Development And Feasibility Pilot Study Of Indigenous Recovery Planning: A Community-Engaged Approach To Addressing Substance Use In A Native Community, Monica C Skewes, Vivian M Gonzalez, Julie A Gameon, Adriann Ricker, Shannon Martell, Martel Reum, Shannon Holder

Faculty, Staff and Student Publications

Although Native (American Indian and Alaska Native [AI/AN]) populations have high rates of abstinence from alcohol, health problems associated with substance use remain a pressing concern in many AI/AN communities. As part of a longstanding community-based participatory research (CBPR) project involving five years of relationship building and three preliminary studies, our team of academic and community co-researchers developed a culturally grounded intervention to facilitate recovery from substance use disorders among tribal members from a rural AI reservation. Our Indigenous Recovery Planning (IRP) intervention consists of six weekly sessions and aims to provide inroads to existing resources in the community, affirm …

The Influence Of Societal Nationalist Sentiment On Trade Flows, Douglas Dow, Ilya Cuypers

Research Collection Lee Kong Chian School Of Business

In recent years, the world has witnessed a backlash against globalization and a rise in populist and nationalist movements around the world. However, there appears to be little empirical research concerning how these movements, and especially nationalist sentiment, actually influence trade. Therefore, we explore how and when nationalist sentiment within a country influences trade. Our results indicate that the effect of nationalist sentiment on imports is mediated by lower participation in free trade agreements (FTAs) but not via tariffs. Furthermore, we are unable to confirm support for a direct effect of nationalist sentiment on imports, as predicted by the consumer …

Social Network Centrality And The Corporate Environment: The Case Of Sexual Diversity Policies, Nuttavuth Nundhapana, Chiyachantana N. Chiraphol, Kuan Yong David Ding, Sirimon Treepongkaruna

Research Collection Lee Kong Chian School Of Business

We study the external influence of social capital, measured by Facebook's (now Meta) Social Connectedness Index, on a firm's decision to adopt policies that promote a more diverse corporate environment. Recent studies find corporate policies that embrace sexual diversity are beneficial to firms and their stakeholders, thereby contributing to their corporate social responsibility (CSR) and business sustainability. We find that firms with a high social network centrality are more likely to adopt policies and business strategies that support sexual diversity. Moreover, firms that adopt good CSR practices are more likely to implement more inclusive policies such as sexual diversity policies. …

Techniques In Medicine: Ipsilateral Transforaminal Epidural Steroid Injection In Bertolotti’S Syndrome, Peter D Vu, Christopher L Robinson, Omar Viswanath, Ivan Urits, Jamal Hasoon

Faculty, Staff and Student Publications

Bertolotti's syndrome, also known as lumbosacral transitional vertebrae, is a relatively rare spinal condition characterized by an anatomical variation in the lower spine. Conservative approaches such as physical therapy, anti-inflammatory medications and lifestyle modifications may be recommended for mild cases. In more severe cases or when conservative measures fail to provide relief, injections such as may be considered to alleviate pain. This case is unique in that we document a challenging technique of ipsilateral transforaminal epidural steroid injection in a patient with Bertolotti's syndrome.

Models For Estimating Intrinsic R And The Mean Age Of A Population At Stability: Evaluations At The National And Sub-National Level, David A. Swanson

Publications, Reports and Presentations

Using Canada’s provinces and territories in conjunction with the “Cohort Change Ratio” approach to generating a stable population, I test the accuracy of two regression models constructed from national-level data designed to estimate two factors of a population at stability from initial conditions at the sub-national levels: (1) its constant rate of change, denoted here by r'; and (2) mean population age. In a test of accuracy at the national level I find that these models provide reasonably accurate estimates. In the tests at the subnational level, the accuracy, as expected, is less, but the results indicate that the …

Iran's Look East Policy Against Western Countries Through Snyder's Foreign Policy Analysis, Juana Clarentine Emmanuela Greevince De Lucas, Muhammad Rayhan Anandito, Tasya Salsabila Hendrayudha, Septyanto Galan Prakoso

Jurnal Politik

Iran has been in disarray following the United States exit from the JCPOA in 2018. It is due to the increasing number of sanctions reimposed by the West, which harms the Iranian economy. With the current economic downturn, Iran, under President Ebrahim Raisi's leadership, has made efforts to become completely independent from the West by establishing the Look East Policy as its foreign policy. This research analyses why Ebrahim Raisi's administration favoured the Look East Policy as Iranian foreign policy. Data collection techniques used in this study are library research, using secondary data from books, journal articles, official websites, and …

