Description and characterization of place properties using topic modeling on georeferenced tags

ABSTRACT

User-Generated Content (UGC) provides a potential data source which can help us to better describe and understand how places are conceptualized, and in turn better represent the places in Geographic Information Science (GIScience). In this article, we aim at aggregating the shared meanings associated with places and linking these to a conceptual model of place. Our focus is on the metadata of Flickr images, in the form of locations and tags. We use topic modeling to identify regions associated with shared meanings. We choose a grid approach and generate topics associated with one or more cells using Latent Dirichlet Allocation. We analyze the sensitivity of our results to both grid resolution and the chosen number of topics using a range of measures including corpus distance and the coherence value. Using a resolution of 500 m and with 40 topics, we are able to generate meaningful topics which characterize places in London based on 954 unique tags associated with around 300,000 images and more than 7000 individuals.     

The Social Construction of Tourist Places

Ordinary places become tourist places when they are attributed particular meanings and values which appeal to and attract tourists. In this sense, tourist places are socially constructed and negotiated phenomena. This paper explores place meanings in the context of the Daintree and Cape Tribulation area, Far North Queensland, Australia. Two components of place meaning were examined. Firstly, the meanings of place produced by the tourist industry and, secondly, the meanings of place consumed by tourists visiting the area. There existed significant overlap between these constructions in spite of potentially conflicting on-site evidence, suggesting that actual experience of place does not significantly affect place meanings. This was confirmed by a comparison between different groups of tourists, which revealed that the meaning attributed to place was influenced by pre-visitation variables, including existing knowledge, and environmental preferences and experience. A conceptual model of tourist places is proposed, which argues that the success of a tourist place depends on the level of consensus on meanings negotiated between the systems of place production and place consumption.     

Environmental awareness,the Transition Movement,and place: Den Selvforsynende Landsby,a Danish Transition initiative

The Transition Movement, originating in Ireland and the United Kingdom, gathers and supports community-led actions to meet the global challenges of climate change, peak oil and energy descent. In our study we analysed a Transition Network project, a Danish village built from scratch by its inhabitants and named the Self Sufficient Village (SSV). Employing the theories of constructed landscapes and place attachment, we studied how the Transition Movement ideology shaped the constructed landscape of the village and influenced the inhabitants’ attachment. The research team, following the grounded theory approach, conducted a field study staying in SSV. We collected data with focus groups, individual interviews and participatory observations, taking part in daily life of the community. The analysis revealed three, intertwined themes which altogether create the constructed landscape of SSV. They were named Community, Ideology, and Individual impact, respectively. Our findings showed that the community and strong social ties were predominant factors in shaping place attachment. Transition ideology and environmental awareness, although less pronounced, still turned out to be vital for the feelings of belongingness and empowerment, resulting in a positive impact of the village on the local scale. Using our case study as an example we discuss the importance of environmental concern and place attachment for similar grass-root initiatives.     

My country or my planet? Exploring the influence of multiple place attachments and ideological beliefs upon climate change attitudes and opinions

Research on people-place relations, specifically place attachment and place identity, is beginning to make an important contribution to understanding human responses to climate change. However, to date there has been a dearth of research on how place attachments at multiple scales, particularly the global, and individual level ideological beliefs combine to influence climate change attitudes and opinions. To address these gaps, survey data was collected from a representative sample of Australian citizens (N = 1147), capturing attachments at neighbourhood, city/town, state/territory, country and global scales, as well as a range of climate change belief and individual difference measures. Results show the importance of the interplay between national and global place attachments. Individuals expressing stronger global than national attachments were more likely to attribute climate change to anthropogenic causes, to oppose hierarchy-enhancing myths that legitimize climate inaction, and to perceive positive economic impacts arising from climate change responses, in comparison to individuals indicating stronger national over global place attachments. Individuals with stronger global than national attachments were more likely to be female, younger, and self-identify as having no religion, to be more likely to vote Green and to be characterized by significantly lower levels of right wing authoritarian and social dominance beliefs. Right wing authoritarian and social dominance beliefs mediated the effects of place attachments upon climate change skepticism. Explanations for the findings and implications for future research are discussed.     

