A Postcolonial Critique of Community Energy: Searching for Community as Solidarity in India and Scotland

Community renewable energy (CRE) represents a growing empirical and academic turn towards community‐based sustainability and climate change interventions. This paper brings together postcolonial theory and CRE for the first time to outline fundamental tensions in the conceptualisation and application of the idea of community. The understanding of community within the CRE discourse is largely: (1) location‐based; and/or (2) a community of choice that is consciously opted into. Driven by postcolonial theory, this paper counterpoises both as a form of community as contract against an idea of community as solidarity. Its central thesis is that actually existing community, contrary to how the bulk of CRE literature commonly understands it, is a combination of bonds of solidarity and emergent purposes. The paper conceptualises community as fluid bonds of solidarity that align and realign differently around different purposes.     

基于三维扫描模型的兵马俑足踝有限元分析

利用三维扫描技术获取兵马俑残片的三维点云数据,结合Geomagic Studio和Hypermesh建立高精度的兵马俑足踝残片三维实体网格模型。通过基于ABAQUS的重力作用下的有限元分析,研究足踝部分的Von Mises应力和变形特征,以确定足踝处的受力薄弱部位。为进一步探究模型各残片的最佳点云简化比例,采用点云简化模型进行相同工况的有限元分析,以验证点云简化的可靠性。结果表明:结构在重力作用下可保持安全稳定的状态,相对薄弱部位位于左腿足踝处;对于大部分残片,其最佳简化比例在60%～70%,简化后可有效缩短模型实体化处理时间;采用简化模型得到的有限元结果,其最大Mises应力相比于原始模型的误差小于15%,且应力云图和变形图形状接近,模型简化具有可靠性。     

Inca builders at Machu Picchu National Archaeological Park

Knowledge about the Inca measurement system is based on information from the colonial chronicles and modern studies of the 16th-century Quechua dictionaries. Based on those texts, we can presume that the Incas used an anthropometric system of measurement adopted from the proportions of the human body. Using cosine quantogram analysis and statistical verification, it is possible to verify the existence of the measurement system used by the Inca architects. For this purpose, a measurement series of architectural and water infrastructure elements were collected from 3D point cloud of the Chachabamba and Machu Picchu settlements in Machupicchu National Archaeological Park.     

MORE THAN MEETS THE FACT: THE UNIVERSALITY OF HISTORY AND THE COLONIAL MEDIATION

This article examines how mediation is not just limited to the format that's selected to convey the findings of previously conducted research that supposedly followed the conventional protocols of the historical discipline. Rather, it considers mediation as a fundamental part of building historical knowledge, for it assumes that every part of the historiographical operation can be defined as “mediation.” Specifically, it deals with colonial historical mediation, a concept that refers to the combination of an overt or concealed agenda, intentional or unnoticed bias, commonsense assumptions, inherited academic and political traditions, conceptual constellations, and more or less informed theoretical beliefs that configure the subtext upon which historical explanation is built, particularly in Latin America.     

Coloniality as a Barrier to Climate Action: Hierarchies of Power in a Coal-Based Economy

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.     

Political institutions,punctuated equilibrium theory,and policy disasters

This paper develops a theory of the relationship between policy disasters and political institutions. Policy disasters, defined as avoidable, unintended extreme negative policy outcomes, are important political, and historical events above that receive relatively little attention from political scientists and scholars of public policy. Using the predictions of punctuated equilibrium theory, I argue that systems with higher error accumulation will experience more policy disasters. Systems with more veto players and weaker information flows will experience more policy disasters, but information flows will have a stronger impact than veto players. I test this theory using data on financial crises and natural and technological disasters across 70 countries over 60 years. I find strong evidence that systems with weaker information flows and more veto players tend to have greater policy disaster risk.     

The prehistory of Cyprus: Problems and prospects

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.     

Patterns of exchange and the social production of pigs in highland new guinea: Their relevance to questions about the origins and evolution of agriculture

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.     

Middle-range theory,behavioral archaeology,and postempiricist philosophy of science in archaeology

This paper examines middle-range theory (MRT) within processual and postprocessual archaeology. An analysis of the Binford-Schiffer dispute serves as a means of clarifying what MRT in processual archaeology is or is intended to be. Postprocessualists, despite their vigorous criticisms of MRT-based approaches, are found to rely on the same resources and types of reasoning to make their inferences. In their practice they tacitly turn to processualist middle-range principles, and so the justification of postprocessual interpretations is equivalent to that of MRT-based processualist models. If the middle range is functionally defined — a space within a research program occupied by varying theories that are taken from the body of general theory to which the program is committed and that function as background knowledge in the verification of theories — MRT bridges the epistemological gap between processual and postprocessual approaches.
