title: A blockchain-enabled framework for sharing logistics resources during emergency operations

authors: L'Hermitte, Cécile

subjects: blockchain

abstract: This study presents conceptual research designed to assess how the sharing economy concept can be leveraged to increase the participation of commercial organisations, such as retailers and transporters, in disaster relief operations. Drawing on social exchange theory, the academic literature on the sharing economy and blockchain, as well as existing resource-sharing practices in commercial and humanitarian logistics, the study develops a theoretical framework for analysing the structure, benefits, and prerequisites of a logistics-sharing system in emergency response. In addition, it proposes to utilise the blockchain distributed ledger technology-a shared data platform that enables authenticated communication and the widespread sharing of real-time information-to facilitate interactions and enhance trust between emergency responders and commercial organisations. It is argued that using commercial logistics resources, including emergency supplies, transport capacity, and storage space, has the potential to improve the mobilisation and deployment of urgently needed relief items and augment the flexibility of emergency response.

title: Structural and functional characterization of a promiscuous feruloyl esterase (Est1E) from the rumen bacterium Butyrivibrio proteoclasticus

authors: Goldston, David C.

subjects: rumen

abstract: The release of polysaccharide from the plant cell wall is a key process to release the stored energy from plant biomass. Within the ruminant digestive system, a host of commensal microorganisms speed the breakdown of plant cell matter releasing fermentable sugars. The presence of phenolic compounds, most notably ferulic acid (FA), esterified within the cell wall is thought to pose a significant impediment to the degradation of the plant cell wall. The structure of a FA esterase from the ruminant bacterium Butyrivibrio proteoclasticus has been determined in two different space groups, in both the apo-form, and the ligand bound form with FA located in the active site. The structure reveals a new lid domain that has no structural homologues in the PDB. The flexibility of the lid domain is evident by the presence of three different conformations adopted by different molecules in the crystals. In the FA-bound structures, these conformations show sequential binding and closing of the lid domain over the substrate. Enzymatic activity assays demonstrate a broad activity against plant-derived hemicellulose, releasing at least four aromatic compounds including FA, coumaric acid, coumarin-3-carboxylic acid, and cinnamic acid. The rumen is a complex ecosystem that efficiently degrades plant biomass and the genome of B. proteoclasticus contains greater than 130 enzymes, which are potentially involved in this process of which Est1E is the first to be well characterized.

title: Planning for the protection and enhancement of marine environments' wellbeing

authors: Barnsdall, Aaron

subjects: marine

abstract: The wellbeing of marine environments has a direct relationship with the types of whenua (land, placenta) use and management practices that go from the mountains to the sea. In Aotearoa, activities that are carried out in this land-marine interface, including those related to Nature-based Solutions (NbSs), are regulated by national, regional, and district policies (e.g., New Zealand Coastal Policy Statement, regional plans, and district plans). However, due to its novel character, not all current policies account for the realisation of NbSs nor are NbSs’ potential for addressing the wellbeing of our marine environments well understood.

This dissertation focuses on Tauranga Moana (the seas of Tauranga) as the chosen locality for the case study area, to:

i) investigate how the Ngapeke 7 Trust’s community participants in the Ngāti Pūkenga area of Tauranga Moana understand and value NbSs for addressing the wellbeing of their marine systems; and,
ii) review current planning policies and mechanisms to identify barriers, enablers, and gaps that support or hinder the implementation of NbSs in Tauranga Moana, observing through a Kaupapa Māori lens.

Findings emphasize that integrating mātauranga Māori and Māori Ecological Knowledge (MEK) with scientific knowledge offers a holistic approach to environmental management, enhancing decision-making, education, and policy. Key Māori values, including whakapapa, mauri, and kaitiakitanga, are central to this approach.

The research identifies gaps in policies regarding NbS realization and a need for greater understanding of NbS potential and Māori perspectives. Implications include the necessity of integrating MEK into environmental practices and policies, and the value of NbSs for effective and equitable environmental outcomes. Limitations include sample size and scope, which focused on the Ngapeke 7 block. This research contributes valuable insights for environmental planning and management by centring mātauranga Māori and values in NbS implementation for marine health.
