A new species of Eomeropidae (Insecta: Mecoptera) from the Middle Jurassic of China

The Eomeropidae is a species-poor family with only 11 known fossil species from the Early Jurassic to Palaeogene. A new species of fossil eomeropid, Tsuchingothauma gongi sp. nov., is described based on a well-preserved wing from the Middle Jurassic Daohugou deposits of Inner Mongolia, China. Our new species is distinguished from the type species T. shihi mainly in having very numerous crossveins and cells; more longitudinal veins: 13 and 11 terminal branches in radial sector and medial field, CuA with 3 terminal branches and A with 7 terminal branches.

The Necessity for Multi-disciplinary Research: Ralph Jacobi's Institute of Freshwater Studies

In spite of many proposals, Australia has no national freshwater research centre. Thus the passing in the Senate of Ralph Jacobi's private member's bill for an Institute of Freshwater Studies in 1982 was unusual. His driving force was the need to overcome State boundaries and for research to inform policy and management of water resources. It gained widespread support, and not just from the parliamentary Labor Party, but was strongly opposed by the Fraser government, State and federal water bureaucracies, and the Commonwealth Scientific and Industrial Research Organisation (CSIRO). The election of 1983 prevented further discussion in parliament, but the proposal was part of the Labor Party platform taken to the election. An Interim Council set up to investigate whether or not such an institute should be established, but with narrow terms of reference very different from those in Jacobi's bill, sided with the large water bureaucracies and CSIRO, in spite of majority support for an institute. An institute was rejected and the government accepted the recommendation. Jacobi's proposal failed primarily because of a fear of independent advice by many in the bureaucracies, a potential loss of power and influence, and inter-governmental rivalries. The status quo remained; the bigger picture is still unseen.

跨文化视野下孔子学院的管理与建议

孔子学院经过10年发展已取得了十分明显的成就,有效提高和改善了中文乃至中国的国际形象。与此同时,高速发展的背后也暴露出诸多问题。针对这些问题,在外部建设上需注重国内外舆论的导向作用、资金来源尽量多元化以及加强专业建设等;在内部管理上需加强财务行政管理、教学活动管理及健全评估管理系统。通过以上举措来提高孔子学院管理水平,加强其文化交流平台的作用。     

以科学发展观指导信息学院的发展

以科学发展观为指导．从高等教育的办学规律出发,对信息学院发展的目的、本质、内涵和模式进行了认真的分析和思考。认为要实现信息学院全面、协调、可持续的健康发展。就要实现学科建设、教学科研、管理工作、对外交流、思想政治工作等方面的协调发展;实现规模、质量、结构、效益的有机统一;实现以学生为本、以教师为本,促进人的全面发展。认为要有先进的办学理念,准确的办学定位,合理的发展规划和正确的舆论导向,从而在思想认识和宏观战略层面上全面落实科学发展观;要认真分析教学、科研、管理、改革、思想工作等业务领域的实际情况,并正确处理他们之间的相互关系,寻找学院不同阶段的工作切入点。从而在办学实践和具体工作层面上全面落实科学发展观。

Forty‐Nine Major and Trace Element Concentrations Measured in Soil Reference Materials NIST SRM 2586, 2587, 2709a, 2710a and 2711a Using ICP‐MS and Wavelength Dispersive‐XRF

Excellent agreement was noted in the concentration of major and trace elements in five NIST (National Institute for Science and Technology) soil reference materials (NIST SRM 2586, 2587, 2709a, 2710a and 2711a) between measurement results from wavelength dispersive‐XRF and ICP‐MS from two independent laboratories, and NIST certificate of analysis and literature data. We describe the variability in concentrations of up to forty‐nine elements (plus loss on ignition) and provide values for up to twenty‐one elements previously uncharacterised by NIST in these soil RMs. The additional characterisation provided in this investigation can be utilised to reduce the measurement bias of custom calibration routines and improve the quality of control checks developed using these NIST RMs.     

Evidence for coelacanths in the Late Triassic (Rhaetian) of England

The right gular plate of an indeterminate coelacanth from the Westbury Formation (Upper Triassic, Rhaetian) of Blue Anchor Point, Somerset, southwest England is reported. This occurrence represents the first convincing evidence of coelacanths from the Triassic of the United Kingdom. The new specimen suggests a fish of approximately 0.61 m length.     

用混合源模型研究矿山地震震源机制

本文讨论了矿山地震的混合源机制问题，并根据内源矩张量分解的特点提出了一种较合理的点源混合机制以及拟合求解方法。这相当于利用Ｐ波初动振幅进行相对矩张量反演，对于区分双力偶事件和非双力偶事件是有意义的。在简化情况下，对１９８７年发生在门头沟煤矿的１５次事件进行了讨论，发现它们大多属于剪切事件。
