Over the past ten years, the study of mobility has demonstrated groundbreaking approaches and new research patterns. These investigations criticize the concept of mobility itself, suggesting the need to merge transport and communication research, and to approach the topic with novel instruments and new methodologies. Following the debates on the role of users in shaping transport technology, new mobility research includes debates from sociology, planning, economy, geography, history, and anthropology.
This edited volume examines how users, policy-makers, and industrial managers have organized and continue to organize mobility, with a particularly attention to Europe, North America, and Asia. Taking a long-term and comparative perspective, the volume brings together thirteen chapters from the fields of urban studies, history, cultural studies, and geography. Covering a variety of countries and regions, these chapters investigate how various actors have shaped transport systems, creating models of mobility that differ along a number of dimensions, including public vs. private ownership and operation as well as individual vs. collective forms of transportation. The contributions also examine the extent to which initial models have created path dependencies in terms of technology, physical infrastructure, urban development, and cultural and behavioral preferences that limit subsequent choices.
This collection illustrates the expansiveness of an interdisciplinary approach to the study of sport. While rooted in anthropology, these essays consider American sports in their social, economic, cultural and political aspects, charting their evolution. The book draws from history, sociology, and political science; as well as considering the relationship between the developed and developing world; and culture and masculinity.
The first part of the book considers the local and global interplay of professional baseball, covering:
The second part of the book is concerned with the cultural examination of the responsiveness of masculinity to social and cultural forces, examining:

A non-technical approach to Christian Apologetics written in a narrative and conversational tone. This book approaches the topic in a very non-threatening, non-confrontational way and poses many questions that its author has confronted in his own wrestling with the truth of Christianity.

Should we really accept road trauma as collateral damage from daily road use? Eliminating Serious Injury and Death from Road Transport: A Crisis of Complacency explores why societies and their elected leaders view traffic safety as a (relatively) minor problem. It examines the changes in the culture of road use that need to occur if this public health problem is to be effectively resolved.
The book dispels the myths that currently drive societies' (misguided) view of traffic safety-the bad behavior myth and the official myth that everything that can be done is being done-and how these myths limit progress in reducing death and serious injury. It presents current scientific knowledge and draws parallels with other areas of public safety and health. The book draws on examples from the media and from public policy debates to paint a clear picture of a flawed public policy approach. It presents a model for a preventive medicine approach to traffic safety policy to get beyond an ego-centric culture to a communal safety culture.
