Optimal Pilot Length For Key Generation In Correlated Wireless Channels, Danqi Li, Shihao Yan, Jia Zhang, Jiande Sun, Feng Shu

Research outputs 2022 to 2026

This work examines the optimal pilot length for key generation in correlated wireless channels. We first deduce the secret key capacity as a function of the pilot length N and other system parameters. Then, derive two fixed-point equations to identify the optimal N with and without an eavesdropper. Our analysis and numerical results confirm the existence of the optimal N that maximizes the secret key capacity, and both results for optimal N are consistent. Furthermore, the optimal N generally decreases with average signal-to-noise ratio and maximum Doppler shift. Our examination can provide useful guidelines in designing practical key generation systems.

People who experience a stroke are at a higher risk of recurrent stroke when compared with people who have not had a stroke. Addressing modifiable risk factors like physical inactivity and poor diet has been shown to improve blood pressure, a leading contributor to stroke. However, survivors of stroke often experience challenges with accessing risk reduction services including long wait lists, difficulty with transportation, fatigue, impaired function, and diminished exercise capacity. Providing health interventions via a website can extend the reach when compared with programs that are only offered face to face or via real-time telehealth. Given global challenges of …

Towards An Indigenous-Informed Multispecies Collaboratory, Sandra Wooltorton, Peta J. White

Research outputs 2022 to 2026

How does Australia's latest Indigenous defeat relate to Environmental Education? The answer is direct complicity. This paper begins with the premise that the failure of Australia's 2023 referendum on "The Voice to Parliament"is directly connected with education. The chapter builds on the proposition that local and Indigenous public knowledge could - and should - be the heart of environmental education. We apply a post-qualitative practice that is underpinned by innovative feminisms and the post-qualitative methods within a Multispecies Collaboratory, an experimental way of transforming our learning by attending to the responsive, relational world of all beings. We use this practice …

Parent Implementation Of A Treatment For Late Talkers Based On Cross-Situational Statistical Learning Principles: Treatment Fidelity And Acceptability, Suzanne J. Meldrum, Jennifer Fisk, Jennifer Stopher, Emily F. Hunt

Research outputs 2022 to 2026

Purpose:

Early intervention based on principles of cross-situational statistical learning (CSSL) for late-talking children has shown promise. This study explored whether parents could be trained to deliver this intervention protocol with fidelity and if they found the intervention to be acceptable.

Method:

Mothers of four English-speaking children aged 18–30 months who scored < 10th centile for expressive vocabulary were recruited to an 8-week group training program. Parents were taught principles of CSSL and asked to perform 16 home treatment sessions (30 minutes each) in total, providing auditory bombardment of target words in full sentences at high dose number and syntactic variability, using a range of physical exemplars. Home diaries and two videotaped sessions measured treatment fidelity. Pre- and post-treatment questionnaires measured acceptability. Result: One parent discontinued the study after the second group training session. Three parents completed 15/16 group training sessions and reported completing 87% of home sessions. Two parents demonstrated implementing the intervention as per the target dose number by the first fidelity session (Weeks 2/3), and the third parent was very close to meeting target dose number by the second fidelity session (Weeks 7/8).

Conclusion:

Parents can be trained to deliver an intervention based on cross-situational statistical learning principles.

The Heroic Character, The Neo-Liberal Productive Citizen, And The Feminist Filmmaker, Catherine Gough-Brady

Research outputs 2022 to 2026

I recut an observational documentary about a woman called Bekti into a more conventional hero’s journey for a broadcaster. The hero’s journey narrative requires large obstacles to be overcome by the hero in their search for their ego. In this documentary the obstacle is connecting experimental science with communities with the aim to reduce dengue fever, and the hero’s ‘ego’ is to be an effective communicator. Using the hero’s journey style of narrative reduced the importance of the domestic aspects of Bekti’s life because these scenes did not contribute to overcoming obstacles or finding ego. To explore these changes use …

Cyberbullying Text Identification: A Deep Learning And Transformer-Based Language Modeling Approach, Khalid Saifullah, Muhammad Ibrahim Khan, Suhaima Jamal, Iqbal H. Sarker

Research outputs 2022 to 2026

In the contemporary digital age, social media platforms like Facebook, Twitter, and YouTube serve as vital channels for individuals to express ideas and connect with others. Despite fostering increased connectivity, these platforms have inadvertently given rise to negative behaviors, particularly cyberbullying. While extensive research has been conducted on high-resource languages such as English, there is a notable scarcity of resources for low-resource languages like Bengali, Arabic, Tamil, etc., particularly in terms of language modeling. This study addresses this gap by developing a cyberbullying text identification system called BullyFilterNeT tailored for social media texts, considering Bengali as a test case. The …

