Book Description
This publication is a revised and updated version of World Soil Resources Reports No. 84 and 103 and presents the international soil classification system. Every soil in the world can be allocated to one of the 32 Reference Soil Groups as defined in this document, and can further be characterized by a set of qualifiers. The resulting soil name provides information on soil genesis, soil ecological function and soil properties relevant for land use and management. The same system, refined slightly, may be used to name the units of soil map legends, thereby providing comprehensive spatial information. By accommodating national soil classification systems, the World Reference Base facilitates the worldwide correlation of soil information.

Book Description
In the United States, some populations suffer from far greater disparities in health than others. Those disparities are caused not only by fundamental differences in health status across segments of the population, but also because of inequities in factors that impact health status, so-called determinants of health. Only part of an individual's health status depends on his or her behavior and choice; community-wide problems like poverty, unemployment, poor education, inadequate housing, poor public transportation, interpersonal violence, and decaying neighborhoods also contribute to health inequities, as well as the historic and ongoing interplay of structures, policies, and norms that shape lives. When these factors are not optimal in a community, it does not mean they are intractable: such inequities can be mitigated by social policies that can shape health in powerful ways. Communities in Action: Pathways to Health Equity seeks to delineate the causes of and the solutions to health inequities in the United States. This report focuses on what communities can do to promote health equity, what actions are needed by the many and varied stakeholders that are part of communities or support them, as well as the root causes and structural barriers that need to be overcome.

Book Description
Often thought of as a primitive backwoods peopled by rough hunters and unsavory characters, early Arkansas was actually productive and dynamic in the same manner as other American territories and states. In this, the second volume in the Histories of Arkansas, S. Charles Bolton describes the emigration, mostly from other southern states, that carried Americans into Arkansas; the growth of an agricultural economy based on cotton, corn, and pork; the dominance of evangelical religion; and the way in which women coped with the frontier and made their own contributions toward its improvement. He closely compares the actual lifestyles of the settlers with the popularly held, uncomplimentary image. Separate chapters deal with slavery and the lives of the slaves and with Indian affairs, particularly the dispossession of the native Quapaws and the later-arriving Cherokees. Political chapters explore opportunism in Arkansas Territory, the rise of the Democratic Party under the control of the Sevier-Johnson group known as the Dynasty, and the forces that led Arkansas to secede from the Union. In addition, Arkansas’s role in the Mexican War and the California gold rush is treated in detail. In truth, geographic isolation and a rugged terrain did keep Arkansas underpopulated, and political violence and a disastrous experience in state banking tarnished its reputation, but the state still developed rapidly and successfully in this period, playing an important role on the southwestern frontier.

Book Description
As the importance and dependence of specific mineral commodities increase, so does concern about their supply. The United States is currently 100 percent reliant on foreign sources for 20 mineral commodities and imports the majority of its supply of more than 50 mineral commodities. Mineral commodities that have important uses and face potential supply disruption are critical to American economic and national security. However, a mineral commodity's importance and the nature of its supply chain can change with time; a mineral commodity that may not have been considered critical 25 years ago may be critical today, and one considered critical today may not be so in the future. The U.S. Geological Survey has produced this volume to describe a select group of mineral commodities currently critical to our economy and security. For each mineral commodity covered, the authors provide a comprehensive look at (1) the commodity's use; (2) the geology and global distribution of the mineral deposit types that account for the present and possible future supply of the commodity; (3) the current status of production, reserves, and resources in the United States and globally; and (4) environmental considerations related to the commodity's production from different types of mineral deposits. The volume describes U.S. critical mineral resources in a global context, for no country can be self-sufficient for all its mineral commodity needs, and the United States will always rely on global mineral commodity supply chains. This volume provides the scientific understanding of critical mineral resources required for informed decisionmaking by those responsible for ensuring that the United States has a secure and sustainable supply of mineral commodities.
