Measuring Differentials In Communication Research: Issues With Multicollinearity In Three Methods, Sonny Rosenthal

Research Collection College of Integrative Studies

Models of communication processes sometimes require the computation of the difference between two variables. For example, information insufficiency is the difference between what people know and what they think they need to know about an issue, and it can motivate information seeking and processing. Common methods that compute this differential may bias model estimates as a function of the correlation between the differentiated variables and other variables in the model. This article describes Citation the general form of Cohen and Cohen's (1983) analysis of partial variance for computing differentials and analyzes simulated data to contrast that method with two alternative …

Living With Voters’ Existential Angst, Tan K. B. Eugene

Research Collection Yong Pung How School Of Law

SMU Assistant Professor of Law and NMP Eugene Tan analysed the results of the Punggol East by-election and discussed what it signals next for the People’s Action Party (PAP), the Workers’ Party, the opposition in general and Singaporeans. He said that while we should be careful not to extrapolate the results of the Punggol East by-election as being a barometer of national sentiment, the results are nonetheless a useful snapshot of the dynamic political situation. He added that PAP urgently needs to connect more with this existential angst, anxiety and aspirations of voters who feel a growing sense of alienation. …

A New Approach To An Old Problem: Defining Nursing’S Role In Successful Transitions To Long-Term Residential Care, Kyleen Aldrich

Honors College Theses

A growing body of nursing research addresses the transitional period for older adults entering long-term residential care. However, gaps exist in our understanding of nursing’s role in the transition process. Our aim is to examine the available evidence and develop a model of nursing strategies and interventions to ease the transition to long-term care. This model describes interventions that nurses can incorporate into everyday practice.

A literature review was conducted to examine the transitional care needs and interventions for older adults with a goal of developing a model addressing transitions to long-term care.

Most nursing studies provided descriptive information about …

Developmental Changes In Postural Stability During The Performance Of A Precision Manual Task, Jeffrey M. Haddad, Laura J. Claxton, Dawn Melzer, Joseph Hamill, Richard E. A. Van Emmerik

Psychology Faculty Publications

Posture becomes integrated with other goal-directed behaviors early in infancy and continues to develop into the second decade of life. However, the developmental time course over which posture is stabilized relative to the base of support during a dynamic manual precision task has not been examined. Postural-manual integration was assessed in 7-year-olds, 10-year-olds, and adults using a postural-manual task in which task precision (target fitting size) and postural difficulty (reaching distance to a target) were manipulated. The main dependent variable was postural time-to-contact (TtC). Results indicated systematic age effects in which TtC was shortest in the 7-year-olds, increased in the …

When Parity Promotes Peace: Resolving Conflict Between Asymmetric Agents, Erik O. Kimbrough, Roman M. Sheremeta, Timothy W. Shields

ESI Working Papers

Due to the high costs of conflict both in theory and practice, we examine and experimentally test the conditions under which conflict between asymmetric agents can be resolved. We model conflict as a two-agent rent-seeking contest for an indivisible prize. Before conflict arises, both agents may agree to allocate the prize by fair coin flip to avoid the costs of conflict. The model predicts that “parity promotes peace”: in the pure-strategy equilibrium, agents with relatively symmetric conflict capabilities agree to resolve the conflict by using a random device; however, with sufficiently asymmetric capabilities, conflicts are unavoidable because the stronger agent …

Cheap Talk With Two Audiences: An Experiment, Mikhail Drugov, Roberto Hérnan-Gonzalez, Praveen Kujal, Marta Troya Martinez

ESI Working Papers

In this paper we experimentally test strategic information transmission between one informed and two uninformed agents in a cheap-talk game. We find evidence of the "disciplining" effect of public communication as compared to private; however, it is much weaker than predicted by the theory. Adding a second receiver naturally increases the complexity of strategic thinking when communication is public. Using the level-k model, we exploit the within subject design to show how individuals decrease their level-k in public communication. Surprisingly, we find that individuals become more sophisticated when they communicate privately with two receivers rather than one.

