Identity Work By A Non-White Immigrant Business Scholar: Autoethnographic Vignettes Of Covering And Accenting, Mario Fernando, James Reveley, Mark Learmonth
Identity Work By A Non-White Immigrant Business Scholar: Autoethnographic Vignettes Of Covering And Accenting, Mario Fernando, James Reveley, Mark Learmonth
Faculty of Business - Papers (Archive)
How do immigrants with multiple sources of identity deal with the identity tensions that arise from misidentification within the workplace? In order to answer this question, we reposition two under-researched self-presentational identity work strategies - covering and accenting - as particular types of intersectional identity work. Adopting a minoritarian perspective, we apply this framework to an autoethnographic study of a non-white business scholar's identity work. To the extent that covering and accenting allow the scholar to draw identity resources from non-threatening and widely available social identities, we find that this work enables him to avoid being discredited in the eyes …

This paper reports on a study testing whether and how the use of effectuation and causation logics influences deliberate practice in businesses started by microfinance borrowers ("micro-entrepreneurs") in Sri Lanka. Using mixed methods, we surveyed clients of a large Sri Lankan microfinance institution and deepened findings from the survey through 24 interviews. In this way, we identified specific patterns of relationships between principles of the two logics and five elements of deliberate practice identified in the expertise literature from cognitive science. We found that both effectual and causal logics (but not effectuation alone) facilitate deliberate practice, an important result since …

Faculty of Business - Papers (Archive)
This study aims to test green accounting which is moderated by harmonious culture (green culture) in building a green reputation of a hotel. Green accounting activities consisted of environmental awareness, environmental involvement, and environmental reporting. The concept of harmonious culture emphasises the harmonisation with God, human being, and the environment to reach happiness. The implementation of the two variables legitimates a green hotel, and therefore acts as a signal for consumers to help in hotel selection. Quantitative analysis with Partial Least Square (PLS) method was used to process data collected through questionnaires. Sampling was conducted using purposive sampling with criteria …

Employee Voice In A Semi‐Rural Hospital: Impact Of Resourcing, Decision‐Making And Culture, Shamika Almeida, Elizabeth Frino, Marianna Milosavljevic
Faculty of Business - Papers (Archive)
The purpose of this paper is to understand current employee voice arrangements within a semi‐rural hospital and the implications for the engagement of healthcare professionals. The Job Demands‐Resources (JDR) model is used to explore how organisational mechanisms (resourcing, decision‐making processes and culture) provide a voice for staff. We adopt a single case study approach using in‐depth interviews with healthcare professionals in a semi‐rural public hospital in Australia. The study found that the semi‐rural context, characterised by high levels of centralised decision‐making and resourcing and low levels of confidentiality and anonymity, has limited employee voice and the ability for staff to …
The What And How Of Family Business Paradox: Literature-Inspired Distillations And Directions, Mary Barrett, Ken Moores
The What And How Of Family Business Paradox: Literature-Inspired Distillations And Directions, Mary Barrett, Ken Moores
Faculty of Business - Papers (Archive)
The purpose of this article is to review and comment on the literature on family business paradox against the backdrop of Moores and Barrett's 4Ls learning framework. This framework outlined the learning paradoxes, priorities and pathways that successful family business CEOs identified and coped with in their learning journeys. A 'what and how' theme emerges from our literature review (203 items) where we identify both confirmations and deficiencies in the 4Ls framework - deficiencies that suggest future research opportunities. Research directions are distilled in the form of questions that extend the 4Ls by enhancing the model both within it and …
A Toilet Paper Run Is Like A Bank Run. The Economic Fixes Are About The Same, Alfredo R. Paloyo
A Toilet Paper Run Is Like A Bank Run. The Economic Fixes Are About The Same, Alfredo R. Paloyo
Faculty of Business - Papers (Archive)
Panic buying knows no borders. Shoppers in Australia, Japan, Hong Kong and the United States have caught toilet paper fever on the back of the COVID-19 coronavirus. Shop shelves are being emptied as quickly as they can be stocked. This panic buying is the result of the fear of missing out. It’s a phenomenon of consumer behaviour similar to what happens when there is a run on banks. A bank run occurs when depositors of a bank withdraw cash because they believe it might collapse. What we’re seeing now is a toilet-paper run.
Effect Of Corporate Tax Avoidance Activities On Firm Bankruptcy Risk, Anirudh Dhawan, Liangbo Ma, Maria H. Kim
Effect Of Corporate Tax Avoidance Activities On Firm Bankruptcy Risk, Anirudh Dhawan, Liangbo Ma, Maria H. Kim
Faculty of Business - Papers (Archive)
Corporate tax avoidance has been shown to raise the cost of bank debt and lower credit and bond ratings. However, it is unclear whether tax avoidance actually increases a firm’s bankruptcy risk or whether it is just viewed negatively by banks and rating agencies. We find that firms engaging in tax avoidance and firms that are thinly capitalized face higher bankruptcy risk. To account for endogeneity and functional form misspecification, we verify our results using instrumental variable and propensity score matching methods. Our findings are consistent with the view that tax avoidance is a risk-enhancing activity.

Official Channels, Brian Martin
Official Channels, Brian Martin
Faculty of Arts, Social Sciences and Humanities - Papers
Official channels are things like grievance procedures, ombudsmen and courts. They are supposed to resolve problems and provide justice. However, trust in official channels can be misplaced: in many cases they may give only an illusion of a solution. In Official Channels, Brian Martin tells what he has learned about formal procedures set up to deal with problems associated with whistleblowing, sexual harassment, plagiarism, Wikipedia and other issues. He says it is unwise to put too much reliance on official channels and that more emphasis should be put on developing skills, changing cultures and exploring alternatives.

