Artists Under Reform: An Analysis of Professional Chinese Guohua Painters' Relation to the State in the Post-Mao Era
Keywords: guohua, Chinese national painting, Chinese professional guohua painters, party-state, political autonomy,

This thesis is purposefully limited to examining the status of China’s professional guohua (Chinese national painting) painters and their relation to the Party-State. It tackles the above subject by studying the contents of important official documents issued by the party-state, by retelling the interactions between professional guohua painters and the party-state in several crucial social-political contexts, and by analysing the experiences, opinions, observations and critiques of four professional guohua painters. The time span of this study extends from 1949 to the late 1990s, while acknowledging the year of 1978, when China officially launched its reform program, as a critical dividing juncture for comparative reasons. This thesis finds that a new favorable partnership was forged between the party-state and the professional guohua painters in the reform era. This was due to the impact of China’s political culture, changes in the ideology and policies of the ruling elite, the commercialization of art, and an emerging need to preserve guohua that is more instrumental to promote China’s cultural heritage and national soft power. It argues that the sustainability of such a partnership has been reinforced through a conscious differentiation between categories of art -- elite and non-elite, official and non-official, high and popular, public and non-public -- by Chinese cultural authorities as well as the artists themselves. This thesis further asserts that the significantly improved economic conditions and the social status that professional guohua painters enjoyed in the 1980s and 1990s did not reflect on their cultural and political autonomy. Most of them consciously chose to be part of the institutional establishments under the party-state and showed limited aspiration in the quest for cultural and political autonomy. The “organized dependence” of professional guohua painters prior to the reform era was replaced by “conformity” of these artists towards the party-state. Finally it suggests that, although China’s changing political environment will eventually give way to economics and the scale of ideological movements and cultural control will continue to decline, many professional guohua painters are likely to stay within the ideological and aesthetic boundaries set by the party-state and to be part of official arts agencies and institutions.
Investigating Executive Functioning in Everyday Life using an Ecologically Oriented Virtual Reality Task
Keywords: neuropsychology

Commonly employed executive function measures may be of limited use due to their modest ecological validity. A novel task was developed - the Multitasking in the City Test (MCT) - in an attempt to improve ecological validity. The MCT involves task demands that resemble the demands of everyday activities. In study one, healthy participants were recruited in order to explore ‘normal’ performance on the MCT and its relationship with other cognitive measures. The MCT showed poor associations with executive tests and significant correlations with non-executive tests. This suggested the MCT may evaluate executive functioning in a different way from other executive measures such that it does not simply measure component executive processes but the integration of these components into meaningful behaviour. Patients with stroke and traumatic brain injury were recruited for study two to further explore the ecological validity and MCT performance characteristics. Only the MCT and a semantic fluency task demonstrated good ecological validity via significant relationships with a behavioural rating scale. Patients and normals made qualitatively similar types of errors although patients made these errors more frequently. Patients demonstrated better planning ability but completed fewer tasks than normals on the MCT. This discrepancy was attributed to impaired initiation. In study three, the MCT and verbal fluency tasks were administered to brain-injured individuals both pre- and post-executive function rehabilitation to evaluate their utility as treatment outcome measures and to assess ecological validity via a different behavioural rating scale from the one used in study two. Strategies trained during treatment generalized to MCT but not verbal fluency performance. Both MCT and semantic fluency performance were found to have good ecological validity. Overall, the findings from this research project suggest the MCT and semantic fluency tasks have good ecological validity. They further suggest that several common executive function measures lack adequate ecological validity and may not be predictive of real world behaviour. Moreover, these results support the concept of an executive function ‘system’ that can be fractionated into a variety of executive processes and that impairments in one process (e.g., initiation) can exist alongside intact functioning in other processes (e.g., planning).
Probing Early and Late Inflations Beyond Tilted LambdaCDM
Keywords: cosmology

