They exhibit uniquely low defect formation energies, leading to unusual doping and phase behavior and to extremely benign grain boundaries. This book collects articles on a number of those basic material properties of wide-gap chalcopyrites, comparing them to their low-gap cousins. They explore the doping of the materials, the electronic structure and the transport through interfaces and grain boundaries, the formation of the electric field in a solar cell, the mechanisms and suppression of recombination, the role of inhomogeneities, and the technological role of wide-gap chalcopyrites.  Free Download Jinghao Zhou, "Why Is the China Model Losing Its Power?" English | ISBN: 9811216274 | 2020 | 250 pages | EPUB | 6 MB History has proved that communism failed at many levels during the first global competition between the capitalist and socialist camps during the Cold War. As a result, the socialist camp was dissolved. China is one of the few communist countries to survive in the twenty-first century. The Chinese economy was on the verge of collapse in the 1970s but began to take off in the early 1980s, guided by the China model. China became the world's second largest economy in 2010 and has quickly expanded its enormous global market and political influence. The second global competition between the capitalist countries and China has started. The second global competition is in fact between the China model and the Washington Consensus. Will Western hegemonies end as the result of the second global competition? Will China be able to rewrite the international rules? Will the Chinese communist political system collapse during the competition? What should the West do to the China model? This book will explore the implications of the China model in the context of the second global competition and argues that the downturn of the China model and China's global expansion are the two sides of the same coin. The China model is losing its power but not broken. China would be able to become even stronger, if it could reshape the philosophical foundation of the China model. The future of Western hegemony will depend on how the West understands the China model and deals with it. This book addresses these aspects and more.  Free Download When Women Come First: Gender and Class in Transnational Migration By Sheba George 2005 | 296 Pages | ISBN: 0520938356 | PDF | 1 MB With a subtle yet penetrating understanding of the intricate interplay of gender, race, and class, Sheba George examines an unusual immigration pattern to analyze what happens when women who migrate before men become the breadwinners in the family. Focusing on a group of female nurses who moved from India to the United States before their husbands, she shows that this story of economic mobility and professional achievement conceals underlying conditions of upheaval not only in the families and immigrant community but also in the sending community in India. This richly textured and impeccably researched study deftly illustrates the complex reconfigurations of gender and class relations concealed behind a quintessential American success story. When Women Come First explains how men who lost social status in the immigration process attempted to reclaim ground by creating new roles for themselves in their church. Ironically, they were stigmatized by other upper class immigrants as men who needed to "play in the church" because the "nurses were the bosses" in their homes. At the same time, the nurses were stigmatized as lower class, sexually loose women with too much independence. George's absorbing story of how these women and men negotiate this complicated network provides a groundbreaking perspective on the shifting interactions of two nations and two cultures.  Free Download Malek Abisaab, "What the War Left Behind: Women's Stories of Resistance and Struggle in Lebanon" English | ISBN: 081563837X | 2024 | 288 pages | PDF | 6 MB Conspicuously missing from narratives of the Lebanese Civil War are the stories of women who took part in daily social activism and political organizing during the tumultuous conflict. What the War Left Behind documents their stories, with eight women directly sharing their experiences of action and survival through the hardship of war. What the War Left Behind brings together oral histories of women from a range of political affiliations, socioeconomic classes, and religious identities. These histories present an alternative image of women during war, highlighting the actions of those who sought to make life better for themselves and their neighbors during conflict. By centering women's voices in the war, Abisaab and Hartman present a new perspective on an oft-discussed historical era, demonstrating the power of resistance during difficult times. These translated texts showcase the active roles women take during wartime and how women's political efforts are an essential part of Lebanese history.  Free Download What Price Better Health?: Hazards of the Research Imperative By Daniel Callahan 2003 | 341 Pages | ISBN: 0520939239 | PDF | 1 MB The idea that we have an unlimited moral imperative to pursue medical research is deeply rooted in American society and medicine. In this provocative work, Daniel Callahan exposes the ways in which such a seemingly high and humane ideal can be corrupted and distorted into a harmful practice. Medical research, with its power to attract money and political support, and its promise of cures for a wide range of medical burdens, has good and bad sides-which are often indistinguishable. In What Price Better Health?, Callahan teases out the distinctions and differences, revealing the difficulties that result when the research imperative is suffused with excessive zeal, adulterated by the profit motive, or used to justify cutting moral corners. Exploring the National Institutes of Health's annual budget, the inflated estimates of health care cost savings that result from research, the high prices charged by drug companies, the use and misuse of human subjects for medical testing, and the controversies surrounding human cloning and stem cell research, Callahan clarifies the fine line between doing good and doing harm in the name of medical progress. His work shows that medical research must be understood in light of other social and economic needs and how even the research imperative, dedicated to the highest human good, has its limits.  Free Download What Is the Token Economy? by Shermin Voshmgir English | 2021 | ISBN: 9781492072973 | EPUB | 1.37 Mb Blockchain-based protocols like Bitcoin and Ethereum have made sending digital values in the form of tokens as cheap and easy as sending an email. But while cryptographic tokens (sometimes called "cryptocurrencies") may be as important to the next-generation internet as the World Wide Web was to Web 1.0, people aren't yet sure how to best design tokens or even what to do with them.

Parker, "Webster's Spanish to English Crossword Puzzles: Level 6" English | 2006 | pages: 118 | ISBN: 049725560X | PDF | 0,6 mb Even if you do not like crossword puzzles, you may end up loving these. Designed for mother-tongue or completely fluent speakers of Spanish wanting to improve their English skills, the puzzles may also be entertaining to English speakers. They are formatted so that each puzzle can be solved in 15 to 30 minutes. The vocabulary gradually becomes harder across puzzles thus increasing the challenge as you progress. Each book has 100 puzzles and each puzzle covers some 30 word pairs (equaling 3000 challenges!). These are truly pleasant, if not addictive, crossword puzzles for language learning. Learning a language is always difficult. To ease the pain, hints are provided in small script at the bottom of each page, though these are selected to prevent an engineered solution to the puzzle. Full solutions are provided in the back of the book. These two features (hints and verifiable solutions), force the reader to decipher a word's meaning and serves to improve vocabulary retention and understanding. One recent reviewer of this series noted "As a Peace Corps Volunteer ... this is definitely a fun way to keep up the language skills ... The series has a whole bunch of "rarely spoken" languages, widely unknown to us in the Western world." Another reviewer notes: "Good teacher as it has words listed below that are in puzzle so the clues are there if you need them." Public domain translations for Spanish contributed to Webster's Online Dictionary used in these puzzles may have originated from uncited volunteers, native speakers, professional translators, field linguists and academics (not by the editor of the puzzles). If you would like citation for any translations, make suggestions, note errors, or contribute in any other way, please email Philip M. Parker at INSEAD, who will update this series from time to time.
