The rapid conversion of land to urban and suburban areas has profoundly altered how water flows during and following storm events, putting higher volumes of water and more pollutants into the nation's rivers, lakes, and estuaries. These changes have degraded water quality and habitat in virtually every urban stream system. The Clean Water Act regulatory framework for addressing sewage and industrial wastes is not well suited to the more difficult problem of stormwater discharges. This book calls for an entirely new permitting structure that would put authority and accountability for stormwater discharges at the municipal level. A number of additional actions, such as conserving natural areas, reducing hard surface cover (e.g., roads and parking lots), and retrofitting urban areas with features that hold and treat stormwater, are recommended.

The purpose of the United Nations International Comparison Project (ICP) is to compare the purchasing power of currencies and the real gross domestic product (GDP) per capita of different countries. It is well known that the usual method of converting the GDPs of different countries to a common currency, usually U.S. dollars, at existing exchange rates is misleading because exchange rates do not necessarily reflect the purchasing power of currencies. The ICP has found that the purchasing power of a country's currency over GDP can be as much as three times its dollar exchange rate, and thus the real GDP per capita is three times the value shown in an exchange-rate conversion. The unsatisfactory nature of exchange-rate conversions has become even clearer in the past few years under the new regime of managed floating rates. Changes in exchange rates of as much as 20 percent within the space of a year have not been unusual even among major currencies.

In the history of electronic communication, the last quarter of the nineteenth century holds a special place, for it was during this period that the telephone, phonograph, electric light, wireless, and cinema were all invented. In When old Technologies Were New, Carolyn Marvin explores how two of these new inventions--the telephone and the electric light--were publicly envisioned at the end of the nineteenth century, as seen in specialized engineering journals and popular media. Marvin pays particular attention to the telephone, describing how it disrupted established social relations, unsettling customary ways of dividing the private person and family from the more public setting of the community. On the lighter side, she describes how people spoke louder when calling long distance, and how they worried about catching contagious diseases over the phone. A particularly powerful chapter deals with telephonic precursors of radio broadcasting--the "Telephone Herald" in New York and the "Telefon Hirmondo" of Hungary--and the conflict between the technological development of broadcasting and the attempt to impose a homogenous, ethnocentric variant of Anglo-Saxon culture on the public. While focusing on the way professionals in the electronics field tried to control the new media, Marvin also illuminates the broader social impact, presenting a wide-ranging, informative, and entertaining account of the early years of electronic media.

A collection of United Nations documents associated with the drafting of the Universal Declaration of Human Rights, these volumes facilitate research into the scope of, meaning of and intent behind the instrument's provisions. It permits an examination of the various drafts of what became the thirty articles of the Declaration, including one of the earliest documents – a compilation of human rights provisions from national constitutions, organised thematically. The documents are organised chronologically and thorough thematic indexing facilitates research into the origins of specific rights and norms. It is also annotated in order to provide information relating to names, places, events and concepts that might have been familiar in the late 1940s but are today more obscure.

Prepared byØtheØTask Committee of the Urban Water Resources Research Council of ASCE. Copublished by ASCE and the Water Environment Federation. Design and Construction of Urban Stormwater Management Systems presents a comprehensive examination of the issues involved in engineering urban stormwater systems. This Manual?which updates relevant portions of Design and Construction of Sanitary and Storm Sewers, MOP 37?reflects the many changes taking place in the field, such as the use of microcomputers and the need to control the quality of runoff as well as the quantity. Chapters are prepared by authors with experience and expertise in the particular subject area. The Manual aids the practicing engineer by presenting a brief summary of currently accepted procedures relating to the following areas: financial services; regulations;Ø surveys and investigations;Ø design concepts and master planning;Ø hydrology and water quality;Ø storm drainage hydraulics; andØ computer modeling.
