Factors Affecting The Survival And Implantation Of Human Blastocysts Following Vitrification, Hamish Barblett

Theses: Doctorates and Masters

The increased cell numbers, presence of the blastocoel and rapid cell re-organisation have required the development of specific survival criteria post warm to effectively select the most viable blastocyst for transfer. Pre-freeze blastocyst expansion and post warm re-expansion have been shown to contribute significantly to the chances of an implantation and subsequent live birth. The aim of this study was to explore factors that influence the outcome of blastocyst transfers after vitrification and warming, and hopefully improve outcomes by further applying improvements in future cycles. Variables from 8 years of vitrified/warmed blastocysts were retrospectively compiled and analysed to determine the …

Calculation Of Critical Water Flow Rates For Wildfire Suppression, Greg Penney, Daryoush Habibi, Marcus Cattani, Murray Carter

Research outputs 2014 to 2021

Predicting water suppression requirements and its impacts on firefighting strategies and logistics within the urban environment has been the subject of many previous studies, however the same level of research has yet to be applied in the realm of wildfire suppression. To work towards addressing this knowledge gap, this paper provides guidance for Incident Controllers in relation to critical water flow rates required to extinguish large wildfire across a wide range of forest fuel loads, fire weather and active fire front depths. This is achieved through mathematical empirical analysis of water flow rates required for head fire suppression during 540 …

Causes And Possible Consequences Of Hybridisation In Angelfishes At Christmas Island, Federico Vitelli

Theses: Doctorates and Masters

The angelfishes (family Pomacanthidae) have the greatest proportion (~30%) of hybridising species, compared to other families of reef fishes, with 26 species implicated in hybridisation. However, very little is known about hybridisation in angelfish, especially in terms of fitness of the hybrids and possible ecological consequences. Hybrids between three species (C. flavissima, C. eibli and C. vroliki) in the genus Centropyge have previously been reported from Christmas island, where these have been observed in heterospecific harems and interbreeding. This provides the unique opportunity to examine the breakdown in assortative mating in marine fishes. The broad aim of this …

Job Embeddedness And Turnover Intentions: The Moderating Role Of Affectivity Traits, Career Stages And Perceptions Of Organisational Politics, Emmanuel Twumasi Ampofo

Theses: Doctorates and Masters

The study tested the applicability of job embeddedness (JE) theory in Ghana. It also examined moderating effects of affectivity traits, career stage and perceptions of organisational politics (POP) on the JE–turnover intentions relationship. Analyses revealed that composite JE and its dimensions and sub-dimensions (except community fit) were negatively related to turnover intentions. Affectivity traits, POP and career stages moderated the JE–turnover intentions relationship. The study expands the predictive validity of JE to Ghana and adds to the few moderators that have been identified in previous studies. Strategies for increasing managerial employees’ embeddedness and reducing their turnover are proposed.

Teachers’ Perspectives On The Identification Of, And Provisions For, Gifted And Talented English As An Additional Language Students, Lucy Byramji Hands

Theses: Doctorates and Masters

In recent years, Western Australian State schools have seen a sharp rise in the number of students who use English as an Additional Language (EAL). Almost one-third of them have been identified as having culturally and linguistically diverse ancestry (Australian Bureau of Statistics, 2016). Many are gifted and talented (GT). However, while it has been widely acknowledged that GT abilities can be found in all ethnic, cultural, and linguistic groups, barriers such as socioeconomic circumstances, stereotypes, political climate, language backgrounds and a myriad of factors can influence the recognition, identification and full participation of EAL students in gifted and talented …

An Exploration Of The Critical Success Factors Associated With Implementing A Public Health Plan In Local Governments Within Western Australia, Anne Polley

Theses: Doctorates and Masters

Public Health planning in local governments in Western Australia (WA) is a relatively new approach to addressing local health needs. The Western Australian Public Health Act came into effect in 2016. The Public Health Act 2016 encompasses a range of legislative requirements, some of which include the development of Local Public Health Plans. A range of roles within the local government workforce therefore are likely to require support to plan and implement Public Health Plans, which in the past have not directly been a component of their role. There is limited understanding and evidence of the barriers and enablers that …

Video Cued Teacher Reflection To Guide Enhancement Of Student Engagement In A Specialist Primary Classroom, Tamara Nicole Standley

Theses: Doctorates and Masters

Specialist primary teachers confront the challenging task of teaching extensive learning content of the Western Australian Curriculum, within limited weekly timetabled lessons. This was the motivating factor behind this study aimed at investigating the use of self-tracking video technology as a tool for teacher reflection, to guide enhancement of student engagement and learning in the specialist classroom. Reflective practice is integral to monitoring and improving teaching pedagogy but without an effective reflection tool, it can potentially be a waste of time.

