Torsten Hägerstrand
Torsten Hägerstrand (October 11, 1916, in Moheda – May 3, 2004, in Lund) was a Swedish geographer. He is known for his work on migration, cultural diffusion and time geography. A native and resident of Sweden, Hägerstrand was a professor (later professor emeritus) of geography at Lund University, where he received his doctorate in 1953. His doctoral research was on cultural diffusion. His research has helped to make Sweden, and particularly Lund, a major center of innovative work in cultural geography. He also influenced the practice of spatial planning in Sweden through his students. Early life Hägerstrand's father was a teacher at a remote elementary school and the family lived at the school. Hägerstrand recalled that his early education was based on the pedagogical ideas of Swiss educator Johann Pestalozzi. Several of Hägerstrand's students speculated that his holistic and visionary thinking was rooted in his early education: He was taught local geography, history ...

Cultural Geography
Cultural geography is a subfield within human geography. Though the first traces of the study of different nations and cultures on Earth can be dated back to ancient geographers such as Ptolemy or Strabo, cultural geography as academic study firstly emerged as an alternative to the Environmental determinism, environmental determinist theories of the early 20th century, which had believed that people and societies are controlled by the Natural environment, environment in which they develop.Peet, Richard; 1990; Modern Geographical Thought; Blackwell Rather than studying predetermined regions based upon environmental classifications, cultural geography became interested in cultural landscapes. This was led by the "father of cultural geography" Carl O. Sauer of the University of California, Berkeley. As a result, cultural geography was long dominated by United States, American writers. Geographers drawing on this tradition see cultures and societies as developing out of their local l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henri Lefebvre
Henri Lefebvre ( ; ; 16 June 1901 – 29 June 1991) was a French Marxist philosopher and sociologist, best known for furthering the critique of everyday life, for introducing the concepts of the right to the city and the production of social space, and for his work on dialectical materialism, alienation, and criticism of Stalinism, existentialism, and structuralism. In his prolific career, Lefebvre wrote more than sixty books and three hundred articles. He founded or took part in the founding of several intellectual and academic journals such as ''Philosophies'', ''La Revue Marxiste'', ''Arguments'', ''Socialisme ou Barbarie'', and ''Espaces et Sociétés''. Biography Lefebvre was born in Hagetmau, Landes, France. He studied philosophy at the University of Paris (the Sorbonne), graduating in 1920. By 1924 he was working with Paul Nizan, Norbert Guterman, Georges Friedmann, Georges Politzer, and Pierre Morhange in the ''Philosophies'' group seeking a "philosophical rev ...

Diffusion Of Innovations
Diffusion of innovations is a theory that seeks to explain how, why, and at what rate new ideas and technology spread. The theory was popularized by Everett Rogers in his book ''Diffusion of Innovations'', first published in 1962. Rogers argues that diffusion is the process by which an innovation is communicated through certain channels over time among the participants in a social system. The origins of the diffusion of innovations theory are varied and span multiple disciplines. Rogers proposes that five main elements influence the spread of a new idea: the innovation itself, adopters, communication channels, time, and a social system. This process relies heavily on social capital. The innovation must be widely adopted in order to self-sustain. Within the rate of adoption, there is a point at which an innovation reaches critical mass. In 1989, management consultants working at the consulting firm Regis McKenna, Inc. theorized that this point lies at the boundary between the ...

Time
Time is the continuous progression of existence that occurs in an apparently irreversible process, irreversible succession from the past, through the present, and into the future. It is a component quantity of various measurements used to sequence events, to compare the duration of events (or the intervals between them), and to quantify rates of change of quantities in material reality or in the qualia, conscious experience. Time is often referred to as a fourth dimension, along with Three-dimensional space, three spatial dimensions. Time is one of the seven fundamental physical quantities in both the International System of Units (SI) and International System of Quantities. The SI base unit of time is the second, which is defined by measuring the electronic transition frequency of caesium atoms. General relativity is the primary framework for understanding how spacetime works. Through advances in both theoretical and experimental investigations of spacetime, it has been shown ...

