There is widespread recognition that higher education institutions have an important role to play in the transition towards a more sustainable global society. In this context, many universities have embarked on a journey towards 'sustainability', and there has been increasing research on related processes of organizational change. There is evidence that 'human' factors have an important role to play in change processes and numerous case studies capture how these occur, but there is little synthesis of qualitative research in this area. This paper presents a meta-ethnography of 13 qualitative studies from peer reviewed academic publications. Using a grounded approach, we identified nine themes which we then synthesized in order to develop an in-depth understanding of organizational change processes for sustainability. This led to the identification of a number of hidden contradictions and tensions that seem to characterize such processes. These contradictions and tensions lead to recurring barriers to change and issues that can undermine the very sustainability of change processes. These issues are also influenced by the perception of who has power to affect change, networks and institutional structures. We discuss the implications for research and practice and suggest the need to recognize existing tensions and contradictions through reflexive practice and genuine dialogue as well as developing flexible structures and moving towards 'double loop' learning within institutions. The meta-ethnography presents a look beyond the surface of what has become an increasingly important area of institutional change in higher education, helps to inform practice, and contributes to emerging research imperatives.

This paper argues that the need for a core -fourth pillar‖ of sustainability/sustainable development, as demanded in multiple arenas, can no longer be ignored on the grounds of intangibility. Different approaches to this vital but missing pillar (cultural-aesthetic, religious-spiritual, and political-institutional) find common ground in the area of ethical values. While values and aspects based on them are widely assumed to be intangible and immeasurable, we illustrate that it is possible to operationalize them in terms of measurable indicators when they are intersubjectively conceptualized within clearly defined practical contexts. The processes require contextual localization of items, which can nonetheless fit into a generalizable framework. This allows useful measurements to be made, and removes OPEN ACCESSSustainability 2013, 5 3036 barriers to studying, tracking, comparing, evaluating and correlating values-related dimensions of sustainability. It is advocated that those involved in operationalizing sustainability (especially in the context of creating post-2015 Sustainable Development Goals), should explore the potential for developing indicators to capture some of its less tangible aspects, especially those concerned with ethical values.

Heavy metals in urban soils continue to attract attention because of their potential long-term effects on human health. During a previous investigation of urban soils in Galway City, Ireland, a pollution hotspot of Pb, Cu, Zn and As was identified in the sports ground of South Park in the Claddagh. The sports ground was formerly a rubbish dumping site for both municipal and industrial wastes. In the present study, a portable X-ray fluorescence (PXRF) analyser was used to obtain rapid in-situ elemental analyses of the topsoil (depth: about 5-10 cm) at 200 locations on a 20 x 20-m grid in South Park. Extremely high values of the pollutants were found, with maximum values of Pb, Zn, Cu and As of 10,297, 24,716, 2224 and 744 mg/kg soil, respectively. High values occur particularly where the topsoil cover is thin, whereas lower values were found in areas where imported topsoil covers the polluted substrate. Geographic Information Systems (GIS) techniques were applied to the dataset to create elemental spatial distribution maps, three-dimensional images and interpretive hazard maps of the pollutants in the study area. Immediate action to remediate the contaminated topsoil is recommended to safeguard the health of children who play at the sports ground.

A large, successful, residential food waste sorting (recycling) program in urban high-density housing was studied to elicit perceptions of the key elements of its success. An embedded mixed-methods approach was used with rigorous quantitative measures of weights and compositions of the waste to confirm the success of the program, combined with in-depth semi-structured interviews of stakeholders to reveal their opinions of the elements key for success. The program produced a 70% food waste capture rate slowly decreasing to 45% over 54 weeks, with <1% contamination. The key elements for success were found to relate to clarification of roles and responsibilities, and the usefulness of a ‘broker’ (here, an NGO) to co-develop new boundaries for stakeholder responsibilities. Residents who acknowledged their responsibility to sort their waste viewed it as civic duty, but first needed to be convinced of the serious intention of the local government to implement the policy. Residents with strong relationships with the local government – e.g. due to greater ongoing interactions – were perceived to perform better. The use of volunteers to demonstrate and interact on a personal level with residents was seen as a key element. The three month period of volunteer involvement was seen as key to good habit formin
