本文旨在批判地审视流行于当代美国公共话语的文化身份观。作者发现,人们普遍认为文化身份是一种固定的、排他的实体,具有内在的、积极的道德规范作用。而本文则提出动态的文化身份观,强调文化身份不再墨守成规,而是持续发展的。据此本文提出了"跨文化身份"这一概念,并将其作为文化身份的延伸和对应。从一个开放的视角来看,身份的发展不再局限于单一的原文化。作者从人们在面临不同文化身份交错的种种挑战而做出的"压力—适应—成长"的心理反应来解释身份的变化发展。这种跨文化挑战被描述成推动个体在跨文化学习、认知提升和自我—他者关系取向上的进步,这既有个人意义也有普遍意义。

Lignocellulosic biomass is one of the viable solutions to alleviate the global warming. However, the limited utilization of biomass majorly focused on cellulose and hemicellulose restricts the economic and environmental feasibilities. To cope with this issue, we proposed an integrated process of co-producing 1,6-hexanediol(1,6-HDO) with tetrahydrofuran and adipic acid from biomass, referred to as Strategy A. To compare the impacts of lignin upgrading and feedstock, Strategy B, which co-produces tetrahydrofuran alone, and Strategy C, which is the traditional route to produce 1,6-HDO from fossil fuels, were used. Heat networks are also designed to reduce operating costs and indirect carbon emissions due to energy consumption, saving 87% and 83% of the heat and cooling requirements, respectively, in Strategy A. The market competitiveness of Strategy A was evaluated by determining the minimum selling price through techno-economic analysis, and sustainability was thoroughly investigated by quantifying the environmental impacts through both midpoint and endpoint life-cycle assessments(LCAs).Strategy A was found to be the most favorable both economically(USRDSCHARDOLLAR3,402/ton) and environmentally(-26.9 kg CO_(2)eq.). This indicates that lignin valorization is not only economically but also environmentally preferred. Finally, changes in economic and environmental feasibilities depending on economic, process, and environmental parameters were investigated using sensitivity and uncertainty analyses. The results of these analyses provide valuable insight into bio-based chemical production.
