This article formulates and tests set covering and related models with spatial characteristics for selecting sites that provide habitat for species that are identified as "critical" (e.g., typically threatened, endangered, or rare), thereby enhancing their persistence. The first two models presented require the creation of a core area for each critical species and a buffer zone surrounding the core, with and without being constrained to include at least one representation of each and every common (i.e., noncritical) species. The final model aims at minimizing costs of protecting predetermined numbers of common species while all critical species remain covered and buffered. These models are implemented for occurrence data of terrestrial mammals in Oregon. They enable, among other things, a comparison between the budgetary impacts of reserve networks with and without buffering rings for critical species, and a determination of the marginal cost of common species protection.  相似文献

Between 2011 and 2015 archaeological fieldwork was conducted in the Archaic through Late Antique harbours associated with Burgaz on the Datça Peninsula in south‐west Turkey. This work focused on survey and documentation of built features associated with the four harbours, limited stratigraphic excavation, and identification of shipwrecks and seafaring activity outside the harbours. The results offer new insights into the growth, expansion, and eventual abandonment of the port complex, its development alongside the urban settlement, and its changing maritime dynamics in light of economic shifts across the peninsula and the eastern Mediterranean.  相似文献

How urban characteristics change with total population, their scaling behavior, has become an important research field since one needs to better understand the challenges of urban densification. Yet urban scaling research is largely disconnected from intra-urban structure, and this seriously limits its operationalization. In contrast, the monocentric model of Alonso provides a residential choice-based theory to urban density profiles. However, dedicated comparative static analyses do not completely solve how the model scales with population. This article bridges this gap by simultaneously introducing power laws for land, income and transport cost in the Alonso model. We show that the equilibrium urban structure of this augmented model matches recent empirical findings about the scaling of European population density profiles and satisfactorily represents European cities. This result is however not compatible with the observed scaling power of housing land profiles, and challenges current empirical understanding of wage and transport cost elasticities with population. Our results call for revisiting theories about land development and housing processes as well as the empirics of agglomeration benefits and transport costs.  相似文献

ABSTRACT

Explorations of the predictive relationship between party system fragmentation and social cleavages beyond a single dimension remains an undeveloped area of research, one which rarely accounts for the changing technological landscape where parties now compete. This case study of New Zealand's 2017 election campaign on Facebook contributes to this area. It reveals an environment where parties compete within social cleavages for support, and users demonstrate a diverse preference for cleavage appeals. The findings also offer a compromise between the competing theories about New Zealand’ social cleavage structure. Finally, we revisit the predictive relationship between party system size and social cleavages in a postdictive fashion, demonstrating the continued explanatory power of cleavage structure, this time with data derived from social media.  相似文献

This article tests a model for the political economy of the Wari Empire (AD 600–1000) of Peru. This model divides the empire into core and periphery zones. In the core, Wari political economy was organized to extract surplus agricultural production to feed the capital. In the periphery, the Wari strove to extract prestige goods. We suggest that there is a strong relationship between where the empire chose to locate its centers in the periphery and the political complexity of the local population in which the center was placed. We argue that in areas of low political organization sites should be located near the geographic center of a population. These sites will tend to function as local administrative centers geared toward the organization and exploitation of the area's wealth potential. In areas with more complex political organization sites should be located on the margins of a population. These sites should have functioned as gateway centers controlling, or at least profiting from, interregional exchange. Our model was systematically tested through the use of Geographic Information Systems (GIS). The results suggest that much of the variability found in Wari site placement in the periphery can be explained by differences in local sociopolitical complexity.  相似文献

This article forms part of an ongoing debate on rights and the use of the term 'indigenous', which has so far included exchanges in Current Anthropology , the New Humanist , and ANTHROPOLOGY TODAY , as indicated in the bibliography. The authors here respond specifically to an article by Adam Kuper, published in Current Anthropology and the New Humanist . Professor Kuper has been invited to respond and has indicated his intention to do so in the forthcoming issue of ANTHROPOLOGY TODAY . Readers are invited to contribute their own views to the debate.

