title: Betterment taxes, capital gains and benefit cost ratios

authors: Coleman, Andrew

subjects: betterment tax

abstract: ‘Betterment’ taxes can be used to fund infrastructure investments. We relate betterment taxes to the benefit: cost ratio, deriving conditions under which a project can be funded by such taxes, and relate betterment taxes also to a capital gains tax.

title: Total site methodology as a tool for planning and strategic decisions

authors: Nemet, Andreja

subjects: Electricity production

abstract: A Total Site (TS) is defined as a set of processes (industrial plants, residential, business and agriculture units) linked through the central utility system. The utility system incorporates a number of operating units such as boilers, steam turbines, gas turbines and letdown stations. Many sites are using the TS system representation. Heat Integration at TS level has been well developed and successfully implemented. However, sites typically develop with time and even minor changes/extensions can affect TS heat recovery significantly. It is beneficial to plan their strategic development in advance, to increase or at least not to decrease the rate of heat recovery when integration of additional processes takes place. Even when this has not been done at the initial stage, the TS methodology can still be used as a tool for the strategic planning decision making. This work illustrates how the TS methodology can contribute to the strategic development and the extension planning of already existing TS. The aim is to reveal the potentials for Heat Integration, when new units or processes are considered for the inclusion in the TS. Moreover, some operating parameters (e.g. temperature or capacity) of the unit can be proposed to achieve the best possible heat recovery. The degrees of freedom for TS changes can be on two levels: (i) only adding an operating unit to the current utility system (the Total Site Profiles remain the same) or (ii) changing of the TS by including more processes (the Total Site Profiles are changed). The first group of changes includes the integration of heat engines to produce electricity utilising heat at higher temperature and returning it to the system at lower temperature, which is still acceptable for the heat recovery and simultaneously for the electricity production. The second group of changes is more complex. For evaluating these changes a plus/minus principle is developed allowing the most beneficial integration of new units to the TS. Combinations of both types of changes are also considered.

title: Are historical perpetual leases on Maori owned land (Native reserves) a basis for currently enforceable fiduciary obligations?

authors: Dimitrov, Dara

subjects: fiduciary obligations

abstract: Colonial perpetual leases over what were once native reserves continue to trouble the New Zealand government. The colonial Public Trust Office was tasked with managing and administering Māori property affairs, with a focus on the administration of the native reserves. However, if the perpetual leases continue to be viewed through the contractual lens, relief for the Māori landowners will not be forthcoming. Therefore, examining the rationale for imposing fiduciary duties upon the colonial Public Trust Office is essential. Where traditional legal fiduciary literature explores the onerous proscriptive duties that bind persons occupying a fiduciary position, this article establishes that the extensive statutory role assigned to colonial Public Trust officers in managing the native reserves for their Māori beneficiaries created a fiduciary relationship. Moreover, this article shows that, when the colonial Public Trust Office exercised its powers, this often led to conflicts of interest with their Māori beneficiaries.
