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. 相似文献

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. 相似文献

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。 相似文献

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.

This paper deals with a two‐person zero‐sum game called a search allocation game, where a searcher and a target participate, taking account of false contacts. The searcher distributes his search effort in a search space in order to detect the target. On the other hand, the target moves to avoid the searcher. As a payoff of the game, we take the cumulative amount of search effort weighted by the target distribution, which can be derived as an approximation of the detection probability of the target. The searcher's strategy is a plan of distributing search effort and the target's is a movement represented by a path or transition probability across the search space. In the search, there are false contacts caused by environmental noises, signal processing noises, or real objects resembling true targets. If they happen, the searcher must take some time for their investigation, which interrupts the search for a while. There have been few researches dealing with search games with false contacts. In this paper, we formulate the game into a mathematical programming problem to obtain its equilibrium point. © 2006 Wiley Periodicals, Inc. Naval Research Logistics, 2007 相似文献

This paper develops an inventory model that determines replenishment strategies for buyers facing situations in which sellers offer price‐discounting campaigns at random times as a way to drive sales or clear excess inventory. Specifically, the model deals with the inventory of a single item that is maintained to meet a constant demand over time. The item can be purchased at two different prices denoted high and low. We assume that the low price goes into effect at random points in time following an exponential distribution and lasts for a random length of time following another exponential distribution. We highlight a replenishment strategy that will lead to the lowest inventory holding and ordering costs possible. This strategy is to replenish inventory only when current levels are below a certain threshold when the low price is offered and the replenishment is to a higher order‐up‐to level than the one currently in use when inventory depletes to zero and the price is high. Our analysis provides new insight into the behavior of the optimal replenishment strategy in response to changes in the ratio of purchase prices together with changes in the ratio of the duration of a low‐price period to that of a high‐price period. © 2006 Wiley Periodicals, Inc.
