title: Access and Use of Teaching and Research Materials from A Copyright Perspective in Fiji and the Philippines

authors: Dimitrov, Dara

abstract: This study fills the gap created by the lack of research on educators’ perspectives on copyright protected resources in Fiji and the Philippines and identifies the challenges and strategies they undertake when confronted with material protected by copyright law.

title: Speed control of small motors through the Ćuk Converter Topology

authors: Hutchins, Michael

subjects: motor speed control

abstract: The Ćuk Converter offers simultaneous buck-boost operation, but requires careful design owing to its having a fourth-order transfer function and numerous practical design constraints. We exploit a serendipitous overlap between the converter circuit and the equivalent circuit of a dc motor to design a motor controller that can operate with supply voltage that is lower than the motor full-speed requirement. We examine the transfer function when such a topology is used to control the speed of a small motor. We conclude that the approach is relatively straightforward owing to the impact of the motor’s inductance. Measurements agree with theory.

title: La gouvernance des rivières en Nouvelle-Zélande : une solution élégante ?

authors: Te Aho, Linda

subjects: Water governance,

abstract: Governance of Water in New Zealand: An Elegant Solution? This chapter is grounded in the context of Aotearoa New Zealand while drawing on larger references, such as the United Nations Declaration on the Rights of Indigenous peoples, the Rio+20 Declaration and constitutional provisions for Rights of Nature. The chapter analyses a proposed new model for the contentious issue of freshwater governance in New Zealand based on responsible use which also addresses the complex world of state-Māori relations.
