Resource Capacity Requirement For Multi-Terminal Cooperation In Container Ports, Byung Kwon Lee, Mei Wan Low Oct 2021

Resource Capacity Requirement For Multi-Terminal Cooperation In Container Ports, Byung Kwon Lee, Mei Wan Low

Research Collection Lee Kong Chian School Of Business

Capacity sharing among neighboring terminals offer a means to meet increasing or unexpected demand for cargo-handling without additional capital investment. This study proposes a model for capacity requirement planning of major resources, such as quay cranes (QCs), storage space, and gate, in multiterminal port operations where demand is time dependent. A resource profile simulation is run to generate random events across the terminals and estimate the capacity requirement in the form of workload distributions on port resources over time-shifts. The effects on workload requirement, arising from multiterminal cooperation, are subsequently evaluated in consideration of different container flows among terminals. Experimental …

What Makes Employees Feel Empowered To Speak Up?, Shilpa Madan, Kevin Nanakdewa, Krishna Savani, Hazel Rose Markus

Research Collection Lee Kong Chian School Of Business

Most managers understand that empowering employees to voice their opinions can help companies innovate and uncover their own shortcomings. However, this understanding does not seem to translate into action. Research shows that over 85% of employees remain silent on crucial matters because they worry about being viewed negatively. How can managers encourage employees to speak their minds at work? The authors’ new research identified a novel method to encourage employees to exercise their voice: creating a company culture that emphasizes the idea of choice. They found that employees were more likely to share their ideas and opinions at a company …

Barking Without Biting: Understanding Chinese Media Campaigns During Foreign Policy Disputes, Frances Yaping Wang Oct 2021

Barking Without Biting: Understanding Chinese Media Campaigns During Foreign Policy Disputes, Frances Yaping Wang

Research Collection School of Social Sciences

What motivates Chinese media campaigns during foreign policy disputes and how are they carried out? “Influence campaigns” are often recognized as highly pertinent to international security, yet they remain understudied. This paper develops and tests a theory that explains these media campaigns as strategic actions to align domestic public opinion when it deviates from the state’s preferred foreign policy, exploiting the media’s mobilization or pacification effect. These divergent media effects correspond to two types of media campaigns respectively – the mobilization campaigns and the pacification campaigns. The pacification campaigns are particularly important because they indicate that hawkish rhetoric may counterintuitively …

Improving The Performance Of Transportation Networks: A Semi-Centralized Pricing Approach, Zhiguang Cao, Hongliang Guo, Wen Song, Kaizhou Gao, Liujiang Kang, Xuexi Zhang, Qilun Wu Oct 2021

Improving The Performance Of Transportation Networks: A Semi-Centralized Pricing Approach, Zhiguang Cao, Hongliang Guo, Wen Song, Kaizhou Gao, Liujiang Kang, Xuexi Zhang, Qilun Wu

Research Collection School Of Computing and Information Systems

Improving the performance of transportation network is a crucial task in traffic management. In this paper, we start with a cooperative routing problem, which aims to minimize the chance of road network breakdown. To address this problem, we propose a subgradient method, which can be naturally implemented as a semi-centralized pricing approach. Particularly, each road link adopts the pricing scheme to calculate and adjust the local toll regularly, while the vehicles update their routes to minimize the toll costs by exploiting the global toll information. To prevent the potential oscillation brought by the subgradient method, we introduce a heavy-ball method …

Holding Water For The City: Emergent Geographies Of Storage And The Urbanization Of Nature, Sayd Randle Oct 2021

Holding Water For The City: Emergent Geographies Of Storage And The Urbanization Of Nature, Sayd Randle

Research Collection College of Integrative Studies

In the US West, water stories are often aqueduct stories, narratives of moving the vital resource from one place to another. This paper, in contrast, explores nascent efforts to keep the water still, in the name of helping buffer cities from the anticipated impacts of climate change. Scripted as potential holding sites for an urban water reserve, aquifers and the task of filling them now orient a range of policies and material investments across Southern California. Building on writings that explore the multi-scalar politics of storing and stockpiling vaccines, resources, and lively or uncooperative commodities, this analysis approaches storage as …

Design Of A Two-Echelon Freight Distribution System In Last-Mile Logistics Considering Covering Locations And Occasional Drivers, Vincent F. Yu, Panca Jodiawan, Ming-Lu Hou, Aldy Gunawan

Research Collection School Of Computing and Information Systems

This research addresses a new variant of the vehicle routing problem, called the two-echelon vehicle routing problem with time windows, covering options, and occasional drivers (2E-VRPTW-CO-OD). In this problem, two types of fleets are available to serve customers, city freighters and occasional drivers (ODs), while two delivery options are available to customers, home delivery and alternative delivery. For customers choosing the alternative delivery, their demands are delivered to one of the available covering locations for them to pick up. The objective of 2E-VRPTW-CO-OD is to minimize the total cost consisting of routing costs, connection costs, and compensations paid to ODs …

