title: Live television in a digital library

authors: Roüast, Maxime

subjects: digital libraries

abstract: The number of channels of digital television is increasing, particularly the number that are free-to-air. However due to the nature of broadcasting, this morass of information is not, for the main part, organized - -it is principally a succession of images and sound transmitted as multiplexed streams of data. Compare this deluge that terrestrially bombards our homes with the information available in the digital libraries we access over the Internet - -stored using software purpose built to help organize carefully curated sets of documents. This project brings together these two seemingly incompatible concepts to develop a software environment that concurrently captures all the available live television channels - -so a user does not need to proactively choose what to record - -and segments them into files which are then imported into a digital video library with a user interface designed to work from a multimedia remote control. A shifting time-based "window" of all recordings is maintained - -we settled on from the last two weeks so as to be practicably operable on a regular desktop PC. The system leverages off the information contained in the electronic program guide and the video recordings to generate metadata suitable for the digital library. A user evaluation of the developed prototype showed a high level of participant satisfaction across a range of attributes, notably date-based searching.

title: Listening to micro-business operators: what are their social and educational needs?

authors: Samujh, Helen

subjects: micro-business

abstract: This paper discusses issues that had been revealed during 15 in-depth interviews and a subsequent questionnaire survey of 91 micro-business (five or fewer employees) operators in Hamilton, New Zealand. ‘How to support micro-business operators in their efforts to achieve successful, sustainable self-employment within this changing social world?’ has been the guiding research theme. The questionnaire was used to gauge opinions on and the extent of attitudes and feelings about being self-employed that had been revealed during the in-depth interviews and small business literature. This work gives voice to the perspectives of micro-business operators rather than that of experts or small business operators in general.
Findings from this research suggest that micro-business operators need to be provided with opportunities for support and education to cope with psychological and social factors, particularly with fears, anxiety and isolation. Further, it appears that support is not available to micro-business operators in a way they can readily engage with. Lack of time appears as a reoccurring theme. Given the global trend towards self employment as a career option in the 21st Century, social policy makers need to be aware of the changing social and education needs and provide support to enhance micro-business start-up, survival and growth by encouraging initiatives that facilitate co-operative relationships and build social skills.

title: Materials for enhancing denitrification performance in partially saturated vertical flow wetlands for marae

authors: Liu, Lucian XiaoRan

abstract: There are upwards of 773 marae in New Zealand which are responsible for many key events for the indigenous people, Māori, many of which are located rurally and have inadequate on-site wastewater treatment mostly comprising of a septic tank followed by land application. Māori have many strong beliefs about water and subsequently criteria surround the treatment of wastewater due to the effects it can have on people and environment. One proposed solution that meets criteria are treatment wetlands, more specifically partially saturated vertical flow wetlands which require a smaller footprint and produce better effluent than traditional wetland designs. NIWA (National Institute of Water and Atmospheric Research) has experimented with mesocosm scale versions of this design and has encountered issues with denitrification in the saturated zone.

This research is therefore directed at enhancing denitrification in the saturated zone with materials that are able to supplement organic carbon for denitrification. Several woodchip materials (Eastern Cottonwood, Mahogany, Manuka, Eucalyptus, Crack Willow, Princess Tree and Pine) along with two industry by-product materials (Brewers Spent Grain and Slum gum) and Coir (Coconut derivative) were examined for denitrification capabilities and to serve in producing a leachate for dosing the proposed system to supplement organic carbon for denitrification.

The research is split into three phases; the first examines the ability of materials to release organic carbon into water over 60 days, the second examines the same but over three 10 day cycles, and the third quantifies denitrification performance of the materials at lab scale.

Results showed that producing a suitable leachate is not possible without the use of fresh material for each batch. By-product materials had great capacity for releasing organic carbon into water and denitrification (up to 85.5% nitrate removal) but had limited lifespans as media. While woodchip materials did not exhibit as great carbon release, they achieved comparable denitrification (74.2-74.5% nitrate removal) with long lifespans. Therefore, a woodchip and industry by-product mix could be the solution. Alternatively, there are many woodchip species, some which could have better denitrification capacity or suitable industry by-products with longer useful lifespans.
