Conditional Neural Heuristic For Multiobjective Vehicle Routing Problems, Mingfeng Fan, Yaoxin Wu, Zhiguang Cao, Wen Song, Guillaume Sartoretti, Huan Liu, Guohua Wu Mar 2024

Conditional Neural Heuristic For Multiobjective Vehicle Routing Problems, Mingfeng Fan, Yaoxin Wu, Zhiguang Cao, Wen Song, Guillaume Sartoretti, Huan Liu, Guohua Wu

Research Collection School Of Computing and Information Systems

Existing neural heuristics for multiobjective vehicle routing problems (MOVRPs) are primarily conditioned on instance context, which failed to appropriately exploit preference and problem size, thus holding back the performance. To thoroughly unleash the potential, we propose a novel conditional neural heuristic (CNH) that fully leverages the instance context, preference, and size with an encoder–decoder structured policy network. Particularly, in our CNH, we design a dual-attention-based encoder to relate preferences and instance contexts, so as to better capture their joint effect on approximating the exact Pareto front (PF). We also design a size-aware decoder based on the sinusoidal encoding to explicitly …


(Trade) War And Peace: How To Impose International Trade Sanctions, Gustavo De Souza, Naiyuan Hu, Haishi Li, Yuan Mei Mar 2024

(Trade) War And Peace: How To Impose International Trade Sanctions, Gustavo De Souza, Naiyuan Hu, Haishi Li, Yuan Mei

Research Collection School Of Economics

What is the most cost-efficient way to impose trade sanctions against Russia? We build a quantitative model of international trade with input–output connections. Sanctioning countries choose import tariffs to simultaneously maximize their income and minimize Russia's income, with different weights placed on these objectives. We find, first, that for countries with low willingness to pay for sanctions against Russia, the most cost-efficient sanction is an approximately 20% tariff on all Russian products. Second, if countries are willing to pay at least US$0.70 for each US$1 drop in Russian welfare, an embargo on Russia's mining and energy products is the most …


My Manager Endorsed My Coworkers’ Voice: Understanding Observers’ Positive And Negative Reactions To Managerial Endorsement Of Coworker Voice., Emily Poulton, Szu-Han Joanna Lin, Shereen Fatimah, Cony Ho, Lance Ferris, Russell Johnson Mar 2024

My Manager Endorsed My Coworkers’ Voice: Understanding Observers’ Positive And Negative Reactions To Managerial Endorsement Of Coworker Voice., Emily Poulton, Szu-Han Joanna Lin, Shereen Fatimah, Cony Ho, Lance Ferris, Russell Johnson

Research Collection Lee Kong Chian School Of Business

Research on managerial voice endorsement has primarily focused on the processes and conditions through which voicers receive their managers’ endorsement. We shift this focus away from the voicers, focusing instead on the dual reactions that endorsement generates for observing employees. Drawing from an approach-avoidance framework, we propose that managerial endorsement of coworker voice could be perceived as a positive and negative stimulus for observers, prompting them to approach opportunities and avoid threats, respectively. Results from a pre-registered experiment and a multi-wave, multi-source field study revealed that managerial endorsement of coworker voice was positively related to observers’ voice instrumentality, thus prompting …


T-Pickseer: Visual Analysis Of Taxi Pick-Up Point Selection Behavior, Shuxian Gu, Yemo Dai, Zezheng Feng, Yong Wang, Haipeng Zeng Mar 2024

T-Pickseer: Visual Analysis Of Taxi Pick-Up Point Selection Behavior, Shuxian Gu, Yemo Dai, Zezheng Feng, Yong Wang, Haipeng Zeng