Economic Cognitive Institutions, Enrico Petracca, Shaun Gallagher
Faculty of Law, Humanities and the Arts - Papers (Archive)
Copyright © Millennium Economics Ltd 2020. This paper introduces the notion of 'cognitive' institution and discusses its relevance to institutional economics. Cognitive institutions are conceptually founded on the philosophy of mind notion of extended mind, broadened to also include the distinctly social, institutional, and normative dimensions. Cognitive institutions are defined as institutions that not just allow agents to perform certain cognitive processes in the social domain but, more importantly, without which some of the agents' cognitive processes would not exist or even be possible. The externalist point of view of the extended mind has already had some influence in institutional …

Electrical Stimulation-Induced Osteogenesis Of Human Adipose Derived Stem Cells Using A Conductive Graphene-Cellulose Scaffold, Jianfeng Li, Xiao Liu, Jeremy Micah Crook, Gordon G. Wallace
Australian Institute for Innovative Materials - Papers
The versatile properties of graphene-based materials are enabling various tissue regeneration, towards meeting an ever increasing demand for replacement tissues due to injury through trauma and disease. In particular, an innate ability for graphene to promote osteogenic differentiation of stem cells, combined with the potential to enhance the biological activity of cells through electrical stimulation (ES) using graphene, supports its use for osteoinduction or reconstruction. In this paper, we describe a miniaturized graphene-cellulose (G-C) scaffold-based device that incorporates electroactive G-C 'paper' within a polystyrene chamber for concomitant cell culture and ES. The G-C electrodes possessed lower impedance and higher charge …

EBSD in combination with aberration-corrected STEM is used to study the interfacial layer forming at Ni electrode - PbTe thermoelectric material interfaces. Contrary to previous studies, both orthorhombic and monoclinic phases are identified within the interfacial layer. EBSD and STEM data at interphase boundaries demonstrate an approximately smooth transition from orthorhombic to monoclinic phase with almost no crystal defects due to the small differences in lattice parameters and the prevalence of one of two previously unknown orientation relationships between the phases. Moreover, the presence of special boundaries resulting in orientation domains within both phases throughout the interfacial nickel telluride layer …

Australian Institute for Innovative Materials - Papers
Materials with protein resistant properties are increasingly sought after for their potential application as low-fouling surface coatings. Hydrophilic coatings with improved resistance to protein fouling have been prepared from zwitterionic carboxybetaine (CB) functionalized silica nanoparticles (SiNPs). The authors report three methods of coating preparation via direct tethering of CB to predeposited particle films, a two-step surface functionalization process, and deposition of CB functionalized particle dispersions. The pH at which aqueous CB solutions were prepared and reacted to SiNPs was found to drastically influence the mechanism of CB attachment and affect the protein resistance of the resultant coatings. Depending on the …

This journal is The Royal Society of Chemistry. Tin-based anode materials have aroused interest due to their high capacities. Nevertheless, the volume expansion problem during lithium insertion/extraction processes has severely hindered their practical application. In particular, nano-micro hierarchical structure is attractive with the integrated advantages of nano-effect and high thermal stability of the microstructure. Herein, hierarchical Sn/SnO nanosheets assembled by carbon-coated hollow nanospheres were successfully synthesized by a facile glucose-assisted hydrothermal method, in which the glucose served as both morphology-control agent and carbon source. The hierarchical Sn/SnO nanosheets exhibit excellent electrochemical performances owing to the unique configuration and carbon coating. …

Australian Institute for Innovative Materials - Papers
© 2020 Author(s). We report the experimental observation of the refraction and reflection of propagating magnetostatic spin waves crossing a 90° domain wall (DW). Time-resolved magneto-optical imaging was used to observe the propagation dynamics of magnetostatic spin waves. Due to the magnetization rotation across such a DW, the dispersion relation of magnetostatic spin waves rotates by 90°. This results in a change in the propagation dynamics of spin waves on both sides of the DW. We observed the refraction and reflection of magnetostatic spin waves at the DW and reveal their characteristics that include negative refraction. The incident-angle dependence of …

Australian Institute for Innovative Materials - Papers
We study, in the absence of a magnetic field, the stability of skyrmions in a disk-shaped ferromagnetic multilayer in the presence of locally pinned spins at the edge. This particular boundary condition suppresses the formation of helical states yet enhances the stabilization of states with rotational symmetry, such as Neél skyrmions. Numerical simulation shows that the size of the disk is a viable parameter to control the creation and annihilation of skyrmionic states. We also find that the demagnetization field renormalizes the Dzyaloshinskii-Moriya interaction. This study opens an alternative avenue to the generation, stabilization, and control of magnetic skyrmions in …

© 2020 Elsevier B.V. Thin films of polypyrrole (PPy) containing nano-Ni ('nano-Ni’) (as catalyst) and reduced graphene oxide (rGO) (as conductor) have been studied as (photo)electrocatalysts of the oxygen (O2)-evolution reaction (OER) (at 0.8 V vs Ag/AgCl, in 0.2M Na2SO4, pH 12) and the hydrogen (H2)-evolution reaction (HER) (at -0.75 V vs Ag/AgCl, in 0.05M H2SO4/0.2M Na2SO4) under light illumination of 0.25 sun. The above conditions were the most favorable for O2/H2-evolution under which the PPy and/or the nano-Ni constituents were not degraded. The industry benchmark catalyst, bare Pt, generated 0.15 mA/cm2 for O2-evolution and 2.2 mA/cm2 for H2-evolution under …
