Problematic Smartphone Usage, Objective Smartphone Engagement, And Executive Functions: A Latent Variable Analysis, Andree Hartanto, Yi Jing Chua, Frosch Yi Xuan Quek, Joax Wong, Wei Ming Ooi

Research Collection School of Social Sciences

The negative consequences of smartphone usage have seen frequent discourse in popular media. While existing studies seek to resolve these debates in relation to executive functions, findings are still limited and mixed. This is partly due to the lack of conceptual clarity about smartphone usage, the use of self-reported measures, and problems related to task impurity. Addressing these limitations, the current study utilizes a latent variable approach to examine various types of smartphone usage, including objectively measured data-logged screen time and screen-checking, and nine executive function tasks in 260 young adults through a multi-session study. Our structural equation models showed …

Friends Can Help: The Effects Of Relationship In The Chinese Book-Building Process, Ting Luo, Wei Luo, Heng Yue, Lu Zhang

Research Collection School Of Accountancy

Using detailed bidding information in Chinese IPO book-building process, we find that institutional investors who have a close relationship with the underwriter are more likely to participate in bidding and their bidding prices are higher, compared to other institutional investors. We also find that related institutional investors bid higher when the underwriter is more likely to need or receive their support. Further analysis suggests that related institutional investors gain some benefits for their support to the underwriter, including receiving more shares in profitable IPOs, better timing their exit from the IPO in the open market, and receiving more optimistic earnings …

Research Collection Yong Pung How School Of Law

The neoliberal international order is facing a variety of pressing obstacles. One of the most contentious issues is the emergence of new Asian regionalism, which has been driven by the rising economic power of the region and integration based on the Association of Southeast Asian Nations (ASEAN) Plus Six framework. The legalization of the ASEAN way has propelled the New Regional Economic Order (NREO), which reinforces a trade-development nexus alternative to the Washington Consensus and will have far-reaching normative, economic, and geopolitical effects on the world. Given the proliferation of trade and investment initiatives including the ASEAN Economic Community and …

Higher Well-Being Individuals Are More Receptive To Cultivated Meat: An Investigation Of Their Reasoning For Consuming Cultivated Meat, Angela K. Y. Leung, Mark Chong, Tricia Marjorie Fernandez, Shu Tian Ng

Research Collection School of Social Sciences

It is evident that over-consumption of meat can contribute to the emission of hazardous greenhouse gases. One viable way to address such climate impact is to make people become more aware of more sustainable diet options, such as cultivated meat. However, it is challenging to instigate change in people's meat-eating habit, and empirical works have been examining the psychological factors that are related to consumers' willingness to consume cultivated meat. Research has suggested that psychological well-being can play a role in the meaning-making of food consumption, with higher well-being individuals showing more recognition of other sociocultural benefits of consuming food …

Mobility Repertoires: How Chinese Overseas Students Overcame Pandemic-Induced Immobility, Jiaqi M. Liu, Rui Jie Peng

Research Collection School of Social Sciences

The burgeoning field of immobility studies focuses on how migratory aspirations and capabilities shape a given (im)mobility status but devotes scant attention to how people traverse different (im)mobility categories. Through a case study of Chinese students in the United States during the COVID-19 pandemic, this article develops two arguments to shed light on migrants’ experiences and strategies in mobility transitions. First, during the pandemic, while China's restrictive travel policies and unfavorable public discourses made return migration extremely difficult, Chinese overseas students also felt unwelcome in the United States, due to visa restrictions and Sinophobic violence. This dilemma of being unable …

Authoritarian Propaganda Campaigns On Foreign Affairs: Four Birds With One Stone, Andrew Chubb, Frances Yaping Wang

Research Collection School of Social Sciences

Why do authoritarian states sometimes play up dangerous internationalcrises and embarrassing diplomatic incidents in domestic propaganda? Isit to mobilize, threaten, divert or pacify? Recent studies in comparativepolitics have focused on regime legitimacy and stability as key drivers ofauthoritarian propaganda practices, overlooking other possiblemotivations such as mobilization of the regime’s domestic allies orstrategic signaling aimed at foreign audiences. Foreign policy analysts,meanwhile, have emphasized international dimensions of thepropaganda behavior of China — the contemporary world’s mostpowerful and technologically sophisticated authoritarian state — but haveoften mistakenly framed complementary theories as competingalternative explanations. Paying attention to the multiple domestic andinternational audiences for authoritarian propaganda, …

