description: From the 1930s to the 1970s, the Turner family of Breathitt County held a political and economic monopoly over their rural county in the mountains of eastern Kentucky. They were emblematic of the patronage, clientele, and kinship politics that characterized twentieth century eastern Kentucky. The family rewarded their supporters with jobs and other economic benefits in exchange for continued political support. Ervine Turner served as a state senator during the Great Depression and was later appointed circuit judge over a three-county district, his wife Marie served 38 years as superintendent of Breathitt County schools, and their children later emerged as prominent political leaders in the region. The Turners were loyal Democrats who embraced New Deal liberalism and its commitment to government-sponsored economic development. They cultivated political connections with prominent Democrats that extended as far upward as the White House. Throughout their time in power, the family gained loyal followers but also attracted vocal critics for alleged acts of fraud and corruption. By the 1960s, the family’s influence had grown so strong that some observers referred to them as the “Turner machine.” Political machines have traditionally been perceived as corrupt, wasteful, and inefficient. This thesis uses the Turner family as a case study for reexamining the traditional roles of political machines by highlighting the benefits that patronage politics can deliver in historically isolated places like eastern Kentucky. It argues that the Turner family served as mediators between their constituents and the government. Through their political connections, the Turners generated jobs and infrastructure for the people of Breathitt County. But this economic growth did not generate long-term development and came at the expense of reinforcing conditions of dependence, processes that ultimately perpetuated poverty in Breathitt County and eastern Kentucky.

description: This thesis aims to assess the supporting role social networks provide to divorced Saudi women who face after divorce challenges. After reviewing the impact that online social networks have on Saudi society and the legal context of divorce in Saudi Arabia, this study explores key issues faced by divorced Saudi women using a qualitative approach. Upon reviewing the limited amounts of literature and following two methodological phases, the key findings are: (1) identifications of primary challenges faced by divorced Saudi women namely; social, economic, psychological, and legal issues; (2) extraction of themes based on each identified issue, leading to the identification of four qualitative models; and (3) assessment of the supporting role social networks have in the identified themes of each issue.
Long-range Chained Epistasis in Influenza Viruses may not be Physically- but Functionally-mediated

description: In systems biology and genomics, epistasis characters the impact that a substitution at a particular location in a genome can have on a substitution at another location. This phenomenon is often implicated in the evolution of drug resistance or to explain why particular ‘disease-causing’ mutations do not have the same outcome in all in- dividuals. Hence, uncovering these mutations and their locations in a genome is a central question in biology. However, epistasis is notoriously difficult to uncover, es- pecially in fast-evolving organisms. Here, we present a novel statistical approach that takes inspiration from a model developed in ecology and that we adapt to analyze genetic data in a typically fast-evolving system: the influenza A virus. We validate the approach using experimentally-validated data: known interactions are recovered. We further evaluate the ability of our approach to detect epistasis during antigenic shifts or at the emergence of drug resistance. We show that in all cases, epistasis is prevalent in influenza A viruses, involving many pairs of sites linked together in chains, a hallmark of historical contingency. Strikingly, interacting sites are sepa- rated by large physical distances, which entail either long-range structural effects or functional tradeoffs, for which we find support with the emergence of drug resistance. Our work paves a new way for the unbiased detection of epistasis in a wide range of organisms by performing whole-genome scans.

description: The mammalian skin provides a necessary barrier between the organism and the environment, defending against loss of water and solutes, preventing the invasion of pathogens as well as protecting against chemical and physical assault. Claudin (Cldn)-based Tight Junctions (TJs) are the main functional part of the skin barrier. In particular, Cldn6 through its cytoplasmic tail has been shown to be important for barrier function. In other to further investigate the role of the Cldn6 tail in TJ-function, we developed Cldn6 mouse mutants carrying varying truncations of the Cldn6 tail. Both of these mice present with epidermal differentiation perturbations and delayed barrier function that is repaired later in life. These studies support the importance of the tail portion of the Cldn molecules in epidermal differentiation and barrier function. In addition, both of these mouse models are useful for the study of barrier function in preterm infants and in aging, with the hope of developing novel therapeutics for the alleviation of barrier dysfunction. Cdx is a family of homeodomain (HD) transcription factors (TFs) essential for many key developmental processes. In particular, Cdx2 is important for the establishment and maintenance of posterior identity in the developing endoderm. In spite of this, only a few Cdx targets in the developing endoderm have been discovered. In addition, the interplay between Cdx and its targets within the endoderm is poorly understood. In this study, we show that the forkhead box transcription factor, Foxa2 is a Cdx2 target. We also show that Foxa2 and Cdx2 physically and genetically interact to regulate a subset of genes that are implicated in endodermal development. These studies help to further our understanding of endoderm biology with the goal of developing new strategies to diagnose and treat diseases associated with defective endoderm development.

