Due to the reported efficacy of in vitro fertilization (IVF) this method of dealing with infertility is increasing being used. Experiencing IVF can be a source of psychological and emotional difficulties for couples trying to have a child. A systematic review was performed to discuss IVF as a psychological issue that impacts on the functioning of individuals, couples and families. Ebsco, Science Direct and PsycARTICLES databases were searched using the keywords: IVF fertilization, IVF psychology, infertility, and IVF consequences, using published peer reviewed articles from 2006 onwards. Studies in the English and Polish languages, peer reviewed and investigating general IVF …

Does Front-Loading Taxation Increase Savings? Evidence From Roth 401(K) Introductions, John Beshears, James J. Choi, David Laibson, Brigitte C. Madrian

Faculty Publications

Can governments increase private savings by taxing savings up front instead of in retirement? Roth 401(k) contributions are not tax-deductible in the contribution year, butwithdrawals in retirement are untaxed. The more common before-tax 401(k) contribution is tax-deductible in the contribution year, but both principal and investment earnings are taxed upon withdrawal. Using administrative data from eleven companies that added a Roth contribution option to their existing 401(k) plan between 2006 and 2010, we find no evidence that total 401(k) contribution rates differ between employees hired before versus after Roth introduction, which implies that take-home pay declines and the amount of …

Behaviorally Informed Policies For Household Financial Decisionmaking, Brigitte C. Madrian, Hal E. Hershfield, Abigail B. Sussman, Saurabh Bhargava, Jeremy Burke, Scott A. Huettel, Julian Jamison, Eric J. Johnson, John G. Lynch, Stephan Meier, Scott Rick, Suzanne B. Shu

Faculty Publications

Low incomes, limited financial literacy, fraud, and deception are just a few of the many intractable economic and social factors that contribute to the financial difficulties that households face today. Addressing these issues directly is difficult and costly. But poor financial outcomes also result from systematic psychological tendencies, including imperfect optimization, biased judgments and preferences, and susceptibility to influence by the actions and opinions of others. Some of these psychological tendencies and the problems they cause may be countered by policies and interventions that are both low cost and scalable. We detail the ways that these behavioral factors contribute to …

Psychogeography – Providing A Lens On Corporate Culture And Its Potential Impact On Career Success: A Novel And Efficient Approach, Dorothy Wardale, Linley Lord

Research outputs 2014 to 2021

Psychogeography refers to the loose interface between psychology and geography. Specifically it examines how we impact on the environment and the environment impacts on us. As a process it involves intimately observing the environment and seeing what may have been previously unobserved. Participants then construct meaning from these observations. This paper describes how we used a time-limited psychogeography approach followed immediately by a focus group as research method. The aim was to determine if examining participants’ work environment would potentially enable them to identify enablers and barriers to career success. The findings from these two short interventions are compared to …

Final Demand For Structured Finance Securities, Craig B. Merrill, Taylor Nadauld, Philip E. Strahan

Faculty Publications

Structured finance boomed during the run-up to the 2008 financial crisis. Highly rated, structured securities offered higher yield than other similarly rated bonds because of their concentration of systematic risk, but regulatory capital requirements did not account for this risk. As a result, regulated entities facing capital constraints had an incentive to invest in them. We show that life insurance companies exposed to unrealized losses from low interest rates in the early 2000s increased their holdings of highly rated securitized assets, consistent with regulatory arbitrage distorting the demand to hold these assets.

Gradient In Microstructure And Mechanical Property Of Selective Laser Melted Alsi10mg, Yujing Liu, Zeng Qian Liu, Y Jiang, G.W Wang, Yang Yang, Laichang Zhang

Research outputs 2014 to 2021

It is known that metal parts can be made stronger, tougher and better wear resistance by introducing gradient microstructure. This work reports the cooling rate of melt pool induced discrepancy in microstructural gradient and element distribution during selective laser melting (SLM), thereby resulting in decrease in microhardness and wear resistance from surface to inside with a range of ∼100 μm of SLM- manufactured AlSi10Mg alloy. The cooling rate in the top surface of melt pool reaches ∼ 1.44 × 10⁶ K/s, which is much higher than that at the bottom ( ≤ 1 × 10³ K/s). Such a …

Enhanced Corrosion And Wear Resistance Properties Of Carbon Fiber Reinforced Ni-Based Composite Coating By Laser Cladding, Jianbo Lei, Chuan Shi, Shenfeng Zhou, Zhenjie Gu, Laichang Zhang

