Learning to Meet the 'Demands of the Day': Towards a Weberian Philosophy of Education
Creators: Fantuzzo, John Peter

Education--Philosophy

description: The purpose of this dissertation is to propose a Weberian philosophy of education. I understand philosophy of education to be a field dedicated to reflection upon the educator’s practice. My project arises from the contention that too many contemporary philosophers of education have, in the name of realism, exchanged reflection on educational practice for reflection on the political dimensions of educational institutions, thereby engaging in some variety of applied political philosophy. Treating philosophy of education as applied political philosophy demotes the significance of educational practice and thus the significance of the field itself. The central question this dissertation takes up is how philosophers of education might lend significance and priority to educational practice in a manner that does not ignore the realities of educational institutions. My argument is that a Weberian philosophy of education – a philosophy based on social theorist Max Weber’s conception of education – can provoke reflection upon the ideal qualities of educational practice amidst a non-ideal and pluralistic society. A Weberian philosophy of education revives a vision of students as particular persons, prioritizes calling as an educational aim, galvanizes the dignity of the educator’s cause, and points towards the responsible re-enchantment of society.
Prediction of acid rock drainage : Red Mountain Project, northwestern British Columbia

description: A kinetic ARD prediction program was conducted for the Red Mountain project, located in northwest British Columbia, to provide the operators with more precise prediction data and thereby allow for a more cost effective and confident development of the waste management plan. Kinetic tests such as humidity cells are widely used in an attempt to predict the rates of acid generation and neutralization, water quality and time to onset of acidity. Laboratory kinetic tests at the University of British Columbia evaluated the effects of testing under various conditions. The laboratory test results were compared to 20-tonne (field) test results to evaluate scaling up of laboratory data. Test results indicate that non-aerated cells provide rates of weathering that are similar to the standard humidity cell and that the results are more repeatable than humidity cell results. The laboratory rates of weathering could not be scaled up to predict field results with confidence. The inability to scale up the results is believed to be caused by inadequate hydrogeological assumptions and deficiencies in the experimental protocols.

description: Tamm polaritons (TPs) are formed at the interface between two semi-infinite periodic dielectric structures (Bragg mirrors) or other reflectors. Contrary to usual surface polaritons, TPs exist inside the "light cone", even though their amplitude also decreases exponentially with the distance from the interface as it is characteristic of evanescent waves. They couple to elementary excitations in the materials or structures that form the interface, such as metal plasmons or semiconductor excitons. Here we discuss the formation of TPs in the far-infrared (FIR) spectral range, in the optical-phonon reststrahlen band of a polar semiconductor such as GaAs, with a Bragg reflector (BR) as the second mirror. Their dispersion relation and the frequency window for the TP existence are discussed for a GaAs-BR interface. Structures containing a gap between the two reflectors are also considered. Further investigation is performed on a structure containing a layer of graphene between the two reflectors.

description: It has recently been found that supernova explosions can be simulated in the laboratory by implosions induced in a plasma by intense lasers. A theoretical explanation is that the inversion transformation, ($Σ: t \to -1/t,~ {\bf x}\to {\bf x}/t$), leaves the Euler equations of fluid dynamics, with standard polytropic exponent, invariant. This implies that the kinematical invariance group of the Euler equations is larger than the Galilei group. In this paper we determine, in a systematic manner, the maximal invariance group ${\cal G}$ of general fluid dynamics and show that it is a semi-direct product ${\cal G} = SL(2,R) \wedge G$, where the $SL(2,R)$ group contains the time-translations, dilations and the inversion $Σ$, and $G$ is the static (nine-parameter) Galilei group. A subtle aspect of the inclusion of viscosity fields is discussed and it is shown that the Navier-Stokes assumption of constant viscosity breaks the $SL(2, R)$ group to a two-parameter group of time translations and dilations in a tensorial way. The 12-parameter group ${\cal G}$ is also known to be the maximal invariance group of the free Schrödinger equation. It originates in the free Hamilton-Jacobi equation which is central to both fluid dynamics and the Schrödinger equation.

