大学生英语课堂沉默现象原因的问卷分析研究
The Questionnaire Analysis Research on the Causes of College Students’ Reticence in the English Classroom
 [PDF]


Creative Education Studies (CES) , 2013, DOI: 10.12677/CES.2013.12008
Abstract:
在外语教学研究文献中,亚洲学生,尤其是中国学生一直都是与沉默、被动的语言学习者划等号的。很多教师把课堂沉默现象简单归因于亚洲文化因素所造成的本身固有性情,认为不可改变,因而纷纷采用单向的讲座式的教学方法。然而随着国际交流竞争的日益增多和社会对人才要求的提高,这种教学方式的弊端已较为突显。因而要改变沉默现象,就要对课堂沉默现象进行重新认识。通过对江苏六大高校学生和教师问卷调查研究,作者发现学生在英语课堂上的沉默更可能是过去和现在的学习环境所造就的课堂学习习惯,研究还发现学生对公开的课堂参与持积极态度。因此大学生英语课堂的沉默现象的改变有赖于课堂学习环境和气氛的改变。
Asian (especially Chinese) students of English as a second/foreign language have been alleged to be reticent learners in the recent ESL/EFL literature. Many teachers and researchers attribute such reticence to learners’ inherent disposition that is caused by Asian cultural factors, which simply cannot be altered. The one-way lecture-mode teaching methods are consequently adopted in teaching practice. Nevertheless, the disadvantages of such methods have been more and more apparent with the increase of international commu nication and competition and the new requirements for talents’ overall English proficiency. Thereby, a reconsideration of Chinese learners’ reticence in English class is a prerequisite for the change of the traditional ways of teaching. It has been revealed through the questionnaire study on students and teachers from six institutions of higher education in Jiangsu Province that the reticence is more likely to be the performance of learners’ habitual classroom behavior that has been formed in the traditional instructional contexts. It is also found that mainland learners hold a positive attitude to overt participation in classroom activities. Therefore, classroom reticence can be altered with the appropriate learning environment and learning atmosphere.
马克思人类幸福思想的内在逻辑蕴涵
Inherent Logic Implication of Marx’s Thought of Human Happiness
 [PDF]


Advances in Philosophy (ACPP) , 2014, DOI: 10.12677/ACPP.2014.31003
Abstract: 马克思主义哲学的最终价值追求是实现人的自由而全面发展,也是马克思对人的本质、人的幸福的确证的终极关怀。文章以历史唯物主义的基本观点,深入挖掘马克思人类幸福思想的内在逻辑蕴涵,首先从现实的个人的实践活动出发确立历史的存在和生成来把握人类幸福思想的存在前提和现实根基,接着通过对资本主义社会私有制的条件下造成人的本质的异化和人的劳动异化以及扬弃异化、消除人的不幸进行了深入的分析,最后得出只有在共产主义的理想社会下才能恢复人的本质和人类幸福的复归。
The ultimate value pursuit of Marxist philosophy is to achieve human freedom and comprehensive development. It is also the ultimate concern for human nature and happiness confirmed by Marx This article will dig deep into the inherent logic implication of Marx’s thought of human happiness through the basic viewpoints of historical materialism. This article will first start from the real in- dividual practice to establish existence and production of history and to grasp the premise existence and realistic foundation of thought of human happiness, and then will make in-depth analysis of human nature alienation and human labor alienation under conditions of private owner- ship of capitalist society, sublating alienation and eliminating people’s misfortune. Finally we make a conclusion that only under the ideal communist society can we restore human nature and human happiness.

