Urban magnetism through the lens of geo-tagged photography
Springer Science and Business Media LLC - Tập 4 - Trang 1-17 - 2015
Silvia Paldino, Iva Bojic, Stanislav Sobolevsky, Carlo Ratti, Marta C González
There is an increasing trend of people leaving digital traces through social media. This reality opens new horizons for urban studies. With this kind of data, researchers and urban planners can detect many aspects of how people live in cities and can also suggest how to transform cities into more efficient and smarter places to live in. In particular, their digital trails can be used to investigat...... hiện toàn bộ
Rapid rise and decay in petition signing
Springer Science and Business Media LLC - - 2017
Taha Yasseri, Scott A Hale, Helen Z Margetts
Contemporary collective action, much of which involves social media and other Internet-based platforms, leaves a digital imprint which may be harvested to better understand the dynamics of mobilization. Petition signing is an example of collective action which has gained in popularity with rising use of social media and provides such data for the whole population of petition signatories for a give...... hiện toàn bộ

Sustainability of Stack Exchange Q&A communities: the role of trust
Springer Science and Business Media LLC - Tập 12 - Trang 1-24 - 2023
Ana Vranić, Aleksandar Tomašević, Aleksandra Alorić, Marija Mitrović Dankulov
Knowledge-sharing communities are fundamental elements of a knowledge-based society. Understanding how different factors influence their sustainability is of crucial importance. We explore the role of the social network structure and social trust in their sustainability. We analyze the early evolution of social networks in four pairs of active and closed Stack Exchange communities on topics of phy...... hiện toàn bộ
Using wearable proximity sensors to characterize social contact patterns in a village of rural Malawi
Springer Science and Business Media LLC - Tập 10 Số 1 - 2021
Laura Ozella, Daniela Paolotti, Guilherme Lichand, Jorge Rodríguez, Simon Haenni, John Phuka, Onício Leal Neto, Ciro Cattuto
AbstractMeasuring close proximity interactions between individuals can provide key information on social contacts in human communities and related behaviours. This is even more essential in rural settings in low- and middle-income countries where there is a need to understand contact patterns for the implementation of strategies for social protection interventions....... hiện toàn bộ
Multiple gravity laws for human mobility within cities
Springer Science and Business Media LLC - Tập 12 - Trang 1-12 - 2023
Oh-Hyun Kwon, Inho Hong, Woo-Sung Jung, Hang-Hyun Jo
The gravity model of human mobility has successfully described the deterrence of travels with distance in urban mobility patterns. While a broad spectrum of deterrence was found across different cities, yet it is not empirically clear if movement patterns in a single city could also have a spectrum of distance exponents denoting a varying deterrence depending on the origin and destination regions ...... hiện toàn bộ
Gravity law in the Chinese highway freight transportation networks
Springer Science and Business Media LLC - Tập 8 - Trang 1-28 - 2019
Li Wang, Jun-Chao Ma, Zhi-Qiang Jiang, Wanfeng Yan, Wei-Xing Zhou
The gravity law has been documented in many socioeconomic networks, which states that the flow between two nodes positively correlates with the strengths of the nodes and negatively correlates with the distance between the two nodes. However, such research on highway freight transportation networks (HFTNs) is rare. We construct the directed and undirected highway freight transportation networks be...... hiện toàn bộ
Fast filtering and animation of large dynamic networks
Springer Science and Business Media LLC - Tập 3 - Trang 1-16 - 2014
Przemyslaw A Grabowicz, Luca Maria Aiello, Filippo Menczer
Detecting and visualizing what are the most relevant changes in an evolving network is an open challenge in several domains. We present a fast algorithm that filters subsets of the strongest nodes and edges representing an evolving weighted graph and visualize it by either creating a movie, or by streaming it to an interactive network visualization tool. The algorithm is an approximation of expone...... hiện toàn bộ
Instagram photos reveal predictive markers of depression
Springer Science and Business Media LLC - Tập 6 - Trang 1-12 - 2017
Andrew G Reece, Christopher M Danforth
Using Instagram data from 166 individuals, we applied machine learning tools to successfully identify markers of depression. Statistical features were computationally extracted from 43,950 participant Instagram photos, using color analysis, metadata components, and algorithmic face detection. Resulting models outperformed general practitioners’ average unassisted diagnostic success rate for depres...... hiện toàn bộ
Responsible team players wanted: an analysis of soft skill requirements in job advertisements
Springer Science and Business Media LLC - Tập 8 - Trang 1-20 - 2019
Federica Calanca, Luiza Sayfullina, Lara Minkus, Claudia Wagner, Eric Malmi
During the past decades the importance of soft skills for labour market outcomes has grown substantially. This carries implications for labour market inequality, since previous research shows that soft skills are not valued equally across race and gender. This work explores the role of soft skills in job advertisements by drawing on methods from computational science as well as on theoretical and ...... hiện toàn bộ
