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 …
Smallholders In Capitalist Agriculture: Persistence And Challenges, Qian Forrest Zhang
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 …
Social Engagement, Social Networks, And Well-Being Of Older Adults By Gender And Marital Status, Rachel Wen Yi Ngu, Yi Wen Tan, Yan Er Tan, Wei Tin Hiah
Social Engagement, Social Networks, And Well-Being Of Older Adults By Gender And Marital Status, Rachel Wen Yi Ngu, Yi Wen Tan, Yan Er Tan, Wei Tin Hiah
ROSA Research Briefs
In this research brief, we explore the differences in well-being, social engagement, and social networks amongst groups of married and unmarried male and female older adults and discuss potential policy implications. Our study found that single older adult men fared significantly worse than their married counterparts and single older adult women across different aspects of social well-being, such as social engagement and social support. While this emphasizes the need for increased community efforts to engage men, especially single men, in social activities, specific outreach efforts may be required to better understand their needs and how community programmes can address them.
The Affective Embeddings Of Gacha Games: Aesthetic Assemblages And The Mediated Expression Of The Self, Orlando Woods
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
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 …
Data Sovereignty And Trade Agreements: Three Digital Kingdoms, Henry S. Gao
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 …
An Integrative Review Of Management Research On Caste: Broadening Our Horizons, Hari Bapuji, Snehanjali Chrispal, Pardeep Singh Attri, Gokhan Ertug, Vivek Soundararajan
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 …
Navigating Geopolitical Crises For Energy Security: Evaluating Optimal Subsidy Policies Via A Markov Switching Dsge Model, Ying Tung Chan, Maria Teresa Punzi, Hong Zhao
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
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
The Compatibility Of The Substance Over Form Doctrine With Tax And Investment Treaties: A Case Study Of Lone Star V The Republic Of Korea, Blazej Kuzniacki
The Compatibility Of The Substance Over Form Doctrine With Tax And Investment Treaties: A Case Study Of Lone Star V The Republic Of Korea, Blazej Kuzniacki
Research Collection School Of Accountancy
In late August 2022, the Lone Star tribunal concluded one of the latest awards in tax-related investment treaty disputes (the tax-related claims account for almost USD 1.5 billion of the total of almost USD 4.7 billion claimed in compensation). It also is the first award in which the tribunal dealt with the application of the substance over form doctrine (SOFD) by tax authorities and courts of the host state to prevent the abuse of a double tax treaty (DTT), and the impact of the refusal to accord the claimants the benefits under the DTT via a domestic (Korean) SOFD on …
Lifetime Adversity Predicts Depression, Anxiety, And Cognitive Impairment In A Nationally Representative Sample Of Older Adults In The United States, Sangnam Ahn, Seonghoon Kim, Hongmei Zhang, Aram Dobalian, George Slavich
Lifetime Adversity Predicts Depression, Anxiety, And Cognitive Impairment In A Nationally Representative Sample Of Older Adults In The United States, Sangnam Ahn, Seonghoon Kim, Hongmei Zhang, Aram Dobalian, George Slavich
Research Collection School Of Economics
Objective: Although life stress and adversity have emerged as risk factors for mental health problems and cognitive impairment among older adults, prior studies on this topic have been cross-sectional and based on relatively homogeneous samples. To address these issues, we examined prospective associations between lifetime adversity and symptoms of depression, anxiety, and cognitive impairment in a nationally representative, longitudinal sample of older adults in the U.S. Method: We analyzed data from the Health and Retirement Study (1992-2016). The sample included 3,496 individuals (59.9% female), aged ≥64 years old (M age=76.0 ±7.6 years). We used the individual-level panel data and ordinary …
Childlessness And Sibling Positioning In Upward Intergenerational Support: Insights From Singapore, Dahye Kim, Christine Ho, Bussarawan Teerawichitchainan
Childlessness And Sibling Positioning In Upward Intergenerational Support: Insights From Singapore, Dahye Kim, Christine Ho, Bussarawan Teerawichitchainan
Research Collection School Of Economics
