Floating as the Keyword: Chinese Independent Documentary Films in Post-Socialist China
Keywords: cinema
Mass Communications
Cultural

Independent documentary films have made floating population– such as the migrants and people who flow from place to place– a prominent screen scene against China’s social and cultural landscapes since the 1990s. This study investigates how a “floating generation” of Chinese filmmakers has been formed and represented as an imagined community in China’s post-socialist context through Chinese independent documentaries. An attempt to excavate and examine the problems behind the instable but also flexible status of Chinese independent filmmaking within the state censorship, my study focuses on the implications of the keyword “floating” as they unfold along the development of Chinese independent documentary films. In a case study of Jia Zhangke’s three documentaries, In Public, Dong and Useless, my study analyzes the relationship between independent documentaries and China’s campaign of “constructing a harmonious society”.

Magnetorquer Coil

The Generic Nanosatellite Bus (GNB) is a spacecraft platform designed to accommodate the integration of diverse payloads in a common housing of supporting components. The development of the GNB at the Space Flight Laboratory (SFL) under the Canadian Advanced Nanospace eXperiment (CanX) program provides accelerated access to space while reducing non-recurring engineering (NRE) costs. The work presented herein details the development of the attitude determination and control subsystem (ADCS) of the GNB. Specific work on magnetorquer coil assembly, integration, and testing (AIT) and reaction wheel testing is included. The embedded software development and unit-level testing of the GNB sun sensors are discussed. The characterization of the AeroAstro star tracker is also a major focus, with procedures and results presented here. Hardware models were developed and incorporated into SFL's in-house high-fidelity attitude dynamics and control simulation environment. This work focuses on specific contributions to the CanX-3, CanX-4&5, and AISSat-1 nanosatellite missions.
Embedded Software Design for the Canadian Advanced Nanospace eXperiment Generic Nanosatellite Bus
Keywords: Embedded Software
GNB

The Space Flight Lab (SFL) at the University of Toronto Institute for Aerospace Studies (UTIAS) has developed an ambitious satellite program called the Canadian Advanced Nanospace eXperiment (CanX). The newest generation of CanX missions are based on the Generic Nanosatellite Bus (GNB). This bus was designed to accommodate many missions using a single, common platform. Currently, there are three nanosatellite missions using the GNB design. These missions include AISSat-1, CanX-3 (BRITE) and CanX-4&5. This thesis describes the high level embedded software design for the on-board computer (OBC), as part of the generic nanosatellite bus. The software discussed includes the Universal Asynchronous Receiver/Transmitter (UART) Thread, Serial Communications Controller (SCC) Thread, Inter-Integrated Circuit (I2C) Thread, Serial Peripheral Interface (SPI) Thread, Communications Thread, Memory Management Thread, Power Thread, House Keeping Computer (HKC) Thread, AISSat-1 Payload Thread and the Time Tag Thread. In addition to the application threads mentioned above, the software design and validation of the On Board Computer (OBC) design for the AISSat-1 mission is also discussed.
Power System Design, Analysis, and Power Electronics Implementation on Generic Nanosatellite Bus (GNB) Spacecraft
Keywords: Spacecraft
Power Systems

The development of a multi-mission small spacecraft power system is described. This system has been designed for the University of Toronto Space Flight Laboratory Generic Nanosatellite Bus (GNB), an approximately 20cm cubical spacecraft with no deployed solar arrays. The GNB is inherently power-generation limited, and consequently, all available power must be utilized with maximum efficiency. This efficiency is achieved using an unconventional parallel-regulated architecture with Peak Power Tracking (PPT) functionality, and is shown to be the PPT design of highest efficiency for spacecraft of this class. In support of this design, a novel spacecraft power simulation suite has been developed, enabling parametric satellite power analysis with high fidelity. Finally, a unique variation on peak power tracking---referred to as peak current tracking---is described. This method is shown to reduce battery depth-of-discharge by as much as 20% over baseline architectures, and furthermore exhibits beneficial emergent behaviour for battery charge management.
Changing the Climate: Labour-environmental Alliance-forming in a Neoliberal Era

Canada

This research explores how unions, corporations and the federal government in Canada are responding to the dual economic and climate change crisis. Climate change politics have fostered alliance-forming both between the labour and environmental movements as well as between the state and capital. Climate change policy over the past two decades has been a planned, coordinated neoliberal project by the state and capital that has led to increasing emissions. Meanwhile, most unions successfully transcended the ‘jobs versus the environment’ dichotomy being used by business to propagate a voluntarist climate change policy. After giving their support to the ratification of Kyoto, labour has struggled to operationalize labour-environmental alliance-forming. Recently, both labour and the state-capital alliance have drawn on an ecological modernist discourse to frame climate change as an opportunity for jobs or capital accumulation, respectively. But this discourse fails to address the transnational dynamics of climate change, and economic and environment justice.
Experimental Validation of Mathematical Models to Include Biomechanics into Dose Accumulation Calculation in Radiotherapy
Keywords: radiotherapy
dose
deformable image registration

