Does Moving From One-Story Building To Multi-Building Affect The Health Status Of The Elderly: Evidence From China’S Par Program, Lu Cao

Dissertations and Theses Collection (Open Access)

This study investigates the causal impact of relocating from single-story to multistory buildings on the health outcomes of elderly residents in China. Using China’s Poverty Alleviation Relocation (PAR) program as an exogenous policy shock, we employ instrumental variable and difference-in-differences approaches to establish causality. Our analysis of data from the China Health and Retirement Longitudinal Study (2011-2018) reveals a nuanced relationship between vertical living and elderly health. While relocation to multi-story buildings is associated with deterioration in self-reported physical health status, it significantly improves mental health conditions and life satisfaction among elderly movers. We identify two key mechanisms driving these …

Intraday Volatility In Financial Markets: Evidence From High-Frequency Data, Haolin Wang

Dissertations and Theses Collection (Open Access)

In this study, we conduct an analysis of intraday spot volatility using high-frequency data from the SPDR S&P 500 ETF (SPY). We begin with the assumption that the intraday volatility of asset prices exhibits time-variation. To capture this dynamic behavior, we construct proxies for the unobserved spot volatility by applying appropriate estimators to the high-frequency price data. Following the estimation procedure, we employ various forecasting models to generate volatility forecasts. Finally, we evaluate and compare the predictive performance of these models using established forecast evaluation metrics, and analyze the results.

Determinants Of Trading Prices In State-Owned Asset And Equity Transactions: An Empirical Analysis From China, Lixiao Chen

Dissertations and Theses Collection (Open Access)

This thesis examines the determinants of pricing outcomes in state-owned asset transactions using a comprehensive dataset of 3,638 transactions from a major transitional economy. Contrary to conventional expectations, we find that fixed assets consistently receive less favorable pricing compared to equity assets, with significantly lower odds of trading above professional valuation and higher odds of trading below valuation. This pattern persists across multiple specifications and remains robust to propensity score matching approaches that address selection concerns. I further demonstrate that state-owned buyers secure significant advantages in transaction pricing, with dramatically lower odds of paying premiums over valuation or listing prices …

Nature Of Smartphone Use: The Underlying Mechanisms Between Nature Exposure And Urge To Use Social Media, Jia Yi Aw

Dissertations and Theses Collection (Open Access)

The urge to use social media is prevalent and costly in modern society. However, little has been researched on how nature exposure can manage urge to use social media to combat its negative consequences. It was hypothesized that nature exposure through Instagram posts in Study 1 and nature park in Study 2 reduces urge to use social media. The underlying mechanisms were tested in a theory-driven serial mediation model, in which positive emotions, attention restoration and self-regulation served as serial mediators. Study 1 employed Instagram experimental manipulation in a laboratory setting by randomly assigning 206 undergraduates to view Instagram accounts …

Essays On Financial Econometrics, Yuexuan Ren

Dissertations and Theses Collection (Open Access)

This dissertation consists of two papers that contribute to the theory of estimation, inference, and prediction using high-frequency financial data. In the first chapter, time-varying betas from return regressions, commonly used to measure systematic financial market risk, are studied using high-frequency data. A novel econometric framework is introduced for the nonparametric estimation of these betas. The optimal finite-sample inference, in a well-defined sense, is enabled by the local Gaussian property of a generic continuous-time benchmark model under the fixed-k framework. Furthermore, a uniform functional inference theory for spot regressions is developed. The proposed methodology is broadly applicable in empirical settings, …

Environmental Influences Of Zero-Sum Thinking And Its Outcome, Edison Sora Tan

Dissertations and Theses Collection (Open Access)

Zero-sum thinking refers to a generalized mentality or a belief that one person’s gain can only come at the expense of another person’s loss. In this research, I argue that people’s zero-sum thinking is, at least in part, influenced by the interacting characteristics of the environment, namely, resource scarcity and population density. This is because resource scarcity highlights people’s resource insecurity, particularly when population density accentuates potential competition for finite resources. Consequently, zero-sum thinking reduces trust and cooperation as people reduce their commitment to potentially risky social investments. Analysis with data from a large-scale field study and ecological data provided …

More Than Meets The Eye: Misaligned Expectations In Social Interactions For Individuals With Chronic Illness, Janice Patricia

