纳兰容若边塞词在词史上是独特的存在,塞外风物与闺中情愫的巧妙结合,边塞题材与婉约词性的完美统一,显示了纳兰容若卓绝的艺术个性。这源于其独特的人生经历和对情的特殊体认。纳兰对情的体认和表述,受晚明重情、任情的文学观念的影响,词中在乎的是情的充分表达,而不注重边塞景物的猎奇性描写。纳兰词把闺情的叙写置于边塞词的核心,把边塞景物作为情感表现的背景,从而在传统的边塞词领域开拓出新的气象。  相似文献

In this article, an agent‐based framework to quantify the seismic resilience of an electric power supply system (EPSS) and the community it serves is presented. Within the framework, the loss and restoration of the EPSS power generation and delivery capacity and of the power demand from the served community are used to assess the electric power deficit during the damage absorption and recovery processes. Damage to the components of the EPSS and of the community‐built environment is evaluated using the seismic fragility functions. The restoration of the community electric power demand is evaluated using the seismic recovery functions. However, the postearthquake EPSS recovery process is modeled using an agent‐based model with two agents, the EPSS Operator and the Community Administrator. The resilience of the EPSS–community system is quantified using direct, EPSS‐related, societal, and community‐related indicators. Parametric studies are carried out to quantify the influence of different seismic hazard scenarios, agent characteristics, and power dispatch strategies on the EPSS–community seismic resilience. The use of the agent‐based modeling framework enabled a rational formulation of the postearthquake recovery phase and highlighted the interaction between the EPSS and the community in the recovery process not quantified in resilience models developed to date. Furthermore, it shows that the resilience of different community sectors can be enhanced by different power dispatch strategies. The proposed agent‐based EPSS–community system resilience quantification framework can be used to develop better community and infrastructure system risk governance policies.  相似文献

日本战败之后,经历战争的一代知识分子曾经为实现中日邦交正常化而致力于思想与知识生产,但随着世代更迭,战争记忆的传承在思想史上经历了一个断裂时期,而日本的学院体制也妨碍了其中国观的建设性发展。竹内好在这个时期敏锐地察觉到,日本社会对中国日益失去探求心的现象背后隐藏着一个巨大的危险,即在日本,中国有史以来第一次成为“未知国度”。中日之间为了真正消除战争,相互理解并不能仅仅停留在友好的层面,竹内好设想的“内在于日本的中国”至今对我们仍具有认识论的启示意义。  相似文献

In this article, we propose a general class of partially linear transformation models for recurrent gap time data, which extends the linear transformation models by incorporating non linear covariate effects and includes the partially linear proportional hazards and the partially linear proportional odds models as special cases. Both global and local estimating equations are developed to estimate the parametric and non parametric covariate effects, and the asymptotic properties of the resulting estimators are established. The finite-sample behavior of the proposed estimators is evaluated through simulation studies, and an application to a clinic study on chronic granulomatous disease is provided.  相似文献

Cities evolution tree and applications to predicting urban growth   总被引:4,自引:0,他引:4  
China’s unprecedented urbanization and economic modernization have brought about significant growth and land use changes in cities and their surroundings. Traditional analyses of the relationship between urbanization and land use change have not fully incorporated important factors like city function or developmental stage. We define and apply a new visualization and analysis tool—an evolution tree—showing how an understanding of evolutionary pathways taken by growing cities contributes to visualization and forecasting of urban development and spatial expansion. We clustered 253 Chinese cities by type and developmental stage, arranging them in a “tree” structure, with types grouped as branches and leaf position along branches reflecting developmental stage. Urban growth rates are higher for business-oriented, manufacturing-oriented, and functionally comprehensive cities than for those oriented toward tourism. Extent of spatial growth is dominated by city type and developmental stage. Cities evolve along typical pathways, punctuated by occasional leap developments across functional types.  相似文献

Physical activity takes place in different social contexts such as leisure, home, and work. However, the differential associations of these distinct categories of activity with aspects of well-being have rarely been investigated. This study was designed to estimate independent associations of (a) leisure-time, (b) domestic and (c) work-related physical activities with subjective well-being in older adults. A cross-sectional survey was conducted in 2009 with 2,295 community-dwelling older adults aged 65 or older in Kaohsiung, Taiwan. Among them, 307 participants were selected for a 3-year follow-up study in 2012. The results based on cross-sectional and longitudinal analyses demonstrated that leisure-time physical activity, after multivariate adjustment, was positively associated with five dimensions of well-being, including ‘physical’, ‘psychological’, ‘independence’, ‘learning and growth’, and ‘social’ well-being. Household physical activity was positively associated only with ‘social’ well-being. Occupational physical activity was not related to any dimension of well-being. The study suggests that associations between physical activity and dimensions of subjective well-being during later life are dependent on the social context in which the activity takes place. This study indicates that physical activity taken as leisure has greatest potential to enhance the quality of life of older adults.  相似文献

本文从求解梁挠度的二阶差分方程出发,通过Z变换,最后推导出计算挠度和转角的简单公式,使计算过程简化。对于变截面梁和复杂受载下,此法尤为简便。同时,这也是处理离散参数的数学方法—Z变换在力学中应用的初步尝试。  相似文献

学科教材是公民科学素养教育的基础和依据.数学是最重要的基础学科,对数学教材语言的研究,不仅有助于数学教材的编写和评价,且有助于其他学科教材语言的研究,有助于学科教育质量的提高.文章分析了数学教材语言的领域特征,介绍了数学语言表述特征及其对数学教育的影响,并对数学语言中的字符、词及词组、语法结构与专用表达等表述单位的特点进行了分析归纳.语料库技术是语言研究取得系统化、科学、可靠结论的基础.文章还介绍了数学教材语言语料库建设的原则和过程.本研究认为,叙述语言是学科知识的翻译、解释和陈述系统,对其表述特征和习惯的调查分析,有助于提高教材的编写质量,进而促进学生学科知识的获取和学科能力的提高,因此,应该加大力度,对学科教材语言特征进行专门研究.  相似文献

基于社会交换理论,通过对209名员工2个时点的配对问卷调查,探讨了人—工作匹配和工作幸福感的关系及其作用机制,尤其是工作卷入的中介作用和工作技能的调节作用。结果发现:人—工作匹配对工作幸福感具有显著的正向作用;工作卷入在人—工作匹配和工作幸福感之间起部分中介作用;工作技能在人—工作匹配和工作卷入之间起调节作用,即工作技能水平越高,人—工作匹配对工作卷入的正向影响越强。  相似文献
