This book looks at both the potential and limits of policies to promote entrepreneurship as an important vehicle for social mobility in Latin America and the Caribbean. Who are the region's entrepreneurs? They tend to be middle-aged males with secondary and, often, tertiary education who represent only a small segment of the economically-active population in the six countries considered in this book. They come from families in which a parent is, or was, an entrepreneur. In fact, a parent's occupation is more important in the decision to become an entrepreneur than a parent's wealth, income or |

Sommario/riassunto |
|
Working through this student-centred text readers will be brought up to speed with the modelling of control systems using Laplace, and given a solid grounding of the pivotal role of control systems across the spectrum of modern engineering. A clear, readable text is supported by numerous worked example and problems.* Key concepts and techniques introduced through applications* Introduces mathematical techniques without assuming prior knowledge* Written for the latest vocational and undergraduate courses |
