Translating into a non-native dialect: A corpus-based investigation
Creators: name: Gomez Palou, Marta
Publisher: name: Université d'Ottawa / University of Ottawa

Subjects: subject: Language, General.

description: Traditionally, translators have been encouraged to translate only into their mother tongue; however, this premise is being increasingly challenged in the translation literature. This thesis explores the related issue of translators working not into a foreign language, but into a foreign dialect. In particular, the dual objective of this thesis is first to demonstrate that corpora and corpus analysis tools provide a viable means for investigating and describing dialects, and second to determine whether a specially designed monodialectal corpus can be a useful resource for helping translators to produce adequate target texts in a non-native dialect. To meet these goals, two different yet related experiments are conducted. The first consists of a comparison between the textbook descriptions of the bonaerense dialect used in the Buenos Aires region of Argentina and the actual linguistic features present in a corpus consisting of authentic texts written in this dialect. The results reveal disparity between the textbook descriptions and the corpus contents, proving that a corpus is a versatile resource that can be used to learn more about dialects. The second experiment consists of a comparison of two sets of translations into bonaerense prepared by a group of translators from Spain. The first set of translations is carried out using conventional non-corpus-based resources (e.g. term banks, dictionaries), while the second set is produced using the above-mentioned monodialectal corpus of bonaerense. The results of this second experiment provide evidence suggesting that a monodialectal corpus can indeed facilitate the production of a target text in a non-native dialect.

The application of categorical regression to model the exposure-response relationship of copper excess and deficiency
Creators: name: Chambers, Andrea
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2010
Subjects: subject: Health Sciences, Toxicology.
subject: Health Sciences, Epidemiology.

description: There is a need to define an exposure-response curve for both copper excess and deficiency to assist in defining the acceptable range of oral intake. A copper exposure-response database has been developed where response data has been assigned to ordinal severity scores. A generalized linear model was used to estimate the probability of response associated with dose, duration and severity. The exposure-response model is defined to account for differences in animal species, route of exposure and age. The exposure-response curves for copper excess and copper deficiency have defined an optimal intake level of 2.0 mg Cu/day and an acceptable range of oral intake between 1.8 and 3.1 mg Cu/day. These results suggest that current recommendations for copper intake including the recommended dietary intake (0.9 mg/day) and the tolerable upper intake level (10 mg/day) may not protect the population from responses that might occur outside the limits of the homeostatic range.
Fault localization for next generation survivable all-optical networks
Creators: name: Khair, Mazen George
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2008
Subjects: subject: Engineering, Electronics and Electrical.

description: We propose a distributed fault localization protocol, called Parallel Limited Perimeter Vector Matching (P-LVM) protocol, for localizing multi-link failures in all-optical networks. The P-LVM protocol is based on the Limited Perimeter Vector Matching (LVM) protocol for localizing single-link failures. To handle multi-link failures, it tries to separate each failure in a small perimeter area after identifying each perimeter area with its corresponding failure and then localize the failures in parallel respectively in a distributed manner. Through simulation results, we show that the P-LVM protocol can effectively localize multi-link failures that occur simultaneously or at different times. We also study the optimization problems in applying the LVM protocol in static all-optical networks. We consider two optimization problems: one is to optimize the traffic distribution so that the fault localization probability in terms of the number of localized links is maximized and the other is to optimize the traffic distribution so that the time for localizing a failed link is minimized. We formulate the two problems into an integer linear programming problem, respectively, and use the CPLEX optimization tool to solve the problems. By optimizing the traffic distribution the fault localization probability can be maximized and the fault localization time can be minimized. Moreover, a heuristic algorithm is proposed to evaluate the optimization results through simulation experiments. Finally, we propose two different fault localization protocols for localizing single-link failures in multi-domain all-optical networks. These two protocols are based on LVM protocol mechanism, which restricts fault localization within a smaller perimeter area and can thus significantly reduce the time and space complexity for fault localization. The first protocol assumes the existence of power monitoring only at edge nodes, whereas the second protocol assumes no power monitors at the intermediate nodes or the edge nodes. The two protocols can localize both inter-domain and intra-domain link failures without exchanging any internal confidential domain-specific information between different domains. The analytical results show that both protocols can not only fast localize an inter-domain link failure between different domains but also localize an intra-domain link failure that affects inter-domain traffic faster than the Open-Shortest-Path-First (OSPF) protocol in a large network.

