论厂商在货品与要素市场均衡的对称性
The Symmetry of a Firm’s Equilibrium in the Markets for Product and Factors of Production: A Geometric Exposition
 [PDF]


Business and Globalization (BGlo) , 2016, DOI: 10.12677/BGlo.2016.44016
Abstract:
本文旨在强调诸经济力量之相互相关性和统一性,利用几何图形分析得出,无论在货品与要素市场为完全竞争还是不完全竞争情况下,厂商在货品与要素市场短期均衡均具有对称性;本文套用成长理论的人均资本概念,沿用四象限图形分析厂商在货品与要素市场长期均衡的对称性;并试图讨论厂商发生技术进步时,对最适人均资本量与人均产出量的影响。基于生产过程中厂商在货品与要素市场的双重角色,本文利用几何图形可清楚解说厂商在长短期最适生产决策,同时达成利润最大化与成本最小化的目标,虽图形稍嫌复杂,但创意解说可补教科书之不足,颇富教学意义。
This paper focuses on the unity and interdependence of the various economic forces. I apply geo-metric approach to analyze the symmetry of a firm’s short run equilibrium in product and factor markets and obtain that it has symmetry no matter if the market for product and factors of pro-duction is in perfect or imperfect competition. Base on the per capita capital concept in the growth theory, this paper attempts to apply the 4-quadrant diagram to expound the symmetry of a firm’s long run equilibrium in both product and factor markets. I further discuss the impact of a firm’s technical progress on the optimal per capita capital and per capita output. In order to exploit the dual role of the firm in the product and factor markets of the production process, the geometric figures help to analyze the firm’s optimal production decision in the short and long run equilibrium to achieve profit maximization and cost minimization. It seems that the geometric exposition is quite complicated. Undoubtedly, the above creative and innovative description is a very interesting supplementary reference to the general textbooks in the related field.

Abstract:
本文研究一类带有线性互补约束的随机线性优化问题(SLPCC)。我们首先在一定条件下将该SLPCC转化成随机线性规划,然后提出一种求解SLPCC的抽样平均逼近方法,并给出了相关的收敛性分析。最后,我们给出了初步的数值试验结果。
This paper considers a class of stochastic linear programs with linear complementarity constraints (SLPCC). We first transform the SLPCC into a stochastic linear programming problem under some conditions. Then, we suggest a sampling average approximation method to solve the SLPCC and establish its conver-gence analysis. We finally report some preliminary numerical results.

Abstract: 本研究利用动态竞争模式,以市场共同性与资源相似性为基础描绘出台湾啤酒市场中的竞争者图像,再利用竞争者图像中的相对位置,结合易经的后天八卦图,将对偶竞争者之间的竞争不对称性转换为易经中相应的“卦”。并以其卦辞为决策参考,作为在竞争对抗环境中,从竞争者分析到竞争响应与行动的决策参考。以此建构一套竞争对抗中厂商与厂商间的整合性动态竞争易经决策模式。
In this study, the dynamic model of competition, market commonality and resource similarity are used to form the competitors image. The relative positions in the images of competitors, combined with the eight trigrams map of Yi Jing, will be even asymmetry of competition between competitors into the corre-sponding of the divinatory symbols of Yi Jing for the decision-making reference. The dynamic Yi Jing deci-sion-making model of competition between the manufacturers and vendors is built in this research.

Abstract:
为了解在校医学生一般自我效能感、自尊与人际信任的特点及其关系,并在此基础上为加强医学院校大学生心理健康教育提供可靠的理论依据,本研究采用一般自我效能感量表、自尊量表和人际信任量表对某医学院300名在校医学生进行问卷调查。结果发现:1) 医学生一般自我效能感、自尊和人际信任在性别、生源地、独生非独生方面差异不显著。2) 医学生一般自我效能感在大一和大四、大二和大四两个年级差异显著,其他年级不显著;自尊和人际信任在年级方面差异不显著。3) 医学生一般自我效能感与自尊呈显著正相关;一般自我效能感与人际信任,自尊与人际信任相关均不显著。
The purposes of this study are to explore the status of general self-efficacy, self-esteem and inter-personal trust and the relationship among them of medical students. Then, we try to further pro-vide the theoretical basis for improving the mental health education of medical colleges. 300 par-ticipants were randomly selected to complete the “general self-efficacy Scale” (GSES), “self-esteem Scale” (SES) and “interpersonal trust Scale” (ITS). The results showed that: 1) the general self-efficacy, self-esteem and interpersonal trust have no significant differences in sex, origin, only or non-only child; 2) for self-efficacy, we found significant differences between grade one and grade four and also grade two and grade four, while no significant differences between other grades. No significant differences were found on grade of self-esteem and interpersonal trust; 3) there were positive correlations between self-efficacy and self-esteem. Self-efficacy was not related to interpersonal trust, as well as self-esteem and interpersonal trust.

