Nano Enhanced Surface Modification Of Titanium Dental Implants For Improving Osseointegration And Biocompatibility, Ranj Salaie

School of Biological and Marine Sciences Theses

Dental implants are prone to bacterial colonisation and infection which subsequently cause dental implant failure. Coating the dental implant with an antibacterial agent and a biocompatible agent can inhibit the bacterial colonisation and infection without disturbing the biocompatibility of the implant. This study aimed to coat medical grade titanium alloy implants with silver and hydroxyapatite (HA) nanoparticles. The reason for using silver was to introduce antibacterial activity to the coated dental implants; and then using HA to preserve biocompatibility and manage the silver exposure of the primary human osteoblast cells. Medical grade titanium alloy discs measuring 15 mm in diameter …

The Biological Effects Of Engineered Nanomaterials On Soil Organisms: Surface Coating And Age Matter, Kristi Tatsi

School of Biological and Marine Sciences Theses

Engineered nanomaterials (ENMs) have been increasingly used in various applications. Often, the ENMs are functionalised with a surface coating to enhance their properties. Decades of research has provided information on mostly pristine and unmodified ENMs, while ecotoxicity of coated ENMs and how their hazard changes with age in soils is still uncertain. The thesis aimed to determine the toxic effects and bioaccumulation potential of CuO ENMs and CdTe quantum dots (QDs) with different chemical coatings (carboxylate, COOH; polyethylene glycol, PEG; ammonium, NH4+) on the earthworm (Eisenia fetida), and compare the effects to their metal salt (CuSO4) or micron-sized counterpart. Then, …

Caught In The Frame: A Critical Analysis Of Australian Media Representations Of The Israeli-Palestinian Conflict 2014–2015, Mayyada Mhanna

Theses: Doctorates and Masters

Despite the many current conflicts in the Middle East and the world, the Israeli- Palestinian conflict is still one of the most significant conflicts of the modern era. The reasons for this include the history and violence of this conflict and the lack of practical solutions for it. The significance of this conflict is reflected in its prevalence in many disciplines, such as political science and media studies. Related literature shows that Australian media coverage of this conflict has not been investigated thoroughly. Hence, this study attempts to bridge this gap in literature, aiming to identify how Australian media portray …

Qualitative data were collected from in-depth ethnographic interviews with 25 women in Perth, Western Australia, to illuminate an understanding of their holistic health beliefs and practices, perceptions of appearance and health ideals, as well as their understandings of positive body image. Thematic analysis of the data through Nvivo revealed several overarching themes, demonstrating how certain aspects of holistic health culture may encourage or dissuade the development …

Design, Implementation And Evaluation Of The Impact Of A Body Image Professional Development Program For Early Childhood Educators, Karen Lombardi

Theses: Doctorates and Masters

Poor body image is a serious public health concern globally, and may lead to the development of poor mental and physical health, as well as eating disorders. Body image concerns were once believed to arise during puberty, though it is now reported children as young as three years of age present with such problems. Early intervention is therefore an important strategy to improve mental and physical health outcomes for very young children, and educators are an obvious conduit to build confidence, self-esteem and resilience of such children. In order for them to adequately fulfil this role, educators must first understand …

Young People Who Fireset In Western Australia: Peer Group Influences And Impulsiveness Trump Consequences, Catherine Analise Timms

Theses: Doctorates and Masters

The paradoxical character of fire is perfectly captured by the juxtaposition between the initial ease and excitement of lighting fires, and fire’s destructive and uncontrollable nature. Australia is fire prone with its hot, dry climate, volatile vegetation and urban sprawl surrounded by bushland. Since an estimated 50% of fires lit in Australia are deliberate (Stanley & Read, 2016) the problem of intentional firesetting cannot be overstated. This thesis argues that youth firesetting requires both macro- and microlevel approaches to appreciate the complexities of the problem, and aims to identify applicable and directed responses to minimise youth firesetting. Study one analysed …

The purpose of this thesis is to explore the potential of SM for project management and to understand some of the difficulties that arise from SM use. The research specifically investigated how SM is being used for project activities and the maturity of the management processes that govern SM use. Implications for …

Exploring Poor Outcomes From Quality Assurance Programs – An Analysis Based Around The Concept Of Mechanisms And The Theory Of Constraints (Toc) Thinking Process (Tp), Layla M. M. B. Al-Hameed

