Geographically weighted quantile regression (GWQR) has been proposed as a spatial analytical technique to simultaneously explore two heterogeneities, one of spatial heterogeneity with respect to data relationships over space and one of response heterogeneity across different locations of the outcome distribution. However, one limitation of GWQR framework is that the existing inference procedures are established based on asymptotic approximation, which may suffer computation difficulties or yield incorrect estimates with finite samples. In this paper, we suggest a bootstrap approach to address this limitation. Our bootstrap enhancement is first validated by a simulation experiment and then illustrated with an empirical US mortality data. The results show that the bootstrap provides a practical alternative for inference in GWQR and enhances the utilization of GWQR.

The Effects of Polystyrene Microplastics and Copper Ion Co-Contamination on the Growth of Rice Seedlings.
Nanomaterials (Basel)
December 2024
State Key Laboratory of Environmental Criteria and Risk Assessment, State Environmental Protection Key Laboratory of Regional Eco-Process and Function Assessment, Chinese Research Academy of Environmental Sciences, Beijing 100012, China.
Microplastics (MPs) are emerging pollutants of global concern, while heavy metals such as copper ions (Cu) are longstanding environmental contaminants with well-documented toxicity. This study investigates the independent and combined effects of polystyrene microplastics (PS-MPs) and Cu on the physiological and biochemical responses of rice seedlings ( L.), a key staple crop.

Background: Reference intervals (RIs) are crucial for distinguishing healthy from sick individuals and vary across age groups. Hemoglobinopathies are common in Pakistan, making the quantification of hemoglobin variants essential for screening. Direct RIs are established by measuring values from a healthy reference population, whereas indirect RIs, use statistical analysis of routine lab data to estimate values, making it feasible in settings where direct data is unavailable.

College of Geography and Planning, Chengdu University of Technology, Chengdu, 610059, China.
The natural suitability of human settlements is greatly influenced by the distinct ecological environment and natural conditions of the plateau area, which are of great eco-environmental significance. 32 counties in China's Western Sichuan Plateau were chosen as the study's research subjects. The evaluation index system and weight of the natural suitability of human settlements were established, along with the obstacle degree model, using the analytical hierarchy process, the entropy method, and the integrated weight method.

In Southeast Guizhou, a region of China rich in ethnic diversity, the cultural landscapes of ethnic villages are increasingly vulnerable under the pressures of urbanization and tourism development. This study assesses the vulnerability of 43 ethnic villages in Leishan County using the Vulnerability Scoring Diagram (VSD) model, which evaluates exposure, sensitivity, and coping ability. Analyses using spatial autocorrelation and geographic weighted regression reveal distinct spatial patterns of vulnerability, with the northern region exhibiting higher vulnerability indices than the southern region.

Objectives: This systematic review aims to assess the available evidence on the prevention of type 2 diabetes mellitus (T2DM) among Middle Eastern (ME) populations residing in high-income countries (HICs). The review focuses on two key aspects: (1) evaluating the efficacy of interventions for improving health outcomes and (2) examining the barriers to and facilitators of the implementation and effectiveness of interventions.
Design: Systematic review.
