description: Environmental self-auditing by private firms is generally thought to both deserve and require encouragement. Firms can audit themselves more cheaply and effectively than can regulators, but too often are deterred for fear that the information they uncover will be used against them. To reduce this disincentive, the EPA's "Audit Policy" lowers punitive fines when firms promptly disclose and correct violations that they themselves discover. While some contend that the Audit Policy is inadequate, EPA touts its success, presenting as evidence the policy's track record to date. Yet our examination of that track record leads us to question EPA's conclusions. While the policy appears to have encouraged firms to self-audit in a number of instances, a comparison of the violations uncovered in these cases with those detected by standard enforcement practices suggests that the typical self-audited violation is relatively minor. For instance, cases arising under the Audit Policy are more likely to concern reporting violations, rather than emissions. The relative insignificance of self-audited violations raises a number of broader policy questions, including whether the Audit Policy could and should be revised to play a larger role in regulatory enforcement.

description: Nominal abstract syntax is an approach to representing names and binding pioneered by Gabbay and Pitts. So far nominal techniques have mostly been studied using classical logic or model theory, not type theory. Nominal extensions to simple, dependent and ML-like polymorphic languages have been studied, but decidability and normalization results have only been established for simple nominal type theories. We present a LF-style dependent type theory extended with name-abstraction types, prove soundness and decidability of beta-eta-equivalence checking, discuss adequacy and canonical forms via an example, and discuss extensions such as dependently-typed recursion and induction principles.
Rethinking Schools : school design and students' relationships with the natural world
Creators: name: Dutt, Indira
Publisher: name: University of British Columbia
Year: 2011

description: This thesis asks how are intermediate students’ relationships with the natural world mediated by the design of their school building? This question is explored by looking at students’ responses to two design features of their school building: the relationship of the school building to the school site and indoor/outdoor interfaces. In addition, students’ ideas about hypothetical school buildings that foster a relationship with nature were also investigated. The fieldwork for this project was conducted in the spring of 2009 at Bowen Island Community School, which is part of the West Vancouver School District, and located on Bowen Island, B.C. Data was collected from two focus groups using arts based inquiry as well as five semi-structured interviews, photographs and fieldnotes. Using thematic analysis, the research found that nearby nature and the presence of indoor/outdoor interfaces provided students with a sense of freedom, joy, social cohesiveness and aesthetic pleasure. In addition participants had valuable design ideas for creating a strong connection between students and the natural world at school. Results are discussed in terms of future school design and student impact.

description: It has been claimed in a recent paper \cite{bbfhd12} that sudden singularities will survive in semiclassical gravity. This issue is here carefully reviewed, pointing out that such conclusion, even if valid under some specific conditions, does not stand in other cases. An explicit example is studied in detail to support our statement, stemming from these other situations, that quantum effects may in fact drastically modify the behavior of sudden singularities.

Democracy, governance and economic growth: Theory and evidence
Creators: name: Rivera-Batiz, Francisco
Publisher: name: Columbia University
Year: 2002
Subjects: Economics

description: This paper examines how democracy affects long-run growth by influencing the quality of governance. Empirical evidence is presented first showing that measures of the quality of governance are substantially higher in more democratic countries. A general equilibrium, endogenous growth model is then built to show how a governance improving democracy raises growth. In this model, stronger democratic institutions influence governance by constraining the actions of corrupt officials. Reducing corruption, in turn, stimulates technological change and spurs economic growth. Empirical evidence is presented showing that democracy is in fact a significant determinant of total factor productivity (TFP) growth between 1960 and 1990 in a cross-section of countries. But this contribution occurs only insofar as stronger democratic institutions are associated with greater quality of governance.

