New Cost Model For Feasibility Analysis Of Utilising Special Purpose Machine Tools, Ana Vafadar, Majid Tolouei-Rad, Kevin Haywood

Research outputs 2014 to 2021

Special purpose machine tools (SPMs) have been widely used to perform drilling-related operations in high volume production including within automotive component industries. The first step in designing and manufacturing a SPM is a feasibility analysis. Since SPMs have relatively higher investment cost than other machine tools, this task must be performed before any investment on the preparation of detailed design. The present paper explores an economic feasibility analysis strategy which aims to make logical decision by assessing the strengths and limitations of an SPM in comparison with other machine tools. The mathematical product cost model for SPMs is proposed for …

A Morphometric Study Of The Human Mandible In The Indian Population For Sex Determination, Maneesha Sharma, Rakesh K. Gorea, Arshdeep Gorea, Abdulwahab A. Abuderman

Research outputs 2014 to 2021

Sex determination from bones is important in forensic investigations for establishing identity in cases of mutilated bodies. Many morphometric criteria have been laid down for various bones for sex determination in previous studies. The present study aimed at setting up some parameters of the mandible as indicators of sex in the Indian population. The length of body of the mandible, angle of the mandible and minimum ramus breadth were considered as chief parameters for sex determination from dried bones obtained from the Departments of Anatomy in two medical colleges of Punjab and Chandigarh. There was a statistically significant difference found …

An Automated Approach For Digital Forensic Analysis Of Heterogeneous Big Data, Hussam Mohammed, Nathan Clarke, Fudong Li

Research outputs 2014 to 2021

The major challenges with big data examination and analysis are volume, complex interdependence across content, and heterogeneity. The examination and analysis phases are considered essential to a digital forensics process. However, traditional techniques for the forensic investigation use one or more forensic tools to examine and analyse each resource. In addition, when multiple resources are included in one case, there is an inability to cross-correlate findings which often leads to inefficiencies in processing and identifying evidence. Furthermore, most current forensics tools cannot cope with large volumes of data. This paper develops a novel framework for digital forensic analysis of heterogeneous …

Designing Journalism Capstone Units That Demonstrate Student Skills, Trevor Cullen

Research outputs 2014 to 2021

There are considerable differences in the structure, content, and delivery of tertiary journalism degrees in Australia as identified in a 2014 Office for Learning and Teaching (OLT) Innovation and Development Project report on graduate qualities and journalism curriculum renewal. To address this situation, the author argues for journalism capstone units, designed by both journalism educators and news editors, to include a series of agreed criteria and standards to guide journalism educators, and for journalism students to demonstrate not only a broad knowledge base together with research and communication skills but also entrepreneurial skills to help them adapt to new media …

Running To Well-Being: A Comparative Study On The Impact Of Exercise On The Physical And Mental Health Of Law And Psychology Students, Natalie K. Skead, Shane L. Rogers

Research outputs 2014 to 2021

Research indicates that, in comparison to other university students, law students are at greater risk of experiencing high levels of psychological distress. There is also a large body of literature supporting a general negative association between exercise and stress, anxiety and depression. However, we are not aware of any studies exploring the impact of exercise on the mental health of law students specifically. This article reports evidence of a negative association between exercise and psychological distress in 206 law and psychology students. Compared to psychology students, the law students not only reported greater psychological distress, but, in addition, there was …

Medicine In The Early Twenty-First Century: Paradigm And Anticipation - Epma Position Paper 2016, Olga Golubnitschaja, Babak Baban, Giovanni Boniolo, Wei Wang, Rostyslav Bubnov, Marko Kapalla, Kurt Krapfenbauer, Mahmood S. Mozaffari, Vincenzo Costigliola

Research outputs 2014 to 2021

Challenges of “standardisation” and “individualisation” have always been characteristic for medical services. In terms of individualisation, the best possible individual care is the ethical imperative of medicine, and it is a good right of any patient to receive it. However, in terms of standardisation, all the available treatments are based on guideline recommendations derived from large multi-centre trials with many thousands of patients involved. In the most optimal way, the standardisation and individualisation should go hand-in-hand, in order to identify the right patient treating him/her with the right medication and the right dose at the right time point!

