Analyses of a 20–30 cm thick, completely combusted ash at the 25 × 70 m Tschudi burn at Chan Chan, northern Perú, contain 52–55 wt% SiO2, 180–210 ppm zirconium and are consistent with coal ash. Soil geochemistry across the burn showed elevated calcium and phosphorus content, possible evidence for reported human cremation. A calcined, 5 g, 4.5 cm skull fragment recovered from the burn was confirmed as human by protein radioimmunoassay (pRIA). X‐ray diffraction showed that the bone had been heated to 520°C. The burn took place c. ad 1312–1438 based on interpretation of a 14C date on carbonized plant tinder.  相似文献

Policy analysts, especially those with an economics orientation, tend to talk in terms of goals that deal with (1) effectiveness in achieving benefits, (2) efficiency in achieving them at low costs, and (3) equity or equality of benefits and costs across various groups. Lay people and also policy analysts with a political science background often supplement those substantive goals with procedural ones that emphasize (1) public participation, (2) predictability of decisions, and (3) procedural fairness that facilitates proving one is deserving of benefits or innocent of wrongdoing. Those procedural goals are often sought even at the expense of the substantive goals, not just as means to scoring higher on the substantive goals. Examples can be given for each procedural goal. The notion of procedures as goals-in-themselves should be distinguished from controversies over transcendentalism-pragmatism, incrementalism- rationalism, and other social value controversies.  相似文献

基于煤炭调运途径优化的江苏省煤炭物流基地建设   总被引:3,自引:1,他引:2  
赵媛  胡玉玲 《人文地理》2008,23(4):64-68
江苏省煤炭资源供需呈生产量小、消费量大,对外依存度不断加大的态势,并且在煤炭调运中省内"北煤南运"运量大、运距长,省外煤炭供应基地较远,大多数铁路线运力已饱和,运输方式、流向单一等一系列问题突出。通过对江苏省煤炭供需和调运中存在问题的分析,提出其煤炭调运途径优化的总体思路是,充分利用国家北煤南运的"海上通道"减轻铁路运输压力,发挥江苏临海沿江的港口优势降低运输成本,建设煤炭物流基地优化调运格局,论文最后论述了建设四大煤炭物流基地的构想:1、以连云港、徐州港为中心的北部煤炭物流基地;2、以盐城港为中心的沿海煤炭物流基地;3、以南通港为中心的"海进江"煤炭物流基地;4、以南京港为中心的沿江煤炭物流基地。  相似文献

We measure the effect of resource‐sector dependence on long‐run income growth using the natural experiment of coal mining in 409 Appalachian counties selected for homogeneity. Using a panel data set (1970–2010), we find a one standard deviation increase in resource dependence is associated with 0.5–1 percentage point long‐run and a 0.2 percentage point short‐run decline in the annual growth rate of per capita personal income. We also measure the extent to which the resource curse operates through disincentives to education, and find significant effects, but this “education channel” explains less than 15 percent of the apparent curse.  相似文献

The Innis model of staple production has been used as the framework for evaluating many Canadian resource trades. This paper argues that Japanese resource trade differs from that with Europe or the United States and that the distinct set of institutional arrangements governing Japanese resource trade requires the modification of the Innis model to recognize this new form of Canadian staple production and trade. The one billion dollars per annum Canada-Japan coal trade provides a detailed case study of the institutional complexity of Japanese resource trade, as revealed through corporate strategies, trade intermediaries, equity investment, loan arrangements, export contracts, and public infrastructure. Minority Japanese investments in joint ventures replace the dominant role of foreign capital in earlier versions of the staples model. The role of finance capital is highlighted by Japanese loans typically exceeding equity investments in size. The high transaction cost of negotiating hundreds of contracts is reduced through the use of sogo shosha (Japanese general trading companies) as intermediaries. Unequal relations are demonstrated by the greater risk borne by local investors as private firms provide equity and public institutions invest in infrastructure. The Quintette mine in northeast British Columbia highlights these risks. Overall, the complexity of the Japanese supply system reduces the bargaining power of any single supplier. However, the stability promoted by the security objectives of the Japanese supply system leads to long-term trading relations that can provide corporate cash flows and maintain community viability during cyclical downturns in the industry. Le modele d'lnnis sur la production des matieres premiéres a servi a analyser les effets du commerce des ressources naturelles au Canada. Le texte maintient que les echanges de ressources naturelles avec lelapon different de ceux qui lient le Canada aux Etats-Unis et à l'Europe, et que la particularité des structures servant à administrer le commerce avec le Japon nécessite une modification du modele d'lnnis vouéà l'analyse des effets de ce commerce. Le texte se penche sur le commerce du charbon entre le Canada et le Japon, dont la valeuratteint 7 milliard$ parannée. Cette étude de cas va permettre de saisir la complexité institutionnelle des échanges ayant trait aux ressources naturelles avec le Japon, perceptible dans les stratégies des corporations, la présence d'intermédiaires, les investissements, les modalités de prêts, les contrats d'exportation et les infrastructures. Les investissements minoritaires des japonais dans des entreprises conjointes remplacent le rôle dominant des investisseurs étrangers caractéristique des modeles antérieurs d'extraction des matieres premieres. Le rôle accru du capital financier est souligné par les prêts des japonais qui exddent habituellement leur achat d'actions. Les hauts cocits transactionnels lie's à la négociation de centaines de contrats est réduit par l'intermédiaire de sogo shosha (compagnies japonaises se spkcialisant dans les échanges entre corporations). Nous constatons l'exis- tence de rapports inégaux olj le gros des risques est assumé par les investisseurs locaux et les agences gou- vernementales qui assurent la mise en place d'infrastructures. La mine Quintette dans le nord-est de la Colombie-Britannique illustre bien ces risques. La complexité du systeme d'approvisionnement japonais réduit les atouts dans les négociations des fournisseurs pris individuellement. It demeure que la stabilité, qui découle des objectifs d'approvisionnement a long terme des japonais, permet d'établir des rapports d'échange durables qui garantissent aux entreprises des revenus persistants ainsi que la prospérité des localites olj se trouvent les opérations d'extraction. Ces localités se trouvent alors soustraites aux effets des cycles économiques.  相似文献

The carbon-13 nuclear magnetic resonance spectra of jet samples from England and Spain resemble those of carbonaceous materials from lignitic and sub-bituminous ranks. This characterization is based on the aromatic/aliphatic ratio of resonances and on the pattern of fine structure. Particularly characteristic of jet is the well-defined fine structure in the aromatic region that may be attributed to phenolic functionalities. This fine structure is found in all English and Spanish samples. Resonances from rapidly moving methyl groups are found in English but not in Spanish samples and may provide a means of distinguishing provenance.  相似文献

我国蒙东地区与东北三省煤炭资源开发的区域合作是建设新兴的蒙东资源基地和振兴东北老工业基地的必然要求。通过在蒙东地区及东北三省的深入调查,发现这两大区域煤炭资源开发的区域合作已经形成一些典型案例,可以分别从上级政府强势干预、地方政府积极推动、中央、地方、企业联动、企业自发参与这四种模式来认识这些案例所反映的区域合作特征、效应与问题。为深入推进蒙东与东北三省煤炭资源开发的区域合作,政府干预应着重协调区域合作的地区格局,促进企业的多元参与,建设跨地区运输通道与生态工程,推进地方政府间的配合与协调。  相似文献
