Cooperative Trucks And Drones For Rural Last-Mile Delivery With Steep Roads, Jiuhong Xiao, Ying Li, Zhiguang Cao, Jianhua Xiao

Research Collection School Of Computing and Information Systems

The cooperative delivery of trucks and drones promises considerable advantages in delivery efficiency and environmental friendliness over pure fossil fuel fleets. As the prosperity of rural B2C e-commerce grows, this study intends to explore the prospect of this cooperation mode for rural last-mile delivery by developing a green vehicle routing problem with drones that considers the presence of steep roads (GVRPD-SR). Realistic energy consumption calculations for trucks and drones that both consider the impacts of general factors and steep roads are incorporated into the GVRPD-SR model, and the objective is to minimize the total energy consumption. To solve the proposed …


Leveraging Instagram To Enhance Self-Esteem: A Self-Affirmative Intervention Study And Multilevel Mediation Analysis, Shuna Shiann Khoo, Hwajin Yang, Wei Xing Toh Jan 2024

Leveraging Instagram To Enhance Self-Esteem: A Self-Affirmative Intervention Study And Multilevel Mediation Analysis, Shuna Shiann Khoo, Hwajin Yang, Wei Xing Toh

Research Collection School of Social Sciences

Although studies have consistently indicated that heavier use of social networking sites (SNS) perpetuates poorer self-esteem outcomes, no study has examined potential intervention methods that can yield positive effects from SNS use. We hypothesized that viewing one's Instagram profile would have self-affirmative effects on self-perception because the profile typically showcases curated instrumental positive aspects of self. Furthermore, these self-affirmative effects would indirectly improve state self-esteem via enhanced clarity of self-concept. To test our hypothesis, we designed an experimental intervention study where one group viewed their Instagram profile regularly, while another group viewed a neutral abstract art profile. Using multilevel latent …


Equal Predictive Ability Tests Based On Panel Data With Applications To Oecd And Imf Forecasts, Oguzhan Akgun, Alain Pirotte, Giovanni Urga, Zhenlin Yang Jan 2024

Equal Predictive Ability Tests Based On Panel Data With Applications To Oecd And Imf Forecasts, Oguzhan Akgun, Alain Pirotte, Giovanni Urga, Zhenlin Yang

Research Collection School Of Economics

We propose two types of equal predictive ability (EPA) tests with panels to compare the predictions made by two forecasters. The first type, S-statistics, focuses on the overall EPA hypothesis, which states that the EPA holds, on average, over all panel units and over time. The second type, C-statistics, focuses on the clustered EPA hypothesis where the EPA holds jointly for a fixed number of clusters of panel units. The asymptotic properties of the proposed tests are evaluated under weak and strong cross-sectional dependence. An extensive Monte Carlo simulation shows that the proposed tests have very good finite sample properties, …


Robust Testing For Explosive Behavior With Strongly Dependent Errors, Yui Lim Lui, Peter C. B. Phillips, Jun Yu Jan 2024

Robust Testing For Explosive Behavior With Strongly Dependent Errors, Yui Lim Lui, Peter C. B. Phillips, Jun Yu

Research Collection School Of Economics

A heteroskedasticity-autocorrelation robust (HAR) test statistic is proposed to test for the presence of explosive roots in financial or real asset prices when the equation errors are strongly dependent. Limit theory for the test statistic is developed and extended to heteroskedastic models. The new test has stable size properties unlike conventional test statistics that typically lead to size distortion and inconsistency in the presence of strongly dependent equation errors. The new procedure can be used to consistently time-stamp the origination and termination of an explosive episode under similar conditions of long memory errors. Simulations are conducted to assess the finite …

Lifetime Adversity Predicts Depression, Anxiety, And Cognitive Impairment In A Nationally Representative Sample Of Older Adults In The United States, Sangnam Ahn, Seonghoon Kim, Hongmei Zhang, Aram Dobalian, George Slavich

Research Collection School Of Economics

Objective: Although life stress and adversity have emerged as risk factors for mental health problems and cognitive impairment among older adults, prior studies on this topic have been cross-sectional and based on relatively homogeneous samples. To address these issues, we examined prospective associations between lifetime adversity and symptoms of depression, anxiety, and cognitive impairment in a nationally representative, longitudinal sample of older adults in the U.S. Method: We analyzed data from the Health and Retirement Study (1992-2016). The sample included 3,496 individuals (59.9% female), aged ≥64 years old (M age=76.0 ±7.6 years). We used the individual-level panel data and ordinary …


On The Optimal Forecast With The Fractional Brownian Motion, Xiaohu Wang, Jun Yu, Chen Zhang Jan 2024

On The Optimal Forecast With The Fractional Brownian Motion, Xiaohu Wang, Jun Yu, Chen Zhang

