Updating Numerical Models of Masonry Arch Bridges by Operational Modal Analysis

This article aims at presenting and discussing the strategies for updating the finite element numerical modeling of stone masonry arch bridges using operational modal analysis. The study comprehended three bridges: two old ones, the St. Lázaro and the Lagoncinha bridges, and a recently constructed bridge in Vila Fria, Portugal. Updating of the bridge models is performed by comparing the numerical and experimental modal parameters. Three-dimensional detailed numerical models are used to perform modal analysis of the bridges. Experimental modal identification of the bridges is based on the measurement of their acceleration responses during normal operation. The assigned material properties are also based on available results obtained from in situ and laboratory tests and on the results of visual inspection and historical research carried out for both old bridges.

Gender equality: a core dimension in Rural Development Programmes in Austria?

The supranational gender equality regime of the European Union (EU), in place since the 1990s, affects gender-related social policy including the so-called ‘gender-neutral’ policy fields such as the common agricultural policy and rural development policy. Especially, the implementation of gender equality in all policy fields through the strategy of gender mainstreaming in EU Structural Funds and Rural Development Programmes has become a key challenge for political and administrative players and stakeholders. Analysis reveals that the existing institutional, political and social barriers for an effective implementation of gender equality in rural development policy are manifold. Instead of promoting rural women's agency and empowerment, Rural Development Programmes and processes in Austria are preserving and perpetuating traditional gender roles and patriarchal structures in rural society.     

Thinking Past Henri Lefebvre: Introducing “The Theory of Ground Rent and Rural Sociology”

This introduction to the translation of Henri Lefebvre's 1956 essay “The theory of ground rent and rural Sociology” moves through three stages. First, it suggests that Anglophone appropriations of Lefebvre have tended to focus too much on his urban writings, at the expense of understanding his early work on rural sociology, and failing to recognise how his urban focus emerged as a result of his interest in rural–urban transformation. Second, it provides a summary of his wider work on rural questions, including his unfinished work on a major treatise of rural sociology; and outlines the key themes of the present essay in relation to these other projects. Third, it connects Lefebvre's issues to wider debates in political economy and geography about aspects of the rural, land and ground rent, not least including the work of Antonio Gramsci and José Carlos Mariátegui.     

Land-Use Planning in Norwegian Mountain Areas: Local Development or Nature Protection?

This article discusses how land-use planning and management can combine the aim of local development with the protection of mountain areas. The basis for this double approach comprises protected areas and the land-use element of the Municipal Master Plan according to the Nature Diversity Act and the Planning and Building Act (PBA), respectively. Case studies performed in six mountain municipalities show that the planning processes in general are performed by a combination of rationalistic and communicative rationality based on consensus and with little awareness of power structures. Today's two-part system is dominated by the interests backing protection, not only in the protected areas, but also in the buffer-zones. Though the conflicts are rather few, they nevertheless often seem deep-set and rooted in national–local power relations. We argue that a more agonistic and decentralized approach where the protection-area management is transferred to the PBA will, to a larger extent, be able to combine both use and protection and to stimulate local development in mountain municipalities.     

Being NGO girls: gender,subjectivities and everyday life in Kolkata

This article discusses the role of non-governmental organizations (NGOs) as a cultural and political force in shaping the gendered and classed subjectivities of young women growing up in ‘red-light areas’ in Kolkata, India. It foregrounds the flexible deployment of NGO gender narratives by ‘subjects’ of NGO development to improve their everyday lives. Drawing on debates of NGOization, post-colonial urban Indian femininities and intersectionality, it demonstrates how several young women who grew up as ‘subjects’ of NGO development mobilize, reject and improvise contested NGO-inspired femininities for their everyday gain. At the same time, it illustrates how NGO gender narratives that are useful to some young women in their renegotiation of gender norms are deemed ineffective, if not obstructive, by other young women, particularly those whose lives remain entangled in multiple marginalities.     

