Book Description
The behaviour of gold in sedimentary, magmatic and postmagmatic processes are studied and 40 gold-bearing minerals including ten which were recently discovered are described. The results are presented of new experimental studies on phase relations in gold-sulphide systems. The solubility & form of gold migration in high-temperature chloride, sulphide and arsenic solutions are determined. Based on the new data, the genesis of gold deposits is studied and a geochemical classification proposed. This book is designed for specialists in the field of gold chemistry, geochemistry and mineralogy and for field geologists surveying and prospecting for gold.

Book Description
What the Book Is About This book is about the problem of organizational learning, that is the analysis of organizations conceived as learning systems. In order to survive in a period of a rapid change, organizations must innovate and than to develop and exploit their abilities to learn. The most innovative organizations are those that can respond with great efficiency to internal and external changes. They respond to and generate technological change by acting as effective learning systems. They maximize the learning potential of ongoing and "normal" work activities. The organizational structure and the technology allow members to learn while the organizations itself learns from its members. So organizations reach high levels of innovation when structured to take advantage of the social, distributed, participative, situated processes of learning developed by its members in interaction with the technological environment. Organizations should consider learning as an explicit "productive" objective. They must create integrated learning mechanisms, that encompass technological tools, reward and incentive systems, human resource practices, belief systems, access to information, communication and mobility patterns, performance appraisal systems, organizational practices and structures. The design of efficient learning organizations requires cognitive, technological and social analyses. All the computer-based technologies (e. g. office automation, communication and group decision support) not only those devoted to and used in training activities, have to be considered as tools for organizational learning and innovation.

Book Description
One Nation Under Gold examines the countervailing forces that have long since divided America—whether gold should be a repository of hope, or a damaging delusion that has long since derailed the rational investor. Worshipped by Tea Party politicians but loathed by sane economists, gold has historically influenced American monetary policy and has exerted an often outsized influence on the national psyche for centuries. Now, acclaimed business writer James Ledbetter explores the tumultuous history and larger-than-life personalities—from George Washington to Richard Nixon—behind America’s volatile relationship to this hallowed metal and investigates what this enduring obsession reveals about the American identity. Exhaustively researched and expertly woven, One Nation Under Gold begins with the nation’s founding in the 1770s, when the new republic erupted with bitter debates over the implementation of paper currency in lieu of metal coins. Concerned that the colonies’ thirteen separate currencies would only lead to confusion and chaos, some Founding Fathers believed that a national currency would not only unify the fledgling nation but provide a perfect solution for a country that was believed to be lacking in natural silver and gold resources. Animating the "Wild West" economy of the nineteenth century with searing insights, Ledbetter brings to vivid life the actions of Whig president Andrew Jackson, one of gold’s most passionate advocates, whose vehement protest against a standardized national currency would precipitate the nation’s first feverish gold rush. Even after the establishment of a national paper currency, the virulent political divisions continued, reaching unprecedented heights at the Democratic National Convention in 1896, when presidential aspirant William Jennings Bryan delivered the legendary "Cross of Gold" speech that electrified an entire convention floor, stoking the fears of his agrarian supporters. While Bryan never amassed a wide-enough constituency to propel his cause into the White House, America’s stubborn attachment to gold persisted, wreaking so much havoc that FDR, in order to help rescue the moribund Depression economy, ordered a ban on private ownership of gold in 1933. In fact, so entrenched was the belief that gold should uphold the almighty dollar, it was not until 1973 that Richard Nixon ordered that the dollar be delinked from any relation to gold—completely overhauling international economic policy and cementing the dollar’s global significance. More intriguing is the fact that America’s exuberant fascination with gold has continued long after Nixon’s historic decree, as in the profusion of late-night television ads that appeal to goldbug speculators that proliferate even into the present. One Nation Under Gold reveals as much about American economic history as it does about the sectional divisions that continue to cleave our nation, ultimately becoming a unique history about economic irrationality and its influence on the American psyche.

Book Description
The aim of this book is to present recent achievements of in rare earth elements geology and mineralogy studies in China. The authors systematically describe all rare earth minerals and rare earth ore deposits discovered in China and their geological features. These rare earth minerals include huanghoite and baotite from China, as well as rare earth minerals from other parts of the world and new species and varieties discovered in China. For each mineral a systematic description of classification is given, such as chemical composition, crystallography and crystal structure, physical properties, X-ray powder data.
