Multiracial Identity As A Factor In Body Image And Disordered Eating, Kerrie Leonard

Human Development and Family Science

Emerging adulthood is a significant developmental stage where both ethnic-racial identitydevelopment and body dissatisfaction/disordered eating are salient. Past research suggests that there are links between identity development and body image/disordered eating (Palmeroni et al., 2020). Additionally, studies in the body image/disordered eating field have begun to examine differences among ethnic-racial groups (see Bucchianeri et al., 2016). However, there is limited research with Multiracial individuals (i.e., individuals with two or more ethnic-racial backgrounds). It is undetermined how Multiracial identity development influences body image and disordered eating behaviors. Thus, two studies were conducted to explore such connections. Participants included 174 Multiracial emerging …

A Professional Development Plan For Educators Working With Children With Autism Spectrum Disorder Transitioning Into Standard Childcare Settings, Jennifer Lee Reiser

Human Development and Family Science

Standard childcare centers are continuing to become more inclusive to individuals of all abilities. Transition plans from specialized services such as Applied Behavior Analysis (ABA) often include discharge criteria and a discharge transition plan for the child, but often do not include any training or development plan for educators in a standard childcare setting. Due to the limited number of plans available, transition plans vary greatly in how comprehensive they are as every organization creates their own plan or transitions children into the childcare setting without an identified plan. This paper proposes a professional development plan for educators working with …

Tracking Body Dissatisfaction And Body Ideals Of Ethnically Diverse College Women, Emma Johnson

Human Development and Family Science

Globally, women are exposed to society-created, unachievable body ideals, which change over time and are subject to influence by other, typically Western, societies. Socializing agents such as family members, peers, and media often reinforce these ideals through pressure, which can then lead to body dissatisfaction. Research on body ideals and body dissatisfaction disproportionately focuses on White women within the United States. While this group is important to continue to examine, there is a need to include women from outside of the United States and from Non-Western societies. Thus, this study examined college women’s perceptions of body ideals within and outside …

One of the leading algorithms in the current data-driven technology era is a deep learning approach, which is based on the concept of multiple hidden layers in a neural network. RUL prediction is an important part of PHM, which is the science that is aimed at increasing …

A Domain-Knowledge Modeling Of Hospital-Acquired Infection Risk In Healthcare Personnel From Retrospective Observational Data: A Case Study For Covid-19, Phat Huynh

Industrial and Manufacturing Engineering

Healthcare personnel (HCP) is facing a consistent risk of viral infections. We proposed a domain-knowledge-driven infection risk model to quantify the individual HCP and the population-level risks. For individual-level risk estimation, a time-variant model was proposed to capture the disease transmission dynamics. At the population-level, the infection risk was estimated using a Bayesian network model constructed from three feature sets. For model validation, we investigated the case study of the Coronavirus disease. The variance-based sensitivity analysis indicated that the uncertainty in the estimated risk was attributed to two variables: the number of close contacts and the viral transmission probability. We …

Sulfur Compounds: From Plants To Humans And Their Role In Chronic Disease Prevention, Caroline R. Hill, Armaghan Shafaei, Lois Balmer, Joshua R. Lewis, Jonathan M. Hodgson, A. Harvey Millar, Lauren C. Blekkenhorst

Research outputs 2022 to 2026

Sulfur is essential for the health of plants and is an indispensable dietary component for human health and disease prevention. Its incorporation into our food supply is heavily reliant upon the uptake of sulfur into plant tissue and our subsequent intake. Dietary requirements for sulfur are largely calculated based upon requirements for the sulfur-containing amino acids (SAA), cysteine and methionine, to meet the demands for synthesis of proteins, enzymes, co-enzymes, vitamins, and hormones. SAA are found in abundance in animal sources and are relatively low in plants. However, some plants, particularly cruciferous and allium vegetables, produce many protective sulfur-containing secondary …

An Optimal Charging Solution For Commercial Electric Vehicles, Bassam Al-Hanahi, Iftekhar Ahmad, Daryoush Habibi, Pravakar Pradhan, Mohammad A.S. Masoum

Research outputs 2022 to 2026

New government regulations and incentives promote the deployment of commercial electric vehicles to reduce carbon emissions from gasoline-fueled vehicles. For commercial electric vehicles (CEVs) operating in a fleet, charging processes are often performed at the depot where they begin and end their daily driving cycles, as well as at public stations on their routes. With the large penetration of CEVs in depots, simultaneous charging increases peak demand, which in turn impacts the electric network and increases the demand cost of a facility. These depot charging conditions influence the charging schedules of CEVs along their routes and the total service cost …

