An important first step is to identify and describe the concept of meaningfulness as it is used in the chronic pain rehabilitation literature. Objective: This paper reports the findings of a structured concept analysis to define meaningfulness from the patient perspective in chronic pain rehabilitation. Methodology: In consultation with …

Interplay Between Residual Protease Activity In Commercial Lactases And The Subsequent Digestibility Of Β-Casein In A Model System, Di Zhao, Thao T. Le, Lotte B. Larsen, Yingqun Nian, Cong Wang, Chunbao Li, Guanghong Zhou

Research outputs 2014 to 2021

One of the conventional ways to produce lactose-hydrolyzed (LH) milk is via the addition of commercial lactases into heat-treated milk in which lactose is hydrolyzed throughout storage. This post-hydrolysis method can induce proteolysis in milk proteins due to protease impurities remaining in commercial lactase preparations. In this work, the interplay between lactose hydrolysis, proteolysis, and glycation was studied in a model system of purified β-casein (β-CN), lactose, and lactases using peptidomic methods. With a lactase presence, the proteolysis of β-CN was found to be increased during storage. The protease side-activities mainly acted on the hydrophobic C-terminus of β-CN at Ala, …

The term Blue Carbon (BC) was first coined a decade ago to describe the disproportionately large contribution of coastal vegetated ecosystems to global carbon sequestration. The role of BC in climate change mitigation and adaptation has now reached international prominence. To help prioritise future research, we assembled leading experts in the field to agree upon the top-ten pending questions in BC science. Understanding how climate change affects carbon accumulation in mature BC ecosystems and during their restoration was a high priority. Controversial questions included the role of carbonate and macroalgae in BC cycling, and the degree to which greenhouse gases …

A Corrective Justice Justification For Considering The Response Of The Hypothetical Person Of An “Ordinary Level Of Susceptibility” When Assessing Reasonable Foreseeability In Cases Involving Negligently Inflicted Psychiatric Injury, Martin Allcock

Research outputs 2014 to 2021

The law has long been concerned with limiting recovery for pure psychiatric injury in negligence in order to prevent liability to plaintiffs who are unusually susceptible to this type of injury. The justifications provided by courts for this concern have often centred on the idea that holding a defendant liable to such a plaintiff will be unreasonable. However, there is a gap in the reasoning of the courts and in the scholarly literature as to the potential theoretical justifications for measuring the reasonableness of the defendant’s conduct against the effect of that conduct on the hypothetical person of an “ordinary …

A Simheuristic Approach For Evolving Agent Behaviour In The Exploration For Novel Combat Tactics, Chiou-Peng Lam, Martin Masek, Luke Kelly, Michael Papasimeon, Lyndon Benke

Research outputs 2014 to 2021

The automatic generation of behavioural models for intelligent agents in military simulation and experimentation remains a challenge. Genetic Algorithms are a global optimization approach which is suitable for addressing complex problems where locating the global optimum is a difficult task. Unlike traditional optimisation techniques such as hill-climbing or derivatives-based methods, Genetic Algorithms are robust for addressing highly multi-modal and discontinuous search landscapes. In this paper, we outline a simheuristic GA-based approach for automatic generation of finite state machine based behavioural models of intelligent agents, where the aim is the identification of novel combat tactics. Rather than evolving states, the proposed …

Research outputs 2014 to 2021

BACKGROUND: Community-acquired pneumonia (CAP) is a major global disease. Parapneumonic effusions often complicate CAP and range from uninfected (simple) to infected (complicated) parapneumonic effusions and empyema (pus). CAP patients who have a pleural effusion at presentation are more likely to require hospitalization, have a longer length of stay and higher mortality than those without an effusion. Conventional management of pleural infection, with antibiotics and chest tube drainage, fails in about 30% of cases. Several randomized controlled trials (RCT) have evaluated the use of corticosteroids in CAP and demonstrated some potential benefits. Importantly, steroid use in pneumonia has an acceptable safety …

Born Again With Trump: The Portrayal Of Evangelicals In The Media, Eun-Young Julia Kim

Faculty Publications

Since Trump’s ascendancy in American politics and his subsequent election, a number of articles have surfaced in the media trying to explain evangelical voters’ support of Trump. This paper analyzes common descriptions and conceptions of evangelicals by identifying recurring descriptions of evangelicals in 110 online articles published in a two-and-a-half-year period surrounding Trump’s presidential campaign and election. The results indicate that the answer to the question as to why evangelicals support Trump resides not so much in their theology, but in their aspirations for America and assumptions of what America should be like. This paper argues that it is crucial …

Finding God In Community, S. Joseph Kidder, Jonny Wesley Moor

Faculty Publications

"God exists in community. Before the angels, before the universe, before perhaps time itself, the Father, Son, and Spirit shared a continuous love that can exist only in community.¹ Community is God’s primal manifestation of existence and reality. When God created humanity, He intended for us to be able to relate to Him, so the Lord made us male and female (Gen. 1:27), counterparts equal but distinct in community. Jürgen Moltmann argues that truly knowing something involves being able to participate with that entity.² For example, rather than learning physics merely to recite formulas and laws, …

Modelling Of The Radiant Heat Flux And Rate Of Spread Of Wildfire Within The Urban Environment, Greg Penney, Steven Richardson

Research outputs 2014 to 2021

One approach to increase community resilience to wildfire impacts is the enhancement of residential construction standards in an effort to provide protective shelters for families within their own homes. Current wildfire models reviewed in this study assume fire growth is unrestricted by vegetation fuel bed geometry; the head fire has attained a quasi-steady rate of spread; and the shielding effects of urban development are ignored. As a result, radiant heat flux may be significantly overestimated for small vegetation fires in road reserves, urban parklands, and similar scenarios. This paper proposes two new models to address this issue, and utilises two …

Assignment Of E-Commerce Orders To Fulfillment Warehouses, Ahmad Basem Zamka

Theses

For large e-commerce companies such as Amazon, when an order comes, this order might be available at more than one fulfillment centers. Therefore, the question of which fulfillment center this order should be fulfilled from would arise.

In a typical situation, customer demand is fulfilled from the closest fulfillment center. However, this approach does not always provide the optimal solution since there are so many factors that could be involved in making such a decision. These factors might include inventory balance, product correlations, and future demand.

Our decision model focuses on putting future orders in consideration while assigning orders to …

Interval Training Methods To Increase Performance Markers And Load Carriage In Tactical Professionals, Nathan D. Dicks

Health Nutrition and Exercise Science

Load carriage is an inherent part of the military and other tactical occupations (e.g., law enforcement, firefighters). Variation in load carriage ranges from 7-60 kg and can increase energy expenditure as well as lead to higher injury risk. Various novel training methods such as low-intensity interval training (LIT) in combination with blood flow restriction (BFR) as well as high-intensity interval training (HIT) aim at enhancing critical velocity (CV), aerobic fitness, and load carriage performance. Two investigations identified the feasibility of LIT with BFR and the use of HIT to increase performance and load carriage. Methods: Twelve male participants (21.8 +/- …
