Using network properties to predict disease dynamics on human contact networks

October 28, 2011 Comments (0)

We show that although degree distribution is sufficient to predict disease behaviour on very sparse or very dense human contact networks, for intermediate density networks we must include information on clustering and path length to accurately predict disease behaviour. Using these three metrics, we were able to explain more than 98 per cent of the variation in endemic disease levels in our...

Assessing Vaccination Sentiments with Online Social Media: Implications for Infectious Disease Dynamics and Control

October 28, 2011 Comments (0)

Sentiments about vaccination can strongly affect individual vaccination decisions. Measuring such sentiments - and how they are distributed in a population - is typically a difficult and resource-intensive endeavor. We use publicly available data from Twitter, a popular online social media service, to measure the evolution and distribution of sentiments towards the novel influenza A(H1N1) vaccine...

The complexification of engineering

October 28, 2011 Comments (0)

This paper deals with the arrow of complexification of engineering. We claim that the complexification of engineering consists in (a) that shift throughout which engineering becomes a science; thus it ceases to be a (mere) praxis or profession; (b) becoming a science, engineering can be considered as one of the sciences of complexity. In reality, the complexification of engineering is the process...

Self-similar scaling of density in complex real-world networks

October 28, 2011 Comments (0)

Despite their diverse origin, networks of large real-world systems reveal a number of common properties including small-world phenomena, scale-free degree distributions and modularity. Recently, network self-similarity as a natural outcome of the evolution of real-world systems has also attracted much attention within the physics literature. Here we investigate the scaling of density in complex...

Would you follow your own route description? Cognitive strategies in urban route planning

October 28, 2011 Comments (0)

► We address route choice and planning strategies in familiar urban Environments. ► Verbal and behavioral data reflect differences between planning Situations. ► En-route planning is direction-based; in-advance planning based on salient streets. ► Strategy choice is highly adaptive, influenced by perceptual information available. ► Route directions and planned routes are furthermore...

Social dynamics with peer support on heterogeneous networks

October 28, 2011 Comments (0)

Human behavior often exhibits a scheme in which individuals adopt indifferent, neutral, or radical positions on a given topic. The mechanisms leading to community formation are strongly related with social pressure and the topology of the contact network. Here, we discuss an approach to model social behavior which accounts for the protection by alike peers proportional to their relative abundance...

Communication activity in social networks: growth and correlations

October 28, 2011 Comments (0)

We investigate the timing of messages sent in two online communities with respect to growth fluctuations and long-term correlations. We find that the timing of sending and receiving messages comprises pronounced long-term persistence. Considering the activity of the community members as growing entities, i.e. the cumulative number of messages sent (or received) by the individuals, we identify...

The Structure of Complex Networks: Theory and Applications

October 28, 2011 Comments (0)

This book deals with the analysis of the structure of complex networks by combining results from graph theory, physics, and pattern recognition. The book is divided into two parts. 11 chapters are dedicated to the development of theoretical tools for the structural analysis of networks, and 7 chapters are illustrating, in a critical way, applications of these tools to real-world scenarios....

The Folly of Fools: The Logic of Deceit and Self-Deception in Human Life

October 28, 2011 Comments (0)

Whether it's the planning of an offensive war, a romantic relationship or an office dispute, there are many opportunities to lie and self-deceive, but deceit and self-deception carry the costs of being alienated from reality and can lead to disaster. So why does deception play such a prominent role in our everyday lives? In short, why do we deceive? In his bold new work, prominent...

Thinking, Fast and Slow

October 28, 2011 Comments (0)

Daniel Kahneman, recipient of the Nobel Prize in Economic Sciences for his seminal work in psychology that challenged the rational model of judgment and decision making, takes us on a groundbreaking tour of the mind and explains the two systems that drive the way we think. System 1 is fast, intuitive, and emotional; System 2 is slower, more deliberative, and more logical. Kahneman exposes...
