Socializing Targets Of Older Adults’ Sns Use: Social Strain Mediates The Relations Between Older Adults’ Sns Use With Friends And Well-Being Outcomes, Yue Qi Germaine Tng, Hwajin Yang

Research Collection School of Social Sciences

Studies have yielded mixed findings regarding the relation between older adults’ social networking site (SNS) use and well-being. Drawing on socioemotional selectivity theory, we sought to examine whether older adults’ SNS use with different socializing targets (i.e., family vs friends) would differentially predict global, social, and mental well-being outcomes indexed by life satisfaction, loneliness, and depressive symptoms, respectively. Furthermore, we examined whether social support and social strain would mediate, in parallel, the relations between SNS use and well-being outcomes. We recruited healthy, community-dwelling older adults (ages 60–93 years, N = 69). Using the PROCESS macro, we found that SNS use …

Help-Seeking Tendencies And Subjective Well-Being: A Cross-Cultural Comparison Of The United States And Japan, Verity Yu Qing Lua, Nadyanna Binte Mohamed Majeed, Andree Hartanto, Angela K. Y. Leung

Research Collection School of Social Sciences

Help-seeking is commonly conceived as an instrumental behavior that improves people’s subjective well-being. However, most findings supporting a positive association between help-seeking and subjective well-being are observed in independence-preferring countries. Drawing from research demonstrating that the pathways to subjective well-being are culturally divergent, we posit that help-seeking tendencies may be detrimental to subjective well-being for members in interdependence-preferring countries where norms for preserving relational harmony and face concerns are prevalent. This study tested the moderating role of country in the relationship between help-seeking tendencies and subjective well-being using data from 5,068 American and Japanese participants. Results revealed that although help-seeking …

Regional Mapping: Digital Provisions Play A Key Role In Asia Pacific Agreements, Henry S. Gao

Research Collection Yong Pung How School Of Law

IT HAS become more commonplace for trade agreements in the Asia Pacific to include a variety of digital trade provisions. To understand the salient features of these agreements, it is helpful to map out their main baseline features. Doing so also indicates where digital trade agreements may be going or need to go. This mapping covers all free trade agreements (FTAs) with chapters on e-commerce or digital trade since 2000 by the main players in the region-China, South Korea, Japan, India, Australia, New Zealand, Singapore, Vietnam and Malaysia.

The Torrens System In Singapore: 75 Years From Conception To Commencement, Alvin W. L. See

Research Collection Yong Pung How School Of Law

This article tells the story of how the Torrens system of land titles registration came to be adopted in Singapore. From conception to commencement, the entire process took over 75 years, far longer than any other law reform the country has experienced. Particular attention is paid to why the Australian model was preferred despite the significant influence of English law in colonial Singapore. Although as with anything, much of what happened could be attributed to chance, a great deal can be learned from this story, which details the socio-economic and political forces that have shaped the law into what it …

Trust In Robotics: A Multi-Staged Decision-Making Approach To Robots In Community, Wenxi Zhang, Willow Wong, Mark Findlay

Centre for AI & Data Governance

Pivoting on the desired outcome of social good within the wider robotics ecosystem, trust is identified as the central adhesive of the HRI interface. However, building trust between humans and robots involves more than improving the machine’s technical reliability or trustworthiness in function. This paper presents a holistic, community-based approach to trust-building, where trust is understood as a multifaceted and multi-staged looped relation that depends heavily on context and human perceptions. Building on past literature that identifies dispositional and learned stages of trust, our proposed Decision to Trust model considers more extensively the human and situational factors influencing how trust …

Reflection On Wise Cities And Ai In Community: Sustainable Life Spaces And Kampung Storytelling, Mark Findlay, Li Min Ong

Centre for Commercial Law in Asia

This short paper is a reflection following our presentation made at the ASEAN Law Research Network’s conference on Sustainable Development and Commerce in ASEAN Cities. We had wanted to introduce our thinking, given the strong interest in developing smart cities in the region. We want to emphasise the importance of multidisciplinary approaches in the sustainable development of cities, particularly the voice of social scientists which tends to get left out in discussions over technology. In the race towards “smart” urbanisation, there is a real risk that history and culture – things that give a city “life” – could get decimated …