Theses: Doctorates and Masters

Quality programs have been used by organisations since their advent in the 1930s and continue to be implemented to achieve various goals. For example, according to the International Organization for Standardization (2015) and the CASRO Institute for Research Quality (2016), organisations aim to reduce costs, gain a competitive advantage, improve the quality of their processes and products, and enhance profitability through attaining such accreditations. ISO accreditations have also been used to ensure compliance with market requirements (Williams, 2004). However, a major challenge in implementing these programs, referred to in this thesis as ‘Quality Assurance Programs’ (QAPs), is the gap that …

No-One Was Watching: A Collection Of Short Fiction And Stories Beyond The Gates: An Exegesis, Ann Elizabeth Horner

Theses: Doctorates and Masters

This research project asserts the primacy of creative practice as a key method of enquiry and explores how fictional stories, re-imagined from historical events of the mid-twentieth century, may provide different ways of viewing a world which was inhabited by once-silenced children, now known as the ‘forgotten Australians’. To this end, the thesis is made up of a creative component in the form of a book-length collection of short fiction that is accompanied by a critical component positioning the thesis contextually, theoretically and methodologically. The research reveals overwhelming evidence of a culture of endemic abuse within Australian child welfare organisations …

Reading Between The Crimes: Online Media’S Representation Of Aboriginal And Torres Strait Islander People’S Interaction With The Criminal Justice System In Post-Apology Australia, Jonathan Cannon

Theses: Doctorates and Masters

Australian research confirms that Aboriginal and Torres Strait Islander people experience high levels of social inequality, racism and injustice. Evidence of discrimination and inequality is most obvious within the criminal justice system where they are seriously over-represented. The Australian news media plays a large part in reinforcing Aboriginal and Torres Strait Islander inequality, stereotypes and racist ideology within specific situations such as the Northern Territory Emergency Response and the Redfern riots. This study widens the scope from how the media reports a single criminal justice event to how the media reports Aboriginal and Torres Strait Islander people’s interaction with the …

The Cryopreservation Of Human Semen, And Subsequent Evaluation Of A Commercially-Available Device To Isolate Motile Sperm, Callum Andrew Robinson

Theses: Doctorates and Masters

The cryopreservation of human semen is a vital asset in assisted reproductive technologies (ART). Although advances have been in the freezing of sperm, further refinement is both necessary and ongoing. Computer-assisted semen analysis (CASA) has been increasingly utilised in both research and diagnostic however there are a range of variables that must first be controlled in order to produce reliable measurements. Following thawing, sperm must be isolated from both the original seminal plasma and the cryoprotectants; the two most used isolation methods include density gradient centrifugation (DGC) and the swim-up method.

The present thesis sought to investigate the following areas …

The Beloved: A Documentary Film On The History And Aftermath Of Fremantle’S Rajneesh Sannyasin Community – And – Hidden Realities: Transcendental Structures In Documentary Film: An Exegesis, Joseph London

Theses: Doctorates and Masters

This creative work and its associated exegesis examines the concept of what I have termed a ‘transcendental structure’ in relation to a documentary film form, and what outcomes, specific to a non-fiction mode of representation, result from the application of this structure. A transcendental structure in film has a long history of investigation and interpretation in narrative fiction film theory and practice, but is substantially absent from documentary scholarship. The topic appears, in different forms, in the critical writings of Zavattini (1940), Bazin (1946), Pasolini (1965), Schrader (1972), Deleuze (1985), and more recently, Perez (1998) and Minghelli (2016). All of …

Contextualizing Social Power Research Within Organizational Behavior, Michael Schaerer, Alice J. Lee, Adam D. Galinsky, Stefan Thau

Research Collection Lee Kong Chian School Of Business

Although there has been tremendous scientific interest in social power, much of this recent research has relied on experiments in context-poor settings. However, organizations – a context in which power differences emerge naturally – are more complex and dynamic. The current review discusses whether and how defining organizational features at the intrapersonal level (multiple dimensions of hierarchy, dynamics over time, attentional demands), interpersonal level (interdependence, repeated interactions), and organizational level (accountability, culture, virtual work) moderate the effects of power. We also discuss ways to systematically incorporate organizational complexities into the study of social power and recommend fruitful avenues for future …

Heads Will Roll! Routes To Effective Trust Repair In The Aftermath Of A Ceo Transgression, Donald L. Ferrin, Cecily D. Cooper, Kurt T. Dirks, Peter H. Kim

