Paleozoologists have long used taxa represented by ancient faunal remains to reconstruct paleoenvironments. Those ancient environments were the selective contexts in which hominin biological and cultural evolution took place. Knowing about those particularistic selective environments and how organisms responded to them is increasingly seen as critically important to identifying both how biota will respond to future (to some degree anthropogenically driven) environmental change, and biological conservation and management applications that will ensure sustainability of ecological resources and services. Reconstructing paleoenvironments requires knowledge of species’ ecological tolerances, geographic ranges, habitats, environments, and niches. It also requires assumptions that extant species had the same ecological tolerances in the past as they do today and that changes in taxonomic composition or abundances reflect environmental change rather than sampling or taphonomic factors. Greater knowledge of ecological processes as well as increased analytical sophistication in paleozoology is providing increasingly rigorous and detailed insights to paleoenvironments. 相似文献

Relying heavily upon historical records to build archaeological chronologies, many Korean historical archaeologists question the utility of radiocarbon dating. To challenge this tendency, we test a model based on historical records by analyzing radiocarbon dates. We dated two bulk samples from Hongryeonbong Fortress II, Seoul, South Korea, which is known historically to have been occupied between a.d. 500 and 551. By dividing bulk samples into smaller aliquots, we dated 40 subsamples and statistically estimated consensus dates. The consensus dates do not support expectations of the historical model, as they do not lie within the temporal range provided by historical records. We propose an alternative model that explains both the radiocarbon dates and the historical records. It is suggested that radiocarbon dating can be successfully applied to the reconstruction of historical periods and is a way of mitigating possible biases of models based solely on historical records. 相似文献

The handle‐shaped artefact is a special jade object of the Three Dynasties (c.2000–200 bc ) period. The manufacturing technology and function of the handle‐shaped artefacts are widely questioned. In this paper, two handle‐shaped artefacts from Yinxu (c.1300–1046 bc ) are tested by digital microscope, Raman spectrometer and scanning electron microscope. The results indicate that the handle‐shaped artefacts might be made in four steps, namely rough shape cutting, edge reforming, handle making and single‐side polishing. It also suggests that the handle‐shaped artefacts might be used as sacrificial offerings, but not as hairpins or handles. 相似文献

A bicycle tourism destination is composed of complexes of different attributes that are crucial for the determination of tourist satisfaction levels. However, the relative impact of sector-specific destination attributes on bicycle touring and leisure cycling experience and frequency has been both poorly understood and studied. This study is an attempt to fill this literature gap by exploring a demand-side perspective on the important contributors of overall satisfaction with cycling experience and the key determinants of cycling frequency. The 28 sector-specific destination attributes were drawn from the relevant literature, and then modified by a panel of industry experts. Using exploratory factor analysis, three destination-specific attribute-level satisfaction factors were identified in descending order of satisfaction degree: ‘provision of signage services,’ ‘provision of safety and emergency services,’ and ‘quality of bicycle routes.’ Among these factors, ‘provision of safety and security services’ and ‘provision of signage services’ were found to be the most important contributors to overall satisfaction. Finally, ‘monthly income’ was proven to be a significant predictor of cycling frequency. This study is of great importance as there is a growing body of evidence that the use of bicycle for leisure, recreation, and tourism is undergoing a resurgence worldwide. The findings of this study may be of interest to scholars in Western countries where bicycle tourism is mature and highly developed and in Asian countries where the sector is at an early stage of development. Since bicycle touring and leisure cycling experience and frequency can be increased by modifying destination marketing and management practices, the government and industry sectors should focus more attention on ensuring the provision of multi-functional grocery and convenience stores along designated bicycle routes, developing an informative and visible signage system for designated bicycle routes, and targeting middle- to high-income bicyclists with diverse bicycle touring and leisure cycling experience options. 相似文献

Given significant variation in population turnover and stability across neighborhoods, this study examines why renters stay in or leave certain neighborhoods. It is the first to analyze how neighborhood characteristics influence renters’ decisions to move within the neighborhood as well as how these decisions are interrelated with their housing tenure transitions and race. Results demonstrate that homeownership rates have a significant, positive association with the probability that renters stay and/or purchase homes in the current neighborhood. Both the tenure composition of the housing stock and higher neighborhood satisfaction appear to be central in understanding this association. Results also suggest that nonblack renters are more likely to leave neighborhoods that experience growth in the percentage of the black population, while blacks are more likely to stay and purchase homes within such neighborhoods. 相似文献

This paper examines modern Korean politics through the framework of Giorgio Agamben's theories of sovereign power, bare life, and the state of exception. Though his political analysis draws from the European history, we contend that the nature of his method attests to the possibility of analogical examples in non‐Western places. Thus, we argue that a postcolonial encounter with Agamben may enrich our understanding of sovereignty and political geography. In the Korean context, such an analysis needs to consider that sovereign power has been shaped by the itineraries of colonialism and empire. Korea's political space is deeply marked by the legacy of Japanese colonialism, the imperial interventions by the U.S., and the division of the peninsula. Thus, Korea offers a valuable lens through which to read Agamben's critique of sovereignty. Our paper offers such a reading to argue that a state of exception functions as the underlying nomos for postcolonial Korea. 相似文献

In the face of the reemerging threat of preventable diseases and the simultaneous vaccine risk controversy, what explains variations in Americans’ policy preferences regarding childhood vaccinations? Using original data from a recent nationwide Internet survey of 1,213 American adults, this research seeks to explain differing public opinions on childhood vaccination policies and related issues of governance. As Mary Douglas and Aaron Wildavsky's grid‐group cultural theory of policy preference formation suggests, cultural biases have a significant impact on the formation of preferences toward various vaccination policies. Hierarchs are in support of mandatory vaccination, oppose religious and philosophical exemption, and believe the government should preside over vaccination‐related decisions. Fatalists strike a bold contrast in their opposition to mandatory vaccination policy and support for religious and philosophical exemptions and the role of parents in deciding on vaccinations. Falling between hierarchs and fatalists, egalitarian support for vaccinations is stronger than individualists‘. 相似文献
