Abstract
We used the preceding definition to introduce our original article on resources in technology transfer that appeared in the fall 1994 issue of this publication. The emphasis is on technology transfer as a process, a series of interconnected events along a spectrum, leading from the discovery of a technology with potential value conceived in one institution up through its ultimate use by another institution. Naturally the process is frequently not a smooth one. Obstacles arise at many points along the way. These include such problems as lack of funding (by either or both parties to the process), lack of a champion to promote the technology (again in either or both parties to the process), cultural barriers within organizations, including the “not invented here” syndrome, impatience on the part of management to see quick results when it may not be possible to produce them, and lack of good information upon which to base decisions about the discovery, acquisition, adaptation, and use of technology. Clearly the technology transfer process is often expensive, protracted, and difficult.

Abstract
Surveys of corporate real estate executives in North America and elsewhere in the world indicate significant shifts in their thinking in the aftermath of the terrorist attacks on the World Trade Center and the Pentagon. Aside from the predictably much greater concern with planning for emergency escape from buildings, executives indicated that the greatest shifts in their thinking centred around issues of security of information technology and communication systems; greater use of teleconferencing and video‐conferencing (reducing travel); and more new ways of working such as homeworking, satellite and neighbourhood work centres, and hotelling. Along with such changes in practice, executives also indicated the desire to create stronger communities within their organisations, even as they also expect further to disperse their activities across locations. There is a slight shift in preference away from downtown locations and a much higher overall concern with occupancy control over the spaces that they occupy. In North America especially, there is a shift away from occupancy of high‐profile named buildings. Overall the surveys indicate that corporate real estate executives are moving ahead with distributed work‐location strategies, increasing their reliance on virtual technologies for collaboration, and re‐thinking the branding of their physical assets and the nature of community in their organisations. All of these changes further indicate the increasingly integrative role of corporate real estate within wider business strategy and a closer alignment of corporate real estate activities with human resources, organisational development and information technology.

Abstract
Purpose
The study seeks to investigate the mechanisms for the effects of environmental design features of a green building on occupants' environmental awareness (EA) and organizational image (OI).
Design/methodology/approach
One mechanism investigated the direct effects of environmental design features of a green building on occupants' EA and OI. The other mechanism investigated the indirect effects on occupants' EA and OI resulting from the direct effects of environmental design features on occupants' workplace satisfaction. The data were collected from 175 occupants of the Leadership in Energy and Environmental Design (LEED)‐certified green building using a questionnaire instrument.
Findings
Based on frequency, correlational, and regression analyses of the data, the study found no evidence for direct effects of environmental design features on occupants' EA and OI. The study, however, found some evidence for indirect effects, indicating that individual workspace and departmental space features affected occupants' satisfaction with individual workspaces and the building, which then affected occupants' EA and OI.
Research limitations/implications
The study involved only the employees of an organization who occupy a single LEED‐certified green building. Future studies should involve a larger sample of green buildings. Future studies should also involve other stakeholders of these buildings.
Practical implications
The study is important for the long‐term market growth of green buildings, because it provides supporting evidence for the organizational leaders who want to use green buildings to enhance organizational values and benefits.
Originality/value
The study makes an original contribution to the field, because studies focusing on the potential links between green buildings and organizational benefits and values, and the mechanisms that may help explain these links are still rare.

Abstract
Purpose
Today’s modern liquid propellant rocket engines have a very complicated structure. They cannot be arbitrarily downsized, ensuring efficient propellants’ mixing and combustion. Moreover, the thermodynamic cycle’s efficiency is relatively low. Utilizing detonation instead of deflagration could lead to a significant reduction of engine chamber dimensions and mass. Nowadays, laboratory research is conducted in the field of rotating detonation engine (RDE) testing worldwide. The aim of this paper is to cover the design of a flight demonstrator utilizing rocket RDE technology.
Design/methodology/approach
It presents the key project iterations made during the design of the gaseous oxygen and methane-propelled rocket. One of the main goals was to develop a rocket that could be fully recoverable. The recovery module uses a parachute assembly. The paper describes the rocket’s main subsystems. Moreover, vehicle visualizations are presented. Simple performance estimations are also shown.
Findings
This paper shows that the development of a small, open-structure, rocket RDE-powered vehicle is feasible.
Research limitations/implications
Flight propulsion system experimentation is on-going. However, first tests were conducted with lower propellant feeding pressures than required for the first launch.
Practical implications
Importantly, the vehicle can be a test platform for a variety of technologies. The rocket’s possible further development, including educational use, is proposed.
Originality/value
Up-to-date, no information about any flying vehicles using RDE propulsion systems can be found. If successful in-flight experimentation was conducted, it would be a major milestone in the development of next-generation propulsion systems.

Abstract
Purpose
The purpose of this paper is to consider relative navigation – a vital technology to satellites formation flying, and to propose a new concept for relative navigation determination along with a technical approach for its practical implementation.
Design/methodology/approach
The determination of relative orbit is considered with the relative distance elevation and azimuth measurements about formation flying while the primary satellite is in a circle or ellipse orbit. This measurement is obtained by laser range finder and the estimations of the intersatellite relative position and velocity are obtained by utilizing the unscented Kalman filter instead of extended Kalman filter.
Findings
The simulation results show that the error of the relative position and velocity can be estimated with the order of cm and mm/s, respectively, under the effect of J2, converge faster than EKF, and then demonstrate that the approach is feasible.
Originality/value
The paper proposes a new concept for relative navigation determination and describes a technical approach for its practical implementation.

Abstract
This paper reviews and analyses some specific conditions for innovation in the European space sector. Innovation has enabled the first steps of humans into space and remained a key central parameter ever since. On the other hand, the space sector lacks key parameters encouraging innovation. While governments have put in place instruments to overcome these deficiencies, the current mechanisms seem to address mainly incremental/sustaining innovation. It is argued that this situation might be leaving the space sector prone to changes coming from radical and disruptive innovation. Applying mechanisms developed for understanding disruptive innovation processes in the private sector, two specific current developments in the space sector are analyzed.
