Considerations When Exploring One’S Arts-Based Practice As Research, David L. Page Aug 2025

Considerations When Exploring One’S Arts-Based Practice As Research, David L. Page

Imaginings: creative practice and inquiry

This article shares insight into some of the knowledge gained on a higher degree research (HDR) study journey, which I wish I had access to prior to my commencement of that journey. I presented this on 8 July 2025 at the SAE University College Week 7 Forum, and trust this insight may be of interest to those SAE faculty who are new to higher education (HE) research, who have an interest in exploring one’s own arts-based practice as part of the Scholarship and Research activities now being encouraged at SAE University College.

Implementing A Questioning Strategy In Teaching Reading Texts In Efl Classes: A Qualitative Study, Mohammed A. Alzahrani Dr. Aug 2025

Implementing A Questioning Strategy In Teaching Reading Texts In Efl Classes: A Qualitative Study, Mohammed A. Alzahrani Dr.

The Qualitative Report

Developed by Beck and McKeown in the 1980s, Questioning the Author (QtA) emphasises active engagement with texts to construct meaning rather than passive information extraction. Despite numerous studies attempting to solve challenges in the English as a Foreign Language (EFL) context, there is a lack of interpretive studies that investigate this issue from the actual field. This exploratory study investigated how EFL teachers' implementation of QtA and their perspectives toward the use of the QtA strategy in teaching reading comprehension in Saudi secondary schools through nine interviews and eighteen classroom observations, analysed thematically. Findings showed that effective QtA use requires …

"The Cake Is A Lie:" Locating Loot Boxes In Indian Gaming Framework, Aman Gupta, Samriddh Sharma Aug 2025

"The Cake Is A Lie:" Locating Loot Boxes In Indian Gaming Framework, Aman Gupta, Samriddh Sharma

Indian Journal of Law and Technology

Lootboxes have become endemic in modern video games. These microtransactions allow users to purchase virtual containers without knowing their content, which is determined by chance. There have been increasing concerns about the negative impact of loot-box purchases on mental health and whether these amount to gambling under various laws. In response, several countries have started applying existing gambling laws or legislating new measures to regulate lootboxes. This raises questions about the present state of regulations in the Indian context and whether they are adequate in meeting the risks posed by lootboxes. In the present article, the authors explain the concept …

Centring Marginalisation In The Development Of Digital Courts: Reflections From Argentina, India, Kenya, And Malaysia, Siddharth Peter De Souza, Varsha Aithala, Francisco Mignaquy, Mercy Muendo, Anisha Nadkarni

Indian Journal of Law and Technology

This paper presents a multi-jurisdictional analysis of digitalisation of justice and the perceived role of courts as public institutions upholding the rule of law and ensuring access to justice to all. Using selected examples from Argentina, India, Kenya and Malaysia, it examines the impact of digitalisation efforts of these countries on their citizens, marginalised populations, the State and private sector. We propose to design an approach to digital justice that centres people on the margins of digital transformation of courts. This includes three elements – first, engagement with people centered perspectives; second, focus on disadvantage and addressing socio-technical factors; and …


Can Correction Messages Reduce The Spread Of Fake News On Social Media? The Impact Of Information Updates On The Effectiveness Of Corrections, Kelvin K. King, Diego Escobari Aug 2025

Can Correction Messages Reduce The Spread Of Fake News On Social Media? The Impact Of Information Updates On The Effectiveness Of Corrections, Kelvin K. King, Diego Escobari

School of Economics and Finance Faculty Publications

Although government agencies and fact-checking organizations issue correction messages to mitigate misinformation dissemination on social media, their efforts have been largely ineffective. Drawing on Information Manipulation Theory (IMT) and information extracted from over 84 million tweets, we examine the impact of correction messages and explore how different information updates affect their effectiveness. Our empirical approach differentiates between subpopulations of correction messages. The results support the existence of two distinct types: correction messages that significantly mitigate the spread of fake news—a 1 percent increase in “effective” messages decreases the spread of fake news by 0.89 percent; and those that amplify the …

Swahili And English Sell, But What About Iraqw And Sukuma? Tanzanian Native Languages And Ethnic Affiliations In Bottom-Up Commercial Signage, Adventina Buberwa Aug 2025

Swahili And English Sell, But What About Iraqw And Sukuma? Tanzanian Native Languages And Ethnic Affiliations In Bottom-Up Commercial Signage, Adventina Buberwa

Journal of Humanities and Social Sciences

Policy statements in Tanzania forbid the use of ethnic community languages but permits Swahili and English in the public space. In this paper, we question the total absence of ethnic community languages in signposts in which previous studies of linguistic landscape attested the presence of unpermitted languages of Arabic, Chinese and Hindi. Under the auspices of the social identity theory, we envisaged the investigation and analysis of personal and place names on privately-owned commercial signposts. It has come out clearly that owners of the businesses represented would no doubt hope that the names they include in their signage would appeal …

