Brazilian immigration to the United States is a relatively recent phenomenon that gained momentum in the 1980s in unprecedented numbers. Today an estimated 1.2 million Brazilians live in the United States. Brazilians (re)create transnational places and spaces through social, cultural, and economic practices, within the immigrant receiving communities of Marietta, Georgia, and Framingham, Massachusetts, in the United States. They also incorporate and add new elements to their livelihoods in the respective sending communities of Piracanjuba, in the state of Goiás, and Governador Valadares, in the state of Minas Gerais, in Brazil. How are these Portuguese-speaking Brazilian immigrants shaping and (re)creating new places and spaces? In what ways and spheres do transnational exchanges affect two places of destination in the United States and two places of origin in Brazil after migration occurs? Using multiple methods, which include in-depth interviews and participant observation, this paper addresses these questions by evaluating the changes incurred by migration. I use a framework perspective that is largely from outside the Latino/Hispanic context. Migration processes are just as much about those who leave Brazil for the United States as it is about those who return to Brazil (i.e. returnees) and what happens to those respective receiving and sending communities in both countries.  相似文献

A tension exists between government and the academy. State and federal agencies demand that colleges and universities demonstrate their accountability for public funds and to public policy initiatives. The campuses hold that such requirements have come to represent an inappropriate intrusion into institutional affairs and that they present a serious challenge to academic freedom. While a reduction and redirection of regulation may serve the colleges veil, a review of history indicates that the important developments in higher education have occurred during periods of government involvement. Perhaps, then, the real fear that should be felt on campus is the- recent trend of government disinterest in higher education.  相似文献

The use of close-range digital photogrammetry for field documentation has been steadily increasing in the past half decade in several parts of the world. However, this technology has not been widely utilized in archaeological contexts in the American Midwest. We explore the utility of close-range photogrammetry in this region with examples from the Guard site (12D29), a Fort Ancient village located in southeastern Indiana. This article outlines the methods utilized for production of georeferenced 3-D models of several units excavated during the 2016 field season. These models as well as plan and profile orthophotos derived from them act as important supplements to standard photographs and drawings made in the field and easily integrate with the site GIS. Overall, we found close-range digital photogrammetry to be very useful to better document excavation details, doing so for limited cost and time expenditure.  相似文献