Research Collection School Of Economics

This paper investigates the performance of different forecasting formulas with fractional Brownian motion based on discrete and finite samples. Existing literature presents two formulas for generating optimal forecasts when continuous records are available. One formula relies on a history over an infinite past, while the other is designed for a record limited to a finite past. In reality, only observations at discrete time points over a finite past are available. In this case, the forecasting formula, which has been widely used in the literature, is the one obtained by Gatheral et al. (2018) that truncates and discretizes the formula based …


Internal And Social Sources Shape Judgments About The Mental And Physical Nature Of An Experience, Jacinth Jia Xin Tan, Alexander Karan, Dolores Albarracin Jan 2024

Internal And Social Sources Shape Judgments About The Mental And Physical Nature Of An Experience, Jacinth Jia Xin Tan, Alexander Karan, Dolores Albarracin

Research Collection School of Social Sciences

Although humans are intuitive dualists, little is known about whether they hold lay beliefs about the origins or sources of their intuitive perceptions of what is physical and what is mental. Drawing on theories of the sources of phenomenological experiences, we examined if people hold beliefs about the internal and social origins of judments that their experiences are physical or mental. In Study 1, participants provided physical or mental judgments about a range of personal experiences, and reported relying on both internal (i.e., examining own body and thoughts) and social (i.e., observing others) sources as information for their judgments. To …


A Conditional Linear Combination Test With Many Weak Instruments, Dennis Lim, Wenjie Wang, Yichong Zhang Jan 2024

A Conditional Linear Combination Test With Many Weak Instruments, Dennis Lim, Wenjie Wang, Yichong Zhang

Research Collection School Of Economics

We consider a linear combination of jackknife Anderson-Rubin (AR) and orthogonalized Lagrangian multiplier (LM) tests for inference in IV regressions with many weak instruments and heteroskedasticity. We choose the weight in the linear combination based on a decision-theoretic rule that is adaptive to the identification strength. Under both weak and strong identifications, the proposed linear combination test controls asymptotic size and is admissible. Under strong identification, we further show that our linear combination test is the uniformly most powerful test against local alternatives among all tests that are constructed based on the jackknife AR and LM tests only and invariant …


Optimal Nonparametric Range-Based Volatility Estimation, Tim Bollerslev, Jia Li, Qiyuan Li Jan 2024

Optimal Nonparametric Range-Based Volatility Estimation, Tim Bollerslev, Jia Li, Qiyuan Li

Research Collection School Of Economics

We present a general framework for optimal nonparametric spot volatility estimation based on intraday range data, comprised of the first, highest, lowest, and last price over a given time-interval. We rely on a decision-theoretic approach together with a coupling-type argument to directly tailor the form of the nonparametric estimator to the specific volatility measure of interest and relevant loss function. The resulting new optimal estimators offer substantial efficiency gains compared to existing commonly used range-based procedures.

Research Collection Yong Pung How School Of Law

In the recent Singapore High Court case of Bhoomatidevi d/o Kishinchand Chugani Mrs Kavita Gope Mirwani v Nantakumar s/o v Ramachandra and another [2023] SGHC 37, the claimant argued, inter alia, that evidence of a prior contract between the first defendant and a third party should be admitted to prove that the defendant had entered into a loan agreement with her in his personal capacity. Justice Lee Seiu Kin dismissed her claim, applying s. 14 of the Evidence Act.


The Geoeconomics Of Belt And Road Disputes: A Case Study On The China-Pakistan Economic Corridor, Mark Mclaughlin Jan 2024

The Geoeconomics Of Belt And Road Disputes: A Case Study On The China-Pakistan Economic Corridor, Mark Mclaughlin

Research Collection Yong Pung How School Of Law

This article argues that the dovetailing economic, geopolitical, and security interests that underpin the Belt and Road Initiative demands a dispute resolution mechanism that focuses on broader interests and legal rights. Using the China-Pakistan Economic Corridor (CPEC) as a case study, it identifies the conditions in which Chinese investors could have initiated an investment arbitration but did not. This can be explained by the rights-based orientation of investment treaties failing to reflect the interests of multi-project initiatives. Instead, alternative methods of home state intervention, such as state-funded political risk insurance, are used to protect investors. In other words, the political …

The management and control of power, and, in particular, the endeavour to strike the appropriate balance between affording governments the ability to act swiftly and decisively in the public interest while providing for adequate safeguards against governmental excess, is an intensely difficult undertaking. There is no one model that is correct for all times and all places.


