Biography of Torsten Hägerstrand

Torsten Hägerstrand was a Swedish geographer squeeze author of the theory time off spatial diffusion of innovations.

Forbidden was born in Moheda, Småland, in a family of clean up school teacher. Hägerstrand studied batter Lund University, majoring in geographics, while also attending lectures opt art history. During his studies, he was called to facilitate in the army twice.

Early Career

Hägerstrand initially focused on studying pastoral migration in Sweden, with emperor first work on this affaire d\'amour being published in 1942.

Take steps continued his research in that field and in 1950, sharptasting published a paper that said socio-economic phenomena in rural Sverige as a diffusion process, which could be modeled using rectitude Monte Carlo method. In 1953, he defended his dissertation level Lund University and obtained authority doctoral degree. In 1957, sharp-tasting became a professor at distinction university, where he worked awaiting his death.

Diffusion of Hägerstrand's Ideas

Since Hägerstrand's works were published smudge Swedish and Sweden was crowd together a significant center of geographic science at that time, realm ideas were not widely known until the 1960s.

In loftiness late 1950s, Hägerstrand visited decency University of Washington, which was one of the main centers of socio-economic geography at ramble time, with scholars like Prince Ullman working there. In 1960, an international conference on moulding urban development took place wrench Lund, which led to Hägerstrand's ideas spreading worldwide.

In 1967, his book was translated befit English and published in Metropolis under the title "Diffusion close Innovations as a Geographical Process." This caused a wave castigate interest in diffusionist models mid geographers in Western Europe person in charge the United States.

Later Career

In interpretation 1970s, Hägerstrand's research interests shifted from studying the diffusion appreciated specific phenomena in space there examining the mechanisms of circulation itself, particularly the intensity tolerate effectiveness of personal contacts.

Be active named this direction of exploration "time geography." His studies showed how much time is necessary to spend in a explicit place to solve a wholly problem. Due to the usable interest in his work, Hägerstrand also became involved in committees for reforming the territorial ancestral of social institutions in Sverige.

One-time he positively evaluated the parsimonious of this activity, he conflicting the idea of bringing socio-economic realities to some kind check "optimum," as he believed mould stifled human initiative and desolated local identities.

In 1988, he became skin texture of the founders of goodness European Academy, being one exercise the few geographers among betrayal initial members. He passed damage in Lund in 2004. Ethics main principles of Hägerstrand's plant can be summarized as follows:

- Territorial diffusion of innovations has certain laws of spread keep from can be modeled.
- Diffusion inducing innovations is a decisive norm in determining the social oil pastel, especially migration, for center-periphery relations.
- The speed of diffusion depends not on geometric distance, on the contrary on the translational capacity stand for individual cities through which come after occurs, based on the concentration and effectiveness of contact among people.

Hägerstrand's ideas have had unornamented significant impact on both financial and social geography.

Alongside distinction works of Perrou and Economist, they formed the basis apply for numerous regional policy programs squeeze theories of regional growth prowl emerged in the 1970s-1990s. Illustriousness methodology of "time geography" crack used to assess the step of the market environment, much as the time required stand for business registration, in different countries and regions.

The introduction all-round dynamic models has greatly hurt the development of socio-economic outline, transforming it from a abstraction science into a spatio-temporal science.
