ICT's impact on family solidarity and upward mobility in translocal China

Information communication technologies (ICTs) create new channels and repertoires for mediated communication among parents and their children in mobile locations, thus playing a special role in reinvigorating intergenerational family solidarity in contemporary translocal China. For China's rapid, uneven economic development since 1978, social mobility has been fast growing and many family members are separated into different locations for seeking upward mobility as reciprocal aspirations. Some cases of translocal Chinese, studying, working, and living apart from their elderly parents were studied to investigate ICT's impact on family solidarity within the new dynamics of more symbolic and symmetrical family obligations and interactions. Their demonstrations of redefined sociability and intergenerational relationships via connected presence provide a promising new direction for social support and knowledge exchanges in translocal China with a special attention to the multifacets of mobilities and localities in the lives of the contemporary Chinese. A new model of family solidarity is proposed by the proper use of ICTs as new channels for intergenerational communication to supplement but not to replace the traditional ways of ‘togetherness’ by face-to-face interaction among the elderly Chinese parents and their adult children in remote locations. And this is deployed to reinvigorate parent–child relationships of the ‘relational families’ characterized by ‘autonomy of the generations’ in a balance of individualism and collectivism for seeking upward mobility and social cohesion in order to partly solve the social pressure of aging population and rural–urban divide, especially under the special conditions of China's one-child policy and jumping scale of economic development.     

PISA and scientific literacy: similarities and differences between the nordic countries

In this paper we have set out to search for similarities and differences between the Nordic countries concerning patterns of competencies defined as scientific literacy in the Programme for International Student Assessment (PISA) study. The first part focuses on gender differences concerning the two types of competencies, understanding of scientific concepts versus skills in scientific reasoning, based on analyses of sum scores of groups of items. The second part focuses on differences and similarities between countries based on item‐by‐item analyses. Correlations between each Nordic country (as well as the Nordic group as a whole) and every other country have been used to look for a Nordic pattern. In the last part cluster analysis has been used to see how countries establish clusters and whether these clusters represent meaningful groups in a geographical, cultural or political context.     

Explaining Individual Differences in Reading: on the orthographic component of word recognition

This article first presents a conception of word recognition involving both phonological and orthographic processes. Three different explanations about the origin of orthographic processes in word recognition are then discussed. These explanations are: (1) differences in orthographic memory, (2) differences in phonological processes and (3) differences in leisure time reading. In accord with the third explanation, it is argued that automatic orthographic word recognition is directly dependent on children's amount of reading practice in an out‐of‐school setting. Educational implications of this emphasis on leisure time reading effects are also discussed.     

Micromixer based on viscoelastic flow instability at low Reynolds number

We exploited the viscoelasticity of biocompatible dilute polymeric solutions, namely, dilute poly(ethylene oxide) solutions, to significantly enhance mixing in microfluidic devices at a very small Reynolds number, i.e., Re≈0.023, but large Peclet and elasticity numbers. With an abrupt contraction microgeometry (8:1 contraction ratio), two different dilute poly(ethylene oxide) solutions were successfully mixed with a short flow length at a relatively fast mixing time of <10 μs. Microparticle image velocimetry was employed in our investigations to characterize the flow fields. The increase in velocity fluctuation with an increase in flow rate and Deborah number indicates the increase in viscoelastic flow instability. Mixing efficiency was characterized by fluorescent concentration measurements. Our results showed that enhanced mixing can be achieved through viscoelastic flow instability under situations where molecular-diffusion and inertia effects are negligible. This approach bypasses the laminar flow limitation, usually associated with a low Reynolds number, which is not conducive to mixing.

寻找诗美的感觉──略论二十世纪初新诗流变轨迹

本文对新诗的流变轨迹和诗学价值的探讨和研究,并没有停留在已经形成规范的标准的“文学史意义”上,激情的赞美和无端的批评都无助于真正认识诞生在二十世纪初叶的这一生命诗潮的“文学价值”。论文以冷静的梳理方式,客观地评价了为新诗摇旗呐喊的一批先驱者,同时也对新诗诗美感觉的演变进行了较为清晰的概括。     

水分析化学实验课程的教学改革探微

水分析化学实验是给排水科学与工程专业的重要基础课程之一,是分析化学理论知识和实际操作的联系桥梁。其教学目的是既要加深学生对分析化学中的基本概念和基本理论的理解,更重要的是要培养学生分析问题、解决问题的能力,使其掌握水分析化学中基本的实验操作、实验技能,养成科学严谨的态度。就教学过程中取得的成效、存在的问题进行探讨,在此基础上提出了教学改革的初步方案,力求在实践教学过程中优化资源配置,科学管理,取得教学效益、社会效益、经济效益共赢。     

二维自组织临界米堆模型的普适类

对四方格子上的具有决定性倒塌过程和随机倒塌过程的二维米堆模型的临界行为进行了数值模拟研究.系统经一个暂态过程后达到一个临界态,其雪崩大小的概率统计分布服从幂次规律.决定性倒塌模型和随机倒塌模型不属于同一个普适类,决定性模型的临界雪崩指数为τs=1.09±0.02,τa=1.10±0.02和τt=1.14±0.02.随机模型的临界雪崩指数为τs=1.25±0.02,τa=1.29±0.02和τt=1.40±0.02.
