On one hand, it summarizes the viewpoints of vagueness proposed by numerous scholars, displaying the function of such expressions, stressing the affirmative role; on the other hand, it launches the term into the Chinese first philosophy Daoism, revealing the links of these two good brothers. Then, the paper argues about the insights of the logics put forward by the Chinese and the Western professionals, drawing on the conclusion that the Daoism is concerned with the Dao of vagueness. It is a fuzzy set as well as logics of dialectics with reversion reasoning. The two high context terms resemble the cultures of the East and West. The integration can contribute to the success in business communication. No universal way can guide the business interaction; our heart and soul can soften all the discrepancy and conflict. Harmony can be achieved through a variety of Daoes, each cultural group bearing their own vagueness, silence, rhetoric, and reasoning. The logics of the Dao in business communication are in your eyes, your mouth, your hands, and your heart and soul in particular.展开更多

It addresses the national component of identity formations in order to transform them in light of universal human rights principles. In this article, I seek to strengthen this theory left underdeveloped by Habermas. To do so, I use the idea of moral development which Habermas borrowed from Kohlberg. I argue that Constitutional Patriotism is the missing link in Habermas＇s reading of Kohlberg. I complement Kohlberg＇s reading of moral consciousness with the psychoanalytic idea of individuation. Communication, language, and autonomy all fall into their places in this interdisciplinary puzzle of Constitutional Patriotism spanning over the cultural terrain. This article takes part of the broader project of Constitutional Patriotism here only focusing on the notion of the selfhood.展开更多

Although there is a possibility that Gross Domestic Product （GDP） becomes larger for the abatement cases than the baseline case in the earlier years, it tends to be lower than that in the later years. The longer the time horizon and/or the more severe the abatement, the larger the negative impacts will be. When subsidizing R＆D investment, increase in GDP compared to the baseline case is realized in the middle of the time horizon, and the larger increase tends to be observed for the longer-term cases. These results would be due to technological change induced by the subsidies and emission abatement. Environmental indicators are also improved. We showed that the results were influenced by the target time horizon when using an intertemporal dynamic model.展开更多

文摘We evaluate economic and environmental impacts of climate change mitigation in a country scale considering various time horizons in the analysis applying a single-country dynamic computable general equilibrium model with endogenous technological change.
