This essay explores the post-World War Two anti-colonial Maasina Rule in north Malaita, Solomon Islands, to show how a church leader Shem Irofa'alu decided to establish a religious movement independent of the state and the traditional evangelical church. Irofa'alu's movement indexes an important moment of culture change towards increasing enthusiasm for the often-overlooked Christianity-based forms of sovereignty in the region. It highlights that Maasina Rule was not only a powerful rupture in social processes, but also sharpened the growing division between state and church. Irofa'alu's role in Maasina Rule shows that his influence peaked between 1948 and 1950 and then went into rapid decline. This change in fortune coincided with a critical turning point in the colonial government's attempts to end the movement through appeasement. No longer the head of the evangelical church in Malu'u sub-district and frustrated about the mother church's governance, Irofa'alu retreated to his home area and set about establishing a new church, Boboa (‘Foundation’), his first attempt at organizing a self-governing assembly before introducing Jehovah's Witnesses in north Malaita. In later years, Irofa'alu became a prophet-exemplar for new generations of religious leaders trying to establish Malaitan sovereignties based on their own power to move the truth of prophecies away from foreign state and church organizations.  相似文献

The article explores the role of state-owned enterprises (SOEs) in the globalisation of China's infrastructure capital. Examining how accumulation strategies of Chinese SOEs are driven by a complex set of political and economic, state and private, interests, it foregrounds the inherently hybrid nature of China's state capitalism. We use Kenya's Standard Gauge Railway (SGR) as a case study to analyse how state infrastructure capital traverses borders, and the specific ways that contradictions of accumulation in China are relocated through the improvised hybridity of SOEs. In Kenya, China Road and Bridge Corporation, the main SGR contractor, shifted and adapted its strategies as the pursuit of economic productivity gave way to political priorities in China, simultaneously responding to changing socio-political circumstances in Kenya and across East Africa. Analysing these dynamics, we highlight the contingencies of, and limitations to, structural reorganisation of actually existing forms of state capitalism in China and beyond.  相似文献

South Africa has a coal-based energy system and extractive economy, largely responsible for its high emission levels relative to countries with similar GDP. This extractive, coal-based economy began during British colonisation and today shows few signs of transitioning rapidly to limit climate change. This paper interrogates the role of coloniality in climate delay, given that colonisation is responsible for establishing fossil fuel dependence in South Africa. Combining theory on decolonisation, specifically colonial hierarchies of power, with a critical discourse analysis, this research uses interview and policy data to show how colonial power hierarchies can lead to climate delay in South Africa, through normalising emissions intensive development and silencing alternatives. In doing so, it highlights the need to recognise the colonial foundations of climate change and the potential for a coalition between decolonisation and climate action to motivate for radical change both in South Africa and at a global level.  相似文献

This paper expands on the Narrative Policy Framework (NPF) by adding a theoretical and empirical exploration into macrolevel narratives. Existing NPF research largely neglects macrolevel narratives, which prevents the NPF from developing its full power. The main contributions of this paper are threefold: (1) It provides a definition of macrolevel narratives by conceptualizing them as the “story form” of a policy paradigm. (2) It proposes a model and an empirical approach, which may lay the foundation for a standard macrolevel NPF approach. (3) It contributes to the NPF's aim of connecting the macro and meso level. The paper tests the model in a comparative multi-method design applied to the Swiss child and adult protection policy. The findings show that macrolevel NPF analysis helps understand where mesolevel policy debates come from, namely from an underlying paradigm and its effects on institutions and culture that enable and constrain macrolevel narratives.  相似文献

In Westminster systems, governments enjoy a privileged position in the lawmaking process that they can use to deliver on their campaign promises and achieve their policy goals. What policy areas do governments seek to affect through lawmaking? How stable is the executive lawmaking agenda? How responsive is that agenda to changes triggered by elections or by transitions in prime minister? This study uses a dataset of 3982 Australian bills introduced between 2000 and 2017 to answer these questions. While it finds considerable stability in the policy content of executive lawmaking agendas, the analysis also indicates that Australia's executive lawmaking agenda is more responsive to changes in prime minister than to changes in the party in power. As the first application of the comparative policy agendas approaches to government bills in Australia, this article offers new insights into executive lawmaking priorities during an especially turbulent period in Australian politics.  相似文献

The archaeological record of prehistoric Cyprus is rich, diverse, well-published, and frequently enigmatic. Regarded by many as a bridge between western Asia and the Aegean, Cyprus and its past are frequently seen from scholarly perspectives prevalent in one of those two cultural areas. Its material culture, however, differs radically from that of either area. Apart from the early colonization episodes on the island (perhaps three during the pre-Neolithic and Neolithic), evidence of foreign contact remains limited until the Bronze Age (post-2500 B. C.). This study seeks to present the prehistory of Cyprus from an indigenous perspective, and to examine a series of archaeological problems that foreground Cyprus within its eastern Mediterranean context. The study begins with an overview of time, place, and the nature of fieldwork on the island, continues with a presentation and discussion of several significant issues in Cypriot prehistory (e.g., insularity, colonization, subsistence, regionalism, interaction, social complexity, economic diversity), and concludes with a brief discussion of prospects for the archaeology of Cyprus up to and beyond 2000.  相似文献

西安城墙东门箭楼砖坯墙体风化因素研究报告   总被引:2,自引:2,他引:0  
论述了西安城墙东门箭楼的文化背景,实地考察了风化外状,并对风化外状进行了分类测试。通过对砖坯墙体材料进行化学全分析、X-射线衍射分析、吸水率测定(含他和系数)、冻融实验、泛霜实验、环境污染与水文气象监测资料的分析,研究了东门箭楼砖坯墙体不同风化外状的风化因素,同时对现代修缮用砖的理化性能及质量进行了评估。结果表明,温度的交替变化、水的冻结与融化使得砖坯裂解成碎块;干湿引起可溶盐的结晶与潮解以及自然界中的雨水、地面水或地下水、污染气体等通过溶解、水化、水解、碳酸化、氧化等方式,使得砖坯墙体表面酥碱粉化。同时说明研究适用于古建筑修缮使用的抗风化仿古青砖是当务之急。  相似文献

In recent years, cultural anthropologists have made notable progress in understanding the bewildering variety of material exchange transactions found among the aboriginal populations of highland New Guinea. One of the major findings of this work is that competitive exchange behavior may bring in its wake alterations in agronomic practices involving an intensification of production. That intensification is primarily a product of social behavior, rather than an adaptation to climate change or population pressure, is a significant conclusion that should influence the thinking of archaeologists as they investigate past episodes of agronomic change, including the origins of agriculture.  相似文献
