Functional traits determine interactions between plants and pollinators, and to increase pollination efficiency, many plants have evolved traits to attract specific pollinator groups. However, biogeographical setting may influence trait evolution and biotic interactions. For instance, plants pollinated by hummingbirds often have ornithophilous traits, that is, flowers with elongated corollas, dilute nectar and red colours, but—due to colonization history, depauperate biotas and unstable environmental conditions—it might be disadvantageous for species to rely on mutualistic partners with specific functional traits on oceanic islands. Hummingbird-visited plants on islands are thus expected to have fewer ornithophilous traits and be functionally less diverse in their …

The Persistence Of Benefit Cliffs: A Behavioral Look At A Policy Problem, Vladimir Snurenco

University Faculty Publications and Creative Works

Benefit cliffs—where earning slightly more leads to losing more in government support—are often treated as technical glitches fixable through better formulas. But this article argues that the real problem isn't just economic—it's psychological. Drawing on behavioral economics and lived experience, the piece explores how fear, loss aversion, and system complexity keep low-income Americans trapped—even when policy fixes say they should be better off. Until policymakers account for how people actually feel and behave, benefit cliffs will persist not just on paper, but in real life

Post-Anthropocene Provocations: Human-Sized Scholars’ Rocks, Cronenbergian Flesh Caves And Zen Garden Design Cues For A Future Proof Re(Image)Ining, Brenton Rossow, Darren Tynan

Research outputs 2022 to 2026

This research explores concertinaing past, present and future interventional creative and pedagogical practices to address the challenges of the Post-Anthropocene era. We argue that the Post-Anthropocene is marked by biotechnological entanglements, environmental violence and digital overstimulation. The discussions herein critique a hyperattentive achievement society characterised by a scattering of attention, a near-constant screen-mediated stream of digital material and tasks and the commodification of leisure time. Enlisting Byung-Chul Han’s concept of hyperattention and themes and motifs from David Cronenberg’s films, the authors propose “FUTURE PROOF re(image)ining” as a collaborative Cli-Fi narrative concept. The project reimagines objects from an initial art installation …

Distinctive Transpassivation Behavior And Characteristics Of Passive Films Of Laser Powder Bed Fusion Produced And Annealed Ti–6al–4v In Hank's Solution, Yi Fan Zhang, Liang Yu Chen, Ze Xin Wang, Hong Yu Yang, Maksym Bobrov, Dobuvyy Oleksandr, Yong Liu, Lai Chang Zhang

Research outputs 2022 to 2026

Passivated Ti alloys typically demonstrate enhanced corrosion resistance due to the formation of passive films. Intriguingly, in comparison to the annealed Ti–6Al–4V, laser powder bed fusion (LPBF) produced Ti–6Al–4V exhibits significantly attenuated transpassivation behavior in Hank's solution. This work investigated the electrochemical responses of both samples before and after the transpassivation region to illustrate the underlying mechanism for the phenomenon. In the passivation region, both samples displayed analogous passivation behavior, with the annealed and LPBF-produced Ti–6Al–4V having the current densities of 6.64 × 10⁻⁶ and 8.14 × 10⁻⁶ A cm⁻² at 1 V, respectively. Between 1.5 V …

Descending Asymmetry In Proximate, Mobile And Digital Care: Chinese Older People Grandparenting Across Distance Within China And Overseas, Catriona Stevens, Rachel Murphy, Yu Huang, Loretta Baldassar

Research outputs 2022 to 2026

This article juxtaposes cases of grandparents who provide care for their grandchildren in two broad types of migrant families: (1) families where some members have migrated from the Chinese countryside to larger cities and (2) families where some members have migrated from China to Australia. By examining the proximate, mobile and digital forms of their grandparenting care labour, this article demonstrates the surprising durability and stability of care repertoires across distance and class. Despite the great differences of their migration geographies and family resources, these families nonetheless all demonstrate remarkably similar repertoires of caregiving articulated with reference to similar cultural …