The capacity for a teacher to engage in reflection-on-action through real time video analysis enables a deeper understanding of …

Performance Practice In Hungarian Folk Music And Its Relationship To The Style Hongrois, Teresa Vinci

Theses: Doctorates and Masters

This study investigates style and performance practice within the oral traditions of Hungarian folk music, and explores intersections with the nineteenth-century idiom style hongrois. Interviews, lessons, and workshops were undertaken as part of a practice-based immersive research experience, and comparisons with the style hongrois made via analysis of scores and recordings of Jeno Hubay (1858-1937). The research strives towards an ‘Historically Informed Performance’ specific to these styles, and explores how they can inform each other. Findings are presented through a dissertation and a CD recording “Never Far Away…” comprising the researcher’s violin performance as leader of an Hungarian folk …

Characterization Of Hypothetical Protein, Sausa300_1759, From A Common, Community-Associated Methicillin Resistant Staphylococcus Aureus Strain, Usa300, And A Contact Lens Case Study, Ashley Nikol Clodfelder

All-Inclusive List of Electronic Theses and Dissertations

Staphylococcus aureus is commonly found as normal flora on human skin. As such, it is a frequent cause of skin and soft tissue infection that often spreads to deeper tissue. It has become an especially important microorganism in both clinical and community settings due to its propensity to acquire resistance to antibiotics as well as the invasive mechanisms it utilizes. Specifically, community-associated methicillin resistant Staphylococcus aureus (CA-MRSA) strains have developed resistance to beta-lactam antibiotics and, perhaps more importantly, many invasive pathogenic mechanisms. Thisdissertation explores novel virulence mechanisms of CA-MRSA infections through characterization of novel protein within the prevalent CA-MRSA strain, …

Digitizing Brandenburg: Common Law Drift Toward A Causal Theory Of Imminence, J. Remy Green

Faculty Scholarship

The Supreme Court’s Brandenburg v. Ohio test provides an exception to the First Amendment’s broad guarantee of freedom of speech. Where speech is (1) directed to inciting or producing imminent lawless action, and (2) is likely to incite or produce such action, the First Amendment withdraws its promise of protection. Thus, where the “imminence” of lawless action cannot be shown, free speech cannot be restricted. Since Brandenburg, Courts have applied a test for imminence that turns on proximity in space and in time — that is, the test evaluates how spatiotemporally imminent lawless activity is. In this Article, I argue …

The Global Preclinical Antibacterial Pipeline, Ursula Theuretzbacher, Kevin Outterson, Aleks Engel, Anders Karlén

Use Of Single Irbs For Multi-Site Studies: A Case Report And Commentary From A National Drug Abuse Treatment Clinical Trials Network Study, Ceilidh Nichols, Lynn E. Kunkel, Robin Baker, Eve Jelstrom, Megan Addis, Kim Hoffman, Dennis Mccarty, P. Todd Korthuis

OHSU-PSU School of Public Health Faculty Publications and Presentations

Recent NIH policy stipulates that multi-site studies must use a single or IRB (Institutional Review Board) in order to streamline the review process while maintaining standards for human subjects protection. The Western States Node of the Clinical Trials Network (CTN) used a single IRB for protocol CTN-0067, a clinical trial testing the use of an opioid antagonist (extended-release naltrexone) versus opioid agonists (buprenorphine or methadone) for opioid use disorders among individuals living with HIV. This case study discusses the processes and challenges associated with use of a single IRB. These lessons are also informed by other single IRB experiences within …

Adverse Childhood Experiences, Neuroadaptation, And Resilience: Does Trauma Focused Cognitive Behavioral Therapy Go Far Enough?, Tracie Abbott

Graduate School of Professional Psychology: Doctoral Papers and Masters Projects

Adverse childhood experiences (ACEs) pose a significant public health risk. Current literature suggests ACEs have the potential to significantly disrupt sensitive periods of neurodevelopment. These neuroadaptations can result in social, emotional, and cognitive impairments that place a child at a significantly greater risk for adopting health risk behaviors and lifestyle factors that lead to the major causes of disease, disability, social problems, and early death in adults. Mental health clinicians have a unique opportunity to intervene by working with families to alter the trajectories of the child’s health risk behaviors and lifestyle factors. Trauma Focused Cognitive Behavioral Therapy (TF-CBT), a …

Was Yosef On The Spectrum? Understanding Joseph Through Torah, Midrash, And Classical Jewish Sources (Introduction), Samuel J. Levine

Scholarly Works

The story of Yosef (Joseph) presents some of the most challenging questions of all biblical narratives. Yosef’s behavior, interpersonal relationships, and personal journey and development are often difficult to understand, and at times seem to defy explanation. Leading commentators are repeatedly puzzled both by Yosef’s actions and by the events that surround him. This book attempts to achieve a coherent and cohesive reading of the story that offers a plausible understanding of Yosef’s behaviors toward others and those of others toward him, while at the same time accounting for both his successes and his failures. Toward that goal, the book …

