Economic Voting In The Developing World, Rafael Oganesyan

UNLV Theses, Dissertations, Professional Papers, and Capstones

A plethora of ink has been spilled demonstrating the relationship between economics and voter behavior. Unfortunately, the overwhelming majority of scholarship has concentrated on the empirical assessment of economic voting within the context of developed countries. The present thesis widens the scope of study by testing the applicability of the classic economic voting theory (CEVT) strictly within developing countries. The results suggest that while voters in developing countries do take the economy into account, they do so in a manner that's partially different from what CEVT predicts. Voters in developing countries simultaneously assume both retrospective sociotropic and prospective sociotropic characteristics. …

Development And Testing Of The Home Safety And Beautification Checklist With Mothers Referred For Child Neglect And Substance Abuse, Michelle Pitts

UNLV Theses, Dissertations, Professional Papers, and Capstones

Unintentional injury is the leading cause of death among children in the United States accounting for nearly 40 percent of deaths in this age group. Approximately 50 percent of nonfatal injuries, and 40 percent of fatalities, occur in and around the home. Elevated rates of child injury in the home environment are associated with parental substance abuse and neglectful behaviors. Childhood injuries are preventable, yet practical and cost-effective measures to identify child home safety risks are limited. This study involved a retrospective preliminary examination of the Home Safety and Beautification Checklist (HSBC) in a sample of drug-abusing mothers referred by …

The Wetsuit Effect: Physiological Response To Wearing A Wetsuit, Aaron Prado

UNLV Theses, Dissertations, Professional Papers, and Capstones

The purpose of this study was to investigate the effects of wearing a wetsuit on resting cardiovascular parameters (mean arterial pressure (MAP), rate-pressure product (RPP), and heart rate variability (HRV)). Furthermore, the position (i.e., upright vs. prone) as well as the wetsuit size were explored as possible factors that influence the cardiovascular parameters. Twelve male participants (79.1±5.1 kg, 178.4±2.9 cm, 33.3±12.1 years) granted written consent and were assigned two wetsuits based on height, weight, and corresponding manufacturer recommendations. SWS signified the smallest possible wetsuit the subject could fit into according to recommendations, LWS signified the largest wetsuit the subject could …

Relationship Between Child Behavior Problems, Parental Stress, Child Abuse Potential, And Substance Use Among Mothers In The Child Welfare System, Kendra Tracy

UNLV Theses, Dissertations, Professional Papers, and Capstones

Substance abuse, elevated levels of child behavior problems, and high stress are common among mothers who maltreat their children. However, there is a dearth of research that investigates variables associated with specific types of maltreatment, such as child neglect. Complicating matters, contradictory results between studies have been found among the available research. The present study extends research in this area by investigating the relationships between substance abuse, child behavior problems, parental stress, and child abuse potential in a sample of neglectful mothers with co-occurring substance use disorders. A model is proposed in which parental stress mediates the relationship between child …

The Role Of Chief Diversity Officers In Institutionalizing Diversity And Inclusion: A Multiple Case Study Of Three Exemplar Universities, Cynthia D. Dávalos Phd

Dissertations

Due to demographic shifts and the changing political and economic landscape, universities are experiencing increased demands to produce a culturally competent and well-trained globally minded workforce. To address these demands in a systematic manner, several universities have created a new senior level administrative position to direct campus diversity and inclusion efforts. This position known universally in academia as the Chief Diversity Officer (CDO) is responsible for institutionalizing diversity and inclusion so that diversity moves from the margins of the university to the center and becomes a standard way of thinking and doing business. Given this high-level executive leadership design, the …

Leadership In African American Politics: The Role Of President Obama On The Issue Of Same-Sex Marriage, Kevin Christopher Faulk

