This paper employs data from selected sample survey areas in the northern Fertile Crescent to demonstrate how initial urbanization developed along several pathways. The first, during the Late Chalcolithic period, was within a dense pattern of rural settlement. There followed a profound shift in settlement pattern that resulted in the formation of large walled or ramparted sites (‘citadel cities’) associated with a more dynamic phase of urbanization exemplified by short cycles of growth and collapse. By the later third millennium BC, the distribution of larger centres had expanded to include the drier agro-pastoral zone of northern and central Syria, termed here the ‘zone of uncertainty’. This configuration, in turn, formed the context for Middle Bronze Age settlement, and the pattern of political rivalries and alliances that typified the second millennium BC. Evidence is marshalled from archaeological surveys and landscape analyses to examine these multiple paths to urbanization from the perspectives of (a) staple production within major agricultural lowlands; (b) the shift towards higher risk animal husbandry within climatically marginal regions; (c) changes in local and inter-regional networks (connectivity); and (d) ties and rights to the land. Textile production forms the core of the proposed model, which emphasizes how the demand for wool and associated pasture lands opened up new landscapes for agro-pastoral production and settlement. The resultant landscapes of settlement are then compared with the picture in the southern Levant where a more restricted zone of uncertainty may have limited the opportunities for agro-pastoral production. 相似文献

We assess the tendency for the public to use group‐centric policy evaluations with evidence from a survey experiment concerning two issues within the social policy domain, health care and aid to cities. By randomly varying target group identity within each issue and using both negatively and positively regarded groups our evidence shows that differences exist in the tendency for members of the public to use group‐centric heuristics. Group‐centric evaluations are related to party identification and political ideology. Across both issues conservatives and Republicans are more likely than liberals or Democrats to adopt a group‐centric heuristic. Partisan and ideological differences suggest that established theories miss the mark by emphasizing how universal policy designs are preferred to designs that target unpopular groups. 相似文献

Federalism is often praised for being able to accommodate diversity within the confines of a single state while preventing secession. Federalism, however, is fraught with tensions and instability. Federalism is typically adopted as a second-best alternative among actors whose first choice is either a more centralized state or a more decentralized state. These preferences persist over time. Instability in federation, then, comes from federal partners pushing in opposite directions at the same time. From this dynamic comes the much-examined propensity for secessionism to develop within federations. Largely unexamined in the literature on federalism, but equally problematic from the standpoint of stability, is the equal and opposite risk of consolidation (or centralization). This article examines sources of federal instability by exploring the origins and evolution of federalism. I use examples from Canada to demonstrate the extent to which my argument is applicable to real world federations. In conducting the exploration, we come to understand how federations can be both unstable and durable. 相似文献

This paper provides a critical review of recent geographical scholarship on place naming and contends that aural aspects of naming have yet to be fully worked into the research agenda. To begin to address this gap in the literature, we consider pronunciation to be an important element of the cultural politics of place naming within post-colonial societies. In asserting links between speaking and naming we are contributing to recent scholarship in cultural geography that has moved beyond the visual to consider a wider sensory spectrum in the constitution of place. Our case material is drawn from Aotearoa/New Zealand where conservative reactions to sympathetic pronunciations of Maori names by media personalities are a frequent occurrence. By way of example, we interpret selected examples of unsolicited comment gleaned from newspapers during the period 1994-1999. We conclude that identity is at least in part narrated through place-referenced linguistic tactics such as pronunciation. Cet article se veut un inventaire critique des récents travaux académiques sur la toponymie et soutient que la question des aspects 'auditifs' du nom mérite davantage l'attention des chercheurs. Afin de remédier à ce manque dans la littérature existante, nous suggérons que la problématique de la prononciation constitue un élément important des débats culturels entourant l'attribution de noms de lieux, surtout chez les sociétés postcoloniales. En insistant sur les liens entre le fait de parler et celui de nommer, notre discussion s'inscrit dans les travaux récents en géographie culturelle allant au-delà du visuel afin de concevoir une gamme sensorielle beaucoup plus large en ce qui a trait à la conception du lieu. Nos données sont tirées de la Aotearoa/Nouvelle-Zélande où les réactions conservatrices sont fréquentes lorsque des noms d'origine Maori sont utilisés par des personnalités médiatiques. A titre d'exemple, nous interprétons des commentaires receuillis dans les journaux entre 1994-1999. Nous concluons que l'identité est en partie rattachée à des références toponymiques et linguistiques tactiques telles que la prononciation. Este papel da un análisis crítico de reciente erudición geográfica sobre el nombramiento de lugares y afirma que el aspecto auditivo del nombramiento todavía no forma uno de los asuntos de investigación. Para empezar a cerrar esta brecha en la literatura, consideramos que la pronunciación constituye un elemento importante en la política cultural del nombramiento de lugares dentro de las sociedades pos-coloniales. Al acertar vínculos entre el hablar y el nombrar contribuimos a erudición reciente en la geografía cultural que se ha ido más alláde lo visual para considerar un espectro sensorio más amplio en la constitución de lugar. La materia de nuestro estudio viene de Aotearoa/Nueva Zelanda donde son frecuentes las reacciones conservadores a pronunciaciones comprensivas de los nombres Maorí por personajes de los medios de comunicación. Como ejemplo, interpretamos ejemplos de comentarios no solicitados, recogidos de periódicos de los años 1994 a 1999. Concluimos que, por lo menos en parte, la identidad es narrada por tácticas lingüísticas que se refieren a un lugar, tal como pronunciación. 相似文献

Aside from a number of early prophesies of abundant and cheap nuclear power, and increased supplies of isotopes for medical research, diagnosis and therapy, visions of the Atomic Age were overwhelmingly troublesome in the aftermath of Hiroshima. Not only did nuclear Armageddon seem likely to many observers, the steps taken to enhance national security in the United States cast classes of citizens into the doleful category of “security risk.” Scientists were among those feared—a stunning (and almost instantaneous) change from their perception in August 1945 as the nuclear wizards who brought World War II to an end. National security was the dominant factor in this transformation, but there were nuances to it. This article attempts a taxonomy of the ways in which scientists were viewed in the United States. 相似文献
