description: The new method for aerosol measurement using wide-field stellar photometry was originally developed for B-filter data. The dependence of VAOD (vertical aerosol optical depth) on wavelength can be used to understand the physical characteristics of aerosol. The method has been extended for V and R filters using the Gaia stellar photometric catalog as the reference. We calculated the coefficients of the equation describing molecular and aerosol extinction of the atmosphere. For data in a particular filter, they depend on the telescope's location. Light towards shorter wavelengths has higher extinction. The VAOD, calculated in B, V, and R filters does not show monotonous dependence on wavelength, and there is increased dependence on the photometric methods for V and R filters. We studied the possible reasons for this unexpected behavior.

description: This study seeks to investigate the concept of using large waste rocks from mining operations as waste-heat thermal energy storage for remote arctic communities, both commercial and residential. It holds its novelty in analyzing such systems with an experimentally validated transient three-dimensional computational fluid dynamics and heat transfer model that accounts for interphase energy balance using a local thermal non-equilibrium approach. The system performance is evaluated for a wide range of distinct parameters, such as porosity between 0.2 and 0.5, fluid velocity from 0.01 to 0.07 m/s, and the aspect ratio of the bed between 1 and 1.35. It is demonstrated that the mass flow rate of the heat transfer fluid does not expressively impact the total energy storage capacity of the rock mass, but it does significantly affect the charge/discharge times. Finally, it is shown that porosity has the greatest impact on both fluid flow and heat transfer. The evaluations show that about 540 GJ can be stored on the bed with a porosity of 0.2, and about 350 GJ on the one with 0.35, while the intermediate porosity leads to a total of 450 GJ. Additionally, thermal capacity is deemed to be the most important thermophysical factor in thermal energy storage performance.

description: This thesis presents four distinct studies of psychological and social integration of homeless and vulnerably housed individuals. The first study presents a predictive model of psychological integration, defined as a sense of belonging and membership to one’s community. The second study presents a predictive model of social integration, defined as how an individual engages with others in the community. The third study presents a mixed methods comparative analysis of homeless and vulnerably housed individuals with “high” and “low” levels of psychological and social integration. The fourth study presents a reflexive analysis of conducting interviews with homeless and vulnerably housed individuals. Data for this research comes from a two-year longitudinal study conducted in Ottawa, Ontario. Participants were men and women, over the age of 18 (Baseline: N = 397; Follow-up 1: N = 341; Follow-up 2: N = 320) who were either homeless or vulnerably housed at the study’s outset. Quantitative data analyses occurred at Follow-up 1 and 2 and utilized hierarchical multiple regression. Qualitative data analyses used a general inductive approach utilizing a First Cycle and Second Cycle coding method (Saldana, 2009). Social support was a significant predictor of both psychological integration and social integration. Individuals with high levels of social support had high levels of psychological and social integration. Social support proved to be the only predictor to be significantly associated with social integration at both Follow-up 1 and 2. Psychological integration was positively associated with several variables at Follow-up 1 and 2: increased age, living in high quality housing, and residing in a neighbourhood that is perceived as having a positive impact. The mixed methods analysis uncovered several salient themes that affected psychological and social integration, including substance use in one’s housing and neighbourhood, neighbourhood safety and location, and housing quality. The reflexive component of the thesis highlighted the importance of location when conducting interviews and the power dynamics of the interview process. The results are discussed in terms of implications for service delivery and policy.

description: Магический реализм, зародившийся как художественный метод в середине XX века, продолжает оставаться одним из наиболее значимых явлений в мировой литературе. Его уникальность заключается в способности соединять реальное и иррациональное, создавая нарративы, которые раскрывают не только внешние события, но и глубинные слои человеческого сознания. В условиях современности, характеризующейся глобальными кризисами, цифровой трансформацией и фрагментацией идентичности, магический реализм приобретает новое звучание, становясь инструментом для визуализации внутреннего мира личности.

