School Committee Composition: Exploring The Role Of Parental And Female Representation In India, Panchali Guha

Research Collection Lee Kong Chian School Of Business

Motivation: The adoption of school-based management (SBM) reforms has led to the formation of local-level school committees in many low- and middle-income countries. These committees are usually created with the stated aim of giving parents or local community members a greater say in school management. Various studies have, however, highlighted difficulties with parental and female participation, casting doubt on the extent to which greater community representation improves school management. Purpose: The article examines empirically whether greater parental and female representation in Indian school management committees (SMCs) is associated with school improvement as measured by increases in the school-level provision of …

The rapidly expanding scope of shared transportation services now includes ride-sourcing, ridesharing, car sharing, hitch service, flexible paratransit, shared freight delivery, shared logistics, bike sharing, shared last-mile service, parking space sharing, and so on.

Resale Hdb Price Prediction Considering Covid-19 Through Sentiment Analysis, Srinaath Anbu Durai, Zhaoxia Wang

Research Collection School Of Computing and Information Systems

Twitter sentiment has been used as a predictor to predict price values or trends in both the stock market and housing market. The pioneering works in this stream of research drew upon works in behavioural economics to show that sentiment or emotions impact economic decisions. Latest works in this stream focus on the algorithm used as opposed to the data used. A literature review of works in this stream through the lens of data used shows that there is a paucity of work that considers the impact of sentiments caused due to an external factor on either the stock or …

Learning-Based Stock Trending Prediction By Incorporating Technical Indicators And Social Media Sentiment, Zhaoxia Wang, Zhenda Hu, Fang Li, Seng-Beng Ho, Erik Cambria

Research Collection School Of Computing and Information Systems

Stock trending prediction is a challenging task due to its dynamic and nonlinear characteristics. With the development of social platform and artificial intelligence (AI), incorporating timely news and social media information into stock trending models becomes possible. However, most of the existing works focus on classification or regression problems when predicting stock market trending without fully considering the effects of different influence factors in different phases. To address this gap, this research solves stock trending prediction problem utilizing both technical indicators and sentiments of the social media text as influence factors in different situations. A 3-phase hybrid model is proposed …

The second part of this chapter presents a case study and …

Title Matters: Impacts Of Titles On User Engagement In Short Video Platforms, Hao Chen

Dissertations and Theses Collection (Open Access)

With the increasing popularity of short video marketing in business world, understanding how to engage short video viewers has attracted the attention from both academics and practitioners. Prior studies on short videos mainly focus on how characteristics of users or the attributes of video content affect marketing effectiveness. As a heuristic cue of short video content, the video title is expected to grab viewers’ attention thereby playing an important role in influencing viewers’ attitudes towards the short video consumption. Drawing on signaling theory, I propose that the characteristics of short video titles, such as the length, the sentiment strength, and …

Using survey data from 119 CEOs in China, this dissertation tests the theoretical hypotheses and offers several implications for …

A Hybrid Active Learning Framework For Personal Thermal Comfort Models, Duygu Zeynep Tekler, Yue Lei, Yuzhen Peng, Clayton Miller, Adrian Chong

Research Collection College of Integrative Studies

Personal thermal comfort models are used to predict individual-level thermal comfort responses to inform design and control decisions of buildings to achieve optimal conditioning for improved comfort and energy efficiency. However, the development of data-driven thermal comfort models requires collecting a large amount of sensor-related measurements and user-labelled data (i.e., user feedback) to achieve accurate predictions, which can be highly intrusive and labour intensive in real-world applications. In this work, we propose a hybrid active learning framework to reduce data collection costs for developing data-efficient and robust personal comfort models that predict users’ thermal comfort and air movement preferences. Through …

Continuous Implementation With Payoff Knowledge, Yi-Chun Chen, Takashi Kunimoto, Yifei Sun

Research Collection School Of Economics

The literature on robust mechanism design assumes players' knowledge about a fixed payoff environment and investigates global robustness of optimal mechanisms to large changes in the information structure. Acknowledging global robustness as a demanding requirement, we propose continuous implementation as a notion of local robustness. Keeping the assumption of payoff knowledge, we say that an SCF is continuously implementable if there exists a mechanism which yields the outcome close to the desired one for all types close to the planner's initial model. We show that when a generic correlation condition is imposed on the class of interdependent-value environments, any (interim) …

Local Dominance, Emiliano Catonini, Jingyi Xue

Research Collection School Of Economics

We define notions of dominance between two actions in a dynamic game. Local dominance considers players who have a blurred view of the future and compare the two actions by first focusing on the outcomes that may realize at the current stage. When considering the possibility that the game may continue, they can only check that the local comparison is not overturned under the assumption of "continuing in the same way" after the two actions (in a newly defined sense). Despite the lack of forward planning, local dominance solves dynamic mechanisms that were found easy to play and implements social …

Maximising Effectiveness Of Talent Pools Through Mindfulness: An Empirical Investigation In A Multinational Corporation, Tarmo Raudsepp

Traditional human resource management is looking to identify and develop talent for maximising human capital in a competitive environment with limited resources and negative demographic trends. Attracting, deploying, motivating, developing and retaining talented employees is a corporate norm for meeting organisational goals. Proper human resource processes through rigorous mapping of employees according to the performance-potential matrix allow the grading of employees against peer groups to establish talent pools for development and internal succession planning.

