Mindfulness And Modification Therapy (Mmt) Group Feasibility And Acceptability Among Prison Residents With Dysregulated Behaviors, Leslie Unger

Theses and Dissertations

Mindfulness and Modification Therapy (MMT; Wupperman, 2019) is a transdiagnostic therapy that systematically integrates aspects of six empirically supported treatments for impulsive and dysregulated behavior. As such, MMT may offer an efficient approach to addressing a variety of dysregulated behaviors, thereby supporting increased safety within carceral settings and enhancing goals of rehabilitation. To date, MMT has demonstrated positive results in community settings when treating substance misuse and anger/aggression, but it has not yet been examined in a prison setting. The present research examines the feasibility and acceptability of using a 14-session version of group MMT as a voluntary treatment option …

Pfedrag: A Personalized Federated Retrieval-Augmented Generation System With Depth-Adaptive Tiered Embedding Tuning, Hangyu He, Xin Yuan, Kai Wu, Ren Ping Liu, Wei Ni

Research outputs 2022 to 2026

Large Language Models (LLMs) can undergo hallucinations in specialized domains, and standard Retrieval-Augmented Generation (RAG) often falters due to general-purpose embeddings ill-suited for domain-specific terminology. Though domain-specific fine-tuning enhances retrieval, centralizing data introduces privacy risks. The use of federated learning (FL) can alleviate this to some extent, but faces challenges of data heterogeneity, poor personalization, and expensive training data generation. We propose pFedRAG, a novel Personalized Federated RAG framework, which enables efficient collaborative fine-tuning of embedding models to address these challenges. The key contribution is a new Depth-Adaptive Tiered Embedding (DATE) architecture, which comprises a Global Shared Layer, combined using …

The Dark Side Of International Cooperation: Indifference And The Psychosocial Dynamics Of Cooperative Deterrence, Jamal Barnes

Research outputs 2022 to 2026

States are increasingly resorting to international cooperative agreements to deter migrants and refugees from irregularly arriving at their borders. Although scholars have shown how these cooperative deterrence policies are undermining important refugee and human rights protections, making migration journeys more dangerous, and securitizing and criminalizing people on the move, what has not been adequately examined is how these cooperative arrangements can bring about normative changes that produce indifference to the suffering of refugees and migrants. This article examines the psychosocial dynamics of cooperative deterrence policies to show how the social processes of authorization, routinization, evasion of responsibility, and dehumanization weaken …

Research outputs 2022 to 2026

Central to this phenomenological inquiry is the question of how students’ fundamental needs of belonging, trust and connection are enacted in arts classrooms. Through qualitative semi-structured interviews, this research explores the teaching practices of 23 expert arts teachers in Western Australian schools, revealing strategies to sustain supportive and safe learning environments. The findings highlight the disconnection students face in their schools and the significance of trust in embracing diversity, cultivating quality relationships, and empowering student voice. Understanding these evolving practices can enable less experienced teachers to adapt arts-based approaches to foster inclusive spaces that prioritise student well-being and connection.

Contextualising Hotel Career Behaviour: Testing A Sociocultural And Organizational Career Model, Franklin Akosa, Songshan (Sam) Huang, Hossein Ali Abadi, Jun Wen

Research outputs 2022 to 2026

This study applies Social Cognitive Career Theory (SCCT) to develop and empirically test a contextual model of hotel career outcomes in Ghana, focusing on how social and organizational factors shape employees' career attitudes and intentions. Drawing on survey data from 769 frontline hotel employees, Partial Least Squares Structural Equation Modeling (PLS-SEM) was employed to assess both the measurement and structural models. The results reveal that subjective norms significantly and positively influence career attitudes. Transformational leadership not only strengthens employees' career attitudes and intentions but also moderates the relationship between subjective norms and career attitudes, amplifying their positive effect. Additionally, favourable …

Work Hard, Play Hard, Drink Hard: Frontier Masculinities And Female Teachers’ Experiences In A Regional Australian Mining Town, Kirsten Lambert, Christina Gray, Mary Anne Macdonald, Takei Beard, Kelly Jackson, Sarah Booth

Research outputs 2022 to 2026

Teacher attrition is a significant issue that has been the subject of much recent critical research and public debate. What is less often explored in the literature is the gendered nature of teaching and the unique struggles female teachers face in the workforce, particularly in remote, regional and rural (RRR) schools. As a historically female-dominated profession, women, particularly teacher-mothers face a distinctive set of barriers to career progression in these schools. We apply a critical feminist lens to qualitative data generated from interviews with 21 teachers from 6 different schools in RRR locations in Western Australia. Data reveals a toxic …

Early Outcomes Of A Structured Literacy Implementation Across A School System: The Archdiocese Of Canberra And Goulburn Catalyst Program, Tanya Serry, Jennifer Buckingham, Pamela Snow, Lorraine S. Hammond, Kym Simoncini, Tina Daniel

Research outputs 2022 to 2026

Although professional learning is the main approach for improving teacher knowledge, little evidence exists for its effectiveness in changing practice and improving student outcomes. One possible explanation is poor alignment between professional learning and classroom practice. In this paper, we describe a system-wide approach to changing teacher knowledge and reading pedagogy. Classroom teachers (n = 199) across 43 schools engaged in professional learning on contemporary science of learning and training in the use of published systematic and explicit reading instruction programs. Following the intervention, students’ word reading data revealed that the percentage of students requiring support post intervention had significantly …

Barrett, Moritz Heene, Jörg Henrik Heine, Jack Martin, Lucas B. Mazur, Marek Mcgann, Robert J. Mislevy, Craig Speelman, Aaro Toomela, Ron Weber

Research outputs 2022 to 2026

Psychology's crises (e.g., replicability, generalisability) are currently believed to derive from Questionable Research Practices (QRPs), thus scientific misconduct. Just improving the same practices, however, cannot tackle the root causes of psychology's problems—the Questionable Research Fundamentals (QRFs) of many of its theories, concepts, approaches and methods (e.g., psychometrics), which are grounded in their insufficiently elaborated underlying philosophies of science. Key problems of psychological measurement are critically explored from independent perspectives involving various fields of expertise and lines of research that are well established but still hardly known in mainstream psychology. This comprehensive multi-perspectival review presents diverse philosophies of science that are …
