Impact of Clusters on Regional Economic Performance : a Methodological Investigation and Application in the Case of the Precision Goods Sector in Switzerland

Resbeut, Mathieu ; Gugler, Philippe

In: Competitiveness Review, 2016, vol. 26, no. 2, p. 188-209

Purpose – This paper aims to examine the methodology used to identify clusters on the one hand and assess the economic impact that those may have on regions on the other hand. Design/methodology/approach – The influential work on “clusters”lead by Michael Porter since the 1990s has become a tool for promoting innovation and growth at national and regional level. Even if the theory has...

Auditor expertise : Evidence from the public sector

Schelker, Mark

In: Economics Letters, 2012, vol. 116, no. 3, p. 432-435

This paper is the first attempt to study the relationship between public auditor expertise and fiscal performance. I find that states requiring the auditor to hold a professional degree feature significantly higher credit ratings and lower expenditures and debt.

Auditors and Corporate Governance : Evidence from the Public Sector

Schelker, Mark

In: KYKLOS, 2013, vol. 66, no. 2, p. 275-300

Corporate auditors review and evaluate financial statements. To enhance independence the selection process and mandatory auditor rotation requirements have been debated intensively. The available empirical evidence is not conclusive and suffers from serious endogeneity problems. We propose learning from the public sector in which auditors play a similar role and present empirical evidence on...

Geochemical fingerprinting of key lithologies and depositional processes across the upper boundary of the Opalinus Clay (Aalenian, Middle Jurassic, northern Switzerland)

Lauper, Bruno ; Deplazes, Gaudenz ; Vogel, Hendrik ; Jaeggi, David ; Wohlwend, Stephan ; Ariztegui, Daniel ; Foubert, Anneleen

In: The Depositional Record, 2021, vol. 7, no. 1, p. 25-51

The Opalinus Clay is an argillaceous to silty mudstone formation, notable in Switzerland as the selected host rock for deep geological disposal of radioactive waste. Its upper bounding unit (Passwang Formation and eastern equivalents) is composed of successions of mudstone, sandy bioclastic marl and limestone separated by ooidal ironstone beds. The lithostratigraphic transition is diachronous...

Protein complexes and neighborhoods driving autophagy

Siva Sankar, Devanarayanan ; Dengjel, Jörn

In: Autophagy, 2020, vol. 0, no. 0, p. 1–17

Autophagy summarizes evolutionarily conserved, intracellular degradation processes targeting cytoplasmic material for lysosomal degradation. These encompass constitutive processes as well as stress responses, which are often found dysregulated in diseases. Autophagy pathways help in the clearance of damaged organelles, protein aggregates and macromolecules, mediating their recycling and ...
