description: Natural Killer (NK) cells, lymphocytes of the innate immune response, play a vital role in controlling infections and in tumor surveillance. NK cells provide protection by direct cytolysis of infected cells and by the production of pro-inflammatory cytokines such as, IFN-γ and TNF-α. Notably, NK cells have recently been identified to regulate the immune response by producing the anti-inflammatory cytokine IL-10. Several other cells can produce IL-10 during infections, however NK cell derived IL-10 can be critical in regulating immune response during early phases of infection and therefore protecting the host from excessive immunopathology. Although the regulatory role of NK cells seems to be plausible, the physiological relevance of NK cell mediated immune regulation during infections has not been demonstrated in detail. To investigate the immunoregulatory function of NK cells, I used Murine Cytomegalovirus (MCMV) infection induced by a high dose challenge and demonstrated that NK cells are a major IL-10 producer during acute stage of the infection. To elucidate the role of NK cell derived IL-10 during infections, I generated NK cell specific IL-10 knockout, NKp46iCre  Il-10flox/flox mice (NK-Il-10-/-) by crossing Il-10flox/flox mice with mice expressing Cre recombinase exclusively under the NK cell specific promoter, NKp46 (NKp46iCre knock-in mice). My results indicated that Cre mediated Il-10 genomic deletion occurred predominantly in NK cells but not in NKT, T and B cells. Enriched NK cells from NK-Il-10-/- mice failed to produce IL-10 upon ex vivo IL-2/IL-12 stimulation. Furthermore, histological analysis of the colon indicated that NK-Il-10-/- mice are free from aberrant inflammation. During sustained MCMV infection, significantly higher production of IFN-γ by CD8+ T cells of NK-Il-10-/- mice in salivary glands indicates that NK cell derived IL-10 contributes to the establishment of the immune suppressive environment in the organ. NK-Il-10-/- mice also demonstrated increased susceptibility to acute Listeria monocytogenes (LM) infection based on enhanced body weight loss. Taken together, I have successfully generated NK-Il-10-/- mice that lack the Il-10 gene exclusively in NK cells. The NK-Il-10-/- mouse can be used as an ideal model to dissect the immunoregulatory role of NK cells during various microbial infections and tumorogenesis.

description: Comment un auteur réécrit une histoire déjà publiée? De plus, quels moyens emploierait-il pour rendre justice à l’œuvre originale tout en y insérant sa part de créativité? Dans notre thèse en création littéraire nous avons tenté de répondre à quelques aspects de ces questions. La présente étude est divisée en trois parties. La première est une pièce de théâtre intitulée Persona, seras-tu… où nous utilisons le mythe d’Antigone comme point de départ mais avec une perspective contemporaine où Ismène, pour la première fois, tient la tête d’affiche. Nous avons aussi donné une grande place au chœur. Le deuxième chapitre est consacré à l’étude des Antigone modernes, soit celles de Cocteau, d’Anouilh et de Brecht, comparées à celle de Sophocle. Grâce en grande partie à une analyse textuelle, nous étudions comment ces auteurs ont réécrit les caractéristiques et l’évolution des personnages d’Ismène et du chœur. Finalement, le dernier chapitre est consacré à une réflexion sur notre démarche créative et à quel point les analyses du chapitre précédent nous ont aidée à construire notre chœur et notre Ismène.
Investigation of Structural and Magnetic Properties of First and Second Row Transition Metals with N,N’,N and S,N,S Pincer-type Ligands
Creators: name: Ouanounou, Sarah

Year: 2015

description: This work began with the ambition of probing the application of pincer ligands to control the geometry and bonding environments of metal centers by employing the bis(imino) pyridine ligand scaffold and an assortment of transition metals, particularly silver and a variety of paramagnetic centers. The work was further extended to the investigation of the SNS tridentate thiolate ligand backbone, specifically the bis(methylthiomethyl) pyridine and bis(ethylthiomethyl) pyridine ligand frameworks with a similary array of transition metal centres. Along with the reports of novel coordination compounds and analysis of trends in bonding, computational chemistry was utilized to correlate the data obtained experimentally with computed models. Synthesis, characterization and computational studies are presented herein. Chapter 1 presents a brief history of the bis(imino) pyridine ligand as well as its synthesis and characterization. Chapter 2 presents a brief history of the S,N,S ligand as well as its synthesis and characterization. Chapter 3 presents the synthesis of a series of first row transition metal bromide-bis(imino) pyridine complexes along with their characterizations and an analysis of bonding trends. Chapter 4 presents the synthesis of a series of first row transition metal bromide-S,N,S ligand complexes along with their characterizations and an analysis of bonding trends. Chapter 5 presents a general conclusion to the work.

