An Analysis of a Book Sharing Discussion
—The Pedagogical Implication of Exploratory Talk

Lu Liu
Creative Education (CE) , 2018, DOI: 10.4236/ce.2018.96069
Abstract: The use of group discussion in language classrooms is a well-researched topic. The underlying assumption is that group discussion benefits students in their cognitive development and thus helps learning. However, previous studies show that different types of talk may have different effects on students’ cognitive development. In this paper, one type of talk is evaluated for the contribution it makes to students’ learning in groups which is defined by?Fisher (1993)?as exploratory talk. The data recorded was primary students working together on a book sharing discussion, and the analysis is qualitative. From a video of children discussing a book, the author concludes that the children do well in terms of mutual respect and working together. The potential contribution and the limitation of exploratory talk are discussed. She has doubts whether the best can be achieved without teacher guidance. It is concluded that an asymmetric relationship is needed in group discussion and the instructor plays an essential role in modeling, assessing and giving feedback, which optimizes exploratory talk.

Journal of Human Resource and Sustainability Studies (JHRSS) , 2019, DOI: 10.4236/jhrss.2019.71005
Abstract: Based on high-order theory and green supply chain management theory, this paper takes 251 manufacturing enterprises in China, the United States and Vietnam as samples to study the impact of corporate Top Management Characteristic on green supply chain management, and green supply chain management and enterprises, and then introduces competition intensity to explore whether it plays a moderating role in the relationship between GSCM and firm performance. The results show that the age, education level and tenure of executives significantly positively affect green supply chain management practices; green supply chain management practices have a positive impact on corporate environmental performance; while green supply chain management practices cannot directly improve economic performance. However, it can promote economic performance by improving environmental performance; competition intensity plays a positive role in the relationship between green supply chain management practices and economic performance.
Capital Control, Financial Depth and the Demand of Foreign Reserves: Evidence on 1994-2013 Data in China  [PDF]
Dianlei Lu, Zhixin Liu
Open Journal of Social Sciences (JSS) , 2014, DOI: 10.4236/jss.2014.29002

We combined foreign reserves, capital control and financial depth with other economic variables in the same model and discussed the factors that affect the demand of China’s foreign reserves. The results showed that 1) a considerable number of foreign reserves are passively accumulated, for instance, stronger capital controls deeper financial system will lower the demand of foreign reserves; 2) the ratio of Hot Money/GDP is more significant than the FDI/GDP as a proxy of foreign reserves’ protective demand.

Research on Influence of Shopping APP’s Characteristic on Consumer’s Impulse Buying  [PDF]
Zhichao Liu, Zhouwei Lu
Modern Economy (ME) , 2017, DOI: 10.4236/me.2017.812099
Abstract: Based on the SOR theory, this study examined the influence of the knowledge, convenience and entertainment of APP on the consumer’s intention to buy, with 624 consumers who had APP shopping experience. The mediating variable of this study was the sense of pleasure and arousal of psychological emotion. The study findings showed that: 1) shopping APPs knowledge, convenience and entertainment represented the most obvious features of shopping APP; 2) pleasure was completely mediated by the shopping APP’s knowledge and entertainment on impulse buying intention, partly mediated by the convenience on impulse buying intention; 3) arousal was completely mediated by the shopping APP’s knowledge and convenience on impulse buying intention, partly mediated by the entertainment on impulse buying intention.
Predicting the Permeability of Fractured Porous Rock  [PDF]
Wenjing Lu, Haojiao Liu
Engineering (ENG) , 2018, DOI: 10.4236/eng.2018.102004
Abstract: Fractures are widely distributed in tight reservoirs. Fractures and pore-throats form the flow path of oil/gas/water in reservoirs. How to determine the permeability of fractured porous reservoirs is still difficult. A group of tight sandstone samples are first used to measure the fractures and analyze the distribution rules between numbers and length, angles. The permeability changing with the fracture’s length and density for different matrixes?is then computed by using pore-fracture network model. At last an empirical formula for predicting the permeability related with the fracture’s length and density is fitted based on the computed data.

Abstract: OBJECTIVE: To investigate the correlation between traditional Chinese medicine (TCM) syndrome and short-term prognosis of ischemic stroke. METHODS: TCM syndrome factors and the neurological deficit degree of 464 patients with ischemic stroke were assessed using the Ischemic Stroke TCM Syndrome Factor Diagnostic Scale (ISTSFDS) and National Institutes of Health Stroke Scale (NIHSS) on the 1st, 7th and 14th day from the onset of ischemic stroke. Patients were assigned to the favorable short-term prognosis group and the unfavorable short-term prognosis group, depending on the NIHSS score on the 14th day after onset of stroke. The correlation between TCM syndrome factors and the short-term prognosis of ischemic stroke was studied using the logistic regression model. Then, the receiver operating characteristic (ROC) curves were used to evaluate the predicting capacity of logistic regression mode. Lastly, according to the results of the logistic regression model, the authors investigated the correlation between blood stasis syndrome and the neurological deficit degree of stroke with application of repeated-measures analysis of variance.RESULTS: Blood stasis syndrome (odds ratio=2.924, 95% confidence interval from 1.231 to 6.946, P=0.015) on the 14th day and NISSS score (odds ratio=1.956, 95% confidence interval from 1.701 to 2.250, P=0.000) on the 1st day after onset of stroke were risk factors that could predict short-term prognosis of ischemic stroke. The area under the ROC curves of the logistic regression model was 0.95. There was a tendency for stroke patients with blood stasis syndrome to have higher NIHSS scores than patients without blood stasis syndrome, and there was a decreased NIHSS score with time points delay.CONCLUSION: Blood stasis syndrome is a risk whose diagnosis could predict short-term prognosis of ischemic stroke. Clinically, the application of treatment focusing on activating blood and resolving stasis can improve the short-term prognosis of stroke patients. This study provides an evidence base for dynamic intervention of a comprehensive integrative medical treatment program based on syndrome differentiation for ischemic stroke.
Dealing with the Blank in Books’ Layout Design
Lu Liu
Asian Social Science , 2009, DOI: 10.5539/ass.v4n8p36
Abstract: In traditional Chinese painting, blank functions importantly. But it is different from that of a general sense. It is actually the organic component of the whole piece of art work. Blank has a rich expression, making pictures vivid and lively. In the traditional painting and modern layout design, the content is black, that is, the entity. However, it is the blank that is oversensitive. When every entity is put in the position, there must be some blank to adjust the visual intension so that the strain and dynamic can be released and extended. The virtual space is blank-leaving. The blank in the format is not only for the visual pleasure but for an aesthetic realm it creates for readers.
