The World of Concrete trade show organizers negotiate a block of approximately 30,000 rooms with a different location each year. The case was developed through interviews with the trade show director. The issues under negotiation include the room rate, cancellation clauses, and amenities for the conference organizers and VIPs. The case is written for a negotiations course and may be used in two ways: as an intermediate exercise for refining student skills at information management and integrative bargaining or as a fairly advanced exercise about appropriate preparation for major negotiations.

ONE effect of sharing a common language with America is the imposition of a surfeit of books on matters like work study, in which our own literature is modest indeed. The almost simultaneous publication of two books with a common subject is therefore very unusual. They both deal with work measurement, one in forty‐seven chapters and the other in fifteen. Since books are not judged by a quantitative standard this is no guide to their respective merits.

The purpose of this paper is to present the prerequisites for a part-out-based spares provisioning (PBSP) programme during the phase-out of an aircraft fleet. Furthermore, associated key decision criteria are identified and a framework for the phase-out management process is presented.

Once a decision has been taken to phase-out an aircraft fleet, a number of routines for operations, maintenance and storage are affected and new tasks and functions must be introduced before initiating the actual parting-out process. A decision-making system and a management framework is needed to manage spares planning during the end-of-life phase to ensure availability at minimum cost and to ensure a manageable risk of backorders.

For PBSP programme during the phase-out of an aircraft fleet to succeed and be cost-effective, a number of linked processes, tasks and decisions are required, e.g., those included in the framework proposed in this paper (see Figure 3). A successful implementation of PBSP also requires that these processes and tasks are carried out in a timely manner and that the communications between the concerned parties are prompt, clear and direct. One experience from the studied case is that close and trustful contacts and cooperation between the operator and maintenance provider(s) will greatly facilitate the process.

Although the PBSP method is fairly commonly applied within both the military and the civilian sector, somewhat surprisingly very literature has been published on the subject. Indeed, remarkably little has been published on any aspects of maintenance during the end-of-life period.

This paper aims to reflect upon the usefulness of the word “acopia” as a diagnosis in relation to individuals in hospital.

A response to existing literature and consideration of application to practice with adults who may be vulnerable.

The term “acopia” is derived from medicine but has gained popularity throughout health and social care. It is a term that has no diagnostic tool or agreed characteristics.

Practitioners across a number of professional disciplines need to be aware of the individual circumstances, preferences and priorities of individuals to secure the most appropriate care and support for each person. Failure to acknowledge complexity of an individual’s presenting condition at hospital admission may have fatal consequences.

The importance of language used to refer to adults who are likely to be vulnerable may influence the quality of the care and treatment that they receive.

INDUSTRIALLY the two ‘in’ words today seem to be participation and consensus, the first leading to the second. How these can become a reality in modern business was discussed recently by the London Region of the Institute of Work Study Practitioners.

This study aims to perform a numerical study of air convection in a rectangular enclosure with two isothermal blocks and oscillating bottom wall temperature under laminar flow conditions. The geometry of the enclosure contains two isothermal blocks placed equidistant along the streamwise direction. The top wall is assumed to be cold (low temperature). The bottom wall temperature is either kept as constant or sinusoidally varied with time. The vertical walls are considered as adiabatic. The flow is diagonally upwards and assisted by the buoyancy force. The inlet is positioned at the bottom of the left wall, and the outlet is placed at the top of the right wall. The parameters considered in this paper are Rayleigh number (104-106), Prantdl number (0.71), amplitude of temperature oscillation (0-0.5) and the period (0.2). The effects of these parameters on heat transfer and fluid flow inside the open cavity are studied. The periodic results of fluid flow are illustrated with streamlines and the heat transfer is represented by isotherms and time-averaged Nusselt number. By virtue of increasing buoyancy, the heat transfer accelerates with an increase in the Rayleigh number. Also, the heat transfer is intensive with an increase in the bottom wall temperature.

The momentum and energy equations are solved simultaneously. The energy equation (3) is initially solved using the alternating direction implicit (ADI) method. The results of the energy equation are updated into the vorticity equation. The unsteady vorticity transport equation is also solved using the ADI method. Dimensionless time step equal to 0.01 is used for high Ra (10⁵ and 10⁶) and 0.001 is used for low Ra (10⁴). Convergence criteria of 10⁻⁵ is used during the vorticity, stream function and temperature calculations, as the sum of error should be very small.

Numerical study of air convection in a rectangular enclosure with two isothermal blocks and oscillating bottom wall temperature is performed under laminar flow condition. The effect of the isothermal blocks on the heat transfer is analyzed for different Rayleigh numbers and the following conclusions are arrived. The hydrodynamic blockage effect is subdued by the isothermal heating of square blocks. Based on the streamline diagrams, it is found that the formation of vortices is greatly influenced by the Rayleigh number when all the walls are exposed to a constant wall temperature. The influence of amplitude on the heat transfer is remarkable on the wall exposed to oscillating temperature and is subtle on the opposite static cold wall. The heat transfer increases with an increase in the Rayleigh number and temperature.

Flow is assumed to be two-dimensional and laminar subject to oscillatory boundary condition. The present investigation aims to study natural convection inside the cavity filled with air whose bottom wall is subject to time-variant temperature. The buoyancy is further intensified through two isothermal square blocks placed equidistant along the streamwise direction at mid-height.

The authors have developed a CFD solver to simulate the situation. Effect of Rayleigh number subject to oscillatory thermal boundary condition is simulated. Streamline contour and isotherm contour are presented. Local and average Nusselt numbers are presented.

There can be few who will regret the departure of 1966. As he makes his way towards that dim hall where the years are supposed to sit on their granite columns there will be few sighs at the parting. The year has been ‘a holy terror’ to almost everybody. Contraction has been its forte and uncertainty its foible. There have been severe restraints on enterprise, the crushing of many hopes and an air of apathy verging on despair. Future historians may well describe contemporary events as taking place ‘in the year of the Freeze’, much as it was once common to say ‘in the year of the French Revolution’.