description: Cell migration is required for a number of physiological processes and is implicated in pathologies such as tumor metastasis. Cell motility is dependent upon dynamic actin reorganization, and is regulated by the Rho family of small GTPases. Rho GTPases are molecular switches that cycle between their active and inactive conformations. The best-studied members of this family are Rac1, RhoA, and Cdc42. Each is responsible for the formation of specific actin structures. Diacylglycerol kinases (DGKs) act at the membrane to convert diacylglycerol (DAG) and phosphatidic acid (PA), maintaining the balance of these two lipid second messengers. Previous studies from our lab have demonstrated that the ζ isoform of DGK facilitates the release of Rac1 and RhoA from their inhibitor, RhoGDI. Here we studied a closely related isoform, DGKι, using mouse embryonic fibroblasts (MEFS) in which the gene for DGKι had been deleted. Aberrations in cell morphology, spreading, and migration were identified in DGKι-null MEFs. We showed that the activity of Rac1 and RhoC, but not RhoA, was impaired in the absence of DGKι, yet only RhoC protein levels were affected. Reduced activation of these Rho GTPases was accompanied by defects in Rac1- and RhoC- related actin structures. These data demonstrate that DGKι, in addition to DGKζ, contributes to the regulation of GTPase activation and remodeling of the actin cytoskeleton.

description: Objectives: The majority of coronavirus disease 2019 mortality and morbidity is attributable to respiratory failure from severe acute respiratory syndrome coronavirus 2 infection. The pathogenesis underpinning coronavirus disease 2019-induced respiratory failure may be attributable to a dysregulated host immune response. Our objective was to investigate the pathophysiological relationship between proinflammatory cytokines and respiratory failure in severe coronavirus disease 2019. Design: Multicenter prospective observational study. Setting: ICU. Patients: Critically ill patients with coronavirus disease 2019 and noncoronavirus disease 2019 critically ill patients with respiratory failure (ICU control group). Interventions: Daily measurement of serum inflammatory cytokines. Measurements and Main Results: Demographics, comorbidities, clinical, physiologic, and laboratory data were collected daily. Daily serum samples were drawn for measurements of interleukin1β, interleukin-6, interleukin-10, and tumor necrosis factor-α. Pulmonary outcomes were the ratio of Pao₂/Fio₂ and static lung compliance. Twenty-six patients with coronavirus disease 2019 and 22 ICU controls were enrolled. Of the patients with coronavirus disease 2019, 58% developed acute respiratory distress syndrome, 62% required mechanical ventilation, 12% underwent extracorporeal membrane oxygenation, and 23% died. A negative correlation between interleukin-6 and Pao₂/Fio₂ (rho, –0.531; p = 0.0052) and static lung compliance (rho, –0.579; p = 0.033) was found selectively in the coronavirus disease 2019 group. Diagnosis of acute respiratory distress syndrome was associated with significantly elevated serum interleukin-6 and interleukin-1β on the day of diagnosis. Conclusions: The inverse relationship between serum interleukin-6 and Pao₂/Fio₂ and static lung compliance is specific to severe acute respiratory syndrome coronavirus 2 infection in critically ill patients with respiratory failure. Similar observations were not found with interleukin-β or tumor necrosis factor-α.
Horizontal-Branch Morphology and the Photometric Evolution of Old Stellar Populations

