Presents 35 abstracts from the 2001 Employment Research Unit Annual conference held at Cardiff Business School in September 2001. Attempts to explore the theme of changing politics of employment relations beyond and within the nation state, against a background of concern in the developed economies at the erosion of relatively advanced conditions of work and social welfare through increasing competition and international agitation for more effective global labour standards. Divides this concept into two areas, addressing the erosion of employment standards through processes of restructuring and examining attempts by governments, trade unions and agencies to re‐create effective systems of regulation. Gives case examples from areas such as India, Wales, London, Ireland, South Africa, Europe and Japan. Covers subjects such as the Disability Discrimination Act, minimum wage, training, contract workers and managing change.

Presents three non‐isothermal, time dependent, three dimensional examples having cylindrical geometries to show the significant effort of numerical precision and dissipation on rotating flow predictions. The examples are relevant to turbomachinery design and geophysical studies. Discusses the relationship between numerical precision, numerical dissipation and co‐ordinate system angular velocity. Compares predictions made in stationary and rotating co‐ordinate systems, using contour plots of dimensionless stream function and temperature. Shows that wrong, axisymmetric solutions are predicted if the co‐ordinate system is not selected to minimize relative tangential velocities/Peclet numbers, thereby increasing numerical precision and reducing dissipation.

Regardless of the size of the firm, the sector of the transportation industry or the style of management, distribution runs on information. The sheer size and volume of today's distribution activities require a high degree of commitment to computer‐based technologies to support managerial decisions on a continuous basis.

In Part 1 the authors dealt with the background of tribology and its intended purpose, ie to conserve energy by minimization of wear and friction in moving parts of plant and machinery — the basis of the 1966 Jost Report. In Part 2 they set out to show in great detail how this may be achieved dramatically by intensive research and development.

“Tribological Design — The Power Generation Industry”, was an invited paper presented at the 15th Leeds‐Lyon Symposium held in Leeds in 1988. A review of the proceedings published last autumn appeared in the last issue of Industrial Lubrication and Tribology.

The ‘Decollectivisation of Industrial Relations’ is now a significant theme in the policy of the Conservative Government and that of a growing, if still small number, of companies and state agencies. Its theoretical justification is a ‘neo‐ classical’ economic perspective in which the contract of employment is conceived as a market relationship between symmetrical parties and organisations of capital and labour are differently evaluated. The collective nature of the former is subsumed under its legal individual personality and only certain monopolies and monopoly practices are considered illegitimate. Unions, however, are viewed as coercive organisations which intrude upon the contract of employment to distort the labour market through the imposition of a ‘rent’ upon the hire of labour by capital; as a result, either labour costs are raised and profits reduced or the wages of non‐union labour are suppressed. The neo‐classical perspective is thus hostile to collective power of unions as such rather than ‘excesses’ of that power which could be redressed by ‘shifting the balance’ to employers as was the stated objective of the Employment Act 1980 (Wedderburn 1989).

Unquestionably, the appraisal interview is a significant part of the performance appraisal process. It is in this formal interview that feedback on subordinate performance is communicated, salary/promotion discussions are held, ways of correcting performance deficiencies are discussed, training and development needs are explored, and future work goals and objectives are delineated (Eichel & Bender, 1984; Pratt, 1985).

This paper aims to present the optimum two-plane discrete balancing procedure for rigid rotor. The discrete two-plane balancing in which rotor is balanced to minimize the residual effects or the reactions on the bearing supports using discrete parameters such as masses and their angular positions on two balancing planes.

Therefore as a multi-objective optimization problem is formulated by considering reaction forces on the bearing supports as a multi objective functions and discrete parameters on each balancing plane as design variables. These multi-objective functions are converted into a single-objective function using appropriate weighting factors. Further, this optimization problem is solved using discrete optimization algorithm, based on Jaya algorithm.

The performance of the discrete Jaya algorithm is compared to genetic algorithm (GA) algorithm. It is found that Jaya algorithm is computationally more efficient than GA algorithm. A number of masses per plane are used to balance the rotor. A comparison of reaction forces using number of masses per plane is investigated.

The effectiveness of the proposed methodology is tested by the balancing problem of rotor available in the literature. The influence of a number of balance masses on bearing forces and objective function are discussed. ADAMS software is used for validation of a developed balancing approach.