Dissertations and Theses Collection (Open Access)

Despite the importance of social relationships for well-being, individuals with chronic illness often face barriers that deter them from initiating meaningful connections, such as perceived stigma, fear of rejection, or strained relationships upon a disclosure of their illness. These challenges reveal two key misalignments: overestimated negative (or underestimated positive) expectations of social interactions held by individuals with chronic illness, as well as perceptions held by potential acquaintances. The present study examined how these misalignments hinder social interactions and relationship initiation. Study 1 involved individuals with chronic illness and revealed that participants overestimated the likelihood of awkwardness, disrespect, and rejection, while …

What Makes An Experience Meaningful: A Process/Outcome Approach, Clement Yong Hao Lau

Dissertations and Theses Collection (Open Access)

Scant research has investigated how meaning judgement of an experience are derived; even fewer has examined how these judgements shift over time. To address these gaps, the present research introduced Process/Outcome Meaning Model (POMM)—which proposes that meaning can be derived from two distinct aspects of an experience: its process (i.e., the thoughts, feelings, and behaviors that unfold during the experience) and its outcome (i.e., the results or consequences that follow). POMM further suggests that changes in perceived outcomes may lead to corresponding shifts in meaning judgements over time. Across three studies, participants wrote about and reflected on their personal (positive …

Monitoring Incentives And Tax Planning: Evidence From State-Owned Enterprises, Eva Eberhartinger, David M. P. Samuel

Research Collection School Of Accountancy

This study provides new evidence on the association of state ownership and tax planning by showing that a state owner’s monitoring incentives affect a firm’s tax planning. Using the setting of a developed market economy, Germany, we distinguish between state owners that directly benefit from state-owned enterprises’ (SOEs’) income tax payments and those that do not. Our results indicate that state ownership is not associated with less tax planning unless the state owner directly benefits from higher tax payments. These results are robust to various specifications and suggest that shareholders’ monitoring incentives are a determinant of a firm’s tax planning …

Essays On Spatial Economics And International Trade, Yunlong Song

Dissertations and Theses Collection (Open Access)

This dissertation consists of two chapters that study the China’s spatial economy in the context of heterogenous skill workers, local capital investment, and foreign direct investment (FDI). The first chapter studies how production factor accumulations in space respond to economic shocks or events, and how those responses modify the aggregate and distributional impacts of shocks. To examine their responses and implications, we develop a dynamic spatial model that incorporates capital accumulation and skill acquisition. Focusing on China’s trade liberalization and infrastructure expansion in the early 2000s, we show that allowing for capital accumulation amplifies welfare gains and intensifies between-skill inequality, …

Felt Obligation, Knowledge Sharing And Innovation Performance: The Role Of Team Performance Goal Orientation, Zenan Wen

Dissertations and Theses Collection (Open Access)

In today’s dynamic work environment, individual innovation is vital for organizational success. While knowledge sharing is a recognized driver of innovation, less is known about the internal motivational forces that compel employees to share knowledge. Drawing on the role identity theory, this research examines how felt obligation—a normative motivation, whereby individuals, based on their perceived role identities, believe they should care about organizational goals and contribute to them—encourages knowledge sharing and subsequently enhances innovation performance. Furthermore, I theorize that this relationship is strengthened in teams with higher performance goal orientation (TPGO), where norms and expectations regarding performance excellence amplify the …

The Dynamics Of Power Transfer In Organizations: Examining Downward Deference And Its Workplace Consequences, Hoang Bao My Nguyen

Dissertations and Theses Collection (Open Access)

This dissertation examines managerial power transfer as a core mechanism through which less-hierarchical management unfolds in organizations. While traditional management research has emphasized formal authority and top-down control, emerging organizational forms increasingly call on managers to share power with subordinates. Despite growing interest in constructs like empowerment, delegation, and participative leadership, the phenomenon of power transfer remains conceptually fragmented and undertheorized.