Forms and sources of place attachment: Evidence from two protected areas

Sense of place is a widely researched concept that has been used to describe and analyze people–place relationships. However, there is no consensus regarding the forms of place attachment, the relative importance of the sources for such attachments, or the spatial extent of place formation. The purpose of the paper is to contribute case examples of sense of place for significant natural areas, thereby adding to the body of evidence that explicates the diverse sources and forms of place attachment. Using content analysis of qualitative stakeholder interviews, we identify these dimensions of place attachment for two nationally significant Australian natural areas. Our data support a tripartite structure for sense of place comprising affective, functional and cognitive forms of attachment. We also examine the extent to which these place attachments are localized on the study sites and/or spatially generalized across sites possessing the same sources of place formation. Our case studies provide evidence for both localized and generalized senses of place. Localized place attachments had affective and functional components, respectively founded on social and biophysical sources. Generalized senses of place comprised functional and cognitive components, with appreciation of historical values of these places key to the formation of the latter. Our results indicate the spatial diversity of place attachments for protected areas and their social, cultural and biophysical sources.

Locating diversity: race,nativity and place in health disparities research

Nancy Krieger has been one of the leading voices in documenting how social ‘axes of difference’, including race, ethnicity and class make people vulnerable to poor health and limit their access to effective health care. We discuss the importance of ‘locating’ diversity in health inequalities research. This includes critically dissecting racial and ethnic axes into more nuanced social categories that incorporate differences based on immigration and other factors. It also involves considering how diverse population groups vary in their perception and use of space for health-related activities and exposures. Examples relating to immigrant populations’ health and access to health care are discussed.     

“It’s a gestalt experience”: Landscape values and development pressure in Hawke’s Bay, New Zealand

Demand for both primary residences and second homes in high-amenity areas has led to escalating property values and widespread development pressure in coastal New Zealand. We focus on a major development proposal at Ocean Beach, a greenfield coastal site in the Hawke’s Bay region, and seek to explain the opposition it has provoked. In so doing, we address three questions: first, what landscape values are articulated within the planning process; second, what is the anticipated impact of 1000 new dwellings on those values; and third, how does place attachment figure in the ensuing debates. We address these questions though a thematic analysis of data derived from official reports and proposals, planning submissions, and key informant interviews. We find Ocean Beach to be a place that offers a quintessential coastal experience, often linked to youthful memories. Additionally, the site is valued for its accessibility and wilderness qualities - perceptions heightened by awareness that areas of undeveloped coastline relatively close to population centres are increasingly scarce. We contend that such sites are doubly valuable: in a formal sense, as natural landscapes whose processes and forms receive regulatory protection; and in an informal sense, as sites that generate human meaning, including emotions such as nostalgia, freedom and belonging.     

Has river rehabilitation begun? Social perspectives from the Upper Hunter catchment, New South Wales, Australia

Recognition of the degraded state of rivers across the world has prompted the development of management programmes which promote river repair through rehabilitation practices. Efforts to date have emphasised concerns for biophysical attributes of rivers to the relative exclusion of socio-cultural values. Ultimately, the process of river repair must move beyond this technical focus and incorporate collective societal engagement, participation and ownership. However, the inherent complexities of informing and managing this process limit the prospects that engagement will be translated into an effective and sustained practice. This qualitative case study research analyses the community’s knowledge, views and opinions regarding geomorphic river change and river works projects undertaken in the Upper Hunter catchment, New South Wales, Australia. The responses and views expressed by the participants highlight how ineffective communication and limited understanding of past river work practices has inhibited the connection and ownership between the people and their river. Essentially, historical river management was viewed as a technical process that failed to incorporate social values and aspirations, and which gave inadequate consideration to local knowledge and experience. Participants identified the need to address both diversity and commonality in vision-building and the need for greater confidence and transparency in river science and management. In light of these responses, this paper argues for the adoption of a geo-social, transdisciplinary approach to river rehabilitation.     

The cultural politics of local economic development: meaning-making, place-making, and the urban policy process

A major concern of work in urban and political geography in recent decades has been to analyze how and in whose interests local space economies are produced and reproduced. A common focus is on the role local elites play in gathering support for their development agendas. Drawing from these literatures, this paper focuses on how various visions of the future of localities are contested in the local policy process. It argues that this struggle can be usefully understood as a cultural politics in which meanings are defined and struggled over, where social values are naturalized, and by which `common sense' is constructed and contested. The use of the term `cultural politics of local economic development' is, then, intended to indicate that meaning-making and place-making occur simultaneously in struggles over the future of space economies. It is also an attempt to overcome the problematic distinction between `culture' and `economy' that continues to haunt a great deal of work on urban politics. Through a case study of urban politics in Lexington, Kentucky in which discursive strategies are highlighted, it is argued that this approach is useful in that it provides insight into non-elite perspectives on local economic development and that it underscores the role played by everyday life in constituting political action. The paper concludes by suggesting that any problematization of the conceptual distinction between `culture' and `economy' must be carried out in and through detailed analyses of how groups involved in social struggle frequently construct rhetorical strategies in reference to it.
