关于选择函数形式的Arrow不可能性定理的注记

研究了社会选择中的不可能性定理．首先定义社会选择函数，给出理性社会选择函数的形式化描述，并定义选择函数形式的Pareto准则、无关方案独立性条件和非独裁性条件．在此基础上，探讨了选择函数据架下的不可能性定理，得到了选择函数形式的Arrow不可能性定理和Sen寡头独裁不可能性定理.     

当论域是无究集时选择函数的公理化特征

本文考察论域是无究集时基于t-模的选择函数。讨论解的控制性质；然后分别在Fuzzy偏爱关系具有次非循环性、拟传递性、强拟传递性之下，研究正则选择函数的公理化特征，分析传递性变化对选择函数权理化特征的影响。     

偏好选择情结及其证明

偏好选择情结作为最根本的选择规则先天地根植于人类的心中。无论对于选择群体还是单主体选择的个体而言,基于偏好选择情结构建的选择函数是有解的。选择中,如果以偏好选择情结为出发点,理论上选择主体是能够做出选择的。某些选择困境的出现,是在偏好选择情结之外附加了选择规则的结果。     

我国对日软件承包深度发展的影响因素分析

对日软件外包业务能够给承包方带来大量利润．因此,来自中国、印度为首的国家的承包企业越来越多,使得对日软件承包市场竞争加剧．通过分析服务外包发包商选择函数的14个深度发展影响因素,发现人力资源储备不足、行业成熟度低、相关法律法规不完善、税收及企业规模和财务能力有待提高、管理能力低等五个制约对日软件外包行业深度发展的因素,并提出相应对策,以期对我国对日软件承包产业健康发展提供有价值的参考依据．     

探究高中数学的主线——函数

函数贯穿于整个高中数学的学习,同时其本身又占有非常重要的地位.学习好函数知识对整个高中数学的学习至关重要,把握函数思想可以灵活解决各个章节知识问题.一、函数相关知识学习函数要了解函数定义域和值域,会根据需要选择函数的表达方式(图像、列表、解析法);掌握基本函数的图像,并结合函数的性质(单调性、奇偶性、周期性、特殊值)描绘图像,可由图像的平移、伸缩、对称、翻折得到新函数图像;利用图像性质解决单调性、最值等问题.     

时间序列函数的几个性质

应用代数学知识,研究时间序列在左移、右移、复制、加、选择函数的作用下的性质.     

函数“依图选图”问题的几种解法

因为函数图象是高中数学知识的根基之一,所以函数图象一直是历年高考选择题的命题热点.高考函数图象选择题的类型有"依式选图"和"依图选图"两类.依式选图是指根据函数解析式选择函数图象选项;依图选图是指根据图象或图形选择函数图象选项.其中后者比前者难度大,综合性强,思维能力要求高,具有高考选拔和区分功能.     

互余函数图象在高中物理解题中的妙用

在物理解题中,恰当选择函数图象会给解题带来很大的方便,文章介绍一种利用互余函数关系快捷分析物理过程的方法.

Western and Eastern culture differences in commercial field

The communication of people partially is the communication of cultures. Culture has a direct effect on international commercial activities in all aspects. Different conceptions about time, space, equality, law and the like, lead people to deal with things in different ways. So to know cultures of the counterpart is to facil-itate our enterprises so as to have a smooth and successful communication in commercial activity.

漏洞百出的教育

Many college freshmen arrive woefully unprepared to do college work, and as disadvantaged populations continue to grow, the share of the American work force that has made it through college is expected to plummet. Many experts blame that educational failure not just on high schools but also on colleges. School & College, a special report by The Chronicle, looks at efforts to fix the system. What reforms would better prepare students for college? What should schools and colleges be doing differently? How should state and federal officials help?     

只要努力,不要后悔

There are numbers of crossroads on our long and unpredictable life journey where we totally have no idea about which direction to choose. No matter what our decision is, we should not turn back, but face the music and go ahead instead. I am this kind of girl who always does try without regretting, one example is how I dealt with my love.     

浅谈移民问题

Migration occurs behind a variety of reasons and has a great effect on the whole world. People may migrate in order to improve their economic situation, or in order to escape civil strife, persecution, and environmental disasters. The impact of migration is complex, bringing both benefits anddisadvantages. This paper briefly talks about the causes of migration, the allocation of benefits, and the ways in which individual countries and the international community deal with this important subject.

团图为数的图中的闭团贯数

Given a graph G,a subgraph C is called a clique of G if C is a complete subgraph of G maximal under inclusion and |C|≥2. A clique-transversal set S of G is a set of vertices of G such that S meets all cliques of G. The clique-transversal number, denoted as TC (G), is the minimum cardinality of a clique-transversal set in G. The clique-graph of G, denoted as K (G), is the graph obtained by taking the cliques of G as vertices, and two vertices are adjacent if and only if the corresponding cliques in G have nonempty intersection. Let F be a class of graphs G such that F={G|K(G) is a tree}. In this paper the graphs in F having independent clique-transversal sets are shown and thus TC (G)/|G|≤1/2 for all G ∈ F.     

Sister Carrie, an Adherent of Desires

Sister Carrie is one of the most controversial characters in American literature.Thought as a "fallen woman" firstly,she was defined as a "new woman" by some critics later. However, by digging into the motivaton behind the whole process of Carrie's "success", the relationship between Carrie and her creator (the author), the social conditions of then American, it can be found that Carrie has never been free-standing on her thought and she has never found her real-sdf even after becoming a famous actress. In a society dominated by mass consumerism Carrie is only an adherent of her own desires. She also is a representative of all those country girls flooded into cities, a symbol and a sacrifice of the urbanization of America in a time countryside was overcome by cities.
