Sulfonated plantain-peel solid acid for FFA esterification pretreatment of waste cooking oil: synthesis, characterization, and RSM optimization
No full textThis is an open-access article distributed under the terms of the Creative Commons Attribution License.This study investigated the synthesis and application of a sulfonated heterogeneous solid acid catalyst derived from a ripe-unripe plantain peel mixture for the esterification of waste cooking oil (WCO). The catalyst was prepared by carbonizing the dried plantain peel mixture at 550 °C for 2 h before being sulfonated with concentrated sulfuric acid. Analytical techniques such as FTIR, SEM/EDX, XRD, XPS, and BET/BJH were used to characterize the developed catalyst. WCO esterification was modeled and optimized using a central composite design of response surface methodology. Characterization revealed that the synthesized catalyst is a crystalline material with dominant phases of K2Ca(SO4)2·H2O and K2SO4. BET surface area of 49.3 m2/g and average pore diameter of 6.15 nm demonstrated the mesoporous nature of the developed catalyst. FTIR, XPS, and XRD analyses confirmed the successful incorporation of sulfur-containing acidic groups, primarily –SO3H, on the surface of the catalyst. At the optimized conditions of 60 °C reaction temperature, 62 min reaction time, 10.8:1 methanol/WCO, and 3.5 wt% catalyst amount, the esterification achieved 90.5 ± 1.64 % FFA conversion. A possible esterification reaction mechanism was proposed. Reusability of the catalyst was successfully demonstrated after 5 reaction cycles, with a conversion of 76.4 %. The findings from this study highlight that the synthesized catalyst derived from plantain peel, is capable of serving as a solid-acid catalyst for pretreatment (FFA esterification) of WCO prior to base-catalyzed transesterificationCentre for Energy and InfrastructureDepartment of Chemical Engineering, Cape Peninsula University of Technology, Bellville Campus, Symphony Way, Bellville, Cape Town 7535, South AfricaHolmesglen InstituteDepartment of Petroleum and Gas Engineering, Baze University, Abuja, NigeriaDepartment of Chemical Engineering, Faculty of Engineering and Technology, University of Ilorin, Ilorin, Kwara State, Nigeri
How do perceptions of risk influence the adoption of electric motorcycles? A theory-based investigation considering the multidimensional nature of risk
No full textAbstract only. Item availability may be restricted.In low- and middle-income countries, electric motorcycles (EMs) are not generally well accepted in the community as many infrastructural, technological, and psychosocial barriers remain unaddressed. A greater understanding of adoption barriers perceived by motorcycle riders can help devise strategies, such as policy and behavioural change interventions, to increase the uptake of EMs. This study aimed to investigate the risk dimensions of EM adoption and integrate them into the Theory of Planned Behaviour to model users’ intention to adopt EMs. A multi-group analysis was also conducted to examine the moderating effect of demographic characteristics on the proposed model. The data were collected from two cities in Vietnam, making this one of the region’s first theory-based studies on the electrification of the transport system. The outcomes of the structural equation modeling affirmed that the psychosocial variables outlined in the Theory of Planned Behaviour (i.e., attitudes, perceived behavioural control, and social norms) and perceived risk significantly influence the behavioural intention to adopt EMs. These findings hold significance for policymakers and manufacturers as they provide valuable insights into the factors that can be targeted to enhance the adoption of EMs. This represents a crucial step towards advancing sustainability goals in low- and middle-income countries.Bachelor of Hospitality ManagementThe University of DanangHolmesglen InstituteNational Economics University, Hanoi, VietnamHuazhong University of Science and Technology, Wuhan 430074, ChinaDelft University of Technology, Jaffalaan 5, 2628 BX Delft, The Netherland
Escape Rooms prepare students with transferable skills for diverse work
No full textItem is not available from this repository. Please contact the author.The evolving landscape of Vocational education and training (VET) continues to ask more of students. Students are expected to be equipped with the skills and competencies required to perform tasks in the workforce, but are also expected to be critical thinkers, with time management skills, who can work in diverse teams and adapt to change. Current industry feedback suggests that students are not meeting these requirements, showing an opportunity for educational innovations to target these areas and develop the transferrable skills (sometimes known as soft skills, or work-readiness skills) of students.NursingHolmesglen InstituteAVETRA 2025Melbourn
Cancelled: how the cancellation of the 2026 Victoria Commonwealth Games signalled a shift in Australian sport
No full textOpen access.In July 2023, the Victorian Government cancelled the 2026
Victoria Commonwealth Games, breaking with four decades of pro
mega-event policy. This study examines how this unprecedented
decision — prompted by a multibillion-dollar budget blowout —
reflects shifting attitudes toward hosting sporting mega-events in
Victoria and Australia. Through historical analysis of Victoria’s
sports investments and cultural narratives, including Australia’s
‘cultural cringe’, we identify a transition from uncritical boosterism to
increased scrutiny of costs and benefits. Whereas mega-events were
long championed to bolster national identity and global standing,
today there is greater public and political willingness to question
their value. This shift suggests a maturing cultural perspective in
which sport’s role in national identity is being re-evaluated, and it
foreshadows heightened scrutiny for future events like the Brisbane
2032 Olympics.Sports Media and Sport Business DegreesHolmesglen InstituteMonash Universit
Storytelling Without Borders: the power of translated Australian literature
No full textItem is not available from this repository. Please contact the author.This presentation discusses the two facets of an interdisciplinary collaborative project. The Trove lists project celebrated its first anniversary in March 2025. It has a simple concept – advocating and promoting Australian work published in languages other than English to readers in and beyond Australia. Australian publications are windows to the soul of the nation. The project team creates languagespecific lists of translated Australian fiction and non-fiction on Trove, a free online library catalogue managed by the National Library of Australia (https://trove.nla.gov.au/). The project started with Australian fiction and non-fiction translated into Chinese and soon expanded
into 15 lists of translated children’s picturebooks.
