CODE PROVISIONS AND ANALYTICAL MODELLING FOR THE IN-PLANE FLEXIBILITY OF FLOOR DIAPHRAGMS IN BUILDING STRUCTURES

In this paper a review of the provisions of some modern seismic codes for the analytical modelling of the floor diaphragm action is made and a methodology using simplified 2-D finite elements models for monolithic floors is suggested, taking into consideration the in-plane flexibility of them. The simplified models use the coarsest discretisation mesh possible, simply taking into account all the connection points of the vertical structural elements on the diaphragm of each storey. The efficiency of the proposed simplified F.E. models is tested with comparative response-spectrum dynamic analyses of various building structures with different plan shapes, according to EuroCode 8 [EC8, 1994]. The simplified models provided excellent results for the dynamic characteristics of the entire building and the stress state of the framing substructure and a fair estimation for the in-plane stresses of the floor diaphragms.     

Blondel,the Philosophy of Action and Liberation Theology

Abstract

Maurice Blondel's philosophy of action and concrete political theology provide foundations for modern theologies of action. By commencing with the reflective subject, Blondel compensates the deficiencies of collectivist Marxist social analysis. He did not live to complete his account of the social, political and economic implications of his philosophy, but they are realized in the work and witness of others: Pierre Teilhard de Chardin, Yves de Montcheuil, Henri de Lubac and John McNeill. Liberation theologians of diverse persuasions need especially to acknowledge their debt to Blondel in an era when, in Western societies, the fundamental context of action is no longer material but intellectual, spiritual and interpersonal. The abstract nature of his thought means that he frequently opens suggestive paths into further reflection rather than prescribing complete solutions to specific practical questions.     

Public participation geographic information systems (PPGIS): challenges of implementation in Churchill,Manitoba

Public participation geographic information systems (PPGIS) increasingly are utilized in geographic research, yet researchers rarely are provided with guidance on how to implement PPGIS in an appropriate and effective manner. This article reports on the process of research that explores responses to current and future local tourism development offered by a sample of residents using a modified PPGIS approach called ‘community action geographic information system’ (CAGIS). The conceptual development of CAGIS is reported and the challenges encountered during its implementation in Churchill, Manitoba during 2005–2007 are reviewed. It is suggested that researchers wishing to conduct similar research should undertake thorough preliminary fieldwork to assess the likelihood of finding agreement on a common problem; acquiring adequate resources; establishing collective responsibility for the project's outcome; attaining stakeholder support; developing trust and meaningful relationships; and incorporating indigenous knowledge appropriately. Feedback of results to community members also should be an integral part of the research process. A number of feedback mechanisms are reported, including an interactive weblog, which helped facilitate communication between heterogeneous groups in Churchill. Although ambitions for a truly participatory GIS approach to this project have been set aside, it is held that PPGIS can yield positive outcomes for communities and academia. Sharing this research experience will be useful to others who venture into PPGIS research, especially in northern communities.     

Shutting Down the Machines of Destruction: Possibilities for Agrarian Life on the Protest Blockade

The protest blockade is one tool for seeking liberation from the state while living within it. I offer a critical analysis of the protest blockade in agrarian struggles for land and life in Indonesia and beyond. I specify my discussion with a retelling of a Sumatran land-back movement of smallholders and landless workers who twice turned to the blockade to reclaim their land from a plantation company. I consider how these blockades and others in Sumatra and Borneo created direct-action power, thereby expanding people's possibilities for livelihood and autonomy in landscapes of extraction and exploitation. Blockading action is a process that unfolds from within as activists challenge the legitimacy of their rulers and set out to create more emancipatory spaces and territories. When protestors blockade the bulldozers, logging trucks, and other machines of capitalist exploitation of workers and ecologies, they seek to disrupt the infrastructures and commodity flows of the dominant political-economic order as well as open up new agrarian possibilities. These protest blockades are central to the anarchist, Indigenous, and decolonial politics that motivate direct-action protests across the globe.     

The power of hope: the mobilisation of small and mid-tier companies in the mining industry's campaign against the Resources Super Profits Tax

This article examines the mobilisation of small and mid-tier companies in the mining industry's campaign against the Resources Super Profits Tax (RSPT), drawing on interviews with 18 industry players. The government anticipated that small exploration and development companies would support the RSPT, on account of its promise to contribute towards the costs of exploration and development. In doing so, it was guided by Treasury advice and the assumption of calculative rationality on the part of small companies. Instead, industry leaders forged a common front against the tax within days of its announcement. In doing so, they appealed to the hope of extraordinary returns – or what is sometimes described as ‘sentiment’, ‘animal spirits’ and ‘irrational exuberance’ – among mining entrepreneurs and investors, against the odds. Other researchers have argued that the debate around the RSPT highlights the ‘power of ideas’, but we argue that it highlights the ‘power of hope’.     

