Do High-Achieving Female Students Underperform in Private? The Implications of Threatening Environments on Intellectual Processing.

Stereotype threat research has demonstrated that stereotypes can harm student performance in the face of public evaluation by peers or an experimenter. The current study examined whether stereotypes can also threaten in private settings. Female students completed a math test in 3-person groups, which consisted of either 2 other women (same gender) or 2 men (minority). In addition, students either believed their performance would be broadcasted to their peers (public) or not (private). Results revealed that minority students performed worse than same-gender students in both public and private environments. This finding supports the concept of threatening intellectual environments and shows how far reaching the effects of stereotypes can be. The authors discuss these findings in relation to research on tokenism and to stereotype threat and its educational implications. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Depression in ethnically diverse women: Implications for treatment in primary care settings.

What do health care practitioners need to know about providing adequate care for depressed minority women? This article examined the prevalence of depressive symptoms and clinical depression in ethnic minorities, the extent to which current health service utilization is congruent with needs, and the effectiveness of treatments provided to ethnic minorities in the primary care setting. The impact of ethnic minority women's sociocultural context on symptom expression and help-seeking behavior is also discussed. Finally, the clinical implications for accurate assessment and treatment of ethnic minority women by both medical and mental health practitioners working in the primary care sector are addressed.

Increasing the number of psychologists of color: Public policy issues for affirmative diversity.

This article identifies the key issues involved in the debate about affirmative action. The June 2003 Supreme Court decisions allowing consideration of race to ensure that there is a "critical mass" of African American, Latino/Latina, and Native American applicants to higher education are addressed. Social psychologists have identified key myths and provided clarifications about the need for and consequences of strategies used to promote equal opportunity for persons of color and women. A brief history of affirmative action and of the problems it was designed to solve is provided. The accomplishments, benefits, and compelling interest of diversity and affirmative action are described, as well as the concerns and counterpoints. The lack of a substantial applicant pool in psychology hinders progress toward diversity. Alternative strategies for remedying this lack beyond affirmative admissions policies in psychology are briefly discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

不平衡数据下基于PSO-BP算法的输电线路弧垂预测

针对架空输电线路弧垂在计算过程中易受测量数据(温度、风速、档距等参数)影响的问题,提出了基于数据预处理的PSO-BP神经网络弧垂预测模型.对收集数据中部分样本缺失的情况,使用合成少数过采样技术(SMOTE)对不平衡样本进行合成;构建PSO-BP神经网络用于弧垂预测,使用不同工况条件的数据训练网络,实现弧垂预测的目的,并将网络的性能与传统的BP神经网络性能进行对比.实验结果表明,与传统BP神经网络模型相比,本文提出的模型进行弧垂值预测后所得的误差绝对值显著降低.本文提出的模型可以加快训练速度、提高预测精度.     

融合视觉风格和标签约束的少数民族服装图像解析

目的 少数民族服装款式结构复杂,视觉风格各异。由于缺少民族服装语义标签、局部特征繁杂以及语义标签之间存在相互干扰等因素导致少数民族服装图像解析准确率和精度较低。因此,本文提出了一种融合视觉风格和标签约束的少数民族服装图像解析方法。方法 首先基于本文构建的包含55个少数民族的服装图像数据集,按照基本款式结构、着装区域、配饰和不同视觉风格自定义少数民族服装的通用语义标签和民族语义标签,同时设置4组标注对,共8个标注点;然后,结合自定义语义标签和带有标注对的训练图像,在深度完全卷积神经网络SegNet中加入视觉风格以融合局部特征和全局特征,并引入属性预测、风格预测和三元组损失函数对输入的待解析图像进行初步解析;最后,通过构建的标签约束网络进一步优化初步解析结果,避免标签相互干扰,得到优化后的最终解析结果。结果 在构建的少数民族服装图像数据集上进行验证,实验结果表明,标注对有效提升了局部特征的检测准确率,构建的视觉风格网络能够有效融合少数民族服装的全局特征和局部特征,标签约束网络解决了标签之间相互干扰的问题,在结合视觉风格网络和标签约束网络后,能够明显提升少数民族服装解析的平均精度,像素准确度达到了90.54%。结论 本文提出的融合视觉风格和标签约束的少数民族服装图像解析方法,能够提高少数民族服装图像解析的准确率和精度,对传承祖国文化、保护非物质文化遗产具有很好的意义。     

我国高校招生民族优惠政策负面评价的反思

我国的高校招生民族优惠政策以少数民族学生为政策对象,是一种补偿性民族优惠政策,这一政策的积极作用是不容否认的。与此同时,高校招生民族优惠政策也遭受了一些非议和质疑,主要包括对政策公平性的质疑、优惠政策引发的“逆向歧视”问题和“优惠政策依赖症”。这些负面评价的出现有着多方面的原因。要解决好这些问题,高校招生民族优惠政策需做适度调整,将文化多样性政策与地区优惠政策进行有机结合是一种较为可行的方式。     

It's the Thought that Counts: The Mediating Effects of Information Processing in Virtual Team Decision Making

Abstract

Previous research shows that although collaboration technology can improve the exchange of information during team decision making, one of the challenges is that this better discussion often does not lead to better decisions. In this paper, we investigate the impact of individual information processing on team decision making. We investigated the effects of two types of collaboration technology when participants were either the member of a team majority or a team minority. There was little impact due to the majority/minority, but the use of collaboration technology that required users to categorize the comments they received from others resulted in increased information processing, which in turn led to better decisions and more satisfied participants.

高效单晶硅太阳电池基区结构设计与参数优化

首先利用TCAD半导体器件仿真软件全面系统地分析了在不同少子寿命的情况下,基区电阻率对常规P型单晶硅太阳电池输出特性的影响。然后基于对仿真结果的分析,提出一种具有非均匀基区的单晶硅太阳电池结构,并对其输出特性进行了仿真研究。结果表明:当少子寿命一定时,存在最优的基区电阻率,使得常规电池的转换效率最大;随着少子寿命的减小,电池最优的基区电阻率减小;提高基区电阻率有利于常规电池长波段量子效率和短路电流的提高,但同时会降低电池的开路电压和填充因子;当少子寿命较低时,非均匀基区结构不具有提高常规电池转换效率的作用。但当少子寿命增大到一定值时,通过优化非均匀基区的表面浓度,非均匀基区结构可有效改善常规电池的电学性能。
