What's On Job Seekers' Social Media Sites? A Content Analysis And Effects Of Structure On Recruiter Judgments And Predictive Validity, L. Zhang, C. H. Van Iddekinge, J. D. Arnold, P. Roth, Filip Lievens, S. Lanivich, S. Jordan Aug 2020

What's On Job Seekers' Social Media Sites? A Content Analysis And Effects Of Structure On Recruiter Judgments And Predictive Validity, L. Zhang, C. H. Van Iddekinge, J. D. Arnold, P. Roth, Filip Lievens, S. Lanivich, S. Jordan

Research Collection Lee Kong Chian School Of Business

Many organizational representatives review social media (SM) information (e.g., Facebook, Twitter) when recruiting and assessing job applicants. Despite this, very little empirical data exist concerning the SM information available to organizations or whether assessments of such information are a valid predictor of work outcomes. This multi-study investigation examines several critical issues in this emerging area. In Study 1, we conducted a content analysis of job seekers’ Facebook sites (n = 266) and found that these sites often provide demographic variables that U.S. employment laws typically prohibit organizations from using when making personnel decisions (e.g., age, ethnicity, religion), as ...

Power And Negotiation: Review Of Current Evidence And Future Directions, Michael Schaerer, Laurel Teo, Nikhil Madan, Roderick I. Swaab Jun 2020

Power And Negotiation: Review Of Current Evidence And Future Directions, Michael Schaerer, Laurel Teo, Nikhil Madan, Roderick I. Swaab

Research Collection Lee Kong Chian School Of Business

This review synthesizes the impact of power on individual and joint negotiation performance. Although power generally has positive effects on negotiators’ individual performance (value claiming), recent work suggests that more power is not always beneficial. Taking a dyadic perspective, we also find mixed evidence for how power affects joint performance (value creation); some studies show that equal-power dyads create more value than unequal-power dyads, but others find the opposite. We identify the source of power, power distribution, and competitiveness as critical moderators of this relationship. Finally, we suggest that future research should move beyond studying alternatives in dyadic deal-making, identify ...


Deviance Information Criterion For Latent Variable Models And Misspecified Models, Yong Li, Jun Yu, Tao Zeng Jun 2020

Deviance Information Criterion For Latent Variable Models And Misspecified Models, Yong Li, Jun Yu, Tao Zeng

Research Collection School Of Economics

Deviance information criterion (DIC) has been widely used for Bayesian model comparison, especially after Markov chain Monte Carlo (MCMC) is used to estimate candidate models. This paper first studies the problem of using DIC to compare latent variable models when DIC is calculated from the conditional likelihood. In particular, it is shown that the conditional likelihood approach undermines theoretical underpinnings of DIC. A new version of DIC, namely DICL, is proposed to compare latent variable models. The large sample properties of DICL are studied. A frequentist justification of DICL is provided. Like AIC, DICL provides an asymptotically unbiased estimator to ...


Identifying Latent Grouped Patterns In Cointegrated Panels, Wenxin Huang, Sainan Jin, Liangjun Su Jun 2020

Identifying Latent Grouped Patterns In Cointegrated Panels, Wenxin Huang, Sainan Jin, Liangjun Su

Research Collection School Of Economics

We consider a panel cointegration model with latent group structures that allows for heterogeneous long-run relationships across groups. We extend Su, Shi, and Phillips (2016, Econometrica 84(6), 2215-2264) classifier-Lasso (C-Lasso) method to the nonstationary panels and allow for the presence of endogeneity in both the stationary and nonstationary regressors in the model. In addition, we allow the dimension of the stationary regressors to diverge with the sample size. We show that we can identify the individuals' group membership and estimate the group-specific long-run cointegrated relationships simultaneously. We demonstrate the desirable property of uniform classification consistency and the oracle properties ...


