A survey was conducted in Lefkada Island in Greece, where 200 interviewees took part in order to consider whether they wish to voluntarily participate in the excavation and restoration of the ancient theater of Lefkada. Half of the interviewees were given information on the history of the site and then were asked to fill out a questionnaire. The other half of the interviewees were given no historical information on the archeological site and also were asked to fill out a questionnaire. The interviewees who were not given any information on the history of the site briefed on the history and then were asked to fill out another questionnaire. The purpose was to observe the different responses that the interviewees gave before and after being informed. This study aims to compare the WTP （Willingness To Participate） for this public good among those who were informed and those who were not.展开更多

However, the AFT ages from surface outcrops range broadly and do not show an apparent relationship between age and elevation. This work provides a multiple low temperature thermochronological dataset including zircon and apatite （U-Th）/He ages （ZHe and AHe）, and AFT ages from a 1000-m-deep borehole at the Jiaojia goldfield in the northwest of Jiaodong Peninsula. ZHe, AFT and AHe ages range from -100-70, -85-50 and -65-50 Ma, respectively. These data conform to the principles of age vs. closure temperature and age vs. elevation and thus can be employed to estimate the exhumation history. Based on the density histogram of fission track length calculation, thermal history modeling, and previously published AFT ages from the Chinese Continental Science Drill program, this work concludes that compared to the AFT ages from surface outcrops, the low temperature thermochronological ages from the boreholes show a better relationship between age, elevation and closure temperature, and the age becomes younger with increasing depth. In addition, the exhumation history in the Jiaodong and adjacent areas can be divided into two distinct stages： a short, rapid tectonic exhumation （-100-95 Ma） and a long, slow exhumation since 95 Ma. The rate and amount of tectonic exhumation since 95 Ma are inferred as -30 m Ma-1 and -3 km, respectively.展开更多

文摘凡作史者,大约可分为两大类。第一类似可称为历史学者,他们的工作目的不是去发现历史对于现实的价值,而是像考古工作者从地下发掘历史一样,从浩瀚的文字、实物资料中去发掘历史,还历史本来面目;第二类可称为历史学家,他们的目的不只是再现历史,而是像一个思想家一样站在人类历史(或思想)的某一高度(蹩脚的历史学家则站在某一低地)来审视历史。《基督教思想史》(A History
