Effects of Land Use/Land Cover Changes on Carbon Storage in Terres‐Trial Ecosystems of the Mongolian Plateau
The carbon storage capacity of the Mongolian Plateau (MP) is easily ignored compared to other ecological services, due to its vast steppes and diverse arid and semi‐arid landscapes. However, the impact of Land Use/Land Cover (LULC) changes on carbon storage (CS) remains unclear, limiting climate‐adaptive land policies. This research combined with the PLUS and InVEST models to assess the dynamic characteristics of LULC and CS in the MP from 2000 t…
Fixations, regressions, and results
Introduction Educators need real time evidence of how students process pre class quiz items in flipped courses, not just whether answers are right or wrong. We examined whether two classroom feasible eye tracking metrics—fixation intensity (total dwell time) and regression rate (proportion of backward saccades)—provide interpretable, item level signals of cognitive engagement once surface text features are taken into account. Methods Thirty four …
Challenges and Coping Strategies in Transitioning From Caregiving to Widowhood
Ninety-one percent of surviving spouses in the U.S. cared for their spouses before they died. This review explores the challenges of the transition from caregiving to widowhood and different coping strategies used by widowed spousal caregivers. A systematic review of literature on the transition from caregiving to widowhood was conducted using four major academic search engines. Overall, 280 articles were identified, with 22 meeting the inclusion…
Effects of large-scale changes in environmental factors on the genesis of Arctic extreme cyclones
The Arctic cyclone is an active weather system in the Arctic, and the Arctic extreme cyclone (AEC) strongly influences polar weather. Thus, many studies have focused on the activity of AEC and its relationship with large-scale circulation in the Arctic. In this study, Arctic cyclones were detected using the ERA5 Reanalysis data from 1979 to 2020, and the AECs of cold and warm semesters were defined using the 5th percentile of sea level pressure. …
Cold season Arctic strong cyclones enhance Atlantification of the Arctic Ocean
In recent years, as the Arctic Ocean’s warming trend has accelerated, there has been increasing attention on the process of Atlantification in the Arctic Ocean. This study focused on the Arctic Atlantic inflow zone (AAZ) as its research area. Multi-source reanalysis data and in-situ Argo float data were utilized to detect Arctic strong cyclones (ASCs) in the AAZ and analyze the resulting changes in the upper ocean. The findings reveal that during…
Exposure, perceived risk, and psychological distress among general population during the Covid-19 lockdown in Wuhan, China
These findings conduce to identify the populations at higher risk of suffering psychological disturbance during the pandemic and are expected to inform the policymakers and mental health professionals to monitor and improve the perception of risk among the target population by appropriate interventions
Renovation of Informal Green Spaces in Old Urban Residential Communities in Chinese Cities and Related Public Perception Investigation
Existing large-scale urban green spaces in a low distribution density can hardly meet citizens’ diverse and growing needs for convenient access and sharing modes, especially to those living in old communities. Compared with formal green spaces, informal green space (IGS) is a new urban green infrastructure contributing to the city’s coconstruction, co-governance, and co-sharing. This study was conducted based on a typical old residential communit…
A Group-Based Walking Study to Enhance Physical Activity Among Older Adults
OBJECTIVES: The aim of this study was to explore social engagement and social comparisons as mechanisms to increase physical activity among older adults. METHODS: Participants (N = 60, mean age = 65.7) were randomly assigned to one of two conditions. Participants in the treatment condition used the application to track their daily walking steps and interact via text messages with their group members for 4 weeks. Participants in the control group …
Occupational Characteristics in the Outbreak of the Covid-19 Delta Variant in Nanjing, China
The risk of contracting COVID-19 varies by occupation. Clarifying the occupational disparity in the infection risk is crucial to the prevention and control of the epidemic in the workplace. In late July, some new cases of COVID-19 were confirmed among cleaners working in Lukou International Airport in Nanjing, China. The infected cases rapidly increased and spread to many domestic cities in the following days. The present study traces the brief r…
Personality change profiles and changes in cognition among middle-aged and older adults
Education and Cognition in Middle Age and Later Life
Physical and cognitive activity are discussed as possible factors for protecting against cognitive decline in later life. The findings have implications for advancing supportive policies and practices related to maximizing the benefits of education and physical and cognitive activities for cognition in middle age and later life
Socioeconomic Status and Parenting Style From Childhood
The findings advance the understanding of the long-term consequences of SES and psychosocial factors in early life that can lead to optimal cognitive function in middle and old age