description: Background: Systematic review methodology includes the rigorous collection, selection, and evaluation of data in order to synthesize the best available evidence for health practice, health technology assessments, and health policy. Despite evidence that sex and gender matter to health outcomes, data and analysis related to sex and gender are frequently absent in systematic reviews, raising concerns about the quality and applicability of reviews. Few studies have focused on challenges to implementing sex/gender analysis within systematic reviews. Methods A multidisciplinary group of systematic reviewers, methodologists, biomedical and social science researchers, health practitioners, and other health sector professionals completed an open-ended survey prior to a two-day workshop focused on sex/gender, equity, and bias in systematic reviews. Respondents were asked to identify challenging or ‘thorny’ issues associated with integrating sex and gender in systematic reviews and indicate how they address these in their work. Data were analysed using interpretive description. A summary of the findings was presented and discussed with workshop participants. Results Respondents identified conceptual challenges, such as defining sex and gender, methodological challenges in measuring and analysing sex and gender, challenges related to availability of data and data quality, and practical and policy challenges. No respondents discussed how they addressed these challenges, but all proposed ways to address sex/gender analysis in the future. Conclusions Respondents identified a wide range of interrelated challenges to implementing sex/gender considerations within systematic reviews. To our knowledge, this paper is the first to identify these challenges from the perspectives of those conducting and using systematic reviews. A framework and methods to integrate sex/gender analysis in systematic reviews are in the early stages of development. A number of priority items and collaborative initiatives to guide systematic reviewers in sex/gender analysis are provided, based on the survey results and subsequent workshop discussions. An emerging ‘community of practice’ is committed to enhancing the quality and applicability of systematic reviews by integrating considerations of sex/gender into the review process, with the goals of improving health outcomes and ensuring health equity for all persons.
Coupling of single organic molecules to photonic micro-structures

description: Dopant molecules in organic crystals can be triggered to create single photons with certainty. This basic principle is currently being leveraged to develop a new generation of photonic components capable of delivering single photons to optical hardware. In turn, these single-photon sources are enabling increasingly sophisticated technologies based on the quantum nature of photons, in areas such as quantum computation and quantum cryptography. Dopant molecules in organic crystals can be triggered to create single photons with certainty. This basic principle is currently being leveraged to develop a new generation of photonic components capable of delivering single photons to optical hardware. In turn, these single-photon sources are enabling increasingly sophisticated technologies based on the quantum nature of photons, in areas such as quantum computation and quantum cryptography. In this thesis, I present my work towards realising an organic single-photon source using dibenzoterrylene (DBT) molecules in anthracene crystals. To realise a deterministic single-photon source with molecules, we have to address two main challenges. First, it is necessary to collect all the photons emitted by a single molecule into a propagating optical mode. To achieve this, I have investigated methods to place single DBT molecules close to the field maximum of single-mode waveguides. I describe our strategy which consists of overlaying microfluidic channels on top of silicon-nitride ridge waveguides. With this geometry, targeted crystallisation of DBT-doped anthracene occurs in small gaps running across the waveguides. We probe the system using coherent single-molecule spectroscopy and estimate that 7% of the molecular emission is coupled to the waveguide modes for one of our fabricated devices. The second challenge is to turn DBT molecules into coherent two-level systems. The vibrational spectrum of DBT prevents the system from generating indistinguishable single-photons without filtering of the emission. However, the reduction in single-photon efficiency due to filtering can be improved by selectively accelerating the radiative decay of the zero-phonon line. I discuss how such an enhancement is possible using optical cavities and how both challenges can be addressed with this approach. Finally, I introduce a new design for a vertically-emitting cavity with an active layer of DBT-doped anthracene.

