Sommario/riassunto |
|
Sound is produced by vibrations and as such can be dampened or augmented based on materials selection. This title looks at the effects of sound and vibration on thin structures and details how damage may be avoided, acoustical effects created, and sound levels controlled. |

Sommario/riassunto |
|
In this book, leading experts take a long-term view of the trends and policies of most relevance in achieving the structural readjustment required by the current crisis, which for too long has been viewed merely as an economic recession. A wide variety of issues are addressed, including the implications of the massive movement of wealth from advanced countries to emerging ones and the increasing income inequality evident within many countries. Prospects for growth toward the mid-century and beyond are discussed, with consideration of lessons from the past and the impact of various constraints, including corruption. The policies and reforms required to restore economic dynamism within the EU and more generally, to foster the “Good Economy” are discussed, recognizing the need for measures to promote innovation, entrepreneurship, well-being and high levels of environmental performance. The book comprises a selection of contributions presented at the XXV Villa Mondragone International Economic Seminar. For the past quarter of a century, this seminar has brought together leading experts to engage in debates on pressing economic questions. This book, based on the most recent gathering, will be of interest to all who are concerned about the challenges to growth, well-being and social inclusion that will have to be confronted in the coming decades. |