To address this, the dissertation defines power transfer as the intentional redistribution of authority, control, or resources by powerholders to lower-power individuals. Chapter 1 develops a typology of power transfer behaviors, organized along two key dimensions: extent of control …

Limit Theory For Local Polynomial Estimation Of Functional Coefficient Models With Possibly Integrated Regressors, Ying Wang, Peter C. B. Phillips

Research Collection School Of Economics

Limit theory for functional coefficient cointegrating regression was recently found to be considerably more complex than earlier understood. The issues were explained and correct limit theory derived for the kernel weighted local level estimator in Phillips and Wang (2023b). The present paper provides complete limit theory for the general kernel weighted local th order polynomial estimators of the functional coefficient and the coefficient derivatives. Both stationary and nonstationary regressors are allowed. Implications for bandwidth selection are discussed. An adaptive procedure to select the fit order  is proposed and found to work well. A robust -ratio is constructed following the new …

The Backdrop Of Leadership: How Environmental Awe Influences Charisma Attributions, Jack Mcguire, Nicolas Bastardoz, Leonie J. Hentrup, David De Cremer, Jochen I. Menges

Research Collection Lee Kong Chian School Of Business

Charisma is often attributed to leaders based on how they look, talk, and behave. Yet very little is known about the role of the physical environment in influencing attributions of leader charisma. The role of the physical environment is crucial because leaders inevitably occupy physical spaces that vary across contexts. In this research, we find that the grandeur of the physical environment, specifically in its ability to induce awe, enhances attributions of charisma for leaders who are not already known to be charismatic. First, in a field experiment, we show that a real business leader is attributed with more charisma …

Voting For Winners And Losers In A Hybrid Regime: How Thailand's 2023 Election Shaped Voter Opinion, Jacob Ricks, Allen Hicken

Research Collection School of Social Sciences

Research in Western Democracies suggests voting has substantive impacts on how one feels about democracy and state institutions. Voting for winners leads to positive feelings while voting for losers has the opposite effect. How, though, do voters interpret electoral results in a system prone to authoritarian intervention? Thailand's 2023 election offers a unique opportunity to examine how voting in a hybrid regime can impact voter opinion. Using a pre- and postelection survey, we demonstrate that, like elections in democracies, an election in a hybrid regime can have a significant impact on voter opinions. When pro-democracy voters win an election in …

Strategizing Towards The Future Hospital: A Systems Thinking Approach, Ashish Kumar, Sean Shao Wei Lam, Sze Ling Chan, Yingqi Xu, Yao Ge, Geoffrey Kah Tack Gui, Hiang Khoon Tan

Research Collection School Of Economics

Background: The complex systemic nature of Future Hospital design in the rapidly ageing city-state of Singapore calls for systems thinking. We apply this approach to answer two research questions: (i) What are the variables that drive the present and future dynamics of the Future Hospital system? (ii) How are these driving variables related? Methods: Causal loop diagrams (CLDs) were developed collaboratively by a cross-functional system modelling team through group modelling discussions and reviews, totalling 20 sessions. Network analysis of the resulting CLDs was used to identify dominant variables. Results: Seven interlocking CLDs (national view, cluster view, and study hospital top …

Valuation Of Crypto Assets On Blockchain With Deep Learning Approach, Xi Zhou, Yin Pang, Esther Ying Yang, Jing Rong Goh, Shaun Shuxun Wang

Research Collection School Of Economics

With the rapid expansion of the blockchain ecosystem, crypto asset valuation has become an essential area of study for investors and institutions. Here, we introduce a deep learning framework that was designed to predict the value index of crypto assets by integrating intrinsic value variables and decomposing market prices into value and sentiment components. The Crypto Asset Value-indexing Model (CAVM) was applied to Ethereum’s cryptocurrency ETH to demonstrate its effectiveness. Four econometric tests were conducted to verify the informativeness, predictiveness, and reasonability of the generated value indices, as well as the efficiency of price decomposition. Our findings suggested that the …

The Prospects Of The High Seas Treaty Decisively Reducing The Negative Biodiversity Impacts Of Distant Water Fishing Operations, Shirley V. Scott, Nengye Liu

Research Collection Yong Pung How School Of Law

International fisheries law has so far proven inadequate to prevent over-fishing on the high seas, a key cause of biodiversity loss in areas of the ocean beyond national jurisdiction (ABNJ). Negotiation of the High Seas Treaty (Agreement under the United Nations Convention on the Law of the Sea on the Conservation and Sustainable Use of Marine Biological Diversity of Areas beyond National Jurisdiction or BBNJ Agreement) afforded an opportunity to respond decisively to the worsening problem. The Treaty was concluded in 2023. It is yet to enter into force. Preparations and negotiations for the Treaty spanned some 20 years. By …

AI infrastructure is evolving faster than the regulation and governance needed to ensure it serves public and planetary interests.

