Why Employees Accept Lower Pay At Mission-Oriented Companies, Insiya Hussain, Marko Pitesa, Stefan Thau, Michael Schaerer

Research Collection Lee Kong Chian School Of Business

Today’s companies are likely to tout how their work benefits human welfare or “makes the world a better place.” Recent research suggests that this may come with a potential financial drawback for workers, as it can inhibit them from negotiating for higher pay. Over five studies, job candidates consistently reported that they worried asking for higher pay from these companies would be seen as greedy or inappropriate. This suggests they are aware of a common bias, known as motivation purity bias, where managers believe employees interested in material rewards of work (such as pay) are less motivated than those motivated …

Workplace Culture Must Emphasise Mutual Respect [In Chinese], Siow-Heng Ong

Research Collection Lee Kong Chian School Of Business

In a commentary, SMU Professor of Communication Management (Education) Ong Siow Heng discussed the importance of having a respectful culture in the workplace. He opined that one way to appreciate employees is to provide equitable pay and career advancement opportunities for staff, so that workers will know that their employer respects their contribution. Even though more forms of disrespect for workers are being addressed by law, Prof Ong opined that improving respect for the workers’ dignity is best managed by those in workplace leadership even before relevant laws are passed, especially in areas that cannot be covered by law. He …

Seeking Better Sharpe Ratio Via Bayesian Optimization, Peng Liu

Research Collection Lee Kong Chian School Of Business

Developing an excellent quantitative trading strategy to obtain a high Sharpe ratio requires optimizing several parameters at the same time. Example parameters include the window length of a moving average sequence, the choice of trading instruments, and the thresholds used to generate trading signals. Simultaneously optimizing all these parameters to seek a high Sharpe ratio is a daunting and time-consuming task, partly because of the unknown mechanism determining the Sharpe ratio. This article proposes using Bayesian optimization to systematically search for the optimal parameter configuration that leads to a high Sharpe ratio. The author shows that the proposed intelligent search …

Multiracial Identity Integration: Components, Antecedents, And Consequences, Sheila Xi Rui Wee

Dissertations and Theses Collection (Open Access)

Existing research on multiracials has examined how multiracials develop different racial identities. However, empirical research on how multiracial manage and integrate their identities as well as its impact are limited. This dissertation examined key antecedents and consequences associated with the unique process that multiracials undergo to achieve a positive identity via Multiracial Identity Integration (MII). In Study 1, we examined the link between MII, psychological well-being, and cognitive capacity. Results revealed a positive association between MII and psychological well-being as well as some cognitive capacity outcomes. Study 2 replicated the same relationship between MII and psychological well-being/cognitive capacity outcomes. Additionally, …

No Interest In Being Cynical: Conflicting Versus Corresponding Interests Track Variability In The Link Between Personal Control And Cynicism, Bryan Kwok Cheng Choy

Dissertations and Theses Collection (Open Access)

Recent literature indicates that a lack of personal control negatively predicts (social) cynicism, a negative view of others as self-interested and exploitative (Stavrova & Ehlebracht, 2018a, 2019). Despite the ostensibly robust nature of this relationship, I propose that the strength of the link between personal control and cynicism could be more variable than extant findings have suggested. In particular, I argue that variability in the controlcynicism link may be tracked (i.e., moderated) by the extent to which actors in a situation have corresponding or conflicting interests, with the effect of control on cynicism being attenuated when actors are perceived to …

The Fear Of Being Idle: What It Is And How It Relates To Goal Pursuits, Verity Yu Qing Lua

Dissertations and Theses Collection (Open Access)

Modern society places a strong emphasis on making full use of one’s time and the aversion of idleness. While urging people to spend their time wisely can promote productivity and personal striving, an overemphasis on this ideal can also have detrimental effects on their sense of well-being. However, to date, there is limited research on individuals’ belief about aversion towards idle time – in part due to the lack of a measurement scale to assess such a disposition. Thus, the current work proposed a novel construct and measure—the fear of being idle (FOBI)—to capture the individual differences in affective responses …

What Might David Do In The Face Of Goliath? The Effects Of Height On Status-Signaling Behaviours In Males, Nicole Ruiying Chen

Dissertations and Theses Collection (Open Access)

While the extant literature has looked mainly at how attractive, opposite-sex stimuli impacts our behaviour, much less is known regarding how exposure to same-sex stimuli may also wield influence on human behaviors. Proffering an evolutionary-based perspective, this study aims to investigate, in a sample of heterosexual males, how exposure to taller same-sex stimuli will differentially influence conspicuous status-signaling behaviors of shorter males compared to taller males, in the context of a mating motive. Two competing hypotheses are proposed: (1) shorter males will display greater conspicuous status-signaling compared to taller males in the presence of a tall male confederate and (2) …

