A Comparative Study of Water Indices and Image Classification Algorithms for Mapping Inland Surface Water Bodies Using Landsat Imagery
This article presents a comparative study of water indices and image classification algorithms for mapping inland water bodies using Landsat imagery through obtaining 24 high-resolution (≤5 m) and cloud-free images archived in Google Earth with the same (or ±1 day) acquisition dates as the Landsat-8 OLI images over 24 selected lakes across the globe, and developing a method to generate the alternate ground truth data from the Google Earth images for properly evaluating the Landsat image classification results.

The Influence of Context on the Abstraction Level of Children’s Conversations in the Preschool Classroom
Article asserts that despite the numerous studies on the linguistic environment of early childhood education settings (ECE), most of this work disregards contextual factors that may influence abstract conversations and omits characteristics of children’s verbal participation in these interactions. The authors of the article examine how preschool classroom contexts influenced the abstraction level of children’s conversations and how the context and conversational partners’ language influenced children’s verbal participation.

The association between posttraumatic disorder symptoms and addictive behaviours in Macao within a sample of female Filipino migrant workers: a network analysis
Article describes how Filipino migrant workers in Macao are vulnerable to posttraumatic stress disorder(PTSD) symptoms and addictive behaviours due to trauma histories, postmigration stressors, and access to alcohol and gambling venues. The current study investigated differential relations between PTSD symptoms and addictive behaviours in a polytrauma exposed sample of Filipino domestic workers in Macao(SAR), China.

Mortality salience, effort, and cardiovascular response to a bar-press challenge: Remarkably nuanced effects of a death prime on heart performance
Article is a study that presented participants with a bar-pressing challenge relevant to their identity after having exposed them to a prime that made their mortality more or less salient. This study adds substantively to a new line of support for terror management theory and documents the predictive utility of a proposed blended analysis of associated effort processes.

Urban and air pollution: a multi-city study of long-term effects of urban landscape patterns on air quality trends
This article identifies the key urban form determinants of decadal-long fine particulate matter (PM2.5) trends in all 626 Chinese cities at the county level and above. As the first study of its kind, this study comprehensively examines the urban form effects on air quality in cities of different population sizes, at different development levels, and in different spatial-autocorrelation positions.

Ambient urban N deposition drives increased biomass and total plant N in two native prairie grass species in the U.S. Southern Great Plains
This article studies atmospheric nitrogen (N) deposition in urban areas on two native prairie grass species, Schizachyrium scoparium and Nasella leucotricha. Findings indicate that while native prairie grasses may exhibit a positive biomass response to increased N deposition up to ~18 kg ha⁻¹ yr⁻¹, total inorganic N deposition is well above the estimated critical load for herbaceous plant species richness in the tallgrass prairie of the Great Plains ecoregion and thus may negatively affect these plant communities.

Urban Expansion Monitoring Based on the Digital Surface Model—A Case Study of the Beijing–Tianjin–Hebei Plain
This article presents a study of urban expansion in the Beijing–Tianjin–Hebei plain based on ALOS Global Digital Surface Model “ALOS World 3D-30 m” (AW3D30 DSM), Shuttle Radar Topography Mission (SRTM) DSM, and Landsat 7 ETM+ images. The method proposed in this paper can provide rapid and large-scale statistics to study urban construction expansion in the world.

Occupational gender segregation and economic growth in United States local labor markets, 1980 through 2010
This article explores the barrier that gender segregation posses to the exchange of diverse ideas between women and men workers in the United States. The author uses fixed effects regression models to examine the relationship between labor market levels of segregation and economic growth from 1980 and 2010. Results from this study suggest that gender equity is a vital ingredient in the economic development of local United States labor markets.

Religious Exiting and Social Networks: Computer Simulations of Religious/Secular Pluralism
This article uses agent-based simulations in three “artificial societies” (one predominantly religious; one predominantly secular; and one in between), to demonstrate that worldview pluralism within one’s neighborhood and family social networks can be a significant predictor of religious (dis)affiliation but in pluralistic societies worldview diversity is less important and, instead, people move toward worldview neutrality.

Field Environmental Philosophy: A Biocultural Ethic Approach to Education and Ecotourism for Sustainability
This article proposes an educational methodology, called field environmental philosophy (FEP), which orients ecotourism practices to reconnect citizens and nature in order to contribute to local and global sustainability. FEP’s methodology is starting to be adapted in other world regions, such as Germany, Japan, and Mexico, to integrate education and ecotourism for sustainability.

The perils of untested assumptions in theory testing: A reply to Patrick et al. (2020)
This article is a comment responding to a critique by Patrick et. al (2020) of the authors' recent study that raised questions regarding the three-factor model of the Triarchic Psychopathy Measure (TriPM). The reply demonstrates additional problems with the three-factor TriPM model and shows that the seven-factor model out-performs the three-factor model in predicting correlates of psychopathy.

Changes in Deep Soil Water Content in the Process of Large-Scale Apple Tree Planting on the Loess Tableland of China
This article evaluates the effects of orchard development on deep soil water content (SWC) by using a meta-analysis of 162 sampling sites on the loess tableland from 44 peer-reviewed publications. The results showed that the deep SWC in orchards depended on stand age, planting density and annual precipitation.
