description: Web mapping is the process of designing, implementing, generating and delivering maps on the World Wide Web. With increased ease in collecting geospatial data, web mapping applications are becoming ubiquitous. Software testing is done to ensure that applications are functioning as per expectations. Results from empirical studies showed that testing has been the least emphasized aspect of web mapping application development and little is known about it. This thesis presents results of an exploratory, longitudinal case study on testing of web mapping applications. It includes resu Its of a qualitative exploratory study to understand current practices and issues faced by developers. A unit testing framework for an open-source mapping library was developed and evaluated as per requirements gathered from the exploratory study. Lessons learned after a longitudinal experience in developing and testing a web mapping application are also discussed.

An empirical analysis of network coding in peer-to-peer video-on-demand systems

description: In recent years, Peer-to-Peer (P2P) multimedia streaming has become an alternative to cable/satellite TV services. Many P2P streaming applications further provide users with DVD-like operations: play, pause, chapter selection, fast forward, and rewind. Such a real-time interactive multimedia streaming, commonly referred to as P2P Video-on­Demand (VoD), poses unique challenges in providing smooth playback and seamless interaction over the Internet. To improve the streaming quality, recent research employs network coding as the key enabling technology. However, the practicality and imple­mentation challenges of network coding received very little attention. In this thesis, we present a practical implementation of network coding in a P2P VoD system, based on which we identify the actual performance gain and design pitfalls when incorporating network coding in a P2P VoD system. Our performance analysis shows that, unlike P2P live streaming, directly applying network coding to a P2P VoD system does not necessar­ily lead to an immediate improvement in playback quality. Based on analysis, we propose Coded VoD, a new approach for P2P VoD streaming, to exploit the content sharing op­portunities in a P2P VoD session. It achieves smoother playback and shorter response time for DVD-like operations by utilizing a network-coding-based content prefetching mechanism.

We are able to image the graphene-water interface with atomic resolution, revealing a layered network of water trapped underneath the graphene. We identify water layer numbers with a carbon nanotube height reference. Under normal scanning conditions, the water structures remain stable. However, at greater electron energies, we are able to locally manipulate the water using the STM tip.

description: Objectives: To describe the dimensions of family centered bedside ward rounds and to develop recommendations for effective teaching and learning in this environment. Methods: Data were collected from focus group meetings of pediatric residents and pediatricians at the University of Calgary. Data analyses were performed according to grounded theory methodology. Hypotheses are generated about the factors influencing successful teaching and learning on rounds. Results: Dimensions that impact the rounds experience are the environment, the education and the competing priorities. Strategies for success include planning the teaching and learning experience, collaborating with families and handling the logistics. The experience of rounds is a spectrum from successful and highly educational to unsuccessful and of low educational value. The "Effectiveness of the Manager' is the core variable. Conclusions: The CanMEDS Manager Role is central to the overall experience of rounds. Implications for faculty development and resident education and evaluation are discussed.

description: We study the gravity duals of supercurrent solutions in the AdS black hole background with general phase structure to describe both the first and the second order phase transitions at finite temperature in strongly interacting systems. We argue that the conductivity and the pair susceptibility can be possible phenomenological indications to distinguish the order of phase transitions. We extend our discussion to the AdS soliton configuration. Different from the black hole spacetime, in the probe limit the first order phase transition cannot be brought by introducing the spatial component of the vector potential of the gauge field in the AdS soliton background.