description: Learning is a cognitive process of knowledge and behavior acquisition for both humans and machines. Cognitive machine learning systems are increasingly demanded in modern knowledge-based industry, society, and everyday lives. This study on theories and applications of cognitive machine learning based on denotational mathematics is designed to develop methodologies, algorithms, and their implementations for machine enabled knowledge learning at the conceptual, phrasal, and sentence levels via cognitive computing technologies. The main objectives of this work are: a) To develop a cognitive and mathematics-based machine learning theory for knowledge acquisition and semantic manipulations; b) To enable machines to autonomously learn and understand semantics expressed in natural languages underpinned by unsupervised cognitive computing algorithms; and c) To design and implement a brain-inspired cognitive learning engine for inductively learning from the level of formal concepts to those of phrases and sentences. The thesis is embodied by three novel and autonomous machine knowledge learning algorithms underpinned by Wang’s denotational mathematics. In this research, properties of formal concepts and mathematical rules of concept algebra are formally studied. A method for building quantitative semantic hierarchies of formal concepts is implemented by cognitive machine learning. Theories and mathematical models for an unsupervised algorithm of phrase learning are developed based on rigorous concept comprehensions by cognitive machine learning. A machine knowledge learning system for sentence syntactic analysis and semantic synthesis is developed and implemented by novel cognitive computing technologies. This thesis does not only present a set of basic studies on machine learning challenges in the sixth category of knowledge learning and semantic comprehension, but also implement efficient cognitive machine learning systems mimicking human learning. This research will enable a wide range of industrial applications such as cognitive robotics, natural language comprehension systems, personal leaning assistants, cognitive search engines, and language translators.

description: This thesis presents a framework of studies on theories, methodologies, algorithms, and experiments on cognitive knowledge bases (CKBs) for machine knowledge learning in cognitive computing and computational linguistics. CKB is both the results and the means of machine learning methodologies mimicking human learning and semantic comprehensions. Technologies for machine learning can be classified into six categories according to Dr. Y. Wang known as object identification, cluster classification, pattern recognition, functional regression, behavior generation, and knowledge acquisition. Most current machine learning techniques fall into the first five categories. However, the sixth category of knowledge learning as humans do has remained as a fundamental problem and challenge in machine learning, AI, and computational intelligence. A set of algorithms, tools, and experiments on machine knowledge learning is designed in order to demonstrate that cognitive machines may create their own concepts and CKBs through knowledge learning. The accuracy and cohesiveness of machine learnt results may outperform humans. This leads to the implementation of formal knowledge comprehension and quantitative semantic analyses by cognitive systems based on CKBs and machine semantic comprehensions. The theoretical framework and case studies derived from this research will impact the field of machine knowledge learning technologies and the development of novel cognitive systems. This research will enable industrial applications such as personal leaning assistants, cognitive search engines, and cognitive translators.
Globalization and monetary control

description: It has recently become popular to argue that globalization has had or will soon have dramatic consequences for the nature of the monetary transmission mechanism, and it is sometimes suggested that this could threaten the ability of national central banks to control inflation within their borders, at least in the absence of coordination of policy with other central banks. In this paper, I consider three possible mechanisms through which it might be feared that globalization can undermine the ability of monetary policy to control inflation: by making liquidity premia a function of "global liquidity" rather than the supply of liquidity by a national central bank alone; by making real interest rates dependent on the global balance between saving and investment rather than the balance in one country alone; or by making inflationary pressure a function of "global slack" rather than a domestic output gap alone. These three fears relate to potential changes in the form of the three structural equations of a basic model of the monetary transmission mechanism: the LM equation, the IS equation, and the AS equation respectively. I review the consequences of global integration of financial markets, final goods markets, and factor markets for the form of each of these parts of the monetary transmission mechanism, and find that globalization, even of a much more thorough sort than has yet occurred, is unlikely to weaken the ability of national central banks to control the dynamics of inflation.
Ideal MHD Ballooning modes, shear flow and the stable continuum
Creators: name: Taylor, J. B.
Publisher: name: arXiv
Year: 2012
Subjects: subject: Plasma Physics (physics.plasm-ph)
subject: FOS: Physical sciences

description: There is a well established theory of Ballooning modes in a toroidal plasma. The cornerstone of this is a local eigenvalue lambda on each magnetic surface - which also depends on the ballooning phase angle k. In stationary plasmas lambda(k) is required only near its maximum, but in rotating plasmas its average over k is required. Unfortunately in many case lambda(k) does not exist for some range of k, because the spectrum there contains only a stable continuum. This limits the application of the theory, and raises the important question of whether this "stable interval" gives rise to significant damping. This question is re-examined using a new, simplified, model - which leads to the conclusion that there is no appreciable damping at small shear flow. In particular, therefore, a small shear flow should not affect Ballooning mode stability boundaries.