description: This thesis challenges common assumptions of trans moving images by applying theories of identification to an autoethnographic close reading of three specific texts – Hedwig and The Angry Inch (John Cameron Mitchell, 2001), Dallas Buyers Club (Jean- Marc Vallée, 2013) and Transparent (Jill Soloway, 2014) - considered by both mainstream and queer audiences to feature transgender characters and experiences. This thesis, while limited to the author’s experience as a trans woman, attempts to advance the argument that identification with trans moving images may change with one’s transition and require a reassessing of “what is trans” along with resituating the trans spectator from “object of the gaze” to “bearer of the look” (Mulvey, 1975).

description: This work focused on the development of starch-based (potato, corn, sweet potato, green bean and tapioca) edible packaging film incorporated with blueberry pomace powder (BPP). The optical, mechanical, thermal, and physicochemical properties were subsequently tested. The film color was not affected by the addition of BPP. BPP incorporated into corn and green bean starch films showed increased light barrier properties, indicating a beneficial effect to prevent UV radiation-induced food deterioration. Film thickness and transparency were not primarily affected by changing the starch type or the BPP concentration, although the corn starch films were the most transparent. Furthermore, all films maintained structural integrity and had a high tensile strength. The water vapor transmission rate of all the films was found to be greater than conventional polyethylene films. The average solubility of all the films made from different starch types was between 24 and 37%, which indicates the usability of these films for packaging, specifically for low to intermediate moisture foods. There were no statistical differences in Differential Scanning Calorimetry parameters with changes in the starch type and pomace levels. Migration assays showed a greater release of the active compounds from BPP into acetic acid medium (aqueous food simulant) than ethanol medium (fatty food simulant). The incorporation of BPP into starch-chitosan films resulted in the improvement of film performance, thereby suggesting the potential for applying BPP into starch-based films for active packaging.
Assessing the impact of Board of Directors on corporate entrepreneurship of large public companies

Publisher: name: Swinburne
Year: 2024

description: While many researchers have proposed strategies for corporate entrepreneurship (CE) success, there is a lack of published research as to why CE succeeds or fails at large public companies. This paper explores one aspect of this issue, namely how a company's Board of Director's impacts its CE. Many academics have advocated CE as the driver of corporate innovation and growth including Covin and Slevin (1991), Zahra (1993), Lumpkin and Dess, 1996, and Birkinshaw (2003). The business community increasingly accepts the importance of CE. For example, Stewart (2006) reported the opinion of Jeff Immelt, the chairman and CEO of General Electric, that whereas the focus of his predecessor, Jack Welch, was acquisitions and improvements in productivity, in the future the market would reward organic growth driven by innovation. At the same time, the literature also identifies a number of large companies that have been unsuccessful in their CE efforts. For example, O'Reilly and Tushman (2004) identify Kodak and Boeing as examples of companies that have failed in their attempts to adapt to market changes. The literature appears to be silent as to why CE experiments are successful at some firms and unsuccessful at others. While many authors, including Pinchot (1985) and Hamel (2002), have identified conditions required for CE to be successful, their prescriptions appear to be insufficient to ensure a high probability of success. Research is needed to identify the factors that determine the success or failure of CE initiatives. The authors of this paper explore one potential factor, that is: 'How do the actions of a firm's Board of Directors impact its corporate entrepreneurship?”

description: There has been an increased interest in Romeʼs connections with the Far East over the course of the last 20 years. This has resulted in the publication of many articles and monographs about the Roman involvement in the Red Sea which was the key maritime region linking the Far East with the West. This thesis synthesizes the recent scholarship on the Red Sea trade in Late Antiquity by merging all of the most up to date information into a concise narrative. In order to accomplish this, three major sources of information have been analyzed. Firstly, the historical time frame of all of the major regions of the Red Sea including Egypt, Aksum, and Himyar have been laid out in a straight forward narrative. This offers the most pertinent background information for the development of Red Sea trade. Secondly, the most up to date archaeological evidence has been incorporated into a description of the ancient maritime trade infrastructure of the Red Sea and Indian Ocean. The archaeological evidence broadens our knowledge of the roads through the Eastern Desert of Egypt, the ports of the Red Sea, and the development of the Indian subcontinent more generally. Thirdly, this thesis builds on all of the historical as well as archaeological data and attempts to quantify the impact of Red Sea trade on the Late Antique Roman Empire both economically and culturally. This synthesis helps to elucidate the growing conception among Late Antique scholars that the Roman Empire was far more interconnected with its eastern neighbours. This further nuances the role which outside forces had on the evolution of the Late Antique world.
The Use of Songs in the ESL / EFL Classroom as a Means of Teaching Pronunciation: A Case Study of Chilean University Students