description: Theoretical integrated broadband colors ranging from far-UV to near-IR have been computed for old stellar systems from our evolutionary population synthesis code. These models take into account, for the first time, the detailed systematic variation of horizontal-branch (HB) morphology with age and metallicity. Our models show that some temperature-sensitive color indices are significantly affected by the presence of blue HB stars. In particular, B-V does not become monotonically redder as metallicity increases at given ages, but becomes bluer by as much as ∼0.15 mag because of the contribution from blue HB stars. Similar trends are also found in the Washington photometric system. In addition to appropriate age-sensitive spectrophotometric indices, the use of far-UV to optical colors is proposed as a powerful age diagnostic for old stellar systems with differing HB morphologies. Our models are calibrated in the B-V, V-I, C-T1, and M-T1 versus [Fe/H] planes, using low-reddened Galactic globular clusters (GCs) [E(B- V) < 0.2], and the relative age difference between the older inner halo Galactic GCs and younger outer halo counterparts is well reproduced. Several empirical linear color-metallicity transformation relations are assessed with our models, and it is noted that they may not be safely used to estimate metallicity if there are sizable age differences among GCs within and between galaxies. M3I GCs are found to be fundamentally similar to those in the Milky Way, not only in the optical to near-IR range, but also in the UV range. For globular cluster systems in two nearby giant ellipticals, M87 and NGC 1399, the current available photometric data in the literature do not appear sufficient to provide robust age discrimination. It is anticipated, however, that the detailed population models presented here, coupled with further precise spectrophotometric observations of globular cluster systems in external galaxies from the large ground-based telescopes and space UV facilities, will enable us to accurately estimate their ages and metallicities.
Working Within a Public Health Frame: Toward Health Equity Through Cultural Safety

description: This study explored how public health nurses (PHNs) work to address health inequities. Cultural safety was used as a theoretical lens. Methods for interpretive description were relied on for data collection and analysis. Data sources included interviews with 14 staff from an urban public health unit and document review of three policies. Two themes emerged: building relationships and working within a frame. Building relationships involved: delivering the message, taking the time, being present, the right nurse and learning from communities. The public health frame influenced the capacity of PHNs to address health inequities through: culture and stereotypes, public health standards, setting priorities, inclusion of priority populations, responding to change and (re)action through reorganization. Discursive formations of priority populations, and partnership and collaboration, were revealed. Findings highlighted downstream public health approaches to addressing health inequities. Importantly, embedding cultural safety as a framework for public health practice can guide upstream action.

description: This thesis details the fabrication of three different plasmon-polariton based devices: a plasmon-polariton Bragg grating (PPBG) biosensor, an intensity modulator incorporating grating couplers, and optically separated electrical contact, and finally an array of nanoholes in an ultrasmooth Au film. The biosensor involves a 35 nm Au stripe, lithographically stepped in width to produce a Bragg reflector. The waveguide is embedded in symmetric, Cytop claddings 8 µm thick. Channels are etched into the top cladding, exposing the waveguides and allowing for the integration of fluidics. The modulator involves a 20 nm Au pad, overlaid with 80 nm Au diffraction gratings, supported by an ultrathin (~3 nm) SiO2 insulator, on a p-doped Silicon wafer backed by an Al Ohmic contact. Electrical contact pads are separated from the waveguide by a thick dielectric (700 nm PMMA), and 2.5 µm vias in-filled with Au allow for electrical connection between the contact pads and waveguides. The nanohole array is machined by focused ion beam into an ultrasmooth Au film revealed by template stripping. The Au film is stacked on a thick film of Cytop between ~5 µm thick.
title: Unlocking imagination through maps: exploring the spatial imaginaries of food system transitions
Creators: name: Cross, Martha
Publisher: name: University of Reading
Year: 2024

description: Relocalisation is often seen as an antidote to the problems associated with the 
‘globalised’ food system. Shortening the distance between food production and 
consumption requires a significant shift in food systems thinking and practice. 
This thesis is concerned with how these rescaled food systems are imagined by 
actors seeking to move away from the ‘global’ and towards the ‘local’, and the 
role of these visions in transforming food systems. It fuses sustainability 
transitions – the process of change, usually from a less towards a more desirable 
state, with spatial imaginaries – the ways we collectively conceptualise, frame 
and experience spaces and places. The research focuses on the transitions 
sought by people working within and around UK food partnerships. It combines 
document review, interviews and spatial mapping methods to uncover and 
explore the desired destinations of transition – what I refer to as spatial 
imaginaries – how these visions are legitimised and justified, and by whom. It 
builds a picture of the conditions required for an imaginary to take hold, reflecting 
on the interaction between vision, policy and practice and the tensions that arise. 
In doing so, it responds to an identified research gap to better understand the role 
and influence of spatiality, agency and legitimacy in reimagining food system 
transitions. More specifically, it intersects with a current debate on the role of food 
partnerships in transitioning food systems through rescaling, by highlighting the 
value in more carefully considering our imagined food futures. The research 
makes two key original contributions. Firstly, by exploring the ‘relational triangle’ 
between spatial imaginaries, rescaling and transition, it sheds light on how the 
power of imagination and the politics of rescaling are harnessed to reconceive, 
shape and validate food system change. It identifies a complex and dynamic 
relationship between personally-held visions, written strategies and common 
spatial imaginaries and assesses the implications in research and practice terms. 
Secondly, the spatial mapping approach brings a unique dimension to exploring 
the visions, perspectives and actions of actors seeking change. The approach 
can help identify bounded thinking, avoid the pitfalls of localism and create richer 
and more inclusive and imaginative shared spatial visions of food system 
transitions.

