title: Neo-structuralist analysis of green-marketing discourse: interpreting hybrid car manufacturers and consumers

authors: Kadirov, Djavlonbek

subjects: culture

abstract: To explain inconsistent behaviour that is well documented in green-marketing and consumption, the authors develop the (neo)structuralist model of meaning co-creation that is based on the signifying practices of hybrid car manufacturers and consumers. The model reveals that market agents are recruited into a symbolic order that requires the perpetual reinforcement of self-opposing meanings as a condition for signification. The main problem of green practice is not the issue of market agents' authenticity/hypocrisy. Rather it represents a more interactive phenomenon – the common structure of meaning-creation – which silences important transformative action choices and thus defeats its own purpose.

title: A combined optical, thermal and electrical performance model of a Building Integrated Photovoltaic/Thermal Concentrator (BIPVTC)

authors: Anderson, Timothy Nicholas

subjects: component

abstract: The electrical output of concentrating photovoltaic devices is significantly affected by the temperature of the photovoltaic cells. The ability to actively cool photovoltaic cells under concentrated radiation allows their electrical efficiency to be maintained particularly during periods of high solar radiation when concentration offers the maximum benefit. In this study, the design of a novel photovoltaic/thermal solar concentrator for building integration (BIPVTC) is discussed. The optical, thermal and electrical performance of the collector was theoretically modelled and validated with experimental data. The results show that BIPVTC offers improved electrical yields from both concentrating radiation onto the photovoltaic cells and also by actively cooling them.

title: Current state of the Rotorua Lakes

authors: Hamilton, David P.

abstract: The Rotorua Te Arawa Lakes’ programme of restoration has arguably been the most ambitious and effective of any for a group of lakes around the world. It has been characterised by willingness to ‘try things’, to be guided closely by scientific input, and to
now have excellent structures for monitoring and implementation of actions. Still, major challenges remain. One of these is the potential for a sense of complacency, particularly when some lakes have responded extremely positively to in-lake treatments (e.g. Rotorua) or major one-off actions (e.g. Rotoiti). It is essential that these improvements in lake water quality, some of which may not be able to be maintained indefinitely in their current mode, not delay further catchment management actions.
Another challenge is exotic oxygen weeds, particularly where it is difficult to harvest large accumulations. The final challenge relates to climate. Recent years have been characterised by droughts and intense rainfall events that challenge land management practices. Further, surface water temperatures in the lakes in 2015 have been greater than at any time in the past. If these changes are symptomatic of a future climate, then there will need to be greater effort put into building resilience in the lakes and their catchments.
