“The Diffusion of Scientific Knowledge Across Time and Space,” P. Azoulay, J.S. Graff Zivin, B.N. Sanpat () How important is it to be near “star” scientists. Theories in urban geography regularly suggest that face-to-face contact is critical for the spread of ideas – dense cities tend to be richer partly for this reason.

Book: Although the book once represented the primary mechanism for disseminating scientific knowledge, academics – especially those in the physical and biological sciences – have increasingly turned to journal articles as the preferred outlet for publishing research (Bazerman, ).

Moreover, books face varying standards for publication. Dominique Foray, Francesco Lissoni, in Handbook of the Economics of Innovation, On rewards, spillovers, and the distribution of IP. University and industry follow very different economic logic with respect to the relative importance of “appropriability” versus the benefits of full and costless knowledge diffusion.

Sampat Comment: Adam B. Jaffe. The series "Knowledge and Space" is dedicated to topics dealing with the production, application, spatial distribution and diffusion of knowledge.

Science Studies, Actor-Network Theory, research on learning organisations, studies on creative milieus, and the Geographies of Knowledge, Education and Science have all highlighted the importance of.

The sector- and region-specific capital stocks at time t + 1, J i r t + 1 are determined by (1) investments into new varieties in time t, (2) the size of the (beginning-of-period) knowledge stock in time t, and (3) the capital increment in time t due to knowledge diffusion, ΔJ irt: (14) J i r t + 1 = I i r t + (1 − δ t) (Δ J i r t + J i r.

1. Introduction. Every day, new knowledge is being created and published in the form of scientific articles. When knowledge is steadily increasing, it becomes difficult for new ideas to gain traction and to get noticed (Katz et al., ; Rogers, ).To navigate this complex and overloaded market of ideas, scientists often consider the citations that a publication receives.

1. Introduction. The innovation potential of modern economies rests strongly on the diffusion of knowledge (Romer, ; Audretsch and Feldman, ).Scientific and technological advances tend to follow cumulative trajectories where new results build on previous findings (Scotchmer ; Belenzon, ).Information disclosure is an important antecedent of diffusion and can be a.

“A model of its kind, Putting Science in Its Place is accessible and well written, yet packed with information and carrying a coherent and important message--that space does indeed play an important role in the constitution of knowledge. Livingstone provides a survey of the actual ways in which it does so, using deft historical examples and masterfully tying them together.

Knowledge diffusion can be defined as the adaptations and applications of knowledge documented in scientific publications and patents (Crane, ). Knowledge diffusion is part of the knowledge management process, realizing the proliferation of knowledge and information among different individuals across time and space (Chen & Hicks, ).

Society for the Diffusion of Useful Knowledge. Thomas Palmelund Johansen. By spreading cheap secular books and periodicals on "scientific" and "useful" knowledge, the Society and its numerous members sought to diffuse ideas about Western science and civilization, not only within the British Isles, but also all throughout the British Empire.

Research Policy 33 () – Science and the diffusion of knowledge Olav Sorensona,∗,1, Lee Flemingb,1 a Anderson Graduate School of Management, UCLA, Westwood Plaza, BoxLos Angeles, CAUSA b Harvard Business School, Boston, MAUSA Received 13 February ; received in revised form 8 September ; accepted 20 September This is a participatory and collaborative space where both Southern and Northern scholars will discuss issues, concepts and methods to produce knowledge and improve our understanding of policy diffusion and development cooperation.

Diffusion of innovations is a theory that seeks to explain how, why, and at what rate new ideas and technology spread. Everett Rogers, a professor of communication studies, popularized the theory in his book Diffusion of Innovations; the book was first published inand is now in its fifth edition ().

Rogers argues that diffusion is the process by which an innovation is communicated. How Diffusion Works. In diffusion, particles move down a concentration gradient. Diffusion is different from other transport processes in that it results in mixing without bulk matter flow.

How it works is that molecules in motion from thermal energy randomly move about. Over time, this "random walk" leads to uniform distribution of different.

Essential Knowledge: 2.B.2 Growth and dynamic homeostasis are maintained by the constant movement of molecules across membranes.: Science Practice: The student can use representations and models to analyze situations or solve problems qualitatively and quantitatively.: Science Practice: The student can pose scientific questions.: Learning Objective: The student is able to.

Indeed, the diffusion operator may degenerate as the solution diverges and may depend on space and time variables in a non–regular way, too. Some estimates on the behaviour of the solutions for. Diffusion, also known as cultural diffusion, is a social process through which elements of culture spread from one society or social group to another, which means it is, in essence, a process of social is also the process through which innovations are introduced into an organization or social group, sometimes called the diffusion of innovations.

Background. The use of knowledge (and science) for the betterment of society is an overarching theme in much of western thought. Knowledge plays such a central role in contemporary societies that they have become known as knowledge societies [1,2].Many facets of contemporary societies depend increasingly on science and technology [].Science is not, however, separate from society, and.

Diffusion, process resulting from random motion of molecules by which there is a net flow of matter from a region of high concentration to a region of low concentration. A familiar example is the perfume of a flower that quickly permeates the still air of a room. Ryan R. Brady, "Measuring the diffusion of housing prices across space and over time," Journal of Applied Econometrics, John Wiley & Sons, Ltd., vol.

26(2), pagesMarch. The article concludes that there is an open agenda in the fields of knowledge creation, diffusion, and utilization. Once some closure is reached on the measurement issues, then it should be possible to advance a systematic theory of knowledge production and utilization.

Hägerstrand as historian: innovation, diffusion and the processual landscape Sverker Sörlin Divison of History of Science, Technology and Environment, KTH Royal Institute of Technology, Stockholm, Sweden ABSTRACT Torsten Hägerstrand explored innovation and diffusion as chorological processes but also as chronological processes.

The Smithsonian Institution (/ s m ɪ θ ˈ s oʊ n i ə n / smith-SOH-nee-ən), also known simply as The Smithsonian, is a trust instrumentality of the United States composed as a group of museums and research centers.

It was founded on Aug"for the increase and diffusion of knowledge". The institution is named after its founding donor, British scientist James Smithson. Evolution of Knowledge Science: Myth to Medicine: Intelligent Internet-Based Humanist Machines explains how to design and build the next generation of intelligent machines that solve social and environmental problems in a systematic, coherent, and optimal fashion.

The book brings together principles from computer and communication sciences, electrical engineering, mathematics, physics. At the same time, it also illustrated the self-correcting nature of this knowledge space - with the underlying theory that believable truths will be born out and justified over time by the involvement of the entire community in building of the knowledge space, so in a .The widespread availability of paper encouraged an extraordinary culture of book-learning throughout the Muslim lands that was unparalleled in contemporary Christendom, which continued to rely on relatively expensive parchment, thereby restricting the number of writers and readers (Bloom, ).Nevertheless, cultural factors affected the diffusion of its manufacture over space and time.The concept of science includes both activity aimed at gaining new knowledge and the result of such activity—the sum of the scientific knowledge acquired up to a given time, which constitutes the scientific conception of the world.

The term “science” is also used to designate the various branches of scientific knowledge.