description: By stacking various two-dimensional (2D) atomic crystals [1] on top of each other, it is possible to create multilayer heterostructures and devices with designed electronic properties [2-5]. However, various adsorbates become trapped between layers during their assembly, and this not only affects the resulting quality but also prevents the formation of a true artificial layered crystal upheld by van der Waals interaction, creating instead a laminate glued together by contamination. Transmission electron microscopy (TEM) has shown that graphene and boron nitride monolayers, the two best characterized 2D crystals, are densely covered with hydrocarbons (even after thermal annealing in high vacuum) and exhibit only small clean patches suitable for atomic resolution imaging [6-10]. This observation seems detrimental for any realistic prospect of creating van der Waals materials and heterostructures with atomically sharp interfaces. Here we employ cross sectional TEM to take a side view of several graphene-boron nitride heterostructures. We find that the trapped hydrocarbons segregate into isolated pockets, leaving the interfaces atomically clean. Moreover, we observe a clear correlation between interface roughness and the electronic quality of encapsulated graphene. This work proves the concept of heterostructures assembled with atomic layer precision and provides their first TEM images.

description: Supplementary dataset to: DNA metabardocing highlights cyanobacteria as the main source of primary production in a pelagic food web model. http://www.science.org/doi/10.1126/sciadv.adg1096

 Models that estimate rates of energy flow in complex food webs often fail to account for species-specific prey selectivity of diverse consumer guilds. While DNA metabarcoding is increasingly used for dietary studies, its application for food web modeling has been limited due to methodological biases. Here we used data from dietary metabarcoding studies of zooplankton to calculate prey selectivity indices and assess energy fluxes in a pelagic resource-consumer network. We show that food web dynamics are influenced by species prey selectivity and temporal match-mismatch in growth cycles and that cyanobacteria are the main source of primary production in the investigated coastal pelagic food web. The latter challenges the common assumption that cyanobacteria are not supporting food web productivity, a result that is increasingly relevant as global warming promotes cyanobacteria dominance. While this is the first time that DNA metabarcoding is used to quantify energy fluxes in a food web model, the approach presented here can easily be extended to other ecosystems.

description: There is a distinct possibility that current and future cosmological data can be used to constrain Einstein's theory of gravity on the very largest scales. To be able to do this in a model-independent way, it makes sense to work with a general parameterization of modified gravity. Such an approach would be analogous to the Parameterized Post-Newtonian (PPN) approach which is used on the scale of the Solar System. A few such parameterizations have been proposed and preliminary constraints have been obtained. We show that the majority of such parameterizations are only exactly applicable in the quasistatic regime. On larger scales they fail to encapsulate the full behaviour of typical models currently under consideration. We suggest that it may be possible to capture the additions to the `Parameterized Post-Friedmann' (PPF) formalism by treating them akin to fluid perturbations.

Agricultural nutrient management employing the concept of ecological goods and services : a valuation of ground water quality in Abbotsford, British Columbia
Creators: name: Ageson, Karen
Publisher: name: University of British Columbia
Year: 2011

description: There is an appetite for market based management mechanisms in agri-environmental policy. The purpose of this study is to explore how the market based concept of ecological goods and services (EGS) can be applied towards the management of an agricultural externality in British Columbia, Canada. Through literature review I establish the importance of valuation in market based management. With an EGS program in mind I identify the City of Abbotsford as a potential ecological service buyer and establish economic value for improvements to water quality in the Abbotsford-Sumas aquifer. I use a replacement cost approach based on the present value costs of the proposed Stave Lake surface water system. My results suggest that if nitrate remediation and/ or nitrate management practices improve water quality and the costs fall below $168 million there are potential net benefits to the City of Abbotsford. This value could form the basis for a city program or EGS trading scheme to encourage farmers to place a higher priority on water quality in their land management practices. A key finding is that lack of information on the degree to which nitrate contamination constrains well field development limits the ability to conclusively evaluate the net benefits of improved nitrate management and proceed with an EGS program.