Objective: This brief report aims to explore the role of child-lessness and its interaction with sibling positioning (i.e., birth order and gender) in upward intergenerational support within the context of Asian familial and patrilineal values. Background: Despite the increasing rates of childlessness in Asia, little is known about how childless individuals deviate from or adhere to the patrilineal gendered practices of supporting their older parents. Singapore, a rapidly aging nation that emphasises Confucian familism values and patrilineal practices in guiding its welfare policies, provides an ideal setting for this research investigation. Method: We analysed a sample of 475 Singaporeans aged …
Family Size And Child Migration: Do Daughters Face Greater Trade-Offs Than Sons?, Christine Ho, Yutao Wang, Sharon Xuejing Zuo
Family Size And Child Migration: Do Daughters Face Greater Trade-Offs Than Sons?, Christine Ho, Yutao Wang, Sharon Xuejing Zuo
Research Collection School Of Economics
Daughters may be less likely to migrate with parents because they tend to have more siblings in societies with strong son preference. Exploiting exogenous variation in twinning as an instrument, the authors find that a one unit increase in family size decreases the probability that a daughter migrates by 12.5 percentage points but has negligible effects on sons in China. The negative associations for daughters are stronger when migration restrictions are more stringent. The results indicate gendered family size trade-offs in a novel aspect of parental investment and highlight the need to relax migrant children’s education constraints.
Optimal Nonparametric Range-Based Volatility Estimation, Tim Bollerslev, Jia Li, Qiyuan Li
Optimal Nonparametric Range-Based Volatility Estimation, Tim Bollerslev, Jia Li, Qiyuan Li
Research Collection School Of Economics
We present a general framework for optimal nonparametric spot volatility estimation based on intraday range data, comprised of the first, highest, lowest, and last price over a given time-interval. We rely on a decision-theoretic approach together with a coupling-type argument to directly tailor the form of the nonparametric estimator to the specific volatility measure of interest and relevant loss function. The resulting new optimal estimators offer substantial efficiency gains compared to existing commonly used range-based procedures.
Robust Testing For Explosive Behavior With Strongly Dependent Errors, Yui Lim Lui, Peter C. B. Phillips, Jun Yu
Robust Testing For Explosive Behavior With Strongly Dependent Errors, Yui Lim Lui, Peter C. B. Phillips, Jun Yu
Research Collection School Of Economics
A heteroskedasticity-autocorrelation robust (HAR) test statistic is proposed to test for the presence of explosive roots in financial or real asset prices when the equation errors are strongly dependent. Limit theory for the test statistic is developed and extended to heteroskedastic models. The new test has stable size properties unlike conventional test statistics that typically lead to size distortion and inconsistency in the presence of strongly dependent equation errors. The new procedure can be used to consistently time-stamp the origination and termination of an explosive episode under similar conditions of long memory errors. Simulations are conducted to assess the finite …
High-Dimensional Iv Cointegration Estimation And Inference, Peter C. B. Phillips, Igor L. Kheifets
High-Dimensional Iv Cointegration Estimation And Inference, Peter C. B. Phillips, Igor L. Kheifets
Research Collection School Of Economics
A semiparametric triangular systems approach shows how multicointegrating linkages occur naturally in an I(1) cointegrated regression model when the long run error variance matrix in the system is singular. Under such singularity, cointegrated I(1) systems embody a multicointegrated structure that makes them useful in many empirical settings. Earlier work shows that such systems may be analyzed and estimated without appealing to the associated I(2) system but with suboptimal convergence rates and potential asymptotic bias. The present paper develops a robust approach to estimation and inference of such systems using high dimensional IV methods that have appealing asymptotic properties like those …
Subjective Socioeconomic Status Moderates How Resting Heart Rate Variability Predicts Pain Response, Jacinth Jia Xin Tan, Chin Hong Tan, Michael W. Kraus
Subjective Socioeconomic Status Moderates How Resting Heart Rate Variability Predicts Pain Response, Jacinth Jia Xin Tan, Chin Hong Tan, Michael W. Kraus
Research Collection School of Social Sciences
