Research within the last 3 to 5 years is summarized for the southern part of the southwestern United States and adjacent northwest Mexico. In an effort to identify important new sources of information, the literature of contract archaeology is cited, along with more widely available journal and book publications. Topics considered include Late Archaic farmers, early ceramic villages, subsistence and agricultural technology, settlement stability and residential mobility, community organization, and developments of the late prehistoric period sociopolitical complexity.  相似文献

Caledogonia globosa gen. et sp. nov. is considered to be a member of the Myophoriidae following the classification of Newell & Boyd (1975). It is a more evolved genus than Agonisca Fleming from the Ladinian of New Zealand. Both are probably the descendants of Neoschizodus of the Andean-West Antarctic region, a dispersal route on the southern Gondwanaland coastline. Caledogonia was probably a rapid burrower in a high energy paleoenvironment. It occurs in a rhythmic sequence of greywackes and conglomeratic shell beds that lie on pre-Triassic basement. Like the associated bivalves, Maoritrigonia and Manticula, Caledogonia is an endemic genus of the Late Triassic Maorian Province.

Caledogonia globosa gen. et sp. nov. est a rapporter aux Myophoriidae, d'après la classification de Newell & Boyd (1975). Plus évolué que le genre Agonisca Fleming du Ladinien de Nouvelle Zélande, il descend probablement, comme celuici de Neoschizodus représenté dans la region Andine et West Antarctique, zone de dispersion faunique de la cote Sud des Terres de Gondwana. Caledogonia, était un fouisseur actif dans un paléoenvironnement de haute énergie et de sédimentation rapide. On le trouve aujourdhui dans une séquence rythmique de grauwackes alternant avec des lumachelles et conglomérats, transgressive sur le substratum antétriasique. Comme les bivalves associés Maoritrigonia et Manticula, Caledogonia est un genre endémique de la province máorie du Trias supérieur.  相似文献

This article starts by defining the term “powered cultural landscapes” and then provides a brief history of research on this topic in historical archaeology, starting with the settlement pattern paradigm that did not use the word “landscape,” and progressing to the landscape paradigm and the subsequent increasing use of the word “power” in cultural landscape research. Topics of research initially addressed landscape power dynamics between classes, followed by racial, ethnic, and finally gender power dynamics. Frameworks for analyzing power dynamics have progressed from the Marxian domination and resistance framework for class and racial power dynamics, followed by feminist analyses of male domination, to the recent development of a feminist inclusive heterarchical model of power dynamics.  相似文献

The open, multilevel nature of U.S. policymaking enables interest group activity throughout the policy process. At policy implementation, groups attempt to secure benefits or ameliorate legislated effects by devising cooperative or conflictual strategies to influence outcomes, especially when agency officials have discretion to design rules and negotiate agreements. Investigating group “street‐level” activity with respect to the Endangered Species Act, this research finds that policy context and resources shape the degree of information and access available to groups, which influences the strategies groups adopt. Groups with access and specialized information will attempt to change or influence policy outcomes cooperatively. Groups with limited technical information are more likely to fight implementation.  相似文献

This article explores how women forest workers’ perceptions of restructuring are related to their work identities. Drawing on semi‐structured interviews with 29 women working in subsidiaries of a multinational forest company in northern Saskatchewan, I describe how women workers selectively drew on traditional mill worker and flexible worker identities to legitimize and delegitimize restructuring. Women's understandings of themselves as workers were shaped by their paradoxical relationships to standard forest processing work. Some women with previous experience working in low‐waged service industries adopted worker subjectivities that legitimized restructuring and valued flexibility, individual empowerment, and mobility. Other women delegitimized restructuring, referencing traditional characterizations of forest work that valued community stability, collective resistance, and security. Many women, however, neither consistently legitimized nor delegitimized restructuring throughout their interviews. This last group's ambiguous portrayal of work and restructuring demonstrates the identity dilemmas faced by new entrants to declining industrial sectors. Restructuring interrupted women's narratives of having found a “good job” in forestry and prompted the renegotiation of their understandings of mill work. This article contributes to our understanding of restructuring in resource industries by drawing attention to how worker identities, gender, and industrial change are interrelated.  相似文献

The Earned Income Tax Credit (EITC) is widely recognized as the United States’ most effective contemporary policy for reducing poverty, and scholars have found that it elevates recipients’ sense of social inclusion. This raises the question of how it influences recipients’ civic engagement, namely their attitudes about government and political participation. We draw on policy feedback scholarship to consider expectations. Then we use a unique dataset to compare recipients of the EITC, Aid to Families With Dependent Children/Temporary Assistance to Needy Families, and nonrecipients of either policy in order to identify how policy features are related to political attitudes and behaviors. We find that despite the benefits they receive, EITC recipients experience low external political efficacy, but are more likely to be politically active than their peers.  相似文献

In the twenty-first century historical archaeologists have increasingly drawn on post-colonial theory to analyze the European conquest and colonization of the Americas, Australasia, and Africa. However, few have employed feminist theories to gain insights into the patriarchal power dynamics that were fundamental to institutionalized colonial ideologies and practices. This paper provides feminist theorizing of new concepts and a heterarchical model of multiple interacting powers that increase understanding of complex gender and sexual power dynamics between colonizers and colonized.  相似文献

Criteria developed to distinguish between the mandibles and mandibular teeth of sheep and goats are evaluated using modern specimens from the collections of the National Museum of Natural History and the Field Museum of Natural History. Certain teeth prove to be quite reliable in this regard (dP3, P3, P4). Other dental elements, however, are not reliable and should not be used in dental based identifications of these closely related species (dP4, M1, and mandibular bones). Overall, the identification of sheep dentition using these criteria is more reliable than it is for goats. However, the generally greater likelihood of incorrect identification of goat teeth and mandibles means that specimens identified as sheep are likely to contain high proportion of misidentified goats. Both the proportion of remains that can only be classified as ‘Ovis-Capra’ and the proportion of incorrectly identified teeth and mandibular bones varies with age, with identifications of younger and older animals less reliable than those of animals in the 1.5–6 year age range. Reliability of identifications increases when more criteria and more elements are used. Identifications based on whole mandibles with complete tooth rows are quite reliable. However, the proportion of specimens likely to be classified as ‘Ovis-Capra’ also increases in whole mandible identifications, especially in goats. Systematic differences in the proportions of indeterminate and incorrect identifications have a significant impact on species-level dentition-based harvest profiles. Recommendations are made for the use of dentition and long bone based harvest profiles in the study of sheep and goat exploitation strategies.  相似文献

This research applies a task‐based approach to measure and interpret changes in the employment structure of the 168 largest U.S. cities in the period 1990–2009. As a result of technological change some tasks can be placed at distance, while others require proximity. We construct a measure of task connectivity to investigate which tasks are more likely to require proximity relative to others. Our results suggest that cities with higher shares of connected tasks experienced higher employment growth. This result is robust to a variety of other explanations including industry composition, routinization, and the complementarity between skills and cities.  相似文献