Constitutional, Governance Or Market Failures: China, Climate Change And Energy Transition, Henry S. Gao, Weihuan Zhou

Research Collection Yong Pung How School Of Law

Jinping announced China’s plan to further scale up its Intended Nationally Determined Contributions, aiming at achieving CO2 emissions peak before 2030 and carbon neutrality before 2060.2 A central element of the plan is reducing China’s heavy reliance on coal power. As a result, China’s use of coal already saw a steady decrease between 2013 and 2018. While coal demand increased in 2019 and 2020, new coal power plants approved in 2021 declined by approximately 58% compared to 2020.3 However, the good progress in energy transition was interrupted by the power outage sprawling over 20 provinces in China in September 2021, …

Inclusive Postsecondary Education's Effect On Individuals With Idd: A Systematic Literature Review, Hunter Wolff

University Honors Theses

With the purpose of evaluating the impact of Inclusive Postsecondary Education (IPSE) effects on those experiencing intellectual and/or developmental disabilities (IDD), a systematic literature review was conducted. Proponents of the expansion of these programs often cite participant growth in academic-related skills, socialization, and competitive integrated employment. While several studies document these benefits, few studies present and discuss all the data collectively. This review aims to both locate the data that shows how IPSE programs affect the students within them as well as to provide a location in which all the data can be accessed. A thorough conducting of the research …

Youth Mental Health And Help-Seeking Behaviors, Azya Ripley

University Honors Theses

We know that there is a mental health crisis but that many youth will hesitate to seek out help or will not know how to seek out help. This thesis investigates some factors that represent barriers to youth in asking and getting help from adults for mental health, and how adults can intervene to increase youth's likelihood to be vulnerable and honest in their struggles. Moving forward, I outline some concrete ways to normalize asking for help and to make it easier for youth to access counselors and therapists.

The study examines the historical development of AI in mental health, highlighting its development and advancements that have influenced its current implementations.

In addition to its direct applications in therapy, AI is also examined in the context of its role as a facilitator or "stepping stone" in the delivery of mental health care. AI-driven platforms …

Interrelationships Among The Rice Export Prices Of Major Exporting Countries: In Search Of The Leader And Followers, Khondoker Abdul Mottaleb, Alvaro Durand-Morat

Agricultural Economics and Agribusiness Faculty Publications and Presentations

By examining the econometric interrelationships of rice export prices of India, Thailand, Vietnam, Pakistan, the U.S., Argentina, Brazil, and Uruguay, this study examines the most influential rice-exporting countries in the international rice export market. The sampled countries are the source of more than 80% of the global rice exports. In the process, this study relies on online data portals of the United Nations and country-level sources for aromatic and non-aromatic rice export price information from India, Pakistan, and Thailand. This study employed the Prais-Winsten and Autoregressive Distributive Lag (ARDL) estimation processes with the error correction procedure. Combining the findings from …

Market Assessment Of Fortified Parboiled Rice In Burkina Faso, Alvaro Durand-Morat, Ya-Jane Wang, Imael H.N. Bassole, Lilian Nkengla-Asi, Wei Yang

Agricultural Economics and Agribusiness Faculty Publications and Presentations

Micronutrient deficiency remains a daunting issue in many parts of the world. Effective interventions are needed to deal with the problem, which should consider production and consumption traditions and trends to improve their success. Parboil rice is a growing staple in Burkina Faso, where micronutrient deficiency remains high. This paper assesses the market feasibility of fortified rice through parboiling using a limited-water soaking method. Our findings suggest that consumers are willing to pay a premium for fortified rice versus conventional parboiled rice after they are informed about the importance of the problem and the potential benefits of fortified rice. A …

Face Peace Design Brief #3: Facilitating Training And Education Programs In The Peacebuilding Field, John Porten

Kroc IPJ Research and Resources

Trust-building and social bonding are easier in person — and to some extent in synchronous rather than asynchronous distanced learning. Distance and time differences can make organization of synchronous learning difficult. Differences in access to the internet and other infrastructure issues can exacerbate this problem. Cultural differences and other forms of diversity can also make building trust among students, and between students and teachers, more difficult.

