Mate Preference Priorities In The East And West: A Cross-Cultural Test Of The Mate Preference Priority Model, Andrew G. Thomas, Peter K. Jonason, Jesse D. Blackburn, Leif E. O. Kennair, Rob Lowe, John Malouff, Steve Stewart-Williams, Danielle Sulikowski, Norman P. Li

Research Collection School of Social Sciences

Objective: Mate choice involves trading-off several preferences. Research on this process tends to examine mate preference prioritization in homogenous samples using a small number of traits and thus provide little insight into whether prioritization patterns reflect a universal human nature. This study examined whether prioritization patterns, and their accompanying sex differences, are consistent across Eastern and Western cultures. Method: In the largest test of the mate preference priority model to date, we asked an international sample of participants (N = 2,477) to design an ideal long-term partner by allocating mate dollars to eight traits using three budgets. Unlike previous versions …

Strategic Alliances As Treatment For Covid-19 And Beyond, Theodor Florian Cojoianu, Aoife Brophy Haney, Alet Meiring

Research Collection College of Integrative Studies

Novel strategic alliances have been emerging quickly in response to the Covid-19 crisis. We know much at alliance and firm-level about the benefits and challenges associated with different types of alliance configurations, however there are still gaps in our knowledge about the connection between alliances and impacts on society and the environment. In this paper, we use a novel dataset of 217 strategic alliances that have emerged between January and April 2020 in response to the Covid-19 crisis. We analyze which alliances have emerged and how these alliances are tackling different needs related to the crisis. We find that alliances …

Minding Other People's Business: Community Attachment And Anticipated Negative Emotion In An Extended Norm Activation Model, Sonny Rosenthal, Kang Leng Ho

Research Collection College of Integrative Studies

This study extended the norm activation model in the context of litter reduction to explain self-managing (e.g., avoiding littering) and other-managing (e.g., picking up litter) behaviors. Although those kinds of behaviors are conceptually distinct, prior research has not explained differences in their prediction. This study addresses that gap by considering the roles of community attachment and anticipated negative emotion in other-managing behavior. The addition of those predictors creates a second explanatory pathway in the norm activation model. Results showed awareness of consequences, ascription of responsibility, and community attachment predicted personal norm (R2 = 0.54), which predicted self-managing behavior (R2 = …

In 2010, Singapore Management University (SMU) was just 10 years old with aspirations to keep growing and attain a global reputation. But how could the University highlight the hard work taking place in its schools and institutes? A core group of stakeholders decided that a digital repository was crucial to making the institution’s intellectual output openly discoverable in order to achieve a more globally visible profile. This case study shares SMU’s journey, as well as tips that can help other young institutions launch a digital repository and open their research and scholarship to discovery by the world.

Living And Learning In A Lockdown: 5 Ways To Stay Productive And Entertained At Home, Ishan Singh

Social Space

If nothing else, the COVID-19 pandemic has taught me that staying at home is tougher than it seems. For introverts like myself, hunkering indoors should come naturally—even pre-coronavirus, I didn't get out a whole lot. Yet the experience has turned out to be very different when hanging out at home becomes less of a pastime and more of national responsibility.

Privilege In A Pandemic: An International Student's Perspective, Athena Macatangay

Social Space

And just like that, Singapore is approaching the end of its national circuit breaker.

These days, my university dorm has become my little universe. With COVID-19 showing no signs of abating, my schoolmates and I have been spending our semester break indoors. All the action takes place within the four walls of my room, where I clock my hours at a virtual internship, read, exercise and FaceTime with friends and family.

Nurturing Societal Leadership: Activities As Building Blocks, Simon Mckenzie, Jane Sassienie, Sunil Savara

Social Space

We previously discussed the importance of societal leadership in building a better world for future generations—and how societal leaders are driven by a purpose far greater than themselves. In the first article, we introduced the Bridge Societal Leadership Model and outlined the common beliefs observed in many societal leaders. In the second article, we examined their common capacities, such as their remarkable abilities and capabilities.