description: Background: It is important to understand Canadians' expectations of health care services and the costs of delivering care in the Emergency Department (ED) in order to continue to provide health care in a sustainable manner. Objectives: To examine the reasons patients present to the ED, and to conduct a cost analysis to compare the costs of seeking care in the ED versus a primary care setting. Methodology: We surveyed patients (n=606) triaged to the cubicles of the ED of The Ottawa Hospital, Civic Campus. The survey asked about their perceived urgency level and their patterns of health service use. Patient surveys were accompanied by physician surveys to assess each patient's level of urgency from a medical perspective. We performed bivariate analysis and logistic regression on survey variables of interest. We also conducted a cost analysis to determine the costs of providing non-urgent care in the ED. Results: Both a presenting symptom of a musculoskeletal injury (OR=2.93, CI 1.42-6.04) and having heard of TeleHealth Ontario (OR=2.08, CI1.08-4.03) were significantly associated with non-urgent ED use from the patient perspective. We also found that non-urgent ED visits cost an average of $248.75, which is significantly more costly than a primary care visit. Implications: Our results provide insights regarding patient factors influencing ED use and relative costs of non-urgent ED visits versus outpatient family doctor visits. However, additional work may be required to identify non-medical factors influencing patient motivations for seeking care in the ED.
Real-Time Virtual Viewpoint Generation on the GPU for Scene Navigation

Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2010
Subjects: subject: Computer Science.

description: In this thesis we present a method for achieving real-time view interpolation in a virtual navigation application that uses a collection of pre-captured panoramic views as a representation of the environment. In this context, viewpoint interpolation is essential to achieve smooth and realistic viewpoint transition while the user is moving from one panorama to another. In this proposed approach, view interpolation is achieved by first computing the optical flow field between a pair of adjacent panoramas. This flow field can then be used by the view morphing algorithm to generate, on-the-fly, virtual viewpoints in-between existing views. Realistic interpolation is obtained by taking into account both scene geometry and color information. To achieve real-time viewpoint interpolation, a GPU implementation of the viewpoint interpolation algorithm has been developed. We ran our algorithm on multiple interior and exterior scenes and we were able to produce smooth and realistic viewpoint transitions by generating virtual views at a rate of more than 300 Panoramas per second.
"Summorum Pontificum" and the use of the extraordinary form of the Roman Rite: A canonical analysis in light of the current liturgical law
Creators: name: Glendinning, Chad J
Publisher: name: Université d'Ottawa / University of Ottawa

Subjects: subject: Canon Law.

description: On 7 July 2007, Pope Benedict XVI promulgated new ecclesiastical legislation -- the Apostolic Letter motu proprio Summorum Pontificum -- which allows general use of the 1962 Missale Romanum , in addition to the pre-conciliar liturgical rites for the administration of the sacraments of baptism, marriage, penance, the anointing of the sick, and confirmation. Although comprised of only twelve articles, the motu proprio occasions careful consideration in light of the ius vigens and important developments since the Second Vatican Council. Legal discrepancies are inevitable since the liturgical books permitted by Summorum Pontificum contain many norms which have been abrogated by later legislation. As all subsequent legislation is dependent upon the authentic teachings of the Second Vatican Council, the problems posed by Summorum Pontificum are of great concern to the science of canon law and the unity and good order of the Church itself. This study seeks to contribute to a deeper understanding of the legislative provisions of Summorum Pontificum within the context of post-conciliar liturgical reform. Specifically, the principal objective of this dissertation is to offer a canonical analysis of the provisions of Summorum Pontificum and assess the various challenges posed by the document. To achieve this objective, the thesis begins by providing the appropriate context in which to situate the latest provisions for use of the 1962 Missale Romanum and other earlier liturgical books, both antecedent (chapter one) and subsequent (chapter two) to the Second Vatican Council Opposition to the post-conciliar liturgical reform is identified and categorized for the purpose of understanding the proximate motivation of the motu proprio, just as earlier provisions are analyzed so to appreciate the unique characteristics of Summorum Pontificum itself (chapter three). The final two chapters are dedicated to a consideration of the provisions of Summorum Pontificum (chapter four), along with a resolution of a variety of disputed matters, such as the observance of abrogated liturgical discipline, and the incorporation of various post-conciliar legislative developments into earlier liturgical forms (chapter five).

