国际金融市场研究方法的逻辑演变——有效市场假说面临的挑战

有效市场假说作为金融经济学的理论基石,无疑是我们研究国际金融市场的重要方法和依据。许多其他得到广泛 应用的金融投资理论皆以此为基础。历经30年的发展,有效市场理论在不断得到支持的同时,也面临了许多新的市场理论的挑 战。混沌理论和分形市场理论,特别是对于市场异象做出新解释的行为金融学,都从不同角度对传统有效市场理论进行了突破。这 不仅为研究国际金融市场提供了新的思路和方法,也对金融市场的决策者和生产者有着巨大的现实意义。     

行政奖励的行政法思考

随着现代政府职能的转变,行政行为表现形式日益多元化,行政机关做出的行政奖励就属于迥异于传统行政行为方式的新型的、有效的行政行为,是世界各国在丰富政府管理手段、提高政府管理水平过程中普遍面临的制度性课题。然而,对于行政奖励的行政法研究,目前在我国仍没有受到应有的关注,导致行政奖励的理论严重滞后于现实要求。     

寻租约束下的行政效率及其对我国行政改革的启示

本文通过经济学模型分析考察寻租行为对行政效率的负面影响。研究发现,不论是外部寻租行为还是政府部门的内部寻租行为,均会造成行政效率低下、社会产出效率下降、社会效用总量受损;但是,选择一个较大的政府规模虽然会影响全社会产出效率,却不一定引起社会效用损失,因此,我国的行政改革并不需要从压缩行政规模入手,而应当努力遏制寻租,坚持走渐进的行政改革道路。     

交通事故认定的法律救济

《中华人民共和国道路交通安全法》将交通事故认定书定性为处理交通事故的证据,公安部的部门规章随即取消了交通事故责任认定的重新认定程序,人民法院也不再受理对交通事故认定不服提起的行政诉讼,使得关系当事人重大权利义务的交通事故责任认定丧失了有效的救济途径。交通事故认定一旦错误。便将给当事人带来极大的危害。因此,有必要正确把握交通事故认定的法律属性,将交通事故认定纳入行政复议、行政诉讼的受案范围,为其引入制约与监督机制,以切实维护交通事故当事人的合法权益,同时应当建立民事附带行政诉讼制度,为公正、高效地解决交通事故损害赔偿纠纷提供一条便捷的法律救济途径。     

论犯罪嫌疑人在讯问中的非语言行为

在人际思想交流中,口头语言的真实含义可以由许多非语言行为的暗示加以扩充或修正。诚实或撒谎的犯罪嫌疑人在讯问中的表现有所不同,通过对其非语言行为进行认真地观察、分析和判断,可以有效地区分谎言。     

政府职能转变的阻力分析

我国改革开放以来如进行的五轮行政体制改革就有四轮把转变政府职能作为核心和重点。但是，职能转变收效甚微。是市场经济主体的不成熟、社会组织发育迟缓、行政体制改革内动力不足阻碍了政府职能的转变，是社会转型期政府的二难处境导致职能转变受阻。我们必须根据我国所处的特殊转型阶段和市场的特定要求，决定“放松管制”的幅度、力度、和方式，同时要高度重视对市场秩序的监管以及对“监管者”权力的监督。唯此，才能保证我国经济和社会转型时期政府职能转变的平稳、有序和有效。     

民事自助行为制度的功能分析及立法选择

自助行为属于私力救济的一种形式,它具有保护利益的特定性、行为的法定性和公力补充性的特征;自助行为制度有利于保护公民的合法权益,降低司法成本,提高司法效率,维护市场经济信用秩序等方面的功能;我国的民事立法中应该引入该制度,以促进我国法制现代化进程。     

A Multi-mediation Model on the Relations of Bullying,Victimization, Identity,and Family with Adolescent Depressive Symptoms

This study investigated a multi-mediation model of the relationship between bullying behavior, peer victimization, personal identity, and family characteristics to adolescent depressive symptoms in 194 high school students, 12–18 years of age. In the first model, peer victimization mediated the relation between bullying behavior and depressive symptoms. In the second model, personal identity mediated the relation between peer victimization and depressive symptoms. In the final model, the two mediation models were combined. The relative influence of family characteristics on all variables in the two mediation models was studied using structural equation modeling. The results supported both mediation models and confirmed the influence of family characteristics on all variables in the mediation models. This study indicates that victimization by one’s peers has consequences for adolescents’ psychological health when their personal identity is affected. In addition, the study was able to model several processes in which family characteristics were related to adolescent depressive symptoms. Moreover, the final combined model (in which the two mediation models and the influence of family characteristics on all variables were confirmed) explained half of the variance in adolescent depressive symptoms.

The Impact of Language Status as an Acculturative Stressor on Internalizing and Externalizing Behaviors among Latino/a Children: A Longitudinal Analysis from School Entry through Third Grade

This study examined the relationship between limited English proficiency status, and internalizing and externalizing behaviors among a sample of Latino/a children (N = 2,840) from the US Department of Education’s Early Childhood Longitudinal Study, Kindergarten (ECLS-K) data set. Results of cross sectional regression and hierarchical linear modeling (HLM) analyses suggest that there is a positive relationship between limited English proficiency and externalizing symptoms, particularly by third grade. Additionally, sex and place of birth also helped to explain externalizing behaviors at various time points in the models. Place of birth and family poverty were significantly associated with internalizing symptoms. Implications for future research and interventions related to internalizing and externalizing behavior among the Latino/a school aged population are discussed.