description: Unique characteristics of cluster randomized trials (CRTs) complicate the interpretation of standard research ethics guidelines. Variable interpretation by research ethics committees may further complicate review and conduct. An international web-based survey was administered to corresponding authors of 300 randomly sampled CRT publications. We investigated ethics review and consent practices, investigator experiences with ethics review, and the perceived need for CRT-specific ethics guidelines. The response rate was 64%. Ethics review and consent were under-reported in publications. Ethics approval was obtained in 91%, and consent from individual and cluster level participants in 79% and 82% of trials. Consent varied by level of experimental intervention, data collection, and cluster size. Respondents cited variability among ethics committees (46%), and negative impacts of ethics review on their studies (38%). The majority perceived a need for ethics guidelines (73%), and guidance for ethics committees (70%). CRT-specific ethics guidelines are required to ensure practices meet ethical standards.
Revising revisionist history: the 'Maori Achievement' and recent historiographical developments on 'The New Zealand Wars'
Creators: name: Veracini, Lorenzo
Publisher: name: Swinburne
Year: 2024

description: James Belich's seminal redescription of nineteenth century Maori-Pakeha conflict has recently been the subject of a spate of interpretative challenges. These critiques have focused especially on his notion that the Maori war effort of the 1860s had been the first example of an effective military response to the tactical necessities brought about by modern warfare. Since its publication in 1986 and despite these recent attacks, however, Belich's theses on the 'Maori Achievement' have hegemonised the recurrent debate on the origins of Aotearoa/New Zealand's exceptionality. The first part of this paper assesses this recent criticism of Belich's rendition of the land wars that engulfed Aotearoa/New Zealand during the latter half of the nineteenth century. The second part constitutes - fifteen years after the publication of The New Zealand Wars - an analytical reading of the historiographical role played by Belich's revisionist interpretation.

description: A growing body of literature recognises the profound impact of adversity on mental health outcomes for people living in rural and remote areas. With the cumulative effects of persistent drought, record-breaking bushfires, limited access to quality health services, the COVID-19 pandemic and ongoing economic and social challenges, there is much to understand about the impact of adversity on mental health and wellbeing in rural populations. In this conceptual paper, we aim to review and adapt our existing understanding of rural adversity. We undertook a wide-ranging review of the literature, sought insights from multiple disciplines and critically developed our findings with an expert disciplinary group from across Australia. We propose that rural adversity be understood using a rural ecosystem lens to develop greater clarity around the dimensions and experiences of adversity, and to help identify the opportunities for interventions. We put forward a dynamic conceptual model of the impact of rural adversity on mental health and wellbeing, and close with a discussion of the implications for policy and practice. Whilst this paper has been written from an Australian perspective, it has implications for rural communities internationally.

description: The parathyroid hormone related protein (PTHrP) and Indian Hedgehog (IHH) are two secreted molecules, acting as paracrine factors during embryonic development and post-natal growth of endochondral bones. PTHrP and IHH are essential factors for the regulation of chondrocyte proliferation and differentiation. However, it has previously been shown that PTHrP and IHH are also expressed in the chick and mouse embryos intramembranous bones, which do not form through a cartilage intermediate and in which chondrocytes are absent. Similarly, the zebrafish orthologs, pthrp1 and ihha, are also expressed during the regeneration of the intramembranous bones of the fin rays of the zebrafish caudal fin. This surprising observation led us to further analyze the expression and function of pthrp1 and ihha in the regenerating fin rays. Gene expression analysis using in situ hybridization shows that pthrp1 is expressed in a stripe of cells located within the domain of expression of ihha in the newly differentiating osteoblasts in the regenerating fin rays. Also, pthrp1 expression is observed at the level of the joints between the bone segments forming the rays and co-localizes with the expression domain of evx1, a transcription factor that has been implicated in the formation of joints in the caudal fin. Furthermore, RT-PCR analyses show that pthrp2 and the pthrp receptors mRNA (pth1r, pth2r and pth3r) are also present in the fin regenerate. Finally, functional analysis shows that the knockdown of pthrp1 or ihha expression by electroporation of morpholinos induces a delay of the regenerative outgrowth of the fin. These results suggest that pthrp1 and ihha may be involved in the regulation of proliferation and differentiation of chondrocyte-like osteoblasts in the fin rays, playing a role similar to that described in the mammalian growth plate of endochondral bones. In addition, pthrp1 is possibly an important factor involved in the formation and maintenance of joints of the dermal bones of the fin rays.

