查询词典 identity matrix

Through correlative analysis and path analysis, it finds that (1) the family environment and the colleges and universities environment have direct and indirect influence on self-identity development of students; and (2) the family environment and the colleges and universities environment exert the major effect on self-identity development of students through identity style as mediational variable, so identity style becomes the explanatory base of self-identity status. That is, the predictive effect of diffuse/avoidant identity style for identity diffusion, normative identity style for identity foreclosure, and information identity style for identity achievement respectively is most significant; and (3) family environment that is helpful, supportive, warm, expressive, and promote autonomy and independence possibly makes students form identity achievement or identity moratorium, family environment that is excessively cohesive and warm but lacking independence possibly promote students to form identity foreclosure, and family environment that lacks of supportive and warm possibly make students form identity diffusion; and (4) colleges and universities environments that have better relationship system, clear developmental purpose, and promote to pay attention to societal concerns, critical and explorative qualities, and provide healthy, expressive, democratic, open atmosphere facilitate identity development, in turn form advanced identity. Colleges and universities environments that only emphasize the receival of colleges and universities aims, order and instilments, and scarcely encourage critique, exploration, individuation possibly make students form identity foreclosure. However, the ones that is remote relationship system, and lacking support, and students don't cognize the aim of colleges and universities possibly make students form identity diffusion.

通过相关分析、路径分析发现：(1)家庭环境和学校环境对大学生自我同一性有直接和间接的影响；(2)家庭环境、学校环境对大学生自我同一性影响主要以同一性加工方式为中介变量，同一性加工方式成为自我同一性状态的解释基础，弥散—回避定向同一性风格对弥散型同一性预测力最大，信息定向同一性风格对成就型和延缓型同一性预测力最大，常规定向同一性风格对排他型同一性预测力最大；(3)相互支持、帮助、关心、自由表达和鼓励自主和独立的家庭环境促进大学生同一性的发展，形成成就型或延缓型同一性状态，过度亲密而缺乏独立性特征的家庭环境可能形成排他型同一性状态，而缺乏支持性，关系疏远的家庭环境可能形成弥散同一性状态；(4)良好的关系系统，明确的发展目标，鼓励学生对社会事务关注、倡导批判和探索精神，塑造良好、健康、可供自由表达、民主、开放的文化氛围的大学校园环境促进大学生同一性发展，形成高级、成熟的自我同一性，而一味强调学校目标的接受，强调秩序、灌输，缺乏对批判、探索、个性发展鼓励的学校环境有可能使学生形成排他型同一性状态，但若学校的关系系统疏远，缺乏支持性的民主的风格，目标不能被学生明确感知的学校环境则可能影响学生形成弥散型同一性。

Through difference significance tests and analyses, it finds that (1) man students more possibly form identity achievement, and woman students more possibly form identity foreclosure and identity diffusion; and (2) the difference of self-identity status between man and woman students is associated with various domains; and (3) self-identity status between man and woman students have some similarities that identity exploration has the same importance to both; and (4) grade-one is a period when students face up to more identity crises, and grade-two is key period of identity formation, and grade-three is a developmental period of identity that provides the basis for re-solution of the emergence of new identity crises in grade-four;(5) there is a gradually enhanced direction from lower self-identity statuses to advanced ones from grade-one to grade-three, but there is also a direction that reentry into the identity crisis by grade-four. It indicates that the identity achievement formation does not mean the end of development of self-identity and proves that there is a continuous MAMA cycle in self-identity development; and (6) that students self-identity status mainly is identity moratorium provides some evidence for which there is a Moratorium in student development, and which self-identity formation is not easy; and (7) the development of student self-identity is associated with various domains, what students pay most attention to firstly is vocation, secondly life philosophy, and lower interesting in political and religious domains in ideology; for relational domains, students pay more attention to dating and friendship compared to sex role and recreation domain.

