title: The development of tools and guidelines for surfing resource management

authors: Atkin, Edward Anthony

subjects: Surf

abstract: Surfing is a mainstream pastime and competitive sport in many countries and provides a full range of economic, social, physical, and mental health benefits. Maintaining the integrity of surf breaks has proven to be a challenge, with a litany of degraded or destroyed surfing locations worldwide. This is attributed to a deficiency in expertise and experience in implementing surf science and management within governing authorities, associated consultants, or stakeholder groups; combined with a lack of value recognition and identification. This work considers how surf breaks as coastal resources could be better managed. 
A literature review of technical reports, published articles, statutory instruments, evidence, and consents, along with interactive stakeholder workshops and surveys to identify key considerations, are combined with complex numerical modelling and machine learning methods to develop tools for effective surf break management.
In Aotearoa New Zealand, a surf break is described in policy as having various geophysical components in the vicinity of locations where surfing takes place and the areas offshore. Given the wide range of benefits associated with surfing, and the complexities of managing a natural resource, albeit in some cases anthropologically modified, the term ‘surfing resource’ was established and defined as a major outcome of this work and as a step in the process of developing a set of Management Guidelines for Surfing Resources (the Guidelines). The Guidelines, which are a world first, consider what aspects of the environment are the most important to surfing resources management, provide direction, as implementable steps, to authorities and proponents of activities in the coastal environment that can impact surfing resources, and include identification and monitoring strategies as well as a novel risk assessment framework which is underpinned by a surf break’s sensitivity as a function of geomorphological composition.
The Guidelines are supported by research streams that required field data collection and monitoring system development, numerical modelling, and machine learning to improve our understanding of surf break functionality and/or better our management strategies. This work emphasises the role of bathymetric features outside the surf zone that contribute to surfing wave quality, and the value of establishing swell corridors for management purposes. An automated system has been developed to monitor the key surfing wave quality indicator of peel angle through both space and time.
Effective surfing resource management requires a holistic, inclusive, case-by-case approach, that may require cultural, social and geophysical assessment, which is best implemented proactively with the identification of surfing resources and the establishment of environmental baselines.

title: Secure voting in the cloud using homomorphic encryption and mobile agents

authors: Will, Mark Antony

abstract: While governments are transitioning to the cloud to leverage efficiency, transparency and accessibility advantages, public opinion - the backbone of democracy - is being left behind. Statistics show that traditional paper voting is failing to reach the technological-savvy generation, with voter turnout decreasing every election for many first-world countries. Remote electronic voting is a possible solution facilitator to this problem, but it still faces several security, privacy and accountability concerns. This paper introduces a practical application of partially homomorphic encryption to help address these challenges. We describe a cloud-based mobile electronic voting scheme, evaluating its security against a list of requirements, and benchmarking performance on the cloud and mobile devices. In order to protect voter privacy, we propose moving away from a public bulletin board so that no individual cipher votes are saved, while still allowing vote verification. As the majority of the security threats faced by electronic voting are from the underlying system, we also introduce the novel concept of using a dedicated hardware server for homomorphic tallying and decryption.

title: A path to lotions and potions: Ngāti te Maunga ahi kā use of rongoā for hapū wellbeing

authors: Diamond, Kiri

subjects: rongoā

abstract: The research aimed to determine the challenges and improvements required during the implementation of the rongoā programme. The rongoā programme was based on a papakāinga near a marae, in a semi-rural location with difficult access. Participatory action research and autoethnography methods were used with the ahi kā (local residence) to develop a programme that would fulfil the hapū ora (extended family wellbeing) goals.  The goals of the programme were: for the ahi kā to use rongoā (modalities of health) confidently for their wellbeing; consistently use a Facebook page to learn and share information and to develop a database of the local rongoā rākau (medicinal plant). The ahi kā identified a further question to ask Facebook members to understand what motivated their participation and a survey was conducted. The ahi kā also wanted to understand the local doctor’s view on rongoā and its context on health provision in their area. An interview was conducted and the survey and interview added to the understanding of what the ahi kā could do to improve theirs and the hapū whānau (group extended family) wellbeing.
The findings of the research highlighted the complexities that arise from conducting research in a bicultural space where a common understanding of cultural knowledge is assumed to be homogenous. A shared history with colonisation and religious beliefs brought to the forefront the multiplicity Māori work through to determine a shared hapū identity. Based on an understanding of Māori principle values and tikanga (ways of enacting values), as understood by ahi kā, transformed a programme of learning how to make lotions and potions for the ahi kā, into influencing hapū members to change their attitudes and behaviours to their environment and their wellbeing.
This research highlighted the role that ahi kā hold as keepers of cultural knowledge that is rooted in the papakāinga through ancestral links that informs the identity of a hapū. Learning how to use rongoā provided ahi kā a platform to learn a new skill while helping the hapū heal through connecting with the identity and land of the hapū they belong to.
