Shake table tests of a new steel–asphalt composite layer system for the seismic base isolation of housing units

Base isolation is an effective way to reduce earthquake energy transfer from ground to structure, but existing seismic isolation systems are not very suitable for rural buildings for some reasons. A new steel–asphalt composite layer for the seismic base isolation of housing units is present in this paper. Its dynamic characteristics and isolation effect are studied by shake table tests of two full-scale specimens. Different earthquake waves with different peak ground accelerations (PGA, from 0.1 g to 0.4 g) are input. Test results show that the isolation layer could efficiently reduce the input acceleration. Moreover, as the PGA increase, the isolation layer shows good function of the displacement limit.     

Everyday effects, practices and causal mechanisms of ‘cultural embeddedness’: Learning from Utah’s high tech regional economy

In recent years, economic geographers have drawn extensively upon notions of ‘cultural embeddedness’ to explore how spatially variable sets of cultural conventions, norms, values and beliefs shape firms’ innovative performance in dynamic regional economies. However, our understanding of these causal links remains partial, reinforced by an ‘over-territorialised’ conception of cultural embeddedness which sidelines the role of institutional actors operating outside and across the boundaries of ‘the local’. So motivated, this paper offers a theoretically-informed - and theoretically informing - empirical analysis of the high tech regional economy in Salt Lake City, Utah to explore the everyday causal mechanisms, practices and processes - both local and extra-local - through which firms’ cultural embedding within the region is manifested, performed and (un)intentionally (re)produced. In so doing, this paper aims to further our understanding of the constitutive entanglement and complex interweaving of cultural/economic practices, and to contribute to the development of an in-depth empirical corpus of work which compliments the exciting conceptual developments that have largely dominated cultural economic geography over the last decade.     

“Love for sale”: Biodiversity banking and the struggle to commodify nature in Sabah,Malaysia

In Malaysia, second largest palm oil producer worldwide, logging companies, palm oil corporations, and even responsible citizens can now compensate their biodiversity impacts by purchasing Biodiversity Conservation Certificates in an emerging new biodiversity market: the Malua BioBank. Biodiversity markets are part of a wider trend of marketisation and neoliberalisation of biodiversity governance; introduced and promoted as (technical) win–win solutions to counter biodiversity loss and enable sustainable development. The existing neoliberalisation and nature literature has tended to analyse these processes as consequences of an inherent drive of capital to expand accumulation and submit ever more areas of nature to the neoliberal market logic.In contrast, I aim (a) to problematise the agency and the “work” behind marketisation of biodiversity, challenging the story of (corporate-driven) neoliberalisation as the realisation of an inherent market-logic (based on the a false conceptual state–market divide, often prevalent even in activist academic circles working on neoliberalisation of nature) and to see the state not only as regulator, but driving force behind, and part of “the market”; (b) to question the myth of neoliberalisation as state losing control to the market and to show how the state is using the biodiversity market as mode of governing; re-gaining control over its forests and its conservation policy; and (c) to demonstrate empirically the distinction between neoliberal ideology and practice, and to show that marketisation was based on pragmatic decisions, not ideology-driven political action. My analysis is based on 35 qualitative interviews with actors involved in the BioBank.

Local responses to changed circumstances: Coalmining in the market economy in Upper Silesia, Poland

It is argued that the emphasis of much recent research into coalmining has been placed on international and national scale influences which affect coalfields as a whole; change at the intra-coalfield scale has received less attention. After providing a background to events in Poland during communism, attention focuses on developments since 1989, commencing with coalfield-wide influences. There follows an examination of the work of the state body Państwowa Agencja Węgla Kamiennego, which executes government policy at the local level, and whose membership is drawn from the coalfield region. This agency recommends the closure and amalgamation of mines, but otherwise rationalisation measures are left to the seven mining companies and the colliery managers. The restructuring which has been carried out is considered under five heads: organisational change within the collieries, employment, production and technical change, and ecological adjustment. While recognising the importance of the socioeconomic and political environment and geology, there is much evidence to suggest that intra-coalfield patterns are strongly determined by local decision-makers.

Carrying Capacity of Marine Region in Liaoning Province

Carrying capacity is one of important studies on coordinating development of population,resources,and environment.At present,the researches on it mainly concentrate on the carrying capacity for population and economy,such as the water resources carrying capacity,the land resources carrying capacity,the environment carrying capacity,etc.Based on the related theories and methods,this paper creatively proposed the concept and meaning of carrying capacity of marine region,and formed the appraisal system.According to the developing situation of marine economy of Liaoning Province in recent years,and by employing the method of the state space,this paper also measured the carrying capacity and carrying state of marine region and discussed the sustainable problems of marine economy of Liaoning.The research results show that the carrying state of marine region of Liaoning is in the state of overloading at present,but taking a favorable turn.
