Available in PDF, EPUB and Kindle. Book excerpt: Before the Vichy regime, there was ostensibly only one France and one form of colonialism for French West Africa (FWA). World War II and the division of France into two ideological camps, each asking for legitimacy from the colonized, opened for Africans numerous unprecedented options. French Colonialism Unmasked analyzes three dramatic years in the history of FWA, from 1940 to 1943, in which the Vichy regime tried to impose the ideology of the National Revolution in the region. Ruth Ginio shows how this was a watershed period in the history of the region by providing an in-depth examination of the Vichy colonial visions and practices in fwa. She describes the intriguing encounters between the colonial regime and African society along with the responses of different sectors in the African population to the Vichy policy. Although French Colonialism Unmasked focuses on one region within the French Empire, it has relevance to French colonial history in general by providing one of the missing pieces in research on Vichy colonialism. Ruth Ginio is a research fellow at the Harry S. Truman Research Institute for the Advancement of Peace in the Hebrew University of Jerusalem. She is the author of articles in International Journal of African Historical Studies, Revue d'histoire moderne et contemporaine, Cahiers d'etudes africaines, and several other journals.

Available in PDF, EPUB and Kindle. Book excerpt: In an effort to restore its world-power status after the humiliation of defeat and occupation, France was eager to maintain its overseas empire at the end of the Second World War. Yet just fifteen years later France had decolonized, and by 1960 only a few small island territories remained under French control.The process of decolonization in Indochina and Algeria has been widely studied, but much less has been written about decolonization in France's largest colony, French West Africa. Here, the French approach was regarded as exemplary -- that is, a smooth transition successfully managed by well intentioned French politicians and enlightened African leaders. Overturning this received wisdom, Chafer argues that the rapid unfurling of events after the Second World War was a complex , piecemeal and unpredictable process, resulting in a 'successful decolonization' that was achieved largely by accident. At independence, the winners assumed the reins of political power, while the losers were often repressed, imprisoned or silenced.This important book challenges the traditional dichotomy between 'imperial' and 'colonial' history and will be of interest to students of imperial and French history, politics and international relations, development and post-colonial studies.

Available in PDF, EPUB and Kindle. Book excerpt: Over the 20th century, Morocco has become one of the world’s major emigration countries. But since 2000, growing immigration and settlement of migrants from sub-Saharan Africa, the Middle East, and Europe confronts Morocco with an entirely new set of social, cultural, political and legal issues. This book explores how continued emigration and increasing immigration is transforming contemporary Moroccan society, with a particular emphasis on the way the Moroccan state is dealing with shifting migratory realities. The authors of this collective volume embark on a dialogue between theory and empirical research, showcasing how contemporary migration theories help understanding recent trends in Moroccan migration, and, vice-versa, how the specific Moroccan case enriches migration theory. This perspective helps to overcome the still predominant Western-centric research view that artificially divide the world into ‘receiving’ and ‘sending’ countries and largely disregards the dynamics of and experiences with migration in countries in the Global South. This book was previously published as a special issue of The Journal of North African Studies.

Available in PDF, EPUB and Kindle. Book excerpt: Austin, Texas, is renowned as a high-tech, fast-growing city for the young and creative, a cool place to live, and the scene of internationally famous events such as SXSW and Formula 1. But as in many American cities, poverty and penury are booming along with wealth and material abundance in contemporary Austin. Rich and poor residents lead increasingly separate lives as growing socioeconomic inequality underscores residential, class, racial, and ethnic segregation. In Invisible in Austin, the award-winning sociologist Javier Auyero and a team of graduate students explore the lives of those working at the bottom of the social order: house cleaners, office-machine repairers, cab drivers, restaurant cooks and dishwashers, exotic dancers, musicians, and roofers, among others. Recounting their subjects’ life stories with empathy and sociological insight, the authors show us how these lives are driven by a complex mix of individual and social forces. These poignant stories compel us to see how poor people who provide indispensable services for all city residents struggle daily with substandard housing, inadequate public services and schools, and environmental risks. Timely and essential reading, Invisible in Austin makes visible the growing gap between rich and poor that is reconfiguring the cityscape of one of America’s most dynamic places, as low-wage workers are forced to the social and symbolic margins.

This book was released on 2017-04-07 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: The condition of precariousness not only provides insights into a segment of the world of work or of a particular subject group, but is also a standpoint for an overview of the condition of the social on a global scale. Because precariousness is multidimensional and polysemantic, it traverses contemporary society and multiple contexts, from industrial to class, gender, family relations as well as political participation, citizenship and migration. This book maps the differences and similarities in the ways precariousness and insecurity in employment and beyond unfold and are subjectively experienced in regions and sectors that are confronted with different labour histories, legislations and economic priorities. Establishing a constructive dialogue amongst different global regions and across disciplines, the chapters explore the shift from precariousness to precariat and collective subjects as it is being articulated in the current global crisis. This edited collection aims to continue a process of mapping experiences by means of ethnographies, fieldwork, interviews, content analysis, where the precarious define their condition and explain how they try to withdraw from, cope with or embrace it. This is valuable reading for students and academics interested in geography, sociology, economics and labour studies.

Available in PDF, EPUB and Kindle. Book excerpt: The economic boom of the 1990s veiled a grim reality: in addition to the growing gap between rich and poor, the gap between good and bad quality jobs was also expanding. The postwar prosperity of the mid-twentieth century had enabled millions of American workers to join the middle class, but as author Arne L. Kalleberg shows, by the 1970s this upward movement had slowed, in part due to the steady disappearance of secure, well-paying industrial jobs. Ever since, precarious employment has been on the rise—paying low wages, offering few benefits, and with virtually no long-term security. Today, the polarization between workers with higher skill levels and those with low skills and low wages is more entrenched than ever. Good Jobs, Bad Jobs traces this trend to large-scale transformations in the American labor market and the changing demographics of low-wage workers. Kalleberg draws on nearly four decades of survey data, as well as his own research, to evaluate trends in U.S. job quality and suggest ways to improve American labor market practices and social policies. Good Jobs, Bad Jobs provides an insightful analysis of how and why precarious employment is gaining ground in the labor market and the role these developments have played in the decline of the middle class. Kalleberg shows that by the 1970s, government deregulation, global competition, and the rise of the service sector gained traction, while institutional protections for workers—such as unions and minimum-wage legislation—weakened. Together, these forces marked the end of postwar security for American workers. The composition of the labor force also changed significantly; the number of dual-earner families increased, as did the share of the workforce comprised of women, non-white, and immigrant workers. Of these groups, blacks, Latinos, and immigrants remain concentrated in the most precarious and low-quality jobs, with educational attainment being the leading indicator of who will earn the highest wages and experience the most job security and highest levels of autonomy and control over their jobs and schedules. Kalleberg demonstrates, however, that building a better safety net—increasing government responsibility for worker health care and retirement, as well as strengthening unions—can go a long way toward redressing the effects of today’s volatile labor market. There is every reason to expect that the growth of precarious jobs—which already make up a significant share of the American job market—will continue. Good Jobs, Bad Jobs deftly shows that the decline in U.S. job quality is not the result of fluctuations in the business cycle, but rather the result of economic restructuring and the disappearance of institutional protections for workers. Only government, employers and labor working together on long-term strategies—including an expanded safety net, strengthened legal protections, and better training opportunities—can help reverse this trend.
