description: Freshwater teleost fish often experience natural and anthropogenic conditions that result in fluctuating energy availability, therefore the ability to acquire, transform and use energy is essential for the survival of these fish. Polychlorinated biphenyls (PCB's) are recognized as physiological sources of stress to fish as they incite defense mechanisms that are generally costly in terms of metabolic resources. Over time, such responses may decrease individual performance and possibly fitness by changes in foraging, migration and escape behaviors, and the population in terms of reproductive capacity due to the alterations in energy allocation following an exposure. The main goal of this study was to determine if a sublethal exposure to PCB-126 affects the energy budget of the fish and can therefore be responsible for functional deficiencies associated with their locomotion. Fish were injected low (100 mug/kg) and high (400 mug/kg) concentrations of PCB-126 and swimming performance parameters including critical swimming speed, metabolic rate and recovery ratios were evaluated. EROD activity was also measured in the liver as an indication of PCB-126 intoxication while blood and white muscle tissue metabolites were analyzed to quantify the physiological disturbance levels associated with this exposure. A significant decrease was observed in the swimming performance of rainbow trout for the low and high PCB-126 treatments as well as an impaired recovery with increasing level of PCB exposure following exhaustive exercise. This study also showed the occurrence of physiological disturbance by a reduction in the hepatosomatic and spleen somatic indices and elevation of plasma cortisol and glucose levels, as well as white muscle reductions in glucose and glycogen indicating higher metabolic costs during recovery and muscle restoration for PCB-exposed fish. Overall, this research provides insights into the sublethal effects of toxic organic compounds on fish.
Gaps in telecommunications public policy: end to end service delivery in the NBN world
Creators: name: Rocke, Mike

description: The future success of telecommunications service providers will depend critically on achieving end-to-end performance that meets the reasonable expectations of customers for services carried over IP-based packet switched, multi-services, multi-carrier networks. In the Australian context the NBN will be a fundamental part of the IP based next generation networks. Agreed end-to-end performance standards for IP based networks have been established by both international and Australian regulatory and standards organisations. However standards for the allocation of the 'QoS budget' between segments provided by different carriers for the various parameters comprising those performance standards have yet to be adequately developed. While the importance of such standards is recognised, progress in this regard is very slow. The need for action by the appropriate authorities both in Australia and internationally is rapidly becoming critical to enable network suppliers, including but not limited to NBN Co, to build complying networks in a timely fashion.

description: Background: Gene expression changes in the structural cells of the airways are thought to play a role in the development of asthma and airway hyperresponsiveness. This includes changes to smooth muscle contractile machinery and epithelial barrier integrity genes. We used a targeted gene expression arrays to identify changes in the expression and co-expression of genes important in asthma pathology. Methods: RNA was isolated from the airways of donor lungs from 12 patients with asthma (8 fatal) and 12 non-asthmatics controls and analyzed using a multiplexed, hypothesis-directed platform to detect differences in gene expression. Genes were grouped according to their role in airway dysfunction: airway smooth muscle contraction, cytoskeleton structure and regulation, epithelial barrier function, innate and adaptive immunity, fibrosis and remodeling, and epigenetics. Results: Differential gene expression and gene co-expression analyses were used to identify disease associated changes in the airways of asthmatics. There was significantly decreased abundance of integrin beta 6 and Ras-Related C3 Botulinum Toxin Substrate 1 (RAC1) in the airways of asthmatics, genes which are known to play an important role in barrier function. Significantly elevated levels of Collagen Type 1 Alpha 1 (COL1A1) and COL3A1 which have been shown to modulate cell proliferation and inflammation, were found in asthmatic airways. Additionally, we identified patterns of differentially co-expressed genes related to pathways involved in virus recognition and regulation of interferon production. 7 of 8 pairs of differentially co-expressed genes were found to contain CCCTC-binding factor (CTCF) motifs in their upstream promoters. Conclusions: Changes in the abundance of genes involved in cell-cell and cell-matrix interactions could play an important role in regulating inflammation and remodeling in asthma. Additionally, our results suggest that alterations to the binding site of the transcriptional regulator CTCF could drive changes in gene expression in asthmatic airways. Several asthma susceptibility loci are known to contain CTCF motifs and so understanding the role of this transcription factor may expand our understanding of asthma pathophysiology and therapeutic options.
Assessment of functional knee bracing: An in vivo three-dimensional kinematic analysis of the anterior cruciate deficient knee.
Creators: name: Ramsay, Dan.

