasks, is illustrated.
Dynamics of localized states in extended supersymmetric quantum mechanics with multi-well potentials

description: In this paper we propose a self--consistent approach to the description of temporal dynamics of localized states. This approach is based on exactly solvable quantum mechanical models with multi-well potentials and their propagators. States of Hamiltonians with multi-well potentials form a suitable basis for the expansion of wave packets with different shapes and localization degrees. We also consider properties of the tunneling wave packets, taking into account all states of Hamiltonians with symmetric and asymmetric potentials, as well as their dependence on the degree of localization and deformations of potentials. The study of the dynamics of initially localized states shows that application of the two-state approximation for the description of tunneling is considerably limited, especially for systems, which have several states in the under-barrier region, as for example in modern superconducting quantum interference devices and traps for cold atoms.

G.729 Error Recovery for Internet Telephony
Creators: name: Rosenberg, Jonathan D.
Publisher: name: Columbia University
Year: 2001
Subjects: Computer science

description: This memorandum discusses the use of the ITU G.729 CS-ACELP speech coder on the Internet for telephony applications. In particular, the memo explores issues of error resiliency and recovery. In particular, the paper considers two questions. First, given N consecutive frame erasures (due to packet losses), how long does the decoder take to resynchronize its state with the encoder? What is the strength of the resulting error signal, both in terms of objective and subjective measures? The second issue explores which particular factors contribute to the strength of the error signal: the distortion of the speech due to the incorrect concealment of the erasures, or the subsequent distortion due to the loss of state synchronization, even though correct packets are being received. Both objective and subjective measures are used to characterize the importance of each of these two factors.
Two long HI tails in the outskirts of Abell 1367

description: We present VLA D-array HI observations of the RSCG42 and FGC1287 galaxy groups, in the outskirts of the Abell 1367 cluster. These groups are projected ~ 1.8 and 2.7 Mpc west from the cluster centre. The Arecibo Galaxy Environment survey provided evidence for HI extending over as much as 200kpc in both groups. Our new, higher resolution observations reveal that the complex HI features detected by Arecibo are in reality two extraordinary long HI tails extending for ~160 and 250 kpc, respectively, i.e., among the longest HI structures ever observed in groups of galaxies. Although in the case of RSCG42 the morphology and dynamics of the HI tail, as well as the optical properties of the group members, support a low-velocity tidal interaction scenario, less clear is the origin of the unique features associated with FGC1287. This galaxy displays an exceptionally long 'dog leg' HI tail and the large distance from the X-ray emitting region of Abell 1367 makes a ram-pressure stripping scenario highly unlikely. At the same time a low-velocity tidal interaction seems unable to explain the extraordinary length of the tail and the lack of any sign of disturbance in the optical properties of FGC1287. An intriguing possibility could be that this galaxy might have recently experienced a high-speed interaction with another member of the Coma-Abell 1367 Great Wall. We searched for the interloper responsible for this feature and, although we find a possible candidate, we show that without additional observations it is impossible to settle this issue. While the mechanism responsible for this extraordinary HI tail remains to be determined, our discovery highlights how little we know about environmental effects in galaxy groups.