description: The trend towards the automation and robotization of warfare, enabling the exercise of violence from a distance, has been long-present, dating back to such inventions as the bow and arrow that allowed an archer to kill from afar. Today’s military drones now permit an extreme separation between rivals. James Der Derian’s concept of virtuous war encapsulates a certain normative view of current and future wars. A rationale of the actors waging virtuous war is that violence is used in a cleaner way, resulting in ever fewer battle deaths. In this thesis, I argue that the next step in the progression of military weaponry is the inclusion of artificial superintelligence (hereinafter ASI) in the American drone and counterterrorism program. While including this technology into the American war machine may represent a moral objective, I conclude that the use of ASI for military purposes is immoral because accountability becomes indeterminable.

Phosphor
Blaualgen

description: Increased external nutrient loads of anthropogenic origin, especially those of phosphorus (P), were one of the major causes of eutrophication during the first half of the twentieth century in Europe. They led to deterioration of lake ecosystems, particularly including noxious blooms of (potentially toxic) cyanobacteria. From the 1970-1980s, strategies to decrease the phosphorus loads from sewage were increasingly implemented, among them are the ban of phosphates in detergents, the expansion of sewer systems and improvement in wastewater treatment to remove nutrients. Case studies of eight lakes, whose response to point source reduction of phosphorus was observed over decades, show that a pronounced reduction of the phosphorus load from point sources can be achieved either by the diversion of inflows carrying high loads, by upgraded sewage treatment, or by phosphorus precipitation in the major tributary directly before its inflow into the water body. Outcomes demonstrate that in order to effectively control cyanobacterial blooms, the measures taken need to reduce in-lake concentrations of total phosphorus below 20-50 Ţg L-1, with this threshold varying somewhat between lakes depending in particular on hydromorphological and biological conditions. Whether and when load reduction succeeds in controlling cyanobacteria depends primarily on the load remaining after remediation and on the water residence time.

description: The extent of ribosomal heterogeneity has caught increasing interest over the past few years, as recent studies have highlighted the presence of structural variations of the ribosome. More precisely, the heterogeneity of the ribosome covers multiple scales, including the dynamical aspects of ribosomal motion at the single particle level, specialization at the cellular and subcellular scale, or evolutionary differences across species. Upon solving the ribosome atomic structure at medium to high resolution, cryogenic electron microscopy (cryo-EM) has enabled investigating all these forms of heterogeneity. In this review, we present some recent advances in quantifying ribosome heterogeneity, with a focus on the conformational and evolutionary variations of the ribosome and their functional implications. These efforts highlight the need for new computational methods and comparative tools, to comprehensively model the continuous conformational transition pathways of the ribosome, as well as its evolution. While developing these methods presents some important challenges, it also provides an opportunity to extend our interpretation and usage of cryo-EM data, which would more generally benefit the study of molecular dynamics and evolution of proteins and other complexes.
Newspoll and the new reality of post-election polling

description: After the 2010 election, with its drawn-out count and those interminable crossbench negotiations, opposition leader Tony Abbott pointed out that for the first time in living memory the victor, Labor, hadn't enjoyed an immediate opinion poll boost. But then came 7 September 2013, the contest that elevated him to prime minister, and for a second time there was no bounce. The earliest post-election polls, from Essential and Morgan, put the Abbott government's support at the same or a slightly lower level than at the ballot box (although the first post-election Newspoll, seven weeks after the vote, did register a temporary jump in Coalition support). And now 2016 has made it three out of three, with today's Newspoll registering 50-50 two-party-preferred support, compared to 50.4-49.6 in the government's favour at the 2 July election. Federal election results in this country usually follow a certain pattern (or at least they did before the global financial crisis ushered in a stubbornly sluggish economic environment). Not only was the victor's campaign pronounced superior, but the outcome itself was judged the 'correct' one by a greater proportion of voters than had actually given it their support on the day. Polls showed increased support for the government - and, indeed, when asked which party they had voted for, more would claim to have chosen the victor than actually had. But not these last three elections.
Design of a Fast Location-Based Handoff Scheme for Vehicular Networks