description: In this thesis, I set out to investigate whether the use of songs can help L2 speakers learn to better perceive and produce suprasegmental phenomena. Effective pronunciation skills are necessary for successful communication and as such can greatly impact one’s personal, social, and professional life. Studying the use of songs for teaching pronunciation is interesting because as a linguistically rich material, songs can enhance learning due to their positive affective, social, and cognitive influence in the L2 classroom. Using songs to teach pronunciation within a Communicative Language Teaching (CLT) framework constitutes a novel approach to an underexplored area of classroom research. In order to learn how using songs might help native Spanish speakers learn English suprasegmentals, I conducted a mixed methods exploratory short-term case study of Chilean university students studying English Language and Literature at the Universidad Católica de Chile. Using three groups: a control, songs, and no-songs group, the pre- to post-course progress was measured first with the two treatment groups combined and then with them separated. In this way we were able to measure the effectiveness of songs compared to other materials as well as to no intervention whatsoever. After two weeks of instruction, we found that using songs can significantly help in the production of the schwa when reading a text and of thought groups when speaking freely. Results obtained in listening tests were not statistically significant. However, closer examination of the performance of individual songs- group participants showed not only a greater than average progress in different suprasegmental areas in both listening and speaking, but also an appreciation of songs as an effective and enjoyable means of learning pronunciation. It would be advantageous for future research to explore the effects of teaching the pronunciation areas using the same methodology but for longer periods of time with delayed post-course testing to determine whether the effects are long-term. In addition, further exploration into the relationship between pronunciation perception and production could provide insight for the development of more effective teaching techniques.

description: As the number of total knee arthroplasty (TKA) procedures increases annually, the patient demographic is shifting to include younger patients with higher expectations for post-operative function. The aim of this study was to compare movement patterns during activities of daily living among TKA patients and a healthy, age-matched group using 3D motion analysis. Specifically, this analysis looked at walking on level and inclined surfaces, as well as sitting up and down from a chair. It was predicted that (1) TKA patients would exhibit reduced knee extension moments at the operated limb and increased adduction moments at the contralateral limb during gait, (2) walking downhill would result in greater differences between TKA and control groups, compared to level walking, and (3) TKA participants would have greater flexion angles, moments and power values at the hip, compared to controls, during the sit-stand tasks. Seventeen participants (age=62±6 years, BMI=30±3 kg/m2, time after surgery=11±5 months) were recruited from the Ottawa Hospital, having undergone unilateral TKA by the same surgeon. An age-matched control group was composed of 17 individuals (age=63±8 years, BMI=27±4 kg/m2) who were recruited from the local community. Three dimensional (3D) biomechanical assessment was conducted with all participants performing five trials of walking on level and inclined surfaces, stair ascent and descent as well as sit-stand tasks. Results from this study were focused on gait and sit-stand transitions, showing that TKA participants exhibited altered gait patterns on both walking surfaces, with significantly smaller knee flexion angles and moments, as well as reduced peak power at the knee. The TKA group also experienced reduced knee extension moments; however, this was only significant for downhill walking. Consistent with our hypothesis, downhill walking resulted in greater discrepancies between the groups compared to level walking. Contrary to our third hypothesis, TKA participants exhibited significantly smaller peak hip flexion angles and moments during the sit-stand task, along with reduced hip abduction angles and knee abduction moments. The reduced knee flexion kinematics and kinetics observed during gait tasks, combined with the differences in frontal plane mechanics observed during the sit-stand task suggest that altered loading patterns persist six to twelve months after surgery. This may be a result of continued pre-operative movement patterns as well as the surgery itself, and should be kept in mind when developing rehabilitation programs for this patient population.

