2021 – Lyon

Coinciding with the Conference on Complex Systems, and profiting from the opportunity offered by the presence of a wide variety of experts in different topics, we are organising two-day school for PhD students and early-stage researchers. The school is an informal two-day event that offers early-stage scientists the opportunity to hear talks from prominent young researchers, learn about the scientific and life experience of young and senior researchers, socialise and have fun playing the specifically tailored online trivia.

This year, due to a worldwide pandemic situation, the school is going to be to be held in hybrid mode, both on-site and online, on October 22-23, 2021, before the main CCS conference. The preliminary school schedule consists of four lectures from young scientists, scientific writing workshop session, project-making event, pub quiz and social event on-site. The sessions will be divided by informal coffee breaks, where participants may chatter with their peers, both online and face-to-face.

Important details

The registration is finally open! Tickets are available here. The event will happen in hybrid format, therefore there are two modes for participation:

Complexity & Data Science for the SDGs

In a rapidly changing world, severely affected by extreme weather events, epidemic outbreaks, economic shocks and conflicts, it is of fundamental importance to estimate where and how many the most vulnerable people are. In this talk, I will give an overview of current applications of complexity and data science for the Sustainable Development Goals (SDGs), with a deep dive on predictive modeling of food insecurity. In this context, I will focus on the main challenges and differences in doing research in the context of humanitarian organizations with respect to academia, and in bridging the gap between these two worlds.

Survival function: a few things about academia I learnt during the last 10 CCS

An early YRNCS/yrCSS enthusiast shares an incomplete, anecdotal, subjective, but honest series of suggestions that helped him through the bumpy road that is an academic career.

An Introduction to Agent-Based Modelling with NetLogo

This is a quick guide to help you recreate a simple SIR model as an ABM and expand it to include additional social behaviours (many would argue: fundamental human needs). It is designed to give you a flavour of the capabilities of ABM, the ease and intuitiveness of development and the enormous amount of freedom that it provides compared to other approaches.

Wiki game

You all know about the six degrees of separation in human social networks, and probably would think that is applicable to any ‘organically’ growing network. Well, have you ever had this thought about Wikipedia pages? Do you think the largest community-created knowledge network has such a property? Let us test our expectations using a hands-on activity – called as the ‘Wiki game’. In this game, you need to use your laptop/mobile device to go from a given Wikipedia page to another through (Wikipedia) hyperlinks, while also minimizing the number of clicks and time. Are you ready for the challenge?

We will be using a link to get to a privately hosted game by the yrCSS. If you cannot see the game specified, please contact the hosts. We will maintain a leaderboard across games, and the top scorer wins.

Online Pub quiz

A live trivia quiz with questions from Complexity Science where Warm-Up participants join online and get the chance to win prizes. The questions are multiple-choice, short, and fun. No preparation required; join from a web browser or mobile app, answer questions synchronously with everyone, and climb higher on the live scoreboard!

Social event

This year we decided to warm up with the Laser Tag game! Three rounds of exciting game await you! A location in centre of Lyon will let the evening finish in an informal atmosphere.
