Directedness of Information Flow in Mobile Phone Communication Networks

Fernando Peruani, Lionel Tabourier, Petter Holme
2011 PLoS ONE  
Here, we study causality trees in mobile-phone data, which can be represented as a dynamical directed network.  ...  Without having direct access to the information that is being exchanged, traces of information flow can be obtained by looking at temporal sequences of user interactions.  ...  [5] studied flooding of information in a mobile phone network.  ...

How to detect causality effects on large dynamical communication networks: A case study

Lionel Tabourier, Alina Stoica, Fernando Peruani
2012 2012 Fourth International Conference on Communication Systems and Networks (COMSNETS 2012)  
This suggests that mobile phone networks are used almost exclusively to communicate information to a closed group of individuals.  ...  This approach is illustrated on a large cellphone call dataset: we show that specific patterns such as short chain-like trees and directed loops are more frequent in real networks than in comparison models  ...  Information spreading is strongly affected by the directedness of the underlying network and the temporal ordering of the communications.  ...

Emerging Network-Based Tools in Movement Ecology

David M.P. Jacoby, Robin Freeman
2016 Trends in Ecology & Evolution  
Refining how we 35 construct and randomise spatial networks at different temporal scales will help establish 36 network theory as a prominent, hypothesis-generating tool in movement ecology. 37  ...  Network analyses offer a powerful 30 suite of tools to disentangle the complexity within these dynamic systems and we review 31 these tools, their application, and how they have generated new ecological  ...  Farine and one anonymous reviewer for their helpful 337 feedback on earlier drafts of the manuscript.

Automatic Archiving versus Default Deletion: What Snapchat Tells Us About Ephemerality in Design

Bin Xu, Pamara Chang, Christopher L Welker, Natalya N Bazarova, Dan Cosley
2016 Proceedings of the 19th ACM Conference on Computer-Supported Cooperative Work & Social Computing - CSCW '16  
Further, although receivers can save content through screenshots, senders are notified; this selective saving with notification supports complex information norms that preserve the feel of ephemeral communication  ...  Along with friend-adding features that facilitate a network of mostly close relations, default deletion affords everyday, mundane talk and reduces self-consciousness while encouraging playful interaction  ...  ACKNOWLEDGMENTS This work is supported in part by the National Science Foundation (IIS-0910664 and IIS-1405634).  ...

Network epidemiology and plant trade networks

Marco Pautasso, Mike J. Jeger
2014 AoB Plants  
Human (and plant) mobility levels across the planet are unprecedented-there is thus much potential in the use of network theory by plant health authorities and researchers.  ...  Recent surveys have provided much-needed datasets on contact patterns and human mobility in social networks, but plant trade networks are still understudied.  ...  Human mobility data are being obtained from various sources, from consecutive sightings of banknotes to mobile phone records.  ...

Behavioral Aspects of Urban Resilience

2013 Innovation and Supply Chain Management  
Especially in emergency situations, e.g. during or in the aftermath of extreme events, simple decision making rules replace careful and rational assessment of different choice alternatives.  ...  In order to close this gap, we review relevant insights on human decision making and collective dynamics, and propose a framework for studying behavioral aspects in the context of urban resilience.  ...  Acknowledgments This is a majorly revised and extended version of a conference paper presented at the 2013 IEEE Conference on Dependable Systems and Networks in Budapest [62] .  ...

What's wrong with globalization?: Contra 'flow speak' - towards an existential turn in the theory of globalization

Heinz Bude, Jörg Dürrschmidt
2010 European Journal of Social Theory  
We identify 'flow speak' and the flattened ontology of the social that goes with it as a major limitation in contemporary globalization theory.  ...  Contrary to the prevailing overemphasis on mobility and deterritorialization, we suggest an existential turn that orients future globalization thinking more towards issues of belonging, choice and commitment  ...  -mobility of goods and commodities, mobility of information and communication products and services, and mobility of people. 484 European Journal of Social Theory 13(4) We are being told that the paradigmatic  ...

Even after decades spent in a destination country, Muslim population remains poorly integrated in the local community and its impact on the latter is insignificant (e. g. Turks in Germany).  ...  Migration flows differ significantly by country and EU region.  ...  Apparently, key importance in this case is placed on modern means of information and communication (social networks, mobile communication).  ...

Five days without a smartphone. Smartphone use and subjective well-being: Results from a study comparing normal use with a deprivation condition

Susann Kohout, Christina Schumann
2020 SCM. Studies in Communication and Media  
However, results from the deprivation part of the study indicate that in sum, satisfaction with social relations clearly worsened when not using a smartphone.  ...  Regular smartphone use is studied in various situations and for different functions.  ...  Deprivation prevents people from being constantly connected and it appears that not being part of the normal communication flow in a social network evokes feelings of isolation.  ...

Cognitive-Costed Agent Model of the Microblogging Network [chapter]

Mitsuhiro Nakamura, Hiroshi Deguchi
2011 Agent-Based Approaches in Economic and Social Complex Systems VI  
Microblogging is a new paradigm spreading in social web services that provides us a light-weight, speedy way of communication.  ...  We find that the network structure in Twitter has two main features: link reciprocity and asymmetricity between distributions of the in-degree and out-degree.  ...  Users can communicate and share information in the blink of an eye. Furthermore, they can add the other users as their friends therefore the microblogging system is a class of social networks.  ...
