从介绍英国19世纪批判现实主义小说家萨克雷的生平入手,通过对其代表作《名利场》所完成“描写真实”、“宣扬仁爱”两大任务的深刻揭示,就这位“天才”所显示出来的一系列艺术创新手法进行了评析,并对其存在的历史局限性进行了披露,高度评价了其在英国现实主义小说发展史上坚持真实性原则、不落窠臼而独树一帜的艺术成就。 相似文献

在抒情诗中,潜在于诗句之外的第一人称主体不止一个,"抒情主体"也不仅仅要么是对"诗人",要么是对诗歌世界中的某个对象性"人物"的指涉。以《豹》为个案对抒情主体进行的结构分析提示,诗歌中有多个潜在主体的代换。 相似文献

作为20世纪中国文学史上一个颇具个性和复杂性的存在,孙犁显然受到过始终游离于中心和边缘之间的苏联作家肖洛霍夫的影响。孙犁从坚守知识分子独立立场、热烈追求人道主义、深情眷念故土乡亲等三个方面接受和借鉴了肖洛霍夫的人生观和创作经验,进而形成了自己独具特色的创作风格。 相似文献

离散小波变换将离散时间信号分解为一系列不同分辨率下的离散近似信号和离散细节,紧支的正交规范小波与完全重构正交镜像滤波器(PR-QMF)相对应。在紧支正交小波基的构造条件下,利用余弦调制完全重构滤波器组的方法,实现了M带紧支正交小波基的构造,计算机模拟表明该方法非常简单、有效。 相似文献

含有协变量的复发事件变点模型的参数估计 总被引:1,自引:0,他引:1
针对复发事件数据协变量的重要作用,建立含有协变量的复发事件变点模型,考虑协变量作用于强度率函数的情形。对于此模型,使用最大似然方法得到变点及各参数估计,并得到了变点估计的相合性。最后对于同时存在待估参数和待估变点的似然函数,采用最速上升法进行了数据模拟。 相似文献

Following the MV Rena grounding and oil spill in the Bay of Plenty, New Zealand in October 2011, the Māori community of Maketū were quick to respond to the arrival of oil on their beaches. They asserted their rangatiratanga by establishing their marae as a base and successfully coordinated a clean-up by more than 450 volunteers, feeding these volunteers every day. We interviewed 11 clean-up leaders and volunteers in Maketū to gather information about how the oil spill affected people in the community and how they ensured the success of their clean-up efforts. Many volunteers returned to help with the clean-up day after day over several weeks. Concepts of kaitiakitanga and manaakitanga underpinned the work of the Maketū clean-up organisers. Participants attributed the success of the Maketū clean-up to the speed with which they responded, the support they received from their community and local businesses, and their local knowledge. 相似文献

Much work is carried out in short, interrupted segments. This phenomenon, which we label task juggling, has been overlooked by economists. We study the work schedules of some judges in Italy documenting that they do juggle tasks and that juggling causally lowers their productivity substantially. To measure the size of this effect, we show that although all these judges receive the same workload, those who juggle more trials at once instead of working sequentially on few of them at each unit of time, take longer to complete their portfolios of cases. Task juggling seems to have no adverse effect on the quality of the judges' decisions, as measured by the percent of decisions appealed. To identify these causal effects we estimate models with judge fixed effects and we exploit the lottery assigning cases to judges. We discuss whether task juggling can be viewed as inefficient, and provide a back‐of‐the‐envelope calculation of the social cost of longer trials due to task juggling. 相似文献

Many researchers have explored the advantages of modular product design, its design methods and its effects on product performance. Modular design is, for example, required for product platform, mass customization and postponement in order to achieve greater product variety and differentiation. However, a few empirical studies explicitly examine how to coordinate modular product design in a managerial way. This paper addresses it by conducting multiple case studies with six companies which have successfully adopted modular product design for five years. Seven critical factors are explored in the management of modular product design. These are pre-defined product advantage, selectively used design rules, module definition, system integration, technological newness, internal communication, and supplier and customer involvement. While most of the literature studies the technical dimension of modular design within a firm, this study focuses on the managerial side across the supply chain. It gives new insights on how to manage modular product design and proposes future research opportunities. 相似文献

In a make-to-order environment, lead time and price can play a crucial role in determining the financial success of a firm. Their importance increases when demand is sensitive to the quoted lead time and price. A model is presented which uses the quoted lead time and price as a mechanism to determine the optimal demand level. The relationships between the model parameters and their impacts on the firm's profit is also analysed. In addition, the effect of the number of job requests, and the mean processing time are examined. Based on the results presented in this paper, there is clear indication that the firm's profit is sensitive to the inventory holding rate, and that the inventory holding cost component is redundant in the presence of a tardiness cost component. 相似文献

For the stationary invertible moving average process of order one with unknown innovation distribution F, we construct root-n consistent plug-in estimators of conditional expectations E(h(Xn+1)|X1,…,Xn). More specifically, we give weak conditions under which such estimators admit Bahadur-type representations, assuming some smoothness of h or of F. For fixed h it suffices that h is locally of bounded variation and locally Lipschitz in L2(F), and that the convolution of h and F is continuously differentiable. A uniform representation for the plug-in estimator of the conditional distribution function P(Xn+1?·|X1,…,Xn) holds if F has a uniformly continuous density. For a smoothed version of our estimator, the Bahadur representation holds uniformly over each class of functions h that have an appropriate envelope and whose shifts are F-Donsker, assuming some smoothness of F. The proofs use empirical process arguments. 相似文献