Research outputs 2022 to 2026

By offering a delightful experience, role-playing games (RPGs) have attracted many players. However, their development has been challenged by issues such as the emergence of online/mobile games and the proliferation of pirate copies. Therefore, RPG developers should consider different strategies to sustain the RPG series. We conducted a case study on “Chinese Paladin,” an RPG series that has been successful for over two decades in the Greater China region. We identified four strategies for an RPG to sustain itself and develop into a brand, namely (1) timeline-moving strategy, (2) crossover strategy, (3) sublimation strategy, and (4) cross-media strategy. We also …

Assessing The Impact Of Geochemical Mechanism And Interpolation Factor Selection On The Precision Of Low-Salinity Waterflooding Modelling: A Comparative Study, Malek Jalilian, Sedigheh Mahdavi, Peyman Pourafshary, Zheinjiang You, Amir H. Mohammadi

Research outputs 2022 to 2026

The efficacy of low salinity waterflooding (LSWF) as an enhanced oil recovery (EOR) method in carbonate formations has been well established; however, its geochemical modelling in such reservoirs remains insufficiently explored. This study aims to bridge this gap by conducting a comparative analysis of three well-recognised geochemical mechanisms including fines migration, rock dissolution/precipitation, and multi-ion exchange (MIE). Our research encompasses two parts: experimental and modelling. First, we conducted four coreflooding experiments to study the effect of LSWF on oil recovery in core scale as well as on rock wettability by measuring the contact angle of the crude oil-brine-rock system.

Cerebral amyloid angiopathy (CAA) is a type of cerebrovascular disorder characterised by the accumulation of amyloid within the leptomeninges and small/medium-sized cerebral blood vessels. Typically, cerebral haemorrhages are one of the first clinical manifestations of CAA, posing a considerable challenge to the timely diagnosis of CAA as the bleedings only occur during the later disease stages. Fluid biomarkers may change prior to imaging biomarkers, and therefore, they could be the future of CAA diagnosis. Additionally, they can be used as primary outcome markers in prospective clinical trials. Among fluid biomarkers, blood-based biomarkers offer a distinct advantage over cerebrospinal fluid biomarkers …

Sandstone Wettability And Mixed Gas Composition: Unraveling The Impact Of Co2 In Hydrogen Geo-Storage, Zoha D. Isfehani, Amirmansour J. Jafari, Jalal Fahimpour, Mirhasan Hosseini, Stefan Iglauer, Alireza Keshavarz

Research outputs 2022 to 2026

Underground hydrogen storage (UHS) is gaining interest as a secure, long-term solution for storing hydrogen in porous geological formations. In UHS, a cushion gas like CO2 is crucial to maintain the reservoir pressure and optimize recovery. The concept of wettability plays a fundamental role in determining the system's multi-phase displacement characteristics in the porous media. However, there is a gap in the existing literature regarding the wettability of sandstone rocks under geo-storage conditions when H2 and CO2 are injected as the bulk and cushion gases, respectively. To address this gap, we conducted a study investigating the wettability hysteresis phenomenon by …

Crigna, Cristina Daniele, Carsten Sticht, Maike Cueppers, Mark A. Kluth, Christoph Ganss, Markus H. Frank, Norbert Gretz, Karen Bieback

Research outputs 2022 to 2026

Acute kidney injury (AKI) is characterized by a rapid reduction in renal function and glomerular filtration rate (GFR). The broadly used anti-cancer chemotherapeutic agent cisplatin often induces AKI as an adverse drug side effect. Therapies targeted at the reversal of AKI and its potential progression to chronic kidney disease or end-stage renal disease are currently insufficiently effective. Mesenchymal stromal cells (MSCs) possess diverse immunomodulatory properties that confer upon them significant therapeutic potential for the treatment of diverse inflammatory disorders. Human dermal MSCs expressing ATP-Binding Cassette member B5 (ABCB5) have shown therapeutic efficacy in clinical trials in chronic skin wounds or …

An Ecosystem Of Knowledge: Relationality As A Framework For Teachers To Infuse Indigenous Perspectives In Curriculum, Maryanne Macdonald, Sarah Booth, Libby Jackson-Barrett

Research outputs 2022 to 2026

New data is presented from two studies involving thirteen practising secondary teachers and twelve pre-service early childhood, primary and secondary teachers in Australia. The first study explored how non-Indigenous practising teacher identities, shaped by external and policy discourse, create obstacles to teachers’ willingness and confidence in infusing Indigenous perspectives in curriculum. With this knowledge in hand, the researchers utilised a Design-Based Research methodology to conduct a second study with pre-service (ITE) teachers, exploring the power of relationality as a framework to re-shape non-Indigenous pre-service teachers’ conceptualisation of racial and place-based identity. By enabling non-Indigenous pre-service teachers to construct an authentic …

Aboriginal Students’ Journeys To University – Privileging Our Sovereign Voices, Renae Isaacs-Guthridge

Research outputs 2022 to 2026

Since invasion the trajectory of colonial education in Australia has been linear; most students are expected to complete primary and secondary education, and, if accepted, seamlessly transition to university by 18 years of age. The reality is that many students do not experience continuity in their education, let alone reach university, and this can be particularly problematic for Aboriginal and Torres Strait Islander students (Australian Institute of Health and Welfare, 2024; Productivity Commission, 2024). Put simply, Australia’s education system continues to fail many Aboriginal and Torres Strait Islander students, further silencing our sovereign voices. Drawing on an Indigenist research paradigm …