While advances in technology and technique have improved the outcomes of distanced educational programs in recent years, distanced educational models still result in underperformance for the participants when compared to face-to-face programs. Research shows …

Face Peace Design Brief #4: Negotiation And Consensus Building In Hybrid Environments, John Porten

Kroc IPJ Research and Resources

This FACE Peace Design Brief considers negotiation and consensus-building programs using a mix of in-person and distanced elements. Recent advances in technology and cultural shifts brought about by the COVID-19 pandemic have allowed program and event designers to consider a wide variety of tools and practices that allow negotiations and bargaining to happen at a distance or asynchronously.

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

Research Collection School Of Economics

This paper examines methods of inference concerning quantile treatment effects (QTEs) in randomized experiments with matched-pairs designs (MPDs). Standard multiplier bootstrap inference fails to capture the negative dependence of observations within each pair and is therefore conservative. Analytical inference involves estimating multiple functional quantities that require several tuning parameters. Instead, this paper proposes two bootstrap methods that can consistently approximate the limit distribution of the original QTE estimator and lessen the burden of tuning parameter choice. Most especially, the inverse propensity score weighted multiplier bootstrap can be implemented without knowledge of pair identities.

Life Satisfaction Changes And Adaptation In The Covid-19 Pandemic: Evidence From Singapore, Terence C. Cheng, Seonghoon Kim, Kanghyock Koh

Research Collection School Of Economics

We provide novel evidence on how COVID-19 affected overall life satisfaction using a monthly longitudinal survey of middle-aged and older Singaporeans. We study how the subjective well-being of individuals evolves over the course of 18 months including the outbreak of the pandemic, the implementation of the lockdown and the spike of cases due to the delta variant in a country where COVID-19 is controlled in a sustained manner. Using an event-study design framework, we find large declines in overall life satisfaction in the lead-up to and following the lockdown. Fifteen months after the outbreak of the pandemic, and 13 months …

Obfuscation And Rational Inattention, Aljoscha Janssen, Johannes Kasinger

Research Collection School Of Economics

We study the behavior of duopolistic firms that can obfuscate their prices before competing on price. Obfuscation affects the rational inattentive consumers' optimal information strategy, which determines the probabilistic demand. Our model advances related models by allowing consumers to update their unrestricted prior beliefs with an informative signal of any form. We show that the game may result in an obfuscation equilibrium with high prices or a transparency equilibrium with low prices and no obfuscation, providing an argument for market regulation. Obfuscation equilibria cease to exist for low information costs and if one firm seems a priori considerably more attractive.

Migration And Resource 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 equilibrium model with input and output distortions and migration, we show that the firm-level frictions are less dispersed and less correlated with firm productivity in richer prefectures. Counterfactual exercises show that reducing the within-prefecture misallocation increases aggregate welfare, discourages migration toward large prefectures, and reduces spatial inequality. Moreover, internal migration alleviates micro-frictions’ impacts on aggregate welfare and worsens their effects on spatial inequality.

The Distributional Impacts Of Transportation Networks In China, Lin Ma, Yang Tang

Research Collection School Of Economics

We document that the quality of roads and railroads vary substantially over time and space in China, and neglecting these variations biases the distributional impacts of transportation networks. To account for quality differences, we construct a new panel dataset and approximate quality using the design speed of roads and railroads that varies by vintage, class, and terrain at the pixel level. We then build a dynamic spatial general equilibrium model for multiple modes, transportation routes, and forward-looking migration decisions. Our findings demonstrate that disregarding quality differences leads to a median bias of approximately 31% in estimating real wage growth rates …

Panel Data Models With Time-Varying Latent Group Structures, Yiren Wang, Peter C. B. Phillips, Liangjun Su

Research Collection School Of Economics

This paper considers a linear panel model with interactive fixed effects and unobserved individual and time heterogeneities that are captured by some latent group structures and an unknown structural break, respectively. To enhance realism, the model may have different numbers of groups and/or different group memberships before and after the break. With preliminary nuclear norm regularized estimation followed by row- and column-wise linear regressions, we estimate the break point based on the idea of binary segmentation and the latent group structures together with the number of groups before and after the break by sequential testing K-means algorithm simultaneously. It is …

Interim Regret Minimization, Wei He, Jiangtao Li, Kexin Wang

Research Collection School Of Economics

We consider a robust version of monopoly pricing when the seller only knows the bound on valuations and the mean of the distribution of the buyer’s value. The seller seeks to minimize interim regret, the forgone expected revenue due to not knowing the distribution of the buyer’s value. The optimal pricing policy randomizes over a range of prices; the support of the pricing policy is bounded away from zero.

