Problematic smartphone use (PSU) has emerged as a pressing concern among college students, with cumulative ecological risk identified as a crucial yet enigmatic contributor. To unravel its underlying mechanisms, we devised and validated a model that delves into the mediating roles of performance and learning goal orientations, as well as the moderating influence of psychological resilience. Our investigation encompassed 2011 Chinese college students spanning from freshmen to seniors, aged 16 to 25, utilizing comprehensive scales to assess various constructs. The findings revealed that both performance and learning goal orientations serve as pivotal mediators in the relationship between cumulative ecological risk and PSU. Furthermore, psychological resilience was found to moderate not only the direct link between cumulative ecological risk and PSU but also the indirect pathway through learning goal orientation. These insights underscore the practical significance of fostering healthy achievement goals and enhancing psychological resilience among college students, thereby mitigating the prevalence of PSU.

Peatlands are key ecosystems for global climate regulation because they provide the most efficient carbon sink on the planet. Despite this, they have been widely degraded by various anthropogenic disturbances, causing imbalances in their ecological functioning. A more recent type of disturbance corresponds to the commercial extraction of Sphagnum mosses, which has been carried out in temperate peatlands distributed in Australasia and Patagonia.

Background: Mental fatigue (MF) is a psychobiological state that could negatively impact physical and cognitive performance, although the extent of this impact remains controversial. While laboratory studies have provided valuable insights into the acute effects of MF, their ecological validity in real-world sport settings remains limited. Recent research indicates that MF can naturally arise during sport activities, leading to chronic effects on endurance and perceptual-cognitive skills.

In this study, the contamination, ecological and human health risks as well as source apportionment of As, Cd, Co, Cr, Cu, Mn, Ni, Pb, Zn, and V in street dusts of different land-uses in Kermanshah, Iran were investigated. A total of 192 dust samples were taken from 16 sites and were analyzed for their elemental contents using ICP-OES. The computed mean values for the geo-accumulation index (I-geo) and the pollution index (PI) ranged from - 6.

Soil salinization becomes serious under climate change and human activities. Although the residue decomposition contributes lots to soil carbon storage and fertility, the decomposition process and microbial mechanisms on saline-alkali soils are still vague facing climate change. We measured the mass loss of residue (0, 4, 8, 15, 30, 60 and 90 days), CO emission (every two days), and the microbial community structure (0, 4, 15 and 90 days) by using the litter bag method, gas chromatography and high-throughput sequencing technology during the residue decomposition (90 days) in a saline-alkali soil from the Tarim River Basin, China under various temperatures (15 °C, 25 °C, 35 °C) and soil moisture levels (20%, 40%, 60% water holding capacity).
