Although the 1880s are considered the beginning of the vending machine era, these devices have existed for a couple of thousand years. The earliest reference to a vending machine was made by Hero—a Greek mathematician, physicist and engineer who probably lived in Alexandria during the first century a.d.—who described and illustrated a coin-operated device to be used for vending sacrificial water in Egyptian temples. Completely automatic, the device was set in operation by the insertion of a five-drachma coin. This work traces the history of the vending machine from its inception to its current place in popular American culture, with the eight chapters covering significant eras. Successes and failures of the machines, economic factors influencing the popularity (or lack thereof) of vending machines, and the struggle of industry to become a dominant, large-scale method of retailing products are discussed. This text is richly illustrated and includes appendices on vending dollar value, vending sales by location type and vending statistics.

Practitioners in the animal welfare field, law enforcement circles, and social services arena have often maintained that childhood cruelty to animals is a forerunner to violence against people. Does this behavior serve as a red flag with respect to extremely violent offenders, such as serial killers? Is it part of the cycle of violence associated with domestic abuse? Perez and Heide provide the first scientific examination of this relationship and examine issues of cruelty across different types of animals (pet, wild, stray, farm). The authors evaluate both qualitative and quantitative data to identify correlations between childhood cruelty and adult violent behavior, utilizing interviews and criminal records of violent and nonviolent inmates in a maximum security prison. Their findings will be of importance to a diverse audience, including researchers and practitioners in the field of juvenile justice, violence and domestic abuse, social welfare, animal welfare and animal rights and developmental psychologists and counselors, as well as law enforcement officers, district attorneys and judges, county and municipal officials, animal control officers, veterinarians, and school administrators, especially those concerned with intervention and prevention strategies.
