title: Storing RDF as a Graph

authors: Bönström, Valerie

subjects: computer science

abstract: RDF is the first W3C standard for enriching information resources of the Web with detailed meta data. The semantics of RDF data is defined using a RDF schema. The most expressive language for querying RDF is RQL, which enables querying of semantics. In order to support RQL, a RDF storage system has to map the RDF graph model onto its storage structure. Several storage systems for RDF data have been developed, which store the RDF data as triples in a relational database. To evaluate an RQL query on those triple structures, the graph model has to be rebuilt from the triples.
In this paper, we presented a new approach to store RDF data as a graph in a object-oriented database. Our approach avoids the costly rebuilding of the graph and efficiently queries the storage structure directly. The advantages of our approach have been shown by performance test on our prototype implementation OO-Store.

title: From chaos to cohesion - complexity in tourism structures: An analysis of New Zealand's regional tourism organizations

authors: Zahra, Anne Louise

subjects: chaos

abstract: This paper discusses chaos theory and provides a brief description of chaos and complexity theory. It notes past applications in tourism research with specific reference to the work of Russell and Faulkner relating to Australia's Gold Coast. In this paper, the concept is discussed with reference to regional tourism organizations in New Zealand. Both cases provide examples of complexity, attractors and dampeners, and feedback loops that limit change. It is suggested that one important contribution of chaos and complexity theory is that it provides a language to help identify the components of, and change within, a social system. The paper concludes that inherent in a complex system lies the notion that truly complex social phenomena embrace the linear, stable and predictable along with change, the dynamic, new, and unpredictable and even symbolic meaning.

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.
