This article discusses the legal context in which health research of undocumented Mexicans takes place. Two lines of inquiry are brought together: the national debate on undocumented immigration and the maturing research on the health of Mexican Americans. Because of the politicized nature of immigration status, “immigration” is ignored as an explanatory variable. Several potential outcomes are examined, such as “ghost” programming and increased public health risks.  相似文献

The aim of this paper is to identify the determinants of the geographical mobility of skilled individuals, such as inventors, across European regions. Among a large number of variables, we focus on the role of social proximity between inventors’ communities. We use a control function approach to address the endogenous nature of networks, and zero‐inflated negative binomial models to accommodate our estimations to the count nature of the dependent variable and the high number of zeros it contains. Our results highlight the importance of physical proximity, job opportunities, social networks, as well as other relational variables in mediating this phenomenon.  相似文献

Recognizing that post-modernism (broadly defined) has had a significant impact upon contemporary geographical practice, this essay considers the claims of its proponents and seeks to weigh the implications of the postmodernist impulse for the subject as a whole. On balance, recent engagements with the ideas of a broad spectrum of important philosophers and critical theorists are seen to have broadened, enlivened, and in some respects enhanced human geography. The impress upon physical geography has been much less consequential. Yet many post-modernist claims must be met with circumspection. Embraced tout ensemble, they would seem to blinker understanding, limit practical engagement with the world, and imperil the foundations upon which important geographical work has been (and should continue to be) built. In human as well as physical geography, different scales of inquiry favour (even require) different modes of analysis, and a respectful understanding of different scholarly aims and means is essential if Geography is to remain robust well into the new millen nium. Étant donné que le postmodernisme (au sens large) a beaucoup influé sur les pratiques de la géographie contemporaine, cet essai étudie les affirmations de ses partisans et cherche àévaluer les implications du post-modernisme pour la discipline dans sa totalité. En fin de compte, l'utilisation des idées de toute une gamme de philosophes importants et de théoriciens du post-modernisme peut être perçue comme ayant élargi et à certains égards amélioré la géographie humaine. L'impact du postmodernisme sur la géographie physique a été beaucoup moins important. Et pourtant, on doit envisager avec beaucoup de prudence les prétentions des partisans du postmodernisme. Si l'on accepte toutes ces théories dans leur ensemble, on risque de mettre en cause notre compréhension du monde et de nuire aux fondements mêmes sur lesquels la recherche en géographie a été (et continuera àêtre) construite. En géographie humaine aussi bien qu'en géographie physique, l'échelle des recherches entreprises implique (et même nécessite) l'utilisation de différentes méthodes d'analyse. Une compréhension respectueuse des différents objectifs et méthodes des chercheurs en géographie est essentielle, si nous voulons que la géographie en tant que discipline maintienne sa vigueur au-delà du seuil du nouveau millénaire.  相似文献

Global social, political, and economic change during the past quarter-century has been profound, particularly in major areas with languages different from those usually employed by Canadian geographers. Surveys by the author suggest that senior Canadian geography graduate students, however, are inadequately prepared to assimilate primary world sources of information, including the relevant research literatures (except those published in this country's two official languages), and that few geography departments any longer require competence in more than one language at any level of study. Nevertheless, geographers and their students could benefit in many ways from foreign language expertise. Suggestions are made whereby geography departments could reinforce their existing rigorous training programs with foreign linguistic and area competence.  相似文献

This article discusses the impact of genomic history, a subdiscipline that emerged in the study of the ancient Mediterranean in the 2010s. In 2014, scientists first published a method for extracting genetic material, which they christened aDNA (ancient DNA), from ancient human remains in hot climates. After a decade of research, genomic history is now poised to transform our understanding of Mediterranean premodernity, centering migration and conflict as the key mechanisms for cultural change. Despite years of critique, aDNA researchers have failed to seriously examine the bioessentialist assumptions implicit in their work—a failure that has led many to deploy language that is strikingly evocative of pre-World War II racialism. Even worse, some genomic historians continue to make troubling overtures toward the ethnonationalist Right, which has been ascendant across Europe and North America since the 2010s. This article traces the intellectual genealogy of genomic history from World War II to the present, examines recent attempts to answer criticism from the humanities and social sciences, and suggests paths for responsible use of aDNA in historical and prehistorical scholarship.  相似文献

