Tracking behavioural differences across chronotypes: A case study in Finland using Oura rings
Chandreyee Roy, Kunal Bhattacharya, Kimmo Kaski
Non-invasive mobile wearables like fitness trackers, smartwatches and rings allow for an easier and relatively less expensive approach to study everyday human behaviour when compar…
Residential clustering and mobility of ethnic groups
Kunal Bhattacharya, Chandreyee Roy, Tuomas Takko +2
We studied residential clustering and mobility of ethnic minorities using a theoretical framework based on null models of spatial distributions and movements of populations. Using…
Modelling exposure between populations using networks of mobility during Covid-19
Tuomas Takko, Kunal Bhattacharya, Kimmo Kaski
The use of mobile phone call detail records and device location data for the calling patterns, movements, and social contacts of individuals, has proven to be valuable for devising…
Turnover in close friendships: age and gender differences
Chandreyee Roy, Kunal Bhattacharya, Robin I. M. Dunbar +1
Humans are social animals and the interpersonal bonds formed between them are crucial for their development and well being in a society. These relationships are usually structured…
Knowledge mining of unstructured information: application to cyber-domain
Tuomas Takko, Kunal Bhattacharya, Martti Lehto +3
Information on cyber-related crimes, incidents, and conflicts is abundantly available in numerous open online sources. However, processing the large volumes and streams of data is…
Human-agent coordination in a group formation game
Tuomas Takko, Kunal Bhattacharya, Daniel Monsivais +1
Coordination and cooperation between humans and autonomous agents in cooperative games raises interesting questions of human decision making and behaviour changes. Here we report o…
Internal migration and mobile communication patterns among pairs with strong ties
Mikaela Irene D. Fudolig, Daniel Monsivais, Kunal Bhattacharya +2
Using large-scale call detail records of anonymised mobile phone service subscribers with demographic and location information, we investigate how a long-distance residential move…
Dynamical properties of hierarchical networks of Van Der Pol oscillators
Daniel Monsivais, Kunal Bhattacharya, Rafael A. Barrio +2
Oscillator networks found in social and biological systems are characterized by the presence of wide ranges of coupling strengths and complex organization. Yet robustness and synch…
Link-centric analysis of variation by demographics in mobile phone communication patterns
Mikaela Irene D. Fudolig, Kunal Bhattacharya, Daniel Monsivais +2
We present a link-centric approach to study variation in the mobile phone communication patterns of individuals. Unlike most previous research on call detail records that focused o…
Different patterns of social closeness observed in mobile phone communication
Mikaela Irene D. Fudolig, Daniel Monsivais, Kunal Bhattacharya +2
We analyze a large-scale mobile phone call dataset containing information on the age, gender, and billing locality of users to get insight into social closeness in pairs of individ…
Social Physics: Uncovering Human Behaviour from Communication
Kunal Bhattacharya, Kimmo Kaski
In the post year 2000 era the technologies that facilitate human communication have rapidly multiplied. While the adoption of these technologies has hugely impacted the behaviour a…
Group formation on a small-world: experiment and modelling
Kunal Bhattacharya, Tuomas Takko, Daniel Monsivais +1
As a step towards studying human-agent collectives we conduct an online game with human participants cooperating on a network. The game is presented in the context of achieving gro…
Peer relations with mobile phone data: Best friends and family formation
Tamas David-Barrett, Anna Rotkirch, Asim Ghosh +5
Earlier attempts to investigate the changes of the role of friendship in different life stages have failed due to lack of data. We close this gap by using a large data set of mobil…
Network of families in a contemporary population: regional and cultural assortativity
Kunal Bhattacharya, Venla Berg, Asim Ghosh +4
Using a large dataset with individual-level demographic information of 60,000 families in contemporary Finland, we analyse the variation and cultural assortativity in a network of…
Migration patterns across the life course of families: Gender differences and proximity with parents and siblings in Finland
Asim Ghosh, Venla Berg, Kunal Bhattacharya +4
Family members' life course tendencies to remain geographically close to each other or to migrate due to education or job opportunities have been studied relatively little. Here we…
Tracking Urban Human Activity from Mobile Phone Calling Patterns
Daniel Monsivais, Asim Ghosh, Kunal Bhattacharya +2
Timings of human activities are marked by circadian clocks which in turn are entrained to different environmental signals. In an urban environment the presence of artificial lighti…
Quantifying gender preferences across humans lifespan
Asim Ghosh, Daniel Monsivais, Kunal Bhattacharya +2
In human relations individuals' gender and age play a key role in the structures and dynamics of their social arrangements. In order to analyze the gender preferences of individual…
Absence makes the heart grow fonder: social compensation when failure to interact risks weakening a relationship
Kunal Bhattacharya, Asim Ghosh, Daniel Monsivais +2
Social networks require active relationship maintenance if they are to be kept at a constant level of emotional closeness. For primates, including humans, failure to interact leads…
Seasonal and geographical impact on human resting periods
Daniel Monsivais, Kunal Bhattacharya, Asim Ghosh +2
We study the influence of seasonally and geographically related daily dynamics of daylight and ambient temperature on human resting or sleeping patterns using mobile phone data of…
Communication with family and friends across the life course
Tamas David-Barrett, Janos Kertesz, Anna Rotkirch +4
Each stage of the human life course is characterized by a distinctive pattern of social relations. We study how the intensity and importance of the closest social contacts vary acr…
Sex differences in social focus across the lifecycle in humans
Kunal Bhattacharya, Asim Ghosh, Daniel Monsivais +2
Age and gender are two important factors that play crucial roles in the way organisms allocate their social effort. In this study, we analyse a large mobile phone dataset to explor…
Flocking at the edge of chaos
Kunal Bhattacharya, Abhijit Chakraborty
Recent investigations have provided important insights into the complex structure and dynamics of collectively moving flocks of living organisms. Two intriguing observations are, s…
