Urban Depression Patients Should Receive Public Attention

正In China,although some celebrities like Leslie Cheung and Yang Kun openly disclosed their symptoms of depression and many people have heard about depression,few people really understand and pay attention to depression.Not long ago,the famous American comedian Robin Williams committed suicide due to depression,which upset many people.However,generally,people still believe that depression is only a"mood disorder",and     

A distribution-free approach to inducing rank correlation among input variables

A method for inducing a desired rank correlation matrix on a multivariate input random variable for use in a simulation study is introduced in this paper. This method is simple to use, is distribution free, preserves the exact form of the marginal distributions on the input variables, and may be used with any type of sampling scheme for which correlation of input variables is a meaningful concept. A Monte Carlo study provides an estimate of the bias and variability associated with the method. Input variables used in a model for study of geologic disposal of radioactive waste provide an example of the usefulness of this procedure. A textbook example shows how the output may be affected by the method presented in this paper.     

死刑的立法技术特征

中国是世界上死刑罪名最多的国家之一.然而,限制或废除死刑,早已是世界性的刑事立法趋势.就法学知识而言,死刑存废问题已被刑法哲学和犯罪学所穷尽;中国的死刑限制论和废止论对刑事立法也并未产生实效.死刑的学术研究已步入僵局.单纯研究死刑的立法技术特征,尚不为学界所充分重视.事实上,中国的死刑立法技术特征十分明显.研究死刑的立法技术特征,可以开拓学术研究视域,深入探知立法精神,为改善立法建言献策.     

The Complementary Roles of Mitigation and Insurance in Managing Catastrophic Risks

This paper examines the impact that insurance coupled with specific risk mitigation measures (RMMs) could have on reducing losses from hurricanes and earthquakes as well as improving the solvency position of insurers who provide coverage against these hazards. We first explore why relatively few individuals adopt cost-effective RMMs by reporting on the results of empirical studies and controlled laboratory studies. We then investigate the impact that an RMM has on both the expected losses and those from a worst case scenario in two model cities—Oakland (an earthquake-prone area) and Miami/Dade County (a hurricane-prone area) which were constructed respectively with the assistance of two modeling firms. The paper then explores three programs for forging a meaningful public-private sector partnership: well-enforced building codes, insurance premium reductions linked with long-term loans, and lower deductibles on insurance policies tied to mitigation. We conclude by briefly examining four issues for future research on linking mitigation with insurance.     

A-CDMA系统多址与保密结合的扩频码的研究(英文)

基于一个异步直接序列码分多址模型,给出了多址与保密结合的扩频码应具备的条件。为了研究这类扩频码对A-CDMA系统性能的影响,比较了纯随机序列和Gold伪随序列的偶互相关概率分布,得到一些有用结论。
