The Path To Greening Our Future, Havovi Joshi

Asian Management Insights

More than half of humanity currently lives in urban areas, and the United Nations predicts that figure will reach 70 percent by 2050. Cities worldwide already generate a significant amount of solid waste annually, adding to vexing issues that the global community is trying to address–demand for transportation, air pollution, access to public open spaces, urban sprawl, and general sustainability challenges. Throw in global warming and the copious greenhouse gas (GHG) emissions borne of construction activities, and the challenge of creating the necessary urban infrastructure to cope comes into sharp focus.

Which Idea To Pursue? Gender Differences In Novelty Avoidance During Creative Idea Selection, Mengzi Jin, Roy Y. J. Chua

Research Collection Lee Kong Chian School Of Business

Despite women having made significant progress in the modern workforce, gender gaps are still evident in creative work. In this paper, we propose that, although women and men are equally capable of generating creative ideas, gender differences emerge during the idea-selection stage. Specifically, compared with men, women engage in higher novelty avoidance during idea selection—the degree to which one selects an idea that is less novel than the most novel idea one has generated. In two laboratory studies and a field survey involving creative professionals, we found significant gender differences in novelty avoidance during idea selection and identified women’s concerns …

Validity Of Social Media Assessments In Personnel Selection: A Systematic Review Of The Initial Evidence, Franz W. Mönke, Nicolas Roulin, Filip Lievens, Marie Therese Bartossek, Philipp Schäpers

Research Collection Lee Kong Chian School Of Business

Approximately two out of three recruiters report screening candidates’ KSAOs (knowledge, skills, abilities, and other characteristics like personality) or hireability based on social media platforms (e.g., Facebook, LinkedIn), often referred to as cybervetting. However, various researchers cautioned against engaging in this emerging practice due to questions about the validity of social media assessments. Therefore, we conducted a systematic review to summarize initial research on the psychometric properties of social media assessments: Reliability, construct-related validity, and criterion-related validity. Our literature search yielded 12 studies with 536 raters and 2,019 ratees, and most of these studies addressed personality traits. We found that …

Research Collection Lee Kong Chian School Of Business

PurposeThe recent COVID-19 pandemic caused a severe economic downturn. Employees working in these organisations face employment uncertainty. The pandemic disrupted their daily routines, and it added a layer of complexity to the already resource-constrained environment. During these times, employees would conserve their resources to maintain competitiveness, one of which is knowledge hiding. While economic activities are resuming, the appearance of new variants could mean the transition towards endemicity could be put on hold. Hence, there is a need to rethink the behaviour of employees as they would have elevated levels of anxiety towards resuming daily work activities. Therefore, this study …

Urban H: Housing, Heat, And Health, Loretta Lees

Asian Management Insights

Future policy needs to triangulate the ‘triple-H’ to help marginalised urban populations.

1. The urban heat island effect generates disproportionately high temperatures in urban settlements compared to non-urban ones, leading to increased heat-related illnesses and mental health issues, especially among vulnerable and marginalised populations living in poorly-planned or -resourced areas.

The Urban-H research agenda by Boston University’s Initiative on Cities focuses on the interconnected effects of housing, heat, and health (triple-H) to develop a resilience index for cities.

3. The proposed global Urban-H Index could help cities worldwide address the triple-H crisis by guiding policymakers to craft equitable, as well …

Revisiting The Conflict-Resolving Problem From A Semantic Perspective, Jinhao Dong, Jun Sun, Yun Lin, Yedi Zhang, Murong Ma, Jin Song Dong, Dan Hao

Research Collection School Of Computing and Information Systems

Collaborative software development significantly enhances development productivity by enabling multiple contributors to work concurrently on different branches. Despite these advantages, such collaboration often increases the likelihood of causing conflicts. Resolving these conflicts brings huge challenges, primarily due to the necessity of comprehending the differences between conflicting versions. Researchers have explored various automatic conflict resolution techniques, including unstructured, structured, and learning-based approaches. However, these techniques are mostly heuristic-based or black-box in nature, which means they do not attempt to solve the root cause of the conflicts, i.e., the existence of different program behaviors exhibited by the conflicting versions.In this work, we …

