Two Roads Diverged: An Alternative Perspective On The Easi Model, Nadhilla Velda Melia

Dissertations and Theses Collection (Open Access)

Research on the interpersonal effect of anger expressions on others’ concessionary behaviour has found conflicting results about whether anger expressions increase or decrease concessionary behaviour. The Emotions as Social Information (EASI) model (Van Kleef, 2009, 2014) proposed that these conflicting findings can be resolved by looking at inferential and affective processes. Specifically, anger expressions increase concessionary behaviour via inferential processes but decrease concessionary behaviour via affective processes. However, previous research has mainly focused on dominance-related inferences and reciprocal anger reactions. I propose that the relationship between anger expressions and concessionary behaviour is determined by the type of inferential and affective …

The Many Faces Of Class Ceiling: Its Manifestations At Different Career Stages And Ways To Overcome It, Jia Hui Lim

Dissertations and Theses Collection (Open Access)

Even with comparable education and level of competence, workers with lower socioeconomic status (SES) origins are disadvantaged in terms of earnings and occupational attainment. This class gap, or the “class ceiling,” is as large as the gender gap, but poorly understood. In my dissertation, I designed a series of related projects to explain and potentially mitigate the class ceiling problem. Across three projects, I mainly focused on where the problem starts—labor market and newcomer adjustment in organizations. I find that, beyond discrimination and bias that has been the focus of past work, many challenges stem from workers’ own psychology and …

Three Essays On Nonstationary Financial Econometrics, Yajie Zhang

Dissertations and Theses Collection (Open Access)

This dissertation consists of three essays that contribute to the theory of nonstationary time-series analysis.

The first chapter explores the inference procedures for predictive regressions with time-varying characteristics. We extend the self-generated instrumentation, called IVX, to incorporate persistent regressors of functional local-to-unity, functional mildly explosive, and functional mildly stationary roots. The asymptotic distributions of IVX estimators under time-varying parameters are novel and nonpivotal but lead to pivotal distributions of the corresponding Wald statistics that are robust across various roots. The numerical experiments justify the robustness of IVX testing procedures in finite samples. We also verify the existence of time-varying coefficients …

Pressure To Be Creative: How Employees Respond To Organizational Creativity Pressure, Hye Jung Eun

Dissertations and Theses Collection (Open Access)

Creativity and innovation are vital for organizational growth and success, driving many organizations to increase pressure for employee creativity. Yet, researchers have neglected investigating how employees respond to creativity pressure at the workplace. This dissertation introduces and develops a new scale for the concept of organizational creativity pressure – the pressure on employees to continually develop novel and useful ideas and solutions. The scale is further validated through extensive assessment of content and construct validity, empirically differentiating the construct from similar others such as performance pressure and support for creativity.

Drawing on the transactional theory of stress (Lazarus & Folkman, …

Two Essays On Innovation And Growth In China, Qiugu He

Dissertations and Theses Collection (Open Access)

This dissertation studies China’s economic growth from a perspective of industry dynamics. In chapter 1, I introduce the background and policies relating to China’s economic growth after 1978. In chapter 2, I find that the elasticity of the average R&D expenditure of firms on competition is -0.29 in weak-IPR (intellectual property right) provinces, and -0.06 in strict-IPR provinces. Next, I use the Schumpeterian growth model to explain this finding: When the market becomes more competitive, a firm prefers imitation to innovation to a larger extent, as a means of getting new technology. Due to enforcement of IPR laws, the imitation …

The Impact Of Kiasu Mindset On Students’ Achievement Goal Orientations And Learning Strategies In Singapore, Haelim Choi

Dissertations and Theses Collection (Open Access)

Kiasuism, defined as the fear of losing out, has been a well-known and widespread phenomenon in Singapore. Despite the long history of Kiasuism in Singaporeans, there has been a dearth of research in this topic. The current research investigated the influence of the Kiasu mindset on Singaporean students’ achievement goal orientation and learning strategy, and also explored the impact of social comparison as a moderator. Study 1 showed initial evidence of a positive relationship between Kiasu mindset and performance goal orientations (i.e., approach and avoidance). Study 2 replicated this finding and further revealed a positive association of Kiasu mindset with …

More Kawaii Than A Real-Person Live Streamer: Understanding How The Otaku Community Engages With And Perceives Virtual Youtubers, Zhicong Lu, Chenxinran Shen, Jiannan Li, Hong Shen, Daniel Wigdor

