市场类矿产资源储量评审管理改革工作建议

随着矿业投资主体的多元化及市场化的不断深入,当前矿产资源评审制度已不能完全适应新形势下的市场环境,为解决新形势下市场对矿产资源储量评审需求与现有资源储量评审机制以及评审流程的矛盾,应正确处理政府和市场的关系,完善市场类矿产资源储量评审的运行机制,充分激活矿业市场要素。文章对现行矿产资源储量评审相关政策、法规、制度、部门规章以及市场的新需求进行了细致的研究,对目前现行评审制度中存在的问题进行了详细的剖析,提出了修订矿产资源储量评审备案文件的相关条款的建议,给出了建立市场化、现代化具有国际竞争力的矿产资源储量评审评价机构的路径设想,明确了市场类矿产资源储量评审评价的主要范围。

一个无可信第三方的自组织群体中匿名表决方案

在一个自组织群体中,成员之间是平等的关系,没有管理者或可信的第三方,典型的网络环境如移动Ad hoc网.给出了这种环境下匿名表决的形式化模型和安全定义,提出了一个具体方案, 基于RSA假设和离散对数困难性假设,在此安全定义下证明了方案的安全性.该方案允许参与者对某问题匿名表决,安全地计算表决结果,参与者之间也不需要任何交互,而且表决协议很容易转换为一个匿名的门限签名方案,在Ad hoc网中保护用户的隐私.     

Organizational software piracy: an empirical assessment

Application of Information Technology (IT) has had a significant impact on all aspects of business. Due to technology, the ease with which software can be pirated is increasing and is leading to increased concern for copyright protection. This paper reviews and discusses software piracy issues from a global perspective and reports the findings of a survey concerning the impact of sectors like government, private and academic in Turkey. Although software piracy has long been attracting the interest of academics, no quantitative research has ever been realized in this field in the country. Elsewhere also, most of the software piracy-related studies are from individuals' perspectives and are limited to students, academics, cost, and attitudes. Very few have reported findings related to IT professionals and organizations. The survey was conducted among IT managers of large-scale organizations from different sectors such as the government, private and academic community. Based on the survey of 162 IT managers, the results indicated that sectors have significant impact on software piracy to some extent.

A Different Race: The Philosophy

The infrastructure of a nation is the foundation of the nation's ability to compete in world markets, maintain a credible deterrence, influence other nations, and create surpluses for use in social programs. Part of the infrastructure that a nation will depend on economically and militarily in the 21st century will be located in space. Space, besides being an economic, technical, and strategic opportunity for various companies and countries, can also be a way to use engineering and technology to improve the condition of the human race. This paper explains a strategy for reprogramming money from the development and deployment of strategic offensive weapons and their delivery systems to developing the facilities and capabilities needed for nations to be active participants in the exploration and industrialization of space. The creation of the infrastructure needed to pioneer the space frontier will require all engineering professions, especially civil engineering, to stretch and reach for the stars.     

Findings of the second international conference on energy use management—ICEUM-II

It is evident that future worldwide patterns of energy use will be modifications of current ones. The objective of this work is to understand the directions these modifications are taking and to assess opportunities for bringing about beneficial changes and avoiding detrimental ones.

The future will see greater deficits of conventional fuels such as oil and gas and the certainty of higher prices. Fuel and electricity prices, already at record highs, are seen to double again in the next 1–2 years. As a consequence of potential scarcity, disruption of supplies and economic pressures, the danger of a major war is greater now than it has been in the past several decades. The problem is compounded by the fact that the public, in general, is not convinced there is a serious problem and is not prepared to take decisive action.

The United States—the world's major energy user—plays a pivotal role. The consequences of an ineffective U.S. national energy policy have been that U.S. imports remain high, oil prices stay high, the world economy is less stable and less oil is available for other nations. Commensurately, increased prices for food, industrial products, and transportation are resulting.

At this time, changing energy futures is less a problem of technology and more a problem of motivation, values and social awareness. New technology is available for many industrial processes, for heating and cooling buildings, for lighting and agriculture. New technology is urgently needed for energy efficient transportation. Unresolved are the issues of how best to educate and inform the public and to instill new values appropriate for the future. The public, in general, still is not convinced that there is a serious problem and still is not prepared to take decisive actions.

New energy resources are widely sought as replacements for conventional ones, especially those which are imported. While these efforts will lead to varying degrees of success, energy use management has been established during the decade of the 1970s as an effective near-term ‘resource’. It is the most immediate, least risky, cheapest and least environmentally damaging of all the potential options for solving energy problems. National and international policies must be modified to vastly increase the priority given this resource.