Determining the polar cosmic ray effect on cloud microphysics and the Earth's ozone layer

description: Earth's changing climate is an important topic where atmospheric ozone plays a critical role. Ozone has a direct influence on the amount and type of solar radiation received by the Earth. This study addresses how cosmic rays may influence the ozone layer by ionizing Earth's atmosphere and enhancing the growth of cloud condensation nuclei and rate of chemical reactions on polar ice cloud surfaces. This theory was largely based on the lifetime work by Lu [2010]. The region of interest was centered over the Thule, Greenland neutron monitor station. Using cosmic ray, satellite-based ISCCP and ICARE project cloud data along with TOMS­OMI-SBUV and TEMIS total column ozone data, data comparisons were done. Plots of cosmic rays versus Antarctic atmospheric ozone from Lu [2009] were reproduced using regional Arctic data and extended to include years from 1983 to 2011. Comparisons to the research by Harris et al. [2010] were made by substituting ice cloud optical thickness for the cloud parameter and seasonal total column ozone for winter stratospheric ozone loss. The results of these data evaluations showed that the regional Arctic view matched very closely to Lu's work from the Antarctic. The ozone 3-point moving average case demonstrated a statistically significant correlation of -0.508. Extending the data duration exposed a cosmic ray data peak that was 14 percent larger than the two previous 11-year cycles. Ice cloud tau / ozone data comparisons did not produce the strong correlations from Harris et al. [2010]. Five years of low stratospheric temperatures and increased volumes of polar stratospheric clouds, identified by Rex et al. [2006], matched significant years of total column ozone minimums. Polar atmospheric CO2 trended along with ice cloud tau and oppositely to total column ozone, suggesting that lower stratospheric temperatures are instrumental in ozone reduction. Future work would involve using more extensive datasets, focusing on parameters such as ice water content and effective radius, or altitude specific studies concerning the stratosphere. Continued results from laboratory studies at the CERN facility may lead to a deeper understanding of cosmic ray, cloud microphysics and ozone relationships in nature.

description: Utah Prairie Dogs (Cymomys parvidens) have been listed, first as an endangered, then as a threatened species, under the Endangered Species Act since its inception in 1973. The species exists only in southern Utah, where approximately 75% of the land is managed by the Federal Government; however, it is estimated that 75% of the species' population occurs on private lands. Unfortunately, humans have had direct conflict with Utah prairie dogs since they first began agricultural practices in the area. We must find ways to create a benefit from Utah prairie dogs on private lands, in order to alleviate conflicts, to encourage species conservation, and to recover the species. One program, the Utah Prairie Dog Habitat Credit Exchange (HCE) has done just that. Created by a collaboration of experts working in wildlife biology, sociology, finance, and policy the HCE works with landowners to create conservation easement on parcels of their property where prairie dogs can do little harm. In return, landowners can manage prairie dogs elsewhere on their property AND receive monetary credit for their efforts. These credits are then sold to developers that need ‘take' for their property in order to develop their land. With this system, landowners have a bit of control over Utah prairie dogs on their land, get monetary compensation for protecting Utah prairie dogs on their land, the local towns have an avenue to continue to develop their land, and 'the ultimate goal' more Utah prairie dogs are protected across the landscape.

description: Bibliography: p. 141-147
description: Topological quivers generalize the notion of directed graphs in which the sets of ver­tices and edges are locally compact (second countable) Hausdorff spaces. Associated to a topological quiver Q is a C*-correspondence, and in turn, a Cuntz-Pimsner algebra C*(Q). Given r a locally compact group and a and (3 endomorphisms on r, one may construct a topological quiver Qae,,a(r) with vertex set r, and edge set n ,,8 (r) = { ( X ) y) E r X r I a(y) = (3( X)}. In this dissertation, the author examines the Cuntz-Pimsner algebra C* ( Q a,,B (r)). The investigative topics include generators of the C*-algebras, spatial structure (i.e., colimits, tensor products and crossed prod­ucts), K-groups, simplicity, and lattice properties.