IEEE 802.11

description: IEEE 802.11 is an economical and efficient standard that has been applied to vehicular networks. However, the long handoff latency of the standard handoff scheme for IEEE 802.11 has become an important issue for seamless roaming in vehicular environments, as more handoffs may be triggered due to the higher mobility of vehicles. This thesis presents a new and fast location-based handoff scheme particularly designed for vehicular environments. With the position and movement direction of a vehicle and the locations of the surrounding APs, our protocol is able to accurately predict several possible APs that the vehicle may visit in the future and to assign these APs different priority levels. APs on higher priority levels will be first scanned. Once a response to scanning from an AP is received, the scanning process ends immediately. A blacklist scheme is also used to exclude those APs that showed no response to the scanning during previous handoffs. Thus, time spent on scanning APs is supposed to be significantly reduced. The simulation results show that the proposed scheme attains not only a lower prediction error rate, but also a lower MAC layer handoff latency, and that it has a smaller influence on jitter and throughput; moreover, these results show that the proposed scheme has a smaller total number of handoffs than other handoff schemes.
Towards an Enhanced Understanding of Dance Education and the Creative Experience

description: The purpose of this study was to understand the significance of emotions and the body in the lived creative experience in dance. Using a phenomenological approach, I was interested in gaining a deepened understanding of the creative experiences of members of Canada’s contemporary dance community. Currently, dance is taught in multiple contexts of education including K-12 arts education and physical education, recreational studios, university settings such as in faculties of education, kinesiology, and fine arts, and in conservatory-style pre-professional training programs. As a result, there appears to be little evidence of a holistic pedagogical approach. Coming from a predominantly ballet-oriented dance training background, I wanted to learn what it’s like to create dance; specifically how contemporary dancers use their bodies and emotions as part of their creative process. I had the pleasure of being an invited guest, writer, speaker, and researcher at the 2008 Canada Dance Festival (CDF), a biennial dance festival that takes place in Ottawa, Ontario, Canada. Results shed light on rarely discussed facets of the creative experience in dance. This study explores the way dancers optimally want to feel, how they prepare to feel the way they want to feel, what obstacles they encounter, and what strategies allow them to revisit their optimal feel within their creative experience in dance. Doing so, the role of the body and the emotions in dance are better understood. A description of the 2008 Canada Dance Festival as a transactional space also surfaced. There, the CDF is understood as a place where the art of dance’s perceived meaning and values are discussed, and ultimately negotiated. Finally, results also contributed to an enriched understanding of artistic identity in dance as an ongoing process of becoming. With an enhanced pedagogical understanding of dance education, a final discussion unearths implications of this work and shines a spotlight on future research in dance scholarship.
Biodegradation of winery biomass wastes by developing a symbiotic multi-fungal consortium

description: Australia is sixth largest global wine grape producer with an annual production of 1.75 million metric tonnes (2012-13). Due to poor digestibility and minor phenolic toxicity, winery biomass waste has limited use as either animal feed or compost fertilizer. Fungi are considered as efficient biomass degraders. The results of this PhD study showed that simple pre-treatment process such as autoclaving, combined with mixed fungal consortium application and metabolomics, generated substantial biomass degradation. This degradation generated numerous metabolites such as sugars, alcohols and fatty acids which can be applied to generate biofuel molecules such as bioethanol and medicinally important metabolites.
A Possible Role for Salicylic Acid-induced Genes in Fusarium Graminearum Infection
Creators: name: Alharthi, Reem
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2015