Impact of contaminated sites legislation on closure of an acid generating mine site in British Columbia

Publisher: name: The University of British Columbia
Year: 2009

description: In the past few years, numerous mine closure and reclamation projects have been subjected to the provincial Contaminated Sites Regulation (CSR) in British Columbia. A mine decommissioning and closure plan should contain among other things a Detailed Site Investigation report, a Remedial Action Plan and the necessary financial security to ensure funds are available to carry out the remediation work. The intent of the CSR has been to facilitate the complete sign off of long-term environmental liability to a company by government from a particular site through requiring a company to meet all the requirements defined in the regulation. This sign off can be in the form of a Certificate of Compliance, Conditional Certificate of Compliance or Letter of Comfort. Contaminated Sites Regulations have been developed predominantly for industrial or commercial sites usually in an urban environment with clearly defined contaminants associated with the particular industry. Problems associated with acid rock drainage and acid generating sulphide waste contamination are not clearly defined in these regulations. Complications arise when applying the CSR to the mining sector. In particular, the interpretation of a regulation which defines "contaminated site" based on concentrations of naturally occurring inorganic substances (metals) in soil and groundwater In addition, the CSR bureaucratic process has not been generally structured to blend with more traditional mine closure plans required under the Mines Act even though the regulations are somewhat linked. While the intent of government has been to link and harmonize the CSR with the mine closure regulations, in BC, the harmonization of the regulations and various ministries has yet to be tested fully and it is anticipated will require modification to the regulations. This paper will give an overview of the environmental regulatory context in British Columbia with particular reference to CSR requirements at acid generating mine sites. In addition, technical and administrative requirements will be given together with a discussion of the impacts of these regulations on the mining industry and ways to plan and manage associated liabilities.

description: A watching brief undertaken when the tower of Holy Trinity Church, Basham, was repaired in 1988 revealed that the Anglo Saxon tower of this important, former minster, church, which may originally have been a two stage west annexe, survives intact from plinth level to corbelled eaves course though it has been altered and repaired on several occasions. Soon after the Conquest the tower was heightened by the addition of a new belfry stage which included at least two windows and a finely carved corbelled eaves course. Later alterations include the rebuilding of the south-west quoin at an as yet unknown date, the insertion of three new windows in the belfry and the erection of the present spire probably in the 15th century.

description: Magnetic resonance spectroscopy (MRS) allows for assessment of tissue metabolite characteristics used often for early detection and treatment evaluation of brain-related pathologies. However, a steep learning curve for metabolite interpretation, paired with limited visualization tools, have constrained the more widespread adoption of MRS in clinical practice. In this design study, we collaborated with domain experts to design a novel visualization tool for the exploration of tissue metabolite concentration ratios in MRS clinical and research studies. We present a data and task analysis for this domain, with categorization of MRS data attributes into tiers of visual priority. We furthermore introduce a novel set of visual encodings for these attributes. Our result is SpectraMosaic (Figure 1), an interactive insight-generation tool for rapid exploration and comparison of metabolite ratios. We validate our approach with two case studies from MR spectroscopy experts, providing early qualitative evidence of the efficacy of the system and affording deeper insights into these complex data.

description: Generative adversarial networks have been shown to alleviate the problem of limited training data for supervised learning problems in medical image computing. However, most generative models for medical images focus on image-to-image translation rather than de novo image synthesis. In many clinical applications, image acquisition is multiparametric, i.e. includes contrast-enchanced or diffusion-weighted imaging. We present a generative adversarial network that synthesizes a sequence of temporally consistent contrast-enhanced breast MR image patches. Performance is evaluated quantitatively using the Fréchet Inception Distance, achieving a minimum FID of 21.03. Moreover, a qualitative human reader test shows that even a radiologist cannot differentiate between real and fake images easily.

