Hourly PM2.5 Forecasting for Sustainable Urban Air Quality Management Through Multiresolution Learning and Environmental Context

Reliable hourly forecasts of fine particulate matter (PM2.5) can help cities anticipate deteriorating air quality and prepare measures to limit exposure. A central modeling challenge is to combine rapid pollution fluctuations with meteorological and ecological observations that a...

Association of Caregiver Mental Health and a Childhood Parenting Intervention in China

OBJECTIVES This study examines whether and how caregiver mental health symptoms influence the impacts of a center-based parenting intervention on child development. METHODS We conducted a clustered randomized controlled trial across 100 rural villages in China between 2016 and 20...

Purpose In today’s rapidly evolving business environment, firms face increasing pressure to adopt sustainable practices, with the circular economy (CE) model emerging as a transformative pathway toward environmental and economic resilience. This study aims to investigate the role...

Fixed or flexible: How product formats affect consumer redemption behavior for live-streamed food and beverage (F&B) products

With the rapid growth of live-streaming e-commerce in the food and beverage industry, low redemption rates despite high sales volumes have become a critical challenge for merchants. This research investigates how product formats and familiarity affect consumer redemption behavior...

Spot‐Based Basis and Basis Momentum in Commodity Futures Markets

ABSTRACT This paper revisits two widely studied predictors of commodity futures returns, basis and basis momentum, whose conventional measures using first‐nearby futures as proxies for spot prices may limit their ability to capture fundamental spot‐market risks. Motivated by this...

Facilitating residents’ storytelling in tourism communities: Communication infrastructure and acculturation

Storytelling has become an important means of destination branding, with residents as key creators and disseminators of local narratives. However, the structural and cultural conditions that enable residents' storytelling behavior remain insufficiently understood. Drawing on Comm...

Green energy transition and energy efficiency in Türkiye: The roles of industrial productivity and fossil fuel inefficiency

This study investigates the determinants of energy efficiency effectiveness in Türkiye within the context of green energy transition and sustainable development goals over the period 1990–2024. Despite the growing importance of sustainable energy transformation, limited attention...

Teachers' AI use and student learning outcomes in higher education: The roles of learning engagement and teacher AI literacy

Purpose As generative artificial intelligence (AI) becomes increasingly integrated into higher education, teachers are playing a central role in transforming AI technologies into educational value. However, empirical evidence regarding whether and how teachers' AI use improves st...

Natural and Health Risk, Livelihood Resilience, and Relative Poverty Depth

Reducing relative poverty among rural households is important for inclusive and sustainable development. Using balanced panel data from the China Family Panel Studies (CFPS) for 2016–2022, this study draws on the Sustainable Livelihoods Framework and resilience theory to examine...

Environmental enforcement federalism

Abstract This paper studies whether environmental enforcement powers should be assigned to central or regional authorities. We develop a two-stage model in which authorities choose inspection intensities under imperfect monitoring, then firms determine emissions and compliance be...

Editor’s introduction

Kingdom, Vietnam.Collectively, these studies employ diverse theoretical perspectives and advanced analytical methods to examine the evolving dynamics of digital and traditional financial markets, energy and commodity markets, and the growing interactions between finance, technolo...

Testing Alphas in Linear Factor Models: A Portfolio Approach

This paper develops a test for evaluating linear factor models in high-dimensional settings. The proposed Maximum Random Sparse Portfolio (MRSP) test generates L random sparse portfolios, each obtained through K random draws, and then selects the hardest-to-price portfolio to ass...

Semigroup well-posedness and exponential decay of a viscoelastic bilateral contact model with Tresca’s law and infinite memory

In this article, we consider a dynamic contact for viscoelastic materials. The contact is bilateral, and the friction is modeled with Tresca’s friction law which provides a clear physical description of dry friction at the contact interface. The material is assumed to follow a no...

Dynamic capacity investment and debt financing

It is common for companies to conduct multiple capacity expansions in a growing market. In this article, we study how firms make optimal multi-stage investment timing, scale, and capital structure decisions in the context of multiple growth options and existing assets. We show th...

Rethinking Mathematical Knowledge: A Nativist Approach

This paper develops a nativist approach to mathematical knowledge as an alternative account within the philosophy of mathematics. Rather than beginning with the ontological status of mathematical objects, it argues that any satisfactory account of mathematical knowledge should ad...

Barriers and facilitators to physical activity promotion by healthcare professionals: an umbrella review

Abstract Background Physical inactivity is consistently associated with the incidence of chronic diseases. The clinical environment may be an ideal setting to promote physical activity (PA). To date, substantial efforts have been made by multiple institutions to encourage PA prom...

Performance of multi-strategy optimized mayfly optimization algorithm for location selection of university reimbursement form submission terminals

Abstract The Mayfly Optimization Algorithm(MOA) suffers from inherent drawbacks, such as susceptibility to local optima and slow convergence speed. In this study, an improved mayfly algorithm integrated with multiple strategies is proposed. Firstly, a Logistic chaotic map is adop...

Carbon Pricing and Corporate Investment Responses: Evidence from China’s Emissions Trading System

Carbon pricing has emerged as a central policy tool for addressing climate change and advancing corporate environmental responsibility, yet its impact on firm-level investment and capital allocation remains insufficiently understood, particularly in emerging economies. This study...

Can the mitigation of water constraints promote regional entrepreneurial activity? Evidence from China

Traditional entrepreneurial choice models typically consider only entrepreneurial talent and capital inputs, neglecting natural resource endowments. The debate over whether the scarcity of natural resources affects regional entrepreneurial activity remains inconclusive. In countr...

Leave-one-out analysis for nonconvex robust matrix completion with general thresholding functions

We study the problem of robust matrix completion (RMC), where the partially observed entries of an underlying low-rank matrix is corrupted by sparse noise. Existing analysis of the non-convex methods for this problem either requires the explicit but empirically redundant regulari...