Discrimination And Cognitive Failures In Singapore And The Us: An Investigation Of Between- And Within-Persons Associations Through Multilevel Modelling, Nadyanna Binte Mohamed Majeed, Kasturiratna Tennakoon Appuhamillage Sandeeshwara Kasturiratna, Verity Yu Qing Lua, Mingyao Li, Andree Hartanto

Research Collection School of Social Sciences

Experiencing everyday discrimination can have a significant negative impact on an individual’s wellbeing. While much attention has been paid to the physical and mental health consequences of discrimination, less is known about how discrimination can affect cognitive health, and most existing work has been conducted in laboratory settings where participants recall discrimination retrospectively. Given the artificial environment and susceptibility to recall bias in such procedures, the current study utilised two daily diary studies, consisting of young adults in Singapore (Study 1; N = 484) and midlife adults from the US (Study 2; N = 3577), to examine the association between …

Does Watching Videos With Natural Scenery Restore Attentional Resources? A Critical Examination Through A Pre-Registered Within-Subject Experiment, Andree Hartanto, Nicole Lee Anne Teo, Verity Y. Q. Lua, Keith Tay, Nicole R. Y. Chen, Nadyanna M. Majeed

Research Collection School of Social Sciences

Existing studies have shown that direct exposure to a real nature environment has a restorative effect on attentional resources after a mentally fatiguing task. However, it remains unclear whether virtual nature simulations can serve as a substitute for real nature experienced in the outdoors to restore executive attention. Given the mixed findings in the literature, the present study sought to examine if viewing videos with natural scenery (vs. a control with urban scenery) restores participants’ working memory capacity – measured by an operation span task – in a high-powered pre-registered within-subject experimental study. Overall, our within-subject experiment did not find …

Improved Marginal Likelihood Estimation Via Power Posteriors And Importance Sampling, Yong Li, Nianling Wang, Jun Yu

Research Collection School Of Economics

Power posteriors have become popular in estimating the marginal likelihood of a Bayesian model. A power posterior is referred to as the posterior distribution that is proportional to the likelihood raised to a power b∈[0,1]. Important power-posterior-based algorithms include thermodynamic integration (TI) of Friel and Pettitt (2008) and steppingstone sampling (SS) of Xie et al. (2011). In this paper, it is shown that the Bernstein–von Mises (BvM) theorem holds for power posteriors under regularity conditions. Due to the BvM theorem, power posteriors, when adjusted by the square root of the auxiliary constant, have the same limit distribution as the original …

On The Spectral Density Of Fractional Ornstein-Uhlenbeck Process: Approximation, Estimation, And Model Comparison, Shuping Shi, Jun Yu, Chen Zhang

Research Collection School Of Economics

This paper introduces a novel method for accurately approximating the spectral density of the discretely-sampled fractional Ornstein-Uhlenbeck (fOU) process. We utilize this approximated spec-tral density to develop an estimation method called the approximated Whittle maximum likelihood method (AWML) for fOU. Additionally, we develop a likelihood-ratio (LR) test using the approxi-mated spectral densities to distinguish between the fractional Brownian motion (fBm) and fOU pro-cesses, two popular models in the volatility literature. Simulation studies demonstrate that the AWML method improves the estimation speed and accuracy compared to existing ones and that the LR test is effective in distinguishing between the two processes …

Learning-Based Stock Trending Prediction By Incorporating Technical Indicators And Social Media Sentiment, Zhaoxia Wang, Zhenda Hu, Fang Li, Seng-Beng Ho, Erik Cambria

Research Collection School Of Computing and Information Systems

Stock trending prediction is a challenging task due to its dynamic and nonlinear characteristics. With the development of social platform and artificial intelligence (AI), incorporating timely news and social media information into stock trending models becomes possible. However, most of the existing works focus on classification or regression problems when predicting stock market trending without fully considering the effects of different influence factors in different phases. To address this gap, this research solves stock trending prediction problem utilizing both technical indicators and sentiments of the social media text as influence factors in different situations. A 3-phase hybrid model is proposed …

The Dialectics Of Leadership Identity Construction: Case Studies From Indigenous Women Leaders, Mariana De Santibanes, Sonia M. Ospina, Seulki Lee, Angela Santamaria, Michelle Marie Evans, Dunen Muelas, Nazareth Guerrero