Year: 1999
Subjects: subject: Health Sciences, Rehabilitation and Therapy.

description: The aim of this investigation was to determine whether application of a functional brace reduced rotational and linear tibial displacements during the performance of a One Legged Jump (OLJ). Steinmann traction pins were surgically implanted into the femur and tibia of six young normal healthy subjects having either a partial or complete anterior cruciate ligament (ACL) rupture. Stereophotogrammetric radiographs (RSA) were taken once target markers were affixed to the pins. Angular and translation measurements were recorded using the MacReflex motion analysis system sampling at 120 Hz. A Kistler force plate was synchronised to collect ground reaction forces simultaneously at 960 Hz. Patients were required to jump for distance to sufficiently stress the ACL. Subjects were randomly assigned to start with either the braced or unbraced condition. Analysis focused on differences in magnitudes and changes in the shape of the curves between bracing conditions.

Subjects: subject: Engineering, Biomedical.

description: A novel approach was used to synthesize bioactive polyurethanes by applying polypropylenimine octaamine dendrimers as the chain extenders, while another approach trying to incorporate star PEO (polyethylene oxide) directly into polyurethane failed to attain appropriate polymers. A protection/deprotection strategy was used to incorporate the dendrimers into the polyurethane chains, then PEO was chemically attached after deprotection to increase the biocompatibility of the material. A generation 2.0 polypropylenimine octaamine dendrimer which has eight arms ending with amine groups, was used for the modification. The dendrimers were protected using the N-hydroxy-succinimide ester of a tert-butyloxycarbonyl (tBOC)-protected alanine or 9-Fluorenylmethyloxycarbonyl chlorocarbonate (Fmoc) in methylene chloride-triethylamine. A molar ratio of 6:1 (protecting group:dendrimer) was used to get a statistical distribution of protected dendrimers in which most of the dendrimers would have 6 arms protected. The partially protected dendrimers were used with ethylene diamine (ED) or butanediol (BDO) as a chain extender (molar ratio of dendrimer ED/DO = 1:9) to produce the dendrimer modified polyurethanes. After deprotection of the dendrimers, PEG-SPA (Polyethylene Glycol-Succinimidyl Propionate) was used to attach PEO to the polyurethane chains. (Abstract shortened by UMI.)
Patrick Straram et l'utopie urbaine situationniste.

Subjects: subject: Geography.

description: This research offer a new perspective on the life and works of Patrick Straram in light of situationism. The association of Straram with the Quebec counter-cultural movement has overshadowed the profound influence of situationism on his life and works. Having participated to the foundation of the Internationale lettriste and introduce situationism in Quebec, he will pursue the situationist project throughout his existence. The situationist project correspond to a way of life base on the transformation of daily life and the urban environment in order to liberate the individual from the society of spectacle of modern capitalism. The situations urban vision differ from other architectural avant-garde due to it's cultural and artistic aspects inherited from the avant-garde movement of the 20th century (dadaism, futurism and surrealism). The cultural activities and the works of Straram are characterized by a critic of daily life, the integration of art and the transformation/appropriation of urban spaces necessary to the construction of situations. This research demonstrate that these various aspects correspond to the urban vision of the Internationale situationniste in regard to cultural and political actions. The analysis Straram's urban vision is base on the concept of unitary urbanism and its various components (detournement, derive, psychogeographie and construction of situations). Straram life and cultural productions constitutes a living critic of the rational city and represent a rare form of expression of the situationist urban utopia in North America. This thesis also demonstrate that many aspects of the urban and architectural theories of the Internationale situationniste continues to be incorporate in the contemporary urban and virtual environment.

