基于粗糙集的决策规则可靠性评估方法     

李一强  吕宁 《大观周刊》2011,(18):123-124,113

粗糙集理论是处理不精确、不准确数据的有效方法，但是通过粗糙集方法获得的决策规则对于不完整的信息承统和随机数据也是不确定的。本文描述了一个用于决策规则的可靠性评价方法。该方法独立于任何专用引申规则方法，并且参数能够被调整以适应不同的信息系统。  相似文献   

南朝诸家玄言诗批评发微     

李斯斌 《宜春学院学报》2011,33(5):28-32

南朝玄言诗批评有别于两晋之时提出的"韵灵旨清"的审美标准。檀道鸾、沈约、江淹、刘勰、钟嵘等人物的批评,并非从其审美标准而言,而渐有以宗《诗》的儒家诗学标准评价玄言诗,且梁代前后稍有不同。  相似文献   

中西政治制度设计中的“人性假定”     

《南通师范学院学报》2011,(3):17-22

任何一种制度的安排,都应该建立在特定的人性认识基础之上。中西不同的人性假定,导致了不同的治政方略和制度路径。西方政治制度理念的基本分析框架,是建立在人性恶论基础之上的权力分立和制衡思想,其基本的哲学判断是＂制度高于人性＂;中国传统政治制度理念的基本分析框架,则是建立在人性善论基础之上的崇尚德治与集权专制思想,其基本的哲学判断是＂人性优于制度＂。＂性善＂与＂性恶＂两种不同的人性假定,导致了中西＂德治＂与＂法治＂不同的政治文化与政治制度设计。＂德治＂与＂法治＂分别构成了中西政治哲学的核心理念。儒家文化中的人性本善假定从民族文化精神和心理的角度看,固然提升了人们对民族文化的自尊自豪感、民族自信心以及民族凝聚力,但却对中国政治发展也产生过一些不良影响。中国传统的德治思想必须突破和超越人治的范畴,必须在私人领域和公共领域两相区分的前提下,参照西方的宪政理念与法治经验,方可为当代中国的政治建构提供有益的借鉴。  相似文献   

Co-occurrence of adverse childhood experiences and its association with family characteristics. A latent class analysis with Dutch population data     

《Child abuse & neglect》2019

BackgroundAlthough adverse childhood experiences (ACEs) are relatively common among children, there is limited knowledge on the co-occurrence of such experiences.ObjectiveThe current study therefore investigates co-occurrence of childhood adversity in the Netherlands and whether specific clusters are more common among certain types of families.Participants and SettingRepresentative data from the Family Survey Dutch population 2018 (N = 3,128) are employed.MethodWe estimate Latent Class Analysis (LCA) models to investigate co-occurrence of ACEs. As ACEs we examine maltreatment, household dysfunction, demographic family events, as well as financial and chronic health problems. Gradual measures for maltreatment and financial problems are studied to make it possible to differentiate with regard to the severity of experiences.ResultsOur results show that four ACE clusters may be identified: ‘Low ACE’, ‘Moderate ACE: Household dysfunction’, ‘Moderate ACE: Maltreatment’ and ‘High ACE’. Regression analyses indicated that mother’s age at first childbirth and the number of siblings were related to experiencing childhood adversity. We found limited evidence for ACEs to be related to a family’s socioeconomic position.ConclusionThe found clusters of ACEs reflect severity of childhood adversity, but also the types of adversity a child experienced. For screening and prevention of childhood adversity as well as research on its consequences, it is relevant to acknowledge this co-occurrence of types and severity of adversity.  相似文献

Finding the missing Einsteins: Expanding the breadth of cognitive and noncognitive measures used in academic services     

《Contemporary educational psychology》2020

Education researchers, policymakers, and practitioners are concerned with identifying and developing talent for students with fewer opportunities, especially students from historically marginalized groups. An emerging body of research suggests “universally screening” or testing all students, then matching those students with appropriate educational challenges, is effective in helping marginalized students. However, most tests have focused on two areas: math and verbal reasoning. We leverage three nationally representative samples of the U.S. population at different time points that include both novel cognitive measures (e.g., spatial, mechanical, and abstract reasoning) and non-cognitive measures (e.g., conscientiousness, creativity or word fluency, leadership skill, and artistic skill) to uncover which measures would improve proportional representation of marginalized groups in talent identification procedures. We find that adding spatial reasoning measures in particular—as well as other non-cognitive measures such as conscientiousness, leadership, and creativity—are worthwhile to consider for universal screening procedures for students to narrow achievement gaps at every level of education, including for gifted students. By showing that these nontraditional measures both improve proportional representation of underrepresented groups and have reasonable predictive validity, we also broaden the definition of what it means to be “gifted” and expand opportunities for students from historically marginalized groups.  相似文献

字本位理论和汉语语法的研究策略     

陈默 《临沂师范学院学报》2004,26(1):61-64

“字本位理论”的主要观点为“字”是汉语语法结构中的基础单位。汉字具有非线性单位性质，它以汉语音义结合的理据性为基点，在汉语语法结构中处于核心地住。以字为本位，有助于消除古今汉语研究的断层，建立起古今汉语研究的共同轴心，形成方法论的基础，并使之推理成汉语语法一种独特的研究策略。  相似文献