Research outputs 2014 to 2021

To enhance the wear resistance and corrosion resistance of Ni-based coatings, carbon fibers reinforced nickel-based composite coatings (CFs/Ni) were fabricated on the surface of 1Cr13 stainless steel by laser cladding (LC). The microstructure characteristics, microhardness, wear and corrosion performances of the composite coatings were investigated. The results show that CFs can effectively improve the corrosion and wear resistances of Ni-based coatings. With increasing laser scanning speed, the morphology of CFs in composite coatings is more integral and the corrosion and wear resistances of the composite coatings are improved. Especially, when laser scanning speed is increased to 8 mm/s, the average …

Research outputs 2014 to 2021

Background

The Lower Limb Assessment Score (LLAS) has only been validated in a paediatric population. The aim of this study was to validate the use of the LLAS in an adult population by: i) evaluating its ability to discriminate between different extents of lower limb hypermobility, ii) establishing a cut-off score to identify lower limb hypermobility, and iii) determining if the LLAS is able to identify Generalised Joint Hypermobility (GJH).

Methods

Participants were recruited across three groups representing varying degrees of hypermobility. They were assessed using the LLAS, Beighton score and clinical opinion. Pearson’s correlation coefficient and MANOVA were used …

Similarities And Differences Between Simultaneous And Successive Bilingual Children: Acquisition Of Japanese Morphology, Yuki Itani-Adams, Junko Iwasaki, Satomi Kawaguchi

Research outputs 2014 to 2021

This paper compares the acquisition of Japanese morphology of two bilingual children who had different types of exposure to Japanese language in Australia: a simultaneous bilingual child who had exposure to both Japanese and English from birth, and a successive bilingual child who did not have regular exposure to Japanese until he was six years and three months old. The comparison is carried out using Processability Theory (PT) (Pienemann 1998, 2005) as a common framework, and the corpus for this study consists of the naturally spoken production of these two Australian children. The results show that both children went through …

What Do We Really Know About How Habituation To Warnings Occurs Over Time? A Longitudinal Fmri Study Of Habituation And Polymorphic Warnings, Anthony Vance, Brock Kirwan, Daniel Bjornn, Jeff Jenkins, Bonnie Brinton Anderson

Faculty Publications

A major inhibitor of the effectiveness of security warnings is habituation: decreased response to a repeated warning. Although habituation develops over time, previous studies have examined habituation and possible solutions to its effects only within a single experimental session, providing an incomplete view of the problem. To address this gap, we conducted a longitudinal experiment that examines how habituation develops over the course of a five-day workweek and how polymorphic warnings decrease habituation. We measured habituation using two complementary methods simultaneously: functional magnetic resonance imaging (fMRI) and eye tracking.

Our results show a dramatic drop in attention throughout the workweek …

A Ten-Year-Old’S Use Of Creative Content To Construct An Alternative Future For Herself, Lelia Rosalind Green, Kylie Justine Stevenson

Research outputs 2014 to 2021

The Hand Up Linkage project focuses on the family as a communication context through which to explore the dynamics of intergenerational welfare dependency. In particular, it explores ways that creative life-course interventions might allow children in welfare dependent families to construct alternative realities for themselves and alternative views of their future. Formed through an alliance between a key Western Australian social welfare not-for-profit organisation, St Vincent de Paul WA (SVDPWA and also, in the context of volunteers, ‘Vinnies’), and Edith Cowan University, the project aims to address the organisation’s vision to provide “a hand up” (St Vincent 1) rather than …

The Role Of Context In It Assimilation: A Multi-Method Study Of A Saas Platform In The Us Nonprofit Sector, Ryan T. Wright, Nicholas Roberts, David W. Wilson

Faculty Publications

Nonprofit organizations (NPOs) operate in environments characterized by growing competition for resources and greater stakeholder demands for accountability, which makes deploying and maintaining information systems a struggle. In this competitive, resource-constrained environment, enterprise Software-as-a-Service (SaaS) platforms offer NPOs a cost-effective way access reliable, low-maintenance information technology services. Thus, the extent to which NPOs assimilate SaaS is an important area of inquiry. Yet despite the wealth of research on organizational IT assimilation, we know little regarding whether, when, and how NPOs assimilate IT innovations. We further our understanding of NPO assimilation of SaaS by conducting a context-based study. To do so, …

Using Wearable Devices For Non-Invasive, Inexpensive Physiological Data Collection, James Gaskin, Jeffrey Jenkins, Thomas Meservy, Jacob Steffen, Katherine Payne

Faculty Publications

Using sensors to gather physiological data about users can provide valuable insights for Information Systems (IS) research that are not availed through traditional measures. While useful in many laboratory settings, many of these physiological sensors (e.g., fMRI, EEG, EKG, etc.) are impractical and severely limited in other scenarios due to (1) prohibitive cost, (2) small sample size, (3) invasiveness, and (4) the difficulty to match psychological traits to physiological measures. In this study, we demonstrate how inexpensive consumer-grade wearable technologies overcome these first three limitations while we extend existing research on exploring the fourth limitation.