The reasons for this are likely the contested nature of quality criteria by which Arts-Based Practice is evaluated as well as the challenges as well associated with the dissemination of research findings. Mixed-methods research is increasingly recognised as an appropriate and practical approach for education phenomena, and within this domain, inquiry that combines traditional qualitative and arts-based strategies offers the education researcher advantages that are not readily available through other approaches. As professional artists and researchers we share our …

A New Comprehensive Dimensionless Inflow Performance Relationship For Gas Wells, Azim Kalantariasl, Isa Farhadi, Soosan Farzani, Alireza Keshavarz

Research outputs 2022 to 2026

Prediction of gas well deliverability is important for reservoir management. Conventional flow after flow, isochronal or modified isochronal tests are common methods for calculation of well deliverability. Single-point test using Vogel-type dimensionless inflow performance relationships (IPR) was also proposed to overcome the need for multi-point tests. However, analysis of field data showed that existing dimensionless IPR correlations fail to accurately predict well deliverability for some reservoir conditions. In this study, a wide range of reservoir rock and fluid data was used to develop a comprehensive dimensionless IPR correlation for calculation of gas well deliverability from single-point test data. Multi-point well …

Elastic Tubes: The Ideal Equipment For Telehealth Exercise Medicine In The Management Of Prostate Cancer?, Georgios Mavropalias

Research outputs 2022 to 2026

Prostate cancer (PCa) affects 1 in 8 men, but exercise therapy has been shown to be a very effective intervention not only to induce physiological benefits but to also reduce the side effects of cancer treatments typically administered during PCa. The COVID19 pandemic has restricted access to exercise clinics, a problem which always existed for people living in rural and remote areas. This caused many exercise physiologists and researchers to transition their clinic-based exercise to online, home-based exercise. We would like to propose that researchers and exercise physiologists should consider the use of elastic tubes in both research and the …

Three Essays On Renewable Jet Fuel Supply Chain Network Design And Traffic Safety, Sajad Ebrahimi

Transportation Logistics and Finance

Because of rising energy consumption, climate change, and environmental concerns about fossil fuels, finding alternative renewable energy sources is becoming increasingly crucial. With the non-advanced share of the U.S. Renewable Fuel Standard having been mainly met by corn ethanol, many states are considering cellulosic or non-edible oilseed crops as the next source of biofuels. This study seeks to design a supply chain to produce renewable jet fuel (RJF) within the Midwest region and southeastern U.S. This is accomplished through the use of optimization models (mixed-integer linear programming). Furthermore, because RJF manufacturing incurs higher expenses than conventional jet fuel, the use …

Hydrogen Diffusion In Coal: Implications For Hydrogen Geo‐Storage, Alireza Keshavarz, Hussein R. Abid, Muhammad Ali, Sefan Iglauer

Research outputs 2014 to 2021

Hypothesis

Hydrogen geo-storage is considered as an option for large scale hydrogen storage in a full-scale hydrogen economy. Among different types of subsurface formations, coal seams look to be one of the best suitable options as coal’s micro/nano pore structure can adsorb a huge amount of gas (e.g. hydrogen) which can be withdrawn again once needed. However, literature lacks fundamental data regarding H₂ diffusion in coal.

Experiments

In this study, we measured H₂ adsorption rate in an Australian anthracite coal sample at isothermal conditions for four different temperatures (20 °C, 30 °C, 45 °C and 60 °C), at …

Research outputs 2014 to 2021

Shift workers employed at a remote mining operation may experience sleep loss, impaired alertness, and consequently negative health and safety outcomes. This study determined the sleep behaviors and prevalence of risk for sleep disorders among shift workers; and quantified alertness for a roster cycle. Sleep duration was significantly less following; night shift by 77 ± 7 min and day shift by 30 ± 7 min. The wake after sleep onset was less by 23 ± 3 min for night shifts and 22 ± 3 min for day shifts (p < 0.05 for all). The prevalence of risk for sleep apnea was 31%, insomnia was 8%, and shiftwork disorder was 44%. Average alertness for all working hours was 75%. Shiftwork in remote mining operations is a significant factor that leads to sleep loss and reduced alertness, which is exacerbated by the high prevalence of risk for sleep disorders.