non-Gaussianity

The topic of this thesis is about cosmic inflations, including the early-universe inflation that seeds the initial inhomogeneities of our universe, and the late-time cosmic acceleration triggered by dark energy. The two inflationary epochs have now become part of the standard ΛCDM cosmological model. In the standard paradigm, dark energy is a cosmological constant or vacuum energy, while the early-universe inflation is driven by a slowly rolling scalar field. Currently the minimal ΛCDM model with six parameters agrees well with cosmological observations. If the greatest achievement of the last twenty golden years of cosmology is the ΛCDM model, the theme of future precision cosmology will be to search for deviations from the minimal ΛCDM paradigm. It is in fact expected that the upcoming breakthroughs of cosmology will be achieved by observing the subdominant anomalies, such as nonGaussianities in the Cosmic Microwave Background map. The aim of this thesis is then to make theoretical predictions from models beyond ΛCDM, and confront them with cosmological observations. These models include: 1) a new dark energy parametrization based on quintessence models; 2) reconstructing early-universe inflationary trajectories, going beyond the slow-roll assumption; 3) non-Gaussian curvature fluctuations from preheating after the early-universe inflation; 4) infra-red cascading produced by particle production during inflation; 5) preheating after Modular inflation; 6) decaying cold dark matter. We update the cosmological data sets – Cosmic Microwave Background, Type Ia supernova, weak gravitational lensing, galaxy power spectra, and Lyman-α forest – to the most current catalog, and run Monte Carlo Markov Chain calculations to obtain the likelihood of parameters. We also simulate mock data to forecast future observational constraints.
Learning Language-vision Correspondences
Keywords: image annotation
object recognition

Given an unstructured collection of captioned images of cluttered scenes featuring a variety of objects, our goal is to simultaneously learn the names and appearances of the objects. Only a small fraction of local features within any given image are associated with a particular caption word, and captions may contain irrelevant words not associated with any image object. We propose a novel algorithm that uses the repetition of feature neighborhoods across training images and a measure of correspondence with caption words to learn meaningful feature configurations (representing named objects). We also introduce a graph-based appearance model that captures some of the structure of an object by encoding the spatial relationships among the local visual features. In an iterative procedure we use language (the words) to drive a perceptual grouping process that assembles an appearance model for a named object. We also exploit co-occurrences among appearance models to learn hierarchical appearance models. Results of applying our method to three data sets in a variety of conditions demonstrate that from complex, cluttered, real-world scenes with noisy captions, we can learn both the names and appearances of objects, resulting in a set of models invariant to translation, scale, orientation, occlusion, and minor changes in viewpoint or articulation. These named models, in turn, are used to automatically annotate new, uncaptioned images, thereby facilitating keyword-based image retrieval.
Potentiometric pH Measurements in the Pressure Acid Leaching of Nickel Laterites
Keywords: pH measurement
Pressure Acid Leaching

An electrochemical cell consisting of a flow-through yttria-stabilized zirconia (YSZ) sensor and a flow-through Ag/AgCl reference electrode has been employed to measure pH of high-temperature acidic sulphate solutions relevant to the pressure acid leaching (PAL) of nickel laterites. In a previous study, this cell was used to measure pH of H2SO4, Al2(SO4)3-H2SO4 and MgSO4-Al2(SO4)3-H2SO4 solutions at 250oC. In this work, the solutions range in complexity from the binary MgSO4-H2SO4, NiSO4-H2SO4, and Al2(SO4)3-H2SO4, through the ternary MgSO4-Al2(SO4)3-H2SO4 and NiSO4-Al2(SO4)3-H2SO4, to the PAL process solutions, whereas the temperature ranges from 200oC to 250oC. The measured and theoretical pH values typically agree within less than 0.1 pH unit and 0.2 pH units in synthetic solutions and PAL solutions, respectively. This is an improvement over the results of the previous study in synthetic solutions, which show differences between theory and experiment as high as 0.4 pH units. The conversion of measured potentials into pH values is based on the new mixed-solvent electrolyte (MSE) speciation model of the OLI Systems software calibrated independently based on solubility measurements. Both Henderson’s equation and the exact definition of the diffusion potential were employed in treating the obtained experimental data. Experimental pH values calculated using the diffusion potentials evaluated by either approach are essentially the same. This finding suggests that Henderson’s equation, which is based on readily available limiting ionic mobilities, can be effectively used. Lithium chloride is found to be a suitable alternative to sodium chloride as the reference electrode solution for the measurement of pH of aluminium-containing solutions, because it did not induce precipitation of aluminium as an alunite-type compound. The experimental results indicate that the high-temperature behaviour of Ni, Co and Mn sulphates can be satisfactorily approximated with that of MgSO4. The experimental findings also support the postulation that acid should be added to a PAL process so that the solution pH is around 1 at the leach temperature, regardless of the feed composition. The cell can be used for hydrometallurgical process research and development on a laboratory scale with very satisfactory performance, provided that a well-behaved YSZ sensor is available.
A Modeling Study of Seasonal and Inter-annual Variations of the Arctic Black Carbon and Sulphate Aerosols
Keywords: Arctic

