矿产资源资产化管理创新研究——以湖南省为例

改革开放以来,市场经济的发展迫切需要我国矿产资源管理体制进行改革和创新。借鉴矿产资源资产化管理的国际经验,创新性地提出湖南省矿产资源资产化管理的“321”模式：构建三级矿权,优化矿产资源产权安排;健全两级市场,优化矿产资源的配置机制;优化一级控管,完善矿产资源宏观调控和管理。希望能为湖南省及其他省市矿产资源管理体制的改革和创新提供参考借鉴。     

山西省矿产资源开发中的外部不经济问题浅析

矿产资源开发过程中存在严重的外部不经济问题,突出表现在环境污染和生态破坏.本文运用经济学理论,通过对矿产资源开发利用的经济行为分析,发现由于矿产资源和生态环境具有准公共物品的性质,容易产生"搭便车"和"公地悲剧",进而导致此类产品的供求失衡.解决外部性问题的主要途径是征收"庇古税"和产权界定.本文结合山西的具体情况,提出必须建立生态环境补偿机制,并提出了具体的政策建议.     

Economic Viability Among Post-Retirement Aged Women

Longer life expectancy has increased concern about living standards among elder women. This paper examines the relation between labor market status and living standard post-retirement. We use data from two national surveys to contrast economic circumstances of post-retirement aged and currently employed women. Financial resources of aged women and factors associated with their magnitude are identified. We examine current economic resources and employee benefits of women who will retire after the year 2000. The paper concludes with a discussion of proactive mid-life strategies for long-term economic stability among women, with emphasis on unique concerns, of black women.     

Gambling-related problems across life domains: an exploratory study of non-treatment-seeking weekly gamblers

This study uses content analysis to provide a qualitative exploration of how life roles are affected by frequent (i.e. at least weekly) gambling, based on in-depth interviews with a community sample of 161 non-treatment-seeking frequent gamblers. Over half (51.6%) of the participants indicated problems associated with gambling and 131 examples were identified. The majority of problems were relational (50.4%), followed by financial (19.8%), work (13.7%), and school related (8.4%). Slightly less than half of participants (41.7%) reported losses due to gambling and 92 examples were provided. The most frequently reported loss was identity related (54.3%), which included self-esteem/shame (38.0%), estrangement from family (34.0%), estrangement from friends (16.0%), and estrangement from work colleagues (6.0%). Additional losses included health (29.3%) and financial (8.7%). Almost two-thirds of participants (64.6%) reported difficulty concentrating in family (18.4%), work (16.8%), and school (9.6%) activities, whereas general concentration problems comprised an additional 48.8% of the examples provided. Half of participants (49.1%) discussed behavioral withdrawal due to gambling, which included withdrawal from work (44.3%), relationships (24.5%), school (15.1%), and personal (6.6%) activities. These findings paint a complex picture of how gambling interferes with different life roles for some frequent gamblers, identifying important areas for future research and practice.     

我国矿业权市场化的障碍

通过对中国矿业权市场发展现状进行分析 ,找出了中国矿业权市场化的障碍 :矿业权价值的不确定性、矿业权管理机构同时具有管理者与交易者两种身份、中央与地方两级政府管理权限与利益界定不清。根据分析结果 ,提出了中国矿业权市场化的解决办法。     

老年妇女骨质疏松性髋部骨折的危险性预测

目的探讨老年妇女骨质疏松性髋部骨折的危险性因素,建立判别方程,为预测老年妇女骨质疏松性髋部骨折提供依据.方法以髋部骨折老年女性患者及保健体检的老年妇女各30例为研究对象,分为观察组和对照组.测量所有样本髋部BMD(病例组为健侧,对照组为左侧)、颈干角(NSA)、左手握拳力;根据身高体重算出BMI;确定个人及家族女性骨折史.通过logistic回归分析及判别分析,进行统计学处理.结果老年妇女骨质疏松性髋部骨折的危险因素为:ward区BMD、NSA、BMI、左手握拳力;老年妇女骨质疏松性髋部骨折的危险性判别方程:Y1=-8.802×X1 88.803×X2 9.936×X3 8.119×X4 2.634×X5 22.439×X6-691.647,Y0=-9.901×X1 93.959×X2 15.872×X3 8.045×X4 3.037×X5 23.533×X6-696.284;将判别方程进行组内回代检验,特异度为76.7%,灵敏度为86.7%,预测正确率为81.7%.结论通过判别方程能够预测老年妇女骨质疏松性髋部骨折的危险性.     

对矿产资源可持续开发利用的思考

中国要实现全面建设小康社会和现代化建设的目标,不能走过度消耗自然资源特别是不可再生矿产资源的老路.必须立足于中国国情,落实科学发展观,切实转变经济增长方式,走新型工业化道路,矿产资源的可持续发展战略应当确立适度利用的对策,以促进和保证经济社会的可持续发展.     

论中蒙两国合作开发矿产资源的战略推进导向

蒙古国是中国实施睦邻、富邻、安邻基本政策的主要对象.从2008年6月访问蒙古国签署《中蒙经贸合作中期发展纲要》,到党的十八大做出统筹双边、多边、区域次区域开放合作战略部署,习近平主席一直关注着中蒙两国经贸合作,特别是在矿产资源务实合作方面的进程,并且表示今后将把矿产资源开发作为双边经贸合作重点来加大投入力度.有鉴于此,深入剖析两国合作开发的不利因素和有利条件,切实提出两国合作开发的推进对策意义重大.     

1.5m2高频振动筛结构改进

针对目前在矿棉板备浆生产线上广泛使用的高频振动筛存在的噪音大、动力消耗大、筛板易堵塞、除渣效果差等 问题,对高频振动筛筛框结构、筛板形状和减震弹簧等进行了优化改进,对振动频率、振幅、筛板的孔径通过理论计算得 出几个基本数值范围,再通过对基本数值范围内的不同数值的实际测试,确定最佳数值。新设计的振动筛经实际使用表 明运行稳定,浆料利用率高,能耗低,噪音小,取得了很好的经济效果。     

建立黄河三角洲生态补偿机制研究——以山东省东营市为例

在国内外,生态补偿机制已在农业、资源开发、河流治理等领域得到广泛实施,较好地解决了生态环境保护和建设问题。东营是黄河三角洲开发建设的主战场,生态环境存在较多问题,保护和建设资金匮乏,急需构建运行合理、兼顾多方效益的生态补偿机制。根据东营市的生态环境情况,应本着"谁破坏谁修复,谁受益谁补偿"的原则,重点在油气资源开发、湿地保护和林地建设等领域,依据合理的生态环境补偿标准进行生态补偿。可通过争取国家加大财政支持力度、以税费方式向破坏主体和受益主体征收、市场化融资等方式筹措补偿资金。
