title: An investigation of wearable and IoT technology for health applications: a user centered approach

authors: Shi, Yigang

abstract: The convergence of wearable technologies and the Internet of Things (IoT) has opened new possibilities for health monitoring and older adults care. However, existing systems remain fragmented, often lack interoperability, and tend to overlook the unique usability needs of older adults. This research investigates how a user-centered approach can inform the design and development of a Unified Wearable Device Framework (UWDF) to enhance integration, accessibility, and data visualization across heterogeneous IoT devices. Drawing on qualitative research involving older adults, caregivers, healthcare professionals, and technical personnel, the study identifies key design requirements and develops a working prototype of the UWDF platform. The framework emphasizes simplicity, modularity, and human-centered computing (HCC) principles. Usability testing demonstrates that the platform improves ease of interaction, supports personalized health monitoring, and facilitates caregiver engagement. The research contributes both a practical solution for managing diverse wearable health devices and a methodological reference for designing inclusive healthcare technologies that support aging-in-place.

title: Delivering on sustainability's global and local orientation

authors: Collins, Eva Marie

subjects: New Zealand

abstract: A sustainability instructor takes her graduate-level sustainability class to an eco-village on an island off of Auckland, New Zealand. The students have the opportunity to make mud bricks for homes, visit houses powered "off the grid" from solar and wind energy, and tour community gardens that provide fresh fruit and vegetables. Rain water is collected from roofs for use in the homes. At the end of the day, several New Zealand students approach the instructor and enthuse about how inspired they are by this alternative lifestyle. Two international students also approach the instructor; one student is from China and the other from Tajikistan. And although they approach the instructor separately, they have the same message: "This is how we live at home. We don't want to live this way. We want to live the way you do here in New Zealand."

title: Monitoring te mana o te wai: Intergrating an indigenous cultural health index with conventional biomonitoring tools for improved freshwater management

authors: Edgecombe, Shana Jade Te Iaa Tarere

subjects: Freshwater

abstract: Globally, there are universal efforts to quantify and address human impacts on ecosystems. In particular, changes in land use and river regulation have led to drastic declines in stream and river ecosystem health. These human impacts are driving the global freshwater biodiversity crisis and degrade ecosystem services provided by aquatic habitats. In Aotearoa New Zealand there is widespread concern about the state of our Nation’s freshwater ecosystems. Coupled with a renaissance in Māori culture, there has been a drive to develop indicators that help articulate cultural values, assess ecosystem health from a cultural perspective, and provide greater agency for Māori in environmental monitoring and management. In my thesis, I sought to integrate an established cultural monitoring framework with conventional biomonitoring tools for improved freshwater management. I hypothesized that using a suite of monitoring approaches would help detect the impacts of human land use on stream ecosystem health, and that cultural indicators would be consistent with conventional measures in diagnosing land use impacts. I also hypothesized that there could be discrepancies between cultural monitoring and conventional approaches, as each represent different perspectives and ways of knowing streams and rivers. 
To test my hypotheses, I selected ten stream sites across the catchment of the Kuratau River, a major tributary of Lake Taupō. Based on River Environment Classification land cover types, I used a balanced study design with five sites draining indigenous forest, and five sites draining pastoral land. I measured key stream physicochemical properties and collected water samples for determination of nutrient concentration and faecal coliform counts. I also characterised instream and riparian habitat. I collected benthic macroinvertebrate samples and sampled water for environmental DNA (eDNA) to assess different facets of biodiversity. I measured decomposition using the Cotton Strip Assay and quantified periphyton biomass using a portable fluorometer. In combination with these approaches, I also used a Cultural Health Index, an established cultural monitoring framework that assesses three components: customary significance, taonga species/mahinga kai (food gathering), and the Cultural Stream Health Measure (CSHM) to assess identified attributes for stream health.
I found that pastoral land uses lead to a decline in stream ecosystem health when compared to sites draining indigenous forest. Pastoral sites had higher specific conductivity and concentrations of total nitrogen and nitrate. Habitat variables changed, with increased sedimentation and more degraded riparian zones in pastoral streams. Decomposition rates as measured by the cotton strip assay increased in the pasture sites, which was likely a response to increased nutrient availability. There were shifts in macroinvertebrate composition, with key indicator taxa for Indigenous forest sites including pollution-sensitive mayflies and stoneflies. Total taxa, EPT (Ephemeroptera, Plecoptera, Trichoptera), and aquatic insect richness all significantly declined in pastoral sites. Increases in primary production were less pronounced, but did increase alongside abundances of grazing caddisflies and snails in the sites draining pastoral catchments. 
The Cultural Health Index indicated that sites in the Kuratau River catchment had customary and mahinga kai values. CSHM responded negatively to pastoral land uses, and the effect size it described was congruent with other responses. The CSHM was strongly correlated with an indicator of riparian habitat condition (the Riparian Condition Index) and had weak negative correlations with sedimentation and stream temperatures. The CSHM was not correlated with macroinvertebrate indices, which may have been because of the relatively few sites sampled, the narrow impact gradient in the Kuratau catchment, and the lack of temporal replication. However, cultural monitoring approaches should be seen to complement conventional environmental monitoring methods for assessing freshwater and not be expected to duplicate them. The strength of the Cultural Health Index approach comes from establishing Māori agency to assess the environment through a Te Ao Māori lens, and to support and foster inclusion for tangata whenua epistemologies in environmental monitoring and resource management. Future research should consider greater hapū involvement and further explore the mechanisms driving changes in stream health and biodiversity.