Note To Self: How I Can Be A Better Reviewer?, Reddi Kotha

Research Collection Lee Kong Chian School of Business

In this article I review some of the common errors I have made as a reviewer and suggest ways to avoid them.The progress of science depends on reviewers as much as it depends upon researchers developing new science. Reviewers provide impartial, anonymous, and expert advice to researchers, and they screen which research gets published in scientific journals. When the review process works well, it acts as an effective filter and enables dissemination of high-quality and rigorous scientific work. As so much of scientific progress depends upon review, it is surprising that reviewers learn this science by doing. Of course, there …

The Hunger Report Part Ii: Targeting Specific Needs In The Wake Of Covid-19, Dalvin Sidhu, Tania Nagpaul, Weng Lin Ng, Thilanga Dilum Wewalaarachchi

Lien Centre for Social Innovation: Research

The Hunger Report Part II: Targeting Specific Needs in the Wake of COVID-19 is the first intervention study of its kind in Singapore, delving into how the food situation of previously identified food-insecure households has changed during the COVID-19 pandemic. Through surveys, this report reveals the impact COVID-19 has had on a small sample of food-insecure families in Singapore. The authors also administer a Needs Toolkit to understand the unique needs and preferences of each food-insecure household. They then explore the impact of autonomy in food support through an intervention element in the study

Geopolitics And Ballpark Estimates, Thomas Lam, David Fernandez

Sim Kee Boon Institute for Financial Economics

Most economist commenced 2022 with 3 key assumptions on the global economy:

1) Some policy normalisation and reversal, though cautious and uneven, are likely to occur in economies with above-average growth and inflation;

2) The Covid-19 infection wave, while presumably asymmetric and recurrent across countries, appears to have less of an imprint on cyclical activity on balance;

3) The lingering supply disruptions resulting from the pandemic, albeit still intense and widespread, should be easing gradually.

A Posterior-Based Wald-Type Statistic For Hypothesis Testing, Yong Li, Xiaobin Liu, Tao Zeng, Jun Yu

Research Collection School Of Economics

A new Wald-type statistic is proposed for hypothesis testing based on Bayesian posterior distributions under the correct model specification. The new statistic can be explained as a posterior version of the Wald statistic and has several nice properties. First, it is well-defined under improper prior distributions. Second, it avoids Jeffreys–Lindley–Bartlett’s paradox. Third, under the null hypothesis and repeated sampling, it follows a χ2" role="presentation" style="box-sizing: border-box; margin: 0px; padding: 0px; display: inline-block; line-height: normal; font-size: 16.2px; word-spacing: normal; overflow-wrap: normal; white-space: nowrap; float: none; direction: ltr; max-width: none; max-height: none; min-width: 0px; min-height: 0px; border: 0px; position: relative;">χ2 …

Toward An Environmentally Sustainable City In The Light Of Industrial Revolution 4.0: A Case Study Of Ho Chi Minh City, Tran Viet Dung

Centre for Commercial Law in Asia

Like other large cities in ASEAN, Vietnamese cities have been facing serious urban environment problems such as air pollution, land degradation, weak water drainage and lack of green spaces. These problems are caused by unsustainable patterns of development. City governments have failed to coordinate and integrate city planning consistently. Trends show that governments prefer to take short-term economic profit rather than focus on environmental protection.

Legal Challenges And Opportunities For Peer-To-Peer Electricity Trading In Thailand, Piti Eiamchamroonlarp

Centre for Commercial Law in Asia

Electricity is a critical resource for a country as it powers devices and enables modern living with digital transactions, crypto mining, deployment of electric vehicles (EV) etc. Given these emerging activities, electricity demand is forecasted to keep rising. The peak electricity load in Thailand for 2018, 29,969 MW, will likely increase to 53,997 MW by 2037. However, Thailand, as a party to the United Nations Framework Convention on Climate Change, must consider negative impacts on the environment from electricity generation. To meet these challenges, renewable resources are needed for cleaner electricity generation and ensuring security of electricity supply, while simultaneously …

Indonesia's Termination Of Bilateral Investment Treaties, Lucas Jun Hao Wong

Centre for Commercial Law in Asia

Indonesia holds a vast source of untapped potential in terms of its ability to influence global trade. While Indonesia has been a member of the World Trade Organization (WTO) since 1 January 1995, its integration into global value chains remains relatively weak, with the ratio of its trade in goods and services to GDP falling from 48.6% in 2013 to below 40% in 2019. Nonetheless, as Southeast Asia’s largest economy and a member of the G20, Indonesia possesses the capacity to become a key player on the world stage.

