Power Production from Produced Waters via Reverse Electrodialysis: A Preliminary Assessment
2022
Wastewaters generated by crude oil extraction processes, called “produced waters” (PWs), are complex solutions that contain organic compounds, mainly hydrocarbons, and often exhibit high salinity. The large amounts of PWs represent a global issue because of their environmental impact. An approach widely used in the oil industry is the reinjection of this wastewater into the extraction wells after a suitable treatment. The high salt concentration of such solutions may be used in salinity gradient technologies to produce green electricity. Among these technologies, reverse electrodialysis (RED) is one of the most promising. In this work, the application of RED for energy generatio…
Building sustainable contextual ambidexterity through routines: a case study from information technology firms
2020
The purpose of this paper is to explain the role that routines play in achieving sustainable organisational ambidexterity in information technology (IT) firms. Our exploratory analysis of four case studies reveals the key importance of routines in setting the context for sustainable ambidexterity. Companies build up contextual ambidexterity through routines derived from normalization of processes, normalization of skills, and normalization of results. The findings of the study show that routines support IT professionals to decide whether to exploit or explore in each particular case. Firstly, the enabling character of explicit routines as a result of the normalisation of work processes and …
Visibilities and invisibilities in academic work and career building
2021
In the current turbulent higher education environment, academic work and career building are in a state of flux. The implementation of the principles of New Public Management have intensified managerial control over academic work. Growing dependence on external funding and metrics-based performance assessments have made career building increasingly competitive, selective, and risky. Disciplinary and organisational boundaries have been dissolving as interdisciplinary and cross-sectoral ways of collaboration have become policy priorities. These trends have challenged visible boundaries between disciplines, organisations, sectors, work tasks and academic roles. However, at the same time, new v…
Water-smart circular economy – Conceptualisation, transitional policy instruments and stakeholder perception
2022
Highlights • A concept for a water-smart Circular Economy (CE) is introduced. • Elements of a water-smart CE are presented. • Instruments to support the transition to a water-smart CE are analysed. • Drivers for and barriers to the transition to a water-smart CE are identified. The Circular Economy (CE) is a concept that has gained considerable global attention during the past decade amongst private and public sector actors, politicians and policymakers, citizens and media, and scientific communities. Water and water-related ecosystems, despite their vital role in practically all human activities, have been largely missing from conceptualisations and scientific definitions of the CE. Theref…
The use and abuse of parliamentary concepts in Hungarian parliamentary debates, 1920–27
2020
During and after the First World War, discourses calling for constitutional reform pervaded Europe. The break-up of the continental empires, the emergence of the new nation-states, and the western calls for democratization collectively gave rise to transnational debates about parliamentarization and parliamentary government. However, in the diverse and contingent post-war political environment, at the same time these ideals were given profoundly nation-specific meanings. They were implemented in the process of nation-building in equally diverse national contexts. This article analyses the use and abuse of the parliamentary concepts and their vernacular redescriptions in Hungarian parliament…
Implications of fisheries‐induced evolution for population recovery: Refocusing the science and refining its communication
2019
The argument that sufficiently high fishing mortality (selective or not) can effect genetic change in fished populations has gained considerable traction since the late 1970s. The intervening decades have provided compelling experimental and model‐based evidence that fisheries‐induced evolution (FIE) can cause genetic changes in life history, behaviour and body shape, given sufficiently high trait heritability, selection intensity and time. Fisheries‐induced evolution research has also identified or inferred negative implications to population recovery and sustainable yield, prompting calls for evolutionarily enlightened management to reduce the probability of FIE and mitigate its risks. Su…
A pragmatic high modernism? rural development and state building in the Ethiopian lowlands, c. 1960–2019.
2022
Large scale agricultural projects driven by a high modernist ideology have been closely interlinked with the process of state building at the Ethiopian lowland frontier since the second half of the twentieth century. This paper provides a diachronic analysis of the political economy of agricultural development and the associated frontier effect in the western and north-eastern lowlands of the country across three different political regimes. A comparative assessment of these patterns suggests that the high modernist paradigm should be applied with some qualification to the agenda of the Ethiopian People’s Revolutionary Democratic Front (EPRDF), the coalition that ruled Ethiopia from 1994 to…
3D survey in complex archaeological environments: An approach by terrestrial laser scanning
2018
Abstract. The survey of archaeological sites by appropriate geomatics technologies is an important research topic. In particular, the 3D survey by terrestrial laser scanning has become a common practice for 3D archaeological data collection. Even if terrestrial laser scanning survey is quite well established, due to the complexity of the most archaeological contexts, many issues can arise and make the survey more difficult. The aim of this work is to describe the methodology chosen for a terrestrial laser scanning survey in a complex archaeological environment according to the issues related to the particular structure of the site. The developed approach was used for the terrestrial laser s…
SCAN-TO-BIM FOR THE MANAGEMENT OF HERITAGE BUILDINGS: THE CASE STUDY OF THE CASTLE OF MAREDOLCE (PALERMO, ITALY)
2020
Abstract. Conservation and preservation of heritage buildings require the knowledge and sharing of a great deal of data and information about buildings. Such information comes from the different disciplines involved in the restoration and maintenance processes. The integration and use of all this information in a single working environment is a key factor for the success of historical building conservation and management projects. Heritage (or Historic) Building Information Modelling (HBIM) is nowadays the most appropriate tool to collect and manage all data related to Architectural Heritage. The HBIM process requires an in-depth knowledge of the historical building that can be achieved usi…
Experimental Investigation on the Performances of Innovative PV Vertical Structures
2019
The sustainable development of our planet is considerably related to a relevant reduction of CO2 global emissions, with building consumption contributing more than 40%. In this scenario, new technological conceptions, such as building-integrated photovoltaic technology, emerged in order to satisfy the requirements of sustainability imposed by the European Union. Therefore, the aim of this work is to provide a technical and economical comparison of the performances of different vertical-mounted innovative photovoltaic systems, potentially integrated on a building instead of on traditional windows or glass walls. The proposed investigation was carried out by means of experimental tests on thr…
