人类能最终战胜“人口魔鬼”吗？

界定了两种"人口魔鬼"的概念,并简单回顾了人类与"人口魔鬼"斗争的历程.在今后几十年或者稍长的时间里,世界人口总数不会无限增殖下去,人类有望战胜"过剩人口魔鬼".但在达到人口顶峰后,由于人口持续缩减,人类的未来不太乐观.

国际税收情报交换与纳税人权利保护研究

在经济全球化的背景之下,作为国际税务合作的重要形式,国际税收情报交换制度越来越受到各国以及各国际组织的关注。在国际税收情报交换实施过程中的一大突出问题是对相关纳税人权利的漠视。在各相关国际法律文件中对税收情报交换中的纳税人权利保护作了一些规定。这些权利可以分为三个层次。实践中加强税收情报交换中纳税人权利的保护势在必行。     

Testing equality of variances in the analysis of repeated measurements

The problem of comparing the precisions of two instruments using repeated measurements can be cast as an extension of the Pitman-Morgan problem of testing equality of variances of a bivariate normal distribution. Hawkins (1981) decomposes the hypothesis of equal variances in this model into two subhypotheses for which simple tests exist. For the overall hypothesis he proposes to combine the tests of the subhypotheses using Fisher's method and empirically compares the component tests and their combination with the likelihood ratio test. In this paper an attempt is made to resolve some discrepancies and puzzling conclusions in Hawkins's study and to propose simple modifications.
The new tests are compared to the tests discussed by Hawkins and to each other both in terms of the finite sample power (estimated by Monte Carlo simulation) and theoretically in terms of asymptotic relative efficiencies.     

滇南荒田铅锌矿床地质特征及找矿标志

荒田铅矿矿床位于华南褶皱系、扬子准地台和唐古拉-昌都-兰坪-思茅褶皱系三大Ⅰ级构造单元衔接过渡部位,属红河断裂北侧的回新-虾洞-荒田-大冷山铅锌银多金属成矿带南东部。矿区主要出露下二叠统茅口组(P1m)、玄武岩组(P1β)、上三叠统火把冲组(T3h),为一套海相碳酸盐岩-基性火山喷发-沉积岩组合。铅锌矿体赋存于玄武质、灰质角砾岩中并受角砾岩性和厚度控制,富厚部位常在褶皱(背斜)的两翼和向斜的槽部。玄武质、灰质角砾岩层和次级褶皱的两翼、槽部是重要的找矿标志。矿床成因属"火山沉积-岩浆期后热液+后期构造改造富集"。     

中国服务业发展悖论——基于“两波”发展模式的研究

本文借鉴最新文献对服务业发展规律的测度方法,用中国1952—2010年的地区面板数据对我国服务业比重变化的长期规律和阶段性特征进行了测度,结果认为:宏观国家层面上,我国服务业比重的变化确实有悖于世界经济整体服务化的趋势;但在地区层面上,我国服务业比重与人均GDP的关系基本符合"服务业比重随经济发展不断上升"的普遍规律,所谓经济服务化的"中国悖论"在地区层面上并不存在;对服务业发展的阶段性特征和地区差异进行分析发现,我国大部分地区仍然处于以传统服务业为主的第一波发展阶段,只有少数地区进入了以现代服务业发展为主导的第二波。文章最后对我国服务业发展规律的成因进行了一般分析和实证检验。     

The management of acid-related disorders: the burden of disease and the need for effective treatment

Summary

A large and increasing number of people suffer from acid-related disorders such as dyspepsia, gastro-oesophageal reflux disease (GORD), and peptic ulcer disease. In 1994 alone, about 2 million patients consulted their family doctor for an acid-related disorder. Treatment of these patients represents a high cost to the NHS in terms of medications, consultations, referrals and treatment of complications. UK government statistics also indicate that there is a huge economic burden associated with acid-related disorders in terms of lost productivity.

Effective management of acid-related disorders is required to ensure that the available resources are used efficiently and to the benefit of the NHS, society and the patient.

Proton pump inhibitors are the most effective and predictable therapy available for acid-related disorders and many clinical studies have demonstrated their superior efficacy over H2-receptor antagonists in the management of these conditions. These therapeutic advantages translate into economic gains. Several economic studies have shown that it is more cost-effective to treat GORD and peptic ulcer disease with the proton pump inhibitor omeprazole than with H2-receptor antagonists.