On The Test Accuracy And Effective Control Of The Covid-19 Pandemic: A Case Study In Singapore, Guang Cheng, Sarah Yini Gao, Yancheng Yuan, Chenxiao Zhang, Zhichao Zheng

Research Collection Lee Kong Chian School Of Business

This study examines the impact of coronavirus disease 2019 (COVID-19) test accuracy (i.e., sensitivity and specificity) on the progression of the pandemic under two scenarios of limited and unlimited test capacity. We extend the classic susceptible–exposed–infectious–recovered model to incorporate test accuracy and compare the progression of the pandemic under various sensitivities and specificities. We find that high-sensitivity tests effectively reduce the total number of infections only with sufficient testing capacity. Nevertheless, with limited test capacity and a relatively high cross-infection rate, the total number of infected cases may increase when sensitivity is above a certain threshold. Despite the potential for …

Financial Intermediaries And Contagion In Market Efficiency: The Case Of Etfs, Claire Yurong Hong, Frank Weikai Li, Avanidhar Subrahmanyam

Research Collection Lee Kong Chian School Of Business

Capital constraints of financial intermediaries can affect liquidity provision. We investigate whether these constraints spillover and consequently cause contagion in the degree of market efficiency across assets managed by a common intermediary. Specifically, we provide evidence of strong comovement in pricing gaps between ETFs and their constituents for ETFs served by the same lead market maker (LMM). The effects are stronger for ETFs that are more illiquid and volatile, when the underlying constituents of the ETFs are more costly to arbitrage, and for LMMs with more constrained capital. Using extreme disruptions in debt markets during COVID-19 as an experiment, we …

How Do Firms Respond To Reduced Private Equity Buyout Activity?, Yi-Hsin Lo

Research Collection Lee Kong Chian School Of Business

This paper presents new evidence on the economic role of private equity buyouts by exploiting the staggered adoption of the constructive fraud provision by U.S. state courts. The law unintentionally shifts the credit default risk borne by existing unsecured creditors of the buyout target to the selling shareholders and lenders in the form of ex-post litigation risk, thereby discouraging buyout activity. Using a difference-in-differences framework, I find that firms raise less capital, reduce payouts and investments, and form alliances with employees. Firms also avoid positive NPV projects that carry too much risk. These findings are consistent with managers enjoying a …

Does The Dna Of Business Schools Need To Change?, Arnoud Cyriel Leo De Meyer

Research Collection Lee Kong Chian School Of Business

The causes, effects and consequences concern corporate governance and organisational management as much as political conflict, environmental sustainability and foreign diplomacy. In Business Schools on an Innovation Mission, a report released by the Association to Advance Collegiate Schools of Business in May 2010, management and leadership were clearly positioned, side-by-side with science and technology, as vital components to the innovation value chain. The business world exists as an eco-system of business, government, NGOs and non-profits, each interlocking. To be truly a "School for Business" it is also important to build strong relationships and strategic partnerships with the business world. In …

Correlation-Robust Auction Design, Wei He, Jiangtao Li

Research Collection School Of Economics

We study the design of auctions when the auctioneer has limited statistical information about the joint distribution of the bidders' valuations. More specifically, we consider an auctioneer who has an estimate of the marginal distribution of a generic bidder's valuation but does not have reliable information about the correlation structure. We analyze the performance of mechanisms in terms of the revenue guarantee, that is, the greatest lower bound of revenue across all joint distributions that are consistent with the marginals. A simple auction format, the second-price auction with no reserve price, is shown to be asymptotically optimal, as the number …

The CSISG serves as a quantitative benchmark of the quality of goods and services produced by the Singapore economy over time and across countries. The fourth quarter results mark the end of measurement for CSISG 2019. Singapore’s 2019 national score was computed using the data collected during these four quarters.