Graduate Theses and Dissertations

In 2008, African Americans overwhelmingly supported Senator Obama in his bid for the Presidency. Their supported averaged at 95% of African American voters. At the same time that Senator Obama was on the ballet, Prop 8 - legislation designed to amend California's Constitution to define marriage as between a man and woman - was passed with a large majority of African American support. Why did strong Democrats vote in favor of a law that most Democrats rejected? Previous research has concluded it was the role of the Black Church in African American politics that moves the community to a more …

Assessing Food Policy Options In Asia To Reduce Price Volatility Of Rice Market, Ranjitsinh Mane

Graduate Theses and Dissertations

Rice is a staple food in Asia and its prices at national and international levels are largely influenced by different policy actions of trading countries. The consequence of the 2008 food crisis was food riots and rationing of rice in many nations. The ASEAN Plus Three (APT) countries have adopted an institutional framework called ASEAN Plus Three Emergency Rice Reserves (APTERR) to address food security concerns of ASEAN countries that may arise due to climate change, supply chain disruptions or price speculation in the regional rice market. The RICEFLOW model is used to study the effectiveness of the strategic grain …

Daily Racial Microaggressions And Ethnic Identification Among Native American Young Adults, Merrill D. Jones, Renee Vickerman Galliher

Psychology Faculty Publications

The current study investigated 114 Native American young adults’ experiences of racial microaggressions, and links between microaggression experiences and self-reported ethnic and cultural identification. Microaggressions were assessed using the Daily Racial Microaggressions scale, Short Form (DRM). Ethnic identity and cultural participation were assessed using the Multigroup Ethnic Identity Measure (MEIM) and the Orthogonal Cultural Identification Scale (OCIS). Participants reported strong identification with their Native/indigenous ethnicity, along with stronger commitment than exploration on the two MEIM subscales. On the OCIS, participants reported moderately strong identification with Native culture and practices, with strong identification with White American culture. Females reported higher White …

A Description Of Vocalizations And Their Association With Mouthing Behaviors And Social Context In Bottlenose Dolphins, Tursiops Truncatus, Christina Elyse Perazio

Master's Theses

Dolphin communication is multimodal and incorporates physical behaviors and vocalizations. Dolphins often exchange information with conspecifics using different types of vocalizations, and these vocalizations are sometimes associated with specific behaviors. However, the relationship of vocalization type and mouthing behavior type has not been investigated. This thesis examines simultaneous acoustic and visual recordings of bottlenose dolphins (Tursiops truncatus) to determine the relationship between type of mouthing behavior and type of vocalization (whistle, whistle-squawk, chirp, moan, burst-pulse type A, burst-pulse type B, and click trains). The role of the social context of a mouthing behavior is also evaluated. Data were obtained opportunistically …

Bayesian Testing Volatility Persistence In Stochastic Volatility Models With Jumps, Xiaobin Liu, Yong Li

Research Collection School Of Economics

Whether or not there is a unit root persistence in volatility of financial assets has been a long-standing topic of interest to financial econometricians and empirical economists. The purpose of this article is to provide a Bayesian approach for testing the volatility persistence in the context of stochastic volatility with Merton jump and correlated Merton jump. The Shanghai Composite Index daily return data is used for empirical illustration. The result of Bayesian hypothesis testing strongly indicates that the volatility process doesn’t have unit root volatility persistence in this stock market.

Econometric Analysis Of Continuous Time Models: A Survey Of Peter Phillips' Work And Some New Results, Jun Yu

Research Collection School Of Economics

Econometric analysis of continuous time models has drawn the attention of Peter Phillips for 40 years, resulting in many important publications by him. In these publications he has dealt with a wide range of continuous time models and the associated econometric problems. He has investigated problems from univariate equations to systems of equations, from asymptotic theory to finite sample issues, from parametric models to nonparametric models, from identification problems to estimation and inference problems, from stationary models to nonstationary and nearly nonstationary models. This paper provides an overview of Peter Phillips' contributions in the continuous time econometrics literature. We review …