Research Collection School Of Computing and Information Systems

Live streaming has become increasingly popular, with most streamers presenting their real-life appearance. However, Virtual YouTubers (VTubers), virtual 2D or 3D avatars that are voiced by humans, are emerging as live streamers and attracting a growing viewership in East Asia. Although prior research has found that many viewers seek real-life interpersonal interactions with real-person streamers, it is currently unknown what makes VTuber live streams engaging or how they are perceived differently than real-person streamers. We conducted an interview study to understand how viewers engage with VTubers and perceive the identities of the voice actors behind the avatars (i.e., Nakanohito). The …

Politically Directed Accumulation In Rural China: The Making Of The Agrarian Capitalist Class And The New Agrarian Question Of Capital, Qian Forrest Zhang, Hongping Zeng

Research Collection School of Social Sciences

We study the formation of the agrarian capitalist class in the pig farming sector in a Chinese county. We propose a new framework for analyzing the dynamics of accumulation and class formation in agriculture that focuses on the role of the state and public resources. In what we call “politically directed accumulation,” local states in China, driven by a political logic of maximizing fiscal resources and improving performance record, select actors who either have accumulated non-agrarian capital or possess political capital to serve as their agents (political selection) and then capitalize their farming operations by transferring to them public resources …

Foreign Judgments: The Limits Of Transnational Issue Estoppel, Reciprocity, And Transnational Comity, Tiong Min Yeo

Research Collection Yong Pung How School Of Law

In Merck Sharp & Dohme Corp v Merck KGaA [2021] SGCA 14, a full bench of the Singapore Court of Appeal addressed the limits of transnational issue estoppel in Singapore law, and flagged possible fundamental changes to the common law on the recognition and enforcement of foreign judgments in Singapore. The litigation involves multiple parties spread over different jurisdictions. The specific facts involved in the appeal are fairly straightforward, centring on what has been decided in a judgment from the English court, and whether it could be used to raise issue estoppel on the interpretation of a particular term of …

Fake News, Epistemic Coverage And Trust, Shane Ryan

Research Collection School of Social Sciences

This article makes the case that a deficit or absence of trust in media sources to report on newsworthy items facilitates acceptance of fake news. The article begins by identifying the sort of fake news that is of interest for the purposes of this article. Epistemic coverage is then explained-in particular, how an individual's expectations about their epistemic environment can lead them to accepting or rejecting claims. The article explains that when an individual believes that mainstream media report on what is deemed newsworthy, it follows that an individual will have grounds to dismiss a newsworthy claim that has not …

Effects Of Bin Proximity And Informational Prompts On Recycling And Contamination, Sonny Rosenthal, Noah Linder

Research Collection College of Integrative Studies

This between-subjects experiment manipulated the proximity of a waste bin relative to a recycling bin and the presence of information about why and how to rinse recyclables. After completing a yogurt taste test, 272 undergraduate students disposed of their plastic tasting cups in either a waste bin or a recycling bin. Binary logistic regression showed use of the recycling bin roughly tripled when the waste bin was made less convenient by moving it away from the tasting area (p R2 = 0.54). Univariate ANOVA showed the contamination level of recycled items was lower when an informational prompt indicated how clean …

Good Deeds Done In Silence: Stakeholder Management And Quiet Giving By Chinese Firms, Heli Wang, Ming Jia, Zhe Zhang

Research Collection Lee Kong Chian School Of Business

We propose a new mechanism explaining why companies may remain silent about their positive corporate behaviors, such as socially responsible activities. We examine such strategic silence in the context of corporate philanthropy. Building on and extending the literature on legitimacy and stakeholder management, we argue that when a firm mistreats primary stakeholders, it is more likely to keep quiet about its philanthropic acts to avoid backlash from stakeholders. We also propose that long-term orientation among stakeholders mitigates the positive relationship between mistreating primary stakeholders and quiet giving, which allows stakeholders to appreciate the long-term value of corporate philanthropy. Data from …

Adaptive Operating Hours For Improved Performance Of Taxi Fleets, Rajiv Ranjan Kumar, Pradeep Varakantham, Shih-Fen Cheng

Research Collection School Of Computing and Information Systems

Taxi fleets and car aggregation systems are an important component of the urban public transportation system. Taxis and cars in taxi fleets and car aggregation systems (e.g., Uber) are dependent on a large number of self-controlled and profit-driven taxi drivers, which introduces inefficiencies in the system. There are two ways in which taxi fleet performance can be optimized: (i) Operational decision making: improve assignment of taxis/cars to customers, while accounting for future demand; (ii) strategic decision making: optimize operating hours of (taxi and car) drivers. Existing research has primarily focused on the operational decisions in (i) and we focus on …

