title: Development of wireless network planning software for rural community use

authors: Bartels, Samuel James

subjects: wireless

abstract: Rural New Zealand has poor access to broadband Internet. The CRCnet project at the University of Waikato identified point-to-point wireless technology as an appropriate solution, and built networks for rural communities.  The project identified viable solutions using low-cost wireless technologies and commodity hardware, allowing them to establish general construction guidelines for planning rural wireless networks. The CRCnet researchers speculated that these general construction guidelines had simplified the wireless network problem to a point at which it seemed feasible to embed the guidelines within a software tool. A significant observation by the CRCnet researchers was that community members are collectively aware of much of the local information that is required in the planning process. Bringing these two ideas together, this thesis hypothesises that a software tool could be designed to enable members of rural communities to plan their own wireless networks.

To investigate this hypothesis, a wireless network planning system (WiPlan) was developed. WiPlan includes a tutorial that takes the unique approach of teaching the user process rather than the detail of network planning. WiPlan was evaluated using a novel evaluation technique structured as a roleplaying game. The study design provided participants with local knowledge appropriate for their planning roles. In two trials, WiPlan was found to support participants in successfully planning feasible networks, soliciting local knowledge as needed throughout the planning process. Participants in both trials were able to use the techniques introduced by the tutorial while planning their wireless network and successfully plan feasible wireless networks within budget in both study trials. This thesis explores the feasibility of designing a wireless networking planning tool, that can assist members of rural communities with no expertise in wireless network planning, to plan a feasible network and provides reasonable evidence to support the claim that such a planning tool is feasible.

title: Identification of nest predators using continuous time-lapse recording in a New Zealand city

authors: Morgan, Dai K.J.

subjects: nest mortality

abstract: Predation of eggs and/or chicks is the main cause of nesting failure in birds. Nest predation has been studied in many habitats in New Zealand, but few studies have been conducted in urban ecosystems. Twenty-one nests of four bird species (blackbird [Turdus merula], song thrush [Turdus philomelos], fantail [Rhipidura fuliginosa], and silvereye [Zosterops lateralis]) were monitored over one breeding season in Hamilton using time-lapse recordings. Five predation events were filmed (two by cats [Felis catus], and three by ship rats [Rattus rattus]), 10 nests successfully fledged chicks and 6 nests failed owing to poor weather, desertion, or unknown events. Although the sample size was small, our data suggest that nesting success may be higher in urban Hamilton than in other unmanaged habitats where predation rates can exceed 80%. We recommend that future studies of nesting success in urban birds should also focus on the fates of fledglings, as anecdotal evidence suggested that predation rates may have been highest at this stage.

title: Māori tourism geographies: Values, morals and diverse economies

authors: Ringham, Sandra Lee

subjects: Māori tourism

abstract: Māori working in tourism negotiate moral terrains of their own world and those of visiting tourists, all of which are layered with colonial and capitalist values of Aotearoa New Zealand and beyond. We draw on research with Māori tourism providers in the North Island’s central, coastal and northern regions to address the question: How and in what ways do Māori working in tourism (re)construct their places and identities through practising Māori values in Aotearoa New Zealand’s tourism spaces? It is argued, using empirical material from interviews and par­ticipant sensing—a more-than-seeing form of participant observation—that diverse Māori values and practices shape tourism terrains and vice versa. The participants, who work with or for Māori tourism providers, practise and integrate Māori values into their lived geographies, and in doing so challenge dominant understandings of tourism, many of which are based on colonial and capitalist values. In this way, the participants reclaim and perform self-determination within Aotearoa New Zealand’s tourism spaces. This article focuses on two key themes. First, we look back at how past experiences of colonisation shape contemporary tourism. Second, we discuss the diverse and powerful ways Māori values reshape tourism geographies with a view to the potentialities of Māori tourism’s diverse economies.
