ABSTRACT

Natural resource-based conflicts continue to occur in different parts of Nigeria with negative implications. This study investigated the phenomena of natural resource conflicts vis-à-vis their propensities to impact political economy and national security negatively. Data for the study were sourced from theoretical and empirical evidence. Empirical data were sourced from existing studies selected on the basis on their relevance to the study and analysed based on their content. The limitation to this approach is the obsolete and subjective nature of some the literature. This limitation was, however, addressed among others through the author’s knowledge of the issues under study. The study found that Nigeria is enmeshed in conflict over ownership, distribution, access to or competition over natural resources such as petroleum resources and agricultural land and these conflicts have undermined democracy, human rights, the economy and the nation’s security. The paper identified poor resource governance, environmental factors and poor political leadership as the causes and drivers of these conflicts. It recommends natural resource governance among others, as a way out of the problem.     

Conflict and third-party intervention

The paper looks at various scenarios of possible concern for intervening third parties when two factions are engaged in a conflict and act strategically against one another. A standard conflict model is used to determine appropriate intervention strategies in order to lower the overall level of conflict. Choosing a suitable strategy in such a setting, the third party must not only take into account the direct impact of its efforts but also the indirect impacts that result from the strategic interaction among the parties involved.     

Transnational terrorism as a spillover of domestic disputes in other countries

This paper models transnational terrorism as a three‐way strategic interaction involving a government that faces armed opposition at home, which may spill over in the form of acts of terrorism by the state's opponents against the government's external sponsor. The external sponsor also utilises deterrence against potential terrorists, which only lowers terrorism if terrorists are not intrinsically motivated by a deep‐seated sense of humiliation. The model highlights the importance of intrinsic motivation. A rise in the external power's preference for deterrence against terrorism may backfire in these circumstances. Increases in the government's military efficiency against the rebels, who are also terrorists against the government's sponsor, raises overall levels of violence.     

ON ETHNIC CONFLICT AND THE ORIGINS OF TRANSNATIONAL TERRORISM

Using the ITERATE dataset, we explore the origins of transnational terrorist activity, from 1982 through 1997, in 118 countries. We model terrorism, not as a function of a nation’s ethnic, religious or linguistic fractionalization, but as an independent measure of perceived ethnic tensions. When we control for institutional quality, evidence that political rights and civil liberties mitigate the terrorism‐producing effects of ethnic tensions exists only since 1990. Economic freedoms, on the other hand, robustly reduce the number of terrorist attacks originating in ethnically tense societies.     

STRATEGIC DEFENSE AND ATTACK FOR SERIES AND PARALLEL RELIABILITY SYSTEMS: COMMENT

The contest-theoretic literature on the attack and defense of networks of targets focuses primarily on pure-strategy Nash equilibria. Hausken's 2008 European Journal of Operational Research article typifies this approach, and many of the models in this literature either build upon this model or utilize similar techniques. We show that Hausken's characterization of Nash equilibrium is invalid for much of the parameter space examined and provides necessary conditions for his solution to hold. The complete characterization of mixed-strategy equilibria remains an open problem, although there exist solutions in the literature for special prominent cases.     

Asymmetry of Values,Indigenous Forces,and Incumbent Success in Counterinsurgency: Evidence from Chechnya

This article fills the gap in existing scholarship on asymmetric conflict, indigenous forces, and how socio-cultural codes shape the dynamics and outcomes of conflict transformation. Specifically, it identifies three key socio-cultural values commonplace in honorific societies: retaliation, hospitality, and silence. As sources of effective pro-insurgent violent mobilisation and support from among the local population, these values provide insurgents with an asymmetric advantage over much stronger incumbents. Using the case studies of the two Russian counterinsurgencies in Chechnya, the article shows the mechanisms on the ground through which Moscow’s deployment of indigenous forces against insurgents helped to stem the tide of conflict, reversing the insurgents’ initial advantage in terms of asymmetry of values.     

二语熟练度及语言使用特征对双语者抑制控制能力的影响

本文考察双语者二语熟练程度及不同语言使用特征对其抑制控制能力影响的差异。根据二语的熟练程度将被试分为熟练双语者组和不熟练双语者组,在熟练组和不熟练组中根据不同的语言使用特征划分为以口语为主和以阅读为主的两个被试组。所有被试都参与Stroop任务、Simon任务和Flanker任务。结果发现:熟练度高的双语者在三种任务中均表现出了优势反应。说明二语熟练程度对双语者的抑制控制能力有着促进作用;在不同语言使用特征组中,两组被试在simon任务与stroop任务中表现无显著差异,但表现出明显的CA效应。表明二语熟练度影响双语者的抑制控制能力;语言使用特征的不同对双语者的抑制控制能力无显著影响。     

Community preferences,insurgency, and the success of reconstruction spending

Existing theory on counterinsurgency does not adequately explain persistent insurrection in face of the reconstruction work currently underway in Afghanistan and Iraq. We starkly depart from the literature by developing a simple model of reconstruction allowing misalignment of occupier spending with community preferences. Insurgency arises endogenously as a result of the mix of spending rather than its level. Occupier insistence on its preferred path of reconstruction may lead to fewer projects of any kind being completed. In equilibrium, the occupier may accept an endogenous insurgency to achieve a preferred project mix, or be constrained in its choice even when no insurgency occurs.     

Business and peace in the Niger Delta: what we know and what we need to know

The global restructuring of state–society relationships driven by neoliberal logic has not only allowed for the taming of the ‘state’, which has paradoxically accentuated its inadequacies, but has also facilitated, for better or for worse, the emergence of business – especially transnational corporations – as a major political force in global governance. Consequently, while the issues of peace and conflict have traditionally been the concern of governments, businesses are now increasingly being expected to make peace and conflict their concern. However, despite claims and counterclaims that businesses can be moneymakers and peacemakers, analyses of the relationship between business and peace remain largely embryonic. This paper seeks to contribute to this emerging business and peace debate by drawing on insights from the Niger Delta conflict to ascertain what we know and what we need to know if businesses are to become peacemakers in conflict zones in Africa.     

基于DSm理论的雷达目标综合识别算法

针对数字多功能雷达的目标识别问题,提出了基于DSm理论的综合识别算法。将不同类型的识别结果置于统一的辨识框架中,并利用经典DSm组合规则进行信息组合,采用冲突按比例重分配规则重新分配组合结果,应用基于广义基本信任分配的决策规则进行判决。仿真结果表明,该方法避免了层次化识别结构带来的信息损失,识别结果中含有更丰富的目标信息。
