大学生逆反心理与马克思主义理论课教学的调适对策

大学生的逆反心理不仅直接影响马克思主义理论课程的教学效果,甚至会影响到大学生的马克思主义信仰和社会主义核心价值体系建设的成败。文章通过分析大学生在马克思主义理论课程中逆反心理的表现及其产生原因,从马克思主义理论课教学的角度提出了消除其逆反心理的调适对策。     

色彩与情感的契合——浅析色彩与情感在梵高创作中的体现

纵观西方绘画艺术发展史,利用色彩来表达情感的人很多,梵高无疑是其中最杰出的代表。他的一生是短暂而贫苦的,屡遭挫折,备尝艰辛。但他却通过画笔,运用绚烂的色彩,将熟悉的人和物展示在世人面前,其每一幅作品都像一团团生命幻化的火焰。在梵高的艺术世界里,色彩不仅具有最直接的情感表现力,而且被赋予了更加神秘的意义,对现代绘画产生了影响深远。     

基于语料库的fairly和rather语义韵对比分析

通过语料库来研究词语语义韵为词汇学习提供了一个全新的视角。本文以BROWN、CLEC语料库为基础,通过使用检索工具AntConc对节点词fairly和rather进行语义韵的对比分析,从而揭示出中国英语学习者使用这两个词的语义韵特点,并以此对英语教学尤其是词汇教学提出一些建议。     

民间借贷对中小企业发展的作用分析

中小企业发展所需的资本支持有很重要一部分来源于民间借贷,一定程度上起到了弥补银行信贷不足、支持中小企业经济投资等方面的积极作用,但也容易造成企业发展恶性循环、产业空心化等不良结果。应从培育和建立合法的民间金融服务体系、积极推进利率市场化等方面系统规范和引导民间借贷,使其发挥优势。     

Nur77与胸腺细胞阴性选择

Nur77属核甾体激素受体家族,可被多种生长因子或凋亡诱导剂诱导表达,从而调节细胞增殖、分化发育和凋亡.在胸腺细胞的发育中,Nur77是胸腺细胞阴性选择的关键转录因子,对于调节和建立T细胞库发挥特殊的作用.综述了Nur77的结构和生物学特征及其在胸腺细胞阴性选择中的作用及其机制.     

基于小生境原理的免疫检测器集优化

基于否定选择的网络入侵检测系统中,检测器集的质量在很大程度上影响检测速率和检测准确率。基于小生境原理,对根据否定选择算法生成的检测器集中存在的重叠检测器进行高频变异和低频变异,提高了检测器集对非自体空间的覆盖率。根据否定选择算法的仿真实验的结果表明优化后的检测器集的整体检测效率明显改善。     

Equatorial aurora: the aurora-like airglow in the negative magnetic anomaly

The most fantastic optical phenomena in the Earth''s upper atmosphere are the auroras. They are highly informative indicators of solar activity, geomagnetic activity, upper atmospheric structures and dynamics, and magnetospheric energetic particles. An area where the geomagnetic field differs significantly from the expected symmetric dipole, such as at the South Atlantic Anomaly, where the magnetic field intensity is low, gives rise to stronger precipitation of energetic particles into the upper atmosphere. Impact excitation and the subsequent airglow emissions exhibit aurora-like dynamic signatures. Nomenclatures of nonpolar aurora or equatorial auroras are similar to those used with the polar auroras owing to their similar excitation mechanisms. This paper provides an overview of the knowledge and the challenges concerning auroral activity at the South Atlantic Anomaly, or more generally, at the negative magnetic anomaly. We emphasize systematic investigation of the equatorial auroras to reveal the temporal and spatial evolution of the magnetic anomaly and the behaviour of energetic particles in near-Earth space.     

The neural bases of vitality forms

Unlike emotions, which are short-lasting events accompanied by viscero-motor responses, vitality forms are continuous internal states that modulate the motor behaviors of individuals and are devoid of the autonomic modifications that characterize real emotions. Despite the importance of vitality forms in social life, only recently have neurophysiological studies been devoted to this issue. The first part of this review describes fMRI experiments, showing that the dorso-central insula is activated during the execution, the perception and the imagination of arm actions endowed with different vitality forms as well as during the hearing and the production of speech conveying vitality forms. In the second part, we address the means by which the dorso-central insula modulates the networks for controlling action execution and how the sensory and interoceptive information is conveyed to this insular sector. Finally, we present behavioral data showing the importance of vitality forms in social interactions.     

相似性分离:选择性注意中干扰和抑制关系研究

选择性注意的研究是当今信息加工理论框架的一个中心概念,而抑制是当前选择性注意研究的前沿焦点。作为注意的机制———抑制在注意选择中对分心物是如何起作用的?抑制和干扰是一种什么关系?实验结果显示:抑制和干扰之间是一种正相关,抑制随干扰的变化而变化。     

减法工程疗法与清理内环境

用十五年医疗实践,初步总结出“减法工程”疗法,是在针刺经络、断食辟谷后通过清除体内非实体性物质而使代谢障碍消失,以证明它和治理物质实体性毒物同样重要。
