Background: Most assessments in health professions education consist of knowledge-based examinations as well as practical and clinical examinations. Among the most challenging aspects of clinical assessments is decision making related to borderline grades assigned by examiners. Borderline grades are commonly used by examiners when they do not have sufficient information to make clear pass/fail decisions. The interpretation of these borderline grades is rarely discussed in the literature. This study reports the application of the Objective Borderline Method (version 2, henceforth: OBM2) to a high stakes Objective Structured Clinical Examination undertaken at the end of the final year of a ...

Faculty of Science, Medicine and Health - Papers: part A

Ceratodon purpureus is a cosmopolitan moss that survives some of the harshest places on Earth: from frozen Antarctica to hot South Australian deserts. In a study on the survival mechanisms of the species, nine compounds were isolated from Australian and Antarctic C. purpureus. This included five biflavonoids, with complete structural elucidation of 1 and 2 reported here for the first time, as well as an additional four known phenolic compounds. Dispersion-corrected DFT calculations suggested a rotational barrier, leading to atropisomerism, resulting in the presence of diastereomers for compound 2. All isolates absorbed strongly in the ultraviolet (UV) spectrum, e.g ...


Nonlinear Analysis Of Circular High Strength Concrete-Filled Stainless Steel Tubular Slender Beam-Columns, Vipulkumar I. Patel, Qing Quan Liang, Muhammad N. S Hadi Jan 2017

Nonlinear Analysis Of Circular High Strength Concrete-Filled Stainless Steel Tubular Slender Beam-Columns, Vipulkumar I. Patel, Qing Quan Liang, Muhammad N. S Hadi

Faculty of Engineering and Information Sciences - Papers: Part A

Concrete-filled stainless steel tubular (CFSST) slender columns are increasingly used in composite structures owing to their distinguished features, such as aesthetic appearance, high corrosion resistance, high durability and ease of maintenance. Currently, however, there is a lack of an accurate and efficient numerical model that can be utilized to determine the performance of circular CFSST slender columns. This paper describes a nonlinear fiber-based model proposed for computing the deflection and axial load-moment strength interaction responses of eccentrically loaded circular high-strength CFSST slender columns. The fiber-based model incorporates the accurate three-stage stress-strain relations of stainless steels, accounting for different strain hardening ...

Hybrid Structure Of White Layer In High Carbon Steel - Formation Mechanism And Its Properties, Rumana Hossain, Farshid Pahlevani, Evelien Witteveen, Amborish Banerjee, Bill Joe, B Prusty, Rian J. Dippenaar, Veena Sahajwalla

Faculty of Engineering and Information Sciences - Papers: Part B

This study identifies for the first time, the hybrid structure of the white layer in high carbon steel and describes its formation mechanism and properties. The so-called 'white layer' in steel forms during high strain rate deformation and appears featureless under optical microscopy. While many researchers have investigated the formation of the white layer, there has been no definitive study, nor is there sufficient evidence to fully explain the formation, structure and properties of the layer. In this study, the formation, morphology and mechanical properties of the white layer was determined following impact testing, using a combination of optical and ...


Making It: The Role Of School-Based Intervention In Shaping Educational Aspirations Expectations And Achievement Among High School Students, Maeve Williams Jun 2016

Making It: The Role Of School-Based Intervention In Shaping Educational Aspirations Expectations And Achievement Among High School Students, Maeve Williams

Honors Theses

In an age when higher education has become increasingly channeled as a means of gaining access to an information-driven economy, it is important to note who does and does not enroll in postsecondary courses. The American ‘achievement’ ideology touts education as an opportunity equalizer, and attributes lack of achievement in this system to individual failing. An extensive body of literature, however, points to systemic barriers which create a gap in achievement, primarily along the social fault lines of early development and family characteristics, peers and community, school environment and locational setting, and the demographic factors of race, socioeconomic class and ...