Research Collection School Of Computing and Information Systems

Taxi drivers often take much time to navigate the streets to look for passengers, which leads to high vacancy rates and wasted resources. Empty taxi cruising remains a big concern for taxi companies. Analyzing the pick-up point selection behavior can solve this problem effectively, providing suggestions for taxi management and dispatch. Many studies have been devoted to analyzing and recommending hotspot regions of pick-up points, which can make it easier for drivers to pick-up passengers. However, the selection of pick-up points is complex and affected by multiple factors, such as convenience and traffic management. Most existing approaches cannot produce satisfactory …


Age And Ideology: The Emergence Of New Political Cleavages In Thailand’S 2566 (2023) Election, Napon Jatusripitak, Jacob Ricks Mar 2024

Age And Ideology: The Emergence Of New Political Cleavages In Thailand’S 2566 (2023) Election, Napon Jatusripitak, Jacob Ricks

Research Collection School of Social Sciences

The Move Forward Party’s victory in Thailand’s 14 May 2566 (2023 CE) election surprised most observers, defying widespread predictions of a Pheu Thai win. Departing from traditional vote-mobilization strategies, Move Forward’s campaign focused largely on social media and broad calls for political reform while eschewing the vote-canvassing networks and economic policy promises that had delivered victory after victory for Pheu Thai. Does Move Forward’s win indicate changes in Thai voting behaviour? Relying on data from an original survey collected the week before and the week after the election, as well as observations from fieldwork, we identify two political cleavages that …


Does Relationship Conflict Reduce Novel Idea Communication Through Perceived Leader Openness? Power Distance Orientation As A Moderator, Ming-Hong Tsai Mar 2024

Does Relationship Conflict Reduce Novel Idea Communication Through Perceived Leader Openness? Power Distance Orientation As A Moderator, Ming-Hong Tsai

Research Collection School of Social Sciences

Purpose: This paper aims to investigate why followers have low perceptions of leader openness and thus feel reluctant to communicate novel ideas by examining leader–follower relationship conflict (i.e. interpersonal incompatibility) and a follower’s power distance orientation (i.e. an acceptance of uneven power distribution in organizations) as antecedents. Design/methodology/approach: The research administrators conducted a three-wave work behavior survey in Study 1, a laboratory experiment in Study 2, and an online experiment in Study 3. Findings: The results demonstrated that leader–follower relationship conflict reduced followers’ perceptions of leader openness. However, the negative impact of relationship conflict became non-significant when followers have high …


Digitally Connected, Evolutionarily Wired: An Evolutionary Mismatch Perspective On Digital Work., Mark Van Vugt, Stephen M. Colarelli, Norman P. Li Mar 2024

Digitally Connected, Evolutionarily Wired: An Evolutionary Mismatch Perspective On Digital Work., Mark Van Vugt, Stephen M. Colarelli, Norman P. Li

Research Collection School of Social Sciences

This paper makes the case for an evolutionary mismatch between digital work and the way human ancestors engaged in work. Psychological adaptations for producing things that early humans needed to survive and thrive, such as cognitive mechanisms for obtaining and processing food, toolmaking, and learning valuable working skills, evolved in the context of small networks of hunter–gatherers. These adaptations are central to understanding the significance of work in human evolution. Evolutionary mismatches operate when novel environments cue ancestral adaptations in ways that no longer provide adaptive benefits. We argue that digital work, although efficient and productive, is misaligned with some …


Exploring The Dynamics Of Cross-Boundary Interactions In Qinglinkou, China: The Perspective Of Networks Of Second-Home Owners, Meiling Wu, Mengqiu Cao, Jiuxia Sun Mar 2024

Exploring The Dynamics Of Cross-Boundary Interactions In Qinglinkou, China: The Perspective Of Networks Of Second-Home Owners, Meiling Wu, Mengqiu Cao, Jiuxia Sun

Research Collection School of Social Sciences

Cross-boundary interactions between second-home owners and local are complex over time–networks form and evolve within second-home owners and between owners and locals, each with its deliberately selective inclusion and exclusion. However, little attention has been paid to this phenomenon in the literature. This study, based on social network analysis alongside qualitative interviews, explores the dynamics of interactions between second-home owners and locals by analysing the networks formed by second-home owners in Qinglinkou, China. The ways in which second-home owners maintain and strengthen pre-existing networks with other owners and forge new links with locals, shape the cross-boundary interactions between the two …


