A Scalable Sampling Approach for Artificial Intelligence-Based Alcohol Content Estimation in Movies
No full textIntroduction: The growing accessibility of movies through streaming platforms has expanded audience reach, but also increases exposure to alcohol portrayals, which is an established risk factor for alcohol use. Hence, estimating alcohol depictions is important yet challenging due to the time and labor involved. Artificial Intelligence offers a scalable solution for analysing movie frames; however, processing every frame of a full-length movie at 25 frames per second (fps) requires extensive computational resources. Thus, we aimed to test whether lower-frequency sampling would affect the accuracy of alcohol exposure estimates. Methods: We analysed 20 feature-length movies with varying known alcohol visibility and analysed each frame using zero-shot predictions from a LLaVA v1.6 model (accuracy = 95%) as our baseline. We applied uniform downsampling from 25 fps (full-framerate) to 1 fps and sparse interval sampling of 1 frame per N seconds (N = 1,2,…,10), measuring both alcohol-proportion estimates and execution time. To assess the sampling-induced error, we computed the difference score, as the difference between sampled and full-frame alcohol proportions. Results: A sampling frequency of 1 fps yielded an average difference score below 0.10 compared to the full-frame analysis, while reducing execution time by 25-fold. Error increased at sparser intervals, reaching a difference score of 0.46 at one frame per 10 s. Discussion and Conclusion: Reducing the sampling frequency from 25 to 1 fps resulted in only a minimal loss of accuracy but a substantial reduction in execution time. This finding supports 1 fps as a practical and scalable sampling frequency for large-scale movie alcohol exposure estimation.</p

Developing a Shared Ecosystem for Agricultural Education: A Community of Practice for Open Access Resources
No full textThis shared discussion proposed the formation of a Community of Practice (CoP) among Australian agriculture educators to shape the direction of an Open Educational Resource (OER).The session launched a survey to assess current gaps in learning resources, identify key barriers, and articulate current effective practices to model. The results of this survey will inform an OER project to collectively create a "living text" that can be rapidly updated to keep pace with changing practices in higher education and agricultural sciences. It will be hosted and coordinated in partnership with the La Trobe eBureau open education program.This discussion and survey was part of AgEd26, the 4th Symposium for Agricultural Educators. The symposium took place at the AgriBio building on La Trobe University's Bundoora campus in Melbourne on 3-4 February 2026. It was hosted by the Australian Council of Deans of Agriculture, La Trobe University, and University of Melbourne.</p

In Search of the Bricoleur Consumer: Conceptualizing and Measuring Bricolage in Fashion Consumption
No full textWe conceptualize consumer bricolage in fashion as everyday practices of assembling, adapting, and personalizing garments to express identity within resource-constrained contexts, and develop a validated, multidimensional scale to capture it. Across five studies, we specify the construct via qualitative inquiry, generate and screen items, and then use survey-based analyses to establish a reliable three-dimensional structure, along with convergent, discriminant, and predictive validity. The resulting scale is theoretically distinct from adjacent constructs (e.g., customization, need for uniqueness, co-creation, innovativeness) and exhibits the expected associations with fashion consciousness, as well as incremental links to fashion consciousness, identity distinctiveness, fashion innovativeness, and consumers' social media engagement. By clarifying the dimensions of consumer bricolage and providing a robust instrument, we advance research on consumer bricolage and self-expressive consumption, particularly in contexts where resourcefulness and identity signaling are intertwined. For managers, the scale supports segmentation and the design of personalization pathways (e.g., modular assortments, upcycling kits, community challenges) that cultivate brand-community engagement.</p

Ensuring Cybersecurity in Ports for Major Port States in Southeast Asia
No full textAs ports across Southeast Asia become more digitally integrated, cybersecurity has emerged as a critical maritime security challenge. Increasing reliance on IT, OT, and connected systems has expanded vulnerabilities at major regional ports, particularly along the Strait of Malacca, with potentially severe consequences for global supply chains. Addressing these risks requires coordinated regulatory approaches, harmonised standards, and strengthened public–private cooperation to enhance cyber resilience and protect critical port infrastructure.</p
