灰色系统分析是对"部分信息已知,部分信息未知"的不确定对象进行量化,通过少数据建模实现对系统运行规律的正确描述。利用灰色系统分析方法,能够很好地解决教师胜任力评估面临的"小样本"、"贫信息"的难题。基于高校教师远程教学胜任力模型,通过灰色关联聚类提取远程教学胜任力评估指标的层级,利用层次分析法确定评估指标的单一权重和组合权重,构建了远程教学胜任力评估指标体系。在此基础上,通过评估案例,说明了模拟行为测试、公文筐测试和案例分析3种情境化测评工具的设计方法,展示了利用灰色关联分析和灰色综合评价方法分析群体胜任力排序与等级评定的基本过程,阐释了胜任力评估报告的构成及其含义。 相似文献

教学设备购置方案评价属于复杂的多目标多层次综合决策问题。结合模糊理论、灰色系统理论和层次分析法,构建了教学设备购置方案的评价指标体系,针对层次分析法的不足,改进的层次分析法体现在采用五标度(1-9)法更简便地构造构建模糊互补判断矩阵,极大减少了评判专家的判断难度和权重计算的复杂度,根据灰色理论的灰色关联度分析,对教学设备购置方案的评价指标进行模糊综合群决策评价,为设备选型决策提供科学依据。算例分析表明,提出的模糊灰色层次决策对设备购置方案评价是可靠有效的。 相似文献

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? 相似文献

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. 相似文献

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. 相似文献

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. 相似文献

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. 相似文献

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. 相似文献