Beyond Physical Entrainment: Competitive And Cooperative Mental Stances During Identical Joint-Action Tasks Differently Affect Inter-Subjective Neural Synchrony And Judgments Of Agency, Philip S. Cho, Nicolas Escoffier, Yinan Mao, Christopher Green, Richard C. Davis

Research Collection School Of Computing and Information Systems

Little work has examined how mental stance alone, apart from physical entrainment, affects between-participant neural synchrony during joint social interaction. We report the first findings on how cooperative and competitive mental stances, even during identical visuomotor joint-action tasks, result in distinct neural oscillatory signatures in low beta and theta band between-participant phase synchrony. Two participants jointly controlled a cursor and were instructed to either compete or cooperate to move it to one of three targets. The visuomotor output was identical for both the compete and cooperate conditions because participants were privately given the same target for experimental trials. Cooperation enhanced …

Competitive Ratios For Online Multi-Capacity Ridesharing, Meghna Lowalekar, Pradeep Varakantham, Patrick Jaillet

Research Collection School Of Computing and Information Systems

In multi-capacity ridesharing, multiple requests (e.g., customers, food items, parcels) with different origin and destination pairs travel in one resource. In recent years, online multi-capacity ridesharing services (i.e., where assignments are made online) like Uber-pool, foodpanda, and on-demand shuttles have become hugely popular in transportation, food delivery, logistics and other domains. This is because multi-capacity ridesharing services benefit all parties involved – the customers (due to lower costs), the drivers (due to higher revenues) and the matching platforms (due to higher revenues per vehicle/resource). Most importantly these services can also help reduce carbon emissions (due to fewer vehicles on roads). …

A window of opportunity for intervention is the predementia stage known as mild cognitive impairment (MCI). Individuals often present to services late in the course of their disease and more needs to be done for early detection; sensor technology is a potential method for detection.Objective: The aim of this cross-sectional study was to establish the feasibility and acceptability of utilizing sensors in the homes of senior citizens to detect changes in behaviors unobtrusively.Methods: We recruited 59 community-dwelling seniors (aged >65 years …

Route Choice Behaviour And Travel Information In A Congested Network: Static And Dynamic Recursive Models, Giselle De Moraes Ramos, Tien Mai, Winnie Daamen, Emma Frejinger

Research Collection School Of Computing and Information Systems

Travel information has the potential to influence travellers choices, in order to steer travellers to less congested routes and alleviate congestion. This paper investigates, on the one hand, how travel information affects route choice behaviour, and on the other hand, the impact of the travel time representation on the interpretation of parameter estimates and prediction accuracy. To this end, we estimate recursive models using data from an innovative data collection effort consisting of route choice observation data from GPS trackers, travel diaries and link travel times on the overall network. Though such combined data sets exist, these have not yet …

Hierarchical Multiagent Reinforcement Learning For Maritime Traffic Management, Arambam James Singh, Akshat Kumar, Hoong Chuin Lau

Research Collection School Of Computing and Information Systems

Increasing global maritime traffic coupled with rapid digitization and automation in shipping mandate developing next generation maritime traffic management systems to mitigate congestion, increase safety of navigation, and avoid collisions in busy and geographically constrained ports (such as Singapore's). To achieve these objectives, we model the maritime traffic as a large multiagent system with individual vessels as agents, and VTS (Vessel Traffic Service) authority as a regulatory agent. We develop a hierarchical reinforcement learning approach where vessels first select a high level action based on the underlying traffic flow, and then select the low level action that determines their future …

Developing Online Business Strategy With Millennials Through Partnership With University, Yuanto Kusnadi, Gary Pan

Research Collection School Of Accountancy

The COVID-19 pandemic has brought about a significant shift in shopping behaviour from offline to online among Singaporean consumers. According to data from data analytics firm Nielsen, 37 per cent of Singaporean consumers have increased online shopping activities since the COVID-19 outbreak. This shift towards online shopping, food delivery and e-groceries may persist beyond the COVID-19 period. While the increase in online shopping has benefited online stores, many businesses who do not yet have an online presence or have not been paying much attention to conducting sales online were caught off-guard during the circuit breaker period which has resulted in …

Essays On Corporate Social Responsibility And Strategic Leadership, Li Tong

Dissertations and Theses Collection (Open Access)

This dissertation two issues related to business ethics: how corporate social responsibility (CSR) affects the value creation in an acquisition and how corporate decoupling behaviors are driven by the CEO narcissism, consisting of two essays. The first essay examines how target corporate social responsibility affects the economic gains for acquirers, as reflected in market reaction to acquisition announcement, from two distinct perspectives: stakeholder preservation versus stakeholder appropriation. The stakeholder preservation perspective suggests that positive market reaction to an acquisition stems from potential new value creation by honoring implicit contracts and maintaining good relationships with target stakeholders. By contrast, the stakeholder …