Research Collection Lee Kong Chian School Of Business

CEO transgressions are a common storyline in today's business press. Such incidents result in the need to repair trust for both the CEO and the organisation that the CEO leads. Existing empirical research on trust repair has focused primarily on interpersonal trust, resulting in a body of knowledge that provides many insights to the errant CEO but few insights for those who aim to repair trust in the organisation. Since organisations also need to regain the trust of stakeholders after a CEO transgression, research on organisational trust repair is clearly warranted. Organisations have options for trust repair that are not …

The Indigenization Of Crisis Response Strategies In The Context Of China, Augustine Pang, Yang Hu

Research Collection Lee Kong Chian School Of Business

Crisis communication, which has been dominated by a practical perspective, has become a nexus where theory meets application. Despite mounting interest in theoretical studies, crisis communication lacks cultural contextualization. Asian communication researchers have advocated for the need to indigenize communication, drawing relevance to cultural influences. In this study, the authors explored indigenous corporate crisis response strategies in the context of China through nine cases. Three Chinese indigenous strategies were identified through qualitative content analysis of corporate crisis responses. These strategies are “barnacle,” “third-party endorsement,” and “setting up new topics.” The differences with Western frameworks were also discussed.

Theoretical Principles Relevant To Assessment Center Design And Implementation, George C. Thornton, Filip Lievens

Research Collection Lee Kong Chian School Of Business

Decades ago, assessment centers (Acs) originated by applying the best available evidence and theory to the assessment of managerial performance dimensions. The objectives of this chapter are to take stock of these existing theoretical principles, present additional theoretical principles that have emerged in recent times, and describe the practical implications of these principles for effective Ac design and implementation. Thus, while all Acs include several essential elements, developing and implementing a specific Ac involves a complicated set of choices. This chapter shows how these choices can be guided by theories relevant to the Ac method as a whole and each …

Modifikasi Pembobotan Systemic Important Score Dengan Principal Component Analysis, Samsul Anwar

Jurnal Ekonomi dan Pembangunan Indonesia

The Financial Services Authority regulation No.46/POJK.03/2015 states that the calculation of Systemic Important Score (SIS) of a bank uses the same weighting for all three indicators: size, interconnectedness, and complexity. It disowns the possibility that one those indicators may give more contribution in determining the data structure of SIS assessment component than the others. This study offers an alternative weighting system to calculate SIS. The weighting system is based on eigenvectors of Principal Component Analysis by starting with standardizing the data. The simulation results show that the order of banking systemic levels in Indonesia from the highest are banking BUSN …

Public Ownership And The Local Economy, Jess Cornaggia, Matthew Gustafson, Jason Kotter, Kevin Pisciotta

Faculty Publications

We provide evidence that a firm’s transition from private to public ownership stunts local economic growth, especially in less populated and poorer areas. After accounting for endogeneity in the ownership decision, areas hosting companies that go public experience muted growth in employment, establishments, population, and wages, relative to areas where firms file to go public and remain private. Establishment-level analyses reveal that transitioning to public ownership causes firms to geographically diversify their establishments and employee base. These findings are consistent with public ownership reducing a firm’s reliance on local agglomeration economies, to the detriment of the local community.

Saving Face On Facebook: Privacy Concerns, Social Benefits, And Impression Management, Jeffrey G. Proudfoot, David W. Wilson, Joseph S. Valacich, Michael D. Byrd

Faculty Publications

The nearly ubiquitous use of online social networks generally entails substantial personal disclosure and elicits significant privacy concerns. This research uses Social Exchange Theory and the impression management (IM) literature to examine how privacy concerns can be counterbalanced by the perceived social benefits afforded by a social network’s ability to support IM. We frame social network use as an attempt to engage in IM, and we highlight the importance of a social network’s IM affordances in predicting social benefits from, and disclosure through, a social network. We test our model with a sample of 244 Facebook users, finding support for …

The Protective Effects Of Social Support And Engagement Coping Strategy On The Relationship Between Perceived Discrimination And Psychological Distress Among Chinese Migrant Children, Jin-Liang Wang, Hsing-Fang Hsieh, Shervin Assari, James Gaskin, Detlef H. Rost

Faculty Publications

This study was aimed to figure out whether perceived stress mediates the relationship between perceived discrimination and psychological distress among Chinese migrant children and whether social support and engagement coping moderate the detrimental effects of perceived discrimination on psychological distress. The sample comprised 813 middle-school students (482 migrant children, 331 non-migrant children) from three schools in Southwest China. The results indicate that migrant children’s perceived discrimination and perceived stress are associated with psychological distress, and perceived stress does not mediate the relationship between perceived discrimination and psychological distress. Both social support and engagement coping are inversely related to psychological distress …
