浅析色彩教学研究

色彩是人们睁开眼睛就可以看到的物理现象,但是通过色彩视觉的过程我们知道,色彩学是一门涉及物理光学、化学、生理学、心理学、美学等领域交叉研究的学科。为了更好的将色彩运用到画面中,必须充分了解色彩的变化规律。因此,在色彩教学中,学生对色彩的把握能力和以色彩塑造形体的能力两个方面都是非常重要的能力培养。色彩实体的显现与变化,有着不以人们意志为转移的客观的规律:色彩效果的产生和转化过程,却可以充分发挥艺术家的主观能动作用。     

阵形畸变对拖线阵三维探测性能的影响及补偿技术

针对拖曳阵阵形畸变导致的目标检测不准确问题，首先，分析了阵形畸变对拖线阵三维探测性能的影响，并论证了利用实际阵形在垂直方向形成的孔径实现对目标深度信息提取可行性；然后，依据拖线阵中姿态与深度传感器监测数据，提出一种基于阵形自动拟合的三维补偿技术；最后，通过三维补偿技术修正导向矢量，降低导向矢量与协方差矩阵之间不匹配度，解决阵形畸变所导致的目标检测不准确问题。数值仿真结果表明，对畸变阵形进行三维阵形估计和补偿，实现了对未知目标的三维探测，且避免了标校声源对拖线阵实时探测目标的影响，便于工程应用。     

The shape of premiumness: Logo Shape's effects on perceived brand premiumness and brand preference

Logos are the brands’ visual identity, which can influence brand positioning and contribute to brand success. However, little is known about the effect of logo shape on brand premiumness perception. Thus, we conducted four studies, including one archival dataset analysis, to examine this issue. Results revealed that consumers perceive angular-logo brands as more premium than circular-logo brands. Such logo shape effect is driven by perceived psychological distance between the brand and consumers. We further identified the downstream consequences of perceived brand premiumness. To express status, consumers are more likely to choose angular-logo brands, which are perceived as more premium. However, consumers unmotivated by status-expressing goals will be unaffected by such perceptions. These findings have theoretical implications regarding brand logo and positioning, and practical implications for logo design.     

浅析如何加强当前高等院校文化形态国防建设

高等教育是我国教育体系的重要组成部分,是文化形态国防建设的基础。因此,要加强高等院校文化形态国防建设,巩固国家政权安全,增强国家民族认同感、凝聚力,培养爱国主义、英雄主义精神,树立国家安全高于一切的意识。     

产品市场竞争强度对公司现金股利分配的影响

作为一种外部治理机制,产品市场竞争的强度对公司现金股利分配具有显著的影响。本文所建立的理论模型表明,两者的关系呈倒U形：在产品市场竞争强度达到某一临界值之前,现金股利分配倾向随之提高;但是,在该临界点之后,现金股利分配倾向随之降低。采用迭代主因子法构建了一个合成变量来度量产品市场竞争强度,针对中国上市公司样本数据的实证检验支持了理论分析的结论。     

Can bottles speak volumes? The effect of package shape on how much to buy

Four multi-method studies show that the more elongated a container, the lower its purchase quantity. Study 1, in the lab, shows beer bottles are perceived to contain more than beer cans, particularly for infrequent beer drinkers. Study 2 analyzes scanner data to show that the purchase quantity of cans is 63.66 percent higher than the purchase quantity of bottles. Study 3, a virtual shopping survey, demonstrates these effects are strongest when the context is socializing at home, and Study 4, in the lab, shows results hold only when desired consumption level is constant. Implications for retailers and product managers are offered.     

不同巷道断面形状对围岩稳定性的数值模拟研究

巷道断面形状是影响围岩稳定性的关键因素.为研究断面形状对巷道稳定性的影响,对矩形、梯形和直墙圆拱形三种巷道断面形状进行了数值模拟研究,并分析了不同断面形状巷道围岩的应力特征、变形特征和塑性区域.结果表明:直墙圆拱形巷道围岩稳定性最好,梯形巷道次之,矩形巷道稳定性最差.     

基于集群机理的农业产业集群成长障碍与路径分析