The Psychology Of Romantic Relationships, Darby Dietrich Jun 2016

The Psychology Of Romantic Relationships, Darby Dietrich

Honors Theses

Prior research on self-monitoring suggests that high self-monitors are more likely to choose a romantic partner based on status and appearance. Conversely, low self-monitors put a greater emphasis on shared values and interests. In the current research, we examined the self-monitoring differences in both dating relationships and marriages. Participants were given a survey in which they answered personal questions, questions about their past relationships, qualities that are important in potential dating and marriage partners, and the Snyder and Gangestad (1986) 18-item Self-Monitoring scale. Trends were consistent with previous research, such that high self-monitors were more likely to divorce than low ...

High Intrinsic Sensitivity Etched Polymer Fiber Bragg Grating Pair For Simultaneous Strain And Temperature Measurements, Kishore Bhowmik, Gang-Ding Peng, Yanhua Luo, Eliathamby Ambikairajah, Vedran Lovric, William R. Walsh, Ginu Rajan

Faculty of Engineering and Information Sciences - Papers: Part A

A sensing configuration for simultaneous measurement of strain and temperature with enhanced intrinsic sensitivity based on a fiber Bragg grating (FBG) pair with one grating inscribed in the etched and the other in unetched polymer fiber region is demonstrated. A poly (methyl methacrylate) based single-mode polymer fiber is etched to different diameters, and it is observed that etching can lead to change in the material properties of the fiber, such as Young's modulus and thermal expansion coefficient, which can play a vital role in improving its intrinsic sensing capabilities. Thus, exploiting the different strain and temperature sensitivities exhibited by ...


Influence Of Cr-Rich Oxide Scale On Sliding Wear Mechanism Of Ferritic Stainless Steel At High Temperature, Xiawei Cheng, Zhengyi Jiang, Buyung Kosasih, Hui Wu, Suzhen Luo, Laizhu Jiang Jan 2016

Influence Of Cr-Rich Oxide Scale On Sliding Wear Mechanism Of Ferritic Stainless Steel At High Temperature, Xiawei Cheng, Zhengyi Jiang, Buyung Kosasih, Hui Wu, Suzhen Luo, Laizhu Jiang

Faculty of Engineering and Information Sciences - Papers: Part A

The tribological tests of a ferritic stainless steel (FSS) 445 in contact with high-speed steel (HSS) were performed on a high-temperature pin-on-disc tribometer. Wear exhibited significant difference when the FSS 445 was oxidised with a Cr-rich oxide scale on the surface. The HSS pin displayed adhesive wear when there was no oxide scale on the stainless steel disc, and in the early stages, the coefficient of friction fluctuated significantly, but the level of wear changed as Cr2O3 particles formed. The wear was then reduced, and the coefficient of friction remained stable. The Cr-rich oxide scale which formed on the stainless ...


Robustness Of Ipsa Optimized High-Dose-Rate Prostate Brachytherapy Treatment Plans To Catheter Displacements, Joel Poder, May Whitaker Jan 2016

Robustness Of Ipsa Optimized High-Dose-Rate Prostate Brachytherapy Treatment Plans To Catheter Displacements, Joel Poder, May Whitaker

Faculty of Engineering and Information Sciences - Papers: Part A

Purpose: Inverse planning simulated annealing (IPSA) optimized brachytherapy treatment plans are characterized with large isolated dwell times at the first or last dwell position of each catheter. The potential of catheter shifts relative to the target and organs at risk in these plans may lead to a more significant change in delivered dose to the volumes of interest relative to plans with more uniform dwell times. Material and methods: This study aims to determine if the Nucletron Oncentra dwell time deviation constraint (DTDC) parameter can be optimized to improve the robustness of high-dose-rate (HDR) prostate brachytherapy plans to catheter displacements ...

High Temperature Postsynthetic Rearrangement Of Dimethylthiocarbamate-Functionalized Metal-Organic Frameworks, Timothy Ablott, Marc Turzer, Shane Telfer, Christopher Richardson

Faculty of Science, Medicine and Health - Papers: part A

A thermally promoted postsynthetic rearrangement has been performed on a zinc IRMOF-9-type framework bearing dimethylthiocarbamate tag groups. The rearrangement was accomplished via conventional heating at 285 °C. Crucially, despite the high temperature, the MOF maintains its high accessible surface area and pore space following thermal treatment. The structures and physical properties of the frameworks were characterized by a combination of single-crystal X-ray diffraction, powder X-ray diffraction, differential thermal-thermogravimetric analysis, and gas sorption analysis. The rearrangement results in a slightly higher level of CO2 adsorption for the modified MOF but with equivalent heat of adsorption. This work offers new perspectives ...

