Universal design (UD) is a rising global trend and can be related to social sustainable development (SSD), which has gained increasing recognition in the political arena and in the corporate world. UD targets needs, social participation and access to goods and services by the widest possible range of users. For this reason, it is vital to consider the inclusion and advancement of persons who have been excluded from interacting in society for different reasons. Design is often associated with making good looking, expensive products. However, as the Rio Declaration stated in 2005, designers can also contribute to better life-quality in society and UD can work as a catalyst for this advancement. The goal of this paper is to show how UD can be related to SSD and discuss how far it presents a fruitful methodological approach for SSD. Knowledge generation in these areas means here not analyzing new approaches in one of the fields but exploring the so far uncharted cooperation possibilities of both. For that reason, the paper discusses common goals of UD and SSD by considering relevant theories in both fields. Further, methods in the UD process are examined directed at these goals. Finally, some examples and conclusions are presented as to how designers contribute with inclusive and socially sustainable solutions and how insights from UD can be used for interplay with SSD in research and practice.

Abstract:The Sustainable Development Goals (SDGs), like the sustainable development (SD) concept itself, are open to multifaceted interpretations, and the same is true for their ethical implications. While SDG values are widely accepted as universal, the ethical structure of the SDGs is complex, with differing interpretations and ideas, e.g., on how to regard and value nature. This article is a conceptual attempt to clarify and structure ethical interpretations based on an environmental ethics framework consisting of two branches: anthropocentrism and biocentrism. The aim is to provide an overview of SDG positions and locate them in the wider field of environmental ethics, addressing the human-nature relationship as a recurring topic in the SDGs. Section 1 of this article presents environmental ethics and briefly discusses anthropocentrism and biocentrism. Section 2 outlines ethical similarities of SD and the SDGs and locates representative SDG interpretations within the environmental ethics framework. Section 3 summarizes findings and suggests a possibility of integrating biocentrism and anthropocentrism with regard to the further interpretation and discussion of SDG ethics. Insights from this article will aid researchers in adopting a better overview on ethical positions in the SDG debate.

Business research is placing increasing focus on the relationship between the natural environment and the political concept of sustainable development. Within this nexus, one area, labelled 'Corporate Sustainability', emphasizes the interactions between economic, environmental and social values. The need to consider multiple values has contributed to a blur in the conceptual landscape. This is partly due to the fact that authors often address epistemological challenges on an implicit level. Moreover, hidden ideologies, e.g. the profit maximization paradigm, can explain the conceptual obscurity.The contribution of this article is twofold. Firstly, a conceptual framework is developed based on the dichotomy of positivism and constructivism. A relation is established between these epistemological positions and the analytic treatment of environmental and social values. The framework can be applied to increase transparency on epistemological challenges and thereby strengthening construct validity in the field. Secondly, an analysis of the most influential literature from the last 50 years shows that there is a trend of clustering theoretical positions and value constructs without any critical awareness of their philosophical assumptions. The authors hope that acknowledgement of a multi-paradigmatic approach can help to clarify the epistemology of the research area by establishing pluralism as an explicit position.

Research linking design to sustainability surfaced in the 1970s and has since received broad attention in academic and professional literature. Rachel Carson's book Silent Spring from 1962 and the Gaia hypothesis of James Lovelock and Lynn Margulis from 1974 inspired design, among many other disciplines, to search for an appropriate balance between industrial cultures and natural surroundings. This article tracks a brief idea-historical account of sustainable design theories. Main concepts in the field are consolidated under three criteria: ethics, technology fixes and social interaction. These criteria are considered as the main motivators for research and theory development in sustainable design. Following the Introduction, which gives an overview of concept development in design in general and sustainable design in particular, the second section explains the methodological onset for the analysis and introduces three concepts that represent important trends in sustainable design theory. The three concepts: Papanek's socially and ecologically responsible design, the Design for the Environment approach, and Manzini's sustainable everyday philosophy, are analysed in the third section according to the role they assign to the criteria. Further, the section reviews the concepts within a wider debate on sustainable development. The article concludes with a proposal as to how conceptualization in sustainable design could proceed, to meet the complexity of sustainability issues in present society.

Service providers world-wide are facing challenges of network operations, management, security, quality of service and address deficiency problem while the current world network still run with the existing legacy system. The issues of address shortage including the problems of legacy IPv4 address have been resolved with the advancement on IPv6 addresses. Similarly the increasing complexities of networking management have also been addressed by the advancement on Software Defined Network (SDN). For the future sustainability, service providers have to migrate their existing network to newer technologies. This requires upgrades on or replacement of existing networking devices that are operating on real time. But the lack of sufficient cost, technical human resources and suitable migration plan are becoming the major challenges for the fairly sustained service providers to migrate their existing network into next generation programmable network.SDN and IPv6 are the two new paradigms in networking operation and management that jointly after migration addresses all the existing issues of current networking system. In this paper, we present a greedy algorithm to identify the migration cost of network devices in the optimal path based on customer demand for incremental adoption of SDN enabled IPv6 network. We justify that a unified migration approach to SDN and IPv6 network would help to reduce the total cost of migration. We also verify that sequence of migration considering customer demand and cost constraints give the good estimation for unified migration to Software Defined IPv6 (SoDIP6) network.
