Performance after mass privatisation : the case of Slovenia

Initial ownership structures resulting from the mass privatisation programme were intended as transitional, whereas optimal would be set up gradually and would result from secondary transactions. Therefore, mass privatisation is typically considered successful if secondary transactions lead to improved ownership, in particular, with emergence of strategic investors. If this approach is correct, positive effects of mass privatisation are thus not shown only by companies remaining in control of initial owners but mostly by the companies that have already gone through secondary privatisation. Accordingly, the success of secondary sales is to be evaluated by how successfully companies perform after the sale to new owners. This paper attempts to verify empirically those assumptions. The econometric analysis of panel data, after correcting for a selection bias, shows that TFP (total factor productivity) growth is highest in public companies. In addition we found that the secondary privatisation has had practically no positive effect on economic efficiency in the period 1995-99. We interpret these results as supporting evidence for the theoretical approach, which argues that the impact of strategic investors on performance may be ambiguous and that the quality of the capital market institutions is more important than ownership effects. The former creates incentives for performance by increasing the cost of expropriation of minority shareholders

This special issue of the Journal of Membrane Biology contains reports on recent developments in the field of electroporation by participants in the International Workshop and Postgraduate Course on Electroporation-Based Technologies and Treatments held in November 2014 in Ljubljana. This was the eighth session of what is now an annual event, first organized in 2003

Introduction to Fourth Special Issue on Electroporation-Based Technologies and Treatments

This fourth special electroporation-based technologies and treatments issue of the Journal of Membrane Biology contains reports on recent developments in the field of electroporation by participants in the 7th International Workshop and Postgraduate Course on electroporation based technologies and treatments (EBTT 2013) held in Ljubljana, November 17–23, 2013. The 65 participants included faculty members, invited lecturers, special guests, and young scientists, and students from 16 countries. In addition to lectures on the fundamentals, this year’s sessions included talks on microbial inactivation by pulsed electric fields, modeling of intracellular electroporation, electroporation in food processing, and electrotransfer-facilitated DNA vaccination

Effect of Contact Force on Pulsed Field Ablation Lesions in Porcine Cardiac Tissue.

BACKGROUND Contact force has been used to titrate lesion formation for radiofrequency ablation. Pulsed Field Ablation (PFA) is a field-based ablation technology for which limited evidence on the impact of contact force on lesion size is available. METHODS Porcine hearts (n=6) were perfused using a modified Langendorff set-up. A prototype focal PFA catheter attached to a force gauge was held perpendicular to the epicardium and lowered until contact was made. Contact force was recorded during each PFA delivery. Matured lesions were cross-sectioned, stained, and the lesion dimensions measured. RESULTS A total of 82 lesions were evaluated with contact forces between 1.3 g and 48.6 g. Mean lesion depth was 4.8 ± 0.9 mm (standard deviation), mean lesion width was 9.1 ± 1.3 mm and mean lesion volume was 217.0. ± 96.6 mm3 . Linear regression curves showed an increase of only 0.01 mm in depth (Depth = 0.01*Contact Force + 4.41, R2 = 0.05), 0.03 mm in width (Width = 0.03*Contact Force + 8.26, R2 = 0.13) for each additional gram of contact force, and 2.20 mm3 in volume (Volume = 2.20*Contact Force + 162, R2 = 0.10). CONCLUSIONS Increasing contact force using a bipolar, biphasic focal PFA system has minimal effects on acute lesion dimensions in an isolated porcine heart model and achieving tissue contact is more important than the force with which that contact is made.