description: Incorporating a psychological contract perspective into information technology projects, this study intends to explore the elements of the software publisher-reseller-end user psychological contract in the context of IT projects and contribute to existing literature in the field of IT psychological contracts. The data for this study was collected via 10 interviews conducted across 5 different cases. Interviewees were asked to describe IT projects they were recently involved in and outline what they perceived to be their obligations towards the other stakeholders and likewise, the obligations of the other stakeholders upon them. Interviews were transcribed and coded in accordance with existing IT project psychological contract elements derived from literature. The results of this study provided support to all psychological contract elements of the existing model and suggest refinements to better capture the perceived obligations of stakeholders in IT Projects. Furthermore, we observe that while the resellers’ and software publishers’ psychological contracts with end users conformed to the obligations expected under the model of supplier-customer relationships, the software reseller-software publisher psychological contracts reciprocally contained elements of both supplier and customer obligations. Finally, the findings of this study revealed that critical to the success of IT projects are the elements of transparency, accuracy, dedication, knowledge and responsibility.

description: Injectable biomaterials have emerged as a treatment for myocardial infarction (MI). They can be applied either as an enhancement for cell therapy or as a stand-alone treatment for MI. The main focus of this study was to apply circulating angiogenic cells (CACs) with or without an injectable collagen matrix for MI treatment in a mouse model. Furthermore, a collagen-chitosan matrix was tested for modulating the myocardial maladaptive remodeling post-MI. First, the in vivo thermo-gelling and retention properties of the collagen matrix were validated using positron emission tomography (PET) tracer and quantum dot (Qdot) labelled matrix in MI mouse hearts. The therapeutic potential of the matrix ± CACs was then tested in a mouse MI model. The results showed that CACs-only and matrix-only treatments were associated with cardiac function preservation. However, in combination, CAC + matrix therapy had a synergistic effect and significantly improved cardiac function (echocardiography), perfusion and viability (PET scan), increased cell engraftment and arteriole density, and reduced the infarct size. CAC-matrix interaction through the integrin alpha2 receptor was essential for the observed therapeutic effect. In a third study, the addition of chitosan (a polysaccharide) to the collagen matrix was shown to reduce maladaptive remodeling post-MI by limiting cardiac fibroblast-to-myofibroblast differentiation and scar formation. In conclusion, these collagen-based hydrogels hold promise to enhance cardiac repair as a delivery scaffold for therapeutic cells, and/or as a stand-alone treatment, which can actively modulate the environment including the fibrotic process after MI.

description: Carbon fibre reinforced composites are known for their high specific strength-to-weight ratio and are of great interest to the aerospace industry. Incorporating these materials into the fuselage, like in Boeing's 787 "Dreamliner", offers considerable weight reduction which increases flying efficiency, and reduces the cost of flying. In flight, aircraft are often subject to lightning strikes which, in the case of composites, can result in localized melting given the high resistive nature of the material. Aerospace carbon fibre composites often incorporate a metallic mesh or foil within the composite layers to dissipate the electrical charge through the large aircraft. The damage to the aircraft is minimized but not always eliminated. This research aims to elaborate a practical technique to deposit thin layers of conductive material on the surface of aerospace grade composites. Using Cold Gas Dynamic Spray (CGDS), such coatings could be used to repair damaged components. An experimental research approach was used to develop metallic coated composites. Using the CGDS equipment of Centerline (SST-P), specific parameters (such as gas temperature and stagnation pressure) were determined for each type of metallic coating (tin-based & copper-based). The use of bond coats was explored in order to attain the desired coatings. Once optimized, these coatings were evaluated with respect to their corrosive, adhesive, and electrical properties following industry standards.