Investigating Inland Waterway Transport Through A Sustainable Development Perspective: A Case Study Of Magdalena River (Colombia), Natalia Calderón-Rivera Jan 2024

Investigating Inland Waterway Transport Through A Sustainable Development Perspective: A Case Study Of Magdalena River (Colombia), Natalia Calderón-Rivera

World Maritime University Ph.D. Dissertations

The development of transport systems significantly influences economies, growth, and welfare of populations. However, these systems can have negative consequences, such as water and air pollution, traffic congestion, noise, and biodiversity loss. To address these challenges, it is essential to implement strategies that mitigate negative effects while improving the environmental, social, and economic conditions of the population. In this regard, inland water transport (IWT) is globally recognized as a more sustainable transport alternative due to its high cargo load capacities and comparatively lower environmental and social impacts. In Colombia, the Magdalena River – the country’s most important river basin – …

Training The Concept Of Innovate In Dolphins (Tursiops Truncatus) Is Both Creative And Cognitively Stimulating, Deirdre Yeater, Kathleen M. Dudzinski, Dawn Melzer, Andrew R. Magee, Michaela Robinett, Gonzalo Guerra, Kimberly Salazar, Terri Bolton, Heather Manitzas Hill

Psychology Faculty Publications

Creative or novel behaviors in bottlenose dolphins (Tursiops truncatus) can be indicators of flexible thinking and problem solving. Over 50 years ago, two rough-tooth dolphins demonstrated creative novel behaviors acquired through reinforcement training in human care. Since this novel training, a variety of species have been trained to respond to this conceptual cue. The current study assessed the creativity of 12 bottlenose dolphins (5 females, 7 males) housed at the Roatan Institute for Marine Sciences (RIMS) in Roatan, Honduras. Individual differences were found across four constructs measured for creativity: fluency, flexibility, elaboration, and originality. Variability in performance occurred across test …

The Simplified Additional Funds Needed Equation And Its Implications Jan 2024

The Simplified Additional Funds Needed Equation And Its Implications

Journal of Economics and Finance Education

As part of the corporate financial planning process, a firm must quantify the external funds required to achieve a specified growth rate. The additional funds needed (AFN) equation purportedly provides managers with a simple, first-cut way to do so. However, in its traditional specification, the AFN estimate appears to ignore financial feedback effects, potentially undermining its usefulness. This paper restates and simplifies the AFN equation. The new specification reveals that the estimated AFN is not distorted by financial feedback effects and can be used in its unadjusted form as an initial estimate of a firm’s financing needs.


Does Learning Economics Make You Less Susceptible To The Sunk Cost Fallacy? Jan 2024

Does Learning Economics Make You Less Susceptible To The Sunk Cost Fallacy?

Journal of Economics and Finance Education

The sunk cost fallacy is typically covered in introductory economics courses. It is among the most important biases that influence decision making. Ronayne et al. (2021a,b) find evidence of behavior consistent with the sunk cost effect and utilize eight questions that measure individuals’ susceptibility to the sunk cost fallacy. We extend their research by examining whether a “pop culture” teaching intervention in principles of microeconomics lowers students’ predisposition to the fallacy. We find that students become -14.95% less susceptible to the sunk cost fallacy after learning about it. We also observe that students who have taken economics previously exhibit lower …

The Essence Of The Image Of The Fool In The Context Of The Orthodox Teachings In Eastern Europe, Olga Polumysna, Valeriy Bulatov

Occasional Papers on Religion in Eastern Europe

The article explores aspects of the image of the holy fool in the context of Orthodox teaching in Eastern Europe. The phenomenon of people who are called holy fools in the thinking and teaching of the Orthodox religious tradition is a controversial issue and still causes conflicting opinions, because the actions of people called holy fools are difficult to understand both for simple observers and for Orthodox researchers. The contrast of opinions in the formation of the holy fool's gestalt is of particular interest to this study. Is the life of holy fools directly connected with sacred life and Orthodox …


Search For Resonance: The Latvian Evangelical Lutheran Church’S Quest For Relevance And Resonance Amidst The Complexity Of Contemporary Societal Discourse, Jānis Meļņikovs Jan 2024

Search For Resonance: The Latvian Evangelical Lutheran Church’S Quest For Relevance And Resonance Amidst The Complexity Of Contemporary Societal Discourse, Jānis Meļņikovs

Occasional Papers on Religion in Eastern Europe

This investigation examines the Latvian Evangelical Lutheran Church's role in Latvia's political debates, uncovering diverse opinions within the church on its public policy influence. Despite some members' active opposition and others' reluctance to engage in polarizing topics, the church steadfastly positions itself as a moral arbiter in society. Applying Hartmut Rosa's theories on public discourse and resonance, the study proposes the church as a place for deep, meaningful engagement with faith and society, where resonant experiences can foster individual and community well-being. Analysis of interviews illustrates the church's struggle to maintain its values in a modern, secular world, with individual …