description: We present an external interferometric setup that is able to simultaneously acquire three wavelengths of the same sample instance without scanning or multiple exposures. This setup projects onto the monochrome digital camera three off-axis holograms with rotated fringe orientations, each from a different wavelength channel, without overlap in the spatial-frequency domain, and thus allows the full reconstruction of the three complex wavefronts from the three wavelength channels. We use this new setup for three-wavelength phase unwrapping, allowing phase imaging of thicker objects than possible with a single wavelength, but without the increased level of noise. We demonstrate the proposed technique for micro-channel profiling and label-free cell imaging.

description: In this thesis, we consider how service platforms can provide personalized service to incoming consumers in order to improve ease and convenience for their users, or to enhance their own revenues. With an increasing trend toward digitalization, there is now a massive amount of data that can be leveraged to accomplish this goal. In this thesis, we explore how to leverage feature data about the consumers and products, as well as the way consumers interact with the platforms, in order to make better operational decisions, such as pricing, ranking, and recommendations of products and services. In Chapters 1 & 2, we study platforms in which consumers' purchasing decisions are strongly influenced by reviews that are posted by previous consumers. In Chapter 1, we consider how a platform can learn from the choices that consumers make, as well as the reviews they leave, in order to form increasingly accurate estimates about product quality and consumer preferences, so that the platform can provide better personalized product rankings. In Chapter 2, we focus on platforms where each consumer forms an impression of a product by browsing the available reviews in a chosen order following a cascade click model. We consider how to rank the reviews as well as how to price a product given the reviews, in order to maximize short- and long-term revenue. In Chapter 3, we study a platform that offers a menu of memberships of different durations to a pool of heterogeneous consumers. A consumer's choice depends on both the menu prices and his personal intended usage time. The platform wants to maximize the long-term revenue while considering the choices made by heterogeneous customers. We show insights into the optimal solution of each problem when all the parameters are known. For the case where some parameters are initially unknown, we propose a joint learning and optimization algorithm, and provide theoretical guarantees for its performance.

description: The analysis of the morphology and content of the gut is necessary in order to achieve a better understanding of its metabolic and functional activity. Magnetic resonance imaging (MRI) has become an important imaging technique since it is able to visualize soft tissues in an undisturbed bowel using no ionizing radiation. In the last few years, MRI of gastrointestinal function has advanced substantially. However, few studies have focused on the colon, because the analysis of colonic content is time consuming and cumbersome. This paper presents a semi-automatic segmentation tool for the quantitative assessment of the unprepared colon from MRI images. The techniques developed here have been crucial for a number of clinical experiments.

Multi-velocity and multi-temperature model of the mixture of polyatomic gases issuing from kinetic theory

Year: 2019
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: In this paper, we consider Euler-like balance laws for mixture components that involve macroscopic velocities and temperatures for each different species. These laws are not conservative due to mutual interaction between species. In particular, source terms that describe the rate of change of momentum and energy of the constituents appear. These source terms are computed with the help of kinetic theory for mixtures of polyatomic gases. Moreover, if we restrict the attention to processes which occur in the neighborhood of the average velocity and temperature of the mixture, the phenomenological coefficients of extended thermodynamics can be determined from the computed source terms.
Learning with Degree-Based Subgraph Estimation
Creators: Huang, Bert
Publisher: name: Columbia University
Year: 2011
Subjects: Computer science