Effect Of Leader-Member Exchange Social Comparison On Co-Worker’S Envy And Work Behavior Moderated By Perceived Deservingness Of Star Workers, Ronnie Ng

Dissertations and Theses Collection (Open Access)

The extant leader-member exchange (LMX) literature suggests that leaders establish and develop different quality dyadic relationships with members in the same workgroup. High-quality LMX is argued as beneficial to employees. However, studies have overlooked the emotions and behaviors of low-quality LMX employees to determine how they differ from high-quality LMX employees. This study integrates LMX differentiation literature, social comparison theory and attributional theory to examine the role of LMX social comparison (LMXSC) perceptions in triggering help-seeking and knowledge hiding from star co-workers in the workplace. This study also explores the mediating role of dual envy, that is, benign and malicious …

Expressed Humility In Inter-Organization Interactions: Why And When Boundary-Spanning Leaders’ Expressed Humility Can Promote Partner Cooperation Commitment, Wenhao Yang

Dissertations and Theses Collection (Open Access)

In an organization, expressing humility can promote more meaningful and satisfying relationships with others. Given its potentially positive effects, researchers have been interested in studying the promotion and management of expressed humility for decades. Although there is some literature on the mechanism of expressing humility within an organization, none of them has pointed out the positive effects of expressed humility between organizations represented by their boundary-spanning leaders. Specially, no research efforts have been devoted to understanding how expressed humility between partners affects the economic behavior and outcomes of organizations and when it is effective for positive effects.

In this paper, …

The (Simp)Le Truth About Excessive & Obsessive Romantic Behaviors In Men, Daniel Ho

Dissertations and Theses Collection (Open Access)

There has been a growing trend in mainstream media of certain individuals being termed as simps, generally recognized as people who engage in costly or extravagant romantic behaviors toward a romantic interest, but are often met with no reciprocation. It is suggested that simping behaviors appear to be an evolutionarily maladaptive mating strategy where individuals engage in excessive and obsessive behaviors when pursuing a romantic interest. The current research aimed to explore this phenomenon, to identify specific traits and characteristics that are typical of simps and simping behavior. Across a set of two studies comprising an act nomination and act …

A Data-Driven Approach For Scheduling Bus Services Subject To Demand Constraints, Brahmanage Janaka Chathuranga Thilakarathna, Thivya Kandappu, Baihua Zheng

Research Collection School Of Computing and Information Systems

Passenger satisfaction is extremely important for the success of a public transportation system. Many studies have shown that passenger satisfaction strongly depends on the time they have to wait at the bus stop (waiting time) to get on a bus. To be specific, user satisfaction drops faster as the waiting time increases. Therefore, service providers want to provide a bus to the waiting passengers within a threshold to keep them satisfied. It is a two-pronged problem: (a) to satisfy more passengers the transport planner may increase the frequency of the buses, and (b) in turn, the increased frequency may impact …

Steven M. Miller describes six instances in which Singapore has applied AI in the public sector, illustrating different ways of improving its engagement with the public by making government services more accessible, anywhere, anytime, and speeding its responses to public processes and feedback. He illustrates how its leaders made the city a living lab for AI use, and what they learned.

Estimation Of Recursive Route Choice Models With Incomplete Trip Observations, Tien Mai, The Viet Bui, Quoc Phong Nguyen, Tho V. Le

Research Collection School Of Computing and Information Systems

This work concerns the estimation of recursive route choice models in the situation that the trip observations are incomplete, i.e., there are unconnected links (or nodes) in the observations. A direct approach to handle this issue could be intractable because enumerating all paths between unconnected links (or nodes) in a real network is typically not possible. We exploit an expectation–maximization (EM) method that allows dealing with the missing-data issue by alternatively performing two steps of sampling the missing segments in the observations and solving maximum likelihood estimation problems. Moreover, observing that the EM method could be expensive, we propose a …

Insourcing The Smart City: Assembling An Ideo-Technical Ecosystem Of Talent, Skills, And Civic-Mindedness In Singapore, Orlando Woods, Tim Bunnell, Lily Kong

