Race relations in New Orleans have often been narrowed to Black and white, especially pre-Katrina. According to the 2000 census, the city was about 67% African American, 27% white, 2% Asian, and 3% “Hispanic.” In a city with a deep history of racial tensions between Black and white, other people of color—and especially recent immigrants—often went unmentioned in discussions of city demographics. The city’s world famous culture—whether in the traditions of Mardi Gras Indians and secondline parades, or in music like jazz and bounce—is also famously rooted in specifically African cultures. Even in media coverage of the city post-Katrina, the story of immigrant experiences has remained mostly invisible. When these stories have been told, they have often fit into the old stereotypes of “model minorities” (as in the case of the Vietnamese recovery) or of low-wage workers stealing jobs (as in the case of news reports on the city’s new Latino population). However, the stories of these other New Orleanians offer an important lens through which to view the overall struggle over the city’s recovery. And the work of grassroots activists from these communities, who strived to not only work for justice for their friends and neighbors, but also to build broad multi-racial alliances, provides an inspiring example for people in other cities who are waging similar fights.  相似文献

Recent academic research suggests that the effects of inward foreign direct investment for productivity and employment may vary across foreign investors with different characteristics. Using a newly created dataset that integrates micro-level information from The Netherlands Foreign Investment Agency and Statistics Netherlands, this paper explores the role of several of these characteristics, including e.g. the country of origin, activities and tasks, age and strategic role of foreign affiliates in The Netherlands in the 2000–2007 period. Our analysis shows that important employment and productivity differences exist for nearly all these dimensions.  相似文献

December 1, 1996 a new law was implemented in Portugal to gradually reduce the standard workweek from 44 to 40 h. We study how this mandatory reduction affected employment through job creation and job destruction. There was considerable regional, sectoral and firm-size variation in the share of workers who were affected by the working hours reduction. We exploit this variation to assess the impact of the workweek reduction. We find evidence that the working hours reduction had a positive effect on employment through a fall in job destruction.  相似文献

Overreaction to Fearsome Risks   总被引:1,自引:0,他引:1  
When risks threaten, cognitive mechanisms bias people toward action or inaction. Fearsome risks are highly available. The availability bias tells us that this leads people to overestimate their frequency. Therefore, they also overreact to curtail the likelihood or consequences of such risks. More generally, fear can paralyze efforts to think clearly about risks. We draw on a range of environmental risks to show the following: (1) Fear leads us to neglect probability of occurrence; (2) As fearsome environmental risks are usually imposed by others (as externalities), indignation stirs excess reaction; (3) We often misperceive or miscalculate such risks. Two experiments demonstrate probability neglect when fearsome risks arise: (a) willingness-to-pay to eliminate the cancer risk from arsenic in water (described in vivid terms) did not vary despite a 10-fold variation in risk; (b) the willingness-to-accept price for a painful but non dangerous electric shock did not vary between a 1 and 100% chance. Possible explanations relate to the role of the amygdala in impairing cognitive brain function. Government and the law, both made by mortals and both responding to public pressures, similarly neglect probabilities for fearsome risks. Examples relating to shark attacks, Love Canal, alar and terrorism are discussed.  相似文献