description: Global Navigation Satellite Systems are widely used as localization systems for various applications in indoor and outdoor environments. Autonomous vehicles for example rely on navigation sensors such as GNSS receivers, INS, odometers, LiDAR, radar, etc. However, none of these sensors alone is able to provide satisfactory position solutions in terms of accuracy, availability and reliability all the time and in all environments. This thesis presents a new tightly coupling method fusing the egomotion of a land vehicle estimated from a sky-pointing camera with GNSS signals and a digital map for navigation purposes in harsh urban canyon environments. The advantages of this configuration are three-fold: firstly, for the GNSS signals, the upward-facing camera will be used to classify the acquired images into sky and non-sky (known as segmentation). A satellite falling into the non-sky areas (e.g., buildings) will be rejected and not considered for the final position solution computation. Secondly, the narrow field of view sky-pointing camera is helpful for urban area egomotion estimation in the sense that it does not see most of the moving objects (e.g., cars) and thus is able to estimate the egomotion with fewer outliers than is typical with a forward-facing camera. Thirdly, the skyline can be extracted and serves as a finger print of the vehicle location in the city. This information can then be correlated with a 3D city model to obtain the vehicle location. In order to obtain an accurate solution from the proposed method, a few intermediate steps had to be taken into account. An improved image segmentation algorithm is presented. The output of this algorithm served for the skyline positioning and the camera-based multipath mitigation. Also, an accurate visual odometry was implemented. Moreover, the monocular-based visual odometry is able to determine the vehicle translation accurately but up to a scale only. An integrated system that tackles the scale factor issue is designed. From five datasets evaluated in this research, the proposed method has shown to be robust and provide more accurate position, velocity and attitude solution at least 83% of the time than the GNSS-only and loosely coupled GNSS/vision solutions.
A new global effort to control malaria

description: The global campaign to eradicate malaria, launched in 1955 and phased out by the end of the 1960s, has been dubbed a misguided failure. Although the campaign did not come close to achieving its headline objective of eradicating malaria, it did lead to enormous and sustained reductions in the burden of malaria in dozens of countries around the world. Unfortunately, the world failed to heed the right lesson: global eradication is not feasible, but sustained malaria control restricting transmission to low levels is. The time has come to resurrect a worldwide effort to control malaria, albeit one not predicated on complete eradication of the disease.

description: Objectives: To examine physical activity (PA), body composition, balance, and strength in youth (ages 10-18) with cerebral palsy (CP), compared to age- and sex-matched typically developing (TD) peers. Methods: Thirty youth with CP [gross motor function classification system (GMFCS) levels I-III; 20 males], were matched to TD youth. PA (minutes in sedentary, light, and moderate-vigorous) was measured using ActiGraph accelerometers. Body composition (fat and lean mass indices) was assessed by dual-energy x-ray absorptiometry. Center of pressure (total path length and 95% ellipse area) on two force plates represented balance. Lower-extremity strength was measured using hand-held dynamometry. Results: Youth with CP, GMFCS levels II or III, achieved less moderate-vigorous PA, were more sedentary, weaker with all lower-extremity muscle groups, had lower lean mass indices, and had larger 95% ellipse areas than TD youth. Conclusions: GMFCS level appeared to impact the severity of activity limitations and of body structure and functional impairments.