Research Collection College of Integrative Studies

This article examines an alternative model of smart city formation, one based on the principle of insourcing technical competencies and capabilities to those responsible for city governance. This model counters the logic of technological outsourcing upon which many assumptions and critiques of the smart city rest, and thus reveals ways in which a more generative discourse can be forged. Drawing on a series of in-depth interviews with senior stakeholders from public and private sector organizations, we develop a case study of Singapore’s Smart Nation initiative. Through coordinated efforts to reorganize the public sector’s technological functions, develop nation-wide skills upgrading programs, …

Islamic Political Parties And Election Campaigns In Indonesia, Colm A. Fox, Jeremy Menchik

Research Collection School of Social Sciences

Islamist political parties are a structural feature of politics across the Muslim world, raising persisting questions for scholars of democracy. Under what conditions will Islamists moderate to support democracy and pluralism? Under what conditions will they adopt more exclusive behavior? Taking a fresh approach, we focus on electoral competition and the conditions under which Islamic party candidates campaign using either inclusive nationalist appeals or exclusively Islamic appeals. Using a unique data source, we coded the appeals contained on the campaign posters of 572 Islamic party candidates in Indonesia. We found that demographics, urban–rural differences, and the level of government office …

Continuities And Discontinuities In The Cultural Evolution Of Global Consciousness, R. J. Zhang, J. H. Liu, M. Lee, M. H. Lin, T. Xie, S Chen, Angela K. Y. Leung, I-Ching Lee, D. Hodgetts, E. Valdes, S. Choi

Research Collection School of Social Sciences

Global consciousness (GC), encompassing cosmopolitan orientation, global orientations (i.e. openness to multicultural experiences) and identification with all humanity, is a relatively stable individual difference that is strongly associated with pro-environmental attitudes and behaviours, less ingroup favouritism and prejudice, and greater pandemic prevention safety behaviours. Little is known about how it is socialized in everyday life. Using stratified samples from six societies, socializing institution factors correlating positively with GC were education, white collar work (and its higher income) and religiosity. However, GC also decreased with increasing age, contradicting a 'wisdom of elders' transmission of social learning, and not replicating typical findings …

Testing Automated Driving Systems By Breaking Many Laws Efficiently, Xiaodong Zhang, Wei Zhao, Yang Sun, Jun Sun, Yulong Shen, Xuewen Dong, Zijiang Yang

Research Collection School Of Computing and Information Systems

An automated driving system (ADS), as the brain of an autonomous vehicle (AV), should be tested thoroughly ahead of deployment. ADS must satisfy a complex set of rules to ensure road safety, e.g., the existing traffic laws and possibly future laws that are dedicated to AVs. To comprehensively test an ADS, we would like to systematically discover diverse scenarios in which certain traffic law is violated. The challenge is that (1) there are many traffic laws (e.g., 13 testable articles in Chinese traffic laws and 16 testable articles in Singapore traffic laws, with 81 and 43 violation situations respectively); and …

Conceptualizing Condominium Law And Children: Comparing The State Of Strata Titles Law In New South Wales And Singapore, Hang Wu Tang

Research Collection Yong Pung How School Of Law

Purpose: This article conceptualises the legal relations embedded within condominium housing and the various theories of property ownership to ascertain how children’s interest fit within this framework. The laws of two jurisdictions, New South Wales and Singapore are examined to determine how their strata law responds when children’s safety is at stake. Design/methodology/approach: A comparative method using case law, statutes and secondary literature across both jurisdictions is adopted. This article also draws on various theories of property ownership. Findings: Drawing on pluralist moral theories of property law, the thesis advanced is that children’s issues within condominiums should not be subject …

Exploring The Impact Of Collaboration Processes On Policy Networks Success: A Case Study Of Food Policy Councils, Beomgeun Cho, In Hae Noh, April M. Roggio, Luis Felipe Luna-Reyes

Research Collection School of Social Sciences

Innovative forms of collaborative governance have evolved to address a diversity of wicked problems. Collaboration processes involved in these forms of governance appear to have a paradoxical nature, where the necessary inclusiveness and diversity of actors may also be important obstacles for a successful collaboration. We apply theories of collaborative and network governance, and fuzzy-set Qualitative Comparative Analysis, to explore the impact of collaboration process characteristics (network density, diversity, inclusion and participation) on 12 food policy councils. Our findings suggest that collaborative arrangements where diverse stakeholders have equal and inclusive access to active deliberation constitute one path to effective outcomes.

