Provides an introduction to the theory of jet bundles for mathematicians and physicists who wish to study differential equations.

The theme of this book is modeling the real world using mathematics. The authors concentrate on the techniques used to set up mathematical models and describe many systems in full detail, covering both differential and difference equations in depth. Among the broad spectrum of topics studied in this book are: mechanics, genetics, thermal physics, economics and population studies.

This book is a detailed examination of the demographic policy of Mussolini's Fascist regime. Based on archival research, it examines both the Italian statistics, and the demographic theory of the time. The author shows how the Fascists used statistics to mold public opinion through propaganda, as well as to form policy. He describes their program to increase the population in Italy, and reveals what the policy behind this program tells us about the contradictory nature of Fascism itself--it was at the same time modern and antimodern, revolutionary and reactionary.

John Broad explores the rise and fall of the Verney family of Middle Claydon, Buckinghamshire, demonstrating the family's rise to wealth as motivated by a strong dynastic imperative. He reveals how the family managed its estates to maximize income and used its wealth to transform the Claydon villages and landscape, creating a pattern of "open" and "closed" parishes. Based on the formidable Verney family archive with its abundant correspondence, this book will appeal to anyone interested in the English countryside as a dynamic force in English social, economic and demographic history.
