Abstract Which are the factors underlying human information production on a global level? In order to gain an insight into this question we study a corpus of 252–633 mil. publicly available data files on the Internet corresponding to an overall storage volume of 284–675 Terabytes. Analyzing the file size distribution for several distinct data types we find indications that the neuropsychological capacity of the human brain to process and record information may constitute the dominant limiting… Expand
Power laws and Self-Organized Criticality in Theory and Nature
TLDR
A comparative overview regarding distinct modeling approaches is presented together with a discussion of their potential relevance as underlying generative models for real-world phenomena. Expand
A large-scale study of the world wide web: network correlation functions with scale-invariant boundaries
TLDR
A study of the correlations found between quantities measuring the structural relevance of each node in the network, finding that some of these properties show strong correlation effects and that the dependencies occurring out of these correlations follow power laws not only for the averages, but also for the boundaries of the respective density distributions. Expand
Lognormal distributions of user post lengths in Internet discussions - a consequence of the Weber-Fechner law?
TLDR
It is suggested that the observed lognormal dependence may be due to an entropy maximizing combination of two psychological factors which are perceived on a non-linear, logarithmic scale in accordance with the Weber-Fechner law. Expand
Pushing the Complexity Barrier: Diminishing Returns in the Sciences
  • C. Gros
  • Economics, Computer Science
  • Complex Syst.
  • 2012
TLDR
It is argued that the outcome of science and technology funding in terms of measurable results is a highly sub-linear function of the amount of resources committed and supporting a range of small to medium size research projects will be a more efficient use of resources for science funding agencies. Expand
Design and Performance Evaluation of Data Dissemination Systems for Opportunistic Networks Based on Cognitive Heuristics
TLDR
Results show that the proposed solution is as effective as state-of-the-art solutions for data dissemination in opportunistic networks, while requiring far less resources. Expand
Information in the Biosphere: Biological and Digital Worlds.
TLDR
It is argued that the carbon-based biosphere has generated a cognitive system (humans) capable of creating technology that will result in a comparable evolutionary transition, like previous evolutionary transitions. Expand
Five decades of US, UK, German and Dutch music charts show that cultural processes are accelerating
TLDR
It is suggested that the fading relevance of personal time horizons may be causing an acceleration of cultural processes and that opinion dynamics may accelerate not only in cultural domains, but also in other settings, in particular in politics, where it could have far reaching consequences. Expand
Universal size effects for populations in group-outcome decision-making problems.
TLDR
A phenomenological model of vote participation is proposed where abstention is related to the perceived link of an agent to the rest of the constituency and which reproduces quantitatively the observed data. Expand
Driven by Food: Modeling Geographic Choice
TLDR
This work proposes a model in which an object is selected from a slate of candidates with probability that depends on how far it is (distance) and how many closer alternatives exist (rank), and shows that a four-parameter model based on combinations of lognormals has excellent performance at predicting restaurant choice. Expand
Charting closed-loop collective cultural decisions: From book best sellers and music downloads to Twitter hashtags and Reddit comments
TLDR
It is found that charts based on the active production of items, like commenting, are more likely to be influenced by external factors, in particular by the 24 hour day-night cycle. Expand

Coding of Cognitive Magnitude Compressed Scaling of Numerical Information in the Primate Prefrontal Cortex
TLDR
Certain cognitive and perceptual/sensory representations share the same fundamental mechanisms and neural coding schemes, and nonlinear compression was observed during the acquisition phase of the task and maintained through the memory phase with no further compression. Expand
The neural basis of the Weber–Fechner law: a logarithmic mental number line
  • S. Dehaene
  • Medicine, Psychology
  • Trends in Cognitive Sciences
  • 2003
TLDR
In a recent article, Nieder and Miller demonstrate a neural correlate of Weber's law, and thus resolve a classical debate in psychophysics: the mental number line seems to be logarithmic rather than linear. Expand
Representation of the Quantity of Visual Items in the Primate Prefrontal Cortex
Deriving the quantity of items is an abstract form of categorization. To explore it, monkeys were trained to judge whether successive visual displays contained the same quantity of items. ManyExpand
Loss of self-control in intertemporal choice may be attributable to logarithmic time-perception.
TLDR
It is hypothesized that empirically-observed dynamical inconsistency in intertemporal choice may result from errors in the perception of time-duration and proposed that perception of temporal duration following Weber's law might explain the dynamical consistency. Expand
THE VISUAL DISCRIMINATION OF INTENSITY AND THE WEBER-FECHNER LAW
  • S. Hecht
  • Psychology, Medicine
  • The Journal of general physiology
  • 1924
TLDR
A series of data is presented, assembled from various sources, which proves that in the visual discrimination of intensity the threshold difference ΔI bears no constant relation to the intensity I, and shows unequivocally that as the intensity rises, the ratio first decreases and then increases.

A Brief History of Generative Models for Power Law and Lognormal Distributions
TLDR
A rich and long history is found of how lognormal distributions have arisen as a possible alternative to power law distributions across many fields, focusing on underlying generative models that lead to these distributions. Expand
A theory of power-law distributions in financial market fluctuations
TLDR
This model is based on the hypothesis that large movements in stock market activity arise from the trades of large participants, and explains certain striking empirical regularities that describe the relationship between large fluctuations in prices, trading volume and the number of trades. Expand
Power-Law Distributions in Empirical Data
TLDR
This work proposes a principled statistical framework for discerning and quantifying power-law behavior in empirical data by combining maximum-likelihood fitting methods with goodness-of-fit tests based on the Kolmogorov-Smirnov (KS) statistic and likelihood ratios. Expand
Experience versus talent shapes the structure of the Web
TLDR
The balancing act between experience and talent on the web allows newly introduced pages with novel and interesting content to grow quickly and surpass older pages, much like what the authors observe in high-mobility and meritocratic societies. Expand

TLDR
This primer has been developed with the aim of conveying a wide range of "commons-sense" knowledge in the field of quantitative complex system science at an introductory level, providing an entry point to this both fascinating and vitally important subject. Expand
