Usages du numérique pour le développement durable

Predicting how an individual will perceive the visual complexity of a piece of information is still a relatively unexplored domain, although it can be useful in many contexts such as for the design of human-computer interfaces. We propose here a new method, called Information Complexity Ranking (ICR) to rank objects from the simplest to the most complex. It takes into account both their intrinsic complexity (in the algorithmic sense) with the Kolmogorov complexity and their similarity to other objects using the work of Cilibrasi and Vitanyi on the normalized compression distance (NCD). We first validated the properties of our ranking method on a reference experiment composed of 7200 randomly generated images divided into 3 types of pictorial elements (text, digits, and colored dots). In the second step, we tested our complexity calculation on a reference dataset composed of 1400 images divided into 7 categories. We compared our results to the ground-truth values of five state-of-the-art complexity algorithms. The results show that our method achieved the best performance for some categories and outperformed the majority of the state-of-the-art algorithms for other categories. For images with many semantic elements, our method was not as efficient as some of the state-of-the-art algorithms.

Dans les années 1990, la révolution numérique – et singulièrement Internet – était considérée comme porteuse d’un monde sans intermédiaires privilégiant les relations directes entre les créateurs et les internautes consommateurs. Cette désintermédiation s’est-elle matérialisée ou n’est-elle restée qu’un mythe ? Dans ce dernier cas, les intermédiaires traditionnels sont-ils menacés par de nouveaux acteurs ? Dans le domaine de l’édition, la facilité avec laquelle les auteurs peuvent publier directement leurs livres sur Internet représentet- elle une réelle menace pour les éditeurs traditionnels ? L’explosion des blogs, des réseaux sociaux et des plates-formes de diffusion et de distribution des géants du Net – les Gafa : Google, Apple, Facebook, Amazon – remet-elle en cause les sources de prescription traditionnelles ? Est-elle synonyme d’une plus forte diversité culturelle en garantissant la promotion de produits culturels dits « de niche » ?

Digital and ecological transitions lie at the heart of post-Covid territorial recovery plans and energy sobriety measures in France. While they are sometimes mobilized jointly, the narratives surrounding these two transformations are often developed in parallel — if not in outright opposition. How does local public management coordinate these transition projects at the territorial level ? Drawing on exploratory case studies in two medium-sized cities, this article shows that digital transformation does not drive ecological transformation; rather, the digital maturity of a territory is a prerequisite for its ecological transformation.

As soon as we go beyond the borders of our present and begin to explore remote pasts and futures, management and organization scholars are exposed to two dangers. The first is the exaggeration of continuities and anachronism about the past. The second is the projection of present ordinariness into the future. So how can we describe long-term processes of entrepreneurship, accounting, marketing, finance, information systems or innovation? This edited volume gathers a team of leading interdisciplinary team of scholars inspired by process philosophy, phenomenologies, and critical schools. After presenting issues, debates, and perspectives likely to inspire and guide historical description, the book moves to the concrete translation of this endeavor. Several examples of historical work in entrepreneurship, accounting, and organization studies are then used to show situations in which researchers have had to tackle this resonance between ontology and methodology in their historiography. It will be of great interest to scholars and students of management and organization studies. This books follows the 13th OAP workshop hosted by ESADE on June 2023.