description: We present the largest homogeneous survey of z > 4.4 damped Lyα systems (DLAs) using the spectra of 163 QSOs that comprise the Giant Gemini GMOS (GGG) survey. With this survey we make the most precise high-redshift measurement of the cosmological mass density of neutral hydrogen, ΩHI. At such high redshift, important systematic uncertainties in the identification of DLAs are produced by strong intergalactic medium absorption and QSO continuum placement. These can cause spurious DLA detections, result in real DLAs being missed or bias the inferred DLA column density distribution. We correct for these effects using a combination of mock and higher resolution spectra, and show that for the GGG DLA sample the uncertainties introduced are smaller than the statistical errors on ΩHI. We find ΩHI = 0.98-0.18+0.20 × 10-3 at 〈z〉 = 4.9, assuming a 20 per cent contribution from lower column density systems below the DLA threshold. By comparing to literature measurements at lower redshifts, we show that ΩHI can be described by the functional form ΩHI(z) ∝ (1+z)0.4. This gradual decrease from z = 5 to 0 is consistent with the bulk of Hα. i gas being a transitory phase fuelling star formation, which is continually replenished by more highly ionized gas from the intergalactic medium and from recycled galactic winds.

description: The use of autologous cells harvested and subsequently transplanted in an intraoperative environment constitutes a new approach to promote regeneration. Usually cells are isolated by selection methods such as fluorescence- or magnetic- activated cell sorting with residual binding of the antibodies or beads. Thus, cell-based therapies would benefit from the development of new devices for cell isolation that minimally manipulate the target cell population. In the clinic, 5 to 10 percent of fractures do not heal properly and CD31+ cells have been identified as promising candidates to support bone regeneration. The aim of this project was to develop and prototype a simple system to facilitate the enrichment of CD31+ cells from whole blood. After validating the specificity of a commercially available aptamer for CD31, we combined this aptamer with traditional magnetic bead strategies, which led to enrichment of CD31+ cells with a purity of 91±10%. Subsequently, the aptamer was attached to agarose beads (Ø = 100–165 um) that were incorporated into a column-based system to enable capture and subsequent release of the CD31+ enriched cells. Different parameters were investigated to allow a biophysical- based cell release from beads, and a simple mixing was found sufficient to release initially bound cells from the optimized column without the need for any chemicals that promote disassociation. The system led to a significant enrichment of CD31+ cells (initial population: 63±9%, released: 87±3%) with excellent cell viability (released: 97±1%). The composition of the released CD31+ fraction indicated an enrichment of the monocyte population. The angiogenic and osteogenic potential of the released cell population were confirmed in vitro. These results and the simplicity of this system highlight the potential of such approach to enable cell enrichment strategies in intraoperative settings.

Musical Modernism

description: While developing my compositional practice over the last five years, I was influenced to innovate on my techniques because of my contact with the music of several key composers and through the reevaluation of musical modernism and large-scale musical form. Through current scholarship, I understand musical modernism as a broader artistic movement than is commonly misunderstood. Musical modernism is often taught as an un-intuitive practice where the composer designs an automaton which generates the entirety of a composition or that a single musical object, such as a twelve-tone row, is the sole source of the derivation of all musical elements within a work. Notions of a post-modern or post-serial music are often drawn from lack of understanding of the actual openness within the categories which they intend to negate. While some modernists present a rigorous and dogmatic philosophy, it is clear to me that it is necessary to categorize artists who use structure outside of a hegemonic framework. To describe this orientation, I take on a metaphor of magic or enciphering with the term "Rational Thaumaturgy." In preparing the analytic chapters of this dissertation, I undertook a serious intervention on my thinking about musical form. By broadening the content of analysis beyond traditional concepts of themes, harmony, or motivic development to the more abstract concept of "material," certain subtle relationships between musical moments across the timeline of a composition can be understood. Importantly, the concept of musical "materials" are often intentionally deployed by composers. To present my argument for both Rational Thaumaturgy and formal polyphony, or "variegated form," I performed analysis on works by several composers whose work has been highly influential on my own yet have little or no published scholarship in the English language or no published scholarship of any kind: Jean Barraqué's Sonate pour piano, Francisco Guerrero Marín's Rhea for 12 saxophones, and Trevor Bača's Akasha for string quartet. To analyze these works, I familiarized myself with non-English scholarship when it was available and I consulted primary-source sketch material. After identifying important features of these works, such as aspects of their large-scale form or their relationship to ideas of formalization, I describe two of my own works, Polillas for string quartet and Alu for sinfonietta, which share intentional similarities with the analyzed works.
La construction de l'altérité dans deux romans de Madeleine Monette.