Picturebooks are a staple of Australian public libraries and the cornerstone of the children’s collection. Picturebooks serve as a springboard for families and children to read, play, and learn through programs such as rhyme time, story time, and other school-holiday activities. In other words, a good collection of children’s picturebooks attracts young readers and their families to the local public libraries. In Australia, the children’s collection includes both English-language and multilingual publications. Our experience is that the multilingual publications frequently showcase works written and illustrated by overseas authors and artists. However, we do not necessarily have translated editions of popular Australian works. For example, we see a picturebook by Tarō Gomi (五味 太郎) in Japanese, but not Mem Fox’s The Possum Magic in Japanese.
It started with an inspiration – a Korean official website that celebrates Korean literature translated into multiple languages and published in the four corners of the world. An academic librarian (Website and Systems) suggested trying something similar for Australian literature. A project idea was then brought to the ALIA Multicultural Committee, and an academic in the School of Education joined the team. Sharing the same first language, Chinese, the team agreed to start small with fiction and non-fiction translated into Chinese. When the two Trove lists were published, a well-loved Australian children’s author suggested expanding the project to children’s literature, and this suggestion was taken on. The 2-person team soon grew to 9 (and growing). The number of translated Trove lists also expanded to 39. Within a year, the team collected more than 10,000 items of Australian works translated and published in 22 languages.
Translated Australian works provide multilingual windows to understanding Australian culture, and these translated works can be important for the multicultural communities. The team then utilised different dissemination venues (e.g. blogs, podcast, trade magazine, radio interview) to promote the use of these lists to diverse audiences. These lists can be used by librarians to inform collection acquisition, and educators to support multilingual learners and their families. Focusing on the lists of translated children’s picture books, the presentation will present an analysis of the Trove lists, and discuss the interdisciplinary collaboration behind the scenes, arguing that the Trove lists of translated Australian works can be used to reflect our cultural past, yet helping to shape our multicultural future.LibraryMacquarie UniversityHolmesglenRAILS 2025: Library and Information Research: Reflecting on the Past, Shaping the FutureCharles Sturt University Sydney Campus, North Sydney, Australia

Downsizing the Games: Brisbane’s cut-price Olympics
No full textAustralian sport is undergoing a period of downsizing following a long boom from the mid-1990s to the COVID era. Melbourne withdrew from hosting the Commonwealth Games due to cost, and Brisbane’s Olympic ambitions have faced similar challenges. Initially, under Annastacia Palaszczuk, Queensland planned a transformative 2032 Olympics centred on Brisbane, including a Gabba rebuild and new inner-city venues. However, the IOC’s push for modest, budget-conscious Games clashed with local ambitions. Palaszczuk resigned in 2023, and her successor Steven Miles scaled back plans, opting for the existing QSAC stadium and rejecting costly infrastructure proposals. Miles aligned with IOC reformer John Coates, who envisioned Brisbane as a model for downsized, sustainable Olympics. Yet in November 2024, the newly elected LNP government under David Crisafulli reversed course, scrapping QSAC and launching a 100-day review. The ongoing indecision reflects competing visions: developers and media seek a transformative Games, while the IOC advocates restraint. With limited infrastructure and rising costs, Brisbane’s Olympic future hangs in the balance—either as a model of fiscal discipline or a financial risk.Sports Media and Sport Business DegreesHolmesglen InstituteCentre for Sociocultural Spor and Olympic Research.

Enhancing data provenance in AI with blockchain technology: a comprehensive quality model
No full textItem is not available from this repository. Please contact the author.This study shows a new way to use blockchain to assess the quality of data in AI systems. Using the ISO/IEC 9126 software quality model as a starting point, we conduct a thorough study to find and explain the quality attributes that are most important for blockchain technology. To determine in how effectively blockchain technology works for AI data source, it depends upon number of quality attributes. We align quality attributes with ISO/IEC 9126 quality characteristics, such as Data Immutability, Decentralized Ownership, and Smart Contract Compliance, in order to better understand how blockchain technology works. Furthermore, we explore the potential implications and benefits of blockchain-based data provenance, such as enhanced security, transparency, and compliance with data regulations. Through this model, we highlight how blockchain technology can fill trust and reliability in AI systems, thereby fostering their broader adoption across diverse industries.Centre for Cyber Security and Digital Information TechnologyHolmesglen Institut
Accessibility is virtually inescapable: designing and creating an online escape room for all students
Full text linkThis presentation details the development of an online escape room “Virtually InescAPAble” that was designed as an engaging and interactive learning tool to support APA 7th referencing skill acquisition. Prior to designing the activity, we conducted a review of existing escape rooms created by academic libraries using LibWizard where we identified best practices and common challenges. Our focus became creating a fun and inclusive experience that supports the diverse backgrounds of our learners. The session highlights practical and reproducible strategies used to ensure increased accessibly as part of the creation of an online resource while maintaining the entertainment and challenge of the escape room format.LibraryHolmesglen InstituteALIA VET Libraries Australia Conference 2025onlin
