Environment and Planning A: Economy and Space

Are people living in greener areas healthier than people living in less green areas? This hypothesis was empirically tested by combining Dutch data on the self-reported health of over 10 000 people with land-use data on the amount of greenspace in their living environment. In the multilevel analysis we controlled for socioeconomic and demographic characteristics, as well as urbanity. Living in a green environment was positively related to all three available health indicators, even stronger than urbanity at the municipal level. Analyses on subgroups showed that the relationship between greenspace and one of the health indicators was somewhat stronger for housewives and the elderly, two groups that are assumed to be more dependent on, and therefore exposed to, the local environment. Furthermore, for all three health indicators the relationship with greenspace was somewhat stronger for lower educated people. Implications for policymaking and spatial planning are discussed briefly.

The availability of choice is a neglected aspect in studies of geographical accessibility, which typically concentrate on distance to the nearest service. Records of patient registrations with general medical practices offer the opportunity to examine the geographical distribution of choice for an essential service. This population study of two million residents of Cambridgeshire, Norfolk, and Suffolk used postcodes extracted from patient registers and estimated car travel times from residential locations to general practice surgeries in a geographic information system. Only 56% of the population were registered with the practice nearest their home. People were more likely to use the nearest practice if they lived in rural rather than urban areas and where a surgery was within walking distance. Choice, as measured by the number of practices used by 95% of residents, was highest in the larger urban areas and lowest in small towns and rural areas with a local surgery. Ten percent of the population were served by monopoly practices. Overall, the distribution of registrations reflected a regular and predictable substitution of choice for increased travel time. People were 29% less likely to register with a practice for every additional minute of travel time: an almost perfect distance-decay relationship that was used to calibrate a potential model of accessibility over the study area. The resulting values of potential accessibility were found to approximate the combination of travel time to the nearest surgery and the actual range of choice exercised by residents. This demonstration that the potential accessibility model reflects consumer behaviour has applications beyond the health field.

Mobility is a key concept within recent social theorising on globalisation, transnationalisation of social relations, and new divisions of society. Mobility growth is also central to issues of global warming and the need for sustainable development. The aim of this paper is to elucidate empirically some properties of recent developments in international mobility. A theoretically informed understanding of changing patterns of long-distance travel is briefly outlined. This understanding is confronted with empirical findings concerning the actual development of international travel from Sweden during the 1990s. The findings confirm expected trends of further increasing intensity, extensity, and velocity in long-distance mobility. A tendency towards globalisation is observed, though an intraregional transnationalisation is the dominant process at work. It is concluded that an increasing short-term flexibilisation in people's use of time and space is a more important driving force behind the transnationalisation of mobility, than is the geographical extension of more enduring social relations. Influencing factors behind the social division of mobility are addressed by identifying the hypermobile segment of the population. Implications for the wider issues of globalisation and environmental sustainability are discussed.

This paper focuses on the parameterized-ordered weighted averaging (OWA) method. OWA is a family of multicriteria evaluation (or combination) rules. The proposed approach uses a parameter that serves as a mechanism for guiding multicriteria evaluation procedures. The parameter is incorporated into a method for obtaining the optimal order weights and for developing a transformation function. The function provides us with a consistent way of modifying the criterion values so that the multicriteria combination procedures can be guided by specifying a single parameter. The parameterized-OWA method has been implemented in a GIS environment as a GIS–OWA module and it has been tested in a real-world situation for developing management strategies in the Cedar Creek watershed in Ontario, Canada. Given a set of evaluation criteria, the problem is to evaluate areas in the watershed for rehabilitation and enhancement projects. Using the GIS–OWA method, a number of alternative strategies for rehabilitation and enhancement projects have been generated and evaluated.