The Link Between People's Social Perceptions Of Cultivated Meat Eaters And Their Acceptance Of Cultivated Meat, Xiaoyu Dai, Angela K. Y. Leung, Mark Chong Mar 2024

The Link Between People's Social Perceptions Of Cultivated Meat Eaters And Their Acceptance Of Cultivated Meat, Xiaoyu Dai, Angela K. Y. Leung, Mark Chong

Research Collection School of Social Sciences

Low consumer acceptance emerges as one important barrier to the introduction of cultivated meat, a novel food which offers an opportunity for more sustainable and ethical meat production. Due to the motives for impression management and self-esteem, one factor that could contribute to people's acceptance of cultivated meat is their perceptions of other individuals who consume cultivated meat. In the current research, two online survey studies with 393 Singaporean undergraduate students and 401 American adults were conducted to explore the perceptions of cultivated meat eaters. In both studies, participants were randomly assigned to read one of three profiles that described …


Envy Influences Interpersonal Dynamics And Team Performance: Roles Of Gender Congruence And Collective Team Identification, Kenneth Tai, Sejin Keem, Ki Young Lee, Eugene Kim Feb 2024

Envy Influences Interpersonal Dynamics And Team Performance: Roles Of Gender Congruence And Collective Team Identification, Kenneth Tai, Sejin Keem, Ki Young Lee, Eugene Kim

Research Collection Lee Kong Chian School Of Business

Our research extends past envy research by considering how envy and gender congruence shape interpersonal dynamics at the dyadic level and their bottom-up effects for team performance. Integrating social comparison theory and social identity theory, we examine when and how dyadic level envy influences team performance. Using time-lagged data from 428 dyads of 161 employees in 51 teams, our results show that envious employees are likely to engage in interpersonal deviance directed toward envied team members and that envied employees are likely to seek advice from envious team members. Gender congruence further influences these relationships, with different patterns for males …


Data Sovereignty And Trade Agreements: Three Digital Kingdoms, Henry S. Gao Feb 2024

Data Sovereignty And Trade Agreements: Three Digital Kingdoms, Henry S. Gao

Research Collection Yong Pung How School Of Law

For centuries, international lawyers have wrestled with the relationship between national sovereignty and international law. This is also the case of international trade law, where the tension between trade liberalization and national sovereignty culminated in the famous “Great 1994 Sovereignty Debate” between the late Prof. John Jackson and other leading scholars when the WTO came into being. As we enter the digital age, the issue of sovereignty resurfaced once again in the form of data sovereignty. In this paper, I will examine provisions in trade agreements which deal with data sovereignty issues, such as restrictions on data flow such as …


Cognitive Control Adjustments Are Dependent On The Level Of Conflict: A Replication Of Zhang Et Al. (2021)., M. Bognar, Z. Szekely, M. A. Varga, K. Nagy, G. Spinelli, Andree Hartanto, N. M. Majeed, N. R. Y. Chen, M. Gyurkovics, B. Aczel Feb 2024

Cognitive Control Adjustments Are Dependent On The Level Of Conflict: A Replication Of Zhang Et Al. (2021)., M. Bognar, Z. Szekely, M. A. Varga, K. Nagy, G. Spinelli, Andree Hartanto, N. M. Majeed, N. R. Y. Chen, M. Gyurkovics, B. Aczel

Research Collection School of Social Sciences

The congruency sequence effect (CSE) is one of the most investigated effects in the cognitive control literature. The conflict monitoring theory suggests that the CSE is the result of adjustments in cognitive control based on perceived conflict. A recent paper by Zhang and colleagues, has investigated whether the manipulation of conflict level by changing distractor incompatibility in a flanker task affects the amount of adjustments in cognitive control. Their study produced mixed findings, somewhat supporting the original conflict monitoring theory, but also suggesting other explanations, such as the repetition expectancy account. We replicated the experimental design in a multisite online …