Robustify Financial Time Series Forecasting With Bagging, Sainan Jin, Liangjun Su, Aman Ullah

Research Collection School Of Economics

In this paper we propose a revised version of (bagging) bootstrap aggregating as a forecast combination method for the out-of-sample forecasts in time series models. The revised version explicitly takes into account the dependence in time series data and can be used to justify the validity of bagging in the reduction of mean squared forecast error when compared with the unbagged forecasts. Monte Carlo simulations show that the new method works quite well and outperforms the traditional one-step-ahead linear forecast as well as the nonparametric forecast in general, especially when the in-sample estimation period is small. We also find that …

Specification Test For Panel Data Models With Interactive Fixed Effects, Liangjun Su, Sainan Jin, Yonghui Zhang

Research Collection School Of Economics

In this paper, we propose a consistent nonparametric test for linearity in a large dimensional panel data model with interactive fixed effects. Both lagged dependent variables and conditional heteroskedasticity of unknown form are allowed in the model. We estimate the model under the null hypothesis of linearity to obtain the restricted residuals which are then used to construct the test statistic. We show that after being appropriately centered and standardized, the test statistic is asymptotically normally distributed under both the null hypothesis and a sequence of Pitman local alternatives by using the concept of conditional strong mixing that was recently …

Jackknife Model Averaging For Quantile Regressions, Xun Lu, Liangjun Su

Research Collection School Of Economics

In this paper, we consider the problem of frequentist model averaging for quantile regression (QR) when all the M models under investigation are potentially misspecified and the number of parameters in some or all models is diverging with the sample size n. To allow for the dependence between the error terms and the regressors in the QR models, we propose a jackknife model averaging (JMA) estimator which selects the weights by minimizing a leave-one-out cross-validation criterion function and demonstrate that the jackknife selected weight vector is asymptotically optimal in terms of minimizing the out-of-sample final prediction error among the given …

Identifying Latent Structures In Panel Data, Liangjun Su, Zhentao Shi, Peter C. B. Phillips

Research Collection School Of Economics

This paper provides a novel mechanism for identifying and estimating latent group structures in panel data using penalized regression techniques. We focus on linear models where the slope parameters are heterogeneous across groups but homogenous within a group and the group membership is unknown. Two approaches are considered — penalized least squares (PLS) for models without endogenous regressors, and penalized GMM (PGMM) for models with endogeneity. In both cases we develop a new variant of Lasso called classifier-Lasso (C-Lasso) that serves to shrink individual coefficients to the unknown group-specific coefficients. C-Lasso achieves simultaneous classification and consistent estimation in a single …

Unilateral Emissions Mitigation, Spillovers, And Global Learning, Shurojit Chatterji, Sayantan Ghosal, Sean Walsh, John Whalley

Research Collection School Of Economics

What's the role of unilateral measures in global climate change mitigation in a post-Durban, post 2012 global policy regime? We argue that under conditions of preference heterogeneity, unilateral emissions mitigation at a subnational level may exist even when a nation is unwilling to commit to emission cuts. We establish that under certain assumptions, in a global strongly connected network of countries, learning the costs of switching to a low emissions activity can result in a universal adoption of such activities. We analyze the features of a policy proposal that could accelerate convergence to a low carbon world in the presence …

A Flexible And Automated Likelihood Based Framework For Inference In Stochastic Volatility Models, Hans J. Skaug, Jun Yu

Research Collection School Of Economics

The Laplace approximation is used to perform maximum likelihood estimation of univariate and multivariate stochastic volatility (SV) models. It is shown that the implementation of the Laplace approximation is greatly simplified by the use of a numerical technique known as automatic differentiation (AD). Several algorithms are proposed and compared with some existing maximum likelihood methods using both simulated data and actual data. It is found that the new methods match the statistical efficiency of the existing methods while significantly reducing the coding effort. Also proposed are simple methods for obtaining the filtered, smoothed and predictive values for the latent variable. …

