Introduction To The Special Issue: Cities And Economic Development, Shihe Fu, Junfu Zhang

Economics

To a great extent, economic development is urban development. As economies grow, people and firms cluster in cities to take advantage of agglomeration economies, better infrastructure, access to markets and labor, and consumption amenities. Urbanization not only drives productivity gains and enhances consumer welfare but also introduces challenges such as housing affordability, traffic congestion, pollution, and inequality. Understanding these dynamics is essential for promoting efficiency and sustainable development. The evolution of cities is therefore not only a reflection of economic progress but also a key driver of it.

High Frequency Factor Analysis With Partially Observable Factors, Dachuan Chen, Wenqi Lu, Siyu Xie

Research Collection School Of Economics

This paper considers a novel factor structure – Partially Observable Factor Model – where both observable factors and latent factors exist in the model simultaneously. Such factor structure can make sure both interpretability and goodness-of-fit at the same time. Necessary estimation methodologies for this partially observable factor model are developed in this paper for the high frequency data. The proposed estimation methodology is robust to jumps, microstructure noise and asynchronous observation times simultaneously.When the observable factors are exogenous, we provide the estimation theory for the integrated eigenvalues of the residual covariance matrix, which including the bias-corrected estimator, central limit theorem …

Political Ecologies Of Storage For The 21st Century, Sayd Randle, Matthew Archer

Research Collection College of Integrative Studies

New resource storage arrangements are proliferating rapidly both in terms of physical infrastructures-for the storage of things like "clean" energy, nuclear waste, carbon dioxide, fresh water, and data-and as part of a set of discursive moves that reinforce a vision of a near future world in which problems of climate change mitigation and adaptation in particular (but also issues like energy security, water security, industry growth, etc.) are solved through eco-modernist techno-fixes. This Symposium sketches the contours of a framework we term political ecologies of storage. In doing so, we treat storage as both a potent imaginary and a concrete …

Assessment Of Spatial Autocorrelation And Scalability In Fine-Scale Wildfire Random Forest Prediction Models, Madeleine Pascolini-Campbell, Joshua B. Fisher, Kerry Cawse-Nicholson, Christine M. Lee, Natasha Stavros

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Wildfire prediction models that can be applied across diverse regions at fine scales (<  100 m) are critical for wildfire management. Remote sensing offers a path forward by providing heterogeneous and dynamic measurements of fuel load, type, and flammability. Machine learning methods such as random forests provide an empirical framework that are high-accuracy, computationally efficient, interpretable and able to model complex ecological relationships. Here we use high resolution (70 m, every 3–5 days) remote sensing observations of evapotranspiration and evaporative stress index, which represent plant water stress, from Ecosystem Spaceborne Thermal Radiometer on Space Station (ECOSTRESS), as well as topography and weather data, to predict burn severity and occurrence for 8 large wildfires that burned 3715 km² from 2021 and 2022 in New Mexico, USA. These fires ranged from low to high burn intensity, and covered a diverse range of ecoregions (deserts, grasslands, forests), plant species, and topographies. We used a single model to predict the burn severity of all wildfires one week before occurrence. The prediction accuracy was greatest when using all predictors (ECOSTRESS, weather, topography) (R² = 0.77). We assessed the role of spatial autocorrelation in driving model performance by: (1) increasing the sample spacing of our dataset, (2) …

Multi-Period Portfolio Allocation: A One-Shot Stochastic Optimization Approach, Peng Liu, Chyng Wen Tee, Xiaofei Xu

Research Collection Lee Kong Chian School Of Business

Multi-period portfolio optimization is a central problem in finance, yet it is computationally intractable for traditional dynamic programming methods due to the curse of dimensionality. This paper develops a tractable and theoretically grounded 'one-shot' stochastic optimization framework that recasts the sequential decision problem into a single, high-dimensional optimization task. Our approach models the predictive distribution of factor returns using Gaussian Processes (GPs), allowing it to capture complex, non-linear market dynamics. We make three primary contributions. First, for the special case of a linear GP kernel, we derive an analytical solution for the optimal portfolio path, providing a clear economic interpretation …

The Dynamics Of Word-Of-Mouth Marketing: An Agent-Based Modeling Approach To Message Credibility And Consumer Engagement, Ali Nasirzonouzi, Carlos Gershenson

Northeast Journal of Complex Systems (NEJCS)

Word-of-mouth (WOM) marketing is a critical factor in the dissemination of information and adoption of products in social networks. This paper investigates the impact of two important factors message credibility and consumer engagement on WOM adoption dynamics using agent-based modeling (ABM). This study proposes a simple qualitative model to investigate how these factors influence adoption rates through both broadcast communication and peer-to-peer influence by simulating interactions on a spatially clustered network.

