Community-Based Research: Key Considerations For Researchers And Community Partners When Collaborating, Bothwell Piason, Kathleen A. Fox

The Qualitative Report

Community-based research (CBR) is a research orientation that emphasizes equitable engagement in the process of knowledge production, though researchers and community partners may navigate collaborative partnerships with differing expectations, priorities, and understandings of success. Extant research has demonstrated that successful CBR partnerships can benefit both researchers and community partners, yet little is known about how both groups simultaneously conceptualize successful collaboration across diverse partnership contexts. In this study, we ask: What considerations do researchers and community partners identify as important when engaging in community-based research partnerships? Drawing on semi-structured interviews with 10 university researchers and 10 community partners engaged in …


Autoethnography: Understandings, Evolution, And The Influence Of Genai, Prokopis Christou Aug 2026

Autoethnography: Understandings, Evolution, And The Influence Of Genai, Prokopis Christou

The Qualitative Report

Autoethnography occupies a central place within qualitative research because of its focus on lived experience, reflexivity, and meaning-making. In this paper, I critically examine the implications of generative artificial intelligence (GenAI) for autoethnographic inquiry through a reflexive and theoretically informed discussion situated within the contemporary AI-mediated era. By revisiting key understandings and developments of autoethnography while drawing on technological mediation theory, I explore how GenAI extends beyond a mere tool to become a mediating mechanism capable of profoundly shaping autoethnographic practice. Attention is given to how seemingly minor AI-generated alterations may transform lived experience into more polished, coherent, and emotionally …

The Lived Spirituality Experiences Of Adult Diabetes Patients In Adhering To Treatment, Dwight Mahaputera Marulitua Hutapea

The Qualitative Report

This descriptive phenomenological study explored the lived spirituality experiences of adult patients with Type 2 Diabetes Mellitus (T2DM) in adhering to treatment. Prior research has indicated that spirituality may influence attitudes toward and adherence to chronic disease management; however, empirical evidence addressing the spiritual dimension among people with diabetes remains limited. Guided by Colaizzi's (1978) phenomenological method, in-depth interviews were conducted with 12 purposively selected participants, equally distributed among Christians and Muslims. All interviews were transcribed verbatim and subjected to rigorous phenomenological analysis. Seven themes emerged from the data analysis: (a) spirituality strengthens relationships; (b) spirituality affects choices and outcomes; …


Relational-Developmental Autoethnography: A Method Of Qualitative Inquiry That Fosters Personal Growth, Chris Wells Aug 2026

Relational-Developmental Autoethnography: A Method Of Qualitative Inquiry That Fosters Personal Growth, Chris Wells

The Qualitative Report

This paper introduces relational–developmental autoethnography (RDA), a qualitative method for exploring psychological growth through personal writing and reflection. Developed through lived experience, RDA traces psychological development through sustained, recursive engagement with personal writing. Drawing on an archive of my journals, letters, clinical records, and correspondence spanning more than 30 years, I show how writing and reflection were first tools for my survival, and later became catalysts for insight, healing, and transformation. RDA is grounded in two developmental frameworks: Dąbrowski’s theory of positive disintegration, which views emotional intensity and inner conflict as signs of developmental potential, and relational-cultural theory, which …

Women In The Criminal Justice Pipeline: Perspectives From Policy To Practice, Laila Riaz Aug 2026

Women In The Criminal Justice Pipeline: Perspectives From Policy To Practice, Laila Riaz

Student Theses

The study of the criminal justice system has historically been shaped by a male-centered perspective. Consequently, this has marginalized the unique experiences and challenges faced by women. Women are disproportionately affected by issues such as trauma, caregiving responsibilities, and systemic inequalities, shaping their interactions with the criminal justice system in ways that differ from men. This study examines how women experience the pipeline of the criminal justice system. The “pipeline” refers to the stages of the criminal justice system, ranging from an initial encounter with law enforcement to prosecution, incarceration, and eventual reentry into society. Drawing on interviews with academics …

Linguistic information and its confidence degree are considered simultaneously in such a controller. The temperature and pressure values are taken as input variables, while the throttle rotation is selected as the controller output variable. At first, the Z-number representation system is constructed to include the credibility of linguistic measurements and control rules. Then, a Mamdani Type-1 …


Nonlinear System Identification Based On Fuzzy Radial Basis Neural Network With Multi-Connected Weight Connections, Kabul Khudaybergenov Aug 2026

Nonlinear System Identification Based On Fuzzy Radial Basis Neural Network With Multi-Connected Weight Connections, Kabul Khudaybergenov

Chemical Technology, Control and Management

This paper builds on our earlier radial basis function network with multiple connections (RBFMC) by placing it within a fuzzy inference framework for nonlinear system identification. The idea is inspired by the diversity of neurotransmitters found in biological neurons: instead of a single hidden-to-output weight, RBFMC gives each hidden unit a multi-dimensional connection whose components act as independent filters. Once fuzzy logic is added, each hidden neuron becomes a fuzzy rule, and its antecedent is built from several Gaussian membership functions, one per connection. The resulting Fuzzy RBFMC produces an interpretable, multi-filter description of local regions of the input space …
