Grasses and grasslands are of increasing interest to conservationists, biologists, and gardeners. There are more than 300 species of native California grasses and they are found in almost every climate--from cool, wet forests to hot, dry deserts. Native grasses are also important in land restoration, as they improve soil quality, increase water infiltration, and recycle nutrients. Their deep roots can tap soil water, allowing them to stay green year-round and act as fire buffers around residences. Native grasses also provide vital habitat to many species of insects, birds, reptiles, and mammals. Despite all of this, grasslands remain one of the most underprotected of California's vegetation types, and native grasslands have undergone the greatest percentage loss of any habitat type in the state. Grasses are also among the most difficult plants to identify. Organized alphabetically, Field Guide to Grasses of California covers the more common native and naturalized grasses, and features over 180 color illustrations to help identify them.
This collection of original essays brings econometric theory to bear on the problem of estimating the labor force participation of women. Five scholars here examine, both theoretically and empirically, the determinants of women's wages in the market, the value of their home time, and the factors that affect their employment. Originally published in 1980. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These paperback editions preserve the original texts of these important books while presenting them in durable paperback editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

The population of Asia is growing both larger and older.
Demographically the most important continent on the world, Asia's
population, currently estimated to be 4.2 billion, is expected to
increase to about 5.9 billion by 2050. Rapid declines in fertility,
together with rising life expectancy, are altering the age
structure of the population so that in 2050, for the first time in
history, there will be roughly as many people in Asia over the age
of 65 as under the age of 15.
This book sheds light on one of the most controversial issues of the decade. It identifies the economic gains and losses from immigration?for the nation, states, and local areas?and provides a foundation for public discussion and policymaking. Three key questions are explored: What is the influence of immigration on the overall economy, especially national and regional labor markets? What are the overall effects of immigration on federal, state, and local government budgets? What effects will immigration have on the future size and makeup of the nation's population over the next 50 years? The New Americans examines what immigrants gain by coming to the United States and what they contribute to the country, the skills of immigrants and those of native-born Americans, the experiences of immigrant women and other groups, and much more. It offers examples of how to measure the impact of immigration on government revenues and expenditures?estimating one year's fiscal impact in California, New Jersey, and the United States and projecting the long-run fiscal effects on government revenues and expenditures. Also included is background information on immigration policies and practices and data on where immigrants come from, what they do in America, and how they will change the nation's social fabric in the decades to come.