Do Prediction Markets Aid Defenders In A Weak‐Link Contest?, Cary Deck, Li Hao, David Porter

ESI Working Papers

Laboratory experiments have demonstrated that prediction market prices weakly aggregate the disparate information of the traders about states (moves) of nature. However, in many practical applications one might want to predict the move of a strategic participant. This is particularly important in aggressor‐defender contests. This paper reports a set of such experiments where the defender may have the advantage of observing a prediction market on the aggressor’s action. The results of the experiments indicate that: the use of prediction markets does not increase the defender’s win rate; prediction markets contain reliable information regarding aggressors’ decisions, namely excess bid information, that …

Recalibrational Emotions And The Regulation Of Trust-Based Behaviors, Eric Schniter, Timothy W. Shields

ESI Working Papers

Though individuals differ in the degree to which they are predisposed to trust or act trustworthy, we theorize that trust-based behaviors are universally determined by the calibration of conflicting short- and long-sighted behavior regulation programs, and that these programs are calibrated by emotions experienced personally and interpersonally. In this chapter we review both the main-stream and evolutionary theories of emotions that philosophers, psychologists, and behavioral economists have based their work on and which can inform our understanding of trust-based behavior regulation. The standard paradigm for understanding emotions is based on mapping their positive and negative affect valence. While Valence Models …

Religious Identity And The Provision Of Public Goods: Evidence From The Indian Princely States, Latika Chaudhary, Jared Rubin

ESI Working Papers

Religious identity affects preferences and can consequently affect policy. We propose two mechanisms through which a ruler's religious identity can affect public good provision: i) greater provision of goods in regions where more subjects are the ruler's co-religionists, and ii) lower provision of goods where private markets provide a substitute to the ruler's co-religionists. Empirically, identifying the causal effect of religious identity on policy is often impossible, since the religious identity of rulers rarely changes over time and place. We address this problem by exploiting the variation in the religion of rulers in the Indian Princely States in the early …

Commitment Problems In Conflict Resolution, Erik O. Kimbrough, Jared Rubin, Roman M. Sheremeta, Timothy W. Shields

ESI Working Papers

Commitment problems are inherent to non-binding conflict resolution mechanisms, since an unsatisfied party can ignore the resolution and initiate conflict. We provide experimental evidence suggesting that even in the absence of binding contractual agreements individuals often avoid conflict by committing to the outcome of a conflict resolution mechanism. Commitment problems are mitigated to a greater extent for groups who opt-in to the conflict resolution mechanism, but only when opting-in is costly. Although conflict rates are higher when opting-in is costly than when it is free or exogenously imposed, commitment problems are greatly reduced amongst those groups who choose to opt-in.

Prediction Markets In The Laboratory, Cary Deck, David Porter

ESI Working Papers

"The idea that there is wisdom from the collective has been forcefully described in “The Wisdom of the Crowds” by James Surowiecki, who argues that the aggregation of information in groups results in better decisions than those that are afforded by any single member of the group. Markets, like opinion polls, are one mechanism for aggregating disparate pieces of information. The aggregation properties of prices were first noted by Hayek (1945) and were formally examined by Muth (1961). In particular, Hayek argues that market prices serve the purpose of sharing and coordinating local and personal knowledge, while Muth shows that …

The Impact Of Competition On Prices With Numerous Firms, Xavier Gabaix, David Laibson, Deyuan Li, Hongyi Li

ESI Working Papers

We use extreme value theory (EVT) to develop insights about price theory. Our analysis reveals detail-independent equilibrium properties that characterize a large family of models. We derive a formula relating equilibrium prices to the level of competition. When the number of rms is large, markups are proportional to 1= (nF' [F^-1 (1- 1/n)], where F is the random utility noise distribution and n is the number of rms. This implies prices are pinned down by the tail properties of the noise distribution and that prices are independent of many other institutional details. The elasticity of the markup with respect to …

Association Of Family Structure And Glycemic Control In Adolescents With Type 1 Diabetes: Risk And Protective Factors, Laura Jean Caccavale

Theses and Dissertations

Youth with type 1 diabetes (T1D) from single-parent families are more likely to be in poorer glycemic control (HbA1c). Demographic trends indicate more households are composed of unmarried adults and fewer youths. Family density, or a youth: adult ratio, may be a more salient factor than single-parent status in the association with glycemic control. Data from 257 adolescents aged 11-14 years (M = 12.84) at two different sites were collected as part of a randomized control trial of a treatment intervention designed to increase parent involvement and prevent deterioration of adolescent diabetes disease care. Single-parent status was determined by parental …

Feminism, Breastfeeding, And Society, Jen Bracken-Hull

AWE (A Woman’s Experience)

A dichotomy exists among feminists regarding the views and contributions of breastfeeding. Across several waves of feminism women have argued for and against breastfeeding. Until recently, breastfeeding (regarding the bearing and nurturing of children) was seen as a responsibility that prevented women from participating in public circles. This article delineates the general contributions made by women who breastfeed including biological, social, emotional, and personal factors. Changes and accommodations are required for women who choose to breastfeed to not be disadvantaged.

