Green rosellas Platycercus caledonicus nesting in artificial structures

The Green Rosella Platycercus caledonicus nests primarily in hollows of living or dead eucalypt trees. This note describes an instance of Green Rosellas nesting in a wall cavity, and reviews other instances of nesting in artificial structures by this species. The building used in this instance appears to have been used by Green Rosellas in 2009 and 50 years earlier, in 1958.

Applying King et al.'s taxonomy to frame the IS discipline's engagement in green IS discourse

This paper considers how the IS discipline can engage with discourse on the institutions and their interventions which influence and regulate green IS innovation. To consider possible responses, we apply King et al.’s (1994) taxonomy, based on Institutional Theory, to frame a research agenda to guide future exploration and debate on the interventions to facilitate green IS innovation. Through the application of the taxonomy, we derive several pertinent questions for the discipline to consider as part of this debate. We conclude that the IS discipline can, and indeed should, play a more prominent role both through traditional responses (e.g., descriptive studies of green IS methodologies, organisational best practice, maturity models, etc.), but also through more active engagement in the form of participation and advocacy in shaping future green policy and regulation.

Implementing green business processes : the importance of functional affordances of information systems

An environmentally sustainable and thus green business process is one that delivers organizational value whilst also exerting a minimal impact on the natural environment. Recent works from the field of Information Systems (IS) have argued that information systems can contribute to the design and implementation of sustainable business processes. While prior research has investigated how information systems can be used in order to support sustainable business practices, there is still a void as to the actual changes that business processes have to undergo in order to become environmentally sustainable, and the specific role that information systems play in enabling this change. In this paper, we provide a conceptualization of environmentally sustainable business processes, and discuss the role of functional affordances of information systems in enabling both incremental and radical changes in order to make processes environmentally sustainable. Our conceptualization is based on (a) a fundamental definition of the concept of environmental sustainability, grounded in two basic components: the environmental source and sink functions of any project or activity, and (b) the concept of functional affordances, which describe the potential uses originating in the material properties of information systems in relation to their use context. In order to illustrate the application of our framework and provide a first evaluation, we analyse two examples from prior research where information systems impacted on the sustainability of business processes.

A comparison of the seasonal movements of tiger sharks and green turtles provides insight into their predator-prey relationship

During the reproductive season, sea turtles use a restricted area in the vicinity of their nesting beaches, making them vulnerable to predation. At Raine Island (Australia), the highest density green turtle Chelonia mydas rookery in the world, tiger sharks Galeocerdo cuvier have been observed to feed on green turtles, and it has been suggested that they may specialise on such air-breathing prey. However there is little information with which to examine this hypothesis. We compared the spatial and temporal components of movement behaviour of these two potentially interacting species in order to provide insight into the predator-prey relationship. Specifically, we tested the hypothesis that tiger shark movements are more concentrated at Raine Island during the green turtle nesting season than outside the turtle nesting season when turtles are not concentrated at Raine Island. Turtles showed area-restricted search behaviour around Raine Island for ~3–4 months during the nesting period (November–February). This was followed by direct movement (transit) to putative foraging grounds mostly in the Torres Straight where they switched to area-restricted search mode again, and remained resident for the remainder of the deployment (53–304 days). In contrast, tiger sharks displayed high spatial and temporal variation in movement behaviour which was not closely linked to the movement behaviour of green turtles or recognised turtle foraging grounds. On average, tiger sharks were concentrated around Raine Island throughout the year. While information on diet is required to determine whether tiger sharks are turtle specialists our results support the hypothesis that they target this predictable and plentiful prey during turtle nesting season, but they might not focus on this less predictable food source outside the nesting season.

Determinants of green supply chain implementation in the food and beverage sector

Using a grounded theory approach, this paper extracts emerging concepts in the implementation of green supply chain management from case data of New Zealand food and beverage (F&B) companies. In search of factors that may lead to theory-building, the study relates case studies in fruit, juice, and dairy product companies through in-depth interviews with ranking general and line managers. We uncover the outline of a theoretical framework focusing on determinants of GSCM behaviour. These include strategic and operational planning; management structure, systems, and decision-making; management of people and company culture; and relationships with supply-chain members.

Australia's green economic potential

This Centre for Policy Development briefing paper looks at the issues raised in the Green Economy Report from an Australian perspective and provides a primer to the challenges involved in transforming our economy to operate within environmental limits. It also examines the opportunities of embracing sustainable economic policy solutions in four areas: water, energy, cities and urban transport, and waste management and recycling.

Analysing stakeholder-associated risks in green buildings : a social network analysis method

In the research of risk associated with developing energy and water efficient green buildings, previous studies had mainly focused on "what the risks are and how the risks may impact on project objectives", which were from an inward looking self-perspective and treated the risks in isolation from one another. While intensive research efforts have been dedicated to risk identification, assessment, classification, prioritisation and mitigation, a research gap exists, that is previous studies had ignored the fact that most risks are interrelated and associated with internal or external project stakeholders. To remedy the gap, this current research developed and presented a SNA (Social Network Analysis) based stakeholder-associated risk analysis method to assess risks in green buildings and the interactions between the risks. A case study has been conducted to demonstrate and validate this method. This research contributes to the development of a new theory to model the interdependent and interactive relationships of risks by using SNA as a methodology. This research should broaden project managers' awareness of the influential risks in green building and enhance their ability to perceive, understand, assess, and mitigate the risks in an effective and efficient way, thereby achieving higher performance in strategic risk management and stakeholder communication in green building development.

A comparison of Australian rural and metropolitan cardiovascular risk and mortality: the Greater Green Triangle and North West Adelaide population surveys

Objectives:
Cardiovascular (CVD) mortality disparities between rural/regional and urban-dwelling residents of Australia are persistent. Unavailability of biomedical CVD risk factor data has, until now, limited efforts to understand the causes of the disparity. This study aimed to further investigate such disparities.