Higher resting heart rate variability (HRV)—an index of more flexible response to environmental stressors, including noxious stimuli—has been linked to reduced perception of experimentally induced pain. However, as stress responses are adapted to one’s chronic environments, we propose that chronic exposure to threats captured by one’s subjective socioeconomic status (SSS) may shape different adaptations that produce distinct pain responses linked to higher resting HRV. Specifically, lower SSS individuals with more threat exposures may prioritize threat detection by upregulating sensitivity to stressors, such as acute pain. Therefore, higher HRV would predict greater perceived acute pain among lower SSS individuals. In contrast, …
Effects Of Voice Pitch On Social Perceptions Vary With Relational Mobility And Homicide Rate, Toe Aung, Et. Al
Effects Of Voice Pitch On Social Perceptions Vary With Relational Mobility And Homicide Rate, Toe Aung, Et. Al
Research Collection School of Social Sciences
Fundamental frequency (fo) is the most perceptually salient vocal acoustic parameter, yet little is known about how its perceptual influence varies across societies. We examined how fo affects key social perceptions and how socioecological variables modulate these effects in 2,647 adult listeners sampled from 44 locations across 22 nations. Low male fo increased men’s perceptions of formidability and prestige, especially in societies with higher homicide rates and greater relational mobility in which male intrasexual competition may be more intense and rapid identification of highstatus competitors may be exigent. High female fo increased women’s perceptions of flirtatiousness where relational mobility was …
Geographies Of Storage, Sayd Randle
Geographies Of Storage, Sayd Randle
Research Collection College of Integrative Studies
Resource storage has long played a key role in the production of socio-ecological arrangements and economic relations. Even so, storage as a concept has remained somewhat marginal within geographical scholarship, often obscured by an analytical focus on the dynamics of movement. Reviewing recent works from geography, science and technology studies, and anthropology that center sites and practices of storage, this essay elaborates the diverse ways in which storage arrangements mediate resource circulation and the production of space. This literature demonstrates that thinking systematically with storage can illuminate a range of novel temporal, material, and value entanglements in-the-making, pointing to potentially …

Singapore International Dispute Resolution Academy
Purpose: This paper aims to determine the types of legal mechanisms that authorities can use to recover stolen assets for and from China. Design/methodology/approach: Newspaper articles and books are examined as are relevant reports by various regulatory authorities and academic institutions. Findings: The effectiveness of legal mechanisms in the recovery of stolen assets may be affected by issues such as the difficulties in tracing illicit funds, the ambiguous nature of “value” as well as the rise in technology. Research limitations/implications: There are limited data available in relation to the prevalence of corrupt officials along the Belt and Road Initiative and …
Impact Of A Covid-19 Related Lockdown On The Experience Of Informal Caregiving In Singapore, Vicky Mengqi Qin, Abhijit Visaria, Rahul Malhotra
Impact Of A Covid-19 Related Lockdown On The Experience Of Informal Caregiving In Singapore, Vicky Mengqi Qin, Abhijit Visaria, Rahul Malhotra
ROSA Journal Articles and Publications
Introduction: Lockdowns, while limiting COVID-19 transmission, can affect provision of care by informal caregivers and their caregiving experience. We assessed, among informal caregivers in Singapore, (a) the perceived impact of a 2-month (April to May 2020) nationwide lockdown on their care provision, (b) correlates of different perceptions of the impact of the lockdown on care provision, and (c) association of different perceptions of the impact with negative and positive experiences of caregiving. Methods: In the August 2020 wave of the Singapore Life Panel (SLP; nationally representative, longitudinal monthly survey of Singapore citizens and permanent residents aged 50-70 years at baseline), …

Rethinking The Inclusionary Potential Of Religious Institutions: The Case Of Gurdwaras In Singapore, Siew Ying Shee, Orlando Woods
Research Collection College of Integrative Studies