description: Frequent subgraph mining is a useful method for extracting biologically relevant patterns from a set of graphs or a single large graph. Here, the graph represents all possible RNA structures and interactions. Patterns that are significantly more frequent in this graph over a random graph are extracted. We hypothesize that these patterns are most likely to represent a biological mechanisms. The graph representation used is a directed dual graph, extended to handle intermolecular interactions. The graph is sampled for subgraphs, which are labeled using a canonical labeling method and counted. The resulting patterns are compared to those created from a randomized dataset and scored. The algorithm was applied to the mitochondrial genome of the kinetoplastid species Trypanosoma brucei. This species has a unique RNA editing mechanism that has been well studied, making it a good model organism to test RiboFSM. The most significant patterns contain two stem-loops, indicative of gRNA, and represent interactions of these structures with target mRNA.

description: This thesis presents a practical approach to reduce the overall testing time in a spherical near-field (SNF) antenna measurement environment. The premise of this work is that the acquisition time is mostly dominated by the mechanical movement and the processing electronic. Moreover, it is assumed that the transformation time to go from the near-field domain to the far-field domain (NF-FF transform) is small compared to the acquisition time. Thus this operation can be done repeatedly while the acquisition is on-going without significantly affecting the overall test time. This situation allows to continuously evaluate the far-field (FF) of the antenna under test (AUT), so that certain decision functions based on the radiation pattern of the antenna can be monitored. Such decision functions are based on the antenna specification, such as the gain, the side lobe level, etc. We do not proceed with a complete scan of the measurement sphere but effectively allow the probe to follow a directed path under control of an acquisition rule, so that the sampled near-field (NF) datapoints constitute an acquisition map on the sphere. The acquisition can then be terminated based on decision function values, allowing the smallest amount of data needed to ensure accurate determination of the AUT performance measures.

description: The focus of this research is on identifying the determinants of local-level climate change adaptive capacity in Caribbean small island communities. A single case study approach was employed to assess retrospectively both internal and external factors that contributed to the adaptive capacity of Paget Farm, Saint Vincent and the Grenadines. The Caribbean region’s first solar-powered desalination plant was implemented in the community specifically as a climate change adaptation strategy and thus provides an ideal case for retrospective analysis. A series of semi-structured interviews with local residents and key stakeholders revealed a number of interacting social and institutional factors that contribute to community-based adaptive capacity. Further analysis of institutional factors was undertaken using Social Network Analysis, which enabled visualization and quantification of vertical and horizontal institutional integration of the networks formed during different phases of project implementation. The research extends scholarly understanding of the determinants that influence local-level climate change adaptive capacity and provides practical evidence that can assist small island communities to respond to a changing climate.

description: Ovarian clear cell carcinoma (OCCC) is a rare subtype of gynecological cancer for which well-characterized and authenticated model systems are scarce. We provide an extensive characterization of ‘105C’, a cell line generated from an adenocarcinoma of the clear cell histotype using targeted next-generation sequencing, cytogenetic microarrays, along with analyses of AKT/mTOR signaling. We report that that the 105C cell line is a bona fide OCCC cell line, carrying PIK3CA, PTEN, and ARID1A gene mutations, consistent with OCCC, yet maintain a stable genome as reflected by low copy number variation. Unlike KOC-7c, TOV-21G, and RMG-V OCCC lines also mutated for the above genes, the 105C cells do not carry mutations in mismatch repair genes. Importantly, we show that 105C cells exhibit greater resistance to mTOR inhibition and carboplatin treatment compared to 9 other OCCC cell lines in 3D spheroid cultures. This resistance may be attributed to 105C cells remaining dormant in suspension culture which surprisingly, contrasts with several other OCCC lines which continue to proliferate in long-term suspension culture. 105C cells survive xenotransplantation but do not proliferate and metastasize. Collectively, we show that the 105C OCCC cell line exhibits unique properties useful for the pre-clinical investigation of OCCC pathobiology.

