结合邓小平理论,讲授辩证法原理

哲学是时代精神的精华，今天讲辩证法原理，必须结合邓小平理论：讲矛盾问题的精髓要结合邓小平理论的实质，讲两点论与重点论的统一应结合两个文明建设的关系，讲量变与质变规律应结合先富与共同富裕方针，讲辩证的否定观，联系如何看待资本主义的问题。

王船山关于知识起源的理性追问

中国哲学史上延续数千载的"生知"与"学知"的对立和冲突,从两个相对立的方面促成了王船山对传统"生知"说的实质性批判,并在此基础上时知识的起源进行理性的追问.他把"生知"剥离为二:生知性理与生知物理,在认知理性层面上批判生知物理,在道德理性层面上肯定并高扬生知性理.他也十分重视"学知",因为他所谓"生知"乃是指生而知性理,"学知"是指学而知物理,并上达会通于性理.无论是生知还是学知,都是为了自觉其性理.生知者也要"力学",学知者"心已具理";生知是向内用力,学知是向外用力.一旦实现了这种自觉,也就达到了天人合一的最高境界.

具有光栅结构方孔的菲涅耳衍射仿真与分析

运用数值计算方法对具有光栅结构的方孔的菲涅耳衍射场的光强分布进行分析和仿真,基于菲涅耳衍射积分和子波相干叠加概念设计了数值算法,给出了相应的MATLAB程序以及仿真结果.从数值分析结果可以直观而明确的看到,具有正弦振幅光栅结构的方孔的菲涅耳衍射花样是带有明显方孔衍射特征的光栅的像,像的清晰度以及与原光栅的相似度由方孔衍射的菲涅耳数以及光栅条纹数决定.与无穷大正弦振幅光栅的菲涅耳衍射类似,当满足一定的条件时也会出现像的频率加倍的现象.

英语短语动词教学实验研究——基于认知的视角

本文通过教学实验证明：集中教授几个隐喻概念的“V ＋down”构式时,对于中等水平的中国成年英语学习者来说,用认知语言学方法（CLA）与意义猜测法相结合的方法比单独采用CLA更有效.实验一用CLA和传统教学法分别进行了教学实验,发现两组教学效果没有显著性差异.实验二选取实验一相同的材料,用CLA与意义猜测法相结合进行教学实验,发现教学效果明显优于单独的CLA.本文还认为,对于缺乏语言环境的中国成年外语学习者,同时教授几个相关隐喻概念的同一短语动词构式比同时教授几个不相关隐喻概念的不同短语动词构式更有效.     

唐代商人入仕问题研究

唐代商人入仕现象在安史之乱后更加多见。唐代商人入仕途径主要有：科举、买官、行贿、告密、捉钱、私觌等。而商人入仕的社会背景原因,一是唐商人经济力量增长进而追求政治地位,二是朝廷财政困难,三是官场日益腐败为商人入仕打开了方便之门。

Differences of math anxiety groups based on two measurements,MASS and EEG

This article investigated how mathematic anxiety (MA) of Korean middle school students could be reduced by comparing analytically their cognitive neuroscience and questionnaire results. We developed a three-hour Complex Treatment Program (CTP) on quadratic functions for the study. In the summer of 2016, we collected data of the pre and post MA questionnaires by Mathematics Anxiety Scale for Students (MASS), the percent of correct answers (PCA) and reaction time (RT) by E-prime program, and also brain-imaging data of the event related potentials (ERP) by Electroencephalograph (EEG) using computer-based functional F-G model. The result indicated the CTP to be effective with the group with higher math anxiety and the group with higher achievement respectively. The MASS result was verified with the better performance of PCA on type G, which was measured by E-prime program. Some interesting patterns were revealed on brain-imaging data by EEG, indicating more brain activities with the MA groups.     

Feeling obliged to “Do Well” or “Not to Fail”? The distinction between approach and avoidance dimensions of oughts

The present studies examined the proposition that there are approach and avoidance dimensions in feelings of obligations, that are associated with a specific network of behaviors, affect, and cognitions in achievement situations. Across 4 studies, results indicated that being motivated by ought-approach was associated with significantly higher positive affect and persistence compared with being motivated by ought-avoidance. Also, arousal and affect could be explained by one's disposition for approach- or avoidance-based oughts. Being motivated by ought-approach was significantly more adaptive compared with avoidance and multiple-ought terms. It was concluded that obligations based on approach or avoidance tendencies represent diverse motivational systems with different cognitions and affective responses.

Genital examinations for alleged sexual abuse of prepubertal girls: findings by pediatric emergency medicine physicians compared with child abuse trained physicians

OBJECTIVE: This study compares abnormal genital examination findings made by pediatric emergency medicine (PEM) physicians to examinations by physicians with training in child sexual abuse in the evaluation of prepubertal girls for suspected sexual abuse. METHOD: A prospective study was performed following the genital examination by a PEM physician of prepubertal girls suspected of being sexually abused. A physician with training in child sexual abuse re-examined those girls whose examinations were interpreted as abnormal by the PEM physicians. The findings and interpretations of the PEM physician were then compared to those by the physicians with training in child abuse. RESULTS: Between October 1994 and October 1998, 46 patients diagnosed by PEM physicians with nonacute genital findings indicative of sexual abuse were re-examined by a physician with training in child abuse. The follow-up examinations were done 2 days-16 weeks (mean 2.1 weeks) after the emergency department visit. The physicians with training in child abuse concluded that only eight of these children (17%) showed clear evidence of abuse. Normal findings were noted in 32 children (70%), nonspecific changes were noted in 4 children (9%), and 2 children (4%) had findings that are more commonly seen in abused children than nonabused children but are not diagnostic for abuse (concerning for abuse). CONCLUSIONS: There was poor agreement between the pediatric emergency medicine physicians and the physicians with training in child sexual abuse. This study suggests that emergency medicine physicians should consider additional training in this area. In addition, all children with abnormal ED examinations should have follow-up examinations by a child abuse trained physician.
