Previous studies have suggested that Western constructs of academic motivation may operate in different ways in Asian contexts due to differences in the cultural environment. In the present study, the integrative effects of achievement goals, strategy orientations, and effort expenditure on achievement outcomes were examined among 1950 seventh-grade Chinese students in Hong Kong. Participants completed separate questionnaires for mathematics and English. Results for the two subjects were largely similar. There were significant positive relationships between mastery and performance goals, between cooperative and competitive orientations, as well as between understanding and memorizing strategies. Regression analyses further revealed that goals and strategies were highly predictive of effort expenditure, but only goals and effort significantly predicted achievement outcome, with strategies being barely significant. The need to further investigate how Chinese students reconcile the apparently antithetical orientations in learning as well as the effective strategies contributing to their learning is indicated.

This article presents a comprehensive examination of the combined catalytic conversion technology for nitrogen oxides (NOx) and volatile organic compounds (VOCs), which are the primary factors contributing to the formation of photochemical smog, ozone, and PM2.5. These pollutants present a significant threat to air quality and human health.

Low-color-temperature candlelight organic light-emitting diodes (OLEDs) offer a healthier lighting alternative by minimizing blue light exposure, which is known to disrupt circadian rhythms, suppress melatonin, and potentially harm the retina with prolonged use. In this study, we explore the integration of transition metal dichalcogenides (TMDs), specifically molybdenum disulfide (MoS) and tungsten disulfide (WS), into the hole injection layers (HILs) of OLEDs to enhance their performance. The TMDs, which are known for their superior carrier mobility, optical properties, and 2D layered structure, were doped at levels of 0%, 5%, 10%, and 15% in PEDOT:PSS-based HILs.

Understanding the evolution of low-carbon efficiency in urban built-up areas is essential for developing countries striving to meet sustainable development goals. However, the mechanisms driving low-carbon efficiency and the associated development pathways remain underexplored. This study applies the Global Data Envelopment Analysis (DEA) model, the Global Malmquist-Luenberger Index, and econometric models to evaluate low-carbon efficiency and its determinants across China's urban built-up areas from 2010 to 2022.

Chronic obstructive pulmonary disease (COPD) is a life-limiting condition and the third leading cause of death worldwide. People with COPD experience physical and psychological symptoms and functional limitations that impair their quality of life. Their caregivers face adverse clinical outcomes due to personal, social, and financial demands.
