Abstract
Purpose
This paper was written for a special issue of Kybernetes devoted to cybernetics and design. It aims to focus on case studies that are both informed by cybernetic and systems thinking and constitute a form of second‐order design praxis.
Design/methodology/approach
The case studies exemplify reflective practice as well as reporting outcomes, in terms of new understandings, from an action research process.
Findings
The paper describes what was involved in course design, from a cybernetic perspective, to effect systemic environmental decision making as well as developing and enacting a model for doing systemic inquiry (SI), which enabled situation‐improving actions to be realised in a complex, organisational setting. The paper lays out the theoretical and ethical case for understanding first‐and second‐order designing as a duality rather than a dualism.
Research limitations/implications
There is a danger that readers from an alternative epistemological position will judge the paper in terms of knowledge claims relevant only to their own epistemological position.
Practical implications
The main outcomes suggested by this paper concern the possibility of transforming the current mainstream identity of educators, project managers and researchers to a position that offers more choices through both epistemological awareness (and pluralism) and the design of learning systems, including SI, as second‐order devices.
Originality/value
The case studies are based on both novel settings and theories in action; the concept of the learning systems as both a design and systemic practice as well as an epistemological device is novel. The paper is potentially of relevance to any practitioner wishing to use systems or cybernetic thinking. It is likely to be of particular relevance to education policy makers and public sector governance.

Abstract
Introduces a special issue on globalization and the welfare state. Asserts that economic globalization constrains national economic and social policy far more now than ever before, although the level of international trade has not increased that much compared to levels at the beginning of this century. Talks about the political consequences of economic globalization, particularly welfare state retrenchment in the advanced capitalist world. Outlines the papers included in this issue – comparing welfare system changes in Sweden, the UK and the USA; urban bias in state policy‐making in Mexico; and the developing of the Israeli welfare state. Concludes that economic globalization has a limited effect in shaping social welfare policy in advanced capitalist countries; nevertheless, recommends further research into which aspects of economic globalization shape social welfare policy.

Abstract
Purpose
The purpose of this paper is to attempt an aerospaceplane design with the objective of Low-Earth-Orbit-and-Return-to-Earth (LEOARTE) under the constraints of safety, low cost, reliability, low maintenance, aircraft-like operation and environmental compatibility. Along the same lines, a “sister” point-to-point flight on Earth Suborbital Aerospaceplane is proposed.
Design/methodology/approach
The LEOARTE aerospaceplane is based on a simple design, proven low risk technology, a small payload, an aerodynamic solution to re-entry heating, the high-speed phase of the outgoing flight taking place outside the atmosphere, a propulsion system comprising turbojet and rocket engines, an Air Collection and Enrichment System (ACES) and an appropriate mission profile.
Findings
It was found that a LEOARTE aerospaceplane design subject to the specified constraints with a cost as low as 950 United States Dollars (US$) per kilogram into Low Earth Orbit (LEO) might be feasible. As indicated by a case study, a LEOARTE aerospaceplane could lead, among other activities in space, to economically viable Space-Based Solar Power (SBSP). Its “sister” Suborbital aerospaceplane design could provide high-speed, point-to-point flights on the Earth.
Practical implications
The proposed LEOARTE aerospaceplane design renders space exploitation affordable and is much safer than ever before.
Originality/value
This paper provides an alternative approach to aerospaceplane design as a result of a new aerodynamically oriented Thermal Protection System (TPS) and a, perhaps, improved ACES. This approach might initiate widespread exploitation of space and offer a solution to the high-speed “air” transportation issue.
