多元族群视野下的华人特性——美国亚裔六大族群的比较   总被引:1,自引:1,他引:0  
根据美国最新公布的各族群的普查、统计及抽样等数据与研究成果,对亚裔各族群进行比较分析发现,华裔、印度裔、菲律宾裔、日裔、韩裔和越南裔,在人口构成与地理分布、人口素质与职业构成、个人与家庭收入、企业数量及收益、自营职业状况等方面各有千秋。华裔呈现两极状态:高层次方面,华裔受教育水平、高级职业比例、企业平均收益等指标,都紧随印度裔之后居第二位;在硅谷和美国新经济中,华裔与印度裔相媲美;低层次方面,华裔贫困率高以及高中以下学历者多,都仅次于越南裔;偷渡移民在亚裔中最为突出。此外,华裔族群经济规模较大,自成一体,具有自我生成、自我扩张的能力,能够消化相当数量的移民。亚裔在美国的差异性与他们在亚洲本土的文化差异度没有直接的相关性,甚至大相径庭。这些差异是移民及其后裔在迁徙过程和异国谋生过程中适应环境所做出的不同的理性选择。中华文化与海外华人的独特性等既有观点,经不起客观数据比较的验证。  相似文献

Using quarterly data for 42 products over the period from 1990 to 2015, we find that there has been a large and growing dispersion of purchasing power across U.S. cities since 1990 and the dispersion varies widely across products. We also find that total factor productivity shock precedes or predicts the rise in regional inequality of purchasing power. We view that the growing regional inequality found in the purchasing power among U.S. cities might have proceeded after nationwide productivity shocks mainly by the cities with higher share of skilled workers through the products with more flexible price adjustments.  相似文献

Airing from 1951 until 1971, ‘The Big Picture’ was the United States Army’s primary means of marketing itself to the U.S. public, particularly between the Korean and Vietnam Wars. Drawing for the first time on archival records concerning the show’s production, this paper documents how information officers sought to escape the stock-footage straightjacket embedded in the show’s origins and showcase an Atomic Age Army standing sentry at the Cold War’s ramparts. Ultimately, they fought dual losing battles against parsimonious budgets and public indifference, while their insistence on content control hampered potential exposure in more appealing prime-time entertainment programmes.  相似文献

Abstract

Recent excavations of the prehistoric pastoralist settlement of Begash, located in the Semirech'ye region of eastern Kazakhstan, provide evidence of one of the earliest pastoralist settlements in the eastern Eurasian steppe region. The archaeological complex at Begash includes a multi-period cemetery and rock art in addition to the settlement—a site complex that is well distributed throughout the koksu River Valley. Excavations at Begash have revealed three major phases of architectural development and six phases of material transition and site use, dated by a series of 34 calibrated radiocarbon AMS dates. These data demonstrate that mobile pastoral populations were active in the Dzhungar Mountains and koksu River Valley (Semirech'ye) as early as 2460 CAL B.C., more than 800 years earlier than previous theories suggested. Pastoralist activity at this domestic locale spans nearly 4000 years, with no archaeological evidence for long-term abandonment of the site in prehistory. Rather the occupational phases of the site are only interrupted by short-lived periods of disuse followed by centuries of re-engagement by local pastoralist communities. Thus, the broadly continuous record of material culture, domesticated faunal remains, and settlement at Begash index a local evolution of herding economies in Semirech'ye throughout the Bronze Age, beginning in the middle part of the 3rd millennium B.C. Ultimately, the data from Begash contribute a new perspective on the dynamic nature of Eurasian mobile pastoralists while also illustrating broad continuity in the settlement ecology of local populations that had a key role in the regional transmission of numerous innovations throughout the Bronze Age and later.  相似文献

Abstract

Over 30,000 miles of railroad and 4,000 miles of canals were constructed in the United States between 1815 and 1861. However, the lack of data has prevented the study of this “transportation revolution” for most cities. This article thus enables a closer study of antebellum travel improvements by constructing a hub-and-spoke network that is capable of estimating the cost of passenger travel from New York City and Philadelphia to any U.S. city in 1836, 1850, 1856, 1859, and 1867. The semi-parametric approach provides an accurate cost estimate by using available historical information to determine the travel cost to all other cities.  相似文献

The benefits of transnational flows and the concern for national security have framed development in the U.S.–Mexico borderlands since the formative beginnings of both nations. As national discourses, trade and security work against each other in borderland spaces, the former requiring openings in the border, the later seeking to control it. This paper considers the material implications of these discourses on the border landscape with particular attention to historical boundary development, urbanization, and impacts of chronic flooding. It argues that material discursive dynamics not only constitute the contemporary landscape, but create spatial incongruities that influence the impacts of natural processes, such as storm water flow. Using the southern Arizona border as a case study, the paper uses archival research to explore the historical geography of chronic flooding in the twentieth century and the shift in dynamics of flooding due to border boundary build up.  相似文献

This study aimed to further test the method, reported by St Pierre et al. (2009), to develop robust chronologies of deposits in limestone caves through U/Th (Uranium/Thorium or U-Series) dating of soda straw stalactites. The chronology of fossil bearing deposits at Blanche Cave was further constrained with thermal ionisation mass spectrometry (TIMS) U/Th dating of 17 additional soda straw stalactite samples, and results were compared to recalibrated 14C ages of charcoal. The results support the assertion that soda straw stalactites can provide ages close to the time of sediment deposition and may be used as reliable chronological markers, particularly for periods reaching or beyond the radiocarbon dating limit. The application of an enhanced cleaning technique facilitated the reduction of detrital Th in samples, significantly increasing age accuracy and precision. Additionally U/Th age accuracy and precision was increased through the application of site-specific measured U/Th ratios to correct for the detrital 230Th component in samples.  相似文献

A team of political geographers analyzes over 5,000 violent events collected from media reports for the Afghanistan and Pakistan conflicts during 2008 and 2009. The violent events are geocoded to precise locations and the authors employ an exploratory spatial data analysis approach to examine the recent dynamics of the wars. By mapping the violence and examining its temporal dimensions, the authors explain its diffusion from traditional foci along the border between the two countries. While violence is still overwhelmingly concentrated in the Pashtun regions in both countries, recent policy shifts by the American and Pakistani governments in the conduct of the war are reflected in a sizeable increase in overall violence and its geographic spread to key cities. The authors identify and map the clusters (hotspots) of conflict where the violence is significantly higher than expected and examine their shifts over the two-year period. Special attention is paid to the targeting strategy of drone missile strikes and the increase in their number and geographic extent by the Obama administration.  相似文献

Abstract

African-Americans in the U.S. military encompass at least two distinct identity groups: a racial status associated with lower support for the wars in Afghanistan and Iraq, and a military status which tends to be more ‘hawkish’ in perspective. This study examines the intersection of these two status characteristics utilizing survey data of American military academy cadets, Reserve Officer Training Corp (ROTC) cadets, and civilian students (n = 5,051). Majorities of military cadets, regardless of race, supported both of these wars more than their civilian counterparts, but African-Americans are significantly less supportive of the wars relative to their peers within each group. African-American cadets support both wars less so than whites and cadets of other races, but African-American cadets supported both wars more than African-American civilians. It appears that racial and military affiliations combine to yield a unique perspective on war, adapting elements of both statuses. These findings support the concept of intersectionality.  相似文献