Developing An 'Eportfolio Of Evidence' Towards Employment And Registration For Early Childhood Teachers, Pauline Roberts, Leonie Menzel, Bev Adkin, Lennie Barblett

Research outputs 2022 to 2026

ePortfolios have been in use in Initial Teacher Education (ITE) courses for many years. The link to employability has been part of these initiatives, however, recent concerns over workforce and employment requires additional focus to ensure the ongoing sustainability of the ePortfolio. Ensuring teachers are 'classroom ready' led to increased pressure on pre-service teachers (PSTs) to demonstrate achievement of the Australian Professional Standards for Teachers (APST) (Australian Institute for Teaching and School Leadership, 2017). The goal of this project was to explore and influence PST's thinking towards the ePortfolio through changes in practice. The research entailed a rapid systematic review …

Inequitable Organ Allocation, Benjamin Mcmichael

Articles

Seventeen people die every day in the United States waiting for an organ transplant, and over 100,000 people are currently on waitlists to receive a donated organ. Given these stark numbers, the allocation policies governing who receives donated organs are both critically important and hotly debated. Congress passed the National Organ Transplant Act in 1984 with the goal of eliminating markets for organs and the promise of equitable access to transplants without regard to geography or socioeconomic status. Despite these laudable goals, recent developments in organ allocation policy have led to multiple lawsuits, congressional inquiries, and an expose in the …

Black college students continue to face the specter of anti-Blackness which creates additional barriers to success and flourishing in higher education. This study investigates how instructors in higher education can provide racial equity to Black students in AANAPISI/HSI classrooms through counterspaces. We use culturally relevant pedagogy to investigate the experiences of 21 Black college students at an AANAPISI/HSI to understand better how higher education instructors can utilize counterspaces, places where Black college students can challenge dominant discourses and create a collegial learning environment. We identified three counterspace themes: (1) Mitigate Eurocentric Pedagogy, (2) Employ Black and Critical Scholarship, and (3) …

Post-Truth's Effect On The Brain And The Future Self: A Critical Communication Pedagogy Response, David H. Kahl Jr.

Journal of Communication Pedagogy

The university was created for the critical examination of ideas to seek truth. However, the proliferation of post-truth messages has made this goal more difficult to reach, creating an important communication pedagogy problem. Hegemonic forces create post-truth messages to mislead people and play to their existing beliefs in order to maintain and advance power. Post-truth messages are particularly effective because they cause cognitive overload and temporal discounting. Critical communication pedagogy (CCP) is a means by which instructors and students can evaluate post-truth messages. CCP allows for dialogue to reduce the cognitive issues that post-truth messages cause and allow for the …

Engaging Impasse: Nurturing A Culture Of Dialogic Engagement On A University Campus, Patricia Ann Hawk

Journal of Communication Pedagogy

Universities have historically fostered spaces where students, faculty, staff, and administration can fruitfully engage in discussion around contentious issues. Current political divisions have had a chilling effect on these discussions inside and outside the classroom. To nurture a campus culture of dialogic engagement, the communication studies department in collaboration with the DEI office began a campus dialogue project that invited faculty, staff, students, and administration to participate in monthly dialogues focused on cultural impasse topics. This 5-year project has demonstrated that university communication studies departments can be instrumental in helping community members cross organizational boundaries to engage in challenging dialogues …

#Politicalcommunicationsowhite: A Call For Considering Race In The Undergraduate Political Communication Course, Ant Woodall, Lindsey Meeks

Journal of Communication Pedagogy

The field of communication has been working to reconcile its historic omission of race from research and pedagogy. The subfield of political communication has begun this process in its research but has yet to consider the implications of race missing from pedagogy. This essay offers an argument for including race in the political communication course, in the form of more focus on race in course content and more work by scholars of color. We offer reasons for these inclusions, ways for instructors to begin this incorporation, and what considerations instructors must be mindful of throughout the process.

Development Of A Measure Assessing Adolescent Aggression: The Aggressive Behavior Risk Assessment- Adolescent- Parent Report (Abra-A-Pr), Katherine Fallon

College of Graduate Studies: Theses & Dissertations

Although parent-report scales for general behavioral difficulties and aggression (e.g., verbal and physical aggression) exist, there are currently no measures assessing sexual behaviors in this context. Commonly, parent-report measures provide a few items relevant to behavioral aggression, and items encompassing sexually aggressive behaviors are frequently vague and non-specific in the actions being committed by the adolescent. The primary purpose of this project was to develop a comprehensive and multifaceted parent-report measure for aggressive behavior in adolescents. Three separate studies were conducted to evaluate the psychometric properties of the measure. Exploratory (EFA) and confirmatory factor analysis (CFA) were used to investigate …