The Constitution As Poetry, Samuel J. Levine

Scholarly Works

Building upon a body of scholarship that compares constitutional interpretation to biblical and literary interpretation, and relying on an insight from a prominent nineteenth century rabbinic scholar, this Article briefly explores similarities in the interpretation of the Torah—the text of the Five Books of Moses—and the United States Constitution. Specifically, this Article draws upon Rabbi Naftali Zvi Yehudah Berlin’s (“Netziv”) intriguing suggestion that the interpretation of the text of the Torah parallels the interpretation of poetry. According to Netziv, this parallel accounts for the practice of interpreting the Torah expansively in ways that derive substantive legal rules and principles far …

Disciplinary Regulation Of Prosecutorial Discretion: What Would A Rule Look Like?, Samuel J. Levine

Scholarly Works

This Essay is the third part of a larger project examining the potential role of professional discipline in the regulation and supervision of prosecutors’ charging decisions. The first two parts of the project argued that courts have both the authority and the ability to exercise effective disciplinary review of charging decisions through the adoption of ethics rules and their enforcement in the disciplinary process. This Essay takes the next step in the project, considering the nature of rules that courts might adopt, by exploring potential rules targeting two improprieties: arbitrary and capricious charging decisions, and discriminatory charging decisions.

Advanced Artificial Intelligence And Contract, John Linarelli

Scholarly Works

The aim of this article is to inquire whether contract law can operate in a state of affairs in which artificial general intelligence (AGI) exists and has the cognitive abilities to interact with humans to exchange promises or otherwise engage in the sorts of exchanges typically governed by contract law. AGI is a long way off but its emergence may be sudden and come in the lifetimes of some people alive today. How might contract law adapt to a situation in which at least one of the contract parties could, from the standpoint of capacity to engage in promising and …

Relationships And Ethics In The Land Use Game, Patricia E. Salkin, Thomas Brown, Aisha Scholes

Scholarly Works

Ethical considerations in the land use decision making process can be organized into a number of categories, including, first and foremost, the broad subject of conflicts of interest.1 Players in the land use game can find themselves in real or perceived conflicts situations based on personal financial interests resulting from investments, including businesses and real estate holdings (such as the location of their property vis-à-vis the location of the subject property before the Board), employment for themselves or members of their immediate family, and memberships in nonprofit organizations that may be either passive or active (e.g., simply dues paying member …

Foreword To Latcrit 2017 Symposium: What’S Next? Resistance Resilience And Community In The Trump Era, Jorge R. Roig, Saru M. Matambanadzo, Sheila I. Vélez-Martínez

Scholarly Works

In this Foreword, we strive to contextualize “LatCrit XXI: What’s Next?” against the backdrop of two crises: the current political crisis in the United States and the continuing crisis of scarcity that impacts the legal academy. Through an examination of these crises, we will reveal how LatCrit scholars, in their efforts to build community and in their commitment to critical outsider scholarship, are part of the constellations of resistance that struggle against el mundo malo. We will argue that LatCrit has become a necessary institution for those seeking to engage in persistent resistance and dissent in the critical and progressive …

Redefining The Reasonable Person In Police Encounters: The Impact Of The Mainstream News Media’S Portrayal Of Modern Police Conduct, Taurus Myhand

Scholarly Works

Who is the “reasonable person”? There is little doubt that every competent legal professional, both in law practice and in the academic setting, has spent a great deal of time attempting to define the reasonable person. “Reasonableness is largely a matter of common sense.” In police encounters, the definition is certainly important to the outcome of questionable police conduct. How the reasonable person is defined often determines whether a police officer has infringed on an individual’s Fourth Amendment guarantee to be secure in their person against unreasonable searches and seizures. As the narratives of the news media shape how some …

Revisionist History? Responding To Gun Violence Under Historical Limitations, Michael Ulrich

Faculty Scholarship

In the D.C. Circuit case Heller v. District of Columbia (Heller II), Judge Kavanaugh wrote that “Heller and McDonald leave little doubt that courts are to assess gun bans and regulations based on text, history, and tradition, not by a balancing test such as strict or intermediate scrutiny.” Now Justice Kavanaugh, will he find support on the highest court for what was then a dissenting view? Chief Justice Roberts, during oral arguments for Heller I, asked “Isn’t it enough to…look at the various regulations that were available at the time…and determine how these—how this restriction and the scope of this …

Digital Platforms And Antitrust Law, Keith N. Hylton

Faculty Scholarship

This Article is about "big data" and antitrust law. Big data, for my purposes, refers to digital platforms that enable the discovery and sharing of information by consumers, and the harvesting and analysis of consumer data by the platform. The obvious example of such a platform is Google. The big platforms owe their market dominance not to anticompetitive conduct, but to economies of scale. This Article discusses three types of anticompetitive conduct associated with digital platforms: kill zone expropriation, acquisition of nascent rivals, and denial of access to data. There is nothing so unusual about digital platforms that would require …
