Participatory Forest management and Gender Inclusiveness within the Community Forest management Groups of Bhutan

Journal of Geoscience and Environment Protection 2024年第4期12卷 12-30页

作者： Norbu Zangmo Takuya Hiroshima Spencer Sibanda Jigme Dorji department of Global Agricultural Sciences Graduate School of Agricultural and Life Sciences The University of Tokyo Tokyo Japan Forest Monitoring and Evaluation Section Forest Monitoring and Information Division Department of Forests and Park Services Ministry of Energy and Natural Resources Thimphu Bhutan department of Information and Computer Sciences Graduate School of Science and Engineering Saitama University Saitama Japan Project management Unit Department of Tourism Thimphu Bhutan

Community forest management groups (CFMGs) in Bhutan exhibit participatory forest management practices that recognize the importance of community’s collective participation in the management of natural forest resources. This approach involves the community in the stewardship of designated forest areas and resources to ensure sustainable livelihoods and realization of forest conservation objectives. The increase of CFMGs in the country has been successful. However, research on the extent of gender-inclusive participation in CFMGs is either insufficient or missing vis-à-vis the allocation of decision-making power. Therefore, this study analyzes the factors influencing gender participation in CFMGs and their integration into decision-making processes. Primary data were collected from 12 study sites spanning 4 regions, complemented by secondary data from the Forest department. Regression models were used to identify factors significantly influencing CFMG member participation in decision-making. The empirical results of this study reveal that gender is a significant factor influencing participation in CFMG decision-making. The study concludes that there is insufficient participation of women members in decision-making processes. Therefore, consideration of gender should be included in the development phase of the CFMG policy in addition to promoting awareness of inequity between gender and the promotion of leadership roles for women in CFMGs.

Improved Scatter Search Algorithm for Multi-skilled Personnel Scheduling of Ship Block Painting

引用

Journal of Harbin Institute of Technology(New Series) 2024年第1期31卷 1-15页

作者： Guanglei Jiao Zuhua Jiang Jianmin Niu Wenjuan Yu department of Industrial Engineering and management Shanghai Jiao Tong UniversityShanghai 200240China Shanghai Ship Technology Research Institute Shanghai 200032China

This paper focuses on the optimization method for multi-skilled painting personnel *** budget working time analysis is carried out considering the influence of operating area,difficulty of spraying area,multi-skilled workers,and worker’s efficiency,then a mathematical model is established to minimize the completion time. The constraints of task priority,paint preparation,pump management,and neighbor avoidance in the ship block painting production are considered. Based on this model,an improved scatter search(ISS)algorithm is designed,and the hybrid approximate dynamic programming(ADP)algorithm is used to improve search efficiency. In addition,the two solution combination methods of path-relinking and task sequence combination are used to enhance the search breadth and depth. The numerical experimental results show that ISS has a significant advantage in solving efficiency compared with the solver in small scale instances;Compared with the scatter search algorithm and genetic algorithm,ISS can stably improve the solution quality. Verified by the production example,ISS effectively shortens the total completion time of the production,which is suitable for scheduling problems in the actual painting production of the shipyard.

Digital Revolution and Job Quality of Lower Class Workers: Quasi-experimental Evidence from the Broadband China Program

引用

China & World Economy 2024年第4期32卷 146-178页

作者： Xiumei Wang Ye Jiang Famin Yi School of Business Fuyang Normal UniversityChina department of Economics Dickinson CollegeUSA School of Economics and management South China Agricultural UniversityChina

This study examines the impact of the digital revolution on the job quality of workers with a specific focus on those at the lowest end of the spectrum in China's domestic labor market. Leveraging exogenous timing variations that result from the implementation of the Broadband China Program across different cities, it provides quasi-experimental evidence concerning the effects of the digital revolution on the job quality of lower class workers, particularly rural–urban migrant workers. Using data from China Migrants Dynamic Survey, this study reveals that migrants' comprehensive job quality index increased by 0.0138 (5.33 percent), and its component indices experienced positive effects after the Broadband China Program was implemented. This study also investigates heterogeneous policy treatment effects among workers with diverse demographic and occupational characteristics. Underlying mechanisms are considered, including positive macroeconomic shocks, increased social interactions, and Internet use. In particular, migrants' attitudes toward local settlement became more positive, suggesting that the positive effects of the digital revolution on livelihood lasted for some time. Taking China as an example, this study contributes valuable empirical evidence of how the digital revolution can affect lower class workers' employment or living conditions in a developing country. Related policy implications are also considered.
