A new Geologic Time Scale, with special reference to Precambrian and Neogene

Episodes 2004年第2期27卷 83-100页

GeologicalSurveyofCanada 601BoothStr.OttawaOntarioK1AOE8Canada. FacultyofEarthSciences UtrechtUniversity3508TAUtrechtTheNetherlands.

A Geologic Time Scale (GTS2004) is presented that integrates currently available stratigraphic and geochronologic information. Key features of the new scale are outlined, how it was constructed, and how it can be further improved. The accompanying International Stratigraphic Chart, issued under auspices of the International Commission on Stratigraphy (ICS), shows the current chronostratigraphic scale and ages with estimates of uncertainty for all stage boundaries. Special reference is made to the Precambrian part of the time scale, which is coming of age in terms of detail, and to the Neogene portion, which has attained an ultra-high-precision absolute-age calibration.

A Cross-Cultural Comparison of the Issue of Self-Knowledge in Sophocles＇ Oedipus Tyrannus, Shakespeare＇s hamlet and the Bhagavadgita

引用

Journal of Philosophy Study 2012年第7期2卷 439-449页

作者： lourens Minnema VU University

Greek and Shakespearean tragic truth emerges from pollution, moral brokenness, and pain. This also applies to the tragic truth of the Indian epics, except that this karmic kind of truth is not considered decisive. Crucial in the Indian case is cosmic truth, and hindu cosmic truth is never produced out of pollution or pain. In Arjuna＇s case, Krishna＇s revelatory knowledge is religiously saving knowledge, whereas in Oedipus＇ case, Apollo＇s and Teiresias＇ revelatory knowledge is religiously dooming knowledge. In hamlet＇s case, religiously saving knowledge is an object of theological speculation and of philosophical doubt. In the hindu case, self-knowledge means absolute knowledge and ultimate liberation; in the Greek case, self-knowledge means self-discovery and the recognition of human fragility; in the Shakespearean case, self-knowledge means self-exploration and doubting oneself.

介绍新近纪海相生物地层研究的新进展。2004年新的"国际地质年代表"以405ka偏心率长周期为基础来划分新近纪的主要地层界线,标志着轨道地层学时代的到来。新生代包括E1—E162偏心率长周期,底界的年龄为65.5±0.3Ma,其中新近纪有E1—E58周期,底界年龄为23.03Ma,并且根据天文调谐得出一系列新的古地磁年龄和生物事件年龄。由于这些新年龄,特别是接近新近纪底部的年龄与早期结果相差0.5Ma或更大,所以将其汇总介绍,以求与当前国际研究保持同步衔接,增强海洋新近纪高分辨率地层工作的准确性。

对四川文理学院8名外教自我适应性调整情况进行4个学期跟踪访谈定的定性研究,发现:8名四川文理学院外籍教师自适应效果来看,心理和生理调整的效果比较明显,效果比较好;相比较而言,在社会关系、文化和生活方式层面的调整效果较差。高校外籍教师管理部门要采取成立专门心理咨询机构、开设外籍教师沟通渠道、建立外籍教师与中国教师共同参与的社群组织等等措施帮助他们解决难以自我调整的这些问题。