description: Networks and their topologies are critical to nearly every aspect of modern life, with social networks governing human interactions and computer networks governing global information-flow. Network behavior is inherently structural, and thus modeling data from networks benefits from explicitly modeling structure. This thesis covers methods for and analysis of machine learning from network data while explicitly modeling one important measure of structure: degree. Central to this work is a procedure for exact maximum likelihood estimation of a distribution over graph structure, where the distribution factorizes into edge-likelihoods for each pair of nodes and degree-likelihoods for each node. This thesis provides a novel method for exact estimation of the maximum likelihood edge structure under the distribution. The algorithm solves the optimization by constructing an augmented graph containing, in addition to the original nodes, auxiliary nodes whose edges encode the degree potentials. The exact solution is then recoverable by finding the maximum weight b-matching on the augmented graph, a well-studied combinatorial optimization. To solve the combinatorial optimization, this thesis focuses in particular on a belief propagation-based approach to finding the optimal b-matching and provides a novel proof of convergence for belief propagation on the loopy graphical model representing the b-matching objective. Additionally, this thesis describes new algorithmic techniques to improve the scalability of the b-matching solver. In addition to various applications of node degree in machine learning, including classification and collaborative filtering, this thesis proposes a learning algorithm for learning the parameters of the distribution from network data consisting of node attributes and network connectivity, using strategies similar to maximum-margin structured prediction. The main methods and results in this thesis represent a deep exploration of exact degree-based estimation for machine learning from network data, and furthermore lead to various extensions and applications of the main idea described within.

description: The colon is an organ whose constant motility poses difficulties to its analysis. Although morphological data can be successfully extracted from Computational Tomography, its radiative nature makes it only indicated for patients with disorders. Only recently, acquisition techniques that rely on the use of Magnetic Resonance Imaging have matured enough to enable the generation of morphological colon data of healthy patients without preparation (i. e. administration of drugs or contrast agents). As a result, a database of colon morphological data for patients under different diets, has been created. Currently, the digestologists we collaborate with analyze the measured data of the gut by inspecting a set of spreadsheets. In this paper, we propose a system for the exploratory visual analysis of the whole database of morphological data at once. It provides features for the visual comparison of data correlations, the inspection of the morphological measures, as well 3D rendering of the colon segmented models. The system solely relies on the use of web technologies, which makes it portable even to mobile devices.

description: When Diffusion Tensor Imaging (DTI) is used in clinical studies, statistical hypothesis testing is the standard approach to establish significant differences between groups, such as patients and healthy controls. However, diffusion tensors contain six degrees of freedom, and the most commonly used univariate tests reduce them to a single scalar, such as Fractional Anisotropy. Multivariate tests that account for the full tensor information have been developed, but have not been widely adopted in practice. Based on analyzing the limitations of existing univariate and multivariate tests, we argue that it is beneficial to use a more flexible, steerable test. Therefore, we introduce a test that can be customized to include any subset of tensor attributes that are relevant to the analysis task at hand. We also present a visual analytics system that supports the exploratory task of customizing it to a specific scenario. Our system closely integrates quantitative analysis with suitable visualizations. It links spatial and abstract views to reveal clusters of strong differences, to relate them to the affected anatomical structures, and to visually compare the results of different tests. A use case is presented in which our system leads to the formation of several new hypotheses about the effects of systemic lupus erythematosus on water diffusion in the brain.

Learning-by-Doing and Its Implications for Economic Growth and International Trade

description: By adding physical capital as a factor of production, and by introducing capital accumulation and population growth, I generalized the model of learning-by-doing proposed by Young (1991). Under this extended model, I studied the evolution of human capital formulated by learning-by-doing, its effects on long run growth and intertemporal welfare, the dynamic effects of trade between two countries with different initial stocks of knowledge, and the effects of saving rate and population growth rate of each country. In addition to confirming Young's original conclusion that the country with less (more) initial stock of knowledge enjoys lower (higher) or the same growth rates of technical progress and per capita GDP than those enjoyed under autarky, I have shown that the learning-by-doing progress is the source of long-run sustainable growth, both of which exhibit higher rates of growth with an increase in the country's saving rate or population growth rate. In addition, the dynamic behaviors of both countries' intertemporal welfare, as well as their relationships with both countries' saving rates and population growth rates have also been discussed in detail.

description: The Bazanski approach, for deriving the geodesic equations in Riemannian geometry, is generalized in the absolute parallelism geometry. As a consequence of this generalization three path equations are obtained. A striking feature in the derived equations is the appearance of a torsion term with a numerical coefficients that jumps by a step of one half from equation to another. This is tempting to speculate that the paths in absolute parallelism geometry might admit a quantum feature.