Minimum Investment Requirements, Financial Market Globalization, And Symmetry Breaking, Haiping Zhang

Research Collection School Of Economics

We incorporate wealth heterogeneity and the minimum investment requirements in the model of Matsuyama (2004, Econometrica) and provide a complete characterization of symmetry breaking. In particular, we identify the extensive margin of investment as a key channel through which the interest rate may respond positively to capital accumulation, or equivalently, the interest rate can be higher in the rich than in the poor countries. Then, financial market globalization may lead to “uphill” capital flows from the poor to the rich countries, which widens the initial cross-country income gap and leads to income divergence among inherently identical countries, a phenomenon that …

Engineering, Teaching, And Technology: A Nationwide Assessment Of Instructional Internet Use By Engineering Faculty, Alexander Lehman Phd

Dissertations

There has been an explosion of internet use among college students over the last decade for at least two important reasons: the proliferation of available resources and the arrival of a digital native generation to university campuses. Not surprisingly, engineering students are entering undergraduate programs possessing a much different skill set than previous generations, which has led to a decline in the popularity of traditional engineering pedagogy. Numerous conceptual models have been developed in the field of instructional technology, as researchers have attempted to classify and effectively integrate new technology practices into 21st century educational contexts. One of the most …

Educating The Whole Child: Evidence Of Health And Wellness Instruction In The Schools Serving Low-Income Students, Andria M. Shook Phd

Dissertations

Educators in the United States are expressing concern about student physical and mental well-being. Childhood obesity has more than doubled in the past three decades, and today, one in five children experiences symptoms of mental illness. Low-income children are especially subject to these conditions. The long-term consequences for the country as a whole are significant. Schools are particularly well placed to address these problems by supporting the well-being of the whole child. Efforts have begun in select schools and districts to incorporate health and wellness instruction into the school day. This study identifies existing health and wellness components that three …

Assessing Market Failures In Export Pioneering Activities: A Structural Estimation Approach, Shang-Jin Wei, Ziru Wei, Jianhuan Xu

Research Collection School Of Economics

The paper provides a first structural-estimation-based assessment of an influential hypothesis that export pioneers are too few relative to social optimum due to knowledge spillover in new market explorations. Such market failure requires two inequalities to hold simultaneously: the discovery cost is greater than any individual firm’s expected profit but Smaller than the sum of all potential exporters’ expected profits. Neither has to hold in the data. We estimate the structural parameters based on the customs data of Chinese electronics exports. While we find positive discover cost and spillovers, "missing pioneers" are nonetheless a low probability event.

Unit Roots In Life: A Graduate Student Story, Peter C. B. Phillips

Research Collection School Of Economics

What follows is a graduate student story. It draws on the first part of the speech I gave that evening at the NZESG conference dinner. It mixes personal reflections with recollections of the extraordinary New Zealanders who shaped my thinking as a graduate student and beginning researcher-people who have had an enduring impact on my work and career as an econometrician. The story traces out these human initial conditions and unit roots that figure in my early life of teaching and research.

Nonlinearity Induced Weak Instrumentation, Ioannis Kasparis, Peter C. B. Phillips, Tassos Magdalinos

Research Collection School Of Economics

In regressions involving integrable functions we examine the limit properties of instrumental variable (IV) estimators that utilise integrable transformations of lagged regressors as instruments. The regressors can be either I(0) or nearly integrated (NI) processes. We show that this kind of nonlinearity in the regression function can significantly affect the relevance of the instruments. In particular, such instruments become weak when the signal of the regressor is strong, as it is in the NI case. Instruments based on integrable functions of lagged NI regressors display long range dependence and so remain relevant even at long lags, continuing to contribute to …

Social Tipping Points And Earth Systems Dynamics, R.A. Bentley, E. Maddison, P. Ranner, J. Bissell, C. Caiado, P. Bhatanacharoen, Timothy Adrian Robert Clark, Botha M., Akinbami F., Hollow M., Michie R., Huntley B., Curtis S., Garnett P.