The Latin American Principles For Out-Of-Court Workouts, Aurelio Gurrea-Martinez, Adolfo Rouillon

Research Collection Yong Pung How School Of Law

Out-of-court workouts can save significant costs associated with the initiation of a formal insolvency proceeding. Therefore, they can help minimise the loss of value experienced by an insolvent firm, ultimately contributing to the maximisation of the returns to creditors and the reorganisation of viable but financially distressed businesses. Additionally, an out-of-court agreement can provide a level of flexibility and confidentiality that is usually lacking in formal insolvency proceedings. Thus, an out-of-court workout can serve as a valuable mechanism to deal with a situation of financial distress, especially in the context of countries with inefficient insolvency systems and companies with concentrated …

Entangled Exclusions: Borders, Frontiers And Urban Geopolitics From Northeast India, Prerona Das, Gaurav Mittal, Jasnea Sarma

Research Collection College of Integrative Studies

An epicentre of ethnicity-based identity politics and exclusions, India's northeastern region has long been politically imagined as both a ‘frontier’ and ‘borderland’ for state control, territorialization, extractive economies and (re)developments by colonial and subsequent post-colonial regimes. In post-independence India, the region experienced many territorial assertions made on ethnic grounds. With the rise of religio-national and neoliberal politics, new urban ‘developments’ and connectivity projects in the region have deepened exclusions based on class, caste, ethnic and religious borders. These have, in turn, led to further displacement, enclavization, and ghettoization of minority communities who are deemed ‘non-native’ along ethnocentric lines. Taking two …

Infrastructuring Planetary Rural Geographies: A View From China’S Rural Construction Movement, Ningning Chen, Lily Kong, Yurui Li

Research Collection School of Social Sciences

This commentary responds to Wang et al.'s (2023) call for planetary rural geographies by attending to the neglected infrastructural dimensions. In so doing, we show how China's rural construction movement demonstrates Wang et al.'s (2023) three geographies of planetary rurality: as spaces of crisis, conflict, and hope. Simultaneously, we address how planetary rural thinking can foreground infrastructural geographies and their destabilization of urban-centered discourses, leading to a reconsideration of rural–urban relationality. We then identify new insights that critical infrastructural studies offer to planetary rural geographies. This includes an emphasis on the material grounds, hidden politics, and non-linear temporal patterns of …

The Efficacy Of Incorporating Artificial Intelligence (Ai) Chatbots In Brief Gratitude And Self-Affirmation Interventions: Evidence From Two Exploratory Experiments, Jing Wen Hung, Andree Hartanto, Adalia Y.H. Goh, Zoey K.Y. Eun, K. T. A. Sandeeshwara Kasturiratna, Zhi Xuan Lee, Nadyanna M. Majeed

Research Collection School of Social Sciences

Numerous studies have demonstrated that positive psychology interventions, including brief interventions, can significantly improve well-being outcomes. These findings are particularly important given that many of these interventions are brief and self-administered, making them both accessible and scalable for large populations. However, the efficacy of positive psychology interventions is often constrained by small effect sizes. In light of advancements in generative Artificial Intelligence (AI), this study explored whether integrating AI chatbots into positive psychology interventions could enhance their efficacy compared to traditional self-administered approaches. Study 1 examined the efficacy of a gratitude intervention delivered through Snapchat's My AI, while Study 2 …

What Is Wrong With Workism?, Matthew Hammerton

Research Collection School of Social Sciences

Workism is the phenomenon of people making their work the primary source of meaning and identity in their life. Recent critics of workism have argued that there is a growing trend towards it in many societies and that this is a bad thing. This article brings a philosophical perspective to the debate on workism. It develops a precise account of what workism is and evaluates the main objections raised against it by examining their underlying philosophical assumptions. Ultimately, it is argued that workism, as a way of life, is not as objectionable as its critics suggest.