Hi3d: Pursuing High-Resolution Image-To-3d Generation With Video Diffusion Models, Haibo Yang, Yang Chen, Yingwei Pan, Ting Yao, Zhineng Chen, Chong-Wah Ngo, Tao Mei

Research Collection School Of Computing and Information Systems

Despite having tremendous progress in image-to-3D generation, existing methods still struggle to produce multi-view consistent images with high-resolution textures in detail, especially in the paradigm of 2D diffusion that lacks 3D awareness. In this work, we present High-resolution Image-to-3D model (Hi3D), a new video diffusion based paradigm that redefines a single image to multi-view images as 3D-aware sequential image generation (i.e., orbital video generation). This methodology delves into the underlying temporal consistency knowledge in video diffusion model that generalizes well to geometry consistency across multiple views in 3D generation. Technically, Hi3D first empowers the pre-trained video diffusion model with 3D-aware …

Multimodal Misinformation Detection By Learning From Synthetic Data With Multimodal Llms, Fengzhu Zeng, Wenqian Li, Wei Gao, Yan Pang

Research Collection School Of Computing and Information Systems

Detecting multimodal misinformation, especially in the form of image-text pairs, is crucial. Obtaining large-scale, high-quality real-world fact-checking datasets for training detectors is costly, leading researchers to use synthetic datasets generated by AI technologies. However, the generalizability of detectors trained on synthetic data to real-world scenarios remains unclear due to the distribution gap. To address this, we propose learning from synthetic data for detecting real-world multimodal misinformation through two model-agnostic data selection methods that match synthetic and real-world data distributions. Experiments show that our method enhances the performance of a small MLLM (13B) on real-world fact-checking datasets, enabling it to even …

Thoughts To Target: Enhance Planning For Target-Driven Conversation, Zhonghua Zheng, Lizi Liao, Yang Deng, Ee-Peng Lim, Minlie Huang, Liqiang Nie

Research Collection School Of Computing and Information Systems

In conversational AI, large-scale models excel in various tasks but struggle with target-driven conversation planning. Current methods, such as chain-of-thought reasoning and tree-search policy learning techniques, either neglect plan rationality or require extensive human simulation procedures. Addressing this, we propose a novel two-stage framework, named EnPL, to improve the LLMs’ capability in planning conversations towards designated targets, including (1) distilling natural language plans from target-driven conversation corpus and (2) generating new plans with demonstration-guided in-context learning. Specifically, we first propose a filter approach to distill a high-quality plan dataset, ConvPlan1. With the aid of corresponding conversational data and support from …

Experimental Evidence Of Instagram Influencers’ Impact On Well-Being, Kimberly Yiting T'Ng, Kai Qin Chan, Andree Hartanto

Research Collection School of Social Sciences

With Instagram influencers holding significant sway over public perception, their presumed psychological impact on young adults has gathered public attention. It has been claimed that influencers, known for showcasing enviable lifestyles, have the potential to affect their followers’ well-being. However, these claims have been based on correlational data that focuses on diffused indicators of social media consumption rather than specific features of Instagram. This limits our insight into the direct effects of Instagram on well-being. We experimentally investigated the effects of a brief exposure to Instagram influencers on the well-being. Our results showed that viewing profiles of demographically similar social …

Against The Substitutive Approach To Ai In Healthcare, Rand Hirmiz

Research Collection School of Social Sciences

Paul Bloom has famously argued against the need for empathy in clinicians, while Sally Dalton-Brown has argued that AI need not be capable of empathy to be a good carer. In this paper, the capacity for AI to substitute for human clinicians is assessed from a bioethical perspective, primarily through the evaluation of the arguments put forth by Dalton-Brown and Bloom concerning empathy in healthcare. In opposition to both Bloom and Dalton-Brown, this paper argues that (1) empathy is essential to providing good care or deep care (that is, care that goes beyond the mere fulfilment of medical tasks), (2) …
