On Cubic Nonsymmetric Cayley Graphs  [PDF]
Jingjian Li, Bengong Lou, Rui Wang
Open Journal of Discrete Mathematics (OJDM) , 2013, DOI: 10.4236/ojdm.2013.31008
Abstract: Let \"\" be a connected Cayley graph of group G, then Γ is called normal if the right regular representation of G is a normal subgroup of , the full automorphism group of Γ. For the case where G is a finite nonabelian simple group and Γ is symmetric cubic Cayley graph, Caiheng Li and Shangjin Xu proved that Γ is normal with only two exceptions. Since then, the normality of nonsymmetric cubic Cayley graph of nonabelian simple group aroused strong interest of people. So far such graphs which have been known are all normal. Then people conjecture that all of such graphs are either normal or the Cayley subset consists of involutions. In this paper we give an negative answer by two counterexamples. As far as we know these are the first examples for the non-normal cubic nonsymmetric Cayley graphs of finite nonabelian simple groups.
Homotopy perturbation method for fractional-order Burgers-Poisson equation
Caibin Zeng,Qigui Yang,Bengong Zhang
Physics , 2010,
Abstract: In this paper, the fractional-order Burgers-Poisson equation is introduced by replacing the first-order time derivative by fractional derivative of order $\alpha$. Both exact and approximate explicit solutions are obtained by employing homotopy perturbation method. The numerical results reveal that the proposed method is very effective and simple for handling fractional-order differential equations.
Do You Know where Your Money Is? Product Disclosure Statements for Discretionary Investment Services  [PDF]
Emily Lou
Beijing Law Review (BLR) , 2013, DOI: 10.4236/blr.2013.41006
Abstract:

New Zealand capital markets currently do not serve retail investors well, creating investor skepticism regarding participation. A recent Reader’s Digest survey rated financial advisers among the least trustworthy of professions. This article maps the legal implications of the new measures introduced by the Financial Markets Conduct Bill 2011 to guard investor interests in relation to financial products and services. The paper provides a useful critique of the proposed reforms, in particular, whether the “Product Disclosure Statement” (PDS) and the new licensing of fund managers will give retail investors confidence in investing through financial intermediaries. The paper concluded with recommendation for New Zealand regulator to obtain inspiration from overseas model.

An Empirical Study of Content-Based Instruction Applied in Non-English-Majored Graduate English Teaching in the Post-Massification  [PDF]