description: Field-theoretical approach to Anderson localization in 2D disordered fermionic systems of chiral symmetry classes (BDI, AIII, CII) is developed. Important representatives of these symmetry classes are random hopping models on bipartite lattices at the band center. As was found by Gade and Wegner two decades ago within the sigma-model formalism, quantum interference effects in these classes are absent to all orders of perturbation theory. We demonstrate that the quantum localization effects emerge when the theory is treated non-perturbatively. Specifically, they are controlled by topological vortex-like excitations of the sigma models. We derive renormalization group equations including these non-perturbative contributions. Analyzing them, we find that the 2D disordered systems of chiral classes undergo a metal-insulator transition driven by topologically induced Anderson localization. We also show that the Wess-Zumino and Z_2 theta terms on surfaces of 3D topological insulators (in classes AIII and CII, respectively) overpower the vortex-induced localization.

The Anatomy of a Murder: Who Killed America's Economy?
Creators: name: Stiglitz, Joseph E.
Publisher: name: Columbia University
Year: 2009
Subjects: Economics

description: The main cause of the crisis was the behavior of the banks--largely a result of misguided incentives unrestrained by good regulation. Conservative ideology, along with unrealistic economic models of perfect information, perfect competition, and perfect markets, fostered lax regulation, and campaign contributions helped the political process along. The banks misjudged risk, wildly overleveraged, and paid their executives handsomely for being short-sighted; lax regulation let them get away with it--putting at risk the entire economy. The mortgage brokers neglected due diligence, since they would not bear the risk of default once their mortgages had been securitized and sold to others. Others can be blamed: the ratings agencies that judged subprime securities as investment grade; the Fed, which contributed low interest rates; the Bush administration, whose Iraq war and tax cuts for the rich made low interest rates necessary. But low interest rates can be a boon; it was the financial institutions that turned them into a bust.

description: This study aims to develop and implement a Strategic Facility Planning process at a highly regulated manufacturing site to optimise manufacturing space and capacity in a facility running out of space. The project demonstrates the application of Design for Lean Six Sigma and a structured Define, Measure, Analyse, Design, and Verify methodology in designing and implementing a process that enables the case study manufacturing site to improve its space utilisation and free up space. The project resulted in increased space usage of approx. 38000 sq. ft. equating to a hard cost saving of over $13 million for the organisation and a cost avoidance of $22 million. The study’s contribution is that it highlights for the first time that the Design for Lean Six Sigma methodology can be utilised for space and facility utilisation and can be leveraged by other manufacturers. This study has academic and managerial implications for identifying best practices for Design for Lean Six Sigma methodology application in Strategic facility planning. This study contributes to the few academic published works to utilise Design for Lean Six sigma methodology for space utilisation in a highly regulated environment. This study will contribute to managerial practice in aiding other manufacturing organisations with recommendations on utilising Design for Lean Six Sigma and design for improved space utilisation to reduce costs.
title: Visualizing Rhetorical Awareness: Building Critical Digital Literacies Practices With Visual Rhetoric in First-Year College Composition
Creators: name: Plaizier, Amanda J.
Publisher: name: Utah State University
Year: 2023

description: Visual rhetoric assignments allow students a space to practice rhetorical design with a specific audience in mind. When used in concordance with traditional writing assignments, these visual multimedia projects (such as flyers and infographics) can be a useful way for college writing teachers to build rhetorical awareness, which is one of the objectives of first-year college composition courses.
This project examines the use of visual rhetoric assignments within a concurrent enrollment college writing course. Students in the course created a community-based proposal, including flyers, infographics, and a final essay. By examining these assignments for evidence of critical digital literacies (decoding, meaning making, using, analyzing, and persona), the researchers investigated how the visual projects promoted student thinking about their audience in their designs and how composition teachers could use visual assignments, in combination with traditional writing assignments in college composition courses.
Measurement, modeling, and analysis of the file hosting ecosystem

