Social unrest and the Highway Beautification Act of 1965

The recent series of very senseless shootings of both African American males and police officers are chilling visual demonstrations of the current degree of racial tension and social unrest in the United States. Stricter gun control laws are critically important but only part of the issue. Basic human and civil rights are at the heart of the issue. We must move toward a society in which individuals from varied backgrounds are valued, respected, and included. We must all accept the fact that we are all human beings and very much alike. This will require a national effort very similar to the Highway Beautification Act of 1965. We must adopt and implement policies that will specifically address multiple issues (discrimination, racism, marginalization, exclusion, implicit bias, and the lack of economic mobility) serving as drivers of our current social state. A key component should be increased investment in the educational system (starting in primary school) resulting in an increased college graduation rate and the development of curricula on race and racism and supporting cultural sensitivity and implicit bias training from kindergarten through professional schools.     

基于外部性的生态隐性脆弱地区生态与经济协调发展分析

研究指出,“生态隐性脆弱地区”是在“生态脆弱区”基础上提出的新概念,是指在生态脆弱区之外,受人类行为影响较多、暴露度高,存在或潜在生态系统失衡或退化风险的区域。生态隐性脆弱地区具有生态系统复合性、与人类行为相关大、对外界影响反应较缓慢三方面的主要特征。基于生态隐性脆弱地区的外部性分析,应从严格生态考核、严格外来投资审核、引进适用绿色技术、健全制度体系、完善生态补偿、强化理念更新六个方面推动生态隐性脆弱地区生态与经济协调发展。     

当代记忆研究与中枢执行机能

当代认知心理学开辟了记忆研究的新领域 :工作记忆、内隐记忆、前瞻性记忆、记忆歪曲 ,其研究成果突破了记忆模型的传统理论。我们系统地考察了近 2 0年来当代记忆研究方法的演变和实验的主要成果 ,分析了神经心理学在记忆过程中的重要作用。研究表明 ,中枢执行机能与记忆活动具有很强的关联性 ,预示人类记忆理论的重新整合要建立在中枢执行机能的基础上。     

隐性契约与公司股利政策研究

隐性契约以商品所有权分割为存在前提,含有隐性契约价格的商品出售使公司承担对顾客的隐性负债,从而对股利政策产生约束。专用性投资是偿还隐性负债的基础,在公司具备相当盈利能力的前提下,专用性投资与股利支付水平应具有负相关关系。实证研究表明,由于中国上市公司的自生能力不足,内部资金没有成为主要的资金来源,导致专用性投资与股利支付率不具有显著的负相关关系。     

内隐攻击性与同情的关系研究

文章以攻击者和被攻击者的图片为实验材料,对内隐攻击性与同情间的关系作初步探讨。结果发现：（1）攻击性在内隐和外显测验上出现了实验性分离：在外显的再认测验中,被试对被攻击者的记忆和提取显著好于攻击者,但是,在内隐偏好测验中,他们对攻击者的偏好却要显著高于被攻击者;（2）在外显测试中,同情心提高了被攻击者的再认正确率;（3）在内隐测试中,同情心对攻击偏好发生调节作用。     

英语词汇知识维度与发展模式研究概述

从词汇研究的视角与策略方面关注国内外研究者对英语词汇多方面的研究,重点探述其研究方法,尤其是相关的几个方面：词汇知识的维度（包括词汇知识的广度与深度）和词汇知识发展与学习的策略（包括词汇的学得与习得）。研究表明,词汇量的大小影响着语言技能的获得,而词汇知识的质和量与词汇学习模式密切相关。只有运用多种词汇学习策略,提高词汇学习效率,才能缩小词汇宽度（即词汇量）与词汇深度的距离,达到词汇能力和词汇知识的平衡发展。     

论广告语篇的隐形连贯

关于衔接与连贯的关系一直是功能语言学研究的一个重点。随着研究的不断深入,许多语言学家都对Halliday的语篇连贯标准提出了置疑与批评。本文首先在简要回顾韩氏理论的基础上,肯定地指出他所论述的衔接手段对实现语篇显性连贯的重要性;进而结合英语书面广告语篇实例,来重点考察隐性衔接及由其实现的隐性连贯在现实语篇中的体现。     

大学生心理素质自评内隐观的聚类分析

通过大学生心理素质自评内隐观的聚类分析可以看出:生活的信心状况、自信状况和对生活环境的关注程度是大学生自评心理素质的典型指标;大学生的意志品质、思维能力和有意注意能力的个别差异性较大;大学生的理想素质和事实素质存在差距。     

二维波动方程的加权平均隐格式及多重网格算法

提出了数值求解二维波动方程的一种加权平均隐式差分格式，理论分析结果表明其为无条件稳定的，为了克服传统迭代法在求解隐格式方面的困难，采用了多重网格算法，大大加快了迭代收敛速度，提高了求解效率，数值实验结果验证了方法的有效性和可靠性。     

Brief Report: Thin Slices of Racial Bias

The present work examined the detection of racial bias through thin slices of nonverbal behavior. Thirty Black and 30 White American judges rated the nonverbal behavior displayed by White individuals from 20-seconds of silent videotape of an interaction with either a Black or a White confederate. Correlations between judges nonverbal ratings and targets scores on a response latency measure of racial bias (i.e., Implicit Association Test, IAT) as well as on a self-report racial bias measure (i.e., Affective Prejudice Scale) were obtained. Results revealed that relative to White judges, Black judges nonverbal behavioral ratings were better predictors of both White individuals IAT and explicit racial bias scores, but only if those targets were engaged in an interracial dyad. The results are consistent with recent research finding that subtle forms of racial bias leak through nonverbal behavior, as well as with work noting the predictive accuracy of judgments made from thin-slices of nonverbal behavior.Jennifer A.