description: Adult neurogenesis is a process that produces neurons in the adult brain and garners potential for the development of novel therapeutic interventions to combat neurodegenerative and other brain related diseases. With the hope of increasing neurogenesis, active investigations are defining the cellular and molecular mechanisms that regulate adult neural precursor cell (NPC) survival, and thus maintain neurogenesis. Recently, autophagy, an intracellular recycling pathway, has been implicated in regulating adult NPCs in embryonic knockout mice models. Whether autophagy has a similar effect within the adult and how autophagy regulates development of adult NPC remains unknown. Here, we investigate the role of Beclin1, a gene responsible for autophagy induction, in adult hippocampal NPC function in mice. Retroviral-mediated removal of Beclin1 from proliferating adult NPCs in vivo led to a reduction in the survival of adult-born neurons. In addition, Beclin1 was removed specifically from nestin-expressing adult neural stem- and progenitor-cells through the development of a Beclin1 nestin-inducible knockout mouse. Beclin1 nKO mice had a reduction in NPC proliferation and development, and overall fewer adult-generated neurons. Together, these findings reveal Beclin1 is required for adult hippocampal neurogenesis through regulating the proliferation and survival of the NPCs, in the absence of changing NPC fate.

description: Cable-stayed bridges are massive structures which rely on their structural elements such as deck girder, towers and stay-cables for their stability. The bridge stay-cables can be considered as the most flexible elements of the cable-stayed bridges, and thus their structural stability integrity is verified for several phenomena which might affect them. Wind and wind/rain induced vibrations for bridge stay-cables were comprehensively studied by researchers worldwide; however recent projects have identified a new type of cable vibrations caused by ice accretion formed around the cable circumference. The current research proposed two ice accretion profiles for inclined bridge cables and has experimentally investigated the wind-induced vibrations of the two models for the bridge stay-cables with ice accretion, under different vertical (inclination) and horizontal (yaw) angles, and for different wind speeds. Initially, three models of the bridge cable with 1.0 cm and 2.0 cm ice profile were tested in the wind tunnel of cross-section 61 cm × 90 cm, and a maximum wind speed of 30 m/s. In total 6 cases with 1.0 cm ice thickness and 3 cases with 2.0 cm ice thickness were investigated and the vertical and torsional oscillatory displacements were recorded for wind speeds from 1.5 m/s to 15 m/s at intervals of 1.5 m/s. The wind-induced vibrations were analyzed and were compared with the response reported for cables without ice and with the rain-induced response for stay-cables. Computational Fluid Dynamics (CFD) simulations were performed to observe the drag, lift and pressure coefficients around the surface of the accreted cable models yawed and inclined at α = 0°, β = 0° and α = 60°, β = 15° under the effect of 10 m/s and 15 m/s wind speed applied for both cases. A verification for galloping divergent instability was conducted based on the Den Hartog formulation and the vertical vibrations obtained from the wind tunnel experiment.

description: Background: Laboratory diagnostic testing service delivery and compliance with international standards for laboratory quality are directly influenced by laboratory workforce competency. Many hospital laboratories in constrained resource settings such as Cambodia struggle to cope with the training needs of laboratory professionals in an environment of competing healthcare development priorities. Resource-limited countries need an adaptable and effective approach to provide laboratory professionals with job-specific quality oversight training to ensure the accuracy, timeliness, and reliability of diagnostic services. Case presentation: Here, we describe the results of an in-service training and mentoring program conducted with the Cambodia Ministry of Health at 12 tertiary-level hospital laboratories to drive improvements in laboratory quality management systems toward ISO 15189 accreditation, which demonstrated significant progress between baseline and outcome audits in a concurrent study. This case study describes the program, and evaluates how the four primary activities, including actionable gap assessments and planning, centralized and in situ training curriculum, in-person mentoring, and remote tele-mentoring via video communication technologies, contributed towards quality improvement in the participating laboratories. We evaluated participant responses to Likert scale and free response questions from program and training evaluation surveys, and we used thematic analysis to develop a model of best practices within the program’s four primary activities to inform future training approaches. Of these activities, participants agreed most highly that in-person visits and planning based on gap assessments contributed to their learning and ability to improve laboratory operations. Tele-mentoring was rated lowest by participants, who were critical of excessive group dialogue and distraction during web-conferencing; however, feedback suggests both in-person and remote mentoring contribute to continuing education, accountability to action, and peer collaboration and problem solving to improve workforce efforts toward improved quality management systems. Conclusions: We recommend here a package of in-service training activities for laboratory quality management system improvement initiatives in resource constrained settings that includes needs-based curricula and personalized action plans for participants; interactive and on-site training workshops; and in-person mentoring, complemented with well managed and regular tele-mentoring that focuses on knowledge retention, accountability to goals, and collaborative problem solving. Our model presents an adaptable approach to human resource development for quality improvement in medical laboratories.

