《太阳帝国》中的中国形象分析     

高尚风 《乐山师范学院学报》2013,(4):36-41

英国作家詹·格·巴拉德在《太阳帝国》中塑造了沉默的中国人形象,他对战争阴霾下的上海的描写,是为了借对"他者"的否定和批判肯定自身。巴拉德对中国形象的塑造采取了意识形态化的策略,在他建构的中国形象背后,则是对自身民族身份的认同困惑,还有隐蔽的帝国主义思想和殖民意图。  相似文献   

《普鲁弗洛克的情歌》叙事的时间特征探析     

王秋菊 《鸡西大学学报》2013,(10):90-92

艾略特的早期诗作《普鲁弗洛克的情歌》中,“时间”不仅是表达主题的手段和技巧,而且以主题内容的形式出现于叙事过程之中,以揭示主题思想。艾略特借助普鲁弗洛克的内心独白,将有限的现实时间下人物的心理过程投射于他的意识反映上,形成了广阔的叙事时空,并通过对“时间主题”叙事功能的揭示与运用,呈现以普鲁弗洛克为代表的现代人的内心状态和生存环境,反映西方人日趋严重的异化感。  相似文献

Exploration versus exploitation in technology firms: The role of compensation structure for R&D workforce     

Victor Cui  Waverly W. Ding  Yoshio Yanadori 《Research Policy》2019,48(6):1534-1549

We investigate the relationship between a firm’s compensation structure and the extent to which its innovation is more exploration versus exploitation oriented. Specifically, we assess two aspects of a firm’s compensation design—horizontal dispersion within job levels and vertical tournament incentives between job levels. A six-year panel of compensation records of 671,028 employees working at 81 U.S.-based high technology firms between 1997 and 2002 are used to construct measures that characterize a firm's pay structure, which are linked to these firms’ patents filed in the U.S. We find that firms with higher-powered tournament incentives in vertical compensation structure report higher fraction of innovation directed towards exploration. Horizontal pay dispersion, on the other hand, shows a negative relationship with the exploration in firms where R&D employees’ age variance is low. In firms where R&D employees’ age variance is high, the negative relationship between horizontal pay dispersion and exploration is muted.  相似文献   

Human capital and innovation: the importance of the optimal organizational task structure     

Tiago Fonseca  Pedro de Faria  Francisco Lima 《Research Policy》2019,48(3):616-627

Management literature has identified high-skilled human capital as a crucial dimension of innovation processes at the firm level. In this study, we introduce an alternative view of human capital based on the tasks that firms’ workers perform. We propose a measure of cognitive analytical and interpersonal tasks: the degree of abstractism. We argue that the level of abstractism of a firm has an effect on a firm's propensity to innovate and on its product innovation performance. We hypothesize that while the degree of abstractism has a linear positive relationship with the propensity to innovate, the relationship between abstractism and product innovation performance follows an inverted u-shaped relationship. We find partial support to our hypotheses using data from more than six thousand Portuguese firms. We discuss how these results change our understanding of the relationship between human capital and innovation at the firm level.  相似文献   

Twenty-four-hour movement behaviours and fundamental movement skills in preschool children: A compositional and isotemporal substitution analysis

ABSTRACT

Studies that have analysed the association between the different movement behaviours and fundamental movement skills (FMS) have considered it in an independent manner, disregarding the compositional nature of 24-h movement behaviours (24-h MB). The aim of this study was to investigate the relationship between the 24-h MB and FMS in preschoolers using a compositional data analysis . Two hundred and four preschoolers (4.5 ± 0.8 years old; 101 boys) provided objectively assessed physical activity (PA) and sedentary behaviour (SB) data (Actigraph wGT3X), and FMS (TGMD-2). Sleep duration (SD) was reported by parents. Association of daily composition of movement behaviours with FMS was explored using compositional analysis and isotemporal substitution (R Core Team, 3.6.1). When considered as a 24-h MB composition (PA, SB and SD), adjusted for age, BMI and sex, the composition predicted locomotor (r² = 0.31), object control (r² = 0.19), and total motor score (r² = 0.35), respectively (all P < 0.001). Reallocation of time from light to moderate-to-vigorous PA was associated with greatest positive changes in total motor score. Achieving adequate balance between movement behaviours over the 24-h period, and its relationship with locomotor and object control skills should be considered and further investigated in early childhood.  相似文献
