The Effects Of Counterfactual Thinking On Everyday Meaning, Wynn Tan

Dissertations and Theses Collection (Open Access)

Meaning-making literature largely focuses on predictors of global meaning rather than situational meaning. This is insufficient as both levels of meaning are necessary for a sustained sense of meaning. Past studies found evidence that downward counterfactuals can enhance the meaningfulness of events. However, those findings may be due to existing studies’ focus on major events and did not study how meaning could change over time. For everyday events, upward counterfactuals were proposed to be more apt in enhancing meaning. Using a multiphase diary study, this paper examined whether upward counterfactual thinking predicted event meaningfulness, and more specifically if it was …

Sorry, Locals Only: An Experimental Investigation Of The Affective, Behavioural, And Cognitive Consequences Of National Identity Denial, Nadyanna Binte Mohamed Majeed

Dissertations and Theses Collection (Open Access)

Existing literature shows that experiences of identity denial and questioning (IDQ) present two major consequences for racial minority groups: increased negative affect and behaviours to reassert one’s identity. The current thesis addresses two limitations in this literature—concerns about generalisability to non-US contexts, and potential consequences for cognitive functioning—by examining IDQ effects on individuals from distinct racial groups in Singapore. Through a correlational survey, Study 1 provided evidence for the incidence of IDQ in Singapore across the three racial groups, although IDQ reports were generally higher among racial minority groups (i.e., Malay and Indian) than the racial majority group (i.e., Chinese). …

Undiscounted Recursive Path Choice Models: Convergence Properties And Algorithms, Tien Mai, Emma Frejinger

Research Collection School Of Computing and Information Systems

Traffic flow predictions are central to a wealth of problems in transportation. Path choice models can be used for this purpose, and in state-of-the-art models—so-called recursive path choice (RPC) models—the choice of a path is formulated as a sequential arc choice process using undiscounted Markov decision process (MDP) with an absorbing state. The MDP has a utility maximization objective with unknown parameters that are estimated based on data. The estimation and prediction using RPC models require repeatedly solving value functions that are solutions to the Bellman equation. Although there are several examples of successful applications of RPC models in the …

Transboundary Air Pollution And Cross-Border Cooperation: Insights From Marine Vessel Emissions Regulations In Hong Kong And Shenzhen, Seung Kyum Kim, Terry Van Gevelt, Paul Joosse, Mia M. Bennett

Research Collection College of Integrative Studies

Many coastal cities regulate shipping emissions within their jurisdictions. However, the transboundary nature of air pollution makes such efforts largely ineffective unless they are accompanied by reciprocal, legally-binding regulatory agreements with neighbouring cities. Due to various technical, economic, and institutional barriers, it has thus far been difficult to isolate the effects of legally-binding cross-border cooperation on vessel emissions at the city-level. We exploit the unique administrative characteristics of Hong Kong and its relationship with neighbouring cities in China's Pearl River Delta to isolate the effect of legally-binding cross-border cooperation. Using a regression discontinuity design, we find that Hong Kong's unilateral …

Labor Market Institutions And The Incidence Of Payroll Taxation, Jinyoung Kim, Seonghoon Kim, Kanghyock Koh

Research Collection School Of Economics

Despite the unambiguous predictions of the canonical model of a competitive labor market, empirical studies of the labor market effects of payroll taxation provide conflicting evidence. We estimate the labor market impacts of payroll taxation in Singapore, the country with the most competitive and flexible labor market among the countries investigated in the literature. By exploiting the sharp reduction in payroll tax rate when workers turn 60, we find that the reduced payroll tax rate in Singapore has a large effect on wages without changes in employment. Our meta-analysis shows consistent evidence that varying degrees of labor market competitiveness across …

Nonprofits As Socially Responsible Actors: Neoliberalism, Institutional Structures, And Empowerment In The United Nations Global Compact, Alwyn Lim

Research Collection School of Social Sciences

Nonprofit and nongovernmental organizations have become prominent participants in a global organizational responsibility movement. This trend of nonprofit responsibility is puzzling because nonprofits are presumably already dedicated to the pursuit of collective well-being objectives. This article examines the nonprofit responsibility movement from a cultural perspective, whereby broader cultural changes at the level of international organizations have constructed nonprofit entities as empowered and socially responsible actors. Using the case of the United Nations Global Compact, a global framework for corporate social responsibility, the author shows how (1) the construction of cultural meanings of autonomy and decentralization in the neoliberal context, (2) …

Rural Revitalization In China: Towards Inclusive Geographies Of Ruralization, Ningning Chen, Lily Kong

