Visualising everyday geographies: practices of vision through travel-time

Responding to recent debates in human geography on the need to explore more complex renderings of everyday visuality, this paper explores some of the fluid relationships between everyday visuality, materiality and mobility through practices of contemporary railway travel in Britain. Based on extensive empirical research, this paper explores three different but related visual practices experienced during the course of a railway journey. First, it looks at how sublime forms of vision emerge to produce a variety of passive embodied effects. Second, it looks at how more attentive visual practices are implicated in the temporal organisation of the journey and have the capacity to activate changes to routine. Third, it looks at how the physical materiality of the carriage interior serves to mediate the visual field in particular ways and gives rise to a series of freedoms and constraints. Whilst the visual consumption of landscapes viewed through a window is often taken to be an axiomatic part of the travelling experience, this paper demonstrates the importance of apprehending how a multiplicity of visual practices affect how perceptions of time, space and location unfold over the course of a journey.     

Negotiating spatial identities: mobile perspectives on street life in uganda

Previous geographical research with street children has principally focused on their micro-geographies in the city. This paper draws on nomadic and episodic processes of homeless mobility, to explore street children's geographies from a wider social, spatial and temporal perspective. By examining street life in Kampala, Uganda as a continued negotiation of public/private and street/non-street locations, the fluid nature of street children's identity is illustrated. Over time, movement between spaces, such as divergent city niches, institutions, homes and other towns, is often subject to power relations operating in street/non-street spaces with each requiring conformity to a different set of values and behaviours. The paper demonstrates how this results in children's street identity changing as they move through the street life path.     

Small things in perspective: the contribution of our blind tests to micro-residue studies on archaeological stone tools

Our blind tests are distinctive for they were conducted on replicated stone tools used for a variety of tasks that included the processing of animal remains and plants. The analyst was required to differentiate an array of residues from microscopic morphological characteristics, using light microscopy. The original aim of our first tests was to assess the analyst's ability to identify a variety of plant and animal residues, but issues and problems that arose during the testing process made it clear that greater value might be gained from the lessons that we learnt about methodology and the direction for future micro-residue research. We show that problems identified during our first tests stimulated research. Amongst other things, we learnt to distinguish plant and animal remains more confidently than previously. Our residue analyses are firmly embedded in wider archaeological research and our tests help to explain why there are sometimes contradictions between the evidence from archaeologically recovered remains and residues on stone tools. A further outcome of the tests is that we have adopted a multi-stranded approach that provides a cautious, but secure strategy for identifying and interpreting use-residues. Our studies of contaminants through replications have also been invaluable for distinguishing incidental residues from use-related residues.     

Global TransPark: New Competitiveness for Hong Kong and South China Based on Air Logistics

Economic globalization in the past two decades has led to a fast pace of growth of many economies in Asia Pacific, and impacted on the region's growth in air cargo. This paper discusses the future of airport infrastructure and its effect on regional competitiveness in the form of a new type of airport — Global TransPark (GTP). It identifies China's need to forge such a critical infrastructure in the New Economy, and that South China is its best location. The Hong Kong Extended Metropolitan Region (EMR) in South China stands out among competitive regions in Asia in terms of geopolitical and institutional setting under ‘One Country, Two Systems’ as the best general location for Asia's first and potentially largest GTP. Forging a GTP will promote the EMR's overall competitiveness and hastens its economic restructuring. The paper then discusses the advantages of Zhuhai Airport as the site of the potential GTP which will also incorporate the other four nearby airports within the EMR. The GTP is also a new challenge for intra-EMR cooperation in terms of customs and tariff, air rights, ground handling, and land and water transport coordination between its airports and respective local governments.     

Smoggy with a Chance of Altruism: The Effects of Ozone Alerts on Outdoor Recreation and Driving in Atlanta

Metropolitan smog alerts are prominent public information campaigns designed to enhance public health and to curb driving and other emissions. Unlike many other voluntary information‐based environmental policies, air quality alerts target household behavior via forecast information about ambient concentrations rather than firm or product characteristics. This paper explores behaviors with high emissions (driving) and with high exposure (outdoor recreation) and underscores the difference between altruistic and risk aversion motivations. Behavioral impacts are identified using the threshold nature of daily air quality forecasts. A regression discontinuity (RD) design finds elderly users and exercisers tend to curtail their use of a major park following smog alerts. The RD design also reveals that households do not drive less on smog alert days. Juxtaposing high emissions behavior with high exposure behavior in the same study highlights how public forecast information may better trigger some responses and struggle to trigger others.     

Restructuring Beijing's Social Space: Observations on the Olympic Games in 2008

Two American geographers comment on the preceding analysis of restructuring of Beijing's social space (Feng et al., 2007) by presenting observations on the city's Olympic Games, forthcoming in the summer of 2008. The authors focus on some of the more salient geographical impacts stemming from construction, relocation, and related measures undertaken by the authorities to accommodate the event. Included in the paper are sections on environmental concerns (particularly air pollution), infrastructure (water supply, automobile traffic, and mass transit), and relocation and displacement of residents (particularly of migrants and other disadvantaged segments of the population).

Localized mobility clusters: impacts of labour market externalities on firm performance

This article analyses the impact of labour market-induced externalitieson firm performance by using a unique database that connectsattributes of individuals to workplaces for the entire Swedisheconomy. Based on the analysis of 256,985 workplaces, our resultsshow that firms belonging to networks of local job mobility(i.e. ‘localized mobility clusters’) significantlyoutperform other similar firms within the local labour market.The results also indicate that concentrations of similar andrelated firms do not explain any considerable part of the variationsin firm competitiveness. Labour market externalities derivedvia local job mobility produce significantly more powerful effectsfor the involved firms as compared to the degree of co-location,diversity and scale.