description: Le Double Suspect et Amandes et Melon produisent l'impression d' embrasser des ombres , en limitant le lecteur à la perspective de personnages secondaires dans l'appréhension de Manon et de Marie-Paule, personnages-moteurs construits à partir des pensées qu'ils suscitent. Aussi, cette thèse cherche-t-elle à repérer et à analyser, dans le premier et le troisième roman de Madeleine Monette, les stratégies narratives qui président à la construction de l'altérité ou de ce que nous appelons la part toujours insaisissable du personnage de l'autre . Nous développons, pour l'analyse, une approche qui s'appuie sur une correspondance de concepts empruntés à Paul Ricoeur, à Mieke Bal et à Dorrit Cohn, tels que l'apprésentation et la focalisation, la transparence intérieure et l'opacité, le focalisé imperceptible et les modes de représentation de la vie psychique. Finalement, l'analyse de chaque roman permet d'identifier des constantes, des variantes et surtout deux métastratégies: celle du désaveu et celle du refus de la cohérence.
Concepts of marriage in the fiction of Virgina Woolf, Nella Larsen, and Dorothy Allison.

Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2000
Subjects: subject: Literature, Modern.

description: This thesis examines concepts of marriage in one representational work each by Virginia Woolf, Nella Larsen, and Dorothy Allison. I explore gender, race, class, sexual orientation, and female sexuality as categories governed by ideological impositions that in turn influence subjectivity and thus marital arrangements. I demonstrate that the characters' choice to submit to or to resist ideological constraints on these categories provide for an either open or closed concept of marriage. While Woolf proposes a performativity, or open concept of marriage, Larsen and Allison warn against marital performance, or a death-like/closed concept of marriage. The three authors show that their female characters' choices are limited as their existence in a patriarchal, racist, sexist, and heterosexist society grants them Selfhood (only) through marriage and married motherhood. Woolf, Larsen, and Allison illustrate clearly that to allow for an open subject formation it is necessary to de-ideologize the afore-mentioned categories, and to challenge destructive/closed concepts of marriage.

description: We present the discovery of a luminous unresolved H ii complex on the edge of dwarf galaxy GAMA J141103.98−003242.3 using data from the Sydney-AAO Multi-object Integral field spectrograph (SAMI) Galaxy Survey. This dwarf galaxy is situated at a distance of ∼100 Mpc and contains an unresolved region of H ii emission that contributes ∼70 per cent of the galaxy's Hα luminosity, located at the top end of established H ii region luminosity functions. For the H ii complex, we measure a star formation rate of 0.147 ± 0.041 M⊙ yr−1and a metallicity of 12+log(O/H) = 8.01 ± 0.05 that is lower than the rest of the galaxy by ∼0.2 dex. Data from the H i Parkes All-Sky Survey (HIPASS) indicate the likely presence of neutral hydrogen in the galaxy to potentially fuel ongoing and future star-forming events. We discuss various triggering mechanisms for the intense star formation activity of this H ii complex, where the kinematics of the ionized gas are well described by a rotating disc and do not show any features indicative of interactions. We show that SAMI is an ideal instrument to identify similar systems to GAMA J141103.98−003242.3, and the SAMI Galaxy Survey is likely to find many more of these systems to aid in the understanding of their formation and evolution.

description: The key to multi-service platform performance with QoS support is to provide appropriate switching and scheduling mechanisms at various contention points in a network. In this thesis, we focus on the two key elements in any traffic scheme: switching and scheduling. We introduce innovative switching architecture and scheduling algorithms designed to keep them in line with network operations. In ATM networks, we propose per-VC queueing architecture and per-VC scheduling. In IP networks, we propose per-flow queueing in access routers and VC-merge in core routers to address the scalability issue. We also introduce per-flow scheduling in tandem to our switching architecture. We conduct performance analysis to evaluate the performance of our proposed switching and scheduling schemes. Simulations are used to validate our analytical results.