Space
Space is a three-dimensional continuum containing positions and directions. In classical physics, physical space is often conceived in three linear dimensions. Modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as '' spacetime''. The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework. In the 19th and 20th centuries mathematicians began to examine geometries that are non-Euclidean, in which space is conceived as '' curved'', rather than '' flat'', as in the Euclidean space. According to Albert Einstein's theory of general relativity, space around gravitational fields deviates from Euclidean space. Experimental tests of general relativity have confirmed that non-Euclidean geometries provide a bet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Copenhagen
Copenhagen ( ) is the capital and most populous city of Denmark, with a population of 1.4 million in the Urban area of Copenhagen, urban area. The city is situated on the islands of Zealand and Amager, separated from Malmö, Sweden, by the Øresund strait. The Øresund Bridge connects the two cities by rail and road. Originally a Vikings, Viking fishing village established in the 10th century in the vicinity of what is now Gammel Strand, Copenhagen became the capital of Denmark in the early 15th century. During the 16th century, the city served as the ''de facto'' capital of the Kalmar Union and the seat of the Union's monarchy, which governed most of the modern-day Nordic countries, Nordic region as part of a Danish confederation with Sweden and Norway. The city flourished as the cultural and economic centre of Scandinavia during the Renaissance. By the 17th century, it had become a regional centre of power, serving as the heart of the Danish government and Military history ...

Topics in regional science include, but are not limited to location theory or spatial eco .... Origins In the late 1940s and the early 1950s, the economist Walter Isard worked to draw together a group of academics interested in analyzing regional (i.e., sub-national) development. These academics were drawn from a number of disciplines: economics, geography, city planning, political science and rural sociology. Naming their new approach ''regional science'', they envisioned it as an interdisciplinary effort, one that would require unique theoretical concepts, methodological tools, and data. Because their effort was interdisciplinary, no existing academic organization brought the participants ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SMIL (computer)
SMIL (, "The Number Machine in Lund") was a History of computing hardware, first-generation computer built at Lund University in Lund, Sweden. SMIL was based on the IAS machine, IAS architecture developed by John von Neumann. :sv:Carl-Erik Fröberg, Carl-Erik Fröberg belonged to the group of five young Swedish scientists 1947–48 that IVA sent to the U.S. to gather information about the early computer development, and then came to strongly influence the development in Sweden. Fröberg visited with Erik Stemme the Institute for Advanced Study, and John von Neumann's research group. Back in Lund, he played a leading role in the creation of SMIL, which was the first computer developed in Lund and among the first in Sweden. SMIL was introduced in 1956 and then was in operation until 1970. In February 1962 SMIL was fitted with a compiler for ALGOL 60. The compiler was constructed by Torgil Ekman and Leif Robertson. Carl-Erik Fröberg was also behind the early emergence of numerical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Demography
Demography () is the statistical study of human populations: their size, composition (e.g., ethnic group, age), and how they change through the interplay of fertility (births), mortality (deaths), and migration. Demographic analysis examines and measures the dimensions and dynamics of populations; it can cover whole societies or groups defined by criteria such as education, nationality, religion, and ethnicity. Educational institutions usually treat demography as a field of sociology, though there are a number of independent demography departments. These methods have primarily been developed to study human populations, but are extended to a variety of areas where researchers want to know how populations of social actors can change across time through processes of birth, death, and migration. In the context of human biological populations, demographic analysis uses administrative records to develop an independent estimate of the population. Demographic analysis estima ...

Simulation
A simulation is an imitative representation of a process or system that could exist in the real world. In this broad sense, simulation can often be used interchangeably with model. Sometimes a clear distinction between the two terms is made, in which simulations require the use of models; the model represents the key characteristics or behaviors of the selected system or process, whereas the simulation represents the evolution of the model over time. Another way to distinguish between the terms is to define simulation as experimentation with the help of a model. This definition includes time-independent simulations. Often, computer simulation, computers are used to execute the simulation. Simulation is used in many contexts, such as simulation of technology for performance tuning or optimizing, safety engineering, testing, training, education, and video games. Simulation is also used with scientific modelling of natural systems or human systems to gain insight into their functio ...