Research Collection Lee Kong Chian School Of Business

Recently, Early Warning Signals (EWS) have been developed to predict tipping points in Earth Systems. This discussion highlights the potential to apply EWS to human social and economic systems, which may also undergo similar critical transitions. Social tipping points are particularly difficult to predict, however, and the current formulation of EWS, based on a physical system analogy, may be insufficient. As an alternative set of EWS for social systems, we join with other authors encouraging a focus on heterogeneity, connectivity through social networks and individual thresholds to change.

A Combined Approach To The Inference Of Conditional Factor Models, Yan Li, Liangjun Su, Yuewu Xu

Research Collection School Of Economics

This paper develops a new methodology for estimating and testing conditional factor models in finance. We propose a two-stage procedure that naturally unifies the two existing approaches in the finance literature -- the parametric approach and the nonparametric approach. Our combined approach possesses important advantages over both methods. Using our two-stage combined estimator, we derive new test statistics for investigating key hypotheses in the context of conditional factor models. Our tests can be performed on a single asset or jointly across multiple assets. We further propose a novel test to directly check whether the parametric model used in our first …

Shrinkage Estimation Of Regression Models With Multiple Structural Changes, Junhui Qian, Liangjun Su

Research Collection School Of Economics

In this paper we consider the problem of determining the number of structural changes in multiple linear regression models via group fused Lasso (least absolute shrinkage and selection operator). We show that with probability tending to one our method can correctly determine the unknown number of breaks and the estimated break dates are sufficiently close to the true break dates. We obtain estimates of the regression coefficients via post Lasso and establish the asymptotic distributions of the estimates of both break ratios and regression coefficients. We also propose and validate a data-driven method to determine the tuning parameter. Monte Carlo …

The People Want The Fall Of The Regime: Schooling, Political Protest, And The Economy, Filipe R. Campante, Davin Chor

Research Collection School Of Economics

We provide evidence that economic circumstances are a key intermediating variable for understanding the relationship between schooling and political protest. Using the World Values Survey, we find that individuals with higher levels of schooling, but whose income outcomes fall short of that predicted by their biographical characteristics, in turn display a greater propensity to engage in protest activities. We discuss a number of interpretations that are consistent with this finding, including the idea that economic conditions can affect how individuals trade off the use of their human capital between production and political activities. Our results could also reflect a link …

Explaining Implicit And Explicit Affective Linkages In It Teams: Facial Recognition, Emotional Intelligence, And Affective Tone, Mary M. Dunaway

Graduate Theses and Dissertations

Over 80 percent of task work in organizations is performed by teams. Most teams operate in a more fluid, dynamic, and complex environment than in the past. As a result, a growing body of research is beginning to focus on how teams’ emotional well-being can benefit the effectiveness of workplace team efforts. These teams are required to be adaptive, to operate in ill-structured environments, and to rely on technology more than ever before. However, teams have become so ubiquitous that many organizations and managers take them for granted and assume they will be effective and productive. Because of the increased …

Effects Of Parental Modeling On The Development Of Panic-Relevant Escape And Avoidance Among Adolescents: An Experimental Study Using A Biological Challenge Procedure, Liviu Bunaciu

Graduate Theses and Dissertations

Escape and avoidance behaviors play a prominent role in the maintenance of panic-spectrum difficulties and may also be implicated in the development of such problems. Although the current state of the literature regarding the etiology of these emotion-regulation strategies is relatively underdeveloped, it appears that learning experiences involving parental modeling of such behaviors may be instrumental in the development of panic-relevant escape and avoidance. Given that no tests of such a conceptualization exist at this time, the current study proposed an initial experimental examination of whether parental modeling of defensive reactivity during a well-established biological challenge could impact panic-relevant escape …