Casa Montero is a mining complex located outside Madrid (Spain), dated from the Early Neolithic (c. 5400–5000 cal bc ). An area of some 4 ha has been investigated and some 4000 shafts recorded, of which 324 have been excavated. The characterization of its raw flint materials and the establishment of its diagnostic features are indispensable in the reconstruction of the distribution of the mine's products beyond the immediate site. This work reports the geological study of the mine's Miocene flint layers and their petrological characterization. Archaeological samples from the mine's shafts were classified according to macroscopic features and petrological characteristics.  相似文献

By rejecting the old divide between prehistory and history, the group of scholars behind Deep History opens a new window on the problem of the unity and diversity of human experience over the very long run. Their use of kinship metaphors suggests not only a link between modern society and the deep past, but also perhaps a way to imagine the common legacy of the human species. But what emerges from Deep History is hardly a sunny story about the distant origins of social justice and ecological harmony. The other central metaphor of the book—the fractal—uncovers the slow prelude to the Anthropocene. Rather than seeing a sharp break in the Industrial Revolution from an “organic” to a fossil fuel‐burning economy, these scholars stress the history of environmental destruction that has accompanied human expansion. My critical reading presents an alternative understanding of deep history as an arena for a new politics of species. Here a cornucopian understanding of human adaptation clashes with a new pessimism about the climatic fragility of Neolithic civilization.  相似文献

Spatial language and constructs are deployed systematically in the writing of many contemporary feminists. Disempowerment is couched in negative spatial terms: as “displacement,” having space denied, or as a negative or non-space. Empowerment, on the other hand, is written as an appropriation of the spatial: creating new spaces, occupying existing spaces, or revalorizing negatively labeled spaces. Furthermore, the map emerges as a common trope in this writing. Rather than transparently communicating the totality of what exists, however, their maps become rhetorical guides to possible worlds. The spatial provides a textual tool with which many contemporary feminists contest existing power relations. Space is viewed as liberating, empowering, and political. Their use of the spatial contrasts with the apolitical (and, not inconsequentially, gendered) conceptualization of space in some postmodern writing. This divergent deployment of spatial textual devices in the writing of some contemporary feminists and that of some postmodernists opens up another window on the knotty nexus of feminist and postmodern thought in geography.  相似文献

This essay examines how and why historiography—defined to mean the study of the history of historical writing—first emerged as a legitimate subject of historical inquiry in the United States during the period from 1890 to the 1930s by focusing on the practice of historiography by three of the most influential American historiographers whose work spans this period: J. Franklin Jameson, John Spencer Bassett, and Harry Elmer Barnes. Whereas the development of historiography as a field of study signified a recognition that historians and historical writing are themselves products of the historical process, American historiographers in this period at the same time used historiography to further a scientific ideal of objectivity that was premised on the belief in the ability of historians to separate themselves from that process. Modern scholars (notably, Peter Novick) have attributed to scientific historians like Jameson and Bassett a simplistic and naive positivism; but the ability of these historiographers to recognize the subjective character of historical writing and yet affirm a belief in objectivity reveals that their understanding of historical truth was more complex than modern scholars have acknowledged. In turn, by questioning the belief that the historical profession was originally founded on a naïve faith in the ideal of objective truth, I demonstrate that New Historians like Barnes were more similar to their predecessors, the scientific historians, than they (or later scholars) acknowledged. Thus, rather than portraying the shift from scientific history to the New History as a linear trajectory of development from objectivity to a more relativist viewpoint, I argue that New Historians like Barnes at once expressed a greater recognition than his scientific predecessors of how historical writing was the product of its context, while still insisting on his commitment to an ideal of objectivity that divorced the historian from that context.  相似文献

We test whether commonly used measures of agglomeration economies encourage new firm entry in both urban and rural markets. Using new firm location decisions in Iowa and North Carolina, we find that measured agglomeration economies increase the probability of new firm entry in both urban and rural areas. Firms are more likely to locate in markets with an existing cluster of firms in the same industry, with greater concentrations of upstream suppliers or downstream customers, and with a larger proportion of college‐educated workers in the local labor supply. Firms are less likely to enter markets with no incumbent firms in the sector or where production is concentrated in relatively few sectors. The same factors encourage both stand‐alone start‐ups and establishments built by multiplant firms. Commuting decisions exhibit the same pattern as new firm entry with workers commuting from low to high agglomeration markets. Because agglomeration economies are important for rural firm entry also, policies encouraging new firm entry should focus on relatively few job centers rather than encouraging new firm entry in every small town.  相似文献