Shifts over time in faunal representation in Northwest Coast archaeological sites have been viewed as reflecting changes in economic organization and social complexity. We use fish faunal data from the Parry Lagoon Midden (site DgRv-006) in the Salish Sea region of coastal southwestern British Columbia, Canada, to evaluate the relationship between change in subsistence strategies and community organization. We describe and compare fish assemblages recovered from a shell midden generated by habitation at two sequentially occupied village sites. The lower midden layers include faunal remains derived from the Marpole Period plankhouse village occupation at site DgRv-003 (1500 to 1300 cal BP), while the upper layers were generated during the occupation of a Late Period plankhouse within site DgRv-006 (1000 to 600 cal BP). We compare the two faunal records to ascertain if subsistence re-organization accompanied the social change associated with abandonment and later re-establishment of a village in the Dionisio Point Locality. Results indicate continuity of a diverse fishing economy for the two occupations, and therefore across the Marpole to Late Period transition. This study adds to the recent trend in Northwest Coast archaeology to reconsider the long-standing view that social and subsistence change necessarily occurred in tandem.  相似文献

During its annual surveys of the Turkish coast in the 1970s and 1980s, the Institute of Nautical Archaeology discovered two early Archaic (7th‐ to early‐6th‐century BC) shipwrecks at Kekova Adas? (Antalya region) and Kepçe Burnu (Mu?la region); Dokuz Eylül University's Institute of Marine Science and Technology is currently involved in survey of the region. The wrecks, marked by a primary cargo of basket‐handle amphoras, indicate exchange between Cyprus and the cities of coastal Asia Minor and Corinth. Such Iron Age internationalism may have been driven by an interest in processed agricultural goods such as olive oil. © 2010 The Authors  相似文献

Previous research on remote nineteenth-and early twentieth-century Indigenous missions in northern and central Australia point to their often tenuous existence and the complex nature of engagements between Christian Missionaries and Indigenous people. This paper explores the contribution and significance of Indigenous production of wild foods in the context of one such settlement located at Weipa on Cape York Peninsula, north eastern Australia. It is premised on the assertion that investigation of the economies of these often remote settlements has the potential to reveal much about the character of cross-cultural engagements within the context of early mission settlements. Many remote missions had a far from secure economic basis and were sometimes unable to produce the consistent food supplies that were central to their proselytizing efforts. In this paper it is suggested that Indigenous-produced wild foods were of significant importance to the mission on a day-to-day basis in terms of their dietary contribution (particularly in terms of protein sources) and were also important to Indigenous people from a social and cultural perspective. We develop this argument through the case study of culturally modified trees that resulted from the collection of wild honey.  相似文献

Abstract

Mark Blitz begins his book Plato’s Political Philosophy by making a strong case for Plato’s continuing relevance to us. The book’s three parts are centered on three dialogues of special importance to Blitz’s topic: the Laws, the Republic, and the Statesman. Blitz also pulls into his discussion other dialogues that illuminate the teachings of these three central ones. Blitz’s analyses of the dialogues are illuminating. He lays out the dialogues’ intellectual pathways and gives us an important sense of their meaning. In addition to his examination of particular dialogues, Blitz also gives us rich discussions of four key concepts that underlie and are found throughout Plato’s works: nature, wonder, perplexity, and laughter. The book lacks a deeper discussion of the view that we should be guided by nature in determining our ends. Also missing is a better appreciation of both the challenge posed to philosophy by piety, and the attraction of institutions of modern republics. And we could have a better understanding of the limits of a rational politics in the Statesman. Plato has difficulty finding a place for the philosopher in the city, and this could come through more clearly in Blitz’s account. But these shortcomings are minor when set against the book’s strengths. Its synoptic analyses can help guide those new to Plato. But there is also much here for mature scholars in Blitz’s detailed and careful exploration of Plato’s more important concepts and arguments.  相似文献