Island Platforms And The Hyper-Terrestrialisation Of Singapore's Smart City-State, Orlando Woods, Tim Bunnell, Lily Kong Feb 2024

Island Platforms And The Hyper-Terrestrialisation Of Singapore's Smart City-State, Orlando Woods, Tim Bunnell, Lily Kong

Research Collection College of Integrative Studies

This paper foregrounds the importance of underlying territorial formations in realising a vision of the smart city. It argues that as a political technology of the state, territory should be understood as a platform upon which data works and the smart city unfolds. In this view, island territories – of which bordered city-states like Singapore provide paradigmatic examples – provide an integral, yet hitherto unexplored, component in the realisation of urban “smartness”. We illustrate these theoretical arguments through an analysis of how the territorial constraints that characterise Singapore’s island platform enable the state to accurately and effectively realise its vision …

An Integrative Review Of Management Research On Caste: Broadening Our Horizons, Hari Bapuji, Snehanjali Chrispal, Pardeep Singh Attri, Gokhan Ertug, Vivek Soundararajan

Research Collection Lee Kong Chian School Of Business

Even though management research on caste is growing, it is not yet on a clear trajectory to realize its vast potential due to varying terminology and framing of caste, the limited incorporation of directly relevant work from proximate disciplines, and the narrow and selective usage of the attributes of caste. To remove these obstacles, we review 259 scholarly works on caste (216 articles and 43 books and research reports) and develop an integrative framework to i) clarify the contemporary manifestations of caste as being a graded hierarchy, an inherited membership, and a set of socially enforced practices, and ii) summarize …


Profiles Of Activity Engagement And Depression Trajectories As Covid-19 Restrictions Were Relaxed, Jonathan L. Chia, Andree Hartanto, William Tov Feb 2024

Profiles Of Activity Engagement And Depression Trajectories As Covid-19 Restrictions Were Relaxed, Jonathan L. Chia, Andree Hartanto, William Tov

Research Collection School of Social Sciences

Given elevated depression rates since the onset of the pandemic and potential downstream implications, this research examined the association between activity engagement and depression among middle-aged and older adults postlockdown. This study aimed to (a) identify activity engagement profiles among middle-aged and older adults, (b) understand factors associated with profile memberships, and (c) compare depression trajectories across profiles as COVID-19 restrictions eased over 16 months in Singapore. This longitudinal study involved 6,568 middle-aged and older adults. Latent growth analysis was first conducted to obtain estimates of depression trajectories for each individual. Latent profile analysis was then conducted to identify different …


Compellingness In Nash Implementation, Shurojit Chatterji, Takashi Kunimoto, Paulo Daniel Salles Ramos Feb 2024

Compellingness In Nash Implementation, Shurojit Chatterji, Takashi Kunimoto, Paulo Daniel Salles Ramos

Research Collection School Of Economics

A social choice function (SCF) is said to be Nash implementable if there exists a mechanism in which every Nash equilibrium outcome coincides with that specified by the SCF. The main objective of this paper is to assess the impact of considering mixed strategy equilibria in Nash implementation. To do this, we focus on environments with two agents and restrict attention to finite mechanisms. We call a mixed strategy equilibrium “compelling” if its outcome Pareto dominates any pure strategy equilibrium outcome. We show that if the finite environment and the SCF to be implemented jointly satisfy what we call Condition …

Forests Are Chill: The Interplay Between Thermal Comfort And Mental Wellbeing, Loïc Gillerot, Kevin Rozario, Pieter De Frenne, Rachel Oh, Quentin Ponette, Aletta Bonn, Winston Chow, Et Al.

