Gisele DE CAMPOS RIBEIRO, Insights on perceived obsolescence by consumers
In an article published in The Conversation France, Dr. Gisele de Campos Rebeiro (PSB), together with her co-authors, Dr. Emmanuelle Le Nagard (ESSEC), and Dr. Valérie Guillard (Université Paris Dauphine – PSL) explored different consumer typologies related to perceived obsolescence.
The article, titled “Paradoxe de l’indice de durabilité : les écolos remplacent plus fréquemment leurs produits” (“Paradox of the durability index: eco-conscious consumers replace their products more frequently”), examines how environmentally concerned individuals are often the quickest to replace products—even when those products still work.
The authors identify five dimensions of perceived obsolescence—technological, aesthetic, environmental, social, and commercial—and categorize consumers into three groups. Ironically, the most eco-aware segment is also the most inclined to replace their items early, driven by a desire for improved environmental performance.
The article highlights the urgent need to support second-life solutions such as repair, resale and recycling to reduce the environmental cost of premature product replacement.

Patrice Cailleba, and Nicolas Dufour, Insights on Cybersecurity
In their latest article published in The Conversation France, Dr. Patrice Cailleba, Professor of Management, and Dr. Nicolas Dufour, Affiliate Professor of Finance at Paris School of Business, delve into the discreet but crucial world of ethical hackers; cybersecurity experts who are quietly hired by organizations to test digital defenses and uncover vulnerabilities before malicious hackers can exploit them.

The authors introduce the concept of “silent ethics,” showing how ethical hackers operate within a professional code that requires discretion not only during the mission, but also before and after.
The article, titled “La guerre silencieuse des hackers éthiques” (“The Silent War of Ethical Hackers”), calls on public and private organizations to integrate ethical hacking into their cybersecurity strategies to better mitigate risks in an increasingly digital world.