Bio-Physical Closure Criteria Without Reference Sites: Realistic Targets In Modified Rivers, Melanie L. Blanchette, Mark Lund, Robyn Stoney, Digby Short, Colm Harkin

Research outputs 2014 to 2021

The use of reference sites for establishing closure criteria in areas disturbed by mining activities is common practice. ‘Reference’ sites are those considered to be largely unimpacted by anthropogenic activity (retaining desirable natural characteristics), and occurring near disturbed sites. Sites are considered rehabilitated when their biophysical condition approximates that of the reference site. However, this approach often creates impossible or unrealistic targets for miners seeking to close rehabilitated lands. For example, reference sites are often limited in availability (or non-existent) due to impacts by other land uses. Further, any available reference sites might not be realistic matches for the rehabilitated …

The Uyghur Population And Genetic Susceptibility To Type 2 Diabetes: Potential Role For Variants In Capn10, Apm1 And Fut6 Genes, Feifei Zhao, Dolikun Mamatyusupu, Youxin Wang, Honghong Fang, Hao Wang, Qing Gao, Hao Dong, Siqi Ge, Xinwei Yu, Jie Zhang, Lijuan Wu, Manshu Song, Wei Wang

Research outputs 2014 to 2021

Genome-wide association studies have successfully identified over 70 loci associated with the risk of type 2 diabetes mellitus (T2DM) in multiple populations of European ancestry. However, the risk attributable to an individual variant is modest and does not yet provide convincing evidence for clinical utility. Association between these established genetic variants and T2DM in general populations is hitherto understudied in the isolated populations, such as the Uyghurs, resident in Hetian, far southern Xinjiang Uyghur Autonomous Region, China. In this case–control study, we genotyped 13 single-nucleotide polymorphisms (SNPs) at 10 genes associated with diabetes in 130 cases with T2DM and 135 …

Diet And Nutrition Reverse Type 3 Diabetes And Accelerated Aging Linked To Global Chronic Diseases, Ian James Martins

Research outputs 2014 to 2021

The acceleration in the rate of chronic diseases that involve insulin resistance has become of global concern. The rate of the most prevalent chronic disease such as cardiovascular disease is linked to the metabolic syndrome, non alcoholic fatty liver disease (NAFLD) and other chronic diseases that include obesity, diabetes and neurodegenerative diseases. The gene-environment interaction in Western countries indicates that with urbanization access to food and its content may lead to induction of epigenetic alterations and identify the gene Sirtuin 1 (Sirt 1) to be responsible for the increased risk for insulin resistance and NAFLD relevant to Type 1, Type …

Research outputs 2014 to 2021

Blood samples were collected serially from 14 women with healthy pregnancies, beginning in gestational week 4 at the time of a positive pregnancy test through to the identification of a foetal heart by ultrasound. Six biomarkers were measured in the serum retrospectively including two reproductive hormones (progesterone and human chorionic gonadotrophin (hCG)) and four additional biomarkers (prostate-specific antigen (PSA), cancer antigen 15-3 (CA15-3), cancer antigen 125 (CA125) and pregnancy-associated plasma protein A (PAPP-A)) measured on a Siemens Centaur XP and a Roche Cobas e411 automated analysers, respectively. The progesterone and hCG results were unremarkable following established patterns, but distinctive patterns …

Towards A Participatory Netnography: Collaborating With Children In Virtual Worlds Research, Ashley Donkin, Donell Holloway, Lelia Green

Research outputs 2014 to 2021

The new sociology of childhood has encouraged social researchers to incorporate children in as much of the research process as possible. However, whilst some success has been achieved within traditional ethnographic studies, netnography has been slow to make this a reality. This article discusses the previous online research into children’s virtual worlds, which has rarely incorporated young children into the data collection or research analysis processes. The opportunity for researchers to use participatory approaches to collaborating with their child participants and collecting online data is limited due to ethical constraints. The ethical challenges of conducting netnography are compounded by a …

Impaired Energy Metabolism: Involvement In Neurodegenerative Processes And Cns Ageing, Veer B. Gupta, Vivek K. Gupta

Research outputs 2014 to 2021

World is experiencing a consistent and steady increase in the ageing population with even higher proportional differences in the developed countries. Increase in ageing populations is directly correlated with the increased prevalence of age-related degenerative diseases of the central nervous system (CNS) such as Alzheimer’s disease and various other forms of dementias, stroke, Parkinson’s disease, retinal degenerative disorders, Huntington’s’ disease, multiple sclerosis, psychiatric and behavioural disorders amongst others.

