From 1933 onward, Nazi Germany undertook massive and unprecedented industrial integration, submitting an entire economic sector to direct state oversight. This innovative study explores how German professionals navigated this complex landscape through the divergent careers of business managers in two of the era's most important trade organizations. While Jakob Reichert of the iron and steel industry unexpectedly resisted state control and was eventually driven to suicide, Karl Lange of the machine builders' association achieved security for himself and his industry by submitting to the Nazi regime. Both men's stories illuminate the options available to industrialists under the Third Reich, as well as the real priorities set by the industries they served.

Rare Earth Frontiers is a work of human geography that serves to demystify the powerful elements that make possible the miniaturization of electronics, green energy and medical technologies, and essential telecommunications and defense systems. Julie Michelle Klinger draws attention to the fact that the rare earths we rely on most are as common as copper or lead, and this means the implications of their extraction are global. Klinger excavates the rich historical origins and ongoing ramifications of the quest to mine rare earths in ever more impossible places. Klinger writes about the devastating damage to lives and the environment caused by the exploitation of rare earths. She demonstrates in human terms how scarcity myths have been conscripted into diverse geopolitical campaigns that use rare earth mining as a pretext to capture spaces that have historically fallen beyond the grasp of centralized power. These include legally and logistically forbidding locations in the Amazon, Greenland, and Afghanistan, and on the Moon. Drawing on ethnographic, archival, and interview data gathered in local languages and offering possible solutions to the problems it documents, this book examines the production of the rare earth frontier as a place, a concept, and a zone of contestation, sacrifice, and transformation.

This book explores substantial and methodological issues in the early modern history of mining for monetary metals and monies of Japan, China, and Europe. The largest group in the thirteen articles presents empirical research on mining, metallurgy, and metals trade in the context of global trade systems. Another group focuses on the effects of money in government and everyday life. Several articles investigate scroll paintings and material remains as sources for the history of technology, or apply Geographic Information Systems to the analysis of spatial dimensions of mining areas.

Increased understanding of the interactions between endophytic fungi and plants has led to the discovery of a new generation of chemical compounds and processes between endophytic fungi and plants. Due to the long-term co-evolution between fungal endophytes and host plants, endophytes have evolved special biotransformation abilities, which can have critical consequences on plant metabolic processes and their composition. Biotransformation or bioconversion can impact the synthesis and decomposition of hormones, sugars, amino acids, vitamins, lipids, proteins, and various secondary metabolites, including flavonoids, polysaccharides, and terpenes. Endophytic fungi produce enzymes and various bioactive secondary metabolites with industrial value and can degrade or sequester inorganic and organic small molecules and macromolecules (e.g., toxins, pollutants, heavy metals). These fungi also have the ability to cause highly selective catalytic conversion of high-value compounds in an environmentally friendly manner, which can be important for the production/innovation of bioactive molecules, food and nutrition, agriculture, and environment. This work mainly summarized recent research progress in this field, providing a reference for further research and application of fungal endophytes.Key points•The industrial value of degradation of endophytes was summarized.• The commercial value for the pharmaceutical industry is reviewed.

In this fascinating deep dive into the evolution of monetary systems around the globe, Nik Bhatia takes us into the origins of how money has evolved to function in a \"layered\" manner. Using gold as an example of this term, he traces the layers of this ancient currency from raw mined material, to gold coins, and finally to bank-issued gold certificates. In a groundbreaking manner, Bhatia offers a similar paradigm for the evolution of digital currencies. Bhatia's analysis begins in Renaissance Florence with the gold Florin coin and a burgeoning banking culture, continues with the evolution of central banking, and concludes with a vision for the future of our international monetary system. As central banks around the world prepare to launch their own crypto-competitors, Bhatia illustrates how the invention of Bitcoin created a seismic shift in money and merged the monetary and cryptography sciences. His unique analysis of \"layered money\" illuminates money markets for the general reader and shows how Bitcoin is becoming a trusted global currency. Readers will come away with an understanding of the mechanics of our financial system, why the dollar is deeply entrenched despite its state of disrepair, and how Central Bank Digital Currencies (CBDCs) and cryptocurrencies will interact in our new monetary future.

The availability of reliable commercial information is considered a key feature of inter-regional trade if the Roman economy was highly integrated. However, the extent to which archaeological and historical sources of inter-regional trade reflect the degree of economic integration is still not fully understood, a question which lies at the heart of current debates in Roman Studies. Ceramic tableware offers one of the only comparable and quantifiable sources of information for Roman inter-regional trade over centuries-long time periods. The distribution patterns and stylistic features of tablewares from the East Mediterranean dated between 200 BC and AD 300 suggest a competitive market where buying decisions might have been influenced by access to reliable commercial information. We contribute to this debate by representing three competing hypotheses in an agent-based model: success-biased social learning of tableware buying strategies (requiring access to reliable commercial information from all traders), unbiased social learning (requiring limited access), and independent learning (requiring no access). We use approximate Bayesian computation (ABC) to evaluate which hypothesis best describes archaeologically observed tableware distribution patterns. Our results revealed success-bias is not a viable theory and we demonstrate instead that local innovation (independent learning) is a plausible driving factor in inter-regional tableware trade. We also suggest that tableware distribution should instead be explored as a small component of long-distance trade cargoes dominated by foodstuffs, metals, and building materials.

Archaeologists use differences in metals from burial contexts to identify variation in social inequalities during the European Bronze Age. Many have argued that these social inequalities depended on access to, and control of, trade routes. In this paper, I model critical gateways in the Tisza river-a river system in the Carpathian Basin that might have enabled privileged access to metal in some areas but not others. I then evaluate the concentration of metal on different topological nodes of the river network in an attempt to understand what best explains the distribution of metals across this landscape. I do this by describing Bronze Age metal consumption and display in cemeteries from four micro-regions of the Tisza, and compare them with network 'betweenness centrality' values for locations along the river. I find support for the argument that favourably located river nodes had better access to metal in the earlier part of the Bronze Age.

01 02 From the late 1800s, African workers migrated to the mineral-rich hinterland areas of Guyana, mined gold, diamonds, and bauxite; diversified the country's economy; and contributed to national development. Utilizing real estate, financial, and death records, as well as oral accounts of the labor migrants along with colonial officials and mining companies' information stored in National Archives in Guyana, Great Britain, and the U.S. Library of Congress, the study situates miners into the historical structure of the country's economic development. It analyzes the workers attraction to mining from agriculture, their concepts of \"order and progress,\" and how they shaped their lives in positive ways rather than becoming mere victims of colonialism. In this contentious plantation society plagued by adversarial relations between the economic elites and the laboring class, in addition to producing the strategically important bauxite for the aviation era of World Wars I & II, for almost a century the workers braved the ecologically hostile and sometimes deadly environments of the gold and diamond fields in the quest for El Dorado in Guyana. 02 02 From the late 1800s, African workers migrated to the mineral-rich hinterland areas of Guyana, mined gold, diamonds, and bauxite; diversified the country's economy; and contributed to national development.
