Metamorphic Robustness Testing: Exposing Hidden Defects In Citation Statistics And Journal Impact Factors, Zhi Q. Zhou, T.H. Tse, Matt Witheridge Jan 2019

Metamorphic Robustness Testing: Exposing Hidden Defects In Citation Statistics And Journal Impact Factors, Zhi Q. Zhou, T.H. Tse, Matt Witheridge

Faculty of Engineering and Information Sciences - Papers: Part B

We propose a robustness testing approach for software systems that process large amounts of data. Our method usesmetamorphic relations to check software output for erroneous input in the absence of a tangible test oracle. We use this technique to testtwo major citation database systems: Scopus and the Web of Science. We report a surprising finding that the inclusion of hyphensin paper titles impedes citation counts, and that this is a result of the lack of robustness of the citation database systems in handlinghyphenated paper titles. Our results are valid for the entire literature as well as for individual fields such ...


Improved Performance Of Ballasted Tracks Under Impact Loading By Recycled Rubber Mats, Ngoc Trung Ngo, Buddhima Indraratna, Cholachat Rujikiatkamjorn Jan 2019

Improved Performance Of Ballasted Tracks Under Impact Loading By Recycled Rubber Mats, Ngoc Trung Ngo, Buddhima Indraratna, Cholachat Rujikiatkamjorn

Faculty of Engineering and Information Sciences - Papers: Part B

Ballasted tracks at transition locations such as approaches to bridges and road crossings experience increasing degradation and deformation due to dynamic and high impact forces, a key factor that decreases the stability and longevity of railroads. One solution to minimise ballast degradation at the transition zones is using rubber energy absorbing drainage sheets (READS) manufactured from recycled tyres. When placed beneath the ballast layer, READS distributes the load over wider area and attenuate of the load over a longer duration thus decreasing maximum stress, apart from reducing the energy transferred to the ballast and other substructure components. Subsequently, the track ...


Impact Of Climate Change And Human Activity On Soil Landscapes Over The Past 12,300 Years, Leo Rothacker, Anthony Dosseto, Alexander Francke, Allan Chivas, Nathalie Vigier, Anna M. Kotarba-Morley, Davide Menozzi Jan 2018

Impact Of Climate Change And Human Activity On Soil Landscapes Over The Past 12,300 Years, Leo Rothacker, Anthony Dosseto, Alexander Francke, Allan Chivas, Nathalie Vigier, Anna M. Kotarba-Morley, Davide Menozzi

Soils are key to ecosystems and human societies, and their critical importance requires a better understanding of how they evolve through time. However, identifying the role of natural climate change versus human activity (e.g. agriculture) on soil evolution is difficult. Here we show that for most of the past 12,300 years soil erosion and development were impacted differently by natural climate variability, as recorded by sediments deposited in Lake Dojran (Macedonia/Greece): short-lived ( < 1,000 years) climatic shifts had no effect on soil development but impacted soil erosion. This decoupling disappeared between 3,500 and 3,100 years ago, when the sedimentary record suggests an unprecedented erosion event associated with the development of agriculture in the region. Our results show unambiguously how differently soils evolved under natural climate variability (between 12,300 and 3,500 years ago) and later in response to intensifying human impact. The transition from natural to anthropogenic landscape started just before, or at, the onset of the Greek 'Dark Ages' (~3,200 cal yr BP). This could represent the earliest recorded sign of a negative feedback between civilization and environmental impact, where the development of agriculture impacted soil resources, which in turn resulted in a slowdown of civilization expansion.

The value of history is, indeed, not scientific but moral … it prepares us to live more humanely in the present, and to meet rather than to foretell, the future - Carl Becker. Becker's quote reminds us of the importance of revealing and understanding historical practices in order to influence actions in the future. There are compelling reasons for uncovering this history, in particular to better inform government policy makers and health advocates, and to address the impacts of growing community expectations to 'make the punishment fit the crime'.

HIV is an inherently gendered disease in eastern and southern Africa, not only because more women than men are infected, but also because socially constructed gender norms work to increase women's HIV-infection risk. The provision of cash transfers to young women alone in such a context adds another dimension to already existing complex social relations where patriarchal values are entrenched, gender inequality is the norm, and violence against women and girls is pervasive. It raises concerns about complicating young women's relationships with their male partners or possibly even setting them up for more violence. In our attempt to ...

A Contribution To Understanding The Impact Of Variations In Body Mass On Fractionating The Metabolic Burden Of Military Load Carriage, Heather Bowes, Catriona A. Burdon, Nigel A.S. Taylor

Faculty of Science, Medicine and Health - Papers: part A

Purpose: The oxygen cost associated with load carriage is dependent upon both its mass and its placement about the body. For occupations in which load carriage is routinely performed, and involves identical loads for all individuals, the relative metabolic cost varies inversely with body mass. However, whilst we understand the average impact of varying load placement, our appreciation of its impact on a morphologically diverse, contemporary workforce is very limited. Methods:The relationship between load placement and body mass was evaluated in 65 men (23.0 y [SD 3.0]; 80.5 kg [SD 1.7]: range 56.0-109.8 ...