A Strategy For Configuration Of An Integrated Flexible Sulfur Cathode For High-Performance Lithium-Sulfur Batteries, Hongqiang Wang, Wenchao Zhang, Hua-Kun Liu, Zaiping Guo

Faculty of Engineering and Information Sciences - Papers: Part A

Lithium-sulfur batteries are regarded as promising candidates for energy storage devices owing to their high theoretical energy density. The practical application is hindered, however, by low sulfur utilization and unsatisfactory capacity retention. Herein, we present a strategy for configuration of the sulfur cathode, which is composed of an integrated carbon/sulfur/carbon sandwich structure on polypropylene separator that is produced using the simple doctor-blade technique. The integrated electrode exhibits excellent flexibility and high mechanical strength. The upper and bottom carbon layers of the sandwich-structured electrode not only work as double current collectors, which effectively improve the conductivity of the electrode ...

Titanium aluminides find application in modern light-weight, high-temperature turbines, such as aircraft engines, but suffer from poor plasticity during manufacturing and processing. Huge forging presses enable materials processing in the 10-GPa range, and hence, it is necessary to investigate the phase diagrams of candidate materials under these extreme conditions. Here, we report on an in situ synchrotron X-ray diffraction study in a large-volume press of a modern (α2 + γ) two-phase material, Ti-45Al-7.5Nb-0.25C, under pressures up to 9.6 GPa and temperatures up to 1686 K. At room temperature, the volume response to pressure is accommodated by the transformation ...

The community diversities of two oil reservoirs with low permeability of 1.81 x 10 '3 and 2.29 x 10 '3 1/4m 2 in Changqing, China, were investigated using a high throughput sequencing technique to analyze the influence of biostimulation with a nutrient activator on the bacterial communities. These two blocks differed significantly in salinity (average 17,500 vs 40,900 mg/L). A core simulation test was used to evaluate the effectiveness of indigenous microbial-enhanced oil recovery (MEOR). The results indicated that in the two high salinity oil reservoirs, one reservoir having relatively lower salinity level and ...

Confined Sno2 Quantum-Dot Clusters In Graphene Sheets As High-Performance Anodes For Lithium-Ion Batteries, Chengling Zhu, Shenmin Zhu, Kai Zhang, Zeyu Hui, Hui Pan, Zhixin Chen, Yao Li, Di Zhang, Dawei Wang

Faculty of Engineering and Information Sciences - Papers: Part A

Construction of metal oxide nanoparticles as anodes is of special interest for next-generation lithium-ion batteries. The main challenge lies in their rapid capacity fading caused by the structural degradation and instability of solid-electrolyte interphase (SEI) layer during charge/discharge process. Herein, we address these problems by constructing a novel-structured SnO2-based anode. The novel structure consists of mesoporous clusters of SnO2 quantum dots (SnO2 QDs), which are wrapped with reduced graphene oxide (RGO) sheets. The mesopores inside the clusters provide enough room for the expansion and contraction of SnO2 QDs during charge/discharge process while the ...

The Struggle For Legitimacy: Language Provision In Two 'Residual' Comprehensive High Schools In Australia, Stephen Black, Jan Wright, Kenneth E. Cruickshank

Faculty of Social Sciences - Papers

Despite the contemporary policy rhetoric of global citizenry and the importance of languages and intercultural capabilities, language learning in Australian schools struggles for recognition and support. The curriculum marginalisation of languages, however, is uneven, affecting some school sectors more than others. In this article, we examine the provision of languages in two government comprehensive high schools, both low socio-economic status, located in urban areas in New South Wales, Australia's largest state. They are termed 'residual' high schools because they cater for the students remaining in the local schools while others attend either private or selective government high schools. We ...