description: The ability of Fusarium graminearum to metabolize the plant hormone salicylic acid (SA) and use it as a carbon source was investigated in previous studies in our laboratory. The expression of some F. graminearum genes was upregulated in presence of SA. However, the role of those induced genes in SA degradation was not investigated. This study aimed at characterizing six candidate genes predicted to encode enzymes with ability to catalyze one of the first two-enzymatic steps in SA degradation by F. graminearum. Those genes are FGSG_09063, FGSG03657, FGSG_09061, FGSG_03667, FGSG08358 and FGSG_08037. In order to investigate the function of those genes, genes were individually inactivated by gene replacement and the deletion mutant strains were tested for their ability to grow in solid and liquid medium supplemented with SA as the sole carbon source. Results indicated that FGSG_03667 is an essential gene in the SA degradation pathway. This gene is predicted to encode a hydroxyquinol 1,2 dioxygenase, an enzyme that catalyzes the conversion of hydroxyquinol to 3-hydroxy-cis,cis-munocate. In addition, results indicated that two other genes, FGSG_03657 and FGSG_09061, contribute to the initial degradation of SA in culture. Those genes are predicted to encode a salicylate 1-monooxygenase and a 2,3 dihydroxybenzoic acid decarboxylase, respectively. Those two enzymes can catalyze the conversion of SA to catechol. Taken all together, the results of this study suggest that catechol is the first catabolic intermediate in the degradation of SA in F. graminearum, and that FGSG_03667 is a gene encoding a wide range substrate enzyme that can use catechol. Further studies need to be done to support this interpretation from the biochemistry perspective.

description: Venture capital finances high-risk, high-return projects. In addition to financing, venture capitalists provide advice and expertise in management, commercialization, and development that enhance the value, success, and marketability of projects. Venture capitalists also have skills in selecting projects with potentially high returns. The first chapter investigates the contracting relationship between venture capitalists and entrepreneurs in a setting where the venture capitalist and entrepreneur contribute intangible assets (advice and effort) to a project that are non-contractible and non-verifiable. In general, in the private market equilibrium, advice provided by the venture capitalist and the number of projects funded are lower than the social optimum. Government tax and investment policies may alleviate these market failures. The impact of a capital gains tax, a tax on entrepreneur’s revenue, an investment subsidy to venture capitalists, and government run project enhancing programs are evaluated. Finally, we analyze the effects of a government venture capital firm competing with private venture capital. The second chapter focuses on competition in venture capital markets. We model a three-stage game of fund raising, investment in innovative projects and input of advice and effort, where fund raising is used as an entry deterrence mechanism. We examine the impacts of taxes and subsidies on venture capital market structure. We find that a tax on venture capitalist revenue and a tax on entrepreneur revenue increase the likelihood of entry deterrence and reduce the number of projects funded in equilibrium. A subsidy on investment reduces the likelihood of entry deterrence and increases the number of projects funded. The third chapter examines the venture capitalist's choice of investment in project selection skills and investment in managerial advice. We model, separately, a private venture capitalist and a labour-sponsored venture capitalist (LSVCC) with different objectives. A LSVCC is a special type of venture capitalist fund that is sponsored by a labour union. The private venture capitalist maximizes its expected profits, while the LSVCC maximizes a weighted function of expected profits and returns to labour. Consistent with empirical evidence, the quality of projects, determined by project selection skills and managerial advice, is higher for the private venture capitalist.

description: This study was conducted to investigate the urban geochemistry of the city of Windsor (Ontario) and to provide added source apportionment information to work being carried out by the Canadian government. The goal of this study was to investigate the distribution, spatial variation and sources of manganese in urban Windsor soil. The literature indicates that human exposure to high levels of manganese, via inhalation, can cause respiratory and/or neurological effects. At the outset of the present study it was first hypothesized that vehicular traffic was the dominant source of anthropogenic manganese. An alternative hypothesis was that there were multiple anthropogenic sources of manganese in Windsor. The sample collection scheme was designed to determine (1) the current and background soil concentrations of manganese in Windsor, (2) the spatial distribution of manganese in order to reveal sources of manganese, and (3) the manganese content of moss-sequestered airborne particles, which can potentially deposit onto the soil surface, using low-technology biomonitoring. The first phase of the study consisted of a preliminary soil survey which identified elevated areas of soil manganese concentrations. During this survey, the field efficiency of a field portable X-ray fluorescence (FPXRF) instrument, as well as sample preparation methods were evaluated. Efficiency of the FPXRF was determined by comparison to ICP-MS, a traditional trace element analysis method. The preliminary soil survey identified several areas of elevated (ranging from 884 to 2390 ppm) soil manganese which were further investigated during the second, more complete, soil survey. The moss biomonitoring technique of using moss bags was used to collect airborne particles for semi-quantitative analysis. Analysis of soil samples included total manganese and other trace elements, pH, moisture and carbon content, and manganese speciation. Urban Windsor soil manganese distribution revealed both natural and anthropogenic sources of soil manganese and three distinct soil sample types, transect, baseline and natural. In general, manganese in Windsor had a west-to-east trend of decreasing levels in soil and moss-sequestered airborne particles. The latter showed a modern-day elemental signature while the former (collocated soil) a legacy elemental signature. It was concluded that both the FPXRF instrument and the moss biomonitoring technique can be useful screening tools in studies of urban environments.