Subjective Socioeconomic Status Moderates Self-Esteem Reactivity To Daily Stressor Exposure: Evidence From A Daily Diary Approach, Yi Jing Chua, Nadyanna M. Majeed, Verity Yu Qing Lua, Chi-Ying Cheng, Andree Hartanto

Research Collection School of Social Sciences

Research on self-esteem reactivity has demonstrated that self-esteem fluctuates in response to daily stressor exposure, and the strength of this relationship varies between individuals. Drawing upon the positive link between objective socioeconomic status (SES) and self-esteem, how subjective SES influences self-esteem reactivity to daily stressor exposure was explored. Using a 7-day daily diary study, the current study (N-participants = 243, N-days = 1651) adopted a multilevel analysis to demonstrate that subjective SES attenuated the within-person association between daily stressor exposure and daily self-esteem, even after controlling for demographics and objective indicators of SES. The interactions were also consistent across social …

Whom Do We Learn From? The Impact Of Global Networks And Political Regime Types On E-Government Development, Beomgeun Cho, Karl R. Rethemeyer

Research Collection School of Social Sciences

This study investigates the impact of global networks on e-government development and the role of political regime types in e-government diffusion through international networks. We built a unique social network dataset that covers 148 countries for the years between 2003 and 2014. Our network dataset is rooted in two assumptions: 1) international organizations serve as peak organizations for international policy networks, 2) public managers who participate in international e-government conferences held by the UN and OECD work as boundary spanners. Our empirical evidence suggests that countries well embedded in global e-government networks receive ideas for public sector innovation from international …

Uniform Nonparametric Inference For Spatially Dependent Panel Data, Jia Li, Zhipeng Liao, Wenyu Zhou

Research Collection School Of Economics

This article proposes a uniform functional inference method for nonparametric regressions in a panel-data setting that features general unknown forms of spatio-temporal dependence. The method requires a long time span, but does not impose any restriction on the size of the cross section or the strength of spatial correlation. The uniform inference is justified via a new growing-dimensional Gaussian coupling theory for spatio-temporally dependent panels. We apply the method in two empirical settings. One concerns the nonparametric relationship between asset price volatility and trading volume as depicted by the mixture of distribution hypothesis. The other pertains to testing the rationality …

Volatility Puzzle: Long Memory Or Anti-Persistency, Shuping Shi, Jun Yu

Research Collection School Of Economics

The log realized volatility (RV) is often modeled as an autoregressive fractionally integrated moving average model ARFIMA(1,d,01,d,0). Two conflicting empirical results have been found in the literature. One stream shows that log RV has a long memory (i.e., the fractional parameter d > 0). The other stream suggests that the autoregressive coefficient α is near unity with antipersistent errors (i.e., d α close to 0 and d close to 0.5) from Model 2Model 2 (ARFIMA(1,d,01,d,0) with α close to unity and d close to –0.5). An intuitive explanation is given. For the 10 financial assets considered, despite that no definitive conclusions …

Young Women In Cities, Yumi Koh, Li Jing, Yifan Wu, Junjian Yi, Hanzhe Zhang

Research Collection School Of Economics

Young women outnumber young men in cities in many countries during periods of economic growth and urbanization. This gender imbalance among young urbanites is more pronounced in larger cities. We use the gradual rollout of special economic zones across China as a quasi-experiment to establish the causes of this gender imbalance. Our analysis suggests that a key contributor is gender-differential incentives to migrate due to rural women’s higher likelihood of marrying and marrying up in cities when urbanization creates more economic opportunities and an abundance of high-income marriage-age men.

The Importance Of The First Generic Substitution: Evidence From Sweden, Aljoscha Janssen, David Granlund

Research Collection School Of Economics

We analyze changes in the willingness to substitute from prescribed pharmaceuticals to more affordable generic equivalents in response to the first experience with a substitution. Using Swedish individual-level data of prescribed and dispensed pharmaceuticals, we em-ploy a dynamic event study and an instrumental variable approach to show that an initial substitution reduces the probability of opposing subsequent substitutions by 39 percent-age points. We recommend that policy-makers target patients with a history of opposed substitution and offer additional discounts to promote substitution as long-term savings outweigh one-time costs.

Impact Of Difficult Negatives On Twitter Crisis Detection, Yuhao Zhang, Siaw Ling Lo, Phyo Yi Win Myint

Research Collection School Of Computing and Information Systems

Twitter has become an alternative information source during a crisis. However, the short, noisy nature of tweets hinders information extraction. While models trained with standard Twitter crisis datasets accomplished decent performance, it remained a challenge to generalize to unseen crisis events. Thus, we proposed adding “difficult” negative examples during training to improve model generalization for Twitter crisis detection. Although adding random noise is a common practice, the impact of difficult negatives, i.e., negative data semantically similar to true examples, was never examined in NLP. Most of existing research focuses on the classification task, without considering the primary information need of …
