We contribute to the lack of tools to support efficient industrial policy-making, especially in the mineral beneficiation policy literature. To address this vacuum, we adapt the product space analysis approach to incorporate an input-output value chain lens. This framework is applied to the case of steel in South Africa to derive novel insights regarding the (in)efficiency of implementing a downstream linkage-based beneficiation policy. Our dynamic analysis approach allows for interactions with the rest of the product space. We find that a ‘leap-frogging’ approach to development within the value chain may be more optimal than a strict beneficiation based industrial policy.  相似文献

This article examines the changing image of war in international law and politics. In classical international law, the ideal typical image of war was a duel between equal states, represented as 'magni homines', This conception of war was based on a particular reading of the sovereign equality of states and a corresponding interpretation of the enemy in war. Due to the attempts to outlaw war and the growing enthusiasm for the use of force in the name of humanity, this image of war has changed significantly. In current international relations, the use of force is increasingly defined as enforcement or a preventive action against wrong-doers, risks to international peace and security or against 'rogues'. This article examines the changing conceptions of sovereignty and war as well as the changing image of the international community that underlie this changing conceptualisation of the enemy.  相似文献

The Principality of Liechtenstein challenges the prevailing view in political science that ‘small is democratic.’ Located in the heart of Western Europe, the Principality is ruled by a monarch with extensive political powers. The present article examines how the smallness of the Principality contributes to the maintenance of powerful traditional leadership, and which strategies are used to legitimize the Liechtensteiner system vis‐à‐vis its population. On the basis of interviews with Liechtensteiner respondents, it is found that the smallness of Liechtenstein contributes to the position of the monarchy due to (1) the lack of alternative sources of identification, (2) the perception of the Prince as a neutral arbiter standing above the quarreling political factions, and (3) the dominant cultural code that limits citizens' opportunities to criticize the monarchy. The article highlights several ways in which the Prince has sought to legitimize his own position, and to undercut the criticism against him.  相似文献

Retinal hemosiderin deposition is a histologic indicator of sustained hemorrhage but cannot be used to precisely estimate the elapsed time since an episode of trauma. A 5‐month‐old male infant was admitted to hospital after acute deterioration. Examination revealed encephalopathy, subdural hematomas, and retinal hemorrhages consistent with abusive head trauma (AHT). At the age of 3, he was readmitted to hospital with spontaneous osteopenic fracture of the right femur. The patient deteriorated and died after unsuccessful resuscitation. Ophthalmopathological investigation showed atrophy of the retina and optic nerve and hemosiderin deposition in both eyes. Retinal hemosiderin deposition is currently generally assumed to disappear within 6–8 weeks after the occurrence of hemorrhage in AHT. This case report describes an infant with bilateral retinal hemosiderin depositions due to hemorrhages sustained from AHT occurring 32 months prior to death. Implications of this finding for the interpretation of retinal hemosiderin depositions in AHT are discussed.  相似文献