description: Bibliography: p. 176-192
description: The Web has recently witnessed the emergence of file hosting services. These services provide users with a Web interface to upload, manage, and share files in the cloud. We present a comprehensive, longitudinal characterization study of the file hosting ecosystem. We perform detailed multi-level analysis of the usage behavior, infrastructure properties, content characteristics, and user-perceived performance of several top file hosting services. We instrument a measurement infrastructure that captures the characteristics of the ecosystem from multiple viewpoints across multiple layers. Our study utilizes multiple datasets collected over extended periods of time from passive measurements at an edge network, active measurement of an index site, as well as data collected through third-party Web analytics sources. Our two primary datasets are HTTP transaction and connection summaries of all Internet traffic collected at a large campus edge network over a one-year period. We carefully devised methods to identify user clickstreams in the HTTP transaction summary trace, including the identification of free and premium user instances, as well as the identification of content that is split into multiple pieces and downloaded using multiple transactions. We utilized the connection summary trace to understand and model salient flow-level and host-level properties of file hosting traffic. We augment our analysis with measurements from third-party analytics sources of global file hosting dynamics, as well as crawling file hosting links on an index site. Throughout this characterization, we compare and contrast these services with each other as well as with peer-to-peer file sharing and other media sharing services.

description: We consider finite range Gibbs fields and provide a purely combinatorial proof of the exponential tree decay of semi--invariants, supposing that the logarithm of the partition function can be expressed as a sum of suitable local functions of the boundary conditions. This hypothesis holds for completely analytical Gibbs fields; in this context the tree decay of semi--invariants has been proven via analyticity arguments. However the combinatorial proof given here can be applied also to the more complicated case of disordered systems in the so called Griffiths' phase when analyticity arguments fail.
The Mughal Book of War: A Persian Translation of the Sanskrit Mahabharata

Year: 2011
Subjects: South Asians

description: This article presents the first in-depth textual analysis of the Razmnamah (Book of War), the Persian translation of the Mahabharata sponsored by the Mughal emperor Akbar in the late sixteenth century. I argue that the Razmnamah was a central literary work in the Mughal court and of deep relevance to Akbar's imperial and political ambitions. I pursue my analysis of the Mughal Mahabharata in two sections, focusing first on the work's Sanskrit sources and then on the translation practices one finds evidenced in the Persian text. In the first section, I outline how the Mughal translators accessed Sanskrit materials and identify the Sanskrit texts that served as the basis for the Persian translation. This framework helps reconstruct the nature of the Mahabharata as the Mughals knew it and provides both the conceptual and literary tools needed to pursue comparative textual analysis. In the second section, I examine the text of the Razmnamah in comparison with its Sanskrit sources to highlight some of the Mughal translators' key strategies in reimagining the epic in Persian. This close reading traces several literary paradigms that offer insight into the crucial role the Razmnamah played in the production and reproduction of Mughal imperial culture. Taken as a whole, my analysis argues that the Razmnamah was a crucial component of the politico-cultural fashioning of Akbar's court, whereby the Mughals developed a new type of Indo-Persian imperial aesthetic.

description: Cyclooxygenase (COX) is an enzyme which functions to break down arachidonic acid (AA) into prostaglandins (PGs) which mediate numerous physiological processes. COX is expressed throughout all of the major organs including the brain, heart, lungs, uterus and kidney as well as smooth muscle vasculature. The two different COX isoforms, COX-1 and COX-2, are present in the kidney and have an important role in maintaining renal hemodynamics and function. The production of PGs through enzymatic activity of COX is prevented with the use of non-steroidal anti-inflammatory drugs (NSAIDs), which non-selectively inhibit the activity of both COX isoforms. Currently, NSAIDs may be administered to pregnant women to inhibit premature labor, as well as to preterm infants to aid in the closure of a patent ductus arteriosus (PDA). Inhibition of PGs in the fetal and newborn kidney may result in deleterious effects on kidney function including acute kidney injury in the newborn period. The mechanism(s) underlying the adverse effects of non-selective COX inhibition on the newborn kidney is not known. The objective of this investigation is to describe for the first time, mRNA and protein expression of COX-1 and COX-2 isoforms in both the cortical and medullary regions from birth through three months of age in the ovine kidney. To assess COX expression, ovine kidney tissue from cortex and medulla of lambs from five postnatal ages (N=3 from each age group), were examined. Reverse transcriptase polymerase chain reaction (RT-PCR) analysis was employed to assess mRNA expression and Western blot assays were utilized to determine the expression of protein for COX-1 and COX-2 within the ovine kidney. Results from these investigations provide, for the first time, a profile of COX-I and COX-2 expression at the level of mRNA and protein, comparing cortex and medulla within the ovine kidney over five ages in early postnatal life. The expression of COX isoforms in cortical and medullary regions of the developing kidney throughout the first three months of postnatal life may help us to understand the mechanisms by which COX inhibition may influence growth and function of the mammalian kidney.