description: Social inequalities in health have been well documented in the literature. Despite the universal health care system and detailed measures of health surveillance, socioeconomic disparities related to cardiovascular diseases (CVD) remain present and are predicted to increase due to growing socioeconomic inequalities (Pampalon, 2008). Many health policy initiatives, such as the development of cardiac rehabilitation programs, were put in place in order to promote heart healthy lifestyles. These programs are provided as a medical and educational solution to prevent, manage, and lower risks of developing complications due to cardiovascular diseases, yet participation rates are as low as 37% for eligible individuals (Heart and Stroke Foundation of Canada, 2013). By drawing chiefly on Pierre Bourdieu’s sociocultural theory of practices, this qualitative study aims to understand the social variation of lifestyles in the context of cardiac rehabilitation of two groups of men from contrasting socioeconomic conditions. Sixty in-depth interviews were conducted with francophone men (mean age of 56.5) from the Outaouais region (Québec, Canada) who have suffered from a cardiac event requiring hospitalization. A number of studies on cardiovascular health have indicated health and lifestyle disparities among the male population. In order to provide a new perspective, this specific study drew principally on the notion of social capital in order to provide a more complete understanding of the social variation of lifestyles in the context of cardiac rehabilitation, particularly the impact these socioeconomic differences have on the quality of participants’ social capital, and how it shapes lifestyles after a heart intervention The results of this study are presented in an article which compares lifestyles and cardiac rehabilitation practices on the basis of three concepts of social capital, – social cohesion, trust, and social support. Results suggests that socioeconomic conditions influence levels of social cohesion, trust, and the quality of social support provided by social networks in the context of cardiac rehabilitation. Despite the underprivileged participant’s awareness of normative health lifestyles, they also were constrained by socio-cultural barriers, which limited a heart-healthy lifestyle.

description: The role of a roof on any building is to separate the interior environment of the building from the exterior environment, thereby making it a crucial component of the building design. Metal roof edges are the first line of defense against wind-induced loads on the roof system; however, data on the nature of these loads acting on the roof edge system is scarce. Previous studies with field measurements of wind pressure acting on the roof edge reported that metal flashings experienced negative pressure. These findings suggest that current building codes in North America (i.e. NBCC and ASCE codes) do not accurately identify wind design loads acting on roof edge systems. The Roof Edge Systems and Technologies (REST) project is a consortium of academia, government and roof industries, which was created to develop testing protocols and design guidelines for roof edges. The work presented in this thesis contributes to the collection and analysis of wind loads acting on metal roof edges, which were installed on the Canada Post building in Vancouver, Canada. The thesis presents the findings and analysis of the measured wind-induced pressure acting on all surfaces of three different edge configurations, namely the Anchor Clip Configuration (ACC), Continuous Cleat Configuration (CCC) and Discontinuous Cleat Configuration (DCC). The analysis showed the presence of negative pressure acting on all three faces of the configurations, in which the type of configuration had minimum effect on the magnitude and nature of the wind-induced loads. Furthermore, the top face of the edge configurations was found to experience the highest suction, and the front face of the edge coping was subjected to a net outward suction force due to the combination of the suction experienced by the coping front face and the positive pressure acting on the cleat. Comparison of these results with current NBCC and ASCE building codes highlight a need to update these codes in order to adequately design metal roof edges against wind action.

