Temptation At The School Fence: A Qualitative Exploration Of The Impact Of External Food Outlets On The School Community, Sharonna Mossenson, Klug, Jacinta Francis, Siobhan Hickling, Lukar Thornton, Gina Trapp

Research outputs 2022 to 2026

Retail food outlets are commonly located in close proximity to schools, providing students with opportunities to purchase and consume food enroute to or from school. These outlets are typically unhealthy and disproportionately clustered near schools, and this trend has been increasing over time. While quantitative studies have established associations between school food environments and adolescent dietary behaviours, little is known about how school personnel perceive and experience their impacts. This qualitative study explored perspectives of school personnel (n = 9) from a secondary school in Perth, Western Australia, located 150 m from two retail food precincts (areas with a high …

Pretorius, Thomas R. Sullivan, Summer V.M. Walker, Johan Garssen, Jeffrey A. Keelan, Desiree Silva, Susan L. Prescott, Debra J. Palmer

Research outputs 2022 to 2026

Background: Prebiotic dietary supplementation has been shown to improve glucose homeostasis in type 2 diabetes patients. The aim of this analysis was to determine whether pre-pregnancy body mass index (BMI) modifies the effect of prebiotic supplementation from mid-pregnancy on reducing the risk of gestational diabetes mellitus (GDM). Methods: In a double-blinded, randomised controlled trial, pregnant women < 21 gestational weeks were randomly assigned (1:1) to consume daily prebiotics (14.2 g galacto-oligosaccharides and fructo-oligosaccharides) or placebo (8.7 g maltodextrin) powder. An effect modification analysis was performed to assess the heterogeneity of the effect of prebiotic supplementation in relation to pre-pregnancy BMI on GDM diagnosis. Results: Between June 2016 and November 2021, 329 women were assigned to the prebiotic group (50.4%), and 323 (49.5%) were assigned to the placebo group. Overall, 288 of 652 women (44.2%) were classified as overweight/obese prior to pregnancy (BMI ≥ 25 kg/m²). The distribution was balanced, with 146/329 (44.4%) randomised to the prebiotics group and 142/323 (44.0%) in the placebo group. Pre-pregnancy BMI modified the effect of prebiotic supplementation, with the intervention reducing GDM rates in women with a BMI ≥ 25 kg/m^{2 …}

Horizontal Regulatory Barriers In International Trade: Evidence From Electric Plugs, Yuan Mei, Mingzhi (Jimmy) Xu

Research Collection School Of Economics

Domestic policies regulating the horizontal dimensions of product differentiation can impede international trade and have become a major concern in contemporary trade negotiations. We estimate trade frictions associated with incompatible designs of electric plugs, a well-known example of a horizontal regulatory barrier. Our findings indicate that fewer electronic devices are exported to destinations with incompatible electric plugs, and this effect operates through both the extensive margin and the intensive margin of exports. These results are further corroborated by an online survey of Chinese electronics exporters. Moreover, incompatible plugs are associated with lower average quality of exported electronic devices, suggesting that …

Rad Dudes, Rude ‘Tude, And The Family, Too: How Nintendo And Sega Advertisements Shaped The Image Of Gaming In The 1990s, Megan Condis, Jess Morrissette

Political Science Faculty Research

The tale of the console wars of the 1990s, the stodgy, conservative, family-friendly Nintendo consoles waging an advertising war against the rebellious upstarts behind the Sega Genesis, has been told many times over. These histories are “typically a mix between summaries of factual data and interviews of the key actors who were part of the events” (Arsenault 2017, p. 9). However, there has been relatively little research taking a systematic approach to measuring the veracity of these narratives. This article aims to supplement those histories by examining an archive of 2,875 print video game advertisements spanning from 1989 to 1995. …

In-Process Large Language Model Requesting Through Knowledge Graphs For Interfacing With Manufacturing Digital Twins, Reiki Tanaya Karuka, Vinh Nguyen

Michigan Tech Publications

Digital twins (DTs) have potential to improve manufacturing processes by providing in-process monitoring and reducing trial-and-error while improving process prediction and performance. However, identifying anomalies or defects in a DT environment remains a very time intensive process that requires multidisciplinary expertise and significant manual effort in analyzing the system. Large language models (LLMs) offer potential capabilities to interpret system-level information and support user-driven querying, but their effectiveness is limited by hallucinations when reasoning over large and dynamic manufacturing datasets inherent to process monitoring DTs. Knowledge graphs (KGs) have emerged as efficient tools in the industrial domain to efficiently represent data …

Underground transit systems (Subway) are susceptible to frequent heat waves, which pose serious health and safety risks to commuters and transit workers. Yet, the patterns and extent of temperature changes within the subway system remain insufficiently understood. To address this gap, we conducted a study of thermal variability across 112 subway stations in New York City. Temperature and relative humidity were measured at both platform and street levels. Results show that during the summer, 70% of subway stations had platform heat index higher than street level heat index. We also developed a machine learning forecasting model to predict platform-level temperatures. …

Dataset For Integrity Attacks On Time Synchronized Synchrophasor Data, Taylah Griffiths, Mohiuddin Ahmed, Chadni Islam