The findings show that increased message credibility significantly boosts adoption, achieving a balance between broadcast and social mechanisms. Also, consumer engagement primarily affects the adoption mechanism, shifting the effect …

Natural Language Processing Pipeline For Assessment Data: An R-Based Tutorial, Constanza Mardones-Segovia, Shiyu Wang, Allan S. Cohen

Chinese/English Journal of Educational Measurement and Evaluation | 教育测量与评估双语期刊

Natural language processing (NLP) has become an increasingly popular approach for analyzing textual responses in educational assessments. An important part of NLP involves cleaning and structuring examinees' written responses to create input data that conserves the syntax, semantics, and pragmatics of the words, thereby enabling the extraction of these features. This paper provides foundational knowledge on the steps needed for using NLP in educational measurement tasks, guiding researchers and practitioners through text preprocessing, feature extraction, and analyzing textual data from constructed response items. Additionally, an R-based example using Latent Dirichlet Allocation is provided, illustrating each step in the pipeline.

Digital Infrastructure For The Regenerative Movement: A Case Study Of The Mycelium Learning Network, Abigail Karparis

Journal of Nonprofit Innovation

The regenerative movement is gaining momentum worldwide, driven by communities working to restore ecological and social systems through place-based, culturally rooted action. Yet many of the groups leading this work, especially in the Global South or in hyper-local contexts, remain digitally invisible due to structural barriers, including limited access to appropriate technology, funding constraints, and misalignment between available tools and local values. Conventional digital infrastructures often exclude or marginalize these efforts, leaving regenerative practitioners disconnected from each other and from potential sources of support.

This article explores these challenges and presents a case study response: the co-creation of accessible, relational …

Non-Discriminatory Personalized Pricing, Philipp Strack, Kai Hao Yang

Cowles Foundation Discussion Papers

A monopolist offers personalized prices to consumers with unit demand. Consumers differ in their values, costs, and \emph{protected characteristics}---such as race or gender. The seller is subject to a non-discrimination constraint: consumers with the same cost, but different protected characteristics must face identical price distributions. Such regulations are present in markets like credit or insurance. We characterize the optimal pricing rule. Under this rule, surplus accrues to both protected groups, but only to those with intermediate values. Strengthening the constraint to cover transaction prices redistributes surplus, harming the low-value group and benefiting the high-value group. Meanwhile, prohibiting the use of …

Exploration Of Adventure-Based Counseling And Its Impact On The Self-Concept Of At-Risk Youth, Kendall Kern, Mary Bess Pannel, Todd Davis, Thales Barbosa

Journal of Academic Underperformance

Background: Integrating experiential therapy techniques with physical activity and nature improves aspects of self-concept: social connectedness, resilience, and healthy coping skills in the short-term for at-risk, underperforming youth (Kraft & Cornelius-White, 2020). Kraft and Cornelius-White (2020) found that wilderness therapy counselors that taught communication skills and prioritized “group cohesion in group therapy” led to positive “changes to self-concept” (p. 350-351). Purpose: The researchers hypothesize that community-based adventure therapy will have a positive impact on the self-concept in at-risk, rural youth. Methodology/Approach: The researchers utilized a quasi-experimental model to assess the impact of adventure therapy on rural at-risk youth (N~6) after …

Quantifying Adversary Military Forces’ Susceptibility To Cognitive Attacks, Bonnie Rushing, Cole Nelson, Shouhuai Xu, Christofer “Raven” O’Keefe, Olga Karpoyan

Military Cyber Affairs

This paper introduces a method to quantify international populations’ susceptibility to cyber cognitive attacks using press freedom and media trust metrics. We present the Cognitive Influence Calculator, a tool that estimates susceptibility (𝑆) based on Press Freedom Scores (PFS) and media trust levels. Findings show that while authoritarian regimes are harder to reach, successful cognitive attacks have greater impacts due to higher trust in state-controlled narratives. Using U.S. wargaming data and international trust metrics, we compute susceptibility scores for the U.S., Russia, China, Iran, and North Korea. Results show an inverse relationship between PFS and media susceptibility, with local/allied …

A “Teaching As Emergent Learning” Approach To Teaching Deep Creativity, Steven Greenstein, Iain Kerr, Emily Olson

LASER Journal

Creativity is the process by which a change that is new and different emerges. We call it deep when it yields novel forms of both quantitative and qualitative change. If we are to take on the most pressing and persistent challenges to our social, global, and planetary well-being, we need novel approaches of a qualitatively different kind than those that have failed to bring about radical change in the past. In other words, we need deep creativity. The paradox at the heart of ``ideation-first" approaches to creative practice (e.g., brainstorming or ideating) is that if creativity aims to produce outcomes …