Type 3 Diabetes With Links To Nafld And Other Chronic Diseases In The Western World, Ian J. Martins

Research outputs 2014 to 2021

In the year 2015 it is now estimated that 30% of the Western World will now progress to non alcoholic fatty liver disease (NAFLD) and by the year 2050 if NAFLD remains untreated in the Western world the prevalence of the disease may rise to 40% of the global population. Type 3 diabetes and circadian rhythm disturbances may be involved in the induction of NAFLD that may promote insulin resistance and various chronic diseases such as cardiovascular disease, pancreatic disease, kidney disease and neurodegenerative disease. Multiple risk factors that induce Type 3 diabetes and NAFLD include stress, magnesium deficiency, bacterial …

Faculty Publications

The aim of this study was to determine the purpose and function of recreational family storytelling across the life span from the perspective of parents and their adult children. Twelve individuals were interviewed (six parents paired with one of their adult children). Questions focused on ascertaining the purpose and function of storytelling from the perspectives of parents and children in the same family unit. In these families storytelling created opportunities for family bonding. Storytelling accomplished its purpose of creating family bonds through five functions: being fun, dealing with difficult topics or situations, transferring beliefs and values as well as giving …

Assessing Alternative Techniques For Scaling The Family Leisure Activity Profile: Recommendations For Future Family Leisure Measurement, Karen K. Melton, Gary Ellis, Ramon Zabriskie

Faculty Publications

Psychometric properties of the Family Leisure Activity Profile (FLAP) were evaluated using family leisure and family functioning ratings from 884 parents and children residing in the United Kingdom. Review and critique of the FLAP resulted in identification and evaluation of three alternative scaling techniques. Scaling Technique 1was current practice, Technique 2 focused on family leisure environments rather than family leisure activities, and Technique 3 involved generating an estimate of duration of participation in family leisure in natural units of time. Inter-rater agreement and reliability were strong for all three scaling techniques. Technique 3 yielded the best model fit. Empirical relations …

In The Pursuit Of Happiness All Family Leisure Is Not Equal, Karen K. Melton, Ramon Zabriskie

Faculty Publications

In the context of family leisure, individuals are more likely to achieve happiness when recreating with their families in predictable activities and in familiar environments. This hypothesis was tested by comparing three models predicting individual happiness. The three models were grounded in distinct frameworks of family leisure incongruity: (a) the null model – all family leisure is equal; (b) activity incongruity model – familiar versus unfamiliar family activities; and (c) location incongruity model – indoor-home, outdoor-home, community, and beyond the community. Analyses used a sample of 1502 individuals in 751 families from the U.K. Models were assessed using multi-level modelling. …

Portfolio Spillovers And A Limit To Diversification, Bronson Argyle

Faculty Publications

Securities are exposed to the return shocks of seemingly unrelated securities in common mutual fund portfolios. Shocks to firm returns mechanically affect fund returns that hold these securities, which induce investor-driven flows and rebalancing, resulting in temporary flow-induced price pressure (FIPP) on other firms in common portfolios. Instrumenting to address flow/return endogeneity, a one standard deviation increase in the FIPP corresponds to a 15-60 bps increase in daily abnormal firm returns. This pressure reverses in 5-6 days and is larger for liquid firms and for funds experiencing outflows. Failing to properly estimate this correlation implies that an investor is exposed …

The Ownership And Trading Of Debt Claims In Chapter 11 Restructurings, Victoria Ivashina, Benjamin Iverson, David C. Smith

Faculty Publications

Using a novel data set that covers individual debt claims against 136 bankrupt US companies and includes information on a subset of claims transfers, we provide new empirical insight regarding how a firm’s debt ownership relates to bankruptcy outcomes. Firms with higher debt concentration at the start of the case are more likely to file prearranged bankruptcy plans, to move quickly through the restructuring process, and to emerge successfully as independent going concerns. Moreover, higher ownership concentration within a debt class is associated with higher recovery rates to that class. Trading of claims during bankruptcy concentrates ownership further, but this …

Identifying And Supporting Numeracy Needs Of First Year Undergraduate Education Students, Fiona Budgen, John West

Research outputs 2014 to 2021

Currently Australian pre-service teachers’ levels of personal numeracy are under a great deal of scrutiny. There are calls for universities to raise entry standards into teaching degrees and counter-calls that the output of universities should be gauged rather than inputs. In 2015, doubts about the ability of graduate teachers to convey the desired skills, knowledge and attitudes in mathematics led the Australian Government to mandate the introduction of the Literacy and Numeracy Test for Initial Teacher Education Students. From 2017, all pre-service teachers in Australia will be required to pass prior to graduation. The present research sought to identify specific …