Research Collection School of Social Sciences

This commentary welcomes Gillen et al.'s geographies of ruralization as an alternative to the urban-centered analysis of socio-spatial transformation in post-reform China. We offer three perspectives to further develop such alternative articulation by drawing on China's most recent geographical experiences of rural revitalization. The first is the ‘top-down’ process of rural revitalization launched by different levels of Chinese state agents and how this is divergent from local needs or embedded in bottom-up engagement. The second is the temporal dimension of ruralization highlighting how uses of the past are implicated in and legitimize the state agenda of rural revitalization. The third …

A Global Experiment On Motivating Social Distancing During The Covid-19 Pandemic, Nicole Legate, Thuy-Vy Nguyen, Andree Hartanto

Research Collection School of Social Sciences

Finding communication strategies that effectively motivate social distancing continues to be a global public health priority during the COVID-19 pandemic. This cross-country, preregistered experiment (n = 25,718 from 89 countries) tested hypotheses concerning generalizable positive and negative outcomes of social distancing messages that promoted personal agency and reflective choices (i.e., an autonomy-supportive message) or were restrictive and shaming (i.e., a controlling message) compared with no message at all. Results partially supported experimental hypotheses in that the controlling message increased controlled motivation (a poorly internalized form of motivation relying on shame, guilt, and fear of social consequences) relative to no message. …

Hierarchical Value Decomposition For Effective On-Demand Ride Pooling, Hao Jiang, Pradeep Varakantham

Research Collection School Of Computing and Information Systems

On-demand ride-pooling (e.g., UberPool, GrabShare) services focus on serving multiple different customer requests using each vehicle, i.e., an empty or partially filled vehicle can be assigned requests from different passengers with different origins and destinations. On the other hand, in Taxi on Demand (ToD) services (e.g., UberX), one vehicle is assigned to only one request at a time. On-demand ride pooling is not only beneficial to customers (lower cost), drivers (higher revenue per trip) and aggregation companies (higher revenue), but is also of crucial importance to the environment as it reduces the number of vehicles required on the roads. Since …

Variation And Efficiency Of High-Frequency Betas, Congshan Zhang, Jia Li, Viktor Todorov, George Tauchen

Research Collection School Of Economics

This paper studies the efficient estimation of betas from high-frequency return data on a fixed time interval. Under an assumption of equal diffusive and jump betas, we derive the semiparametric efficiency bound for estimating the common beta and develop an adaptive estimator that attains the efficiency bound. We further propose a Hausman type test for deciding whether the common beta assumption is true from the high-frequency data. In our empirical analysis we provide examples of stocks and time periods for which a common market beta assumption appears true and ones for which this is not the case. We further quantify …

Probabilistic Fixed Ballot Rules And Hybrid Domains, Shurojit Chatterji, Souvik Roy, Soumyarup Sadhukhan, Arunava Sen, Huaxia Zeng

Research Collection School Of Economics

We study a class of preference domains that satisfies the familiar properties of minimal richness, diversity and no-restoration. We show that a specific preference restriction, hybridness, has been embedded in these domains so that the preferences are single-peaked at the “extremes” and unrestricted in the “middle”. We also study the structure of strategy-proof and unanimous Random Social Choice Functions on these domains. We show them to be special cases of probabilistic fixed ballot rules (introduced by Ehlers, Peters, and Storcken (2002)).

Storm The Capitol: Linking Offline Political Speech And Online Twitter Extra-Representational Participation On Qanon And The January 6 Insurrection, Claire Seungeun Lee, Juan Merizalde, John D. Colautti, Jisun An, Haewoon Kwak

Research Collection School Of Computing and Information Systems

The transfer of power stemming from the 2020 presidential election occurred during an unprecedented period in United States history. Uncertainty from the COVID-19 pandemic, ongoing societal tensions, and a fragile economy increased societal polarization, exacerbated by the outgoing president's offline rhetoric. As a result, online groups such as QAnon engaged in extra political participation beyond the traditional platforms. This research explores the link between offline political speech and online extra-representational participation by examining Twitter within the context of the January 6 insurrection. Using a mixed-methods approach of quantitative and qualitative thematic analyses, the study combines offline speech information with Twitter …

Competition And Third-Party Platform-Integration In Ride-Sourcing Markets, Yaqian Zhou, Hai Yang, Jintao Ke, Hai Wang, Xinwei Li

