title: Evaluating environmental policies under uncertainty through application of robust nonlinear programming

authors: Doole, Graeme J.

subjects: nonpoint pollution

abstract: Environmental policy evaluation is characterised by a paucity of information. The novel technique of robust mathematical programming is introduced as a means to proactively account for this uncertainty in policy analysis. The procedure allows identification of expected bounds on the range of abatement costs associated with environmental policy. It also has the advantage of not limiting conclusions to realisations of specific point estimates or probability distributions. Empirical insights are provided in an application to a New Zealand inland lake threatened by nitrate pollution from dairy farming. Overall, this novel framework is demonstrated to have several key advantages, including explicit treatment of severe uncertainty, capacity to bound the range of expected abatement costs accruing to a given policy instrument, and the opportunity to identify robust plans that are immune to parametric variation.

title: Work overload, parental demand, perceived organizational support, family support, and work-family conflict among New Zealand and Malaysian academics

authors: Nasurdin, Aizzat Mohd

abstract: Relationships between work overload and parental demands with work-family conflict were investigated among New Zealand and Malaysian academics. In addition, social support from the work and family domains were explored as moderators in the proposed relationships. Two public universities, one located in New Zealand and the other in Malaysia, participated in the study. Analysis of data gathered from 202 academic staff from New Zealand and 183 from Malaysia demonstrated similar findings concerning the positive relationships between work overload and work-to-family interference across the two samples. Contrary to prediction, parental demand was found to be unrelated to family-to-work interference in both samples. In addition, no evidence emerged for the moderating effects of perceived organizational support and the two forms of family support. Implications of the findings and suggestions for future research are discussed.

title: Alum dosing of Waitangi Stream: Biomonitoring of aluminium 2021-2023

authors: Tempero, Grant Wayne

abstract: Continuous alum dosing of the Waitangi Stream at Lake Rotoehu commenced in 2011 to reduce concentrations of dissolved reactive phosphorus in this inflow to the lake and improve water quality. The Bay of Plenty Regional Council contracted the University of Waikato to undertake monitoring of biota in the Waitangi Stream for potential impacts due to alum dosing. Macroinvertebrate community analysis and tissue aluminium concentrations in kōura (Paranephrops planifrons) and goldfish (Carassius auratus) have been undertaken annually since 2013 to determine the impacts and bioaccumulation of aluminium.
