How Behavioral Science Can Improve The Return On Ai Investments, David De Cremer, Shane Schweitzer, Jack Mcguire, Devesh Narayanan

Research Collection Lee Kong Chian School Of Business

Many AI projects fail because leaders treat adoption as a tech purchase instead of a behavioral change problem. People resist tools that disrupt routines, overreact to visible AI errors, and prefer familiar human judgment. As a result, even good systems fail to gain purchase. Leaders can address this problem by applying “Behavioral Human-Centered AI” across the AI adoption cycle. In the design phrase, companies should co-design with diverse users, add purposeful friction where it improves scrutiny, require beta tests with subgroup results and behavioral input. During adoption, they should frame AI as an augmenter, disclose limits and safeguards, use explainability …

Love, Community, Errantry: Relational Approaches Toward Mathematical Mistakes, Melissa Adams Corral, Romina S. Peña-Pincheira, José Martínez Hinestroza

Teaching and Learning Faculty Publications

In this article we explore ways of approaching what educators and researchers perceive as mistakes that are consistent with views of mathematics that tolerate ambiguity, contradiction, and multiple possible truths. The approaches we describe draw on works within and beyond the field of mathematics education and detail theories from biologist Humberto Maturana, community organizers Bob Moses and Ella Baker, and poet-philosopher Edouard Glissant. These alternative theoretical perspectives are distinctly relational in their approach. They can build on the field’s current conceptualizations of pedagogical responses to errors in ways that attend to calls for broadening what it means to do mathematics …

Delayed Presentation Of A Retained Colonic Segment In A Child With Intestinal Failure On Teduglutide, Rachel C Bordelon, Sarah J Varalla, Varaha S Tammisetti, Mohamed M Shahin, Amanda Tchakarov, Essam Imseis, Allison L Speer

Faculty, Staff and Student Publications

Teduglutide is a glucagon-like peptide 2 (GLP-2) analogue that was approved by the United States Food and Drug Administration for the treatment of pediatric (>1 year) intestinal failure due to short bowel syndrome in 2019. GLP-2 analogues promote rapid intestinal adaptation, increasing the absorptive capacity of residual intestine after surgical resection to aid the achievement of enteral autonomy or reduce parenteral nutrition requirements. Despite relatively few reported side effects, there is a theoretical risk of proliferative complications. Here we present an intriguing case of a pediatric patient found to have a decade-long retained, discontinuous segment of colon from a …

It explores fungal protease families, their roles in intracellular peptide processing, and fungal survival strategies. …

Technology Discontinuance: A Systematic Literature Review And Research Agenda, Birgit Altrichter, Sabine Benoit

Research Collection Lee Kong Chian School Of Business

Technology discontinuance by users who quit digital services such as social media or lose interest in their devices after a few weeks is a common phenomenon. Yet it has received little research attention; the few studies that address it are scattered across disciplines. Research into customer churn is more prevalent, but it implies switching providers rather than halting usage altogether. By moving beyond discipline-based knowledge boundaries and conducting a systematic literature review, the current article proposes a technology discontinuance framework, which details seven technology discontinuance types (overuse, overload, proficiency, disenchantment, social, circumstantial, and solution) and their drivers. For example, guilt …

Managing The Personalization Paradox: Lessons From Spotify’S Ai Dj, Anirban Mukherjee, Hannah H. Chang, Jonathan Wibowo

Research Collection Lee Kong Chian School Of Business

This case study uses Spotify’s AI DJ to examine the “personalization paradox,” where product features designed to deepen user connection can instead cause alienation. An analysis of over 1,400 user comments identifies three core frictions: a perceived loss of user agency, mismanaged expectations for the human-like AI, and a scalability bottleneck that led to repetitive content. Students are placed in the role of a product manager tasked with developing a prioritized roadmap to address these issues, forcing them to grapple with the critical trade-offs between technological capability and user psychology.

Foreign Director Exit In The Midst Of Deteriorating Bilateral Political Relations, Xiaocong Tian, Yuehua Xu, Daphne W. Yiu

Research Collection Lee Kong Chian School Of Business

Amid global geopolitical realism pushing for a race of hegemonic rivalry nowadays, an outflow of global human talents is a pressing organizational concern. Our study draws attention to the underexamined phenomenon of the exit of foreign directors from their host countries during geopolitical tensions. Theorizing from a sensemaking logic, we posit that the deterioration of bilateral political relations serves as an unexpected event that activates foreign directors’ schemas for dual identity conflict, propelling them to react behaviorally to such identity threats by exiting the board in the host country. In addition, we further posit that the sensemaking process is contingent …
