U.S. immigration policy has been the subject of considerable debate in recent years. Previous research has focused on how temporal variation in federal policy has altered the migratory behavior of immigrants. The effect of spatial variation in enforcement remains untested. Relying on the criminological distinction between general and specific deterrence, we argue that high rates of enforcement are unlikely to encourage undocumented immigrants to self‐deport. We also examine the effects cultural and economic immigration policies adopted by the states. Previous research suggests that migrants will choose to remain in states with favorable environments, but this claim has not been directly tested. We draw on data from the Mexican Migration Project (MMP) to address these gaps. MMP data are supplemented with government data on federal enforcement obtained from Immigration and Customs Enforcement (ICE) and measures of state policy. Our findings suggest that higher rates of enforcement and the establishment of negative policy environments do not encourage undocumented immigrants to leave the United States at a higher rate than their documented counterparts do. Rather, high enforcement contexts exaggerate the differences between documented and undocumented migrant behavior, with undocumented migrants staying longer. Liberal state policies have no discernible effect. 相似文献

Personal appearance in general—and the grooming of hair in particular—has long held a position of interest in historical, art-historical, and literary scholarship. The same cannot be said of archaeology, and the material aspects of personal grooming in the construction and communication of identity have not been fully synthesized. As a result, little attempt has been made to understand the social role of hair in less well documented societies, such as those of early medieval northern and western Europe. This paper considers archaeological, iconographic and documentary evidence for the significance of, and physical engagement with hair in early medieval northern and western Europe, and offers a model for the interpretation of grooming as a social phenomenon. It is argued that grooming was a socially meaningful practice, and that it played a key role in the construction of early medieval identities, as well as in the maintenance and manipulation of boundaries and distinctions between individuals and groups. 相似文献

Based on an ethnographic field investigation conducted on the matrilineal–matrilocal Garo community of Bangladesh, this article provides a historical account of local environmental struggles to draw attention to the interconnections between gender, environment and sustainable resource management. From a feminist political ecology perspective, the article argues that interacting with traditional culture, forest ecology and changing processes of centric resource governance, gender remains a salient variable in environmental issues. Local contexts of gender dynamics help configuring local people's mode of participation in environmental struggles as well as being the consequence of those struggles. Findings suggest that Garo women and men have sustained gender specific roles and interests through their struggles to ensure control over forest lands and tree resources. Furthermore, they have developed a class-based relationship with forest ecology which must be acknowledged in forest policies. 相似文献

In this paper we show the results of a study concerning 42 axes, mainly discovered in the Copper Age pile dwellings of Ljubljansko barje (central Slovenia) and in the neighbouring areas of Caput Adriae. The studied shaft‐hole axes, characterized by homogeneous typology but slightly different raw materials, have been called ‘Ljubljana‐type’ axes (Lt). The raw materials show a common OIB‐like signature and metamorphic and spilitization features that recall oceanic conditions. The typological and geochemical characteristics and the very high percentage of Lt axes among the polished stone axe assemblages of Ljubljansko barje suggest that the raw material was probably gathered from one or more relatively small outcrops close to Ljubljansko barje. Similar igneous rock types outcrop in the presumably Palaeozoic diabase/shale complex (Eisenkappler Diabaszug), intruded by the northern Karawanken plutonic belt. A probable provenance from this area, particularly rich in copper ore deposit, would confirm the important role of Ljubljansko barje as a metallurgical district, as well as a strong relation between lithic raw materials and Cu cultivation districts during the Copper age. 相似文献

Multi‐isotope fingerprinting (sulphur, oxygen and strontium isotopes) has been tested to study the provenances of medieval and Renaissance French and Swedish alabaster works of art. Isotope signatures of historical English, French and Spanish alabaster source quarries or areas are revealed to be highly specific, with a strong intra‐group homogeneity and strong inter‐group contrasts, especially for Sr and S isotopes. The chosen combination of isotope tracers is a good basis for forensic work on alabaster provenance, allowing verification of hypotheses about historical trade routes as well as identification of fakes and their origin. The applied analytical techniques of continuous flow isotope ratio mass spectrometry (CF–IRMS) and thermal ionization mass spectrometry (TIMS) only require micro‐samples in the low‐milligram range, thus minimizing the impact on the works of art. 相似文献
