Firm Size and Export Intensity: Solving an Empirical Puzzle.

This paper presents a transaction costs analysis of the firm size and export intensity relationship. We submit that relation-specific investments and the costs of safeguarding these investments play a significant role in export relationships. Firm size related differences with respect to these factors are used to explain the different relationships between firm size and export intensity that have been found in previous studies. The theoretical framework is tested empirically, and support is found for different industries.

Three dimensional water vapour visualization in porous packing by near-infrared diffuse transmittance tomography

Near-infrared diffuse tomography was used in order to observe dynamic behaviour of flowing gases by measuring the 3D distributions of composition and temperature in a weakly scattering packed bed reactor, subject to wall effects and non-isothermal conditions. The technique was applied to the vapour phase hydrogen isotopic exchange reaction in a hydrophobic packing of low aspect ratio made of platinum on styrene divinyl benzene sulphonate copolymer resin. The results of tomography revealed uneven temperature and composition maps of water and deuterated water vapours in the core-packed bed and in the vicinity of the wall owing to flow maldistribution. The dynamic lag between the near-wall water vapour and deuterated water vapour compositions were observed suggesting that the convective transfer which was significant near the wall at the start, owing to high porosity, was also effective at large conversions.

Firms and Innovative Conflict Management Systems in Ireland

This article examines the practices adopted by firms in the Republic of Ireland to manage conflict involving groups of employees, focusing in particular on the uptake of 'alternative dispute resolution practices'. The article reveals that conflict management practices take the form of 'systems', and it estimates the incidence of innovative conflict management systems, incorporating alternative dispute resolution (ADR) practices, as involving about 30 per cent of firms. A series of influences are shown to be associated with innovative, ADR-based conflict management systems, especially commitment-oriented HRM practices and whether unions are recognized. © Blackwell Publishing Ltd/London School of Economics 2010.
