Decoding emotional signatures of ethical ads : an analysis of actor‐viewer synchrony.
No full textWe examine whether ethical advertisements differ from conventional ads in their on‐screen emotional signatures and whether those signatures transfer to actor‐viewer synchrony. Study 1 analyses 138 professionally produced YouTube ads using Automated Facial Expression Recognition (AFER) and Convolutional Neural Networks (CNN) to quantify actor‐displayed basic emotions and their links to exposure‐adjusted engagement (comments and likes per 1000 views per day since release). Study 2 then measures viewers' facial responses while watching the same ads, showing that actor emotion peaks precede viewer peaks by fractions of a second and add incremental prediction for comment versus like intention. Across the two studies, we observe that ethical ads exhibit heavier moral‐diagnostic emotions and lighter happiness/neutrality on screen; moral peaks align more closely with discussion (comments), and happiness aligns more closely with quick approval (likes). We additionally specify and operationalise moral‐affect congruence and test whether congruence explains engagement beyond emotion main effects. We temper the observed findings by discussing boundary conditions (e.g., shot scale, occlusion). Finally, both theoretical and practical implications for creative design are outlined. The findings advance consumer research by reframing emotion in ethical advertising as a temporal and relational mechanism of moral persuasion, where short, congruent emotional peaks shape how audiences publicly engage. Practically, the results demonstrate how emotional timing, congruence and facial legibility can be deliberately designed to shift audiences from passive approval toward reflective participation, offering actionable guidance for ethical creative strategy and evaluation
Metallic MoB2 as a cocatalyst on CdS via EDTA-2Na chelation enabling efficient noble-metal-free photocatalytic H2 production via Schottky heterojunction
No full textThe excessive reliance on fossil fuels has triggered severe environmental crises, necessitating the exploration of sustainable and clean energy alternatives. Photocatalytic hydrogen evolution represents a promising technology, with cadmium sulfide (CdS) being a prominent visible-light-responsive semiconductor. However, its practical application is hampered by rapid charge carrier recombination. Constructing heterojunctions, particularly Schottky junctions with metallic cocatalysts, is an effective strategy to enhance charge separation, yet the high cost of noble metals remains a bottleneck. To address this, we report a novel and cost-effective photocatalytic system. Herein, a noble-metal-free Schottky heterojunction photocatalyst composed of metallic molybdenum diboride (MoB2) and CdS was successfully constructed via interface engineering using EDTA-2Na as a complexing agent. The optimized 12MoB2/CdS composite exhibited a dramatically enhanced photocatalytic H₂ evolution rate of 14035.8 μmol⋅g⁻¹⋅h⁻¹ under visible light irradiation, which is approximately 29 times and 66 times higher than that of CdS and unmodified CdS (CdS-p), respectively. The comparison demonstrated that EDTA-2Na acted as an effective interfacial modifier, which can significantly boost the photocatalytic H₂ evolution rate. The significant improvement demonstrated the effectiveness of employing a highly active non-precious metal boride and optimizing its integration with CdS. Comprehensive characterization and density functional theory (DFT) calculations revealed that the built-in electric field at the MoB₂/CdS interface efficiently drove the transfer of photogenerated electrons from CdS to MoB₂, significantly suppressing charge recombination. Through a Schottky heterojunction strategy utilizing metallic borides and interface engineering, this work achieves excellent photocatalytic performance, thereby advancing the development of efficient and economical noble-metal-free photocatalysts for solar hydrogen evolution

More than just screen time : perspectives of underserved rangatahi on the positive role of digital media and technology.