Abstract: 降水是我国西北干旱内陆河流域出山径流的重要补给来源,很大程度上影响着流域水资源的形成转化、开发利用以及旱涝灾害等过程。本文以讨赖河流域为研究区,基于流域上、中、下游3个典型站点的月降水序列资料,采用混沌理论分析方法,以饱和关联维数和Kolmogorov熵为控制参量,计算并探讨该区月降水序列中的混沌特性。计算结果表明,讨赖河流域降水过程在月时间尺度上具有混沌特征,3个典型站的1/Kolmogorov值得出的流域降水的可预报长度为10个月左右。本研究有助于深入理解干旱内陆河流域复杂降水过程变化规律,对降水径流过程的研究具有序列特征方面的指导意义。
As one of the important sources, rainfall in upper reaches of inland rivers in arid regions of northwestern Chinaplays key roles in not only the surface runoff generation, water transformation and utilization, but also regional drought and flooding to some certain extent. For a better understanding of characteristics of the rainfall, theTaolaiRiver basinis selected as the study area. The method of Chaos is used to determine the two key parameters of the Saturation Correlation Dimension and Kolmogorov Entropy based on the statistics of the observed monthly rainfall series from three representatively hydro-meteorological stations in the upper, middle and lower reaches of the river, respectively. Determination of the two key parameters resulted in relatively chaotic features for the time series of the monthly rainfall across theTaolaiRiver basin. Furthermore, reciprocal of the Kolmogorov entropy described a possible temporal forecasting scale of 10 months in this region. This study can help to understand the complex rainfall regime and analyze precipitation-runoff processes in arid regions.

Abstract:
为了解广东省珠三角地区熟肉制品的安全状况,及早发现潜在的食品安全隐患,为广东省食品安全现状分析和监管提供准确信息,对广东省珠三角地区餐饮服务熟肉制品原料、加工用具、餐饮具及制成品4个环节进行抽样、检测和评价工作。共采集样品75份,检出目标致病菌4株,检出率5.33%。检出2种致病菌,其中金黄色葡萄球菌检出率最高。广东省2010~2011年熟肉制品中存在有食源性致病菌污染,主要是金黄色葡萄球菌污染严重,应加强食品安全卫生监督管理。
To investigate the contamination of food-borne pathogens of cooked meat products in the Pearl River Delta region of Guangdong Province, and provide accurate information for evaluation, analysis and management the present situation of Guangdong Food Safety. 75 samples, including raw materials, implement, dinner set and manufactured goods, were collected from the restaurants and detected pathogenic organisms by following the national hygienic stan-dards and typical methods. 4 pathogenic microorganisms were detected, including 1 strain of Salmonella and 3 strains of Staphylococcus aureus. The accumulative positive rate was 5.33% in all samples. The results shows that the con-tamination caused by food-borne pathogenic organisms exit in cooked meat products in Guangdong. It was necessary to strengthen the administration of food hygienic and promulgate safe practices for Salad.

心理科学进展 , 2000,
Abstract: Fos免疫组织化学法作为一种神经功能活动形态定位法,已在大鼠厌恶性条件反射的神经机制的研究中得到应用。无论是在味觉厌恶性条件反射的研究中,还是在听觉刺激与电击相结合的厌恶性条件反射的研究中,都证明了条件反射建立后,条件刺激能诱导出与非条件刺激相似的c-fos表达的分布,这提示条件反射学习沟通了条件刺激和非条件刺激这两种不同刺激在大脑中的传导通路。
