A failsafe analysis using NASTRAN's piecewise linear analysis and a nine node linear crack element

A two-dimensional crack element was implemented into NASTRAN as a user dummy element and used to study failsafe characteristics of the C5A fuselage. The element is formulated from Reitsner's functional requiring that it satisfy compatability with the linear boundary displacement elements in NASTRAN. Its accuracy is demonstrated by analyzing for the stress intensity factors of two simple crack configurations for which there are classic solutions

Corporate governance and employment relations

Using the 2004 United Kingdom Workplace Employment Relations Survey (WERS 2004), this paper examines the impact of corporate governance on HRM practices and employment relations outcomes within organizations in the UK. The analysis suggests that when a remote external stake-holder is assigned dominance, particularly in the case where their liability is limited and the organization is large, the conditioning of managerial commitments on the requirements of the dominant stake-holder has the potential to undermine the effectiveness of the HRM system in achieving its objectives

Work intensification and employment insecurity in professional work

Professional work is a category of employment that has traditionally been associated with high levels of worker autonomy, economic and social status. During the past decade, changes in customer expectations, government policy and technology have generated pressures resulting in enhancement of the quality and efficiency of service provision, expansion in task requirements and a need for higher levels of discretion. In this sense, professional work has been upgraded. However, the changes have also led to a deterioration in the economic and social status of professional work, adversely impacting on the social and psychological well-being of professional workers. This paper examines these developments in five professions including two established professions (lawyers and pharmacists), one aspiring profession (midwives) and two emerging professions (counselling psychologists and human resource managers). The empirical findings are based on a survey of 1270 professional workers conducted in 2000 and 2001

Partnership in practice

This paper examines human resource management practices adopted in a group of eight case study firms and their tendencies towards versus away from partnership. The analysis is based on data collected during interviews with 124 employees (75 in organisations tending towards partnership and 49 in organisations tending away from partnership) and senior managers, conducted in 1997-1998 for the Job Insecurity and Work Intensification Survey (JIWIS). Drawing on the perspectives of senior managers and employees, we examine the tendency of firms towards and away from partnership in employment relations; and in keeping with the JIWIS methodology (Burchell et.al., 2001) we combine quantitative and qualitative evidence in our analysis. Specifically, we are interested in what partnership looks like in these different contexts, the reasons it is pursued (or not), the degree to which companies have been successful in achieving their partnership objectives (from the perspective of both management and employees), and the conditions that have either facilitated or impeded partnership in relationships with employees

Comparison of hot wire/laser velocimeter turbulence intensity measurements

The question of whether a random measure of particle velocities yields a good statistical estimate of the stationary condition of the turbulence flow field was investigated by comparing hot-wire and laser velocimeter turbulence intensity measurements. Great care was taken to insure that the instrument precision of both the laser velocimeter and hot wire was maximized. In this attempt to reduce the measurement uncertainties in the hot wire, direct digitization of the analog output signal was performed with point-by-point conversion to velocity through a spline fit calibration curve and the turbulence intensity function was calculated statistically. Frequent calibrations of the hot wire were performed using the laser velocimeter as the velocity standard to account for the presence of the small seed particles in the air flow and signal drift in the hot wire

Anglo-American corporate governance and the employment relationship: a case to answer

The corporate governance environment in the UK and US is generally thought to be hostile to the emergence of cooperative employment relations of the kind exemplified by labour-management partnerships. We discuss case study evidence from the UK which suggests that, contrary to this widespread perception, enduring and proactive partnerships may develop, in conditions where management can convince shareholders of the long-term gains from this approach, and where other regulatory factors operate to extend the time-horizon for financial returns. We conclude that there is more scope than is commonly allowed for measures which could reconcile liquidity in capital markets with cooperation in labour relations

Corporate governance, stakeholding and the nature of employment relations within the firm

This paper investigates the effect of different forms of corporate governance on the structure and nature of stakeholder relationships within organizations and the consequent impact on employment relations within the firm. In this, HRM assumes a dual role in delivering improvements in production efficiency and in fostering employee commitment to the organization and its objectives. However, different forms of corporate governance prioritise stakeholder interests in ways that may bring these two objectives into conflict. To address these questions, we examine the interrelationship between corporate governance, HRM practices and HRM outcomes in a comparative analysis of companies operating under alternative forms of governance, including private sector, public sector and family-owned firms. The empirical analysis is based on the UK Work and Employment Relations Survey (WERS98)

Absorption of Energy at a Metallic Surface due to a Normal Electric Field

The effect of an oscillating electric field normal to a metallic surface may be described by an effective potential. This induced potential is calculated using semiclassical variants of the random phase approximation (RPA). Results are obtained for both ballistic and diffusive electron motion, and for two and three dimensional systems. The potential induced within the surface causes absorption of energy. The results are applied to the absorption of radiation by small metal spheres and discs. They improve upon an earlier treatment which used the Thomas-Fermi approximation for the effective potential.Comment: 19 pages (Plain TeX), 2 figures, 1 table (Postscript

The export of national varieties of capitalism: the cases of Wal-Mart and Ikea

Using the cases of Wal-Mart and IKEA, this paper takes a productive systems approach to examine ‘varieties of capitalism’ from the perspective of the ways by which production and market relations are structured and prioritised. It considers the nature of these relations and their interaction within the domestic economy and the ways that firms and national systems interact with each other in the global economy. It examines the processes by which trading standards are transported via supply chain relationships, which ultimately become embedded in products and recognized by consumers at various stages. In this analysis, the cases of Wal-Mart and IKEA provide insight into the ways by which national systems extend themselves globally, their contrasting effects on the business environments in host localities, and the impact of the resulting supply chain relations on organizational performance

NASTRAN used in a production environment

A finite element analysis procedure built around the NASTRAN system is assessed. A number of support programs that were either written or modified to interface with NASTRAN and some improvements that were made to NASTRAN itself are noted. Some typical models are analyzed and an actual schedule is followed for constructing and analyzing the models to support a large design program
