COLLEGE-TO-WORK MIGRATION OF TECHNOLOGY GRADUATES AND HOLDERS OF DOCTORATES WITHIN THE UNITED STATES

ABSTRACT.  This study estimates a series of random parameter logit models of the college-to-work migration decisions of technology graduates and holders of doctorates within the United States. We employ detailed information on the migration-relevant characteristics of individuals, as well as on their actual origins and destinations at the metropolitan scale. In addition to its obvious implications for "brain drain" policies in U.S. metropolitan areas, the study demonstrates the richness of the random parameters technique for behavioral-geographic analysis. We find that science and technology graduates migrate to better educated places, other things equal; that PhD graduates pay greater attention to amenity characteristics than other degree holders; and that foreign students from some immigrant groups migrate to places where those groups are concentrated.     

The dynamics of family farming in North Huron County, Ontario. Part II. Farm–community interactions

In Canada and elsewhere, there is a growing belief that farming and rural communities have become effectively disconnected from one another. While attention to recent media reporting suggests that incidences of conflict are now as common as examples of support and collaboration, it is suggested that many examples of complementarity remain. These evolving relationships may, however, be linked to the nature of specific farm development trajectories. Such possibilities warrant empirical examination, with attention to known diversity in the family farm sector. This paper reports on an empirical investigation of farm and community linkages in North Huron County, Ontario. The paper builds upon a recent investigation of change in family farming in this region and seeks to document the ways in which local farmers continue to look to their rural communities for support of various kinds. Data are drawn from a survey of farmers in Ashfield and Colborne Townships in 1999. The research explores community linkages around three dominant themes: participation in organisations, purchasing and perceptions and experiences of community support for farming. The findings indicate the persistence of strong linkages between farms and local communities in the study region but point to a potential tendency for disconnection between farms pursuing aggressive expansion and local community organisations and businesses. There is some evidence that jobs and a variety of farm household considerations may form key linkage points between the two sectors, with the importance of these mediated by farm business trajectories and the family life course.     

Oldowan behavior and raw material transport: perspectives from the Kanjera Formation

The archaeological record of Oldowan hominins represents a diverse behavioral system. It has been suggested that exploitation of lithic resources by Oldowan hominins was simplistic and represented mostly use of local sources of stone. Here we investigate the raw material selection and transport behaviors of Oldowan hominins reflected in the stone artifact assemblages from the Kanjera South Formation, South Rachuonyo District, Kenya. Using geochemical methods (ED-XRF) artifacts are linked to primary and secondary source outcrops throughout southwestern Kenya. These data show that hominins selected raw materials for transport at frequencies that are significantly different from their availability on ancient landscapes. Furthermore, a substantial proportion of the assemblage represents transport over relatively long distances (>10 km). Our study further suggests that in the early stages of stone tool use hominins used a wide variety of raw materials and selected these materials at some distance from their eventual discard locations. Early hominin behavior may have incorporated an understanding of raw material source distributions across a more extensive landscape than has been previously documented. This supports the growing perspective that Oldowan technology represents a more complex behavioral pattern than is usually associated with the beginnings of hominin tool use.     

The Ethnoarchaeology of Reptile Remains at a Lake Turkana Occupation Site, Kenya

The role of reptiles in hominid hunter–gatherer subsistence in Pleistocene Africa has been largely overlooked. This study examines the reptile component of a modern lake shore camp (site 20) assemblage of low archaeological visibility. Site 20, located on the eastern shore of Lake Turkana, has been observed from its creation to burial. The site is an ideal modern analogue for the interpretation of African prehistoric archaeological sites. Patterns of element loss, and patterns of bone modifications, namely burn, cut and slice marks, are examined. From this baseline data, three conclusions are drawn regarding the interpretability of reptile remains found at archaeological lakeside sites: (1) the MNI of crocodile remains at a site is likely to be similar to the original number of individuals which contributed to the deposited assemblage; (2) the MNI estimates of the turtle component will be much less than the original number of individuals in the deposited assemblage; and (3) patterns of bone modifications can be related to hominid food procurement and processing activities.     

PRACTICING THE CULTURAL GREEN ECONOMY: WHERE NOW FOR ENVIRONMENTAL SOCIAL SCIENCE?

Debates concerning the development of the green economy necessarily focus on “upstream” issues that underpin the re‐structuring of national and regional economies through the lenses of financial, institutional and regulatory change. However, the growing interest in the cultural green economy requires a re‐scaling of debates surrounding the links that occur in complex socio‐technical systems, notably between individual consumers, social units and the architectures of the developing green economy. This necessitates a research and policy agenda that is attentive to both the complexities of such interactions (between structures, processes and practices) and the imperative to foster change in practices within wider society. This article explores the ways in which environmental social scientists have examined and evidenced these issues, arguing that two major barriers still exist for creating adequate understandings and opportunities for change. First, the overt focus on the individual consumer as a unit of measurement and political attention has stifled debate concerning the ways in which environmentally related social practices have developed in association with wider economic contexts. In this way, environmental social scientists have often failed to make the connections between individuals, practices and the economic system. Second, in adopting a largely individualistic perspective, environmental social scientists have tended to focus their attention on incrementalist and narrowly defined views of what ecological citizenship might look like and constitute in the green economy. The article therefore argues that environmental social scientists need to constructively engage in a new inter‐disciplinary dialogue about the role, purpose and ethics of citizen participation in developing and sustaining the green economy in an age of climate change and potential resource scarcity.