description: The vascular T-type Ca2+ channel, CaV3.2, regulates arterial tone by triggering Ca2+ sparks and activating large conductance Ca2+-activated K+ (BKCa) channels. Despite being an integral element of an arterial feedback loop, little is known of its regulation and how key receptors and signaling pathways use this channel to influence tissue perfusion. This thesis will begin to fill key knowledge gaps, undertaking experiments that progress from individual smooth muscle cells to whole arteries, and which entail the use of patch clamp electrophysiology, Ca2+ imaging, pressure myography, immunohistochemistry, quantitative polymerase chain reaction (qPCR) and computational modeling. In initial work, perforated patch electrophysiology was used in concert with Ca2+ imaging to illustrate the coordinated interplay between CaV3.2 and two other Ca2+ permeable conductances in setting voltage-dependent Ca2+ spark production and BKCa channel activation. A second layer of experiments subsequently revealed that caveolae help couple CaV3.2 to Ca2+ sparks generation by placing this T-type Ca2+ channel in close proximity to its intracellular target, ryanodine receptors (RyR). Disruption of the structural arrangement impaired the ability of CaV3.2 to mediate BKCa-mediated feedback in intact resistance arteries. Final experiments revealed that CaV3.2 channels are targeted by common vasoactive stimuli through unique signaling pathways. Of note, was the ability of Angiotensin II to suppress CaV3.2 channel activity through the generation of reactive oxygen species (ROS) by NADPH oxidase (Nox). In summary, this thesis advances our knowledge of Ca2+ handling in vascular smooth muscle by providing new regulatory insight into CaV3.2, a T-type Ca2+ channel involved in optimizing arterial tone and tissue perfusion.

description: We investigate percolation transitions in a nonlocal network model numerically. In this model, each node has an exclusive partner and a link is forbidden between two nodes whose $r$-neighbors share any exclusive pair. The $r$-neighbor of a node $x$ is defined as a set of at most $N^r$ neighbors of $x$, where $N$ is the total number of nodes. The parameter $r$ controls the strength of a nonlocal effect. The system is found to undergo a percolation transition belonging to the mean field universality class for $r< 1/2$. On the other hand, for $r>1/2$, the system undergoes a peculiar phase transition from a non-percolating phase to a quasi-critical phase where the largest cluster size $G$ scales as $G \sim N^α$ with $α= 0.74 (1)$. In the marginal case with $r=1/2$, the model displays a percolation transition that does not belong to the mean field universality class.

Can mandated political representation increase policy influence for disadvantaged minorities? Theory and evidence from India

Publisher: name: Columbia University
Year: 2002
Subjects: subject: Political science
subject: FOS: Political science

description: A basic premise of representative democracy is that every person subject to policy should have a voice in its making. However, policies enacted by electorally accountable governments often fail to reflect the interests of disadvantaged minorities. This paper uses political reservation in India to examine the role of mandated political representation in providing such groups policy influence. The Indian constitution mandates political reservation for disadvantaged castes and tribes in state elections - only members of these groups can stand for election in reserved jurisdictions. I find that political reservation in Indian states has increased targeted transfers to groups which benefit from the mandate. This finding underlines the importance of political representation in providing disadvantaged minorities' political voice. It also suggests that complete policy commitment may be absent in democracies, as is found in this case.

description: This paper examines how schools choose class size and how households sort in response to those choices. Focusing on the highly liberalized Chilean education market, we develop a model in which schools are heterogeneous in an underlying productivity parameter, class size is a component of school quality, households are heterogeneous in income and hence willingness to pay for school quality, and schools are subject to a class-size cap. The model offers an explanation for two distinct empirical patterns observed among private schools that accept government vouchers: (i) There is an inverted-U relationship between class size and household income in equilibrium, which will tend to bias cross-sectional estimates of the effect of class size on student performance. (ii) Some schools at the class size cap adjust prices (or enrollments) to avoid adding another classroom, which produces stacking at enrollments that are multiples of the class size cap. This generates discontinuities in the relationship between enrollment and household characteristics at those points, violating the assumptions underlying regression-discontinuity (RD) research designs. This result suggests that caution is warranted in applying the RD approach in settings in which parents have substantial school choice and schools are free to set prices and influence their enrollments.

