Structural characteristics of social networks have been recognized as important factors of effective natural resource governance. However, network analyses of natural resource governance most often remain static, even though governance is an inherently dynamic process. In this article, we investigate the evolution of a social network of organizational actors involved in the governance of natural resources in a regional nature park project in Switzerland. We ask how the maturation of a governance network affects bonding social capital and centralization in the network. Applying separable temporal exponential random graph modeling (STERGM), we test two hypotheses based on the risk hypothesis by Berardo and Scholz (2010) in a longitudinal setting. Results show that network dynamics clearly follow the expected trend toward generating bonding social capital but do not imply a shift toward less hierarchical and more decentralized structures over time. We investigate how these structural processes may contribute to network effectiveness over time.  相似文献

Rates of car ownership in Australia are among the highest in the world. Private cars have shaped the urban form of Australian cities and the daily routines of their residents, making it possible to fulfil geographically stretched responsibilities for work, family, and social lives. But the dominance of the private car in Australian lives and landscapes should not be confused with universality. Aggregate, population‐wide statistics of car ownership and use mask the fact that not all Australians are equally car dependent. In this paper, we report on the results of a household sustainability survey conducted in metropolitan Sydney and Wollongong. Overseas‐born persons, migrants, and (some) ethnic minority groups were found to own fewer cars – and to use them less – than their Anglo‐Australian and Australian‐born counterparts. These differences were not attributable to socio‐economic or demographic factors. Our findings, which point towards the existence of diverse cultures of transport within the Australian population, are significant for transport planning and policymaking. Given profound concerns about the environmental implications of car use, the environmentally (more) sustainable transport behaviours of ethnic minorities and migrants should be supported. A shift in research focus away from the most car‐dependent groups in Australian society may also be more widely instructive. The transport practices, experiences, and strategies of those who own and drive cars at below‐average rates may indeed contribute practical lessons to inform planning for more environmentally sustainable transport futures.  相似文献

The article deals with the use of metal ties in an ancient and stratified urban context, the city of Genoa, starting from the notarial documents preserved in its State Archives. The work has different objectives: to show the results that can be obtained, on an urban scale, thanks to a research path that compares indirect sources of different types with the observation of historical buildings; to highlight the “weight” and the role that the ties, often hidden, had in buildings, and not only the monumental ones; to increase knowledge of the production process of this constructive element. The wide and diversified use of metal ties found in Genoa seems to proceed in parallel, in the 15th century, with the development of a flourishing productive and mercantile business based on the commercial monopoly of the hematite of the island of Elba by the city oligarchy and, between the 16th and 17th centuries, with the huge investments in the construction sector highlighted by the abundant documentary sources.  相似文献

ABSTRACT

This paper explores how global innovation networks (GIN) within multinational companies (MNCs) act as extra-regional sources for path development in a regional innovation system (RIS) specializing in the oil and gas sector. We combine the literature on intra-firm knowledge dynamics in MNCs’ GIN with the literature on RISs to better understand their interrelatedness and their dynamics. Based on interviews with 15 MNCs located in the south-west of Norway, we find that firms are highly dependent on competence throughout the MNCs’ entire networks, as well as interaction with the overall RIS. The findings expose that MNCs’ GINs can act as extra-regional sources for path ‘extension’ in thick and specialized RISs through intra-firm mobility, observation and sharing of routines and best practice, mainly resulting in incremental innovations. We find some signs of potential path ‘renewal’, including radical innovation ideas. However, there are hampering factors linked to strong internal competition for innovation projects, pressure for local profitability and ownership motivation. At the level of RISs, new initiatives going beyond existing cluster initiatives and specializations need support.  相似文献

The dominating form of analysis in the transport sector is cost–benefit analysis (CBA). This study investigates the purpose and use of an alternative analysis intended to complement CBA in the Swedish high-speed rail project. According to CBA calculations, the project is heavily unprofitable. While some politicians called for project termination, the project leadership launched an alternative benefit analysis that calculated only benefits (disregarding costs). This was intended to be a basis for decision making on station localization and financing agreements, but it was quickly downplayed due to its methodological inconsistencies. However, the project leadership still used the identified benefits opportunistically as a counterweight to the negative CBA results. They also engaged local-level civil servants and politicians in making the reports. This built political momentum and made the local-level civil servants and politicians adopt the mindset of the project. This study shows how a methodologically flawed analysis is used for political manoeuvring. From a scientific CBA perspective, this is alarming, but from a political perspective it is not surprising. The findings echo earlier research showing that analysis for decision making is often used for political purposes. The results suggest that future research should consider how opportunism in alternative benefit analysis can be limited.  相似文献

This article offers a detailed ethnographic account of how people appropriate available space in compartments for disabled people in the Mumbai suburban trains, make it their own and monitor it, in the context of a succession of recent spatial changes. These compartments have increased in size over the years, and subsequently, the body of travellers has become more diverse. Passengers produce hierarchies based on need, physical differences, age differences and physical appearance, determining who can enter the compartments and who can’t, who can sit and who should stand, and where they should sit/stand. These hierarchies are mediated, but not dominated, by medical and disability certificates which are, in addition to a valid ticket, the documents that entitle people to travel in the handicapped compartments. Hierarchies are influenced by sexism, classism and audism and partially overlap but also are competing, such as in the case of deaf people who argue for the right to occupy seats and at the same time struggle with how to balance this quest with the need to act morally towards fellow travellers who seemingly suffer.  相似文献