These coordinates arise from a generalisation of Kra's plumbing construction and are related to earthquakes on Teichmueller space. They also allow us to interpolate between two coordinate systems on Teichmueller space, namely the classical Fuchsian space with Fenchel-Nielsen coordinates and the Maskit embedding. We also show how they relate to the pleating coordinates of Keen and Series.

description: Brain MR images are one of the most important instruments for diagnosing neurological disorders such as tumors, infections or trauma. In particular, grade I-IV brain tumors are a well-studied subject for supervised deep learning approaches. However, for a clinical use of these approaches, a very large annotated database that covers all of the occurring variance is necessary. As MR scanners are not quantitative, it is unclear how good supervised approaches, trained on a specific database, will actually perform on a new set of images that may stem from a yet other scanner. We propose a new method for brain tumor segmentation, that can not only identify abnormal regions, but can also delineate brain tumors into three characteristic radiological areas: The edema, the enhancing core, and the non-enhancing and necrotic tissue. Our concept is based on FLAIR and T1CE MRI sequences, where abnormalities are detected with a variational autoencoder trained on healthy examples. The detected areas are finally postprocessed via Gaussian Mixture Models and finally classified according to the three defined labels. We show results on the BraTS2018 dataset and compare these to previously published unsupervised segmentation results as well as to the results of the BraTS challenge 2018. Our developed unsupervised anomaly detection approach is on par with previously published methods. Meanwhile, the semantic segmentation - a new and unique model - shows encouraging results.

Feasibility Study For Automatic Bird Tracking and Visualization from Time-Dependent Marine Radar Imagery
Creators: name: Ganglberger, Florian

description: In recent years, radar technology has increasingly been used for the monitoring of bird migration. Marine radars are often utilized for this purpose because of their wide accessibility, range, and resolution. They allow the tracking of birds even at night-when most bird migration takes place-over extended periods of time. This creates a wealth of radar images, for which manual annotation of bird tracks is not feasible. We propose a tool for automatic bird tracking and visualization from marine radar imagery. For this purpose, we developed a bird tracking algorithm for vertically recorded radar images that is able to extract quantitative parameters including flight direction, height, and duration. The results can be qualitatively verified by a visualization design that enables domain experts the time-dependent visualization of bird tracks. Furthermore, it allows a preprocessing of radar images taken by screen capturing for device independence. Our tool was used in an ornithological monitoring study to analyze over 200.000 vertically recorded radar images taken in multiple observation periods and locations.

Learning with Waka Poetry: Transmission and Production of Social Knowledge and Cultural Memory in Premodern Japan

description: This dissertation argues that throughout premodern Japan, classical Japanese poetry (waka) served as a vehicle for the transmission of social knowledge, cultural memory, and specialized information. Waka was originally indispensable to private and public social interactions among aristocrats, but it came to play a diversity of functions for warriors, monks, farmers, merchants, and other social groups at each and every level of premodern society and over many centuries, particularly from the late Heian period (785-1185) through the Edo period (1600-1868). To trace the changes in the social functions of waka, this dissertation explores several moments in the history of waka: the development of a pedagogy for waka in the poetic treatises of the Heian period; the reception of these works in anecdotal collections of the Kamakura period (1192-1333), particularly those geared towards warriors; the use of humorous waka (kyôka), in particular those with satiric and parodic intent, in Muromachi-period (1333-1467) narratives for commoners; and the use of waka as pedagogical instruments for the codification, preservation, transmission, and memorization of knowledge about disciplines as diverse as hawking, kickball, and the tea ceremony. In the epilogue, I trace the efforts of Meiji-period (1868-1911) intellectuals who sought to disconnect waka from any social or pedagogical function, in order to reconceptualize it under the modern European notions of “Literature” and “the Arts.” I conclude that the social functions of poetry in the premodern period should not be understood as extra-literary uses of poems that were otherwise composed as purely literary works in the modern sense. The roles that waka played in pedagogy, in particular in the transmission of cultural memory and social knowledge across diverse social spaces, were an inherent feature of the practice of waka in premodern Japan.