3D dosimeter

Inaccurate dose calculation in radiotherapy can lead to errors in treatment delivery and evaluation of treatment efficacy. Respiration can cause of intra-fractional motions, leading to uncertainties in tumor targeting. These motions should therefore be included in dose calculation. The finite element method-based deformable registration platform MORFEUS is able to accurately quantify organ deformations. The dose accumulation algorithm included in MORFEUS takes organ deformation and tumor movement into account. This study has experimentally validated this dose accumulation algorithm by combining 3D gel dosimetry, respiratory motion-mimicking actuation mechanism, and finite element analysis. Results have shown that within the intrinsic measurement uncertainties of gel dosimetry, under normal conformal dose distribution conditions, more than 90% of the voxels in MORFEUS generated dose grids have met the criterion analogous to the gamma test. The average (SD) distance between selected pairs of isodose surfaces on the gel and MORFEUS dose distributions is 0.12 (0.08) cm.
Diversity on Adjudicative Administrative Tribunals: An Integrative Conception
Keywords: diversity
administrative tribunals

This thesis applies arguments for greater diversity, and more specifically, racial diversity, on the judiciary to administrative tribunals with an adjudicative function. I draw from both formal arguments, such as institutional legitimacy, and substantive arguments, such as the different perspectives that diversity would provide, to propose an integrative conception of diversity. By relying upon concepts such as structural impartiality, I argue that an integrative conception of diversity more fully reveals the transformative potential of diversity in legal decision-making. This integrative conception is particularly well-suited to the administrative context because it demonstrates how diversity will enhance the values of participation and justification, which are instrumental to the principle of fairness. Through interviews with adjudicators and legal clinic lawyers, I offer a preliminary view of the potential impact that diverse administrative adjudicators could have in practice. Finally, this thesis offers recommendations on how this potential could be further realized.
Deformable Registration using Navigator Channels and a Population Motion Model
Keywords: Deformable Registration
Image-Guided Radiotherapy

Radiotherapy is a potential curative option for liver cancer; however, respiratory motion creates uncertainty in treatment delivery. Advances in imaging and registration techniques can provide information regarding changes in respiratory motion. Currently image registration is challenged by computation and manual intervention. A Navigator Channel (NC) technique was developed to overcome these limitations. A population motion model was generated to predict patient-specific motion, while a point motion detection technique was developed to calculate the patient-specific liver edge motion from images. An adaptation technique uses the relative difference between the population and patient calculated liver edge motion to determine the patient's liver volume motion. The NC technique was tested on patient 4D-CT images for initial validation to determine the accuracy. Accuracy was less than 0.10 mm in liver edge detection and approximately 0.25 cm in predicting patient-specific motion. This technique can be used to ensure accurate treatment delivery for liver radiotherapy.
A Digitally Controlled Dual Output Stage Buck Converter with Transient Suppression
Keywords: DC-DC Converters
Transient Response
Digital Control

To support the increasingly demanding requirements for power conversion units, a digitally controlled dual output stage buck converter is designed. The system consists of a dual output stage, which includes an auxiliary buck output stage connected in parallel with a main output stage. The auxiliary output stage is only active during load transient to suppress the output voltage variation. A digital controller is designed to control both stages with a linear/nonlinear control scheme. Nonlinear control is applied during load transient based on the capacitor charge balance principle; whereas linear PID control governs the steady state operation. The design is verified with simulation and experimentally with discrete components. The controller is realized with a FPGA with preset output stage parameters. The experimental result shows a 60% reduction of output voltage variation for a heavy-to-light load transient.
IInterface Design for an Automated Combat Identifcation System: Displaying Reliability Information
Keywords: Human Factors
Interface Design
Combat Identification
Attention
Military

