Performance Evaluation Of Controllers Using Fuzzy Delphi And Ahp Techniques, Kamala. R. Aliyeva, Nihad Mehdiyev, Shamil Mehdi Aug 2026

Performance Evaluation Of Controllers Using Fuzzy Delphi And Ahp Techniques, Kamala. R. Aliyeva, Nihad Mehdiyev, Shamil Mehdi

Chemical Technology, Control and Management

This study introduces an enhanced decision-support framework that integrates the Fuzzy Delphi method with the Analytic Hierarchy Process (AHP) to improve controller tuning and performance evaluation in uncertain environments. Traditional tuning techniques typically depend on crisp expert judgments and deterministic performance indices; however, industrial control systems are characterized by nonlinear behaviors, uncertain parameter variations, and subjective expert evaluations that are often vague or inconsistent. The Fuzzy Delphi procedure is applied to systematically gather, filter, and consolidate expert insights, enabling a refined set of performance criteria such as stability margins, robustness to disturbances, settling time, overshoot, control effort, and energy consumption …

Malocclusion is a prevalent oral health problem in children associated with oral bad habits, yet the extent to which parental and child knowledge, attitudes, and practices (KAP) influence orthodontic status remains insufficiently understood. This cross-sectional study investigated relationships between parental and child KAP, oral habits, and malocclusion in school-aged children, involving 67 child–parent pairs from an elementary school in Surabaya, Indonesia. Parental and child KAP as well as child-reported oral habits were assessed using a validated questionnaire. Children subsequently underwent standardized clinical orthodontic examinations, including alginate jaw impressions to produce dental study models, which were evaluated using the Index of …

Provincial Disparities In Adolescent Fertility In Indonesia: An Ecological Analysis Of Child Marriage, Median Age At First Marriage, And Family Development Index, Andi Nisa Fathimiyah Afidah, Milla Herdayati

Kesmas

Adolescent fertility remains a public health concern in Indonesia, with substantial variations across provinces. However, the evidence explaining provincial disparities using population-level indicators remains limited. This study aimed to examine provincial disparities in adolescent fertility and assess the association of child marriage, median age at first marriage among women, and the Family Development Index called iBangga with adolescent fertility across Indonesia. This ecological, cross-sectional study used aggregated data from 34 Indonesian provinces. Descriptive statistics, spatial visualization, Pearson’s correlation, and multiple linear regression analyses were performed. The mean adolescent fertility rate was 25.0 births per 1,000 female adolescents aged 15–19 years, …

Early-life nutrition is a critical predictor of long-term health, yet the association between rapid early-childhood growth and adolescent obesity, particularly in relation to the “double burden of malnutrition,” remains under-researched in Indonesia. This study aimed to analyze the association between rapid growth and adolescent obesity. Data were obtained from the 1997, 2000, and 2014 waves of the Indonesian Family Life Survey (IFLS). This study included 641 children (aged 0–23 months at baseline) with complete anthropometric measurements across all three waves. Rapid growth was defined as an increase in z-scores of >0.67 in weight-for-age (WAZ), height-for-age (HAZ), or weight-for-height (WHZ) between …

Diabetes mellitus is a leading cause of mortality and economic burden, with significant impacts on health outcomes and quality of life. Effective self-management is crucial for controlling Type 2 Diabetes Mellitus (T2DM). Thailand has implemented diverse self-management interventions for adults with T2DM in primary care and community settings, but the components, delivery, duration, and outcomes of these interventions have not been synthesized. Following the Arksey and O’Malley framework, Joanna Briggs Institute guidance, and PRISMA-ScR, five databases were searched from inception to June 2025. Eligible English-language intervention studies involved Thai adults with T2DM in primary care or community settings. Study characteristics …

Unveiling Racism: A Systematic Review Of Racism Survey Measures In Education, Wendy Castillo, Juan Cruz, Rachel Renbarger, Christen Priddie, Brein Mosely, Sasha Mejia-Bradford Aug 2026

Unveiling Racism: A Systematic Review Of Racism Survey Measures In Education, Wendy Castillo, Juan Cruz, Rachel Renbarger, Christen Priddie, Brein Mosely, Sasha Mejia-Bradford

Department of Psychology Faculty Scholarship and Creative Works

Education policy research aimed at eliminating racism necessitates methodological innovation that fosters both racial equity–centered approaches and robust empirical analysis of the systemic and structural nature of racism. Most quantitative research in educational psychology does not account for racism in its modeling, thereby obscuring the racialized environments in which students learn (DeCuir-Gunby & Schutz, 2014; Strunk & Andrzejewski, 2023). Drawing from Bronfenbrenner’s ecological systems theory and the ethos of QuantCrit, this study evaluates various scales to highlight gaps and challenges in measuring racism within school settings. This review aims to uplift measures for researchers to use in their work and …

Bridge Simulator Study To Determine The Stopping Distance Of A Large Container Vessel, By Using Anchors, Perera Harindra, K. D. A. P. Sedrick, W. A. N. S. Perera, W. B. C. T. Karunasena

Journal of Innovation in Science, Engineering and Technology

In March 2024, the large containership ``Dali'' suffered a blackout and complete loss of propulsion and steering while outbound from the Port of Baltimore, USA. The vessel was proceeding at about 9 knots in the critical approach channel to the Francis Scott Key Bridge and subsequently allided with the bridge support [\citealpbib6]. As ship sizes continue to increase while channels and bridges remain largely unchanged, understanding realistic emergency maneuvering and stopping capabilities in confined waters has become increasingly important [\citealpbib1].

With Students, As A Student: Using Reflexive Autoethnography To Make Sense Of Navigating Student–Researcher Liminality In A Ph.D., Melody Bishop Aug 2026

With Students, As A Student: Using Reflexive Autoethnography To Make Sense Of Navigating Student–Researcher Liminality In A Ph.D., Melody Bishop

The Qualitative Report

Postgraduate researchers (PGRs) are increasingly encouraged to practice reflexivity. But there is a lack of PGR-authored literature about what it means to negotiate multiple identities, particularly for student–researchers doing research with students. This paper explores challenges experienced during a longitudinal Ph.D. project involving undergraduate students with long-term health conditions. I present outcomes of a reflexive autoethnographic analysis of a diary kept making sense of research challenges, including holding dual positions as a student–researcher at the same institution. Drawing on the notion of liminality, I argue that the boundaries between my student–researcher identities, and between myself and participants, have been consistently …

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 …