Research outputs 2022 to 2026

Phasor measurement units, also known as synchrophasors, are a vital component within smart grids to determine the stability of the grid. These devices send synchrophasor data to phasor data concentrators that collate and analyse the data. Recently, synchrophasor communication data has become beneficial for the research community. However, datasets covering cyberattacks on synchrophasor data are not public. Having access to this data would aid in investigating mitigations against cyberattacks. This paper describes a public specialized dataset, known as ECU-PMU-FDI/TSA. The dataset contains synchrophasor communication data for cybersecurity mitigation testing. Three hours of communication data was captured, from a simulated testbed. …

Genetic Drivers Of Progression In Alzheimer’S Disease Are Distinct From Disease Risk, Celeste E. Cohen, Shane Fernandez, Umran Yaman, Ahmad R. Ehyaei, Eleftheria Kodosaki, Aydan Askarova, Tenielle Porter, Eleanor O’Brien, Paul Maruff, Alexi Nott, John A. Hardy, Simon M. Laws, Dervis A. Salih, Maryam Shoai

Research outputs 2022 to 2026

Background: Recent trials in Alzheimer’s disease (AD) demonstrate encouraging outcomes. These trials target risk mechanisms identified through genetic analysis whilst directly aiming to reduce progression rates. Evidence from other neurodegenerative diseases suggests the genetics of progression is distinct from risk of disease. To expand these initial successes and improve clinical outcomes further we need to understand genetics of progression of disease. These can be deduced through rigorous analysis of meticulously phenotyped longitudinal cohorts. In this study we first looked at known genetic drivers of risk, namely polygenic risk scores for AD and APOE‑ε4, to assess their role in progression. This …

Over A Century Of Global Decline In The Growth Performance Of Marine Fishes, Helen F. Yan, Hannah V. Watkins, Alexandre C. Siqueira, David R. Bellwood

Research outputs 2022 to 2026

Human-driven pressures are causing large-scale changes in the ecologies and life histories of fishes. Growth performance is a composite life-history trait that captures the trade-off between two fundamental traits: growth and body size. Here, we assess the impacts of fishing and temperature on the growth performance of marine teleost fishes globally over the last century. Using 7683 growth curves encompassing 1479 species, we find a global pattern of decline in growth performance from 1908 onwards, with the greatest declines in commercially valuable fishes. Indeed, managed fisheries experienced a 9% decline in growth performance over the last century, which can equate …

Adding A Weight To Constrain The Trunk Increases Knee Joint Kinetics During Sidestep Cutting In Female Athletes, Daniel Kadlec, J. Jordan, Jacqueline Alderson, Sophia Nimphius

Research outputs 2022 to 2026

Sidestep cutting exposes the knee to high multiplanar loads that both challenge tissue capacity and provide an opportunity to develop resilience through progressive exposure. This study investigated task constraints applied at the trunk and preparatory step and changes in lower-body joint kinetics associated with ACL injury risk during sidestepping in female athletes. Twenty-one trained female athletes performed six sidestep conditions: pre-planned and unplanned sidesteps, each with and without trunk (holding ~ 5–7.5% body mass at chest level) and preparatory-step (ducking under an adjustable rope at eye height) constraints. Relative joint power at the hip, knee, and ankle was analysed using …

Unpacking Environmental Racism Through Dependency Theory In The Case Of Second-Hand Goods Export To West Africa, Prince Nii Koi Kotei, Adusei-Asante, Shajimon Peter, Portia Nana Ama Brempong

Research outputs 2022 to 2026

The second-hand goods export market is complex and inextricably intertwined with environmental racism and dependency theories. Studies have shown that the adverse impacts of second-hand goods exports outweigh their benefits. West African countries are marginalised and are trapped in a dependency cycle. The literature discusses secondhand goods exports; however, it rarely situates this within the context of the dependency theory and environmental racism. This study seeks to address this gap by integrating several studies under a common theoretical framework connecting dependency theory to environmental racism. This study unpacks environmental racism through dependency theory in the export of second-hand goods. Specifically, …

Aluminium Based Hydrotalcite Like Compounds For Direct Lithium Extraction: A Critical Review On Crystallography And Structure Selectivity Design, Amin Sarmadi, Yasaman Boroumand, Mohammad Mahdi A. Shirazi, Magdalena Wajrak, Shayan Abrishami, Matthew Myers, Muhammad Rizwan Azhar, Amir Razmjou

Research outputs 2022 to 2026

The accelerating demand for lithium is intensifying interest in direct lithium extraction (DLE) technologies that minimise the environmental footprint of conventional solar evaporation ponds. Among sorbent-based DLE concepts, aluminium based hydrotalcite like compounds (Al-HTlc), particularly lithium aluminium layered double hydroxide (LiAl-LDH), are considered the most mature sorbent options, offering facile lithium (Li+) recovery and high selectivity in highly saline chloride based solutions. Both properties arise from a distinct intercalation mechanism wherein Li+ and its counter-anions (e.g. Cl− or SO42−) are co-intercalated into the crystal structure upon brine exposure. Li+ selectivity arises partly from a steric match between Li+ (ionic radius …