description: The objective of the present thesis research is to apply state-of-the-art experimental and data analysis techniques to the study of gas-liquid pipe flows, with a focus on conditions occurring in header-feeder systems of nuclear reactors under different accident scenarios. Novel experimental techniques have been proposed for the identification of the flow regime and measurement of the flow rates of both phases in gas-liquid flows. These techniques were automated, non-intrusive and economical, which ensured that their use would be feasible in industrial as well as laboratory settings. Measurements of differential pressure and the gas and liquid flow rates were collected in vertical upwards air-water flow at near-atmospheric pressure. It was demonstrated that the probability density function of the normalized differential pressure was indicative of the flow regime and using non-linear dimensionality reduction (the Elastic Maps Algorithm), it was possible to automate the process of identifying the flow regime from the differential pressure signal. The relationship between the probability density function and the power spectral density of normalized differential pressure with the gas and liquid flow rates in air-water pipe flow was also established and a machine learning algorithm (using Independent Component Analysis and Artificial Neural Networks) was proposed for the estimation of the phase flow rates from these properties. The proposed methods were adapted for use with single and dual conductivity wire-mesh sensors in vertical upwards and downwards air--water flows. A thorough evaluation of the performance and measurement uncertainty of wire-mesh sensors in gas-liquid flows was also performed. Lastly, measurements of the flow distribution in feeder tubes supplied with air-water mixtures by a simplified header model were collected and correlated to the observed flow patterns in the header.
La relation au divin chez Racine et Claudel

description: Cette thèse examine le dialogue avec le divin mis en scène dans le théâtre de Jean Racine et dans la Trilogie des Coûfontaine de Paul Claudel. Bien qu’éloignés tant par l’époque que par l’esthétique dramaturgique, ces deux auteurs donnent au divin une place importante dans leur théâtre, et en cela peuvent être rapprochés. La représentation du divin qu’on retrouve dans les tragédies profanes et religieuses de Racine éclaire celle, beaucoup plus complexe, du théâtre claudélien. Nous étudions d’abord les transformations que subit le visage du divin dans la dramaturgie racinienne, passant des traits flous et énigmatiques des tragédies profanes à ceux plus précis, parce que plus humains, des tragédies religieuses, en nous concentrant plus particulièrement sur la relation que les personnages entretiennent avec lui et sur les modifications de l’espace et du temps que cause son apparition sur la scène de théâtre. Le rapport au divin présent dans les drames de Claudel est ensuite analysé à la lumière des conclusions tirées de l’étude des tragédies raciniennes.

subject: Educational Methods

description: This masters project documents the process of the development of a game to teach nutritional behaviors as a strategy to address major health problems in the Hispanic populations in New England. The game can be easily adapted to meet diverse cultural requirements across the U.S. After discussing the major issues that plague nutrition education programs for Hispanic populations, this paper discusses arguments that support the idea to attempt to teach nutritional issues through the use of games. The paper also discusses the use of culturally appropriate nutrition symbols, the choice of quiz questions, as well as the research process that led to the current game product. A copy of the game board, as well as the user instructions are included in the Appendix.
Gestures towards the digital maypole

description: To paraphrase Blanchot: We are not learned; we are not ignorant. We have known joys. That is saying too little: We are alive, and this life gives us the greatest pleasure. The intensities afforded by mobile communication can be thought of as an extension of the styles and gestures already materialised by multiple maypole cultures, pre-digital community forms and the very clustered natures of speech and being. In his Critique of Judgment, Kant argues that the information selection process at the heart of communication is one of the fundamental activities of any aesthetically produced knowledge form. From this radial point, 'Gestures towards the digital maypole' begins the process of reorganising conceptions of modalities of communication around the absent centre and the affective realms that form through the movement of information-energy, like sugar in a hurricane.

description: Adenovirus (Ad) is a widely studied DNA virus, but the nucleoprotein structure of the viral genome in the cell is poorly characterized. Our objective is to study Ad DNA-protein associations and how these affect the viral life cycle. Most of the viral DNA condensing protein, protein VII, is lost within a few hours of infection and this loss is independent of transcription. Cellular histones associate with the viral DNA after removal of protein VII, with a preferential deposition of H3.3. Micrococcal nuclease accessibility assays at 6 hpi showed laddering of the viral DNA, suggesting the genome is wrapped in physiologically spaced nucleosomes. Although viral DNA continues to associate with H3.3 at late times of infection, the overall level of association with histones is greatly reduced. Knockdown of the H3.3 chaperone HIRA had no effect on the viral life cycle suggesting that other H3.3 chaperones are involved. Our studies have begun to elucidate the nucleoprotein structure of Ad DNA in the infected cell nucleus.