Mindfulness originates from 2,500-year-old Buddhist spiritual practices and has a rare combination of spirituality and science. Eastern perspective originates from Asian traditions focusing on the self-regulation …

The Impact Of Subordinates’ Proactive Personality On Empowering Leadership, Xin Zhan

Dissertations and Theses Collection (Open Access)

Research has documented numerous benefits of proactive personality for employees’ job outcomes. However, the success of proactive employees largely depends on their leaders’ empowerment. Extant research has focused on the bright side of proactive personality for inducing empowerment, without considering its risks. We thus have an incomplete understanding of the effects of employees’ proactive personality on empowering leadership. I take a balanced perspective on proactive personality and propose that proactive personality has an inverted U-shaped relationship with empowering leadership, such that empowering leadership is highest when proactive personality is at a moderate level. I argue that leader-member exchange (LMX) mediates …

Asymptotic Properties Of Least Squares Estimator In Local To Unity Processes With Fractional Gaussian Noises, Xiaohu Wang, Weilin Xiao, Jun Yu

Research Collection School Of Economics

This paper derives asymptotic properties of the least squares estimator of the autoregressive parameter in local to unity processes with errors being fractional Gaussian noises with the Hurst parameter H 2 (0; 1). It is shown that the estimator is consistent for all values of H 2 (0; 1). Moreover, the rate of convergence is n 1 when H 2 [0:5; 1). The rate of convergence is n 2H when H 2 (0; 0:5). Furthermore, the limiting distribution of the centered least squares estimator depends on H. When H = 0:5, the limiting distribution is the same as that obtained …

Economic Forecasting In Singapore: The Covid-19 Experience, Hwee Kwan Chow-Tan, Keen Meng Choy

Research Collection School Of Economics

This Special Feature considers how accurately professional forecasters have predicted GDP growth and inflation in Singapore, especially during rare events such as the Global Financial Crisis (GFC) and COVID-19. It also illustrates the value of forecast probability distributions in inferring forecasters’ uncertainty when making predictions, and the degree of consensus between projections from different forecasters. The authors find that one-year ahead forecast errors for GDP growth and inflation increased during the GFC and the COVID-19 pandemic. While professional forecasters did not appear to have followed the Government’s forecasts when predicting growth during the GFC, they may have exhibited ”leader-following” behaviour …

Estimation And Inference With Near Unit Roots, Peter C. B. Phillips

Research Collection School Of Economics

New methods are developed for identifying, estimating, and performing inference with nonstationary time series that have autoregressive roots near unity. The approach subsumes unit-root (UR), local unit-root (LUR), mildly integrated (MI), and mildly explosive (ME) specifications in the new model formulation. It is shown how a new parameterization involving a localizing rate sequence that characterizes departures from unity can be consistently estimated in all cases. Simple pivotal limit distributions that enable valid inference about the form and degree of nonstationarity apply for MI and ME specifications and new limit theory holds in UR and LUR cases. Normalizing and variance stabilizing …

A Review And Reflection On Open Datasets Of City-Level Building Energy Use And Their Applications, Xiaoyu Jin, Chong Zhang, Fu Xiao, Ao Li, Clayton Miller

Research Collection College of Integrative Studies

Data related to building energy use fuels the research and applications on building energy efficiency, which is an essential measure to address global energy and environmental challenges. However, in most cities, there is a lack of comprehensive and publicly accessible building energy use datasets with necessary temporal and spatial granularities to support urban building energy modeling, regional energy planning, city-level building performance benchmarking, and policymaking on building energy efficiency. Data owners and governments are facing challenges in determining which and how building energy use data should be disclosed at the city level and how to protect data privacy. This review …

Kiasu (Fear Of Losing Out): An Indigenous Psychological Construct In Singapore And Its Impact, Chi-Ying Cheng, Sheila X. R. Wee

Research Collection School of Social Sciences

“Kiasu,” a Hokkien term, which directly translates as the “fear of losing out” is synonymous with the Singapore identity. Yet, there has been little empirical research investigating this indigenous psychological construct in Singapore. This paper first delves into Singapore’s Kiasu culture and existing research of Kiasu, which diverges on the operationalization and measurement of Kiasu as a psychological construct. While early research conceptualized Kiasu as a behavioral tendency, more recent investigations have begun to construe Kiasu as a mindset. Next, we review Kiasu-related outcomes in four domains: academic performance, learning strategies, well-being, and creativity. Finally, we propose a new theoretical …

Adjustment With Many Regressors Under Covariate-Adaptive Randomizations, Liang Jiang, Liyao Li, Ke Miao, Yichong Zhang