The Wealth Of Subnations: Geography, Institutions, And Within-Country Development, Todd Mitton

Faculty Publications

I study determinants of economic development in a new dataset covering 1867 subnational regions from 101 countries, focusing on within-country effects of geography and institutions. Several geographic factors have significant explanatory power forwithin-country differences in per-capita GDP, including terrain ruggedness, tropical climate, ocean access, temperature range, storm risk, and natural resources such as oil, diamonds, or iron. Institutions have a significant positive effect on income among subnational regions with greater autonomy, suggesting that strong subnational institutions enhance development when not dominated by national institutions.

The Value Of Connections In Turbulent Times: Evidence From The United States, Daron Acemoglu, Simon Johnson, Amir Kermani, James Kwak, Todd Mitton

Faculty Publications

The announcement of Timothy Geithner as nominee for Treasury Secretary in November 2008 produced a cumulative abnormal return for financial firms with which he had a prior connection. This return was about 6% after the first full day of trading and about 12% after ten trading days. There were subsequently abnormal negative returns for connected firms when news broke that Geithner’s confirmation might be derailed by tax issues. Personal connections to top executive branch officials can matter greatly even in a country with strong overall institutions, at least during a time of acute financial crisis and heightened policy discretion.

Measurement And Outcomes Of Identity Communication In Virtual Teams, Susan A. Brown, Sherry M. B. Thatcher, David W. Wilson

Faculty Publications

Virtual teams play an important role in the modern economy, and many organizations struggle to overcome the weaknesses inherent in technologymediated work. Drawing from a strong empirical foundation for identity-related outcomes in nonmediated settings, we propose that perceived virtual identity communication accuracy positively impacts virtual team trust and performance. We further propose that capabilities of the communication medium can either support or hinder perceived virtual identity communication accuracy. In three studies with a cumulative sample of N=410, this research-in-progress paper reports on the first phase of a two-phase study. We develop survey scales for a medium’s identity communication capabilities and …

Leveraging Multimedia To Advance Science By Disseminating A Greater Variety Of Scholarly Contributions In More Accessible Formats, James Gaskin, Paul Benjamin Lowry, David Hull

Faculty Publications

For the welfare of the scientific community, we are intentionally rocking the boat with regards to the way we conduct, recognize, and disseminate scholarly contributions. As a scientific community, we are doing ourselves a great disservice by ignoring the insights, artifacts, discoveries, and conversations which naturally occur in the scientific process of advancing knowledge, but which do not fit into the very narrowly defined form of print-style articles. By failing to recognize, reward, and publish the wide variety of scholarly contributions that are not well suited to the print-style article, we hinder scientific progress, devalue important and necessary contributions to …

Application Of Expectancy Violations Theory To Communication With And Judgments About Embodied Agents During A Decision-Making Task, Judee K. Burgoon, Joseph Bonito, Paul Benjamin Lowry, Sean Humphreys, Gregory D. Moody, James Gaskin, Justin Giboney

Faculty Publications

Because users treat embodied agents (EAs) as social actors, users hold expectations about human-to-EA communication (HtEAC) similar to those in human-to-human communication. This study extends Expectancy Violations Theory (EVT) to examine how different forms of interfaces that confirm or violate user expectations affect the communication process, social judgments, ability to influence, and accuracy of recall associated with HtEAC. Positive violations of expectancy are acts or characteristics of the EA that are unexpected but evaluated favorably by the human partner. Results suggest that when the EA deviates from expectations, effects on the HtEAC process and related outcomes can be more pronounced. …

Institutional Drivers And Barriers To Faculty Adoption Of Blended Learning In Higher Education, Wendy W. Porter, Charles R. Graham

Faculty Publications

Relatively little research on blended learning (BL) addresses institutional adoption, although such research would benefit institutions of higher education in strategically adopting and implementing BL. In a prior study, the authors proposed a framework for institutional BL adoption, identifying three stages: (1) awareness/exploration, (2) adoption/early implementation, and (3) mature implementation/growth. The framework also identified key strategy, structure and support issues universities may address at each stage. The current study applies that framework as well as Rogers’ diffusion of innovations theory to determine the degree to which institutional strategy, structure and support decisions facilitate or impede BL adoption among higher education …
