    Nowadays, eco-designing products is increasingly practiced. The next challenge for sustain- ability is to optimize production processes. Biorefi neries are particularly concerned with this improve- ment, because they use renewable resources. To identify the contribution of transformation processes to the overall environmental impacts, Life Cycle Assessment (LCA) appears as the adequate method. A literature review highlights that LCA is mainly performed on biorefi neries to compare biomass feed- stocks between them and to a fossil reference. Another part of environmental LCA compares the impacts of different processing routes. Nevertheless, these evaluations concern already designed pro- cesses. Generally, processes are considered as a unique operation in assessments. However, some criteria like operating can notably modify environmental burdens. The eco-design of biorefi nery pro- cesses can be guided by coupling process simulation to LCA. This method has been emerging in the chemical sector in recent years. Consequently, this paper proposes a new methodological approach to assessing the complete sustainability of biorefi nery processes, since its fi rst design stages. In addi- tion to coupling process simulation and environmental LCA, the other pillars of sustainability will be assessed. Indeed, Life Cycle Costing and Social Life Cycle Assessment can be performed to obtain an integrated methodological framework. The simultaneous optimization of the environmental, economic, and social performances of the process can lead to antagonist ways of improving. Consequently, compromises should be realized. Thereby, the multi-objective optimization can be accomplished by a metaheuristic method supported by a decision-making tool. Finally, the main limits of this method and some perspectives and ways for improving are discussed

    [[abstract]]As proof of educational quality and upgrading competitiveness of graduates in the global job market, business schools in Taiwan committed towards the goal of obtaining accreditation from Association to Advance Collegiate Schools of Business (AACSB), this paper exams the impact of AACSB accreditation on students’ Organization Socialization, Person-Organization Fit (P-O Fit), and learning outcomes. In addition, this study compares organizations with AACSB and those without AACSB accreditation, examining whether significant differences exist regarding student behavior, effectiveness of learning, organizational identification, organizational citizenship behavior, learning satisfaction, and wishes to transfer to another department or school. The results show that Organization Socialization, through P-O Fit, would positively affect students’ effectiveness of learning, organizational identification, organizational citizenship behavior, and learning satisfaction, and inversely affect students’ desire to transfer to other school. Overall speaking, this research offers proof of AACSB accreditation as guarantee of educational quality.[[notice]]補正完
