As recently as five years ago, doctors thought they had a pretty clear picture of what causes a heart attack. They saw it as a plumbing problem: too much fat in the diet builds up in the blood vessels that feed the heart, creating stoppages that starve the heart of oxygen. It was an elegant model and one that patients could understand. But it's not that simple. Cholesterol, it turns out, is just the starting point of a cascade of interlocking events. Underlying the new research presented at the American Heart Association meeting last week was a clear message: this isn't your father's heart disease anymore. 相似文献

ABSTRACTThe VW diesel emissions scandal (“dieselgate”) recounts how Volkswagen became ensnared in a self-inflicted and staggeringly costly cheating scandal that started in the U.S. and then spread to the European Union. This case study shows how fundamental differences in comparative public administration (CPA) between the U.S. and the European Union (EU) led to different consequences for one of the world’s largest and most highly-regarded European auto manufacturers with respect to four institutional variables: (a) approaches to decentralization, (b) the role of non-governmental organizations (NGOs), (c) civil (tort) law, and (d) regulatory environment. 相似文献