description: Background: We used High Resolution – peripheral Quantitative CT (HR-pQCT) imaging to examine peri-articular bone quality in early rheumatoid arthritis (RA) and explore whether bone quality improved over 12-months in individuals receiving care consistent with practice guidelines. Methods: A 1-year longitudinal cohort study (Baseline and 12-months) evaluating individuals with early RA compared to age/sex-matched peers. Personal demographic and health and lifestyle information were collected for all. Whereas, active joint count (AJC28), functional limitation, and RA medications were also collected for RA participants. HR-pQCT imaging analyses quantified bone density and microstructure in the Metacarpal Head (MH) and Ultra-Ultra-Distal (UUD) radius at baseline and 12-months. Analyses included a General Linear Modelling repeated measures analyses examined main effects for disease, time, and interaction on bone quality. Results: Participants (n = 60, 30 RA/30 NRA); 80% female, mean age 53 (varying from 21 to 74 years). At baseline, RA participants were on average 7.7 months since diagnosis, presenting with few active joints (AJC28: 30% none, remaining 70% Median 4 active joints) and minimal self-reported functional limitation (mHAQ-DI0–3: 0.56). At baseline, 29 of 30 RA participants had received one or more non-biologic disease-modifying anti-rheumatic drugs (DMARD);13 in combination with glucocorticoid and 1 in combination with a biologic medication. One participant only received glucocorticoid medication. Four RA participants withdrew leaving 26 pairs (n = 52) at 12-months; 23 pairs (n = 46) with UUD and 22 pairs (n = 44) with MH baseline and 12-month images to compare. Notable RA/NRA differences (p < 0.05) in bone quality at all three sites included lower trabecular bone density and volume, more rod-like trabeculae, and larger and more variable spaces between trabeculae; fewer trabeculae at the UUD and MH2 sites; and lower cortical bone density and volume in the MH sites. Rate of change over 12-months did not differ between RA/NRA participants which meant there was also no improvement over the year in RA bone quality. Conclusions: Early changes in peri-articular bone density and microstructure seen in RA are consistent with changes more commonly seen in aging bone and are slow or resistant to recover despite well controlled inflammatory joint symptoms with early DMARD therapy.

description: Effects of the transition to high school on students' beliefs and attitudes about mathematics were investigated in the present longitudinal study. The influence of students' math grades, competence beliefs, and values before making the transition, as well as changes in these beliefs and values across the transition, on their math grades and enrolment intentions were examined across Grades 8, 9, and 10. Based on the theoretical framework of Eccles and colleagues' model of achievement (Wigfield & Eccles, 2000), two path analytic models were tested for boys and girls separately on data collected from the same students across Grades 8, 9, and 10 (ns = 290, 265, and 249 for boys; 311, 278, and 255 for girls, respectively). Short-term effects were assessed on students' math grades and math enrolment intentions in Grade 9 (Model 1) and longer-term effects on these same variables in Grade 10 (Model 2). On average, students as a group showed declines in their math competence beliefs, their perceived usefulness and intrinsic valuing (boys only) of math, and in their math grades across the three years. Conversely, students' math enrolment intentions increased across this same period. Changes in stability were only found for boys' math utility value (increase) and girls' math competence beliefs (decrease). Results of path analyses indicated that, across both models, changes in math competence beliefs directly predicted boys and girls' math grades and girls' math enrolment intentions, beyond the direct effects of their math competence beliefs in Grade 8 (e.g., before making the transition to high school). Changes in math values predicted directly students' math enrolment intentions, also beyond the effects of their values for math in Grade 8 (before the transition). Although there were many similarities in the Models across gender, some noteworthy differences in the continuity of and relations between these variables for boys and girls' are discussed. In both models, changes in math competence beliefs predicted directly changes in math values across the same time periods. Results of Model 1 supported a direction of causality from math competence beliefs to math values Results of Model 2 were inconclusive in this regard. This study has provided support for the key relations between math grades and math-related competence beliefs, values, and enrolment intentions. It has also extended previous research by examining empirically the influence of actual changes that are occurring in students' math competence beliefs and values for math across and after the transition to high school.

Subjects: public abstract

description: Why do some countries fail to immunize their populations? Why, despite their natural reluctance to pay taxes, do people pay taxes? What can improve immunization rate and tax compliance attitudes? The conventional response to these questions points to failures of state capacity, the inability of bureaucracies to carry out policy and collect taxation. I argue that to fully understand policy outcomes and compliance attitudes, we need to look beyond the characteristics of the state itself and consider the roles that societal attitudes, and specifically trust, play in governance.
description: I further argue, regarding policies where the state and society share the same interest, such as vaccination, then political trust, both trust in representational institutions (parliament, party, government) and trust in implementing institutions (court, police, civil service, and agencies) should be most important. But for policies where the interests of state and society have a fundamental tension, such as taxation, the development of democratic institutions shapes the role of generalized trust (toward unknown or out-group people) in tax compliance attitudes.
description: I find that trust in implementing institutions has the most considerable effect on vaccination coverage and that people who trust in others are less willing to pay taxes in less democratic countries. By demonstrating the role of trust in policy outcomes and compliance attitudes, my research implies that improving the quality of bureaucracy, and the accountability as well as inclusiveness of political institutions, will prepare governments for governance challenges like future pandemics and climate change.

