Communities of practice in the production and resourcing of fact-checking
No full textThis article considers the ways in which national and international institutional alliances and professional organizations form the basis of a collaborative approach to the resourcing, production, and distribution of fact-checks through a case study of CoronaCheck, the COVID-19 fact-checking project of Australia’s RMIT ABC Fact Check. In doing so, it builds on a theorization that conceives of journalism as a “community of practice.” Two themes emerge from attention to the conceptual framework, content analysis of CoronaCheck newsletters and interviews with fact-checkers and journalists. The first relates to the nexus between fact-checking communities of practice and the productive and collaborative networks that underpin their operation. The second builds on this to consider the structures, resources, and approaches that facilitate experimentation within the community. Taken together, the findings suggest that understanding the practices of international and inter-institutional collaboration in fact-checking efforts such as CoronaCheck is key to shedding light on how a subcommunity of journalism practice broadens its remit and reorients the concerns of the domain in response to change
Linking environment specific servant leadership with organizational environmental citizenship behavior: the roles of CSR and attachment anxiety
No full textThis paper aims to examine the mechanisms and boundary conditions that underlie the relationship between perceived environment specific servant leadership (ESSL) and perceived organizational environmental citizenship behavior (OECB). By drawing on the social exchange and social identity theories, we explore corporate social responsibility (CSR) as a mediator and attachment anxiety as a moderator of the ESSL-OECB relationship. The proposed relationships were examined by collecting data in two-waves through a survey of 359 employees and their supervisors working in various manufacturing-sector organizations. The data were analyzed through a bootstrapping test in structural equation modeling and the empirical results confirmed that CSR mediates the relationship between ESSL and OECB. However, attachment anxiety was found to moderate the indirect effects of ESSL on OECB via CSR such that the relationships were stronger for employees with high attachment anxiety in comparison to those with low attachment anxiety. The paper concludes with a discussion of the implications of this study's results for management theory and practice
Importance of residents’ perception of tourists in establishing a reciprocal resident-tourist relationship: An application of tourist attractiveness
No full textThis study was guided by the notion of tourist attractiveness to understand residents' perception of tourists in establishing a reciprocal resident-tourist relationship. To explore the concept of reciprocity and how it is associated with tourist attractiveness, this study adopted an exploratory sequential mixed-method approach in the context of Chinese tourists visiting Jeju Island, South Korea. Findings from semi-structured interviews indicate that residents' perception of reciprocity can be conceptualized and measured through the constructs of resident satisfaction and resident commitment. Further, structural equation modeling found that residents are more satisfied and likely to be committed to the relationship with tourists when these visitors are perceived as attractive partners. The results demonstrate a mechanism for explaining how the residents’ perceptions of tourists influence their satisfaction with tourists and intention to host, market, or attract them again in the future
Contextualising capabilities for public safety in undergraduate sustainability engineering education
No full textSustainability in university curricula remains important for equipping graduates from all disciplines with capabilities to respond to complex social, economic, and environmental challenges in their future professional roles. Situating sustainability learning within disciplinary contexts is needed for learners to apply sustainability theory to their future professions. Furthermore, developing capabilities is important to enable graduates to act in differing professional contexts. In response to these needs, this paper contextualises safety as part of sustainability in undergraduate engineering studies by exploring the complementarity between professional capabilities for safety in engineering and key capabilities found in sustainability education literature. The paper draws on findings from interviews with 41 pipeline engineers undertaken to build an understanding of differing views on engineering capabilities necessary for safety decision making. The results show synergies between safety and sustainability capabilities in the context of engineering practice and the opportunities to contextualise safety within sustainability in engineering education. From a safety perspective, given the expanding sustainable development agenda, there is an opportunity to increase education for public safety in engineering curricula within the scope of sustainability education and to shift learning from competencies to capabilities-based outcomes
Heritage child stars on Disney+: the liquidities of child stardom in the SVOD era
No full textDisney is a brand long associated with the production of family content and a continually replenished suite of child stars. The 2019 launch of Disney+ leveraged these heritage child stars in its tightly curated home page, stressing nostalgia and a wholesome brand image around the figure of the child. This article explores how the Disney+ interface aesthetics, catalogue organisation and other paratexts negotiate heritage child stars in the context of managing the Disney brand narrative in the streaming era. Streaming interfaces offer a new form of star ephemera, as former child stars are recontextualised under new thematic banners on Disney+. However, this careful curation on the Disney+ interface is ultimately unable to contain the instability of child stars as emblems of lost youth, a tension that becomes particularly evident in the case of Lindsay Lohan and Macaulay Culkin
Data mining: will first-year results predict the likelihood of completing subsequent units in accounting programs?