Depletion Manipulations Decrease Openness To Dissent Via Increased Anger, Ming-Hong Tsai, Norman P. Li May 2020

Depletion Manipulations Decrease Openness To Dissent Via Increased Anger, Ming-Hong Tsai, Norman P. Li

Research Collection School of Social Sciences

We investigated a potential outcome of ego depletion manipulations and an importantfactor behind cooperative failure: a lack of openness to others’ dissenting opinions.Across five studies in a variety of task settings, we examined the effect of depletionmanipulations on openness to dissent and investigated two negative emotions as potentialmediators of this process: fatigue and anger. The results demonstrated a negative effect ofdepletion manipulations on openness to dissent through increased anger rather thanfatigue (Studies 1–5). In Studies 3 and 4, we also eliminated perceived trust towards a taskcounterpart as a significant mediator of the relationship between depletion manipulationsand openness to ...

Early Detection Of Mild Cognitive Impairment With In-Home Sensors To Monitor Behavior Patterns In Community-Dwelling Senior Citizens In Singapore: Cross-Sectional Feasibility Study, Iris Rawtaer, Rathi Mahendran, Ee Heok Kua, Hwee-Pink Tan, Hwee Xian Tan, Tih-Shih Lee, Tze Pin Ng

Research Collection School Of Information Systems

Background: Dementia is a global epidemic and incurs substantial burden on the affected families and the health care system. 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 ...


Corona Crisis And Inequality: Why Management Research Needs A Societal Turn, Hari Bapuji, Charmi Patel, Gokhan Ertug, David G. Allen May 2020

Corona Crisis And Inequality: Why Management Research Needs A Societal Turn, Hari Bapuji, Charmi Patel, Gokhan Ertug, David G. Allen

Research Collection Lee Kong Chian School Of Business

As the world struggles to deal with the COVID-19 pandemic, the stark inequalities in our societies have been laid bare, and the interplay between organizations and societies has also become evident yet again. This crisis underscores the need for management scholars to take a societal turn and examine how organizational practices interact with societal economic inequality. To illustrate this approach, we discuss organizational practices – corporate social responsibility, work design, recruitment and selection, and compensation management – that can contribute to the normalization, reinforcement, and reduction of economic inequalities in society. We conclude by calling on scholars of inequality, as well as ...


Identifying Latent Group Structures In Nonlinear Panels, Wuyi Wang, Liangjun Su May 2020

Identifying Latent Group Structures In Nonlinear Panels, Wuyi Wang, Liangjun Su

Research Collection School Of Economics

We propose a procedure to identify latent group structures in nonlinear panel data models where some regression coefficients are heterogeneous across groups but homogeneous within a group and the group number and membership are unknown. To identify the group structures, we consider the order statistics for the preliminary unconstrained consistent estimators of the regression coefficients and translate the problem of classification into the problem of break detection. Then we extend the sequential binary segmentation algorithm of Bai (1997) for break detection from the time series setup to the panel data framework. We demonstrate that our method is able to identify ...


Detecting Latent Communities In Network Formation Models, Shujie Ma, Liangjun Su, Yichong Zhang May 2020

Detecting Latent Communities In Network Formation Models, Shujie Ma, Liangjun Su, Yichong Zhang

Research Collection School Of Economics

This paper proposes a logistic undirected network formation model which allows for assortative matching on observed individual characteristics and the presence of edge-wise fixed effects. We model the coefficients of observed characteristics to have a latent community structure and the edge-wise fixed effects to be of low rank. We propose a multi-step estimation procedure involving nuclear norm regularization, sample splitting, iterative logistic regression and spectral clustering to detect the latent communities. We show that the latent communities can be exactly recovered when the expected degree of the network is of order log n or higher, where n is the number ...


Efficient Bilateral Trade With Interdependent Values: The Use Of Two-Stage Mechanisms, Takashi Kunimoto, Cuiling Zhang May 2020

Efficient Bilateral Trade With Interdependent Values: The Use Of Two-Stage Mechanisms, Takashi Kunimoto, Cuiling Zhang

Research Collection School Of Economics

As efficient, voluntary bilateral trades are generally not incentive compatible in an interdependent-value environment (Fieseler, Kittsteiner, Moldovanu (2003) and Gresik (1991)), we seek for more positive results by employing two-stage mechanisms (Mezzetti (2004)). We say that a two-stage mechanism satisfies incentive compatibility if the truth-telling in both stages constitutes an equilibrium strategy.First, we show by means of a stylized example that the generalized two-stage Groves mechanism never guarantees voluntary trade, while it satisfies efficiency and incentive compatibility. In a general environment, we next propose Assumption 1 under which there exists a two-stage incentive compatible mechanism implementing an efficient, voluntary ...


