The Silent Reform of Swiss Federalism: The New Constitutional Articles on Education

This article examines the decision-making process leading to the new constitutional articles on education in Switzerland. It analyzes how actors from both state levels (Confederation and cantons) could reach consensus in a process that was prone to a "joint-decision trap". To that end, we hypothesize which factors may be conducive to a "problem-solving" style of policy-making in a compulsory negotiation system. Rich empirical material from various sources supports our theoretical arguments: We show that shared beliefs and a common frame of reference, the procedural separation between constitutional and distributional issues, neutral brokers, and informal structures were all beneficial to the success of the reform project.

Markers for silent atrial fibrillation in esophageal long-term electrocardiography.

PURPOSE Paroxysmal atrial fibrillation (PAF) often remains undiagnosed. Long-term surface ECG is used for screening, but has limitations. Esophageal ECG (eECG) allows recording high quality atrial signals, which were used to identify markers for PAF. METHODS In 50 patients (25 patients with PAF; 25 controls) an eECG and surface ECG was recorded simultaneously. Partially A-V blocked atrial runs (PBARs) were quantified, atrial signal duration in eECG was measured. RESULTS eECG revealed 1.8‰ of atrial premature beats in patients with known PAF to be PBARs with a median duration of 853ms (interquartile range (IQR) 813-1836ms) and a median atrial cycle length of 366ms (IQR 282-432ms). Even during a short recording duration of 2.1h (IQR 1.2-17.2h), PBARs occurred in 20% of PAF patients but not in controls (p=0.05). Left atrial signal duration was predictive for PAF (72% sensitivity, 80% specificity). CONCLUSIONS eECG reveals partially blocked atrial runs and prolonged left atrial signal duration - two novel surrogate markers for PAF.