通过差异显著性检验和分析发现：(1)男生更可能形成成就型同一性，女生则更可能形成排他型和弥散型同一性；(2)男女大学生自我同一性的差异与不同的领域相关；(3)男女大学生自我同一性也存在相似性，同一性探索对于男女大学生同样重要；(4)大学一年级是同一性危机面对较多的时期，二年级为同一性形成的关键期，三年级为同一性的发展期，所形成的同一性为四年级所出现新的同一性危机的解决提供了基础；(5)从一年级到三年级存在从低级的自我同一性向高级的自我同一型转变的渐进增强，但到四年级又有重新进入同一性危机的趋势，说明大学生成就型自我同一性的形成并不意味着自我同一性发展的结束，证明了自我同一性发展的MAMA周期持续存在的特点；(6)学生自我同一性状态主要还处于延缓型同一性状态，进一步证明大学生发展心理合法延缓期的存在，以及自我同一性形成不是一件很容易的事情；(7)大学生自我同一性的发展与领域相关，大学生较为关注职业领域，其次为人生观领域，而对政治和信仰领域兴趣较低；另外，大学生对友谊、交往领域较为关注，对性别角色和活动领域关注程度相对较低。

In short, this explorative study for self-identity concept, theory and practice is for the purpose of (1) trying to unitarily understand self-identity concept, in turn to minutely examine the new development of self-identity theory, and to introduce self-identity theories and research methods in western psychology to domestic psychology in order to cause the interest of domestic psychologist to self-identity thesis; and (2) through the empirical study on self-identity of college student, revealing the meaning of self-identity to student development, and the personality characteristics of self-identity status of student, and the characteristics and influential factors of student self-identity development, and the relationship between student self-identity status and mental health condition in order to provide the measurement of empirical study and systematic study data for self-identity researches, in turn to provide basis of theory and method for setting up the theoretical model of Chinese students self-identity; and (3) making up the gaps in empirical researches on self-identity in domestic psychology, opening up a new research domain in colleges and universities student psychology, and enrich the theory on student development researches.

总之，本文对自我同一性概念、理论和实践进行探索性研究，旨在(1)尝试对自我同一性作整合统一的理解并在此基础上，详细考察自我同一性理论的新发展，试图将西方心理学自我同一性理论的发展引入国内心理学，以引起国内学者更多的关注；(2)通过对大学生自我同一性的研究，揭示自我同一性对大学生发展的含义、大学生自我同一性状态的人格特征、大学生自我同一性发展的特征和影响因素、大学生自我同一性状态与心理健康水平的关系，进而为自我同一性的研究提供实证研究的测量工具以及系统的实证资料，为建立中国大学生自我同一性的理论模型提供理论和方法上的基础；(3)弥补国内自我同一性实证研究的空白，开辟大学生心理学研究的新领域，丰富大学生发展研究的理论；(4)当代大学生自我同一性问题的研究既是青年心理学、教育心理学和学校心理学的重要课题，也能为大学生发展和大学教育实践提供心理学依据，特别是在强调创新教育和推进大学素质教育的今天具有重要的实践意义。

In order to analyze the reason for a flawed Iraqi identity, this article delaminates the internal identity of Iraq to two levels——national and sub-national, further distinguishes familial identity, religional identity and ethnic identity on the sub-national level, and studies the relations between national and sub-national identities with looking back at the momentous events in Iraqi history, consequently finds the different influences that various of sub-national identities react on the formation of Iraqi national identity and how the discriminative internal policy intensified sub-national identities, and then builds a theoretical framework with two dimensions from upwards and downwards to explain the reason for unshaped Iraqi national identity.

为了分析伊拉克国家认同没有形成的原因，文章将伊拉克内部认同在国家和次国家两个层次上进行划分，并进一步区分了次国家认同中的家族部落、宗教派系、族群这三个认同类型，然后以国家认同和次国家认同的关系为切入点，研究了伊拉克历史上的几个重大事件，发现了各次国家认同对国家认同的形成具有不同程度的影响，其中族群认同对国家认同形成的破坏作用最大；与此同时，伊拉克前政府歧视性的内部政策强化了各次国家认同，是造成伊拉克国家认同没有形成的另一个原因，从而从上、下两个维度解释伊拉克国家认同未形成原因的理论架构。

It consists of the next three aspects: firstly, we study Murthys' open problem whether the augmented matrix is a Q0-matrix for an arbitary square matrix A , provide an affirmable answer to this problem , obtain the augmented matrix of a sufficient matrix is a sufficient matrix and prove the Graves algorithm can be used to solve linear complementarity problem with bisymmetry Po-matrices; Secondly, we study Murthys' conjecture about positive semidefinite matrices and provide some sufficient conditions such that a matrix is a positive semidefinite matrix, we also study Pang's conjecture , obtain two conditions when R0-matrices and Q-matrices are equivelent and some properties about E0 ∩ Q-matrices; Lastly, we give a counterexample to prove Danao's conjecture that if A is a Po-matrix, A ∈ E' A ∈ P1* is false, point out some mistakes of Murthys in [20] , obtain when n = 2 or 3, A ∈ E' A ∈ P1*, i.e.