Crowdsourcing Model Research for the Identification of Post-Earthquake Rescue Objects

The quick and accurate identification of post-earthquake rescue objects can minimize the casualties and property loss caused by earthquakes. With the rapid development of remote sensing technology, rescue objects can be identified through high-resolution remote sensing images. There are two main categories of approaches to identify rescue object through high-resolution images: automatic extraction by a computer and visual judgment by professionals. Although results can be obtained quickly by using automatic extraction, the accuracy of the results is unacceptably low. For visual judgment, the large demands for time and professionals restrict its wide practical application. In this study, we introduce crowdsourcing into the identification of post-earthquake rescue objects. First, we integrate the advantages of the computer and crowdsourcing, which means that the computer takes advantage of the speed of information processing, while crowdsourcing makes full use of human recognition capabilities. Second, we take visual judgment tasks out of the hands of professionals and entrust the tasks to workers in a crowdsourcing platform. Not only are the human resources infinite, but we can also improve the efficiency of identifying rescue objects. Third, we propose a crowdsourcing model that improves the quality of the results and saves human resources. Finally, experimental results demonstrate that our solution is feasible.     

Too few nutrients and too many calories: climate change and the double burden of malnutrition in Asia

About half of children age under five worldwide who are classified as undernourished (84 million out of 151 million) or overweight or obese (17.5 million out of 38 million) live in Asia. Tackling malnutrition in Asia is however fairly complex since the nutritional transition, a consequence of rapid economic development and globalisation, made many Asian nations undergo the simultaneous burdens of under- and over-nutrition. The dual burden of malnutrition is characterised by a concurrence of undernutrition along with overweight and obesity within the same individual, household, community, region and/or country. Providing that household food security is closely linked to malnutrition, this raises questions about the implications of climate change on the dual burden of malnutrition. That climate change affects food availability, access, utilisation and stability is evident. Accordingly, households facing food insecurity due to climatic shocks may allocate food differentially. Adult members may receive low-cost high-calorie food inducing obesity, whilst children receive nutrient-poor foods leading to undernutrition. Little is known about the climate impacts on the double burden of malnutrition and how this affects population subgroups differentially. This Editorial discusses the potential impacts of climate change on the double burden of malnutrition and concludes with the recommendation of strategies to tackle the issue.     

Welshness in ‘British Wales’: negotiating national identity at the margins

Popular interpretations of national identity often focus on the unifying qualities of nationhood. However, societies frequently draw hierarchical distinctions between the people and places who are ‘most national’, and those who are ‘least national’. Little attention is paid to these marginal places within the nation and the experiences of their inhabitants. This article helps to address this by analysing the ‘less Welsh’ British Wales region of Wales, a country that has traditionally possessed a hierarchical, regionally constituted nationhood. The article studies the British Wales region both ‘from above’ – considering how some areas develop as ‘less national’ – and ‘from below’, introducing empirical ethnographic work into ‘everyday Welshness’ in this area. Whilst previous work on hierarchical nationhood focuses on how hierarchies are institutionalized by the state, this article demonstrates how people at the margins of the nation actively negotiate their place in the nation. Whilst people in this area expressed a strong Welshness, they also struggled to place themselves in the nation because they had internalized their lowly place within the national hierarchy. The article demonstrates the importance of place and social class for national identity construction and draws attention to the role of power in the discursive construction of hierarchical nationhood.     

Linking Heritage Preservation and Community Development: An Assessment of Grassroots Heritage Based Projects as Vehicles for Socio-Economic Development and Sustainable Heritage Preservation in Zimbabwe

This paper engages the practical aspects of linking heritage, in particular, archaeological heritage, with both individual and community economic development. In recent years, there has been growing realisation that culture, inclusive of cultural heritage, can be both a driver and an enabler of economic development, especially in developing countries. However, few documented examples demonstrate the validity of such arguments. The paper explores some practical examples of how, at the grassroots level, individuals and communities are attempting to exploit archaeological heritage sites as well as other cultural and natural heritage resources for income generation in Zimbabwe. The major thrust of the paper is to assess the manner of use and the viability of such ventures. Since the ability of archaeological heritage to generate revenue and support people around the sites has a direct effect on long-term survival of such heritage, ultimately, the paper contributes to the discourse on linking heritage and economic development as well as the theme of sustainable heritage preservation.