Research Collection College of Integrative Studies

As global warming and urbanisation intensify unabated, a growing share of the human population is exposed to dangerous heat levels. Trees and forests can effectively mitigate such heat alongside numerous health co-benefits like improved mental wellbeing. Yet, which forest types are objectively and subjectively coolest to humans, and how thermal and mental wellbeing interact, remain understudied. We surveyed 223 participants in peri-urban forests with varying biodiversity levels in Austria, Belgium and Germany. Using microclimate sensors, questionnaires and saliva cortisol measures, we monitored intra-individual changes in thermal and mental states from non-forest baseline to forest conditions. Forests reduced daytime modified Physiologically …


Wild Hogs In The Water: Contested Infrastructural Ecologies Of Reservoir Storage In Texas, Sayd Randle Feb 2024

Wild Hogs In The Water: Contested Infrastructural Ecologies Of Reservoir Storage In Texas, Sayd Randle

Research Collection College of Integrative Studies

Reservoirs are developed to store water in reserve for future use. But once built, reservoir sites inevitably hold more than just water, often serving as a key habitat for a range of species. This paper examines how one such animal has transformed water storage facilities and nearby landscapes into contested ground in urbanising areas of Texas, USA. Living around the reservoirs, feral hogs complicate the process of urbanisation by degrading the stockpiled water and infrastructure at the storage sites themselves and by damaging private property throughout the surrounding landscape. Tracking local efforts to manage the hogs, the case study illustrates …

Research Collection School Of Computing and Information Systems

Introduction Many regions in the world are using the population health approach and require a means to measure the health of their population of interest. Population health frameworks provide a theoretical grounding for conceptualization of population health and therefore a logical basis for selection of indicators. The aim of this scoping review was to provide an overview and summary of the characteristics of existing population health frameworks that have been used to conceptualize the measurement of population health. Methods We used the Population, Concept and Context (PCC) framework to define eligibility criteria of frameworks. We were interested in frameworks applicable …


The Affective Embeddings Of Gacha Games: Aesthetic Assemblages And The Mediated Expression Of The Self, Orlando Woods Feb 2024

The Affective Embeddings Of Gacha Games: Aesthetic Assemblages And The Mediated Expression Of The Self, Orlando Woods

Research Collection School of Social Sciences

This paper argues that the motivations for investing money in gacha games can be a function of the affective embedding of players within the game, and the game within broader circuits of cultural affinity and appeal. Whilst research on gacha games – and the specific role of loot boxes therein – has emphasised their associations with gambling, I contend that affect is another trigger that can motivate seemingly irrational playing behaviours. The affective embeddings of gacha games motivate players to curate aesthetic assemblages of virtual content that enable the mediated expression of the self. Drawing on qualitative data generated amongst …


Educational Assortative Mating And Motherhood Penalty In China, Cheng Cheng, Yang Zhou Feb 2024

Educational Assortative Mating And Motherhood Penalty In China, Cheng Cheng, Yang Zhou

Research Collection School of Social Sciences

Mothers earn less than comparable childless women, and such motherhood penalty differs in magnitude by women’s socioeconomic and demographic characteristics. Prior research, however, has rarely considered how the effect of parenthood on women’s income may also depend on the characteristics of their partners. Using data from the China Family Panel Studies 2010–2018, we examine how the effects of motherhood on women’s earnings and within-couple income inequality vary by couples’ educational pairings in China. A large educational gap between spouses–hypergamy or hypogamy–exacerbates the motherhood penalty on a woman’s individual income and her share of the couple’s combined income. However, when the …


Smallholders In Capitalist Agriculture: Persistence And Challenges, Qian Forrest Zhang Feb 2024

Smallholders In Capitalist Agriculture: Persistence And Challenges, Qian Forrest Zhang