Research Collection School Of Economics

The modern-day classroom is characterized by academic diversity, with students from varied backgrounds and with different levels of prior knowledge. To cater to the diverse abilities of students, this paper explored the use of flipped learning as a teaching approach in an introductory economics course. We investigated the effectiveness of 40 pre-lecture videos covering basic concepts and 27 post-lecture tutorial videos focusing on practice in improving students' exam outcomes, especially for beginners in economics who may require more support from instructors than other students. We collected data about video engagement and students' grades in progress assessments. Surveys were conducted to …

Testing The Dimensionality Of Policy Shocks, Jia Li, Viktor Todorov, Qiushi Zhang

Research Collection School Of Economics

This paper provides a nonparametric test for deciding the dimensionality of a policy shock as manifest in the abnormal change in asset returns' stochastic covariance matrix, following the release of a macroeconomic announcement. We use high-frequency data in local windows before and after the event to estimate the covariance jump matrix, and then test its rank. We find a one-factor structure in the covariance jump matrix of the yield curve resulting from the Federal Reserve's monetary policy shocks prior to the 2007-2009 financial crisis. The dimensionality of policy shocks increased afterwards due to the use of unconventional monetary policy tools.

Invisible Inequalities: Barriers, Challenges, And Opportunities, Hari Bapuji, Gokhan Ertug, Vivek Soundarajan, Jason D. Shaw

Research Collection Lee Kong Chian School Of Business

Inequality is a grand challenge of our times, and management researchers have responded by examining the relationship between business and societal economic inequalities. This research has enhanced our understanding of the nature, sources, and consequences of inequalities, as well as identified actions to address them. However, this effort has predominantly revolved around visible inequalities. We seek to direct greater scholarly attention to invisible inequalities – uneven possession of and access to resources and opportunities to engage in value creation, appropriation, and distribution based on attributes and characteristics that are not readily apparent or noticeable. Expanding the scope of investigations to …

Optimal Inference For Spot Regressions, Tim Bollerslev, Jia Li, Yuexuan Ren

Research Collection School Of Economics

Betas from return regressions are commonly used to measure systematic financial market risks. "Good" beta measurements are essential for a range of empirical inquiries in finance and macroeconomics. We introduce a novel econometric framework for the nonparametric estimation of time-varying betas with high-frequency data. The "local Gaussian" property of the generic continuous-time benchmark model enables optimal "finite-sample" inference in a well-defined sense. It also affords more reliable inference in empirically realistic settings compared to conventional large-sample approaches. Two applications pertaining to the tracking performance of leveraged ETFs and an intraday event study illustrate the practical usefulness of the new procedures.

Tunisian Democracy At A Crossroads: A Comparative Analysis Of Beji Caid Essebsi And Kais Saied Regimes, Nizar Lukman

Jurnal Politik

As a new democracy, Tunisia is quite vulnerable to democratic erosion. The implementation of democracy in the country was quite effective during the leadership of Beji Caid Essebsi, resulting in a high democracy index driven by various policies that supported the implementation of this system. However, Tunisia’s quality of democracy significantly declined since President Kais Saied took power in 2019. The dissolution of Parliament, the prime minister's dismissal, the introduction of freedom of expression for council members, and unilateral electoral reforms aimed at consolidating his power are some cases of proof. This pattern raises questions about the recurring nature of …

Pakistan's Dependence On China For The Second Phase Of Cpec Cooperation In 2020-2021, Agnes Deandra Bangkur

Jurnal Politik

The China-Pakistan Economic Corridor (CPEC), an important component of China's Belt and Road Initiative (BRI), has been a landmark project since its inception in 2015. The project aims to develop a modern Silk Road that increases China's economic reach by capitalizing on Pakistan's strategic geographic position. However, this cooperation has raised concerns about Pakistan's growing dependence on China, posing a risk to the country's long-term stability. Artiel examines the implications of Pakistan's dependence on China within the framework of Dependency Theory, particularly in the continuation of the second phase of CPEC cooperation. By analyzing a wide range of literature and …