Cognitive And Oculomotor Performance In Subjects With Low And High Schizotypy: Implications For Translational Drug Development Studies, Ivan Koychev, D Joyce, Emma Barkus, Ulrich Ettinger, Anne Schmechtig, Colin Dourish, Gerard Dawson, Kevin Craig, John Francis Deakin

Faculty of Social Sciences - Papers

The development of drugs to improve cognition in patients with schizophrenia is a major unmet clinical need. A number of promising compounds failed in recent clinical trials, a pattern linked to poor translation between preclinical and clinical stages of drug development. Seeking proof of efficacy in early Phase 1 studies in surrogate patient populations (for example, high schizotypy individuals where subtle cognitive impairment is present) has been suggested as a strategy to reduce attrition in the later stages of drug development. However, there is little agreement regarding the pattern of distribution of schizotypal features in the general population, creating uncertainty ...

Faculty of Engineering and Information Sciences - Papers: Part B

In this paper, the isothermal oxidation of the indefinite chill (IC) roll is investigated by using a thermogravimetric analyzer (TGA) from 550 to 700 °C under dry and humid atmospheres. It is found that the oxidation kinetics follow a linear trend and the oxide scale consists of two layers after the oxidation in dry air but three layers in humid air above 600 °C. In dry air, the graphite is covered by the oxide scale above 650 °C. The water vapor accelerates the oxidation of the matrix and the graphite. The graphite is covered by the extension of the oxide ...

A High Prevalence Of Malnutrition In Acute Geriatric Patients Predicts Adverse Clinical Outcomes And Mortality Within 12 Months, Karen E. Charlton, Marijka J. Batterham, Steven Bowden, Abhijeet Ghosh, Katherine Caldwell, Lilliana Barone, Michelle Mason, J. Potter, Barbara Meyer, Marianna Milosavljevic

Dr Marijka Batterham

Background & aims Older malnourished patients experience increased length of hospital stay and greater morbidity compared to their well nourished counterparts. This study aimed to assess whether nutritional status at hospital admission predicted clinical outcomes at 12 months follow-up. Methods Secondary data analysis of 2602 consecutive patient admissions to an acute tertiary hospital in New South Wales, Australia on or before 1st June 2009. Twelve-month data was analysed in a sub-sample of 774 patients. Nutritional status was determined within 72 h of admission using the Mini Nutritional Assessment (MNA). Outcomes, obtained from electronic patient records included hospital readmission rate, total length of stay (LOS), change in level of care at discharge, and in-hospital mortality. Results A third (34%) of patients were malnourished and 55% at risk of malnutrition. Using a Cox proportional hazards regression model, controlling for underlying illness and age, patients at risk of malnutrition were 2.46 (95% CI: 1.36, 4.45; p = 0.003) times more likely to have a poor clinical outcome (mortality/discharge to higher level of care), while malnourished patients had a 3.57 (95% CI: 1.94, 6.59; p = 0.000) times higher risk. Conclusions A poor nutritional status carries a substantially greater risk of death and/or loss of dependency in older adults. Interventions to improve the nutritional status of patients during their hospital stay, and following discharge back to the community, are needed to lower the risk of adverse outcomes.

Segregation Of A Latent High Adiposity Phenotype In Families With A History Of Type 2 Diabetes Mellitus Implicates Rare Obesity-Susceptibility Genetic Variants With Large Effects In Diabetes-Related Obesity, Arthur B. Jenkins, Marijka Batterham, Dorit Samocha-Bonet, Katherine Tonks, Jerry R. Greenfield, Lesley V. Campbell

Dr Marijka Batterham

Background We recently reported significantly greater weight gain in non-diabetic healthy subjects with a 1st degree family history (FH+) of type 2 diabetes mellitus (T2DM) than in a matched control group without such history (FH−) during voluntary overfeeding, implying co-inheritance of susceptibilities to T2DM and obesity. We have estimated the extent and mode of inheritance of susceptibility to increased adiposity in FH+. Methods Normoglycaemic participants were categorised either FH+ (≥1 1st degree relative with T2DM, 50F/30M, age 45±14 (SD) yr) or FH− (71F/51M, age 43±14 yr). Log-transformed anthropometric measurements (height, hip and waist circumferences) and lean ...