We compute the Bredon homology for groups with aspherical presentation, one-relator quotients of products of locally indicable groups, extensions of $\mathbb{Z}^n$ by cyclic groups, and fuchsian groups. We take advantage of the torsion structure of these groups to use appropriate models of the universal space for proper actions which allow us, in turn, to extend some technology defined by Mislin in the case of one-relator groups.

description: Since the 1970's, the amount of environmental regulation at all levels of government has increased significantly. Major federal statutes include the Clean Air Act, Federal Water Pollution Act, Resource Conservation and Recovery Act (RCRA), Toxic Substances Control Act (ToSCA) and the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). In addition, states have their own environmental laws and regulations. The resulting web of often highly technical requirements makes it difficult for even the regulated enterprise itself to know whether it is in compliance with applicable law. In response, many firms have instituted a policy of conducting their own "environmental audits."

And I also want to thank the Kernochan Center and the Rockefeller Archives Center for the invitation to be here today. For reasons that will be apparent in my talk, I’ve been chomping at the bit to talk to lawyers about some of the problems we’re having in our current work. It’s been interesting to reflect on the sessions earlier in the focus on intellectual property and copyright. I think that sort of pertains to stuff we already have, and my focus is looking to the future, anticipating collections that we’re going to get. In this context, I think it’s important to distinguish between archives and special collections, because the context of what I’m talking about is our integral work with the archives of our own institution. As Bill was saying at the beginning, institutional archives have a sort of organic relationship to their records, and we’re entering into that kind of organic relationship. It’s a different kind of relationship that we have with our own materials versus what we might have with a historical collection that we go out and get and bring in. So we’re finding that it’s really more—in dealing with this—a cultural problem than a technical problem, for reasons that I’ll mention."

However, only partial results, focused for instance on the computation of the maximum storage capacity at zero temperature, have been obtained to date. In this work, we extended the study of the effect of these synaptic mechanisms on autoassociative neural networks to more realistic and general conditions, including the presence of noise in the system. In particular, we characterized the behavior of the system by means of its phase diagrams, and we concluded that synaptic facilitation significantly enlarges the region of good retrieval performance of the network. We also found that networks with facilitating synapses may have critical temperatures substantially higher than those of standard autoassociative networks, thus allowing neural networks to perform better under high-noise conditions.

description: Estimates of democracy's effect on the public sector are obtained from comparisons of 142 countries over the years 1960-90. Based on three tenets of voting theory - that voting mutes policy preference intensity, political power is equally distributed in democracies, and the form of voting processes is important - we expect democracy to affect policies that redistribute, or economically favor the political leadership, or enhance efficiency. We do not find such differences. Instead democracy is correlated with policies that limit competition for public office. Alternative modeling approaches emphasize the degree of competition, and deemphasize the form or even existence of voting processes.
Bushido : the creation of a martial ethic in late Meiji Japan
Creators: name: Benesch, Oleg
Publisher: name: University of British Columbia

description: This study examines the development of the concept of “bushido,” or the “way of the warrior,” in modern Japan, focusing on the period between the mid-nineteenth century and the early 1930s. The popular view holds that bushido was a centuries-old code of behavior rooted in the historical samurai class and transmitted into the modern period, where it was a fundamental component of Japanese militarism before 1945. In fact, the concept of bushido was largely unknown before the last decade of the nineteenth century, and was widely disseminated only after 1900, especially after the Russo-Japanese War of 1904-5. This study argues that modern bushido discourse began in the 1880s, and was dependent on political and cultural currents relating to Japan’s modernization and the nation’s attempts to redefine itself in the face of foreign “others,” primarily China and the West. Following more than a decade of largely unquestioned thrusts towards modernization and Westernization after 1868, Japanese thinkers looked to their own traditions in search of sources of national identity. The first discussions of bushido at this time were not the work of conservative reactionaries, however, but were conceived by relatively progressive individuals with considerable international experience and a command of Western languages. Some of the first modern writings on bushido clearly posit the concept as a potential native equivalent to the English ethic of “gentlemanship,” which was widely admired in late-nineteenth century Japan, and much of early bushido discourse should be seen primarily as a response to outside stimuli. This study examines the causes and effects of the “bushido boom” that took place between 1898 and 1914, which firmly established the concept not only in Japan, but throughout the world. In this context, this study analyzes the use of bushido by the Japanese military and educational system, as well as its popularization by prominent figures in the early twentieth century. This study also examines the reasons for the decline in the popularity of bushido between 1914 and the early 1930s, thereby providing points of departure for future research on the trajectory of bushido from 1932 to the present day.

