This article argues that elite purges in consolidated dictatorships have a different purpose and logic. Dictators, who have consolidated their position, seek to maximize the efficiency of rule by making the elite obedient through purges. For this purpose, dictators carefully select the purge target by considering various factors. To test this theory, the article examines the pattern of elite purges in North Korea based on an original individual-level dataset, which contains the personal background of 367 North Korean elites and their purge records between 1948 and 2019. Findings suggest that coup-proofing is not the only purpose of elite purges but that ensuring the leader’s political superiority is another purpose of elite purges in consolidated dictatorships.

Article providing an explanation as to why citizens of some states differ from others in their role conceptions, especially those states that were formerly part of the Soviet Union. The authors offer a novel theoretical explanation that accounts for variation in roles, based on each country’s historic relationship with Russia, its emerging relationship with the West and China, and domestic ethnopolitical conditions.

Article presents research that demonstrates Pleurobema riddellii, Louisiana Pigtoe, was likely present in the Trinity River basin during the late Holocene, which indicates questions about its taxonomic validity or presence in this basin are unfounded.

This article investigates whether moving to a state with more expensive childcare is associated with lower odds of maternal employment among mothers who had been employed prior to relocation. Results show that moving to states with fewer childcare barriers is associated with higher levels of maternal employment, partly mitigating the negative labor market effects of interstate migration.

Article studying racial and gender disparities among school re-openings during the COVID-19 pandemic.

Article discusses how the child-caregiver relationship is the foundation for which intervention occurs. The purpose of this study is to explore how researchers and clinicians might collect direct data on IOH to assess the acceptability of an intervention.

Article examines the spatiotemporal characteristics of climate variables, such as humidity index, precipitation, and potential evapotranspiration (ET0) from 1961 to 2014 in the North China Plain (NCP).

This article is a review examining the effects of forest patches on bees and pollination services to determine how to increase pollination service in agricultural landscapes.

Article exploring the ecology of pollinating bees in urban gardens and farms.

Article presents a study (i) assessing and modeling soil erosion vulnerability based on the Analytic Hierarchy Process (AHP) approach in Hoffenthal and KwaMaye communities within the uThukela Catchment, South Africa; and (ii) identifying the relevant sustainable interventions and remedial strategies to combat soil erosion in the study area.

Article is a study mapping forest height by combining photon-counting LiDAR data and Landsat OLI data.

Article estimating the effects of different scenarios of forest fragmentation to find an optimized pattern of forest patches for increasing pollination in an agricultural landscape. The authors use simulated agricultural landscapes and landscape metrics to estimate the relationship between pollination and landscape structure.

Article examining the effects of habitat loss and fragmentation on pollination separately according to the Lonsdorf model. Results show that the effects of habitat loss and fragmentation on pollination are completely different at the landscape and farm levels. This article shows that using the Lonsdorf model could lead to confusing results for the landscape ecologists and farmers who want to reduce the adverse effects of fragmentation on their products by creating new forest patches.

Article documenting the world's southernmost tree along with the condition and growth pattern of the world's southernmost forest on Isla Hornos, Chile. This offers an ideal way to test the relationship between the biogeography of individual species and the effects of climate/climate change.

This article examines how self-transcending human values affect perceptions of immigrant threat. Results show that benevolence and universalism tend to affect perceived immigrant threat in opposite directions. A part of individuals’ anti-immigrant bias does not stem from strictly self-interested motivations, as often proposed, but by a sense of loyalty to the interests of our immediate contacts.

This article examines whether the availability of Head Start during the Great Recession mitigated the impact of this crisis on poverty rates among families with young children. The findings provide clear, evidence-based policy recommendations. Increased federal funding for Head Start is needed to support families during a COVID-19 recession.

Article introduces a semi-automated method for extracting stream channels and channel profiles from high-resolution digital elevation models (DEMs) using image processing techniques. The method is implemented as an ArcGIS Python add-in toolbar named Channel Extraction and demonstrated using a lidar-derived DEM in a study area along the San Andreas fault in California, USA.

This article presents geomorphic analysis of Xiadian buried fault in eastern Beijing plain (China), based on the analysis of a Satellite Pour l’Observation de la Terre (SPOT-5) image, a high-resolution digital elevation model (DEM) derived from an unmanned aerial vehicle (UAV) system, SRTM DEM and field investigation. Results can provide valuable insight into geomorphic analysis of buried and semi-buried active faults in plain areas with increasingly frequent human activities.

Article examining urban cyclists' risk of exposure to harmful concentrations of fine particulate matter (PM₂.₅).

Article studies the morpho-syntax of proper names in German.

Article using panel data from the US Current Population Survey to examine changes in mothers’ and fathers’ work hours from February through April 2020, the period of time prior to the widespread COVID-19 outbreak in the United States and through its first peak. Using person-level fixed effects models, we find that mothers with young children have reduced their work hours four to five times more than fathers.

This article collected detailed primary data—the Elementary School Operating Status database (ESOS)—to measure the percentage of school districts offering in-person, remote, and hybrid instruction models for elementary schools by state in September 2020 to understand the nature and magnitude of school closures across states during the COVID-19 pandemic and its effect on maternal labor force participation. The article shows that schools are a vital source of care for young children, and that without in-person instruction, mothers have been sidelined from the labor force.

Article exploring how religion, social capital, and nativity intersect in the political mobilization of racial minorities. Collaborative Multiracial Post-Election Survey (CMPS) 2016 data is used to examine the connection between social capital, religion, and political behavior in a novel attempt to systematically identify the unique role of churches in the mobilization of racial minority communities.

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.