description: La glycolyse anaérobique résulte en l'acidification du milieu extracellulaire et est associée à de multiples conditions physiologiques et pathologiques. La diminution du pH extracellulaire induit la détention de la protéine suppresseure de tumeurs VHL, une molécule impliquée dans la dégradation du facteur induit par l'hypoxie (HIF), dans le nucléole jusqu'au dégagement des protons. Ce processus est contrôlé par le signal de détention nucléolaire régulée par H+ (NoDS H+). Nous avons observé que le NoDSH+ de VHL possède des arginines méthylées à pH neutre qui diminuent l'affinité nucléolaire. Lors de l'accumulation d'ions H+ extracellulaires, la déméthylation des arginines du NoDSH+ induit la séquestration nucléolaire de VHL. Ce processus est réversé suite à la neutralisation du milieu acidique par la réméthylation des arginines et le relâchement de VHL du nucléole. Cette découverte est le premier exemple de la réversibilité de la méthylation des arginines régulée par une constante physiologique et contrôlant un processus cellulaire, la séquestration nucléolaire.

description: Background: Genome-wide sensitivity screens in yeast have been immensely popular following the construction of a collection of deletion mutants of non-essential genes. However, the auxotrophic markers in this collection preclude experiments on minimal growth medium, one of the most informative metabolic environments. Here we present quantitative growth analysis for mutants in all 4,772 non-essential genes from our prototrophic deletion collection across a large set of metabolic conditions. Results The complete collection was grown in environments consisting of one of four possible carbon sources paired with one of seven nitrogen sources, for a total of 28 different well-defined metabolic environments. The relative contributions to mutants' fitness of each carbon and nitrogen source were determined using multivariate statistical methods. The mutant profiling recovered known and novel genes specific to the processing of nutrients and accurately predicted functional relationships, especially for metabolic functions. A benchmark of genome-scale metabolic network modeling is also given to demonstrate the level of agreement between current in silico predictions and hitherto unavailable experimental data. Conclusions These data address a fundamental deficiency in our understanding of the model eukaryote Saccharomyces cerevisiae and its response to the most basic of environments. While choice of carbon source has the greatest impact on cell growth, specific effects due to nitrogen source and interactions between the nutrients are frequent. We demonstrate utility in characterizing genes of unknown function and illustrate how these data can be integrated with other whole-genome screens to interpret similarities between seemingly diverse perturbation types.
New roles for an old giant: Novel interactions of the dystonin protein
Creators: name: Bhanot, Kunal

Year: 2010
Subjects: subject: Biology, Neuroscience.

