Looting, collecting, and the destruction of archaeological resources

Archaeological sites, the material remnants of our human past, are finite and nonrenewable cultural resources that are under constant threat from environmental forces, development activities, warfare, vandalism, and looting. Site looting is the destructive removal of archaeological objects to supply the art market. Looting is part of an economic system, the antiquities market, that works to supply the demand of collectors for archaeological objects. The destruction of archaeological resources by looters is an international crisis and threatens to obliterate the world’s cultural heritage and our ability to understand past cultures. The scale and intensity of the looting problem can be estimated by studying the extent of site destruction in countries of origin and by investigating the sources of antiquities held by collectors. Finding a solution to the problem of looting will require a focus on the demand side of the market (i.e., collectors) instead of the traditional focus on the supply side (looters, dealers)     

用非线性遗传反演方法进行自动静校正

静校正处理是消除近地层影响的一个重要地震资料数字处理方法，在近地表层纵，横向变化复杂，静校正量变化较大的地区，常规静校正方法和线性反演方法均不能解决问题，遗传算法是近年发展起来的一种模拟生物生化过程的较先进的非线性反演方法，对用遗传算法进行静校正的若干问题进行了讨论，说明它是可以解决表层情况复杂地区静校正问题的一个有效方法。     

评价储层含油性的热解参数校正方法及其应用

评价储层含油性时，热解参数Ｓ１＋Ｓ２是一项有效参数。其中Ｓ２相对稳定，Ｓ１则随样品类别或露置时间的不同而发生变化。岩心样品的随钻解分析值比较接近真实，岩屑和井壁取心样品的Ｓ１会明显损失。而目前多数探井心进尺少，大多为岩屑录井。     

Seismic hazard assessment in the Ionian Islands based on observed macroseismic intensities

Catalogues of actual observed intensities are constructed for three towns in the Ionian Islands. They are used for seismic hazard assessment and the results are compared with those obtained by standard approaches; that is, by statistics applied to the data computed from epicentral parameters. The results show that seismic hazard is better assessed using observed rather than computed data, but preparation of the local catalogue presents non-trivial difficulties.     

U—Series Dating of Fossil Bones：Results from Chinese Sites and Discussions on Its Reliability

Calculations,according to some open-system models,point out that while a statistically significant discrepancy between the results of two U-series methods,^230Th/^234U and ^227Th/^220Th(or ^231Pa/^235U),attests a relatively recent and important uranium migration,concordant dates cannot guarantee closes-system behavior of sample.The results of 20 fossil bones from 10 Chinese sites,19 of which are determined by two U-series methods,are given,Judging from independent age controls,8 out of the 11 concordant age sets are unacceptable,The results in this paper suggest that uranium may cycle into or out of fossil bones,such geochemical events may take place at any time and no known preserving condition may securely protect them from being affected.So for the sitew we have studied,the U-series dating of fossil bones is of limited reliability.
