Engineering sustainability through language

As our understanding and care for sustainability concerns increases, so does the demand for incorporating these concerns into software. Yet, existing programming language constructs are not well-aligned with concepts of the sustainability domain. This undermines what we term technical sustainability of the software due to (i) increased complexity in programming of such concerns and (ii) continuous code changes to keep up with changes in (environmental, social, legal and other) sustainability-related requirements. In this paper we present a proof-of-concept approach on how technical sustainability support for new and existing concerns can be provided through flexible language-level programming. We propose to incorporate sustainability-related behaviour into programs through micro-languages enabling such behaviour to be updated and/or redefined as and when required

On the role of value sensitive concerns in software engineering practice

The role of software systems on societal sustainability has generally not been the subject of substantive research activity. In this paper we examine the role of software engineering practice as an agent of change/impact for societal sustainability through the manifestation of value sensitive concerns. These concerns remain relatively neglected by software design processes except at early stages of user interface design. Here, we propose a conceptual framework and language concepts that will translate value sensitive design from its current focus in participatory design to one located in mainstream software engineering processes. Addressing this need will have an impact of societal sustainability and we outline some of the key research challenges for that journey

European project semester: 30 ECTS of PBL in sustainability with multicultural and multidisciplinary bachelor students groups

Since 1991, the Technical University of Catalonia has focussed on introducing Sustainability education in all its engineering and architectural programmes through two environmental plans (1996-2000, 2000-2005), and currently through the UPC Sustainable 2015 [1] plan. Under this framework, the School of Engineering of Vilanova i la Geltrú (EPSEVG) has designed and coordinated the European Project Semester (EPS), an innovative learning programme which responds to the challenges of society and the European Higher Education Area. EPS trains engineering students by applying Project Based Learning in intercultural and multidisciplinary groups. The working language is English and the programme is designed for 1st cycle (Bachelor) degrees. The EPS programme offered at the EPSEVG emphasises the introduction of competences in sustainability [2] and human technology. The main objective of the EPS is to improve the learning outcomes and competences of engineering students in relation to communication and teamwork skills, the ability to work in intercultural settings, and the ability to work in real multidisciplinary projects with students from different degree backgrounds. The EPS is divided into seminars (worth 10 ECTS) and a project (worth 20 ECTS). The seminars include courses in Sustainable Technologies, Business and Sustainability and Human Technology, among others. The projects are proposed by local companies and research groups. Since 2008 the number of participants has increased from 9 in 2008 to 30 in 2011. The students, who have participated in 15 projects, have come from 16 different European and North American universities and from over 18 different academic disciplines. This paper shows the design methodology used in the EPS programme its structure and the sustainability competences achieved by the students.Postprint (published version

Sustainability of the chemical manufacturing industry - Towards a new paradigm?

This paper describes the current situation of the chemicalmanufacturingindustry, with special reference to Europe and looks to the future sustainability demands on the sector, and the implications of these demands for chemical engineering education. These implications include definitions of sustainability criteria for the sector and the need for transparent reporting under the Triple Bottom Line approach. The response of the education system to the sustainability agenda over the years and a number of strategies to incorporate it into courses are described. The important role of chemical (or more generally, process) engineers in delivering sustainable solutions is emphasised but this also suggests that anew way of thinking about the discipline is required. Indeed, this paper argues that the demand for a sustainable chemicalmanufacturing sector could bring about the next paradigm shift in the discipline which has been predicted for some time

Empirical research on the evaluation model and method of sustainability of the open source ecosystem

The development of open source brings new thinking and production modes to software engineering and computer science, and establishes a software development method and ecological environment in which groups participate. Regardless of investors, developers, participants, and managers, they are most concerned about whether the Open Source Ecosystem can be sustainable to ensure that the ecosystem they choose will serve users for a long time. Moreover, the most important quality of the software ecosystem is sustainability, and it is also a research area in Symmetry. Therefore, it is significant to assess the sustainability of the Open Source Ecosystem. However, the current measurement of the sustainability of the Open Source Ecosystem lacks universal measurement indicators, as well as a method and a model. Therefore, this paper constructs an Evaluation Indicators System, which consists of three levels: The target level, the guideline level and the evaluation level, and takes openness, stability, activity, and extensibility as measurement indicators. On this basis, a weight calculation method, based on information contribution values and a Sustainability Assessment Model, is proposed. The models and methods are used to analyze the factors affecting the sustainability of Stack Overflow (SO) ecosystem. Through the analysis, we find that every indicator in the SO ecosystem is partaking in different development trends. The development trend of a single indicator does not represent the sustainable development trend of the whole ecosystem. It is necessary to consider all of the indicators to judge that ecosystem’s sustainability. The research on the sustainability of the Open Source Ecosystem is helpful for judging software health, measuring development efficiency and adjusting organizational structure. It also provides a reference for researchers who study the sustainability of software engineering

On the sustainability of web systems evolution

In the last twenty years, the evolution of web systems has been driven along three dimensions: the processes used to develop, evolve, maintain and re-engineer the systems themselves; the end products (the pages, content and links) of such processes; and finally the people dimension, with the extraordinary shift in how developers and users shape, interact and maintain the code and content that they put online. This paper reviews the questions that each of these dimensions has addressed in the past, and indicates which ones will need to be addressed in the future, in order for web system evolution to be sustainable. We show that the study on websites evolution has shifted from server- to client-side, focusing on better technologies and processes, and that the users becoming creators of content open several open questions, in particular the issue of credibility of the content created and the sustainability of such resources in the long term

Developing an ecology of mind in design

The relationship between design and sustainability (DfS) is forever evolving: from the early focus on cleaner production processes and resource efficiencies to more recent endeavours to promote environmentally benign behaviours or to counter the increasing impacts of climate change. The uncomfortable truth though is that the majority of design activity serves market forces at a global scale and at an ever-increasing rate. Despite predictions of resource scarcity – peak oil, peak minerals, peak water – the increase in the linear transit of material through the Global economy rises year on year. Design straddles this production consumption cycle: it conceives of the processes and technologies that shape our artificial world; and it fashions the forms of that artificial world that drive a consumption ideology. Neither position is sustainable. Informed by Sterling’s rigorous exploration of different sustainable education paradigms, this paper reconstructs a design literacy that has the capacity to realize effective transitions for the long-term wellbeing of environment, biodiversity and humankind