Material examined. 1♂ [Figure 3C], Colombia, Co ́ rdoba, Tierralta: TuisTuis, [8°2'2.881"N, 76°5'29.993"W], [178m], 3 Dec 2014, humid forest, manual collection, E. Bedoya – Roqueme leg. (LEUC; OARA-096). Type material in the MACN, MNHN not examined.
 Diagnosis. According to Ruiz & Brescovit (2008), the male H. albovittata (Figure 3C) is easily distinguished from other Helvetia species by the very long embolus, the form of the RTA and the presence of a depression on the retrolateral cymbium where the tip of the embolus is held in resting position (see Bedoya-Roqueme et al. 2018, figs. 6-11).
 Natural history. The habitats of this species appear to be very diverse. The specimens of H. albovittata from Colombia have been found in mangrove forests and humid forests. Here we report a male from humid forest.
 Distribution. Argentina, Brazil, Colombia, Galapagos Islands, Netherlands Antilles, Paraguay.

description: We present an interactive visual environment for linked analysis of brain imaging and clinical measurements. The environment is developed in an iterative participatory design process involving neuroscientists investigating the causes of brain-related complex diseases. The hypotheses formation process about correlations between active brain regions and physiological or psychological factors in studies with hundreds of subjects is a central part of the investigation. Observing the reasoning patterns during hypotheses formation, we concluded that while existing tools provide powerful analysis options, they lack effective interactive exploration, thus limiting the scientific scope and preventing extraction of knowledge from available data. Based on these observations, we designed methods that support neuroscientists by integrating their existing statistical analysis of multivariate subject data with interactive visual exploration to enable them to better understand differences between patient groups and the complex bidirectional interplay between clinical measurement and the brain. These exploration concepts enable neuroscientists, for the first time during their investigations, to interactively move between and reason about questions such as 'which clinical measurements are correlated with a specific brain region?' or 'are there differences in brain activity between depressed young and old subjects?'. The environment uses parallel coordinates for effective overview and selection of subject groups, Welch's t-test to filter out brain regions with statistically significant differences, and multiple visualizations of Pearson correlations between brain regions and clinical parameters to facilitate correlation analysis. A qualitative user study was performed with three neuroscientists from different domains. The study shows that the developed environment supports simultaneous analysis of more parameters, provides rapid pathways to insights, and is an effective support tool for hypothesis formation.

Does backreaction enforce the averaged null energy condition in semiclassical gravity?

description: The expected stress-energy tensor of quantum fields generically violates the local positive energy conditions of general relativity. However, may satisfy some nonlocal conditions such as the averaged null energy condition (ANEC), which would rule out traversable wormholes. Although ANEC holds in Minkowski spacetime, it can be violated in curved spacetimes if one is allowed to choose the spacetime and quantum state arbitrarily, without imposition of the semiclassical Einstein equation G_{ab} = 8 π. In this paper we investigate whether ANEC holds for solutions to this equation, by studying a free, massless scalar field with arbitrary curvature coupling in perturbation theory to second order about the flat spacetime/vacuum solution. We "reduce the order" of the perturbation equations to eliminate spurious solutions, and consider the limit in which the lengthscales determined by the incoming state are much larger than the Planck length. We also need to assume that incoming classical gravitational radiation does not dominate the first order metric perturbation. We find that although the ANEC integral can be negative, if we average the ANEC integral transverse to the geodesic with a suitable Planck scale smearing function, then a strictly positive result is obtained in all cases except for the flat spacetime/vacuum solution. This result suggests --- in agreement with conclusions drawn by Ford and Roman from entirely independent arguments --- that if traversable wormholes do exist as solutions to the semiclassical equations, they cannot be macroscopic but must be ``Planck scale''. A large portion of our paper is devoted to the analysis of general issues concerning the nature of the semiclassical Einstein equation and of prescriptions for extracting physically relevant solutions.