Social Norms And Fertility, Sunha Myong, Junghae Park, Junjian Yi Oct 2021

Social Norms And Fertility, Sunha Myong, Junghae Park, Junjian Yi

Research Collection School Of Economics

We document three stylized facts on marriage and fertility patterns in East Asian societies: (i) their marriage rates are among the highest in the world, but their total fertility is the lowest; (ii) although they have the lowest total fertility, almost all married women have at least one child; and (iii) almost no single women have any children. As these societies have been influenced by Confucianism over millennia, marriage and fertility decisions are potentially shaped by two social norms: the unequal gender division of childcare and the stigma attached to out-of-wedlock births. We present a model incorporating the two social …

Closeness-Inducing Discussions With A Romantic Partner Increase Cortisol And Testosterone, Kristi Chin, Zachary A. Reese, Esra Ascigil, Lester Sim, Robin S. Edelstein

Research Collection School of Social Sciences

Despite progress in understanding the social neuroendocrinology of close relationship processes, most work has focused on negative experiences, such as relationship conflict or stress. As a result, much less is known about the neuroendocrine implications of positive, emotionally intimate relationship experiences. In the current study, we randomly assigned 105 dating or married couples to a 30-minute semi-structured discussion task that was designed to elicit either high or low levels of closeness. Participants provided pre- and post-task saliva samples (to assess cortisol and testosterone) and post-task reports of self-disclosure, closeness, attraction, positive and negative affect, and stress. Participants found the discussion …

Shifting Employabilities: Skilling Migrants In The Nation Of Emigration, Yasmin Y. Ortiga Oct 2021

Shifting Employabilities: Skilling Migrants In The Nation Of Emigration, Yasmin Y. Ortiga

Research Collection School of Social Sciences

This paper examines how Philippine state agencies sustain its labour-exporting strategies by encouraging aspiring migrants to invest in their own training and education, taking on the responsibility of turning themselves into desirable workers for employers overseas. Based on a document analysis of newspaper articles and Philippine government reports, this paper uses the case of Philippine nursing education to show how the Philippine state alters these discourses of skill when overseas opportunities decline, channelling aspiring migrants sideways to other sectors of the labour market. Discourses of employability justified these career detours to aspiring migrants by assuring them that such experiences will …

Cultural Districts Advocacy Guide, Su Fern Hoe Oct 2021

Cultural Districts Advocacy Guide, Su Fern Hoe

Research Collection School of Social Sciences

Cultural districts strengthen our cities and communities and support the development of thriving places and people. Support for cultural districts is a high-return investment as their value is immense, multi-layered and far-reaching. However, while those benefits are embraced by many, not all believe it. Increasingly, cultural leaders are being challenged to demonstrate how supporting the arts and culture advances other agendas; from attracting investment to fostering liveable communities and enabling public safety.This advocacy guide makes a case for support of cultural districts as a necessity for building thriving places and people. Importantly, it provides a core set of ideas and …

Air Pollution, Behavioral Bias, And The Disposition Effect In China, Jennifer (Jie) Li, Massimo Massa, Hong Zhang, Jian Zhang Oct 2021

Air Pollution, Behavioral Bias, And The Disposition Effect In China, Jennifer (Jie) Li, Massimo Massa, Hong Zhang, Jian Zhang

Research Collection Lee Kong Chian School Of Business

Inspired by the recent health science findings that air pollution affects mental health and cognition, we examine whether air pollution can intensify the cognitive bias observed in the financial markets. Based on a proprietary data set obtained from a large Chinese mutual fund family consisting of complete trading information for more than 773,198 ac-counts in 247 cities, we find that air pollution significantly increases investors' disposition effects. Analysis based on two plausible exogenous variations in air quality (the vast dissi-pation of air pollution caused by strong winds and the Huai River policy) supports a causal interpretation. Mood regulation provides a …

Scaling Smartness, (De)Provincialising The City? The Asean Smart Cities Network And The Translational Politics Of Technocratic Regionalism, Lily Kong, Orlando Woods Oct 2021

Scaling Smartness, (De)Provincialising The City? The Asean Smart Cities Network And The Translational Politics Of Technocratic Regionalism, Lily Kong, Orlando Woods

Research Collection School of Social Sciences

This paper explores the case study of the ASEAN Smart Cities Network (ASCN) to uncover the motivations and potential challenges associated with technocratic regionalism, by which we mean technology-driven forms of regional integration and consolidation. In the case of the ASCN, technocratic regionalism is used to spur urban development through the rollout of smart city plans, policies and projects across Southeast Asia. As such, it is a regional strategy designed to scale smartness, and thus deprovincialise the city by embedding it within transnational flows of capital, ideas and expertise. At the same time, however, already existing urban issues have the …

Teachers Who Complain About Burnout Are Not Bad Teachers, Bek Wuay Tang, Jacinth Jia Xin Tan

Research Collection School of Social Sciences

Psychology tells us it’s natural but wrong to assume teachers aren’t coping well with stress due to their own inability to manage time or be tough, say SMU’s Tang Bek Wuay and Jacinth Tan. A worrying spotlight was recently shone on burnout among teachers. In a Ministry of Education (MOE) engagement survey conducted in June, three in 10 teachers said they could not cope with stress at work.