The modeling results of current global aerosol models agree, generally within a factor of two, with the measured surface concentrations of black carbon (BC) and sulphate (SF) aerosols in rural areas across the northern continents. However, few models are able to capture the observed seasonal cycle of the Arctic aerosols. In general, the observed seasonality of the Arctic aerosols is determined by complex processes, including transport, emissions and removal processes. In this work, the representations of aerosol deposition processes (i.e., dry deposition, in-cloud and below-cloud scavenging) within the framework of the Canadian Global Air Quality Model – GEM-AQ are first enhanced. Through the enhancements in GEM-AQ, the seasonality of the Arctic BC and SF is reproduced, and the improvement in model performance extends to the rest of the globe as well. Then, the importance of these deposition processes in governing the Arctic BC and SF seasonality is investigated. It is found that the observed seasonality of the Arctic BC and SF is mainly caused by the seasonal changes in aerosol wet scavenging, as well as the seasonal injection of aerosols from surrounding source regions. Being able to reproduce the seasonality of the Arctic BC, the enhanced GEM-AQ allows more accurate assessment of the contributions of anthropogenic sources to the BC abundance in the Arctic air and deposition to the Arctic surface. Simulating results on regional contributions to the Arctic BC show a strong dependence on altitude. The results reinforce the previous finding of Eurasia being the dominant contributor to the surface BC in the Arctic, and suggest a significant contribution from Asian Russia. In addition to the seasonality of the Arctic aerosols, the inter-annual variation in the Arctic BC surface concentration is also investigated. To complement the 3-D GEM-AQ model, the atmospheric backward trajectory analysis, together with estimated BC emissions, is implemented as a computational effective approach to reconstruct BC surface concentrations observed at the Canadian high Arctic station, Alert. Strong correlations are found between the reconstructed and the measured BC in the cold season at Alert between 1990 and 2005, which implies that atmospheric transport and emissions are the major contributors to the observed inter-annual variations and trends in BC. The regional contributions estimated annually from 1990 through 2005 suggest that Eurasia is the major contributor in winter and spring to the near-surface BC level at Alert with a 16-year average contribution of over 85% (specifically 94% in winter and 70% in spring). A decreasing trend in the Eurasian contribution to the Arctic is found in this study, which is mainly due to regional emission reduction. However, the inter-annual variation in the North American contribution shows no clear trend.
International Taxation and Income-shifting Behaviour of Multinational Corporations
Keywords: income shifting
international taxation

This thesis examines the income-shifting behaviour of multinational corporations when they are facing international corporate income tax rate differentials. Multinational corporations may apply tax-planning strategies in order to shift their pre-tax profits from a high-tax country to a low-tax country; therefore, the same amount of money would be subject to a lower tax rate. By doing so, multinational corporations minimize their global tax liabilities without changing their total income. The first essay develops a simple general equilibrium model by which to explore the effect of tax planning on the host country in terms of social welfare and optimal taxation. We endogenize multinational corporations’ investment decisions by allowing the user cost of capital to be affected by shifting decisions. We find that if tax rates are not excessively high, then an increase in tax planning activity causes a rise in optimal corporate tax rates, and a decline in multinational investment. Thus, fears of a “race to the bottom” in corporate tax rates may be misplaced. Also, we find that the residents in high-tax countries may be better off with (some) income shifting. We prove that there is an interior optimal thin capitalization rule (a restriction on the debt-to-equity ratio) that is lower than the degree of tax planning preferred by multinational firms. The second essay empirically examines the evidence of income-shifting behaviour of Canadian multinational corporations. The results are consistent with the income-shifting hypothesis that multinationals are inclined to shift their pre-tax profits to low-tax jurisdictions. I find that having non-arm’s length transactions with related parties in tax-haven countries has a significant negative impact on the taxable income that is reported in Canada. Further, I compare the different roles between small havens and large havens and find that the effect of having transactions with small havens is significantly negative, while the effect of having transactions with large tax havens is not significant. Also, I find that if Canadian corporations control their foreign-related corporations with whom they had non-arm’s length transactions, then they are more likely to report lower taxable incomes in Canada than are those that have other types of relationships with their foreign-related corporations.
A Critical Modern-spelling Edition of John Fletcher's "Rule a Wife and Have a Wife"
Keywords: John Fletcher
Renaissance Drama

