An Analysis of Dee’s Identity Construction from the Perspective of Consumer Culture  [PDF]
Qian Zhang, Haimei Liu
Advances in Literary Study (ALS) , 2014, DOI: 10.4236/als.2014.23012
Abstract:

This paper will focus on the role of the consumer culture in Dee’s identity construction in Everyday Use. Dee’s identification with the female image and her aestheticization of the reality and the history of African American reflect consumer culture acts as the “Other” in the Dee’s identity construction. However, consumption culture also serves as the domain where Dee establishes her self-identity as a black female in a white-dominant world. Through the exploration of the double role of consumer culture in Dee’s identity construction, this thesis advocates that in Every Use Walker presents the new black women dilemma in white-male consumer society and her thought on how to construct black female identities under the invasion of consumer culture into the American South, so that to some extent it makes certain contribution to the issue how women construct their own identity in the consumer society full of survival anxiety.

Is There a Reverse U-Shaped Relation between Financial Development and Income Distribution? Comparison between Developed Countries and Transforming Countries  [PDF]
Zhaoying Liu, Qian Wang
Open Journal of Social Sciences (JSS) , 2015, DOI: 10.4236/jss.2015.33030
Abstract: Researching relation between financial development and income distribution is always a hotspot issue of theory. In 1990s, Greenwood and Jovanovic proposed the reverse U-shaped relation model between financial development and income distribution. Related scholars conducted empirical analysis accordingly but there was always no consistent conclusion. In this paper, whether there is a reverse U-shaped relation between financial development and income distribution is verified via different country types. USA, UK and Germany are taken as representatives of developed country; China, Russia and Brazil are transforming countries to respectively carry out empirical analysis to relation between financial development and income distribution, and it is found that: there is no reverse U-shaped relation between financial development and income distribution in developed countries, nevertheless there is an apparent reverse U-shaped relation in transforming countries.

By taking into consideration of educational evaluation, it focuses on diversification, process, development and practice and sets up a set of new system of assessment and evaluation with combination of “theory, design and application”, which is of great significance to promote curriculum reform of “athletic physiology”, improve teaching quality and exam style and learning style as well as fulfill the teaching goal of the course.
A New Optimality Condition on Generalized Semi-infinite Min-max Problems
LIU Qian
Journal of Chongqing Normal University , 2009,
Abstract: Generalized semi-infinite min-max problem has important relations with optimal control and information technology. It can be used in various engineering fields. So it is very interesting to study the generalized semi-infinite min-max problem is difficult to be solved. To overcome these difficulties, investigators have developed many important progresses of generalized semi-infinite min-max programs. In this paper, we use 11 exact penalty function to remove the constraint conditions of a generalized smi-infinite min-max problem,and then convert this problem into a semi-infinite min-max-min problem. Without the compactness assumption, we prove that the generalized semi-infi-nite min-max problem has the same optimal value, the same set of local and global solutions as the corresponding semi-infinite min-max-min problem, when the penalty parameter is sufficiently large. Using these results, we give an optimality condition for the generalized semi-infinite min-max problem. Furthermore, wediscuss the relations between the optimality condition given in this paper and other existing optimality conditions.
On Current Conditions of Pronunciation Teaching and Learning under Occupation-Related Criterion
Qian Liu
English Language and Literature Studies , 2011, DOI: 10.5539/ells.v1n2p2
Abstract: This study aims to investigate the current conditions of pronunciation teaching and learning in a local university through a questionnaire. The subjects majoring in English Education agree that accuracy rather than intelligibility should be adopted as the criterion for English teachers. Though the importance of pronunciation is well recognized by the subjects, instruction lags far behind the learners’ requirements. Different approaches beneficial for pronunciation learning are also ascertained on the part of learners. Findings suggest that instruction innovation is urgent and competent bilingual teachers should be trained to meet the needs of pronunciation teaching.
Factors Influencing Pronunciation Accuracy: L1 Negative Transfer, Task Variables and Individual Aptitude
Qian Liu
English Language Teaching , 2011, DOI: 10.5539/elt.v4n4p115
Abstract: This paper investigates the influence of three factors on pronunciation accuracy of Chinese adult foreign language learners. Ten target sounds including phonemes and syllables are included in the pre-test, an analysis of which shows that the mispronunciation of the randomly chosen target sounds mainly results from L1 negative transfer. It is observed in intervention that some mispronounced target sounds are more difficult to be corrected than the others. However, the hierarchy of difficulty for pronunciation acquisition cannot be constructed without considering the impact of task variables, for even the same subject’s performance might vary in post-test including vocabulary reading, sentence reading and spontaneous speech, in which tasks individual aptitude in perception, mimicry and monitoring also has a role to play in the improvement of pronunciation accuracy.
Optimization Design of Fracturing Parameters for Coalbed Methane Wells in Dafosi Mine Field  [PDF]
Chuantao Wang, Dongmin Ma, Qian He, Qian Li, Pengcheng Liu
Journal of Power and Energy Engineering (JPEE) , 2017, DOI: 10.4236/jpee.2017.59010
Abstract: Being controlled by the gas content of the reservoir, the productivity of CBM well is also mainly determined by its engineering quality and the physical property of the reservoir. In Dafosi mine field, 22 vertical wells from the “26 + 1” CBM wells project that was implemented since 2014 showed great difference in productivity after fracturing construction. With the consistent geological condition of coal reservoirs, fracturing construction parameters are suggested as the priority factor that controlling the well productivity. In this study, being combined with historical production and geological data, an optimized designation of fracturing construction parameters was established based on systematically comparative analysis of construction parameters such as discharge, the total volume of fracturing fluid, the quality of sand, sand ratio, which provides engineering basis for further fracturing construction of CBM wells.

A Design Method with Knowledge Modeling for Complex Product Based on Ontology  [PDF]
Haibin Liu, Qian Shi, Huan Xiong
International Journal of Intelligence Science (IJIS) , 2013, DOI: 10.4236/ijis.2013.33013
Abstract:

Innovation design for complex products is a difficult issue in the military manufacturing industry. Ontology may provide a feasible way to rebuild the design process for complex products via sharing and reusing of design knowledge. In this paper, a design method used in the innovation design process of the complex products with knowledge modeling is proposed. Knowledge modeling is realized through ontology construction by combining the cycling evolutional theory of constructing ontology and OWL (Ontology Web Language)-based knowledge representation. As a case study, the satellite is selected as one of the complex products. The application domain of the satellite ontology is analyzed. According to the analysis result, the knowledge structure of satellite ontology is put forward based on OWL. The application of satellite product design shows that the method can effectively organize and reuse the knowledge resources in the innovation design of complex product and help companies to create more competitive products based on the existing knowledge and experience.