Angrybert: Joint Learning Target And Emotion For Hate Speech Detection, Md Rabiul Awal, Rui Cao, Roy Ka-Wei Lee, Sandra Mitrović

Research Collection School Of Computing and Information Systems

Automated hate speech detection in social media is a challenging task that has recently gained significant traction in the data mining and Natural Language Processing community. However, most of the existing methods adopt a supervised approach that depended heavily on the annotated hate speech datasets, which are imbalanced and often lack training samples for hateful content. This paper addresses the research gaps by proposing a novel multitask learning-based model, AngryBERT, which jointly learns hate speech detection with sentiment classification and target identification as secondary relevant tasks. We conduct extensive experiments to augment three commonly-used hate speech detection datasets. Our experiment …

Measuring Law Over Time: A Network Analytical Framework With An Application To Statutes And Regulations In The United States And Germany, Corinna Coupette, Janis Beckedorf, Dirk Hartung, Michael Bommarito, Daniel Martin Katz

Research Collection Yong Pung How School Of Law

How do complex social systems evolve in the modern world? This question lies at the heart of social physics, and network analysis has proven critical in providing answers to it. In recent years, network analysis has also been used to gain a quantitative understanding of law as a complex adaptive system, but most research has focused on legal documents of a single type, and there exists no unified framework for quantitative legal document analysis using network analytical tools. Against this background, we present a comprehensive framework for analyzing legal documents as multi-dimensional, dynamic document networks. We demonstrate the utility of …

The Response Of The Chinese Economy To The U.S.-China Trade War: 2018-2019, Pao-Li Chang, Kefang Yao, Fan Zheng

Research Collection School Of Economics

In this paper, we follow the micro-to-macro approach of Fajgelbaum et al. (2020) and analyze the impacts of the 2018–2019 U.S.-China trade war on the Chinese economy. We use highly disaggregated trade and tariff data with monthly frequency to identify the demand/supply elasticities of Chinese imports/exports, combined with a general equilibrium model for the Chinese economy (that takes into account input-output linkages, and regional heterogeneity in employment and sector specialization) to quantify the partial and general equilibrium effects of the tariff war at the product/sector/region/aggregate levels. This complements the studies that focus on the ex post response of the U.S. …

Business Cycles, Trend Elimination, And The Hp Filter, Peter C. B. Phillips, Sainan Jin

Research Collection School Of Economics

Trend elimination and business cycle estimation are analyzed by finite sample and asymptotic methods. An overview history is provided, operator theory is developed, limit theory as the sample size n → ∞ is derived, and filtered series properties are studied relative to smoothing parameter (λ) behavior. Simulations reveal that limit theory with λ =O(n4) delivers excellent approximations to the HP filter for common sample sizes but fails to remove stochastic trends, contrary to standard thinking in macroeconomics and thereby explaining ‘spurious cycle’ effects of the HP filter. The findings are related to the long run effects of the GFC.

Boosting: Why You Can Use The Hp Filter, Peter C. B. Phillips, Zhentao Shi

Research Collection School Of Economics

We propose a procedure of iterating the HP filter to produce a smarter smoothing device, called the boosted HP (bHP) filter, based on L2-boosting in machine learning. Limit theory shows that the bHP filter asymptotically recovers trend mechanisms that involve integrated processes, deterministic drifts, and structural breaks, covering the most common trends that appear in current modeling methodology. A stopping criterion automates the algorithm, giving a data-determined method for data-rich environments. The methodology is illustrated in simulations and with three real data examples that highlight the differences between simple HP filtering, the bHP filter, and an alternative autoregressive approach.

In-Fill Asymptotic Theory For Structural Break Point In Autoregression, Liang Jiang, Xiaohu Wang, Jun Yu

Research Collection School Of Economics

This article obtains the exact distribution of the maximum likelihood estimator of structural break point in the Ornstein–Uhlenbeck process when a continuous record is available. The exact distribution is asymmetric, trimodal, dependent on the initial condition. These three properties are also found in the finite sample distribution of the least squares (LS) estimator of structural break point in autoregressive (AR) models. Motivated by these observations, the article then develops an in-fill asymptotic theory for the LS estimator of structural break point in the AR(1) coefficient. The in-fill asymptotic distribution is also asymmetric, tri-modal, dependent on the initial condition, and delivers …

Design Thinking As A Means Of Citizen Science For Social Innovation, Hoe Chin Goi, Wee Liang Tan