Research Collection School Of Economics

Our paper identifies a trade-off when using regression adjustments (RAs) in causal inference under covariate-adaptive randomizations (CARs). On one hand, RAs can improve the efficiency of causal estimators by incorporating information from covariates that are not used in the randomization. On the other hand, RAs can degrade estimation efficiency due to their estimation errors, which are not asymptotically negligible when the number of regressors is of the same order as the sample size. Failure to account for the cost of RAs can result in over-rejection of causal inference under the null hypothesis. To address this issue, we develop a unified …

Migration And Spatial Misallocation In China, Xiaolu Li, Lin Ma, Yang Tang

Research Collection School Of Economics

We structurally estimate the firm-level frictions across prefectures in China and quantify their aggregate and distributional implications. Based on a general equi-librium model with input and output distortions and migration, we show that the firm-level frictions are less dispersed and less correlated with productivity in richer prefectures. Counterfactual exercises show that reducing the within-prefecture mis-allocation increases the aggregate welfare, discourages migration towards large cities, and narrows the spatial inequality. Moreover, internal migration alleviates the impacts of micro-frictions on aggregate welfare and worsens their impacts on spatial inequality.

The Importance Of Considering Debt And Young Children In Activation: A Survival Analysis Of Return To Welfare, Irene N. Y. Ng, Jian Qi Tan, Mathews Mathew, Kong Weng Ho, Yi Ting Ting

Research Collection School Of Economics

While there has been much research on welfare exit and entry into employment, less research has looked at return to government assistance. Applying survival analysis on data from a national government assistance programme in Singapore, we found two important factors of welfare return to which activation programmes need to pay greater attention. First, return was more likely if former beneficiaries accumulated a higher number of types of arrears rather than higher dollar values of arrears. This new finding contributes to the emerging literature on bandwidth tax, and suggests the importance of designing programmes that relieve mental accounting due to debt …

'99-To-1’ Property Deals: Stamp Duty Avoidance Or Honest Mistake, Vincent Ooi

Research Collection Yong Pung How School Of Law

This article explains in detail the legal issues surrounding the recent ABSD audit and how exactly the general anti-avoidance rule and the stamp duty avoidance surcharge in the Stamp Duties Act 1929 can be invoked by the IRAS.The article highlights the fact that it may not be enough for a property buyer to show that the '99-to-1' holding was intended to enable the buyer to qualify for a home loan and not 'for stamp duty avoidance'. The property buyer must be able to answer the additional question of why the transfer of the property is 'staggered' in two stages and …

Disgust Sensitivity Relates To Attitudes Toward Gay Men And Lesbian Women Across 31 Nations, F. Van Leeuwen, Y. Inbar, M. B. Petersen, L. Aaroe, P. Barclay, F. K. Barlow, M. De Barra, D. V. Becker, L. Borovoi, J. Choi, N. S. Consedine, J. R. Conway, P. Conway, V. C. Adoric, Li, Norman P.

Research Collection School of Social Sciences

Previous work has reported a relation between pathogen-avoidance motivations and prejudice toward various social groups, including gay men and lesbian women. It is currently unknown whether this association is present across cultures, or specific to North America. Analyses of survey data from adult heterosexuals (N = 11,200) from 31 countries showed a small relation between pathogen disgust sensitivity (an individual-difference measure of pathogen-avoidance motivations) and measures of antigay attitudes. Analyses also showed that pathogen disgust sensitivity relates not only to antipathy toward gay men and lesbians, but also to negativity toward other groups, in particular those associated with violations of …

The Long And Short Of Mistress Relationships: Sex-Differentiated Mate Preferences Reflect A Compromise Of Mating Ideals, Bryan K. C. Choy, Norman P. Li, Kenneth Tan

Research Collection School of Social Sciences

Objective: Evolved mate preferences have taken center stage in evolutionary psychology research, yet this literature has been fairly muted on mate preferences for extrapair partners. Here, we examined the mate preferences for mistress relationships (the traits that men prioritize in a mistress and mistresses prioritize in their male partners) and compared these preferences to those of short- and long-term relationships. Method: In two studies (NStudy 1a = 104, NStudy 1b = 191), we derived dimensions of mate preferences through exploratory factor analyses. In subsequent studies (NStudy 2 = 219, NStudy 3 = 101), we employed a budget allocation paradigm, where …

Can Conflict Cultivate Collaboration? The Positive Impact Of Mild Versus Intense Task Conflict Via Perceived Openness Rather Than Emotions, Ming-Hong Tsai

Research Collection School of Social Sciences

Public Significance Statement In contrast to previous research on the negative associations between conflict and collaboration, the current investigation demonstrates the positive effects of conflict on collaboration and performance and offers practical suggestions on beneficial conflict expressions. Specifically, when people debate and deliberate about their different viewpoints about task-related issues, they tend to collaborate and thus achieve high task performance by enhancing their perceptions of others' openness rather than by influencing their emotions.Previous research has demonstrated negative associations between task-relevant conflicts and collaboration. To supplement the previous findings and explore the potential benefits of conflicts, we differentiate between two types …