description: Field experiment was conducted at Toke Kutaye District on farmer’s field at Birbirsa and Dogoma Kebele (lowest administrative unit) in 2015 main cropping season to determine the effect of compost integrated with nitrogen fertilizer. The experiment was laid out in randomized complete block design with three replications in factorial arrangement with four different rates of nitrogen fertilizer (0, 25% rec., 50% rec. and100% rec. or 0kg/ha, 23kg/ha, 46kg/ha and 92 kg/ha, respectively) and three levels of compost (0, 7.5 and 15t ha-1). Results showed that the main effect of compost significantly (P≤0.05) affected days to 50% tasseling, 50% silking, and 90% maturity, plant height, leaf area index, number of ears per plant, ear length, thousand kernels weight, and number of kernels per ear. Main effect of nitrogen significantly affected plant height, number of ears per plant, 1000-seed weight, dry biomass and grain yield. Moreover, the interaction effect of nitrogen and compost significantly (P≤0.05) influenced the number of kernels per ear, thousand seed weight, dry biomass and grain yield. Moreover, the highest dry biomass (16492.9 kg/ ha) and grain yield (8299kg/ ha) were recorded in the treatment that received 50% recommended N fertilizer combined with 15t/ha compost. Grain yield correlated positively with maize growth and yield components parameters. Based on the study findings, it is suggested that integrated use of N fertilizer at the rate of 50 % recommended combined with compost at 15t/ha had the potential to significantly increased maize yield in the study area

description: Solvent-based processes such as vapor extraction (VAPEX) can be another technology that has potential to enhance heavy oil recovery in a more cost-efficient and environment friendly way. Extensive experimental and simulation studies have been conducted to evaluate VAPEX. However, theoretical modeling has not gained much progress in the past two decades. This thesis aims at adopting a series of mathematical models for a new theoretical analysis of comprehensively evaluating solvent-based recovery processes and also attempts to develop a new process to enhance production. This thesis first develops a comprehensive theoretical analysis method for VAPEX, which considers all the major recovery mechanisms such as dynamic mass transfer, gravity drainage, multiphase flow, and boundary movement in the model. Both constant and variable diffusivity have been studied in this model, and the latter justified in the progressive change of properties such as viscosity in the media within the diffusion layer. A hot solvent injection process takes advantages of both thermal recovery processes (quick heat conduction and large viscosity reduction) and solvent-based processes (lower energy consumption and less green-house gas emission). This thesis then develops a transient mass transfer model to analyze the cold heavy oil–hot solvent mixing process during a hot solvent injection process. This mass transfer model is then incorporated into the VAPEX model to evaluate the performance of a hot solvent injection process. Key indicators such as oil production profile, injection pressure, injection temperature, solvent oil ratio, etc. have been studied to find out a quantitatively correlation. A new hybrid process, SAVE, is proposed to enhance heavy oil recovery. In this process, a short-slug steam and a long-slug solvent are alternately injected to extract heavy oil. Simulation results show that the cumulative steam-oil ratio of SAVE is 37.26% of that of SAGD. In comparison with VAPEX, SAVE produces oil 8.4 times faster than VAPEX and its cumulative solvent-oil ratio of SAVE is only 26% of that of VAPEX. SAVE performs relatively better in thinner formations than in thicker ones.