Research Collection Lee Kong Chian School Of Business

Members of the public or community can play a significant role in the development of social innovations. When a social innovation is developed involving a scientific approach and the community, there is the confluence of two fields-citizen science and social innovation. Social innovations can be developed through the employment of design-thinking. In this paper, we advocate design thinking as an approach to marry the two fields for a desired outcome of improved community life in ageing housing estates in Tokyo. The two fields, citizen science and social innovation, are described in brief before the design thinking method is introduced and …

Developmental Dyslexia And Creativity: A Meta-Analysis, Nadyannam M. Majeed, Andree Hartanto, Jacinth J. X. Tan

Research Collection School of Social Sciences

Despite difficulties in reading and writing, some research suggests that dyslexia may be related to higher levels of creativity. However, this pattern is not consistently observed. The current research sought to ascertain whether individuals with clinically diagnosed dyslexia exhibit higher creativity than controls through a meta-analysis. Fourteen studies that assessed the creativity of 397 individuals with clinically diagnosed dyslexia and 453 controls were reviewed. Random-effects meta-analysis revealed an overall non-significant difference in creativity scores between those with dyslexia and controls. Additionally, method factors such as the type of creativity task and whether intelligence was controlled for, as well as sample-related …

On Factor Models With Random Missing: Em Estimation, Inference, And Cross Validation, Sainan Jin, Ke Miao, Liangjun Su

Research Collection School Of Economics

We consider the estimation and inference in approximate factor models with random missing values. We show that with the low rank structure of the common component, we can estimate the factors and factor loadings consistently with the missing values replaced by zeros. We establish the asymptotic distributions of the resulting estimators and those based on the EM algorithm. We also propose a cross validation-based method to determine the number of factors in factor models with or without missing values and justify its consistency. Simulations demonstrate that our cross validation method is robust to fat tails in the error distribution and …

Lethal, Viral, Global: The Role Of Mobile Media And The Growing International Scourge Of Fake News, Gordon Kuo Siong Tan, Sun Sun Lim, Roy Kheng

Research Collection College of Integrative Studies

The rising ubiquity of mobile-enabled devices has greatly accelerated the spread of online disinformation. Media production and dissemination capabilities are within easy reach of consumers, who may become key nodes in sharing fabricated information. Social media platforms’ advertisement-driven revenue models have encouraged the proliferation of viral and inflammatory content, where journalistic best practices are de-emphasized. Furthermore, opaque algorithms favor fake stories that elicit greater emotional responses from users. Increased deregulation has given mobile media companies considerable freedom over content moderation policies. Finally, emerging mobile technologies have enabled more sophisticated and richer forms of fabricated content to be circulated among a …

Singapore: Value Creating Elites Lead The World, Christine Henderson

Research Collection School of Social Sciences

Singapore country scorecard for the 2021 Elite Quality Index (EQx2021), a global ranking of countries built on the notion of ‘elite quality’. Elite quality is a macro-level feature of the political economy that measures the value creation aggregate of all elite business models. Elites are dominant coalitions with the strongest capacity for coordination in societies and operate the highest impact business models. Elite business models can either create sustainable value or extract value from others, primarily from non-elites (i.e., through rent-seeking). Value creation activities include innovation, trade or production; value extraction includes barriers, discrimination or monopolies. The higher the value …

Tripdecoder: Study Travel Time Attributes And Route Preferences Of Metro Systems From Smart Card Data, Xiancai Tian, Baihua Zheng, Yazhe Wang, Hsao-Ting Huang, Chih-Cheng Hung

Research Collection School Of Computing and Information Systems

In this paper, we target at recovering the exact routes taken by commuters inside a metro system that are not captured by an Automated Fare Collection (AFC) system and hence remain unknown. We strategically propose two inference tasks to handle the recovering, one to infer the travel time of each travel link that contributes to the total duration of any trip inside a metro network and the other to infer the route preferences based on historical trip records and the travel time of each travel link inferred in the previous inference task. As these two inference tasks have interrelationship, most …

Prof. Edward (Ed) Diener (1946-2021), a pioneer in positive psychology, passed away on the 27th of April 2021 at his home in Salt Lake City, Utah (Salt Lake City Tribune, 2021). As one of the most influential psychologists of the discipline, Ed Diener pushed the boundaries of our understanding of positive psychological functioning, subjective well-being, and happiness (Layous, 2020). As one of the Top 200 most cited researchers across all disciplines and fields, he will be most remembered for founding the scientific study of subjective well-being (SWB) and happiness (Bakshi, 2019). Diener developed the concept of subjective well-being by exploring …
