Can sand slugs in rivers deliver conservation benefits? The biodiversity value of tributary junction plug wetlands in the Glenelg River, Australia

Restoration works are carried out to alleviate human impacts and improve habitats within ecosystems. However, human impacts may also create new (anthropogenic) habitat for species to exploit.A dilemma arises when proposed restoration works would remove anthropogenic habitat and the assemblages it supports. Sediment input into the Glenelg River has formed tributary junction plug wetlands at confluences. Sand slug removal is proposed as part of river rehabilitation, but would also drain plug wetlands. We sampled four plug wetland, four river run and three river pool sites to determine whether plug wetlands influence water quality and add to the biodiversity of macroinvertebrates in the Glenelg River.Water quality and macroinvertebrate diversity were similar in plug wetlands, river runs and river pools.Assemblages were distinct among all sites, regardless of type, so there was no characteristic ‘plug-wetland fauna’. Therefore, although removal of plug wetlands would not cause a dramatic loss of invertebrate biodiversity, it would destroy anthropogenic habitat that supports a similar range of species to natural habitats in a river subject to multiple degrading processes. Gains from rehabilitation should be weighed against the value of anthropogenic habitat and the extent of similar habitat lost elsewhere in the ecosystem.

Cultivating health and wellbeing : members' perceptions of the health benefits of a Port Melbourne community garden

This paper reports on a research project undertaken with members of a community garden in Port Melbourne, Australia, to investigate the ways in which such a facility contributes to the enhancement of health, wellbeing and contact with nature for urban dwellers. Ten members from an urban community garden were interviewed using qualitative semi-structured questions exploring perceptions of health and wellbeing benefits associated with membership. The garden was felt by members to be a sanctuary where people could come together and escape daily pressures, a source of advice and social support, and a place which gave them a sense of worth and involvement. Members also identified spiritual, fitness and nutritional benefits arising from participation in the community garden. It is evident even from this small qualitative study that community gardening offers many health and wellbeing benefits to members. This study provides a basis for the benefits of community gardens in Australia to be taken into account by policy-makers and practitioners to enhance urban community health and wellbeing.

Implementation, communication and benefits of corporate codes of ethics : an international and longitudinal approach for Australia, Canada and Sweden

This paper examines the implementation, communication and benefits of corporate codes of ethics by the top companies operating in Australia, Canada and Sweden. It provides an international comparison across three continents. It is also based on a longitudinal approach where three national surveys were performed in 2001–2002 and replications of the same surveys were performed in 2005–2006. The empirical findings of this research show in all three countries that large organisations indicate a substantial interest in corporate codes of ethics. There are, however, differences in the ways that the companies in each country implement and communicate their corporate codes of ethics and the benefits that they see being derived from them. The longitudinal comparison between 2001–2002 and 2005–2006 indicates changes in the implementation, communication and benefits of corporate codes of ethics in the three countries.

Maximising the benefits of radio frequency identification technology (RFID) integration in clinical contexts : a linear conduit

Radio Frequency Identification Technology (RFIO) has been explored for various process enhancements in clinical contexts, particularly hospitals, for asset tracking. The technology has been accepted in such environments, as it is inexpensive and, in principle, uncomplicated to integrate with other clinical support systems. It is perceived to offer many benefits to currently resource critical/strained clinical environments. This research investigation focuses on the exploitation of the potential of the technology, to enhance processes in clinical environments. In this paper, the researchers aimed to uncover if the technology, as presently deployed, has been able to achieve its potential and, in particular, if it has been fully integrated into processes in a way that maximises the benefits that were perceived. This research is part of a larger investigation that aims to develop a meta-model for integration of RFIO into processes in a form that will maximise benefits that may be achievable in clinical environments. As the first phase of the investigation, the key learning from a clinical context (hospital), which has deployed RFIO and attempted to integrate it into the processes, to enable better efficiencies, is presented in this paper. The case method has been used as a methodological framework. Two clinical contexts (hospitals) are involved in the larger project, which constitutes two phases. In Phase 1, semi structured interviews were conducted with a selected number of participants involved with the RFIO deployment project, before and after, in clinical context 1 (hereinafter named as CCl). The results were then synthesised drawing a set of key learning, from different viewpoints (implementers and users), as reported in this paper. These results outline a linear conduit for a new proposed implementation (CC2). On completion of the phase II, the researchers aim to construct a meta-model for maximising the potential of RFIO in clinical contexts. This paper is limited to the first phase that aims to draw key learning to inform the linear conduit.

Carbon rights as new property: the benefits of statutory verification

This paper examines the different ways in which carbon rights have been verified as property interests. A carbon right is a new and unique form of land interest that confers upon the holder a right to the incorporeal benefit of carbon sequestration on a piece of forested land. Carbon sequestration refers to the absorption from the atmosphere of carbon dioxide by vegetation and soils and the storage of carbon in vegetation and soils. Innovative legislation has been introduced in each state seeking to separate the incorporeal benefit of carbon sequestration from the natural rights flowing from land ownership. The fragmentation of land ownership in this way is a constituent of broader climate change strategies and is particularly important for an Australian emissions trading scheme where carbon rights will acquire value as tradable offsets. This paper will explore the different legislative responses of each state to the proprietary characterisation of the carbon right as a land interest. It will argue that verifying the carbon right as a new statutory property interest, in line with the approach set out in the Carbon Rights Act 2003 (WA), is preferable to aligning it with preconceived categories of common law servitude. By articulating the  carbon right as a new form of statutory interest, unique in status and form, its sui generis character is more accurately reflected. Further, statutory validation of the carbon right as a new land interest is more efficient as legislative rules are more visible and therefore come to the attention of other market participants more quickly and at a lower cost without the burden and complexity associated with expressing the right through the prism of pre-conceived and non-responsive common law forms.

Who benefits most from participating in chronic disease self-management programs?

Objectives: To quantify the benefits that people receive from participating in self-management courses and identify subgroups that benefit most.
Research Design: People with a wide range of chronic conditions attending self-management courses (N=1,341 individuals) were administered the generic Health Education Impact Questionnaire (HEI-Q). Data were collected before the first session (baseline) and at the end of courses (follow-up) resulting in 842 complete responses. The median (interquartile range) age was 64 (54 to 73) years and most participants were female (75%). Outcomes were categorized as Substantial improvement (Effect Size, ES ≥ 0.5), Minimal/No change (ES -0.49 to 0.49) and Substantial decline (ES ≤ -0.5).
Results: On average, one third of participants reported substantial benefits after attending a self-management course. Proportions of participants reporting substantial benefits ranged from 49% in Skill and technique acquisition to 27% in Health service navigation. Stratification by gender, age and education showed that younger participants were more likely to benefit, particularly young women. No further subgroup differences were observed.
Conclusions: Given that the health of people with chronic diseases tends to decline, this evaluation is reassuring in that about one third of participants coming from a wide range of backgrounds receive substantial improvements in their self-management skills.
