Economic prosperity of the gold-mining industry in Australia and the consequent gold tax

Income from gold mining in Australia was declared tax-exempt in 1924. This tax-exempt status was removed and tax on income from gold mining was imposed in 1988 with effect from 1 January 1991. This paper documents the political process that led to the imposition of this tax. It provides evidence that rapid prosperity of the Australian gold-mining industry in the 1980s led to increased political sensitivity and removal of the industry's tax-exempt status of nearly seven decades.     

矿山企业在社区建设中的社会责任

矿山企业,离不开社区民众的支持、容忍和默契,与所在社区民众是一种相互依存的社会关系;不只是矿业社区建设的消费者,更不是旁观者,而是社区建设的主要责任者。矿山企业不能将市场行为带入社区生活而损害社区民众的既有权益,必须承担维护社区建设的社会责任;社区中的"矿山企业公民"角色,应将经济人自利理性转换为社会人利他理性,成为社区民众的好伙伴、好邻居,承担推进矿业社区建设的社会责任。矿业企业在矿业社区建设中必须和应当承担的社会责任,既是挑战也是发展机遇。

层次分析法在湖北省黄金矿产企业核心竞争力评价中的应用研究

为了对黄金矿产企业等资源型企业的核心竞争力进行评价研究,并顺利完成湖北省科技攻关项目《湖北省黄金矿产企业核心竞争力评价研究》,经过对3家主要黄金矿产企业进行实地调查问卷,建立评价模型,选取评价指标等工作,文章采用层次权重决策分析方法――层次分析法(AHP)对黄金矿产企业的核心竞争力进行定量分析,并通过计算分析,求解出湖北省3家主要黄金矿产企业核心竞争力指标平均值。     

Systematic acceleration of radical discovery and innovation in science and technology

A systematic two-component approach (front-end component, back-end component) to bridging unconnected disciplines and accelerating potentially radical discovery and innovation (based wholly or partially on text mining procedures) is presented. The front-end component has similar objectives to those in the classical literature-based discovery (LBD) approach, although it is different mechanistically and operationally. The front-end component will systematically identify technical disciplines (and their associated leading experts) that are directly or indirectly-related to solving technical problems of high interest. The back-end component is actually a family of back-end techniques, only one of which shares the strictly literature-based analysis of the classical LBD approach. The non-LBD back-end techniques (literature-assisted discovery) make use of the human experts associated with the disparate literatures (disciplines) uncovered in the front-end to generate radical discovery and innovation.Specifically, in the literature-assisted discovery operational mode, these disparate discipline experts could be used as:

1. Recipients of solicitation announcements (BAA, SBIR, MURI, journal Special Issue calls for papers, etc.),

2. Participants in Workshops, Advisory Panels, Review Panels, Roadmaps, and War Games,

3. Points of Contact for Field Science Advisors, Foreign Field Offices, Program Officer site visits, and potential transitions.

基于网络数据挖掘的信息安全监控体系

网络在国民生产和生活中的逐步渗透对信息安全提出了严峻的挑战,应对此挑战的方法也只能通过对网络信息资源的监控来实现。本文将数据挖掘技术应用于网络信息安全监控,设计出一套基于网络数据挖掘的信息安全监控体系的概念模型。该体系通过多种方法对海量的网络数据进行收集,经过预处理后形成信息安全数据仓库,在此基础上进行数据挖掘,最终生成信息安全监控对象的特征信息和监控对象之间的关联信息,以达到对信息进行安全监控的目的。     

贵州省农村金融发展与农村经济增长关系的实证分析

本文以农村金融与经济增长相关理论为基础,阐述贵州省农村金融发展和经济增长现状,根据1978～2009年数据,通过协整检验说明贵州省农村金融发展农村经济增长之间存在长期均衡关系,并建立VAR模型来考察金融相关率变动与第一产业值之间的动态影响关系。实证分析表明,与经济增长速度相比,贵州省农村金融发展程度相对滞后,贵州农村经济增长对农村金融发展的影响要大于金融发展对经济增长的影响,农村金融发展对经济增长的促进作用不明显。     

基于改进的话题检测技术的TBT预警系统研究

目前的TBT预警研究，使用经济理论和数学模型分析产业数据进行预警，数据收集困难，时效性差。针对以上不足，本文首次将改进的话题检测技术应用于TBT预警，设计了基于改进的话题检测技术的TBT预警系统模型，将改进的话题检测技术成功应用于TBT预警研究。实验结果证明，改进的话题检测技术显著提高了话题检测的精确度。     

新疆人口居住状况及影响因素分析——新疆2005年1%人口抽样数据信息挖掘

本文依据新疆2005年1%人口抽样数据,运用数据挖掘技术,结合定性分析研究方法分析了新疆居民住房现状、结构与趋势。研究结果表明,新疆居民的居住条件有所改善,住房私有化程度提高,城乡之间和地区之间的居住条件差异较大,户主的收入、职业和受教育程度对家庭的住房条件有较大影响。最后对改善低收入群体的住房条件提出相应政策建议。     

Order without law? Property rights during the California gold rush

The paper reconsiders the nature of mining districts and property rights during the California gold rush. According to a widely accepted view advanced by Umbeck [Explorations in Economic History 14 (1977) 197; A Theory of Property Rights with Application to the California Gold Rush. Iowa State University Press, Ames, IA, 1981], in the absence of effective legal authority, district codes established secure property rights in mining claims. Such accounts neglect essential aspects of the economic context, specifically that the gold rush approximated an open-access race for a small number of high value deposits. We show that mining district codes gave equal attention to the rights of claim-jumpers as to claim holders, a balance that in practice generated chronic insecurity and litigation. A simple game-theoretic model illustrates stylized features of the situation.