Interactional Effects Of Multidimensional Perfectionism And Cognitive Emotion Regulation Strategies On Eating Disorder Symptoms In Female College Students, Germaine Y. Q. Tng, Hwajin Yang Oct 2021

Interactional Effects Of Multidimensional Perfectionism And Cognitive Emotion Regulation Strategies On Eating Disorder Symptoms In Female College Students, Germaine Y. Q. Tng, Hwajin Yang

Research Collection School of Social Sciences

Given the inconclusive findings regarding the relation between perfectionism and eating disorder symptoms, it is important that we determine whether this relation is modulated by emotion dysregulation, which is a prominent risk factor for eating disorders. We sought to identify specific cognitive emotion regulatory strategies—rumination, self-blame, and catastrophizing—that interact with multidimensional perfectionism to shape eating disorder symptoms (i.e., shape, weight, eating concerns, and dietary restraint). Using latent moderated structural equation modeling, we analyzed data from 167 healthy young female adults. We found that only rumination significantly moderated the relation between socially prescribed perfectionism and eating disorder symptoms. However, this was …

Analysis Of Factors Influencing The Bailout Of Distressed Enterprises By Local Asset Management Companies, Houwen Li

Dissertations and Theses Collection (Open Access)

In recent years, the number of distressed enterprises in China has gradually increased due to radical enterprise strategies, excessive expansion, poor management, and a trend of accelerating growth. Unable to adapt to fierce market competition, a large number of “zombie enterprises” disrupt the market order, reduce the use efficiency of social resources, and aggravate market risks. However, some enterprises are
temporarily caught in financial distress due to a deterioration of their financial situation caused by factors such as debt structure or capital liquidity. If such enterprises can be bailed out in time, they can escape their distress, which not only …

The Price Elasticity Of African Elephant Poaching, Quy-Toan Do, Andrei A. Levchenko, Lin Ma, Julian Blanc, Holly Dublin, Tom Milliken Oct 2021

The Price Elasticity Of African Elephant Poaching, Quy-Toan Do, Andrei A. Levchenko, Lin Ma, Julian Blanc, Holly Dublin, Tom Milliken

Research Collection School Of Economics

The objective of this paper is to provide an estimate of the elasticity of elephant poaching with respect to prices. Ivory being a storable commodity subjects its price to Hotelling’s no-arbitrage condition, hence allowing identification of the supply curve. The price of gold, one of many commodities used as stores of value, is thus used as an instrument for ivory prices. The supply of illegal ivory is found to be price inelastic with an elasticity of 0.4, with changes in consumer prices passing-through to prices faced by producers at a rate close to unity. Estimations based on a number of …

Spatial Dynamic Models With Short Panels: Evaluating The Impact Of Home Purchase Restrictions On Housing Prices, Naqun Huang, Zhenlin Yang Oct 2021

Spatial Dynamic Models With Short Panels: Evaluating The Impact Of Home Purchase Restrictions On Housing Prices, Naqun Huang, Zhenlin Yang

Research Collection School Of Economics

Since the 2007 housing crisis in the United States, many countries have begun implementing various macroprudential policies to curb the ongoing rise in housing prices. As there is no clear consensus in the literature on the efficacy of these interventions, understanding their short-term impacts is crucial in informing future policy designs. Adapting a new econometric technique, we examine the short-term impact of home purchase restrictions in Singapore, accounting for the short panel nature of the data and the existence of dynamic, spatial, spatiotemporal, and unit-specific effects. Using quarterly housing data over 2012Q4-2014Q2, we find that public housing prices decrease by …

Decree Power In Parliamentary Systems: Theory And Evidence From India, Madhav Shrihari Aney, Shubhankar Dam Oct 2021

Decree Power In Parliamentary Systems: Theory And Evidence From India, Madhav Shrihari Aney, Shubhankar Dam

Research Collection School Of Economics

Decree powers are common to presidential systems; they are rarely found in parliamentary ones. We analyze decree powers in one such rare setting: India. We show that bicameral minority governments in India systematically use ordinances to circumvent parliament and prosecute their legislative agendas. They promulgate more ordinances, enact less legislation, and often repromulgate lapsed ordinances. These patterns suggest that, with bicameral minority governments, the locus of lawmaking shifts to the executive branch. While both majority and minority governments invoke ordinances, the latter do so systematically to get around their parliamentary deficit. In the hands of minority governments, then, the mechanism …
