Studies suggest that where people live, play, and work can influence health well-being. However, the dearth of neighborhood data, especially data is timely consistent across geographies, hinders understanding effects neighborhoods on health. Social media represents a possible new resource for research.The aim this study was to build, from geotagged Twitter national database with area-level indicators well-being behaviors.We utilized Twitter's streaming application programming interface...

Monoculture and simplified two-crop rotation systems compromise the ecosystem services essential to crop production, diminish agricultural productivity, cause detrimental effects on environment. In contrast rotation, diversified (DCR) refers that contain three or more crops. Despite multiple benefits generated by DCR, its usage has dwindled over past several decades. This paper examined determinants of farmers' adoption decisions perceived DCR in west margins U.S. Corn Belt where diversity...

Crop yield prediction before the harvest is crucial for food security, grain trade, and policy making. Previously, several machine learning methods have been applied to predict crop using different types of variables. In this study, we propose Geographically Weighted Random Forest Regression (GWRFR) approach improve at county level in US Corn Belt. We trained GWRFR five other popular algorithms (Multiple Linear (MLR), Partial Least Square (PLSR), Support Vector (SVR), Decision Tree (DTR),...

Climate variability and trends have significant environmental socioeconomic impacts. Global challenges such as food security, biodiversity loss, water scarcity human health are affected by reference evapotranspiration, temperature, solar radiation, precipitation together, but nonlinear dynamics of these four climatic factors not been assessed simultaneously at the national scale. This leads to unclear limited applications. To address this knowledge gap, we analyzed daily (reference...

Determining the most effective public warnings to issue during a hazardous environmental event is complex problem. Three primary questions need be answered: Who should take protective action? What best and When this action initiated? Warning triggers provide proactive means for emergency managers simultaneously answer these by recommending that target group specified if preset trigger condition occurs (e.g., warn community evacuate wildfire crosses proximal ridgeline). Triggers are used...

Built environment neighborhood characteristics are difficult to measure and assess on a large scale. Consequently, there is lack of sufficient data that can help us investigate as structural determinants health national level. The objective this study utilize publicly available Google Street View images source for characterizing built environments examine the influence chronic diseases behaviors in United States. Data were collected by processing 164 million from November 2019 across...

Collecting neighborhood data can both be time- and resource-intensive, especially across broad geographies. In this study, we leveraged 1.4 million publicly available Google Street View (GSV) images from Utah to construct indicators of the built environment evaluate their associations with 2017-2019 health outcomes approximately one-third population living in Utah. The use electronic medical records allows for assessment between characteristics individual-level while controlling predisposing...

Fuel consumption and air pollution caused by transportation is becoming more serious. Developing an effective meso model to analyze dynamically the temporal spatial distribution of fuel in urban road network has become a research focus. However, parameters used most models traffic field are not detailed enough, generalization ability accuracy these still be improved. For discovering typical driving features relationship with consumption, this paper collected 150 million records within two...

Legal judgment prediction (LJP) is a crucial task in legal intelligence to predict charges, law articles and terms of penalties based on case fact description texts. Although existing methods perform well, they still have many shortcomings. First, the significant limitations understanding long documents, especially those RNNs BERT. Secondly, are not good at solving problem similar charges do fully effectively integrate information articles. To address above problems, we propose novel LJP...
