左翼剧作家创作的抗战戏剧,通过在地化的书写构建地方意识,能调动民众有关沦陷家园的文化记忆,以此实现对城市生活的文化描摹与艺术化提炼。孤岛上海和陪都重庆分别作为沦陷区和大后方的精神堡垒,两地抗战戏剧创演在构建价值共同体的同时,也受到城市地理要素与地方人文景观的作用,由此呈现出不同面向。在这其中,吸纳海派传统的孤岛戏剧,因直面战场而无保留地彰显精神动员的主旨;地处西部内陆的大后方戏剧,由于受到多重政治势力博弈与权力话语争夺的影响,其表意相对趋于隐晦。

In various applications like personalized search and recommendation, full demographic information is a precondition for many applications’ well performance,but such ideal dataset rarely exists in practical ***’s worse, absence of key characteristics(e.g., baby’s age in maternal and infant commodity recommendation)makes these applications struggle. We design a novel solution to solve the problem of time-dependent demographic prediction. The key insight behind our approach is, we leverage a Time-back-propagation(TBP) method to take the internal time correlation of historical behaviours into consideration and collect all available data to train a classifier, which is a mapping from user’s historical behaviours to the demographic information. We demonstrate the effectiveness of our method through experiments of baby’s age prediction. Our algorithm performs more balanced on each age group, and can predict Baby’s age(BA) accurately in 78.2% on a real-world dataset with 2,058,909 items of a ma jor E-commerce site.

In order to prepare hydrophobic waterborne polyurethane coatings with better performances, the silicon-containing waterborne polyurethane（SiWPU） with functional chain extender hydroxyethyl acrylate（HEA） was prepared first, and then a series of silicon＆fluorine-containing polyurethane/acrylate（FSiPUA） emulsions were obtained with flourine containing acrylic monomer by seed emulsion polymerization, introducing micro-nano SiO2 into FSiPUA emulsion to make the final hybrid emulsion. The properties of Si WPU, FSiPUA and SiO2/FSiPUA were investigated by fourier transform infrared spectra（FTIR）, transmission electron microscope（TEM）, Scanning Electron Microscope（SEM） and some other analytical methods. The results revealed that FSiPUA emulsion particles possessed composite core-shell structure and FSiPUA films with suitable ratio performed better than Si WPU films in hardness, water resistance and solvent resistance. The SiO2/FSiPUA films with micro-nano dual roughness structure showed a water contact angle of 136° with good resistance to acid and alkali.