description: We present the Early Data Release of the Sydney-AAO Multi-object Integral field spectrograph (SAMI) Galaxy Survey. The SAMI Galaxy Survey is an ongoing integral field spectroscopic survey of ~3400 low-redshift (z<0.12) galaxies, covering galaxies in the field and in groups within the Galaxy And Mass Assembly (GAMA) survey regions, and a sample of galaxies in clusters. In the Early Data Release, we publicly release the fully calibrated datacubes for a representative selection of 107 galaxies drawn from the GAMA regions, along with information about these galaxies from the GAMA catalogues. All datacubes for the Early Data Release galaxies can be downloaded individually or as a set from the SAMI Galaxy Survey website. In this paper we also assess the quality of the pipeline used to reduce the SAMI data, giving metrics that quantify its performance at all stages in processing the raw data into calibrated datacubes. The pipeline gives excellent results throughout, with typical sky subtraction residuals in the continuum of 0.9-1.2 per cent, a relative flux calibration uncertainty of 4.1 per cent (systematic) plus 4.3 per cent (statistical), and atmospheric dispersion removed with an accuracy of 0.'09, less than a fifth of a spaxel.

description: This thesis was aimed at exploring a few selected aspects of manganese chemistry with a particular emphasis on the unconventional reactivity for this metal. Firstly, appropriate organomanganese complexes have been prepared and fully characterized. The majority of these species stemmed from our development of the effective reagent [Mn(CH2SiMe3)2(THF)] 2 which was used as starting material in ligand metathesis reactions with protic organic ligands. Two such ligands specifically designed for this purpose were the hemi-labile N-MeDipyrrole and N-MeTripyrrole ligands. These ligand systems, and various others, allowed for the synthesis of several model systems to mimic the water oxidation reaction of the OEC in Photosystem II. One such ligand (tartaric acid) formed the complex [Mn(mu3,eta 2-O2CCH(O)CH(O)CO2)(H2O)0.5]·H 2O1.5 which evolves oxygen upon addition of a strong oxidizing agent, thus indicating the oxidation of water. In another practical application for Mn(II) complexes we probed the analogy between the high spin d5 electronic configuration with the d10 electron configuration of Zn by finding for the first time Mn complexes capable of acting as catalysts in the co-polymerization of CO2 with an epoxide, producing nearly perfectly alternating polycarbonate. These findings prove that Mn is capable of catalyzing a reaction which is normally only performed by the late transition metal Zn. Similarly, we probed the behavior of Mn complexes of the bis-iminato pyridine ligand system which so effectively supports ethylene polymerization with a variety of metals. Our research into the reduction of Mn(II) complexes has led to the formation of the formally monovalent [(BisImine)MnCl(THF)] complex. At the end of the thesis we have taken advantage of the synthesis of the novel hemi-labile pyrrolide ligands for the preparation of chromium catalysts for selective ethylene trimerization reaction. The main task was to elucidate the factors which determine selectivity in the oligomerization process. At this preliminary stage we targeted the issue of metal oxidation state. It was found that both Cr(II) and Cr(III) complexes of this ligand were highly active for the production of 1-hexene, but yielded a Shultz-Flory distribution of alpha-olefins. In addition, various imine-based ligands in conjunction with Cr(II) were also found to produce statistical distributions of alpha-olefins. This work led us to revisit the selective processes published in the literature with known SNS and PNP-based compounds of both Cr(II) and Cr(III) . Overall, we were unable to unequivocally identify which oxidation state led to the selective formation of 1-hexene, our results instead indicated that selectivity might be entirely ligand-based and independent of the actual oxidation state.