All The Missing Souls: A Personal History Of The War Crimes Tribunals By David Sheffer, Jennifer Laws

Faculty Scholarship

David Scheffer’s memoir records his firsthand experiences as the primary U.S. representative in the processes of building five war crimes tribunals between 1993 and 2006: the International Criminal Tribunal for the former Yugoslavia, the International Criminal Tribunal for Rwanda, the Special Court for Sierra Leone, the Extraordinary Chambers in the Court of Cambodia, and the International Criminal Court. This review analyzes the strengths and weaknesses of his work and makes recommendations to libraries regarding selection for their collections.

Micro-Finance Competition: Motivated Micro-Lenders, Double-Dipping And Default, Brishti Guha, Prabal Roy Chowdhury

Research Collection School Of Economics

We develop a tractable model of competition among motivated MFIs. We find that equilibria may or may not involve double-dipping (and consequently default), with there being double-dipping whenever the MFIs are very profit-oriented. Moreover, in an equilibrium with double-dipping, borrowers who double-dip are actually worse off compared to those who do not. Further, for intermediate levels of motivation, there can be multiple equilibria, with a doubledipping equilibrium co-existing with a no default equilibrium. Interestingly, an increase in MFI competition can lower efficiency, as well as increase the extent of double-dipping and default. Further, the interest rates may go either way, …

Comparing Local Models Of Agrarian Transition In China, Qian Forrest Zhang

Research Collection School of Social Sciences

The development of markets and the penetration of capital into agriculture have started the agrarian transition in rural China, which is transforming smallholding, household-based agriculture into various forms of capitalistic production. This again raises in a new historical and social context the long-debated question in the agrarian transition literature: Can family farms survive the onslaught of capitalist agriculture based on wage labor and what shapes the confrontation between family farms and agro-capital? I argue that it is the local political economy—rather than some natural obstacles in agriculture to the penetration of capitalism—that shapes this confrontation and gives rise to a …

Intertemporal Substitution In Maternal Labor Supply: Evidence Using State School Entrance Age Laws, Rashmi Rekha Barua

Research Collection School Of Economics

I propose a new framework to study the intertemporal labor supply hypothesis. I use an exogenous source of variation in maternal net earning opportunities, generated through school entrance age of children, to study intertemporal labor supply behavior. Employing data from the 1980 US Census and the NLSY, I estimate the effect of a one year delay in school attendance on long run maternal labor supply. IV estimates imply that having a 5 year old enrolled in school increases labor supply measures for married women, with no younger children, by between 7 to 34 percent. Further, using a sample of 7 …

Monetary Regime Choice In Singapore: Would A Tayor Rule Outperform Exchange-Rate Management?, Hwee Kwan Chow, G.C. Lim, P. Mcnelis

Research Collection School Of Economics

This paper adopts a dynamic stochastic general equilibrium-vector autorgressive (DSGE-VAR) approach to examine the managed exchange-rate system at work in Singapore. We examine if the country has any reason to fear floating the exchange rate and adopting a Taylor rule. Our results show that, in terms of overall inflation volatility, the exchange rate rule has a comparative advantage over the Taylor rule when export price shocks are the major sources of real volatility, while a Taylor rule dominates when domestic productivity shocks drive real volatility. The exchange-rate rule also dominates the Taylor rule for reducing inflation persistence.

No Pass No Drive: Education And Allocation Of Time, Rashmi Rekha Barua, Marian Vidal-Fernandez

Research Collection School Of Economics

Since the late 1980s, several states in the US have introduced No Pass No Drive (NPND) laws that set minimum academic requirements for teenagers under 18 to obtain a driving license. Using data from the U.S. Census and Monitoring the Future (MTF) survey, we exploit cross-state, cross-cohort and cross-time variation in NPND laws to study their effect on educational outcomes and allocation of time among teenagers. Estimates using the Census show that NPND laws have a positive and significant effect on both years of completed schooling and the probability of high school completion among boys and blacks, but not girls. …

Can A Financial Conditions Index Guide Monetary Policy? The Case Of Singapore, Hwee Kwan Chow

Research Collection School Of Economics

In this study, we explore the issue of whether a financial conditions index can serve as a useful guide to monetary policy in the context of Singapore. To this end, we construct an index that comprises not only the usual monetary variables like interest rates, exchange rates and credit expansions but also asset prices such as stock prices and house prices. The choice of these constituent series is motivated by the role they play in the monetary transmission mechanism with consideration given to the key role leverage plays in modern business cycles and the risk-taking channel magnified by the prolonged …