Research Collection School Of Computing and Information Systems

Recently, some third-party integrators attempt to integrate the ride services offered by multiple independent ride-sourcing platforms. Accordingly, passengers can request ride through the integrators and receive ride service from any one of the ride-sourcing platforms. This novel business model, termed as third-party platform-integration in this work, has potentials to alleviate market fragmentation cost resulting from demand splitting among multiple platforms. Although most existing studies focus on operation strategies for one single monopolist platform, much less is known about the competition and platform-integration and their implications on operation strategy and system efficiency. In this work, we propose mathematical models to describe …

Managing The Phaseout Of Coal Power: A Comparison Of Power Decarbonization Pathways In Jilin Province, Weirong Zhang, Zhixu Meng, Jiongjun Yang, Yan Song, Yiou Zhou, Changhong Zhao, Jiahai Yuan

Research Collection School Of Computing and Information Systems

With the periodic goals of reaching carbon emission peak before 2030 and achieving carbon neutrality before 2060 (“dual carbon” goals), China shows its unprecedented determination to coal power phaseout. This research takes Jilin Province to showcase possible pathways of coal power units’ phaseout on provincial level. We set up four different coal power phaseout scenarios, under which their transition cost and effectiveness would be calculated, respectively. In terms of natural resource endowment and electricity demand, Jilin Province would achieve a complete coal power phaseout by 2045 or even by 2040. However, after assessing the effectiveness of power transition under the …

Inflation And Ukraine War Make It Challenging For Our Beloved Value Stores To Survive, Aurobindo Ghosh, Taimur Baig

Research Collection Lee Kong Chian School Of Business

In a joint commentary, SMU Assistant Professor of Finance (Education) and Principal Investigator of DBS-SKBI Singapore Index of Inflation Expectations Project Aurobindo Ghosh and Chief Economist and Managing Director at DBS Bank Dr Taimur Baig discussed how global inflationary pressures and rising commodity prices due to war in Ukraine and sanctions against Russia are culminating into a perfect storm and making it challenging for value stores to survive. They also gave advice on what value stores can do to survive this perfect storm.

A Black-Scholes User's Guide To The Bachelier Model, Jaehyuk Choi, Minsuk Kwak, Chyng Wen Tee, Yumeng Wang

Research Collection Lee Kong Chian School Of Business

To cope with the negative oil futures price caused by the COVID-19 recession, global commodity futures exchanges switched the option model from Black-Scholes to Bachelier in April 2020. This study reviews the literature on Bachelier's pioneering option pricing model and summarizes the practical results on volatility conversion, risk management, stochastic volatility, and barrier options pricing to facilitate the model transition. In particular, using the displaced Black-Scholes model as a model family with the Black-Scholes and Bachelier models as special cases, we not only connect the two models but also present a continuous spectrum of model choices.

Gender, Bottom-Line Mentality, And Workplace Mistreatment: The Roles Of Gender Norm Violation And Team Gender Composition, Kenneth Tai, Kiyoung Lee, Eugene Kim, Tiffany D. Johnson, Wei Wang, Michelle K. Duffy, Seongsu Kim

Research Collection Lee Kong Chian School Of Business

Although gender has been identified as an important antecedent in workplace mistreatment research, empirical research has shown mixed results. Drawing on role congruity theory, we propose an interactive effect of gender and bottom-line mentality on being the target of mistreatment. Across two field studies, our results showed that whereas women experienced more mistreatment when they had higher levels of bottom-line mentality, men experienced more mistreatment when they had lower levels of bottom-line mentality. In another field study, using round-robin survey data, we found that team gender composition influenced the degree to which the adoption of a bottom-line mentality by female …

The Vigilante Identity And Organizations, Fan Xuan Chen, Maja Graso, Karl Aquino, Lily Lin, Joey T. Cheng, Katherine Decelles, Abhijeet K. Vadera

Research Collection Lee Kong Chian School Of Business

We test the theoretical and practical utility of the vigilante identity, a self-perception of being the kind of person who monitors their environment for signs of norm violations, and who punishes the perceived norm violator, without formal authority. We develop and validate a measure of the vigilante identity scale (VIS) and demonstrate the scale’s incremental predictive validity above and beyond seemingly related constructs (Studies 1 – 2e). We show that the VIS predicts hypervigilance towards organizational wrongdoing (Studies 2 and 4), punishment intentions and behavior in and of organizations (Studies 3 and 4) as well as in the wider community …

Coping Strategies Mediate The Relation Between Executive Functions And Life Satisfaction In Middle And Late Adulthood: A Structural Equational Analysis, Hui Si Oh, Hwajin Yang