Creative Education (CE) , 2015, DOI: 10.4236/ce.2015.614158
Abstract: In the post-massification period, it is a beneficial attempt to the reform of English Teaching based on subject content for non-English-majored graduate students. Content-Based Instruction (CBI) has been defined as “the teaching of content information in the language being learned with little or no direct or explicit effort to teach the language itself separately from the content being taught”, which can make non-English-majored graduate students not only learn subject knowledge but also improve their foreign language (English) ability in learning content. Results in this study showed that: in the post-massification period, content-based English teaching could improve the level of motivation and English language ability of students in their English learning, but CBI was not suitable for poor English learners with no good foreign language (English) basis.
An Effective Algorithm for Quadratic Optimization with Non-Convex Inhomogeneous Quadratic Constraints  [PDF]
Kaiyao Lou
Advances in Pure Mathematics (APM) , 2017, DOI: 10.4236/apm.2017.74018
Abstract: This paper considers the NP (Non-deterministic Polynomial)-hard problem of finding a minimum value of a quadratic program (QP), subject to m non-convex inhomogeneous quadratic constraints. One effective algorithm is proposed to get a feasible solution based on the optimal solution of its semidefinite programming (SDP) relaxation problem.
A Survey on English Majors’ Dynamic Trends of Dictionaries Using  [PDF]
Xixiang Lou, Liping Li
Open Journal of Modern Linguistics (OJML) , 2012, DOI: 10.4236/ojml.2012.22010
Abstract: English dictionaries are the necessary tools for English learning, because a good dictionary is a stable resource of language knowledge. Proper dictionary using can stimulate students’ interest, and cultivate their self-autonomy in language learning. With the development of dictionary compiling technology, a variety of dictionaries have come into existence. The most-often-used dictionaries are paper dictionaries and electronic ones. It is assumed by some that the habit of dictionary using can influence the efficiency of the students’ language learning. This article reports on a survey of the diachronic trends of English major seniors (415) in their choice of dictionaries in the course of English learning from junior middle school to the college education. The investigation is to get some information about the subjects’ habits in dictionary-using at different stage of schooling
Integrating Internet-Based Language Laboratory in Teaching Intensive Reading at Non-English-Majored-Graduate Level  [PDF]
Yougen Lou, Pei Xu
Creative Education (CE) , 2015, DOI: 10.4236/ce.2015.614162
Abstract: This paper reviewed a one-term experiment on integrating internet-based language laboratory (IBLL) in teaching intensive reading to first-year non-English-majored graduate students from Yangtze University. Subjects in this study consisted of 58 non-English-majored graduate students in the control group (CG) and 58 non-English-majored graduate students in the experimental group (EG). The results showed that 1) compared with a teacher-dominated approach for CG, internet-based language laboratory English instruction method for EG did a better job in enhancing students’ productive skills; 2) there were significant differences between males in CG and EG, and females in CG and EG.
A Study of Word Meaning Acquisition of Polysemous Words for English Majors  [PDF]
Xiaoxu Wei, Yougen Lou
Creative Education (CE) , 2015, DOI: 10.4236/ce.2015.618204
Abstract: This study investigates the word meaning acquisition of polysemous words for English majors by the way of questionnaire and two word meaning tests. The conclusions are drawn as follows: providing primary meaning to students can help them guess the extended meaning of unfamiliar polysemous words than providing the other extended meanings; the English majors at different language proficiency level show similar acquisition effects in primary meaning but different acquisition effects in the extended meanings. Therefore, in vocabulary instruction, if the word meaning acquisition sequence can be followed and the connections of word meanings can be cherished, the word meaning instruction outcome will be more efficient.
The Impact of Strategy Training on Vocabulary Comprehension  [PDF]
Yougen Lou, Pei Xu
Open Journal of Social Sciences (JSS) , 2016, DOI: 10.4236/jss.2016.43014
Abstract: This article focuses on a study of the effect of strategy training on vocabulary comprehension. 112 sophomore English-majored students at Yangtze University were chosen as participants in a strategies-based instructional treatment or comparison group students receiving the regular vocabulary course. Data were gained through the performance of a set of two vocabulary tasks on a prepost basis by both groups and were analyzed by the tool SPSS17.0. The subsample of 24 students also provided verbal report data to show their cognitive insights into strategy use and the instruction itself. The findings showed that 1) Chinese English-majors used a variety of English vocabulary learning strategies in vocabulary learning, including metacognitive, cognitive and social/affective strategies. 2) The increased use of vocabulary strategies contributed positively to vocabulary and article comprehension.
Effects of Content-Based Instruction to Non-English-Major Undergraduates English Teaching with Internet-Based Language Laboratory Support  [PDF]
Yougen Lou, Pei Xu
Creative Education (CE) , 2016, DOI: 10.4236/ce.2016.74062
Abstract: With development of technology of computer and internet, it is a beneficial attempt to the reform of College English Teaching based on the subject content with Internet-Based Language Laboratory support for non-English-majored undergraduate students. Content-Based Instruction (CBI) has been defined as “the teaching of content information in the language being learned with little or no direct or explicit effort to teach the language itself separately from the content being taught”, which can make non-English-majored undergraduate students not only learn subject knowledge but also improve their foreign language (English) ability in learning content in Internet-Based Language Laboratory (IBLL). 90 non-English-majored undergraduate students in Yangtze University participated in this study for one-year experiment to investigate effects of CBI English teaching with IBLL support. Results in this study showed that: 1) Compared with the control group (CG), both CBI English teaching and CBI English teaching with IBLL support could improve the level of English learning motivation of non-English-majored undergraduate students in their English learning, and CBI English teaching with IBLL support is better in enhancing the level of English learning motivation; 2) compared with the control group (CG), both CBI English teaching and CBI English teaching with IBLL support could improve the level of English language applied ability of non-English-majored undergraduate students in their English learning, and CBI English teaching with IBLL support is better in enhancing the level of English language applied ability; 3) both CBI English teaching and CBI English teaching with IBLL support are limited for some non-English- majored undergraduate students with poor foreign language (English) basis.