Users have difficulty relying on automated combat identification aids; however, verbally informing users of the automation reliability has helped them rely on the automation more appropriately. A number of interfaces that displayed automation reliability information in real time were developed and tested. In Experiment I, participants used the interfaces in the IMMERSIVE simulation, a first person shooter game. The results showed that the form of the interface affected both reliance on the automation and sensitivity in discriminating hostile and friendly targets. The difference in sensitivity and reliance may be attributed to how participants allocated their attention among the displays. In Experiment II, still combat scenes were presented to the participants for 400 or 800 milliseconds (as opposed to 10 seconds in Experiment I) to place additional time stress on attention resources. The results replicated the results of Experiment I, but sensitivity measures showed a dependence on reliability of the automation.
Predictors of Peritonitis Among Canadian Peritoneal Dialysis Patients
Keywords: peritoneal dialysis

predictors

Despite the decreasing incidence of peritoneal dialysis (PD) peritonitis over time, its occurrence is still associated with adverse outcomes. This thesis focuses on determining factors associated with PD peritonitis in order to facilitate identification of patients at risk. Using data collected in a multicentre Canadian database between 1996 and 2005, the study population comprised 4,247 incident PD patients, of whom 1,605 had at least one peritonitis episode. Variables independently associated with peritonitis included age [rate ratio (RR) 1.04 per decade increase, 95% CI 1.01-1.08], Black race (RR 1.37, 95% CI 1.00-1.88) and having transferred from hemodialysis (RR 1.24, 95% CI 1.11-1.38). There was an interaction between gender and diabetes (p=0.011), with an increased peritonitis risk only among female diabetics (RR 1.27, 95% CI 1.10-1.47). Choice of continuous ambulatory PD vs. automated PD did not influence peritonitis risk. These results contribute to our understanding of peritonitis risk among PD patients.
The Ontario Structures of Care in Colorectal Cancer Surger Study (OSCRC): Assessing Hospital Level Variation and Impact on Short Term Patient Outcomes
Keywords: Outcomes
Health Services Research

Introduction: Surgical treatment is the cornerstone of the management of colorectal cancer (CRC). This study described the structures of care at Ontario hospitals performing CRC surgery. Methods: Patients diagnosed with CRC undergoing surgery were identified from 2003-2007. Data linkage identified all institutions performing CRC surgery. Multiple hospital level structures were measured. For the final year of our study, the impact of these structures on 30-day mortality was evaluated. Results: 20,784 patients underwent CRC surgery. Each year, between 106 and 109 institutions performed at least one CRC operation. There was variation in hospital level structures of care. After adjustment for patient characteristics, no hospital level structures were independently associated with 30d mortality. Conclusions: Although variation in surgical care and patient outcomes is likely related to variation in processes and structures of care, after adjusting for covariates, our study did not show any significant relationship between hospital level structures and 30-day mortality.
Enantioselective Synthesis of Substituted Polycyclic Heterocycles by Rhodium-catalyzed Ring Opening Reactions of Aryne Diels-Alder Adducts

Polycyclic Heterocycles

We report the application of our rhodium-catalyzed nucleophilic ring-opening methodology to the enantioselective synthesis of nitrogen-substituted polycyclic heterocycles. By using a cationic Rh(I) triflate catalyst in the presence of the chiral Josiphos ligand PPF-PtBu2, the ring opening reactions on dihydrooxaquinoline and dihydrooxaisoquinoline using different nucleophiles afford access to multiple dihydroquinolines and dihydroisoquinolones in high yield and high enantioselectivity (up to 99% total yield and >99%ee). A variety of nucleophiles were shown to be compatible with the catalytic system. The electronic effects in the new ring opening reactions were investigated using a variety of nucleophiles. It was found that reactivity and enantioselectivity of the ring opening products depends on the electronic effects as well as the position of the substituents on the substrates. Good yields and high ee of regioisomeric products are obtained using electron donating substituents, whereas electron withdrawing substituents decelerate the reactions.
Optical Properties of Magic-sized Nanocrystals: Absence of Inhomogeneous Line Broadening and Direct Evidence of Energy Transfer Between Two Magic Sizes
Keywords: Magic-sized nanocrystals
Photoluminescence
Inhomogeneous line broadening
Energy transfer
CdSe nanocrystals

Magic-sized nanocrystals (MSNs) are nanocrystals with a single size distribution. They have narrow spectral features that do not exhibit inhomogeneous line broadening. This enabled us to analyze homogeneous line broadening of CdSe and CdTe MSNs. In solution, we observed two aggregated configurations of CdSe and CdTe MSNs. Sub-peaks within MSN excitonic peaks were caused by these two aggregated configurations and surface states. A two-dimensional photoluminescence spectrum of a mixture of CdTe 427 nm and 500 nm MSNs gave direct evidence of Förster resonant energy transfer (RET) between the two sizes of MSNs. Normalized experimental overlap between donor emission and acceptor absorption spectra was on the order predicted by theory, confirming that there is sufficient overlap for RET to take place in this system. Additionally, within both aggregated configurations, the two sizes of MSNs were within sufficient distance from one another for RET to occur.
The Impact of CYP2A6 Genotype on Smoking Cessation in an Extended Nicotine Patch Therapy Clinical Trial
Keywords: CYP2A6

