Prevalence and indoor environment risk factors of parent-reported food allergy symptoms among preschool children in Haikou City, China: A cross-sectional survey
Objective To understand the prevalence of parent-reported food allergy symptoms among preschool children in Haikou City and investigate indoor environmental risk factors for it. Methods A cross-sectional survey was conducted with 3,049 preschool children across eight kindergartens in Haikou City from December 2020 to January 2021. The survey aimed to analyze the influence of indoor environmental factors on parent-reported food allergy symptoms in…
Who benefits when AI summarizes? Evidence from a natural experiment on digital inequality between macro and micro creators
Purpose The widespread adoption of Artificial Intelligence-Generated Summary (AIGS) is reshaping how the user accesses and evaluates digital content. By automatically condensing information, AIGS enhances efficiency and facilitates user decision-making, but raises concerns about digital inequality among content creators. This study examines how AIGS affects such inequality between macro and micro creators. Design/methodology/approach Using a natu…

Reconstruction of 3D Information of Buildings from Single-View Images Based on Shadow Information
Accurate building geometry information is crucial for urban planning in constrained spaces, fueling the growing demand for large-scale, high-precision 3D city modeling. Traditional methods like oblique photogrammetry and LiDAR prove time consuming and expensive for low-cost 3D reconstruction of expansive urban scenes. Addressing this challenge, our study proposes a novel approach to leveraging single-view remote sensing images. By integrating sha…
Quantitative Study on American Covid-19 Epidemic Predictions and Scenario Simulations
The COVID-19 pandemic has had a profound impact on people’s lives, making accurate prediction of epidemic trends a central focus in COVID-19 research. This study innovatively utilizes a spatiotemporal heterogeneity analysis (GTNNWR) model to predict COVID-19 deaths, simulate pandemic prevention scenarios, and quantitatively assess their preventive effects. The results show that the GTNNWR model exhibits superior predictive capacity to the convent…
Perception bias, social embedding and consumer willingness to pay for chilled pork packaging: Empirical analysis based on multiple experiments
Purpose The paper proposes a research method to verify the perception bias of consumers on the freshness preservation effects of vacuum packaging (VP) and modified atmosphere packaging (MAP) chilled pork packages, the influence of “sensory experience” on correcting consumers' perception bias of packaging performance and willingness-to-pay (WTP) enhancement channels. Design/methodology/approach Using data from 458 and 188 participants who complete…
Effects of Climate Change on Corn Yields: Spatiotemporal Evidence from Geographically and Temporally Weighted Regression Model
Food security has been one of the greatest global concerns facing the current complicated situation. Among these, the impact of climate change on agricultural production is dynamic over time and space, making it a major challenge to food security. Taking the U.S. Corn Belt as an example, we introduce a geographically and temporally weighted regression (GTWR) model that can handle both temporal and spatial non-stationarity in the relationship betw…
Limited Role of Rhamnolipids on Cadmium Resistance for an Endogenous-Secretion Bacterium
Rhamnolipids, a type of biosurfactant, represent a potential strategy for both enhancing organismic resistance and in situ remediation of heavy metals contaminations. In-depth study of the mechanism of rhamnolipids synthesis in response to heavy metals stress, is indispensable for a wide use of biosurfactant-secreting microbes in bioremediation. In this study, we employed the wild-type and the rhlAB deficient strain (Δ rhlAB ) of Pseudomonas aeru…
A GloVe-Based POI Type Embedding Model for Extracting and Identifying Urban Functional Regions
Points-of-interest (POIs) are an important carriers of location text information in smart cities and have been widely used to extract and identify urban functional regions. However, it is difficult to model the relationship between POIs and urban functional types using existing methods due to insufficient POIs information mining. In this study, we propose a Global Vectors (GloVe)-based, POI type embedding model (GPTEM) to extract and identify urb…
Using Geographically Weighted Regression to Study the Seasonal Influence of Potential Risk Factors on the Incidence of HFMD on the Chinese Mainland
Hand, foot, and mouth disease (HFMD) is an epidemic infectious disease in China. Its incidence is affected by a variety of natural environmental and socioeconomic factors, and its transmission has strong seasonal and spatial heterogeneity. To quantify the spatial relationship between the incidence of HFMD (I-HFMD) and eight potential risk factors (temperature, humidity, precipitation, wind speed, air pressure, altitude, child population density, …

Engaging with globalisation: Chinese perspectives
China’s reform and opening-up process has coincided with the expansion of globalisation. Many people have expressed the belief that China has been the biggest winner in globalisation, and some of them even believe that the country has begun to take initiatives in globalisation instead of merely being affected by it. This article reviews the foundations of China’s engagement with globalisation, and shows how Chinese scholars have approached the st…
The Collection of Early Texts and the Establishment of Databases for Chinese Nationality Medicines
National and local projects to systematize ethnic or “nationality” medical systems are well underway in many parts of China. With colleagues in the China Academy of Chinese Medical Sciences, and in collaboration with scholars associated with various nationalities, we have undertaken the task of editing a catalog of early texts in Chinese minority nationality medicine. We argue that it is both more efficient and more intellectually coherent for th…
RTsa in the Tibetan Manuscripts from Dunhuang
In the earliest extant specialist medical work sMan dpyad zla ba’i rgyal po (The Medical Investigation of the Lunar King , early 8th century CE) and the classical work of Tibetan medicine, rGyud bzhi (The Four Medical Tantras , generally dated by scholars to the 12th century CE), there are records of rtsa in its meaning of 'pulse taking'. The concept of rtsa in Tibetan medicine, as the Chinese mai 脈, eventually came to combine notions of 'the ves…