In this paper we attempt to assess the changes in the Turkish production structure, and labor income in particular, between the 1970s and the 1990s. During this period a shift has taken place from an inward-looking policy towards an outward-oriented one. For our analysis we use two partially closed (or extended) input–output models. The demand-driven model is traditional for this type of analysis and examines the effects of a demand pull (for example, an increase in exports). For an open economy, however, it is not only important to investigate the effects of a demand pull, but also to examine how a cost push (for example, an increase in import prices) affects total gross output, value added, or labor income, for example. To study the effects of a cost push we introduce the partially closed supply-driven input–output model. Instead of analyzing the effects of a specific exogenous demand pull or cost push, we focus on various types of multiplier.

The ability of firms, industries, and regions continually to translate information and knowledge into viable new products, services, and production processes in the face of constantly changing technology and market conditions is increasingly at the core of competitive success in the contemporary economy. Such economic learning is ultimately dependent on the ability of individuals to learn, and yet most of the literature in this area has focused on firms and organizational learning processes, and is only beginning to engage seriously with people's learning processes. This paper explores the links between social learning processes and dynamics of innovation in Silicon Valley, arguing that cross-firm, occupationally based, ‘communities of practice’ provide a critical context for individuals to learn and maintain the competencies they need to be successful in the region's dynamic but volatile economy. These cross-firm occupational learning communities in many cases are being built through the activities of formal professional associations, which are playing an increasingly important role in providing the organizational infrastructure to sustain these learning communities. Using a case study of an association of women in Internet design and development occupations, the author illustrates the value of such communities in supporting individual and collective learning processes. These findings suggest that economic development strategies could productively be focused on identifying, strengthening, and expanding access to such cross-firm occupational learning communities.

Adopting a focus on both time and space, the authors aim to unpack the complexity of uses and users in the city centre. Evidence from Swansea reveals a stark twofold temporal division between a frequently visited daytime city and a much less frequently visited evening and nighttime city. Furthermore, lower intensity evening activities such as theatres and cinemas are distinguished from the higher intensity nighttime activities of pubs and clubs, with restaurants and cafés occupying an intermediate position. The evening clientele visit less frequently and are disproportionately drawn from the older and higher status social groups, whereas later at night, pubs and clubs are visited more frequently, and by imbalances of the young, lower status groups, and students. The city centre is seen as an area of spatial, temporal, and social segregation, with implications for policies that aim towards a more inclusive and safer 24-hour city. The conclusions emphasise the importance of time in urban geographical research and in policies for city-centre revitalisation.

The reform of regional governance in the United Kingdom has been, in part, premised on the notion that regions provide new territories of action in which cooperative networks between business communities and state agencies can be established. Promoting business interests is seen as one mechanism for enhancing the economic competitiveness and performance of ‘laggard’ regions. Yet, within this context of change, business agendas and capacities are often assumed to exist ‘out there’, as a resource waiting to be tapped by state institutions. There is little recognition that business organisations' involvement in networks of governance owes much to historical patterns and practices of business representation, to the types of activities that exist within the business sector, and to interpretations of their own role and position within wider policymaking and implementation networks. This paper, drawing on a study of business agendas in post-devolution Scotland, demonstrates that in practice business agendas are highly complex. Their formation in any particular place depends on the actions of reflexive agents, whose perspectives and capacities are shaped by the social, economic, and political contexts within which they are operating. As such, any understanding of business agendas needs to identify the social relations of business as a whole, rather than assuming away such complexities.

In this paper, I explore the manner in which, since the 1980s, some Turkish domestic firms in the clothing industry have found ways of connecting themselves to the global webs of manufacturing, distribution, and retailing of garments. I call attention to two related developments that have occurred during the process. First, a number of manufacturing firms have acquired enough autonomy to develop and exercise their own strategies, have upgraded their operations, and, as original brand-name manufacturers, have evolved into global competitors. Second, some large domestic manufacturers have experienced a cautious and gradual transformation from industrial capital to commercial and financial capital. The findings show the necessity of seeing firms as intentional agents of change with some autonomy of their own as well as the importance of maintaining a structural understanding of power relations in the networked relationships of the global economy.