description: Dystonin/Bpag1 is a large cytoskeletal plakin protein that contributes to the integrity and subcellular structure of various cell types. Loss of dystonin in mice results in neuromuscular dysfunction and early death in a mouse mutant called dystonia musculorum. The phenotype in these mice is a result of sensory neuropathy causing abnormal posturing, uncoordinated muscle movements and poor muscle tone. The multi-domain structure of dystonin isoforms allows for their participation in numerous cell-specific interactions. Previous characterization of the non-epithelial dystonin proteins has focused on the alternatively spliced N-terminal actin-binding domain and the C-terminal microtubule-binding domain. Interactions of the family-defining plakin domain, however, have not been explored in detail. We therefore hypothesised that the plakin domain of neuronal dystonin (dystonin-a) interacts with a number of cytoplasmic and nuclear proteins and ultimately determines the function of these molecules in a cell-type specific manner. To this end, a pull-down interaction approach was utilized and several candidate interacting partners were identified. The candidate partners were validated through co-immunoprecipitation, co-immunofluorescence and proximity ligation assays. Through these efforts CRMP2 and myosin IIB were identified as potential binding partners of neuronal dystonin. Additionally, MAP1B, a microtubule stabilizing protein, and c1athrin heavy chain, the major component of the c1athrin triskelion were also identified as strong interaction partners for dystonin-a. The current study proposes new avenues of exploration that may elucidate the functional role of this versatile cross-linker and highlight its involvement in the cytoskeletal and endo-exocytic pathways of the cell. We hope this will further facilitate our understanding of how cytoskeletal proteins affect and regulate various neurodegenerative disorders.

description: Background: Among a cohort of drug-using street-involved youth, we sought to identify the prevalence of reporting increases and decreases in illicit drug use due to their current housing status and to identify factors associated with reporting these changes. Findings: This longitudinal study was based on data collected between June 2008 and May 2012 from a prospective cohort of street-involved youth aged 14–26 in Vancouver, Canada. At semi-annual study follow-up visits, youth were asked if their drug use was affected by their housing status. Using generalized estimating equations, we identified factors associated with perceived increases and decreases in drug use attributed to housing status. Among our sample of 536 participants at baseline, 164 (31%) youth reported increasing their drug use due to their housing situation and 71 (13%) reported decreasing their drug use. In multivariate analysis, factors that were positively associated with perceived increases in drug use attributed to housing status included the following: being homeless, engaging in sex work and drug dealing. Regular employment was negatively associated with increasing drug use due to housing status. Among those who reported decreasing their drug use, only homelessness was significant in bivariate analysis. Conclusion: Perceived changes in drug use due to housing status were relatively common in this setting and were associated with being homeless and, among those who increased their drug use, engaging in risky income generation activities. These findings suggest that structural factors, particularly housing and economic opportunities, may be crucial interventions for reducing or limiting drug use among street-involved youth.

description: Altered regulation of the serotonin system is implicated in depression and anxiety. The 5-hydroxytryptamine 1A (5-HT1A) receptor is a major regulator of the serotonin system. We have previously identified a calcium-regulated transcription factor, Freud-1, which represses 5-HT1A receptor expression in neurons. Analysis of human Freud-1 amino acid sequence revealed the presence of two putative calcium calmodulin kinase (CaMK) phosphorylation sites. We demonstrate the ability of Freud-1 to be phosphorylated by CaMKII in vitro. Mutations of Freud-1 phosphorylation sites reduced CaMKII mediated phosphorylation. Furthermore, CaMKII phosphorylation inhibited binding of Freud-1 to the 5-HT1A promoter elements in vitro. In cells, CaMKIV induced phosphorylation of Freud-1 and prevented Freud-1 induced repressor activity. Freud-1 mutants prevented the inhibitory effect of CaMKIV on Freud-1 mediated repression of 5-HT1A receptor gene. Together these results implicate phosphorylation of Freud-1 by CaMK, in calcium-dependent regulation of 5-HT1A receptor expression, could participate in antidepressant actions to restore 5-HT1A receptor levels.
Handheld Wi-Fi applications in ambulance systems

description: This thesis describes the design and implementation of handheld Wi-Fi applications in ambulance systems, which propose a solution that allows ambulance staff to access remote resources in Emergent Medical Services (EMS) from any location, record life measurements on site by using handheld PCs, and transfer patients' life measurements to the Emergency Room (ER) on the way to the hospital. The handheld Wi-Fi applications aim to provide mobility and efficiency for ambulance staff when saving a life. The handheld Wi-Fi applications afford ambulance staff more flexibility and high performance in accessing and sharing the patient's life data between the ambulance centre and hospitals in time-sensitive circumstances. The handheld Wi-Fi applications provide instant information transportation support for both ambulance staff and healthcare staff. The patient's life measurements are received before the ambulance reaches the hospital.
Rotation, scaling and translation invariant digital image watermarking