This study was aimed to test the association between perceived stress and problematic social networking site (SNS) usage, and to figure outwhether psychological resiliencemoderated this relationship. The Perceived Stress Scale, Connor-Davidson Resilience Scale, and Facebook Intrusion Questionnaire were administered to 499 Chinese college students. The results showed that (1) perceived stress was positively associated with problematic SNS usage; (2) psychological resiliencewas negatively relatedwith problematic SNS usage; and (3) psychological resilience moderated the relationship between perceived stress and problematic SNS usage. Specifically, the relationship between perceived stress and problematic SNS usage was statistically significant for students with a lower level of …

The Higher-Ed Organizational-Scholar Tension: How Scholarship Compatibility And The Alignment Of Organizational And Faculty Skills, Values And Support Affects Scholar’S Performance And Well-Being, Milagros Pereyra-Rojas, Enrique Mu, James Gaskin, Tony Lingham

Faculty Publications

Scholars and institutions alike are concerned with academic productivity. Scholars not only further knowledge in their professional fields, they also bring visibility and prestige to themselves and their institutions, which in turn attracts research grants and more qualified faculty and graduate students. Many studies have been done on scholar productivity, and many of them focus on individual factors such as gender, marital status, and individual psychological characteristics. Also, a few studies are concerned about scholars’ well-being. We propose a causal model that considers the compatibility of the scholarship dimensions valued by scholars and institutions and their academic alignment with actual …

The Mediating Roles Of Upward Social Comparison And Self-Esteem And The Moderating Role Of Social Comparison Orientation In The Association Between Social Networking Site Usage And Subjective Well-Being, Jin-Liang Wang, Hai-Zhen Wang, James Gaskin, Skyler Hawk

Faculty Publications

The increased pervasiveness of social media use has raised questions about potential effects on users’ subjective well-being, with studies reaching contrasting conclusions. To reconcile these discrepancies and shed new light on this phenomenon, the current study examined: (1) whether upward social comparison and self-esteem mediate the association between social networking site (SNS) usage and users’ subjective well-being, and (2) whether the association between SNS usage and upward social comparison is moderated by users’ social comparison orientation. Data from 696 participants were collected. Structural equation modeling revealed that upward social comparison and self-esteem mediated the relationship between SNS usage and users’ …

Partly Cloudy, Scattered Clients: Cloud Implementation In The Federal Government, Elston H. Steele, Indira R. Guzman, James Gaskin, Monica Adya

Faculty Publications

While cloud computing adoption is on the rise, barriers continue to play a critical role in delaying the progress of some cloud computing adoption efforts. In 2010 the United States federal government launched the ‘Cloud First’ policy which requires government agencies to consider the adoption of cloud computing when the solution is secure, reliable and cost effective (Kundra, 2010). Unfortunately, cloud computing adoption among federal agencies has been sluggish. This study investigates pressures asserted to facilitate cloud computing adoption. Although a vast amount of literature exists, very few studies empirically investigate cloud computing adoption from an institutional perspective in concert …

Muddy Waters: Unintentional Consequences Of Blue Carbon Research Obscure Our Understanding Of Organic Carbon Dynamics In Seagrass Ecosystems, E. Fay Belshe, Miguel-Angel Mateo, Lucy Gillis, Martin Zimmer, Mirta Teichberg

Research outputs 2014 to 2021

The recent surge in research on organic carbon sequestration by seagrass ecosystems has begun to reveal the complexity of the carbon cycle within these ecosystems. In this prospective we discuss two areas of investigation that require further scrutiny: (1) why organic carbon is stabilized in seagrass sediments, and (2) how long organic carbon resides within these sediments. By delving into these topics, pointing out current pitfalls, and highlighting methodological advances, our motive is to focus future efforts and provide a frame work to manage the complexity found within the diverse seagrass bioregions. The high rate of seagrass degradation and loss, …

Older Australians Can Achieve High Adherence To The Mediterranean Diet During A 6 Month Randomised Intervention; Results From The Medley Study, Courtney Davis, Jonathan M. Hodgson, Janet Bryan, Manohar Garg, Richard Woodman, Karen Murphy