description: We provide a simple analytic formula for the two-loop six-point ratio function of planar N = 4 super Yang-Mills theory. This result extends the analytic knowledge of multi-loop six-point amplitudes beyond those with maximal helicity violation. We make a natural ansatz for the symbols of the relevant functions appearing in the two-loop amplitude, and impose various consistency conditions, including symmetry, the absence of spurious poles, the correct collinear behaviour, and agreement with the operator product expansion for light-like (super) Wilson loops. This information reduces the ansatz to a small number of relatively simple functions. In order to fix these parameters uniquely, we utilize an explicit representation of the amplitude in terms of loop integrals that can be evaluated analytically in various kinematic limits. The final compact analytic result is expressed in terms of classical polylogarithms, whose arguments are rational functions of the dual conformal cross-ratios, plus precisely two functions that are not of this type. One of the functions, the loop integral Ω^{(2)}, also plays a key role in a new representation of the remainder function R_6^{(2)} in the maximally helicity violating sector. Another interesting feature at two loops is the appearance of a new (parity odd) \times (parity odd) sector of the amplitude, which is absent at one loop, and which is uniquely determined in a natural way in terms of the more familiar (parity even) \times (parity even) part. The second non-polylogarithmic function, the loop integral \tildeΩ^{(2)}, characterizes this sector. Both Ω^{(2)} and tildeΩ^{(2)} can be expressed as one-dimensional integrals over classical polylogarithms with rational arguments.

Measurement error in linear mixed models

description: Measurement error of exposure is widely acknowledged as pervasive and often important source of bias or misleading results in much research. There has been an abundance of interest in the topic of covariate measurement error and there is an extensive literature in measurement error models and methods. Clustered data can be defined as data in which the observations are grouped into disjoint classes, called clusters, according to some classification criterion. Mixed models were developed to handle clustered data and have received a great deal of attention in the statistical literature for the past years because of the flexibility they offer in handling the unbalanced clustered data that arise in many areas of investigation. In this thesis we consider both linear and linear mixed effect models with measure­ment error. Three methods are compared through simulation studies, namely the naive method, the two-step approach, and the likelihood estimation method. The naive method ignores covariate measurement error in models, the regression calibration method, as a two-step approach, is a commonly used simple approach and may be applicable to al­most any regression models, and the Expectation Maximization (EM) algorithm, as a likelihood method, treats random effects as missing data. Naive approaches are shown to be inadequate to be used when covariates are subject to error. Both the regression calibration method and the EM method appear to be good, but the regression calibration method is much simpler than the EM method. We illustrate these methods in HIV study data.

description: Intra-cellular biochemical reactions exhibit a rich dynamical phenomenology which cannot be explained within the framework of mean-field rate equations and additive noise. Here, we show that the presence of metastable states and radically different timescales are general features of a broad class of autocatalyic reaction networks, and moreover, that this fact may be exploited to gain analytical results. The latter point is demonstrated by a treatment of the paradigmatic Togashi-Kaneko reaction, which has resisted theoretical analysis for the last decade.