Gender Role Ideology And Implications For Well-Being Among Older Adults In Singapore, Nadya Haifan, Erra Natalia Sayri, Micah Tan, Mindy Eiko Tadai

ROSA Research Briefs

Gender role ideology, referring to the attitudes that individuals hold with respect to the social roles that different genders should adopt, have been suggested to affect the mental well-being (e.g., Paul & Moser, 2009; Sweeting, 2014) and marital satisfaction (e.g., Amato et al., 2007; Davis & Greenstein, 2009) of individuals. Despite this, gender role ideology and the impact they may have on well-being is understudied among older adults in Singapore. Given this, the current report provides a brief examination of gender role ideology among older adults in Singapore. This includes the following: 1. The demographic distribution of gender role ideology …

Volunteerism Among Older Adults In Singapore, Micah Tan, John Frederic Pedro Ortega, Nur Syafiqah Abdullah, Mindy Eiko Tadai, Rachel Wen Yi Ngu

ROSA Research Briefs

Volunteerism is recognised as a beneficial activity for individuals for many reasons. Beyond the potential of volunteerism to create new and meaningful communities (Hodge et al., 2013), it offers numerous benefits including improvement to one’s mental health (Willigen, 2000), self-esteem (Russell et al., 2018), and social connectedness (Hodge et al., 2013). Volunteering has also been found to provide a sense of purpose in one’s life (Schwingel et al., 2009). For these reasons and more, voluntary work among older adults may be a meaningful and effective pathway towards successful ageing, particularly for those in retirement. In Singapore, the National Volunteer and …

Heterogeneous Attentions For Solving Pickup And Delivery Problem Via Deep Reinforcement Learning, Jingwen Li, Liang Xin, Zhiguang Cao, Andrew Lim, Wen Song, Jie Zhang

Research Collection School Of Computing and Information Systems

Recently, there is an emerging trend to apply deep reinforcement learning to solve the vehicle routing problem (VRP), where a learnt policy governs the selection of next node for visiting. However, existing methods could not handle well the pairing and precedence relationships in the pickup and delivery problem (PDP), which is a representative variant of VRP. To address this challenging issue, we leverage a novel neural network integrated with a heterogeneous attention mechanism to empower the policy in deep reinforcement learning to automatically select the nodes. In particular, the heterogeneous attention mechanism specifically prescribes attentions for each role of the …

Estimating Financial Information Asymmetry In Real Estate Transactions In China: An Application Of Two-Tier Frontier Model, Ganlin Pu, Ying Zhang, Li-Chen Chou

Research Collection School Of Computing and Information Systems

This study applies the two-tier stochastic frontier model to estimate the distribution of housing transaction information in Hangzhou, Wenzhou, Ningbo, and Jinhua (four cities in Zhejiang Province, China) during the year 2018, to analyze the difference in the price information acquired by the buyers and sellers in the transaction, and the effect of information asymmetry on the transaction price. The empirical results show that in each city, during the housing transaction process, the supplier has more complete information about house prices than consumers, and can therefore implement price discrimination strategies in setting service prices. Due to the disadvantage in acquired …

The Impact Of Ride-Hail Surge Factors On Taxi Bookings, Sumit Agarwal, Ben Charoenwong, Shih-Fen Cheng, Jussi Keppo

Research Collection School Of Computing and Information Systems

We study the role of ride-hailing surge factors on the allocative efficiency of taxis by combining a reduced-form estimation with structural analyses using machine-learning-based demand predictions. Where other research study the effect of entry on incumbent taxis, we use higher frequency granular data to study how location-time-specific surge factors affect taxi bookings to bound the effect of customer decisions while accounting for various confounding variables. We find that even in a unique market like Singapore, where incumbent taxi companies have app-based booking systems similar to those from ride-hailing companies like Uber, the estimated upper bound on the cross-platform substitution between …