Subjects: subject: Engineering, Electronics and Electrical.

description: Many digital image watermarking schemes have been proposed and are robust to common signal processing, such as compression and filtering. Geometric distortions, such as rotation, scaling, and translation (RST), are considered the most challenging attacks. This thesis is on RST invariant digital image watermarking. In this thesis, we introduce the fundamental theories and techniques necessary for RST invariant digital image watermarking, and briefly review the existing RST invariant image watermarking schemes. Then, we propose an image rectification scheme for RST invariant digital image watermarking. Rotation and scaling transformations in the spatial domain result in cyclical shifts in the log-polar domain, which is the log-polar mapping (LPM) of the magnitude of the Fourier spectrum of the image. We utilize this property to detect the rotation and scaling parameters by using a matching template and our new phase-only filtering method in the LPM domain. We employ the same strategy in the spatial domain to detect the translation parameters. This rectification scheme can detect RST parameters very accurately. (Abstract shortened by UMI.)

description: A reduction of a requirement-based test suite can be achieved without significantly reducing the fault-detection capabilities of the original test suite. This is done by eliminating all but one of the equivalent test cases from each class of equivalent test cases of the original test suite. A requirement-based reduction technique proposed in [1] uses EFSM dependency analysis to define classes of equivalent test cases. Two types of dependencies, namely control and data dependencies, are identified in an EFSM/SDL model. In this thesis, based on [1], we have proposed algorithms to generate interaction patterns of a test case w.r.t. a requirement under test, algorithms to compare interaction patterns and determine whether or not they are equivalent, and an algorithm to identify a set of interaction patterns (w.r.t. the requirement under test) that are not covered by any test case from a given test suite. Also, Test Suite Reduction (TSR) program has been developed based on these algorithms, which contributes towards object oriented testing. (Abstract shortened by UMI.)

description: Prader-Willi syndrome (PWS) is a rare disorder characterised by varying nutritional phases that occur throughout the lifespan, ranging from failure to thrive to hyperphagia. If uncontrolled, the imbalance between energy intake and expenditure results in obesity development and increased morbidity and mortality risk. Although measures of energy requirements for accurate nutrition assessment are vital, the evidence appears sparse and heterogeneous; hence, the aim of this review was to examine the available literature on energy expenditure predicted or measured using various methods in individuals with PWS. Studies were sought that presented methods and results on resting energy expenditure or basal metabolic rate. A narrative synthesis was completed to present the study characteristics and results. Methods of determining energy requirements included predictive equations and indirect calorimetry. Differences amongst ages, growth hormone therapy, fasting status, and measures in which results were presented were limitations to appropriately summarising and identifying trends in energy expenditure. Indirect calorimetry was identified as the most accurate method; however, it is not widely available in all settings. Further research is encouraged to support the development of valid and reliable predictive equations that will better inform and improve the efficiency of clinical practice in supporting people with PWS.
Nonlinear modelling and analysis of repaired and retrofitted shear walls

Subjects: subject: Engineering, Civil.