Research Collection School of Social Sciences

Challenging oversimplified models, the leader identity literature calls for new perspectives of leadership identity construction (LIC). Using a collective leadership lens and narrative methods, this collaborative study explores how Indigenous women’s leadership identities develop within a contest for power and voice. Observations, interviews, and micro-ethnographies helped identify how history, community dynamics and cultural contradictions influence LIC. We find the LIC process to unfold as a dialectical spiral, informed by contradictions experienced when enacting social identities in various spheres of influence. This highlights the intersectionality of salient identities when theorizing LIC, and suggests that minoritized leaders can resignify and ultimately, capitalize …

The Effect Of Social Skills On Analyst Performance, Cong Cong Li, An-Ping Lin, Hai Lu

Research Collection School Of Accountancy

Social skills are important but difficult to measure. So far, few empirical studies have examined the effect of social skills on the performance of professionals. Using the number of LinkedIn connections as a proxy for social skills, we investigate the effect of financial analysts' social skills on their performance. We use multiple ways to validate the measure of social skills and show that analysts with better social skills produce more accurate earnings forecasts and that their stock recommendations elicit stronger market reactions. Furthermore, these socially skilled analysts are more likely to be voted as All-Star Analysts. This study provides the …

Continuous Implementation With Payoff Knowledge, Yi-Chun Chen, Takashi Kunimoto, Yifei Sun

Research Collection School Of Economics

The literature on robust mechanism design assumes players' knowledge about a fixed payoff environment and investigates global robustness of optimal mechanisms to large changes in the information structure. Acknowledging global robustness as a demanding requirement, we propose continuous implementation as a notion of local robustness. Keeping the assumption of payoff knowledge, we say that an SCF is continuously implementable if there exists a mechanism which yields the outcome close to the desired one for all types close to the planner's initial model. We show that when a generic correlation condition is imposed on the class of interdependent-value environments, any (interim) …

Arousing Motives Or Eliciting Stories? On The Role Of Pictures In A Picture–Story Exercise, Philipp Schäpers, Stefan Krumm, Filip Lievens, Nikola Stenzel

Research Collection Lee Kong Chian School Of Business

Picture–story exercises (PSE) form a popular measurement approach that has been widely used for the assessment of implicit motives. However, current theorizing offers two diverging perspectives on the role of pictures in PSEs: either to elicit stories or to arouse motives. In the current study, we tested these perspectives in an experimental design. We administered a PSE either with or without pictures. Results from N = 281 participants revealed that the experimental manipulation had a medium to large effect for the affiliation and power motive domains, but no effect for the achievement motive domain. We conclude that the herein chosen …

Liquidity Constraints, Consumption, And Debt Repayment: Evidence From Macroprudential Policy In Turkey, Sumit Agarwal, Muris Hadzic, Changcheng Song, Yildirim Yildiray

Research Collection Lee Kong Chian School Of Business

Using account-level credit card data from a large Turkish bank, we study the impact of a unique credit card policy that increases minimum payment on consumption and debt repayment. We show that the policy reduces credit card spending and debt, boosts existing debt repayment, and reduces credit card delinquency. The credit card debt of affected consumers falls on average by 50% two years into the policy’s implementation. An increase in minimum payment has a stronger effect than does a decrease of a similar magnitude. We build a benchmark life cycle model with soft liquidity constraint to explain the reduction in …

Covid Time: How Quarantine Affects Feelings Of Elapsed Time, Minju Han, Guy Voichek, Gal Zauberman

Research Collection Lee Kong Chian School Of Business

The lockdowns imposed in response to the COVID-19 pandemic abruptly upended people's lives and daily structure. In this survey of 1,506 Americans conducted in June 2020, we test how quarantine affects feelings of elapsed time (the subjective temporal distance from an event). We find that feelings of elapsed time are determined either by how people spent their time in quarantine or by how much time since an event was spent in quarantine, depending on whether people are still in quarantine at the time of evaluation. Specifically, whether people quarantined alone and the extent to which they maintained a temporal structure …

The Impact Of Subordinates’ Proactive Personality On Empowering Leadership, Xin Zhan

Dissertations and Theses Collection (Open Access)

Research has documented numerous benefits of proactive personality for employees’ job outcomes. However, the success of proactive employees largely depends on their leaders’ empowerment. Extant research has focused on the bright side of proactive personality for inducing empowerment, without considering its risks. We thus have an incomplete understanding of the effects of employees’ proactive personality on empowering leadership. I take a balanced perspective on proactive personality and propose that proactive personality has an inverted U-shaped relationship with empowering leadership, such that empowering leadership is highest when proactive personality is at a moderate level. I argue that leader-member exchange (LMX) mediates …
