Summary: This study evaluates the efficiency of agriculture-based poverty alleviation projects in China and finds that the efficiency level plays an important role in addressing rural poverty. Overall efficiency remains stable, with agricultural production efficiency being the major contributor and social governance efficiency playing a minor role. There is room for improvement in certain input indicators and intermediate variables, such as labor force, fixed assets, and education. In China, it is necessary to revitalize and target poverty alleviation projects, strengthen top-level designs, and address relative poverty issues.

Summary: Ecological poverty alleviation is an effective strategy to address poverty and environmental destruction in poor areas, but its success remains controversial. This study quantified the efficiency of EPA strategies in 28 poor counties in Northeast China from 2005 to 2018 and found that most counties had a below-average EPA efficiency. Factors such as GDP per capita, investment in environmental governance, science and technology expenditure, and urbanization influenced EPA efficiency, while industrial structure and trade had insignificant effects. This study provides a holistic assessment of EPA efficiency and addresses controversies over influencing factors, offering an effective method for regional EPA assessment and improvement in poor regions of China.

Summary: This paper surveys the increasing use of statistical approaches, specifically in the field of non-parametric efficiency studies. It highlights the development of Data Envelopment Analysis (DEA) and Free Disposable Hull (FDH) as standard non-parametric methods and discusses the statistical properties of their estimators. The paper also addresses the limitations of conventional bootstrap methods and introduces a smoothed bootstrap for use with DEA or FDH efficiency estimators. Furthermore, the paper reviews the application of these statistical approaches in various fields, providing confidence interval estimates to assess uncertainty. However, a comprehensive bibliometric analysis of bootstrap DEA/FDH literature and subsequent statistical approaches is still lacking.

Summary: This paper proposes a grey box model for fuel consumption prediction of wing-diesel hybrid vessels based on feature construction. By using both parallel and series grey box modeling methods and six machine learning algorithms, twelve combinations of prediction models are established. A feature construction method based on the aerodynamic performance of the wing and the energy relationship of the hybrid system is introduced. The best combination is obtained by considering the root mean square error, and it shows improved accuracy compared to the white box model. The proposed grey box model can accurately predict the daily fuel consumption of wing-diesel hybrid vessels, contributing to operational optimization and the greenization and decarbonization of the shipping industry.

Summary: Demand-side management is crucial to smart energy systems. This paper proposes a data-driven approach to understand the relationship between energy consumption patterns and household characteristics for better DSM services. The proposed method uses a clustering algorithm to generate optimal customer groups for DSM and a deep learning model for training. The model can predict the possibility of DSM membership for a given household. The results demonstrate the usefulness of weekly energy consumption data and household socio-demographic information for distinguishing consumer groups and the potential for targeted DSM strategies.