Transforming cross‐cultural water research through trust,participation and place

Indigenous voices in government‐led natural resource management planning processes are often marginalised, misinterpreted, or excluded. Third parties, including government‐employed geographers, can act as knowledge brokers in defining Indigenous values and interests so they might be included in government planning processes. This paper reviews and assesses a research partnership that evolved to document the complex and diverse ecological and hydrological values held by Ngan'gi speakers about the Daly River and connected water places in the Northern Territory, Australia. The development of trust through the slow building of a relationship based on place‐based dialogue, a key aspect of participatory action research (PAR), created the foundation from which a mutually beneficial and respectful research partnership was able to, and continues to, evolve. Both research partners' perspectives are revealed here to articulate why the research partnership was deemed a success. Key lessons learned from the research partnership include the importance of trust, respect for place‐based learning, researcher and institutional flexibility, and awareness of the intricacies of relationship building and the benefits that research engagement can bring to Indigenous people and communities. We aim to further dialogue among geographers and interested disciplines as to the potential for PAR methods to foster mutually beneficial Indigenous–non‐Indigenous research partnerships.     

Unwritten Factors Affecting Structural Funds: The Influence of Regional Political Behaviours on the Implementation of EU Cohesion Policy

While EU regional policy has the ambitious objective of supporting lagging regions and promoting inter-regional convergence, its impact is dependent on the ability of regional policymakers to secure and use EU funding to meet the region's needs. This paper aims to show under which conditions politics has a defining influence on the distribution, allocation and utilization of structural funds (SF), specifically in Objective 1 regions. The empirical analysis focuses on the 2000–2006 programming cycle in France, Germany, Italy, Spain and the UK. The results show that regions politically aligned with national governing coalitions tend to perform better in terms of received SF support and enjoy more flexibility in implementing SF. However, the influence of regional political behaviours on economic performances is very limited. The findings confirm the importance of politics in influencing SF implementation, but its limited influence on economic outcomes.     

Collective Action and the Evolution of Intergovernmental Cooperation

Voluntary cooperation among governments holds tremendous promise for solving policy problems with regional and national scope. In this article, we apply insights from the theory of institutional collective action to understand the evolution of cooperative governmental institutions. We address the question: What makes a government decide to exit an existing cooperative arrangement and join a new one with a stronger central authority? Our empirical analyses examine state choices about whether to participate in the new Interstate Compact for Juveniles or remain in an existing compact that serves the same purpose. The findings shed light on how governments make trade‐offs between their desire to maintain their autonomy and the need to overcome the transactions costs, coordination problems, and free‐rider problems associated with cooperative governance in order to achieve policy gains.     

The polis and the res publica: two Arendtian models of violence

The influence of the ancient Greek world on Hannah Arendt’s thought is well documented, yet her interest in the politics of the Roman Republic is often considered less central to her work. This paper explores Arendt’s analysis of both these political worlds, with a particular emphasis on what this comparison can tells us about her understanding of the role of violence in politics. Arendt has generally been understood to structurally exclude violence from the political, in part due to the claims she makes in her later essay ‘On Violence.’ Yet in her portrayal of Roman politics, and her preference for this political system above the Greeks’ (in certain respects), a genuinely political engagement with violence can be discerned. The paper claims that this particular case study indicates the framework of the vita activa, set out by Arendt in The Human Condition, should be reinterpreted, particularly insofar as ‘fabrication’ or ‘work’ here appears as something that is legitimately part of the political, and incorporates within it some forms of violence. The claims that violence is structurally anti-political, this paper concludes, are temporally specific to a twentieth-century context, rather than constituting a foundational ‘rule’ of political practice for Arendt.     

Generating a voice among ‘media monsters’: hybrid media practices of Taiwan’s Anti-Media Monopoly Movement

This article assesses how social movement actors strategically use a hybrid mix of social and traditional media to organise political actions in an attempt to influence media and public agendas. Using the case study of the Anti-Media Monopoly Movement in Taiwan, it investigates how the activists’ use of social and mainstream media contributed towards their collective action and mediated visibility. We argue that the effectiveness of social media activism is augmented by the activists’ engagement in protest actions and tactics catering to news media logics. Through their hybrid media practices, the activists were able to mobilise local and overseas groups into forms of collective and connective action and amplify the impact of protests.