No full textThis study introduces data mining methods to accounting education scholarship to explore the relationship between accounting students’ current academic performance (grades), demographic information, pre-university entrance scores and predicted academic performance. It adopts a C4.5 classification algorithm based on decision-tree analysis to examine 640 accounting students enrolled in an undergraduate accounting program at an Australian university. A significant contribution of this study is improved prediction of academic performance and identification of characteristics of students deemed to be at risk. By partitioning students into sub-groups based on tertiary entrance scores and employing clustering of study units, this study facilitates a more nuanced understanding of predictor attributes. Key findings were the dominance of a cluster of second year units in predicting students’ later academic performance; that gender did not influence performance; and that performance in first year at university, rather than secondary school grades, was the most important predictor of subsequent academic performance
Probing the Extremes of Aesthetics: The Role of Typicality and Novelty in the Aesthetic Preference of Industrial Boilers
No full textThere is a long history of humans attempting to understand what drives aesthetic preference. One line of inquiry examines the effects of typicality and novelty on aesthetic responses to designed products. There is currently a wide support towards the ‘Most Advanced Yet Acceptable’ (MAYA) principle, and studies underpinning this have focused on everyday objects. Despite the differences in the function of everyday objects, what they all have in common is their visibility. This do not tell us whether the aesthetic processing will be the same when applied to less visible objects. A study was undertaken using industrial boilers as stimuli and conducted on 7-point Likert scales with participants from Australia and China. The results are unequivocal: novelty makes a medium contribution, while typicality makes a low contribution. This is inconsistent with the notion that typicality is a major determinant of aesthetic preference, suggesting that the current models of aesthetic preference need elaboration
Removal of heavy metals from wastewater using low-cost biochar prepared from jackfruit seed waste
No full textThe present study focuses on using jackfruit seed waste (JSW) for bioremediation of heavy toxic metals from water. The fruit is abundantly grown in India and Far East countries and produces myriad tons of seeds. A simple procedure is developed in the laboratory by thermally activating JSW by orthophosphoric acid at 500 °C. Surface morphology, porosity, and structural analyses of the resultant biochar were conducted. The activated biochar was applied for batch adsorption of several heavy metal ions: Fe(III), Cd(II), Cu(II), Pb(II), and Mn(VII) at pH 7. The average heavy metal uptake by activated JSW biochar is 76.4 mg g−1, 79.4 mg g−1, 97.9 mg g−1, 79.9 mg g−1, and 79.8 mg g−1 for Fe(III), Pb(II), Cu(II), Cd(II), and Mn(VII), respectively. The experimental conditions were optimized to remove heavy metals at neutral pH. The adsorption process was exothermic, and Langmuir and pseudo-second-order kinetic study models were best fitted. The observation was in close agreement with the experimental data. Thermal and structural characterization of biochar at post-adsorption analyses was conducted. The study has distinguished features of simplicity, cost-effectiveness, and viability compared to many of the literature-reported biomass waste.

Delivering evidence-based management services: rising to the challenge using design science
No full textEvidence-based management (EBMgt) concerns making complex managerial decisions by combining the decision maker’s knowledge and experience with scientific knowledge. A major obstacle to this practice is the lack of support. In this paper, we employ design science to develop an ensemble of conceptual, information and IT artefacts that support EBMgt. The approach is instantiated and validated in a case study using a combination of methods, including proof of concept, laboratory experiment, satisfaction survey, and focus groups. The proposed approach turns EBMgt into a repeatable practice, supported by reusable tools, and brings some degree of automation to the process. To our knowledge, EBMgt services have not yet been realised in a concrete manner, and not with concrete empirical results. Therefore, this study provides a first-of-a-kind demonstration and assessment of the viability of EBMgt services
Overview of hydrogen economy in Australia
No full textThe hydrogen economy is on the verge of expansion across the globe. Leading economies like Japan, South Korea, China, the United States of America, Germany, and Australia are steadily pushing for greater hydrogen integration into their energy systems. Australia's thrust on the hydrogen economy becomes prominent with clear strategic actions to enhance clean technology-based hydrogen production. The paper critically analyses Australia's strategies and policies to expand its hydrogen economy. The paper found that Australia fixed ambitious targets to increase hydrogen penetration in the domestic market and export to Japan, China, and South Korea. Australia's national hydrogen strategy emphasized creating a strong hydrogen value chain to capitalize on abundant renewable resources. This article affirms that Australia has enormous potential for cost-competitive green hydrogen production and export. Australia's cost-competitive green hydrogen production with modern supply chain infrastructure will offer competitive advantages over the other exporters. States/regions are trying to align their hydrogen policies and strategies along the lines of the national strategy. However, some concerns demand timely attention from the stakeholders. Australia should address multiple challenges, including a lack of investment, lower public awareness, and insufficient infrastructure to push hydrogen adoption in the domestic market. Further, Australia must utilize its strengths to take advantage of the emerging hydrogen markets in Japan, China, and South Korea
