论突发环境事件的几个理论问题

突发环境事件在我国频频发生,且有愈演愈烈之趋势。应对突发环境事件,我们要建立完善的突发环境事件应急机制,力图在危机发生之虞,能有效的动员各类社会资源,防患于未然,努力将突发环境事件带来的危害降至最低。因此,文章将着重讨论突发环境事件的概念、突发环境事件应急机制的属性、应急机制等几个问题。     

福建外贸企业实现可持续发展的转型方向

当前福建省外贸环境正发生深刻的变化，外贸企业以往的商业模式、运营策略、市场定位都要发生战略性的调整。如何选择正确的转型方向，实现可持续发展，显得尤为重要。本文根据波特的“价值链”理论阐述了企业实现可持续发展的转型方向，并以香港利丰公司、厦门国贸集团等资料为例，对理论做了进一步的阐述与加强。

长三角近海海洋环境管理立法研究

长江三角洲经济区海洋经济发展势头强劲，但同时其近海也饱受海水水质恶化、赤潮灾害频发、海洋生态非健康等环境问题的困扰。长三角近海环境问题的解决需要一种特殊的环境管理方式，即区域海洋环境管理，这是海洋环境管理理论不断发展创新的成果，可以起到解决自然区域与行政区划之间的矛盾、协调多方利益和中观管理的有益补充作用。本文拟探讨通过贯彻区域海洋环境管理理念，创设适用于长三角毗邻海域的、针对海洋环境管理的区域性法律文件，来治理与维护这一海洋区域的环境，从而为其海洋经济发展创造有利条件，提供良好的环境依托，使发展走上可持续的道路。

独立的环境法益的刑法保护

本文随着独立的环境法益的提出 ,首先 ,从法哲学的角度对我国的环境刑法未充分重视独立的环境法益的保护进行了价值分析 ,并认为应当赋予自然环境以人格的权利。其次 ,从犯罪学和刑法学的角度对独立的环境法益的刑法保护密切相关的行政从属性理论进行了评判 ,认为只有突破功利的价值观和绝对的行政从属性 ,才能反映环境要素的固有存在 ,才是公正的环境刑法。最后 ,在以上前提下对我国环境刑法在独立的环境法益的刑法保护方面进行了新的论证。     

An affine‐invariant multivariate sign test for cluster correlated data

The author presents a multivariate location model for cluster correlated observations. He proposes an affine‐invariant multivariate sign statistic for testing the value of the location parameter. His statistic is an adaptation of that proposed by Randles (2000). The author shows, under very mild conditions, that his test statistic is asymptotically distributed as a chi‐squared random variable under the null hypothesis. In particular, the test can be used for skewed populations. In the context of a general multivariate normal model, the author obtains values of his test's Pitman asymptotic efficiency relative to another test based on the overall average. He shows that there is an improvement in the relative performance of the new test as soon as intra‐cluster correlation is present Even in the univariate case, the new test can be very competitive for Gaussian data. Furthermore, the statistic is easy to compute, even for large dimensional data. The author shows through simulations that his test performs well compared to the average‐based test. He illustrates its use with real data.     

A partial score test for difference among heterogeneous populations

In event time data analysis, comparisons between distributions are made by the logrank test. When the data appear to contain crossing hazards phenomena, nonparametric weighted logrank statistics are usually suggested to accommodate different-weighted functions to increase the power. However, the gain in power by imposing different weights has its limits since differences before and after the crossing point may balance each other out. In contrast to the weighted logrank tests, we propose a score-type statistic based on the semiparametric-, heteroscedastic-hazards regression model of Hsieh [2001. On heteroscedastic hazards regression models: theory and application. J. Roy. Statist. Soc. Ser. B 63, 63–79.], by which the nonproportionality is explicitly modeled. Our score test is based on estimating functions derived from partial likelihood under the heteroscedastic model considered herein. Simulation results show the benefit of modeling the heteroscedasticity and power of the proposed test to two classes of weighted logrank tests (including Fleming–Harrington's test and Moreau's locally most powerful test), a Renyi-type test, and the Breslow's test for acceleration. We also demonstrate the application of this test by analyzing actual data in clinical trials.
