Spatial skill concentration agglomeration economies

Using the Brazilian census and administrative panel data, the present paper provides evidence that the spatial concentration of analytical skills generates positive wage externalities for all workers in the local labor market. We rely on shift‐share instrumental variables to overcome the endogeneity of skill concentrations. The observed externality is independent from the classical market size economies. The estimates are robust to geography, institutions and workers' sorting on unobservable abilities.     

Improvised Hybridity in the “Fixing” of Chinese Infrastructure Capital: The Case of Kenya's Standard Gauge Railway

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.     

The Making of a Regulatory Crisis: Restructuring New York City's Water Supply

Much practically orientated environmental research is marked by a polarity between functionalist abstraction and ahistorical normative discourse. This paper seeks to bridge the divide between theoretical and empirical research through a case study of New York City's water supply. Current processes of socio-economic restructuring are leading to negative environmental consequences obscured by a failure to extend analysis beyond limited temporal, spatial or sectoral scales. Insights from regulationist theory show that a combination of fiscal, political and other developments are bringing about a wide-ranging reformulation of existing patterns of environmental regulation and service provision in the city. The power of the state is being radically diminished in relation to the power of capital and a plethora of different interest groups. A relatively simple centralized model of environmental regulation is being transformed into a complex decentralized pattern involving the emergence of new approaches to urban governance. Further research is needed on the contradictions between capitalist accumulation and environmental regulation at different spatial scales in order to link New York's changing role within the global economy to the declining political legitimacy and fiscal capability of the state to play an extensive role in environmental management.     

San Juan,the Fragile City: Finance Capital,Class, and the Making of Puerto Rico's Economic Crisis

This paper narrates Puerto Rico's fiscal and financial crisis through a reading of San Juan's urban landscape. We underscore the role of capital in the city, primarily embodied by the local capitalist class (the Criollo bloc) and foreign capitalists. Historically excluded from the manufacturing sector (dominated by US capitalists), the Criollo bloc accumulates its wealth by concentrating financial assets in the city. In times of crisis, the Criollo bloc resorts to the acquisition of new assets and asset exchange with foreign capitalists to remain solvent and provide short‐term solutions to the state's fiscal and financial limits. The survival of the local capitalist class, we demonstrate, is dependent on asset stripping. Drawing on Clyde Woods, we document how asset stripping unevenly redistributes wealth and risks along class and racial lines within a colonial economy. The finance capital/asset stripping basis of San Juan's economy renders it an extremely fragile city, we contend.     

人流联系和经济联系视角下区域城市关联比较——基于手机信令数据和企业关联数据的研究

手机信令数据所代表的人流联系与国内外研究常用的企业关联数据在测度城市关联存在何种差异,尚缺乏明确的研究。本文以江西省北部地区为研究对象,分别以手机信令数据、企业关联数据测度城市关联,比较了两种城市关联与城市之间空间距离、人口规模的关系,比较了两种城市关联网络的层级、结构、腹地。主要研究发现：人流联系不仅集中在城市周边地区,而且集中于较高等级城市之间;经济联系则主要集中在较高等级城市之间。人流联系、经济联系受到城市人口规模影响均较小。人流联系显著地符合幂函数空间衰减规律。手机信令数据和企业关联数据是两种不同的城市关联数据,但可互为补充,较为全面地反映城市关联。     

‘IT'S ALL A QUESTION OF BUSINESS’: INVESTMENT IDENTITIES,NETWORKS AND DECISION‐MAKING IN THE CLEANTECH ECONOMY

Cleantech has emerged in the last decade as a major new investment sector at the forefront of the green economy. It responds to the need for innovative technologies to combat the impact of global environmental, climate and resource trends. Focusing on the cleantech sector, this article explores the central importance of relationality within the financial domain of the green economy. The central aim of this article is to deepen understandings of the operation of cleantech investment by examining the decision‐making processes of cleantech actors, how these are influenced by (and influence) cleantech investment networks, and the relationships between these factors and the macro‐level drivers and discourses focused on the cleantech sector. A relational economic geography approach is used in conjunction with other frameworks (spanning the cultural, structural and actor‐network dimensions of cleantech investment) to investigate: how cleantech investors define the sector; the macro‐ and micro‐level drivers of cleantech investment; and how cleantech networks form and operate to create and disseminate cleantech discourses and to generate the mutual trust and information sharing needed to secure cleantech investments. In so doing, the article seeks to shed greater light on the micro‐level processes contributing to the creation and growth of cleantech investment markets as an essential catalyst and component of the green economy.     

Unpacking “Accumulation By Dispossession”, “Fictitious Commodification”, and “Fictitious Capital Formation”: Tracing the Dynamics of Bahrain's Land Reclamation

We explore the interrelationships between the concepts of fictitious commodities, fictitious capital and accumulation by dispossession. We do so through a detailed examination of the dynamics of land reclamation in the Kingdom of Bahrain during the years 2001–2014. Particularly, we dissect in‐depth the ensemble of social relations and chain of events involved in two specific real estate projects, Norana and Bahrain Financial Harbour, that have come to symbolize Bahrain's neoliberal era. Reclamation was a unique process in which land was explicitly produced as a commodity for market purposes. Primary material of land deeds, company registration documents, and news articles were used to map out the social relations across the state–finance–real estate nexus. We emphasize that our understanding of accumulation by dispossession involving land is greatly enhanced if we view it as a process of reconfiguring the ensemble of social relations using fictitious commodification and fictitious capital formation.     

Biomechanics of coaching maximal instep soccer kick for practitioners

Kicking in soccer has been the subject of scientific research for more than 40 years yet review articles summarizing the biomechanical fundamentals of kick optimization as a guide to coaching are scarcely to be found. The current review article aims to bridge the gap between scientific research into the maximal instep kick (including studies employing 3D motion capture and full-body biomechanical modelling) and the application of such research in coaching. It does so by supplying a scientifically founded, coaching-friendly article explaining identifiable characteristics and motor control sequencing that define this skill. Relevant biomechanical factors are identified in a way that should help coaches better develop training programmes and, at the same time, foster better understanding of the skill among athletes. Such information will contribute to both accelerated skill acquisition and, by concomitant gains in skill efficiency, the development of programmes that minimize risk of injury to athletes during training.     

The Mythical Shapeshifting of Capital and Petrification of Labour: Deepening Conflict on the Agrofuel Frontier

In the great civilisations of the past, shapeshifting promised a restoration of order in turbulent times in return for the deference of loyal subjects. It was a strategy of the powerful to maintain advantage and could also be used to bind opponents to an undesired form. This study finds its resonance in the contemporary shapeshifting that is the supposed transition from the fossil fuel economy. With reference to the fusion of oil, grain and sugar companies in Brazil's ethanol sector, it explores how amidst economic, environmental and political insecurity these “old villains” of the carbon economy have fused and emerged as the “new heroes” of the green economy. Accounts of dissenting rural subjects, however, unveil the mythical nature of avowed social gains from this shapeshifting. Amidst rural conflict and a successive weakening of regulation, it becomes evident how their petrification, in a metaphorical and increasingly literal sense is required.