This dissertation is a fully-annotated scholarly edition of John Fletcher's 1624 play <i>Rule a Wife and Have a Wife</i>. Fletcher's comedy of intrigue about two couples who wed under false pretenses was his final non-collaborative play and represents the culmination of his achievements as a comic dramatist. It has received surprisingly little attention for a play that remained a staple of English and American theatres into the 1860s. The introduction to this edition is the most comprehensive study of the play to date. The critical examination of the domestic politics and structural patterning of the play argues that <i>Rule a Wife and Have a Wife</i> presents marriages that become protective spheres to shield spouses from the twin depredations of economic necessity and tyrannical power once the spouses have given up the urge to dominate each other. A section on Fletcher's language and style explores what Dryden praised as its imitation of the "conversation of gentlemen." The study of Fletcher's source material considers not only the two Spanish narratives he adapted, but also the resources of the King's Men and their theatres which influenced the play's composition. The introduction then contextualizes the play in its initial historical moment and the ways it reacts to England's preparations for war and the marriage negotiations for Prince Charles. The final two sections of the introduction examine the play's circulation in print and on stage. The stage history is supplemented by two appendices: a calendar of nearly 800 known performances and a collation of changes made in acting editions of the play. A recognition of the style and ubiquity of <i>Rule a Wife and Have a Wife</i> will aid scholars in understanding continuities of taste and repertoire in English drama.
Circuit Timing and Leakage Analysis in the Presence of Variability
Keywords: process variations, parameterized static timing analysis, variation-aware performance analysis

Driven by the need for faster devices and higher transistor densities, technology trends have pushed transistor dimensions into the deep sub-micron regime. This continued scaling, however, has led to many challenges facing digital integrated circuits today. One important challenge is the increased variations in the underlying process and environmental parameters, and the significant impact of this variability on circuit timing and leakage power, making it increasingly difficult to design circuits that achieve a required specification. Given these challenges, there is a need for computer-aided design (CAD) techniques that can predict and analyze circuit performance (timing and leakage) accurately and efficiently in the presence of variability. This thesis presents new techniques for variation-aware timing and leakage analysis that address different aspects of the problem. First, on the timing front, a pre-placement statistical static timing analysis technique is presented. This technique can be applied at an early stage of design, when within-die correlations are still unknown. Next, a general parameterized static timing analysis framework is proposed, which supports a general class of nonlinear delay models and handles both random (process) parameters with arbitrary distributions and non-random (environmental) parameters. Following this, a parameterized static timing analysis technique is presented, which can capture circuit delay exactly at any point in the parameter space. This is enabled by identifying all potentially critical paths in the circuit through novel and efficient pruning algorithms that improve on the state of art both in theoretical complexity and runtime. Also on the timing front, a novel distance-based metric for robustness is proposed. This metric can be used to quantify the susceptibility of parameterized timing quantities to failure, thus enabling designers to fix the nodes with smallest robustness values in order to improve the overall design robustness. Finally, on the leakage front, a statistical technique for early-mode and late-mode leakage estimation is presented. The novelty lies in the random gate concept, which allows for efficient and accurate full-chip leakage estimation. In its simplest form, the leakage estimation reduces to finding the area under a scaled version of the within-die channel length auto-correlation function, which can be done in constant time.
Tracing the Itinerant Path: Jishū Nuns of Medieval Japan
Keywords: Medieval Japan

Medieval Japan was a fluid society in which many wanderers, including religious preachers, traveled the roads. One popular band of itinerant proselytizers was the jishū from the Yugyō school, a gender inclusive Amida Pure Land Buddhist group. This dissertation details the particular circumstances of the jishū nuns through the evolving history of the Yugyō school. The aim is to provide a comprehensive understanding of the gender relations and the changing roles women played in this itinerant religious order. Based on the dominant Buddhist view of the status of women in terms of enlightenment, one would have expected the Buddhist schools to have provided only minimal opportunities for women. While the large institutionalized monasteries of the time do reflect this perspective, schools founded by hijiri practitioners, such as the early Yugyō school, contradict these expectations. This study has revealed that during the formation of the Yugyō school in the fourteenth century, jishū nuns held multiple and strong roles, including leadership of mix-gendered practice halls. Over time, as the Yugyō school became increasingly institutionalized, both in their itinerant practices and in their practice halls, there was a corresponding marginalization of the nuns. This thesis attempts to identify the causes of this change and argues that the conversion to a fixed lifestyle and the adoption of mainstream Buddhist doctrine discouraged the co-participation of women in their order.
