Recent studies suggest that coastal ecosystems can bury significantly more C than tropical forests, indicating that continued coastal development and exposure to sea level rise and storms will have global biogeochemical consequences. The Florida Coastal Everglades Long Term Ecological Research (FCE LTER) site provides an excellent subtropical system for examining carbon (C) balance because of its exposure to historical changes in freshwater distribution and sea level rise and its history of significant long-term carbon-cycling studies. FCE LTER scientists used net ecosystem C balance and net ecosystem exchange data to estimate C budgets for riverine mangrove, freshwater marsh, and seagrass meadows, providing insights into the magnitude of C accumulation and lateral aquatic C transport. Rates of net C production in the riverine mangrove forest exceeded those reported for many tropical systems, including terrestrial forests, but there are considerable uncertainties around those estimates due to the high potential for gain and loss of C through aquatic fluxes. C production was approximately balanced between gain and loss in Everglades marshes; however, the contribution of periphyton increases uncertainty in these estimates. Moreover, while the approaches used for these initial estimates were informative, a resolved approach for addressing areas of uncertainty is critically needed for coastal wetland ecosystems. Once resolved, these C balance estimates, in conjunction with an understanding of drivers and key ecosystem feedbacks, can inform cross-system studies of ecosystem response to long-term changes in climate, hydrologic management, and other land use along coastlines.

Historical archaeology, in its narrow temporal sense -as an archaeology of the emergence and subsequent evolution of the Modern world- is steadily taking pace in Spanish academia. This paper aims at provoking a more robust debate through understanding how Spanish historical archaeology is placed in the international scene and some of its more relevant particularities. In so doing, the paper also stresses the strong links that have united historical and prehistorical archaeology since its inception, both in relation to the ontological, epistemological and methodological definition of the first as to the influence of socio-political issues in the latter. Such reflection is partly a situated reflection from prehistory as one of the paper’s authors has been a prehistorian for most of her professional life.

In 2012, Uganda celebrated 50 years of independence. The postcolonial era in the country has been marked by political turmoil and civil wars. Uganda, like many other postcolonial states in Africa, cannot be described as an ethnically or culturally homogenous state. However, history education has globally been seen as a platform for constructing national identities in contemporary societies. At the same time, it is assumed that specific historical experiences of countries influence historical understanding. This study takes its starting point in the theories of historical consciousness and narrativity. A narrative could be viewed as a site where mobilization of ideas of the past to envisage the present and possible futures is made and hence the narrative expresses historical orientation. Through the concept of historical orientation historical consciousness can be explored, i.e. what history is viewed as significant and meaningful. The aim in the study is to explore in what ways students connect to their historical pasts.   The study explores 219 narratives of 73 Ugandan upper secondary students. Narratives elicited through written responses to three assignments. Designed to capture different approaches to history: either to start from the beginning and narrate history prospectively or to depart from the present narrating retrospectively. The colonial experience of Uganda affected the sampling in the way that students were chosen from two different regions, Central and Northern Uganda. The comparison was a way to handle the concept of ‘nation’ as a presupposed category. Narrative analysis has been used as a method to explore what the students regarded as historically significant and what patterns among the narratives that point towards particular historical orientations.   The empirical results show how different approaches to history, a prospective or a retrospective approach, influence the student narratives. For instance, valued judgments on past developments were more common with the retrospective approach. The results also show differences in evaluating past developments according to regional origin. Students from northern Uganda were generally more inclined to tell a story of decline. Also, it is argued that the student narratives were informed by a meta-narrative of Africa. It was as common to identify oneself as African as it was to identify as Ugandan.

Troubled dynamics between residents of an Aboriginal town in Queensland and the local health system were established during colonisation and consolidated during those periods of Australian history where the policies of 'protection' (segregation), integration and then assimilation held sway. The status of Aboriginal health is, in part, related to interactions between the residents' current and historical experiences of the health and criminal justice systems as together these agencies used medical and moral policing to legitimate dispossession, marginalisation, institutionalisation and control of the residents. The punitive regulations and ethnocentric strategies used by these institutions are within the living memory of many of the residents or in the published accounts of preceding generations. This paper explores current residents' memories and experiences.

Off-site Manufacture (OSM) has long been recognised, both in Australia and internationally, as offering numerous benefits to all parties in the construction process. More importantly, it is recognised as a key vehicle for driving improvement within the construction industry. The uptake of OSM in construction is however limited, despite well documented benefits. The research aims to determine the ‘state-of-the-art’ of OSM in Australia. It confirms the benefits and identifies the real and perceived barriers to the widespread adoption of OSM. Further the project identifies opportunities for future investment and research. Although numerous reports have been produced in the UK on the state of OSM adoption within that region, no prominent studies exist for the Australian context. This scoping study is an essential component upon which to build any initiatives that can take advantage of the benefits of OSM in construction. The Construction 2020 report predicted that OSM is set to increase in use over the next 5-15 years, further justifying the need for such a study. The long-term goal of this study is to contribute to the improvement of the Australian construction industry through a realisation of the potential benefits of OSM.

Off-site manufacture (OSM) offers numerous benefits to all parties in the construction process. The uptake of OSM in Australia has, however, been limited. This limited uptake corresponds to similar trends in the UK and US, although the level of OSM there appears to be increasing. This project undertook three workshops — one each in Victoria, Queensland and Western Australia — and 18 interviews with key stakeholders to assist in identifying the general benefits and barriers to OSM uptake in the Australian construction industry. Seven case studies were also undertaken, involving construction projects that used OSM, ranging from civil projects through to residential. Each of these case studies has been analysed to identify what worked and what didn’t, and suggest the lessons to be learned from each project.
