Based on the romantic literary theory,this paper studies the signs of the modern romantic literature. Scholars have tried to connect the issues of romanticism with those of modernity since the climax of the post - modernist cultural studies. With the increasingly deep discussion of post - modernism,people happen to find that romanticism revived quietly in the so - called post - modernist aesthetic purpose and interest. It is not difficult to find in all sorts of discussions of post - modernism the trace of many problems and the thinking styles where romanticism has been involved. The seemingly same source lies in the problems of modernity, which has aroused widespread concerns from the academia. In this paper,the author believes that romantic literature focuses on portraying typical characters to express their emotional tendency. Modernity,especially aesthetic modernity,expands a new vision for us to re - examine romanticism. In other words,to study the signs of modernity from romanticism can blaze a new path for the study of modernity.

To study the effect of cooperative advertising on the supply chain of deteriorating items, this paper establishes a Stackelberg game model for a two-echelon deteriorating items supply chain composed of one manufacturer and one retailer under a given support program with an exogenous participation rate. The manufacturer as the leader determines the wholesale price and production rate, and the retailer as the follower determines the retail price and advertising strategies. The strategies of the players under the decentralized scenario and the centralized scenario are respectively characterized. Numerical simulations and sensitivity analysis are conducted to gain some managerial insights. It is shown that the pricing, advertising and production strategies are negatively correlated to deteriorating coefficient, and both the profit and the channel efficiency decrease with deteriorating coefficient; The interaction between price, advertising investment and production rate results in a higher retail price of the centralized channel compared to that of the decentralized channel; Implementing the cooperative advertising program does improve the performance of the supply chain in some cases and the participation rate roughly at 0.5 is most preferable, but it is also possible to distort incentive and damage the channel performance when the participation rate reaches a relatively high level.

This article studies a problem of joint pricing and dynamic product quality investment with consumers＇ reference quality effect under the existence of quality inflation. Optimal control models are constructed to maximize the total profit with a limited quality investment capacity, where the demand is sensitive to historical product quality level. The optimal quality investment strategies for i＇mite and infmite planning horizon are given respectively by solving these optimal control models on the basis of Pontryagin＇s maximum principle, which enables the exact trajectory of the optimal quality investment with the reference quality effect over time to be depicted. In addition, an effective algorithm is designed to generate the optimal joint pricing and dynamic quality investment policy for the system. The main difference between the strategy of finite planning horizon and that of infmite planning horizon is that the latter is a constant. Our study indicates that it is never optimal for firm to increase quality investment all the way throughout the planning horizon. The level of quality investment is higher when taking into account the impact of reference quality. Moreover, numerical example is given to illustrate the validness of the theoretical results. Also, sensitivity analysis is carried out to show how system parameters affect the optimal policies, and some managerial suggestions are presented.
