Using data describing the historical distribution of county seats in the United States, we (1) replicate the traditional ratio-variable test of the size-density law, (2) test a new multivariate, nonratio form of the law, and (3) introduce an alternative method of testing, one which avoids three possible problems in traditional analyses: ratio-variables, multicollinearity, and logarithmic transformation. 相似文献

A shipwreck from the early 3rd century BC was discovered in the Black Sea's suboxic depths off Ere?li, Turkey, during the 2011 E/V Nautilus expedition. Remote investigation revealed the trawl‐damaged remains of a merchant ship carrying multiple amphora types associated with Aegean and Pontic production areas. Also discovered were elements of the ship's hull that show evidence of both pegged mortise‐and‐tenon and laced construction. The wreck provides crucial archaeological evidence for both maritime connectivity and ship‐construction methods during a period of political and economic transition. 相似文献

长江下游西部北阴阳营文化、薛家岗文化随葬猪下颌骨的习俗比较广泛,汉水流域甚至发展为主要以猪下颌骨随葬的葬仪。随葬猪下颌骨所彰显的财富与地位特征逐渐变强后再渐弱。距今7000年左右,即在随葬猪下颌骨的最初阶段,只体现出一定的财富属性。距今6000—4500年,随葬猪下颌骨隐含的财富与地位特征最强。之后,这种习俗渐趋消失,与财富、地位的关联性也微乎其微。随葬猪下颌骨的习俗可能是与黄河流域社会上层交流的要素之一。 相似文献

《隸續》載《米巫祭酒張普題字》全文,宋洪适對碑文作了綜述,云:"此碑有天師道法及祭酒、鬼兵字,而云受《■經》十二卷,蓋諸張妖黨指傳授之約,頗合史氏所載。"本文對"張普題字"以及該碑所在地作了分析。傳授之約或是祭酒向初入教的道徒傳授道家關於宇宙原始以及長生之道的基本觀念。此碑實是現存罕見的爲後人留下史籍未備的五斗米道入道儀式記録。 相似文献

This paper offers a snapshot of the 2015 El Niño drought among Min people in Papua New Guinea's West Sepik and Western Provinces. Local assessments of food, water, and health show variation between locations, but with an overall tendency for the drought's effects to spread from lower to higher elevations as the drought progresses. This zone is in the hinterland of the Ok Tedi Mine, and the drought's regional impact was intensified by Ok Tedi's abrupt closure when low water in the Fly River stopped shipments of concentrate and cut off fuel and food supplies. The decision to close the mine was accompanied by the mandatory ‘repatriation’ of workers and their families to ‘home’ communities in the drought‐stricken hinterland. This, combined with deteriorating regional links, has eroded the capacity of Min communities to weather the drought, suggesting that we must look beyond the garden when calculating El Niño's costs. 相似文献

HEDONIC PRICING WHEN HOUSING IS ENDOGENOUS: THE VALUE OF ACCESS TO THE TRANS‐ISRAEL HIGHWAY*
下载免费PDF全文

Standard hedonic house pricing assumes that house prices are independent of the intangible to be priced. A methodology is proposed in which the supply as well as the demand for housing depends on the intangible. The methodology is applied to value access to the Trans‐Israel Highway (TIH). Using spatial panel data (2002–2008) we show that TIH had two effects on the housing market. It increased house prices in locations with greater access to TIH, and it affected housing construction. Standard hedonic pricing would have underestimated the value of access because it ignores the effects of housing construction on the intangible to be priced. House prices began to increase three years before TIH was inaugurated, but housing construction did not anticipate the inauguration of TIH. 相似文献

Recognition and respect for sexual minorities in Hong Kong is still a contested area. Public sexual identity politics in Hong Kong has been framed by traditional Chinese gender ideology and imported Christian beliefs which are profoundly negative. Focusing on the interpersonal relationships in three spheres of life, the research adopted the sociological perspective of personal life and the feminist geographers’ idea of spatialization of identity management to analyze how the sexual self of sexual minorities has been marginalized and excluded in intimate social spaces of family, church communities and schools in Hong Kong with specific spatial practices and different forms of power/knowledge. By examining overlooked intimate injustice in personal life, this study illustrates that identity conflicts between Christianity and non-heterosexuality in everyday life is constructed through misrepresentation, misrecognition, harassment and exclusion in intimate relationships. Different types of knowledge are being used to reiterate pre-existing norms and institutionalized patterns of cultural value that constitute the sexual minorities as comparatively unworthy of respect. These micro-political processes involve both conformity and resistance to gender and sexual stereotypes. Participants managed to develop spatial coping strategies such as concealment, compartmentalization, confrontation and alternative sources of support to manage their lives with dignity and self-esteem. 相似文献

The quick and accurate identification of post-earthquake rescue objects can minimize the casualties and property loss caused by earthquakes. With the rapid development of remote sensing technology, rescue objects can be identified through high-resolution remote sensing images. There are two main categories of approaches to identify rescue object through high-resolution images: automatic extraction by a computer and visual judgment by professionals. Although results can be obtained quickly by using automatic extraction, the accuracy of the results is unacceptably low. For visual judgment, the large demands for time and professionals restrict its wide practical application. In this study, we introduce crowdsourcing into the identification of post-earthquake rescue objects. First, we integrate the advantages of the computer and crowdsourcing, which means that the computer takes advantage of the speed of information processing, while crowdsourcing makes full use of human recognition capabilities. Second, we take visual judgment tasks out of the hands of professionals and entrust the tasks to workers in a crowdsourcing platform. Not only are the human resources infinite, but we can also improve the efficiency of identifying rescue objects. Third, we propose a crowdsourcing model that improves the quality of the results and saves human resources. Finally, experimental results demonstrate that our solution is feasible. 相似文献