Whilst Singapore’s Sikh community is relatively small, it is also heterogeneous. Its diversity reflects differences in ancestral and socio-economic backgrounds. As spaces of worship that regularly bring together the Sikh community in space and time, Sikh temples—gurdwaras––are often conceived as important places through which a shared sense of religiously-defined community is reproduced. Yet, as much as religion can provide a bridge that integrates people of different ethnic, racial, national, and linguistic groups into a single faith community, so too can it act as a buttress through which differences and divisions are enforced within the community. We argue that whilst gurdwaras …

Social Media And Performative Parenting, Sun Sun Lim, Yang Wang
Research Collection College of Integrative Studies
With the intensifying use of social media in many realms of everyday life, even parenting is manifesting a public dimension. Whereas one might regard parenting as a private activity undertaken within the home, the use of social media to highlight the joys and trials of child-rearing has put parenting under the digital spotlight. Parents are keen to showcase their children’s growth and development to family and friends. Significant achievements invite praise and social endorsement, as well as commendations for excellent parenting. The sharing of parenting struggles over social media can also elicit expressions of commiseration, sympathy and support. The ensuing …

The Effects Of Language-Related Misunderstanding At Work, John Fiset, Devasheesh P. Bhave, Nilotpal Jha
Research Collection Lee Kong Chian School Of Business
Demographic, technological, and global trends have brought the language used at the workplace to the forefront. A growing body of research reveals that language could result in misunderstanding at work, and influence employees' performance and attitudinal outcomes. Language at work encompasses standard language (e.g., English) as well as several hybrid forms of language (non-native accents, code-switching, and jargon). We delineate how these forms of language could result in misunderstanding. We then identify relational, affective, and informational mechanisms that underlie the relationship between language-related misunderstanding and employees' performance and attitudinal outcomes, and highlight key boundary conditions. In doing so, we uncover …

Topic modeling and LDA (Latent Dirichlet Allocation) have proven valuable in various fields as an innovative approach to studying areas of interest and identifying topics in a dynamic content. The underlying assumption is that techniques like LDA can swiftly capture emerging topics in textual documents compared to other categorization tools. These unsupervised approaches have been used to identify new industries and technological domains. However, our study on the nascent topic of “sustainability” within the corpora of SGX-listed companies highlights clear limitations in employing techniques like LDA on sparse data. The dynamic LDA approach, also called DTM (Dynamic Topic Modelling),based on …
Market For Manipulable Information, Hui Chen, Jian Sun
Market For Manipulable Information, Hui Chen, Jian Sun
Research Collection Lee Kong Chian School Of Business
We study how investors, firms, and information sellers interact in a market with manipulable information. To better predict the firm characteristics they care about, investors can buy a score from a monopolistic information seller, which aggregates signals that are subject to firm manipulation. The average degree of signal manipulability has no effect on the equilibrium, while the uncertainty about manipulability becomes a new source of noise. Its contribution depends on firms' incentive to manipulate the signals, which in turn depends on the equilibrium price sensitivity to the score. The optimal design of the score weighs signal precision against the endogenous …

Equal Predictive Ability Tests Based On Panel Data With Applications To Oecd And Imf Forecasts, Oguzhan Akgun, Alain Pirotte, Giovanni Urga, Zhenlin Yang
Research Collection School Of Economics
We propose two types of equal predictive ability (EPA) tests with panels to compare the predictions made by two forecasters. The first type, S-statistics, focuses on the overall EPA hypothesis, which states that the EPA holds, on average, over all panel units and over time. The second type, C-statistics, focuses on the clustered EPA hypothesis where the EPA holds jointly for a fixed number of clusters of panel units. The asymptotic properties of the proposed tests are evaluated under weak and strong cross-sectional dependence. An extensive Monte Carlo simulation shows that the proposed tests have very good finite sample properties, …
