There is sample evidence that work conditions affect employees' well-being. Losses in work quality (increased job stressors and reduced job resources) are thought to be related to deteriorations in well-being, whereas gains in work quality (reduced job stressors and increased job resources) are believed to improve well-being. The way most previous studies tested linkages between work conditions and well-being assumes that as much as a loss in work quality harms well-being, a gain in work quality results in an improvement. However, Hobfoll's conservation of resources (COR) theory argues that losses have a stronger impact than gains do. To date, this assumption still awaits a thorough empirical test. Using data from three longitudinal studies (s = 10,756, 579, and 2,441), we investigated the effects of changes in work conditions on well-being. Changes in work conditions were related to changes in well-being, and these relationships were weaker with longer time lags. Moreover, in line with COR theory, our analyses suggested that the effect of a loss in work quality was generally stronger than the effect of a gain. Interestingly, however, we found a more consistent pattern for the effect of certain stressors (e.g., social stressors) than others (e.g., workload). By testing a central principle of COR theory, this research advances theoretical understanding of how work affects well-being. Furthermore, by revealing that previous studies may have underestimated the detrimental effects of deteriorating work conditions and overestimated the positive effects of improved work conditions on well-being, this research also has implications for organizational interventions.

For tolerant containment control of multi-agent systems, considering the challenges in modeling and the impact of actuator faults on system security and reliability, a finite index dynamic event-triggered policy iteration algorithm is proposed. This algorithm only requires input and output data, without relying on system models, and simultaneously considers the faults and energy consumption issues to improve the system reliability and save energy consumption. The conditions are provided to demonstrate the convergence and optimality of the algorithm, including a convergence speed, that is, the number of iterations required for convergence is finite.

As artificial intelligence advances and demand for cost-effective equipment maintenance in various fields increases, it is worth insightful research on utilizing robots embedded with sound source localization (SSL) technology for condition monitoring. Combining the two techniques has significant advantages, which are conducive to further classifying and tracking abnormal sources, thereby enhancing system performance at a lower cost. The paper provides an overview of current acoustic-based robotic techniques for condition monitoring, highlights the common SSL methods, and finds that localization performance heavily depends on signal quality.

In recent decades, microplastics (MPs) have emerged as one of the biggest environmental challenges in aquatic environments. Ingestion and toxicity of MPs in seawater (SW) and freshwater (FW) fish have been studied extensively both in field and laboratory settings. However, the basic mechanism of how fish deal with MPs in SW and FW remains unclear, although physiological conditions of fish differ significantly in the two environments.

We present the results of a 1-year study that quantified salt levels in stormwater, soils, and plant tissues from 14 stormwater detention basins across Northern VA in an above-average snow year. We characterize (1) the level of salt stress plants experience, (2) the extent to which current plant communities feature salt tolerant species, and (3) the capacity of these species to phytoremediate soils and reduce the impacts of deicer and anti-icer use. Our results suggest that detention basin vegetation experience a range of salt stress levels that depend on drainage area type (roads: moderate to high > parking lots: low to moderate > pervious areas: none).

The macromolecular components of the seed coat, particularly lignin, play a critical role in regulating seed viability. In the maize-soybean intercropping (MSI) system, shading stress was reported to enhance the viability of soybean seeds. However, the specific role of seed coat lignin in this process remains poorly understood.