Forecast Combinations In Machine Learning, Yue Qiu, Tian Xie, Jun Yu May 2020

Forecast Combinations In Machine Learning, Yue Qiu, Tian Xie, Jun Yu

Research Collection School Of Economics

This paper introduces novel methods to combine forecasts made by machine learning techniques. Machine learning methods have found many successful applications in predicting the response variable. However, they ignore model uncertainty when the relationship between the response variable and the predictors is nonlinear. To further improve the forecasting performance, we propose a general framework to combine multiple forecasts from machine learning techniques. Simulation studies show that the proposed machine-learning-based forecast combinations work well. In empirical applications to forecast key macroeconomic and financial variables, we find that the proposed methods can produce more accurate forecasts than individual machine learning techniques and ...


How A Young University Can Launch And Grow A Digital Repository, And Why It Should, Singapore Management University, Pin Pin Yeo May 2020

How A Young University Can Launch And Grow A Digital Repository, And Why It Should, Singapore Management University, Pin Pin Yeo

Research Collection Library

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.


Asymptotic Theory For Near Integrated Processes Driven By Tempered Linear Processes, Farzad Sabzikar, Qiying Wang, Peter C. B. Phillips May 2020

Asymptotic Theory For Near Integrated Processes Driven By Tempered Linear Processes, Farzad Sabzikar, Qiying Wang, Peter C. B. Phillips

Research Collection School Of Economics

In an early article on near-unit root autoregression, Ahtola and Tiao (1984) studied the behavior of the score function in a stationary first order autoregression driven by independent Gaussian innovations as the autoregressive coefficient approached unity from below. The present paper develops asymptotic theory for near-integrated random processes and associated regressions including the score function in more general settings where the errors are tempered linear processes. Tempered processes are stationary time series that have a semi-long memory property in the sense that the autocovariogram of the process resembles that of a long memory model for moderate lags but eventually diminishes ...


Bootstrap Inference For Quantile Treatment Effects In Randomized Experiments With Matched Pairs, Liang Jiang, Xiaobin Liu, Yichong Zhang May 2020

Bootstrap Inference For Quantile Treatment Effects In Randomized Experiments With Matched Pairs, Liang Jiang, Xiaobin Liu, Yichong Zhang

Research Collection School Of Economics

This paper examines inference for quantile treatment effects (QTEs) in randomized experiments with matched-pairs designs (MPDs). We derive the limiting distribution of the QTE estimator under MPDs and highlight the difficulty of analytical inference due to parameter tuning. We show that a naive weighted bootstrap fails to approximate the limiting distribution of the QTE estimator under MPDs because it ignores the dependence structure within the matched pairs. We then propose two bootstrap methods that can consistently approximate that limiting distribution: the gradient bootstrap and the weighted bootstrap of the inverse propensity score weighted (IPW) estimator. The gradient bootstrap is free ...

Free Bodies, Segmented Selves: Paradoxical Spaces Of Dancehall Culture In Singapore, Orlando Woods Apr 2020

Free Bodies, Segmented Selves: Paradoxical Spaces Of Dancehall Culture In Singapore, Orlando Woods

Research Collection School of Social Sciences

This paper contributes to the ongoing expansion of the geographies of encounter by considering how cultural encounters can lead to the realisation, and the segmentation, of the self. As much as cultural differences can be manifested, negotiated and managed externally, so too can these differences be internal states that are realised through engagements with the embodied self. Accordingly, segmented selves are an outcome of the desire for individuals to compartmentalise diverse and disaggregated lives, and to retain a sense of cohesion and harmony within the various socio-cultural communities to which they belong. I bring these ideas to life through an ...