No full textThis study explores the positive role digital devices play in the lives of underserved Māori, Pacific, Deaf, and Rainbow rangatahi aged 12 to 15 in Aotearoa. While public discourse often emphasises the risks associated with digital engagement, emerging research highlights that cellphones, television, and video consoles can also support wellbeing when used in meaningful and intentional ways. This qualitative study examines how young people understand the benefits of their everyday media use, focusing on emotional regulation, social connection, and functional support in daily life. Drawing on pre-existing focus group data from the Rangatahi and Media project, reflexive thematic analysis was used to identify patterns in how adolescents describe the value of digital engagement within their relationships, routines and sense of identity. Three themes were developed that capture how digital devices support wellbeing by helping young people feel good (emotional regulation and enjoyment), stay connected (relationships, belonging, and identity), and navigate everyday life (learning, organisation, and practical support). The findings offer a more balanced understanding of early adolescent digital engagement and highlight the importance of culturally responsive, accessible and strengths-based approaches in discussions of youth wellbeing. These insights contribute to more informed policy, educational practice and support systems that recognise the diverse ways digital devices can enhance the lives of rangatahi
Medium access control for collision-free flight in UAV formations.
No full textThe deployment of Unmanned Aerial Vehicles (UAVs) in autonomous
formations requires accurate and timely communication of safety
information. To achieve this, there is a need for a communication
protocol that supports the timely and successful transfer of safety
information between UAVs. This thesis focuses on the unacknowledged
local broadcast of safety data that is periodically sent from
each UAV to the other UAVs in close physical proximity. This is
addressed using a Time Division Multiple Access (TDMA)-type MAC
protocol.
This thesis proposes three TDMA-based MAC protocols for UAVs
in rigid formations, each addressing different network topologies. In
rigid formations, the relative positions of the UAVs do not change
throughout deployment.
The proposed protocol designs in this thesis focus on overcoming
two limitations of traditional TDMA: scalability and a single point of
failure. Scalability refers to the need for each device to be allocated
to a unique time slot. A single point of failure refers to reliance on a
centralized controller.
The first protocol, a centralized spatial reuse scheme, serves as a
benchmark. With spatial reuse, multiple UAVs can be allocated to
the same time slot. This protocol demonstrates the improvements
achieved through utilizing spatial reuse compared to a traditional
TDMA scheme in a specific formation deployment. It addresses the
issue of scalability but is reliant on a centralized controller.
The second protocol, Distributed Assignment and Resolution of Time slots (D-ART), supports allocation without a centralized
controller in single-hop scenarios. This protocol is designed for
a fully-connected UAV formation and provides distributed superframe
adaption and self-allocation for single-hop communication. It
addresses the single-point-of-failure issue but each UAV must be
allocated to a unique time slot.
The final protocol, Distributed Self-allocated Time slot Reuse (DSTR),
extends these capabilities to multi-hop scenarios. It addresses
both the scalability and single-point-of-failure limitations, and can
be used in both single-hop and multi-hop scenarios.
These proposed protocols address the essential task of communicating
safety information in rigid UAV formations with different
network topologies, enabling collision-free deployment of the formation. This is an important step for improving the safety and
practicality of UAV formations in application scenarios that span a
range of industries

Critical Report of AI’s Future Potential for Transforming Environmental Legislation for Environment Canterbury. Report prepared part of the GEOG309 Research for Resilient Communities and Environments course, University of Canterbury, 2025.
No full textThis report details our research process and how we applied AI to simplify and solve hypothetical resource consent conditions in accordance with Environment Canterbury (ECan) data sets and Land and Water Regional Plan (LWRP) rules. Results from our AI agent were significant with room for further implementation and growth. This is important because the rationale of our research was to help prepare for Ecan’s upcoming shift towards a digital framework. Currently ECan works on a paper-based model which is rapidly becoming outdated. Consecutive National and Labour governments have agreed that changes in environmental planning are needed. (Bishop & Court, 2025) An update to the Resource Management Act is set to pass into law in mid-2026, giving ECan time to test new tools. (Ministry for the Environment, 2025) The end goal of all this research is to create a new model that will achieve better environmental outcomes. Shifting to a digital system will make it easier for applicants to answer questions like “What can I build here?" or “Have I done this right?” At the end of the day, the majority of people want to comply with their consent conditions. Incorporating AI will result in increased accessibility and usability, resulting in positive outcomes for the environmen