Research Collection School of Social Sciences

This paper posits that the majority of “smallholders” in contemporary China are commodity producers who must engage in various commodity exchanges to carry out agricultural production and accomplish their social reproduction. Consequently, “smallholder” refers to a family-based economic operation model, rather than a social identity or psychological identification. Within this framework, the study focuses on the intricate relationships between smallholders, various commodity markets, and other market participants. Specifically, it examines two aspects: the relationship between smallholders and capitalized large-scale producers and other agriculture-related capital entities, and the relationship between smallholders and the commodified labor force. The paper argues that the …

A Dual-Angle Exploration Towards Understanding Lapses In Covid-19 Social Responsibility, Sean T. H. Lee, Jerome J. X. Mah, Angela K. Y. Leung

Research Collection School of Social Sciences

Breaking infection chains requires not just behaviours that allow individuals to stay healthy and uninfected (i.e. health protective behaviours) but also for those who are possibly infected to protect others from their harboured infection risk (i.e. socially responsible behaviours). However, socially responsible behaviours entail costs without clear, immediate benefits to the individual, such that public health-risking lapses occur from time to time. In this important yet understudied area, the current exploratory study sought to identify possible psychological factors that may affect people's likelihood of engaging in socially responsible behaviours. Assuming that self-perceived infection should provide an impetus to engage in …


Confucian Family Ideal And Same-Sex Marriage: A Feminist Confucian Perspective, Sor-Hoon Tan Feb 2024

Confucian Family Ideal And Same-Sex Marriage: A Feminist Confucian Perspective, Sor-Hoon Tan

Research Collection School of Social Sciences

This article engages the views of PRC Confucian scholars who responded to the United States Supreme Court Justice Anthony Kennedy's citing of Confucius in his majority opinion on same-sex marriage in 2015. It questions their separation of tolerance for homosexuality from legalization of same-sex marriage and argue that tolerance is not enough. The arguments in the mainland Confucian discourse about same-sex marriage highlights the historical and persistent entanglement of Confucianism with patriarchy. Instead of reviving traditional patriarchal society, further entrenching and increasing gender inequality, contemporary Confucianism could shape its own unique modern society that aspires to (and hopefully one day …


Navigating Geopolitical Crises For Energy Security: Evaluating Optimal Subsidy Policies Via A Markov Switching Dsge Model, Ying Tung Chan, Maria Teresa Punzi, Hong Zhao Jan 2024

Navigating Geopolitical Crises For Energy Security: Evaluating Optimal Subsidy Policies Via A Markov Switching Dsge Model, Ying Tung Chan, Maria Teresa Punzi, Hong Zhao

Sim Kee Boon Institute for Financial Economics

This paper aims to provide insights on the design of optimal subsidy policies to enhance energy security amidst energy disruptions triggered by geopolitical conflicts. We introduce a novel Markov switching dynamic stochastic general equilibrium (MS-DSGE) model to address the limitations of existing integrated assessment models in environmental evaluation. These models often fail to adequately consider the environmental and economic impacts of geopolitical conflicts and do not prioritize energy security sufficiently in policymaking. Our application of the MS-DSGE model to the Russia–Ukraine conflict reveals significant decreases in output, social welfare, and energy consumption during disruptions. The mere anticipation of an energy …


Local Institutional Investors And Corporate Monitoring: Evidence From Cross-Listed Korean Stocks In The Us Market, Changhwan Choi, Chune Young Chung, Jun Myung Song Jan 2024

Local Institutional Investors And Corporate Monitoring: Evidence From Cross-Listed Korean Stocks In The Us Market, Changhwan Choi, Chune Young Chung, Jun Myung Song

Sim Kee Boon Institute for Financial Economics

Using Korean firms that are cross-listed in the US market, this paper investigates whether there are standalone effects of geographic and market proximity of institutional investors on monitoring performance. We find that Korean institutional ownership is negatively associated with earnings management while the US institutional ownership has no impact on earnings management. This suggests that there is the geographic proximity advantage over the market proximity advantage in the emerging markets. Furthermore, we also show that the impact of geographic proximity is stronger for firms with high informational opacity