Research Collection School of Social Sciences

Recent studies have suggested that executive functions (EF) predict life satisfaction for older adults. However, the mechanism is not known. By analyzing a sample (N = 3,287, ages 32- 84 years) from the Midlife Development in the United States 2, we examined the mediational role of coping strategies in the relation between EF and life satisfaction. Both active coping and behavioral disengagement mediated the relation between EF and life satisfaction, and age significantly moderated the mediational pathways. Specifically, the positive effect of EF on active coping was more pronounced in middle-aged and older adults than in young adults. However, the …

Sunshine On My Shoulders Makes Me Happy... Especially If I’M Less Intelligent: How Sunlight And Intelligence Affect Happiness In Modern Society, Satoshi Kanazawa, Norman P. Li, Jose C. Yong

Research Collection School of Social Sciences

The savanna theory of happiness proposes that, due to evolutionary constraints on the human brain, situations and circumstances that would have increased our ancestors’ happiness may still increase our happiness today, and those that would have decreased their happiness then may still decrease ours today. It further proposes that, because general intelligence evolved to solve evolutionarily novel problems, this tendency may be stronger among less intelligent individuals. Because humans are a diurnal species that cannot see in the dark, darkness always represented danger to our ancestors and may still decrease our happiness today. Consistent with this prediction, the analysis of …

Revisiting The One-Minute Paper: Personal Reflections, Student Engagement And Assessing The Assessment, Rebecca Pappert Maniates

Research Collection Library

The one-minute paper (OMP) is a popular one-shot session assessment which often consists of asking two questions: 1 . What is the most important thing you learned today? 2 . What questions do you still have? Although simple, each question has a purpose. The first is broad, focusing on the importance of concepts learned (Chizmar & Ostrosky, 1998), and promotes active learning and reflection (Stead, 2005). The second assesses the progress of the learning process and where support is still needed (Chizmar & Ostrosky, 1998).Although studies show the OMP is effective when assessing student knowledge before and after one-shot sessions …

Trust Building Within And Across Cultures: A Study Of Guinea, Xiushun Sun

Dissertations and Theses Collection (Open Access)

With the development of African economy and the increasing Chinese MNCs operating in Africa, there is a need to have a better understanding of the trust relationships between Chinese expatriates and African HCNs in the organizational environment. We adopt both qualitative and quantitative approaches to understand the trust relationships between Chinese supervisors, Guinea supervisors and Guinea subordinates in a Chinese MNC’s subsidiary in Guinea, compare the difference within culture and across culture, and examine how the interpersonal trust and the trust in the organization affect employees’ job performance. In study 1, semi-structured interviews were conducted with 19 Chinese supervisors, 20 …

Dissertations and Theses Collection (Open Access)

Social entrepreneurs are key players that could potentially create new initiatives and long-term solutions for our world to sustain the predicted forthcoming crises of overconsumption. Our world needs both kinds of entrepreneurship, both social and business, to collaboratively stimulate growth in a more balanced manner; however, the creation of social entrepreneurs at a higher rate of success and diffusion remains a challenge. This research proposed a number of new antecedents of social entrepreneurial intention (SEI) that were suggested by an exploratory study. The research was conducted in the context of Thailand and was designed to investigate the effects of different …

Organizational Factors That Facilitate Collective Social Entrepreneurship: An Exploratory Study, Kesarwani Nimisha

Dissertations and Theses Collection (Open Access)

This research aims to contribute to the literature on collective social entrepreneurship (CSE) by exploring and examining the organizational factors that facilitate and motivate participation in CSE. Data were collected through an interview with the founder of a cooperative, and a survey, wherein respondents presented their expectations of a collective, their motivation to join, and the resources they deem important.

It was found that organizational factors, initialled as RRSI (relevance, resources, likelihood of success and innovativeness) which if met, have a reasonable chance of attracting participation in organizations pursuing CSE. These organizational factors had different appeal to stakeholders, based on …

The Grid Bootstrap For Continuous Time Models, Yiu Lim Lui, Weilin Xiao, Jun Yu

Research Collection School Of Economics

This article proposes the new grid bootstrap to construct confidence intervals (CI) for the persistence parameter in a class of continuous-time models. It is different from the standard grid bootstrap of Hansen in dealing with the initial condition. The asymptotic validity of the CI is discussed under the in-fill scheme. The modified grid bootstrap leads to uniform inferences on the persistence parameter. Its improvement over in-fill asymptotics is achieved by expanding the coefficient-based statistic around its in-fill asymptotic distribution that is non-pivotal and depends on the initial condition. Monte Carlo studies show that the modified grid bootstrap performs better than …