description: This thesis encompasses a collection of four pieces of work on wave-particle duality, weak-value-assisted tomography, high-dimensional quantum key distribution, and phase-only holograms. In the work on duality, we derive a novel duality relation, and we sketch a thought experiment that leads to an apparent violation of the duality principle. In the project on tomography, we perform a state determination procedure with weak values, and we study the accuracy of the method. In the quantum cryptography project, we optimize an experimental implementation of a quantum cryptography system where two parties share information with the orbital angular momentum degree of freedom of entangled photon pairs. Finally, in the work on holography, we establish the exact solution to the encryption of a phase-only hologram, and experimentally demonstrate its application to spatial light modulators. The four projects provide improvements on measurement procedures in applied and fundamental quantum mechanics.

As the leading international online astronomy program, Swinburne Astronomy Online (SAO) is distinctive in that students from the program’s country of origin are in the minority among a cohort located in over 30 countries, taught by instructors who are also located around the world. We discuss factors that have helped make SAO successful internationally, plus issues that arise when teaching astronomy in an international context. This international approach is not as general as it might seem: English is the SAO language of instruction and many of its far flung international students are expatriate English speakers, so non-native English speakers (NNES) are actually in a very small minority. SAO features primarily student lead discussion in asynchronous discussion forums with emphasis on assessment tasks that reward communication skills - design features that may not always be appropriate outside native English speaking cultures. We present results of a survey of NNES participants, plus analysis of their forum contribution rates and performance in assessment tasks. We conclude by briefly raising issues likely to be faced when offering online programs like SAO to international cohorts that include more linguistically and culturally diverse populations of participants.

description: Indoor air concentrations of formaldehyde, furfural, benzaldehyde, and 11 aliphatic aldehydes (C2-C11) were measured in residences of 639 participants in the German Environmental Survey for Children and Adolescents 2014-2017 (GerES V). Sampling was conducted using passive samplers over periods of approximately seven days for each participant. The most abundant compounds were formaldehyde and hexanal with median concentrations of 24.9 (micro)g m-3 and 10.9 (micro)g m-3, respectively. Formaldehyde concentrations exceeded the Guide Value I recommended by the German Committee on Indoor Guide Values (Ausschuss für Innenraumrichtwerte - AIR) (0.10 mg m-3) for 0.3% of the participating residences. The sum of aliphatic n-aldehydes between C4 (butanal) and C11 (undecanal) exceeded their Guide Value (0.10 mg m-3) for 2.0% of the residences. The geometric mean concentrations of most aldehydes were lower than in the earlier GerES IV (2003-2006) study. Formaldehyde and hexanal concentrations, however, were comparable in both studies and showed no significant difference. Indoor aldehyde concentrations did not exhibit significant correlations with factors collected in questionnaires, such as the age of the participants, their socio-economic status, the location of the residence (former East/West Germany), migration background, tobacco exposure, and the type of furniture used. The validity of the passive sampler measurements was verified against active sampling techniques in a test chamber experiment. © 2021 The Authors
Graphic intervention: interrogating newspaper design as a site of social construction
Creators: name: Jones, Sarah
Publisher: name: Swinburne
Year: 2024

description: In 2004 The Age newspaper proclaimed that it is 'The world's most liveable newspaper'. This proclamation firmly situated the newspaper in the realm of the domestic. To be classified as liveable, a shelter or structure must be deemed fit to live in. It must facilitate a sense of ease and a moderate degree of comfort. A liveable setting provides its occupants with a sense of security and control as well as the confidence to invite others into that space. This liveable structure in turn becomes a social structure. When we are comfortable and confident with the quality of our setting, we invite others in, forming social networks, which provide companionship and community. This Masters project investigates how graphic design systems and structures influence and shape our emotive and social relationship with society. It examines how graphic design within ephemeral artefacts of the everyday, such as the newspaper, gives visual expression to social myths, shaping narratives of ordinary people's lives into soap operas, which we consume voraciously and somewhat unconsciously. By analysing how design functions within the newspaper, framing, interpreting and emotionally manipulating everyday tragedies such as love triangle murders or, what is here termed modern, gothic tales, this thesis seeks to highlight the role of design in cultural and social production. It uses a series of exhibitions and publications to critically interpret and rework the formal and communication strategies of newspaper design to reveal how graphic design can be used as a strategy for cultural intervention. The central aim of the project is to challenge the anonymous, if not unseen, nature of graphic design and its central role within the media in shaping popular and consumable images of community and citizenship.
Young Australians: building social capital through membership of organised groups