description: The dissertation discusses the possibility of a reconciliation between neo-Kaleckian and classical (neo-Marxian/Sraffian) two-sector growth models, and it explores the issues relative to the long-run convergence of actual degrees of capacity utilization towards their normal values. In a simplified analytical framework, that examines regimes incorporating neo-Kaleckian and neo-Marxian/Sraffian perspectives, the thesis shows that the paradox of thrift and the paradox of costs hold both in the short run and in the long run. A more sophisticated two-sector Kaleckian model is also developed within a stock-flow consistent framework that includes conflicting-claim inflation and Kaldorian technical progress. Simulation results show that inflation-targeting policies based on the so-called 'Taylor rule' could remove the long-run paradoxes, leading to economic depression. These policies also fail to achieve normal rates of capacity utilization, because of 'path-dependency', in contrast to the arguments put forth by some neo-Marxists and the proponents of the neoclassical New Consensus. Furthermore, our empirical tests show that the Phillips curve has a horizontal segment within a large intermediate range of capacity utilization rates, using Canadian data over the last two decades. This horizontal Phillips curve implies that the adjustment mechanisms suggested by classical models just may not exist in reality during this time period. Therefore, the thesis offers some justification for using simple neo-Kaleckian growth models where effective demand plays a crucial role in the determination of capacity utilization, employment and growth, both in the short run and in the long run, and it suggests the use of expansionary fiscal policy and monetary policy as long as the economy remains within the intermediate range of capacity utilization. Key words: Two-Sector Growth Model; Long-Run Convergence; Paradox of Thrift; Paradox of Costs; Inflation; Phillips Curve; Monetary Policy; Stock-Flow Consistent Approach.

description: We present a methodology for the regularisation and combination of sparse sampled and irregularly gridded observations from fibre-optic multi-object integral-field spectroscopy. The approach minimises interpolation and retains image resolution on combining sub-pixel dithered data. We discuss the methodology in the context of the Sydney-AAO Multi-object Integral-field spectrograph (SAMI) Galaxy Survey underway at the Anglo-Australian Telescope. The SAMI instrument uses 13 fibre bundles to perform high-multiplex integral-field spectroscopy across a one degree diameter field of view. The SAMI Galaxy Survey is targeting 3000 galaxies drawn from the full range of galaxy environments. We demonstrate the subcritical sampling of the seeing and incomplete fill factor for the integral-field bundles results in only a 10% degradation in the final image resolution recovered. We also implement a new methodology for tracking covariance between elements of the resulting datacubes which retains 90% of the covariance information while incurring only a modest increase in the survey data volume.

description: The beluga whale is a cetacean that inhabits arctic and subarctic regions, and is the only living member of the genus Delphinapterus. The genome of the beluga whale was determined using DNA sequencing approaches that employed both microfluidic partitioning library and non-partitioned library construction. The former allowed for the construction of a highly contiguous assembly with a scaffold N50 length of over 19 Mbp and total reconstruction of 2.32 Gbp. To aid our understanding of the functional elements, transcriptome data was also derived from brain, duodenum, heart, lung, spleen, and liver tissue. Assembled sequence and all of the underlying sequence data are available at the National Center for Biotechnology Information (NCBI) under the Bioproject accession number PRJNA360851A.

public abstract

description: Title IX of the Education Amendments (Title IX), the Jeanne Clery Disclosure of Campus Security Policy and Campus Crime Statistics Act (Clery Act), and their subsequent updates inform how federally funded institutions of higher education (IHEs) are expected to report, prevent, and respond to sexual misconduct.
description: The Clery Act is a consumer protection policy and relates most directly to institutional reporting. A 2013 amendment required institutions to publish counts of sexual misconduct reported to campus police. Aim one of this work assesses whether data yielded from this requirement is representative of the volume of sexual misconduct an institution is made aware of. Findings of descriptive longitudinal analysis suggest the Clery Act is not achieving its intended transparency purpose.
description: Implementing Title IX has been a challenge for IHEs due to four considerable changes to the policy in the last decade. Aim two applied a synthetic control approach to understand if and how recent Title IX iterations impact rates of sexual misconduct reports to an IHE. Findings suggest reporting behaviors are marginally impacted by what iteration of Title IX is informing institutional response processes.
description: Aim three applied flexible coding to in-depth interviews with Title IX Coordinators to understand the consequences of the most recent Title IX iteration. Current investigation processes were perceived as unnecessarily rigid, time consuming, expensive, and stressful. The pseudo-court processes imposed per this iteration reportedly carry flawed legal arguments, and conflict with IHEs educational missions. Informal resolutions offered a new intervention pathway perceived as more tailorable to preventing future harm.