Foreign Direct Investment And Industrial Agglomeration: Evidence From China, Wen-Tai Hsu, Yi Lu, Xuan Luo, Lianming Zhu Apr 2020

Foreign Direct Investment And Industrial Agglomeration: Evidence From China, Wen-Tai Hsu, Yi Lu, Xuan Luo, Lianming Zhu

Research Collection School Of Economics

This paper studies the effect of foreign direct investment (FDI) on industrial ag-glomeration. Using the differential effects of FDI deregulation in 2002 in China on different industries, we find that FDI actually affects industrial agglomeration neg-atively. As FDI brings technological spillovers and various agglomeration benefits, other forces must be at work to drive our empirical finding. We propose a simple theory that FDI may discourage industrial agglomeration due to fiercer competition pressure. We find various evidence on this competition mechanism. We also examine an alternative theory based on spatial political competition, but find no evidence sup-porting it. On industrial growth ...

Heterosexual intercourse serves the evolutionarily adaptive function of reproduction and gene propagation. However, engaging in sexual intercourse also entails risks in contracting Sexually Transmitted Infections (STIs) that bring about pain and health complications. While STIs typically do not pose a direct threat to one's life, the Human Immunodeficiency Virus (HIV), a relatively recent emergent STI, does. Also, unlike other existing STIs such as Gonorrhea, people infected with HIV typically do not display obvious symptoms that would prompt preventive actions from their sexual partners. Accordingly, consistent condom usage (or lack thereof) has become one of the top concerns of HIV ...


Does Diversity In Team Members’ Agreeableness Benefit Creative Teams?, Sean Teck Hao Lee, Guihyun Park Apr 2020

Does Diversity In Team Members’ Agreeableness Benefit Creative Teams?, Sean Teck Hao Lee, Guihyun Park

Research Collection School of Social Sciences

Although deep-level diversity among team members are often discussed as important catalysts of team creativity, little is currently understood about the impact of diversity in team members’ personality on team creativity and team satisfaction. We propose that diversity in team members’ agreeableness would reduce the effectiveness of creative teams through its impact on team conflict experienced. To test our hypotheses, we recruited 93 student teams to participate in a laboratory study where each member had their personality traits assessed before engaging in a team creativity task. We found that diversity in team members’ agreeableness was positively associated with team task ...

Social Media Use Improves Executive Functions In Middle-Aged And Older Adults: A Structural Equation Modeling Analysis, Shi Ann Shuna Khoo, Hwajin Yang

Research Collection School of Social Sciences

Given the paucity of research on the cognitive implications of social media use in middle and late adulthood, we sought to understand the relations between middle-aged and older adults' social media use and their executive functions (EF)—a set of domain-general cognitive control processes—and the underlying mechanism. By analyzing a nationally representative cohort ranging from ages 40s–70s from the MIDUS Refresher Survey and Cognitive Project, we tested a serial mediation model with perception of social support and sense of control (i.e., personal mastery and perceived constraints) as sequential mediators in a structural equation modeling analysis. We found ...

Parallel Spaces Of Migrant (Non-)Integration In Singapore: Latent Politics Of Distance And Difference Within A Diverse Christian Community, Orlando Woods, Lily Kong Apr 2020

Parallel Spaces Of Migrant (Non-)Integration In Singapore: Latent Politics Of Distance And Difference Within A Diverse Christian Community, Orlando Woods, Lily Kong

Research Collection School of Social Sciences

This paper explores how the spatial practices of churches can lead to the (non-)integration of migrant communities. Whilst churches bring migrants and non-migrants together in space and time, so too can they cause them to become divided along ethnic, national, linguistic and/or class-based lines. In such cases, migrants can become integrated into a community of other migrants, which can discourage integration into the church-at-large, or into society more generally. These practices of (non-)integration give rise to parallel spaces of Christian praxis that can lead to the reproduction of distance and difference between (and within) migrant and non-migrant ...
