This book provides a review of current research in fake news and presents six new empirical research studies examining its impact. Fake news has garnered immense public attention following the 2016 Brexit referendum, three US elections, the 2019 Indian lynchings, and so on. Fake news undermines public life across the globe, especially in countries where journalistic practices and institutions are weak. Some fake news is created to spread ideological messages or to create mischief, whereas other fake news is created for profit. Research shows that fake news spreads farther, faster, and more broadly than true news and has had major societal impacts. All signs indicate that it will get worse as political activists, scammers, alternative news media, and hostile governments become more sophisticated in their production and targeting of fake news. This book features leading scholars who provide a review of the current research and presents six new empirical research studies examining its impact. Some of this research shows how inventions designed to reduce fake news can actually have the opposite effect, and instead act to increase the spread of fake news. Other research takes a longer-term perspective, by measuring or inserting emotions into headlines, allowing us to examine some of the roots of fake news behaviors for future study. This shows how challenging the fake news phenomenon is to solve. Fake News on the Internet will be a key resource for academics, researchers, and advanced students of Media Studies, Research Methods, Information Systems, Communication Studies, Management, Cultural Studies and Sociology. The chapters included in this book were originally published as a special issue of Journal of Management Information Systems.

Tillage agriculture has led to widespread soil and ecosystem degradation globally. This is especially so in Africa where traditional and modern tillage-based agricultural practices have become unsustainable due to severe disturbance and exploitation of natural resources, with negative impacts on the environment and rural livelihoods. In addition, agriculture in Africa today faces major challenges including increased costs of production and energy, the effects of climate change, and the lack of an effective paradigm for sustainable intensification, especially for small- and medium-size holdings. Africa is facing a serious challenge to food security and as a continent has not advanced towards eradicating hunger. In addition, the population is still growing much faster than on most other continents. This pressure has led to the emergence of no-till conservation agriculture as a serious alternative sustainable agriculture paradigm. In Africa, in recent years, conservation agriculture techniques and methods have spread to many countries, as greater development, education and research effort are directed towards its extension and uptake. This book is aimed at agricultural researchers and scientists, educationalists, and agricultural service providers, institutional leaders and policy makers working in the fields of sustainable agriculture and international development, and also at agroecologists, conservation scientists, and those working on ecosystem services. This book: * Focuses on research and development initiatives in Africa aimed at building resilient farming systems based on conservation agriculture principles and practices. * Summarises the status of conservation agriculture in Africa today and prospects for its future development in Africa as a basis for sustainable agriculture intensification. * Describes case studies showing the performance of conservation agriculture in Africa.

Combining the intimacy of memoir and the precision of history, the story of psychologist Nicolae Margineanu's imprisonment and survival conveys in striking detail the corrosive impact of Communist rule in Romania. Nicolae Margineanu's journey started in 1905 in the village of Obreja in Transylvania and ended in 1980 in Cluj-Napoca, Romania. He began his life under Austro-Hungarian rule, was witness to the 1918 Union, lived under three kings(Ferdinand, Carol II, and Mihai), and survived all of Romania's dictatorships, from absolute monarchy to the Legionnaires' rebellion, the Antonescian dictatorship, and finally the years under Communist rule. Margineanu studied psychology at the University of Cluj and attended postgraduate courses in Leipzig, Berlin, Hamburg, Paris, and London. He was awarded a Rockefeller Foundation fellowship that enabled him to do research for two years in the United States, at Harvard, Yale, Columbia, the University of Chicago, and Duke. He returned to Romania and became chair of the psychology department at the University of Cluj. In 1948, Margineanu was arrested on a charge of "high treason," based on his alleged membership in a resistance movement against Communist rule. He was sentenced to twenty-five years' imprisonment, of which he served sixteen, passing through the jails at Malmaison, Jilava, Pitesti,Aiud, and Gherla. This book, his autobiography, is a shocking testimony to the fate of the intellectual elite of Romania during the Communist dictatorship. It is a unique and invaluable addition to the literature in English on the experience of political prisoners, not only in Communist Romania but in authoritarian states in general. Nicolae Margineanu (1905-1980) was a Romanian psychologist and writer who was a political prisoner during theperiod of Communist rule. Dennis Deletant is the Visiting Ratiu Professor of Romanian Studies at Georgetown University. Calin Cotoiu is a translator based in Bucharest, Romania.

This new edition provides an update on the considerable amount of evidence on tree-crop interactions which has accumulated during the last two decades, especially on the more complex multi-strata agroforestry systems, which are typical of the humid tropics. In addition three new chapters have been added to describe the new advances in the relationship between climate change adaptation, rural development and how trees and agroforestry will contribute to a likely reduction in vulnerability to climate change in developing countries
