Fighting For Time: Spillover and Crossover Effects of Long Work Hours Among Dual-Earner Couples

Drawing upon the spillover-crossover model, this study examined the extent to which one\u27s work time demands spilled over to the family domain, and crossed over to his or her spouse, utilizing data of 365 dual-earner couples from the 500 Family Study. The results of the distinguishable actor-partner interdependence model indicated that there was gender symmetry in the spillover processes such that the effects of work hours were identical between men and women. Further, although there was more bi-directional crossover between partners within couples, we observed some unidirectional crossover from husbands to wives. Specifically, husbands only increased their contribution to domestic work in response to wives\u27 work fatigue, whereas wives increased their contribution to domestic work in response to husbands\u27 work fatigue and high workloads. Finally, husbands\u27 housework hours negatively related to wives\u27 marital satisfaction and positively related to wives\u27 depression, whereas wives\u27 housework hours negatively related to husbands\u27 marital satisfaction and depression. These findings have practical implications for improving the work-family balance, health, and well-being of dual-earner couples

Age Differences in Stress and Coping: Problem-Focused Strategies Mediate the Relationship between Age and Positive Affect

The present study examined the different types of stressors experienced by adults of different ages, their coping strategies, and positive/negative affect. A mediation hypothesis of coping strategies was tested on the relationships between age and positive/negative affect. One-hundred and ninety-six community-dwelling adults (age range 18-89 years old) reported the most stressful situation they experienced in the past month and coping strategies. Levels of positive and negative affect in the past month were also measured. Content analysis revealed age differences in different types of stressors adults reported. Three types of coping strategies were found: problem-focused, positive emotion-focused, and negative emotion-focused coping. Older adults were less likely than younger adults to use problem-focused coping and reported lower levels of positive affect. Path analysis supported the mediation hypothesis, showing that problem-focused coping mediated the relationship between age and positive affect. Implications are discussed on the importance of promoting problem-focused coping among older adults

Effectiveness of Dynamic Compaction on Liquefied Foundation in Highway Practice

In this paper, the in-situ dynamic compaction tests with different values of single-drop-compaction energy are performed on a liquefiable ground encountered in highway engineering practice. Excess pore pressure, total surface settlement and lateral deformation under dynamic compaction impact are measured and analyzed at different conditions, such as single drop-compaction-energy, drop numbers, depth of soil layer etc. The standard penetration test (SPT) is used for investigating the compaction effectiveness. The investigation results indicate dynamic compaction technique is an effective way for improving liquefiable ground in highway engineering practice. Relatively small single-drop-compaction energy and relatively more drop numbers should be adopted for improving natural sedimentary liquefiable ground with dynamic compaction. The in-situ dynamic compaction tests show that the effective effect range by dynamic compaction impact depends on the single-drop-compaction energy. It is also found that the measured maximum lateral deformation has a good linear relationship with the total vertical surface settlement

Angle dependent field-driven reorientation transitions in uniaxial antiferromagnet MnBi2_2Te4_4 single crystal

MnBi$_2$Te$_4$, a two-dimensional magnetic topological insulator with a uniaxial antiferromagnetic structure, is an ideal platform to realize quantum anomalous Hall effect. However, the strength of magnetic interactions is not clear yet. We performed systematic studies on the magnetization and angle dependent magnetotransport of MnBi$_2$Te$_4$ single crystal. The results show that the direction of the magnetic field has significant effects on the critical field values and magnetic structure of this compound, which leads to different magnetotransport behaviors. The field-driven reorientation transitions can be utilized to estimate the AFM interlayer exchange interaction coupling and uniaxial magnetic anisotropy D. The obtained Hamiltonian can well explain the experimental data by Monte Carlo simulations. Our comprehensive studies on the field-driven magnetic transitions phenomenon in MnBi$_2$Te$_4$ provide a general approach for other topological systems with antiferromagnetism.Comment: 6 figure

Mechanistic modeling of marsh seedling establishment provides a positive outlook for coastal wetland restoration under global climate change

While many studies focus on the persistence of coastal wetlands under climate change, similar predictions are lacking for new wetland establishment, despite being critical to restoration. Recent experiments revealed that marsh seedling establishment is driven by a balance between physical disturbance of bed-level dynamics and seedling root stability. Using machine learning, we quantitatively translate such finding in a new biogeomorphic model to assess marsh establishment extent. This model was validated against multiyear observations of natural seedling-expansion events at typical sites in the Netherlands and China. Subsequently, synthetic modeling experiments underscored that seedling expansion was primarily determined by controllable local conditions (e.g., sediment supply, local wave height, and tidal flat bathymetry) rather than uncontrollable climate change factors (e.g., change in sea-level and global wave regime). Thus, science-based local management measures can facilitate coastal wetland restoration, despite global climate change, shedding hope for managing a variety of coastal ecosystems under similar stresses

Antecedents of older nurses\u27 intentions to continue working in the same organization after retirement

This study contributes to the literature on bridge employment by examining the relationships between job-related psychosocial factors (i.e., generativity opportunities, workplace incivility, and relational job crafting) and intentions to continue working in the same organization after retirement, as well as the underlying mechanism through work meaningfulness. Furthermore, the moderating role of individuals’ communion striving motivation was tested. A sample of 384 nurses 50 years old or above was recruited to test the hypothesized moderated mediation model. Results indicated that all the three examined job-related psychosocial factors (except generativity opportunities) were significantly related to older nurses’ intentions to continue working in the same organization after retirement. Work meaningfulness partially mediated the relationships between workplace incivility, relational job crafting, and older nurses’ intentions to continue working in the same organization after retirement. Work meaningfulness also fully mediated the relationship between generativity opportunities and older nurses’ intentions to continue working in the same organization after retirement. Finally, communion striving motivation enhanced the positive relationship between generativity opportunities and work meaningfulness and exaggerated the indirect relationship between generativity opportunities and older nurses’ intentions to continue working after retirement via work meaningfulness. Overall, findings suggest that in order to retain older nurses, organizations should lower workplace incivility, provide generativity opportunities, encourage relational job crafting, and cultivate work meaningfulness. Implications of these findings, as well as directions for future research, are discussed