Qml Estimation Of Dynamic Panel Data Models With Spatial Errors, Liangjun Su, Zhenlin Yang

Research Collection School Of Economics

We propose quasi maximum likelihood (QML) estimation of dynamic panel models with spatial errors when the cross-sectional dimension n is large and the time dimension T is fixed. We consider both the random effects and fixed effects models and derive the limiting distributions of the QML estimators under different assumptions on the initial observations. We propose a residual-based bootstrap method for estimating the standard errors of the QML estimators. Monte Carlo simulation shows that both the QML estimators and the bootstrap standard errors perform well in finite samples under a correct assumption on initial observations, but may perform poorly when …

Nonparametric Dynamic Panel Data Models: Kernel Estimation And Specification Testing, Liangjun Su, Xun Lu

Research Collection School Of Economics

Motivated by the first differencing method for linear panel data models, we propose a class of iterative local polynomial estimators for nonparametric dynamic panel data models with or without exogeous regressors. The estimators utilize the additive structure of the first-differenced model, the fact that the two additive components have the same functional form, and the unknown function of interest is implicitly defined as a solution of a Fredholm integral equation of the second kind. We establish the uniform consistency and asymptotic normality of the estimators. We also propose a consistent test for the correct specification of linearity in typical dynamic …

Variable Selection In Nonparametric And Semiparametric Regression Models, Liangjun Su, Yonghui Zhang

Research Collection School Of Economics

This chapter reviews the literature on variable selection in nonparametric and semiparametric regression models via shrinkage. We highlight recent developments on simultaneous variable selection and estimation through the methods of least absolute shrinkage and selection operator (Lasso), smoothly clipped absolute deviation (SCAD) or their variants, but restrict our attention to nonparametric and semiparametric regression models. In particular, we consider variable selection in additive models, partially linear models, functional/varying coefficient models, single index models, general nonparametric regression models, and semiparametric/nonparametric quantile regression models.

Non-Normality And Heteroscedasticity Robust Lm Tests Of Spatial Dependence, Badi H. Baltagi, Zhenlin Yang

Research Collection School Of Economics

The standard LM tests for spatial dependence in linear and panel regressions are derived under the normality and homoskedasticity assumptions of the regression disturbances. Hence, they may not be robust against non-normality or heteroskedasticity of the disturbances. Following Born and Breitung (2011), we introduce general methods to modify the standard LM tests so that they become robust against heteroskedasticity and non-normality. The idea behind the robustification is to decompose the concentrated score function into a sum of uncorrelated terms so that the outer product of gradient (OPG) can be used to estimate its variance. We also provide methods for improving …

Deactivation By Unpriming: Does Decrease Of Influence Mean Lowering Of Activation Level?, Lay See Ong, Jennifer Yuk-Yue Tong, Jolene H. Tan

Research Collection School of Social Sciences

Question: Unpriming means a decrease in the influence of primed knowledge, but does it also mean a lowered activation level? Method: Measuring the effect of unpriming with Lexical Decision Task instead of random answering. Findings: The answer is NO. Reaction times were faster after individuals first acted upon the primed concept (unpriming).

Secularity, Religion And The Possibilities For Religious Citizenship, Lyn Parker, Chang Yau Hoon

Research Collection School of Social Sciences

Scholarly predictions of the secularization of the world have proven premature. We see a heterogeneous world in which religion remains a significant and vital social and political force. This paper reflects critically upon secularization theory in order to see how scholars can productively respond to the, at least partly, religious condition of the world at the beginning of the twenty first century. We note that conventional multiculturalism theory and policy neglects religion, and argue the need for a reconceptualization of understanding of religion and secularity, particularly in a context of multicultural citizenship — such as in Australia and Indonesia. We …

The Spirit-Mediums Of Singkawang: Performing Peoplehood Of West Kalimantan, Margaret Chan

Research Collection School of Social Sciences

Chinese New Year in the West Kalimantan town of Singkawang is marked by a parade featuring hundreds of possessed spirit-mediums performing self-mortification and blood sacrifice. The event is a huge tourist draw, but beyond the spectacle, deeper meanings are enacted. The spirit-medium procession stages a fraternity of Dayak, Malay and Chinese earth gods united in the purpose of exorcising demons from the neighborhood. The self-conscious presentation of the Chinese as brethren among pribumi [sons-of-the-soil] Dayak and Malay, proposes the Chinese as belonging to the ‘peoplehood’ of West Kalimantan.