We investigated the efficacy of standard (8-week nicotine, 16-week placebo) vs extended (24-week nicotine) patch therapy for smoking cessation, and the effect of slow nicotine metabolism, indicated by CYP2A6 reduced metabolizer (RM) genotype or low 3-hydroxycotinine/cotinine ratio (3HC/COT), on abstinence. RM versus normal genotype predicted lower 3HC/COT. Extended vs standard treatment produced higher abstinence at 24 weeks (32% vs 20%), but not at 52 weeks (both 14%). Low 3HC/COT and RM genotype predicted higher abstinence on extended versus standard treatment at 24 (47% vs 25%, 38% vs 17%) and 28 weeks (34% vs 19%, 23% vs 11%), while high 3HC/COT or normal genotype did not. Within extended treatment, low versus high 3HC/COT predicted higher abstinence at 8 (48% vs 29%), 24 (47% vs 25%), and 28 weeks (34% vs 16%), with similar trends for the genotype effect. Overall, extending nicotine treatment increased abstinence during therapy, particularly for slow metabolizers.
Salicylic Acid Accumulation Causes Alteration in Abscisic Acid Signaling and Induces Abscisic Acid Insensitivity in the Lesion Mimic Mutant cpr22
Keywords: Arabidopsis

Plant stress responses

Some Arabidopsis lesion mimic mutants (LMM) show alterations in abiotic stress responses as well as pathogen resistance. cpr22 is a LMM which has a mutation in cyclic nucleotide-gated ion channels, is a typical LMM exhibiting elevated levels of salicylic acid (SA), spontaneous cell death, constitutive expression of defense genes, and enhanced resistance to various pathogens in an SA dependant manner. cpr22 defense responses are suppressed in high humidity and enhanced by low humidity. To investigate environmental effects, microarray analyses were conducted. Expression of several genes related to abscisic acid (ABA) signaling was altered and ABA levels increased in cpr22 after humidity shift. Furthermore, significant alterations in ABA-related phenotypes were observed. Double mutant analysis with nahG plants indicated that alterations in ABA signaling were attributable to elevated SA levels. These results suggest a negative effect of SA on ABA signaling/abiotic stress responses during the activation of defense responses.
The Molecular and Genetic Interactions Between Pax3 and Alx4
Keywords: Pax3
Alx4
Protein-Protein Interactions

Alx4 is a paired-type homeodomain transcription factor that plays a key role in development, strongly expressed in the first branchial arch and craniofacial region. Pax3 also belongs to this family, and it displays a similar pattern of expression to that of Alx4. When Pax3 or Alx4 activity is lost individually, defects arise in an overlapping set of embryonic structures. In addition to their expression patterns, this suggests that these two factors may interact to play a role in normal murine development. We demonstrate an overlapping pattern of expression of Pax3 and Alx4 in the developing embryo and that Pax3 and Alx4 physically interact in vivo and in vitro. Pax3 and Alx4 can activate transcription from a P3 homeodomain consensus site, and preliminary analysis of mice null for both Pax3 and Alx4 show a novel mutant phenotype. We have therefore demonstrated a physical and genetic interaction between Pax3 and Alx4.
Bil'in and Beyond - Prosecuting Corporate Complicity in War Crimes under Canadian Law
Keywords: corporate complicity

Bil'in

This paper outlines a prosecutorial framework by which Canadian corporations can be held criminally liable for their involvement in war crimes, crimes against humanity or genocide. Combining the provisions of the Crimes Against Humanity and War Crimes Act with the corporate liability standards found in the Canadian Criminal Code, a standard of liability emerges which appears well designed to generate findings of guilt against multinational corporations with complicated ownership structures, a myriad of representatives and far-flung operations. This model standard, it is hoped, might furthermore contribute to the global debate regarding multinational corporate accountability. By applying the proposed framework to two Canadian corporations constructing internationally illegal settlements on the farmlands of Bil‘in in the West Bank, I therefore seek to test its practical relevance, as well as to demonstrate the theoretical underpinnings and legal sources (domestic and international) which would support its application, both in this instance and beyond.

Universities have traditionally stood as bastions of academic freedom and forums for open discourse and free expression. In recent years, however, this role has been questioned in instances where university administrators have, either directly or complicity, denied students the opportunity to express certain viewpoints they deem “controversial”. This research paper explores whether a university, or its delegates, should be allowed to deny students access to campus facilities and resources solely on the basis of ideological viewpoint. The relevance of the Canadian Charter of Rights and Freedoms, statutory human rights provisions, and common law doctrines to the student-university relationship are explored in turn. It is argued that, notwithstanding the fact that universities may be “private” actors to whom the Charter does not directly apply, they are institutions invested with a public interest, and as such ought to be subject to special duties of non-discrimination.
