Turning crowds into communities: The collectives of online citizen science

Over the past two decades, a number of digital platforms have been developed with the aim of engaging citizens in scientific research projects. The success of these platforms depends in no small part on their ability to attract and retain participants, tur ...

Crowd Dynamics and Crowd Capital in Small Teams: Insights from three crowdsourcing exercises in higher education

Christopher Tucci, Gianluigi Viscusi

In this work we aim to study “crowd” dynamics in small teams. To this end, we use the typology of crowds discussed in Viscusi and Tucci [2015] as an interpretive framework, arguing that other characteristics are relevant to identify crowds than the number ...

Three Essays on Collective Forms of Organizing for Production and Innovation

Joana Rodrigues Pereira

This dissertation focuses on collective forms or organizing that through crowds or communities undertake production or innovation activities. Such organizations deviate from the traditional notions of hierarchy, authority, and control; however, they are st ...

“What’s the frequency, Kenneth?” Defining the crowd organization

Christopher Tucci, Gianluigi Viscusi, Joana Rodrigues Pereira

In this paper, we provide guidelines for strategically using crowds as part of a crowdsourcing strategy and an open innovation portfolio. We start by defining crowd organisations as sustained through a crowd of loosely coupled and equally aligned agents th ...

Control of agent swarms in random environments

Guillaume Adrien Sartoretti

The collective dynamic behavior of large groups of interacting autonomous agents (swarms) have inspired much research in both fundamental and engineering sciences. It is now widely acknowledged that the intrinsic nonlinearities due to mutual interactions c ...

Mechanosensory interactions drive collective behaviour in Drosophila

Dario Floreano, Pavan P Ramdya, Pawel Lichocki, Lukas Frisch, Winnie Wing Yee Tse

Collective behaviour enhances environmental sensing and decision-making in groups of animals. Experimental and theoretical investigations of schooling fish, flocking birds and human crowds have demonstrated that simple interactions between individuals can ...

Queue Profile Estimation in Congested Urban Networks with Probe Data

Nikolaos Geroliminis, Mohsen Ramezani Ghalenoei

Queues at signalized intersections are the main cause of traffic delays and travel time variability in urban networks. In this article, we propose a method to estimate queue profiles that are traffic shockwave polygons in the time-space plane describing th ...