Dispositional Religiosity Predicts Increased Incidence Of Mixed Emotions: Evidence Across Five Studies Spanning Two Countries, Vincent Y. S. Oh, Andree Hartanto, Ringo M. H. Ho, Eddie M. W. Tong

Research Collection School of Social Sciences

Across five studies (total N = 8,414), we examined whether religious individuals experienced more mixed emotions. Studies 1 and 2 examined associations between dispositional religiosity and mixed emotions, while Study 3 provided a pre-registered replication. Study 4 provided a pre-registered exploratory examination of three potential mediators of the relationship between dispositional religiosity and mixed emotions: trait dialecticism, cognitive reappraisal, and fear of God. Finally, Study 5 provided pre-registered prospective analyses testing associations between dispositional religiosity and mixed emotions 1 month later. Across all studies, positive and negative emotions were also examined, and latent variable structural equation modeling was performed, controlling …

Do Birds Of A Nest Flock Together? A Study Of Home Provinces And Migration Paths Among Filipina Domestic Workers In Hong Kong, Tim F. Liao, Yasmin Y. Ortiga

Research Collection School of Social Sciences

There is strong evidence that migration is networked. However, it is unclear whether having the same province of origin can also lead to similar migratory paths. This study investigates the question of whether a shared home province among Filipina migrant domestic workers in Hong Kong is associated with shared or linked migration paths to Hong Kong. Using a unique data source, the 2017 Survey of Migrant Domestic Workers in Hong Kong, we employed sequence analysis to identify which specific provinces exhibit stronger linkages between migratory trajectories among migrants from the same provinces and if so, whether certain provincial characteristics matter. …

Exploring The Relationship Between Intrinsic Capacity And Social Participation In Healthy Ageing: Evidence From Singapore, Li Ling Cheong, William Tov, Robin Wai Munn Choo, Chongsheng, Micah (Chen Chongsheng) Tan, Lay Khoon Lau, Wee Shiong Lim, Yew Yoong Ding, Paulin Tay Straughan

Research Collection School of Social Sciences

Objective: The World Health Organization has identified intrinsic capacity and functional ability as key constructs in enabling healthy ageing. However, functional ability is distinct from actual levels of social and physical participation, which research has shown to be associated with health and wellbeing. This study distinguishes between functional ability and actual levels of social and physical participation, and utilizes the International Classification of Functioning, Disability and Health framework to examine the relationship between IC and the two constructs. Methods: This study utilizes cross-sectional self-reported data from a nationally representative panel of Singapore residents aged 56–75 (N = 6,434). We performed …

Educating Indians, Learning ‘Indianness’: Navigating Pluralistic Educational Infrastructures In Diasporic Singapore, Emma Grimley, Orlando Woods, Lily Kong

Research Collection College of Integrative Studies

This paper advances the idea of ‘educational infrastructures’ to explore the slippages created by national education frameworks and the everyday ways in which citizen-subjects learn to be part of an ethno-cultural community. In doing so, we tease apart the differences between education as a top-down process of citizen-making and learning as a poly-directional assemblage of behaviours and influences that permeate the socio-spatial landscapes of ethnic belonging. We illustrate these theoretical arguments through an analysis of Singapore’s diasporic Indian community and the collapse of linguistically and culturally complex community backgrounds under the Mother Tongue policy. This leads to a pluralisation of …

Public Health Messaging About Dengue On Facebook In Singapore During The Covid-19 Pandemic: Content Analysis, Shirley S. Ho, Mengxue Ou, Nova Mengxia Huang, Agnes S.F. Chuah, Vanessa S. Ho, Sonny Rosenthal

Research Collection College of Integrative Studies

Background:Dengue, a mosquito-borne disease, has been a health challenge in Singapore for decades. In 2020, during the COVID-19 pandemic, Singapore encountered a serious dengue outbreak and deployed various communication strategies to raise public awareness and mitigate dengue transmission.Objective:Drawing on the Crisis and Emergency Risk Communication (CERC) framework, this study examines how dengue-related messages communicated on Facebook (Meta) during the COVID-19 pandemic fall into the CERC themes. This study also seeks to understand how these themes differ between dengue outbreak (eg, 2020) and nonoutbreak years (eg, 2021). In addition, we explore how message themes on dengue changed across different CERC phases …
