title: The distribution of leadership as an influence on the implementation of a national policy initiative: the example of the Laptops for Teachers scheme

authors: Cowie, Bronwen

subjects: leadership

abstract: Research on the nature of and support for systemic sustainable innovation with ICT is converging with research on policy implementation and studies of school change and improvement to highlight the complex interplay of personal and contextual factors that enable and constrain innovation. In each of these fields, leadership has been found to play a crucial role in initiating and sustaining change and innovation. This leadership is not however the prerogative of any one individual but rather it is distributed over people at all levels of the system and across policies, practices and material resources. Leadership for innovation around and with ICT technologies is also distributed across time because of its substantial financial and knowledge implications. In this article, we illustrate the distributed nature of the leadership that supported teachers and schools to make use of teacher personal laptops accessed through the New Zealand government Laptops for Teachers scheme.

title: Influence of Potamogeton crispus growth on nutrients in the sediment and water of Lake Tangxunhu

authors: Mi, W. J.

subjects: submerged macrophyte

abstract: An incubation experiment was performed on Potamogeton crispus (P. crispus) using sediment collected from Lake Tangxunhu in the center of China, in order to determine the effects of plant growth on Fe, Si, Cu, Zn, Mn, Mg, P, and Ca concentrations in the sediments and overlying waters. After 3 months of incubation, Ca, Mg, and Si concentrations in the water column were significantly lower, and P and Cu concentrations were significantly higher than in unplanted controls. The effect of P. crispus growth on sediment pore waters and water-extractable elements varied. Concentrations of Ca, Mg, Si, Fe, Cu, and Zn were significantly higher, and P was significantly lower, than in pore waters of the control. Water-extracted concentrations of Fe, Mg, and Si in the sediments were lower, and P was higher, than in the control. Presence of P. crispus generally enhanced concentration gradients of elements between pore waters and overlying waters but not for P. The growth of P. crispus was associated with an increase in water pH and formation of root plaques, resulting in complex effects on the sediment nutritional status.

title: What land is included?

authors: Oppatt, Neil

abstract: Neil has served the Rotorua District as both a Rotorua District Councillor for 15 years and now 9 years as a BOP Regional Councillor. Throughout this time Neil has been actively involved in the cleanup of Rotorua's lakes. He is presently a BOPRC appointee on the Rotorua Te Arawa Lakes Strategy Group and was an RDC appointee on its predecessor.
He has held positions as Chairman of RDC’s Finance Committee, BOPRC’s Operations and Regulations Committee and the Special Projects Committee set up to address Rotorua lake issues. Neil chaired the Lake Okareka Action Plan Committee and was a BOPRC appointee on the Lake Tarawera Action Plan Committee. Presently he is the BOPRC appointee on the Rotorua catchment Stakeholders Advisory Group.