description: Social capital is defined as norms of trust and reciprocity held by a group of individuals or organisations. Family, neighbourhood and friendship realms are often informal platforms upon which young people develop their social capital. In addition, membership of organised groups has been central in discussions of social capital since Robert Putnam (2000) asserted that levels of social capital in the United States of America had declined by pointing out that Americans had stopped attending meetings in volunteer associations and social clubs. Using the perspective of bonding and bridging social capital as starting bases for cultivating social capital, this thesis focuses on the mobilisation of social capital in different social settings. Also, this study examines whether young people are likely to be active members of organised groups if they have generated higher levels of social capital with their family members, friends and neighbours. Another focus of this thesis is to investigate whether group membership makes a difference to young Australians’ levels of civic engagement and generalised trust. Young Australians and permanent residents aged 16 to 25 (N = 283) participated in this study through an online survey. The findings support previous literature, which found members of organised groups to be more trusting and reciprocative in general than those who do not participate in any organised groups. Indeed, passive membership is as important as active membership of organised groups for promoting civic engagement and generalised social capital. Family social capital may serve as a starting base for young people to generate social capital with their friends. However, the data analysed in this thesis show that those who generate very high social capital with their family members are not likely to have higher social capital in all other social settings. Indeed, my findings suggest that social capital among friends and neighbours are important in extending social capital among people in general. Thus, policy makers should turn their focus to promoting social capital among neighbours by creating safe, cohesive, active and stable neighbourhoods, because these four characteristics are identified as important in increasing levels of social capital among neighbours. Finally, it is also important for policy makers to promote organised groups for young people to participate in.
Au croisement des mots, des regards et des corps : représentations équivoques du féminin dans le théâtre de Brigitte Haentjens

description: Depuis le début de sa carrière, la metteure en scène Brigitte Haentjens favorise une approche du théâtre qui allie des textes percutants à un jeu physique rigoureux. Surtout au sein de Sibyllines, sa propre compagnie, elle développe cette esthétique corporelle tout en explorant le féminin dans son choix de textes et ses distributions. Par l’utilisation de topoï dans la création d’images scéniques – la fragmentation des textes, le jeu frontal, la répétition et la juxtaposition des paroles ou des gestes – Haentjens établit plusieurs degrés de lecture simultanés. Chaque système scénique vient ainsi agir sur le corps du comédien de manière à créer des images complexes et conflictuelles. La présente étude donne un aperçu des divers procédés qui installent une ambiguïté dans la représentation du corps féminin chez Haentjens. Pour ce faire, nous nous référerons à des exemples tirés des spectacles Hamlet-Machine (2001), La Cloche de verre (2003) et Médée-Matériau (2004), qui constituent un cycle précis dans le théâtre de Sibyllines, où les petites salles et l’intimité de la scénographie permettent de perturber le rapport établi entre spectateurs et comédiens.

Bridging Troubled Waters: Examining Culture in the Canadian Red Cross' Swimming and Water Safety Program
Creators: name: Rich, Kyle
Publisher: name: Université d'Ottawa / University of Ottawa

Subjects: Cultural Safety
Inclusive Sport/Recreation Programming
Managing Diversity

description: The Canadian Red Cross (CRC) offers its Swimming and Water Safety Program throughout Canada. The program is delivered by over 35 000 active instructors to over one million participants every year. The research in this thesis is part of a collaborative, interdisciplinary project in partnership with the CRC that examined ways to improve programming for cultural and ethnic minority populations. The thesis is written in the stand alone paper format. The first paper evaluates the program’s content, through a critical whiteness lens, to identify obstacles to offering effective programming to people of diverse cultural and ethnic backgrounds. Based on these findings, I created and piloted a cultural safety training module for program instructors. The second paper then evaluates the effectiveness of this training module to provide recommendations for the CRC to optimize its management of diversity within its organization and aquatics facilities across the country. Collectively, this thesis bridges both understandings of Eurocanadian and whiteness discourses as well as critical whiteness and organizational theories to more holistically understand processes of inclusion, exclusion, accommodation, and the management of diversity in the context of a nation-wide Canadian sport and recreation program.