Research outputs 2014 to 2021

Adherence to a Mediterranean diet (MedDiet) is thought to be achievable in non-Mediterranean regions, but this has yet to be investigated. We aimed to determine if an older Australian population could adhere to a MedDiet for six months. We conducted a randomised, parallel dietary intervention trial with two dietary arms: the Mediterranean diet (MedDiet) group and the habitual diet (HabDiet) control group. A 15-point Mediterranean diet adherence score and food and nutrient intakes were estimated from three-day weighed food records collected at baseline, two and four months. Erythrocyte fatty acids, serum carotenoids and urinary metabolites were assessed at baseline, three …

Faculty Publications

This article describes the crossroads between learning analytics and learner engagement. The authors do this by describing specific challenges of using analytics to support student engagement from three distinct perspectives: pedagogical considerations, technological issues, and interface design concerns. While engaging online learners presents a major challenge to the educational community, the affordances of online learning environments and new advances in data analytics present many opportunities that can lead to improvements in our ability to fully engage students. The authors' work specifically underscores the fact that no single tool or system will be able to address all of the challenges involved. …

Thematic Patterns In International Blended Learning Literature, Research, Practices, And Terminology, Kristian J. Spring, Charles R. Graham

Faculty Publications

The goal of this research was to discover and compare themes of the top blended learning (BL) articles from seven different regions of the world. Top cited articles in BL from these regions show strong similarities in research processes, practice, terminology, and focus. Small differences are apparent among the regions and top articles in general, but similar patterns demonstrate that themes might promote collaboration and exchange between regions and that the most cited articles from around the world could fit well within the topical, research, and publication practices of the field. Our results suggest that although different regions must have …

An Evaluation Of The General Vs. Specialist Nature Of Top Accounting Journals, Scott L. Summers, David A. Wood

Faculty Publications

Academic research has a role in advancing and enlightening society in broad areas of study. Many forces interact to influence the directions, topics, and methodologies used in research. In this paper, we explore and discuss the relationships between the top general-interest and specialist accounting journals. We test whether top journals (e.g., “Top 3” or “Top 6”), relative to a set of high-quality but specialist journals, (1) are perceived to be general in what they will consider publishing, (2) have historically published diverse sets of articles, (3) have editorial board members with diverse sets of interests and skills, and (4) publish …

Factors Influencing Recruitment Of Non-Accounting Business Professionals Into Internal Auditing, Geoffrey D. Bartlett, Joleen Kremin, K. Kelli Saunders, David A. Wood

Faculty Publications

This paper examines factors affecting non-accounting business professionals’ willingness to work in internal auditing. In a 2 x 6 experiment with 502 participants from across the country, we find that, in contrast to prior research examining accountants, business professionals have relatively favorable views of internal audit. Although they hold favorable views, participants were still less likely to apply for a position labeled as internal audit than an identical position with an alternate label. Varying the structure of internal audit, including job responsibilities, career path, and sourcing arrangement, did not affect participants’ willingness to apply for an internal audit position. We …

Hopeful Monsters - In Defense Of Quests To Rediscover Long-Lost Species, David M. Watson, Robert A. Davis

Research outputs 2014 to 2021

Wild goose chase, snipe hunt, fool’s errand—these retorts typify responses of many biologists to news that someone is searching for a species considered extinct. Although these ventures can damage reputations and may offer false hope regarding the finality of extinction, genuine conservation gains often result, even for those quests that prove unsuccessful. As well as enhanced protection for regions where rediscovered species persist and new information of direct management relevance for co-occurring species, well-planned searches for long-lost species represent valuable engagement opportunities to raise awareness in the wider community about biodiversity conservation and science generally. Indeed, we suggest that “Lazarus …

Pso Algorithm For An Optimal Power Controller In A Microgrid, Waleed Al-Saedi, Stefan Lachowicz, Daryoush Habibi, Octavian Bass

Research outputs 2014 to 2021

This paper presents the Particle Swarm Optimization (PSO) algorithm to improve the quality of the power supply in a microgrid. This algorithm is proposed for a real-time selftuning method that used in a power controller for an inverter based Distributed Generation (DG) unit. In such system, the voltage and frequency are the main control objectives, particularly when the microgrid is islanded or during load change. In this work, the PSO algorithm is implemented to find the optimal controller parameters to satisfy the control objectives. The results show high performance of the applied PSO algorithm of regulating the microgrid voltage and …
