Why do empires build walls and fences? Are they for defensive purposes only, to keep the 'barbarians' at the gate; or do they also function as complex offensive military structures to subjugate and control the colonised? In Empires and Walls, Mohammad A. Chaichian meticulously examines the rise and fall of the walls that are no longer around; as well as the impending fate of 'neo-liberal' barriers that imperial and colonial powers have erected in the new Millennium. Chaichian provides evidence that walls always signal the fading power of an empire.

The booming 1990s saw a new demographic pattern emerging in the United States the shift of immigrants toward smaller towns and metropolitan areas in ethnically homogenous (or traditionally bicultural) areas. These places offer growing, specialized economies in need of unskilled or semi-skilled (and occasionally skilled) labor; they also offer, for some immigrants, a favorable physical and social climate. Immigrants Outside Megalopolis documents this trend with case studies including Hmong in Wisconsin, Iranians in Iowa, Mexicans in Kansas and Colorado, Vietnamese in coastal Louisiana, Mexicans in North Carolina and south Texas, Cubans in Arizona, Bosnians in upstate New York, Asian Indians in north Texas, and Ukranians and Russians in the Willamette Valley of Oregon. Truly, this process is resulting in a cultural transformation of the U.S. heartland. The implantation of new features on the cultural landscape (businesses, homes, churches, schools, possessions, and the peoples themselves) is giving many Americans a world geography lesson at a time when increased world understanding is something the country cannot do without. This geography lesson comes at a cost, however: the difficult process of social adjustment, playing out on a daily basis between immigrant and host populations, which remains largely unresolved. This process is an important focus of Jones's book."
