State as resource,mediator and performer: understanding the local and global politics of gold mining in Kyrgyzstan

The inability of the state to maintain security and the rule of law for the purposes of foreign direct investment and industrial production is often taken as a sign of its weakness. However, such judgments say little about the actual functions of the state for global extraction industries and local political forces which demand their share of the pie. Whilst coercive state power may have decreased since Kyrgyzstan became independent, more important is the fact that the state itself has been transformed under the ruptures of, on the one hand, economic and political liberalization and, on the other, the effects of so-called ‘revolutions' of 2005 and 2010 which led to the wholesale restructuring of national structures of clientelism. Based on ethnographic research conducted in Talas province, documentary sources and interviews with gold mining companies and state officials, the paper investigates the state's shifting roles with respect to Kyrgyzstan's gold mining sector. Firstly, it explores the state as a source of rents for officials who grant and rescind licences in exchange for formal and informal payments from foreign investors, often via offshore vehicles. Secondly, it considers the role of the state as mediator between foreign investors and their access to sites. Finally, it identifies the state as performer of its status as sovereign power despite its inability to prevent uprisings and actually guarantee the promised access to its territory.

商业银行开展黄金业务的金融思考

黄金是稳健、保值的理财产品。由于国家对黄金的严格管制，中国黄金投资市场与国内其他金融投资市场相比，发展起步晚、市场容量小、产品过于初级与单一。随着中国金融领域逐步与国际接轨，黄金投资市场改革发展步伐将明显加快，这为商业银行的业务发展提供了良好的契机，民间浓厚的黄金情节将使中国的黄金市场更加繁荣，可以预见，商业银行涉足黄金投资业务具有广阔的发展前景。

The Global Gold Mining Industry,Junior Firms,and Civil Society Resistance in Guatemala

Over the past two decades, the gold mining industry has increased its activity in Latin America. Growing contestation and conflict around gold mining projects have accompanied this shift. This article draws from the case of Guatemala, where metal exploration has grown by 1,000 per cent since 1998, to illustrate how the proliferation of small ‘junior’ firms – together with neoliberal investment policies and suitability of mineralisation – set the stage for fly‐by‐night gold mining and, therefore, intense resistance from host communities to mineral development.     

The centrality of labor time in South African gold mining since 1886

Labor time, as a dimension of South African mining labor history, has been ignored, both conceptually and historically. This article remedies this yawning gap by presenting primary and secondary evidence which demonstrates the centrality of labor time in South African gold mines since the discovery of gold in 1886. To this end, labor time is traced in two ways. Part I tracks industrial working time by tracing the length of the working day and week. Part II tracks the ever-increasing length of the African migrant labor contract. While industrial working hours remain remarkably stable for almost a century, the migrant labor contract systematically increases over a similar period. These two measures of labor time eventually coincide when the migrant labor system dissolves and black African workers take annual leave together with their compatriots across the racial divide. The explanation for the mining industry’s long struggle to both maintain relatively long working hours and increasingly maximize the length of the migrant labor contract is construed as completing the received wisdom of Harold Wolpe's much celebrated and criticized `cheap- labor' thesis. (Wolpe, “Capitalism and Cheap Labor Power.”)     

Russian Constitutional Crisis: Law and Politics Under Yel'tsin

This article is a foray into the understudied issue of environmental protest politics in Central Asia. Specifically, it uses Kyrgyzstan as a case study to test the argument that environmental concerns mobilized people to engage in protest and in ways different from other kinds of protest. This essay presents the first systematic study of public opinion about the environment in Kyrgyzstan. It includes results from a 2009 nationwide survey, over 100 expert and elite interviews, and newspaper content analysis. Furthermore, it spatially analyzes these results to identify geographical variation in public perception and political event occurrence patterns. Protest engagement is a complex process determined by the interaction of several factors, and is not explained solely by affluence, rationality, or grievances. Eco-mobilization – collective political action about the environment – represents a class of protest events that offers a different view into mass discontent in the former Soviet Union and neo-patrimonial societies. The study finds that these political actions about the environment are not necessarily elite driven; there is a basic foundation of national concern and salience of these issues, and demonstrated environmental beliefs do help to explain protest behavior.