Beyond the Boundaries of SMOTE: A Framework for Manifold-based Synthetic Oversampling

description: Within machine learning, the problem of class imbalance refers to the scenario in which one or more classes is significantly outnumbered by the others. In the most extreme case, the minority class is not only significantly outnumbered by the majority class, but it also considered to be rare, or absolutely imbalanced. Class imbalance appears in a wide variety of important domains, ranging from oil spill and fraud detection, to text classification and medical diagnosis. Given this, it has been deemed as one of the ten most important research areas in data mining, and for more than a decade now the machine learning community has been coming together in an attempt to unequivocally solve the problem. The fundamental challenge in the induction of a classifier from imbalanced training data is in managing the prediction bias. The current state-of-the-art methods deal with this by readjusting misclassification costs or by applying resampling methods. In cases of absolute imbalance, these methods are insufficient; rather, it has been observed that we need more training examples. The nature of class imbalance, however, dictates that additional examples cannot be acquired, and thus, synthetic oversampling becomes the natural choice. We recognize the importance of selecting algorithms with assumptions and biases that are appropriate for the properties of the target data, and argue that this is of absolute importance when it comes to developing synthetic oversampling methods because a large generative leap must be made from a relatively small training set. In particular, our research into gamma-ray spectral classification has demonstrated the benefits of incorporating prior knowledge of conformance to the manifold assumption into the synthetic oversampling algorithms. We empirically demonstrate the negative impact of the manifold property on the state-of-the-art methods, and propose a framework for manifold-based synthetic oversampling. We algorithmically present the generic form of the framework and demonstrate formalizations of it with PCA and the denoising autoencoder. Through use of the helix and swiss roll datasets, which are standards in the manifold learning community, we visualize and qualitatively analyze the benefits of our proposed framework. Moreover, we unequivocally show the framework to be superior on three real-world gamma-ray spectral datasets and on sixteen benchmark UCI datasets in general. Specifically, our results demonstrate that the framework for manifold-based synthetic oversampling produces higher area under the ROC results than the current state-of-the-art and degrades less on data that conforms to the manifold assumption.

description: The basidiomycete Ustilago hordei causes covered smut disease of barley and oats. Virulence effectors promoting infection and supporting pathogen lifestyle have been described for this fungus. Genetically, six avirulence genes are known and one codes for UhAVR1, the only proven avirulence effector identified in smuts to date that triggers complete immunity in barley cultivars carrying resistance gene Ruh1. A prerequisite for resistance breeding is understanding the host targets and molecular function of UhAVR1. Analysis of this effector upon natural infection of barley coleoptiles using teliospores showed that UhAVR1 is expressed during the early stages of fungal infection where it leads to HR triggering in resistant cultivars or performs its virulence function in susceptible cultivars. Fungal secretion of UhAVR1 is directed by its signal peptide and occurs via the BrefeldinA-sensitive ER–Golgi pathway in cell culture away from its host. Transient in planta expression of UhAVR1 in barley and a nonhost, Nicotiana benthamiana, supports a cytosolic localization. Delivery of UhAVR1 via foxtail mosaic virus or Pseudomonas species in both barley and N. benthamiana reveals a role in suppressing components common to both plant systems of Effector- and Pattern-Triggered Immunity, including necrosis triggered by Agrobacterium-delivered cell death inducers.