Abstract:
WNK1是WNK家族中第一个被发现的成员,WNK1有多个转录起始位点,在不同的组织有不同的转录产物。进一步的研究发现,WNK1基因1号内含子大片段缺失可导致Gordon综合征。WNK1是肾脏中多个离子转运体和通道的调控蛋白,在维持肾脏钾钠氯离子平衡以及血压调控中起非常重要的作用,因此,WNK1基因被认为是原发性高血压的致病候选基因,并且WNK1的基因多态性可能与普通人群患原发性高血压的遗传易感性相关。本文综述了WNK1的来源、结构与功能,从不同层次阐述了WNK1与原发性高血压的相关性,目的在于指导降压药的临床用药方案及预测其药效。
WNK1 was the first member found in WNK family; it has multiple transcription start sites and dif-ferent transcription products in different tissues. Further researches found that the deletion of Intein-1 in WNK1 gene can lead to Gordon syndrome. WNK1 is a regulatory protein of the renal iron transporters and channels, and plays a very important role in maintaining renal potassium, sodium and chlorine ions balance as well as the regulation of blood pressure, so the WNK1 gene is considered a key genes for essential hypertension. In addition, the WNK1 gene polymorphism may be linked to the susceptibility of the essential hypertension in general population. This review shows the source, structure and function of the WNK1, and investigates the correlation between primary hypertension and WNK1 aimed at guiding anti-hypertensive drugs clinical drug regiments and forecasts.

Abstract:
萤火虫算法是一种新近提出的高级启发式算法,其具有概念简明、需要设置的参数少、收敛性好的优点。对配电网进行区域划分来降低解的维度并对萤火虫算法进行适当改进,提出了基于二进制萤火虫算法的含DG配电网故障定位方法。算例分析结果表明该方法在配电网发生单点以及多点故障,并伴有部分开关信息畸变情况下,均能够得到准确的结果,证明了其有效性。通过与粒子群算法进行对比,验证了萤火虫算法应用于配电网故障定位的快速性与可靠性。
Firefly algorithm is a new advanced heuristic algorithm, which has advantages of concise concept, few parameters need to be set and good astringency. By dividing the distribution network to reduce the solution’s dimension and improving the firefly algorithm, this paper puts forward a new method of fault location for distribution networks with DG based on binary firefly algorithm. Analysis of example shows that the proposed method is able to get accurate results when it is used to locate single fault or multiple faults in distribution networks accompanied by part of the switch under the distortion of information, which proves its effectiveness. Finally, the comparison results with particle swarm optimization algorithm testify its speed and reliability.

 [PDF]

Abstract:
谐波检测是有源电力滤波器(Active Power Filter, APF)的重要控制策略之一,当电网电压不平衡或畸变时,采用传统谐波检测方法会导致APF的谐波检测产生误差,最终的补偿效果变差。本文基于瞬时无功功率理论,推导了完美谐波消除法(Perfect Harmonic Cancellation, PHC)的补偿电流计算公式。PHC法检测谐波时提取了电网电压的正序基波分量,排除电网不平衡和畸变的影响,减小了谐波检测的误差。最后,本文对PHC法进行仿真验证,分别仿真了电网电压正常和电网电压畸变或畸变的情况,并与传统的p-q法和d-q法的补偿效果进行对比,证明了在电网电压不平衡或畸变的情况下,采用PHC法的APF具有更理想的补偿效果,验证了PHC法的正确性和优越性。
Harmonic detection is one of the most important control strategies in active power filter (APF). When the grid voltage is under distorted or unbalanced circumstance, the harmonic detection of APF causes error using the conventional harmonic detection methods, and the compensation effect is unsatisfactory. The compensating current equation of the perfect harmonic cancellation (PHC) is derived based on Instantaneous Reactive Power Theory in the paper. The PHC method uses positive sequence components of the grid voltage without the effect of distortion and unbalance while detecting harmonic. It makes for error reduction. Finally, the PHC method is simulated in the paper when the grid voltage is under normal circumstance or distorted and unbalanced circumstance. The simulation results verify that the APF using the PHC method has more satisfied compensation effect when the grid voltage is under distorted and unbalanced circumstance, and it proves that the PHC method is correct and superior.

城市化进程中郊区农民迁移意愿模型——对广州的实证研究
,
地理科学 , 2009,
Abstract: 基于行为地理学和经济学相关理论,依据农户调查数据,采用定量方法,对影响郊区农民迁移意愿的外在环境因素和内在自身因素进行了分析,构建了城市化进程中郊区农民的迁移意愿模型。模型表明在市场经济环境下,农民的迁移行为选择是理性的,农民是否迁移取决于能否获得预期迁移收益的最大化,而农民的最大化收益又取决于其所处的外在环境因素和内在自身因素的综合作用。
