Some historical notes of the early stages in the development of a slender wing supersonic transport aircraft. This article recounts some of the early steps in the development of the concept of a slender wing supersonic transport aircraft during the 1960s, which ultimately led to the design of Concorde. It attempts to indicate how an advanced design problem was met successfully by a completely new approach to aerodynamic design. Since a complete history of the work would fill a large book, the approach is necessarily selective in a way intended to illustrate the development of the main aerodynamic issues.

Recently, there has been a shift toward the embodied energy assessment of buildings. However, the impact of material service life on the life-cycle embodied energy has received little attention. We aimed to address this knowledge gap, particularly in the context of the UAE and investigated the embodied energy associated with the use of concrete and other materials commonly used in residential buildings in the hot desert climate of the UAE.

Using input–output based hybrid analysis, we quantified the life-cycle embodied energy of a villa in the UAE with over 50 years of building life using the average, minimum, and maximum material service life values. Mathematical calculations were performed using MS Excel, and a detailed bill of quantities with >170 building materials and components of the villa were used for investigation.

For the base case, the initial embodied energy was 57% (7390.5 GJ), whereas the recurrent embodied energy was 43% (5,690 GJ) of the life-cycle embodied energy based on average material service life values. The proportion of the recurrent embodied energy with minimum material service life values was increased to 68% of the life-cycle embodied energy, while it dropped to 15% with maximum material service life values.

The findings provide new data to guide building construction in the UAE and show that recurrent embodied energy contributes significantly to life-cycle energy demand. Further, the study of material service life variations provides deeper insights into future building material specifications and management considerations for building maintenance.

THE end of October saw the return of most of our overseas visitors, continental and otherwise, to their homes, leaving with us pleasant memories of a mutually successful visit. The Englishman's proverbial difficulties with foreign tongues, even of neighbouring France, did not complicate matters unduly or reduce too much those interchanges which conference and school afforded. We can repeat our frequently‐expressed hope that there will be an ever increasing series of visits, both of the foreigner to England and of ourselves as foreigners to other countries. We would welcome longer stays in both cases. Nothing but good can come from them.

We provide a review of the research in this volume and suggest avenues for future research.

Review of the research in this volume and unstructured interviews with health care executives.

We identified the three central themes: (1) trust in leadership, (2) leading by example, and (3) multi-level leadership. For each of these themes, we highlight the shared concerns and findings, and provide commentary about the contribution to the literature on leadership.

While relation-oriented leadership is important in health care, there is a danger of too much emphasis on relations in an already caring profession. Moreover, in most health care organizations, leadership is distributed and scholars need to adopt the appropriate methods to investigate these multi-level phenomena.

In health care organizations, hands-on leadership, through role modeling, may be necessary to promote change. However, practicing what you preach is not as easy as it may seem.

We provide a framework for understanding current research on leadership in health care organizations.