Intelligent Control Of Wind Turbines: A Neural-Fuzzy Controller For Pitch And Yaw Angle Regulation Under Variable Wind Conditions, Salah Ali Daoud, Samir Ali Amin, Salah Sabeeh Abed Al Kareem

Al-Farahidi Expert Systems Journal

By modifying the pitch and yaw angles of the blades, the study presents a hybrid neural-fuzzy controller for wind turbines that enhances performance in variable wind conditions. The suggested system integrates fuzzy logic (for decision-making) and artificial neural networks (for learning), unlike conventional PID and fuzzy PID controllers, which have trouble with nonlinear dynamics. It employs two stages of control: pitch control at high wind speeds and yaw control at low wind speeds. The hybrid controller performs noticeably better than PID-based techniques, according to MATLAB/Simulink simulations, lowering pitch control error by 40%, stabilizing the system in 0.1 seconds instead of …


Belonging: Stories From Multilingual Learners In The Linguistic Minority, Riley Stouffer Aug 2025

Belonging: Stories From Multilingual Learners In The Linguistic Minority, Riley Stouffer

Electronic Theses and Dissertations

This qualitative case study examines how multilingual learners in the linguistic minority (MLLMs) experience connection and belonging in a Rocky Mountain middle school. Although multilingual learners (MLs) have received increased attention, MLLMs, whose home languages are not widely spoken in the school context, remain overlooked. Grounded in Krashen’s (1982) Affective Filter Hypothesis and Wills and Shinar’s (2000) Supportive Functions of Belonging, this study explores how MLLMs navigate school, what fosters or hinders belonging, and how these experiences shape engagement.

Data from semistructured interviews, classroom observations, and field notes with eight MLLM students in grades 6–8 revealed that belonging was fostered …

A Guidance Practice Model: Reframing Prevention, Identification, And Treatment Of Trauma-Impacted Students With Intellectual Disabilities, Mark H. Thomas

Electronic Theses and Dissertations

The experience and exposure of trauma among youth, especially continuous traumatic experiences, poses considerable risks of long-term effects. Moreover, untreated trauma and subsequently negative mental health outcomes, like anxiety and depressive disorders, can negatively impact the psychosocial and academic functioning of students. One population that is generally overlooked regarding mental health in schools are students with intellectual disabilities (ID). This is problematic as this population is at an increased risk of traumatic experiences, such as maltreatment and social exclusion.

Moreover, the comorbidity of trauma and internalizing disorders among students with ID can exacerbate already existing challenges and deficits with social …

Developing Deep Learning Methods For Cognitive Impairment Detection Based On Non-Invasive Data, Muath Alsuhaibani Aug 2025

Developing Deep Learning Methods For Cognitive Impairment Detection Based On Non-Invasive Data, Muath Alsuhaibani

Electronic Theses and Dissertations

Cognitive impairment detection is on the rise to help reduce the burden of healthcare costs on institutions and individuals. Mild Cognitive Impairment (MCI) is an early stage of cognitive decline progressing to Alzheimer’s disease (AD) or AD-related Dementia (ADRD). Detecting the early stages of AD/ADRD is crucial for early interventions among older adults to mitigate cognitive decline over time. However, the current diagnostic methods are often costly and/or invasive, such as MRI and PET scans. Thus, the search for non-invasive and cost-effective screening tools for the early detection of cognitive impairment using speech, language, visual, and motor data is growing. …

Essays On Economic Behaviour, Yiting Guo Aug 2025

Essays On Economic Behaviour, Yiting Guo

Lingnan Theses (MPhil & PhD)

My PhD thesis comprises three studies. The first study examines prosocial behavior; the second analyzes vaccination behavior; and the third investigates communicative behavior in the context of trade. Specifically, the first study investigates the impact of donation visibility on individual prosocial behavior. It develops a sequential-move model based on the prosocial behavior framework proposed by Benabou and Tirole (2006). In Stage 1, individuals decide whether to attend a charity event, and if so, in Stage 2, decide on the amount to donate. In this model, an individual’s decision to engage in prosocial behavior is influenced by three main factors: intrinsic …

Correlating Cross-Service Behavioral Signals To Identify Coordinated Inauthentic Activity, Mithun Kumar S R Aug 2025

Correlating Cross-Service Behavioral Signals To Identify Coordinated Inauthentic Activity, Mithun Kumar S R

Defensive Publications Series

Some systems for detecting fraudulent user-generated content (UGC) can be siloed and reactive, analyzing individual pieces of content or account metrics in isolation, which may leave them susceptible to coordinated campaigns spanning multiple services. A system and method are described that can construct a unified cross-service behavioral graph to address such challenges. This graph can ingest and correlate metadata from user activities across disparate services, for example, productivity, payment, and communication platforms, to identify precursor signals that may be indicative of fraudulent intent. By analyzing patterns such as co-reviewing, temporal pulsing, and suspicious cross-service coordination (e.g., template creation), the system …
