This choice of contributed chapters demonstrates quite a lot of purposes inside of overlapping learn domain names: social media research and social community research. a number of methodologies have been used in the twelve person chapters together with static, dynamic and real-time ways to graph, textual and multimedia information research. the themes follow to popularity computation, emotion detection, subject evolution, rumor propagation, review of textual critiques, good friend score, research of public transportation networks, diffusion in dynamic networks, research of individuals to groups of open resource software program builders, biometric template iteration in addition to research of consumer habit inside heterogeneous environments of cultural academic facilities. Addressing those difficult functions is what makes this edited quantity of curiosity to researchers and scholars curious about social media and social community analysis.

The Gutenberg Galaxy: The Making of Typographic Man

This e-book popularised the phrases "global village" and "Gutenberg Galaxy".
McLuhan analysed the consequences of assorted conversation media and strategies on eu tradition and human consciousness.

McLuhan reports the emergence of what he calls "Gutenberg Man", the topic produced through the swap of realization wrought by way of the appearance of the published ebook. A propos of his axiom, "The medium is the message," McLuhan argues that applied sciences aren't easily innovations which individuals hire yet are the capacity through which everyone is re-invented. the discovery of movable sort used to be the decisive second within the switch from a tradition during which the entire senses partook of a typical interaction to a tyranny of the visible. He additionally argued that the improvement of the printing press ended in the construction of nationalism, dualism, domination of rationalism, automatisation of clinical learn, uniformation and standardisation of tradition and alienation of people. Movable variety, with its skill to breed texts adequately and quickly, prolonged the force towards homogeneity and repeatability already in facts within the emergence of perspectival artwork and the exigencies of the one "point of view".
He writes: the area of visible viewpoint is one among unified and homogeneous house. the sort of international is alien to the resonating range of spoken phrases. So language used to be the final paintings to just accept the visible common sense of Gutenberg know-how, and the 1st to rebound within the electrical age. (p. 136)

How We Think: Digital Media and Contemporary Technogenesis

“How will we imagine? ” N. Katherine Hayles poses this question initially of this bracing exploration of the concept that we expect via, with, and along media. because the age of print passes and new applied sciences look each day, this proposition has turn into way more complex, really for the regularly print-based disciplines within the humanities and qualitative social sciences.

Sample text

Many studies that involve social networks assume the second degrees (degrees of the neighbors) are known either because the degree distribution of agents contains high information. We are currently relaxing this assumption and trying to estimate the second degree distribution using bayesian probabilistic methods. We assume that each agent start the estimation with the same degree of its own [6]. The degree distribution of a given social network is assumed to follow a power-law distribution and we let each agent apply power-law to the estimated second degree distribution.

Most centrality measures in social network analysis research unfortunately consider only topological structure of the network and are oblivious of transportation factors. This paper proposes new centrality measures that incorporate travel time delay and commuter flow volume. We apply the proposed measures on the Singapore’s subway network involving 89 stations and about 2 million commuter trips per day, and compare them with traditional topology based centrality measures. Several interesting insights about the network are derived from the new measures.