Impact Of Structural Design Solutions On The Energy And Thermal Performance Of An Australian Office Building, Mehdi Robati, Georgios Kokogiannakis, Timothy J. Mccarthy

Faculty of Engineering and Information Sciences - Papers: Part B

Concrete is a heavyweight construction material whose high thermal mass could increase the thermal storage capacity of a building envelope and in turn affect indoor thermal comfort. Selecting an appropriate method for concrete construction and form could also affect the total energy performance and thermal comfort of a building, a fact that is often overlooked by structural engineers. This study presents the results of energy simulations of the potential impact that concrete construction forms, in particular two slab types, and structural materials have on the energy consumption of archetypal commercial office buildings in five major Australia cities (Sydney, Melbourne, Canberra ...

The Impact Of Marketing And Advertising On Food Behaviours: Evaluating The Evidence For A Causal Relationship, Jennifer A. Norman, Bridget Kelly, Emma J. Boyland, Anne T. Mcmahon

Faculty of Social Sciences - Papers

The prevention of overweight in childhood is paramount to long-term heart health. Food marketing predominately promotes unhealthy products which, if over-consumed, will lead to overweight. International health expert calls for further restriction of children¿s exposure to food marketing remain relatively unheeded, with a lack of evidence showing a causal link between food marketing and children¿s dietary behaviours and obesity an oft-cited reason for this policy inertia. This direct link is difficult to measure and quantify with a multiplicity of determinants contributing to dietary intake and the development of overweight. The Bradford Hill Criteria provide a credible framework by ...

Impact Resistance Of Ultra-High Strength Concrete Beams With Frp Reinforcement, Alex M. Remennikov, Matthew Goldston, M Neaz Sheikh

Faculty of Engineering and Information Sciences - Papers: Part A

Composite materials, including Fibre Reinforced Polymer (FRP) bars, have been used for decades in the structural and civil engineering sectors over traditional steel reinforcement. The main reasons for this are that FRP composites possess a number of advantages. They are non-corrosive, non-conductive, and lightweight and possess high longitudinal tensile strength. This paper presents the results of an experimental investigation into the effects of the use of glass FRP (GFRP) bars as internal reinforcement on the behaviour of concrete beams with high strength concrete (HSC) and ultra-high strength concrete (UHSC). Both static and dynamic (impact) behaviours of the beam have been ...

Effective Utilization Of Available Pev Battery Capacity For Mitigation Of Solar Pv Impact And Grid Support With Integrated V2g Functionality, Md Jan E Alam, Kashem M. Muttaqi, Danny Sutanto

Faculty of Engineering and Information Sciences - Papers: Part A

Utilizing battery storage devices in plug-in electric vehicles (PEVs) for grid support using vehicle-to-grid (V2G) concept is gaining popularity. With appropriate control strategies, the PEV batteries and associated power electronics can be exploited for solar photovoltaic (PV) impact mitigation and grid support. However, as the PEV batteries have limited capacity and the capacity usage is also constrained by transportation requirements, an intelligent strategy is necessary for an effective utilization of the available capacity for V2G applications. In this paper, a strategy for an effective utilization of PEV battery capacity for solar PV impact mitigation and grid support is proposed. A ...

Faculty of Social Sciences - Papers

Language framed as derogatory names and symbols can have implications for people and their life experiences. Within a Saussurian-inspired frame, and looking at ideas of stigma and social inclusion, this paper examines the use of language as a weapon within a social context of (changing) intent and meaning. Three examples of language use in mainstream society are analysed: 'retarded' which evolved from scientific diagnosis to insult; 'gay' as a derogatory adjective within popular culture; and, the way language around suicide is used to both trivialise and stigmatise those who are suicidal, as well as those who are bereaved.


The Impact Of Marketing Of 'Junk' Foods On Children's Diet And Weight, Bridget P. Kelly, Lesley King Jan 2015

The Impact Of Marketing Of 'Junk' Foods On Children's Diet And Weight, Bridget P. Kelly, Lesley King

Faculty of Social Sciences - Papers

Contemporary Western(ised) society is typified by pervasive and aggressive brand promotion, through all communication platforms. Food promotion in particular is a dominant area of marketing, particularly the marketing by large multinational food companies that manufacturer less healthy foods and beverages (Cairns et al. , 2013). The ubiquitous marketing of these unhealthy foods contributes to creating a negative food culture that undermines international and national nutrition recommendations and guidelines for disease prevention. Specifically, frequent exposure to persuasive promotions for unhealthy foods serves to normalise these food products as part of everyday life, create positive brand images, and ultimately encourage (over) consumption ...

In many domains, it is estimated that approximately 10,000 hours of planned learning activities are required to reach an expert level of performance. However, this poses a challenge for learners to balance such extensive learning times with the demands of everyday life. In our study we focused on activities in the domain of chess. We hypothesized that chess-related activities could be better integrated in an individual's life if exogenous resources - specified in the educational capital approach (Ziegler & Baker, 2013) - are sufficiently available. In order to test this hypothesis we introduced the concept of the Domain Impact Level of ...