description: Per ottenere dei buoni risultati scolastici, gli allievi immigrati e, in generale, coloro che, per diversi motivi si possono considerare “vulnerabili” non devono solo potere esprimersi con buona fluenza nella lingua di scolarizzazione: devono dominare anche i diversi tipi di discorsi accademici specifici delle differenti materie del curricolo. Dato che il sapere è praticamente indissociabile della lingua che lo concretizza, il progetto “Lingue nell’educazione, lingue per l’educazione” difende l’idea che tutti gli insegnanti devono essere insegnanti di lingua, in quanto conoscono ciò che dal punto di vista linguistico viene richiesto dalla loro disciplina e le strategie più adeguate al sostegno linguistico dei loro studenti. Questo studio propone alcune soluzioni possibili.  Language(s) of Schooling: Focusing on vulnerable learners In order to achieve educational success pupils from migrant backgrounds must be more than conversationally fluent in the language of schooling: they must also master the varieties of academic language that constitute the fabric of the different curriculum subjects. Because knowledge is virtually inseparable from the language that embodies it, the project “Languages in Education – Languages for Education” takes the view that all teachers must be language teachers in the sense that they are aware of the specific language demands of their subject(s). This study suggests some of the ways in which this challenge can be met.

These limitations are: lack of a well defined read zone, interference, and environment sensitivity. To overcome these limitations a novel receiver device is introduced into the system. The use of such device or devices mitigates the issues by enabling more "anchor points" in the system. Two such devices exist in industry and academia: the Astraion Sensatag and the Gen2 Listener. The drawbacks of the Sensatag is that it offers poor performance in capturing tag signals. The Gen2 Listener is based on the expensive software defined radio hardware. The purpose of the thesis was to develop a receiver that will enable several new RFID applications that are not available with current RFID systems. The receiver, named ARR (Augmented RFID Receiver), receives tag and reader signals, which are decoded by an FPGA and the results are reported through Ethernet. This device is central to the augmented RFID system. To show the suitability of such an approach, the performance of the implementation was compared to the other two outlined solutions. A comparison of the read rate and range of the implementations were the defining factors. The analysis showed that the ARR is capable of receiving tag signals with a read rate of 50% for passive and 66% for semi-passive tags at a one meter distance and is capable of receiving tag signals at a maximum of 3.25 meters for passive and 5.5 meters for semi- passive tags, with the reader being within 8 meters of the ARR. Two applications were implemented to showcase the ARR: an RFID portal and protocol analyzer.

description: En Bolivie, l’arrivée au pouvoir du Mouvement vers le Socialisme (MAS) en 2005 a conduit à l’adoption par l’État de politiques agraires novatrices en matière d’égalité des genres. S’inspirant de la théorie de la redistribution et de la reconnaissance de Fraser (1995), cette thèse avance que les politiques agraires du MAS ne favorisent pas nécessairement les paysannes les plus pauvres. Si le gouvernement Morales a réalisé des progrès considérables en ce qui concerne le droit à la terre et la participation des femmes dans les organisations paysannes, ces progrès sont limités par l’inefficacité des mesures s’attaquant aux inégalités socio-économiques mises en place par le MAS. Dans les terres-territoires de l’Altiplano Sud bolivien, plusieurs femmes se trouvent par exemple dans une position ambigüe par rapport à la revendication de titres fonciers individuels.

description: L’habitat préférentiel, la distribution et la reproduction du fouille-roche gris (Percina copelandi), une espèce de percidés menacée d’extinction au Canada, ont été examinés dans quatre tributaires de la rivière des Outaouais (rivières Blanche [Gatineau], Blanche [Thurso], Petite-Nation et Saumon, Québec) sur un cycle quasi annuel (printemps, été, automne). Il s’agit de la première étude de cette espèce qui combine des données d’utilisation préférentielle d’habitat dans plusieurs tributaires en tenant compte des variations saisonnières. Cette étude a permis de relever que 1) l’espèce semble préférer des habitats moins spécifiques que ne l’indiquent les études passées et 2) les barrières naturelles ainsi que les fosses en aval des rapides sont importantes pour expliquer la répartition de l’espèce dans les quatre rivières. Les résultats de cette étude aideront les équipes nationale et québécoise de rétablissement de l’espèce à prendre des décisions éclairées pour la sauvegarde cette espèce en péril.

