This article examines how role theory can enhance the middle-power literature in understanding the role preferences of middle powers. Rather than treating it as merely a function of material capability or good international citizenship, this article resituates middle power as a concept of international status that states aim to pursue through the enactment of role conceptions. Thus, it reinstates a conceptual distinction between ‘middle-power status’ and ‘middle-power roles’. The article suggests that the notion of role conceptions can analytically connect the status-seeking behaviour of middle powers with their foreign policy agenda. In so doing, it provides a more nuanced explanation of middle-power behaviour, which might differ between one middle power and another. Using Indonesia and South Korea as case studies of middle power, this article contends that foreign policymakers have strategically conceptualised and enacted several main roles that aim to capture historical experience, as well as ego and alter expectations, in order to pursue middle-power status. These role conceptions determine the foreign policy agenda of states in articulating their middle-power status.  相似文献

Archaeological surface finds are difficult to date. There are several useful methods, but each requires special circumstances and has one drawback or another. On the west coast of South Africa marine shell are abundant on surface sites but they are rarely dated because they are perceived to be in disturbed context and in questionable association with artefacts. This paper attempts to rectify this misconception and shows that, although far from perfect, a large suite of surface dates can shed as much light as excavated data. On the Vredenburg Peninsula they help refute the hypothesis that two economically and culturally distinct populations shared this pre-colonial landscape since 2000 BP.  相似文献

In South Africa, air photos were used in the 1960s and 1970s to plot distribution maps of pre-colonial stone-walled structures in order to study the peopling of this landscape. Different architectural styles of stone-walled structures were attributed to different cultures, who shared a mixed agricultural and pastoralist economic base and a cattle centered world-view. New technologies such as Google Earth satellite imagery as well as Geographic Information System software justify revisiting these structures as they facilitate more complex analyses of larger databases. The spatial analysis of remotely sensed settlement data from the Suikerbosrand Nature Reserve near Johannesburg shows significant changes in settlement patterns from dispersed homesteads to nucleated towns during the last two or three centuries before colonial times. These changes echo similar patterns reported in the neighboring North West Province, where they have been interpreted as a sequence of evolution in social, political and economic complexity. In the Suikerbosrand reserve climate change, conflict and other factors may have helped bring about the observed changes in settlement patterns.  相似文献

Dendrochronological methods can be applied to the reconstruction of different types of environmental events such as climate changes, fires, glacier movements, floods, earthquakes, volcano activity. In the field of geomorphology dendrochronology is increasingly frequently used for the absolute dating of different types of mass-movements (rock falls, landslides and debris flows, etc.). Trees growing on slopes transformed by mass-movements are tilted and wounded while their stems and root systems are exposed or buried under sediment. These events are recorded in wood anatomy as eccentric growth, reaction wood, scar overgrowth by callous tissue, changes in cell size or adventitious root production. Dating changes in wood anatomy allows to date and precisely reconstruct the spatial and temporal occurrence of mass-movements with at least one year resolution. The paper provides a review of existing dendrochronological tools used in geomorphology and also an example of the application of eccentric tree-growth to reconstruct landsliding. Using tree-ring eccentricity allows to (1) obtain a dynamic depiction of slopes, (2) study landslide activity, not only contemporary, but also in the last tens of hundreds of years (depending on the stand age).  相似文献

The Arab Spring has reshaped the Islamist landscape in the Middle East drastically. After decades of repression and exclusion, Islamist parties have taken power in Egypt, Tunis, and Morocco. However, the startling rise of Salafism (Salafiyya) remains the most visible feature of the new Islamist scene in the region. After decades of eschewing politics for theological and political reasons, Salafi movements and groups have rushed into electoral politics enthusiastically. They became keen to form political parties, contest elections, and vie for power. In Egypt, the Salafi parties fared well in the post‐revolution parliamentary elections and are a key player in drafting Egypt's new constitution. This article explores the rise of Salafism after Mubarak and examines its effects on the democratic transition in Egypt. It investigates the ideological and theological stance of Salafi movements and parties on politics and democracy in particular. The argument put forward is that the extraordinary political openness in Egypt after the revolution has pushed Salafis into everyday politics. Subsequently, Salafis have become more inclined to adopt a pragmatic and practical discourse. Based on field research, this article provides a thematic analysis of Egyptian Salafism and assesses its political future.  相似文献