description: With advancements in seismic code provisions, mainly as a response to major earthquakes, important parameters such as ductility and energy dissipation have become central in design, resulting in additional detailing for shear walls and other seismic force resisting systems. Due to the large inventory of existing buildings lacking proper detailing for seismic resistance, cost-effective repair and retrofitting techniques have emerged to mitigate seismic risk and satisfy the requirements of current seismic codes. The finite element method (FEM) has emerged as a complementary analytical tool to investigate and assess various repair and retrofitting techniques. This research provides and validates nonlinear modelling procedures for the analysis of repaired and/or retrofitted shear walls using the FEM. Practical techniques including replacement of concrete, addition of reinforcing bars, external bonding of steel/FRP sheets and plates, addition of unbonded steel rods and plates with delay mechanisms, local replacement of concrete, and bolting of steel plates were investigated.
The impact of polarized MIMO channels in vehicular based communications

Subjects: subject: Engineering, Electronics and Electrical.

description: Measurements of orthogonally polarized MIMO channels were conducted in downtown Ottawa with dual-polarized receive array elements positioned along the sides of a measurement vehicle. The measured channel data are used to analyze characteristics of the polarized channel including the angular distribution of received power, diversity, correlation and cross-polarization discrimination. It is shown that if spatially separated antennas are replaced with dual-polarized elements the cross-polarization discrimination results in a performance loss that is partially compensated for by improved cross-polar correlation characteristics. Further, it is observed that the locations of the array elements at the mobile has a significant impact on the channel characteristics measured. In areas where the received signal energy is highly directional, the orientation of the vehicle with respect to the location of the transmitter often results in channels with characteristics which are significantly different from one side of the mobile to the other. This is further influenced by the presence (or lack thereof) of buildings, which can act as reflective signal sources for elements of the array shadowed by the vehicle.

description: Polyurethanes are versatile materials used in the manufacture of diverse medical devices. Monocytes attach to the material surface and differentiate to monocyte-derived macrophages (MDM)s during the foreign body response. MDMs degrade polyurethanes by releasing reactive oxygen species (ROS) and hydrolytic enzymes (cholesterol esterase and monocyte-specific esterase (MSE)) by an unknown mechanism. To study this mechanism, model polycarbonate-based polyurethanes (PCNU)s have been made with hexane (HDI) or methylene bisphenyl diisocyanate (MDI) with poly (1,6-hexyl carbonate) diol (PCN) and 1,4-butanediol (BD) in a 4:3:1 ratio of HDI:PCN:BD (HDI431) or a 3:2:1 ratio of HDI:PCN:BD or MDI:PCN:BD (HDI321 or MDI321 respectively). HDI431 is the most degradable by MDM- and esterase-mediated degradation followed by HDI321 and MDI321. Manuscript#1 investigated the effects of phorbol myristate acetate (PMA) on MDM-mediated degradation of model PCNUs. In this study PMA inhibited the degradation of HDI PCNUs correlating with decreased esterase activity and MSE, but had no effect on the degradation of MDI321. Manuscript#2 suggested that H2O 2 treatment degraded PCNUs and affected subsequent MDM-mediated degradation, esterase and acid phosphatase activity in a material surface specific manner. In addition, this study found that material surface stimulated ROS production in MDM. PMA affected ROS production in MDM differently based on material surface. Manuscript#3 investigated the role of protein kinase C (PKC) activation and the respiratory burst in MDM-mediated PCNU degradation. This study showed that the PMA inhibition of MDM-mediated degradation of HDI PCNUs, esterase activity and MSE protein were dependent on PKC activation. The activation marker high molecular weight group box 1 protein secretion was highest on HDI431 and was prevented by PMA, matching the decreased degradation. A degradative pathway in MDM on MDI321 was triggered with PKC inactive PMA, ROS scavengers or PMA with a PKC inhibitor. This thesis proposes that material degradation by hydrolytic and oxidative pathways are channeled by MDM in varying amounts depending on material chemistry, supporting the theory that MDM respond to material chemistry first and then to environmental factors. Therefore these studies suggest that each polyurethane be tested under physiologically appropriate conditions in order to determine if it is suitable for the desired application and implant location.

