From adversity to prosperity

This article interrogates the continuing relevance of the contractarian governance paradigm to resource governance and the impact of exploitation on the local population and environment in the Democratic Republic of Congo (DRC), Zimbabwe and Ghana. It highlights the susceptibilities of their governance processes, particularly the roles of the elites of the host communities, the multinational corporations, and the governing authorities in appropriating resources for their personal interests, resulting in tensions and conflicts. This scenario is borne out of inept leadership, as well as the defective and compromised administrative mechanisms operational in these countries. In view of this, the article underscores the need for a ‘new governance management paradigm’ anchored on a communitarian framework, which incorporates all stakeholders, to guarantee sustainable peace and prosperity, particularly in conflict zones. The article therefore concludes that achieving a nexus between forestry, mining activities and economic development in these countries will require a restructuring of the existing governance mechanisms; and advocates for a new governance model capable of curbing the excesses of local and foreign hegemony, including a total overhaul of the seemingly compromised supervising authority.     

“Disarmament Market” Effects of Information Disclosures

In yet another wave of discussion on nuclear disarmament among political scientists and practitioners, one of the topical issues concerns the problem of transparency, its mechanisms, costs, and benefits. Numerous—though often abstract—calls for greater transparency of nuclear arsenals and postures when promoting the idea of nuclear disarmament, however, do not give a clear rationale for states possessing nuclear weapons to pursue greater transparency. Meanwhile, many other research fields—such as economics and psychology—attempt to address problems related to the lack of exact information on the counterpart's activities and intentions. Economics offers one probable analog for the transparency problem: the issue of information asymmetry and its consequences. This article is an attempt to apply the classical model of a market with information asymmetry to the analysis of the transparency problem within the nuclear disarmament process. Such an approach could help pave the way for closer cooperation between economic and political scientists in the nuclear disarmament field.     

基于Stateflow的排队系统仿真方法

论述了排队系统与Stateflow相关概念,利用有限状态机理论与面向对象编程思想,提出了建立基于Stateflow排队系统模型的分析步骤,阐述了应用Stateflow对排队系统进行建模与仿真的方法,使用Stateflow对M／M／1／∞／∞／FIFO类型排队系统进行了具体的建模与仿真。仿真结果表明,基于Stateflow的模型与仿真能够有效地描述排队系统的统计特性,并具有可视化、流程化和层次化的特点。     

语用预设与图式理论

本文将语用预设与图式理论作对比性介绍与分析,探讨了它们在话语分析中的作用,通过明示的语项,激活相关的图式。经过演绎推理过程从百科图式知识中选择、获取最佳假设,从而恢复或再现语用预设含义,推导说话者真正的意图,达到对话语或语篇的理解。两个理论在语言学话语分析中的运用直接回答了“为什么有些事实在话语中被省略而可以被理解,并可以再现”的问题。

New results on a Ruckle problem in discrete games of ambush

This article deals with a two‐person zero‐sum game in which player I chooses in integer interval [1, N] two integer intervals consisting of p and q points where p + q < N, and player II chooses an integer point in [1, N]. The payoff to player I equals 1 if the point chosen by player II is at least in one of the intervals chosen by player II and 0 otherwise. This paper complements the results obtained by Ruckle, Baston and Bostock, Lee, Garnaev, and Zoroa, Zoroa and Fernández‐Sáez. © 2001 John Wiley & Sons, Inc.

契合新疆少数民族大学生特点的思政理论教学探析

由于受地域、民族、文化、宗教等因素的影响,新疆少数民族大学生的成长和发展具有特殊性,表现出民族特性鲜明、深受伊斯兰教影响、民族意识强烈、思想单纯、文化素质参差不齐等特点。新疆高校思政理论课教学存在着教学内容、课程组织针对性不强,教学方法僵化、手段单一等问题。只有充分挖掘新疆少数民族文化中的德育资源,贴近生活、深入浅出,完善考核机制、以学生为主体开展研究性教学,增进各民族大学生沟通交流,才能切实提高思政理论课教学的实效性,让学生内心认同、真心信服。     

基于变步长LMS的谐波电流检测方法的研究