High Retention Membrane Bioreactors: Challenges And Opportunities, Wenhai Luo, Faisal Ibney Hai, William Price, Wenshan Guo, Hao H. Ngo, Kazuo Yamamoto, Long Nghiem

Faisal I Hai

Extensive research has focussed on the development of novel high retention membrane bioreactor (HR-MBR) systems for wastewater reclamation in recent years. HR-MBR integrates high rejection membrane separation with conventional biological treatment in a single step. High rejection membrane separation processes currently used in HR-MBR applications include nanofiltration, forward osmosis, and membrane distillation. In these HR-MBR systems, organic contaminants can be effectively retained, prolonging their retention time in the bioreactor and thus enhancing their biodegradation. Therefore, HR-MBR can offer a reliable and elegant solution to produce high quality effluent. However, there are several technological challenges associated with the development of HR-MBR ...

The Relationship Between Self-Esteem And Academic Achievement In High Ability Students: Evidence From The Wollongong Youth Study., Wilma Vialle, Patrick C. L. Heaven, Joseph Ciarrochi

joseph Ciarrochi

The relationship between self-esteem and academic achievement is one that is regarded by many educators as a well-established fact. This belief has been often invoked in order to argue against the provision of ability grouping for gifted students. Refuting that commonly-held belief, this research examined the relationship between self-esteem and academic achievement in 65 high-ability secondary students, a sample drawn from a longitudinal study of over 900 students. The research demonstrated that there were no differences in measured selfesteem between the gifted and non-gifted students. More contentiously, though, the research found no correlation between self-esteem and academic achievement for the ...

Help-Seeking Patterns For Suicidal And Non-Suicidal Problems In Two High School Samples, Coralie J. Wilson, Joseph V. Ciarrochi, Debra Rickwood, Frank P. Deane

joseph Ciarrochi

Few distressed young people seek professional psychological help for either personal-emotional problems or suicidal ideation. This paper describes two studies that have examined help-seeking patterns in two contrasting high school populations. Two hundred and sixty four Il1awarra public high school students and 307 Queensland private high school students completed a questionnaire measuring intentions to seek help from a variety of fonnal and informal sources, in addition to no-one for personal-emotional and suicidal problems. Students in both samples indicated they would seek help from different sources of help for different problem types, but friends were rated as the most likely source ...

Does Participation In High School Sports Influence Your Income?, Marisa Lieberman Jun 2015

Does Participation In High School Sports Influence Your Income?, Marisa Lieberman

Honors Theses

My thesis uses data from the National Education Longitudinal Study of 1988 (NELS-88) to examine the relationship between participation in high school athletics and income. NELS-88 follows students from 8th grade through age 25 and asks them questions about family, school, and personal preferences. I use this information to determine if participation in high school sports affects a person’s wage when he or she enters the labor force. Students gain valuable skills from playing on a sports team that help them achieve great things later in life, such as higher paying jobs. However, students who join sports teams may ...


Over-Voltage Mitigation Within Distribution Networks With A High Renewable Distributed Generation Penetration, Joel Kennedy, Philip Ciufo, Ashish Agalgaonkar Apr 2015

Over-Voltage Mitigation Within Distribution Networks With A High Renewable Distributed Generation Penetration, Joel Kennedy, Philip Ciufo, Ashish Agalgaonkar

Dr Philip Ciufo

The rapid growth of grid-connected distributed generation has increased the likelihood of over-voltage occurrences in distribution networks. In recent times, much research has taken place in order to develop a control strategy to mitigate the voltage rise problem. However, most of the published strategies require re-tuning when additional resources are connected, or have a strong dependence on network parameters, such as fault level. This paper proposes a novel over-voltage mitigation scheme that has many advantages not observed in literature. Firstly, the control scheme can integrate with an existing feeder in a plug-and-play fashion. No prior analysis is necessary to configure ...
