title: Exploring the IT usage in SMEs from New Zealand, Columbia and Chile using action-research methodology

authors: Cataldo, Alejandro

subjects: action-research

abstract: The theory on the adoption and use of information technology (IT) in small and medium enterprises (SMEs) is abundant. However, methodologically speaking, action-research (AR) has been little explored as a method of construction of this theory, despite the use of this methodology could improve understanding of how SMEs use IT. Therefore, we researched the use of IT in SMEs using a methodology adapted from AR. The methodology was tested in companies from New Zealand, Colombia and Chile. The use of this methodology was well evaluated by the top management of SMEs, in fact, the recommendations coming from the analysis were well received by the management of participants. These results are auspicious regarding the use of AR in SMEs and could help encourage other researchers to use this  methodology, which remains little used in information systems research.

title: Re-interpreting old dates: Radiocarbon determinations from the Tokelau Islands (South Pacific)

authors: Petchey, Fiona

subjects: radiocarbon

abstract: A re-evaluation of available archaeological radiocarbon dates from the Tokelau Islands in West Polynesia demonstrates that careful assessment is essential when developing chronologies from previously published radiocarbon data. The new calibration results point to concurrent and continual human occupation of Fakaofo and Atafu from at least 750-550 years ago up until European contact in AD 1765.

title: Recognising the negative impacts of aquatic weed management: Okawa Bay, Lake Rotoiti case study

authors: Scholes, Paul

abstract: The Te Arawa Rotorua Lakes Programme continues to implement measures to maintain and restore lake water quality in line with trophic level indices (TLI’s) for respective lakes. In Lakes Rotorua and Rotoiti this has also meant not only reducing nutrients to and in the lakes but also managing periodic cyano-bacterial (blue-green) algal blooms.
Restoration measures in the Rotorua and Rotoiti catchments have included land use management efforts to arrest nutrient inputs; diversion of Lake Rotorua waters from entering Rotoiti; sewage reticulation of lakeside communities; and treatment of inflows
with aluminium sulphate (alum). While restoration efforts have produced water quality gains in both lakes, in recent years, cyano-bacterial blooms have occurred in the shallow embayment of Lake Rotoiti, known as Okawa Bay.
These water quality gains have not come without a cost. Submerged aquatic weeds such as Hornwort are an increasing problem in the Rotorua Te Arawa Lakes and significant resources are needed to manage infestations primarily for aesthetic and recreational
amenity. Control of exotic aquatic weed is mostly with application of herbicide. Herbicide treatment leaves a decomposing biomass in the waterbody, potentially increasing the nutrient status.
We examine the impact aquatic weed decomposition has had on Okawa Bay’s nutrient status and the cyano-bacterial blooms over recent summers, and Bay of Plenty Regional Council’s response to reduce localised bloom development.