description: Size spectra in aquatic systems have shown a strong consistency of shape across a range of environmental conditions and among different groups of organisms, with higher normalized biomass of small organisms than large. Two main hypotheses have been proposed to explain this consistency in patterns. The energy hypothesis states that because of the inefficient transfer of energy between trophic levels, large organisms (as predators) have less energy available to them per unit habitat than small organisms. The habitat hypothesis states that space availability in the habitat shapes size spectra because small organisms perceive greater habitat space due to the presence of crevices and interstitial spaces that large organisms cannot access. My research examined body size spectra of organisms in 17 stream sites, testing both the energetic and habitat hypotheses for macroinvertebrates, crayfish, and fish. Body size research in lotic systems has rarely included all three groups of organisms, despite the potential importance of large organisms to ecosystem function. I developed a sampling method (electrobugging) to improve collection of large mobile macroinvertebrates; this method collected additional taxa and size classes not sampled by traditional methods. Slopes of size spectra including macroinvertebrates, crayfish, and fish were similar among sites. Large macroinvertebrates, crayfish, and fish contributed approximately half or more of the biomass in each site, while the contribution of small macroinvertebrates was negligible. To examine the habitat hypothesis, I developed a method to estimate habitat space from digital photographs of stream substrates by fitting organisms of different sizes to profiles extracted from the photos. Stable nitrogen isotopes were used to estimate trophic position and test the energetic hypothesis. The results of the test of both hypotheses suggested that both energy availability and space availability affected the normalized biomass of organisms in our study sites, although energy availability explained more of the variation in normalized biomass. The strong relationship between normalized biomass and delta15N suggested that energy availability contributed to primary structuring of size spectra, controlling the negative linear relationship of normalized biomass with size. Space availability had a weaker effect on normalized biomass, and may have contributed to secondary structuring of size spectra, controlling deviations from linearity in the normalized biomass-body size relationship.

description: Understanding how the dynamics of vegetation growth respond to climate change at different temporal and spatial scales is critical to projecting future ecosystem dynamics and the adaptation of ecosystems to global change. In this study, we investigated vegetated growth dynamics (annual productivity, seasonality and the minimum amount of vegetated cover) in China and their relations with climatic factors during 1982–2011, using the updated Global Inventory Modeling and Mapping Studies (GIMMS) third generation global satellite Advanced Very High Resolution Radiometer (AVHRR) Normalized Difference Vegetation Index (NDVI) dataset and climate data acquired from the National Centers for Environmental Prediction (NCEP). Major findings are as follows: (1) annual mean NDVI over China significantly increased by about 0.0006 per year from 1982 to 2011; (2) of the vegetated area in China, over 33% experienced a significant positive trend in vegetation growth, mostly located in central and southern China; about 21% experienced a significant positive trend in growth seasonality, most of which occurred in northern China (>35°N); (3) changes in vegetation growth dynamics were significantly correlated with air temperature and precipitation (p < 0.001) at a region scale; (4) at the country scale, changes in NDVI was significantly and positively correlated with annual air temperature (r = 0.52, p < 0.01) and not associated with annual precipitation (p > 0.1); (5) of the vegetated area, about 24% showed significant correlations between annual mean NDVI and air temperature (93% positive and remainder negative), and 12% showed significant correlations of annual mean NDVI with annual precipitation (65% positive and 35% negative). The spatiotemporal variations in vegetation growth dynamics were controlled primarily by temperature and secondly by precipitation. Vegetation growth was also affected by human activities; and (6) monthly NDVI was significantly correlated with the preceding month’s temperature and precipitation in western, central and northern China. The effects of a climate lag of more than two months in southern China may be caused mainly by the abundance of precipitation. These findings suggest that continuing efforts to monitor vegetation changes (in situ and satellite observations) over time and at broad scales are greatly needed, and are critical for the management of ecosystems and adapting to global climatic changes. It is likewise difficult to predict well future vegetation growth without linking these observations to mechanistic terrestrial ecosystem processes models that integrate all the satellite and in situ observations.
