 [PDF]


Advances in Physical Sciences (APS) , 2013, DOI: 10.12677/aps.2013.11003
Abstract:

探讨李娜在澳网征战过程中的技战术表现,为提升我国女子网球运动发展提供参考,对李娜所参加的八次澳大利亚网球公开赛比赛技战术进行全面总结,结果表明:在经过外籍教练卡洛斯的技术战术改进后,李娜在发球上降低了球速,强调了角度与落点,ACE数量未降反增,发球得分率2013年较2011年增加了1个百分点;接发球方面赢球率呈现逐年增加趋势,从第一次参加的48.5%增加到2013年的52.2%,增加了3.5个百分点;上网次数逐年递增,但网前得分率不及对手;制胜分多于对手的同时非受迫性失误也多于对手。
To explore the Li Na’s technical performance in the Australian tennis Open, and provide reference for Chinese women’s tennis development, results show that: after a foreign coach Carlos’ technical and tactical improvement, Li Na reduced the speed in the service, emphasized the angle and placement, and ACE number did not fall instead of increases, scoring rate in 2013 increased by 1 percentage points than in 2011. The return of serve win rate is increased year by year, from the first 48.5% increased to 52.2% in 2013, an increase of 3.5 percentage points. The Internet times are increased year by year, but the net score rate is less than rivals. She wined more than rival but more unforced mistakes than rivals at the same time.

异性拒绝对择偶价值感的影响:择偶计量器的检验
The Influence of Mate-Rejection on Self-Perceived Mate Value: Testing the Mating Sociometer
 [PDF]

阮鲁君,
Advances in Psychology (AP) , 2012, DOI: 10.12677/AP.2012.25038
Abstract: 采用回忆范式考察来自异性的拒绝对个体的积极/消极情感、自尊、择偶价值感及择偶标准的影响。实验结果发现:1) 来自异性的拒绝对个体的积极/消极情感产生了影响,自尊在两者之间起了完全的中介作用;2) 异性拒绝通过自尊对择偶价值感产生影响,而择偶价值感在自尊与择偶标准之间起中介作用,由此构建成了一个过程模型。本研究支持和扩展了KirkpatrickEllis(2001)所提出的特定领域社会计量器——择偶计量器的构想:自尊作为一种内在机制,调节着异性拒绝后个体的择偶价值感,并间接影响择偶标准。
The present study which using recall paradigm aimed to investigate the effect of  mate-rejection on positive affect and negative affect, self-esteem, self-perceived mate value, mate standard. The result showed: 1)  Mate-rejection makes an impact on positive affect and negative affect, while self-esteem plays fully the mediating role among them; 2) Self-esteem fully mediated the impact of mate-rejection on self-perceived mate value, and self-perceived mate value fully mediated the impact of self-esteem on mate standard, thus a process model was built. This research supports and expands a conceptualization of the domain-specific sociometer, which is derived from Kirkpatrick and Ellis (2001): self-esteem as a mechanism functions to calibrate self-perceived mate value in response to experiences of mate-rejection, and makes an indirect effect on mate standard.

 [PDF]

梁凤,
Advances in Psychology (AP) , 2014, DOI: 10.12677/AP.2014.42042
Abstract: 情绪智力对个体情绪调节起着重要的作用。采用情绪智力测评量表(EIS)测量370名大学生的情绪智力,从中随机抽取得分较高和较低两个水平的学生各20名作为情绪智力高分组和低分组。通过序列递减任务诱发负性情绪,比较两组被试在负性情绪的情境下的情绪体验差异。结果发现,情绪智力水平高分组在负性情绪诱发情境下,会自动化地调节和控制自己的情绪;而情绪智力水平较低的个体,则未对自己的情绪进行自动化的控制和调节。
Emotional intelligence plays an important role in individual emotion regulation. A sample of 370 college students was tested by Emotional Intelligence Scale. 20 students of higher scores and 20 students of lower scores from this sample were randomly selected to do the next test. Serial Subtraction Task which can elicit negative emotion was used to test the effects of the Emotional Intelligence on individual emotion regulation. The results showed that the students with high Emotional Intelligence could automatically control their emotion in the negative emotion-eliciting context, but the students with low Emotional Intelligence would not control their emotion in this kind of context.

Abstract:
双稳系统中的不稳定点对图像增强起到了决定性的作用,使其充当了一个阈值的角色,在一定条件下,使得不稳定的点(也就是阈值)趋于稳定的点,以实现图像增强。本文研究了一类双稳系统,分析了该系统的线性稳定性,利用该性质,在特殊的时间点下,通过初值遍历每一个像素值,实现了图像直方图均衡化,达到了图像增强较好的效果。
The unstable point in the bistable system plays a decisive role and acts as a threshold in image enhancement. Under certain conditions, let the unstable point (that is, the threshold) tend to a stable point in order to achieve the image enhancement. In this paper, a class of bistable systems is studied and the linear stability of the system is analyzed. By using this property, the image histogram equalization is realized by traversing each pixel value at the special time point. Better results.