description: Mathematical models provide unique insights to real-world problems. Within the context of infectious diseases, models are used to explore the dynamics of infections and control mechanisms. Human papillomavirus (HPV) globally infects about 630 million people, many of these infections develop into cancers and genital warts. Vaccines are available to protect against the most prevalent and devastating strains of HPV. The introduction of this vaccine as part of a national immunization program in Canada is a complex decision for policy-makers in which mathematical models can play a key role. We use the current recommendations provided by the World Health Organization to explore the integral role mathematical models have in the decision to incorporate the HPV vaccine within a national immunization program. We then provide a review of the literature discussing the role of mathematical models in the decision to include a vaccine in a national immunization program within the context of the HPV vaccine. Next, we evaluate the current standing of mathematical models used within the context of HPV immunization, to highlight the types of models used, underlying assumptions and general recommendations made about these immunization programs. Then, we create and analyze a model to explore the possibility of bettering the current HPV vaccine strategy in Canada. We focus on the effects of the grade of vaccination and the number of doses required to eradicate the targeted strains of HPV.

description: As part of the ongoing world-wide effort in improving time and frequency references, a high accuracy optical frequency standard was developed using the electric quadrupole allowed clock transition at 445 THz (674 nm) in a trapped and laser cooled 88Sr+ion. An ion trap system of the endcap design has been recently evaluated with a fractional frequency uncertainty which surpasses the accuracy of the current realization of the SI second. This thesis seeks to further evaluate the limiting systematic shifts of the device by optimizing a second ion trap reference based on a rf Paul trap design, which was then compared with the endcap trap reference frequency. The comparison of the two ion traps' reference frequencies confirmed an overall offset of -0.36 pm 0.08 Hz at the 445 THz reference frequency corresponding to a fractional frequency offset of 8 x 10^-16.

description: This research examines the revolution of 2010 in Tunisia due to the paucity of empirical research on the subject and to resolve analytical problems that plague research on similar events. The research is based in both the cultural turn in social movement research and the state constructionist theory of revolutions. The methodology employed is a case study which combines a content analysis of an Al Jazeera news program called Al Hassad Al Maghrebi with data from two public opinion surveys conducted in Tunisia shortly after the revolution, and pre-existing academic research. The findings indicate that Al Jazeera did play a role in increasing mobilization against the Ben Ali regime by broadcasting the spread of protests and regime concessions. This was facilitated by the censorship practices of the Ben Ali regime which caused a popular news channel like Al Jazeera to rely purely on opposition sources for its broadcasts.
US election: what impact do celebrity endorsements really have?

description: Celebrities are always part of the show in the US presidential election. This is by no means a new trend. Historians have traced the role of celebrities in politics back to the 1920 election, when Warren Harding was endorsed by film stars including Lillian Russell. In 1960, John F. Kennedy was endorsed by Rat Pack members Sammy Davis junior and Dean Martin. More recently, Oprah Winfrey, George Clooney, will.i.am, Brad Pitt and Samuel L. Jackson supported Barack Obama. Actor Clint Eastwood, however, endorsed Republicans John McCain in 2008 and Donald Trump this time around. The 2016 election is no different. So how much of a difference, if any, do high-profile endorsements make? And to which demographics?

description: This work is a first attempt at classification of Lexical Aspect. In this dissertation I describe eight lexical aspectual classes, each initially containing a few members. Using distributional analysis I generate 132 additional seeds, each of which was approved by at least seven out of nine judges. These seeds are in turn fed into a supervised machine learning system, trained on 136 lexical and syntactic features. I experiment on one 8-way classification task, one 3-way classification task, and ten binary classification tasks, and show that five of the eight classes are identified better than by a random baseline measure by a statistically significant margin. Finally, I analyze the relative contribution of each of four feature groups and conclude that the same features which are best in identifying phrasal aspect are also most informative for lexical aspect.

description: The European Soil Strategy for 2030 by the European Commission has set the foundations for an overarching approach to the protection of soils in Europe. In this scientific opinion paper, the German Environment Agency (âĄ UBAâĄ ) lays down its key recommendations for the upcoming Soil Health Law. Feedback on legislative options is provided and experience gained in Germany in the past years on soil protection and restoration is shared. Knowing the outstanding importance of soils for human and ecosystem health, UBA strongly agrees that a new binding European legislative framework on soils with high ambition is urgently needed.