Is It Only The Thought That Counts; Or Do Gift Cost, Social Approval, And Relationship Satisfaction Matter Too?, Farah Binte Abdul Malik

Dissertations and Theses Collection (Open Access)

This study investigated the effects of gift cost, social network (SN) approval, and relationship satisfaction on a gift receiver’s perception of the giver’s commitment to their romantic relationship. In addition to predictions of positive main effects (H1 to H3), it was predicted that relationship satisfaction would moderate the effects of gift cost (H4) and SN approval (H5). Participants were 227 undergraduates from Singapore who completed a survey online. A hierarchical moderated regression analysis was conducted, and the results supported all the hypotheses except H5. The novel findings were that receivers perceived their partners to be more committed when their SN …

Three Essays On Quality Of Tradable Products, Angdi Lu

Dissertations and Theses Collection (Open Access)

This dissertation includes three essays on the quality of tradable products. The first chapter studies the supply-side determinants of quality specialization across Chinese cities. Specifically, we complement the quality specialization literature in international trade and study how larger cities within a country produce goods with higher quality. In our general equilibrium model, firms in larger cities specialize in higher-quality products because agglomeration benefits (arising from the treatment effect of agglomeration and firm sorting) accrue more to skilled workers, who are also more efficient in upgrading quality, although these effects are partially mitigated by higher skill premium in larger cities. Using …

Three Essays On Financial Economics, Jiangyuan Li

Dissertations and Theses Collection (Open Access)

Disagreement measures are known to predict cross-sectional stock returns but fail to predict market returns. This paper proposes a partial least squares disagreement index by aggregating information across individual disagreement measures and shows that this index significantly predicts market returns both in- and out-ofsample. Consistent with the theory in Atmaz and Basak (2018), the disagreement index asymmetrically predicts market returns with greater power in high sentiment periods, is positively associated with investor expectations of market returns, predicts market returns through a cash flow channel, and can explain the positive volume-volatility relationship.

Essays On Heterogeneous Large Panel Data Models, Ke Miao

Dissertations and Theses Collection (Open Access)

This dissertation consists of three papers which contribute to the estimation and inference theory of the heterogeneous large panel data models. The first chapter studies a panel threshold model with interactive fixed effects. The least-squares estimators in the shrinking-threshold-effect framework are explored. The inference theory on both slope coefficients and the threshold parameter is derived, and a test for the presence of the threshold effect is proposed. The second chapter considers the least-squares estimation of a panel structure threshold regression (PSTR) model, where parameters may exhibit latent group structures. Under some regularity conditions, the latent group structure can be correctly …

Essays On Agricultural Commodity Processing, Bin Li

Dissertations and Theses Collection (Open Access)

This dissertation investigates two important issues in agricultural commodity processing: (i) biomass commercialization; that is, converting organic waste into a saleable product, from economic and environmental perspectives, and (ii) optimal procurement portfolio design using multiple suppliers and spot market, and the impact of by-product introduction on this optimal portfolio.

The first chapter examines the economic implications of biomass commercialization from the perspective of an agri-processor that uses a commodity input to produce both a commodity output and biomass. We characterize the value of biomass commercialization and perform sensitivity analysis to investigate how spot price uncertainty (input and output spot price …

The Development Of Singapore Law: A Bicentennial Retrospective, Andrew Phang, Yihan Goh, Jerrold Soh

Research Collection Yong Pung How School Of Law

The present article reviews (in broad brushstrokes) the status of Singapore law during its bicentennial year. It is not only about origins but also about growth – in particular, the autochthonous or indigenous growth of the Singapore legal system (particularly since the independence of Singapore as a nation state on 9 August 1965). The analysis of this growth is divided into quantitative as well as qualitative parts. In particular, the former constitutes an empirical analysis which attempts – for the very first time − to tell the development of Singapore law through numbers, building on emerging techniques in data visualisation …

‘Living In A State Of Filth And Indifference To … Their Health’: Weather, Public Health And Urban Governance In Colonial George Town, Penang, Fiona Williamson, Katrina Proust

Research Collection School of Social Sciences

This article explores the development of public health infrastructure in George Town, Penang, before the 1930s. It argues that the extreme weather of the tropical climate led to a unique set of health challenges for George Town’s administrators, as the town grew from a small British base to a multi-cultural and thriving port. Weather and public health were (and still are) integrally connected,although the framing of this relationship has undergone significant shifts in thinking and appearance over time. One lens into this association is the situation and expression of these elements within municipal structures.During the nineteenth century, government departments were …
